THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO
                     CERTAIN RESTRICTIONS CONTAINED HEREIN.

                                OPTION AGREEMENT

         This OPTION  AGREEMENT,  dated as of the 22nd day  of August, 1996,
between SOUTHERN NATIONAL CORPORATION ("SNC"), a North Carolina corporation, and
FIDELITY FINANCIAL BANKSHARES CORPORATION ("Fidelity"), a Virginia corporation;

                                R E C I T A L S:

         The Boards of Directors of SNC and Fidelity  have approved an Agreement
and  Plan  of  Reorganization  (the  "Reorganization  Agreement"),  dated  as of
August 22, 1996,  between SNC and  Fidelity,  providing  for the merger of
Fidelity into BB&T Financial-Virginia, a subsidiary of SNC (the "Merger"), which
Reorganization Agreement has been executed by the parties concurrently with this
Agreement.  As a condition to SNC's execution of the  Reorganization  Agreement,
and in consideration thereof, Fidelity has agreed to grant to SNC the option set
forth herein.

         NOW, THEREFORE, in consideration of the premises herein contained,  the
parties agree as follows:

         1.  Definitions.   Capitalized  terms  defined  in  the  Reorganization
Agreement and used herein shall have the same meanings as in the  Reorganization
Agreement.

         2.  Grant of  Option.  Fidelity  hereby  grants to SNC an  option  (the
"Option") to purchase up to 456,044 shares of authorized but unissued  shares of
Fidelity  Common  Stock at a price of $13.00  per share (the  "Exercise  Price")
payable in cash as provided in Section 4; provided, however, that such number of
shares  shall be reduced if and to the  extent  necessary  so that the number of
shares for which this Option is exercisable shall not exceed 19.9% of the issued
and  outstanding  Fidelity  Common Stock,  as of the date hereof.  The number of
shares of Fidelity  Common  Stock that may be received  upon the exercise of the
Option is subject to adjustment as set forth herein.

         3. Exercise of Option.

            (a) Subject to compliance with applicable law and  regulations,  and
unless SNC shall have  breached in any  material  respect and failed to cure any
covenant or representation in the Reorganization Agreement, SNC may exercise the
Option,  in whole or in part,  at any time or from  time to time  following  the
occurrence of a Purchase Event (as defined below) and prior to the occurrence of
a Termination Event (as defined below).



                                     - 1 -





            (b) (i) As used herein, "Purchase Event" shall mean when:

                  (A)  Fidelity  or  the  Subsidiary   shall  have   authorized,
recommended, proposed or publicly announced an intention to authorize, recommend
or propose a transaction with a person (other than SNC or its affiliates) to, or
entered into an agreement with a person (other than SNC or its  affiliates)  to:
(a) effect a merger or  consolidation  with, or enter into any similar  business
combination  with,  Fidelity or the  Subsidiary,  (b) sell,  lease or  otherwise
dispose of the assets of Fidelity to such person  aggregating 10% or more of the
consolidated  assets of Fidelity and the  Subsidiary  (other than a sale of loan
receivables  in a  financing  transaction  in  the  normal  course  of  business
consistent with past practices),  or (c) issue,  sell or otherwise dispose of to
such person  (including by way of merger,  consolidation,  share exchange or any
similar transaction)  securities representing more than 10 percent of the voting
power of Fidelity or the Subsidiary; or

                  (B) any person other than SNC or any of its Subsidiaries shall
have acquired  beneficial  ownership of more than 10 percent of the  outstanding
shares of Fidelity Common Stock;  or any person shall have merged,  consolidated
with or consummated a similar transaction with Fidelity or any person shall have
purchased,  leased or otherwise acquired 10% of more of Fidelity's assets (other
than a sale of loan receivables in a financing  transaction in the normal course
of business consistent with past practices); or


                  (C) a bona fide proposal is made by any person (other than SNC
or its Affiliates) by public  announcement or written  communication  that is or
becomes the subject of public disclosure, or disclosure in an application to any
federal or state  regulatory  authority,  to (a) acquire,  merge or  consolidate
with, or enter into any similar transaction with Fidelity,  (b) purchase,  lease
or otherwise acquire 10% or more of the assets of Fidelity (other than a sale of
loan  receivables  in a financing  transaction),  or (c)  purchase or  otherwise
acquire  (including  by  way  of  tender  offer,  merger,  consolidation,  share
exchange,  tender  or  exchange  offer or any  similar  transaction)  securities
representing more than 10 percent of the voting power of Fidelity;

                  (ii) The term  "person"  shall have the meaning  specified  in
Section 3(a)(9),  and "beneficial  ownership"  shall have the meaning  specified
under Section 13(d)(3), of the Exchange Act.

