Dear Shareholder:
 
    We invite you to attend the Special Meeting of Shareholders of The Woodbury
Telephone Company ("WTC") to be held on April 2, 1997 at 10:30 a.m. local time
at the Southbury Hilton, 1284 Strongtown Road (Exit 16, Interstate 84),
Southbury, Connecticut 06488.
 
    At the Special Meeting, shareholders of WTC will vote upon the proposal to
approve the Amended and Restated Agreement and Plan of Merger dated as of
December 6, 1996 (the "Merger Agreement"), among Southern New England
Telecommunications Corporation ("SNET"), SNET Acquisition Subsidiary, Inc., a
wholly-owned subsidiary of SNET ("SAS"), and WTC. Pursuant to the Merger
Agreement, SAS will merge into WTC and WTC will become a wholly-owned subsidiary
of SNET, and each share of WTC common stock held by WTC shareholders (excluding
shares of WTC common stock held by SNET, which owns 36.5 percent of WTC) will be
converted into the right to receive a number of publicly traded and listed
shares of SNET common stock having a value equal to $43.00, subject to
adjustment as described in the accompanying Prospectus/Proxy Statement. The
transaction is intended to be generally free of federal income tax consequences
to WTC shareholders.
 
    Consummation of the merger is subject to a number of conditions, including
approval by WTC shareholders and approval by governmental regulatory
authorities.
 
    Please review carefully the accompanying Prospectus/Proxy Statement, which
describes the proposed merger and to which is attached a copy of the Merger
Agreement. Furthermore, please review the financial and other information set
forth in the documents described under "AVAILABLE INFORMATION" in the
Prospectus/Proxy Statement with respect to both SNET and WTC.
 
    WTC'S BOARD OF DIRECTORS HAS APPROVED THE PROPOSED MERGER AND RECOMMENDS
THAT SHAREHOLDERS APPROVE THE MERGER AGREEMENT BY VOTING "FOR" ON THE ENCLOSED
PROXY CARD. A FAILURE TO VOTE, EITHER BY NOT RETURNING THE ENCLOSED PROXY CARD
OR BY CHECKING THE "ABSTAIN" BOX THEREON, WILL HAVE THE SAME EFFECT AS A VOTE
"AGAINST" APPROVAL OF THE MERGER AGREEMENT.
 
    Please complete the enclosed Proxy Card, and sign, date and mail it promptly
in the enclosed postage paid return envelope. Even if you intend to attend the
Special Meeting, I urge you to return the Proxy Card, duly completed, signed and
dated.
 
    Because of the Special Meeting, we have determined to defer our Annual
Meeting of Shareholders until a later date, if required.
 
                                          Very truly yours,

Dear Shareholder:                                                 March 11, 1997
    
 
    NOTICE IS HEREBY GIVEN that a Special Meeting of Shareholders of The

        To consider and vote upon a proposal to approve the Amended and Restated
    Agreement and Plan of Merger, dated as of December 6, 1996 (the "Merger
    Agreement"), among The Woodbury Telephone Company ("WTC"), Southern New

    merge with and into WTC (the "Merger") and each outstanding share of WTC's

    the right to receive a number of shares of common stock, par value $1.00 per
    share, together with SNET Rights (as defined in the accompanying
    Prospectus/Proxy Statement) attached thereto ("SNET Common Stock") equal to
    the product of one share of SNET Common Stock times a fraction the numerator
    of which is $43.00 and the denominator of which is equal to the average of
    the closing prices (the "Average Closing Price") of one share of SNET Common
    Stock as reported on the New York Stock Exchange for the ten trading days
    ending on the fifth business day prior to the effective time of the Merger
    (the "Merger Consideration"); provided that if the Average Closing Price is
    less than $30.00, then the Merger Consideration shall be determined in
    accordance with the foregoing formula based on a deemed Average Closing
    Price of $30.00 and WTC shall have the option to consummate the Merger based
    on such deemed Average Closing Price and, if WTC does not opt to do so, then
    SNET shall have the option to terminate the Merger; and if the Average
    Closing Price is more than $49.00, then the Merger Consideration shall be
    determined in accordance with the foregoing formula based on a deemed

    the Merger based on such deemed Average Closing Price and, if SNET does not
    opt to do so, then WTC shall have the option to terminate the Merger.
 
    A copy of the Merger Agreement is set forth in ANNEX A to the accompanying
Prospectus/Proxy Statement.
 
    The Board of Directors of WTC has fixed February 14, 1997 as the record date
for the determination of shareholders entitled to notice of and to vote at the
Special Meeting and, accordingly, only holders of record of WTC Common Stock at
the close of business on that date will be entitled to notice of and to vote at

Special Meeting of the holders of at least (a) 80 percent of all of the
outstanding shares of WTC Common Stock and (b) two-thirds of the outstanding
shares of WTC Common Stock not held by SNET and its affiliates and associates.
 
    Each holder of WTC Common Stock who is entitled to vote on approval of the
Merger Agreement has the right to object to the Merger and to be paid the fair
value of such holder's WTC Common Stock in cash if the Merger Agreement is
approved and the Merger is consummated. The right of any such holder of WTC
Common Stock to receive such payment is contingent upon strict compliance with
the requirements set forth in the applicable provisions of the Connecticut
Business Corporation Act, the full text of which provisions is set forth in
ANNEX C to the accompanying Prospectus/Proxy Statement and a summary of which is
set forth under "THE MERGER--Dissenters' Rights."

PARTIES TO THE MERGER
 
   
<TABLE>
<S>                   <C>
       SNET:          SNET is a Connecticut-based company reaching beyond its traditional
                      borders to offer wireline, wireless and information and entertainment
                      services, including local, national and international calling; mobile
                      communications; and publishing, information and advertising. SNET is
                      building I-SNET-SM-, a statewide information superhighway that brings
                      to customers a full array of information, communications and
                      entertainment services. The principal executive offices of SNET are at
                      227 Church Street, New Haven, Connecticut 06510. Its telephone number
                      is (203) 771-5200.
 
       SAS:           SAS is a wholly-owned subsidiary of SNET created solely for the
                      purpose of effecting the Merger. The principal executive offices of
                      SAS are at 227 Church Street, New Haven, Connecticut 06510. Its
                      telephone number is (203) 771-5200.
 
       WTC:           WTC provides local exchange telephone services, intrastate toll
                      services and access to long distance telephone services (both
                      intrastate and interstate). WTC also sells telephone equipment. WTC is
                      the primary provider of local exchange service in the major portions
                      of the Towns of Woodbury, Southbury and Bethlehem, Connecticut, and
                      also provides local exchange service to small portions of the Towns of
                      Oxford and Roxbury, Connecticut. The principal executive offices of
                      WTC are at 299 Main Street South, Woodbury, Connecticut 06798. Its
                      telephone number is (203) 263-2121.
</TABLE>
    
 
SPECIAL MEETING; RECORD DATE
 
    The Special Meeting is scheduled to be held on April 2, 1997 at 10:30 a.m.,
at the Southbury Hilton, 1284 Strongtown Road (Exit 16, Interstate 84),
Southbury, Connecticut 06488. At the Special Meeting, shareholders will consider
and vote upon a proposal to approve the Merger Agreement and the transactions
contemplated thereby.
 
    The WTC Board has fixed February 14, 1997 as the record date for determining
shareholders entitled to notice of and to vote at the Special Meeting (the
"Record Date"). As of such date, there were 769,107 shares of WTC Common Stock
outstanding, of which 280,645 shares (constituting 36.5 percent) are owned of
record and beneficially by SNET (the "SNET Shareholdings").
 
THE MERGER
 
    Subject to the terms and conditions of the Merger Agreement, SAS will merge
with and into WTC, and thereafter WTC will be a wholly-owned subsidiary of SNET.
Upon consummation of the Merger, each
 
                                       6
<PAGE>
outstanding share of WTC Common Stock (excluding any Dissenting Shares and any
SNET Shareholdings (the SNET Shareholdings, together with the Dissenting Shares,
herein the "Excluded Shares")) will be converted into the right to receive a
number of shares of SNET Common Stock equal to $43.00, as may be adjusted
pursuant to the Merger Agreement. (See "THE MERGER--General;--Exchange of WTC
Certificates;--Dissenters' Rights"; "DESCRIPTION OF SNET CAPITAL STOCK" and
"MATERIAL DIFFERENCES BETWEEN THE RIGHTS OF HOLDERS OF SNET COMMON STOCK AND WTC
COMMON STOCK.")
 
VOTE REQUIRED
 
    Approval of the Merger Agreement requires the affirmative votes of the
holders of at least (a) 80 percent of all of the outstanding shares of WTC
Common Stock and (b) two-thirds of the outstanding shares of WTC Common Stock
not held by SNET and its affiliates and associates.
 
    The directors and executive officers of WTC (including certain of their
related interests) beneficially owned, as of the Record Date, and are entitled
to vote at the Special Meeting, 10,558 shares of WTC Common Stock, which
represents 1.37 percent of the outstanding shares of WTC Common Stock entitled
to be voted at the Special Meeting. The directors have informed WTC that they
intend to vote all of their shares of WTC Common Stock in favor of approval of
the Merger Agreement. SNET has informed the WTC Board that it intends to vote
the SNET Shareholdings in favor of approval of the Merger Agreement. (See "THE
SPECIAL MEETING--Record Date; Vote Required; Revocation of Proxies.")
 
    A FAILURE TO VOTE, EITHER BY NOT RETURNING THE ENCLOSED PROXY OR BY CHECKING
THE "ABSTAIN" BOX THEREON, WILL HAVE THE SAME EFFECT AS A VOTE "AGAINST"
APPROVAL OF THE MERGER AGREEMENT.
 
EFFECTIVE TIME
 
    Subject to the conditions to the obligations of the parties to effect the
Merger set forth in the Merger Agreement, the Merger will become effective when
the certificates required under applicable law are filed with the Connecticut
Secretary of State on the date of the closing of transactions or on such other
date as the parties to the Merger Agreement shall agree. The closing of
transactions is contemplated to occur within ten days following the receipt of
all regulatory approvals. Subject to the foregoing, it is currently anticipated
that the Merger will be consummated in the second or third quarter of 1997. If
the Merger is consummated in either of such quarters, or in any other quarter,
WTC shareholders should not assume or expect that the Effective Time will
precede the record date for the dividend on SNET Common Stock for that quarter,
so as to enable such shareholders to receive such dividend. (See "THE MERGER--
Exchange of WTC Certificates" and "--Conditions to Consummation; Termination.")
 
RECOMMENDATION OF THE WTC BOARD
 
    The terms of the Merger were arrived at as the result of arm's-length
negotiations between representatives of SNET and WTC.
 
    The WTC Board has adopted the Merger Agreement by unanimous vote, believes
the Merger is fair and in the best interests of WTC and its shareholders and
recommends its approval by WTC shareholders. (Such unanimous vote did not
include the vote of Michael Phelan, SNET's designee on the WTC Board, who
abstained.) The decision of the WTC Board to approve the Merger Agreement and
the Merger and to recommend the approval thereof to the shareholders of WTC was
based on a number of considerations. (See "THE MERGER--Background and Reasons;
WTC.")
 
OPINION OF FINANCIAL ADVISOR
 
    McDonald & Company Securities, Inc. ("McDonald") has advised the WTC Board
that, in its opinion, the Merger Consideration to be received by WTC
shareholders in the Merger is fair, from a
 
                                       7
<PAGE>
financial point of view, to the holders of WTC Common Stock. The full text of
the McDonald opinion, which describes the procedures followed, assumptions made,
limitations on the review undertaken and other matters in connection with
rendering such opinion, is set forth in ANNEX B to this Prospectus/Proxy
Statement and should be read in its entirety by WTC shareholders. (See "THE
MERGER--Opinion of Financial Advisor.")
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    Certain members of WTC's management and the WTC Board of Directors may be
deemed to have interests in the Merger in addition to their interests as
shareholders of WTC generally. These include, among other things, provisions in
the Merger Agreement relating to indemnification, directors' and officers'
liability insurance, and certain other benefits as summarized below. In
addition, WTC is obligated, and will continue to be obligated after the Merger,
to continue to pay deferred compensation to J. Garry Mitchell, Chairman of the
Board and a director of WTC; and Donald E. Porter, President and a director of
WTC, may be entitled to other payments from WTC if he is terminated without
cause within 24 months following a Change of Control (as defined). SNET
designates a director to sit on the WTC Board, and such designee has not
participated in WTC Board discussions concerning the Merger or votes of the WTC
Board regarding the Merger. (See "THE MERGER--Interests of Certain Persons.")
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    Among other things, consummation of the Merger is conditioned upon receipt
by WTC of an opinion of Carmody & Torrance, counsel for WTC, dated as of the
Effective Time to the effect that no gain or loss will be recognized for federal
income tax purposes by shareholders of WTC who receive SNET Common Stock in
exchange for their shares of WTC Common Stock, except that gain or loss may be
recognized as to cash received in lieu of fractional share interests, or in the
case of any holders of WTC Common Stock who perfect their dissenters' rights,
cash received upon exercise of such rights. (See "THE MERGER-- Certain Federal
Income Tax Consequences" and "--Dissenters' Rights.")
 
    BECAUSE CERTAIN TAX CONSEQUENCES MAY VARY DEPENDING UPON THE PARTICULAR
CIRCUMSTANCES OF EACH SHAREHOLDER, IT IS RECOMMENDED THAT SHAREHOLDERS CONSULT
THEIR TAX ADVISORS CONCERNING THE FEDERAL (AND ANY STATE AND LOCAL) TAX
CONSEQUENCES OF THE MERGER IN THEIR PARTICULAR CIRCUMSTANCES.
 
DISSENTERS' RIGHTS
 
    Holders of WTC Common Stock entitled to vote on approval of the Merger
Agreement have the right to object to the Merger, and upon consummation of the
Merger and the satisfaction of certain specified procedures, to be paid the fair
value of such holders' shares of WTC Common Stock in cash, in accordance with
the applicable provisions of the Connecticut Business Corporation Act ("CBCA").
The procedures to be followed by objecting shareholders are summarized under
"THE MERGER--Dissenters' Rights." A copy of the applicable provisions of the
CBCA is set forth in ANNEX C to this Prospectus/Proxy Statement. FAILURE TO
FOLLOW SUCH PROVISIONS PRECISELY MAY RESULT IN LOSS OF SUCH DISSENTERS' RIGHTS.
 
    In general, any objecting shareholder who perfects such holder's statutory
right to be paid in cash the fair value of such holder's WTC Common Stock will
recognize gain or loss for federal income tax purposes upon receipt of such
cash. (See "THE MERGER--Certain Federal Income Tax Consequences.")
 
RESALE OF SNET COMMON STOCK
 
    The shares of SNET Common Stock issued in the Merger to holders of WTC
Common Stock who are not "affiliates" (generally including directors, certain
executive officers and ten percent or more shareholders) of WTC may be resold by
them under the Securities Act. The shares of SNET Common Stock issued
 
                                       8
<PAGE>
to those holders of WTC Common Stock who may be deemed to be affiliates of WTC
may be resold by them only in transactions permitted by the resale provisions of
Rule 145 under the Securities Act. It is a condition to consummation of the
Merger that each holder of WTC Common Stock who is deemed by WTC to be an
affiliate has entered into an agreement with SNET providing, among other things,
that such affiliate will not transfer any SNET Common Stock received by such
affiliate in the Merger except in compliance with the Securities Act. (See
"RESALE OF SNET COMMON STOCK.")
 
CONDITIONS TO THE MERGER
 
    The obligations of the parties under the Merger Agreement to consummate the
Merger are subject to a number of conditions, certain of which may be material.
(See "THE MERGER--Conditions to Consummation; Termination.")
 
   
    Consummation of the Merger is subject to the approval of the Connecticut
Department of Public Utility Control ("DPUC") and further subject to the
expiration or early termination of all applicable waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"). The Merger will not proceed in the absence of requisite regulatory
approvals. (See "THE MERGER --Regulatory Approvals.")
    
 
ACCOUNTING TREATMENT
 
   
    It is intended that the Merger will be accounted for as a purchase under
generally accepted accounting principles. (See "THE MERGER--Accounting
Treatment.")
    
 
CERTAIN DIFFERENCES IN THE RIGHTS OF WTC AND SNET SHAREHOLDERS
 
    The rights of shareholders of WTC are currently determined by reference to
the CBCA and by WTC's Certificate of Organization, as amended (the "WTC
Certificate") and bylaws, as amended (the "WTC Bylaws"). At the Effective Time,
shareholders of WTC will become shareholders of SNET, and their rights as
shareholders of SNET will be determined by reference to the CBCA and by SNET's
Certificate of Incorporation, as amended (the "SNET Certificate"), and bylaws,
as amended (the "SNET Bylaws"). (See "DESCRIPTION OF SNET CAPITAL STOCK" and
"MATERIAL DIFFERENCES BETWEEN THE RIGHTS OF HOLDERS OF SNET COMMON STOCK AND WTC
COMMON STOCK.")
 
COMPARISON OF CERTAIN PER SHARE DATA
 
    The following tables set forth for the SNET Common Stock and the WTC Common
Stock as of September 30, 1996 and December 31, 1995 certain historical, pro
forma and equivalent pro forma per share financial information for the nine
month period and the year then ended, respectively. All such information is
presented on a per share basis. The pro forma amounts included below are based
on the purchase method of accounting. The equivalent pro forma information for

share of WTC Common Stock based on the calculation contained in the Merger
Agreement using the closing price of SNET Common Stock on February 28, 1997 of
$36.25 as reported on the NYSE. The market value per share data is presented as
of October 21, 1996, the date preceding the public announcement of the Merger.

                              RECENT DEVELOPMENTS
 
   
    Shortly following the joint public announcement on October 22, 1996 by SNET
and WTC of the agreement in principle to proceed with the Merger, the management
of WTC became aware, in the course of its normal review of trading activity in
WTC Common Stock, of certain unexplained trading activity. Some of such activity
closely preceded the October 22, 1996 public announcement. The last reported
sale price of WTC Common Stock on October 21, 1996 (the last trading day
preceding the public announcement) was $26.875. On October 23, 1996, the first
trading day following the public announcement, such price was $38.00.
    
 
    WTC, on a totally voluntary basis, promptly informed the Commission of such
unexplained activity and, in response to the Commission's request, provided
certain written information to the Commission on November 12, 1996 and
thereafter.
 
    SNET has informed WTC that the Commission has requested SNET to provide
certain information, and in response thereto, SNET informed WTC that it has
complied.
 
    WTC has been informed by the Commission that its investigation is not
expected to be concluded by the date of the Special Meeting.
 
                              THE SPECIAL MEETING
 
GENERAL
 
    This Prospectus/Proxy Statement is being furnished by WTC to its
shareholders as a Proxy Statement in connection with the solicitation of proxies
by the WTC Board for use at the Special Meeting to be held on April 2, 1997 and
any adjournments or postponements thereof, to consider and vote upon a proposal
to approve the Merger Agreement and the transactions contemplated thereby.
 
    Directors, officers and employees of WTC and SNET may solicit proxies from
WTC shareholders, either personally or by telephone, telegraph or other forms of
communication. Such persons will receive no additional compensation for such
services. All expenses associated with the solicitation of proxies in the form
enclosed will be borne by the party incurring the same, except for printing
expenses, which will be shared equally by SNET and WTC.
 
    THE WTC BOARD VOTING ON THE MERGER (THE DIRECTOR AFFILIATED WITH SNET HAVING
ABSTAINED) HAS UNANIMOUSLY ADOPTED THE MERGER AGREEMENT, BELIEVES THE MERGER
AGREEMENT IS IN THE BEST INTERESTS OF WTC AND ITS SHAREHOLDERS AND IS FAIR TO
THE SHAREHOLDERS, AND RECOMMENDS APPROVAL OF THE MERGER AGREEMENT BY WTC
STOCKHOLDERS. (See "THE MERGER--Background and Reasons; WTC.")
 
RECORD DATE; VOTE REQUIRED; REVOCATION OF PROXIES
 
    The WTC Board has fixed February 14, 1997, as the Record Date for
determining shareholders entitled to notice of and to vote at the Special
Meeting and, accordingly, only holders of WTC Common Stock of record at the
close of business on that day are entitled to notice of and to vote at the
Special Meeting. The number of shares of WTC Common Stock outstanding on the
Record Date was 769,107, of which 280,645 shares constitute the SNET
Shareholdings. Each share of WTC Common Stock is entitled to one vote. The
presence, in person or by proxy, of at least a majority of the total number of
outstanding shares is necessary to constitute a quorum at the Special Meeting.
Abstentions and broker non-votes (i.e., proxies from brokers or nominees
indicating that such persons have not received instructions from the beneficial
owners or other persons as to certain proposals on which such beneficial owners
or persons are entitled to vote their shares but with respect to which the
brokers or nominees have no discretionary power to vote without such
instruction) will be treated as shares present at the Special Meeting for
purposes of determining the presence of a quorum. Approval of the Merger
Agreement requires the affirmative votes of the holders of at least (a) 80
percent of all of the outstanding shares of WTC Common Stock and
 
                                       12
<PAGE>
(b) two-thirds of the outstanding shares of WTC Common Stock not held by SNET
and its affiliates and associates. Therefore, abstentions and broker non-votes
will have the same effect as votes against approval of the Merger Agreement.
 
