 contemplated in the Merger Agreement is subject to the expiration or

 the receipt of other regulatory approvals, approval of the merger by the
 shareholders of Ameritech, approval of the issuance of common stock of SBC
 pursuant to the Merger Agreement by the shareholders of SBC and other

            4.2.    Exchange of Certificates for Shares.

                    (a) Exchange Procedures. Promptly after the Effective
Time, the Surviving Corporation shall cause an exchange agent selected by
SBC with the Company's prior approval, which shall not be unreasonably
withheld (the "Exchange Agent") to mail to each holder of record as of the
Effective Time of a Certificate or Registered Company Shares, as the case
may be, (other than holders of a Certificate or Registered Company Shares
in respect of Excluded Company Shares) (i) (x) in the case of holders of
Certificates, a letter of transmittal specifying that delivery shall be
effected, and that risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates (or affidavits of loss in lieu
thereof) to the Exchange Agent (the "Certificate Letter of Transmittal") or
(y) in the case of holders of Registered Company Shares, a letter of
transmittal specifying that the exchange for SBC Shares shall occur only
upon delivery of such letter of transmittal to the Exchange Agent (the
"Registered Letter of Transmittal"), each such letter of transmittal to be
in such form and have such other provisions as SBC and the Company
may reasonably agree, and (ii) instructions for exchanging Certificates or
Registered Company Shares for (A) uncertificated shares of SBC Common Stock
registered on the stock transfer books of SBC in the name of such holder
("Registered SBC Shares") or, at the election of such holder, certificates
representing shares of SBC Common Stock and (B) any unpaid dividends and
other distributions and cash in lieu of fractional shares. Subject to
Section 4.2(g), upon (I) surrender of a Certificate for cancellation to the
Exchange Agent together with a Certificate Letter of Transmittal, duly
executed, the holder of such Certificate or (II) upon delivery of a
Registered Letter of Transmittal, duly executed, the holder of such
Registered Company Shares, as the case may be, shall be entitled to receive
in exchange therefor (x) Registered SBC Shares or, at the election of such
holder, a certificate representing that number of whole shares of SBC
Common Stock that such holder is entitled to receive pursuant to this
Article IV, (y) a check in the amount (after giving effect to any required
tax withholdings) of (A) any cash in lieu of fractional shares determined
in accordance with Section 4.2(d) hereof plus (B) any cash dividends and
any other dividends or other distributions that such holder has the right
to receive pursuant to the provisions of this Article IV, and any
Certificate so surrendered and any Registered Company Share in respect of
which a Registered Letter of Transmittal is so delivered shall forthwith be
cancelled. No interest will be paid or accrued on any amount payable upon
due surrender of any Certificate or delivery of a duly executed Registered
Letter of Transmittal, as the case may be. In the event of a transfer of
ownership of Company Shares that is not registered in the transfer records
of the Company, Registered SBC Shares or a certificate representing the
proper number of shares of SBC Common Stock, as the case may be, together
with a check for any cash to be paid upon due surrender of the Certificate
or upon the delivery to the Exchange Agent of the duly executed Registered
Letter of Transmittal and any other dividends or distributions in respect
thereof, may be issued and/or paid to such a transferee if, in the case of
holders of Certificates, the Certificate formerly representing such Company
Shares is presented to the Exchange Agent, and, in the case of holders of
Registered Company Shares, if the Registered Letter of Transmittal is
delivered to the Exchange Agent in either case accompanied by all documents
required to evidence and effect such transfer and to evidence that any
applicable stock transfer taxes have been paid. If any Registered SBC
Shares or any certificate for shares of SBC Common Stock is to be issued in
a name other than that in which the Certificate surrendered in exchange
therefor or the Registered Company Shares exchanged therefor, as the case
may be, is registered, it shall be a condition of such exchange that the
Person (as defined below) requesting such exchange shall pay any transfer
or other taxes required by reason of the issuance of Registered SBC Shares
or a certificate for shares of SBC Common Stock in a name other than that
of the registered holder of the Certificate surrendered or the Registered
Company Shares exchanged, as the case may be, or shall establish to the
satisfaction of SBC or the Exchange Agent that such tax has been paid or is
not applicable.

            For the purposes of this Agreement, the term "Person" shall
mean any individual, corporation (including not-for-profit), general or
limited partnership, limited liability company, joint venture, estate,
trust, association, organization, Governmental Entity (as defined in
Section 5.1(d)(i)) or other entity of any kind or nature.

declared by SBC in respect of SBC Common Stock, the record date for which
is at or after the Effective Time, that declaration shall include dividends
or other distributions in respect of all shares of SBC Common Stock
issuable pursuant to this Agreement. No dividends or other distributions in
respect of such SBC Common Stock shall be paid to any holder of any
unsurrendered Certificate or Registered Company Shares for which a
Registered Letter of Transmittal shall not have been delivered, until such
Certificate is surrendered for exchange or such Registered Letter of
Transmittal is delivered, as the case may be, in accordance with this
Article IV. Subject to the effect of applicable laws, following surrender
of any such Certificate or delivery of any such Registered Letter of
Transmittal, as the case may be, there shall be issued and/or paid to the
holder of the Registered SBC Shares or the certificates representing whole
shares of SBC Common Stock, as the case may be, issued in exchange
therefor, without interest, (A) at the time of such surrender or delivery,
as the case my be, the dividends or other distributions with a record date
after the Effective Time and a payment date on or prior to the date of
issuance of such whole shares of SBC Common Stock and not previously paid
and (B) at the appropriate payment date, the dividends or other
distributions payable with respect to such whole shares of SBC Common Stock
with a record date after the Effective Time but with a payment date
subsequent to surrender or delivery, as the case may be. For purposes of
dividends or other distributions in respect of shares of SBC Common Stock,
all shares of SBC Common Stock to be issued pursuant to the Merger shall be
deemed issued and outstanding as of the Effective Time.

                    (ii) Registered holders of unsurrendered Certificates
or Registered Company Shares for which a duly executed Registered Letter of
Transmittal shall not have been delivered shall be entitled to vote after
the Effective Time at any meeting of SBC stockholders with a record date at
or after the Effective Time the number of whole shares of SBC Common Stock
represented by such Certificates or Registered Company Shares, as the case
may be, regardless of whether such holders have surrendered their
Certificates or delivered duly executed Registered Letters of Transmittal,
as the case may be.

                    (c) Transfers. After the Effective Time, there shall be
no transfers on the stock transfer books of the Company of the Company
Shares that were outstanding immediately prior to the Effective Time.

                    (d) Fractional Shares. Notwithstanding any other
provision of this Agreement, no fractional shares of SBC Common Stock will
be issued and any holder of Company Shares entitled to receive a fractional
share of SBC Common Stock but for this Section 4.2(d) shall be entitled to
receive an amount in cash (without interest) determined by multiplying such
fraction (rounded to the nearest onehundredth of a share) by the average of
the closing price of a share of SBC Common Stock, as reported in The Wall
Street Journal, New York City edition, on the trading day immediately prior
to the Effective Time.

                    (e) Termination of Exchange Period; Unclaimed Stock.
Any shares of SBC Common Stock and any portion of the cash, dividends or
other distributions with respect to the SBC Common Stock deposited by SBC
with the Exchange Agent (including the proceeds of any investments thereof)
that remain unclaimed by the stockholders of the Company 180 days after the
Effective Time shall be paid to SBC. Any stockholders of the Company who
have not theretofore complied with this Article IV shall thereafter look
only to SBC for payment of their shares of SBC Common Stock and any cash,
dividends and other distributions in respect thereof issuable and/or
payable pursuant to Section 4.1, Section 4.2(b) and Section 4.2(d) upon due
(i) surrender of (i) their Certificates (or affidavits of loss in lieu
thereof) or (ii) delivery of duly executed Registered Letters of
Transmittal, as the case may be, in each case with respect to both clause
(i) and (ii), without any interest thereon. Notwithstanding the foregoing,
none of SBC, the Surviving Corporation, the Exchange Agent or any other
Person shall be liable to any former holder of Company Shares for any
amount properly delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws.

                    (f) Lost, Stolen or Destroyed Certificates. In the
event any Certificate shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the Person claiming such Certificate
to be lost, stolen or destroyed and the posting by such Person of a bond in
the form customarily required by SBC as indemnity against any claim that
may be made against it with respect to such Certificate, SBC will issue the
shares of SBC Common Stock and the Exchange Agent will issue any cash,
dividends and other distributions in respect thereof issuable and/or
payable in exchange for such lost, stolen or destroyed Certificate pursuant
to Section 4.1, Section 4.2(b) and Section 4.2(d) upon due surrender of and
deliverable in respect of the Company Shares represented by such
Certificate pursuant to this Agreement, in each case, without interest.

                    (g) Affiliates. Notwithstanding anything herein to the
contrary, Certificates surrendered for exchange, or Registered Company
Shares to be exchanged pursuant to a Registered Letter of Transmittal
delivered, by any "affiliate" (as determined pursuant to Section 6.7) of
the Company shall not be exchanged until SBC has received a written
agreement from such Person as provided in Section 6.7 hereof.

            4.3. Dissenters' Rights. In accordance with Section 262 of the
DGCL, no appraisal rights shall be available to holders of Company Shares
in connection with the Merger.

            4.4. Adjustments to Prevent Dilution. In the event that prior
to the Effective Time there is a change in the number of Company Shares or
shares of SBC Common Stock or securities convertible or exchangeable into
or exercisable for Company Shares or shares of SBC Common Stock issued and
outstanding as a result of a distribution, reclassification, stock split
(including a reverse split), stock dividend or distribution, or other
similar transaction, the Exchange Ratio shall be equitably adjusted to
eliminate the effects of such event.

approvals, permits or authorizations required to be obtained by it from,
any governmental or regulatory authority, court, agency, commission, body
or other governmental entity ("Governmental Entity"), in connection with
the execution and delivery of this Agreement by it and the consummation by
it of the Merger and the other transactions contemplated hereby, except
those that the failure to make or obtain are not, individually or in the
aggregate, reasonably likely to have a Material Adverse Effect on it 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 Merger and
the other transactions contemplated hereby will not, constitute or result
in (A) a breach or violation of, or a default under, its certificate of
incorporation or by-laws or the comparable governing instruments of any of
its Significant Subsidiaries, (B) a breach or violation of, or a default
under, the acceleration of any obligations or the creation of a lien,
pledge, security interest or other encumbrance on its assets or the assets
of any of its Subsidiaries (with or without notice, lapse of time or both)
pursuant to, any agreement, lease, contract, note, mortgage, indenture,
arrangement or other obligation ("Contracts") binding upon it or any of its
Subsidiaries or, assuming the filings, notices and/or approvals referred to
in Section 5.1(d)(i) are made or obtained, any Law (as defined in Section
5.1(i)) or governmental or non-governmental permit or license to which it
or any of its Subsidiaries is subject or (C) any change in the rights or
obligations of any party under any of its Contracts, except, in the case of
clause (B) or (C) above, for any breach, violation, default, acceleration,
creation or change that, individually or in the aggregate, is not
reasonably likely to have a Material Adverse Effect on it or prevent,
materially delay or materially impair its ability to consummate the
transactions contemplated by this Agreement. The Company Disclosure Letter,
with respect to the Company, and the SBC Disclosure Letter, with respect to
SBC, sets forth a correct and complete list of Contracts of it and its
Subsidiaries pursuant to which consents or waivers are or may be required
prior to consummation of the transactions contemplated by this Agreement
other than those where the failure to obtain such consents or waivers is
not, individually or in the aggregate, reasonably likely to have a Material
Adverse Effect on it or prevent or materially impair its ability to
consummate the transactions contemplated by this Agreement.

