            AT&T Corp. hereby amends the Schedule 13D (as previously amended,
the "Schedule 13D") originally filed on October 13, 1998 and amended on November
9, 1998 as set forth herein. Capitalized terms used without definition in this
Amendment No. 2 to the Schedule 13D shall have the respective meanings ascribed
thereto in the Schedule 13D.



ITEM 4.     PURPOSE OF TRANSACTION.

            Item 4 of the Schedule 13D is hereby amended by adding the
following:

            AT&T, Merger Sub and Vanguard entered into the Amended and Restated
Agreement and Plan of Merger, dated as of October 2, 1998. The Amended and
Restated Agreement and Plan of Merger amends and restates the Merger Agreement
to (i) incorporate the amendments provided in Amendment No. 1, (ii) provide that
the condition to the Merger regarding the receipt of tax opinions be
non-waivable and (iii) make certain other procedural and clarificatory
amendments to the Merger Agreement regarding the closing of the Merger, the
deadline for submitting an election with respect to the form of payment to be
received by holders of shares of Vanguard Common Stock in the Merger and
dissenters' shares.

            The foregoing summary of the Amended and Restated Agreement and Plan
of Merger does not purport to be complete and is qualified in its entirety by
reference to the Amended and Restated Agreement and Plan of Merger, which is
attached as Exhibit 5 hereto and is incorporated herein by reference. References
hereafter to the "Merger Agreement" shall be references to such Amended and
Restated Agreement and Plan of Merger.

            On December 28, 1998, AT&T consented under the Merger Agreement to
the lending by Vanguard to certain of its executive officers (the "Executive
Loan Program") of funds which will be used by such executive officers to finance
the exercise of stock options to purchase up to an aggregate of 4,398,795 shares
of Vanguard Common Stock (1,580,045 of which are held by executive officers not
parties to Voting Agreements) and to satisfy certain related tax obligations,
provided that any such loan will be secured by the shares of Vanguard Common
Stock purchased thereby and by certain other payments to be made to such
executive officers in connection with the Merger. In connection with such
borrowing, such officers not parties to Voting Agreements will be required to
agree (i) to vote the shares of Vanguard Common Stock acquired in connection
therewith in favor of approval of the Merger Agreement and against any
Acquisition Proposal from any person other than AT&T and (ii) not to sell,
transfer, dispose of, encumber or otherwise convey any interest in such shares
prior to March 31, 1999. Such officers who are parties to Voting Agreements will
continue to be subject to such Voting Agreements.

            The foregoing summary of the Executive Loan Program does not purport
to be complete and is qualified in its entirety by reference to the documents
which are attached as Exhibit 6 hereto and are incorporated herein by reference.

            On December 22, 1998, AT&T consented under the Merger Agreement to
the transfers of 784,782 shares of Vanguard Common Stock, which shares are
subject to the Voting Agreements, by Haynes G. Griffin, Stephen R. Leeolou and
L. Richardson Preyer, Jr. to The Haynes G. Griffin 1998 Charitable Remainder
Unitrust, the Griffin Family Foundation, The 


                                       3
<PAGE>

Stephen R. and Mary D. Leeolou 1998 Charitable Remainder Unitrust, the Leeolou
Family Foundation, the Lunsford Richardson Preyer, Jr. Charitable Remainder
Unitrust and the Preyer-Jacobs Foundation (the "Charitable Trust and Family
Foundation Stockholders"). In connection therewith, the Charitable Trust and
Family Foundation Stockholders entered into voting agreements (the "Charitable
Trust and Family Foundation Voting Agreements") on terms substantially the same
as the Voting Agreements, including granting to AT&T an option to purchase
transferred shares under the applicable Charitable Trust and Family Foundation
Voting Agreement (such options to purchase, collectively, the "Charitable Trust
and Family Foundation Stockholders' Options").

            The foregoing summary of the Charitable Trust and Family Foundation
Agreements does not purport to be complete and is qualified in its entirety by
reference to the Charitable Trust and Family Foundation Agreements, which are
attached as Exhibit 7 hereto and are incorporated herein by reference.


ITEM 5.     INTEREST IN SECURITIES OF THE ISSUER.

            Item 5 of the Schedule 13D is hereby amended by adding the
following:

            Prior to the Charitable Trust and Family Foundation Stockholders'
Options becoming exercisable and being exercised, AT&T expressly disclaims
beneficial ownership of the shares of Vanguard Common Stock which may be
purchasable by AT&T thereunder. AT&T also expressly disclaims beneficial
ownership of the shares of Vanguard Common Stock subject to the Voting
Agreements, the shares of Vanguard Common Stock subject to the Charitable Trust
and Family Foundation Voting Agreements and the 1,580,045 shares of Vanguard
Common Stock which may be purchased pursuant to the Executive Loan Program by
executive officers not subject to Voting Agreements as described in Item 4.
Neither the filing of the Schedule 13D nor the filing of this Amendment #2 to
the Schedule 13D nor any of their contents shall be deemed to constitute an
admission that AT&T is the beneficial owner of the shares of Vanguard Common
Stock subject to the Vanguard Option, the Stockholders' Options, the Charitable
Trust and Family Foundation Stockholders' Options, the Voting Agreements or the
Charitable Trust and Family Foundation Voting Agreements or any shares of
Vanguard Common Stock purchased pursuant to the Executive Loan Program for
purposes of Section 13(d) or 16 of the Securities Exchange Act of 1934, as
amended, or for any other purpose and such beneficial ownership is expressly
disclaimed.

a) The Charitable Trust and Family Foundation Stockholders' Options are
   substantially similar to the Stockholders' Options. Based on the number of
   outstanding shares of Vanguard Common Stock on June 30, 1998, if the Vanguard
   Option, the Stockholders' Options and the Charitable Trust and Family
   Foundation Stockholders' Options were exercised in full, AT&T would
   beneficially own 28.0% of the shares of Vanguard Common Stock outstanding
   following exercise of the Vanguard Option, each of the Stockholder's Options
   and each of the Charitable Trust and Family Foundation Stockholders' Options.
   If AT&T were also to beneficially own the 1,580,045 shares of Vanguard Common
   Stock which may be purchased pursuant to the Executive Loan Program by
   executives of Vanguard not subject to Voting Agreements as described in Item
   4, AT&T would beneficially own, in total, 30.5% of the shares of Vanguard
   Common Stock outstanding.


                                       4
<PAGE>

b) AT&T would have sole voting and dispositive power with respect to any shares
   of Vanguard Common Stock acquired upon exercise of the Vanguard Option and/or
   the Stockholders' Options and/or the Charitable Trust and Family Foundation
   Stockholders' Options.

d) Except as described in Item 4 above, until the Vanguard Option and/or any
   Stockholder's Option and/or any Charitable Trust and Family Foundation
   Stockholders' Option is exercised, AT&T has no right to receive dividends
   from, or the proceeds from the sale of, the shares of Vanguard Common Stock
   subject to the Vanguard Option and the Stockholders' Options. If the Vanguard
   Option and/or any Stockholder's Option and/or any Charitable Trust and Family
   Foundation Stockholders' Option were exercised by AT&T, AT&T would have the
   sole right to receive dividends on the shares of Vanguard Common Stock
   acquired pursuant thereto.

       5.  Amended and Restated Merger Agreement and Plan of Merger dated

<PAGE>

   NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, and
intending to be legally bound hereby, the parties hereto agree as follows:

                                   ARTICLE I.

                                 PLAN OF MERGER

   1.1 The Merger. In accordance with the North Carolina Business Corporation
Act (the "NCBCA") and the Delaware General Corporation Law (the "DGCL"), the
Company shall be merged with and into Winston, Inc., a Delaware corporation and
wholly owned subsidiary of Parent ("Merger Sub") (the "Merger"). Following the
Merger, the separate corporate existence of the Company shall cease and Merger
Sub shall continue as the surviving corporation (the "Surviving Corporation") in
accordance with Section 55-11-07 of the NCBCA and Section 252 of the DGCL.

   1.2 Effective Time. The Merger shall become effective when (i) articles of
merger (the "Articles of Merger") are filed with the Secretary of State of North
Carolina in such form as is required by and executed in accordance with Section
55-11-05 of the NCBCA and a certificate of merger (a "Certificate of Merger") is
filed with the Secretary of State of Delaware in accordance with Sections 251
and 252 of the DGCL or (ii) such other time as Parent and the Company shall
agree in writing should be specified in the Articles of Merger (the date and
time the Merger becomes effective being the "Effective Time").

   1.3 Effects of the Merger. At and after the Effective Time, the Merger will
have the effects set forth in Section 55-11-06 of the NCBCA and Section 259 of
the DGCL. Without limiting the generality of the foregoing, and subject thereto,
at the Effective Time all the property, rights, privileges, powers and
franchises of the Company and Merger Sub shall be vested in the Surviving
Corporation, and all debts, liabilities and duties of the Company and Merger Sub
shall become the debts, liabilities and duties of the Surviving Corporation.

   1.4 Certificate of Incorporation. The certificate of incorporation of Merger
Sub in effect immediately prior to the Effective Time shall be the certificate
of incorporation of the Surviving Corporation until thereafter changed or
amended as provided therein or by applicable law.

   1.5 By-Laws. The by-laws of Merger Sub in effect at the Effective Time shall
be the by-laws of the Surviving Corporation until thereafter changed or amended
as provided therein or by applicable law.

   1.6 Directors and Officers of Surviving Corporation. The directors and
officers of Merger Sub shall be the directors and officers, respectively, of the
Surviving Corporation, until the earlier of their resignation or removal or
otherwise ceasing to be a director or officer, as the case may be, or until
their respective successors are duly elected and qualified, as the case may be.

   1.7 Effect on Capital Stock. As of the Effective Time, by virtue of the
Merger and without any action on the part of the holders of any shares of the
Company's Class A Company Common Stock, par value $.01 per share (the "Company
Common Stock"):

     (a) Cancellation of Stock. Each share of Company Common Stock that is owned
   by the Company or any wholly owned subsidiary of the Company (as treasury
   stock or otherwise) shall automatically be canceled and retired and shall
   cease to exist and no consideration shall be delivered in exchange therefor.

     (b) Consideration for Company Common Stock. Subject to Section 1.11, each
   issued and outstanding share of Company Common Stock (other than Dissenting
   Shares and shares to be canceled in accordance with Section 1.7(a)) shall be
   converted into either (i) the right to 

                                      -2-

   receive 0.3987 fully paid and nonassessable shares of common stock, par value
   $1.00 per share, of Parent ("Parent Common Stock") (the "Per Share Stock
   Amount"), or (ii) the right to receive $23.00 in cash, without interest (the
   "Per Share Cash Amount"), or (iii) a combination of shares of Parent Common
   Stock and cash, each as determined in accordance with Section 1.7(f), Section
   1.7(g) or Section 1.7(h). As of the Effective Time, all such shares of
   Company Common Stock shall no longer be outstanding and shall automatically
   be canceled and retired and shall cease to exist, and each holder of a
   certificate representing any such shares of Company Common Stock shall cease
   to have any rights with respect thereto, except the right to receive, upon
   surrender of such certificate in accordance with Section 2.3, the Per Share
   Stock Amount, the Per Share Cash Amount or a combination of cash and Parent
   Common Stock, each in accordance with this Section 1.7. The consideration to
   be received in the Merger under this Article for one share of Company Common
   Stock shall be referred to herein as the "Merger Consideration."

     (c) Merger Sub Capital Stock. Each share of capital stock of Merger Sub
   issued and outstanding immediately prior to the Effective Time shall remain
   outstanding and shall be unchanged as a share of capital stock of the
   Surviving Corporation.

     (d) The aggregate number of shares of Company Common Stock which may be
   converted into the right to receive cash in the Merger shall be equal to 50%
   of the number of shares of Company Common Stock outstanding immediately prior
   to the Effective Time (other than Dissenting Shares and shares to be
   canceled in accordance with Section 1.7(a)). The aggregate number of shares
   of Company Common Stock which may be converted into the right to receive
   Parent Common Stock in the Merger shall be equal to 50% of the number of
   shares of Company Common Stock outstanding immediately prior to the Effective
   Time (other than Dissenting Shares and shares to be canceled in accordance
   with Section 1.7(a)).

     (e) Subject to the allocation and election procedures set forth in this
   Section 1.7 (which allocation procedures shall be calculated as of
   immediately prior to the Effective Time), each record holder (or beneficial
   owner through appropriate and customary documentation and instructions)
   immediately prior to the Effective Time of shares of Company Common Stock
   shall be entitled either (i) to elect to receive the Per Share Cash Amount
   for each such share of Company Common Stock (a "Cash Election"), or (ii) to
   elect to receive the Per Share Stock Amount for each such share of Company
   Common Stock (a "Stock Election"), or (iii) to indicate that such record
   holder has no preference as to the receipt of cash, Parent Common Stock or a
   combination thereof with respect to such holder's shares of Company Common
   Stock (a "Non-Election", and any Cash Election, Stock Election or
   Non-Election shall be referred to herein as an "Election"); provided,
   however, that no holder of Dissenting Shares shall be entitled to make an
   Election. All such elections shall be made on a form furnished by Parent for
   that purpose (a "Form of Election") and reasonably satisfactory to the
   Company. If more than one certificate which immediately prior to the
   Effective Time represented outstanding shares of Company Common Stock (a
   "Certificate") shall be surrendered for the account of the same holder, the
   number of shares of Parent Common Stock, if any, to be issued to such holder
   in exchange for the Certificates which have been surrendered shall be
   computed on the basis of the aggregate number of shares of Company Common
   Stock represented by all of the Certificates surrendered for the account of
   such holder. Holders of record of shares of Company Common Stock who hold
   such shares of Company Common Stock as nominees, trustees or in other
   representative capacities (each, a "Representative") may submit multiple
   Forms of Election, provided that such Representative certifies that each such
   Form of Election covers all shares of Company Common Stock held by such
   Representative for a particular beneficial owner.

     (f) If the aggregate number of shares of Company Common Stock with respect
   to which Cash Elections have been made exceeds the aggregate number of shares
   of Company Common Stock which may be converted into the right to receive cash
   in the Merger, then:

     A. Each share of Company Common Stock with respect to which a Stock
   Election shall have been made shall be converted into the right to receive
   the Per Share Stock Amount;

     B. Each share of Company Common Stock with respect to which a Non-Election
   shall have been made (or deemed to have been made) shall be converted into
   the right to receive the Per Share Stock Amount; and

     C. Each share of Company Common Stock with respect to which a Cash Election
   shall have been made shall be converted into the right to receive:

     (1) the amount in cash, without interest, equal to the product of (i) the
   Per Share Cash Amount and (ii) a fraction (the "Cash Fraction"), the
   numerator of which shall be the aggregate number of shares of Company Common
   Stock which may be converted into the right to receive cash in the Merger,
   and the denominator of which shall be the aggregate number of shares of
   Company Common Stock with respect to which Cash Elections shall have been
   made, and

     (2) the number of shares of Parent Common Stock equal to the product of (x)
   the Per Share Stock Amount and (y) a fraction equal to one minus the Cash
   Fraction.

     (g) If the aggregate number of shares of Company Common Stock with respect
   to which Stock Elections have been made exceeds the aggregate number of
   shares of Company Common Stock which may be converted into the right to
   receive Parent Common Stock in the Merger, then:

     A. Each share of Company Common Stock with respect to which a Cash Election
   shall have been made shall be converted into the right to receive the Per
   Share Cash Amount;

     B. Each share of Company Common Stock with respect to which a Non-Election
   shall have been made (or deemed to have been made) shall be converted into
   the right to receive the Per Share Cash Amount; and

     C. Each share of Company Common Stock with respect to which a Stock
   Election shall have been made shall be converted into the right to receive:

     (1) the number of shares of Parent Common Stock equal to the product of (i)
   the Per Share Stock Amount and (ii) a fraction (the "Stock Fraction"), the
   numerator of which shall be the aggregate number of shares of Company Common
   Stock which may be converted into the right to receive Parent Common Stock in
   the Merger, and the denominator of which shall be the aggregate number of
   shares of Company Common Stock with respect to which Stock Elections shall
   have been made, and

     (2) the amount in cash, without interest, equal to the product of (x) the
   Per Share Cash Amount and (y) a fraction equal to one minus the Stock
   Fraction.

     (h) In the event that neither  Section 1.7(f) nor Section 1.7(g) above is
   applicable, then:

     A. Each share of Company Common Stock with respect to which a Cash Election
   shall have been made (or deemed to have been made) shall be converted into
   the right to receive the Per Share Cash Amount;

                                      -4-
<PAGE>

       B. Each share of Company Common Stock with respect to which a Stock
   Election shall have been made (or deemed to have been made) shall be
   converted into the right to receive the Per Share Stock Amount; and

       C. Each share of Company Common Stock with respect to which a
   Non-Election shall have been made (or deemed to have been made), if any,
   shall be converted into the right to receive:

           (1) the amount in cash, without interest, equal to the product of (i)
       the Per Share Cash Amount and (ii) a fraction (the "Non-Election
       Fraction"), the numerator of which shall be the excess of the (A)
       aggregate number of shares of Company Common Stock which may be converted
       into the right to receive cash in the Merger over (B) the sum of the
       aggregate number of shares of Company Common Stock with respect to which
       a Cash Election shall have been made, and the denominator of which shall
       be the excess of (A) the aggregate number of shares of Company Common
       Stock outstanding immediately prior to the Effective Time (other than
       shares to be canceled in accordance with Section 1.7(a)) over (B) the
       sum of the aggregate number of shares of Company Common Stock with
       respect to which a Cash Election and a Stock Election shall have been
       made plus Dissenting Shares, and

   (2)the number of shares of Parent Common Stock equal to the product of (x)
      the Per Share Stock Amount and (y) a fraction equal to one minus the
      Non-Election Fraction.

     (i) Elections shall be made by holders of shares of Company Common Stock by
   delivering the Form of Election to the exchange agent. To be effective, a
   Form of Election must be properly completed, signed and submitted to the
   Exchange Agent by no later than 5:00 p.m. (New York City time) on the last
   business day prior to the Company Shareholders Meeting, if the Effective Time
   is reasonably expected by the Company and Parent to occur at least three but
   no more than five business days following such Company Shareholders Meeting
   (the "Election Deadline") (provided that if the Effective Time is not
   reasonably expected to occur at least three but no more than five business
   days following the Company Shareholders Meeting, Parent and the Company shall
   agree to a later date and time, reasonably expected to be at least four
   business days prior to the Effective Time as the Election Deadline (and shall
   reset such date if necessary so that the Election Deadline is at least three
   business days before the Effective Time) and shall publish appropriate
   advance notice of such Election Deadline), and accompanied by (1)(x) the
   Certificates representing the shares of Company Common Stock as to which the
   election is being made or (y) an appropriate guarantee of delivery of such
   Certificates as set forth in such Form of Election from a firm which is a
   member of a registered national securities exchange or of the National
   Association of Securities Dealers, Inc. or a commercial bank or trust company
   having an office or correspondent in the United States, provided such
   Certificates are in fact delivered to the Exchange Agent within three New
   York Stock Exchange ("NYSE") trading days after the date of execution of such
   guarantee of delivery (a "Guarantee of Delivery"), and (2) a properly
   completed and signed letter of transmittal. Failure to deliver Certificates
   covered by any Guarantee of Delivery within three NYSE trading days after the
   date of execution of such Guarantee of Delivery shall be deemed to invalidate
   any otherwise properly made Cash Election or Stock Election. Parent will have
   the discretion, which it may delegate in whole or in part to the Exchange
   Agent, to determine whether Forms of Election have been properly completed,
   signed and submitted or revoked and to disregard immaterial defects in Forms
   of Election. The good faith decision of Parent (or the Exchange Agent) in
   such matters shall be conclusive and binding. Neither Parent nor the Exchange
   Agent will be under any

                                      -5-
<PAGE>
 
   obligation to notify any person of any defect in a Form of Election submitted
   to the Exchange Agent. A Form of Election with respect to Dissenting Shares
   shall not be valid. The Exchange Agent shall also make all computations
   contemplated by this Section 1.7 and all such computations shall be
   conclusive and binding on the holders of shares of Company Common Stock in
   the absence of manifest error. Any Form of Election may be changed or revoked
   prior to the Election Deadline. In the event a Form of Election is revoked
   prior to the Election Deadline, Parent shall, or shall cause the Exchange
   Agent to, cause the Certificates representing the shares of Company Common
   Stock covered by such Form of Election to be promptly returned without charge
   to the person submitting the Form of Election upon written request to that
   effect from such person.

     (j) For the purposes hereof, a holder of shares of Company Common Stock who
   does not submit a Form of Election which is received by the Exchange Agent
   prior to the Election Deadline (including a holder who submits and then
   revokes his or her Form of Election and does not resubmit a Form of Election
   which is timely received by the Exchange Agent), or who submits a Form of
   Election without the corresponding Certificates or a Guarantee of Delivery,
   shall be deemed to have made a Non-Election. If any Form of Election is
   defective in any manner such that the Exchange Agent cannot reasonably
   determine the election preference of the shareholder submitting such Form of
   Election, the purported Cash Election or Stock Election set forth therein
   shall be deemed to be of no force and effect and the shareholder making such
   purported Cash Election or Stock Election shall, for purposes hereof, be
   deemed to have made a Non-Election.

     (k) A Form of Election and a letter of transmittal shall be included with
   or mailed contemporaneously with each copy of the Proxy Statement mailed to
   shareholders of the Company in connection with the Company Meeting. Parent
   and the Company shall each use its reasonable best efforts to mail or
   otherwise make available the Form of Election and a letter of transmittal to
   all persons who become holders of shares of Company Common Stock during the
   period between the record date for the Company Meeting and the Election
   Deadline.

   1.8 Adjustment of Merger Consideration. In the event that pursuant to a
transaction announced after the date hereof and becoming effective prior to the
Effective Time (i) any distribution is made in respect of Parent Common Stock
other than a regular quarterly cash dividend or (ii) any stock dividend, stock
split, reclassification, recapitalization, combination or mandatory exchange of
shares occurs with respect to, or rights (other than non-mandatory offers to
exchange) are issued in respect of, Parent Common Stock, then, the Per Share
Stock Amount shall be adjusted accordingly. In the event of a dividend or
distribution to all holders of Parent Common Stock of any class of capital stock
of Parent or any Subsidiary of Parent ("Adjustment Shares"), the record date for
which is prior to the Effective Time (it is agreed that the appropriate
adjustment, in addition to the right to receive the Per Share Stock Amount prior
to such adjustment, shall be either, at Parent's option (provided that Parent
shall use reasonable efforts to be able to elect (A) before electing (B)), (A)
the right to receive, at the Effective Time, the number of Adjustment Shares
that such recipient would have received in respect of the Per Share Stock Amount
had such recipient owned the Per Share Stock Amount in Parent Common Stock as of
the date of this Agreement and held such through the Effective Time or and no
further adjustment shall be required under this Section 1.8 for such dividend or
distribution, or (B) the right to receive an amount of Parent Common Stock equal
in market value at the Effective Time to the market value at the Effective Time
of the number of Adjustment Shares that would have been received in respect of
the Per Share Stock Amount had the recipient thereof owned the Per Share Stock
Amount in Parent Common Stock as of the date of this Agreement and held such
through the Effective Time, and no further adjustment shall be required under
this Section 1.8 for such dividend distribution. For the purposes of the prior
sentence, "market value" means, with respect to any securities listed on a
national securities exchange or quoted on an 

                                      -6-

<PAGE>

interdealer quotation system, the average of the closing prices on the five
trading days prior to the Effective Time, or if not so listed, the fair market
value of such securities reasonably determined by the Board of Directors of
Parent on such date.

   1.9 No Further Ownership Rights in Company Common Stock. All shares of Parent
Common Stock issued upon the surrender for exchange of Certificates in
accordance with the terms hereof (including any cash paid pursuant to Sections
1.7, 1.10 or 2.4) shall be deemed to have been issued in full satisfaction of
all rights pertaining to such shares of Company Common Stock, and from and after
the Effective Time there shall be no further registration of transfers of the
shares of Company Common Stock which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates are presented to the
Surviving Corporation for any reason, they shall be canceled and exchanged as
provided in Article II.

   1.10 No Fractional Shares. No certificate or scrip representing fractional
shares of Parent Common Stock shall be issued upon the surrender for exchange of
Certificates, and such fractional share interests will not entitle the owner
thereof to vote or to any other rights of a stockholder of Parent.
Notwithstanding any other provision of this Agreement, each holder of shares of
Company Common Stock exchanged pursuant to the Merger who would otherwise have
been entitled to receive a fraction of a share of Parent Common Stock (after
taking into account all Certificates delivered by such holder) shall receive, in
lieu thereof, cash (without interest) in an amount equal to such fractional part
of a share of Parent Common Stock multiplied by the Per Share Cash Amount.