    The directors and executive officers of WTC beneficially owned, as of the
Record Date, and are entitled to vote at the Special Meeting, 10,558 shares of
WTC Common Stock, which represents 1.37 percent of the outstanding shares of WTC
Common Stock entitled to be voted at the Special Meeting. The directors have
informed WTC that they intend to vote all of their shares of WTC Common Stock in
favor of approval of the Merger Agreement. SNET has informed the WTC Board that
it intends to vote all of its shares of WTC Common Stock, constituting the SNET
Shareholdings, in favor of approval of the Merger Agreement.
 
    After having been submitted, the enclosed proxy may be revoked by the person
giving it, at any time before it is exercised, by: (i) submitting written notice
of revocation of such proxy to the Secretary of WTC; (ii) submitting a proxy
having a later date; or (iii) appearing at the Special Meeting and requesting a
return of the proxy. All shares represented by valid proxies will be exercised
in the manner specified thereon. If no specification is made, such shares will
be voted in favor of approval of the Merger Agreement and otherwise in the
discretion of the proxyholders named thereon in accordance with their best
judgment as to any other matters that may be voted on at the Special Meeting,
including among other things, a motion to adjourn or postpone the Special
Meeting to another time and/or place for the purpose of soliciting additional
proxies or otherwise; provided, however, that no proxy that is voted against the
proposal to adopt the Merger Agreement will be voted in favor of any adjournment
or postponement proposed for the purpose of soliciting additional votes in favor
of the Merger Agreement.

                                   THE MERGER
 
    THE FOLLOWING INFORMATION RELATING TO THE MERGER IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE MORE DETAILED INFORMATION CONTAINED ELSEWHERE IN
THIS PROSPECTUS/PROXY STATEMENT, INCLUDING THE ANNEXES HERETO, AND IN THE
DOCUMENTS INCORPORATED HEREIN BY REFERENCE. A COPY OF THE MERGER AGREEMENT IS
SET FORTH IN ANNEX A TO THIS PROSPECTUS/PROXY STATEMENT AND REFERENCE IS MADE
THERETO FOR A COMPLETE DESCRIPTION OF THE TERMS OF THE MERGER. SHAREHOLDERS OF
WTC ARE URGED TO READ THE MERGER AGREEMENT CAREFULLY.
 
GENERAL
 
   
    Subject to the terms and conditions of the Merger Agreement, WTC will merge
with SAS in a transaction in which WTC will be the surviving corporation and
will become a wholly-owned subsidiary of SNET. Upon consummation of the Merger,
at the Effective Time, each outstanding share of WTC Common Stock (other than
the Excluded Shares) will be converted into the right to receive that number of
shares of SNET Common Stock (including SNET Rights, as described below) equal to
the product of one share of SNET Common Stock times a fraction, the numerator of
which is $43.00 and the denominator of which is equal to the average of the
closing prices (the "Average Closing Price") of one share of SNET Common Stock
as reported on the NYSE for the ten trading days ending on the fifth business
day prior to the Effective Time (the "Merger Consideration"); provided, that in
the event the Average Closing Price is less than $30.00, then the Merger
Consideration shall be determined in accordance with the foregoing formula based
on a deemed Average Closing Price of $30.00 and WTC shall have the option to
consummate the Merger based on such deemed Average Closing Price and, if WTC
does not opt to do so, then SNET shall have the option to terminate the Merger
pursuant to the Merger Agreement; and in the event the Average Closing Price is
more than $49.00, then the Merger Consideration shall be determined in
accordance with the foregoing formula based upon a deemed Average Closing Price
of $49.00 and SNET shall have the option to consummate the Merger based on such
deemed Average Closing Price and, if SNET does not opt to do so, then WTC shall
have the option to terminate the Merger pursuant to the Merger Agreement.
    
 
    In the Merger, the SNET Shareholdings will be canceled and SNET will not be
entitled to receive the Merger Consideration therefor.
 
    No fractional shares of SNET Common Stock will be issued to WTC shareholders
in the Merger. Instead, SNET shall issue to each WTC shareholder otherwise
entitled to a fractional share a check for an amount of cash equal to the
fraction of a share of SNET Common Stock multiplied by $43.00.
 
EFFECTIVE TIME
 
    Subject to the conditions and obligations of the parties to the Merger
Agreement to effect the Merger, the effective time of the Merger (the "Effective
Time") will be at the time of the filing with the Secretary of State of
Connecticut of certificates of merger required under applicable law. Such filing
will be on the date of the closing of transactions under the Merger Agreement on
or such other date as the parties to the Merger Agreement shall agree. Such
closing of transactions is expected to occur on a date not later than ten days
following the receipt of all regulatory approvals for the Merger. (See "THE
MERGER -- Regulatory Approvals.") Subject to the foregoing, it is currently
anticipated that the Merger will be consummated in the second or third quarter
of 1997. The Board of Directors of WTC, SNET or SAS may terminate the Merger
under certain circumstances, including the failure of the DPUC to approve the
Merger by December 31, 1997. (See "THE MERGER--Conditions to Consummation;
Termination.")
 
DIVIDENDS ON WTC COMMON STOCK
 
    Until the Effective Time, shareholders of WTC remain entitled to receive
dividends on WTC Common Stock, if declared by the WTC Board. Under the Merger
Agreement, quarterly cash dividends of $.38 per share may be paid on WTC Common
Stock up to the Effective Time, if declared by the WTC
 
                                       14
<PAGE>
Board. On January 29, 1997, the WTC Board declared a regular quarterly cash
dividend of $.38 per share to shareholders of record as of February 14, 1997.
The dividend was paid February 28, 1997.
 
    After the Effective Time, WTC shareholders who receive shares of SNET Common
Stock in the Merger shall be entitled to receive dividends or other
distributions on SNET Common Stock issuable to them in the Merger, as set forth
below.
 
EXCHANGE OF WTC CERTIFICATES
 
    As promptly as practicable after the Effective Time, SNET will send or cause
to be sent to each holder of record of WTC Common Stock as of the Effective
Time, transmittal materials for use in exchanging all of such holder's
certificates representing WTC Common Stock for a certificate or certificates
representing the SNET Common Stock to which such holder is entitled, and a check
for such holder's fractional share interest and any dividends to which such
holder is entitled, as appropriate. The transmittal materials will contain
information and instructions with respect to the surrender and exchange of such
certificates.
 
    WTC SHAREHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE
THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS.
 
    Upon surrender of all of the certificates for WTC Common Stock registered in
the name of a holder of such certificates (or indemnity satisfactory to SNET and
the exchange agent selected by SNET if any of such certificates are lost, stolen
or destroyed), together with a properly completed letter of transmittal, such
exchange agent will mail to such holder a certificate or certificates
representing the number of shares of SNET Common Stock to which such holder is
entitled, all undelivered dividends or distributions in respect of such shares
and, where applicable, a check for any fractional share interest (in each case,
without interest).
 
    All shares of SNET Common Stock issued to the holders of WTC Common Stock
pursuant to the Merger will be deemed issued as of the Effective Time. SNET
dividends having a record date on or after the Effective Time will include
dividends on all SNET Common Stock issued in the Merger, but no dividend or
other distribution payable to the holder of record of SNET Common Stock at or as
of any time after the Effective Time will be distributed to the holder of any
WTC Common Stock certificates until such holder physically surrenders all such
certificates as described above. Promptly after such surrender, all undelivered
dividends and other distributions and, where applicable, a check for any
fractional share interest, will be delivered to such holder, in each case
without interest. SNET dividends having a record date before the Effective Time
(which record date may, in SNET's sole discretion, be the day immediately
preceding the Effective Time or any other day prior to the Effective Time) will
not include dividends on the SNET Common Stock issued in the Merger. After the
Effective Time, the stock transfer books of WTC will be closed, and there will
be no transfers on the transfer books of WTC of the shares of WTC Common Stock
that were outstanding immediately prior to the Effective Time.
 
    The Merger Agreement provides that as a condition to the obligation of SNET
to effect the Merger, WTC will deliver to SNET an agreement from each person who
may be deemed to be an "affiliate" (as defined in the Securities Act) relating
to the disposition of such affiliate's shares of SNET Common Stock. (See "RESALE
OF SNET COMMON STOCK.")
 
BACKGROUND AND REASONS
 
    WTC
 
    WTC is an independent local exchange carrier ("LEC") founded in 1899 and
provides telephone service to major portions of the Towns of Woodbury, Southbury
and Bethlehem, Connecticut. It also serves small portions of the Towns of Oxford
and Roxbury, Connecticut. WTC is one of approximately 1,300 independent LEC's in
the United States. As of December 31, 1996 WTC served 19,961 access lines.
 
                                       15
<PAGE>
    WTC provides telephone services in its service area to its customers through
central office switching equipment and cable, both underground and attached to
poles. WTC's lines and cables are interconnected with those of other telephone
companies in the United States and in other countries through the facilities of
SNET and other common carriers. WTC provides intrastate toll service under
terms, conditions and rates consistent with SNET tariffs, as approved by the
WTC's primary regulator, the DPUC. WTC also provides interstate access service
under terms, conditions and rates consistent with the National Exchange Carrier
Association ("NECA") access tariffs to other common carriers as approved by the
Federal Communications Commission.
 
    WTC is a public service company subject to regulation by the DPUC as to
intrastate rates and services, issuance of securities, reporting requirements
and other matters and has operated as a regulated monopoly in its telephone
franchise area. As such, it has largely been free from competition in offering
local and network access telephone service to its customers and is permitted by
the DPUC to earn a reasonable rate of return on its rate base.
 
   
    There is no market maker holding an inventory position in WTC Common Stock
and there is no active trading market for shares of WTC Common Stock. The prices
at which WTC Common Stock are traded are, however, presented through the NASDAQ
OTC Bulletin Board trading system under the symbol "WBTL". (See "THE
MERGER--Market Prices.")
    
 
    INDUSTRY OVERVIEW
 
    In recent years, the telecommunications industry has experienced fundamental
change in technology, demand for telecommunications services and competition. In
particular, digital technology has resulted in the convergence of voice, data
and video transmission. New services such as wireless, paging and the Internet
have developed. It became the consensus of legislators and regulators that
broader competition rather than broader regulation was the best way to bring the
benefits of technology and new telecommunications services to consumers.
 
    As a result, effective July 1, 1994, Connecticut enacted Public Act 94-83
(the "Connecticut Telecommunications Act"). This new law promoted competition,
required the unbundling of local exchange telephone network services, and
encouraged alternative forms of regulation to replace traditional rate-of-return
regulation. In conjunction with the DPUC's implementation of the Connecticut
Telecommunications Act, three dockets with respect to WTC were opened in
November 1994. No decisions have yet been rendered in connection with those
dockets.
 
   
    On February 8, 1996, the federal Telecommunications Act of 1996 (the
"Federal Telecommunications Act") was enacted. The intent of this law, which
substantially amended the Communications Act of 1934, is to promote competition
and reduce regulation in order to secure lower prices and higher quality
services for telecommunications consumers and encourage the rapid deployment of
new telecommunications technologies. Implementation is to occur primarily
through three major orders of the Federal Communications Commission ("FCC")
regarding interconnection, access charges and universal service.
    
 
    On August 8, 1996, the FCC issued its order and new regulations establishing
rules for interconnection between local exchange carriers and competitive
service providers. Portions of the order, particularly those relating to
pricing, have been challenged and are being reviewed by the U.S. Court of
Appeals. While small, rural telephone companies like WTC are initially exempt
from many of the requirements of the order, the long-term sustainability of such
an exemption for WTC is unlikely.
 
    While the legislative and regulatory changes described above may benefit new
market entrants, and may benefit large telephone companies such as the seven
Regional Bell Operating Companies, they may seriously threaten the viability of
small, rural telephone companies like WTC. Generally, these small companies lack
the economies of scale, financial resources, brand recognition and management
expertise to diversify into other lines of business and successfully compete
with large telecommunications providers.

    WTC'S STRATEGIC PLANNING
 
   
    WTC's management and the WTC Board responded to the opportunities and
challenges provided by the rapidly changing telecommunications industry by
engaging in a strategic planning process. At a meeting of the WTC Board on April
28, 1995, a presentation was made by Donald E. Porter, WTC's President. The
Board reviewed various strategic planning issues, including the possibility of
adopting a holding company structure to enable WTC to diversify into other
related businesses, as well as the impact of SNET's 36.5 percent equity
ownership in WTC. Commencing in the Spring of 1995, the Executive Committee of
the WTC Board began to deal specifically with strategic planning issues. The
Executive Committee is comprised of Messrs. J. Garry Mitchell, Walter F.
Torrance, Jr., Harmon L. Andrews, William C. Bassett and John A. Michaels. (In
the course of discussions regarding strategic planning and the Merger, including
voting on the Merger and related issues, the SNET designees on the WTC Board,
John Sadek and his successor, Michael Phelan, did not participate.)
    
 
    The result of the strategic planning process was a recognition by the WTC
Board and WTC's management of the following:
 
    - With the implementation of the Federal Telecommunications Act and the
      Connecticut Telecommunications Act, the traditional sources of revenue to
      WTC will in all likelihood erode over time as the full effects of
      deregulation and competition become evident.
 
    - WTC will be required to manage its business more aggressively and seek to
      exploit revenue opportunities in other than regulated areas.
 
    - WTC's management has limited experience outside of its traditional LEC
      operations.
 
    - To enter into any new businesses and services that will have the
      possibility of providing material increases in the revenues or profits of
      WTC would require the addition of new managers and/or training existing
      managers.
 
    - Any new businesses or services will result in a higher level of risk than
      has been experienced by WTC in its business operations in the past.
 
    The Executive Committee also considered whether a sale of WTC would enhance
shareholder value. The Executive Committee agreed that for the foregoing reasons
the price of WTC Common Stock, which traded in the $22.50 to $30.00 range during
1994 and the first half of 1995, would in all likelihood not increase
significantly, if at all, in the foreseeable future. Furthermore, the Executive
Committee realized that the future earnings of the WTC business would likely
erode over the foreseeable future for the reasons stated above and, therefore,
there was no assurance that the present level of dividends to WTC shareholders
could continue.
 
    In addition, the Executive Committee considered whether a sale would provide
a greater degree of liquidity to the shareholders who hold WTC Common Stock
which is not actively traded, and came to the conclusion that an exchange of WTC
Common Stock for an acquiror's stock which is broadly traded on a national
exchange or market, or cash, would provide WTC shareholders with increased
liquidity for their shares.
 
    The Executive Committee also assessed the risks of the uncertain
telecommunications environment and considered the effect of any weaknesses of
WTC in its ability to compete in the rapidly evolving telecommunications
industry.
 
    MERGER NEGOTIATIONS
 
    The Executive Committee and the WTC Board met during May and July 1995 to
discuss various strategic planning issues, including the possible sale of WTC.
On August 9, 1995, two members of the Executive Committee, J. Garry Mitchell and
Walter F. Torrance, Jr., met with John J. Miller, Vice
 
                                       17
<PAGE>
   
President and Treasurer of SNET, to discuss the strategic planning process and
to discuss, on a preliminary basis, whether SNET had an interest in selling the
SNET Shareholdings. Mr. Miller indicated that SNET was not interested in selling
its shares, but might be interested in discussing the acquisition of WTC shares
it did not own. On September 27, 1995, the Executive Committee met and agreed to
engage an outside professional to determine a possible range of values of WTC in
the event the WTC Board decided to seek to be acquired. In November 1995, SNET
and WTC entered into a nondisclosure agreement, and WTC provided SNET additional
information, which included annual and interim financial reports, a pertinent
data log, union agreements, NECA settlement excerpts, its 1995 Strategic Plan
and excerpts from DPUC filings.
    
 
    On November 20, 1995, Messrs. Mitchell and Porter and counsel to WTC met
with Gary Sugarman, the principal of Richfield Associates Inc. ("Richfield") to
discuss preparation of a valuation of WTC. Richfield is a Rochester, New York
based financial consulting firm with particular experience in the telephone
industry. On November 22, 1995, Richfield and WTC entered into a nondisclosure
agreement. Management of WTC provided Richfield with a variety of information
concerning its finances and business, including minutes of the WTC Board and
Executive Committee and WTC financial information.
 
   
    On January 22, 1996, Mr. Sugarman presented Richfield's assessment to the
Executive Committee. The conclusions reached by Richfield were presented to Mr.
Miller of SNET on March 25, 1996. Mr. Miller indicated SNET's lack of interest
in selling its shares of WTC but expressed an interest in exploring the
acquisition of the balance of the outstanding shares of WTC not owned by SNET.
Several weeks later, Mr. Miller suggested that SNET would consider offering SNET
Common Stock having a value of $37.00 per share in a tax-deferred transaction
for the WTC shares not owned by it. The offer would permit WTC shareholders to
defer taxes on the transaction.
    
 
    In order to assess SNET's indication of interest at the $37.00 level, the
WTC Board proposed in April 1996 that Richfield solicit indications of interest
from potential purchasers of WTC other than SNET. At the Executive Committee's
April 17, 1996 meeting and at the WTC Board meeting on April 24, 1996,
Richfield's plan to solicit indications of interest was discussed. The WTC Board
authorized Richfield to proceed, and summary information about WTC was prepared
and submitted to four potential purchasers identified by Richfield. During June
1996, Richfield presented preliminary indications of interest from two of the
potential purchasers.
 
    On July 5, 1996, Messrs. Mitchell, Porter and Torrance of WTC discussed with
Messrs. John Miller and Norman Steingard of SNET various options concerning a
sale or merger of WTC to or with a third party other than to or with SNET.
 
   
    During July and August 1996, Richfield sought clarification of the two
indications of interest. The first indication was a proposal to acquire all
shares of WTC Common Stock (including the SNET Shareholdings) for a price in the
$40.00 to $50.00 range. Based on the Executive Committee's understanding that
SNET was unwilling to sell its interest in WTC, this proposal was not pursued by
WTC. The Executive Committee requested additional information regarding the
second indication because, by its terms, such indication did not contain
sufficient information to fully analyze its viability.
    
 
    This indication of interest was from a privately held and recently organized
company seeking to acquire rural LEC's. The Executive Committee authorized
Richfield to further discuss this indication of interest in order to determine
on a preliminary basis as many of the terms and conditions as possible, as the
preliminary indication was in purchasing all of the outstanding shares of WTC
Common Stock, including the shares held by SNET, for $59.81 per share in a cash
transaction currently taxable to WTC shareholders or, alternatively, the same
cash price for the shares of WTC Common Stock owned by shareholders other than
SNET (also currently taxable to such WTC shareholders) but only if the party so
indicating an interest could reach appropriate agreements with SNET. The
Executive Committee, knowing that SNET was not interested in selling its shares
in WTC in that price range, sought to determine from the party the nature of the
agreements it would require from SNET and its other terms and conditions.
 
                                       18
<PAGE>
    In response to the inquiries of Richfield on behalf of the Executive
Committee, the party indicated the following:
 
    - In order to complete any acquisition of WTC, both debt and equity
      financing would have to be utilized. Accordingly, an appropriate structure
      or arrangement would need to be established in order to allow the acquiror
      to utilize the cash flow generated by WTC's business to provide interest
      and amortization payments for the acquisition debt. This would require a
      major recapitalization of WTC and/or a change in its existing capital
      structure.
 
    - The party desired to use WTC as a regional platform for further
      acquisitions of rural LEC's and for other acquisitions serving suburban
      markets in the northeast United States. Accordingly, it would require
      agreements with SNET to give the party the ability to substantially
      determine the management team responsible for operating WTC after the
      acquisition, the regulatory and market strategies to be employed by WTC,
      the budgeting and network plans to be implemented by WTC and other
      material events related to the overall performance of WTC after the
      acquisition.
 
    - Furthermore, the party suggested that, as one approach, it would form a
      holding company that would own all of the issued and outstanding shares of
      WTC. SNET would contribute its WTC shares and the party would contribute
      the cash necessary to acquire the shares of WTC Common Stock held by
      persons other than SNET. As a result, the party would own the majority of
      the stock of the holding company. The amount of cash contributed would
      provide the purchase price for the shares and would also partially
      capitalize the holding company in a sufficient amount to permit it to take
      advantage of additional growth opportunities.
 
