any Law (whether temporary, preliminary or permanent) that is in effect and

                  (i) As soon as practicable, but in no event later than

shall, on a basis consistent with GAAP consistently applied, prepare and deliver
to BellSouth a statement showing (x) the liabilities of each BellSouth
Additional Subsidiary calculated in a manner consistent with GAAP and (y) the
current assets (including cash and cash equivalents) of such BellSouth
Additional Subsidiary (including for purposes of this calculation the current
assets of only those Subsidiaries that are operating companies) calculated in
accordance with GAAP consistently applied, each as of the BellSouth Additional
Closing Date. In the event of any disputes over the calculation prepared by
Newco, the procedures set forth in Section 2.11(b) and (c) shall apply. Within
five Business Days following either (i) an agreement by BellSouth and Newco as
to the calculation, or (ii) the determination of the CPA Firm pursuant to
Section 2.11(c), the following payments shall be made:

                                    (A) To the extent the number in (x) above
         exceeds the number in (y) above, such BellSouth Additional Subsidiary
         shall pay to Newco, in cash, the amount by which the number in (x)
         above exceeds the number in (y) above.

                                    (B) To the extent the number in (y) above

                                      -24-
<PAGE>   30
         cash, the amount by which the number in (y) above exceeds the number in
         (x) above.

                  (j) BellSouth shall cause a BellSouth Additional Subsidiary to
own, free and clear of all Encumbrances, at least $1.150 billion in cash and
cash equivalents in a non-operating company as of the Closing Date and shall
maintain at least such level of cash and cash equivalents in such entity through
the BellSouth Additional Closing or, if there is no such closing, until the time
of determination of the BellSouth Additional Subsidiary Value pursuant to
Section 2.10(g).

                  (k) Any payments made pursuant to this Section 2.10 shall be
made according to the procedures set forth in Section 2.11(e).

         2.11 Net Debt. (a) As soon as practicable, but in no event later than
ninety (90) days following the Closing Date, Newco shall, on a basis consistent
with GAAP prepare and deliver to each of SBC and BellSouth a statement showing
the calculation of the Closing Net Debt (the "Calculation"). The Calculation
shall separately set forth the SBC Closing Net Debt and BellSouth Closing Net
Debt.

                  (b) After receipt of the Calculation, SBC and BellSouth shall
each have 60 days to review the Calculation. Newco, SBC and BellSouth shall each
provide the others and their authorized representatives reasonable access during
normal business hours and without significant disruption to their respective
business, to (i) all of their and their Subsidiaries' respective books, records
and employees having relevant information concerning the Calculation and (ii)
the accountants who assisted Newco in preparing the Calculation and such
accountants' relevant supporting workpapers. Unless SBC or BellSouth delivers
written notice to Newco and to SBC or BellSouth, as the case may be, on or prior
to the 60th day after Newco's delivery of the Calculation stating that SBC or
BellSouth, as the case may be, has objections to the Calculation and describing
any such objections with reasonable particularity, SBC and BellSouth shall be
deemed to have accepted and agreed to the Calculation. In addition, any item
included in the Calculation which is not objected to by either SBC or BellSouth
shall be deemed to be accepted by SBC and BellSouth (the "Resolved Items") and
any amounts included within a Resolved Item shall be deemed to be final, binding
and conclusive. If SBC or BellSouth notifies Newco of its objections to the
Calculation, SBC, BellSouth and Newco shall, within 10 days (or such longer
period as the parties may agree) following such notice (the "Resolution
Period"), attempt to resolve their differences, and any written resolution by
them as to any disputed amounts shall be final, binding and conclusive.

                  (c) Any amounts remaining in dispute at the conclusion of the
Resolution Period ("Unresolved Items") shall be submitted to Arthur Andersen LLP
(such firm being referred to as the "CPA Firm") or, if such firm shall be unable
or

                                      -25-
<PAGE>   31
unwilling to serve in such capacity or if the parties shall otherwise mutually
agree, such other nationally recognized firm of independent accountants mutually
agreed by SBC, BellSouth and Newco (and, in such case, such firm shall be deemed
to be the CPA Firm), within 10 days after the expiration of the Resolution
Period. Each Party agrees to execute, if requested by the CPA Firm, an
engagement letter with the CPA Firm containing reasonable terms. All fees and
expenses relating to the work, if any, to be performed by the CPA Firm shall be
borne by all of the parties equally. The CPA Firm shall act as an arbitrator and
not as an expert in determining the Unresolved Items. The CPA Firm's
determination of the Unresolved Items shall be made within 30 days after the
submission of the Unresolved Items to the CPA Firm, and, together with a
calculation of the Closing Working Capital and the Closing Long Term Liabilities
based upon the amount of Resolved Items and the CPA Firm's determinations of the
Unresolved Items, shall be set forth in a written statement delivered to SBC,
BellSouth and Newco by the CPA Firm and shall be final, binding and conclusive
on the parties for all purposes.

                  (d) Within five (5) Business Days following either (i) an
agreement by SBC, BellSouth and Newco as to the Calculation or (ii) the CPA
Firm's determination of the Calculation, the following payments shall be made:

                           (x) If the SBC Closing Net Debt exceeds the Target
                  SBC Net Debt, then SBC shall pay to Newco, in cash, an amount
                  equal to the amount by which the SBC Closing Net Debt exceeds
                  the Target SBC Net Debt. If the BellSouth Closing Net Debt
                  exceeds the Target BellSouth Net Debt, then BellSouth shall
                  pay to Newco, in cash, an amount equal to the amount by which
                  the BellSouth Closing Net Debt exceeds the Target BellSouth
                  Net Debt.

                           (y) If the Target SBC Net Debt exceeds the SBC
                  Closing Net Debt, then Newco shall pay to SBC, in cash, an
                  amount equal to the amount by which the Target SBC Net Debt
                  exceeds the SBC Closing Net Debt. If the Target BellSouth Net
                  Debt exceeds the BellSouth Closing Net Debt, then Newco shall
                  pay to BellSouth, in cash, an amount equal to the amount by
                  which the Target BellSouth Net Debt exceeds the BellSouth
                  Closing Net Debt.

                  (e) Any payments made pursuant to this Section 2.11 shall be
made by wire transfer of immediately available funds to an account indicated in
writing by the party to receive such funds and shall be accompanied by interest
at the prime rate publicly announced from time to time by Bank of America or its
successor calculated on the basis of a year of 360 days for the actual number of
days elapsed, accrued from the Closing Date up to and including the date of
payment.

financial condition, properties, business or results of operations of the SBC
Companies and their Subsidiaries, taken as a whole, with respect to the
BellSouth Companies, a material adverse effect on the financial condition,
properties, business or results of operations of the BellSouth Companies and
their Subsidiaries taken as a whole, and, with respect to Newco, a material

         notices being the "SBC Required Consents"), no notices, reports or
         other filings are required to be made by it or its Subsidiaries with,
         nor are any consents, registrations, approvals, permits or
         authorizations required to be obtained by it or its Subsidiaries from,
         any Governmental Entity, in connection with the execution and delivery
         of this Agreement by it and the consummation by it of the SBC
         Contribution or the SBC Additional Closings hereby, except those that
         the failure to make or obtain would not, individually or in the
         aggregate, be reasonably likely to have a Material Adverse Effect on
         the SBC Companies or prevent, materially delay or materially impair its
         ability to consummate the transactions contemplated by this Agreement.

                           (ii) The execution, delivery and performance of this
         Agreement by it do not, and the consummation by it of the transactions
         contemplated hereby will not, constitute or result in (A) a breach or

         owned by a SBC Company or the applicable Subsidiary free and clear of
         all Encumbrances, and all equity interests are duly authorized, validly

respective businesses only in the ordinary and usual course of such businesses;
(ii) there has not been any change in the financial condition, properties,

Companies; (iii) there has not been any damage, destruction or other casualty

the SBC Companies and their Subsidiaries, whether or not covered by insurance,
which damage, destruction or loss is reasonably likely, individually or in the
aggregate, to have a Material Adverse Effect on the SBC Companies; (iv) there
has not been any sale, transfer, conveyance, lease, creation of an Encumbrance

                  (i)      SBC Employee Benefits.

                           (i) A listing of each bonus, deferred compensation,
         pension, retirement, profit-sharing, thrift, savings, employee stock
         ownership, stock bonus, stock purchase, restricted stock, stock option,
         employment, termination, severance, compensation, medical, health or
         other plan, agreement, policy or arrangement (the "SBC Compensation and
         Benefit Plans") that covers employees, directors, former employees or
         former directors of the SBC Companies or their Subsidiaries and any
         other employee of SBC or a Subsidiary of SBC whose services are
         primarily related (or, for persons who no longer perform such services,
         were related) to the SBC Business (the "SBC Employees") and any trust
         agreements or insurance contracts forming a part of the SBC
         Compensation and Benefit Plans is set forth in Schedule 3.1(i)(i) of
         the SBC Disclosure Letter.

                           (ii) All of the SBC Compensation and Benefit Plans
         are in compliance with their terms and with all applicable Law,
         including the Code and ERISA, except for failures to comply which are
         not, individually or in the aggregate, reasonably likely to have a
         Material Adverse Effect on the SBC Companies. Each of the SBC
         Compensation and Benefit Plans that is an "employee pension benefit
         plan" within the meaning of Section 3(2) of ERISA (a "SBC Pension Plan"
         and collectively, the "SBC Pension Plans") and that is intended to be
         qualified under Section 401(a) of the Code has received a favorable
         determination letter from the IRS, and SBC does not have Knowledge of
         any circumstances likely to result in revocation of any such favorable
         determination letter. There is no pending or, to the Knowledge of SBC,
         threatened claim, audit, investigation, litigation or other proceeding
         relating to the SBC Compensation and Benefit Plans, except for
         proceedings which are not, individually or in the aggregate, reasonably
         likely to have a Material Adverse Effect on the SBC Companies. Neither
         SBC nor any Subsidiary of SBC has engaged in a transaction with respect
         to any of the SBC Compensation and Benefit Plans that, assuming the
         taxable period of such transaction expired as of the date hereof, would
         subject the SBC Companies or any of their Subsidiaries to a material
         tax or penalty imposed by either Section 4975 of the Code or Section
         502 of ERISA.

                           (iii) As of the date hereof, no liability under
         Subtitle C or D of Title IV of ERISA (other than the payment of
         prospective premium amounts to the Pension Benefit Guaranty Corporation
         in the normal course) has been or is expected to be incurred by the SBC
         Companies or any of their Subsidiaries with respect to any ongoing,
         frozen or terminated "single-employer plan," within the meaning of
         Section 4001(a)(15) of ERISA, currently or formerly maintained by any
         of them, or the single-employer plan of any entity which is considered
         one employer with it under Section 4001 of ERISA or Section 414 of the
         Code (its

                                      -31-
<PAGE>   37
         "ERISA Affiliate") (each such single-employer plan, an "ERISA Affiliate
         Plan"). The SBC Companies, their Subsidiaries and their ERISA
         Affiliates have not contributed, or been obligated to contribute, to a
         multiemployer plan under Subtitle E of Title IV of ERISA at any time
         since September 26, 1980. No notice of a "reportable event," within the
         meaning of Section 4043 of ERISA for which the 30-day reporting
         requirement has not been waived, has been required to be filed for any
         of the SBC's Pension Plans or any of its ERISA Affiliate Plans within
         the 12-month period ending on the date hereof or will be required to be
         filed in connection with the transactions contemplated by this
         Agreement.

                           (iv) None of the SBC Pension Plans nor any of SBC's
         ERISA Affiliate Plans has an "accumulated funding deficiency" (whether
         or not waived) within the meaning of Section 412 of the Code or Section
         302 of ERISA. Neither SBC nor any of its Subsidiaries has provided, or
         is required to provide, security to any SBC Pension Plans or to any of
         its ERISA Affiliate Plans pursuant to Section 401(a)(29) of the Code.

                           (v) Under each of the SBC Pension Plans which is a
         single-employer plan and each of SBC's ERISA Affiliate Plans, as of the
         last day of the most recent plan year ended prior to the date hereof,
         the actuarially determined present value of all "benefit liabilities,"
         within the meaning of Section 4001(a)(16) of ERISA (as determined on
         the basis of the actuarial assumptions contained in such SBC Pension
         Plan's or SBC ERISA Affiliate Plan's most recent actuarial valuation),
         did not exceed the then current value of the assets of such SBC Pension
         Plan or SBC ERISA Affiliate Plan, and there has been no material change
         in the financial condition of such SBC Pension Plan or SBC ERISA
         Affiliate Plan since the last day of the most recent plan year as such
         would affect any of the SBC Companies.

                           (vi) Except as set forth on Schedule 3.1(i)(vi) to
         the SBC Disclosure Letter, there are no material obligations to the SBC
         Employees for retiree health and life benefits under any of the SBC
         Compensation and Benefit Plans or as required by applicable law.

                           (vii) The consummation of the transactions
         contemplated by this Agreement (whether alone or in connection with any
         other event) will not (x) entitle any SBC Employee to severance pay,
         directly or indirectly, upon termination of employment, (y) accelerate
         the time of payment or vesting or trigger any payment of compensation
         or benefits under, increase the amount payable or trigger any other
         material obligation pursuant to, any of the SBC Compensation and
         Benefit Plans or (z) result in any breach or violation of, or a default
         under, any of the SBC Compensation and Benefit Plans, but excluding any

                                      -32-
<PAGE>   38
         exceptions to (x), (y) and (z) which are not, individually or in the
         aggregate, material.

