Dear EarthLink Network, Inc. and MindSpring Enterprises, Inc. Stockholders:

    The boards of directors of EarthLink Network, Inc. and MindSpring
Enterprises, Inc. have agreed on the reorganization of EarthLink and MindSpring
into a new company. This proposed transaction is structured as a stock-for-stock
"merger of equals" that will create the nation's second largest Internet service
provider with approximately 2.85 million members, based on September 30, 1999
data. We believe that the combined strengths of the two companies will enable us
to compete more effectively on a national basis as the Internet access business
continues to evolve. We are convinced that this transaction will enable the
combined company to achieve its strategic goals and enhance its market position
more quickly than either EarthLink or MindSpring could have achieved on its own.

    In the transaction, EarthLink and MindSpring will combine into a new
corporation to be headquartered in Atlanta and initially named "WWW
Holdings, Inc." Each share of EarthLink common stock that you hold will be
converted automatically into the right to receive 1.615 shares of common stock
of WWW Holdings. Each share of MindSpring common stock that you hold will be
converted automatically into one share of common stock of WWW Holdings. Upon
completion of the reorganization, WWW Holdings will change its name to
"EarthLink, Inc." EarthLink's NASDAQ trading symbol is "ELNK" and MindSpring's
NASDAQ trading symbol is "MSPG." The NASDAQ trading symbol for the new company
will be "ELNK."


    We cannot complete the reorganization unless the stockholders of both of our
companies adopt the reorganization agreement. Each of us will hold a meeting of
our stockholders to vote on this reorganization proposal. YOUR VOTE IS VERY
IMPORTANT. Whether or not you plan to attend your stockholders' meeting, please
take the time to vote by completing and mailing the enclosed proxy card to us or
by voting by telephone or through the Internet as instructed on the proxy card.
If you sign, date and mail your proxy card without indicating how you want to
vote, your proxy will be counted as a vote in favor of the reorganization
agreement. Not returning your card or voting by telephone or through the
Internet, or not instructing your broker how to vote any shares held for you in
"street name," will have the same effect as a vote against the reorganization.


    The dates, times and places of the meetings are as follows:

                 QUESTIONS AND ANSWERS ABOUT THE REORGANIZATION

Q: WHY ARE EARTHLINK AND MINDSPRING PROPOSING THE REORGANIZATION?

A: We are proposing the reorganization because we believe the combined strengths
    of the two companies will enable us to compete more effectively on a
    national basis. The combination of EarthLink and MindSpring will create the
    second largest Internet service provider in the United States.

Q.  WHAT WILL HAPPEN TO EARTHLINK AND MINDSPRING AS A RESULT OF THE
    REORGANIZATION?

A: If the reorganization is completed, both EarthLink and MindSpring will merge
    into WWW Holdings, Inc., which is a company formed to accomplish the
    consolidation of the two companies. WWW HOLDINGS WILL CHANGE ITS NAME TO
    "EARTHLINK, INC." AND ITS COMMON STOCK WILL TRADE ON THE NASDAQ NATIONAL
    MARKET AS "ELNK."

Q: WHAT WILL I RECEIVE IN THE REORGANIZATION?

A: EARTHLINK COMMON STOCKHOLDERS: Under the terms of the reorganization
    agreement, you will receive 1.615 shares of WWW Holdings common stock for
    each share of EarthLink common stock you own.

B:  MINDSPRING COMMON STOCKHOLDERS: The reorganization agreement provides that
    you will receive one share of WWW Holdings common stock for each share of
    MindSpring common stock you own.

Q: HOW WILL THE REORGANIZATION AFFECT MY STOCK DIVIDENDS?

A: Neither EarthLink nor MindSpring has historically paid dividends to its
    stockholders. We do not anticipate that WWW Holdings will pay dividends to
    its stockholders in the foreseeable future.

Q: WHEN DO EARTHLINK, MINDSPRING AND WWW HOLDINGS EXPECT THE REORGANIZATION TO
    BE COMPLETED?

A: EarthLink, MindSpring and WWW Holdings are working to complete the
    reorganization as quickly as possible. We hope to complete the
    reorganization during the first quarter of 2000.

Q: WHAT DO I NEED TO DO NOW?

A: You should carefully read and consider the information contained in this
    joint proxy statement/prospectus. You should then complete and sign your
    proxy and return it in the enclosed return envelope as soon as possible so
    that your shares will be represented at your company's special meeting. If
    you sign, date and mail your proxy card without identifying how you want to
    vote, your proxy will be voted "FOR" the reorganization agreement. You may
    also vote your shares by telephone or through the Internet by following the
    instructions provided on the enclosed proxy form. If you do not vote in
    person, by telephone, by Internet or by returning your completed proxy card,
    it will have the same effect as a vote "AGAINST" the reorganization
    agreement.

Q.  ARE EARTHLINK OR MINDSPRING STOCKHOLDERS ENTITLED TO DISSENTERS' RIGHTS?

A: No. Under Delaware law, which governs both companies, neither the EarthLink
    stockholders nor the MindSpring stockholders are entitled to dissenters'
    rights of appraisal or other rights to demand fair value for their shares in
    cash by reason of the reorganization.

Q: WHO MUST APPROVE THE REORGANIZATION?


A: In addition to the approvals of the boards of directors of EarthLink,
    MindSpring and WWW Holdings, which have already been obtained, the
    stockholders of EarthLink and MindSpring must approve the reorganization
    agreement.


Q.  CAN I CHANGE MY VOTE AFTER I MAIL MY SIGNED PROXY OR VOTE BY TELEPHONE OR
    THROUGH THE INTERNET?


A: Yes. 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


                                       1
<PAGE>

    can send a written notice stating that you would like to revoke your proxy.
    Second, you can complete and submit a new proxy. If you choose either of
    these two methods, you must submit your notice of revocation or your new
    proxy for EarthLink shares at the address on page 29 and for MindSpring
    shares at the address on page 31. Third, you can attend the special meeting
    of your company's stockholders and vote in person. If you vote by telephone
    or through the Internet, you can also change your vote by any of these three
    methods or you can revote by following the instructions on the enclosed
    proxy form.


Q: MY SHARES ARE HELD IN "STREET NAME." WILL MY BROKER VOTE MY SHARES ON THE
    REORGANIZATION?

A: A broker will vote your shares with respect to the reorganization agreement
    only if you provide him or her with instructions on how to vote. You should
    follow the directions provided by your broker regarding how to instruct
    brokers to vote the shares.

Q: SHOULD I SEND IN MY CERTIFICATES NOW?

A: NO, YOU SHOULD NOT SEND IN YOUR STOCK CERTIFICATES WITH YOUR PROXY. You will
    receive instructions for exchanging your stock certificates if the
    reorganization is consummated.

Q: WHO CAN HELP ANSWER MY QUESTIONS?

A: If you have any questions about the reorganization or if you need additional
    copies of this joint proxy statement/ prospectus or the enclosed proxy, you
    should contact EarthLink's and MindSpring's proxy solicitor:

through simple, rapid and reliable access to the Internet, high quality service
and member education and support.

    1430 West Peachtree Street, NW,

    Atlanta, Georgia 30309
    Telephone: (404) 815-0770

    WWW HOLDINGS, INC.
    3100 New York Drive
    Pasadena, California 91107
    Telephone: (626) 296-2400

    WWW Holdings, Inc. is a newly formed corporation that has not, to date,
conducted any activities other than those incident to its formation, the
execution of the reorganization agreement and the preparation of this joint
proxy statement/prospectus. IN THE REORGANIZATION, EARTHLINK AND MINDSPRING WILL
MERGE INTO WWW HOLDINGS AND WWW HOLDINGS WILL CHANGE ITS NAME TO
"EARTHLINK, INC." The business of WWW Holdings will be the combined businesses
currently conducted by EarthLink and MindSpring. We anticipate that immediately
after the reorganization is completed, based on December 20, 1999 data and after
giving effect to Apple's investment in EarthLink, (1) the former common and
preferred stockholders of EarthLink will own approximately 82.5 million shares,
or 53.3%, of the WWW Holdings common stock on a fully diluted basis, which
assumes conversion of the preferred stock into common stock, and (2) the former
common stockholders of MindSpring will own approximately 72.2 million shares, or
46.7%, of the WWW Holdings common stock on a fully diluted basis.


THE REORGANIZATION (PAGE 32)


    The reorganization agreement is attached as ANNEX A to this joint proxy
statement/prospectus and is incorporated by reference into this document. We
encourage you to read the entire reorganization agreement because it is the
legal document that governs the reorganization.

    The reorganization agreement provides for the combination of EarthLink and
MindSpring in a stock-for-stock merger of equals. If the reorganization is
adopted by our stockholders,

                                       3
<PAGE>
we will combine our businesses through two separate mergers into WWW Holdings.


    Some stockholders of EarthLink, including members of management and the
board of directors, who collectively own approximately 29.3% of EarthLink's
outstanding common stock, and some stockholders of MindSpring, including members
of management and the board of directors, who collectively own approximately
24.5% of MindSpring's outstanding common stock, have signed agreements to vote
their shares in favor of the reorganization. See "EarthLink and MindSpring
Stockholder Agreements" on page 34 for a more detailed description of the
stockholder agreements.



    In addition, EarthLink and MindSpring have granted each other options under
which, in certain circumstances, EarthLink can buy up to 19.9% of the common
stock of MindSpring or MindSpring can buy up to 19.9% of the common stock of
EarthLink. See "EarthLink and MindSpring Stock Option Agreements" beginning on
page 33 for a more detailed discussion of the option agreements.



WHAT YOU WILL RECEIVE IN THE REORGANIZATION (PAGE 34)


    In the merger of EarthLink into WWW Holdings, each share of EarthLink common
stock will be converted into 1.615 shares of WWW Holdings common stock. In the
merger of MindSpring into WWW Holdings, each share of MindSpring common stock
will be converted into one share of WWW Holdings common stock.

    Former EarthLink common stockholders will receive cash in payment for any
fraction of a share of WWW Holdings common stock that they would be entitled to
receive in the reorganization. The value of this fraction of a share will be
determined based on the mean of the high and low sales prices of WWW Holdings
common stock on its first full day of trading on The Nasdaq National Market.

    Each share of EarthLink series A convertible preferred stock will be
converted into 1.615 shares of WWW Holdings series A convertible preferred
stock, each share of EarthLink series B convertible preferred stock will be
converted into 1.615 shares of WWW Holdings series B convertible preferred stock
and each share of EarthLink series C convertible preferred stock will be
converted into 1.615 shares of WWW Holdings series C convertible preferred
stock.


    The terms of the WWW Holdings series A convertible preferred stock, the WWW
Holdings series B convertible preferred stock and the WWW Holdings series C
convertible preferred stock will be the same as the terms of the EarthLink
series A convertible preferred stock, the EarthLink series B convertible
preferred stock and the EarthLink series C convertible preferred stock. The WWW
Holdings series A convertible preferred stock and the WWW Holdings series B
convertible preferred stock will be convertible into WWW Holdings common stock
at the option of the holder and the WWW Holdings series C convertible preferred
stock will be convertible into WWW Holdings common stock at the option of the
holder beginning on January 4, 2001. Immediately after the mergers, based on
December 20, 1999 data, assuming acceleration of the series A and B convertible
preferred stock conversion rights and assuming that Apple's $200 million
investment in EarthLink had occurred on December 20, 1999, the WWW Holdings
series A and B convertible preferred stock will be convertible into
approximately 14.2 million shares, or 9.2%, of WWW Holdings common stock on a
fully diluted basis.


OPTIONS, WARRANTS AND OTHER RIGHTS

    Each outstanding option, warrant and other right to purchase shares of
EarthLink common stock will be converted into an option, warrant or other right,
as the case may be, to purchase a number of shares of WWW Holdings common stock
equal to the number of shares of EarthLink common stock that were subject to the
option, warrant or other right, multiplied by 1.615. The exercise price per
share for each option, warrant or other right will be divided by 1.615. All
other terms will remain unchanged.

    Each outstanding option, warrant and other right to purchase shares of
MindSpring common

                                       4
<PAGE>
stock will be converted into an option, warrant or other right, as the case may
be, to purchase the same number of shares of WWW Holdings common stock on the
same terms and conditions, including the same exercise price.


CONVERTIBLE NOTES OF MINDSPRING (PAGE 35)


    Completion of the reorganization will constitute a "change in control" of
MindSpring under the indentures governing the 5% convertible subordinated notes
due 2006 issued by MindSpring in April 1999. Consequently, after the
reorganization is completed, each holder of notes will have the option to
require WWW Holdings to repurchase that holder's notes at a repurchase price of
100% of the principal amount plus accrued interest to the date of repurchase.
The reorganization agreement provides that the repurchase price for the notes
will be paid in cash. Notes not repurchased will become notes of WWW Holdings
convertible into WWW Holdings common stock.


THE EARTHLINK SPECIAL MEETING (PAGE 28)


    The special meeting of EarthLink stockholders will be held in the Town Hall
Conference Room, at 2947 Bradley Street, Pasadena, California, on February 4,
2000, at 8:00 a.m., local time.

    At the special meeting, EarthLink stockholders will be asked to vote to
adopt the reorganization agreement. Adoption of the reorganization agreement
requires the favorable vote of a majority of the outstanding shares of EarthLink
common stock. The vote of the holders of EarthLink's preferred stock is not
required to adopt the reorganization agreement.

    You can vote at the special meeting of EarthLink stockholders if you owned
EarthLink common stock at the close of business on December 20, 1999. As of that
date, directors and executive officers of EarthLink owned approximately 31% of
the outstanding shares of EarthLink common stock.

    If you do not vote your shares of EarthLink common stock, the effect will be
the same as a vote against the reorganization agreement.

THE MINDSPRING SPECIAL MEETING (PAGE 30)



    The special meeting of MindSpring stockholders will be held at the Georgia
Center for Advanced Telecommunications Technology (GCATT), Auditorium,
250 14th Street, NW, Atlanta, Georgia, on February 4, 2000, at 11:00 a.m., local
time.


    At the special meeting, MindSpring stockholders will be asked to vote to
adopt the reorganization agreement. Adoption of the reorganization agreement
requires the favorable vote of a majority of the outstanding shares of
MindSpring common stock.

    You can vote at the special meeting of MindSpring stockholders if you owned
MindSpring common stock at the close of business on December 20, 1999. As of
that date directors and executive officers of MindSpring owned approximately
7.8% of the outstanding shares of MindSpring common stock.

    If you do not vote your shares, the effect will be the same as a vote
against the reorganization agreement.


EARTHLINK'S REASONS FOR THE REORGANIZATION (PAGE 38)


    The EarthLink board of directors believes that the reorganization is
advisable and in the best interests of EarthLink and its stockholders, and that
it offers strategic and financial benefits to EarthLink. In reaching its
decision, the EarthLink board of directors considered the following factors,
among others:

- - the EarthLink board's thorough evaluation of a variety of potential strategic
  alternatives and its analysis of the viability of, and risks associated with,
  each alternative;

- - the potential increased value of the EarthLink brand after the reorganization;

- - the combination of the companies' member bases to form the second largest
  Internet service provider in the United States;

- - the combined management skills of the two companies' management teams;

- - the ability to take advantage of the greater combined resources and efforts of
  the two

                                       5
<PAGE>
  companies under one brand to accelerate member growth;

- - the competitive environment in the Internet industry;

- - the possible financial benefit of the reorganization to EarthLink's
  relationships with its existing and potential members; and

- - the opinion of Credit Suisse First Boston Corporation, EarthLink's financial
  advisor, that the EarthLink common stock exchange ratio was fair from a
  financial point of view to the EarthLink common stockholders, other than
  MindSpring and its affiliates, the EarthLink series A preferred stock exchange
  ratio was fair from a financial point of view to the holders of the EarthLink
  series A preferred stock, and the EarthLink series B preferred stock exchange
  ratio was fair from a financial point of view to the holders of the EarthLink
  series B preferred stock.

    The EarthLink board of directors also considered potentially negative
factors in arriving at its decision, including among others:

- - the potential disruption of EarthLink's business that might result from the
  announcement of the reorganization;

- - the risk that anticipated benefits of the reorganization for EarthLink
  stockholders may not be realized; and

- - the risk that the reorganization would not be consummated and that, under some
  circumstances, EarthLink could be required to pay a termination fee to
  MindSpring.

    The EarthLink board did not believe that the negative factors were
sufficient, individually or in the aggregate, to outweigh the potential
advantages of the reorganization.


    You should recognize, however, that EarthLink's stockholders may not achieve
the benefits of the reorganization mentioned above because of the risks and
uncertainties discussed in the section "Risk Factors Relating to the
Reorganization" beginning on page 17 and the section "A Caution About
Forward-Looking Statements" beginning on page 15.



MINDSPRING'S REASONS FOR THE REORGANIZATION (PAGE 47)


    The MindSpring board of directors believes that the reorganization is
advisable and in the best interests of MindSpring and its stockholders, and that
it offers strategic and financial benefits to MindSpring. In reaching its
decision, the MindSpring board of directors considered the following factors,
among others:

- - the opportunity of the two companies to create the second largest provider of
  Internet access in the U.S. after America Online, Inc., and establish the
  combined company as a national brand alternative to America Online;

- - the strategic alternatives available to MindSpring, including potential
  business combinations with other entities, and the strong strategic fit
  between MindSpring and EarthLink;

- - the ability of the combined company to share resources and capitalize on
  synergies to better attract and retain members;

- - the increased opportunities that could be available to the larger, combined
  company, including potentially greater leverage with vendors, network
  providers and content providers;

- - the opportunity to become a leading Internet service provider portal site and
  the opportunity to develop alternative revenue streams;

- - the significant opportunities for cost savings, revenue growth, technological
  development and other benefits resulting from the reorganization; and

- - the opinion of Donaldson, Lufkin & Jenrette Securities Corporation,
  MindSpring's financial advisor, that, as of the date of the opinion, the ratio
  for the exchange of shares of MindSpring common stock for shares of WWW
  Holdings common stock in the reorganization was fair, from a financial point
  of view, to the stockholders of MindSpring.


    You should recognize, however, that MindSpring's stockholders may not
achieve the benefits of the reorganization mentioned above


                                       6
<PAGE>

because of the risks and uncertainties discussed in the section "Risk Factors
Relating to the Reorganization" beginning on page 17 and the section "A Caution
About Forward-Looking Statements" beginning on page 15. In addition, as a result
of the reorganization:


- - we anticipate that initially the loss per share of WWW Holdings will be
  greater than the loss per share of MindSpring had the reorganization not
  occurred;

- - the holders of MindSpring's 5% convertible subordinated notes will have the
  option to require WWW Holdings to repurchase the notes at a repurchase price
  equal to one hundred percent (100%) of the principal amount plus accrued
  interest; and

- - unless renegotiated, MindSpring will be in default under its credit agreement
  with the group of financial institutions led by First Union National Bank and
  these lenders will have the right to terminate MindSpring's credit facility.

    In the opinion of the MindSpring board of directors, these considerations
are not sufficient, individually or in the aggregate, to outweigh the potential
advantages of the reorganization.


OUR RECOMMENDATIONS TO STOCKHOLDERS



EARTHLINK (PAGE 40)


    All of the members of the board of directors of EarthLink recommend that its
stockholders vote "FOR" the adoption of the reorganization agreement.

MINDSPRING (PAGE 49)


    All of the members of the board of directors of MindSpring recommend that
its stockholders vote "FOR" the adoption of the reorganization agreement.


COMPARATIVE PER SHARE MARKET PRICE AND DIVIDEND INFORMATION (PAGE 10)



    Shares of EarthLink and MindSpring common stock are listed on The Nasdaq
National Market. On September 22, 1999, the last trading day prior to the public
announcement of the proposed reorganization, EarthLink common stock closed at
$43 1/2 per share and MindSpring common stock closed at $32 7/8 per share. On
January 6, 2000, the last day for which such information was available before
the date of this joint proxy statement/prospectus, EarthLink common stock closed
at $43.25 per share and MindSpring common stock closed at $26.88 per share.


    Neither EarthLink nor MindSpring has historically paid dividends. We do not
anticipate that WWW Holdings will pay dividends to its stockholders in the
foreseeable future.


OPINION OF EARTHLINK FINANCIAL ADVISOR (PAGE 41)


    In deciding to approve the reorganization agreement, the EarthLink board of
directors considered a number of factors, including the opinion of its financial
advisor, Credit Suisse First Boston Corporation. On September 22, 1999, Credit
Suisse First Boston delivered to the EarthLink board of directors its opinion
that, as of that date, the EarthLink common stock exchange ratio was fair from a
financial point of view to the EarthLink common stockholders, other than
MindSpring and its affiliates, the EarthLink series A preferred stock exchange
ratio was fair from a financial point of view to the holders of the EarthLink
series A preferred stock, and the EarthLink series B preferred stock exchange
ratio was fair from a financial point of view to the holders of the EarthLink
series B preferred stock.

OPINION OF MINDSPRING FINANCIAL ADVISOR (PAGE 49)


    In connection with the reorganization, the MindSpring board received a
written opinion from Donaldson, Lufkin & Jenrette Securities Corporation as to
the fairness, from a financial point of view, to the holders of MindSpring
common stock, of the ratio for the exchange of shares of MindSpring common stock
for shares of WWW Holdings common stock in the reorganization. The opinion was
delivered to the MindSpring board on September 22, 1999.


    THE FULL TEXT OF DONALDSON, LUFKIN & JENRETTE'S OPINION, DATED
SEPTEMBER 22, 1999, IS ATTACHED TO THIS JOINT PROXY STATEMENT/PROSPECTUS AS

SEPTEMBER 22, 1999, IS DIRECTED TO THE MINDSPRING BOARD AND DOES NOT CONSTITUTE
A RECOMMENDATION TO ANY STOCKHOLDER WITH RESPECT TO ANY MATTER RELATING TO THE
PROPOSED REORGANIZATION.



REGULATORY APPROVALS (PAGE 60)



    In order to complete the reorganization, EarthLink and MindSpring were
required to make filings with the Department of Justice and the Federal Trade
Commission and wait for the expiration or early termination of the required
waiting period. EarthLink and MindSpring received notice on November 3, 1999
that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976 had been terminated.



CONDITIONS TO THE REORGANIZATION (PAGE 75)


    The reorganization will not be completed unless customary conditions are
satisfied or waived by EarthLink, MindSpring and WWW Holdings. Examples of the
conditions include stockholder approval, regulatory approval and the absence of
governmental action to block the reorganization. None of the preceding
conditions may be waived. If either EarthLink or MindSpring waives a material
condition to the consummation of the reorganization, it intends to resolicit
stockholder approval of the reorganization. Material conditions to the
consummation of the reorganization would include the receipt of a letter from
each of MindSpring's and EarthLink's independent public accountants that the
accountants concur with their client's management's conclusions that no
conditions exist with respect to their client that would preclude WWW Holdings
from accounting for the mergers of EarthLink and MindSpring into WWW Holdings as
a pooling of interests and the receipt of legal opinions that the mergers of
EarthLink and MindSpring into WWW Holdings will qualify as reorganizations
within the meaning of the federal income tax laws.


TERMINATION OF THE REORGANIZATION AGREEMENT (PAGE 75)



    The reorganization agreement may be terminated by either EarthLink or
MindSpring in a number of circumstances, in which case the reorganization will
not be consummated. Breaches of the reorganization agreement, withdrawal of a
board of directors' recommendation that stockholders adopt the reorganization
agreement and the failure of a company's stockholders to adopt the
reorganization agreement are some of the factors that could permit EarthLink or
MindSpring to terminate the reorganization agreement. See "Termination" on
page 75 for a more detailed description of the termination provisions of the
reorganization agreement.



TERMINATION FEE (PAGE 76)



    If the reorganization agreement is terminated, under some circumstances
EarthLink may have to pay MindSpring, or MindSpring may have to pay EarthLink, a
termination fee of $70,000,000. See "Payment of Termination Fee by EarthLink"
and "Payment of Termination Fee by MindSpring" on pages 76 and 77 for more
information about when a termination fee may become payable.

<PAGE>

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (PAGE 55)


    One of the conditions to the consummation of the reorganization is that the
exchange of your EarthLink common stock or MindSpring common stock for WWW
Holdings common stock qualify as a tax-free exchange of stock for United States
federal income tax purposes. Even with the tax-free treatment, however, you will
be taxed on any cash you receive for any fraction of a share.


    To review the tax consequences of the reorganization in greater detail,
please read the tax discussion beginning on page 55.



ACCOUNTING TREATMENT (PAGE 55)


    The companies have structured the reorganization to be accounted for as a
pooling of interests for financial reporting and accounting purposes in
accordance with generally accepted accounting principles.


INTERESTS OF EARTHLINK OFFICERS AND DIRECTORS IN THE REORGANIZATION (PAGE 58)


    In considering the EarthLink board's recommendation that you vote for the
reorganization agreement, you should be aware that some of the EarthLink
officers and directors identified in this joint proxy statement/ prospectus have
interests in the reorganization that are different from, or in addition to,
their rights as EarthLink stockholders.


INTERESTS OF MINDSPRING OFFICERS AND DIRECTORS IN THE REORGANIZATION (PAGE 59)


    In considering the MindSpring board's recommendation that you vote for the
reorganization agreement, you should be aware that some of the MindSpring
officers and directors identified in this joint proxy statement/ prospectus have

their rights as MindSpring stockholders.


COMPARISON OF STOCKHOLDER RIGHTS (PAGE 163)



    When the reorganization is completed, EarthLink and MindSpring stockholders
will become holders of WWW Holdings common stock. Their rights will continue to
be governed by Delaware law, but will also be governed by WWW Holdings'
certificate of incorporation and bylaws (instead of EarthLink's or MindSpring's
certificate of incorporation and bylaws). The material differences between the
rights of WWW Holdings stockholders and those of EarthLink or MindSpring
stockholders are summarized beginning on page 163.

</TABLE>

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

(1) Basic earnings (loss) per common share was computed by dividing net income
    (loss) attributable to common stockholders by the weighted-average number of
    shares of common stock outstanding for the period then ended. Diluted
    earnings (loss) per common share reflects the potential dilution that could
    occur if options, similar securities or other contracts to issue common
    stock were exercised or converted into common stock. However, WWW Holdings
    has not included potential common stock in the calculation of earnings
    (loss) per common share as such inclusion would have an anti-dilutive
    effect.

(2) Basic earnings (loss) per common share was computed by dividing net income
    (loss) by the weighted-average number of shares of common stock outstanding
    for the period then ended. The effect of the MindSpring's stock options,
    using the treasury stock method, was included in the computation of diluted
    earnings (loss) per common share for the year ended December 31, 1998 and
    the nine months ended September 30, 1998. For the nine months ended
    September 30, 1999 and each of the two years ended December 31, 1997 and
    1996, the effect of the options is excluded, as it is anti-dilutive.

(3) The historical book value per share is computed by dividing common
    stockholders' equity by the number of shares of common stock outstanding at
    September 30, 1999. The pro forma combined book value per share is computed
    by dividing pro forma common stockholders' equity by the pro forma number of
    shares of WWW Holdings common stock outstanding as of September 30, 1999, as
    if the reorganization had occurred as of that date.

(4) The book value per equivalent EarthLink share is calculated by multiplying
    the book value per WWW Holdings share amount by the exchange ratio of 1.615.
    The book value per equivalent MindSpring share remains unchanged as the
    exchange ratio to WWW Holdings is 1-to-1.

    interest. For the Inception Period, the years ended December 31, 1995, 1996,
    and 1997 and the nine months ended September  30, 1999, earnings would have
    been insufficient to cover fixed charges by $75, $1,959, $7,612, $4,083, and
    $27,859, respectively.

         WWW HOLDINGS SELECTED PRO FORMA COMBINED FINANCIAL INFORMATION

    The selected unaudited pro forma combined financial data present the effect
of the proposed consolidation of EarthLink and MindSpring on a pooling of
interests basis, and the January 5, 2000 investment by Apple Computer of
$200 million in EarthLink. The EarthLink and MindSpring unaudited pro forma
combined financial data are based on the historical consolidated financial
statements and the related notes included elsewhere in this document. The
unaudited pro forma combined balance sheet data assume that the consolidation of
EarthLink and MindSpring into WWW Holdings and the investment by Apple Computer
took place on September 30, 1999. The unaudited pro forma combined statements of
operations data assume that the consolidation of EarthLink and MindSpring took
place as of the beginning of the periods presented. In addition, the unaudited
pro forma combined statements of operations data reflect acquisitions completed
by EarthLink and MindSpring during 1999 and 1998 as described below as if the
acquisitions had been completed on January 1, 1998.

    On June 5, 1998, EarthLink acquired the Sprint Internet Passport business of
Sprint Corporation in a transaction accounted for as a purchase. The unaudited
pro forma combined statement of operations data for the year ended December 31,
1998 and the nine months ended September 30, 1998 is based upon Sprint Internet
Passport's historical results of operations and combines the results of
operations as if the transaction had been completed on January 1, 1998.

    On October 15, 1998, MindSpring acquired from America Online, Inc. assets
used in connection with the consumer dial-up Internet access business of
Spry, Inc. On February 17, 1999, MindSpring acquired some of the tangible and
intangible assets and rights used in connection with the Internet services
business operated in the United States by NETCOM On-Line Communication
Services, Inc. The unaudited pro forma combined statements of operations data
reflect the Spry, Inc. acquisition as if it occurred on January 1, 1997, for the
year ended December 31, 1997, and January 1, 1998, for the year ended
December 31, 1998 and the nine months ended September 30, 1998. In addition, the
unaudited pro forma combined statement of operations data for the nine months
ended September 30, 1999 reflects the acquisition of NETCOM as if it had been
completed on January 1, 1998.


    The unaudited pro forma combined financial data are presented for
illustrative purposes only and are not necessarily indicative of the combined
financial position or results of operations of future periods or the results
that actually would have been realized had the entities been a single entity
during these periods. The unaudited pro forma combined financial data as of
September 30, 1999 and for each of the three years in the period ended
December 31, 1998, and for the nine months ended September 30, 1999 and 1998,
are derived from the unaudited pro forma condensed combined financial statements
included elsewhere in this document and should be read in conjunction with those
statements and the related notes. See "WWW Holdings Pro Forma Financial
Information" on page 78.

                   A CAUTION ABOUT FORWARD-LOOKING STATEMENTS

    The matters discussed throughout this joint proxy statement/prospectus that
are not historical facts are forward-looking and, accordingly, involve
estimates, projections, goals, forecasts, assumptions and uncertainties that
could cause actual results or outcomes to differ materially from those expressed
in the forward-looking statements.

    These forward-looking statements may relate to, but are not limited to,
future capital expenditures, acquisitions, future revenues, earnings, margins,
costs, demand for Internet access, market trends in the Internet service
business, inflation and various economic and business trends. You can identify
forward-looking statements by the use of words such as "expect," "estimate,"
"project," "budget," "forecast," "anticipate," "plan" and similar expressions.
Forward-looking statements include all statements regarding expected financial
position, results of operations, cash flows, dividends, financing plans,
business strategies, operating efficiencies or synergies, budgets, capital and
other expenditures, competitive positions, growth opportunities for existing or
proposed products or services, plans and objectives of management, and markets
for stock of WWW Holdings, EarthLink and MindSpring.

    Examples of factors that you should consider with respect to any
forward-looking statements made throughout this joint proxy statement/prospectus
include, but are not limited to, the following:

    - general industry trends and the effects of vigorous competition in the
      Internet access and business services industry, including the entry of
      large computer hardware and software, media and telecommunications
      companies into the industry;

    - legislative and regulatory initiatives that could affect the provision of
      Internet services;

    - market demand for Internet services, changes in the economies of
      geographic areas served by the companies and catastrophic natural
      disasters;

    - the ability of EarthLink, MindSpring, WWW Holdings and their suppliers and
      customers to successfully address Year 2000 readiness issues;

    - unanticipated changes in operating expenses and capital expenditures;

    - customer business conditions, including demand for online access to their
      products or services;

    - financial or regulatory accounting principles or policies imposed by the
      Financial Accounting Standards Board, the Securities and Exchange
      Commission and similar agencies with regulatory oversight;

    - employee workforce factors, including loss or retirement of key
      executives;

    - the availability and terms of Internet service provider access to
      broadband facilities owned by other companies;

    - technological developments resulting in competitive disadvantages and
      creating the potential for impairment of existing assets;

    - unexpected costs or difficulties related to the integration of the
      businesses of EarthLink and MindSpring;

    - regulatory delays or conditions imposed by regulatory bodies in approving
      the reorganization;

    - general economic factors including inflation and capital market
      conditions; and

    - adverse changes in the securities markets.

    These factors are difficult to predict. They also involve uncertainties that
may materially affect actual results, and may be beyond the control of
EarthLink, MindSpring or WWW Holdings. New

                                       15
<PAGE>
factors may emerge from time to time and it is not possible for us to predict
new factors, nor can we assess the potential effect of any new factors on
EarthLink, MindSpring or WWW Holdings.

    These forward-looking statements are found at various places throughout this
joint proxy statement/prospectus. We caution you not to place undue reliance on
these forward-looking statements, which speak only as of the date they were
made. None of EarthLink, MindSpring or WWW Holdings undertakes any obligation to
publicly release any revisions to these forward-looking statements to reflect
events or circumstances after the date of this joint proxy statement/prospectus
or to reflect the occurrence of events that we do not currently anticipate.

                  RISK FACTORS RELATING TO THE REORGANIZATION

    IN ADDITION TO THE OTHER INFORMATION INCLUDED IN THIS JOINT PROXY
STATEMENT/PROSPECTUS, YOU SHOULD CAREFULLY READ AND CONSIDER THE FOLLOWING
FACTORS IN EVALUATING THE PROPOSALS TO BE VOTED ON AT YOUR COMPANY'S
STOCKHOLDERS MEETING.

    THE COSTS OF THE REORGANIZATION, THE COSTS OF INTEGRATING THE EARTHLINK AND
MINDSPRING BUSINESSES AND OTHER POTENTIAL ADJUSTMENTS ARE SUBSTANTIAL.

    We estimate that it will cost approximately $20.5 million to consummate the
reorganization. These costs will consist of transaction fees for investment
bankers, attorneys, accountants and other related costs incurred by EarthLink
and MindSpring. WWW Holdings expects to incur additional nonrecurring
restructuring charges, the amount of which has not been estimated. All of these
charges will be recorded in the period in which the reorganization is
consummated.

    There can be no assurance that WWW Holdings will not incur additional
charges in excess of these amounts to reflect costs associated with the
reorganization, including the costs of integrating the EarthLink and MindSpring
businesses.

    After the reorganization is completed, the holders of MindSpring's 5%
convertible subordinated notes will have the option to require WWW Holdings to
repurchase the notes at a repurchase price equal to one hundred percent (100%)
of the principal amount plus accrued interest. The reorganization agreement
provides that the repurchase price for the notes will be paid in cash. If all of
the holders of the notes exercise their repurchase rights, WWW Holdings will be
required to pay to the note holders up to $179,975,000 in cash plus accrued
interest. This would reduce WWW Holdings' cash on hand, which could have an
adverse effect on its business operations. On the other hand, if a substantial
portion of these notes remain outstanding, the amount of debt WWW Holdings would
have could adversely affect it by:

    - limiting its ability to obtain necessary financing;

    - potentially placing it at a disadvantage compared to its competitors who
      have lower levels of debt; and

    - making it more vulnerable in a business downturn.

    If MindSpring's secured credit facility is terminated or all or a portion of
MindSpring's 5% convertible subordinated notes are repurchased as a result of
the reorganization, WWW Holdings will recognize an expense of $1.8 million or up
to $5.8 million, respectively, related to deferred financing costs.

    AS A RESULT OF THE REORGANIZATION, WWW HOLDINGS WILL REVERSE MINDSPRING'S
PREVIOUSLY RECOGNIZED INCOME TAX BENEFITS.

    In 1998, MindSpring's management reviewed its net deferred tax asset,
consisting primarily of net operating loss carryforwards, and based on the net
income generated in 1998 as well as MindSpring's projections of future income,
determined that it was more likely than not that the deferred tax assets would
be realized. As a result of this determination, MindSpring reversed its
valuation allowance in 1998 and did not record an allowance for the nine months
ended September 30, 1999. In the course of the reorganization discussions,
management of EarthLink and MindSpring reviewed the combined net deferred tax
assets and concluded that, due to uncertainty related to the integration of the
two companies and the projected losses of WWW Holdings in the foreseeable
future, it is currently uncertain whether the net deferred tax assets will be
realized. Accordingly, upon consummation of the reorganization, WWW Holdings
expects to reverse the income tax benefits previously realized by MindSpring,
which aggregated to approximately $1.5 million for the year ended December 31,
1998 and $13.6 million for the nine months ended September 30, 1999, in its
combined financial statements for

                                       17
<PAGE>
those periods and to reestablish a valuation allowance on the MindSpring net
deferred tax asset, which was approximately $23.7 million at September 30, 1999.

    IF EARTHLINK AND MINDSPRING CANNOT BE SUCCESSFULLY INTEGRATED INTO A SINGLE
ENTITY, WE MAY NOT ACHIEVE THE ANTICIPATED BENEFITS OF THE REORGANIZATION.

    After the reorganization is completed, we will need to integrate two large
companies. The failure to successfully integrate our operations may adversely
affect WWW Holdings' business, operations, properties, assets, financial
condition, results of operations or business prospects. Integrating two
companies like EarthLink and MindSpring involves a number of risks, including:

    - the diversion of management's attention away from ongoing operations;

    - difficulties and expenses in combining the operations, technology and
      systems of the two companies;

    - difficulties and expenses in the assimilation and retention of employees,
      including the integration of teams that have not previously worked
      together;

    - difficulties in the creation and maintenance of uniform standards,
      controls, procedures and policies;

    - different geographic locations of the principal operations of EarthLink
      and MindSpring;

    - challenges in keeping and attracting members and business customers; and

    - potential adverse short-term effects on operating results, primarily as a
      result of increased costs resulting from the integration of the two
      businesses.

    INCREASED COMPETITION IN THE INTERNET SERVICE INDUSTRY MAY MAKE IT DIFFICULT
FOR WWW HOLDINGS TO ATTRACT AND RETAIN MEMBERS AND TO MAINTAIN CURRENT PRICING
LEVELS.

    We operate in the Internet services market, which is extremely competitive.
Our current and prospective competitors include many large companies that have
substantially greater market presence, financial, technical, marketing and other
resources than we have. We compete directly or indirectly with the following
categories of companies:

    - established online service providers, such as America Online, Inc., the
      Microsoft Network and Prodigy Communications Corporation;

    - local, regional and national Internet service providers, such as
      RMI.NET, Inc. and Internet America, Inc.;

    - national telecommunications companies, such as AT&T Corp. and GTE
      Corporation;

    - regional Bell operating companies, such as BellSouth Corporation and SBC
      Communications Inc.;

    - personal computer manufacturers with Internet service provider businesses
      such as Gateway, Inc. and Dell Computer Corporation;

    - "free access" Internet service providers, such as NetZero, Inc.; and

    - online cable services, such as Excite@Home Corporation and Roadrunner
      Computer Systems, Inc.

    We will also face competition from companies that provide broadband and
other high-speed connections to the Internet, including local and long-distance
telephone companies, cable television companies, electric utility companies, and
wireless communications companies. These companies may use broadband
technologies to include Internet access or Web hosting in their basic bundle of
services

                                       18
<PAGE>
or may offer Internet access or Web hosting services for a nominal additional
charge. Broadband technologies enable consumers to transmit and receive print,
video, voice and data in digital form at significantly faster access speeds than
existing dial-up modems.

    These companies may also prevent us from delivering Internet access through
their systems. If the owners of these high-speed, broadband facilities
increasingly use them to provide Internet access and we are unable to gain
access to these facilities on reasonable terms, our business, financial
condition and results of operations could be materially adversely affected.

    Neither EarthLink nor MindSpring currently competes internationally. If the
ability to provide Internet access internationally becomes a competitive
advantage in the Internet access industry, WWW Holdings may be at a competitive
disadvantage relative to our competitors.

    Our competition is likely to increase. We believe this will probably happen
as large diversified telecommunications and media companies acquire Internet
service providers, as Internet service providers consolidate into larger, more
competitive companies and as providers who offer free access to the Internet
grow in number and size. Diversified competitors may bundle other services and
products with Internet connectivity services, potentially placing us at a
significant competitive disadvantage. In addition, competitors may charge less
than we do for Internet services, or may charge nothing at all in some
circumstances, causing us to reduce, or preventing us from raising, our fees. As
a result, our business may suffer.

    WWW HOLDINGS' RESULTS OF OPERATIONS COULD BE AFFECTED BY FLUCTUATIONS IN THE
USE OF THE INTERNET FOR E-COMMERCE TRANSACTIONS.

    Use of the Internet for retail transactions is a relatively recent
development and the continued demand and growth of a market for services and
products via the Internet is uncertain. The Internet may ultimately prove not to
be a viable commercial marketplace for a number of reasons, including:

    - unwillingness of consumers to shift their purchasing from traditional
      retailers to online purchases;

    - lack of acceptable security for data and concern for privacy of personal
      information;

    - limitations on access and ease of use;

    - congestion leading to delayed or extended response times;

    - inadequate development of the Web infrastructure to keep pace with
      increased levels of use; and

    - increased or excessive government regulation.

    If use of the Internet for commercial transactions declines or does not
increase, and if other uses, such as e-mail and personal Web sites, do not
increase, this could have a material adverse effect on the business and results
of operations of WWW Holdings.

    ANY DISRUPTION IN THE INTERNET ACCESS PROVIDED BY WWW HOLDINGS COULD
ADVERSELY AFFECT WWW HOLDINGS' BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL
CONDITION.

    WWW Holdings' systems and infrastructure will be susceptible to natural and
man-made disasters such as earthquakes, fires, floods, power loss and sabotage.
WWW Holdings' systems also will be vulnerable to disruptions from computer
viruses and attempts by hackers to penetrate WWW Holdings' network security.

    WWW Holdings will be covered by insurance from loss of income from some of
the events listed above, but this insurance may not be adequate to cover all
instances of system failure. WWW Holdings also will have insurance from loss of
income due to earthquakes, but the amount of such insurance may

                                       19
<PAGE>
be insufficient, especially given the frequency and magnitude of earthquakes in
California, where a number of WWW Holdings' facilities will be located.

    Any of the events described above could cause interference, delays, service
interruptions or suspensions and adversely affect WWW Holdings' business and
results of operations.

    WWW Holdings must continue to expand and adapt its system infrastructure to
keep pace with the increase in the number of members who use the services it
expects to provide. Demands on infrastructure that exceed WWW Holdings' current
forecasts could result in technical difficulties with its servers. Continued or
repeated system failures could impair WWW Holdings' reputation and brand names
and reduce WWW Holdings' revenues.

    If, in the future, WWW Holdings cannot modify these systems to accommodate
increased traffic, WWW Holdings could suffer slower response times, problems
with customer service and delays in reporting accurate financial information.
Any of these factors could significantly and adversely affect the results of WWW
Holdings' operations.

    WWW HOLDINGS MUST CONTINUE TO ENHANCE ITS PRODUCTS AND SERVICES AND DEVELOP
NEW ONES TO BE SUCCESSFUL IN THE RAPIDLY EVOLVING MARKET FOR INTERNET SERVICES,
AND WE CANNOT BE CERTAIN THAT WWW HOLDINGS WILL BE ABLE TO DO SO
COST-EFFECTIVELY.

    Rapid technological change, changing customer needs, frequent new product
and service introductions and evolving industry standards characterize the
Internet market. These market characteristics could render WWW Holdings'
services, technology and systems obsolete. WWW Holdings must continually improve
the performance, features and reliability of its services to respond to evolving
market demands and competition. WWW Holdings' business, operating results and
financial condition would be materially adversely affected if it is unable to
respond in a cost-effective and timely manner to changing market conditions or
customer requirements.

    IF WWW HOLDINGS' THIRD PARTY NETWORK PROVIDERS ARE UNABLE OR UNWILLING TO
PROVIDE INTERNET ACCESS TO OUR MEMBERS ON COMMERCIALLY REASONABLE TERMS, WWW
HOLDINGS MAY SUFFER THE LOSS OF CUSTOMERS, HIGHER COSTS AND LOWER OVERALL
REVENUES.

    EarthLink provides dial-up access through company-owned points of presence
and through the networks of Worldcom/UUNet, PSINet, Level 3 and Sprint.
MindSpring provides dial-up access through company-owned points of presence and
through the networks of ICG Netahead, Worldcom/ UUNet, GTE/BBN and PSINet.
Approximately 94% of the members of WWW Holdings will live in a geographic area
served by two or more network providers. WWW Holdings will be able to serve its
members through the combination of network providers that it deems most
efficient. Only 6% of the members of WWW Holdings will live in a geographic area
served by only one network provider. The following providers are the sole
provider of network access for the percentage of our combined member base
indicated: UUNet, 2.8%; PSINet, 0.4%; Level 3, 0.4%; Sprint, 0.5%; EarthLink,
0.3%; MindSpring, 1.4%; and ICG Netahead, 0.3%. Our ability to provide Internet
access to our members will be limited if our third-party network providers are
unable or unwilling to provide access to our members, we are unable to secure
alternative arrangements upon termination of third-party network provider
agreements, or there is a loss of access to third-party providers for other
reasons. These events could also limit our ability to further expand nationally,
which could have a material adverse affect on our business. If we lose access to
third-party providers under current arrangements, we may not be able to make
alternative arrangements on terms acceptable to us, or at all. We do not
currently have any plans or commitments with respect to alternative third-party
provider arrangements in areas served by only one network provider. Moreover,
while the contracts with the third-party providers require them to provide
commercially reliable service to our members with a significant assurance of
accessibility to the Internet, the performance of third-party providers may not
meet our requirements, which could materially adversely affect our business,
financial condition and results of operations.

                                       20
<PAGE>
    WWW HOLDINGS MAY NOT BE ABLE TO MAINTAIN OR INCREASE ITS MEMBERSHIP LEVELS
IF IT DOES NOT HAVE UNINTERRUPTED AND REASONABLY PRICED ACCESS TO THE LOCAL AND
LONG-DISTANCE TELECOMMUNICATIONS LINES NECESSARY FOR IT TO PROVIDE INTERNET
ACCESS TO ITS MEMBERS.

    WWW Holdings will rely on local telephone companies and other companies to
provide data communications capacity through local telecommunications lines and
leased long-distance lines. We may experience disruptions or capacity
constraints in these telecommunications services. If disruptions or capacity
constraints occur, we may have no means of replacing these services on a timely
basis, or at all. In addition, local phone service is sometimes available only
from the local monopoly telephone company in each of the markets we serve. We
believe that the Federal Telecommunications Act of 1996 generally will lead to
increased competition in the provision of local telephone services, but we
cannot predict when or to what extent this will occur or the effect of increased
competition on pricing or supply.

    WWW HOLDINGS' REVENUES AND RESULTS OF OPERATIONS WILL BE DEPENDENT UPON WWW
HOLDINGS' PROPRIETARY TECHNOLOGY AND WWW HOLDINGS MAY NOT BE SUCCESSFUL IN
PROTECTING ITS PROPRIETARY RIGHTS OR AVOIDING CLAIMS THAT IT INFRINGES UPON THE
PROPRIETARY RIGHTS OF OTHERS.

    Our success depends in part upon the software and related documentation of
EarthLink and MindSpring. We principally rely upon copyright, trade secret and
contract laws to protect our proprietary technology. We cannot be certain that
we have taken adequate steps to prevent misappropriation of our technology or
that our competitors will not independently develop technologies that are
substantially equivalent or superior to our technology.

    We have permission and, in some cases, licenses from each manufacturer of
the software that we bundle in EarthLink's and MindSpring's front-end software
product for members. Although we do not believe that the software or the
trademarks we use or any of the other elements of our business infringe on the
proprietary rights of any third parties, third parties may assert claims against
us for infringement of their proprietary rights and these claims may be
successful.

    We could incur substantial costs and diversion of management resources in
the defense of any claims relating to proprietary rights, which could materially
adversely affect our business, financial condition, and results of operations.
Parties making these claims could secure a judgment awarding substantial damages
as well as injunctive or other equitable relief that could effectively block our
ability to license our products in the United States or abroad. Such a judgment
could have a material adverse effect on our business, financial condition and
results of operations. If a third party asserts a claim relating to proprietary
technology or information against us, we may seek licenses to the intellectual
property from the third party. We cannot be certain, however, that third parties
will extend licenses to us on commercially reasonable terms, or at all. If we
fail to obtain the necessary licenses or other rights, it could materially
adversely affect WWW Holdings' business, financial condition and results of
operations.

    DIFFICULTIES WWW HOLDINGS MAY ENCOUNTER WITH ITS GROWTH AND EXPANSION COULD
ADVERSELY AFFECT THE RESULTS OF WWW HOLDINGS' OPERATIONS.

    WWW Holdings' strategy will be to grow its membership at a rapid pace. This
strategy is likely to place a significant strain on WWW Holdings' resources
because of:

    - the need to manage relationships with various strategic partners,
      technology licensors, members and other third parties (based on
      September 30, 1999 data, WWW Holdings will have approximately 22
      significant strategic partners, approximately 5 significant licensors of
      technology material to the business, and approximately 2.85 million
      members upon consummation of the reorganization);

                                       21
<PAGE>
    - difficulties in hiring and retaining skilled personnel necessary to
      support WWW Holdings' business (based on September 30, 1999 data, WWW
      Holdings will have approximately 4,100 employees upon consummation of the
      reorganization);

    - increased demand on customer service and technical support;

    - pressures for the continued development of WWW Holdings' financial and
      information management systems; and

    - potential challenges associated with strategic acquisitions of
      complementary member accounts and businesses, if any, including systems
      integration difficulties and infrastructure strains on our ongoing
      business.

    Difficulties WWW Holdings may encounter in dealing successfully with the
above risks could adversely affect the results of WWW Holdings' operations.

    THE ABILITY OF WWW HOLDINGS STOCKHOLDERS TO EFFECT CHANGES IN CONTROL OF WWW
HOLDINGS WILL BE LIMITED.

    There are provisions in WWW Holdings' certificate of incorporation, bylaws,
and the Delaware General Corporation Law that could delay or impede the removal
of incumbent directors and could make more difficult a merger, tender offer, or
proxy contest involving WWW Holdings or could discourage a third party from
attempting to acquire control of WWW Holdings, even if these events would be
beneficial to the interests of the stockholders. In particular, the board of
directors could delay a change in control of WWW Holdings. In addition, WWW
Holdings' certificate of incorporation will authorize its board to provide for
the issuance of shares of preferred stock of WWW Holdings, in one or more
series, which the board of directors could issue without further stockholder
approval and with terms and conditions and rights, privileges and preferences
determined by the board of directors. There are no current plans to issue any
shares of preferred stock other than as a result of the conversion of the
EarthLink convertible preferred stock into WWW Holdings convertible preferred
stock as a result of the merger of EarthLink into WWW Holdings. Also, WWW
Holdings will be governed by Section 203 of the Delaware Corporation Law. In
general, Section 203 prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless specified conditions are met. These
factors could have the effect of delaying, deferring, or preventing a change of
control of WWW Holdings.

    SPRINT CORPORATION WILL BE ONE OF OUR PRINCIPAL STOCKHOLDERS AND IT CAN
EXERCISE SIGNIFICANT INFLUENCE OVER WWW HOLDINGS.

    Sprint Corporation will own approximately 4.41% of the common stock of WWW
Holdings immediately following the reorganization and it also will own preferred
stock that will be convertible into approximately 9.89% of WWW Holdings'
outstanding common stock immediately following the reorganization. Assuming that
Sprint fully exercises its right to maintain its current ownership levels,
Sprint will own approximately 27.8% of WWW Holdings, including approximately 10%
of the common stock of WWW Holdings. As a result in either case, Sprint will be
able to exercise significant influence over most matters requiring stockholder
approval, including the election of directors and the approval of significant
corporate matters, such as some types of change-of-control transactions. For
example, the approval by both of Sprint's representatives on the EarthLink board
of directors was required for EarthLink to go forward with the reorganization.
Sprint did not participate in, or materially seek to influence EarthLink's
management in its negotiations with, MindSpring, however, to the extent that WWW
Holdings engages in significant transactions in the future, we may be required
to seek Sprint's prior approval.

                                       22
<PAGE>

    Sprint's ownership of WWW Holdings preferred stock will permit it to elect
two of WWW Holdings directors, whose approval will be required for WWW Holdings
to undertake various activities. Also, without Sprint's consent, WWW Holdings
will not be able to enter into certain commercial relationships with competitors
of Sprint such as AT&T and MCI WorldCom. This may reduce or eliminate
opportunities for revenue growth. Further, Sprint's competitors may choose not
to engage in commercial relationships with us because of our close relationship
with Sprint, potentially significantly reducing our opportunities for revenue
growth. A more complete description of Sprint's rights and our related
obligations in this area may be found beginning on page 61 under the heading
"Sprint Governance Agreement."


    On October 5, 1999, Sprint announced that it entered into an agreement to be
acquired by MCI WorldCom Inc. We cannot guarantee you that WWW Holdings'
relationship with MCI WorldCom will provide WWW Holdings with the same benefits
that were expected to come from its relationship with Sprint.

    WE MAY BECOME REGULATED BY THE FEDERAL COMMUNICATIONS COMMISSION OR OTHER
GOVERNMENT AGENCIES, WHICH COULD SIGNIFICANTLY INCREASE OUR OVERHEAD COSTS AND
REQUIRE US TO MODIFY OUR GROWTH STRATEGIES AND OPERATING PLANS.

    As Internet service providers, EarthLink and MindSpring are not currently
directly regulated by the Federal Communications Commission or any other agency,
other than regulations applicable to businesses and publicly-traded companies
generally. In a report to Congress on April 10, 1998, the Federal Communications
Commission reaffirmed that Internet service providers should be classified as
unregulated "information service providers" rather than regulated
"telecommunications providers" under the terms of the Federal Telecommunications
Act of 1996.

    Nevertheless, Internet-related regulatory policies are continuing to
develop, and it is possible that we could be exposed to regulation in the
future. For example, in the same report to Congress, the Federal Communications
Commission stated its intention to consider whether to regulate voice and fax
telephony services provided over the Internet as "telecommunications" even
though Internet access itself would not be regulated. We cannot predict whether
in the future the Federal Communications Commission will modify its current
policies against regulation of Internet service providers.

    ACCESS CHARGES.  WWW Holdings also could be affected by any change in the
ability of customers to reach our network through a dial-up telephone call
without any additional charges. This practice has allowed Internet service
providers to offer flat-rate, non-usage sensitive pricing, and has been an
important reason for the growth in Internet use. Recently, the Federal
Communications Commission ruled that connections linking end users to their
Internet service providers are jurisdictionally interstate rather than local,
but the Federal Communications Commission did not subject such calling to the
access charges that apply to traditional telecommunications companies. Local
telephone companies assess access charges to long distance companies for the use
of the local telephone network to originate and terminate long-distance calls,
generally on a per-minute basis. WWW Holdings could be adversely affected by any
regulatory change that would result in application of access charges to Internet
service because this would substantially increase the cost of using the
Internet. However, the FCC Chairman has stated that he opposes Internet-related
access charges, and we believe that this development is unlikely, with one
possible exception that is not currently relevant to our business. Specifically,
there is substantial debate as to whether carrier access charges should apply to
Internet-based telephone services that substitute for conventional telephony. We
have no current plans to install gateway equipment and other telephony, and so
we do not believe we would be directly affected by these developments were they
to occur.

    POTENTIAL LIABILITY.  The law relating to the liability of Internet service
providers and on-line services companies for information carried on, stored on,
or disseminated through their network is unsettled, even with the recent
enactment of the Digital Millennium Copyright Act. While no one has

                                       23
<PAGE>
ever filed a claim against EarthLink or MindSpring relating to information
carried on, stored on, or disseminated through their network, someone may
file a claim of that type in the future and may be successful in imposing
liability on us. If that happens, we may have to spend significant amounts of
money to defend ourselves against these claims and, if we are not successful in
our defense, the amount of damages that we will have to pay may be significant.
Any costs that we incur as a result of defending these claims or the amount of
liability that we may suffer if our defense is not successful could materially
adversely affect our business, financial condition and results of operations.

    If, as the law in this area develops, we become liable for information
carried on, stored on, or disseminated through our network, we may decide to
take actions to reduce our exposure to this type of liability. This may require
us to spend significant amounts of money for new equipment and may also require
us to discontinue offering some of our products or services.

    OTHER ISSUES.  Due to the increasing popularity and use of the Internet, it
is possible that additional laws and regulations may be adopted with respect to
the Internet, covering issues such as:

    - content;

    - privacy;

    - access to some types of content by minors;

    - pricing;

    - bulk e-mail or "spam;"

    - encryption standards;

    - consumer protection;

    - electronic commerce;

    - taxation;

    - copyright infringement; and

    - other intellectual property issues.

We cannot predict the impact, if any, that any future regulatory changes or
developments may have on our business, financial condition, and results of
operations. Changes in the regulatory environment relating to the Internet
access industry, including regulatory changes that directly or indirectly affect
telecommunication costs or increase the likelihood or scope of competition from
regional telephone companies or others, could have a material adverse effect on
our business, financial condition and results of operations.

    FAILURE TO ACHIEVE YEAR 2000 COMPLIANCE MAY HAVE ADVERSE EFFECTS ON THE
OPERATIONS AND FINANCIAL PERFORMANCE OF EARTHLINK, MINDSPRING AND WWW HOLDINGS.

    Our failure, or the failure of third parties on which we rely, to adequately
address Year 2000 readiness issues could result in an interruption, or a
failure, of some normal business activities or operations. Presently, we believe
that the primary risks that we face with regard to the Year 2000 are those
arising from third-party services or products.

    In particular, EarthLink and MindSpring depend heavily on a significant
number of third-party vendors to provide both network services and equipment. A
significant Year 2000-related disruption to these network services or equipment
could cause our customers to consider seeking alternate providers or cause an
unmanageable burden on customer service and technical support. This in turn
could materially and adversely affect WWW Holdings' results of operations,
liquidity and financial condition.

                                       24
<PAGE>
    Furthermore, our business depends on the continued operation of, and
widespread access to, the Internet. To the extent that the normal operation of
the Internet is disrupted by Year 2000 problems, or if a large portion of our
customers are unable to access the Internet due to Year 2000-related issues in
connection with their own systems, WWW Holdings' results of operations,
liquidity and financial condition could be materially and adversely affected.

    MindSpring has completed its assessment of the Year 2000 readiness of its
internally-developed and third-party supplied software, computer technology and
other services. Based upon the results of this assessment, MindSpring believes
that its own systems, including the components of its systems provided by
third-party vendors, are Year 2000 compliant. MindSpring anticipates that all of
its material third party providers are Year 2000 compliant and that all of its
other providers are substantially compliant. As of November 30, 1999, MindSpring
had incurred expenses of approximately $600,000 in connection with the
implementation of its Year 2000 compliance program. These costs were expensed as
incurred. MindSpring estimates that it will incur minimal expenses through the
remainder of the Year 2000 compliance program. To the extent it can be
determined at this time, MindSpring has not suffered any Year 2000 problems with
its computer and business systems, nor did any of its significant third-party
vendors, that materially affect MindSpring's business.

    EarthLink has incurred insignificant amounts in its efforts to make its
systems Year 2000 compliant and does not anticipate incurring any further
material expenditures as part of these efforts. To the extent it can be
determined at this time, Earthlink has not suffered any Year 2000 problems with
its computer and business systems, nor did any of its significant third-party
vendors, that materially affect EarthLink's business.

    IF APPLE'S INVESTMENT IN EARTHLINK IS UNWOUND BECAUSE OF LACK OF REGULATORY
APPROVAL PRIOR TO MARCH 31, 2000, EARTHLINK MAY LOSE SOME OF THE VALUE OF ITS
STRATEGIC RELATIONSHIP WITH APPLE.

    On January 4, 2000, a subsidiary of Apple Computer, Inc. purchased
$200 million of EarthLink's series C convertible preferred stock. This purchase,
however, closed in escrow pending the termination or expiration of the required
regulatory waiting period imposed by the Hart-Scott-Rodino Antitrust
Improvements Act. If the waiting period does not expire or terminate prior to
March 31, 2000, this investment will be unwound, Apple's investment will be
returned to Apple and the series C convertible preferred stock will be
cancelled. If this occurs, WWW Holdings may lose the benefits of the strategic
relationship with Apple. In particular, without an investment relationship,
Apple may not promote WWW Holdings' services to Apple customers as vigorously as
it otherwise would. Also, without an investment relationship, Apple would not
have the right, as the holder of WWW Holdings' series C convertible preferred
stock, to elect a director to WWW Holdings' board. Without an Apple member on
WWW Holdings' board, WWW Holdings may be deprived of the business expertise and
prestige an Apple representative could bring to the company. Please carefully
read the section of this joint proxy statement/prospectus titled "Recent
Development--Strategic Alliance with Apple Computer, Inc."

    IF WWW HOLDINGS IS UNABLE TO RAISE CAPITAL ON ACCEPTABLE TERMS, WWW HOLDINGS
MAY BE REQUIRED TO MODIFY ITS GROWTH STRATEGIES AND OPERATING PLANS.

    After the reorganization, we expect that WWW Holdings will need capital to
continue to enhance and develop the companies' combined network to maintain our
competitive position and continue to meet the increasing demands for service
quality, availability, and competitive pricing. We may also need to spend
significant amounts of cash to:

    - fund growth, operating losses and increases in expenses;

    - take advantage of unanticipated major strategic alliances or other special
      marketing opportunities;

    - acquire complementary businesses or assets;

                                       25
<PAGE>
    - develop new products or services; or

    - otherwise respond to unanticipated developments or competitive pressures.

    If we do not have enough cash on hand, cash generated from our operations,
or cash available under our credit facility with Sprint to meet these cash
requirements, we will need to seek alternative sources of financing to carry out
our growth and operating plans. We may not be able to raise needed cash on terms
acceptable to us or at all. Financings may be on terms that are dilutive or
potentially dilutive to our stockholders. If alternative sources of financing
are required, but are insufficient or unavailable on terms that are acceptable
to us, we will be required to modify our growth and operating plans to the
extent of available funding and attempt to attain profitability in our existing
operations.

    MindSpring also has a credit agreement with a group of financial
institutions led by First Union National Bank for a $100 million secured
revolving credit facility. There are no amounts currently outstanding under this
facility. Unless the parties successfully negotiate an amendment to this credit
agreement, the reorganization will give the bank the right to terminate the
credit agreement. If the MindSpring credit agreement with First Union is not
re-negotiated, WWW Holdings may have difficulty in obtaining alternative funds,
if needed. Currently, all amounts that MindSpring may borrow under this credit
agreement are secured by all of MindSpring's assets. Should we decide to
re-negotiate this agreement, it is likely that First Union will require us to
pledge all of the assets of WWW Holdings as security for any amounts borrowed
and WWW Holdings' business activities would likely be subject to numerous
restrictive covenants contained in the credit agreement. These conditions could
place constraints on our ability to conduct our business.

    WWW HOLDINGS' STOCK PRICE MAY FLUCTUATE SIGNIFICANTLY REGARDLESS OF WWW
HOLDINGS' ACTUAL OPERATING PERFORMANCE.

    There is no current public market for WWW Holdings common stock. Immediately
following completion of the reorganization, WWW Holdings common stock will be
listed for trading on The Nasdaq National Market. The trading price of WWW
Holdings' common stock is likely to be highly volatile. WWW Holdings' stock
price could be subject to wide fluctuations in response to a variety of factors,
including:

    - actual or anticipated variations in quarterly operating results;

    - announcements of technological innovations;

    - new products or services offered by WWW Holdings or its competitors;

    - changes in financial estimates by securities analysts;

    - conditions or trends in the Internet services industry and the portal and
      community services segment in particular;

    - WWW Holdings' announcement of significant acquisitions, strategic
      partnerships, joint ventures or capital commitments;

    - additions or departures of key personnel;

    - sales of common stock; and

    - other events that may be beyond WWW Holdings' control.

    In addition, The Nasdaq National Market, where most publicly-held Internet
companies are traded, has recently experienced extreme price and volume
fluctuations. These fluctuations often have been unrelated or disproportionate
to the operating performance of these companies. The trading prices of many
Internet companies' stocks are, or recently have been, at or near historical
highs and these trading prices and multiples are substantially above historical
levels. These trading prices and

                                       26
<PAGE>
multiples may not be sustainable. These broad market and industry factors may
materially adversely affect the market price of WWW Holdings' common stock,
regardless of WWW Holdings' actual operating performance. In the past, following
periods of volatility in the market price of an individual company's securities,
securities class action litigation often has been instituted against that
company. This type of litigation, if instituted, could result in substantial
costs and a diversion of management's attention and resources.

    SALES OF SUBSTANTIAL AMOUNTS OF WWW HOLDINGS' COMMON STOCK IN THE OPEN
MARKET COULD DEPRESS WWW HOLDINGS' STOCK PRICE.

    If WWW Holdings' stockholders sell substantial amounts of WWW Holdings'
common stock in the public market following consummation of the reorganization,
including shares issued on the exercise of outstanding options and warrants, the
market price of WWW Holdings' common stock could fall. These sales might also
make it more difficult for WWW Holdings to sell equity or equity related
securities at a time and price that WWW Holdings would deem appropriate.

    Sales of a large number of shares of common stock in the public market
following the consummation of the reorganization, or even the belief that such
sales could occur, could cause a drop in the market price of WWW Holdings'
common stock and could impair WWW Holdings' ability to raise capital through
offerings of WWW Holdings' equity securities. Immediately after the
reorganization, there will be approximately 117 million shares of WWW Holdings'
common stock outstanding. All of the shares issued to EarthLink and MindSpring
stockholders will be freely tradable without restrictions or further
registration under the Securities Act of 1933, unless such shares are held by
any WWW Holdings "affiliate" or any "affiliate" of EarthLink or MindSpring prior
to the reorganization, as that term is defined under the Securities Act of 1933.
The term "affiliate" would include directors, executive officers and some
significant stockholders.

                         THE EARTHLINK SPECIAL MEETING

DATE AND PURPOSE OF THE SPECIAL MEETING

    The special meeting of EarthLink stockholders is scheduled to be held on
February 4, 2000, at 8:00 a.m., local time, in the Town Hall Conference Room at
2947 Bradley Street, Pasadena, California. It may be adjourned or postponed to
another date and/or place for proper purposes. The purpose of the meeting is to
consider and vote upon a proposal to adopt the reorganization agreement. The
EarthLink stockholders also might be asked to vote upon a proposal to adjourn
the EarthLink special meeting for the purpose, among others, of allowing
additional time for the solicitation of additional votes to adopt the
reorganization agreement.

RECORD DATE FOR THE SPECIAL MEETING AND WHO IS ENTITLED TO VOTE AT THE SPECIAL
  MEETING

    RECORD DATE.  The EarthLink board has fixed the close of business on
December 20, 1999, as the record date for the determination of the EarthLink
stockholders entitled to receive notice of and to vote at the EarthLink special
meeting. A complete list of stockholders entitled to vote at the meeting will be
open to examination by the stockholders, during regular business hours, for a
period of ten days before the meeting at the principal executive offices of
EarthLink at 3100 New York Drive, Pasadena, California. As of the record date,
32,928,892 shares of EarthLink common stock were outstanding and entitled to
vote on the adoption of the reorganization agreement.

    VOTING RIGHTS.  Each EarthLink stockholder is entitled to one vote for each
share of EarthLink common stock held on the record date with regard to the
proposal to adopt the reorganization agreement and with regard to each other
matter that may properly come before the EarthLink special meeting. The vote of
the holders of EarthLink's preferred stock is not required for adoption of the
reorganization agreement.

    QUORUM REQUIREMENTS.  A majority of the EarthLink common stock outstanding
and entitled to vote, represented in person or by proxy, constitutes a quorum
for consideration of each matter at the EarthLink special meeting. If a quorum
is not present at the EarthLink special meeting, management will adjourn it in
order to solicit additional proxies.

    VOTE REQUIRED.  The affirmative vote of the holders of a majority of the
outstanding shares of EarthLink common stock entitled to vote at the EarthLink
special meeting will be sufficient to adopt the reorganization agreement.

    ABSTENTIONS, FAILURES TO VOTE, AND BROKER NON-VOTES.  Abstentions may be
specified with respect to the proposal being considered at the EarthLink special
meeting. A properly executed proxy marked "ABSTAIN" will be counted as present
for purposes of determining whether there is a quorum. Because the affirmative
votes of a majority of the outstanding shares of the EarthLink common stock are
required for adoption of the reorganization agreement, a proxy marked "ABSTAIN"
with respect to the reorganization agreement will have the effect of a vote
"AGAINST" the reorganization agreement. In addition, the failure of an EarthLink
stockholder to return a proxy or vote in person at the EarthLink special meeting
or by other permitted means will have the effect of a vote "AGAINST" the
adoption of the reorganization agreement. Brokers who hold shares in street name
for customers have the authority to vote on "routine" proposals when they have
not received instructions from beneficial owners. Brokers are precluded from
exercising their voting discretion with respect to proposals for non-routine
matters such as the adoption of the reorganization agreement. Thus, absent
specific instructions from the beneficial owner of shares of EarthLink common
stock, brokers are not permitted to vote these shares with respect to the
adoption of the reorganization agreement. Since the affirmative vote described
above is required for adoption of the reorganization agreement, a broker
non-vote will have the effect of a vote "AGAINST" adoption of the reorganization
agreement.

