Item 5.  Other Events.

             On October 5, 1999, MCI WORLDCOM, Inc. ("MCI WorldCom") announced
that it had entered into an Agreement and Plan of Merger dated as of
October 4, 1999 (the "Merger Agreement"), between MCI WorldCom and Sprint
Corporation ("Sprint"). Under the terms of the Merger Agreement, Sprint
shall be merged with and into MCI WorldCom (the "Merger").

          Under the Merger Agreement, each share of Sprint's FON common
stock will be exchanged for $76.00 of MCI WorldCom common stock, subject to
a collar. In addition, each share of Sprint's PCS common stock will be
exchanged for one share of a new WorldCom PCS tracking stock and 0.1547
shares of MCI WorldCom common stock. The terms of the WorldCom PCS tracking
stock will be equivalent to those of Sprint's PCS common stock and will
track the performance of the PCS business of the surviving company in the
Merger. The Merger will be accounted for as a purchase and will be tax-free
to Sprint stockholders.

          The actual number of shares of MCI WorldCom common stock to be
exchanged for each share of Sprint's FON common stock will be determined
based on the average trading prices prior to the closing, but will not be
less than 0.9400 shares (if MCI WorldCom's average stock price exceeds
$80.85) or more than 1.2228 shares (if MCI WorldCom's average stock price
is less than $62.15).

          The Merger is subject to various conditions set forth in the Merger
Agreement, including the adoption of the Merger Agreement by stockholders of
Sprint, the approval of the Merger by shareholders of MCI WorldCom, the
approval of the issuance of MCI WorldCom common stock in the Merger by
shareholders of MCI WorldCom, certain U.S. and foreign regulatory approvals
and other customary conditions. It is anticipated that the Merger will close
in the second half of 2000.

          Attached and incorporated herein by reference in their entirety
as Exhibits 2.1 and 99.1 are copies of (1) the Merger Agreement and (2) the
press release dated October 5, 1999.

and unless provided for by applicable law, holders of shares of MCI WorldCom
Series B

                                  ARTICLE II

                           EXCHANGE OF CERTIFICATES

          2.1 Exchange Agent. Prior to the Effective Time, MCI WorldCom shall
appoint The Bank of New York or another commercial bank or trust company
reasonably satisfactory to Sprint to act as exchange agent hereunder for the
purpose of exchanging Certificates for the applicable Merger Consideration
(the "Exchange Agent"). At or prior to the Effective Time, MCI WorldCom shall
deposit with the Exchange Agent, in trust for the benefit of holders of shares
of Sprint Capital Stock, certificates representing the applicable MCI WorldCom
Capital Stock issuable pursuant to Section 1.8 in exchange for outstanding
shares of Sprint Capital Stock in the Merger pursuant to Section 1.8. MCI
WorldCom agrees to make available to the Exchange Agent from time to time as
needed, cash sufficient to pay cash in lieu of fractional shares pursuant to
Section 2.5 and any dividends and other distributions pursuant to Section 2.3.

          2.2 Exchange Procedures. As soon as reasonably practicable after the

mail to each holder of a Certificate (i) a letter of transmittal which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the
Exchange Agent, and which letter shall be in such form and have such other
provisions as MCI WorldCom may reasonably specify and (ii) instructions for
effecting the surrender of such Certificates in exchange for the applicable
Merger Consideration. Upon surrender of a Certificate to the Exchange Agent
together with such letter of transmittal, duly executed and completed in
accordance with the instructions thereto, and such other documents as may
reasonably be required by the Exchange Agent, the holder of such Certificate,
if it is a Certificate for Sprint Capital Stock shall be entitled to receive
in exchange therefor (A) one or more shares of applicable MCI WorldCom Capital
Stock representing, in the aggregate, the whole number of shares that such
holder has the right to receive pursuant to Section 1.8, and (B) a check in
the amount equal to the cash that such holder has the right to receive
pursuant to the provisions of this Article II including cash in lieu of any
fractional shares

                                                                             8

of applicable MCI WorldCom Capital Stock pursuant to Section 2.5 and any
dividends or other distributions pursuant to Section 2.3, and in each case the
Certificate so surrendered shall forthwith be canceled. No interest will be
paid or will accrue on any cash payable pursuant to Section 2.3 or Section
2.5. In the event of a transfer of ownership of Sprint Capital Stock which is
not registered in the transfer records of Sprint, one or more shares of
applicable MCI WorldCom Capital Stock evidencing, in the aggregate, the proper
number of shares of applicable MCI WorldCom Capital Stock and a check in the
proper amount of cash in lieu of any fractional shares of applicable MCI
WorldCom Capital Stock pursuant to Section 2.5 and any dividends or other
distributions to which such holder is entitled pursuant to Section 2.3, may be
issued with respect to such Sprint Capital Stock to such a transferee if the
Certificate representing such shares of Sprint Capital Stock is presented to
the Exchange Agent, accompanied by all documents required to evidence and
effect such transfer and to evidence that any applicable stock transfer taxes
have been paid.

          2.3 Distributions with Respect to Unexchanged Shares. No dividends
or other distributions declared or made with respect to shares of MCI WorldCom
Capital Stock with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the shares of MCI
WorldCom Capital Stock that such holder would be entitled to receive upon
surrender of such Certificate and no cash payment in lieu of fractional shares
of MCI WorldCom Capital Stock shall be paid to any such holder pursuant to
Section 2.5 until such holder shall surrender such Certificate in accordance
with Section 2.2. Subject to the effect of applicable laws, following
surrender of any such Certificate, there shall be paid to such holder of
shares of MCI WorldCom Capital Stock issuable in exchange therefor, without
interest, (a) promptly after the time of such surrender, the amount of any
cash payable in lieu of fractional shares of MCI WorldCom Capital Stock to
which such holder is entitled pursuant to Section 2.5 and the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of MCI WorldCom Capital
Stock and (b) at the appropriate payment date, the amount of dividends or
other distributions with a record date after the Effective Time but prior to
such surrender and a payment date subsequent to such surrender payable with
respect to such shares of MCI WorldCom Capital Stock.

          2.4 No Further Ownership Rights in Sprint Capital Stock. All shares
of MCI WorldCom Capital Stock issued and cash paid upon conversion of shares
of Sprint Capital Stock in accordance with the terms of Article I and this
Article II (including any cash paid pursuant to Section 2.3 or 2.5) shall be
deemed to have been issued or paid in full satisfaction of all rights
pertaining to the shares of Sprint Capital Stock, subject, however, to the
Surviving Corporation's obligation to pay any dividends or make any other
distributions with a record date prior to the Effective Time which may have
been declared or made by Sprint on such shares of Sprint Capital Stock which
remain unpaid at the Effective Time, and there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Sprint Capital Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation or the Exchange Agent
for any reason, they shall be canceled and exchanged as provided in this
Article II.

          2.5 No Fractional Shares of MCI WorldCom Capital Stock. (a) No
certificates or scrip or shares of MCI WorldCom Capital Stock representing
fractional shares of MCI WorldCom Capital Stock shall be issued upon the
surrender for exchange

                                                                             9

of Certificates and such fractional share interests will not entitle the owner
thereof to vote or to have any rights of a shareholder of MCI WorldCom or a
holder of shares of MCI WorldCom Capital Stock.

          (b) Notwithstanding any other provision of this Agreement, each
holder of shares of Sprint Common Stock exchanged pursuant to the Merger who
would otherwise have been entitled to receive a fraction of a share of
applicable MCI WorldCom Capital Stock (after taking into account all
Certificates delivered by such holder) shall receive, in lieu thereof, cash
(without interest) in an amount equal to the product of (i) such fractional
part of a share of applicable MCI WorldCom Capital Stock multiplied by (ii)
the per share closing price of applicable MCI WorldCom Common Stock quoted on
Nasdaq on the Closing Date. The fractional share interests of MCI WorldCom
Capital Stock will be aggregated, and no recordholder of Sprint Capital Stock
will receive cash in an amount equal to or greater than the value of one full
share of MCI WorldCom Capital Stock determined as of the Effective Time.

          2.6 No Liability. None of Sprint, MCI WorldCom, the Surviving
Corporation or the Exchange Agent shall be liable to any Person in respect of
any Merger Consideration, any dividends or distributions with respect thereto
or any cash in lieu of fractional shares of applicable MCI WorldCom Capital
Stock, in each case delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law. If any Certificate shall not have
been surrendered prior to three years after the Effective Time (or immediately
prior to such earlier date on which any Merger Consideration, any dividends or
distributions payable to the holder of such Certificate or any cash payable in
lieu of fractional shares of MCI WorldCom Capital Stock pursuant to this
Article II, would otherwise escheat to or become the property of any
Governmental Entity), any such Merger Consideration, dividends or
distributions in respect thereof or such cash shall, to the extent permitted
by applicable law, be delivered to MCI WorldCom, upon demand, and any holders
of Sprint Capital Stock who have not theretofore complied with the provisions
of this Article II shall thereafter look only to MCI WorldCom for satisfaction
of their claims for such Merger Consideration, dividends or distributions in
respect thereof or such cash.

