Dear Stockholders:
 
    On behalf of the entire Board of Directors of EarthLink Network, Inc. (the
"Company"), I am pleased to present this Proxy Statement/Prospectus, which
relates to a Special Meeting of Stockholders at which the Company will seek the
stockholder approvals necessary to consummate its pending transaction with
Sprint Corporation.
 
    This transaction, which was first announced on February 10, 1998, represents
a long-term strategic alliance creating what we believe will be one of the
industry's most powerful Internet access services. The Special Meeting will be
held in the Company's Executive Conference Room at 9:00 a.m. on June 5, 1998.
You are very cordially invited to attend.
 
    The Board of Directors unanimously approved the transaction and recommends
that you vote FOR approval of each of the enclosed proposals, ALL of which must
be adopted for the transaction to be closed and implemented. The Board's reasons
for unanimously approving the transaction are described in more detail below
under the section entitled "Recommendation of the Board of Directors." I
encourage you to read the enclosed materials carefully and call us if you have
any questions. We enthusiastically support the transaction and would be happy to
help facilitate your understanding of it as well.
 
    Again, on behalf of the entire Board, I urge you to vote FOR approval of
each of the stockholder proposals. We appreciate your support and look forward
to continuing to serve you.
 
                                          Sincerely,
 
                                          /s/ Sky D. Dayton

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
                    TO BE HELD AT 9:00 A.M. ON JUNE 5, 1998
 
To the Stockholders of EarthLink Network, Inc.:
 
    NOTICE IS HEREBY GIVEN that a special meeting of the stockholders (the
"Special Meeting") of EarthLink Network, Inc. (the "Company") will be held at
the Executive Conference Room of the Company, on Friday June 5, 1998, at 9:00
a.m., local time, to consider and vote upon the following four proposals (the
"Company Stockholder Vote Matters") contemplated by the Investment Agreement,
dated as of February 10, 1998, among the Company, Sprint Corporation ("Sprint"),
Sprint Communications Company L.P. ("Sprint L.P."), Dolphin, Inc. ("Newco") and
Dolphin Sub, Inc. ("Newco Sub, Inc.") as such agreement may be amended (the
"Investment Agreement," a copy of which is attached as Appendix A to the
accompanying Proxy Statement/Prospectus and is incorporated by reference
herein):
 
    1.  To approve and adopt an Agreement and Plan of Merger, dated as of
February 10, 1998, by and among the Company, Newco and Newco Sub, as such
agreement may be amended (the "Merger Agreement," a copy of which is attached to
the accompanying Proxy Statement/Prospectus as Appendix B and incorporated by
reference herein), pursuant to which (a) Newco Sub will merge with and into the
Company, with the Company as the surviving corporation (the "Merger"), and (b)
each outstanding share of common stock, par value $.01 per share of the Company
("Company Common Stock") outstanding at the effective time of the Merger will be
converted into the right to receive one share of common stock, par value $.01
per share of Newco ("Newco Common Stock") ("Proposal No. 1").
 
    2.  To approve the issuance by Newco of 4,102,941 shares of Series A
Convertible Preferred Stock (the "Convertible Preferred Stock"), the terms of
which are set forth in the proposed form of Certificate of Designation,
Preferences and Rights of Series A Preferred Stock (the "Certificate of
Designation") attached to the accompanying Proxy Statement/Prospectus as
Appendix C and incorporated herein by reference to Sprint L.P. and the issuance
of Newco Common Stock upon conversion thereof pursuant to the Investment
Agreement ("Proposal No. 2").
 
    3.  To approve the issuance by Newco of Convertible Senior Promissory Notes
(the "Convertible Notes") to Sprint and the issuance of Newco Common Stock upon
conversion thereof pursuant to the Credit Agreement, dated as of February 10,
1998, among the Company, Newco and Sprint, as such agreement may be amended (the
"Credit Agreement," a copy of which is attached as Appendix D to the
accompanying Proxy Statement/Prospectus and incorporated by reference herein),
("Proposal No. 3").
 
    4.  To approve and adopt amendments to the agreements governing outstanding
options, warrants and other rights to acquire Company Common Stock which
thereafter will only permit the issuance of Newco Common Stock rather than
Company Common Stock upon exercise thereof ("Proposal No. 4").
 
    THE APPROVAL OF EACH OF THE COMPANY STOCKHOLDER VOTE MATTERS IS CONTINGENT
ON THE APPROVAL OF ALL FOUR OF THE COMPANY STOCKHOLDER VOTE MATTERS. UNLESS ALL
FOUR OF THE COMPANY STOCKHOLDER VOTE MATTERS ARE APPROVED BY COMPANY
STOCKHOLDERS AT THE SPECIAL MEETING, NONE WILL BE EFFECTED BY THE COMPANY.
 
    The close of business on May 1, 1998, has been designated as the record date
(the "Record Date") for the determination of stockholders of the Company
entitled to notice of and to vote at the Special Meeting, or any adjournment or
postponement thereof on, the Company Stockholder Vote Matters. A complete list
of stockholders entitled to vote at the Special Meeting will be maintained at
the Company's headquarters at 3100 New York Drive, Pasadena, California, for a
period of 10 days prior to the Special Meeting.
<PAGE>
    Approval of Proposal No. 1 requires the affirmative vote of a majority of
the Company's Common Stock outstanding on the Record Date. Approval of the other
Company Stockholder Vote Matters requires the affirmative vote of the Shares
present in person or represented by proxy at the Special Meeting and entitled to
vote thereon. The shares of Newco Common Stock to be issued in connection with
the Merger will be qualified for trading on the Nasdaq National Market.
Consequently, holders of Company Common Stock will not have appraisal rights
with respect to the Merger under the Delaware General Corporation Law, but may
have dissenters' rights under the California General Corporation Law (the
"CGCL") because EarthLink may be considered a "quasi-California corporation"
under Section 2115 of the CGCL. See Appendix G, "Dissenters' Rights Under the
California General Corporation Law."
 
    THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT STOCKHOLDERS VOTE FOR
APPROVAL OF EACH OF THE COMPANY STOCKHOLDER VOTE MATTERS.
 
                                          BY ORDER OF THE BOARD OF DIRECTORS
 
                                          /s/ Sky D. Dayton
 
                                          SKY D. DAYTON

    FOLLOWING IS A SUMMARY OF CERTAIN INFORMATION CONTAINED IN THIS PROXY
STATEMENT/PROSPECTUS AND THE DOCUMENTS ATTACHED AS APPENDICES HERETO. THIS
SUMMARY IS NOT INTENDED TO BE A COMPLETE DESCRIPTION OF THE MATTERS COVERED IN
THIS PROXY STATEMENT/PROSPECTUS AND IS QUALIFIED IN ITS ENTIRETY BY THE MORE
DETAILED INFORMATION APPEARING ELSEWHERE OR INCORPORATED BY REFERENCE IN THIS
PROXY STATEMENT/PROSPECTUS. STOCKHOLDERS ARE URGED TO READ CAREFULLY THE ENTIRE
PROXY STATEMENT/PROSPECTUS, INCLUDING THE APPENDICES.
 
OVERVIEW
 
    On February 10, 1998, the Company established a broad strategic relationship
with Sprint and its affiliate, Sprint L.P. (the "Strategic Alliance") pursuant
to an Investment Agreement (as defined herein) and several other related
agreements and documents. As a result, certain elements of this Strategic
Alliance require approval by the Company's stockholders at the Special Meeting.
Consequently, this Proxy Statement/Prospectus constitutes a Proxy Statement by
which the Board of Directors of the Company is soliciting the proxy of the
Company's stockholders (i.e., the right to vote their shares of Company stock on
their behalf) at the upcoming Special Meeting of the Company's stockholders. At
the Special Meeting, the Company's stockholders will be asked to consider and
vote on several proposals which are elements of the Strategic Alliance,
including: (a) the Merger and a resulting conversion of each share of Company
Common Stock into one share of Newco Common Stock, (b) the issuance by Newco of
Series A Convertible Preferred Stock, $.01 par value per share (the "Convertible
Preferred Stock") to Sprint L.P. and the issuance of Newco Common Stock upon
conversion thereof, (c) the issuance of Convertible Notes (as defined herein) to
Sprint and the issuance of Newco Common Stock upon conversion thereof, and (d)
amendments to agreements governing options, warrants and rights to acquire
Company Common Stock which thereafter permit only the issuance of Newco Common
Stock upon exercise thereof.
 
    This Proxy Statement/Prospectus also constitutes the Prospectus to be
utilized by Newco for the issuance of Newco Common Stock to stockholders of the
Company in connection with the Merger and the Newco Common Stock into which
certain outstanding options, warrants and other rights to acquire Newco Common
Stock are excercisable.
 
THE PARTIES
 
    THE COMPANY.  The Company is a Delaware corporation with its principal
executive offices at 3100 New York Drive, Pasadena, California 91107, and its
telephone number is (626) 296-2400. The Company's principal line of business is
to serve as an Internet service provider that provides its customers access to
the Internet and information, assistance and services designed to introduce
customers to the Internet and ensure that they have a satisfying Internet
experience. See "Available Information" and "The Business of EarthLink."
 
    NEWCO AND NEWCO SUB.  Newco and Newco Sub are nominally capitalized Delaware
corporations created as vehicles for effectuating the transactions contemplated
by the Investment Agreement (as defined herein). The principal executive offices
and phone number of each of Newco and Newco Sub are that of the Company. Neither
Newco nor Newco Sub has conducted any business prior to the date of this Proxy
Statement, and neither Newco nor Newco Sub will conduct any business prior to
consummation of the Merger. Prior to consummation of the Merger, Newco and Newco
Sub are controlled by the Company, and Sprint has no interest in either company.
 
    Following the consummation of the Merger, Newco will become a public company
subject to the reporting requirements of the Exchange Act, and the Company will
be its subsidiary. It is expected that the Shares, after they are converted into
shares of Newco Common Stock, will continue to trade under the ticker symbol
"ELNK" on the Nasdaq National Market. Upon consummation of the Merger, Sprint
and its affiliates will own approximately 26.6% of the total number of issued
and outstanding shares of Newco
 
<PAGE>
Common Stock on a fully-diluted basis (that is, assuming that all warrants,
options and convertible notes representing rights to purchase Common Stock or
Newco Common Stock, including the Convertible Preferred Stock of Newco issued to
Sprint L.P., are exercised or converted into Newco Common Stock). See
"Summary--The Issuance of Convertible Preferred Stock," "Description of the
Offer" and "Description of the Investment Agreement--The Investment Agreement."
 
    SPRINT AND SPRINT L.P.  Sprint is a Kansas corporation with its principal
executive offices at 2330 Shawnee Mission Parkway, Westwood, Kansas 66205.
Sprint is a diversified telecommunications holding company providing domestic
and international voice, video and data communications through its subsidiaries.
Sprint has two major business divisions: local telephone operations and
long-distance operations. Complimentary businesses include distribution of
telecommunications equipment and telephone directory publishing. Sprint
affiliates operate local exchange telephone systems serving more than seven
million access lines in 19 states. Sprint L.P. operates the long-distance
communications services division of Sprint and is a Delaware limited partnership
owned by affiliates of Sprint. See "Available Information" and "Information
About Sprint."
 
SPECIAL MEETING OF STOCKHOLDERS
 
    This Proxy Statement/Prospectus is being furnished to the holders of Common
Stock in connection with the solicitation by the Company's Board of Directors of
proxies for use at the Special Meeting at which the stockholders of the Company
will be asked to vote upon (i) the Merger Agreement and the Merger, including
issuance of Newco Common Stock in exchange for Company Common Stock, (ii) the
issuance of Convertible Preferred Stock, the Newco Common Stock issuable upon
conversion thereof, (iii) the issuance of Convertible Notes and the Newco Common
Stock issuable upon conversion thereof, and (iv) amendments to option warrants
and other rights to acquire Company Common Stock to permit exercise of such
rights only into Newco Common Stock (the matters referred to in (i), (ii), (iii)
and (iv) are referred to collectively herein as the "Company Stockholder Vote
Matters"). The Special Meeting will be held at the Executive Conference Room of
the Company at 9:00 a.m. local time, on June 5, 1998. See "Special Meeting of
Stockholders--Date, Place, and Time" and "Company Stockholder Vote Matters."
 
    The Company's Board of Directors has fixed the close of business on May 1,
1998, as the record date (the "Record Date") for the determination of
stockholders entitled to notice of and to vote at the Special Meeting. Only
holders of record of shares of Common Stock on the Record Date are entitled to
notice of and to vote at the Special Meeting. Each share of Common Stock is
entitled to one vote. Stockholders who execute proxies retain the right to
revoke them at any time prior to being voted at the Special Meeting. On the
Record Date, there were 12,059,784 shares of Common Stock issued and
outstanding. See "Special Meeting of Stockholders--Record Date, Voting Rights,
Required Votes and Revocability of Proxies."
 
    Approval of the Merger requires the affirmative vote of a majority of the
Shares outstanding as of the Record Date. Approval of each of the other Company
Stockholder Vote Matters requires the affirmative vote of a majority of the
Shares represented in person or by proxy at the Special Meeting, entitled to
vote thereon, assuming a quorum is present. See "Special Meeting of
Stockholders--Record Date, Voting Rights, Required Votes and Revocability of
Proxies."
 
    THE APPROVAL OF EACH OF THE COMPANY STOCKHOLDER VOTE MATTERS IS CONTINGENT
ON THE APPROVAL OF ALL OF THE COMPANY STOCKHOLDER VOTE MATTERS. UNLESS ALL FOUR
OF THE COMPANY STOCKHOLDER MATTERS ARE APPROVED BY COMPANY STOCKHOLDERS AT THE
SPECIAL MEETING, NONE WILL BE EFFECTED BY THE COMPANY.
 
                                       2
<PAGE>
    As of the Record Date, officers and directors of the Company owned 4,643,427
Shares, representing 38.5% of the Common Stock outstanding. In order to induce
Sprint and Sprint L.P. to enter into the Investment Agreement and perform the
transactions contemplated thereby, certain members of management and other
stockholders (the "Granting Stockholders") have entered into an Agreement to
Vote and Tender Stock dated February 10, 1998 ("Agreement to Vote and Tender
Stock"). That agreement obligates the Granting Stockholders to tender all of the
3,989,114 Shares (representing 35.3% of the outstanding Shares) which they own
into the tender offer by Sprint described below, and to vote those Shares in
favor of each of the Company Stockholder Vote Matters. In order to ensure that
the agreement to vote set forth in the Agreement to Vote and Tender Stock will
be fulfilled, each of the Granting Stockholders granted to Sprint an Irrevocable
Proxy, coupled with an interest, to vote in favor of the Company Stockholder
Vote Matters (the "Irrevocable Proxies"). The Granting Stockholders are Sky
Dayton, Chairman of the Board of the Company, 1,500,000 Shares; Kevin M.
O'Donnell, a Director of the Company, 944,614 Shares; Storie Partners, L.P.,
521,892 Shares; Gregory Abbott, 427,212 Shares; Robert S. London, 392,032
Shares; and George Abbott, 203,364 Shares.
 
    In addition, certain other stockholders (the "Voting Stockholders") have
entered into an Agreement to Vote Stock dated February 10, 1998 ("Agreement to
Vote Stock") which obligates them to vote all of their 2,950,382 Shares
(representing 26.1% of the outstanding Shares) in favor of the Company
Stockholder Vote Matters, but did not grant any irrevocable proxies thereunder.
The Voting Stockholders are Quantum Industrial Partners LDC, 1,456,480 Shares;
Reed Slatkin, a Director of the Company (through Reed Slatkin & Associates),
1,042,473 Shares; Sidney Azeez, a Director of the Company, 236,884 Shares; and
George Soros, 214,545 Shares.
 
    Based on the foregoing, the Company believes that at least 6,939,496 Shares
(representing 61.4% of the outstanding Shares as of February 10, 1998) will be
voted in favor of the Company Stockholder Vote Matters. The number of Shares
obligated to be tendered and/or voted pursuant to these agreements will ensure
approval of (i) the Company Stockholder Vote Matters, (ii) satisfaction of the
Minimum Tender Condition (as defined herein), and (iii) consummation of the
transactions contemplated by the Investment Agreement, unless the Investment
Agreement Conditions (as defined herein) have not been satisfied or waived on or
prior to the time the Offer is consummated. Sprint did not own of record any
Shares as of the Record Date, and therefore is not entitled to vote at the
Special Meeting except insofar as it exercises the Irrevocable Proxies provided
by the Granting Stockholders.
 
THE OFFER
 
    By means of an Offer to Purchase (the "Offer to Purchase") and a related
Letter of Transmittal (the "Letter of Transmittal"), each dated February 18,
1998, Sprint has offered to purchase 1,250,000 shares of Common Stock of the
Company at $45.00 per Share (the "Offer Price"), net to each seller in cash,
upon the terms and subject to the conditions set forth in the Offer to Purchase
and in the Letter of Transmittal (which, together with any amendments or
supplements thereto, collectively constitute the "Offer"). The Offer is made
pursuant to the Investment Agreement and certain related agreements described
herein. Upon consummation of the Offer, Sprint will own approximately 11.1% of
the total number of issued and outstanding shares (determined as of February 10,
1998), which will be converted into the same number of shares of Newco Common
Stock in the Merger.
 
    Consummation of the Offer is conditioned upon (i) there being validly
tendered and not withdrawn prior to the "Expiration Date" (as defined herein)
1,250,000 Shares (the "Minimum Tender Condition"), and (ii) the other conditions
to the obligations of Sprint, Sprint L.P., Newco, Newco Sub and the Company to
consummate the transactions contemplated by the Investment Agreement (other than
the acceptance for payment of Shares pursuant to the Offer) having been
satisfied or waived (collectively, the "Investment Agreement Conditions"),
including the expiration or termination of all waiting periods imposed upon
consummation of the Offer and the other transactions contemplated by the
Investment Agreement by the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended, and the regulations thereunder (the
 
                                       3
<PAGE>
"HSR Act"), and the absence of any action taken or instituted by the Department
of Justice, the Federal Trade Commission or by any other governmental entity to
delay or otherwise enjoin the transactions contemplated by the Investment
Agreement (the "HSR Condition"). The applicable waiting period under the HSR Act
has expired such that the HSR Condition may now be considered satisfied. See
"Description of the Offer."
 
THE INVESTMENT AGREEMENT
 
    The Investment Agreement provides, among other things, that subject to the
terms and conditions set forth therein, immediately following the consummation
of the Offer, (i) the Merger will be effected and the issued and outstanding
Shares will be converted into shares of Newco Common Stock; (ii) Sprint L.P.
will acquire 4,102,941 shares of Convertible Preferred Stock, in exchange for
(A) an aggregate cash consideration of $23,750,000, (B) the assignment to Newco
of one hundred percent of the Sprint Internet Passport(SM) Subscribers ("SIP
Subscribers"), of which there were approximately 130,000 as of the date of
execution of the Investment Agreement, and (C) Sprint L.P. having entered into a
network agreement whereby Newco and the Company will utilize Sprint L.P.'s
long-distance network under specified terms and conditions (the issuance of such
Convertible Preferred Stock, the "Convertible Preferred Stock Issuance," and the
consideration described in (A), (B) and (C), collectively, the "Convertible
Preferred Stock Consideration"); and (iii) Sprint will provide Newco and the
Company, as co-borrowers, with up to $25 million of convertible senior debt
financing on or after the Closing (as defined below), with such amount to
increase by $25 million on each of the first, second and third anniversaries of
the Closing Date (as defined below) for a total of up to $100 million of such
financing at the end of such period (the "Convertible Debt Financing"), such
indebtedness to be evidenced by one or more Convertible Senior Promissory
Note(s) (the "Convertible Notes") and to be subject to the terms and conditions
of a Credit Agreement dated as of February 10, 1998 among Sprint, Newco and the
Company, as such agreement may be amended (the "Credit Agreement"). The Closing
of the Merger, the Convertible Preferred Stock Issuance and the other
transactions described in the Investment Agreement which will occur concurrently
with the Merger is referred to as the "Closing" and the date on which the
Closing occurs is referred to as the "Closing Date." See "Description of the
Investment Agreement."
 
THE GOVERNANCE AGREEMENT
 
    In connection with the Investment Agreement, Sprint, Sprint L.P., Newco and
the Company entered into the Governance Agreement, dated February 10, 1998, as
such agreement may be amended (the "Governance Agreement"), which will take
effect upon the Closing. The Governance Agreement establishes certain terms and
conditions concerning the corporate governance of Newco, the acquisition and
disposition of equity securities of Newco ("Equity Securities") by Sprint,
Sprint L.P. and any of their respective affiliates (collectively, "Affiliated
Equity Holders"), the rights of Sprint to make offers to purchase all of the
outstanding securities of Newco not owned by Affiliated Equity Holders and the
rights of the Board of Directors of Newco to receive and entertain offers to
effect Business Combinations (as defined below), all as more particularly
described in the Governance Agreement.
 
CERTAIN ANCILLARY AGREEMENTS
 
    Simultaneously with the execution of the Investment Agreement, the following
agreements were executed and delivered by the parties thereto: (i) the Merger
Agreement, (ii) the Agreement to Vote and Tender Stock, (iii) the Agreement to
Vote Stock, (iv) the Credit Agreement, (v) the Governance Agreement, (vi) a
Marketing and Distribution Agreement dated as of February 10, 1998 among Sprint,
Sprint L.P., Newco and the Company, as such agreement may be amended, whereby
Sprint, Sprint L.P., Newco and the Company agree to provide certain cooperation
and support to each other in specified marketing matters and Sprint L.P. grants
Newco the right to utilize certain distribution channels of Sprint L.P. and a
license to use Sprint L.P.'s brand in the business of the Company and the
Company agrees to sell
 
                                       4
<PAGE>
certain products of Sprint L.P. (the "Marketing Agreement"), (vii) a Network
Services Agreement dated as of February 10, 1998, as such agreement may be
amended, between Sprint L.P., Newco and the Company, which grants Newco and the
Company the right to use a minimum and maximum number of ports on Sprint L.P.'s
long-distance network, along with pricing and other terms set forth therein (the
"Network Agreement"), (viii) a Registration Rights Agreement dated as of
February 10, 1998, as such agreement may be amended, between Sprint, Sprint L.P.
and Newco establishing the rights of Sprint and its affiliates with respect to
public offerings and sales of equity securities of Newco and to obtain
registration thereof under federal and state securities laws (the "Registration
Rights Agreement"), and (ix) a Stockholders Agreement dated as of February 10,
1998, as such agreement may be amended, between Sprint and certain stockholders
of the Company which provides for certain rights and obligations with respect to
such stockholders' voting and disposition of equity securities of Newco in
connection with an offer by Sprint to acquire the remaining equity securities of
Newco (the "Stockholders Agreement"). The agreements referred to in (i), (iv),
(v), (vi), (vii), (viii) and (ix) will not become effective until the Closing
and then only if the Offer is consummated and the Investment Agreement
Conditions are satisfied or waived on or prior to the Closing. The Agreement and
Plan of Merger, the Agreement to Vote and Tender Stock, the Agreement to Vote
Stock, the Credit Agreement, the Governance Agreement, the Marketing Agreement,
the Network Agreement, the Registration Rights Agreement and the Stockholders
Agreement are referred to as the "Ancillary Agreements." See "Description of
Certain Ancillary Agreements."
 
THE MERGER
 
    Immediately following the consummation of the Offer, the Company, Newco and
Newco Sub will effect the Merger whereby Newco Sub, a wholly-owned subsidiary of
Newco, will merge with and into the Company. All of the then issued and
outstanding Shares of Common Stock, including the Shares acquired by Sprint in
the Offer, will be converted into an equal number of shares of Newco Common
Stock in the Merger. Upon consummation of Merger, the Company will be a
subsidiary of Newco. Pursuant to the Merger, the Certificate of Incorporation
and Bylaws of Newco Sub will become the Certificate of Incorporation and Bylaws
of the surviving corporation and the Certificate of Incorporation and Bylaws of
Newco will take effect as the constituent documents of the corporation whose
stock is registered pursuant to the Exchange Act. The Certificate of
Incorporation and Bylaws of Newco are substantially similar to the Certificate
of Incorporation and Bylaws of the Company, except that the number of authorized
shares of Preferred Stock was increased from 10 million to 25 million, the scope
of indemnification of officers and directors was increased consistent with the
DGCL, and the provision providing for cumulative voting was deleted. Also, the
directors and officers of the Company will become the directors and officers of
Newco until their successors have been duly elected or appointed and qualified
or until their earlier death, resignation or removal in accordance with Newco's
Certificate of Incorporation and Bylaws, except that the two directors elected
by the holders of the Convertible Preferred Stock will be elected immediately
following the Closing. Sprint's initial designees to such directorships are
William T. Esrey, the Chairman and Chief Executive Officer of Sprint and Patti
S. Manuel, President and Chief Operating Officer--Long-Distance Division of
Sprint. See "Company Stockholder Vote Matters-Approval of the Merger."
 
    While the Merger is subject to the approval of the stockholders of the
Company, the votes to be cast pursuant to the Agreement to Vote and Tender Stock
and the Agreement to Vote Stock will ensure approval of the Merger. The Merger
will create a holding company structure which may provide certain advantages if
the scope of the Company's business expands in the future as well as
facilitating the economic efficiency of the strategic relationship with Sprint.
See "Company Stockholder Vote Matters-Approval of the Merger."
 
THE ISSUANCE OF CONVERTIBLE PREFERRED STOCK
 
    Concurrently with the Merger, Sprint L.P. will receive 4,102,941 shares of
Convertible Preferred Stock in exchange for the Convertible Preferred Stock
Consideration. Such consideration consists of (i)
 
                                       5
<PAGE>
$23,750,000 of cash, (ii) Sprint L.P. contributing the SIP Subscribers to Newco,
and (iii) Sprint L.P., the Company and Newco entering into the Network
Agreement.
 
    The Convertible Preferred Stock will be initially convertible into 3,533,411
Shares of Newco Common Stock at the time of the Closing. Based on these figures,
immediately after consummation of the Offer, the Merger and the other
transactions contemplated by the Investment Agreement, Sprint would own
approximately 26.6% of the total number of issued and outstanding shares of
Newco Common Stock on a fully diluted basis (that is, assuming that all
warrants, options and convertible notes representing rights to purchase Common
Stock or Newco Common Stock, including the Convertible Preferred Stock, are
exercised or converted into Newco Common Stock). However, the Convertible
Preferred Stock will pay dividends thereon ("Liquidation Accretion Dividends")
for the first five years in the form of increases in its "Liquidation Value" (as
hereinafter defined), at a per annum rate of 3% of the Liquidation Value, which
will accrue and compound quarterly in arrears, but which will accelerate in the
event of a business combination or an optional redemption of the Convertible
Preferred Stock by Newco. At the Closing, the Liquidation Value will be the
average of the closing price per share of Newco Common Stock for the 30 trading
days prior to the Closing Date. Increases in the Liquidation Value will have the
effect of increasing the number of shares of Newco Common Stock that Sprint will
receive upon conversion of the Convertible Preferred Stock. Assuming that the
Convertible Preferred Stock is held by Sprint for the initial five year period
following the Closing or that certain "Liquidation Accretion Dividends" are
accelerated, Sprint L.P. will be entitled to receive 4,102,941 shares of Newco
Common Stock upon conversion thereof. If the fully diluted number of Shares, as
calculated above, were the same at that time, Sprint would then own
approximately 28.8% of the total number of issued and outstanding shares of
Newco Common Stock on that basis. Such percentage amount does not take into
account the extent to which, if any, Sprint's fully-diluted ownership interest
would increase in the event that advances are made under the Credit Agreement.
See "Description of Certain Ancillary Agreements--The Credit Agreement."
 
    Cash dividends at such rate are payable after five years from the Closing
Date when declared by the Board of Directors of Newco out of funds legally
available therefor and such dividends accumulate if not declared and paid. After
the twentieth anniversary of the Closing Date, such cumulative cash dividends
accrue at the rate per annum of 8% of the Liquidation Value, which rate
increases annually by 200 basis points up to a maximum rate of 12% per annum.
Holders of Convertible Preferred Stock are entitled to a liquidation preference
upon any voluntary or involuntary liquidation, dissolution or winding up of
Newco ("Liquidation Event") in an amount per share equal to the sum of (i) the
average closing price per share of Common Stock for the 30 trading days
preceding the Closing Date, (ii) the amount of all Liquidation Accretion
Dividends that have been paid (including an amount equal to a prorated dividend
for the period from the latest "Dividend Accrual Date" through the date of the
Liquidation Event), and (iii) all accumulations of accrued by unpaid cash
dividends (the sum of (i) (ii) and (iii) is referred to as the Liquidation
Value). Each share of Convertible Preferred Stock initially converts into less
than one share of Newco Common Stock but increases to a one-for-one conversion
(subject, in each case, to customary antidilution adjustments) over a five-year
period or upon acceleration in the event of a business combination or an
optional redemption by Newco. See "Company Stockholder Vote Matters--Proposal
No. 2-- Approval for the Issuance of Convertible Preferred Stock." The terms of
the Convertible Preferred Stock are set forth in the Certificate of Designation
attached hereto as Appendix C.
 
CONVERTIBLE DEBT FINANCING
 
    In connection with the Investment Agreement, the Company and Sprint entered
into the Credit Agreement, which will become effective concurrently with the
Merger. Under the Credit Agreement, Sprint will initially provide up to $25
million in debt financing to be evidenced by the Convertible Notes. Each year
after the Closing Date, the aggregate amount that Sprint is obligated to advance
will be increased by $25 million to a maximum of $100 million on a cumulative
basis. The Convertible Notes are convertible into shares of Newco Common Stock
at a conversion price of 130% of the average fair market
 
                                       6
<PAGE>
price (i.e., the closing sales price over a 30 trading day period) at the time a
particular Convertible Note is issued to evidence an advance under the Credit
Agreement. Each Convertible Note will mature five years from the date of
issuance and will bear interest at a rate equal to 6% per annum. The Company has
no present intention to incur indebtedness under the Credit Agreement.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS; FAIRNESS OPINION
 
    The Board of Directors of the Company has, by unanimous vote of all
Directors, approved the Offer, the Merger and the other transactions
contemplated by the Investment Agreement, and determined that the terms of all
such transactions, taken together, are fair to, and in the best interests of,
the stockholders of the Company. The Board has recommended that all stockholders
of the Company accept the Offer and tender their shares of Common Stock pursuant
to the Offer. The Board of Directors of the Company is also recommending that
all Company stockholders vote "FOR" approval and adoption of the Merger
Agreement and each of the other Company Stockholder Vote Matters. Although the
Board of Directors did not assign relative weights to the specific factors
considered in reaching its decision, the Board of Directors did consider the
overall strategic value of the relationship with Sprint to be of paramount
importance. The Company has retained Deutsche Morgan Grenfell Inc. ("DMG") as
its financial advisor for these matters. DMG has rendered an opinion to the
Board of Directors that, as of the date of such opinion, the Offer, the sale of
Convertible Preferred Stock and the Merger, when taken together, are fair from a
financial point of view to the holders of the Common Stock. See "Recommendation
of the Board of Directors" and the fairness opinion of DMG attached as Appendix
E hereto.
 
DISSENTERS' RIGHTS OF APPRAISAL
 
    Because the Common Stock was included on the Nasdaq National Market on the
Record Date and because the Common Stock will be converted in the Merger solely
into the right to receive Newco Common Stock, which will be included on the
Nasdaq National Market at the effective time of the Merger, pursuant to Section
262 of the DGCL, the holders of Common Stock will not have appraisal rights with
respect to the Merger under the DGCL. However, EarthLink, which was originally
incorporated as a California corporation (prior to being reincorporated as a
Delaware corporation in 1996), may be considered a "quasi-California
corporation" pursuant to Section 2115 of the CGCL. If so, the Company's
stockholders who have not approved the Merger may be entitled to dissenters'
rights under Chapter 13 of the CGCL in connection with the Merger if demands for
such rights are made with respect to (i) five percent or more of the outstanding
shares of Common Stock or (ii) "restricted shares" of Common Stock (i.e., those
shares with respect to which there exists any restriction or transfer imposed by
the Company or any law or regulation).
 
    The failure of dissenting stockholders to follow the appropriate procedures
to perfect his or her dissenters' rights under the CGCL will result in the
termination or waiver of such rights. In the event a stockholder fails to make a
proper demand for payment or otherwise loses his or her status as a dissenting
stockholder, such stockholder will be entitled to receive Newco Common Stock as
consideration under the Merger. See "Company Stockholder Vote Matters--Proposal
No. 1--Approval of the Merger--Dissenters' Rights of Appraisal."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
    It is intended that the Merger will be treated as a reorganization within
the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the
"Code"). If the Merger qualifies as a tax-free reorganization, (a) no gain or
loss will be recognized by a holder of Common Stock upon the exchange of such
Common Stock solely for shares of Newco Common Stock, (b) the basis of the Newco
Common Stock received by stockholders in the Merger will be the same as the
basis such stockholders had in their Company Common Stock, and (c) the holding
period of the Newco Common Stock received by stockholders in the Merger
generally will include the holding period such stockholders had in their Company
 
                                       7
<PAGE>
Common Stock. See "Company Stockholder Vote Matters--Proposal No. 1--Approval of
the Merger-- Certain Federal Income Tax Consequences."
 
EFFECTIVE TIME
 
    Subject to the conditions to the obligations of the parties to effect the
Merger being satisfied or waived, the Merger will become effective on the date
and at the time that the Certificate of Merger become effective with the
Delaware Secretary of State (the "Effective Time"). The Effective Time is
expected to occur as soon as practicable after approval of the Merger by the
Company's stockholders and the effective date (including expiration of all
applicable waiting periods) of all required consents of any regulatory authority
having jurisdiction over the Merger. See "Company Stockholder Vote Matters--
Proposal No. 1--Approval of the Merger--Effective Time of the Merger,"
"--Conditions" and "-- Termination."
 
    No assurance can be provided that the necessary stockholder and regulatory
approvals can be obtained or that the other conditions precedent to the Merger
can or will be satisfied. The Company anticipates that all conditions to the
consummation of the Merger will be satisfied so that the Merger can be
consummated during the second quarter of 1998. Delays in the consummation of the
Merger could occur, however.

                        SPECIAL MEETING OF STOCKHOLDERS
 
GENERAL; PURPOSE
 
    This Proxy Statement/Prospectus is being furnished to the holders of Common
Stock in connection with the solicitation by the Company's Board of Directors of
proxies for use at the Special Meeting at which Company stockholders will be
asked to vote upon proposals to approve the Company Stockholder Vote Matters.
Each of the Company Stockholder Vote Matters is described in detail in this
Proxy Statement/Prospectus, and include the following proposals:
 
    1. To approve and adopt an Agreement and Plan of Merger, dated as of
February 10, 1998, by and among the Company, Newco and Newco Sub, as such
agreement may be amended (the "Merger Agreement," a copy of which is attached
hereto as Appendix B to this Proxy Statement/Prospectus and incorporated by
reference herein), pursuant to which (a) Newco Sub will merge with and into the
Company, with the Company as the surviving corporation, and (b) each outstanding
share of Company Common Stock outstanding at the effective time of the Merger
will be converted into the right to receive one share of Newco Common Stock
("Proposal No. 1").
 
    2. To approve the issuance by Newco of 4,102,941 shares of Convertible
Preferred Stock to Sprint L.P. and the issuance of Newco Common Stock upon
conversion thereof pursuant to the Investment Agreement ("Proposal No. 2").
 
    3. To approve the issuance by Newco of Convertible Notes to Sprint and the
issuance of Newco Common Stock upon conversion thereof pursuant to the Credit
Agreement, a copy of which is attached as Appendix D to the accompanying Proxy
Statement/Prospectus and incorporated by reference herein), ("Proposal No. 3").
 
    4. To approve and adopt amendments to the agreements governing outstanding
options, warrants and other rights to acquire Company Common Stock which
thereafter will only permit the issuance of Newco Common Stock rather than
Company Common Stock upon exercise thereof ("Proposal No. 4").
 
    The transactions underlying the Company Stockholder Vote Matters arise in
connection with the Investment Agreement and all the transactions contemplated
therein between the Company, Newco, Newco Sub, Sprint and Sprint L.P., which is
described in detail below.
 
DATE, PLACE, TIME
 
    The Special Meeting will be held at the Executive Conference Room of the
Company at 9.00 a.m., local time, on Friday, June 5, 1998.
 
RECORD DATE, VOTING RIGHTS, REQUIRED VOTES, AND REVOCABILITY OF PROXIES
 
    The close of business on May 1, 1998, has been fixed as the Record Date for
determining holders of outstanding shares of Common Stock entitled to notice of
and to vote at the Special Meeting. Only holders of Common Stock of record on
the books of the Company at the close of business on the Record Date are
entitled to notice of and to vote at the Special Meeting. As of the Record Date,
12,059,784 shares of Common Stock were issued and outstanding and held by 176
holders of record.
 
    Holders of Common Stock are entitled to one vote on each matter considered
and voted upon at the Special Meeting for each share of Common Stock held of
record as of the Record Date. To hold a vote on any proposal, a quorum must be
assembled, which is a majority of the shares of Common Stock issued and
outstanding and entitled to vote, present in person or represented by proxy. In
determining whether a quorum exists at the Special Meeting for purposes of all
matters to be voted on, all votes "for" or "against," as well as all
abstentions, with respect to the proposal receiving the most such votes, will be
counted. The affirmative vote by the holders of a majority of the outstanding
shares of Common Stock on the Record Date is required to approve the Merger. The
vote required for the approval of the remaining
 
                                       10
<PAGE>
Company Stockholder Vote Matters is the affirmative vote by the holders of a
majority of the Shares present in person or represented by proxy at the Special
Meeting and entitled to vote thereon. Shares represented by proxies that reflect
abstentions or "broker non-votes" (i.e., shares held by a broker or nominee that
are represented at the Special Meeting, but with respect to which such broker or
nominee is not empowered to vote on a particular proposal) will be counted as
Shares that are present and entitled to vote for purposes of determining the
presence of a quorum. Accordingly, with respect to the approval of the Company
Stockholder Vote Matters, abstentions and broker non-votes will be counted as
part of the number of votes to be used in determining if the proposal has
received the requisite number of votes for approval. Thus, an abstention and a
broker non-vote will have the same effect as a vote against the proposal.
 
    Shares of Common Stock represented by properly executed proxies, if such
proxies are received in time and not revoked, will be voted in accordance with
the instructions indicated on the proxies.
 
    IF NO INSTRUCTIONS ARE INDICATED, SUCH PROXIES WILL BE VOTED FOR APPROVAL OF
THE COMPANY STOCKHOLDER VOTE MATTERS AND, IN THE DISCRETION OF THE PROXY HOLDER,
AS TO ANY OTHER MATTER WHICH MAY COME PROPERLY BEFORE THE SPECIAL MEETING. IF
NECESSARY, THE PROXY HOLDER MAY VOTE IN FAVOR OF A PROPOSAL TO ADJOURN THE
SPECIAL MEETING IN ORDER TO PERMIT FURTHER SOLICITATION OF PROXIES IN THE EVENT
THERE ARE NOT SUFFICIENT VOTES TO APPROVE THE FOREGOING PROPOSALS AT THE TIME OF
THE SPECIAL MEETING.
 
    FAILURE BOTH TO RETURN THE PROXY CARD AND TO VOTE IN PERSON AT THE SPECIAL
MEETING WILL HAVE THE EFFECT OF A VOTE CAST AGAINST APPROVAL OF THE MERGER.
 
    A stockholder, other than a Granting Stockholder, who has given a proxy may
revoke it at any time prior to its exercise at the Special Meeting by (i) giving
written notice of revocation to the Secretary of the Company, (ii) properly
submitting to the Company a duly executed proxy bearing a later date or (iii)
attending the Special Meeting and voting in person. All written notices of
revocation and other communications with respect to revocation of proxies should
be addressed as follows: EarthLink Network, Inc., 3100 New York Dr., Pasadena,
California 91107; Attention: Kirsten Hansen, Secretary.
 
    As of the Record Date, the directors and executive officers of the Company
and their affiliates were entitled to vote 4,643,427 shares of Common Stock,
excluding options and warrants, or approximately 38.5% of the issued and
outstanding shares of Common Stock. Sprint did not own of record any shares of
Common Stock as of the Record Date, and therefore is not entitled to vote at the
Special Meeting except insofar as it exercises the Irrevocable Proxies provided
by the Granting Stockholders.
 
    In connection with the Investment Agreement, certain members of management
and certain stockholders have entered into the Agreement to Vote and Tender
Stock and/or the Agreement to Vote, each of which obligates such parties, among
other things, to vote their respective shares in favor of the Company
Stockholder Vote Matters. The number of shares of Common Stock obligated to be
voted thereunder will ensure approval of the Company Stockholder Vote Matters.
See "Description of the Offer."
 
SOLICITATION OF PROXIES
 
    Proxies may be solicited by the directors, officers and employees of the
Company by mail, in person, or by telephone or telegraph. Such persons will
receive no additional compensation for such services. The Company may also
retain the services of a private firm to solicit proxies on behalf of the
Company, for which the Company would pay a fee. Any such brokers, custodians,
nominees, and fiduciaries forwarding solicitation materials to the beneficial
owners of Common Stock held of record by such persons will be reimbursed for the
reasonable out-of-pocket expenses incurred by them for such services. All
expenses
 
                                       11
<PAGE>
associated with the solicitation of proxies, other expenses associated with the
Special Meeting, and expenses related to the printing and mailing of this Proxy
Statement/Prospectus, will be paid by the Company, except that Sprint has agreed
in the Investment Agreement to pay one-half of the reasonable out-of-pocket
expenses incurred by the Company in preparing, printing and mailing the Proxy
Statement/ Prospectus, preparing the S-4 Registration Statement of which this
Proxy Statement is a part and holding the Special Meeting. See "Description of
the Investment Agreement--Expenses and Fees."

                            DESCRIPTION OF THE OFFER
 
    By means of the Offer to Purchase, the Letter of Transmittal and related
documentation sent to the stockholders of the Company on February 18, 1998,
Sprint has commenced a public tender offer to purchase 1,250,000 shares of
Common Stock of the Company at $45.00 per Share, net to each seller in cash,
upon the terms and subject to the conditions set forth in the Offer to Purchase
and in the Letter of Transmittal The Offer is made pursuant to the Investment
Agreement and certain related agreements described herein.
 
    Consummation of the Offer is conditioned upon (i) there being validly
tendered and not withdrawn prior to the Expiration Date 1,250,000 Shares, (ii)
the amendment of the Dilutable Securities (as defined herein) so that not more
than 8% of the Company Common Stock outstanding immediately prior to the Closing
will be subject to Dilutable Securities after the Merger (the "Amendment
Condition") and (iii) the other conditions to the obligations of Sprint, Sprint
L.P., Newco, Newco Sub and the Company to consummate the transactions
contemplated by the Investment Agreement (other than the acceptance for payment
of Shares pursuant to the Offer) having been satisfied or waived, including the
expiration or termination of all waiting periods imposed upon consummation of
the Offer and the other transactions contemplated by the Investment Agreement by
the HSR Act, and the absence of any action taken or instituted by the Department
of Justice, the Federal Trade Commission or by any other governmental entity to
delay or otherwise enjoin the transactions contemplated by the Investment
Agreement (collectively, the "Investment Agreement Conditions"). See "Company
Stockholder Vote Matters--Proposal No. 1--Approval of the Merger--Conditions."
 
    In order to induce Sprint and Sprint L.P. to enter into the Investment
Agreement and perform the transactions contemplated thereby, certain members of
management and other stockholders (the "Granting Stockholders") have entered
into an Agreement to Vote and Tender Stock dated February 10, 1998 ("Agreement
to Vote and Tender Stock"). That agreement obligates the Granting Stockholders
to tender all of the 3,989,114 Shares (representing 35.3% of the outstanding
Shares) which they own into the Offer, and to vote those Shares in favor of each
of the Company Stockholder Vote Matters. In order to ensure that the agreement
to vote set forth in the Agreement to Vote and Tender Stock will be fulfilled,
each of the Granting Stockholders granted to Sprint an Irrevocable Proxy,
coupled with an interest, to vote in favor of the Company Stockholder Vote
Matters (the "Irrevocable Proxies"). The Granting Stockholders are Sky Dayton,
Chairman of the Board of the Company, 1,500,000 Shares; Kevin M. O'Donnell, a
Director of the Company, 944,614 Shares; Storie Partners, L.P., 521,892 Shares;
Gregory Abbott, 427,212 Shares; Robert S. London, 392,032 Shares; and George
Abbott, 203,364 Shares.
 
    In addition, certain other stockholders (the "Voting Stockholders") have
entered into an Agreement to Vote Stock dated February 10, 1998 ("Agreement to
Vote Stock") which obligates them to vote all of their 2,950,382 Shares
(representing 26.1% of the outstanding Shares) in favor of the Company
Stockholder Vote Matters, but did not grant any irrevocable proxies thereunder.
The Voting Stockholders are Quantum Industrial Partners LDC, 1,456,480 Shares;
Reed Slatkin, a Director of the Company (through Reed Slatkin & Associates),
1,042,473 Shares; Sidney Azeez, a Director of the Company, 236,884 Shares; and
George Soros, 214,545 Shares.
 
    Based on the foregoing, the Company believes that at least 6,939,496 Shares
(representing 61.4% of the outstanding Shares) will be voted in favor of the
Company Stockholder Vote Matters. The number of Shares obligated to be tendered
and/or voted pursuant to these agreements will ensure approval of the Company
Stockholder Vote Matters, satisfaction of the Minimum Tender Condition, and
consummation of the transactions contemplated by the Investment Agreement,
unless the Investment Agreement Conditions have not been satisfied or waived on
or prior to the Offer Acceptance Time as defined therein. Sprint did not own of
record any Shares as of the Record Date, and therefore is not entitled to vote
at the Special Meeting except insofar as it exercises the Irrevocable Proxies
provided by the Granting Stockholders.

                    DESCRIPTION OF THE INVESTMENT AGREEMENT
 
THE INVESTMENT AGREEMENT
 
    The Investment Agreement provides, among other things, that subject to the
terms and conditions set forth therein, immediately following the consummation
of the Offer, (i) the Merger will be effected and the issued and outstanding
Shares will be converted into the same number of shares of Newco Common Stock;
(ii) Sprint L.P. will acquire 4,102,941 shares of Convertible Preferred Stock,
in exchange for (A) an aggregate cash consideration of $23,750,000, (B) the
assignment to Newco of 100% of the SIP Subscribers, of which there were
approximately 130,000 as of the date of execution of the Investment Agreement,
and (C) Sprint L.P. having entered into the Network Agreement (the issuance of
such Convertible Preferred Stock, "Convertible Preferred Stock Issuance", and
the consideration described in (A), (B) and (C), collectively, the "Convertible
Preferred Stock Consideration"); and (iii) Sprint will provide Newco and the
Company, as co-borrowers, with up to $25 million of convertible senior debt
financing on or after the Closing (as defined below), with such amount to
increase by $25 million on each of the first, second and third anniversaries of
the Closing Date (as defined below) for a total of up to $100 million of such
financing at the end of such period (the "Convertible Debt Financing"), such
indebtedness to be evidenced by one or more Convertible Notes and to be subject
to the terms and conditions of the Credit Agreement."
 
    Consummation of the transactions (other than the Offer) contemplated by the
Investment Agreement is conditioned upon Sprint having accepted for payment the
Shares to be purchased pursuant to the Offer (the "Offer Condition") and the
satisfaction of the HSR Condition (which has now been satisfied), as well as the
other Investment Agreement Conditions. For purposes of the Offer, Sprint will be
deemed to have accepted for payment, and thereby purchased, Shares properly
tendered and not withdrawn as, if and when Sprint gives oral or written notice
to the Depositary of Sprint's acceptance of such shares (the time of giving such
notice is the "Offer Acceptance Time" and the date on which such notice is given
is the "Offer Acceptance Date"). If the Shares have been accepted for payment
pursuant to the Offer, the Offer Acceptance Time will immediately precede the
Closing and the Offer Acceptance Date will occur on the same date as the Closing
Date.
 