                           (e) Reports; Financial Statements. It has made
available to the other party, each registration statement, report, proxy
statement or information statement prepared by it since December 31, 1997
(the "Audit Date"), including its Annual Report on Form 10-K for the year
ended December 31, 1997 in the form (including exhibits, annexes and any
amendments thereto) filed with the Securities and Exchange Commission (the
"SEC") (collectively, including any such reports filed subsequent to the
date hereof, its "Reports"). As of their respective dates, its Reports did
not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances in which they were
made, not misleading. Each of the consolidated balance sheets included in
or incorporated by reference into its Reports (including the related notes
and schedules) fairly presents the consolidated financial position of it
and its Subsidiaries as of its date and each of the consolidated statements
of income and of cash flows included in or incorporated by reference into
its Reports (including any related notes and schedules) fairly presents the
consolidated results of operations, retained earnings and cash flows, as
the case may be, of it and its Subsidiaries for the periods set forth
therein (subject, in the case of unaudited statements, to notes and normal
year-end audit adjustments that will not be material in amount or effect),
in each case in accordance with United States generally accepted accounting
principles ("GAAP") consistently applied during the periods involved,
except as may be noted therein. Since the Audit Date, it and each
Subsidiary required to make filings under Utilities Laws has filed with the
applicable PUCs or the FCC, as the case may be, all material forms,
statements, reports and documents (including exhibits, annexes and any
amendments thereto) required to be filed by them, and each such filing
complied in all material respects with all applicable laws, rules and
regulations, other than such failures to file and non-compliance that are,
individually or in the aggregate, not reasonably likely to have a Material
Adverse Effect on it or prevent or materially impair its ability to
consummate the transactions contemplated by this Agreement. To its
knowledge, as of the date hereof, no Person or "group" "beneficially owns"
5% or more of its outstanding voting securities, with the terms
"beneficially owns" and "group" having the meanings ascribed to them under
Rule 13d-3 and Rule 13d-5 under the Exchange Act.

                    (f) Absence of Certain Changes. Except as disclosed in
its Reports filed prior to the date hereof or as expressly contemplated or
permitted by this Agreement, since the Audit Date it and its Subsidiaries
have conducted their respective businesses only in, and have not engaged in
any material transaction other than according to, the ordinary and usual
course of such businesses and there has not been (i)any change in the
financial condition, properties, prospects, business or results of
operations of it and its Subsidiaries, except those changes that are not,
individually or in the aggregate, reasonably likely to have a Material
Adverse Effect on it; (ii) any damage, destruction or other casualty loss
with respect to any asset or property owned, leased or otherwise used by it
or any of its 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 it; (iii) any declaration,
setting aside or payment of any dividend or other distribution in respect
of its capital stock, except publicly announced regular quarterly cash
dividends on its common stock and, in the case of SBC, any dividends in
capital stock of SBC which are simultaneously taken into account in an
adjustment to the Exchange Ratio pursuant to Section 4.4; or (iv) any
change by it in accounting principles, practices or methods, except as
required by GAAP. Since the Audit Date, except as provided for herein, in
the Company Disclosure Letter, as disclosed in the Reports filed by the
Company prior to the date hereof or permitted hereby, there has not been
any increase in the salary, wage, bonus or other compensation payable or
that could become payable by the Company or any of its Subsidiaries to
directors, officers or key employees or any amendment of any of the Company
Compensation and Benefit Plans (as defined in Section 5.1(h)(i)) other than
increases or amendments in the ordinary course.

                    (g) Litigation and Liabilities. Except as disclosed in
its Reports filed prior to the date hereof, there are no (i) civil,
criminal or administrative actions, suits, claims, hearings, investigations
or proceedings pending or, to the actual knowledge of its executive
officers, threatened in writing against it or any of its Affiliates (as
defined in Rule 12b-2 under the Exchange Act) or (ii) obligations or
liabilities, whether or not accrued, contingent or otherwise and whether or
not required to be disclosed, including those relating to matters involving
any Environmental Law (as defined in Section 5.1(k)), or any other facts or
circum stances, in either such case, of which its executive officers have
actual 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 are not, individually or in the aggregate, reasonably likely to
have a Material Adverse Effect on it or prevent, materially delay or
materially impair its ability to consummate the transactions contemplated
by this Agreement; provided, however, that for purposes of this subsection
(g) no action, suit, claim, hearing, investigation or proceeding arising
after the date hereof shall be deemed to have any adverse effect if and to
the extent such actions, suits, claims, hearings, investigations or
proceedings are based on this Agreement or the transactions contemplated
hereby.

                    (h) Employee Benefits.

                            (i)     A copy 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 that covers
employees, directors, former employees or former directors of the Company
and its Subsidiaries (the "Company Compensation and Benefit Plans") and any
trust agreements or insurance contracts forming a part of such Company
Compensation and Benefit Plans has been made available by the Company to
SBC prior to the date hereof and each such Company Compensation and Benefit
Plan is listed in Section 5.1(h) of the Company Disclosure Letter.

                           (ii)     In the case of the Company,
each of the Company Compensation and Benefit Plans or, in the case of SBC,
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 that covers employees, directors, former employees or former
directors of SBC and SBC's Subsidiaries (together with the Company
Compensation and Benefit Plans, its "Compensation and Benefit Plans") is in
substantial compliance with all applicable law, including the Code and the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"). Each
of its Compensation and Benefit Plans that is an "employee pension benefit
plan" within the meaning of Section 3(2) of ERISA (a "Pension Plan") and
that is intended to be qualified under Section 401(a) of the Code has
received a favorable determination letter from the Internal Revenue Service
(the "IRS") with respect to "TRA" (as such term is defined in Section 1 of
Rev. Proc 9339), and it is not aware of any circumstances likely to result
in revocation of any such favorable determination letter. There is no
pending or, to the actual knowledge of its executive officers, threatened
in writing material litigation relating to its Compensation and Benefit
Plans. Neither it nor any Subsidiary has engaged in a transaction with
respect to any of its Compensation and Benefit Plans that, assuming the
taxable period of such transaction expired as of the date hereof, would
subject it or any of its 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
it or any Subsidiary 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 "ERISA Affiliate") (each such
single-employer plan, its "ERISA Affiliate Plan"). It and its Subsidiaries
and 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 its 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)     All contributions required to
be made under the terms of any of its Compensation and Benefit Plans as of
the date hereof have been timely made or have been reflected on the most
recent consolidated balance sheet filed or incorporated by reference in its
Reports prior to the date hereof. Neither any of its Pension Plans nor any
of any of its 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 it nor its Subsidiaries has provided, or is
required to provide, security to any of its Pension Plans or to any of its
ERISA Affiliate Plans pursuant to Section 401(a)(29) of the Code.

                            (v)     Under each of its Pension
Plans which is a single-employer plan and each of its 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
Pension Plan's or ERISA Affiliate Plan's most recent actuarial valuation),
did not exceed the then current value of the assets of such Pension Plan or
ERISA Affiliate Plan, and there has been no material change in the
financial condition of such Pension Plan or ERISA Affiliate Plan since the
last day of the most recent plan year.

                           (vi)     Neither it nor its Subsidiaries have any
obligations for retiree health and life benefits under any of its Compensatio
and Benefit Plans, except as set forth in its Reports filed prior to the
date hereof or as required by applicable law.

                           (vii) None of the consummation of the Merger and
the other transactions contemplated by this Agreement, in the case of SBC
and the Company, the adoption of this Agreement by the stockholders of the
Company, in the case of the Company, the approval by the stockholders of
SBC of the issuance of the shares of SBC Common Stock required to be issued
pursuant to Article IV, in the case of SBC, shall (x) entitle any of their
respective employees or directors or any employees of their respective
Subsidiaries to severance pay, directly or indirectly, upon termination of
employment, (y) accelerate the time of funding (whether through a grantor
trust or otherwise), 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 their respective Compensation
and Benefit Plans or (z) result in any breach or violation of, or a default
under, any of their respective Compensation and Benefit Plans.

                    (i) Compliance with Laws. Except as set forth in its
Reports filed prior to the date hereof, the businesses of each of it and
its Subsidiaries have not been, and are not being, conducted in violation
of any law, statute, ordinance, regulation, judgment, order, decree,
injunction, arbitration award, license, authorization, opinion, agency
requirement or permit of any Governmental Entity or common law
(collectively, "Laws"), except for violations or possible violations that
are not, individually or in the aggregate, reasonably likely to have a
Material Adverse Effect on it or prevent, materially delay or materially
impair its ability to consummate the transactions contemplated by this
Agreement. Except as set forth in its Reports filed prior to the date
hereof, no investigation or review by any Governmental Entity with respect
to it or any of its Subsidiaries is pending or, to the actual knowledge of
its executive officers, threatened, nor has any Governmental Entity
indicated an intention to conduct the same, except for those the outcome of
which are not, individually or in the aggregate, reasonably likely to have
a Material Adverse Effect on it or prevent, materially delay or materially
impair its ability to consummate the transactions contemplated by this
Agreement. To the actual knowledge of its executive officers, no material
change is required in its or any of its Subsidiaries' processes, properties
or procedures in connection with any such Laws, and it has not received any
notice or communication of any material noncompliance with any such Laws
that has not been cured as of the date hereof, except for such changes and
noncompliance that are not, individually or in the aggregate, reasonably
likely to have a Material Adverse Effect on it or prevent, materially delay
or materially impair its ability to consummate the transactions
contemplated by this Agreement. Each of it and its Subsidiaries has all
permits, licenses, franchises, variances, exemptions, orders and other
governmental authorizations, consents and approvals (collectively,
"Permits"), necessary to conduct their business as presently conducted,
except for those the absence of which are not, individually or in the
aggregate, reasonably likely to have a Material Adverse Effect on it or
prevent, materially delay or materially impair its ability to consummate
the transactions contemplated by this Agreement.