   
    On August 9, 1996, the Executive Committee communicated to SNET the
foregoing proposed agreements and terms and conditions. On August 28, 1996, Mr.
Miller responded that SNET was not interested in pursuing the agreements, terms
and conditions. SNET believed such agreements were unnecessary because if the
party acquired the WTC Common Stock other than the SNET Shareholdings, it would
control the WTC Board and WTC's management and policies. To the extent that the
party wished SNET to enter into a voting agreement pursuant to which it would
not vote its shares in opposition to the stance of the party on any significant
matter requiring a shareholder vote, SNET believed that such an agreement was
not in its best interests as an investor. SNET further believed that a major
recapitalization of WTC and/or a change in WTC's existing capital structure, as
proposed by the party, was not in the best interests of SNET or its
shareholders, because WTC would become heavily burdened with debt, SNET would
have no input on the policies of the entity, and SNET believed that the DPUC
would not approve a highly leveraged acquisition of a public utility. Mr. Miller
expressed an interest on SNET's part of acquiring the WTC shares not owned by it
at a value in the range of $45.00 per share in a tax-deferred transaction,
provided that WTC's current financial position did not materially and adversely
change, and pending SNET's review of the impact on WTC of the regulations
implementing the Federal Telecommunications Act published earlier that month.
    
 
    During the early part of September 1996, WTC's counsel considered various
corporate and possible anti-competitive effects of any proposed transaction. The
Executive Committee recognized that WTC could not satisfy the conditions
indicated by the private party. Nevertheless, the Executive Committee believed
that because of changes in the telecommunications industry, WTC's position might
deteriorate if WTC deferred action on sale or merger options. Having sought
indications of interests from others, the Executive Committee determined that
SNET was, in effect, the only realistic buyer if a sale or merger were to occur
in the near future. Moreover, SNET's indicative value was significantly above
the historical high bid range for WTC Common Stock, and the transaction proposed
by SNET could be effected in a tax-deferred transaction, which would benefit WTC
shareholders. Based upon the foregoing, the Executive Committee determined that
it would not be in the best interest of WTC shareholders to pursue the
indication of interest from the private party described above.
 
                                       19
<PAGE>
    At a meeting on September 16, 1996, the Executive Committee, after reviewing
the alternatives available to WTC, recommended that the full WTC Board be asked
to authorize discussions with SNET regarding a possible merger. On September 18,
1996, the WTC Board authorized the Executive Committee to continue discussions
with SNET concerning a possible stock transaction valued in the range of $45.00
per share of WTC Common Stock.
 
   
    Representatives of SNET and its counsel met with Messrs. Mitchell, Porter
and Torrance of WTC and its counsel on September 25, 1996 to discuss SNET's
interest and the terms of a letter of intent. At this meeting, the parties
discussed WTC's financial position and SNET's ongoing review of the possible
impact of the Federal Telecommunications Act on the value of WTC. SNET indicated
that SNET's proposed value of $45.00 per share would be subject to adjustment.
On October 3, 1996 the WTC Board met and authorized the Executive Committee to
negotiate the terms of a letter of intent with SNET and to engage McDonald to
evaluate the fairness, from a financial point of view, to WTC shareholders of
any proposal that SNET might make. WTC then entered into an engagement letter
with McDonald. (See "THE MERGER--Opinion of Financial Advisor.")
    
 
    During early October 1996, negotiations continued between SNET, WTC and
their respective counsel regarding the terms (including the value to determine
the exchange ratio for shares of WTC Common Stock) of any possible transaction
and the terms of a letter of intent. During these negotiations, SNET proposed
that WTC shareholders would receive SNET Common Stock valued at $41.00 as the
price it was willing to pay for WTC shares due to the potentially adverse effect
of the Federal Telecommunications Act on WTC. Through negotiation, this value
was raised to $43.00 (in a tax-deferred exchange).
 
    On October 21, 1996, the WTC Board met to discuss the status of negotiations
with SNET and the terms of a proposed letter of intent between WTC and SNET,
copies of which were delivered to each member of the WTC Board. Representatives
from McDonald were also in attendance at the meeting, as were counsel to WTC.
The terms of the letter of intent were considered, including the proposed
consideration of $43.00 per share of WTC Common Stock in a tax-deferred
transaction. The representatives of McDonald present at the meeting made
presentations to the WTC Board and reviewed various aspects of the Merger as set
forth in the letter of intent, including the financial terms and conditions of
the Merger. The Board reviewed with counsel the terms of the letter of intent
and unanimously (with the exception of the director affiliated with SNET who did
not participate in such discussions) voted to accept SNET's offer and authorized
the Chairman of the Board to execute and deliver the letter of intent to SNET as
in the best interests of the WTC shareholders.
 
    WTC'S REASONS FOR THE MERGER
 
    The WTC Board (other than the director affiliated with SNET who has
abstained from this matter) believes that the Merger will benefit WTC, its
shareholders and its employees for the reasons discussed below. In the following
discussions, references to WTC's Board exclude the director affiliated with
SNET.
 
    Given the WTC Board's familiarity with WTC's business, financial condition,
earnings and prospects, as well as the current conditions in the
telecommunications industry, the WTC Board believes that the Merger offers the
WTC shareholders fair value for their shares of WTC Common Stock and liquidity
for their investment therein.
 
    In reaching its determinations and recommendations, the WTC Board considered
a number of factors, including, without limitation, the following factors which
the WTC Board considered material:
 
    - The WTC Board noted that the $43.00 per share sale price offered by SNET
      was a substantial premium over the $22.50 to $30.00 range at which the WTC
      shares had traded from 1994 to 1996. (See "THE MERGER--Market Prices.")
 
    - The WTC Board's view that it was unlikely that in the long term WTC could
      remain financially viable as an independent LEC, and that WTC would be at
      a competitive disadvantage as an LEC
 
                                       20
<PAGE>
      attempting to enter into new businesses to compete in a rapidly changing
      telecommunications industry.
 
    - As shareholders of SNET, the former WTC shareholders would hold stock in a
      company that was in the forefront of providing telephone, video and data
      services; and the Merger will give WTC access to increased financial,
      technological and managerial resources required to compete effectively in
      the rapidly changing regulatory, technological and competitive environment
      of the telecommunications industry.
 
    - WTC would face uncertainty in the event WTC were to remain independent and
      be sold at some point in the future. The impact of the rapidly changing
      telecommunication industry could result in a price per share below the
      $43.00 per share price offered by SNET.
 
   
    - SNET Common Stock is listed on the New York Stock Exchange and Pacific
      Stock Exchange, is actively traded and can be readily sold by WTC
      shareholders (other than affiliates of WTC) after the Merger.
    
 
    - The Merger will cause little, if any, dilution to SNET's reported earnings
      per share.
 
    - The opinion of McDonald that the consideration to be received by the
      shareholders of WTC in the Merger will be fair to such shareholders from a
      financial point of view.
 
    - SNET's position as a 36.5 percent owner of WTC Common Stock could enable
      it to prevent a merger or sale of assets to an unaffiliated acquiror
      (which would require the affirmative vote of two-thirds of the WTC Common
      Stock under Connecticut law), although it would not prevent a tender offer
      for WTC Common Stock.
 
    - The Merger is structured to qualify as a tax-deferred reorganization under
      the Internal Revenue Code, meaning that WTC shareholders generally would
      not be required to pay taxes in connection with the exchange of their
      shares of WTC Common Stock for SNET Common Stock until they sold their
      SNET Common Stock. (See "THE MERGER--Certain Federal Income Tax
      Consequences.")
 
    - The likelihood that WTC as a wholly-owned subsidiary of SNET would become
      a stronger competitor, which would likely enhance employment opportunities
      for WTC's current employees, all of whom will remain employed following
      the Merger.
 
    - The Merger in all likelihood would have a favorable effect on the
      community, suppliers and customers of WTC.
 
    WTC Board did not assign specific or relative weights to the factors noted
above and considered other factors as well.
 
    SNET'S REASONS FOR THE MERGER
 
    SNET believes that the Merger will provide the best opportunity for WTC and
SNET to solidify their business arrangements and position both companies to
compete in the future. In addition, as a current WTC shareholder, SNET believes
that the Merger will enhance WTC's ability to compete thereby preserving the
value of SNET's investment for the benefit of its shareholders.

OPINION OF FINANCIAL ADVISOR
 
    WTC retained McDonald as its financial advisor to render an opinion to the
WTC Board concerning the fairness, from a financial point of view, to WTC's
shareholders, of the Merger Consideration to be paid pursuant to the Merger
Agreement. McDonald was retained by WTC on the basis of, among other things, its
experience and expertise and familiarity with the telecommunications industry.
As part of its investment banking business, McDonald is customarily engaged in
the valuation of businesses and securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and estate planning purposes.
 
    Representatives of McDonald attended the October 21, 1996 meeting of the WTC
Board at which the directors considered the letter of intent submitted by SNET
with respect to the proposed Merger. At such meeting, representatives of
McDonald made presentations and reviewed various aspects of the Merger as set
forth in such letter, including the financial terms and conditions of the
Merger.
 
   
    Representatives of McDonald also attended the December 6, 1996 meeting of
the WTC Board at which the directors considered the Merger proposal. McDonald
advised the WTC Board that, at the request of the WTC Board, McDonald would be
in a position to render a written opinion as to the fairness to the WTC
shareholders, from a financial point of view, of the Merger Consideration to be
paid the holders of the issued and outstanding shares of WTC's Common Stock
pursuant to the Merger Agreement. On March 10, 1997, the WTC Board requested,
and McDonald delivered, such opinion, that the Merger Consideration to be paid
to WTC shareholders is fair from a financial point of view. The full text of
McDonald's opinion dated as of March 10, 1997 is attached as ANNEX B to this
Prospectus/Proxy Statement and is incorporated herein by reference. The
description of the opinion set forth herein is qualified in its entirety by
reference to ANNEX B. Holders of WTC Common Stock are urged to read the opinion
in its entirety for a description of the procedures followed, assumptions and
qualifications made, matters considered, and limitations undertaken by McDonald.
    
 
    MCDONALD'S OPINION IS DIRECTED TO THE BOARD OF DIRECTORS OF WTC AND
ADDRESSES ONLY THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, TO THE SHAREHOLDERS
OF WTC OF THE MERGER CONSIDERATION TO BE PAID TO THE SHAREHOLDERS OF WTC
PURSUANT TO THE MERGER AGREEMENT AS OF THE DATE OF THE OPINION. THE OPINION DOES
NOT CONSTITUTE A RECOMMENDATION TO ANY SHAREHOLDER AS TO HOW SUCH SHAREHOLDER
SHOULD VOTE AT THE WTC SPECIAL MEETING.
 
   
    In connection with rendering its opinion, McDonald reviewed and analyzed,
among other things: (i) the Merger Agreement, including the exhibits and
schedules thereto; (ii) certain correspondence between WTC and SNET and between
WTC and other prospective buyers; (iii) certain publicly available information
concerning WTC, including WTC's audited financial results for the three year
period ended December 31, 1996 as reported in the Annual Reports on Form 10-K of
WTC for each of the two years ended December 31, 1996 and unaudited interim
financial information set forth in WTC's Quarterly Reports on Form 10-Q for each
of the three quarters ended September 30, 1996; (iv) certain other internal
information, primarily financial in nature and including projections, concerning
the business and operations of WTC furnished to McDonald by WTC for purposes of
its analysis; (v) certain publicly available information concerning the trading
of, and the trading market for, WTC Common Stock and SNET Common Stock; (vi)
certain publicly available information concerning SNET, including reports
published by equity analysts with other investment banking firms containing
annual earnings estimates for SNET through 2000; (vii) certain publicly
available information with respect to certain other companies that McDonald
believed to be comparable to WTC or SNET and the trading markets for certain
such other companies' securities; and (viii) certain publicly available
information concerning the nature and terms of certain other transactions that
McDonald considered relevant to its inquiry. McDonald also had discussions with
certain officers and employees of WTC and SNET to discuss their respective
businesses and prospects, as well as other matters it believed to be relevant to
its inquiry.
    
 
                                       22
<PAGE>
    McDonald was not engaged to verify and relied, without independent
verification, upon the accuracy and completeness of all of the financial and
other information reviewed by it for purposes of its opinion. McDonald also
relied upon the management of WTC as to the reasonableness and achievability of
the financial and operating projections (and the assumptions and bases therefor)
provided to it, and assumed that such projections and forecasts reflect the best
currently available estimates and judgments of WTC's management and that such
projections and forecasts will be realized in the amounts and in the time
periods currently estimated by the management of WTC. With respect to SNET,
McDonald assumed that the assumptions underlying published third party earnings
estimates for SNET are reasonable and that such earnings will be realized in the
amounts and in the time periods contemplated thereby. McDonald was not engaged
to assess the achievability of such projections or the assumptions on which they
were based and expressed no view as to such projections or assumptions. McDonald
was not engaged to, and did not, make an independent evaluation or appraisal of
the assets and liabilities of WTC or SNET and was not furnished with any such
evaluation or appraisal. McDonald was informed by WTC and assumed for the
purposes of its opinion that the Merger will qualify as a reorganization under
applicable provisions of the Internal Revenue Code.
 
   
    McDonald was not engaged to solicit indications of interest from any
potential acquiror. Based upon discussions with WTC and its counsel, McDonald
assumed for purposes of its analysis that, under applicable provisions of
Connecticut law and WTC's charter documents, SNET's ownership of shares
representing more than one-third of the voting power of WTC provides it with the
ability to effectively block the sale of WTC to any other party in a merger or
sale of all or substantially all of WTC's assets. Because of uncertainties
concerning the legal effect of SNET's position on the comparative rights of SNET
and other shareholders of WTC, McDonald conducted the various analyses
summarized below with and without a discount for the potentially non-controlling
position of WTC's public shareholders.
    
 
   
    The following is a summary of analyses presented orally by McDonald to the
Board of Directors on March 10, 1997 (the "McDonald Report") in connection with
its opinion:
    
 
   
    COMPARABLE COMPANY ANALYSIS.  McDonald compared selected historical and
market value multiples of two groups of public companies that it deemed to be
comparable to WTC. For purposes of its analysis, McDonald identified five small,
independent local exchange carriers (collectively, the "LECs") that it believed
to be comparable to WTC. In McDonald's judgment, many of these LECs are involved
in telecommunications businesses with significantly more attractive business
prospects than those of WTC. McDonald also performed an identical analysis of
nine large telecommunication service providers with local exchange activities,
including Regional Bell Operating Companies and SNET (collectively, the
"RBOCs"). These RBOCs are significantly greater in size, possess securities that
trade more actively and are beginning to enter businesses with more attractive
business prospects than those of WTC, but in McDonald's judgment, share many
common characteristics with WTC in their main local exchange business
activities. The LECs used in McDonald's analysis were CFW Communications
Company, CT Communications, Hector Communications Corporation, Hickory Tech
Corporation and North Pittsburgh Systems, Inc. The RBOCs used in McDonald's
analysis were Ameritech, Bell Atlantic, Bell South Corporation, GTE Corporation,
NYNEX Corporation, Pacific Telesis Group, SBC Communications, SNET and US West
Communications Group. For each of these two groups of companies, McDonald
calculated a range of values based upon the market value multiples and applied
these multiples to the relevant historical results of WTC in order to determine
a range of implied values for WTC. No company used in McDonald's analysis was
identical to WTC. Accordingly, McDonald considered the market multiples for the
composite of comparable companies to be more relevant than the market multiples
of any single company.
    
 
   
    Using the closing prices of each of the companies within the two groups on
March 7, 1997, McDonald calculated multiples of revenue, earnings before
interest, taxes, depreciation and amortization ("EBITDA"), access lines and net
income for the comparable companies for the twelve months ended December 31,
1996 in order to develop a valuation range for WTC. McDonald calculated high,
median
    
 
                                       23
<PAGE>
   
and low multiples for the comparable company groups, and applied these multiples
to WTC's results for the same period. Based upon its analysis of the LECs,
McDonald applied multiples to WTC ranging from 2.07x to 7.10x revenues, 5.68x to
12.54x EBITDA, 2.90x to 8.34x access lines and 13.45x to 28.85x net income.
Based on its analysis of the RBOCs, McDonald applied multiples to WTC ranging
from 1.54x to 3.07x revenues, 4.08x to 7.50x EBITDA, 1.34x to 2.85x access lines
and 12.19x to 16.66x net income. These multiple ranges compare to historic
multiples for WTC for such period of 2.61x revenues, 4.98x EBITDA, 1.89x access
lines and 11.65x net income.
    
 
   
    Application of LECs' revenue multiples to WTC's revenues for the twelve
months ended December 31,1996 resulted in an indicated equity value range of
$22.8 million to $95.0 million, with a median value of $74.4 million.
Application of the LECs' EBITDA multiples resulted in an indicated equity value
range for WTC of $36.1 million to $88.0 million, with a median value of $83.1
million. Application of the LECs' access line multiples to WTC resulted in an
indicated equity value range for WTC of $50.7 million to $165.9 million, with a
median value of $60.7 million. Application of the LECs' net income multiples to
WTC resulted in an indicated equity value range for WTC of $35.5 million to
$76.2 million, with a median value of $64.5 million. Application of the RBOCs'
revenue multiples to WTC's revenues for the twelve months ended December 31,1996
resulted in an indicated equity value range of $15.2 million to $37.1 million,
with a median value of $33.1 million. Application of the RBOCs' EBITDA multiples
resulted in an indicated equity value range for WTC of between $23.8 million to
$49.8 million, with a median value of $40.7 million. Application of the RBOCs'
access line multiples to WTC resulted in an indicated equity value range for WTC
of $19.7 million to $49.8 million, with a median value of $29.0 million.
Application of the RBOCs' net income multiples to WTC resulted in an indicated
equity value range for WTC of $32.2 million to $44.0 million, with a median
value of $40.9 million.
    
 
   
    The indicated equity value ranges suggested by McDonald's analysis of the
LECs implied a value of between $29.69 and $206.73 for each WTC share, before
taking into account any discount for the potentially non-controlling status of
the WTC shares held by the public. With respect to the RBOCs, McDonald's
analysis implied a value of between $19.76 and $64.79 for each WTC share. After
applying a 20% lack of control discount, McDonald's analysis implied a value of
between $23.75 and $165.39 for each WTC share in the case of the comparable
LECs, and between $15.81 and $51.83 in the case of the RBOCs. These implied
values compare with the Merger Consideration of $43.00 per share specified in
the Merger Agreement. Before applying any discount, the Merger Consideration
contemplated by the Merger Agreement is at the low end of the range of fairness
based on McDonald's analysis of the LECs multiples, but approximates the median
of the various multiple analyses conducted with respect to the RBOCs.
    
 
   
    ANALYSIS OF SELECTED ACQUISITION TRANSACTIONS.  In order to assess market
pricing for recent acquisitions of small telecommunications services providers
offering local exchange services, long distance services, or both, McDonald
identified four transactions completed during 1995 and 1996. These transactions
included Telephone & Data Systems' acquisitions of Arvig Telephone, Deposit
Telephone Company and Camden Telephone, and Conestoga Enterprises' acquisition
of Buffalo Valley Telephone. McDonald analyzed the range of last twelve month
sales, EBITDA and net income multiples represented by the purchase price paid in
the transactions it reviewed. Sales multiples ranged from 1.6x to 5.1x, with a
median of 4.3x. EBITDA multiples ranged from 6.1x to 8.4x, with a median
multiple of 7.4x, and net income multiples ranged 12.5x to 25.6x with a median
of 23.1x. These valuation techniques resulted in an implied equity value for WTC
ranging from a low of $15.8 million to a high of $67.6 million, and suggested an
implied value of between $20.50 and $87.90 per WTC share, before applying any
discount for the potentially non-controlling status of the WTC shares held by
the public. The Merger Consideration of $43.00 is within this range.
    
 
    Because of the relatively small number of transactions for which financial
information was available, McDonald did not attach significant weight to the
acquisition transactions analysis described above in rendering its opinion.
 
                                       24
<PAGE>
    No company or transaction used in the comparable companies and comparable
transactions analyses for comparative purposes is identical to WTC, SNET or the
Merger. Accordingly, an analysis of the results of the foregoing necessarily
involves complex considerations and judgments concerning differences in
financial and operating characteristics of the companies and other factors.
Mathematical analysis (such as determining the average or median) is not, in
itself, a meaningful method of using comparable company or transaction data.
 
   
    DISCOUNTED CASH FLOW ANALYSIS.  McDonald estimated the theoretical present
value of cash flows generated by WTC's operations based on the sum of (i) the
discounted cash flows which WTC could generate over a five-year period and (ii)
a terminal value for WTC which assumes that a buyer will place a certain value
on the cash flow generated by WTC in accordance with the final projected year in
management's base case and steady state projections. Management's base case
projections were prepared taking into account the anticipated effects of changes
in the regulatory environment on WTC's financial performance during the period
under evaluation. Management's steady state projections assume that the effects
of regulatory reform that we know of today and increasing competition manifest
themselves more slowly than under the base case scenario.
    