    As of the Record Date, there were 12,059,784 Shares issued and outstanding.
Upon consummation of the Offer, Sprint will own approximately 11.1% of such
total number of issued and outstanding Shares (determined as of February 10,
1998), which will be converted into the same number of shares of Newco Common
Stock pursuant to the Merger. As of the Record Date, there were 1,876,860 Shares
reserved for issuance upon the exercise of outstanding employee stock options
("Stock Options") and 675,819 Shares reserved for issuance upon the exercise of
outstanding warrants ("Warrants"). Based upon the conversion price in effect on
the Closing Date, the Convertible Preferred Stock would be convertible into
3,533,411 shares of Newco Common Stock, provided that the Convertible Preferred
Stock may not be converted prior to the first anniversary of the Closing Date.
Based on these figures, immediately after consummation of the Offer, the Merger
and the other transactions contemplated by the Investment Agreement, Sprint
would own approximately 26.6% of the total number of issued and outstanding
shares of Newco Common Stock on a fully diluted basis (that is, assuming that
(i) the Convertible Preferred Stock is converted into Newco Common Stock, and
(ii) that all outstanding Warrants and Stock Options have been exercised.
However, the Convertible Preferred Stock will pay dividends thereon for the
first five years in the form of increases in its Liquidation Value ("Liquidation
Accretion Dividends"), at a per annum rate of 3% of the Liquidation Value, which
will accrue and compound quarterly in arrears, but which will accelerate in the
event of a Business Combination (as defined herein) or an optional redemption by
Newco. At the Closing, the Liquidation Value will be the average of the closing
price per share of Newco Common Stock for the 30 trading days prior to the
Closing Date. Increases in the Liquidation Value will have the effect of
increasing the number of shares of Newco Common Stock which Sprint will receive
upon conversion of the Convertible Preferred Stock. Assuming that the
Convertible Preferred Stock is held by Sprint for the initial five year period,
or the Liquidation Accretion Dividends are accelerated, Sprint will be entitled
to receive 4,102,941 shares of Newco Common Stock upon conversion thereof,
subject to applicable antidilution
 
                                       14
<PAGE>
provisions. If the fully diluted number of Shares, as calculated above, were the
same at that time, Sprint would then own approximately 28.8% of the total number
of issued and outstanding shares of Newco Common Stock on that basis. Such
percentage amount does not take into account the extent to which, if any,
Sprint's fully diluted ownership interest would increase in the event that
advances are made under the Credit Agreement. See "Description of Certain
Ancillary Agreements--The Credit Agreement."
 
    Advances of funds under the Credit Agreement will be evidenced by
Convertible Notes, which are convertible into Newco Common Stock. The Conversion
Price per share at which the Convertible Notes may be converted into Newco
Common Stock is 130% of the average of the closing prices for Newco Common Stock
for the 30 trading days immediately preceding the applicable advance of funds
under the Credit Agreement. Because the number of shares receivable upon
conversion of the Convertible Notes is dependent upon future trading prices for
Newco Common Stock, and because the amount of advances under the Credit
Agreement is within Newco's discretion (provided it is in compliance with
applicable Credit Agreement conditions), it is not possible to predict the
extent to which, if any, Sprint's fully diluted ownership would increase in the
event that advances are made under the Credit Agreement.
 
    Simultaneously with the execution of the Investment Agreement, the following
ancillary Agreements were executed and delivered by the parties thereto: (i) the
Merger Agreement, (ii) the Agreement to Vote and Tender Stock, (iii) the
Agreement to Vote Stock, (iv) the Credit Agreement, (v) the Governance
Agreement, (iv) the Marketing Agreement, (vii) the Network Agreement, (viii) the
Registration Rights Agreement, and (ix) the Stockholders' Agreement. The
agreements referred to in (i), (iv), (v), (vi), (vii), (viii) and (ix) will not
become effective until the Closing and then only if the Offer is consummated and
the Investment Agreement Conditions are satisfied or waived on or prior to the
Closing.
 
    THE MERGER
 
    The Investment Agreement sets forth the parties' agreements with respect to
the Merger. See "Company Stockholder Vote Matters--Proposal No. 1--Approval of
the Merger" for details regarding the Merger.
 
    THE ISSUANCE OF CONVERTIBLE PREFERRED STOCK
 
    Concurrently with the Merger, Sprint L.P. will receive 4,102,941 shares of
Convertible Preferred Stock in exchange for the Convertible Preferred Stock
Consideration. Such consideration consists of (i) $23,750,000 of cash, (ii)
Sprint L.P. contributing the SIP Subscribers to Newco, and (iii) Sprint L.P.,
the Company and Newco entering into the Network Agreement.
 
    The Convertible Preferred Stock will be initially convertible into 3,533,411
Shares of Newco Common Stock at the Closing. Based on these figures, immediately
after consummation of the Offer, the Merger and the other transactions
contemplated by the Investment Agreement, Sprint would own approximately 26.6%
of the total number of issued and outstanding shares of Newco Common Stock on a
fully diluted basis (assuming that all outstanding Warrants and Stock Options
have been exercised, and that the Convertible Preferred Stock has been
converted). However, the Convertible Preferred Stock will pay dividends thereon
for the first five years in the form of increases in its Liquidation Value, at a
per annum rate of 3% of the Liquidation Value), which will accrue and compound
quarterly in arrears, but which will accelerate in the event of a Business
Combination or an optional redemption of the Convertible Preferred Stock by
Newco. At the Closing, the Liquidation Value will be the average of the closing
price per share of Newco Common Stock for the 30 trading days prior to the
Closing Date. Increases in the Liquidation Value will have the effect of
increasing the number of shares of Newco Common Stock which Sprint will receive
upon conversion of the Convertible Preferred Stock. Assuming that the
Convertible Preferred Stock is held by Sprint for the initial five year period,
or the Liquidation Accretion Dividends are accelerated, Sprint will be entitled
to receive 4,102,941 shares of Newco Common Stock upon conversion thereof,
subject to customary antidilution provisions. If the fully diluted number of
Shares, as calculated
 
                                       15
<PAGE>
above, were the same at that time, Sprint would then own approximately 28.8% of
the total number of issued and outstanding shares of Newco Common Stock on that
basis.
 
    Cash dividends at 3% per annum are payable after five years from the Closing
Date when declared by the Board of Directors of Newco out of funds legally
available therefor and such dividends accumulate if not declared and paid. After
the twentieth anniversary of the Closing Date, such cumulative cash dividends
accrue at the rate per annum of 8% of the Liquidation Value, which rate
increases annually by 200 basis points up to an maximum rate of 12% per annum.
Holders of Convertible Preferred Stock are entitled to a liquidation preference
upon any voluntary or involuntary liquidation, dissolution or winding up of
Newco (" Liquidation Event") in an amount per share equal to the sum of (i) the
average closing price per share of Common Stock for the 30 trading days
preceding the Closing Date, (ii) the amount of all Liquidation Accretion
Dividends that have been paid (including an amount equal to a prorated dividend
for the period from the latest Dividend Accrued Date through the date of the
Liquidation Event), and (iii) all accumulations of accrued but unpaid cash
dividends (the sum of (i), (ii) and (iii) is referred to as the Liquidation
Value). Each share of Convertible Preferred Stock initially converts into less
than one share of Newco Common Stock but increases to a one-for-one conversion
(subject, in each case, to customary antidilution adjustments) over a five-year
period.
 
    At Newco's option, the shares of Convertible Preferred Stock are redeemable
after the third anniversary of the Closing Date at a redemption price initially
of 103% of the Liquidation Value and decreasing to 100% of Liquidation Value by
Newco's 2004 fiscal year. The holders of Convertible Preferred Stock may elect
two directors to the Board of Directors of Newco for so long as they hold 20% or
more of Newco's fully diluted shares outstanding (subject to adjustment for
certain dilutive events) and one director for so long as they hold 10% of such
outstanding shares (subject to adjustment for certain dilutive events).
Otherwise, the Convertible Preferred Stock is non-voting except in the limited
circumstances when required under the DGCL.
 
    Consistent with the rights granted in the Governance Agreement, the
Certificate of Designation permits one Investor Director to participate on any
Strategic Business Planning Committee, Finance Committee or other significant
committee of the Board of Directors of Newco, the Company or any other
significant subsidiary, to the extent those committees exist. If there is no
such committee, the holders of Convertible Preferred Stock will have a
reasonable opportunity to review and discuss Newco's strategic and business
plans and financing plans with the management of Newco prior to the submission
of any such plan to the applicable Board or Directors, and to receive advance
copies of information and materials to be provided to such Board of Directors
with respect to such matters. Notwithstanding the foregoing, no Investor
Director is entitled to receive such information or materials or to participate
on any committee of the Board of Directors of Newco, the Company or any
significant subsidiary of Newco created for the purpose of considering a
Business Combination or any matter related thereto (including an "Acquisition
Proposal," a "Sprint Offer" or a "Qualified Offer"), or to participate in the
Board's deliberation with respect to any of the foregoing. See "Description of
Governance Agreement--Corporate Covernance."
 
    ISSUANCE OF CONVERTIBLE NOTES
 
    Concurrent with the Merger, the Credit Agreement will become effective.
Pursuant to the Credit Agreement, Sprint will initially make available up to $25
million in debt financing to the Company and Newco to be evidenced by the
Convertible Notes. Each year after the Closing Date, the aggregate amount that
Sprint is obligated to advance to the borrowers is increased by $25 million to a
maximum of $100 million on a cumulative basis. The Convertible Notes are
convertible into shares of Newco Common Stock at a conversion price of 130% of
the average market price (I.E., the closing sale price over a 30-day trading
period) at the time a particular Convertible Note is issued to evidence an
advance under the Credit Agreement. The Convertible Notes will bear interest at
a rate equal to 6% per annum.
 
                                       16
<PAGE>
    SIP SUBSCRIBERS
 
    Pursuant to the Investment Agreement, concurrently with the Merger, Sprint
L.P. will contribute to Newco all of its SIP Subscribers which at the time of
the execution of the Investment Agreement was approximately 130,000 SIP
Subscribers. Thereafter, the SIP Subscribers shall be subscribers of Newco,
together with all rights under customer contracts and relationships related
thereto. The Investment Agreement provides that if the final number of paid SIP
Subscribers at Closing is less than 130,000, then Sprint L.P. will forfeit to
Newco a number of shares of Convertible Preferred Stock equal to the product of
(i) five, multiplied by (ii) 130,000 less the final number of paid SIP
Subscribers. The contribution of SIP Subscribers is expected to significantly
increase the subscriber base served by Newco.
 
    ACQUISITION PROPOSALS
 
    The Investment Agreement provides that prior to the Closing the Company will
not, nor will it authorize or permit any officer, director or employee, or any
investment banker, attorney or other advisor or representative, of the Company
or any of its subsidiaries to (i) solicit or initiate, or encourage the
submission of, any Acquisition Proposal (as defined herein) or (ii) participate
in any discussions or negotiations regarding, or furnish to any person any
information with respect to, or take any other action to expedite any inquiries
or the making of any proposal that constitutes, or may reasonably be expected to
lead to, any Acquisition Proposal. However, to the extent required by the
fiduciary obligations of the Board of Directors of the Company, as determined in
good faith by the Board of Directors based on the advice of outside counsel, the
Company may, (A) in response to an unsolicited request therefor, furnish
information with respect to the Company to any person pursuant to a customary
confidentiality agreement and discuss such information with such person, (B)
upon receipt by the Company of an Acquisition Proposal, following delivery to
Sprint of the required notice, participate in negotiations regarding such
Acquisition Proposal and (C) modify or withdraw its recommendation that the
stockholders of the Company accept the Offer or its recommendation to such
stockholders that they vote in favor of the transactions contemplated by the
Investment Agreement. Neither the Company nor its Board of Directors may, under
any circumstances, (A) terminate the Investment Agreement or any of the
Ancillary Agreements or withdraw its approval of such agreements, or (B) approve
or authorize the solicitation, initiation or encouragement of additional
Acquisition Proposals. An "Acquisition Proposal" means generally any proposal
for a tender, exchange, merger, recapitalization, liquidation or similar
transaction or any offer or proposal to acquire a material equity interest in or
material amount of voting securities (15% being deemed material for these
purposes) or assets of a party to the Investment Agreement (other than the
transactions contemplated by the Investment Agreement and Ancillary Agreement).
 
    In addition to the obligations of the Company set forth in the preceding
paragraph, the Investment Agreement provides that the Company shall promptly
advise Sprint of the existence of any request for information or of any takeover
proposal, or any inquiry with respect to, or which could lead to, any
Acquisition Proposal.
 
    The Investment Agreement further provides that the Company shall not take
any action that would enhance the ability of any other person proposing a
takeover proposal to obtain the approval of the Company's stockholders or
otherwise consummate such Acquisition Proposal without also taking a comparable
action that would similarly enhance the ability of Sprint to obtain any
necessary approval of the Company's stockholders of, and otherwise to
consummate, the transactions contemplated in the Investment Agreement and the
Ancillary Agreements or an alternative transaction initiated by Sprint and
concurrently withdrawing any impediments thereto that do not similarly impede
such other person.
 
    The Investment Agreement provides that nothing contained therein shall
prohibit the Company from taking and disclosing to its stockholders a position
contemplated by Rule 14e-2 promulgated under the Exchange Act.
 
                                       17
<PAGE>
    TRANSACTION COSTS
 
    The Investment Agreement provides that all fees and expenses incurred in
connection with the Offer, the Investment Agreement and the transactions
contemplated thereby and the Ancillary Agreements shall be paid by the party
incurring such fees or expenses, whether or not the Offer or other transactions
contemplated by the Investment Agreement are consummated. However, one-half of
the reasonable out-of-pocket expenses incurred by the Company in preparing the
Proxy Statement/Prospectus and the S-4 Registration Statement, printing and
mailing the Proxy Statement/Prospectus, the Commission filing fees for the S-4
Registration Statement and in holding the Special Meeting shall be paid by
Sprint.
 
    CONDUCT OF BUSINESS BY THE COMPANY
 
    The Investment Agreement provides that during the period from the date of
the Investment Agreement to the Closing Date, the Company shall carry on its
business in the usual, regular and ordinary course in substantially the same
manner as theretofore conducted and, to the extent consistent therewith, use all
reasonable efforts to preserve intact its current business organizations, keep
available the services of its current officers and other employees and preserve
its relationships with customers, suppliers, licensers, licensees, distributors,
joint ventures and others having business dealings with it except to the extent
that the failure to do so would not have a material adverse effect on the
Company. In addition, during the period from the date of the Investment
Agreement to the Closing Date, the Company shall not, without first consulting
with Sprint take certain material actions relating to, among other matters,
dividends, acquisitions, dispositions, capital issuances or changes in capital
structure, research and development agreements, incurrence of indebtedness,
capital expenditures and satisfaction of claims.
 
    TERMINATION OF THE INVESTMENT AGREEMENT
 
    The Investment Agreement may be terminated at any time prior to the Closing
Date (i) by mutual written consent of the parties thereto, (ii) by any of the
parties if the Offer has not been consummated on or before June 15, 1998, (iii)
by Sprint and Sprint L.P. if any of the conditions to the obligations of Sprint
and Sprint L.P. with respect to Offering shall have become incapable of
fulfillment, and shall not have been waived by Sprint, or (iv) by the Company,
Newco and Newco Sub if any of the conditions precedent to Sprint's right to
consummate the Offer shall have become incapable of fulfillment and shall not
have been waived by the Company, Newco and Newco Sub.
 
    REPRESENTATIONS AND WARRANTIES
 
    The Investment Agreement contains various customary representations and
warranties made by the parties thereto which will not survive the Closing except
for survival thereof for 24 months in the case of fraud or willful material
breaches of such representations and warranties.
 
                    DESCRIPTION OF THE GOVERNANCE AGREEMENT
 
    GENERAL
 
    In connection with the Investment Agreement, Sprint, Sprint L.P., Newco and
the Company entered into the Governance Agreement, which will take effect upon
the Closing. The Governance Agreement establishes certain terms and conditions
concerning the corporate governance of Newco, the acquisition and disposition of
Equity Securities of Newco by Sprint, Sprint L.P. and any of their respective
affiliates (collectively, the "Affiliated Equity Holders"), the rights of Sprint
to make offers to purchase all of the outstanding securities of Newco not owned
by Affiliated Equity Holders and the rights of the Board of Directors of Newco
to receive and entertain offers to effect Business Combinations, all as more
particularly described in the Governance Agreement. The following is a summary
of the Governance Agreement, which is attached hereto as Appendix F and
incorporated by reference herein.
 
                                       18
<PAGE>
    CORPORATE GOVERNANCE
 
    The Governance Agreement establishes that the fundamental policies and
strategic direction of Newco, the Company and any significant subsidiary of
Newco will be determined by their respective Boards of Directors. Consistent
with the voting rights granted to the holders of Convertible Preferred Stock,
the Governance Agreement provides for two individuals to be designated as
"Investor Directors." Similarly, following conversion or redemption of the
Convertible Preferred Stock into Newco Common Stock, Newco and the Company are
obliged to elect the individuals designated as "Investor Directors" to their
respective Boards of Directors. In addition, at such time, the Governance
Agreement permits one Investor Director to participate on any Strategic Business
Planning Committee, Finance Committee or other significant committee of the
Board of Directors of Newco, the Company or any significant subsidiary, to the
extent those committees exist. If there is no such committee, the Governance
Agreement allows Sprint a reasonable opportunity to review and discuss Newco's
strategic and business plans and financing plans with the management of Newco
prior to the submission of any such plan to the Board of Directors, and to
receive advance copies of information and materials to be provided to the Board
of Directors with respect to such matters. Notwithstanding the foregoing, no
Investor Director is entitled to participate on any committee of the Board of
Directors of Newco, the Company or any significant subsidiary created for the
purpose of considering a Business Combination or any matter related thereto
(including an "Acquisition Proposal," a "Sprint Offer" or a "Qualified Offer,"
as described in more detail below), or to participate in the Board's
deliberations with respect to any of the foregoing. Consistent with the terms of
the Convertible Preferred Stock, Sprint is entitled to two Investor Directors
for so long as it holds 20% or more of Newco's fully diluted shares outstanding
(subject to adjustment for certain dilutive events, the "Higher Threshold"), and
one Investor Director for so long as it holds 10% or more of Newco's fully
diluted shares outstanding (subject to adjustment for certain dilutive events,
the "Lower Threshold"). Rights equivalent to those described in this paragraph
are granted to the Investor Directors and the holders of Convertible Preferred
Stock pursuant to the Certificate of Designation. See "Description of the
Investment Agreement--The Investment Agreement--The Issuance of Convertible
Preferred Stock."
 
    At such time as the Convertible Preferred Stock has been converted into
Newco Common Stock, the Governance Agreement obligates Newco to use its best
efforts to solicit from its stockholders proxies in favor of Sprint's Investor
Director nominees. The Governance Agreement also obligates the Affiliated Equity
Holders to vote in favor of any other nominee or director selected by the Board
of Newco in accordance with the agreement. The voting obligations of Affiliated
Equity Holders under the Governance Agreement are supported by an "Irrevocable
Proxy" granted by Sprint and Sprint L.P. to Newco and the Company. See
"--Solicitation of Offers--Stockholders' Agreement; Irrevocable Proxies."
 
    For so long as "Sprint's Percentage Interest" (a term that measures Sprint's
equity stake in Newco, including its ownership of both Newco Common Stock and
Convertible Preferred Stock, as a percentage of Newco's fully-diluted stock
outstanding) is greater than the Lower Threshold, Newco is prohibited by the
Governance Agreement and the Certificate of Designation from taking or
authorizing certain actions without the concurrence of all Investor Directors
serving in such capacity at that time. These actions include (i) the execution
or performance of any "Discriminatory Transaction" (as defined below); (ii) the
issuance of any class or series of stock of Newco that provides for voting
rights in excess of one vote per share; (iii) certain events involving the
dissolution or liquidation of Newco or any subsidiary thereof, or the
commencement by or with respect to Newco or any subsidiary thereof of certain
bankruptcy or bankruptcy-related events or proceedings; (iv) the conduct by
Newco or any significant subsidiary of business substantially outside its
current general field of enterprise; or (v) the issuance by Newco of
"Transaction Securities" (Equity Securities of Newco issued in connection with
joint ventures, strategic alliances, acquisitions, mergers and other business
combination transactions) representing (A) in any twelve-month period, in one or
more transactions, 50% or more of the number of shares of Newco Common Stock
outstanding prior to giving effect to such issuances, or (B) in any one
transaction, 35% or more of the number of shares of Newco Common Stock
outstanding prior to giving effect to such issuance.
 
                                       19
<PAGE>
    The term "Discriminatory Transaction" is defined in the Governance Agreement
as any transaction or corporate action that would (i) impose limitations on the
legal rights of any Affiliated Equity Holder as a stockholder of Newco, (ii)
deny any benefit to any Affiliated Equity Holder, proportionately as a holder of
any class of voting Equity Securities, that is made available to other holders,
or (iii) otherwise materially adversely discriminate against any Affiliated
Equity Holders as stockholders of Newco. However, excepted from the definition
of Discriminatory Transactions are various transactions, including (A) the
adoption and implementation by Newco of a Stockholders' Rights Plan, (B) the
adoption and implementation by Newco of a classified Board of Directors, (C) a
Business Combination if in that transaction (x) neither the Liquidation Value
nor the Conversion Price of the Convertible Preferred Stock is changed, and (y)
upon consummation of such transaction, the holders of Convertible Preferred
Stock are offered the right to receive consideration at the same times, in the
same amount and the same form per share as all other holders of Newco Common
Stock, (D) any transaction having a discriminatory effect against any Affiliated
Equity Holder that occurs as a result of a material breach or violation by any
such holder of the Governance Agreement, and (E) the execution by Newco, the
Company or any significant subsidiary of a definitive agreement with respect to
a Business Combination, if such agreement meets certain requirements set forth
in the Governance Agreement. See "--Purchases of Additional Equity Securities;
Business Combinations."
 
    EQUITY PURCHASES FROM THE COMPANY; SUBSCRIPTION RIGHTS
 
    So long as Sprint's Percentage Interest is greater than an amount defined as
the "Top-Up Threshold" (20%, subject to adjustment for certain dilutive events
and for Newco's incurrence of indebtedness under the Convertible Debt
Financing), the Affiliated Equity Holders have certain anti-dilution and
subscription rights set forth in Article III of the Governance Agreement. In
addition to their rights to subscribe for stock of Newco directly from Newco,
Sprint may effect its rights under Article III by making purchases of Equity
Securities at any time from any person other than Newco as long as, after giving
effect to such purchases, Sprint's Percentage Interest is less than or equal to
the "Pro Rata Share," a formula that limits the maximum equity stake in Newco
that the Affiliated Equity Holders may have. The Pro Rata Share, which adjusts
only upon the incurrence of indebtedness by Newco under the Convertible Debt
Financing, has been established, as of the date of the Governance Agreement, at
an amount equal to .278.
 
    Upon proposing to issue "New Securities" (other than New Securities that are
"Transaction Securities"), if Sprint's Percentage Interest is greater than the
Top-Up Threshold, Newco must provide Sprint written notice of its intent to
effect such issuance at least five business days prior to the date on which the
meeting of the Board is to be held to authorize such issuance. For a period of
ten business days after Sprint's receipt of such notice, Sprint has the right to
purchase the Pro Rata Share of such issuance and, if it does so, the Equity
Securities offered pursuant to such notice shall be issued and sold to Sprint by
Newco at the same times and on the same terms and conditions as the New
Securities are issued and sold to third parties. If for any reason the issuance
of such New Securities to third parties is not consummated, Sprint's right to
purchase its Pro Rata Share of such issuance shall lapse.
 
    As noted above, Sprint's general subscription rights do not apply to the
issuance of Transaction Securities. However, if Newco determines that Sprint's
Percentage Interest has decreased by .05 or more as a result of issuances of
Transaction Securities, Newco must notify Sprint of such event. In addition, not
later than the second anniversary of Sprint's receipt of that notice (the
"Window Period"), Newco is obligated to make written offers (each, a "Primary
Share Offer") to Sprint to purchase, in the aggregate, a number of shares
sufficient to enable Sprint to bring Sprint's Percentage Interest up to the
amount in effect prior to the issuances of Transaction Securities. The number of
shares Newco is obligated to offer pursuant to such provision is defined in the
Governance Agreement as the "Available Top-Up Shares" and the aggregate number
of Available Top-Up Shares resulting from all issuances of Transaction
Securities is defined as the "Aggregate Number of Top-Up Shares." Sprint may
accept a Primary Share Offer within five business days of its receipt thereof,
and the offer is to be made at a purchase price equal to an average stock price
for Newco Common Stock for the ten trading days prior to the date of such
issuance, less the underwriting discount applied in the most recent underwritten
offering of Newco Common Stock.
 
                                       20
<PAGE>
    If Newco determines that Sprint's Percentage Interest has decreased by .10
or more solely as a result of the issuance of Transaction Securities (after
giving effect to any and all Primary Share Offers), the Window Period shall be
accelerated such that Newco shall be obligated to make one or more Primary Share
Offers with respect to not less than the Aggregate Number of Top-Up Shares, as
then calculated, at the earlier of (i) the expiration of the Window Period, as
determined above, or (ii) six months after the date Sprint receives notice to
that effect from Newco. Notwithstanding anything else in the Governance
Agreement to the contrary, in no event is Newco obligated to make Sprint a
Primary Share Offer that, after giving effect to such transaction, would cause
Sprint's Percentage Interest to exceed the Pro Rata Share.
 
    In addition, with respect to a purchase of New Securities pursuant to
Article III of the Governance Agreement, Sprint may, at its option, purchase New
Securities in the form of "Alternative Securities" convertible into the
applicable number of shares of Newco Common Stock. "Alternative Security" is
defined as a new series of Preferred Stock having terms that are structured and
priced in the same manner as the Convertible Preferred Stock. Such terms are
determined, if applicable, by reference to the average stock price for a share
of Newco Common Stock for the 30 trading days prior to the date of issuance of
such Alternative Securities. Sprint's purchase of New Securities in the form of
Alternative Securities are limited (i) to not more than 75% of any issuance of
New Securities from the Closing to the second anniversary thereof, (ii) to not
more than 66.67% of any issuance of New Securities after the second anniversary
of the Closing until the third anniversary thereof and (iii) after the third
anniversary, Newco is not obligated to issue any New Securities in the form of
Alternative Securities.
 
    STANDSTILL PROVISIONS
 
    The Governance Agreement sets forth certain "Standstill Provisions"
applicable to Affiliated Equity Holders. These Standstill Provisions are
summarized below. See "--Solicitation of Offers--Effectiveness; Termination;
Survival" for additional information concerning the survival of the Standstill
Provisions following termination of the Governance Agreement.
 
    Except for purchases of shares and related activities by Sprint otherwise
permitted under the Governance Agreement, the Affiliated Equity Holders may not,
directly or indirectly, (i) acquire, offer to acquire or agree to acquire any
Equity Securities, or any equity securities of any subsidiary of Newco, or
material assets of Newco or any subsidiary or division of Newco; (ii) make or
participate in any "solicitation" of proxies or otherwise seek to influence any
person with respect to the voting of any voting Equity Securities of Newco;
(iii) make any public announcement with respect to, or submit a proposal for, or
offer to effect any purchase of any significant portion of the assets of Newco
or any subsidiary or division of Newco, any tender or exchange offer for any
Equity Securities of Newco, or a merger, consolidation or other extraordinary
transaction involving Newco or any of its Equity Securities; (iv) form, join or
in any way participate in a "group" as defined in Rule 13d-5(b) under the
Exchange Act; or (v) request Newco or any of its representatives to amend or
waive any provision of the foregoing.
 
    In addition, the Affiliated Equity Holders may not, directly or indirectly,
sell, transfer or otherwise dispose of any Equity Securities except (i) pursuant
to a registered underwritten public offering in accordance with the Registration
Rights Agreement, (ii) in accordance with Rule 144 under the Securities Act,
(iii) to any direct or indirect subsidiary of Sprint and (iv) in a transaction
effected in accordance with the so-called "Section 4(1 1/2)" exemption under the
Securities Act. In addition, notwithstanding the foregoing, none of the
Affiliated Equity Holders may sell, transfer or otherwise dispose of any equity
interest in any Equity Securities to any purchaser or group of purchasers if,
after giving effect to such sale, such purchaser or group of purchasers would,
to Sprint's knowledge, own, or have the right to acquire, 5% or more of the
Equity Securities then outstanding, except to any person that is not obligated
(or would not, by virtue of such purchase, reasonably be anticipated to be
obligated) to file a Schedule 13D with the Commission pursuant to each of
paragraphs (b) and (e) of Rule 13d-1 under the Exchange Act.
 
                                       21
<PAGE>
    PURCHASES OF ADDITIONAL EQUITY SECURITIES; BUSINESS COMBINATIONS
 
    Following the 39-month anniversary of Closing and prior to the 63-month
anniversary of Closing (the "Right to Offer Period"), Sprint shall have the
right to make a "Sprint Offer," by offering to purchase all (but not less than
all) of the outstanding Equity Securities that it does not already own at a
price per share equal to the per share price determined by dividing the "Fair
Private Market Value" by the total number of shares of Newco Common Stock
outstanding on a fully-diluted basis. The "Fair Private Market Value" is defined
as the aggregate private market equity value (including control premium) that an
unrelated third party would pay if it were to acquire all of Newco's outstanding
Equity Securities (including Equity Securities held by Affiliated Equity
Holders) in an arm's length transaction, assuming (i) that all credible buyers
are given an equal opportunity by Newco to make and effectuate an Acquisition
Proposal with respect to Newco, (ii) the absence of any commercial relations
between Newco and the Company, on the one hand, and Sprint and its affiliates,
on the other hand, and (iii) the absence of any ownership stake in Newco by
Affiliated Equity Holders. The Fair Private Market Value is to be determined as
follows.
 
    The respective Boards of Newco and Sprint shall negotiate the amount of the
Fair Private Market Value to be paid pursuant to the Sprint Offer. In the event
the two parties are unable to agree on this amount, within 30 days after
submission of the Sprint Offer to the Board, the parties shall agree to be bound
to the valuation arrived at pursuant to the following formula: (i) two
appraisals shall be made by recognized investment banks, one selected by each of
Sprint and Newco (the "Initial Values"), (ii) if the lower of the Initial Values
is more than 10% less than the higher, a third independent valuation will be
made by an investment bank jointly selected by Newco and Sprint (the
"Independent Valuation"); otherwise, the Fair Private Market Value shall be the
average of the Initial Values; and (iii) if the Independent Valuation is greater
or less than the average of the Initial Values by more than 5%, the Fair Private
Market Value shall be deemed to equal the average of the two closest valuations.
If the Independent Valuation does not differ by such amount, it shall be the
Fair Private Market Value.
 
    A Sprint Offer shall not be subject to any financing contingency, and shall
be reflected in a form of definitive agreement that Sprint is prepared to
execute. The conditions to consummation of the Sprint Offer and the
representations and warranties set forth therein shall be reasonable and
customary for transactions in which a similarly situated stockholder offers to
purchase all of the Equity Security not held by such stockholder or its
affiliates.
 
    The Board of Directors of Newco shall have a one-time right, exercisable
within 14 days after receipt of the Sprint Offer, to postpone the making of that
offer for nine months. Upon exercise of such right, Sprint is obligated to
withdraw the Sprint Offer for a period of nine months, provided that (i) the
Right to Offer Period shall be extended to the 72-month anniversary of Closing
and (ii) the exercise by Newco of its postponement right shall not limit
Sprint's right to respond to a "Third-Party Offer" as set forth below.
 
    In addition, upon the determination of the amount of the Fair Private Market
Value, Sprint shall be obligated to commence and effectuate the Sprint Offer,
provided that Sprint shall have a one-time right, exercisable within 14 days
after receipt of the determination of Fair Private Market Value, to determine
not to proceed to make such Sprint Offer. There are, however, certain
limitations on Sprint's exercise of this "Walk-Away Right." If Sprint does not
exercise such right, the Board of Directors of Newco shall, unless an
"Intervening Offer" (as defined below) is then outstanding, (i) support the
Sprint Offer by approving and recommending it to Newco's stockholders and (ii)
cause Newco to take all steps reasonable and necessary to facilitate
consummation of such Sprint Offer. However, at such time as a "Third-Party
Offer" shall constitute an Intervening Offer, Sprint shall be released from its
obligation to commence and effectuate the Sprint Offer, and Newco shall be
released from its obligation to support and facilitate consummation of the
Sprint Offer. If the Intervening Offer is undertaken in the form of a tender
offer, at the consummation of such tender offer, the offeror shall have an
option to purchase from all Affiliated Equity Holders, at the tender offer
price, in the aggregate, a "Specified Number of Equity Securities" (a number of
Equity Securities owned by Affiliated Equity Holders equal to the proportion of
Equity
 
                                       22
<PAGE>
Securities held by unaffiliated equity holders and tendered into or voted for a
competing Business Combination), less the number of Equity Securities that have
already been tendered to such offeror. In addition, if the Intervening Offer (or
a related matter) must be approved by the stockholders of Newco in order for
such offer to be effectuated, the Affiliated Equity Holders are obligated to
cast in favor of the Intervening Offer (and such related matters) such number of
votes as is equal to the Specified Number of Equity Securities, provided that
the Business Combination does not constitute a Discriminatory Transaction.
Affiliated Equity Holders are not entitled to exercise rights of appraisal with
respect to any Business Combination effected in connection with an Intervening
Offer.
 
    The Governance Agreement defines an Intervening Offer as an offer for
aggregate consideration reasonably determined in good faith by the Board of
Newco to be in excess of the aggregate consideration proposed to be paid by
Sprint in a Sprint Offer or a "Qualified Offer" by Sprint (as defined below), as
applicable. The conditions to consummation of an Intervening Offer and the
representations, warranties and covenants set forth in the Intervening Offer
shall be customary for a transaction of that type.
 
    THIRD-PARTY OFFERS
 
    Newco 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 ("Offer"). Upon receipt of such Offer, the Board is to determine
whether it intends to recommend that offer to the stockholders (a "Recommended
Third-Party Offer") or that such offer is not in the best interests of Newco's
stockholders, in which event it intends not to recommend such offer to the
stockholders (a "Non-Recommended Third-Party Offer" and, together with a
Recommended Third-Party Offer, a "Third-Party Offer").
 
    For a period of ten days following the giving of notice of receipt of an
Offer, Newco may not enter into a definitive Agreement with respect to that
Offer. Sprint has an option to make a "Qualified Offer" with respect to either
(i) an Offer that is a Recommended Third-Party Offer or (ii) an Offer that is a
Non-Recommended Third-Party Offer if the Board of Sprint reasonably determines
that the conditions to the Non-Recommended Third-Party Offer are reasonably
likely to be satisfied and the Offer consummated. A "Qualified Offer" is defined
as an offer made by an Affiliated Equity Holder to acquire all of the Equity
Securities not already owned by the Affiliated Equity Holders at a price per
share in excess of the equivalent per share price set forth in a Third-Party
Offer or an Intervening Offer, as the case may be. A Qualified Offer shall be
reflected in a form of definitive agreement that Sprint is prepared to execute,
and the conditions to consummation of such offer and the representations,
warranties and covenants set forth in it shall be customary for transactions in
which a similarly situated stockholder offers to purchase all of the Equity
Securities not held by such stockholder and may not, in any event, be more
onerous in any material respect than those set forth in the Third-Party Offer or
the Intervening Offer, as the case may be.
 
    Newco may not adopt any takeover defenses, enter into any agreement or take
any other action in connection with a Recommended Third-Party Offer that would
materially impair Sprint's ability to make and consummate a Qualified Offer or
materially increase Sprint's cost of consummating a Qualified Offer. However,
notwithstanding the foregoing, Newco is permitted to enter into a definitive
agreement with respect to a Recommended Third-Party Offer that provides for a
termination fee not to exceed 3% of the consideration to be received per share
of Newco Common Stock multiplied by the number of shares of Newco 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 such Recommended Third-Party Offer must
provide that such fees and expenses shall not be payable if Sprint makes a
Qualified Offer within 72 hours of the first public announcement of such
Recommended Third-Party Offer.
 
    If Sprint has the option to make a Qualified Offer and does so more than
five days prior to the date of a stockholders' meeting held to consider a
Third-Party Offer or an Intervening Offer, the Board of Directors shall, unless
an Intervening Offer is then outstanding, support the Qualified Offer by
approving
 
                                       23
<PAGE>
and recommending it to Newco's stockholders and cause Newco to take all steps
reasonable and necessary to facilitate consummation of the Qualified Offer.
However, at such time as a Third-Party Offer made subsequent to a Qualified
Offer shall constitute an Intervening Offer, Newco's obligations to support and
facilitate a Qualified Offer shall terminate and Newco shall be free to consider
and act upon such Intervening Offer. Sprint is nonetheless entitled, at any time
prior to consummation of the Intervening Offer, to make another Qualified Offer,
and in such event, the most recent Third-Party Offer shall cease to constitute
an Intervening Offer.
 
    If a Recommended Third-Party Offer or an Intervening Offer is undertaken in
the form of a tender offer, at the consummation of such tender offer, the
offeror shall have an option, to purchase from all Affiliated Equity Holders, at
the tender offer price, in the aggregate, a Specified Number of Equity
Securities, less the number of Equity Securities that have already been tendered
to such offeror. In addition, if a Recommended Third-Party Offer or an
Intervening Offer, as the case may be (or a related matter) must be approved by
the stockholders of Newco in order for such offer to be effectuated, the
Affiliated Equity Holders are obligated to cast in favor of such offer (and such
related matter) such number of votes as is equal to the Specified Number of
Equity Securities, provided that the Business Combination does not constitute a
Discriminatory Transaction. Affiliated Equity Holders are not entitled to
exercise rights of appraisal with respect to any Business Combination effected
in connection with a Recommended Third-Party Offer or Intervening Offer.
 
    The Governance Agreement defines "Business Combination" to mean a
transaction, undertaken in any form whatsoever, involving (i) the purchase or
acquisition of Equity Securities if the consummation of such transaction would
result in the purchaser beneficially owning 35% or more of the Equity Securities
outstanding, or (ii) a merger, consolidation, combination or other extraordinary
transaction with respect to Newco in which, upon consummation thereof, the
shareholders or owners of the other entity that is a party thereto, or the
controlling persons thereof, would acquire beneficial ownership of 50% or more
of the Equity Securities outstanding. The term Business Combination includes a
"Significant Sale," which means the sale of assets of Newco or any subsidiary or
the sale of capital stock of any subsidiary by Newco, in any such case, for
which the consideration proposed to be paid in such transaction represents 35%
or more of the market capitalization of Newco on the date that Newco agrees to
such sale.
 
SOLICITATION OF OFFERS
 
    From the Closing Date until the earlier of the 27-month anniversary of such
date or the termination of the Governance Agreement in accordance with its
terms, Newco may not, directly or indirectly, (i) solicit or initiate, or
encourage the submission of, any "Acquisition Proposal" (as defined below), or
(ii) participate in any discussions or negotiations regarding, or take any
action that may reasonably be expected to lead to any Acquisition Proposal.
However, to the extent required by the fiduciary obligations of the Board of
Directors, as determined in good faith by the Board based on the advice of
outside counsel, Newco may (A) furnish information in response to any
unsolicited requests therefor and discuss such information, (B) upon receipt by
Newco of an Acquisition Proposal, following delivery to Sprint of notice
thereof, participate in negotiations regarding such Acquisition Proposal and (C)
enter into an agreement respecting such Acquisition Proposal or any related
agreements or take any other action ancillary thereto.
 
    After the 27-month anniversary of the Closing Date until the 39-month
anniversary thereof or the termination of the Governance Agreement in accordance
with its terms, Newco may not, directly or indirectly, take any of the actions
identified in the prior paragraph except through an investment banking firm
formally engaged by Newco for such purpose; provided, that, 30 days prior to so
engaging such investment banking firm for that purpose, Newco shall notify
Sprint of its intention to effect such engagement, and Sprint shall be permitted
to prepare and make a Sprint Offer for so long as such investment banking firm
remains engaged by Newco for that specific purpose. Subject to the terms and
conditions of the Sprint Offer and unless an Intervening Offer is then
outstanding, Sprint is entitled to pursue any such Sprint Offer for so long as
necessary to permit it to be consummated. Newco is obligated
 
                                       24
<PAGE>
to furnish Sprint with copies of all information provided by Newco to such
investment banking firm at the time such information is provided to such firm,
subject to Sprint entering into a customary confidentiality agreement with
respect to that information.
 
    The Board of Directors of Newco is obligated to (i) promptly notify Sprint
in writing of (A) its receipt of an Acquisition Proposal, (B) any inquiries or
discussions that may reasonably be expected to lead to an Acquisition Proposal,
(C) the execution by Newco of a confidentiality agreement with respect to an
Acquisition Proposal or (D) the furnishing of any confidential information in
contemplation of an Acquisition Proposal, whether or not pursuant to a
confidentiality agreement; (ii) describe the terms and conditions of any
Acquisition Proposal in reasonable detail; (iii) provide to Sprint copies of any
definitive agreements with respect to any Acquisition Proposal and any
confidentiality agreements with respect thereto; and (iv) subject to Sprint's
obligation to hold such information in strict confidence, make available to
Sprint all information made available to the party making the Acquisition
Proposal at the same time it is provided to such party.
 
    An "Acquisition Proposal" means any proposal for a tender or exchange offer,
a merger, consolidation, share exchange or other business combination, in which
Newco is a constituent party to such transaction, or a sale of securities (other
than Transaction Securities), recapitalization, liquidation, dissolution or
similar transaction involving Newco, or any proposal or offer to acquire in any
manner, directly or indirectly, a material equity interest in, or a material
amount of voting securities (with the acquisition of beneficial ownership of 20%
or more of the voting Equity Securities being deemed to be material for this
purpose) or assets of, Newco. In addition, a "Material Sale," defined as any
proposal involving the sale of assets of Newco or any subsidiary or the sale of
capital stock of any subsidiary, in any such case, for which the consideration
proposed to be paid in such transaction represents 20% or more of the market
capitalization on the date that Newco receives such proposal, is also defined as
an Acquisition Proposal.
 
    Subject to certain exceptions, Newco is obligated under the Governance
Agreement not to take any action or omit to take any action that would result in
(i) any Affiliated Equity Holder being deemed an "Acquiring Person" or similar
designation under any Stockholders' Rights Plan, (ii) any Affiliated Equity
Holder being prejudiced under any applicable state takeover statute, including
Section 203 of the DGCL, or (iii) otherwise causing any takeover defense to
materially impair or obstruct, or prevent (either legally or financially) the
exercise by any Affiliated Equity Holder of rights granted under Article IV of
the Governance Agreement.
 
    STOCKHOLDERS' AGREEMENT; IRREVOCABLE PROXIES
 
    In order to provide for enforcement of certain aspects of the Governance
Agreement, Sprint and certain principal stockholders of the Company entered into
the Stockholders' Agreement. Further, in order to provide for enforcement of the
Stockholders' Agreement and certain other provisions of the Governance Agreement
requiring the Affiliated Equity Holders to vote their voting Equity Securities
in a certain manner, Sprint and Sprint L.P. have provided an Irrevocable Proxy
to the Company and Newco. See "Description of Certain Ancillary
Agreements--Stockholders' Agreement."
 
    EFFECTIVENESS; TERMINATION; SURVIVAL
 
    The Governance Agreement becomes effective at the Closing. Thereafter, the
Governance Agreement terminates at the earliest of the following to occur: (i)
the termination of the Investment Agreement in accordance with its terms; (ii)
such time as Sprint's percentage interest is greater than 90% or less than the
Lower Threshold; (iii) the expiration of the Right to Offer Period; (iv) the
first date on which any Person or group as defined in Rule 13d-5(b) of the
Exchange Act is determined (A) to beneficially own or control more than 35% of
the Equity Securities outstanding by virtue of the acquisition of such
securities pursuant to a Third-Party Offer if the rights granted and process
contemplated by Article IV of the
 
                                       25
<PAGE>
Governance Agreement have been effected in accordance with the terms thereof or
(B) to beneficially own or control 50% or more of the voting Equity Securities
outstanding; (v) upon the termination of the Marketing Agreement in accordance
with certain of its provisions; or (vi) upon the exercise of registration rights
(demand or incidental) by any "Holder" of "Registrable Securities" under the
Registration Rights Agreement.
 
    Notwithstanding the termination of the Governance Agreement, until the sixth
anniversary of the Closing Date and thereafter for as long as Sprint's
percentage interest is greater than the Lower Threshold, Sprint shall still be
subject to the Standstill Provisions. In addition, for so long as Sprint's
Percentage Interest remains greater than the Lower Threshold, Sprint shall still
have certain governance and anti-dilution rights under the Governance Agreement.
In such event, the Standstill Provisions and such other provisions (as well as
any definitional provisions with respect to the foregoing) shall remain in full
force and effect until such time as Sprint's Percentage Interest is lower than
the Lower Threshold; provided, however, that during any period in which the
Standstill Provisions survive, Sprint and its affiliates may directly approach
the Board of Newco in order to make an offer to effect a Business Combination.
 
                  DESCRIPTION OF CERTAIN ANCILLARY AGREEMENTS
 
    The following are descriptions of certain Ancillary Agreements entered into
by the Company and/or Newco in connection with the transactions contemplated by
the Investment Agreement.
 
CREDIT AGREEMENT
 
    In connection with the Investment Agreement, the Company and Sprint entered
into the Credit Agreement, which will become effective concurrently with the
Merger. Under the Credit Agreement, Sprint will initially provide up to $25
million in debt financing to be evidenced by the Convertible Notes. Each year
after the Closing Date, the aggregate amount that Sprint is obligated to advance
will be increased by $25 million to a maximum of $100 million on a cumulative
basis. The Convertible Notes are convertible into shares of Newco Common Stock
at a conversion price of 130% of the average fair market price (i.e., the
closing sales price over a 30 trading day period) at the time a particular
Convertible Note is issued to evidence an advance under the Credit Agreement.
Each Convertible Note will mature five years from the date of issuance and will
bear interest at a rate equal to 6% per annum. The Company presently does not
intend to incur indebtedness under the Credit Agreement.
 
    Sprint's obligations to make advance under the Credit Agreement terminates
upon the earlier of (i) the fifth anniversary of the Closing Date, (ii)
acceleration of the indebtedness evidenced by the Convertible Notes upon an
Event of Default (as defined below), (iii) consummation of a Business
Combination (as defined below), or (iv) termination of the Marketing Agreement
pursuant to certain provisions thereof. An Event of Default shall occur if (i)
there is a breach or there are breaches of any of the representations or
warranties unless such breach or breaches would not in the aggregate have a
Material Adverse Effect on Newco, the Company and their subsidiaries, taken as a
whole, (ii) nonpayment of principal or interest within 14 days after the same
becomes due, (iii) a breach of certain financial and other convenants, and in
certain cases, a failure to cure such breach within the applicable cure period,
(iv) a default by Newco or the Company in any agreement or agreements under
which indebtedness in excess of $5 million was created, or the occurrence of any
other event or existence of any condition, the effect of any of which causes, or
permits the holder of such indebtedness to cause, such indebtedness to become
due prior to its stated maturity, or any such indebtedness shall be declared due
and payable prior to the stated maturity thereof, (v) Newco or the Company files
for relief under bankruptcy, receivership or similar laws, or fails to contest
any involuntary petition in bankruptcy filed with regard to Newco or the
Company, (vi) any condemnation of a substantial portion of the property of Newco
or the Company, or (vii) Newco or the Company fails within 30 days to pay, bond
or otherwise discharge any judgments or orders for the payment of money in
excess of $1 million, which are not stayed on appeal or otherwise contested in
good faith. "Material Adverse Effect" is defined to mean any change or effect
having a
 
                                       26
<PAGE>
material adverse effect (or any development as to which there is a substantial
likelihood, insofar as can be foreseen, that would have such an effect) on the
business, properties, assets, condition (financial or otherwise) or results of
operations of the Company, Newco, Newco Sub, Sprint, Sprint L.P. and Sprint's
subsidiaries, as the case may be.
 
REGISTRATION RIGHTS AGREEMENT
 
    Newco and Sprint have entered into the Registration Rights Agreement with
respect to Newco Common Stock held by Sprint. Under the Registration Rights
Agreement, Sprint has the right (the "Demand Registration Right") to at any time
require Newco to file up to four registration statements under the Securities
Act to effect the registration of Newco Common Stock held by Sprint. This right
may be exercised after 27 months following the Closing Date, but only once every
nine months. Expenses relating to the exercise of the Demand Registration Right
will generally be payable by Newco.
 