          2.7 Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the
Person claiming such Certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such Person of a bond in
such reasonable amount as the Surviving Corporation may direct as indemnity
against any claim that may be made against it with respect to such
Certificate, the Exchange Agent will deliver in exchange for such lost, stolen
or destroyed Certificate the applicable Merger Consideration with respect to
the shares of Sprint Capital Stock formerly represented thereby, any cash in
lieu of fractional shares of MCI WorldCom Capital Stock, and unpaid dividends
and distributions on shares of MCI WorldCom Capital Stock deliverable in
respect thereof, pursuant to this Agreement.

          2.8 Withholding Rights. The Surviving Corporation shall be entitled
to deduct and withhold from the consideration otherwise payable pursuant to
this Agreement to any holder of shares of Sprint Capital Stock such amounts as
it is required to deduct and withhold with respect to the making of such
payment under the Code and the rules and regulations promulgated thereunder,
or any provision of state, local or foreign tax law. To the extent that
amounts are so withheld by the Surviving Corporation

                                                                            10

such withheld amounts shall be treated for all purposes of this Agreement as
having been paid to the holder of the shares of Sprint Capital Stock in
respect of which such deduction and withholding was made by the Surviving
Corporation.

          2.9 Stock Transfer Books. At the close of business, New York City
time, on the day the Effective Time occurs, the stock transfer books of Sprint
shall be closed and there shall be no further registration of transfers of
shares of Sprint Capital Stock thereafter on the records of Sprint. From and
after the Effective Time, the holders of Certificates shall cease to have any
rights with respect to such shares of Sprint Capital Stock formerly
represented thereby, except as otherwise provided herein or by law. On or
after the Effective Time, any Certificates presented to the Exchange Agent or
MCI WorldCom for any reason shall be converted into the Merger Consideration
with respect to the shares of Sprint Capital Stock formerly represented
thereby, any cash in lieu of fractional shares of MCI WorldCom Capital Stock
to which the holders thereof are entitled pursuant to Section 2.5 and any
dividends or other distributions to which the holders thereof are entitled
pursuant to Section 2.3.

contemplated by Section 5.6, as of the date of this Agreement, there are no
securities, options, warrants, calls, rights, commitments, agreements,
arrangements or undertakings of any kind to which Sprint or any of its
Subsidiaries is a party or by which any of them is bound obligating Sprint or
any of its Subsidiaries to issue, deliver or sell, or cause to be issued,
delivered or sold, additional shares of capital stock or other voting

          (c) Authority; No Conflicts. (i) Sprint has all requisite corporate

Agreement by the Required Sprint Vote. This Agreement has been duly executed
and delivered by Sprint and constitutes a valid and binding agreement of
Sprint, enforceable against it in accordance with its terms.

          (ii) The execution and delivery of this Agreement do not or will
not, as the case may be, and the consummation of the Merger and the other
transactions contemplated hereby will not, subject to the adoption of this
Agreement by the Required Sprint Vote, conflict with, or result in any
violation of, or constitute a default (with or without notice or lapse of
time, or both) under, or give rise to a right of termination, amendment,
cancelation or acceleration of any obligation or the loss of a material
benefit under, or the creation of a lien, pledge, security interest, charge or
other encumbrance on any assets (any such conflict, violation, default, right
of termination, amendment, cancelation or acceleration, loss or creation, a
"Violation") pursuant to: (A) any provision of the articles of incorporation
or by-laws of Sprint or the governing documents of any Subsidiary of Sprint,

aggregate, to have a Material Adverse Effect on Sprint and subject to

plan or other agreement, obligation, instrument, permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to Sprint or any Subsidiary of Sprint or their
respective properties or assets.

          (iii) No consent, approval, order or authorization of, or
registration, declaration or filing with, any supranational, national, state,
municipal or local government, any instrumentality, subdivision, court,
administrative agency or commission or other authority thereof, or any
quasi-governmental or private body exercising any regulatory, taxing,
importing or other governmental or quasi-governmental authority, including the
European Union (a "Governmental Entity"), is required by or with respect to
Sprint or any Subsidiary of Sprint in connection with the execution and
delivery of this Agreement by Sprint or the consummation of the Merger and the
other transactions contemplated hereby, except for those required under or in
relation to (A) the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and the rules and regulations promulgated thereunder (the "HSR Act"),
and Council Regulation (EEC) No. 4064/89 ("Regulation 4064/89"), (B) the
Communications Act of 1934, as amended, and the rules and regulations
promulgated thereunder (the "Communications Act"), and any other rules,
regulations, practices and policies promulgated by the Federal Communications

Laws"), (D) the Securities Act of 1933, as amended, and the rules and
regulations promulgated thereunder (the "Securities Act"), (E) the Securities

bodies, (H) rules and regulations of the New York Stock Exchange, Inc.
("NYSE"), (I) antitrust or other competition laws of other jurisdictions, and
(J) such consents, approvals, orders, authorizations, registrations,
declarations and filings the failure of which to make or obtain is not
reasonably likely, individually or in the aggregate, to have a Material
Adverse Effect on Sprint. Consents, approvals, orders, authorizations,
registrations, declarations and filings required under or in relation to any
of the foregoing clauses (A) through (G) and clause (I) are hereinafter
referred to as "Required Consents".

          (d) Reports and Financial Statements. Sprint has filed all reports,
schedules, forms, statements and other documents required to be filed by it
with the Securities and Exchange Commission (the "SEC") since January 1, 1998
(collectively, including all exhibits thereto, the "Sprint SEC Reports"). No
Significant Subsidiary of Sprint is required to file any form, report or other
document with the SEC. None of the Sprint SEC Reports when filed contained any
untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. Each of
the financial statements (including the related notes) included in the Sprint
SEC Reports presents fairly, in all material respects, the consolidated
financial position and consolidated results of operations and cash flows of
Sprint and its Subsidiaries as of the respective dates or for the respective
periods set forth therein, all in



<PAGE>


                                                                            14

conformity with United States generally accepted accounting principles ("U.S.
GAAP") consistently applied during the periods involved except as otherwise
noted therein, and subject, in the case of the unaudited interim financial
statements, to normal and recurring year-end adjustments. All of such Sprint
SEC Reports, as of their respective dates (and as of the date of any amendment
to the respective Sprint SEC Report), complied as to form in all material
respects with the applicable requirements of the Securities Act and the
Exchange Act.

          (e) Information Supplied. (i) None of the information supplied or to
be supplied by Sprint for inclusion or incorporation by reference in (A) the
Form S-4 to be filed with the SEC by MCI WorldCom in connection with the
issuance of the MCI WorldCom Capital Stock in the Merger will, at the time the
Form S-4 becomes effective under the Securities Act, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading and
(B) the Joint Proxy Statement/Prospectus included in the Form S-4 related to
the Sprint Stockholders Meeting and the MCI WorldCom Shareholders Meeting and
the MCI WorldCom Capital Stock to be issued in the Merger will, on the date it
is first mailed to Sprint stockholders or MCI WorldCom shareholders or at the
time of the Sprint Stockholders Meeting or the MCI WorldCom Shareholders
Meeting, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading. The Joint Proxy Statement/Prospectus will comply as to form in
all material respects with the requirements of the Exchange Act.

          (ii) Notwithstanding the foregoing provisions of this Section
3.1(e), no representation or warranty is made by Sprint with respect to
statements made or incorporated by reference in the Form S-4 or the Joint
Proxy Statement/Prospectus based on information supplied by MCI WorldCom for
inclusion or incorporation by reference therein.

          (f) Litigation. There is no suit, action, proceeding, claim or
investigation pending or, to the Knowledge of Sprint, threatened against or
affecting Sprint or any of its Subsidiaries that is reasonably likely,
individually or in the aggregate, to have a Material Adverse Effect on Sprint
nor is there any judgment, decree, injunction, rule or order of any
Governmental Entity or arbitrator outstanding against Sprint or any of its
Subsidiaries having, or that is reasonably likely, individually or in the
aggregate, to have a Material Adverse Effect on Sprint.

          (g) Compliance with Applicable Laws. Sprint and its Subsidiaries
hold all permits, licenses, variances, exemptions, orders, registrations and
approvals of all Governmental Entities which are required for the operation of
the business of Sprint and its Subsidiaries taken as a whole (the "Sprint
Permits"), except where the failure to have any such Sprint Permits is not
reasonably likely, individually or in the aggregate, to have a Material
Adverse Effect on Sprint. Sprint and its Subsidiaries are in compliance with
the terms of the Sprint Permits and all applicable statutes, laws, ordinances,
rules and regulations, except where the failure so to comply is not reasonably
likely, individually or in the aggregate, to have a Material Adverse Effect on
Sprint. Subject to obtaining the Required Consents, the Merger, in and of
itself, would not cause the revocation or cancelation of any Sprint Permit
that is reasonably likely, individually or in the aggregate, to have a
Material Adverse Effect on Sprint.