   1.11 Shares of Dissenting Shareholders. Notwithstanding anything in this
Agreement to the contrary, any shares of Company Common Stock that are
outstanding immediately prior to the Effective Time and that are held by
shareholders who shall not have voted in favor of the Merger and who shall have
given to the Company (and from whom the Company shall have actually received),
before the vote is taken at the Company Shareholders Meeting to adopt this
Agreement, written notice of such shareholder's intent to demand payment for
such shareholder's shares of Company Common Stock if the Merger is effectuated
in accordance with Article 13 of the NCBCA, and not failed to preserve such
shareholder's right to receive payment for such shares by failing to take those
actions required by such Article 13 within the time periods stipulated therein
(collectively, the "Dissenting Shares") shall not be converted into or represent
the right to receive the Merger Consideration. Such shareholders shall be
entitled to receive the amounts determined in accordance with the provisions of
such Article 13. If, after the Effective Time, any such holder fails to preserve
such rights, such Dissenting Shares shall thereupon be deemed to have been
converted into and to have become exchangeable for, as of the Effective Time,
the right to receive, without any interest thereon, the consideration provided
for in Section 1.7 as if such holder had made a Non-Election. The Company shall
give Parent prompt notice of any notice or demands for payment in accordance
with Article 13 of the NCBCA for shares of Company Common Stock received by the
Company, and Parent shall have the right to direct all proceedings, negotiations
and actions taken by the Company in respect thereof.

   1.12 Company Options. At the Effective Time, each unexpired and unexercised
outstanding option, whether or not then vested or exercisable in accordance with
its terms, to purchase shares of Company Common Stock (the "Company Options")
previously granted by the Company or its Subsidiaries under the Company's
Amended and Restated Stock Compensation Plan, the 1989 Stock Plan and the
Amended and Restated 1994 Long Term Incentive Plan (collectively, the "Company
Stock Option Plans") shall be canceled and converted into the right to receive
from the Parent, within 10 days following the Effective Time, cash in an amount
equal to the product of (a) the Per Share Cash Amount minus the exercise price
per share of such Company Option, times (b) the number of shares of Common Stock
which may be purchased upon exercise of such Company Option (whether or not then
exercisable). Prior to (but effective at) the Effective Time, the Company shall

                                      -7-
<PAGE>

use its reasonable best efforts to (i) obtain any consents from all holders of
Company Options and (ii) make any amendments to the terms of such stock option
or compensation plans or arrangements that, in the case of either clause (i) or
(ii), are necessary to give effect to the transactions contemplated by this
Section 1.12. Immediately prior to the Effective Time, the Company shall
terminate the Company Stock Option Plans effective as of the Effective Time.

                                   ARTICLE II.

                            EXCHANGE OF CERTIFICATES

   2.1 Closing. The closing of the Merger (the "Closing") shall take place at
8:00 a.m. on the first Business Day after satisfaction or waiver (as permitted
by this Agreement and applicable law) of the conditions (excluding conditions
that, by their terms, cannot be satisfied until the Closing Date) set forth in
Article VI (the "Closing Date") (provided that, if such conditions are satisfied
or waived upon completion of the Company Shareholders Meeting, the Closing shall
take place at least three, but not more than five, business days thereafter),
unless (a) Parent elects a later date (because, in its good faith judgment,
Parent believes that such delay is necessary in connection with avoiding
interference with a material transaction) that is not later than the Outside
Date or (b) another time or date is agreed to in writing by the parties hereto.
The Closing shall be held at the offices of Latham & Watkins, 885 Third Avenue,
Suite 1000, New York, NY 10022-4802, unless another place is agreed to in
writing by the parties hereto. The Articles of Merger and the Certificate of
Merger shall be filed at or as promptly as practicable following the time of the
Closing, and each shall contemplate the same Effective Time.

   2.2 Exchange Agent. As of the Effective Time, Parent shall deposit with such
bank or trust company as may be designated by Parent and be reasonably
acceptable to the Company (the "Exchange Agent") for the benefit of the holders
of shares of Company Common Stock and the holders of the Company Options, for
exchange or payment in accordance with this Section 2.2, through the Exchange
Agent, (i) certificates evidencing such number of shares of Parent Common Stock
equal to (x) the Per Share Stock Amount multiplied by (y) the aggregate number
of shares of Company Common Stock which may be converted into the right to
receive Parent Common Stock in the Merger, and (ii) (1) cash in an amount equal
to (x) the Per Share Cash Amount multiplied by (y) the aggregate number of
shares of Company Common Stock which may be converted into the right to receive
cash in the Merger, and (2) any cash necessary to pay amounts due pursuant to
Section 1.10 and Section 1.12 (such certificates for shares of Parent Common
Stock and such cash being hereinafter referred to as the "Exchange Fund"). The
Exchange Agent shall, pursuant to irrevocable instructions in accordance with
these Articles I and II, deliver the Parent Common Stock and cash contemplated
to be issued pursuant to Section 1.7 out of the Exchange Fund. The Exchange Fund
shall not be used for any other purpose. The Exchange Agent shall invest any
cash included in the Exchange Fund, as directed by Parent, on a daily basis. Any
interest and other income resulting from such investments shall be paid to
Parent.

   2.3 Exchange and Payment Procedures. (a) As soon as reasonably practicable
after the Effective Time, the Exchange Agent shall mail to each holder of record
of a Certificate or Certificates that were converted into the right to receive
shares of Parent Common Stock and/or cash pursuant to Section 1.7(b), (i) a
letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon proper delivery
of the Certificates to the Exchange Agent, and which shall be in such form and
have such other provisions as Parent may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for shares of Parent Common Stock and/or cash. Upon surrender of a Certificate
for cancellation to the Exchange Agent together with such letter of transmittal,
duly executed and completed in accordance with the instructions thereto, and
such other documents as 

                                      -8-


<PAGE>

may reasonably be required by the Exchange Agent, the holder of such Certificate
shall be entitled to receive in exchange therefor a certificate representing
that number of whole shares of Parent Common Stock and/or cash which such holder
has the right to receive pursuant to the provisions of Article I and this
Article II and the Certificate so surrendered shall forthwith be canceled. In
the event of a transfer of ownership of Company Common Stock that is not
registered in the transfer records of the Company, a certificate representing
the proper number of shares of Parent Common Stock and/or cash may be issued to
a Person other than the Person in whose name the Certificate so surrendered is
registered if the Certificate representing such Company Common Stock is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this Article
II, each Certificate shall be deemed at any time after the Effective Time to
represent only the right to receive upon surrender the certificate representing
shares of Parent Common Stock and/or cash as contemplated by this Article II.

   (b) As soon as reasonably practicable after the Effective Time, but no later
than five business days after the Effective Time, the Company, after approval by
Parent (which approval shall not be unreasonably withheld or delayed), shall
deliver to the Exchange Agent, a list of the holders of the Company Options,
their addresses and the amounts to be paid to each of them. Promptly after
receipt of such list, but no later than three days after receipts of such list,
the Exchange Agent shall pay the amounts shown on such schedule.

   2.4 Distributions with Respect to Unexchanged Shares. No dividends or other
distributions declared or made after the Effective Time with respect to Parent
Common Stock with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the shares of Parent
Common Stock to which such holder is entitled hereunder and no cash payment paid
to any such holder pursuant to Sections 1.7 and 1.10 until the holder of record
of such Certificate shall surrender such Certificate. Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
given to the record holder of the certificates representing whole shares of
Parent Common Stock to which such holder is entitled hereunder, without
interest, (i) at the time of such surrender, a certificate representing the
number of whole shares of Parent Common Stock and the amount of any cash to
which such holder is entitled pursuant to Sections 1.7 and 1.10 and the amount
of dividends or other distributions with respect to such whole shares of Parent
Common Stock with a record date after the Effective Time and a payment date
prior to their date of issuance to such holder, and (ii) at the appropriate
payment date, the amount of dividends or other distributions with a record date
after the Effective Time but prior to surrender and a payment date subsequent to
surrender payable with respect to such whole shares of Parent Common Stock.

   2.5 Termination of Exchange Fund. Any portion of the Exchange Fund which
remains undistributed to the holders of Certificates for six months after the
Effective Time shall be delivered to Parent, upon demand, and any shareholders
or optionholders of the Company who have not previously complied with the
provisions of this Article II shall thereafter look only to Parent for payment
of their claim for Parent Common Stock and/or cash and any dividends or
distributions with respect to Parent Common Stock. Any portion of the Exchange
Fund remaining unclaimed by holders of Company Common Stock five years after the
Effective Time (or such earlier date immediately prior to such time as such
portion would otherwise escheat to or become property of any Governmental
Entity) shall, to the extent permitted by applicable law, become the property of
the Surviving Corporation free and clear of any claims or interest of any Person
previously entitled therein.

   2.6 No Liability. To the fullest extent permitted by law, none of Parent,
Merger Sub, the Company or the Surviving Corporation shall be liable to any
holder of Company Common Stock or 

                                      -9-


<PAGE>

Parent Common Stock, as the case may be, for any shares (or dividends or
distributions with respect thereto) and/or cash delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

   2.7 Lost Certificates. If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the Person claiming
such Certificate to be lost, stolen or destroyed and, if required by Parent, the
posting by such Person of a bond in such reasonable amount as Parent may direct
as indemnity against any claim that may be made against it with respect to such
Certificate, the Exchange Agent will deliver in exchange for such lost, stolen
or destroyed Certificate the shares of Parent Common Stock and/or any cash.

   2.8 Withholding Rights. Parent and the Exchange Agent shall be entitled to
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of shares of Company Common Stock or holders of Company
Options such amounts as Parent or the Exchange Agent, as applicable, is required
to deduct and withhold with respect to the making of such payment under the
Code, or any provision of state, local or foreign Tax law. To the extent that
amounts are so withheld by Parent or the Exchange Agent, such withheld amounts
shall be treated for all purposes of this Agreement as having been paid to the
holder of the shares of Company Common Stock in respect of which such deduction
and withholding was made by such party.

   2.9 Further Assurances. At and after the Effective Time, the officers and
directors of the Surviving Corporation will be authorized to execute and
deliver, in the name and on behalf of the Company or Merger Sub, any deeds,
bills of sale, assignments or assurances and to take and do, in the name and on
behalf of the Company of Merger Sub, any other actions and things to vest,
perfect or confirm of record or otherwise in the Surviving Corporation any and
all right, title and interest in, to and under any of the rights, properties or
assets acquired or to be acquired by the Surviving Corporation as a result of,
or in connection with, the Merger.

   2.10 Stock Transfer Books. At 5:00 p.m., New York City time, on the day the
Effective Time occurs, the stock transfer books of the Company shall be closed
and there shall be no further registration of transfers of shares of Company
Common Stock thereafter on the records of the Company. From and after the
Effective Time, the holders of Certificates shall cease to have any rights with
respect to such shares of Company Common Stock formerly represented thereby,
except as otherwise provided herein or by law. On or after the Effective Time,
any Certificates presented to the Exchange Agent or Parent for any reason shall
be converted into the Merger Consideration with respect to the shares of Company
Common Stock formerly represented thereby.

                                  ARTICLE III.

                         REPRESENTATIONS AND WARRANTIES

   3.1 Representations and Warranties of the Company. The Company represents and
warrants to Parent and Merger Sub as follows:

     (a) Organization, Standing and Power. The Company is a corporation duly
   organized and validly existing and in good standing under the laws of its
   jurisdiction of incorporation. Each of the Company's Subsidiaries has been
   duly formed and is validly existing under the laws of the jurisdiction of its
   formation except where the failure of a Subsidiary to be duly formed and
   validly existing in such jurisdictions could not reasonably be expected,
   either individually or in the aggregate, to have a Material Adverse Effect on
   the Company. Each of the Company and its Subsidiaries is duly qualified and
   in good standing to do business in each jurisdiction in which the nature of
   its business or the ownership or leasing of its properties makes such
   qualification necessary, other than, with respect to the Subsidiaries, in
   such jurisdictions where the failure so to qualify could not reasonably be
   expected, either individually or in the aggregate, to have a 

                                      -10-
<PAGE>

   Material Adverse Effect on the Company. Each of the Company and its
   Subsidiaries has the requisite corporate power and authority to own, lease
   and operate its properties and conduct its business as currently or proposed
   to be conducted, except, with respect to the Subsidiaries, where the lack of
   such requisite power could not reasonably be expected, either individually or
   in the aggregate, to have a Material Adverse Effect on the Company. The
   Company has previously furnished to Parent true, complete and correct copies
   of the Organizational Documents of the Company and its Subsidiaries as in
   effect on the date of this Agreement, and neither the Company nor its
   Subsidiary is in default thereunder or acting in conflict therewith.

   (b)Capital Structure.

     (i) The authorized capital stock of the Company consists of (A) 250,000,000
   shares of Company Common Stock, of which 36,780,009, shares are issued and
   outstanding as of the date hereof and of which 36,780,009 shares plus such
   number of shares as may be issued consistent with Section 4.1(b) shall be
   issued and outstanding as of the Effective Time, and no shares are held by
   the Company or its Subsidiaries as treasury stock, (B) 30,000,000 shares of
   Class B Common Stock, par value $.01 per share, of which no shares are issued
   or outstanding, and (C) 1,000,000 shares of preferred stock, par value $.01
   per share, of which no shares are issued or outstanding. All issued and

     (i) The Company has filed all required reports, schedules, forms,
   statements and other documents required to be filed by it with the Securities
   and Exchange Commission (the "SEC") since January 1, 1996 (collectively,

   therein, the "Company SEC Reports"). No Subsidiary of the Company is required
   to file any form, report or other document with the SEC. None of the Company

   contained or will contain any untrue statement of a material fact or omitted
   or will omit to state a material fact required to be stated therein or
   necessary to make the statements therein, in light of the circumstances under

   (including the related notes) included in the Company SEC Reports presents
   fairly, in all material respects, the consolidated financial position and
   consolidated results of operations and cash flows of the Company and its
   Subsidiaries as of the respective dates or for the respective periods set
   forth therein, all in conformity with generally accepted accounting
   principles ("GAAP") consistently applied during the periods involved except
   as otherwise noted therein, and subject, in the case of the unaudited interim
   financial statements, to normal and recurring year-end adjustments that have
   not been and are not expected to be material in amount. All of such the
   Company SEC Reports, as of their respective dates (and as of the date of any
   amendment to the respective the Company SEC Report), complied as to form in
   all material respects with the applicable requirements of the Securities Act
   and the Exchange Act and the rules and regulations promulgated thereunder.

     (ii) Except for, and to the extent of, those liabilities that are reflected
   or reserved against, to the extent reflected or reserved against, on the

   December 31, 1997, and except for liabilities and obligations incurred in the
   ordinary course of business consistent with past practice since June 30,
   1998, and except and as to the extent disclosed in Schedule 3.1(d)(ii),
   neither the Company nor any of its Subsidiaries has any liabilities or
   obligations of any nature whatsoever (whether fixed, absolute, accrued,
   contingent or otherwise and whether due or to become due) that individually
   or in the aggregate could reasonably be expected to have a Material Adverse
   Effect on the Company.

     (e) Proxy Statement/Registration Statement. The information to be supplied
   by the Company for inclusion in the Registration Statement shall not at the
   time the Registration Statement is filed with or declared effective by the
   SEC or at the date of the Company Shareholders Meeting contain any untrue
   statement of a material fact or omit to state any material fact required to
   be stated in the Registration Statement or necessary in order to make the
   statements in the Registration Statement, in light of the circumstances under
   which they were made, not misleading. The Proxy Statement shall not, on the
   date the Proxy Statement is first mailed to shareholders of the Company, at
   the time of the Company Shareholders' Meeting and at the Effective Time,
   contain any statement which, at such time and in light of the circumstances
   under which it shall be made, is false or misleading with respect to any
   material fact, or omit to state any material fact necessary in order to make
   the statements made in the Proxy Statement not false or misleading (excluding
   any statement based upon information supplied by Parent for inclusion in the
   Proxy Statement).

   registrations, variances, exemptions, orders and approvals of all
   Governmental Entities which are necessary or advisable to the operation of
   their businesses, other than those which, individually or in the aggregate,
   the failure to hold could not reasonably be expected to have a Material
   Adverse Effect on the Company (the "Company Permits"). All such Company
   Permits are valid and in full force and effect, and no suspension or
   cancellation of any such Company Permit is pending or, to the knowledge of

   violation, (3) would not result in cognizable damage to the business

   a materially disproportionate effect on the Company, there is no litigation,
   arbitration, claim, suit, action, investigation or proceeding pending,
   affecting or, to the knowledge of the Company, threatened, against the
   Company or any of its Subsidiaries or their assets, which individually, or

   the date hereof could be reasonably expected to result in a material
   liability, and there is no litigation, claim, suit, action, investigation or
   proceeding pending, affecting or, to the knowledge of the Company or any of

   has not been paid; (ii) the Company and each of its Subsidiaries have paid
   all material Tax liabilities that are shown as due on such filed Tax Returns
   or that the Company or any of its Subsidiaries is obligated to withhold from

   to matters contested in good faith; (iii) as of the date hereof, except as

   effect that, as of such date, the Merger Consideration is fair, from a
   financial point of view, to the holders of Company Common Stock.

     (o) Year 2000 Compliance. The Company has taken steps (summarized in

   described therein), has resolved (or is in the process of resolving) any
   issues arising as a result of tests taken or otherwise to the knowledge of
   the Company, and is not aware of any fact that would lead one to reasonably
   conclude that the Company will be unable to resolve any of such issues on the

   Company and its Subsidiaries have complied with all applicable Environmental
   Laws; (ii) the properties currently owned or operated by the Company and its
   Subsidiaries (including soils, groundwater, surface water, buildings or other

   reasonably likely to give rise to liability or remediation obligations for
   the Company or any Subsidiary under any applicable Environmental Law; (iii)
   the properties formerly owned or operated by the Company or any of its
   Subsidiaries were not contaminated with any Hazardous Substance during the
   period of ownership or operation by the Company or any of its Subsidiaries to
   an extent reasonably likely to give rise to liability or remediation
   obligations for the Company or any Subsidiary; (iv) neither the Company nor
   any of its Subsidiaries is reasonably likely to be subject to liability or

   Subsidiary under any Environmental Laws; (v) neither the Company nor any of
   its Subsidiaries has received any notice, demand, letter, claim or request
   for information indicating that the Company or any of its Subsidiaries may be
   in violation of or subject to liability under any Environmental Law; (vi)
   neither the Company nor any of its Subsidiaries is subject to any orders,
   decrees, injunctions or other arrangements with any Governmental Entity or
   any indemnity or other agreement with any third party relating to any

   circumstances or conditions involving the Company or any of its Subsidiaries
   that could reasonably be expected to result in any claims, liability,

   herein, the term "Environmental Law" means any federal, state, local or
   foreign law, statute, ordinance, regulation, judgment, order, decree,
   arbitration award, agency requirement, license, permit, authorization or
   common law, relating to the protection, investigation or restoration of the
   environment, health and safety, or natural resources. As used herein, the
   term "Hazardous Substance" means any substance that is: (A) a pollutant or

   materials or radon; or (B) any other substance that may be the subject of
   regulatory action by any Governmental Entity pursuant to any Environmental
   Law.

     (r) Intellectual Property. The Company and its Subsidiaries own, or have
   the defensible right to use, the Intellectual Property used in their
   respective businesses, except where the failure to own or have the right to
   use such Intellectual Property, individually or in the aggregate, does not
   and would not have a Material Adverse Effect on the Company. As used herein,
   "Intellectual Property" means all industrial and intellectual property
   rights, including Proprietary Technology, patents, patent applications,
   trademarks, trademark applications and registrations, service marks, service
   mark applications and registrations, copyrights, know-how, licenses, trade
   secrets, proprietary processes, formulae and customer lists; and "Proprietary

<PAGE>

   Subsidiaries or Parent and its Subsidiaries, as the case may be, in the
   conduct of their business or used, employed or exploited in the development,
   license, sale, marketing, distribution or maintenance thereof, and all
   documentation and media constituting, describing or relating to the above,
   including manuals, memoranda, know-how, notebooks, software, records and
   disclosures.

     (s) Properties. Schedule 3.1(s) lists all material real property and
   material interests in real property owned by the Company or its Subsidiaries
   or leased by the Company or its Subsidiaries as lessee or lessor, as well as
   all material real property and material interests in real property used or
   held for use as cell sites.

     (t) Assets. All assets of the Company are in good operating condition and
   sufficient for the Company's use thereof, normal wear and tear excepted,
   except where such failure to be in good operating condition could not
   reasonably be expected to result in a Material Adverse Effect. The Company
   owns or has rights to use all assets necessary for the conduct of its
   business and operations or reflected on the balance sheet included in the
   most recent Form 10-Q filed by the Company with the SEC, except where the
   lack of such ownership or rights could not reasonably be expected,
   individually or in the aggregate, to have a Material Adverse Effect on the
   Company.

     (u) Insurance. The Company and its Subsidiaries are insured, and shall
   continue to maintain insurance, in such amounts and against such losses and
   risks as are consistent with industry practice and, in the reasonable
   judgment of senior management of the Company, are adequate to protect the
   properties and business of the Company and its Subsidiaries. As of the date
   hereof, no written notice of cancellation or nonrenewal with respect to any
   material insurance policy has been received by the Company or any of its
   Subsidiaries. Copies of all such insurance policies have been furnished or
   made available to Parent.

   limitation, all federal and state securities laws. None of the offer to
   purchase or any of the related materials to be sent or delivered by the
   Company in connection with the Tender Offer shall contain any untrue
   statement of a material fact or omit to state a material fact required to be
   stated therein or necessary in order to make the statements therein, in light
   of the circumstances under which they were made, not misleading. The
   supplemental indenture (the "Supplemental Indenture") to be entered into in
   connection with the Tender Offer, upon execution by the Company and the
   Trustee, shall be valid and enforceable and in full force and effect, and
   neither the Company nor any of its Subsidiaries shall violate any provision
   of, or commit or fail to perform any act which, with or without notice, lapse
   of time, or both, could reasonably be expected to constitute a default under
   the provisions of, any such Supplemental Indenture.

   3.2 Joint and Several Representations and Warranties of Parent and Merger
Sub. Parent and Merger Sub jointly and severally represent and warrant to the
Company as follows:

     (a) Organization, Standing and Power. Each of Parent and Merger Sub is a
   corporation duly organized and is validly existing and in good standing under
   the laws of the jurisdiction of its incorporation, and has the requisite
   corporate power and corporate authority to own, lease, and operate its
   properties and assets and to carry on its business as it is now being
   conducted. Each of Parent and Merger Sub is duly qualified and in good
   standing to do business in each jurisdiction in which the nature of its
   business or the ownership or leasing of its properties makes such
   qualification necessary, other than in such jurisdictions where the failure
   so to qualify or be 

                                      -21-
<PAGE>

   in good standing could not reasonably be expected, individually or in the
   aggregate, to have a Material Adverse Effect on Parent.

     (b) Authorization and Execution. Each of Parent and Merger Sub has the
   requisite corporate power and authority to execute and deliver this Agreement
   and to consummate the transactions contemplated hereby. The execution,
   delivery, and performance by each of Parent and Merger Sub of this Agreement
   have been duly authorized by the Board of Directors of such corporation and
   by Parent as sole stockholder of Merger Sub, and no further corporate action
   of Parent or Merger Sub is necessary to consummate the transactions
   contemplated hereby. Each of Parent and Merger Sub have duly executed and
   delivered this Agreement, and this agreement constitutes the legal, valid,
   and binding obligation of such party enforceable against it in accordance
   with its terms, except as such enforceability may be limited by bankruptcy,
   insolvency, reorganization, moratorium and similar laws relating to or
   affecting creditors generally, by general equity principles (regardless of
   whether such enforceability is considered in a proceeding in equity or at
   law) or by an implied covenant of good faith and fair dealing.

     (c) Parent Common Stock. The shares of Parent Common Stock to be issued
   pursuant to Article I will, when issued, be duly authorized, validly issued,
   fully paid and nonassessable, and no stockholder of Parent is entitled to
   preemptive rights as a result of the issuance of the Parent Company Stock
   hereunder. The Parent Common Stock to be issued in the Merger will, when
   issued, be registered under the Securities Act and the Exchange Act and
   registered or exempt from registration under any applicable state securities
   laws, in each case for delivery hereunder to holders of Company Common Stock.
   The Parent has available for issuance under its Organization Documents a
   sufficient number of shares of authorized Parent Common Stock necessary to
   satisfy Parent's obligations under this Agreement.