    Under the Registration Rights Agreement, Sprint also has the right (the
"Incidental Registration Right"), with respect to any underwritten offerings,
including registered offerings, of Newco Common Stock for cash proposed by
Newco, to require Newco to include Newco Common Stock of Sprint in such offering
and registration, if applicable after 27 months following the Closing Date.
Incremental expenses relating to exercises of the Incidental Registration Right
will generally be payable by Newco. In other respects, the Registration Rights
Agreement contains terms that are customary to registration rights agreements of
its type.
 
MARKETING AGREEMENT
 
    Concurrently with the Merger, the Marketing Agreement among Sprint, Sprint
L.P., Newco and the Company will become effective, whereby certain cooperation
and support will be provided to each other in specified marketing matters and
Sprint L.P. will grant to Newco and the Company the right to utilize certain
distribution channels of Sprint. Sprint will also license the use of its brand
to Newco and the Company, and Newco and the Company will agree to use such brand
in conjunction with the Company's brand in the business of the Company, subject
to specified terms and conditions. The Marketing Agreement applies only to the
parties' activities in the 48 contiguous states of the United States (the
"Territory").
 
    Pursuant to the Marketing Agreement, Sprint has appointed Newco and its
controlled affiliates as agents to sell Sprint's long distance services and
certain other telecommunications services as are agreed to by the parties. In
addition, Newco has appointed Sprint and its subsidiaries as agents to sell
Internet-related services offered by Newco and its controlled affiliates. The
Marketing Agreement provides for a joint marketing committee.
 
    The Marketing Agreement also contains certain exclusivity arrangements. The
Marketing Agreement restricts Sprint and its controlled affiliates from
promoting, advertising, marketing, co-branding, packaging, bundling, developing,
offering or selling, or entering into any express or tacit agreement to permit
its name to be used in connection with, a set of Internet-related products and
services (whether as a series of individual products and services or as an
integrated grouping or package of products and services) that is the same as or
substantially similar to the Company's core Internet service package (the "Core
Internet Application Set"), as in effect from time to time, other than as
offered by Newco and its controlled affiliates. Sprint and its controlled
affiliates further agree that they will not bid on, acquire or directly or
indirectly own, manage, operate, join, control or finance, or participate in the
management, operation, control or financing of, any provider of any set of
Internet-related products and services that is the same as or substantially
similar to the Core Internet Application Set (as in effect from time to time).
The Marketing Agreement specifies that these exclusivity restrictions do not
restrict Sprint and its controlled affiliates from (i) appointing one or more
other Internet service providers ("ISP's") as Sprint's agents for the sale of
its branded long distance services and telecommunications services so long as
the Internet-
 
                                       27
<PAGE>
related services provided by such ISP are not billed on an integrated basis with
any services provided by Sprint, (ii) providing Internet service packages that
are designed primarily for large corporate accounts and offering enhanced
features that are not included in the Core Internet Application Set and (iii)
offering or selling individual components that are included in the Core Internet
Application Set so long as the Company has a first right of refusal to provide
Sprint with such elements or components.
 
    Newco and its controlled affiliates are restricted from promoting,
advertising, marketing, co-branding, bundling, developing, offering or selling
any long distance services or telecommunications services that are the same as
or substantially similar to the long distance services or telecommunications
services offered by Sprint and its controlled affiliates, other than as offered
by Sprint and its controlled affiliates. Newco and its controlled affiliates are
further prohibited from bidding on, acquiring or directly or indirectly owning,
managing, operating, joining, controlling or financing, or participating in the
management, operation, control or financing of, or acting as an agent or
representative for, or entering into any express or tacit agreement to permit
its name to be used in connection with, or permit its Internet services to be
marketed, sold or distributed by, any "Material Provider" of long distance
services or telecommunication services other than Sprint and its controlled
affiliates. A business or entity is deemed to be a "Material Provider" of long
distance services or telecommunications services if such business or entity
(together with its affiliates) derives from the sale of long distance services
and certain telecommunications services (i) more than 5% of its gross revenues
in any fiscal year or (ii) more than $25 million of gross revenues in any fiscal
year. The exclusivity restrictions will restrict Newco and its controlled
affiliates with respect to PCS and cellular services only if Sprint PCS enters
into sales agency relationships with Newco and its controlled affiliates on the
terms set forth in the Marketing Agreement. Newco and its controlled affiliates
are not prohibited from (i) continuing to offer a co-branded Core Internet
Application Set under currently existing agreements (subject to certain
restrictions), (ii) offering Internet telephony services under certain
circumstances, provided that Sprint has the first right to provide that service
at such time as it has developed an Internet telephony product and (iii) selling
ATM and frame relay telecommunications services of a third party for the sole
purpose of providing access to the public Internet.
 
    Sprint and its controlled affiliates will seek to generate customers for the
Company's Core Internet Application Set through Sprint's customer base and its
third party marketing channels. The Company will pay Sprint varying amounts for
each customer generated by Sprint. In addition, Sprint is obligated to pay
varying shortfall amounts if Sprint fails to generate a minimum of 150,000 new
subscribers per year for the Core Internet Application Set in any year during
the five-year period commencing September 1, 1998. Newco and its controlled
affiliates will seek to generate customers for Sprint's long distance and other
telecommunications services from the users of its Core Internet Application Set.
Newco and its controlled affiliates will be entitled to payment from Sprint of a
market rate commission based on the monthly revenue generated from such
customers.
 
    The Company and Sprint have agreed to negotiate a billing and collection
agreement for integrated billing services for Sprint's long distance and
telecommunications services and the Company's Internet services. The Company
will also cooperate with Sprint in developing Internet-related developments and
enhancements that are requested by Sprint.
 
    Sprint and the Company have agreed to use the "EarthLink-Sprint" co-brand in
all of Sprint's marketing, advertising and other similar material relating to or
referencing any of the Company's Internet services and in all of the Company's
marketing, advertising and other similar material used to promote and offer for
sale or otherwise relating to its Internet services and/or Sprint's long
distance services and telecommunications services. Each party has extended to
the other a non-exclusive, royalty-free, non-transferable license to use its
brand in the Territory to the extent described above.
 
    The Marketing Agreement has a 10-year term and may be extended by either
party for an additional five years. The Agreement is subject to early
termination upon the occurrence of certain events, including (i) a change of
control of Sprint or Newco, (ii) a business combination between Sprint and an
entity
 
                                       28
<PAGE>
engaged in a business that is competitive with the Company's Core Internet
Application Set, (iii) the termination of the Governance Agreement under certain
circumstances and (iv) a material breach by either party that is not cured after
notice. Upon termination of the Marketing Agreement under the circumstances
described in clause (ii) above, Sprint will be required to pay a termination fee
to the Company, which will equal $60 million if such termination occurs during
the first two years following the Merger, dropping to $36 million on the day
following the second anniversary of the Merger and thereafter declining on a
daily pro rata basis to zero on and after the fifth anniversary of the Merger.
In case of such termination, Sprint must also pay an additional fee (up to a
maximum of $17.5 million, but declining to zero after five years) to compensate
the Company for the loss of customers that would have been generated for the
Company through Sprint's marketing channels. The termination fee described above
represents the sole amount that will be payable by either party upon a
termination of the Marketing Agreement, except for payment obligations accrued
prior to termination and damages from the party's breach of the Marketing
Agreement.
 
NETWORK AGREEMENT
 
    Concurrently with the Merger, the Network Agreement between and among Sprint
L.P., Newco and the Company will become effective, whereby Sprint L.P. agrees to
provide, and Newco and the Company agree to utilize, certain dial-up Internet
access ports ("Ports") for use by the Company's Internet dial-up access
customers. The Network Agreement provides for the provision of a minimum number
of Ports together with the option for the Company to order an additional
quantity of Ports over the initial minimum term of four years.
 
    The Network Agreement sets forth the schedule for implementation of service
in locations and in such quantities as agreed to by the parties. The Network
Agreement also specifies the rates and charges for the use of the Ports during
the initial term and a process for negotiating continued use of the Ports beyond
the initial term. The Network Agreement describes the performance parameters
associated with the Ports and allocates responsibilities for network and
customer support activities between the parties. In addition, the Network
Agreement specifies other commercial terms customarily found in network service
agreements, such as payment terms, FORCE MAJEURE and governing law.
 
AGREEMENT TO VOTE AND TENDER STOCK; AGREEMENT TO VOTE STOCK
 
    In order to induce Sprint and Sprint L.P. to enter into the Investment
Agreement and perform the transactions contemplated thereby, the Granting
Stockholders (certain members of management and other stockholders) have entered
into the Agreement to Vote and Tender Stock. That agreement obligates the
Granting Stockholders to tender all of the 3,989,114 Shares (representing 35.3%
of the outstanding Shares) which they own into the Offer, and to vote those
Shares in favor of each of the Company Stockholder Vote Matters. In order to
ensure that the agreement to vote set forth in the Agreement to Vote and Tender
Stock will be fulfilled, each of the Granting Stockholders granted to Sprint an
Irrevocable Proxy, coupled with an interest, to vote in favor of the Company
Stockholder Vote Matters. The Granting Stockholders are Sky Dayton, Chairman of
the Board of the Company--1,500,000 Shares; Kevin M. O'Donnell, a Director of
the Company--944,614 Shares; Storie Partners, L.P.--521,892 Shares; Gregory
Abbott--427,212 Shares; Robert S. London--392,032 Shares; and George
Abbott--203,364 Shares.
 
    In addition, the Voting Stockholders have entered into the Agreement to Vote
Stock which obligates them to vote all of their 2,950,382 Shares (representing
26.1% of the outstanding Shares) in favor of the Company Stockholder Vote
Matters, but did not grant any irrevocable proxies thereunder. The Voting
Stockholders are Quantum Industrial Partners LDC--1,456,480 Shares; Reed
Slatkin, a Director of the Company (through Reed Slatkin & Associates)--
1,042,473 Shares; Sidney Azeez, a Director of the Company--236,884 Shares; and
George Soros--214,545 Shares.
 
                                       29
<PAGE>
    Based on the foregoing, the Company believes that at least 6,939,496 Shares
(representing 61.4% of the outstanding Shares as of February 10, 1998) will be
voted in favor of the Company Stockholder Vote Matters. The number of Shares
obligated to be tendered and/or voted pursuant to these agreements will ensure
approval of the Company Stockholder Vote Matters, satisfaction of the Minimum
Tender Condition, and consummation of the transactions contemplated by the
Investment Agreement, unless the Investment Agreement Conditions have not been
satisfied or waived on or prior to the Offer Acceptance Time, as described
therein and herein. Sprint did not own of record any Shares as of the Record
Date, and therefore is not entitled to vote at the Special Meeting except
insofar as it exercises the Irrevocable Proxies provided by the Granting
Stockholders.
 
STOCKHOLDERS' AGREEMENT
 
    In connection with the Investment Agreement, Sprint and certain principal
stockholders of the Company (the "Covered Stockholders") entered into the
Stockholders' Agreement, which will become effective at Closing. The
Stockholders' Agreement obligates the Covered Stockholders to support the
obligations of Newco under the Governance Agreement by (i) voting all of the
"Covered Shares" (as defined in the Stockholders' Agreement) in favor of a
Sprint Offer or a Qualified Offer and (ii) tendering all of the Covered Shares
into a tender offer initiated by Sprint to effect a Sprint Offer or a Qualified
Offer, unless, in each case, an Intervening Offer is then outstanding. The term
"Covered Shares" includes Shares, shares of Newco Common Stock received in the
Merger and other Equity Securities. However, it does not include shares of Newco
Common Stock or other Equity Securities subsequently sold by the Covered
Stockholders in accordance with the terms of the Stockholders Agreement. The
name and number of Covered Shares held by each Covered Stockholder is as
follows: Sky Dayton, Chairman of the Board of Directors of the Company--
1,500,000 Shares; Quantum Industrial Partners LDC--1,456,480 Shares; Reed
Slatkin, a Director of the Company (through Reed Slatkin &
Associates)--1,042,473 Shares; Kevin M. O'Donnell, a Director of the
Company--944,614 Shares; Sidney Azeez, a Director of the Company--236,884
Shares; and George Soros--214,545 Shares.

                    RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Board of Directors of the Company has, by unanimous vote of all
Directors, approved the Offer, the Merger and all the other transactions
contemplated by the Investment Agreement, including without limitation the
Company Stockholder Vote Matters, and determined that the terms of such
transactions, when taken together, are fair to, and in the best interests of,
the stockholders of the Company. ACCORDINGLY, THE BOARD OF DIRECTORS UNANIMOUSLY
RECOMMENDS THAT STOCKHOLDERS OF THE COMPANY TENDER THEIR SHARES OF COMMON STOCK
IN THE OFFER AND VOTE FOR EACH OF THE COMPANY STOCKHOLDER VOTE MATTERS.
 
BACKGROUND OF RECOMMENDATION
 
    During August, September and October of 1997, the Company's senior
management analyzed the Company's strategic position in the Internet industry
and its prospects for continuing and accelerating the growth of its business and
achieving critical mass in its subscriber base and greater scale in its
operations. In light of this analysis, management discussed with the Company's
Board of Directors (on both a formal and an informal basis) an array of
strategic alternatives designed to enhance the Company's strategic, operational,
financial, marketing and distribution capabilities.
 
    At a regular meeting of the Board of Directors of the Company held on
October 29, 1997, the Board conducted an open-ended discussion of these
alternatives, which included (i) a proposed strategic alliance with Sprint; (ii)
an underwritten equity offering or other financing transactions; (iii) a
significant infusion of equity capital by a financial investor, the proceeds of
which would be used by the Company to make strategic acquisitions; (iv) a
significant equity investment in the Company by, and/or a joint venture
involving the Company with, one or more Regional Bell Operating Companies; and
(v) either alone or in combination with certain of the foregoing, the making of
a business combination proposal to one or more other providers of Internet
services. At the conclusion of this discussion, the Board did not recommend that
any particular alternative be pursued to the exclusion of others, but rather
directed that management take further steps to explore the availability of
various options (without committing the Company to any alternative without
further action of the Board) and periodically report to the Board on the results
of such initiatives. The Board also authorized senior management and the
Company's financial advisor, DMG, to make selective inquiries to determine
whether certain firms in the telecommunications industry would have any interest
in a potential joint venture, strategic alliance or minority investment
relationship with the Company. The Board also instructed management and DMG not
to foreclose the possibility of a business combination involving the Company,
although it believed that the better approach, in terms of enhancing the
Company's long-term value, was to solicit a strategic alliance or minority
investment. Ultimately, no proposals to effect a business combination emerged.
As a result of management's exploratory initiatives, based on the strategic,
operational and financial considerations described below and Sprint's dynamic
and prompt expression of interest in pursuing a strategic alliance with the
Company, the Board determined that focusing primarily on the Sprint alternative
was most likely to produce the best transaction reasonably available.
 
    During early October 1997, with the permission of Garry Betty, President and
Chief Executive Officer of the Company, Sidney Azeez, one of the Company's
directors, contacted Carl Peterson, General Manager, President and CEO of the
Kansas City Chiefs, inquiring whether he was acquainted with William T. Esrey,
Chairman and Chief Executive Officer of Sprint Corporation. After learning that
Mr. Peterson and Mr. Esrey were acquaintances, Mr. Betty requested that Mr.
Peterson arrange an introduction so the Company could explore whether Sprint
would have any interest in discussing the possibility of a strategic alliance or
other relationship. Mr. Peterson contacted Sprint and suggested a meeting during
which the companies could discuss their respective businesses and the possible
benefits of a strategic or other relationship.
 
    Theodore H. Schell, Senior Vice President Strategic Planning & Corporate
Development, phoned Mr. Betty on October 8, 1997 to express Sprint's interest in
exploratory discussions and to arrange for a
 
                                       31
<PAGE>
visit by a Sprint representative to the Company's headquarters in Pasadena,
California. On October 10, 1997, Chuck Chakravarty, Manager Corporate
Development, visited the Company's headquarters in Pasadena, California and had
discussions with Mr. Betty and other members of the Company's management. The
discussions focused on the operational and financial aspects of the Company.
 
    On October 29, 1997, Sprint and the Company executed a reciprocal
confidentiality agreement in which they agreed to maintain the confidentiality
of nonpublic information concerning their businesses. On October 31, 1997, Mr.
Schell, Timothy S. Sutton, Vice President Strategic Planning--Corporate
Development and James Dodd, Vice President Internet Access Services met with Mr.
Peterson, Sky Dayton, Chairman of the Board of the Company, and Mr. Betty in
Kansas City to obtain a strategic overview of the Company's business. Following
that discussion, the participants concluded that there were several areas of
shared perspective with regard to the importance of expanded scale in the
Internet access business, the technological evolution of the Internet, and
business philosophies regarding quality of customer service and operations.
 
    In early November 1997, Mr. Sutton and Mr. Betty had phone conversations
confirming the desire of both parties to engage in further exploration of a
strategic or other relationship. On November 19, 1997, Mr. Sutton, Mr. Dodd and
certain other officers and employees of Sprint met in Pasadena with Mr. Dayton,
Mr. Betty and certain other officers and employees of the Company, and
representatives of DMG. The Company's representatives presented a high-level
overview of the Company's business from an operational, financial and strategic
perspective. The participants then engaged in a high-level discussion of
possible alternatives for a strategic or other relationship between Sprint and
the Company. Sprint's representatives discussed the factors of importance to
Sprint in assessing a potential relationship with the Company. These factors
included continued reliance on the Sprint brand (either alone or co-branded with
the Company's brand); marketing rights to the Internet product; utilization of
Sprint's network services; and the financial implications of the nature and
amount of the investment requisite to scaling up to achieve critical mass and
profitability. Each party expressed the desire to consider commercial alliances
as opposed to a business combination or similar type of transaction with the
other party at the time. However, each party expressed an interest in Sprint
acquiring a minority equity interest in the Company if a structure could be
developed that would be acceptable from a strategic, operational and financial
point of view.
 
    Additional meetings were held in Pasadena on November 21 and 22, 1997 among
officers and employees of Sprint and the Company to continue discussions of the
strategic, financial and operational characteristics of a strategic relationship
between Sprint and the Company with respect to their Internet businesses. The
possible marketing opportunities and synergies of such an alliance were also
explored. These meetings were followed by several telephone calls between
officers of Sprint and the Company with regard to these matters.
 
    A meeting was held in Pasadena on December 4, 1997 which was attended by
Messrs. Esrey, Schell, Sutton, Dodd, Dayton, Betty and certain other officers
and employees of the Company at which the possible components of a strategic
relationship were discussed. These discussions focused on strategic and
operational matters, including co-branding the Internet access service,
accessing Sprint's marketing and distribution channels, the nature of any
minority investment capital Sprint might make available to the Company and the
mechanism by which Sprint might acquire the equity securities of the Company not
already owned by Sprint and its affiliates at some point in the future.
 
    Further meetings were held in Pasadena on December 11 and 12, 1997 among
Messrs. Sutton, Betty and Dayton, internal Sprint counsel, outside counsel to
the Company, and the financial advisers of Sprint and the Company. These
discussions focused on the valuation of Sprint's in-kind contributions,
including Sprint Internet Passport subscribers, the Sprint brand, access to the
Sprint network and access to the Sprint marketing channels. The discussions also
focused on the terms and structure for a minority investment by Sprint in the
Company, the terms of any credit arrangements Sprint might provide, governance
rights, and
 
                                       32
<PAGE>
the timing and possible approaches under which Sprint would be permitted in the
future to seek to acquire the remaining equity securities of the Company.
 
    Further meetings were held in Pasadena on December 19 and 20, 1997 to
discuss a proposed preliminary term sheet prepared by Sprint. The term sheet
contemplated that Sprint would acquire a minority interest in the Company
through a cash tender offer. It also contemplated that in exchange for the
contribution of the Sprint Internet Passport subscribers and favorable terms for
access to the Sprint L.P. network, Sprint L.P. would receive a newly created
series of convertible preferred stock from the Company. The parties also
discussed a marketing agreement whereby the parties would jointly brand their
Internet products and Sprint would make its marketing channels available to the
Company with certain exclusivity and sales commitments.
 
    Also covered in the negotiations were terms of a standstill arrangement
which would preclude further acquisitions of the Company's equity securities by
Sprint, except in limited situations designed to ensure the receipt of fair
value by all stockholders in the event Sprint acquired additional equity
securities above agreed upon thresholds. The parties also discussed convertible
debt financing of up to $100,000,000. There were also discussions of limited
governance rights, stock registration rights, limitations on the Company
soliciting acquisition proposals (subject to the Board's fiduciary obligations)
and other customary rights of a financial investor. Throughout these and
subsequent meetings, considerable negotiations took place regarding all
strategic, operational, financial and governance aspects of the proposed
transactions.
 
    These proposals, counter proposals and revisions were reflected in numerous
further discussion drafts of possible terms which were circulated among Sprint
and the Company and their respective financial and legal advisers. Conference
and telephone calls were held in the latter part of December 1997 and in early
January 1998 among various members of management and the financial and legal
advisers to Sprint and the Company to discuss and refine these proposals.
Various members of management and employees of Sprint and the Company visited
Sprint's facilities in Reston, Virginia on December 30, 1997 in an attempt to
reach a common view on applicable network economics, network technologies and
engineering set ups.
 
    Meetings among various members of management and the financial and legal
advisers to Sprint and the Company were held during the evening of January 12,
1998 in Kansas City and during the following day to continue negotiation of the
terms of the transactions. Based on these negotiations, the parties agreed to
proceed immediately with the preparation of drafts of definitive agreements to
cover the matters encompassed by the Investment Agreement and Ancillary
Agreements. Numerous conference calls took place after January 12, 1998 to
divide drafting responsibilities, establish schedules and address issues arising
as part of the documentation effort. Prior to January 27, 1998, initial drafts
of most of the documents (and comments on most initial drafts) were exchanged.
 
    Negotiating sessions were held in Kansas City from January 27 through
February 1, 1998. Negotiations continued thereafter via numerous conference
calls and exchanges of drafts and comments through February 10, 1998, in an
effort to reach agreement on the matters encompassed by the Investment Agreement
and the Ancillary Agreements. Some of the negotiations between legal counsel for
Sprint and the Company occurred in person between February 6 and February 10,
1998.
 
    An overview of the possible transaction with the Company and related issues
were discussed at Sprint's Board of Directors meeting on December 9, 1997. A
meeting of Sprint's Board of Directors was held on February 10, 1998 and the
execution, delivery and performance of the Investment Agreement, the Ancillary
Agreements and the transactions contemplated thereby were approved.
 
    An overview of the possible transaction and related issues were discussed at
the Company's Board of Directors meeting on January 11, 1998. At a special
meeting held on January 20, 1998, senior management provided the Board with a
report on the status of the negotiations with Sprint and developments with
respect to other potential strategic alternatives. Draft agreements were first
presented to the Company's Board of Directors at a regular meeting held on
February 2, 1998. A special meeting of the Company's
 
                                       33
<PAGE>
Board of Directors was held on February 10, 1998 and the execution, delivery and
performance of the Investment Agreement, the Ancillary Agreements and the
transactions contemplated thereby were approved.
 
    Following approval by the Board of Directors of Sprint and the Company, the
Investment Agreement and the Ancillary Agreements were executed and delivered
after the close of financial markets in the United States on February 10, 1998.
The Offer and the other transactions contemplated by these agreements were
publicly announced before the financial markets in the United States opened on
February 11, 1998. The Offer was announced by Sprint in a summary advertisement
in the national edition of the Wall Street Journal on February 18, 1998, and
Sprint's Offer to Purchase, Letter of Transmittal (and related documents) and a
letter from Mr. Betty were mailed to all stockholders of the Company Common
Stock and made available to beneficial owners of the shares.
 
REASONS FOR THE RECOMMENDATION
 
    At a meeting held on February 10, 1998, the Board of Directors of the
Company, by unanimous vote of all Directors, (a) approved the transactions
contemplated by the Investment Agreement, (b) determined that such transactions
are fair to, and in the best interests of, the stockholders of the Company, and
(c) resolved to recommend that stockholders approve the transactions
contemplated by the Investment Agreement, including without limitation the
Company Stockholder Vote Matters. In arriving at its decision to approve such
transactions contemplated by the Investment Agreement and to recommend approval
of the Company Stockholder Vote Matters, the Board of Directors gave careful
consideration to the following factors:
 
        (i) The opportunity for each stockholder of the Company to receive cash
    for approximately 11% of the total number of shares of Common Stock held by
    each such stockholder pursuant to the Offer;
 
        (ii) The fact that the $45 per share price of the Offer represented a
    premium of approximately 32.4% over the last reported sales price of $34.00
    per share on February 9, 1998 (the last full trading date prior to the date
    of the Board's approval of the Offer) and a premium of approximately 53.7%
    over the average of the last reported sales prices for the 30 trading days
    preceding February 10, 1998 (as reported, in each case, on the Nasdaq
    National Market);
 
       (iii) The Board's thorough evaluation of a variety of other potential
    strategic alternatives and its analysis of the viability of and risks
    associated with such alternatives. In particular, the Board placed great
    value on the overall strategic importance of a potential relationship with
    Sprint, including (A) the value of creating an EarthLink-Sprint brand for
    Internet access and related services, (B) the potential commercial impact of
    having access to Sprint's nationwide marketing channels, with a commitment
    from Sprint to deliver not less than 150,000 net subscribers per year, (C)
    the addition to the Company's business of approximately 130,000 subscribers
    from Sprint L.P. immediately upon consummation of the transactions
    contemplated by the Investment Agreement, which would result in the Company
    having more than 600,000 subscribers in the aggregate at Closing, (D)
    favorable terms for access to Sprint's network pursuant to a network
    agreement, which diversifies the Company's operational risk by giving it
    another credible provider of Internet backbone services, and (E) the
    availability of additional capital through $100 million of Convertible Debt
    Financing from Sprint and Sprint L.P.'s purchase of Convertible Preferred
    Stock in exchange for $23.75 million in cash (in addition to the
    contribution by Sprint of SIP Subscribers and access to its network on
    favorable terms);
 
        (iv) The terms of the Governance Agreement, which allow Newco to remain
    an independent public company and which provide Newco and its stockholders
    with the ability to realize a control premium in a subsequent business
    combination transaction with Sprint or a third party, including (A) the
    right of Sprint to make a Sprint Offer at the "Fair Private Market Value" of
    Newco (a term
 
                                       34
<PAGE>
    that, by definition, contemplates an appropriate control premium in the
    contest of a competitive environment for that premium) and (B) Newco's right
    to receive and, in certain instances, pursue and solicit, third-party offers
    to effect business combinations;
 
        (v) The competitive environment in the Internet industry and the
    perceived beneficial effect of the strategic alliance on the Company's
    relationships with its employees and customers;
 
        (vi) The probability that the Offer and the other transactions
    contemplated by the Investment Agreement will be consummated, given the
    achievable nature of the conditions to consummation of the Offer; and
 
       (vii) The opinion of DMG that the Offer, the sale of the Convertible
    Preferred Stock and the Merger, when taken together, are fair, from a
    financial point of view, to the holders of Common Stock. The opinion of DMG
    contains a description of the factors considered, the assumptions made and
    the scope of review undertaken by DMG in rendering its opinion. A MORE
    DETAILED DESCRIPTION OF THE FAIRNESS OPINION IS PROVIDED BELOW UNDER THE
    CAPTION "OPINION OF FINANCIAL ADVISOR" AND THE FULL TEXT OF THE FAIRNESS
    OPINION RECEIVED BY THE BOARD OF DIRECTORS FROM DMG IS INCLUDED AS APPENDIX
    E HERETO.
 
        In light of all of the factors set forth above, the Board of Directors
    unanimously approved the transactions contemplated by the Investment
    Agreement. 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 the specific factors considered in reaching its
    decision, although the overall strategic value of the relationship with
    Sprint, as reflected in paragraph (iii) above, were of paramount importance
    to the Board's decision. In evaluating the Offer and the other transactions
    contemplated by the Investment Agreement, the Board concluded that the
    Company's prospects for growth would be substantially improved by entering
    into this strategic relationship with Sprint, while the Company could, at
    the same time, significantly reduce its operational risk.
 
OPINION OF FINANCIAL ADVISOR
 
    The Company retained DMG to render financial advisory services in connection
with potential equity investments by and commercial arrangements with other
entities. Pursuant to such engagement, DMG provided to the Company's Board of
Directors an opinion (the "Fairness Opinion") with respect to the fairness to
the Company's stockholders of the Offer, the sale of the Convertible Preferred
Stock and the Merger (the "Opinion Transactions"). DMG has delivered the
Fairness Opinion to the Company's Board, which states that based upon and
subject to the various considerations set forth therein, as of February 10,
1998, the Opinion Transactions were fair to the holders of Common Stock from a
financial point of view.
 
    THE FULL TEXT OF THE FAIRNESS OPINION, WHICH SETS FORTH, AMONG OTHER THINGS,
ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED, AND LIMITATIONS ON
THE SCOPE OF THE REVIEW UNDERTAKEN BY FAIRNESS IN RENDERING THE FAIRNESS
OPINION, IS ATTACHED AS APPENDIX E TO THIS PROXY STATEMENT/PROSPECTUS. THE
COMPANY'S STOCKHOLDERS ARE URGED TO READ THE FAIRNESS OPINION CAREFULLY AND IN
ITS ENTIRETY. THE FAIRNESS OPINION ADDRESSES ONLY THE FAIRNESS OF THE OPINION
TRANSACTIONS FROM A FINANCIAL POINT OF VIEW TO THE HOLDERS OF COMMON STOCK AS OF
THE DATE OF THE FAIRNESS OPINION, AND DOES NOT CONSTITUTE A RECOMMENDATION TO
ANY STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE SPECIAL MEETING.
THE SUMMARY OF THE FAIRNESS OPINION SET FORTH IN THIS PROXY STATEMENT/PROSPECTUS
IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE FAIRNESS
OPINION.
 
    In arriving at the Fairness Opinion, DMG did not ascribe a specific range of
fair value with respect to the Company's Common Stock, but made its
determination as to the fairness of the consideration based on the financial and
comparative analysis described below. The Fairness Opinion does not constitute a
recommendation of opinion to any stockholders as to whether or not to tender
shares of Common Stock pursuant to the Offer or as to how to vote at the Special
Meeting. In addition, DMG was not asked to
 
                                       35
<PAGE>
opine as to, and its opinion does not address, the underlying business decision
of the Company's Board to proceed with or to consummate the Merger.
 
    In connection with rendering the Fairness Opinion, DMG, among other things:
 
        (i) analyzed certain publicly available financial statements and other
    information concerning Sprint and the Company, respectively;
 
        (ii) analyzed certain internal financial statements and other financial
    and operating data concerning the Company prepared by the management of the
    Company;
 
       (iii) analyzed certain financial projections relating to the Company
    prepared by the management of the Company;
 
        (iv) discussed the past and current operations and financial condition
    and the prospects of the Company with senior executives of the Company;
 
        (v) discussed the financial value of the Convertible Preferred Stock
    Consideration with the management of the Company and the nature of the
    Convertible Preferred Stock Consideration with the management of Sprint;
 
        (vi) analyzed the pro forma impact of the Opinion Transactions on the
    revenue, operating cash flow, consolidated capitalization and other
    financial ratios of the Company;
 
       (vii) reviewed the reported prices and trading activity for the Common
    Stock;
 
      (viii) compared the financial performance of the Common Stock and the
    prices and trading activity of the Common Stock with that of certain other
    comparable publicly-traded companies and their securities;
 
        (ix) compared the results of operations of the Company with that of
    certain companies which DMG deemed to be reasonably similar to the Company;
 
        (x) reviewed the financial terms, to the extent publicly available, of
    certain comparable transactions;
 
        (xi) discussed, with the management of the Company, the strategic
    rationale and certain other benefits to the Company of the Opinion
    Transactions;
 
       (xii) participated in discussions and negotiations among representatives
    of the Company and Sprint and their financial and legal advisors;
 
      (xiii) reviewed the Investment Agreement and the Ancillary Agreements; and
 
       (xiv) performed such other analyses as DMG deemed appropriate.
 
    In rendering the Fairness Opinion, DMG assumed and relied on, without
independent verification, the accuracy and completeness of all the information
reviewed by DMG for purposes of the Fairness Opinion. DMG has also relied upon,
without independent verification, the assessment by the Company's management of
the strategic and other benefits expected to be derived from the Opinion
Transactions. DMG did not make any independent valuation or appraisal of the
assets, liabilities or technology of the Company, or of the Contribution Assets,
nor was DMG furnished with any such appraisals. DMG's opinion is necessarily
based on the economic, market and other conditions as in effect on, and the
information made available to DMG as of, the date hereof. DMG took into account
that because the Tendering Stockholders, who collectively own more than
1,250,000 shares of the outstanding Common Stock, agreed to facilitate the
transaction by tendering their shares to Sprint in connection with the Offer,
the Offer will be consummated regardless of whether any other stockholders of
the Company elect to tender their shares into the Offer.
 
                                       36

    The following is a summary of the material factors considered and the
principal financial analyses performed by DMG to arrive at the Fairness Opinion
delivered to the Company's Board in connection with its consideration of the
various transactions contemplated by the Investment Agreement. In arriving at
the Fairness Opinion, DMG did not quantify or attempt to assign relative weights
to the specific factors considered and financial analyses performed.
 
    The following is a summary of the analysis performed by DMG that was
reviewed with the Board of Directors of the Company at a meeting held on
February 2, 1998.
 
    COMPARATIVE STOCK PRICE PERFORMANCE:  As part of its analysis, DMG reviewed
the recent stock price performance of the Company and compared such performance
with that of America Online, Inc. ("AOL"), Mindspring Enterprises, Inc.
("Mindspring") and an index consisting of Cnet, Inc., Excite, Inc. and Yahoo!
Inc. (the "Index"). DMG observed that during the period from January 22, 1997
(the "IPO Date") to January 30, 1998, the stock price of the Company increased
139.4%, compared with an increase of 378.6% for Mindspring, 139.8% for AOL and
125.7% for the Index. DMG observed that during the period from December 1, 1997
to January 30, 1998, the market price of the the Company increased 59.1%,
compared with increases of 38.7%, 24.2% and 10.3% for the Index, AOL and
Mindspring, respectively. However, the companies constituting the Index do not
provide the same services as the Company, and therefore may not provide an
accurate comparative model of stock price performance.
 
    HISTORICAL VALUATION PER SUBSCRIBER:  DMG reviewed the ratio (computed on
the last trading day of each month) of EarthLink's aggregate value (equity value
plus debt less cash) to its number of subscribers (the "Subscriber Multiple") on
a monthly basis from January 1997 through January 1998. DMG observed that the
Company's Subscriber Multiple varied from $671 in January 1997 to a low of $247
in April 1997 to a high of $856 in January 1998. DMG also observed that the
average Subscriber Multiple for the Company since the IPO date was $508,
implying a valuation of $18.24 per share. DMG observed that the $45 per share
price of the Offer (the "Tender Price") implied a Subscriber Multiple of $1,447,
implying a premium of 184.8% to the average Subscriber Multiple since the IPO
Date and a premium of 69.0% to the Subscriber Multiple on January 30, 1998.
 
    PREMIUM ANALYSIS:  DMG observed that the Tender Price represented a premium
of 44.6% to the closing price of the Company's common stock on January 30, 1998.
DMG also observed that the Tender Price represented a premium of 62.9%, 92.8%,
107.8% and 160.8%, respectively, to the average closing stock price for the
Company in the 30, 60, 90 and 180 consecutive trading day periods ending on
January 30, 1998.
 
    SELECTED PRECEDENT TRANSACTIONS:  DMG reviewed the publicly available
financial terms of 38 precedent transactions involving the acquisition by one
party (the "acquiror") of between 5% and 40% of the equity of the target company
for more than $50 million in consideration. Based on the cash component of the
consideration in each of such precedent transactions, DMG observed average
premia of approximately 17.6%, 20.2% and 22.6% over the average of the closing
share prices of the target companies involved in such transactions over the one
day, one week and four week periods ending the day preceding the public
announcement of these transactions, respectively. DMG also observed that the
Tender Price represented average premia of approximately 44.6%, 36.4% and 57.5%
over the average the Company's share prices of the respective comparable periods
ending January 30, 1998.
 
    ILLUSTRATIVE FUTURE FINANCIAL PERFORMANCE:  DMG analyzed the implied range
of EBITDA, net income and total subscribers required in the year 2002 to support
the then current Company share price assuming a 25% to 30% return to investors
and assuming a range of EBITDA multiples, earnings multiples, and subscriber
multiples of 10.0x to 14.0x, 20.0x to 30.0x and $450 to $650, respectively. DMG
observed the required range of EBITDA, net income and total subscribers in the
year 2002 to be $143 million to $243 million, $66 million to $125 million and
3.1 million to 5.4 million subscribers, respectively.
 
                                       37
<PAGE>
    TERMINAL VALUE ANALYSIS:  DMG calculated the present value of the Company's
future share price based on multiples of EBITDA and subscribers, in each case in
year 2002. DMG used a range of EBITDA multiples of 10.0x to 14.0x, Subscriber
Multiples of $450 to $650 and discount rates of 25% to 30%. DMG observed that
the present value of the Company's future share price ranged from $14.28 to
$26.73, $14.88 to $33.59 and $20.44 to $61.45 based on three estimates using
differing variables.
 
    In connection with the review of the Transactions by the Company's Board of
Directors, DMG performed a variety of financial and comparative analyses for
purposes of the Fairness Opinion. While the foregoing summary describes all
material analyses and factors reviewed by DMG with the Company's Board of
Directors, it does not purport to be a complete description of the presentations
by DMG to the Board of Directors or the analyses performed by DMG in arriving at
the Fairness Opinion. The preparation of a fairness opinion is a complex process
and is not necessarily susceptible to partial analysis or summary description.
DMG 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 Fairness Opinion. In addition, DMG 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. In performing
its analyses, DMG made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters. Any
estimates contained therein are not necessarily indicative of future results or
actual values, which may be significantly more or less favorable than those
suggested by such estimates. Furthermore, the analyses performed by DMG are not
necessarily indicative of actual values or actual future results, which may be
significantly more or less favorable than suggested by such 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 DMG's analysis of the fairness of the Transactions, from a financial point of
view, to the holders of Common Stock and were provided to the Company's Board of
Directors in connection with the delivery of the Fairness Opinion.
 
    In the course of DMG's assignment, DMG had discussions (and was aware that
management of the Company had discussions) with several parties concerning a
possible transaction, business combination, or strategic alliance including all
or any part of the Company.
 
    In the ordinary course of its business, DMG may actively trade the
securities and loans of both the Company and Sprint for its own account and for
the accounts of its customers and, accordingly, may at any time hold a long or
short position in such securities and loans.
 
    The Company has agreed to pay DMG a fee for its financial advisory services
in connection with the Merger, including, among other things, rendering the
Fairness Opinion and making the presentation referred to above. Pursuant to a
letter agreement between the Company and DMG dated December 27, 1997, the
Company has agreed to pay DMG a transaction fee of approximately $7.4 million in
the event that the Opinion Transactions are consummated. In addition, the
Company has agreed to reimburse DMG for its reasonable out-of-pocket expenses
incurred in connection with its engagement, and to indemnify DMG and certain
related persons against certain liabilities and expenses arising out of or in
conjunction with its rendering of services under its engagement, including
certain liabilities under the federal securities laws.

ARE INCORPORATED HEREIN BY REFERENCE. ALL STOCKHOLDERS ARE URGED TO READ THE
APPENDICES IN THEIR ENTIRETY.
 
    THE BOARD OF DIRECTORS OF THE COMPANY RECOMMENDS THAT STOCKHOLDERS VOTE FOR
APPROVAL OF EACH OF THE COMPANY STOCKHOLDER VOTE MATTERS.
 
PROPOSAL NO. 1--APPROVAL OF THE MERGER
 
PROPOSAL
 
    The Board of Directors requests the stockholders' approval of the Merger,
the Merger Agreement and all transactions contemplated in the Merger Agreement.
The Merger Agreement is attached hereto as Appendix B and is incorporated by
reference herein.
 
GENERAL
 
    Pursuant to the Merger Agreement, as soon as practicable following
stockholder approval of the Company Stockholder Vote Matters at the Special
Meeting, the Company, Newco and Newco Sub will effect the Merger whereby Newco
Sub, a wholly-owned subsidiary of Newco, will merge with and into the Company,
with the Company as the surviving entity. All of the then issued and outstanding
Shares of Common Stock will be converted into an equal number of shares of Newco
Common Stock in the Merger. Upon consummation of Merger, the Company will be a
subsidiary of Newco.
 
    Pursuant to the proposed Merger, upon the Effective Time of the Merger, the
separate existence of Newco Sub shall cease and the Company (i) shall continue
to possess all of its assets, rights, powers and property as constituted
immediately prior to the Effective Time of the Merger, (ii) shall be subject to
all actions previously taken by its and Newco Sub's Board of Directors, (iii)
shall succeed, without other transfer, to all of the assets, rights, powers and
property of Newco Sub in the manner more fully set forth in Section 259 of the
DGCL; (iv) shall continue to be subject to all of the debts, liabilities and
obligations of Newco Sub in the same manner as if the Company had itself
incurred them, all as more fully provided under the applicable provisions of the
DGCL.
 
VOTE REQUIRED
 
    Approval of the Merger requires the affirmative vote of a majority of the
shares of Common Stock outstanding on the Record Date. Such shares may be voted
in person or be represented by proxy. Abstentions will have the effect of a vote
against the proposal. Pursuant to Section 251 of the DGCL and Rule 4460 of the
Marketplace Rules of The Nasdaq Stock Market, the Company is required to get
approval of its stockholders prior to the issuance of the Newco Common Stock in
exchange for the Common Stock in connection with the Merger.
 
    While the Merger is subject to the approval of the stockholders of the
Company, the votes to be cast pursuant to the Agreement to Vote and Tender Stock
and the Agreement to Vote Stock will ensure approval of the Merger. The Merger
will create a holding company structure which may provide certain advantages if
the scope of the Company's business expands in the future as well as
facilitating the economic efficiency of the strategic relationship with Sprint.
 
EFFECTIVE TIME OF THE MERGER
 
    Subject to the conditions to the obligations of the parties to effect the
Merger being satisfied or waived, the Effective Time will occur on the date and
at the time that the Certificate of Merger relating to the Merger becomes
effective under the DGCL with the Delaware Secretary of State. Unless otherwise
 
                                       39
<PAGE>
agreed upon by the parties to the Merger Agreement, the Effective Time is
expected to occur as soon as practicable after approval of the Merger by the
respective stockholders of the Company, Newco and Newco Sub and the effective
date (including expiration of all applicable waiting periods) of all required
consents of any regulatory authority having jurisdiction over the Merger.
 
    While the Agreement to Vote and Tender Stock and Agreement to Vote Stock
will ensure stockholder approval of the Merger, no assurance can be provided
that other conditions precedent to the Merger can or will be satisfied See
"--Conditions." The Company, Newco and Newco Sub anticipate that all conditions
to consummation of the Merger will be satisfied so that the Merger can be
consummated during the second quarter of 1998. Delays in the consummation of the
Merger could occur, however.
 
MERGER CONSIDERATION
 
    Pursuant to the Merger Agreement, as a result of the Merger each share of
Common Stock issued and outstanding immediately prior thereto shall, by virtue
of the Merger and without any action by any person, be converted into and
exchanged for one fully-paid and nonassessable share of Newco Common Stock.
 
CERTIFICATE OF INCORPORATION AND BYLAWS
 
    Pursuant to the Merger, the Certificate of Incorporation and Bylaws of Newco
Sub will become the Certificate of Incorporation and Bylaws of the surviving
corporation, and the Certificate of Incorporation and Bylaws of Newco will take
effect as the constitutive documents of the corporation whose stock is
registered pursuant to the Exchange Act. The Certificate of Incorporation and
Bylaws of Newco are substantially similar to the Certificate of Incorporation
and Bylaws of the Company, except that (a) the number of authorized shares of
Preferred Stock was increased from 10 million to 25 million, (b) the scope of
indemnification of officers and directors was increased to the maximum extent
allowed by the DGCL, and (c) the cumulative voting provision was deleted. The
deleted cumulative voting provision had allowed each stockholder to aggregate
its available votes for all open board positions and distribute the total number
of votes for one or more director nominees.
 
DIRECTORS AND OFFICERS
 
    The directors and officers of the Company will become the directors and
officers of Newco until their successors have been duly elected or appointed and
qualified or until their earlier death, resignation or removal in accordance
with Newco's Certificate of Incorporation and Bylaws, except that the two
directors elected by the holders of the Convertible Preferred Stock of Newco
will be elected immediately following the Closing. Sprint's initial designees
are: (a) Willliam T. Esrey, Chairman and Chief Executive Officer of Sprint, and
(b) Patti S. Manuel, President and Chief Operating Officer--Long-Distance
Division of Sprint. See "Other Information about EarthLink--Board of Directors;
Sprint Designees."
 
DISSENTERS' RIGHTS OF APPRAISAL
 
    Because the Common Stock was included on the Nasdaq National Market on the
Record Date and because the Common Stock will be converted in the Merger solely
into the right to receive Newco Common Stock, which will be included on the
Nasdaq National Market at the Effective Time, the holders of Common Stock will
not have dissenters' rights of appraisal with respect to the Merger pursuant to
Section 262 of the DGCL. However, EarthLink, which was originally incorporated
as a California corporation (prior to being reincorporated as a Delaware
corporation in 1996), may be considered a "quasi-California corporation"
pursuant to Section 2115 of the CGCL. If so, the Company's stockholders who have
not approved the Merger may be entitled to dissenters' rights under Chapter 13
of the CGCL in connection with the Merger if demands for such rights are made
with respect to (i) five percent or more of the outstanding shares of Common
Stock or (ii) "restricted shares" of Common Stock (i.e., those shares
 
                                       40
<PAGE>
with respect to which there exists any restriction or transfer imposed by the
Company or any law or regulation).
 
    THE FOLLOWING SUMMARY OF DISSENTERS' RIGHTS UNDER CALIFORNIA LAW IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO CHAPTER 13 OF THE CALIFORNIA GENERAL
CORPORATION LAW, THE COMPLETE TEXT OF WHICH IS ATTACHED HERETO AS APPENDIX G --
CHAPTER 13 OF THE GENERAL CORPORATION LAW OF THE STATE OF CALIFORNIA. FAILURE TO
STRICTLY FOLLOW THE PROCEDURES SET FORTH IN CHAPTER 13 OF THE CALIFORNIA GENERAL
CORPORATION LAW MAY RESULT IN THE LOSS, TERMINATION OR WAIVER OF DISSENTERS'
RIGHTS. A STOCKHOLDER OF THE COMPANY WHO VOTES IN FAVOR OF PROPOSAL NO. 1 WILL
NOT BE ABLE TO EXERCISE DISSENTERS' RIGHTS, AS DESCRIBED HEREIN.
 
    Because the Common Stock is traded on the Nasdaq National Market,
dissenters' rights will be available to stockholders of the Company under the
CGCL only if the holders of five percent or more of the Common Stock or holders
of restricted shares make a written demand upon the Company for the purchase of
dissenting shares in accordance with Chapter 13 of the CGCL. If either of these
conditions is satisfied and the Merger is consummated, stockholders of the
Company who dissent from the Merger by complying with the procedures set forth
in Chapter 13 would be entitled to receive an amount equal to the fair market
value of their shares as of February 10, 1998, the day before the public
announcement of the Merger. The closing sales price on February 10, 1998 was
$38.625. A copy of Chapter 13 of the CGCL is attached hereto as Appendix G and
should be read for more complete information concerning dissenters' rights. THE
REQUIRED PROCEDURE SET FORTH IN CHAPTER 13 OF THE CGCL MUST BE FOLLOWED EXACTLY
OR ANY DISSENTERS' RIGHTS MAY BE LOST. The information set forth below is a
general summary of dissenters' rights as they apply to the Company's
stockholders and is qualified in its entirety by reference to Appendix G.
 