                           (viii) Since December 31, 1999, except as
         contemplated hereby, there has not been any increase in the
         compensation payable or that could become payable by the SBC Companies
         or any of their Subsidiaries to any SBC Employee or any amendment of
         any of the SBC Compensation and Benefit Plans other than increases or
         amendments in the ordinary course of business consistent with past
         practice.

                  (j) Compliance with Laws. The SBC Business and businesses of
each of the SBC Companies and their Subsidiaries have not been, and are not
being, conducted in violation of any federal, state, local or foreign law,
statute, ordinance, regulation, judgment, order, decree, injunction, arbitration
award, franchise, license, authorization, opinion, agency requirement or permit
of any Governmental Entity or common law (collectively, "Laws"), except for
violations or possible violations that have not had and would not, individually
or in the aggregate, be reasonably likely to have a Material Adverse Effect on
the SBC Companies or prevent or materially impair SBC's ability to consummate
the transactions contemplated by this Agreement. No investigation or review by
any Governmental Entity with respect to the SBC Companies or any of their
Subsidiaries is pending or, to the Knowledge of SBC, threatened, nor has any
Governmental Entity indicated an intention to conduct the same, except for those
the outcome of which have not had and would not, individually or in the
aggregate, be reasonably likely to have a Material Adverse Effect on the SBC
Companies or prevent or materially impair SBC's ability to consummate the
transactions contemplated by this Agreement. Each of the SBC Companies and their
Subsidiaries has all permits, licenses, franchises, variances, exemptions,
orders and other governmental authorizations, consents and approvals
(collectively, "Permits"), necessary to conduct their businesses as presently
conducted, except for those Permits the absence of which has not had and would
not, individually or in the aggregate, be reasonably likely to have a Material
Adverse Effect on the SBC Companies or prevent or materially impair SBC's
ability to consummate the transactions contemplated by this Agreement.

                  (k) Environmental Matters. Except for such matters that,
individually or in the aggregate, have not had and would not be reasonably
likely to have a Material Adverse Effect on the SBC Companies: (i) each of the
SBC Companies and their Subsidiaries has complied with all applicable
Environmental Laws; (ii) the properties currently owned or operated by the SBC
Companies or any of their Subsidiaries (including soils, groundwater, surface
water, buildings or other structures) are not contaminated with any Hazardous
Substances; (iii) the properties formerly owned or operated by the SBC

                                      -33-
<PAGE>   39
Companies or any of their Subsidiaries were not contaminated with Hazardous
Substances during the period of ownership or operation by the SBC Companies or
any of their Subsidiaries; (iv) neither the SBC Companies nor any of their
Subsidiaries is subject to liability for any Hazardous Substance disposal or
contamination on any third party property; (v) neither the SBC Companies nor any
of their Subsidiaries has received any notice, demand, letter, claim or request
for information alleging that the SBC Companies or any of their Subsidiaries may
be in violation of or liable under any Environmental Law.

                  (l) Labor Matters. None of the SBC Companies nor any of their
Subsidiaries is the subject of any proceeding relating to any SBC Employee
before the National Labor Relations Board asserting the commission of an unfair
labor practice or is seeking to compel any of them to bargain with any labor
union or labor organization nor is there pending or, to the Knowledge of SBC,
threatened, nor has there been since January 1, 1995, any labor strike, dispute,
walkout, work stoppage, slow-down or lockout relating to any SBC Employee,
except in each case as has not had and would not, individually or in the
aggregate, be reasonably likely to have a Material Adverse Effect on the SBC
Companies. The collective bargaining agreements set forth on Schedule 3.1(l) of
the SBC Disclosure Letter are the only collective bargaining agreements relating
to any SBC Employee.

                  (m) Taxes. (i) SBC, the SBC Companies and each of their
Subsidiaries have prepared in good faith and duly and timely filed (taking into
account any extension of time within which to file) all material Tax Returns
required to be filed by any of them with respect to the SBC Companies or any of
their Subsidiaries and all such filed tax returns are complete and accurate in
all material respects; (ii) the SBC Companies and each of their Subsidiaries
have paid all Taxes that are shown as due on such filed Tax Returns or that the
SBC Companies or any of their Subsidiaries are obligated to withhold from
amounts owing to any employee, creditor or third party, except with respect to
matters contested in good faith or for such amounts that, individually or in the
aggregate, have not had and would not be reasonably likely to have a Material
Adverse Effect on the SBC Companies; (iii) as of the date hereof, there are not
pending or, to the Knowledge of SBC, threatened, in writing, any audits,
examinations, investigations or other proceedings in respect of Taxes or Tax
matters with respect to the SBC Companies; and (iv) there are not, to the
Knowledge of SBC, any unresolved questions or claims concerning the SBC
Companies' or any of their Subsidiaries' Tax liability that have had or would be
reasonably likely to have a Material Adverse Effect on the SBC Companies. No
material payments to be made to any of the officers or employees of the SBC
Companies or any of their Subsidiaries will as a result of consummation of the
transactions contemplated hereby be subject to the deduction limitations under
Section 280G of the Code.

                  (n) Regulatory Matters. The SBC Companies and their
Subsidiaries hold all licenses, franchises, certificates, consents, Permits,
qualifications and

                                      -34-
<PAGE>   40
authorizations (including, without limitation, licenses granted by the FCC ("FCC
Licenses"), and licenses, authorizations and certificates of public convenience
and necessity from applicable state and local authorities) from all Governmental
Entities required under Utilities Laws ("Licenses") necessary for the lawful
conduct of the SBC Business, other than Licenses the lack of which, individually
or in the aggregate, have not had and would not be reasonably likely to have a
Material Adverse Effect on the SBC Companies. Schedule 3.1(n) of the SBC
Disclosure Letter sets forth each License obtained by SBC or any of its
Subsidiaries and which is, or in the absence of a violation thereof, would be in
full force and effect with respect to the SBC Business (the "SBC Companies'
Licenses"). To the Knowledge of SBC, no event has occurred or fact exists with
respect to the SBC Companies' Licenses (other than the requirement to file in
the future applications for renewal and obtain renewals in the ordinary course)
which permits, or after notice or lapse of time or both would permit,
revocation, non-renewal or termination of any of such licenses or would result
in any other impairment of the rights of the holder of any of such licenses or
which would be reasonably likely to limit the operation of the SBC Companies'
and their Subsidiaries' businesses as they are currently conducted, except for
revocations, limitations, non-renewals or other terminations which, individually
or in the aggregate, have not had and would not be reasonably likely to have a
Material Adverse Effect on the SBC Companies. The SBC Companies and their
Subsidiaries have performed their respective obligations under the SBC
Companies' Licenses with such exceptions which, individually or in the
aggregate, have not had and would not be reasonably likely to have a Material
Adverse Effect on the SBC Companies. The FCC actions granting the SBC Companies'
Licenses, together with all underlying construction permits, have not been
reversed, stayed, enjoined, annulled or suspended, and there is not pending or,
to the Knowledge of SBC, threatened, any application, petition, objection or
other pleading with the FCC or other Governmental Entity which challenges or
questions the validity of or any rights of the holder under any of the SBC
Companies' Licenses, except for such reversals, stays, injunctions, annulments,
suspensions, applications, petitions, objections or other pleadings, which have
not had and would not, individually or in the aggregate, be reasonably likely to
have a Material Adverse Effect on the SBC Companies.

                  (o) Contracts. Schedule 3.1(o) of the SBC Disclosure Letter
lists the following Contracts to which any of the SBC Companies or any of their
Subsidiaries is a party:

                           (A) any agreement which materially restricts or
         materially limits their ability or the ability of any of their
         respective Affiliates to freely conduct the SBC Business or any other
         business or otherwise operate in any geographic market;

<PAGE>   41

         be deemed to include all leases of real property, with an annual rental

         relating to cellular towers;

                           (E) all partnership, shareholder or joint venture
         agreements or other agreements relating to the management or Control of
         any such partnership, joint venture or non-wholly owned Subsidiary;

                           (ii) Each Contract listed on Schedule 3.1(o) to the
         SBC Disclosure Letter is valid, binding, enforceable, and in full force
         and effect, the SBC Companies or the applicable Subsidiary are not in
         breach or default under any such Contract and no event has occurred
         which, with notice or lapse of time or both, would constitute such a
         breach or default, or permit termination, modification, or
         acceleration, under such Contract, except where the failure to be so
         valid, binding, enforceable or in full force and effect or such breach
         or default, termination, modification or acceleration has not had and
         would not be, either individually or in the aggregate, reasonably
         likely to have a Material Adverse Effect on the SBC Companies.

                  (p) Property and Leases. Schedule 3.1(p) to the SBC Disclosure
Letter contains a list of all real property owned by the SBC Companies or any of
their respective Subsidiaries or otherwise used primarily in the SBC Business

                  (r) Ownership of Assets. Substantially all of the assets,
properties, businesses, licenses and other assets, owned or leased by SBC and
its Subsidiaries and forming a part of the SBC Business are owned or leased by
the SBC Companies and their respective Subsidiaries.

                  (s) Sufficiency of Assets. The assets and properties owned or
leased by the SBC Companies or their respective Subsidiaries, together with all
Contracts to which the SBC Companies or their respective Subsidiaries are a
party, constitute the assets, properties and Contract rights reasonably
necessary to conduct the SBC Business in accordance with past practice.

                  (t) Other Business. Other than with respect to the Excluded
SBC Business, none of the SBC Companies, their respective Subsidiaries or the
SBC Additional Subsidiaries conducts or engages in any business material to the
SBC Companies and their Subsidiaries taken as a whole other than the SBC
Business or owns or leases any assets material to the SBC Companies and their
Subsidiaries taken as a whole that are not used or intended for the use in the
SBC Business, other than obsolete assets.

                  (u) Intellectual Property. Subject to Section 4.16
(Intercompany Obligations), the SBC Companies and their Subsidiaries each own,
or possess adequate licenses or other valid rights to use, all trademarks,
trademark rights, trade names, trade name rights, patents, patent rights,
industrial models, inventions, copyrights, service marks, trade secrets,
applications for trademarks and for service marks, know-how and other
proprietary rights and information, including rights to software (collectively,
"Intellectual Property Rights") used or held for use in connection with the SBC
Business except where the failure to have such ownership, possession or rights
would not, individually or in the aggregate, be reasonably likely to have a
Material Adverse Effect on the SBC Companies. To the Knowledge of SBC, the SBC
Companies and their Subsidiaries are not the subject of any threatened or
pending lawsuits alleging the violation or infringement of any Intellectual
Property Rights of any third party that, individually or in the aggregate, would
be reasonably likely to have a Material Adverse Effect on the SBC Companies. To
the Knowledge of SBC, there are no material infringements of any Intellectual
Property Right owned by any of the SBC Companies or their Subsidiaries. None of
the SBC Companies or their Subsidiaries is in material breach of any agreements
pursuant to which any of them has a license to use Intellectual Property Rights,
and consummation of the transactions contemplated hereby will not constitute
such a material breach or otherwise reduce or impair, in any material respect,
the rights of any of them under such license agreements other than any breach
which would not, individually or in the aggregate, be reasonably likely to have
a Material Adverse Effect on the SBC Companies. No claims are pending or, to the
Knowledge of SBC, threatened by any Person with respect to the ownership,
validity or enforceability of

                                      -37-
<PAGE>   43
any Intellectual Property Rights owned by any of the SBC Companies or their
Subsidiaries, or challenging or questioning the right of the SBC Companies or
their Subsidiaries to use any Intellectual Property Rights owned by them, except
claims that would not, individually or in the aggregate, be reasonably likely to
have a Material Adverse Effect.

                  (v) No Other Representations and Warranties. Except for
representations and warranties contained in this Agreement, none of SBC, the SBC
Companies or their Affiliates, or any other Person makes any express or implied
representation or warranty on behalf of SBC with respect to the subject matter
of this Agreement.

the corresponding sections or subsections of the BellSouth Disclosure Letter,

own and operate its properties and assets and to carry on its business as
presently conducted and is qualified to do business and is in good standing as a
foreign corporation in each jurisdiction where the ownership or operation of its
properties or conduct of its business requires such qualification, except where

BellSouth Companies. It has made available to SBC a complete and correct copy of
its, its Subsidiaries that own of record BellSouth Shares, the BellSouth
Companies' and the BellSouth Companies' Subsidiaries' certificates of
incorporation, articles of incorporation or other comparable governing

         Consents"), no notices, reports or other filings are required to be
         made by it with, nor are any consents, registrations, approvals,
         permits or authorizations required to be obtained by it or its
         Subsidiaries from, any Governmental Entity, in connection with the
         execution and delivery of this Agreement by it and the consummation by
         it of the BellSouth Contribution or the BellSouth Additional Closings
         hereby, except those that the failure to make or obtain would not,
         individually or in the aggregate, be reasonably likely to have a
         Material Adverse Effect on the BellSouth Companies or prevent,
         materially delay or materially impair its ability to consummate the
         transactions contemplated by this Agreement.

