        To the stockholders of America Online, Inc. and Time Warner Inc.
 
                 A MERGER PROPOSAL--YOUR VOTE IS VERY IMPORTANT
 
   America Online and Time Warner have agreed to combine in a merger of equals.
The new corporation will be named AOL Time Warner Inc. We are proposing the
merger because we believe the combined strengths of our two companies will
enable us to build the world's preeminent, fully integrated media and
communications company. We believe that the merger will benefit the
stockholders of both companies and we ask for your support in voting for the
merger proposals at our special meetings.
 
   When the merger is completed:
 
  .  America Online common stockholders will receive one share of AOL Time
     Warner common stock for each share they own;
 
  .  Time Warner common stockholders will receive 1.5 shares of AOL Time
     Warner common stock for each share they own;
 
  .  Time Warner series LMCN-V common stockholders will receive 1.5 shares of
     substantially identical AOL Time Warner series LMCN-V common stock for
     each share they own; and
 
  .  Time Warner preferred stockholders will receive one share of a
     corresponding series of substantially identical AOL Time Warner
     preferred stock for each share of each series of Time Warner preferred
     stock they own, with appropriate adjustment to the voting rights and
     conversion ratio for each series.
 
   AOL Time Warner intends to apply to list its common stock on the New York
Stock Exchange under the symbol "AOL."
 
   The boards of directors of both America Online and Time Warner have approved
the merger and recommend that their respective stockholders vote FOR the merger
proposals as described in the attached materials. Information about the merger
is contained in this joint proxy statement-prospectus. We urge you to read this
material, including the section describing risk factors relating to the merger
that begins on page 23.
 
   The dates, times and places of the meetings are as follows:
 
For America Online stockholders:             For Time Warner stockholders:
 
   Your vote is very important, regardless of the number of shares you own.
Please vote as soon as possible to make sure that your shares are represented
at the meeting. To vote your shares, you may complete and return the enclosed
proxy card or voting instructions or you may be able to submit your proxy or
voting instructions by telephone or the Internet. If you are a holder of
record, you may also cast your vote in person at the special meeting. If your
shares are held in an account at a brokerage firm or bank, you must instruct
them on how to vote your shares. If you do not vote or do not instruct your
broker or bank how to vote, it will have the same effect as voting against the
merger.

   We strongly support this combination of our companies and join with our
boards of directors in enthusiastically recommending that you vote in favor of
the merger.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER
 
Q: Why are America Online and Time Warner proposing the merger?
 
A: We are proposing the merger because we believe the combined strengths of our
   two companies will enable us to build the world's preeminent, fully
   integrated media and communications company. The merger will combine Time
   Warner's broad array of media, entertainment and news brands and its
   technologically advanced broadband delivery systems with America Online's
   extensive Internet franchises, technology and infrastructure to create a new
   company capable of enhancing consumers' access to the broadest selection of
   high-quality content and interactive services. By combining the leading
   interactive services and media companies, AOL Time Warner will create the
   potential for stronger operating and financial results than either company
   could achieve on its own.
 
Q: What will I receive in the merger?
 
A: Stockholders of America Online and Time Warner will receive the following in
   the merger:
 
  .  America Online common stockholders will receive one share of AOL Time
     Warner common stock for each share they own;
 
  .  Time Warner common stockholders will receive 1.5 shares of AOL Time
     Warner common stock for each share they own;
 
  .  Time Warner series LMCN-V common stockholders will receive 1.5 shares of
     substantially identical AOL Time Warner series LMCN-V common stock for
     each share they own; and
 
  .  Time Warner preferred stockholders will receive one share of a
     corresponding series of substantially identical AOL Time Warner
     preferred stock for each share of each series of Time Warner preferred
     stock they own, with appropriate adjustment to the voting rights and
     conversion ratio for each series.
 
Q: What stockholder approvals are needed?
 
A: For America Online, the affirmative vote of the holders of a majority of the
   outstanding shares of America Online's common stock is required to adopt the
   merger agreement.
 
   For Time Warner, the affirmative vote of a majority of the voting power of
   the outstanding shares of Time Warner's common stock and preferred stock,
   voting together as one group, is required to adopt the merger agreement.
 
Q: What do I need to do now?
 
A: After carefully reading and considering the information contained in this
   joint proxy statement-prospectus, please respond by completing, signing and
   dating your proxy card or voting instructions and returning it in the
   enclosed postage paid envelope, or, if available, by submitting your proxy
   or voting instructions by telephone or through the Internet, as soon as
   possible so that your shares may be represented at your 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.

      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 America Online or Time Warner, as appropriate,
   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 at a later date, using the same
   procedures, in which case your later submitted proxy will be recorded and
   your earlier proxy 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 AOL Time Warner. Please do not send in your stock certificates
   with your proxy.
 
Q: Who is the exchange agent for the merger?
 
A: [      ] is the exchange agent.
 
Q: Where will my shares of AOL Time Warner common stock be listed?

   Stock Exchange under the symbol "AOL."
 
Q: Will I receive dividends on my AOL Time Warner shares?
 
A: AOL Time Warner does not currently intend to pay dividends on its common
   stock. AOL Time Warner will pay dividends on each series of its preferred
   stock in accordance with their terms.
 
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 during the fall of 2000.

   Founded in 1985, America Online is the world's leader in interactive
services, Web brands, Internet technologies and electronic commerce services.
 
   America Online has two major lines of businesses organized into four product
groups:
 
  .  the Interactive Online Services business, comprised of the Interactive
     Services Group, the Interactive Properties Group and the AOL
     International Group; and
 
  .  the Enterprise Solutions business, comprised of the Netscape Enterprise
     Group.
 
   The product groups are described below.
 
The Interactive Services Group develops and operates branded interactive
services, including:
 
  .  the AOL service, a worldwide Internet online service with more than 21
     million members;
 
  .  the CompuServe service, a worldwide Internet online service with more
     than 2.5 million members;
 
  .  the Netscape Netcenter, an Internet portal with more than 25 million
     registered users;
 
  .  the AOL.com Internet portal; and
 
  .  the Netscape Communicator client software, including the Netscape
     Navigator browser.
 
   The Interactive Properties Group is built around branded properties that
operate across multiple services and platforms, such as:
 
  .  Digital City, Inc., the No. 1 branded local content network and
     community guide on the AOL service and the Internet;
 
  .  ICQ, the world's leading communications portal that provides instant
     communications and chat technology;
 
 
                                       4

<PAGE>
 
  .  MovieFone, Inc., the nation's No. 1 movie guide and ticketing service
     provided through an interactive telephone service and on the AOL service
     and the Internet; and
 
  .  Internet music brands Spinner.com, Winamp and SHOUTcast.
 
   The AOL International Group oversees the AOL and CompuServe services outside
the United States, as well as the Netscape Online service in the United
Kingdom.
 
   The Netscape Enterprise Group focuses on providing businesses with a range
of software products, technical support, consulting and training services.
These products and services enable businesses and users to share information,
manage networks and facilitate electronic commerce.
 
   America Online also has a strategic alliance with Sun Microsystems, Inc., a
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 December 21, 1999, America Online and MapQuest.com,
Inc. entered into a merger agreement pursuant to which MapQuest, a leader in
online destination information solutions, will become a wholly owned subsidiary
of America Online. The merger is subject to customary conditions, including
regulatory consents and MapQuest stockholder approval, and is expected to be
completed prior to the merger of America Online and Time Warner.
 
   America Online has been named as a defendant in several putative class
action lawsuits. 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.

   AOL Time Warner is a newly formed corporation that has not, to date,
conducted any activities other than those incident to its formation, the
matters contemplated by the merger agreement and the preparation of this joint
proxy statement-prospectus. Upon completion of the merger, America Online and
Time Warner will each become a wholly owned subsidiary of AOL Time Warner. The
business of AOL Time Warner will be the combined businesses currently conducted
by America Online and Time Warner.
 
The Structure of the Merger (see page 56)
 
   To accomplish the combination of their businesses, America Online and Time
Warner jointly formed a new company, AOL Time Warner, with two subsidiaries,
America Online Merger Sub Inc. and Time Warner Merger Sub Inc. At the time the
merger is completed:
 
  .  America Online Merger Sub will be merged into America Online, and
     America Online will be the surviving corporation; and
 
  .  Time Warner Merger Sub will be merged into Time Warner, and Time Warner
     will be the surviving corporation.
 
As a result, America Online and Time Warner will each become a wholly owned
subsidiary of AOL Time Warner.

financial point of view, to the holders of Time Warner common stock and series
common stock. The full text of this opinion is attached as Annex F to this
joint proxy statement-prospectus. Time Warner urges its stockholders to read
the opinion of Morgan Stanley in its entirety.
 
Stockholder Approvals (see page 26)
 
   Approval of America Online's Stockholders. The affirmative vote of the
holders of a majority of the shares of America Online common stock outstanding
as of the record date is required to adopt the merger agreement. As of the
record date, America Online directors and executive officers and their

   Approval of Time Warner's Stockholders. The affirmative vote of the holders
of a majority of the voting power of the shares of Time Warner common stock and
Time Warner preferred stock outstanding as of the record date, voting together
as one group, is required to adopt the merger agreement. Time Warner common
stockholders are entitled to one vote per share, and the Time Warner preferred
stockholders are entitled to four votes per share. The holders of the Time
Warner series LMCN-V common stock are not entitled to vote on the merger
proposal. As of the record date, Time Warner directors and executive officers
and their affiliates (including R.E. Turner) owned approximately [   ] shares
of Time Warner common stock, which represented approximately [ ]% of the voting
power of Time Warner capital stock entitled to vote at the Time Warner special
meeting. Mr. Turner and his affiliates who are parties to the voting agreement
with America Online have agreed to vote substantially all their shares of Time
Warner common stock (which represent approximately [  ]% of the voting power of
Time Warner capital stock entitled to vote at the Time Warner special meeting)
in favor of the adoption of the merger agreement.
 
   Procedures for Voting Your Shares. Your vote is very important, regardless
of the number of shares you own. Please vote as soon as possible to make sure
that your shares are represented at the meeting. You may vote your shares by
signing your proxy card and mailing it in the enclosed return envelope, or you
may be able to submit your proxy or voting instructions by telephone or by the
Internet. If you are a holder of record, you may vote in person at the special
meeting. If you do not include instructions on how to vote your
 
                                       9

<PAGE>
 
properly executed proxy card, your shares will be voted FOR adoption of the
merger agreement. If your shares are held in an account at a brokerage firm or
bank, your broker will vote your shares only if you provide instructions on how
to vote by following the information provided to you by your broker. If you do
not vote, it will have the same effect as voting against the merger.
 
   Procedure for Changing Your Vote. You can change your vote at any time
before your proxy is voted at the special meeting of your company's
stockholders. You can do this in one of three ways. First, you can send a
written notice stating that you are revoking your proxy. Second, you can
complete and submit a new proxy card. If you choose either of these two
methods, you must submit your notice of revocation or your new proxy for
America Online shares to the Corporate Secretary of America Online at the
address on page 27 and for Time Warner shares to the Corporate Secretary of
Time Warner at the address on page 27. If your shares are held in an account at
a brokerage firm or bank, you should contact your broker to change your vote.
Third, if you are a holder of record, you can attend the special meeting of
your company's stockholders and vote in person. To revoke a proxy previously
submitted electronically through the Internet or by telephone, you may simply
submit a proxy at a later date, using the same procedures, in which case your
later submitted proxy will be recorded and your earlier proxy will be revoked.
 
   Appraisal Rights. Under Delaware law, America Online stockholders and Time
Warner common stockholders are not entitled to appraisal rights in connection
with the merger. However, holders of the Time Warner series LMCN-V common stock
and Time Warner preferred stock who submit a written demand for appraisal of
their shares and who comply with the other applicable statutory procedures
under Delaware law (including, in the case of Time Warner preferred
stockholders, not voting in favor of adoption of the merger agreement) will be
entitled to appraisal rights and to receive payment in cash for the fair market
value of their shares as determined by the Delaware Chancery Court. For a more
complete description of these appraisal rights, see "The Merger--Appraisal
Rights."

Board of Directors and Management Following the Merger (see page 122)
 
   We have agreed that, initially, half of the 16 directors of AOL Time Warner
will be selected by America Online, and half will be selected by Time Warner.
We are required to maintain this equal membership for one year after the merger
is completed.
 
   Stephen M. Case, Chairman and Chief Executive Officer of America Online,
will become Chairman of the Board of AOL Time Warner. Gerald M. Levin, Chairman
and Chief Executive Officer of Time Warner, will become Chief Executive Officer
of AOL Time Warner. R. E. Turner, Vice Chairman of Time Warner, will become
Vice Chairman of AOL Time Warner. Richard D. Parsons, President of Time Warner

Interests of Directors and Executive Officers in the Merger (see page 54)

to, the interests of their company's stockholders.

Treatment of Stock Options and Restricted Stock (see page 58)
 
   America Online. When the merger is completed, each outstanding America
Online employee stock option will be converted into an option to purchase
shares of AOL Time Warner common stock at an exercise price per share equal to
the exercise price per share of America Online common stock subject to the
option before the conversion. In addition, each outstanding restricted share of
America Online common stock will be converted into one restricted share of AOL
Time Warner common stock. As a result of the completion of the merger,
substantially all America Online employee stock options and shares of
restricted stock outstanding on January 10, 2000, by their terms, will vest and
become exercisable or free of restrictions, as the case may be, upon the
earliest to occur of (1) their normal vesting date, (2) the first anniversary
of the completion of the merger and (3) the employee's termination without
cause or constructive termination.
 
   Time Warner. When the merger is completed, each outstanding Time Warner
stock option will be converted into an option to purchase the number of shares
of AOL Time Warner common stock that is equal to the product of 1.5 multiplied
by the number of shares of Time Warner common stock that would have been
obtained before the merger upon the exercise of the option, rounded to the
nearest whole share. The exercise price per share will be equal to the exercise
price per share of Time Warner common stock subject to the option before the
conversion divided by 1.5. In addition, each outstanding restricted share of
Time Warner common stock will be converted into the number of restricted shares
of AOL Time Warner common stock that is equal to the product of 1.5 multiplied
by the shares of Time Warner common stock subject to the award. Each Time
Warner stock option outstanding on January 9, 2000, by its terms, accelerated
and became fully vested, and each share of restricted Time Warner common stock
outstanding on that date, by its terms, became fully vested and free of
restrictions.
 
Tax Consequences (see page 59)
 
   We have structured the merger so that America Online, Time Warner and their
respective stockholders who exchange their shares for shares of AOL Time Warner
capital stock will not recognize gain or loss for United States federal income
tax purposes in connection with the merger, except for taxes payable because of
cash received by Time Warner stockholders instead of fractional shares.
 
Overview of the Merger Agreement (see page 64)
 
   Conditions to the Completion of the Merger. Each of America Online's and
Time Warner's obligation to complete the merger is subject to the satisfaction
or waiver of specified conditions, including those listed below:
 
  .  the merger agreement must be adopted by both the America Online and Time
     Warner stockholders;
 
  .  no law, injunction or order preventing the completion of the merger may
     be in effect;
 
  .  the applicable waiting period under U.S. antitrust laws must expire or
     be terminated;
 
  .  we must obtain other regulatory approvals from domestic and foreign
     governmental entities;
 
  .  the shares of AOL Time Warner common stock to be issued in the merger
     must have been approved for listing on the New York Stock Exchange;
 
  .  we must have complied with our respective covenants in the merger
     agreement;
 
  .  our respective representations and warranties in the merger agreement
     must be true and correct; and

     merger will qualify as a tax-free exchange or reorganization.
 
 
                                       11

<PAGE>
 
   Termination of the Merger Agreement. America Online and Time Warner can
jointly agree to terminate the merger agreement at any time. Either company may
also terminate the merger agreement if:
 
  .  the merger is not completed on or before May 31, 2001, so long as the
     failure to complete the merger is not the result of the failure by that
     company to fulfill any of its obligations under the merger agreement;
 
  .  government actions do not permit the completion of the merger;
 
  .  either company's stockholders do not vote to adopt the merger agreement
     at a duly held meeting of that company's stockholders;
 
  .  the board of directors or officers of the other company fail to take
     required actions as described on page 70; or
 
  .  the other company breaches its representations, warranties or covenants
     in the merger agreement in a material way.
 
   Termination Fees. The merger agreement provides that in several
circumstances, America Online or Time Warner may be required to pay termination
fees to the other party as described on pages 70 and 71.
 
   "No Solicitation" Provisions. The merger agreement contains detailed
provisions prohibiting America Online and Time Warner from seeking an
alternative transaction. These "no solicitation" provisions prohibit America
Online and Time Warner, as well as their officers, directors, subsidiaries and
representatives, from taking any action to solicit an acquisition proposal as
described on page 66. The merger agreement does not, however, prohibit either
party or its respective board of directors from considering, and potentially
recommending, an unsolicited bona fide written superior proposal from a third
party as described on pages 67 and 68.
 
   Regulatory Matters. Under U.S. antitrust laws, we may not complete the
merger until we have notified the Antitrust Division of the Department of
Justice and the Federal Trade Commission of the merger and filed the necessary
report forms, and until a required waiting period has ended. We have filed the
required information and materials with the Department of Justice and the
Federal Trade Commission.
 
   To complete the merger, we must also obtain the approval of the Federal
Communications Commission, and a number of state and local authorities. The
Federal Communications Commission and these state and local authorities have
not completed their reviews of the merger.
 
   In addition, both America Online and Time Warner are required to make
filings with or obtain approvals from the European Commission and other
international regulatory authorities in connection with the merger, including
regulatory authorities in Brazil, Canada and South Africa.
 
   We cannot assure you that we will obtain all regulatory approvals to
complete the merger or that the granting of these approvals will not involve
the imposition of conditions to the completion of the merger or require changes
to the terms of the merger. These conditions or changes could result in the
conditions to the merger not being satisfied.
 
   Accounting Treatment. We intend to account for the merger under the purchase
method of accounting for business combinations.
 
   Completion and Effectiveness of the Merger. We will complete the merger when
all of the conditions to completion of the merger are satisfied or waived in
accordance with the merger agreement. The merger will
 
                                       12

<PAGE>
 
become effective when we file certificates of merger with the State of
Delaware. We expect to complete the merger during the fall of 2000.
 
Stock Option Agreements (see page 74)
 
   Each of America Online and Time Warner has granted the other company an
option to purchase up to 19.9% of its outstanding shares. An option becomes
exercisable if the grantee becomes entitled to receive the larger of the two
termination fees payable by the grantor of the option under the merger
agreement as described on page 75. The grantee's profit under its stock option
agreement is capped at the amount of the larger of the two termination fees
payable by the grantor under the merger agreement.
 
Voting Agreement (see page 78)
 
   America Online has entered into a voting agreement with Mr. Turner and his
affiliates who are parties to the agreement pursuant to which these Time Warner
stockholders have agreed to vote substantially all their shares of Time Warner
common stock in favor of the adoption of the merger agreement. As of the record
date, these stockholders owned shares representing approximately [  ]% of the
voting power of Time Warner capital stock entitled to vote at the Time Warner
special meeting.

   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. 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
 
                                       14

<PAGE>
 
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 $385 million related to the
write-off of previously capitalized deferred subscriber acquisition costs, $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. 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. For the fiscal years ended on or before June 30, 1997, EBITDA does
    not add back the amortization of subscriber acquisition costs. 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.
 
      Ratio of Earnings to Combined Fixed Charges and Preferred Dividends
 
   The following table sets forth the ratio of earnings to combined fixed
charges and preferred dividends for the three months ended September 30, 1999
and for each of the last five fiscal years.

</TABLE>

 
   For purposes of computing the ratio of earnings to combined fixed charges
and preferred dividends, earnings represent earnings from continuing operations
before income taxes plus interest expense on indebtedness, amortization of debt
discount and the portion of rent expense deemed representative of an interest
factor. Fixed charges include interest on indebtedness (whether expensed or
capitalized), amortization of debt discount and the portion of rent expense
deemed representative of an interest factor. For the years ended June 30, 1997
and 1995, the deficiency of earnings to combined fixed charges and preferred
dividends totaled $420 million and $36 million, respectively.

                                  TIME WARNER
 
                       Selected Historical Financial Data
 
   The selected historical financial data of Time Warner have been derived from
the audited historical consolidated financial statements and related notes of
Time Warner for each of the years in the five-year period ended December 31,
1998 and the unaudited consolidated financial statements for the nine months
ended September 30, 1999 and 1998. The historical data are only a summary, and
you should read them in conjunction with the historical financial statements
and related notes contained in the annual and quarterly reports of Time Warner
which have been incorporated by reference into this joint proxy statement-
prospectus.
 
   The selected historical financial data for the nine months ended September
30, 1999 reflect the consolidation of TWE and its related companies,
retroactive to the beginning of 1999. We refer to TWE and its related companies
as the "entertainment group." The selected historical financial data for all
prior periods have not been changed. However, in order to enhance
comparability, pro forma financial information for 1998 reflecting the
consolidation of the entertainment group has been presented.
 
   The selected historical financial data for 1998 reflect (a) the transfer of
cable television systems (or interests therein) serving approximately 650,000
subscribers that were formerly owned by subsidiaries of Time Warner to the TWE-
Advance Newhouse Partnership, subject to approximately $1 billion of debt, in
exchange for common and preferred interests in the partnership, as well as

approximately $1.55 billion of net proceeds from the issuance of Time Warner's
series M preferred stock to reduce outstanding indebtedness and (b) the
acquisitions of Turner Broadcasting System, Inc. and Cablevision Industries

their direct and indirect interests in TWE, resulting in (i) the issuance of an
aggregate 29.3 million shares of Time Warner preferred stock having a total
liquidation preference of $2.926 billion and 5.2 million shares of Time Warner
common stock and (ii) the assumption or incurrence of approximately $1.3
billion of indebtedness.

(1) EBITDA consists of business segment operating income (loss) before
    depreciation and amortization. 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 performance
    of Time Warner, 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.
 
   Significant Events Affecting Time Warner's Operating Trends. The
comparability of Time Warner's operating results is affected by a number of
significant and nonrecurring items recognized in some periods. For the nine
months ended September 30, 1999, these items included (a) net pretax gains of
approximately $1.248 billion relating to the sale or exchange of cable
television systems and investments, (b) a net pretax gain of approximately $215
million from the early termination of a long-term video distribution agreement,
(c) a pretax gain of approximately $115 million relating to the initial public
offering of a 20% interest in Time Warner Telecom, Inc. and (d) an
extraordinary loss of approximately $12 million on the retirement of debt. For
the full year 1998, significant and nonrecurring items included (a) net pretax
gains of approximately $108 million relating to the sale or exchange of cable
television systems and investments, (b) a pretax charge of approximately $210
million principally to reduce the carrying value of an interest in Primestar,
Inc. and (c) a one-time increase in preferred dividend requirements of
approximately $234 million relating to the premium paid in connection with Time
Warner's redemption of its series M preferred stock. For 1997, significant and
nonrecurring items included (a) net pretax gains of approximately $212 million
relating to the sale or exchange of cable television systems and investments,
(b) a pretax gain of approximately $200 million relating to the disposal of an
interest in Hasbro, Inc. and the related redemption of certain mandatorily
redeemable preferred securities of a subsidiary, (c) a pretax gain of
approximately $250 million relating to the sale of an interest in E!
Entertainment Television, Inc. and (d) an extraordinary loss of approximately
$55 million on the retirement of debt. For 1996, significant and nonrecurring
items included an extraordinary loss of approximately $35 million on the
retirement of debt. For 1995, significant and nonrecurring items included (a)
pretax losses of
 
                                       17

<PAGE>
 
approximately $85 million relating to certain businesses and joint ventures
owned by Time Warner's music division that were either restructured or closed
and (b) an extraordinary loss of approximately $42 million on the retirement of
debt.
 
   To assess meaningfully underlying operating trends from period to period,
Time Warner's management believes that the results of operations for each
period should be analyzed after excluding the effects of these significant
nonrecurring items. The following summary adjusts Time Warner'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 individually should consider the types of events and
transactions for which adjustments have been made.

                        TIME WARNER ENTERTAINMENT GROUP
 
                       Selected Historical Financial Data
 
   Since 1993, the entertainment group had not been consolidated by Time Warner
for financial reporting purposes because a subsidiary of MediaOne Group, which
is a limited partner of TWE, had rights that allowed it to participate in the
management of TWE's businesses. However, in August 1999, MediaOne's management
rights over TWE terminated. As a result, retroactive to the beginning of 1999,
the entertainment group has been consolidated by Time Warner.
 
   The selected financial data of the entertainment group have been derived
from and should be read in conjunction with the Time Warner selected financial
information previously presented, the consolidated financial statements and
other financial data of TWE contained in Time Warner's Annual Report on Form
10-K for the year ended December 31, 1998 and with the unaudited consolidated
condensed financial statements and other financial information of TWE contained
in Time Warner's Quarterly Report on Form 10-Q for the quarter ended
September 30, 1999. The historical financial information is only a summary and
you should read it in conjunction with the historical financial statements of
Time Warner and TWE, which have been incorporated by reference in this joint
proxy statement-prospectus.
 
   The selected historical financial data for 1998 reflect (a) the TWE-A/N
Transfers effective as of January 1, 1998, (b) the transfer of Time Warner
Cable's direct broadcast satellite operations to Primestar, Inc. effective as
of April 1, 1998, (c) the formation of the Road Runner joint venture to operate
and expand Time Warner Cable's and MediaOne's existing high-speed online
businesses, effective as of June 30, 1998, (d) the reorganization of Time
Warner Cable's business telephony operations into a separate entity now named
Time Warner Telecom Inc., effective as of July 1, 1998 and (e) the formation of
a joint venture in Texas that owns cable television systems serving
approximately 1.1 million subscribers, effective as of December 31, 1998. The
selected historical financial data for 1995 reflects (a) formation of the TWE-
Advance Newhouse Partnership, effective as of April 1, 1995, (b) the
consolidation of Paragon Communications, effective as of July 6, 1995 and (c)
the deconsolidation of Six Flags Entertainment Corporation resulting from the
disposition by TWE of a 51% interest in Six Flags, effective as of June 23,
1995.

  Significant Events Affecting the Time Warner Entertainment Group's Operating
Trends. The comparability of the entertainment group's operating results is
affected by certain significant and nonrecurring items recognized in certain
periods. For 1999, these items included (a) net pretax gains of approximately
$1.118 billion relating to the sale or exchange of cable television systems and
investments and (b) a net pretax gain of approximately $215 million from the
early termination of a long-term video distribution agreement. For 1998,
significant and nonrecurring items included (a) net pretax gains of
approximately $90 million relating to the sale or exchange of cable television
systems and investments and (b) a pretax charge of approximately $210 million
principally to reduce the carrying value of an interest in Primestar. For 1997,
significant and nonrecurring items included (a) net pretax gains of
approximately $200 million relating to the sale or exchange of cable television
systems and investments, (b) a pretax gain of approximately $250 million
relating to the sale of an interest in E! Entertainment Television, Inc. and
(c) an extraordinary loss of approximately $23 million on the retirement of
debt. For 1995, significant and nonrecurring items included an extraordinary
loss of approximately $24 million on the retirement of debt.
 