    In order to be entitled to exercise dissenters' rights, a shareholder of the
Company must vote "AGAINST" the Merger. Thus, any stockholder who wishes to
dissent and executes and returns a proxy in the accompanying form must specify
that his or her shares are to be voted "AGAINST" Proposal No. 1. If the
stockholder returns a proxy without voting instructions or with instructions to
vote "FOR" Proposal No. 1, his or her shares will automatically be voted in
favor of the Merger and the stockholder will lose any dissenters' rights. In
addition, if the stockholder abstains from voting his or her shares, the
stockholder will lose his or her dissenters' rights. Only a holder of record of
shares of the Common Stock on the Record Date (or his or her duly appointed
representative) is entitled to assert a purchase demand for the shares
registered in that holder's name.
 
    Furthermore, in order to preserve his or her dissenters' rights, a
stockholder must make a written demand upon the Company for the purchase of
dissenting shares and payment to such stockholder of their fair market value,
specifying the number of shares held of record by such stockholder and a
statement of what the stockholder claims to be the fair market value of those
shares as of February 10, 1998. Such demand must be addressed to: Kirsten L.
Hansen, Secretary, 3100 New York Drive, Pasadena, CA 91107, and must be received
by the Company not later than the date of the Special Meeting. A vote "AGAINST"
the Merger does not constitute such written demand.
 
    If the holders of five percent or more of the outstanding shares of the
Common Stock have submitted a written demand for the Company to purchase their
shares or if such a demand is submitted by holders of restricted shares, and
these demands are received by the Company on or before the date of the Special
Meeting and the Merger is approved, the Company will have 10 days after such
approval to send to those stockholders who have voted against the approval of
the Merger written notice of such approval accompanied by a copy of Chapter 13
of the CGCL, a statement of the price determined by the Company to represent the
fair market value of the dissenting shares as of February 10, 1998, and a brief
description of the procedures to be followed if a stockholder desires to
exercise dissenters' rights. Within 30 days after
 
                                       41
<PAGE>
the date on which the notice of the approval of the Merger is mailed, the
dissenting stockholder must surrender to the Company, at the office designated
in the notice of approval, the certificate representing the dissenting shares to
be stamped or endorsed with a statement that they are dissenting shares or to be
exchanged for certificates of appropriate denomination to stamped or endorsed.
Any shares of the Company's Common Stock that are transferred prior to their
submission for endorsement lose their status as dissenting shares.
 
    If the Company and the dissenting stockholder agree that the surrendered
shares are dissenting shares and agree upon the price of the shares, the
dissenting stockholder will be entitled to the agreed price with interest
thereon at the legal rate on judgments from the date of the agreement. Payment
of the fair market value of the dissenting shares shall be made within 30 days
after the amount thereof has been agreed upon or 30 days after any statutory or
contractual conditions to the Merger have been satisfied, whichever is later,
subject to the surrender of the certificates therefor, unless provided otherwise
by agreement.
 
    If the Company denies that the shares surrendered are dissenting shares, or
the Company and the dissenting stockholder fail to agree on a fair market value
of such shares, then the dissenting stockholder of the Company must, within six
months after the notice of approval is mailed, file a complain at the Superior
Court of the proper county of the State of California requesting the court to
make such determinations or intervene in pending action brought by any other
dissenting stockholder. If the complaint is not filed or intervention in a
pending action is not made within the specified six-month period, the
dissenters' rights are lost. If the fair market value of the dissenting shares
is at issue, the court will determine, or will appoint one or more impartial
appraisers to determine, such fair market value. A dissenting stockholder may
not withdraw his or her dissent or demand for payment unless the Company
consents to such withdrawal. Notwithstanding the offer of dissenters' rights
pursuant to the CGCL as described herein, the Company does not necessarily
acknowledge or agree that it is a "quasi-California corporation" or otherwise
legally subject to the CGCL, and the offer of such rights as described herein
shall not be deemed to be such an admission.

REGULATORY APPROVALS
 
    Certain transactions contemplated in the Investment Agreement are subject to
review and approval by the Federal Trade Commission and Department of Justice
under the HSR Act, as described in "Summary--the Offer." Such transactions may
not be consummated in the absence of receipt of such regulatory approval.
However, the applicable waiting period under the HSR Act has expired, such that
the transactions may now be consummated and the HSR Condition deemed satisfied.
 
    The Company is not aware of any other material governmental approvals or
actions that are required for consummation of the Merger, except as described
above. Should any other approval or action be required, it presently is
contemplated that such approval or action would be sought.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    GENERAL.  Certain members of the Company's management and of the Company's
Board of Directors have interests in the Merger that are in addition to any
interests they may have as stockholders of the
 
                                       43
<PAGE>
Company generally. These interests include, among other things, the presence of
expanded protections from liability for the Company's directors and officers in
Newco's Certificate of Incorporation, and director and officer insurance
coverage for the Company's directors and officers, and certain severance and
other employee benefits, as described below. As of the Record Date, directors
and executive officers of the Company own 4,643,427 shares of Common Stock for
which they will receive the same consideration as the other holders of Common
Stock.
 
    INSURANCE.  The Company expects that Newco will maintain director and
officer liability insurance of at least the same coverage and amounts as
provided by the Company's current director and officer liability insurance, with
respect to claims arising from events that occur prior to the Effective Time and
covering persons who currently are covered by such insurance.
 
    EXECUTIVE ARRANGEMENTS.  Charles G. Betty serves as President and Chief
Executive Officer of EarthLink under an Employment Agreement dated January 15,
1996 (as amended, the "Employment Agreement"). Mr. Betty's Employment Agreement
has a two-year term and provides for (i) a salary of $225,000 per year plus an
annual bonus of $75,000 upon attainment of certain performance goals, (ii) a
$24,000 per year travel allowance and (iii) severance compensation of 100% of
his then-current salary. Pursuant to the operation of the Merger Agreement, Mr.
Betty will be the President and Chief Executive Officer of Newco, with the
Employment Agreement continuing its effectiveness after the Merger. The
Employment Agreement provides, among other things, that all of Mr. Betty's
unvested options to buy Common Stock will immediately vest upon a "Change of
Control" (as defined therein) of the Company or a termination of employment
other than for "Cause" (as defined therein) or as a result of the Company's
breach of the Employment Agreement. Under the Employment Agreement, a "Change of
Control" generally is a sale of all or a material portion of the Company's
assets, a merger or recapitalization whereby the Company is not the surviving
entity, acquisition of beneficial ownership of 25% or more of the outstanding
voting stock of the Company by any person or entity, failure of the then-current
members of the Board of Directors to constitute a majority of the Board, and as
determined by the Board of Directors in its sole discretion. The Employment
Agreement was amended February 10, 1998 to exclude the transactions contemplated
by the Investment Agreement and the Ancillary Agreements from the definition of
"Change of Control" (including the issuance of the Convertible Preferred Stock,
the Convertible Notes and the Common Stock issuable upon conversion thereof),
subject to certain exceptions. The Board of Directors of the Company approved
such amendment on February 10, 1998.
 
    The Company anticipates that it will further amend Mr. Betty's Employment
Agreement to, among other things, (i) employ Mr. Betty as President and Chief
Executive Office of Newco, Inc. after consummation of the transactions
contemplated by the Investment Agreement, (ii) extend the term of the Employment
Agreement for three years from April 1, 1998 with automatic extensions from year
to year after 2001 and (iii) increase Mr. Betty's Base salary to $300,000 per
year. These anticipated amendments are pending review and approval by the
Compensation Committee of the Board of Directors.
 
    See also "Other Information about EarthLink--Beneficial Ownership of Common
Stock" for a description of the ownership of Common Stock by the Company's
directors, executive officers and certain other stockholders. See "Description
of Certain Ancillary Agreements--Agreement to Vote Stock; Agreement to Vote and
Tender Stock" and "--Stockholders' Agreement" for a description of certain
agreements to which certain members of the Company's Board of Directors and
executive officers are parties.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    It is intended that the Merger will be treated as a reorganization within
the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the
"Code"). If the Merger qualifies as a tax-free reorganization under such Code
section, (a) no gain or loss will be recognized by a holder of Common Stock upon
the exchange of such Common Stock solely for shares of Newco Common Stock, (b)
the basis of the shares of Newco Common Stock received by each holder of Company
Common Stock in the Merger
 
                                       44
<PAGE>
will be the same as the basis of the shares of Company Common Stock exchanged
therefor, (c) the holding period for the shares of Newco Common Stock received
by the EarthLink stockholders in the Merger will include the holding period
applicable to the shares of the EarthLink Common Stock exchanged therefor, if
such shares of Company Common Stock are held as a capital asset at the effective
time of the Merger, and (d) neither the Company, Newco nor Newco Sub will
recognize gain or loss on the Merger. Hunton & Williams, Atlanta, Georgia,
counsel to the Company, will provide an opinion regarding the above and other
related tax consequences, which opinions are subject to certain qualifications
and assumptions as set forth therein.
 
    THE FOREGOING SUMMARY OF CERTAIN ANTICIPATED FEDERAL INCOME TAX CONSEQUENCES
OF THE MERGER TO THE COMPANY'S STOCKHOLDERS DOES NOT PURPORT TO ADDRESS ALL
ASPECTS OF THE POSSIBLE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER AND IS NOT
INTENDED AS TAX ADVICE TO ANY PERSON. IN PARTICULAR, AND WITHOUT LIMITING THE
FOREGOING, THIS SUMMARY DOES NOT ADDRESS THE FEDERAL INCOME TAX CONSEQUENCES OF
THE MERGER TO THE COMPANY'S STOCKHOLDERS IN LIGHT OF THEIR PARTICULAR
CIRCUMSTANCES OR STATUS. NOR DOES THIS SUMMARY ADDRESS ANY CONSEQUENCES OF THE
MERGER UNDER ANY STATE, LOCAL, ESTATE, OR FOREIGN TAX LAWS. COMPANY
STOCKHOLDERS, THEREFORE, ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER.
 
ACCOUNTING TREATMENT
 
    There will be no new basis or step-up in basis in the assets of the Company
as a result of the Merger. The acquisition of the SIP Subscribers from Sprint is
considered an acquisition of a business and will be accounted for using the
purchase method.
 
EXPENSES AND FEES
 
    The Investment Agreement provides that all fees and expenses incurred in
connection with the Investment Agreement and the transactions contemplated
thereby (including without limitation the Company Stockholder Vote Matters) and
the Ancillary Agreements shall be paid by the party incurring such fees or
expenses, whether or not such transactions are consummated. Such expenses
include filing, registration and application fees, printing and distribution
fees, and fees and expenses of financial or other consultants, investment
bankers, accountants, and legal counsel. However, one-half of the reasonable
out-of-pocket expenses incurred by the Company in preparing this Proxy
Statement/Prospectus and the S-4 Registration Statement, printing and mailing
the Proxy Statement/Prospectus, the SEC filing fees for the S-4 Registration
Statement and in holding the Special Meeting of Company stockholders to approve
the Merger shall be paid by Sprint.
 
RESALES OF NEWCO COMMON STOCK
 
    Newco Common Stock to be issued to stockholders of the Company in connection
with the Merger will be registered under the Securities Act and included for
trading on the Nasdaq National Market. All shares of Newco Common Stock received
by holders of Common Stock and all shares of Newco Common Stock issued and
outstanding immediately prior to the Effective Time, will have been registered
under the Securities Act and will be freely transferable upon consummation of
the Merger by those stockholders of the Company not deemed to be "affiliates" of
the Company or Newco. "Affiliates" generally are defined as persons or entities
who control, are controlled by, or are under common control with the Company or
Newco at the time of the Special Meeting (generally, executive officers and
directors).
 
    Rule 145 promulgated under the Securities Act restricts the sale of Newco
Common Stock received in the Merger by Affiliates and certain of their family
members and related interests. Generally, during the
 
                                       45
<PAGE>
year following the Effective Time, Affiliates of the Company or Newco may resell
publicly the Newco Common Stock received by them in the Merger within certain
limitations as to the amount of Newco Common Stock sold in any three-month
period and as to the manner of sale. After the one-year period, such Affiliates
may resell their shares without restriction because affiliates of the Company
will become affiliates of Newco upon the Merger, the same restrictions will
generally apply to them under Rule 144. The ability of Affiliates to resell
shares of Newco Common Stock received in the Merger under Rule 144 or 145 as
summarized herein generally will be subject to satisfaction by the Company (and
Newco as the Company's successor registrant) of its Exchange Act reporting
requirements for specified periods prior to the time of sale. Affiliates will
receive additional information regarding the effect of Rules 144 and 145 on
their ability to resell Newco Common Stock received in the Merger. Affiliates
also would be permitted to resell Newco Common Stock received in the Merger
pursuant to an effective registration statement under the Securities Act or
another available exemption from the Securities Act registration requirements.
This Proxy Statement/Prospectus does not cover any resales of Newco Common Stock
received by persons who may be deemed to be Affiliates of the Company or Newco.
 
TERMINATION
 
    At any time prior to the Effective Date, the Merger Agreement may be
terminated and the Merger abandoned for any reason whatsoever by the Board of
Directors of any of the Company, Newco or Newco Sub, notwithstanding the
approval of the Merger by the stockholders of the Company at the Special Meeting
or by the sole stockholder of Newco or Newco Sub.
 
PROPOSAL NO. 2--APPROVAL FOR THE ISSUANCE OF CONVERTIBLE PREFERRED STOCK
 
PROPOSAL
 
    The Board of Directors requests the stockholders' approval of the proposed
issuance of the Convertible Preferred Stock and the Newco Common Stock into
which such securities are convertible, as described herein. The terms of the
Convertible Preferred Stock are set forth in the proposed form of the
Certificate of Designation, of such stock which is attached hereto as Appendix C
and incorporated by reference herein.
 
GENERAL
 
    In connection with the Investment Agreement as described above, the Company
proposes to issue to Sprint 4,102,941 shares of Convertible Preferred Stock.
 
THE CONVERTIBLE PREFERRED STOCK
 
    Pursuant to the terms of the Investment Agreement, the Company proposes to
issue 4,102,941 shares of Convertible Preferred Stock to Sprint in exchange for
the Convertible Preferred Stock Consideration. Such shares of Convertible
Preferred Stock are initially convertible into 3,533,411 Shares of Newco Common
Stock at the Closing. However, the Convertible Preferred Stock may not be
converted into Newco Common Stock for one year after the Merger, except such
limitation shall not apply in the event of a Business Combination (as defined
therein). Immediately after consummation of the Offer, the Merger and the other
transactions contemplated by the Investment Agreement, Sprint would own
approximately 26.6% of the total number of issued and outstanding shares of
Newco Common Stock on a fully diluted basis (that is, assuming that all
warrants, options and convertible notes representing rights to purchase Common
Stock or Newco Common Stock, including the Convertible Preferred Stock, are
exercised or converted into Newco Common Stock). However, the Convertible
Preferred Stock will pay dividends thereon for the first five years in the form
of increases in its Liquidation Value ("Liquidation Accretion Dividends"), at a
per annum rate of 3% of the Liquidation Value, which will accrue and compound
quarterly in arrears, but which will accelerate in the event of a business
combination or an optional
 
                                       46
<PAGE>
redemption of the Convertible Preferred Stock by Newco. At the Closing, the
Liquidation Value will be the average of the closing price per share of Newco
Common Stock for the 30 trading days prior to the Closing Date. Increases in the
Liquidation Value will have the effect of increasing the number of shares of
Newco Common stock that Sprint will receive upon conversion of the Convertible
Preferred Stock. Assuming that the Convertible Preferred Stock is held by Sprint
for the initial five year period following the Closing or that certain
Liquidation Accretion Dividends are accelerated upon the consummation of a
Business Combination or optional redemption, Sprint L.P. will be entitled to
receive 4,102,941 shares of Newco Common Stock upon conversion thereof. If the
fully diluted number of Shares, as calculated above, were the same at that time,
Sprint would then own approximately 28.8% of the total number of issued and
outstanding shares of Newco Common Stock on that basis. The Conversion Price is
also subject to customary anti-dilution adjustments.
 
    Cash dividends at such rate are payable after five years from the Closing
Date when declared by the Board of Directors of Newco out of funds legally
available therefor and such dividends accumulate if not declared and paid. After
the twentieth anniversary of the Closing Date, such cumulative cash dividends
accrue at the rate per annum of 8% of the Liquidation Value, which rate
increases annually by 200 basis points up to a maximum rate of 12% per annum.
Holders of Convertible Preferred Stock are entitled to a liquidation preference
upon any voluntary or involuntary liquidation, dissolution or winding up of
Newco (Liquidation Event) in an amount per share equal to the sum of (i) the
average closing price per share of Common Stock for the 30 trading days
preceding the Closing Date, (ii) the amount of all Liquidation Accretion
Dividends that have been paid (including an amount equal to a prorated dividend
for the period from the latest "Dividend Accrual Date" (as hereinafter defined)
through the date of the Liquidation Event), and (iii) all accumulations of
accrued by unpaid cash dividends (the sum of (i), (ii) and (iii) is referred to
as the Liquidation Value). Each share of Convertible Preferred Stock initially
converts into less than one share of Newco Common Stock, but increases to a
one-for-one conversion (subject, in each case, to customary antidilution
adjustments) over a five-year period (but may be accelerated upon a Business
Combination or optional redemption). Pursuant to the Governance Agreement and
the Certificate of Designation, after the Closing the holders of the Convertible
Preferred Stock are entitled to elect two directors to the Board of Directors of
the Company (the Investor Directors) and to certain committees of the Board of
Directors, which rights may be reduced to the election of one director or no
directors, based generally upon the percentage of the outstanding Common Stock
owned by Sprint and Sprint L.P. Also, pursuant to the Governance Agreement and
the Certificate of Designation, the approval of all the Investor Directors is
required for certain actions proposed by the Company. See "Description of The
Investment Agreement--The Investment Agreement--The Issuance of Convertible
Preferred Stock" and "Description of the Governance Agreement--Corporate
Governance."
 
    Similarly, the Convertible Preferred Stock has the right to prior approval,
by the vote of at least 66 2/3% of the then-outstanding Convertible Preferred
Stock voting as a class, of the following proposed actions by the Company: (a)
alteration of the rights, preferences and privileges of the Convertible
Preferred Stock that would adversely affect such class of stock, (b) increase in
the authorized number of shares of Convertible Preferred Stock, create any new
series of stock or other securities convertible into equity securities of the
Company having a preference over or being on parity with the Convertible
Preferred Stock with respect to voting, dividends, distribution of assets upon
liquidation or conversion rights, (c) amendment to the Company's Certificate of
Incorporation, Bylaws or other organizational documents or take any action or
enter into any other agreement which prohibit or materially conflict with the
Company's obligations under the Certificate of Designation, or (d) engage in any
event of liquidation, dissolution or bankruptcy. See the Certificate of
Designation attached hereto as Appendix C.
 
VOTE REQUIRED
 
    Approval of this proposal by the stockholders of the Company requires the
affirmative vote by the holders of a majority of the Shares present in person or
represented by proxy at the Special Meeting and
 
                                       47
<PAGE>
entitled to vote thereon. Shares represented by proxies that reflect abstentions
or "broker non-votes" (i.e., shares held by a broker or nominee which are
represented at the Special Meeting, but with respect to which such broker or
nominee is not empowered to vote on a particular proposal) will be counted as
Shares that are present and entitled to vote for purposes of determining the
presence of a quorum. Accordingly, with respect to the approval of this
proposal, abstentions and broker non-votes will be counted as part of the number
of votes to be used in determining if the proposal has received the requisite
number of votes for approval. Thus, an abstention and a broker non-vote will
have the same effect as a vote against the proposal. Pursuant to Rule 4460 of
the Marketplace Rules of The Nasdaq Stock Market applicable to Nasdaq National
Market-listed companies, the Company is required to obtain approval of its
stockholders prior to the issuance of the Convertible Preferred Stock.
 
PROPOSAL NO. 3--APPROVAL FOR THE ISSUANCE OF CONVERTIBLE NOTES
 
PROPOSAL
 
    The Board of Directors requests the stockholders' approval of the issuance
of the Convertible Notes and the Newco Common Stock into which such securities
are convertible.
 
CONVERTIBLE NOTES ISSUED PURSUANT TO THE CREDIT AGREEMENT
 
    Concurrently with the Merger, the Credit Agreement will become effective.
The Credit Agreement (which includes a form of Convertible Note as Exhibit A
thereto) is attached as Appendix D hereto and incorporated by reference herein.
Under the Investment Agreement and Credit Agreement, Sprint will initially make
available up to $25 million in debt financing. Each year after the Closing Date,
the aggregate amount that Sprint is obligated to advance is increased by $25
million to a maximum of $100 million on a cumulative basis. Advances of funds to
the Company under the Credit Agreement will be evidenced by Convertible Notes,
which are convertible into Newco Common Stock. Each Convertible Note will mature
five years from the dated issuance and will bear interest at a rate equal to 6%
per annum. The Company has no present intention to incur indebtedness under the
Credit Agreement.
 
    The Convertible Notes are convertible into shares of Newco Common Stock at a
conversion price of 130% of the average market price (i.e., the closing sale
price over a 30 trading day period) at the time a particular Convertible Note is
issued to evidence an advance under the Credit Agreement. The Conversion Price
is subject to customary anti-dilution adjustments.
 
    Because the number of shares of Newco Common Stock receivable upon
conversion of the Convertible Notes is dependent upon future trading prices for
Newco Common Stock, and because the amount of advances under the Credit
Agreement is within Newco's discretion (provided it is in compliance with
applicable Credit Agreement conditions), it is not possible to predict the
extent to which, if any, Sprint's fully diluted ownership would increase in the
event that advances are made under the Credit Agreement.
 
    Sprint's obligation to make advances under the Credit Agreement terminates
upon the earlier of (i) the fifth anniversary of the Closing Date, (ii)
acceleration of the indebtedness evidenced by the Convertible Notes upon an
Event of Default (as defined below), (iii) consummation of a Business
Combination, or (iv) termination of the Marketing Agreement pursuant to certain
provisions thereof. An Event of Default shall occur if (i) there is a breach or
there are breaches of any of the representations or warranties set forth in the
Credit Agreement unless such breach or breaches would not in the aggregate have
a Material Adverse Effect on Newco, the Company and their subsidiaries, taken as
a whole, (ii) nonpayment of principal or interest within fourteen (14) days
after the same becomes due, (iii) a breach of certain financial and other
covenants, and in certain cases, a failure to cure such breach within the
applicable cure period, (iv) a default by Newco or the Company in any agreement
or agreements under which indebtedness in excess of $5 million was created, or
the occurrence of any other event or existence of any condition, the effect of
any of which causes, or permits the holder of such indebtedness to cause, such
indebtedness to become due prior to its stated maturity, or any such
indebtedness shall be declared due
 
                                       48
<PAGE>
and payable prior to the stated maturity thereof, (v) Newco or the Company files
for relief under bankruptcy, receivership, or similar laws, or fails to contest
any involuntary petition in bankruptcy filed with regard to Newco or the
Company, (vi) any condemnation of a substantial portion of the property of Newco
or the Company, or (vii) Newco or the Company fails within thirty (30) days to
pay, bond or otherwise discharge any judgments or orders for the payment of
money in excess of $1 million; which are not stayed on appeal or otherwise
contested in good faith. "Material Adverse Effect" is defined to mean any change
or effect having a material adverse effect (or any development as to which there
is a substantial likelihood, insofar as can be foreseen, that would have such an
effect) on the business, properties, assets, condition (financial or otherwise),
or results of operations of the Company, Newco, Newco Sub, Sprint, Sprint L.P.
and Sprint's subsidiaries, as the case may be.
 
VOTE REQUIRED
 
    Approval of this proposal by the stockholders of the Company requires the
affirmative vote by holders of a majority of the Shares present in person or
represented by proxy at the Special Meeting and entitled to vote thereon. Shares
represented by proxies that reflect abstentions or "broker non-votes" (i.e.,
shares held by a broker or nominee which are represented at the Special Meeting,
but with respect to which such broker or nominee is not empowered to vote on a
particular proposal) will be counted as Shares that are present and entitled to
vote for purposes of determining the presence of a quorum. Accordingly, with
respect to the approval of this proposal, abstentions and broker non-votes will
be counted as part of the number of votes to be used in determining if the
proposal has received the requisite number of votes for approval. Thus, an
abstention and a broker non-vote will have the same effect as a vote against the
proposal. Pursuant to Rule 4460 of the Marketplace Rules of The Nasdaq Stock
Market applicable to Nasdaq National Market-listed companies, the Company is
required to obtain approval of its stockholders prior to the issuance of the
Convertible Notes.
 
PROPOSAL NO. 4--APPROVAL FOR THE ISSUANCE OF CERTAIN SECURITIES UPON EXERCISE OF
  OPTIONS AND WARRANTS
 
PROPOSAL
 
    The Board of Directors requests the stockholders' approval of the issuance
of Newco Common Stock upon the exercise of certain options and warrants to
purchase Common Stock of the Company, as described herein.
 
THE ISSUANCE OF NEWCO COMMON STOCK UPON EXERCISE OF CERTAIN OPTIONS AND WARRANTS
 
    Upon the Effective Time of the Merger, to the extent permitted by the terms
of such instruments as in effect at the Effective Time of the Merger, Newco
shall assume the obligations of the Company under any and all securities,
warrants, calls, rights to purchase, rights of first refusal, securities
convertible into or exchangeable for voting securities, commitments, agreements,
arrangements or undertakings of any kind to which the Company is a party or by
which it is bound obligating the Company to issue, deliver or sell or create, or
cause to be issued, delivered or sold or created, additional shares of the
capital stock of or other voting securities or phantom stock or other
contractual rights the value of which is determined in whole or in part by the
value of any capital stock of the Company, or obligating the Company to issue,
grant, extend or enter into any such security, option, warrant, call, right,
commitment, agreement, arrangement, or undertaking (collectively, the "Dilutable
Securities") on the same terms and conditions as were in effect immediately
prior to the Merger. After the Merger, each such Dilutable Security shall
become, subject to the provisions set forth below, an option, right to purchase
or a security convertible into Newco Common Stock on the basis of one share of
Newco Common Stock for each one share of the Company Common Stock issuable
pursuant to any such Dilutable Security, on the same terms and conditions and at
an exercise price equal to the exercise price applicable to any such Dilutable
Security at the Effective Time of the Merger.
 
                                       49
<PAGE>
    As of the Record Date, 2,552,679 shares of Common Stock were reserved for
issuance upon exercise of all such Dilutable Securities. A number of shares of
Newco Common Stock will be reserved for issuance upon the exercise of options,
stock purchase rights and convertible securities equal to the number of shares
of Company Common Stock so reserved immediately prior to the Effective Date of
the Merger.
 
    The assumed Rights shall not entitle any holder thereof to a fractional
share upon exercise or conversion (unless the holder was entitled to a
fractional interest immediately prior to the Merger). In lieu thereof, any
fractional share interests to which a holder of an assumed Right (other than an
option issued pursuant to the Company's 1995 Stock Option Plan, as amended)
would otherwise be entitled upon exercise or conversion shall be aggregated (but
only with other similar Rights which have the same per share terms). To the
extent that after such aggregation the holder would still be entitled to a
fractional share with respect thereto upon exercise or conversion, the holder
shall be entitled, upon the exercise or conversion of all such assumed Rights
pursuant to their terms (as modified herein), to one full share of common stock
in lieu of such fractional share. With respect to each class of such similar
Rights, no holder will be entitled to more than one full share in lieu of a
fractional share upon exercise or conversion.
 
VOTE REQUIRED
 
    Approval of this proposal by the stockholders of the Company requires the
affirmative vote by holders of a majority of the Shares present in person or
represented by proxy at the Special Meeting and entitled to vote thereon. Shares
represented by proxies that reflect abstentions or "broker non-votes" (i.e.,
shares held by a broker or nominee which are represented at the Special Meeting,
but with respect to which such broker or nominee is not empowered to vote on a
particular proposal) will be counted as Shares that are present and entitled to
vote for purposes of determining the presence of a quorum. Accordingly, with
respect to the approval of this proposal, abstentions and broker non-votes will
be counted as part of the number of votes to be used in determining if the
proposal has received the requisite number of votes for approval. Thus, an
abstention and a broker non-vote will have the same effect as a vote against the
proposal.

                           THE BUSINESS OF EARTHLINK
 
OVERVIEW
 
    The Company is an Internet service provider ("ISP") that was founded to help
its members derive meaningful benefits from the extensive resources of the
Internet. The Company focuses on providing access, information, assistance and
services to its members to encourage their introduction to the Internet and to
provide them with a satisfying user experience.
 
    The Company provides its services through its EarthLink Network
TotalAccess-TM- software package, which is designed to simplify access to the
Internet through an online registration feature and a multimedia user interface.
This software permits members to browse the World Wide Web and the Internet
through the use of the latest Internet browsers from Netscape Communications
Corporation ("Netscape") and Microsoft Corporation ("Microsoft"), one or the
other of which is included in each copy of EarthLink Network TotalAccess, or
another third-party browser that a member may wish to use. Members connect to
the Company's network via telephone modem at speeds up to 56Kbps, cable modems,
ISDN lines or frame relay connections. The Company also provides useful
information and online resources to its members through its extensive World Wide
Web site. On this site, members can find technical assistance information, an
online newsletter, links to numerous categories of popular information and
entertainment and many other items and services designed to enhance members'
satisfaction with their Internet experience. In addition, the Company provides
members with six megabytes of free Web space, a free Personal Start Page-TM-,
24-hour customer and technical support, a bi-monthly printed newsletter and
other educational materials.
 
    The Company currently markets its services through print and broadcast
advertisements, an affinity marketing program, a member referral program and
other marketing activities. Its affinity marketing program includes
relationships with, among others, prominent retailers, print publications and
software and hardware companies. Member referrals have also been an important
source of new members, and the Company provides economic incentives (such as one
month's free access) to its members to encourage referrals.
 
    EarthLink also offers business services, including business Web site
hosting, high-speed ISDN communications capability and frame relay connectivity.
In addition, the Company offers promotional opportunities to members via
sponsorships through its Premier Partnership Program with advertising, marketing
and distribution partners.
 
STRATEGY
 
    The principal components of EarthLink's growth strategy are as follows:
 
    RAPIDLY EXPAND ITS MEMBER BASE THROUGH AGGRESSIVE MARKETING.  EarthLink
believes that a key to success in the competitive ISP market is to rapidly
expand its member base to establish a significant revenue base and to take
advantage of economies of scale. The Company has historically acquired members
primarily through its affinity marketing programs, advertising and referrals
from existing members.
 
    RETAIN EXISTING MEMBERS.  The sales, marketing and other costs of acquiring
new members are substantial relative to the monthly fee collected from such
members. Accordingly, the Company believes that a part of if its long-term
success largely depends on member retention. To that end, EarthLink will
continue to devote significant resources to expanding its 24-hour customer and
technical support, enhancing its network operations capability and refining and
maintaining its World Wide Web site. In addition, the Company will continue to
minimize call times by implementing a new call center and providing the
training, hardware and software tools that can assist the staff in identifying
and solving member problems thereby increasing member satisfaction and
retention.
 
                                       51
<PAGE>
    CONCENTRATE ON CORE COMPETENCIES BY LEASING NETWORK SERVICES AND LICENSING
SOFTWARE FROM THIRD PARTIES.  In order to maintain its focus on member needs,
the Company leverages the infrastructure and software development efforts of
others by leasing its dial-up point of presence ("POP") capacity from UUNET
Technologies, Inc. ("UUNET") and PSINet Inc. ("PSINet"), and licensing software
from companies such as Netscape and Microsoft. Upon closing of the transactions
contemplated by the Investment Agreement, the Company and its members will also
have access to Sprint points of presence and Sprint's related communications
network. The Company believes that this approach gives it flexibility to rapidly
expand its service coverage without the need for substantial capital
expenditures. The Company will continue to pursue this strategy so that, in
addition to its sales and marketing efforts, it can devote its principal
resources to improving its members' experience with the Internet.
 
EARTHLINK'S SERVICES
 
    EarthLink provides a variety of competitively-priced Internet services to
consumer and business members. The Company enables the majority of these
services through use of its EarthLink Network TotalAccess software package. This
software incorporates a telephone dialer and email functionality with several
leading third-party Internet access tools, including the latest browsers from
Netscape and Microsoft, thereby providing a functional, easy-to-use Internet
access solution for Windows 3.1, Windows 95 and Macintosh platforms. EarthLink
Network TotalAccess installation software automatically installs these and other
software applications on the member's computer. The simple point-and-click

multimedia registration system, permits online credit card registration,
allowing new EarthLink members to quickly access the Internet.

"Finance" and "Games." The Company's Web site provides a road map to the

assistance including technical support, account maintenance and service updates.
 
    NEWSGROUPS.  One of the most popular areas of the Internet is Usenet, a
collection of Internet discussion groups called "newsgroups." Usenet is a system
that is specifically designed to create and facilitate ongoing online

of these newsgroups discussing different topics.

email, online chat and other advanced tools for communication. The Internet
Rooms provide members with a powerful and easy way to establish Web sites
without having to rely on complicated programming languages such as HTML or FTP.
There is an annual fee of $29.95 for each Internet Room.
 
    PREMIER PARTNERSHIP PROGRAM.  As part of its strategy to generate additional
incremental revenue and leverage its current properties, the Company developed
the premium partnership program. The program consists of the following three
options: the "Platinum Package," the "Gold Package" and the "Silver Package."
Each package includes advertising in three separate areas: the Personal Start
Page, the Mall and the member newsletter, "bLink." The client is promised a
certain number of impressions, calculated by multiplying the reach times the
frequency times the population. This program allows the partner to reach the
Internet user in three different locations. EarthLink does not offer this
program to every company; rather, it is focusing on market segments that should
enhance the Internet experience of its member base.
 
    SUPPLEMENTAL SERVICES.  To augment its standard and premium services, the
Company provides its members with the following supplemental service options:
 
    ADDITIONAL MAILBOXES.  The Company provides additional electronic mailboxes

intended for those members who require more than one mailbox for colleagues,
employees or family members.
 
    DOMAIN NAME SERVICE.  EarthLink provides unique or vanity domain names for
those members who prefer an individualized address or plan to establish a
business Web site. These vanity domain names allow consumers and businesses to
customize their email and Web site addresses. EarthLink charges a one-time fee
of $75 to set up domain name service and assist members in establishing their
unique domain names. Members then pay an annual renewal fee to an Internet
domain registration agency.
 
    STAR EMAIL ADDRESSING.  EarthLink members desiring an unlimited choice of
email addresses (like "[email protected]" or "[email protected]") can purchase
star addressing. Within the star addressing scheme, all email goes into a
central mailbox, for easy processing to individual addresses at the same domain.
There is a one-time set-up fee of $125, but no monthly fee for maintaining the
service.
 
    INTERNATIONAL ROAMING SERVICE  EarthLink offers international roaming
services so that members who travel abroad can access their EarthLink accounts
and the Internet. The fee for roaming is a flat rate of 15 cents per minute plus
applicable fees, if any, charged by local and long distance carriers.
 
    800 SERVICE.  EarthLink provides 800 number dial-up service for members who
do not have access to a local POP. EarthLink charges members $24.95 per month
for five hours of 800 number service plus a one-time set-up fee of $25.00.
Additional hours are $4.95 per hour.
 
TECHNICAL DEVELOPMENT AND SERVICE ENHANCEMENT
 
    EarthLink places significant emphasis on expanding and refining its services
to enhance its members' Internet experience. EarthLink's technical staff is
engaged in a variety of technical development and
 
                                       54
<PAGE>
service enhancement activities and continuously reviews new third-party software
products and technology for potential incorporation into EarthLink's system and
services. A recent result of these efforts is a ground-up revision of EarthLink
Network TotalAccess, version 2.0, which was recently introduced. 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. EarthLink also regularly updates and expands the
online services provided through the EarthLink Web site. These activities
include organizing Web content and the development of online guides, help
screens and other user services and resources.
 
SALES AND MARKETING
 
    EarthLink's sales and marketing efforts consist of the following programs:
 
    ADVERTISING.  The Company advertises its services in print, electronic and
broadcast media. Included in most of these advertisements is a toll-free 800
number for contacting the Company's internal sales staff. When potential members
call a sales representative using this number, they are assigned a user name and
password, and are sent a copy of EarthLink Network TotalAccess software, which
they use to access their account and the Internet.
 
    Another component of EarthLink's advertising strategy involves maintaining a
presence at national trade shows such as Internet World and MacWorld, as well as
numerous local and regional trade shows. Additionally, the Company markets
through computer, Internet and related publications, and bundles EarthLink
Network TotalAccess software with a few of these publications.
 
    AFFINITY MARKETING PROGRAM.  EarthLink's affinity marketing program promotes
the Company through the distribution of the EarthLink Network TotalAccess
software package by its affinity marketing partners. These partners typically
bundle EarthLink Network TotalAccess software with their own goods or services
to create a package that gives potential members an incentive to establish an
EarthLink account. EarthLink's marketing partners include, among numerous
others, Best Buy Co., CNET, CompUSA, CyberMedia, Hard Rock Cafe America, Iomega,
MacMillan Publishing USA, SAM'S Club, Sony Entertainment, United Airlines and
Warner Bros.
 
    SPRINT ALLIANCE.  EarthLink's alliance with Sprint includes a marketing
agreement and distribution arrangement, which upon close of the transactions
contemplated by the Investment Agreement with Sprint will provide EarthLink with
access to Sprint's branded marketing and distribution channels in the
continental United States and a five-year commitment from Sprint to deliver a
minimum of 150,000 new members annually.
 
    MEMBER REFERRAL PROGRAM.  The Company believes that one of its most
important marketing tools is its existing members. In order to encourage members
to refer other users, the Company currently waives one month of standard access
service fees per referred member. Approximately 25 percent of the Company's new
membership has been generated by referrals.
 
OTHER PROGRAMS
 
    - ELITE PROGRAM. EarthLink recently launched the EarthLink Internet
      Technology for Education ("ELITE") program, which is designed to provide a
      cost-effective, flexible Internet access solution for colleges and
      universities. The Company has already won contracts with two colleges in
      Georgia and with the University of California, Los Angeles.
 
    - PARTNER PROGRAM. This program enables vendors, such as value-added
      resellers, retailers and other companies that target vertical markets, to
      resell EarthLink's dial-up Internet service, along with high-end business
      services, such as Web site hosting, ISDN, LAN ISDN and frame relay, to
      their customers. Through this partnership, these companies can deliver a
      complete Internet product and
 
                                       55
<PAGE>
      service offering to their customers by providing them with a full range of
      turn-key, Internet business solutions.
 
MEMBERS, POPS AND NETWORK INFRASTRUCTURE
 
    As of December 31, 1997, the Company had approximately 420,000 members. The
Company presently provides its members with Internet access primarily through
UUNET's and PSINet's nationwide system of Points of Presence ("POPs").
Substantially all of the Company's members access the EarthLink Network and the
Internet by dialing into local POPs. Of these, the Company owned 58 POP sites in
California and offered additional access through 841 UUNET POPs and 374 PSINet
POPs, to which it had access on a non-exclusive basis. The alliance with Sprint
includes a Network Service Agreement, which upon closing of such transaction
will provide EarthLink members access to POPs owned and operated by Sprint. The
inability or unwillingness of these third-party network providers to provide POP
access to EarthLink's members, or the Company's inability to secure alternative
POP arrangements, could have a material adverse effect on the Company.
 
    For members located in a geographic area not presently serviced by a local
POP, the EarthLink Network can be accessed by a toll-free number for which the
Company bills members on an hourly usage basis. The Company's POP sites are
connected to the Internet primarily through its network hub in Pasadena. The
Company's network hub is in turn connected directly to the Internet via
redundant high-speed fiber optic data lines obtained from various vendors. The
Company, however, does not maintain fully redundant data center and network hub
facilities. Any accident, incident or system failure that causes interruptions
in the Company's operations could have a material adverse effect on the
Company's ability to provide Internet services to its members, and, in turn, on
the Company. However, the Company has invested in measures to minimize the
effects of communications line failures, loss of electrical service, fire,
earthquakes and other adverse occurrences.
 
MEMBER AND TECHNICAL SUPPORT
 
    The Company believes that reliable member and technical support is critical
to retaining existing and attracting new members. The Company currently provides
the following types of member and technical support: (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, the Company provides dedicated support for its business members.
 
    EarthLink's call center is served by a state-of-the-art Lucent Definity
telephone switch, which currently handles approximately 30,000 calls a day. The
system is easily scaleable to accommodate call volume growth. The Company
actively evaluates its call center facilities so as to deliver more effective
and efficient services to its members.
 
SUPPLIER RELATIONSHIPS
 
    The Company is dependent on third-party software and hardware vendors to
provide the Company with much of its Internet software and hardware, including
the latest World Wide Web browser software that the Company licenses from
Netscape and Microsoft. Failure of the Company's suppliers to provide software
or hardware in the quantities, at the quality levels or at the times required by
the Company, or an inability by the Company to develop alternative sources of
supply if required, could have a material adverse effect on the Company.
 
COMPETITION
 
    The Internet services market in which the Company operates is extremely
competitive, and the Company expects competition in this market to intensify in
the future. The Company's current and
 
                                       56
<PAGE>
prospective competitors include many large companies that have substantially
greater market presence and financial, technical, marketing and other resources
than the Company. The Company competes (or in the future is expected to compete)
directly or indirectly with the following categories of companies: (i) national
and regional ISPs, such as BBN, MindSpring, PSINet and UUNET; (ii) established
online services such as America Online, Prodigy and the Microsoft Network; (iii)
nonprofit or educational ISPs; (iv) national telecommunications companies, such
as AT&T and MCI; (v) Regional Bell Operating companies; and (vi) cable
operators, such as Comcast, TCI and Time Warner.
 
    The entry of new competitors would result in greater competition for the
Company. In addition, competitors in the telecommunications industry may be able
to provide members with reduced communications costs in connection with their
Internet access services, reducing the overall cost of Internet access and
significantly increasing pricing pressures on the Company. There can be no
assurance that the Company will be able to offset the adverse effect on revenues
of any necessary price reductions resulting from competitive pricing pressures.
 
    The Company believes that its ability to compete successfully in the
Internet services market depends on a number of factors, including market
presence; the adequacy of the Company's customer and technical support services;
the capacity, reliability and security of its network infrastructure; the ease
of access to and navigation of the Internet provided by the Company's services;
the pricing policies of the Company, its competitors and its suppliers; the
timing of introductions of new services by the Company and its competitors; the
Company's ability to support existing and emerging industry standards; and
industry and general economic trends. There can be no assurance that the Company
can maintain or develop the financial resources, technical expertise or
marketing and support capabilities to compete successfully.
 
PROPRIETARY RIGHTS
 
    GENERAL.  EarthLink relies on a combination of copyright, trademark, patent
and trade secret laws and contractual restrictions to establish and protect its
technology. It is EarthLink's policy to require employees and consultants and,
when possible, suppliers and distributors, to execute confidentiality agreements
upon the commencement of their relationships with the Company. There can be no
assurance that the steps taken by the Company will be sufficient to prevent
misappropriation of its technology and other proprietary property or that the
Company's competitors will not independently develop technologies that are
substantially equivalent or superior to the Company's technology.
 
    From time to time, the Company has received communications from third
parties alleging that certain of the names or trademarks for the Company's
services infringe the trademarks of such third parties. To date, no such claims
have had an adverse effect on the Company's ability to market and sell its
services. However, there can be no assurance that those claims will not have an
adverse effect in the future or that other parties will not assert infringement
claims against the Company in the future with respect to current or future
services.
 
    LICENSES.  EarthLink has obtained authorization, typically in the form of a
license, to distribute third-party software incorporated in EarthLink Network
TotalAccess. Applications licensed by the Company include Netscape Communicator
(which automatically renews each December for additional one-year terms unless
either party terminates the license on 120 days notice), Microsoft Internet
Explorer (which automatically renews each December for additional one-year
terms, although either party may terminate the license at any time on 30 days
notice), and MacTCP software from Apple (which automatically renews each
December for additional one-year terms unless either party terminates the
license on twelve-month notice). The only software in the EarthLink Network
TotalAccess package that is developed by the Company is the front-end and
installation/registration program. The Company currently intends to maintain or
negotiate renewals of existing software licenses and authorizations. The Company
may want or need to license other applications in the future. The failure to
renew existing software licenses or the
 
                                       57
<PAGE>
Company's inability to license additional applications could have a material
adverse effect on the Company.
 
    TRADEMARKS.  "EarthLink Network-Registered Trademark-," "EarthLink Network
TotalAccess-TM-," "bLink-TM-," "The Arena-TM-," "All the Internet You Can
Eat-TM-," "It's Your Internet-TM-," "Personal Start Page-TM-",
"StarterSite-TM-", "the Mall-TM-", and the EarthLink logo are trademarks of the
Company.
 
GOVERNMENT REGULATION
 
    The Company provides Internet services, in part, through data transmissions
over public telephone lines. These transmissions are governed by regulatory
policies establishing charges and terms for wire line communications. The
Company currently is not subject to direct regulation by the Federal
Communications Commission (the "FCC") or any other governmental agency, other
than regulations applicable to businesses generally. However, in the future the
Company could become subject to regulation by the FCC or another regulatory
agency as a provider of basic telecommunications services. The FCC has
considered the issue of whether Internet service providers ("ISPs") should be
subject to access charges and regulation, and has determined that it would not
adopt such regulations. There are no active proceedings considering these
specific issues at this time. The FCC has announced, however, that it will be
issuing a Notice of Proposed Rule Making ("NPRM") to explore proposals to create
incentives for companies to make the most efficient use of the telephone network
for Internet and other information services. While the FCC has announced that it
does not intend for this Notice of Proposed Rule Making to consider the
imposition of access charges or regulations on ISPs, it could result in the
creation of more competition for the Company. In addition, the FCC could reopen
and reconsider these issues at any time.
 
    The Telecommunications Act of 1996 (the "Telecommunications Act") contains
certain provisions that lift, or establish procedures for lifting, certain
restrictions relating to the regional Bell operating companies' ("RBOCs")
ability to engage directly in the Internet access business. The
Telecommunications Act also makes it easier for national long distance carriers,
such as AT&T, to offer local telephone service. In addition, the
Telecommunications Act allows the RBOCs to provide electronic publishing of
information and databases. The same regulations that permit ISPs to operate
outside of the regulations applied to carriers also permits other providers of
Internet services, including voice and facsimile services, to operate more
easily. These could provide additional sources of competition for the Company.
As the FCC auctions wireless spectrum and relaxes the restraints for the use of
spectrum, it will be easier for additional wireless competitors to enter into
the marketplace. Competition from these companies could have an adverse effect
on the Company's business.
 
    The Telecommunications Act, through the portion commonly known as the "1996
Communications Decency Act," imposed fines for certain uses of the Internet, and
the provision of access to indecent and obscene services. These provisions were
struck down as unconstitutional by the Supreme Court of the United States in
June of 1997. On March 12, 1998, the Senate Commerce Committee approved two
bills that reconstruct the unconstitutional provisions of the 1996
Communications Decency Act. While it is too early to determine the ultimate
course of these bills, and to evaluate the constitutionality of the proposals,
there is a possibility that these provisions, if enacted, could pose possible
liability on ISPs.
 
    Due to the increasing 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, user privacy, pricing, libel, intellectual property
protection and infringement and technology export and other controls.
Legislation has been introduced to define and protect citizens from illegal
Internet gambling. Other Internet-related legislation has been introduced which
may limit commerce and discourse on the Internet. The FCC currently is
considering (i) whether ISPs are information service providers or
telecommunications providers; (ii) whether ISPs are legally required to
contribute to the Universal Service Fund; (iii) how various companies in the
Internet/information/data/telephony service provider field should be classified;
and (iv) whether ISPs should benefit from the Universal Service Fund. Changes in
the regulatory environment
 
                                       58
<PAGE>
relating to the Internet access industry, including regulatory changes that
directly or indirectly affect telecommunications costs or increase the
likelihood or scope of competition from RBOCs or others, could have a material
adverse effect on the Company.
 
EMPLOYEES
 
    As of December 31, 1997, the Company employed 785 people on a full-time
basis, including 98 sales and marketing personnel, 579 operations and customer
and technical support representatives and 108 administrative personnel. As of
that date, the Company also employed 22 people on a part-time basis. None of the
Company's employees are represented by a labor union, and the Company is not a
party to any collective bargaining agreement.
 