                                                                            15

          (h) State Takeover Statutes; Approvals. Each of the Board of
Directors of Sprint (including the disinterested directors thereof) and the
Capital Stock Committee of such Board of Directors has approved and
recommended the terms of this Agreement and the consummation of the Merger and
the other transactions contemplated by this Agreement and such approval of the
Board of Directors of Sprint constitutes approval of the Merger and the other
transactions contemplated by this Agreement by the Board of Directors of
Sprint to the extent applicable under the provisions of Section 17-1286 et
seq. and Section 17-12,100 et seq. of the KGCC and Article Seventh of Sprint's
articles of incorporation and represents all the action necessary to ensure
that Section 17-1286 et seq. and Section 17-12,100 et seq. of the KGCC and
Article Seventh of Sprint's articles of incorporation do not apply to MCI
WorldCom in connection with the Merger and the other transactions contemplated
by this Agreement. No other Kansas or Georgia state takeover statute is
applicable to Sprint in connection with this Agreement, the Merger or the
other transactions contemplated hereby. Other than those that have been made
prior to the date hereof, no approval or determination of the Board of
Directors of Sprint or any committee thereof is required with respect to any
class or series of Sprint Capital Stock or under Sprint's articles of
incorporation, by-laws or governance policies to approve this Agreement or any
of the transactions contemplated hereby.

          (i) Intellectual Property; Year 2000. (i) Sprint and its
Subsidiaries own, or are validly licensed or otherwise have the right to use,
all patents, patent rights, trademarks, trade secrets, trade names, service
marks, copyrights and other proprietary intellectual property rights and
computer programs (the "Intellectual Property Rights") used in the business of
Sprint and its Subsidiaries, except for such Intellectual Property Rights the
failure of which to own, license or otherwise have the right to use is not
reasonably likely, individually or in the aggregate, to have a Material
Adverse Effect on Sprint.

          (ii) To the Knowledge of Sprint, neither Sprint nor any of its
Subsidiaries has interfered with, infringed upon, misappropriated or otherwise
come into conflict with any Intellectual Property Rights or other proprietary
information of any other Person, except for any such interference,
infringement, misappropriation or other conflict which is not reasonably
likely, individually or in the aggregate, to have a Material Adverse Effect on
Sprint. To the Knowledge of Sprint, neither Sprint nor any of its Subsidiaries
has received any written charge, complaint, claim, demand or notice alleging
any such interference, infringement, misappropriation or other conflict
(including any claim that Sprint or any such Subsidiary must license or
refrain from using any Intellectual Property Rights or other proprietary
information of any other Person) which has not been settled or otherwise fully
resolved, except with respect to any such interference, infringement,
misappropriation or other conflict which is not reasonably likely,
individually or in the aggregate, to have a Material Adverse Effect on Sprint.
To the Knowledge of Sprint, no other Person has interfered with, infringed
upon, misappropriated or otherwise come into conflict with any Intellectual
Property Rights of Sprint or any of its Subsidiaries, except for any such
interference, infringement, misappropriation or other conflict which is not
reasonably likely, individually or in the aggregate, to have a Material
Adverse Effect on Sprint.

          (iii) As of the date of this Agreement, Sprint and its Subsidiaries
have undertaken a concerted effort to ensure that all of the computer
software, computer firmware, computer hardware, and other similar or related
items of automated, computerized, and/or software system(s) that are to be
used or relied on by Sprint or any



<PAGE>


                                                                            16

of its Subsidiaries in the conduct of their respective businesses will not
malfunction, will not cease to function, will not generate incorrect data, and
will not provide incorrect results when processing, providing and/or receiving
(i) date-related data into and between the years 1999 and 2000 and (ii)
date-related data in connection with any valid date in the twentieth and
twenty-first centuries. As of the date of this Agreement, Sprint reasonably
believes that such effort will be successful.

          (j) Absence of Certain Changes or Events. Except for liabilities
incurred in connection with this Agreement or the transactions contemplated
hereby, since June 30, 1999, Sprint and its Subsidiaries have conducted their

copy of which opinion will promptly be made available to Sprint.

          (o) ERISA Compliance. (i) With respect to MCI WorldCom's Benefit

reports, and the reserve for current taxes shown on the most recent financial
statements contained in the MCI WorldCom Filed SEC Reports (in addition to any
reserve for deferred taxes established to reflect timing differences between
book and tax income) is adequate to cover all taxes payable by MCI WorldCom
and its Subsidiaries and each MCI WorldCom Consolidated Group for all taxable
periods and portions thereof through the date of such financial statements,
except for any such failure to file, incompleteness or inaccuracy, failure to
pay, or inadequacy of such reserve, that is not reasonably likely,
individually or in the aggregate, to have a Material Adverse Effect on MCI
WorldCom.

          (ii) No deficiencies for any taxes have been proposed, asserted or
assessed in writing against MCI WorldCom or any of its Subsidiaries or any MCI
WorldCom Consolidated Group that are not adequately reserved for, except for
deficiencies that are not reasonably likely, individually or in the aggregate,
to have a Material Adverse Effect on MCI WorldCom and no requests for waivers
of time to assess any such taxes have been granted or are pending (other than
with respect to years that are currently under examination by the Internal
Revenue Service or other applicable taxing authorities). The statute of
limitations on assessment or collection of any Federal taxes due from MCI
WorldCom and its Subsidiaries has expired for all taxable years of MCI
WorldCom and each of its Subsidiaries through 1987. The Federal income tax
returns of MCI WorldCom and each of its Subsidiaries have been examined by and
settled with the Internal Revenue Services for all years through 1987.

          (iii) Neither MCI WorldCom nor any of its Subsidiaries has taken or
has agreed to take any action or has any Knowledge of any fact, agreement,
plan or other circumstance that is reasonably likely to prevent the Merger
from qualifying as a "reorganization" within the meaning of Section 368(a) of
the Code.

          (iv) Neither MCI WorldCom nor any of its Subsidiaries has
constituted either a "distributing corporation" or a "controlled corporation"
(within the meaning of Section 355(a)(1)(A) of the Code) in a distribution of
stock qualifying for tax-free treatment under Section 355 of the Code (A) in
the two years prior to the date of this Agreement or (B) in a distribution
which could otherwise constitute part of a "plan" or series of "related
transactions" (within the meaning of Section 355(e) of the Code) in
conjunction with the Merger.

          (v) MCI WorldCom does not believe that it is a "United States real
property holding corporation" within the meaning of Section 897(c)(2) of the
Code during the applicable period specified in Section 897(c)(1)(A)(ii) of the
Code, although it has not determined or established whether it will be a
United States real property holding corporation in the future.

          (vi) As used in this Agreement, "MCI WorldCom Consolidated Group"
means any affiliated group within the meaning of Section 1504(a) of the Code,
in which MCI WorldCom (or any Subsidiary of MCI WorldCom) is or has ever been
a member or any group of corporations with which MCI WorldCom files, has filed
or is or was required to file an affiliated, consolidated, combined, unitary
or aggregate tax return.

Disclosure Schedule or to the extent that Sprint shall otherwise consent in

WorldCom pays (or establishes a record date for payment of) any dividend on,
or makes any other distribution in respect of, MCI WorldCom Common Stock, the
applicable Merger Consideration shall be appropriately adjusted to reflect
such dividend or distribution. Without limiting the foregoing, the issuance of

adjustment pursuant to this Section 4.2(b).

          (c) No Acquisitions. MCI WorldCom shall not, and shall not permit
any of its Subsidiaries to, acquire or agree to acquire by merging or
consolidating with, or by purchasing a substantial equity interest in or all

WorldCom Shareholders Meeting, will contain an untrue statement of a material
fact or omit to state a material fact required to be stated therein or

information supplied or to be supplied by Sprint for inclusion or
incorporation by reference in the Joint Proxy Statement/Prospectus and each
amendment or supplement thereto, at the time of mailing thereof and at the
time of the Sprint Stockholders Meeting or the MCI WorldCom Shareholders
Meeting, will contain an untrue statement of a material fact or omit to state

not misleading. For purposes of the foregoing, it is understood and agreed
that information concerning or related to MCI WorldCom and the MCI WorldCom
Shareholders Meeting will be deemed to have been supplied by MCI WorldCom and
information concerning or related to Sprint and the Sprint Stockholders
Meeting shall be deemed to have been supplied by Sprint. No amendment or
supplement to the information supplied by Sprint for inclusion in the Joint
Proxy Statement/Prospectus shall be made without the approval of Sprint, which
approval shall not be unreasonably withheld or delayed.

          (b) Sprint shall, as promptly as practicable following the execution
of this Agreement, duly call, give notice of, convene and hold a meeting of
its stockholders (the "Sprint Stockholders Meeting") for the purpose of
obtaining the Required Sprint Vote with respect to the transactions
contemplated by this Agreement, shall use its reasonable best efforts, subject
to Section 5.4, to solicit the adoption of this Agreement by the Required

Without limiting the generality of the foregoing but subject to its rights
pursuant to Sections 5.4 and 7.1(e), Sprint agrees that its obligations

the commencement, public proposal, public disclosure or communication to
Sprint of any Sprint Acquisition Proposal.