     (d) No Conflicts. The execution and delivery of this Agreement does not or
   will not, as the case may be, (i) conflict with or result in a breach of the
   Articles or Certificate of Incorporation, Bylaws or similar organizational
   documents, as currently in effect, of Parent or any of its "Significant
   Subsidiaries" (as such term is defined in regulations promulgated under the
   Securities Act or the Exchange Act), (ii) except for (A) the consents,
   approvals, orders, authorizations, registrations, declarations and filing
   required under or in relation to clause (x) of Section 3.1(c)(iii) and (B)
   such consents, approvals, orders, authorizations, registrations, declarations
   and filings the failure of which to make or obtain could not reasonably be
   expected to have a Material Adverse Effect on Parent or impair or delay the
   ability of Parent or consummate the transactions contemplated hereby, require
   any filing with, or consent or approval of, any Government Entity having
   jurisdiction over any of the business or assets of Parent or any of its
   Significant Subsidiaries, (iii) violate any statute, law, ordinance, rule or
   regulation applicable to Parent or any of its Significant Subsidiaries or any
   injunction, judgment, order, writ, or decree to which Parent or any of its
   Significant Subsidiaries is subject, or (iv) result in a breach of, or
   constitute a default or an event which, with the passage of time or the
   giving of notice, or both, would constitute a default, give rise to a right
   of termination, cancellation, or acceleration, create any entitlement of any
   third party to any material payment or benefit, require the consent of any
   third party, or result in the creation of any lien on the assets or stock of
   Parent or any of its Significant Subsidiaries, except, in the case of clauses
   (ii), (iii) and (iv), where the violation, breach, default, termination,
   cancellation, acceleration, payment, benefit, or lien, or the failure to make
   such filing or obtain such consent or approval could not, individually or in
   the aggregate, reasonably be expected to have a Material Adverse Effect on
   Parent.

   (e) Reports and Financial Statements.

          (i) Parent has filed all required reports, schedules, forms, 
          statements and other documents required to be filed by it with the SEC
          since January 1, 1996 (collectively, 

                                      -22-

<PAGE>

          including all exhibits thereto and documents incorporated by reference
          therein, the "Parent SEC Reports"). None of the Parent SEC Reports, as
          of their respective dates (and, if amended or superseded by a filing 
          prior to the date of this Agreement, then on the date of such filing),
          contained or will contain any untrue statement of a material fact or
          omitted or will omit to state a material fact required to be stated
          therein or necessary to make the statements therein, in light of the
          circumstances under which they were made, not misleading. Each of the
          financial statements (including the related notes) included in the 
          Parent SEC Reports presents fairly, in all material respects, the 
          consolidated financial position and consolidated results of operations
          and cash flows of Parent and its Subsidiaries as of the respective 
          dates or for the respective periods set forth therein, all in 
          conformity with GAAP consistently applied during the periods involved 
          except as otherwise noted therein, and subject, in the case of the 
          unaudited interim financial statements, to normal and recurring 
          year-end adjustments that have not been and are not expected to be 
          material in amount. All of such Parent SEC Reports, as of their
          respective dates (and as of the date of any amendment to the 
          respective Parent SEC Report), complied as to form in all material
          respects with the applicable requirements of the Securities Act and 
          the Exchange Act and the rules and regulations promulgated thereunder.

     (f) Proxy Statement/Registration Statement. The Registration Statement
   shall not at the time the Registration Statement is declared effective by the
   SEC contain any untrue statement of a material fact or omit to state any
   material fact required to be stated in the Registration Statement or
   necessary in order to make the statements in the Registration Statement, in
   light of the circumstances under which they were made, not misleading
   (excluding any statement based upon information supplied by the Company for
   inclusion in the Proxy Statement). The information to be supplied by Parent
   for inclusion in the Registration Statement shall not on the date the Proxy
   Statement is first mailed to shareholders of the Company, at the time of the
   Company Shareholders' Meeting, and at the Effective Time, contain any
   statement that, at such time and in light of the circumstances under which it
   shall be made, is false or misleading with respect to any material fact, or
   omit to state any material fact necessary in order to make the statements
   made in the Proxy Statement not false or misleading.

     (g) Absence of Certain Changes or Events. Except as expressly disclosed in
   the Parent SEC Reports filed prior to the date of this Agreement, since June
   30, 1998, there has not been a Material Adverse Effect on Parent or any
   development or combination of developments of which management of Parent has
   knowledge which is reasonably likely to result in such an effect.

     (h) No Vote Required. No vote or approval of the holders of any class of
   Parent shares is necessary to approve this Agreement and the transactions
   contemplated hereby.

     (i) Brokers or Finders. No agent, broker, investment banker, financial
   advisor or other firm or Person engaged by Parent or Merger Sub is or will be
   entitled to any broker's or finder's fee or any other similar commission or
   fee from the Company or its Subsidiary in connection with any of the
   transactions contemplated by this Agreement.

     (j) Ownership of Company Common Stock. Except for Company Common Shares
   which Parent may acquire pursuant to the terms of the Option Agreement and
   the Voting Agreements, Parent "beneficially owns" (as such terms are used in
   connection with Rule 13d-3 under the Exchange Act) less than 1% of the
   outstanding Company Common Shares.

     (k) Merger Sub. Merger Sub was formed solely for the purpose of effecting
   the Merger and has not engaged in any business activities or conducted any
   operations other than in connection with the Merger. Except for obligations
   or liabilities incurred in connection with its incorporation or organization
   and the transactions contemplated by this Agreement, and except 

                                      -23-

<PAGE>

   for this Agreement and any other agreements or arrangements contemplated by
   this Agreement, Merger Sub has not incurred, directly or indirectly, through
   any subsidiary or affiliate, any obligations or liabilities or entered into
   any agreement or arrangements with any person.

   of the Company in connection with the Company Shareholders' Meeting to
   consider the Merger and the issuance of Parent Common Stock in connection
   therewith, and Parent shall prepare and file with the SEC a registration
   statement on Form S-4 pursuant to which the shares of Parent Common Stock to
   be issued in the Merger will be registered under the Securities Act (the

   after the Proxy Statement has been declared effective. Parent and the Company
   shall use reasonable best efforts to cause the Registration Statement to
   become effective as soon after the filing as practicable. The Proxy Statement

   Company in favor of this Agreement and the Merger unless the Board is not
   required to make such recommendation pursuant to clause (e) below. Parent and
   the Company shall make all other necessary filings with respect to the Merger
   under the Securities Act and the Exchange Act and the rules and regulations
   thereunder. If at any time before the Effective Time any event relating to
   the Company or Parent, or any of its affiliates, officers, or directors, is
   discovered by the Company or Parent, respectively, that should be set forth
   in an amendment to the Registration Statement or a supplement to the Proxy
   Statement, such party shall promptly so inform the other.

     (b) The Company shall take all action necessary to cause the representation
   set forth in Section 3.1(e) to be true and correct at all applicable times
   with respect to each of the Proxy Statement and the Registration Statement.

   securities laws in connection with the transactions contemplated by this
   Agreement.

     (e) The Company shall, as soon as practicable following the date of this
   Agreement, duly call, give notice of, convene and hold a meeting of its
   shareholders (the "Company Shareholders Meeting") for the purpose of
   obtaining the Required Company Votes with respect to this Agreement. The
   Board of Directors of the Company shall unanimously recommend adoption of
   this Agreement by the shareholders of the Company and, upon Parent's request,
   reconfirm such recommendation (provided that the Board of Directors of the
   Company need not (1) make or reconfirm such recommendation (x) if at the time
   that it would otherwise be required to make or reconfirm such recommendation
   the Company is not then in breach of its obligations under Section 5.4 and
   (y) in such event, if and only to the extent that the Board of Directors of
   the Company concludes in good faith (after having consulted with and
   considered the advice of outside legal counsel) in connection with the
   receipt of a Superior Proposal that such action is necessary in order for its
   directors to comply with their respective fiduciary duties under applicable
   law, or reconfirm such recommendation (2) reconfirm such recommendation if no
   other Acquisition Proposal is pending or in Parent's reasonable judgment
   likely to become pending. Subject to the foregoing, the Company shall use
   reasonable best efforts to solicit such adoption.

   5.2 Access to Information. Upon reasonable notice, the Company and its
Subsidiaries shall afford to the officers, employees, accountants, counsel,
financial advisors and other representatives of Parent reasonable access during
normal business hours, during the period prior to the Effective Time, to all its
personnel, properties, books, contracts, commitments and records and, during
such period, the Company and its Subsidiaries shall furnish promptly to Parent
(a) a copy of each report, schedule, registration statement and other document
filed, published, announced or received by it during such period pursuant to the
requirements of Federal or state securities laws, as applicable (other than
reports or documents which such party is not permitted to disclose under
applicable law) and (b) consistent with its legal obligations, all other
information concerning its business, properties and personnel as Parent may
reasonably request; provided, however, the Company may restrict the foregoing
access to the extent that (i) a Governmental Entity requires the Company or any
of its Subsidiaries to restrict access to any properties or information
reasonably related to any such contract on the basis of applicable laws and
regulations with respect to national security matters or (ii) any law, treaty,
rule or regulation of any Governmental Entity applicable to the Company or its
Subsidiaries requires the Company or its Subsidiaries to restrict access to any
properties or information.

   5.3 Approvals and Consents; Cooperation. Subject to Section 4.2, each of the
Company and Parent shall cooperate with each other and use (and shall cause
their respective Subsidiaries to use) its reasonable best efforts to take or
cause to be taken all actions, and do or cause to be done all things, necessary,
proper or advisable on their part under this Agreement and applicable laws to
consummate and make effective the Merger and the other transactions contemplated
by this Agreement as soon as practicable, including (i) preparing and filing
promptly, after consulting with the other party and providing an opportunity to
review related documentation in advance, all documentation to effect all
necessary applications, notices, petitions, filings, tax ruling requests and
other documents and to obtain all consents, waivers, licenses, registrations,
permits, authorizations, tax rulings and authorizations necessary or advisable
to be obtained from any third party and/or any Governmental Entity in order to
consummate the Merger or any of the other transactions contemplated by this
Agreement and (ii) taking all reasonable steps as may be necessary to obtain all
such consents, waivers, licenses, registrations, permits, authorizations, tax
rulings, orders and approvals. Without limiting the generality of the foregoing,
the Company and Parent agree to make all necessary filings in connection with
the Required Regulatory Approvals promptly following the date of this Agreement,
and to use its reasonable best efforts to furnish or cause to be furnished, as
promptly as practicable, all information and documents requested with respect to
such Required 

                                      -29-
<PAGE>

Regulatory Approvals and shall otherwise cooperate with the applicable
Governmental Entity in order to obtain any Required Regulatory Approvals.
Subject to Section 4.2, each of the Company and Parent shall use its reasonable
best efforts to resolve such objections, if any, as any Governmental Entity may
assert with respect to this Agreement and the transactions contemplated hereby
in connection with the Required Regulatory Approvals in as expeditious a manner
as possible. Subject to Section 4.2, in the event that a suit is instituted by
a Person or Governmental Entity challenging this Agreement and the transactions
contemplated hereby as violative of applicable antitrust or competition laws or
the Communications Act, each of the Company and Parent shall use its reasonable
best efforts to resist or resolve such suit. The Company and Parent each shall,
upon request by the other, furnish the other with all information concerning
itself, its Subsidiaries, directors, officers and shareholders and such other
matters as may be reasonably be necessary or advisable in connection with the
Proxy Statement or any other statement, filing, tax ruling request, notice or
application made by or on behalf of the Company, Parent or any of their
respective Subsidiaries to any third party and/or any Governmental Entity in
connection with the Merger or the other transactions contemplated by this
Agreement.

   5.4 Acquisition Proposals. The Company agrees that it and its Subsidiaries,
officers, directors, employees, agents and representatives (including any
investment banker, attorney or accountant retained by it) shall not, directly or
indirectly, initiate, solicit, encourage or otherwise facilitate any inquiries
or the making of any proposal or offer with respect to a merger, reorganization,
share exchange, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving, or any purchase of
any substantial portion of the assets of, or any equity securities of, or any
transaction that would involve the transfer or potential transfer of control of,
the Company (any such proposal or offer being hereinafter referred to as an
"Acquisition Proposal") and has terminated any discussions or negotiations with,
and the provision of information or data to, any Person (other than Parent)
respecting an Acquisition Proposal. The Company further agrees that it and its
Subsidiaries, officers, directors, employees, agents and representatives
(including any investment banker, attorney or accountant retained by it) shall
not, directly or indirectly, provide any confidential information or data to any
Person relating to or in contemplation of an Acquisition Proposal or engage in
any negotiations or discussions relating to or in contemplation of an
Acquisition Proposal; provided, however, that nothing contained in this
Agreement shall prevent the Company or its Board of Directors from (a) complying
with Rule 14e-2 promulgated under the Exchange Act with regard to any
Acquisition Proposal; and (b) if any only to the extent that the Board of
Directors of the Company concludes in good faith (after having consulted with
and considered the advice of outside legal counsel) that such Acquisition
Proposal would, if consummated, result in a transaction more favorable to the
Company shareholders from a financial point of view than the transaction
contemplated by this Agreement (any such more favorable Acquisition Proposal
being referred to in this Agreement as a "Superior Proposal"), until the
Required Company Vote has been obtained, the Company may furnish or cause to be
furnished confidential information or data and may participate in such
negotiations and discussions but only if (i) the Company is not then in breach
of its obligations under this Section, (ii) (and only to the extent that) the
Board of Directors of the Company concludes in good faith (after having
consulted with and considered the advice of outside legal counsel) that such
action is necessary in order for its directors to comply with their respective
fiduciary duties under applicable law and (iii) confidentiality arrangements on
terms no less beneficial to the Company as those entered into by Parent are
entered into with respect thereto. The Company will notify Parent immediately if
any inquiries, proposals or offers respecting an Acquisition Proposal are
received by, any such information or data is requested from, or any such
discussions or negotiations are sought to be initiated or continued with, it or
any such Persons indicating, in connection with such notice, the name of such
Person and the material terms and conditions of any proposals or offers, and
shall keep Parent apprised with respect to the status and terms thereof. The
Company also will promptly request each Person that has heretofore executed a
confidentiality 

                                      -30-


<PAGE>

agreement in connection with its consideration of an Acquisition Proposal to
return all confidential information heretofore furnished to such Person by or
on behalf of it or any of its Subsidiaries and will not waive any "standstill"
provision of any such, or any other, agreement. The Company shall provide
Parent at least two business days advance notice of its intention to present to
its Board of Directors or accept any Superior Proposal and shall provide Parent
with a summary of the terms and conditions thereof. Notwithstanding the
foregoing, none of the actions set forth on Schedule 5.4 shall constitute an
Acquisition Proposal.

   Parent shall or shall cause the Surviving Corporation to maintain in effect
   employee benefit plans and arrangements which provide benefits which have a
   value substantially comparable, in the aggregate, to the benefits provided by
   the Company Benefit Plans (not taking into account the value of any benefits
   under any such plans which are equity based); provided, that Parent at its
   sole option may provide employee benefits to the Surviving Corporation which,
   in the aggregate, are substantially comparable to those applicable to
   similarly situated employees of Parent or its Subsidiaries. At the request of
   Parent, the Company shall, prior to the Effective Time, terminate the
   Company's 401(k) Plan effective immediately prior to the Effective Time. The
   Company shall terminate the Company's Employee Stock Purchase Plan (the
   "ESPP") for each fiscal quarter beginning on or after October 1, 1998 and
   shall cease all offering periods that begin on or after September 30, 1998.

     (b) For purposes of determining eligibility to participate, vesting and
   accrual or entitlement to benefits where length of service is relevant under
   any employee benefit plan or arrangement of Parent, the Surviving Corporation
   or any of their respective Subsidiaries, employees of the Company and its
   Subsidiaries as of the Effective Time shall receive service credit for
   service with the Company and any of its Subsidiaries to the same extent such
   service credit was granted under the Company Benefit Plans, subject to
   offsets for previously accrued benefits and no duplication of benefits
   (except that no such credit shall be applied for (i) benefit accrual or
   entitlement purposes under defined benefit pension plans or the schedule of
   benefits under Parent's severance pay and short term disability plans and
   policies, (ii) eligibility to receive post- retirement ancillary benefits
   (consisting at this time of medical, dental, death and telephone concession
   benefits) or (iii) calculating Parent service for purposes of "bridging"
   prior Parent service under Parent benefit plans).

     (c) Parent shall cause the Surviving Corporation to assume and honor in
   accordance with their terms (i) all written employment, severance and
   termination plans and agreements (including change in control provisions) of
   employees of the Company and its Subsidiaries provided to Parent on or prior
   to the date of this Agreement and (ii) the Tax Reimbursement Agreements
   identified in Schedule 5.5(c)(ii).

counsel, accountants, investment bankers, experts and consultants to a party
hereto and its affiliates) incurred by a party or on its behalf in connection
with or related to the authorization, preparation, negotiation, execution and
performance of this Agreement and the transactions contemplated hereby,

Corporation shall cause to be maintained in effect (i) for a period of six years
after the Effective Time, the current provisions regarding indemnification of
officers and directors contained in the Organizational Documents of the Company
and its Subsidiaries and (ii) for a period of six years, the current policies of
directors' and officers' liability insurance and fiduciary liability insurance
maintained by the Company (provided that the Surviving Corporation may
substitute therefor policies of at least the same coverage and amounts
containing terms and conditions which are, in the aggregate, no less
advantageous to the insured) with respect to claims arising from facts or events
that occurred on or before the Effective Time, provided that the annual premium
therefor is not in excess of 200% of the last annual premium paid by the Company

best efforts to accommodate the comments of, Parent before issuing any press
release or otherwise making any public statement with respect to this Agreement
or the transactions contemplated hereby.

"Tender Offer") to purchase the Company's outstanding 9 3/8% Debentures due 2006
(the "Debentures") on the terms and conditions set forth in Schedule 5.9 hereto,
which shall effect the deletion of substantially all of the covenants in the
related Indenture, dated as of April 1, 1996, as amended by the First
Supplemental indenture thereto, dated as of April 1, 1996 (as so amended, the
"Indenture"), which may be deleted therefrom with the consent (the "Requisite

forth in Schedule 5.9 (the "Majority Covenants").

   (b) The Tender Offer shall be commenced as promptly as practicable following
November 4, 1998, and, in any event, within three days following such date (the
"Third Day"). Except as may be required by law, the Company shall not extend the
consent date or expiration date of, or amend or waive any terms or conditions
of, the Tender Offer, or deem any condition thereof not to be satisfied, without
Parent's prior written consent (in its sole discretion), provided that, on any
scheduled consent date under the Tender Offer prior to November 25, 1998, the
Company may extend such consent date, for one business day, if on such consent
date the Requisite Consent has not been received.

   (c) All documentation delivered in connection with the Tender Offer shall be

reliance letters permitting Parent and the Company to rely on any legal opinions
or certificates delivered in connection therewith.

<PAGE>

   (d) If the Tender Offer is commenced (x) upon the receipt of the Requisite
Consent, the Company shall execute and use its best efforts to cause the Trustee
to execute the Supplemental Indenture at the Consent Time (as defined in the
Tender Offer) and (y) upon the expiration of the period for tendering Debentures
under the Tender Offer, if the conditions to consummation of the Tender Offer
have been satisfied, the Company shall accept for payment and purchase all
Debentures validly tendered thereunder and shall deliver such Debentures to the
Trustee under the Indenture for cancellation.

   (e) Promptly following the expiration of the period for tendering Debentures
under the Tender Offer without Debentures being purchased thereunder, or upon
the Third Day if the Tender Offer shall not have been commenced by such day, the
Company shall make the deposit (the "Deposit") contemplated by Section 6.1A(1)
of the Indenture and shall use its best efforts to satisfy all other conditions
to the covenant defeasance provisions of Sections 6.1 and 6.1A of the Indenture
so that such covenant defeasance shall become effective with respect to all
Debentures as promptly as practicable thereafter.

   5.10 Affiliate Letters. Prior to the mailing of the Joint Proxy
Statement/Prospectus, the Company shall deliver to Parent a list of names and
addresses of those Persons, that to the knowledge of the Company, are or may be
deemed to be as of the time of the Company Shareholders' Meeting "affiliates" of
the Company within the meaning of Rule 145 under the Securities Act and who own
Company Common Stock. There shall be added to such list the names and addresses
of any other Person subsequently identified by either Parent or the Company, as
the case may be (unless, in the case of Parent, an opinion of outside counsel to
the Company reasonably acceptable to Parent is provided to Parent that such
Person is not an affiliate), as a Person who may be deemed to be such an
affiliate; provided, however, that no such Person identified by Parent or the

   Parent Breach exists, and the Company has given Parent notice thereof, the

   8.6 Governing Law. Except as to matters of internal corporation law, which
shall be governed by the laws of the State of North Carolina, in the case of the
Company, New York in the case of Parent and Delaware in the case of Merger Sub,
this Agreement shall be governed and construed in accordance with the laws of

party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in

Election and Letter of Transmittal to the Exchange Agent specified therein,
together with certificates evidencing the Pledged Securities hereunder. The
Pledgor hereby grants the Company and, following the Merger, its successor,
Winston, Inc. power of attorney to endorse the Pledgor's name on any check or
other instrument representing


                                       2
<PAGE>

Merger Payments in order that such Merger Payments may be applied
to prepayment of the Notes in accordance with this Section 2. The Pledgor
further agrees that, should any Merger Payments be paid to the Pledgor in lieu
of the Company at any time when any Note is outstanding, the Pledgor shall hold
such payments in trust for the Company and promptly remit to the Company all
such Merger Payments for application to the prepayment of the Notes. [The
Company and Pledgor acknowledge that the Pledged Securities are subject to that
certain Voting Agreement dated as of October 2, 1998 between the Pledgor, the
Company and AT&T Corp. and covenant to perform the obligations set forth therein
with respect to the Pledged Securities.](2)

     3.     REPRESENTATIONS AND WARRANTIES.  The Pledgor represents and
warrants that the Pledged Securities are, and will be upon deposit hereunder,
duly and validly issued and duly and validly pledged with the Company in
accordance with the law and agrees to defend the Company's right, title, lien
and security interest in and to the Pledged Collateral against the claims and
demands of all persons whomsoever.  The Pledgor also represents and warrants
to the Company that Pledgor has, and will have on deposit hereunder, good title
to all of the Pledged Collateral, free and clear of all options to purchase or
similar rights, claims, mortgages, pledges, liens, encumbrances and security
interests of every nature whatsoever, except those granted to the Company
herein, and that no consent or approval of any governmental or regulatory
authority, or of any securities exchange was or is necessary to the validity of
this pledge. Upon delivery to the Company of the stock certificates described on
Exhibit A and the related blank stock transfer power, Pledgor represents and
warrants that the security interest and lien granted hereunder will constitute a
first priority security interest in and lien on the Pledged Collateral.

      4. TRANSFER UPON DEFAULT.  Upon the occurrence of any default under
any of the Notes (a "Default"), the Company may cause all or any of the
Pledged Securities to be transferred to or registered in its name or the name
of its nominee or nominees.

      5. VOTING RIGHTS. So long as no Default shall have occurred, the Pledgor
shall be entitled to exercise the voting power with respect to the Pledged
Securities as the Pledgor shall think fit, but in a manner not inconsistent with
the terms hereof or of the Notes, and for that purpose the Company shall (if the
Pledged Securities shall be registered in the name of the Company or its
nominee) execute or cause to be executed from time to time, at the expense of
the Pledgor, such proxies or other instruments in favor of the Pledgor, in such
form and for such purposes as shall be reasonably required by the Pledgor and
shall be specified in a written request therefor by the Pledgor to enable the
Pledgor to exercise such voting power with respect to the Pledged Securities.

      6. VOTING RIGHTS UPON DEFAULT. Upon the occurrence and during the
continuance of any Default, the Company shall, to the extent permitted by law,
have the sole and absolute right, in addition to any other rights herein
contained, to exercise all voting power

Pledgors who are founders, and deleted from Pledge Agreements for Pledgors who
are vice presidents.

with respect to the Pledged Securities, and in such event the Pledgor hereby
appoints the Company as the Pledgor's true and lawful proxy to vote such shares
in any manner that the Company deems advisable for or against all matters that
may be submitted to a vote of such shareholders.

      7. DIVIDENDS. (i) In case upon the dissolution or liquidation (in whole or
in part) of the Company, any sum shall be paid as a liquidating dividend or
otherwise upon or with respect to any of the Pledged Securities, and (ii) in
case after a Default any other dividends of any kind shall be paid upon or with
respect to any of the Pledged Securities under any circumstances, such sum shall
be paid over to the Company, to be held by the Company as additional collateral
hereunder. In case any stock dividend shall be declared on any of the Pledged
Securities, or any shares of stock or fractions thereof shall be issued pursuant
to any stock split involving any of the Pledged Securities, or any dividend or
distribution of capital shall be made on any of the Pledged Securities, or any
shares, obligations or other property shall be distributed upon or with respect
to the Pledged Securities pursuant to a recapitalization or reclassification of
the capital of the Borrower, or pursuant to the dissolution, liquidation (in
whole or in part), bankruptcy or reorganization of the Company, or the merger or
consolidation of the Borrower with or into another corporation, then in any such
case the stock dividends, shares of stock or fraction thereof, obligations or
other property so distributed shall be delivered to the Company, to be held by
it as additional collateral hereunder, and all of the same shall constitute
Pledged Collateral for all purposes hereof. Any cash received and retained by
the Company as additional collateral hereunder pursuant to the foregoing
provisions shall be held in an interest-bearing account for the benefit of the
Pledgor and may at any time and from time to time be applied (in whole or in
part) by the Company, at its option, to the payment of the Obligations.
Notwithstanding the foregoing, Merger Payments shall be applied as set forth in
Section 2 hereof.