                    (j) Takeover Statutes. The Board of Directors of the
Company has taken all appropriate and necessary actions such that SBC will
not be prohibited from entering into a "business combination" with the
Company as an "interested stockholder" (in each case as such term is used
in Section 203 of the DGCL) as a result of the execution and delivery of
this Agreement or the consummation of the transactions contemplated hereby.
To the best knowledge of the Company, no other "fair price," "moratorium,"
"control share acquisition" or other similar anti-takeover statute or
regulation (each a "Takeover Statute") as in effect on the date hereof is
applicable to the Company, the Company Shares, the Merger or the other
transactions contemplated by this Agreement. No antitakeover provision
contained in the Company's certifi cate of incorporation, including Article
Ninth thereof, or its by-laws is, or at the Effective Time will be,
applicable to the Company, the Company Shares, the Merger or the other
transactions contemplated by this Agreement.

                    (k) Environmental Matters. Except as disclosed in its
Reports filed prior to the date hereof and except for such matters that,

is subject to any orders, decrees, injunctions or other arrangements with
any Governmental Entity or is subject to any indemnity or other agreement
with any third party relating to liability under any Environmental Law or
relating to Hazardous Substances; and (viii) there are no circumstances or
conditions involving it or any of its Subsidiaries that could reasonably be
expected to result in any claims, liability, investigations, costs or
restrictions on the ownership, use, or transfer of any of its properties
pursuant to any Environmental Law.

relating to: (A) the protection, investigation or restoration of the
environment, health, safety, or natural resources, (B) the handling, use,

neither it nor any of its affiliates (as determined in accordance with
Section 6.7) has taken or agreed to take any action, nor do its executive
officers have any actual knowledge of any fact or circumstance, that, to
their actual knowledge, would prevent SBC from accounting for the business
combination to be effected by the Merger as a "pooling-ofinterests" or
prevent the Merger and the other transactions contemplated by this
Agreement from qualifying as a "reorganization" within the meaning of
Section 368(a) of the Code.

                    (m) Taxes. It and each of its 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 (as
defined below) required to be filed by any of them and all such filed tax
returns are complete and accurate in all material respects and: (i) it and
each of its Subsidiaries have paid all Taxes (as defined below) that are
shown as due on such filed Tax Returns or that it or any of its

date hereof, there are not pending or, to the actual knowledge of its
executive officers threatened in writing, any audits, examinations,

Adverse Effect on it. No payments to be made to any of the officers and
employees of it or its Subsidiaries will as a result of consummation of the

amendment to the Rights Agreement (the "Rights Amendment") with the effect
that neither SBC nor Merger Sub shall be deemed to be an Acquiring Person

            6.1. Interim Operations. (a) The Company covenants and agrees
as to itself and its Subsidiaries that, after the date hereof and prior to
the Effective Time (unless SBC shall otherwise approve in writing, which
approval shall not be unreasonably withheld or delayed, and except as
otherwise expressly contemplated by this Agreement, disclosed in the
Company Disclosure Letter or required by applicable Law):

                            (i)     the business of it and its

associates;

                    (ii) it shall not (A) amend its certificate of
incorporation or by-laws or amend, modify or terminate the Rights
Agreement; provided, however, that nothing in this Agreement shall prevent
the Company from reducing below 20% the beneficial ownership threshold in
the definition of an Acquiring Person (as defined in the Rights Agreement)
or extending the Final Expiration Date of the Rights Agreement (as defined
therein) or adopting a new rights agreement having substantially similar
terms as the Rights Agreement and not inconsistent with (x) this proviso,

capital stock, but subject to the Company's obligations under subparagraph
(iii) below.

                          (iii)     neither it nor any of its
Subsidiaries shall knowingly take any action that would prevent the Merger

untrue in any material respect;

                           (iv)     neither it nor any of its
Subsidiaries shall terminate, establish, adopt, enter into, make any new

assets (including capital stock of any of its Subsidiaries) with a fair
market value in excess of $1 billion in the aggregate in any period of
twelve consecutive months following the date hereof except for transfers,
leases, licenses, sales, mortgages, pledges, encumbrances, or other
dispositions in the ordinary course of business consistent with past
practice;

                         (viii)     neither it nor any of its
Subsidiaries shall issue, deliver, sell, or encumber shares of any class of

hereafter under the Company Stock Plans in accordance with this Agreement
and shares issuable pursuant to such awards, and (B) up to an aggregate
amount of $3.6 billion of such shares, securities, rights, warrants or
options (valued at their fair market value as of the date of the agreement

acquisition or acquisitions permitted under clause (ix) below following
reasonable notice to SBC of its intention to take such action;

                           (ix)      neither it nor any of its

period of twelve consecutive months following the date hereof to acquire
any business, whether by merger, consolidation, purchase of property or

value as of the date of the agreement for such acquisition); provided, that
no such acquisition would prevent, materially delay or materially impair
its ability to consummate the transactions contemplated by this Agreement.
Notwithstanding the foregoing, neither it nor any of its Subsidiaries shall
acquire any business the acquisition of which would subject SBC and its
Subsidiaries following the consummation of the Merger to any Commercial

be conducted in the ordinary and usual course and, to the extent consistent
therewith, it and its Subsidiaries shall use all reasonable best efforts to
preserve its business organization intact and maintain its existing
relations and goodwill with customers, suppliers, regulators, distributors,
creditors, lessors, employees and business associates;

                           (ii)     it shall not (A) amend its

in no way be restricted by the foregoing; (B) declare, set aside or pay any

                          (iii)     neither it nor any of its
Subsidiaries shall knowingly take any action that would prevent the Merger
from qualifying for "poolingof interests" accounting treatment or as a
taxfree "reorganization" within the meaning of Section 368(a) of the Code
or that would cause any of its representations and warranties herein to
become untrue in any material respect;

                           (iv)     neither it nor any of its
Subsidiaries shall issue any SBC Preferred Shares or incur any indebtedness
for borrowed money or guarantee any such indebtedness if it should
reasonably anticipate that after such incurrence any of its or any of its
Subsidiaries' outstanding senior indebtedness would be rated A or lower by
Standard & Poor's;

                           (v) neither it nor any of its Subsidiaries shall

warrants or options to acquire, any such shares, except (A) any such shares
issued pursuant to options and other awards outstanding on the date hereof
under the SBC Stock Plans, awards of options and other awards granted
hereafter under the SBC Stock Plans and shares issuable pursuant to such
awards, (B) up to an aggregate amount of $4.8 billion of such shares,
securities, rights, warrants or options (valued at their fair market value
as of the date of the agreement to make such acquisition) in any period of
twelve consecutive months following the date hereof to fund, in whole or in
part, the cost of any acquisition or acquisitions permitted under clause
(viii) below, following reasonable notice to the Company of its intention
to take such action, and (C) pursuant to the terms of the Agreement and
Plan of Merger dated as of January 4, 1998, by and among Southern New
England Telecommunications Corporation ("SNET"), SBC and SBC(CT) Sub, Inc.

twelve consecutive months following the date hereof to acquire any
business, whether by merger, consolidation, purchase of property or assets

of the date of the agreement for such acquisition); provided, however, that
no such acquisition would prevent, materially delay or materially impair
its ability to consummate the transactions contemplated by this Agreement;
provided, further, that the SNET Agreement and the transactions
contemplated thereby shall not be subject to the terms of the foregoing
restriction. Notwithstanding the foregoing, neither it nor any of its
Subsidiaries shall acquire any business the acquisition of which would
subject SBC and its Subsidiaries following the consummation of the Merger
to any Commercial Mobile Radio Service spectrum aggregation limit
restriction pursuant to the provisions of 47 C.F.R. Section 20.6 or place
SBC and its Subsidiaries following the consummation of the Merger in
violation of the Cellular Cross Ownership limits contained in 47 C.F.R.
Section 22.942; provided, that, the SNET Agreement and the transactions
contemplated thereby shall not be subject to the terms of the foregoing
restriction. For purposes of this clause (viii), the amount spent with
respect to any acquisition shall be deemed to include the aggregate amount
of capital expenditures that the Company is obligated to make at any time
or plans to make as a result of such acquisition within two years after the
date of acquisition;

                           (ix) neither it nor any of its Subsidiaries

those businesses traditionally associated with the telecommunications
business; and

it nor any of its Subsidiaries shall, and that it shall direct and use its
best efforts to cause its and its Subsidiaries' employees, agents and
representatives (including any investment banker, attorney or accountant
retained by it or any of its Subsidiaries) (the Company, its Subsidiaries
and their officers, directors, employees, agents and representatives being
the "Company Representatives") not to, directly or indirectly, initiate,
solicit, encourage or otherwise facilitate any inquiries or the making of
any proposal or offer with respect to a merger, reorganization, share
exchange, consolidation or similar transaction involving, or any purchase
of, or tender offer for, any of the assets of it or any of its Subsidiaries
or its voting securities if, as a result of such transaction, (i) the
stockholders of the Company would not hold more than 50% of the voting
securities of the surviving corporation or its ultimate parent, (ii) the
directors of the Company would not constitute a majority of the board of
directors of the surviving corporation or its ultimate parent, or (iii)
another Person would acquire more than 50% of the assets of the Company and
its Subsidiaries (any such proposal or offer being hereinafter referred to
as a "Company Acquisition Proposal"). The Company further agrees that
neither it nor any of its Subsidiaries shall, and that it shall direct and
use its best efforts to cause the Company Representatives not to, directly
or indirectly, have any discussion with or provide any confidential
information or data to any Person relating to a Company Acquisition
Proposal or engage in any negotiations concerning a Company Acquisition
Proposal, or otherwise facilitate any effort or attempt to make or
implement a Company Acquisition Proposal; provided, however, that nothing
contained in this Agreement shall prevent either the Company or the Company
Representatives from (A) complying with Rule 14e-2 promulgated under the
Exchange Act with regard to a Company Acquisition Proposal; (B) engaging in
any discussions or negotiations with or providing any information to, any
Person in response to an unsolicited bona fide written Company Acquisition
Proposal by any such Person; or (C) recommending such an unsolicited bona
fide written Company Acquisition Proposal to the stockholders of the
Company if and only to the extent that, in such case referred to in clause
(B) or (C), (i) the Board of Directors of the Company concludes in good
faith (after consultation with its financial advisor) that such Company
Acquisition Proposal is reasonably capable of being completed, taking into
account all legal, financial, regulatory and other aspects of the proposal
and the Person making the proposal, and would, if consummated, result in a
transaction more favorable to the Company's stockholders from a financial
point of view than the transaction contemplated by this Agreement (any such
more favorable Company Acquisition Proposal being referred to in this
Agreement as a "Superior Company Proposal"), (ii) the Board of Directors of
the Company determines in good faith after consultation with outside legal
counsel that such action is necessary for the Board of Directors to comply
with its fiduciary duty under applicable law and (iii) prior to providing
any information or data to any Person in connection with a Company
Acquisition Proposal by any such Person, the Board of Directors of the
Company shall receive from such Person a confidentiality agreement in
customary form; provided, that such confidentiality agreement shall not
contain terms that prevent the Company from complying with its obligations
under this Section 6.2.