                  (c)  Fidelity  shall  notify  SNC  promptly  in writing of the
occurrence of any transaction, offer or event giving rise to a Purchase Event.

                  (d) In the event SNC wishes to exercise  the Option,  it shall
send to Fidelity a written notice (an "Exercise Notice," the date of which being
herein  referred to as the "Notice  Date")  specifying  (i) the total  number of
shares SNC will purchase  pursuant to such  exercise,  and (ii) a place and date
not earlier than three  business  days nor later than 20 business  days from the
Notice Date for the closing of such  purchase with respect to such exercise (the
"Option  Closing  Date");  provided that if the closing of the purchase and sale
pursuant  to the  Option  cannot be  consummated  by  reason  of any  applicable
judgment,  decree,  order, law or regulation,  the period of time that otherwise
would run  pursuant to this  sentence  shall run instead  from the date on which
such restriction on


                                     - 2 -





consummation  has expired or been  terminated;  and  provided  further,  without
limiting the foregoing, if prior notification to, or approval of, any federal or
state regulatory  agency is required in connection with such purchase,  SNC, and
Fidelity if required by applicable  law, shall promptly file the required notice
or  application  for approval and shall  expeditiously  process the same and the
period of time that  otherwise  would run  pursuant to this  sentence  shall run
instead from the date on which the last required notification period has expired
or been  terminated  or such  approvals  have been  obtained  and any  requisite
waiting periods shall have passed.

                  (e) The Option shall expire and terminate, to the extent not
previously exercised, upon the earliest of (a "Termination Event"):

                          (i) the Effective Time of the Merger; or

                          (ii) the termination of the Reorganization Agreement
without a Purchase Event having occurred,  other than a termination  based upon,
following,  or in connection with,  either (A) a willful and material breach by
Fidelity of any of its covenants or agreements in the Reorganization  Agreement,
or (B) the failure of Fidelity to obtain shareholder  approval of the
transactions  contemplated by the Reorganization Agreement by the vote required
under applicable law; or

                           (iii) 18 months after the first occurrence of a
Purchase Event; or

                           (iv) 36 months after the date hereof.

                  (f)  Notwithstanding  the termination of the Option, SNC shall
be entitled to purchase  any shares with respect to which it has  exercised  the
Option in  accordance  with the terms  hereof  prior to the  termination  of the
Option.  The  termination  of the Option  shall not affect any rights  hereunder
which by their terms extend beyond the date of such termination.

         4. Payment and Delivery of Certificates.

                  (a) On each Option Closing Date, SNC shall pay to Fidelity the
aggregate  purchase price for the shares being  purchased on that Option Closing
Date  in  immediately  available  funds  by  a  wire  transfer  to  a  financial
institution designated by Fidelity.

                  (b) At each  closing  relating  to an  exercise of the Option,
simultaneously  with the delivery of cash by SNC as provided in  subsection  (a)
with  respect to the Option,  Fidelity  shall  deliver to SNC a  certificate  or
certificates representing the number of shares of Fidelity purchased by SNC, and
SNC shall deliver to Fidelity a letter  agreeing that SNC will not offer to sell
or  otherwise  dispose of such  shares in  violation  of  applicable  law or the
provisions  of  this  Option  Agreement  and  providing  such  undertakings  and
representations  as  necessary  for the  issuance  and sale of such shares to be
exempt from registration under applicable securities laws.


                                     - 3 -





         5. Representations.  Fidelity hereby represents and warrants to, and
covenants with, SNC as follows:

                  (a) Fidelity has all requisite  corporate  power and authority
to enter into this Option  Agreement and,  subject to any approvals  referred to
herein, to consummate the transactions  contemplated  hereby.  The execution and
delivery of this  Option  Agreement  and the  consummation  of the  transactions
contemplated  hereby have been duly authorized by all necessary corporate action
on the part of  Fidelity.  This  Option  Agreement  has been duly  executed  and
delivered  by  Fidelity  and  constitutes  a valid  and  binding  obligation  of
Fidelity, enforceable in accordance with its terms.

                  (b)  Fidelity  has taken  all  necessary  corporate  action to
authorize and reserve for issuance the full number of shares of Fidelity  Common
Stock  issuable upon exercise of the Option,  and shall continue to reserve such
shares until the Option is exercised or until this  Agreement is  terminated  as
provided herein.

                  (c) The shares to be issued upon due exercise,  in whole or in
part, of the Option,  when paid for as provided herein, will be duly authorized,
validly  issued,  fully paid and  nonassessable  and shall be delivered free and
clear of all  liens,  claims,  charges  and  encumbrances  of any kind or nature
whatsoever,  including any preemptive rights of any shareholder of Fidelity, but
subject to restrictions on transfer imposed by applicable securities laws.