                                       28
<PAGE>
    BECAUSE ADOPTION OF THE REORGANIZATION AGREEMENT REQUIRES THE AFFIRMATIVE
VOTE OF A MAJORITY OF THE VOTES ENTITLED TO BE CAST BY THE HOLDERS OF EARTHLINK
COMMON STOCK AT THE EARTHLINK SPECIAL MEETING, ABSTENTIONS AND BROKER NON-VOTES
WILL HAVE THE SAME EFFECT AS NEGATIVE VOTES. THE FAILURE TO VOTE YOUR SHARES
WILL ALSO HAVE THE SAME EFFECT AS A NEGATIVE VOTE. ACCORDINGLY, THE EARTHLINK
BOARD URGES YOU TO COMPLETE, DATE AND SIGN THE ACCOMPANYING PROXY AND RETURN IT
PROMPTLY IN THE ENCLOSED, POSTAGE-PAID ENVELOPE, OR TO CAST YOUR VOTE ON THE
INTERNET OR BY TELEPHONE IN ACCORDANCE WITH THE INSTRUCTIONS ON THE PROXY FORM.

    As of the record date, EarthLink directors and executive officers owned
approximately 10.1 million shares of EarthLink common stock, or approximately
31% of the shares entitled to vote at the EarthLink special meeting. It is
currently expected that each director or executive officer will vote the shares
of EarthLink common stock beneficially owned by him for adoption of the
reorganization agreement.


    Some of EarthLink's stockholders, including members of management and the
board of directors, who collectively own approximately 29.3% of the outstanding
common stock of EarthLink, have entered into agreements with MindSpring in which
they have agreed to vote their shares "FOR" adoption of the reorganization
agreement. See "EarthLink and MindSpring Stockholder Agreements" on page 34 for
more information about these agreements.


VOTING BY PROXY AND HOW TO REVOKE YOUR PROXY

    You may vote shares either in person or by duly authorized proxy. In
addition, you may vote your shares by telephone or through the Internet by
following the instructions provided on the enclosed proxy form. You may use the
proxy accompanying this joint proxy statement/prospectus if you are unable to
attend the EarthLink special meeting in person or if you wish to have your
shares voted by proxy even if you do attend the EarthLink special meeting. You
may revoke any proxy given by you in response to this solicitation at any time
before the proxy is voted at the EarthLink special meeting by delivering a
written notice of revocation, by delivery to EarthLink a subsequently dated,
properly executed proxy or by attending the EarthLink special meeting and
electing to vote in person. Your attendance at the EarthLink special meeting, by
itself, will not constitute a revocation of a proxy. You should address any
written notices of proxy revocation to: EarthLink Network, Inc., at 3100 New
York Drive, Pasadena, California 91107, Attention: Corporate Secretary.

    All shares represented by effective proxies on the accompanying form of
EarthLink proxy received by EarthLink at or before the EarthLink special
meeting, and not revoked before they are exercised, will be voted at the
EarthLink special meeting in accordance with their terms. If no instructions are
given, the EarthLink proxies will be voted "FOR" the adoption of the
reorganization agreement and at the discretion of the proxies on any other
matters that properly come before the EarthLink special meeting. The EarthLink
board is not aware of any other matters to be presented at the EarthLink special
meeting other than matters incidental to the conduct of the EarthLink special
meeting.

SOLICITATION OF PROXIES

    EarthLink will bear the entire cost of the solicitation of proxies for the
EarthLink special meeting and of the printing, mailing and filing of this joint
proxy statement/prospectus. In addition to the solicitation of proxies by mail,
officers, directors, employees and agents of EarthLink may solicit proxies by
correspondence, telephone, telegraph, telecopy or other electronic means, or in
person, but without extra compensation. EarthLink has retained Corporate
Investor Communications, Inc., a proxy solicitation firm, to assist it in the
solicitation of proxies for the EarthLink special meeting at a cost of
approximately $5,000 plus reimbursement of reasonable out-of-pocket expenses.
EarthLink will request banks, brokers and other record holders to send proxies
and proxy materials to the beneficial owners of EarthLink common stock and
secure their voting instructions and will reimburse their reasonable charges and
expenses incurred in forwarding the proxies and proxy materials. Further
solicitation of proxies may be made by telephone or in person with some
EarthLink stockholders following the original solicitation. All further
solicitation will be made by officers and other employees of EarthLink who will
not be additionally compensated for their activities.

                         THE MINDSPRING SPECIAL MEETING

DATE AND PURPOSE OF THE SPECIAL MEETING


    The special meeting of MindSpring's stockholders is scheduled to be held on
February 4, 2000, at 11:00 a.m., local time, at the Georgia Center for Advanced
Telecommunications Technology (GCATT), Auditorium, 250 14(th) Street, NW,
Atlanta, Georgia. It may be adjourned or postponed to another date and/or place
for proper purposes. The purpose of the MindSpring special meeting is to
consider and vote upon a proposal to adopt the reorganization agreement. The
MindSpring stockholders also might be asked to vote upon a proposal to adjourn
the MindSpring special meeting for the purpose, among others, of allowing
additional time for the solicitation of additional votes to adopt the
reorganization agreement.


RECORD DATE FOR THE SPECIAL MEETING AND WHO IS ENTITLED TO VOTE AT THE SPECIAL
  MEETING


    RECORD DATE.  The MindSpring board has fixed the close of business on
December 20, 1999, as the record date for the determination of the MindSpring
stockholders entitled to receive notice of and to vote at the MindSpring special
meeting. A complete list of stockholders entitled to vote at the meeting will be
open to examination by the stockholders during regular business hours, for a
period of ten days before the MindSpring special meeting at the principal
executive offices of MindSpring, 1430 West Peachtree Street, NW, Suite 400,
Atlanta, Georgia 30309. As of the record date, 63,644,368 shares of MindSpring
common stock were outstanding and entitled to vote on the adoption of the
reorganization agreement.


    VOTING RIGHTS.  Each MindSpring stockholder is entitled to one vote for each
share of MindSpring common stock held on the record date with regard to the
proposal to adopt the reorganization agreement and with regard to each other
matter that may properly come before the MindSpring special meeting.

    QUORUM REQUIREMENTS.  A majority of the MindSpring common stock outstanding
and entitled to vote, represented in person or by proxy, constitutes a quorum
for consideration of each matter at the MindSpring special meeting. If a quorum
is not present at the MindSpring special meeting, management will adjourn it in
order to solicit additional proxies.

    VOTE REQUIRED.  The affirmative vote of the holders of a majority of the
outstanding shares of MindSpring common stock entitled to vote at the MindSpring
special meeting will be sufficient to adopt the reorganization agreement.

    ABSTENTIONS, FAILURES TO VOTE, AND BROKER NON-VOTES.  Abstentions may be
specified with respect to the proposal being considered at the MindSpring
special meeting. A properly executed proxy marked "ABSTAIN" will be counted as
present for purposes of determining whether there is a quorum. Because the
affirmative votes of a majority of the outstanding shares of the MindSpring
common stock are required for adoption of the reorganization agreement, a proxy
marked "ABSTAIN" with respect to the reorganization agreement will have the
effect of a vote "AGAINST" the adoption of the reorganization agreement. In
addition, the failure of a MindSpring stockholder to return a proxy or vote in
person at the MindSpring special meeting or by other permitted means will have
the effect of a vote "AGAINST" the adoption of the reorganization agreement.
Brokers who hold shares in street name for customers have the authority to vote
on "routine" proposals when they have not received instructions from beneficial
owners. Brokers are precluded from exercising their voting discretion with
respect to proposals for non-routine matters such as the adoption of the
reorganization agreement. Thus, absent specific instructions from the beneficial
owner of shares of MindSpring common stock, brokers are not permitted to vote
these shares with respect to the adoption of the reorganization agreement. Since
the affirmative vote described above is required for adoption of the
reorganization agreement, a broker non-vote will have the effect of a vote
"AGAINST" the adoption of the reorganization agreement.

    BECAUSE ADOPTION OF THE REORGANIZATION AGREEMENT REQUIRES THE AFFIRMATIVE
VOTE OF A MAJORITY OF THE VOTES ENTITLED TO BE CAST BY THE HOLDERS OF MINDSPRING
COMMON STOCK AT THE MINDSPRING SPECIAL MEETING, ABSTENTIONS AND BROKER NON-VOTES
WILL HAVE THE SAME EFFECT AS NEGATIVE VOTES. THE FAILURE TO VOTE YOUR SHARES
ALSO WILL HAVE THE SAME EFFECT AS A NEGATIVE VOTE. ACCORDINGLY, THE MINDSPRING
BOARD URGES YOU TO COMPLETE, DATE AND SIGN THE ACCOMPANYING PROXY AND RETURN IT
PROMPTLY IN THE ENCLOSED, POSTAGE-PAID ENVELOPE OR TO CAST YOUR VOTE ON THE
INTERNET OR BY TELEPHONE IN ACCORDANCE WITH THE INSTRUCTIONS ON THE PROXY FORM.

    As of the record date, MindSpring directors and executive officers owned
approximately 4.9 million shares of MindSpring common stock, or approximately
7.8% of the shares entitled to vote at the MindSpring special meeting. It is
currently expected that each director or executive officer will vote the shares
of MindSpring common stock beneficially owned by him "FOR" adoption of the
reorganization agreement.


    Some of MindSpring's stockholders, including members of management and the
board of directors, who collectively own approximately 24.5% of the outstanding
common stock of MindSpring, have entered into agreements with EarthLink in which
they have agreed to vote their shares "FOR" adoption of the reorganization
agreement. See "EarthLink and MindSpring Stockholder Agreements" on page 34 for
more information about these agreements.


VOTING BY PROXY AND HOW TO REVOKE YOUR PROXY

    You may vote shares either in person or by duly authorized proxy. In
addition, you may vote your shares by telephone or through the Internet by
following the instructions provided in the enclosed proxy form. You may use the
proxy accompanying this joint proxy statement/prospectus if you are unable to
attend the MindSpring special meeting in person or if you wish to have your
shares voted by proxy even if you do attend the MindSpring special meeting. You
may revoke any proxy given by you in response to this solicitation at any time
before the proxy is voted at the MindSpring special meeting by delivering a
written notice of revocation, by delivering to MindSpring a subsequently dated,
properly executed proxy or by attending the MindSpring special meeting and
electing to vote in person. Your attendance at the MindSpring special meeting,
by itself, will not constitute a revocation of a proxy. You should address any
written notices of proxy revocation to: MindSpring Enterprises, Inc., 1430 West
Peachtree Street, NW, Suite 400, Atlanta, Georgia 30309, Attention: Corporate
Secretary.

    All shares represented by effective proxies on the accompanying form of
MindSpring proxy received by MindSpring at or before the MindSpring special
meeting, and not revoked before they are exercised, will be voted at the
MindSpring special meeting in accordance with their terms. If no instructions
are given, the MindSpring proxies will be voted "FOR" the adoption of the
reorganization agreement and at the discretion of the proxies on any other
matters that properly come before the MindSpring special meeting. The MindSpring
board is not aware of any other matters to be presented at the MindSpring
special meeting other than matters incidental to the conduct of the MindSpring
special meeting.

SOLICITATION OF PROXIES

    MindSpring will bear the entire cost of the solicitation of proxies for the
MindSpring special meeting and of the printing, mailing and filing of this joint
proxy statement/prospectus. In addition to the solicitation of proxies by mail,
officers, directors, employees and agents of MindSpring may solicit proxies by
correspondence, telephone, telegraph, telecopy or other electronic means, or in

Investor Communications, Inc., a proxy solicitation firm, to assist it in the
solicitation of proxies for the MindSpring special meeting at a cost of
approximately $7,000 plus reimbursement of reasonable out-of-pocket expenses.
MindSpring will request banks, brokers and other record holders to send proxies
and proxy materials to the beneficial owners of MindSpring common stock and
secure their voting instructions and will reimburse their reasonable charges and
expenses incurred in forwarding the proxies and proxy materials. Further
solicitation of proxies may be made by telephone or in person with some
MindSpring stockholders following the original solicitation. All further
solicitation will be made by officers and other employees of MindSpring who will
not be additionally compensated for their activities.

EARTHLINK AND MINDSPRING STOCK OPTION AGREEMENTS

    The following information relating to the stock option agreements is not
intended to be a complete description of all of the information relating to the
stock option agreements, but is intended to include the material terms of the
stock option agreements.

    As a condition to the execution by EarthLink and MindSpring of the
reorganization agreement, EarthLink and MindSpring entered into stock option
agreements with one another under which EarthLink has the option to acquire up
to 19.9% of the outstanding MindSpring common stock and MindSpring has the
option to acquire up to 19.9% of the outstanding EarthLink common stock, all
subject to the terms and conditions described below, among others.

    The terms and conditions of the stock option agreements are parallel, except
as noted below, and include the following:

    The option granted under the stock option agreement may only be exercised if
the party exercising the option is not in material breach of the reorganization
agreement or the stock option agreement and one of the following events occurs:

    - the reorganization agreement is terminated by the option holder because
      the other party's board of directors amended, modified, withdrew,
      conditioned or qualified its recommendation that its stockholders adopt
      the reorganization agreement or because the other party's board of
      directors has recommended that its stockholders adopt an agreement with a
      third party to sell itself or a significant amount of its stock or assets
      to the third party;

    - the party that granted the option terminates the reorganization agreement
      after its board of directors withdraws its recommendation that its
      stockholders adopt the reorganization agreement as permitted in some
      circumstances under the reorganization agreement; or


    - the reorganization agreement is terminated and a termination fee becomes
      payable under the terms of the reorganization agreement. See page 75 for a
      more detailed description of the circumstances under which the
      reorganization agreement may be terminated or a termination fee becomes
      payable.


    The option holder will have 90 days from the occurrence of one of these
events to give notice of its decision to exercise its option. Each option will
expire if it is not exercised before:

    - the mergers of EarthLink and MindSpring into WWW Holdings occur; or

    - eighteen months pass after the occurrence of an event that makes the
      option exercisable.

    The exercise price under MindSpring's option to acquire EarthLink common
stock is $43.50 per share and the exercise price under EarthLink's option to
acquire MindSpring common stock is $32.875 per share. In either case, the option
holder's profit upon the ultimate sale of the underlying common stock or on
exercise of the option for cash plus any termination fee received pursuant to
the reorganization agreement, as described below, cannot exceed $80,000,000. The
shares subject to the option will be adjusted to account for stock dividends,
stock splits, mergers, share exchanges and the like. Accordingly, the option
exercise prices will be adjusted to account for stock dividends, stock splits,
mergers, shares exchanges or the like by multiplying the exercise price by a
fraction, the numerator of which is equal to the number of shares subject to the
option prior to the event requiring the adjustment and the denominator of which
is equal to the number of shares that are subject to the option following the
event requiring the adjustment. For example, if the option holder could have
purchased 1,000 shares under the option for $32.875 per share and the party
granting the option engages in a 3-for-1 stock split, the number of shares
subject to the option will become 3,000 and the new exercise price will be
$32.875 multiplied by 1/3, or approximately $10.958 per share.

                                       33
<PAGE>
    The party granting the option has the choice of either issuing the shares of
common stock for which the option is being exercised, paying cash instead of
issuing the common stock, or delivering any combination of cash and common
stock. The cash amount would be determined by subtracting the option exercise
price from an amount equal to the greater of the average closing price for the
common stock for the ten trading days prior to the exercise of the option and
the per share consideration for the common stock proposed to be paid in a
pending third-party proposal to acquire all or a significant part of the common
stock or assets of the party granting the option, and then multiplying that
amount by the number of shares of common stock for which cash is being paid. The
number of shares of common stock issued as a result of the exercise of the
option may not be less than 5% of the total number of shares of outstanding
common stock of the party granting the option immediately after the issuance of
the shares pursuant to the option.

    If the option holder exercises the option, it has the right to cause the
party that granted the option to register the shares of common stock that it
purchases under the Securities Act of 1933, so long as the shares to be
registered equal at least 2% of the outstanding shares of the party that granted
the option on a fully diluted basis. The option holder has no right to cause the
registration of any shares of common stock that may be sold under Rule 144(k) of
the Securities Act of 1933, which generally permits sales of securities by
persons who have not been affiliated with the issuer of those securities for at
least three months prior to the sale, so long as at least two years have passed
since the securities were acquired from the issuer or one of its affiliates.

EARTHLINK AND MINDSPRING STOCKHOLDER AGREEMENTS

    The following information relating to the stockholder agreements is not
intended to be a complete description of all of the information relating to the
stockholder agreements, but is intended to include the material terms of the

voting rights in the common stock to do the same. The obligations under the
stockholder agreements terminate automatically upon the termination of the
reorganization agreement.

stockholder agreements for the benefit of MindSpring: Sprint, Sidney Azeez,
Charles G. Betty, Sky D. Dayton, Richard D. Edmiston, William S. Heys, Grayson
L. Hoberg, Robert M. Kavner, Linwood A. Lacy, Jr., Kevin M. O'Donnell, Reed E.

stockholder agreements for the benefit of EarthLink: ITC Service Company, Inc.,
Charles M. Brewer, Michael S. McQuary, Campbell B. Lanier, III, William H.
Scott, III, Lance Weatherby, Gregory J. Stromberg and O. Gene Gabbard.

WHAT EARTHLINK STOCKHOLDERS WILL RECEIVE IN THE REORGANIZATION

    Each share of EarthLink common stock, EarthLink series A convertible
preferred stock, EarthLink series B convertible preferred stock and EarthLink
series C convertible preferred stock issued and

                                       34
<PAGE>
outstanding at the effective time of the merger of EarthLink into WWW Holdings
will be converted automatically into 1.615 shares of WWW Holdings common stock,
WWW Holdings series A convertible preferred stock, WWW Holdings series B
convertible preferred stock or WWW Holdings series C convertible preferred
stock, as the case may be. Also at the effective time of the merger of EarthLink
into WWW Holdings, each option, warrant or other right to purchase shares of
EarthLink common stock will be converted automatically into a new option,
warrant or other right to purchase a number of shares of WWW Holdings common
stock equal to the number of shares of EarthLink common stock subject to the
option, warrant or other right multiplied by 1.615. The per share exercise price
of the new option, warrant or other right will be divided by 1.615. Otherwise,
the terms and conditions of the option, warrant or other right will remain
unchanged.

WHAT MINDSPRING STOCKHOLDERS WILL RECEIVE IN THE REORGANIZATION

    Each share of MindSpring common stock issued and outstanding at the
effective time of the merger of MindSpring into WWW Holdings will be converted
automatically into one share of WWW Holdings common stock. Also at the effective
time of the merger of MindSpring into WWW Holdings, each option, warrant or
other right to purchase shares of MindSpring common stock will be converted
automatically into an option, warrant or other right to purchase the same number
of shares of WWW Holdings common stock on the same terms and conditions.

CASH PAYMENTS FOR FRACTIONAL SHARES OF WWW HOLDINGS COMMON STOCK

    If the conversion of EarthLink shares of common stock into shares of WWW
Holdings common stock results in any former EarthLink stockholder being entitled
to receive a fraction of a share of WWW Holdings common stock, no fraction of a
share of WWW Holdings common stock will be delivered. Rather than receiving a
fraction of a share, former EarthLink common stockholders will receive a cash
payment, without interest and subject to the payment of applicable withholding
taxes, based on the mean of the high and low sales prices of WWW Holdings common
stock as reported on The Nasdaq National Market on the first full day on which
the WWW Holdings common stock is traded on The Nasdaq National Market.

EFFECT OF THE REORGANIZATION ON HOLDERS OF MINDSPRING CONVERTIBLE SUBORDINATED
  NOTES

    As required by the indentures governing the 5% convertible subordinated
notes due 2006 issued by MindSpring in April 1999, upon completion of the
reorganization, WWW Holdings will adopt the indentures and the notes will become
convertible into shares of common stock of WWW Holdings. Completion of the
reorganization will constitute a "change in control" of MindSpring under the
indentures. Therefore, after the reorganization is completed, each holder of
notes will have the option to require WWW Holdings to repurchase that holder's
notes at a repurchase price of 100% of the principal amount plus accrued
interest to the date of repurchase. The reorganization agreement provides that
the repurchase price for the notes will be paid in cash. A holder that chooses
not to have the notes repurchased will thereafter hold convertible subordinated
notes of WWW Holdings.

BACKGROUND AND NEGOTIATION OF THE REORGANIZATION

    Mr. Betty, Mr. Dayton and Mr. Brewer have known each other for several
years, and have encountered one another in a variety of business and industry
settings on a fairly regular basis. Beginning on May 26, 1999, Mr. Betty,
Mr. Dayton and Mr. Brewer had several conversations regarding whether they had
any potential interest in a business combination between EarthLink and
MindSpring. On May 31, 1999, Mr. Betty, Mr. Brewer, Mr. McQuary and Mr. Dayton
met at Mr. Brewer's home in Atlanta for preliminary discussions of the concept
of a potential combination of the two companies, including overall structure,
company philosophies, business strategy and general conceptual matters. No
agreement on any terms was reached at that meeting.

                                       35
<PAGE>
    On June 2, 1999, another meeting among Mr. Betty, Mr. Brewer and Mr. Dayton
was held at Mr. Dayton's home in Los Angeles for further preliminary discussions
regarding a potential business combination between EarthLink and MindSpring.
This meeting included additional discussions regarding overall structure,
company philosophies, overall business strategy and general conceptual matters
in connection with a possible merger or other type of business combination
between the companies. The participants were unable to agree upon an exchange
ratio, the management structure of the new company or the name of the new
company and did not reach agreement on any other terms.

    On June 3 and June 4, 1999, Mr. Betty and Mr. Brewer continued their
discussions via telephone, during which additional details of possible terms of
a business combination were discussed, including among other areas relative
equity ownership, composition of the board of directors and executive management
positions. During the June 4 telephone call, Mr. Brewer expressed his view that
the parties could not reach agreement on the general terms of a proposed merger
between EarthLink and MindSpring. Thereafter, the parties mutually agreed to
terminate any further discussions regarding a possible business combination or
other relationship.

    In early June 1999, MindSpring also received an unsolicited inquiry from
another company regarding a potential business combination. MindSpring engaged
Donaldson, Lufkin and Jenrette Securities Corporation to provide financial
advice in connection with evaluating this inquiry and potential strategic
alternatives. Donaldson, Lufkin and Jenrette proceeded to identify various
potential transaction candidates, and to seek indications of interest from
several parties in pursuing a business combination with MindSpring. Between June
and September 1999, MindSpring had discussions with several of these parties
regarding possible business combinations or strategic transactions. No
agreements were reached other than the agreement with EarthLink.

    On July 9 and July 10, 1999, Mr. Brewer and Mr. Betty reopened preliminary
discussions and discussed by telephone a proposed "merger of equals" between the
companies. They did not reach any agreement on any terms during these
discussions, and MindSpring continued to consider alternative transactions.

    On July 12, 1999, Mr. Brewer transmitted to Mr. Betty written terms of a
possible merger that Mr. Brewer was willing to discuss and pursue, based on an
acquisition of one company by the other rather than a merger of equals.
Mr. Betty informed Mr. Brewer that his written proposed terms of merger were
unacceptable, and that a merger under the proposed terms would not take place.
At that time, Mr. Betty and Mr. Brewer once again mutually agreed to terminate
any further discussions of a business combination.

    During July and August, EarthLink engaged in discussions with several other
entities regarding potential business combinations and other strategic
alternatives. These discussions did not result in any agreements.

    In early August 1999, Mr. Betty telephoned Mr. Brewer to discuss possibly
reinitiating merger discussions, to which Mr. Brewer agreed. On August 9, 1999,
Mr. Betty and Mr. Brewer held a meeting at Mr. Brewer's home in Atlanta to
discuss a possible merger of equals between EarthLink and MindSpring. Although
no agreement on any terms of a proposed transaction was reached at that meeting,
Mr. Betty and Mr. Brewer agreed to continue discussing the possibility of a
merger and possible terms of a transaction, and to discuss the same with their
respective investment banking and financial advisory firms--Credit Suisse First
Boston for EarthLink and Donaldson, Lufkin & Jenrette for MindSpring.

    On August 17, 1999, Credit Suisse First Boston on behalf of EarthLink
transmitted a preliminary proposed term sheet setting forth the principal
proposed terms of a merger of equals to MindSpring and Donaldson, Lufkin &
Jenrette.

                                       36
<PAGE>
    On August 18, 1999, Mr. Betty, Mr. Dayton and Mr. Brewer discussed by
telephone the preliminary term sheet and related merger matters. During that
conference call, Mr. Brewer indicated that he and the MindSpring board of
directors needed additional time to analyze the proposed terms and consider the
overall concept of a business combination between EarthLink and MindSpring.
Mr. Brewer also suspended any further merger discussions between EarthLink and
MindSpring in order to permit MindSpring to adequately consider alternative
transactions, and told Mr. Betty that he would contact him on August 24, 1999.
On August 24, 1999, Mr. Brewer and Mr. Betty held a telephonic meeting during
which Mr. Brewer terminated the merger discussions between EarthLink and
MindSpring.

    On August 26, 1999, at Mr. Betty's request, Mr. Betty and Campbell B. Lanier
III, one of the MindSpring directors, met in West Point, Georgia to resume
discussions. Mr. Betty made a presentation regarding a potential merger of
equals between EarthLink and MindSpring. No agreement on any specific terms
regarding a business combination was reached during that meeting.

    On September 8, 1999, Mr. Betty, Mr. Brewer, Mr. Lanier and Mr. McQuary held
a meeting in Atlanta to begin preliminary substantive discussions of a merger of
equals between EarthLink and MindSpring. The attendees discussed various terms
of a merger, including overall structure, share exchange values, composition of
the board of directors and executive management, location of headquarters, name
of the post-merger company and overall company strategy and company
philosophies. On September 9, 1999, Mr. McQuary and Mr. Betty had a telephone
conversation to further discuss these matters. The representatives of EarthLink
and MindSpring reached preliminary agreement on some of the basic terms of the
proposed reorganization, including transaction structure, share exchange terms
and the name of the combined company, and authorized their respective investment
banking firms and law firms to prepare and negotiate a term sheet for a
reorganization of the companies.

    Throughout September 1999, Mr. Betty and EarthLink's legal counsel,
Hunton & Williams, engaged in discussions with Sprint Corporation and its legal
counsel regarding interpretation of the various agreements and documents entered
into by EarthLink, Sprint and Sprint's affiliates in connection with the 1998
strategic alliance between EarthLink and Sprint. In those discussions, EarthLink
and Sprint confirmed that they were in agreement about the impact under the
applicable documents of an EarthLink--MindSpring merger on the strategic
alliance. Under the governance agreement between EarthLink and Sprint, Sprint's
approval of the proposed reorganization was required. At a meeting of the
EarthLink board of directors, both of the Sprint designees to EarthLink's board
of directors gave special approval to the proposed reorganization.

    Also throughout September, EarthLink's independent accountants,
PricewaterhouseCoopers LLP and MindSpring's independent auditors, Arthur
Andersen LLP, engaged in analysis and discussions with members of the
accounting, financial and legal staffs of both EarthLink and MindSpring
regarding whether the proposed reorganization could qualify as a
pooling-of-interests for accounting purposes.

    On September 10, 1999, EarthLink delivered a term sheet to MindSpring.
Following their analysis of the terms and provisions of the proposed
reorganization as set forth in the term sheet, representatives of MindSpring,
Donaldson, Lufkin & Jenrette and MindSpring's legal counsel, Hogan & Hartson
L.L.P., entered into substantive negotiations and discussions with EarthLink and
its counsel and Credit Suisse First Boston, which included discussions regarding
board representation, management structure, termination fees and options, among
other things. At the conclusion of these negotiations the term sheet was
finalized.

    From September 10, 1999 through September 22, 1999, definitive documents
implementing the reorganization were drafted, discussed and negotiated by the
various parties, including members of the executive management of EarthLink and
MindSpring as well as their respective legal, investment banking and accounting
advisors. During that period, many meetings and conferences took place in

                                       37
<PAGE>
Pasadena and Atlanta and via telephone for negotiation of the reorganization
agreement, legal and accounting issues, due diligence and other related
purposes.

    On September 14, 1999, Mr. Lanier and William H. Scott, III, two of
MindSpring's directors, met in Kansas City, Missouri with several members of
Sprint's board of directors to discuss the proposed reorganization.

    On September 17 and 21, 1999, the EarthLink board of directors met to
discuss the proposed reorganization, including without limitation the share
exchange terms, key terms of the reorganization agreement and structure of the
reorganization and the post-reorganization entity. At the September 21, 1999
meeting, Credit Suisse First Boston made a presentation to the EarthLink board
of directors as to the fairness of the transaction and the share exchange ratios
from a financial point of view. After reviewing all the various factors in its
assessment of the proposed reorganization, Credit Suisse First Boston indicated
that in its opinion, the proposed share exchange ratios and the reorganization
would be fair from a financial point of view.

    On September 16 and 21, 1999, the MindSpring board of directors met to
discuss the proposed reorganization, including without limitation the share
exchange terms, key terms of the reorganization agreement and structure of the
reorganization and the post-reorganization entity.

    On September 22, 1999, the EarthLink board of directors met to deliberate
and make a final decision on whether to approve or reject the proposed
reorganization with MindSpring. After full consideration and discussion of the
structure, terms and conditions of the proposed reorganization with MindSpring,
the EarthLink board of directors unanimously approved the proposed transaction
as in the best interests of its stockholders.

    Also on September 22, 1999, the MindSpring board of directors met to
deliberate and make a final decision on whether to approve or reject the
proposed reorganization with EarthLink. At the September 22, 1999 meeting,
Donaldson, Lufkin and Jenrette made a financial presentation to the MindSpring
board of directors and Donaldson, Lufkin & Jenrette delivered its opinion to the
board of directors of MindSpring that the ratio for the exchange of shares of
MindSpring common stock in the reorganization was fair, from a financial point
of view, to the stockholders of MindSpring. After full consideration and
discussion of the structure, terms and conditions of the proposed reorganization
with EarthLink, the MindSpring board of directors unanimously approved the
proposed transaction as in the best interests of its stockholders.

    On September 22, 1999, EarthLink, MindSpring and WWW Holdings finalized and
executed the reorganization agreement and all related agreements and documents.
On September 23, 1999, the parties announced the proposed consolidation of
EarthLink and MindSpring by a joint press release sent to the major business
wire and media agencies.

REASONS OF EARTHLINK FOR AGREEING TO THE REORGANIZATION WITH MINDSPRING

    At a meeting held on September 22, 1999, the board of directors of EarthLink
voted unanimously to approve the transactions contemplated by the reorganization
agreement, determined that such transactions were fair to, in the best interests
of, and advisable for the stockholders of EarthLink, and resolved to recommend
that the stockholders adopt the reorganization agreement. In arriving at its
decision to approve the reorganization agreement and to recommend its adoption
to the EarthLink stockholders, the board gave careful consideration to the
following factors, among others:

    - the board's thorough evaluation of a variety of potential strategic
      alternatives and its analysis of the viability of and risks associated
      with each alternative;

    - the aggregation of EarthLink's member base with the member base of

      the EarthLink series A preferred stock exchange ratio was fair from a
      financial point of view to the holders of the EarthLink series A preferred
      stock, and the EarthLink series B preferred stock exchange ratio was fair
      from a financial point of view to the holders of the EarthLink series B
      preferred stock. THE OPINION OF CREDIT SUISSE FIRST BOSTON CONTAINS A
      DESCRIPTION OF THE

                                       39
<PAGE>
      FACTORS CONSIDERED, THE ASSUMPTIONS MADE AND THE SCOPE OF REVIEW
      UNDERTAKEN BY CREDIT SUISSE FIRST BOSTON IN RENDERING ITS OPINION. A MORE
      DETAILED DESCRIPTION OF CREDIT SUISSE FIRST BOSTON'S FAIRNESS OPINION IS
      PROVIDED BELOW UNDER THE CAPTION "OPINION OF EARTHLINK FINANCIAL ADVISOR"
      AND THE FULL TEXT OF THE FAIRNESS OPINION RECEIVED BY THE BOARD OF
      DIRECTORS FROM CREDIT SUISSE FIRST BOSTON IS INCLUDED AS ANNEX B ATTACHED
      TO THIS JOINT PROXY STATEMENT/PROSPECTUS.

    The EarthLink board also considered potentially negative factors in its
deliberations concerning the reorganization, including:

    - the potential disruption of EarthLink's business that might result from
      the announcement of the reorganization;

    - the risk that some key employees of EarthLink would depart;

    - the risk that anticipated benefits of the reorganization for EarthLink
      stockholders may not be realized as a result of possible changes in the
      Internet services industry in general or potential difficulties in
      integrating the businesses of EarthLink and MindSpring;

    - the significant cost involved in consummating the reorganization, the
      substantial management time and effort required to effect the
      reorganization and integrate the businesses of EarthLink and MindSpring
      and the related disruption to EarthLink's operations; and

    - the possible difficulties of integrating the operations, management and
      corporate cultures of MindSpring and EarthLink; and

    - the risk that the reorganization would not be consummated and that, under
      some circumstances, EarthLink could be required to pay a termination fee
      to MindSpring.

    The EarthLink board did not believe that the negative factors were
sufficient, individually or in the aggregate, to outweigh the potential
advantages of the reorganization.

    In light of all of the factors set forth above, the EarthLink board of
directors unanimously approved the transactions contemplated by the
reorganization agreement and, in order to induce MindSpring to enter into the
reorganization agreement, unanimously approved the grant of an option to
MindSpring to purchase up to 19.9% of EarthLink's outstanding common stock. In
view of the variety of factors considered in connection with its evaluation of
these transactions, the board of directors did not assign relative weights to
specific factors considered in reaching its decision, although the overall
strategic value of the transactions, as reflected above, were of paramount
importance to the board's decision. In evaluating the merger of EarthLink into
WWW Holdings and the other transactions contemplated by the reorganization
agreement, the board concluded that EarthLink's prospects for growth would be
substantially improved by entering into the reorganization agreement with
MindSpring, while, at the same time, significantly reducing the attendant
operational risks.

RECOMMENDATION OF THE EARTHLINK BOARD OF DIRECTORS

    THE EARTHLINK BOARD BELIEVES THAT THE TERMS OF THE REORGANIZATION AGREEMENT
ARE ADVISABLE AND IN THE BEST INTERESTS OF EARTHLINK AND ITS STOCKHOLDERS. THE
EARTHLINK BOARD HAS UNANIMOUSLY APPROVED THE REORGANIZATION AGREEMENT, AND
UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF EARTHLINK VOTE FOR THE ADOPTION
OF THE REORGANIZATION AGREEMENT.

OPINION OF EARTHLINK FINANCIAL ADVISOR

    EarthLink retained Credit Suisse First Boston to act as its exclusive
financial advisor in connection with the reorganization. Credit Suisse First
Boston was selected by the EarthLink board of directors to act as EarthLink's
financial advisor based on Credit Suisse First Boston's qualifications,
expertise and reputation, as well as Credit Suisse First Boston's investment
banking relationship and familiarity with EarthLink. On September 22, 1999, the
EarthLink board of directors met to review the proposed reorganization with
MindSpring and the final terms of the reorganization agreement. During this
meeting Credit Suisse First Boston rendered its oral opinion, subsequently
confirmed in writing on September 22, 1999, that, as of that date, based upon
and subject to the various considerations set forth in the Credit Suisse First
Boston opinion: the EarthLink common stock exchange ratio of 1.615 shares of WWW
Holdings common stock for each share of EarthLink common stock was fair from a
financial point of view to EarthLink's common stockholders, other than
MindSpring and its affiliates; the EarthLink series A exchange ratio of 1.615
shares of WWW Holdings series A convertible preferred stock for each share of
EarthLink series A convertible preferred stock was fair from a financial point
of view to EarthLink's series A preferred stockholders; and the EarthLink
series B exchange ratio of 1.615 shares of WWW Holdings series B convertible
preferred stock in exchange for each share of EarthLink series B convertible
preferred stock was fair from a financial point of view to EarthLink's series B
preferred stockholders.

    A summary of the material terms of the Credit Suisse First Boston opinion is
set forth below. The full text of the opinion is attached as ANNEX B to this
joint proxy statement/prospectus and is incorporated by reference into this
joint proxy statement/prospectus. Credit Suisse First Boston has consented to
the use of its fairness opinion in connection with this joint proxy
statement/prospectus. EarthLink stockholders are urged to, and should, read the
Credit Suisse First Boston opinion carefully. The full text of the Credit Suisse
First Boston opinion sets forth, among other things, assumptions made,
procedures followed, matters considered and limitations on the scope of the
review undertaken by Credit Suisse First Boston in rendering its opinion. The
Credit Suisse First Boston opinion addresses only the fairness from a financial
point of view of: the EarthLink common stock exchange ratio of 1.615 shares of
WWW Holdings common stock for each share of EarthLink common stock to
EarthLink's common stockholders, other than MindSpring and its affiliates; the
EarthLink series A exchange ratio of 1.615 shares of WWW Holdings series A
convertible preferred stock for each share of EarthLink series A convertible
preferred stock to EarthLink's series A preferred stockholders; and the
EarthLink series B exchange ratio of 1.615 shares of WWW Holdings series B
convertible preferred stock to each share of EarthLink's series B convertible
preferred stock to EarthLink's series B preferred stockholders, as of the date
of the Credit Suisse First Boston opinion, and does not constitute a
recommendation to any EarthLink stockholder as to how that stockholder should
vote at the EarthLink special meeting. Credit Suisse First Boston was not
requested to, and did not, make any recommendation as to the value of the
reorganization exchange ratio, which matters were determined through
negotiations between MindSpring and EarthLink. The Credit Suisse First Boston
opinion was rendered on September 22, 1999. As such, it does not take into
account the effects of EarthLink's strategic alliance with Apple. Please refer
to the section titled "Information about EarthLink--Business--Recent
Development--Strategic Alliance with Apple Computer, Inc."

    In connection with its opinion, Credit Suisse First Boston, among other
things:

    - reviewed publicly available business and financial information relating to
      EarthLink and MindSpring, as well as the reorganization agreement;

    - reviewed other information, including financial forecasts, provided to it
      by EarthLink and MindSpring, and met with the management of both EarthLink
      and MindSpring to discuss the business and prospects of EarthLink and
      MindSpring;

                                       41
<PAGE>
    - relied upon the views of EarthLink's and MindSpring's management
      concerning the business, operational and strategic benefits and
      implications of the reorganization, including financial information
      provided to Credit Suisse First Boston by EarthLink and MindSpring
      relating to the synergistic values and operating cost savings expected to
      be achieved through the combination of the operations of EarthLink and
      MindSpring;

    - considered certain financial and stock market data of EarthLink and
      MindSpring, and compared that data with similar data for other publicly
      held companies in businesses it deemed similar to those of EarthLink and
      MindSpring;

    - considered the financial terms, to the extent publicly available, of
      certain other business combinations and other transactions that have
      recently been effected; and

    - considered other information, financial studies, analyses and
      investigations and financial, economic and market criteria as it deemed
      relevant.

    In connection with its review, Credit Suisse First Boston did not assume any
responsibility for independent verification of any of the information described
above and relied on its being complete and accurate in all material respects.
Credit Suisse First Boston assumed that any estimates or information used in its
analysis had been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the management of each of EarthLink and
MindSpring as to the future financial performance of EarthLink and MindSpring,
as the case may be, and, upon consummation of the reorganization, WWW Holdings.
In addition, Credit Suisse First Boston did not make an independent evaluation
or appraisal of the assets or liabilities, contingent or otherwise, of EarthLink
or MindSpring, nor was Credit Suisse First Boston furnished with any evaluations
or appraisals of these assets or liabilities. The Credit Suisse First Boston
opinion is necessarily based upon financial, economic, market and other
conditions as they existed and could be evaluated on the date of the Credit
Suisse First Boston opinion.

    Credit Suisse First Boston did not express any opinion as to what the value
of the WWW Holdings common stock, WWW Holdings series A convertible preferred
stock or WWW Holdings series B convertible preferred stock actually will be when
issued to EarthLink's stockholders pursuant to the merger of EarthLink into WWW
Holdings or the prices at which the WWW Holdings common stock, WWW Holdings A
convertible preferred stock or WWW Holdings series B convertible preferred stock
will trade subsequent to the reorganization. With the consent of the EarthLink
board of directors, Credit Suisse First Boston did not consider, and its opinion
does not in any manner address, the impact of the reorganization on any
governance rights or other rights or interests that holders of the EarthLink
series A convertible referred stock or series B convertible preferred stock may
have with respect to EarthLink under the terms of the securities or under
agreements with EarthLink and/or any third parties.

    In preparing the Credit Suisse First Boston opinion, Credit Suisse First
Boston performed a variety of financial and comparative analyses. The
preparation of a fairness opinion is a complex process and is not necessarily
susceptible to partial analysis or summary description. Credit Suisse First
Boston believes that its analyses must be considered as a whole and that
selecting portions of its analyses and of the factors considered by it, without
considering all analyses and factors, could create a misleading view of the
processes underlying the Credit Suisse First Boston opinion. No company or
transaction used in the analysis performed by Credit Suisse First Boston as a
comparison is identical to EarthLink, MindSpring or the contemplated
reorganization. In addition, Credit Suisse First Boston may have given various
analyses more or less weight than other analyses, and may have deemed various
assumptions more or less probable than other assumptions, so that the range of
valuation resulting from any particular analysis described below should not be
taken to be Credit Suisse First Boston's view of the actual value of EarthLink,
MindSpring or WWW Holdings. In performing its analyses, Credit Suisse First
Boston made numerous assumptions with respect to industry performance, general
business and

                                       42
<PAGE>
economic conditions and other matters, many of which are beyond the control of
EarthLink or MindSpring. The analyses performed by Credit Suisse First Boston
are not necessarily indicative of actual values or actual future results, which
may be significantly more or less favorable than suggested by the analyses. In
addition, analyses relating to the value of businesses or assets do not purport
to be appraisals or to necessarily reflect the prices at which businesses or
assets may actually be sold. The analyses performed were prepared solely as part
of Credit Suisse First Boston's analysis of the fairness of the EarthLink common
stock exchange ratio from a financial point of view to EarthLink's common
stockholders, other than MindSpring and its affiliates, the EarthLink series A
exchange ratio from a financial point of view to EarthLink's series A preferred
stockholders and the EarthLink series B exchange ratio from a financial point of
view to EarthLink's series B preferred stockholders, and were provided to the
EarthLink board of directors in connection with the delivery of the Credit
Suisse First Boston opinion.

    The following is a summary of the material financial analyses performed by
Credit Suisse First Boston in connection with the preparation of its opinion,
and reviewed with the EarthLink board of directors at a meeting of the EarthLink
board held on September 21, 1999. Certain of the summaries of those financial
analyses include information presented in tabular format. In order to understand
fully the material financial analyses used by Credit Suisse First Boston, the
tables should be read together with the text of each summary. The tables alone
do not constitute a complete description of the material financial analyses.

    HISTORICAL STOCK PRICE ANALYSIS.  Credit Suisse First Boston analyzed the
prices at which the EarthLink common stock traded since EarthLink's initial
public offering on January 22, 1997, through September 17, 1999. Credit Suisse
First Boston noted that the all-time high price for EarthLink common stock was
$90.50 on April 13, 1999, and the all-time low price for EarthLink common stock
was $4.31 on May 1, 1997.

    Credit Suisse First Boston also analyzed the prices at which the MindSpring
common stock traded since MindSpring's initial public offering on March 14,
1996, through September 17, 1999. Credit Suisse First Boston noted that the
all-time high price for MindSpring common stock was $62.47 on April 26, 1999,
and the all-time low price for MindSpring common stock was $0.93 on December 4,
1996.

    EXCHANGE RATIO ANALYSIS.  Credit Suisse First Boston reviewed the average of
the ratio of the closing price of EarthLink common stock divided by the closing
price of MindSpring common stock over various periods ending September 17, 1999,
and computed the premium (discount) represented by the EarthLink common stock
exchange ratio and the ratio of the closing price of EarthLink common stock over
the closing price of the MindSpring common stock as of September 17, 1999,
referred to as the current market exchange ratio over the average exchange
ratios. The following table sets forth the average exchange ratios over the
various periods covered and the premium (discount) represented by the current
market exchange ratio and the EarthLink common stock exchange ratio over the
average exchange ratio:

                                       43

    Credit Suisse First Boston noted that the EarthLink common stock exchange
ratio of 1.615 shares of WWW Holdings common stock for each share of EarthLink
common stock represented a premium over the Average Exchange Ratios for all
periods considered and the Current Market Exchange Ratio represented a premium
over the Average Exchange Ratios for all periods considered, except for the 10
and 30 trading day periods ending on September 17, 1999.

    Credit Suisse First Boston noted that the EarthLink common stock exchange
ratio of 1.615 shares of WWW Holdings common stock for each share of EarthLink
common stock implied a nominal transaction value of $43.81 per share of
EarthLink common stock based on the closing stock price as of September 17,
1999. Credit Suisse First Boston also noted that the implied transaction value
of $43.81 per share of EarthLink common stock as of September 17, 1999 was above
the average of the closing stock prices for EarthLink for the periods ending
one day and 10 days prior to September 17, 1999 and was below the averages for
the other periods.

    PRECEDENT MERGER-OF-EQUALS TRANSACTIONS ANALYSIS.  Credit Suisse First
Boston reviewed 56 merger-of-equal transactions across a wide range of
industries and compared certain publicly available statistics for the selected
merger-of-equals transactions to the comparable financial statistics for
EarthLink and MindSpring based on the value of MindSpring implied by the
MindSpring common stock exchange ratio and the closing prices of the EarthLink
common stock and MindSpring common stock as of September 17, 1999.

    The following table presents the median and mean exchange ratio premium both
one trading day and 30 trading days prior to the announcement of the
transaction:

MindSpring..................................................       (8.4)%            (10.7)%
</TABLE>

    Credit Suisse First Boston noted that the MindSpring common stock exchange
ratio of 1.00 share of WWW Holdings common stock for each share of MindSpring
common stock represented a discount to the ratio of the closing price of
MindSpring common stock multiplied by the EarthLink common stock exchange ratio
and divided by the closing price of EarthLink common stock, measured on both one
trading day and 30 trading days prior to the announcement of the transaction by
way of comparison, Credit Suisse First Boston noted that in the selected
merger-of-equals transactions, the median and mean of the corresponding ratios
resulted in a premium to the ratio of the stock prices of the respective
companies both one trading day and 30 trading days prior to the announcement of
the respective transaction.

    No transaction utilized as a comparison in the precedent merger-of-equals
transactions analysis is identical to the reorganization. In evaluating the
merger-of-equals transaction, Credit Suisse First Boston 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 EarthLink and MindSpring, such as the impact of competition on the
businesses of EarthLink and MindSpring and the industry generally, industry
growth and the absence of any adverse material change in the financial condition
and prospects of EarthLink, MindSpring or the industry or in the financial
markets in general. Mathematical analysis, such as determining the average or
median, is not in itself a meaningful method of using comparable transaction
data.

    CONTRIBUTION ANALYSIS.  Credit Suisse First Boston analyzed the relative
contributions of MindSpring and EarthLink to various operational and financial
metrics for various periods in calendar

                                       44
<PAGE>
years 1999, 2000 and 2001, based on estimates prepared by securities research
analysts with respect to MindSpring, EarthLink's management with respect to
EarthLink, and EarthLink's and MindSpring's managements with respect to WWW
Holdings. In particular, Credit Suisse First Boston compared the contribution of
EarthLink to the projected number of members of WWW Holdings at the end of
calendar years 2000 and 2001 and to net income before sales and marketing
expenses in calendar year 2001 to the pro forma primary and fully-diluted
ownership of WWW Holdings by EarthLink's stockholders of 51.0% and 51.9%,
respectively, implied by the reorganization. The following table sets forth the
results of Credit Suisse First Boston's analysis:

<TABLE>
<CAPTION>
                                                              EARTHLINK CONTRIBUTION
                                                              ----------------------
<S>                                                           <C>
Members as of December 31, 2000.............................      59.9%--61.1%
Members as of December 31, 2001.............................      47.4%--48.9%
Net Income Before Sales and Marketing Expenses for Calendar
  year 2001.................................................      40.8%--48.3%
</TABLE>

    Credit Suisse First Boston noted that the pro forma primary and
fully-diluted ownership of WWW Holdings by EarthLink's stockholders was less
than EarthLink's contribution of members to WWW Holdings as of December 31,
2000, but exceeded EarthLink's contribution of members to WWW Holdings as of
December 31, 2001 and of net income before sales and marketing expense for
calendar year 2001.

    PRO FORMA EARNINGS IMPACT ANALYSIS.  Credit Suisse First Boston analyzed
certain pro forma effects of the mergers of EarthLink and MindSpring into WWW
Holdings, including, among other things, the impact of the mergers on the
estimated earnings per share as reported and earnings per share before sales and
marketing expenses for calendar years 2000 and 2001 based on estimates prepared
by securities research analysts with respect to MindSpring, EarthLink's
management with respect to EarthLink and EarthLink's and MindSpring's
managements with respect to WWW Holdings. The following table sets forth the
resulting accretion/(dilution) to WWW Holdings' earnings per share as reported
and earnings per share before sales and marketing expenses for the calendar
years 2000 and 2001 based on such estimates:

    ILLUSTRATIVE FUTURE TRADING ANALYSIS.  Credit Suisse First Boston computed
the equivalent per share value of EarthLink common stock both on a stand-alone
basis and assuming the reorganization is completed. This analysis was based upon
the projected number of members at the end of calendar years 1999, 2000 and 2001
prepared by securities research analysts with respect to MindSpring, EarthLink's
management with respect to EarthLink and EarthLink's and MindSpring's management
with respect to WWW Holdings. The analysis was also based on a range of value
per member of $1,000 to $5,000. Based on the stand-alone estimates for
EarthLink, Credit Suisse First Boston noted the following equivalent values per
share of EarthLink common stock:

</TABLE>

    Credit Suisse First Boston analyzed the equivalent per share value of
EarthLink common stock based upon calendar year 2000 revenues based on estimates
prepared by securities research analysts with respect to MindSpring, EarthLink's
management with respect to EarthLink and EarthLink's and MindSpring's
managements with respect to WWW Holdings and on multiples ranging from 2.5 times
to 7.0 times one-year forward revenues. Based on the stand-alone estimates, this
analysis resulted in a stand-alone equivalent value per share of EarthLink
common stock one year from the date of this analysis ranging from $61.73 to
$159.76. Based on the pro forma calendar year 2000 revenues for WWW Holdings
taking into account synergies and cost savings expected to be achieved through
the reorganization, the analysis resulted in an equivalent value per share of
EarthLink common stock one year from the date of this analysis ranging from
$58.81 to $161.28.

    Credit Suisse First Boston also analyzed, on a stand-alone basis and
assuming the reorganization is completed, the earnings per share and equivalent
values per share of EarthLink common stock based on estimates prepared by
securities research analysts with respect to MindSpring, EarthLink's management
with respect to EarthLink and EarthLink's and MindSpring's managements with
respect to WWW Holdings. The following table sets forth Credit Suisse First
Boston's analysis, using a range of one-year forward earnings per share
multiples and a range of operating margins indicated in the table:

</TABLE>

    Credit Suisse First Boston noted that the ranges of equivalent values per
share of EarthLink common stock derived from the illustrative future trading
analysis generally overlapped.

    As described above, Credit Suisse First Boston's opinion and presentation to
the EarthLink board of directors was one of many factors taken into
consideration by the EarthLink board of directors in making its determination to
recommend the reorganization agreement and the transactions contemplated by the
reorganization agreement. Consequently, the analyses described above should not
be viewed as determinative of the opinion of the EarthLink board of directors or
the management of EarthLink with respect to the value of EarthLink or MindSpring
or whether the EarthLink board of directors would have been willing to agree to
a different exchange ratio.

    The EarthLink board of directors retained Credit Suisse First Boston to act
as its financial advisor in connection with the reorganization. Credit Suisse
First Boston was selected by the EarthLink board of directors based on Credit
Suisse First Boston's qualifications, expertise and reputation, as well as its
familiarity with EarthLink. Credit Suisse First Boston is an internationally
recognized investment banking and advisory firm. Credit Suisse First Boston, as
part of its investment banking business, is continuously engaged in the
valuation of businesses and securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. Credit Suisse First Boston acted as
lead underwriter in connection with EarthLink's January 13, 1999 follow-on
offering of common stock and received approximately $3.3 million from EarthLink
in connection with

                                       46
<PAGE>
its role as lead underwriter. In the ordinary course of its business, Credit
Suisse First Boston and its affiliates may actively trade the debt and equity
securities of EarthLink and MindSpring for its own account and for the accounts
of its customers and, accordingly, may at any time hold a long or short position
in those securities.


    Pursuant to an engagement letter dated June 10, 1999 and amended on
September 15, 1999, EarthLink engaged Credit Suisse First Boston to provide
financial advisory services to the EarthLink board of directors in connection
with the reorganization, including, among other things, rendering its opinion
and making the presentation referred to above. Pursuant to the terms of the
engagement letter, EarthLink has agreed to pay Credit Suisse First Boston a fee
based on the enterprise value of EarthLink, which fee, based upon the closing
sale price for EarthLink common stock on January 3, 2000, of $44.75 per share,
would equal approximately $10.4 million. In addition, EarthLink has agreed to
reimburse Credit Suisse First Boston for its out-of-pocket expenses, including
attorney's fees, incurred in connection with its engagement and to indemnify
Credit Suisse First Boston and certain related persons against various
liabilities and expenses arising out of or in conjunction with its rendering of
services under its engagement, including liabilities arising under the federal
securities laws.


REASONS OF MINDSPRING FOR AGREEING TO THE REORGANIZATION WITH EARTHLINK

    The Internet access market currently is characterized by one dominant
provider, America Online Inc., or AOL, and numerous other providers of Internet
access ranging from national commercial Internet service providers and
telecommunications companies to regional and local Internet service providers.
The MindSpring board believes that significant advantages will accrue to the
first company that can distinguish itself from the pack and establish itself as
the clear alternative to AOL in the Internet access market. By combining their
businesses, MindSpring and EarthLink will create the nation's second largest
provider of Internet access after AOL, and establish the combined company as a
national brand alternative to AOL. In addition, the combined company will be
able to share resources and capitalize on synergies that will increase its
ability to attract and retain members and compete effectively at the top tier of
the industry. The MindSpring board believes that the reorganization will enable
the combined company to achieve these goals and enhance its strategic and market
position more quickly than MindSpring could have achieved on its own.

    In addition, the combined company is expected to realize several benefits
from the increased size of its operations. The MindSpring board believes that
the increased scale of operations will enable the combined company to, among
other things:

    - strengthen its negotiating position with vendors, network providers and
      content providers;

    - become a leading Internet service provider portal site on the Internet;
      and

    - provide greater opportunities to develop alternative revenue streams.

The MindSpring board further believes that the combined size of MindSpring and
EarthLink will likely provide additional business and marketing opportunities to
the combined company that might not otherwise be available to the two companies
on an individual basis.

    The MindSpring board also believes that the reorganization will result in
significant opportunities for cost savings, revenue growth, technological
development and other benefits. The combined company is expected to achieve
significant revenue, expense and capital synergies through economies of scale,
the elimination of duplicative expenditures and the consistent use of the best
practices of MindSpring and EarthLink. The MindSpring board expects the combined
company to obtain brand efficiency in sales and marketing by utilizing the
combined resources of the two companies to promote one national brand instead of
two. The combined company will also be able to take advantage of the
complementary blend of assets and capabilities contributed by MindSpring and
EarthLink to improve and expand its service offerings and accelerate its member
growth rate.

                                       47
<PAGE>
    In reaching its decision to approve, declare advisable and recommend
adoption of the reorganization agreement and the transactions contemplated by
the reorganization agreement, the MindSpring board also considered a number of
additional factors, including those described below:

    - the strategic alternatives available to MindSpring, including potential
      business combinations with other entities, the strong strategic fit
      between MindSpring and EarthLink and the potential for significant near
      term and long term synergies expected to result from the reorganization;

    - information concerning the business, assets, liabilities, capital
      structure, financial performance and condition and prospects of MindSpring
      and EarthLink;

    - historical and forecasted financial information relating to MindSpring and
      EarthLink, the results of MindSpring's due diligence investigation of
      EarthLink and the other information exchanges with EarthLink;

    - the views of MindSpring's management regarding the proposed reorganization
      and the anticipated economic and operational benefits to be achieved
      through the application of economies of scale and the anticipated
      synergies resulting from the proposed reorganization;

    - the consistency of the strategies that the two companies were pursuing;

    - the impact of the reorganization on the combined company's ability to
      maintain and enhance its reputation for delivering high quality services
      to customers;

    - the impact that the reorganization would be expected to have on the
      combined company's balance sheet, earnings and cash flow;

    - the merger exchange ratio and the current and historical market prices for
      MindSpring and EarthLink common stock;

    - the financial presentation and opinion of Donaldson, Lufkin and Jenrette
      Securities Corporation to the MindSpring board to the effect that, on the
      date of its opinion and based upon and subject to the various
      considerations set forth in its opinion, the ratio for the exchange of
      shares of MindSpring common stock for WWW Holdings common stock to be
      effected in the merger of MindSpring into WWW Holdings was fair, from a
      financial point of view, to the stockholders of MindSpring (see "Opinion
      of MindSpring Financial Advisor");

    - the composition and strength of the management of the combined company and
      the composition of the board of directors of the combined company;

    - the terms and structure of the transaction and the terms and conditions of
      the reorganization agreement, including the fixed nature of the ratio for
      the exchange of shares, the size of the termination fees and the
      circumstances in which they are payable;

    - the fact that the reorganization agreement would permit MindSpring to
      terminate the reorganization agreement, upon payment of a termination fee
      to EarthLink, if the MindSpring board withdraws its recommendation for
      adoption of the reorganization agreement to the stockholders pursuant to
      its terms;

    - the ability to consummate the mergers of MindSpring and EarthLink into WWW
      Holdings as a tax free reorganization for federal income tax purposes;

    - the ability to treat the reorganization for accounting purposes as a
      pooling of interests; and

    - the terms of the option agreements, which were reciprocal in nature and
      which the board of directors approved in order to induce EarthLink to
      enter into the reorganization agreement.

                                       48
<PAGE>
    The MindSpring board also considered a number of countervailing factors in
its deliberations concerning the reorganization, including:

    - the potential disruption of MindSpring's business that might result from
      the announcement of the reorganization;

    - the risk that some key employees of MindSpring would depart;

    - the possible difficulties of integrating the operations, management and
      corporate cultures of MindSpring and EarthLink; and

    - the risk that the reorganization would not be consummated.

    In the view of the MindSpring board of directors, these considerations were
not sufficient, individually or in the aggregate, to outweigh the advantages of
the reorganization.

    The foregoing discussion of the information and factors considered by the
MindSpring board of directors in approving the reorganization is not meant to be
exclusive, but includes the material factors considered by the MindSpring board
of directors in reaching its decision. In light of the wide variety of factors
considered in its evaluation of the reorganization and the complexity of these
matters, the MindSpring board of directors did not find it practicable to and
did not attempt to quantify, rank or otherwise assign relative weights to these
factors. The MindSpring board of directors conducted an overall analysis of the
factors described above, including discussion with MindSpring's management and
legal, financial and accounting advisors. In considering the factors described
above, individual members of the MindSpring board of directors may have given
different weight to different factors. The MindSpring board of directors
considered all these factors as a whole and considered the factors overall to be
favorable to, and to support, its determination.

    After considering all of the factors described above as of the date of this
joint proxy statement/ prospectus, the MindSpring board of directors continues
to believe that the reorganization is advisable and in the best interests of
MindSpring and its stockholders and continues to recommend that MindSpring
stockholders vote FOR adoption of the reorganization agreement.

RECOMMENDATION OF THE MINDSPRING BOARD OF DIRECTORS

    THE MINDSPRING BOARD BELIEVES THAT THE TERMS OF THE REORGANIZATION AGREEMENT
ARE ADVISABLE AND IN THE BEST INTERESTS OF MINDSPRING AND ITS STOCKHOLDERS, HAS
UNANIMOUSLY APPROVED THE REORGANIZATION AGREEMENT, THE OPTION AGREEMENTS AND THE
TRANSACTIONS CONTEMPLATED BY THE REORGANIZATION AGREEMENT, AND UNANIMOUSLY
RECOMMENDS THAT THE STOCKHOLDERS OF MINDSPRING VOTE FOR THE ADOPTION OF THE
REORGANIZATION AGREEMENT.

OPINION OF MINDSPRING FINANCIAL ADVISOR

    Donaldson, Lufkin & Jenrette Securities Corporation has acted as the
exclusive financial advisor to MindSpring in connection with the reorganization.
In its role as financial advisor to MindSpring, Donaldson, Lufkin & Jenrette was
asked by MindSpring to render an opinion to the board of directors of MindSpring
as to the fairness, from a financial point of view, of the exchange ratio of one
share of WWW Holdings common stock in exchange for each share of MindSpring
common stock to the holders of MindSpring common stock. On September 22, 1999,
at a meeting of the MindSpring board of directors held to evaluate the
reorganization, Donaldson, Lufkin & Jenrette delivered to the MindSpring board a
written opinion, dated September 22, 1999, to the effect that, as of the date of
the opinion and based on and subject to the assumptions, limitations and
qualifications stated in the opinion, the exchange ratio of one share of WWW
Holdings common stock in exchange for each share of MindSpring common stock was
fair, from a financial point of view, to the holders of the MindSpring common
stock.

    A COPY OF DONALDSON, LUFKIN & JENRETTE'S OPINION IS ATTACHED HERETO AS ANNEX
C AND SHOULD BE READ CAREFULLY FOR A DESCRIPTION OF THE PROCEDURES FOLLOWED,
ASSUMPTIONS MADE, OTHER MATTERS CONSIDERED AND LIMITATIONS OF THE REVIEW
UNDERTAKEN BY DONALDSON, LUFKIN & JENRETTE IN ARRIVING AT ITS OPINION.
DONALDSON, LUFKIN & JENRETTE'S OPINION WAS PREPARED FOR THE MINDSPRING BOARD AND
IS DIRECTED ONLY TO THE FAIRNESS OF THE EXCHANGE RATIO OF ONE SHARE OF WWW
HOLDINGS COMMON STOCK IN EXCHANGE FOR EACH SHARE OF MINDSPRING COMMON STOCK,
FROM A FINANCIAL POINT OF VIEW, TO THE HOLDERS OF MINDSPRING COMMON STOCK AND
DOES NOT CONSTITUTE A RECOMMENDATION TO ANY MINDSPRING STOCKHOLDER AS TO HOW
THAT STOCKHOLDER SHOULD VOTE ON THE ADOPTION OF THE REORGANIZATION AGREEMENT.
DONALDSON, LUFKIN & JENRETTE'S OPINION SPEAKS ONLY AS OF SEPTEMBER 22, 1999 AND,
ACCORDINGLY, DOES NOT TAKE INTO ACCOUNT THE EFFECTS OF EARTHLINK'S STRATEGIC
ALLIANCE WITH APPLE. SEE "INFORMATION ABOUT EARTHLINK--BUSINESS--RECENT
DEVELOPMENT--STRATEGIC ALLIANCE WITH APPLE COMPUTER, INC."

    The MindSpring board selected Donaldson, Lufkin & Jenrette to act as its
exclusive financial advisor in the reorganization because Donaldson, Lufkin &
Jenrette is an internationally recognized investment banking firm with
substantial expertise in the technology industry and in transactions similar to
the reorganization and because Donaldson, Lufkin & Jenrette is familiar with
MindSpring and its business. Donaldson, Lufkin & Jenrette, as part of its
investment banking services, is regularly engaged in the valuation of businesses
and securities in connection with mergers, acquisitions, underwritings, sales
and distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes.

    Donaldson, Lufkin & Jenrette was not requested to, and did not, make any
recommendation as to the value of the reorganization exchange ratio, which
matters were determined through arm's length negotiations between MindSpring and
EarthLink. Donaldson, Lufkin & Jenrette's opinion does not address the terms and
conditions of the reorganization agreement and the related documents, other than
the exchange ratio of one common share of WWW Holdings common stock in exchange
for each share of MindSpring common stock. In addition, Donaldson, Lufkin &
Jenrette's opinion does not address the relative merits of the reorganization
agreement or the other business strategies considered by the MindSpring board,
nor does it address the decision of MindSpring's board to approve the
reorganization. No restrictions or limitations were imposed by MindSpring upon
Donaldson, Lufkin & Jenrette with respect to the investigations made or
procedures followed by Donaldson, Lufkin & Jenrette in rendering its opinion.

    In arriving at its opinion, Donaldson, Lufkin & Jenrette:

    - reviewed drafts of the reorganization agreement and its exhibits;

    - reviewed financial and other information that was publicly available or
      furnished to it by MindSpring and EarthLink, including financial
      projections prepared by the managements of MindSpring and EarthLink and
      other information provided during discussions with MindSpring and
      EarthLink;

    - compared financial and securities data of MindSpring and EarthLink with
      various other companies whose securities are traded in public markets;

    - reviewed the historical stock prices of MindSpring common stock and
      EarthLink common stock; and

    - conducted other financial studies, analyses and investigations as
      Donaldson, Lufkin & Jenrette deemed appropriate for purposes of its
      opinion.

    In rendering its opinion, Donaldson, Lufkin & Jenrette relied on and assumed
the accuracy and completeness of all of the financial and other information that
was available to it from public sources, that was provided to it by MindSpring,
EarthLink or their respective representatives, or that it otherwise reviewed. In
particular, Donaldson, Lufkin & Jenrette relied on the estimates of the
management of MindSpring of the operating synergies achievable as a result of
the reorganization and

                                       50
<PAGE>
upon discussion of such synergies with the management of EarthLink. With respect
to the financial projections relating to MindSpring and EarthLink supplied to
Donaldson, Lufkin & Jenrette, Donaldson, Lufkin & Jenrette relied on
representations that they were reasonably prepared on the basis reflecting the
best currently available estimates and judgments of MindSpring and EarthLink as
to the future operating and financial performance of MindSpring, EarthLink and
the pro forma combined company. Donaldson, Lufkin & Jenrette did not assume any
responsibility for making any independent evaluation of any assets or
liabilities or for making any independent verification of any of the information
that it reviewed. Donaldson, Lufkin & Jenrette further assumed that the
reorganization would qualify for pooling of interests accounting treatment and
as a "tax-free" reorganization for federal income tax purposes. Donaldson,
Lufkin & Jenrette also relied as to certain legal matters on the advice of
counsel to MindSpring.

    Donaldson, Lufkin & Jenrette's opinion is necessarily based on economic
market, financial and other conditions as they existed on, and on the
information made available to it as of, the date of its opinion. It should be
understood that Donaldson, Lufkin & Jenrette's opinion speaks only as of
September 22, 1999 and, accordingly, does not take into account the effects of
EarthLink's strategic alliance with Apple. See "Information about
EarthLink--Business--Recent Development--Strategic Alliance with Apple Computer,
Inc." Donaldson, Lufkin & Jenrette expressed no opinion as to the prices at
which WWW Holdings common stock will actually trade at any time.

    The following is a summary of the material analyses that Donaldson,
Lufkin & Jenrette presented to the MindSpring board at its September 22, 1999,
meeting in connection with the preparation of its opinion. THE FINANCIAL
ANALYSES SUMMARIZED BELOW INCLUDE INFORMATION PRESENTED IN TABULAR FORMAT. IN
ORDER TO FULLY UNDERSTAND DONALDSON, LUFKIN & JENRETTE'S FINANCIAL ANALYSES, THE
TABLES MUST BE READ TOGETHER WITH THE TEXT OF EACH SUMMARY. THE TABLES ALONE DO
NOT CONSTITUTE A COMPLETE DESCRIPTION OF THE FINANCIAL ANALYSES. CONSIDERING THE
DATA IN THE TABLES BELOW WITHOUT CONSIDERING THE FULL NARRATIVE DESCRIPTION OF
THE FINANCIAL ANALYSES, INCLUDING THE METHODOLOGIES AND ASSUMPTIONS UNDERLYING
THE ANALYSIS, COULD CREATE A MISLEADING OR INCOMPLETE VIEW OF DONALDSON,
LUFKIN & JENRETTE'S FINANCIAL ANALYSES.

    SELECTED PUBLIC COMPANY ANALYSIS

    Donaldson, Lufkin & Jenrette compared financial and operating data of
MindSpring and EarthLink with the following selected Internet service providers:

    - America Online, Inc.;

    - Flashnet Communications, Inc.;

    - Prodigy Communications Corporation; and

    - Voyager.Net, Inc.

    Donaldson, Lufkin & Jenrette reviewed enterprise values, calculated as
market value of equity (as of September 20, 1999), plus debt and minority
interests, less cash and investments in unconsolidated affiliates, as multiples
of, among other things, 1999 and 2000 estimated revenues, 1999 and 2000
estimated earnings before interest, taxes, depreciation and amortization,
commonly known as "EBITDA," and members as of June 30, 1999. Donaldson,
Lufkin & Jenrette also reviewed equity values as multiples of 1999 and 2000
estimated net income before amortization expense.

    Estimated financial and operating data for the selected companies were based
on research analysts' estimates and estimated financial and operating data for
MindSpring and EarthLink were based on internal estimates of the managements of
MindSpring and EarthLink.

    As of September 20, 1999, MindSpring's enterprise value was 4.7x estimated
1999 revenue, 2.8x estimated 2000 revenue, 71.9x estimated 1999 EBITDA, 28.3x
estimated 2000 EBITDA, and $1,285.80 per member. MindSpring's equity value was
458.3x estimated 1999 net income before amortization

                                       51
<PAGE>
expense and 119.6x estimated 2000 net income before amortization expense.
EarthLink's enterprise value was 4.0x estimated 1999 revenue, 2.1x estimated
2000 revenue, 30.9x estimated 2000 EBITDA, and $1,031.10 per member. EarthLink's
equity value was 58.1x estimated 2000 net income before amortization expense.
EarthLink's trading multiples based on 1999 estimated EBITDA and net income
before amortization expense were not meaningful, because the underlying values
were negative numbers. The comparable group's (median) enterprise value was 6.0x
estimated 1999 revenue, 3.5x estimated 2000 revenue, and $1,256.10 per member.
The comparable group's (median) trading multiples on estimated 1999 and 2000
EBITDA and 1999 and 2000 net income before amortization expense were not
meaningful, because the underlying values were negative numbers. Donaldson,
Lufkin & Jenrette noted that the trading multiples referred to above, other than
those determined to be not meaningful, were generally in the range of the
relevant multiples for the comparable group.