   To assess meaningfully underlying operating trends from period to period,
Time Warner's management believes that the results of operations for each
period should be analyzed after excluding the effects of these significant
nonrecurring items. The following summary adjusts the entertainment group'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 individually should consider the types of
events and transactions for which adjustments have been made.

            Selected Unaudited Pro Forma Consolidated Financial Data
 
   The selected unaudited pro forma consolidated financial data of AOL Time
Warner have been derived from the unaudited pro forma consolidated condensed
financial statements included elsewhere in this joint 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: (1) a June 30
fiscal-year basis, which is consistent with America Online's historical fiscal
year-end and (2) 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. Management believes 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.

--------
(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
     performance of AOL Time Warner, 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.
 
(2)  EBITDA includes a number of significant and nonrecurring items. The
     aggregate effect of those items for each period, as well as the adjusted
     EBITDA excluding such amounts, is as follows:

                  UNAUDITED COMPARATIVE PER SHARE INFORMATION
 
   We present below per common share data regarding the income, cash dividends
declared and book value of America Online and Time Warner on both historical
and unaudited pro forma consolidated bases and on a per share equivalent
unaudited pro forma basis for Time Warner. We have derived the unaudited pro
forma consolidated per share information from the unaudited pro forma
consolidated condensed financial statements presented elsewhere in this joint
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 per share data are presented on two different
bases: (1) a June 30 fiscal-year basis, which is consistent with America
Online's historical fiscal year-end and (2) 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. Management believes 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. You should read the information below in conjunction with the financial
statements and accompanying notes of America Online and Time Warner that are

   The Time Warner per share equivalent pro forma data are calculated by
multiplying the AOL Time Warner per share amounts by 1.5, the exchange ratio to
AOL Time Warner common stock. The America Online per share equivalents remain
unchanged, as the exchange ratio to AOL Time Warner common stock is one to one.

                                  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 shares of AOL Time Warner stock that you receive may be less
than the value of your shares of America Online stock or Time Warner stock.
 
   Upon completion of the merger, all shares of America Online common stock and
Time Warner common stock will be automatically converted into shares of AOL
Time Warner common stock. Similarly, all shares of Time Warner LMCN-V series
common stock will be automatically converted into shares of LMCN-V series
common stock of AOL Time Warner and all shares of Time Warner preferred stock
will be automatically converted into shares of a corresponding series of AOL
Time Warner preferred stock. The ratios on which the shares will be converted
are fixed, and there will be no adjustment for changes in the market price of
either America Online common stock or Time Warner common stock. Neither party
is permitted to "walk away" from the merger or resolicit the vote of its
stockholders solely because of changes in the market price of either party's
common stock. America Online common stock has historically experienced
significant volatility. Stock price changes may result from a variety of
factors that are beyond the control of America Online and Time Warner,
including changes in their businesses, operations and prospects, regulatory
considerations and general market and economic conditions.
 
   The market value of the shares of AOL Time Warner stock that will be
received in exchange for shares of America Online common stock and shares of
Time Warner stock in the merger will not be known at the time stockholders of
America Online and stockholders of Time Warner vote on the adoption of the
merger agreement, because the shares of AOL Time Warner common stock will not
trade publicly until the completion of the merger. Shares of America Online
common stock and shares of Time Warner common stock may have a greater market
value than the shares of AOL Time Warner common stock for which they are
exchanged.
 
The combination of America Online and Time Warner to form an integrated media
and communications company creates a new business model that the marketplace
may have difficulty valuing.
 
   The market value of shares of common stock generally reflects a "multiple"
of selected measures of financial performance, such as operating profits or
earnings per share. The market price of shares of common stock of Internet
companies, such as America Online, typically reflects a higher multiple of the
underlying measures of financial performance than does the market price of
shares of common stock of media companies, such as Time Warner. The multiple
for shares of AOL Time Warner common stock may be similar to the multiple for
shares of America Online common stock, or it may be similar to the multiple for
shares of Time Warner common stock, or it may reflect a "blending" of the two.
AOL Time Warner will be the first global, fully integrated media and
communications company, and financial analysts and investors may have
difficulty identifying and applying measures of financial performance that
reflect the value of the combined company. As a result, shares of AOL Time
Warner common stock may not achieve a valuation in the public trading market
that fully reflects the true value of the combined company, including its
synergies and benefits.
 
AOL Time Warner may fail to realize the anticipated benefits of the merger.
 
   The success of the merger will depend, in part, on the ability of AOL Time
Warner to realize the anticipated growth opportunities and synergies from
combining the businesses of America Online with the businesses of Time Warner.
To realize the anticipated benefits of this combination, members of the
management team of AOL Time Warner must develop strategies and implement a
business plan that will:
 
  .  effectively combine Time Warner's media, entertainment and news brands
     and its broadband delivery systems with America Online's interactive
     services, technology and infrastructure;
 
 
                                       23

<PAGE>
 
  .  successfully use the anticipated opportunities for cross-promotion and
     sales of the products and services of Time Warner and America Online and
     for increasing revenues from advertising and e-commerce;
 
  .  effectively and efficiently integrate the policies, procedures and
     operations of America Online and Time Warner;
 
  .  successfully retain and attract key employees of the combined company,
     including operating management and key technical personnel, during a
     period of transition and in light of the competitive employment market;
     and
 
  .  while integrating the combined company's operations, maintain adequate
     focus on the core businesses of AOL Time Warner in order to take
     advantage of competitive opportunities and to respond to competitive
     challenges.
 
   If members of the management team of AOL Time Warner are not able to develop
strategies and implement a business plan that achieves these objectives, the
anticipated benefits of the merger may not be realized. In particular,
anticipated growth in revenue, earnings before interest, taxes and
amortization, or "EBITA," earnings before interest, taxes, depreciation and
amortization, or "EBITDA," and cash flow may not be realized, which would have
an adverse impact on AOL Time Warner and the market price of shares of AOL Time
Warner common stock.
 
Directors of America Online and Time Warner have potential conflicts of
interest in recommending that you vote in favor of adoption of the merger
agreement.
 
   A number of directors of America Online and a number of directors of Time
Warner who recommend that you vote in favor of the adoption of the merger
agreement have employment or severance agreements or benefit arrangements that
provide them with interests in the merger that differ from yours. Following
completion of the merger, Stephen M. Case, Chairman and Chief Executive Officer
of America Online, will serve as Chairman of the Board of AOL Time Warner, and
Robert W. Pittman, President and Chief Operating Officer of America Online,
will serve as Co-Chief Operating Officer of AOL Time Warner. In addition,
Gerald M. Levin, Chairman and Chief Executive Officer of Time Warner, will
serve as Chief Executive Officer of AOL Time Warner, Richard D. Parsons,
President of Time Warner, will serve as Co-Chief Operating Officer of AOL Time
Warner and R.E. Turner, Vice Chairman of Time Warner will serve as Vice
Chairman of AOL Time Warner.
 
   The receipt of compensation or other benefits in the merger (including the
vesting of stock options and restricted stock), or the continuation of
indemnification arrangements for current directors of America Online and Time
Warner 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.
 
AOL Time Warner may be subject to adverse regulatory conditions.
 
   Before the merger may be completed, various approvals must be obtained from
or notifications submitted to, among others, competition authorities in the
United States and abroad, the Federal Communications Commission, and numerous
state and local authorities. Many of these governmental entities from whom
approvals are required may attempt to condition their approval of the merger,
or of the transfer to the combined company of licenses and other entitlements,
on the imposition of certain regulatory conditions that may have the effect of
imposing additional costs on AOL Time Warner or of limiting AOL Time Warner's
revenues. In addition, the regulatory environment in which AOL Time Warner's
businesses will operate is complex and subject to change, and adverse changes
in that environment could have either of these adverse effects.

     preferred stock, Time Warner series I preferred stock and Time Warner
     series J preferred stock is entitled to four votes on all matters
     properly submitted to the Time Warner stockholders.
 
   The holders of the Time Warner series LMCN-V common stock are not entitled
to vote on the merger proposal.
 
   As of the record date, Time Warner directors and executive officers and
their affiliates (including Mr. Turner) owned approximately [ ]% of the voting

meeting. Mr. Turner and his affiliates who are parties to the voting agreement
with America Online have agreed to vote substantially all their shares of Time
Warner common stock (which represent approximately [  ]% of the voting power of
Time Warner capital stock entitled to vote at the Time Warner special meeting)
in favor of the adoption of the merger agreement.

Proxies
 
   All shares of America Online common stock represented by properly executed
proxies or voting instructions received before or at the America Online special
meeting and all shares of Time Warner common stock and preferred stock
represented by properly executed proxies or voting instructions received before
or at the Time Warner special meeting will, unless the proxies or voting
instructions are revoked, be voted in accordance with the instructions
indicated on those proxies or voting instructions. If no instructions are
indicated on a properly executed proxy card or voting instructions, the shares
will be voted FOR adoption of the merger agreement. You are urged to mark the
box on the proxy card to indicate how to vote your shares. A Time Warner
stockholder of record may not appoint more than three persons to act as his or
her proxy at the Time Warner special meeting.
 
   If a properly executed proxy card or voting instruction is returned and the
stockholder has abstained from voting on adoption of the merger agreement, the
America Online common stock or Time Warner common stock or preferred stock
represented by the proxy or voting instructions 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 them on how to vote your shares. If an executed proxy card is returned
by a broker or bank holding shares 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.
 
   Because adoption of the merger agreement requires, in the case of America
Online, the affirmative vote of at least a majority of the shares of America
Online's common stock outstanding on the record date and, in the case of Time
Warner, the affirmative vote of the holders of a majority of the voting power
of the shares of Time Warner common stock and Time Warner preferred stock
outstanding on the record date, voting together as one group, abstentions,
failures to vote and broker non-votes will have the same effect as a vote
against adoption of the merger agreement.
 
   Neither America Online nor Time Warner expects that any matter other than
adoption of the merger agreement will be brought before its 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 on the proxy card.
 
   A stockholder may revoke his or her proxy at any time before it is voted by:
 
  .  notifying in writing the Corporate Secretary of America Online, Inc. at
     22000 AOL Way, Dulles, Virginia 20166, if you are an America Online
     stockholder, or the Secretary of Time Warner Inc. at 75 Rockefeller
     Plaza, New York, New York 10019, if you are a Time Warner stockholder;
 
  .  granting a subsequently dated proxy; or
 
  .  appearing in person and voting at the special meeting if you are a
     holder of record.
 
   Attendance at the special meeting will not in and of itself constitute
revocation of a proxy.
 
Voting Electronically or by Telephone
 
   Instead of submitting your vote by mail on the enclosed proxy card or voting
instructions, many stockholders will have the option to submit their proxies or
voting instructions electronically 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 your company's stock records
in your name or in the name of a brokerage firm or bank. Stockholders should
check their proxy card or voting instructions forwarded by their broker, bank
or other holder of record to see which options are available.
 
                                       27

   The Internet and telephone procedures 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. We have been advised by counsel that the
procedures that have been put in place are consistent with the requirements of
applicable 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.
 
Solicitation of Proxies
 
   America Online and Time Warner will equally share the expenses incurred in
connection with the printing and mailing of this joint proxy statement-
prospectus. America Online has retained Corporate Investor Communications,
Inc., at an estimated cost of $[   ] plus reimbursement of expenses, to assist
in the solicitation of proxies. Time Warner has retained D.F. King & Co., at an
estimated cost of $[   ] plus reimbursement of expenses, to assist in the
solicitation of proxies. America Online, Time Warner and their respective proxy
solicitors will also request banks, brokers and other intermediaries holding
shares of America Online or Time Warner common stock beneficially owned by
others to send this joint 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 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.

Background of the Merger
 
   In September 1999, Stephen M. Case, Chairman and Chief Executive Officer of
America Online, and Gerald M. Levin, Chairman and Chief Executive Officer of
Time Warner, participated in a meeting of media and technology executives at
the Global Business Dialogue on E-Commerce in Paris. Later in September,
Messrs. Case and Levin participated in a number of meetings at the Fortune
Global Forum and related events, which took place in Shanghai and Beijing.
During the time they spent together at these conferences, Messrs. Case and
Levin discussed a variety of topics related to their businesses. They did not,
however, discuss the possibility of combining their businesses.
 
   In mid-October, Mr. Case spoke with Mr. Levin to suggest that they consider
a business combination involving America Online and Time Warner. Mr. Case
proposed that the combination be accomplished through a stock-for-stock merger
of equals. In addition, Mr. Case proposed that he would serve as chairman of
the combined company and that Mr. Levin would serve as chief executive officer
of the combined company. On October 25, 1999, Messrs. Case and Levin had
another conversation to discuss further these matters.
 
   On November 1, 1999, Messrs. Case and Levin met for dinner and continued
their discussion about a possible business combination, elaborating on the
mutual strategic benefits of a merger of equals and discussing the structure
and implementation of a business combination. That discussion included a
reaffirmation of the fundamental principles of the business combination first
outlined in the mid-October conversation, and ended with a mutual intention to
pursue discussions further.
 
   In conjunction with the initial discussions, the companies began consulting
with various financial and legal advisors about issues raised in the
discussions among their executives. America Online retained Salomon Smith
Barney as its financial advisor and Simpson Thacher & Bartlett and Mintz,
Levin, Cohn, Ferris, Glovsky and Popeo, P.C., as its legal counsel. Time Warner
retained Morgan Stanley as its financial advisor and Cravath, Swaine & Moore as
its legal counsel. Working with these advisors, America Online and Time Warner
began conducting their due diligence investigations using publicly available
materials and began analyses of a possible combination. These consultations
continued throughout the remaining merger discussions.
 
  Following the November 1, 1999 dinner meeting between Messrs. Case and Levin,
Kenneth J. Novack, Vice Chairman of America Online, and Miles Gilburne, then
the Senior Vice President, Corporate Development of America Online, had several
telephone conversations with Richard J. Bressler, Chairman and Chief Executive
Officer of Time Warner Digital Media, to discuss the structure and
implementation of a stock-for-stock merger of America Online and Time Warner.
Over the next two months, Messrs. Novack and Bressler had periodic telephone
conversations to discuss the proposed combination.
 
   On November 9, 1999, Messrs. Novack, Gilburne and Bressler met to continue
to discuss the strategic rationale for a merger, the appropriate exchange ratio
and the governance and management structure of the resulting entity. The
discussions remained at a general level, and no agreement regarding the
specific terms of a possible stock-for-stock merger was reached.
 
                                       29

<PAGE>
 
   Following the November 9, 1999 meeting, Messrs. Novack and Bressler engaged
in numerous telephone discussions concerning a potential merger, culminating in
another meeting among Messrs. Novack, Gilburne and Bressler in New York on
November 16, 1999. During that meeting, there were again discussions, but no
agreement, about an appropriate exchange ratio and a governance and management
structure for the merged entity.
 
   On November 17, 1999, Mr. Case met with R. E. Turner, the Vice Chairman of
Time Warner, to discuss the potential merger and its strategic rationale. Later
in the day, Messrs. Case and Levin met and discussed possible exchange ratios,
but they concluded the meeting at an impasse. The parties determined at this
point to discontinue discussions about a possible combination.
 
   Mr. Novack and Mr. Bressler spoke by telephone on or about December 8, 1999,
concerning the companies' relative market performance and the possibility of
holding a meeting the following week to renew discussions. On December 10,
1999, America Online and Time Warner entered into a confidentiality agreement
which contained customary standstill provisions. On December 13, 1999, Mr.
Novack and a representative of Salomon Smith Barney met with Mr. Bressler and a
representative of Morgan Stanley in New York to discuss possible structures for
a transaction and pricing terms, including exchange ratios and whether a collar
would be used. The meeting concluded without agreement.
 
   On the morning of December 23, 1999, Mr. Novack, and J. Michael Kelly, Chief
Financial Officer of America Online, and a representative of Salomon Smith
Barney met in Boston with Richard D. Parsons, President of Time Warner, Mr.
Bressler and a representative of Morgan Stanley to continue discussions
regarding a possible transaction. The exchange ratio for a possible merger was
again discussed, but the parties' positions were not materially different than
before, although alternative structures were discussed. The meeting concluded
with no agreement on terms of a possible combination and no additional meetings
or discussions were scheduled.
 
   On January 5, 2000, Mr. Bressler and Mr. Novack renewed contact in a
telephone conversation. On January 6, 2000, Mr. Novack telephoned Mr. Bressler
to invite Mr. Levin and him to meet at Mr. Case's home in Virginia that
evening. The four met that evening for approximately five hours to discuss the
principal terms of a transaction. Messrs. Case and Levin agreed to fix the
ratio for exchanging shares of common stock of Time Warner for shares of common
stock of the combined company at 1.5 to 1, and they agreed in principle on
other principal terms of the merger, subject to the approval of each company's
board of directors and negotiation of definitive agreements.
 
   Beginning on January 7, 2000, America Online, Time Warner and their
respective advisors intensified due diligence activities, communications
coordination and preparation of definitive documentation. On January 8 and 9,
2000, representatives of America Online, Time Warner and their respective
advisors met to conduct due diligence, negotiate the merger agreement and
related agreements, and plan and prepare for the announcement of the merger.
These activities continued throughout the weekend, with negotiations on the
merger agreement continuing through the evening of January 9, 2000.
 
   On January 9, 2000, the board of directors of Time Warner met beginning at
2:00 p.m. at the offices of Cravath, Swaine & Moore to consider the proposed
transaction. At this meeting, Mr. Levin and other members of management
reviewed the transaction with the board, including the strategic reasons for
the proposed transaction, the principal terms of the proposed transaction, a
financial review of the proposed transaction, a review of America Online's
financial condition and business operations and the results of Time Warner's
due diligence review.
 
   Time Warner's internal legal counsel and representatives of Cravath, Swaine
& Moore discussed the board's fiduciary duties in considering a strategic
business combination and further discussed the terms of the merger agreement
and related documents. Representatives of Morgan Stanley presented to Time
Warner's board of directors a summary of its analyses on the strategic
rationale for and financial analyses related to the proposed transaction. In
addition, Morgan Stanley delivered its opinion that the ratio for exchanging
shares of Time Warner common stock and series common stock for shares of common
stock and series common stock of
 
                                       30

<PAGE>
 
AOL Time Warner pursuant to the merger agreement was fair, from a financial
point of view, to holders of Time Warner's common stock and series common
stock. Upon completing its deliberations, the board of directors of Time Warner
unanimously approved the merger agreement and the related agreements and the
transactions contemplated by those agreements, declared them advisable and
resolved to recommend that Time Warner's stockholders adopt the merger
agreement.
 
   Also on January 9, 2000, the board of directors of America Online met
beginning at 5:00 p.m. at the offices of Simpson Thacher & Bartlett to consider
the proposed transaction. Dr. Thomas Middelhoff, Chairman and Chief Executive
Officer of Bertelsmann, AG, chose not to participate in the meeting. At this
meeting, Mr. Case and other members of management reviewed the transaction with
the board, including the strategic reasons for the proposed transaction, the
principal terms of the proposed transaction, a financial review of the proposed
transaction, a review of Time Warner's financial condition and business
operations and the results of America Online's due diligence review.
 
   America Online's internal legal counsel and representatives of Simpson
Thacher & Bartlett discussed the board's fiduciary duties in considering a
strategic business combination and further discussed the terms of the merger
agreement and related documents. Representatives of Salomon Smith Barney
presented to America Online's board of directors a summary of its analyses on
the strategic rationale for and financial analyses related to the proposed
transaction. In addition, Salomon Smith Barney delivered its opinion that the
ratio for exchanging shares of Time Warner common stock for shares of common
stock of AOL Time Warner contemplated by the merger agreement was fair, from a
financial point of view, to America Online. Upon completing its deliberations,
the board of directors of America Online, by action of those present at the
meeting, unanimously approved the merger agreement and related agreements and
the transactions contemplated by those agreements, declared them advisable and
resolved to recommend that America Online's stockholders adopt the merger
agreement.
 
   At the conclusion of the respective board meetings, the boards of directors
of America Online and Time Warner had a brief telephone conference call.
 
   After negotiation of the final terms of the merger agreement and related
agreements, representatives of America Online and representatives of Time
Warner executed the agreements. In addition, Mr. Turner and certain of his
affiliates entered into a voting agreement with America Online pursuant to
which they agreed to vote substantially all of their shares of common stock of
Time Warner in favor of adoption of the merger agreement.
 
   On the morning of January 10, 2000, America Online and Time Warner issued a
joint press release announcing the proposed merger of America Online and Time
Warner.
 
America Online's Reasons for the Merger
 
   America Online's merger with Time Warner will create the world's first fully
integrated Internet-powered media and communications company. America Online's
board of directors believes that AOL Time Warner will be uniquely positioned to
expand the interactive medium's penetration into consumers' everyday lives--
creating major new opportunities to deliver value to stockholders. By combining
the leading interactive services and media companies, AOL Time Warner will
advance the strategic goals of America Online and Time Warner and will provide
the potential for stronger operating and financial results than either company
could achieve on its own.
 
   America Online's Internet resources will drive the digital transformation of
Time Warner's divisions, and Time Warner's resources will advance the
development of next-generation broadband and AOL Anywhere services, as well as
build subscription and advertising and e-commerce growth throughout America
Online's brands and products. With leading global brands, cost-efficient
infrastructure, technological expertise and a shared vision for the Internet
age, the two companies' complementary assets will act as catalysts to
accelerate the growth of both subscription and advertising/e-commerce revenues,
while also creating new business opportunities.
 
 
                                       31

   America Online's success has been guided by the principle that mass market
consumers seek convenience, ease-of-use and trusted brands in their Internet
experience. AOL Time Warner will have an unmatched ability to provide these
through a full range of interactive services delivered across current and
emerging platforms. The combined company will be able to lead the next wave of
Internet growth as interactivity extends beyond the personal computer to the
television, wireless telephone and personal organizers, as well as other
Internet-enabled devices--allowing consumers to access the Internet from
anywhere and at anytime, and making the interactive experience even more
convenient and valuable to them.
 
   America Online's board of directors believes that AOL Time Warner will be
the Internet company most capable of covering so many aspects and so many hours
of consumers' lives daily, thereby becoming increasingly integral and valuable
to mass market consumers.
 
   America Online's board of directors believes the following are key specific
reasons that the merger will be beneficial to America Online and in the best
interest of its stockholders:
 
   Create a Portfolio of World-Class Consumer Brands and Advance Multiple-Brand
Strategy. The board of directors of America Online believes that combining with
Time Warner will dramatically advance America Online's multiple-brand strategy.
Time Warner's leading global consumer brands cover the full spectrum of media
entertainment and information--reaching from broadcast and cable television to
film, music, publishing and the Internet. Together with America Online's family
of premier interactive brands, the combined company will have a valuable
portfolio of brands to deliver to consumers over multiple platforms.
 
   Grow E-Commerce and Advertising Opportunities and Accelerate Multiple
Revenue Stream Strategy. The board of directors of America Online believes the
merger will advance America Online's strategy of multiple revenue streams by
combining with Time Warner, which has grown its revenues across three major
areas that reinforce America Online's: subscriptions, advertising and e-
commerce and content. Putting together Time Warner's content properties with
America Online's Internet and e-commerce infrastructure, AOL Time Warner will
be able to create and distribute e-commerce products and services based on
film, cable, broadcast, music, publishing and media properties. Recent
successful collaborations to promote "Austin Powers: The Spy Who Shagged Me"
with AOL MovieFone and on "You've Got Mail" with Warner Bros. are small
examples of what can be achieved in cross-promotion. The merger also will
expand the opportunities for advertising across platforms and brands, including
interactive properties, publishing, cable and broadcast television.
 
   Advance AOL Anywhere Strategy to Extend and Enhance Communication and
Convenience through Next- Generation Technology. The board of directors of
America Online believes that combining with Time Warner will advance America
Online's utilization of technology to extend and enhance its AOL Anywhere
strategy to expand Internet communication, interactivity and convenience to
devices beyond the personal computer. Time Warner's cable systems will expand
the broadband delivery systems for America Online's interactive services and
act as a catalyst for the development of AOL Plus--America Online's next
generation multi-media/interactive services to personal computers. The
combination also will further America Online's AOL Anywhere strategy of
extending its interactive brands with their hallmark convenience and ease-of-
use to new devices through television, wireless telephone and personal
organizers as well as other companion devices. The merger also will provide a
communications platform that gives AOL Time Warner the capability to offer
instant messaging products and local telephony over cable systems.
 
   Create Substantial Operating Synergies and New Business Opportunities. The
board of directors of America Online believes that the combined company will
benefit from substantial operating synergies as well as major new business
opportunities. The following are representative potential cost synergies and
revenue growth opportunities from the combination with Time Warner:
 
  .  revenue opportunities and synergies in areas such as advertising by
     providing companies "one-stop" shopping for their online as well as
     print and broadcast media advertising campaigns;
 
 
                                       32

<PAGE>
 
  .  increased subscriber growth through cross promotion and marketing
     opportunities between Time Warner's brands and content and America
     Online's brands and interactive services;
 
  .  efficiency in marketing across different platforms and distribution
     systems, including cable, publishing and interactive services;
 
  .  cost synergies in areas such as technology and network infrastructure,
     direct mail and interactive marketing, use of "evergreen" billing
     systems, sales forces and other corporate services; and
 
  .  cost efficiencies in launching and operating interactive extensions of
     Time Warner brands.
 
   In all, management estimated for the board of directors of America Online
that total EBITDA synergies would be approximately $1 billion in the first full
year of operations, producing an EBITDA growth rate of approximately 30% in
that first year. It is anticipated that the combined company will have a
revenue base in excess of $40 billion and EBITDA of approximately $11 billion,
including synergies, in the first full year.
 
   The board of directors also took note of the fact that the merger is with a
long-time business partner of America Online with a proven history of
successful collaborations, including cross-promotion and marketing activities
between the two companies. Both companies also have management teams with
demonstrated ability to manage the integration process of major business
combinations.