                    (b) SBC agrees that neither it nor any of its
Subsidiaries shall, and that it shall direct and use its best efforts to
cause its and its Subsidiaries' employees, agents and representatives
(including any investment banker, attorney or accountant retained by it or
any of its Subsidiaries) (SBC, its Subsidiaries and their officers,
directors, employees, agents and representatives being the "SBC
Representatives") not to, directly or indirectly, initiate, solicit,
encourage or otherwise facilitate any inquiries or the making of any
proposal or offer with respect to a merger, reorganization, share exchange,
consolidation or similar transaction involving, or any purchase of, or
tender offer for, all or any assets of it or any of its Subsidiaries or its
voting securities if, as a result of such transaction, (i) the stockholders
of SBC would not hold more than 50% of the voting securities of the
surviving corporation or its ultimate parent, (ii) the directors of SBC
would not constitute a majority of the board of directors of the surviving
corporation or its ultimate parent, or (iii) another Person would acquire
more than 50% of the assets of SBC and its Subsidiaries (any such proposal
or offer being hereinafter referred to as a "SBC Acquisition Proposal").
SBC further agrees that neither it nor any of its Subsidiaries nor any of
the officers and directors of it or its Subsidiaries shall, and that it
shall direct and use its best efforts to cause the SBC Representatives not
to, directly or indirectly, have any discussion with or provide any
confidential information or data to any Person relating to a SBC
Acquisition Proposal or engage in any negotiations concerning a SBC
Acquisition Proposal, or otherwise facilitate any effort or attempt to make
or implement a SBC Acquisition Proposal; provided, however, that nothing
contained in this Agreement shall prevent either SBC or the SBC
Representatives from (A) complying with Rule 14e-2 promulgated under the
Exchange Act with regard to a SBC Acquisition Proposal; (B) engaging in any
discussions or negotiations with or providing any information to, any
Person in response to an unsolicited bona fide written SBC Acquisition
Proposal by any such Person; or (C) recommending such an unsolicited bona
fide written SBC Acquisition Proposal to the stockholders of SBC if and
only to the extent that, in such cases referred to in clause (B) or (C),
(i) the Board of Directors of SBC concludes in good faith (after
consultation with its financial advisor) that such SBC Acquisition Proposal
is reasonably capable of being completed, taking into account all legal,
financial, regulatory and other aspects of the proposal and the Person
making the proposal, and would, if consummated, result in a transaction
more favorable to SBC or SBC's stockholders from a financial point of view
than the transaction contemplated by this Agreement (any such more
favorable SBC Acquisition Proposal being referred to herein as a "Superior
SBC Proposal"), (ii) the Board of Directors of SBC determines in good faith
after consultation with outside legal counsel that such action is necessary
for the Board of Directors to comply with its fiduciary duty under
applicable law and (iii) prior to providing any information or data to any
Person in connection with a SBC Acquisition Proposal by any such Person,
the Board of Directors of SBC shall receive from such Person a
confidentiality agreement in customary form; provided, that, such
confidentiality agreement shall not contain terms that prevent SBC from
complying with its obligations under this Section 6.2.

                    (c) The Company and SBC each agrees that it will
immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any parties conducted heretofore with
respect to any Company Acquisition Proposal or SBC Acquisition Proposal, as
the case may be. The Company and SBC each agrees that it will take the
necessary steps to promptly inform the individuals or entities referred to
in the first sentence of paragraphs (a) and (b), respectively, of the
obligations undertaken in Section 6.2(a) or (b), as the case may be. The
Company and SBC each agrees that it will notify the other immediately if
any such inquiries, proposals or offers are received by, any such
information is requested from, or any such discussions or negotiations are
sought to be initiated or continued with, any of its representatives
indicating, in connection with such notice, the name of such Person and the
terms and conditions of any proposals or offers, and thereafter shall
inform the other of any material modification of the terms of any such
proposal or offer or the withdrawal thereof. The Company and SBC each also
agrees that it will promptly request each Person that has heretofore
executed a confidentiality agreement in connection with its consideration
of any Company Acquisition Proposal or any SBC Acquisition Proposal, as the
case may be, to return all confidential information heretofore furnished to
such Person by or on behalf of it or any of its Subsidiaries.

            6.3. Information Supplied. The Company and SBC each agrees, as
to itself and its Subsidiaries, that none of the information supplied or to
be supplied by it or its Subsidiaries for inclusion or incorporation by
reference in (i) the Registration Statement on Form S-4 to be filed with
the SEC by SBC in connection with the issuance of shares of SBC Common
Stock in the Merger (including the joint proxy statement and prospectus
(the "Prospectus/Proxy Statement") constituting a part thereof) (the "S-4
Registration Statement") will, at the time the S-4 Registration Statement
becomes effective under the Securities Act, and (ii) the Prospectus/Proxy
Statement and any amendment or supplement thereto will, at the date of
mailing to stockholders and at the times of the meetings of stockholders of
the Company and SBC to be held in connection with the Merger, in any such
case, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they were
made, not misleading. If at any time prior to the Effective Time any
information relating to SBC or the Company, or any of their respective
affiliates, officers or directors, should be discovered by SBC or the
Company which should be set forth in an amendment or supplement to either
the S4 Registration Statement or the Prospectus/Proxy Statement, so that
any of such documents would not include any misstatement of a material fact
or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, the party which discovers such
information shall promptly notify the other parties hereto and an
appropriate amendment or supplement describing such information shall be
promptly filed with the SEC and, to the extent required by law,
disseminated to the stockholders of the Company and SBC.

            6.4. Stockholders Meetings. The Company will take, in
accordance with applicable law and its certificate of incorporation and
by-laws, all action necessary to convene a meeting of holders of Company
Shares (the "Company Stockholders Meeting") as promptly as practicable
after the S-4 Registration Statement is declared effective to consider and
vote upon the adoption of this Agreement. SBC will take, in accordance with
applicable law and its certificate of incorporation and by-laws, all action
necessary to convene a meeting of holders of the SBC Common Stock (the "SBC
Stockholders Meeting", and either the SBC Stockholders Meeting or the
Company Stockholders Meeting, a "Stockholders Meeting") as promptly as
practicable after the S-4 Registration Statement is declared effective to
consider and vote upon the approval of the issuance of SBC Common Stock
required to be issued pursuant to Article IV. Subject to fiduciary
obligations under applicable law and the terms of this Agreement, the
Company's Board of Directors shall recommend that the stockholders of the
Company adopt this Agreement and thereby approve the transactions
contemplated hereby and shall take all lawful action to solicit such
adoption, and SBC's Board of Directors shall recommend that the
stockholders of SBC approve the issuance of SBC Common Stock required to be
issued pursuant to Article IV and shall take all lawful action to solicit
such approval.

            6.5. Filings; Other Actions; Notification. (a) SBC and the
Company shall promptly prepare and file with the SEC the Prospectus/Proxy
Statement, and SBC shall prepare and file with the SEC the S-4 Registration
Statement as promptly as practicable. SBC and the Company each shall use
all reasonable best efforts to have the S-4 Registration Statement declared
effective under the Securities Act as promptly as practicable after such
filing, and promptly thereafter mail the Prospectus/Proxy Statement to the
respective stockholders of each of the Company and SBC. SBC shall also use
all reasonable best efforts to obtain prior to the effective date of the
S-4 Registration Statement all necessary state securities law or "blue sky"
permits and approvals required in connection with the Merger and to
consummate the other transactions contemplated by this Agreement and will
pay all expenses incident thereto.

                    (b) The Company and SBC each shall use all reasonable
best efforts to cause (x) the Merger to qualify for "pooling of interests"
accounting treatment and (y) to be delivered to the other party and its
directors a letter of its independent auditors, dated (i) the date on which
the S-4 Registration Statement shall become effective and (ii) the Closing
Date, and addressed to the other party and its directors, in form and
substance customary for "comfort" letters delivered by independent public
accountants in connection with registration statements similar to the S-4
Registration Statement.

                    (c) The Company and SBC shall cooperate with each other
and use (and shall cause their respective Subsidiaries to use) all their
respective reasonable best efforts to take or cause to be taken all
actions, and do or cause to be done all things, necessary, proper or
advisable on its part under this Agreement and applicable Laws to
consummate and make effective the Merger and the other transactions
contemplated by this Agreement as soon as practicable, including preparing
and filing as promptly as practicable all documentation to effect all
necessary applications, notices, petitions, filings and other documents and
to obtain as promptly as practicable all consents, registrations,
approvals, permits and authorizations required to be obtained from any
third party and/or any Governmental Entity in connection with the execution
and delivery of this Agreement and the consummation of the Merger and the
other transactions contemplated hereby; provided, however, that nothing in
this Section 6.5 shall require, or be construed to require, SBC or the
Company to agree to, or comply with, any conditions to the granting of any
such consent, registration, approval, permit or authorization by any
Governmental Entity if compliance with such conditions, individually or in
the aggregate, would be reasonably likely to have a Material Adverse Effect
on the Surviving Corporation or SBC following the Effective Time (it being
understood that, for this purpose only, materiality shall be determined by
reference to the trading market equity value of SBC prior to the
consummation of the Merger and after taking into account (i) any adverse
effects reasonably likely to arise from any restrictions on the ability of
the Surviving Corporation or SBC or any of their respective Subsidiaries to
conduct its operations as currently conducted or as proposed as of the date
of this Agreement to be conducted resulting from complying with the
conditions to or from the grant of any such consent, registration,
approval, permit or authorization, (ii) any benefits reasonably likely to
be realized by SBC on a consolidated basis (other than those operational
benefits reasonably likely to be realized directly from the consummation of
the Merger) resulting from complying with the conditions to or from the
grant of any such consent, registration, approval, permit or authorization,
and (iii) any proceeds resulting from any divestiture required by a
Governmental Entity as a condition to its granting any such consent,
registration, approval, permit or authorization); provided, further, that
any divestiture by either SBC or the Company or any of their respective
Subsidiaries reasonably required to cause the Surviving Corporation to be
in compliance with the Commercial Mobile Radio Service 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 shall be
deemed not to have any adverse effect on either the Surviving Corporation
or SBC following the Effective Time (a "Regulatory Material Adverse
Effect"). Subject to applicable laws relating to the exchange of
information, SBC and the Company shall have the right to review in advance,
and to the extent practicable each will consult the other on, all the
information relating to SBC or the Company, as the case may be, and any of
their respective Subsidiaries, that appear in any filing made with, or
written materials submitted to, any third party and/or any Governmental
Entity in connection with the Merger and the other transactions
contemplated by this Agreement. In exercising the foregoing right, each of
the Company and SBC shall act reasonably and as promptly as practicable.