    No company utilized in the "Selected Public Company Analysis" is identical
to MindSpring or EarthLink. Accordingly, an analysis of the above results
necessarily involves complex considerations and judgments concerning differences
in financial and operating characteristics of MindSpring and EarthLink and other
factors that could affect the public trading values of MindSpring and EarthLink
and the selected companies to which they are being compared. Mathematical
analysis is not in itself a meaningful method of using selected company data.

    HISTORICAL EXCHANGE RATIO ANALYSIS

    Donaldson, Lufkin & Jenrette analyzed historical average exchange ratios
between EarthLink and MindSpring. Donaldson, Lufkin & Jenrette reviewed the
1-month average, 3-month average, 6-month average, and 12-month average as of
September 20, 1999. The exchange ratio is calculated by dividing EarthLink's
stock price by MindSpring's stock price. The historical exchange ratios and
resulting implied EarthLink per share values and premiums paid per share are as
follows:

<TABLE>
<CAPTION>

</TABLE>

    Donaldson, Lufkin & Jenrette noted that the transaction exchange ratio fell
within the range of the average exchange ratios indicated at various intervals
during the last twelve months. Donaldson, Lufkin & Jenrette further noted that
the 1.615 transaction exchange ratio implied an EarthLink common share value of
$44.41 and an implied premium of 12.4% per EarthLink common share.

    DISCOUNTED CASH FLOW ANALYSIS

    Donaldson, Lufkin & Jenrette performed discounted cash flow analyses of
MindSpring and EarthLink, on a stand-alone basis, based on estimates of the
managements of MindSpring and EarthLink, respectively, in order to estimate the
net present value of the unlevered, after-tax cash flows that MindSpring and
EarthLink could generate for the remainder of 1999 through 2004. Applying
discount rates of 15.0% to 19.0% and multiples of terminal year 2004 EBITDA of
11.0x to 13.0x, this analysis produced an implied equity reference range for
MindSpring of approximately $28.00 to $38.00 per share and approximately $48.00
to $63.00 per share for EarthLink as compared to closing stock prices on
September 22, 1999 of $32.875 and $43.50 for MindSpring and EarthLink,
respectively. Based on the discounted cash flow analyses described above the
implied ownership percentage of the combined company for MindSpring would be
between 47.1% and 47.7% and the implied ownership percentage of EarthLink would
be between 52.3% and 52.9%. This compares to the actual ownership

                                       52
<PAGE>
split in the reorganization of approximately 50% for MindSpring stockholders and
approximately 50% for EarthLink stockholders, which actual split is higher for
the MindSpring stockholders than the range of implied ownership percentages
produced by this analysis.

    PRO FORMA DISCOUNTED CASH FLOW ANALYSIS

    Donaldson, Lufkin & Jenrette performed a discounted cash flow analysis of
WWW Holdings based on combined estimates of the managements of MindSpring and
EarthLink in order to estimate the net present value of the after-tax cash
flows, excluding interest or other payments attributable to indebtedness or
equity interests, that WWW Holdings could generate for the remainder of 1999
through 2004. Applying discount rates of 15.0% to 19.0% and multiples of
terminal year 2004 EBITDA of 11.0x to 13.0x, this analysis produced an implied
equity reference range for MindSpring stockholders of WWW Holdings of
approximately $35.00 to $47.00 per share. Donaldson, Lufkin & Jenrette noted
that MindSpring's closing stock price on September 22, 1999 was $32.875.

    PRO FORMA REORGANIZATION ANALYSIS

    Donaldson, Lufkin & Jenrette analyzed the potential pro forma effect of the
reorganization on the earnings per share before amortization expense from the
perspective of MindSpring stockholders using projections provided by the
managements of MindSpring and EarthLink. Assuming that the reorganization
qualifies for pooling of interests accounting treatment and the cost savings and
other potential synergies anticipated by the managements of MindSpring and
EarthLink to result from the reorganization are achieved, Donaldson, Lufkin &
Jenrette estimated that the reorganization would be accretive to earnings per
share before amortization expense for MindSpring stockholders in 2000 and 2001,
respectively. The actual results achieved by WWW Holdings may vary from
projected results, and the variations may be material.

    CONTRIBUTION ANALYSIS

    Donaldson, Lufkin & Jenrette analyzed the respective contributions of
MindSpring and EarthLink to the estimated 1999, 2000, and 2001 revenues, EBITDA,
EBITDA before sales and marketing expense and net income before amortization
charges of WWW Holdings based on internal estimates of the managements of
MindSpring and EarthLink. This analysis indicated the following relative
contributions of EarthLink and MindSpring:

    This compares to the actual ownership split in the reorganization of
approximately 50% for MindSpring stockholders and approximately 50% for
EarthLink stockholders. Donaldson, Lufkin & Jenrette noted that the analysis
yielded contribution percentages for each of MindSpring and EarthLink that,
depending on the measure and year considered, were above and below an
approximately 50% ownership split for each of MindSpring and EarthLink. In
particular, Donaldson, Lufkin & Jenrette noted that MindSpring's contribution
percentages were less than 50% for all measures except for EBITDA in 2000
(estimated) and EBITDA before sales and marketing expenses in 1999 (estimated).

    FAIRNESS OPINION PROCESS

    The above summary does not purport to be a complete description of
Donaldson, Lufkin & Jenrette's analyses but describes, in summary form, the
material analyses that Donaldson, Lufkin & Jenrette presented to the MindSpring
board on September 22, 1999, in connection with the preparation of its opinion.
The preparation of a fairness opinion involves various determinations as to the
most appropriate and relevant methods of financial analysis and the application
of those methods to the particular circumstances and, therefore, a fairness
opinion is not readily susceptible to partial or summary description. Each of
the analyses conducted by Donaldson, Lufkin & Jenrette was carried out in order
to provide a different perspective on the reorganization and add to the total
mix of information available. Donaldson, Lufkin & Jenrette did not form a
conclusion as to whether any individual analysis, considered in isolation,
supported or failed to support an opinion as to the fairness of the exchange
ratio of one share of WWW Holdings common stock in exchange for each share of
MindSpring common stock from a financial point of view. Rather, in reaching its
conclusion, Donaldson, Lufkin & Jenrette considered the results of the analyses
in light of each other and ultimately rendered its opinion based on the results
of all of the analyses taken as a whole. Donaldson, Lufkin & Jenrette did not
place particular reliance or weight on any individual analysis, but instead
concluded that its analyses, taken as a whole, supported its determination.
Accordingly, notwithstanding the separate factors summarized above, Donaldson,
Lufkin & Jenrette believes that its analyses must be considered as a whole and
that selecting portions of its analyses and the factors considered by it or
focusing on information presented in tabular format, without considering all
such factors and analyses or the narrative description of the analyses, could
create an incomplete or misleading view of the process underlying its opinion.
In addition, analyses relating to the value of businesses or securities do not
necessarily purport to be appraisals or to reflect the prices at which such
businesses or securities can actually be sold. The analyses performed by
Donaldson, Lufkin & Jenrette are not necessarily indicative of actual past or
future results or values, which may be significantly more or less favorable than
such estimates as those suggested by its analyses.

    ENGAGEMENT LETTER WITH DONALDSON, LUFKIN & JENRETTE

    Pursuant to an engagement letter dated June 21, 1999, MindSpring engaged
Donaldson, Lufkin & Jenrette to provide financial advisory services, which
included, among other things, rendering its opinion and making the presentation
referred to above. Pursuant to the terms of the engagement letter, MindSpring
has agreed to pay Donaldson, Lufkin & Jenrette a fee based on the enterprise
value of MindSpring, which fee, based upon the closing sales price for the
MindSpring common stock on January 3, 2000 of $28.00 per share, would equal
approximately $6.0 million. MindSpring has also agreed to reimburse Donaldson,
Lufkin & Jenrette for all out-of-pocket expenses, including the reasonable fees
and expenses of counsel, incurred by Donaldson, Lufkin & Jenrette in connection
with its engagement, and to indemnify Donaldson, Lufkin & Jenrette and related
persons against liabilities, including liabilities under the federal securities
laws, relating to or arising out of its services.

    Donaldson, Lufkin & Jenrette provides a full range of financial, advisory
and brokerage services and, in the ordinary course of business, Donaldson,
Lufkin & Jenrette and its affiliates may actively trade the debt and equity
securities of MindSpring and EarthLink for its own account and for the account
of customers and accordingly may at any time hold a long or short position in
such securities.

                                       54
<PAGE>
Donaldson, Lufkin & Jenrette has performed investment banking and other services
for MindSpring in the past and has received customary compensation for such
services. These services consisted of acting as lead manager of the MindSpring's
May 29, 1998 equity offering, co-manager of MindSpring's December 14, 1998
equity offering, and a co-manager of MindSpring's April 7, 1999 concurrent
equity and convertible debt offerings, in which Donaldson, Lufkin & Jenrette
earned fees from MindSpring of approximately $3.9 million in the aggregate.

NO DISSENTERS' RIGHTS

    EarthLink and MindSpring are Delaware corporations. Neither the EarthLink
nor the MindSpring stockholders have dissenters' rights of appraisal under
Delaware corporation law because their shares of common stock are traded on The
Nasdaq National Market and the stockholders will receive stock of the surviving
corporation that is listed on The Nasdaq National Market and cash instead of
fractional shares in exchange for their common stock as a result of the
reorganization. Regardless of the inapplicability of the statutory grant of
dissenters' rights of appraisal under Delaware corporation law, a Delaware
corporation may provide in its certificate of incorporation that dissenters'
rights will be available for the shares of any class or series of its stock as a
result of any merger or consolidation to which the corporation is a party.
Neither EarthLink nor MindSpring, however, have provided for dissenters' rights
of appraisal in their respective certificates of incorporation, and therefore,
their stockholders have no dissenters' rights of appraisal.

ACCOUNTING FOR THE REORGANIZATION UNDER THE POOLING OF INTERESTS METHOD

    EarthLink and MindSpring intend to account for their mergers into WWW
Holdings using the pooling of interests method of accounting.

    The mergers are conditioned on the receipt of favorable letters from the
independent public accountants of each of EarthLink and MindSpring to the effect
that each of the independent public accountants concurs with its client's
management's conclusions that no conditions exist with respect to its client
that would preclude WWW Holdings from accounting for the mergers of EarthLink
and MindSpring into WWW Holdings as a pooling of interests in conformity with
generally accepted accounting principles as described in Accounting Principles
Board Opinion No. 16 and the applicable rules and regulations of the Securities
and Exchange Commission.

RESTRICTIONS ON RESALES BY EARTHLINK AND MINDSPRING AFFILIATES

    All shares of WWW Holdings common stock that will be distributed to
stockholders of EarthLink and MindSpring in the reorganization will be freely
transferable, except for the restrictions on transfer imposed by the federal
securities laws on "affiliates" of EarthLink, MindSpring or WWW Holdings. Shares
of WWW Holdings common stock received by persons who are deemed to be affiliates
of EarthLink or MindSpring may be resold by them only in transactions permitted
by the resale provisions of Rule 145 or as otherwise permitted under the
Securities Act of 1933. Persons who may be deemed to be affiliates of EarthLink
or MindSpring generally include officers, directors and significant stockholders
of EarthLink and MindSpring. The reorganization agreement requires EarthLink and
MindSpring to use commercially reasonable efforts to cause each of their
affiliates to execute a written agreement to the effect that such persons will
not sell or dispose of any of the shares of WWW Holdings common stock issued to
them in the reorganization unless the sale or disposition has been registered
under the Securities Act of 1933, complies with Rule 145 or, in the opinion of
the affiliate's legal counsel, is otherwise exempt from the registration
requirements under the Securities Act of 1933.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

    The following discussion describes the material federal income tax
consequences of the reorganization to you as an EarthLink stockholder or a
MindSpring stockholder. This discussion is

                                       55
<PAGE>
based on current law, which is subject to change at any time, possibly with
retroactive effect. This discussion is not a complete description of all tax
consequences of the reorganization and, in particular, does not address all of
the federal income tax consequences applicable to stockholders who are subject
to special treatment under federal income tax law. In addition, this discussion
does not address the tax consequences of the reorganization under applicable
state, local or foreign laws. This discussion assumes you hold your shares of
EarthLink stock or MindSpring stock as a capital asset within the meaning of the
Internal Revenue Code. YOU SHOULD CONSULT WITH YOUR OWN TAX ADVISOR ABOUT THE
TAX CONSEQUENCES OF THE REORGANIZATION IN LIGHT OF YOUR PARTICULAR
CIRCUMSTANCES, INCLUDING THE APPLICATION OF ANY STATE, LOCAL OR FOREIGN LAW.

    EarthLink has received the opinion of Hunton & Williams, counsel to
EarthLink, that the merger of EarthLink into WWW Holdings will qualify as a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code. MindSpring has received the opinion of Hogan & Hartson L.L.P., counsel to
MindSpring, that the merger of MindSpring into WWW Holdings will qualify as a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code. Accordingly:

    - as an EarthLink stockholder or a MindSpring stockholder, you will not
      recognize gain or loss upon the exchange of your stock for WWW Holdings
      stock in the reorganization, except with respect to the receipt of cash
      instead of a fractional share;

    - none of EarthLink, MindSpring or WWW Holdings will recognize gain or loss
      upon completion of the merger of EarthLink or MindSpring into WWW
      Holdings;

    - the aggregate tax basis of the shares of WWW Holdings common stock or
      preferred stock you receive in the reorganization will be the same as your
      aggregate tax basis in the shares of EarthLink common stock or preferred
      stock or MindSpring common stock you surrender in the reorganization,
      decreased by the tax basis that is allocable to any fractional share of
      WWW Holdings common stock for which you receive cash;

    - the holding period of the shares of WWW Holdings common stock or preferred
      stock you receive in the reorganization will include the holding period of
      the shares of EarthLink common stock or preferred stock or MindSpring
      common stock that you surrender in the reorganization; and

    - if you receive cash instead of a fractional share of WWW Holdings common
      stock, you will recognize gain or loss equal to the difference between the
      amount of cash received and your tax basis that is allocable to the
      fractional share; the gain or loss you recognize generally will constitute
      capital gain or loss.

    The preceding description of federal income tax consequences references the
opinion of Hunton & Williams as to EarthLink and the EarthLink stockholders and
the opinion of Hogan & Hartson L.L.P. as to MindSpring and the MindSpring
stockholders.

    Receipt by EarthLink of substantially the same tax opinion of Hunton &
Williams as of the closing date and receipt by MindSpring of substantially the
same tax opinion of Hogan & Hartson L.L.P. as of the closing date are conditions
to consummation of the mergers of EarthLink and MindSpring into WWW Holdings.
These opinions are based on, and the opinions to be given as of the closing date
will be based on, customary assumptions and representations. Hunton & Williams'
opinion and Hogan & Hartson L.L.P.'s opinion represent their best legal judgment
and are not binding on the Internal Revenue Service or any court. If the mergers
of EarthLink and MindSpring into WWW Holdings do not qualify as a
reorganizations within the meaning of Section 368(a) of the Internal Revenue
Code, the exchange of stock in the mergers of EarthLink and MindSpring into WWW
Holdings would be taxable to EarthLink's stockholders and to MindSpring's
stockholders.

PROCEDURES FOR EXCHANGE OF STOCK CERTIFICATES

    WWW Holdings has appointed American Stock Transfer and Trust Co. as exchange
agent in connection with the reorganization. Immediately prior to the time the
mergers of EarthLink and MindSpring into WWW Holdings become effective, WWW
Holdings will deposit with American Stock Transfer, in trust for the benefit of
former EarthLink stockholders and former MindSpring stockholders, certificates
representing shares of WWW Holdings common stock to be issued and the cash to be
paid instead of fractional shares under the terms of the reorganization
agreement.

    Promptly after the reorganization is consummated, American Stock Transfer
will send to each former stockholder of EarthLink and MindSpring a letter and
instructions for exchanging the stockholder's EarthLink or MindSpring stock
certificates for the stock certificates of WWW Holdings. After the
reorganization becomes effective, shares of the EarthLink common stock and
preferred stock and the MindSpring common stock will represent only the right to
receive:

    - certificates representing shares of WWW Holdings common stock into which
      the stockholder's shares of EarthLink common stock or MindSpring common
      stock are converted; and

    - a check for any fractional share interests and any dividends or
      distributions as described below.

    The WWW Holdings common stock certificates and any checks will be delivered
to each former EarthLink common stockholder and each former MindSpring common
stockholder on receipt by American Stock Transfer of certificates representing
the stockholder's shares of EarthLink common stock and MindSpring common stock,
along with a properly completed letter transmitting the certificates. If any of
the certificates of EarthLink common stock or MindSpring common stock have been
lost, stolen or destroyed, the stockholder must deliver a bond reasonably
satisfactory to WWW Holdings and American Stock Transfer. No interest will be
paid on any cash to be paid instead of fractional shares.

    YOU SHOULD NOT SEND IN YOUR CERTIFICATES REPRESENTING EARTHLINK COMMON STOCK
OR PREFERRED STOCK OR MINDSPRING COMMON STOCK UNTIL YOU RECEIVE INSTRUCTIONS
FROM AMERICAN STOCK TRANSFER.

    None of EarthLink, MindSpring, WWW Holdings or American Stock Transfer will
be liable to any former EarthLink stockholder or former MindSpring stockholder
for any shares or cash delivered in good faith to a public official pursuant to
applicable abandoned property, escheat or similar laws.

    Until their outstanding certificates representing EarthLink common stock or
MindSpring common stock are surrendered, former stockholders of EarthLink and
former stockholders of MindSpring will not receive any dividends payable to WWW
Holdings stockholders for any period after the reorganization becomes effective.
When EarthLink stockholders and MindSpring stockholders surrender their
certificates formerly representing EarthLink common stock and MindSpring common
stock, the certificates will be canceled and exchanged for certificates of WWW
Holdings common stock and cash representing fractional shares. In addition, when
WWW Holdings stock certificates are issued to former common stockholders of
EarthLink and MindSpring, any dividend declared by WWW Holdings with a record
date for common stockholders entitled to receive the dividend on or after the
reorganization becomes effective and a date of payment prior to the date the
EarthLink or MindSpring certificates are surrendered will be paid promptly to
the former common stockholders. No interest will be paid on these dividends.

    American Stock Transfer may deduct any amounts required to be withheld under
federal, state, local or foreign income tax laws from any shares of common stock
or cash payments made to a former EarthLink or MindSpring stockholder. For
federal income tax purposes, former EarthLink stockholders and former MindSpring
stockholders will be treated as having received any amounts withheld by American
Stock Transfer.

INTERESTS OF EARTHLINK DIRECTORS AND OFFICERS IN THE REORGANIZATION

    In considering the recommendation of the EarthLink board of directors with
respect to the reorganization agreement, EarthLink stockholders should be aware
that various officers and directors of EarthLink, such as those identified
below, have interests in the reorganization that are in addition to, or
different from, their interests as stockholders of EarthLink generally. The
EarthLink board of directors was aware of these interests and considered them
along with other matters in recommending that EarthLink stockholders vote to
adopt the reorganization agreement.

    WWW HOLDINGS DIRECTORS AND MANAGEMENT


    The reorganization agreement provides that once the reorganization has taken
place, the board of directors of WWW Holdings will consist of 13 directors, four
of whom will be named by the EarthLink board. The EarthLink board has named four
of its existing members, Sky D. Dayton, Charles G. Betty, Linwood A. Lacy, Jr.
and Reed E. Slatkin as its four designees to the WWW Holdings board. The
reorganization agreement also provides that Charles G. Betty, EarthLink's
president and chief executive officer, will be the chief executive officer of
WWW Holdings. See "Management and Operation of WWW Holdings After the
Reorganization" beginning on page 170.


    EARTHLINK STOCK OPTIONS

    When the merger of EarthLink into WWW Holdings is consummated, each
outstanding option and warrant to purchase EarthLink common stock, including
options and warrants held by directors and officers, will be converted into an
option or a warrant, as the case may be, to purchase a number of shares of WWW
Holdings common stock equal to the number of shares covered by the option or
warrant, as the case may be, immediately prior to the merger multiplied by
1.615. The directors and officers of EarthLink held options and warrants to
purchase 1,929,404 shares of EarthLink common stock as of December 20, 1999.

    CONVERTIBLE SECURITIES VESTING PLAN

    In December 1997, EarthLink's board of directors adopted a plan under which
the vesting of stock options and warrants held by some of EarthLink's directors
and employees accelerate upon a change in control of EarthLink. Generally, a
change in control includes the sale of all or substantially all of EarthLink's
assets or the acquisition by a person or group (as that term is defined in
Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules
promulgated under the Securities Exchange Act of 1934) of 25% or more of
EarthLink's outstanding voting securities. The reorganization would constitute a
change in control for purposes of the vesting plan. As a result, some options
and warrants, including those held by Messrs. Dayton and Betty, will accelerate
and become fully exercisable upon the occurrence of the reorganization.

    KEY EMPLOYEE COMPENSATION CONTINUATION PLAN


    In January 1998 the EarthLink board of directors adopted a plan under which
those employees identified as "key" or critical to EarthLink are entitled to a
severance payment equal to fifty percent of their compensation and any other
benefits received during the twelve-month period ending upon their termination,
if the subject employees are terminated following a change in control of
EarthLink. The reorganization would constitute a change in control for purposes
of the compensation continuation plan. EarthLink adopted this plan to attract
the highest quality individuals to become key members of its leadership team and
to retain the high-quality individuals who were members of its leadership team
at the time of the adoption of the plan. Messrs. Dayton and Betty, among others,
are entitled to these benefits.


                                       58
<PAGE>
    INDEMNIFICATION AND INSURANCE

    Under the reorganization agreement, from the time that the reorganization
becomes effective, WWW Holdings must indemnify all of the former directors,
officers, employees and agents of both EarthLink and MindSpring to the fullest
extent permitted by the Delaware General Corporation Law for all acts or
omissions arising out of their service as directors, officers, employees and
agents, as trustees or fiduciaries of any plan for the benefit of the employees
of either company, or otherwise on behalf of either of the companies. WWW
Holdings must also advance expenses incurred by any of the persons identified
above in any proceeding or investigation in connection with any of their acts or
omissions.

    Also, WWW Holdings is required by the reorganization agreement to maintain
for at least six years directors' and officers' liability insurance for the
benefit of EarthLink's and MindSpring's directors and officers similar to the
directors' and officers' liability insurance currently provided by EarthLink and
MindSpring.

INTERESTS OF MINDSPRING DIRECTORS AND OFFICERS IN THE REORGANIZATION

    In considering the recommendation of the MindSpring board of directors with
respect to the reorganization agreement, MindSpring stockholders should be aware
that a number of officers and directors of MindSpring, such as those described
below, have interests in the reorganization that are in addition to, or
different from, their interests as stockholders of MindSpring generally. The
MindSpring board of directors was aware of these interests and considered them,
along with other matters in recommending that the MindSpring stockholders vote
to adopt the reorganization agreement.

    WWW HOLDINGS' DIRECTORS AND MANAGEMENT


    The reorganization agreement provides that once the reorganization has taken
place, the board of directors of WWW Holdings will consist of thirteen
directors, four of whom will be named by MindSpring's board. The MindSpring
board has named four of its existing members, Charles M. Brewer, Michael S.
McQuary, Campbell B. Lanier, III and William H. Scott, III, as its four
designees to the WWW Holdings board. The reorganization agreement also provides
that Charles M. Brewer, MindSpring's chairman and chief executive officer, will
be chairman of WWW Holdings, and Michael S. McQuary, MindSpring's president and
chief operating officer, will be president of WWW Holdings. See "Management and
Operations of WWW Holdings after the Reorganization" beginning on page 170.


    MINDSPRING STOCK OPTIONS

    When the merger of MindSpring into WWW Holdings is consummated, each
outstanding option to purchase MindSpring common stock, including options held
by directors and officers, will be converted into an option to purchase a number
of shares of WWW Holdings common stock equal to the number of shares covered by
the option immediately prior to the merger. The directors and executive officers
of MindSpring held options to purchase 1,226,664 shares of MindSpring common
stock as of December 20, 1999.

    INDEMNIFICATION AND INSURANCE

    Under the reorganization agreement, from the time that the reorganization
becomes effective, WWW Holdings must indemnify all of the former directors,
officers, employees and agents of both EarthLink and MindSpring to the fullest
extent permitted by the Delaware General Corporation Law for all acts or
omissions arising out of their service as directors, officers, employees and
agents, as trustees or fiduciaries of any plan for the benefit of the employees
of either company, or otherwise on behalf of either of the companies. WWW
Holdings must also advance expenses incurred by any of the

                                       59
<PAGE>
persons identified above in any proceeding or investigation in connection with
any of their acts or omissions.

    Also, WWW Holdings is required by the reorganization agreement to maintain
for at least six years directors' and officers' liability insurance for the
benefit of EarthLink's and MindSpring's directors and officers similar to the
directors' and officers' liability insurance currently provided by EarthLink and
MindSpring.

WORK FORCE AND EMPLOYEE BENEFIT MATTERS

    WWW Holdings intends to provide benefits to former EarthLink employees
employed by WWW Holdings that are substantially the same as those currently
provided to EarthLink employees. WWW Holdings intends to provide benefits to
former MindSpring employees employed by WWW Holdings that are substantially the
same as those currently provided to MindSpring employees.

HEADQUARTERS

    After the reorganization, WWW Holdings' corporate headquarters will be
located in Atlanta, Georgia.

EFFECTIVE TIME

    The closing of the transactions contemplated by the reorganization agreement
will take place at 11:00 a.m. on a date agreed upon by EarthLink, MindSpring and
WWW Holdings, which shall be no later than the third business day following the
date when all of the conditions to the obligations of EarthLink, MindSpring and
WWW Holdings set forth in the reorganization agreement have been satisfied or
waived. On the date of the closing, EarthLink and WWW Holdings will file a
certificate of merger with the Secretary of State of the State of Delaware under
which EarthLink will be merged into WWW Holdings. When the certificate of merger
is deemed filed by the Delaware Secretary of State, MindSpring and WWW Holdings
immediately will file a certificate of merger under which MindSpring will be
merged into WWW Holdings. The reorganization will become effective when the
second certificate of merger is deemed filed by the Delaware Secretary of State.

REGULATORY APPROVALS REQUIRED TO COMPLETE THE REORGANIZATION

    ANTITRUST CLEARANCE

    The Hart-Scott-Rodino Antitrust Improvements Act of 1976 and its related
rules and regulations prohibit EarthLink, MindSpring and WWW Holdings from
completing the reorganization until EarthLink and MindSpring make a filing with
the Antitrust Division of the Department of Justice and the Federal Trade
Commission and the specified Hart-Scott-Rodino Antitrust Improvements Act
waiting period requirements have been satisfied. Even after the waiting period
expires or terminates, the Antitrust Division or the Federal Trade Commission
may later challenge the reorganization on antitrust grounds. If the
reorganization is not completed within 12 months after the expiration or earlier
termination of the initial waiting period, EarthLink and MindSpring will be
required to submit new information to the Antitrust Division and the Federal
Trade Commission, and a new waiting period would begin. EarthLink and MindSpring
made the filing with the Department of Justice and the Federal Trade Commission
on October 20, 1999, and received notice on November 3, 1999 that the waiting
period had been terminated.

SPRINT GOVERNANCE AGREEMENT

    GENERAL

    EarthLink and Sprint entered into a governance agreement, forming a
strategic alliance in the area of Internet access and related services. The
governance agreement establishes terms and conditions concerning:

    - EarthLink's corporate governance;

    - the acquisition and disposition of EarthLink's equity securities by
      Sprint, Sprint L.P. and any of their affiliates;

    - the rights of Sprint, Sprint L.P. and any of their affiliates to purchase
      EarthLink's outstanding securities; and

    - the rights of EarthLink's Board of Directors to solicit, receive and
      entertain offers to effect business combinations.

    The following is a summary of the material terms of the Sprint governance
agreement.

    CORPORATE GOVERNANCE AND ELECTION OF DIRECTORS

    The governance agreement provides that EarthLink's board of directors will
determine the fundamental policies and strategic direction of EarthLink.
Consistent with the voting rights granted to the holders of EarthLink's
series A convertible preferred stock, the governance agreement authorizes
Sprint, as the holder of all of the outstanding shares of series A convertible
preferred stock, to designate two directors to sit on the board of directors of
EarthLink. Following the conversion or redemption of EarthLink's series A
convertible preferred stock into common stock, EarthLink is obligated to elect
up to two Sprint nominees for director to the EarthLink board of directors. As
long as Sprint has the right to designate nominees to the board, Sprint is also
entitled to appoint one of its designated directors to any strategic business
and planning committee, finance committee or other significant committee of the
EarthLink board of directors. If no committees like the ones described in the
preceding sentence exist, the governance agreement gives Sprint a reasonable
opportunity to review and discuss EarthLink's strategic and business plans and
financing plans with EarthLink's management before those plans are submitted to
EarthLink's board of directors. Sprint is also entitled to receive advance
copies of information and materials to be provided to EarthLink's board of
directors with respect to those matters. However, no director appointed by
Sprint is entitled to participate on any committee of EarthLink's board of
directors or the board of any significant subsidiary of EarthLink that is
created for the purpose of considering a business combination or any related
matters, or to participate in the EarthLink board's deliberations about a
business combination. Consistent with the voting rights granted to the holders
of the series A convertible preferred stock of EarthLink, Sprint is entitled to
designate two directors for so long as it holds 20% or more of EarthLink's fully
diluted outstanding stock and one director for so long as it holds 10% or more
of EarthLink's fully diluted outstanding stock. The governance agreement allows
upward adjustments to Sprint's ownership percentage for those dilutive events
described in the governance agreement.

    If EarthLink's series A convertible preferred stock has been converted into
common stock, EarthLink must use its best efforts to solicit proxies from its
stockholders in favor of Sprint's nominees for directors. The governance
agreement also obligates Sprint, Sprint L.P. and their affiliates to vote in
favor of any other nominee or director selected by EarthLink's board of
directors. Sprint and Sprint L.P.'s voting obligations are supported by an
irrevocable proxy that Sprint and Sprint L.P. granted to EarthLink.

    For so long as Sprint, Sprint L.P. and their affiliates' combined equity
stake in EarthLink, when expressed as a percentage of EarthLink's fully-diluted
outstanding stock, exceeds 10%, EarthLink is

                                       61
<PAGE>
prohibited from taking or authorizing various actions without the approval of
all of the directors designated by Sprint. These actions include:

    - the execution or performance of corporate acts or transactions that would
      discriminate against Sprint, Sprint L.P. and their affiliates as
      stockholders of EarthLink;

    - the issuance of any class or series of EarthLink's stock that provides for
      voting rights in excess of one vote per share;

    - EarthLink or any significant subsidiary of EarthLink engaging in business
      activities substantially beyond its current general field of enterprise;
      or

    - EarthLink's issuance of equity securities in connection with various
      business combinations.

    EQUITY PURCHASES FROM EARTHLINK; SUBSCRIPTION RIGHTS

    So long as Sprint owns at least 17.8% of the outstanding stock of EarthLink
on a fully diluted basis, subject to adjustment for dilutive events described in
the governance agreement and for EarthLink's accumulation of indebtedness under
its convertible debt financing, Sprint, Sprint L.P. and their affiliates have
anti-dilution and subscription rights under the governance agreement. In
addition to their being able to subscribe for stock directly from EarthLink,
Sprint, Sprint L.P. and their affiliates may effect their anti-dilution rights
by making purchases of EarthLink's equity securities at any time from any other
EarthLink stockholder, as long as after giving effect to the purchases, Sprint's
percentage interest in the outstanding stock of EarthLink on a fully diluted
basis, is less than or equal to an amount determined by a formula set forth in
the governance agreement that limits the maximum equity stake that Sprint,
Sprint L.P. and their affiliates may have in EarthLink.

    If Sprint's ownership interest in the outstanding stock of EarthLink on a
fully diluted basis exceeds 17.8%, as adjusted under the terms of the governance
agreement, before EarthLink may issue new equity securities, other than in
connection with a business combination, EarthLink must provide Sprint written
notice of EarthLink's intention to issue new equity securities at least five
business days before the EarthLink board of directors' meeting authorizing the
issuance. Sprint has ten business days after receiving EarthLink's notice to
purchase a portion of the issuance, as determined by the formula described in
the preceding paragraph, and if Sprint does so, the new equity securities
offered under the notice will be issued and sold to Sprint by EarthLink at the
same time and on the same terms and conditions as the equity securities would be
sold to third parties. If the new equity securities would be sold in an
underwritten public offering, Sprint could purchase a portion of the securities
offered determined by the formula described in the preceding paragraph at a per
share price equal to the per share price that EarthLink would have sold the
shares of the new equity securities to the underwriters. If for any reason the
issuance of the new equity securities to third parties were not consummated,
Sprint's right to purchase its share of the issuance would lapse.

    Sprint's subscription rights generally do not apply to the issuance of
EarthLink's securities in connection with a business combination. However, if
EarthLink determines that Sprint's percentage interest in the outstanding stock
of EarthLink on a fully diluted basis has decreased by five percent or more as a
result of issuances relating to business combinations, EarthLink must notify
Sprint. No later than the second anniversary following Sprint's receipt of
EarthLink's notice, EarthLink must make written offers to Sprint to purchase, in
the aggregate, a number of shares sufficient to bring Sprint's percentage
interest in the outstanding stock of EarthLink on a fully diluted basis up to
its percentage interest before the issuance of the equity securities relating to
the business combinations. The offer is to be made at a purchase price equal to
the average stock price for common stock for the ten trading days before the
date of the issuance, less the underwriting discount applied in the most recent
underwritten offering of common stock. Sprint may accept an offer within five
days after receiving it.

                                       62
<PAGE>
    If EarthLink determines after giving effect to any and all offers to Sprint
described in the preceding paragraph that Sprint's percentage interest in the
outstanding stock of EarthLink on a fully diluted basis has decreased by 0.10 or
more solely as a result of the issuance of equity securities in connection with
a business combination, EarthLink will be obligated to make one or more offers
with respect to not less than the aggregate number of shares of EarthLink stock
that EarthLink is obligated to offer to Sprint pursuant to the foregoing
paragraph resulting from all issuances of equity securities in connection with a
business combination as then calculated, at the earlier of: the passage of two
years from the date of the notice to Sprint described in the preceding
paragraph, or six months after the date Sprint receives notice from EarthLink.
However, in no event is EarthLink obligated to make Sprint an offer that, after
giving effect to the offer, would cause Sprint's percentage interest in the
outstanding EarthLink stock on a fully diluted basis to exceed the formula
described above that limits the maximum equity stake that Sprint, Sprint L.P.
and their affiliates may have in EarthLink.

    In addition, with respect to a purchase of new equity securities under
Sprint's anti-dilution rights discussed above, Sprint may, at its option,
purchase new equity securities in the form of shares of a new series of
EarthLink preferred stock having terms that are structured and priced in the
same manner as the EarthLink series A convertible preferred stock. The terms are
determined by reference to the average stock price for a share of EarthLink
common stock for the 30 trading days before the date of issuance of the shares
of the new series. Sprint's purchase of new equity securities in the form of the
shares of the new series are limited:

    - to not more than 75% of any issuance of new EarthLink equity securities
      from the date that Sprint purchased the EarthLink series A preferred stock
      to the second anniversary of that date;


    - to not more than 66.67% of any issuance of new EarthLink equity securities
      after the second anniversary of date of the purchase by Sprint of
      EarthLink's series A preferred stock until the third anniversary of that
      purchase; and


    - after the third anniversary, EarthLink is not obligated to issue any new
      EarthLink equity securities in the form of a new series of preferred
      stock.

    STANDSTILL PROVISIONS

    The governance agreement restricts Sprint, Sprint L.P. and their affiliates'
ability to acquire or dispose of EarthLink equity securities. These restrictions
are summarized as follows:

    Except for purchases of shares and related activities by Sprint otherwise
permitted under the governance agreement, Sprint, Sprint L.P. and their
affiliates may not, directly or indirectly:

    - acquire, offer to acquire or agree to acquire any of EarthLink's equity
      securities, or any equity securities of any subsidiary of EarthLink, or
      EarthLink or its subsidiaries' material assets;

    - make or participate in any solicitation of proxies or otherwise seek to
      influence any person with respect to the voting of any EarthLink equity
      securities that provide for voting rights;

    - make any public announcement regarding, or submit a proposal for, or offer
      to effect any purchase of any significant portion of the assets of
      EarthLink or any subsidiary or division of EarthLink, any tender or
      exchange offer for any EarthLink equity securities, or a merger,
      consolidation or other extraordinary transaction involving EarthLink or
      Sprint, Sprint's L.P.'s or either of their affiliates' shares of
      EarthLink's equity securities;

    - form, join or in any way participate in a "group" as defined in
      Rule 13d-5(b) under the Securities Exchange Act of 1934; or

    - request EarthLink or any of its representatives to amend or waive any of
      the above-mentioned provisions.

                                       63
<PAGE>
    In addition, none of Sprint, Sprint L.P. or their affiliates may, directly
or indirectly, sell, transfer or otherwise dispose of any of EarthLink's equity
securities except under a registered underwritten public offering in accordance
with the registration rights agreement among EarthLink, Sprint and Sprint L.P.,
in accordance with certain exemptions from registration under the Securities Act
of 1933, and to any direct or indirect subsidiary of Sprint. Under no
circumstances may Sprint, Sprint L.P. or any of their affiliates sell, transfer
or otherwise dispose of any equity securities of EarthLink to any purchaser if,
after giving effect to the sale, the purchaser would, to Sprint's knowledge,
own, or have the right to acquire, 5% or more of the equity securities of
EarthLink then outstanding. This restriction does not apply in cases where the
purchaser would not reasonably be anticipated to be obligated by virtue of the
purchase to file a Schedule 13D with the Securities and Exchange Commission
under each of paragraphs (b) and (e) of Rule 13d-1 of the Securities Exchange
Act of 1934.

    PURCHASES OF ADDITIONAL EQUITY SECURITIES; BUSINESS COMBINATIONS

    During the period from September 5, 2001 to September 5, 2003, Sprint will
have the right to make an offer to purchase all, but not less than all, of
EarthLink's outstanding equity securities at a per share price equal to the per
share price determined by dividing the aggregate private market equity value
that an unrelated third party would pay if it were to acquire all of EarthLink's
outstanding equity securities, including those equity securities held by Sprint,
Sprint L.P. and their affiliates, in an arm's length transaction, assuming that
all credible buyers are given an equal opportunity by EarthLink to make a
proposal to acquire directly or indirectly beneficial ownership of 20% or more
of EarthLink's equity securities, the absence of any commercial relations
between EarthLink and Sprint and its affiliates, and the absence of any
ownership stake in EarthLink by Sprint, Sprint L.P. and their affiliates, by the
total number of shares of EarthLink common stock outstanding on a fully diluted
basis.

    This fair private market value is to be determined as follows: the
respective boards of EarthLink and Sprint will negotiate the amount of the fair
private market value to be paid under Sprint's offer. If the two parties are
unable to agree on this amount, within 30 days after the submission of Sprint's
offer to EarthLink's board of directors, the parties will agree to be bound to
the valuation determined under the following formula: two appraisals will be
made by recognized investment banks, one selected by each of Sprint and
EarthLink; if the lower of the appraisals is more than 10% less than the higher,
a third independent valuation will be made by an investment bank jointly
selected by EarthLink and Sprint; otherwise, the fair private market value will
be the average of the first two appraisals; and if the third independent
valuation differs in either direction by more than 5% of the average of the
values obtained by the initial appraisals, the fair private market value will be
deemed to equal the average of the two closest valuations. If the third
independent valuation differs from the average of the first two appraisals by
less than 5%, then the third independent valuation will be the fair private
market value.

    Sprint's offer may not be subject to any financing contingency, and will be
reflected in a form of definitive agreement that Sprint is prepared to execute.
The conditions to consummation of Sprint's offer and the representations and
warranties incorporated within the offer will be reasonable and customary for
transactions in which a similarly situated stockholder offers to purchase all of
the equity securities not held by that stockholder or its affiliates.

    The EarthLink board will have a one-time right, exercisable within 14 days
after receipt of Sprint's offer, to cause Sprint to postpone the making of that
offer for nine months. If EarthLink exercises that right, Sprint is obligated to
withdraw its offer for a period of nine months, but the period in which Sprint
can make an offer will be extended until June 5, 2004, and EarthLink's exercise
of its postponement right will not limit Sprint's right to respond to a
"third-party offer" as explained below.

    When the fair private market value of EarthLink's outstanding equity
securities is determined, Sprint generally will be obligated to extend an offer
to buy all of EarthLink's outstanding equity

                                       64
<PAGE>
securities, but, subject to various limitations, Sprint has a one-time right to
rescind its offer. Sprint must exercise this right within 14 days after receipt
of the determination of the fair private market value. If Sprint chooses to
proceed with its offer, EarthLink's board of directors will support Sprint's
offer by approving and recommending the offer to its stockholders and will cause
EarthLink to take all steps reasonable and necessary to facilitate consummation
of the offer, unless a third party offer determined by the EarthLink board of
directors to be an offer for greater aggregate consideration than Sprint's offer
is also outstanding. Once a third party offer is determined to be for greater
aggregate consideration than the offer proposed by Sprint, Sprint will be
released from its obligation to proceed with its offer, and likewise EarthLink
will be released from its obligation to support and facilitate the consummation
of Sprint's offer. If the third party is in the form of a tender offer, at the
consummation of the tender offer, the offeror will have an option to purchase
from Sprint, Sprint L.P. and any of their affiliates, at the tender offer price,
the number of EarthLink equity securities equal to the quotient of the number of
shares of outstanding EarthLink voting equity securities owned by parties other
than Sprint, Sprint L.P. or their affiliates and tendered and accepted in the
offer, divided by the number of shares of EarthLink voting equity securities
owned by parties other than Sprint, Sprint L.P. or their affiliates, multiplied
by the number of shares of EarthLink voting equity securities owned by Sprint,
Sprint L.P. and their affiliates on the expiration date of the tender offer. In
addition if the offer or a related matter must be approved by EarthLink's
stockholders in order for it to be effectuated, Sprint, Sprint L.P. and their
affiliates are obligated, subject to limited exceptions, to cast in favor of the
offer and any related matters that number of votes as is equal to the number of
EarthLink equity securities that they would be obligated to sell under the
formula described above. Sprint, Sprint L.P. and their affiliates are not
entitled to exercise dissenters' rights of appraisal for any business
combination effected in connection with a third party offer described in this
paragraph.

    THIRD-PARTY OFFERS

    EarthLink is obligated to provide Sprint with prompt written notice of its
receipt of a bona fide written offer to effect a business combination from a
third party. After receiving an offer from a third party, EarthLink's board must
determine whether it intends to recommend the offer to the EarthLink
stockholders or whether the offer is not in the best interests of its
stockholders, in which event it does not intend to recommend the offer to its
stockholders.

    For a period of ten days following EarthLink's giving Sprint notice of
receipt of an offer received by a third party, EarthLink may not enter into a
definitive agreement relating to that offer. During that time, Sprint has an
option to make an offer with respect to either a third-party offer that the
EarthLink board recommended to its stockholders or if the board of directors of
Sprint reasonably determines that the conditions to the third-party offer are
reasonably likely to be satisfied and that the third-party offer would
ultimately be consummated, a third-party offer that the EarthLink board has not
recommended to its stockholders. The offer must be made by Sprint, Sprint L.P.
and any of their affiliates to acquire all of the equity securities of EarthLink
not already owned by Sprint, Sprint L.P. and their affiliates at a per share
price in excess of the equivalent per share price set forth in the offer from
the third party. Sprint's offer must be in the form of a definitive agreement
that Sprint, Sprint L.P. and any of their affiliates are prepared to execute,
and the conditions to the consummation of the offer and the representations,
warranties and covenants incorporated in the offer must be customary for
transactions in which a similarly situated stockholder offers to purchase all of
EarthLink's equity securities not held by that stockholder, and may not, in any
event, be more cumbersome in any material respect than those warranties and
representations included in the offer that EarthLink receives from a third
party.

    EarthLink may not adopt any takeover defenses, enter into any agreement or
take any other action in connection with a third-party offer recommended by the
EarthLink board that would materially impair Sprint, Sprint LP. or any of their
affiliates' ability to make and consummate their own offer or

                                       65
<PAGE>
materially increase Sprint's, Sprint L.P.'s or any of their affiliates' cost of
consummating an offer. However, EarthLink is permitted to enter into a
definitive agreement with respect to an EarthLink board recommended third-party
offer that provides for a termination fee that does not exceed 3% of the
consideration to be received per share of common stock multiplied by the number
of shares EarthLink's common stock outstanding on a fully diluted basis, less
the number of shares beneficially owned by the offering party, plus customary
fees and expenses. Nevertheless, the definitive agreement with respect to the
recommended third-party offer must provide that the fees and expenses will not
be payable if Sprint makes an offer complying with the requirements set forth in
the preceding paragraph within 72 hours of the first public announcement of the
recommended third-party offer.

    If Sprint has the option to make an offer and exercises its option more than
five days before the date of an EarthLink stockholders' meeting held to consider
a third-party offer, then EarthLink will, unless an offer that the EarthLink
board determines to be for a greater aggregate consideration than Sprint's offer
is then outstanding, support Sprint's offer by approving and recommending it to
the EarthLink's stockholders and cause EarthLink to take all steps reasonable
and necessary to facilitate consummation of Sprint's offer. If a third-party
offer is made subsequent to Sprint's offer that is determined by EarthLink's
board to be for greater aggregate consideration than Sprint's offer, EarthLink's
obligations to support and facilitate Sprint's offer will terminate and
EarthLink will be free to consider and act upon the third-party offer. Sprint is
nonetheless entitled, at any time prior to the consummation of the third-party
offer, to make another offer to purchase all of EarthLink's outstanding equity
securities on a fully diluted basis, at a price per share in excess of the
equivalent per share price set forth in the third-party offer.

    If a third-party offer for a business combination that is recommended by
EarthLink's board of directors is undertaken in the form of a tender offer, at
the consummation of the tender offer, the offeror will have an option to
purchase from Sprint, Sprint L.P. or any of their affiliates, at the tender
offer price, in the aggregate, the number of EarthLink equity securities equal
to the quotient of the number of shares of EarthLink voting equity securities
owned by parties other than Sprint, Sprint L.P. or their affiliates and tendered
and accepted in the offer, divided by the number of shares of EarthLink voting
equity securities owned by parties other than Sprint, Sprint L.P. or their
affiliates, multiplied by the number of shares of EarthLink voting equity
securities owned by Sprint, Sprint L.P. and their affiliates on the expiration
date of the tender offer, less the number of EarthLink's equity securities that
have already been tendered to the offeror by Sprint, Sprint L.P. and any of
their affiliates. In addition, if a third-party offer recommended to the
EarthLink stockholders by EarthLink's board or any related matters must be
approved by EarthLink's stockholders in order for such offer to be effectuated,
Sprint, Sprint L.P. and their respective affiliates are obligated, subject to
limited exceptions, to cast in favor of such offer and any such related matter
the number of votes as is equal to the number of EarthLink equity securities
determined by the formula set forth in the preceding sentence. None of Sprint,
Sprint L.P. or their affiliates are entitled to exercise dissenters' rights of
appraisal with respect to any business combination effected in connection with a
third-party offer that is recommended by EarthLink's board to EarthLink's
stockholders.

    SOLICITATION OF OFFERS

    From June 5, 1998 until the earlier of September 5, 2000 or the termination
of the governance agreement under its terms, EarthLink may not, directly or
indirectly solicit or initiate, or encourage the submission of, any proposal for
a tender or exchange offer, a merger, consolidation share exchange or other
business combination or a proposal to acquire 20% or more of EarthLink's voting
equity securities or a proposal to acquire assets of EarthLink for consideration
equal to 20% of EarthLink's market capitalization as of the date of the
proposal, nor may EarthLink participate in any discussions or negotiations
regarding, or take any action that may reasonably be expected to lead to, any
proposal for a tender or exchange offer, a merger, consolidation share exchange
or other business combination

                                       66
<PAGE>
or a proposal to acquire 20% or more of EarthLink's voting equity securities or
a proposal to acquire assets of EarthLink for consideration equal to 20% of
EarthLink's market capitalization as of the date of the proposal. However, to
the extent required by the fiduciary obligations of the EarthLink board of
directors, as determined in good faith by the EarthLink board based on the
advice of outside counsel, EarthLink may furnish information in response to any
unsolicited requests therefor and discuss the information. Following delivery to
Sprint of notice of the proposal, EarthLink may participate in negotiations
regarding the proposal and enter into an agreement relating to the proposal or
take any other action ancillary to the entering into the Agreement.

    After September 5, 2000 and until the earlier of the September 5, 2001 or
the termination of the governance agreement in accordance with its terms,
EarthLink may not, directly or indirectly, take any of the actions identified in
the forepart of the prior paragraph except through an investment banking firm
EarthLink formally engages for that purpose; but, 30 days before engaging an
investment banking firm, EarthLink must notify Sprint of its intention to engage
an investment banking firm, and for so long as the investment banking firm
remains engaged by EarthLink for that specific purpose, Sprint will be permitted
to prepare and make an offer to purchase all of the outstanding EarthLink equity
securities at a price determined by dividing the fair private market value of
the shares, as determined by a valuation method set forth in the governance
agreement, by the number of shares of EarthLink common stock outstanding on a
fully dilated basis. Subject to the terms of Sprint's offer, and unless a
third-party offer for better aggregate consideration is then outstanding, Sprint
is entitled to pursue its offer for as long as necessary to permit it to be
consummated. EarthLink is obligated to furnish Sprint with copies of all
information provided by EarthLink to its investment banking firm, subject to
Sprint entering into a customary confidentiality agreement with respect to that
information.

    EarthLink's board of directors would be obligated under the governance
agreement to:

    - promptly notify Sprint in writing of its receipt of a proposal for a
      tender or exchange offer, merger, consolidation share exchange or other
      business combination or a proposal to acquire 20% or more of EarthLink's
      voting equity securities or a proposal to acquire assets of EarthLink for
      consideration equal to 20% of EarthLink's market capitalization as of the

      confidence, make available to Sprint all information made available to the
      party making the proposal described in the preceding two paragraphs at the
      same time it is provided to the party.

    EarthLink generally is obligated under the governance agreement not to take
any action or omit to take any action that would result in Sprint, Sprint L.P.
or any of their affiliates being deemed an "acquiring person" or similar
designation under any stockholders' rights plan, that would result in

                                       67
<PAGE>
Sprint, Sprint L.P. or any of their affiliates being prejudiced under any
applicable state takeover statute, including Section 203 of the Delaware General
Corporation Law, or that would otherwise cause any takeover defense to
materially impair or obstruct, or prevent, either legally or financially, the
exercise by Sprint, Sprint L.P. or any of their affiliates of rights granted
under article IV of the governance agreement, which governs Sprint's purchase of
additional securities and Sprint's and EarthLink's rights relating to mergers,
share exchanges and other extraordinary business combinations.

    STOCKHOLDERS' AGREEMENT; IRREVOCABLE PROXIES

    In order to provide for the enforcement of various aspects of the governance
agreement, Sprint and the following EarthLink principal stockholders have
entered into a stockholders' agreement: Sky Dayton, chairman of the EarthLink
board of directors; Quantum Industrial Partners LDC; Reed Slatkin, a director of
EarthLink; Kevin M. O'Donnell, a director of the EarthLink; Sidney Azeez, a
director of EarthLink; and George Soros. Further, in order to provide for
enforcement of the stockholders' agreement and the provisions of the governance
agreement requiring Sprint, Sprint L.P. and their affiliates to vote their
voting equity securities of EarthLink in accordance with the terms of the
governance agreement, Sprint has provided EarthLink an irrevocable proxy.

    TERMINATION; SURVIVAL

    The governance agreement terminates upon the earliest to occur of the
following events:

    - such time as Sprint's percentage interest in EarthLink's outstanding
      equity securities is greater than 90% or less than 10%, subject to
      adjustment for various dilutive events;

    - September 5, 2003;

    - the first date on which any person or "group" as defined in Rule 13d-5(b)
      of the Securities Exchange Act of 1934 is determined either to
      beneficially own or control more than 35% of EarthLink's outstanding
      equity securities by virtue of the acquisition of the securities pursuant
      to a third-party offer, if the rights granted and process contemplated by
      Article IV of the governance agreement have been observed and effected in
      accordance with the terms thereof, or to beneficially own or control 50%
      or more of EarthLink's outstanding voting equity securities;

    - upon the termination of EarthLink's marketing and distribution agreement
      with Sprint in various circumstances; or

    - upon the exercise of demand or incidental registration rights by any
      "holder" of "Registrable Securities" under the registration rights
      agreement entered into among EarthLink, Sprint and Sprint L.P.

    Even if the governance agreement terminates upon the occurrence of one of
the events listed above, Sprint will still be subject to the standstill
provisions described above until June 5, 2004 and thereafter for so long as
Sprint's combined equity stake in EarthLink exceeds 10% of EarthLink's fully
diluted outstanding stock. Sprint will maintain the governance and anti-dilution
rights described above under "Corporate Governance and Election of Directors"
and "Equity Purchases from EarthLink; Subscription Rights" following the
termination of the governance agreement. Further, if the governance agreement
terminates, the standstill provisions and various other provisions, including
the definitions section, will remain valid until Sprint's percentage interest in
EarthLink's outstanding equity securities falls below 10%, but, during any
period in which the standstill provisions survive, Sprint and its affiliates may
directly approach EarthLink's board in order to make an offer to effect a
business combination.

    WWW HOLDINGS TO BE BOUND BY THE GOVERNANCE AGREEMENT

    Upon the consummation of the Merger of EarthLink into WWW Holdings, WWW
Holdings will be bound by the provisions of the governance agreement. If the
proposed purchase of Sprint by MCI WorldCom Inc. is consummated, MCI WorldCom
will succeed to Sprint's rights and obligations under the governance agreement.

              TERMS AND CONDITIONS OF THE REORGANIZATION AGREEMENT

    Although this section describes the material provisions of the
reorganization agreement, it does not purport to describe all of its provisions.
A copy of the reorganization agreement is attached to this joint proxy
statement/prospectus as ANNEX A, and is incorporated in this document by
reference. All stockholders are urged to read the entire reorganization
agreement carefully.

    STRUCTURE.  As part of the reorganization, EarthLink will be merged into WWW
Holdings, and, immediately thereafter, MindSpring will be merged into WWW
Holdings, with WWW Holdings being the surviving corporation of both mergers. As
a result, EarthLink and MindSpring will cease to exist.

    NAME.  As a result of the merger of EarthLink and MindSpring into WWW
Holdings, WWW Holdings will be re-named "EarthLink, Inc."

    SHARE CONVERSION.  Under the terms of the reorganization agreement, each
stockholder of EarthLink will receive 1.615 shares of WWW Holdings common stock
in exchange for each share of EarthLink common stock held, 1.615 shares of WWW
Holdings series A convertible preferred stock for each share of EarthLink
series A convertible preferred stock held, 1.615 shares of WWW Holdings
series B convertible preferred stock for each share of EarthLink series B
convertible preferred stock held and 1.615 shares of WWW Holdings series C
convertible preferred stock for each share of EarthLink series C convertible
preferred stock held. Each MindSpring stockholder will receive one share of WWW
Holdings common stock for each share of MindSpring common stock held. Cash will
be paid instead of issuing any fraction of a share of WWW Holdings common stock.

    STOCK OPTIONS.  Each outstanding option to purchase EarthLink common stock
as of the effective time of the mergers will become an option to acquire a
number of shares of WWW Holdings common stock equal to the number of shares
purchasable under the EarthLink option multiplied by 1.615 at a per share price
equal to the exercise price under the EarthLink option divided by 1.615. Each
outstanding option to purchase MindSpring common stock as of the effective time
of the mergers will become an option to acquire a number of shares of WWW
Holdings common stock equal to the number of shares purchasable under the
MindSpring option at a per share price equal to the exercise price under the
MindSpring option. Upon the exercise of any converted option, cash will be paid
instead of issuing any fraction of a share of WWW Holdings common stock.

any purchase of 10% or more of the assets or any class of securities of,
EarthLink or MindSpring, as the case may be.

    Notwithstanding the preceding paragraph, the boards of directors of each of
EarthLink and MindSpring may comply with the securities laws in connection with
an acquisition proposal. The EarthLink and MindSpring boards also may furnish
information or enter into negotiations regarding an unsolicited proposal if the
following conditions are met:

    - the board of directors determines in good faith, taking into account the
      advice of outside counsel, that furnishing information or entering into
      negotiations is reasonably likely to be required for the board of
      directors to comply with its fiduciary duties to its stockholders;

    - the party receiving the proposal notifies the other party of the proposal,
      the identity of the person making the proposal and the party's intention
      to provide information or commence discussions and the party receiving the
      proposal keeps the other party informed of the status of the discussions;
      and

      with the person making the proposal that is on no more favorable terms
      than the confidentiality agreement between EarthLink and MindSpring.

described below, the board of directors of either EarthLink or MindSpring may
withdraw its recommendation of the reorganization agreement and recommend a
superior proposal. For purposes of the reorganization agreement, a superior
proposal is a proposal:

    - that has no financing contingency;

    - that is for more than 75% of the aggregate voting power of the outstanding
      equity securities of the party receiving the proposal;

                                       72
<PAGE>
    - that the board of directors of the party receiving the proposal believes
      in good faith:

        to be superior, from a financial point of view, to the proposal
        contained in the reorganization agreement, taking into account the
        advice of the party's outside financial advisors; and

        to be more favorable generally to the party's stockholders, taking into
        account all relevant factors, including legal, financial, regulatory and
        other aspects of the proposals and the conditions, prospects and time
        required for completion; and

    - that the board of directors has determined in good faith, taking into
      account the advice of outside legal counsel, that it is reasonably likely
      to be required to recommend the proposal in order to comply with its
      fiduciary duties to its stockholders.

The board of directors of either party may withdraw its recommendation of the
reorganization agreement and recommend a superior proposal:

    - if the board gives the other party at least four business days' written
      notice of its intention to withdraw its recommendation; and

    - if the board of directors determines in good faith, taking into account
      the advice of its outside financial advisors, that any counter-proposal
      delivered by the other party during this four day period is not at least
      as favorable to the party's stockholders as the superior proposal, taking
      into account all relevant factors.

    MUTUAL COVENANTS.  The reorganization agreement also contains other
agreements relating to the conduct of the parties prior to the effective time,
including those requiring the parties:

    - to prepare the WWW Holdings registration statement and this joint proxy
      statement/prospectus and to cause WWW Holdings to take any required action
      under state securities laws in connection with the issuance of WWW
      Holdings common stock in the reorganization;

    - to cooperate to make any required governmental filing and to obtain all
      required third-party consents;

      National Market with the ticker symbol "ELNK"; and

    - to consult with one another before issuing a press release or making any
      public statement regarding the reorganization agreement, except as
      required by applicable law or any listing agreement with any national
      securities exchange association.

    Each of EarthLink and MindSpring has agreed to provide the other with access
to its offices and information subject to EarthLink's and MindSpring's
obligations of confidentiality undertaken in connection with the reorganization
agreement.

    Each of the parties has agreed to notify the other party of:

    - any communication from a governmental entity with respect to the
      transactions contemplated by the reorganization agreement; and

    - any actions, suits or investigations commenced or, to the knowledge of the
      party threatened, against the party.


    Each party has agreed that it will use it best efforts to cause the
reorganization to receive tax-free treatment, other than the taxes resulting
from the payment of cash instead of issuing fractional shares, as described in
this joint proxy statement/prospectus in the section entitled "Material Federal
Income


                                       73
<PAGE>

Tax Considerations" beginning on page 55, and to qualify for "pooling of
interests" accounting treatment, as described in the section entitled
"Accounting for the Reorganization under the Pooling of Interests Method"
beginning on page 55.


    CONFIDENTIALITY.  Each party has agreed that it will hold, and will cause
its representatives to hold, in confidence, all information received in
connection with the transactions contemplated by the reorganization agreement.
The parties will not be subject to this obligation with respect to any
information:

    - that is or becomes generally available to the public other than as a
      result of a disclosure of the party receiving the information in
      connection with the reorganization agreement;

    - that was previously available to the party receiving the information on a
      non-confidential basis; or

    - that becomes available to the party on a non-confidential basis from an
      outside source that is not known to the party receiving the information to
      be contractually or legally prohibited from disclosing the information.

    If the reorganization agreement is terminated, each party will use its best
efforts to cause the documents and other materials subject to the
confidentiality obligations to be destroyed or returned.

    STANDSTILL.  Each of EarthLink and MindSpring has agreed that for two years
following any termination of the reorganization agreement it will not and it
will cause its affiliates not to:

    - except pursuant to the stock option agreements entered into with one
      another, acquire or seek to acquire, directly or indirectly, beneficial
      ownership of any assets or more than 5% of any class of securities of the
      other party or its affiliates, or any rights or options to acquire any
      assets or more than 5% of any class of securities of the other party or
      its affiliates;

    - make or participate in any solicitation of proxies relating to the voting
      securities of the other party or seek to encourage or influence any person
      with respect to the voting of any voting securities of the other party;

      other party;

      the Securities Exchange Act of 1934 with respect to the voting securities
      of the other party;

    - participate in any way in any tender offer, exchange offer, merger or
      other business combination involving the other party; or

    - act alone or in concert to control or influence the other party or the
      management, board of directors, policies or affairs of the other party.

      owe;

    - the party terminates the reorganization agreement because of the willful
      breach of the reorganization agreement by the other party; or

                        PRO FORMA FINANCIAL INFORMATION

    The following unaudited pro forma condensed combined financial statements
present the effect of the proposed reorganization of EarthLink and MindSpring,
accounted for as a pooling of interests, and the January 5, 2000 investment by
Apple Computer of $200 million in EarthLink. The EarthLink and MindSpring
unaudited pro forma condensed combined financial statements are based on the
historical consolidated financial statements of each company and the related
notes, which are incorporated by reference into this presentation. The unaudited
pro forma condensed combined balance sheet presents the combined financial
position of EarthLink and MindSpring as of September 30, 1999, assuming that the
proposed reorganization had occurred as of that date. In addition, the unaudited
pro forma condensed combined balance sheet reflects the $200 million investment
of Apple Computer, Inc. in EarthLink's series C convertible preferred stock. The
unaudited pro forma condensed combined statements of operations give effect to
the proposed reorganization by combining the results of operations of EarthLink
for the nine months ended September 30, 1999 and September 30, 1998 and for each
of the three years ended December 31, 1998, with the results of operations of
MindSpring for the same periods, on a pooling of interests basis assuming the
reorganization had occurred on January 1, 1996. In addition, the unaudited pro
forma condensed combined statements of operations reflect acquisitions completed
by EarthLink and MindSpring during 1999 and 1998 as if the acquisitions had been
completed on January 1, 1998. Such information is included herein.

    On June 5, 1998, EarthLink acquired the Sprint Internet Passport business of
Sprint Corporation in a transaction accounted for as a purchase. The unaudited
pro forma condensed combined statement of operations for the year ended
December 31, 1998 is based upon Sprint Internet Passport's historical results of
operations and combines the results of operations as if the transaction with
Sprint had been completed on January 1, 1998.

    On October 15, 1998, MindSpring acquired from America Online various assets
used in connection with the consumer dial-up Internet access business of
Spry, Inc. On February 17, 1999, MindSpring acquired some of the tangible and
intangible assets and rights used in connection with the Internet services
business operated in the United States by NETCOM On-Line Communication
Services, Inc. The unaudited pro forma condensed combined statements of
operations for the year ended December 31, 1998 and the nine months ended
September 30, 1999 reflect these acquisitions by MindSpring as if they had been
completed on January 1, 1998 and for the year ended December 31, 1997 as if the
Spry, Inc. transaction had been completed on January 1, 1997.

    On January 4, 2000, Apple agreed to make a $200 million investment in
EarthLink's series C convertible preferred stock.

    The unaudited pro forma condensed combined financial statements are based on
the estimates and assumptions set forth in the notes to the financial
statements, which are preliminary and have been made solely for purposes of
developing the pro forma information. The unaudited pro forma condensed combined
financial statements are not necessarily an indication of the results that would
have been achieved had the transactions been consummated as of the dates
indicated, or that may be achieved in the future, or the results that would have
been realized had the entities been a single entity during these periods. These
unaudited pro forma condensed combined financial statements should be read
together with the audited historical consolidated financial statements and the
related notes of each of EarthLink, MindSpring, Sprint Internet Passport, Spry
and NETCOM and other financial information pertaining to EarthLink and
MindSpring including under the captions "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Risk Factors" included in
the Securities and Exchange Commission filings of each of EarthLink and
MindSpring, which are included herein.

                            AS OF SEPTEMBER 30, 1999

                                  (UNAUDITED)

NOTES TO WWW HOLDINGS, INC. PRO FORMA CONDENSED COMBINED BALANCE SHEET

1.  This column represents the historical financial position of EarthLink.

2.  This column represents the historical financial position of MindSpring.

3.  This adjustment records the accrual of estimated costs resulting from the
    proposed reorganization. It is anticipated that EarthLink and MindSpring
    will incur charges to operations related to the proposed reorganization,
    which are currently estimated to be $20.5 million, principally in the
    quarter in which the proposed reorganization is consummated. These charges
    include direct transaction costs including estimated investment banking
    fees, financial advisory fees and fees for other professional services.
    These estimated charges are reflected in the unaudited pro forma condensed
    combined balance sheet data, but are not reflected in the unaudited pro
    forma condensed combined statement of operations data. These charges are a
    preliminary estimate only and are subject to change.

4.  Pursuant to the terms of the reorganization agreement, each share of
    EarthLink series A convertible preferred stock, each share of EarthLink
    series B convertible preferred stock and each share of EarthLink series C
    convertible preferred stock will be exchanged for 1.615 shares of newly
    created WWW Holdings series A convertible preferred stock, 1.615 shares of
    newly created WWW Holdings series B convertible preferred stock, and 1.615
    shares of newly created WWW Holdings series C convertible preferred stock
    having terms substantially similar to the EarthLink series A convertible
    preferred stock, the EarthLink series B convertible preferred stock and the
    EarthLink series C convertible preferred stock, as the case may be. This
    adjustment reflects the increase in the aggregate par value of WWW Holdings'
    preferred stock due to the exchange ratio for EarthLink's preferred stock.

5.  Pursuant to the terms of the reorganization agreement, each share of
    EarthLink common stock will be exchanged for 1.615 shares of WWW Holdings
    common stock. This adjustment reflects the increase in the aggregate par
    value of WWW Holdings' common stock due to the exchange ratio for
    EarthLink's common stock.

6.  In 1998 MindSpring's management reviewed its net deferred tax asset,
    consisting primarily of net operating loss carryforwards, and based on the
    net income generated in 1998, as well as the projections of future income,
    determined that it was more likely than not that the deferred tax assets
    would be realized. Accordingly, MindSpring reversed its valuation allowance
    in 1998. In the course of the reorganization discussions, management of
    MindSpring and EarthLink reviewed the combined deferred tax assets and
    concluded that sufficient uncertainty now exists regarding realizability of
    the net deferred tax asset. Accordingly, this adjustment gives the effect to
    the reestablishment of a valuation allowance on the MindSpring net deferred
    tax assets for pro forma purposes.

7.  This adjustment reflects Apple's $200 million investment in EarthLink's
    series C convertible preferred stock.

NOTES TO EARTHLINK NETWORK, INC. PRO FORMA CONDENSED COMBINED STATEMENTS OF
  OPERATIONS

(a) The historical Sprint Internet Passport business revenues and expenses
    include results from January 1, 1998 through June 5, 1998 (the date of
    acquisition).

(b) EarthLink acquired no depreciable assets of the Sprint Internet Passport
    business. This adjustment eliminates the depreciation expense recorded by
    the Sprint International Passport business.

(c) This entry reflects the amortization of intangible assets as follows:
    customer base amortized over 18 months, the Marketing and Distribution
    Agreement amortized over five and ten years, which are the lives of the
    portion of the contract related to Sprint's provision of customers and the
    overall contract period relative to the co-branding feature, respectively,
    and the excess of purchase price over net assets acquired amortized over
    18 months. Additional costs to provide service to the acquired members are
    not considered to be material.

(d) This adjustment reflects the Liquidation Dividends based upon a 3%
    Liquidation Value accretion dividend and the accretion of a dividend related
    to the beneficial conversion feature in accordance with EITF Topic No. D-60
    based upon the rate at which the preferred stock becomes convertible.

(e) Pro forma share data are based on the number of shares of EarthLink's common
    stock and common equivalent shares that would have been outstanding had the
    Sprint International Passport business been acquired on January 1, 1998, but
    excludes any shares purchased by Sprint in the tender offer. EarthLink's
    common stock equivalents have been excluded from the calculation as their
    effect is antidilutive.

    administrative costs that would have been incurred by MindSpring in relation
    to the same assets. In connection with MindSpring's acquisition of the
    NETCOM Domestic Operations, MindSpring and NETCOM (which has changed its
    name to ICG Netahead) have entered into a network services agreement for one
    year with an option for a second year on potentially different terms to be
    negotiated and agreed to by the parties. MindSpring expects to use the
    network services purchased under this agreement initially to provide service
    to the subscribers acquired from NETCOM. MindSpring expects that the costs
    it incurs for such network services will be different than the corresponding
    historical costs reported by NETCOM. In this regard, cost of revenue and
    selling, general and administrative costs incurred by MindSpring in future
    periods may be materially different from the amounts reflected in the pro
    forma financial statements.