                           (ii) The execution, delivery and performance of this
         Agreement by it do not, and the consummation by it of the transactions
         contemplated hereby will not, constitute or result in (A) a breach or
         violation of, or a default under, its certificate of incorporation,

         organizational documents, including partnership agreements and limited
         liability company agreements, of any of the BellSouth Companies, (B) a
         breach or violation of, or any default under the certificate of
         incorporation or other organizational documents, including partnership
         agreements and limited liability company agreements, of any
         Subsidiaries of the BellSouth Companies, (C) a breach or violation of,

         of time or both) pursuant to any Contract binding upon it or any of its

         non-governmental permit or license to which it or any of its
         Subsidiaries is subject or (D) any change in the rights or obligations
         of any party under any of its or its Subsidiaries' Contracts, except,
         in the case of clause (B), (C) or (D) above, for any breach, violation,
         default, acceleration, creation or change that, individually or in the
         aggregate, would not be reasonably likely to have a Material Adverse
         Effect on the BellSouth Companies or prevent, materially delay or
         materially impair its ability to consummate the transactions
         contemplated by this Agreement.

                  (c) Capitalization of the BellSouth Companies. The issued and
outstanding BellSouth Shares have been duly authorized and validly issued, are
fully paid and nonassessable and are owned by BellSouth or direct or indirect

         similar equity interests of each Subsidiary of a BellSouth Company that
         are owned by such BellSouth Company or a Subsidiary of a BellSouth
         Company are owned by a BellSouth Company or the applicable Subsidiary
         free and clear of all Encumbrances, and all such equity interests are
         duly authorized, validly issued and fully paid.

                           (ii) As of the date hereof, none of the BellSouth
         Companies or any of their Subsidiaries has any obligation to sell,

contemplated by this Agreement and except with respect to the Excluded BellSouth

their respective businesses only in the ordinary and usual course of such
businesses; (ii) there has not been any change in the financial condition,
properties, business or results of operations of the BellSouth Companies and
their Subsidiaries, except those changes that have not had and would not,
individually or in the aggregate, be reasonably likely to have a Material
Adverse Effect on the BellSouth Companies; (iii) there has not been any damage,
destruction or other casualty loss with respect to any asset or property owned,
leased or otherwise used by the BellSouth Companies and their Subsidiaries,
whether or not covered by insurance, which damage, destruction or loss is
reasonably likely, individually or in the aggregate, to have a Material Adverse
Effect on the BellSouth Companies; (iv) there has not been any sale, transfer,
conveyance, lease, creation of an Encumbrance or other disposition of assets of
the BellSouth Companies and their Subsidiaries outside of the ordinary course of

                  (h) Litigation and Liabilities. There are no (i) civil,
criminal or administrative actions, suits, claims, hearings, investigations or
proceedings pending or, to the Knowledge of BellSouth, threatened against the
BellSouth Companies or any of their Affiliates or otherwise in connection with
the BellSouth Business or (ii) obligations or liabilities, whether or not
accrued, contingent or otherwise that are required to be disclosed under GAAP,
or any other facts or circumstances, in either such case, of which BellSouth has
Knowledge that are reasonably likely to result in any claims against or
obligations or liabilities of it or any of its Affiliates, except for those that
have not had and are not, individually or in the aggregate, reasonably likely to
have a Material Adverse Effect on the BellSouth Companies or prevent or
materially impair or delay BellSouth's ability to consummate the transactions
contemplated by this Agreement.

                  (i)      BellSouth Employee Benefits.

         pension, retirement, profit-sharing, thrift, savings, employee stock
         ownership, stock bonus,

                                      -41-
<PAGE>   47
         stock purchase, restricted stock, stock option, employment,
         termination, severance, compensation, medical, health or other plan,
         agreement, policy or arrangement (the "BellSouth Compensation and
         Benefit Plans") that covers employees, directors, former employees or
         former directors of the BellSouth Companies or their Subsidiaries and
         any other employee of BellSouth or an employee of BellSouth Companies
         whose duties are primarily related (or, for persons who no longer
         perform such services, were related) to the BellSouth Business (the
         "BellSouth Employees") and any trust agreements or insurance contracts
         forming a part of the BellSouth Compensation and Benefit Plans is set
         forth in Schedule 3.2(i)(i) of the BellSouth Disclosure Letter.

                           (ii) All of the BellSouth Compensation and Benefit
         Plans are in compliance with the terms and with all applicable Law,
         including the Code and ERISA, except for failures to comply which are
         not, individually or in the aggregate, reasonably likely to have a
         Material Adverse Effect on the BellSouth Companies. Each of the
         BellSouth Compensation and Benefit Plans that is an "employee pension
         benefit plan" within the meaning of Section 3(2) of ERISA (a "BellSouth
         Pension Plan" and collectively, the "BellSouth Pension Plans") and that
         is intended to be qualified under Section 401(a) of the Code has
         received a favorable determination letter from the IRS, and BellSouth
         does not have Knowledge of any circumstances likely to result in
         revocation of any such favorable determination letter. There is no
         pending or, to the Knowledge of BellSouth, threatened claim, audit,
         investigation, litigation or other proceeding relating to the BellSouth
         Compensation and Benefit Plans, except for proceedings which are not,
         individually or in the aggregate, reasonably likely to have a Material
         Adverse Effect on the BellSouth Companies. Neither BellSouth nor any
         Subsidiary of BellSouth has engaged in a transaction with respect to
         any of the BellSouth Compensation and Benefit Plans that, assuming the
         taxable period of such transaction expired as of the date hereof, would
         subject the BellSouth Companies or any of their Subsidiaries to a
         material tax or penalty imposed by either Section 4975 of the Code or
         Section 502 of ERISA.

                           (iii) As of the date hereof, no liability under
         Subtitle C or D of Title IV of ERISA (other than the payment of
         prospective premium amounts to the Pension Benefit Guaranty Corporation
         in the normal course) has been or is expected to be incurred by the
         BellSouth Companies or any of their Subsidiaries with respect to any
         ongoing, frozen or terminated "single-employer plan", within the
         meaning of Section 4001(a)(15) of ERISA, currently or formerly
         maintained by any of them, or any of its ERISA Affiliate Plans. The
         BellSouth Companies, their Subsidiaries and their ERISA Affiliates have
         not contributed, or been obligated to contribute, to a multiemployer
         plan under Subtitle E of Title IV of ERISA at any time since September
         26, 1980. No notice of a "reportable event",

                                      -42-
<PAGE>   48
         within the meaning of Section 4043 of ERISA for which the 30-day
         reporting requirement has not been waived, has been required to be
         filed for any of the BellSouth's Pension Plans or any of its ERISA
         Affiliate Plans within the 12-month period ending on the date hereof or
         will be required to be filed in connection with the transactions
         contemplated by this Agreement.

                           (iv) None of the BellSouth Pension Plans nor any of
         BellSouth's ERISA Affiliate Plans has an "accumulated funding
         deficiency" (whether or not waived) within the meaning of Section 412
         of the Code or Section 302 of ERISA. Neither BellSouth nor any of its
         Subsidiaries has provided, or is required to provide, security to any
         BellSouth Pension Plans or to any of its ERISA Affiliate Plans pursuant
         to Section 401(a)(29) of the Code.

                           (v) Under each of the BellSouth Pension Plans which
         is a single-employer plan and each of BellSouth's ERISA Affiliate
         Plans, as of the last day of the most recent plan year ended prior to
         the date hereof, the actuarially determined present value of all
         "benefit liabilities," within the meaning of Section 4001(a)(16) of
         ERISA (as determined on the basis of the actuarial assumptions
         contained in such BellSouth Pension Plan's or BellSouth ERISA Affiliate
         Plan's most recent actuarial valuation), did not exceed the then
         current value of the assets of such BellSouth Pension Plan or BellSouth
         ERISA Affiliate Plan, and there has been no material change in the
         financial condition of such BellSouth Pension Plan or BellSouth ERISA
         Affiliate Plan since the last day of the most recent plan year as such
         would affect any of the BellSouth Companies.

                           (vi) Except as set forth on Schedule 3.2(i)(vi) to
         the BellSouth Disclosure Letter, there are no material obligations to
         the BellSouth Employees for retiree health and life benefits under any
         of the BellSouth Compensation and Benefit Plans or as required by
         applicable law.

                           (vii) The consummation of the transactions
         contemplated by this Agreement (whether alone or in connection with any
         other event) will not (x) entitle any BellSouth Employee to severance
         pay, directly or indirectly, upon termination of employment, (y)
         accelerate the time of payment or vesting or trigger any payment of
         compensation or benefits under, increase the amount payable or trigger
         any other material obligation pursuant to, any of the BellSouth
         Compensation and Benefit Plans or (z) result in any breach or violation
         of, or a default under, any of the BellSouth Compensation and Benefit
         Plans, but excluding any exceptions to (x), (y) and (z) which are not,
         individually or in the aggregate, material.

                                      -43-
<PAGE>   49
                           (viii) Since November 30, 1999, except as
         contemplated hereby, there has not been any increase in the
         compensation payable or that could become payable by the BellSouth
         Companies or any of their Subsidiaries to any BellSouth Employee or any
         amendment of any of the BellSouth Compensation and Benefit Plans other
         than increases or amendments in the ordinary course of business
         consistent with past practice.

                  (j) Compliance with Laws. The BellSouth Business and
businesses of each of the BellSouth Companies and their Subsidiaries have not
been, and are not being, conducted in violation of any Law, except for
violations or possible violations that have not had and would not, individually
or in the aggregate, be reasonably likely to have a Material Adverse Effect on
the BellSouth Companies or prevent or materially impair BellSouth's ability to
consummate the transactions contemplated by this Agreement. No investigation or
review by any Governmental Entity with respect to the BellSouth Companies or any
of their Subsidiaries is pending or, to the Knowledge of BellSouth, threatened,
nor has any Governmental Entity indicated an intention to conduct the same,
except for those the outcome of which have not had and would not, individually
or in the aggregate, be reasonably likely to have a Material Adverse Effect on
the BellSouth Companies or prevent or materially impair BellSouth's ability to
consummate the transactions contemplated by this Agreement. Each of the
BellSouth Companies and their Subsidiaries has all Permits, necessary to conduct
their businesses as presently conducted, except for those Permits the absence of
which has not had and would not, individually or in the aggregate, be reasonably
likely to have a Material Adverse Effect on the BellSouth Companies or prevent
or materially delay BellSouth's ability to consummate the transactions
contemplated by this Agreement.

                  (k) Environmental Matters. Except for such matters that,
individually or in the aggregate, have not had and would not be reasonably
likely to have a Material Adverse Effect on the BellSouth Companies, taken as a
whole: (i) each of the BellSouth Companies and their Subsidiaries has complied
with all applicable Environmental Laws; (ii) the properties currently owned or
operated by the BellSouth Companies or any of their Subsidiaries (including
soils, groundwater, surface water, buildings or other structures) are not
contaminated with any Hazardous Substances; (iii) the properties formerly owned
or operated by the BellSouth Companies or any of their respective Subsidiaries
were not contaminated with Hazardous Substances during the period of ownership
or operation by the BellSouth Companies or any of their Subsidiaries; (iv)
neither the BellSouth Companies nor any of their Subsidiaries is subject to
liability for any Hazardous Substance disposal or contamination on any third
party property; (v) neither the BellSouth Companies nor any of their
Subsidiaries has received any notice, demand, letter, claim or request for
information alleging that the BellSouth Companies nor any of their respective
Subsidiaries may be in violation of or liable under any Environmental Law.

                  (l) Labor Matters. None of the BellSouth Companies nor any of
their Subsidiaries is the subject of any proceeding relating to any BellSouth
Employee before the National Labor Relations Board asserting the commission of
an unfair labor practice or is seeking to compel any of them to bargain with any
labor union or labor organization nor is there pending or, to the Knowledge of
BellSouth, threatened, nor has there been since January 1, 1995, any labor
strike, dispute, walkout, work stoppage, slow-down or lockout relating to any
BellSouth Employee, except in each case as has not and would not, individually
or in the aggregate, be reasonably likely to have a Material Adverse Effect on
the BellSouth Companies. The collective bargaining agreements set forth on
Schedule 3.2(l) to the BellSouth Disclosure Letter are the only collective
bargaining agreements relating to any BellSouth Employee.

                  (m) Taxes. (i) BellSouth, the BellSouth Companies and each of
their Subsidiaries have prepared in good faith and duly and timely filed (taking
into account any extension of time within which to file) all material Tax
Returns required to be filed by any of them with respect to the BellSouth
Companies or any of their Subsidiaries and all such filed tax returns are
complete and accurate in all material respects; (ii) the BellSouth Companies and
each of their Subsidiaries have paid all Taxes that are shown as due on such
filed Tax Returns or that the BellSouth Companies or any of their Subsidiaries
are obligated to withhold from amounts owing to any employee, creditor or third
party, except with respect to matters contested in good faith or for such
amounts that, individually or in the aggregate have not had and would not be
reasonably likely to have a Material Adverse Effect on the BellSouth Companies;
(iii) as of the date hereof, there are not pending or, to the Knowledge of
BellSouth, threatened, in writing, any audits, examinations, investigations or
other proceedings in respect of Taxes or Tax matters with respect to the
BellSouth Companies; and (iv) there are not, to the Knowledge of BellSouth, any
unresolved questions or claims concerning the BellSouth Companies' or any of
their Subsidiaries' Tax liability that have had or would be reasonably likely to
have a Material Adverse Effect on the BellSouth Companies. No material payments
to be made to any of the officers or employees of the BellSouth Companies or any
of their Subsidiaries will as a result of consummation of the transactions
contemplated hereby be subject to the deduction limitations under Section 280G
of the Code.