 
   
    McDonald's calculation of the theoretical terminal value of WTC was based on
a multiple of EBITDA in the fifth year. This terminal value and the cash flows
generated by WTC were discounted using a weighted average cost of capital that
in McDonald's judgment reflects the risks associated with the cash flows to
derive the value of the enterprise and, after subtracting outstanding net debt,
the value of the equity. McDonald derived discount rates of 8.95% to 10.95% and
exit multiples of EBITDA of 7.00x to 9.00x. Applying these discount rates and
exit multiples, McDonald estimated that, based on a discounted cash flow
analysis of management's base case projections, the present value of the equity
of WTC ranged from $29.2 million to $38.2 million (without giving effect to any
lack of control discount). This range of values implied a value of between
$37.94 and $49.63 per WTC share, as compared to the Merger Consideration of
$43.00 per share. Applying these same discount rates and exit multiples of
EBITDA to management's steady state projections, McDonald estimated that the
present value of WTC's equity ranged from $41.5 million to $56.4 million
(without adjustment for any lack of control discount). This range of values
implied a value of between $54.00 and $73.36 per WTC share, as compared to the
Merger Consideration of $43.00 per WTC share.
    
 
   
    The results of McDonald's discounted cash flow analysis indicated that,
before applying any discount for the potentially non-controlling position of the
public shareholders, the Merger Consideration fell within the range of fairness
under management's base case projections, but outside the range of fairness
under management's steady state projections. After applying a 20% discount to
the WTC's equity value for the potential lack of control by the public
shareholders, the results of McDonald's discounted cash flow analysis suggested
a per share value for WTC, based on management's base case projections, of
between $30.35 to $39.70. Application of the same discount to management's
steady state projections suggested a per share value of between $43.19 and
$56.68. Therefore, after applying this discount, the Merger Consideration fell
within or exceeded the range of values suggested by McDonald's discounted cash
flow analysis.
    
 
    Inherent in any discounted cash flow valuation are the use of a number of
assumptions, including the accuracy of management's projections, and the
subjective determination of an appropriate terminal value and discount rate to
apply to the projected cash flows of the entity under examination. Variations in
any of these assumptions or judgments could materially alter the results of a
discounted cash flow analysis.
 
    RELATIVE CONTRIBUTION ANALYSIS.  McDonald analyzed WTC's and SNET's relative
contributions to the combined company with respect to various indicators of
value, including access lines, revenues, EBITDA, net income and dividends and
compared this with the relative ownership of WTC shareholders in the combined
company after the Merger. Such analysis was considered on a percentage
contribution basis and
 
                                       25
<PAGE>
   
was made for the twelve months ended December 31, 1996 based upon WTC's and
SNET's historical and pro forma financial results.
    
 
   
    In order to calculate an implied value for WTC using contribution analysis,
McDonald divided WTC's per share contribution to each indicator of value by
SNET's contribution per share. This analysis suggested an exchange ratio ranging
from $0.591 to $1.167, as compared with an exchange ratio of 1.199 implied by
the March 7, 1997 closing price of $35.875 for SNET Common Stock and the Merger
Consideration of $43.00 per share for WTC Common Stock. Thus, the results
indicated that the Merger Consideration was within the range of fairness. The
results of McDonald's contribution analysis do not necessarily indicate the
contributions that the respective businesses may actually make in the future.
    
 
   
    STOCK TRADING HISTORY AND OTHER CONTEXTUAL ANALYSES.  McDonald examined the
history of trading prices and their relative relationships for both WTC Common
Stock and SNET Common Stock and performed certain other financial analyses.
These analyses did not focus on the Merger Consideration to be paid in the
Merger, but were undertaken to provide contextual data and comparative market
data to assist in assessing the market's valuation of WTC and SNET. McDonald
reviewed the daily closing prices of WTC and SNET and compared those prices with
indices of selected publicly traded companies in order to assess the relative
stock price performance of WTC, SNET and such indices. In addition, in order to
further assess the market valuation of the SNET stock to be received by WTC
shareholders, McDonald performed a discounted cash flow analysis of SNET. As
with its analysis of WTC, McDonald estimated the theoretical present value of
cash flows that were assumed to be generated by SNET's operations based on the
sum of (i) the discounted cash flows which WTC could generate over a five-year
period and (ii) a terminal value for SNET which assumes that a buyer will place
a certain value on the cash flow generated by SNET in accordance with the final
projected year in analysts' earnings projections for SNET. With respect to WTC,
McDonald also performed a dividend discount analysis, which assesses value by
discounting a series of future dividend payments. McDonald conducted this
dividend discount analysis with respect to management's base case and steady
state projections, and the results of this analysis suggested that WTC's stock
was trading at a premium to the discounted value of future dividend payments
under both sets of projections.
    
 
    The summary of the McDonald Report set forth above does not purport to be a
complete description of the presentation by McDonald of the McDonald Report to
WTC's Board of Directors or of the analyses performed by McDonald. The
preparation of a fairness opinion is not necessarily susceptible to partial
analysis or summary description. McDonald believes that its analyses and the
summary set forth above must be considered as a whole and that selecting
portions of its analyses, without considering all analyses, or of the above
summary, without considering all factors and analyses, would create an
incomplete view of the process underlying the analyses set forth in the McDonald
Report and its opinion. In addition, McDonald may have deemed various
assumptions more or less probable than other assumptions, so that the ranges of
valuations resulting from any particular analysis described above should not be
taken to represent the actual value of WTC or the combined company.
 
    In performing its analyses, McDonald made numerous assumptions with respect
to industry performance, general business and economic conditions and other
matters, many of which are beyond the control of WTC or SNET. The analyses
performed by McDonald are not necessarily indicative of actual values or actual
future results, which may be significantly more or less favorable than suggested
by such analyses. Such analyses were prepared solely as part of McDonald's
analysis of the fairness, from a financial point of view, of the Merger
Consideration to be paid by WTC and were discussed with the WTC Board at its
October 1996 meeting. The analyses do not purport to be appraisals or to reflect
the prices at which a company might actually be sold or the prices at which any
securities may trade at the present time or at any time in the future. In
addition, as described above, McDonald's presentation to WTC's Board of
Directors and opinion was one of many factors taken into consideration by the
Board in making its determination to approve the Merger Agreement.
 
                                       26
<PAGE>
    In the ordinary course of its business, McDonald may trade securities of WTC
and SNET for its own account and for the account of its customers and may at any
time hold a short or long position in such securities. McDonald has expressed no
opinion as to the prices at which shares of SNET's Common Stock may trade
following completion of the Merger.
 
    WTC paid McDonald a fee of $200,000 for its services pursuant to the
Engagement Letter. No portion of McDonald's fee is contingent upon the closing
of the transaction. WTC also agreed to reimburse McDonald for its reasonable
out-of-pocket expenses and to indemnify McDonald against certain liabilities,
including liabilities under the federal securities laws.
 
INTERESTS OF CERTAIN PERSONS
 
    GENERAL
 
   
    Certain members of WTC's management and the WTC Board have interests in the
Merger that are in addition to any interests they have as shareholders of WTC
generally. These interests include, among others, provisions in the Merger
Agreement relating to the indemnification of WTC's directors and officers,
directors' and officers' liability insurance, and certain other benefits, as
described below.
    
 
    DEFERRED COMPENSATION AGREEMENT
 
    Pursuant to the Agreement dated May 31, 1991 between WTC and J. Garry
Mitchell, WTC agreed to pay certain deferred compensation to Mr. Mitchell. Until
his retirement on August 31, 1993, Mr. Mitchell served as President and an
employee of WTC and as a director of WTC. Mr. Mitchell currently serves as
Chairman of the Board and as a director of WTC.
 
    The Agreement provides, in relevant part, that from Mr. Mitchell's
retirement from full-time employment with WTC, WTC will pay him $13,500 per year
as deferred compensation during the remainder of his life and, in the event that
he should die before receiving a total of $100,000, then the unpaid balance of
the $100,000 will be paid to his beneficiary. The rights to deferred
compensation under the Agreement are not assignable by Mr. Mitchell or his
beneficiary.
 
    CHANGE-IN-CONTROL AGREEMENT
 
    Pursuant to the Change in Control Agreement dated June 24, 1996, between WTC
and Donald E. Porter, President and Chief Executive Officer of WTC (the "Change
in Control Agreement"), Mr. Porter is entitled to certain payments if a
"Fundamental Change" occurs in connection with a "Change in Control" (as such
terms are defined in the Change in Control Agreement).
 
    Under the Change in Control Agreement, a Fundamental Change occurs if there
is a change in Mr. Porter's status, title, position or responsibilities; a
reduction in his compensation; a relocation of his principal office; termination
of his employment other than for cause or as a result of his death, disability
or retirement. (Mr. Porter, however, may be terminated for cause, as defined in
the Change in Control Agreement, in which event he is not entitled to any
benefits thereunder.)
 
    Pursuant to the Change in Control Agreement, a Change in Control occurs when
a person obtains more than 10 percent of the voting power of WTC (or, in the
case of SNET, SNET acquires additional shares of WTC Common Stock); or WTC
shareholders approve a merger effecting material changes in the composition of
the WTC Board, a sale of substantially all of WTC's assets, or a plan of
liquidation of WTC; or there are certain material changes in the composition of
the WTC Board; or WTC files a plan to merge or engage in a similar transaction
with the DPUC.
 
   
    In order for Mr. Porter to receive benefits under the Change in Control
Agreement, a Fundamental Change must have occurred within six months prior to,
or 24 months after, a Change in Control. If a Fundamental Change occurs within
such a period, Mr. Porter may terminate his employment with WTC
    
 
                                       27
<PAGE>
within 12 months after the occurrence of the Fundamental Change, in which case
Mr. Porter has the right to be paid the lesser of 220 percent of his then
current annual compensation or 299 percent of the average of his annual
compensation for the preceding five years. Notwithstanding the foregoing, if the
Fundamental Change which occurs is WTC's termination of Mr. Porter's employment
other than for cause, Mr. Porter is entitled to the foregoing payment without
having to take any affirmative action. In either case, Mr. Porter may designate
payment in a lump sum or in equal monthly installments.
 
    WTC's obligations under the Change in Control Agreement terminate as of the
end of the month after Mr. Porter's death, disability or retirement following a
Change in Control.
 
    Under the Change in Control Agreement, Mr. Porter is entitled to the payment
described above if a Fundamental Change occurs within 24 months after each of
the filing by WTC and SNET with the DPUC seeking approval of the Merger, the
approval of the Merger by WTC shareholders, SNET's acquisition of the WTC Common
Stock in connection with the Merger, or the occurrence of any subsequent event
that constitutes a Change in Control.
 
    SEVERANCE PAY
 
    The Merger Agreement provides that each management employee of WTC who is
not employed by SNET as of the Effective Time shall receive severance pay of a
type generally available to SNET management employees with similar lengths of
service and job descriptions.
 
    INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE
 
    The Merger Agreement provides that for three years after the Effective Time,
WTC as the surviving corporation in the Merger will (and SNET, for as long as it
controls WTC during such period, will cause WTC to) indemnify and hold harmless
each current director of WTC in their capacities as directors or officers to the
full extent provided in WTC Articles and WTC Bylaws (except for violations of
federal securities laws) with respect to any matter existing or occurring prior
to the Effective Time. Furthermore, for a period of three years following the
Effective Time, SNET agrees not to amend the existing indemnification provisions
of the WTC Articles or WTC Bylaws in a manner adverse to WTC's current directors
and officers.
 
    Additionally, the Merger Agreement provides that WTC as the surviving
corporation will (and SNET, for as long as it controls WTC during such period,
will cause WTC to) for six years following the Effective Time maintain policies
of officers' and directors' liability insurance maintained by WTC as of the date
of the Merger Agreement, or substantially equivalent coverage, with respect to
acts or omissions occurring prior to the Effective Time.
 
    DESIGNEE OF SNET ON WTC BOARD
 
    SNET has a contractual right to be represented by one director on the WTC
Board. From April 1990 to November 1995, John A. Sadek acted in that capacity.
Commencing January 1996, Michael Phelan has represented SNET on the WTC Board.
Mr. Phelan is the Vice President, Network Sales and Marketing of SNET.
 
    Neither Mr. Sadek nor Mr. Phelan participated in any discussions of the WTC
Board in connection with its deliberations described in "THE MERGER--Background
and Reasons; WTC" herein or in any vote of the WTC Board authorizing any action
in connection therewith or with the Merger, the Merger Agreement or the Special
Meeting.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a discussion of certain federal income tax consequences of
the Merger. The discussion is included for general information purposes only and
may not apply to special situations, such as WTC shareholders, if any, who
received their WTC Common Stock upon the exercise of employee stock options or
otherwise as compensation, that hold their WTC Common Stock as part of a
"straddle" or "conversion transaction", or that are insurance companies,
securities dealers, financial institutions or foreign persons.
 
    Carmody & Torrance, counsel for WTC, has advised WTC that in its opinion:
 
        (i) No gain or loss will be recognized for federal income tax purposes
    by WTC shareholders upon the exchange in the Merger of shares of WTC Common
    Stock for SNET Common Stock (except with respect to cash received in lieu of
    a fractional share interest in SNET Common Stock).
 
        (ii) The basis for SNET Common Stock received in the Merger by WTC
    shareholders (including the basis of any fractional share interest in SNET
    Common Stock) will be the same as the basis of the shares of WTC Common
    Stock surrendered in exchange therefor.
 
       (iii) The holding period of the shares of SNET Common Stock received in
    the Merger by WTC shareholders (including the holding period of any
    fractional share interest in SNET Common Stock) will include the holding
    period during which the shares of WTC Common Stock surrendered in exchange
    therefor were held by the WTC shareholders provided such shares of WTC
    Common Stock were held as capital assets.
 
        (iv) Cash received by a holder of WTC Common Stock in lieu of a
    fractional share interest in SNET Common Stock will be treated as received
    for such fractional share interest and, provided the fractional share would
    have constituted a capital asset in the hands of such holder, the holder
    should in general recognize capital gain or loss in an amount equal to the
    difference between the amount of cash received and the portion of the
    adjusted tax basis in the WTC Common Stock allocable to the fractional share
    interest.
 
   
    In addition, consummation of the Merger is conditioned, among other things,
upon receipt by WTC of an opinion of Carmody & Torrance, dated as of the
Effective Time, to the effect that (i) the Merger constitutes a reorganization
under Section 368 of the Internal Revenue Code of 1986, as amended and (ii) no
gain or loss will be recognized by WTC shareholders who receive shares of SNET
Common Stock in exchange for their shares of WTC Common Stock, except that gain
or loss may be recognized as to cash received in lieu of fractional share
interests. WTC shareholders who object to the Merger and perfect their rights to
be paid the fair value of their shares of WTC Common Stock in cash will
recognize taxable gain or loss for federal income tax purposes upon receipt of
such cash. (See "THE MERGER--Dissenter's Rights.") The tax opinions of Carmody &
Torrance summarized above are or will be based, among other things, on
representations relating to certain facts and circumstances of, and the
intentions of the parties to, the Merger.
    
 
    BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON THE
PARTICULAR CIRCUMSTANCES OF EACH WTC SHAREHOLDER AND OTHER FACTORS, EACH WTC
SHAREHOLDER IS URGED TO CONSULT SUCH HOLDER'S OWN TAX ADVISOR TO DETERMINE THE
PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE MERGER (INCLUDING THE
APPLICATION AND EFFECT OF STATE AND LOCAL INCOME AND OTHER TAX LAWS).

CONDUCT OF WTC BUSINESS PENDING CONSUMMATION
 
    Pending the Effective Time, WTC agreed with SNET to conduct its business
only in the ordinary course consistent with past practice and to use its best
efforts to preserve intact its business organization and good will.
 
    The Merger Agreement provides that until the Effective Time WTC will not,
without SNET's consent, incur or agree to incur any material liability or
obligation outside the ordinary course of its business; or without SNET's
consent or as contemplated by the Merger Agreement engage in activities or
transactions or make capital expenditures outside its ordinary course of
business and which are not material, individually or in the aggregate, to WTC's
business or financial condition.
 
    Furthermore, as more particularly set forth in the Merger Agreement, until
the Effective Time and without SNET's consent, WTC agreed not to take certain
actions, including, without limitation, making changes in its authorized capital
stock; issuing any stock options, warrants or other rights or agreements calling
for the issue, transfer, sale or delivery of its capital or other securities;
declaring, paying or setting aside for payment any stock dividend or offering
any split, division or combination or making any reclassification in respect of
its outstanding shares of capital stock; issuing, selling or exchanging or
delivering any shares of its capital stock (or securities convertible into or
exchangeable with or without additional consideration for such capital stock),
or entering into any agreement to take any action to do so; purchasing or
otherwise acquiring any of its outstanding shares of its capital stock, or
entering into any agreement to take any action to do so; declaring, paying or
setting aside for payment any dividend or distribution (whether in cash or
property) with respect to its capital stock other than its regular quarterly
cash dividends of no more than $.38 per share; amending its certificate of
incorporation or bylaws; waiving, releasing, granting or transferring any rights
of material value or modifying or changing in any material respect any material
existing license, lease, contract, benefit plan or other documents; increasing
compensation payable or to become payable to any of its executive officers
except in the ordinary course of business consistent with past practice; making
any payment or provision with respect to any bonus, profit sharing, employee
stock ownership, pension, retirement, deferred compensation, employment or other
payment plan, agreement or arrangement for the benefit of WTC employees other
than in the ordinary course of business consistent with past practice; granting
any stock options or stock appreciation rights; entering into any employment
agreement or other contract or arrangement with any executive officer with
respect to the performance of personal services not terminable without liability
by it on thirty days notice or less; making any loan or advance to, or entering
into any written contract, lease or commitment with, any officer, director or
shareholder of WTC; permitting any of its current insurance policies to be
canceled or terminated or any of the coverage thereunder to lapse unless
replaced in a similar manner; assuming, guaranteeing, endorsing or otherwise
becoming responsible for the obligations of any other individual, firm or
corporation or make any loans or advances to any other individual, firm or
corporation, except in the ordinary course of business; acquiring assets,
property, capital stock or business of any other person or disposing of its
assets, properties, capital stock or business other than in the ordinary course
of business, or consolidating or merging with or into any other person; making
any capital investment either by purchase of stock or securities, contributions
to capital, property transfers or otherwise, or by the purchase or lease of any
property or assets of any other person; writing-off as uncollectible any notes
or accounts receivable or writing down the value of any inventory other than in
immaterial amounts or in the ordinary course of business consistent with past
practice; disposing or permitting to lapse any rights in any patent, trademark,
tradename or copyright, or disclosing to any person not an employee or otherwise
dispose of any trade secret, process or know-how not theretofore a matter of
public knowledge except in certain circumstances; making any change in any
method of accounting or keeping its books of account or accounting practices
other than as disclosed in public filings; and entering into any agreement to do
any of the foregoing. In addition, WTC agreed to conduct its business only in
the ordinary course and consistent with past practices, and consistent with good
business practices to take such action as may be necessary to preserve its
material properties and assets; and to use its best efforts to preserve intact
the business organization of
 
                                       30
<PAGE>
WTC, to keep available the services of its operating personnel and to preserve
the goodwill of those having business relationships with it.
 
REGULATORY APPROVALS
 
    DPUC
 
   
    The Merger requires the advance approval of the DPUC. WTC and SNET expect to
file a joint application with the DPUC on or after the date on which this
Prospectus/Proxy Statement is mailed to shareholders. An order of the DPUC is
expected within 120 days following the submission of the joint application. The
DPUC may, but is not required, to hold hearings on the application. It may
approve or disapprove the application with such terms and conditions as it deems
necessary or appropriate. Any DPUC order is subject to appeal to the Connecticut
Superior Court.
    
 
    HSR ACT
 
   
    On December 26, 1996, SNET filed with the United States Department of
Justice and the Federal Trade Commission a Notification and Report Form pursuant
to requirements under the HSR Act, in connection with the proposed acquisition
by SNET of 63.5% of the voting securities of WTC that SNET presently does not
own. On February 7, 1997, WTC filed a Notification and Report Form pursuant to
the requirements of the HSR Act. Among the conditions to the Merger Agreement is
that any waiting period applicable to the Merger under the HSR Act shall have
expired or been terminated. The waiting period applicable to the Merger began to
run on February 10, 1997. The Department of Justice has requested, on an
informal basis, that each of WTC and SNET provide certain additional information
to the Department on a voluntary basis. WTC and SNET are complying with this
request.
    