(b) Represents additional amortization of the acquired subscriber base based on
    preliminary purchase price allocation for the NETCOM Domestic Operations
    (for both the nine months ended September 30, 1999 and 1998 and the year
    ended December 31, 1998) and the acquisition of certain Spry assets (for the
    nine months ended September 30, 1998 and the year ended December 31, 1998),

                          INFORMATION ABOUT EARTHLINK

BUSINESS

OVERVIEW

    EarthLink is a leading Internet service provider, or ISP, providing reliable
nationwide Internet access and related value-added services to our individual
and business members. Our member base grew from approximately 420,000 members on
December 31, 1997 to approximately 1,556,000 paying members on September 30,
1999, making us one of the world's leading ISPs. We believe our growth has
resulted from our efforts to enhance our members' Internet experience through
simple, rapid and reliable access to the Internet, high quality service, and
member education and support. As a result, we believe we have a high member
retention rate for our industry. We receive significant benefits from the size
of our member base, including bargaining power with content providers, online
advertisers and retailers, and network providers.


    We generate our members through a combination of innovative and
cost-conscious marketing programs. We market our services and products through
referrals, online advertising and magazine, radio and television advertisements.
Our affinity marketing and membership referral programs are also valuable
components of our marketing strategy. We have over 500 affinity marketing
partners, including prominent retailers, print publishers, and software and
hardware companies. Leading affinity marketing partners include Novus Service's
Discover Card, MacMillan Digital Publishing, USAA, SAM's Club, Sony
Entertainment and Warner Bros.



    In June 1998, we entered into a strategic alliance with Sprint, which is
another important driver of our member growth. As a part of this alliance,
Sprint transferred approximately 130,000 members to us and is committed to
generating at least 150,000 new members for us during each of the next 5 years
through their channels. Additionally, we are now co-branded as Sprint's
exclusive consumer Internet access provider, and we have exclusive access to
certain dial-up modem ports in Sprint's network. We also have access to Sprint's
marketing and distribution channels and the right to use Sprint's widely
recognized brand name. As a result of this relationship, we recently added
Sprint PCS and USAA as affinity partners.


    In January 2000, we entered into a strategic alliance with Apple Computer,
which we expect to accelerate our member growth. In connection with this
alliance, we expanded our existing commercial relationship with Apple so that we
shall serve as the default ISP for Apple's Macintosh line of computers for a
minimum of two years and our overall commercial relationship has been extended
through January 4, 2005.

    EarthLink provides highly reliable Internet access through a nationwide
telecommunications network of leased, high-speed, dedicated data lines and over
2,300 dial-up access sites, or POPs. We own and operate POPs in Southern
California and lease POPs from UUNET, Sprint, and PSINet nationwide. Over 90% of
the U.S. population can access our Internet service through a local telephone
call. We also provide Internet connections by cable, ADSL, ISDN, frame relay and
other high-speed access technologies.

    Our standard $19.95 per month dial-up Internet service provides our members
with unlimited access to the Internet, email, a Web browser, six megabytes for a
personal web site, a Personal Start Page, bLink (our member news magazine),
toll-free 24-hour technical support and access to Internet newsgroups. We also
offer premium services to consumers and small businesses, including electronic
commerce solutions, Web hosting and high-speed Internet connections.

    Our address is 3100 New York Drive, Pasadena, California 91107, and our
telephone number is (626) 296-2400.

RECENT DEVELOPMENT--STRATEGIC ALLIANCE WITH APPLE COMPUTER, INC.

    On January 4, 2000, EarthLink and Apple Computer, Inc. entered into a
strategic alliance that expands the two companies' existing relationship. First
announced by Mr. Steve Jobs, Apple's chief executive officer, at the MacWorld
trade show, EarthLink and Apple have enhanced and extended the terms of their
existing commercial relationship and Apple has made a strategic equity
investment in EarthLink.

THE COMMERCIAL AGREEMENT


    Although EarthLink is currently the default ISP in Apple's setup software on
its Macintosh branded line of computers, the new agreement extends the time of
the relationship until January 4, 2005. The new agreement also makes EarthLink
the exclusive default ISP for dial-up, ISDN and DSL services on Macintosh
computers sold in the United States for a minimum of two years during its five
year term. In return for EarthLink being the default ISP in Apple's setup
software on the Macintosh line, EarthLink pays Apple a one-time bounty for each
customer registering through an Apple computing device who meets a minimum
subscription requirement.


    TERMINATION OF EXCLUSIVITY.  Apple has the right to terminate EarthLink's
exclusive default ISP position at any time for the following reasons:

    (a) an uncured breach of the agreement by EarthLink;

    (b) if companies that are engaged in the business of manufacturing,
       marketing, selling or distributing computer hardware or Internet
       connectivity devices, computer operating systems or related products or
       providing Internet access acquire EarthLink stock (or acquire the right
       to purchase EarthLink stock) in connection with an agreement with
       EarthLink, referred to as a Triggering Investment;

    (c) if EarthLink sells or leases all or substantially all of its business or
       assets to a third party, or in the event of a merger or other transaction
       after which EarthLink's stockholders that existed immediately prior to
       the merger or other transaction no longer hold at least 50% of the equity
       in the surviving business (except a transaction with Sprint under the
       EarthLink-Sprint governance agreement) or if an entity (or related
       entities) acquires 50% or more of EarthLink's voting stock as a result of
       a tender offer or other transaction (except a transaction with Sprint
       under the EarthLink-Sprint governance agreement), referred to as an
       EarthLink Change in Control; or

    (d) EarthLink's failure to meet certain service level commitments.

    TERMINATION OF AGREEMENT.  Apple and EarthLink each have the right to
terminate the commercial agreement at any time after January 4, 2002 and for any
uncured breach of the agreement or insolvency of the other party. Apple may also
terminate the agreement upon an EarthLink Change in Control (described above in
item (c)), or if EarthLink sells or leases all or substantially all of its
business or assets to a third party.

    The commercial agreement will be binding on WWW Holdings after the
EarthLink-MindSpring reorganization is completed.

STRATEGIC EQUITY INVESTMENT


    Also on January 4, 2000, Apple agreed to make a $200 million investment in
EarthLink purchasing 4,385,965 shares of a new series C class of EarthLink's
convertible preferred stock for a purchase price of $45.60 per share, which
equaled the 10-day trailing average closing price of a share of EarthLink's
common stock as of January 4, 2000. Apple's investment equals 8.1% of
EarthLink's stock on a fully diluted basis and will equal 4.6% of the stock of
WWW Holdings on a fully diluted basis (in each case assuming that Sprint does
not exercise its rights to maintain its ownership level in EarthLink or WWW
Holdings, as the case may be). The investment closed in escrow on January 5,
2000 pending the


                                       97
<PAGE>

expiration or termination of the waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act. In the event that the waiting period has not expired
or been terminated prior to March 31, 2000, the strategic equity investment may
be unwound. EarthLink intends to use the proceeds of this investment for general
working capital purposes, including marketing, member growth and network and
other systems infrastructure needs.


    Apple also has the following rights:

    VOTING RIGHTS.  The series C convertible preferred stock will be non-voting
during the first year after the closing date of the investment (except for its
right to elect a member to EarthLink's board of directors as discussed below
under "Board Seat" below). After that, it will vote together with the common
stock, and not separately as a class.

    "TOP-UP" RIGHTS.  In the event that Sprint exercises its right to maintain
its ownership level in:

    (a) EarthLink, as a result of Apple's investment, or

    (b) WWW Holdings, Inc. at the same level it had in EarthLink prior to the
       EarthLink-MindSpring reorganization,

    by purchasing additional shares, Apple will have the right to likewise
purchase additional shares of series C convertible preferred stock of WWW
Holdings to maintain its ownership level.

    BOARD SEAT.  Following the expiration or early termination of any applicable
waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act, Apple
has the right to name a member to EarthLink's board of directors for so long as
EarthLink is Apple's exclusive default ISP in the setup software under the
commercial agreement, Apple holds series C convertible preferred stock and Apple
maintains a certain percentage ownership of the EarthLink securities it
purchased in the initial investment and subsequent top-ups. The required
ownership percentages are as follows:

    (a) during the first year after the investment, Apple must maintain
       ownership of 100% of the EarthLink securities it purchased;

    (b) during the second and third years after the investment, Apple must
       maintain ownership of at least 75% of the EarthLink securities it
       purchased; and

    (c) from the fourth year on, Apple must maintain ownership of at least 50%
       of the EarthLink securities it purchased.

    CONVERSION INTO COMMON STOCK.  Each holder of the series C convertible
preferred stock will have the right, following the first year after the
investment, to convert its series C convertible preferred stock into shares of
EarthLink common stock. All shares of the series C convertible preferred stock
will automatically convert into shares of EarthLink common stock for the
following reasons:

    (a) following the first year after the investment if the holders of more
       than 66 2/3% of the series C preferred stock vote to convert all of the
       series C convertible preferred stock into common stock; or

    (b) if conversion is required to consummate any merger, reorganization,
       business combination or other extraordinary transaction (other than the
       EarthLink-MindSpring reorganization) approved by EarthLink's board of
       directors.

    After the EarthLink-MindSpring reorganization closes, the series C
convertible preferred stock will convert into series C convertible preferred
stock of WWW Holdings having the same terms as the series C convertible
preferred stock of EarthLink, and all other provisions of the agreements entered
into in connection with the strategic equity investment will be binding on WWW
Holdings.

    STANDSTILL.  Until the earlier of:

    (a) two years from the closing date of the investment;

                                       98
<PAGE>
    (b) the expiration or termination of EarthLink's status as Apple's exclusive
       default ISP under the commercial agreement; or

    (c) certain third party attempts to acquire control of EarthLink,

Apple cannot acquire more then 19.9% of the voting power of EarthLink's
outstanding capital stock, or make or participate in any solicitation of proxies
or consents with respect to EarthLink's outstanding capital stock.

    REGISTRATION RIGHTS.  After one year from the closing date of the
investment, Apple will have certain rights to require EarthLink to register the
shares of common stock issuable upon conversion of the series C preferred stock
for resale to the public under the Securities Act.

    RIGHT TO MAINTAIN.  In the event of a Triggering Investment, Apple is
entitled to purchase up to a number of securities and on similar terms as were
sold in the Triggering Investment transaction.

STRATEGY

    Our objectives are to be the leading nationwide ISP and to provide our
members with a high-quality Internet experience. Key elements of our strategy
include:

    MAXIMIZE MEMBERS' OVERALL EXPERIENCE.  We want to provide our members with a
superior online experience. The following points illustrate our efforts to do
so:

    Superior Member Service. We believe that an integral part of the EarthLink
experience is fast, polite, and helpful member service. Accordingly, we invest
significant resources in supporting our members. We view member support as
another opportunity to interface directly with our members to educate them on
how to get the most out of the Internet. We have scaled our highly-trained
member support staff in line with member growth to minimize member hold times
and solve each individual problem in the most expeditious manner. Our member
care center is available seven days a week, 24 hours a day via a toll free call.

    Reliable Access. We currently use UUNET, PSINet, Sprint and Level 3 as well
as our own facilities, to provide nationwide dial-up access and network
telecommunications services. Our members can access our service through over
2,300 POPs. As a result, our members are able to navigate the Internet with few
delays, timeouts and disruptions.


    Easy to Use Solution. Users may encounter numerous difficulties using the
Internet because of its size and complexity. Therefore, we focus significant
resources on retaining members by providing them with reliable and easy to use
Internet access. We designed our Internet access software (which includes
software and documentation for both Windows and Macintosh users) to make it easy
for members to register and configure their system for Internet access. We
constantly work to develop new services, content and features to enhance that
user experience.


    Personal Start Page. We provide a customizable personal start page user
interface that allows members to closely match their needs. Members may select
from a number of browsers, navigation engines and sources of news headlines.

    Member sign-up. From marketing and promotional materials to registration and
access software, we have carefully crafted the sign-up process to be easy-to-use
and to engender loyalty.

    Broad Service Offering. Our members receive six megabytes of space on our
Web server and special tools to create their own Web page. We recently
introduced a "Click-N-Build" Web construction tool, an e-commerce solution and
cable access. Going forward, we will continue to offer our members leading
Internet and communication products and services.

    RAPIDLY EXPAND OUR MEMBER BASE.  We believe that a key to our success in the
competitive ISP market is to rapidly expand our member base. This will allow us
to amortize our assets over a larger revenue base and enhance our ability to
enter into favorable arrangements with network service

                                       99
<PAGE>
providers, affinity marketing partners, online advertisers and content
providers. We have accelerated efforts and financial commitments to attract new
members, while continuing to provide high-quality service to ensure member
retention. Historically, we have capitalized on our reputation for high-quality
service and have obtained a significant portion of our new members from existing
member referrals. We have over 500 affinity partners plus numerous other channel
partners. We plan to continue to expand our marketing program, to maintain a
presence at national, regional and local trade shows, and to offer economic
incentives to members who refer new members. Our access to Sprint's high-speed
data network and marketing channels further enhances our ability to add new
members.


    CAPITALIZE ON SPRINT AND APPLE ALLIANCES.  We intend to continue to maximize
the opportunities presented by our alliances with Sprint and Apple to attract
new members nationwide and to further enhance our position as a leading ISP. We
believe that the substantial increase in members and other financial and
operational resources resulting from the Sprint alliance will enable us to
achieve our strategic objectives on a cost-effective and accelerated basis. We
also believe that new members will be generated by the Sprint relationship at a
lower cost than we would spend to add these members on our own. Therefore, we
intend to take full advantage of Sprint's recognized brand image, extensive
distribution channels (including USAA and Sprint PCS) and approximately
16 million long-distance and local telephone customers. To that end, our brand
is jointly marketed with Sprint's widely-recognized brand in connection with
consumer Internet services. Additionally, we expect to further benefit from our
exclusive access to certain dial-up modem ports in Sprint's high-speed data
network.


    INCREASE MARKETING AND EXPAND DISTRIBUTION.  We continue to expand our
targeted marketing programs and distribution efforts to increase our member
base, nationwide presence and brand recognition. To achieve these objectives, we
continue to increase our investments in a wide-ranging marketing and
distribution program, including expanded affinity partners, print publications,
radio, television, billboards and direct mail. We closely monitor the results of
these marketing programs as part of our ongoing effort to increase the
cost-effectiveness of our marketing efforts.

    LEVERAGE THIRD PARTY SERVICE PROVIDERS.  We leverage the infrastructure of
others by leasing POP capacity from UUNET, PSINet, Sprint and Level 3. This
allows us to maintain focus on our members' needs while benefiting from the
continuing decrease in telecommunications services costs. Not only does this
approach lower our required capital expenditures, it also gives us flexibility
to rapidly expand service coverage. Moreover, access to multiple networks
provides members with increased service quality resulting from redundant network
access. We will continue pursuing this strategy so that we can devote our
principal resources to sales and marketing efforts and to improving members'
Internet experience.

    DERIVE INCREMENTAL REVENUES.  We leverage our growing member base and user
traffic to increase revenues from sources other than those that are access
related such as advertising and electronic commerce. Our Premiere Partnership
Program is the principal component of this strategy. Through the Premiere
Partnership Program we sell promotional packages that provide advertisers,
retailers and content providers with access to the multiple points of contact we
have with our members. We also sell advertising space on our various online
properties like the Personal Start Page and our news magazine, bLink. The
EarthLink Mall and branded Personal Start Pages are further sources of
incremental revenues.

    MANAGE INFRASTRUCTURE TO MEET MEMBER GROWTH.  Our membership has grown
rapidly since inception. To continue to effectively add new members and continue
to offer high-quality service, we have made significant capital investments,
including expansion of our network hub, accounting and billing systems and
customer care systems. We believe our current infrastructure is adequate to
manage a significant increase in our member base.

                                      103
<PAGE>
    DIGITAL SUBSCRIBER LINE (DSL).  We recently introduced our DSL services in
numerous markets. Our DSL access service provides up to 100 times faster access
speeds than with a standard modem. The advantages of DSL go beyond speed as DSL
offers a virtually instantaneous connection, with no lengthy dial-in process,
that allows members to use the phone while surfing the Net at the same time. We
charge members $49.95 per month for DSL services. Telephone carriers may charge
equipment and set-up fees in some areas.

    EARTHLINK'S EMERGING ACCESS SERVICES.  In response to feedback from our
members, we are developing the next generation of Internet access services
targeted at consumers and small businesses. These services offer access speeds
several times faster than ISDN connections utilizing a variety of emerging
connectivity technologies.

    CABLE.  We currently offer high-speed cable connections to the Internet for
consumers and small businesses in selected service areas, through partnerships
with cable providers such as Charter Communications.

    ADSL.  We are testing Asymetric Digital Subscriber Line, or ADSL, service
that provides a continuous high-speed connection through existing telephone
lines. This service is in the pilot phase and has not yet been priced.

    FIBER TO THE CURB.  We are conducting a technology trial utilizing "fiber to
the curb" technology, an emerging broadband-capable technology alternative to
both twisted pair copper lines and coaxial cable. This service is in the pilot
phase and has not yet been priced.

    SATELLITE/WIRELESS ACCESS.  EarthLink is currently evaluating opportunities
to offer Internet access service delivery through both satellite and
ground-based wireless technologies.

MEMBER AND TECHNICAL SUPPORT

    We believe that reliable member and technical support is critical to
retaining existing members and attracting new members. We currently provide the
following member and technical support services: (i) toll-free, live telephone
assistance available seven days a week, 24 hours a day; (ii) email-based
assistance available seven days a week, 24 hours a day; (iii) help sites and
Internet guide files on the EarthLink Web site; (iv) automated "fax back" and
"fax on demand" assistance; and (v) printed reference material. Additionally, we
provide dedicated support for business members.

    Our call center currently handles an average of over 130,000 member and
technical support calls a week. We also contract with call center services
vendors whose EarthLink-trained employees provide additional technical support
assistance. We believe the centers' technology and systems are scaleable to
accommodate call volume growth. We actively evaluate our call center facilities
in order to deliver more effective and efficient services to our members.

SALES AND MARKETING

    Our sales and marketing efforts consist of the following programs:

    ORIGINAL EQUIPMENT MANUFACTURER CHANNELS.  EarthLink has marketing
arrangements with a number of leading hardware and software manufacturers to
include our TotalAccess software pre-installed on or included with their
products. Our OEM partners include, among numerous others, Apple, Packard Bell
and Gateway.

    AFFINITY MARKETING PROGRAM.  Affinity marketing partners typically bundle
our TotalAccess software with their own goods or services to create a package
that promotes EarthLink to potential members. Our affinity marketing partners
include, among numerous others:

        DISCOVER CARD.  EarthLink and NOVUS Services' Discover Card division
    offer the Discover Connection, an Internet access package, with exclusive
    features and awards for Discover Cardmembers.

                                      104
<PAGE>
        MACMILLAN DIGITAL PUBLISHING USA.  EarthLink is the exclusive national
    Internet access provider included in the Internet Starter Kit CD-Rom which
    MacMillan publishes.


        SAM'S CLUB.  SAM's Club co-brands and co-offers our Internet access
    software through direct mail and catalog promotions to SAM's Club members.



        SONY ENTERTAINMENT.  Sony bundles our Internet access software on its
    enhanced music CDs.


    SPRINT ALLIANCE.  Our alliance with Sprint includes a marketing agreement
and distribution arrangement that provides us access to Sprint's branded
marketing and distribution channels in the United States, the right to use
Sprint's brand for a minimum of ten years and a five-year commitment from Sprint
to deliver a minimum of 150,000 new members annually through Sprint's channels.
Additionally, Sprint promotes EarthLink as Sprint's exclusive consumer Internet
access provider.

    APPLE ALLIANCE.  Although we have been the default ISP in Apple's setup
software on its Macintosh branded line of computers, our new January 5, 2000
Internet services agreement extends the time of our relationship through
January 4, 2005. This new agreement also makes us the exclusive default ISP for
dial-up, ISDN and DSL services on Macintosh computers sold in the United States
for a minimum of two years.

    MEMBER REFERRAL PROGRAM.  We believe that our existing members are among our
most important marketing tools. We currently waive one month of standard access
service fees for each member who refers a new member to our service. These
referrals generate a significant percentage of our new membership.


    ADVERTISING.  We advertise our services in print, electronic and broadcast
media. We also maintain a presence at national trade shows such as Internet
World and MacWorld, as well as numerous local and regional trade shows.
Additionally, we market through computer, Internet and related publications and
bundle our Internet access software with certain of these publications.


    PREMIERE PARTNERSHIPS.  As part of our strategy to generate incremental
revenue through third party electronic commerce, advertising and content, we
leverage our current properties (such as our Web site and Personal Start Page)
through our Premiere Partnership Program. The Premiere Partnership Program
focuses on third parties having a natural affinity to and benefit for our member
base. The program generates revenues through (1) sales of banner and other
online ads; (2) fees generated through revenue sharing arrangements with online
retailers who are accessed through our properties; and, (3) payments for placing
links from our properties to third-party content

TECHNICAL DEVELOPMENT AND SERVICE ENHANCEMENT


    We place significant emphasis on expanding and refining our services to
enhance member Internet experience. Our technical staff is engaged in a variety
of technical development and service enhancement activities and continuously
reviews new third-party software products and technology for potential
incorporation into our systems and services. The redesigned and enhanced version
of EarthLink 5.0 access software, is a recent product of these efforts. The new
version places a premium on ease of use, and incorporates a variety of powerful
features that reduce the number and types of challenges faced by new members
using the Internet for the first time. We also regularly update and expand the
online services provided through the EarthLink Web site, organize Web content
and develop online guides, help screens and other user services and resources.


POPS AND NETWORK INFRASTRUCTURE

    We provide our members with Internet access primarily through third-party
network POPs. Our use of third parties to provide Internet connectivity enables
us to increase port capacity without the significant capital requirements
necessary to build and maintain a network. It also gives us the flexibility

                                      105
<PAGE>
necessary to adapt to changing technology such as cables. Over 90% of the U.S.
population can access our Internet service through a local telephone call.

    Members located in a geographic area not currently serviced by a local POP
can access the Internet through an 800 service. We have invested in measures to
minimize the effects of damage from fire, earthquake, power loss,
telecommunications failure, computer viruses, security breaches and similar
events or backup Internet services or backbone facilities or other redundant
computing or telecommunications facilities. We do not currently maintain
redundant network hub facilities.

COMPETITION

    We operate in the Internet services market, which is extremely competitive.
Our current and prospective competitors include many large companies that have
substantially greater market presence, financial, technical, marketing and other
resources than we have. We compete directly or indirectly with the following
categories of companies:

    - established online services, such as America Online, the Microsoft Network
      and Prodigy;

    - local, regional and national ISPs, such as MindSpring, Rocky Mountain
      Internet and Internet America Inc.;

    - national telecommunications companies, such as AT&T and GTE;


    - regional Bell operating companies, such as BellSouth and SBC
      Communications Corp;



    - "free access" Internet service providers, such as NetZero, Inc.; and


    - online cable services, such as At Home and Roadrunner.

    Our competition is likely to increase. We believe this will probably happen
as large diversified telecommunications and media companies acquire ISPs and as
ISPs consolidate into larger, more competitive companies. Diversified
competitors may bundle other services and products with Internet connectivity
services, potentially placing us at a significant competitive disadvantage. In
addition, competitors may charge less than we do for Internet services, causing
us to reduce (or preventing us from raising) our fees. As a result, our business
may suffer.

PROPRIETARY RIGHTS

    GENERAL.  We rely on a combination of copyright, trademark, patent and trade
secret laws and contractual restrictions to establish and protect our technology
and proprietary rights and information. We require employees and consultants
and, when possible, suppliers and distributors, to sign confidentiality
agreements. However, we cannot assure you that our steps will be sufficient to
prevent misappropriation of our technology and proprietary rights and
information or that our competitors will not independently develop technologies
that are substantially equivalent or superior to ours.

    From time to time, third parties have alleged that certain of our trademarks
infringe their trademarks. None of these claims has had an adverse effect on our
ability to market and sell its services. However, we cannot assure you that
those claims will not have an adverse effect in the future or that others will
not assert infringement claims against us in the future.


    LICENSES.  We have licenses to distribute third-party software incorporated
in our Internet access software. Applications which we license for distribution
include Netscape Communicator (this license automatically renews each December
for additional one-year terms unless either party terminates the license on
120 days notice), Microsoft Internet Explorer (this license expires in
August 1999 and thereafter automatically renews for additional one-year terms,
although either party may terminate the license at any time on 30 days notice),
and MacTCP software from Apple (this license renews each December for additional
one-year terms unless either party terminates the license on twelve-month
notice). The only software in the Internet access package that we developed is
the front-end and installation/registration program. We intend to maintain or
negotiate renewals of existing software


                                      106
<PAGE>

licenses and authorizations. We may also want or need to license other
applications in the future. Our inability to renew existing software licenses or
to license additional applications could have a material adverse effect on us.


EMPLOYEES

    As of September 30, 1999, we employed 2,057 people, including 273 sales and
marketing personnel, 1,632 operations and member and technical support
representatives and 152 administrative personnel. None of our employees are
represented by a labor union, and we have no collective bargaining agreement.

PROPERTIES


    Our current corporate headquarters and call center are located in a 98,000
square-foot facility in Pasadena, California. Base rent is currently $73,000 per
month. We have an option to extend this lease for an additional five years at
the then-prevailing market rate following its expiration in September 2007. Our
data center and primary data hub are housed in an 110,000 square foot facility
adjacent to our headquarters with rent of $92,000 per month, subject to yearly
increases. The lease for this facility expires February 2007, with an option to
extend for an additional ten year term. On November 15th, we signed a lease for
have a additional facility located less than a mile away that will house our
corporate headquarters, including executive, sales and finance staff. It is
projected to be ready for move in on June 1, 2000. This 125,000 square-foot
facility has a current base rent of $80,000-$200,556, based on step increases in
square foot usage over a period from 11/15/99 to 5/14/02 and subject to annual
increases until the year 2007. The lease for this facility expires on
September 30, 2007, with options to extend for an additional ten year term.
Finally, we added our first remote call center in Sacramento on September 1,
1999. This is a 95,000 square-feet facility with a base rent of $147,722, with
rent increases every twenty months. The lease for this space expires on
August 21, 2009, with options to extend for an additional ten year term.


LEGAL PROCEEDINGS

    We are not currently involved in any legal proceedings that we believe could
have, either individually or in the aggregate, a materiel adverse effect on our
business or financial condition. There are proceedings pending before the FCC
that could adversely affect the ISP industry and the means by which ISPs conduct
business and the cost structure for ISP services. The Company is not a party to
these proceedings.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    EarthLink believes its exposure to market rate fluctuations on its
investments is nominal due to the short-term nature of those investments.
EarthLink has no material future earnings or cash flow exposures with respect to
its outstanding capital leases, which are all at fixed rates. At present,
EarthLink has no plans to enter into any hedging arrangements with respect to
potential future borrowings.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

    THE FOLLOWING DISCUSSION OF THE FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF THE COMPANY SHOULD BE READ IN CONJUNCTION WITH THE FINANCIAL
STATEMENTS AND NOTES THERETO INCLUDED ELSEWHERE IN THIS REPORT JOINT PROXY
STATEMENT/PROSPECTUS.

OVERVIEW

    In September 1999 EarthLink and MindSpring agreed to merge into a newly
formed public company, in a transaction to be accounted for as a pooling of
interests, with MindSpring stockholders receiving one share of the new company
stock for each share of MindSpring stock, and EarthLink stockholders receiving
1.615 shares of the new company stock in exchange for each share of EarthLink
stock. The combined company will be known as EarthLink and will trade under the
Nasdaq symbol

                                      109
<PAGE>
"ELNK." Subject to several conditions, including regulatory approvals, approval
by both companies' shareholders, and certain third-party consents, the
transaction is expected to close in the first quarter 2000.

    We are a leading Internet service provider, or ISP, providing reliable
nationwide Internet access and related value-added services to our individual
and business members. Our member base has grown rapidly from approximately
420,000 members on December 31, 1997 to approximately 1.6 million members on
September 30, 1999, making us one of the world's leading ISPs. We believe this
growth is the result of our efforts to enhance our members' Internet experience
through simple, rapid and reliable access to the Internet, high quality service
and member support and enhanced services. As a result of these efforts, we have
been able to limit average monthly cancellations of our service to industry low
rates of 6.1% in 1996, 5.0% in 1997 and 3.6% in 1998.

    We provide our members with a core set of features through our standard
Internet service, which provides unlimited Internet access and several related
services for a $19.95 monthly fee. We also offer a variety of broadband and
premium services to both our individual and business members. Recurring
revenues, which are generally paid for in advance with credit cards, consist of
monthly fees charged to members for Internet access and other ongoing services
including business Web site hosting, national ISDN, LAN ISDN, DSL and frame
relay connections and, in certain areas, cable access. We derive incremental
revenues by leveraging the value of our member base and user traffic through
promotional and content partnerships, online advertising, and electronic
commerce. We recognize access fees and certain incremental revenues ratably over
the period services are provided. Other revenues generally represent
cancellation fees attributable to certain term marketing programs and one-time,
non-refundable set up fees. Other revenues are recorded as earned.

    Cost of recurring revenues principally includes telecommunications costs and
depreciation expense on equipment used in network operations for ongoing member
services. Fees paid to third party providers for dial-up access to their
respective nationwide systems of POPs are included in telecommunications costs.
Cost of other revenues principally includes expenses associated with new member
registration and cost of products sold. Cost of incremental revenues is
immaterial and is included in cost of other revenues.

    We believe that a key to our success in the competitive ISP market is to
rapidly expand our member base. This will allow us to amortize our assets over a
larger revenue base and enhance our ability to enter into favorable arrangements
with network service providers, affinity marketing partners, online advertisers
and content providers. While we have experienced a trend of continuing
improvement in our net loss and earnings before interest, taxes, depreciation
and amortization ("EBITDA") we anticipate investing heavily in obtaining new
members and expect to have negative EBITDA for the foreseeable future.

    EBITDA is not determined in accordance with generally accepted accounting
principles and is not indicative of cash used by operating activities. You
should not consider EBITDA in isolation from, as an alternative to, or more
meaningful than measures of performance determined in accordance with generally
accepted accounting principles.

SPRINT TRANSACTION

    On June 5, 1998, we entered into a very important strategic alliance with
Sprint in the area of consumer Internet access and related services. In
connection with the formation of that relationship, Sprint tendered for and
purchased 2.5 million shares of our common stock for $22.50 per share. At the
close of the tender offer, we issued Sprint approximately 4.1 million shares of
our newly created

                                      110
<PAGE>
series A convertible preferred stock, convertible into approximately
8.2 million shares of our common stock (assuming the acceleration of certain
rights). In return, Sprint:

    (a) transferred approximately 130,000 members to us;

    (b) paid us approximately $24 million in cash; and

    (c) granted us the exclusive right to use certain dial-up modem ports in
       their high-speed data network for four years.

    Additionally, we entered into a five-year marketing and distribution
agreement with Sprint. The following are highlights from that agreement:

    (a) Sprint must deliver a minimum of 150,000 new members per year for five
       years through its own marketing channels;

    (b) we are Sprint's exclusive provider of consumer Internet access services
       for at least ten years; and,

    (c) we can use Sprint's brand and distribution network for at least ten
       years.

    Sprint also provided us with a $50 million line of credit (increasing to
$100 million over three years) in the form of convertible senior debt.

    We also entered into a governance agreement with Sprint. This agreement
establishes certain terms and conditions concerning our corporate governance,
the acquisition and disposition of our equity securities by Sprint (including
certain preemptive rights in favor of Sprint), the rights of Sprint to make
offers to purchase all outstanding shares of our common stock and rights of our
Board of Directors to receive and entertain offers to effect certain business
combinations. EarthLink, and certain of our stockholders, have also entered into
an agreement with Sprint which obligates such stockholders, under certain terms
and conditions, to take action in support of our obligations to Sprint under the
governance agreement.

    Sprint can appoint (1) one person to our Board of Directors so long as
Sprint owns at least 10% of our capital stock on a fully diluted basis, and
(2) an additional person to our Board of Directors so long as Sprint owns at
least 20% of our capital stock on a fully diluted basis.

    As a result of these transactions, Sprint now owns approximately 27% of our
capital stock on a fully diluted basis (this assumes the conversion of Sprint's
convertible preferred stock into common stock and assumes acceleration of
certain dividend rights and the exercise by Sprint of certain preemptive
rights), of which approximately 10% is voting stock. Sprint has the right to
maintain (but not exceed) these ownership levels by purchasing from us
additional common stock equivalent shares, with up to 75% of these common stock
equivalents being in the form of convertible preferred stock.

    The convertible preferred stock owned by Sprint accrues dividends for the
first five years by increasing its liquidation value at a rate of 3% annually.
Thereafter the convertible preferred stock will pay a cash dividend of 3% of the
liquidation value during years six through 20. The cash dividend will increase
to 8% in year 21 and increase to 12% by year 23.

(1) We began reporting incremental revenues in the first quarter of 1998.

(2) Amortization and transaction costs represent $41,238,000 in amortization of
    intangible assets acquired and a one time transaction cost, in June 1998, of
    $1,397,000 resulting from the strategic alliance with Sprint.

(3) Represents the accretion of liquidation dividends on Series A convertible
    preferred stock at 3% compounded quarterly and the accretion of a dividend
    related to the beneficial conversion feature in accordance with EITF D-60.

(4) SFAS No. 128, Earnings per Share ("EPS"), and Staff Accounting Bulletin
    No. 98 require companies, such as EarthLink, that incorporated the SAB 83
    concept of "cheap stock" in determining pre-initial public offering EPS data
    to restate EPS data to conform to SFAS No. 128. Basic EPS now represents the
    weighted average number of shares divided into net income during a given
    period. Potential common stock items, options, warrants or convertible
    instruments are not included in the calculation of EPS due to their
    anti-dilutive effect.

    principles.

Recurring Revenues

    The Company experienced substantial growth in revenues for the three and
nine month periods ended September 30, 1999 as compared to the corresponding
periods of 1998. The increase in recurring revenues of 80% from $46.9 million in
the quarter ended September 30, 1998 to $84.6 million in the quarter ended
September 30, 1999 was primarily due to an increase in the Company's member base
from 815,000 at September 30, 1998 to 1,566,000 at September 30, 1999.

</TABLE>

    The decrease in dial-up set up fees was primarily due to the Company's
willingness to waive set up fees for dial-up members acquired through certain
marketing programs. The Company expects this trend to continue for dial-up set
up fees. The increase in other fees was due to an increase in the number of
premium services sold such as web-site hosting, broadband services and
cancellation fees attributable to certain term marketing programs.

Incremental Revenues

    The Company continued to focus on deriving additional revenue from marketing
activities targeted to its active member base. Incremental revenues increased
131% from $1.3 million to $3.0 million and 161% from $2.8 million to
$7.3 million during the three and nine month periods ended September 30, 1999,
respectively, as compared to the corresponding periods of 1998. The principal
component of the Company's incremental revenue strategy is its Premier
Partnership Program through which the Company offers and sells promotional
packages that provide advertisers with access to the multiple points of contact
EarthLink has with its members. The Company also sells content space and
advertising on its various online properties such as the Personal Start Page and
its bi-monthly print magazine, "bLink".

</TABLE>

    The decrease in the cost of recurring revenues as a percentage of recurring
revenues was primarily due to the Company's ability to negotiate more favorable
contracts with third party access providers and to effectively manage
communications costs per member.

Cost of Other Revenues


    Cost of other revenues decreased 17% during the three months ended
September 30, 1999 as compared to the corresponding period of 1998 due to a
reduction in ISDN equipment sold to members and the price of ISDN service. Cost
of other revenues increased 93% during the nine months ended September 30, 1999
as compared to the corresponding period of 1998 due to increases in royalties
paid to software vendors and the costs of providing electronic commerce.

Sales and Marketing

    Sales and marketing expenses consist primarily of advertising, direct
response mailings, sales compensation, bounties, communications costs related to
trial members, salaries and the cost of promotional material. Sales and
marketing expenses increased 260% from $10.6 million to $38.2 million during the
three month periods ended September 30, 1998 and 1999, respectively, and 200%
from $26.5 million to $79.6 million in the nine months ended September 30, 1999
as compared to the same period in 1998. The increase was primarily due to
management's increased emphasis on organic growth through marketing strategies
including expanding sales and marketing efforts, increased sales commissions and
increased marketing personnel headcount. Sales, marketing and other direct costs
associated with the acquisition of members are generally expensed as incurred.

Operations and Member Support

    Operations and member support expenses consist primarily of costs associated
with technical support and member service, as well as costs associated with
operating the data center and MIS functions to maintain member accounts.
Operations and member support expenses increased 70% from $15.1 million to
$25.7 million during the three month periods ended September 30, 1998 and 1999,
respectively and 97% from $36.2 million to $71.3 million during the nine months
ended September 30, 1998 and 1999, respectively. These increases reflect
(1) the increase in members from 815,000 as of September 30, 1998 to 1,566,000
as of September 30, 1999, (2) the opening of the Company's two Sacramento call
centers in April 1999 and September 1999 and (3) management's focus on retaining
existing members by providing superior service and devoting significant
resources to expanding technical support staff and network operations
capabilities. The number of employees engaged in operations and member support
activities was 1,553 and 1,633 at September 30, 1998 and 1999, respectively.

General and Administrative

    General and administrative expenses consist primarily of costs associated
with the accounting and human resources departments, professional expenses, bad
debt, credit card processing and executive compensation. General and
administrative expenses increased 66% from $5.9 million to $9.8 million during
the three months ended September 30, 1998 and 1999, and 66% from $15.4 million
to $25.5 million in the nine months ended September 30, 1999 as compared to the
same period in 1998. The increase was primarily due to increases in payroll,
depreciation expense and credit card processing fees. The rise in payroll costs
was primarily due to growth in headcount. In October 1998, the Company occupied
an additional 55,000 square feet of its data center facility, and monthly rent
increased from $66,000 to $92,000. The increase in depreciation expense was due
to the acquisition of office equipment and the build-out of leasehold
improvements. The increase in credit card processing fees was due to the
increase in the Company's member base and increases in fees charged by credit
card companies.

Intangible Assets And Amortization And Transaction Costs

    In June 1998, the Company consummated its strategic alliance with Sprint
Corporation (the "Sprint Transaction"). Intangible assets acquired in the Sprint
Transaction are valued as follows:

    The assets are being amortized on a straight-line basis over the estimated
useful lives as follows: member base amortized over 18 months, the Marketing and
Distribution Agreement amortized over 5 and 10 years, which are the life of the
portion of the contract related to Sprint's provision of additional customers
and the overall contract life relative to the co-branding feature, respectively,
and the excess of consideration over the fair value of net assets acquired
(goodwill) over 18 months. As such, the member base and goodwill will be fully
amortized by December 31, 1999.

    In addition, a non-recurring Sprint Transaction cost of $1,397,000 was
recorded in June 1998.

Interest Income

    Interest income increased from $1.9 million to $4.4 million and from
$2.6 million to $12.7 million during the three and nine months ended
September 30, 1998 and 1999, respectively. The increases were primarily due to
an increase in average cash balances available for investment.

Interest Expense

    Interest expense decreased from $353,000 to $308,000 and from $1.7 million
to $1.0 million during the three months and nine months ended September 30, 1998
and 1999, respectively. The decreases were primarily due to the aging of capital
lease obligations. As capital lease obligations have aged, a greater portion of
lease payments has been attributed to principal payments rather than interest
expense. Furthermore, management has been able to obtain lower effective
interest rates on new lease obligations.

(1) Amortization and transaction costs represent $41,238,000 in amortization of
    intangible assets acquired and a one time transaction cost, in June 1998, of
    $1,397,000 resulting from the strategic alliance with Sprint.

Recurring Revenues

    We experienced substantial growth in revenues during 1998. The increase in
recurring revenues of 120% from $74.7 million in 1997 to $164.7 million in 1998
was primarily due to an increase in our member base from approximately 420,000
at December 31, 1997 to approximately 1 million at December 31, 1998. In
June 1998 we acquired approximately 130,000 members and gained access to
Sprint's marketing and distribution channels as part of our strategic
relationship with Sprint. In addition to those channels, we aggressively
expanded into the OEM arena by securing relationships with Apple, Packard Bell,
NEC and Comp USA.

    We also added several key affinity marketing partners, Sam's Club, Discover
Card and AAA of Southern California.

</TABLE>

    The decrease in dial-up set up fees is primarily due to our increased
willingness to waive set up fees for dial-up members acquired through certain
marketing programs in response to competitive pressures. We expect this trend to
continue for dial-up set up fees. We have continued to expand our sales of
premium services such as business Web site hosting, national ISDN, LAN ISDN,
frame relay connections and cable connections. Set up fees for these services
are generally not waived, and, as such, one-time fees for the set up of
non-dial-up accounts has increased.

Incremental Revenues

    In the first quarter of 1998 EarthLink began reporting incremental revenues
derived from advertising, content and electronic commerce fees that leverage the
value of our growing member base and user traffic. The principal component of
our strategy is our Premiere Partnership Program, through which we offer and
sell promotional packages that provide advertisers with access to the multiple
points of contact we have with our members. We also sell advertising and content
space on our various online properties, such as the Personal Start Page and the
Mall, and through our news magazine, bLink. We generally charge transaction fees
on electronic commerce activities we facilitate. Incremental revenues were
$4.7 million in 1998.

</TABLE>

    Cost of recurring revenues increased 109% during 1998 as compared 1997,
primarily due to the increase in our member base. The decrease in the cost of
recurring revenues as a percentage of recurring revenues is attributable to:
(a) more effective management of our network, (b) the addition of Sprint to our
family of POP providers, and (c) our increasing ability to negotiate more
favorable commercial arrangements with our telecommunications service providers
as we leverage our growing member base.

</TABLE>

    Cost of other revenues decreased 49% in 1998 as compared to 1997. The
decrease was primarily due to a reduction in royalty expense. The increase in
the remaining components of cost of other revenues is primarily due to the
increase in the rate of member growth during 1998.

Sales and Marketing

    Sales and marketing expenses consist primarily of third-party bounties,
advertising, sales commissions, salaries, referral credits, direct communication
costs associated with trial accounts and the cost of promotional material. Sales
and marketing expenses increased from $26.0 million in 1997 to $42.7 million in
1998. The increase was primarily due to increased third-party bounty payments,
increased emphasis on marketing, including expanded sales and marketing efforts
on a nationwide basis, increased sales commissions and increased marketing
personnel headcount. We do not defer sales, marketing or other direct costs
associated with the acquisition of members. We expense these costs as incurred.

General and Administrative

    General and administrative expenses consist primarily of costs associated
with the accounting and human resources departments, professional expenses,
rent, bad debt and compensation. General and administrative expenses increased
46% from $14.4 million in 1997 to $21.0 million in 1998. The increase was
primarily due to an increase in credit card processing fees and an increase in
bad debt expense. The increase in credit card processing fees was due to the
increase in our member base. As a percentage of total revenues, general and
administrative expenses decreased from 18% in 1997 to 13% in 1998.

Operations and Member Support

    Operations and member support expenses consist primarily of costs associated
with technical support and member service, as well as customer information
systems. Operations and member support expenses increased 76% from
$30.9 million in 1997 to $54.4 million in 1998. However, as a percentage of
total revenues Operations and member support expenses decreased from 38% in 1997
to 31% in 1998. We focus on retaining existing members by providing superior
services and devoting significant resources to expanding technical support staff
and network operations capabilities. We had 565 employees engaged in operations
and member support activities on December 31, 1997 and 998 on December 31, 1998.
We continue to improve member service functions by investing in training
programs, hardware and software.

Interest Expense

    Interest expense decreased from $2.1 million in 1997 to $2.0 million during
1998 due to repayment of approximately $4 million in notes payable, the
conversion of $5 million in debt to equity and a

                                      120
<PAGE>
reduction in interest rates paid to lessors. The above was offset by the
increase in capitalized lease obligations.

Interest Income

    Interest income increased from $637,000 in 1997 to $4.4 million 1998. The
increase was primarily due to an increase in average cash balances available for
investment as a result of our public follow on common stock offering completed
in June 1998.

1997 COMPARED TO 1996

Recurring Revenues

    Recurring revenues increased $47.1 million or 171% from $27.6 million in
1996 to $74.7 million in 1997 due to the significant increase in our member base
during 1997.

    Other revenues increased $607,000 or 11% from 1996 to 1997. Due to
competitive pricing and other pressures, we waived set up fees for dial-up
members acquired through certain marketing partnerships. This caused a decrease
in dial-up set up fees earned during 1997. We expect this trend to continue for
dial-up set up fees. During 1997, we began to aggressively promote Web hosting
and nationwide high speed access services. The decline in dial-up set up fees
was offset by increases in the other set up fees and revenues attributable to
our Web hosting, high speed access services and cost of products sold.

Cost of Recurring Revenues

    Cost of recurring revenues increased from $17.7 million in 1996 to
$36.7 million in 1997 because our member base increased, but decreased from 64%
of recurring revenues in 1996 to 49% of recurring revenues in 1997. The decrease
from 1996 to 1997 was primarily due to our ability to effectively manage
communications costs and economies of scale to reduce per member costs as the
total member base expanded. Until October 1996, we paid UUNET a fixed monthly
fee per member plus a variable amount based on member usage in excess of a
threshold number of hours per month. Our network services agreement with UUNET
was amended as of October 1996 to change the cost basis from per member to peak
port hours. In June 1997, UUNET agreed to waive monthly revenue minimums, excess
hours fees and peak service user targets for the remaining six months of 1997.
In return, EarthLink agreed not to invoke its early termination right prior to
September 1998. If usage becomes more concentrated during peak times, the fees
we pay to UUNET will increase, thereby adversely affecting our operating
margins. Under our agreement with PSINet, we pay PSINet a fixed monthly fee for
each member accessing our services through a PSINet POP.

</TABLE>

    Cost of other revenues decreased $717,000 or 38% from $2.1 million in 1996
to $1.3 million in 1997. The decrease was due to the renewal of various
contracts under more favorable terms.

Sales and Marketing

    Sales and marketing expenses increased $8.6 million or 49% from
$17.4 million in 1996 to $26.0 million 1997. The increase was primarily due to
our emphasis on marketing services, expanding sales and marketing efforts
nationwide, increased sales commissions, marketing personnel headcount,
third-party bounties and referral credits. We do not defer sales, marketing or
other direct costs associated with the acquisition of members; rather, we
expense these costs as they are incurred.

General and Administrative

    General and administrative expenses increased $3.9 million or 37% from
$10.5 million in 1996 to $14.4 million in 1997 due to increases in bad debt,
payroll, rent, depreciation expenses and credit card fees. Bad debt expense was
$2.5 million or 7.5% of total revenues in 1996 due to difficulties in billing
and in disconnecting late-paying members on a timely basis. Bad debt expense was
$3.5 million or 4.3% of total revenues in 1997. Bad debt decreases were due to
our review and elimination of accounts with questionable payment history and the
compression of our collection cycle. The rise in payroll costs was primarily due
to growth in headcount. Personnel engaged in general and administrative
activities increased from 92 to 110 during 1997. Depreciation expense rose
because of the acquisition of office equipment and the build-out of leasehold
improvements. Credit card processing fees increased primarily because our member
base increased.

Operations and Member Support

    Operations and member support expenses increased $15.1 million or 96% from
$15.8 million in 1996 to $30.9 million in 1997 reflecting our efforts to retain
existing members by devoting significant resources to expanding technical
support and network operations capabilities. Employees engaged in operations and
member support activities increased from 401 to 565 during 1997. During 1997, we
created a new call center and invested in training programs and hardware and
software to solve member problems.

Interest Expense

    Interest expense increased from $1.0 million in 1996 to $2.1 million in 1997
primarily due to our increased borrowings and capital lease obligations to
finance our expansion of network infrastructure and capital equipment
acquisitions.

Interest Income

    Interest income increased from $150,000 in 1996 to $637,000 in 1997
primarily because of the increase in average cash balances available for
investment.

LIQUIDITY AND CAPITAL RESOURCES

THREE AND NINE MONTHS ENDED SEPTEMBER 30, 1999

    Cash used by operating activities was $8.7 million and $8.0 million during
the three and nine month periods ended September 30, 1999, respectively. During
the three months ended September 30, 1999, the effect of the Company's net loss
of $31.4 million was offset by non-cash expenses, such as depreciation and
amortization expenses, of $23.1 million. During the nine months ended
September 30, 1999, the Company's net loss of $78.2 million was offset by
non-cash expenses, such as depreciation and amortization expenses of
$68.1 million.

    Cash used in investing activities was $11.7 million and $33.7 million during
the three and nine month periods ended September 30, 1999, respectively. Capital
equipment purchases were $11.4 million and $33.6 million during the three and
nine month periods ended September 30, 1999, respectively. Cash proceeds from
sales of capital equipment were $1.2 million and $1.4 million during the three
and nine month periods ended September 30, 1999, respectively. In
September 1999 the Company made an initial investment in a limited partnership
of $1.5 million.

    Cash provided by financing activities was approximately $6.4 million and
$239.2 million during the three and nine month periods ended September 30, 1999,
respectively. Proceeds from the exercise of stock options and warrants were
$6.2 million during the three months ended September 30, 1999. Proceeds and
principal payments under capital leases were $4.0 million and $3.8 million,
respectively, during the three months ended September 30, 1999. Sale leaseback
transactions are recorded at cost, which approximates the fair market value of
the property and, therefore, no gains or losses are recorded. The property
continues to be depreciated by the Company. A financing obligation representing
the proceeds is recorded and reduced based upon payments under the lease
agreement. Proceeds from the exercise of stock options and warrants were
$9.9 million during the nine months ended September 30, 1999. In January 1999,
the Company completed a follow on public offering of 2.4 million shares of its
Common Stock at $73.63 per share. In conjunction with the offering, Sprint
exercised its preemptive rights to maintain its existing ownership level in the
Company. Accordingly, Sprint purchased 808,000 shares of which 201,000 shares
were Common Stock and 607,000 shares were Series B Convertible Preferred Stock
(having the same rights and preferences as the Series A Convertible Preferred
Stock already held by Sprint). Net proceeds from the sale of Common Stock were
$183.1 million. Net proceeds from the sale of Series B Convertible Preferred
Stock to Sprint were approximately $42.6 million. Proceeds and principal
payments under capital leases were $11.8 million and $9.3 million, respectively,
during the nine months ended September 30, 1999.

    As of September 30, 1999, the Company had cash and cash equivalents of
approximately $338.3 million. The Company believes that available cash will be
sufficient to meet the Company's operating expenses and capital requirements for
the next 12 months. EarthLink has available a $50 million credit facility from
Sprint in the form of convertible senior debt, increasing to $100 million by
June 5, 2001, at an interest rate of 6% per annum. The Company's capital
requirements depend on numerous factors, including the rate of market acceptance
of the Company's services, the Company's ability to maintain and expand its
member base, the rate of expansion of the Company's network infrastructure, the
level of resources required to expand the Company's marketing and sales
programs, information systems and research and development activities, the
availability of hardware and software provided by third-party vendors and other
factors.

YEARS ENDED DECEMBER 31, 1996, 1997 AND 1998

    Our operating activities used $16.2 million and $21.3 million in cash during
the years ended December 31, 1996 and 1997, respectively. In all three years,
the Company's net loss was the primary component of cash used in operating
activities. In 1998, however, the Company's net loss was offset by significant
non-cash depreciation and amortization expenses relating to the Company's
network and

                                      123
<PAGE>
intangible assets. Our operating activities provided $26.6 million of cash
during the year ended December 31, 1998, primarily because of the increase in
accounts payable and accrued liabilities of $31.7 million.

    Our investing activities, used cash of approximately $18.4 million,
$16.1 million and $9.2 million in 1996, 1997 and 1998, respectively. Capital
equipment purchases were $18.8 million, $14.5 million and $24.3 million during
the three years then ended. During 1997, we purchased the rights to subscribers
and related assets of Internet in a Mall, Inc., a Tarzana, California based ISP,
at a cost of approximately $1.4 million. Net cash received in the Sprint
transaction of $23.8 million was partially offset by Sprint transaction costs of
$9.9 million for the year ended December 31, 1998.

    Financing activities provided approximately $38.3 million, $49.8 million and
$107.1 million in cash during 1996, 1997 and 1998, respectively. We raised
$8.7 million and $15.4 million in private sales of equity securities during 1996
and 1997, respectively. In the first quarter of 1997, we sold 4.6 million shares
of common stock in our initial public offering and generated approximately
$26.2 million in net proceeds. We completed a follow on public offering in
June 1998 of 3.8 million shares of common stock. Our net proceeds were
approximately $106.3 million. During 1996, 1997 and 1998, we financed the
acquisition of data processing and office equipment amounting to approximately
$11.3 million, $10.5 million and $9.3 million, respectively, through equipment
leases and sale leaseback agreements. We record sale leaseback transactions at
cost, which approximates the fair market value of the property, and, therefore,
no gains or losses are recorded. We continue to depreciate the property and
record a financing obligation representing the proceeds based upon payments
under the lease agreement.

    On December 31, 1998, we had approximately $140.9 million in cash and cash
equivalents. We believe our available cash is sufficient to meet our operating
expenses and capital requirements for the next 12 months. We also have a
$25 million credit facility from Sprint in the form of convertible senior debt,
increasing to $100 million over a three-year period, at an interest rate of 6%
per annum. Our capital requirements depend on numerous factors, including the
rate of market acceptance of our services, our ability to maintain and expand
our member base, the rate of expansion of our network infrastructure, the size
and types of acquisitions in which we may engage and the level of resources
required to expand our marketing and sales programs. We cannot accurately
predict the timing and amount of capital requirements. We may require additional
financing sooner than anticipated if capital requirements vary materially from
those currently planned. We have no commitments for any additional financing
other than the line of credit from Sprint, and we cannot be sure that we can
obtain additional commitments on favorable terms, if at all. Additional equity
financing may dilute our stockholders, and debt financing, if available, may
restrict our ability to declare and pay dividends and raise future capital. If
we are unable to obtain additional needed financing, we may be required to
reduce the scope of operations or anticipated expansion, which could materially
and adversely affect us.

YEAR 2000

    Many existing computer programs use only two digits to identify a year.
These programs were designed and developed without addressing the impact of the
upcoming change in the century. If not corrected, many computer software
applications could fail or create erroneous results by, at or beyond the year
2000. We utilize software, computer technology and other services internally
developed and provided by third-party vendors that may fail due to the year 2000
phenomenon. For example, we are dependent on the institutions involved in
processing our members' credit card payments for Internet services. We are also
dependent on telecommunications vendors and leased dial up access vendors to
maintain network reliability.

    We have completed our assessment of the year 2000 readiness of our
third-party supplied software, computer technology and other services. Based
upon testing and vendor supplied documentation, we

                                      124
<PAGE>
believe that all of our material third party providers are year 2000 compliant
and that all other providers are substantially ready. We tested our own
proprietary software and internal systems and determined them to be year 2000
compliant. We anticipate that our systems, including components thereof provided
by third-party vendors, will operate properly when the year 2000 event occurs.

    The most reasonably likely worst-case year 2000 scenario would be for one or
more of our network service providers to fail thereby making it difficult or
impossible for members to dial-up and access the Internet; however, we maintain
agreements with several nationwide network service providers including UUNET,
Sprint, PSINet and Level 3, and have the ability to switch our members among the
networks of these providers. Therefore, should any of these providers be unable
to provide our members with Internet access as a result of year 2000 problems,
we believe our redundant network arrangements will adequately accommodate our
dial-up access needs. Total costs incurred in connection with our year 2000
readiness efforts have been and are expected to continue to be minimal.

CONVERTIBLE SECURITIES VESTING PLAN

    In December 1997, EarthLink's Board of Directors adopted a plan whereby the
vesting of stock options and warrants held by certain directors and employees
will accelerate upon a change in control of EarthLink. Generally, a change in
control includes the sale of all or substantially all of EarthLink's assets or
the acquisition by a person or group (as that term is defined in Section 13(d)
of the Securities Exchange Act of 1934 and the rules promulgated thereunder) of
25% or more of EarthLink's outstanding voting securities. In connection with the
Sprint Transaction, EarthLink amended this plan so that the Sprint transaction
would not constitute a change in control.

KEY EMPLOYEE COMPENSATION CONTINUATION PLAN

    In January 1998, the EarthLink Board of Directors adopted a plan whereby
those employees identified as "key" or critical are entitled to a severance
payment equal to fifty percent (50%) of their compensation and certain other
benefits received during the twelve-month period ending upon their termination.
EarthLink adopted this plan to attract the highest quality individuals to become
key members of EarthLink's leadership team and to retain the high-quality
individuals who are presently members of its leadership team.

COMPENSATION OF DIRECTORS

    Directors of EarthLink do not receive cash compensation for serving in that
capacity, but are reimbursed for the expenses they incur in attending meetings
of the Board of Directors or any committees thereof. Non-employee directors are
eligible to receive options to purchase EarthLink common stock awarded under its
Directors Stock Option Plan.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    The Compensation Committee of the EarthLink's Board of Directors currently
consists of Messrs. Lacy, O'Donnell and Slatkin. No member of the Compensation
Committee was, during the last fiscal year, an officer or employee of EarthLink
nor was formerly an officer of EarthLink. Members of

                                      127
<PAGE>
the Compensation Committee did not have disclosable relationships with EarthLink
in 1998. However, the following disclosure regarding non-Compensation Committee
Board members is required:

    Mr. Esrey serves as Chairman of the Board of Directors and Chief Executive
Officer of Sprint Corporation. Mr. Lauer serves as President of the Consumer
Services Group of Sprint. On June 5, 1998, EarthLink consummated a series of
transactions with Sprint which, among other things, resulted in Sprint
purchasing 2.5 million shares of EarthLink's Common Stock at $22.50 per share in
a tender offer and purchasing approximately 4.1 million shares of the
EarthLink's Series A Convertible Preferred Stock (which are convertible into
8.2 million shares of Common Stock), in exchange for certain commercial and
financial arrangements. Under the network services agreement that was
implemented in connection with the Sprint alliance, EarthLink paid Sprint
$3,192,637 during 1998.

    EarthLink believes that the foregoing transactions were on terms no less
favorable to EarthLink than could be obtained from unaffiliated parties. It is
EarthLink's current policy that all transactions by EarthLink with officers,
directors, more than five percent stockholders and their affiliates will be
entered into only if such transactions are approved by a majority of
disinterested independent directors and are on terms such directors believe are
no less favorable to EarthLink than could be obtained from unaffiliated parties.

CERTAIN RELATIONSHIPS AND INSIDER TRANSACTIONS

    EarthLink has adopted a current policy that all transactions by EarthLink
with officers, directors, more than five percent stockholders and their
affiliates will be entered into only if such transactions are approved by a
majority of disinterested independent directors and are on terms such directors
believe are no less favorable to EarthLink than could be obtained from
unaffiliated parties.

                          INFORMATION ABOUT MINDSPRING

BUSINESS

    MindSpring is a leading national Internet service provider, or ISP, which
focuses on serving individuals and small businesses. Its primary service
offerings are dial-up Internet access and business services, which it offers in
various price and usage plans designed to meet the needs of its subscribers.
MindSpring's business services include Web hosting, which entails maintaining a
customer's Internet Web site; high-speed, dedicated Internet access; Web page
design and domain name registration. Web hosting, MindSpring's principal
business service, complements its Internet access business and is one of the
fastest growing segments of the Internet marketplace.

    MindSpring offers subscribers complete Internet access and Web hosting
solutions, placing an emphasis on user-friendly and easy to install software,
network reliability, highly responsive customer service and superior technical
support. Through its nationwide network of MindSpring-owned and third-party
provider-owned points of presence, or POPs, MindSpring's subscribers are able to
access the Internet in the 48 contiguous U.S. states and the District of
Columbia via a local telephone call.

    Over the past five years, MindSpring has rapidly increased its subscriber
base and revenues by:

    - providing superior customer service and technical support;

    - expanding its marketing and distribution activities;

    - making strategic acquisitions; and

    - creating additional revenue streams by offering value-added services, such
      as Web hosting, that build on its basic operating capabilities and
      services.

    MindSpring's subscriber base has grown from approximately 12,000 subscribers
at December 31, 1995, to approximately 1.3 million subscribers at September 30,
1999, including approximately 61,000 Web hosting subscribers and approximately
3,000 dedicated Internet access accounts.

    MindSpring was incorporated in Georgia in February 1994, and was
reincorporated in Delaware in December 1995. MindSpring's executive offices are
located at 1430 West Peachtree St., Suite 400, Atlanta, Georgia 30309 and its
telephone number at that address is (404) 815-0770. MindSpring also maintains an
Internet site on the World Wide Web at WWW.MINDSPRING.COM. Information on
MindSpring's Web site is not, and should not be deemed to be, a part of this
joint proxy statement/ prospectus.

RECENT ACQUISITIONS

    In October 1998, MindSpring purchased substantially all of Spry, Inc.'s
subscriber base of individual dial-up Internet access customers in the United
States and Canada, including approximately 130,000 individual access accounts.
MindSpring also acquired various assets used in serving those customers,
including a leased customer support facility and a leased network operations
facility in Seattle, Washington and all rights to the "Sprynet" name. Spry was a
wholly-owned subsidiary of America Online, Inc. The purchase price for these
assets was approximately $32 million.

    In February 1999, MindSpring purchased substantially all of NETCOM On-Line
Communication Services, Inc.'s subscriber accounts in the U.S., including
approximately 408,000 individual access accounts, approximately 25,000 dedicated
Internet access accounts and approximately 25,000 Web hosting accounts. NETCOM,
now known as ICG Netahead, Inc., is a wholly owned subsidiary of ICG
Communications, Inc. MindSpring also acquired assets used in serving those
customers, including leased operations facilities in San Jose, California and
Dallas, Texas and ICG Netahead's rights to the "NETCOM" name, except in Canada,
the United Kingdom and Brazil. ICG Netahead retained all of its assets used in
connection with its network operations. Under a separate network services
agreement

                                      129
<PAGE>
with ICG Netahead, MindSpring purchases access to ICG Netahead's network.
MindSpring paid $245 million for the NETCOM assets, consisting of $215 million
in cash and $30 million in MindSpring common stock.

MINDSPRING SERVICES

    MindSpring's services include dial-up Internet access and business services,
which consist of Web hosting and other services such as high-speed dedicated
Internet access for small to medium-sized businesses and Web page design.
MindSpring's primary service offerings, dial-up Internet access and Web hosting,
are offered in various price and usage plans designed to meet the needs of its
customers. MindSpring continuously evaluates the need to add additional product
offerings and modify its service features based upon market demands.

    INTERNET ACCESS

    DIAL-UP INTERNET ACCESS.  MindSpring's primary service offering is dial-up
Internet access. As of September 30, 1999, approximately 87% of MindSpring's
total revenues were attributable to dial-up Internet access. The basic equipment
requirements for an individual dial-up subscriber are a Windows 3.1 or later
operating system or Macintosh computer with at least 8MB of RAM and a modem of
14.4 Kbps speed or faster. The subscriber's MindSpring connection is a direct,
point-to-point protocol, or "PPP," connection to the Internet. A direct PPP
connection enables a subscriber to use any standard Internet capable software
that will run on the subscriber's computer.

    MindSpring currently offers the following five price plans for dial-up
subscription, taking account of demand for both heavy and light Internet usage.
Each plan requires a start-up fee of up to $25 (except for the COMMERCIAL plan,
which has a start-up fee of $50), which is waived in certain instances depending
upon the promotional method by which the subscriber is acquired.

    THE WORKS.  For $26.95 per month, individual subscribers receive unlimited
usage (not intended to be a full-time connection) as well as 10MB of Web space,
a personal Web page editor that permits subscribers to create and upload their
own Web pages, and five mailboxes.

    UNLIMITED ACCESS.  Individual subscribers pay $19.95 per month for unlimited
usage, 5MB of Web space, and three mailboxes. As with the Works Plan, the
subscriber must disconnect when not actively accessing the Internet. The
subscriber is not permitted, for example, to maintain a full-time computer
connection as a World Wide Web server.

    STANDARD.  Subscribers pay $14.95 per month for 20 hours of use and $1 per
hour for each additional hour. Subscribers also receive 5MB of Web space and one
mailbox.

    LIGHT.  Subscribers pay $6.95 per month for 5 hours of use and $2 per hour
for each additional hour. Subscribers also receive 5MB of Web space and one
mailbox.

    COMMERCIAL.  Designed for small businesses, subscribers pay a $50 start-up
fee and $99 per month thereafter in exchange for 160 hours of usage and $.75 for
each additional hour. Subscribers receive 10 mailboxes and are not charged for
simultaneous usage, which would permit several employees to be on-line at once
without paying additional fees.

    Subscribers to each plan can also purchase additional features such as extra
mailboxes for specified fees.

    Substantially all of MindSpring's subscribers are on month-to-month
subscriptions. MindSpring offers a 30-day money-back satisfaction guarantee for
new subscribers. Billing is monthly, with payments made by the majority of
subscribers by a monthly charge to the subscriber's credit card. Payment is made
at the beginning of each billing cycle, although some subscribers are invoiced
(for an

                                      130
<PAGE>
extra charge). Subscribers, as well as MindSpring, may cancel an account at any
time, with the cancellation taking effect as of the first day of the following
billing month.

    A subscriber who is within local dialing range of one of the MindSpring POPs
or a designated third-party provider POP can access the Internet with a local
telephone call. MindSpring also offers access to its services through an "800"
number for an additional charge. All dial-up subscribers can connect to the
MindSpring network, including the third-party provider POPs, via modem at speeds
up to 56 Kbps. In a majority of the cities that MindSpring serves, individual
subscribers, except subscribers to the UNLIMITED ACCESS and COMMERCIAL plans,
can also choose to connect via ISDN at 64 Kbps or 128 Kbps. There is a one-time
extra start-up fee of $25 for ISDN users who subscribe to the STANDARD and LIGHT
plans; otherwise, 64K ISDN pricing is the same as for modem subscribers, and
128K users pay a small surcharge. All dial-up subscribers also have the option
of using MindSpring servers to publish information on the Internet through the
World Wide Web or FTP. MindSpring subscribers may use the space made available
on MindSpring's servers to make World Wide Web pages or computer data files
available to the Internet.

    MindSpring recently introduced high-speed cable modem Internet access on a
limited basis in Montgomery, Alabama, Columbus, Georgia, Augusta, Georgia,
Charleston, South Carolina, and Panama City, Florida. MindSpring provides this
service through an agreement with KNOLOGY Holdings, Inc., an affiliate of ITC
Holding Company, Inc., one of MindSpring's principal stockholders. MindSpring's
ability to expand its geographic offering of this service will depend on
KNOLOGY's enhancement and expansion of its network infrastructure and
MindSpring's access to other third-party cable and broadband networks.

    MindSpring also recently introduced consumer DSL service on a limited basis
to eleven cities nationwide. This service provides MindSpring customers with an
"always on" connection to the Internet that features download speeds of up to
1.5 megabits per second and eliminates the need for a second analog phone line
for a modem since the connection uses the same wires as the member's primary
phone number. With DSL, members can make and receive phone calls or send faxes
while simultaneously maintaining the "always on" connection to the Internet.

    BUSINESS SERVICES

    MindSpring business services, which are provided by the company's MindSpring
Biz division, consist of:

    - Web hosting, the business of maintaining a customer's Internet Web site;

    - high-speed, dedicated Internet access;

    - Web page design;

    - domain name registration; and

    - e-commerce services.

    As of September 30, 1999, business services revenues, which were derived
almost entirely from Web hosting services, accounted for approximately 13% of
MindSpring's total revenues.

    WEB HOSTING.  MindSpring offers Web hosting accounts for companies and other
organizations that wish to create their own World Wide Web sites without
maintaining their own Web servers and high-speed Internet connections. Web
hosting subscribers can use their own domain names in their World Wide Web
addresses. This type of Web hosting is called "virtual hosting." Web hosting
subscribers create their Web sites themselves and then upload the pages to a
MindSpring Web server. MindSpring's Web hosting service features
state-of-the-art Web servers for high speed and reliability, a high-quality
connection to the Internet, specialized customer support, advanced services
features, such

                                      131
<PAGE>
as secure transactions and VRML, or Virtual Reality Markup Language, a feature
used to make Web pages seem three-dimensional, and reporting on site usage.
MindSpring currently offers three price plans for Web hosting subscribers
ranging from $19.95 to $99.95 per month. As of September 30, 1999, MindSpring
had approximately 61,000 Web hosting subscribers.

    WEB PAGE DESIGN.  MindSpring's Web page design services consist of four
standard design packages from which a subscriber can choose or the subscriber
can create a custom Web package from scratch. The subscriber provides the text
for the Web site, and custom design work is available from MindSpring, including
logo design, additional HTML pages, and database integration.

    E-COMMERCE.  MindSpring's e-commerce hosting service enables even
unsophisticated subscribers to set up an Internet storefront in virtually
minutes. MindSpring offers merchants a complete suite of commercial hosting
options including:

    - Web hosting;

    - Web site or Web page design;

    - domain name registration;

    - store front and back office applications;

    - customer-to-merchant e-mail services;

    - search engine registration;

    - encryption security certificates to assure confidentiality of
      transactions; and

    - credit card and on-line payment processing services.

    DEDICATED ACCESS AND DOMAIN REGISTRATION.  MindSpring offers domain
registration services and, in some markets, high-speed dedicated access
connections to the Internet. As of September 30, 1999, MindSpring had
approximately 3,000 dedicated access accounts.

CUSTOMER SERVICE AND TECHNICAL SUPPORT

    MindSpring believes that excellent customer services and technical support
is critical to its success in retaining and attracting new subscribers.
MindSpring currently provides customer service and technical support through its
call centers located in Atlanta, Georgia; Harrisburg, Pennsylvania; Phoenix,
Arizona; Seattle, Washington; San Jose, California; and Dallas, Texas. In 1999,
MindSpring received the highest ranking in overall customer satisfaction among
Internet service providers in the J.D. Power and Associates 1999 National ISP
Online Residential Customer Satisfaction Study.