          (c) MCI WorldCom shall, as promptly as practicable following the

shall not be affected by the commencement, public proposal, public disclosure
or communication to MCI WorldCom of any MCI WorldCom Acquisition Proposal.

          (d) The Sprint Stockholders Meeting and the MCI WorldCom
Shareholders Meeting shall take place on the same date, to the extent
practicable; provided that, notwithstanding anything in this Agreement,
neither such meeting shall take place earlier than the 121st day following the
date of this Agreement.

          5.2 Access to Information. Upon reasonable notice, each of MCI
WorldCom and Sprint shall, and shall cause its Subsidiaries to, afford to the
other party and to the officers, employees, accountants, counsel, financial
advisors and other representatives of such other party reasonable access
during normal business hours, during the period prior to the Effective Time,
to all its properties, books, contracts, commitments and records and, during
such period, each of MCI WorldCom and Sprint shall, and shall cause its
Subsidiaries to, furnish promptly to the other party consistent with its legal
obligations, all other information concerning its business, properties and
personnel as such other party may reasonably request; provided, however, that
each of MCI WorldCom and Sprint may restrict the foregoing access to the
extent that (i) a Governmental Entity requires either party or any of its
Subsidiaries to restrict access to any properties or information reasonably
related to any such contract on the basis of applicable laws and regulations
with respect to national security matters or (ii) in the reasonable judgment
of such party, any law, treaty, rule or regulation of any Governmental Entity
applicable to such party requires it or its Subsidiaries to restrict access to
any properties or information. The parties will hold any such information in
confidence to the extent required by, and in accordance with, the provisions
of the letter dated September 22, 1999, between Sprint and MCI WorldCom (the
"Confidentiality Agreement"). Any investigation by MCI WorldCom or Sprint
shall not affect the representations and warranties of Sprint or MCI WorldCom,
as the case may be.

          5.3 Reasonable Best Efforts. (a) Subject to the terms and conditions
of this Agreement, each party hereto will use its reasonable best efforts to
(i) take, or cause to be taken, all actions and to do, or cause to be done,
all things necessary, proper or advisable under applicable laws and
regulations to consummate the Merger and the other transactions contemplated
by this Agreement as soon as practicable after the date hereof and (ii) obtain
and maintain all approvals, consents, waivers, registrations, permits,
authorizations, clearances and other confirmations required to be obtained
from any third party and/or any Governmental Entity that are reasonably
necessary to consummate the Merger and the transactions contemplated hereby
(each a "Required Approval"). In furtherance and not in limitation of the
foregoing, each party hereto agrees to make, as promptly as practicable, to
the extent it has not already done so, (i) an appropriate filing of a
Notification and Report Form pursuant to the HSR Act with respect to the
transactions contemplated hereby (which filing shall be made in any event
within five Business Days of the date hereof), (ii) appropriate filings with
the FCC and PUCs with respect to the transactions contemplated hereby, (iii)
appropriate filings with the European Commission in accordance with applicable
competition, merger control, antitrust or similar laws within the time periods
specified thereunder, and (iv) all necessary filings with other Governmental
Entities relating to the Merger, and, in each case, to supply as promptly as
practicable any additional information and documentary material that may be
requested pursuant to the such laws and to use reasonable best efforts to
cause the expiration or termination of the applicable waiting periods under
the HSR Act and the receipt of Required Approvals under such other laws as
soon as

                                                                            35

practicable. Notwithstanding the foregoing, nothing in this Section 5.3 shall
require, or be deemed to require, (i) MCI WorldCom or Sprint to agree to or
effect any divestiture or take any other action if doing so would,
individually or in the aggregate, reasonably be expected to materially impair
the parties' ability to achieve the overall benefits expected, as of the date
hereof, to be realized from the consummation of the Merger or (ii) MCI
WorldCom or Sprint to agree to or effect any divestiture or take any other
action that is not conditional on the consummation of the Merger.

          (b) Each of MCI WorldCom and Sprint shall, in connection with the
efforts referenced in Section 5.3(a) to obtain all Required Approvals, use its
reasonable best efforts to (i) cooperate in all respects with each other in
connection with any filing or submission and in connection with any
investigation or other inquiry, including any proceeding initiated by a
private party; (ii) promptly inform the other party of any communication
received by such party from, or given by such party to, the FCC, PUCs, the
Antitrust Division of the Department of Justice (the "DOJ") or any other
Governmental Entity and of any material communication received or given in
connection with any proceeding by a private party, in each case regarding any
of the transactions contemplated hereby, and (iii) permit the other party to
review any communications given by it to, and consult with each other in
advance to the extent practicable of any meeting or conference with, the FCC,
PUCs, the DOJ or any such other Governmental Entity or, in connection with any
proceeding by a private party, with any other Person, and to the extent
permitted by the FCC, PUCs, the DOJ or such other applicable Governmental
Entity or other Person, give the other party the opportunity to attend and
participate in such meetings and conferences.

          (c) In furtherance and not in limitation of the covenants of the
parties contained in Sections 5.3(a) and 5.3(b), if any administrative or
judicial action or proceeding, including any proceeding by a private party, is
instituted (or threatened to be instituted) challenging any transaction
contemplated by this Agreement as violative of any Regulatory Law, or if any
statute, rule, regulation, executive order, decree, injunction or
administrative order is enacted, entered, promulgated or enforced by a
Governmental Entity which would make the Merger or the transactions
contemplated hereby illegal or would otherwise prohibit or materially impair
or delay the consummation of the Merger or the transactions contemplated
hereby, each of MCI WorldCom and Sprint shall cooperate in all respects with
each other and use its respective reasonable best efforts to contest and
resist any such action or proceeding and to have vacated, lifted, reversed or
overturned any decree, judgment, injunction or other order, whether temporary,
preliminary or permanent, that is in effect and that prohibits, prevents or
restricts consummation of the Merger or the transactions contemplated by this
Agreement and to have such statute, rule, regulation, executive order, decree,
injunction or administrative order repealed, rescinded or made inapplicable.
Notwithstanding the foregoing or any other provision of this Agreement,
nothing in this Section 5.3 shall limit a party's right to terminate this
Agreement pursuant to Section 7.1(b) or 7.1(c) so long as such party has up to
then complied in all respects with its obligations under this Section 5.3. For
purposes of this Agreement, "Regulatory Law" means the Sherman Act, as
amended, the Clayton Act, as amended, the HSR Act, the Federal Trade
Commission Act, as amended, the Federal Communications Act, as amended,
Regulation 4064/89, and all other Federal, state and foreign, if any,
statutes, rules, regulations, orders, decrees, administrative and judicial
doctrines and other laws that are designed or intended to regulate mergers,
acquisitions or other business combinations.

          (d) Sprint and its Board of Directors shall, if any state takeover
statute or similar statute becomes applicable to this Agreement, the Merger or
any other transactions contemplated hereby or thereby, take all action
reasonably necessary to ensure that the Merger and the other transactions
contemplated by this Agreement may be consummated as promptly as practicable
on the terms contemplated hereby or thereby and otherwise to minimize the
effect of such statute or regulation on this Agreement, the Merger and the
other transactions contemplated hereby.

          (e) MCI WorldCom and its Board of Directors shall, if any state
takeover statute or similar statute becomes applicable to this Agreement, the
Merger or any other transactions contemplated hereby, to the extent legally
permissible take all action reasonably necessary to ensure that the Merger and
the other transactions contemplated by this Agreement may be consummated as
promptly as practicable on the terms contemplated hereby and otherwise to
minimize the effect of such statute or regulation on this Agreement, the
Merger and the other transactions contemplated hereby.

          5.4 No Solicitation by Sprint. (a) Sprint shall not, nor shall it
permit any of its Subsidiaries to, nor shall it authorize or permit any of its
directors, officers or employees or any investment banker, financial advisor,
attorney, accountant or other representative retained by it or any of its
Subsidiaries to, directly or indirectly through another Person, (i) solicit,
initiate or knowingly encourage (including by way of furnishing information),
or knowingly take any other action to facilitate, the making of any proposal
that constitutes a Sprint Competing Proposal or (ii) participate in any
discussions or negotiations regarding any Sprint Competing Proposal; provided,
however, that if, at any time during the period commencing on the 61st day
after the date hereof and ending on the date the Required Sprint Vote is
obtained (the "Sprint Applicable Period"), the Board of Directors of Sprint,
in the exercise of its fiduciary duties, determines in good faith, after
consultation with outside counsel, that to do otherwise would not be in the
best interests of Sprint's stockholders, Sprint and its representatives may,
in response to a Sprint Superior Proposal which did not result from a breach
of this Section 5.4(a), and subject to providing prior or contemporaneous
notice of its decision to take such action to MCI WorldCom, (x) furnish
information with respect to Sprint and its Subsidiaries to any Person making a
Sprint Superior Proposal pursuant to a customary confidentiality agreement (as
determined by Sprint after consultation with its outside counsel) and (y)
participate in discussions or negotiations regarding such Sprint Superior
Proposal. This Section 5.4 is subject to Section 5.4 of the Sprint Disclosure
Schedule. For purposes of this Agreement, "Sprint Competing Proposal" means
any bona fide proposal or offer from any Person relating to any direct or
indirect acquisition or purchase of 20% or more of the assets of Sprint and
its Subsidiaries, taken as a whole, or 20% or more of the combined voting
power of the shares of Sprint Common Stock, any tender offer or exchange offer
that if consummated would result in any Person beneficially owning 20% or more
of the combined voting power of the shares of Sprint Common Stock, or any
merger, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving Sprint or any of its Subsidiaries
in which the other party thereto or its stockholders will own 20% or more of
the combined voting power of the parent entity resulting from any such
transaction, other than the transactions contemplated by this Agreement. For
purposes of this Agreement, a "Sprint Superior Proposal" means (i) any
proposal made by a third party relating to any direct or indirect acquisition
or purchase of 50% or more of the assets of Sprint and its Subsidiaries, taken
as a whole, or 50% or more of the combined voting power of the shares of
Sprint Common Stock, any tender offer or