 
   
    The Merger will not proceed in the absence of the requisite regulatory
approvals. There can be no assurance that such regulatory approvals will be
obtained, and if the Merger is approved, there can be no assurance as to the
date of any such approval. There can also be no assurance that such approvals
will not contain a condition or requirement that causes such approvals to fail
to satisfy the conditions set forth in the Merger Agreement. (See "THE
MERGER--Conditions of Consummation; Termination.")
    
 
ACQUISITION PROPOSALS; CANCELLATION FEE
 
    Under the Merger Agreement, WTC may not directly or indirectly solicit,
initiate, encourage or accept inquiries or proposals or furnish information
relative to, or participate in negotiations or discussions concerning, the
acquisition by any party other than SNET of a substantial interest in WTC's
assets or stock. However, if the WTC Board receives a bona fide third-party
offer for more than the Merger Consideration and also receives the requisite
opinion of its counsel as to its fiduciary duties, then WTC may (after notice to
SNET) provide non-public information to and negotiate with such third party.
 
    If WTC enters into negotiations and does not consummate a transaction with
such third party, SNET may terminate the Merger Agreement and WTC would be
obligated to pay SNET a cancellation fee of $500,000 as liquidated damages. If,
however, WTC so enters into negotiations and consummates a transaction with a
third party, or if WTC enters into negotiations with a third party in violation
of the Merger Agreement, SNET may terminate the Merger Agreement and WTC would
be obligated to pay SNET a cancellation fee of $1,500,000 as liquidated damages.
 
CONDITIONS TO CONSUMMATION; TERMINATION
 
    Consummation of the Merger is subject, among other things, to: (i) approval
of the Merger Agreement by the requisite vote of the shareholders of WTC; (ii)
receipt of the regulatory approvals referred to above; (iii) that there not be
pending, threatened or in prospect any suit, action, proceeding, investigation
or inquiry involving SNET or WTC or their respective directors or officers or
WTC's
 
                                       31
<PAGE>
securities with respect to their business or the Merger Agreement or the Merger
before any court or governmental agency which would render completion of the
Merger inadvisable or impractical; (iv) receipt by WTC of the opinion of Carmody
& Torrance, dated as of the Effective Time, as to certain federal income tax
consequences of the Merger; and (v) the shares of SNET Common Stock having been
approved for listing on the NYSE, subject to official notice of issuance.
 
    Consummation of the Merger is also subject to the satisfaction or waiver of
various other conditions specified in the Merger Agreement, including, among
others: (i) the delivery by WTC and SNET, each to each other, of (a) opinions of
their respective counsel and (b) certificates executed by certain of their
respective executive officers as to compliance with the Merger Agreement; and
(ii) the receipt by SNET of an agreement from each "affiliate" of WTC
restricting the sale of SNET Common Stock received by such affiliate in the
Merger.
 
    The Merger Agreement provides that, whether before or after the Special
Meeting and notwithstanding the approval of the Merger Agreement by the
shareholders of WTC, the Merger Agreement may be terminated and the Merger
abandoned at any time prior to the Effective Time: (i) by mutual consent of
SNET, SAS and WTC; (ii) by SNET, SAS or WTC if any of the conditions to such
party's closing the transaction has not been met or becomes incapable of
fulfillment; (iii) by SNET if the Average Closing Price is below $30.00 and WTC
does not elect to consummate the Merger; (iv) by WTC if the Average Closing
Price is above $49.00 and SNET does not elect to consummate the Merger; (v) by
SNET or SAS if WTC negotiates with, delivers information to or consummates a
transaction with a third party pursuant to Section 6.4 of the Merger Agreement
(see "THE MERGER--Acquisition Proposals; Cancellation Fee"); or (vi) by SNET,
SAS or WTC if the DPUC has not approved the Merger or, if approved by the DPUC
by December 31, 1997, the appeal period for such approval has not expired or the
approval is being appealed, but in either such event the Merger Agreement may be
terminated by SNET, SAS or WTC on March 31, 1998 if the appeal has not been
finally and favorably determined.
 
WAIVER; AMENDMENT
 
    Prior to the Effective Time any provision of the Merger Agreement may be:
(i) waived by the party benefitted by the provision; or (ii) amended or modified
at any time (including the structure of the transaction) by an agreement in
writing among the parties thereto approved by their respective Board of
Directors and executed in the same manner as the Merger Agreement, provided that
after approval by the shareholders of WTC, no amendment may be adverse to WTC
shareholders (including any adverse change in the terms of the consideration to
be received by the shareholders of WTC).
 
ACCOUNTING TREATMENT
 
    It is expected that the purchase method of accounting will be used to
reflect the Merger upon consummation. As required by generally accepted
accounting principles, under purchase accounting the assets and liabilities of
WTC as of the Effective Time will be recorded at their respective fair values
and added to those of SNET. Consolidated financial statements of SNET issued
after consummation of the Merger would reflect such values. Consolidated
financial statements of SNET issued before consummation of the Merger would not
be restated to reflect the acquired company's historical financial position or
results of operations.
 
    The impact of WTC's historical financial condition and results of operations
is not material to SNET's historical consolidated financial statements.
Accordingly, (i) WTC's results of operations will be included in the
consolidated financial statements of SNET from the Effective Time and (ii) pro
forma financial statements are not included herein.
 
                                       32
<PAGE>
EXPENSES
 
    Each party will pay its own expenses in connection with the Merger Agreement
and the consummation of the Merger, whether or not consummated. However, SNET
and WTC will share printing costs.
 
    Notwithstanding the foregoing, the Merger Agreement provides that if the
Merger is not consummated either due to the failure of either party to obtain
necessary regulatory approvals despite their best efforts or due solely to
SNET's fault, then SNET will reimburse WTC for its expenses up to $125,000 (if
due to such failure to receive approvals) or $300,000 (if due solely to SNET's
fault).
 
DISSENTERS' RIGHTS
 
    Any WTC shareholder who objects to the Merger Agreement shall have the right
to be paid the fair value of all shares of WTC Common Stock owned by such
shareholder in accordance with the provisions of Sections 33-855 to 33-872 of
the CBCA, a copy of which is set forth in ANNEX C to this Prospectus/Proxy
Statement. The right to be paid the value of such shares shall be such
shareholder's exclusive remedy as holder of such shares with respect to the
Merger, whether or not such shareholder proceeds as provided in CBCA Sections
33-855 to 33-872.
 
    Any WTC shareholder may elect to exercise such right by giving written
notice to WTC of such shareholder's intent to demand payment for such
shareholder's shares as provided in CBCA Section 33-861(a) prior to the
shareholders' voting on the proposal to approve the Merger Agreement and must
not vote such shares in favor of the proposal.
 
    If the Merger Agreement is approved, any such shareholder so notifying WTC,
provided none of such shareholder's shares shall have been voted in favor
thereof, may require WTC to purchase such shareholder's shares at fair value. As
provided in CBCA Section 33-862, WTC shall send a dissenters' notice to
shareholders who have complied with CBCA Section 33-861 no later than ten days
after the consummation of the Merger. The dissenters' notice sent by WTC shall
state where the demand for payment must be sent and where and when certificates
for certificated shares must be deposited; inform holders of uncertificated
shares to what extent transfer of the shares will be restricted after the
payment demand is received; supply a form for demanding payment that includes
the date of the first announcement to news media or to shareholders of the terms
of the Merger Agreement; and require that each shareholder asserting dissenters'
rights certify whether or not such shareholder acquired beneficial ownership of
the shares before that date. Finally, WTC shall set a date by which WTC must
receive the payment demand, which date may not be fewer than 30 nor more than 60
days after the date that the written dissenters' notice is delivered by WTC, and
WTC shall ensure that each such dissenters' notice is accompanied by a copy of
CBCA Sections 33-855 to 33-872.
 
    After a WTC shareholder receives such written dissenters' notice by WTC,
such shareholder must demand payment for such shareholder's shares and certify
whether such shareholder acquired beneficial ownership of such shares prior to
the date of the first announcement to the news media or to shareholders of the
terms of the Merger Agreement in accordance with the terms of the dissenters'
notice, as provided in CBCA Section 33-863(a). Such shareholder who demands
payment shall also be required to submit the certificate or certificates
representing such shareholder's shares to WTC in accordance with the terms of
the dissenters' notice. Such shareholder's failure to demand payment or deposit
his share certificates shall terminate such shareholder's rights under CBCA
Sections 33-855 to 33-872.
 
    If a WTC shareholder makes such demand for payment and submits such share
certificates to WTC, such shareholder shall retain all other rights of a WTC
shareholder until these rights are canceled or modified by the consummation of
the Merger as provided in CBCA Section 33-863(b). Any shareholder failing to
make such demand as described above shall be bound by the terms of the Merger
Agreement if it is approved.
 
                                       33
<PAGE>
    Pursuant to CBCA Section 33-864, WTC is further entitled to restrict the
transfer of uncertificated shares from the date the demand for payment by such
shareholders is received until WTC either consummates the Merger or fails to do
so within 60 days after the date set for demanding payment and depositing share
certificates. A WTC shareholder who has asserted dissenters' rights as to
uncertified securities retains all rights (other than the foregoing potential
restriction on transfer) of a WTC shareholder until such rights are canceled or
modified by the consummation of the Merger.
 
   
    After WTC either receives such demand for payment by a WTC shareholder, or
upon consummation of the Merger, WTC shall pay each shareholder who makes a
proper demand for payment pursuant to CBCA Section 33-863 the amount WTC
estimates to be the fair value of such shareholder's shares, plus accrued
interest as provided in CBCA Section 33-865(a). The payment by WTC to such
shareholder shall be accompanied by: WTC's balance sheet as of the fiscal year
ending not more than 16 months before the date of payment; an income statement
for that year; a statement of changes in shareholders' equity for that year; and
the latest available interim financial statements, if any; a statement of WTC's
estimate of the fair value of the shares; an explanation of how the interest was
calculated; a statement of the dissenting shareholder's right to demand payment
under CBCA Section 33-860; and a copy of CBCA Sections 33-855 to 33-872.
    
 
    Pursuant to CBCA Section 33-866, if the Merger is not consummated within 60
days after the date set for such shareholders' demand for payment and deposit of
share certificates, WTC shall return the deposited certificates and release the
transfer restrictions imposed on uncertificated shares. If the Merger is
consummated after the deposited certificates have been returned and the transfer
restrictions have been released, WTC shall send a new dissenters' notice under
CBCA Section 33-862 and repeat the payment demand procedure.
 
   
    WTC may elect to withhold payment to a shareholder who makes a demand for
payment pursuant to CBCA Section 33-863 if such shareholder was not the
beneficial owner of such shares before the date set forth in the dissenters'
notice as the date of the first announcement to the news media or to
shareholders of the terms of the Merger Agreement. Pursuant to CBCA Section
33-867(b), if WTC elects to withhold payment to such shareholder and the Merger
is consummated, WTC shall estimate the fair value of such shareholder's, shares,
plus accrued interest, and shall pay this amount to such shareholder if such
shareholder agrees to accept such payment in full satisfaction of such
shareholder's demand. WTC's offer to such shareholder shall be accompanied by a
statement of WTC's estimate of the fair value of such shares, an explanation of
how the interest was calculated and a statement of such shareholder's right to
demand payment under CBCA Section 33-868.
    
 
    Pursuant to CBCA Section 33-868, a dissenting WTC shareholder may notify WTC
in writing of such shareholder's own estimate of the fair value of his shares
and the amount of interest due, and demand payment of his estimate, less any
payment by WTC under CBCA Section 33-865, or may reject WTC's offer to purchase
such shareholder's shares, and demand payment for the fair value of such
shareholder's shares and interest owing, if: such shareholder believes that the
amount paid under CBCA Section 33-865 or offered under CBCA Section 33-867 is
less than the fair value of such shareholder's shares or that the interest due
is incorrectly calculated; WTC fails to make payment under CBCA Section 33-865
within 60 days after the date set for such shareholder's demand for payment; or
if the Merger is not consummated, and WTC fails to return the deposited
certificates or release the transfer restrictions imposed on uncertificated
shares within 60 days after the date set for such shareholder's demand for
payment. Such dissenting WTC shareholder must make a demand for payment pursuant
to CBCA Section 33-868(a) within 30 days after WTC makes or offers payment for
such shareholder's shares.
 
    If a WTC's shareholder's demand for payment under CBCA Section 33-868
remains unsettled, WTC shall commence a proceeding within 60 days after receipt
of such shareholder's demand for payment and file a petition in the Waterbury,
Connecticut Superior Court or before any judge thereof, requesting that the fair
value of the shares of such shareholder and the accrued interest thereon be
found and determined
 
                                       34
<PAGE>
   
as provided in CBCA Section 33-871(a). If WTC fails to timely commence such
proceeding, WTC shall pay each dissenting shareholder whose demand remains
unsettled the amount demanded. All shareholders making such demand for payment
as described above, whose demands remain unsettled, wherever residing, shall be
made parties to the proceeding. A copy of the petition shall be served on each
such shareholder who is a resident of Connecticut. Non-resident dissenting
shareholders may be served by registered or certified mail or by publication as
provided by law. The jurisdiction of the court shall be exclusive. The court
may, if it so elects, appoint one or more persons as appraisers to receive
evidence and recommend a decision on the question of fair value. The appraisers
shall have such power and authority as shall be specified in the order of their
appointment or an amendment thereof. Each WTC shareholder made a party to the
proceeding is entitled to judgment for the amount, if any, by which the court
finds the fair value of such shareholders' shares, plus interest, exceeds the
amount paid by WTC, or for the fair value, plus accrued interest, of the
after-acquired shares of such shareholders for which WTC elected to withhold
payment under CBCA Section 33-867. The costs and expenses, including the
reasonable compensation and expenses of court-appointed appraisers, of any such
proceeding shall be determined by the court and shall be assessed against WTC,
but all or any part of such costs and expenses may be apportioned and assessed
as the court may deem equitable against any or all shareholders who are parties
to the proceeding to whom WTC has made an offer to pay for the shares if the
court finds that the action of such shareholders was arbitrary or vexatious or
not in good faith in demanding payment under CBCA Section 33-868. Such expenses
also may include the fees and expenses of counsel and experts employed by any
party, and be entered against (a) WTC in favor of any or all dissenting
shareholders who are parties to the proceeding if WTC failed to substantially
comply with the requirements of CBCA Sections 33-860 to 33-868, inclusive, or
(b) either WTC or a dissenter, in favor of any other party, if the party against
whom the fees and expenses are assessed acted arbitrarily, vexatiously or not in
good faith with respect to rights provided by CBCA Sections 33-855 to 33-872,
inclusive. If the court finds that the services of counsel for any shareholder
were of substantial benefit to other dissenting shareholders similarly situated,
and that such fees should not be assessed against WTC, the court may find that
such fees should be paid out of the amounts awarded to the dissenting
shareholders who were benefitted.
    
 
    The foregoing is only a summary of the rights of an objecting holder of WTC
Common Stock. Any holder of WTC Common Stock who intends to object to the Merger
Agreement should carefully review the text of the applicable provisions of the
CBCA set forth in ANNEX C to this Prospectus/Proxy Statement and should also
consult with such holder's attorney. The failure of a holder of WTC Common Stock
to follow precisely the procedures summarized above and set forth in ANNEX C may
result in loss of dissenters' rights. No further notice of the events giving
rise to dissenters' rights or any steps associated therewith will be furnished
to holders of WTC Common Stock, except as otherwise required by law.
 
    In general, any objecting shareholder who perfects such holder's right to be
paid the fair value of such holder's WTC Common Stock in cash will recognize
taxable gain or loss for federal income tax purposes upon receipt of such cash.

    HISTORY AND BUSINESS
 
    WTC is a Connecticut corporation that was organized in 1899. WTC is engaged
in the business of furnishing local exchange telephone services, intrastate toll
services, and access to long distance telephone services (both intrastate and
interstate). WTC also sells telephone equipment and is an Internet Services
Provider. WTC currently is the primary provider of local exchange service in the
major portions of the Towns of Woodbury, Southbury, and Bethlehem, Connecticut,
and provides local exchange service to small portions of the Towns of Oxford and
Roxbury, Connecticut. WTC's business and number of customers has grown with the
increase in the population of its service area and the introduction of new
telecommunications applications (e.g., facsimiles, computer-based
communications).
 
   
    The total number of exchange lines in service at the end of each of the last
five years was 16,640 for 1992, 17,240 for 1993, 17,977 for 1994, 18,710 for
1995 and 19,961 for 1996. Approximately 59% of the WTC exchange lines are
located in the Town of Southbury, approximately 29% in the Town of Woodbury,
approximately 10% in the Town of Bethlehem and approximately 2% in the Towns of
Oxford and Roxbury. WTC provides local exchange service in its service area to
its customers through central office switching equipment and cables (underground
and attached to poles). Customers have the option of purchasing or leasing their
telephone instrument and other termination equipment from WTC or other sources.
WTC's lines and cables are interconnected with those of other telephone
companies in the United States and many other countries through the facilities
of SNET and other carriers. WTC provides intrastate toll service through SNET
tariffs, as approved by the DPUC. WTC provides intrastate and interstate access
through National Exchange Carrier Association Tariff No. 5. WTC has upgraded its
switching system to provide for equal access to inter-exchange carriers (e.g.,
AT&T Corp. ("AT&T"), Sprint Corp., MCI Communications Corp. ("MCI")).
    
 
    WTC, SNET Springwich, Inc. and certain other carriers are parties to a
limited partnership agreement pursuant to which WTC holds a 1% investment
interest in Springwich Cellular Limited Partnership, a limited partnership that
provides cellular mobile telephone service. WTC's allocation of profits and
losses are determined in accordance with such agreement.
 
SNET
 
    GENERAL
 
    Financial and other information relating to SNET, including information
relating to SNET's directors and executive officers, is set forth in SNET's 1995
Annual Report on Form 10-K, 1996 First, Second and Third Quarter Reports on Form
10-Q, 1996 Annual Meeting Proxy Statement and 1996 and 1997 Current Reports on
Form 8-K, copies of which may be obtained from SNET as indicated under
"AVAILABLE INFORMATION".
 
    HISTORY AND BUSINESS
 
    SNET was incorporated in 1986 under the laws of the State of Connecticut and
has its principal executive offices at 227 Church Street, New Haven, Connecticut
06510 (telephone number (203)
 
                                       37
<PAGE>
771-5200). SNET is a holding company engaged through its subsidiaries in
operations principally in Connecticut which expanded cellular services in Rhode
Island and certain areas in Massachusetts. SNET has business units in the
following telecommunications product groups; wireline; wireless; and information
and entertainment. Wireline includes The Southern New England Telephone
Company's telecommunications services; SNET America, Inc. (providing national
and international long-distance services to Connecticut customers); and SNET
Diversified Group, Inc. (providing premium telecommunications services and the
selling and leasing of communications equipment to residential and business
customers). Wireless includes SNET Cellular, Inc. and SNET Mobility, Inc.
(providing cellular (wholesale and retail), personal communications and paging
resale services). Information and entertainment includes directory publishing,
advertising and multimedia services. Non-telecommunications services include
SNET Real Estate, Inc. (engaging in leasing commercial real estate) and the
holding company (engaging in financial and strategic planning).
 
CERTAIN REGULATORY CONSIDERATIONS
 
    GENERAL
 
    WTC currently is the primary provider of local exchange service in the major
portions of the Towns of Woodbury, Southbury, and Bethlehem, Connecticut, and
provides local exchange service to small portions of the Towns of Oxford and
Roxbury, Connecticut (the area to which WTC provides exchange service being
sometimes hereinafter referred to as its "Service Area"). The Service Area was
established by agreement with The Southern New England Telephone Company, a
wholly-owned subsidiary of SNET and Connecticut's largest incumbent local
exchange carrier ("SNETCo"). The Service Area has been accepted by the DPUC and
is incorporated in tariffs filed by WTC with the DPUC; however, as described in
below, it is likely that recent Connecticut and federal legislation and
regulations adopted in connection therewith will enable competitive providers to
offer local service in the Service Area. WTC has no geographic limitation on its
unregulated business.
 
   
    As a public service company, WTC is subject to regulation by the DPUC as to
intrastate rates and services, issuance of securities, reporting requirements,
and other matters. WTC is also subject to regulation by the FCC as to interstate
access charges, reporting requirements, use of a uniform system of accounting
established by the FCC for telephone companies, and other matters.
    
 
    WTC provides intrastate toll service under terms, conditions and rates
consistent with SNETCo tariffs, as approved by the DPUC. The DPUC has recently
granted an application by SNETCo to reclassify its intrastate toll service as
competitive (as opposed to its previous designation as noncompetitive), thereby
allowing SNETCo greater flexibility with respect to its intrastate toll service
tariff. Given the recent change in such classification, WTC cannot anticipate
the precedential effect, if any, of that change which to date has not had any
material impact on WTC's operations or rates for intrastate toll service.
 