  .  the strategic fit of America Online and Time Warner, including the
     belief that the merger has the potential to enhance stockholder value
     through the numerous growth opportunities and synergies resulting from
     combining the two companies' complementary strengths and assets,
     including additional opportunities for e-commerce, growth in
     subscribers, cross-promotions, and operating efficiencies;
 
  .  the opportunities and alternatives available to America Online if the
     merger were not to be undertaken, including pursuing an acquisition of
     or business combination or joint venture with entities other than Time
     Warner and the conclusion that a combination with Time Warner is
     expected to yield greater benefits and is more feasible than the
     alternatives;

<PAGE>
 
  .  the analyses and presentation of Salomon Smith Barney on the financial
     aspects of the proposed merger, and their written opinion to the effect
     that, as of January 9, 2000, and based on and subject to the various
     considerations set forth in its opinion, the exchange ratio of AOL Time
     Warner common stock for shares of Time Warner common stock was fair from
     a financial point of view to America Online;
 
  .  the terms and conditions of the merger agreement, stock option
     agreements and voting agreement, including the fact that the exchange

     affiliates to vote in favor of the merger, the limitations on the
     interim business operations of each of America Online and Time Warner,
     the conditions to consummation of the merger, the right of the parties
     to the merger agreement, under certain circumstances, to respond to,
     evaluate and negotiate with respect to other business combination
     proposals, the circumstances under which the merger agreement could be
     terminated and the size and impact of termination fees associated with a
     termination; the grant of reciprocal options to purchase shares of
     common stock by each company, as well as the advice of America Online's
     financial and legal advisors that these provisions were reasonable in
     the context of the transaction;
 
  .  the corporate governance arrangements established for the transaction,
     including the board composition, designation of key senior management
     and the establishment of an integration committee, which are designed to

  .  the accounting treatment of transaction as a "purchase" transaction,
     including the goodwill that will be recorded on the financial statements
     of AOL Time Warner; and
 
  .  the interests of the officers and directors of America Online and Time
     Warner in the merger, including the matters described under "--Interests
     of Certain America Online Directors and Executive Officers in the
     Merger," and the impact of the merger on America Online's stockholders,
     customers and employees.
 
   The America Online board also considered the potential adverse consequences
of other factors on the proposed merger, including:
 
  .  the challenges of combining the businesses, assets and workforces of two
     major companies and the risks of not achieving the expected operating
     efficiencies or growth;
 
  .  the risk of diverting management focus and resources from other
     strategic opportunities and from operational matters while working to
     implement the merger; and
 
  .  the risk that the merger will not be consummated.
 
   This discussion of the information and factors considered by the America
Online board is not intended to be exhaustive, but includes the material
factors considered. The America Online board did not assign particular weight
or rank to the factors it considered in approving the merger. In considering
the factors described above, individual members of the America Online board may
have given different weight to various ones. The America Online board
considered all these factors as a whole, and overall considered them to be
favorable to and to support its determination.
 
Time Warner's Reasons for the Merger
 
   The board of directors of Time Warner believes that the combination of Time
Warner and America Online will create a preeminent global company that, for the
first time, will fully integrate traditional and new media
 
                                       34

<PAGE>
 
and communications businesses and technologies. The combined company, AOL Time
Warner, will be uniquely positioned to deliver branded information,
entertainment and communications services across rapidly converging media
platforms and to take full advantage of the emergence of the Internet and the
ongoing digital revolution.
 
   In reaching the conclusion that the combination of Time Warner and America
Online is in the best interests of Time Warner and its stockholders, the board
of directors of Time Warner consulted with senior members of Time Warner's
management team regarding the strategic and operational aspects of the merger
and the results of the due diligence efforts undertaken by management. In
addition, the board of directors of Time Warner consulted with representatives
of Morgan Stanley, financial advisor to Time Warner, regarding selected
financial aspects of America Online's business and future prospects and
challenges facing Internet businesses in general and America Online in
particular, as well as the fairness, from a financial point of view, to Time
Warner's holders of common stock and series common stock of the proposed ratio
for exchanging shares of Time Warner common stock or series common stock for
shares of AOL Time Warner common stock or series common stock. The board of
directors of Time Warner also consulted with Time Warner's internal counsel and
with representatives of Cravath, Swaine & Moore, outside counsel to Time
Warner, regarding the duties of the members of the board of directors, legal
due diligence matters and the terms of the merger agreement and related
agreements. In considering the information provided by senior members of Time
Warner's management team, representatives of Morgan Stanley and representatives
of Cravath, Swaine & Moore, in analyzing the terms of the merger agreement, and
in coming to its endorsement of the merger, the board of directors of Time
Warner considered a variety of factors, a number of which are summarized below.
 
   Strategic Advantages. The board of directors of Time Warner reviewed
presentations from senior members of Time Warner's management team regarding
the strategic advantages of the combination of Time Warner and America Online.
The Time Warner board of directors considered management's view that the
combination of Time Warner's world-class media brands, subscriber bases and
technologically advanced broadband delivery systems with America Online's
renowned consumer online brands, subscriber base and extensive Internet
infrastructure and expertise will provide AOL Time Warner with strengths and
synergies in all its businesses. The Time Warner board considered management's
view that AOL Time Warner's multiple brands, vast array of content, extensive
infrastructure and strong distribution capabilities will provide it with a
greater capacity to capitalize on and propel the convergence of media,
entertainment and communications than Time Warner (or America Online) alone.
The Time Warner board of directors also considered the strategic benefits of
combining Time Warner's broadband infrastructure with America Online's
established success in managing consumer migration online. The Time Warner
board of directors also noted that this strategic combination would accelerate
the digital transformation of Time Warner by infusing all of Time Warner's
businesses with a heightened digital focus.
 
   Potential for Growth. The board of directors of Time Warner considered the
view of senior members of Time Warner's management team that the combination of
Time Warner and America Online is expected to strengthen the ability of these
companies to generate growth in revenue, earnings before interest, taxes and
amortization, or "EBITA," earnings before interest, taxes, depreciation and
amortization, or "EBITDA," and cash flow. In particular, the Time Warner board
of directors considered management's view that:
 
  .  America Online's extensive Internet infrastructure is expected to
     provide a new and expanding distribution medium for Time Warner's
     popular brands, thereby giving its content businesses increased access
     to the consumer; and
 
  .  Time Warner's advanced broadband delivery systems are expected to
     provide an important distribution platform for America Online's
     interactive services, which is expected to result in incremental
     subscriber growth.
 
   In addition, the Time Warner board noted management's view that:
 
  .  in the music business, AOL Time Warner will bring together Time Warner's
     prestigious labels and roster of established and new artists with
     America Online's established e-commerce capabilities, and
 
                                       35

<PAGE>
 
  .  in the publishing business, cross-marketing opportunities between Time
     Warner's prominent brands and America Online's interactive services are
     expected to provide new opportunities for subscriber growth.
 
   Finally, the Time Warner board considered management's view that AOL Time
Warner will have enhanced advertising and revenue potential due to its ability
to offer promotional packages that include both traditional and online
components.
 
   Strengthened International Position. The board of directors of Time Warner
considered the view of senior members of Time Warner's management team that the
combination of Time Warner's strong international presence with America
Online's global interactive services, will further strengthen the combined
company's position in the international marketplace.
 
   Increased Benefits for Consumers. The board of directors of Time Warner
reviewed the potential for the combination of Time Warner and America Online to
provide increased benefits for consumers. The Time Warner board of directors
considered the view of senior members of Time Warner's management team that,
through the combination of Time Warner's programming capabilities with America
Online's Internet capabilities, AOL Time Warner is expected to be able to
provide consumers with enhanced access to a broad selection of high quality
content and interactive services. The Time Warner board of directors also
considered management's view that, through the cooperative efforts of employees
with creative and journalistic talents and employees with technological
expertise, AOL Time Warner is expected to offer new and innovative products and
services that are particularly suited to interactive media.
 
   America Online's Business and Technology Infrastructure. In evaluating the
combination of Time Warner and America Online, the board of directors of Time
Warner considered information and analyses regarding the financial condition
and results of operations of America Online. The Time Warner board of directors
also considered information regarding America Online's Internet capacity and
capabilities. Finally, the Time Warner board of directors considered
information regarding prospects of and challenges facing Internet businesses in
general and America Online in particular, including the view that the future of
the Internet will be determined by companies that are able to take advantage of
the distribution channels created by the Internet through providing compelling
entertainment and informational content.
 
   Expected Impact of the Combination. The board of directors of Time Warner
noted that the combination of Time Warner and America Online is expected to
strengthen the financial condition of both Time Warner and America Online. The
Time Warner board of directors also noted that the combination of Time Warner
and America Online would be accounted for as a purchase transaction.
 
   Opinion of Morgan Stanley. The board of directors of Time Warner reviewed a
detailed presentation by representatives of Morgan Stanley regarding the
financial aspects of the proposed combination of Time Warner and America
Online, including the ratio of exchanging shares of Time Warner common stock
and series common stock for shares of AOL Time Warner common stock and series
common stock. The board of directors of Time Warner considered the opinion of
Morgan Stanley that the ratio for exchanging shares of Time Warner common stock
or series common stock for shares of AOL Time Warner common stock or series
common stock pursuant to the merger agreement was fair, from a financial point
of view, to the holders of common stock and series common stock of Time Warner.
 
   Ratio of Exchanging Shares of Time Warner Common Stock for Shares of AOL
Time Warner Common Stock. The board of directors of Time Warner considered the
fact that the proposed ratio of exchanging shares of common stock of Time
Warner for shares of common stock of AOL Time Warner would provide Time
Warner's stockholders with a substantial premium as compared to Time Warner's
and America Online's stock market prices at the time of execution of the merger
agreement.
 
   The board of directors of Time Warner considered the fact that the value of
the consideration to be received by holders of Time Warner's common stock could
change depending upon the performance of
 
                                       36

<PAGE>
 
America Online's common stock between the time of the execution of the merger
agreement and the time of the completion of the merger. The Time Warner board
of directors also considered the fact that the merger agreement does not
contain any provisions that limit the effect of declines in the market price of
common stock of America Online prior to the completion of the merger on the
value of the consideration to be received by holders of common stock of Time
Warner in the merger. The Time Warner board of directors considered the absence
of these provisions to be acceptable in the context of a "merger of equals" and
noted that, while the absence of these provisions exposes Time Warner
stockholders to some market risk, the risk is mitigated by the fact that
holders of Time Warner's common stock will participate in any appreciation in
the value of America Online's common stock between the time of the execution of
the merger agreement and the time of the completion of the merger and the fact
that any protection against declines in the market price of America Online's
common stock would likely be coupled with a cap on the benefit Time Warner's
stockholders would enjoy as a result of increases in the market price of
America Online's common stock.
 
   Continuing Equity Interest of Time Warner Stockholders in AOL Time
Warner. The board of directors of Time Warner considered the fact that, by
providing for the exchange of shares of common stock of Time Warner for shares
of common stock of AOL Time Warner, the merger agreement provides for holders
of Time Warner's common stock to participate in the value that may be generated
by the combination of Time Warner and America Online through their continued
equity participation in AOL Time Warner, while realizing through the exchange
of shares a premium (based on stock market prices at the time of execution of
the merger agreement) for their Time Warner shares and while obtaining tax-free
treatment. The Time Warner board of directors also noted that the proposed
ratio of exchanging shares of Time Warner common stock for shares of AOL Time
Warner common stock would result in holders of Time Warner's common stock
receiving a significant equity stake in AOL Time Warner, equal to approximately
45% of the outstanding common stock of AOL Time Warner after completion of the
merger.
 
   Corporate Governance Arrangements. The board of directors of Time Warner
noted that the merger agreement is structured as a "merger of equals" and
provides that the board of directors of AOL Time Warner will initially consist
of sixteen individuals, eight of whom will be designated by America Online and
eight of whom will be designated by Time Warner. In addition, the Time Warner
board of directors noted that the merger agreement provides that Stephen M.
Case, the Chairman of the Board and Chief Executive Officer of America Online,
will initially serve as Chairman of the Board of AOL Time Warner, and Gerald M.
Levin, the Chairman and Chief Executive Officer of Time Warner will initially
serve as Chief Executive Officer of AOL Time Warner. The Time Warner board of
directors also noted that the affirmative vote of 75% of the members of the
board of directors of AOL Time Warner will be required to change the size of
the board of directors and that, until December 31, 2003, the affirmative vote
of 75% of the members of the board of directors of AOL Time Warner will be
required to remove the chairman or chief executive officer. The Time Warner
board of directors concluded that these arrangements would reasonably assure
the continuity of the management of AOL Time Warner following completion of the
merger and allow a strong management team drawn from both Time Warner and
America Online to work together to integrate the two companies.
 
   Alternatives to the Merger. The board of directors of Time Warner considered
information presented by senior members of Time Warner's management team that,
in seeking a digital transformation of Time Warner, they had explored
alternatives to the proposed combination of Time Warner and America Online,
including the internal development of an Internet distribution infrastructure
and growth through acquisitions. The Time Warner board of directors also
considered the view of senior members of Time Warner's management team that the
combination of Time Warner with America Online provides Time Warner with an
extensive Internet distribution infrastructure in a relatively brief period of
time and cost-effective manner. In addition, the Time Warner board of directors
considered management's view that the combination of Time Warner and America
Online accelerates Time Warner's Internet distribution plan by several years
and provides significant cost savings with greater distribution capabilities,
opportunities for cross-marketing products and potential to offer consumers new
and innovative products than would other potential avenues for exploiting the
potential of the Internet.

   Integration of Time Warner and America Online. The board of directors of
Time Warner considered the fact that the combination of the businesses of Time
Warner and America Online would be challenging, and the success of the
combination is not certain. The Time Warner board of directors noted, however,
that the management teams of Time Warner and America Online have a shared
vision of the potential created by the combination of traditional and new
media. The Time Warner board of directors further noted that the businesses of
both Time Warner and America Online are based, in part, on the acquisition and
retention of subscribers. In addition, the Time Warner board of directors noted
that both management teams share a consumer and marketing focus, a new media
interactive service orientation and a sense of social commitment and
responsibility. The Time Warner board of directors then noted that these
similarities in experiences and views are likely to facilitate the efforts of
the management teams of Time Warner and America Online to integrate their
businesses effectively and efficiently.
 
   Conditions, Termination Provisions, Termination Fee. The board of directors
of Time Warner reviewed the conditions to the completion of the merger and the
circumstances under which Time Warner or America Online would have the right to
terminate the merger agreement. In addition, the Time Warner board of directors
reviewed the provisions of the merger agreement that prohibit each of Time
Warner and America Online from soliciting any proposal or offer regarding any
acquisition of Time Warner or America Online, as the case may be. The board of
directors of Time Warner also reviewed the provisions of the merger agreement
that require the board of directors of each of Time Warner and America Online
to recommend adoption of the merger agreement by the stockholders of Time
Warner or America Online, as the case may be, and prohibit the board of
directors of each of Time Warner and America Online from withdrawing or
modifying its recommendation unless, subject to specified conditions, it has
received an unsolicited acquisition proposal which would, if completed, result
in a transaction that is more favorable to its stockholders than the merger and
which is reasonably capable of being completed. The Time Warner board of
directors also reviewed the various amounts that might be payable in the event
the merger agreement is terminated under specified circumstances. The Time
Warner board of directors noted that while these provisions could have an
impact on a third party considering an unsolicited acquisition proposal for
Time Warner, the provisions were reasonably necessary to protect both Time
Warner's and America Online's interests in the context of the proposed merger.
In addition, the Time Warner board of directors found reasonable the views of
its legal and financial advisors that the fees were within the range of fees
payable in comparable transactions and would not be expected to preclude an
unsolicited acquisition proposal for Time Warner.
 
   Option Agreements and Voting Agreement. The board of directors of Time
Warner also considered the terms of the option agreements to be entered into by
Time Warner and America Online in connection with the merger agreement and
their potential impact on a third party considering an unsolicited acquisition
proposal for Time Warner. The Time Warner board of directors noted that America
Online had specified that an agreement to enter into the option agreements was
a condition to entering into the merger agreement. The Time Warner board of
directors also noted that the option agreements would have largely an
accounting impact on the structure of an unsolicited acquisition proposal for
Time Warner, and it found reasonable the views of its legal and financial
advisors that the agreements would not be expected to preclude an unsolicited
acquisition proposal for Time Warner. In addition, the Time Warner board of
directors considered the terms of the voting agreement to be entered into by
Mr. Turner in connection with the merger agreement. The Time Warner board of
directors noted that, under the voting agreement, Mr. Turner would agree to
vote substantially all of his shares of common stock of Time Warner,
representing approximately 9% of the outstanding shares, in favor of adoption
of the merger agreement.
 
   Regulatory Matters. In addition to considering the various conditions that
must be satisfied prior to the completion of the merger, the board of directors
of Time Warner specifically considered the various regulatory filings and
approvals that would be necessary to complete the merger, including filings
with the Antitrust Division of the Department of Justice and Federal Trade
Commission, the approval of the Federal Communications Commission and the
approval of numerous state and local authorities and foreign regulators. The
Time Warner board of directors noted the view of members of senior management
of Time Warner that the
 
                                       38

<PAGE>
 
various regulatory filings were expected to be timely made and that the various
regulatory approvals were expected to be granted in due course.
 
   This summary of the factors considered by the board of directors of Time
Warner in evaluating the merits of the combination of Time Warner and America
Online is not intended to be exhaustive but is believed to include all material
factors considered by the Time Warner board of directors. Due to the wide
variety of the factors that the Time Warner board of directors considered in
evaluating the merits of the combination of Time Warner and America Online, the
Time Warner board of directors did not find it practicable to, and did not
attempt to, quantify or otherwise assign relative weights to the specific
factors considered in its evaluation. In addition, the Time Warner board of
directors did not undertake to make any specific determination as to whether
any particular factor, or any aspect of any particular factor, should be
regarded as favorable or unfavorable; instead the Time Warner board of
directors analyzed all of the factors as a whole and determined that, overall,
the factors support its conclusion that the combination of Time Warner and
America Online is in the best interests of Time Warner and its stockholders.
Individual members of the Time Warner board of directors may have considered
some factors to be more important than other factors and may have considered
some factors, or aspects of some factors, to be favorable while other members
considered them to be unfavorable.
 
Recommendation of America Online's Board Of Directors
 
   The America Online board of directors believes that the merger is fair to
America Online's stockholders and in their best interest, and recommends the
adoption of the merger agreement.
 
   In considering the recommendation of the America Online board of directors
with respect to the merger agreement, you should be aware that certain
directors and executive officers of America Online have interests in the merger
that are different from, or are in addition to, the interests of America Online
stockholders. Please see the section entitled "Interests of Certain America
Online Directors and Executive Officers in the Merger" that begins on page 54
of this joint proxy statement-prospectus.
 
Opinion of America Online's Financial Advisor
 
   America Online retained Salomon Smith Barney to act as its financial advisor
in connection with a possible business combination transaction with Time
Warner. In connection with its engagement, America Online instructed Salomon
Smith Barney to evaluate the fairness, from a financial point of view, of the
Time Warner common stock exchange ratio to America Online. At the January 9,
2000 meeting of the board of directors of America Online, Salomon Smith Barney
delivered its written opinion to the board of directors of America Online to
the effect that, as of the date of such opinion and based upon the various
qualifications and assumptions set forth therein, the exchange ratio of 1.5
shares of AOL Time Warner common stock for each share of Time Warner common
stock is fair, from a financial point of view, to America Online.
 
   The full text of Salomon Smith Barney's opinion dated January 9, 2000 is
attached as Annex E to this joint proxy statement-prospectus. We urge you to
read this opinion in its entirety for assumptions made, procedures followed,
matters considered and limits of the review by Salomon Smith Barney in arriving
at its opinion. The summary of the opinion of Salomon Smith Barney is qualified
in its entirety by reference to the full text of Salomon Smith Barney's
opinion.
 
   Salomon Smith Barney's opinion is directed only to the fairness, from a
financial point of view, of the Time Warner common stock exchange ratio to
America Online and is not intended and does not constitute a recommendation to
any stockholder of America Online as to how such stockholder should vote at the
America Online special meeting. No limitations were imposed by America Online
upon Salomon Smith Barney with respect to the investigations made or procedures
followed by it in rendering its opinion. Although Salomon Smith Barney
evaluated the financial terms of the merger and participated in discussions
concerning the determination of the Time Warner common stock exchange ratio,
Salomon Smith Barney was not asked to and
 
                                       39

<PAGE>
 
did not recommend this exchange ratio, which was the result of arm's length
negotiations between America Online and Time Warner.
 
   In connection with rendering its opinion, Salomon Smith Barney, among other
things:
 
  .  reviewed a draft of the merger agreement;
 
  .  held discussions separately with certain senior officers and other
     representatives and advisors of America Online and Time Warner
     concerning the business, operations and prospects of America Online and
     Time Warner, respectively;
 
  .  examined publicly available business and financial information relating
     to America Online and Time Warner as well as certain estimates and other
     data for America Online and Time Warner prepared by Salomon Smith
     Barney's and Morgan Stanley's research analysts;
 
  .  examined information relating to some of the strategic implications and
     operational benefits anticipated from the merger; and
 
  .  evaluated the potential pro forma financial impact of the merger on
     America Online.
 
   In addition, Salomon Smith Barney conducted other analyses and examinations
and considered other financial, economic and market criteria as it deemed
appropriate.
 
   In rendering its opinion, Salomon Smith Barney assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information publicly available or furnished to or otherwise reviewed
by or discussed with it. Salomon Smith Barney relied on estimates prepared by
Salomon Smith Barney's research analysts, based on Salomon Smith Barney's own
independent evaluation of this information and indications by the management of
America Online that the estimates regarding America Online were reasonably
consistent with their own and indications by the management of Time Warner that
estimates regarding Time Warner prepared by Morgan Stanley's research analysts
were reasonably consistent with their own. Salomon Smith Barney determined that
its research analysts' estimates regarding Time Warner were generally
consistent with Morgan Stanley's research analysts' estimates regarding Time
Warner, which was acknowledged by the managements of America Online and Time
Warner. With respect to the anticipated strategic, financial and operational
benefits of the merger, Salomon Smith Barney assumed that the information
provided was reasonably prepared on bases reflecting the best currently
available estimates and judgments as to the strategic implications and
operational benefits anticipated to result from the merger. Salomon Smith
Barney assumed that the merger agreement would be substantially the same as the
draft which Salomon Smith Barney reviewed. Salomon Smith Barney further
assumed, with the consent of America Online, that the merger will be treated as
a tax-free "reorganization" for federal income tax purposes.
 
   Salomon Smith Barney did not express any opinion as to what the value of AOL
Time Warner common stock actually will be when issued pursuant to the merger or
the price at which the AOL Time Warner common stock will trade subsequent to
the merger. Salomon Smith Barney did not make and was not provided with an
independent evaluation or appraisal of the assets or liabilities (contingent or
otherwise) of America Online or Time Warner nor did Salomon Smith Barney make
any physical inspection of the properties or assets of America Online or Time
Warner. Salomon Smith Barney was not requested to consider, and Salomon Smith
Barney's opinion does not address, the relative merits of the merger as
compared to any alternative business strategies that might exist for America
Online or the effect of any other transaction in which America Online might
engage.
 
   Salomon Smith Barney's opinion was necessarily based on the information made
available to it, and financial, stock market and other conditions and
circumstances existing and disclosed to Salomon Smith Barney as of the date of
its opinion.
 
   In preparing its opinion, Salomon Smith Barney performed a variety of
financial and comparative analyses. The following is a summary of the material
financial analyses performed by Salomon Smith Barney
 
                                       40

<PAGE>
 
in connection with the preparation of its opinion. These analyses were
presented to the board of directors of America Online at its meeting on January
9, 2000. The following summary of the material financial analyses contains
information in tabular format. In order fully to understand the financial
analyses used by Salomon Smith Barney, the tables must be read in conjunction
with the text of each summary. The tables alone do not constitute a complete
description of the financial analyses.
 
   Historical Stock Price Performance. Salomon Smith Barney reviewed the
relationship between movements of the America Online common stock, the Time
Warner common stock and the Standard & Poor's 400 Composite Index for the
period from and including January 7, 1999 through January 7, 2000, the average
closing prices for the Time Warner common stock and the America Online common
stock over various periods during the 3-year period ended January 7, 2000 and
the trading volume and price history of the America Outline common stock and
the Time Warner common stock for the period from and including January 7, 1999
through January 7, 2000.
 
   Implied Historical Exchange Ratio Analysis. Salomon Smith Barney reviewed
the implied historical exchange ratio between the America Online common stock
and the Time Warner common stock determined by dividing the average and the
volume weighted average, respectively, prices per share of Time Warner common
stock by the average and the volume weighted average, respectively, prices per
share of America Online Common Stock over various periods during the three-year
period ended January 7, 2000. This review indicated the following implied
historical exchange ratios:

   Implied Exchange Ratio Analysis. Salomon Smith Barney derived a range of
values for Time Warner and America Online by utilizing a sum-of-the-parts
valuation analysis which separately values distinct assets and businesses of a
company by applying various valuation methodologies to those assets and
businesses and uses the derived valuations to arrive at a range of values for
the consolidated entity. Salomon Smith Barney then used the derived valuation
ranges to determine the implied exchange ratios. The following are the three
principal valuation methodologies used by Salomon Smith Barney in this
analysis:
 
  .  Public Market Valuation Analysis. A public market analysis reviews a
     business' operating performance and outlook relative to a group of
     publicly traded peer companies to determine an implied unaffected market
     trading valuation range.
 
  .  Private Market Valuation Analysis. A private market analysis provides a
     valuation range based upon financial information of companies involved
     in selected recent business combination transactions or in business
     combination transactions that have been publicly announced and which are
     in the same or similar industries as the business being valued.
 
  .  Discounted Cash Flow Analysis. A discounted cash flow analysis derives
     the intrinsic value of a business based on the net present value of the
     future free cash flow anticipated to be generated by the assets of the
     business.
 
   Salomon Smith Barney considered the values derived for various Time Warner
businesses from the public and private market valuations and the discounted
cash flow analyses under two scenarios. In the "100% Synergies" scenario,
Salomon Smith Barney included merger-related revenue enhancements and cost
savings (commonly referred to as "synergies") provided by the management of
America Online as well as tax savings
 
                                       41

<PAGE>
 
estimated to be achieved through the application by the combined company of
existing and expected net operating losses of America Online over five years.
The synergies were discussed with America Online and Time Warner managements,
although Time Warner did not participate in the quantification of the
synergies. In the "No Synergies" scenario, Salomon Smith Barney did not give
effect to any synergies or to any tax savings that may be achieved from the
application of the net operating losses. Salomon Smith Barney considered the
values derived for various America Online businesses from public market
valuations and discounted cash flow analyses. Salomon Smith Barney used the
values calculated in its analyses to derive a range of implied exchange ratios
for each valuation methodology. These implied exchange ratios are set forth in
the table below.