                  (n) Regulatory Matters. The BellSouth Companies and their
Subsidiaries hold all Licenses necessary for the lawful conduct of the BellSouth
Business other than Licenses the lack of which, individually or in the
aggregate, have not had and would not be reasonably likely to have a Material
Adverse Effect on the BellSouth Companies. Schedule 3.2(n) of the BellSouth
Disclosure Letter sets forth each License obtained by BellSouth or any of its
Subsidiaries and which is, or in the absence of a violation thereof, would be in
full force and effect with respect to the BellSouth Business (the "BellSouth
Companies' Licenses"). To the Knowledge of BellSouth, no event has

                                      -45-
<PAGE>   51
occurred or fact exists with respect to the BellSouth Companies Licenses (other
than the requirement to file in the future applications for renewal and obtain
renewals in the ordinary course) which permits, or after notice or lapse of time
or both would permit, revocation, non-renewal or termination of any of such
licenses or would result in any other impairment of the rights of the holder of
any of such licenses or which would be reasonably likely to limit the operation
of the BellSouth Companies' and their Subsidiaries' businesses as they are
currently conducted, except for revocations, limitations, non-renewals or other
terminations which, individually or in the aggregate, have not had and would not
be reasonably likely to have a Material Adverse Effect on the BellSouth
Companies. The BellSouth Companies and their Subsidiaries have performed their
respective obligations under such BellSouth Companies' Licenses with such
exceptions which, individually or in the aggregate, have not had and would not
be reasonably likely to have a Material Adverse Effect on the BellSouth
Companies. The FCC actions granting the BellSouth Companies' Licenses, together
with all underlying construction permits, have not been reversed, stayed,
enjoined, annulled or suspended, and there is not pending or, to the Knowledge
of BellSouth, threatened, any application, petition, objection or other pleading
with the FCC or other Governmental Entity which challenges or questions the
validity of or any rights of the holder under any of the BellSouth Companies'
Licenses, except for such reversals, stays, injunctions, annulments,
suspensions, applications, petitions, objections or other pleadings, which have
not had and would not, individually or in the aggregate, be reasonably likely to
have a Material Adverse Effect on the BellSouth Companies.

                  (o) Contracts. (i) Schedule 3.2(o) of the BellSouth Disclosure
Letter lists the following Contracts to which any of the BellSouth Companies or
one of their Subsidiaries is a party:

                           (A) any agreement which materially restricts or
         materially limits their ability or the ability of any of their
         respective Affiliates to freely conduct the BellSouth Business or any
         other business or otherwise operate in any geographic market;

                           (B) any collective bargaining agreement and any
         written employment agreement;

                           (C) all agreements with respect to outstanding
         indebtedness for money borrowed in excess of $50,000,000 or any
         guaranty thereof;

                           (D) all material leases of real property, which shall
         be deemed to include all leases of real property, with an annual rental
         payment in excess of $50,000, and all arrangements relating to a
         sublease of space on the cellular towers;

                                      -46-
<PAGE>   52
                           (E) all partnership, shareholder or joint venture
         agreements or other agreements relating to the management or Control of
         any such partnership, joint venture or non-wholly owned Subsidiary;

                           (F) all interconnection agreements; and

                           (G) any roaming agreements not terminable at the
         option of either party thereto on 90 days or less notice.

                           (ii) Each Contract listed on Schedule 3.2(o) to the
         BellSouth Disclosure Letter is valid, binding, enforceable, and in full
         force and effect, the BellSouth Companies or the applicable Subsidiary
         are not in breach or default under any such Contract and no event has
         occurred which, with notice or lapse of time or both, would constitute
         such a breach or default, or permit termination, modification, or
         acceleration, under such Contract, except where the failure to be so
         valid, binding, enforceable or in full force and effect or such breach
         or default, termination, modification or acceleration would not be,
         either individually or in the aggregate, reasonably likely to have a
         Material Adverse Effect on the BellSouth Companies.

                  (p) Property and Leases. Schedule 3.2(p) to the BellSouth
Disclosure Letter contains a list of all real property owned by the BellSouth
Companies or any of their respective Subsidiaries or otherwise used primarily in
the BellSouth Business and real property leased pursuant to lease agreements set
forth on Schedule 3.2(o). The BellSouth Companies and their Subsidiaries have
marketable title to all material owned real property set forth on Schedule
3.2(p) and valid leasehold title to all material leased real property set forth
on Schedule 3.2(o), in each case free and clear of all Encumbrances, other than
Permitted Encumbrances.

                  (q) Brokers and Finders. Neither the BellSouth Companies nor
any of their respective officers, directors or employees has employed any broker
or finder or incurred any liability for any brokerage fees, commissions or
finders' fees in connection with the BellSouth transactions contemplated in this
Agreement.

                  (r) Ownership of Assets. Substantially all of the assets,
properties, businesses, licenses and other assets, owned or leased by BellSouth
and its Subsidiaries and forming a part of the BellSouth Business are owned or
leased by the BellSouth Companies and their respective Subsidiaries.

                  (s) Sufficiency of Assets. The assets and properties owned or
leased by the BellSouth Companies or their respective Subsidiaries, together
with all Contracts to which the BellSouth Companies or their respective
Subsidiaries are a party, constitute

                                      -47-
<PAGE>   53
the assets, properties and Contract rights reasonably necessary to conduct the
BellSouth Business in accordance with past practice.

                  (t) Other Business. Other than with respect to the Excluded
BellSouth Business, none of the BellSouth Companies, their respective
Subsidiaries or the BellSouth Additional Subsidiary conducts or engages in any
business material to the BellSouth Companies and their Subsidiaries taken as a
whole other than the BellSouth Business or owns or leases any assets material to
the BellSouth Companies and their Subsidiaries taken as a whole that are not
used or intended for the use in the BellSouth Business, other than obsolete
assets.

                  (u) Intellectual Property. Subject to Section 4.16
(Intercompany Obligations), the BellSouth Companies and their Subsidiaries each
own, or possess adequate licenses or other valid rights to use, all Intellectual
Property Rights used or held for use in connection with the BellSouth Business
except where the failure to have such ownership or rights would not,
individually or in the aggregate be reasonably likely to have a Material Adverse
Effect on the BellSouth Companies. To the Knowledge of BellSouth, the BellSouth
Companies and their Subsidiaries are not the subject of any threatened or
pending lawsuits alleging the violation or infringement of any Intellectual
Property Rights of any third party that, individually or in the aggregate, would
be reasonably likely to have a Material Adverse Effect on the BellSouth
Companies. To the Knowledge of BellSouth, there are no material infringements of
any Intellectual Property Right owned by any of the BellSouth Companies or their
Subsidiaries. None of the BellSouth Companies or their Subsidiaries is in
material breach of any agreements pursuant to which any of them has a license to
use Intellectual Property Rights, and consummation of the transactions
contemplated hereby will not constitute such a material breach or otherwise
reduce or impair, in any material respect, the rights of any of them under such
license agreements, other than any breach which would not, individually or in
the aggregate, be reasonably likely to have a Material Adverse Effect on the
BellSouth Companies. No claims are pending or, to the Knowledge of BellSouth,
threatened by any Person with respect to the ownership, validity or
enforceability of any Intellectual Property Rights owned by any of the BellSouth
Companies or their Subsidiaries, or challenging or questioning the right of the
BellSouth Companies or their Subsidiaries to use any Intellectual Property
Rights owned by them, except claims that would not, individually or in the
aggregate, be reasonably likely to have a Material Adverse Effect.

                  (v) No Other Representations and Warranties. Except for
representations and warranties contained in this Agreement, none of BellSouth,
the BellSouth Companies or their Affiliates, or any other Person makes any
express or implied representation or warranty on behalf of BellSouth with
respect to the subject matter of this Agreement.

         4.1      Access and Information.

                  (a) Prior to the Closing (and with respect to each of the
Additional Subsidiaries, prior to the earlier to occur of the time such
Additional Subsidiary is conveyed to Newco and December 31, 2009), SBC and
BellSouth shall each permit the other and the other's representatives to have
reasonable access to its Books and Records, officers and Subsidiaries, in each
case (i) during regular business hours and upon reasonable advance notice to the
other, (ii) to the extent that such access does not unreasonably interfere with
the business of the SBC Companies or their Subsidiaries or the BellSouth
Companies or their Subsidiaries, as the case may be and (iii) to the extent
relating to the SBC Companies, the BellSouth Companies and their respective
Subsidiaries; provided, that any such representatives shall comply with the
confidentiality obligations contained herein and in the Confidentiality
Agreement and; provided, further that the foregoing shall not (i) require SBC or
BellSouth to permit any inspection, or to disclose any information, that in its
reasonable judgment would result in the disclosure of any trade secrets of third
parties or trade secrets of SBC or BellSouth unrelated to the SBC Companies and
their Subsidiaries or the BellSouth Companies and their Subsidiaries, as the
case may be, or violate any of SBC's, BellSouth's, the SBC Companies', the
BellSouth Companies' or any of their respective Subsidiaries' legal obligations
or obligations with respect to confidentiality if SBC or BellSouth, as the case
may be, shall have used reasonable best efforts to obtain the consent of such
third party to such inspection or disclosure, or (ii) require any disclosure by
SBC, BellSouth, the SBC Companies, the BellSouth Companies or any of their
Subsidiaries that would be reasonably likely to, as a result of such disclosure,
have the effect of causing the waiver of any attorney-client privilege;
provided, that SBC or BellSouth, as the case may be, shall have used its
commercially reasonable efforts to effect disclosure without the waiver of
attorney-client privilege.

                  (b) In the event of the termination of this Agreement, SBC and
BellSouth, each at its own expense, shall promptly deliver (without retaining
any copies thereof) to BellSouth or SBC, as the case may be, or confirm to the
other in writing that it has destroyed, all information furnished to it or its
representatives by the other or any of the other's Subsidiaries or any of their
respective agents, employees or representatives as a result hereof or in
connection herewith, whether so obtained before or after the execution hereof,
and all analyses, compilations, forecasts, studies or other documents prepared
by it or its representatives which contain or reflect any such information. SBC
and BellSouth shall, and shall cause their respective employees, officers,
directors and Subsidiaries and the employees, officers and directors of their
Subsidiaries to, subject to any exceptions set forth in the Confidentiality
Agreement, cause any information so

information in its business or in any other manner or for any other purpose
except as contemplated hereby.

                  (c) In addition to the confidentiality arrangements contained
herein, all information provided or obtained in connection with the transactions
contemplated by this Agreement (including pursuant to clause (a) above) shall be
held in accordance with and subject to the terms of the Confidentiality
Agreement, dated February 18, 2000, between SBC and BellSouth (the
"Confidentiality Agreement"). In the event of a conflict or inconsistency
between the terms of this Agreement and the Confidentiality Agreement, the terms
of this Agreement shall govern.

         4.4 Employee Benefit Plan/Employees. (a) At least one week prior to the
Closing Date, SBC and BellSouth shall each form a new Subsidiary (such
Subsidiary of SBC being the "SBC Leasing Company" and such Subsidiary of
BellSouth being the "BellSouth Leasing Company," and, together, the "Leasing
Companies"); provided that, instead of such formation, either of the Parties may
designate an existing Subsidiary with no assets or liabilities as its Leasing
Company. SBC and BellSouth shall as soon as reasonably practicable, but in no
event later than 90 days from the date hereof, agree on the terms and conditions
of the Leasing Agreements (which shall be substantially similar) to be entered
into by SBC Leasing Company and BellSouth Leasing Company, respectively, with
Newco, which shall be consistent with the terms and conditions of this Section
4.4. SBC and BellSouth shall take and shall cause to be taken all action
necessary to effectuate the provisions of this Section 4.4 (including, without
limitation, the adoption and amendment of applicable benefit plans and
arrangements). SBC and BellSouth shall cause their respective Leasing Companies
to be participating employers, as of the Closing Date, in the SBC Compensation
and Benefit Plans and the BellSouth Compensation and Benefit Plans, as the case
may be, which provide compensation and employee benefits to the Transferred
Employees (as defined below) immediately prior to the Closing Date.

                  (b) Following the formation of the Leasing Companies, and on a
date (such date, the "Transfer Date") prior to the Closing Date, SBC and
BellSouth each respectively agree, to the extent it has the unilateral right to,
and to the extent it does not have the unilateral right to, to use its
reasonable best efforts to cause all Persons employed by either of them or any
affiliate of either of them whose employment is primarily related to the SBC
Business or the BellSouth Business, as the case may be, as of the Transfer Date
(or such earlier date as the transfer of employment occurs) to become employed
not later than the Transfer Date by the applicable Leasing Company (such
employees, collectively, the "Transferred Employees"). The Transferred Employees
shall be employed at rates of compensation and with employee benefits which are
substantially equivalent to the respective rates of compensation and benefits
paid or provided to such Transferred Employees immediately prior to the Closing.
Only the Transferred Employees and individuals hired following the Transfer Date
whose employment is primarily related to the SBC Business or the BellSouth
Business, as the case may be, shall be employed by the Leasing Companies.
Employees so employed by the SBC Leasing Company will be referred to herein as
"SBC Wireless Employees" and

                                      -56-
<PAGE>   62
employees so employed by the BellSouth Leasing Company are referred to as
"BellSouth Wireless Employees."