      8. REMEDIES. Immediately upon the occurrence of a Default, the Company
shall have all rights and remedies of a secured party under the Uniform
Commercial Code as adopted in the State of North Carolina and, without
obligation to resort to other security, shall have the right at any time and
from time to time to sell, resell, assign and deliver, in its discretion, all or
any of the Pledged Collateral, in one or more parcels at the same or different
times, and all right, title and interest, claim and demand therein and right of
redemption thereof, on any securities exchange on which the Pledged Securities
or any of them may be listed, or at public or private sale, for cash, upon
credit or for future delivery, and in connection therewith the Company may grant
options, the Pledgor hereby waiving and releasing any and all equity or right of
redemption. If any of the Pledged Collateral is sold by the Company upon credit
or for future delivery, the Company shall not be liable for the failure of the
purchaser to purchase or pay for the same and in the event of any such failure,
the Company may resell such Pledged Collateral. In no event shall the Pledgor be
credited with any part of the proceeds of sale of any Pledged Collateral until
cash payment of such sale has actually been received by the Company.

      9. SALE OF PLEDGED COLLATERAL; APPLICATION OF PROCEEDS OF SALE. The
Company shall give the Pledgor at least five (5) days' prior notice of the time
and place of any public sale and of the time after which any private sale or
other disposition is to

                                       4
<PAGE>

be made, which notice the Pledgor agrees is reasonable, all other demand,
advertisements and notices being hereby waived. The Company shall not be
obligated to make any sale of Pledged Collateral if it shall determine not to do
so, regardless of the fact that notice of sale may have been given. The Company
may, without notice or publication, adjourn any public or private sale or cause
the same to be adjourned from time to time by announcement at the time and place
fixed for sale; and such sale may, without further notice, be made at the time
and place to which the same was so adjourned. Upon each private sale of Pledged
Collateral of a type customarily sold in a recognized market and upon each
public sale, the Company, or any holder of any of the Obligations, may purchase
all or any of the Pledged Collateral being sold, free from any equity or right
of redemption, which is hereby waived and released by the Pledgor, and may make
payment therefor (by endorsement without recourse) in the Obligations in lieu of
cash to the amount then due thereon, which the Pledgor hereby agrees to accept.
In the case of all sales of Pledged Collateral, public or private, after all
costs and expenses of every kind for sale or delivery, including brokers' and
reasonable attorneys' fees, shall be deducted from the proceeds of the sale, the
Company shall apply any residue to the payment of the Obligations in the order
provided in Section 2 above. The balance, if any, remaining after payment in
full or all of the Obligations, shall be paid to the Pledgor, subject to any
duty of the Company imposed by law to the holder of any subordinate security
interest in the Pledged Securities known to the Company.

      10. PRIVATE SALE. The Pledgor recognizes that the Company may be unable to
effect a public sale of all or a part of the Pledged Securities by reason of
certain prohibitions contained in the Securities Act of 1933, as amended, as now
or hereafter in effect, or in applicable Blue Sky or other state securities
laws, as now or hereafter in effect, but may be compelled to resort to one or
more private sales to a restricted group of purchasers who will be obligated to
agree, among other things, to acquire such Pledged Securities for their own
account, for investment and not with a view to the distribution or resale
thereof. The Pledgor agrees that private sales so made may be at prices and on
other terms less favorable to the seller than if such Pledged Securities were
sold at public sales, and that the Company has no obligation to cause the
registration of such Pledged Securities for public sale under such applicable
securities laws.

     11. CARE OF PLEDGED COLLATERAL. The Company shall have no duty as to the
collection or protection of the Pledged Collateral or any income thereof or as
to the preservation of any rights pertaining thereto, beyond the safe custody of
any Pledged Collateral actually in its possession. The Company shall not have
any responsibility for (i) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, redemptions, offers, tenders or other
matters relative to any Pledged Collateral, whether or not the Company has or is
deemed to have knowledge of such matters, except delivery of the Pledged
Securities as required by the Form of Election and Letter of Transmittal
relating to the Merger, or (ii) taking any necessary steps to preserve rights
against any parties with respect to any Pledged Collateral.

      12. TERMINATION. When all Obligations have been paid in full, this Pledge
Agreement shall terminate and any remaining Pledged Collateral shall revert to
the Pledgor and the right, title and interest of the Company therein shall
terminate. Thereupon, the Company shall redeliver any items of Pledged
Collateral then in its possession.

                                       5
<PAGE>

     13. FURTHER ASSURANCES. The Pledgor shall take such further actions and
execute such further documents and instruments as the Company may reasonably
request in order to effectuate fully the provisions of this Pledge Agreement,
including without limitation the provisions of Section 2 hereof.

     14. INSTRUCTIONS TO EXCHANGE AGENT. Any exchange agent acting in connection
with the Merger may rely on a copy of this Agreement to, and is hereby
authorized and directed to take all action necessary to, give full effect to the
provisions of this Agreement with respect to any proceeds that would be due to
the Pledgor in connection with the Merger. The Pledgor agrees to provide any
further documentation required by such exchange agent to effectuate the
foregoing.

     15. MISCELLANEOUS. This Agreement shall be binding upon, and inure to the
benefit of (i) the parties hereto and their respective heirs, successors and
assigns, including, in the case of the Company, Winston, Inc., provided,
however, that, the Pledgor may not assign his rights or obligations hereunder
without the prior written consent of the Company and (ii) unless that certain
Agreement and Plan of Merger dated as of October 2, 1998, as amended, shall have
been terminated without consummation of the Merger, AT&T Corp., as an intended
third party beneficiary hereof. This Agreement shall be governed by and
construed in accordance with the laws (other than the conflict of laws rules) of
the State of North Carolina.

      IN WITNESS WHEREOF, the parties hereto have executed this Pledge Agreement
as an agreement under seal as of the date first above written.

$__________                                                 December __, 1998

      FOR VALUE RECEIVED, the undersigned ___________________, an individual
residing at _________________________ (the "Maker"), hereby promises to pay to
Vanguard Cellular Systems, Inc., a North Carolina corporation, or its successors
and assigns (the "Holder"), the principal sum of ________________________
DOLLARS ($__________) on or prior to: (i) if the proposed merger of the Holder
into Winston, Inc. (the "Merger") pursuant to that certain Agreement and Plan of
Merger dated as of October 2, 1998, as amended (the "Merger Agreement"), among
AT&T Corp., Winston, Inc. and the Holder shall have been consummated, the 91st
day following the Effective Time (as defined in the Merger Agreement), or (ii)
if the Merger shall not have been consummated, the fifth anniversary of the date
hereof (or if such fifth anniversary is not a business day, the next succeeding
business day). Interest shall be payable on each anniversary of the date hereof
(or if such anniversary is not a business day, the next succeeding business day)
until repayment in full of this Note, and on any stated or accelerated maturity
of this Note, on the unpaid principal balance from the date of this Note through
the payment in full thereof, at a rate of 5.845% per annum, compounded
quarterly. All payments hereunder shall be made to the Holder in cash or other
immediately available funds, or by check or money order payable to the Holder at
Greensboro, North Carolina, or at such other location as the Holder may specify
by notice to the Maker.

      The proceeds of the loan hereunder shall be used solely to pay the
exercise price of nonqualified options to purchase Class A Common Stock, par
value $0.01 per share, of the Holder (the "Common Stock") held by the Maker.

      This Note may be prepaid in part or in full at any time without premium or
penalty and shall be mandatorily prepayable from and to the extent of certain
payments otherwise payable to the Maker in connection with the Merger, as more
fully set forth in: (i) Section 2 of that certain Pledge Agreement of even date
herewith (the "Pledge Agreement") by Maker in favor of the Holder and (ii) that
certain Agreement re Netting of Payments dated _________________ (the "Netting
Agreement") between the Maker and the Holder.

      This Note is secured by the Pledge Agreement, by any past or future pledge
agreement entered into in connection with loans by the Holder to the Maker
relating to option exercises and related tax payments (collectively, the "Pledge
Agreements") and by the securities and other collateral pledged thereunder. This
Note is entitled to the benefits of the Pledge Agreements and the Netting
Agreement.

<PAGE>

      
      At any time prior to the consummation of the Merger (or, if the Merger is
never consummated, then at any time) the liability of the Maker hereunder shall
be limited to the sum of: (i) the amount of any payments to be made by Holder
required to be applied as mandatory prepayments of this Note pursuant to the
Pledge Agreements or the Netting Agreement (without recourse to any other assets
of the Maker), (ii) the Pledged Collateral (as defined in the Pledge Agreements)
(without recourse to any other assets of the Maker) and (iii) with recourse to
the assets of the Maker, an amount equal to 50% of the sum of all obligations
hereunder, including outstanding principal, accrued and unpaid interest, and any
fees and expenses. Notwithstanding the preceding sentence, assuming that the
Merger is consummated, from and after the Effective Time (as defined in the
Agreement and Plan of Merger dated as of October 2, 1998, as amended, among AT&T
Corp., Winston, Inc. and the Holder), the liability and recourse limitations in
the preceding sentence shall terminate and be of no further force and effect,
and this Note shall become fully recourse to the Maker.

      Upon (a) any failure by the Holder to receive any payment of interest
within 10 days of when due or principal within 5 days of maturity or any
accelerated maturity or (b) any personal bankruptcy filing by or against the
Maker or (c) any representation or warranty of the Maker in the Pledge
Agreements proving false in any material respect on the date as of which it was
made or (d) any other violation of the Maker's agreements contained in the
Pledge Agreements or the Netting Agreement, the Holder: (i) may proceed to
protect and enforce its rights hereunder by suit in equity, action at law and/or
other appropriate proceeding, (ii) may, by notice in writing to the Maker (or
his estate, if deceased), declare all or any part of the unpaid balance of this
Note to be immediately due and payable, whereupon such unpaid balance or part
thereof shall become so due and payable without presentation, protest or further
demand or notice of any kind, all of which are hereby waived (provided that, in
the event of the Maker's bankruptcy, the unpaid balance of this Note shall
automatically become due and payable), (iii) may proceed to enforce payment of
this Note in such manner as the Holder may elect, including realization upon any
and all rights in the security granted pursuant to the Pledge Agreements and the
Netting Agreement and (iv) may offset and apply toward the payment of this Note
any indebtedness from the Holder to the Maker, regardless of the adequacy of any
security for this Note.

      If this Note is referred to an attorney for collection, the Maker agrees
to pay the Holder's reasonable attorneys' fees and expenses (which fees shall be
determined in accordance with the normal hourly rates of such attorneys and not
as a percentage of the indebtedness hereunder) in addition to all other sums
owed hereon.

      The Maker waives to the extent not prohibited by applicable law (i) all
presentments, demands for performance, notices of nonperformance, protests,
notices of protest and notices of dishonor, (ii) any requirement of diligence or
promptness on the part of the Holder in the enforcement of its rights under this
Note, (iii) all notices of every kind which may be required to be given by any
statute or rule of law, (iv) any valuation, stay, appraisement or redemption
laws and (v) any defense or setoff or right of setoff of any kind (other than 

                                       2
<PAGE>

      
indefeasible payment in full) which he may now of hereafter have with respect to
his liability under this Note.

      No course of dealing between the Maker and the Holder shall operate as a
waiver of any of the Holder's rights under this Note. No delay or omission on
the part of the Holder in exercising any right under this Note shall operate as
a waiver of such right or any other right hereunder. No amendment or waiver
shall be binding unless in writing and signed by the Holder.

      This Note shall be governed by and construed in accordance with the laws
(other than the conflict of laws provisions) of the State of North Carolina.

      IN WITNESS WHEREOF, the undersigned has executed this instrument of
indebtedness effective the day and year first above written.

                               VOTING AGREEMENT


            VOTING AGREEMENT (the "Agreement"), dated as of December 22,
1998, between the undersigned stockholder ("Stockholder") of Vanguard
Cellular Systems, Inc., a North Carolina corporation (the "Company"), and
AT&T Corp., a New York corporation ("Parent").

            WHEREAS, prior to the execution and delivery of this Agreement,
the Company and Parent have entered into an Agreement and Plan of Merger
dated as of October 2, 1998 (the "Merger Agreement"), providing for the
merger of the Company with and into a wholly-owned subsidiary of Parent (the
"Merger") pursuant to the terms and conditions thereof; and

            WHEREAS, as an inducement and a condition to Parent entering into
the Merger Agreement, various stockholders of the Company signed voting
agreements with Parent, which agreements restrict the transfer of the Class A
Common Stock, par value $0.01 per share, of the Company (the "Common Stock")
owned by such stockholders; and

            WHEREAS, in accordance with such restrictions it is necessary for
Stockholder to sign this Agreement to receive certain shares of the Common
Stock;

            NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

            1.    Representations of Stockholder.  Stockholder represents
that:

            (a)   such Stockholder is or may become the beneficial owner of
the number of shares of Common Stock set forth opposite such Stockholder's
name on Exhibit A (such Stockholder's "Shares");

            (b)   except as may be denoted in Exhibit A, as of the date
hereof such Stockholder does not beneficially own (as such term is defined in
the Securities Exchange Act of 1934, as amended (the "1934 Act")) or own of
record any shares of Common Stock other than such Stockholder's Shares, but
excluding any shares of Common Stock which such Stockholder has the right to
obtain upon the exercise of stock options outstanding on the date hereof;

            (c)   such Stockholder has the right, power and authority to
execute and deliver this Agreement and to perform such Stockholder's
obligations under this Agreement, and this Agreement has been duly executed
and delivered by such Stockholder and constitutes a valid and legally binding
agreement of such Stockholder, enforceable in accordance with its terms; and
such execution, delivery and performance by such Stockholder of this
Agreement will not (i) conflict with, require a consent, waiver or approval
under, or result in a breach of or default under, any of the terms of any
contract, commitment or other obligation (written or oral) to which such
Stockholder is a party or by which such Stockholder is bound; (ii) violate
any order, writ, injunction, decree or statute, or any rule or regulation,
applicable to Stockholder or any of the properties or assets of Stockholder;
or (iii) result in the creation of, or impose any obligation  

<PAGE>

on such Stockholder to create, any Lien (as defined in the Merger Agreement),
charge or other encumbrance of any nature whatsoever upon the Shares, other than
in favor of Parent; and

            (d)   there are no named beneficiaries of the Preyer-Jacobs
Foundation.

            The representations and warranties contained herein shall be made
as of the date hereof and as of each date from the date hereof through and
including the date that the Merger is consummated or this Agreement is
terminated in accordance with its terms.

            2.    Agreement to Vote Shares.  Stockholder shall be present (in
person or by proxy) at and vote his Shares and any New Shares (as defined in
Section 4 hereof), and shall cause any holder of record of his Shares or New
Shares to be present and vote, (a) in favor of adoption and approval of the
Merger Agreement and the Merger (and each other action and transaction
contemplated by the Merger Agreement or by this Agreement) and (b) against
any Acquisition Proposal (as defined in the Merger Agreement) other than the
Merger (or any other Acquisition Proposal of Parent) and against any proposed
action or transaction that would prevent or intentionally delay consummation
of the Merger (or other Acquisition Proposal of Parent) or is otherwise
inconsistent therewith at every meeting of the stockholders of the Company at
which any such matters are considered and at every adjournment thereof (and,
if applicable, in connection with any request or solicitation of written
consents of stockholders).  Any such vote shall be cast, or consent shall be
given, in accordance with such procedures relating thereto as shall ensure
that it is duly counted for purposes of determining that a quorum is present
and for purposes of recording the results of such vote or consent.
Stockholder shall deliver to Parent upon request a proxy substantially in the
form attached hereto as Exhibit B, which proxy shall be coupled with an
interest and irrevocable to the extent permitted under North Carolina law,
with the total number of such Stockholder's Shares and any New Shares
correctly indicated thereon.  Stockholder hereby revokes any and all previous
proxies granted with respect to his Shares.  Stockholder shall also use his
reasonable best efforts to take, or cause to be taken, all action, and do, or
cause to be done, all things necessary or advisable in order to consummate
and make effective the transactions contemplated by this Agreement.

            3.    No Voting Trusts.  After the date hereof, Stockholder
agrees that he will not, nor will he permit any entity under his control to,
deposit any Shares in a voting trust or subject any Shares to any Lien or
agreement, arrangement or understanding with respect to the voting of such
Shares other than agreements entered into with Parent.

            4.    Additional Purchases.  Stockholder agrees that in the event
(a) of any stock dividend, stock split, recapitalization, reclassification,
combination or exchange of shares of stock of the Company on, of or affecting
the Shares of such Stockholder, (b) such Stockholder purchases or otherwise
acquires beneficial ownership of any shares of Common Stock after the
execution of this Agreement (including by exercise of options), or (c) such
Stockholder acquires the right to vote or share in the voting of any shares
of Common Stock other than the Shares (collectively, "New Shares"), such
Stockholder shall deliver promptly to Parent upon request an irrevocable
proxy substantially in the form attached hereto as Exhibit B with respect to
such New 

                                      -2-
<PAGE>

Shares. Stockholder also agrees that any New Shares acquired or purchased by him
shall be subject to the terms of this Agreement and shall constitute Shares to
the same extent as if they were owned by such Stockholder on the date hereof.

            5.    Option Shares.

            (a)   Subject to the terms and conditions set forth herein,
Stockholder hereby grants to Parent an irrevocable option (the "Option") to
purchase, in whole or in part, such Stockholder's Shares and such
Stockholder's New Shares at a purchase price equal to the Per Share Cash
Amount (as defined in the Merger Agreement) per share; provided, however,
that if the Per Share Cash Amount under the Merger Agreement or any amendment
thereto is ever increased or if Parent shall otherwise offer to the
Stockholders of the Company an increased consideration for all of their
shares (the "Greater Consideration"), then the purchase price per share under
the Option shall be increased to equal such new Per Share Cash Amount or
Greater Consideration; and provided further that if Parent has exercised the
Option within 12 months prior to such increase in the Per Share Cash Amount
or Greater Consideration, then Parent shall pay to each Stockholder an amount
equal to the product of the number of shares previously purchased from such
Stockholder pursuant to the Option and the amount of increase between the old
Per Share Cash Amount and the new Per Share Cash Amount or Greater
Consideration, as applicable.

            (b)   Parent may exercise the Option, in whole or in part, at any
time and from time to time, after the first to occur of (i) any event as a
result of which Parent shall be entitled to receive a termination fee
pursuant to Section 7.2(e) of the Merger Agreement in the amount of $52.5
million pursuant to part (1) or part (2) of such Section or in the amount of
$22.5 million pursuant to part (3) of such Section or (ii) the breach by any
Stockholder of Section 2 of this Agreement (the first of such events to
occur, a "Purchase Event"); provided, however, that except as provided in the
last sentence of this Section 5(b), the Option shall terminate and be of no
further force and effect upon the earliest to occur of (A) the Effective Time
(as defined in the Merger Agreement), (B) 12 months and one day after the
occurrence of a termination of the Merger Agreement in accordance with
Section 7.1 (d), (e), (f) or (g), (C) a termination of the Merger Agreement
in accordance with Section 7.1(a), (b), (c) or (h) of the Merger Agreement
and (D) 18 months after the Outside Date as defined in Section 7.1(e) of the
Merger Agreement.  Notwithstanding the termination of the Option, Parent
shall be entitled to exercise the Option or receive the Cash Payment Amount
if it has given written notice of its intent to exercise the Option or
receive the Cash Payment Amount in accordance with the terms hereof prior to
the termination of the Option and the termination of the Option shall not
affect any rights hereunder which by their terms do not terminate or expire
prior to or as of such termination.

            (c)   In the event that Parent wishes to exercise the Option, it
shall send to such Stockholder a written notice (the date of which being
herein referred to as the "Notice Date") to that effect which notice also
specifies the total number of shares Parent will purchase pursuant to such
exercise, and a date not earlier than three business days nor later than 15
business days from the Notice Date for the closing of such purchase (the
"Option Closing Date"); provided, however, that (i) if the closing of the
purchase and sale pursuant to the Option (the "Option 

                                      -3-
<PAGE>

Closing") cannot be consummated by reason of any applicable judgment, decree,
order, law or regulation (including, without limitation, the rules and
regulations of the FCC), the period of time that otherwise would run pursuant to
this sentence shall run instead from the date on which such restriction on
consummation has expired or been terminated and (ii) without limiting the
foregoing, if prior notification to or approval of any Governmental Entity (as
defined in the Merger Agreement) is required in connection with such purchase or
any other transaction contemplated hereby, Parent and such Stockholder shall
promptly file the required notice or application for approval and shall
cooperate in the expeditious filing of such notice or application, and, in the
case of any prior notification or approval required in connection with such
purchase, the period of time that otherwise would run pursuant to this sentence
shall run instead from the date on which, as the case may be, (A) any required
notification period has expired or been terminated or (B) any required approval
has been obtained, and in either event, any requisite waiting period has expired
or been terminated. The place of the Option Closing shall be at the offices of
Wachtell, Lipton, Rosen & Katz, 51 West 52nd Street, New York, New York, and the
time of the Option Closing shall be 10:00 a.m. (Eastern Time) on the Option
Closing Date.

            (d)   At the Option Closing, Parent (or its designee) shall pay
to each Stockholder an amount equal to the product of (x) the Per Share Cash
Amount or Greater Consideration, as applicable, and (y) the number of shares
being purchased from such Stockholder pursuant to the exercise of the
Option.  Such payment shall be in immediately available funds by wire
transfer to a bank account designated in writing by such Stockholder.

            (e)   At the Option Closing, simultaneously with the delivery of
the amount specified in Section 5(d), each Stockholder shall deliver to
Parent (or its designee) a certificate or certificates representing its
shares to be purchased at the Option Closing, which shares shall be free and
clear of all Liens, claims, charges and encumbrances of any kind whatsoever,
except for such encumbrances or proxies in favor of Parent arising hereunder,
and a new Option evidencing the rights of the Parent (or its designee) to
purchase the balance of such Stockholder's shares purchasable hereunder.

            6.    Cash Election.

            (a)   In lieu of exercising the Option, by notice, Parent may
require such Stockholder to make a cash payment to Parent in the amount (the
"Cash Payment Amount") equal to the amount by which (A) the Market Price (as
defined below) exceeds (B) the Per Share Cash Amount, multiplied by the sum
of (i) the number of such Stockholder's Shares and (ii) the number of such
Stockholder's New Shares.  Upon receipt of such notice, the Stockholder shall
be permitted to sell a sufficient number of Shares to pay the Cash Payment
Amount, if Stockholder shall, within five business days of such notice, sell
such Shares, provided that Stockholder shall use reasonable best efforts to
achieve good execution and shall consult with Parent with respect to the
manner of disposition.  The term "Market Price" shall mean the closing price
(as measured by the last completed trade) for shares of Common Stock on the
date of Parent's election, or if Stockholder elects to sell Shares to pay the
Cash Payment Amount and has complied with the 

                                     -4-

<PAGE>

proviso to the immediately preceding sentence, the average price per Share
actually realized in such sale.

            (b)   Parent may exercise its right to require such Stockholder
to pay the Cash Payment Amount pursuant to this Section by surrendering for such
purpose to such Stockholder, at the Company's principal office, a copy of this
Agreement, accompanied by a written notice or notices stating that Parent elects
to require such Stockholder to pay the Cash Payment Amount in accordance with
the provisions of this Section. Within five(or, in the case of a sale of Shares
under (a) above to fund the Cash Payment Amount, eight) business days after the
surrender of the Option and the receipt of such notice or notices relating
thereto, such Stockholder shall deliver or cause to be delivered to Parent the
Cash Payment Amount by wire to the account designated by Parent in immediately
available funds.

            (c)   If Stockholder at any time after delivery of a notice of
election by Parent to take the Cash Payment Amount pursuant to this Section
is prohibited under applicable law or regulation from selling Shares in order
to deliver to Parent the Cash Payment Amount in full, and Stockholder is
required to sell Shares to fund the Cash Payment Amount, then (i) such
Stockholder hereby undertakes to use such Stockholder's reasonable best
efforts, to the extent within the control of such Stockholder, to obtain all
required regulatory and legal approvals and to file any required notices, in
each case as promptly as practicable in order to accomplish such sales and
(ii) if Stockholder is unable to effect sales within four days after the
receipt of notice, such Stockholder shall be permitted to pay the Cash
Payment Amount to Parent in Shares valued at the Market Price.

            7.    No Encumbrances.

            (a)   Except as expressly contemplated by this Agreement,
Stockholder's Shares and the certificates representing such Shares are now,
and at all times during the term hereof will be, held by such Stockholder, or
by a nominee or custodian for the benefit of such Stockholder, free and clear
of all liens, claims, security interests, proxies, voting trusts or
agreements, understandings or arrangements or any other encumbrances
whatsoever (other than to the extent set forth on Schedule 1 to this
Agreement), except for any such encumbrances or proxies arising hereunder.