   The low implied exchange ratios in these ranges were determined by dividing
the low Time Warner share value that had been calculated using the indicated
valuation methodology by the high America Online share value that had been
calculated using the indicated valuation methodology. Similarly, the high
implied exchange ratios in these ranges were determined by dividing the high
Time Warner share value that had been calculated using the indicated valuation
methodology range by the low America Online share value that had been
calculated using the indicated valuation methodology.
 
 Time Warner Valuation
 
   Salomon Smith Barney derived a valuation for Time Warner by performing
financial analysis with respect to the following consolidated and non-
consolidated assets and businesses of Time Warner:
 
  .  cable systems business;
 
  .  cable networks business;
 
  .  filmed entertainment business;

   Minority Interest. Part of Time Warner's cable, cable networks and filmed
entertainment businesses is held by TWE. In connection with deriving the public
and private market and discounted cash flow valuations of Time Warner's
interest in TWE, Salomon Smith Barney excluded the equity values in TWE of the
other partners of TWE. Salomon Smith Barney derived an implied value for TWE
using the same sum-of-the parts valuation methodology as for Time Warner but
applied a 20% minority discount to reflect the other partners' minority
interests.
 
   Public Market Analysis of Time Warner. Salomon Smith Barney reviewed and
compared various actual and forecasted financial, operating and stock market
information of the individual Time Warner businesses listed below (collectively
referred to as the "Time Warner businesses" and, together with the WB network
business, the "Time Warner consolidated businesses") with that of various
publicly traded companies in corresponding industries, which companies Salomon
Smith Barney believed are comparable in relevant respects to the applicable
Time Warner business:
 
  .  cable systems;
 
  .  cable networks;
 
  .  filmed entertainment;
 
  .  publishing; and
 
  .  music.
 
   Salomon Smith Barney calculated various financial multiples for each of the
Time Warner businesses and for each of the applicable groups of comparable
companies including, in certain cases, firm value to historical EBITDA and to
estimated 2001 EBITDA. Salomon Smith Barney then calculated, among other
things, a range of estimated 2001 EBITDA multiples, as summarized in the table
below. Salomon Smith Barney utilized the multiples of the applicable comparable
companies for purposes of calculating the implied value of the Time Warner
businesses. The multiple ranges for the comparable companies that Salomon Smith
Barney deemed relevant to this analysis are summarized below.

Accordingly, an examination of the results of the comparable companies used in
this analysis necessarily involved complex considerations of the businesses and
judgments concerning differences in financial and operating characteristics and
other factors that could affect the public trading values or the acquisition
values of these companies. In addition, Salomon Smith Barney performed its

   Private Market Valuation Analysis of Time Warner. Salomon Smith Barney
reviewed and analyzed certain financial, operating and stock market information
relating to comparable selected transactions in the cable systems, cable
networks, diversified media, filmed entertainment, publishing and music
industries. To the extent that the relevant information was publicly available,
Salomon Smith Barney calculated the multiples of firm value to estimated 2001
EBITDA represented by the transaction prices of the subject companies in the
cable systems industry and the multiples of firm value to last twelve month
revenue and firm value to last

twelve month EBITDA represented by the transaction prices of the subject
companies in the other industries described below. Using this information and
other factors relevant in the valuation of the Time Warner businesses, Salomon
Smith Barney determined an estimated 2001 EBITDA multiple range for each of the
Time Warner businesses and calculated an implied value of the Time Warner
businesses utilizing those multiples. The multiple ranges for the selected
transactions that Salomon Smith Barney deemed relevant to this analysis are
summarized below.

   No transaction used in the private market valuation analysis described above
is identical to the merger and none of the constituent companies are identical
to the respective Time Warner business being analyzed. Accordingly, any
analysis of the selected comparison transactions necessarily involved complex
considerations and judgments concerning differences in financial and operating
characteristics and other factors that would necessarily affect the value of
the given Time Warner business versus the values of the transactions to which
that business was being compared.
 
   WB Network. Salomon Smith Barney calculated the implied firm value of
approximately $1.0 billion for the WB Network using published analyst reports.
This implied firm value was included by Salomon Smith Barney in its public and
private market valuations which derived the aggregate implied firm value of
Time Warner.
 
   Discounted Cash Flow Analysis. Salomon Smith Barney performed a discounted
cash flow analysis of the various Time Warner consolidated businesses to
estimate ranges of intrinsic values for each of the Time Warner consolidated
businesses. Salomon Smith Barney applied a terminal value multiple ranges to
the forecasted EBITDA in calendar 2004 for each of the Time Warner consolidated
businesses. The ranges of terminal value multiples used for each of the Time
Warner consolidated businesses are set forth in the table below. The unlevered
free cash flows of each of the Time Warner consolidated businesses were then
discounted to present value using various discount rates. The ranges of
discount rates and multiples used for each of the Time Warner consolidated
businesses are set forth in the table below.

   Time Warner Non-Consolidated Assets. Salomon Smith Barney reviewed and
compared various actual and forecasted financial, operating and stock market
information, as applicable, with respect to Time Warner's non-consolidated
investments identified below. For Time Warner's investments in publicly traded
companies, such as Primestar and Time Warner Telecom, Salomon Smith Barney
derived the implied firm value using the current market trading prices of those
companies' securities. With respect to other non-consolidated investments,
including the unconsolidated cable and Road Runner joint ventures, Salomon
Smith Barney performed applicable analyses using subscriber multiples and other
subscriber information to derive an implied
 
                                       44

<PAGE>
 
firm value. For the remaining non-consolidated investments, Salomon Smith
Barney calculated the implied firm value using forecasted EBITDA and published
analyst reports.
 
   The aggregate implied firm value for Time Warner's non-consolidated
investments was included by Salomon Smith Barney in its public and private
market valuations and its discounted cash flow analyses in order to derive the
aggregate implied firm value ranges for Time Warner.
 
   Net Operating Losses. Based on management estimates of aggregate existing
and expected net operating losses of the combined company, assuming that these
net operating losses could be used without limitation through fiscal 2005, and
based upon a 35% federal tax rate and an 11% discount rate, Salomon Smith
Barney derived an implied present value of approximately $1.5 billion for the
tax savings estimated to be achieved from these net operating losses.
 
   Synergies. Salomon Smith Barney considered the value of the net synergies
related to the merger provided by the management of America Online. The
synergies were discussed with America Online and Time Warner managements,
although Time Warner did not participate in the quantification of the
synergies. The net synergies are estimated to increase EBITDA by $1 billion in
fiscal 2001. The estimates of synergies are based on numerous estimates,
assumptions and judgments and are subject to significant uncertainties. In
addition, the actual synergies realized in the merger may vary materially from
the estimates used in Salomon Smith Barney's analysis.
 
 America Online Valuation
 
   Public Market Analysis of America Online. Salomon Smith Barney reviewed and
compared various actual and forecasted financial, operating and stock market
information of the individual America Online businesses listed below
(collectively referred to as the "America Online businesses") with that of
various publicly traded companies in corresponding industries, which companies
Salomon Smith Barney believed are comparable in relevant respects to the
applicable America Online business:
 
  .  internet access;
 
  .  online portals (advertising/e-commerce); and
 
  .  enterprise solutions.
 
   Salomon Smith Barney calculated various financial multiples for the America
Online businesses and for each of the applicable groups of comparable companies
including firm value to historical revenues and to estimated forward revenues.
Salomon Smith Barney then calculated, among other things, a range of estimated
Year 2000 revenue multiples, as summarized in the table below. For purposes of
calculating the implied value of the America Online businesses, Salomon Smith
Barney utilized these multiples. The multiple ranges for the comparable
companies that Salomon Smith Barney deemed relevant to this analysis are
summarized below.

   Discounted Cash Flow Analysis. Salomon Smith Barney performed a discounted
cash flow analysis of America Online to estimate a range of intrinsic values of
America Online. Salomon Smith Barney applied a terminal value multiple range of
40.0x to 80.0x to America Online's forecasted EBITDA for calendar 2004. The
unlevered free cash flows were then discounted to present value using various
discount rates ranging from of 14.0% to 16.0%.
 
   Contribution Analysis. Salomon Smith Barney performed an exchange ratio
analysis comparing the relative contributions of Time Warner and America Online
to the combined company. The following table displays each company's relative
contribution to the combined company's actual 1998 and estimated 1999, 2000 and
2001 revenues, EBITDA and net income, as well as the combined company's market

   Pro Forma Earnings Per Share Impact to America Online. Salomon Smith Barney
reviewed certain pro forma financial effects of the merger on the estimated
earnings per share of America Online common stock. Using First Call estimates,
Salomon Smith Barney compared the earnings per share of America Online common
stock, on a stand-alone basis assuming the merger was not consummated to the
estimated earnings per share of America Online common stock following
consummation of the merger on a pro forma basis. Salomon Smith Barney's
analysis gave effect to the issuance of shares of AOL Time Warner common stock
to America Online and Time Warner stockholders pursuant to the merger agreement
and gave effect to the net estimated synergies. Based on such analysis, Salomon
Smith Barney determined that the merger would be: (a) dilutive to, or result in
a decrease in, the earnings per share of America Online common stock on a pro
forma basis by approximately 404.7% in calendar 2000 and approximately 267.0%
in calendar 2001 using First Call GAAP earnings per share estimates and (b)
accretive to, or result in an increase in, the earnings per share of America
Online common stock on a pro forma basis by approximately 63.6% in calendar
2000 and approximately 48.5% in calendar 2001 using cash earnings per share
estimates which are based on the First Call GAAP earnings per share estimates
and adding goodwill amortization per share.

   Other Analyses. Salomon Smith Barney conducted such other analyses as it
deemed necessary, including reviewing selected investment research reports on,
and earnings estimates for, America Online and Time Warner.

the merger because of its experience and expertise and its familiarity with
America Online. As part of its investment banking business, Salomon Smith
Barney is regularly engaged in the valuation of businesses and their securities
in connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted

   Pursuant to the terms of an engagement letter dated January 9, 2000, America
Online agreed to pay Salomon Smith Barney financial advisory fees.
Additionally, America Online has agreed to reimburse Salomon Smith Barney for
reasonable out-of-pocket expenses incurred by Salomon Smith Barney in
performing its services, including the fees and expenses of its legal counsel,

America Online unrelated to the merger, for which services Salomon Smith Barney
has received compensation. In addition, Salomon Smith Barney and its affiliates
(including Citigroup Inc. and its affiliates) may maintain relationships with
America Online or Time Warner.
 
Recommendation of Time Warner's Board of Directors
 
   The Time Warner board of directors believes that the merger is fair to Time
Warner's stockholders and in their best interest, and recommends the adoption
of the merger agreement.
 
   In considering the recommendation of the Time Warner board of directors with
respect to the merger agreement, you should be aware that certain directors and
executive officers of Time Warner have interests in the merger that are
different from, or are in addition to, the interests of Time Warner
stockholders. Please see the section entitled "Interests of Certain Time Warner
Directors and Executive Officers in the Merger" that begins on page 55 of this
joint proxy statement-prospectus.
 
Opinion of Time Warner's Financial Advisor
 
   Time Warner retained Morgan Stanley to provide it with financial advisory
services and a financial fairness opinion in connection with the merger. The
Time Warner board of directors selected Morgan Stanley to act as Time Warner's
financial advisor based on Morgan Stanley's qualifications, expertise and
reputation and its knowledge of the business and affairs of Time Warner. At the
meeting of the Time Warner board on January 9, 2000, Morgan Stanley rendered
its oral opinion, subsequently confirmed in writing, that as of January 9,
2000, and subject to and based on the considerations in its opinion, the
exchange ratio pursuant to the merger agreement is fair from a financial point
of view to the holders of Time Warner common stock and series common stock.
 
   The full text of Morgan Stanley's opinion, dated as of January 9, 2000,
which sets forth, among other things, the assumptions made, procedures
followed, matters considered and limitations on the review undertaken by Morgan
Stanley is attached as Annex F to this joint proxy statement-prospectus. We
urge you to read this opinion carefully and in its entirety. Morgan Stanley's
opinion is directed to the
 
                                       47

<PAGE>
 
board of directors of Time Warner, addresses only the fairness from a financial
point of view of the exchange ratio pursuant to the merger agreement to the
holders of Time Warner common stock and series common stock, and does not
address any other aspect of the merger or constitute a recommendation to any
Time Warner stockholder as to how to vote at the special meeting. This summary
is qualified in its entirety by reference to the full text of the opinion.
 
   In connection with rendering its opinion, Morgan Stanley, among other
things:
 
  .  reviewed certain publicly available financial statements and other
     information of America Online and Time Warner;
 
  .  discussed the past and current operations and financial condition and
     the prospects of America Online and Time Warner with senior executives
     of America Online and Time Warner, respectively;
 
  .  discussed with senior executives of America Online and Time Warner
     certain strategic, financial and operational benefits they anticipate
     from the merger;
 
  .  reviewed the reported prices and trading activity for America Online's
     common stock and Time Warner's common stock;
 
  .  compared the financial performance of America Online and Time Warner and
     the prices and trading activity of America Online's common stock and
     Time Warner's common stock with those of other comparable publicly
     traded companies and their securities;
 
  .  reviewed the financial terms, to the extent publicly available, of
     precedent transactions that Morgan Stanley deemed relevant;
 
  .  participated in discussions and negotiations among representatives of
     America Online and Time Warner and their financial and legal advisors;
 
  .  reviewed the draft of the merger agreement, the draft of the voting
     agreement to be entered into between America Online and Mr. Turner and
     his affiliates and the draft of the stock option agreements to be
     entered into between America Online and Time Warner, each substantially
     in the form of the draft dated January 9, 2000, and related documents;
     and
 
  .  performed other analyses and considered other factors as Morgan Stanley
     deemed appropriate.
 
   Morgan Stanley assumed and relied upon, without independent verification,
the accuracy and completeness of the information reviewed by it for the
purposes of its opinion. Morgan Stanley did not receive financial forecasts for
America Online or Time Warner and instead relied on the publicly available
estimates of selected analysts, including those at Morgan Stanley, who report
on America Online and Time Warner. With respect to the anticipated strategic,
financial and operational benefits of the merger, including assumptions
regarding America Online's and Time Warner's existing and future products and
technologies, Morgan Stanley assumed that the information provided has been
reasonably prepared on the bases reflecting the best currently available
estimates and judgments of the future financial and operational performance of
America Online and Time Warner. Morgan Stanley did not make and did not assume
responsibility for making any independent valuation or appraisal of the assets
or liabilities of Time Warner or America Online, nor was Morgan Stanley
furnished with any appraisals of those assets and liabilities. Morgan Stanley
assumed that the executed versions of the merger agreement, the voting
agreement and the stock option agreements would not differ in any material
respect from the last drafts of these agreements reviewed by Morgan Stanley.
Morgan Stanley assumed that the merger will be completed in accordance with the
terms provided in the merger agreement without material modification or waiver
and that the merger will be a tax-free reorganization or exchange under the
Internal Revenue Code of 1986. The opinion of Morgan Stanley is necessarily
based on financial, economic, market and other conditions as in effect on, the

   Morgan Stanley then compared the price performance of the Time Warner common
stock from January 7, 1999 through January 7, 2000 with that of the S&P 500
Index and of a group of selected media and entertainment companies and the
price performance of the America Online common stock over the same period with
that of the Nasdaq Composite Index and of a group of selected Internet
companies.
 
   The group of selected media and entertainment companies included CBS
Corporation, Comcast Corporation, Viacom, Inc., News Corp. Ltd., Cablevision
Systems Corporation, Cox Communications Inc., The Seagram Company Ltd., The
Walt Disney Company and Fox Corporation. The group of selected Internet
companies included CNET, Inc., Yahoo! Inc., Lycos, Inc., eBay Inc., Excite,
Inc. and Amazon.com, Inc. Morgan Stanley selected CNET, Excite, Lycos and
Yahoo! because they are publicly traded companies with Internet portal
operations that, for purposes of this analysis, may be considered similar to
those of America Online. Morgan Stanley also selected Amazon.com and eBay
because they are publicly traded companies that are leaders in e-commerce
retail and because their leading positions in this market may be considered,
for purposes of this analysis, similar to America Online. None of the companies
utilized in this analysis as a comparison is identical to Time Warner or
America Online.
 
   This analysis showed that the closing market prices during the period from
January 7, 1999 through January 7, 2000 appreciated as follows:

estimates. Morgan Stanley then compared the EBITDA multiples obtained for Time
Warner with multiples obtained for a group of selected media and entertainment
companies. Morgan Stanley calculated aggregate value to revenue multiples for
America Online for fiscal years 1999 through 2001 based on publicly available
Morgan Stanley research estimates. Morgan Stanley then compared the revenue
multiples obtained for America Online with multiples obtained for a group of
selected Internet companies.
 
   The group of selected media and entertainment companies included Cablevision
Systems Corporation, The Walt Disney Company, Fox Corporation, News Corp. Ltd.,
The Seagram Company Ltd. and the combined Viacom/CBS Corporation entity. Morgan
Stanley selected these companies because they are publicly traded companies
with media and entertainment operations that for purposes of this analysis may
be considered similar to those of Time Warner.
 
   The group of selected Internet companies included Excite, Inc., Lycos, Inc.,
Yahoo! Inc., Amazon.com, Inc. and eBay Inc. Morgan Stanley selected Excite,
Lycos and Yahoo! because they are publicly traded companies with Internet
portal operations that, for purposes of this analysis, may be considered
similar to those of America Online. Morgan Stanley also selected Amazon.com and
eBay because they are publicly traded leaders in e-commerce retail which,
because of their leading positions in this market, may be considered for
purposes of this analysis similar to America Online.

   Securities Research Analysts' Future Price Targets Analysis.  Morgan Stanley
reviewed the 12-month price targets for the shares of common stock of each of
Time Warner and America Online as projected by analysts from various financial
institutions in recent reports. These targets reflected each analyst's estimate
of the future public market trading price of Time Warner common stock and
America Online common stock at the end of the particular period considered for
each estimate. Morgan Stanley then arrived at the present value for these
targets using an estimated equity discount rate of 12.7% for the Time Warner
common stock and 18.5% for the America Online common stock.

   Morgan Stanley noted that the exchange ratio pursuant to the merger
agreement implied a value of $110.625 for the common stock of Time Warner
resulting from the merger, based on the trading price of the America Online
common stock on January 7, 2000.
 
   Historical Exchange Ratio Analysis.  Morgan Stanley reviewed the implied
historical exchange ratios for the shares of common stock of each of Time
Warner and America Online determined by dividing the price per share of Time
Warner common stock by the price per share of America Online common stock over
the three-year period from January 7, 1997 through January 7, 2000, and over
the twelve-month period from January 7, 1999 through January 7, 2000. Morgan
Stanley performed this analysis to compare the premium represented by the
exchange ratio in the merger with the premium/(discount) represented by
historical exchange ratios prevailing in the open market.
 
   This analysis indicated the following premiums/(discounts) represented by
the average historical exchange ratios prevailing in the open market:

   Morgan Stanley noted that the 1.5x exchange ratio in the merger agreement
implied a 71% premium to the market ratio implied by the trading prices of the
America Online and Time Warner common stock on January 7, 2000.
 
   Relative Contribution Analysis.  Morgan Stanley compared pro forma
contribution of each of Time Warner and America Online, based on publicly
available Morgan Stanley research estimates, to the resultant combined company
assuming completion of the merger. Morgan Stanley adjusted these statistics to
reflect each company's respective capital structures and then compared them to
the pro forma ownership by Time Warner stockholders of the common stock of the
combined company of approximately 45%, implied by the exchange ratio.

   Pro Forma Merger Analysis.  Morgan Stanley analyzed the pro forma effect of
the merger on each of Time Warner's and America Online's actual and projected
revenue and EBITDA for fiscal 1998 to fiscal 2001, based on publicly available
Morgan Stanley research estimates, compared to the revenue and EBITDA growth
rates of Time Warner and America Online on a standalone basis in each of the

   Premiums Paid in Selected Precedent Transactions Analysis.  Morgan Stanley
reviewed nine recent selected business combinations structured as mergers of
equals and analyzed the premiums/discounts paid in these transactions over
prevailing market prices before the announcement of these transactions. Morgan
Stanley selected these transactions because they were structured as mergers of
equals of large publicly-traded corporations and not because they involved
companies engaged in industries that would be similar or related to those in
which Time Warner or America Online operate.
 
   These transactions are: the Viacom, Inc./CBS Corporation transaction, the
Vodafone PLC/AirTouch Communications, Inc. transaction, the British Petroleum
Company/Amoco Corporation transaction, the Bell Atlantic Corporation/GTE
Corporation transaction, the Norwest Corporation/Wells Fargo & Company
transaction, the SBC Communications Inc./Ameritech Corporation transaction, the
Daimler-Benz Aktiengesellschaft/Chrysler Corporation transaction, the
NationsBank Corporation/Bank of America Corporation transaction and the
Travelers Group Inc./Citicorp transaction.

   No company or transaction utilized in the peer group comparison analysis is
identical to Time Warner or America Online or the merger. In evaluating the
peer groups, Morgan Stanley made judgments and assumptions with regard to
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Time
Warner or America Online, such as the impact of competition on the business of
Time Warner, America Online, or the industry generally, industry growth and the
absence of any adverse material change in the financial condition and prospects
of Time Warner, America Online or the industry or in the financial markets in
general, which could affect the public trading value of the companies and the
aggregate value of the transactions to which they are being compared.
Mathematical analysis, such as determining the mean or median, or the high or
the low, is not in itself a meaningful method of using peer group data.
 
   In connection with the review of the merger by Time Warner's board of
directors, Morgan Stanley performed a variety of financial and comparative
analyses for purposes of rendering its opinion. The preparation of a fairness
opinion is a complex process and is not necessarily susceptible to a partial
analysis or summary description. In arriving at its opinion, Morgan Stanley
considered the results of all of its analyses as a whole and did not attribute
any particular weight to any analysis or factor considered by it. Morgan
Stanley believes that the summary provided and the analyses described above
must be considered as a whole and that selecting portions of these analyses,
without considering all of them, would create an incomplete view of the process
underlying its analyses and opinion. In addition, Morgan Stanley may have given
various analyses and factors more or less weight than other analyses and
factors and may have deemed various assumptions more or less probable than
other assumptions, so that the range of valuations resulting from any
particular analysis described above should therefore not be taken to be Morgan
Stanley's view of the actual value of Time Warner or America Online.
 
   In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Time Warner or America
Online. Any estimates contained in Morgan Stanley's analysis are not
necessarily indicative of future results or actual values, which may be
significantly more or less favorable than those suggested by these estimates.
The analyses performed were prepared solely as a part of Morgan Stanley's
analysis of the fairness from a financial point of view to the holders of
common stock and series common stock of Time Warner of the exchange ratio
pursuant to the merger agreement and were conducted in connection with the
delivery by Morgan Stanley of its opinion dated January 9, 2000 to the board of
directors of Time Warner. Morgan Stanley's analyses do not purport to be
appraisals or to reflect the prices at which shares of common stock or series
common stock of Time Warner or America Online might actually trade. The
exchange ratio in the merger was determined through arm's length negotiations
between Time Warner and America Online and was approved by Time Warner's board
of directors. Morgan Stanley did not recommend any specific exchange ratio to
Time Warner or that any given exchange ratio constituted the only appropriate
exchange ratio for the merger.
 
   Morgan Stanley is an internationally recognized investment banking and
advisory firm. Morgan Stanley, as part of its investment banking and financial
advisory business, is continuously engaged in the valuation of businesses and
their securities in connection with mergers and acquisitions, negotiated
underwritings,

competitive biddings, secondary distributions of listed and unlisted
securities, private placements and valuations for corporate and other purposes.
In the past, Morgan Stanley and its affiliates have provided financial advisory
and financing services for Time Warner and America Online and have received
fees for the rendering of these services. In the ordinary course of business,
Morgan Stanley may from time to time trade in the securities or indebtedness of
Time Warner and America Online for its own account, the accounts of investment
funds and other clients under the management of Morgan Stanley and for the
accounts of its customers and, accordingly, may at any time hold a long or
short position in these securities or indebtedness.
 
   Time Warner has agreed to pay transaction fees to Morgan Stanley. Time
Warner has also agreed to reimburse Morgan Stanley for its expenses incurred in
performing its services and to indemnify Morgan Stanley and its affiliates,
their respective directors, officers, agents and employees and each person, if
any, controlling Morgan Stanley or any of its affiliates against certain
liabilities and expenses, including certain liabilities under federal
securities laws, related to or arising out of Morgan Stanley's engagement and
any related transactions.

<PAGE>

completion of the merger, AOL Time Warner will indemnify and hold harmless, and
provide advancement of expenses to, all past and present directors, officers
and employees of America Online and its subsidiaries, in all of their
capacities:
 
  .  to the same extent they were indemnified or had the right to advancement
     of expenses as of January 10, 2000, which is the date of the merger
     agreement, pursuant to America Online's restated certificate of
     incorporation, restated by-laws and indemnification agreements with any

insured, with respect to claims arising from facts or events that occurred on
or before the completion of the merger, although AOL Time Warner will not be
required to expend in any one year an amount in excess of 200% of the annual
premiums currently paid by America Online for directors' and officers'
liability insurance and fiduciary liability insurance.
 
Interests of Certain Time Warner Directors and Executive Officers in the Merger
 
   In considering the recommendation of the board of directors of Time Warner
to vote for the proposal to adopt the merger agreement, stockholders of Time
Warner should be aware that members of the Time Warner board of directors and
members of Time Warner's management team have agreements or arrangements that
provide them with interests in the merger that differ from those of Time Warner
stockholders. The Time Warner board of directors was aware of these agreements
and arrangements during its deliberations of the merits of the merger and in
determining to recommend to the stockholders of Time Warner that they vote for
the proposal to adopt the merger agreement.
 
   Governance Structure and Management Positions. Pursuant to the terms of the
merger agreement, upon completion of the merger:
 
  .  the board of directors of AOL Time Warner will be comprised of sixteen
     individuals, eight of whom will be designated by America Online and
     eight of whom will be designated by Time Warner; and
 
  .  each committee of the board of directors of AOL Time Warner will be
     comprised of two directors designated by America Online and two
     directors designated by Time Warner.
 
   Upon completion of the merger:
 
  .  Gerald M. Levin, Chairman and Chief Executive Officer of Time Warner,
     will serve as Chief Executive Officer of AOL Time Warner, and until

     75% vote of the entire AOL Time Warner board of directors;
 
                                       55

<PAGE>
 
  .  R.E. Turner, Vice Chairman of Time Warner, will serve as Vice Chairman
     of AOL Time Warner; and
 
  .  Richard D. Parsons, President of Time Warner, will serve as Co-Chief
     Operating Officer of AOL Time Warner.
 