                    (d) The Company and SBC each shall, upon request by the
other, furnish the other with all information concerning itself, its
Subsidiaries, directors, officers and stockholders and such other matters
as may be reasonably necessary or advisable in connection with the
Prospectus/Proxy Statement, the S-4 Registration Statement or any other
statement, filing, notice or application made by or on behalf of SBC, the
Company or any of their respective Subsidiaries to any third party and/or
any Governmental Entity in connection with the Merger and the transactions
contemplated by this Agreement.

                    (e) The Company and SBC each shall keep the other
apprised of the status of matters relating to completion of the
transactions contemplated hereby, including promptly furnishing the other
with copies of notice or other communications received by SBC or the
Company, as the case may be, or any of its Subsidiaries, from any third
party and/or any Governmental Entity with respect to the Merger and the
other transactions contemplated by this Agreement. Each of the Company and
SBC shall give prompt notice to the other of any change that is reasonably
likely to result in a Material Adverse Effect on it or of any failure of
any condition to the other party's obligations to effect the Merger set
forth in Article VII.

            6.6. Access; Consultation. (a) Upon reasonable notice, and
except as may otherwise be required by applicable law, the Company and SBC
each shall (and shall cause its Subsidiaries to) afford the SBC
Representatives or the Company Representatives, as the case may be,
reasonable access, during normal business hours throughout the period prior
to the Effective Time, to its properties, books, contracts and records and,
during such period, each shall (and shall cause its Subsidiaries to)
furnish promptly to the other all information concerning its business,
properties and personnel as may reasonably be requested, provided that no
investigation pursuant to this Section shall affect or be deemed to modify
any representation or warranty made by the Company, SBC or Merger Sub
hereunder, and provided, further, that the foregoing shall not require the
Company or SBC to permit any inspection, or to disclose any information,
that in the reasonable judgment of the Company or SBC, as the case may be,
would result in the disclosure of any trade secrets of third parties or
violate any of its obligations with respect to confidentiality if the
Company or SBC, as the case may be, shall have used all reasonable best
efforts to obtain the consent of such third party to such inspection or
disclosure. All requests for information made pursuant to this Section
shall be directed to an executive officer of the Company or SBC, as the
case may be, or such Person as may be designated by any such executive
officer, as the case may be.

                    (b) From the date hereof to the Effective Time, SBC and
the Company agree to consult with each other on a regular basis on a
schedule to be agreed with regard to their respective operations.

                    (c) From the date hereof to the Effective Time, the
Company agrees to notify SBC in advance of any issuance by the Company or
any of its Subsidiaries of any longterm debt in excess of $50 million,
Company Preferred Shares or Company Preference Shares.

            6.7. Affiliates. (a) Each of the Company and SBC shall deliver
to the other a letter identifying all Persons whom such party believes to
be, at the date of the Stockholders Meeting of such party, "affiliates" of
such party for purposes of applicable interpretations regarding use of the
poolingofinterests accounting method and, in the case of "affiliates" of
the Company, for purposes of Rule 145 under the Securities Act. Each of the
Company and SBC shall use all reasonable best efforts to cause each Person
who is identified as an "affiliate" in the letter referred to above to
deliver to SBC on or prior to the date of the Stockholders Meeting of such
party a written agreement, in the form attached hereto as Exhibit A, in the
case of affiliates of the Company (the "Company Affiliate's Letter"), and
Exhibit B, in the case of affiliates of SBC (the "SBC Affiliate's Letter").
Prior to the Effective Time, each of the Company and SBC shall use all
reasonable best efforts to cause each additional Person who is identified
as an "affiliate" after the date of the relevant Stockholders Meeting to
execute the applicable written agreement as set forth in this Section 6.7,
as soon as practicable after such Person is identified.

                    (b) If the Merger would otherwise qualify for
poolingofinterests accounting treatment, shares of SBC Common Stock issued
to such affiliates of the Company in exchange for Company Shares shall not
be transferable until such time as financial results covering at least 30
days of combined operations of SBC and the Company shall have been
published within the meaning of Section 201.01 of the SEC's Codification of
Financial Reporting Policies, regardless of whether each such affiliate has
provided the written agreement referred to in this Section, except to the
extent permitted by, and in accordance with, SEC Accounting Series Release
135 and SEC Staff Accounting Bulletins 65 and 76. Any Company Shares held
by any such affiliate shall not be transferable, regardless of whether such
affiliate has provided the applicable written agreement referred to in this
Section, if such transfer, either alone or in the aggregate with other
transfers by affiliates, would preclude SBC's ability to account for the
business combination to be effected by the Merger as a pooling of
interests. The Company shall not register the transfer of any Certificate,
unless such transfer is made in compliance with the foregoing.

            6.8. Stock Exchange Listing and De-listing. SBC shall use its
best efforts to cause the shares of SBC Common Stock to be issued in the
Merger to be approved for listing on the New York Stock Exchange ("NYSE"),
subject to official notice of issuance, prior to the Closing Date. The
Surviving Corporation shall use its best efforts to cause the Company
Shares to be de-listed from the NYSE and the Chicago, Boston, Pacific and
Philadelphia stock exchanges and de-registered under the Exchange Act as
soon as practicable following the Effective Time.

            6.9. Publicity. The initial press release with respect to the
Merger shall be a joint press release and thereafter the Company and SBC
shall consult with each other prior to issuing any press releases or
otherwise making public announcements with respect to the Merger and the
other transactions contemplated by this Agreement and prior to making any
filings with any third party and/or any Governmental Entity (including any
national securities exchange) with respect thereto, except as may be
required by law or by obligations pursuant to any listing agreement with or
rules of any national securities exchange.

            6.10.   Benefits.

                    (a) Stock Options.

                    (i) At the Effective Time, each outstanding option to
purchase Company Shares (a "Company Option") under the Company Stock Plans,
whether vested or unvested, shall be deemed to constitute an option to
acquire, on the same terms and conditions as were applicable under such
Company Option (except to the extent such terms and conditions are altered
in accordance with their terms as a result of the consummation of the
transactions contemplated by this Agreement), the same number of shares of
SBC Common Stock as the holder of such Company Option would have been
entitled to receive pursuant to the Merger had such holder exercised such
Company Option in full immediately prior to the Effective Time (rounded
down to the nearest whole number) (a "Substitute Option"), at an exercise
price per share (rounded up to the nearest whole cent)(the "Substitute
Option Price") equal to (y) the aggregate exercise price for the Company
Shares otherwise purchasable pursuant to such Company Option divided by (z)
the number of full shares of SBC Common Stock deemed purchasable pursuant
to such Company Option in accordance with the foregoing. For each
Substitute Option substituted for a Company Option that included a right
under certain circumstances to receive dividend equivalents in the form of
stock units ("Company Stock Units"), all Company Stock Units credited to
the account of the holder of such Substitute Option at the Effective Time
shall, as of the Effective Time, be deemed to constitute a number of stock
units, each of which shall represent one share of SBC Common Stock ("SBC
Stock Units"), equal to the number of shares of SBC Common Stock the holder
of such Substitute Option would have been entitled to receive pursuant to
this Agreement had such Company Stock Units been distributed to such holder
in full immediately prior to the Effective Time and thereafter SBC Stock
Units shall continue to be credited to the account of the holder of such
Substitute Option to the same extent and on the same terms and conditions
as they would have under the Company Option for which the Substitute Option
was substituted (except that the record dates and dividend amounts shall be
the record dates and dividend amounts for SBC Common Stock), and all such
SBC Stock Units shall be distributed at the same times and in the same
manner as the Company Stock Units would have been distributed had the
Substitute Option not been substituted for the Company Option (except that
the option price used to determine if the SBC Stock Units can be
distributed shall be the Substitute Option Price). At or prior to the
Effective Time, the Company shall make all necessary arrangements with
respect to the Company Stock Plans to permit the assumption of the
unexercised Company Options by SBC pursuant to this Section and as soon as
practicable after the Effective Time SBC shall use its best efforts to
register under the Securities Act on Form S-8 or other appropriate form
(and use its best efforts to maintain the effectiveness thereof) shares of
SBC Common Stock issuable pursuant to all Substitute Options.

                    (ii) Effective at the Effective Time, SBC shall assume
each Company Option in accordance with the terms of the Company Stock Plan
under which it was issued and the stock option agreement by which it is
evidenced. As promptly as practicable after the Effective Time, the Company
shall deliver to the participants in the Stock Plans appropriate notices
setting forth such participants' rights pursuant to such assumed Company
Options.

                    (b) Employee Benefits. SBC agrees that it shall cause
the Surviving Corporation for at least two years after the Effective Time
to provide or cause to be provided to employees of the Company and its
Subsidiaries compensation and benefit plans that are no less favorable, in
the aggregate, than the Company Compensation and Benefit Plans disclosed in
Section 6.10(b) of the Company Disclosure Letter; provided, however, if
during this period SBC implements any widespread increase or decrease in
benefits under compensation and benefit plans or in the cost thereof to
participants under compensation and benefit plans applicable to employees
of SBC and its Subsidiaries (other than the Surviving Corporation and its
Subsidiaries), the Surviving Corporation shall proportionately adjust the
benefits under the Company's compensation and benefit plans or the cost
thereof to participants, and provided, further with respect to employees
who are subject to collective bargaining, all benefits shall be provided
only in accordance with the applicable collective bargaining agreement. At
or prior to the Effective Time, the Company shall make all necessary
arrangements to cause any Company Share units under the Company's
Compensation and Benefit Plans to be converted into share units with
respect to SBC Common Stock by multiplying the Company Shares subject to
such Company Share units by the Exchange Ratio. SBC shall, and shall cause
the Surviving Corporation to, honor, pursuant to their terms, all employee
benefit obligations existing at the Closing Date to current and former
employees under the Company Compensation and Benefit Plans.

