                                                 PLEDGE AGREEMENT


         THIS  PLEDGE  AGREEMENT,  dated as of December  __, 1998 (this  "Pledge
Agreement" or this  "Agreement"),  is made by  _________________,  an individual
residing in North Carolina (the "Pledgor"), for the benefit of Vanguard Cellular
Systems, Inc., a North Carolina corporation (the "Company").

         WHEREAS, the Company is party to a 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  Company,  pursuant to which the Company will be
merged with and into Winston, Inc. (the "Merger").

         WHEREAS, (i) pursuant to certain employment,  severance and termination
arrangements  between the Company and certain of its  employees,  including  the
Pledgor,  and as contemplated by Section  5.5(c)(i) of the Merger  Agreement and
items 6 and 7 of Schedule  4.1(e)(vi) to the Merger Agreement,  (ii) pursuant to
certain  tax  reimbursement  agreements  between  the Company and certain of its
employees,  including the Pledgor, and as contemplated by Section 5.5(c)(ii) of,
and the related Schedule  5.5(c)(ii) to, the Merger Agreement and (iii) pursuant
to  Section  1.7(b)  of the  Merger  Agreement,  the  Pledgor  may be  entitled,
following  consummation  of the Merger,  to certain change in control  severance
payments and/or tax  reimbursement  payments as well as certain cash payments in
respect of the shares of the  Company's  Common Stock to be  purchased  with the
proceeds of the  Exercise  Price  Loans  referred  to below  (collectively,  the
"Merger Payments") from Winston, Inc., as successor by merger to the Company.

         WHEREAS,  the  Company  has this date  made,  and may from time to time
hereafter make, a loan or loans (each a "Loan", and, collectively,  the "Loans")
to the  Pledgor,  the  proceeds of which  Loans are to be applied  either (i) to
payment  of the  exercise  price of stock  options  of the  Company  held by the
Pledgor  (the  "Exercise  Price  Loans")  or  (ii)  to  payment  of  income  tax
obligations of the Pledgor in connection  with such stock option  exercises (the
"Tax  Loans"),  each such Loan to be evidenced  by a Promissory  Note of Pledgor
payable to the Company (collectively, the "Notes").

         WHEREAS,  it is a condition to the  Company's  making of the Loans that
the Pledgor  enter into this Pledge  Agreement in favor of the  Company:  (i) to
secure the Pledgor's  obligations to pay principal,  interest,  and any fees and
expenses  or  other  amounts   payable  under  the  Notes   (collectively,   the
"Obligations")  by pledging to the Company all of the Class A Common Stock,  par
value  $0.01 per share,  (the  "Common  Stock") of the  Company  acquired by the
Pledgor upon the exercise of any stock  options  financed in whole or in part as
contemplated by the foregoing recital and (ii) to authorize the Company to apply
the Merger Payments to the prepayment of the Notes.

         NOW,  THEREFORE,  for good and valuable  consideration,  the receipt of
which is hereby acknowledged, it is agreed as follows:








         1. PLEDGE.  As  collateral  security  for the full and timely  payment,
performance  and  observance  of the  Obligations,  whether  now  or  previously
existing or hereafter arising,  the Pledgor herewith deposits,  pledges with and
hypothecates to the Company,  in form  transferable for delivery,  and grants to
the Company a security interest in, those shares of the outstanding Common Stock
and the  certificates or other  instruments or documents  evidencing such Common
Stock set forth on Exhibit A attached  hereto  (together  with a stock  transfer
power duly  endorsed in blank with  signature  guaranteed)  and such  additional
property as may at any time and from time to time be  receivable  by the Company
hereunder or otherwise  distributed  in respect of or in exchange for any or all
of such shares or into which such  shares may be  converted,  including  without
limitation any cash and/or  securities  receivable (or any right to receive such
consideration) in connection with the Merger (herein collectively referred to as
the "Pledged  Securities"),  together  with any and all proceeds and products of
any of the foregoing in whatever form (the Pledged  Securities  and the proceeds
and  products   thereof  may  be  referred  to   collectively  as  the  "Pledged
Collateral").

         2. PREPAYMENT FROM MERGER PAYMENTS.  The Pledgor authorizes and directs
the Company,  and its successor by merger,  Winston,  Inc., as pledgee, to apply
any and all Merger  Payments to the immediate  prepayment  of the Notes,  to the
extent of any  Obligations  (regardless of whether such Notes or Obligations are
due or payable at such time). Merger Payments shall be applied by the Company to
the  Obligations  as follows:  (a) first,  to any fees and expenses  accrued and
payable under any Notes evidencing  Exercise Price Loans, (b) second, to accrued
and unpaid interest on Exercise Price Loans, (c) third, to outstanding principal
of Exercise Price Loans (in inverse order of maturity of the related Notes), (d)
fourth,  to any fees and expenses accrued and payable under any Notes evidencing
Tax Loans, (e) fifth, to accrued and unpaid interest on Tax Loans, (f) sixth, to
outstanding  principal of Tax Loans (in inverse order of maturity of the related
Notes) and (g) seventh, to the Pledgor in accordance with Section 12 hereof.

         In  furtherance  of this  Section 2, the Pledgor  agrees (i) to vote in
favor of the Merger and refrain from  exercising  any  dissenter's  or appraisal
rights  and (ii) to cause the Merger  Payments  (as well as any shares of common
stock  of  AT&T  Corp.  received  in the  Merger  with  respect  to the  Pledged
Securities)  to be  delivered to the Company as pledgee,  at 2002 Pisgah  Church
Road,  Suite 300,  Greensboro,  North Carolina  27455,  by so completing the box
entitled "Special  Delivery  Instructions" on the Form of Election and Letter of
Transmittal relating to the Merger and delivering it to the Company prior to the
Merger, which Special Delivery Instructions shall then be irrevocable so long as
any Notes remain  outstanding.  The Company agrees to forward promptly such Form
of 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 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

                                                       - 2 -






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.

         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 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

                                                       - 3 -






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 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

                                                       - 4 -






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.

         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.


                                                       - 5 -






         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.