exchange offer that if consummated would result in any Person beneficially
owning 50% or more of the combined voting power of the shares of Sprint Common
Stock or any merger, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving Sprint or any of its
Subsidiaries in which the other party thereto or its stockholders will own 40%
or more of the combined voting power of the parent entity resulting from any
such transaction and (ii) otherwise on terms which the Board of Directors of
Sprint determines in its good faith judgment (based on the advice of a
financial advisor of nationally recognized reputation), taking into account
the Person making the proposal and the legal, financial, regulatory and other
aspects of the proposal deemed appropriate by the Board of Directors of
Sprint, (x) would be more favorable than the Merger to Sprint's stockholders
taken as a whole, (y) is reasonably capable of being completed and (z) for
which financing, to the extent required, is then committed or is reasonably
capable of being obtained by such third party.

          (b) Neither the Board of Directors of Sprint nor any committee
thereof shall (i) withdraw, or propose publicly to withdraw, in a manner
adverse to MCI WorldCom, the approval or recommendation by such Board of
Directors or such committee of the Merger or this Agreement, (ii) subject to
Section 5.4(d), modify, or propose publicly to modify, in a manner adverse to
MCI WorldCom, the approval or recommendation by such Board of Directors or
such committee of the Merger or this Agreement, (iii) approve or recommend, or
propose publicly to approve or recommend, any Sprint Competing Proposal or
(iv) approve or recommend, or propose to approve or recommend, or execute or
enter into, any letter of intent, agreement in principle, merger agreement,
acquisition agreement, option agreement or other similar agreement or propose
publicly or agree to do any of the foregoing (each, a "Sprint Acquisition
Agreement") related to any Sprint Competing Proposal. Notwithstanding the
foregoing, during the Sprint Applicable Period, in response to a Sprint
Superior Proposal which did not result from a breach of Section 5.4(a), if the
Board of Directors of Sprint, in the exercise of its fiduciary duties,
determines in good faith, after consultation with outside counsel, that to do
otherwise would not be in the best interests of Sprint's stockholders, the
Board of Directors of Sprint may (x) modify or propose publicly to modify, in
a manner adverse to MCI WorldCom, the approval or recommendation of the Merger
or this Agreement by the Board of Directors of Sprint and/or (y) terminate
this Agreement (and concurrently with or after such termination, if it so
chooses, cause Sprint to enter into any Sprint Acquisition Agreement with
respect to any Sprint Superior Proposal), but, in the case of clause (y), only
at a time that is during the Sprint Applicable Period and is after the fourth
Business Day (or the second calendar day in the case of a material amendment
to a Sprint Superior Proposal) following MCI WorldCom's receipt of written
notice advising MCI WorldCom that the Board of Directors of Sprint is prepared
to accept a Sprint Superior Proposal (or any material amendment thereto),
specifying the material terms and conditions of such Sprint Superior Proposal
(or any material amendment thereto) and identifying the Person making such
Sprint Superior Proposal (or any material amendment thereto).

          (c) In addition to the obligations of Sprint set forth in paragraphs
(a) and (b) of this Section 5.4, Sprint shall promptly advise MCI WorldCom of
any Sprint Competing Proposal or any inquiry or request for information
relating thereto, the material terms and conditions of such request or Sprint
Competing Proposal and the identity of the Person making such request or
Sprint Competing Proposal. Sprint will promptly keep MCI WorldCom reasonably
informed of the status (including amendments) of any such request or Sprint
Competing Proposal.

          (d) Nothing contained in this Section 5.4 shall prohibit Sprint from
taking and disclosing to its stockholders a position contemplated by Rule
14d-9 or 14e-2 promulgated under the Exchange Act or from making any
disclosure to Sprint's stockholders if, in the good faith judgment of the
Board of Directors of Sprint, after consultation with outside counsel, failure
so to disclose would be inconsistent with its obligations under applicable
law; provided, however, that, subject to Section 5.4(b), neither Sprint nor
its Board of Directors nor any committee thereof shall withdraw, or propose
publicly to withdraw, its position with respect to this Agreement or the
Merger or approve or recommend, or propose publicly to approve or recommend, a
Sprint Competing Proposal.

any proposal that constitutes an MCI WorldCom Competing Proposal or (ii)
participate in any discussions or negotiations regarding any MCI WorldCom
Competing Proposal; provided, however, that if, at any time during the period
commencing on the 61st day after the date hereof and ending on the date
Required MCI WorldCom Vote is obtained (the "MCI WorldCom Applicable Period"),
the Board of Directors of MCI WorldCom, in the exercise of its fiduciary
duties, determines in good faith, after consultation with outside counsel,
that to do otherwise would not be in the best interests of MCI WorldCom's
shareholders, MCI WorldCom and its representatives may, in response to an MCI
WorldCom Superior Proposal which did not result from a breach of this Section
5.5(a), and subject to providing prior or contemporaneous notice of its
decision to take such action to Sprint, (x) furnish information with respect
to MCI WorldCom and its Subsidiaries to any Person making an MCI WorldCom
Superior Proposal pursuant to a customary confidentiality agreement (as
determined by MCI WorldCom after consultation with its outside counsel) and
(y) participate in discussions or negotiations regarding such MCI WorldCom
Superior Proposal. For purposes of this Agreement, "MCI WorldCom Competing
Proposal" means any bona fide proposal or offer from any Person relating to
any direct or indirect acquisition or purchase of 20% or more of the assets of
MCI WorldCom and its Subsidiaries, taken as a whole, or 20% or more of the

MCI WorldCom or any of its Subsidiaries in which (1) the other party thereto
or its shareholders will own 50% or more of the combined voting power of the
shares of the parent entity resulting from any such transaction and (2)
representatives of such other party shall represent a majority of the Board of
Directors of such parent entity, and (ii) otherwise on terms which the Board

committed or is reasonably capable of being obtained by such third party.

          (b) Neither the Board of Directors of MCI WorldCom nor any committee
thereof shall (i) withdraw, or propose publicly to withdraw, in a manner

Agreement") related to any MCI WorldCom Competing Proposal. Notwithstanding
the foregoing, during the MCI WorldCom Applicable Period, in response to an
MCI WorldCom Superior Proposal which did not result from a breach of Section

MCI WorldCom Acquisition Agreement with respect to any MCI WorldCom Superior
Proposal), but, in the case of clause (y), only at a time that is during the
MCI WorldCom Applicable Period and is after the fourth Business Day (or the

informed of the status (including amendments) of any such request or MCI
WorldCom Competing Proposal.

          (d) Nothing contained in this Section 5.5 shall prohibit MCI
WorldCom from taking and disclosing to its shareholders a position
contemplated by Rule 14d-9 or 14e-2 promulgated under the Exchange Act or from
making any disclosure to MCI WorldCom's shareholders if, in the good faith
judgment of the Board of Directors of MCI WorldCom, after consultation with
outside counsel, failure so to disclose would be inconsistent with its
obligations under applicable law; provided, however, that, subject to Section
5.5(b), neither MCI WorldCom nor its Board of Directors nor any committee
thereof shall withdraw, or propose publicly to withdraw, its position with
respect to this Agreement or the Merger or approve or recommend, or propose
publicly to approve or recommend, an MCI WorldCom Competing Proposal.

following:

          (i) adjust the terms of all outstanding Sprint Stock Options (each,
     as so adjusted, an "Adjusted Option"), whether vested or unvested, as
     necessary to provide that, at the Effective Time, each Sprint Stock
     Option outstanding immediately prior to the Effective Time shall be
     amended and converted, on the same terms and conditions as were
     applicable under such Sprint Stock Option, as follows:

               (A) each Sprint Stock Option to acquire shares of Sprint FON
          Stock will be converted into an option to acquire the number of
          shares of MCI WorldCom Common Stock determined by multiplying the
          number of shares of Sprint FON Stock subject to such Sprint Stock
          Option by the FON Exchange Ratio (rounded up to the nearest whole
          share) at an exercise price determined by dividing the exercise
          price set forth in such Sprint Stock Option by the FON Exchange
          Ratio (rounded up to the nearest whole cent); and