PROPERTIES
 
    EarthLink's corporate headquarters are located in an 85,500 square-foot
facility in Pasadena, California. In June 1997, the Company amended the lease
for its corporate headquarters facility. Under the amended lease, the lessor
will provide improvements costing up to $1.4 million and convert approximately
45,000 square feet of the existing facility to office space. Base rent is
currently $73,000 per month. Under the amended lease, the Company increased the
existing irrevocable letter of credit to the lessor from $200,000 to $450,000.
The Company has an option to extend this lease for an additional five years at
the then prevailing market rate following its September 30, 2007 expiration.
EarthLink's data center and its primary data hubs are housed in a 55,000 square
foot facility adjacent to its headquarters. EarthLink's lease for this space has
an initial ten-year term at $66,000 per month for the first 60 months and
$77,000 per month for the remaining 60 months. The Company has an option to
extend this lease for an additional ten years at the then prevailing market
rate. In addition to the Company's corporate headquarters and data center, the
Company also leases approximately 7,200 square feet of office space in Los
Angeles that presently houses a secondary portion of the Company's data center
operations and network hub; however, the Company anticipates that these
operations will be moved to its Pasadena data center in 1998. The lease for this
space expires July 31, 1999 and currently provides for rental payments of
approximately $10,000 per month.
 
LEGAL PROCEEDINGS
 
    The Company is not currently involved in any legal proceedings that it
believes could have, either individually or in the aggregate, a material adverse
effect on its business or financial condition. There are proceedings pending
before the FCC that could affect the ISP industry and the means by which ISPs
such as the Company conduct their business. See "Business--Government
Regulation." The Company is not a party to these proceedings.

          EARTHLINK--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 herein.
 
OVERVIEW
 
    The Company has experienced net losses since it commenced operations. Net
losses were approximately $6.3 million from inception through 1995, $31.1
million for 1996, and $29.9 million for the year ended December 31, 1997. As of
December 31, 1997, the Company had an accumulated deficit of approximately $66.1
million (exclusive of $1.3 million of losses incurred while the Company was an S
Corporation for tax purposes, which, upon the Company's conversion to C
Corporation status in June 1995, were charged to the Company's capital
accounts). 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.
 
    The market for the Company's services is rapidly evolving and is
characterized by an increasing number of market entrants who have introduced new
products and services for Internet. The Company and its prospects must be
considered in light of the risks, expenses and difficulties frequently
encountered by companies in the new and rapidly evolving market for Internet
services and products.

1997 COMPARED TO 1996
 
    RECURRING REVENUES.  Recurring revenues consist of monthly fees charged to
members for Internet access and other monthly services. Recurring revenues are
recognized over the period for which the
 
                                       60
<PAGE>
services are provided. Recurring revenues increased $46.1 million or 171% from
1996 to 1997 due to the increase in the Company's member base from 227,000 to
420,000 during 1997.
 
    OTHER REVENUES.  Other revenues generally represent one-time non-refundable
set up fees and are recognized as earned.

</TABLE>
 
    Other revenues increased $600,000 or 11% from 1996 to 1997. Due to
competitive pricing and other pressures, the Company waives set up fees for
dial-up members acquired through certain affinity marketing partnerships. This
caused a decrease in dial-up set up fees earned during 1997. This trend is
expected to continue for dial-up set up fees. During 1997, the Company began to
aggressively promote its Web hosting and high speed access services and in the
fourth quarter began to capitalize on incremental revenue activities. The
decline in dial-up set up fees was offset by increases in the other set up fees
and revenues attributable to the Company's Web hosting, high speed access
services and related products.
 
    COST OF RECURRING REVENUES.  Cost of recurring revenues principally includes
telecommunications costs such as fees paid to UUNET and PSINet for local access
to their nationwide systems of POPs and depreciation expense on equipment used
in network operations for ongoing member services.
 
    Cost of recurring revenues increased $19.5 million due to the increase in
the Company's member base but decreased from 69% of recurring revenues in 1996
to 52% of recurring revenues in 1997. The decrease from 1996 to 1997 was
primarily due to the Company's ability to effectively manage communications
costs and economies of scale to reduce per member costs as the total member base
expanded. Until October 1996 the Company 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. The Company's agreement with UUNET was amended as of
October 1996 to change the basis of per member costs to peak port hours. In June
1997, UUNET agreed to waive monthly revenue minimums, and excess hours fees, and
peak service user targets during the six months ended December 31, 1997. In
return, EarthLink agreed not to invoke its early termination right until
September 1998. If usage becomes more concentrated during peak times, the fees
paid by the Company to UUNET will increase, thereby adversely affecting the
Company's operating margins. Under the Company's agreement with PSINet, the
Company pays PSINet a fixed monthly fee for each customer accessing the
Company's services through a PSINet POP. As the Company continues to expand, the
Company anticipates that it may build and use additional Company-owned POPs in
those geographical areas where there is a sufficient concentration of members to
support the cost of such investment. Upon consummation of the transactions
contemplated by the Investment Agreement with Sprint, the Company's members will
also have access to Sprint's network of POPs.

    COST OF OTHER REVENUES.  Cost of other revenues principally includes
expenses related to the registration of new members such as licensing fees for
software, software duplication costs commissions and bounties paid to third
parties for referring new members to the Company.

</TABLE>
 
    Cost of other revenues increased $700,000 or 26% during 1997. The increase
was due to growth in affinity marketing partnerships and payment of the related
bounties. The growth in bounties was partially offset by a decrease in royalty
expense due to the renewal of various contracts under more favorable terms. The
increase in the total cost of other revenues as a percentage of other revenues
was attributable to the decrease in other revenues, specifically, dial-up set up
fees.
 
    SALES AND MARKETING.  Sales and marketing expenses consist primarily of
sales commissions, salaries, cost of promotional material, advertising, travel
and third-party sales commissions. Sales and marketing expenses increased $5.8
million or 38% during 1997. The increase was primarily due to the emphasis on
marketing the Company's services, expanding sales and marketing efforts
nationwide, increased sales commissions and increased marketing personnel
headcount. The Company does not defer sales, marketing or other direct costs
associated with the acquisition of members.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of costs associated with the accounting and human resources
departments, professional expenses, rent, bad debts and compensation related to
certain executive officers. General and administrative expenses increased $3.8
million or 36% due to increases in bad debt, payroll, rent, depreciation
expenses and credit card fees. Bad debt expense was $2.5 million or 7.7% of
total revenue 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 4.4%
of revenue in 1997. The increase in bad debt was due to management's review and
elimination of accounts with questionable payment history and the compression of
the Company's collection cycle. The rise in payroll costs was primarily due to
growth in headcount. Personnel engaged in general and administrative activities
increased from 85 to 110 during 1997. The rise in depreciation expense is due to
the acquisition of office equipment and the build-out of leasehold improvements.
The increase in credit card processing fees was primarily due to the increase in
the Company's member base.
 
    OPERATIONS AND MEMBER SUPPORT.  Operations and member support expenses
consist primarily of costs associated with technical support and member service
and costs to register and maintain member accounts. Employees engaged in
operations and member support activities increased from 401 to 565 during 1997.
The increase of $15.4 million or 98% reflects management's efforts to retain
existing members by devoting significant resources to expanding technical
support and network operations capabilities. During 1997 the Company created a
new call center and invested in training programs and hardware and software to
solve member problems. The Company intends to continue to invest in this area.
 
1996 COMPARED TO 1995
 
    REVENUES.  Recurring revenues increased $24.5 million or more than 1,000%
during 1996 as a result of an increase in the number of EarthLink members. The
increase in revenues was partially offset by credits
 
                                       62
<PAGE>
given to members under the Company's member referral program. Under this
program, the Company waives one month of standard service fees in consideration
for each new member referred by an existing member. This waived service fee
results in a reduction of revenues. The increase in other revenues during 1996
was primarily due to the increase in the number of new members during that
period and one-time set up fees collected from those new members. From time to
time, the Company waives the one-time set up fee it charges new members as a
result of competitive pricing and other pressures.
 
    COST OF REVENUES.  Cost of recurring revenues increased from 44% of
recurring revenues in 1995 to 69% of recurring revenues in 1996 due the
Company's expansion to nationwide service through its relationship with UUNET.
The Company paid UUNET a fixed monthly fee per member plus a variable amount
based on customer usage in excess of a threshold number of hours per month. The
Company's agreement with UUNET was amended as of October 1996 so that the key
variable component is peak usage rather than hourly usage.
 
    SALES AND MARKETING.  Sales and marketing expenses consisted primarily of
sales commissions, salaries, cost of promotional material, advertising, travel
and third-party sales commissions. EarthLink's principal strategy has been to
rapidly expand its customer base and increase its market share of the under
penetrated market for Internet access services. To realize this strategy, the
Company has aggressively invested in sales and marketing. This strategy required
substantial initial cash outlays which outpaced the resultant growth in
revenues. In the latter part of 1996 EarthLink's marketing efforts emphasized
the variety of services available to business members, including business Web
sites, high-speed ISDN communications capability, high-speed frame relay
connections and Internet access through corporate Intranets.
 
    GENERAL AND ADMINISTRATIVE.  Since inception, general and administrative
expenses have increased as a result of increased employee headcount, rent,
depreciation and credit card fees. During 1996, the Company hired a number of
senior management personnel, moved into a new headquarters building and engaged
professional consultants to assist in the development of an administrative
infrastructure to accommodate anticipated increases in the number of members and
employees, which resulted in a significant increase in general and
administrative expenses as compared to 1995. General and administrative expenses
for 1996 included bad debt expense of $2.5 million which resulted from
difficulties in billing and in disconnecting late-paying members on a timely
basis. In addition, in September 1996, the Company issued 37,500 shares of
Common Stock as consideration for the termination of a consulting agreement. The
value of the stock, $413,000, was included in general and administrative
expenses for the year ended December 31, 1996.
 
    OPERATIONS AND MEMBER SUPPORT.  Operations and member support expenses
consist primarily of expenses associated with technical support and member
services to register and maintain member accounts. These expenses have increased
significantly since the Company's inception. This trend reflects the costs
associated with building a member service organization to support the Company's
member base and anticipated member growth. Employees engaged in operations and
member support activities increased from 118 to 401 during 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has not generated net cash from operations since its inception.
The Company has funded its operations primarily through private and public sales
of equity securities, borrowings from third parties and lease financing. Cash
used in operating activities was approximately $3.6 million, $16.2 million and
$21.3 million during the three years ended December 31, 1997, respectively.
 
    Cash used in investing activities has consisted primarily of equipment
purchases for POP and network expansion. Capital expenditures amounted to
approximately $2.8 million, $18.8 million and $14.5 million, respectively, for
the three years ended December 31, 1997. During 1997 the Company purchased the
rights to subscribers and related assets of Internet in a Mall, a Tarzana,
California based Internet access provider
 
                                       63
<PAGE>
at a cost of approximately $1.4 million. The Company estimates that capital
expenditures for 1998 will be approximately $18.5 million including network
enhancements, data center expansion, and procurement of telecommunication and
office equipment and furniture and fixtures. Where feasible, the Company will
seek to finance certain of these expenditures through capital leases.
 
    Cash provided by financing activities provided the Company with
approximately $8.2 million, $38.3 million and $49.8 million during the three
years ended December 31, 1997, respectively. The Company's financing activities
have consisted of the private sale of debt, the public and private sale of
equity securities and capital lease transactions primarily for equipment. The
Company issued 367,155 shares of Common Stock at $0.82 per share, 827,085 shares
of Common Stock at $1.81 per share and 921,745 at $4.84 per share on March 10,
1995, June 19, 1995 and October 31, 1995, respectively. As a result of these
placements, the Company raised, in the aggregate $6,258,000 during 1995. The
Company issued 45,485 shares of Common Stock at $4.84 per share and 25,000
shares of Common Stock at $4.84 per share on January 18, 1996 and March 20,
1996, respectively. On May 6, 1996, the Company issued 852,460 shares of common
stock at $9.76 per share in a private placement. On September 24, 1996, the
Company issued 2,727,273 shares of Series A Convertible Preferred Stock at $5.50
per share which was converted into 1,363,624 shares of Common Stock upon the
close of the Company's initial public offering in January 1997. As a result of
these placements, EarthLink raised, in the aggregate, net proceeds of $22.7
million during 1996. In January 1997, the Company sold 2,000,000 shares of
Common Stock in its initial public offering. Net proceeds from the offering were
approximately $22.8 million. In February 1997, the underwriter of the public
offering exercised its over allotment option and purchased and sold an
additional 284,750 shares of Common Stock. Net proceeds to the Company were
approximately $3.4 million. On September 19, 1997, the Company closed a private
placement of 1,459,759 shares of its unregistered restricted Common Stock. Net
proceeds from the offering were approximately $15.4 million. Capital lease
obligations generally result from the sale and leaseback of equipment. During
the three years ended December 31, 1997, the Company financed the acquisition of
data processing and office equipment amounting to approximately $556,000, $11.3
million and $10.5 million, respectively, by entering into a number of 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.
During the second quarter of 1996, the Company received short-term debt
financing (issued in the form of 10% Promissory Notes that were to mature in
June 1997) of $2.95 million from a limited number of investors, including
certain directors and existing stockholders. The holders of $725,000 of such
notes converted the notes into 55,767 shares of Common Stock upon closing of the
Company's initial public offering. The remaining $2,225,000 of 10% promissory
notes were paid in full in January 1997.
 
    In connection with an amendment of its strategic network services
relationship with UUNET, in October 1996, the Company issued a $5.0 million,
one-year promissory note to UUNET. This note bears interest at 10.25% and is
convertible into up to approximately 391,515 shares of Common Stock. The note
was amended in October 1997 to extend the due date for an additional year. On
March 31, 1998, UUNET converted the note into 391,515 shares of Common Stock.
 
    As of December 31, 1996 and December 31, 1997, the Company had cash and cash
equivalents of approximately $4.0 million and $16.5 million, respectively. The
Company believes that available cash will be sufficient to meet the Company's
operating expenses and capital requirements for at least the next 12 months.
Under the terms of its announced alliance with Sprint Corporation and assuming
that the Sprint transactions close, EarthLink will obtain approximately $24
million in cash and have available up to $100 million in convertible debt
financing over three years. 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 organization,
 
                                       64
<PAGE>
information systems and research and development activities, the availability of
hardware and software provided by third-party vendors and other factors. The
timing and amount of such capital requirements cannot accurately be predicted.
If capital requirements vary materially from those currently planned, the
Company may require additional financing sooner than anticipated. The Company
has no commitments for any additional financing, and there can be no assurance
that any such commitments can be obtained on favorable terms, if at all. Any
additional equity financing may be dilutive to the Company's stockholders, and
debt financing, if available, may involve restrictive covenants with respect to
dividends, raising future capital and other financial and operational matters.
If the Company is unable to obtain additional financing as needed, the Company
may be required to reduce the scope of its operations or its anticipated
expansion, which could have a material adverse effect on the Company.
 
YEAR 2000
 
    Many existing computer programs use only two digits to identify a year.
These programs were designed and developed without considering 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 (the "Year 2000 Phenomenon"). The Company utilizes software, computer
technology and other services provided by third-party vendors that may not be
Year 2000 Phenomenon ready. Much of the third-party software, computer
technology and services is not essential to the Company's operations. However,
as discussed elsewhere herein, the Company is dependent on UUNET and PSINet for
network communications services and Microsoft and Netscape for Web browser
software. The Company is also indirectly dependent on the institutions involved
in processing the Company's members' credit card payments for the Company's
services. The failure of the software and computing systems of these and other
third-party vendors to be Year 2000 Phenomenon ready could have material adverse
effects on the Company. The Company has assessed its proprietary software and
systems and has determined them to be Year 2000 Phenomenon ready. However, the
Company is currently assessing the Year 2000 Phenomenon readiness of its
third-party supplied software, computer technology and other services. Based
upon the results of this assessment, the Company will develop and implement, if
necessary, a remediation plan with respect to third-party software, computer
technology and services which may fail to be Year 2000 Phenomenon ready.
Management anticipates that the Company's business, including components thereof
provided by third-party vendors, will be Year 2000 Phenomenon ready by 2000. At
this time, the expenses associated with this assessment and potential
remediation plan cannot presently be determined.

(1) SFAS No. 128, "Earnings per Share" and Staff Accounting Bulletin No. 98
    require companies, such as EarthLink, that incorporated the SAB 83 concept
    of "cheap stock" in determining pre-IPO EPS data to restate EPS data to
    conform to SFAS 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.

                        PRO FORMA FINANCIAL INFORMATION
 
    The following unaudited pro forma condensed combined financial statements
give effect to the acquisition by Newco of the Sprint Internet Passport business
("SIP") of Sprint in a transaction to be accounted for as a purchase. The
unaudited pro forma balance sheet is based on the balance sheet of the Company
included elsewhere in this Proxy Statement/Prospectus and the assets acquired
and liabilities assumed from SIP and Sprint and has been prepared to reflect the
acquisition by Newco of SIP as of December 31, 1997. The unaudited statement of
operations is based on the statement of operations of the Company and the
statement of revenues and direct expenses of SIP appearing elsewhere in this
Proxy Statement/Prospectus, and combines the results of operations of the
Company and of SIP for the year ended December 31, 1997 as if the acquisition
occurred on January 1, 1997. 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 historical financial statements and
notes thereto of the Company both included elsewhere in this Proxy
Statement/Prospectus. The historical statement of revenues and direct expenses
of SIP is 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 Newco.
 
    The purchase price paid by Newco will consist of approximately 4.1 million
shares of Convertible Preferred Stock. The Convertible Preferred Stock has been
valued at $135,000,000. In exchange for the Convertible Preferred Stock, the
Company will obtain SIP's customer base of approximately 130,000 members, cash
of $23,750,000 from Sprint, and Sprint will provide access to $100 million in
convertible debt financing. Sprint and Newco have also entered into a Marketing
Agreement and Newco will obtain access to Sprint's data network. Newco is
acquiring no other assets of SIP or Sprint. Accordingly, the purchase price will
be allocated to the cash and intangible assets acquired. For purposes of this
pro forma information, the purchase price has been allocated to cash and
intangible assets. The excess of the purchase price over the fair value of the
assets acquired has been allocated to goodwill. The final allocation may differ
from that used in the unaudited pro forma condensed combined financial
statements. The acquisition will be accounted for using the purchase method.
 
    Sprint began offering Internet access in the fourth quarter of 1996 and
reports this operation within its Emerging Businesses Segment (the "Group").
Sprint maintains the financial information relative to the Internet subscribers
in the Group. Sprint maintains 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. It however, does not separately maintain and account for other costs
and expenses to operate this business. Newco is unable to determine or estimate
these costs on a historical and pro forma basis. In addition, Sprint does 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.

    Pro forma adjustments are as follows:
 
        a. This adjustment reflects the cash acquired of $23,750,000.
 
        b. This adjustment reflects the fair value of the intangible assets
    acquired consisting of a customer base of $65,000,000, intangible assets
    related to Sprint's provision of customers and the co-branding feature of
    the Marketing Agreement of $20,000,000 and the excess of consideration over
    the fair value of assets acquired totaling $34,718,000.
 
        c. Represents incremental acquisition costs directly attributable to the
    transactions consisting of primarily investment banking, legal and
    accounting professional fees.
 
        d. These adjustments reflect the issuance of approximately 4.1 million
    shares of Convertible Preferred Stock in connection with the transactions
    contemplated by the Investment Agreement at estimated fair value. The
    Convertible Preferred Stock will pay dividends for the first five years in
    the form of increases in its Liquidation Value ("Liquidation Accretion
    Dividends"), at a rate of 3% of the Liquidation Value. Thereafter, the
    Convertible Preferred Stock will pay a cash dividend of 3% for 15 years
    increasing from 8% to 12% in years 21 through 23.

              NOTES TO PRO FORMA COMBINED STATEMENT OF OPERATIONS
 
    Pro Forma adjustments are as follows:
 
        a. This entry reflects the amortization of intangible assets on a
    straight-line basis as follows: (i) customer base amortized over 18 months,
    (ii) the Marketing Agreement amortized over two periods: (A) five years,
    which is the life of the portion of the contract related to Sprint's
    provision of customers; and (B) ten years, which is the overall contract
    life relative to the co-branding feature, and (iii) 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.
 
        b. Newco will acquire no depreciable assets of SIP. This adjustment
    eliminates the depreciation expense recorded by SIP.
 
        c. This adjustment reflects the Liquidation Dividends based upon a 3%
    Liquidation Value accretion dividend ($3,736,000) 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 ($5,619,000).
 
        d. Pro forma per 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, 1997, but excludes any
    shares to be purchased by Sprint in the Offer. As of December 31, 1997,
    EarthLink had reserved for issuance 1,688,611 shares upon the exercise of
    outstanding employee stock options, 391,515 shares reserved for issuance
    pursuant to its Convertible Note issued to UUNET Technologies, Inc. and
    887,647 reserved for issuance upon exercise of outstanding warrants. These
    common stock equivalents and 4.1 million shares of the Convertible Preferred
    Stock have been excluded from the calculation as their effect is
    antidilutive. The pro forma per share data also reflects the exchange on a
    one for one basis of common stock between the Company and Newco upon
    consummation of the Merger.

                   DESCRIPTION OF THE CAPITAL STOCK OF NEWCO
 
GENERAL
 
    Pursuant to the Certificate of Incorporation of Newco, Newco is authorized
to issue a total of 75 million shares of capital stock, consisting of 50 million
shares of common stock, $.01 par value per share (the Newco Common Stock), and
25 million shares of preferred stock, $.01 par value per share (the "Preferred
Stock").
 
COMMON STOCK
 
    Holders of Newco Common Stock are entitled to one vote per share on all
matters on which the holders of common stock are entitled to vote. Subject to
the preferential rights of holders of Preferred Stock, including the Convertible
Preferred Stock, holders of Newco Common Stock are entitled to receive dividends
as may be declared by the Board of Directors from time to time out of funds
legally available therefor. Holders of Newco Common Stock have no cumulative
voting rights, preemptive, conversion, redemption or sinking fund rights, In the
event of a liquidation, dissolution or winding-up of Newco, holders of shares of
Newco Common Stock are entitled to share equally and ratably in the assets of
Newco, if any, remaining after payment of all debts and liabilities of Newco and
the liquidation or other preferences of any then-outstanding shares of Preferred
Stock, including the Convertible Preferred Stock. The Newco Common Stock to be
issued to holders of the Company Common Stock in the Merger will be, when
issued, fully paid and nonassessable. The rights, preferences and privileges of
holders of shares of Newco Common Stock are subject to those of any series of
Preferred Stock which Newco may issue from time to time in the future.
 
PREFERRED STOCK
 
    The Board of Directors of Newco is authorized by its Certificate of
Incorporation to provide for the issuance, without stockholder approval, of
shares of Preferred Stock in series, and to establish from time to time the
number of shares to be included in each such series, and to fix the designation,
powers, preferences and rights of the shares of each such series and the
qualifications, limitations or restrictions thereof. Any Preferred Stock so
issued may rank senior to the Newco Common Stock with respect to the payment of
dividends or amounts upon liquidation, dissolution or winding up of Newco, or
both. In addition, any such shares of Preferred Stock may have voting rights.
The issuance of Preferred Stock, as established by the Board of Directors,
could, among other things, adversely affect the voting power of the holders of
Common Stock and, under certain circumstances, make it more difficult for a
third party to gain control of the Company, discourage bids for the Common Stock
(at a premium or otherwise), or otherwise adversely affect the market price of
the Company Common Stock.
 
    The Convertible Preferred Stock will be established as of the Effective Time
of the Merger pursuant to the Certificate of Designation the proposed form of
which is attached hereto as Appendix C, to be filed with the Secretary of State
of Delaware on such date. See "Company Stockholder Vote Matters --Proposal No.
2--Approval for the Issuance of Convertible Preferred Stock"
 
CERTAIN CHARTER AND BYLAW PROVISIONS
 
    Following the consummation of the Merger, Newco will be subject to the
"business combination" statute of the DGCL. This statute 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 the
business combination is approved in a prescribed manner, such as the approval of
a majority of certain members of the Board of Directors. The term "business
combination" includes mergers and stock and asset sales. An "interested
stockholder" is a person who, together with affiliates and associates, owns (or
within three years, did own) 15% or more of the corporation's voting stock. The
effect of this statute could, among other things, make it
 
                                       79
<PAGE>
more difficult for a third party to gain control of Newco discourage bids for
the Newco Common Stock at a premium or otherwise adversely affect the market
price of the Newco Common Stock.
 
LIMITATION OF DIRECTORS' AND OFFICERS' LIABILITY; INDEMNIFICATION
 
    Newco has included in its Certificate of Incorporation provisions that limit
the personal liability of its officers and directors for monetary damages for
breach of their fiduciary duty of directors, except for liability that cannot be
eliminated under the DGCL. The Certificate of Incorporation provides that, to
the fullest extent provided by the DGCL, directors of the Company will not be
personally liable for monetary damages for breach of their fiduciary duty as
directors. The DGCL does not permit a provision in a corporation's certificate
of incorporation that would eliminate such liability (i) for any breach of their
duty of loyalty to Newco or its stockholders, (ii) for acts or omissions not in
good faith or that involve intentional misconduct or a knowing violation of law,
(iii) for any unlawful payment of a dividend or unlawful stock repurchase or
redemption, as provided in Section 174 of the DGCL, or (iv) for any transaction
from which the director derived an improper personal benefit.
 
    While these provisions provide directors with protection from awards for
monetary damages for breaches of their duty of care, they do not eliminate such
duty. Accordingly, these provisions will have no effect on the availability of
equitable remedies such as an injunction or recission based on a director's
breach of his or her duty of care. The provisions described above apply to an
officer of a corporation only if he or she is a director of such corporation and
is acting in his or her capacity as director, and do not apply to the officers
of the corporation who are not directors.
 
    Newco's Bylaws provide that, to the fullest extent permitted by the DGCL,
Newco may indemnify its directors, officers and employees. The Bylaws further
provide that Newco may similarly indemnify its other employees and agents. In
addition, Newco anticipates that each director will enter into an
indemnification agreement with Newco pursuant to which Newco will indemnify such
director to the fullest extent permitted by the DGCL. At present, there is no
pending litigation or proceeding involving a director or officer of Newco in
which indemnification is required or permitted, and Newco is not aware of any
threatened litigation or proceeding that may result in a claim for such
indemnification.

To the Board of Directors and Stockholders
of EarthLink Network, Inc.
 
    In our opinion, the accompanying balance sheet and the related statements of
operations, of changes in stockholders' equity (deficit) and of cash flows
present fairly, in all material respects, the financial position of EarthLink
Network, Inc. at December 31, 1996 and 1997, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1997, 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 FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION
 
    EarthLink Network, Inc. ("EarthLink" or the "Company") was organized on May
26, 1994 as a California corporation and reincorporated in 1996 as a Delaware
corporation. 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.
 
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. Such revenues are recorded as
earned.
 
CASH AND CASH EQUIVALENTS
 
    All 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
 
    Commencing in 1995, the Company began to bill 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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
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 deferred financing and professional
service costs, prepaid lease guarantee costs, goodwill, rights to client lists
and a covenant not to compete. 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 three 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
$937,000, $3.2 million and $5.1 million, respectively, for the three years ended
December 31, 1997.
 
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 has not
included potential common stock in the calculation of EPS since inception as
such inclusion would have an anti-dilutive effect.
 
USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the

2. PURCHASE OF CERTAIN ASSETS FROM BECKEMEYER DEVELOPMENT TECHNOLOGIES
 
    In order to recruit the principal shareholder of Beckemeyer Development
Technologies ("BDT") to serve as the Company's Vice President of Engineering, on
November 7, 1995, the Company agreed to purchase all fixtures, equipment, and
the client list of BDT for cash of $64,000. In addition to the above, the
principal shareholder was issued warrants to purchase 10,330 shares of the
Company's Common Stock at $4.84 per share as consideration for an agreement not
to compete for a two-year period. The value assigned to the warrants was $5,000
based upon an appraisal obtained by the Company. The warrants expire October 10,
2005. This purchase price was allocated to the assets acquired with the
remainder reflected as an intangible asset. At the time of purchase, BDT was not
material to the results of operations, financial position or customer base of
EarthLink.
 
3. PURCHASE OF CERTAIN ASSETS FROM INTERNET IN A MALL
 
    In April 1997, the Company purchased the subscribers and related assets,
including accounts receivable related to the consumer dial-up Internet access
service of Internet in a Mall, a Tarzana, California based Internet access
provider. Under the terms of the agreement, as amended, the Company purchased

9. STOCK OPTIONS AND WARRANTS
 
STOCK OPTIONS
 
    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 up to 1,250,000 shares of common stock to employees of
the Company and non-qualified stock options to employees, officers, directors
and consultants of the Company. The 1995 Plan is administered by a committee
appointed by the Board 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 vest in equal quarterly increments over a five year period. As of
December 31, 1997, 87,432 options remain available for issuance under the 1995
Incentive Stock Option 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 62,500 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 10,000 and 2,500 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 vest in equal
quarterly increments over a five year period. As of December 31, 1997, there
were no outstanding options to purchase shares of Common Stock outstanding 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.
 
VALUE OF OPTIONS GRANTED TO EMPLOYEES
 
    For disclosure purposes the fair value of all stock options granted is
estimated using the Black-Scholes option-pricing model with the following
weighted average assumptions used for stock options granted in 1997: no annual
dividends, expected volatility of 69%, risk-free interest rate of 6.49%, and
expected life of 6.6 years. For 1995 and 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.

10. INCOME TAXES
 
    The stockholders, upon incorporating the Company, elected to treat the
Company as an S Corporation under the Internal Revenue Code. On June 19, 1995,
this election was revoked as certain ineligible entities (i.e partnerships and
corporations) became stockholders. Losses of $1,261,000 incurred from inception
through June 19, 1995 have been reclassified from accumulated deficit to Common
Stock as a result of the change to C Corporation status. The Company is now
subject to income taxes on income earned after June 19, 1995. At December 31,
1996 and 1997, the Company had net operating loss carryforwards for federal
income tax purposes totaling approximately $33,751,000, and $61,004,000,
respectively, which begin to expire in 2011. 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.
 
    Deferred tax assets include the following:

participants may contribute a percentage of compensation, but not in excess of
the maximum allowed under the Code. The Company makes a discretionary matching
contribution of 25% up to a maximum of 6% of the participant's total eligible
compensation. The Company's matching contributions vest over four years from the
participant's date of hire. Total contributions for 1997 were $84,000.

    During the three years ended December 31, 1997, the Company financed the
acquisition of data processing and office equipment amounting to approximately
$556,000, $11.3 million and $10.5 million, respectively, by entering into a
number of 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.
 
    Minimum lease commitments under non-cancelable leases at December 31, 1997
are as follows:

GUARANTEED USAGE LEVELS
 
    At December 31, 1997, the Company has committed to guaranteed usage levels
of data and voice communication with certain telecommunication vendors in the
aggregate amount of $3 million in 1998.
 
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
a discount, and providing access to EarthLink's member base at EarthLink's
normal rates. Payment to UUNET and PSINet is generally concurrent with
EarthLink's receipt of funds from members. At December 31, 1997, $2.0 million
and $2.1 million in amounts due to UUNET were recorded in accounts payable and
other accrued liabilities, respectively, and $540,000 and $4.4 million in
amounts due PSINet were recorded in other accrued liabilities and notes payable,
respectively.
 
    Effective June 30, 1997 the Company's agreement with UUNET was amended.
UUNET agreed to waive monthly revenue minimums, excess hours fees, and peak
service user targets during the six months ended December 31, 1997. In return,
EarthLink agreed not to invoke its early termination right prior to

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
11. COMMITMENTS AND CONTINGENCIES (CONTINUED)
 
September 1998. If the number of hours used by EarthLink members accessing the
Internet through UUNET increases beyond the amount provided for in the agreement
or the usage becomes more concentrated during peak times, the fees paid by the
Company to UUNET would increase, which would adversely affect the Company's
operating margins.
 
    EarthLink has licensed Netscape Communicator software ("Netscape
Communicator") from Netscape Communications Corporation, and Microsoft Internet
Explorer software ("Internet Explorer") from Microsoft Corporation. These
licenses permit the Company to distribute Netscape Communicator and Internet
Explorer in the EarthLink Network TotalAccess software package. Management
believes that contract renewal for both of the browsers, under conditions
acceptable to EarthLink, is probable.
 
    Minimum commitments under non-cancelable network service agreements from
UUNET and PSINet are as follows:

13. SUBSEQUENT EVENTS
 
STRATEGIC ALLIANCE WITH SPRINT CORPORATION
 
    On February 11, 1998, the Company announced a long-term strategic alliance
with Sprint Corporation. In connection with this alliance, Sprint has tendered
to purchase approximately 1.25 million shares of EarthLink's Common Stock at $45
per share. Upon closing of this tender offer, Sprint will purchase
approximately, 4.1 million shares of convertible preferred stock from Dolphin,
Inc. ("Newco") a new corporation formed by EarthLink for the purpose of
consummating the Sprint transactions. In exchange for the convertible preferred
stock Sprint will transfer its Sprint Internet Passport customer base of
approximately 130,000 members, pay approximately $24 million in cash, and
provide access to $100 million in convertible debt financing. Sprint and
EarthLink will also enter into a marketing and distribution arrangement and
EarthLink will obtain access to Sprint's data network. Concurrently with the
closing of these transactions, a wholly-owned subsidiary of Newco will merge
with and into EarthLink and each share of EarthLink Common Stock outstanding
will convert into one share of Newco common stock. Sprint will also secure two
seats on Newco's board of directors.
 
CONVERSION OF NOTE PAYABLE (UNAUDITED)
 
    On March 31, 1998, UUNET converted the $5 million Convertible Note and
related accrued interest into 391,515 shares of the Company's common stock at a
conversion price of $12.88 per share.

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-4 of Dolphin, Inc. for

expenses described in the note to the statement of revenues and expenses for the

SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES
 
BASIS OF PRESENTATION
 
    The statement of revenues and direct expenses represents the activities
related to the Consumer Internet Access Services of Sprint Corporation and has
been prepared in connection with the pending transaction between EarthLink
Network, Inc. and Sprint Corporation. The statement of revenues and direct
expenses is 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 pending 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 statement of revenues and direct expenses is 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.
 
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 was $723,000.
 
DEPRECIATION
 
    The cost of property, plant and equipment is depreciated on a straight-line
basis over estimated economic useful lives.
 
USE OF ESTIMATES
 
    The statement of revenues and direct expenses is prepared in accordance with
generally accepted accounting principles which requires management to make
estimates and assumptions that affect the amounts reported in the financial
statement. Actual results could differ from those estimates.

     (b)  On the date of commencement of the Offer, Sprint shall file with the
SEC a Tender Offer Statement on Schedule 14D-1 with respect to the Offer, which

Parties agrees promptly to correct any information provided by it for use in the
Offer Documents if and to the extent that such information shall have become
false or misleading in any material respect, and Sprint further agrees to take
all steps necessary to amend or supplement the Offer Documents and to cause the

     to do business and is in good standing in each jurisdiction in which the
     nature of its business or the ownership or leasing of its properties makes
     such qualification or licensing necessary, other than in such jurisdictions
     where the failure to be so qualified or licensed (individually or in the
     aggregate) would not have a Material Adverse Effect on the Company.  The
     Company has made available to Sprint for its review complete and correct
     copies of its certificate of incorporation and bylaws, in each case as
     amended to the date of this Agreement.

          (b)  Subsidiaries and Joint Ventures. The Company does not have any

     other than (i) liabilities provided for in the Company's unaudited balance
     sheet included in the Company's Quarterly Report on Form 10-Q for its third

     having individually or in the aggregate, a Material Adverse Effect on the
     Company, and (ii) the Company has not taken any action that would have been
     prohibited under Section 4.01 hereof as if the Agreement had been in effect
     on the date of such action.

     Documents or as set forth on Schedule 3.01(g), there is no suit, action or
     proceeding pending or, to the Knowledge of the Company, Threatened against

     Adverse Effect on the Company.

          the Code, or any other applicable Law, except liability for benefit
          claims and funding obligations or contributions payable in the
          ordinary course, and to the Company's Knowledge each of the Benefit
          Plans has at all times in all material respects been in compliance
          with and administered in accordance with its terms, the applicable
          provisions of ERISA, the Code or any other applicable Law.

          intended to be qualified in form under Section 401(a) and tax exempt
          under Section 501(a) of the Code, respectively, has been determined by
          the IRS to so qualify under the Code and, to the Company's Knowledge,
          nothing has occurred since such determination to cause any of such
          Benefit Plans not to qualify under Section 401(a) or any of such
          related trusts not to be tax exempt under Section 501(a) of the Code
          other than the effective date of certain amendments of the Code and
          ERISA, the remedial amendment period for which has not expired.

          or Section 4975 of the Code involving the Company, and there is no
          action, suit, grievance, arbitration or other claim with respect to
          the administration or investment of assets of the Benefit Plans (other
          than routine claims for benefits made in the ordinary course) pending,
          or to the Company's Knowledge, Threatened, and to the Company's
          Knowledge there is no present condition or set of circumstances which
          could reasonably be expected to give rise to any such action, suit,
          grievance, arbitration or other claim.

               (vi)   Neither the Company nor any corporation, trade or business
          which is affiliated with the Company, in the manner described in

     and accurate except where the failure to be complete or accurate would not
     have a Material Adverse Effect on the Company.  The Company has paid or has
     set up an adequate reserve for the payment of all Taxes shown as due on
     such Returns, except where the failure to do so would not have a Material
     Adverse Effect on the Company.  The Unaudited Balance Sheet contains an

     Except as set forth on Schedule 3.01(n), none of the Intellectual Property
     Assets owned or licensed by the Company infringes, or conflicts with, or to
     the Company's Knowledge, is alleged to infringe upon or conflict with the
     intellectual property rights of any third party, which infringement or
     alleged infringement could have a Material Adverse Effect. The Company has
     no Knowledge that any of its employees performing or managing key functions
     of the Company is obligated under any contract (including licenses,
     covenants or commitments of any nature) or other agreement, or subject to
     any judgment, decree or order of any court or administrative agency, that
     would interfere with the use of such employee's best efforts to promote the
     interests of the Company or that would conflict with the Company's business
     as proposed to be conducted. To the Company's Knowledge, neither the
     execution nor delivery of this Agreement or any Ancillary Agreement, nor
     the conduct of the Company's business by the employees of the Company, nor
     the conduct of the Company's business as proposed, will conflict with or
     result in a breach of the terms, conditions or provisions of, or constitute
     a default under, any contract, covenant or instrument under which any of
     such employees is now obligated, which conflict or breach would have a
     Material Adverse Effect. The Company does not presently utilize or intend
     to utilize any inventions of any of its employees (or people it currently
     intends to hire) made prior to their employment by the Company. To the
     Company's Knowledge, any software owned by the Company, and any software
     used independently by the Company and owned by third parties and licensed
     to the Company is, in all material respects, Year 2000 Compliant. "Year
     2000 Compliant" means (i) the software is capable of correctly processing,
     providing and receiving date data within and between the twentieth and
     twenty-first century (including accounting for all required leap year
     calculations); and (ii) all date fields in the software use four digit year
     fields.

          (o) Certain Payments. Neither the Company, nor any of its directors,
     officers, agents, or employees, or to the Company's Knowledge, any other
     Person associated with or acting for or on behalf of the Company, has
     directly or indirectly (a) made any contribution, gift, bribe, rebate,
     payoff, influence payment, kickback, or other payment to any Person,
     private or public, regardless of form, whether in money, property, or
     services (i) to obtain favorable treatment in securing business, (ii) to
     pay for favorable treatment for business secured, (iii) to obtain special
     concessions or for special concessions already obtained, for or in respect
     of the Company or any Affiliate of the Company, (b) established or
     maintained any fund or asset that has not been appropriately recorded in
     the books and records of the Company, which in the case of either clause
     (a) or (b) would be in violation of Law or would have a Material Adverse
     Effect.

     Company) and $10 in cash received by Newco Sub for the issuance of 10
     shares of its common stock to Newco, which in each case represents all of
     their outstanding shares of capital stock) or is a party to any agreement,
     except for this Agreement. Each of Newco and Newco Sub is a corporation

     the Merger, be duly qualified or licensed to do business and be in good
     standing in each jurisdiction in which the nature of the business conducted
     or the ownership or leasing of its properties makes such qualification or
     licensing necessary, other than in such jurisdictions where the failure to
     be so qualified or licensed (individually or in the aggregate) would not
     have a Material Adverse Effect on Newco immediately following the Merger.
     Each of Newco and Newco Sub has made available to Sprint for its review
     complete and correct copies of its certificate of incorporation and bylaws,
     in each case as amended to the date of this Agreement.

     and Newco Sub in accordance with the DGCL, to consummate the transactions
     contemplated by this Agreement and the Ancillary Agreements. Except as set
     forth on Schedule 3.02(b), the execution and delivery by each of Newco and

     party and the consummation by each of them of the transactions contemplated
     by this Agreement and the Ancillary Agreements have been duly authorized by
     all necessary corporate action on the part of Newco and Newco Sub,
     respectively, subject, with respect to consummation of the Merger, to prior
     approval of the Merger by the stockholders of the Company, Newco and Newco
     Sub in accordance with DGCL. This Agreement and the Ancillary Agreements to

     and the Company, constitute valid and binding obligations of each of them
     enforceable against Newco and Newco Sub, respectively, in accordance with
     their respective terms, except to the extent that the enforcement hereof
     and thereof may be limited by (i) bankruptcy, insolvency, reorganization,
     moratorium or other similar laws now or hereafter in effect relating to
     creditors' rights generally, and (ii) general principles of equity
     regardless of whether enforceability is considered in a proceeding in
     equity or at law. Except as set forth on Schedule 3.02(b), the execution

     without obtaining the consent of any third party will not, conflict with,
     or result in any violation of, or default (with or without notice or lapse
     of time, or both) under, or give rise to a right of termination,
     cancellation or acceleration of any obligation or to loss by Newco or Newco
     Sub of a material benefit under, or result in the creation of any Lien upon

     other matters referred to in the following sentence, any Law applicable to
     Newco or Newco Sub or their respective assets, other than, in the case of
     clauses (ii) and (iii), any such conflicts, violations, defaults, rights or
     Liens that individually or in the aggregate would not (x) have a Material
     Adverse Effect on Newco or Newco Sub, (y) materially impair the ability of
     Newco and Newco Sub to perform its obligations under this Agreement or any
     Ancillary Agreement to which it is a party or (z) prevent the consummation

     the Knowledge of Newco or Newco Sub, Threatened against Newco or Newco Sub.

          (d)  Voting Requirements. The only vote of the holders of any class or
     series of the capital stock of Newco and Newco Sub that is necessary to
     approve this Agreement, the Ancillary Agreements or the transactions
     contemplated by this Agreement and the Ancillary Agreements is the
     affirmative vote by the holders of a majority of their respective
     outstanding shares of common stock entitled to vote with respect to the
     Merger, as required by Section 251 of the DGCL.

          (e)  Brokers. No broker, investment banker, financial advisor or other
     person, other than Deutsche Morgan Grenfell Inc., the fees and expenses of
     which will be paid by the Company, is entitled to any broker's, finder's,

     the transactions contemplated by this Agreement and the Ancillary
     Agreements based upon arrangements made by or on behalf of Newco and Newco
     Sub.

     following the Merger, have all Permits necessary for them to own, lease or
     operate the properties and assets now owned by the Company and to carry on
     the business now conducted by the

                                       26
<PAGE>
 
     Company, except for such Permits, the absence of which would not have,
     individually or in the aggregate, a Material Adverse Effect on Newco and
     Newco Sub, taken as a whole.

     SECTION 3.03   Representations and Warranties of Sprint and Sprint L.P..
Sprint and Sprint L.P., jointly and severally, represent and warrant to the
Company, Newco and Newco Sub as follows:

          (a)  Organization, Standing and Power. Sprint is a corporation duly
     organized, validly existing and in good standing under the laws of the
     jurisdiction in which it is incorporated. Sprint L.P. is a limited
     partnership duly organized, validly existing and in good standing under the
     laws of the jurisdiction in which it is organized. Each of Sprint and
     Sprint L.P. has all requisite power and authority to own, lease and operate
     their respective properties and to carry on their respective businesses as
     now being conducted. Each of Sprint and Sprint L.P. and each of their
     respective Significant Subsidiaries is duly qualified or licensed to do
     business and is in good standing in each jurisdiction in which the nature
     of its business or the ownership or leasing of its properties makes such
     qualification or licensing necessary, other than in such jurisdictions
     where the failure to be so qualified or licensed (individually or in the
     aggregate) could not reasonably be expected to have a Material Adverse
     Effect on Sprint or Sprint L.P. and their respective Subsidiaries, taken as
     a whole. Sprint has made available to the Company, Newco and Newco Sub for
     their review complete and correct copies of its certificate of
     incorporation and bylaws. Sprint L.P. has made available to the Company,
     Newco and Newco Sub for their review a complete and correct copy of its
     constitutive documents.

          (b)  Subsidiaries. A schedule to Sprint's Annual Report on Form 10-K
     for 1996 lists each Significant Subsidiary of Sprint. All the outstanding
     shares of capital stock of each Significant Subsidiary that is a
     corporation have been validly issued and are fully paid and nonassessable
     and are not subject to any options or other rights to acquire any such
     shares.

          (c)  Authority; Noncontravention. Sprint has the requisite corporate
     power and authority, and Sprint L.P. has the requisite power and authority,
     to enter into this Agreement and the Ancillary Agreements and to consummate
     the transactions contemplated by this Agreement and the Ancillary

     Agreement and each Ancillary Agreement to which it is a party and the
     consummation by it of the transactions contemplated by this Agreement and
     the Ancillary Agreements have been duly authorized by, in the case of
     Sprint, all necessary corporate action, and in the case of Sprint L.P., all
     necessary action of the limited partnership and its general partner. This
     Agreement and the Ancillary Agreements to which Sprint or Sprint L.P. is
     party have been duly executed and delivered by Sprint and Sprint L.P. and,
     assuming this Agreement and the Ancillary Agreements constitute the valid
     and binding agreements of the Company, Newco and Newco Sub, constitute
     valid and binding obligations enforceable against Sprint and Sprint L.P. in
     accordance with their respective terms, except to the extent

                                       27
<PAGE>
 
     that the enforcement of this Agreement or the Ancillary Agreements may be
     limited by (i) bankruptcy, insolvency, reorganization, moratorium or other
     similar laws now or hereafter in effect relating to creditors' rights
     generally, and (ii) general principles of equity regardless of whether
     enforceability is considered in a proceeding in equity or at law. Except as
     set forth on Schedule 3.03(c), the execution and delivery of this Agreement
     and the Ancillary Agreements by Sprint and Sprint L.P. did not, and the
     consummation of the transactions contemplated by this Agreement and the

     Agreement and the Network Agreement without obtaining the consent of any
     third party will not, conflict with, or result in any violation of, or

     rise to a right of termination, cancellation or acceleration of any
     obligation or to loss by Sprint, Sprint L.P. or any of Sprint's Significant
     Subsidiaries, of a material benefit under, or result in the creation of any
     Lien upon any of the properties or assets of Sprint or Sprint L.P. under,
     (i) the certificate of incorporation or bylaws of Sprint or the comparable
     charter or organizational documents of Sprint L.P. or any of Sprint's
     Significant Subsidiaries, (ii) any loan or credit agreement, note, bond,
     mortgage, indenture, lease or other agreement, instrument, permit or
     license applicable to Sprint, Sprint L.P. or any of Sprint's Significant
     Subsidiaries or their respective properties or assets or (iii) subject to
     the governmental filings and other matters referred to in the following
     sentence, any judgment, order, decree, statute, law, ordinance, rule or
     regulation applicable to Sprint, Sprint L.P. or any of Sprint's Significant
     Subsidiaries or their respective properties or assets, other than, in the
     case of clauses (ii) and (iii), any such conflicts, violations, defaults,
     rights or Liens that individually or in the aggregate would not (x) have a
     Material Adverse Effect on Sprint, Sprint L.P. and Sprint's Subsidiaries,
     taken as a whole, (y) materially impair the ability of Sprint or Sprint
     L.P. to perform their respective obligations under this Agreement or any
     Ancillary Agreement to which it is a party or (z) prevent the consummation

     Ancillary Agreements. No consent, approval, order or authorization of, or
     registration, declaration or filing with, any Governmental Entity is
     required by or with respect to Sprint or Sprint L.P. or any of Sprint's
     Significant Subsidiaries in connection with the execution and delivery of
     this Agreement and the Ancillary Agreements or the consummation by Sprint
     or Sprint L.P. of the transactions contemplated by this Agreement and the
     Ancillary Agreements, except for (i) the filing of a premerger notification
     and report form by Sprint or Sprint L.P. under the HSR Act and the
     expiration of the applicable waiting period or early termination thereof
     and, (ii) the filing with the SEC of (x) a tender offer statement on
     Schedule 14D-1 and (y) such reports under Sections 12 and 13(a) of the
     Exchange Act as may be required in connection with this Agreement, the
     Ancillary Agreements and the transactions contemplated by this Agreement
     and the Ancillary Agreements, and (iii) such other consents, approvals,
     orders, authorizations, registrations, declarations and filings as are set

          (d)  Brokers. No broker, investment banker, financial advisor or other
     person, other than SBC Warburg Dillon Read, Inc. the fees and expenses of
     which will be paid by Sprint, is entitled to any broker's, finder's,
     financial advisor's or other similar fee or

                                       28

     commission in connection with the transactions contemplated by this
     Agreement and the Ancillary Agreements based upon arrangements made by or
     on behalf of Sprint or Sprint L.P.