   Time Warner Employee Stock Options and Restricted Shares. Upon approval by
the board of directors of Time Warner of the merger agreement, on January 9,
2000, all then outstanding Time Warner employee stock options, by their terms,
immediately vested and became exercisable, and all then outstanding restricted
shares of Time Warner common stock, by their terms, immediately vested and
became free of all restrictions.
 
   Pursuant to the terms of the merger agreement, each Time Warner employee
stock option outstanding immediately prior to the completion of the merger will
be converted, upon completion of the merger, into an option to acquire, on the
same terms and conditions, the number of shares of AOL Time Warner common stock
that is equal to the product of the number of shares of Time Warner common
stock that could have been acquired upon exercise of the option immediately
before completion of the merger multiplied by 1.5, rounded to the nearest whole
share. The exercise price of these AOL Time Warner stock options will be the
exercise price for the Time Warner stock option immediately before completion
of the merger divided by 1.5.
 
   Indemnification and Insurance. The merger agreement provides that, upon
completion of the merger, AOL Time Warner will indemnify and hold harmless, and
provide advancement of expenses to, all past and present directors, officers
and employees of Time Warner and its subsidiaries in all of their capacities:
 
  .  to the same extent they were indemnified or had the right to advancement
     of expenses as of January 10, 2000, which is the date of the merger
     agreement, pursuant to Time Warner's restated certificate of
     incorporation, by-laws and indemnification agreements with any
     directors, officers and employees of Time Warner and its subsidiaries;
     and
 
  .  to the fullest extent permitted by law, in each case for acts or
     omissions occurring at or prior to the completion of the merger.
 
   The merger agreement also provides that, upon completion of the merger, AOL
Time Warner will cause to be maintained, for a period of six years after
completion of the merger, the current policies of directors' and officers'
liability insurance and fiduciary liability insurance maintained by Time
Warner, or policies of at least the same coverage and amounts containing terms
and conditions which are, in the aggregate, no less advantageous to the
insured, with respect to claims arising from facts or events that occurred on
or before the completion of the merger, although AOL Time Warner will not be
required to expend in any one year an amount in excess of 200% of the annual
premiums currently paid by Time Warner for directors' and officers' liability
insurance and fiduciary liability insurance.
 
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 America Online and Time Warner. The merger will become
effective upon the filing of certificates of merger with the Secretary of State
of the State of Delaware.
 
   We are working toward completing the merger as quickly as possible. We
expect to complete the merger during the fall of 2000.
 
Structure of the Merger and Conversion of America Online and Time Warner Stock
 
   Structure. To accomplish the combination of their businesses, America Online
and Time Warner jointly formed a new company, AOL Time Warner with two
subsidiaries, America Online Merger Sub and Time Warner Merger Sub. At the time
the merger is completed:
 
  .  America Online Merger Sub will be merged into America Online, and
     America Online will be the surviving corporation; and
 
                                       56

<PAGE>
 
  .  Time Warner Merger Sub will be merged into Time Warner, and Time Warner
     will be the surviving corporation.
 
As a result, America Online and Time Warner will each become a wholly owned
subsidiary of AOL Time Warner.
 
   Conversion of America Online and Time Warner Stock. When the merger is
completed:
 
  .  America Online common stockholders will receive one share of AOL Time
     Warner common stock for each share they own;
 
  .  Time Warner common stockholders will receive 1.5 shares of AOL Time
     Warner common stock for each share they own;
 
  .  Time Warner series LMCN-V common stockholders will receive 1.5 shares of
     substantially identical AOL Time Warner series LMCN-V common stock for
     each share they own; and
 
  .  Time Warner preferred stockholders will receive one share of a
     corresponding series of substantially identical AOL Time Warner
     preferred stock for each share of each series of Time Warner preferred
     stock they own.
 
   The voting rights and conversion ratio of each series of AOL Time Warner
preferred stock will be adjusted as a result of the merger to reflect the 1.5
conversion ratio between shares of Time Warner common stock and shares of AOL
Time Warner common stock. The voting rights and conversion ratio of the AOL
Time Warner series LMCN-V common stock will not be adjusted.
 
   The number of shares of AOL Time Warner stock issuable in the merger will be
proportionately adjusted for any stock split, stock dividend or similar event
with respect to the America Online common stock or Time Warner capital stock
effected between the date of the merger agreement and the date of completion of
the merger.
 
Exchange of Stock Certificates for AOL Time Warner Stock Certificates
 
   When the merger is completed, the exchange agent will mail to you a letter
of transmittal and instructions for use in surrendering your America Online or
Time Warner stock certificates in exchange for AOL Time Warner stock
certificates. When you deliver your stock certificates to the exchange agent
along with a properly executed letter of transmittal and any other required
documents, your stock certificates will be canceled and you will receive AOL
Time Warner stock certificates representing the number of full shares of AOL
Time Warner stock to which you are entitled under the merger agreement. Time
Warner stockholders will receive payment in cash, without interest, in lieu of
any fractional shares of AOL Time Warner common stock or series common stock
which would have been otherwise issuable to them as a result of the merger.
 
You should not submit your America Online or Time Warner stock certificates for
exchange until you receive the transmittal instructions and a form of letter of
transmittal from the exchange agent.
 
   You are not entitled to receive any dividends or other distributions on AOL
Time Warner common stock until the merger is completed and you have surrendered
your America Online or Time Warner stock certificates in exchange for AOL Time
Warner stock certificates.
 
   If there is any dividend or other distribution on AOL Time Warner stock with
a record date after the date on which the merger is completed and a payment
date prior to the date you surrender your America Online or Time Warner stock
certificates in exchange for AOL Time Warner stock certificates, you will
receive the dividend or distribution with respect to the whole shares of AOL
Time Warner stock issued to you promptly after they are issued. If there is any
dividend or other distribution on AOL Time Warner stock with a record date
after the date on which the merger is completed and a payment date after the
date you surrender your
 
                                       57

<PAGE>
 
America Online or Time Warner stock certificates in exchange for AOL Time
Warner stock certificates, you will receive the dividend or distribution with
respect to the whole shares of AOL Time Warner stock issued to you promptly
after the payment date.
 
   AOL Time Warner will only issue an AOL Time Warner stock certificate or a
check in lieu of a fractional share in a name other than the name in which a
surrendered America Online or Time Warner stock certificate is registered 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.
 
Treatment of America Online and Time Warner Stock Options and Other Equity
Based Awards
 
   When the merger is completed, each outstanding America Online employee stock
option will be converted into an option to purchase shares of AOL Time Warner
common stock at an exercise price per share equal to the exercise price per
share of America Online common stock subject to the option before the
conversion. In addition, each outstanding restricted share of America Online
common stock will be converted into one restricted share of AOL Time Warner
common stock. As a result of the completion of the merger, substantially all
America Online employee stock options, and shares of restricted stock
outstanding on January 10, 2000, by their terms, will vest and become
exercisable or free of restrictions, as the case may be, upon the earliest to
occur of (1) their normal vesting date, (2) the first anniversary of the
completion of the merger and (3) the employee's termination without cause or
constructive termination.
 
   Upon completion of the merger, each outstanding Time Warner stock option
will be converted into an option to purchase the number of shares of AOL Time
Warner common stock that is equal to the product of 1.5 multiplied by the
number of shares of Time Warner common stock that would have been obtained
before the merger upon the exercise of the option, rounded to the nearest whole
share. The exercise price per share will be equal to the exercise price per
share of Time Warner common stock subject to the option before the conversion
divided by 1.5. In addition, each outstanding restricted share of Time Warner
common stock will be converted into the number of restricted shares of AOL Time
Warner common stock that is equal to the product of 1.5 multiplied by the
shares of Time Warner common stock subject to the award. Each Time Warner stock
option outstanding on January 9, 2000, by its terms, accelerated and became
fully vested, and each share of restricted Time Warner common stock outstanding
on that date immediately vested, becoming free of restrictions.
 
   The other terms of each America Online and Time Warner option and restricted
shares, referred to above will continue to apply.
 
   AOL Time Warner will file a registration statement covering the issuance of
the shares of AOL Time Warner common stock subject to each America Online and
Time Warner option and restricted shares and will maintain the effectiveness of
that registration statement for as long as any of the options or restricted
shares remain outstanding.
 
Effect of the Merger on Outstanding America Online Convertible Notes
 
   As of December 31, 1999, America Online had outstanding two series of
convertible subordinated notes: (1) $248,971,000 aggregate principal amount of
4% convertible subordinated notes due November 15, 2002, and (2) $2,267,533,000
aggregate principal amount at maturity of zero coupon convertible subordinated
notes due 2019. On December 31, 1999, the underwriters exercised the
overallotment option on the notes due in 2019. As a result, America Online sold
additional notes with an aggregate principal amount at maturity of
approximately $55.6 million.
 
   The convertible notes due in 2002 were issued under an indenture dated as of
November 17, 1997 between America Online and State Street Bank and Trust
Company, as trustee. The indenture provides that after consummation of the
merger, the note holders will be entitled to convert their notes into the
number of shares of AOL Time Warner common stock that they would have received
in the merger if they had converted the
 
                                       58

<PAGE>
 
notes into America Online common stock immediately prior to the merger. If the
notes are outstanding at the time the merger is consummated, America Online and
AOL Time Warner will enter into a supplemental indenture to implement this
modification in the conversion right of the notes. The merger will not
constitute a "change in control" as defined in the indenture, which would give
the note holders the right to require America Online to repurchase the notes.
 
   The convertible notes due in 2019 were issued under an indenture dated as of
December 6, 1999, as supplemented by a supplemental indenture dated the same
date, between America Online and State Street Bank and Trust Company, as
trustee. Upon consummation of the merger, AOL Time Warner will enter into a
supplemental indenture providing that, subject to the terms and conditions of
the indenture, each note will thereafter be convertible into the number of
shares of AOL Time Warner common stock which the note holder would have
received in the merger if the note holder had converted the note immediately
prior to the merger.
 
Material United States Federal Income Tax Consequences of the Merger
 
   The following summary discusses the material U.S. federal income tax
consequences of the merger to U.S. Holders of America Online and Time Warner
stock.
 
   For purposes of this discussion, a U.S. Holder means:
 
  .  a citizen or resident of the United States;
 
  .  a corporation or other entity taxable as a corporation created or
     organized under the laws of the United States or any of its political
     subdivisions;
 
  .  a trust, if a U.S. court is able to exercise primary supervision over
     the administration of the trust and one or more U.S. fiduciaries have
     the authority to control all substantial decisions of the trust; or
 
  .  an estate that is subject to U.S. federal income tax on its income
     regardless of its source.
 
   This discussion is based upon the Internal Revenue Code of 1986, as amended,
Treasury regulations, administrative rulings and judicial decisions currently
in effect, all of which are subject to change, possibly with retroactive
effect. The discussion assumes that America Online stockholders hold their
America Online common stock and will hold their AOL Time Warner common stock,
and that Time Warner stockholders hold their Time Warner capital stock and will
hold their AOL Time Warner capital stock, as a capital asset within the meaning
of Section 1221 of the Internal Revenue Code. Further, the discussion does not
address all aspects of U.S. federal income taxation that may be relevant to a
particular stockholder in light of his, her or its personal investment
circumstances or to stockholders subject to special treatment under the U.S.
federal income tax laws, including:
 
  .  insurance companies;
 
  .  tax-exempt organizations;
 
  .  dealers in securities or foreign currency;
 
  .  banks or trusts;
 
  .  persons that hold their America Online common stock or Time Warner
     capital stock as part of a straddle, a hedge against currency risk or a
     constructive sale or conversion transaction;
 
  .  persons that have a functional currency other than the U.S. dollar;
 
  .  investors in pass-through entities;
 
  .  stockholders who acquired their America Online common stock or Time
     Warner capital stock through the exercise of options or otherwise as
     compensation or through a tax-qualified retirement plan; or
 
                                       59

<PAGE>
 
  .  holders of options granted under any America Online or Time Warner
     benefit plan.
 
   Furthermore, this discussion does not consider the potential effects of any
state, local or foreign tax laws.
 
   None of America Online, Time Warner or AOL Time Warner has requested a
ruling from the United States Internal Revenue Service with respect to any of
the U.S. federal income tax consequences of the merger and, as a result, there
can be no assurance that the Internal Revenue Service will not disagree with or
challenge any of the conclusions described below.
 
   Simpson Thacher & Bartlett, counsel to America Online, has delivered its
opinion to America Online and Cravath, Swaine & Moore, counsel to Time Warner,
has delivered its opinion to Time Warner, each dated as of the Closing Date, to
the effect that, on the basis of the facts, representations and assumptions set
forth in such opinion, the exchange of America Online common stock or Time
Warner capital stock for AOL Time Warner capital stock in the merger will
constitute an exchange to which Section 351 of the Internal Revenue Code
applies or a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code, or both. Any change in currently applicable law, which
may or may not be retroactive, or failure of any factual representations or
assumptions to be true, correct and complete in all material respects, could
affect the continuing validity of the Simpson tax opinion and the Cravath tax
opinion.
 
   Based on such tax opinions, the following tax consequences would arise:
 
  .  no gain or loss will be recognized by AOL Time Warner, America Online,
     Time Warner, America Online Merger Sub or Time Warner Merger Sub in
     connection with the merger;
 
  .  no gain or loss will be recognized by (i) U.S. Holders of America Online
     common stock on the exchange of their America Online common stock for
     AOL Time Warner common stock or (ii) U.S. Holders of Time Warner capital
     stock on the exchange of their Time Warner capital stock for AOL Time
     Warner capital stock (except with respect to cash received by U.S.
     Holders of Time Warner capital stock in lieu of fractional shares of AOL
     Time Warner capital stock);
 
  .  (i) the aggregate adjusted basis of the AOL Time Warner common stock
     received in the merger by a U.S. Holder of America Online common stock
     will be equal to the aggregate adjusted basis of the U.S. Holder's
     America Online common stock exchanged for that AOL Time Warner common
     stock and (ii) the aggregate adjusted basis of the AOL Time Warner
     capital stock received in the merger by a U.S. Holder of Time Warner
     capital stock will be equal to the aggregate adjusted basis of the U.S.
     Holder's Time Warner capital stock exchanged for that AOL Time Warner
     capital stock (reduced by any amount allocable to the fractional share
     interests in AOL Time Warner capital stock for which cash is received);
     and
 
  .  (i) the holding period of the AOL Time Warner common stock received in
     the merger by a U.S. Holder of America Online common stock will include
     the holding period of the U.S. Holder's America Online common stock
     exchanged for that AOL Time Warner common stock and (ii) the holding
     period of the AOL Time Warner capital stock received in the merger by a
     U.S. Holder of Time Warner capital stock will include the holding period
     of the U.S. Holder's Time Warner capital stock exchanged for that AOL
     Time Warner capital stock.
 
   Cash Instead of Fractional Shares. The receipt of cash instead of a
fractional share of AOL Time Warner capital stock by a U.S. Holder of Time
Warner capital stock will result in taxable gain or loss to such U.S. Holder
for U.S. federal income tax purposes based upon the difference between the
amount of cash received by such U.S. Holder and the U.S. Holder's adjusted tax
basis in the fractional share as set forth above. The gain or loss will
constitute capital gain or loss and will constitute long-term capital gain or
loss if the U.S. Holder's holding period is greater than 12 months as of the
date of the merger. For non-corporate U.S. Holders, this long-term capital gain
generally will be taxed at a maximum U.S. federal income tax rate of 20%. The
deductibility of capital losses is subject to limitations.
 
                                       60

<PAGE>
 
   Appraisal Rights.  A Time Warner stockholder who exercises appraisal rights
generally will recognize taxable capital gain or loss based upon the difference
between the amount of cash received by such U.S. Holder and the U.S. Holder's
tax basis in the shares of Time Warner capital stock exchanged.
 
   Backup Withholding.  Certain non-corporate Time Warner stockholders may be
subject to backup withholding at a 31% rate on cash payments received instead
of fractional shares of AOL Time Warner capital stock. Backup withholding will
not apply, however, to a Time Warner 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 Time Warner 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.
 
   Reporting Requirements.  A U.S. Holder of America Online common stock or
Time Warner capital stock receiving AOL Time Warner capital stock as a result
of the merger may be required to retain records related to such U.S. Holder's
America Online common stock and Time Warner capital stock, as the case may be,
and file with its federal income tax return, a statement setting forth facts
relating to the merger.
 
   The summary of material U.S. federal income tax consequences is intended to
provide only a general summary and is not intended to be a complete analysis or
description of all potential federal income tax consequences of the merger. In
addition, the summary does not address tax consequences that may vary with, or
are contingent on, individual circumstances. Moreover, the summary does not
address any non-income tax or any foreign, state or local tax consequences of
the merger. The summary does not address the tax consequences of any
transaction other than the merger. Accordingly, each America Online and Time
Warner stockholder is strongly urged to consult with a tax advisor to determine
the particular federal, state, local or foreign income or other tax
consequences of the merger to the holder.

   We have summarized below the material regulatory requirements affecting the
merger. Although we have not yet received the required approvals we discuss, we
anticipate that we will receive regulatory approvals sufficient to complete the
merger by the fall of 2000.
 
   Antitrust Considerations. The merger is subject to the requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, 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 specified waiting periods are terminated or
expire. We have filed the required information and materials with the
Department of Justice and the Federal Trade Commission.
 
   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
 
                                       61

<PAGE>
 
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.
 
   Under Regulation (EEC) No. [4064/89] of the Council of the European Union,
the merger may not be completed until the European Commission has granted its
approval. America Online and Time Warner anticipate that the requisite
notification will be filed with respect to the merger with the European
Commission. In addition, America Online and Time Warner are required to make
filings with or obtain approvals from other international regulatory
authorities in connection with the merger including regulatory authorities in
Brazil, Canada and South Africa.
 
   America Online and Time Warner are not aware of any other foreign
governmental approvals or actions that are required to complete the merger.
America Online and Time Warner conduct operations in a number of foreign
countries, some of which have voluntary and/or post-merger notification
systems. Should any other approval or action be required, America Online and
Time Warner currently plan to seek the approval or take the action. Failure to
obtain the approval or take the action is not anticipated to have a material
effect on the merger or on AOL Time Warner.
 
   Federal Communications Commission. Pursuant to the Communications Act of
1934, the transfer of control of licenses issued by the Federal Communications
Commission typically requires prior Federal Communications Commission approval.
America Online and Time Warner each directly or indirectly hold Federal
Communications Commission licenses and intend to obtain any necessary approvals
from the Federal Communications Commission in connection with the mergers. On
or about [    ], 2000, America Online and Time Warner filed appropriate
applications with the Federal Communications Commission seeking approval for
the transfer of control to AOL Time Warner of the applicable Federal
Communications Commission licenses and authorizations.
 
   State and Local Governmental Authorities. Affiliates of Time Warner hold
cable television franchises around the country for its cable television
operations. A substantial number of these cable franchise agreements may
require local governmental approval in connection with the merger, and a few
states may impose similar requirements. Similarly, a few state and local
approvals may be required in connection with the transfer of control of
authorizations for telephone or telecommunications services provided by
affiliates of Time Warner. Time Warner and AOL Time Warner submitted
applications to appropriate state and local authorities where consents may be
required. Other state and local authorities have been provided notification of
the merger.
 
Restrictions on Sales of Shares by Affiliates of America Online and Time Warner
 
   The shares of AOL Time Warner common stock to be issued in connection with
the merger or upon conversion of shares of AOL Time Warner series common stock
or AOL Time Warner preferred stock issued in connection with the merger will be
registered under the Securities Act of 1933 and will be freely transferable
under the Securities Act, except for shares of AOL Time Warner common stock
issued to any person who is deemed to be an "affiliate" of either America
Online or Time Warner at the time of the special meetings. 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 America Online or Time
Warner and may include our executive officers and directors, as well as our
significant stockholders. Affiliates may not sell their shares of AOL Time
Warner 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.
 
                                       62

<PAGE>
 
   AOL Time Warner's registration statement on Form S-4, of which this joint
proxy statement-prospectus forms a part, does not cover the resale of shares of
AOL Time Warner common stock to be received by our affiliates in the merger.
 
New York Stock Exchange Listing of AOL Time Warner Common Stock to be Issued in
the Merger
 
   AOL Time Warner will use reasonable best efforts to cause the shares of AOL
Time Warner 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.
 
Appraisal Rights
 
   The following summary of the provisions of Section 262 of the Delaware
General Corporation Law is not intended to be a complete statement of the
provisions and is qualified in its entirety by reference to the full text of
Section 262 of the Delaware General Corporation Law, a copy of which is
attached to this joint proxy statement-prospectus as annex I and is
incorporated into this summary by reference.
 
   Under Delaware law, America Online stockholders and Time Warner common
stockholders are not entitled to appraisal rights in connection with the
merger. However, holders of Time Warner series common stock and preferred stock
are entitled to appraisal rights under Delaware law.
 
   If the merger is approved by the required vote of Time Warner's
stockholders, each holder of Time Warner series common stock and preferred
stock who (1) files written notice with Time Warner of an intention to exercise
rights to appraisal of his, her or its shares prior to the Time Warner special
meeting, (2) in the case of a preferred stockholder, does not vote in favor of
the merger and (3) follows the procedures set forth in Section 262, will be
entitled to be paid for his or her Time Warner series common stock or preferred
stock by the surviving corporation the fair value in cash of the shares of Time
Warner series common stock or preferred stock, as the case may be. The fair
market value of shares of Time Warner series common stock and preferred stock
will be determined by the Delaware Court of Chancery, exclusive of any element
of value arising from the merger. The shares of Time Warner series common stock
and preferred stock with respect to which holders have perfected their
appraisal rights in accordance with Section 262 and have not effectively
withdrawn or lost their appraisal rights are referred to in this joint proxy
statement-prospectus as the "dissenting shares."
 
   Within ten days after the effective date of the merger, Time Warner, as the
surviving corporation in the merger, must mail a notice to all stockholders who
have complied with (1) and (2) above notifying such stockholders of the
effective date of the merger. Within 120 days after the effective date, holders
of Time Warner series common stock and preferred stock may file a petition in
the Delaware Court of Chancery for the appraisal of their shares, although they
may, within 60 days of the effective date, withdraw their demand for appraisal.
Notwithstanding the foregoing, within 120 days of the effective date, the
holders of dissenting shares may also, upon written request, receive from AOL
Time Warner a statement setting forth the aggregate number of shares with
respect to which demands for appraisals have been received.
 
   Appraisal rights are available only to the record holder of shares. If you
wish to exercise appraisal rights but have a beneficial interest in shares
which are held of record by or in the name of another person, such as a broker
or nominee, you should act promptly to cause the record holder to follow the
procedures set forth in Section 262 to perfect your appraisal rights.
 
   A demand for appraisal should be signed by or on behalf of the stockholder
exactly as the stockholder's name appears on the stockholder's stock
certificates. If the shares are owned of record in a fiduciary capacity, such
as by a trustee, guardian or custodian, the demand should be executed in that
capacity, and if the shares are owned of record by more than one person, as in
a joint tenancy or tenancy in common, the demand should be executed by or on
behalf of all joint owners. An authorized agent, including one or more joint
owners, may execute a demand for appraisal on behalf of a record holder;
however, in the demand the agent must identify
 
                                       63

<PAGE>
 
the record owner or owners and expressly disclose that the agent is executing
the demand as an agent for the record owner or owners. A record holder such as
a broker who holds shares as nominee for several beneficial owners may exercise
appraisal rights for the shares held for one or more beneficial owners and not
exercise rights for the shares held for other beneficial owners. In this case,
the written demand should state the number of shares for which appraisal rights
are being demanded. When no number of shares is stated, the demand will be
presumed to cover all shares held of record by the broker or nominee.
 
   If any holder of Time Warner series common stock or preferred stock who
demands the appraisal and purchase of his or her shares under Section 262 fails
to perfect, or effectively withdraws or loses the right to the purchase, his or
her shares will be converted into a right to receive a number of shares of AOL
Time Warner series common stock or preferred stock, as the case may be, in
accordance with the terms of the merger agreement. Dissenting shares lose their
status as dissenting shares if:
 
  .  the merger is abandoned;
 
  .  the dissenting stockholder fails to make a timely written demand for
     appraisal;
 
  .  the dissenting shares are voted in favor of the merger;
 
  .  neither Time Warner nor the stockholder files a complaint or intervenes
     in a pending action within 120 days after mailing of the approval
     notice; or
 
  .  the stockholder delivers to AOL Time Warner, as the surviving
     corporation, a written withdrawal of the stockholder's demand for
     appraisal of the dissenting shares.
 
Failure to follow the steps required by Section 262 of the Delaware General
Corporation Law for perfecting appraisal rights may result in the loss of
appraisal rights, in which event a Time Warner stockholder will be entitled to
receive the consideration with respect to the holder's dissenting shares in
accordance with the merger agreement. In view of the complexity of the
provisions of Section 262 of the Delaware General Corporation Law, Time Warner
stockholders who are considering objecting to the merger should consult their
own legal advisors.
 
Delisting and Deregistration of America Online and Time Warner Common Stock
after the Merger
 
   When the merger is completed, America Online common stock and Time Warner
common stock will each be delisted from the New York Stock Exchange and will be
deregistered under the Securities Exchange Act of 1934.
 
Stockholder Lawsuits Challenging the Merger
 
   Several complaints have been filed in the Delaware Court of Chancery or
Supreme Court of New York naming as defendants one or more of (a) America
Online, (b) the directors of America Online, (c) Time Warner and (d) the
directors of Time Warner. The complaints purport to be filed on behalf of
holders of America Online stock or Time Warner stock, as applicable, and allege
breaches of fiduciary duty by the applicable company and its directors or
aiding and abetting breaches of fiduciary duty by the other company and its
directors in connection with the proposed merger of America Online and Time
Warner. The plaintiffs in each case seek to enjoin completion of the merger
and/or damages. Each of America Online and Time Warner intends to defend
against these lawsuits vigorously.

by reference to the complete text of the merger agreement, which is

     filings with, or notices to, any state or local cable franchising
     authorities or any state public service commissions necessary for
     completion of the merger, the failure of which to obtain, individually
     or in the aggregate, would not reasonably be expected to have a Material
     Adverse Effect, as described below, on AOL Time Warner after the merger;
 
  .  the approval for listing, by the New York Stock Exchange, of the shares
     of AOL Time Warner common stock to be issued, or to be reserved for

   However, there will be no Material Adverse Effect to the extent that any
event, change, circumstance or effect relates:
 
  .  to the economy or financial markets in general; or
 
  .  generally to the industries in which the entity operates.

       date; and
 
 
                                       65

<PAGE>
 
    .  any failure of such representations and warranties to be true and
       correct that would not, individually or in the aggregate, reasonably
       be expected to have a Material Adverse Effect on Time Warner;
 
  .  Time Warner must have:
 
    .  performed or complied with all agreements and covenants required to
       be performed by it under the merger agreement that are qualified as
       to materiality or Material Adverse Effect; and

     368(a) of the Internal Revenue Code, or both; and
 
  .  conditions for the benefit of Time Warner must have been satisfied or
     waived by Time Warner.
 