            6.11. Expenses. Whether or not the Merger is consummated, all
costs and expenses incurred in connection with this Agreement and the
Merger and the other transactions contemplated by this Agreement shall be
paid by the party incurring such expense, except that expenses incurred in
connection with the filing fee for the S-4 Registration Statement and
printing and mailing the Prospectus/Proxy Statement and the S-4
Registration Statement and the filing fee under the HSR Act shall be shared
equally by SBC and the Company.

            6.12. Indemnification; Directors' and Officers' Insurance. (a)
From and after the Effective Time, SBC shall, and shall cause the Surviving
Corporation to, indemnify and hold harmless each present and former
director and officer of the Company (when acting in such capacity)
determined as of the Effective Time (the "Indemnified Parties"), against
any costs or expenses (including reasonable attorneys' fees), judgments,
fines, losses, claims, damages or liabilities (collectively, "Costs")
incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative,
arising out of or pertaining to matters existing or occurring at or prior
to the Effective Time, whether asserted or claimed prior to, at or after
the Effective Time, to the fullest extent permitted under Delaware law (and
the Surviving Corporation shall also advance expenses as incurred to the
fullest extent permitted under applicable law, provided the Person to whom
expenses are advanced provides an undertaking to repay such advances if it
is ultimately determined that such Person is not entitled to
indemnification).

                    (b) Any Indemnified Party wishing to claim indemnification
under paragraph (a) of this Section 6.12, upon learning of any such claim,
action, suit, proceeding or investigation, shall promptly notify the
Surviving Corporation thereof, but the failure to so notify shall not
relieve the Surviving Corporation of any liability it may have to such
Indemnified Party if such failure does not materially prejudice the
Surviving Corporation. In the event of any such claim, action, suit,
proceeding or investigation (whether arising before or after the Effective
Time), (i) the Surviving Corporation shall have the right to assume the
defense thereof and the Surviving Corporation shall not be liable to such
Indemnified Parties for any legal expenses of other counsel or any other
expenses subsequently incurred by such Indemnified Parties in connection
with the defense thereof, except that if the Surviving Corporation elects
not to assume such defense or counsel for the Indemnified Parties advises
that there are issues which raise conflicts of interest between the
Surviving Corporation and the Indemnified Parties, the Indemnified Parties
may retain counsel satisfactory to them, and the Surviving Corporation
shall pay all reasonable fees and expenses of such counsel for the
Indemnified Parties promptly as statements therefor are received; provided,
however, that the Surviving Corporation shall be obligated pursuant to this
paragraph (b) to pay for only one firm of counsel for all Indemnified
Parties in any jurisdiction (unless there is a conflict of interest as
provided above) (ii) the Indemnified Parties will cooperate in the defense
of any such matter and (iii) the Surviving Corporation shall not be liable
for any settlement effected without its prior written consent.

                    (c) The Surviving Corporation shall maintain a policy
of officers' and directors' liability insurance for acts and omissions
occurring prior to the Effective Time ("D&O Insurance") with coverage in
amount and scope at least as favorable as the Company's existing directors'
and officers' liability insurance coverage for a period of six years after
the Effective Time; provided, however, if the existing D&O Insurance
expires, is terminated or cancelled, or if the annual premium therefor is
increased to an amount in excess of 175% of the last annual premium paid
prior to the date hereof (the "Current Premium"), in each case during such
six year period, the Surviving Corporation will use its best efforts to
obtain D&O Insurance in an amount and scope as great as can be obtained for
the remainder of such period for a premium not in excess (on an annualized
basis) of 175% of the Current Premium.

                    (d) If SBC or any of its successors or assigns (i)
shall consolidate with or merge into any other corporation or entity and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (ii) shall transfer all or substantially all of
its properties and assets to any individual, corporation or other entity,
then and in each such case, proper provisions shall be made so that the
successors and assigns of SBC shall assume all of the obligations set forth
in this Section.

                    (e) The provisions of this Section are intended to be
for the benefit of, and shall be enforceable by, each of the Indemnified
Parties, their heirs and their representatives.

            6.13. Takeover Statute. If any Takeover Statute is or may
become applicable to the Merger or the other transactions contemplated by
this Agreement, each of SBC and the Company and its Board of Directors
shall grant such approvals and take such actions as are necessary so that
such transactions may be consummated as promptly as practicable on the
terms contemplated by this Agreement or by the Merger and otherwise act to
eliminate or minimize the effects of such statute or regulation on such
transactions. The Company will cause the Rights Agent to promptly execute
the Rights Amendment.

            6.14. Dividends. The Company shall coordinate with SBC the
declaration, setting of record dates and payment dates of dividends on
Company Shares so that holders of Company Shares do not receive dividends
on both Company Shares and SBC Common Stock received in the Merger in
respect of any calendar quarter or fail to receive a dividend on either
Company Shares or SBC Common Stock received in the Merger in respect of any
calendar quarter.

            6.15. Confidentiality. The Company and SBC each acknowledges
and confirms that it has entered into a Confidentiality and NonDisclosure
Agreement, dated April 8, 1997 (the "Confidentiality Agreement"), that
information provided by each party hereto to the other party hereto
pursuant to this Agreement is subject to the terms of the Confidentiality
Agreement and that the Confidentiality Agreement shall remain in full force
and effect in accordance with its terms, except that notwithstanding any
provision to the contrary contained in the Confidentiality Agreement, the
Confidentiality Agreement shall not terminate until the earlier to occur of
the following: (i) the Effective Time and (ii) the expiration of two years
following the date of any termination of this Agreement pursuant to Article
VIII.

            6.16. Control of the Company's Operations. Nothing contained in
this Agreement shall give SBC or the Company, directly or indirectly,
rights to control or direct the operations of the other prior to the
Effective Time. Prior to the Effective Time, each of SBC and the Company
shall exercise, consistent with the terms and conditions of this Agreement,
complete control and supervision of its operations.


                                ARTICLE VII

                                 Conditions

                    (c) Governmental Consents. The waiting period
applicable to the consummation of the Merger under the HSR Act shall have
expired or been terminated and all material Company Required Consents and
material SBC Required Consents from or with any Governmental Entity shall
have been made or obtained pursuant to a Final Order, free of any
conditions (other than conditions that are not reasonably likely, either
individually or in the aggregate, to have a Regulatory Material Adverse
Effect). For the purposes of this Agreement, "Final Order" means an action
or decision that has been granted as to which (a) 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

time within which it may effect such reconsideration has passed and (d) no
appeal is pending (including other administrative or judicial review) or in
effect and any deadline for filing any such appeal that may be specified by
statute or rule has passed, which in any such case (a), (b), (c) or (d) is

annulling, suspending or modifying such action or decision (in any such
case in a manner which would have a Regulatory Material Adverse Effect
following the Effective Time).

                    (d) Laws and Order. No Governmental Entity of competent
jurisdiction shall have enacted, issued, promulgated, enforced or entered
any Law (whether temporary, preliminary or permanent) that is in effect and
restrains, enjoins or otherwise prohibits consummation of the Merger or the
other transactions contemplated by this Agreement or that is, individually
or in the aggregate with all other such Laws, reasonably likely to have a
Material Adverse Effect on SBC or the Company (collectively, an "Order"),
and no Governmental Entity shall have instituted any proceeding, or, in the
case of a federal Governmental Entity, threatened in writing to institute
any proceeding, seeking any such Order.

                    (e) S-4. The S-4 Registration Statement shall have

effectiveness of the S-4 Registration Statement shall have been issued, and
no proceedings for that purpose shall have been initiated or be threatened
by the SEC.

                    (f) Accountants' Letters. SBC and the Company shall
have received the "comfort" letters described in Section 6.5(b). SBC and

following conditions:

                    (a) Representations and Warranties. The representations 
and warranties of the Company set forth in this Agreement (i) to the extent
qualified by Material Adverse Effect shall be true and correct and (ii) to
the extent not qualified by Material Adverse Effect shall be true and
correct, except that this clause (ii) shall be deemed satisfied so long as
any failures of such representations and warranties to be true and correct,
taken together, do not have a Material Adverse Effect on the Company, in
each case (i) and (ii), as of the Closing Date as though made on and as of
the Closing Date (except to the extent such representations and warranties
speak as of an earlier date), and SBC shall have received a certificate
signed on behalf of the Company by an executive officer of the Company to
such effect.

                    (b) Performance of Obligations of the Company. The
Company shall have performed in all material respects all obligations

shall be required in order to consummate the transactions contemplated by
this Agreement under any Contract to which the Company or any of its
Subsidiaries is a party, except those for which the failure to obtain such
consent or approval, individually or in the aggregate, is not reasonably
likely to have, a Material Adverse Effect on the Company.

                    (d) Tax Opinion. SBC shall have received the opinion of
Sullivan & Cromwell, counsel to SBC, dated the Closing Date, to the effect
that the Merger will be treated for Federal income tax purposes as a
reorganization within the meaning of Section 368(a) of the Code, and that
each of SBC, Merger Sub and the Company will be a party to that
reorganization within the meaning of Section 368(b) of the Code; it being
understood that in rendering such opinion, such counsel shall be entitled
to rely on certain customary representations and assumptions.

waiver by the Company at or prior to the Effective Time of the following
conditions:

and warranties of SBC and Merger Sub set forth in this Agreement (i) to the
extent qualified by Material Adverse Effect shall be true and correct, and
(ii) to the extent not qualified by Material Adverse Effect shall be true
and correct, except that this clause (ii) shall be deemed satisfied so long
as any failures of such representations and warranties to be true and
correct, taken together, do not have a Material Adverse Effect on SBC, in
each case (i) and (ii), as of the Closing Date as though made on and as of
the Closing Date (except to the extent such representations and warranties
speak as of an earlier date), and the Company shall have received a
certificate signed on behalf of SBC by an executive officer of SBC to such
effect.

                    (b) Performance of Obligations of SBC and Merger Sub.
Each of SBC and Merger Sub shall have performed in all material respects
all obligations required to be performed by it under this Agreement at or
prior to the Closing Date, and the Company shall have received a
certificate signed on behalf of SBC and Merger Sub by an executive officer
of SBC to such effect.

                    (c) Tax Opinion. The Company shall have received the
opinion of Skadden, Arps, Slate, Meagher & Flom (Illinois), counsel to the
Company, dated the Closing Date, to the effect that the Merger will be

the Company will be a party to that reorganization within the meaning of
Section 368(b) of the Code; it being understood that in rendering such
opinion, such counsel shall be entitled to rely on certain customary
representations and assumptions.

the Company and SBC, by action of their respective Boards of Directors.