          (e)  Ownership of Common Stock. As of the date of this Agreement,
     neither Sprint nor Sprint L.P. beneficially owns any shares of Common
     Stock.

          (f)  Investment Intent. Sprint is purchasing the Convertible Notes for
     advances under the Credit Agreement, and Sprint L.P. is purchasing the
     Convertible Preferred Stock in exchange for the Preferred Stock
     Consideration, in each case for their own account for investment and not
     with a present view to, or for sale in connection with, any distribution
     thereof in violation of the Securities Act. The certificates evidencing the
     Convertible Preferred Stock, the Convertible Notes and any shares of Common
     Stock issued upon conversion of the Convertible Preferred Stock or the
     Convertible Notes shall bear substantially the following legend (modified
     accordingly in the case of the Convertible Notes) until such time as there
     is a sale or transfer in accordance with this Agreement and the Ancillary
     Agreements or the termination thereof:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
          ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
          CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. THE
          DISPOSITION AND VOTING OF SUCH SHARES IS SUBJECT TO THE
          CONDITIONS SPECIFIED IN THE INVESTMENT AGREEMENT DATED AS OF
          FEBRUARY 10, 1998, AMONG THE COMPANY, SPRINT, SPRINT L.P.,
          NEWCO, AND NEWCO SUB AND THE GOVERNANCE AGREEMENT DATED AS
          OF FEBRUARY 10, 1998, AMONG THE COMPANY, SPRINT, SPRINT
          L.P., AND NEWCO, AND NEWCO RESERVES THE RIGHT TO REFUSE THE
          TRANSFER OF SUCH SHARES UNTIL SUCH CONDITIONS HAVE BEEN
          FULFILLED WITH RESPECT TO SUCH TRANSFER. A COPY OF SUCH
          CONDITIONS WILL BE FURNISHED BY NEWCO TO THE HOLDER HEREOF
          UPON WRITTEN REQUEST AND WITHOUT CHARGE. THESE SECURITIES
          HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED
          OR HYPOTHECATED EXCEPT IN ACCORDANCE THEREWITH."

          (g)  Acquisition for Investment and Rule 144. Sprint and Sprint L.P.
     understand that the shares of Convertible Preferred Stock issued to them
     pursuant to the Agreement ("Sprint Shares") and Sprint understands that the
     Convertible Notes issued to Sprint pursuant to the Credit Agreement will
     not be registered under the Securities Act by reason of a specific
     exemption from the registration provision of the Securities Act which
     depends upon, among other things, the bona fide nature of their investment
     intent as expressed herein. Except as otherwise provided in Section
     3.03(i), Sprint and Sprint L.P. acknowledge that the Sprint Shares and the
     Convertible Notes must be held indefinitely unless they are subsequently

                                       29
<PAGE>
 
     registered under the Securities Act or an exemption from such registration
     is available. Sprint and Sprint L.P. have been advised or are aware of the
     provisions of Rule 144 promulgated under the Securities Act which permit
     limited resale of shares purchased in a private placement subject to the
     satisfaction of certain conditions. Sprint and Sprint L.P. are aware that
     the certificates representing the Sprint Shares, and that the Convertible
     Notes, will bear such legends relating to restrictions on resale under the
     Securities Act as provided in Section 3.01(f) and Newco under certain
     conditions may issue instructions to its stock transfer agent to stop the
     transfer of the Sprint Shares and the Convertible Notes unless made in
     accordance with this Agreement or any Ancillary Agreement.

          (h)  Legal Investment. The purchase of the Convertible Preferred Stock
     by Sprint L.P. and the purchase of Convertible Notes by Sprint hereunder is
     legally permitted by all applicable Law and all consents, approvals,
     authorizations of or designations, declarations or filings in connection
     with the valid execution and delivery of this Agreement by Sprint and
     Sprint L.P. or the purchase of the Convertible Preferred Stock by Sprint
     L.P. and the Convertible Notes by Sprint have been obtained, or will be
     obtained prior to the Closing Date.

          (i)  Purchase Entirely for Own Account. Sprint is purchasing the
     Convertible Notes for advances under the Credit Agreement, and Sprint L.P.
     is purchasing the Convertible Preferred Stock in exchange for the Preferred
     Stock Consideration, in each case for their own account and not as a
     nominee or agent, and not with a view to the resale or distribution of any
     part thereof, except for transfers permitted by this Agreement. Neither
     Sprint L.P. nor Sprint has any present intention of selling, granting any
     participation in, or otherwise distributing the Convertible Preferred Stock
     or the Convertible Notes. Neither Sprint nor Sprint L.P. has any contract,
     undertaking, agreement or arrangement with any Person to sell, transfer or
     grant participations to such Person or to any third person with respect to
     the Convertible Preferred Stock or the Convertible Notes. Notwithstanding
     any other provision of this Agreement, Sprint and Sprint L.P. shall be
     permitted to transfer the Convertible Preferred Stock, the Convertible
     Notes and the Newco Common Stock issued upon conversion thereof to any
     Affiliate of Sprint or Sprint L.P. without an opinion of counsel, without
     registration under the Securities Act or any state securities law, and
     without the consent of Newco, provided that any such Affiliate who acquires
                                   --------
     such Convertible Preferred Stock, Convertible Notes or Newco Common Stock
     agrees in writing to be subject to the applicable requirements of this
     Section 3.03 and any restrictions on transfer contained in any of the
     Ancillary Agreements to the same extent as if such Affiliate were the
     original purchaser thereof.

          (j)  Agreements with SIP Subscribers. Sprint L.P. has previously
     furnished to each of the Company, Newco and Newco Sub the form of agreement
     between Sprint L.P. and the SIP Subscribers governing the receipt of
     internet access services from Sprint L.P. ("SIP Agreements"). Sprint L.P.
     has complied in all material respects with all applicable terms and
     requirements of the SIP Agreements. As of the date hereof, Sprint has
     approximately 130,000 SIP Subscribers who are subject to SIP Agreements.
     Except as set forth in Schedule 3.03(j), the SIP Agreements are assignable
     to Newco in accordance with this Agreement and are enforceable against
     Sprint L.P. in accordance with their respective terms, except to the

                                       30
<PAGE>
 
     extent enforcement thereof may be limited by: (i) bankruptcy, insolvency,
     reorganization, moratorium or other similar laws now or hereafter in effect
     relating to creditors' rights generally, and (ii) general principals of
     equity, regardless of whether enforceability is considered in a proceeding
     in equity or at law; provided, however, that the SIP Agreements are subject
                          --------  -------    
     to immediate termination by unilateral action of the SIP Subscribers.

          (k) Financial Capability.  Sprint has sufficient funds available to
     finance the Offer and the other transactions contemplated by this Agreement
     and the Ancillary Agreements, and is not engaged in any financing activity,
     the consummation of which would be necessary in order for Sprint to
     consummate the Offer and the other transactions contemplated by this
     Agreement and the Ancillary Agreements.

Ancillary Agreements or

                                       34

acquire solely the same respective number of shares of Newco Common Stock after
the Merger.

(iv) any plan, agreement, arrangement or understanding pursuant to which any
termination or severance pay or other compensation of any officer, director or
employee of the Company is or may become due, in order, in any such case, to
ensure that none of the transactions contemplated by this Agreement or any of
the Ancillary Agreements (including, without limitation, conversion of the
Convertible Preferred Stock and/or the Convertible Notes) will, constitute a
"change of control," or any similar event or occurrence within the meaning of
any such term or any similar term contained in any of the foregoing, or
otherwise cause or result in the acceleration of the vesting of such options or
rights or of the time at which such options or rights are permitted to be
exercised, or the acceleration of the right to receive termination or severance
pay or other compensation, in any such case either alone or together with any
other event or occurrence, such as the termination or constructive termination

agreement with Newco on their own initiative); provided, however, that such
                                               --------  -------           
customers may be serviced by the Company pursuant to an agreement to do so
containing terms and conditions as would be obtained by Persons dealing at arms
length.  During the period commencing on the Closing Date and continuing until
the 31st day after the Closing Date, Newco shall not (i) discontinue or modify,
or publicly announce the discontinuance or modification, of the current $5.00
credit program (i.e., whereby SIP Subscribers are entitled to a $5.00 credit

program), or (ii) make any change or modification to any other term or condition
of the SIP Agreement which is reasonably likely to result in a reduction in the
number of SIP Subscribers within the aforementioned time period.

     paid on the date of receipt of payment or upon which the subscriber's
     credit card is billed by Sprint L.P., the Company or Newco, as the case may
     be.

          (b)  On or before the 45th day following the Closing Date, Newco shall
     prepare and deliver to Sprint L.P. a schedule (the "SIP True-Up
     Certificate") certified by its chief financial officer showing (i) the
     number and identity of the SIP Subscribers who have paid pursuant to SIP
     Agreements at any time on or prior to the 31st day after the Closing Date
     ("Paid SIP Subscribers") and (ii) the number and identity of the SIP
     Subscribers who have not paid pursuant to SIP Agreements at any time on

     requested to verify the matters covered by the SIP True-Up Certificate,
     with such mutually agreed upon number of Paid SIP Subscribers referred to
     as the "Final Number of Paid SIP Subscribers."

          (c)  If the Final Number of Paid SIP Subscribers is less than 130,000,
     then Sprint L.P. shall forfeit to Newco a number of shares of Convertible
     Preferred Stock equal to the product of (i) five shares of Convertible
     Preferred Stock, times (ii) 130,000 minus the Final Number of Paid SIP
     Subscribers, with such product referred to as the "Number of Forfeited
     Shares of Convertible Preferred Stock."  Sprint L.P. shall deliver to Newco
     the stock certificate evidencing its shares of Convertible Preferred Stock
     originally issued to it on the Closing Date (the "Number of Original Shares
     of Convertible Preferred Stock"), together with duly executed stock power
     transferring to Newco the Number of Forfeited Shares of Convertible
     Preferred Stock and Newco shall thereupon issue to Sprint L.P. a balance
     certificate evidencing a number of shares of Convertible Preferred Stock
     equal to the difference between the Number of Original Shares of
     Convertible Preferred Stock and the Number of Forfeited Shares of
     Convertible Preferred Stock.

terms or provisions of this Agreement or the Ancillary Agreements or under any
other circumstances, and the parties shall negotiate in good faith a substitute
provision which comes as close as possible to the invalidated or unenforceable

         3.       Dividend Provisions.

                  (a)      Dividends.

                           (i) Mandatory PIK Dividends. On and before the fifth
                  anniversary of the Purchase Date, the Corporation shall pay,
                  and the holders of outstanding shares of Series A Preferred
                  Stock ("Holders") shall be entitled to receive on each
                  Dividend Payment Date, a dividend on each share of Series A
                  Preferred Stock at a rate per annum equal to three percent
                  (3.00%) of the Liquidation Value (as then increased, as
                  provided in Section 4(a)) per share of Series A Preferred
                  Stock, accruable and compounded quarterly on each of the
                  Dividend Accrual Dates, which dividend shall be in the form of
                  an increase in the Liquidation Value in such amount (each such
                  increase is referred to as a "Liquidation Accretion
                  Dividend"). All dividends shall accrue quarterly in arrears
                  and shall compound on each Dividend Accrual Date, commencing
                  on the first Dividend Accrual Date after the date of issuance
                  of the applicable shares of Series A Preferred Stock. The
                  Board of Directors shall declare and pay such accrued
                  dividends on each Dividend Payment Date and the Corporation
                  shall take all further actions necessary to cause such
                  dividend to be paid to the Holders in the form and manner
                  prescribed herein. Notwithstanding the foregoing, upon the
                  first date of the consummation of a Business Combination, or
                  an Optional Redemption by the Corporation pursuant to Section
                  6(a), the Corporation shall pay, and the Holders of
                  outstanding shares of Series A Preferred Stock shall be
                  entitled to receive, a dividend on each share of Series A
                  Preferred Stock in the form of an aggregate increase in the
                  Liquidation Value in an amount equal to the amount by which
                  the Liquidation Value would have increased pursuant to this
                  Section 3(a)(i) if such Holder had held such shares of Series
                  A Preferred Stock, until the first Dividend Payment Date on or
                  following the fifth anniversary of the Purchase Date.

                           (ii) Cash Dividends. After the fifth anniversary of
                  the Purchase Date, the Corporation shall pay, and the Holders
                  of outstanding shares of Series A Preferred Stock shall be
                  entitled to receive, when, as and if declared by the Board of
                  Directors, out of funds legally available therefor, cumulative
                  dividends on each share of Series A Preferred Stock at a rate
                  per annum equal to three percent (3.00%) of the Liquidation
                  Value per share of Series A Preferred Stock, accruable
                  quarterly on each of the Dividend Accrual Dates, payable only
                  in cash; provided, however, that after the twentieth
                  anniversary of the Purchase Date, the Corporation shall pay,
                  and the Holders of outstanding shares of Series A Preferred
                  Stock shall be entitled to receive, when, as and if declared
                  by the Board of Directors, out of funds legally available
                  therefor, cumulative dividends on each share of Series A
                  Preferred Stock at a rate per annum equal to 8% of the
                  Liquidation Value per share of Series A Preferred Stock,
                  accruable quarterly on each of the Dividend Accrual Dates,
                  payable only in cash, which rate shall increase by 200 basis
                  points on each anniversary of the Closing Date thereafter, but
                  not to exceed a maximum rate of 12%. All cash dividends shall
                  be


                                       2
<PAGE>

                  cumulative, whether or not declared, on a daily basis from the
                  fifth anniversary of the Purchase Date or the date of
                  issuance, whichever is later, and shall accrue quarterly in
                  arrears on each Dividend Accrual Date, commencing on the first
                  Dividend Accrual Date after the fifth anniversary of the
                  Purchase Date or the date of issuance, whichever is later. The
                  Board of Directors shall declare and pay such accrued
                  dividends at such time and to the extent permitted by law.

                           (iii) General Provisions. Each distribution in the
                  form of a cash dividend shall be payable to Holders of record
                  as they appear on the stock books of the Corporation on such
                  record date, not less than 10 nor more than 60 days preceding
                  the relevant Dividend Payment Date, as shall be fixed by the
                  Board of Directors of the Corporation. For any period during
                  which any share of Series A Preferred Stock is outstanding
                  less than a full quarterly dividend period ending on a
                  Dividend Accrual Date, the dividends payable shall be computed
                  on the basis of a 360 day year consisting of twelve 30-day
                  months and the actual number of days elapsed in the period for
                  which the dividends are payable. If any Dividend Payment Date
                  for a dividend payable in cash occurs on a day that is not a
                  Business Day, any accrued dividends otherwise payable on such
                  Dividend Payment Date shall be paid on the next succeeding
                  Business Day.

                  (b) Certain Other Non-Cash Distributions. If the Corporation
         shall at any time, or from time to time, after the Purchase Date,
         declare, order, pay or make a dividend or other distribution
         (including, without limitation, any distribution or issuance of stock
         or other securities or property or rights or warrants to subscribe for
         securities of the Corporation or any of its Subsidiaries by way of
         dividend or spinoff or rights to purchase Common Stock or other Junior
         Securities) on its Common Stock, other than (i) dividends payable in
         cash in an aggregate amount in any fiscal year which, when declared,
         are not expected to exceed the net income of the Corporation during
         such year from continuing operations before extraordinary items, as
         determined in accordance with generally accepted accounting principles
         consistently applied in accordance with past practice, or (ii) any
         dividend or distribution described in Section 5(c)(i), Section 5(c)(ii)
         or Section 5(c)(iii), then, and in each such case (a "Triggering
         Distribution"), each Holder of shares of Series A Preferred Stock shall
         be entitled to receive from the Corporation, with respect to the shares
         of Series A Preferred Stock held by such Holder, the same dividend or
         distribution that such Holder would have received if immediately prior
         to the earlier of such Triggering Distribution or any record date
         therefor (i) a Business Combination had occurred causing the last
         sentence of Section 3(a)(i) to be effected, and (ii) such Holder
         converted all of such Holder's shares of Series A Preferred Stock into
         shares of Common Stock. Any such dividend, distribution or issuance
         shall be declared, ordered, paid or made on the Series A Preferred
         Stock at the same time such dividend, distribution or issuance is
         declared, ordered, paid or made on the Common Stock.

                                       3
<PAGE>

                  (c) Limitation on Dividends and Other Distributions. Unless
         full cumulative dividends, if any, accrued on all outstanding shares of
         the Series A Preferred Stock have been or contemporaneously are
         declared and paid for all periods prior to and ending on the most
         recent Dividend Accrual Date, no dividend shall be declared or paid or
         set aside for payment or other distribution declared or made upon the
         Junior Securities (other than a dividend or distribution paid solely in
         shares of, or warrants, rights or options solely exercisable for or
         convertible into, Junior Securities), nor shall any Junior Securities
         be redeemed, purchased or otherwise acquired for any consideration, nor
         may any moneys be paid to or made available for a sinking fund for the
         redemption of any shares of any such securities, by the Corporation
         (other than redemptions and purchases pursuant to or in accordance with
         agreements between the Corporation and its or its subsidiaries'
         directors, officers and key employees), except by conversion into or
         exchange for Junior Securities.

         4.       Liquidation Preference.

                  (a) In the event of any voluntary or involuntary liquidation,
         dissolution or winding up of the Corporation ("Liquidation Event"), the
         Holders of Series A Preferred Stock then outstanding shall be entitled
         to receive, prior and in preference to any distribution of any of the
         assets of the Corporation to the holders of Common Stock and other
         Junior Securities by reason of their ownership thereof, an amount per
         share equal to the sum of (i) the average of the Closing Price per
         share of Common Stock for the 30 Trading Days immediately preceding the
         Purchase Date (the "Average Stock Price") for each outstanding share of
         Series A Preferred Stock, (ii) the amount of all Liquidation Accretion
         Dividends that have been paid pursuant to Section 3(a)(i) (including an
         amount equal to a prorated dividend pursuant to Section 3(a)(i) for the
         period from the Dividend Accrual Date immediately preceding the date of
         the Liquidation Event through the date of the Liquidation Event), and
         (iii) all accumulations of accrued but unpaid dividends payable in cash
         pursuant to Section 3(a)(ii) on each share of Series A Preferred Stock
         (including an amount equal to a prorated dividend pursuant to Section
         3(a)(ii) for the period from the Dividend Accrual Date immediately
         prior to the receipt of such sum to the date of receipt of such sum),
         with the sum of the amounts referred to in clauses (i), (ii) and (iii)
         referred to herein as the "Liquidation Value". The schedule of (i) the
         amount of the applicable Liquidation Accretion Dividend for each Share
         of Series A Preferred Stock for each Dividend Payment Date therefor,
         and (ii) the cumulative amount of the Liquidation Value for each Share
         of Series A Preferred Stock, as of each Dividend Payment Date, is as
         follows:

         Holders of outstanding shares of Series A Preferred Stock shall share
         ratably in such distribution of assets. Except as provided in this
         Section 4(a), Holders of Series A Preferred Stock shall not be entitled
         to any additional distribution upon the occurrence of a Liquidation
         Event.

                  (b) After the distribution described in Section 4 (a) has been
         paid, the remaining assets of the Corporation available for
         distribution to shareholders shall be distributed among the holders of
         Junior Securities in accordance with their respective rights thereto.

                  (c) Neither the consolidation, merger, Business Combination or
         any other form of business combination of the Corporation with or into
         any other person or entity, nor the sale, lease, exchange, conveyance
         or disposition of all or substantially all of the assets of the
         Corporation to persons or entities other than the holders of Junior
         Securities shall be deemed to be a Liquidation Event for purposes of
         this Section 4.

         5. Conversion. The Holders of the Series A Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

                  (a)      Optional Conversion Rights and Automatic Conversion.

                           (i) Each share of Series A Preferred Stock shall be
                  convertible, at the option of the Holder thereof, at any time
                  after the first anniversary of the Purchase Date, at the
                  office of the Corporation or any transfer agent for the Series
                  A Preferred Stock, into such number of validly issued, fully
                  paid and nonassessable shares of Common Stock, free and clear
                  of all pledges, claims, liens, charges, encumbrances and
                  security interests of any kind or nature whatsoever, as is
                  determined by dividing the Liquidation Value by the Conversion
                  Price at the time in effect for such share; provided, however,
                  that, notwithstanding any other provision hereof to the
                  contrary, conversion of all outstanding shares of Series A
                  Preferred Stock shall be required in the event of consummation
                  of a Business Combination. The Conversion Price per share for
                  shares of Series A Preferred Stock shall be (i) for the period
                  from the Purchase Date through the Dividend Accrual Date
                  immediately after the fifth anniversary of the Purchase Date,
                  the product of (A) the Average Stock Price, times (B)
                  116.118%, and (ii) thereafter, the Conversion Price then in
                  effect shall be increased at a rate per annum equal to six
                  percent (6%) thereof, accruable quarterly, and in each case
                  the Conversion Price shall be subject to adjustment, from time
                  to time as set forth in Section 5(c).

                           (ii) Upon conversion of any Series A Preferred Stock,
                  payment shall be made for (A) dividends under Section 3(a)(i)
                  on each converted share of Series A Preferred Stock in an
                  amount equal to a prorated Liquidation Accretion Dividend for
                  the period from the Dividend Accrual Date immediately prior to
                  the date of conversion to such conversion date, and (B) unpaid
                  dividends under Section 3(b) resulting from events described
                  therein and occurring prior to the date of conversion.

                  (b) Mechanics of Conversion. If the Holder of shares of Series
         A Preferred Stock desires to exercise such right of conversion, such
         Holder shall give written notice to the Corporation (the "Conversion
         Notice") of that Holder's election to convert a stated whole number of
         shares of Series A Preferred Stock (the "Conversion Shares") into
         shares of Common Stock, and surrender to the Corporation, at its
         principal office or at such other office or agency maintained by the
         Corporation for such purpose, such Holder's certificate or certificates
         evidencing such Conversion Shares. The Conversion Notice shall also
         contain a statement of the name or names (with addresses) in which the
         certificate or certificates for Common Stock shall be issued.
         Notwithstanding the foregoing, the Corporation shall not be required to
         issue any certificates to any person other than the Holder thereof
         unless the Corporation has obtained reasonable assurance that such
         transaction is exempt from the registration requirements of, or is
         covered by an effective registration statement under, the Securities
         Act of 1933, as amended (the "Act"), and all applicable state
         securities laws, including, if necessary in the reasonable judgment of
         the Corporation or its legal counsel, receipt of an opinion to such
         effect from counsel reasonably satisfactory to the Corporation. In no
         event would such opinion be required if the shares of Common Stock
         could, upon conversion, be resold pursuant to Rule 144 or Rule 144A
         under the Act. As promptly as practicable, and in any event within five
         business days, after the receipt of the Conversion 


                                       6
<PAGE>

         Notice and the surrender of the certificate or certificates
         representing the Conversion Shares, the Corporation shall issue and
         deliver, or cause to be delivered, to the Holder of the Conversion
         Shares or his nominee or nominees, (i) a certificate or certificates
         for the number of shares of Common Stock issuable upon the conversion
         of such Conversion Shares and (ii) if less than the full number of
         shares of Series A Preferred Stock evidenced by the surrendered
         certificate or certificates are being converted, a new certificate or
         certificates, of like tenor, evidencing the number of shares evidenced
         by such surrendered certificate or certificates less the number of
         Conversion Shares. Such conversion shall be deemed to have been
         effected as of the close of business on the date the Corporation
         received the Conversion Notice and the certificate or certificates
         representing the Conversion Shares, and the person or persons entitled
         to receive the shares of Common Stock issuable upon conversion shall be
         treated for all purposes as the holder or holders of record of such
         shares of Common Stock as of the close of business on such date,
         provided, however, that if such conversion by a Holder of Series A
         Preferred Stock would give rise to the waiting period of the HSR Act,
         such conversion shall not be effective and shall be contingent upon (i)
         the expiration or termination of such waiting period, and (ii) the
         absence of any action taken or instituted by the Department of Justice,
         the Federal Trade Commission or any other governmental entity by the
         expiration or termination of such waiting period to delay, enjoin or
         place conditions on such conversion.

                  (c)      Conversion Price Adjustments of Preferred Stock.

                           (i) If the Corporation should at any time or from
                  time to time after the Purchase Date fix a record date for the
                  effectuation of a split or subdivision of the outstanding
                  shares of Common Stock or the determination of holders of
                  Common Stock entitled to receive a dividend or other
                  distribution payable in additional shares of Common Stock,
                  then, as of such record date (or, if no record date is fixed,
                  as of the close of business on the date on which the Board of
                  Directors adopts the resolution relating to such dividend,
                  distribution, split or subdivision), the Conversion Price
                  shall be decreased to equal the product of the Conversion
                  Price in effect immediately prior to such date multiplied by a
                  fraction, the numerator of which shall be the number of shares
                  of Common Stock outstanding immediately prior thereto and the
                  denominator of which shall be the number of shares of Common
                  Stock outstanding immediately thereafter.

                           (ii) If the number of shares of Common Stock
                  outstanding at any time or from time to time after the
                  Purchase Date is decreased by a combination of the outstanding
                  shares of Common Stock, then following such combination, the
                  Conversion Price shall be increased to equal the product of
                  the Conversion Price in effect immediately prior thereto
                  multiplied by a fraction, the numerator of which shall be the
                  number of shares of Common Stock outstanding immediately prior
                  thereto and the denominator of which shall be the number of
                  shares of Common Stock outstanding immediately thereafter. So
                  long as any shares of Series A 



                                       7
<PAGE>

                  Preferred Stock are outstanding, the Corporation shall not
                  combine any shares of Common Stock unless it likewise combines
                  all shares of Common Stock.

                           (iii) If the Corporation shall at any time and from
                  time to time after the Purchase Date issue rights or warrants
                  to all holders of the Common Stock entitling such holders to
                  subscribe for or purchase Common Stock at a price per share
                  less than the Current Market Price per share of the Common
                  Stock on the record date for the determination of stockholders
                  entitled to receive such rights or warrants, then, and in each
                  such case, the number of shares of Common Stock into which
                  each share of Series A Preferred Stock is convertible shall be
                  adjusted so that the holder of each share thereof shall be
                  entitled to receive, upon the conversion thereof, the number
                  of shares of Common Stock determined by multiplying the number
                  of shares of Common Stock into which such share was
                  convertible on the day immediately prior to such record date
                  by a fraction, (A) the numerator of which is the sum of (1)
                  the number of shares of Common Stock outstanding on such
                  record date and (2) the number of additional shares of Common
                  Stock which such rights or warrants entitle holders of Common
                  Stock to subscribe for or purchase ("Offered Shares"), and (B)
                  the denominator of which is the sum of (1) the number of
                  shares of Common Stock outstanding on the record date and (2)
                  a fraction, (x) the numerator of which is the product of the
                  number of Offered Shares multiplied by the subscription or
                  purchase price of the Offered Shares and (y) the denominator
                  of which is the Current Market Price per share of Common Stock
                  on such record date. Such adjustment shall become effective
                  immediately after such record date.

                           (iv) If the Corporation shall be a party to any
                  transaction, including any capital reorganization,
                  reclassification or recapitalization involving the Common
                  Stock of the Corporation (other than (A) a transaction
                  described in clauses (i) and (ii) of this Section 5(c) or in
                  Section 3(b) or (B) a consummated Business Combination), or
                  some other form of transaction (other than a consummated
                  Business Combination) in which the previously outstanding
                  shares of Common Stock shall be changed into or, pursuant to
                  the operation of law or the terms of the transaction to which
                  the Corporation is a party, exchanged, or would have been
                  changed or exchanged as required by the Certificate of
                  Incorporation if such Common Stock were outstanding, for
                  different securities of the Corporation or common stock or
                  other securities of another corporation or interests in a
                  non-corporate entity (such other corporation or non-corporate
                  entity is referred to herein as the "Surviving Entity") or
                  other property (including cash) or any combination of the
                  foregoing, then, as a condition to the consummation of such
                  transaction, lawful and adequate provision shall be made
                  whereby the Holders of the Series A Preferred Stock shall
                  thereafter have the right to receive, in lieu of the shares of
                  Common Stock of the Corporation immediately theretofore
                  receivable with respect to the conversion of such shares of
                  Series A Preferred Stock, such shares of stock or securities
                  (such stock and securities are referred to herein as the
                  "Surviving Entity Securities") or assets as would have been



                                       8
<PAGE>


                  issued or payable with respect to or in exchange for the
                  shares of Common Stock which such holders would have held had
                  the shares of Series A Preferred Stock been converted
                  immediately prior to such transaction. In any such case,
                  appropriate provisions shall be made with respect to the
                  rights and interests of the Holders of the Series A Preferred
                  Stock to the end that such conversion rights (including,
                  without limitation, provisions for adjustment of the
                  Conversion Price) shall thereafter be
                  applicable, as nearly as may be practicable in relation to any
                  shares of Surviving Entity Securities or assets thereafter
                  deliverable upon the exercise thereof.

                  (d) Stock Transfer Taxes. The issuance of stock certificates
         upon the conversion of the Series A Preferred Stock shall be made
         without charge to the converting Holder for any tax in respect of such
         issuance. The Corporation shall not, however, be required to pay any
         tax which may be payable in respect of any transfer involved in the
         issuance and delivery of shares in any name other than that of the
         Holder of such shares of Series A Preferred Stock converted, and the
         Corporation shall not be required to issue or deliver any such stock
         certificate unless and until the person or persons requesting the
         issuance thereof shall have paid to the Corporation the amount of such
         tax, if any.

                  (e)      No Fractional Shares: Certificate as to Adjustments.

                           (i) No fractional shares shall be issued upon
                  conversion of the Series A Preferred Stock, and the number of
                  shares of Common Stock to be issued shall be rounded to the
                  nearest whole share.

                           (ii) Upon the occurrence of each adjustment or
                  readjustment of the Conversion Price of Series A Preferred
                  Stock pursuant to this Section 5, the Corporation, at its
                  expense, shall promptly compute such adjustment or
                  readjustment in accordance with the terms hereof and prepare
                  and furnish to each Holder of Series A Preferred Stock a
                  certificate setting forth such adjustment or readjustment and
                  showing in detail the facts upon which such adjustment or
                  readjustment is based. The Corporation shall, upon the written
                  request at any time of any Holder of Series A Preferred Stock,
                  furnish or cause to be furnished to such Holder a like
                  certificate setting forth (A) such adjustment and
                  readjustment, (B) the Conversion Price at the time in effect,
                  and (C) the number of shares of Common Stock and the amount,
                  if any, of other property which at the time would be received
                  upon the conversion of a share of Series A Preferred Stock.

                  (f) Notices of Record Date. In the event of any taking by the
         Corporation of a record of the Holders of any class of securities for
         the purpose of determining the Holders thereof who are entitled to
         receive any dividend (other than a cash dividend or a Liquidation
         Accretion Dividend) or other distribution, any right or warrant to
         subscribe for, purchase or otherwise acquire any shares of stock or any
         class of any other securities or property, or to receive any other
         right (including, without limitation, making a dividend or other


                                       9
<PAGE>


         distribution of any rights under a stockholder rights plan (sometimes
         known as a "poison pill" plan), whether now existing or hereafter
         created), the Corporation shall mail to each Holder of Series A
         Preferred Stock, at least 20 days prior to the date specified therein,
         a notice specifying the date on which any such record is to be taken
         for the purpose of such dividend, distribution, right or warrant, and
         the amount and character of such dividend, distribution, right or
         warrant. The Corporation shall not issue such dividend, distribution,
         right or warrant described herein or in Section 5(c)(iii), or
         consummate any Business Combination, or any reorganization,
         reclassification or recapitalization described in Section 5(c)(iv),
         unless it provides the Holders of the Series A Preferred Stock at least
         20 days advance written notice thereof.

                  (g) Reservation of Securities Issuable upon Conversion. The
         Corporation shall at all times reserve and keep available out of its
         authorized but unissued shares of Common Stock, solely for the purpose
         of effecting the conversion of the shares of the Series A Preferred
         Stock, free from any preemptive right or other obligation, such number
         of its shares of Common Stock as shall from time to time be sufficient
         to effect the conversion of all outstanding shares of the Series A
         Preferred Stock; and if at any time the number of authorized but
         unissued shares of Common Stock shall not be sufficient to effect the
         conversion of all then outstanding shares of the Series A Preferred
         Stock, in addition to such other remedies as shall be available to the
         Holder of such Series A Preferred Stock, the Corporation will take such
         corporate action as may be necessary to increase its authorized but
         unissued shares of Common Stock to such number of shares as shall be
         sufficient for such purposes. The Corporation shall prepare and shall
         use commercially reasonable efforts to obtain and keep in force such
         governmental or regulatory permits or other authorizations as may be
         required by law, and shall comply with all requirements as to
         registration, qualification or listing of the Common Stock in order to
         enable the Corporation to lawfully issue and deliver to each Holder of
         record of Series A Preferred Stock such number of shares of its Common
         Stock as shall from time to time be sufficient to effect the conversion
         of all Series A Preferred Stock then outstanding and convertible into
         shares of Common Stock, including, without limitation, compliance with
         the filing and waiting period requirements of the HSR Act.

                  (h) Notices. Any notice required by the provisions of this
         Section 5 to be given to the Holders of shares of Series A Preferred
         Stock shall only be effective upon receipt and may be given by personal
         delivery, U.S. certified mail, return receipt requested, or by a
         nationally recognized overnight delivery service (e.g., United Parcel
         Service or Federal Express), delivery or postage prepaid and addressed
         to each Holder of record at his address appearing on the books of this
         Corporation (and, in the case of any Holder that is a corporation ore
         other entity, to the attention of the President).

         6.       Redemption.

<PAGE>

                  (a) Optional Redemption. The Series A Preferred Stock may be
         redeemed (subject to (i) the right of any or all shares of Series A
         Preferred Stock to be converted into Common Stock at any time prior to
         the Redemption Date (as defined in Section 6(b)), and (ii) subject to
         the restrictions described in this Section 6(a) and the legal
         availability of funds therefor) at any time after the third anniversary
         of the Purchase Date, at the Corporation's option, in whole or in part,
         in the manner provided in Section 6(b), at a redemption price per share
         of Series A Preferred Stock (expressed as a percentage of the
         Liquidation Value, which includes the full accelerated amount of the
         Liquidation Accretion Dividends as prescribed by Section 3(a)(i)) set
         forth above), if redeemed during the 12-month period beginning on the
         anniversary date of the Purchase Date of each of the years set forth
         below:

         In the event a redemption of less than all of the outstanding shares of
         Series A Preferred Stock pursuant to this Section 6(a), the Corporation
         shall effect such redemption either prorata according to the number of
         shares held by each Holder of shares of Series A Preferred Stock, or by
         lot, in each case, as may be determined by the Corporation in its sole
         discretion.

                  (b)      Procedures for Redemption.

                           (i) At least 30 days and not more than 60 days prior
                  to the date fixed for any redemption of the Series A Preferred
                  Stock, written notice (the "Redemption Notice") shall be given
                  by first-class mail, postage prepaid, to each Holder of record
                  on the record date fixed for such redemption (the "Redemption
                  Date") of the Series A Preferred Stock at such Holder's
                  address as the same appears on the stock register of the
                  Corporation, provided that no failure to give such notice nor
                  any deficiency therein shall affect the validity of the
                  procedure for the redemption of any shares of Series A
                  Preferred Stock to be redeemed except as to the Holder or
                  Holders to whom the Corporation has failed to give said notice
                  or except as to the Holder or Holders whose notice was
                  defective; provided, further, that the Corporation may
                  withdraw such Redemption Notice and thereby have no obligation
                  to consummate the redemption described therein at any time
                  prior to the third day prior to the Redemption Date set forth
                  therein by providing written notice of such withdrawal to each
                  Holder who received such Redemption Notice. The Redemption
                  Notice shall state:

                                    (1)     the redemption price;


                                       11
<PAGE>

                                    (2) whether all or less than all the
                           outstanding shares of the Series A Preferred Stock
                           are to be redeemed and the total number of shares of
                           the Series A Preferred Stock being redeemed;

                                    (3) the number of shares of Series A
                           Preferred stock held, as of the appropriate record
                           date, by the Holder that the Corporation intends to
                           redeem;
                                    (4)     the Redemption Date;

                                    (5) that the Holder is to surrender to the
                           Corporation, at the place or places where
                           certificates for shares of Series A Preferred Stock
                           are to be surrendered for redemption, in the manner
                           and at the price designated, Holder's certificate or
                           certificates representing the shares of Series A
                           Preferred Stock to be redeemed; and

                                    (6) that cash dividends on the shares of the
                           Series A Preferred Stock to be redeemed shall cease
                           to accrue on such Redemption Date unless the
                           Corporation defaults in the payment of the redemption
                           price.

                           (ii) Each Holder of Series A Preferred Stock shall
                  surrender the certificate or certificates representing such
                  shares of Series A Preferred Stock to the Corporation, duly
                  endorsed, in the manner and at the place designated in the
                  Redemption Notice and on the Redemption Date. The full
                  redemption price for such shares of Series A Preferred Stock
                  shall be payable in cash to the person whose name appears on
                  such certificate or certificates as the owner thereof, and
                  each surrendered certificate shall be canceled and retired. In
                  the event that less than all of the shares represented by any
                  such certificate are redeemed, a new certificate shall be
                  issued representing the unredeemed shares.

                           (iii) Unless the Corporation defaults in the payment
                  in full of the applicable redemption price, cash dividends on
                  the shares of Series A Preferred Stock called for redemption
                  shall cease to accrue and accumulate on the Redemption Date,
                  and the Holders of such redeemed shares shall cease to have
                  any further rights with respect thereto from and after the
                  Redemption Date, other than the right to receive the
                  redemption price on the Redemption Date, without interest.

         7. Voting Rights. (a) The Holders of shares of Series A Preferred Stock
shall not be entitled to any voting rights, except as hereinafter provided in
Section 7(b) and Section 8 or as otherwise provided by law or by that certain
Governance Agreement between the Corporation, Sprint, Sprint L.P. and Dolphin,
Inc., a Delaware corporation, dated the Purchase Date (the "Governance
Agreement"). Notwithstanding any other provision of this Section 7 or Section 8,
the 

                                       12
<PAGE>

Holders of shares of Series A Preferred Stock shall not be entitled to any
voting rights hereunder with respect to a Business Combination which is not a
Discriminatory Transaction.

                  (b)      Election of Directors.

                           (i) Except as otherwise provided herein, at all times
                  from and after the Purchase Date, the Holders of shares of
                  Series A Preferred Stock shall have the right to elect two (2)
                  of the directors of the Corporation (the "Investor
                  Directors"). If the Corporation or any Significant Subsidiary
                  of the Corporation shall have a Strategic and Business
                  Planning Committee (or other committee responsible for
                  strategic and business planning) or a Finance Committee (or
                  other committee responsible for finance) during the time that
                  the Holders of Series A Preferred Stock shall have the right
                  to elect one or more Investor Directors under this Section
                  7(b)(i), such Investor Directors may appoint one of the
                  Investor Directors to each such committee. If there is no such
                  committee, the Holders of Series A Preferred Stock shall have
                  a reasonable opportunity to review and discuss the
                  Corporation's strategic and business plans and financing plans
                  with management of the Corporation prior to the submission of
                  any such plans to the Board of Directors of the Corporation or
                  any Significant Subsidiary of the Corporation. The Investor
                  Directors shall also have the right to appoint one Investor
                  Director to each of the other committees of the Board of
                  Directors, except as otherwise provided in this Section 7(b)
                  and except for appointments to any existing committee of the
                  Board of Directors if the scope of authority of such committee
                  is not hereafter expanded. The Holders of Series A Preferred
                  Stock shall receive copies of all information and materials
                  provided to the directors of the Corporation and any
                  Signifanct Subsidiary of the Corporation or to committee
                  members, except for information and materials provided to a
                  committee that an Investor Director is prohibited from
                  participating in as set forth in this Section 7(b)(i), at the
                  time such information and materials are provided to such
                  directors. Notwithstanding the foregoing, nothing set forth
                  herein shall entitle any Investor Director to participate on
                  any committee of the Board of Directors of the Corporation or
                  any Significant Subsidiary of the Corporation created for the
                  purpose of considering a Business Combination, an Acquisition
                  Proposal, a Sprint Offer or a Qualified Offer, or to
                  participate in the Board's deliberations with respect to any
                  of the foregoing.

                           (ii) Notwithstanding anything in the Section 7(b)(i)
                  to the contrary, if at the end of any three consecutive
                  months, (A) Sprint's Percentage Interest shall be less than
                  the Higher Threshold, the Holders shall promptly take action
                  to cause one of its Investor Directors to resign from the
                  Board, or (B) Sprint's Percentage Interest shall be less than
                  the Lower Threshold, the Holders shall promptly take action to
                  cause any and all remaining Investor Directors to resign from
                  the Board; and, upon resignation of each respective Investor
                  Director, the Holders of shares of Series A Preferred 


                                       13
<PAGE>

                  Stock shall forever cease to have any voting rights with
                  respect to the election of that director.

                           (iii) Except as otherwise provided in Section
                  7(b)(ii), the Holders of Series A Preferred Stock shall have
                  the right to elect any replacement for an Investor Director
                  designated for nomination or nominated in accordance with this
                  Section 7(b) upon the death, resignation, retirement,
                  disqualification or removal from office for other cause of
                  such Director.

                           (iv) Until the date the Governance Agreement is
                  terminated in accordance with Section 7.01 thereof, and for
                  the duration of any period in which Sprint's Percentage
                  Interest is greater than the Lower Threshold, the Investor
                  Directors shall have the approval rights set forth in Section
                  2.06 of the Governance Agreement.

         8.       Protective Provisions.

                  (a) Class Voting. So long as shares of Series A Preferred
         Stock are outstanding, this Corporation shall not, without first
         obtaining the approval (by vote or written consent) of the Holders of
         sixty-six and two-thirds percent (662/3%) of the then outstanding
         shares of Series A Preferred Stock (voting as a class):

                           (i) alter or change the rights, preferences or
                  privileges of the shares of Series A Preferred Stock so as to
                  affect adversely the shares;

                           (ii) increase the number of authorized shares of
                  Series A Preferred Stock, or create any new series of stock or
                  any other securities convertible into equity securities of the
                  Corporation having a preference over, or being on a parity
                  with, the Series A Preferred Stock with respect to voting,
                  dividends, distribution of assets upon liquidation,
                  dissolution, winding up or otherwise or conversion rights;

                           (iii) amend the Certificate of Incorporation, Bylaws
                  or other organizational documents of the Corporation or take
                  any action or enter into any other agreements which, prohibit
                  or materially conflict with the Corporation's obligations
                  hereunder with respect to the Holders of Series A Preferred
                  Stock; or

                           (iv)     engage in a Liquidation Event.

                  (b) No Impairment. The Corporation will not, by amendment of
         its Certificate of Incorporation, Bylaws or other organizational
         documents or through any reorganization, reclassification,
         recapitalization, Liquidation Event, issue or sale of securities or any
         other voluntary action by the Corporation, avoid or seek to avoid the
         observance or performance of any of the terms to be observed or
         performed hereunder by the Corporation but will at all times in good
         faith assist in the carrying out of all the provisions of this
         Certificate of 


                                       14
<PAGE>


         Designation, and in the taking of all such action as may be necessary
         or appropriate in order to protect the conversion and other rights of
         the Holders of the Series A Preferred Stock against impairment;
         provided, however, that the protection provided by this Section 8(b)
         shall not apply to a Business Combination in which (i) neither the
         Liquidation Value nor the Conversion Price of the Series A Preferred
         Stock is changed, and (ii) the Holders of Series A Preferred Stock
         shall be entitled to receive consideration at the same time, and in the
         same amount and in the same form per share, as if each share of Series
         A Preferred Stock had been converted into Common Stock immediately
         prior to such Business Combination, after giving effect to the
         acceleration of the full amount of all of the Liquidation Accretion
         Dividends as contemplated by the last sentence of Section 3(a)(i).
         Without limiting the foregoing, but subject to the proviso in the
         immediately preceding sentence, the Corporation will not effect any
         transaction described in this Section 8(b), the result of which is to
         adversely affect any of the rights of Holders of Common Stock relative
         to the rights of Holders of any other securities other than the Series
         A Preferred Stock.

                  (c) Tolling of Automatic Conversion and Other Time periods for
         HSR Compliance. Notwithstanding any other provision of this Certificate
         of Designation, until such time as the filing and waiting period
         requirements of the HSR Act relating to the conversion of any of the
         shares of Series A Preferred Stock pursuant to Section 5 shall have
         been complied with, if any, and there shall be no action taken or
         instituted by the United States Department of Justice or the United
         States Federal Trade Commission to delay, enjoin or impose conditions
         on such conversion, and such waiting period applicable under the HSR
         Act shall have expired or received early termination: (i) there shall
         be no automatic conversion of the Series A Preferred Stock into Common
         Stock, (ii) the Redemption Date shall be automatically extended for a
         period of five Business Days beyond the latest date contemplated by the
         first sentence of Section 6(b)(i) (as so extended, the "Extended
         Redemption Date") and each Holder of shares of Series A Preferred Stock
         shall be entitled to convert any or all of such shares into Common
         Stock prior to the Extended Redemption Date, and (iii) each other date
         or event that would otherwise impair any right to convert the Series A
         Preferred Stock into Common Stock or otherwise impair the rights of the
         Series A Preferred Stock shall be tolled until 10 days after the
         expiration or early termination of all waiting periods under the HSR
         Act; provided, however, that no cash dividends shall accrue during the
         period after the date originally set for redemption pursuant to Section
         6. Any Holder who is required to comply with the filing and waiting
         period requirements of the HSR Act with respect to the conversion of
         any shares of Series A Preferred Stock shall use commercially
         reasonable efforts to cause such filing to be made as soon as
         practicable after such Holder has provided notice of its intention to
         convert such shares of Series A Preferred Stock and to diligently and
         in good faith pursue expiration or termination of the waiting period of
         the HRS Act.

         9. Stockholder Rights Plan. Notwithstanding any other provision of this
Certificate of Designation to the contrary, if the Corporation shall adopt a
stockholders rights plan (sometimes known as a "poison pill" plan), and shall
declare, order, pay or make a dividend or other distribution 


                                       15
<PAGE>


of rights thereunder with respect to the Common Stock (whether or not separate
from the Common Stock), each Holder of shares of Series A Preferred Stock shall
be entitled to receive from the Corporation, upon conversion of such shares of
Series A Preferred Stock into Common Stock pursuant to Section 5, all of the
rights distributed under such plan (but without any limitation or restriction or
the exercise of such rights that are not also applicable to holders of Common
Stock) fully and to the same extent as if immediately prior to the earlier of
such distribution or any record date therefor (i) the Liquidation Value of such
shares of Series A Preferred Stock had then increased by the full amount of all
Liquidation Accretion Dividends payable as if such shares of Series A Preferred
Stock had been held through and including the first Dividend Payment Date on or
following the fifth anniversary of the Purchase Date, and (ii) such Holder had
then converted all of such Holder's shares of Series A Preferred Stock into
shares of Common Stock. The preceding sentence shall provide the exclusive
protection under this Certificate of Designation to the Holders of the Series A
Preferred Stock (including any adjustments that would otherwise be required by
Section 5(c)) with respect to the subject matter of the immediately preceding
sentence.