                  (d) The execution and delivery of this Option  Agreement  does
not, and the  consummation  of the  transactions  contemplated  hereby will not,
conflict  with or result in any  violation  of any  provision of the Articles of
Incorporation  or By-laws of Fidelity or the Subsidiary or, subject to obtaining
any approvals or consents  contemplated  hereby,  result in any violation of any
loan or credit agreement,  note,  mortgage,  indenture,  lease,  benefit plan or
other agreement, obligation, instrument, permit, concession, franchise, license,
judgment,  order, decree, statute, law, ordinance, rule or regulation applicable
to Fidelity or the  Subsidiary  or their  respective  properties or assets which
violation  would,  individually  or in the  aggregate,  have a Material  Adverse
Effect.

                  (e) The provisions of the Virginia  Control Share  Acquisition
Act do not and will not apply to this Option Agreement or the purchase of shares
of Fidelity Common Stock pursuant to this Option Agreement.

         6. Adjustment upon Changes in Capitalization,  etc. In the event of any
change in the outstanding  Fidelity  Common Stock by reason of stock  dividends,
split-ups, mergers, recapitalizations,  combinations, exchanges of shares or the
like,  the number of shares  subject to the  Option and its  purchase  price per
share shall be adjusted appropriately so that the Option will entitle the holder
thereof to acquire,  at a price  economically  equivalent to the Exercise Price,
all of the shares or other securities, property, or rights to which ownership of
the  underlying  shares of Fidelity  Common Stock would have entitled the holder
had they been outstanding  immediately  prior to such change.  In the event that
any shares of Fidelity  Common Stock are issued after the date of this Agreement
other than in a transaction described in the first sentence of this Section 6 or
pursuant to


                                     - 4 -





the exercise of the Option,  the number of shares subject to the Option shall be
adjusted so that,  immediately after such issuance, the number of shares subject
to the Option  (together with the number of shares  previously  issued under the
Option)  equals  19.9  percent  (subject to  reduction  as provided in Section 2
hereof) of the number of the  then-outstanding  shares of Fidelity Common Stock.
Nothing  contained in this  Section 6 shall be deemed to  authorize  Fidelity to
breach any provision of the Reorganization Agreement or the Plan of Merger.

         7. Registration Rights. Fidelity shall, if requested by SNC at any time
and from time to time within two years of the first  exercise of the Option,  as
expeditiously as possible,  prepare and file a registration  statement under the
Securities Act if such  registration is necessary in order to permit the sale or
other  disposition of any or all shares or securities that have been acquired by
or are  issuable  to SNC upon  exercise  of the  Option in  accordance  with the
intended method of sale or other disposition  stated by SNC, including a "shelf"
registration  statement under Rule 415 under the Securities Act or any successor
provision.  Fidelity  shall use its best efforts to qualify such shares or other
securities   under  any  applicable   state   securities  laws,  to  cause  such
registration statement to become effective, to obtain all consents or waivers of
other  parties  which  are  required  therefor,  and to keep  such  registration
statement  effective for such period not in excess of 360 days from the day such
registration statement first becomes effective as may be reasonably necessary to
effect such sale or other disposition.  The obligations of Fidelity hereunder to
file a registration statement and to maintain its effectiveness may be suspended
for one or more periods of time not  exceeding  60 days in the  aggregate if the
Board of Directors  of Fidelity  shall have  determined  that the filing of such
registration  statement or the  maintenance of its  effectiveness  would require
disclosure of nonpublic  information  that would materially and adversely affect
Fidelity.  Any registration  statement  prepared and filed under this Section 7,
and any  sale  covered  thereby,  shall  be at  Fidelity's  expense  except  for
underwriting   discounts  or  commissions,   brokers'  fees  and  the  fees  and
disbursements  of  SNC's  counsel  related   thereto.   SNC  shall  provide  all
information  reasonably  requested by Fidelity for inclusion in any registration
statement to be filed  hereunder.  If during the time periods referred to in the
first  sentence  of this  Section 7 Fidelity  effects a  registration  under the
Securities  Act of  Fidelity  Common  Stock for its own account or for any other
stockholders  of Fidelity  (other than on Form S-4 or Form S-8, or any successor
form),  it shall allow SNC the right to  participate in such  registration,  and
such  participation  shall not affect the  obligation  of Fidelity to effect two
registration  statements  for SNC under this Section 7;  provided  that,  if the
managing  underwriters of such offering advise Fidelity in writing that in their
opinion the number of shares of Fidelity  Common Stock  requested to be included
in such  registration  exceeds  the number  which can be sold in such  offering,
Fidelity shall include the shares  requested to be included  therein by SNC only
to the maximum extent such managing  underwriter  determines to be feasible.  In
connection  with any  registration  pursuant to this Section 7, Fidelity and SNC
shall  provide each other and any  underwriter  of the offering  with  customary
representations,  warranties,  covenants,  indemnification  and  contribution in
connection with such registration.