            (b)   Notwithstanding the foregoing, any Stockholder which has
received a notice of election by Parent (or its designee) to receive the Cash
Payment Amount shall be permitted, between receipt of such notice and the
time on which the Cash Payment Amount is due to be paid, to sell such number
of Shares as may be necessary to satisfy such obligation, as described in
Section 6(a) above.

            (c)   Any transfer by Stockholder of its Shares to Parent
pursuant to the Option shall pass to and unconditionally vest in Parent good
and valid title to such Stockholder's Shares and New Shares, free and clear
of all claims, liens, restrictions, security interests, pledges, limitations
and encumbrances whatsoever.


                                      -5-
   

<PAGE>

         8.    Acquisition Proposals.  Stockholder agrees that such
Stockholder (i) shall not, directly or indirectly, initiate, solicit, encourage
or otherwise facilitate any inquiries or the making of any Acquisition Proposal
and (ii) has terminated any discussions or negotiations with, and the provision
of information or data to, any Person (other than Parent) respecting an
Acquisition Proposal. Such Stockholder further agrees that he shall not,
directly or indirectly, provide any confidential information or data to any
Person (as defined in the Merger Agreement) relating to or in contemplation of
an Acquisition Proposal or engage in any negotiations or discussions relating to
or in contemplation of an Acquisition Proposal. Such Stockholder will notify
Parent immediately if any inquiries, proposals or offers respecting an
Acquisition Proposal are received by, any such information or data is requested
from, or any such discussions or negotiations are sought to be initiated or
continued with, such Stockholder indicating, in connection with such notice, the
name of such Person and the material terms and conditions of any proposals or
offers, and shall keep Parent apprised with respect to the status and terms
thereof.

            9.    Appraisal Rights.  Stockholder agrees not to exercise any
rights (including, without limitation, under Article 13 of the North Carolina
Business Corporation Act) to demand appraisal of any Common Stock which may
arise with respect to the Merger.

            10.   Affiliates Letter.  Stockholder shall execute and deliver
on a timely basis an Affiliate Letter (as defined in the Merger Agreement).

            11.   Reliance by Parent.  Stockholder understands and
acknowledges that Parent is entering into the Merger Agreement in reliance
upon Stockholder's execution and delivery of this Agreement.

            12.   Specific Performance.  Each party hereto severally
acknowledges that it will be impossible to measure in money the damage to the
other parties if the party hereto fails to comply with any of the obligations
imposed by this Agreement, that every such obligation is material and that,
in the event of any such failure, the other parties will not have an adequate
remedy at law or damages.  Accordingly, each party hereto severally agrees
that injunctive relief or other equitable remedy, in addition to remedies at
law or damages, is the appropriate remedy for any such failure and will not
oppose the granting of such relief on the basis that any other party has an
adequate remedy at law.  Each party hereto severally agrees that it will not
seek, and agrees to waive any requirement for, the securing or posting of a
bond in connection with any other party's seeking or obtaining such equitable
relief.

            13.   Heirs, Successors and Assigns.  This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their
respective heirs, successors and assigns and shall not be assignable without
the written consent of all other parties hereto other than any assignment in
whole or in part by Parent.

            14.   Entire Agreement.  This Agreement supersedes all prior
agreements, written or oral, among the parties hereto with respect to the
subject matter hereof and contains the entire agreement among the parties
with respect to the subject matter hereof.  This Agreement may not be
amended, supplemented or modified, and no provisions hereof may be modified
or 

                                      -6-

waived, except by an instrument in writing signed by all the parties hereto. No
waiver of any provisions hereof by any party shall be deemed a waiver of any
other provisions hereof by any such party, nor shall any such waiver be deemed a
continuing waiver of any provision hereof by such party.


            15.   Miscellaneous.

            (a)   Expenses.  Each of the parties hereto shall bear and pay
all costs and expenses incurred by it or on its behalf in connection with the
negotiation of this Agreement, including fees and expenses of its own
financial consultants, investment bankers, accountants and counsel.

            (b)   Amendment.  This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

            (c)   This Agreement shall be deemed a contract made under, and
for all purposes shall be construed in accordance with, the internal laws of
the State of New York without regard to principles of conflicts of law,
except for those provisions relating to the voting and the proxy which shall
be governed by North Carolina law.

            (d)   Severability.  If any provision of this Agreement or the
application of such provision to any person or circumstances shall be held
invalid by a court of competent jurisdiction, the remainder of the provision
held invalid and the application of such provision to persons or
circumstances, other than the party as to which it is held invalid, shall not
be affected.

            (e)   Counterparts.  This Agreement may be executed in one or
more counterparts, each of which shall be deemed to be an original but all of
which together shall constitute one and the same instrument.

            (f)   Termination.  This Agreement shall terminate upon
termination of the Option.

            (g)   Headings.  All Section headings herein are for convenience
of reference only and are not part of this Agreement and no construction or
reference shall be derived therefrom.

            (h)   Notices.  All notices, requests, claims, demands, and other
communications under this Agreement must be in writing and shall be deemed

                                FORM OF PROXY


            The undersigned stockholder, for consideration received, hereby
appoints [PARENT DESIGNEES] and each of them as my proxies, with full power
of substitution in each of them, to cast on behalf of the undersigned all
votes entitled to be cast by the holder of the shares of Class A Common
Stock, par value $0.01 per share, of Vanguard Cellular Systems, Inc., a North
Carolina corporation (the "Company"), owned by the undersigned at the Special
Meeting of Stockholders of the Company to be held [DATE, TIME AND PLACE] and
at any adjournment thereof (i) "FOR" approval and adoption of the Agreement
and Plan of Merger, dated as of October 2, 1998, between the Company and AT&T
Corp., a New York corporation ("Parent"), providing for the merger (the
"Merger") of the Company with and into a wholly-owned subsidiary of Parent,
and the Merger and (ii) "AGAINST" any proposal or offer with respect to a
merger, reorganization, share exchange, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving,
or any purchase of any substantial portion of the assets of, or any equity
securities of, or any transaction that would involve the transfer or
potential transfer of control of, the Company other than the Merger and any
proposed action or transaction that would prevent or intentionally delay
consummation of the Merger or is otherwise inconsistent therewith.  This
proxy is coupled with an interest and is irrevocable until such time as the
Voting Agreement, dated as of December 22, 1998, between a certain
stockholder of the Company, the undersigned, and Parent terminates in
accordance with its terms.

                                    Dated _____________________, 1998

<PAGE>
                                VOTING AGREEMENT


            VOTING AGREEMENT (the "Agreement"), dated as of December 22, 1998,
between the undersigned stockholder ("Stockholder") of Vanguard Cellular
Systems, Inc., a North Carolina corporation (the "Company"), and AT&T Corp., a
New York corporation ("Parent").

            WHEREAS, prior to the execution and delivery of this Agreement, the
Company and Parent have entered into an Agreement and Plan of Merger dated as of
October 2, 1998 (the "Merger Agreement"), providing for the merger of the
Company with and into a wholly-owned subsidiary of Parent (the "Merger")
pursuant to the terms and conditions thereof; and

            WHEREAS, as an inducement and a condition to Parent entering into
the Merger Agreement, various stockholders of the Company signed voting
agreements with Parent, which agreements restrict the transfer of the Class A
Common Stock, par value $0.01 per share, of the Company (the "Common Stock")
owned by such stockholders; and

            WHEREAS, in accordance with such restrictions it is necessary for
Stockholder to sign this Agreement to receive certain shares of the Common
Stock;

            NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

            1.    Representations of Stockholder.  Stockholder represents
that:

            (a)   such Stockholder is or may become the beneficial owner of the
number of shares of Common Stock set forth opposite such Stockholder's name on
Exhibit A (such Stockholder's "Shares");

            (b)   except as may be denoted in Exhibit A, as of the date hereof
such Stockholder does not beneficially own (as such term is defined in the
Securities Exchange Act of 1934, as amended (the "1934 Act")) or own of record
any shares of Common Stock other than such Stockholder's Shares, but excluding
any shares of Common Stock which such Stockholder has the right to obtain upon
the exercise of stock options outstanding on the date hereof;

            (c)   such Stockholder has the right, power and authority to execute
and deliver this Agreement and to perform such Stockholder's obligations under
this Agreement, and this Agreement has been duly executed and delivered by such
Stockholder and constitutes a valid and legally binding agreement of such
Stockholder, enforceable in accordance with its terms; and such execution,
delivery and performance by such Stockholder of this Agreement will not (i)
conflict with, require a consent, waiver or approval under, or result in a
breach of or default under, any of the terms of any contract, commitment or
other obligation (written or oral) to which such Stockholder is a party or by
which such Stockholder is bound; (ii) violate any order, writ, injunction,
decree or statute, or any rule or regulation, applicable to Stockholder or any
of the properties or assets of Stockholder; or (iii) result in the creation of,
or impose any obligation





<PAGE>


on such Stockholder to create, any Lien (as defined in the Merger Agreement),
charge or other encumbrance of any nature whatsoever upon the Shares, other than
in favor of Parent; and

            (d)   there are no named beneficiaries of the Leeolou Family
Foundation.

            The representations and warranties contained herein shall be made as
of the date hereof and as of each date from the date hereof through and
including the date that the Merger is consummated or this Agreement is
terminated in accordance with its terms.

            2.    Agreement to Vote Shares. Stockholder shall be present (in
person or by proxy) at and vote his Shares and any New Shares (as defined in
Section 4 hereof), and shall cause any holder of record of his Shares or New
Shares to be present and vote, (a) in favor of adoption and approval of the
Merger Agreement and the Merger (and each other action and transaction 
contemplated by the Merger Agreement or by this Agreement) and (b) against any
Acquisition Proposal (as defined in the Merger Agreement) other than the Merger
(or any other Acquisition Proposal of Parent) and against any proposed action or
transaction that would prevent or intentionally delay consummation of the Merger
(or other Acquisition Proposal of Parent) or is otherwise inconsistent therewith
at every meeting of the stockholders of the Company at which any such matters
are considered and at every adjournment thereof (and, if applicable, in 
connection with any request or solicitation of written consents of stock-
holders). Any such vote shall be cast, or consent shall be given, in accordance
with such procedures relating thereto as shall ensure that it is duly counted
for purposes of determining that a quorum is present and for purposes of
recording the results of such vote or consent. Stockholder shall deliver to
Parent upon request a proxy substantially in the form attached hereto as Exhibit
B, which proxy shall be coupled with an interest and irrevocable to the extent
permitted under North Carolina law, with the total number of such Stockholder's
Shares and any New Shares correctly indicated thereon. Stockholder hereby
revokes any and all previous proxies granted with respect to his Shares. 
Stockholder shall also use his reasonable best efforts to take, or cause to be
taken, all action, and do, or cause to be done, all things necessary or 
advisable in order to consummate and make effective the transactions 
contemplated by this Agreement.

            3.    No Voting Trusts. After the date hereof, Stockholder agrees
that he will not, nor will he permit any entity under his control to, deposit
any Shares in a voting trust or subject any Shares to any Lien or agreement,
arrangement or understanding with respect to the voting of such Shares other
than agreements entered into with Parent.

            4.    Additional Purchases. Stockholder agrees that in the event (a)
of any stock dividend, stock split, recapitalization, reclassification, 
combination or exchange of shares of stock of the Company on, of or affecting 
the Shares of such Stockholder, (b) such Stockholder purchases or otherwise 
acquires beneficial ownership of any shares of Common Stock after the execution
of this Agreement (including by exercise of options), or (c) such Stockholder
acquires the right to vote or share in the voting of any shares of Common Stock
other than the Shares (collectively, "New Shares"), such Stockholder shall 
deliver promptly to Parent upon request an irrevocable proxy substantially in 
the form attached hereto as Exhibit B with respect to such New




                                      -2-


<PAGE>


Shares. Stockholder also agrees that any New Shares acquired or purchased by him
shall be subject to the terms of this Agreement and shall constitute Shares to
the same extent as if they were owned by such Stockholder on the date hereof.

            5.    Option Shares.

            (a)   Subject to the terms and conditions set forth herein,
Stockholder hereby grants to Parent an irrevocable option (the "Option") to
purchase, in whole or in part, such Stockholder's Shares and such Stockholder's
New Shares at a purchase price equal to the Per Share Cash Amount (as defined in
the Merger Agreement) per share; provided, however, that if the Per Share Cash
Amount under the Merger Agreement or any amendment thereto is ever increased or
if Parent shall otherwise offer to the Stockholders of the Company an increased
consideration for all of their shares (the "Greater Consideration"), then the
purchase price per share under the Option shall be increased to equal such new
Per Share Cash Amount or Greater Consideration; and provided further that if
Parent has exercised the Option within 12 months prior to such increase in the
Per Share Cash Amount or Greater Consideration, then Parent shall pay to each
Stockholder an amount equal to the product of the number of shares previously
purchased from such Stockholder pursuant to the Option and the amount of
increase between the old Per Share Cash Amount and the new Per Share Cash Amount
or Greater Consideration, as applicable.

            (b)   Parent may exercise the Option, in whole or in part, at any 
time and from time to time, after the first to occur of (i) any event as a
result of which Parent shall be entitled to receive a termination fee pursuant
to Section 7.2(e) of the Merger Agreement in the amount of $52.5 million
pursuant to part (1) or part (2) of such Section or in the amount of $22.5
million pursuant to part (3) of such Section or (ii) the breach by any
Stockholder of Section 2 of this Agreement (the first of such events to occur, a
"Purchase Event"); provided, however, that except as provided in the last
sentence of this Section 5(b), the Option shall terminate and be of no further
force and effect upon the earliest to occur of (A) the Effective Time (as
defined in the Merger Agreement), (B) 12 months and one day after the occurrence
of a termination of the Merger Agreement in accordance with Section 7.1 (d),
(e), (f) or (g), (C) a termination of the Merger Agreement in accordance with
Section 7.1(a), (b), (c) or (h) of the Merger Agreement and (D) 18 months after
the Outside Date as defined in Section 7.1(e) of the Merger Agreement.
Notwithstanding the termination of the Option, Parent shall be entitled to
exercise the Option or receive the Cash Payment Amount if it has given written
notice of its intent to exercise the Option or receive the Cash Payment Amount
in accordance with the terms hereof prior to the termination of the Option and
the termination of the Option shall not affect any rights hereunder which by
their terms do not terminate or expire prior to or as of such termination.

            (c)   In the event that Parent wishes to exercise the Option, it 
shall send to such Stockholder a written notice (the date of which being herein
referred to as the "Notice Date") to that effect which notice also specifies the
total number of shares Parent will purchase pursuant to such exercise, and a
date not earlier than three business days nor later than 15 business days from
the Notice Date for the closing of such purchase (the "Option Closing Date");
provided, however, that (i) if the closing of the purchase and sale pursuant to
the Option (the "Option




                                      -3-



<PAGE>


Closing") cannot be consummated by reason of any applicable judgment, decree,
order, law or regulation (including, without limitation, the rules and
regulations of the FCC), the period of time that otherwise would run pursuant to
this sentence shall run instead from the date on which such restriction on
consummation has expired or been terminated and (ii) without limiting the
foregoing, if prior notification to or approval of any Governmental Entity (as
defined in the Merger Agreement) is required in connection with such purchase or
any other transaction contemplated hereby, Parent and such Stockholder shall
promptly file the required notice or application for approval and shall
cooperate in the expeditious filing of such notice or application, and, in the
case of any prior notification or approval required in connection with such
purchase, the period of time that otherwise would run pursuant to this sentence
shall run instead from the date on which, as the case may be, (A) any required
notification period has expired or been terminated or (B) any required approval
has been obtained, and in either event, any requisite waiting period has expired
or been terminated. The place of the Option Closing shall be at the offices of
Wachtell, Lipton, Rosen & Katz, 51 West 52nd Street, New York, New York, and the
time of the Option Closing shall be 10:00 a.m. (Eastern Time) on the Option
Closing Date.

            (d)   At the Option Closing, Parent (or its designee) shall pay to
each Stockholder an amount equal to the product of (x) the Per Share Cash Amount
or Greater Consideration, as applicable, and (y) the number of shares being
purchased from such Stockholder pursuant to the exercise of the Option. Such
payment shall be in immediately available funds by wire transfer to a bank
account designated in writing by such Stockholder.

            (e)   At the Option Closing, simultaneously with the delivery of the
amount specified in Section 5(d), each Stockholder shall deliver to Parent (or
its designee) a certificate or certificates representing its shares to be
purchased at the Option Closing, which shares shall be free and clear of all
Liens, claims, charges and encumbrances of any kind whatsoever, except for such
encumbrances or proxies in favor of Parent arising hereunder, and a new Option
evidencing the rights of the Parent (or its designee) to purchase the balance of
such Stockholder's shares purchasable hereunder.

            6.    Cash Election.

            (a)   In lieu of exercising the Option, by notice, Parent may 
require such Stockholder to make a cash payment to Parent in the amount (the
"Cash Payment Amount") equal to the amount by which (A) the Market Price (as
defined below) exceeds (B) the Per Share Cash Amount, multiplied by the sum of
(i) the number of such Stockholder's Shares and (ii) the number of such
Stockholder's New Shares. Upon receipt of such notice, the Stockholder shall be
permitted to sell a sufficient number of Shares to pay the Cash Payment Amount,
if Stockholder shall, within five business days of such notice, sell such
Shares, provided that Stockholder shall use reasonable best efforts to achieve
good execution and shall consult with Parent with respect to the manner of
disposition. The term "Market Price" shall mean the closing price (as measured
by the last completed trade) for shares of Common Stock on the date of Parent's
election, or if Stockholder elects to sell Shares to pay the Cash Payment Amount
and has complied with the




                                      -4-



<PAGE>


proviso to the immediately preceding sentence, the average price per Share
actually realized in such sale.

            (b)   Parent may exercise its right to require such Stockholder to
pay the Cash Payment Amount pursuant to this Section by surrendering for such
purpose to such Stockholder, at the Company's principal office, a copy of this
Agreement, accompanied by a written notice or notices stating that Parent elects
to require such Stockholder to pay the Cash Payment Amount in accordance with
the provisions of this Section. Within five (or, in the case of a sale of Shares
under (a) above to fund the Cash Payment Amount, eight) business days after the
surrender of the Option and the receipt of such notice or notices relating
thereto, such Stockholder shall deliver or cause to be delivered to Parent the
Cash Payment Amount by wire to the account designated by Parent in immediately
available funds.

            (c)   If Stockholder at any time after delivery of a notice of
election by Parent to take the Cash Payment Amount pursuant to this Section is
prohibited under applicable law or regulation from selling Shares in order to
deliver to Parent the Cash Payment Amount in full, and Stockholder is required
to sell Shares to fund the Cash Payment Amount, then (i) such Stockholder hereby
undertakes to use such Stockholder's reasonable best efforts, to the extent
within the control of such Stockholder, to obtain all required regulatory and
legal approvals and to file any required notices, in each case as promptly as
practicable in order to accomplish such sales and (ii) if Stockholder is unable
to effect sales within four days after the receipt of notice, such Stockholder
shall be permitted to pay the Cash Payment Amount to Parent in Shares valued at

            7.    No Encumbrances.

            (a)   Except as expressly contemplated by this Agreement,

            8.    Acquisition Proposals. Stockholder agrees that such Stock-
holder (i) shall not, directly or indirectly, initiate, solicit, encourage or
otherwise facilitate any inquiries or the making of any Acquisition Proposal and
(ii) has terminated any discussions or negotiations with, and the provision of
information or data to, any Person (other than Parent) respecting an Acquisition
Proposal. Such Stockholder further agrees that he shall not, directly or
indirectly, provide any confidential information or data to any Person (as
defined in the Merger Agreement) relating to or in contemplation of an
Acquisition Proposal or engage in any negotiations or discussions relating to or
in contemplation of an Acquisition Proposal. Such Stockholder will notify Parent
immediately if any inquiries, proposals or offers respecting an Acquisition
Proposal are received by, any such information or data is requested from, or any
such discussions or negotiations are sought to be initiated or continued with,
such Stockholder indicating, in connection with such notice, the name of such
Person and the material terms and conditions of any proposals or offers, and
shall keep Parent apprised with respect to the status and terms thereof.

            9.    Appraisal Rights. Stockholder agrees not to exercise any

that it will be impossible to measure in money the damage to the other parties
if the party hereto fails to comply with any of the obligations imposed by this
Agreement, that every such obligation is material and that, in the event of any
such failure, the other parties will not have an adequate remedy at law or
damages. Accordingly, each party hereto severally agrees that injunctive relief
or other equitable remedy, in addition to remedies at law or damages, is the
appropriate remedy for any such failure and will not oppose the granting of such
relief on the basis that any other party has an adequate remedy at law. Each
party hereto severally agrees that it will not seek, and agrees to waive any
requirement for, the securing or posting of a bond in connection with any other
party's seeking or obtaining such equitable relief.

            13.   Heirs, Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective heirs,
successors and assigns and shall not be assignable without the written consent
of all other parties hereto other than any assignment in whole or in part by
Parent.

            14.   Entire Agreement. This Agreement supersedes all prior
agreements, written or oral, among the parties hereto with respect to the
subject matter hereof and contains the entire agreement among the parties with
respect to the subject matter hereof. This Agreement may not be amended,
supplemented or modified, and no provisions hereof may be modified or




                                      -6-


<PAGE>


waived, except by an instrument in writing signed by all the parties hereto. No
waiver of any provisions hereof by any party shall be deemed a waiver of any
other provisions hereof by any such party, nor shall any such waiver be deemed a
continuing waiver of any provision hereof by such party.

            15.   Miscellaneous.

            (a)   Expenses. Each of the parties hereto shall bear and pay all
costs and expenses incurred by it or on its behalf in connection with the
negotiation of this Agreement, including fees and expenses of its own financial
consultants, investment bankers, accountants and counsel.

            (b)   Amendment. This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

            (c)   This Agreement shall be deemed a contract made under, and for
all purposes shall be construed in accordance with, the internal laws of the
State of New York without regard to principles of conflicts of law, except for
those provisions relating to the voting and the proxy which shall be governed by
North Carolina law.

            (d)   Severability. If any provision of this Agreement or the
application of such provision to any person or circumstances shall be held
invalid by a court of competent jurisdiction, the remainder of the provision
held invalid and the application of such provision to persons or circumstances,
other than the party as to which it is held invalid, shall not be affected.

                                  FORM OF PROXY


            The undersigned stockholder, for consideration received, hereby
appoints [PARENT DESIGNEES] and each of them as my proxies, with full power of
substitution in each of them, to cast on behalf of the undersigned all votes
entitled to be cast by the holder of the shares of Class A Common Stock, par
value $0.01 per share, of Vanguard Cellular Systems, Inc., a North Carolina
corporation (the "Company"), owned by the undersigned at the Special Meeting of
Stockholders of the Company to be held [DATE, TIME AND PLACE] and at any
adjournment thereof (i) "FOR" approval and adoption of the Agreement and Plan of
Merger, dated as of October 2, 1998, between the Company and AT&T Corp., a New
York corporation ("Parent"), providing for the merger (the "Merger") of the
Company with and into a wholly-owned subsidiary of Parent, and the Merger and
(ii) "AGAINST" any proposal or offer with respect to a merger, reorganization,
share exchange, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving, or any purchase of
any substantial portion of the assets of, or any equity securities of, or any
transaction that would involve the transfer or potential transfer of control of,
the Company other than the Merger and any proposed action or transaction that
would prevent or intentionally delay consummation of the Merger or is otherwise
inconsistent therewith. This proxy is coupled with an interest and is
irrevocable until such time as the Voting Agreement, dated as of December 22,
1998, between a certain stockholder of the Company, the undersigned, and Parent
terminates in accordance with its terms.

                               VOTING AGREEMENT


            VOTING AGREEMENT (the "Agreement"), dated as of December 22, 1998,
between the undersigned stockholder ("Stockholder") of Vanguard Cellular
Systems, Inc., a North Carolina corporation (the "Company"), and AT&T Corp., a
New York corporation ("Parent").