         10. Status of Converted Stock. In the event any shares of Series A
Preferred Stock shall be converted pursuant to Section 5 hereof, the shares so
converted shall be canceled and thereupon restored to the status of authorized
but unissued Preferred Stock undesignated as to class or series.

         11. Certain Definitions. For purposes of this Certificate of
Designation, Preferences and Rights of Series A Preferred Stock, unless the
context otherwise requires:

                           (i) "Acquisition Proposal" shall have the meaning set
                  forth in the Governance Agreement.

                           (ii) "Affiliate" and "Associate" shall have the
                  respective meanings ascribed to such terms in Rule 12b-2 under
                  the Exchange Act as such Rule is in effect on the Purchase
                  Date.

                           (iii) A Person shall be deemed to "beneficially own,"
                  any securities:

                                    (A) which such Person or any of such
                           Person's Affiliates or Associates, directly or

                                  THE CREDITS

     SECTION 2.01.  Advances.  (a)  From and after the Closing, but prior to the
Facility Termination Date, Sprint agrees, on the terms and subject to the
conditions set forth in this Agreement, to make Advances to the Borrowers from
time to time in amounts not to exceed the Aggregate Available Commitment
existing at such time. Although the Borrowers may obtain multiple Advances
hereunder, this is not a revolving line of credit and Advances may not be repaid
and re-advanced. Prepayment may only be made in accordance with Sections 3.07
                                                                -------------
and 3.08.
- - -------- 

     (b)  The Borrowers, jointly and severally, agree that if at any time the
outstanding balance of the Loan exceeds the Aggregate Commitment, the Borrowers
shall repay immediately the then outstanding Loan balance in such amount as is
necessary to eliminate such excess.

     (c)  The Borrowers' obligation to pay the principal of, and interest on,
each Advance shall be evidenced by a Note executed by the Borrowers in the
principal amount equal to such Advance and dated the date of such Advance.  Each
Borrower's joint and several obligations as co-maker of each Note shall exist
regardless of which Borrower actually receives the applicable Advance.

Each Advance shall mature, and the principal amount thereof and any unpaid
accrued interest thereon shall be due and payable, on the 5/th/ anniversary of
the Borrowing Date for such Advance (or as otherwise provided in the related
Note or in Section 3.08).
           ------------  

     SECTION 2.02.  Facility Termination Date. The Facility Termination Date is
the date after which Sprint is no longer obligated to make Advances hereunder
and shall occur upon the first to occur of the following:

     (a)  The 5/th/ anniversary of the Closing;

     (b)  Acceleration by Sprint in accordance with the provisions of Article
          VIII;

     (c)  Consummation of a Business Combination; or

     (d)  Termination of the Marketing Agreement other than a termination by
          Sprint under Section 24(b)(ii) thereof and other than a termination by
          the Company under Section 24(c), 24(d)(i) and 24(d)(ii) thereof.

                                       11
<PAGE>
 
Such termination of the credit facility shall not affect in any way Sprint's
rights, including the Conversion Rights and rights to accelerate the Loans,
under this Agreement and the Notes.

     SECTION 2.03.  Minimum Amount of Each Advance. Each Advance shall be in the
minimum amount of $5,000,000 (and in multiples of $1,000,000 if in excess
thereof); provided, however, that any Advance may be in the amount of the
          --------  -------                                              
Aggregate Available Commitment.

     SECTION 2.04.  Commitment Increases. Sprint shall not be obligated to make
any Advance prior to the Closing.  From and after the Closing the "Aggregate
Commitment" shall be $25,000,000 and shall be automatically increased by the
following amounts on the following dates:

     SECTION 2.05.  Borrowing Notices for New Advances. Newco shall give Sprint
irrevocable notice containing the following information (a "Borrowing Notice")
                                                            ----------------
not later than 10:00 a.m. (Kansas City time) at least ten (10) Business Days and
not more than twenty (20) Business Days before the proposed Borrowing Date of
each Advance:

          (a)  the proposed Borrowing Date, which shall be a Business Day, of
     such Advance;

          (b)  the aggregate amount of such Advance;

          (c)  a statement to the effect that all of the representations and
     warranties of each Borrower contained herein are true and correct (i) as of
     the date referred to in any representation or warranty that addresses a
     matter as of a particular date and (ii) as to all other representations and
     warranties as of the date of such Borrowing Notice, unless in either the
     case of clause (i) or (ii), the inaccuracies under such representations and
     warranties would not, individually or in the aggregate, have a Material
     Adverse Effect; and

          (d)  a description of any Default that exists as to which the proviso
     of clause (g) in Article IV may apply.

Subject to the terms hereof and subject to the satisfaction of the conditions
set forth in Article IV, Sprint shall, not later than noon (Kansas City time) on
             ----------                                                         
each Borrowing Date, make available to Newco immediately available funds in the
amount of the Advance requested to be made on such Borrowing Date.

                                       12
<PAGE>
 
     SECTION 2.06.  Rates Applicable After an Event of Default. During the
continuance of an Event of Default, Sprint may, at its option, by notice to the
Borrowers (which notice may be revoked at the option of Sprint), declare that
for the duration of time during which such Event of Default shall be continuing,
the outstanding balance of the Loan shall bear a floating rate of interest equal
to the Prime Rate, as in effect from time to time, plus five percent (5%) per
annum calculated for actual days elapsed on the basis of a 360-day year.

     SECTION 2.07.  Method of Payment. All payments of the Obligations hereunder
shall be made, without setoff, deduction or counterclaim, in immediately
available funds to Sprint pursuant to wire transfer instructions provided to the
Borrowers by a duly authorized executive officer of Sprint, or absent such
instructions, at Sprint's address specified pursuant to Section 11.01, on the
                                                        -------------         
date when due. If the Borrowers shall be required by law to deduct any such
amounts from or in respect of any sum payable hereunder to Sprint, then the sum
payable hereunder shall be increased so that, after making all required
deductions, Sprint receives an amount equal to the sum it would have received
had no such deduction been made, and the Borrowers, jointly and severally, shall
indemnify Sprint for taxes, assessments and governmental charges imposed by any
jurisdiction on account of amounts paid or payable pursuant to this sentence.
Within 30 days after the date of any payment of any such amount withheld by
either Borrower in respect of any payment to Sprint, such Borrower shall furnish
to Sprint the original or certified copy of a receipt evidencing payment
thereof.

     SECTION 2.08.  Notes.  Upon receipt of a Borrowing Notice, Sprint shall
deliver to the Borrowers a Note for execution by the Borrowers; provided,
                                                                -------- 
however, that Sprint may refuse to deliver such Note if Sprint is not obligated
- - -------
to make an Advance hereunder.
 
     SECTION 2.09.  Interest Rate; Interest Payment Dates; Interest and Fee
Basis. Interest on principal shall be payable at a rate equal to six percent
(6%) per annum, provided, however, such interest rate may be increased as
provided in this Agreement under certain circumstances to a floating rate equal
to five percent (5%) above the Prime Rate. Interest accrued on each Advance
shall be payable on each Payment Date, commencing with the first Payment Date to
occur after the Borrowing Date, on any date on which principal is prepaid,
whether due to acceleration or otherwise, and at maturity. Interest shall be
calculated for actual days elapsed on the basis of a 360-day year. Interest
shall be payable for the day an Advance is made but not for the day of any
payment on the amount paid if payment is received prior to noon (Kansas City
time) at the place of payment. If any payment of principal of or interest on an
Advance shall become due on a day which is not a Business Day, such payment
shall be made on the next succeeding Business Day and, in the case of a
principal payment, such extension of time shall be included in computing
interest in connection with such payment.

     SECTION 2.10.  Waivers; Special Agreements of Borrowers. Each Borrower
warrants to Sprint that it has adequate means to obtain from the other Borrower,
on a continuing basis, information concerning the financial condition of such
other Borrower, and that it is not relying on Sprint to provide such
information, now or in the future. Each Borrower hereby waives any act or
omission of Sprint (except acts or omissions in bad faith) that materially
increases the scope of such 

                                       13
<PAGE>
 
Borrower's risk, including negligent administration of the loan. As a condition
of payment or performance by either Borrower, Sprint is not required to seek to
enforce any remedies against the other Borrower or any other party liable to
Sprint on account of the Obligations; nor is Sprint required to seek to enforce
or resort to any remedies with respect to any Lien granted to Sprint by the
other Borrower or any other party on account of the Obligations. This Agreement
and the Notes shall remain fully enforceable against a Borrower irrespective of
any defenses which the other Borrower may assert with respect to the
Obligations, including failure of consideration, breach of warranty, fraud,
payment, statute of frauds, bankruptcy, lack of legal capacity, statute of
limitations, lender liability, accord and satisfaction and usury.


                                  ARTICLE III

                           CONVERSION AND PREPAYMENT

     SECTION 3.01.  Conversion. Sprint or a permitted assignee (in either case,
a "Holder") of a Note shall have conversion rights as follows (the "Conversion
Rights"):

          (a)  Optional Conversion Rights and Automatic Conversion.

               (i)    Each Note shall be convertible, in whole or in part, at
          the option of the Holder thereof, at any time, and from time to time,
          at the office of Newco into such number of validly issued, fully paid
          and nonassessable shares of Newco Common Stock, free and clear of all
          Liens of any kind or nature whatsoever, as is determined by dividing
          the outstanding principal balance of such Note at the time of such
          conversion, or the part thereof converted by the Holder, by the
          Conversion Price per share at the time in effect for such Note;
          provided, however, any such conversion shall be in the following
          minimum amounts ("Minimum Conversion Amounts"): (1) If the aggregate
          principal amount of the Notes outstanding at the time of such
          conversion is less than $5,000,000 then the Minimum Conversion Amount
          is such aggregate principal amount; or (2) If the aggregate principal
          amount of the Notes is more than $5,000,000, then the Minimum
          Conversion Amount is equal to $5,000,000 plus such multiples of
          $1,000,000 as the Holder may elect. The Conversion Price per share for
          each Note shall be an amount equal to 130% times the Average Market
          Price of the Newco Common Stock, calculated with reference to the
          related Borrowing Date, which amount shall be inserted in each Note at
          the time of its original issuance in the appropriate space identifying
          the Conversion Price of such Note, subject to adjustment as
          hereinafter provided. It is understood that the Conversion Price for
          each Note, if there is more than one Note, may be different. The
          Conversion Price for each Note shall be subject to adjustment, from
          time to time as set forth in Section 3.01(c).
                                       --------------- 

                                       14
<PAGE>
 
               (ii)   Upon conversion of all or part of the then outstanding
          principal balance of a Note, payment shall be made for all accrued but
          unpaid interest on that portion of such Note converted through the
          date of conversion.

          (b)  Mechanics of Conversion.  If the Holder of a Note desires to
     exercise such right of conversion, such Holder shall give written notice to
     Newco (the "Conversion Notice") of that Holder's election to convert a
     stated amount of the principal balance (the "Conversion Amount") into
     shares of Newco Common Stock, and surrender to Newco, at its principal
     office or at such other office or agency maintained by Newco for such
     purpose, the originally executed Note evidencing such Conversion Amount.
     The Conversion Notice shall also contain a statement of the name or names
     (with addresses) in which the certificate or certificates for Newco Common
     Stock shall be issued. Notwithstanding the foregoing, Newco shall not be
     required to issue any certificates to any person other than the Holder of
     the converted Note unless Newco has obtained reasonable assurance that such
     transaction is exempt from the registration requirements of, or is covered
     by an effective registration statement under, the Securities Act of 1933,
     as amended (the "Act"), and all applicable state securities laws,
     including, if necessary in the reasonable judgment of Newco or its legal
     counsel, receipt of an opinion to such effect from counsel reasonably
     satisfactory to Newco. In no event would such opinion be required if the
     shares of Newco Common Stock could, upon conversion, be resold pursuant to
     Rule 144 or Rule 144A under the Act. Promptly as practicable, and in any
     event within five business days (subject to the last sentence of Section
     3.01(c)(v)), after the receipt of the Conversion Notice and the surrender
     of the Note evidencing at least the Conversion Amount, Newco shall issue
     and deliver, or cause to be delivered, to the Holder of such Note or his
     nominee or nominees, (i) a certificate or certificates for the number of
     shares of Newco Common Stock issuable upon the conversion of such
     Conversion Amount and (ii) if the Conversion Amount is less than the total
     outstanding principal balance of the converted Note which is surrendered, a
     new Note, of like tenor, evidencing the remaining portion of the
     outstanding principal balance which is not converted.  Such conversion
     shall be deemed to have been effected as of the close of business on the
     date Newco received the Conversion Notice and the originally executed Note
     representing at least the Conversion Amount, and the person or persons
     entitled to receive the shares of Newco Common Stock issuable upon
     conversion shall be treated for all purposes as the holder or holders of
     record of such shares of Newco Common Stock as of the close of business on
     such date.

          (c)  Conversion Price Adjustments.

               (i)    If Newco should at any time or from time to time after the
          date of the Advance evidenced by a Note fix a record date for the
          effectuation of a split or subdivision of the outstanding shares of
          Newco Common Stock or the determination of holders of Newco Common
          Stock entitled to receive a dividend or other distribution payable in
          additional shares of Newco Common Stock, then, as of such record date
          (or, if no record date is fixed, as of the close of business on the
          date on 

                                       15
<PAGE>
 
          which the Board of Directors of Newco adopts the resolution relating
          to such dividend, distribution, split or subdivision), the Conversion
          Price for such Note shall be decreased to equal the product of the
          Conversion Price in effect immediately prior to such date for such
          Note multiplied by a fraction, the numerator of which shall be the
          number of shares of Newco Common Stock outstanding immediately prior
          thereto and the denominator of which shall be the number of shares of
          Newco Common Stock outstanding immediately thereafter.

               (ii)   If the number of shares of Newco Common Stock outstanding
          at any time or from time to time after the date of the Advance
          evidenced by a Note is decreased by a combination of the outstanding
          shares of Newco Common Stock, then following such combination, the
          Conversion Price shall be increased to equal the product of the
          Conversion Price in effect immediately prior thereto for such Note
          multiplied by a fraction, the numerator of which shall be the number
          of shares of Newco Common Stock outstanding immediately prior thereto
          and the denominator of which shall be the number of shares of Newco
          Common Stock outstanding immediately thereafter. So long as any of the
          Notes are outstanding, Newco shall not combine any shares of Newco
          Common Stock unless it likewise combines all shares of Newco Common
          Stock.

               (iii)  If Newco shall at any time and from time to time after the
          date of the Advance evidenced by a Note issue rights or warrants to
          all holders of the Newco Common Stock entitling such holders to
          subscribe for or purchase Newco Common Stock at a price per share less
          than the Current Market Price per share of the Newco Common Stock on
          the record date for the determination of stockholders entitled to
          receive such rights or warrants, then, and in each such case, the
          Conversion Price shall be adjusted so that the Holder of such Note
          shall be entitled to receive, upon the conversion thereof, the number
          of shares of Newco Common Stock determined by multiplying the number
          of shares of Newco Common Stock into which such Note was convertible
          on the day immediately prior to such record date by a fraction, (A)
          the numerator of which is the sum of (1) the number of shares of Newco
          Common Stock outstanding on such record date and (2) the number of
          additional shares of Newco Common Stock which such rights or warrant
          entitle holders of Common Stock to subscribe for or purchase ("Offered
          Shares"), and (B) the denominator of which is the sum of (1) the
          number of shares of Newco Common Stock outstanding on the record date
          and (2) a fraction, (x) the numerator of which is the product of the
          number of Offered Shares multiplied by the subscription or purchase
          price of the Offered Shares and (y) the denominator of which is the
          Current Market Price per share of Newco Common Stock on such record
          date.  Such adjustment shall become effective immediately after such
          record date.

               (iv)   If Newco shall be a party to any transaction, including
          any capital reorganization or reclassification of the Newco Common
          Stock (other than a 

                                       16
<PAGE>
 
          transaction described in clauses (i), (ii) and (v) of this Section
                                                                     -------
          3.01(c)), or consolidation or merger of Newco, or the sale or
          --------
          conveyance of all or substantially all of its assets in which the
          previously outstanding shares of Newco Common Stock shall be changed
          into or, pursuant to the operation of law or the terms of the
          transaction to which Newco is a party, exchanged, or would have been
          changed or exchanged as required by the Certificate of Incorporation
          if such Newco Common Stock were outstanding, for different securities
          of Newco or common stock or other securities of another company or
          interests in a non-corporate entity (such other company or non-
          corporate entity is referred to herein as the "Surviving Entity") or
          other property (including cash) or any combination of the foregoing,
          then, as a condition to the consummation of such transaction, lawful
          and adequate provision shall be made whereby each Holder of a Note
          shall thereafter have the right to receive, in lieu of the shares of
          Newco Common Stock immediately theretofore receivable with respect to
          the conversion of such Holder's Note, such shares of stock or
          securities (such stock and securities are referred to herein as the
          "Surviving Entity Securities") or assets as are issued or are payable
          with respect to or in exchange for the shares of Newco Common Stock
          which such Holder would have held had his Note been converted in full
          immediately prior to such transaction. In any such case, appropriate
          provisions shall be made with respect to the rights and interests of
          each Holder of a Note to the end that such conversion rights
          (including, without limitation, provisions for adjustment of the
          Conversion Price) shall thereafter be applicable, as nearly as may be
          practicable in relation to any shares of Surviving Entity Securities
          or assets thereafter deliverable upon the exercise thereof.

               (v)    If Newco shall at any time or from time to time after the
          date of an Advance declare, order, pay or make a dividend or other
          distribution (including, without limitation, any distribution of stock
          or other securities or property or rights or warrants to subscribe for
          securities of Newco or any of its Subsidiaries by way of dividend) on
          Newco Common Stock, other than (x) regular quarterly dividends payable
          in cash or extraordinary cash dividends in an aggregate amount not to
          exceed in any Fiscal Quarter an amount equal to 6.25% of the Net
          Income for the twelve-month period ending on the day immediately
          preceding the first day of such Fiscal Quarter, (y) shares of Newco
          Common Stock which are referred to in clause (i) of this Section

          (iii) of this Section 3.01(c), then, as a condition to the
                        --------------                              
          consummation of such dividend or distribution, the Conversion Price of
          each Note shall be adjusted so that the Holder of each Note shall be
          entitled to receive, upon the conversion of the Note, the number of
          shares of Common Stock determined by multiplying (1) the number of
          shares of Newco Common Stock into which such share was convertible on
          the day immediately prior to the record date fixed for the
          determination of stockholders entitled to receive such dividend or
          distribution by (2) a fraction, the numerator of which shall be the
          Current Market Price per share of Newco Common Stock as of the third
          Trading Day prior to such record date, and the denominator of which
          shall be such Current Market 

                                       17
<PAGE>
 
          Price per share of Newco Common Stock less the Fair Market Value per
          share of Newco Common Stock (as determined in good faith by the Board
          of Directors of Newco, a certified resolution with respect to which
          shall be mailed to each Holder of a Note) of such dividend or
          distribution; provided, however, that in the event of a distribution 
                        --------  ------- 
          of shares of capital stock of a Subsidiary of Newco (a "Spin-Off")
          made to holders of shares of Newco Common Stock, the numerator of such
          fraction shall be the sum of the Current Market Price per share of
          Newco Common Stock and the Current Market Price of the number of
          shares (or the fraction of a share) of capital stock of the Subsidiary
          which is distributed in such Spin-Off in respect of one share of Newco
          Common Stock and the denominator of which shall be the Current Market
          Price per share of Newco Common Stock. An adjustment made pursuant to
          this clause (v) shall be made upon the opening of business on the next
          Business Day following the date on which any such dividend or
          distribution is paid and shall be effective retroactively to such time
          immediately after the close of business on the record date fixed for
          the determination of stockholders entitled to receive such dividend or
          distribution; provided, however, if the proviso in the foregoing
                        --------  ------- 
          sentence applies, then such adjustment shall be made and be effective
          as of the 30th Trading Day after the effective date of such Spin-Off,
          and in the event all or part of this Note is converted after the
          record date for such Spin-Off but prior to the 30th Trading Day after
          the effective date of the Spin-Off, Newco will deliver to the holder
          of this Note in accordance with Section 3.01(b) that number of shares
                                          --------------- 
          which would be issued prior to the appropriate adjustment, and issue
          the additional number of shares which would be issuable as a result of
          the applicable adjustment pursuant to this clause (v) within 35
          Trading Days after the effective date of such Spin-Off.

     SECTION 3.02.  No Impairment. Newco will not, by amendment of its
Certificate of Incorporation, Bylaws or other organizational documents or
through any reorganization, reclassification, recapitalization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by Newco but will at all
times in good faith assist in the carrying out of all the provisions of Section
                                                                        -------
3.01 and in the taking of all such action as may be necessary or appropriate in
- - ----
order to protect the Conversion Rights of each Holder of the Notes against
impairment.  Without limiting the foregoing, Newco will not effect any
transaction described in this Section 3.02, the result of which is to adversely
                              ------------                                     
affect any of the rights of holders of Newco Common Stock relative to the rights
of holders of any other securities of Newco other than the Notes.

     SECTION 3.03.  Stock Transfer Taxes. The issuance of stock certificates
upon the conversion of a Note shall be made without charge to the Holder thereof
for any tax in respect of such issuance. Newco shall not, however, be required
to pay any tax which may be payable in respect of any transfer involved in the
issuance and delivery of shares in any name other than that of the Holder of the
applicable Note, and Newco shall not be required to issue or deliver any such
stock 

                                       18
<PAGE>
 
certificate unless and until the person or persons requesting the issuance
thereof shall have paid to Newco the amount of such tax, if any.

     SECTION 3.04.  No Fractional Shares: Certificate as to Adjustments. (a) No
fractional shares shall be issued upon conversion of a Note, and the number of
shares of Common Stock to be issued shall be rounded to the nearest whole share.

     (b)  Upon the occurrence of each adjustment or readjustment of the
Conversion Price of a Note pursuant to Section 3.01(c), Newco, at its expense,
                                       ---------------                        
shall promptly compute such adjustment or readjustment in accordance with the
terms hereof and prepare and furnish to the Holder of each Note a certificate
setting forth such adjustment or readjustment for such Holder's Note and showing
in detail the facts upon which such adjustment or readjustment is based.  Newco
shall, upon the written request at any time by a Holder of a Note, furnish or
cause to be furnished to such Holder a like certificate setting forth (A) such
adjustment and readjustment, (B) the Conversion Price at the time in effect for
such Note, and (C) the number of shares of Newco Common Stock and the amount, if
any, of other property which at the time would be received upon the total
conversion of such Note.

     SECTION 3.05.  Notices of Record Date. In the event of any taking by Newco
of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend (other
than a cash dividend) or other distribution, any right to subscribe for,
purchase or otherwise acquire any shares of stock or any class of any other
securities or property, or to receive any other right, Newco shall mail to each
Holder of the Notes, at least ten (10) Business Days prior to the date specified
therein, a notice specifying the date on which any such record is to be taken
for the purpose of such dividend, distribution or right, and the amount and
character of such dividend, distribution or right. Newco shall not issue rights
or warrants described in Section 3.01(c)(iii), consummate any reorganization,
                         --------------------                                
reclassification, consolidation, merger or sale described in Section
                                                             -------
3.01(c)(iv), or dividend or distribution described in Section 3.01(c)(v), unless
- - -----------                                           ------------------
it provides each Holder of the Notes at least ten (10) Business Days advance
notice thereof.

     SECTION 3.06.  Reservation of Securities Issuable upon Conversion. Newco
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the Notes, free from any preemptive right or other obligation, such number of
its shares of Newco Common Stock as shall from time to time be sufficient to
effect the conversion of all of the outstanding principal balance of the Notes
issued under this Agreement; and if at any time the number of authorized but
unissued shares of Newco Common Stock shall not be sufficient to effect the
conversion of all of the outstanding principal balance of the Notes issued under
this Agreement, in addition to such other remedies as shall be available to the
Holders of the Notes, Newco will take such corporate action as may be necessary
to increase its authorized but unissued shares of Newco Common Stock to such
number of shares as shall be sufficient for such purposes. Newco shall prepare
and shall use its best efforts to obtain and keep in force such governmental or
regulatory permits or other authorizations as may be required by law, and shall
comply with all requirements as to registration, qualification or listing of the
Newco Common Stock in order to enable Newco to lawfully issue and deliver to the
Holders of the Notes such number 

                                       19
<PAGE>
 
of shares of its Newco Common Stock as shall from time to time be sufficient to
effect the conversion of all of the outstanding principal balance of the Notes
issued under this Agreement.

     SECTION 3.07.  Prepayment. From and after the date which is 42 months after
the Borrowing Date applicable to a Note, the Borrowers shall have the right to
prepay such Note, upon not less than thirty (30) nor more than sixty (60) days'
prior notice setting forth the amount (each prepayment shall be made in the
minimum amount of $5,000,000 and in $1,000,000 increments over the minimum
amount) that it wishes to prepay of such Note and the date of such prepayment
("Prepayment Notice"). In the event that the Borrowers prepay a Note in part,
the Borrowers shall execute and deliver to Holder a new Note in a principal
amount equal to the principal remaining outstanding. Delivery of a Prepayment
Notice shall not affect Holder's right to convert any such Note, in whole or in
part, prior to the date set for prepayment.

     SECTION 3.08.  Mandatory Prepayments. (a) Newco or the Company shall, as
the case may be, notify Sprint that it intends to enter into a Business
Combination or that a Business Combination may occur at least thirty (30) days
prior to consummation of such proposed Business Combination, setting forth in
such notice all the material facts relating to the Business Combination. Prior
to the consummation of such Business Combination, the Holders shall continue to
have the right to convert the Notes as herein provided. From and after the
consummation of such Business Combination and for a thirty (30) day period
thereafter, the Holders shall have the right to require the Borrowers to prepay
all principal and accrued interest on the Notes (calculating accrued interest to
the date of such prepayment), plus an amount equal to 1% of the principal amount
of such Notes. Such mandatory prepayment shall be made on or before the tenth
day after notice is given by Sprint to the Borrowers demanding such prepayment.

     (b)  In the event the Facility Termination Date occurs pursuant to Section
2.02(d), then each of the Notes outstanding hereunder shall be required to be
prepaid, without the necessity of any notice or demand by Sprint or any Holder,
on or before the first Business Day following the end of one year after such
Facility Termination Date.

     (c)  The foregoing provisions of this Section 3.08 shall not affect in any
                                           ------------                        
way the obligation of the Borrowers to pay any Note on its maturity date if such
maturity date is earlier than the required prepayment date.

     SECTION 3.09.  Stockholder Rights Plan. Notwithstanding any other provision
of this Agreement to the contrary, if Newco shall adopt a stockholders rights
plan (sometimes known as a "poison pill" plan), and shall declare, order, pay or
make a dividend or other distribution of rights thereunder with respect to the
Newco Common Stock (whether or not separate from the Newco Common Stock), each
Holder of a Note shall be entitled to receive from Newco, upon conversion of
such Note into Newco Common Stock pursuant to Article III, all of the rights
distributed under such plan (but without any limitation or restriction on the
exercise of such rights) fully and to the same extent as if immediately prior to
the earlier of such distribution or any record date therefor such Holder had
converted all of such Holder's outstanding principal balance on the Notes into
shares of 

                                       20
<PAGE>
 
Newco Common Stock. The preceding sentence shall provide the exclusive
protection under this Agreement to the Holders of the Notes (including
adjustments that would otherwise be required by Section 3.01(c)) with respect to
the subject matter of the immediately preceding sentence.

     SECTION 3.10.  Tolling of Automatic Conversion and Other Time periods for
HSR Compliance. Notwithstanding any other provision of this Agreement to the
contrary, until such time as the filing and waiting period requirements of the
HSR Act relating to the conversion of any of the Notes into Common Stock
pursuant to Article III shall have been complied with, if any, and there shall
be no action taken or instituted by the United States Department of Justice or
the United States Federal Trade Commission to delay, enjoin or impose conditions
on such conversion, and such waiting period applicable under the HSR Act shall
have expired or received early termination: (i) the date for any prepayments
pursuant to Section 3.07 or 3.08 shall be automatically extended for a period of
            --------------------                                                
five (5) Business Days beyond the date of expiration or early termination of the
waiting period of the HSR Act (as so extended, the "Extended Redemption Date")
and each Holder of Notes shall be entitled to convert any or all of the
outstanding principal balance of such Notes into Common Stock prior to the
Extended Redemption Date; and (ii) each other date or event that would otherwise
impair any right to convert the Notes into Common Stock or otherwise impair the
rights of the Notes shall be tolled until the Extended Redemption Date.  Any
Holder of Notes who is required to comply with the filing and waiting period
requirements of the HSR Act with respect to the conversion of any Notes shall
use commercially reasonable efforts to cause such filing to be made as soon as
practicable after such Holder has provided notice of its intention to convert
such Notes and to diligently and in good faith pursue expiration or termination
of the waiting period of the HSR Act, provided no conditions are imposed on
Sprint.


                                  ARTICLE IV

                              ADVANCE CONDITIONS

     Sprint shall not be required to make a requested Advance, if on the
proposed Borrowing Date for such Advance:

          (b)  All representations and warranties of the Borrowers contained
     herein are not true and correct (i) as of the date referred to in any
     representation or warranty that addresses a matter as of a particular date
     and (ii) as to all other representations and warranties as of the date of
     such proposed Advance, unless, in either the case of clause (i) or (ii),
     the inaccuracy of such representations and warranties would not,
     individually or in the aggregate, have a Material Adverse Effect;

                                       21
<PAGE>
 
          (c)  The Average Market Price of the Newco Common Stock is less than
     $13.00 (adjusted after the date hereof for any stock split, stock dividend
     or other subdivision or combination of the Newco Common Stock);

          (d)  A Borrowing Notice shall not have been properly submitted with
     respect to such Advance;

          (e)  A duly executed Note representing the Advance has not been
     received by Sprint;

          (f)  The Facility Termination Date shall have occurred; or

          (g)  A Default or Event of Default has occurred and is continuing or

     specifically disclosed to Sprint in the Borrowing Notice for such Advance
     and as to which Sprint has, within five (5) Business Days after Sprint's
     receipt of the Borrowing Notice, neither advised the Borrowers of its
     intent to declare an Event of Default nor, advised the Borrowers that it
     intends to exercise its rights in this clause (g) and not make the
     requested Advance (as is Sprint's right, exercising such right in its sole
     discretion).

Each Borrowing Notice with respect to each such Advance shall constitute a
representation and warranty by  the Borrowers that the conditions contained in
this Article IV have been satisfied. Sprint may require a duly completed
compliance certificate (dated the Borrowing Date) in substantially the form of
Exhibit B hereto as a condition to making an Advance.

     SECTION 5.02.  Subsidiaries and Joint Ventures. No Borrower has any
Subsidiary that is not also a Borrower hereunder or has the right to acquire an

enforcement thereof may be limited by (i) bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally, and (ii) general principles of equity
regardless of whether enforceability is considered in a proceeding in equity or
at law. The execution and delivery of this Agreement by each Borrower did not,

notice or lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or to loss by such Borrower of a
material benefit under, or result in the creation of any Lien upon any of the
properties or assets of such Borrower under, (i) the certificate of
incorporation or bylaws of such Borrower, (ii) any loan or credit agreement,

the ability of such Borrower to perform its obligations under this Agreement or
(z) prevent the consummation of any of the transactions contemplated by this
Agreement.

     SECTION 5.04.  Taxes. Except as set forth on Schedule 5.04, each Borrower
has timely filed all Returns and reports required to be filed by it, except
where failure to timely file would not have a Material Adverse Effect. All such
Returns and reports are complete and accurate except where the failure to be
complete or accurate would not have a Material Adverse Effect. Each Borrower has
paid or has set up an adequate reserve for the payment of all Taxes shown as due
on such Returns except where the failure to do so would not have a Material
Adverse Effect. Except as set forth on Schedule 5.04, no deficiencies for any
Taxes have been asserted, proposed or assessed against any Borrower that have
not been paid or otherwise settled or reserved against, except for deficiencies
the assertion, proposing or assessment of which would not have a Material
Adverse Effect, and no requests for waivers of the time to assess any such taxes
are pending. There are no material Liens for Taxes (other than for current taxes
not yet due and payable) on the assets of any Borrower.

     SECTION 5.05.  Compliance with Laws. Each Borrower has in effect all
permits from approvals, authorizations, certificates, filings, franchises,
licenses, notices, permits, variances, exemptions, orders and rights ("Permits")

been in full compliance with, and has not been and is not in violation of or
liable under, any Environmental Law (which compliance includes the possession by
such Borrower of all Permits required under applicable Environmental Law and
compliance with the terms and conditions thereof), except for such failure to be
in compliance which, individually or in the aggregate, would not have a Material
Adverse Effect. There are no pending or, to the Knowledge of any Borrower,
Threatened claims, orders, notices, administrative or judicial actions, or
Encumbrances, relating to environmental, health, and safety liabilities arising
under or pursuant to any federal, state or local Environmental Laws, with
respect to or affecting any of the properties and assets (whether real,
personal, or mixed) in which such Borrower has an interest, except for any such
claim, order, notice, administrative or judicial action, Encumbrance or other
restriction that would not, individually or in the aggregate, have a Material
Adverse Effect.

     SECTION 5.07.  Intellectual Property. Each Borrower owns sufficient right,
title and interest in and to, or has valid licenses of sufficient scope and
duration for, all patents, patent rights, copyrights, trademarks, service marks,
trade names, software, trade secrets, confidential information and other
intellectual property material to the operation of the business of such Borrower
as currently conducted or proposed to be conducted (the "Intellectual Property
Assets") and as proposed to be conducted. The Intellectual Property Assets are
free and clear of all Liens which would materially impair such Borrower's
ability to use the Intellectual Property Assets in the business of such Borrower
as currently conducted or proposed to be conducted. No Borrower has granted any
third party any rights in and to the Intellectual Property Assets except for
distribution rights, OEM rights, end user licenses and rights to reproduce
certain of the Intellectual Property Assets in the Ordinary Course of Business
in connection with the marketing and distribution of such Borrower's product and
service offerings, and which individually and in the aggregate would not have a
Material Adverse Effect. Except as set forth on Schedule 5.8, no Intellectual
Property Assets of any Borrower infringes, or conflicts with, or to the
Knowledge of any Borrower, is alleged to infringe upon or conflict with the
intellectual property rights of any third party. No Borrower has Knowledge that
any of its employees performing or managing key functions of such Borrower is
obligated under any contract (including licenses, covenants or commitments of
any nature) or other agreement, or subject to any judgment, decree or order of
any court or administrative agency, that would interfere with the use of such
employee's best efforts to promote the interests of such Borrower or that would
conflict with such Borrower's business as proposed to be conducted. To the
Knowledge of any Borrower, neither the execution nor delivery of this Agreement,
nor the carrying on of any Borrower's business by the employees of such
Borrower, nor the conduct of the business of any Borrower as proposed, will
conflict with or result in a breach of the terms, conditions or provisions of,
or constitute a default under, any contract, covenant or instrument under which
any of such employees is now obligated, which conflict or breach would have a
Material Adverse Effect. No Borrower utilizes or intends to 

                                       24
<PAGE>
 
utilize any inventions of any of its employees (or people it currently intends
to hire) made prior to their employment by such Borrower.

Borrower, has directly or indirectly (a) made any contribution, gift, bribe,
rebate, payoff, influence payment, kickback, or other payment to any Person,
private or public, regardless of form, whether in money, property, or services

favorable treatment for business secured, (iii) to obtain special concessions or

     In addition to, and without limitation of, any rights of Sprint under
applicable law, if any Default or Event of Default or Business Combination
occurs, any and all deposits (including all account balances, whether
provisional or final and whether or not collected or available) and any other
Indebtedness at any time held or owing by Sprint or any Affiliate of Sprint to
or for the credit or account of any Borrower may be offset and applied toward
the payment of the Obligations owing to Sprint or such Affiliate of Sprint,
whether or not the Obligations, or any part hereof, shall then be due or have
matured; provided, however, the foregoing shall not apply to any Business
Combination unless at least ten days prior to such offset or applications,
Sprint has given notice to the Borrowers that a prepayment is being required
under Section 3.08(a).

                       BENEFIT OF AGREEMENT; ASSIGNMENTS

     SECTION 10.01.  Successors and Assigns. The terms and provisions of the
Loan Documents shall be binding upon and inure to the benefit of the Borrowers
and Sprint and their respective successors and assigns, except that (a) the
Borrowers shall not have the right to assign any rights or obligations under the
Loan Documents, and (b) any assignment by Sprint must be made in compliance with
Section 10.02.  Any assignee or transferee of any Note agrees by acceptance
- - -------------                                                              
thereof to be bound by all the terms and provisions of the Loan Documents.  Any
request, authority or consent of any Person, who at the time of making such
request or giving such authority or consent is the holder of the Note, shall be
conclusive and binding on any subsequent holder, transferee or assignee of such
Note or of any note or notes issued in exchange therefor.

     SECTION 10.02.  Assignments by Sprint.

          10.02.1.   Assignments of this Agreement and the Obligations
                     -------------------------------------------------
Thereunder.  An Assignment or transfer of this Agreement may be made without the
- - ----------
prior consent of the Borrowers (i) by Sprint to any of its Affiliates, provided
that any such assignment or transfer to such Affiliate shall not release Sprint
from the obligations of Sprint under this Agreement, or (ii) pursuant to any
merger or sale of substantially all of the assets or stock of Sprint or such
Affiliates (or any transaction having such effect) that is pursuant to an
agreement entered into after the Closing Date and pursuant to which in the case
of a purchase of substantially all of the assets or stock of Sprint or such
Affiliates, the party purchasing such assets or stock of Sprint or such
Affiliates assumes the obligations of Sprint under this Agreement.

          10.02.2.   Transfers of the Notes.  Sprint may in accordance with
                     ----------------------                                
applicable law and without the prior consent of the Borrowers, at any time,
transfer and assign all or part of the Notes to one or more Persons
("Transferees").  In the case of such an assignment or transfer, Sprint shall
surrender the Notes subject to such assignment to the Borrowers prior to the
transfer and assignment being effective and the Borrowers shall, simultaneously
with such surrender, reissue and deliver new Notes in the same aggregate
outstanding principal amount as the surrendered Note in the name of such holders
as requested by Sprint.  On or after the effective date of such transfer and
assignment, (a) each such Transferee shall acquire all of the rights of Sprint
in the Notes assigned to such Transferee, and (b) Sprint shall remain subject to
the Aggregate Commitment and Loans.

          10.02.3.   Administration.  As a condition to any transfer or
                     --------------                                    
assignment of the Notes pursuant to Section 10.02.2, each Transferee shall
appoint Sprint (or any other Person to whom this Agreement has been assigned in
accordance with Section 10.02.1 or with the consent of the Borrowers) (the
"Agent") to act as agent of such Transferee, provided that the Agent shall not
have a fiduciary relationship in respect of the Borrowers or any Transferee of
the Notes.  The Agent shall exclusively exercise such powers under this
Agreement as are specifically delegated to Sprint by the terms hereof, including
the right to receive notices, requests, waivers, instructions, information

                                       35
<PAGE>
 
regarding the Borrowers, consents and other documents which the Borrowers may be
required to deliver pursuant to this Agreement.  The Agent shall have no implied
duties to the Transferees, or any obligation to the Transferees to take any
action thereunder.

     SECTION 10.03.  Dissemination of Information. Each Borrower authorizes
Sprint to disclose to any Person to whom this Agreement is being assigned
pursuant to Section 10.02.1 or Transferees under Section 10.02.2 any and all
information in Sprint's possession concerning the creditworthiness of the
Borrowers, subject however, to Sprint obtaining an appropriate confidentiality
agreement respecting such information.

                   [DEUTSCHE MORGAN GRENFELL LETTERHEAD]




February 10, 1998


Board of Directors
EarthLink Network, Inc.
3100 New York Drive
Pasadena, CA 91107


Members of the Board:

    We understand that Dolphin Sub,Inc. ("Newco Sub"), a wholly-owned 
subsidiary of Dolphin, Inc. ("Newco") EarthLink Network, Inc. ("EarthLink" or 
the "Company"), Sprint Corporation ("Sprint"), and its indirect subsidiary 
Sprint Communications Company L.P. ("Sprint L.P."), propose to enter into an 
Investment Agreement dated as of the date hereof (the "Investment 
Agreement"), which provides, among other things, for the commencement by 
Sprint of a tender offer (the "Offer") to purchase 1,250,000 shares of common 
stock, par value $0.01 per share, of the Company ("the Common Stock")  for an 
aggregate cash consideration of $56,250,000 and at a price per share of 
Common Stock of $45 net to the seller in cash (such shares representing 
approximately 11% of the shares of Common Stock outstanding on the date 
hereof). Unless otherwise defined herein, capitalized terms used herein shall 
have the meanings ascribed thereto in the Investment Agreement.

    Immediately following the closing of the Offer (the "Closing"), Sprint 
L.P. will purchase 4,102,941 shares of Series A Convertible Preferred Stock, 
par value $.01 per share, of Newco (the "Convertible Preferred Stock"), in 
exchange for (i) aggregate cash consideration of $23,750,000, (ii) the 
assignment to Newco of 100% of the SIP Subscribers, and (iii) entering into a 
network agreement whereby Newco and the Company will utilize Sprint's 
long-distance network under specified terms and conditions. The assets listed 
in Clauses (ii) and (iii) of the preceding sentence are herein referred to as 
the "Contribution Assets".

    We also understand that the closing of the purchase and sale of the 
Convertible Preferred Stock shall take place immediately following the 
closing of the Offer and concurrently with the merger of Newco Sub into the 
Company (the "Merger") and the conversion of each share of Common Stock into 
one share of Newco common stock par value of $0.01 per share, pursuant to the 
Merger. The Offer,the sale of the Convertible Preferred Stock and the Merger 
are collectively referred to herein as the "Transactions". The terms and 
conditions of the Transactions are more fully set forth in the Investment 
Agreement.

    We further understand that Newco Sub, Newco, the Company, Sprint and 
Sprint L.P., as applicable, have entered into certain other agreements 
including the Certificate of Designation, the Governance Agreement, the 
Master Assignment, the Marketing Agreement, the Network Services Agreement, 
the Registration Rights Agreement, the Credit Agreement, the Stockholders 
Agreement, the Agreement and Plan of Merger, the Agreement to Vote and the 
Agreement to Vote and Tender (collectively, the "Ancillary Agreements") and 
that stockholders owning more than 1,250,000 shares of the Common Stock have 
agreed to tender their shares to Sprint in connection with the Offer pursuant 
to the Agreement to Vote and Tender (the "Tendering Stockholders"). As a 
result, no stockholder of EarthLink other than the Tendering Stockholders is 
required to tender shares of the Common Stock in


<PAGE>

order for the Offer to be completed.

    You have asked for our opinion as to whether the Transactions, when taken 
together, are fair from a financial point of view to the holders of the 
Common Stock.

              For purposes of the opinion set forth herein, we have:

    (i)       analyzed certain publicly available financial statements and other
              information concerning Sprint and the Company, respectively;

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

    (iii)     analyzed certain financial projections relating to the Company 
              prepared by the management of the Company;

    (iv)      discussed the past and current operations and financial 
              condition and the prospects of the Company with senior 
              executives of the Company;

    (v)       discussed the financial value of the Contribution Assets with 
              the management of the Company and the nature of the 
              Contribution Assets with the management of Sprint;

    (vi)      analyzed the pro forma impact of the Transactions on the 
              revenue, operating cash flow, consolidated capitalization and 
              other financial ratios of the Company;

    (vii)     reviewed the reported prices and trading activity for the 
              Common Stock;

    (viii)    compared the financial performance of the Common Stock and the 
              prices and trading activity of the Common Stock with that of 
              certain other comparable publicly-traded companies and their 
              securities;

    (ix)      compared the results of operations of the Company with that of 
              certain companies which we deemed to be reasonably similar to 
              the Company.

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

    (xi)      discussed, with the management of the Company, the strategic 
              rationale and certain other benefits to the Company of the 
              Transactions;

    (xii)     participated in discussions and negotiations among 
              representatives of the Company and Sprint and their financial 
              and legal advisors;

    (xiii)    reviewed the Investment Agreement and the Ancillary Agreements; 
              and

    (xiv)     performed such other analyses as we have deemed appropriate.

    We have assumed and relied upon, without independent verification, the 
accuracy and completeness of the information reviewed by us for the purposes 
of this opinion. With respect to the financial projections, we have assumed 
that they have been reasonably prepared on bases reflecting the best 
currently available estimates and judgments of the future financial 
performance of  


<PAGE>

the Company. We have also relied upon, without independent verification, the 
assessment by the Company's management of the strategic and other benefits 
expected to be derived from the Transactions. We have not made any 
independent valuation or appraisal of the assets, liabilities or technology 
of the Company, or of the Contribution Assets, nor have we been furnished 
with any such appraisals. Our opinion is necessarily based on the economic, 
market and other conditions as in effect on, and the information made 
available to us as of, the date hereof. We have also taken into account that 
because the Tendering Stockholders, who collectively own more than 1,250,000 
shares of the outstanding Common Stock, have agreed to facilitate the 
transaction by tendering their shares to Sprint in connection with the Offer, 
such that the Offer will be consummated regardless of whether any other 
stockholders of the Company elect to tender their shares into the Offer.

     In the course of our assignment in connection with the Transactions we 
have had discussions (and are aware that management of the Company has had 
discussions) with several parties concerning a possible transaction, business 
combination, or strategic alliance including all or any part of the company. 

     We have acted as financial advisor to the Board of Directors of the 
Company in connection with this transaction and will receive a fee for our 
services.  In addition, in the ordinary course of our business, we may 
actively trade the securities and loans of both the Company and Spring for our 
own account and for the accounts of our customers and, accordingly, may at 
any time hold a long or short position in such securities and loans. 

     It is understood that this letter is for the information of the Board of 
Directors of the Company only and may not be used for any other purpose 
without our prior written consent, except that this opinion may be included 
in its entirety in any documents filed by the Company with the Securities and 
Exchange Commission with respect to the Transactions. In addition, we express 
no recommendation or opinion to the holders of the Common Stock as to whether 
or not to tender shares of Common Stock pursuant to the Offer or as to how 
the stockholders of the company should vote at the stockholders meeting to be 
held in connection with the Transactions.

     Based on and subject to the foregoing, we are of the opinion on the date 
hereof that the Transactions, when taken together, are fair from a financial 
point of view to the holders of the Common Stock. 

                                             Very truly yours,

                                             DEUTSCHE MORGAN GRENFELL INC.

                                   Definitions

                  SECTION 1.01. Definitions. As used in this Agreement, the
following terms shall have the following meanings:

                  "Acquisition Proposal" means any proposal for a tender or
exchange offer, a merger, consolidation, share exchange or other business

acquisition of beneficial ownership of 20% or more of the Voting Equity
Securities of Newco being deemed to be material for this purpose) or assets of,
Newco, other than the transactions contemplated by this Agreement with respect
to Affiliated Equity Holders effected in accordance with this Agreement. A
Material Sale will constitute an Acquisition Proposal.

Investment Agreement.

                  "Affiliated Equity Holders" means Sprint, Sprint L.P. and any

Equity Securities.

                  "Alternative Securities" means a new series of Preferred Stock
having terms that are structured and priced in the same manner as the terms of
the Series A Stock (including, without limitation, date of allowable optional
redemption, dividend rate, liquidation value, redemption value, conversion
premium and conversion rate), provided, that, all of such terms are determined,
if applicable, by reference to the Average Stock Price for the 30 trading days
prior to the date of issuance of such Alternative Securities.

                  "Ancillary Agreements" has the meaning assigned to such term
in the Investment Agreement, but for purposes of this Agreement shall also

under the Exchange Act.