   Time Warner's obligations to complete the merger relating to Time Warner are
subject to the satisfaction or waiver of the following additional conditions
before completion of the merger:
 
  .  America Online's representations and warranties, disregarding all
     qualifications and exceptions contained in the merger agreement relating

     the Internal Revenue Code, or both; and
 
  .  conditions for the benefit of America Online must have been satisfied or
     waived by America Online.
 
   No Other Transactions Involving America Online or Time Warner.  The merger
agreement contains detailed provisions prohibiting America Online and Time
Warner from seeking an alternative transaction. Under these "no solicitation"
provisions, each of America Online and Time Warner has agreed that neither it
nor any of its subsidiaries, officers and directors, will, and that it will use
reasonable best efforts to ensure that its and its subsidiaries' employees,
agents and representatives, do not, directly or indirectly:
 
  .  initiate, solicit, encourage or knowingly facilitate any inquires or the
     making of an Acquisition Proposal, as described below;
 
  .  have any discussion with, or provide any confidential information or
     data to, any person relating to an Acquisition Proposal, or engage in
     any negotiations concerning an Acquisition Proposal, or knowingly
     facilitate any effort or attempt to make or implement an Acquisition
     Proposal;
 
                                       66

<PAGE>
 
  .  approve or recommend, or propose publicly to approve or recommend, any
     Acquisition Proposal; or
 
  .  approve or recommend, or propose to approve or recommend, or execute or
     enter into, any letter of intent, agreement in principle, merger
     agreement, acquisition agreement, option agreement or other similar
     agreement or propose publicly or agree to do any of the foregoing
     related to any Acquisition Proposal.
 
   "Acquisition Proposal" means, with respect to any entity, any proposal or
offer with respect to, or a transaction to effect:
 
  .  a merger, reorganization, share exchange, consolidation, business
     combination, recapitalization, liquidation, dissolution or similar
     transaction involving that entity or any of its significant
     subsidiaries;
 
  .  any purchase or sale of 20% or more of the consolidated assets of the
     entity, including stock of its subsidiaries, taken as a whole; or
 
  .  any purchase or sale of, or tender or exchange offer for, the equity
     securities of that entity that, if completed, would result in any person
     beneficially owning securities representing 20% or more of the total
     voting power of that entity, or of the surviving parent entity in the
     transaction, or any of its significant subsidiaries.
 
   However, the merger agreement does not prevent each of America Online and
Time Warner, or its board of directors from:
 
  .  engaging in any discussions or negotiations with, or providing any
     information to, any person in response to an unsolicited bona fide
     written Acquisition Proposal by that person, if and only to the extent
     that its board of directors concludes in good faith that there is a
     reasonable likelihood that the Acquisition Proposal could constitute a
     Superior Proposal; or
 
  .  effecting a Change in Board Recommendation, as defined below, if and
     only to the extent that it has received an unsolicited bona fide written
     Acquisition Proposal from a third party and its board of directors
     concludes in good faith that the Acquisition Proposal constitutes a
     Superior Proposal, as described below.
 
   However, America Online or Time Warner may only take such action if and only
to the extent that:
 
  .  the special meeting of its stockholders to vote on the adoption of the
     merger agreement has not occurred;
 
  .  its board of directors, after consultation with outside counsel,
     determines in good faith that the failure to effect a Change in Board
     Recommendation or to engage in discussions or negotiations with, or
     provide information to, the person, as the case may be, would be
     inconsistent with its fiduciary duties under applicable law;
 
  .  before providing any information or data to any person in connection
     with an Acquisition Proposal by that person, its board of directors
     receives from that person an executed confidentiality agreement with
     customary provisions; except that if the confidentiality agreement
     contains provisions that are less restrictive than the comparable
     provision, or omits restrictive provisions, contained in the
     confidentiality agreement between America Online and Time Warner, then
     the confidentiality agreement between America Online and Time Warner
     will be automatically amended to contain the less restrictive provisions
     or to omit the restrictive provisions, as the case may be; and
 
  .  before providing any information or data to any person or entering into
     discussions or negotiations with any person, it promptly notifies the
     other party of:
 
    .  inquiries, proposals or offers received by, any information
       requested from, or any discussions or negotiations sought to be
       initiated or continued with, any of its representatives; and
 
                                       67

<PAGE>
 
    .  the name of the person and the material terms and conditions of any
       inquiries, proposals or offers.
 
   In addition, the merger agreement does not prevent America Online or Time
Warner from complying with Rule 14d-9 and Rule 14e-2 promulgated under the
Securities Exchange Act of 1934 with regard to an Acquisition Proposal.
 
   "Change in Board Recommendation" means, with respect to any party to the
merger agreement:
 
  .  withdrawing, modifying or qualifying, or proposing to withdraw, modify
     or qualify, in any manner adverse to the other party to the merger
     agreement, the recommendation of that party's board of directors that
     its stockholders vote in favor of the adoption of the merger agreement;
     or
 
  .  taking any action or making any statement in connection with the special
     meeting of the stockholders of that party that is inconsistent with the
     recommendation of that party's board of directors.
 
  However, an action or statement will not be a Change in Board
     Recommendation so long as:
 
    .  the action or statement is taken or made pursuant to advice, in the
       case of America Online, from Simpson Thacher & Bartlett, and, in the
       case of Time Warner, from Cravath, Swaine & Moore, to the effect
       that the action or statement is required by applicable law;
 
    .  if a Public Proposal, as described below, has been made and not
       rescinded, the action or statement does not relate to the Public
       Proposal other than any factual statement required by any regulatory
       authority, and the action or statement includes a rejection of the
       Public Proposal; and
 
    .  the action or statement also includes a reaffirmation of the
       approval of the merger by that party's board of directors and the
       recommendation to that party's stockholders to adopt the merger
       agreement.
 
   "Public Proposal" means, with respect to America Online or Time Warner, an
Acquisition Proposal that has been publicly announced or otherwise communicated
to the senior management, board of directors or stockholders of America Online
or Time Warner, as the case may be, at any time after January 10, 2000, the
date of the merger agreement.
 
   The board of directors of America Online or Time Warner may only change
their respective recommendations of the merger as provided in the "no
solicitation" provision of the merger agreement.
 
   "Superior Proposal" means a bona fide written proposal made to America
Online or Time Warner, as the case may be, which is for a merger,
reorganization, consolidation, share exchange, business combination,
recapitalization or similar transaction involving America Online or Time
Warner; and
 
  .  as a result of which the person making the proposal or its stockholders
     will own 40% or more of the combined voting power of the entity
     surviving or resulting from the transaction, or its ultimate parent
     entity; and
 
  .  is on terms which the board of directors of America Online or Time
     Warner, as the case may be, in good faith concludes, following receipt
     of the advice of its financial advisors and outside counsel, taking into
     account, among other things, all legal, financial, regulatory and other
     aspects of the proposal and the person making the proposal:
 
    .  would, if completed, result in a transaction that is more favorable
       to the stockholders of America Online or Time Warner, as the case
       may be, from a financial point of view, than the merger; and
 
    .  is reasonably capable of being completed.
 
   Each of America Online and Time Warner has agreed under the provisions of
the merger agreement that:
 
  .  it will promptly keep the other party informed of the status and terms
     of any proposals, offers, discussions or negotiations covered by the "no
     solicitation" provisions of the merger agreement;
 
                                       68

<PAGE>
 
  .  it will, and its officers, directors and representatives will,
     immediately cease and terminate any activities, discussions or
     negotiations existing as of January 10, 2000, the date of the merger
     agreement, with any parties conducted before that date with respect to
     any Acquisition Proposal;
 
  .  it will use reasonable best efforts to promptly inform its directors,
     officers, key employees, agents and representatives of the obligations
     of the "no solicitation" provisions of the merger agreement; and
 
  .  it will not submit to the vote of its stockholders any Acquisition
     Proposal other than the merger between America Online and Time Warner.
 
   Nothing contained in the "no solicitation" provisions of the merger
agreement will:
 
  .  permit America Online or Time Warner to terminate the merger agreement,
     except as specifically provided in the merger agreement; or
 
  .  affect any other obligation of America Online or Time Warner under the
     merger agreement.
 
   Termination. The merger agreement may be terminated at any time prior to the
completion of the merger, whether before or after the stockholder approvals
have been obtained:
 
  .  by mutual written consent of America Online and Time Warner;
 
  .  by either America Online or Time Warner if the merger is not completed
     on or before May 31, 2001, except that this right to terminate the
     merger agreement will not be available to any party whose failure to
     fulfill any obligation under the merger agreement has been the cause of,
     or has resulted in, the failure of the merger to be completed by May 31,
     2001;
 
  .  by either America Online or Time Warner if any governmental entity:
 
    .  issues an order, decree or ruling or takes any other action
       permanently restraining, enjoining or otherwise prohibiting the
       merger, and the order, decree, ruling or other action becomes final
       and nonappealable; or
 
    .  fails to issue an order, decree or ruling or to take any other
       action, and the denial of a request to issue an order, decree,
       ruling or take any other action becomes final and nonappealable,
 
   in each case which is necessary to fulfill the conditions to the completion
of the merger relating to:
 
      .  the expiration or termination of the applicable waiting periods
         under the Hart-Scott-Rodino Antitrust Improvements Act of 1976;
 
      .  the approval of the merger by the European Commission and
         Canadian governmental entities;
 
      .  the final approval of the Federal Communications Commission;
 
      .  the receipt of all approvals and consents of, and the completion
         of filings with, or notices to, any state cable franchising
         authorities or any state public service commissions necessary for
         completion of the merger, the failure of which to obtain,
         individually or in the aggregate, would not reasonably be
         expected to have a Material Adverse Effect on AOL Time Warner
         after the merger;
 
  except that this right to terminate the merger agreement will not be
  available to any party whose failure to comply with the provisions of the
  merger agreement relating to the use of reasonable best efforts to do all
  things necessary, proper or advisable under the merger agreement and
  applicable laws and regulations to complete the merger is the cause of the
  action or inaction;
 
  .  by either America Online or Time Warner if the approval of either
     party's stockholders is not obtained because of the failure to obtain
     the required vote to adopt the merger agreement at a duly held meeting
     of America Online's or Time Warner's stockholders;
 
 
                                       69

  .  by either America Online or Time Warner if:
 
    .  the board of directors of the other party fails to recommend that
       the stockholders of that party vote in favor of the adoption of the
       merger agreement or effects a Change of Recommendation, whether or
       not permitted by the terms of the merger agreement; or
 
    .  the other party materially breaches its obligations under the merger
       agreement because of a failure to call a special meeting of its
       stockholders to vote on the adoption of the merger agreement or a
       failure to mail this joint proxy statement-prospectus to its
       stockholders; or
 
  .  by either America Online or Time Warner if the other party breaches or
     fails to perform any of its representations, warranties, covenants or
     other agreements contained in the merger agreement in such a way as to
     render the conditions to the completion of the merger relating to the
     accuracy of representations and warranties and the performance of or
     compliance with agreements and covenants contained in the merger
     agreement incapable of being satisfied on or before May 31, 2001.
 
   Effect of Termination. As set forth in more detail below, the merger
agreement requires America Online and Time Warner to pay a termination fee to
one another in specified circumstances in amounts, depending on the
circumstances surrounding the termination, equal either to 2.75% or 1% of its
fully diluted number of shares multiplied by the closing price of America
Online's common stock on January 7, 2000, further multiplied, in the case of
Time Warner, by 1.5.
 
   Time Warner Termination Fee. If either party terminates the merger agreement
because:
 
    .  the approval of the stockholders of Time Warner is not obtained; or
 
    .  the merger is not completed on or before May 31, 2001 and the
       special meeting of Time Warner's stockholders to vote on the
       adoption of the merger agreement has not occurred; and
 
  .  an Acquisition Proposal with respect to Time Warner has been publicly
     announced or otherwise communicated to the senior management, board of
     directors or stockholders of Time Warner at any time after January 10,
     2000, the date of the merger agreement, and before the date of
     termination of the merger agreement; and
 
  .  within 12 months of the termination of the merger agreement, Time Warner
     or any of its subsidiaries enters into any definitive agreement with
     respect to, or consummates, an Acquisition Proposal involving 40% or
     more of the consolidated assets of Time Warner and its subsidiaries,
     taken as a whole, or 40% or more of the total voting power of Time
     Warner, or of the surviving parent entity in the transaction, or any of
     its significant subsidiaries; or
 
   if America Online terminates the merger agreement because:
 
    .  the board of directors of Time Warner fails to recommend that the
       stockholders of Time Warner vote in favor of the adoption of the
       merger agreement or effects a Change of Recommendation; or
 
    .  Time Warner materially breaches its obligations under the merger
       agreement because of its failure to call a special meeting of its
       stockholders to vote on the adoption of the merger agreement or its
       failure to mail this joint proxy statement-prospectus to its
       stockholders;
 
  then Time Warner must pay America Online an amount equal to 2.75% of the
  Time Warner Termination Amount, as described below, less any amounts
  previously paid or payable by Time Warner in connection with the
  termination of the merger agreement, as described in the next sentence. In

  has otherwise been paid in connection with the termination of the merger
  agreement as described in the previous sentence.

"Time Warner Termination Amount" means an amount equal to the product of:
 
     (x) the number of shares of common stock of Time Warner outstanding as

  America Online, and the conversion into Time Warner common stock of all

merger agreement because:
 
    .  the approval of the stockholders of America Online is not obtained;
       or
 
    .  the merger is not completed on or before May 31, 2001 and the
       special meeting of America Online's stockholders to vote on the
       adoption of the merger agreement has not occurred; and
 
  .  an Acquisition Proposal with respect to America Online has been publicly
     announced or communicated to the senior management, board of directors

     subsidiaries, taken as a whole, or 40% or more of the total voting power
     of America Online, or of the surviving parent entity in the transaction,
     or any of its significant subsidiaries; or
 
   if Time Warner terminates the merger agreement because:
 
    .  the board of directors of America Online fails to recommend that the
       stockholders of America Online vote in favor of the adoption of the
       merger agreement or effects a Change of Recommendation; or
 
    .  America Online materially breaches its obligations under the merger
       agreement because of its failure to call a special meeting of its
       stockholders to vote on the adoption of the merger agreement or its
       failure to mail this joint proxy statement-prospectus to its
       stockholders;
 
then America Online must pay Time Warner an amount equal to 2.75% of the
America Online Termination Amount, as described below, less any amounts
previously paid or payable by America Online in connection with the
termination of the merger agreement, as described in the next sentence. In
addition, America Online must pay Time Warner an amount equal to 1% of the
America Online Termination Amount if either party terminates the merger
agreement because the approval of the stockholders of America Online is not
obtained; except that this amount need not be paid if the termination fee has
otherwise been paid in connection with the termination of the merger
agreement, as described in the previous sentence.

America Online and Time Warner has agreed that, during the period before
completion of the merger, except as expressly contemplated or permitted by the

in the same manner as previously conducted, and will use its reasonable best
efforts to preserve intact its present line of business and its relationships
with third parties. Each of America Online and Time Warner has also agreed that
it will not, and it will not permit any of its subsidiaries to, enter into any
new material line of business or incur or commit any capital expenditures or

  .  compensation of directors, executive officers and key employees;
 
  .  accounting policies and procedures;

       interactive services, programming or functionality on the cable
       systems owned by Time Warner or its subsidiaries or affiliates;
 
    .  agreements that limit or restrict, or after completion of the
       merger, could limit or restrict America Online, Time Warner or any
       of their subsidiaries or affiliates, including AOL Time Warner, from
       engaging or competing in any line of business or in any geographic
       area, which limitation would, individually or in the aggregate,
       reasonably be expected to have a Material Adverse Effect on AOL Time
       Warner and its subsidiaries, taken together, after the merger; and
 
  .  actions that would result, or would reasonably be expected to result, in
     any of the conditions to the merger not being satisfied, or a material

   Additional Agreements. Each of America Online and Time Warner has agreed to
cooperate with each other and to use its reasonable best efforts to take all
actions and do all things necessary, proper and advisable

under the merger agreement and applicable laws to complete the merger as soon
as practicable after January 10, 2000, which is the date of the merger
agreement. Accordingly, each has agreed to use its reasonable best efforts to:
 
  .  as promptly as practicable, prepare and file all applications, notices,
     petitions, filings, tax ruling requests and other documents, and to
     obtain all consents, waivers, licenses, orders registrations, approvals,
     permits, rulings, authorizations and clearances from any third party or

actions challenging the merger as illegal and laws or orders making the merger
illegal or prohibiting or materially impairing or delaying the merger. Neither
America Online nor Time Warner will be required to divest or hold separate any
business or assets or take any other action if doing so would, individually or
in the aggregate, reasonably be expected to have a Material Adverse Effect on
AOL Time Warner or if the action is not conditional on the completion of the
merger.

statement-prospectus and additional agreements between them relating to, among

of the New York Stock Exchange requires further approval by the stockholders of
America Online or Time Warner, as the case may be, without the further
approval. All amendments to the merger agreement must be in writing signed by
each party.
 
   At any time before the completion of the merger, the parties may, by action
taken or authorized by their respective boards of directors, to the extent
legally allowed:
 
  .  extend the time for the performance of any of the obligations or other
     acts of the other parties;

  .  the Time Warner stock option agreement, under which Time Warner granted
     to America Online an irrevocable option to purchase, in whole or in
     part, an aggregate of up to 233,263,204 shares of Time Warner common
     stock at a price of $110.63 per share; and

     part, an aggregate of up to 452,535,148 shares of America Online common
     stock at a price of $73.75 per share.
 
   Exercise of the Options. The option granted by Time Warner to America Online
pursuant to the Time Warner stock option agreement may be exercised, in whole
or in part, at any time, after the date on which America Online becomes

termination fees pursuant to the merger agreement. Similarly, the option
granted by America Online to Time Warner pursuant to the America Online stock
option agreement may be exercised, in whole or in part, at any time, after the
date on which Time Warner becomes unconditionally entitled to receive the
larger of the two America Online termination fees pursuant to the merger
agreement.
 
   The right to purchase shares of common stock under each of the Time Warner
stock option agreement and the America Online stock option agreement will
expire on the first to occur of:
 
  .  the completion of the merger;
 
  .  written notice of termination of the Time Warner stock option agreement
     by America Online or written notice of termination of the America Online
     stock option agreement by Time Warner, as the case may be;
 
  .  in the case of the Time Warner stock option agreement, 12 months after
     the date on which America Online becomes unconditionally entitled to
     receive the larger of the two Time Warner termination fees and, in the
     case of the America Online stock option agreement, 12 months after the
     date on which Time Warner becomes unconditionally entitled to receive
     the larger of the two America Online termination fees; or
 
  .  the date of termination of the merger agreement, unless:
 
    .  in the case of the Time Warner stock option agreement, America
       Online has the right to receive the larger Time Warner termination
       fee either upon or following the termination of the merger agreement
       upon the occurrence of certain events, in which case the right to
       purchase shares of common stock under the Time Warner stock option
       agreement will not terminate until the later of:
 
      .  15 business days after the option becomes exercisable; and
 
      .  the expiration of the period in which America Online has the
         right to receive the larger Time Warner termination fee; and
 
  .  in the case of the America Online stock option agreement, Time Warner
     has the right to receive the larger America Online termination fee
     either upon or following the termination of the merger agreement upon
     the occurrence of certain events, in which case the right to right to
     purchase shares of common stock under the America Online stock option
     agreement will not terminate until the later of:
 
    .  15 business days after the option becomes exercisable; and
 
    .  the expiration of the period in which Time Warner has the right to
       receive the larger America Online termination fee.
 
   Any purchase of shares of Time Warner common stock by America Online under
the Time Warner stock option agreement and any purchase of shares of America
Online common stock by Time Warner under the America Online stock option
agreement will occur only if:
 
  .  the purchase would not otherwise violate any applicable material law,
     statute, ordinance, rule or regulation, including the Hart-Scott-Rodino
     Antitrust Improvements Act and the Communications Act of 1934; and
 
                                       75

<PAGE>
 
  .  no material judgment, order, writ, injunction, ruling or decree of any
     governmental entity is promulgated, enacted, entered into or enforced by
     any governmental entity which prohibits the delivery of the shares of
     common stock subject to the applicable stock option agreement.
 
   Each of America Online and Time Warner has agreed, in each stock option
agreement, to use their reasonable best efforts to:
 
  .  Promptly make and process all necessary filings and applications, obtain
     all consents, and approvals, and comply with all applicable laws; and
 
  .  have any judgment, order, writ, injunction, ruling or decree of any
     governmental entity vacated or reversed.
 
   Adjustments Upon Changes in Capitalization and Substitute Option. The number
and kind of securities subject to each stock option agreement and the exercise
price will be adjusted for any change in the number of issued and outstanding
shares of common stock of the issuer of the option in the event of any change
in the corporate or capital structure of the issuer which would have the effect
of diluting or otherwise diminishing the optionholder's rights under the stock
option agreement. Accordingly, the optionholder will receive, upon exercise of
the option, the number and kind of shares or other securities or property that
the optionholder would have received if the option had been exercised
immediately before the event or record date for the event, as applicable. In
addition, if additional shares of common stock of the issuer of each option
become outstanding after January 10, 2000, the date of each option agreement,
the total number of shares of that issuer's common stock subject to the option
shall be increased to 19.9% of all the issued and outstanding shares of that
issuer's common stock.
 
   In the event that the issuer of either option enters into any agreement:
 
  .  to consolidate with or merge into any person other than the optionholder
     or any of its subsidiaries, and the issuer of the option will not be the
     continuing or surviving corporation in the consolidation or merger;
 
  .  to permit any person, other than the optionholder or any of its
     subsidiaries, to merge into the issuer of the option and the issuer of
     the option will be the continuing or surviving or acquiring corporation
     but, in connection with the merger,
 
  .  the then outstanding shares of common stock of the issuer of the option
     will be changed into or exchanged for stock or other securities of any
     other person or cash or any other property; or
 
  .  the outstanding shares of common stock of the issuer of the option will,
     after the merger, represent less than 50% of the outstanding voting
     securities of the merged or acquiring company;
 
  .  to sell or otherwise transfer all or substantially all of its assets to
     any person, other than the optionholder and its subsidiaries,
 
then, in each case, the agreement governing the transaction must contain a
provision that, unless exercised earlier by the optionholder, the option
granted under the stock option agreement will, upon completion of the
transaction and upon specified terms and conditions, be converted into, or
exchanged for, an option with identical terms appropriately adjusted, to
acquire the number and class of shares or other securities or property that the
optionholder would have received under the stock option agreement if the option
had been exercised immediately before the consolidation, merger, or sale, as
applicable.
 
   Cash Payment in Respect of the Option. Under each of the stock option
agreements, the optionholder has the right, at any time after the option has
become exercisable, to elect to receive a cash payment in an amount equal to
the product of:
 
   (x) the difference between:
 
      .  the higher of:
 
                                       76

<PAGE>
 
      .  the highest price per share proposed to be paid by any other
         person in connection with any Acquisition Proposal; and
 
      .  the highest closing price of the stock during the six-month
         period immediately preceding the date on which the optionholder
         gives notice of the election to receive cash; and
 
      .  the exercise price; multiplied by
 
   (y) the number of shares of the issuer's common stock designated by the
optionholder.
 
   Profit Limitations. The Time Warner stock option agreement provides that in
no event will America Online's total profit under the Time Warner stock option
agreement, plus any termination fee paid by Time Warner under the merger
agreement, exceed in the aggregate, an amount equal to 2.75% of the product of:
 
  .  the number of shares of Time Warner's common stock outstanding as of
     January 10, 2000, the date of each stock option agreement (calculated as
     described above for termination fees under the merger agreement);
     multiplied by
 
  .  1.5; multiplied by
 
  .  the last sale price of America Online's common stock on the New York
     Stock Exchange on January 7, 2000.
 
   Similarly, the America Online stock option agreement provides that in no
event will Time Warner's total profit under the America Online stock option
agreement, plus any termination fee paid by America Online under the merger
agreement, exceed in the aggregate an amount equal to 2.75% of the product of:
 
  .  the number of shares of America Online's common stock outstanding as of
     January 10, 2000, the date of each stock option agreement (calculated as
     described above for termination fees under the merger agreement);
     multiplied by
 
  .  the last sale price of America Online's common stock on the New York
     Stock Exchange on January 7, 2000.
 
   If the total profit that would otherwise be received by the optionholder
exceeds the maximum amount permissible, the optionholder must, in its sole
discretion:
 
  .  reduce the number of shares subject to the stock option agreement;
 
  .  deliver to the issuer for cancellation shares previously purchased;
 
  .  reduce the amount to be paid by the optionholder;
 
  .  pay cash to the issuer of the option; or
 
  .  take any combination of these actions, so that its total profit does not
     exceed the maximum amount.
 
   Registration Rights and Listing. Each of the stock option agreements
provides that the optionholder has specified rights to require the issuer to
register, under the Securities Act of 1933 and any applicable state law, all
shares purchased by the optionholder pursuant to the stock option agreement.
Each of the stock option agreements also provides that the optionholder has
specified rights to require that the issuer list the shares purchased by the
optionholder pursuant to the stock option agreement on the New York Stock
Exchange or other national securities exchange or trading system on which
shares of the issuer's common stock are listed for trading or quotation.
 
   Assignability. Neither of the stock option agreements, nor any of the
rights, interests or obligations under them may be assigned by either of the
parties without the prior written consent of the other party.
 
   Effect of Stock Option Agreements. The stock option agreements are intended

option agreements may discourage persons who might be interested in acquiring
all or a significant interest in America Online or Time Warner before
completion of the merger from considering or proposing an acquisition, even if
those persons were prepared to offer higher consideration per share of Time
Warner capital stock or America Online common stock than the consideration
implicit in the merger or a higher price per share of Time Warner common stock
or America Online common stock than the stock market price.
 
Voting Agreement
 
   The following summary of the voting agreement is qualified in its entirety
by reference to the complete text of the voting agreement, which is
incorporated by reference and attached as Annex D to this joint proxy
statement-prospectus. We urge you to read the full text of the voting
agreements.
 
   In connection with the execution and delivery of the merger agreement,
America Online entered into a voting agreement with R.E. Turner, Vice Chairman
of Time Warner, Turner Partners, L.P. and Turner Outdoor, Inc. under which
these principal stockholders agreed to vote substantially all their shares of
Time Warner common stock in favor of the adoption of the merger agreement. As
of the record date for the special meeting, these stockholders owned [   ]
shares of Time Warner common stock, representing approximately [ ]% of the
outstanding shares of Time Warner common stock (and approximately % of the
total voting power of the outstanding shares of Time Warner capital stock).
 