    Effective December 1, 1996, WTC installed and implemented a system to
provide intrastate equal access and presubscription in accordance with a DPUC
order. If a customer selects an intrastate carrier other than WTC, WTC will be
compensated for its services in connection with intrastate toll calls based on
access charges. WTC provides intrastate access under terms, conditions and rates
consistent with NECA Tariff No. 5. Given its recent adoption of intrastate equal
access and presubscription, WTC cannot anticipate the effect thereof, though WTC
expects that it will experience a loss, either from reduced revenue or increased
cost (or a combination of both). The amount of such loss also may be influenced
by the billing and collection arrangement, if any, that WTC maintains from time
to time with each of the carriers selected by customers.
 
    The method for compensating WTC for its services in connection with
interstate toll calls is based on access charges. WTC provides interstate access
through NECA Tariff No. 5. These access charges are paid by the interstate toll
carriers and end users. Under this system, WTC's revenues from interstate toll
calling
 
                                       38
<PAGE>
are not affected by the caller's choice of carrier. In 1992, WTC upgraded its
switching system to provide for equal access to interstate carriers. While some
local exchange carriers or their affiliates have entered into the competitive
interstate toll market as a result of legislative and regulatory initiatives,
WTC currently is not affiliated with any interstate offering.
 
    Historically, WTC and other local exchange carriers generally have competed,
on an unregulated basis, in the areas of billing and collection of interstate
services, and customer premises equipment. WTC offers customer premises
equipment on an unregulated basis under an FCC approved plan. An increasing
number of customers are providing their own equipment and other facilities in
lieu of equipment and facilities leased by WTC. WTC has no geographical
limitation on its unregulated business. WTC presently does not derive a material
amount of its revenue from its unregulated business.
 
    FEDERAL TELECOMMUNICATIONS ACT
 
    Since AT&T was required to divest itself of the 22 Bell operating companies,
regulatory and judicial rulings have generally increased competition within the
telephone industry, and have deregulated the provision of new terminal equipment
and enhanced services. In February 1996, the Federal Telecommunications Act
became law. The Federal Telecommunications Act, among other things, removes all
barriers to competition in the provision of local telecommunications services
and imposes certain obligations on local exchange carriers, like WTC, to
facilitate the introduction of competition to the local markets. In August 1996,
the FCC issued rules for interconnection between incumbent local exchange
carriers and competitive service providers. These rules have been the subject of
certain appeals currently pending in federal court, and some rules have been
stayed pending judicial review.
 
    Generally, the Federal Telecommunications Act requires all
telecommunications carriers to interconnect with each other and not to install
equipment that would preclude interconnectivity. Each local exchange carrier has
the duty to not impose unreasonable or discriminatory conditions on the resale
of its telecommunications services; provide, to the extent technically feasible,
number portability; provide dialing parity and nondiscriminatory access to
telephone numbers, operator services, directory assistance and directory
listing; allow access to rights of way; and establish reciprocal compensation
for the transport and termination of telecommunications.
 
    The Federal Telecommunications Act also imposes additional obligations on
all incumbent local exchange carriers to negotiate in good faith; provide
interconnection with the facilities and equipment of any requesting carrier;
provide nondiscriminatory access to unbundled network elements; offer any
telecommunication service for resale at wholesale rates (based on retail rates
less avoided costs); provide public notice of changes that would affect
interoperability; and provide for physical collocation of another carrier's
equipment necessary for interconnection or access to unbundled network elements.
 
    As an incumbent local exchange carrier, WTC is not only subject to the
duties generally applicable to all local exchange carriers, but also, unless
exempt, the additional obligations imposed on incumbents. The Federal
Telecommunications Act exempts "rural telephone companies" from such additional
obligations. WTC qualifies as such a rural telephone company because it provides
telephone exchange services to fewer than 50,000 access lines. Accordingly, WTC
is exempt from such additional obligations until it has received a bona fide
request for interconnection, services, or network elements, and the DPUC
terminates WTC's exemption because the request is not unduly economically
burdensome, is technically feasible, and is consistent with universal service
principles being developed under the Federal Telecommunications Act.
 
    To date one competitive carrier, TCI Telephony Services of Connecticut, Inc.
("TCI"), has requested that WTC initiate negotiations concerning
interconnection, services and network elements under the Federal
Telecommunications Act. WTC has advised TCI of its exemption as a rural
telephone company. On November 5, 1996, on TCI's application, the DPUC opened
Docket No. 96-11-06 (the "TCI Docket") to conduct the inquiries necessary to
determine whether to terminate WTC's exemption. WTC recently reached an
agreement in principle with TCI pursuant to which, among other things, WTC would
offer for
 
                                       39
<PAGE>
resale by TCI its local, retail telecommunications services at a wholesale price
reflecting a discount to be established by the DPUC in a SNETCo docket. In
connection with that agreement in principle, TCI withdrew its request to inquire
into WTC's exemption, without prejudice if WTC and TCI fail to reach a
definitive agreement on resale. Accordingly, the DPUC has closed the TCI Docket.
WTC anticipates that other competitive carriers may seek to resell WTC's local,
retail telecommunications services in a manner similar to TCI.
 
    It is likely that irrespective of WTC's obligations under the Federal
Telecommunications Act, in 1997 the DPUC will process WTC's dockets opened under
the Connecticut Telecommunications Act described below, subject to the
regulatory treatment of the Merger by the DPUC. If the DPUC terminates WTC's
exemption under the Federal Telecommunications Act or takes other action having
a similar effect, WTC anticipates that increased competition in the Service Area
will result in market penetration by other carriers, a reduction in WTC's
traditional sources of revenues, and increased expenses being incurred by WTC to
satisfy its regulatory obligations. In the absence of regulatory relief, local
exchange competition and the additional obligations imposed on incumbent local
exchange carriers under the Federal Telecommunications Act could seriously
threaten the viability of WTC in the long term. In any event, WTC believes that
based on the DPUC's actions in implementing the Connecticut Telecommunications
Act described below and general industry trends, it is likely that WTC could
face local exchange competition and could be materially and adversely affected
thereby in the long term.
 
    CONNECTICUT TELECOMMUNICATIONS ACT
 
    Prior to the enactment of the Federal Telecommunications Act, Connecticut
has taken steps to increase competition in the provision of local exchange
telephone service. Effective July 1, 1994, the Connecticut Telecommunications
Act promotes broader competition in the Connecticut telecommunications market,
with the stated goal of assuring high quality customer and technical services.
The Connecticut Telecommunications Act opens Connecticut telecommunications
services, including local exchange service, to full competition, and encourages
the DPUC to adopt alternative forms of regulation for telephone companies, like
WTC. The Federal Telecommunications Act is largely consistent with the
Connecticut Telecommunications Act, though the federal pricing provisions could
require WTC to charge competitors for services below WTC's cost of providing
such services.
 
    The DPUC has been charged with implementing the Connecticut
Telecommunications Act. More than 100 organizations have been certified to
operate as telecommunications companies in Connecticut, and approximately 20
(including AT&T, MCI and TCI) have been certified by the DPUC to provide local
service. The DPUC has held numerous hearings on, and is nearing the completion
of, implementation proceedings for SNETCo and certain other matters having
general application to the Connecticut telecommunications market. As a result of
proceedings in its dockets, SNETCo has already or shortly will unbundle its
local network, resell its local exchange services, and interconnect with
competitive carriers. SNETCo also has been granted an alternative form of
regulation and reclassified some of its services as competitive (as opposed to
emerging competitive or noncompetitive) under the Connecticut Telecommunications
Act.
 
    WTC has been participating in the proceedings involving the implementation
of the Connecticut Telecommunications Act, and the DPUC has opened three dockets
to examine the cost of providing service, intrastate depreciation rates, and
unbundling the local telecommunications network, respectively, for WTC. While
WTC's dockets have not been significantly advanced, the DPUC has indicated that
the principles developed in the SNETCo dockets are likely to apply equally to
WTC. WTC has consistently maintained that such a uniform application may not be
appropriate given certain significant differences between SNETCo and WTC. For
example, WTC has a different rate and access charge structure, almost all of
WTC's telecommunications services are currently classified as noncompetitive,
and there is no alternative regulation plan for WTC pending before the DPUC.
Unlike the Federal Telecommunications
 
                                       40
<PAGE>
Act, the Connecticut Telecommunications Act does not provide for any exemption
for WTC as a rural or small telephone company.
 
    Like the potential adverse effect of the Federal Telecommunications Act, the
implementation of the Connecticut Telecommunications Act, including the
introduction of local exchange competition to the Service Area, could seriously
threaten the viability of WTC in the long term. WTC anticipates that the DPUC
will process WTC's dockets in 1997, subject to the regulatory treatment of the
Merger. Moreover, it is likely that in the near future the DPUC will implement
local exchange competition in the Service Area, and as a result of the agreement
in principle reached between WTC and TCI in the TCI Docket, WTC will be required
to offer its local, retail telecommunications services to competitive carriers
at a wholesale price reflecting a discount to be established in a SNETCo docket.
While WTC cannot reasonably predict the effect of such competition at this time,
absent favorable regulatory treatment, including modifying some of the
principles developed in the SNETCo dockets, it is likely that local exchange
competition could materially and adversely affect WTC in the long term.

                       DESCRIPTION OF SNET CAPITAL STOCK
 
    THE DESCRIPTIVE INFORMATION SUPPLIED HEREIN OUTLINES CERTAIN PROVISIONS OF
THE SNET ARTICLES, THE SNET BYLAWS, THE RIGHTS AGREEMENT AND THE CONNECTICUT
BUSINESS CORPORATION ACT. THE INFORMATION DOES NOT PURPORT TO BE COMPLETE AND IS
QUALIFIED IN ALL RESPECTS BY REFERENCE TO THE PROVISIONS OF THE SNET ARTICLES,
THE SNET BYLAWS, THE RIGHTS AGREEMENT, AND THE CONNECTICUT BUSINESS CORPORATION
ACT.
 
    The authorized capital stock of SNET consists of 300 million shares of SNET
Common Stock, two million shares of preferred stock, par value $50 per share
("Preferred Stock"), and 50 million shares of preference stock, par value $1.00
per share ("Preference Stock"). As of the date of this Prospectus/Proxy
Statement there are 65,122,647 shares of SNET Common Stock issued and
outstanding and 2,758,512 shares of SNET Common Stock issued and held by SNET as
treasury shares. No shares of SNET Preferred Stock or Preference Stock were
issued and outstanding.
 
SNET COMMON STOCK
 
    Each share of SNET Common Stock is entitled to one vote, which may be cast
either in person or by proxy. Holders of SNET Common Stock have no cumulative
voting rights with respect to the election of directors and have no preemptive
or other rights to purchase additional securities of SNET.
 
    Each share of SNET Common Stock will have an equal and ratable right to
receive dividends, when, as and if declared by the board out of assets legally
available therefore and subject to the prior dividend rights of the holders of
any Preferred Stock or Preference Stock then outstanding. In the event of a
liquidation, dissolution or winding up of SNET, the holders of SNET Common Stock
will be entitled to share equally and ratably in the assets available for
distribution after the payment of liabilities, subject to any prior rights of
holders of any Preferred Stock or Preference Stock then outstanding.
 
PREFERRED STOCK
 
    The SNET Board of Directors ("SNET Board") has the authority to issue up to
two million shares of Preferred Stock in one or more series, to fix the terms,
limitations and relative rights and preferences of any unissued shares of
Preferred Stock and to fix the number of shares constituting any series and the
designations of such series, without any further vote or action by the
shareholders. Dividends on Preferred Stock of each series are cumulative from
the date or dates fixed with respect to such series and are paid or declared or
set apart for payment for all past dividend periods and for the current dividend
period before any dividends (except dividends payable in Preference or SNET
Common Stock) shall be declared or paid or set apart for payment on Preference
or Common Stock. The SNET Board, without shareholder approval, will be able to
issue Preferred Stock with voting and conversion rights which could adversely
effect the voting power of the holders of SNET Common Stock.
 
    Generally, holders of Preferred Stock have no right or power to vote on any
question or in any proceeding or to be represented at or to receive notice of
any meetings of shareholders. However, whenever dividends payable on Preferred
Stock at the time outstanding, the outstanding shares of Preferred Stock shall,
in addition to any other voting rights, have the exclusive right, voting
separately as a class and without regard to series, to elect, at the next
regular annual meeting of SNET, two directors of SNET and such right continues
until such time as all dividends on Preferred Stock to the latest dividend
payment date shall have been paid or declared or set apart for payment.
 
PREFERENCE STOCK
 
    The SNET Board has the authority to issue up to 50 million shares of
Preference Stock. The Preference Stock ranks after and is junior to the
Preferred Stock with respect to payment of dividends, the amount payable upon
shares in the event of involuntary liquidation and the amount payable upon
shares in the event of voluntary liquidation. The SNET Board has the authority
to fix and determine the terms,
 
                                       42
<PAGE>
limitations and relative rights and preferences of the Preference Stock and to
establish series and fix and determine the variation as among series.
 
RIGHTS PLAN
 
   
    Under a 1996 shareholders' rights plan ("Rights Plan"), effective February
11, 1997, each share of SNET Common Stock has a purchase right that entitles the
holder to purchase one hundredth of a share of Preference Stock at an exercise
price of $180.00 (collectively, the "SNET Rights"). The SNET Rights are not
exercisable or transferable apart from the SNET Common Stock until a person or
group has acquired, or has made an offer for, 20 percent or more of the
outstanding SNET Common Stock. In the event that a person or group acquires 20
percent or more of the outstanding SNET Common Stock, each outstanding SNET
Right, other than those held by the 20 percent acquiror, is entitled to
purchase, at the exercise price of the SNET Rights, a number of shares of SNET
Common Stock having a market value of two times the exercise price of the SNET
Right. At any time after any person or group acquires, or has made an offer for,
20 percent or more of the outstanding SNET Common Stock, and prior to the
acquisition by such person or group of 50 percent or more of the SNET Common
Stock, the Board may exchange the SNET Rights (other than the SNET Rights held
by such person or group), in whole or in part, at an exchange ratio of one share
of SNET Common Stock or one-one hundredth of a share of Preference Stock per
SNET Right. The SNET Rights are redeemable at one cent each prior to public
announcement that a person or group has acquired beneficial ownership of 20
percent or more of the outstanding SNET Common Stock. The SNET Rights expire on
February 11, 2007.
    
 
                    MATERIAL DIFFERENCES BETWEEN THE RIGHTS
                        OF HOLDERS OF SNET COMMON STOCK
                              AND WTC COMMON STOCK
 
    The following is a summary of material differences between the rights of
holders of SNET Common Stock and the rights of holders of WTC Common Stock. The
rights of the shareholders of SNET and WTC are currently governed primarily by
the CBCA and the respective articles of incorporation and bylaws of SNET and
WTC. The summary sets forth a list of the material differences and shareholders'
rights under the SNET Certificate and the SNET Bylaws and the WTC Certificate
and the WTC Bylaws. This discussion, however, is not and does not purport to be
an exhaustive list or to identify all differences that may, under any given fact
situation, be material to WTC shareholders. Moreover, this discussion is
qualified in its entirety by reference to the SNET Certificate, the SNET Bylaws,
the WTC Certificate, the WTC Bylaws and the CBCA.
 
ARTICLES OF INCORPORATION AMENDMENTS
 
   
    Under the CBCA, a corporation may amend its articles of incorporation by
vote of the board of directors and by the shareholders if the votes cast
favoring the action exceed the votes cast opposing the action, unless the
articles of incorporation requires a greater number of affirmative votes. The
SNET Certificate provides that the affirmative vote of at least 80 percent of
the voting power of all of the shares of SNET then entitled to vote generally in
the election of directors shall be required to amend or repeal or adopt any
provision inconsistent with provisions in the SNET Certificate relating to
classification of the SNET Board, the calling of special meetings, unanimous
voting for actions by consent and the amendment of the SNET Certificate and the
SNET Bylaws, unless such amendment, repeal or adoption has been recommended to
the shareholders by a vote of at least two-thirds of the SNET Board.
    
 
    The rights of the shareholders of WTC are also governed by the CBCA in
addition to the WTC Bylaws and the WTC Certificate. Those provisions of the CBCA
pertaining to an amendment of a corporation's articles of incorporation apply to
WTC in the same manner as outlined above. The WTC Certificate provides that the
affirmative vote of at least 80 percent of the voting power of all of the shares
 
                                       43
<PAGE>
of WTC then entitled to vote generally in the election of directors shall be
required to amend or repeal or adopt any provision inconsistent with the
provisions in the WTC Certificate denying preemptive rights (i.e., the right of
a shareholder to maintain its proportionate share of ownership by purchasing a
proportionate share of any new stock issues) to WTC shareholders; and
establishing qualifications for, and the minimum and maximum number of, WTC
directors and the classification of the WTC Board.
 
BYLAWS AMENDMENTS
 
   
    Under the CBCA, a corporation's board of directors may amend or repeal the
corporation's bylaws unless (i) the articles of incorporation or the CBCA
reserve this power exclusively to the shareholders in whole or in part or (ii)
the shareholders in amending or repealing a particular bylaw expressly provide
that the board of directors may not amend or repeal that bylaw. In addition, a
corporation's shareholders may amend or repeal the corporation's bylaws even
though the bylaws may also be amended or repealed by its board of directors. The
SNET Bylaws provide that the SNET Bylaws may be amended by the SNET Board or the
SNET shareholders provided that the amendment or repeal of provisions in the
SNET Bylaws relating to annual and special meetings of the SNET Board and
provisions relating to amending the SNET Bylaws require the affirmative vote of
the holders of at least 80 percent of the voting power of all of the shares of
SNET then entitled to vote generally in the election of directors.
    
 
    The rights of the shareholders of WTC are also governed by the CBCA in
addition to the WTC Bylaws and the WTC Certificate. Those provisions of the CBCA
pertaining to amendment or repeal of a corporation's bylaws apply to WTC in the
same manner as outlined above. The WTC Bylaws may be amended by the WTC Board or
the WTC shareholders provided that the amendment or repeal of provisions of the
WTC Bylaws relating to the removal of a director or the factors (e.g., WTC
ratepayers, WTC employees, the community and WTC's duties as a public service
company) that the Board may consider in the exercise of its judgment requires
the affirmative vote of the holders of at least 80 percent of the voting power
of all of the shares of WTC then entitled to vote generally in the election of
directors.
 
DISTRIBUTIONS TO SHAREHOLDERS
 
    Under the CBCA, a corporation has the power, subject to restrictions in its
articles of incorporation, to make distributions to its shareholders unless
after giving effect thereto the corporation would not be able to pay its debts
as they become due in the usual course of business or the corporation's total
assets would be less than the sum of its total liabilities plus, unless the
articles of incorporation permit otherwise, the amount that would be needed if
the corporation where to be dissolved at the time of the distribution to satisfy
the preferential rights upon dissolution of shareholders whose preferential
rights are superior to those receiving the distribution. The SNET Certificate
does not contain any limitations on such powers.
 
    The rights of the shareholders of WTC to receive distributions are also
governed by the CBCA in addition to the WTC Certificate. Those provisions of the
CBCA pertaining to distributions to shareholders apply to WTC shareholders in
the same manner as outlined above. The WTC Certificate does not contain any
limitation on such powers.
 
CLASSES OF DIRECTORS
 
   
    Under the CBCA, the articles of incorporation may provide for staggering the
terms of directors by dividing the total number of directors up to five groups,
with each group containing approximately the same percentage of the total, as
near may be. The SNET Certificate provides that the directors of SNET, other
than those who may be elected by the holders of any class of Preferred or
Preference Stock or any series thereof, shall be divided into three classes with
each class serving for staggered three year terms. The SNET Bylaws provide that
the SNET Board shall consist of not less than three nor more than 17 directors.
    
 
    The number and classes of WTC directors are also subject to the provisions
of the CBCA in addition to WTC Bylaws and the WTC Certificate. Those provisions
of the CBCA pertaining to the total number
 
                                       44
<PAGE>
   
and classes of permitted directors apply to WTC in the same manner as outlined
above. WTC is also governed by the WTC Certificate which provides that WTC shall
be managed by a Board of not less than five nor more than nine directors, all of
whom shall be shareholders of WTC. The WTC Certificate also provides that the
Board shall be divided into three classes of directors, specified as Classes I,
II, and III, as nearly equal in number as possible. The WTC Board fixes the
number of directors and each class thereof, and the classification of WTC
directors was effected at the 1989 annual meeting of WTC shareholders, during
which three Class I directors were elected for a one-year term, three Class II
directors were elected for a two-year term, and three Class III directors were
elected for a three-year term. After such initial classification, the WTC
Certificate further provides that successors to the class of directors whose
terms expire at the succeeding annual meetings of WTC shareholders shall be
elected for three-year terms. Directors are required to hold office until their
terms expire and until a successor is elected, except that if any director
attains the age of 70 during his term, such term shall end on the date of the
next annual meeting of the WTC shareholders and a replacement director shall be
elected to fill the unexpired term. The WTC Bylaws reference the WTC Certificate
for determining the qualifications, number and classes of directors.
    