            8.2. Termination by Either SBC or the Company. This Agreement
may be terminated and the Merger may be abandoned at any time prior to the
Effective Time by action of the Board of Directors of either SBC or the
Company if (i) the Merger shall not have been consummated by July 31, 1999
(the "Termination Date"), whether such date is before or after the date of
approval by the stockholders of the Company or SBC; provided, however, that
if SBC or the Company determines that additional time is necessary in
connection with obtaining a SBC Required Consent or a Company Required
Consent from or with any Governmental Entity, the Termination Date may be
extended for up to 60 calendar days at any one time by SBC or the Company
from time to time by written notice to the other party up to a date not

7.1(a) shall not have been obtained at a meeting duly convened therefor or
at any adjournment or postponement thereof, or (iv) any Order permanently
restraining, enjoining or otherwise prohibiting consummation of the Merger
shall become final and non-appealable (whether before or after the adoption
or approval by the stockholders of the Company or SBC, as the case may be);
provided, that the right to terminate this Agreement pursuant to clause (i)
above shall not be available to any party that has breached in any material
respect its obligations under this Agreement in any manner that shall have
proximately contributed to the failure of the Merger to be consummated.

            8.3. Termination by the Company. This Agreement may be
terminated and the Merger may be abandoned at any time prior to the
Effective Time, whether before or after the adoption of this Agreement by
the stockholders of the Company referred to in Section 7.1(a), by action of
the Board of Directors of the Company:

                    (a) if (i) the Board of Directors of the Company approves
entering into a binding written agreement concerning a transaction that
constitutes a Superior Company Proposal and the Company notifies SBC in
writing that the Company desires to enter into such agreement, (ii) SBC
does not make, within ten calendar days after receipt of the Company's
written notification of its desire to enter into a binding agreement for a
Superior Company Proposal, the terms of which are specified in such notice,
an offer that the Board of Directors of the Company believes, in good faith
after consultation with its financial advisors, is at least as favorable,
from a financial point of view, to the stockholders of the Company as the

recommendation to the stockholders of SBC that such stockholders approve the
issuance of SBC Common Stock required to be issued pursuant to Article IV or 
failed to reconfirm such recommendation within fifteen business days after a
written request by the Company to do so; provided that such a request is made
after the Board of Directors of SBC or any SBC Representative shall have taken
any of the actions that would be proscribed by Section 6.2(b) but for the
exception therein allowing certain actions to be taken pursuant to clause
(B) or (C) of the proviso thereof with respect to any bona fide written SBC
Acquisition Proposal that has not been withdrawn or rejected by the Board
of Directors of SBC, (ii) there has been a material breach by SBC or Merger
Sub of any representation, warranty, covenant or agreement contained in
this Agreement which (x) would result in a failure of a condition set forth
in Section 7.3(a) or 7.3(b) and (y) cannot be or is not cured prior to the
Termination Date, or (iii) SBC or any SBC Representative shall take any of
the actions that would be proscribed by Section 6.2(b) but for the
exception therein allowing certain actions to be taken pursuant to clause
(B) or (C) of the proviso thereof (other than any such actions taken

Proposal is received during the 31st through 50th days of the Initial 50
Day Period, in each case if, and only if, SBC receives such SBC Acquisition
Proposal during the Initial 50 Day Period). For purposes of this Agreement,
the "Initial 50 Day Period" shall mean the 50 calendar day period
commencing with the first calendar day after the day on which this
Agreement shall have been filed by SBC or the Company with the SEC as an

consultation with its financial advisors, is at least as favorable, from a
financial point of view, to the stockholders of SBC as the Superior SBC
Proposal, and (iii) SBC prior to such termination pays to the Company in
immediately available funds any fees required to be paid pursuant to
Section 8.5(c). SBC agrees to notify the Company promptly if its desire to
enter into a written agreement referred to in its notification shall change

                    (b) If (i) the Board of Directors of the Company shall 
have withdrawn or adversely modified its approval or recommendation to the
Company's stockholders of this Agreement, or failed to reconfirm such
recommendation within fifteen business days after a written request by SBC
to do so; provided that such a request is made after the Board of Directors
of the Company or any Company Representative shall have taken any of the
actions that would be proscribed by Section 6.2(a) but for the exception
therein allowing certain actions to be taken pursuant to clause (B) or (C)
of the proviso thereof with respect to any bona fide written Company
Acquisition Proposal that has not been withdrawn or rejected by the Board
of Directors of the Company, or (ii) there has been a material breach by

such actions taken pursuant to such clause (B) with respect to any bona
fide written Company Acquisition Proposal (received after the date hereof

Acquisition Proposal by the Company if such Company Acquisition Proposal is
received during the 31st through 50th days of the Initial 50 Day Period, in
each case if, and only if, the Company receives such Company Acquisition
Proposal during the Initial 50 Day Period).

            8.5. Effect of Termination and Abandonment. (a) In the event of
termination of this Agreement and the abandonment of the Merger pursuant to
this Article VIII, this Agreement (other than as set forth in Section 9.1)
shall become void and of no effect with no liability on the part of any
party hereto (or of any of its directors, officers, employees, agents,
legal or financial advisors or other representatives); provided, however,
no such termination shall relieve any party hereto from any liability for
damages resulting from any willful and intentional breach of this Agreement
(to the extent any such damages exceed any Termination Fee that may have
been paid pursuant to Section 8.5(b) or 8.5(c)) or from any obligation to
pay, if applicable, the Termination Fee pursuant to Section 8.5(b) or
8.5(c).

                    (b) In the event that (i) a bona fide Company Acquisition
Proposal shall have been made to the Company and made known to stockholders
generally or have been made directly to stockholders generally or any
Person shall have publicly announced an intention (whether or not
conditional) to make a bona fide Company Acquisition Proposal and such
Company Acquisition Proposal or announced intention shall not have been
withdrawn prior to the Company's Stockholders Meeting and thereafter this
Agreement is terminated by either SBC or the Company pursuant to Section
8.2(ii) and within nine months after such termination the Company shall
have entered into an agreement to consummate a transaction that would
constitute a Company Acquisition Proposal if it were the subject of a
proposal, or (ii) this Agreement is terminated (x) by the Company pursuant
to Section 8.3(a) or (y) by SBC pursuant to Section 8.4(b)(i), (b)(ii)
(solely with respect to a willful and intentional breach) or (b)(iii), then
the Company shall promptly, but in no event later than two days after the
date of such termination (except as otherwise provided in Section 8.3(a)),
or, in the case of termination pursuant to Section 8.2(ii), two days after
the relevant agreement is entered into, pay SBC a fee equal to $1.2 billion
(the "Termination Fee"), which amount shall be exclusive of any expenses to
be paid pursuant to Section 6.11, payable by wire transfer of same day
funds. The Company acknowledges that the agreements contained in this
Section 8.5(b) are an integral part of the transactions contemplated by
this Agreement, and that, without these agreements, SBC and Merger Sub
would not enter into this Agreement; accordingly, if the Company fails to
pay promptly the amount due pursuant to this Section 8.5(b), and, in order
to obtain such payment, SBC or Merger Sub commences a suit which results in
a judgment against the Company for the fee set forth in this paragraph (b),
the Company shall pay to SBC or Merger Sub its costs and expenses
(including attorneys' fees) in connection with such suit, together with
interest on the amount of the fee at the prime rate of Citibank N.A. in
effect on the date such payment was required to be made.

                    (c) In the event that (i) a bona fide SBC Acquisition 
Proposal shall have been made to SBC and made known to stockholders generally 
or shall have been made directly to stockholders generally or any Person shall
have publicly announced an intention (whether or not conditional) to make a
bona fide SBC Acquisition Proposal and such SBC Acquisition Proposal or
announced intention shall not have been withdrawn prior to the SBC
Stockholder Meeting and thereafter this Agreement is terminated by the
Company or SBC pursuant to Section 8.2(iii) and within nine months after
such termination SBC shall have entered into an agreement to consummate a
transaction that would constitute a SBC Acquisition Proposal if it were the
subject of a proposal, or (ii) this Agreement is terminated (x) by SBC
pursuant to Section 8.4(a) or (y) by the Company pursuant to Section
8.3(b)(i), (b)(ii) (solely with respect to a willful and intentional
breach) or (b)(iii), then SBC shall promptly, but in no event later than
two days after the date of such termination (except as otherwise provided
in Section 8.4(a)), or, in the case of a termination pursuant to Section
8.2(iii), two (2) days after the relevant agreement is entered into, pay
the Company a fee equal to the Termination Fee, which amount shall be
exclusive of any expenses to be paid pursuant to Section 6.11, payable by
wire transfer of same day funds. SBC acknowledges that the agreements
contained in this Section 8.5(c) are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, the
Company would not enter into this Agreement; accordingly, if SBC fails to
pay promptly the amount due pursuant to this Section 8.5(c), and, in order
to obtain such payment, the Company commences a suit which results in a
judgment against SBC for the fee set forth in this paragraph (c), SBC shall
pay to the Company its costs and expenses (including attorneys' fees) in
connection with such suit, together with interest on the amount of the fee
at the prime rate of Citibank N.A. in effect on the date such payment was
required to be made.

                     FORM OF COMPANY AFFILIATE'S LETTER


_______, 1998




SBC Communications Inc.
175 E. Houston
San Antonio, TX   78205

Ladies and Gentlemen:

The undersigned is a holder of shares of Common Stock, $1.00 par value per
share ("Company Common Stock"), of Ameritech Corporation, a Delaware
corporation (the "Company"). Pursuant to the terms of that certain
Agreement and Plan of Merger, dated as of May 10, 1998, among the Company,
SBC Communications Inc., a Delaware corporation ("SBC"), and SBC
(Delaware), Inc., a Delaware corporation and a whollyowned subsidiary of
SBC ("Merger Sub"), Merger Sub will be merged with and into the Company and
the Company will become a wholly owned subsidiary of SBC (the "Merger"). In
connection with the Merger, the undersigned, as a holder of Company Common
Stock, will be entitled to receive Common Stock, par value $1.00 per share,
of SBC (the "Securities") in exchange for the shares of Company Common
Stock held by the undersigned at the effective time of the Merger.

The undersigned acknowledges that the undersigned may be deemed an
"affiliate" of the Company within the meaning of Rule 145 ("Rule 145")
promulgated under the Securities Act of 1933, as amended (the "Act"),
and/or as such term is used in and for purposes of Accounting Series
Release Nos. 130 and 135, as amended, of the Securities and Exchange
Commission (the "Commission"), although nothing contained herein shall be
construed as an admission of such status.