   The voting agreement prohibits, subject to limited exceptions, any
stockholder from selling, transferring, pledging, encumbering, assigning or
otherwise disposing of any shares of Time Warner capital stock, except to a
person who agrees in writing to be bound by the terms of the voting agreement.
The stockholders collectively may sell, transfer, pledge, encumber, assign or
otherwise dispose of an aggregate of up to 5% of the shares of Time Warner
common stock held of record by the stockholders collectively as of January 10,
2000, the date of the voting agreement, without complying with the restrictions
on transfers contained in the voting agreement.
 
   The voting agreement terminates upon the earlier to occur of the completion
of the merger and the termination of the merger agreement in accordance with
its terms.

             PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
 
   The following pro forma consolidated condensed financial statements are
presented to illustrate the effects of the merger on the historical financial
position and operating results of America Online and Time Warner. 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: (1) a June 30 fiscal-year basis,
which is consistent with America Online's historical fiscal year-end and (2) 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.
Management believes 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.
 
   The following pro forma consolidated condensed balance sheet of AOL Time
Warner at September 30, 1999 gives effect to the merger as if it occurred as of
that date. On a June 30 fiscal-year basis, the pro forma consolidated condensed
statements of operations of AOL Time Warner for the three months ended
September 30, 1999 and the year ended June 30, 1999 give effect to the merger
as if it occurred as of July 1, 1998. On a December 31 calendar-year basis, the
pro forma consolidated condensed statements of operations of AOL Time Warner
for the nine months ended September 30, 1999 and the year ended December 31,
1998 give effect to the merger as if it occurred as of January 1, 1998. In
addition, the pro forma consolidated condensed statements of operations of AOL
Time Warner for the years ended June 30, 1999 and December 31, 1998 also give
effect to Time Warner's consolidation of the operating results of the
entertainment group, which were formerly accounted for under the equity method
of accounting, as described more fully in Time Warner's Current Report on Form
8-K dated August 3, 1999, which is incorporated in this joint proxy statement-
prospectus by reference.
 
   The pro forma consolidated condensed financial statements have been derived
from, and should be read in conjunction with, the historical consolidated
financial statements, including the notes thereto, of each of America Online,
Time Warner and TWE. For America Online, those financial statements are
included in America Online's Quarterly Report on Form 10-Q for the quarter
ended September 30, 1999 and its Annual Report on Form 10-K for the year ended
June 30, 1999, which are incorporated in this joint proxy statement-prospectus
by reference, and which have been adjusted for a 2-for-1 common stock split in
November 1999 and the effects of certain business combinations accounted for as
a pooling-of-interests. For Time Warner and TWE, those financial statements are
included in Time Warner's Quarterly Report on Form 10-Q for the quarter ended
September 30, 1999 and Time Warner's Annual Report on Form 10-K for the year
ended December 31, 1998, as amended, which are incorporated in this joint proxy
statement-prospectus by reference.
 
   The pro forma consolidated condensed financial statements are presented for
informational purposes only and are not necessarily indicative of the financial
position or results of operations of AOL Time Warner that would have occurred
had the merger been consummated as of the dates indicated. In addition, the pro
forma consolidated condensed financial statements are not necessarily
indicative of the future financial condition or operating results of AOL Time
Warner.
 
The Merger
 
   The merger will be structured as a stock-for-stock exchange and is described
under the "Merger--Structure of the Merger and Conversion of America Online and
Time Warner Stock."
 
   As a result of the merger, we anticipate that the former stockholders of
America Online will have a 55% interest in AOL Time Warner and that the former
stockholders of Time Warner will have a 45% interest in AOL Time Warner,
expressed on a fully diluted basis. The merger is expected to be accounted for
by AOL Time Warner as an acquisition of Time Warner under the purchase method
of accounting for business combinations.
 
 
                                       79

<PAGE>
 
   Under the purchase method of accounting, the estimated cost of approximately
$146 billion to acquire Time Warner, including transaction costs, will be
allocated to its underlying net assets in proportion to their respective fair
values. Any excess of the purchase price over the estimated fair value of the
net assets acquired will be recorded as goodwill. As more fully described in
the notes to the pro forma consolidated condensed financial statements, a
preliminary allocation of the excess of the purchase price, including
transaction costs, over the book value of the net assets to be acquired has
been made to goodwill and other intangible assets. The work needed to provide
the basis for estimating these fair values has not been completed. As a result,
the final allocation of the excess of purchase price over the book value of the
net assets acquired could differ materially from the preliminary allocation.
 
   Pro forma adjustments for the merger include:
 
  .  the issuance of approximately 1.9 billion shares of AOL Time Warner
     common stock and AOL Time Warner series LMCN-V common stock in exchange
     for all of the 1.3 billion outstanding shares of Time Warner common
     stock and series LMCN-V common stock;
 
  .  the issuance of approximately 8.4 million shares of AOL Time Warner
     preferred stock in exchange for all of the 8.4 million outstanding
     shares of Time Warner preferred stock;
 
  .  the issuance of options to purchase approximately 209 million shares of
     AOL Time Warner common stock in exchange for all of the outstanding
     options to purchase 139 million shares of Time Warner common stock; and
 
  .  the incurrence of approximately $300 million of transaction costs by
     America Online and Time Warner, including legal, investment banking and
     registration fees.
 
   No pro forma adjustments are necessary to reflect the merger of America
Online into a separate wholly owned subsidiary of AOL Time Warner because
America Online's net assets will be recorded at their historical cost basis and
the exchange ratio for America Online common stock is one to one. America
Online agreed to acquire MapQuest.com, Inc. and Time Warner has agreed to form
a global music joint venture with EMI Group. Because these transactions are not
significant to the consolidated condensed balance sheet of AOL Time Warner or
to pro forma net income of AOL Time Warner for any of the periods presented in
this joint proxy statement-prospectus, they have not been reflected in these
pro forma financial statements.

          NOTES TO THE PRO FORMA CONSOLIDATED CONDENSED BALANCE SHEET
                                  (unaudited)
 
(a) Reflects the historical financial position of America Online at September
    30, 1999. America Online's historical common stock and paid-in capital as
    of September 30, 1999 have been restated to reflect the effect of a 2-for-1
    common stock split that occurred in November 1999.
 
(b) Reflects the historical financial position of Time Warner at September 30,
    1999.
 
(c) Pro forma adjustments to record the merger as of September 30, 1999
    reflect:
 
  .  an increase in equity of $130.758 billion relating to the issuance of
     1.930 billion shares of AOL Time Warner common stock (including the
     issuance of 171.2 million shares relating to the conversion of 114.1
     million outstanding shares of Time Warner's series LMCN-V common stock
     into an identical class of AOL Time Warner series LMCN-V common stock),
     $0.01 par value per share, in exchange for approximately 1.287 billion
     outstanding shares of Time Warner common stock, based on an exchange
     ratio of 1.5 to 1. The AOL Time Warner common stock to be issued was
     valued based on a price per share of $67.75, which is the average market
     price of the America Online common stock for a few days before and after
     the date the merger was announced;
 
  .  an increase in equity of $3.557 billion relating to the issuance of
     approximately 8.404 million shares of AOL Time Warner preferred stock,
     $0.10 par value per share, in exchange for all outstanding shares of
     Time Warner preferred stock. The shares of AOL Time Warner preferred
     stock to be issued, which will each be convertible into 6.24792 shares
     of AOL Time Warner common stock, were valued based on their common
     equivalent value of $423.30 per share;
 
  .  an increase in equity of $11.636 billion relating to the issuance of
     options to purchase 208.455 million shares of AOL Time Warner common
     stock in exchange for all of the 138.970 million outstanding options to
     purchase shares of Time Warner common stock, based on a value per common
     share of $55.82, calculated using the Black-Scholes option pricing
     model;
 
  .  an increase in accrued expenses of approximately $300 million relating
     to the incurrence of transaction costs by America Online and Time
     Warner, including legal, investment banking and registration fees;
 
  .  the elimination of approximately $15.377 billion of Time Warner's pre-
     existing goodwill;
 
  .  the preliminary allocation of the excess of the $146.251 billion
     purchase price, including transaction costs, over the book value of the
     net assets acquired to (i) goodwill in the amount of $95.842 billion,
     (ii) other intangible assets in the amount of $95 billion and (iii)
     deferred income taxes in the amount of $38 billion. The final allocation
     of the purchase price will be determined after the completion of the
     merger and will be based on a comprehensive final evaluation of the fair
     value of Time Warner's tangible and identifiable intangible assets
     acquired and liabilities assumed at the time of the merger;
 
  .  a reduction of $3.024 billion in deferred income tax liabilities and a
     corresponding increase in paid-in capital relating to the elimination of
     America Online's deferred tax valuation allowance against stock option-
     related tax benefits that will become realizable as a direct result of
     the merger; and
 
  .  a decrease in stockholders' equity of $8.786 billion relating to the
     elimination of Time Warner's historical shareholders' equity.

(d) Reflects the historical operating results of America Online for the three
    months ended September 30, 1999 and the year ended June 30, 1999.
    Outstanding share and per share information for America Online have been
    restated to reflect a 2-for-1 common stock split which occurred in November
    1999. Finally, various reclassifications have been made to conform to AOL
    Time Warner's combined financial statement presentation.
 
(e) Reflects the historical operating results of Time Warner for the three
    months ended September 30, 1999, including various reclassifications that
    have been made to conform to AOL Time Warner's combined financial
    statements presentation.
 
(f) Pro forma adjustments to record the merger for the three months ended
    September 30, 1999 and the year ended June 30, 1999 reflect:
 
  .  increases of $1.908 billion and $7.634 billion, respectively, in
     amortization of goodwill and other intangible assets relating to the
     amortization of the excess of the purchase price to acquire Time Warner
     over the book value of its net assets acquired, which has been allocated
     to goodwill and other intangible assets, and are each amortized on a
     straight-line basis over a twenty-five-year weighted-average period;
 
  .  decreases of $132 million and $533 million, respectively, in
     amortization of goodwill and other intangible assets relating to the
     elimination of Time Warner's amortization of pre-existing goodwill;
 
  .  increases of $380 million and $1.520 billion, respectively, in income
     tax benefits, provided at a 40% tax rate, on the aggregate pro forma
     reduction in pretax income before goodwill amortization; and
 
In addition, pro forma net income (loss) per common share has been adjusted to
reflect the issuance of additional shares of AOL Time Warner common stock in
the merger, based on Time Warner's historical weighted average shares
outstanding for the periods presented and an exchange ratio of 1.5 to 1.
Because the effect of stock options and other convertible securities would be
antidilutive to AOL Time Warner, dilutive per share amounts on a pro forma
basis are the same as basic per share amounts.
 
(g) Reflects the historical operating results of Time Warner for the year ended
    June 30, 1999, as adjusted to reflect Time Warner's consolidation for all
    periods prior to 1999. In order to conform Time Warner's fiscal year-end
    from a calendar year basis to America Online's June 30 year-end, Time
    Warner's historical operating results have been derived from the
    combination of Time Warner's quarterly historical operating results for the
    year ended June 30, 1999. In addition, as shown in the following
    reconciliation, Time Warner's historical operating results for this period
    have been adjusted to reflect Time Warner's consolidation of the
    entertainment group for the six-month period ended December 31, 1998.
    During this period, Time Warner accounted for the entertainment group under
    the equity method of accounting. A complete description of Time Warner's
    consolidation of the entertainment group, and the nature of the pro forma
    adjustments is in Time Warner's Current Report on Form 8-K dated August 3,
    1999, which is incorporated by reference in this joint proxy statement-
    prospectus.

    entertainment group, as of and for the six months ended December 31, 1998.
    Various reclassifications have been made to conform to the new,
    consolidated presentation.
(2) Adjustments reflect the elimination of all significant intercompany
    accounts and transactions between Time Warner and the entertainment group
    and other consolidating adjustments necessary to prepare a consolidated set
    of financial statements.
(3) As filed in Time Warner's Current Report on Form 8-K, dated August 3, 1999.
(4) Per common share amounts for the six-month period and full year have been
    calculated separately. Accordingly, per share amounts for the six-month
    periods do not add to the annual amount because of differences in the
    average common shares outstanding during each period.

    NOTES TO THE PRO FORMA CONSOLIDATED CONDENSED STATEMENTS OF OPERATIONS--
                                  (Continued)
                                  (unaudited)
 
(h) Reflects the historical operating results of America Online for the nine
    months ended September 30, 1999 and the year ended December 31, 1998. In
    order to conform America Online's fiscal year end of June 30 to a calendar-
    year basis, these operating results have been derived from the combination
    of America Online's quarterly historical operating results for these
    periods. In addition, outstanding share and per share information for
    America Online has been restated to reflect a 2-for-1 common stock split
    which occurred in November 1999. Finally, various reclassifications have
    been made to conform to AOL Time Warner's combined financial statement
    presentation.
 
(i) Reflects the historical operating results of Time Warner for the nine
    months ended September 30, 1999, including various reclassifications that
    have been made to conform to AOL Time Warner's combined financial statement
    presentation.
 
(j) Pro forma adjustments to record the merger for the nine months ended
    September 30, 1999 and the year ended December 31, 1998 reflect:
 
  .  increases of $5.725 billion and $7.634 billion, respectively, in
     amortization of goodwill and other intangible assets relating to the
     amortization of the excess of the purchase price to acquire Time Warner
     over the book value of its net assets acquired, which has been allocated
     to goodwill and other intangible assets and are each amortized on a
     straight-line basis over a twenty-five year weighted-average period;
 
  .  decreases of $398 million and $532 million, respectively, in
     amortization of goodwill and other intangible assets relating to the
     elimination of Time Warner's amortization of pre-existing goodwill; and
 
  .  increases of $1.140 billion and $1.520 billion, respectively, in income
     tax benefits, provided at a 40% tax rate, on the aggregate pro forma
     reduction in pretax income before goodwill amortization.
 
  In addition, pro forma net income (loss) per common share has been adjusted
  to reflect the issuance of additional shares of AOL Time Warner common
  stock in the merger, based on Time Warner's historical weighted average
  shares outstanding for the periods presented and an exchange ratio of 1.5
  to 1. Because the effect of stock options and other convertible securities
  would be antidilutive to AOL Time Warner, dilutive per share amounts on a
  pro forma basis are the same as basic per share amounts.
 
(k) Reflects the pro forma operating results of Time Warner for the year ended
    December 31, 1998 giving effect to the consolidation of the entertainment
    group, which were formerly accounted for under the equity method of
    accounting, as described more fully in Time Warner's Current Report on Form
    8-K dated August 3, 1999.
 
(l) Pro forma EBITDA for AOL Time Warner includes a number of significant and
    nonrecurring items. The aggregate effect of those items for each period, as
    well as the adjusted EBITDA excluding such amounts, is as follows:

(m) EBITDA consists of business segment operating income (loss) before
    depreciation and amortization. AOL Time Warner considers EBITDA 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 performance
    of AOL Time Warner, 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. This definition of EBITDA
    may not be comparable to similarly titled measures reported by other
    companies.

   Holders of AOL Time Warner series LMC common stock will be entitled to vote
on all matters on which holders of AOL Time Warner common stock will be
entitled to vote. Holders of AOL Time Warner series LMC common stock will vote
together as a single class with holders of AOL Time Warner common stock and any
other class or series of AOL Time Warner capital stock that is entitled to vote
with the AOL Time Warner common stock. A vote of at least two-thirds of the
voting power of all shares of AOL Time Warner series LMC common stock that are
outstanding will be necessary in order to amend, alter or repeal any of the
provisions of the AOL Time Warner restated certificate of incorporation,
including the certificate of designations relating to the AOL Time Warner
series LMC common stock, to:
 
  .  amend, alter or repeal any of the powers, preferences or rights of the
     AOL Time Warner series LMC common stock or series LMCN-V common stock;
     or
 
  .  adversely affect the voting powers, designations, preferences and
     relative, participating, optional or other special rights, and
     qualifications, limitations or restrictions, of the AOL Time Warner
     series LMC common stock or series LMCN-V common stock.
 
   In addition, the affirmative vote of holders of shares of AOL Time Warner
series LMC common stock representing 100% of the aggregate voting power of the
outstanding shares of AOL Time Warner series LMC common stock is required to
amend, alter or repeal the provisions of the certificate of designations that
prohibit AOL Time Warner from, at its option, redeeming the shares of AOL Time
Warner series LMC common stock.
 
   The vote of the holders of shares of AOL Time Warner series LMC common stock
will not be required for AOL Time Warner to:
 
    .  create any indebtedness;
 
    .  authorize or issue any class of capital stock that is senior to, or
       on a parity with, AOL Time Warner series LMC common stock with
       respect to the payment of dividends or any other distribution of
       assets;
 
    .  approve any amendment to the AOL Time Warner restated certificate of

       of authorized shares of AOL Time Warner series common stock or AOL
       Time Warner common stock; or
 
    .  authorize any increase or decrease in the number of shares
       constituting the AOL Time Warner series LMC common stock.
 
   Cash Dividends. Holders of AOL Time Warner series LMC common stock will be
entitled to receive cash dividends when and if declared by the AOL Time Warner
board of directors, but only to the extent that regularly scheduled cash
dividends are declared and paid on AOL Time Warner common stock. When declared,
cash dividends on each share of AOL Time Warner series LMC common stock will
equal the product of:
 
    .  the amount of the regularly scheduled cash dividend to be paid on
       one share of AOL Time Warner common stock; multiplied by
 
    .  the LMC formula number in effect on the dividend payment date.
 
   Distributions. If AOL Time Warner distributes to the holders of its common
stock any assets or property, in each case not including a distribution upon
the liquidation of AOL Time Warner, a regularly scheduled cash dividend or a
common stock dividend that results in an adjustment of the LMC formula number,
then AOL Time Warner must at the same time distribute the same assets or
property pro rata to the holders of AOL Time Warner series LMC common stock in
an amount equal to the amount that the holders of AOL Time Warner series LMC
common stock would have been entitled to receive had they converted their
shares of AOL Time Warner series LMC common stock into shares of AOL Time
Warner common stock immediately prior to the record date for the distribution.

<PAGE>
 
   Conversion Rights. Holders of AOL Time Warner series LMC common stock will
have the right to convert each of their shares, at any time, into:
 
    .  a number of shares of AOL Time Warner common stock equal to the LMC
       formula number; or
 
    .  one share of AOL Time Warner series LMCN-V common stock.
 
   Each holder of AOL Time Warner series LMC common stock may convert shares of
AOL Time Warner series LMC common stock into shares of AOL Time Warner common
stock or AOL Time Warner series LMCN-V common stock only to the extent that the
ownership by the converting holder of shares of AOL Time Warner common stock or
AOL Time Warner series LMCN-V common stock upon conversion would not violate
the federal communications laws.
 
   Conversion Rate Adjustment. If AOL Time Warner consolidates or merges with
another entity such that AOL Time Warner is not the surviving entity or the
transaction results in a change in AOL Time Warner common stock, or if AOL Time
Warner sells all or substantially all of its property and assets to another
entity, each share of AOL Time Warner series LMC common stock will be
convertible into the number of shares of capital stock or other property
received by the holder of a number of shares of AOL Time Warner common stock
into which the shares of AOL Time Warner series LMC common stock could have
been converted immediately before the transaction.
 
   Liquidation Rights. In the event of the liquidation of AOL Time Warner, the
holders of AOL Time Warner series LMC common stock will be entitled to receive,
at the same time as any distribution to holders of AOL Time Warner common
stock, an aggregate amount per share equal to the product of:
 
  .  the aggregate amount to be distributed per share to holders of AOL Time
     Warner common stock; and
 
  .  the LMC formula number in effect on the date of the distribution.
 
   Transfer Restriction. Holders of AOL Time Warner series LMC common stock
will be subject to a transfer restriction that prevents these holders, without
obtaining prior consent from AOL Time Warner, from transferring their shares of
AOL Time Warner series LMC common stock to any person other than a "permitted
transferee." The term "permitted transferee" means:
 
  .  Liberty Media Corporation, which is commonly referred to as "LMC," and
     any affiliate that is controlled by LMC; or
 
  .  Tele-Communications Inc. and any affiliate that is controlled by Tele-
     Communications, so long as Tele-Communications is an affiliate of LMC.
 
In addition, the transfer restriction provides that any permitted transferee
must agree to be subject to the transfer restriction for subsequent transfers.
 
   The transfer restriction applicable to AOL Time Warner series LMC common
stock will not prevent any holder of AOL Time Warner series LMC common stock
from:
 
    .  entering into an arrangement providing for the transfer or sale of
       any AOL Time Warner common stock received immediately upon the
       conversion of shares of AOL Time Warner series LMC common stock; or
 
    .  pledging shares of AOL Time Warner series LMC common stock, so long
       as the terms of the pledge provide that, in the event of a
       foreclosure on the shares of AOL Time Warner series LMC common
       stock, the foreclosing party will deliver the forfeited AOL Time
       Warner series LMC common stock to AOL Time Warner for conversion
       into AOL Time Warner common stock.
 
 
                                       93

<PAGE>
 
Series LMCN-V Common Stock
 
   LMCN-V Formula Number. Shares of AOL Time Warner series LMCN-V common stock
will be attributed a formula number that will be used to calculate the
dividend, voting, conversion and liquidation rights for each share of AOL Time
Warner series LMCN-V common stock. We refer to this formula number as the
"LMCN-V formula number." The LMCN-V formula number will be initially set at
1.00, and will be subject to adjustment for stock splits, reverse stock splits,
stock dividends and other similar corporate events affecting the AOL Time
Warner common stock.
 
   Voting Rights. Holders of AOL Time Warner series LMCN-V common stock will be
entitled to vote together as a single class with the holders of AOL Time Warner
common stock and any other class or series of AOL Time Warner capital stock
that is entitled to vote with the AOL Time Warner common stock in the election
of directors of AOL Time Warner, and they will have the right to cast a number
of votes per share that is equal to:
 
  .  the product of the number of votes per share that may be cast by holders
     of AOL Time Warner common stock multiplied by the LMCN-V formula number
     in effect at the time of the vote; divided by
 
  .  100.
 
   A vote of at least two-thirds of the voting power of all shares of AOL Time
Warner series LMCN-V common stock that are outstanding will be necessary in
order to amend, alter or repeal any of the provisions of the AOL Time Warner
restated certificate of incorporation, including the certificate of
designations relating to the AOL Time Warner series LMCN-V common stock, to:
 
  .  amend, alter or repeal any of the powers, preferences or rights of the
     AOL Time Warner series LMC common stock or series LMCN-V common stock;
     or
 
  .  adversely affect the voting powers, designations, preferences and
     relative, participating, optional or other special rights, and
     qualifications, limitations or restrictions, of the AOL Time Warner
     series LMCN-V common stock or series LMC common stock.

             COMPARISON OF RIGHTS OF AOL TIME WARNER STOCKHOLDERS,
            AMERICA ONLINE STOCKHOLDERS AND TIME WARNER STOCKHOLDERS
 
   AOL Time Warner, America Online and Time Warner are all organized under the
laws of the State of Delaware. Any differences, therefore, in the rights of
holders of AOL Time Warner capital stock, America Online capital stock and Time
Warner capital stock arise primarily from differences in their respective
restated certificates of incorporation, restated by-laws and rights agreements.
Upon completion of the merger, holders of America Online common stock and
holders of Time Warner capital stock will become holders of AOL Time Warner
capital stock and their rights will be governed by Delaware law, the AOL Time
Warner restated certificate of incorporation and the AOL Time Warner restated
by-laws.
 
   This section of the proxy statement-prospectus describes the material
differences between the rights of America Online stockholders and Time Warner
stockholders. This section also includes a brief description of the material
rights that AOL Time Warner stockholders are expected to have following
completion of the merger although in some cases the board of directors of AOL
Time Warner retains the discretion to alter those rights without stockholder
consent. 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. All America Online stockholders and
Time Warner stockholders are urged to read carefully the relevant provisions of
Delaware law, as well as the restated certificates of incorporation and
restated by-laws of each of America Online, Time Warner and AOL Time Warner.
Copies of the forms of restated certificate of incorporation and restated by-
laws for AOL Time Warner are attached to this joint proxy statement-prospectus
as Annexes G and H, respectively. Copies of the restated certificates of

Limitation of Personal Liability of Directors and Officers
 
   General. Delaware law provides that a corporation may include in its

of its directors to the corporation and its stockholders for monetary damages
arising from a breach of fiduciary duty, except for:

                                      112

be liable to America Online or its stockholders for monetary damages for breach
of fiduciary duty as a director.
 
   Time Warner. The Time Warner restated certificate of incorporation provides
that, to the fullest extent Delaware law permits the limitation or elimination
of the liability of directors, no director of Time Warner will be liable to

duty as a director.
 
   AOL Time Warner. The AOL Time Warner restated certificate of incorporation

Indemnification of Directors and Officers
 
   General. Under Delaware law, a corporation may indemnify directors and
officers:
 
  .  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 proceeding, they had no reasonable cause to
     believe that their conduct 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.
 
   America Online. The America Online restated certificate of incorporation and
restated by-laws provide that any person who was or is 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 or
officer, or is or was serving at the request of America Online 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 America Online to the fullest

certificate of incorporation or restated by-laws, any agreement, vote of
stockholders or disinterested directors or otherwise. In addition, America
Online is authorized to purchase and maintain insurance on behalf of its
directors and officers.
 
   In addition, America Online may pay expenses incurred by its directors and
officers in defending a civil or criminal action, suit or proceeding because
they are directors or officers in advance of the final disposition of the
action, suit or proceeding. The payment of expenses will be made only if
America Online receives an undertaking by or on behalf of the director or
officer receiving the payment to repay all amounts advanced if it is ultimately
determined that the director or officer is not entitled to be indemnified by
America Online, as authorized by America Online's restated certificate of
incorporation and restated by-laws.
 
   Time Warner. The Time Warner by-laws provide for indemnification, to the
fullest extent permitted by Delaware law, of any person who is or was a
director or officer of Time Warner and who is or was involved in
 
                                      113

<PAGE>
 
any manner, or who is threatened to be made involved in any manner, in any
pending or completed proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he or she is or was a director,
officer, employee or agent of Time Warner, or is or was serving at the request
of Time Warner as a director, officer, employee or agent of another
corporation, or of a partnership, joint venture, trust or other enterprise,
against all expenses actually and reasonably incurred, although no
indemnification is available to a director or officer with respect to a
proceeding that was commenced by the director or officer unless the proceeding
was commenced after a "change of control." The Time Warner by-laws define
"change of control" as the occurrence of:
 
  .  a merger or consolidation of Time Warner in which Time Warner is not the
     surviving or continuing corporation or pursuant to which shares of Time
     Warner common stock are converted into cash, securities or other
     property, other than a merger of Time Warner in which the holders of
     Time Warner common stock immediately prior to the merger have the same
     proportionate ownership of common stock of the surviving or continuing
     corporation;
 
  .  any sale, lease, exchange or other transfer of all or substantially all
     of the assets of Time Warner, or the liquidation or dissolution of Time
     Warner;
 
  .  any person becomes an "interested stockholder" without the prior consent
     of the Time Warner board of directors; or
 
  .  during any period of two consecutive years, individuals who at the
     beginning of the two-year period constituted a majority of the Time
     Warner board of directors have ceased for any reason to constitute a
     majority of the Time Warner board of directors unless the election or
     nomination of each of the new directors was approved by a vote of at
     least two-thirds of the directors then still in office who were
     directors at the beginning of the two-year period.
 