                  (c) The SBC Leasing Company shall, as of the Transfer Date,
assume (i) all employment-related obligations and liabilities (without regard to
when such obligations and liabilities arise or are incurred whether before or
after the Transfer Date), including all obligations and liabilities under the
SBC Compensation and Benefit Plans for which representations and warranties have
been made in Section 3.1(i) herein, in respect of the SBC Wireless Employees as
of the date each such employee becomes employed by the SBC Leasing Company, and
(ii) all employment-related obligations and liabilities (without regard to when
such obligations and liabilities arose or were incurred whether before or after
the Transfer Date) in respect of former employees whose employment was primarily
related to the SBC Business prior to the Closing Date (but excluding obligations
and liabilities relating to former employees under tax-qualified defined
contribution and defined benefit plans).

                  (d) The BellSouth Leasing Company shall, as of the Transfer
Date, assume (i) all employment-related obligations and liabilities (without
regard to when such obligations and liabilities arise or are incurred whether
before or after the Transfer Date), including all obligations and liabilities
under the BellSouth Compensation and Benefit Plans for which representations and
warranties have been made in Section 3.2(i) herein, in respect of the BellSouth
Wireless Employees as of the date each such employee becomes employed by the
BellSouth Leasing Company, and (ii) all employment-related obligations and
liabilities (without regard to when such obligations and liabilities arose or
were incurred whether before or after the Transfer Date) in respect of former
employees whose employment was primarily related to the BellSouth Business prior
to the Closing Date (but excluding obligations and liabilities relating to
former employees under tax-qualified defined contribution and defined benefit
plans).

                  (e) From time to time prior to the Leasing Company
Contribution Date, Newco shall have the sole discretion to select which of the
Transferred Employees of the SBC Leasing Company and the BellSouth Leasing
Company (the "Leased Employees") will cease to provide services to Newco prior
to the Leasing Company Contribution Date. Leased Employees so selected shall at
the discretion of the Leasing Company employing such Person be terminated by the
Leasing Companies or transferred by the Leasing Companies to SBC or BellSouth or
one of their Affiliates, as the case may be, in each case prior to the Leasing
Company Contribution Date. Notwithstanding any other provisions of this
Agreement to the contrary, including Sections 4.4(c) and 4.4(d), (i) all
employment related obligations and liabilities in respect of any Leased Employee
transferred to SBC, BellSouth or any of their Affiliates pursuant to the
preceding sentence shall cease to be an obligation or liability of the Leasing
Company and become the sole responsibility and obligation of SBC, BellSouth or
such Affiliates, as applicable, and

                                      -57-
<PAGE>   63
(ii) neither the Leasing Companies nor Newco shall have any liabilities or
obligations under any SBC Compensation and Benefit Plan or BellSouth
Compensation and Benefit Plan, as the case may be, that is a severance plan in
respect of a Leased Employee whose employment with a Leasing Company and all of
its affiliates is terminated prior to the Leasing Company Contribution Date.

                  (f) Following the Closing Date, Newco shall reimburse each of
the BellSouth Leasing Company and the SBC Leasing Company for all employment
expenses, out-of-pocket expenses and related costs associated with the provision
of services by the Transferred Employees. All reimbursements will be determined
and made in a manner consistent with the determination of reimbursements under
the Leasing Agreements. Such expenses and costs shall include, but are not
limited to (i) all costs incurred by the Leasing Companies associated with
payroll services to be provided hereunder (including (A) gross wages before
deductions for state and federal income taxes, employment taxes and other tax
deductions and before reductions for pre-tax salary deferrals related to Code
Sections 401(k) and 125 plans and plans of executive compensation, and (B)
employer's share of Federal Social Security taxes (FICA) and Federal
Unemployment Insurance taxes (FUTA)); (ii) all costs associated with and arising
out of the provision of benefits to the Leased Employees and their dependents as
contemplated in Sections 4.4(c) and 4.4(d) other than cash severance payments as
described in Section 4.4(e) (all expenses incurred by the Leasing Companies in
the payment and processing of benefit claims, costs associated with
administering denied claims, premiums and premium taxes); and (iii) all costs
and expenses relating to the relocation of Transferred Employees that are
relocated at the request of Newco. Promptly after the date hereof, BellSouth and
SBC shall agree on a reciprocal retention program for the Transferred Employees,
which program shall be subject to reimbursement in accordance with this Section
4.4(f).

                  (g) On or prior to December 31, 2001 or such other date as the
parties agree (the "Leasing Company Contribution Date"), each of SBC and
BellSouth shall cause to be contributed to Newco all of the outstanding stock of
or other equity interests in the respective Leasing Companies in consideration
of the acceptance by Newco of the obligations and liabilities of the Leasing
Companies; it being understood that both contributions shall be made on the same
Business Day. The Leasing Companies shall cease participating in (or otherwise
provide benefits under) the SBC Compensation and Benefit Plans and BellSouth
Compensation and Benefit Plans, as applicable, as of the Leasing Company
Contribution Date and shall commence to participate in (or otherwise provide
benefits under) the Newco Plans established pursuant to Section 4.4(k) hereof.

                  (h) SBC and BellSouth shall cause Newco to establish a
severance policy, effective as of and following the Leasing Company Contribution
Date. Newco shall bear and be responsible for all obligations and liabilities
under such policy as to the

                                      -58-
<PAGE>   64
employees of the Leasing Companies and Newco on and after the Leasing Company
Contribution Date.

                  (i) Unless the parties agree otherwise, the assets and
liabilities of the SBC Wireless Employees and the BellSouth Wireless Employees
held under their respective Pension Plans with Code Section 401(k) features
("401(k) Plans") to be transferred to the Newco 401(k) Plan in a trust-to-trust
transfer as soon as practicable following the later of (i) the Leasing Company
Contribution Date and (ii) the date that Newco has demonstrated, to the
reasonable satisfaction of BellSouth or SBC, as applicable, that the Newco
401(k) Plan satisfies the qualification requirements of Section 401 of the Code.

                  (j) If the Parties agree, the Parties, the SBC Leasing
Company, the BellSouth Leasing Company, and Newco shall take all actions
necessary to cause the assets and liabilities corresponding to the SBC Wireless
Employees and the BellSouth Wireless Employees held under any defined benefit
Pension Plans to be transferred to a Newco Pension Plan on a projected benefit
obligation basis at the Leasing Company Contribution Date or as of a later date
determined to be permissible under the appropriate Pension Plan documents (such
transfers to be effected on the basis of actuarial assumptions agreed to by
BellSouth and SBC).

                  (k) Newco shall establish and sponsor, or cause to be
established and sponsored, Compensation and Benefit Plans (the "Newco Plans")
which are separate from the BellSouth Compensation and Benefit Plans and the SBC
Compensation and Benefit Plans. The Newco Plans shall provide that the SBC
Wireless Employees and the BellSouth Wireless Employees and each other person
who becomes an employee of Newco or any of its Subsidiaries subsequent to the
Closing Date upon a direct transfer of employment from SBC, a Subsidiary of SBC,
BellSouth or a Subsidiary of BellSouth shall be credited with such years of
service with SBC, a Subsidiary of SBC, BellSouth, or a Subsidiary of BellSouth
for purposes of eligibility, participation, and determining the level of
benefits (but not benefit accrual) under the Newco Plans.

                  (l) From and after the Leasing Company Contribution Date,
Newco shall indemnify, defend and hold harmless each of BellSouth and SBC and
the affiliates of each of them and hold BellSouth and SBC and the affiliates of
each of them harmless from and against any Losses which may be incurred or
suffered by any of them in connection with the obligations and liabilities of
the Leasing Companies and the obligations and liabilities assumed by Newco
relating to compensation and employee benefits (whether arising in connection
with the transactions contemplated by this Section 4.4, or otherwise). In
addition, from and after the Leasing Company Contribution Date, (i) BellSouth
agrees to indemnify, defend and hold harmless Newco from and against all Losses
arising out of or relating to the BellSouth Leasing Company, other than the

                                      -59-

                                    and the BellSouth Benefits Liabilities (the
                                    "Statement").

                                    (y) After receipt of the Statement, SBC and

                                    their authorized representatives reasonable
                                    access during normal business hours and
                                    without significant disruption to their
                                    respective business to (i) all of their and
                                    their Subsidiaries' respective books,
                                    records and employees having relevant
                                    information concerning the calculation of
                                    the Statement to the extent that such
                                    information was used in the calculation of
                                    the Statement, and (ii) the accountants and
                                    actuaries who assisted Newco in preparing
                                    the calculation of the Statement and such
                                    accountants' and actuaries' relevant
                                    supporting workpapers. Unless SBC or
                                    BellSouth delivers written notice to Newco
                                    and to SBC or BellSouth, as the case may be,
                                    on or prior to the 60th day after Newco's
                                    delivery of the Statement stating that SBC
                                    or BellSouth, as the case may be, has
                                    objections to the Statement and describing
                                    any such objections with reasonable
                                    particularity, SBC and BellSouth shall be
                                    deemed to have accepted and agreed to the
                                    calculation of the Statement. In addition,
                                    any item included in the

                                      -61-
<PAGE>   67
                                    Statement which is not objected to by either
                                    SBC or BellSouth shall be deemed to be
                                    accepted by SBC and BellSouth and any
                                    amounts included within any such item shall
                                    be deemed to be final, binding and
                                    conclusive. If SBC or BellSouth notifies
                                    Newco of its objections to the calculation,
                                    SBC, BellSouth and Newco shall, within ten
                                    (10) days, attempt to resolve their
                                    differences, and any written resolution by
                                    them as to any disputed amounts shall be
                                    final, binding and conclusive on all parties
                                    for all purposes.

                                    (z) Any amounts remaining in dispute at the
                                    conclusion of the seventieth (70th) day
                                    following the delivery of the Statement
                                    shall be submitted, within ten (10) days
                                    after the expiration of such period, to

                                    by the Parties. Each Party agrees to
                                    execute, if requested by such firm, an
                                    engagement letter with such firm containing
                                    reasonable terms. All fees and expenses
                                    relating to the work, if any, to be
                                    performed by such firm shall be borne by the
                                    Parties equally. Such firm shall act as an
                                    arbitrator and not as an expert in resolving
                                    any disputed items hereunder. Such firm's
                                    determination of such items shall be made
                                    within thirty (30) days after the submission
                                    of such items to such firm. Such firm's
                                    resolution of such disputed items shall be
                                    set forth in a written statement delivered
                                    to the parties and shall be final, binding
                                    and conclusive on all parties for all
                                    purposes.

                           (iii)    Payment.

                                    (x) In the event that the BellSouth

                                    BellSouth shall make a cash payment to Newco
                                    equal to the quotient of (A) divided by (B),
                                    where (A) is the excess of (I) the BellSouth
                                    Benefits Liabilities over (II) the product
                                    of the Total Benefits Liabilities and .40

                                    cash payment to Newco equal to the quotient
                                    of (A) divided by (B), where (A) is the
                                    excess of (I) the SBC Benefits Liabilities
                                    over (II) the

continue to operate such businesses. The Parties acknowledge that following the
Closing, Newco shall be required to cause any such assets, rights or interests
to be transferred, conveyed or assigned to SBC or a Person designated by SBC as
soon as practicable after receiving written notice from SBC that it or any of
its Subsidiaries is in possession of any such assets, rights or interests. In
each case, SBC or the Person designated by SBC shall not be required to pay
consideration in respect of the transfer, conveyance or assignment referred to
in the preceding sentence.

                  (b) Notwithstanding anything to the contrary contained herein,
prior to Closing, BellSouth shall be permitted to cause to be transferred,
conveyed or assigned to BellSouth or any other Person designated by BellSouth,
any assets, rights or interests primarily related to the Excluded BellSouth

continue to operate such businesses. The Parties acknowledge that following the
Closing, Newco shall be required to cause any such assets, rights or interests

         4.6 Divestitures. In the event that any properties or assets of either
of the Parties or their Subsidiaries are required to be divested (such
properties or assets, "Conflicted Systems") under the CMRS station spectrum
aggregation limits established by the FCC in 47 C.F.R. Section 20.6 and the
Cellular Cross Ownership Limits contained in 47 C.F.R. Section 22.942 (together,
the "Overlap Laws"), the Parties shall establish a committee (the "Disposition
Committee") comprised of one member representing BellSouth and one member
representing SBC, which shall determine within 45 days after the date hereof
which Conflicted Systems will be required to be disposed (the "Disposition
Systems"). The Parties may cause some or all of the Disposition Systems to

                                      -63-
<PAGE>   69
be marketed as a single transaction or in such other manner as the Disposition
Committee shall determine will be in the best interests of Newco and the Party
making the divestiture. With respect to each of the Disposition Systems, the
Party which is, or whose Affiliate is, the holder of a Person which is the
current licensee of such Disposition System, shall, with the approval of the
other Party, (i) take all reasonably necessary steps to conclude a binding
agreement to transfer such Disposition System as promptly as practicable at a
reasonable price, (ii) file all necessary applications for all Governmental
Approvals required to consummate such transfer, (iii) seek such applications and
the satisfaction of any other conditions to closing such transaction promptly,
diligently and in good faith; provided that nothing set forth in this Section

take place concurrently with (or earlier, if the selling Party consents in
writing) the Closing.