    MindSpring's customer service staff handles all questions regarding a
subscriber's account and are available from 9 a.m. to 9 p.m. eastern time seven
days a week, except for major holidays. As of September 30, 1999, MindSpring had
approximately 330 customer service employees.

    MindSpring's technical support staff handles questions related to the
provision of its services such as questions regarding installation of
MindSpring's service, connection to its network and use of various software
applications. MindSpring's technical support staff is available 24 hours a day,
seven days a week, except for major holidays. As of September 30, 1999,
MindSpring had approximately 980 technical support employees.

    Subscribers can call any of MindSpring's call center facilities for customer
service and technical support through a local telephone number, for those cities
local to a call center, or a toll-free "800" number. Subscribers can also e-mail
their questions directly to a customer service and technical support address at
MindSpring. In addition, MindSpring maintains MindSpring-specific newsgroups on
the

                                      132
<PAGE>
Internet where subscribers can post requests for help and other subscribers, as
well as MindSpring support personnel, can respond.

SALES AND MARKETING

    MindSpring believes that the market for individual Internet access is
heavily influenced by person-to-person referrals. Accordingly, MindSpring's
marketing efforts have been geared, among other things, toward generating
positive referrals and stimulating subscriber growth and retention by providing
exceptionally high-quality service to its existing subscribers. MindSpring also
offers a $20 credit to existing subscribers each time a new subscriber names the
existing subscriber as the referral source. A significant number of MindSpring's
new subscribers indicate that an existing subscriber referred them.

    MindSpring also engages in targeted marketing and distribution efforts in
markets where there is the opportunity for substantial market penetration.
MindSpring believes that high geographic concentrations of subscribers improve
network economics and reduce subscriber acquisition costs, thereby resulting in
higher margins. While continuing to encourage referrals from existing
subscribers, MindSpring has recently increased its print publication, radio,
television and direct mail advertising in certain targeted major metropolitan
areas throughout the United States in order to achieve greater density in its
subscriber base.

    In addition, MindSpring has pursued nationwide strategic alliances available
to it as a result of its nationwide access and reputation for reliability and
high quality. Such nationwide marketing opportunities may include, among others,
entering into large-scale bundling arrangements with complementary products,
such as computers, software products, multimedia books, and CD-ROM merchandise,
and seeking strategic alliances available with complementary businesses
operating in its service areas, such as Internet-oriented training organizations
and consulting firms, World Wide Web content developers, computer networking
firms, media companies, telecommunications companies, local area network and
World Wide Web consulting companies, and other Internet access companies that
specialize in providing dedicated connections. The nature and terms of these
alliances vary.

    MindSpring intends to continue to expand its marketing and distribution
efforts. MindSpring will continue to closely monitor the results of its
marketing techniques as part of an ongoing effort to increase the
cost-effectiveness of its marketing efforts.

    MindSpring has attempted to maintain a high degree of personal contact with
the communities that it serves, and has a staff of territory managers who are
responsible for generating interest in MindSpring in these communities.
MindSpring marketing personnel spend considerable time meeting with and making
presentations to groups representing potential subscribers, such as computer
user associations, high-technology business associations, and educational
institutions.

    Sales are consummated by MindSpring's telephone sales force, which responds
to incoming subscription inquiries, as well as through an on-line sign-up
procedure. The on-line registration module, which is available in MindSpring's
retail software package, through MindSpring's Web site and through various
Original Equipment Manufacturer, or OEM, arrangements, enables a user to become
a MindSpring subscriber by selecting service plans and billing methods on-line,
without the need to speak to a MindSpring employee.

NETWORK INFRASTRUCTURE

    GEOGRAPHIC COVERAGE.  Through MindSpring's nationwide network of
MindSpring-owned and third-party provider-owned points of presence, or POPs,
MindSpring's subscribers are able to access the Internet in the 48 contiguous
U.S. states and the District of Columbia via a local telephone call. MindSpring
purchases access to third-party provider POPs through network services
agreements with

                                      133
<PAGE>
PSINet, Worldcom Advanced Networks (formerly Gridnet International, L.L.C.), GTE
Internetworking Incorporated (formerly BBN Planet Corporation) and ICG Netahead.

    MindSpring believes that using a combination of MindSpring-owned POPs and
POPs owned by third-party network providers enables it to provide Internet
access services on a nationwide basis while managing the timing and magnitude of
its capital expenditures. MindSpring employs a strategy of leasing POPs from
third-party providers in locations where it is more economical to do so. These
are typically geographic areas where MindSpring has lower market penetration
than areas it serves through MindSpring POPs. MindSpring periodically
reevaluates the economics of this strategy and, if warranted, may install a
MindSpring POP to replace or overlap with a leased POP.

    MINDSPRING POPS.  Each MindSpring POP typically consists of data
communications equipment such as 3Com-Registered Trademark- Total Control modem
chassis, 3Com-Registered Trademark- or Bay Networks switches and Cisco Systems
routers, the majority of which are currently co-located with a local
telecommunications or media company. The 3Com-Registered Trademark- modem
chassis employed by MindSpring support both ISDN and analog terminations.
MindSpring has upgraded all modem chassis to support the new international 56Kb
modem standard, V.90.

    Each MindSpring POP is connected to MindSpring's Atlanta Network Data
Center. These connections consist of either a private line point-to-point
Internet Protocol, or "IP" connection, or a frame relay connection. In addition,
MindSpring uses private peering points to more efficiently manage its network
traffic. A private peering point is a point where MindSpring's network connects
to the network of one of its third-party network providers. This enables
MindSpring to route network traffic along the shortest path feasible.

    MindSpring refers to some of its POPs as "super-POPs." A super-POP is a POP
where MindSpring co-locates its equipment with a competitive local exchange
carrier, or "CLEC". By co-locating with a CLEC, MindSpring is able to aggregate
Internet traffic from multiple local calling areas into a single modem pool via
local telephone numbers. This creates, in effect, a "super-POP," enabling
MindSpring to offer local dial-up access out of a single POP to areas that would
otherwise require co-location sites in each local dial-up area--that is,
multiple POPs--to accomplish the same task. As part of MindSpring's strategy, it
intends to open additional super-POPs where demand and other economic factors
warrant.

    ATLANTA NETWORK HUB.  MindSpring's Atlanta Network Data Center is connected
to Internet backbone providers such as GTE Internetworking via large leased
telecommunications lines called DS-3s. MindSpring's Atlanta Network Data Center
is supported by dual SONET rings provided by BellSouth Corporation and MediaOne.
The Data Center has a back-up generator for emergency use in the event of a
prolonged loss of electric power. In addition to dial-up subscribers, most of
MindSpring's Web hosting and Web-server co-location customers are served from
this location.

    NETWORK OPERATIONS CENTER.  MindSpring maintains a Network Operations Center
at its Atlanta headquarters through which its technical staff monitors network
traffic, service quality, and security, as well as equipment at individual POPs,
to ensure reliable Internet access. The Network Operations Center is staffed
24 hours a day, 7 days a week. MindSpring also monitors network operations
through its facilities in Seattle, Washington and Dallas, Texas. In the future,
MindSpring may use its other call center facilities to supplement or add
redundancy to this network monitoring capability. In addition, MindSpring
continues to invest in improved network monitoring software and hardware
systems.

MINDSPRING SOFTWARE

    An important component of MindSpring's service offering for dial-up
subscribers is the MindSpring starter kit. The starter kit includes the
MindSpring installation program, front-end software and documentation, an
on-line registration module (retail version only), network software that enables

                                      134
<PAGE>
a subscriber to connect to the Internet, and application programs. MindSpring's
subscribers acquired from Spry and NETCOM connect to the Internet using software
that MindSpring acquired in those acquisitions. Those subscribers may switch to
MindSpring software at their option at any time.

    MindSpring's objectives in developing and providing the MindSpring starter
kit are to:

    SIMPLIFY INSTALLATION.  MindSpring's software package automatically
configures all the individual Internet access programs after one-time entry by
the user of a few required fields of information (name, user name, password,
etc.).

    PROVIDE A CONVENIENT AND INTUITIVE STARTING PLACE FOR
SUBSCRIBERS.  MindSpring's front-end software allows subscribers to connect and
disconnect, see any current messages from MindSpring, check their monthly usage,
see if they have any e-mail, and launch any of their Internet application
programs, all from one screen. "Help" files and the accompanying documentation
contain information on troubleshooting and things to do on the Internet. Links
to the most popular content sites are also provided.

    ENHANCE EFFICIENCY OF MINDSPRING'S SUPPORT SERVICES.  High-quality software
with which MindSpring's technical support representatives are familiar makes it
easier for MindSpring to provide fast and efficient customer service and
technical support. Software that is reliable and easy to install and use also
tends to reduce subscriber need for extensive customer service and technical
support services.

    PROVIDE STATE-OF-THE-ART APPLICATIONS.  MindSpring uses existing
applications developed by third parties in its software package. MindSpring
believes that this approach will enable it to include state-of-the-art software
in its package and to keep pace with technology developments by replacing
applications with newer or better programs as they become available without
diverting resources by attempting to develop new applications programs.

SUBSCRIBER APPLICATIONS

    MindSpring subscribers use their accounts for, among other things,
communicating, retrieving information, and publishing information on the
Internet. In surveys of its subscribers, a substantial number of MindSpring's
individual subscribers report that they use their MindSpring accounts for
personal as well as business purposes. The subscriber's MindSpring connection is
a direct PPP connection, enabling subscribers to use any standard
Internet-capable software that will run on their computers. A complete set of
the most popular Internet applications are part of the MindSpring starter kit
software package, including:

    ELECTRONIC MAIL.  E-mail allows subscribers to exchange electronic messages
with anyone else who has an Internet e-mail address. These messages are usually
text only but can also include other kinds of computer files (such as images,
computer programs, or word processing documents), which are sent as attachments.
MindSpring's software package includes the Microsoft Outlook
Express-Registered Trademark- E-mail application.

    THE WORLD WIDE WEB.  The World Wide Web allows a multimedia presentation of
material (i.e., text, graphic, sound, and video). Users can move from one World
Wide Web site to another by clicking on hypertext links and can interact with
the World Wide Web information providers through typed input. The software
programs that allow users to explore the World Wide Web are known as "browsers."
The browser applications currently included in MindSpring's software package is
Microsoft's Internet Explorer.

    NETWORK NEWS.  Network News provides Internet-wide, subject-specific forums
on thousands of different subjects, where users can post information and review
posted information from other users.

                                      135
<PAGE>
    FTP.  File transfer protocol, or FTP, is a standard Internet tool that
allows users to send and retrieve computer files. FTP is often used for
retrieving software from various archive sites on the Internet.

    INTERNET RELAY CHAT.  Internet Relay Chat allows users to participate in
chat sessions, in which typed comments from all participants appear on the
screen, allowing simultaneous multiperson real-time conversations.

    MindSpring has obtained permission and, in certain cases, licenses from each
manufacturer of the software that MindSpring bundles in its front-end software
product for Windows and Macintosh subscribers.

BILLING AND MANAGEMENT INFORMATION SYSTEMS

    A majority of MindSpring's individual subscribers pay their MindSpring fees
automatically by credit card each month. MindSpring generally sends monthly
invoices to commercial accounts with multiple users. Billing calculations and
payment transactions are managed on MindSpring's automated billing system.
MindSpring expects to continue to modify and upgrade its billing system as
needed in order to maintain its ability to bill and collect amounts due and to
be responsive to changes in the market.

PROPRIETARY RIGHTS

    GENERAL.  Although MindSpring believes that its success is more a function
of its technical expertise and customer service than its proprietary rights,
MindSpring's success and ability to compete depends in part upon its technology.
MindSpring relies on a combination of copyright, trademark and trade secret
laws, and contractual restrictions to establish and protect its technology. It
is MindSpring's policy to require employees and consultants and, when possible,
suppliers to execute confidentiality agreements upon the commencement of their
relationships with MindSpring. These agreements provide that confidential
information developed or made known during the course of a relationship with
MindSpring must be kept confidential and not disclosed to third parties except
in specific circumstances. MindSpring cannot provide any assurances that the
steps it has taken will be adequate to prevent misappropriation of its
technology or that its competitors will not independently develop technologies
that are substantially equivalent or superior to its technology.

    LICENSES.  MindSpring has obtained authorization to use the products of each
manufacturer of software that it bundles in its front-end software product for
Windows and Macintosh subscribers. The particular applications included in the
MindSpring starter-kit have, in some cases, been licensed. MindSpring currently
intends to maintain or negotiate renewals of, as the case may be, all existing
software licenses and authorizations as necessary. MindSpring may also want or
need to license other applications in the future. License fees charged to
MindSpring upon enrollment of additional subscribers are included in the cost of
subscriber start-up fees. Other applications included in the MindSpring starter
kit are shareware for which MindSpring has obtained permission to distribute or
which are from the public domain and are freely distributable. MindSpring
developed the front-end software programs in MindSpring's starter kit for
Windows 3.1, Windows 95, and Macintosh. MindSpring has acquired some software,
trademarks and other proprietary technology from Spry and NETCOM which it may
continue to use for acquired subscribers.

COMPETITION

    The markets for the provision of Internet access and business services to
individuals and small businesses are extremely competitive and highly
fragmented. There are no substantial barriers to entry, and MindSpring expects
that competition will continue to intensify. MindSpring may not be able to
compete successfully against current or future competitors, many of whom may
have financial resources greater than MindSpring. Increased competition could
cause MindSpring to increase its selling and

                                      136
<PAGE>
marketing expenses and related subscriber acquisition costs and could also
result in increased subscriber attrition. MindSpring may not be able to offset
the effects of these increased costs through an increase in the number of its
subscribers or higher revenue from enhanced services, and MindSpring may not
have the resources to continue to compete successfully. These developments could
adversely affect MindSpring's business, financial condition and results of
operations.

    COMPETITIVE FACTORS.  MindSpring believes that the primary competitive
factors determining success in the Internet access and business services markets
are a reputation for reliability and service, effective customer support,
pricing, easy-to-use software, and geographic coverage. Other important factors
include the timing of introductions of new products and services and industry
and general economic trends. MindSpring's current and prospective competitors
include many large companies that have substantially greater market presence and
financial, technical, marketing, and other resources. In addition, every local
market that MindSpring has entered or intend to enter is served by multiple
local ISPs.

    MINDSPRING'S COMPETITORS.  MindSpring currently competes or expects to
compete with the following types of companies:

    - established on-line commercial information service providers, such as AOL
      and Microsoft Network;

    - national long-distance carriers, such as AT&T Corp. and MCI
      WorldCom, Inc.;

    - national commercial ISPs such as EarthLink;

    - computer hardware and software and other technology companies, such as IBM
      Corp.;

    - numerous regional and local commercial ISPs which vary widely in quality,
      service offerings, and pricing;

    - national and regional Web hosting companies that focus primarily on
      providing Web hosting services;

    - cable operators and on-line cable services;


    - local telephone companies and regional Bell operating companies;



    - "free access" ISPs, such as NetZero, Inc.; and


    - nonprofit or educational ISPs.

    MindSpring believes that new competitors, including large computer hardware
and software, media, and telecommunications companies, will continue to enter
the Internet access and business services markets. As consumer awareness of the
Internet grows, existing competitors are likely to further increase their
emphasis on their Internet access and business services, resulting in even
greater competition for MindSpring. In addition, telecommunications companies
may be able to offer customers reduced communications costs in connection with
these services, reducing the overall cost of their Internet access and business
services solutions and significantly increasing pricing pressures on MindSpring.
The ability of MindSpring's competitors to acquire other ISPs, to enter into
strategic alliances or joint ventures or to bundle other services and products
with Internet access or Web hosting could also put MindSpring at a significant
competitive disadvantage.

    BROADBAND TECHNOLOGIES.  MindSpring also faces competition from companies
that provide broadband connections to consumers' homes, including local and
long-distance telephone companies, cable television companies, electric utility
companies, and wireless communications companies. These companies may include
Internet access or business services such as Web hosting using broadband
technologies in their basic bundle of services or may offer Internet access or
business services for a

                                      137
<PAGE>
nominal additional charge. Broadband technologies enable consumers to transmit
and receive print, video, voice and data in digital form at significantly faster
access speeds than existing dial-up modems.

    The companies that own these broadband networks could prevent MindSpring
from delivering Internet access through the wire and cable connections that they
own. Cable television companies are not currently required to allow ISPs to
access their broadband facilities and the availability and terms of ISP access
to broadband local telephone company networks are under regulatory review.
MindSpring's ability to compete with telephone and cable television companies
that are able to support broadband transmission, and to provide better Internet
services and products may depend on future governmental action to guarantee open
access to the broadband networks. However, in January 1999, the Federal
Communications Commission, or FCC, declined to take any action to mandate or
otherwise regulate access by ISPs to broadband cable facilities at this time.
Similarly, the FCC is considering proposals that could limit the right of ISPs
to connect with their customers over broadband local telephone lines. In
December, 1999, MindSpring and AT&T submitted a letter to the FCC outlining in
principle AT&T's commitment to allowing non-affiliated ISPs such as MindSpring
to negotiate access to AT&T's cable systems. This letter is non-binding and
would not take effect until expiration of current exclusive contractual
arrangements to which AT&T is a party. Certain local governmental authorities
have required "open access" as a condition of transfer of their local cable
franchises. However, it is unclear whether they will be successful in
establishing their authority to do so and whether and to what extent other local
and state regulatory agencies will take any similar initiatives. In addition to
competing directly in the ISP market, both cable and telephone facilities
operators are also aligning themselves with certain ISPs who would receive
preferential or exclusive use of broadband local connections to end users. If
high-speed, broadband facilities increasingly become the preferred mode by which
customers access the Internet and MindSpring is unable to gain access to these
facilities on reasonable terms, MindSpring's business, financial condition and
results of operations could be materially adversely affected.

    NO INTERNATIONAL OPERATIONS.  MindSpring does not currently compete
internationally, except MindSpring has a small number of Canadian subscribers
obtained in the Spry acquisition. If the ability to provide Internet access
internationally becomes a competitive advantage in the Internet access industry,
MindSpring may be at a competitive disadvantage relative to its competitors.

GOVERNMENT REGULATION

    As an Internet service provider, MindSpring is not currently directly
regulated by the FCC or any other agency, other than regulations applicable to
businesses generally. In a report to Congress adopted on April 10, 1998, the FCC
reaffirmed that Internet service providers should be classified as unregulated
"information service providers" rather than regulated "telecommunications
providers" under the terms of the Telecommunications Act of 1996.

    This finding is important because it means that regulations that apply to
telephone companies and similar carriers do not apply to MindSpring. MindSpring
also is not required to contribute a percentage of its gross revenues to support
"universal service" subsidies for local telephone services and other public
policy objectives, such as enhanced communications systems for schools,
libraries, and some health care providers. The FCC action is also likely to
discourage states from regulating Internet service providers as
telecommunications carriers or imposing similar subsidy obligations.

    Nevertheless, Internet-related regulatory policies are continuing to
develop, and it is possible that MindSpring could be exposed to regulation in
the future. For example, in the same report to Congress, the FCC stated its
intention to consider whether to regulate voice and fax telephony services
provided over the Internet as "telecommunications" even though Internet access
itself would not be regulated. MindSpring cannot predict whether in the future
the FCC will modify its current policies against regulation of ISPs.

                                      138
<PAGE>
    MindSpring also could be affected by any change in the ability of customers
to reach its network through a dial-up telephone call without any additional
charges. This practice has allowed ISPs to offer flat-rate, non-usage sensitive
pricing, and has been an important reason for the growth in Internet use.
Recently, the FCC ruled that connections linking end users to their ISPs are
jurisdictionally interstate rather than local, but the FCC did not subject such
calling to the access charges that apply to traditional telecommunications
companies. Local telephone companies assess access charges to long distance
companies for the use of the local telephone network to originate and terminate
long distance calls, generally on a per-minute basis. MindSpring could be
adversely affected by any regulatory change that would result in application of
access charges to Internet service because this would substantially increase the
cost of using the Internet. However, the FCC Chairman has stated that he opposes
Internet-related access charges, and MindSpring believes that this development
is unlikely, with one possible exception that is not currently relevant to
MindSpring's business. Specifically, there is substantial debate as to whether
carrier access charges, or the universal support obligations discussed above,
should apply to Internet-based telephone services that substitute for
conventional telephony. MindSpring has no current plans to install gateway
equipment and offer telephony, and so MindSpring does not believe it would be
directly affected by these developments were they to occur.

    The law relating to the liability of Internet service providers and on-line
services companies for information carried on, stored on, or disseminated
through their network is unsettled, even with the recent enactment of the
Digital Millennium Copyright Act. While no one has ever filed a claim against
MindSpring relating to information carried on, stored on, or disseminated
through its network, someone may file a claim of that type in the future and may
be successful in imposing liability on MindSpring. If that happens, MindSpring
may have to spend significant amounts of money to defend itself against these
claims and, if MindSpring is not successful in its defense, the amount of
damages that MindSpring will have to pay may be significant. Any costs that
MindSpring incurs as a result of defending these claims or the amount of
liability that MindSpring may suffer if its defense is not successful could
materially adversely affect its business, financial condition and results of
operations.

    If, as the law in this area develops, MindSpring becomes liable for
information carried on, stored on, or disseminated through its network,
MindSpring may decide to take actions to reduce its exposure to this type of
liability. This may require MindSpring to spend significant amounts of money for
new equipment and may also require it to discontinue offering some of its
products or services.

    Due to the increasing popularity and use of the Internet, it is possible
that additional laws and regulations may be adopted with respect to the
Internet, covering issues such as content, privacy, access to some types of
content by minors, pricing, bulk e-mail or "spam," encryption standards,
consumer protection, electronic commerce, taxation, copyright infringement, and
other intellectual property issues. MindSpring cannot predict the impact, if
any, that any future regulatory changes or developments may have on its
business, financial condition, and results of operations. Changes in the
regulatory environment relating to the Internet access industry, including
regulatory changes that directly or indirectly affect telecommunication costs or
increase the likelihood or scope of competition from regional telephone
companies or others, could have a material adverse effect on MindSpring's
business, financial condition and results of operations.

EMPLOYEES

    As of September 30, 1999, MindSpring had approximately 2,050 employees. None
of MindSpring's current employees is represented by a labor organization, and
MindSpring considers its relations with its employees to be good.

                                      139

PROPERTIES

    MindSpring's corporate headquarters are located in Atlanta, Georgia. The
leases for this space expire on March 31, 2001 and July 14, 2002. MindSpring
also leases additional office space in the vicinity of its Atlanta headquarters
in order to meet MindSpring's existing and anticipated space requirements. The
lease for this additional office space expires on March 31, 2002. In December
1999, MindSpring signed a new lease for a new headquarters/call-center in
Atlanta. This new Atlanta lease expires July 31, 2007. MindSpring has the option
to extend this lease for two successive five year terms.

    Equipment for POPs other than the Atlanta POP site is generally co-located
with and in space leased from other companies operating in the area of the
particular POP.

    MindSpring also maintains call center and/or network operations facilities
in the following locations:

    Harrisburg, Pennsylvania--The lease for this facility has been extended
until April 30, 2000. MindSpring has the option to extend this lease for one
additional year. MindSpring is currently negotiating a subsequent lease for a
total of five years on another building.

    Phoenix, Arizona--The lease for this facility expires on October 31, 2004.
MindSpring has the option to extend this lease for two successive five-year
terms.

    Seattle, Washington--The lease for this facility expires on February 29,
2000. MindSpring is currently negotiating with the landlord/owner for a one to
five year extension.

    Bellevue, Washington--The lease for this facility expires on December 31,
2000. MindSpring has the option to extend this lease for one five-year term.

    Dallas, Texas--The lease for this facility expires on September 30, 2004.
MindSpring has the option to extend this lease for one five-year term.

    San Jose, California--The lease for this facility expires on December 1,
2004. MindSpring has the option to extend this lease for two successive
five-year terms.

LEGAL PROCEEDINGS

    Except as described below, MindSpring is not currently involved in any
pending legal proceedings that are likely to have a material impact on
MindSpring.

    MindSpring has been named as a defendant in a suit filed on November 4, 1999
in the Superior Court of Gwinnett County, Georgia, by Neal Horsley, a former
subscriber of MindSpring's Web hosting services. Mr. Horsley alleges that
MindSpring breached its contract with him when it shut down his anti-abortion
website, known as the Nuremburg Files, on February 4, 1999. MindSpring shut the
site down pursuant to its Appropriate Use Policy and Service Agreement with
Mr. Horsley after a federal court in Oregon determined that Mr. Horsley's
website represented a "blatant and illegal communication of true threats to
kill" one or more physicians. Mr. Horsley seeks $107 million in damages for the
various claims he has brought against MindSpring. MindSpring intends to defend
itself vigorously in this matter, and, while it cannot predict the outcome of
this litigation, it is nonetheless optimistic that it will prevail. A previous
suit filed by Mr. Horsley on June 8, 1999 in which he made substantially the
same claims was voluntarily dismissed.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

    MindSpring believes its exposure to market rate fluctuations on its
investments is nominal due to the short-term nature of those investments.
MindSpring has no material future earnings or cash flow exposures with respect
to its outstanding capital leases, which are all at fixed rates. MindSpring has
no material earnings or cash flow exposure with respect to its outstanding
convertible notes, which are all at fixed rates. To the extent MindSpring has
borrowings outstanding under the credit facility, MindSpring will have market
risk relating to those amounts because the interest rates under the credit
facility are variable. At present, MindSpring has no plans to enter into any
hedging arrangements with respect to potential future borrowings.

OVERVIEW

    MindSpring is a leading national Internet service provider, or ISP. On
September 23, 1999, MindSpring announced that it had entered into an Agreement
and Plan of Reorganization, dated September 22, 1999, with EarthLink
Network, Inc. This merger agreement with EarthLink sets forth the terms and
conditions of the proposed merger of MindSpring and EarthLink into a new
company. The merger of MindSpring and EarthLink is structured to be a
stock-for-stock merger of equals. Pursuant to the merger agreement, each share
of common stock of MindSpring will be converted into one share of common stock
of the new company, and each share of common stock of EarthLink will be
converted into 1.615 shares of common stock of the new company. Other
outstanding securities of the two companies will be converted on the same basis.
Upon consummation of the merger, the new company will be renamed
EarthLink, Inc. The parties intend for the merger to be treated as a tax-free
reorganization under Section 368 of the Internal Revenue Code of 1986, as
amended, and as a "pooling-of-interests" for accounting purposes. Subject to
several conditions, including receipt of required regulatory approvals, approval
by both companies' shareholders, and certain third-party consents, the
transaction is expected to close in the first quarter of 2000.

    MindSpring focuses on serving individuals and small businesses. Our
subscribers use their MindSpring accounts to, among other things, communicate,
retrieve information, and publish information on the Internet. Our primary
service offerings are dial-up Internet access and business services which we
offer in various price and usage plans designed to meet the needs of our
subscribers. Our business services include Web hosting, which entails
maintaining a customer's Web site; high-speed,

                                      142

dedicated Internet access; Web page design; and domain name registration. Web
hosting, our principal business service, complements our Internet access
business and is one of the fastest growing segments of the Internet marketplace.

    We offer our subscribers:

    - user-friendly and easy to install software, containing a complete set of
      the most popular Internet applications including electronic mail, World
      Wide Web access, Network News, File Transfer Protocol and Internet Relay
      Chat;

    - highly responsive customer service, and technical support which is
      available 24 hours a day, seven days a week; and

    - a reliable nationwide network that enables subscribers in the 48
      contiguous United States and the District of Columbia to access the
      Internet via a local telephone call.

    Our nationwide network consists of MindSpring-owned points of presence, or
"POPs," and POPs that are owned by other companies with which we have service
agreements. Through these service agreements, we have the flexibility to offer
Internet access in a particular market through a MindSpring-owned POP, a third
party network provider's POP or a combination of the two. As part of our efforts
to control quality and cost, we typically seek to increase the number of
MindSpring-owned POPs in markets where we have higher numbers of subscribers.

    MindSpring has grown rapidly by:

    - providing superior customer service and technical support;

    - expanding marketing and distribution activities;

    - making strategic acquisitions; and

    - creating additional revenue streams by offering value-added services such
      as Web hosting that build on our basic operating capabilities and
      services.

    We have increased our subscriber base from approximately 12,000 subscribers
at December 31, 1995 to approximately 1,297,000 subscribers at September 30,
1999, including approximately 61,000 Web hosting subscribers and approximately
3,000 Dedicated Internet access subscribers. In addition, by providing superior
customer service and technical support, we have been successful in limiting our
average monthly subscriber cancellation percentage, calculated as the number of
cancellations in a month divided by the beginning subscriber base for that
month, to 3.8% in 1996 and 1997, 3.3% in 1998 and 5.2% for the nine months ended
September 30, 1999.

    We have also rapidly increased revenues. From our inception in
February 1994 through 1997, we experienced annual net operating losses as a
result of efforts to build our network infrastructure and internal staffing,
develop our systems, and expand into new markets. During 1997, we generated
positive cash flows from operations, with EBITDA of approximately $5 million. We
had our first year of profitability in 1998, with net income of approximately
$8.8 million, excluding a one-time tax benefit of approximately $1.7 million.
Including the one-time tax benefit, our net income for 1998 was approximately
$10.5 million. In the third quarter of 1999, in an effort to continue to build
our subscriber base, we increased our sales and marketing expenditures from
traditional levels. This, along with the amortization charges related to our
acquisitions of subscriber bases in the fourth quarter of 1998 and the first
quarter of 1999, had a direct impact on our EBITDA and net income. For the nine
months ended September 30, 1999, we had revenues of approximately
$235.5 million, EBITDA of approximately $35.8 million, a net loss of
approximately $(21.2) million and net loss per share of $(0.35). Excluding
tax-effected amortization expense related to our acquisitions of subscriber
bases, net income for the nine months ended September 30, 1999 was approximately
$15.6 million. EPS+A for this period was $0.24 per diluted share.

                                      143
<PAGE>
    We expect to continue to focus on increasing our subscriber base. Increases
in our subscriber base will cause our revenues to increase but will also cause
our costs of revenue, selling, general and administrative expenses, capital
expenditures, and depreciation and amortization to increase. Our purchases of
subscriber bases such as the Spry and NETCOM acquisitions, described below,
cause an immediate increase in our amortization expense. We generally amortize
subscriber acquisitions over a three-year period. We expect that annual
amortization expense attributable to these transactions will be between
approximately $85 and $90 million per year through 2001. To the extent we
continue to expand our subscriber base through acquisitions such as the Spry and
NETCOM acquisitions, we will continue to experience increased amortization
expense.

    We plan to continue to increase our subscriber base through other means in
addition to subscriber base acquisitions. In July 1999, we announced an
accelerated organic growth marketing effort in which we would increase our sales
and marketing expenditures in both the fourth quarter of 1999 and the first
quarter of 2000. We stated that we would focus a large portion of the additional
expenditures on a national branding campaign, primarily involving television
advertisements, which began in September 1999. The branding campaign was an
integral part of the accelerated growth initiative. We expected that these
incremental sales and marketing expenditures would result in increased
subscriber growth beginning in the fourth quarter of 1999 and continue into the
first quarter of 2000. Under the proposed merger with EarthLink, the combined
company is expected to conduct business under the EarthLink brand name.
Therefore, we have made adjustments to our existing marketing plans to focus
less on branding initiatives and more on direct subscriber acquisition channels
in the fourth quarter of 1999. Overall, we expect our sales and marketing
expenditures in the fourth quarter of 1999 to be significantly higher than our
historical levels, but less than anticipated in our original announcement of the
accelerated organic growth marketing effort.

    We expect to incur negative EBITDA for the fourth quarter of 1999 and the
first quarter of 2000, primarily as a result of increased sales and marketing
expenditures, and we expect to incur net losses through 2000, primarily as a
result of the amortization expense associated with the Spry and NETCOM
acquisitions and the increased sales and marketing expenditures.

    SPRY AND NETCOM ACQUISITIONS.  On October 15, 1998, we completed our
acquisition of the customer base and certain related assets of Spry, Inc. The
total purchase price for the Spry acquisition was approximately $32 million. On
February 17, 1999, we completed the purchase of certain assets used in
connection with the United States Internet access and web hosting business
operated by NETCOM On-Line Communication Services for approximately
$245 million, consisting of $215 million in cash and $30 million in MindSpring
common stock (752,232 shares, at a price per share of $39.88).

    CREDIT FACILITY.  On February 17, 1999, we entered into a credit agreement
with First Union National Bank and several other lenders. The credit agreement
provides for a $100 million revolving credit facility that may be increased at
our option to $200 million with the approval of First Union and the other
lenders under the credit agreement. The credit facility will mature on
February 17, 2002. The credit facility is to be used to fund working capital and
for general corporate purposes, including permitted acquisitions. Our
obligations under the credit facility are secured by substantially all of
MindSpring's assets. On February 17, 1999, we borrowed approximately
$80 million under the credit facility to finance the NETCOM acquisition. We
repaid all amounts outstanding under the credit facility with a portion of the
net proceeds from our April 1999 offering of 5,520,000 shares of common stock,
and we amended the credit facility to permit the issuance of notes, the payment
of interest thereon, and certain redemptions thereof. For a more detailed
description of our secured credit facility, see our Current Report on form 8-K
filed with the Securities and Exchange Commission on February 25, 1999.

    SECURITIES OFFERINGS DURING 1999.  In March 1999, we filed a universal shelf
registration statement with the Securities and Exchange Commission for the
public offering from time to time of up to

                                      144
<PAGE>
$800 million of debt and equity securities. In April 1999, we completed two
public offerings of securities under this shelf registration statement. We sold
5,520,000 shares of common stock, raising net proceeds of approximately
$263.2 million, out of which we repaid all amounts outstanding under the secured
credit facility. We also sold $179,975,000 aggregate principal amount of 5%
Convertible Subordinated Notes due 2006, raising net proceeds of approximately
$174.1 million. The remaining proceeds from these offerings will be used for
expansion of our business, as additional working capital for general corporate
purposes, and for strategic acquisitions of subscriber accounts and
complementary businesses.

    REVENUES.  MindSpring derives revenue primarily by providing individuals
with dialup access to the Internet. Monthly subscription fees vary by billing
plan. Under MindSpring's current pricing plans, customers have a choice of
several "flat rate" plans (The Works and Unlimited Access, e.g.) and several
"usage sensitive" plans (Standard and Light, e.g.). MindSpring also has a
prepayment plan available to all dial-up subscribers which allows subscribers to
prepay their access fees for either one or two years at a discounted rate. For
the nine months ended September 30, 1999, the average monthly recurring revenue
per dialup subscriber was approximately $20.

    In addition, MindSpring earns revenue by providing Web hosting, full-time
dedicated access connections to the Internet, and other value-added services
such as Web page design and domain registration. MindSpring's Web hosting
services allow a business or individual to post information on the World Wide
Web so that the information is available to anyone who has access to the
Internet. MindSpring currently offers price plans for Web hosting subscribers
ranging from $19.95 to $99.95 per month. MindSpring had approximately 61,000 Web
hosting subscribers as of September 30, 1999. Through our domain registration
services, MindSpring offers subscribers the ability to personalize electronic
mail addresses and URLs (Uniform Resource Locators). The revenue from the
services described in this paragraph have been classified as business services
in MindSpring's statements of operations and in the "Results of Operations"
table shown below.

    COSTS.  MindSpring's costs include (1) costs of revenue that are primarily
related to the number of subscribers; (2) selling, general and administrative
expenses that are associated more generally with operations; and
(3) depreciation and amortization, which are related to the number and amount of
MindSpring-owned POPs and other equipment, and the deferred costs associated
with acquired customer bases.

    Costs of revenue that are primarily related to the number of subscribers
consist primarily of the costs of telecommunications facilities necessary to
provide service to subscribers. Telecommunications facilities costs include
(1) the costs of providing local telephone lines into each MindSpring-owned POP;
(2) costs related to the use of third party networks; and (3) costs associated
with leased lines connecting each MindSpring-owned POP and third party network
to MindSpring's hub and connecting MindSpring's hub to the Internet backbone.

    Selling, general and administrative costs are incurred in the areas of sales
and marketing, customer service and technical support, network operations and
maintenance, engineering, accounting and administration. Selling, general and
administrative costs will increase over time as MindSpring's scope of operations
increases. As noted above, we have significantly increased the level of
marketing activity beginning in the third quarter of 1999 to increase the rate
of subscriber growth. Our new marketing strategy is expected to have a
short-term negative impact on net income. We believe that these increased costs
will result in greater subscriber growth; however, there can be no assurance
that these additional sales and marketing expenditures will result in
significantly greater subscriber growth. MindSpring does not defer any sales or
marketing expenses.

    As MindSpring expands into new markets, both costs of revenue and selling,
general and administrative expenses will increase. To the extent MindSpring
opens MindSpring POPs in new markets, these costs and expenses may also increase
as a percentage of revenue in the short term for

                                      145
<PAGE>
the period immediately after a new MindSpring POP is opened. Many of the fixed
costs of providing service in a new market through a new MindSpring POP are
incurred before significant revenue can be expected from that market. However,
to the extent that we expand into new markets by using third party POPs instead
of opening our own POPs, MindSpring's incremental monthly recurring costs will
consist primarily of the fees to be paid to third parties under network services
agreements. In general, the margins on those subscribers will initially be
higher than if we had opened our own POP in new markets. When a market matures,
if the market is served through purchased, third party network services rather
than MindSpring-owned POPs, costs of revenue as a percentage of revenue will
tend to be higher, and therefore, margins on subscribers will tend to be lower.
This is because the full costs of using third party networks is included in
costs of revenue, as compared to the costs of using MindSpring-owned POPs, a
portion of which is included in depreciation. In addition, in more mature
markets where we have greater concentrations of subscribers, we often can
provide services at a lower cost per subscriber through MindSpring-owned POPs
after the initial period when related expenses are higher. This depends in part
on how much we must pay for local area telecommunications charges and the cost
of available alternative third party providers.

    In connection with the NETCOM acquisition, ICG Netahead retained the network
assets that they formerly used to serve the customers we acquired. We purchase
access to that network under a network services agreement with a term of one
year and an option for a second year on potentially different terms to be agreed
upon by the parties. During the first year of the network services agreement
with ICG Netahead, we will pay for use of ICG Netahead's POPs at rates that are
generally comparable to the costs of using MindSpring POPs.

(1) EBITDA represents operating income (loss) plus depreciation and
    amortization. EBITDA is provided because it is a measure commonly used by
    investors to analyze and compare companies on the basis of operating
    performance. EBITDA is not a measurement of financial performance under
    generally accepted accounting principles and should not be construed as a
    substitute for operating income, net income or cash flows from operating
    activities for purposes of analyzing MindSpring's operating performance,
    financial position and cash flows. EBITDA is not necessarily comparable with
    similarly titled measures for other companies.

NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO NINE MONTHS ENDED
  SEPTEMBER 30, 1998

    REVENUE.  Revenues for the nine months ended September 30, 1999 totaled
approximately $235,468,000 as compared to approximately $75,139,000 for the nine
months ended September 30, 1998. This approximately 213% increase in period
revenues resulted primarily from a 185% increase in total subscribers. The
increase in subscribers is due to the acquisition of the NETCOM subscribers in
February 1999, the acquisition of Spry subscribers in October 1998 and organic
growth. Revenues from dial-up access to the Internet, which include start-up
fees and advertising revenues, represented approximately 84% of total revenue
for the nine months ended September 30, 1999 compared to 86% for the nine months
ended September 30, 1998. Business services revenue, consisting primarily of
Web-hosting and dedicated Internet access, grew to 16% of total revenue for the
nine months ended September 30, 1999 from 14% for the nine months ended
September 30, 1998. This increase in business service revenue as a percentage of
total revenue for the nine months ended September 30, 1999 as compared to the
nine months ended September 30, 1998 can be attributed to the growth in our
business services customer base.

    COSTS OF REVENUES.  For the nine months ended September 30, 1999, cost of
revenues increased to approximately 33% of total revenue, compared to
approximately 30% of total revenue for the nine months ended September 30, 1998.
Cost of revenues increased as a percentage of total revenues as a result of a
greater percentage of our subscribers being served through the use of third
party networks rather than MindSpring POPs due to the Spry and NETCOM
acquisitions. Cost of revenues for subscribers being serviced by MindSpring
POP's does not include depreciation for these POPs and other related equipment.

    SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES.  Selling, general, and
administrative expenses were approximately 52% of revenue for the nine months
ended September 30, 1999, compared to approximately 49% of revenue for the nine
months ended September 30, 1998. This increase was due to sales and marketing
costs increasing to 20% of revenue for the nine months ended September 30, 1999
from 15% for the nine months ended September 30, 1999. Selling costs increased
due primarily to higher advertising expenditures related to MindSpring's
accelerated growth program initiated in September 1999 offset by general and
administrative costs declining to 32% of revenue for the nine months ended
September 30, 1999 from 34% for the nine months ended September 30, 1998.
General and administrative costs decreased due to efficiencies gained primarily
through economies of scale.

    EBITDA MARGIN.  EBITDA margin refers to EBITDA as a percentage of revenues.
EBITDA margin decreased to 15% of revenues for the nine months ended
September 30, 1999 from 21% of revenues for the nine months ended September 30,
1998. This decrease is primarily attributable to the increased sales and
marketing expenditures and to costs of revenue being relatively higher in 1999.

    DEPRECIATION AND AMORTIZATION.  Customer base amortization expense increased
significantly from 5% of revenues for the nine months ended September 30, 1998
to 26% for the nine months ended September 30, 1999 due to the acquisitions of
the Spry and NETCOM customer bases, which are being amortized over three years.
Depreciation expense decreased from 8% of revenues for the nine months ended
September 30, 1998 to 6% of revenues for the nine months ended September 30,
1999 due to a smaller percentage of our subscriber base being served by the
company-owned network.

    INTEREST INCOME, NET.  Interest income (expense), net was approximately
$3,463,000 for the nine months ended September 30, 1999 compared to
approximately $590,000 for the nine months ended September 30, 1998. This
increase in interest income (expense), net for the nine months ended
September 30, 1999 compared to the nine months ended September 30, 1998 was
primarily due to interest income increasing as a result of the increase in cash
available for investment purposes, net of interest expense increasing, resulting
from equity offerings in December 1998 and April 1999 and a convertible debt
offering completed in April 1999. The offerings raised net proceeds of
approximately

                                      148
<PAGE>
$562 million from which we repaid $80 million outstanding under a secured credit
facility. Interest expense includes interest on our 5% Convertible Subordinated
Notes due 2006 and fees related to our unused credit facility as well as
amortization of deferred financing costs incurred in conjunction with both.

    INCOME TAX BENEFIT (PROVISION).  For the nine months ended September 30,
1999, MindSpring recorded an income tax benefit of $13,565,000 for an effective
tax rate of 39%, compared to an income tax provision of $212,000, for an
effective tax rate of 3% for the nine months ended September 30, 1998.

    NET (LOSS) INCOME AND (LOSS) INCOME PER SHARE.  As discussed above, and
primarily as a result of the increase in sales and marketing expenditures and in
acquired customer base amortization, MindSpring had a net loss for the nine
months ended September 30, 1999 of ($21,219,000) or $(0.35) per basic and
diluted share. MindSpring's net income for the nine months ended September 30,
1998 was $6,866,000 or $0.13 per diluted share. Excluding tax-effected customer
based amortization expense, MindSpring recorded earnings of $15,591,000 or $0.24
per diluted share ("EPS+A") for the nine months ended September 30, 1999 and
earnings of $9,030,000 or $0.18 per diluted share for the nine months ended
September 30, 1998.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

    REVENUES.  Revenue for the year ended December 31, 1998 totaled
approximately $114.7 million, as compared to approximately $52.6 million for the
year ended December 31, 1997. This approximately 118% increase in period
revenues resulted primarily from an approximately 150% increase in subscribers.
The greater proportional increase in subscribers was principally due to the
acquisition of Spry subscribers from AOL during the fourth quarter of 1998.
Revenues from dial-up access to the Internet for the year ended December 31,
1998 represented approximately 87% of the revenue, compared to approximately 85%
for the year ended December 31, 1997. Business services revenue decreased as a
percentage of revenue to approximately 13% for the year ended December 31, 1998,
compared to approximately 15% for the year ended December 31, 1997. This
decrease is primarily attributable to the large amount of dial-up customers
added through acquisitions in 1998.

    COST OF REVENUES.  For the year ended December 31, 1998, cost of revenues
decreased to approximately 30% of total revenue, compared to approximately 32%
of total revenue for the year ended December 31, 1997. Cost of revenues also
decreased as a percentage of dial-up access revenue to approximately 34% for the
year ended December 31, 1998 from approximately 38% for the year ended
December 31, 1997. Not taking into account approximately $2 million in discounts
we received in 1998 under our network services agreement with PSINet, Inc., cost
of revenues would have been approximately 34% of total dial-up access revenue.
Not taking into account approximately $2.1 million in discounts we received in
1997 under the network services agreement with PSINet, Inc., cost of
revenues-recurring would have been approximately 43% of total dial-up access
revenue. The discounts earned under the network services agreement with PSINet
ended in October 1998. This decrease of cost of revenues as a percentage of
total revenue and as a percentage of dial-up access revenue resulted primarily
from increased efficiency and reduced network costs associated with MindSpring-
owned POPs.

    SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES.  Selling, general, and
administrative expenses were approximately 50% of revenue for the year ended
December 31, 1998, compared to approximately 59% of revenue for the year ended
December 31, 1997. The decrease in selling, general, and administrative expenses
as a percentage of revenue resulted from economies of scale with respect to
costs such as payroll that do not increase in direct proportion to increases in
revenue and from cost control efforts implemented by MindSpring's management.

                                      149
<PAGE>
    EBITDA MARGIN.  EBITDA margin refers to EBITDA as a percentage of revenues.
EBITDA margin increased to approximately 20% for the year ended December 31,
1998, compared to 9% for the year ended December 31, 1997. The increase is
attributable to the significant revenue growth outpacing the related cost
increases principally as a result of economies of scale related to selling,
general, and administrative expenses as well as efficiencies and economies of
scale associated with MindSpring-owned POPs.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
decreased to approximately 13% of revenues for the year ended December 31, 1998,
compared to approximately 17% of revenues for the year ended December 31, 1997.
Amortization expense declined slightly to 6% of total revenues for the year
ended December 31, 1998, compared to approximately 8% for the year ended
December 31, 1997. Amortization expense resulted solely from acquired subscriber
bases, which are being amortized over three years. Depreciation expense was
approximately 7% of total revenues for the year ended December 31, 1998,
compared to approximately 9% for the year ended December 31, 1997. The decrease
in depreciation expense as a percentage of total revenues resulted from adding
capacity through increased use of network services purchased from third-party
providers, as opposed to increasing capacity by building additional
MindSpring-owned POPs, and from reductions in the cost of new equipment and
improved operating efficiencies within MindSpring's network. MindSpring
anticipates amortization expense to increase as a percentage of revenues as a
result of the Spry and NETCOM acquisitions.

    INTEREST INCOME (EXPENSE).  The following table details the increase in
interest income in 1998 compared to 1997:

</TABLE>

    Interest on capital leases increased for the year ended December 31, 1998,
compared to the year ended December 31, 1997, because MindSpring entered into
several new capital leases for equipment at the end of 1997. Interest income
increased in 1998 due to the increase in outstanding cash balances available for
investment as a result of positive operating cash flows and two public equity
offerings completed during the year. See "--Liquidity and Capital Resources".

    INCOME TAX PROVISION.  For the year ended December 31, 1998 MindSpring
recorded a benefit for income taxes due to a one time benefit taken in the
fourth quarter of the year as a result of the removal of the valuation allowance
associated with MindSpring's deferred tax assets. MindSpring is continually
assessing its income tax situation and management believes that it is "more
likely than not" that the deferred tax assets will be realized in the future. In
the future, MindSpring expects to report taxable earnings, even though we expect
to be incurring net losses at the same time. This is principally due to the
requirement that, for tax purposes, subscriber acquisition costs must be
amortized over 15 years, compared to the three-year period applied for
accounting purposes. For the year ended December 31, 1997, no income tax benefit
was recognized as MindSpring had a net taxable loss for the year.

    NET INCOME (LOSS) AND INCOME (LOSS) PER SHARE.  As a result of the factors
discussed above, MindSpring's net income for the year ended December 31, 1998
was $10.5 million, or $0.21 income per diluted share, compared to a net loss of
$4.1 million, or $0.09 basic and diluted loss per share, for the year ended
December 31, 1997.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

    REVENUES.  Revenues for the year ended December 31, 1997 totaled
approximately $52.6 million, as compared to approximately $18.1 million for the
year ended December 31, 1996. The approximately 190% increase in revenues
resulted primarily from an approximately 129% increase in subscribers. Revenues
increased in a greater proportion than subscribers due to the subscribers
acquired from PSINet Inc. during the fourth quarter of 1996. Revenues from
dial-up access to the Internet for the year ended December 31, 1997 represented
approximately 85% of the revenue, compared to approximately 87% for the year
ended December 31, 1996. Business services revenue increased slightly to
approximately 15% of revenues for the year ended December 31, 1997, compared to
approximately 13% for the year ended December 31, 1996. This increase is
primarily attributable to the increase in the number of MindSpring's Web hosting
customers.

    COST OF REVENUES.  For the year ended December 31, 1997, cost of revenues
decreased to approximately 32% of total revenues, compared to approximately 45%
of total revenues for the year ended December 31, 1996. Cost of revenues also
decreased as a percentage of dial-up access revenue from approximately 52% for
the year ended December 31, 1996 to approximately 38% for the year ended
December 31, 1997. Not taking into account approximately $2.1 million in
discounts we received in 1997 under the PSINet Services Agreement, cost of
revenues would have been approximately 43% of total dial-up revenue for the year
ended December 31, 1997, compared to approximately 52% for the year ended
December 31, 1996. This decrease in cost of revenues as a percentage of total
revenues and as a percentage of dial-up access revenues resulted primarily from
increased efficiency and reduced network costs associated with MindSpring-owned
POPs.

    SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES.  Selling, general, and
administrative expenses were approximately 59% of revenues for the year ended
December 31, 1997, compared to approximately 78% of revenues for the year ended
December 31, 1996. The decrease in selling, general, and administrative expenses
as a percentage of revenues resulted from economies of scale with respect to
costs such as payroll that do not increase in direct proportion to increases in
revenue and to cost control efforts implemented by MindSpring's management.

    EBITDA MARGIN.  EBITDA margin increased to approximately 9% for the year
ended December 31, 1997, compared to (23)% for the year ended December 31, 1996.
The increase is attributable to the significant revenue growth outpacing the
related cost increases principally as a result of economies of scale related to
selling, general, and administrative expenses, as well as efficiencies and
economies of scale associated with MindSpring-owned POPs.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
decreased to approximately 16% of revenues for the year ended December 31, 1997,
compared to approximately 18% of revenues for the year ended December 31, 1996.
Amortization expense remained steady at approximately 8% of revenue for both the
years ended December 31, 1997 and December 31, 1996. Amortization expense
resulted primarily from acquired customer bases which are being amortized over
three years. Depreciation expense was approximately 8% of total revenues for the
year ended December 31, 1997, compared to approximately 10% for the year ended
December 31, 1996. The decrease in depreciation expense as a percentage of total
revenues resulted from adding capacity through increased use of network services
purchased from third-party providers, as opposed to increasing capacity by
building additional MindSpring-owned POPs, and from reductions in cost of new
equipment and improved operating efficiencies within MindSpring's network.

</TABLE>

    Interest on capital leases increased for the year ended December 31, 1997,
compared to the year ended December 31, 1996, because MindSpring entered into
several new capital leases for equipment. Interest income increased in 1997 due
to the increase in outstanding cash balances available for investment as a
result of positive operating cash flows.

    INCOME TAX PROVISION.  For the years ended December 31, 1997 and 1996, no
income tax benefit was recognized because MindSpring had a net taxable loss for
the year.

    NET INCOME (LOSS) AND INCOME (LOSS) PER SHARE.  As a result of the factors
discussed above, MindSpring's net loss for the year ended December 31, 1997 was
$4.1 million, or $(0.09) basic and diluted loss per share, compared to a net
loss of $7.6 million, or $(0.24) basic and diluted loss per share, for the year
ended December 31, 1996.

LIQUIDITY AND CAPITAL RESOURCES

    For the nine months ended September 30, 1999, MindSpring generated net cash
from operations of approximately $54.4 million, compared to $18.3 million for
the nine months ended September 30, 1998, an increase of approximately 197%.
During the first nine months of 1999, we spent a total of approximately
$43.2 million primarily related to purchases of telecommunications equipment
necessary for the provision of service to subscribers. We did not enter into any
capital lease agreements in the first nine months of 1999. On February 17, 1999,
we paid $215 million in cash to ICG in connection with the closing of the NETCOM
acquisition, approximately $80 million of which we borrowed under our
$100 million secured revolving credit facility, which we repaid as discussed
below, and the remainder from our available cash.

    As of September 30, 1999, we had approximately $386.8 million of cash. In
March 1999, we filed a universal shelf registration statement with the
Securities and Exchange Commission for the public offering from time to time of
up to $800 million of debt and equity securities. In April 1999, we completed
two public offerings of securities under this shelf registration statement. We
sold 5,520,000 shares of our common stock raising net proceeds of approximately
$263.2 million, from which we repaid approximately $80 million of principal and
interest outstanding under our secured credit facility. We also sold
$179,975,000 aggregate principal amount of our 5% Convertible Subordinated Notes
due 2006, raising net proceeds of approximately $174.1 million. Net of expenses
and repayment of debt, MindSpring raised an aggregate of approximately
$357.3 million in these offerings.

    MindSpring's future capital requirements depend on various factors
including, without limitation:

    - the rate of market acceptance of MindSpring's services;

    - our ability to maintain and expand our subscriber base;

    - the rate of expansion of MindSpring's network infrastructure;

    - the resources required to expand our marketing and sales efforts; and

    - the availability of hardware and software provided by third party vendors.

                                      152
<PAGE>
    If the merger of MindSpring and EarthLink is consummated, the holders of
MindSpring's 5% Convertible Subordinated Notes due 2006 will have the option to
require the new company to repurchase the notes. Pursuant to the merger
agreement between MindSpring and EarthLink, the repurchase price for the notes
will be paid in cash at a repurchase price of 100% of the principal amount plus
accrued interest to the date of repurchase.

    We currently estimate that our cash and financing needs for the remainder of
1999 and 2000 can be met by cash on hand, amounts available under our credit
facility, additional capital financing arrangements, and cash flow from
operations. If our credit facility is unavailable or if our expectations change
regarding our capital needs due to market conditions, strategic opportunities or
otherwise, then our capital requirements may vary materially from those
currently anticipated. We do not currently have any commitments for any
additional financing, and there can be no assurance that if and when we need
additional capital it will be available on terms that are acceptable to us, if
at all. If additional capital financing arrangements, including public or
private sales of debt or equity securities, or additional borrowings from
commercial banks are insufficient or unavailable, or if we experience shortfalls
in anticipated revenues or increases in anticipated expenses, we will be
required to modify our growth and operating plans to match available funding.
Any additional equity financing may be on terms that are dilutive or potentially
dilutive to MindSpring's stockholders. Debt financing, if available, may involve
restrictive covenants with respect to dividends, raising future capital and
other financial and operational matters and incurring additional debt may
further limit MindSpring's ability to raise additional capital. In addition, our
credit facility contains restrictions on our ability to incur additional debt
and to issue some types of convertible or redeemable capital stock.

    MindSpring frequently engages in discussions involving potential business
combinations. Depending on the circumstances, MindSpring may not disclose
material transactions until completion of a definitive agreement. MindSpring may
determine to raise additional debt or equity capital to finance potential
acquisitions and/or to fund accelerated growth. Any significant acquisitions or
increases in MindSpring's growth rate could materially affect MindSpring's
operating and financial expectations and results, liquidity and capital
resources.

YEAR 2000

    INTRODUCTION.  The term "Year 2000 issue" is a general term used to describe
the various problems that may result from the improper processing of dates and
date-sensitive calculations by computers and other machinery as the year 2000 is
approached and reached. These problems generally arise from the fact that most
of the world's computer hardware and software have historically used only two
digits to identify the year in a date, often meaning that the computer will fail
to distinguish dates in the "2000's" from dates in the "1900's." These problems
may also arise from other sources as well, such as the use of special codes and
conventions in software that make use of the date field.

    STATE OF READINESS.  We have established a Year 2000 program office to
coordinate appropriate activity and report to the Board of Directors on a
continuing basis with regard to the Year 2000 issue. Our Year 2000 program
office has developed and implemented a comprehensive Year 2000 program for us to
become Year 2000 ready. The Year 2000 program consists of six phases:
(1) project planning and inventory of our assets, (2) assessment of remediation
requirements, (3) remediation (whether by upgrade or replacement), (4) testing
and validation of selected critical assets, (5) implementation and (6) creation
of contingency plans in the event of year 2000 failures.

    The Year 2000 program covers the following: (1) internally developed
software products which we provide to our customers, (2) our information
technology systems, (3) our network elements, (4) our operational support
systems, and (5) certain non-information technology systems, including embedded
technology. In addition, the program calls for us to identify and assess the
systems and services of our third party suppliers, such as major vendors, third
party network service providers and other material

                                      153
<PAGE>
service providers, and take appropriate remedial actions and develop contingency
plans where appropriate in connection with such third party suppliers.

    We provide our customers with a software package which, among other things,
allows our customers to access our services. The software package consists of
internally developed software (e.g., the MindSpring Internet software) which is
bundled with third party software. We have conducted operational testing and
believe that the current shipping version of the MindSpring Internet software is
Year 2000 ready. In addition, we have completed the inventory, assessment,
remediation and testing and validation phases of the Year 2000 program. We have
not and do not intend to test our USENET news service which is heavily dependent
on external news feeds.

    We have performed a technical review of many of the more critical third
party systems and have surveyed the publicly available statements issued by the
vendors of those systems, in an effort to assess their Year 2000 readiness
status. Additionally, we have contacted our significant providers of third party
systems requesting information regarding their vulnerability to Year 2000 issues
and whether the products and services purchased from those entities are Year
2000 ready. We are evaluating these responses for their accuracy and adequacy,
and are continuously updating appropriate contingency plans for any material
supplier that does not provide an adequate response.

    We have not deferred any specific information technology project due to the
Year 2000 program. We engaged a consulting firm to assist us in completing the
inventory, assessment and testing phases of our Year 2000 program, and to assist
us in our Year 2000 program management.

    COSTS.  We have incurred expenses of approximately $600,000 in connection
with the implementation of the Year 2000 Program Office and Year 2000 program.
These costs were expensed as incurred. We estimate that we will incur minimal
expenses through the remainder of the Year 2000 program. The costs and estimates
provided include our estimate of the cost of internal resources directly
attributable to the Year 2000 program. We have funded, and anticipate that we
will continue funding, the costs of the Year 2000 program from cash flows. The
estimates for the costs of the Year 2000 program are based upon management's
best estimates and may be updated or revised as additional information becomes
available. We currently believe these costs will not have a material effect on
our financial condition, liquidity or results of operations.

    RISKS.  Our failure to correct a material Year 2000 problem could result in
an interruption in, or a failure of, normal business activities or operations.
Presently, however, we perceive that our most reasonably likely worst case
scenario related to the Year 2000 is associated with potential concerns with
third party services or products.

    Specifically, we are heavily dependent on a significant number of third
party vendors to provide both network services and equipment. A significant Year
2000-related disruption of the network services or equipment provided to us by
third party vendors could cause customers to consider seeking alternate
providers or cause an unmanageable burden on customer service and technical
support, which in turn could materially and adversely affect our results of
operations, liquidity and financial condition. We are not presently aware of any
vendor related Year 2000 issue that is likely to result in this type of
disruption.

    Furthermore, our business depends on the continued operation of, and
widespread access to, the Internet. To the extent that the normal operation of
the Internet is disrupted by the Year 2000 issue, our results of operations,
liquidity and financial condition could be materially and adversely affected.

    CONTINGENCY PLANS.  We developed contingency plans for our primary business
operations. We will continue to monitor our third party suppliers and will
adjust any appropriate contingency plans accordingly.

    The estimates and conclusions included in this discussion contain
forward-looking statements and are based on management's best estimates of
future events. Our expectations about risks, future costs and the timely
completion of its Year 2000 modifications may turn out to be incorrect and any
variance from these expectations could cause actual results to differ materially
from what has been discussed above. Factors that could influence risks, amount
of future costs and the effective timing of remediation efforts include our
success in identifying and correcting potential Year 2000 issues and the ability
of third parties to appropriately address their Year 2000 issues. The foregoing
Year 2000 discussion and the information contained herein is provided as a "Year
2000 Readiness Disclosure" as defined in the Year 2000 Information and Readiness
Disclosure Act of 1998 (Public Law 105-271, 112 Stat. 2386) enacted on
October 19, 1998.

    RECENT ACCOUNTING PRONOUNCEMENTS

    The FASB has issued Statement No 133, Accounting for Derivative Instruments
and Hedging Activities, which must be adopted by the year 2000. In June 1999,
the FASB issued Statement No. 137, Accounting for Derivative Instruments and
Hedging Activities- Amendment of thE Effective Date of FASB No. 133, which
amends Statement No. 133 to be effective for all fiscal quarters and for all
fiscal years beginning after June 15, 2000 (that is, January 1, 2001 for
companies with calendar-year fiscal years). This statement establishes
accounting and reporting standards for derivative instruments-including certain
derivative instruments embedded in other contracts--and for hedging activities.
Adoption of this statement is not expected to have a material impact on
MindSpring's financial statements.

DIRECTOR COMPENSATION

    Since MindSpring's inception, members of its board of directors have not
received any compensation for their service on the board of directors except
pursuant to MindSpring's Directors Stock Option Plan. Under the Directors Plan,
420,000 shares of common stock are authorized for issuance to non-employee
directors, in the form of grants of 60,000 options per director, upon their
initial election or appointment to the board, or, in the case of
Messrs. Lanier, Scott and Gabbard, who joined the board prior to the creation of
the Directors Plan, upon the adoption of the Directors Plan by the board.
Options are exercisable at the fair market value of the common stock, as
determined by the board, on the date of grant. The Directors Plan was amended in
1998 to provide for discretionary option grants. Upon adoption of this
amendment, each of Messrs. Lanier, Scott and Gabbard received a grant of 30,000
options.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    The members of the Compensation Committee for the year ended December 31,
1998 were Messrs. Gabbard, Lanier and Scott.

    ITC Holding Company, Inc. beneficially owned approximately 18.5% of the
outstanding capital stock of MindSpring as of December 31, 1998 and owned
approximately 16.7% of MindSpring as of November 30, 1999. Both Messrs. Lanier
and Scott have served since at least 1998 as executive officers and directors of
ITC Holding. Mr. Gabbard has also served since at least 1998 as a director of
ITC Holding. As of December 31, 1998 and October 5, 1999, Messrs. Lanier, Scott
and Gabbard owned approximately 18%, less than 1.0% and less than 1.0%,
respectively, of the common stock of ITC Holding. As of December 31, 1998 and
October 5, 1999, Mr. Brewer owned less than 1.0% of the common stock of ITC
Holding.

    MindSpring has entered into certain business relationships with subsidiaries
and affiliates of ITC Holding. MindSpring leases T-1 telecommunications lines
for data transport for some of its points of presence and purchases long
distance telephone services, maintenance and installation services and wide area
network transport service from ITC^DeltaCom, which until October 20, 1997 was
owned by ITC Holding and is now owned by substantially the same stockholders as
ITC Holding. MindSpring paid ITC^DeltaCom approximately $254,000 per month in
1998 and approximately $975,000 per month in 1999 for these services.

    MindSpring leases telephone lines from, and has contracts for maintenance
and installation with, Interstate Telephone Company, Inc., a wholly owned
subsidiary of ITC Holding. MindSpring paid Interstate Telephone approximately
$18,000 per month in 1998 and approximately $50,000 per month in 1999 for these
leased telephone lines.

    MindSpring also provides high-speed cable modem Internet access through an
agreement with KNOLOGY Holdings, Inc., an affiliate of ITC Holding. MindSpring
pays KNOLOGY approximately $80,000 per year for these services.

CERTAIN RELATIONSHIPS AND INSIDERS TRANSACTIONS

    MindSpring has adopted a policy requiring that any material transactions
between MindSpring and persons or entities affiliated with officers, directors
or principal stockholders of MindSpring be on terms no less favorable to
MindSpring than reasonably could have been obtained in arms' length transactions
with independent third parties.

    For a summary of certain transactions and relationships among MindSpring and
its associated entities, and among the directors, executive officers and
stockholders of MindSpring and its associated entities, see "--Compensation
Committee Interlocks and Insider Participation."

                         INFORMATION ABOUT WWW HOLDINGS

    WWW Holdings is a newly formed Delaware corporation that has not, to date,
conducted any activities other than those incident to its formation, its
execution of the reorganization agreement and related agreements, and its
participation in the preparation of this joint proxy statement/prospectus. The
financial statements of WWW Holdings are omitted because WWW Holdings has
nominal assets, no liabilities as well as no operations to date. There are also
no contingent assets or liabilities.

                   DESCRIPTION OF WWW HOLDINGS CAPITAL STOCK

GENERAL

    The following is a summary of the characteristics of WWW Holdings' capital
stock.


    Presently the authorized capital stock of WWW Holdings consists of 10,000
shares of WWW Holdings common stock. There are 10 shares of WWW Holdings common
stock outstanding, all of which are owned by the incorporator of WWW Holdings.
These shares will be canceled in the merger of EarthLink into WWW Holdings. No
shares of WWW Holdings preferred stock are outstanding. At or before the
effective time of the merger of EarthLink into WWW Holdings, WWW Holdings will
amend and restate its certificate of incorporation, which amendment and
restatement will, among other things, authorize 300 million shares of common
stock and 100 million shares of preferred stock. The description below assumes
that the certificate of incorporation has been amended and restated.


    Based on December 20, 1999 data and assuming that Apple's $200 million
investment in EarthLink had occurred on December 20, 1999, immediately following
the effective time of the mergers of EarthLink and MindSpring into WWW Holdings,
former holders of EarthLink common stock and EarthLink preferred stock
collectively will hold approximately 53.3% of the outstanding shares of WWW
Holdings common stock on a fully diluted basis; and former holders of MindSpring
common stock collectively will hold approximately 46.7% of the outstanding
shares of WWW Holdings common stock on a fully diluted basis.

COMMON STOCK

    Each share of WWW Holdings common stock entitles its holder to one vote on
all matters required or permitted to be voted on by WWW Holdings. The terms of
the WWW Holdings common stock do not contain any conversion or redemption rights
or rights to subscribe for more securities of WWW Holdings. Holders of WWW
Holdings common stock have no right to cumulate votes in the election of
directors. Holders of WWW Holdings common stock are entitled to receive
dividends if declared by the WWW Holdings board of directors out of funds
legally available for distribution. Upon the liquidation of WWW Holdings, WWW
Holdings common stockholders will be entitled, subject to the rights of the
holders of any outstanding WWW Holdings preferred stock, to receive pro rata all
assets, if any, of WWW Holdings available for distribution after the payment of
expenses and all prior claims.

    WWW Holdings will apply to have its common stock listed on The Nasdaq
National Market under the trading symbol "ELNK."

WWW HOLDINGS PREFERRED STOCK IN GENERAL

    The preferred stock of WWW Holdings may be issued in one or more series, and
the WWW Holdings board of directors, acting without the approval of the
stockholders, is authorized to fix the dividend rights and terms, redemption
rights and terms, liquidation preferences, conversion rights, voting rights and
sinking fund provisions applicable to any series of preferred stock.

WWW HOLDINGS SERIES A CONVERTIBLE PREFERRED STOCK

    Prior to the consummation of the merger of EarthLink into WWW Holdings, the
WWW Holdings board of directors will create a series A convertible preferred
stock, with the same terms and conditions as the EarthLink series A convertible
preferred stock. The material terms and conditions of the WWW Holdings series A
convertible preferred stock are as follows:

GENERAL; DIVIDEND RIGHTS

    Sprint will own all of the issued and outstanding shares of WWW Holdings
series A preferred stock and we may originally issue shares of series A
preferred only to Sprint. The series A preferred stockholders are entitled to
receive dividends at a rate per annum of 3% of the liquidation value of their
shares, which is used to determine the cash dividends that the series A
preferred stockholders are entitled to receive, the number of shares of common
stock into which the series A preferred stock may be converted and the amount of
money the series A preferred stockholder will be entitled to receive if the
series A preferred stock is redeemed or WWW Holdings is liquidated, which
dividends will be compounded quarterly. For a period of five years from the
initial issuance date of the series A preferred stock, these dividends are
payable "in kind" by way of an increase in the liquidation value of the shares
and after the end of the five year period are payable in cash. Moreover, upon
WWW Holdings' optional redemption of the series A preferred stock or the
consummation of a merger, share exchange or other extraordinary business
combination during the initial five year period, the holders of the series A
preferred stock will be entitled to receive an accelerated "in kind" dividend
for the entire initial five year period. Beginning on the sixth year after the
initial issuance date of the series A preferred stock, holders of series A
preferred stock will be entitled to receive cumulative quarterly cash dividends
of 3% annually. Beginning on the twenty-first year after the initial issuance
date of the series A preferred stock, holders of the series A preferred stock
will be entitled to cumulative quarterly cash dividends of 8% of the liquidation
value per share, increasing annually to a maximum rate of 12%.

LIQUIDATION RIGHTS

    The holders of WWW Holdings series A preferred stock will receive, prior to
any payment or distribution in respect of other shares of WWW Holdings' capital
stock, an amount per share equal to the average market value of the WWW
Holdings' common stock measured over the thirty day period ending on the initial
issuance date of the series A preferred stock, plus all accrued and unpaid
dividends on the shares, whether in cash or in kind.