 
REMOVAL OF DIRECTORS
 
    Under the CBCA, the shareholders may remove one or more directors with or
without cause unless the articles of incorporation provide that directors may be
removed only for cause. The SNET Bylaws provide that any director may be removed
from office at any time but only either by the affirmative vote of the holders
of at least 80 percent of the voting power of the shares of the corporation then
entitled to vote generally in the election of directors or by the SNET Board for
cause pursuant to a resolution approved by a majority of the entire SNET Board
upon not less than 10 nor more than 60 days written notice of the meeting at
which said resolution is to be presented.
 
    The removal of WTC directors is also governed by the CBCA in addition to the
WTC Bylaws and the WTC Certificate. Those provisions of the CBCA pertaining to
the removal of directors apply to WTC in the same manner as outlined above. The
WTC Bylaws provide that any director may be removed from office only for cause
by the affirmative vote of the holders of at least 80 percent of the voting
power of the shares of WTC then entitled to vote generally in the election of
directors, at a meeting the notice of which shall include a notice of such
proposed action. The WTC Bylaws further provide that cause for removal shall
only exist if a director has been convicted of a felony in a final adjudication
by a court of competent jurisdiction, or if a director has willfully engaged in
gross misconduct which is materially and demonstrably injurious to WTC. The WTC
Certificate does not contain any limitations on removal of directors.
 
MEETINGS OF SHAREHOLDERS
 
    Under the CBCA, special meetings of shareholders may be called by the board
of directors or the person or persons authorized to do so by the articles of
incorporation or bylaws or the holders of 35 percent, in the case of a public
company such as SNET, of all of the votes entitled to be cast on any issue
proposed to be considered at the proposed special meeting if such holders sign,
date and deliver to the corporation's secretary one or more written demands for
the meeting describing the purpose or purposes for which it is to be held. The
SNET Bylaws and the SNET Certificate provide that special meetings of
shareholders of SNET may be called only by the SNET Board pursuant to a
resolution approved by a majority of the entire SNET Board.
 
    Special meetings of WTC shareholders are also governed by the CBCA in
addition to the WTC Bylaws and the WTC Certificate. Those provisions of the CBCA
pertaining to special meetings of shareholders apply to WTC in the same manner
as outlined above, except that the holders of 10 percent of WTC Common Stock (as
opposed to 35 percent in the case of other public companies such as SNET) may so
request a special meeting. Such difference exists because SNET owned more than
10 percent of WTC
 
                                       45
<PAGE>
Common Stock as of February 1, 1988. The WTC Bylaws also provide that special
meetings of shareholders of WTC may be called at any time by WTC's President or
the WTC Board and that the President shall call a special meeting upon receipt
of a written request to do so by WTC shareholders representing at least 10
percent of the outstanding voting power. The WTC Certificate does not address
special meetings of shareholders.
 
ACTION BY SHAREHOLDERS WITHOUT MEETING
 
    Under the CBCA, any action which may be taken at a meeting of shareholders
may be taken without a meeting by consent in writing setting forth the action
taken or to be taken signed by all of the persons who would be entitled to vote
upon such action at a meeting or by their duly authorized attorneys. However, if
the articles of incorporation so provide, shareholder action may be taken by
written consent setting forth the action to be taken signed by all of the
persons holding such designated proportion, not less than a majority, of the
voting power of shares entitled to vote thereon or to take such action, as may
be provided in the articles of incorporation, or by their duly authorized
attorneys. The SNET Certificate provides that whenever shareholders are required
or permitted to take any action by vote, such action may be taken without a
meeting by written consent setting forth the actions so taken but only if such
written consent is signed by all of the persons who would be entitled to vote
upon such action at a meeting.
 
    Any action taken by WTC shareholders without a meeting is governed by the
CBCA in addition to the WTC Bylaws and the WTC Certificate. Those provisions of
the CBCA pertaining to action taken by shareholders without holding a meeting
apply to WTC shareholders in the same manner as outlined above. Neither the WTC
Bylaws nor the WTC Certificate contains any provisions specifically addressing
actions by shareholders without a meeting.
 
MERGERS AND ACQUISITIONS
 
    Under the CBCA, as a general matter, a corporation may merge with another
corporation or acquire all of the outstanding shares of another corporation if
the boards of directors and a majority of the votes entitled to be voted on the
merger or exchange by the shareholders of each corporation approve such merger
or exchange. Under prior law, which applies to corporations incorporated before
January 1, 1996, such as SNET and WTC, the affirmative vote of two-thirds of the
voting power of the holders of the outstanding shares entitled to vote thereon
is required, unless the corporation's articles of incorporation provide
otherwise. The SNET Certificate and the WTC Certificate, respectively, do not
provide for a majority vote of shareholders in connection with the approval of a
merger or share exchange, and therefore, the two-thirds voting requirement would
normally apply. The Merger, however, requires the affirmative vote of the
holders of 80 percent of the voting power of all of the outstanding shares of
WTC Common Stock and the holders of two-thirds of the outstanding shares of WTC
Common Stock other than WTC Common Stock held by SNET or any affiliate or
associate of SNET, as described under interested shareholder transactions below.
 
INTERESTED SHAREHOLDER TRANSACTIONS
 
   
    Under Connecticut law, certain transactions between a Connecticut
corporation and an interested shareholder (which is defined as a beneficial
owner of 10 percent or more of the voting power of the then outstanding shares
of voting stock of the corporation, or an affiliate of the corporation which at
any time during the two year period prior to the transaction was the beneficial
owner of 10 percent or more of the voting power of the then outstanding shares
of voting stock of the corporation), are prohibited absent compliance with
specific authorization requirements. CBCA Section 33-841 prohibits business
combinations (which include, without limitation, mergers, consolidations, sales
of assets having an aggregate book value of 10 percent or more of the total
market value of the outstanding shares of the corporation or its net worth, the
issuance or transfer of equity securities having an aggregate market value of
five percent or more of the total market value of the outstanding shares of the
corporation, the adoption of a resolution
    
 
                                       46
<PAGE>
   
calling for the liquidation or dissolution of the corporation proposed by or on
behalf of the interested shareholder, or reclassification of securities or
merger having the effect of increasing by five percent or more of the
proportionate amount of securities owned by an interested shareholder) with or
for the benefit of an interested shareholder or its affiliates or associates
unless such business combination is approved by the board of directors and
receives the affirmative vote of 80 percent of the voting power of all of the
outstanding shares of voting stock and two-thirds of the voting power of the
outstanding shares of the voting stock exclusive of the stock held by the
interested shareholder and its affiliates and its associates. The provision is
inapplicable where, among other things, the consideration to be received by
shareholders for their shares in the business combination meet certain pricing
and form criteria. Connecticut corporations are permitted to exclude certain
business combinations in certain instances from the voting requirements of this
provision by board resolution. The WTC Board has not adopted such exclusion.
    
 
    CBCA Section 33-841 applies to the Merger because SNET owns 36.5 percent of
WTC Common Stock. Accordingly, unless the Merger qualifies for exemption, the
Merger must be authorized by the affirmative votes of at least 80 percent of all
of the outstanding shares of WTC Common Stock and two-thirds of the outstanding
shares of WTC Common Stock not held by SNET and its affiliates and associates.
Although the terms of the Merger satisfy the exemption provisions pertaining to
the minimum consideration to be received by WTC shareholders in the transaction,
other requirements for exemption (e.g., the form of consideration) cannot be
satisfied because, among other reasons, the Merger has been structured as a
tax-deferred exchange, and SNET's historic ownership of WTC Common Stock, which
can be traced to a transaction between WTC and SNET in 1910, may not comply with
the technical rules circumscribing share ownership by the interested
shareholder. As a result, the Merger will be prohibited unless authorized by the
affirmative votes in compliance with CBCA Section 33-841. (See "SUMMARY--Vote
Required.")
 
   
    A similar provision of the CBCA prohibits business combinations (defined for
purposes of this provision to include a merger or a consolidation of the
corporation or any subsidiary of the corporation, a sale or other disposition of
assets) having a market value equal to 10 percent or more of the aggregate
market value of all of the outstanding stock of the corporation or representing
10 percent or more of the earning power or net income of the corporation, the
issuance or transfer by the corporation or a subsidiary of the corporation of
stock of such corporation or subsidiary having an aggregate market value equal
to five percent or more of the aggregate market value of all outstanding stock
of the corporation (other than through a pro rata dividend or the exercise of
warrants or other rights or the conversion of convertible securities), the
adoption of a plan or proposal for the complete or partial liquidation of the
corporation or a subsidiary or payment of certain dividends having an aggregate
market value equal to five percent or more of the aggregate market value of the
corporation and proposed by an interested shareholder or an affiliate or an
associate, or any reclassification of securities or merger which has the effect
of increasing the proportionate share of any class or series of voting stock (or
securities convertible into voting stock) owned by the interested shareholder
and is proposed by an interested shareholder or an affiliate or an associate, or
the receipt by the interested shareholder or an affiliate or associate of any
financial benefit from the corporation (other than proportionately as a
shareholder of the corporation) with interested shareholders (which is defined
as a beneficial owner of 10 percent or more of the voting power of the
outstanding shares of voting stock of the corporation, or an affiliate or
associate of the corporation which at any time during the five year period prior
to the transaction was the beneficial owner of 10 percent or more of the voting
power of the then outstanding shares of voting stock of the corporation) within
a five year period after such shareholder became an interested shareholder
unless such business combination is approved by the board of directors and a
majority of the non-employee directors of which there must be at least two,
prior to such interested shareholders' stock acquisition date.
    
 
    The foregoing provision of the CBCA is not applicable to the Merger, as SNET
acquired its share ownership in WTC more than five years prior to the date of
the Merger Agreement.

FIDUCIARY DUTY
 
   
    As permitted under Connecticut law, the SNET Certificate limits in certain
circumstances the monetary liability of directors to SNET and its shareholders
for a breach of their fiduciary duty as directors to the amount of their
compensation for serving SNET as directors during the year of the violation.
These provisions do not eliminate the liability of a director if such breach (i)
involved a knowing and culpable violation of law by the director, (ii) enabled
the director or an associate, as defined in CBCA Section 33-840, to receive an
improper personal economic gain, (iii) showed a lack of good faith and a
conscious disregard for the duty of the director to SNET under circumstances in
which the director was aware his or her conduct or omission created an
unjustifiable risk of serious injury to SNET, (iv) constituted a sustained and
unexecuted pattern of inattention that amounted to an application of the
director's duty to SNET, or (v) created liability under provisions of the CBCA
relating to the distribution of assets of SNET whether by dividend, purchase or
redemption of shares or otherwise in violation of the CBCA. In addition, these
provisions do not eliminate the liability of a director for violation of federal
securities laws, nor do they limit the rights of SNET or its shareholders in
appropriate circumstances to seek equitable remedy such as injunctive or other
forms of non-monetary relief. Such remedies may not be effective in all cases.
    
 
    The WTC Certificate does not contain any limitation for the monetary
liability of directors to WTC and its shareholders for a breach of their
fiduciary duties as directors.
 
   
    Under Connecticut law, a director shall discharge his duties as a director,
including his duties as a member of a committee in good faith, with the care an
ordinarily prudent person in a like position would exercise under similar
circumstances, and in a manner he or she reasonably believes to be in the best
interest of the corporation. In discharging his duties, a director may rely on
information, opinions, reports or statements prepared or presented by corporate
officers or employees whom the director believes to be reliable and competent in
the matters presented, by legal counsel, public accountants and other persons as
to matters the director reasonably believes are within the person's professional
or expert competence, or by a committee of the board of directors of which he is
not a member if the director reasonably believes the committee merits
confidence. In approving a merger, consolidation or sale of all or substantially
all of the assets of a corporation, a director in determining what he reasonably
believes to be in the best interest of the corporation is to consider (i) the
long-term as well as the short-term interests of the corporation, (ii) the
interests of the shareholders, long-term as well as short-term, including the
possibility that those interests may best be served by the continued
independence of the corporation, (iii) the interests of the corporation's
employees, customers, creditors and suppliers, and (iv) community and societal
considerations including those of any community in which any office or other
facility of the corporation is located. A director who so performs those duties
shall be presumed to have no liability by reason of being a director or having
been a director of the corporation.

                          RESALE OF SNET COMMON STOCK
 
    The SNET Common Stock to be issued in the Merger to holders of WTC Common
Stock who are not deemed to be "affiliates" (as defined under the Securities
Act, but generally including directors, certain executive officers and ten
percent or more stockholders) of WTC or SNET may be resold by them under the
Securities Act. It is a condition to consummation of the Merger that each holder
of WTC Common Stock who is deemed by WTC to be an affiliate has entered into an
agreement with SNET providing, among other things, that such affiliate will not
transfer any SNET Common Stock received by such affiliate in the Merger except
in compliance with the Securities Act. This Prospectus/Proxy Statement does not
cover any resales of SNET Common Stock received by affiliates of WTC.
 
                         VALIDITY OF SNET COMMON STOCK
 
    The validity of the SNET Common Stock being offered hereby is being passed
upon for SNET by Madelyn M. DeMatteo, General Counsel of SNET. Ms. DeMatteo is
also a shareholder of SNET and holds options to purchase additional shares of
SNET Common Stock.

dated as of December 6, 1996 among Southern New England Telecommunications
Corporation, a Connecticut corporation ("SNET"), SNET Acquisition Subsidiary,

                                    RECITALS
 
    WHEREAS, the authorized capital stock of WB consists of 1,250,000 shares of
Common Stock par value $2.50 ("WB Common Stock"). As of December 6, 1996,
769,107 shares of WB Common Stock were issued and outstanding, and no shares of
WB Common Stock were issued and held by WB as treasury shares. Each share of WB
Common Stock is entitled to one vote per share;

outstanding and are owned by SNET;
 
    WHEREAS, the authorized capital stock of SNET consists of 300,000,000 shares
of Common Stock, $1.00 par value ("SNET Common Stock"), 2,000,000 shares of
Preferred Stock, $50.00 par value, and 50,000,000 shares of Preference Stock,

were issued and outstanding, 2,758,512 shares were issued and held by SNET as

    WHEREAS, it is intended that the merger of SAS into WB (the "Merger") be
pursuant to the laws of the State of Connecticut and shall qualify as a

amended; and
 
    WHEREAS, the respective Boards of Directors of WB, SAS and SNET deem the
Merger desirable and in the best interests of their respective shareholders and
have duly approved this Agreement and directed that, in the case of WB, this
Agreement be submitted to its shareholders for approval.
 
    NOW, THEREFORE, in consideration of the premises and of the mutual covenants
and agreements herein contained, the parties hereto agree as follows:
 
                                   ARTICLE I
                                   THE MERGER
 
    1.1  THE MERGER: SURVIVING CORPORATION.  In accordance with the provisions
of this Agreement and the Connecticut Business Corporation Act (the "CBCA"), SAS
shall be merged with and into WB, and the separate corporate existence of SAS
shall cease. WB, as the surviving corporation, shall continue to be governed by
the CBCA. SAS and WB are hereinafter referred to as the "Constituent
Corporations," and WB is hereinafter sometimes referred to as the "Surviving
Corporation."
 
    1.2  EFFECTIVE TIME: FILING DATE.  Subject to the provisions of this
Agreement, the certificates of merger required under applicable law (the "Merger
Certificates") shall be filed with the Secretary of the State of Connecticut on
the day of the Closing (as defined in Section 1.3 hereof) or on such other date
as the parties agree. The Merger shall become effective at the time of such
filing with the Secretary of the State of Connecticut (the "Effective Time").
 
    1.3  CLOSING.  The closing (the "Closing") under this Agreement shall be
held at the offices of Day, Berry & Howard, 185 Asylum Street, CityPlace I,
Hartford, Connecticut, or at such other place as the parties agree, at 10:00
A.M. on a date no later than ten days following the receipt of all regulatory
approvals.
 
    1.4  EFFECT OF THE MERGER.  At the Effective Time, the effect of the Merger
shall be as provided under Connecticut law. As of the Effective Time, the
separate existence of SAS shall cease and the corporate existence and identity
of WB shall be a direct wholly-owned subsidiary of SNET.
 
    1.5  FURTHER ASSURANCES.  If at any time after the Effective Time, the
Surviving Corporation shall consider that any deeds, assignments or assurances
in law or any other acts are necessary or desirable (a) to
<PAGE>
vest, perfect or confirm of record or otherwise, in the Surviving Corporation,
its right, interest or title to any property or right of the Constituent
Corporations acquired or to be acquired by reason of, or as a result of, the
Merger, or (b) otherwise to carry out the purposes of this Agreement, the
Constituent Corporations agree that the Surviving Corporation and its officers
and directors may, shall and will execute and deliver in the name and on behalf
of the Constituent Corporations all such property, deeds, assignments and
assurances in law and do all acts necessary or desirable to vest, perfect or
confirm all rights, interest or title to such property or right in the Surviving
Corporation or otherwise to carry out this Agreement.
 
                                   ARTICLE II
                              CONVERSION OF SHARES
 
    The manner and basis of exchanging the shares of WB shall be as follows:
 
    2.1  CONVERSION OF WB COMMON STOCK.
 
    (a) At the Effective Time, SAS will merge with and into WB, by the filing
with the Secretary of the State of Connecticut of the Merger Certificates; and
each share of WB Common Stock issued and outstanding immediately prior to the
Effective Time (other than shares of WB Common Stock owned by SNET), shall, by
virtue of the Merger and without any action on the part of the holder thereof,
be converted into the right to receive, and shall be exchangeable for that
number of shares of SNET Common Stock (including related rights to purchase
shares of SNET Common Stock pursuant to the Rights Agreement, dated as of
December 11, 1996, between SNET and State Street Bank and Trust Company) equal
to the product of one share of SNET Common Stock times a fraction, the numerator
of which is $43.00 and the denominator of which is equal to the average of the
closing prices (the "Average Closing Price") of one share of SNET Common Stock
as reported on the New York Stock Exchange for the ten trading days ending on
the fifth business day prior to the Effective Time (the "Merger Consideration");
PROVIDED that in the event the Average Closing Price is less than $30.00, then
the Merger Consideration shall be determined in accordance with the foregoing
formula based on a deemed Average Closing Price of $30.00 and WB shall have the
option to consummate the Merger based on such deemed Average Closing Price and,
if WB does not opt to do so, then SNET shall have the option to terminate the
Merger pursuant to Article XIII, and in the event the Average Closing Price is
more than $49.00, then the Merger Consideration shall be determined in
accordance with the foregoing formula based on a deemed Average Closing Price of
$49.00 and SNET shall have the option to consummate the Merger based on such
deemed Average Closing Price and, if SNET does not opt to do so, then WB shall
have the option to terminate the Merger pursuant to Article XIII.
 
    (b) At the Effective Time, each share of Sub Common Stock outstanding prior
to the Merger shall be converted into 1,000 shares of the Surviving Corporation,
so that SNET will be the sole and exclusive owner of equity securities of the
Surviving Corporation.
 
    2.2  TREASURY SHARES; SHARES OWNED BY WB OR SNET.  Each share of WB Common
Stock issued and held in the treasury of WB or owned by SNET immediately prior
to the Effective Time shall be canceled, retired and shall cease to exist, and
no right to receive SNET Common Stock shall arise with respect thereto.
 
    2.3  FRACTIONAL SHARES.  No fractional shares of SNET Common Stock shall be
issued in the Merger. In lieu thereof, SNET shall issue to any holder of
certificates of WB Common Stock otherwise entitled to a fractional share, upon
surrender of such certificates in accordance with the instructions furnished by
SNET, a check for an amount of cash equal to the fraction of a share of SNET
Common Stock multiplied by $43.00.
 
    2.4  RIGHTS OF WB SHAREHOLDERS.  The holders of certificates representing
shares of WB Common Stock, other than SNET, shall, by virtue of the Merger,
cease to have rights as shareholders of WB and
 
                                       2
<PAGE>
their sole right shall be the right to receive the Merger Consideration for each
share of WB Common Stock.
 
    2.5  CLOSING OF WB TRANSFER BOOKS.  At the Effective Time, the stock
transfer books of WB shall be closed, and no transfer of shares of capital stock
of WB shall thereafter be made. If, after the Effective Time, certificates
representing shares of WB Common Stock (the "WB Certificates") are presented to
the Surviving Corporation or the Exchange Agent (as defined in Section 2.6) by
shareholders of record of WB Common Stock other than SNET, they shall be
canceled or exchanged for SNET Common Stock and, if required, cash in lieu of
fractional shares as provided in this Article II.
 