         4.7 Acquisitions by SBC or BellSouth. Notwithstanding any action
permitted to be taken by Sections 4.2(a) and 4.2(b) hereof, SBC and BellSouth
shall not, and shall cause their Subsidiaries (other than the SBC Companies and
their Subsidiaries and the BellSouth Companies and their Subsidiaries) not to
purchase or otherwise become the owner of, or enter into an agreement to
purchase or otherwise become the owner of any property or assets that would
result in the SBC Contribution and the BellSouth Contribution causing Newco to
be in violation of the Overlap Laws, if not divested prior to the Closing.

         4.8 Accountants' Letter. SBC shall use its reasonable best efforts, to
obtain a letter from Ernst & Young LLP or another nationally recognized
independent accounting firm, dated the Closing Date, addressing whether or not
the consummation of the transactions contemplated hereby will require SBC to
restate the accounting for any of the transactions set forth on Schedule 4.8 of
the SBC Disclosure Letter from a "pooling-of-interests" transaction to a
"purchase" transaction; provided that the failure of SBC to use its reasonable
best efforts to obtain such a letter shall not constitute a breach of this
covenant if the condition in Section 5.3(e) shall have been waived or deemed
waived.

         4.9 Transition Group. Promptly after the date hereof, the Parties will
create a transition group (the "Transition Group") to consist of at least one
marketing executive, one technical executive, one financial executive, one human
resources executive, one regulatory executive and one designated team leader

Group will have responsibility for developing and implementing transitional
arrangements until the Closing, including, without limitation, issues with
respect to Newco relating to technology, human resources, wireless coverage
area, service offerings to be made available after the Closing and marketing.
The financial members of the Transition Group will also work together to assist
in the preparation of pro forma financial statements required by the Parties in

                                      -64-

SBC shall prepare an initial marketing plan covering the balance of the year
2000 (if the Closing is to occur in the year 2000) and all of the year 2001 that

next succeeding sentence, the Agency Agreements. The Parties agree, between the
date hereof and the Closing Date, to negotiate in good faith with respect to any
revisions the Parties may suggest with respect to the Agency Agreements. If the
Parties agree to any such revisions, the term Agency Agreements shall be deemed
to be the Agency Agreements as so revised.

business shall be determined by the Transition Group.

         4.15 Branding; Corporate Name. (a) Prior to Closing the Parties shall

                  (b) The Parties agree that they shall promptly meet after the
date hereof to agree upon Newco's company name following the Closing. The
Parties agree that Newco's company name following the Closing will not be
directly or indirectly tied to either SBC or BellSouth or to any of their
respective Subsidiaries or Affiliates. Newco shall do business under a company
name that will reflect Newco's broad geographic strategy of local, regional and
national wireless coverage and future wireless opportunities in voice, data,
Internet and other telecommunications services. The Parties will ensure that
such name shall be the exclusive property of Newco, and no Party shall have any
right to use, and each Party agrees not to use, such name other than on behalf
of

                                      -65-

those intercompany arrangements (i) set forth in the Ancillary Agreements, (ii)
as otherwise agreed by the Parties in writing, (iii) intercompany obligations

otherwise agreed by the Parties in writing, (iii) intercompany obligations for

         4.17 Taxes. (a) SBC Liability for Pre-Closing Taxes. SBC shall be
liable for and indemnify Newco for all Taxes imposed on the SBC Companies or
their Subsidiaries or for which the SBC Companies or their Subsidiaries may
otherwise by liable for any taxable year or period that ends on or before the
Closing Date and, with respect to any taxable year or period beginning before
and ending after the Closing Date, the portion of such taxable year ending on
and including the Closing Date. Except as set forth in paragraph (d), SBC shall

the BellSouth Companies or any of their respective Subsidiaries for a portion of
a taxable year or period that begins before and ends after the Closing Date, the
determination of the Taxes of the relevant entity for the portion of the year or
period ending on, and the portion of the year or period beginning after, the
Closing Date shall be determined by assuming that the relevant entity had a
taxable year or period which ended at the close of the Closing Date, except that
exemptions, allowances or deductions that are calculated on an annual basis,
such as the deduction for depreciation and Taxes on real or personal property,
shall be apportioned on a daily basis.

                  (d) Refunds from SBC Carrybacks. If SBC becomes entitled to a
refund or credit of Taxes for any period for which it is liable under Section
4.17(a) to indemnify Newco and such Taxes are attributable solely to the
carryback of losses, credits or similar items attributable to the SBC Companies
or their Subsidiaries and from a taxable year or period that begins after the
Closing Date, SBC shall promptly pay to Newco the amount of such refund or
credit together with any interest thereon. In the event that any refund or
credit of Taxes for which a payment has been made is subsequently reduced or
disallowed, SBC and BellSouth shall cause Newco to indemnify and hold harmless
SBC for any tax liability, including interest and penalties, assessed against
SBC by reason of the reduction or disallowance. SBC and BellSouth will cause
Newco to waive this carryback option, if possible.

                  (e) Refunds from BellSouth Carrybacks. If BellSouth becomes
entitled to a refund or credit of Taxes for any period for which it is liable
under Section 4.17(b) to indemnify Newco and such Taxes are attributable solely
to the carryback of losses, credits or similar items attributable to the

begins after the Closing Date, BellSouth shall promptly pay to Newco the amount
of such refund or credit together with any interest thereon. In the event that
any refund or credit of Taxes for which a payment has been made is subsequently
reduced or disallowed, SBC and BellSouth shall cause Newco to indemnify and hold
harmless BellSouth for any tax liability, including interest and penalties,
assessed against BellSouth by reason of the reduction or disallowance. SBC and
BellSouth will cause Newco to waive this carryback option, if possible.

                  (f) SBC Tax Returns. SBC shall file or cause to be filed when
due all Tax Returns that are required to be filed by or with respect to the SBC

claim or asset that is by its terms or by Law non-assignable without the consent
of any other Person, unless such consent or approval shall have been given.

         4.25 Further Assurances. At any time following the Closing Date, SBC

the transactions contemplated hereby under the HSR Act and the EU Merger
Regulation shall have expired or been earlier terminated, and (ii) all SBC
Required Consents and BellSouth Required Consents, the failure of which to be
made or obtained would be reasonably likely, individually or in the aggregate,

(as the case may be) pursuant to a Final Order, free of any conditions (other
than conditions that (x) would not be reasonably likely, individually or

                                      -71-
<PAGE>   77
in the aggregate, to have a Material Adverse Effect on Newco following the
Closing, and (y) would not be reasonably likely to be material and adverse to
any material business of SBC or BellSouth, as the case may be, that is not
included in the SBC Business or the BellSouth Business). For the purposes of
this Agreement, "Final Order" means an action or decision that has been granted
as to which (i) no request for a stay or any similar request is pending, no stay
is in effect, the action or decision has not been vacated, reversed, set aside,
annulled or suspended and any deadline for filing such a request that may be
designated by statute or regulation has passed, (ii) no petition for rehearing
or reconsideration or application for review is pending and the time for the
filing of any such petition or application has passed, (iii) no Governmental
Entity has undertaken to reconsider the action on its own motion and the time
within which it may initiate such reconsideration has passed, and (iv) no appeal
is pending or in effect and any deadline for filing any such appeal that may be

seeking any such Order.

         5.2 Conditions to Obligation of BellSouth. The obligation of BellSouth
to consummate the transactions contemplated by this Agreement is further subject
to the satisfaction or due waiver by BellSouth at or prior to the Closing of

the consent or approval of each Person whose consent or approval shall be
required in order to consummate the transactions contemplated by this Agreement
under any Contract to which the SBC Companies or any of their Subsidiaries is a
party, except those for which the failure to obtain such consent or approval is

         and

                           (ii) this Agreement and the Ancillary Agreements to
         be executed by SBC have been validly authorized, duly executed and

forth on Schedule 4.10(a) of the SBC Disclosure Letter from a
"pooling-of-interests" transaction to a "purchase" transaction; provided that
this condition shall be deemed to have been satisfied if SBC shall have been
required to restate the accounting for any of such transactions whether or not
the transactions contemplated hereby are consummated.

                  (f) BellSouth shall have furnished to SBC the opinion of
in-house counsel for BellSouth, dated the Closing Date, to the effect that:

                          SURVIVAL AND INDEMNIFICATION

         7.1 Survival of Representations, Warranties, Covenants and Agreements;
Knowledge of Breach. Except as set forth in this Section 7.1, the
representations and warranties contained in this Agreement shall expire on the
eighteenth month anniversary of the Closing Date (provided that with respect to
the SBC Additional Subsidiaries and the BellSouth Additional Subsidiary, the
relevant eighteenth month anniversary shall be the eighteenth month following
the applicable SBC Additional Closing or BellSouth Additional Closing, as the
case may be). The representations and warranties included or provided for (x) in
Sections 3.1(m) and 3.2(m) (Tax Matters) herein shall survive the Closing until
the expiration of the applicable statute of limitations (including any waivers
or extensions thereof) with respect to such matters and shall expire at such
time, (y) in Sections 3.1(k) and 3.2(k) (Environmental Matters) shall survive
until the third anniversary of the Closing Date (provided that with respect to
the SBC Additional Subsidiaries and the BellSouth Additional Subsidiary, the
relevant third anniversary shall be the third anniversary following the
applicable SBC Additional Closing or BellSouth Additional Closing, as the case
may be) and shall expire at such time, and (z) in Sections 3.1(a) and 3.2(a)
(Organization, Good Standing and Qualification), 3.1(c) and 3.2(c)
(Capitalization), 3.1(d) and 3.2(d) (Subsidiaries), 3.1(e) and 3.2(e) (Corporate
Authority and Approval) and 3.1(q) and 3.2(q) (Brokers and Finders) shall have
no expiration date. In the event that any Claim Notice or any other written
notice of a claim shall be given hereunder within the applicable survival
period, the representations and warranties that are the subject of such
indemnity claim shall survive until such claim is finally resolved but only with
respect to such claim and any directly related matters. The covenants and other
agreements contained in this Agreement shall survive the Closing until the date
or dates specified therein or the expiration of the applicable statute of
limitations (including any waivers or extensions thereof) with respect to such
matters, whichever is later.

         7.2 Indemnification by BellSouth. (a) For the period commencing on the
Closing Date and ending, as the case may be, upon the expiration of the periods
specified in Section 7.1, BellSouth shall, subject to the limitations set forth
in Section 7.1 and this Section 7.2, indemnify, defend and hold harmless Newco
and its Affiliates (other than SBC and BellSouth), and their respective
directors, officers, employees, shareholders and agents (the "Indemnified
Parties") against and in respect of all losses, damages (excluding punitive and
consequential damages other than for lost profits), liabilities, costs and
expenses (including reasonable attorneys' fees and expenses incurred in
investigating, preparing or defending any claims covered hereby) (collectively,
"Losses")

                                      -76-
<PAGE>   82
sustained or incurred arising out of, in connection with or relating to any
breaches of any of BellSouth's representations and warranties set forth in this
Agreement (disregarding for purposes of this Article VII all qualifications and
exceptions contained therein relating to materiality (including Material Adverse
Effect)); provided, that no individual Loss or series of related Losses arising
out of, in connection with or relating to any breaches of any of BellSouth's
representations and warranties set forth in this Agreement shall be deemed to be
a Loss until the amount of such Loss or series of related Losses exceeds
$2,000,000 and then only the amount in excess of $2,000,000 shall be deemed a
Loss. In determining whether a representation or warranty set forth in this
Agreement has been breached, the matters set forth in the BellSouth Disclosure
Schedule that qualify the accuracy of a representation or warranty shall be
disregarded; provided that with respect to a Loss or a series of related Losses
arising out of a representation or warranty as to which disclosure to qualify
such a representation or warranty has been made on BellSouth Disclosure Schedule
there shall be no Loss until the amount of such Loss or series of related Losses
exceeds $4,000,000 and then only the amount in excess of $4,000,000 shall be
deemed a Loss.

                  (b) BellSouth shall not be liable for any Losses arising in
connection with a breach of BellSouth's representations and warranties set forth
in this Agreement unless and until the amount of such Losses sustained or
incurred by the Indemnified Parties arising out of, in connection with or
relating to any breaches of BellSouth's representations and warranties set forth
in this Agreement exceeds $250 million in the aggregate (the "BellSouth
Deductible"), it being understood that for purposes of calculating whether the
BellSouth Deductible has been met, the losses of equity holders shall not be
counted if a similar Loss of Newco arising out of or related to the same breach
of a representation or warranty has been included in such calculation. If the
aggregate amount of such Losses exceeds the BellSouth Deductible, BellSouth
shall be liable only for the amount by which such Losses exceed the BellSouth
Deductible. In addition, except for breaches of Sections 3.1(c) and 3.2(c)
(Capitalization), 3.1(d) and 3.2(d) (Subsidiaries), 3.1(f) and 3.2(f) (Financial
Statements), 3.1(m) and 3.2(m) (Taxes) and 3.1(q) and 3.2(q) (Brokers and
Finders) for which there shall be no limit, any payments under this Section 7.2
by BellSouth to the Indemnified Parties for Losses shall not exceed in the
aggregate $3 billion.