If in fact the undersigned were an affiliate of the Company under the Act,
the undersigned's ability to sell, assign or transfer any Securities
received by the undersigned in exchange for any shares of Company Common
Stock pursuant to the Merger may be restricted unless such sale, assignment
or transfer is registered under the Act or an exemption from such
registration is available. The undersigned understands that such exemptions
are limited and the undersigned has obtained advice of counsel as to the
nature and conditions of such exemptions, including information with
respect to the applicability to the sale of such Securities of Rules 144
and 145(d) promulgated under the Act.

The undersigned hereby represents to and covenants with SBC that it will
not sell, assign or transfer any Securities received by the undersigned in
exchange for shares of Company Common Stock pursuant to the Merger except
(i) pursuant to an effective registration statement under the Act, (ii) by
a sale made in conformity with the volume and other limitations of Rule 145
(and otherwise in accordance with Rule 144 under the Act, if the
undersigned is an affiliate of SBC and if so required at the time) or (iii)
in a transaction which, in the opinion of independent counsel reasonably
satisfactory to the Company or as described in a "noaction" or interpretive
letter from the Staff of the Commission reasonably satisfactory to SBC, is
not required to be registered under the Act.

The undersigned understands that SBC is under no obligation to register the
sale, assignment, transfer or other disposition of the Securities by the
undersigned or on behalf of the undersigned under the Act or to take any
other action necessary in order to make compliance with an exemption from
such registration available solely as a result of the Merger.

In the event of a sale of Securities pursuant to Rule 145, the undersigned
will supply SBC with evidence of compliance with such Rule, in the form of
customary seller's and broker's Rule 145 representation letters or as SBC
may otherwise reasonably request. The undersigned understands that SBC may
instruct its transfer agent to withhold the transfer of any Securities
disposed of by the undersigned in a manner inconsistent with this letter.

The undersigned acknowledges and agrees that appropriate legends will be
placed on certificates representing Securities received by the undersigned
in the Merger or held by a transferee thereof, which legends will be
removed (i) by delivery of substitute certificates upon receipt of a letter
from the staff of the Commission, or an opinion of counsel in form and
substance reasonably satisfactory to SBC, to the effect that such legends
are no longer required for the purposes of the Act and the rules and
regulations of the Commission promulgated thereunder, (ii) in the event of
a sale of the Securities which has been registered under the Act or made in
conformity with the provisions of Rule 145.

The undersigned further represents to and covenants with SBC that (i) the
undersigned will not, during the 30 days prior to the effective time of the
Merger sell, transfer or otherwise dispose of, or reduce any risk relative
to, any securities of the Company or SBC, and (ii) the undersigned will
not, after the effective time of the Merger, sell, transfer or otherwise
dispose of, or reduce any risk relative to, the Securities, whether
received by the undersigned in the Merger or otherwise, until after such
time as financial results covering at least 30 days of postMerger
operations of SBC (including the combined operations of the Company and
SBC) have been published by SBC in the form of a quarterly earnings report,
an effective registration statement filed with the Commission, a report to
the Commission on Form 10K, 10Q or 8K, or any other public filing or
announcement which includes such results of operations, except in the cases
of clauses (i) and (ii) of this paragraph to the extent permitted by, and
in accordance with, SEC Accounting Series Release 135 and SEC Staff
Accounting Bulletins 65 and 76 if and to the extent that such release and
bulletins remain in full force and effect at the relevant time.

I further understand and agree that this letter agreement shall apply to
all shares of Company Common Stock and Securities that I am deemed to
beneficially own pursuant to applicable federal securities law.

The undersigned acknowledges that it has carefully reviewed this letter and
understands the requirements hereof and the limitations imposed upon the
distribution, sale, transfer or other disposition of Securities.

Sincerely,

                                NEWS RELEASE


              SBC COMMUNICATIONS AND AMERITECH TO MERGE

               CREATES NATIONAL AND GLOBAL COMPETITOR:
              A NEW KIND OF TELECOMMUNICATIONS COMPANY


            SAN ANTONIO, TEXAS (May 11, 1998)--SBC Communications Inc.
(NYSE: SBC) and Ameritech Corporation (NYSE: AIT) have agreed to a $62
billion, industry-transforming merger that will create a new type of
telecommunications company with a "national-local" focus combined with
national and international service capabilities. The company will have the
assets, scope and strategies to compete against incumbent local
telecommunications companies, competitive local exchange carriers, long
distance companies and global competitors. 

            "The merger will enable the new SBC to accelerate and expand
telecommunications competition by entering 30 U.S. markets outside its
traditional 13-state local region (see attached list) so that the combined
company will serve customers in all the top 50 markets in the nation. In
addition, the new company will build on its growing international presence
to serve a worldwide market. We will provide a competitive, integrated mix
of local, long distance, Internet and high-speed data services providing
more choices, new and improved services, more competitive prices and more
convenience for millions of consumers, giving us the opportunity to create
significant value for our shareowners," said Edward E. Whitacre Jr.,
chairman and chief executive officer of SBC.

            "This transaction will allow us to implement a 'national-local'
strategy in which we will offer local services across the country in
combination with major national and international operations," Whitacre
added. "It will transform us from a regional company to a new kind of
company that uses its premiere networks to focus on 'national-local' and
global markets. We will then be positioned to compete head-to-head with
incumbent local telephone companies, competitive local exchange carriers
(CLECs), data networks, long distance carriers and global competitors." 

            "We know we have the people, resources and the ability to make
our new company an unqualified success for our customers, our employees,
and our shareholders. We leap forward in terms of our ability to invest in
new technology and become a leading player in the global marketplace," said
Richard C. Notebaert, chairman and chief executive officer of Ameritech.

            Ameritech shareholders will receive a fixed exchange ratio of
1.316 SBC shares for each share of Ameritech. Based upon closing prices as
of May 8, after adjusting for the exchange ratio, the combined companies'
value is $146 billion. The transaction will be a tax free, stock-for-stock
exchange and will be accounted for as a pooling of interests. The combined
company will be called SBC and will be approximately 56% owned by SBC's
existing shareowners and 44% by Ameritech's existing shareowners (ownership
percentages are prior to SBC completing its merger with SNET).

            "The Telecommunications Act of 1996 helped open the door to a
period of rapid change in the telecommunications industry. But so far, it
has not created the level of competition that many expected," said
Notebaert.

            "This merger is critical because it transforms us into a
company that has the size, scope and incentive to make the promise of the
Act a reality. This new company will be in the best position to serve our
customers in the evolving marketplace. We expect to see, in the next few
years, the emergence of integrated national and international operators.
Successful carriers will either be part of this group or more narrowly
focused niche players. Our combined company intends to be one of the
successful global operators," said Notebaert.

            "This merger should be viewed as a welcomed development by
regulators," said Whitacre. "If they are looking for a truly potent way to
jump start competition, then approving this merger should be a clear
decision."

            "We are going to take advantage of the best employee team, the
best customer service, and the best technology around," said Whitacre.

            The executives noted several benefits of the merger at the
announcement:

      o     Consumers and businesses, large and small, in markets such as
            New York, Baltimore/Washington, Boston, Atlanta, Denver,
            Philadelphia, Miami, Phoenix and Seattle will benefit from a
            new major alternative for all their telecommunications needs,
            one brought to them by a company with local exchange
            experience, marketing experience and advanced technology
            products. The new company will pursue multiple market entry
            strategies that include building, acquiring and partnering.

      o     Customers in the 13-state region already served by SBC and
            Ameritech-which include half of the Fortune 500 companies-will
            enjoy the best and most competitively priced product offerings
            and services of each company.

      o     The new company will be able to serve customers in all the top
            50 U.S. markets, increasing the potential customer base to 180
            million people.

      o     Local competition in the 13-state region will be advanced as
            SBC and Ameritech, the recognized leaders in interconnection
            technology, create a uniform standard of technical excellence
            for operational support systems available to competitors. The
            new company will deliver products and services more efficiently
            to retail and wholesale customers, enhancing competition in the
            13-state region.

      o     The merged company's combined international assets, which include
            operations in 19 countries in Europe, Asia, Africa, North
            America and South America, coupled with its integrated
            services, will allow it to follow customers wherever they go.

            The combination will also result in significant opportunities
for revenue growth, technology development, cost synergies and other
benefits. "We expect to optimize costs through increased economies of scale
and scope, the elimination of duplicated expenditures and the adoption of
best practices in cost control," said Whitacre. "We expect to grow revenues
more rapidly than would have been possible independently both in our
existing service areas and in new markets. These synergies can be used to
integrate our two companies, improve our operations, benefit our customers
and fund expansion.

            "The experience and knowledge we have gained from the very
successful integration of Pacific Telesis makes us very confident about our
ability to realize the potential financial and strategic benefits of the
combination with Ameritech. Going forward the transaction and strategy
announced today will diversify our sources of earnings and establish a
platform for sustainable future growth," Whitacre continued.

            The anticipated cost synergies resulting from the merger will
not result in any net job reductions in the combined company. As a result
of growth in existing lines of business, out-of-region expansion and new
opportunities in data, long distance and other new services, the total
number of employees is expected to rise over the next few years.

            In fact, SBC made a commitment to Ameritech that employment
levels in the five-state region will not be reduced due to the transaction,
as well as to:

      o     maintain Ameritech's headquarters in Chicago and its state
            headquarters in its traditional states of Illinois, Indiana,
            Michigan, Ohio and Wisconsin;

      o     continue to use the Ameritech name in each of its operating
            states;

      o     continue to support economic development and education in
            Ameritech's region consistent with its well-established
            commitment; and

      o     continue Ameritech's historic levels of charitable
            contributions and community activities.

            After the transaction is completed, Whitacre will remain as
chairman and chief executive officer of SBC. Notebaert will remain as
chairman and chief executive officer of Ameritech. Upon closing of the
merger, SBC's board of directors will be expanded to include Notebaert and
four other current Ameritech directors.

            The merger is subject to shareholder and regulatory approvals.
Since federal law prohibits ownership of overlapping wireless licenses, the
companies will divest certain cellular properties. "Given the size and
significance of the transaction we expect close scrutiny but ultimate
approval from regulatory authorities," said Whitacre. "Obviously, given the
paradigm shifting potential of this merger and the rapid changes in our
business, the sooner we can deliver the benefits of this merger to
consumers, the better. We recognize that we need the support of regulators
for this transaction to be approved. We are committed to listening to any
concerns they might raise, and to working with them to promptly resolve any
issues. We anticipate the transaction closing within a year," he continued.

            Salomon Smith Barney acted as the financial advisor to SBC
Communications on the transaction. Goldman Sachs & Co. advised Ameritech.