            WHEREAS, prior to the execution and delivery of this Agreement, the
Company and Parent have entered into an Agreement and Plan of Merger dated as of
October 2, 1998 (the "Merger Agreement"), providing for the merger of the
Company with and into a wholly-owned subsidiary of Parent (the "Merger")
pursuant to the terms and conditions thereof; and

            WHEREAS, as an inducement and a condition to Parent entering into
the Merger Agreement, various stockholders of the Company signed voting
agreements with Parent, which agreements restrict the transfer of the Class A
Common Stock, par value $0.01 per share, of the Company (the "Common Stock")
owned by such stockholders; and

            WHEREAS, in accordance with such restrictions it is necessary for
Stockholder to sign this Agreement to receive certain shares of the Common
Stock;

            NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

            1.    Representations of Stockholder.  Stockholder represents
that:

            (a)   such Stockholder is or may become the beneficial owner of the
number of shares of Common Stock set forth opposite such Stockholder's name on
Exhibit A (such Stockholder's "Shares");

            (b)   except as may be denoted in Exhibit A, as of the date hereof
such Stockholder does not beneficially own (as such term is defined in the
Securities Exchange Act of 1934, as amended (the "1934 Act")) or own of record
any shares of Common Stock other than such Stockholder's Shares, but excluding
any shares of Common Stock which such Stockholder has the right to obtain upon
the exercise of stock options outstanding on the date hereof;

            (c)   such Stockholder has the right, power and authority to execute
and deliver this Agreement and to perform such Stockholder's obligations under
this Agreement, and this Agreement has been duly executed and delivered by such
Stockholder and constitutes a valid and legally binding agreement of such
Stockholder, enforceable in accordance with its terms; and such execution,
delivery and performance by such Stockholder of this Agreement will not (i)
conflict with, require a consent, waiver or approval under, or result in a
breach of or default under, any of the terms of any contract, commitment or
other obligation (written or oral) to which such Stockholder is a party or by
which such Stockholder is bound; (ii) violate any order, writ, injunction,
decree or statute, or any rule or regulation, applicable to Stockholder or any
of the properties or assets of Stockholder; or (iii) result in the creation of,
or impose any obligation




<PAGE>

on such Stockholder to create, any Lien (as defined in the Merger Agreement),
charge or other encumbrance of any nature whatsoever upon the Shares, other than
in favor of Parent; and

            (d)   there are no named beneficiaries of the Griffin Family
Foundation.

            The representations and warranties contained herein shall be made as
of the date hereof and as of each date from the date hereof through and
including the date that the Merger is consummated or this Agreement is
terminated in accordance with its terms.

            2.    Agreement to Vote Shares. Stockholder shall be present (in
person or by proxy) at and vote his Shares and any New Shares (as defined in
Section 4 hereof), and shall cause any holder of record of his Shares or New
Shares to be present and vote, (a) in favor of adoption and approval of the
Merger Agreement and the Merger (and each other action and transaction
contemplated by the Merger Agreement or by this Agreement) and (b) against any
Acquisition Proposal (as defined in the Merger Agreement) other than the Merger
(or any other Acquisition Proposal of Parent) and against any proposed action or
transaction that would prevent or intentionally delay consummation of the Merger
(or other Acquisition Proposal of Parent) or is otherwise inconsistent therewith
at every meeting of the stockholders of the Company at which any such matters
are considered and at every adjournment thereof (and, if applicable, in
connection with any request or solicitation of written consents of
stockholders). Any such vote shall be cast, or consent shall be given, in
accordance with such procedures relating thereto as shall ensure that it is duly
counted for purposes of determining that a quorum is present and for purposes of
recording the results of such vote or consent. Stockholder shall deliver to
Parent upon request a proxy substantially in the form attached hereto as Exhibit
B, which proxy shall be coupled with an interest and irrevocable to the extent
permitted under North Carolina law, with the total number of such Stockholder's
Shares and any New Shares correctly indicated thereon. Stockholder hereby
revokes any and all previous proxies granted with respect to his Shares.
Stockholder shall also use his reasonable best efforts to take, or cause to be
taken, all action, and do, or cause to be done, all things necessary or
advisable in order to consummate and make effective the transactions
contemplated by this Agreement.

            3.    No Voting Trusts. After the date hereof, Stockholder agrees
that he will not, nor will he permit any entity under his control to, deposit
any Shares in a voting trust or subject any Shares to any Lien or agreement,
arrangement or understanding with respect to the voting of such Shares other
than agreements entered into with Parent.

            4.    Additional Purchases. Stockholder agrees that in the event (a)
of any stock dividend, stock split, recapitalization, reclassification,
combination or exchange of shares of stock of the Company on, of or affecting
the Shares of such Stockholder, (b) such Stockholder purchases or otherwise
acquires beneficial ownership of any shares of Common Stock after the execution
of this Agreement (including by exercise of options), or (c) such Stockholder
acquires the right to vote or share in the voting of any shares of Common Stock
other than the Shares (collectively, "New Shares"), such Stockholder shall
deliver promptly to Parent upon request an irrevocable proxy substantially in
the form attached hereto as Exhibit B with respect to such New




                                      -2-


<PAGE>


Shares. Stockholder also agrees that any New Shares acquired or purchased by him
shall be subject to the terms of this Agreement and shall constitute Shares to
the same extent as if they were owned by such Stockholder on the date hereof.

            5.    Option Shares.

            (a)   Subject to the terms and conditions set forth herein,
Stockholder hereby grants to Parent an irrevocable option (the "Option") to
purchase, in whole or in part, such Stockholder's Shares and such Stockholder's
New Shares at a purchase price equal to the Per Share Cash Amount (as defined in
the Merger Agreement) per share; provided, however, that if the Per Share Cash
Amount under the Merger Agreement or any amendment thereto is ever increased or
if Parent shall otherwise offer to the Stockholders of the Company an increased
consideration for all of their shares (the "Greater Consideration"), then the
purchase price per share under the Option shall be increased to equal such new
Per Share Cash Amount or Greater Consideration; and provided further that if
Parent has exercised the Option within 12 months prior to such increase in the
Per Share Cash Amount or Greater Consideration, then Parent shall pay to each
Stockholder an amount equal to the product of the number of shares previously
purchased from such Stockholder pursuant to the Option and the amount of
increase between the old Per Share Cash Amount and the new Per Share Cash Amount
or Greater Consideration, as applicable.

            (b)   Parent may exercise the Option, in whole or in part, at any
time and from time to time, after the first to occur of (i) any event as a
result of which Parent shall be entitled to receive a termination fee pursuant
to Section 7.2(e) of the Merger Agreement in the amount of $52.5 million
pursuant to part (1) or part (2) of such Section or in the amount of $22.5
million pursuant to part (3) of such Section or (ii) the breach by any
Stockholder of Section 2 of this Agreement (the first of such events to occur, a
"Purchase Event"); provided, however, that except as provided in the last
sentence of this Section 5(b), the Option shall terminate and be of no further
force and effect upon the earliest to occur of (A) the Effective Time (as
defined in the Merger Agreement), (B) 12 months and one day after the occurrence
of a termination of the Merger Agreement in accordance with Section 7.1 (d),
(e), (f) or (g), (C) a termination of the Merger Agreement in accordance with
Section 7.1(a), (b), (c) or (h) of the Merger Agreement and (D) 18 months after
the Outside Date as defined in Section 7.1(e) of the Merger Agreement.
Notwithstanding the termination of the Option, Parent shall be entitled to
exercise the Option or receive the Cash Payment Amount if it has given written
notice of its intent to exercise the Option or receive the Cash Payment Amount
in accordance with the terms hereof prior to the termination of the Option and
the termination of the Option shall not affect any rights hereunder which by
their terms do not terminate or expire prior to or as of such termination.

            (c)   In the event that Parent wishes to exercise the Option, it
shall send to such Stockholder a written notice (the date of which being herein
referred to as the "Notice Date") to that effect which notice also specifies the
total number of shares Parent will purchase pursuant to such exercise, and a
date not earlier than three business days nor later than 15 business days from
the Notice Date for the closing of such purchase (the "Option Closing Date");
provided, however, that (i) if the closing of the purchase and sale pursuant to
the Option (the "Option




                                      -3-


<PAGE>


Closing") cannot be consummated by reason of any applicable judgment, decree,
order, law or regulation (including, without limitation, the rules and
regulations of the FCC), the period of time that otherwise would run pursuant to
this sentence shall run instead from the date on which such restriction on
consummation has expired or been terminated and (ii) without limiting the
foregoing, if prior notification to or approval of any Governmental Entity (as
defined in the Merger Agreement) is required in connection with such purchase or
any other transaction contemplated hereby, Parent and such Stockholder shall
promptly file the required notice or application for approval and shall
cooperate in the expeditious filing of such notice or application, and, in the
case of any prior notification or approval required in connection with such
purchase, the period of time that otherwise would run pursuant to this sentence
shall run instead from the date on which, as the case may be, (A) any required
notification period has expired or been terminated or (B) any required approval
has been obtained, and in either event, any requisite waiting period has expired
or been terminated. The place of the Option Closing shall be at the offices of
Wachtell, Lipton, Rosen & Katz, 51 West 52nd Street, New York, New York, and the
time of the Option Closing shall be 10:00 a.m. (Eastern Time) on the Option
Closing Date.

            (d)   At the Option Closing, Parent (or its designee) shall pay to
each Stockholder an amount equal to the product of (x) the Per Share Cash Amount
or Greater Consideration, as applicable, and (y) the number of shares being
purchased from such Stockholder pursuant to the exercise of the Option. Such
payment shall be in immediately available funds by wire transfer to a bank
account designated in writing by such Stockholder.

            (e)   At the Option Closing, simultaneously with the delivery of the
amount specified in Section 5(d), each Stockholder shall deliver to Parent (or
its designee) a certificate or certificates representing its shares to be
purchased at the Option Closing, which shares shall be free and clear of all
Liens, claims, charges and encumbrances of any kind whatsoever, except for such
encumbrances or proxies in favor of Parent arising hereunder, and a new Option
evidencing the rights of the Parent (or its designee) to purchase the balance of
such Stockholder's shares purchasable hereunder.

            6.    Cash Election.

            (a)   In lieu of exercising the Option, by notice, Parent may
require such Stockholder to make a cash payment to Parent in the amount (the
"Cash Payment Amount") equal to the amount by which (A) the Market Price (as
defined below) exceeds (B) the Per Share Cash Amount, multiplied by the sum of
(i) the number of such Stockholder's Shares and (ii) the number of such
Stockholder's New Shares. Upon receipt of such notice, the Stockholder shall be
permitted to sell a sufficient number of Shares to pay the Cash Payment Amount,
if Stockholder shall, within five business days of such notice, sell such
Shares, provided that Stockholder shall use reasonable best efforts to achieve
good execution and shall consult with Parent with respect to the manner of
disposition. The term "Market Price" shall mean the closing price (as measured
by the last completed trade) for shares of Common Stock on the date of Parent's
election, or if Stockholder elects to sell Shares to pay the Cash Payment Amount
and has complied with the




                                      -4-


<PAGE>


proviso to the immediately preceding sentence, the average price per Share
actually realized in such sale.

            (b)   Parent may exercise its right to require such Stockholder to
pay the Cash Payment Amount pursuant to this Section by surrendering for such
purpose to such Stockholder, at the Company's principal office, a copy of this
Agreement, accompanied by a written notice or notices stating that Parent elects
to require such Stockholder to pay the Cash Payment Amount in accordance with
the provisions of this Section. Within five (or, in the case of a sale of Shares
under (a) above to fund the Cash Payment Amount, eight) business days after the
surrender of the Option and the receipt of such notice or notices relating
thereto, such Stockholder shall deliver or cause to be delivered to Parent the
Cash Payment Amount by wire to the account designated by Parent in immediately
available funds.

            (c)   If Stockholder at any time after delivery of a notice of
election by Parent to take the Cash Payment Amount pursuant to this Section is
prohibited under applicable law or regulation from selling Shares in order to
deliver to Parent the Cash Payment Amount in full, and Stockholder is required
to sell Shares to fund the Cash Payment Amount, then (i) such Stockholder hereby
undertakes to use such Stockholder's reasonable best efforts, to the extent
within the control of such Stockholder, to obtain all required regulatory and
legal approvals and to file any required notices, in each case as promptly as
practicable in order to accomplish such sales and (ii) if Stockholder is unable
to effect sales within four days after the receipt of notice, such Stockholder
shall be permitted to pay the Cash Payment Amount to Parent in Shares valued at
the Market Price.

            7.    No Encumbrances.

            (a)   Except as expressly contemplated by this Agreement,
Stockholder's Shares and the certificates representing such Shares are now, and
at all times during the term hereof will be, held by such Stockholder, or by a
nominee or custodian for the benefit of such Stockholder, free and clear of all
liens, claims, security interests, proxies, voting trusts or agreements,
understandings or arrangements or any other encumbrances whatsoever (other than
to the extent set forth on Schedule 1 to this Agreement), except for any such
encumbrances or proxies arising hereunder.

            (b)   Notwithstanding the foregoing, any Stockholder which has
received a notice of election by Parent (or its designee) to receive the Cash
Payment Amount shall be permitted, between receipt of such notice and the time
on which the Cash Payment Amount is due to be paid, to sell such number of
Shares as may be necessary to satisfy such obligation, as described in Section
6(a) above.

            (c)   Any transfer by Stockholder of its Shares to Parent pursuant
to the Option shall pass to and unconditionally vest in Parent good and valid
title to such Stockholder's Shares and New Shares, free and clear of all claims,
liens, restrictions, security interests, pledges, limitations and encumbrances
whatsoever.

            8.    Acquisition Proposals. Stockholder agrees that such Stock-
holder (i) shall not, directly or indirectly, initiate, solicit, encourage or
otherwise facilitate any inquiries or the making of any Acquisition Proposal and
(ii) has terminated any discussions or negotiations with, and the provision of
information or data to, any Person (other than Parent) respecting an Acquisition
Proposal. Such Stockholder further agrees that he shall not, directly or
indirectly, provide any confidential information or data to any Person (as
defined in the Merger Agreement) relating to or in contemplation of an
Acquisition Proposal or engage in any negotiations or discussions relating to or
in contemplation of an Acquisition Proposal. Such Stockholder will notify Parent
immediately if any inquiries, proposals or offers respecting an Acquisition
Proposal are received by, any such information or data is requested from, or any
such discussions or negotiations are sought to be initiated or continued with,
such Stockholder indicating, in connection with such notice, the name of such
Person and the material terms and conditions of any proposals or offers, and
shall keep Parent apprised with respect to the status and terms thereof.

            9.    Appraisal Rights. Stockholder agrees not to exercise any
rights (including, without limitation, under Article 13 of the North Carolina
Business Corporation Act) to demand appraisal of any Common Stock which may
arise with respect to the Merger.

            10.   Affiliates Letter. Stockholder shall execute and deliver on a

execution and delivery of this Agreement.

            12.   Specific Performance. Each party hereto severally acknowledges
that it will be impossible to measure in money the damage to the other parties
if the party hereto fails to comply with any of the obligations imposed by this
Agreement, that every such obligation is material and that, in the event of any
such failure, the other parties will not have an adequate remedy at law or
damages. Accordingly, each party hereto severally agrees that injunctive relief
or other equitable remedy, in addition to remedies at law or damages, is the
appropriate remedy for any such failure and will not oppose the granting of such
relief on the basis that any other party has an adequate remedy at law. Each
party hereto severally agrees that it will not seek, and agrees to waive any
requirement for, the securing or posting of a bond in connection with any other
party's seeking or obtaining such equitable relief.

            13.   Heirs, Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective heirs,
successors and assigns and shall not be assignable without the written consent
of all other parties hereto other than any assignment in whole or in part by
Parent.

            14.   Entire Agreement. This Agreement supersedes all prior
agreements, written or oral, among the parties hereto with respect to the
subject matter hereof and contains the entire agreement among the parties with
respect to the subject matter hereof. This Agreement may not be amended,
supplemented or modified, and no provisions hereof may be modified or




                                      -6-


<PAGE>


waived, except by an instrument in writing signed by all the parties hereto. No
waiver of any provisions hereof by any party shall be deemed a waiver of any
other provisions hereof by any such party, nor shall any such waiver be deemed a
continuing waiver of any provision hereof by such party.

            15.   Miscellaneous.

            (a)   Expenses. Each of the parties hereto shall bear and pay all
costs and expenses incurred by it or on its behalf in connection with the
negotiation of this Agreement, including fees and expenses of its own financial
consultants, investment bankers, accountants and counsel.

            (b)   Amendment. This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

            (c)   This Agreement shall be deemed a contract made under, and for
all purposes shall be construed in accordance with, the internal laws of the
State of New York without regard to principles of conflicts of law, except for
those provisions relating to the voting and the proxy which shall be governed by
North Carolina law.

            (d)   Severability. If any provision of this Agreement or the
application of such provision to any person or circumstances shall be held
invalid by a court of competent jurisdiction, the remainder of the provision
held invalid and the application of such provision to persons or circumstances,
other than the party as to which it is held invalid, shall not be affected.

            (e)   Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together shall constitute one and the same instrument.

            (f)   Termination. This Agreement shall terminate upon termination
of the Option.

            (g)   Headings. All Section headings herein are for convenience of

                                  FORM OF PROXY


            The undersigned stockholder, for consideration received, hereby

substitution in each of them, to cast on behalf of the undersigned all votes
entitled to be cast by the holder of the shares of Class A Common Stock, par

adjournment thereof (i) "FOR" approval and adoption of the Agreement and Plan of
Merger, dated as of October 2, 1998, between the Company and AT&T Corp., a New
York corporation ("Parent"), providing for the merger (the "Merger") of the
Company with and into a wholly-owned subsidiary of Parent, and the Merger and

liquidation, dissolution or similar transaction involving, or any purchase of
any substantial portion of the assets of, or any equity securities of, or any

inconsistent therewith. This proxy is coupled with an interest and is
irrevocable until such time as the Voting Agreement, dated as of December 22,

                               VOTING AGREEMENT


            VOTING AGREEMENT (the "Agreement"), dated as of December 22,
1998, between the undersigned stockholder ("Stockholder") of Vanguard
Cellular Systems, Inc., a North Carolina corporation (the "Company"), and
AT&T Corp., a New York corporation ("Parent").

            WHEREAS, prior to the execution and delivery of this Agreement,
the Company and Parent have entered into an Agreement and Plan of Merger
dated as of October 2, 1998 (the "Merger Agreement"), providing for the
merger of the Company with and into a wholly-owned subsidiary of Parent (the
"Merger") pursuant to the terms and conditions thereof; and

            WHEREAS, as an inducement and a condition to Parent entering into
the Merger Agreement, various stockholders of the Company signed voting
agreements with Parent, which agreements restrict the transfer of the Class A
Common Stock, par value $0.01 per share, of the Company (the "Common Stock")
owned by such stockholders; and

            WHEREAS, in accordance with such restrictions it is necessary for
Stockholder to sign this Agreement to receive certain shares of the Common
Stock;

            NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

            1.    Representations of Stockholder.  Stockholder represents
that:

            (a)   such Stockholder is or may become the beneficial owner of
the number of shares of Common Stock set forth opposite such Stockholder's
name on Exhibit A (such Stockholder's "Shares");

            (b)   except as may be denoted in Exhibit A, as of the date
hereof such Stockholder does not beneficially own (as such term is defined in
the Securities Exchange Act of 1934, as amended (the "1934 Act")) or own of
record any shares of Common Stock other than such Stockholder's Shares, but
excluding any shares of Common Stock which such Stockholder has the right to
obtain upon the exercise of stock options outstanding on the date hereof;

            (c)   such Stockholder has the right, power and authority to
execute and deliver this Agreement and to perform such Stockholder's
obligations under this Agreement, and this Agreement has been duly executed
and delivered by such Stockholder and constitutes a valid and legally binding
agreement of such Stockholder, enforceable in accordance with its terms; and
such execution, delivery and performance by such Stockholder of this
Agreement will not (i) conflict with, require a consent, waiver or approval
under, or result in a breach of or default under, any of the terms of any
contract, commitment or other obligation (written or oral) to which such
Stockholder is a party or by which such Stockholder is bound; (ii) violate
any order, writ, injunction, decree or statute, or any rule or regulation,
applicable to Stockholder or any of the properties or assets of Stockholder;
or (iii) result in the creation of, or impose any obligation 

<PAGE>

on such Stockholder to create, any Lien (as defined in the Merger Agreement),
charge or other encumbrance of any nature whatsoever upon the Shares, other than
in favor of Parent; and

            (d)   L. Richardson Preyer, Jr. and The Preyer-Jacobs Foundation are
the sole beneficiaries of the Lunsford Richardson Preyer, Jr. Charitable
Remainder Unitrust.

            The representations and warranties contained herein shall be made
as of the date hereof and as of each date from the date hereof through and
including the date that the Merger is consummated or this Agreement is
terminated in accordance with its terms.

            2.    Agreement to Vote Shares.  Stockholder shall be present (in
person or by proxy) at and vote his Shares and any New Shares (as defined in
Section 4 hereof), and shall cause any holder of record of his Shares or New
Shares to be present and vote, (a) in favor of adoption and approval of the
Merger Agreement and the Merger (and each other action and transaction
contemplated by the Merger Agreement or by this Agreement) and (b) against
any Acquisition Proposal (as defined in the Merger Agreement) other than the
Merger (or any other Acquisition Proposal of Parent) and against any proposed
action or transaction that would prevent or intentionally delay consummation
of the Merger (or other Acquisition Proposal of Parent) or is otherwise
inconsistent therewith at every meeting of the stockholders of the Company at
which any such matters are considered and at every adjournment thereof (and,
if applicable, in connection with any request or solicitation of written
consents of stockholders).  Any such vote shall be cast, or consent shall be
given, in accordance with such procedures relating thereto as shall ensure
that it is duly counted for purposes of determining that a quorum is present
and for purposes of recording the results of such vote or consent.
Stockholder shall deliver to Parent upon request a proxy substantially in the
form attached hereto as Exhibit B, which proxy shall be coupled with an
interest and irrevocable to the extent permitted under North Carolina law,
with the total number of such Stockholder's Shares and any New Shares
correctly indicated thereon.  Stockholder hereby revokes any and all previous
proxies granted with respect to his Shares.  Stockholder shall also use his
reasonable best efforts to take, or cause to be taken, all action, and do, or
cause to be done, all things necessary or advisable in order to consummate
and make effective the transactions contemplated by this Agreement.

            3.    No Voting Trusts.  After the date hereof, Stockholder
agrees that he will not, nor will he permit any entity under his control to,
deposit any Shares in a voting trust or subject any Shares to any Lien or
agreement, arrangement or understanding with respect to the voting of such
Shares other than agreements entered into with Parent.

            4.    Additional Purchases.  Stockholder agrees that in the event
(a) of any stock dividend, stock split, recapitalization, reclassification,
combination or exchange of shares of stock of the Company on, of or affecting
the Shares of such Stockholder, (b) such Stockholder purchases or otherwise
acquires beneficial ownership of any shares of Common Stock after the
execution of this Agreement (including by exercise of options), or (c) such
Stockholder acquires the right to vote or share in the voting of any shares
of Common Stock other than the Shares

                                      -2-
<PAGE>

(collectively, "New Shares"), such Stockholder shall deliver promptly to Parent
upon request an irrevocable proxy substantially in the form attached hereto as
Exhibit B with respect to such New Shares. Stockholder also agrees that any New
Shares acquired or purchased by him shall be subject to the terms of this
Agreement and shall constitute Shares to the same extent as if they were owned
by such Stockholder on the date hereof.

            5.    Option Shares.

            (a)   Subject to the terms and conditions set forth herein,
Stockholder hereby grants to Parent an irrevocable option (the "Option") to
purchase, in whole or in part, such Stockholder's Shares and such
Stockholder's New Shares at a purchase price equal to the Per Share Cash
Amount (as defined in the Merger Agreement) per share; provided, however,
that if the Per Share Cash Amount under the Merger Agreement or any amendment
thereto is ever increased or if Parent shall otherwise offer to the
Stockholders of the Company an increased consideration for all of their
shares (the "Greater Consideration"), then the purchase price per share under
the Option shall be increased to equal such new Per Share Cash Amount or
Greater Consideration; and provided further that if Parent has exercised the
Option within 12 months prior to such increase in the Per Share Cash Amount
or Greater Consideration, then Parent shall pay to each Stockholder an amount
equal to the product of the number of shares previously purchased from such
Stockholder pursuant to the Option and the amount of increase between the old
Per Share Cash Amount and the new Per Share Cash Amount or Greater
Consideration, as applicable.

            (b)   Parent may exercise the Option, in whole or in part, at any
time and from time to time, after the first to occur of (i) any event as a
result of which Parent shall be entitled to receive a termination fee
pursuant to Section 7.2(e) of the Merger Agreement in the amount of $52.5
million pursuant to part (1) or part (2) of such Section or in the amount of
$22.5 million pursuant to part (3) of such Section or (ii) the breach by any
Stockholder of Section 2 of this Agreement (the first of such events to
occur, a "Purchase Event"); provided, however, that except as provided in the
last sentence of this Section 5(b), the Option shall terminate and be of no
further force and effect upon the earliest to occur of (A) the Effective Time
(as defined in the Merger Agreement), (B) 12 months and one day after the
occurrence of a termination of the Merger Agreement in accordance with
Section 7.1 (d), (e), (f) or (g), (C) a termination of the Merger Agreement
in accordance with Section 7.1(a), (b), (c) or (h) of the Merger Agreement
and (D) 18 months after the Outside Date as defined in Section 7.1(e) of the
Merger Agreement.  Notwithstanding the termination of the Option, Parent
shall be entitled to exercise the Option or receive the Cash Payment Amount
if it has given written notice of its intent to exercise the Option or
receive the Cash Payment Amount in accordance with the terms hereof prior to
the termination of the Option and the termination of the Option shall not
affect any rights hereunder which by their terms do not terminate or expire
prior to or as of such termination.