               (B) each Sprint Stock Option to acquire shares of any class of
          Sprint PCS Stock will be converted into an option to acquire:

                         (x) an equivalent number of shares of MCI WorldCom
                    Series 1 PCS Stock at the same exercise price as the
                    exercise price for such Sprint PCS Stock plus

                         (y) an amount of MCI WorldCom Common Stock for no
                    additional consideration equal to the number of shares of
                    such Sprint PCS Stock subject to such Sprint Stock Option
                    multiplied by the PCS Exchange Ratio, (rounded up to the
                    nearest whole share) (the "MCI WorldCom Common Stock
                    Option Shares"), where such option shall automatically be
                    exercised (as part of the exercise of the option to
                    acquire MCI WorldCom Series 1 PCS Stock described in the
                    preceding clause (x)) for a number of shares of MCI

                    acquire MCI WorldCom Series 1 PCS Stock is exercised, and
                    where the number of shares of MCI WorldCom Common Stock to
                    be acquired upon such exercise shall:

                              (1) equal "Z" (rounded up to the nearest whole
                         share), where "Z" equals (i) the number of shares of
                         MCI WorldCom Series 1 PCS Stock to be acquired
                         pursuant to such exercise of such option multiplied
                         by (ii) the PCS Exchange Ratio; or

                              (2) equal the number of shares of MCI WorldCom
                         Common Stock which remain subject to such option, if
                         such exercise is for all the shares of MCI WorldCom
                         Series 1 PCS Stock which remain subject to such
                         option;

                    ; provided, however, that the maximum number of shares of
                    MCI WorldCom Common Stock issuable pursuant to all such
                    exercises of an Adjusted Option described in this Section
                    5.6(a)(i)(B) shall not in the aggregate exceed the number
                    of MCI WorldCom Common Stock Option Shares; and

          (ii) make such other changes to the Sprint Stock Option Plans as MCI
WorldCom and Sprint may agree are appropriate to give effect to the Merger.

          (b) The adjustments provided in this Section 5.6 with respect to any
Sprint Stock Options to which Section 421(a) of the Code applies shall be and
are intended to be effected in a manner which is consistent with Section
424(a) of the Code.

          (c) Prior to the Effective Time, MCI WorldCom shall take all
necessary actions (including, if required to comply with Section 162(m) of the
Code (and the regulations thereunder) or applicable law or rule of Nasdaq,
obtaining the approval of its shareholders at the next regularly scheduled
annual meeting of MCI WorldCom following the Effective Time) to assume as of
the Effective Time all obligations undertaken by, or on behalf of, Sprint
under Section 5.6(a) and to adopt at the Effective Time the Sprint Stock
Option Plans and each Adjusted Option and to take all other action called for
in this Section 5.6, including the reservation, issuance and listing of MCI
WorldCom Capital Stock in a number at least equal to the number of shares of
MCI WorldCom Common Stock that will be subject to the Adjusted Options.

          (d) As soon as practicable following the Effective Time, MCI
WorldCom shall prepare and file with the SEC a registration statement on Form
S-8 (or another appropriate form) registering a number of shares of MCI
WorldCom Common Stock equal to the number of shares subject to the Adjusted
Options. Such registration statement shall be kept effective (and the current
status of the prospectus or prospectuses required thereby shall be maintained)
at least for so long as any Adjusted Options or any unsettled awards granted
under the Sprint Stock Option Plans after the Effective Time may remain
outstanding.

          (e) As soon as practicable after the Effective Time, MCI WorldCom
shall deliver to the holders of the Sprint Stock Options appropriate notices
setting forth such holders' rights pursuant to the respective Sprint Stock
Option Plans and the agreements



<PAGE>


                                                                            42

evidencing the grants of such Sprint Stock Options and that such Sprint Stock
Options and agreements shall be assumed by MCI WorldCom and shall continue in
effect on the same terms and conditions (subject to the adjustments required
by this Section 5.6 after giving effect to the Merger).

          (f) Except as otherwise expressly provided in this Section 5.6 and
except to the extent required under the respective terms of the Sprint Stock
Options, all restrictions or limitations on transfer and vesting with respect
to the Sprint Stock Options awarded under the Sprint Stock Option Plans or any
other plan, program or arrangement of Sprint or any of its Subsidiaries, to
the extent that such restrictions or limitations shall not have already
lapsed, and all other terms thereof, shall remain in full force and effect
with respect to such options after giving effect to the Merger and the
assumption by MCI WorldCom as set forth above.

          5.7 Employee Matters. (a) During the one-year period following the
Effective Time (the "Transition Period"), MCI WorldCom shall maintain employee
benefit plans, programs and policies for the employees of Sprint and its
Subsidiaries which, in the aggregate, are substantially comparable to the
employee benefit plans, programs and policies provided by Sprint and its
Subsidiaries before the Effective Time (other than Sprint's Employees Stock
Purchase Plan). Furthermore, no employee of Sprint or a Subsidiary of Sprint
shall have his or her base hourly rate of pay, base salary or bonus
opportunity reduced during the Transition Period except to the extent such
reduction is called for as a result of a violation of MCI WorldCom's generally
applicable policies or a failure to satisfy MCI WorldCom's generally
applicable performance standards for similarly situated MCI WorldCom
employees. The participant accounts in each unfunded plan, program or policy
of Sprint and each Subsidiary of Sprint which are designed to track the
performance of Sprint Capital Stock but which only pay benefits in cash shall
be converted at the Effective Time to accounts which track the performance of
the corresponding MCI WorldCom Capital Stock based upon the principles set
forth in this Agreement for converting Sprint Capital Stock to MCI WorldCom
Capital Stock except that there shall be no rounding up or down as part of
such conversions.

          (b) During the one-year period following the Transition Period, the
employees of Sprint and each Subsidiary of Sprint shall be eligible to
participate in employee benefit plans, programs and policies which, in the
aggregate, are substantially comparable to the employee benefit plans,
programs and policies maintained by MCI WorldCom for similarly situated
employees. Each employee of Sprint and each Subsidiary of Sprint shall receive
full credit under each applicable MCI WorldCom plan, program or policy for his
or her service as an employee of Sprint and any Subsidiary of Sprint on the
same basis that he or she would have received such credit if such service had
been completed as an employee of MCI WorldCom for purposes of satisfying any
service requirement to participate in such plan, program or policy (including
any plan, program or policy which provides post-retirement medical benefits)
and any service requirement to receive a non-forfeitable interest in the
benefits under such plan, program or policy. Furthermore, if any such MCI
WorldCom plan, program or policy has any active employment requirements,
pre-existing condition requirements, co-pay, coinsurance or deductible
requirements in effect for a year and an employee of Sprint or a Subsidiary of
Sprint had satisfied (or had made payments towards satisfying) such
requirements for a part of such year as a participant in a Sprint plan,
program or policy, such employee shall receive full credit for satisfying (or
for payments made towards satisfying) such requirements in the MCI WorldCom
plan, program or policy for such



<PAGE>


                                                                            43

year when he or she begins to participate in such plan, program or policy and
any such co-pay, coinsurance or deductible requirements for such year under
the MCI WorldCom plan, program or policy shall be no greater than the co-pay,
coinsurance or deductible requirement under the Sprint plan, program or policy
for such year.

          (c) MCI WorldCom and Sprint will implement the provisions relating
to Sprint employee matters set forth in Section 5.7 of the Sprint Disclosure
Schedule.

          5.8 Fees and Expenses. (a) Whether or not the Merger is consummated,
all Expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such Expenses, except
Expenses incurred in connection with the filing, printing and mailing of the
Form S-4 and the Joint Proxy Statement/Prospectus (including SEC filing fees)
and the filing fees for the premerger notification and report forms under the
HSR Act and for filings with the European Commission, which shall be shared
equally by MCI WorldCom and Sprint. As used in this Agreement, "Expenses"
includes all out-of-pocket expenses (including all fees and expenses of
counsel, accountants, investment bankers, experts and consultants to a party
hereto and its affiliates) incurred by a party or on its behalf in connection
with or related to the authorization, preparation, negotiation, execution and
performance of this Agreement and the transactions contemplated hereby,
including the preparation, printing, filing and mailing of the Form S-4 and
the Joint Proxy Statement/Prospectus and the solicitation of stockholder
approvals and all other matters related to the transactions contemplated
hereby.