         8. Listing.  If Fidelity Common Stock or any other securities to be
acquired upon exercise of the Option are then listed on The NASDAQ National
Market or any other national market or exchange, Fidelity, upon the request of
SNC, will promptly file an application to list the shares of


                                     - 5 -





Fidelity  Common Stock or other  securities  to be acquired upon exercise of the
Option on The NASDAQ  National  Market or such other market or exchange and will
use its best efforts to obtain approval of such listing as soon as practicable.

         9. Division of Option.  This Option  Agreement  (and the Option granted
hereby)  are  exchangeable,   without  expense,  at  the  option  of  SNC,  upon
presentation  and surrender of this Option  Agreement at the principal office of
Fidelity for other Agreements  providing for Options of different  denominations
entitling  the holder  thereof to purchase in the  aggregate  the same number of
shares of Fidelity Common Stock purchasable hereunder. The terms "Agreement" and
"Option" as used herein  include any other  Agreements  and related  Options for
which this  Agreement  (and the Option  granted  hereby) may be exchanged.  Upon
receipt by  Fidelity  of  evidence  reasonably  satisfactory  to it of the loss,
theft,  destruction or mutilation of this  Agreement,  and (in the case of loss,
theft or  destruction)  of  reasonably  satisfactory  indemnification,  and upon
surrender  and  cancellation  of this  Agreement,  if  mutilated,  Fidelity will
execute  and  deliver a new  Agreement  of like  tenor  and  date.  Any such new
Agreement  executed and delivered  shall  constitute  an additional  contractual
obligation  on the  part of  Fidelity,  whether  or not the  Agreement  so lost,
stolen, destroyed or mutilated shall at any time be enforceable by anyone.

         10. Severability.  If any term, provision, covenant or restriction
contained in this Option Agreement is held by a court or a federal or state
regulatory agency of competent jurisdiction to be invalid,  void  or
unenforceable,  the  remainder  of  the  terms,  provisions, covenants and
restrictions  contained in this Option  Agreement shall remain in full force and
effect, and shall in no way be affected, impaired or invalidated. If for any
reason such court or  regulatory  agency  determines  that the Option will not
permit the holder to  acquire  the full  number of shares of  Fidelity Common
Stock  provided in Section 2 hereof (as  adjusted  pursuant to Section 6
hereof),  it is the express intention of Fidelity to allow the holder to acquire
such lesser  number of shares as may be  permissible,  without any  amendment or
modification hereof.

         11. Miscellaneous.

                  (a) Expenses. Except as otherwise provided herein, each of the
parties  hereto shall bear and pay all costs and  expenses  incurred by it or on
its behalf in connection with the transactions contemplated hereunder, including
fees  and  expenses  of  its  own  financial  consultants,  investment  bankers,
accountants and counsel.

                  (b) Entire Agreement.  Except as otherwise expressly provided
herein, this Agreement contains the entire agreement between the parties with
respect to the transactions contemplated  hereunder and supersedes all prior
arrangements or understandings with  respect  thereto,  written  or oral.  The
terms  and  conditions  of this Agreement  shall inure to the benefit of and be
binding upon the parties  hereto and  their  respective  successors.  Nothing
in this  Agreement,  expressed  or implied,  is intended to confer upon any
party,  other than the parties  hereto, and their respective successors and
assigns, any rights,  remedies,  obligations or  liabilities  under or by
reason  of this  Agreement,  except  as  expressly provided herein.


                                     - 6 -





                  (c)  Assignment.  Neither of the parties hereto may assign any
of its rights or obligations  under this Agreement to any other person,  without
the express  written  consent of the other party,  except that SNC may assign in
whole or in part the Option and other benefits and obligations hereunder without
limitation to any of its wholly owned  subsidiaries  and SNC may assign in whole
or in part the Option  and other  benefits  and  obligations  hereunder  without
limitation  if a Purchase  Event has  occurred  and SNC shall have  delivered to
Fidelity a copy of a letter from the staff of the  Commission,  or an opinion of
counsel,  in form and  substance  reasonably  satisfactory  to Fidelity,  to the
effect that such Assignment will not violate the  requirements of the Securities
Act; provided, that prior to any such assignment,  SNC shall give written notice
of the proposed  assignment to Fidelity,  and within 24 hours of receipt of such
notice of a bona fide proposed assignment, Fidelity may purchase the Option at a
price and on other terms at least as  favorable  to SNC as that set forth in the
notice of assignment.

                  (d)  Notices.  All notices or other  communications  which are