Transaction Securities, the number of shares of Common Stock underlying Equity
Securities that Sprint may purchase from Newco pursuant to Section 3.01(d)
hereof following an issuance of Transaction Securities, determined as follows:

where x equals the number of Transaction Securities issued in such transaction
and SPI equals Sprint's Percentage Interest expressed as a decimal carried to
the third place. As permitted in Section 3.01(e) hereof, Available Top-Up Shares
may, at Sprint's discretion, to the extent indicated in such section, be in the
form of shares of Newco Common Stock or Alternative Securities convertible into
an equivalent number of shares of Newco Common Stock.

         Associates, directly or indirectly, has the right to acquire (whether
         such right is exercisable immediately or only after the passage of
         time) pursuant to any agreement, arrangement or



                                       3

         conversion rights, exchange rights, rights, warrants, options or
         otherwise;

                   (b) which such Person or any such Person's Affiliates or

         Agreement), including pursuant to any agreement, arrangement or
         understanding, whether or not in writing; provided, however, that a
         Person shall not be deemed the "Beneficial Owner" of, or to
         "beneficially own," any security under this subparagraph (b) as a
         result of an agreement, arrangement or understanding to vote such
         security if such agreement, arrangement or understanding arises solely
         from a revocable proxy given in response to a public proxy or consent

         for the purpose of acquiring, holding, voting (except pursuant to a
         revocable proxy as described in the proviso to subparagraph (b)) or
         disposing of any voting securities of Newco or the Company; provided,
         however, that nothing in this subparagraph (c) shall cause a person
         engaged in business as an underwriter of securities to be the

if the consummation of such transaction would result in the purchaser
beneficially owning 35% or more of the Equity Securities outstanding, or (ii) a
merger, consolidation, combination, share exchange, reorganization or other
extraordinary transaction with respect to Newco in which, upon consummation
thereof, the shareholders or owners of the other entity that is a party thereto,
or the controlling Persons thereof, would acquire beneficial ownership of 50% or
more of the Equity Securities outstanding. A Significant Sale will constitute a
Business Combination. A Business Combination shall not include (A) transactions
contemplated by this Agreement with respect to Affiliated Equity Holders
effected in accordance with this Agreement or (B) any acquisition of beneficial
ownership of Equity Securities resulting from the formation of a "group," as
defined in Rule 13d-5(b) of the Exchange Act, without the occurrence of any

Stock; (y) it shall not be a Discriminatory Transaction for Newco to take action

carried to the third place, by the Dilution Factor; provided, that, if following
such issuance of Transaction Securities, a Primary Share Offer is made by Newco

Sprint or their respective Affiliates or Associates or any other entity such
that a reasonable person would regard such Director as likely to be unduly
influenced by management of Newco, the Company or Sprint, respectively, or their

                  (b) Notwithstanding any provision to the contrary
contained herein, Sprint may effect its rights pursuant to this Section 3.01 by
making purchases of Equity Securities at any time from any Person other than
Newco so long as after giving effect to such purchases, Sprint's Percentage
Interest is less than or equal to the Pro Rata Share.

                  (c) If the Board of Directors proposes to issue New
Securities (other than New Securities that are Transaction Securities) at such
time as Sprint's Percentage Interest is greater than the Top-Up Threshold, Newco
shall provide written notice to Sprint (the "Subscription



                                       16
<PAGE>

Notice") of its intent to effect such issuance at least five business days prior
to the date on which the meeting of the Board is held to authorize the issuance
of such New Securities. The Subscription Notice shall set forth (i) the number
of New Securities proposed to be issued and the terms of such New Securities,
(ii) the consideration (or manner of determining the consideration by reference
to the market price), if any, for which such New Securities are proposed to be
issued and the terms of payment, (iii) the number of New Securities Sprint shall
be entitled to purchase in compliance with the provisions of this Section 3.01
and the purchase price (or manner of determining the consideration by reference
to the market price) and form of consideration therefor and (iv) the proposed
date of issuance of such New Securities. For a period of ten business days after
the receipt by Sprint of the Subscription Notice, Sprint shall have the right to
purchase the Pro Rata Share of such issuance and shall notify Newco in writing,
within such time period whether it elects to purchase all or any portion of the
Equity Securities offered to Sprint pursuant to the Subscription Notice. If
Sprint shall elect to purchase any such New Securities, such securities which it
shall have elected to purchase shall be issued and sold to Sprint by Newco at
the same times and on the same terms and conditions as the New Securities are
issued and sold to third parties (except that, if such New Securities are issued
for consideration other than cash, Sprint shall pay the lower of (x) the same
purchase price per share and other terms, including the same form of
consideration paid by the Purchaser for the New Securities or (y) the fair
market value per share thereof, determined by an independent appraiser mutually
selected by Newco and Sprint), in either case, times the number of shares Sprint
is entitled to purchase; provided, however, that if Sprint's purchase of such
Equity Securities would, in the opinion of its counsel, give rise to the
application of waiting periods under the HSR Act, Sprint shall be obligated to
consummate such purchase as soon as practicable after the applicable waiting
period has elapsed or terminated on an unconditional basis, and Sprint shall,
during such time, diligently and in good faith seek expiration or termination of
the applicable waiting period. If, for any reason, the issuance of New
Securities to third parties is not consummated, Sprint's right to purchase its
Pro Rata Share of such issuance shall lapse, subject to Sprint's ongoing
subscription right with respect to issuances of New Securities at later dates or
times.

                  (d) (i) At such time as Newco, acting in good faith on the
basis of the most recent Sprint Ownership Report provided pursuant to Section
6.02(b) hereof, determines that Sprint's Percentage Interest has decreased by
 .05 or more, after giving effect to any and all Primary Share Offers, solely as
a result of issuances of Transaction Securities, Newco shall promptly notify
Sprint of such event in writing, but in any event not later than the due date of
the next Newco Outstanding Stock Report.

                  (ii) Not later than the second anniversary of Sprint's receipt
of such notice (the "Window Period"), Newco shall be obligated to make written
offers for Sprint to purchase (each, a "Primary Share Offer"), in the aggregate
on the basis of all such Primary Share Offers made in the Window Period, not
less than the sum of the number of Available Top-Up Shares resulting from all
issuances of Transaction Securities that have collectively caused Sprint's
Percentage Interest to have decreased by .05 or more (the "Aggregate Number of
Top-Up Shares") at a purchase price equal to the Average Stock Price for the 10
trading days prior to the date of issuance, less the Underwriting Discount.
Sprint may accept a Primary Share Offer within five business days of its receipt
thereof by giving written notice to Newco of its desire to do so,



                                       17
<PAGE>

specifying (subject to Section 3.01(e) hereof) the number and form of shares of
Equity Securities of Newco Sprint is willing to purchase pursuant to such
Primary Share Offer, and such transaction shall be consummated in accordance
with such notice within three business days of Newco's receipt thereof. The
Aggregate Number of Top-Up Shares will be reduced by the number of shares
offered to Sprint in the Primary Share Offer.

                  (iii) If Newco, acting in good faith on the basis of the most
recent Sprint Ownership Report provided pursuant to Section 6.02(b) hereof,
determines that Sprint's Percentage Interest has decreased by .10 or more solely
as a result of the issuance of Transaction Securities, after giving effect to
any and all Primary Share Offers, Newco shall promptly notify Sprint of such
event in writing, but in any event not later than the due date of the next Newco
Outstanding Stock Report. In such event, the Window Period shall be accelerated
such that Newco shall be obligated to make one or more Primary Share Offers with
respect to not less than the Aggregate Number of Top-Up Shares, as then
calculated, at the earlier of (i) the expiration of the Window Period, as
determined above, or (ii) six months after the date Sprint receives the
foregoing notice from Newco.

                  (iv) Notwithstanding anything contained in this Agreement to
the contrary, in no event whatsoever shall Newco be obligated to make Sprint a
Primary Share Offer that, after giving effect to such transaction, would cause
Sprint's Percentage Interest to exceed the Pro Rata Share.

                  (e) In respect of a purchase of New Securities pursuant to
Section 3.01(c) or 3.01(d) hereof, Sprint may, at its option, by notice given to
Newco at the time Sprint provides notice of its intention to purchase New
Securities pursuant to either of such sections, acquire such shares in the form
of Alternative Securities (to the extent set forth below) convertible into the
applicable number of shares of Newco Common Stock, assuming the acceleration of
the full amount of any liquidation accretion dividends with respect to such
Alternative Securities, consistent with the acceleration contemplated by the
last sentence of Section 3(a)(i) of the Certificate of Designation. Sprint's
purchase of New Securities in the form of Alternative Securities shall be
limited as follows:

                  (i) From the Closing to the second anniversary thereof, Sprint
                  may purchase not more than 75% of any issuance of New
                  Securities in the form of Alternative Securities;

                  (ii) After the second anniversary of the Closing until the
                  third anniversary thereof, Sprint may purchase not more than
                  66.67% of any issuance of New Securities in the form of
                  Alternative Securities; and

                  (iii) After the third anniversary of the Closing, Newco shall
                  have no obligation to issue New Securities in the form of
                  Alternative Securities.

                  SECTION 3.02. Issuance and Delivery of New Securities and
Voting Equity Securities. Newco represents, warrants and covenants to Sprint
that (i) upon issuance, all of the shares of New Securities or Alternative
Securities sold to Sprint pursuant to this Article III shall



                                       18
<PAGE>

be duly authorized, validly issued, fully paid and nonassessable and will be
approved (if outstanding securities of Newco of the same type are at the time
already approved) for quotation on the Nasdaq National Market or for quotation
or listing on the principal trading market for the securities of Newco at the
time of issuance and (ii) upon delivery of such shares, such shares shall be
free and clear of all claims, liens, encumbrances, security interests and
charges of any nature and shall not be subject to any preemptive right of any
stockholder of Newco or any other rights to purchase or vote such shares or any
power of attorney with respect thereto, except as may be set forth in this
Agreement and the Investment Agreement. Each share issued or delivered by Newco
hereunder shall bear the legend set forth in Section 3.03 of the Investment
Agreement.

                                   ARTICLE IV

        Purchases of Additional Equity Securities; Business Combinations

                  SECTION 4.01. General Standstill Obligations. Subject to the
following provisions and except for (i) purchases of shares made by Sprint
permitted under the provisions of Section 3.01, or (ii) offers, purchases and
other matters effected by Sprint in accordance with the provisions of Section
4.02 or Section 4.03 hereof, none of the Affiliated Equity Holders will, nor
will any Affiliated Equity Holders authorize any of their agents or
representatives to, without prior written consent of the Board of Directors of
Newco, directly or indirectly, acting alone or in concert with other Persons:

                  (a) acquire, offer to acquire, or agree to acquire, directly
or indirectly, by purchase or otherwise, any Equity Securities or direct or
indirect rights to acquire any Equity Securities, or any equity securities of
any Subsidiary of Newco, material assets of Newco or any Subsidiary or division
of Newco or of any successor or controlling Person of any of the foregoing,
except for its right to convert Series A Stock, Alternative Securities, the
Convertible Notes or other Equity Securities, and to receive stock dividends,
stock splits and other distributions of Equity Securities;

                  (b) make, or in any way participate, directly or indirectly,
in any "solicitation" of proxies to vote (as such terms are used in the rules of
the SEC), or seek to advise or influence any person or entity with respect to
the voting of any Voting Equity Securities of Newco, except for any solicitation
of proxies to vote or related communications made in response to a proxy contest
by a third party in connection with offers made by Sprint in accordance with
Section 4.02 or Section 4.03 hereof;

                  (c) make any public announcement with respect to, or submit a
proposal for, or offer to effect (with or without conditions) any purchase of a
significant portion of the assets of Newco or any Subsidiary or division of
Newco, any tender or exchange offer for any of the Equity Securities of Newco or
a merger, consolidation, combination, share exchange, reorganization or other
extraordinary transaction involving Newco or any of its Equity Securities or
assets or any Subsidiary of Newco or any of such Subsidiary's equity securities
or assets, or otherwise make any Acquisition Proposal, except for any
announcement required in connection with Section 4.02 or Section 4.03 hereof;



                                       19
<PAGE>

                  (d) form, join or in any way participate in a "group" as
defined in Rule 13d-5(b) under the Exchange Act in connection with any of the
foregoing, except as contemplated by any Ancillary Agreement; or

                  (e) request Newco or any of its representatives, directly or
indirectly, to amend or waive any provision of this Section 4.01.

                  Sprint will promptly advise Newco of any inquiry or proposal
made to it with respect to any of the foregoing and describe, in reasonable
detail, the terms and conditions thereof.

                  Notwithstanding any other provision of this Agreement to the
contrary, in the event that, following termination of this Agreement pursuant to
Section 7.01 hereof, but at such time as Sprint shall still be subject to this
Section 4.01, Newco receives either (i) a Recommended Third-Party Offer or (ii)
a Non-Recommended Third-Party Offer, which the Board of Directors of Sprint
reasonably determines in good faith upon consultation with independent legal
counsel and its outside financial advisors is reasonably likely to be
consummated, Sprint shall be temporarily released from its obligations under
this Section 4.01 insofar as necessary to permit Sprint to present an offer
directly to the Board of Directors. Such release shall survive for so long as
such Third-Party Offer remains outstanding or is consummated or abandoned.

                  If any agent or representative of an Affiliated Equity Holder
shall violate any provision of this Section 4.01 by purchasing Equity Securities
for the account of any Affiliated Equity Holder or take any other action in
violation of this Section 4.01 for or on behalf of any Affiliated Equity Holder,
each Affiliated Equity Holder shall, within 14 days of becoming aware of such
violation, take such action as is necessary to remedy such violation, including
selling all Equity Securities purchased in violation of this Section 4.01, and,
upon effecting such remedy, such violation shall not be deemed to be a breach of
this Agreement.

                  SECTION 4.02. Sprint Right to Offer. (a) Following the
39-month anniversary of Closing and prior to the 63-month anniversary of Closing
(such period, the "Right to Offer Period"), Sprint shall have the right to offer
to purchase all, but not less than all, of the outstanding Equity Securities
that it does not already own at a per share price equal to the per share price
determined by dividing the Fair Private Market Value by the total number of
shares of Newco Common Stock outstanding on a Fully-Diluted Basis. The Fair
Private Market Value shall be determined in accordance with Section 4.02(b).
During any time in which Sprint shall be permitted to make an offer under this
Section 4.02(a), Newco shall make available to Sprint such information regarding
the business, properties, assets, condition (financial or otherwise) or results
of operations of Newco, the Company and their Significant Subsidiaries
reasonably requested by Sprint, subject to Sprint entering into a customary
confidentiality agreement with respect to all such information.

                  (b) (i) In the event Sprint wishes to exercise its right to
offer with respect to all, but not less than all, of the outstanding Equity
Securities that it does not already own, as set forth in Section 4.02(a) hereof,
Sprint shall approach the Board of Directors with an offer in


                                       20

<PAGE>

writing (the "Sprint Offer"), which shall include the price per share Sprint is
willing to pay based on the definition of Fair Private Market Value and describe
in reasonable detail such other terms and conditions of the Sprint Offer. A
Sprint Offer shall not be subject to any financing contingency. A Sprint Offer
shall be reflected in a form of definitive agreement which Sprint is prepared to
execute. The conditions to consummation of the Sprint Offer and the
representations and warranties set forth in the Sprint Offer shall be reasonable
and customary for transactions in which a similarly situated stockholder offers
to purchase all of the Equity Securities not held by such stockholder or its
Affiliates.

                  (ii) The Board of Directors of Newco shall have a one-time
right, exercisable by written notice to Sprint given within 14 days after the
receipt of the Sprint Offer, to postpone the making of that offer for nine
months (the "Postponement Right"); provided, that, the Board of Directors may
not exercise the Postponement Right in connection with a Sprint Offer made
pursuant to Section 4.03(b) or Section 4.04(b) hereof. Upon exercise of the
Postponement Right, Sprint shall withdraw the Sprint Offer, in which case it may
not exercise its right to offer under this Section 4.02 for a period of nine
months following the date of exercise of the Postponement Right; provided,
however, that (A) in that event, the Right to Offer Period shall be extended to
the 72-month anniversary of Closing and (B) the Postponement Right shall not
limit Sprint's right to respond to a Third-Party Offer as set forth in Section
4.03 hereof.

                  (iii) The Board of Directors of Newco and Sprint shall
negotiate the amount of the Fair Private Market Value to be paid pursuant to the
Sprint Offer in good faith and Sprint shall not make any public announcements
relating to this offer without the prior written consent of the Board unless
required by law or legal process. In the event the two parties are unable to
agree on the amount of the Fair Private Market Value within 30 days after
submission of the Sprint Offer to the Board, the parties shall agree to be bound
to the valuation arrived at pursuant to the following formula:

                                    (A) Two appraisals shall be made by
                  recognized investment banks, one selected by each of Sprint
                  and Newco (the "Initial Values");

                                    (B) If the lower of the Initial Values is
                  more than 10% less than the higher of the Initial Values, a
                  third independent valuation will be made by an investment bank
                  selected jointly by Sprint and Newco (the "Independent
                  Valuation"). Otherwise, the Fair Private Market Value shall be
                  the average of the Initial Values; and

                                    (C) If the Independent Valuation is greater
                  than or less than the average of the Initial Values by more
                  than 5%, the Fair Private Market Value shall be deemed to
                  equal the average of the two closest valuations. If the
                  Independent Valuation does not differ by such amount, the
                  Independent Valuation shall be the Fair Private Market Value.

                  (c) Upon the determination of the amount of the Fair Private
Market Value, Sprint shall be obligated to commence and effectuate the Sprint
Offer, provided, however, that Sprint shall have a one-time right ("Walk-Away
Right"), exercisable by written notice to Newco


                                       21

<PAGE>

given within 14 days after the receipt of the determination of Fair Private
Market Value, to determine not to proceed to make such Sprint Offer; provided,
further, however, that Sprint may not exercise the Walk-Away Right in connection
with a Sprint Offer made pursuant to Section 4.03(b) or Section 4.04(b) hereof.
If Sprint does not exercise such Walk-Away Right, the Board of Directors shall,
if an Intervening Offer is not then outstanding, i)" (i) support the Sprint
Offer by approving and recommending it to Newco stockholders and ii)" (ii) cause
Newco to take all steps reasonable and necessary to facilitate consummation of
such Sprint Offer. If Sprint exercises such Walk-Away Right, all Affiliated
Equity Holders, Newco, the Company and all of their officers, directors,
employees, representatives and agents shall be obligated to protect and hold in
strict confidence the amount of the Fair Private Market Value determined as set
forth above unless disclosure thereof is required by law or legal process.

              (d) [Reserved.]

              (e) (i) At such time as a Third-Party Offer shall constitute
an Intervening Offer, (A) Sprint shall be released from its obligation to
commence and effectuate the Sprint Offer, and (B) Newco shall be released from
its obligation to support and facilitate consummation of the Sprint Offer.
Notwithstanding the foregoing, Sprint shall be entitled, at any time prior to
consummation of the Intervening Offer, to make a Qualified Offer. In such event,
the most recent Third-Party Offer shall cease to constitute an Intervening
Offer.

                  (ii) If an Intervening Offer is undertaken, in whole or in
part, in the form of a tender offer, at the consummation of such tender offer,
the offeror shall have an option, exercisable for a period of 20 days following
the consummation of such tender offer, to purchase from all Affiliated Equity
Holders, at the tender offer price, in the aggregate, the Specified Number of
Equity Securities less the number of Equity Securities that have already been
tendered by the Affiliated Equity Holders.

                  (iii) If, in the event of an Intervening Offer, such offer, a
Business Combination underlying such offer or any related matter that must be
approved by the stockholders of Newco in order for such offer to be effectuated
is brought before the stockholders of Newco for their consideration and
approval, Sprint and Sprint L.P. shall be obligated, in the event a Qualified
Offer has not been made within five days prior to the date of the stockholders'
meeting, to cast (or to cause to be cast by their Affiliated Equity Holders) in
favor of the Intervening Offer, the Business Combination or any such related
matter such number of votes as is equal to the Specified Number of Equity
Securities, provided, that, such Business Combination does not constitute a
Discriminatory Transaction.

              (f) None of the Affiliated Equity Holders shall be entitled to
exercise rights of appraisal under Section 262 of the Delaware General
Corporation Law (or any successor thereto) as to any of the Equity Securities
owned by them in respect of any Business Combination effected in connection with
an Intervening Offer.

              SECTION 4.03. Third-Party Offers. (a) Newco shall promptly
provide to Sprint written notice (the "Offer Notice") of its receipt of an Offer
and, in reasonable detail, the proposed terms thereof. Upon receipt of such
Offer, the Board of Directors shall determine that:


                                       22

<PAGE>

                  (i) such Offer is in the best interests of Newco's
stockholders and that it intends to recommend such Offer to the stockholders (a
"Recommended Third-Party Offer");

                  (ii) such Offer is not in the best interests of Newco's
stockholders and that it intends not to recommend such Offer to the stockholders
or no position is taken with respect thereto under Rule 14e-2 of the Exchange
Act within 10 business days of the Board's receipt thereof (a "Non-Recommended
Third-Party Offer" and, together with a Recommended Third-Party Offer, a
"Third-Party Offer"); or

                  (iii) insufficient information exists on which to base any
such recommendation, in which event the Board may take such action as it deems
necessary or advisable to develop such additional information; provided, that,
if upon developing such additional information, the Board decides to recommend
or not to recommend such Offer to the stockholders, then it shall promptly
notify Sprint of such decision and, at such time, the Offer shall be deemed a
Recommended Third-Party Offer or a Non-Recommended Third-Party Offer, as
appropriate.

             (b) For a period of ten days following the giving of the Offer
Notice, Newco may not enter into a definitive agreement with respect to the
Offer. Upon receipt of such Offer Notice, Sprint shall be released from its
obligations under Section 4.01 insofar as necessary to permit Sprint, subject to
the terms and conditions of this Agreement and if an Intervening Offer is not
then outstanding, to make, pursue and consummate a Sprint Offer. However, Newco
shall not be obligated to deem a bona fide, written offer from any Person other
than an Affiliated Equity Holder to effect a Business Combination to be an Offer
and to provide the Offer Notice required by Section 4.03(a) until the earlier of
(i) the date on which Newco determines that such offer meets the requirements of
an Offer and that Newco intends to pursue such Offer with the objective of
having it become a Recommended Third-Party Offer, or (ii) ten days after the
date Newco receives such offer, unless previously rejected by Newco.

              (c) In the case of an Offer that is a Recommended Third-Party
Offer, Sprint shall have the option to make a Qualified Offer, and Newco shall
not adopt any takeover defenses (unless amended or waived to permit Sprint to
make a Qualified Offer), enter into any agreement or take any other action if
such action would, in either case, materially impair Sprint's ability to make
and consummate a Qualified Offer or materially increase Sprint's costs of
consummating such Qualified Offer; provided, however, that, notwithstanding the
foregoing, Newco shall be permitted to enter into a definitive agreement with
respect to a Recommended Third-Party Offer that provides for a termination fee
not to exceed 3% of the consideration to be received per share of Newco Common
Stock multiplied by the number of shares of Newco Common Stock outstanding on a
Fully-Diluted Basis (less the number of shares beneficially owned by the
offering party), plus customary fees and expenses, except that the definitive
agreement with respect to such Recommended Third-Party Offer shall provide that
such fee shall not be payable by Sprint if it makes a Qualified Offer within 72
hours of the first public announcement of such Recommended Third-Party Offer
(provided, that, there are at least two business days within such period). In
the case of an Offer that is a Non-Recommended Third-Party Offer, Sprint shall
have the option to make a Qualified Offer, but only if the Board of Directors of
Sprint reasonably determines in good faith upon consultation with independent
legal


                                       23

<PAGE>

counsel and its outside financial advisors that the conditions to the
Non-Recommended Third-Party Offer are reasonably likely to be satisfied and the
offer consummated.

              If Sprint has the option to make a Qualified Offer and does so
more than five days prior to the date of a stockholders meeting held to consider
a Third-Party Offer or an Intervening Offer, the Board of Directors shall, if an
Intervening Offer is not then outstanding, (i) support the Qualified Offer by
approving and recommending it to Newco's stockholders and (ii) cause Newco to
take all steps reasonable and necessary to facilitate the consummation of the
Qualified Offer.

              (d) (i) At such time as a Third-Party Offer made subsequent to
a Qualified Offer shall constitute an Intervening Offer, Newco's obligations to
support and facilitate a Qualified Offer as set forth in Section 4.03(c) above
shall terminate and Newco shall be free to consider and act upon such
Intervening Offer. Notwithstanding the foregoing, Sprint shall be entitled, at
any time prior to consummation of the Intervening Offer, to make another
Qualified Offer. In the event Sprint makes such Qualified Offer, the most recent
Third-Party Offer shall cease to constitute an Intervening Offer.

                  (ii) If a Recommended Third-Party Offer or an Intervening
Offer, as the case may be, is undertaken, in whole or in part, in the form of a
tender offer, at the consummation of such tender offer, the offeror shall have
an option, exercisable for a period of 20 days following the consummation of
such tender offer, to purchase from any Affiliated Equity Holder, at the tender
offer price, the Specified Number of Equity Securities less the number of Equity
Securities that have already been tendered by the Affiliated Equity Holders.

                  (iii) If, in the event of a Recommended Third-Party Offer or
an Intervening Offer, as the case may be, such offer, a Business Combination
underlying the such offer or any related matter that must be approved by the
stockholders of Newco in order for the offer to be effectuated is brought before
the stockholders of Newco for their consideration and approval, Sprint and
Sprint L.P. shall be obligated, in the event a Qualified Offer has not been made
within five days prior to the date of the stockholders' meeting, to cast (or to
cause to be cast by their Affiliated Equity Holders) in favor of the Recommended
Third-Party Offer or the Intervening Offer, as applicable, the Business
Combination or any such related matter such number of votes as is equal to the
Specified Number of Equity Securities, provided, that, such Business Combination
does not constitute a Discriminatory Transaction.

              (e) None of the Affiliated Equity Holders shall be entitled to
exercise rights of appraisal under Section 262 of the Delaware General
Corporation Law (or any successor thereto) as to any of the Equity Securities
owned by them in respect of any Business Combination effected in connection with
a Recommended Third-Party Offer or an Intervening Offer.

              SECTION 4.04.     Solicitation of Offers.

              (a) From the Closing Date until the earlier of the 27-month
anniversary of Closing or the termination of this Agreement in accordance with
its terms, Newco shall not and shall not authorize or permit any officer,
director or employee of, or any investment banker,


                                       24

any person any information with respect to, or take any other action to expedite
any inquiries or the making of any proposal that constitutes, or may reasonably
be expected to lead to, any Acquisition Proposal; provided, however, that to the
extent required by the fiduciary obligations of the Board of Directors, as
determined in good faith by the Board based on the advice of outside counsel,
Newco may (A) in response to any unsolicited request therefor, furnish
information with respect to Newco or any Subsidiary to any person pursuant to a
customary confidentiality agreement and discuss such information with such
person, (B) upon receipt by Newco of an Acquisition Proposal, following delivery
to Sprint of the notice required pursuant to Section 4.05, participate in
negotiations regarding such Acquisition Proposal, and (C) enter into an
agreement respecting such Acquisition Proposal or enter into any related
agreements or take any other action ancillary thereto, which agreements or
actions are consistent with the requirements of Section 4.03(c) hereof.

earlier of the 39-month anniversary of Closing or the termination of this
Agreement in accordance with its terms, Newco shall not, and shall not authorize
or permit any officer, director or employee of, or any attorney or other advisor
or representative of, Newco or its Affiliates, to take any of the actions
limited by Section 4.04(a) except through an investment banking firm formally
engaged by Newco (or actively working with Newco) for such purpose; provided,
that, 30 days prior to so engaging an investment banking firm for that purpose
or to the commencement of such work, Newco shall notify Sprint of its intention
to effect such engagement or commence such work, and Sprint shall be permitted
to prepare and make a Sprint Offer as defined in Section 4.02(b) hereof for so
long as such investment banking firm remains engaged by, or is working for,
Newco for that specific purpose; provided, that, subject to the terms and
conditions of the Sprint Offer and if an Intervening Offer is not then
outstanding, Sprint will pursue any Sprint Offer made pursuant hereto for so
long as necessary to permit such Sprint Offer to be consummated. Newco shall
furnish Sprint with copies of all information provided by Newco to such
investment banking firm at the time such information is provided to such
investment banking firm, subject to Sprint entering into a customary
confidentiality agreement with respect to such information.

                  (c)      [Reserved.]

                  (d) Nothing contained in this Section 4.04 shall (i) prohibit
Newco from taking and disclosing to its stockholders a position contemplated by
Rule 14e-2 under the Exchange Act or (ii) preclude Newco or the Board from
giving due consideration or responding to any Acquisition Proposal if the
failure to so respond would, in the judgment of the Board of Directors,
exercised in good faith upon the advice of Newco's outside legal counsel, cause
the Board to be in violation of its fiduciary duties to the holders of Equity
Securities.

                  (e) Nothing contained in this Section 4.04 shall adversely
affect Sprint's right to respond to a Third-Party Offer under Section 4.03
hereof, including Sprint's unwillingness to provide a Sprint Offer under Section
4.04(b) above.

action or omit to take an action, and shall cause its Significant Subsidiaries
or any of its or their respective officers, directors, employees,
representatives and agents to take no action or omit to take action, that would
result in (i) any Affiliated Equity Holder being deemed an "acquiring person" or
similar designation under any Stockholders' Rights Plan (commonly known as a
"poison pill") or otherwise being adversely affected by such plan, (ii) any
Affiliated Equity Holder being prejudiced by Newco through its action or its
failure to act under any applicable state takeover statute, including Section
203 of the Delaware General Corporation Law, or (iii) otherwise causing any
takeover defense to materially impair or obstruct, or prevent (either legally or
financially) the exercise by any Affiliated Equity Holder of rights granted
pursuant to this Article IV; provided, however, that (A) Newco may take action
or omit to take action having any such consequence to the extent that such
consequence occurs upon a material breach or violation by any Affiliated Equity
Holder of this Agreement and (B) the execution by Newco, the Company or any
Significant Subsidiary of a definitive agreement in respect of a Business
Combination that is consistent with the requirements of Section 4.03(c) hereof
shall not be deemed to have the effects described in this Section 4.07.

directly or indirectly, sell, transfer or otherwise dispose of any interest in

duly executed and delivered by each of Sprint and Sprint L.P., and constitutes a
valid and binding agreement or irrevocable proxy (coupled with an interest),
respectively, and is enforceable in accordance with its respective terms, except
to the extent that the enforcement of this Agreement or the Irrevocable Proxy
may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or
other similar laws now or hereafter in effect relating to creditors' rights
generally, and (ii) general principles of equity regardless of whether
enforceability is considered in a proceeding in equity or at law.

                  (c) The execution and delivery of this Agreement and of the
Irrevocable Proxy did not, and the performance thereof, without obtaining the
consent of any third party will not,

                  (b) Sprint Ownership Report. Sprint shall provide to
Newco in writing a monthly report setting forth certain information and data
pertaining to the ownership of Equity Securities of Newco by Affiliated Equity
Holders (the "Sprint Ownership Report"), which shall be delivered to Newco on or

delivery to the other party, the submitting party must resubmit a true and
accurate replacement Report which identifies all such corrections; provided,
however, that the submission of any replacement Report or the failure of any
Party to submit such replacement Report shall not constitute a waiver by any
other Party hereto of any substantive rights otherwise existing under this
Agreement.

                                   ARTICLE VII

                                  Miscellaneous

Agreement of registration rights (demand or incidental) held by Person
thereunder.

                  (b) Notwithstanding the termination of this Agreement as set
forth in Section 7.01(a) above, until the sixth anniversary of the Closing Date
and thereafter for so long as Sprint's Percentage Interest is greater than the
Lower Threshold, then Sprint shall still be subject to the restrictions set
forth in Sections 4.01 and 5.01 hereof (the "Standstill Provisions") and, for so
long as Sprint's Percentage Interest remains greater than the Lower Threshold,
Sprint shall still have rights pursuant to this Agreement under Section 2.01
(subject to termination of such rights by virtue of Section 2.01(d)) and Section
3.01(b). In such event, the Standstill Provisions, Section 2.01, Section
3.01(b), Article VII and any definition or definitional provision of any of the
foregoing provisions of this Agreement shall remain in full force and effect
until such time as Sprint's Percentage Interest is less than the Lower Threshold

not give rise to any of the substantive rights or obligations that relate to
such definitions); provided, however, that during any period in which the
Standstill Provisions survive, Sprint and its Affiliates may directly approach
the Board of Directors of Newco in order to make an offer to effect a Business
Combination.

The parties hereto ("Parties") shall promptly notify each other of any change in

Notice shall be deemed to have been given as of the date when so personally
delivered, when actually delivered by the U.S. Postal Service at the proper
address, the next day when delivered during business hours to an overnight
delivery service properly addressed or when receipt of a telex or telecopy is

Agreement, the terms or conditions of this Agreement may not be waived unless
set forth in a writing signed by the Party entitled to the benefits thereof. No
waiver of any of the provisions of this Agreement shall be deemed or shall
constitute a waiver of such provision at any time in the future or a waiver of
any other provision hereof. The rights and remedies of the Parties are
cumulative and not alternative. Except as otherwise permitted in this Agreement,
neither the failure nor any delay by any Party in exercising any right, power or
privilege under this Agreement, any of the Ancillary Agreements or the documents
referred to in this Agreement or therein will operate as a waiver of such right,
power or privilege, and no single or partial exercise of any such right, power

or (ii) pursuant to any merger or sale of substantially all of the assets of
Sprint or such Affiliates (or any transaction having such effect) that is
pursuant to an agreement entered into after the Closing; provided, however,
that, in either such case, before such assignment may take effect, the proposed
successor or assignee agrees in writing to be bound by all of the provisions
hereof and executes an Irrevocable Proxy. Subject to the preceding sentence,
this Agreement will be binding upon, inure to the benefit of, and be enforceable
by, the parties and their respective successors and assigns. Any attempted
assignment in violation of this Section 7.05 shall be void.

                  SECTION 7.06. Governing Law. This Agreement shall be construed
in accordance with and governed by the laws of the State of Delaware, without
regard to conflict of laws principles.

                  SECTION 7.07. Severability. If any term or provision of this
Agreement or the application thereof to either party or set of circumstances
shall, in any jurisdiction and to any extent, be finally held invalid or
unenforceable, such term or provision shall only be ineffective as to such
jurisdiction, and only to the extent of such invalidity or unenforceability,
without invalidating or rendering unenforceable any other terms or provisions of
this Agreement or under any other circumstances, and the Parties shall negotiate
in good faith a substitute provision which comes as close as possible to the
invalidated or unenforceable term or provision, and which puts each party in a
position as nearly comparable as possible to the position it would have been in
but for the finding of invalidity or unenforceability, while remaining valid and
enforceable.

                  SECTION 7.08. Counterparts. This Agreement may be executed in
one or more counterparts each of which when so executed and delivered shall for
all purposes be deemed to be an original but all of which, when taken together,
shall constitute one and the same Agreement.

                  (c) No provision of this Agreement shall be interpreted in
favor of, or against, either of the Parties by reason of the extent to which

accordingly agreed that in the event of a failure by a party to perform its
obligations under this Agreement, the non-breaching Party shall be entitled to
specific performance through injunctive relief to prevent breaches of the
provisions of this Agreement and to enforce specifically the provisions of this
Agreement in any action instituted in any court having subject matter

         The undersigned hereby irrevocably appoint(s) EarthLink Network, Inc.,

                         CHAPTER 13. DISSENTERS' RIGHTS
 
sec. 1300. SHORT-FORM MERGER; PURCHASE OF SHARES AT FAIR MARKET VALUE;
"DISSENTING SHARES" AND DISSENTING SHAREHOLDER
 
(a) If the approval of the outstanding shares (Section 152) of a corporation is
    required for a reorganization under subdivisions (a) and (b) or subdivision
    (e) or (f) of Section 1201, each shareholder of the corporation entitled to
    vote on the transaction and each shareholder of a subsidiary corporation in
    a short-form merger may, by complying with this chapter, require the
    corporation in which the shareholder holds shares to purchase for cash at
    their fair market value the shares owned by the shareholder which are
    dissenting shares as defined in subdivision (b). The fair market value shall
    be determined as of the day before the first announcement of the terms of
    the proposed reorganization or short-form merger, excluding any appreciation
    or depreciation in consequence of the proposed action, but adjusted for any
    stock split, reverse stock split, or share dividend which becomes effective
    thereafter.
 
(b) As used in this chapter, "dissenting shares" means shares which come within
    all of the following descriptions:
 
    (1) Which were not immediately prior to the reorganization or short-form
       merger either (A) listed on any national securities exchange certified by
       the Commissioner of Corporations under subdivision (o) of Section 25100
       or (B) listed on the list of OTC margin stocks issued by the Board of
       Governors of the Federal Reserve System, and the notice of meeting of
       shareholders to act upon the reorganization summarizes this section and
       Sections 1301, 1302, 1303 and 1304; provided, however, that this
       provision does not apply to any shares with respect to which there exists
       any restriction on transfer imposed by the corporation or by any law or
       regulation; and provided, further, that this provision does not apply to
       any class of shares described in subparagraph (A) or (B) if demands for
       payment are filed with respect to 5 percent or more of the outstanding
       shares of that class.
 
    (2) Which were outstanding on the date for the determination of shareholders
       entitled to vote on the reorganization and (A) were not voted in favor of
       the reorganization or, (B) if described in subparagraph (A) or (B) of
       paragraph (1) (without regard to the provisos in that paragraph), were
       voted against the reorganization, or which were held of record on the
       effective date of a short-form merger; provided, however, that
       subparagraph (A) rather than subparagraph (B) of this paragraph applies
       in any case where the approval required by Section 1201 is sought by
       written consent rather than at a meeting.
 
    (3) Which the dissenting shareholder has demanded that the corporation
       purchase at their fair market value, in accordance with Section 1301.
 
    (4) Which the dissenting shareholder has submitted for endorsement, in
       accordance with Section 1302.
 
(c) As used in this chapter, "dissenting shareholder" means the recordholder of
dissenting shares and includes a transferee of record.
<PAGE>
sec. 1301 DISSENTER'S RIGHTS; DEMAND ON CORPORATION FOR PURCHASE OF SHARES
 
(a) If, in the case of a reorganization, any shareholders of a corporation have
    a right under Section 1300, subject to compliance with paragraphs (3) and
    (4) of subdivision (b) thereof, to require the corporation to purchase their
    shares for cash, such corporation shall mail to each such shareholder a
    notice of the approval of the reorganization by its outstanding shares
    (Section 152) within 10 days after the date of such approval, accompanied by
    a copy of Sections 1300, 1302, 1303, 1304 and this section, a statement of
    the price determined by the corporation to represent the fair market value
    of the dissenting shares, and a brief description of the procedure to be
    followed if the shareholder desires to exercise the shareholder's right
    under such sections. The statement of price constitutes an offer by the
    corporation to purchase at the price stated any dissenting shares as defined
    in subdivision (b) of Section 1300, unless they lose their status as
    dissenting shares under Section 1309.
 
(b) Any shareholder who has a right to require the corporation to purchase the
    shareholder's shares for cash under Section 1300, subject to compliance with
    paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
    corporation to purchase such shares shall make written demand upon the
    corporation for the purchase of such shares and payment to the shareholder
    in cash of their fair market value. The demand is not effective for any
    purpose unless it is received by the corporation or any transfer agent
    thereof (1) in the case of shares described in clause (i) or (ii) of
    paragraph (1) of subdivision (b) of Section 1300 (without regard to the
    provisos in that paragraph), not later than the date of the shareholders'
    meeting to vote upon the reorganization, or (2) in any other case within 30
    days after the date on which the notice of the approval by the outstanding
    shares pursuant to subdivision (a) or the notice pursuant to subdivision (i)
    of Section 1110 was mailed to the shareholder.
 
(c) The demand shall state the number and class of the shares held of record by
    the shareholder which the shareholder demands that the corporation purchase
    and shall contain a statement of what such shareholder claims to be the fair
    market value of those shares as of the day before the announcement of the
    proposed reorganization or short-form merger. The statement of fair market
    value constitutes an offer by the shareholder to sell the shares at such
    price.
 
sec. 1302. DISSENTING SHARES, STAMPING OR ENDORSING
 
    Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.
 
sec. 1303. DISSENTING SHAREHOLDER ENTITLED TO AGREED PRICE WITH INTEREST; TIME
OF PAYMENT
 
(a) If the corporation and the shareholder agree that the shares are dissenting
    shares and agree upon the price of the shares, the dissenting shareholder is
    entitled to the agreed price with interest thereon at the legal rate on
    judgments from the date of the agreement. Any agreements fixing the fair
    market value of any dissenting shares as between the corporation and the
    holders thereof shall be filed with the secretary of the corporation.
 
(b) Subject to the provisions of Section 1306, payment of the fair market value
    of dissenting shares shall be made within 30 days after the amount thereof
    has been agreed or within 30 days after any statutory or contractual

    the case of certificated securities, subject to surrender of the
    certificates therefor, unless provided otherwise by agreement.

sec. 1304. DISSENTERS ACTIONS; JOINDER; CONSOLIDATION; APPOINTMENT OF APPRAISERS
 
(a) If the corporation denies that the shares are dissenting shares, or the
    corporation and the shareholder fail to agree upon the fair market value of
    the shares, then the shareholder demanding purchase of such shares as
    dissenting shares or any interested corporation, within six months after the
    date on which notice of the approval by the outstanding shares (Section 152)
    or notice pursuant to subdivision (i) of Section 1110 was mailed to the
    shareholder, but not thereafter, may file a complaint in the superior court
    of the proper county praying the court to determine whether the shares are
    dissenting shares or the fair market value of the dissenting shares or both
    or may intervene in any action pending on such a complaint.
 
(b) Two or more dissenting shareholders may join as plaintiffs or be joined as
    defendants in any such action and two or more such actions may be
    consolidated.
 
(c) On the trial of the action, the court shall determine the issues. If the
    status of the shares as dissenting shares is in issue, the court shall first
    determine that issue. If the fair market value of the dissenting shares is
    in issue, the court shall determine, or shall appoint one or more impartial
    appraisers to determine, the fair market value of the shares.
 
sec. 1305. APPRAISERS DUTY AND REPORT; COURT JUDGMENT; PAYMENT; APPEAL; COSTS OF
ACTION
 
(a) If the court appoints an appraiser or appraisers, they shall proceed
    forthwith to determine the fair market value per share. Within the time
    fixed by the court, the appraisers, or a majority of them, shall make and
    file a report in the office of the clerk of the court. Thereupon, on the
    motion of any party, the report shall be submitted to the court and
    considered on such evidence as the court considers relevant. If the court
    finds the report reasonable, the court may confirm it.
 
(b) If a majority of the appraisers appointed fail to make and file a report
    within 10 days from the date of their appointment or within such further
    time as may be allowed by the court or the report is not confirmed by the
    court, the court shall determine the fair market value of the dissenting
    shares.
 
(c) Subject to the provisions of Section 1306, judgment shall be rendered
    against the corporation for payment of an amount equal to the fair market
    value of each dissenting share multiplied by the number of dissenting shares
    which any dissenting shareholder who is a party, or who has intervened, is
    entitled to require the corporation to purchase, with interest thereon at
    the legal rate from the date on which judgment was entered.
 
(d) Any such judgment shall be payable forthwith with respect to uncertificated
    securities and, with respect to certificated securities, only upon the
    endorsement and delivery to the corporation of the certificates for the
    shares described in the judgment. Any party may appeal from the judgment.
 
(e) The costs of the action, including reasonable compensation to the appraisers
    to be fixed by the court, shall be assessed or apportioned as the court
    considers equitable, but, if the appraisal exceeds the price offered by the
    corporation, the corporation shall pay the costs (including in the
    discretion of the court attorneys' fees, fees of expert witnesses and
    interest at the legal rate on judgments from the date of compliance with
    Sections 1300,1301 and 1302 if the value awarded by the court for the shares
    is more than 125 percent of the price offered by the corporation under
    subdivision (a) of Section 1301).
 
sec. 1306. DISSENTING SHAREHOLDERS; EFFECT OF PREVENTION OF PAYMENT OF FAIR
MARKET VALUE
 
    To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.
<PAGE>
sec. 1307. DISSENTING SHARES; DISPOSITION OF DIVIDENDS
 
    Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor.
 
sec. 1308. DISSENTING SHARES; RIGHTS AND PRIVILEGES
 
    Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined. A dissenting
shareholder may not withdraw a demand for payment unless the corporation
consents thereto.
 
sec. 1309. DISSENTING SHARES; LOSS OF STATUS
 
    Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:
 
    (a) The corporation abandons the reorganization. Upon abandonment of the
       reorganization, the corporation shall pay on demand to any dissenting
       shareholder who has initiated proceedings in good faith under this
       chapter all necessary expenses incurred in such proceedings and
       reasonable attorneys' fees.
 
    (b) The shares are transferred prior to their submission for endorsement in
       accordance with Section 1302 or are surrendered for conversion into
       shares of another class in accordance with the articles.
 
    (c) The dissenting shareholder and the corporation do not agree upon the
       status of the shares as dissenting shares or upon the purchase price of
       the shares, and neither files a complaint or intervenes in a pending
       action as provided in Section 1304, within six months after the date on
       which notice of the approval by the outstanding shares or notice pursuant
       to subdivision (i) of Section 1110 was mailed to the shareholder.
 
    (d) The dissenting shareholder, with the consent of the corporation,
       withdraws the shareholder's demand for purchase of the dissenting shares.
 
sec. 1310. SUSPENSION OF CERTAIN PROCEEDINGS WHILE LITIGATION IS PENDING
 
    If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation.
 
sec. 1311. CHAPTER INAPPLICABLE TO CERTAIN CLASSES OF SHARES
 
    This chapter, except Section 1312, does not apply to classes of shares whose
terms and provisions specifically set forth the amount to be paid in respect to
such shares in the event of a reorganization or merger.
 
sec. 1312. VALIDITY OF REORGANIZATION OR SHORT-FORM MERGER; ATTACK ON;
SHAREHOLDERS' RIGHTS; BURDEN OF PROOF
 
(a) No shareholder of a corporation who has a right under this chapter to demand
    payment of cash for the shares held by the shareholder shall have any right
    at law or in equity to attack the validity of the reorganization or
    short-form merger, or to have the reorganization or short-form merger set
    aside or rescinded, except in an action to test whether the number of shares
    required to authorize or approve the reorganization have been legally voted
    in favor thereof; but any holder of shares of a class whose terms and
    provisions specifically set forth the amount to be paid in respect to them
    in the event of a reorganization or short-form merger is entitled to payment
    in accordance with those terms and provisions or, if the principal terms of
    the reorganization are approved pursuant to subdivision (b) of Section 1202,
    is entitled to payment in accordance with the terms and provisions of the
    approved reorganization.
<PAGE>
(b) If one of the parties to a reorganization or short-form merger is directly
    or indirectly controlled by, or under common control with, another party to
    the reorganization or short-form merger, subdivision (a) shall not apply to
    any shareholder of such party who has not demanded payment of cash for such
    shareholder's shares pursuant to this chapter; but if the shareholder
    institutes any action to attack the validity of the reorganization or
    short-form merger or to have the reorganization or short-form merger set
    aside or rescinded, the shareholder shall not thereafter have any right to
    demand payment of cash for the shareholder's shares pursuant to this
    chapter. The court in any action attacking the validity of the
    reorganization or short-form merger or to have the reorganization or
    short-form merger set aside or rescinded shall not restrain or enjoin the
    consummation of the transaction except upon 10 days' prior notice to the
    corporation and upon a determination by the court that clearly no other
    remedy will adequately protect the complaining shareholder or the class of
    shareholders of which such shareholder is a member.
 
(c) If one of the parties to a reorganization or short-form merger is directly
    or indirectly controlled by, or under common control with, another party to
    the reorganization or short-form merger, in any action to attack the
    validity of the reorganization or short-form merger or to have the
    reorganization or short-form merger set aside or rescinded, (1) a party to a
    reorganization or short-form merger which controls another party to the
    reorganization or short-form merger shall have the burden of proving that
    the transaction is just and reasonable as to the shareholders of the
    controlled party, and (2) a person who controls two or more parties to a
    reorganization shall have the burden of proving that the transaction is just
    and reasonable as to the shareholders of any party so controlled.