          (b) If (1) prior to the date the Required Sprint Vote is obtained a
Sprint Competing Proposal shall have been made to Sprint or any of its
Subsidiaries or shall have been made directly to the stockholders of Sprint
generally or any Person shall have publicly announced an intention (whether or
not conditional) to make a Sprint Competing Proposal and thereafter this
Agreement is terminated by either MCI WorldCom or Sprint pursuant to Section
7.1(b) without a Sprint Stockholders Meeting having occurred or 7.1(d)(i) or
(2) this Agreement is terminated (i) by Sprint pursuant to Section 7.1(e) or
(ii) by MCI WorldCom pursuant to Section 7.1(j), then Sprint shall promptly,
but in no event later than the date of such termination, pay MCI WorldCom a
fee equal to $2.5 billion (the "Termination Fee"), payable by wire transfer of
same day funds; provided, however, that no Termination Fee shall be payable to
MCI WorldCom pursuant to clause (1) or (2)(ii) of this paragraph (b) unless
and until within 12 months of such termination Sprint or any of its
Subsidiaries enters into any Sprint Acquisition Agreement with respect to, or
approves or consummates, any Sprint Competing Proposal (for the purposes of
the foregoing proviso the term "Sprint Competing Proposal" shall mean a Sprint
Superior Proposal pursuant to clause (i) (without giving effect to clause
(ii)) of the definition thereof in Section 5.4(a), in which event the
Termination Fee shall be payable upon the first to occur of such events.
Sprint acknowledges that the agreements contained in this Section 5.8(b) are
an integral part of the transactions contemplated by this Agreement, and that,
without these agreements, MCI WorldCom would not enter into this Agreement;
accordingly, if Sprint fails promptly to pay the amount due pursuant to this
Section 5.8(b), and, in order to obtain such payment, MCI WorldCom commences a
suit which results in a judgment against Sprint for the fee set forth in this
Section 5.8(b), Sprint shall pay to MCI WorldCom its costs and expenses
(including attorneys' fees and expenses) in connection with such suit,
together with interest on the amount of the fee at the prime rate of Citibank,
N.A. in effect on the date such payment was required to be made.

          (c) If (1) prior to the date the Required MCI WorldCom Vote is
obtained an MCI WorldCom Competing Proposal shall have been made to MCI
WorldCom or any of its Subsidiaries or shall have been made directly to the
shareholders of MCI WorldCom generally or any Person shall have publicly
announced an intention (whether or not conditional) to make an MCI WorldCom
Competing Proposal and thereafter this Agreement is terminated by either MCI
WorldCom or Sprint pursuant to Section 7.1(b) without an MCI WorldCom
Shareholders Meeting having occurred or 7.1(d)(ii) or (2) this Agreement is
terminated (i) by MCI WorldCom pursuant to Section 7.1(f) or (ii) by Sprint
pursuant to Section 7.1(i), then MCI WorldCom shall promptly, but in no event
later than the date of such termination, pay Sprint the Termination Fee,
payable by wire transfer of same day funds; provided, however, that no
Termination Fee shall be payable to Sprint pursuant to clause (1) or (2)(ii)
of this paragraph (c) unless and until within 12 months of such termination
MCI WorldCom or any of its Subsidiaries enters into any MCI WorldCom
Acquisition Agreement with respect to, or approves or consummates, any MCI
WorldCom Competing Proposal (for the purposes of the foregoing proviso the
term "MCI WorldCom Competing Proposal" shall mean an MCI WorldCom Superior
Proposal pursuant to clause (i) (without giving effect to clause (ii)) of the
definition thereof in Section 5.5(a), in which event the Termination Fee shall
be payable upon the first to occur of such events. MCI WorldCom acknowledges
that the agreements contained in this Section 5.8(c) are an integral part of
the transactions contemplated by this Agreement, and that, without these
agreements, Sprint would not enter into this Agreement; accordingly, if MCI
WorldCom fails promptly to pay the amount due pursuant to this Section 5.8(c),
and, in order to obtain such payment, Sprint commences a suit which results in
a judgment against MCI WorldCom for the fee set forth in this Section 5.8(c),
MCI WorldCom shall pay to Sprint its costs and expenses (including attorneys'
fees and expenses) in connection with such suit, together with interest on the
amount of the fee at the prime rate of Citibank, N.A. in effect on the date
such payment was required to be made.

          5.9 Indemnification, Exculpation and Insurance. (a) MCI WorldCom
agrees that all rights to indemnification and exculpation from liabilities for
acts or omissions occurring at or prior to the Effective Time now existing in
favor of the current or former directors or officers of Sprint and its
Subsidiaries as provided in their respective articles of incorporation or
by-laws (or comparable organizational documents) and any indemnification
agreements of Sprint, the existence of which does not constitute a breach of
this Agreement, shall be assumed by MCI WorldCom, as the Surviving Corporation
in the Merger, without further action, as of the Effective Time and shall
survive the Merger and shall continue in full force and effect in accordance
with their terms.

          (b) In the event that MCI WorldCom or any of its successors or
assigns (i) consolidates with or merges into any other Person and is not the
continuing or surviving corporation or entity of such consolidation or merger
or (ii) transfers or conveys all or substantially all of its properties and
assets to any Person, then, and in each such case, proper provision will be
made so that the successors and assigns of MCI WorldCom assume the obligations
set forth in this Section 5.9.

          (c) For six years after the Effective Time, MCI WorldCom shall
maintain in effect Sprint's current directors' and officers' liability
insurance covering acts or omissions occurring prior to the Effective Time
with respect to those Persons who are currently covered by Sprint's directors'
and officers' liability insurance policy on terms

                                                                            45

with respect to such coverage and amount no less favorable than those of such
policy in effect on the date hereof; provided, however, that in no event shall
MCI WorldCom be required to expend in any one year an amount in excess of 200%
of the annual premiums currently paid by Sprint for such insurance; and,
provided, further, that if the annual premiums of such insurance coverage
exceed such amount, MCI WorldCom shall be obligated to obtain a policy with
the greatest coverage available for such amount.

          5.10 Sprint Rights Agreement. The Board of Directors of Sprint shall
take all action to the extent necessary (including amending the Sprint Rights
Agreement) in order to render the Sprint Rights inapplicable to the Merger and
the other transactions contemplated by this Agreement. Except in connection
with the foregoing sentence or, with respect to a Sprint Superior Proposal,
concurrently with or after a termination of this Agreement by Sprint in
accordance with Section 5.4(b), the Board of Directors of Sprint shall not,
without the prior written consent of MCI WorldCom, (a) amend the Sprint Rights

inapplicable to the Merger and the other transactions contemplated by this
Agreement. Except in connection with the foregoing sentence or, with respect
to an MCI WorldCom Superior Proposal, concurrently with or after a termination
of this Agreement by MCI WorldCom in accordance with Section 5.5(b), the Board
of Directors of MCI WorldCom shall not, without the prior written consent of
Sprint, (a) amend the MCI WorldCom Rights Agreement or (b) take any action
with respect to, or make any determination under, the MCI WorldCom Rights
Agreement, including a redemption of the MCI WorldCom Rights, in each case in
order to facilitate an MCI WorldCom Competing Proposal. Notwithstanding the
foregoing, MCI WorldCom may amend the MCI WorldCom Rights Agreement to effect
a transaction permitted by Section 4.2(c) of this Agreement.

          5.12 Public Announcements. Sprint and MCI WorldCom shall use all
reasonable efforts to develop a joint communications plan and each party shall
use all reasonable efforts (i) to ensure that all press releases and other
public statements with respect to the transactions contemplated hereby shall
be consistent with such joint communications plan, and (ii) unless otherwise
required by applicable law or by obligations pursuant to any listing agreement
with or rules of any securities exchange, to consult with each other before
issuing any press release or otherwise making any public statement with
respect to this Agreement or the transactions contemplated hereby.

          5.13 Listing. MCI WorldCom shall use its reasonable best efforts to

          5.15 Affiliate Letter. On or prior to the date of the Sprint
Stockholders Meeting, Sprint will deliver to MCI WorldCom a letter (the
"Sprint Affiliate Letter") identifying all Persons who are, or may be,
"affiliates" of Sprint for purposes of Rule 145 under the Securities Act
("Rule 145"). On or prior to the Closing Date, Sprint will use its reasonable
efforts to deliver on behalf of each Person identified as an "affiliate" in
the Sprint Affiliate Letter a written agreement in connection with
restrictions on affiliates under Rule 145.

          5.16 Tax Treatment. Each of MCI WorldCom and Sprint shall use
reasonable efforts to cause the Merger to qualify as a "reorganization" under
the provisions of Section 368 of the Code and to obtain the opinions of
counsel referred to in Sections 6.2(c) and 6.3(c), including the execution of
the letters of representation referred to therein updated as necessary. Sprint
and MCI WorldCom and their respective Subsidiaries shall treat the MCI
WorldCom Common Stock, MCI WorldCom PCS Stock, MCI WorldCom Series FT Common
Stock, MCI WorldCom Series DT Common Stock, MCI WorldCom Series 2 Common Stock
and MCI WorldCom Series 3 Common Stock (together, the "MCI WorldCom Relevant
Stock") received in the Merger by holders of Sprint Common Stock as property
permitted to be received under Section 354 of the Code without the recognition
of gain. Each of Sprint and MCI WorldCom covenants and agrees to, and agrees
to cause its affiliates to, vigorously and in good faith defend all challenges
to the treatment of the reorganization as described in this Section 5.16,
including any such challenge to the treatment of the MCI WorldCom Relevant
Stock as property permitted to be received under Section 354 of the Code
without the recognition of gain. Each of Sprint and MCI WorldCom agrees that
if it becomes aware of any such fact or circumstance that is reasonably likely
to prevent the Merger from qualifying as a reorganization described in Section
368(a) of the Code, including any such fact or circumstance that is reasonably
likely to prevent the MCI WorldCom Relevant Stock from being treated as
property permitted to be received under Section 354 of the Code without the
recognition of gain, it will promptly notify the other party in writing.