CONVERSION RIGHTS

    Beginning on the first anniversary of the initial issuance date of the
series A preferred stock, each share of WWW Holdings series A preferred stock is
convertible into the number of shares of common stock as is determined by
dividing the liquidation value of the shares by a number equal to the average
market value of the WWW Holdings stock measured by the thirty day period ending
on the initial issuance date of the series A preferred stock multiplied by
116.118%. After a period of five years from the initial issuance of the
series A preferred stock, the number by which the liquidation value is divided
will be increased annually by 6%, accruing quarterly. That number is also
subject to adjustment based on changes in capitalization of the WWW Holdings
common stock such as stock splits, stock dividends

                                      160
<PAGE>
and the like. Although conversion of the series A preferred stock is at the
holder's option, conversion is required in the event WWW Holdings consummates a
merger, share exchange or other extraordinary business combination.

OPTIONAL REDEMPTION BY WWW HOLDINGS

    Beginning on the third anniversary of the initial issuance date of the WWW
Holdings series A preferred stock, WWW Holdings may elect to redeem the
outstanding shares of series A preferred stock at a redemption price per share
equal to the liquidation value of the shares of series A preferred stock
assuming the acceleration of various dividends, multiplied by a specified
percentage. The specified percentage is initially equal to 103%, and will be
reduced by 1% annually in each of the subsequent three years, after which it
will be equal to 100%.

VOTING RIGHTS

    The WWW Holdings series A preferred stockholders do not possess general
voting rights. However, the WWW Holdings series A preferred stockholders are
separately entitled to elect two of WWW Holdings' directors. This right
terminates as to one of the directors if the WWW Holdings series A preferred
stockholders fail to maintain at least a 20% equity interest in WWW Holdings on
a fully diluted basis, subject to adjustment, for any three consecutive months,
and will terminate as to both of the directors if the WWW Holdings series A
preferred stockholders fail to maintain at least a 10% equity interest over the
same period. A separate vote of 66 2/3% of the then-outstanding shares of WWW
Holdings series A preferred stock is required in limited situations, including
WWW Holdings' liquidation, dissolution or winding up, or WWW Holdings' taking
specified actions that would adversely affect the rights of the holders of the
WWW Holdings series A preferred stock as a class.

WWW HOLDINGS SERIES B CONVERTIBLE PREFERRED STOCK

    Prior to the consummation of the merger of EarthLink into WWW Holdings, the
WWW Holdings board of directors will create a series B convertible preferred
stock with the same terms and conditions as the EarthLink series B convertible
preferred stock. The terms and conditions of the WWW Holdings series B
convertible preferred stock will identical to the terms and conditions of the
WWW Holdings series A convertible preferred stock, except as follows:

    - The WWW Holdings series B convertible preferred stock is immediately
      junior to the WWW Holdings series A convertible preferred stock, but
      senior to the WWW Holdings common stock and to all other classes or series
      of WWW Holdings preferred stock, other than the series A convertible
      preferred stock, with respect to dividends and rights upon liquidation,
      winding up or dissolution.

    - The series B preferred stockholders, by virtue of their status, have no
      right to elect any directors of WWW Holdings.

WWW HOLDINGS SERIES C CONVERTIBLE PREFERRED STOCK

    Prior to consummation of the merger of EarthLink into WWW Holdings, the WWW
Holdings board of directors will create a series C convertible preferred stock,
with the same terms and conditions as the EarthLink series C convertible
preferred stock. The material terms and conditions of the WWW Holdings series C
convertible preferred stock are as follows:

                                      161
<PAGE>
GENERAL; DIVIDEND RIGHTS

    Apple will own all of the issued and outstanding shares of WWW Holdings
series C preferred stock. The series C preferred stockholders are entitled to
receive dividends on an equal basis with the common stockholders.

LIQUIDATION RIGHTS

    The holders of WWW Holdings series C preferred stock will receive, after any
payment of distribution in respect to the series A and B convertible preferred
stock of WWW Holdings, but prior to any payment or distribution in respect of
other shares of WWW Holdings' capital stock, an amount per share equal to the
price paid for the series C preferred stock, plus all accrued and unpaid
dividends on the shares, if any.

CONVERSION RIGHTS

    Each holder of the series C preferred stock will have the right, after
January 4, 2001, to convert its series C preferred stock shares into common
stock. All shares of the series C preferred stock will automatically convert
into shares of common stock for the following reasons:

    (a) following January 4, 2001, if the holders of more than 66 2/3% of the
       series C preferred stock vote to convert all of the series C preferred
       stock into common stock; or

    (b) if conversion is required to consummate any merger, reorganization,
       business combination or other extraordinary transaction (other than the
       EarthLink-MindSpring reorganization) approved by WWW Holdings' board of
       directors.

VOTING RIGHTS

    The series C preferred stock will be non-voting until January 4, 2001
(except for its right to elect a member to the board of directors as discussed
below under "Board Seat"). After that, it will vote together with the common
stock, and not separately as a class.

BOARD SEAT

    Following the expiration or early termination of any applicable waiting
periods under the Hart-Scott-Rodino Antitrust Improvements Act applicable to
Apple's investment, Apple has the right to name a member to WWW Holdings' board
of directors for so long as WWW Holdings is Apple's exclusive default ISP in the
setup software under the WWW Holdings-Apple Internet services agreement, Apple
holds series C preferred stock and Apple maintains a certain percentage
ownership of the WWW Holdings securities it purchased in its initial investment
in EarthLink and subsequent top-ups. The required ownership percentages are:

    (a) during the first year after January 4, 2000, Apple must maintain
       ownership of 100% of the securities it purchased;

    (b) during the second and third years after January 4, 2000, Apple must
       maintain ownership of at least 75% of the securities it purchased; and

    (c) from the fourth year after January 4, 2000, Apple must maintain
       ownership of at least 50% of the securities it purchased.

                       COMPARISON OF STOCKHOLDERS' RIGHTS

    Each of EarthLink, MindSpring and WWW Holdings is a Delaware corporation
subject to the provisions of Delaware law. Because each of EarthLink, MindSpring
and WWW Holdings is a Delaware corporation, the stockholders of each corporation
are treated the same under Delaware law. However, because of different
provisions in the companies' certificates of incorporation and bylaws, the
rights of the stockholders of the companies will differ in some instances.

    Set forth below are comparisons between the rights of EarthLink
stockholders, MindSpring stockholders and WWW Holdings stockholders under their
respective certificates of incorporation and bylaws. This description summarizes
the material differences that may affect the rights of stockholders of
EarthLink, MindSpring and WWW Holdings, but does not purport to be a complete
statement of all such differences. Stockholders should read the relevant
provisions of the laws and documents discussed below. The description set forth
below also assumes that the certificate of incorporation and bylaws of WWW
Holdings have been amended and restated and that the board of directors of WWW
Holdings has created the series A convertible preferred stock and series B
convertible preferred stock, all of which are required by the reorganization
agreement to take place before the consummation of the reorganization.

LIMITATION OF DIRECTOR LIABILITY

    WWW HOLDINGS AND EARTHLINK.  The certificates of incorporation of WWW
Holdings and EarthLink contain provisions that limit the liability of the
directors of WWW Holdings and EarthLink to the fullest extent permitted under
Delaware law. The provisions eliminate the liability of the WWW Holdings and
EarthLink directors to WWW Holdings and EarthLink and to their respective
stockholders for monetary damages relating to breaches of the directors'
fiduciary duties in their capacity as directors, except for specific breaches
and acts or omissions for which the law of Delaware expressly provides that no
limitation of liability may be effective. Delaware law does not permit
indemnification in the following circumstances:

    - for breach of a director's duty of loyalty to a corporation or its
      stockholders;

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

    - for unlawful distributions; and

    - in respect of any transaction from which a director received an improper
      personal benefit.

    Pursuant to the certificates of incorporation of WWW Holdings and EarthLink,
limitation of liability of directors will not be limited or eliminated by any
amendment or modification of the certificates of incorporation.

    MINDSPRING.  MindSpring's certificate of incorporation provides that no
director of MindSpring will be liable to MindSpring or its stockholders for
monetary damages for a breach of the director's fiduciary duty, except that a
director's liability will not be limited for:

    - any breach of the director's duty of loyalty to MindSpring or its
      stockholders,

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

    - the unlawful payment of dividends, or

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

    Under the certificate of incorporation of MindSpring, limitation of
liability of directors may not be retroactively limited or eliminated by any
amendment or modification of MindSpring's certificate of

                                      163
<PAGE>
incorporation. The MindSpring certificate of incorporation further instructs the
corporation to indemnify directors, officers and agents of MindSpring to the
fullest extent permitted by the Delaware corporation law for claims or
proceedings arising from such individual's relationship with MindSpring.

are elected by an affirmative vote of the holders of the plurality of the votes
of the shares present, in person or by proxy at the meeting and entitled to vote
on the election of directors. The vote of a majority of shares represented at a

in the section entitled "Description of WWW Holdings Capital Stock" beginning on
page 159.


    EARTHLINK.  Each EarthLink stockholder is entitled to one vote for each
share of common stock on all matters required or permitted to be voted on by
stockholders of EarthLink. Cumulative voting is not permitted under EarthLink's
certificate of incorporation. In all elections of directors, directors are
elected by an affirmative vote of the holders of the plurality of the votes of

necessary to approve other actions requiring stockholder approval.

                                      164
<PAGE>
    Although the EarthLink preferred stockholder generally does not have the
right to vote its shares, the series A preferred stockholder does have the right
to elect two directors so long as its ownership of capital stock does not fall
below 20% of the outstanding capital stock of EarthLink on a fully diluted basis
for three consecutive months and it can elect one director so long as its
ownership does not fall below 10% of the outstanding capital stock of EarthLink
on a fully diluted basis for three consecutive months. Apple, the series C
preferred stockholder, has the right to elect a member to EarthLink's board of
directors for so long as EarthLink is Apple's exclusive default ISP in the setup
software under the EarthLink-Apple Internet services agreement, Apple holds
series C preferred stock and Apple maintains a certain percentage ownership of
the EarthLink securities it purchased in the initial investment and subsequent
top-ups. The required ownership percentages are:

    ownership of 100% of the EarthLink securities it purchased;

    (b) during the second and third years after January 4, 2000, Apple must
    maintain ownership of at least 75% of the EarthLink securities it purchased;
    and

    (c) from the fourth year after January 4, 2000, Apple must maintain
    ownership of at least 50% of the EarthLink securities it purchased.

    In addition, the approval of 66 2/3% of the shares of EarthLink series A

preferred stock voting as a class, is required to:

    - change the rights, preferences or privileges of the shares of the series
      of preferred stock;

    - increase the number of the authorized shares of the series of preferred
      stock;

    - create any new series of stock or securities convertible into equity

      enter into any agreements that conflict with EarthLink's obligation to the
      holders of the series of preferred stock; or

    - liquidate EarthLink.

    MINDSPRING.  Each MindSpring stockholder is entitled to one vote for each
share of common stock upon any matter properly considered and acted on by the
stockholders of MindSpring. In all elections of directors, directors are elected
by an affirmative vote of the holders of the plurality of the votes of the
shares present, in person or by proxy at the meeting and entitled to vote in the
election of directors. The vote of a majority of shares represented at a meeting
and entitled to vote at a meeting at which a quorum exists is generally
necessary to approve other actions requiring stockholder approval.

MERGERS, SHARE EXCHANGES AND SALES OF ASSETS

    EARTHLINK, MINDSPRING AND WWW HOLDINGS.  Delaware law generally requires
that any merger, share exchange or sale of all or substantially all the assets
of a corporation not in the ordinary course of business be approved by the
affirmative vote of the majority of the issued and outstanding shares of each
voting group entitled to vote, unless a different vote is required by the
certificate of incorporation or bylaws. The certificates of incorporation and
bylaws of EarthLink, MindSpring and WWW Holdings do not specifically address
mergers, share exchanges or sales of assets; therefore, an affirmative vote of
the majority of the outstanding shares of common stock entitled to vote is
required.

                                      165
<PAGE>
ANTI-TAKEOVER STATUTES

    EARTHLINK, MINDSPRING AND WWW HOLDINGS.  Delaware law contains a number of
provisions that may have the effect of delaying or discovering a hostile
takeover. Delaware law prohibits a Delaware corporation from entering into a
business combination with the beneficial owner of 15% or more of the
corporation's outstanding voting stock, or its affiliates, for a period of three
years after the 15% beneficial owner achieved this level of ownership. Delaware
law permits a business combination with a 15% beneficial owner if: (A) prior to
the date the stockholder becomes a 15% beneficial owner, the board of directors
of the corporation approve either the business combination or the transaction
that will result in the person or entity becoming 15% beneficial owner; (B) the
interested stockholder acquires at least 85% of the corporation's outstanding
voting stock, excluding shares owned by persons who are directors, officers and
by various employee stock plans, in the same transaction in which the
stockholder becomes a 15% beneficial owner; or (C) on or subsequent to the date
of the transaction by which the stockholder becomes a 15% beneficial owner, the
board of directors approves the business combination and by a vote of the
holders of two-thirds of the corporation's outstanding voting stock, not
including shares owned by the 15% beneficial owners. In general, a Delaware
corporation must specifically elect, through an amendment to its bylaws or
certificate of incorporation, not to be governed by these provisions. None of
EarthLink, MindSpring or WWW Holdings has made an election not to be governed by
these provisions and, therefore, each of them is currently subject to these
provisions of the Delaware law.

AMENDMENTS TO CERTIFICATES OF INCORPORATION

    Delaware law provides generally that a Delaware corporation's certificate of
incorporation may be amended by the affirmative vote of the holders of a
majority of the outstanding shares entitled to vote on the matter.


    WWW HOLDINGS.  In addition to the standard Delaware requirement, WWW
Holdings' certificate of incorporation provides that any amendment to the
articles in the certificate of incorporation that govern the board of directors,
indemnification or the amendment of the certificate of incorporation and the
bylaws must be approved by at least two-thirds of the shares entitled to vote on
the amendment and by a majority of the members of the entire board of directors.
The holders of the WWW Holdings preferred stock must approve any amendment to
the certificate of incorporation that would affect the terms of the preferred
stock. See "WWW Holdings Preferred Stock in General" on page 160.



    EARTHLINK.  In addition to the standard Delaware requirement, EarthLink's
certificate of incorporation requires the affirmative vote of a majority of the
votes entitled to be cast by the holders of all of the outstanding shares of
capital stock, voting together as a single class to amend the certificate of
incorporation or bylaws in any manner that is inconsistent with the current
article in the certificate of incorporation governing the board of directors.
The holders of the EarthLink preferred stock must approve any amendment to the
certificate of incorporation that would affect the terms of the preferred stock.
See "Voting; Election of Directors" on page 164.


    MINDSPRING.  MindSpring's certificate of incorporation may be amended in any
manner provided for by law, except that the affirmative vote of the holders of
at least two-thirds of the voting power of all outstanding shares of the capital
stock of MindSpring entitled to vote and the affirmative vote of the majority of
the board of directors are required to amend the provisions of MindSpring's
certificate of incorporation relating to the election of the board of directors,
the limitation of liability and indemnification of officers and directors of
MindSpring and amendment of the certificate of incorporation of MindSpring.

                                      166
<PAGE>
AMENDMENTS TO BYLAWS

    WWW HOLDINGS.  The WWW Holdings certificate of incorporation and bylaws
provide that the bylaws may be amended by stockholders holding a majority of the
number of shares of stock present and entitled to vote at a meeting or by a
majority vote of the directors then in office or except for the provisions
requiring that actions, if taken, be taken by more than a majority of the
directors, which may be amended or repealed by the stockholders in the manner
described above or by the number of directors who are required to act pursuant
to the provision.

    EARTHLINK.  The EarthLink certificate of incorporation and bylaws provide
that the bylaws may be amended by the majority vote of the directors then in
office by stockholders holding a majority of the number of shares of stock
present and entitled to vote at the meeting at which the amendment is to be
voted upon.

    MINDSPRING.  In addition to the right of stockholders to amend MindSpring's
bylaws pursuant to Delaware law, MindSpring's certificate of incorporation
authorizes the board of directors to amend MindSpring's bylaws.

STOCKHOLDER ACTION BY WRITTEN CONSENT

    WWW HOLDINGS AND EARTHLINK.  The stockholders may take any action required
to be taken or that may be taken at any annual or special meeting of
stockholders by written consent without a meeting if the consent is signed by
stockholders who would have had the votes necessary to approve the action at a
meeting at which all shares entitled to vote on the action were present and if
the consent is properly delivered to the company.

    MINDSPRING.  MindSpring's bylaws provide that any action required or
permitted to be taken at a stockholders' meeting may be taken without a meeting
if the action is taken by a unanimous vote of persons who would be entitled to
vote with respect to the action at a meeting. The action must be evidenced by
one or more written consents describing the action taken, signed by all of the
stockholders who would be entitled to vote with respect to the action at a
meeting, and delivered to MindSpring.

BOARD OF DIRECTORS

    WWW HOLDINGS.  WWW Holdings' certificate of incorporation requires that
there be at least two and no more than seventeen directors, with the exact
number of directors to be set by a majority of the board of directors or by the
affirmative vote of the holders of at least a majority of all outstanding shares
entitled to vote in the election of directors, voting as a single class. At the
effective time of the mergers of EarthLink and MindSpring into WWW Holdings, the
board will have thirteen directors. Four directors will be chosen by EarthLink,
four will be chosen by MindSpring, two will be chosen by Sprint, as the
series A preferred stockholder, one will be chosen by Apple, as the series C
preferred stockholder, and the remaining two will be chosen by a committee
selected from among the appointed directors. The board of directors will be a
classified board in which approximately one-third of its directors will stand
for election each year. The initial term of the class I directors will expire at
the annual meeting of stockholders in 2000, the term of the class II directors
will expire at the annual meeting of stockholders in 2001, and the term of the
class III directors will expire at the annual meeting of stockholders in 2002.
In all cases a director will serve until his or her successor is elected and
qualifies, or until he or she resigns, is removed, dies or is incapacitated.

    At each annual meeting of WWW Holdings stockholders the successors to the
class of directors whose term then expires will be elected to hold office for a
term expiring at the third succeeding annual meeting and until their successors
are elected and qualify, except with respect to vacancies and newly created
directorships. Directors will be elected by a plurality of the votes of the
shares of

                                      167
<PAGE>
common stock present in person or represented by proxy at the meeting and
entitled to vote in the election of directors.

    If the number of directors is changed by resolution of the board, any
increase or decrease will be apportioned among the classes so as to keep the
number of directors in each class as nearly equal as possible. No decrease in
the number of directors will shorten the term of an incumbent director.

    Nominations for the election of directors may be made by the board of
directors or a committee appointed by the board. Also, any stockholder of record
who is entitled to vote in the election of directors may nominate persons for
election as directors at a meeting, but only if the stockholder gives written
notice of his intent to make nominations, either personally or by the United
States mail, postage prepaid, to the Secretary of WWW Holdings at least 90 days
before the annual meeting of stockholders, if that is where the nominees are to
be voted upon, or, if the election is to be held at a special meeting, the close
of business on the seventh day following the date that notice of the meeting is
first given to stockholders. Each notice must state:

    - the name and address of the stockholder of record who intends to make the
      nominations and of the persons to be nominated;

    - a representation that the stockholder is a holder of record of shares of
      WWW Holdings entitled to vote at the meeting and intends to appear in
      person or by proxy at the meeting to nominate the persons specified in the
      notice;

    - a description of all arrangements between the stockholder as would be
      required to be included in a proxy statement filed under the then-current
      proxy rules of the Securities and Exchange Commission if the nominees were
      to be nominated by the board of directors; and

    - the consent of each nominee to serve as a director of WWW Holdings if he
      or she is elected.

    Any vacancy on the board of directors that results from an increase in the
number of directors or from a director's death, resignation, retirement,
disqualification or removal from office may be filled by a majority of the board
of directors then in office, even if less than a quorum, or by the stockholders
if the board of directors has not filled the vacancy. Any director elected to
fill a vacancy will have the same remaining term as the director's predecessor.

    At any meeting of stockholders with respect to which notice of the intent to
propose directors has been given, the entire board of directors or any
individual director may be removed, with or without cause, by the affirmative
vote of the holders of a majority of all outstanding shares entitled to be voted
at an election of directors, but if less than the entire board of directors is
to be removed, no director may be removed without cause if the votes cast
against his removal would have been sufficient to elect him if they had been
cumulatively voted at an election of the entire board of directors.

    Whenever the holders of any one or more classes or series of preferred stock
issued by WWW Holdings have the right to elect directors, the election, term of
office, filling of vacancies and other features of those directorships will be
governed by the terms of the certificate of incorporation and the resolutions of
the board of directors creating the class or series. As of the effective time of
the mergers and for so long as its percentage ownership of capital stock does
not fall below 20% of the outstanding capital stock of WWW Holdings on a fully
diluted basis for three consecutive months, the holders of the series A
convertible preferred stock will have the right to elect two directors. So long
as the series A preferred stockholder's percentage ownership does not fall below
10% of the outstanding capital stock of WWW Holdings on a fully diluted basis
for three consecutive months the series A preferred stockholder has the right to
elect one director. The holder of the series C convertible preferred stock will
have the right to elect a director, so long as the stockholder maintains certain
stock ownership levels.

                                      168
<PAGE>
    EARTHLINK.  The certificate of incorporation requires that there be at least
two and no more than thirteen directors. The EarthLink board of directors
currently consists of ten directors, eight of whom are voted upon by the holders
of EarthLink common stock and two of whom are selected by the series A preferred
stockholder. In connection with its ownership of series C preferred stock, Apple
will have the right to elect one director to the EarthLink board, which right
becomes effective upon closing of such transaction. A director of EarthLink
holds his office for a period of one year and until his successor is elected and
qualifies, or until he dies, resigns, retires, is disqualified or is removed.

    EarthLink's procedures for nominations of directors by stockholders are the
same as WWW Holdings' procedures.

    MINDSPRING.  MindSpring's certificate of incorporation provides that its
board of directors will be comprised of three classes as nearly equal in number
as possible, with each class elected for a term of three years, so that a
different class of directors stands for election each year. The MindSpring
bylaws provide that the number of directors may not be less than three nor more
than fifteen. The MindSpring board of directors currently consists of five
directors. A director of MindSpring holds his office until such his successor is
elected and qualified or until his earlier death, resignation or removal.

    At each annual meeting of MindSpring stockholders the successors to the
class of directors whose term then expires will be elected to hold office for a
term expiring at the third succeeding annual meeting and until their successors
are elected and qualify, except with respect to vacancies and newly created
directorships. Directors will be elected by a plurality of the votes of the
shares of common stock present in person or represented by proxy at the meeting
and entitled to vote in the election of directors.

    If the number of directors is changed by resolution of the board, any
increase or decrease will be apportioned among the classes so as to keep the
number of directors in each class as nearly equal as possible. No decrease in
the number of directors will shorten the term of an incumbent director.

    MindSpring's certificate of incorporation provides that if a vacancy occurs
on the MindSpring board, the vacancy may be filled by a majority vote of the
directors then in office, even if they constitute less than a quorum, or by the
sole remaining director. Whenever the holders of any class or classes of
MindSpring stock or series of MindSpring stock are entitled to elect one or more
directors by the provisions of MindSpring's certificate of incorporation,
vacancies and newly created directorships of such class or series may be filled
by a majority of the directors elected by such class or series or by a sole
remaining director elected by such class or series. In the event that one or
more MindSpring directors resigns from the MindSpring board effective at a
future date, a majority of the directors then in office, including those who
have so resigned, may fill such vacancy or vacancies.

    MindSpring's board of directors nominates candidates to stand for election
as directors. Candidates may also be nominated by any MindSpring stockholder,
provided such nominations are submitted in writing to MindSpring no later than
90 days prior to the meeting of stockholders at which such directors are to be
elected, together with the identity of the stockholder making the nomination and
the number of shares of MindSpring stock owned, directly or indirectly, by the
stockholder.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of EarthLink Network, Inc.

    In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of stockholders' equity (deficit) and of
cash flows present fairly, in all material respects, the financial position of
EarthLink Network, Inc. and its subsidiary (the "Company") at December 31, 1997
and 1998, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1998, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

    EarthLink Network, Inc. ("EarthLink" or the "Company") is an Internet
service provider that was formed to help members derive meaningful benefits from
the extensive resources of the Internet.

    The Company has experienced operating losses since inception as a result of
efforts to build its network infrastructure and internal staffing, develop its
systems, and expand into new markets. The Company expects that it will continue
to incur net losses as it continues to expend substantial resources on sales and
marketing as it attempts to rapidly increase its market share. There can be no
assurance that the Company will achieve or sustain profitability or positive
cash flow from its operations.

BASIS OF CONSOLIDATION

    The consolidated financial statements include the accounts of EarthLink
Network, Inc. and its wholly-owned subsidiary EarthLink Operations, Inc.
(Note 2). All intercompany transactions and balances have been eliminated in the
consolidated financial statements.

REVENUES

    Recurring revenues consists of monthly fees charged to members for Internet
access and other ongoing services from monthly Internet service and are
recognized over the period services are provided. Other revenues generally
represent one-time non-refundable set up fees. Incremental revenues are derived
from advertising, content and electronic commerce fees that leverage the value
of the Company's member base and user traffic. Such revenues are recorded as
earned.

CASH AND CASH EQUIVALENTS

    All short-term, highly liquid investments with an original maturity of three
months or less at the date of acquisition are classified as cash equivalents.

ACCOUNTS RECEIVABLE AND DEFERRED REVENUES

    The Company bills for Internet service generally one month in advance.
Accordingly, these non-cancelable advanced billings are included in both
accounts receivable and deferred revenue.

CONCENTRATIONS OF CREDIT RISK

    Financial instruments that potentially subject the Company to concentrations
or credit risk consist principally of cash investments and trade receivables.
The Company's cash investment policies limit investments to short-term,
investment grade instruments. Concentrations of credit risk with respect to
trade receivables are limited due to the large number of members comprising the
Company's member base.

PROPERTY AND EQUIPMENT

    Property and equipment is stated at cost and depreciated using the
straight-line method over the estimated useful life of the assets, which is
generally three years for computers and computer related equipment and five
years for other non-computer furniture and equipment. Leasehold improvements

are amortized using the straight-line method over the shorter of their estimated
lives or the term of the lease, ranging from one to ten years.

EQUIPMENT UNDER CAPITAL LEASE

    The Company leases certain of its data communications and other equipment
under capital lease agreements. The assets and liabilities under capital lease
are recorded at the lesser of the present value of aggregate future minimum
lease payments, including estimated bargain purchase options, or the fair value
of the assets under lease. Assets under capital lease are amortized over the
lesser of their estimated useful lives of three to five years or the term of the
lease.

INTANGIBLES

    Intangible assets consist primarily of rights to customer lists, long-term
marketing agreements, goodwill, deferred financing and other items. The costs
assigned to intangible assets are being amortized on a straight-line basis over
the estimated useful lives of the assets, which range from one to ten years. The
Company regularly reviews the recoverability of intangible assets based on
estimated undiscounted future cash flows from operating activities compared with
the carrying values of the intangibles.

ADVERTISING AND CUSTOMER ACQUISITION COSTS

    Advertising and customer acquisition costs are included in sales and
marketing. Such costs are expensed as incurred. Advertising expenses were
$3.2 million, $5.1 million and $8.8 million in 1996, 1997 and 1998,
respectively.

INCOME TAXES

    Income taxes are accounted for under the liability method. Under this
method, deferred tax assets and liabilities are determined based on differences
between the financial reporting basis and tax basis of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to reverse.

NET LOSS PER SHARE

    The Company adopted Statement of Financial Accounting Standards (SFAS)
No. 128, "Earnings per Share" (EPS) and Staff Accounting Bulletin (SAB) No. 98.
SAB No. 98 states that companies, such as EarthLink, that completed an initial
public offering ("IPO") within the past 5 years and incorporated the SAB No. 83
concept of "cheap stock" in determining pre-IPO EPS data must restate all EPS
data to conform to SFAS No. 128. Accordingly, all EPS data have been restated to
conform to SFAS No. 128. SFAS No. 128 requires a dual presentation of basic and
diluted EPS. Basic EPS represents the weighted average number of shares divided
into net income during a reported period. Diluted EPS reflects the potential
dilution that could occur if securities or other contracts to issue common stock
were exercised or converted into common stock. However, the Company did not
include potential common stock in the calculation of EPS since inception as such
inclusion would have an anti-dilutive effect.

                            EARTHLINK NETWORK, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

COMMON STOCK BASED COMPENSATION

    The Company continues to account for its employee stock based compensation
using the intrinsic value method in accordance with the provisions of Accounting
Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to
Employees," and provides pro forma disclosures in the notes to the consolidated
financial statements (Note 9), as if the measurement provisions of SFAS No. 123
had been adopted.

RECLASSIFICATION

    Certain amounts in the prior year financial statements have been
reclassified to conform to current year presentation.

STOCK SPLIT

    In July 1998 the Company effected a two-for-one stock split. The
accompanying consolidated financial statements and related notes have been
retroactively adjusted to give effect to the stock split.

2. STRATEGIC ALLIANCE WITH SPRINT CORPORATION

    On February 10, 1998, EarthLink entered into certain agreements to establish
a broad strategic relationship (the "Strategic Alliance") with Sprint
Corporation ("Sprint") in the area of consumer Internet access and related
services. In connection with the Strategic Alliance, on June 5, 1998, Sprint
consummated a tender offer for 2.5 million shares of the Company's common stock
at a price per share of $22.50 in cash to each tendering stockholder (the
"Offer"). Immediately following the closing of the Offer, Sprint received
approximately 4.1 million shares of the Company's Series A convertible preferred
stock which has been valued at $135 million, in exchange for (i) transfer to the
Company of Sprint's approximately 130,000 Sprint Internet Passport subscribers,
(ii) aggregate cash consideration of approximately $24 million and (iii) the
exclusive right to use certain ports within Sprint's high-speed data network for
four years. EarthLink and Sprint also entered into a Marketing and Distribution
Agreement which includes a commitment by Sprint to deliver a minimum of 150,000
new subscribers per year for five years through its own channels, EarthLink's
right to be Sprint's exclusive provider of consumer Internet access services for
at least ten years and the right to use Sprint's brand and distribution network
for at least ten years. Sprint has also provided EarthLink with a credit
facility of up to $25 million (increasing to $100 million over three years) in
the form of convertible senior debt. Collectively, the above is referenced to as
the "Sprint Transaction".

    In connection with the Sprint Transaction, a newly-formed subsidiary of the
Company was merged with and into the former EarthLink Network, Inc. (the
"Merger"), pursuant to which (i) the former EarthLink became a wholly-owned
subsidiary of the Company and (ii) each outstanding share of former EarthLink
common stock was converted into one share of common stock of the Company.

    The assets are being amortized on a straight-line basis over the estimated
useful lives as follows: member base amortized over 18 months, the Marketing and
Distribution Agreement amortized over 5 and 10 years, which are the life of the
portion of the contract related to Sprint's provision of additional customers
and the overall contract life relative to the co-branding feature, respectively,
and the excess of consideration over the fair value of net asserts acquired
(goodwill) over 18 months. As such, the member base and goodwill will be fully
amortized by December 31, 1999.

    The following unaudited pro forma consolidated results of operations for the
two years ended December 31 1998, assume the acquisition occurred on January 1,
1997 and 1998, respectivley. These pro forma results have been prepared for
comparative purposes only and do not purport to be indicative of the results of
operations that actually would have resulted had the acquisition occurred on the
date indicated, or which may result in the future.

remaining on the 10% Promissory Notes.

    On March 31, 1998, the Company's $5.0 million Convertible Note payable to

Company's note payable to PSINet, $4.4 million at December 31, 1997, was also
paid off during 1998.

6. CAPITAL STOCK AND MANDATORILY REDEEMABLE EQUITY SECURITIES

INITIAL PUBLIC OFFERING

    On January 22, 1997 the Company commenced its initial public offering. The
offering consisted of 4,000,000 shares of common stock issued at $6.50 per
share. Net proceeds to the Company were approximately $22.8 million. Upon
consummation of the offering 2,727,273 shares of the Company's Series A
redeemable convertible preferred stock were converted to 2,727,248 shares of
common stock. In February 1997, the Underwriter exercised its over-allotment
option and purchased 569,500 shares at the initial public offering price of
$6.50. Net proceeds to the Company were approximately $3.4 million.

CONVERSION OF MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK

    On September 10, 1996, the Company issued 2,727,273 shares of its Series A
redeemable convertible preferred stock to investors including among others,
certain directors, stockholders and the Underwriter associated with the
Company's initial public offering and certain of its associates for
$15 million. Stock issuance costs of $987,000 have been charged to redeemable
convertible preferred stock. Each two shares of the Series A redeemable
convertible preferred stock was automatically converted into one share of common
stock upon consummation of the initial public offering of the Company's common
stock on January 22, 1997.

COMMON STOCK

    On September 19, 1997, the Company closed a private placement of 2,919,518
shares of its unregistered restricted common stock. Net proceeds from the
offering were approximately $15.4 million.

FOLLOW ON PUBLIC OFFERING

    In June 1998 the Company completed a follow on public offering of
3.8 million shares of its common stock at $30 per share. The offering consisted
of 3.0 million shares, including 490,000 shares sold to Sprint in accordance
with its preemptive rights under the Sprint Alliance, and an underwriter's
over-allotment of 720,000 shares. Net proceeds to the Company were approximately
$106.3 million.

6. CAPITAL STOCK AND MANDATORILY REDEEMABLE EQUITY SECURITIES (CONTINUED)

    In January 1998, the Company issued 20,000 shares of its common stock to a
Consultant in lieu of cash for services provided pursuant to a consulting
agreement. The fair value of the shares was recorded as prepaid professional
services and amortized ratably over the term of the contract. Under this
agreement the Company issued 20,000 additional shares of its common stock in
January 1999.

7. CONVERTIBLE PREFERRED STOCK

    All issued and outstanding shares of Series A convertible preferred stock
are held by Sprint (Note 2).

    The Series A convertible preferred stockholders receive dividends at a rate
per annum of 3% of the Liquidation Value (as defined below), compounded
quarterly. For a period of five years from June 1998, such dividends are payable
"in kind" by way of an increase in the Liquidation Value of the shares.
Beginning in June 2003, holders of Series A convertible preferred stock will
receive cumulative quarterly cash dividends of 3% annually. Beginning in
June 2018, holders of the Series A convertible preferred stock are entitled to
cumulative quarterly cash dividends of 8% of the Liquidation Value per share,
increasing annually to a maximum rate of 12%.

    The holders of Series A convertible preferred stock will receive, prior to
any payment or distribution in respect of other shares of the Company's capital
stock, an amount per share equal to the average market value of the common stock
measured over the thirty day period ended June 5, 1998 (the "Average Stock
Price"), plus all accrued and unpaid dividends on such share, whether in cash or
in kind (such amount, the "Liquidation Value").

    Beginning in June 1999, each share of Series A convertible preferred stock
is convertible into such number of shares of common stock as is determined by
dividing the Liquidation Value by the "Conversion Price" in effect at such time.
For the five year period following June 1998, the Conversion Price is equal to
the Average Stock Price multiplied by 116.118%. Thereafter, the Conversion Price
is increased annually by 6%, accruable quarterly. The Conversion Price is also
subject to adjustment based on changes in capitalization of the common stock.
Although conversion of the Series A convertible preferred stock is at the
holder's option, conversion is required in the event the Company consummates
certain business combination transactions.

    Beginning in June 2001, the Company may elect to redeem the outstanding
shares of Series A convertible preferred stock at a redemption price per share
equal to the Liquidation Value of such shares, including the acceleration of
certain dividends, multiplied by a specified percentage. The specified
percentage is initially equal to 103%, and will be reduced by 1% annually in
each of the subsequent three years, and thereafter will be equal to 100%.

    The Series A convertible preferred stockholders do not possess general
voting rights together with holders of common stock. However, the Series A
convertible preferred stockholders are separately entitled to elect two of the
Company's directors. This right terminates as to one of the directors if Sprint
fails to maintain at least a 20% equity interest in EarthLink (on a fully
diluted basis, subject to adjustment) for any three consecutive months, and will
terminate as to both of the directors if Sprint fails to maintain at least a 10%
equity interest over the same period. A separate vote of 66.67% of the
then-outstanding shares of Series A convertible preferred stock is required in
certain limited situations, including liquidation, dissolution or winding up of
the Company, or taking certain actions which would adversely affect the rights
of the holders of the Series A convertible preferred stock as a class.

8. DEDUCTIONS FOR DIVIDENDS ON CONVERTIBLE PREFERRED STOCK

    Dividends on convertible preferred stock are reflected as an increase to net
loss attributable to common stockholders. This adjustment reflects the
liquidation dividend of $4.3 million based on a 3% dividend (Note 7) and the
accretion of a $3.3 million dividend related to the beneficial conversion
feature of the Series A convertible preferred stock in accordance with EITF
Topic No. D-60 based upon the rate at which the preferred stock becomes
convertible.

9. STOCK OPTIONS AND WARRANTS

1995 STOCK OPTION PLAN

    In September 1995, the Company established the EarthLink Network 1995 Stock
Option Plan (the "1995 Plan"). The 1995 Plan provides for the grant of incentive
stock options to purchase shares of common stock to employees of the Company and
non-qualified stock options to employees, officers, directors and consultants of
the Company. During 1998, the Plan was amended to increase the number of
available options from 2,500,000 to 5,700,000. The Plan is administered by a
committee appointed by the Board of Directors which determines the terms of the
options granted, including the exercise price, the number of shares subject to
option, and the option vesting period. The exercise price of all options granted
under the plan must be at least 100% of the fair market value on the date of
grant. Options generally have a maximum term of ten years and vest in equal
quarterly increments over a five year period. As of December 31, 1998, there
were 1,493,176 shares available for issuance under the 1995 Plan.

DIRECTORS STOCK OPTION PLAN

    In September 1995, the Company established the EarthLink Directors Stock
Option Plan (the "Directors Plan"). The Directors Plan, as amended and restated
in December 1996, provides for the grant of options to purchase an aggregate of
125,000 shares of common stock to directors who do not also serve as employees
of the Company and do not beneficially own, nor are employees, directors or
officers of any entity which owns 5% or more of the outstanding shares of the
Company's capital stock. Under the Directors Plan, grants of options to purchase
20,000 and 5,000 shares of common stock are automatically made to each
non-management director at such time as the person first becomes a member of the
Board of Directors and at the beginning of each fiscal year, respectively.
Options generally have a maximum term of ten years and vest in equal quarterly
increments over a five year period. As of December 31, 1998, there were no
outstanding options to purchase shares of common stock under the Directors Plan.

NON-QUALIFIED OPTION GRANTS

    In addition to the options granted under the plans described above, the
Company granted non-qualified stock options to certain employees, officers and
directors. Non-qualified options generally have a maximum term of ten years and
generally vest in equal quarterly increments over a five-year period.

    For 1996, the fair value of each option grant is estimated on the date of
grant using the minimum value method with the following assumptions used for
grants during both periods: dividend yield of 0.0%, risk free interest rate of
5.83% and expected option term of 10 years.

    Had compensation cost been determined on the basis of fair value pursuant to
SFAS No. 123, net loss and net loss per share would have been increased as

10. INCOME TAXES

    At December 31, 1997 and 1998, the Company had net operating loss
carryforwards for federal income tax purposes totaling approximately
$61.0 million, and $106.8 million, respectively, which begin to expire in 2010.
At December 31, 1997 and 1998, the Company had net operating loss carryforwards
for California income tax purposes totaling approximately $48.0 million and
$70.0 million, respectively, which begin to expire in 2001. The Internal Revenue
Code of 1986, as amended, includes provisions which may limit the net operating
loss carryforwards available for use in any given year if certain events occur,
including significant changes in ownership. Due to the Company's initial public
offering and other issuances of common stock and common stock equivalents,
utilization of the Company's net operating loss carryforwards to offset future
income may be limited. The net operating loss includes $24.0 million related to
the exercise of employee stock options. Any benefit resulting from the
utilization of this portion of the net operating loss will be credited directly
to equity.

    Deferred tax assets and liabilities include the following:

11. COMMITMENTS AND CONTINGENCIES

LEASES

    The Company leases its facilities and certain equipment under non-cancelable
operating leases expiring in various years through 2008. Total rent expense in
1996, 1997 and 1998 for all operating leases amounted to $914,000, $1.9 million
and $2.4 million, respectively. The Company also leases equipment, primarily
data communications equipment, under non-cancelable capital leases. Most of the
Company's capital leases include purchase options at the end of the lease term.

    During the three years ended December 31, 1998, the Company financed the
acquisition of data processing and office equipment amounting to approximately
$11.3 million, $10.5 million and $9.3 million, respectively, by entering into a
number of leases and agreements for the sale and leaseback of equipment. The
sale leaseback transactions are recorded at cost, which approximates the fair
market value of the property and, therefore, no gains or losses have been
recorded. The property remains on the books and continues to be depreciated. A
financing obligation representing the proceeds is recorded and reduced based
upon payments under the lease agreement.

    The Company's corporate headquarters and call center are located in a 93,000
square-foot facility in Pasadena, California. Base rent is currently $73,000 per
month. The Company has an option to extend this lease for an additional five
years at the then-prevailing market rate following its expiration in
September 2007. The data center and primary data hub are housed in a 110,000

SIGNIFICANT AGREEMENTS

    Access to the Internet for members outside of the Company's California
regional base is provided through points of presence ("POP") capacity leased
from UUNET and PSINet. EarthLink is, in effect, buying this capacity in bulk at

normal rates. At December 31, 1998, $4.0 million and $4.1 million in amounts due
to UUNET were recorded in accounts payable and other accrued liabilities,
respectively, and $4.7 million in amounts due PSINet were recorded in other
accrued liabilities.

14. SUBSEQUENT EVENTS

    In January 1999 the Company completed a follow on public offering of
2.4 million shares of its common stock at $73.63 per share. The offering
consisted of 2.3 million shares and an underwriter's over-allotment of 99,000
shares exercised in February 1999. Net proceeds to the Company were
approximately $170 million. In conjunction with the offering, Sprint exercised
its preemptive rights to maintain its existing ownership level in the Company.
Accordingly, Sprint purchased 770,000 shares of which 192,000 were common stock
and 578,000 were Series B convertible preferred stock. Series B convertible
preferred stock has the same rights and privileges as Series A convertible
preferred stock, as described in Note 7, except that each Series B share is
convertible into only one share of the Company's common stock. Proceeds from the
sale of shares to Sprint were $54.1 million.

    In February 1999, Sprint exercised its preemptive rights to maintain its
ownership in the Company after the exercise of the underwriter's over-allotment
granted in connection with the aforementioned follow on public offering.
Accordingly, Sprint purchased 38,000 shares of which 9,000 were common stock and
29,000 were Series B convertible preferred stock. Proceeds from the sale of
stock to Sprint were $2.7 million.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

    The condensed consolidated financial statements of EarthLink Network, Inc.,
which include the accounts of its wholly owned subsidiary, EarthLink Operations,
Inc., (collectively, "EarthLink" or the "Company") for the three and nine month
periods ended September 30, 1999 and the related footnote information are
unaudited and have been prepared on a basis substantially consistent with the
Company's audited financial statements as of December 31, 1998 contained in the
Company's Annual Report on Form 10-K, as filed with the Securities and Exchange
Commission (the "Annual Report"). All significant intercompany transactions have
been eliminated. These financial statements should be read in conjunction with
the audited consolidated financial statements and the related notes thereto
contained in the Company's Annual Report. In the opinion of management, the
accompanying unaudited financial statements contain all adjustments (consisting
of normal recurring adjustments) which management considers necessary to present
fairly the financial position of the Company at September 30, 1999 and the
results of operations and of cash flows for the three month and nine month
periods ended September 30, 1999. The results of operations for the three and
nine month periods ended September 30, 1999 are not necessarily indicative of
the results for the entire year ending December 31, 1999.

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

2. RECLASSIFICATIONS

    Certain amounts in prior period financial statements have been reclassified
to conform to the current period presentation.

3. NET LOSS PER SHARE

    The Company has adopted Statement of Financial Accounting Standards (SFAS)
No. 128, "Earnings per Share" ("EPS"). SFAS No. 128 requires a dual presentation
of basic and diluted EPS. Basic EPS represents the weighted average number of
shares outstanding divided into net income attributable to common stockholders
during a reported period. Diluted EPS reflects the potential dilution that could
occur if securities or other contracts to issue common stock were exercised or
converted into common stock. However, the Company has not included potential
common stock in the calculation of EPS as such inclusion would have an
anti-dilutive effect.

4. INTANGIBLE ASSETS AND AMORTIZATION AND TRANSACTION COSTS

    In June 1998, the Company consummated its strategic alliance with Sprint
Corporation (the "Sprint Transaction"). Intangible assets acquired in the Sprint
Transaction are valued as follows:

4. INTANGIBLE ASSETS AND AMORTIZATION AND TRANSACTION COSTS (CONTINUED)

    The assets are being amortized on a straight-line basis over the estimated
useful lives as follows: member base amortized over 18 months, the Marketing and
Distribution Agreement amortized over 5 and 10 years, which are the life of the
portion of the contract related to Sprint's provision of additional customers
and the overall contract life relative to the co-branding feature, respectively,
and the excess of consideration over the fair value of net assets acquired
(goodwill) over 18 months. As such, the member base and goodwill will be fully
amortized by December 31, 1999.

    In addition, a non-recurring Sprint Transaction cost of $1,397,000 was
recorded in June 1998.

5. DEDUCTIONS FOR ACCRETION DIVIDENDS ON CONVERTIBLE PREFERRED STOCK

    The Convertible Preferred Stock issued to Sprint pays liquidation dividends
for the first five years in the form of increases in its Liquidation Value. The
adjustments of $3.4 million and $10.7 million recorded during the three and nine
month periods ended September 30, 1999, respectively, represent liquidation
dividends of $2.2 million and $6.5 million, based on a 3% dividend and accretion
dividends of $1.2 million and $4.2 million, respectively, related to the
beneficial conversion feature of the Convertible Preferred Stock.

6. AGREEMENT TO MERGE WITH MINDSPRING ENTERPRISES

    In September 1999 EarthLink and MindSpring Enterprises Inc. agreed to merge
into a newly formed public company, in a transaction to be accounted for as a
pooling of interests, with MindSpring stockholders receiving one share of the
new company stock for each share of MindSpring stock, and EarthLink stockholders
receiving 1.615 shares of the new company stock in exchange for each share of
EarthLink stock. The combined company will be known as EarthLink and will trade
under the Nasdaq symbol "ELNK." Subject to certain conditions, including
regulatory approvals and approval by both companies' stockholders, the
transaction is expected to close in the first quarter 2000.

7. INVESTMENTS

    In July 1999, the Company committed to invest in eCompanies Venture Group,
LP, ("EVG"), a limited partnership formed to invest in domestic emerging growth
companies, and eCompanies LLC a partnership formed to create, develop and invest
in Internet related ventures. EarthLink Founder and Chairman, Sky Dayton is a
founding partner in both partnerships. In July 1999 EarthLink invested $1.5
million in EVG and has committed to invest an additional $8.5 million and $2.0
million in EVG and eCompanies, respectively. The investments are accounted for
under the cost method of accounting as

to house its permanent Sacramento Call Center. Rent commitments for the 95,000
square feet of space are as follows:

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors
Sprint Corporation

    We have audited the accompanying statement of revenues and direct expenses
of the Consumer Internet Access Services of Sprint Corporation (the "Company")
for the year ended December 31, 1997. This statement is the responsibility of
the Company's management. Our responsibility is to express an opinion on the
statement based on our audit.

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

    The accompanying statement of revenues and direct expenses was prepared for
inclusion in the Registration Statement on Form S-1 of EarthLink Network, Inc.
for purposes of complying with the rules and regulations of the Securities and
Exchange Commission in lieu of the full financial statements required by
Rule 3-05 for the transaction between EarthLink Network, Inc. and Sprint
Corporation. The statement is not intended to be a complete presentation of the
Consumer Internet Access Services of Sprint Corporation revenues and expenses.

    In our opinion, the statement of revenues and direct expenses referred to
above presents fairly, in all material respects, the revenues and direct
expenses described in the note to the statement of revenues and direct expenses
for the Consumer Internet Access Services of Sprint Corporation for the year
ended December 31, 1997, in conformity with generally accepted accounting

SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES

BASIS OF PRESENTATION

    The statements of revenues and direct expenses represent the activities
related to the Consumer Internet Access Services of Sprint Corporation and have
been prepared in connection with the transaction between EarthLink
Network, Inc. and Sprint Corporation. The statements of revenues and direct
expenses are not intended to be a complete presentation of the revenues and
expenses of the Consumer Internet Access Services of Sprint Corporation because
corporate allocated expenses have not been included. Direct expenses are defined
as those costs which were incurred as a direct result of providing Consumer
Internet Access Services and which will no longer be incurred by Sprint
Corporation subsequent to consummation of the transaction with EarthLink
Network, Inc.

    Sprint Corporation began offering Internet access in the fourth quarter of
1996 and any revenues generated and direct operating expenses incurred from
inception through December 31, 1996, were nominal. Sprint Corporation reports
this operation within its "Emerging Businesses Segment" (the "Group") and
maintains the financial information relative to the Internet subscribers in the
Group. Revenues and direct operating expense information are separately
maintained for the Consumer Internet Access Services within the Group. Sprint
Corporation does not, however, separately maintain and account for other costs
and expenses to operate this business and is unable to determine or reasonably
estimate these costs on a historical basis. In addition, Sprint Corporation does
not separately maintain and account for all assets used in the consumer Internet
access services business. Such assets, primarily network related, are recorded
in the other businesses of Sprint Corporation and used by the other divisions of
Sprint Corporation, including the Group. Accordingly, financial statements for
1996 and full financial statements required by Rule 3-05 of Regulation S-X have
not been presented.

    The statements of revenues and direct expenses are not indicative of the
financial condition or results of operations of this business going forward
because of the change in the business and the omission of various operating
expenses.

UNAUDITED FINANCIAL INFORMATION

    The statement of revenues and direct expenses for the three months ended
March 31, 1998 is unaudited. Sprint Corporation believes that such information
includes all adjustments (consisting only of normal recurring adjustments)
necessary to present fairly the revenues and direct expenses related to the
Consumer Internet Access Services of Sprint Corporation.

REVENUE RECOGNITION

    Operating revenues are recognized as services are rendered to customers and
are recorded net of an estimate for uncollectible accounts. The provision for
doubtful accounts for the year ended December 31, 1997 and the three months
ended March 31, 1998 was $723,000 and $471,000 (unaudited), respectively.

          NOTE TO STATEMENT OF ASSETS ACQUIRED AND LIABILITIES ASSUMED
                    OF THE SPRINT INTERNET PASSPORT BUSINESS

                                  JUNE 5, 1998

SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES

BASIS OF PRESENTATION

    The statement of assets acquired and liabilities assumed represents the
acquisition by EarthLink Network, Inc. (the "Company") of the Sprint Internet
Passport business ("SIP") of Sprint Corporation ("Sprint") in a transaction
accounted for as a purchase. The purchase price paid by the Company consisted of
approximately 4.1 million shares of Series A Convertible Preferred Stock, which
has been valued at $135,000,000. In exchange for the Series A Convertible
Preferred Stock, the Company obtained SIP's customer base, cash and access to
Sprint's high-speed data network. Sprint has further provided the Company access
to up to $100 million in convertible debt financing, and has entered into a
Marketing and Distribution Agreement with the Company.

    Sprint Corporation began offering Internet access in the fourth quarter of
1996. Sprint reports this operation within its "Emerging Businesses Segment"
(the "Group") and maintains the financial information relative to the Internet
subscribers in the Group. Revenues and direct operating expense information are
separately maintained for the Sprint Internet Passport business within the
Group. Sprint Corporation does not, however, separately maintain and account for
other costs and expenses to operate this business and is unable to determine or
reasonably estimate these costs on a historical basis. In addition, Sprint
Corporation does not separately maintain and account for all assets used in the
Sprint Internet Passport business. Such assets, primarily network related, are
recorded in the other businesses of Sprint Corporation and used by the other
divisions of Sprint Corporation, including the Group. Accordingly, the Company
has included this statement of assets acquired and liabilities assumed in order
to comply with Rule 3-05 of Regulation S-X.

USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS

    The preparation of the statement of assets acquired and liabilities assumed
in conformity with generally accepted accounting principles requires management
to make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the statement. Actual results could differ from those estimates.

PURCHASE PRICE ALLOCATION

    The purchase price was allocated to the fair value of assets acquired,
consisting of cash and intangible assets related to a customer base, Sprint's
provision of additional customers and the co-branding feature of the Marketing
and Distribution Agreement and the excess of consideration over the fair value
of net assets acquired.

INTANGIBLE ASSETS

    The intangible assets are amortized on a straight-line basis over the
estimated useful lives as follows: customer base amortized over 18 months, the
Marketing and Distribution Agreement amortized over 5 and 10 years, which are
the life of the portion of the contract related to Sprint's provision of
additional customers and the overall contract life relative to the co-branding
feature, respectively, and the excess of consideration over the fair value of
net assets acquired over 18 months. The Company regularly reviews the
recoverability of intangible assets based on estimated undiscounted future cash
flows from operating activities compared with the carrying values of the
intangible assets.

OTHER ACCOUNTS PAYABLE AND ACCRUED LIABILITIES

    The liabilities consist of accrued expenses for incremental acquisition
costs directly attributable to the acquisition, primarily investment banking,
legal and accounting professional fees.

                        PRO FORMA FINANCIAL INFORMATION

    The following unaudited pro forma condensed combined financial statements
give effect to the acquisition by the Company of the Sprint Internet Passport
business ("SIP") of Sprint in a transaction accounted for as a purchase. The
unaudited statements of operations are based on the statements of operations of
the Company and the statements of revenues and direct expenses of SIP appearing
elsewhere in this Prospectus, and combine the results of operations of the
Company and of SIP for the year ended December 31, 1998 and the nine months
ended September 30, 1998 as if the acquisition occurred on January 1, 1998.
These unaudited pro forma financial statements should be read in conjunction
with the historical statement of revenues and direct expenses and notes thereto
of SIP and the historical financial statements and notes thereto of the Company,
both included elsewhere in this Prospectus. The historical statement of revenues
and direct expenses of SIP are not necessarily indicative of the financial
condition or results of operations of such operations on a prospective basis
because of the omission of various operating expenses from such presentation and
the change in the nature and scope of such business as it will be operated by
the Company.

    The purchase price paid by the Company consisted of approximately
4.1 million shares of Series A Convertible Preferred Stock, which has been
valued at $135,000,000. In exchange for the Series A Convertible Preferred
Stock, the Company obtained SIP's customer base of approximately 130,000
members, cash of $23,750,000 and access to Sprint's high-speed data network.
Sprint has further provided the Company access to $25 million (increasing to
$100 million over a three year period) in convertible debt financing, and has
entered into a Marketing and Distribution Agreement with the Company. The
Company acquired no other assets of SIP or Sprint. Accordingly, the purchase
price was allocated to the cash and intangible assets acquired. The excess of
the purchase price over the fair value of the assets acquired was allocated to
goodwill. The final allocation may differ from that used in the unaudited pro
forma condensed combined financial statements. The acquisition was accounted for
using the purchase method.

    Sprint began offering Internet access in the fourth quarter of 1996 and
reported this operation within its Emerging Businesses Segment (the "Group").
Sprint maintained the financial information relative to the Internet subscribers
in the financial statements for the Group. Sprint maintained revenue and direct
operating expense information separately within the Group. Direct operating
expenses include cost of services and products, selling, general and
administrative expense, and depreciation expense. Sprint, however, did not
separately maintain and account for other costs and expenses to operate this
business. The Company is unable to determine or estimate these costs on a
historical and pro forma basis. In addition, Sprint did not separately maintain
and account for all assets used in the individual business. Such assets,
primarily network related, are recorded in the other businesses of Sprint and
used by the other divisions of Sprint in addition to the Group.

                                  (UNAUDITED)

NOTES TO PRO FORMA COMBINED STATEMENTS OF OPERATIONS

    Pro Forma adjustments are as follows:

    a.  The historical SIP revenues and expenses include results from
       January 1, 1998 through June 5, 1998 (the date of acquisition).

    b.  The Company acquired no depreciable assets of SIP. This adjustment
       eliminates the depreciation expense recorded by SIP.

    c.  This entry reflects the amortization of intangible assets as follows:
       customer base amortized over 18 months, the Marketing and Distribution
       Agreement amortized over five and ten years, which are the lives of the
       portion of the contract related to Sprint's provision of customers and
       the overall contract period relative to the co-branding feature,
       respectively, and the excess of purchase price over net assets acquired
       amortized over 18 months. Additional costs to provide service to the
       acquired members are not considered to be material.

    d.  This adjustment reflects the Liquidation Dividends based upon a 3%
       Liquidation Value accretion dividend and the accretion of a dividend
       related to the beneficial conversion feature in accordance with EITF
       Topic No. D-60 based upon the rate at which the preferred stock becomes
       convertible.

    e.  Pro forma share data are based on the number of shares of the Company's
       Common Stock and common equivalent shares that would have been
       outstanding had SIP been acquired on January 1, 1998, but excludes any
       shares purchased by Sprint in the Offer. The Company's common stock
       equivalents have been excluded from the calculation as their effect is
       antidilutive.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To MindSpring Enterprises, Inc.:

    We have audited the accompanying balance sheets of MINDSPRING
ENTERPRISES, INC. (a Delaware corporation) as of December 31, 1998 and 1997 and
the related statements of operations, stockholders' equity, and cash flows for
the three years ended December 31, 1998, 1997 and 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of MindSpring
Enterprises, Inc. as of December 31, 1998 and 1997 and the results of its
operations and its cash flows for the three years ended December 31, 1998, 1997
and 1996 in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

                       DECEMBER 31, 1998, 1997, AND 1996

1. ORGANIZATION AND NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING
   POLICIES

    MindSpring Enterprises, Inc. ("MindSpring" or the "Company") is a national
provider of Internet access. The Company was incorporated in Georgia on
February 24, 1994 and began marketing its services in June 1994. The Company
reincorporated in Delaware and effected a recapitalization in December 1995.

ESTIMATES AND ASSUMPTIONS

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the period.
Actual results could differ from those estimates.

PRESENTATION

    Certain amounts in the prior year financial statements have been
reclassified to conform to the current year presentation.

SOURCES OF SUPPLIES

    The Company relies on third-party networks, local telephone companies, and
other companies to provide data communications capacity. Although management
feels alternative telecommunications facilities could be found in a timely
manner, any disruption of these services could have an adverse effect on
operating results.

CASH AND CASH EQUIVALENTS

    The Company considers all short-term, highly liquid investments with an
original maturity date of three months or less to be cash equivalents. Cash and
cash equivalents are stated at cost, which approximates fair value.

CREDIT RISK

    The Company's accounts receivable potentially subject the Company to credit
risk, as collateral is generally not required. The Company's risk of loss is
limited due to advance billings to customers for services, the use of
preapproved charges to customer credit cards, and the ability to terminate
access on delinquent accounts. In addition, the concentration of credit risk is
mitigated by the large number of customers comprising the customer base. The
carrying amount of the Company's receivables approximates their fair value.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Depreciation and amortization are
provided for using the straight-line method over the estimated useful lives of
the assets, commencing when assets are installed or placed in service. The
estimated useful life for all assets is five years or, for leasehold
improvements, the life of the lease, if shorter.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                       DECEMBER 31, 1998, 1997, AND 1996

EQUIPMENT UNDER CAPITAL LEASE

    The Company leases certain of its data communication and other equipment
under lease agreements accounted for as capital. The assets and liabilities
under capital leases are recorded at the lesser of the present value of
aggregate future minimum lease payments, including estimated bargain purchase
options, or the fair value of the assets under lease. Assets under capital lease
are depreciated over their estimated useful lives of five years, which are
longer than the terms of the leases.

ACQUIRED CUSTOMER BASE

    The Company capitalizes specific costs incurred for the purchase of customer
bases from other Internet Service Providers ("ISPs"). The customer acquisition
costs include the actual fee paid to the selling ISP, as well as legal and other
expenses specifically related to the transactions. Subscriber acquisition costs
capitalized at December 31, 1998 and 1997 were $47,521,000 and $13,209,000,
respectively. Amortization is provided using the straight-line method over three
years commencing when the customer base is received. Amortization expense for
the years ended December 31, 1998, 1997, and 1996 was $7,048,000, $4,210,000,
and $1,521,000, respectively. See Note 2 for further discussion.

LONG-LIVED ASSETS

    The Company periodically reviews the values assigned to long-lived assets,
such as property and equipment and acquired customer bases, to determine whether
any impairments are other than temporary. Management reviews the undiscounted
projected cash flows related to such assets and compares them to the carrying
values of the assets to determine if an impairment has occurred. If an asset is
deemed to be impaired, the Company records the difference between the projected
cash flows on a discounted basis or the fair market value (whichever is more
appropriate) and the carrying value as an asset impairment charge in the period
incurred. There are no such impairments in the periods presented. Management
believes that the long-lived assets in the accompanying balance sheets are
appropriately valued.

INCOME TAXES

    Deferred income taxes are recorded using enacted tax laws and rates for the
years in which the taxes are expected to be paid. Deferred income taxes are
provided for items when there is a temporary difference in recording such items
for financial reporting and income tax reporting.

STOCK-BASED COMPENSATION PLANS

    The Company accounts for its stock-based compensation plans under Accounting
Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
Employees." The disclosure option of Statement of Financial Accounting Standards
("SFAS") No. 123, "Accounting for Stock-Based Compensation" requires that
companies which do not choose to account for stock-based compensation as
prescribed by this statement shall disclose the pro forma effects on earnings
and earnings per share as if SFAS No. 123 had been adopted.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                       DECEMBER 31, 1998, 1997, AND 1996

REVENUE RECOGNITION

    The Company recognizes revenue when services are provided. Services are
generally billed one month in advance. During 1998, the Company began offering
prepaid services. Advance billings including prepaid services and collections
relating to future access services are recorded as deferred revenue and
recognized as revenue when earned.

BARTER TRANSACTIONS

    The Company engages in certain exchanges of services for advertising and
promotional services. The Company records these transactions at the market value
of the services provided. Such transactions are not material for the periods
presented.

ADVERTISING COSTS

    The Company expenses all advertising costs as incurred.

NET INCOME (LOSS) PER SHARE

    The Company calculates net income (loss) per share as required by SFAS
No. 128, "Earnings Per Share." Basic earnings (loss) per common share ("EPS")
was computed by dividing net income (loss) by the weighted average number of
shares of common stock outstanding for the year ended. The effect of the
Company's stock options (using the treasury stock method) was included in the
computation of diluted EPS for the year ended December 31, 1998. For the years
ended December 31, 1997 and 1996, the effect of the options is excluded as their
effect is anti-dilutive. The following table summarizes the shares used in the
calculations:

any impact on the Company's financial statements as the Company does not have
any "comprehensive income" type earnings (losses) and its financial statements
reflect how the "key operating decisions maker" views the business. The Company
will continue to review these statements over time, in particular SFAS 131, to
determine if any additional disclosures are necessary based on evolving
circumstances.

2. CUSTOMER BASE ACQUISITIONS

    On June 28, 1996, the Company entered into a purchase agreement (as amended
on January 27, 1997, the "Purchase Agreement") with PSINet Inc. ("PSINet"),
pursuant to which the Company agreed to acquire certain of the tangible and
intangible assets and rights related to the consumer dial-up Internet access
services provided by PSINet in the United States, including (i) certain of
PSINet's individual subscriber accounts and (ii) the lease for a customer
support call center near Harrisburg, Pennsylvania (the "Harrisburg Facility"),
and all related telephone switches and other equipment (the "Assets") for
$12,929,000 (excluding accrued interest and increases in principal amount under
the First and Second PSINet Notes previously paid by the Company) (the "Purchase
Price"). In connection with fixing the aggregate amount of the Purchase Price,
the Company and PSINet amended the Second PSINet Note to, among other things,
reduce the principal amount owed thereunder to $3,078,000, an amount equal to
the remaining balance of the Purchase Price as of January 24, 1997. As amended,
the Second PSINet Note no longer accrued interest, was payable over a two-year
period, and was discounted for financial statement purposes using the same rate
of interest (Prime + 3%) as the prior PSINet Notes. The Company accreted the
difference between the principal and total payable amount of $3,078,000 over the
two years of the note.

    In connection with the PSINet transaction, the parties also entered into a
network services agreement (as amended, the "Services Agreement") which enables
MindSpring to offer nationwide Internet access through PSINet's network of over
200 points of presence ("POPs"). The term of the Services Agreement is 5 years
commencing on June 28, 1996 and is automatically renewable annually thereafter
unless either party notifies the other in writing not less than 12 months prior
to the end of such 5-year period or any 12-month extension thereof. Either party
may terminate the Services Agreement at any time upon 60 days' written notice
without penalty. The Company and PSINet amended the Services Agreement effective
January 1, 1997 to provide for certain discounts to the monthly service fees
which otherwise would have been payable by the Company to PSINet. The Company
earned credits of $2,000,000 and $2,050,000 during 1998 and 1997, respectively,
and the discounts are reflected as reductions of cost of revenue. This
arrangement ended in October 1998.

    On September 10, 1998, MindSpring entered into an Asset Purchase Agreement
with America Online, Inc. ("AOL") and Spry, Inc. ("Spry"), a wholly owned
subsidiary of AOL, to purchase certain assets used in connection with the
consumer dial-up Internet access business operated by Spry (the "Spry
Agreement"). Pursuant to the Spry Agreement, MindSpring acquired Spry's
subscriber base of individual Internet access customers in the United States and
Canada as well as various assets used in serving those customers, including a
customer support facility and a network operations facility in Seattle,
Washington. MindSpring also acquired all rights held by Spry to the "Spry" name.
The acquisition was closed on October 15, 1998 and in accordance with the
agreement MindSpring paid the initial payment of $25,000,000 in cash to AOL The
ultimate purchase price for these assets was based primarily upon the number of
acquired subscribers who remain active with MindSpring as continuing users in
good standing as of December 31, 1998. The Company has calculated the final
purchase price to be approximately $32,000,000 and has accordingly accrued an
additional $7,000,000 in the accompanying balance sheet. The transaction is
being accounted for as a purchase. See Note 10 for further discussion.

3. STOCKHOLDERS' EQUITY

    At the annual meeting of stockholders in May 1998 the Company voted to
approve and adopt an amendment to Article 4 of the Company's Amended and
Restated Certificate of Incorporation to increase the number of authorized
shares of $.01 par value common stock from 15,000,000 to 60,000,000 and to
eliminate the Company's Class C Preferred Stock.

    STOCK SPLIT

    On June 24, 1998 the Company effected a three-for-one stock split of the
outstanding shares of common stock in the form of a stock dividend. Accordingly,
all data shown in the accompanying financial statements and notes has been
retroactively adjusted to reflect the stock split.

    COMMON STOCK

    In June 1998, the Company issued 3,000,000 shares at a public offering price
of $17.67. The total proceeds of the offering, net of underwriting discounts and
offering expenses, were approximately $49,756,000.

    In December 1998, the Company issued 2,300,000 shares at a public offering
price of $57.00. The total proceeds of the offering, net of underwriting
discounts and offering expenses, were approximately $124,784,000.

4. STOCK-BASED COMPENSATION PLANS

EMPLOYEE STOCK OPTION PLAN

    Under the Company's 1995 Stock Option Plan, as amended (the "Stock Option
Plan"), 3,000,000 shares of common stock are reserved and authorized for
issuance upon the exercise of options. All employees of the Company are eligible
to receive options under the Stock Option Plan. The compensation committee of
the Board of Directors administers the Stock Option Plan. Options granted under
the Stock Option Plan are intended to qualify as incentive stock options under
Section 422 of the Internal Revenue Code of 1986, as amended. Options generally
become exercisable as follows: (i) 50% of the options become exercisable two
years after the date of grant or, in certain cases, the commencement date of the
holder's employment; (ii) an additional 25% of the options become exercisable
three years after the date of grant or, in certain cases, the commencement date
of the holder's employment; and (iii) the remaining 25% of the options become
exercisable four years after the date of grant or, in certain cases, the
commencement date of the holder's employment. Except as noted in the next
sentence, all options were granted at an exercise price equal to the estimated
fair value of the common stock on the dates of grant as determined by the Board
of Directors based on equity transactions and other analyses. Options granted to
holders of 10% or more of the outstanding common stock were granted at an
exercise price equal to 110% of the estimated fair value of the common stock on
the dates of grant as determined by the Board of Directors based on equity
transactions and other analyses. The options expire ten years from the date of
grant or, in certain circumstances, the commencement date of the option holder's
employment.

DIRECTORS' STOCK OPTION PLAN

    Under the Company's Directors' Stock Option Plan (the "Directors' Plan"),
adopted in December 1995, 210,000 shares of common stock are authorized for
issuance to nonemployee directors (in the form of 30,000 options per director)
upon their initial election or appointment to the board or, in the case of
directors who joined the board prior to the creation of the Directors' Plan,
upon the adoption of the Directors' Plan by the Board of Directors. The
Directors' Plan, as amended by the Board of Directors on March 25, 1998 and
approved by the stockholders on May 20, 1998, provides for discretionary option
grants. Options become exercisable as follows: (i) 50% of the options become
exercisable two years after the date of grant, (ii) an additional 25% of the
options become exercisable three years after the date of grant, and (iii) the
remaining 25% of the options become exercisable four years after the date of
grant. All options were granted at an exercise price equal to the estimated fair
value of the common stock at the dates of grant as determined by the Board of
Directors based upon equity transactions and other analyses. The options expire
ten years from the date of grant.

STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123

    During 1995, the Financial Accounting Standards Board issued SFAS No. 123,
which defines a fair value-based method of accounting for an employee stock
option or similar equity instrument and encourages all entities to adopt that
method of accounting for all of their employee stock-based compensation plans.
However, it also allows an entity to continue to measure compensation cost for
those plans using the method of accounting prescribed by APB No. 25. Entities
electing to remain with the accounting in APB No. 25 must make pro forma
disclosures of net income and, if presented, earnings per share as if the fair
value-based method of accounting defined in this statement had been applied.

    The Company has elected to account for its stock-based compensation plans
under APB No. 25; however, the Company has computed for pro forma disclosure
purposes the value of all options granted during 1998, 1997, and 1996 using the
Black-Scholes option-pricing model as prescribed by SFAS No. 123 using the
following weighted average assumptions used for grants in 1998, 1997, and 1996:

    The total value of options granted during 1998, 1997, and 1996 was computed
as approximately $38,679,000, $3,735,000 and $601,000, respectively, which would
be amortized on a pro forma basis over the four-year vesting period of the
options. If the Company had accounted for these plans in

EMPLOYEE BENEFIT PLAN

    The Company has a savings plan (the "Savings Plan") that qualifies as a
deferred salary arrangement under Section 401(k) of the Internal Revenue Code.
Under the Savings Plan, participating employees may defer a portion of their
pretax earnings, up to the Internal Revenue Service annual contribution limit.
Annually, the Company determines whether to make a discretionary matching
contribution equal to a percentage, determined by the Company, of the employee's
deferred compensation contribution. The Company has not made any matching
contributions to the Savings Plan.

5. RELATED-PARTY TRANSACTIONS

    The Company has entered into certain business relationships with several
subsidiaries and affiliates of ITC Holding Company, Inc. ("ITC Holding"). Except
as noted below, none of these transactions were material for the periods
presented.

    The Company purchases long-distance telephone services and wide area network
transport service from ITC^DeltaCom, Inc. ("ITC^DeltaCom"), a related party
through relationships with ITC Holding. Long-distance charges from ITC^DeltaCom
totaled approximately $3,672,000, $1,942,000 and $677,000 for the years ended

    The Company's net operating loss carryforwards will expire between 2009 and
2012 unless utilized. Due to the fact that prior to 1998 the Company incurred
losses since inception, the Company did not recognize the income tax benefit of
the net operating loss carryforwards. Management provided a 100% valuation
reserve against its net deferred tax asset, consisting primarily of net
operating loss carryforwards. Management reviewed this position based on the net
income generated in 1998 as well as the projections of future income and
determined that it was more likely than not that the deferred tax assets would
be realized. Accordingly, the Company reversed its entire valuation allowance in
1998. In addition, the Company's ability to recognize the benefit from the net
operating loss carryforwards could be limited under Section 382 of the Internal
Revenue Code if ownership of the Company changes by more than 50%, as defined.

10. SUBSEQUENT EVENT

ACQUISITION

    On February 17, 1999, MindSpring acquired certain tangible and intangible
assets and rights used in connection with the Internet services business
operated in the United States by NETCOM On-Line Communication Services, Inc.
("NETCOM"), a Delaware corporation and an indirect wholly owned subsidiary of
ICG Communications, Inc., including (i) approximately 400,000 of NETCOM's
individual Internet access accounts; (ii) approximately 3,000 dedicated Internet
access accounts; (iii) approximately 18,000 Web hosting accounts; and
(iv) various assets used in serving those subscribers, including leased
operations facilities in San Jose, California and Dallas, Texas and all of
NETCOM's rights to the "NETCOM" name (except in Brazil, Canada and the United
Kingdom). The acquisition was effected pursuant to an Asset Purchase Agreement
dated January 5, 1999 between MindSpring and NETCOM. MindSpring paid NETCOM
approximately $245,000,000, including $215,000,000 in cash and $30,000,000 in
MindSpring stock.

    The NETCOM operations outside the United States are not included in this
transaction. In addition, NETCOM (which will change its name in the near future)
will retain all of the assets used in connection with its network operations.
Under a separate network services agreement, NETCOM (operating under a new
corporate name) will sell MindSpring wholesale access to its network. The
agreement has an initial term of one year with an option for a second year on
potentially different terms to be negotiated and accepted by both parties.

    The transaction will be accounted for as a purchase. The purchase price will
be allocated to the underlying assets purchased and liabilities assumed based on
their fair market values at the acquisition date.

of 51% of the lenders. The credit facility has an interest rate of either the
bank rate plus 25 to 100 basis points (defined as the banks prime rate or the
overnight federal funds rate plus 50 basis points) or LIBOR plus 125-200 basis
points depending upon the ratio of total debt to EBITDA. The facility is
available for 36 months and contains certain restrictive covenants including
certain financial ratios. Additionally, borrowings are secured by all assets and
properties. To complete the NETCOM acquisition, the Company borrowed
$80 million under this facility. The proceeds from any future debt issuances and
certain sales of assets and insurance proceeds must be used to repay any
outstanding borrowings.

                    CONDENSED NOTES TO FINANCIAL STATEMENTS

                          SEPTEMBER 30, 1999 AND 1998

1.  Certain information and footnote disclosures normally included in financial
    statements prepared in accordance with generally accepted accounting
    principles have been condensed or omitted pursuant to Article 10 of
    Regulation SX of the Securities and Exchange Commission. The accompanying
    unaudited condensed financial statements reflect, in the opinion of
    management, all adjustments necessary to achieve a fair statement of the
    Company's financial position and results for the interim periods presented.
    All such adjustments are of a normal and recurring nature. These condensed
    financial statements should be read in conjunction with the financial
    statements and notes thereto included elsewhere in this joint proxy
    statement.

    On May 25, 1999, the Company declared a two-for-one stock split in the form
    of a stock dividend which was paid on June 25, 1999 to shareholders of
    record on June 11, 1999. Accordingly, the stock split has been recognized in
    these financial statements by reclassifying approximately $317,000, the par
    value of the additional shares issued as a result of the split, from
    additional paid in capital to common stock. For all periods presented, all
    shares outstanding and per share amounts have been restated to reflect the
    stock split.

1.  Basic (loss) earnings per common share ("EPS") was computed by dividing net
    (loss) income by the weighted average number of shares of common stock
    outstanding for the period then ended. The effect of the Company's stock
    options (using the treasury stock method) was included in the computation of
    diluted EPS for the three and nine months ended September 30, 1998. For the
    nine months ended September 30, 1999, the effect of the options is excluded,
    as it is anti-dilutive. The effect of the potential conversion of the
    Company's 5% Convertible Subordinated Notes due 2006 is anti-dilutive and as
    such is excluded from diluted earnings per share for the nine months ended
    September 30, 1999. The following table summarizes the shares used in the
    calculations:

1.  On February 17, 1999, the Company completed its acquisition of certain
    assets used in connection with the United States Internet access and Web
    hosting business operated by NETCOM On-Line Communication Services Inc.,
    which subsequently changed its name to ICG Netahead, Inc. and is a wholly
    owned subsidiary of ICG Communications, Inc. In this transaction, the
    Company acquired NETCOM's subscriber base of approximately 408,000
    individual Internet access accounts, 25,000 Web hosting accounts and 3,000
    dedicated Internet access accounts in the United States. The Company paid
    NETCOM approximately $245 million, consisting of $215 million in cash and
    $30 million in MindSpring common stock (752,232 shares, at a price per share
    of $38.88). The Company also incurred expenses of approximately
    $4.2 million in connection with this acquisition.

                          SEPTEMBER 30, 1999 AND 1998

        The following table summarizes the net assets purchased in connection
    with this acquisition and the amount attributable to intangibles (in
    thousands):

<TABLE>

</TABLE>

        The preliminary estimate of net assets acquired represents management's
    best estimate based on currently available information; however, such
    estimate may be revised up to one year from the acquisition date. The
    Company is amortizing the acquired customer base over three years.

1.  In March 1999, the Company filed a universal shelf registration statement
    with the Securities and Exchange Commission for the public offering from
    time to time of up to $800 million of debt and equity securities. In
    April 1999, the Company completed two public offerings of securities under
    this shelf regis tration statement. The Company sold 5,520,000 shares of
    common stock, raising net proceeds of approximately $263.2 million, out of
    which the Company repaid all amounts outstanding under its secured credit
    facility. The Company also sold $179,975,000 aggregate principal amount of
    5% Convertible Subordinated Notes due 2006, raising net proceeds of
    approximately $174.1 million. The remaining proceeds from these offerings
    will be used for expansion of our business, as additional working capital
    for general corporate purposes, and for strategic acquisitions of subscriber
    accounts and complementary businesses.

    The notes may be converted into shares of common stock of the Company at any
    time before their maturity or their redemption by the Company at a rate of
    16 shares per each $1,000 principal amount of notes, or $62.50 per share,
    subject to adjustment in circumstances. Interest is payable semiannually on
    April 15 and October 15 of each year beginning October 15, 1999. The notes
    are subordinated in right of payment to all senior debt of MindSpring.

    The Company may redeem the notes before April 15, 2002, in whole or in part,
    at a redemption price equal to principal amount of the note plus accrued and
    unpaid interest, if any, to the redemption date, if the closing price for
    MindSpring's common stock has exceeded 150% of the conversion price for at
    least 20 trading days within a period of 30 consecutive trading days ending
    on the trading prior to the date of the mailing of the notice of redemption.
    The Company will make an additional payment of cash with respect to the
    notes called for redemption of $200 per $1,000 note, less the amount of
    interest actually paid on such note prior to the call for redemption.
    Further the Company may redeem the notes on or after April 15, 2002 at
    102.86% of the principal amount declining to 100% by April 15, 2006.
    Noteholders have the option, subject to certain conditions, to require the
    Company to repurchase any notes held in the event of a "Change in Control,"
    at a price equal to 100% of the principal amount of the notes, plus accrued
    interest to the date of repurchase.

1.  On September 23, 1999, the Company announced that it had entered into an
    Agreement and Plan of Reorganization, dated September 22, 1999 (the "Merger
    Agreement"), with Earthlink Network, Inc. ("Earthlink"). The Merger
    Agreement sets forth the terms and conditions of the proposed Merger of
    MindSpring and Earthlink into a new company (the "Merger"). The Merger is
    structured to be a stock-for-stock Merger of equals. Pursuant to the Merger
    Agreement, each share of common stock of MindSpring will be converted into
    one share of common stock of the new company, and each share of common stock
    of Earthlink will be converted into 1.615 shares of

    common stock of the new company. Other outstanding securities of the two
    companies will be converted on the same basis. Upon consummation of the
    Merger, the new company will be renamed Earthlink, Inc. The parties intend
    for the Merger to be treated as a tax-free reorganization under Section 368
    of the Internal Revenue Code of 1986, as amended, and as a
    "pooling-of-interests" for accounting purposes. Subject to several
    conditions, including receipt of required regulatory approvals, approval by
    both companies' shareholders, and certain third-party consents, the Merger
    is expected to close in the first quarter of 2000. For a more detailed
    discussion of the Merger, see MindSpring's Current Report on Form 8-K filed
    with the Securities and Exchange Commission on September 30, 1999 and the
    amendment to such report on Form 8-K/A filed on October 12, 1999.

To Spry, Inc.:

    We have audited the accompanying balance sheets of SPRY, INC. (a Washington
corporation) as of April 30, 1997 and January 31, 1998 and the related
statements of operations, shareholders' (deficit) equity, and cash flows for the
years ended April 30, 1996 and 1997 and the nine months ended January 31, 1998.
These financial statements are the responsibility of Spry's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Spry, Inc. as of April 30,
1997 and January 31, 1998 and the results of its operations and its cash flows
for the years ended April 30, 1996 and 1997 and the nine months ended

1. ORGANIZATION AND NATURE OF BUSINESS

    Spry, Inc. ("Spry" or the "Company") was organized in February 1989 and over
the periods has been engaged in providing Internet access and services and
selling Internet software. On February 4, 1995, H&R Block, Inc. ("H&R") issued
an aggregate of approximately 404,000 shares of its non-voting delayed
convertible preferred stock, options for an additional 52,000 shares thereof,
and $41,800 in cash to the shareholders of Spry in exchange for all of the
outstanding common stock, preferred stock, and stock options of Spry. This
acquisition was accounted for as a purchase. On January 30, 1996, H&R dividended
Spry to CompuServe Corporation. This was accounted for as a transfer of assets
under common control so carryover basis was employed. On January 31, 1998,
America Online, Inc. ("AOL") acquired the worldwide interactive services
division of CompuServe Corporation ("CompuServe"), including CompuServe's
wholly-owned subsidiary, Spry, in a transaction accounted for as a purchase
(Note 10). Collectively, H&R, CompuServe, and AOL are herein referred to as the
"Parent Corporation."

    The Company initially sold prepackaged software to connect to the Internet
principally utilizing its "Internet in a Box" and "Mosaic in a Box" products. As
access to the Internet became increasingly prevalent, the Company switched its
focus to being a subscriber based Internet service provider. Beginning in
mid-1997, the Parent Corporation began an effort to dispose of Spry, and
advertising and marketing efforts were significantly reduced. Accordingly,
selling, general, and administrative costs decreased while subscriber growth
slowed and eventually began to decline.

    The financial statements and related footnotes contained herein reflect the
operations of Spry's customer base of individual Internet access subscribers,
principally in the United States, which includes subscribers to Spry's "Internet
in a Box" family of products, and other service revenue. A portion of Spry's
assets including its subscriber base, intellectual property and facilities are
being acquired in a transaction accounted for as a purchase by MindSpring
Enterprises, Inc. ("MindSpring") (Note 10).

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    PRESENTATION

    The financial statements of Spry have been derived from the consolidated
financial statements of its Parent Corporations and have been prepared to
present the Company's financial position, results of operations, and cash flows
on a stand-alone basis. Accordingly, the accompanying financial statements
include certain costs and expenses which have been allocated to Spry from its
Parent Corporations (Note 8). These costs have been allocated on a pro rata
basis based on a variety of factors, including revenues, and represent
management's best estimates of what such expenses would have been had Spry been
operated as a separate entity.

    QUARTERLY INFORMATION

    The balance sheet as of July 31, 1998 and the statements of operations and
cash flows for the six months ended July 31, 1998 and 1997 are unaudited and
have been prepared by management of the Company in accordance with the rules and
regulations of the Securities and Exchange Commission. In the opinion of
management, the statements contain all adjustments (consisting of only normal
recurring

items) necessary for the fair presentation of the financial position and results
of operations for the interim periods. The results of operations for the six
months ended July 31, 1998 are not necessarily indicative of the results to be
expected for the entire year.

    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amount of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

    CASH AND CASH EQUIVALENTS

    For purposes of the statements of cash flows, Spry considers all highly
liquid investments with an original maturity of three months or less to be cash
equivalents. The cash and cash equivalents reflected in the accompanying balance
sheets represent specific accounts associated with Spry.

    Certain other cash accounts are commingled with Parent Corporation funds and
Spry's portion is reflected in Due to Parent in accordance with the accompanying
balance sheets.

    REVENUE RECOGNITION

    Spry recognizes revenues when Internet services are provided. Spry bills in
arrears so accounts receivable includes certain services that have not yet been
billed.

    Spry recognizes revenues on the sale of prepackaged software when products
are shipped, net of an allowance for potential returns based on historical
patterns.

    CREDIT RISK

    Spry's accounts receivable potentially subject it to credit risk, as
collateral is not generally required. Spry's risk of loss is limited due to the
use of preapproved charges to customer credit cards and the ability to terminate
access on delinquent accounts. The concentration of credit risk is mitigated by
the large number of customers comprising the customer base. The carrying amount
of Spry's receivables approximates their fair value.

    PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost and are depreciated using the
straight-line method over the estimated useful lives of three to five years.

    In conjunction with the AOL acquisition, the carrying value of property and
equipment was adjusted to its fair market value which approximated book value.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    SOFTWARE DEVELOPMENT COSTS

    Spry capitalizes costs incurred for the production of computer software used
in the sale of its services, including direct labor and related overhead. All
costs in the software development process that are classified as research and
development are expensed as incurred until technological feasibility has been
established. For all periods presented, research and development costs were not
material. Once technological feasibility has been established, such costs are
capitalized until the software is commercially available. Amortization is
provided over three years. It is reasonably possible that the estimates of
anticipated future revenues, the remaining estimated economic life of the
product, or both will be reduced significantly in the near term due to
competitive pressures.

    LONG-LIVED ASSETS

    Spry periodically reviews the values assigned to long-lived assets, such as
property and equipment, software development costs, and goodwill and other
intangibles to determine whether any impairments are other than temporary.
Management believes that the long-lived assets in the accompanying consolidated
balance sheets are appropriately valued.

    GOODWILL

    Goodwill, which is being amortized over 10 years, relates to the pushdown of
the new accounting basis resulting from the acquisition of the Company by H&R,
and subsequently by AOL.

    DUE TO/FROM PARENT

    Spry either advances funds to or borrows funds from its Parent Corporations.
Funds advanced to Spry are used to cover fixed asset expansion, acquisitions,
and working capital requirements. The advances and borrowings are netted and are
reflected in Due to/from Parent in the accompanying balance sheets. The advances
are not evidenced by any written agreement, and are non-interest bearing.

    ADVERTISING COSTS

    Spry expenses all advertising costs as incurred.

    INCOME TAXES

    The income tax returns of its Parent Corporations have included the
operations of Spry. For purposes of these financial statements, income taxes
related to Spry have been computed and recorded on a separate return basis based
on the statutory rates in effect (Note 6).

    Deferred income taxes are recorded using enacted tax laws and rates for the
years in which the taxes are expected to be paid. Deferred income taxes are
provided for items when there is a temporary difference in recording such items
for financial reporting and income tax reporting.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    SOURCES OF SUPPLIES

    Spry is dependent on related parties (Note 8) and third-party suppliers for
its Internet access. Certain of these suppliers are or may become competitors of
Spry, are or have been affiliates of Spry, and such suppliers are not subject to
any restrictions upon their ability to compete with Spry. To the extent that
these suppliers change their pricing structures, Spry may be adversely affected.
Regulatory proposals are pending that may affect the prices charged by certain
suppliers to Spry. Although management feels alternative telecommunications
facilities could be found in a timely manner, any disruption of these services
could have an adverse effect on operating results.

    Spry is also dependent on certain third-party suppliers of hardware
components. Although Spry attempts to maintain a minimum of two vendors for each
required product, certain components used by Spry in providing its networking
services are currently acquired or available from only one source. A failure by
a supplier to deliver quality products on a timely basis, or the inability to
develop alternative sources if and as required, could result in delays which
could materially adversely affect Spry. As Spry's suppliers revise and upgrade
their equipment technology, Spry may encounter difficulties in integrating the
new technology into its network.

3. PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost and are depreciated on the
straight-line method over the estimated useful lives of the assets, which range
from three to five years, and consist of the following:

and $1,090, respectively.

    LEGAL PROCEEDINGS

    Spry is subject to legal proceedings and claims which arise in the ordinary
course of business. There are no pending legal proceedings to which Spry is a
party which management believes are material.

5. STOCK OPTION PLANS

    SPRY STOCK OPTION PLAN

    Under the Company's 1995 stock option plan (the "Spry 1995 Plan"), as
adopted on February 13, 1995 and subsequently amended in April 1995 upon H&R's
purchase of Spry, selected employees, directors, officers, agents, consultants,
advisors, and independent contractors of the company were eligible to receive
options under the Spry 1995 Plan. The Company's board of directors is
responsible for administering the Spry 1995 Plan. The options become exercisable
at a rate of 20% per year from the grant date of the options based upon the
optionee's continuous relationship with the Company. All options granted were at
a price not less that the fair market value per share of the common stock at the
time the option was granted. Upon acquisition by H&R, all options outstanding
under the Spry 1995 Plan were converted to options to purchase shares of H&R
Block delayed convertible preferred stock at a ratio of 2.09 for 1. All options
granted expire ten years from the original date they were granted.

    H&R BLOCK INCENTIVE STOCK OPTION PLAN

    Under H&R's 1995 Incentive Stock Option Plan (the "H&R Plan"), as adopted on
August 8, 1995, H&R authorized 100,000 options on H&R Block Common Shares.
Employees eligible were H&R's Internet division ("Internet Division") employees
employed prior to April 4, 1995, and were determined at the discretion of the
Internet Division executive management. The H&R Plan options

become exercisable in equal installments at the end of each of the three years
beginning on June 30, 1996.

    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123

    The Company has elected to account for its stock-based compensation plans
under APB No. 25; however, the Company has computed for pro forma disclosure
purposes the value of all options granted during the year ended April 30, 1996
using the Black-Scholes option-pricing model as prescribed by SFAS No. 123 using
the following weighted average assumptions:

<TABLE>
<S>                                                           <C>
Risk-free interest rate.....................................  5.89%
Expected dividend yield.....................................  0%
Expected lives..............................................  Three years
Expected volatility.........................................  35.32%
</TABLE>

    There were no grants in the periods ended April 30, 1997 or January 31,
1998.

    The total value of options granted during the year ended April 30, 1996 was
computed as approximately $2,356, which would be amortized on a pro forma basis
over the vesting period of the options. Additionally, there was approximately
$678 remaining unamortized compensation on grants prior to April 30, 1995. If
the Company had accounted for these plans in accordance with SFAS No. 123, the
Company's net loss and pro forma net loss for the years ended April 30, 1996 and
1997 and the nine months ended January 31, 1998 would have been as follows:

6. INCOME TAXES

    The income tax returns of its Parent Corporations have included the
operations of Spry. For purposes of these financial statements, income taxes
related to Spry have been computed and recorded on a separate return basis based
on the statutory rates in effect.

    Deferred income taxes reflect the net tax effect of temporary differences
between the carrying amount of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. The significant
components of the Company's deferred tax assets and liabilities as of April 30,
1997 and January 31, 1998 are as follows:

</TABLE>

    The company's net operating loss carryforwards (approximately $24,896 as of
January 31, 1998) will expire between 2011 and 2013 unless utilized. For the
period ended April 30, 1996, the Company's federal income tax benefit was
utilized by its Parent Corporation through a tax sharing arrangement. For all
other periods, the Company has not recognized the income tax benefit of the net
operating loss carryforwards due to the fact that its Parent Corporation was
also in a net taxable loss position and unable to utilize them. Accordingly,
management has provided a 100% valuation reserve against its net deferred tax
asset, consisting primarily of net operating loss carryforwards. In addition,
the Company's ability to recognize the benefit from the net operating loss
carryforwards could be limited under Section 382 of the Internal Revenue Code if
ownership of the Company changes more than 50%, as defined.

    A reconciliation of the income tax provision computed at statutory tax rates
to the income tax provision for the years ended April 30, 1996 and 1997 is as
follows:

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                   APRIL 30, 1996 AND 1997, JANUARY 31, 1998,
                     AND JULY 31, 1997 AND 1998 (UNAUDITED)

              (DOLLAR AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

7. EMPLOYEE BENEFIT PLAN

    The Company has a savings plan (the "Savings Plan") that qualifies as a
deferred salary arrangement under Section 401(k) of the Internal Revenue Code.
Under the Savings Plan, participating employees may defer a portion of their
pretax earnings, up to the Internal Revenue Service annual contribution limit.
Annually, the Company determines whether to make a discretionary matching
contribution equal to a percentage, determined by the Company, of the employee's
deferred compensation contribution. The Company has not made any material
matching contributions to the Savings Plan for the related periods.

8. RELATED-PARTY TRANSACTIONS

    Transactions of Spry are performed and certain management and administrative
services are executed by its Parent Corporations for the periods ending
April 30, 1996 and 1997 and January 31, 1998 respectively. Services provided to
the Company include support in major functional areas such as accounting, human
resources, legal, risk management, payroll, sales and marketing, and taxes.
Costs attributable to these support functions are included in selling, general,
and administrative expenses. These costs are allocated to Spry based on various
factors which management believes represent relative cost streams. The costs
allocated to Spry were approximately $375, $1,650, and $1,238 for the years
ended April 30, 1996 and 1997 and nine months ended January 31, 1998,
respectively.

    Spry operates under the network agreements of its Parent Corporations and
the cost of revenues for Internet services in the accompanying statement of
operations represent management's best estimate of the amounts that would have
been allocated to Spry for such services if it were a standalone entity.

    As discussed in Note 6, the Company recognized an income tax benefit of
approximately $7,693 through a tax sharing arrangement with its Parent
Corporation. This amount is reflected as a reduction in Due to/from Parent on
the accompanying balance sheet.

9. SHAREHOLDERS' (DEFICIT) EQUITY

    The Company has authorized 1,000 shares of no par value common shares, of
which 100 were outstanding for all periods.

    Prior to the AOL acquisition, Spry had outstanding 403,864 shares of
non-voting delayed convertible preferred stock (no par value), which were
convertible into shares of common stock at a ratio of four shares of common
stock to one share of preferred stock. In conjunction with the AOL acquisition
(Note 10), all such shares were retired.

10. SUBSEQUENT EVENTS (UNAUDITED)

    As discussed in Note 1, AOL acquired Spry as part of its acquisition of
CompuServe on January 31, 1998. The effect of the transaction has been pushed
down to the financial statements of the Company based upon AOL's initial
allocation of its purchase price of CompuServe and the Company.

              (DOLLAR AMOUNTS IN THOUSANDS, EXCEPT PER SHARE DATA)

10. SUBSEQUENT EVENTS (UNAUDITED) (CONTINUED)

The following table summarizes the net assets allocated to the acquisition and
the amount allocated to intangibles:

<TABLE>
<S>                                                           <C>
Purchase price..............................................  $37,500
Tangible assets acquired....................................   (6,663)
Liabilities assumed.........................................    6,525
Intangibles.................................................   37,638
</TABLE>

    This reflects a preliminary estimate of the purchase price allocations based
on management's best estimate given currently available information; however,
such information may be revised up to one year from the acquisition date.

    On September 10, 1998, MindSpring entered into an Asset Purchase Agreement
with Spry and AOL, pursuant to which, MindSpring agreed to acquire certain of
the tangible and intangible assets and rights in connection with the consumer
dial-up Internet access business currently operated by Spry as well as the
domestic and Canadian subscriber base.

    The transaction was consummated on October 15, 1998 with MindSpring paying
$25 million in cash to AOL. The final purchase price is estimated to be between
$35 million and $45 million based on final subscriber totals on various
measurement dates.

    THE TRANSACTION WILL BE COMPLETED IN THE FIRST QUARTER OF 1999, SUBJECT TO
CERTAIN CUSTOMARY CLOSING CONDITIONS.

                         NOTES TO FINANCIAL STATEMENTS

                       DECEMBER 31, 1998, 1997, AND 1996

1. ORGANIZATION

    NETCOM On-Line Communication Services, Inc. ("NETCOM" or the "Company") was
incorporated in the state of California in August 1992. In October 1994, the
Company reincorporated in the state of Delaware. In January 1998, in a
transaction accounted for as a pooling of interests, the Company became a wholly
owned subsidiary of ICG Services, Inc., a Delaware corporation, which is a
wholly owned subsidiary of ICG Communications, Inc. ("ICG"), and ceased to exist
as an independent entity. The Company provides Internet solutions to subscribers
in the United States, the United Kingdom, and Canada.

    The financial statements and related footnotes contained herein reflect the
operations of NETCOM's customer base of individual Internet access subscribers
in the United States (the "Domestic Subscriber Operations"). These amounts
exclude the results of NETCOM's operations in Canada and the United Kingdom as
well as its capital stock. A portion of the Domestic Subscriber Operations'
assets, including its subscriber base, intellectual property and facilities, is
being acquired in a transaction accounted for as a purchase by MindSpring
Enterprises, Inc. ("MindSpring"). The assets not being acquired will continue to
be utilized to provide services to MindSpring via a Network Operating Agreement
(Note 8).

    The Domestic Operations has experienced operating losses since inception as
a result of efforts to build its network infrastructure, development of its
systems, and expansion into new markets. The Domestic Operations expects to
continue to focus on increasing its subscriber base which could potentially have
a negative effect on near term results. There can be no assurance that the
Domestic Operations growth in revenue and subscriber base will continue or
exceed costs growth or that it will achieve profitability or positive cash flow.
The Domestic Operations have been funded to date by NETCOM and will be funded by
MindSpring subsequent to the acquisition.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    PRESENTATION

    The financial statements of the Domestic Subscriber Operations have been
derived from the consolidated financial statements of NETCOM and have been
prepared to present its financial position, results of operations, and cash
flows on a stand-alone basis. Accordingly, the accompanying financial statements
for 1998 only include certain administrative costs and expenses, which have been
allocated to the Domestic Subscriber Operations by NETCOM and its parent, ICG
(Note 7). These costs have been allocated on a pro rata basis based on a variety
of factors, primarily employee headcount, and represent management's best
estimates of what such expenses would have been had the Domestic Subscriber
Operations been operated as a separate entity.

    ESTIMATES AND ASSUMPTIONS

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    DUE TO PARENT

    NETCOM either advances or borrows funds from the Domestic Operations. Funds
advanced to the Domestic operations are used to cover fixed asset expansion and
working capital requirements. The source of these funds is principally the
proceeds from sales of capital stock by NETCOM. The advances and borrowings are
netted and are reflected in Due to Parent in the accompanying balance sheet.

    REVENUE RECOGNITION

    Monthly subscription service revenue is recognized over the period services
are provided. Subscription service and equipment revenues, which require the use
of company-provided installation of equipment at a subscriber's location, are
recognized when the service is commenced.

    CASH AND CASH EQUIVALENTS

    The Domestic Subscriber Operations considers all highly liquid investments
with an original maturity (at the date of purchase) of three months or less and
insignificant interest rate risk to be the equivalent of cash for the purposes
of the balance sheet presentation and statements of cash flows.

    The Domestic Subscriber Operations has classified all investments as
available-for-sale and included them in cash and cash equivalents.
Available-for-sale securities are carried at fair market value based on quoted
market prices with unrealized gains and losses reported in other income.
Interest on securities classified as available-for-sale is included in other
income. The following is a summary of available-for-sale securities at
December 31, 1998 and 1997 (in thousands):

</TABLE>

    At December 31, 1997, the estimated fair value of the commercial paper and
money market instruments approximated cost, and the amount of gross unrealized
gains and losses was not significant.

    ACCOUNTS RECEIVABLE AND DEFERRED REVENUE

    The Domestic Subscriber Operations generally bills for subscription
services, including network and dial-up connection services and initial one-time
setup fees, on the first day of each month for which service is provided.
Deferred revenue consists primarily of prepaid monthly subscriptions and also,
to a lesser extent, billings to customers for equipment shipped that has not
been installed at customer locations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    INVENTORY

    Inventory consists of purchased goods and is stated at the lower of cost or
market on a first-in, first-out basis.

    PROPERTY AND EQUIPMENT

    Property and equipment are carried at cost and are depreciated or amortized
using the straight-line method over the estimated useful life of the assets,
which are generally three to five years. Leasehold improvements are amortized
using the straight-line method over the shorter of their estimated useful lives
or the term of the related lease, whichever is shorter.

    LONG-LIVED ASSETS

    The Domestic Subscriber Operations periodically reviews the values assigned
to long-lived assets, such as property and equipment, subscriber acquisition
costs, and other long-term assets, to determine whether any impairments are
other than temporary. Management believes that the long-lived assets in the
accompanying balance sheets are appropriately valued.

    SUBSCRIBER ACQUISITION COSTS

    The Domestic Subscriber Operations expenses the costs of advertising as
incurred, except direct response advertising, which are included in subscriber
acquisition costs. These costs relate directly to subscriber solicitations and
principally include the printing, production, and shipping of starter packages
and the costs of obtaining qualified prospects by various targeted direct
marketing programs. No indirect costs are included in subscriber acquisition
costs. To date, all subscriber acquisition costs have been incurred for the
solicitation of specifically identified prospects. Subscriber acquisition costs
are deferred and amortized over a period determined by calculating the ratio of
current revenues related to the direct response advertising versus the total
expected revenues or 12 months, whichever is shorter. It is possible that these
estimates of anticipated future gross revenues could be reduced in the future.
The Domestic Subscriber Operations' management is constantly evaluating the
estimates used. As a result, the amortization period of the subscriber
acquisition costs related directly to subscriber solicitations may be reduced.

    Subscriber acquisition costs, which relate directly to potential
subscribers, are recorded separately from ordinary operating costs. Deferred
subscriber acquisition costs capitalized during fiscal years 1998 and 1997 were
$16,469 and $5,252, respectively. Amortization and write-offs for fiscal years
1998, 1997, and 1996 were $14,377, $7,189, and $11,410, respectively.

    Advertising expenses included in selling, general, and administrative
expenses were $8,268, $3,786, and $5,567 in 1998, 1997, and 1996, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    OTHER INCOME

    In June 1995, the Domestic Subscriber Operations acquired common stock in
the McKinley Group, Inc. ("McKinley") in exchange for $1,200 in cash and $300 of
common stock. In 1996, Excite, Inc. ("Excite") acquired all of the outstanding
shares of McKinley and the Domestic Subscriber Operations received shares of
Excite in exchange for its investment in McKinley. The Domestic Subscriber
Operations recorded a loss of $1,200 in 1996 to reflect the estimated value of
the shares received. During 1997, the Domestic Subscriber Operations sold the
Excite shares for a net gain of $1,274.

    SEGMENTAL DISCLOSURES

    The Domestic Subscriber Operations adopted Statement of Financial Accounting
Standards ("SFAS") No. 131, "Segmental Disclosures," effective December 31,
1998. The standard had no effect, as the Domestic Subscriber Operations operates
in one segment.

    CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subject the Domestic Subscriber
Operations to concentrations of credit risk consist principally of cash
investments and trade receivables. The Domestic Subscriber Operations' cash
investment policies limit investments to short-term, low-risk instruments.
Concentrations of credit risk with respect to trade receivables are limited due
to the large number of customers comprising the Domestic Subscriber Operations'
customer base.

    SOURCES OF SUPPLIES

    The Domestic Subscriber Operations relies on local telephone companies and
other companies to provide data communications capacity. Although management
feels that alternative telecommunications facilities could be found in a timely
manner, disruption of these services, for more than a brief period, would have
an adverse effect on operating results.

    Although the Domestic Subscriber Operations attempts to maintain multiple
vendors for each required product, its property and equipment, which are
important components of its operations, are each currently acquired from only a
few sources. In addition, some of the Domestic Subscriber Operations' suppliers
have limited resources and production capacity. If the suppliers are unable to
meet the Domestic Subscriber Operations' needs as it builds out its network
infrastructure and sells services, then delays and increased costs in the
expansion of the Domestic Subscriber Operations' network infrastructure or
losses of potential customers could result, which would adversely affect
operating results.

    INCOME TAXES

    The Domestic Operations is not a separate taxable entity. The income tax
returns of NETCOM include the Domestic Operations. For purposes of these
financial statements, income taxes allocated to

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

the Domestic Operations have been computed and recorded on a separate return
basis based on the statutory rates in effect (Note 6).

    Income taxes are accounted for under SFAS No. 109, "Accounting for Income
Taxes." Under this method, deferred tax assets and liabilities are determined
based on differences between the financial reporting and tax bases of assets and
liabilities and are measured using the enacted tax rates and laws that will be
in effect when the differences are expected to reverse.

    RECLASSIFICATIONS

    Certain prior period amounts have been reclassified to conform to the
current period presentation.

4. COMMITMENTS AND CONTINGENCIES

    LEGAL PROCEEDINGS

    The Company is subject to legal proceedings and claims that have arisen in
the ordinary course of its business related to the Domestic Subscriber
Operations. In the opinion of management, settlement of these actions when
ultimately concluded will not have a material adverse effect on trends in
results of operations or the financial condition of the Company or the Domestic
Subscriber Operations. This conclusion is based on current facts and
circumstances, however, and it is possible that a change in the facts and
circumstances relating to such legal proceedings and claims could result in a
development that would have a material adverse effect on the results of
operations or financial condition of the Domestic Subscriber Operations.

    The Domestic Subscriber Operations has been allocated leases on certain
equipment under agreements that are classified as capital leases. These leases
have original terms of three years or less and contain bargain purchase options
at the end of the original lease terms. The Domestic Subscriber Operations also
has operating leases which relate to the lease of office and equipment space.
Rental expense attributable to these operating leases was approximately $5,569,
$5,291, and $4,237 for the

    1993 STOCK OPTION PLAN

    In 1993, the Company approved and adopted its 1993 Non-qualified Stock
Option Plan (the "Plan"). The Plan is administered by the stock option committee
of the board of directors. The Plan provides for the granting of options to
purchase common stock to eligible employees, directors, and consultants of the
Company. A total of 3,153,571 shares of common stock may be issued pursuant to
options granted under the Plan. The options generally vest over three- to
five-year periods and are exercisable for up to ten years following the date of
grant.

    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123

    The option plans and 401(k) plan of NETCOM include the Domestic Operations.
For purposes of these financial statements, all option information related to
the Domestic Operations has been computed and recorded on a separate entity
basis.

    The Domestic Operations has elected to account for its stock-based

    The total value of options granted during the years ended December 31, 1998,
1997, and 1996 was computed as approximately $21,527, $39,132, and $14,199,
respectively, which would be amortized on a pro forma basis over the vesting
period of the options. If the Domestic Operations had accounted for these plans
in accordance with SFAS No. 123, the Domestic Operations net loss and pro forma
net loss for the years ended December 31, 1998, 1997, and 1996 would have been

    During 1996 and early in 1997, certain outstanding options were exchanged at
the election of the option holder. In September 1996, 67,408 shares were
exchanged and repriced for 39,995 shares, and in January 1997, 457,846 shares
were exchanged and repriced for 272,084 shares on the effective date of the
trade-in. Eligible options were issued at a lower price than the traded-in
options and at a price higher than the market value. The trade-in ratio was set
such that the number of old options times their option price approximates the
new number of options times their exercise price. This program was offered to
all employees, excluding members of the board of directors and officers of the
Company. However, option holders participating in the first exchange were not
eligible for the second program.

    ICG PLAN

    The Company's 1993 Stock Option Plan was assumed by ICG at the time of the
merger (Note 1), and approved by ICG's Board of Directors as an incentive and
non-qualified stock option plan which provides for the granting of options to
certain directors, officers and employees to purchase 2,720,901 shares of ICG
Common Stock. A total of 4,380,099 options were granted under this plan at
exercise prices ranging from $0.65 to $92.14, none of which were less than 100%
of the estimated fair market value of the shares underlying the options on the
date of grant, and accordingly, no compensation

expense was recorded for these options under APB 25. The options granted under
this plan are subject to various vesting requirements, generally three years and
five years, and expire within ten years from the date of grant.

    In order to continue to provide non-cash inventive and retain key employees,
all employee stock options outstanding on September 18, 1998 with exercise
prices at or in excess of $22.00 were canceled by the Stock Option Committee of
ICG's Board of Directos and regranted with an exercise price of $16.88. A total
of 757,058 of the Company's options, with original exercise prices ranging from
$22.02 to $35.75 where canceled and regranted.

    During fiscal 1994, Company's Board of Directors approved and adopted an
Employee Stock Purchase Plan which was dissolved upon the merger with ICG.
Shares purchased under this plan were converted into an estimated 119,000 shares
of ICG Common Stock

    EMPLOYEE SAVINGS PLAN

    The Company has a savings plan (the "Savings Plan") that qualifies as a
deferred salary arrangement under Section 401(k) of the Internal Revenue Code.
Under the Savings Plan, participating employees may defer a portion of their
pretax earnings up to the Internal Revenue Service annual contribution limit.
The Company matches 50% of each employee's contribution up to a maximum of 6% of
the employee's eligible earnings. Company matches vest over four years. The
Company has not made any material matching contributions to the Savings Plan for
the related periods.

6. INCOME TAXES

    Deferred income taxes reflect the net tax effect of temporary differences
between the carrying amount of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. As discussed in Note 2,
the Domestic Operations is not a separate legal entity, but is included in the
consolidated return of NETCOM. No tax-sharing arrangement exists between NETCOM
and the Domestic Operations, as the Domestic Operations is not a separate legal
entity. Significant components of the Domestic Subscriber Operations' allocated
deferred tax assets and

    Realization of deferred tax assets is dependent on future earnings, the
timing and amount of which are uncertain. Accordingly, a valuation allowance, in
an amount equal to the net deferred tax assets as of December 31, 1998 and 1997,
has been established to reflect these uncertainties. The change in the valuation
allowance was a net increase of $18,078 and $8,150 in 1998 and 1997,
respectively.

    As of December 31, 1998 and 1997, the Domestic Subscriber Operations portion
of NETCOM's federal and state net operating loss carryforwards was approximately
$174,678 and $125,763, respectively, which will expire in the years 1999 through
2011. In addition, the Company's ability to recognize the Domestic Subscriber
Operations' portion of the benefit from the net operating loss carryforwards
will be limited under Section 382 of the Internal Revenue Code, as the ownership
of the Company has changed more than 50%, as defined.

to the income tax provision for the years ended December 31, 1998, 1997, and

respectively. These amounts have been credited directly against due to parent,
net of a full valuation allowance.

7. RELATED-PARTY TRANSACTIONS

    Prior to the ICG merger, the Domestic Subscriber Operations' only
related-party transactions were certain cash advances to the international
operations of NETCOM. The amount of these advances at December 31, 1998 and 1997
were $38,125 and $32,352 and is included in due to parent.

    Subsequent to the merger, ICG assumed the treasury function, so that all of
the Domestic Subscriber Operations' cash at December 31, 1998 is netted in due
to parent. Additionally, ICG provided services in the area of risk management
and benefits. Estimated costs attributable to these support functions are
included in selling, general, and administrative expenses. These costs are
allocated to the Domestic Subscriber Operations based on various factors that
management believes represent relative cost streams and fair market value. The
costs allocated to the Domestic Subscriber Operations were approximately $957
for the year ended December 31, 1998.

    Following the merger, the Domestic Subscriber Operations began using certain
telecommunications services of ICG. Such amounts were $2,170 for the year ended
December 31, 1998 and are included in cost of revenue. Similarly, the Domestic
Subscriber Operations provided certain technical services to ICG. Such amounts
were $1,678 for the year ended December 31, 1998 and are included in revenues.
The rates charged for such services approximate market value in management's
opinion.

8. SUBSEQUENT EVENTS (UNAUDITED)

    On January 6, 1999, MindSpring entered into an Asset Purchase Agreement with
ICG for $215 million in cash and $30 million in MindSpring stock, pursuant to
which MindSpring agreed to acquire certain of the tangible and intangible assets
and rights in connection with the consumer dial-up Internet access business
currently operated by NETCOM as well as the Domestic Subscriber Operations'
domestic subscriber base. This agreement also contains a Network Services
Agreement for one year with an option for a second year whereby ICG will provide
MindSpring subscribers access through its points-of-presence. This transaction
will be accounted for as a purchase and is expected to be completed in the first
quarter of 1999, subject to certain customary closing conditions.

    (a) EarthLink agrees to submit this Agreement to its stockholders for
approval in accordance with SECTION 3.1 hereof.

    (b) Subject to the terms and conditions of this Agreement and the EarthLink
Certificate of Merger, at the Effective Time, immediately prior to the
MindSpring Merger (as hereinafter defined), EarthLink shall be merged with and
into Newco in accordance with the provisions of, and with the effects provided
in, Subchapter IX of the DGCL (the "EARTHLINK MERGER"). Newco shall be the
surviving corporation resulting from the EarthLink Merger, shall continue to be
governed by the laws of the State of Delaware, shall at the Effective Time amend
Article I of its Certificate of Incorporation to change its name to "EarthLink
Network, Inc.," and shall adopt the Nasdaq ticker symbol "ELNK."

    (c) Pursuant to the EarthLink Merger, each share of EarthLink Common Stock
outstanding immediately prior to the Effective Time shall be converted into and
become 1.615 shares of Newco Common Stock, and each outstanding option, warrant
and other right to purchase, or which is convertible into, EarthLink Common
Stock shall be converted into an option, warrant or other right, as the case may
be, to purchase or be convertible into a number of shares of Newco Common Stock
equal to the number of shares of EarthLink Common Stock subject to such option,
warrant or other right multiplied by 1.615 and otherwise having substantially
identical terms and conditions, except that the exercise or purchase price shall
be divided by 1.615.

    (d) Each share of EarthLink Common Stock held by EarthLink as treasury stock
or owned by MindSpring immediately prior to the Effective Time shall be
canceled.

    (e) No fraction of a share of Newco Common Stock shall be issued in
connection with the conversion of EarthLink Common Stock in the EarthLink Merger
and the distribution of Newco Common Stock in respect thereof, but in lieu of
such fraction, the Exchange Agent shall make a cash payment (without interest
and subject to the payment of any applicable withholding Taxes) equal to the
same fraction of the market value of a full share of Newco Common Stock,
computed on the basis of the mean of the high and low sales prices of Newco
Common Stock as reported on NASDAQ on the first full day on which the Newco
Common Stock is traded on the Nasdaq Stock Market after the Effective Time.

DGCL (the "MINDSPRING MERGER"). Newco shall be the surviving corporation
resulting from the MindSpring Merger and shall continue to be governed by the
laws of the State of Delaware.

    (c) Pursuant to the MindSpring Merger, each share of MindSpring Common Stock
outstanding immediately prior to the Effective Time shall be converted into and
become one (1) share of Newco Common Stock, and each outstanding option, warrant
and other right to purchase, or which is convertible into, MindSpring Common
Stock shall be converted into an option, warrant or right, as the case may be,
to purchase or be convertible into a number shares of Newco Common Stock equal
to the number of shares of Newco Common Stock subject to such option, warrant or
other right multiplied by one (1) and otherwise having substantially identical
terms and conditions, except that the exercise or purchase price shall be
divided by one (1).

    (d) Each share of MindSpring Common Stock held by MindSpring as treasury
stock or owned by EarthLink immediately prior to the Effective Time shall be
canceled.

    (e) The parties will take such action as may be necessary to cause Newco,
and Newco agrees, to execute a supplemental indenture to the MindSpring
Indenture, which shall comply with the requirements of the MindSpring Indenture,
for the purpose of assuming all of MindSpring's obligations with respect to the
MindSpring Notes, and to reserve out of its authorized Newco Common Stock a
sufficient number of shares of Newco Common Stock to permit conversion of the
MindSpring Notes on or after the Effective Time pursuant to the terms thereof
and the MindSpring Indenture.

    (f) MindSpring agrees to use its best efforts to cause the MindSpring Merger
to be consummated in accordance with the terms this Agreement of the MindSpring
Certificate of Merger.

    Section 2.3.  CANCELLATION OF NEWCO COMMON STOCK.

    Pursuant to the Mergers, the shares of Newco Common Stock held by EarthLink
and MindSpring, respectively, immediately prior to the Mergers will be canceled
in the Mergers.

    Section 2.4.  EXCHANGE OF CERTIFICATES.

    (a) Prior to the Effective Time, EarthLink and MindSpring shall cause Newco,
and Newco agrees, to appoint the Exchange Agent to act as the exchange agent in
connection with the Mergers. Except as otherwise provided in SECTION 2.1 and
SECTION 2.2, from and after the Effective Time, each holder of a certificate
that immediately prior to the Effective Time represented outstanding shares of
MindSpring Common Stock or EarthLink Common Stock (the "CERTIFICATES") shall be
entitled to receive in exchange therefor, upon surrender thereof to the Exchange
Agent, a certificate or certificates representing the number of whole shares of
Newco Common Stock into which such holder's shares

                                       8
<PAGE>
were converted in the MindSpring Merger or the EarthLink Merger, as the case may
be. Immediately prior to the Effective Time, Newco will deliver to the Exchange
Agent, in trust for the benefit of the holders of EarthLink Common Stock and
MindSpring Common Stock, (i) certificates representing shares of Newco Common
Stock and (ii) cash in an amount sufficient for payment in lieu of fractional
shares necessary to make the exchanges contemplated by SECTION 2.1 and SECTION
2.2 hereof on a timely basis.

    (b) Promptly after the Effective Time, the Exchange Agent shall mail to each
record holder of EarthLink Common Stock and MindSpring Common Stock as of the
Effective Time, a letter of transmittal (which shall specify that delivery shall
be effected, and risk of loss and title to Certificates shall pass, only upon
proper delivery of the Certificates to the Exchange Agent) and instructions for
use in effecting the surrender of Certificates in exchange for certificates
representing shares of Newco Common Stock. Upon surrender to the Exchange Agent
of a Certificate, together with such letter of transmittal duly executed, and
any other required documents, the holder of such Certificate shall be entitled
to receive in exchange therefor certificates representing shares of Newco Common
Stock as set forth in this ARTICLE II, and such Certificate shall forthwith be
canceled. No holder of a Certificate or Certificates shall be entitled to
receive any dividend or other distribution from Newco until the surrender of
such holder's Certificate for a certificate or certificates representing shares
of Newco Common Stock. Upon such surrender, there shall be paid to the holder
the amount of any dividends or other distributions (without interest) that
theretofore became payable, but that were not paid by reason of the foregoing,
with respect to the number of whole shares of Newco Common Stock represented by
the certificates issued upon surrender, which amount shall be delivered to the
Exchange Agent by Newco from time to time as such dividends or other
distributions are declared. If delivery of certificates representing shares of
Newco Common Stock is to be made to a person other than the person in whose name
the Certificate surrendered is registered or if any certificate for shares of
Newco Common Stock is to be issued in a name other than that in which the
Certificate surrendered therefor is registered, it shall be a condition of such
delivery or issuance that the Certificate so surrendered shall be properly
endorsed or otherwise in proper form for transfer and that the person requesting
such delivery or issuance shall pay any transfer or other Taxes required by
reason of such delivery or issuance to a person other than the registered holder
of the Certificate surrendered or establish to the satisfaction of Newco that
such Tax has been paid or is not applicable. Until surrendered in accordance
with the provisions of this SECTION 2.4, each Certificate shall represent for
all purposes only the right to receive shares of Newco Common Stock (and cash in
lieu of fractional shares) as provided in SECTION 2.1, and SECTION 2.2 hereto,
without any interest thereon.

    (c) After the Effective Time, there shall be no transfers on the stock
transfer books of Newco, as the surviving corporation in the Mergers, of the
shares of EarthLink Common Stock or MindSpring Common Stock that were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to Newco for transfer, they shall be canceled
and exchanged for shares of Newco Common Stock as provided in SECTION 2.1 and
SECTION 2.2 hereof, in accordance with the procedures set forth in this SECTION
2.4.

    (d) Any shares of Newco Common Stock (and any accrued dividends and
distributions thereon), and any cash held by the Exchange Agent for payment in
lieu of fractional shares, that remains unclaimed by the former stockholders of
EarthLink or MindSpring on the first anniversary of the Effective Time shall be
delivered by the Exchange Agent to Newco. Any former stockholders of EarthLink
or MindSpring who have not theretofore complied with this SECTION 2.4 shall
thereafter look only to Newco for satisfaction of their claim for the
consideration set forth in this ARTICLE II, without any interest thereon.
Notwithstanding the foregoing, Newco shall not be liable to any holder of shares
of MindSpring Common Stock or EarthLink Common Stock for any shares of Newco
Common Stock (or dividends or distributions with respect thereto) delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

Stock to Newco by Sprint Communications Company L.P. after the Effective Time,

materially impair the ability of EarthLink to consummate the transactions
contemplated by this Agreement.

    Section 5.4.  NON-CONTRAVENTION.

or (y) prevent or materially impair the ability of EarthLink to consummate the
transactions contemplated by this Agreement.

    Section 5.5.  CAPITALIZATION.

stock or other ownership interests) with such exceptions as, individually or in
the aggregate, would not be reasonably likely to have, an EarthLink Material

Material Adverse Effect, (b) any action, event, occurrence, development or state

arbitrator or Governmental Entity that, individually or in the aggregate, would
be reasonably likely to have, an EarthLink Material Adverse Effect. There are no
outstanding judgments, decrees, injunctions, awards or orders against EarthLink
that would be reasonably likely to have, individually or in the aggregate, an

    Section 5.12.  TAXES.

    (a)  All Tax returns, statements, reports and forms (collectively, the
"EARTHLINK RETURNS") required to be filed with any taxing authority by, or with
respect to, EarthLink and the EarthLink Subsidiaries have been filed in
substantial compliance with all applicable laws.

    (b)  EarthLink and the EarthLink Subsidiaries have timely paid all Taxes
shown as due and payable on the EarthLink Returns that have been so filed, and
all other Taxes not subject to reporting obligations, and, as of the time of
filing, the EarthLink Returns correctly reflected the facts regarding the
income, business, assets, operations, activities and the status of EarthLink and
the EarthLink Subsidiaries (other than Taxes that are being contested in good
faith and for which adequate reserves are reflected on the EarthLink Balance
Sheet).

    (c)  EarthLink and the EarthLink Subsidiaries have made provision for all
Taxes payable by them for which no EarthLink Return has yet been filed.

    (d)  The charges, accruals and reserves for Taxes with respect to EarthLink
and the EarthLink Subsidiaries reflected on the EarthLink Balance Sheet are
adequate under GAAP to cover the tax liabilities accruing through the date
thereof.

    (e)  There is no action, suit, proceeding, audit or claim now proposed or
pending against or with respect to EarthLink or any of the EarthLink
Subsidiaries in respect of any Tax that would be reasonably likely to have an
EarthLink Material Adverse Effect

    (f)  Neither EarthLink nor any of the EarthLink Subsidiaries has been a
member of an affiliated, consolidated, combined or unitary group other than one
of which EarthLink was the common parent.

    (g)  Neither EarthLink nor any of the EarthLink Subsidiaries holds any asset
subject to a consent under Section 341(f) of the Code.

    Section 5.13.  EMPLOYEE BENEFITS.

    (a)  SECTION 5.13(A) of the EarthLink Disclosure Schedule contains a correct
and complete list identifying each material "employee benefit plan", as defined
in Section 3(3) of the Employee Retirement Income Security Act of 1974
("ERISA"), each employment, severance or similar contract, plan, arrangement or
policy and each other plan or arrangement (written or oral) providing for
compensation, bonuses, profit-sharing, stock option or other stock related
rights or other forms of incentive or deferred compensation, vacation benefits,
insurance coverage (including any self-insured arrangements), health or medical
benefits, disability benefits, workers' compensation, supplemental

                                       16
<PAGE>
unemployment benefits, severance benefits and post-employment or retirement
benefits (including compensation, pension, health, medical or life insurance
benefits) that is maintained, administered or contributed to by EarthLink or any
ERISA Affiliate (as defined below) and covers any employee or former employee of
EarthLink or any EarthLink Subsidiary. Copies of such plans (and, if applicable,
related trust agreements) and all amendments thereto and written interpretations
thereof have been furnished, or will be made available upon request, to
MindSpring together with the most recent annual report (Form 5500 including, if
applicable, Schedule B thereto) prepared in connection with any such plan. Such
plans are referred to collectively herein as the "EARTHLINK EMPLOYEE PLANS". For
purposes of this SECTION 5.13, "ERISA AFFILIATE" of any Person means any other
Person which, together with such Person, would be treated as a single employer
under Section 414 of the Code.

    (b)  SCHEDULE 5.13(B) of the EarthLink Disclosure Schedule separately
identifies each EarthLink Employee Plan that constitutes a "multiemployer plan",
as defined in Section 3(37) of ERISA (a "MULTIEMPLOYER PLAN"), or any other plan
subject to Title IV of ERISA (a "RETIREMENT PLAN"). No "accumulated funding
deficiency", as defined in Section 412 of the Code, has been incurred with
respect to any EarthLink Employee Plan that is a Retirement Plan, whether or not
waived. To the Knowledge of EarthLink, no condition exists and no event has
occurred that would be reasonably likely to constitute grounds for termination
of any EarthLink Employee Plan that is a Retirement Plan or, with respect to any
EarthLink Employee Plan that is a Multiemployer Plan, presents a material risk
of a complete or partial withdrawal under Title IV of ERISA and neither
EarthLink nor any of its ERISA Affiliates has incurred any liability under Title
IV of ERISA arising in connection with the termination of, or complete or
partial withdrawal from, any plan covered or previously covered by Title IV of
ERISA that would be reasonably likely to have an EarthLink Material Adverse
Effect. To the Knowledge of EarthLink, nothing has been done or omitted to be
done and no transaction or holding of any asset under or in connection with any
EarthLink Employee Plan has occurred that will make EarthLink or any EarthLink
Subsidiary, or any officer or director of EarthLink or any EarthLink Subsidiary,
subject to any liability under Title I of ERISA or liable for any tax pursuant
to Section 4975 of the Code (assuming the taxable period of any such transaction
expired as of the date hereof) that would be reasonably likely to have an
EarthLink Material Adverse Effect.

    (c)  Each EarthLink Employee Plan that is intended to be qualified under
Section 401 (a) of the Code is so qualified and has been so qualified during the
period from its adoption to date, and each trust forming a part thereof is
exempt from tax pursuant to Section 501(a) of the Code. EarthLink has furnished,
or will make available upon request, to MindSpring copies of the most recent
Internal Revenue Service determination letters with respect to each such
EarthLink Employee Plan. Each EarthLink Employee Plan has been maintained in
substantial compliance with its terms and with the requirements prescribed by
any and all statutes, orders, rules and regulations, including but not limited
to ERISA and the Code, which are applicable to such EarthLink Employee Plan.

    (d)  There is no contract, agreement, plan or arrangement that, as a result
of the EarthLink Merger, would be reasonably likely to obligate EarthLink to
make any payment of any amount that would not be deductible pursuant to the
terms of Section 162(m) or Section 280G of the Code.

    (e)  Except as disclosed in writing to MindSpring prior to the date hereof,
there has been no amendment to, written interpretation or announcement (whether
or not written) relating to, or change in employee participation or coverage
under, any EarthLink Employee Plan that would increase materially the expense of
maintaining such EarthLink Employee Plan above the level of the expense incurred
in respect thereof for the fiscal year ended December 31, 1998.

    (f)  No EarthLink Employee Plan promises or provides post-retirement
medical, life insurance or other benefits due now or in the future to current,
former or retired employees of EarthLink or any subsidiary.

    Section 5.14.  COMPLIANCE WITH LAWS; LICENSES, PERMITS AND REGISTRATIONS.

    (a)  To the Knowledge of EarthLink, neither EarthLink nor any EarthLink
Subsidiary is in violation of, or has violated, any applicable provisions of any
laws, statutes, ordinances, regulations, judgments, injunctions, orders or
consent decrees, except for any such violations that, individually or in the
aggregate, would not be reasonably likely to have an EarthLink Material Adverse
Effect.

    (b)  Each of EarthLink and the EarthLink Subsidiaries has all permits,
licenses, approvals, authorizations of and registrations with and under all
federal, state, local and foreign laws, and from all Governmental Entities
required by EarthLink and the EarthLink Subsidiaries to carry on their
respective businesses as currently conducted, except where the failure to have
any such permits, licenses, approvals, authorizations or registrations,
individually or in the aggregate, would not be reasonably likely to have an
EarthLink Material Adverse Effect.

    Section 5.15.  TITLE TO PROPERTIES.

    (a)  EarthLink and each EarthLink Subsidiary have good and marketable title
to, or valid leasehold interests in, all their properties and assets except for
such as are no longer used or useful in the conduct of their businesses or as
have been disposed of in the ordinary course of business and except for defects
in title, easements, restrictive covenants and similar Liens, encumbrances or
impediments that, in the aggregate, do not materially interfere with the ability
of EarthLink and its Subsidiaries to conduct their business, taken as a whole,
as currently conducted. All such assets and properties, other than assets and
properties in which EarthLink or any EarthLink Subsidiary has leasehold
interests, are free and clear of all Liens, except for Liens that, in the
aggregate, do not and will not materially interfere with the ability of
EarthLink and the EarthLink Subsidiaries to conduct their business, taken as a
whole, as currently conducted.

    (b)  Except as would not be reasonably likely, individually or in the
aggregate, to have an EarthLink Material Adverse Effect, (i) EarthLink and each
EarthLink Subsidiary are in compliance with the terms of all leases to which
they are a party and under which they are in occupancy, and all such leases are
in full force and effect and (ii) EarthLink and each EarthLink Subsidiary enjoy
peaceful and undisturbed possession under all such leases.

    Section 5.16.  INTELLECTUAL PROPERTY.

    Except as would not be reasonably likely to have an EarthLink Material
Adverse Effect or a Newco Material Adverse Effect, individually or in the
aggregate, EarthLink and the EarthLink Subsidiaries own or have a valid license
to use each trademark, service mark, trade name, mask work, invention, patent,
trade secret, copyright, know-how (including any registrations or applications
for registration of any of the foregoing) or any other similar type of
proprietary intellectual property right (collectively, the "EARTHLINK
INTELLECTUAL PROPERTY") necessary to carry on the business of EarthLink and the
EarthLink Subsidiaries, taken as a whole, as currently conducted or as proposed
to be conducted by Newco. Neither EarthLink nor any EarthLink Subsidiary has
received any written notice of infringement of or challenge to, and there are no
claims pending or, to EarthLink's Knowledge, threatened with respect to the
rights of others to the use of, any EarthLink Intellectual Property that, in any
such case, individually or in the aggregate, would be reasonably likely to have
an EarthLink Material Adverse Effect or a Newco Material Adverse Effect.

    Section 5.17.  ENVIRONMENTAL MATTERS.

    (a)  With such exceptions as, individually or in the aggregate, would not be
reasonably likely to have an EarthLink Material Adverse Effect, to the Knowledge
of EarthLink, (i) no written notice, notification, demand, request for
information, citation, summons, complaint or order has been received by, and no
investigation, action, claim, suit, proceeding or review is pending or
threatened by any Person against EarthLink or any EarthLink Subsidiary with
respect to any applicable Environmental

                                       18
<PAGE>
Law and (ii) EarthLink and the EarthLink Subsidiaries are and have been in
compliance with all applicable Environmental Laws.

    (b)  For purposes of this SECTION 5.17 and SECTION 6.17, the term
"ENVIRONMENTAL LAWS" means any federal, state, local and foreign statutes, laws
(including, without limitation, common law), judicial decisions, regulations,
ordinances, rules, judgments, orders, codes, injunctions, permits or
governmental agreements relating to human health and safety, the environment or
to pollutants, contaminants, wastes, or chemicals.

    Section 5.18.  FINDERS' FEES; OPINIONS OF FINANCIAL ADVISOR.

    (a)  Except for Credit Suisse First Boston Corporation, there is no
investment banker, broker, finder or other intermediary that has been retained
by, or is authorized to act on behalf of, EarthLink or any EarthLink Subsidiary
who might be entitled to any fee or commission from MindSpring or any of its
Affiliates upon consummation of the transactions contemplated by this Agreement.

    (b)  EarthLink has received the opinion of Credit Suisse First Boston
Corporation, dated as of the date hereof, to the effect that, as of such date,
the EarthLink Exchange Ratio is fair, from a financial point of view, to the
holders of shares of EarthLink Common Stock and EarthLink Preferred Stock (other
than MindSpring and any MindSpring Subsidiary).

    Section 5.19.  REQUIRED VOTE, BOARD APPROVAL.

    (a)  The only votes of the holders of any class or series of capital stock
of EarthLink required by law, rule or regulation to approve this Agreement
and/or any of the other transactions contemplated hereby are the affirmative
vote of the holders of more than fifty percent of the outstanding EarthLink
Common Stock (the "EARTHLINK STOCKHOLDER APPROVAL").

    (b)  EarthLink's Board of Directors has unanimously (i) determined that this
Agreement and the transactions contemplated hereby, including the EarthLink
Merger, are advisable and in the best interests of EarthLink and its
stockholders, (ii) approved this Agreement and the transactions contemplated
hereby and (iii) resolved to recommend to such stockholders that they vote in
favor of adopting and approving this Agreement in accordance with the terms
hereof.

    Section 5.20.  STATE TAKEOVER STATUTES.

    EarthLink has taken all actions required to be taken by it in order to
exempt this Agreement and the transactions contemplated hereby from the
provisions of Section 203 of the DGCL, and accordingly, such Sections do not
apply to the EarthLink Merger or any of such transactions. No other "control
share acquisition," "fair price" or other anti-takeover laws or regulations
enacted under state or federal laws in the United States apply to this Agreement
or any of the transactions contemplated hereby.

    Section 5.21.  POOLING MATTERS; TAX TREATMENT.

    (a)  EarthLink intends that the EarthLink Merger be accounted for under the
"pooling of interests" method under the requirements of Opinion No. 16 (Business
Combinations) of the Accounting Principles Board of the American Institute of
Certified Public Accountants, the Financial Accounting Standards Board, and the
rules and regulations of the SEC. EarthLink will request a letter addressed to
it from PricewaterhouseCoopers LLP dated as of the Closing Date, and (if and
when obtained) a copy of it will be delivered to MindSpring. Such letter (which
may contain customary qualifications and assumptions) shall state that
PricewaterhouseCoopers LLP concurs with EarthLink's management's conclusion that
no conditions exist that would preclude Newco from accounting for the Mergers as
a "pooling of interests," as described in the first sentence of this
SECTION 5.21(A).

    (b)  Neither EarthLink nor any of its Affiliates has taken or agreed to
take, or will take, any action or is aware of any fact or circumstance that
would prevent the EarthLink Merger from qualifying (i) for "pooling of
interests" accounting treatment as described in SECTION 5.21(A) above or
(ii) as a 368 Reorganization.

    Section 5.22.  CERTAIN AGREEMENTS.

    None of EarthLink, any EarthLink Subsidiary or any of their respective
Affiliates (i) are parties to or otherwise bound by any agreement or arrangement
that limits or otherwise restricts EarthLink, any EarthLink Subsidiary or Newco
or any of their respective Affiliates from engaging or competing in any line of
business or in any locations, which agreement or arrangement is material to the
business of EarthLink and the EarthLink Subsidiaries or would be material to the
business of Newco (assuming the Mergers had taken place), in either case taken
as a whole and (ii) except in the ordinary course of business, have amended,
modified or terminated any material contract, agreement or arrangement of
EarthLink or any EarthLink Subsidiary or otherwise waived, released or assigned
any material rights, claims or benefits of EarthLink or any EarthLink Subsidiary
thereunder.

    Section 5.23.  YEAR 2000 COMPLIANCE.

    EarthLink has reviewed its operations and has made reasonable inquiries of
any third parties with which EarthLink has a material relationship to evaluate
the extent to which the business or operations of EarthLink will be affected by
the Year 2000 Problem. As a result of such review, except as otherwise described
in the EarthLink SEC documents, EarthLink has no reason to believe, and does not
believe, that the Year 2000 Problem will have an EarthLink Material Adverse
Effect or result in any material loss or interference with EarthLink's business
or operations. The "Year 2000 Problem" as used herein means any significant risk
that computer hardware or software used in the receipt, transmission,
processing, manipulation, storage, retrieval, retransmission or other
utilization of data or in the operation of mechanical or electrical systems of
any kind will not, in the case of dates or time periods occurring after
December 31, 1999, function at least as effectively as in the case of dates or
time periods occurring prior to January 1, 2000.

                  REPRESENTATIONS AND WARRANTIES OF MINDSPRING

    Except as disclosed in (i) the MindSpring Disclosure Schedule delivered to
EarthLink separately prior to, or contemporaneously with, the date hereof (which
disclosure schedule shall make a specific reference to the particular Section or
subsection of this Agreement to which exception is being taken but once made

(ii) the MindSpring SEC Documents filed or made prior to the date hereof,
MindSpring represents and warrants to EarthLink that:

    Section 6.1.  CORPORATE EXISTENCE AND POWER.

    MindSpring is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Delaware, and has all corporate powers
required to carry on its business as now conducted. MindSpring is duly qualified
to do business as a foreign corporation and is in good standing in each
jurisdiction where the character of the property owned or leased by it or the
nature of its activities makes such qualification necessary, except where the
failure to be so qualified, individually or in the aggregate, would not be
reasonably likely to have an MindSpring Material Adverse Effect. MindSpring has
heretofore made available to EarthLink true and complete copies of MindSpring's
certificate of incorporation and bylaws as currently in effect.

    Section 6.2.  CORPORATE AUTHORIZATION.

    The execution, delivery and performance by MindSpring of this Agreement and
the consummation by MindSpring of the transactions contemplated hereby are
within MindSpring's corporate powers and, except for the MindSpring Stockholder
Approval (as defined herein), have been duly authorized by all necessary
corporate action. Assuming that this Agreement constitutes the valid and binding
obligation of EarthLink and Newco, this Agreement constitutes a valid and
binding agreement of MindSpring,

                                       20
<PAGE>
enforceable in accordance with its terms, subject to bankruptcy, insolvency,
reorganization, moratorium and similar laws, now or hereafter in effect,
relating to or affecting creditors' rights and remedies and to general
principles of equity.

    Section 6.3.  GOVERNMENTAL AUTHORIZATION.

    The execution, delivery and performance by MindSpring of this Agreement and
the consummation by MindSpring of the transactions contemplated hereby require
no action by or in respect of, or filing with, any Governmental Entity other
than (a) the filing of (i) a certificate of merger in accordance with the DGCL
and (ii) appropriate documents with the relevant authorities of other states or
jurisdictions in which MindSpring or any MindSpring Subsidiary is qualified to
do business; (b) compliance with any applicable requirements of the HSR Act;
(c) compliance with any applicable requirements of the Securities Act and the
Exchange Act; (d) such as may be required under any applicable state securities
or blue sky laws; and (e) such other consents, approvals, actions, orders,
authorizations, registrations, declarations and filings that, if not obtained or
made, would not, individually or in the aggregate, (x) be reasonably likely to
have a MindSpring Material Adverse Effect or (assuming for this purpose that the
Effective Time had occurred) an EarthLink Material Adverse Effect, or
(y) prevent or materially impair the ability of MindSpring to consummate the
transactions contemplated by this Agreement.

    Section 6.4.  NON-CONTRAVENTION.