    2.6  EXCHANGE OF CERTIFICATES; DIVIDENDS.
 
    (a) At the Effective Time, SNET or SAS shall deposit with State Street Bank
and Trust Transfer Services (the "Exchange Agent"), for the benefit of the
holders of shares of WB Common Stock, certificates representing shares of SNET
Common Stock. The Exchange Agent shall, pursuant to irrevocable instructions,
make the deliveries provided for in Section 2.1 using such SNET Common Stock.
Promptly after the Effective Time, the Exchange Agent shall mail to each WB
shareholder of record (other than SNET) as of immediately prior to the Effective
Time, a form letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the WB Certificates shall pass, only
upon proper delivery of the WB Certificates to the Exchange Agent) and
instructions for use in effecting the surrender of the WB Certificates for
conversion and exchange thereof. Upon surrender to the Exchange Agent of a WB
Certificate, in accordance with the instructions thereto, the holder of such WB
Certificate shall be entitled to receive in exchange therefor SNET Common Stock
allocable to such WB Certificate (and cash in lieu of any fractional share), and
such WB Certificate shall forthwith be canceled. If SNET Common Stock is to be
issued to a person other than the person in whose name the WB Certificate is
registered, it shall be a condition of exchange that the WB Certificate so
surrendered shall be properly endorsed with signatures guaranteed, or otherwise
in proper form for transfer and that the person requesting such payment shall
pay any transfer or other taxes required by reason of the issuance or delivery
to such person or establish to the satisfaction of the Surviving Corporation
that such tax has been paid or is not applicable. Until surrendered in
accordance with this Section 2.6, each WB Certificate shall represent solely the
right to receive the Merger Consideration in the form and manner provided
herein.
 
    (b) No dividends or other distributions that are otherwise payable on such
SNET Common Stock shall be paid to persons entitled to receive such Stock until
such persons surrender their WB Certificates. Upon such surrender, there shall
be paid to such person any dividends which shall have become payable with

been changed into a different number of shares or a different class by reason of
any reclassification, recapitalization, split-up, combination, exchange of
shares or readjustment or similar event, or a stock dividend thereon shall be
declared with a record date within such period, then the number of shares of
SNET Common Stock into which shares of WB Common Stock are to be converted shall
be correspondingly adjusted.
 
    2.8  DISSENTERS' RIGHTS.  Any shareholder of WB demanding dissenters' rights
as provided in CBCA Sections 33-855 to 33-872, inclusive, and who does not
satisfy all requirements for the exercise of dissenters' rights under said
sections of the CBCA, shall be bound by this Agreement in accordance with its

requirements, the shares held by such dissenting shareholder of WB shall
thereupon be treated as though such shares had been converted into the right to
receive the Merger Consideration pursuant to Section 2.1 of this Agreement, and
each WB

indemnification (as in effect as of the date of this Agreement) in any manner
adverse to the Indemnified Parties for a period of three (3) years from and
after the date of this Agreement; provided, however, that such indemnification
is subject to any limitation imposed from time to time under applicable law.
 
    (c) For six (6) years after the Closing, the Surviving Corporation will (and
for so long as it controls the Surviving Corporation, SNET will cause the
Surviving Corporation to) maintain policies of officers' and directors'
liability insurance maintained by WB as of the date of this Agreement (provided
that the Surviving Corporation may substitute therefor policies of at least the
same coverage containing terms and conditions substantially equivalent) with
respect to the acts or omissions occurring before the Effective Time, including
but not limited to the transactions contemplated by this Agreement, covering
each of the Indemnified Parties currently covered by WB's officers' and
directors' liability insurance policy, or who become covered by such policy
before the Effective Time. The provisions of this Section 14.11 shall survive
the Effective Time and shall be enforceable by the Indemnified Parties, their
heirs, executors and personal representatives and are binding on successors and
assigns of WB, SNET and SAS.
 
    (d) Any determination to be made as to whether any Indemnified party has met
any standard of conduct imposed by law or by WB's Certificate of Incorporation
or Bylaws will be made by legal counsel reasonably acceptable to such
Indemnified Party and SNET.
 
    (e) In the event any Indemnified Party is or becomes involved in any
capacity in any action, proceeding, or investigation for which he has a claim
for indemnification against the Surviving Corporation (including, without
limitation, the transactions contemplated by this Agreement), the Surviving
Corporation will, and SNET will (as long as it controls the Surviving
Corporation) cause the Surviving Corporation to, pay as incurred such
Indemnified Party's legal and other expenses actually and reasonably incurred in
connection therewith upon receipt of an understanding by or on behalf of such
Indemnified Party to repay such amount if it is ultimately determined that he is
not entitled to be indemnified by WB. Neither WB, SNET or the Surviving
Corporation shall be liable for any settlement of any claim without its written
consent, which shall not be unreasonably withheld.
 
                                       25
<PAGE>
    (f) Any Indemnified Party wishing to claim indemnification under this
Section 14.11, upon hearing of any claim, action, suit or proceeding or
investigation, shall notify WB, SNET or the Surviving Corporation (but the
failure to so notify an Indemnifying Party shall not relieve it from any
liability it may have under this Section, except to the extent such failure
prejudices such party). The Indemnified Parties as a group may retain only one
law firm to represent them with respect to such matter unless there is, under
applicable standards of conduct, a conflict on any significant issue between the
parties of any two or more Indemnified Parties.
 
    (g) The obligations pursuant to this Section 14.11 will survive the Merger
and will continue in full force and effect for a period of three (3) years from
the Effective Time (except that the obligations of the Surviving Corporation
pursuant to subsection (c) of this Section to maintain policies of officers' and
directors' liability insurance shall continue for six (6) years and the
obligations of the Surviving Corporation and SNET pursuant to subsection (a) of
this Section shall continue for such six-year period solely with respect to
matters covered by such policies), provided that as to any claim for
indemnification asserted pursuant to this Section 14.11 during such three-year
or six-year period, as applicable, such obligations will remain in full force
and effect until the final disposition of such claim.

Ladies and Gentlemen:

    You have requested our opinion as to the fairness, from a financial point
of view, of the Merger Consideration (as defined herein) to be paid by Southern
New England Telecommunications Corporation ("SNET") to the holders of the issued
and outstanding shares of Common Stock, $2.50 par value (the "Common Stock") of
The Woodbury Telephone Company (the "Company") in connection with the proposed
merger (the "Merger") of the Company with and into SNET Acquisition Company,
Inc. ("SAS"), a wholly owned subsidiary of SNET, pursuant to the Amended and
Restated Agreement and Plans of Merger dated as of December 6k, 1996 (the
"Agreement") by and among the Company, SNET and SAS.

    Under the terms of the Agreement, SAS will be merged with and into the
Company and the Company will become a wholly-owned subsidiary of SNET.  AT the
effective time of the Merger (the "Effective Time"), each issued and outstanding
share of the Company's Common Stock (other than shares owned by SNET, shares
held in treasury and shares as to which dissenters' rights of appraisal have
been perfected) will be converted into the right to receive shares of SNET
Common Stock in an amount per share equal to the product of one share of SNET
Common Stock times a fraction, the numerator of which is $43.00 per share and
the denominator of which is equal to the average of the closing prices of one
share of SNET Common Stock as reported o the New York Stock Exchange for the ten
trading days ending on the fifth business day prior to the Effective Time (the
"Merger Consideration").

    McDonald & Company Securities, Inc., as part of its investment banking
business, is customarily engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for estate, corporate and

    In connection with rendering his opinion, we have reviewed and analyzed,
among other things, the following: (I) the Agreement, including the exhibits and
schedules thereto; (ii) certain correspondence between the Company and SNET and
between the Company and other prospective buyers (iii) certain publicly
available information concerning the Company, including the Company's audited
financial results for the three year period ending December 31, 1996 as reported
in the Annual Reports on Form 10-K of the Company for each of the years in the
two year period ended December 31, 1996 and the Quarterly Reports on Form 10-Q
of the Company for each of the three quarters in the period ended September 30,
1996; (iv) certain other internal information, primarily financial in nature,
including projections, concerning the business and operations of the Company
furnished to us by the Company for purposes of our analysis; (v) certain
publicly available information concerning the trading of, and the trading market
for the Company's Common Stock and the SNET Common Stock; (vi) certain publicly
available information with respect to certain other companies that we believe to
be comparable to the Company or to SNET and the trading markets for certain of
such other comp[companies'' securities; and (vii) certain publicly available
information concerning the nature and terms of certain other transactions that
we consider relevant to our inquiry.  We have also met with certain officers and
employees of the Company to discuss  the prospects of the Company, as well as
other matters we believe relevant to our inquiry.  In addition, we have
participated in discussions with certain officers and employees of SNET to
assess the business prospects of SNET.

    In our review and analysis and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and other
information provided us or publicly available and have assumed and relied upon
the representations and warranties of the Company and SNET contained in the
Agreement.  We have not been engaged to, and have not independently attempted
to, verify any of such information.  We have also relied upon the management for
the Company as to the reasonableness and achievability of the financial and
operating projections (and the assumptions and bass therefor) provided to us
and, with your consent, we have assumed that such projections reflect the best
currently available estimates and judgments of the Company's management and that
such projections and forecast will be realized in the amounts and in the time
periods currently estimated by the management of the Company.  With respect to
SNET, we have assumed that the assumptions underlying published third party
earnings estimates for SNET are reasonable and that such earnings will be
realized in the amounts and in the time periods contemplated thereby.  We have
not been engaged to assess the achievability of such projections or the
assumptions on which they were based and express no view as to such projections
or assumptions.  In addition, we have not conducted a physical inspection or
appraisal of any of the assets, properties or facilities of either the Company
or SNET nor have we been furnished with any such evaluation or appraisal. We
have also assumed

that; (I) the conditions to the Merger as set forth in the Agreement would be
satisfied; (ii) that the Merger would be consummated on a timely basis in the
manner contemplated by the Agreement;' and (iii) that the Merger will qualify as
a tax-free reorganization under applicable provisions of the Internal Revenue
Code.

    Based upon discussions with the Company and its counsel, McDonald has
assumed for the purpose of its analysis that, under applicable provisions of
Connecticut law and the Company's charter documents, SNET's ownership of shares
representing more than one-third of the voting power of the Company gives it the
ability to block the sale of all or substantially all of the assets of the
Company to any other party or the merger of the Company with another party. 

    It should be noted that this opinion is based on economic and market
conditions and other circumstances existing on, and information made available
as of, the date hereof and does not address any matters subsequent to such date
including the value of the SNET Common Stock at the time of issuance thereof to
the holders of the Company's Common Stock.  In addition, our opinion is, in any
event, limited to the fairness, as of the date hereof, from a financial point of
view, of the Merger Consideration to be received by the holders of the Company
Common Stock pursuant to the Merger and does not address the Company's
underlying business decision to effect the Merger or any other terms of the
Merger.

    in the ordinary course of our business, we may actively  trade securities
of both the Company and SNET for our own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.

    McDonald will receive a fee from the Company for our services, in rendering
this opinion, non e of which is contingent upon the consummation of the Merger,
as well as the Company's agreement to indemnify us under certain circumstances.

    It is understood that this opinion was prepared solely for the confidential
use of the Board of Directors and senior management of the Company and may not
be disclosed, summarized, excerpted from or otherwise publicly referred to
without our prior written consent.  Our opinion does not constitute a
recommendation to any stockholder of the Company as to how such stockholder
should vote at the stockholders' meeting held in connection with the Merger.

    Based upon and subject to the foregoing and such other matters as we
consider relevant, it is our opinion that as of the date hereof, the Merger
Consideration to be received by the holders of Common Stock pursuant to the
Agreement is fair, from a financial point of view, to the holders of such Common
Stock.

                        Very truly yours,

    (a) A shareholder is entitled to dissent from, and obtain payment of the
fair value of his shares in the event of, any of the following corporate
actions:
 
   
    (1) Consummation of a plan of merger to which the corporation is a party (A)

beneficially owned by any one person and notifies the corporation in writing of

    (2) The corporation fails to make payment under section 33-865 within sixty
days after the date set for demanding payment; or
 
    (3) The corporation, having failed to take the proposed action, does not
return the deposited certificates or release the transfer restrictions imposed
on uncertificated shares within sixty days after the date set for demanding
payment.
 
    (b) A dissenter waives his right to demand payment under this section unless
he notifies the corporation of his demand in writing under subsection (a) of
this section within thirty days after the corporation made or offered payment
for his shares.
 
   
SECTIONSECTION 33-869, 33-870. RESERVED FOR FUTURE USE
    
 
                        (C) JUDICIAL APPRAISAL OF SHARES
 
SECTION 33-871. COURT ACTION
 
    (a) If a demand for payment under section 33-868 remains unsettled, the
corporation shall commence a proceeding within sixty days after receiving the
payment demand and, petition the court to determine the fair value of the shares
and accrued interest. If the corporation does not commence the
 
                                       4
<PAGE>
proceeding within the sixty-day period, it shall pay each dissenter whose demand
remains unsettled the amount demanded.
 
    (b) The corporation shall commence the proceeding in the superior court for
the judicial district where a corporation's principal office or, if none in this
state, its registered office is located. If the corporation is a foreign
corporation without a registered office in this state, it shall commence the
proceeding in the superior court for the judicial district where the registered
office of the domestic corporation merged with or whose shares were acquired by
the foreign corporation was located.
 
   
    (c) The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unsettled parties to the proceeding as in an
action against their shares and all parties must be served with a copy of the
petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.
    
 
    (d) The jurisdiction of the court in which the proceeding is commenced under
subsection (b) of this section is plenary and exclusive. The court may appoint
one or more persons as appraisers to receive evidence and recommend decision on
the question of fair value. The appraisers have the powers described in the
order appointing them, or in any amendment to it. The dissenters are entitled to
the same discovery rights as parties in other civil proceedings.
 
    (e) Each dissenter made a party to the proceeding is entitled to judgment
(1) for the amount, if any, by which the court finds the fair value of his
shares, plus interest, exceeds the amount paid by the corporation, or (2) for
the fair value, plus accrued interest, of his after-acquired shares for which
the corporation elected to withhold payment under section 33-867.
 
SECTION 33-872. COURT COSTS AND COUNSEL FEES
 
    (a) The court in an appraisal proceeding commenced under section 33-871
shall determine all costs of the proceeding, including the reasonable
compensation and expenses of appraisers appointed by the court. The court shall
assess the costs against the corporation, except that the court may assess costs
against all or some of the dissenters, in amounts the court finds equitable, to
the extent the court finds the dissenters acted arbitrarily, vexatiously or not
in good faith in demanding payment under section 33-868.
 
    (b) The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable: (1) Against
the corporation and in favor of any or all dissenters if the court finds the
corporation did not substantially comply with the requirements of sections
33-860 to 33-868, inclusive; or (2) against either the corporation or a
dissenter, in favor of any other party, if the court finds that the party
against whom the fees and expenses are assessed acted arbitrarily, vexatiously
or not in good faith with respect to the rights provided by sections 33-855 to
33-872, inclusive.
 
   
    (c) If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the corporation, the court may
award to these counsel reasonable fees to be paid out of the amounts awarded the
dissenters who were benefited.

                             March 10, 1997



The Woodbury Telephone Company
299 Main Street South
Woodbury, Connecticut 06798

Ladies and Gentlemen:

    We have acted as counsel to The Woodbury Telephone Company, a Connecticut
corporation ("WTC"), in connection with the proposed merger (the "Merger") set
forth in the Amended and Restated Agreement and Plan of Merger dated December 6,
1996 (the "Merger Agreement"), among WTC, Southern New England
Telecommunications Corporation ("SNET") and SNET Acquisition Subsidiary, Inc.
("SAS"), a wholly-owned subsidiary of SNET.  Pursuant to the Merger Agreement,
SAS will merge into WTC and WTC will become a wholly-owned subsidiary of SNET.  

   
    Capitalized terms used but not defined herein shall have the meanings
specified in the Prospectus/Proxy Statement.
                                      
    We are rendering our opinion at your request concerning certain federal 
income tax consequences of the Merger and in connection with the filing by 
SNET of the Registration Statement on Form S-4 filed with the Securities and 
Exchange Commission on March 5, 1997 (the "Registration Statement") in 
respect of the shares of SNET Common Stock to be issued in the Merger and the 
preliminary Prospectus/Proxy Statement of SNET and WTC (the "Prospectus/Proxy 
Statement") included as part thereof. 

    For purposes of the opinion set forth below, we have relied upon the 
following assumptions: (i) the Merger will be consummated in accordance with 
the Merger Agreement; (ii) the representations made by WTC, SNET, and SAS in 
the Merger Agreement are accurate, as of the Effective Time; (iii) the 
representations in the Prospectus/Proxy Statement are accurate; (iv) the only 
authorized, issued, and outstanding class of the capital stock of WTC is WTC 
Common Stock; and WTC Common  Stock is entitled to vote for the election of
directors and on all other matters requiring a vote of shareholders; (v) SNET
presently has no plan or intention  to liquidate WTC, to merge WTC with another
corporation (other than SAS), to  sell or otherwise dispose of the capital
stock of WTC, or to cause WTC to issue additional shares of its capital stock
that would  
    

<PAGE>

The Woodbury Telephone Company

Page 2
   
result in loss of "control" as defined under Section 368(c) of the Internal
Revenue Code of 1986, as amended (the "Code"); (vi) SNET currently has no plan
or intention to cause WTC to sell or dispose of any of its assets to the extent
that such disposition or dispositions would cause the Merger to fail to satisfy
the "Continuity of Business Enterprise" requirements as a result of a failure
by SNET to continue WTC's historic line of business or otherwise fail to use a
significant portion of WTC's historic business assets; (vii) as of the
Effective Time, no event has occurred under the Rights Plan, which would make
the SNET Rights exercisable, or transferable, apart from the SNET Common Stock,
and SNET has not exercised any right of redemption under the Rights Plan; and
(viii) following the Merger, after taking dissenters' rights of WTC
shareholders under Connecticut law into account, and provided that all
consideration paid to dissenting shareholders is paid by WTC from its own
pre-Merger assets, SNET will own 80% or more of the outstanding shares of WTC
Common Stock.    
    

    We have also assumed that the transactions contemplated by the Merger
Agreement will qualify as a statutory merger under the applicable laws of the
State of Connecticut.

    Based upon and subject to the foregoing, it is our opinion that, under
currently applicable law, the Merger will constitute a reorganization within the
meaning of Section 368 of the Code and that, accordingly, the following will be
the material federal income tax consequence of the Merger:

   
    (i)  No gain or loss will be recognized for federal income tax purposes by
    the shareholders of WTC on the exchange of their shares of WTC Common Stock
    solely for shares of SNET Common Stock, except with respect to cash
    received in lieu of a fractional share interest in SNET Common Stock,
    pursuant to the terms of the Merger Agreement.
    

    (ii)  The federal income tax basis of the shares of SNET Common Stock
    received in the Merger by WTC shareholders (including the basis allocable
    to any fractional interest in any share of SNET Common Stock) will be the
    same as 

<PAGE>

The Woodbury Telephone Company
March 10, 1997
Page 3


    the basis of such shares of WTC Common Stock exchanged therefor.

    (iii)  The holding period for shares of SNET Common Stock for which shares
    of WTC Common Stock are exchanged (including the holding period of any
    fractional share interest in SNET Common Stock) will include the period
    that such shares of WTC Common Stock were held by the holder, provided such
    shares were a capital asset of the holder.

    (iv)  The receipt of cash in lieu of fractional shares of SNET Common Stock
    by a WTC shareholder will be treated as received for such fractional share
    interest and, provided the fractional share would have constituted a
    capital asset in the hands of such holder, the holder should in general
    recognize capital gain or loss in an amount equal to the difference between
    the amount of cash received and the portion of the adjusted tax basis in
    the WTC Common Stock allocable to the fractional share interest.

   
    This opinion may not be applicable to WTC shareholders who received their
WTC Common Stock pursuant to the exercise of employee stock options or otherwise
as compensation, that hold WTC Common Stock as part of a "straddle" or
"conversion transaction," or that are insurance companies, securities dealers,
financial institutions or who are not citizens or residents of the United
States.  Further, this opinion does not address the effect of any exercise,
transfer or redemption of SNET Rights upon the occurrence of a triggering event
following the Effective Time.
    

    There can be no assurance that the Internal Revenue Service will not take a
contrary view to those expressed herein.  Moreover, legislative, judicial, or
administrative changes or interpretations may be forthcoming that could alter or
modify the statements and conclusions set forth herein.  Any such changes or
interpretations may or may not be retroactive and could possibly affect the tax
consequences to WTC shareholders.