         7.3 Indemnification by SBC. (a) For the period commencing on the
Closing Date and ending, as the case may be, upon the expiration of the periods
specified in Section 7.1, SBC shall, subject to the limitations set forth in
Section 7.1 and this Section 7.3, indemnify, defend and hold harmless the
Indemnified Parties against and in respect of all Losses sustained or incurred
arising out of, in connection with or relating to any breaches of any of SBC's
representations and warranties set forth in this Agreement (disregarding for
purposes of this Article VII all qualifications and exceptions contained therein
relating to materiality (including Material Adverse Effect); provided, that no

                                      -77-
<PAGE>   83
individual Loss or series of related Losses arising out of, in connection with
or relating to any breaches of any of SBC's representations and warranties set
forth in this Agreement shall be deemed to be a Loss until the amount of such
Loss or series of related Losses exceeds $2,000,000 and then only the amount in
excess of $2,000,000 shall be deemed a Loss. In determining whether a
representation or warranty set forth in this Agreement has been breached, the
matters set forth in the BellSouth Disclosure Schedule that qualify the accuracy
of a representation or warranty shall be disregarded; provided that with respect
to Loss or a series of related Losses arising out of a representation or
warranty as to which disclosure to qualify such representation or warranty has
been made on SBC Disclosure Schedule there shall be no Loss until the amount of
such Loss or series of related Losses exceeds $4,000,000 and then only the
amount in excess of $4,000,000 shall be deemed a Loss.

                  (b) SBC shall not be liable for any Losses arising in
connection with a breach of SBC's representations and warranties set forth in
this Agreement unless and until the amount of such Losses sustained or incurred
by the Indemnified Parties arising out of, in connection with or relating to any
breaches of SBC's representations and warranties set forth in this Agreement
exceeds $250 million in the aggregate (the "SBC Deductible"), it being
understood that for purposes of calculating whether the SBC Deductible has been
met, the losses of equity holders shall not be counted if a similar Loss of
Newco arising out of or related to the same breach of a representation or
warranty has been included in such calculation. If the aggregate amount of such
Losses exceeds the SBC Deductible, SBC shall be liable only for the amount by
which such Losses exceed the SBC Deductible. In addition, except for breaches of
Sections 3.1(c) and 3.2(c) (Capitalization), 3.1(d) and 3.2(d) (Subsidiaries),
3.1(f) and 3.2(f) (Financial Statements), 3.1(m) and 3.2(m) (Taxes) and 3.1(q)
and 3.2(q) (Brokers and Finders) for which there shall be no limit, any payments
under this Section 7.3 by SBC to the Indemnified Parties for Losses shall not
exceed in the aggregate $3 billion.

         7.4 Indemnification as Sole Remedy; Specific Performance. Following the
Closing, the indemnities provided in this Article VII and in Section 4.17 shall
be the sole and exclusive remedy of the Parties hereto, their Affiliates,
successors and assigns with respect to any and all claims for Losses sustained
or incurred arising out of, in connection with or relating to this Agreement and
the transactions contemplated by this Agreement, except for damages for breach
of any covenants, agreements (other than any covenant or agreement providing for
the maintenance of the accuracy of representations or warranties) or wilful or
fraudulent breach of the representations and warranties set forth in this
Agreement or any of the other agreements contemplated hereby. Notwithstanding
the foregoing, a Party hereto may seek specific performance of the obligations
set forth in Article II and Section 4.18 (Business Assets) of this Agreement.

<PAGE>   84
         7.5 Method of Asserting Claims, Etc. All claims for indemnification by
the Indemnified Party hereunder shall be asserted and resolved as set forth in
this Section 7.5. In the event that any written claim or demand for which SBC or
BellSouth, as the case may be (an "Indemnifying Party"), may be liable to any
Indemnified Party hereunder is asserted against or sought to be collected from
any Indemnified Party by a third party, such Indemnified Party shall promptly,
but in no event later than 15 days following such Indemnified Party's receipt of
such claim or demand, notify in writing the Indemnifying Party of such claim or
demand (the "Claim Notice"). The Indemnifying Party shall be relieved of its
obligations to indemnify the Indemnified Party with respect to such claim or
demand if the Indemnified Party fails to timely deliver the Claim Notice and the
Indemnifying Party is materially prejudiced thereby. The Indemnifying Party
shall have 30 days after the personal delivery or mailing of the Claim Notice,
whichever is later, (the "Notice Period") to notify the Indemnified Party
whether or not it desires to defend the Indemnified Party against such claim or
demand and shall during the Notice Period and thereafter be provided by the
Indemnified Party with such information relating to the claim or demand as the
Indemnifying Party shall request. All costs and expenses incurred by the
Indemnifying Party in defending such claim or demand shall be borne by the
Indemnifying Party. Except as hereinafter provided, in the event that the
Indemnifying Party notifies the Indemnified Party within the Notice Period that
it desires to defend the Indemnified Party against such claim or demand, the
Indemnifying Party shall have the sole power to direct and control such defense.
If the Indemnifying Party so elects to assume the defense of such claim, the
Indemnifying Party shall not be liable to the Indemnified Party for any legal
expenses subsequently incurred by the Indemnified Party, except as hereinafter
provided. The Indemnifying Party shall be liable for the reasonable fees and
expenses of the Indemnified Party in connection with the defense of a Claim if
the Indemnified Party shall have been advised in writing by outside counsel that
there are actual conflicts of interests between the Indemnified Party and the
Indemnifying Party in connection with the defense of such Claim; provided,
however, that the Indemnifying Party shall not be responsible for the fees and
expenses of more than one separate firm of attorneys at any time for all
Indemnified Parties. If any Indemnified Party desires to participate in, but not
control, any such defense it may do so at its sole cost and expense (except as
provided in the preceding sentence), provided, that in any action seeking an
injunction or decree which would restrict the future activity or conduct of the
Indemnified Party or any Subsidiary or Affiliate thereof, the Indemnified Party
shall be entitled to participate in the defense of such action at the expense of
the Indemnifying Party. The Indemnified Party shall not settle, compromise or
discharge a claim or demand for which it is indemnified by the Indemnifying
Party or admit to any liability with respect to such claim or demand without the
prior written consent of the Indemnifying Party. The Indemnifying Party shall
not, without the written consent of the Indemnified Party settle, compromise or
offer to settle or compromise any such claim or demand on a basis which would
result in the imposition of a consent order, injunction or decree which would
restrict the future activity or conduct of the Indemnified Party or any
Subsidiary or

                                      -79-
<PAGE>   85
Affiliate thereof. To the extent the Indemnifying Party shall direct, control or
participate in the defense or settlement of any third party claim or demand, the
Indemnified Party will provide the Indemnifying Party and its counsel access to
all relevant business records and other documents, and shall use its reasonable
best efforts to assist, and to cause the employees and counsel of the
Indemnified Party to assist, in defense of such claim. If the Indemnifying Party
elects not to defend the Indemnified Party, the Indemnified Party shall have the
right and the obligation to defend the claim or demand by appropriate
proceedings and shall have the sole power to direct and control such defense.

         7.6 No Additional Recoveries. No indemnity shall be recoverable by the
Indemnified Parties with respect to any matter to the extent such matter was
reflected in (i) the final calculation of the Closing Net Debt, if any, pursuant
to Section 2.11 or (ii) the Benefits Calculation, if any, pursuant to Section
4.4(i) and any Losses related thereto to the extent reflected in the final
calculation of the adjustment to the Closing Net Debt or the Benefits True-Up,
as the case may be, shall not be counted as Losses.

         7.7 Calculation of Losses. The amount of any Losses payable by the
Indemnifying Party to the Indemnified Party shall be net of any (i) amounts
recovered or recoverable by the Indemnified Party under applicable insurance
policies, (ii) Tax cost incurred by the Indemnified Party arising from the
receipt of indemnity payments and (iii) Tax benefit realized by the Indemnified
Party arising from the incurrence or payment of any such Loss, but only to the
extent of such Loss. In computing the amount of any such Tax cost or Tax
benefit, the Indemnified Party shall be deemed to fully utilize all Tax items
arising from the receipt of any indemnity payment hereunder or the incurrence or
payment of any indemnified Loss. Nothing in this Section 7.6 shall require SBC
or BellSouth to disclose any information regarding the calculation of Taxes
(including, without limitation, any Tax Return), other than to the extent such
information relates directly to the computation of Tax cost or Tax benefit for
these purposes.

         7.8 Assignment of Claims. If the Indemnified Party receives any payment
from an Indemnifying Party in respect of any Losses and the Indemnified Party
could have recovered all or a part of such Losses from a third party (a
"Potential Contributor") based on the underlying claim or demand asserted
against the Indemnifying Party, the Indemnified Party shall, to the extent
permitted by Law or any applicable contractual arrangement, assign such of its
rights to proceed against the Potential Contributor as are necessary to permit
the Indemnifying Party to recover from the Potential Contributor the amount of
such payment.

         7.9 Tower Indemnity. For the period commencing on the Closing Date and
ending on the fourth anniversary thereof, SBC shall indemnify, defend and hold
harmless the Indemnified Parties against and in respect of all Losses sustained,
incurred, arising out of, in connection with or relating to the Tower Bankruptcy
of the lessor of any

                                      -80-
<PAGE>   86
Towers that are subject to and part of the Tower Transaction (as defined in
Schedule 4.2 of the SBC Disclosure Letter) (each, a "Tower Lessor"); provided
that if the counterparty to the Tower Transaction is described as on Schedule
7.9 of the SBC Disclosure Letter the maximum amount of Losses related to the
foregoing for which SBC may be liable shall not exceed 50% of the proceeds
received by SBC or its Subsidiaries by the Tower Lessor in connection with the
Tower Transaction; and provided further that such indemnification shall not
apply if the Tower Transaction is substantially similar to the arrangement
described on Schedule 3.2(o)(D) of the BellSouth Disclosure Letter. The
indemnification procedures set forth in the preceding Sections of this Article
VII shall apply to any indemnifications under this Section 7.9.

                                  ARTICLE VIII
                                  MISCELLANEOUS

         8.1 Amendment and Waiver. Any provision of this Agreement may be
amended or waived if, and only if, such amendment or waiver is in writing and
signed, in the case of an amendment, by SBC and BellSouth, or in the case of a
waiver, by the party against whom the waiver is to be effective. No failure or
delay by any party in exercising any right, power or privilege hereunder shall
operate as a waiver thereof nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege.

         8.2 Expenses. Except as otherwise expressly provided in this Agreement,
whether or not the transactions contemplated by this Agreement are consummated,
the Parties shall bear their own respective expenses (including, but not limited
to, Transfer Taxes and all compensation and expenses of counsel, financial
advisors, consultants, actuaries and independent accountants) incurred in
connection with this Agreement and the transactions contemplated hereby.

         8.3 Public Disclosure. The Parties to this Agreement hereby agree with
the other party hereto that prior to the Closing, except as may be required to
comply with the requirements of applicable Law or the rules and regulations of
any national securities exchange upon which the securities of one of the Parties
or its Affiliates is listed, no press release or similar public announcement or
communication will be made or caused to be made concerning the execution or
performance of this Agreement unless specifically approved in advance by all
parties hereto; provided, however, that to the extent that either party to this
Agreement is required by Law or the rules and regulations of any stock exchange
upon which the securities of one or more of the parties or its Affiliates is
listed to make such a public disclosure, such public disclosure shall only be
made after prior consultation with and delivery of a copy of the proposed
disclosure substantially in the

                                      -81-
<PAGE>   87
form it will be disclosed to the public to the other party to this Agreement, if
consultation and delivery is reasonably practicable.

         8.4 Assignment. No Party may assign any of its rights or obligations
under this Agreement without the prior written consent of the other Party
hereto; provided that any Party may assign this Agreement to a wholly owned
Subsidiary so long as the Party assigning this Agreement agrees to guarantee,
without restriction, the performance of all such Subsidiary's obligations
hereunder.

         8.5 Entire Agreement. This Agreement and the Ancillary Agreements
(including all Annexes, Exhibits and Schedules hereto and thereto) contain the
entire agreement between the parties hereto with respect to the subject matter
hereof and supersede all prior agreements and understandings, oral or written,
with respect to such matters, except for the Confidentiality Agreement which
will remain in full force and effect for the term provided for therein.

         8.6 Fulfillment of Obligations. Any obligation of any Party to any
other Party under this Agreement, which obligation is performed, satisfied or
fulfilled by an Affiliate of such Party, shall be deemed to have been performed,
satisfied or fulfilled by such Party.

         8.7 Parties in Interest; No Third Party Beneficiaries. This Agreement
shall inure to the benefit of and be binding upon the Parties hereto and their
respective successors and permitted assigns. Nothing in this Agreement, express
or implied, is intended to confer upon any Person other than SBC, BellSouth,
Newco or their respective successors any rights or remedies under or by reason
of this Agreement.

         8.8 Counterparts. This Agreement and any amendments hereto may be
executed in one or more counterparts, each of which shall be deemed to be an
original by the parties executing such counterpart, but all of which shall be
considered one and the same instrument.