          5.17 Assumption Agreement and Supplemental Indentures. Prior to or
at the Effective Time, MCI WorldCom will execute and deliver (a) a written
instrument to Sprint evidencing its obligation to deliver to each holder of a
warrant granted pursuant to one of the Warrant Agreements other securities,
cash or other assets as such holder may be entitled to purchase and the other
obligations under the applicable Warrant Agreement, and (b) a supplemental
indenture to each of the trustees with respect to the indentures named in
Section 5.17 of the Sprint Disclosure Schedule, in form satisfactory to each
such trustee, as required under such indentures.

          5.18 Other Actions. Sprint will use reasonable efforts to cooperate
with any request by MCI WorldCom to transfer certain assets of Sprint to any
Subsidiary of Sprint, so long as such transfer(s) (a) would be permitted by
applicable regulations, laws and contracts, (b) would not, individually or in
the aggregate, adversely affect Sprint and (c) would be executed by Sprint at
any time (as determined by Sprint) prior to the Effective Time.

except where the failure of such representations and warranties to be so true

substantially in the form of Appendices 3 and 4, respectively, and updated as
necessary. The opinions shall be in substantially the same form as Appendix 1.

of Sprint to effect the Merger are subject to the satisfaction of, or waiver
by Sprint, on or prior to the Closing Date of the following additional

of MCI WorldCom set forth in this Agreement shall be true and correct on the
date of this Agreement and as of the Closing Date, as if made at and as of
such time (except to the extent expressly made as of an earlier date, in which
case as of such date), except for changes expressly permitted under Article IV
and except where the failure of such representations and warranties to be so
true and correct (without giving effect to any limitation as to "materiality"
or "Material Adverse Effect" set forth therein), individually or in the
aggregate, does not have, and is not reasonably likely to have, a Material
Adverse Effect on MCI WorldCom, and (ii) the representations and warranties of
MCI WorldCom set forth in Section 3.2(b)(i), (ii) and (iii) shall be true and
correct in all material respects on the date of this Agreement, and as of the

opinions, counsel to Sprint shall be entitled to rely upon representations of
officers of MCI WorldCom and Sprint substantially in the form of Appendices 3
and 4, respectively, and updated as necessary. The opinions shall be in
substantially the same form as Appendix 2.

          Notwithstanding anything else contained in this Agreement, the right
to terminate this Agreement under this Section 7.1 shall not be available to
any party (a) that is in material breach of its obligations hereunder or (b)

by action taken or authorized by their respective Boards of Directors, at any
time before or after approval of the matters presented in connection with the
Merger by the stockholders of Sprint and MCI WorldCom, but, after any such

rules of any relevant stock exchange requires further approval by such
stockholders without such further approval. This Agreement may not be amended
except by an instrument in writing signed on behalf of each of the parties
hereto.

          7.4 Extension; Waiver; Consent. At any time prior to the Effective

MCI WORLDCOM                                                   SPRINT

FOR IMMEDIATE RELEASE

             MCI WORLDCOM AND SPRINT CREATE PRE-EMINENT GLOBAL
                  COMMUNICATIONS COMPANY FOR 21st CENTURY

      Major Force in Fastest Growing Areas of Communications Services

            Provides Broadband Access Alternative For Customers

            Expanded Scale Brings Customers Innovation and Value


CLINTON, MS, and KANSAS CITY, MO - (October 5, 1999) - MCI WorldCom
(NASDAQ:WCOM) and Sprint (NYSE:FON, PCS) today announced that the boards of
directors of both companies have approved a definitive merger agreement.
The merger creates the pre-eminent global communications company for the
21st century - a dramatically more effective competitor. The combined
company, to be called WorldCom, will provide a full range of services to
residential and business customers on its owned, end-to-end,
state-of-the-art network infrastructure. WorldCom will be a leader in the
fastest growing areas of global communications services, offering
innovative broadband, "all distance" services to businesses and homes, and
nationwide digital wireless voice and data services.

Under the agreement, each share of Sprint FON Group (NYSE:FON) will be
exchanged for $76.00 of MCI WorldCom common stock, subject to a collar. In
addition, each share of Sprint PCS Group (NYSE:PCS) will be exchanged for
one share of a new WorldCom PCS tracking stock and 0.1547 shares of MCI
WorldCom common stock. The terms of the WorldCom PCS tracking stock will be
equivalent to those of Sprint PCS and will track the performance of the
company's PCS business. The total value of the transaction is approximately
$129 billion ($115 billion in equity and $14 billion in debt and preferred
stock). The merger will be tax-free to shareholders and accounted for as a
purchase.

The transaction is expected to be essentially non-dilutive to WorldCom's
earnings per share before goodwill amortization ("cash earnings"). The
combination creates significant cost savings that will allow the new
company to compete aggressively in both the business and consumer markets
and to aggressively invest in new technologies such as broadband access and
next generation wireless.

MCI WorldCom has a proven track record of identifying and realizing cost
savings. The companies estimate that annual cash operating cost savings of
$1.9 billion are achievable in 2001 - the first full year of operation -
increasing to $3.0 billion annually by 2004. These cost savings are
anticipated to result from better utilization of the combined networks and
other operational savings. Capital expenditure savings of $1.3 billion a
year are expected in 2001 and beyond, primarily as a result of economies of
scale and procurement efficiencies.

In addition to cost savings, the transaction offers the prospect of
significant revenue benefits as a result of churn reduction from bundling a
broader range of services, cross

selling to a larger customer base and the development of new services. MCI
WorldCom and Sprint have also agreed to enter into commercial business
arrangements between the two companies prior to closing.

WorldCom will have the capital, proven marketing strength and
state-of-the-art networks to compete more effectively against the incumbent
carriers, domestically and abroad. The combination of MCI WorldCom and
Sprint will:

o    Generate pro forma 1999 revenues of more than $50 billion, a market
     enterprise value of approximately $290 billion and significant
     operations in more than 65 countries;

o    Offer a unique nationwide broadband access alternative to both cable
     and traditional telephony through a combination of Digital Subscriber
     Line (DSL) facilities and fixed wireless access using the combined
     company's nationwide MMDS spectrum;

o    Continue to lead the industry with innovative service offerings for
     consumer and business customers alike in an increasingly competitive
     global marketplace. The combined company, operating with extensive
     local facilities as well as substantial scale, will have the
     capability to bring innovative broadband solutions to local customers
     in the United States and abroad; and

o    Be a formidable wireless competitor in the United States - with more
     than 4 million PCS subscribers, leading the industry in growth; and
     1.7 million paging and advanced messaging customers.

Bernard J. Ebbers, president and chief executive officer of MCI WorldCom,
said, "The economics of the combination are particularly compelling and
WorldCom will have the capital, proven marketing strength and
state-of-the-art networks to compete more effectively against the incumbent
carriers domestically and abroad. Sprint's ability to offer a full range of
wireline and wireless services will benefit our customers and fuel
sustained double-digit revenue and earnings growth. The merger with Sprint
is particularly timely as wireless communications emerges as a critical
component of full service offerings. Increasingly, wireless will be used
for Internet access and data services, two areas in which both companies
excel. Gaining an all-digital nationwide footprint with common technology
and spectrum that delivers next generation capabilities is of paramount
importance."

William T. Esrey, chairman and chief executive officer of Sprint, said,
"From building the first nationwide fiber optic network to creating the
nation's first all-digital, nationwide PCS wireless system, Sprint has been
a pioneer in the communications industry. Sprint has utilized technology
and marketing innovation to deliver value to consumers and businesses
worldwide. Sprint ION will enable the merged company to provide end-to-end
integrated broadband services for the home, as well as for the business
market, as an alternative to traditional cable and telephony providers. The
combined strengths of WorldCom and Sprint will allow us to bring customers
a suite of fully integrated broadband and wireless all-distance services
providing consumers and businesses with exciting competitive alternatives."

and respected management team. The management team will consist of top

Esrey will become chairman of WorldCom. Mr. Ebbers will be president and
chief executive officer of the combined company. The board of directors of
the combined company will have 16 members, 10 from MCI WorldCom and six

stockholders as well as approvals from the Federal Communications
Commission, the Justice Department, various state government bodies and
foreign antitrust authorities. The companies anticipate that the merger
will close in the second half of 2000.

The actual number of shares of MCI WorldCom common stock to be exchanged
for each Sprint FON Group share will be determined based on the average
trading prices prior to the closing, but will not be less than 0.9400
shares (if MCI WorldCom's average stock price exceeds $80.85) or more than
1.2228 shares (if MCI WorldCom's average stock price is less than $62.15).