            (c)   In the event that Parent wishes to exercise the Option, it
shall send to such Stockholder a written notice (the date of which being
herein referred to as the "Notice Date") to that effect which notice also
specifies the total number of shares Parent will purchase pursuant to such

the Notice Date for the closing of such purchase (the "Option Closing Date");
provided, however, that (i) if the closing of the purchase and sale pursuant to
the Option (the "Option Closing") cannot be consummated by reason of any
applicable judgment, decree, order, law or regulation (including, without
limitation, the rules and regulations of the FCC), the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which such restriction on consummation has expired or been terminated and (ii)
without limiting the foregoing, if prior notification to or approval of any
Governmental Entity (as defined in the Merger Agreement) is required in
connection with such purchase or any other transaction contemplated hereby,
Parent and such Stockholder shall promptly file the required notice or
application for approval and shall cooperate in the expeditious filing of such
notice or application, and, in the case of any prior notification or approval
required in connection with such purchase, the period of time that otherwise
would run pursuant to this sentence shall run instead from the date on which, as
the case may be, (A) any required notification period has expired or been
terminated or (B) any required approval has been obtained, and in either event,
any requisite waiting period has expired or been terminated. The place of the
Option Closing shall be at the offices of Wachtell, Lipton, Rosen & Katz, 51
West 52nd Street, New York, New York, and the time of the Option Closing shall
be 10:00 a.m. (Eastern Time) on the Option Closing Date.

            (d)   At the Option Closing, Parent (or its designee) shall pay
to each Stockholder an amount equal to the product of (x) the Per Share Cash
Amount or Greater Consideration, as applicable, and (y) the number of shares
being purchased from such Stockholder pursuant to the exercise of the
Option.  Such payment shall be in immediately available funds by wire
transfer to a bank account designated in writing by such Stockholder.

            (e)   At the Option Closing, simultaneously with the delivery of
the amount specified in Section 5(d), each Stockholder shall deliver to
Parent (or its designee) a certificate or certificates representing its
shares to be purchased at the Option Closing, which shares shall be free and
clear of all Liens, claims, charges and encumbrances of any kind whatsoever,
except for such encumbrances or proxies in favor of Parent arising hereunder,
and a new Option evidencing the rights of the Parent (or its designee) to
purchase the balance of such Stockholder's shares purchasable hereunder.

            6.    Cash Election.

            (a)   In lieu of exercising the Option, by notice, Parent may
require such Stockholder to make a cash payment to Parent in the amount (the
"Cash Payment Amount") equal to the amount by which (A) the Market Price (as
defined below) exceeds (B) the Per Share Cash Amount, multiplied by the sum
of (i) the number of such Stockholder's Shares and (ii) the number of such
Stockholder's New Shares.  Upon receipt of such notice, the Stockholder shall
be permitted to sell a sufficient number of Shares to pay the Cash Payment
Amount, if Stockholder shall, within five business days of such notice, sell
such Shares, provided that Stockholder shall use reasonable best efforts to
achieve good execution and shall consult with Parent with respect to the
manner of disposition.  The term "Market Price" shall mean the closing price
(as measured by the last completed trade) for shares of Common Stock on the
date of Parent's election, or if 

                                      -4-


<PAGE>

Stockholder elects to sell Shares to pay the Cash Payment Amount and has
complied with the proviso to the immediately preceding sentence, the average
price per Share actually realized in such sale.

            (b)   Parent may exercise its right to require such Stockholder to 
pay the Cash Payment Amount pursuant to this Section by surrendering for such
purpose to such Stockholder, at the Company's principal office, a copy of this
Agreement, accompanied by a written notice or notices stating that Parent elects
to require such Stockholder to pay the Cash Payment Amount in accordance with
the provisions of this Section. Within five (or, in the case of a sale of Shares
under (a) above to fund the Cash Payment Amount, eight) business days after the
surrender of the Option and the receipt of such notice or notices relating
thereto, such Stockholder shall deliver or cause to be delivered to Parent the
Cash Payment Amount by wire to the account designated by Parent in immediately
available funds.

            (c)   If Stockholder at any time after delivery of a notice of
election by Parent to take the Cash Payment Amount pursuant to this Section is
prohibited under applicable law or regulation from selling Shares in order to
deliver to Parent the Cash Payment Amount in full, and Stockholder is required
to sell Shares to fund the Cash Payment Amount, then (i) such Stockholder hereby
undertakes to use such Stockholder's reasonable best efforts, to the extent
within the control of such Stockholder, to obtain all required regulatory and
legal approvals and to file any required notices, in each case as promptly as
practicable in order to accomplish such sales and (ii) if Stockholder is unable
to effect sales within four days after the receipt of notice, such Stockholder
shall be permitted to pay the Cash Payment Amount to Parent in Shares valued at
the Market Price.

            7.    No Encumbrances.

            (a)   Except as expressly contemplated by this Agreement,
Stockholder's Shares and the certificates representing such Shares are now,
and at all times during the term hereof will be, held by such Stockholder, or
by a nominee or custodian for the benefit of such Stockholder, free and clear
of all liens, claims, security interests, proxies, voting trusts or
agreements, understandings or arrangements or any other encumbrances
whatsoever (other than to the extent set forth on Schedule 1 to this
Agreement), except for any such encumbrances or proxies arising hereunder.

            (b)   Notwithstanding the foregoing, any Stockholder which has
received a notice of election by Parent (or its designee) to receive the Cash
Payment Amount shall be permitted, between receipt of such notice and the
time on which the Cash Payment Amount is due to be paid, to sell such number
of Shares as may be necessary to satisfy such obligation, as described in
Section 6(a) above.

            (c)   Any transfer by Stockholder of its Shares to Parent
pursuant to the Option shall pass to and unconditionally vest in Parent good
and valid title to such Stockholder's Shares and New Shares, free and clear
of all claims, liens, restrictions, security interests, pledges, limitations
and encumbrances whatsoever.

                                      -5-

<PAGE>

            8.    Acquisition Proposals.  Stockholder agrees that such
Stockholder (i) shall not, directly or indirectly, initiate, solicit, encourage
or otherwise facilitate any inquiries or the making of any Acquisition Proposal
and (ii) has terminated any discussions or negotiations with, and the provision
of information or data to, any Person (other than Parent) respecting an
Acquisition Proposal. Such Stockholder further agrees that he shall not,
directly or indirectly, provide any confidential information or data to any
Person (as defined in the Merger Agreement) relating to or in contemplation of
an Acquisition Proposal or engage in any negotiations or discussions relating to
or in contemplation of an Acquisition Proposal. Such Stockholder will notify
Parent immediately if any inquiries, proposals or offers respecting an
Acquisition Proposal are received by, any such information or data is requested
from, or any such discussions or negotiations are sought to be initiated or
continued with, such Stockholder indicating, in connection with such notice, the
name of such Person and the material terms and conditions of any proposals or
offers, and shall keep Parent apprised with respect to the status and terms
thereof.

            9.    Appraisal Rights.  Stockholder agrees not to exercise any
rights (including, without limitation, under Article 13 of the North Carolina
Business Corporation Act) to demand appraisal of any Common Stock which may
arise with respect to the Merger.

            10.   Affiliates Letter.  Stockholder shall execute and deliver
on a timely basis an Affiliate Letter (as defined in the Merger Agreement).

            11.   Reliance by Parent.  Stockholder understands and
acknowledges that Parent is entering into the Merger Agreement in reliance
upon Stockholder's execution and delivery of this Agreement.

            12.   Specific Performance.  Each party hereto severally
acknowledges that it will be impossible to measure in money the damage to the
other parties if the party hereto fails to comply with any of the obligations
imposed by this Agreement, that every such obligation is material and that,
in the event of any such failure, the other parties will not have an adequate
remedy at law or damages.  Accordingly, each party hereto severally agrees
that injunctive relief or other equitable remedy, in addition to remedies at
law or damages, is the appropriate remedy for any such failure and will not
oppose the granting of such relief on the basis that any other party has an
adequate remedy at law.  Each party hereto severally agrees that it will not
seek, and agrees to waive any requirement for, the securing or posting of a
bond in connection with any other party's seeking or obtaining such equitable
relief.

            13.   Heirs, Successors and Assigns.  This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their
respective heirs, successors and assigns and shall not be assignable without
the written consent of all other parties hereto other than any assignment in
whole or in part by Parent.

            14.   Entire Agreement.  This Agreement supersedes all prior
agreements, written or oral, among the parties hereto with respect to the
subject matter hereof and contains the entire agreement among the parties
with respect to the subject matter hereof.  This Agreement may not be
amended, supplemented or modified, and no provisions hereof may be modified
or 

                                      -6-


<PAGE>

waived, except by an instrument in writing signed by all the parties
hereto.  No waiver of any provisions hereof by any party shall be deemed a
waiver of any other provisions hereof by any such party, nor shall any such
waiver be deemed a continuing waiver of any provision hereof by such party.

            15.   Miscellaneous.

            (a)   Expenses.  Each of the parties hereto shall bear and pay
all costs and expenses incurred by it or on its behalf in connection with the
negotiation of this Agreement, including fees and expenses of its own
financial consultants, investment bankers, accountants and counsel.

            (b)   Amendment.  This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

            (c)   This Agreement shall be deemed a contract made under, and
for all purposes shall be construed in accordance with, the internal laws of
the State of New York without regard to principles of conflicts of law,
except for those provisions relating to the voting and the proxy which shall
be governed by North Carolina law.

            (d)   Severability.  If any provision of this Agreement or the
application of such provision to any person or circumstances shall be held
invalid by a court of competent jurisdiction, the remainder of the provision
held invalid and the application of such provision to persons or
circumstances, other than the party as to which it is held invalid, shall not
be affected.

            (e)   Counterparts.  This Agreement may be executed in one or
more counterparts, each of which shall be deemed to be an original but all of
which together shall constitute one and the same instrument.

            (f)   Termination.  This Agreement shall terminate upon
termination of the Option.

            (g)   Headings.  All Section headings herein are for convenience
of reference only and are not part of this Agreement and no construction or
reference shall be derived therefrom.

            (h)   Notices.  All notices, requests, claims, demands, and other
communications under this Agreement must be in writing and shall be deemed

                               FORM OF PROXY


            The undersigned stockholder, for consideration received, hereby
appoints [PARENT DESIGNEES] and each of them as my proxies, with full power
of substitution in each of them, to cast on behalf of the undersigned all
votes entitled to be cast by the holder of the shares of Class A Common
Stock, par value $0.01 per share, of Vanguard Cellular Systems, Inc., a North
Carolina corporation (the "Company"), owned by the undersigned at the Special
Meeting of Stockholders of the Company to be held [DATE, TIME AND PLACE] and
at any adjournment thereof (i) "FOR" approval and adoption of the Agreement
and Plan of Merger, dated as of October 2, 1998, between the Company and AT&T
Corp., a New York corporation ("Parent"), providing for the merger (the
"Merger") of the Company with and into a wholly-owned subsidiary of Parent,
and the Merger and (ii) "AGAINST" any proposal or offer with respect to a
merger, reorganization, share exchange, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving,
or any purchase of any substantial portion of the assets of, or any equity
securities of, or any transaction that would involve the transfer or
potential transfer of control of, the Company other than the Merger and any
proposed action or transaction that would prevent or intentionally delay
consummation of the Merger or is otherwise inconsistent therewith.  This

                               VOTING AGREEMENT


            VOTING AGREEMENT (the "Agreement"), dated as of December 22,
1998, between the undersigned stockholder ("Stockholder") of Vanguard
Cellular Systems, Inc., a North Carolina corporation (the "Company"), and
AT&T Corp., a New York corporation ("Parent").

            WHEREAS, prior to the execution and delivery of this Agreement,
the Company and Parent have entered into an Agreement and Plan of Merger
dated as of October 2, 1998 (the "Merger Agreement"), providing for the
merger of the Company with and into a wholly-owned subsidiary of Parent (the
"Merger") pursuant to the terms and conditions thereof; and

            WHEREAS, as an inducement and a condition to Parent entering into
the Merger Agreement, various stockholders of the Company signed voting
agreements with Parent, which agreements restrict the transfer of the Class A
Common Stock, par value $0.01 per share, of the Company (the "Common Stock")
owned by such stockholders; and

            WHEREAS, in accordance with such restrictions it is necessary for
Stockholder to sign this Agreement to receive certain shares of the Common
Stock;

            NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

            1.    Representations of Stockholder.  Stockholder represents
that:

            (a)   such Stockholder is or may become the beneficial owner of
the number of shares of Common Stock set forth opposite such Stockholder's
name on Exhibit A (such Stockholder's "Shares");

            (b)   except as may be denoted in Exhibit A, as of the date
hereof such Stockholder does not beneficially own (as such term is defined in
the Securities Exchange Act of 1934, as amended (the "1934 Act")) or own of
record any shares of Common Stock other than such Stockholder's Shares, but
excluding any shares of Common Stock which such Stockholder has the right to
obtain upon the exercise of stock options outstanding on the date hereof;

            (c)   such Stockholder has the right, power and authority to
execute and deliver this Agreement and to perform such Stockholder's
obligations under this Agreement, and this Agreement has been duly executed
and delivered by such Stockholder and constitutes a valid and legally binding
agreement of such Stockholder, enforceable in accordance with its terms; and
such execution, delivery and performance by such Stockholder of this
Agreement will not (i) conflict with, require a consent, waiver or approval
under, or result in a breach of or default under, any of the terms of any
contract, commitment or other obligation (written or oral) to which such
Stockholder is a party or by which such Stockholder is bound; (ii) violate
any order, writ, injunction, decree or statute, or any rule or regulation,
applicable to Stockholder or any of the properties or assets of Stockholder;
or (iii) result in the creation of, or impose any obligation 

<PAGE>

on such Stockholder to create, any Lien (as defined in the Merger Agreement),
charge or other encumbrance of any nature whatsoever upon the Shares, other than
in favor of Parent; and

            (d)    Stephen R. Leeolou and Mary D. Leeolou are the sole
beneficiaries of The Stephen R. and Mary D. Leeolou 1998 Charitable Remainder
Unitrust.

            The representations and warranties contained herein shall be made
as of the date hereof and as of each date from the date hereof through and
including the date that the Merger is consummated or this Agreement is
terminated in accordance with its terms.

            2.    Agreement to Vote Shares.  Stockholder shall be present (in
person or by proxy) at and vote his Shares and any New Shares (as defined in
Section 4 hereof), and shall cause any holder of record of his Shares or New
Shares to be present and vote, (a) in favor of adoption and approval of the
Merger Agreement and the Merger (and each other action and transaction
contemplated by the Merger Agreement or by this Agreement) and (b) against
any Acquisition Proposal (as defined in the Merger Agreement) other than the
Merger (or any other Acquisition Proposal of Parent) and against any proposed
action or transaction that would prevent or intentionally delay consummation
of the Merger (or other Acquisition Proposal of Parent) or is otherwise
inconsistent therewith at every meeting of the stockholders of the Company at
which any such matters are considered and at every adjournment thereof (and,
if applicable, in connection with any request or solicitation of written
consents of stockholders).  Any such vote shall be cast, or consent shall be
given, in accordance with such procedures relating thereto as shall ensure
that it is duly counted for purposes of determining that a quorum is present
and for purposes of recording the results of such vote or consent.
Stockholder shall deliver to Parent upon request a proxy substantially in the
form attached hereto as Exhibit B, which proxy shall be coupled with an
interest and irrevocable to the extent permitted under North Carolina law,
with the total number of such Stockholder's Shares and any New Shares
correctly indicated thereon.  Stockholder hereby revokes any and all previous
proxies granted with respect to his Shares.  Stockholder shall also use his
reasonable best efforts to take, or cause to be taken, all action, and do, or
cause to be done, all things necessary or advisable in order to consummate
and make effective the transactions contemplated by this Agreement.

            3.    No Voting Trusts.  After the date hereof, Stockholder
agrees that he will not, nor will he permit any entity under his control to,
deposit any Shares in a voting trust or subject any Shares to any Lien or
agreement, arrangement or understanding with respect to the voting of such
Shares other than agreements entered into with Parent.

            4.    Additional Purchases.  Stockholder agrees that in the event
(a) of any stock dividend, stock split, recapitalization, reclassification,
combination or exchange of shares of stock of the Company on, of or affecting
the Shares of such Stockholder, (b) such Stockholder purchases or otherwise
acquires beneficial ownership of any shares of Common Stock after the
execution of this Agreement (including by exercise of options), or (c) such
Stockholder acquires the right to vote or share in the voting of any shares
of Common Stock other than the Shares

                                      -2-


<PAGE>

(collectively, "New Shares"), such Stockholder shall deliver promptly to Parent
upon request an irrevocable proxy substantially in the form attached hereto as
Exhibit B with respect to such New Shares. Stockholder also agrees that any New
Shares acquired or purchased by him shall be subject to the terms of this
Agreement and shall constitute Shares to the same extent as if they were owned
by such Stockholder on the date hereof.

            5.    Option Shares.

            (a)   Subject to the terms and conditions set forth herein,
Stockholder hereby grants to Parent an irrevocable option (the "Option") to
purchase, in whole or in part, such Stockholder's Shares and such
Stockholder's New Shares at a purchase price equal to the Per Share Cash
Amount (as defined in the Merger Agreement) per share; provided, however,
that if the Per Share Cash Amount under the Merger Agreement or any amendment
thereto is ever increased or if Parent shall otherwise offer to the
Stockholders of the Company an increased consideration for all of their
shares (the "Greater Consideration"), then the purchase price per share under
the Option shall be increased to equal such new Per Share Cash Amount or
Greater Consideration; and provided further that if Parent has exercised the
Option within 12 months prior to such increase in the Per Share Cash Amount
or Greater Consideration, then Parent shall pay to each Stockholder an amount
equal to the product of the number of shares previously purchased from such
Stockholder pursuant to the Option and the amount of increase between the old
Per Share Cash Amount and the new Per Share Cash Amount or Greater
Consideration, as applicable.

            (b)   Parent may exercise the Option, in whole or in part, at any
time and from time to time, after the first to occur of (i) any event as a
result of which Parent shall be entitled to receive a termination fee
pursuant to Section 7.2(e) of the Merger Agreement in the amount of $52.5
million pursuant to part (1) or part (2) of such Section or in the amount of
$22.5 million pursuant to part (3) of such Section or (ii) the breach by any
Stockholder of Section 2 of this Agreement (the first of such events to
occur, a "Purchase Event"); provided, however, that except as provided in the
last sentence of this Section 5(b), the Option shall terminate and be of no
further force and effect upon the earliest to occur of (A) the Effective Time
(as defined in the Merger Agreement), (B) 12 months and one day after the
occurrence of a termination of the Merger Agreement in accordance with
Section 7.1 (d), (e), (f) or (g), (C) a termination of the Merger Agreement
in accordance with Section 7.1(a), (b), (c) or (h) of the Merger Agreement
and (D) 18 months after the Outside Date as defined in Section 7.1(e) of the
Merger Agreement.  Notwithstanding the termination of the Option, Parent
shall be entitled to exercise the Option or receive the Cash Payment Amount
if it has given written notice of its intent to exercise the Option or
receive the Cash Payment Amount in accordance with the terms hereof prior to
the termination of the Option and the termination of the Option shall not
affect any rights hereunder which by their terms do not terminate or expire
prior to or as of such termination.

            (c)   In the event that Parent wishes to exercise the Option, it
shall send to such Stockholder a written notice (the date of which being
herein referred to as the "Notice Date") to that effect which notice also
specifies the total number of shares Parent will purchase pursuant to such
exercise, and a date not earlier than three business days nor later than 15
business days from

                                      -3-


<PAGE>

the Notice Date for the closing of such purchase (the "Option Closing Date");
provided, however, that (i) if the closing of the purchase and sale pursuant to
the Option (the "Option Closing") cannot be consummated by reason of any
applicable judgment, decree, order, law or regulation (including, without
limitation, the rules and regulations of the FCC), the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which such restriction on consummation has expired or been terminated and (ii)
without limiting the foregoing, if prior notification to or approval of any
Governmental Entity (as defined in the Merger Agreement) is required in
connection with such purchase or any other transaction contemplated hereby,
Parent and such Stockholder shall promptly file the required notice or
application for approval and shall cooperate in the expeditious filing of such
notice or application, and, in the case of any prior notification or approval
required in connection with such purchase, the period of time that otherwise
would run pursuant to this sentence shall run instead from the date on which, as
the case may be, (A) any required notification period has expired or been
terminated or (B) any required approval has been obtained, and in either event,
any requisite waiting period has expired or been terminated. The place of the
Option Closing shall be at the offices of Wachtell, Lipton, Rosen & Katz, 51
West 52nd Street, New York, New York, and the time of the Option Closing shall
be 10:00 a.m. (Eastern Time) on the Option Closing Date.

            (d)   At the Option Closing, Parent (or its designee) shall pay
to each Stockholder an amount equal to the product of (x) the Per Share Cash
Amount or Greater Consideration, as applicable, and (y) the number of shares
being purchased from such Stockholder pursuant to the exercise of the
Option.  Such payment shall be in immediately available funds by wire
transfer to a bank account designated in writing by such Stockholder.

            (e)   At the Option Closing, simultaneously with the delivery of
the amount specified in Section 5(d), each Stockholder shall deliver to
Parent (or its designee) a certificate or certificates representing its
shares to be purchased at the Option Closing, which shares shall be free and
clear of all Liens, claims, charges and encumbrances of any kind whatsoever,
except for such encumbrances or proxies in favor of Parent arising hereunder,
and a new Option evidencing the rights of the Parent (or its designee) to
purchase the balance of such Stockholder's shares purchasable hereunder.

            6.    Cash Election.

            (a)   In lieu of exercising the Option, by notice, Parent may
require such Stockholder to make a cash payment to Parent in the amount (the
"Cash Payment Amount") equal to the amount by which (A) the Market Price (as
defined below) exceeds (B) the Per Share Cash Amount, multiplied by the sum
of (i) the number of such Stockholder's Shares and (ii) the number of such
Stockholder's New Shares.  Upon receipt of such notice, the Stockholder shall
be permitted to sell a sufficient number of Shares to pay the Cash Payment
Amount, if Stockholder shall, within five business days of such notice, sell
such Shares, provided that Stockholder shall use reasonable best efforts to
achieve good execution and shall consult with Parent with respect to the
manner of disposition.  The term "Market Price" shall mean the closing price
(as measured by the last completed trade) for shares of Common Stock on the
date of Parent's election, or if

                                      -4-


<PAGE>

Stockholder elects to sell Shares to pay the Cash Payment Amount and has
complied with the proviso to the immediately preceding sentence, the average
price per Share actually realized in such sale.

            (b)   Parent may exercise its right to require such Stockholder
to pay the Cash Payment Amount pursuant to this Section by surrendering for
such purpose to such Stockholder, at the Company's principal office, a copy
of this Agreement, accompanied by a written notice or notices stating that
Parent elects to require such Stockholder to pay the Cash Payment Amount in
accordance with the provisions of this Section.  Within five (or, in the case
of a sale of Shares under (a) above to fund the Cash Payment Amount, eight)
business days after the surrender of the Option and the receipt of such
notice or notices relating thereto, such Stockholder shall deliver or cause
to be delivered to Parent the Cash Payment Amount by wire to the account
designated by Parent in immediately available funds.

            (c)   If Stockholder at any time after delivery of a notice of
election by Parent to take the Cash Payment Amount pursuant to this Section
is prohibited under applicable law or regulation from selling Shares in order
to deliver to Parent the Cash Payment Amount in full, and Stockholder is
required to sell Shares to fund the Cash Payment Amount, then (i) such
Stockholder hereby undertakes to use such Stockholder's reasonable best
efforts, to the extent within the control of such Stockholder, to obtain all
required regulatory and legal approvals and to file any required notices, in
each case as promptly as practicable in order to accomplish such sales and
(ii) if Stockholder is unable to effect sales within four days after the
receipt of notice, such Stockholder shall be permitted to pay the Cash
Payment Amount to Parent in Shares valued at the Market Price.

            7.    No Encumbrances.

            (a)   Except as expressly contemplated by this Agreement,
Stockholder's Shares and the certificates representing such Shares are now,
and at all times during the term hereof will be, held by such Stockholder, or
by a nominee or custodian for the benefit of such Stockholder, free and clear
of all liens, claims, security interests, proxies, voting trusts or
agreements, understandings or arrangements or any other encumbrances
whatsoever (other than to the extent set forth on Schedule 1 to this
Agreement), except for any such encumbrances or proxies arising hereunder.

            (b)   Notwithstanding the foregoing, any Stockholder which has
received a notice of election by Parent (or its designee) to receive the Cash
Payment Amount shall be permitted, between receipt of such notice and the
time on which the Cash Payment Amount is due to be paid, to sell such number
of Shares as may be necessary to satisfy such obligation, as described in
Section 6(a) above.

            (c)   Any transfer by Stockholder of its Shares to Parent
pursuant to the Option shall pass to and unconditionally vest in Parent good
and valid title to such Stockholder's Shares and New Shares, free and clear
of all claims, liens, restrictions, security interests, pledges, limitations
and encumbrances whatsoever.