         8.9 Section Headings. The section and paragraph headings and table of
contents contained in this Agreement are for reference purposes only and shall
not in any way affect the meaning or interpretation of this Agreement.

         8.10 Notices. All notices or other communications hereunder shall be

         8.11 Governing Law; Submission to Jurisdiction; Selection of Forum.
THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS
OF THE STATE OF DELAWARE WITHOUT REFERENCE TO THE CHOICE OF LAW PRINCIPLES
THEREOF. EACH PARTY HERETO AGREES THAT IT SHALL BRING ANY ACTION OR PROCEEDING
IN RESPECT OF ANY CLAIM ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE
TRANSACTIONS CONTAINED IN OR CONTEMPLATED BY THIS AGREEMENT, WHETHER IN TORT OR
CONTRACT OR AT LAW OR IN EQUITY, EXCLUSIVELY IN THE COURTS OF THE STATE OF
DELAWARE AND THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA LOCATED IN THE
STATE OF DELAWARE (THE "CHOSEN COURTS").

         8.12 Submission to Jurisdiction. Each of SBC, BellSouth and Newco
hereby irrevocably submits in any action, suit or proceeding arising out of this
Agreement or any of the transactions contemplated hereby to the exclusive
jurisdiction of the courts of the State of Delaware and the Federal courts of
the United States of America located in the State of Delaware. The Parties
hereto irrevocably waive, to the fullest extent permitted by law, any objections
which they may now or hereafter have to the laying of the venue of any such
action, suit or proceeding in any such court or that any such action, suit or
proceeding which is brought in any such court has been brought in an
inconvenient

                                      -84-
<PAGE>   90
forum. Process in any such action, suit or proceeding may be served on any Party
anywhere in the world, whether within or without the jurisdiction of any such
court.

         8.13 Waiver of Jury Trial. Each Party acknowledges and agrees that any
controversy which may arise under this Agreement is likely to involve
complicated and difficult issues, and therefore each such Party hereby
irrevocably and unconditionally waives any right such Party may have to a trial
by jury in respect of any litigation directly or indirectly arising out of or
relating to this Agreement, or the transactions contemplated by this Agreement.
Each Party certifies and acknowledges that (i) no representative, agent or
attorney of any other Party has represented, expressly or otherwise, that such
other Party would not, in the event of litigation, seek to enforce the foregoing
waiver, (ii) each such Party understands and has considered the implications of
this waiver, (iii) each such Party makes this waiver voluntarily and (iv) each
such Party has been induced to enter into this Agreement by, among other things,
the mutual waivers and certifications in this Section 8.13.

         8.14 Severability. The provisions of this Agreement shall be deemed
severable and the invalidity or unenforceability of any provision shall not
affect the validity or enforceability of the other provisions hereof unless such
invalidity or unenforceability, after taking into account the mitigation
contemplated by the next sentence, deprives a party of a material benefit
contemplated by this Agreement. If any provision of this Agreement, or the
application thereof to any Person or any circumstance, is invalid or
unenforceable, (a) a suitable and equitable provision shall be substituted
therefor in order to carry out, so far as may be valid and enforceable, the
intent and purpose of such invalid or unenforceable provision and (b) the
remainder of this Agreement and the application of such provision to other
persons, entities or circumstances shall not be affected by such invalidity or
unenforceability, nor shall such invalidity or unenforceability affect the
validity or enforceability of such provision, or the application thereof, in any
other jurisdiction.

the

                                       2

<PAGE>   3

Company may designate by notice to the holder hereof). The Company agrees
and acknowledges that the shares of Common Stock so purchased shall be deemed to
be issued to the presenting Warrantholder as the record owner of such shares as
of the close of business on the date on which this Warrant, properly endorsed,
and the Subscription Form shall have been surrendered and payment made for such
shares. Upon receipt thereof, the Company shall, as promptly as practicable,
execute or cause to be executed and deliver to the Warrantholder, a certificate
or certificates representing the aggregate number of shares of Common Stock
specified in said Subscription Form. Each stock certificate so delivered shall
be in such denomination as may be requested by the Warrantholder and shall be
registered in the name of the Warrantholder. If this Warrant shall have been
exercised only in part, the Company shall, at the time of delivery of said stock
certificate or certificates, deliver to the Warrantholder a new Warrant
evidencing the rights of such holder to purchase the remaining shares of Common
Stock covered by this Warrant. The Company shall pay all expenses, taxes and
other charges payable in connection with the preparation, execution and delivery
of stock certificates pursuant to this Section 2, except that, in case any such
stock certificate or certificates shall be registered in a name or names other
than the name of the Warrantholder, funds sufficient to pay all stock transfer
taxes which shall be payable upon the execution and delivery of such stock
certificate or certificates shall be paid by the Warrantholder to the Company at
the time of delivering this Warrant to the Company as mentioned above.

         3.       Ownership of this Warrant. The Company may deem and treat the
registered Warrantholder as the holder and owner hereof (notwithstanding any
notations of ownership or writing made hereon by anyone other than the Company)
for all purposes and shall not be affected by any notice to the contrary, until
presentation of this Warrant for transfer as provided herein and then only if
such transfer meets the requirements of Section 5 hereof

         4.       Exchange, Transfer and Replacement. Subject to Section 5
hereof, this Warrant is exchangeable upon the surrender hereof by the
Warrantholder to the Company at its office or agency described in Section 2
hereof for new Warrants of like tenor and date representing in the aggregate the
right to purchase the number of shares purchasable hereunder, each of such new
Warrants to represent the right to purchase such number of shares (not to exceed
the aggregate total number purchasable hereunder) as shall be designated by the
Warrantholder at the time of such surrender. Subject to Section 5 hereof, this
Warrant and all rights hereunder are transferable, in whole or in part, upon the
books of the Company by the Warrantholder in person or by duly authorized
attorney, and a new Warrant of the same tenor and date as this Warrant, but
registered in the name of the transferee, shall be executed and delivered by the
Company upon surrender of this Warrant, duly endorsed, at said office or agency
of the Company. Upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction, or mutilation of this Warrant, and, in
case of loss, theft, or destruction, of indemnity or security reasonably
satisfactory to it, and upon surrender and cancellation of this Warrant, if
mutilated, the Company will make and deliver a new Warrant of like tenor, in
lieu of this Warrant. This Warrant shall be promptly canceled by the Company
upon the surrender hereof in connection with any exchange, transfer or
replacement. The Company shall pay all expenses, taxes (other than stock
transfer taxes), and other charges payable in connection with the preparation,
execution, and delivery of Warrants pursuant to this Section 4.

         5.       Restrictions on Transfer. Notwithstanding any provisions
contained in this Warrant to the contrary, neither this Warrant, nor the Warrant
Shares, shall be transferable except upon the conditions specified in this
Section 5, which conditions are intended, among other things, to ensure
compliance with the provisions of the Securities Act in respect of the transfer
of this Warrant or such Warrant Shares. The holder of this Warrant agrees that
such holder will not transfer this Warrant, nor the related Warrant Shares: (a)
prior to delivery to the Company of an opinion of counsel satisfactory to the
Company and its counsel stating that such transfer is exempt from registration
under the Securities Act and applicable state securities laws; or (b) until
registration of such Warrants and/or Warrant Shares under the Securities Act has
become effective and continues to be effective at the time of such transfer. An
appropriate legend may be endorsed on the Warrants and the certificates
representing the Warrant Shares evidencing these restrictions, and a stop order
may be placed on the Company's transfer records.

         6.       Antidilution Provisions. The rights granted hereunder are
subject to the following:

                  (a)      Adjustment of Purchase Price. The Purchase Price
         shall be subject to adjustment from time to time as hereinafter
         provided. Upon each adjustment of the Purchase Price, the Warrantholder
         shall thereafter be entitled to purchase, at the Purchase Price
         resulting from such adjustment, the number of shares obtained by
         multiplying the Purchase Price in effect immediately prior to such
         adjustment by the number of shares purchasable pursuant hereto
         immediately prior to such adjustment and dividing the product thereof
         by the Purchase Price resulting from such adjustment;

                  (b)      Stock Split, Stock Dividends and Reverse Splits. In
         case the Company shall at any time divide the outstanding shares of its
         Common Stock into a greater number of shares (whether pursuant to a
         stock split, stock dividend or otherwise), and conversely, in case the
         outstanding shares of its Common Stock shall be combined into a smaller
         number of shares, the Purchase Price in effect immediately prior to
         such division or combination shall be proportionately adjusted to
         reflect the reduction or increase in the value of each such share of
         Common Stock;

                  (c)      Reorganization, Consolidation, Merger or Sale of
         Assets. If any capital reorganization or reclassification of the
         capital stock of the Company, or consolidation or merger of the Company
         with another corporation, or the sale of all or substantially all of
         its assets to another corporation shall be effected in such a way that
         holders of the Company's Common Stock shall be entitled to receive
         stock, securities or assets with respect to or in exchange for such
         common shares, then, as a condition of such reorganization,
         reclassification, consolidation, merger or sale, the holder of this
         Warrant shall have the right to purchase and receive upon the basis and
         upon the terms and conditions specified in this Warrant, and in lieu of
         the shares of the Common Stock of the Company immediately theretofore
         purchasable and receivable upon the exercise of the rights represented
         hereby, such shares of stock, other securities or assets as would have
         been issued or delivered to the holder of this Warrant if it had
         exercised this Warrant and had received such shares of

                                       4

<PAGE>   5

         Common Stock prior to such reorganization, reclassification,
         consolidation, merger or sale. The Company shall not effect any such
         consolidation, merger or sale, unless prior to the consummation thereof
         the successor corporation (if other than the Company) resulting from
         such consolidation or merger or the corporation purchasing such assets
         shall assume by written instrument executed and mailed to the
         registered holder of this Warrant at the last address of such holder
         appearing on the books of the Company, the obligation to deliver to
         such holder such shares of stock, securities or assets as, in
         accordance with the foregoing provisions, such holder may be entitled
         to purchase;

                  (d)      Other Actions. Provided, however, that the issuance
         of additional capital stock of the Company to persons other than the
         Warrantholder in a manner not discussed in this Section 6 shall not
         result in any adjustment in the Purchase Price or increase in the
         number of shares subject to this Warrant; and

                  (e)      Notice. Upon any adjustment of the Purchase Price,
         the Company shall give written notice thereof, by first class mail,
         postage prepaid, addressed to the registered Warrantholder at the
         address of such holder as shown on the books of the Company, which
         notice shall state the Purchase Price resulting from such adjustment
         and the increase or decrease, if any, in the number of shares
         purchasable at such price upon the exercise of this Warrant, setting
         forth in reasonable detail the method of calculation and the acts upon
         which such calculation is based.

                  7.       Special Agreements of the Company. The Company
         covenants and agrees that:

                  (a)      Will Reserve Shares. The Company will reserve and set
         apart and have at all times, free from preemptive rights, the number of
         shares of authorized but unissued Common Stock deliverable upon the
         exercise of the Warrants, and it will have at all times any other
         rights or privileges provided for herein sufficient to enable it at any
         time to fulfill all of its obligations hereunder;

                  (b)      Will Secure Governmental Approvals. If any shares of
         Common Stock required to be reserved for the purposes of exercise of
         the Warrants require registration with or approval of any governmental
         authority under any federal law (other than the Securities Act) or
         under any state law before such shares may be issued upon exercise of
         the Warrants, the Company, will, at its exercise of the Warrants, the
         Company will, at its expense, as expeditiously as possible, use its
         best efforts to cause such shares to be duly registered or approved, as
         the case may be;

                  (c)      Will Open Books. The Company will keep its books open
         for transfer of any Warrant and/or Warrant Shares except as otherwise
         provided by law; and

                  8.       Notices. Any notice or other document required or
         permitted to be given or delivered to Warrantholders shall be delivered
         or sent by certified mail to each

                                       5

<PAGE>   6

         Warrantholder at the last address shown on the books of the Company
         maintained for the registry and transfer of the Warrants. Any notice or
         other document required or permitted to be given or delivered to the
         Company shall be delivered or sent by certified mail to the principal
         office of the Company located at 8091 Wallace Road, Eden Prairie,
         Minnesota 55344, or such other address as shall have been furnished to
         the Warrantholders by the Company.

                  9.       No Rights as Shareholders: Limitation of Liability.
         This Warrant shall not entitle any holder hereof to any of the rights
         of a shareholder of the Company. No provision hereof, in the absence of
         affirmative action by the holder hereof to purchase shares of Common
         Stock, and no mere enumeration herein of the rights or privileges of
         the holder hereof, shall give rise to any liability of such holder for
         the Purchase Price or as a shareholder of the Company, whether such
         liability is asserted by the Company or by creditors of the Company.

                  10.      Governing Law. This Warrant shall be governed by, and
         construed under and in accordance with, the laws of the State of
         Minnesota.

                  11.      Miscellaneous. This Warrant and any provision hereof
         may be changed, waived, discharged or terminated only by an instrument
         in writing signed by the party (or any predecessor in interest thereof)
         against which enforcement of the same is sought. The headings in this
         Warrant are for purposes of reference only and shall not affect the
         meaning or construction of any of the provisions hereof.

         IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by
a duly authorized officer and attested effective the 1st day of April, 1998.

                     TO BE EXECUTED BY THE REGISTERED HOLDER