    The execution, delivery and performance by MindSpring of this Agreement and
the consummation by MindSpring of the transactions contemplated hereby do not
and will not (a) contravene or conflict with MindSpring's certificate of
incorporation or bylaws, (b) assuming compliance with the matters referred to in
SECTION 6.3, contravene or conflict with or constitute a violation of any
provision of any law, regulation, judgment, injunction, order or decree binding
upon or applicable to MindSpring or any MindSpring Subsidiary, (c) constitute a
default under or give rise to a right of termination, cancellation or
acceleration of any right or obligation of MindSpring or any MindSpring
Subsidiary or to a loss of any benefit or status to which MindSpring or any
MindSpring Subsidiary is entitled under any provision of any agreement, contract
or other instrument binding upon MindSpring or any MindSpring Subsidiary or any
license, franchise, permit or other similar authorization held by MindSpring or
any MindSpring Subsidiary, or (d) result in the creation or imposition of any
Lien on any asset of MindSpring or any MindSpring Subsidiary other than, in the
case of each of (b), (c) and (d), any such items that would not, individually or
in the aggregate (x) be reasonably likely to have a MindSpring Material Adverse
Effect or (y) prevent or materially impair the ability of MindSpring to
consummate the transactions contemplated by this Agreement.

    Section 6.5.  CAPITALIZATION.

    (a) The authorized capital stock of MindSpring consists of 400,000,000
shares of MindSpring Common Stock and 1,000,000 shares of MindSpring Preferred
Stock. As of September 21, 1999, there were outstanding (x) 63,504,352 shares of
MindSpring Common Stock, (y) no shares of MindSpring Preferred Stock and
(z) stock options to purchase an aggregate of 5,542,579 shares of MindSpring
Common Stock (of which options to purchase an aggregate of 1,054,346 MindSpring
Common Stock were exercisable). All outstanding shares of capital stock of
MindSpring have been duly authorized and validly issued and are fully paid and
nonassessable.

    (b) As of the date hereof, except (i) as set forth in this SECTION 6.5,
(ii) the MindSpring Notes and (iii) for changes since September 21, 1999,
resulting from the exercise of stock options outstanding on such date, there are
no outstanding (x) shares of capital stock or other voting securities of
MindSpring, (y) securities of MindSpring convertible into or exchangeable for
shares of capital stock or voting securities of MindSpring, or (z) options or
other rights to acquire from MindSpring, and no obligation of MindSpring to
issue, any capital stock, voting securities or securities convertible into or
exchangeable for capital stock or voting securities of MindSpring (the items in
clauses (x), (y) and (z) being referred

                                       21
<PAGE>
to collectively as the "MINDSPRING SECURITIES"). If a Change of Control, as
defined in the MindSpring Indenture, had occurred as of September 21, 1999, the
MindSpring Notes would have been convertible into 2,879,600 shares o MindSpring
Common Stock. There are no outstanding obligations of MindSpring or any
MindSpring Subsidiary to repurchase, redeem or otherwise acquire any MindSpring
Securities. There are no outstanding contractual obligations of MindSpring to
provide funds to, or make any investment (in the form of a loan, capital
contribution or otherwise) in, any other Person other than in the ordinary
course of business consistent with past practice. There are no stockholder
agreements, voting trusts or other agreements or understandings to which
MindSpring is a party, or of which MindSpring is aware, relating to voting,
registration or disposition of any shares of capital stock of MindSpring or
granting to any person or group of persons the right to elect, or to designate
or nominate for election, a director to the board of directors of MindSpring.

    (b) As of its filing date, each MindSpring SEC Document complied as to form

and/or the Exchange Act, as the case may be.

    (c) No MindSpring SEC Document filed pursuant to the Exchange Act contained,
as of its filing date, any untrue statement of a material fact or omitted to
state any material fact necessary in order to make the statements made therein,
in the light of the circumstances under which they were made, not misleading. No
MindSpring SEC Document, as amended or supplemented, if applicable, filed
pursuant to the Securities Act contained, as of the date such document or
amendment became effective, any untrue statement of a material fact or omitted
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading.

    Section 6.8.  FINANCIAL STATEMENTS, NO MATERIAL UNDISCLOSED LIABILITIES.

    (a) The audited financial statements and unaudited interim financial
statements of MindSpring included in the MindSpring 10-K and the MindSpring 10-Q
fairly present in all material respects, in conformity with GAAP (except as may
be indicated in the notes thereto and except that financial statements on
Form 10-Q do not contain all GAAP notes to such financial statements), the
financial position of MindSpring and its Subsidiaries as of the dates thereof
and their results of operations and changes in financial position for the
periods then ended (subject to normal year-end adjustments in the case of any
unaudited interim financial statements).

any kind whatsoever, whether accrued, contingent, absolute, determined,
determinable or otherwise, in each case, that are required by GAAP to be set

    connection with the transactions contemplated hereby; and

        (iii) other liabilities or obligations that individually or in the
    aggregate, would not be reasonably likely to have a MindSpring Material
    Adverse Effect.

    Section 6.9.  INFORMATION TO BE SUPPLIED.

    (a) The information to be supplied by MindSpring expressly for inclusion or
incorporation by reference in the Joint Proxy Statement/Prospectus will (i) in
the case of the Registration Statement, at the time it becomes effective, not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein not misleading and (ii) in the case of the remainder of the Joint Proxy
Statement/Prospectus, at the time of the mailing thereof, and at the time of the
Special Meetings, not contain any untrue statement of a material fact or omit to

respects with the provisions of the Securities Act and the Exchange Act.

    (b) Notwithstanding the foregoing, MindSpring makes no representation or
warranty with respect to any statements made or incorporated by reference in the

Newco.

    Section 6.10.  ABSENCE OF CERTAIN CHANGES.

    Since December 31, 1998, except as otherwise expressly contemplated by this
Agreement, MindSpring and the MindSpring Subsidiaries have conducted their
business in the ordinary course consistent with past practice and there has not

by insurance) affecting the business or assets of MindSpring or any MindSpring
Subsidiary that, individually or in the aggregate, has had or would be
reasonably likely to have a MindSpring Material Adverse Effect, (b) any action,
event, occurrence, development or state of circumstances or facts that,
individually or in the aggregate, has had or would be reasonably likely to have
a MindSpring Material Adverse Effect or (c) any incurrence, assumption or
guarantee by MindSpring of any material indebtedness for borrowed money other
than in the ordinary course and in amounts and on terms consistent with past
practices.

    Section 6.11.  LITIGATION.

    There is no action, suit, investigation, arbitration or proceeding pending
against, or to the Knowledge of MindSpring threatened against, MindSpring or any
MindSpring Subsidiary or any of their respective assets or properties before any
arbitrator or Governmental Entity that, individually or in the aggregate, would
be reasonably likely to have a MindSpring Material Adverse Effect. There are no
outstanding judgments, decrees, injunctions, awards or orders against MindSpring
that would be reasonably likely to have, individually or in the aggregate, a
MindSpring Material Adverse Effect.

    Section 6.12.  TAXES.

    (a) All Tax returns, statements, reports and forms (collectively, the
"MINDSPRING RETURNS") required to be filed with any taxing authority by, or with
respect to, MindSpring and the MindSpring Subsidiaries have been filed in
substantial compliance with all applicable laws.

    (b) MindSpring and the MindSpring Subsidiaries have timely paid all Taxes
shown as due and payable on the MindSpring Returns that have been so filed, and

filing, the MindSpring Returns correctly reflected the facts regarding the
income, business, assets, operations, activities and the status of MindSpring
and the MindSpring Subsidiaries (other than Taxes that are being contested in
good faith and for which adequate reserves are reflected on the MindSpring
Balance Sheet).

    (c) MindSpring and the MindSpring Subsidiaries have made provision for all
Taxes payable by them for which no MindSpring Return has yet been filed.

                                       23
<PAGE>
    (d) The charges, accruals and reserves for Taxes with respect to MindSpring
and its Subsidiaries reflected on the MindSpring Balance Sheet are adequate
under GAAP to cover the Tax liabilities accruing through the date thereof.

    (e) There is no action, suit, proceeding, audit or claim now proposed or
pending against or with respect to MindSpring or any of the MindSpring
Subsidiaries in respect of any Tax that would be reasonably likely to have a
MindSpring Material Adverse Effect.

    (f) Neither MindSpring nor any of the MindSpring Subsidiaries has been a
member of an affiliated, consolidated, combined or unitary group other than one
of which MindSpring was the common parent.

    (g) Neither MindSpring nor any of the MindSpring Subsidiaries holds any
asset subject to a consent under Section 341(f) of the Code.

    Section 6.13.  EMPLOYEE BENEFITS.

    (a) SECTION 6.13(A) of the MindSpring Disclosure Schedule contains a correct
and complete list identifying each material "employee benefit plan", as defined
in Section 3(3) of the ERISA, each employment, severance or similar contract,
plan, arrangement or policy and each other plan or arrangement (written or oral)
providing for compensation, bonuses, profit-sharing, stock option or other stock
related rights or other forms of incentive or deferred compensation, vacation
benefits, insurance coverage (including any self-insured arrangements), health
or medical benefits, disability benefits, workers' compensation, supplemental
unemployment benefits, severance benefits and post-employment or retirement
benefits (including compensation, pension, health, medical or life insurance
benefits) that is maintained, administered or contributed to by MindSpring or
any ERISA Affiliate and covers any employee or former employee of MindSpring or
any MindSpring Subsidiary. Copies of such plans (and, if applicable, related
trust agreements) and all amendments thereto and written interpretations thereof
have been furnished, or will be made available upon request, to EarthLink
together with the most recent annual report (Form 5500 including, if applicable,
Schedule B thereto) prepared in connection with any such plan. Such plans are
referred to collectively herein as the "MINDSPRING EMPLOYEE PLANS".

    (b) SECTION 6.13(B) of the MindSpring Disclosure Schedule separately
identifies each MindSpring Employee Plan that constitutes a Multiemployer Plan
or a Retirement Plan. No "accumulated funding deficiency", as defined in
Section 412 of the Code, has been incurred with respect to any MindSpring
Employee Plan that is a Retirement Plan, whether or not waived. To the Knowledge
of MindSpring, no condition exists and no event has occurred that would be
reasonably likely to constitute grounds for termination of any MindSpring
Employee Plan that is a Retirement Plan or, with respect to any MindSpring
Employee Plan that is a Multiemployer Plan, presents a material risk of a
complete or partial withdrawal under Title IV of ERISA and neither MindSpring
nor any of its ERISA Affiliates has incurred any liability under Title IV of
ERISA arising in connection with the termination of, or complete or partial
withdrawal from, any plan covered or previously covered by Title IV of ERISA
that would be reasonably likely to have a MindSpring Material Adverse Effect. To
the Knowledge of MindSpring, nothing has been done or omitted to be done and no
transaction or holding of any asset under or in connection with any MindSpring
Employee Plan has occurred that will make MindSpring or any MindSpring
Subsidiary, or any officer or director of MindSpring or any MindSpring
Subsidiary, subject to any liability under Title I of ERISA or liable for any
tax pursuant to Section 4975 of the Code (assuming the taxable period of any
such transaction expired as of the date hereof) that would be reasonably likely
to have a MindSpring Material Adverse Effect.

    (c) Each MindSpring Employee Plan that is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period from its adoption to date, and each trust forming a part thereof is
exempt from tax pursuant to Section 501(a) of the Code. MindSpring

                                       24
<PAGE>
has furnished, or will make available upon request, to EarthLink copies of the
most recent Internal Revenue Service determination letters with respect to each
such MindSpring Employee Plan. Each MindSpring Employee Plan has been maintained
in substantial compliance with its terms and with the requirements prescribed by
any and all statutes, orders, rules and regulations, including but not limited
to ERISA and the Code, which are applicable to such MindSpring Employee Plan.

    (d) There is no contract, agreement, plan or arrangement that, as a result
of the MindSpring Merger, would be reasonably likely to obligate MindSpring to
make any payment of any amount that would not be deductible pursuant to the
terms of Section 162(m) or Section 280G of the Code.

    (e) Except as disclosed in writing to EarthLink prior to the date hereof,
there has been no amendment to, written interpretation or announcement (whether
or not written) relating to, or change in employee participation or coverage
under, any MindSpring Employee Plan that would increase materially the expense
of maintaining such MindSpring Employee Plan above the level of the expense
incurred in respect thereof for the fiscal year ended December 31, 1998.

    (f) No MindSpring Employee Plan promises or provides post-retirement
medical, life insurance or other benefits due now or in the future to current,
former or retired employees of MindSpring or any subsidiary.

    Section 6.14.  COMPLIANCE WITH LAWS; LICENSES, PERMITS AND REGISTRATIONS.

    (a) To the Knowledge of MindSpring, neither MindSpring nor any MindSpring
Subsidiary is in violation of, or has violated, any applicable provisions of any
laws, statutes, ordinances, regulations, judgments, injunctions, orders or
consent decrees, except for any such violations that, individually or in the
aggregate, would not be reasonably likely to have a MindSpring Material Adverse
Effect.

    (b) Each of MindSpring and the MindSpring Subsidiaries has all permits,
licenses, approvals, authorizations of and registrations with and under all
federal, state, local and foreign laws, and from all Governmental Entities
required by MindSpring and the MindSpring Subsidiaries to carry on their
respective businesses as currently conducted, except where the failure to have
any such permits, licenses, approvals, authorizations or registrations,
individually or in the aggregate, would not be reasonably likely to have a
MindSpring Material Adverse Effect.

    Section 6.15.  TITLE TO PROPERTIES.

    (a) MindSpring and each MindSpring Subsidiary have good and marketable title
to, or valid leasehold interests in, all their properties and assets except for
such as are no longer used or useful in the conduct of their businesses or as
have been disposed of in the ordinary course of business and except for defects
in title, easements, restrictive covenants and similar Liens, encumbrances or
impediments that, in the aggregate, do not materially interfere with the ability
of MindSpring and its Subsidiaries to conduct their business, taken as a whole,
as currently conducted. All such assets and properties, other than assets and
properties in which MindSpring or any MindSpring Subsidiary has leasehold
interests, are free and clear of all Liens, except for Liens that, in the
aggregate, do not and will not materially interfere with the ability of
MindSpring and the MindSpring Subsidiaries to conduct their business, taken as a
whole, as currently conducted.

    (b) Except as would not be reasonably likely, individually or in the
aggregate, to have a MindSpring Material Adverse Effect, (i) MindSpring and each
MindSpring Subsidiary are in compliance with the terms of all leases to which
they are a party and under which they are in occupancy, and all such leases are
in full force and effect and (ii) MindSpring and each MindSpring Subsidiary
enjoy peaceful and undisturbed possession under all such leases.

                                       25
<PAGE>
    Section 6.16.  INTELLECTUAL PROPERTY.

    Except as would not be reasonably likely to have a MindSpring Material
Adverse Effect or a Newco Material Adverse Effect, individually or in the
aggregate, MindSpring and the MindSpring Subsidiaries own or have a valid
license to use each trademark, service mark, trade name, mask work, invention,
patent, trade secret, copyright, know-how (including any registrations or
applications for registration of any of the foregoing) or any other similar type
of proprietary intellectual property right (collectively, the "MINDSPRING
INTELLECTUAL PROPERTY") necessary to carry on the business of MindSpring and the
MindSpring Subsidiaries, taken as a whole, as currently conducted or as proposed
to be conducted by Newco. Neither MindSpring nor any MindSpring Subsidiary has
received any written notice of infringement of or challenge to, and there are no
claims pending or, to MindSpring's Knowledge, threatened with respect to the
rights of others to the use of, any MindSpring Intellectual Property that, in
any such case, individually or in the aggregate, would be reasonably likely to
have a MindSpring Material Adverse Effect or a Newco Material Adverse Effect.

    Section 6.17.  ENVIRONMENTAL MATTERS.

    With such exceptions as, individually or in the aggregate, would not be
reasonably likely to have a MindSpring Material Adverse Effect, to the Knowledge
of MindSpring, (i) no written notice, notification, demand, request for
information, citation, summons, complaint or order has been received by, and no
investigation, action, claim, suit, proceeding or review is pending or
threatened by any Person against, MindSpring or any MindSpring Subsidiary, with
respect to any applicable Environmental Law and (ii) MindSpring and the
MindSpring Subsidiaries are and have been in compliance with all applicable
Environmental Laws.

    Section 6.18.  FINDERS' FEES; OPINIONS OF FINANCIAL ADVISOR.

    (a) Except for Donaldson, Lufkin & Jenrette Securities Corporation, there is
no investment banker, broker, finder or other intermediary that has been
retained by, or is authorized to act on behalf of, MindSpring or any MindSpring
Subsidiary who might be entitled to any fee or commission from EarthLink or any
of its Affiliates upon consummation of the transactions contemplated by this
Agreement.

    (b) MindSpring has received the opinion of Donaldson, Lufkin & Jenrette
Securities Corporation, dated as of the date hereof, to the effect that, as of
such date, the MindSpring Exchange Ratio is fair, from a financial point of
view, to the holders of shares of MindSpring Common Stock (other than EarthLink
and any EarthLink Subsidiary).

    Section 6.19.  REQUIRED VOTE, BOARD APPROVAL.

    (a) The only vote of the holders of any class or series of capital stock of
MindSpring required by law, rule or regulation to approve this Agreement and/or
any of the other transactions contemplated hereby is the affirmative vote (the
"MINDSPRING STOCKHOLDER APPROVAL") of the holders of more than fifty percent of
the outstanding shares of MindSpring Common Stock in favor of the adoption of
this Agreement.

    (b) MindSpring's Board of Directors has unanimously (i) determined that this
Agreement and the transactions contemplated hereby, including the MindSpring
Merger, are advisable and in the best interests of MindSpring and its
stockholders, (ii) approved this Agreement and the transactions contemplated
hereby and (iii) resolved to recommend to such stockholders that they vote in
favor of adopting and approving this Agreement in accordance with the terms
hereof.

    Section 6.20.  STATE TAKEOVER STATUTES.

    MindSpring has taken all actions required to be taken by it in order to
exempt this Agreement and the transactions contemplated hereby from the
provisions of Section 203 of the DGCL, and

                                       26
<PAGE>
accordingly, such Sections do not apply to the Merger or any of such
transactions. No other "control share acquisition," "fair price" or other
anti-takeover laws or regulations enacted under state or federal laws in the
United States apply to this Agreement or any of the transactions contemplated
hereby.

    Section 6.21.  POOLING MATTERS; TAX TREATMENT.

    (a) MindSpring intends that the MindSpring Merger be accounted for under the
"pooling of interests" method under the requirements of Opinion No. 16 (Business
Combinations) of the Accounting Principles Board of the American Institute of
Certified Public Accountants, the Financial Accounting Standards Board, and the
rules and regulations of the SEC. MindSpring will request a letter addressed to
it from Arthur Andersen LLP dated as of the Closing Date, and (if and when
obtained) a copy of it will be delivered to EarthLink. Such letter (which may
contain customary qualifications and assumptions) shall state that Arthur
Andersen LLP concurs with MindSpring's management's conclusion that no
conditions exist with respect to MindSpring that would preclude Newco from
accounting for the Mergers as a "pooling of interests" as described in the first
sentence of SECTION 6.21(A).

    (b) Neither MindSpring nor any of its Affiliates has taken or agreed to
take, or will take, any action or is aware of any fact or circumstance that
would prevent the MindSpring Merger from qualifying (i) for "pooling of
interests" accounting treatment as described in SECTION 6.21(A) above or
(ii) as a 368 Reorganization.

    Section 6.22.  CERTAIN AGREEMENTS.

    None of MindSpring, any MindSpring Subsidiary or any of their respective
Affiliates (i) are parties to or otherwise bound by any agreement or arrangement
that limits or otherwise restricts MindSpring, any MindSpring Subsidiary or
Newco or any of their respective Affiliates from engaging or competing in any
line of business or in any locations, which agreement or arrangement is material
to the business of MindSpring and the MindSpring Subsidiaries or would be
material to the business of Newco (assuming the Mergers had taken place), in
either case taken as a whole and (ii) except in the ordinary course of business,
have amended, modified or terminated any material contract, agreement or
arrangement of MindSpring or any MindSpring Subsidiary or otherwise waived,
released or assigned any material rights, claims or benefits of MindSpring or
any MindSpring Subsidiary thereunder.

    Section 6.23.  YEAR 2000 COMPLIANCE.

    MindSpring has reviewed its operations and has made reasonable inquiries of
any third parties with which MindSpring has a material relationship to evaluate
the extent to which the business or operations of MindSpring will be affected by
the Year 2000 Problem. As a result of such review, except as otherwise described
in the MindSpring SEC documents, MindSpring has no reason to believe, and does
not believe, that the Year 2000 Problem will have an MindSpring Material Adverse
Effect or result in any material loss or interference with MindSpring's business
or operations.

                                  ARTICLE VII
                             COVENANTS OF EARTHLINK

    EarthLink agrees that:

    Section 7.1.  EARTHLINK INTERIM OPERATIONS.

    Except as set forth in the EarthLink Disclosure Schedule or as otherwise
expressly contemplated hereby, without the prior consent of MindSpring (which

Subsidiaries to, conduct their business in all material respects in the ordinary

MindSpring (which consent shall not be unreasonably withheld or delayed),
EarthLink shall not, nor shall it permit any EarthLink Subsidiary to:

exercise of stock options or warrants in accordance with their present terms or
upon exercise of options issued pursuant to clause (A) above of this
SECTION 7.1(C)(I); or (C) EarthLink Common Stock upon the conversion of the

MindSpring, or (ii) incurred in the ordinary course of business of EarthLink and
the EarthLink Subsidiaries;

    (e) acquire (whether pursuant to cash merger, stock or asset purchase or
otherwise) in one transaction or series of related transactions (i) any assets

<PAGE>
or rights to acquire any debt securities of EarthLink or any EarthLink
Subsidiary or guarantee any debt securities of others, except in the ordinary
course of business consistent with past practice (which shall include, without
limitation, borrowings under EarthLink's existing credit agreements and
overnight borrowings); PROVIDED, HOWEVER, that, notwithstanding the foregoing
neither EarthLink nor any EarthLink Subsidiary shall incur any borrowings
whatsoever under the Credit Agreement dated as of February 10, 1998, between
EarthLink, as borrower, and Sprint, as lender;

    (h) (i) enter into any agreement or arrangement that limits or otherwise
restricts EarthLink, any EarthLink Subsidiary or any of their respective
Affiliates or any successor thereto or that would, after the Effective Time,
limit or restrict EarthLink, any EarthLink Subsidiary or Newco, or any of their
respective Affiliates, from engaging or competing in any line of business or in

    (k) (i) settle, or propose to settle, any litigation, investigation,

most recent consolidated financial statements (or the notes thereto) of
EarthLink included in the EarthLink SEC Documents or (y) incurred since the date
of such financial statements in the ordinary course of business consistent with
past practice, or (ii) other than in the ordinary course of business consistent
with past practice, make any tax election or enter into any settlement or
compromise of any tax liability that in either case is material to the business

    Section 7.2.  ACQUISITION PROPOSALS; BOARD RECOMMENDATION.

    (a) EarthLink agrees that it shall not, nor shall it permit any EarthLink
Subsidiary to, nor shall it authorize or knowingly permit any officer, director,
employee, investment banker, attorney, accountant, agent or other advisor or
representative of EarthLink or any EarthLink Subsidiary, directly or indirectly,
to (i) solicit, initiate or knowingly facilitate or encourage the submission of
any Acquisition Proposal for EarthLink, (ii) participate in any discussions or
negotiations regarding, or furnish to any Person any information with respect to
or take any other action knowingly to facilitate any inquiries or the making of
any proposal that constitutes an Acquisition Proposal for EarthLink,
(iii) grant any waiver or release under any standstill or similar agreement with
respect to any class of EarthLink's equity securities or (iv) enter into any
agreement with respect to an Acquisition Proposal for

                                       29
<PAGE>
EarthLink. Without limiting the foregoing, it is understood that any violation
of the restrictions set forth in the preceding sentence by any officer,
director, investment banker, attorney, accountant, agent or other advisor or
representative of EarthLink or any EarthLink Subsidiary, whether or not such
individual is purporting to act on behalf of EarthLink or any EarthLink
Subsidiary or otherwise, shall be deemed to be a breach of this SECTION 7.2 by
EarthLink. EarthLink shall cease and cause to be terminated immediately all
existing discussions or negotiations with any Persons conducted heretofore with
respect to, or that could be reasonably expected to lead to, any Acquisition
Proposal for EarthLink.

    (b) Notwithstanding the foregoing, nothing contained in this SECTION 7.2
shall prohibit the Board of Directors of EarthLink from (i) to the extent
applicable, complying with Rules 14d-9 and 14e-2 promulgated under the Exchange
Act with regard to an Acquisition Proposal for EarthLink; and (ii) prior to the
EarthLink Special Meeting, furnishing information to or entering into
discussions or negotiations with, any Person that makes a BONA FIDE proposal or
offer with respect to EarthLink that constitutes an Acquisition Proposal for
EarthLink, if (A) the Board of Directors of EarthLink determines in good faith,
taking into account the advice of outside counsel, that such action is
reasonably likely to be required for the Board of Directors to comply with its
fiduciary duties to stockholders under applicable law; (B) prior to furnishing
such information to, or entering into discussions or negotiations with, such
Person, EarthLink provides written notice to MindSpring of the identity of the
Person making the Acquisition Proposal for EarthLink and that it intends to
furnish information to, or intends to enter into discussions or negotiations
with, such Person; (C) EarthLink enters into a confidentiality agreement with
such Person on terms in the aggregate not more favorable to such Person than the
terms of the letter agreement, dated August 17, 1999, between EarthLink and
MindSpring; (D) EarthLink keeps MindSpring informed on a timely basis of the
status of such negotiations and all material terms and conditions thereof and
promptly provides MindSpring with copies of any and all written inquiries or
proposals relating thereto; and (E) such Acquisition Proposal was not solicited
in violation of SECTION 7.2(A) hereof.

    (c) Notwithstanding any other provision of this Agreement, in the event that
an Acquisition Proposal for EarthLink constitutes an EarthLink Superior Proposal
(as defined below), the Board of Directors of EarthLink may withdraw its
recommendation of this Agreement as required under SECTION 3.1 hereof and
recommend such EarthLink Superior Proposal to its stockholders (i) if, but only
if, EarthLink (A) complies fully with this SECTION 7.2 and (B) provides
MindSpring with at least four (4) Business Days' prior written notice of its
intent to withdraw its recommendation of this Agreement and (ii) if, in the
event that during such four (4) Business Days MindSpring makes a counter
proposal to such EarthLink Superior Proposal (the "MINDSPRING COUNTER
PROPOSAL"), the EarthLink Board of Directors in good faith, taking into account
the advice of its outside financial advisors, determines that the MindSpring
Counter Proposal is not at least as favorable to EarthLink's stockholders as the
EarthLink Superior Proposal (taking into account all financial and strategic
considerations and other relevant factors, including relevant legal, financial,
regulatory and other aspects of such proposals, and the conditions, prospects
and time required for completion of such proposal).

    (d) For the purposes of this Agreement, an "EARTHLINK SUPERIOR PROPOSAL"
means a BONA FIDE Acquisition Proposal, having no financing contingency, for
more than seventy-five percent (75%) of the aggregate voting power of the
EarthLink Equity Securities and made by a Person other than an affiliate of
EarthLink that the Board of Directors of EarthLink believes in good faith,
(x) taking into account the advice of its outside financial advisors, to be
superior, from a financial point of view, to the stockholders of EarthLink than
the proposal set forth in this Agreement and (y) to be more favorable generally
to the stockholders of EarthLink (taking into account all financial and
strategic considerations and other relevant factors, including relevant legal,
financial, regulatory and other aspects of such proposals, and the conditions,
prospects and time required for completion of such proposal); PROVIDED THAT the
Board of Directors of EarthLink has determined in good faith, taking into
account the advice

                                       30
<PAGE>
of its outside legal counsel, that it is reasonably likely to be required to
recommend such proposal to the EarthLink stockholders to comply with its
fiduciary duties to stockholders under applicable law.

    (e) For the purposes of this Agreement, "EARTHLINK EQUITY SECURITIES" means
(i) any EarthLink common stock; (ii) any EarthLink preferred stock; (iii) any
debt or equity securities of EarthLink convertible into or exchangeable for
EarthLink common stock or preferred stock (on a fully-converted basis); and
(iv) any options, warrants or rights (or any other similar securities) issued by
EarthLink to acquire EarthLink common stock or preferred stock (on a
fully-converted basis).

    (f) Nothing in this SECTION 7.2 shall (i) permit EarthLink to terminate this
Agreement (except as specifically provided in ARTICLE XI hereof) or (ii) affect
any other obligation of EarthLink under this Agreement.

                                  ARTICLE VIII
                            COVENANTS OF MINDSPRING

    MindSpring agrees that:

    Section 8.1.  MINDSPRING INTERIM OPERATIONS.

    Except as set forth in the MindSpring Disclosure Schedule or as otherwise
expressly contemplated hereby, without the prior consent of EarthLink (which
consent shall not be unreasonably withheld or delayed), from the date hereof

the ordinary course consistent with past practice and shall use commercially
reasonable efforts to (i) preserve intact its present business organization,

approvals and authorizations, including, without limitation, all material
licenses and permits that are required for MindSpring or any MindSpring
Subsidiary to carry on its business and (iii) preserve existing relationships
with its material customers, lenders, suppliers and others having material
business relationships with it. Without limiting the generality of the
foregoing, except as otherwise expressly contemplated by this Agreement, from
the date hereof until the Effective Time, without the prior consent of EarthLink

not, not shall it permit any MindSpring Subsidiary to:

    (a) amend its certificate of incorporation or by-laws;

    (b) split, combine or reclassify any shares of capital stock of MindSpring
or any less-than-wholly-owned MindSpring Subsidiary or declare, set aside or pay

combination thereof) in respect of its capital stock or redeem, repurchase or
otherwise acquire or offer to redeem, repurchase, or otherwise acquire any of
its securities or any securities of any MindSpring Subsidiary;

    (c) (i) issue, deliver or sell, or authorize the issuance, delivery or sale
of, any shares of its capital stock of any class or any securities convertible

    Section 8.2.  ACQUISITION PROPOSALS; BOARD RECOMMENDATION.

    (a) MindSpring agrees that it shall not, nor shall it permit any MindSpring
Subsidiary to, nor shall it authorize or knowingly permit any officer, director,
employee, investment banker, attorney, accountant, agent or other advisor or
representative of MindSpring or any MindSpring Subsidiary, directly or
indirectly, to (i) solicit, initiate or knowingly facilitate or encourage the
submission of any Acquisition Proposal for MindSpring, (ii) participate in any
discussions or negotiations regarding, or furnish to any Person any information
with respect to, or take any other action knowingly to facilitate any inquiries
or the making of any proposal that constitutes an Acquisition Proposal for
MindSpring, (iii) grant any waiver or release under any standstill or similar
agreement with respect to any class of MindSpring equity securities or
(iv) enter into any agreement with respect to any Acquisition Proposal for
MindSpring. Without limiting the foregoing, it is understood that any violation
of the restrictions set forth in the preceding sentence by any officer,
director, investment banker, attorney, accountant, agent or other advisor or
representative of MindSpring or any MindSpring Subsidiary, whether or not such
individual is purporting to act on behalf of MindSpring or any MindSpring
Subsidiary, or otherwise, shall be deemed to be a breach of this SECTION 8.2 by
MindSpring. MindSpring shall cease and cause to be terminated immediately all
existing discussions or negotiations with any Persons conducted heretofore with
respect to, or that could be reasonably expected to lead to, any Acquisition
Proposal for MindSpring.

    (b) Notwithstanding the foregoing, nothing contained in this SECTION 8.2
shall prohibit the Board of Directors of MindSpring from (i) to the extent
applicable, complying with Rules 14d-9 and 14e-2 promulgated under the Exchange
Act with regard to an Acquisition Proposal for MindSpring; and (ii) prior to the
MindSpring Special Meeting, furnishing information to or entering into
discussions or negotiations with, any Person that makes a bona fide proposal or
offer with respect to MindSpring that constitutes an Acquisition Proposal for
MindSpring, if: (A) the Board of Directors of MindSpring determines in good
faith, taking into account the advice of outside counsel, that such action is
reasonably likely to be required for the Board of Directors to comply with its
fiduciary duties to stockholders under applicable law; (B) prior to furnishing
such information to, or entering into discussions or negotiations with, such
Person, MindSpring provides written notice to EarthLink of the identity of the
Person making the Acquisition Proposal for MindSpring and that it intends to
furnish information to, or intends to enter into discussions or negotiations
with, such Person; (C) MindSpring enters into a confidentiality agreement with
such Person on terms in the aggregate not more favorable to such Person than the
terms of the letter agreement, dated August 17, 1999, between MindSpring and
EarthLink; (D) MindSpring keeps EarthLink informed on a timely basis of the
status of such negotiations and all material terms and conditions thereof and
promptly provides EarthLink with copies of any and all written inquiries or
proposals relating thereto; and (E) such Acquisition Proposal was not solicited
in violation of SECTION 8.2(A).

    (c) Notwithstanding any other provision of this Agreement, in the event that
an Acquisition Proposal for MindSpring constitutes a MindSpring Superior
Proposal (as defined below), the Board of Directors of MindSpring may withdraw
its recommendation of this Agreement as required under SECTION 3.1 hereof and
recommend such MindSpring Superior Proposal to its stockholders (i) if, but only
if, MindSpring (A) complies fully with this SECTION 8.2 and (B) provides
EarthLink with at least four (4) Business Days' prior written notice of its
intent to withdraw its recommendation of this

                                       33
<PAGE>
Agreement and (ii) if, in the event that during such four (4) Business Days
EarthLink makes a counter proposal to such MindSpring Superior Proposal (the
"EARTHLINK COUNTER PROPOSAL"), the MindSpring Board of Directors in good faith,
taking into account the advice of its outside financial advisors, determines
that the EarthLink Counter Proposal is not at least as favorable to MindSpring's
stockholders as the MindSpring Superior Proposal (taking into account all
financial and strategic considerations and other relevant factors, including
relevant legal, financial, regulatory and other aspects of such proposals, and
the conditions, prospects and time required for completion of such proposal).

    (d) For the purposes of this Agreement, a "MINDSPRING SUPERIOR PROPOSAL"
means a BONA FIDE Acquisition Proposal, having no financing contingency, for
more than seventy-five percent (75%) of the aggregate voting power of the
MindSpring Equity Securities and made by a Person other than an affiliate of
MindSpring that the Board of Directors of MindSpring believes in good faith,
(x) taking into account the advice of its outside financial advisors, to be
superior, from a financial point of view, to the stockholders of MindSpring than
the proposal set forth in this Agreement and (y) to be more favorable generally
to the stockholders of MindSpring (taking into account all financial and
strategic considerations and other relevant factors, including relevant legal,
financial, regulatory and other aspects of such proposals, and the conditions,
prospects and time required for completion of such proposal); PROVIDED THAT the
Board of Directors of MindSpring has determined in good faith, taking into
account the advice of its outside legal counsel, that it is reasonably likely to
be required to recommend such proposal to the MindSpring stockholders to comply
with its fiduciary duties to stockholders under applicable law.

    (e) For the purposes of this Agreement, "MINDSPRING EQUITY SECURITIES"
means: (i) any MindSpring common stock; (ii) any MindSpring preferred stock;
(iii) any debt or equity securities of MindSpring convertible into or
exchangeable for MindSpring common stock or preferred stock (on a
fully-converted basis); and (iv) any options, warrants or rights (or any other
similar securities) issued by MindSpring to acquire MindSpring common stock or
preferred stock (on a fully-converted basis).

    (f) Nothing in this SECTION 8.2 shall (i) permit MindSpring to terminate
this Agreement (except as specifically provided in ARTICLE XI hereof) or
(ii) affect any other obligation of MindSpring under this Agreement.

                                   ARTICLE IX
                  COVENANTS OF MINDSPRING, NEWCO AND EARTHLINK

    The parties hereto agree that:

    Section 9.1.  REASONABLE BEST EFFORTS.

    Subject to the terms and conditions hereof, each party will use reasonable
best efforts to take, or cause to be taken, all actions and to do, or cause to
be done, all things necessary, proper or advisable under applicable laws and
regulations to consummate the transactions contemplated by this Agreement as
promptly as practicable. In furtherance of the parties' undertakings pursuant to
this SECTION 9.1, the parties shall cooperate in good faith to take such actions
as they deem necessary to satisfy the closing conditions set forth in
SECTION 10.2(D) hereof.

    Section 9.2.  CERTAIN FILINGS; COOPERATION IN RECEIPT OF CONSENTS; LISTING.

    Promptly after the date hereof, MindSpring, EarthLink and Newco shall
prepare and Newco shall file with the SEC the Registration Statement, in which
the Joint Proxy Statement/Prospectus will be included as Newco's prospectus.
Each of MindSpring and EarthLink shall use all reasonable efforts to have the
Registration Statement declared effective under the Securities Act as promptly
as practicable after such filing and to keep the Registration Statement
effective as long as is necessary to consummate

                                       34
<PAGE>
the Mergers. Each of MindSpring and EarthLink shall mail the Joint Proxy

and, if necessary, after the Joint Proxy Statement/Prospectus shall have been so
mailed, promptly circulate amended, supplemental or supplemented proxy material,
and, if required in connection therewith, resolicit proxies. EarthLink and
MindSpring shall cause Newco to take any action required to be taken under any
applicable state securities or blue sky laws in connection with the issuance of
shares of Newco Common Stock in the Mergers.

    (a) No amendment or supplement to the Joint Proxy Statement/Prospectus will
be made by Newco, MindSpring or EarthLink without the approval of the other
parties, which will not be unreasonably withheld or delayed. Each party will
advise the other parties, promptly after it receives notice thereof, of (i) the
time when the Registration Statement has become effective or any supplement or
amendment has been filed, (ii) the issuance of any stop order, (iii) the
suspension of the qualification of the shares of Newco Common Stock issuable in
connection with the Mergers for offering or sale in any jurisdiction, or
(iv) any request by the SEC for amendment of the Joint Proxy
Statement/Prospectus or comments thereon and responses thereto or requests by
the SEC for additional information. If at any time prior to the Effective Time,
MindSpring or EarthLink discovers any information relating to either party, or
any of their respective Affiliates, officers or directors, that should be set
forth in an amendment or supplement to the Joint Proxy Statement/Prospectus, so
that such document would not include any misstatement of a material fact or omit
to state any material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading, the party that
discovers such information shall promptly notify the other parties hereto and an
appropriate amendment or supplement describing such information shall be
promptly filed with the SEC and, to the extent required by law or regulation,
disseminated to the stockholders of MindSpring or EarthLink.

    (b) MindSpring and EarthLink shall cooperate with one another in
(i) determining whether any other action by or in respect of, or filing with,
any Governmental Entity is required, or any actions, consents, approvals or
waivers are required to be obtained from parties to any material contracts, in
connection with the consummation of the transactions contemplated hereby,
(ii) seeking any such other actions, consents, approvals or waivers or making
any such filings, furnishing information required in connection therewith and
seeking promptly to obtain any such actions, consents, approvals or waivers and
(iii) setting a mutually acceptable date for the Special Meetings, so as to
enable them to occur, to the extent practicable, on the same date. Each party
shall permit the other party to review any communication given by it to, and
consult with each other in advance of any meeting or conference with, any
Governmental Entity or, in connection with any proceeding by a private party,
with any other Person, and to the extent permitted by the applicable
Governmental Entity or other Person, give the other party the opportunity to
attend and participate in such meetings and conferences, in each case in
connection with the transactions contemplated hereby.

    (c) Newco, EarthLink and MindSpring agree to use their respective reasonable
best efforts to cause the shares of Newco Common Stock to be issued upon
conversion of shares of EarthLink Common Stock and MindSpring Common Stock in
accordance with this Agreement and the Certificates of Merger to be approved for
listing upon issuance on the Nasdaq Stock Market with the ticker symbol "ELNK."

    Section 9.3.  PUBLIC ANNOUNCEMENTS.

    The parties shall consult with each other before issuing any press release
or making any public statement with respect to this Agreement and the
transactions contemplated hereby and, except as may be required by applicable
law or any listing agreement with any national securities exchange association,
will not issue any such press release or make any such public statement prior to
such consultation.

advisors, auditors and other authorized representatives such financial and
operating data and other information as such Persons may reasonably request and
(iii) instruct its employees, counsel, financial advisors, auditors and other
authorized representatives to cooperate with the reasonable requests of the
other party in its investigation. Any investigation pursuant to this
SECTION 9.4 shall be conducted in such manner as not to interfere unreasonably
with the conduct of the business of the other party. Unless otherwise required
by law, each of EarthLink and MindSpring will hold, and will cause its
respective officers, employees, counsel, financial advisors, auditors and other
authorized representatives to hold, any nonpublic information obtained in any
such investigation in confidence in accordance with SECTION 9.8. No information
or knowledge obtained in any investigation pursuant to this SECTION 9.4 shall
affect or be deemed to modify any representation or warranty made by any party
hereunder.

    (b) Each party hereto shall give prompt notice to each other party hereto
of:

        (i) any communication received by such party from, or given by such
    party to, any Governmental Entity in connection with any of the transactions
    contemplated hereby; and

        (ii) any actions, suits, claims, investigations or proceedings commenced
    or, to its Knowledge, threatened against, relating to or involving or
    otherwise affecting such party or any of its Subsidiaries that, if pending
    on the date of this Agreement, would have been required to have been
    disclosed pursuant to this Agreement or that relate to the consummation of
    the transactions contemplated by this Agreement

PROVIDED, HOWEVER, that the delivery of any notice pursuant to this
SECTION 9.4(B) shall not limit or otherwise affect the remedies available
hereunder to the party receiving such notice.

    Section 9.5.  FURTHER ASSURANCES.

    At and after the Effective Time, the officers and directors of Newco will be
authorized to execute and deliver, in the name and on behalf of EarthLink or
MindSpring, any deeds, bills of sale, assignments or assurances and to take and
do, in the name and on behalf of EarthLink or MindSpring, any other actions and
things to vest, perfect or confirm of record or otherwise in Newco any and all
right, title and interest in, to and under any of the rights, properties or
assets of MindSpring or EarthLink acquired or to be acquired by Newco as a
result of, or in connection with the Mergers.

    Section 9.6.  TAX AND ACCOUNTING TREATMENT.

    (a) Prior to the Effective Time, each party shall use its best efforts to
cause each of the Mergers to qualify as a 368 Reorganization, and will not take
any action reasonably likely to cause the Mergers not so to qualify. Newco shall
not take any action after the Effective Time reasonably likely to cause either
of the Mergers not to qualify as a 368 Reorganization.

    (b) Each party will use its best efforts to cause the Mergers to qualify for
"pooling of interest" accounting treatment as described in SECTION 5.21 and
SECTION 6.21, and will not take any action reasonably likely to cause the
Mergers not so to qualify.

    (c) Each party shall use its best efforts to obtain the opinions referred to
in SECTION 10.1(F).

    Section 9.7.  AFFILIATE LETTERS.

    (a) Within 30 days following the date hereof, EarthLink shall cause to be
delivered to Newco a letter identifying, to the best of EarthLink's Knowledge,
all Persons who may be deemed to be

                                       36
<PAGE>
"affiliates" of EarthLink for purposes of Rule 145(c) under the Securities Act.
EarthLink shall use commercially reasonable efforts to cause each such Person
who is so identified to deliver to Newco on or prior to the Effective Time a
letter agreement substantially in the form of EXHIBIT 11-A to this Agreement.

    (b) Within 30 days following the date hereof, MindSpring shall cause to be
delivered to Newco a letter identifying, to the best of MindSpring's Knowledge,
all Persons who may be deemed to be "affiliates" of MindSpring for purposes of
Rule 145(c) under the Securities Act. MindSpring shall use commercially
reasonable efforts to cause each such Person who is so identified to deliver to
Newco on or prior to the Effective Time a letter agreement substantially in the
form of EXHIBIT 11-B to this Agreement.

    Section 9.8.  CONFIDENTIALITY.

    (a) Prior to the Effective Time and after any termination of this Agreement
each party hereto will hold, and will use its best efforts to cause its
officers, directors, employees, accountants, counsel, consultants, advisors,
affiliates (as such term is used in Rule 12b-2 under the Exchange Act) and
representatives (collectively, the "REPRESENTATIVES"), to hold, in confidence
all confidential documents and information concerning the other parties hereto
and the Subsidiaries furnished to such party in connection with the transactions
contemplated by this Agreement, including, without limitation, all analyses,
compilations, studies or records prepared by the party receiving the information
or by such party's Representatives, that contain or otherwise reflect or are
generated from such information (collectively, the "CONFIDENTIAL MATERIAL"). The
party furnishing any Confidential Material is herein referred to as the
"DELIVERING COMPANY" and the party receiving any Confidential Material is herein
referred to as the "RECEIVING COMPANY."

    (b) The Receiving Company agrees that the Confidential Material will not be
used other than for the purpose of the transaction contemplated by this
Agreement, and that such information will be kept confidential by the Receiving
Company and its Representatives; provided, however, that (i) any of such
information may be disclosed to the Representatives who need to know such
information for the purpose described above (it being understood that (a) each
such Representative shall be informed by the Receiving Company of the
confidential nature of such information, shall be directed by the Receiving
Company to treat such information confidentially and not to use it other than
for the purpose described above and shall agree to be bound by the terms of this
SECTION 9.8, and (b) in any event, the Receiving Company shall be responsible
for any breach of this Agreement by any of its Representatives), and (ii) any
other disclosure of such information may be made if the Delivering Company has,
in advance, consented to such disclosure in writing. The Receiving Company will
make all reasonable, necessary and appropriate efforts to safeguard the
Confidential Material from disclosure to anyone other than as permitted hereby.

    (c) Notwithstanding the foregoing, if the Receiving Company or any of its
Representatives is requested or required (by oral question or request for
information or documents in legal proceedings, interrogatories, subpoena, civil
investigative demand or similar process) to disclose any Confidential Material,
the Receiving Company will promptly notify the Delivering Company of such
request or requirement so that the Delivering Company may seek an appropriate
protective order and/or waive the Receiving Company's compliance with the
provisions or this Agreement. If, in the absence of a protective order or the
receipt of a waiver hereunder, the Receiving Company or any of its
Representatives is nonetheless, in the reasonable written opinion of the
Receiving Company's counsel, compelled to disclose Confidential Material to any
tribunal, the Receiving Company or such Representative, after notice to the
Delivering Company, may disclose such information to such tribunal. The
Receiving Party shall exercise reasonable efforts to obtain reliable assurance
that confidential treatment will be accorded the Confidential Material so
disclosed. The Receiving Company or such Representative shall not be liable for
the disclosure of Confidential Material hereunder to a tribunal

                                       37
<PAGE>
compelling such disclosure unless such disclosure to such tribunal was caused by
or resulted from a previous disclosure by the Receiving Company or any of its
Representatives not permitted by this Agreement.

    (d) This SECTION 9.8 shall be inoperative as to particular portions of the
Confidential Material if such information (i) is or becomes generally available
to the public other than as a result of a disclosure by the Receiving Company or
its Representatives, (ii) was available to the Receiving Company on a
non-confidential basis prior to its disclosure to the Receiving Company by the
Delivering Company or the Delivering Company's Representatives, or
(iii) becomes available to the Receiving Company on a non-confidential basis
from a source other than the Delivering Company or the Delivering Company's
Representatives, provided that such source is not known by the Receiving
Company, after reasonable inquiry, to be bound by a confidentiality agreement
with the Delivering Company or the Delivering Company's Representatives and is
not otherwise prohibited from transmitting the information to the Receiving
Company by a contractual, legal or fiduciary obligation. The fact that
information included in the Confidential Material is or becomes otherwise
available to the Receiving Company or its Representatives under clauses
(i) through (iii) above shall not relieve the Receiving Company or its
Representatives of the prohibitions of the confidentiality provisions of this
SECTION 9.8 with respect to the balance of the Confidential Material.

    (e) If this Agreement is terminated, each party hereto will, and will use
its best efforts to cause its officers, directors, employees, accountants,
counsel, consultants, advisors and agents to, destroy or deliver to the party
from whom such Confidential Material was obtained, upon request, all documents
and other materials, and all copies thereof, obtained by such party or on its
behalf from any such other parties in connection with this Agreement that are
subject to such confidence.

    Section 9.9.  MINDSPRING STANDSTILL.

    If this Agreement is terminated, then, for two years after the date of such
termination, MindSpring and each of its successors or assigns will not, and will

    Affiliates or any direct rights or options to acquire (through purchase,
    exchange, conversion or otherwise) any assets or in excess of 5% of any
    class of securities of EarthLink or its Affiliates;

        (ii) make, or in any way participate in, directly or indirectly, any
    "solicitation" of "proxies" (as such terms are defined in Rule 14a-1 of
    Regulation 14A promulgated by the SEC as of the date hereof, disregarding
    clause (iv) of Rule 14a-1(1)(2), but including any solicitation exempted
    pursuant to Rule 14a-2(b)(1) to vote (including by the execution of actions
    by written consent)), or seek to advise, encourage or influence any person
    or entity with respect to the voting of, any voting securities of EarthLink;

        (iii) call, or in any way participate in a call for, any meeting of
    stockholders of EarthLink (or take any action with respect to stockholders

    meaning of Section 13(d)(3) of the Exchange Act) with respect to any voting

        (v) effect or seek, offer or propose (whether publicly or otherwise) to
    effect, cause or participate in or in any way assist any other Person to
    effect or seek, offer or propose (whether publicly or otherwise) to effect
    or participate in any tender or exchange offer or merger or other business
    combination involving EarthLink or any EarthLink Subsidiary; or

        (vi) otherwise act, alone or in concert, to control or influence, or
    seek to control or influence, EarthLink or the management, Board of
    Directors, policies or affairs of EarthLink, including

                                       38
<PAGE>
    without limitation, (A) making any offer or proposal to acquire any
    securities or assets of EarthLink or any of its Affiliates or soliciting or
    proposing to effect or negotiate any form of business combination,
    restructuring, recapitalization or other extraordinary transaction involving
    EarthLink, its Affiliates or any of their respective securities or assets,
    (B) seeking board representation or the removal of any directors or a change
    in the composition or size of the Board of Directors of EarthLink,
    (C) making any request to amend or waive any provision of this SECTION 9.9,
    including, without limitation, this SUBSECTION (C), (D) disclosing any
    intent, purpose, plan or proposal with respect to matters covered by this
    SECTION 9.9 or EarthLink, its Affiliates or the boards of directors,
    management, policies or affairs or securities or assets of EarthLink or its
    Affiliates that is inconsistent with this SECTION 9.9, including an intent,
    purpose, plan or proposal that is conditioned on, or would require, waiver,
    amendment, nullification or invalidation of any provision of this
    SECTION 9.9; or take any action that could require EarthLink or any of its
    Affiliates to make any public disclosure relating to any such intent,
    purpose, plan, proposal or condition, or (E) assisting, advising or
    encouraging any person with respect to, or seeking to do, any of the
    foregoing;

PROVIDED, HOWEVER, that this SECTION 9.9 shall not apply if EarthLink does not
pay any portion of the Termination Fee when due or if MindSpring terminates this
Agreement as a result of a willful breach of this Agreement by EarthLink;
PROVIDED, FURTHER, that, if this SECTION 9.9 is effective against MindSpring
(and each of its successors and their respective Affiliates) during any such
two-year period after the date of any such termination, and either
(x) EarthLink shall have entered into an agreement with respect to any
transaction that constitutes an Acquisition Proposal for EarthLink (assuming for
this purpose that this Agreement had been effective at such time) for at least a

Agreement as a result of a willful breach of this Agreement by MindSpring;
PROVIDED, FURTHER, that, if this SECTION 9.10 is effective against EarthLink
(and each of its successors and their respective Affiliates) during any such

or (y) any Person or "GROUP" (as defined in Section 13(d)(3) of the Exchange
Act) (other than MindSpring or any of its Affiliates, excluding, for this
purpose, MindSpring's management acting independently of MindSpring)) shall have
commenced any tender or exchange offer that constitutes an Acquisition Proposal
of MindSpring (assuming for this purpose that this Agreement had been effective
at such time) for at least a majority of the voting securities of MindSpring
then outstanding which offer is recommended by MindSpring's Board of Directors
to its stockholders, then at the time of the public announcement of such
agreement or of the commencement of such offer, as applicable, this

be no rights, liabilities or obligations under this SECTION 9.10 on the part of
EarthLink, MindSpring, Newco or any of their respective officers, directors,
stockholders, agents or Affiliates.

    Section 9.11.  ASR 135.

    Newco shall use its best efforts to publish as promptly as reasonably
practical, but in no event later than 90 days after the end of the first month
after the Effective Time in which there are at least 30 days of post-Mergers
combined operations (which month may be the month in which the Effective

                                       40
<PAGE>
Time occurs), combined sales and net income figures as contemplated by and in
accordance with the terms of SEC Accounting Series Release No. 135.

    Section 9.12.  BENEFIT MATTERS.

    EarthLink and MindSpring will work together to design benefit plans to be
adopted by Newco for the benefit of its employees as soon as practicable
following the Mergers. Until such adoption, Newco shall cause all EarthLink
Employee Plans and all MindSpring Employee Plans to be maintained in full force
and effect.

    Section 9.13.  ANTITRUST MATTERS.

    (a) The parties hereto promptly will complete all documents required to be
filed with the Federal Trade Commission and the Department of Justice in order
to comply with the HSR Act and, together with the Persons who are required to
join in such filings, will file the same with the appropriate Governmental
Entities. The parties hereto promptly will furnish all materials thereafter
required by any of the Governmental Entities having jurisdiction over such
filings and will take all reasonable actions and file and use all reasonable
efforts to have declared effective or approved all documents and notifications
with any such Governmental Entities, as may be required under the HSR Act for
the consummation of the Mergers.

    (b) The parties hereto will use their best efforts to resolve such
objections, if any, as may be asserted with respect to the transactions
contemplated by this Agreement under any antitrust, competition or trade
regulatory laws, rules or regulations of any domestic or foreign Governmental
Entity ("ANTITRUST LAWS"). If any suit is threatened or instituted challenging
the Mergers as violating any Antitrust Law, the parties hereto will take such
action as may be required (i) by the applicable Governmental Entity in order to
resolve such objections as such Governmental Entity may have to such
transactions under such Antitrust Law or (ii) by any domestic or foreign court
or similar tribunal, in any suit brought by a private party or governmental
authority challenging the Mergers as violating any Antitrust Law, in order to
avoid the entry of, or to effect the dissolution of, any injunction, temporary
restraining order or other order that has the effect of preventing the
consummation of the Mergers. The entry by a court, in any suit brought by a
private party or Governmental Entity challenging the Mergers as violating any
Antitrust Law, of an order or decree permitting the Mergers but requiring that
any of the businesses or assets of any party hereto be divested or held separate
by Newco, or that would otherwise limit Newco's freedom of action with respect
to, or its ability to retain, both MindSpring and EarthLink or any portion
thereof, will not be deemed a failure to satisfy the conditions specified in
SECTION 10.1(E).

    (c) Each party promptly will inform the others of any material communication
from the Federal Trade Commission, the Department of Justice, the FCC or any
other domestic or foreign Governmental Entity regarding any of the transactions
contemplated by this Agreement. If any party or any Affiliate thereof receives a
request for additional information or documentary material from any such
government or authority with respect to the transactions contemplated by this
Agreement, such party will endeavor in good faith to make, as soon as reasonably
practicable and after consultation with the other parties, an appropriate
response to such request. Each party hereto promptly will advise the other
parties hereto in respect of any understandings, undertakings or agreements
which the advising party proposes to make or enter into with the Federal Trade
Commission, the Department of Justice or any other domestic or foreign
Governmental Entity in connection with the transactions contemplated by this
Agreement.

                             AMENDMENT NUMBER 2 TO
                      AGREEMENT AND PLAN OF REORGANIZATION

    This Amendment Number 2 to Agreement and Plan of Reorganization (the
"Amendment") is entered as of January 4, 2000 ("Effective Date"), among
EarthLink Network, Inc., MindSpring Enterprises, Inc. and WWW Holdings, Inc.
Capitalized terms used herein and not otherwise defined herein shall have the
meaning ascribed to such terms in the Agreement.

    The parties hereto are also parties to that certain Agreement and Plan of
Reorganization dated September 22, 1999, as amended (the "Agreement"). The
parties believe that it is in the interest of each of the parties and beneficial
to the shareholders of each of the parties for EarthLink to enter into a
Strategic Alliance with Apple Computer, Inc. and Apple Computer, Inc. Limited
(collectively "Apple") as described in all material respects in Exhibits A
through E hereto (the "Apple Transaction").

    NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereby agree as follows:

    1. MindSpring hereby consents to, and approves, in each and every aspect the
Apple Transaction, as described in Exhibits A through E hereto, and all actions
that are necessary by EarthLink to consummate such transaction.

    2. Each of EarthLink and MindSpring hereby waives any representation,
warranties and covenants in the Agreement to the extent (but only to the extent)
necessary to allow EarthLink to negotiate the Apple Transaction and to enter
into a definitive agreement with respect to, and to consummate, the Apple
Transaction. Each of EarthLink and MindSpring waives the conditions precedent
set forth in Sections 10.2(a) and 10.3(a) of the Agreement, respectively, to the
extent (but only to the extent) that such conditions would not be satisfied as a
result of EarthLink negotiating and entering into a definitive agreement with
respect to, and consummating, the Apple Transaction.

    3. Section 2.1(f) of the Agreement is amended by adding the following
sentence to the end thereof: "Each share of EarthLink Series C Preferred shall
be converted into 1.615 shares of newly created Newco Series C Preferred, having
terms, conditions, rights, preferences and designations substantially similar to
the EarthLink Series C Preferred."

    4. The following additional definitions are added to Section 1.1(a) of the
Agreement: "EarthLink Series C Preferred" shall mean the Series C Convertible
Preferred Stock of EarthLink, par value $0.01 per share; and "Newco Series C
Preferred" shall mean the Series C Convertible Preferred Stock of Newco, par
value $0.01, per share.

    5. The definitions of "EarthLink Preferred Stock" and "Newco Preferred
Stock" set forth in Section 1.1(a) of the Agreement are amended to include the
"EarthLink Series C Preferred" and "Newco Series C Preferred" referred to above,
respectively, and the definition of "Acquisition Proposal for EarthLink" set
forth in Section 1.1(a) of the Agreement is amended by adding "or the Apple
Transaction" to the end of the sentence.

    6. EarthLink, MindSpring and Newco each agree that the Apple Transaction,
including all rights, obligations and conditions (including all rights,
obligations and conditions pursuant to the agreements set forth in Exhibits A
through E hereto, and any other agreement executed in connection therewith) is,
and will be, binding on and inure to the benefit of Newco upon the Mergers, and
will be enforceable against Newco by Apple in accordance with their respective
terms.

    7. Notwithstanding any reduction in the size of the Board of Directors of
Newco, EarthLink, MindSpring and Newco shall cause the Nominating Committee (as
defined in Section 4.2 of the Agreement) to nominate the person selected by the
holders of the EarthLink Series C Preferred as an Outside Director, according to
the rights granted such holders in the Apple Transaction. EarthLink, MindSpring
and Newco shall also cause such person to be elected to the Board of Directors
of Newco. Notwithstanding the above, the person selected by the holders of the
EarthLink Series C Preferred as
<PAGE>
an Outside Director will be selected as the second Outside Director by the
Nominating Committee. The person selected by the holders of the EarthLink
Series C Preferred as an Outside Director shall be indemnified and covered by
directors' and officers' liability insurance to the same extent as each other
nonemployee director of Newco is so indemnified and insured.

    8. EarthLink, MindSpring and Newco shall cause the Certificate of Merger,
Restated Certificate of Incorporation of Newco and Bylaws of Newco to be revised
to reflect the rights, obligations and conditions of the Apple Transaction
(including all rights, obligations and conditions pursuant to the agreements set
forth in Exhibits A through E hereto, and any other agreement executed in
connection therewith).

    9. Section 5.5(a) of the Agreement is amended by replacing the first
sentence of Section 5.5(a) with the following: "The authorized capital stock of
EarthLink consists of 200,000,000 shares of EarthLink Common Stock, 10,000,000
shares of EarthLink Series A Preferred, 625,000 shares of EarthLink Series B
Preferred, and 4,385,965 shares of EarthLink Series C Preferred."

    10. Except as specifically amended and modified by the Amendment, the
Agreement shall remain in full force and effect and is hereby ratified and
affirmed by EarthLink, MindSpring and Newco.

    IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be duly
executed by their respective authorized officers as of the Effective Date.

Board of Directors
EarthLink Network, Inc.
3100 New York Drive
Pasadena, California 91107

Dear Sirs:

    You have asked us to advise you with respect to the fairness from a
financial point of view of the Common Stock Exchange Ratio to the Common
Stockholders, the Series A Exchange Ratio to the Series A Stockholders and the
Series B Exchange Ratio to the Series B Stockholders (as such terms are defined
below) as provided by the Agreement and Plan of Reorganization (the
"Reorganization Agreement"), dated as of September 22, 1999, among EarthLink
Network, Inc. ("EarthLink"), MindSpring Enterprises, Inc. ("MindSpring"), and
WWW Holdings, Inc., a newly formed corporation owned equally by EarthLink and
MindSpring ("Newco"). The Reorganization Agreement provides for, among other
things, (i) the merger (the "Merger") of EarthLink with and into Newco with
(A) each outstanding share of common stock, par value $0.01 per share (the
"EarthLink Common Stock"), of EarthLink being converted into 1.615 (the "Common
Stock Exchange Ratio") shares of common stock, par value $0.01 per share ("Newco
Common Stock"), of Newco, (B) each share of Series A convertible preferred
stock, par value $0.01 per share (the "Series A Preferred Stock"), of EarthLink
being converted into 1.615 (the "Series A Exchange Ratio") shares of Series A
convertible preferred stock, par value $0.01 per share (the "Newco Series A
Preferred Stock"), of Newco, and (C) each share of Series B convertible
preferred stock, par value $0.01 per share (the "Series B Preferred Stock"), of
EarthLink being converted into 1.615 (the "Series B Exchange Ratio") shares of
Series B convertible preferred stock, par value $0.01 per share (the "Newco
Series B Preferred Stock"), of Newco and (ii) the merger (the "MindSpring
Merger", and together with the Merger, the "Transaction") of MindSpring with and
into Newco with each outstanding share of common stock, par value $0.01 per
share, of MindSpring being converted into one (1) share of Newco Common Stock.
For purposes of this opinion, "Common Stock Stockholders" shall mean the holders
of the EarthLink Common Stock, other than MindSpring and its affiliates,
"Series A Stockholders" shall mean the holders of the Series A Preferred Stock,
and "Series B Stockholders" shall mean the holders of the Series B Preferred
Stock.

    In arriving at our opinion, we have reviewed certain publicly available
business and financial information relating to EarthLink and MindSpring, as well
as the Reorganization Agreement. We have reviewed certain other information,
including financial forecasts, provided to us by EarthLink and MindSpring, and
have met with the managements of EarthLink and MindSpring to discuss the
business and prospects of EarthLink and MindSpring, respectively. We have also
relied upon the views of EarthLink's and MindSpring's management concerning the
business, operational and strategic benefits and implications of the
Transaction, including financial information provided to us by EarthLink and
MindSpring relating to the synergistic values and operating cost savings
expected to be achieved through the combination of the operations of EarthLink
and MindSpring. We have also considered certain financial and stock market data
of EarthLink and MindSpring, and we have compared that data with similar data
for other publicly held companies in businesses we deemed to be similar to those
of EarthLink and MindSpring and we have considered the financial terms, to the
extent publicly available, of certain other business combinations and other
transactions which have recently been effected. We
<PAGE>

Page 2

also considered such other information, financial studies, analyses and
investigations and financial, economic and market criteria which we deemed
relevant.

    In connection with our review, we have not assumed any responsibility for
independent verification of any of the foregoing information and have relied on
it being complete and accurate in all material respects. We have assumed that
any estimates or information used in our analysis have been reasonably prepared
on bases reflecting the best currently available estimates and judgments of the
managements of EarthLink and MindSpring as to the future financial performance
of EarthLink and MindSpring, respectively, and, upon consummation of the
Transaction, Newco. In addition, we have not made an independent evaluation or
appraisal of the assets or liabilities (contingent or otherwise) of EarthLink or
MindSpring, nor have we been furnished with any such evaluations or appraisals.
Our opinion is necessarily based upon financial, economic, market and other
conditions as they exist and can be evaluated on the date hereof.

    We are not expressing any opinion as to the value of the Newco Common Stock,
Newco Series A Preferred Stock or Newco Series B Preferred Stock when issued to
EarthLink's stockholders pursuant to the Merger or the prices at which Newco
Common Stock, Newco Series A Preferred Stock or Newco Series B Preferred Stock
will trade subsequent to the Transaction. With your consent, we have not
considered, and this opinion does not in any manner address, the impact of the
Transaction on any governance rights or other rights or interests that holders
of Series A Preferred Stock or Series B Preferred Stock may have with respect to
EarthLink under the terms of such securities or pursuant to agreements with
EarthLink and / or any third parties.

    We have acted as financial advisor to EarthLink in connection with the
Merger and will receive a fee for our services, a significant portion of which
is contingent upon the consummation of the Merger. In the past, we have
performed certain investment banking services for EarthLink and have received
customary fees for such services.

    In the ordinary course of our business, we and our affiliates may actively
trade the debt and equity securities of both EarthLink and MindSpring for our
and such affiliates' own accounts and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.

    It is understood that this letter is for the information of Board of
Directors of EarthLink in connection with its consideration of the Merger, does
not constitute a recommendation to any stockholder as to how such stockholder
should vote on the proposed Merger and is not to be quoted or referred to, in
whole or in part, in any registration statement, prospectus or proxy statement,
or in any other document used in connection with the offering or sale of
securities, nor shall this letter be used for any other purposes, without our
prior written consent.

    Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Common Stock Exchange Ratio is fair from a financial point of
view to the Common Stockholders, the Series A Exchange Ratio is fair from a
financial point of view to the Series A Stockholders and the Series B Exchange
Ratio is fair from a financial point of view to the Series B Stockholders.

Very truly yours,
CREDIT SUISSE FIRST BOSTON CORPORATION

Board of Directors
MindSpring Enterprises, Inc.
1430 West Peachtree St. NW
Suite 400
Atlanta, GA 30309

Dear Sirs:

    You have requested our opinion as to the fairness from a financial point of
view to the stockholders of MindSpring Enterprises, Inc. (the "Company") of the
Exchange Ratio (as defined below) pursuant to the terms of the Agreement and
Plan of Reorganization, dated as of September 22, 1999 (the "Agreement"), by and
among WWW Holdings, Inc., a Delaware corporation ("Newco"), EarthLink
Network, Inc., a Delaware corporation ("EarthLink") and the Company pursuant to
which EarthLink and the Company will be merged (the "Merger") with and into
Newco.

    Pursuant to the Agreement, each share of common stock of the Company will be
converted into 1.0 share of Newco common stock (the "Exchange Ratio") and each
share of common stock of EarthLink will be converted into 1.615 shares of Newco
common stock.

    In arriving at our opinion, we have reviewed (i) the draft dated
September 21, 1999 of the Agreement and the exhibits thereto; (ii) financial and
other information that was publicly available or furnished to us by the Company
and EarthLink including information provided during discussions with their
respective managements; (iii) certain financial projections of the Company,
EarthLink and on a pro forma basis, for the combined company provided during
discussions with the respective managements; (iv) certain financial and
securities data of the Company and EarthLink compared with various other
companies whose securities are traded in public markets; and (v) the historical
stock prices of the common stock of the Company and EarthLink. In addition, we
have conducted such other financial studies, analyses and investigations as we
deemed appropriate for purposes of this opinion.

    In rendering our opinion, we have relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
us from public sources, that was provided to us by the Company and EarthLink or
their representatives, or that was otherwise reviewed by us. In particular, we
have relied upon the estimates of the management of the Company of the operating
synergies achievable as a result of the Merger and upon our discussion of such
synergies with the management of EarthLink. With respect to the financial
projections supplied to us, we have relied on representations that they have
been reasonably prepared on the basis reflecting the best currently available
estimates and judgments of the management of the Company and EarthLink as to the
future operating and financial performance of the Company, EarthLink and the pro
forma combined company. We have not assumed any responsibility for making an
independent evaluation of any assets or liabilities or for making any
independent verification of any of the information reviewed by us. We have
relied as to certain legal matters on advice of counsel to the Company.

    Our opinion is necessarily based on economic, market, financial and other
conditions as they exist on, and on the information made available to us as of
the date of this letter. It should be understood

that, although subsequent developments may affect this opinion, we do not have
any obligation to update, revise or reaffirm this opinion. We are expressing no
opinion herein as to the prices at which Newco common stock will actually trade
at any time. Our opinion does not address the terms and conditions of the
Agreement and the exhibits thereto, other than the Exchange Ratio. In addition,
our opinion does not address the relative merits of the Merger and the other
business strategies considered by the Company's Board of Directors, nor does it
address the Board's decision to proceed with the Merger. Our opinion does not
constitute a recommendation to any stockholder as to how such stockholder should
vote on the proposed transaction.

    Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ"), as part of its
investment banking services, is regularly engaged in the valuation of businesses
and securities in connection with mergers, acquisitions, underwritings, sales
and distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. DLJ has performed investment
banking and other services for the Company in the past and has received
customary compensation for such services. Such services consisted of acting as
lead manager of the Company's May 29, 1998 equity offering, a co-manager of the
Company's December 14, 1998 equity offering and a co-manager of the Company's
April 7, 1999 concurrent equity and convertible debt offerings.

    Based upon the foregoing and such other factors as we deem relevant, we are
of the opinion that the Exchange Ratio is fair to the stockholders of the
Company from a financial point of view.

                                          Very truly yours,