<PAGE>

         8.    Acquisition Proposals.  Stockholder agrees that such
Stockholder (i) shall not, directly or indirectly, initiate, solicit,
encourage or otherwise facilitate any inquiries or the making of any
Acquisition Proposal and (ii) has terminated any discussions or negotiations
with, and the provision of information or data to, any Person (other than
Parent) respecting an Acquisition Proposal.  Such Stockholder further agrees
that he shall not, directly or indirectly, provide any confidential
information or data to any Person (as defined in the Merger Agreement)
relating to or in contemplation of an Acquisition Proposal or engage in any
negotiations or discussions relating to or in contemplation of an Acquisition
Proposal.  Such Stockholder will notify Parent immediately if any inquiries,
proposals or offers respecting an Acquisition Proposal are received by, any
such information or data is requested from, or any such discussions or
negotiations are sought to be initiated or continued with, such Stockholder
indicating, in connection with such notice, the name of such Person and the
material terms and conditions of any proposals or offers, and shall keep
Parent apprised with respect to the status and terms thereof.

            9.    Appraisal Rights.  Stockholder agrees not to exercise any
rights (including, without limitation, under Article 13 of the North Carolina
Business Corporation Act) to demand appraisal of any Common Stock which may
arise with respect to the Merger.

            10.   Affiliates Letter.  Stockholder shall execute and deliver
on a timely basis an Affiliate Letter (as defined in the Merger Agreement).

            11.   Reliance by Parent.  Stockholder understands and
acknowledges that Parent is entering into the Merger Agreement in reliance
upon Stockholder's execution and delivery of this Agreement.

            12.   Specific Performance.  Each party hereto severally
acknowledges that it will be impossible to measure in money the damage to the
other parties if the party hereto fails to comply with any of the obligations
imposed by this Agreement, that every such obligation is material and that,
in the event of any such failure, the other parties will not have an adequate
remedy at law or damages.  Accordingly, each party hereto severally agrees
that injunctive relief or other equitable remedy, in addition to remedies at
law or damages, is the appropriate remedy for any such failure and will not
oppose the granting of such relief on the basis that any other party has an
adequate remedy at law.  Each party hereto severally agrees that it will not
seek, and agrees to waive any requirement for, the securing or posting of a
bond in connection with any other party's seeking or obtaining such equitable
relief.

            13.   Heirs, Successors and Assigns.  This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their
respective heirs, successors and assigns and shall not be assignable without
the written consent of all other parties hereto other than any assignment in
whole or in part by Parent.

            14.   Entire Agreement.  This Agreement supersedes all prior
agreements, written or oral, among the parties hereto with respect to the
subject matter hereof and contains the entire agreement among the parties
with respect to the subject matter hereof.  This Agreement may not be
amended, supplemented or modified, and no provisions hereof may be modified
or

                                      -6-


<PAGE>

waived, except by an instrument in writing signed by all the parties hereto. No
waiver of any provisions hereof by any party shall be deemed a waiver of any
other provisions hereof by any such party, nor shall any such waiver be deemed a
continuing waiver of any provision hereof by such party.

            15.   Miscellaneous.

            (a)   Expenses.  Each of the parties hereto shall bear and pay
all costs and expenses incurred by it or on its behalf in connection with the
negotiation of this Agreement, including fees and expenses of its own
financial consultants, investment bankers, accountants and counsel.

            (b)   Amendment.  This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

            (c)   This Agreement shall be deemed a contract made under, and
for all purposes shall be construed in accordance with, the internal laws of
the State of New York without regard to principles of conflicts of law,
except for those provisions relating to the voting and the proxy which shall
be governed by North Carolina law.

            (d)   Severability.  If any provision of this Agreement or the
application of such provision to any person or circumstances shall be held
invalid by a court of competent jurisdiction, the remainder of the provision
held invalid and the application of such provision to persons or
circumstances, other than the party as to which it is held invalid, shall not
be affected.

            (e)   Counterparts.  This Agreement may be executed in one or
more counterparts, each of which shall be deemed to be an original but all of
which together shall constitute one and the same instrument.

            (f)   Termination.  This Agreement shall terminate upon
termination of the Option.

            (g)   Headings.  All Section headings herein are for convenience
of reference only and are not part of this Agreement and no construction or
reference shall be derived therefrom.

            (h)   Notices.  All notices, requests, claims, demands, and other
communications under this Agreement must be in writing and shall be deemed

                                FORM OF PROXY


            The undersigned stockholder, for consideration received, hereby
appoints [PARENT DESIGNEES] and each of them as my proxies, with full power
of substitution in each of them, to cast on behalf of the undersigned all
votes entitled to be cast by the holder of the shares of Class A Common
Stock, par value $0.01 per share, of Vanguard Cellular Systems, Inc., a North
Carolina corporation (the "Company"), owned by the undersigned at the Special
Meeting of Stockholders of the Company to be held [DATE, TIME AND PLACE] and
at any adjournment thereof (i) "FOR" approval and adoption of the Agreement
and Plan of Merger, dated as of October 2, 1998, between the Company and AT&T
Corp., a New York corporation ("Parent"), providing for the merger (the
"Merger") of the Company with and into a wholly-owned subsidiary of Parent,
and the Merger and (ii) "AGAINST" any proposal or offer with respect to a
merger, reorganization, share exchange, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving,
or any purchase of any substantial portion of the assets of, or any equity
securities of, or any transaction that would involve the transfer or
potential transfer of control of, the Company other than the Merger and any
proposed action or transaction that would prevent or intentionally delay
consummation of the Merger or is otherwise inconsistent therewith.  This
proxy is coupled with an interest and is irrevocable until such time as the
Voting Agreement, dated as of December 22, 1998, between a certain
stockholder of the Company, the undersigned, and Parent terminates in
accordance with its terms.

                               VOTING AGREEMENT


            VOTING AGREEMENT (the "Agreement"), dated as of December 22,
1998, between the undersigned stockholder ("Stockholder") of Vanguard
Cellular Systems, Inc., a North Carolina corporation (the "Company"), and
AT&T Corp., a New York corporation ("Parent").

            WHEREAS, prior to the execution and delivery of this Agreement,
the Company and Parent have entered into an Agreement and Plan of Merger
dated as of October 2, 1998 (the "Merger Agreement"), providing for the
merger of the Company with and into a wholly-owned subsidiary of Parent (the
"Merger") pursuant to the terms and conditions thereof; and

            WHEREAS, as an inducement and a condition to Parent entering into
the Merger Agreement, various stockholders of the Company signed voting
agreements with Parent, which agreements restrict the transfer of the Class A
Common Stock, par value $0.01 per share, of the Company (the "Common Stock")
owned by such stockholders; and

            WHEREAS, in accordance with such restrictions it is necessary for
Stockholder to sign this Agreement to receive certain shares of the Common
Stock;

            NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

            1.    Representations of Stockholder.  Stockholder represents
that:

            (a)   such Stockholder is or may become the beneficial owner of
the number of shares of Common Stock set forth opposite such Stockholder's
name on Exhibit A (such Stockholder's "Shares");

            (b)   except as may be denoted in Exhibit A, as of the date
hereof such Stockholder does not beneficially own (as such term is defined in
the Securities Exchange Act of 1934, as amended (the "1934 Act")) or own of
record any shares of Common Stock other than such Stockholder's Shares, but
excluding any shares of Common Stock which such Stockholder has the right to
obtain upon the exercise of stock options outstanding on the date hereof;

            (c)   such Stockholder has the right, power and authority to
execute and deliver this Agreement and to perform such Stockholder's
obligations under this Agreement, and this Agreement has been duly executed
and delivered by such Stockholder and constitutes a valid and legally binding
agreement of such Stockholder, enforceable in accordance with its terms; and
such execution, delivery and performance by such Stockholder of this
Agreement will not (i) conflict with, require a consent, waiver or approval
under, or result in a breach of or default under, any of the terms of any
contract, commitment or other obligation (written or oral) to which such
Stockholder is a party or by which such Stockholder is bound; (ii) violate
any order, writ, injunction, decree or statute, or any rule or regulation,
applicable to Stockholder or any of the properties or assets of Stockholder;
or (iii) result in the creation of, or impose any obligation 

<PAGE>

on such Stockholder to create, any Lien (as defined in the Merger Agreement),
charge or other encumbrance of any nature whatsoever upon the Shares, other than
in favor of Parent; and

            (d)   Haynes G. Griffin and Virginia R. Griffin are the sole
beneficiaries of the The Haynes G. Griffin 1998 Charitable Remainder Unitrust.

            The representations and warranties contained herein shall be made
as of the date hereof and as of each date from the date hereof through and
including the date that the Merger is consummated or this Agreement is
terminated in accordance with its terms.

            2.    Agreement to Vote Shares.  Stockholder shall be present (in
person or by proxy) at and vote his Shares and any New Shares (as defined in
Section 4 hereof), and shall cause any holder of record of his Shares or New
Shares to be present and vote, (a) in favor of adoption and approval of the
Merger Agreement and the Merger (and each other action and transaction
contemplated by the Merger Agreement or by this Agreement) and (b) against
any Acquisition Proposal (as defined in the Merger Agreement) other than the
Merger (or any other Acquisition Proposal of Parent) and against any proposed
action or transaction that would prevent or intentionally delay consummation
of the Merger (or other Acquisition Proposal of Parent) or is otherwise
inconsistent therewith at every meeting of the stockholders of the Company at
which any such matters are considered and at every adjournment thereof (and,
if applicable, in connection with any request or solicitation of written
consents of stockholders).  Any such vote shall be cast, or consent shall be
given, in accordance with such procedures relating thereto as shall ensure
that it is duly counted for purposes of determining that a quorum is present
and for purposes of recording the results of such vote or consent.
Stockholder shall deliver to Parent upon request a proxy substantially in the
form attached hereto as Exhibit B, which proxy shall be coupled with an
interest and irrevocable to the extent permitted under North Carolina law,
with the total number of such Stockholder's Shares and any New Shares
correctly indicated thereon.  Stockholder hereby revokes any and all previous
proxies granted with respect to his Shares.  Stockholder shall also use his
reasonable best efforts to take, or cause to be taken, all action, and do, or
cause to be done, all things necessary or advisable in order to consummate
and make effective the transactions contemplated by this Agreement.

            3.    No Voting Trusts.  After the date hereof, Stockholder
agrees that he will not, nor will he permit any entity under his control to,
deposit any Shares in a voting trust or subject any Shares to any Lien or
agreement, arrangement or understanding with respect to the voting of such
Shares other than agreements entered into with Parent.

            4.    Additional Purchases.  Stockholder agrees that in the event
(a) of any stock dividend, stock split, recapitalization, reclassification,
combination or exchange of shares of stock of the Company on, of or affecting
the Shares of such Stockholder, (b) such Stockholder purchases or otherwise
acquires beneficial ownership of any shares of Common Stock after the
execution of this Agreement (including by exercise of options), or (c) such
Stockholder acquires the right to vote or share in the voting of any shares
of Common Stock other than the Shares 

                                      -2-

<PAGE>

(collectively, "New Shares"), such Stockholder shall deliver promptly to Parent
upon request an irrevocable proxy substantially in the form attached hereto as
Exhibit B with respect to such New Shares. Stockholder also agrees that any New
Shares acquired or purchased by him shall be subject to the terms of this
Agreement and shall constitute Shares to the same extent as if they were owned
by such Stockholder on the date hereof.

            5.    Option Shares.

            (a)   Subject to the terms and conditions set forth herein,
Stockholder hereby grants to Parent an irrevocable option (the "Option") to
purchase, in whole or in part, such Stockholder's Shares and such
Stockholder's New Shares at a purchase price equal to the Per Share Cash
Amount (as defined in the Merger Agreement) per share; provided, however,
that if the Per Share Cash Amount under the Merger Agreement or any amendment
thereto is ever increased or if Parent shall otherwise offer to the
Stockholders of the Company an increased consideration for all of their
shares (the "Greater Consideration"), then the purchase price per share under
the Option shall be increased to equal such new Per Share Cash Amount or
Greater Consideration; and provided further that if Parent has exercised the
Option within 12 months prior to such increase in the Per Share Cash Amount
or Greater Consideration, then Parent shall pay to each Stockholder an amount
equal to the product of the number of shares previously purchased from such
Stockholder pursuant to the Option and the amount of increase between the old
Per Share Cash Amount and the new Per Share Cash Amount or Greater
Consideration, as applicable.

            (b)   Parent may exercise the Option, in whole or in part, at any
time and from time to time, after the first to occur of (i) any event as a
result of which Parent shall be entitled to receive a termination fee
pursuant to Section 7.2(e) of the Merger Agreement in the amount of $52.5
million pursuant to part (1) or part (2) of such Section or in the amount of
$22.5 million pursuant to part (3) of such Section or (ii) the breach by any
Stockholder of Section 2 of this Agreement (the first of such events to
occur, a "Purchase Event"); provided, however, that except as provided in the
last sentence of this Section 5(b), the Option shall terminate and be of no
further force and effect upon the earliest to occur of (A) the Effective Time
(as defined in the Merger Agreement), (B) 12 months and one day after the
occurrence of a termination of the Merger Agreement in accordance with
Section 7.1 (d), (e), (f) or (g), (C) a termination of the Merger Agreement
in accordance with Section 7.1(a), (b), (c) or (h) of the Merger Agreement
and (D) 18 months after the Outside Date as defined in Section 7.1(e) of the
Merger Agreement.  Notwithstanding the termination of the Option, Parent
shall be entitled to exercise the Option or receive the Cash Payment Amount
if it has given written notice of its intent to exercise the Option or
receive the Cash Payment Amount in accordance with the terms hereof prior to
the termination of the Option and the termination of the Option shall not
affect any rights hereunder which by their terms do not terminate or expire
prior to or as of such termination.

            (c)   In the event that Parent wishes to exercise the Option, it
shall send to such Stockholder a written notice (the date of which being
herein referred to as the "Notice Date") to that effect which notice also
specifies the total number of shares Parent will purchase pursuant to such
exercise, and a date not earlier than three business days nor later than 15
business days from 

                                      -3-
<PAGE>

the Notice Date for the closing of such purchase (the "Option Closing Date");
provided, however, that (i) if the closing of the purchase and sale pursuant to
the Option (the "Option Closing") cannot be consummated by reason of any
applicable judgment, decree, order, law or regulation (including, without
limitation, the rules and regulations of the FCC), the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which such restriction on consummation has expired or been terminated and (ii)
without limiting the foregoing, if prior notification to or approval of any
Governmental Entity (as defined in the Merger Agreement) is required in
connection with such purchase or any other transaction contemplated hereby,
Parent and such Stockholder shall promptly file the required notice or
application for approval and shall cooperate in the expeditious filing of such
notice or application, and, in the case of any prior notification or approval
required in connection with such purchase, the period of time that otherwise
would run pursuant to this sentence shall run instead from the date on which, as
the case may be, (A) any required notification period has expired or been
terminated or (B) any required approval has been obtained, and in either event,
any requisite waiting period has expired or been terminated. The place of the
Option Closing shall be at the offices of Wachtell, Lipton, Rosen & Katz, 51
West 52nd Street, New York, New York, and the time of the Option Closing shall
be 10:00 a.m. (Eastern Time) on the Option Closing Date.

            (d)   At the Option Closing, Parent (or its designee) shall pay
to each Stockholder an amount equal to the product of (x) the Per Share Cash
Amount or Greater Consideration, as applicable, and (y) the number of shares
being purchased from such Stockholder pursuant to the exercise of the
Option.  Such payment shall be in immediately available funds by wire
transfer to a bank account designated in writing by such Stockholder.

            (e)   At the Option Closing, simultaneously with the delivery of
the amount specified in Section 5(d), each Stockholder shall deliver to
Parent (or its designee) a certificate or certificates representing its
shares to be purchased at the Option Closing, which shares shall be free and
clear of all Liens, claims, charges and encumbrances of any kind whatsoever,
except for such encumbrances or proxies in favor of Parent arising hereunder,
and a new Option evidencing the rights of the Parent (or its designee) to
purchase the balance of such Stockholder's shares purchasable hereunder.

            6.    Cash Election.

            (a)   In lieu of exercising the Option, by notice, Parent may
require such Stockholder to make a cash payment to Parent in the amount (the
"Cash Payment Amount") equal to the amount by which (A) the Market Price (as
defined below) exceeds (B) the Per Share Cash Amount, multiplied by the sum
of (i) the number of such Stockholder's Shares and (ii) the number of such
Stockholder's New Shares.  Upon receipt of such notice, the Stockholder shall
be permitted to sell a sufficient number of Shares to pay the Cash Payment
Amount, if Stockholder shall, within five business days of such notice, sell
such Shares, provided that Stockholder shall use reasonable best efforts to
achieve good execution and shall consult with Parent with respect to the
manner of disposition.  The term "Market Price" shall mean the closing price
(as measured by the last completed trade) for shares of Common Stock on the
date of Parent's election, or if 

                                      -4-


<PAGE>

Stockholder elects to sell Shares to pay the Cash Payment Amount and has
complied with the proviso to the immediately preceding sentence, the average
price per Share actually realized in such sale.

            (b)   Parent may exercise its right to require such Stockholder
to pay the Cash Payment Amount pursuant to this Section by surrendering for
such purpose to such Stockholder, at the Company's principal office, a copy
of this Agreement, accompanied by a written notice or notices stating that
Parent elects to require such Stockholder to pay the Cash Payment Amount in
accordance with the provisions of this Section.  Within five (or, in the case
of a sale of Shares under (a) above to fund the Cash Payment Amount, eight)
business days after the surrender of the Option and the receipt of such
notice or notices relating thereto, such Stockholder shall deliver or cause
to be delivered to Parent the Cash Payment Amount by wire to the account
designated by Parent in immediately available funds.

            (c)   If Stockholder at any time after delivery of a notice of
election by Parent to take the Cash Payment Amount pursuant to this Section
is prohibited under applicable law or regulation from selling Shares in order
to deliver to Parent the Cash Payment Amount in full, and Stockholder is
required to sell Shares to fund the Cash Payment Amount, then (i) such
Stockholder hereby undertakes to use such Stockholder's reasonable best
efforts, to the extent within the control of such Stockholder, to obtain all
required regulatory and legal approvals and to file any required notices, in
each case as promptly as practicable in order to accomplish such sales and
(ii) if Stockholder is unable to effect sales within four days after the
receipt of notice, such Stockholder shall be permitted to pay the Cash
Payment Amount to Parent in Shares valued at the Market Price.

            7.    No Encumbrances.

            (a)   Except as expressly contemplated by this Agreement,
Stockholder's Shares and the certificates representing such Shares are now,
and at all times during the term hereof will be, held by such Stockholder, or
by a nominee or custodian for the benefit of such Stockholder, free and clear
of all liens, claims, security interests, proxies, voting trusts or
agreements, understandings or arrangements or any other encumbrances
whatsoever (other than to the extent set forth on Schedule 1 to this
Agreement), except for any such encumbrances or proxies arising hereunder.

            (b)   Notwithstanding the foregoing, any Stockholder which has
received a notice of election by Parent (or its designee) to receive the Cash
Payment Amount shall be permitted, between receipt of such notice and the
time on which the Cash Payment Amount is due to be paid, to sell such number
of Shares as may be necessary to satisfy such obligation, as described in
Section 6(a) above.

            (c)   Any transfer by Stockholder of its Shares to Parent
pursuant to the Option shall pass to and unconditionally vest in Parent good
and valid title to such Stockholder's Shares and New Shares, free and clear
of all claims, liens, restrictions, security interests, pledges, limitations
and encumbrances whatsoever.

                                      -5-
<PAGE>

            8.    Acquisition Proposals.  Stockholder agrees that such
Stockholder (i) shall not, directly or indirectly, initiate, solicit,
encourage or otherwise facilitate any inquiries or the making of any
Acquisition Proposal and (ii) has terminated any discussions or negotiations
with, and the provision of information or data to, any Person (other than
Parent) respecting an Acquisition Proposal.  Such Stockholder further agrees
that he shall not, directly or indirectly, provide any confidential
information or data to any Person (as defined in the Merger Agreement)
relating to or in contemplation of an Acquisition Proposal or engage in any
negotiations or discussions relating to or in contemplation of an Acquisition
Proposal.  Such Stockholder will notify Parent immediately if any inquiries,
proposals or offers respecting an Acquisition Proposal are received by, any
such information or data is requested from, or any such discussions or
negotiations are sought to be initiated or continued with, such Stockholder
indicating, in connection with such notice, the name of such Person and the
material terms and conditions of any proposals or offers, and shall keep
Parent apprised with respect to the status and terms thereof.

            9.    Appraisal Rights.  Stockholder agrees not to exercise any
rights (including, without limitation, under Article 13 of the North Carolina
Business Corporation Act) to demand appraisal of any Common Stock which may
arise with respect to the Merger.

            10.   Affiliates Letter.  Stockholder shall execute and deliver
on a timely basis an Affiliate Letter (as defined in the Merger Agreement).

            11.   Reliance by Parent.  Stockholder understands and
acknowledges that Parent is entering into the Merger Agreement in reliance
upon Stockholder's execution and delivery of this Agreement.

            12.   Specific Performance.  Each party hereto severally
acknowledges that it will be impossible to measure in money the damage to the
other parties if the party hereto fails to comply with any of the obligations
imposed by this Agreement, that every such obligation is material and that,
in the event of any such failure, the other parties will not have an adequate
remedy at law or damages.  Accordingly, each party hereto severally agrees
that injunctive relief or other equitable remedy, in addition to remedies at
law or damages, is the appropriate remedy for any such failure and will not
oppose the granting of such relief on the basis that any other party has an
adequate remedy at law.  Each party hereto severally agrees that it will not
seek, and agrees to waive any requirement for, the securing or posting of a
bond in connection with any other party's seeking or obtaining such equitable
relief.

            13.   Heirs, Successors and Assigns.  This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their
respective heirs, successors and assigns and shall not be assignable without
the written consent of all other parties hereto other than any assignment in
whole or in part by Parent.

            14.   Entire Agreement.  This Agreement supersedes all prior
agreements, written or oral, among the parties hereto with respect to the
subject matter hereof and contains the entire agreement among the parties
with respect to the subject matter hereof.  This Agreement may not be
amended, supplemented or modified, and no provisions hereof may be modified or

                                      -6-


<PAGE>

waived, except by an instrument in writing signed by all the parties hereto. No
waiver of any provisions hereof by any party shall be deemed a waiver of any
other provisions hereof by any such party, nor shall any such waiver be deemed a
continuing waiver of any provision hereof by such party.

            15.   Miscellaneous.

            (a)   Expenses.  Each of the parties hereto shall bear and pay
all costs and expenses incurred by it or on its behalf in connection with the
negotiation of this Agreement, including fees and expenses of its own
financial consultants, investment bankers, accountants and counsel.

            (b)   Amendment.  This Agreement may not be amended, except by an
instrument in writing signed on behalf of each of the parties.

            (c)   This Agreement shall be deemed a contract made under, and
for all purposes shall be construed in accordance with, the internal laws of
the State of New York without regard to principles of conflicts of law,
except for those provisions relating to the voting and the proxy which shall
be governed by North Carolina law.

            (d)   Severability.  If any provision of this Agreement or the
application of such provision to any person or circumstances shall be held
invalid by a court of competent jurisdiction, the remainder of the provision
held invalid and the application of such provision to persons or
circumstances, other than the party as to which it is held invalid, shall not
be affected.

            (e)   Counterparts.  This Agreement may be executed in one or
more counterparts, each of which shall be deemed to be an original but all of
which together shall constitute one and the same instrument.

            (f)   Termination.  This Agreement shall terminate upon
termination of the Option.

            (g)   Headings.  All Section headings herein are for convenience
of reference only and are not part of this Agreement and no construction or
reference shall be derived therefrom.

            (h)   Notices.  All notices, requests, claims, demands, and other
communications under this Agreement must be in writing and shall be deemed

of substitution in each of them, to cast on behalf of the undersigned all
votes entitled to be cast by the holder of the shares of Class A Common

Meeting of Stockholders of the Company to be held [DATE, TIME AND PLACE] and
at any adjournment thereof (i) "FOR" approval and adoption of the Agreement
and Plan of Merger, dated as of October 2, 1998, between the Company and AT&T
Corp., a New York corporation ("Parent"), providing for the merger (the
"Merger") of the Company with and into a wholly-owned subsidiary of Parent,
and the Merger and (ii) "AGAINST" any proposal or offer with respect to a
merger, reorganization, share exchange, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving,
or any purchase of any substantial portion of the assets of, or any equity
securities of, or any transaction that would involve the transfer or
potential transfer of control of, the Company other than the Merger and any
proposed action or transaction that would prevent or intentionally delay
consummation of the Merger or is otherwise inconsistent therewith.  This
proxy is coupled with an interest and is irrevocable until such time as the
Voting Agreement, dated as of December 22, 1998, between a certain
stockholder of the Company, the undersigned, and Parent terminates in
accordance with its terms.