   In addition, the Time Warner by-laws provide that all reasonable expenses
incurred by or on behalf of a director or officer in connection with any
investigation, claim, action, suit or proceeding will be advanced to the
director or officer by Time Warner upon the request of the director or officer
which request, if required by law, will include an undertaking by or on behalf
of the director or officer to repay the amounts advanced if ultimately it is
determined that the director or officer was not entitled to be indemnified
against the expenses.
 
   AOL Time Warner. The AOL Time Warner restated by-laws will provide for
indemnification, to the fullest extent permitted by Delaware law, of any person
who is or was a director or officer of AOL Time Warner and who is or was
involved in any manner, or who is threatened to be made involved in any manner,
in any pending or completed proceeding, whether civil, criminal, administrative
or investigative, by reason of the fact that he or she is or was a director,
officer, employee or agent of AOL Time Warner, or is or was serving at the
request of AOL Time Warner as a director, officer, employee or agent of another
corporation, or of a partnership, joint venture, trust or other enterprise,
against all expenses actually and reasonably incurred, although no
indemnification is available to a director or officer with respect to a
proceeding that was commenced by the director or officer unless the proceeding
was commenced after a "change of control." The AOL Time Warner restated by-laws
will define "change of control" as the occurrence of:
 
  .  a merger or consolidation of AOL Time Warner in which AOL Time Warner is
     not the surviving or continuing corporation or pursuant to which shares
     of AOL Time Warner common stock are converted into cash, securities or
     other property, other than a merger of AOL Time Warner in which the
     holders of AOL Time Warner common stock immediately prior to the merger
     have the same proportionate ownership of common stock of the surviving
     or continuing corporation;
 
  .  any sale, lease, exchange or other transfer of all or substantially all
     of the assets of AOL Time Warner, or the liquidation or dissolution of
     AOL Time Warner; or
 
 
                                      114

<PAGE>
 
  .  during any period of two consecutive years, individuals who at the
     beginning of the two-year period constituted a majority of the AOL Time
     Warner board of directors have ceased for any reason to constitute a
     majority of the AOL Time Warner board of directors unless the election
     or nomination of each of the new directors was approved by a vote of at
     least two-thirds of the directors then still in office who were
     directors at the beginning of the two-year period.
 
   In addition, the AOL Time Warner restated by-laws will provide that all
reasonable expenses incurred by or on behalf of a director or officer in
connection with any investigation, claim, action, suit or proceeding will be
advanced to the director or officer by AOL Time Warner upon the request of the
director or officer which request, if required by law, will include an
undertaking by or on behalf of the director or officer to repay the amounts
advanced if ultimately it is determined that the director or officer was not
entitled to be indemnified against the expenses.
 
Stockholders Rights Plans
 
   America Online. 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 agreement.
The summary does not include a complete description of all of the terms of the
rights agreement. All America Online stockholders and Time Warner stockholders
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 antidilution adjustments in the
event of a stock split, stock dividend or similar transaction with respect to
America Online series A-1 preferred stock.
 
   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 AOL common stock then
     outstanding;
 
  .  ten days following the public disclosure of facts indicating 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 merger, 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
related transactions.
 
   "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
 
                                      115

<PAGE>
 
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;
 
  .  an acquiring 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 America
Online right, the number of shares of the acquiring company's capital stock
with the greatest voting power 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:
 
  .  public disclosure 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, as described under "Rights Plan-
Exercisability of 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 or group 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 since America Online may redeem the America Online rights as and
since a
 
                                      116

<PAGE>
 
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.
 
   Time Warner. In 1996, Time Warner adopted a stockholder rights plan pursuant
to a rights agreement with ChaseMellon Shareholder Services L.L.C., as rights
agent. Set forth below is a summary of the material provisions of the rights
agreement. The summary does not include a complete description of all of the
terms of the rights agreement. All Time Warner stockholders and America Online
stockholders are urged to read carefully the relevant provisions of Time
Warner's rights plan, copies of which will be sent to Time Warner stockholders
upon request. See "Where you can find more information."
 
   Exercisability of Rights. Under the Time Warner rights agreement, one right,
referred to as a Time Warner right, attaches to each share of Time Warner
common stock outstanding and, when exercisable, entitles the registered holder
to purchase from Time Warner one two-thousandth of a share of Time Warner
series A preferred stock at an initial purchase price of $75, subject to
customary antidilution adjustments.
 
   The Time Warner rights will not become exercisable until the earlier of:
 
  .  such time as Time Warner learns that a person has become the beneficial
     owner of 15% or more of the outstanding Time Warner common stock; and
 
  .  the close of business on the date following the commencement of, or the
     announcement of an intention to commence, a tender offer or exchange
     offer that would result in a person or group becoming the beneficial
     owner of 15% or more of the outstanding Time Warner common stock.
 
In connection with the merger, the Time Warner rights agreement was amended to
provide that the Time Warner rights will not become exercisable solely by
reason of the merger agreement, the stock option agreement and the related
transactions.
 
   "Flip In" Feature. In the event a person becomes the beneficial owner of 15%
or more of the outstanding Time Warner common stock, each holder of a Time
Warner right, except for such person, will have the right to acquire, upon
exercise of the Time Warner right, instead of one two-thousandth of a share of
Time Warner series A preferred stock, shares of Time Warner common stock having
a value equal to twice the exercise price of the Time Warner right. For
example, if we assume that the initial purchase price of $75 is in effect on
the date that the flip-in feature of the Time Warner right is exercised, any
holder of a Time Warner right, except for the person that has become the
beneficial owner of 15% or more of the outstanding Time Warner common stock,
can exercise his or her Time Warner right by paying to Time Warner $75 in order
to receive from Time Warner shares of Time Warner common stock having a value
equal to $150.
 
   "Exchange" Feature. At any time after a person becomes the beneficial owner
of 15% or more of the outstanding Time Warner common stock, the board of
directors of Time Warner may, at its option, exchange all or some of the Time
Warner rights, except for those held by such person or group, for Time Warner
common
 
                                      117

<PAGE>
 
stock at an exchange ratio of one share of Time Warner common stock per Time
Warner right, subject to adjustment, and cash instead of fractional shares, if
any. Use of this exchange feature means that eligible Time Warner rights
holders would not have to pay a purchase price before receiving shares of Time
Warner common stock.
 
   "Flip Over" Feature. In the event that, after a corporate entity acquires
15% or more of Time Warner common stock then outstanding:
 
  .  Time Warner consolidates with or merges into the acquiring entity;
 
  .  the acquiring entity merges into Time Warner; or
 
  .  Time Warner sells more than 50% of its assets or earning power,
 
then each holder of a Time Warner right, except for a person that is the
beneficial owner of 15% or more of the Time Warner common stock then
outstanding, will have the right to receive, upon exercise of the Time Warner
right, the number of shares of the acquiring company's capital stock with the
greatest voting power having a value equal to twice the exercise price of the
Time Warner right.
 
   Redemption of Rights. At any time prior to the earlier to occur of:
 
  .  a person becoming the beneficial owner of securities representing 15% or
     more of the outstanding Time Warner common stock; and
 
  .  January 20, 2004,
 
the board of directors of Time Warner may redeem all of the Time Warner rights
at a redemption price of $0.005 per right, subject to adjustment. The right to
exercise the Time Warner right will terminate upon redemption, and at such
time, the holders of the Time Warner rights will have the right to receive only
the redemption price for each Time Warner right held.
 
   Amendment of Rights. At any time before a person becomes the beneficial
owner of 15% or more of the outstanding Time Warner common stock, the terms of
the existing Time Warner rights agreement may be amended by the Time Warner
board of directors without the approval of the holders of the rights. After the
date any person acquires at least 15% of Time Warner's common stock, however,
the rights agreement may not be amended in any manner which would adversely
affect the interests of the holders of the Time Warner rights, excluding the
interests of the acquiror.
 
   Termination of Rights. If not previously exercised, the Time Warner rights
will expire on January 20, 2004, unless Time Warner earlier redeems or
exchanges the Time Warner rights or shortens or extends the final expiration
date.
 
   Anti-Takeover Effects. The Time Warner rights have anti-takeover effects.
Once the Time Warner rights have become exercisable, the Time Warner rights
will cause substantial dilution to a person or group that attempts to acquire
or merge with Time Warner in most cases. Accordingly, the existence of the Time
Warner rights may deter potential acquirors from making a takeover proposal or
a tender offer. The Time Warner rights should not interfere with any merger or
other business combination approved by the Time Warner board of directors since
Time Warner may redeem the Time Warner rights as described above and since a
transaction approved by the Time Warner board of directors would not cause the
Time Warner rights to become exercisable.
 
   Series A Preferred Stock. In connection with the creation of the Time Warner
rights, the board of directors of Time Warner authorized the issuance of
8,000,000 shares of Time Warner preferred stock as Time Warner series A
participating cumulative preferred stock.
 
   The Time Warner series A preferred is attributed a formula number, referred
to as the "series A formula number," which is currently set at 2,000, is
subject to customary antidilution protections.
 
                                      118

<PAGE>
 
   Time Warner has designed the dividend, liquidation, voting and redemption
features of the Time Warner series A preferred stock so that the value of one
two-thousandths of a share of Time Warner series A preferred stock approximates
the value of one share of Time Warner common stock. Shares of Time Warner
series A preferred stock may only be purchased after the Time Warner rights
have become exercisable.
 
   AOL Time Warner. AOL Time Warner does not intend to have a stockholder
rights plan.
 
State Anti-Takeover Statutes
 
   General. 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 became an affiliate or associate 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 restated 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.
 
   America Online. America Online has not adopted any provision in its restated
certificate of incorporation to "opt-out" of Section 203 and therefore, Section
203 applies to America Online.
 
   Time Warner. Because Time Warner has not adopted any provision in its
restated certificate of incorporation to "opt-out" of the Delaware business
combination statute, the statute is applicable to business combinations
involving Time Warner.
 
   AOL Time Warner. Because the AOL Time Warner restated certificate of
incorporation will not include any provision to "opt-out" of the Delaware
business combination statute, the statute will apply to business combinations
involving AOL Time Warner.
 
Fair Price Provisions
 
   America Online. America Online's certificate of incorporation contains a
"fair price" provision which states that certain "business combinations" with
any "interested stockholder" may not be completed without
 
                                      119

<PAGE>
 
an affirmative vote of the holders of at least 80% of the votes entitled to be
cast by holders of outstanding shares of voting stock of America Online, voting
together as a single class, in addition to any other vote required by America
Online's 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 certificate of incorporation, are met.
 
   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 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
 
                                      120

<PAGE>
 
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.
 
   Time Warner. Time Warner's restated certificate of incorporation contains a
"fair price" provision which states that certain "business combinations"
(including mergers, sales of all or substantially all the assets, the adoption
of a plan of liquidation or similar extraordinary corporate transactions) with
any "interested stockholder" may not be completed without:
 
  .  the affirmative vote of the holders of at least 80% of the votes
     entitled to be cast by holders of shares of stock of Time Warner; and
 
  .  the affirmative vote of the holders of a majority of the votes entitled
     to be cast by holders of shares of stock of Time Warner not affiliated
     with the interested stockholder; or
 
  .  the affirmative vote of the holders of all of the shares of Time Warner
     stock outstanding at the time of approval.
 
   This fair price provision does not apply if:
 
  .  the business combination will have been approved by a majority of the
     directors of Time Warner who are not affiliated with the interested
     stockholder, and the interested stockholder became an interested
     stockholder in a manner approved by the board of directors of Time
     Warner;
 
  .  in the case of certain mergers or consolidations of Time Warner or
     reclassification of securities of Time Warner, the business combination
     will have been approved by a majority of the directors of Time Warner
     who are not affiliated with the interested stockholder, the business
     combination does not result in an increase of more than 10% in the
     amount of equity securities of any class or series of Time Warner or any
     subsidiary of Time Warner beneficially owned by an interested
     stockholder at the time of the approval and the business combination is
     not consummated within two years of the consummation of any other
     business combination in which the proportionate share of equity
     securities of any class or series of Time Warner or any subsidiary of
     Time Warner beneficially owned by the interested stockholder was
     increased;
 
  .  in the case of certain sales of assets by Time Warner or issuances or
     transfers of securities by Time Warner, the business combination will
     have been approved by a majority of the directors of Time Warner not
     affiliated with the interested stockholder; or
 
  .  certain minimum price, form of consideration and procedural requirements
     are met.
 
   Time Warner's fair price provision defines an "interested stockholder" as
any person who or which:
 
  .  is the beneficial owner, directly or indirectly, of 20% or more of the
     combined voting power of the then outstanding shares of Time Warner
     voting stock;
 
  .  is an affiliate of Time Warner and at any time within the two-year
     period immediately prior to the date in question was the beneficial
     owner, directly or indirectly, of 20% or more of the combined voting
     power of the then outstanding shares of Time Warner voting stock; or
 
  .  is an assignee or has otherwise succeeded to the beneficial ownership of
     any shares of Time Warner voting stock which at any time within the two-
     year period immediately prior to the date in question beneficially owned
     by an interested stockholder, if the assignment or succession did not
     occur as part of an initial public offering.
 
   AOL Time Warner. The restated certificate of incorporation of AOL Time
Warner will not contain a provision similar to the fair price provision that is
contained in America Online's or Time Warner's certificates of incorporation.

Board of Directors of AOL Time Warner
 
   Members of the AOL Time Warner Board of Directors. Upon completion of the
merger, the board of directors of AOL Time Warner will be comprised of sixteen
individuals, eight of whom will be designated by America Online and eight of
whom will be designated by Time Warner.
 
   A majority of the members of the board of directors of AOL Time Warner must
be determined by the board of directors of AOL Time Warner to be eligible to be
classified as independent directors. Four of America Online's designees must be
independent and five of Time Warner's designees must be independent. In its
determination of a director's eligibility to be classified as an independent
director, the AOL Time Warner board of directors will consider, among such
other factors as it may in any case deem relevant, that the director:
 
  .  has not been employed by AOL Time Warner as an executive officer within
     the past three years;
 
  .  is not a paid adviser or consultant to AOL Time Warner and derives no
     material financial benefit from any entity as a result of advice or
     consultancy provided to AOL Time Warner by that entity;
 
  .  is not an executive officer, director or significant stockholder of a
     significant customer or supplier of AOL Time Warner;
 
  .  has no personal services contract with AOL Time Warner;
 
  .  is not an executive officer or director of a tax-exempt entity receiving
     a significant part of its annual contributions from AOL Time Warner;
 
  .  is not a member of the immediate family of any director who is not
     considered an independent director; and
 
  .  is free of any other relationship that would interfere with the exercise
     of independent judgment by the director.
 
   The affirmative vote of 75% of the members of the board of directors of AOL
Time Warner will be required to change the size of the AOL Time Warner board of
directors.
 
   To date, America Online and Time Warner have designated the following
individuals to be directors of AOL Time Warner upon completion of the merger:

                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 joint 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 joint proxy statement-prospectus
referring to America Online, Time Warner and AOL Time Warner, and they may also
be made a part of this joint proxy statement-prospectus by reference to other
documents filed with the Securities and Exchange Commission by America Online
and Time Warner, 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," "expects," "projects," "intends,"
"plans," "believes" 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 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 the businesses of
America Online and Time Warner, the factors relating to the merger discussed
under Risk Factors, among others, could cause actual results to differ
materially from those described in the forward-looking statements. These
factors include: relative value of AOL Time Warner stock and America Online's
and Time Warner's stocks, the market's difficulty in valuing our new business
model, the failure to realize the anticipated benefits of the merger, conflicts
of interest of directors recommending the merger and adverse regulatory
conditions. Stockholders are cautioned not to place undue reliance on the
forward-looking statements, which speak only of the date of this joint proxy
statement-prospectus or the date of the document incorporated by reference in
this joint proxy statement-prospectus. None of America Online, Time Warner or
AOL Time Warner 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 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 Time Warner have filed with the Securities and Exchange
Commission.
 
   All subsequent forward-looking statements attributable to America Online,
Time Warner or AOL Time Warner or any person acting on their behalf are
expressly qualified in their entirety by the cautionary statements contained or
referred to in this section.

                        DELAWARE GENERAL CORPORATION LAW
 
Section 262. Appraisal Rights.
 
   (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to ((S)) 228
of this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and
the words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one (1) or more shares, or fractions
thereof, solely of stock of a corporation, which stock is deposited with the
depository.
 
   (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to ((S)) 251 (other than a merger effected pursuant to ((S))
251(g) of this title), ((S)) 252, ((S)) 254, ((S)) 257, ((S)) 258, ((S)) 263 or
((S)) 264 of this title:
 
     (1) Provided, however, that no appraisal rights under this section shall
  be available for the shares of any class or series of stock, which stock,
  or depository receipts in respect thereof, at the record date fixed to
  determine the stockholders entitled to receive notice of and to vote at the
  meeting of stockholders to act upon the agreement of merger or
  consolidation, were either (i) listed on a national securities exchange or
  designated as a national market system security on an interdealer quotation
  system by the National Association of Securities Dealers, Inc. or (ii) held
  of record by more than 2,000 holders; and further provided that no
  appraisal rights shall be available for any shares of stock of the
  constituent corporation surviving a merger if the merger did not require
  for its approval the vote of the stockholders of the surviving corporation
  as provided in subsection (f) of ((S)) 251 of this title.
 
     (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
  under this section shall be available for the shares of any class or series
  of stock of a constituent corporation if the holders thereof are required
  by the terms of an agreement of merger or consolidation pursuant to
  ((S))((S)) 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
  such stock anything except:
 
       a. Shares of stock of the corporation surviving or resulting from
    such merger or consolidation, or depository receipts in respect
    thereof;
 
       b. Shares of stock of any other corporation, or depository receipts
    in respect thereof, which shares of stock (or depository receipts in
    respect thereof) or depository receipts at the effective date of the
    merger or consolidation will be either listed on a national securities
    exchange or designated as a national market system security on an
    interdealer quotation system by the National Association of Securities
    Dealers, Inc. or held of record by more than 2,000 holders;
 
       c. Cash in lieu of fractional shares or fractional depository
    receipts described in the foregoing subparagraphs a. and b. of this
    paragraph; or
 
       d. Any combination of the shares of stock, depository receipts and
    cash in lieu of fractional shares or fractional depository receipts
    described in the foregoing subparagraphs a, b and c of this paragraph.
 
     (3) In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under ((S)) 253 of this title is not owned by
  the parent corporation immediately prior to the merger, appraisal rights
  shall be available for the shares of the subsidiary Delaware corporation.
 
                                      I-1

<PAGE>
 
   (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.
 
   (d) Appraisal rights shall be perfected as follows:
 
     (1) If a proposed merger or consolidation for which appraisal rights are
  provided under this section is to be submitted for approval at a meeting of
  stockholders, the corporation, not less than 20 days prior to the meeting,
  shall notify each of its stockholders who was such on the record date for
  such meeting with respect to shares for which appraisal rights are
  available pursuant to subsections (b) or (c) hereof that appraisal rights
  are available for any or all of the shares of the constituent corporations,
  and shall include in such notice a copy of this section. Each stockholder
  electing to demand the appraisal of such stockholder's shares shall deliver
  to the corporation, before the taking of the vote on the merger or
  consolidation, a written demand for appraisal of such stockholder's shares.
  Such demand will be sufficient if it reasonably informs the corporation of
  the identity of the stockholder and that the stockholder intends thereby to
  demand the appraisal of such stockholder's shares. A proxy or vote against
  the merger or consolidation shall not constitute such a demand. A
  stockholder electing to take such action must do so by a separate written
  demand as herein provided. Within 10 days after the effective date of such
  merger or consolidation, the surviving or resulting corporation shall
  notify each stockholder of each constituent corporation who has complied
  with this subsection and has not voted in favor of or consented to the
  merger or consolidation of the date that the merger or consolidation has
  become effective; or
 
     (2) If the merger or consolidation was approved pursuant to ((S)) 228 or
  ((S)) 253 of this title, each constituent corporation, either before the
  effective date of the merger or consolidation or within ten 10 days
  thereafter, shall notify each of the holders of any class or series of
  stock of such constituent corporation who are entitled to appraisal rights
  of the approval of the merger or consolidation and that appraisal rights
  are available for any or all shares of such class or series of stock of
  such constituent corporation, and shall include in such notice a copy of
  this section; provided that, if the notice is given on or after the
  effective date of the merger or consolidation, such notice shall be given
  by the surviving or resulting corporation to all such holders of any class
  or series of stock of a constituent corporation that are entitled to
  appraisal rights. Such notice may, and, if given on or after the effective
  date of the merger or consolidation, shall, also notify such stockholders
  of the effective date of the merger or consolidation. Any stockholder
  entitled to appraisal rights may, within 20 days after the date of mailing
  of such notice, demand in writing from the surviving or resulting
  corporation the appraisal of such holder's shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of such holder's shares. If such notice did not notify
  stockholders of the effective date of the merger or consolidation, either
  (i) each such constituent corporation shall send a second notice before the
  effective date of the merger or consolidation notifying each of the holders
  of any class or series of stock of such constituent corporation that are
  entitled to appraisal rights of the effective date of the merger or
  consolidation or (ii) the surviving or resulting corporation shall send
  such a second notice to all such holders on or within 10 days after such
  effective date; provided, however, that if such second notice is sent more
  than 20 days following the sending of the first notice, such second notice
  need only be sent to each stockholder who is entitled to appraisal rights
  and who has demanded appraisal of such holder's shares in accordance with
  this subsection. An affidavit of the secretary or assistant secretary or of
  the transfer agent of the corporation that is required to give either
  notice that such notice has been given shall, in the absence of fraud, be
  prima facie evidence of the facts stated therein. For purposes of
  determining the stockholders entitled to receive either notice, each
  constituent corporation may fix, in advance, a record date that shall be
  not more than 10 days prior to the date the notice is given, provided, that
  if the notice is given on or after the effective date of the merger or
  consolidation, the record date shall be such effective date. If no record
  date is fixed and the notice is given
 
                                      I-2

<PAGE>
 
  prior to the effective date, the record date shall be the close of business
  on the day next preceding the day on which the notice is given.
 
   (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10
days after such stockholder's written request for such a statement is received
by the surviving or resulting corporation or within 10 days after expiration of
the period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.
 
   (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.
 
   (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.
 
   (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court may,
in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on the
list filed by the surviving or resulting corporation pursuant to subsection (f)
of this section and who has submitted such stockholder's certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that such stockholder is not
entitled to appraisal rights under this section.
 
 
                                      I-3

<PAGE>
 
   (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
   (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
   (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation,
either within 60 days after the effective date of the merger or consolidation
as provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the
Court of Chancery shall be dismissed as to any stockholder without the approval
of the Court, and such approval may be conditioned upon such terms as the Court
deems just.
 
   (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
Item 20. Indemnification of Directors and Officers.
 
   Section 145(a) of the General Corporation Law of the State of Delaware
("Delaware Corporation Law") provides, in general, that a corporation shall
have the power to indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation), because the person is or
was a director or officer of the corporation. Such indemnity may be against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by the person in connection with
such action, suit or proceeding, if the person acted in good faith and in a
manner the person reasonably believed to be in or not opposed to the best
interests of the corporation and if, with respect to any criminal action or
proceeding, the person did not have reasonable cause to believe the person's
conduct was unlawful.
 
   Section 145(b) of the Delaware Corporation Law provides, in general, that a
corporation shall have the power to indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor because the person is or was a director or officer of the
corporation, against any expenses (including attorneys' fees) actually and
reasonably incurred by the person in connection with the defense or settlement
of such action or suit if the person acted in good faith and in a manner the
person reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnify for such expenses which the Court of Chancery or such other court
shall deem proper.
 
   Section 145(g) of the Delaware Corporation Law provides, in general, that a
corporation shall have the power to purchase and maintain insurance on behalf
of any person who is or was a director or officer of the corporation against
any liability asserted against the person in any such capacity, or arising out
of the person's status as such, whether or not the corporation would have the
power to indemnify the person against such liability under the provisions of
the law.
 
   Article VII of the Registrant's By-laws requires indemnification to the
fullest extent permitted under Delaware law or any person who is or was a
director or officer of the Registrant who is or was involved or threatened to
be made so involved in any proceeding, whether civil, criminal, administrative
or investigative, by reason of the fact that such person is or was serving as a
director, officer, employee or agent of the Registrant or was serving at the
request of the Registrant as a director, officer, employee or agent of any
other enterprise.
 
   The foregoing statements are subject to the detailed provisions of Section
145 of the Delaware Corporation Law and Article VII of the By-laws of the
Registrant.

Item 22. Undertakings
 
   The undersigned Registrant hereby undertakes:
 
     (1) that, for purposes of determining any liability under the Securities
  Act of 1933, each filing of the registrant's annual report pursuant to
  Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and,
  where applicable, each filing of an employee benefit plan's annual report
  pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
  incorporated by reference in this registration statement shall be deemed to
  be a new registration statement relating to the securities offered therein,
  and the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof;
 
     (2) that prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this registration
  statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), the issuer undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other items
  of the applicable form;
 
     (3) that every prospectus (i) that is filed pursuant to paragraph (2)
  immediately preceding, or (ii) that purports to meet the requirements of
  Section 10(a)(3) of the Act and is used in connection with an offering of
  securities subject to Rule 415, will be filed as a part of an amendment to
  the registration statement and will not be used until such amendment is
  effective, and that, for purposes of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof;
 
     (4) to respond to requests for information that is incorporated by
  reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
  Form, within one business day of receipt of any such request, and to send
  the incorporated documents by first class mail or other equally prompt
  means, including information contained in documents filed after the
  effective date of this registration statement through the date of
  responding to such request; and
 
     (5) to supply by means of a post-effective amendment all information
  concerning a transaction, and the company being acquired involved therein,
  that was not the subject of and included in this registration statement
  when it became effective.
 
   Insofar as indemnification for liabilities under the Securities Act of 1933
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 20 above, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is therefore unenforceable. If a claim of
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in a successful defense of any action, suit or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
