EXHIBIT 99.3


                             STOCK OPTION AGREEMENT

       THIS STOCK OPTION  AGREEMENT (this  "Agreement") is made and entered into
as of October 28,  1998,  by and  between  First  Coastal  Bankshares,  Inc.,  a
Virginia  corporation  ("Issuer"),  and Centura  Banks,  Inc., a North  Carolina
corporation ("Grantee").

       WHEREAS,  Grantee and Issuer have entered into that certain Agreement and
Plan of Merger, dated as of October 28, 1998 (the "Merger Agreement"), providing
for,  among  other  things,  the merger of Issuer  with and into  Grantee,  with
Grantee as the surviving entity; and

       WHEREAS,  as a condition  and  inducement  to Grantee's  execution of the
Merger Agreement, Grantee has required that Issuer agree, and Issuer has agreed,
to grant Grantee the Option (as defined below);

       Now,  THEREFORE,  in  consideration  of the  respective  representations,
warranties,  covenants  and  agreements  set  forth  herein  and in  the  Merger
Agreement, and intending to be legally bound hereby, Issuer and Grantee agree as
follows:

       1.    Defined  Terms.  Capitalized  terms which are used but not  defined
herein  shall have the  meanings ascribed to such terms in the Merger Agreement.

       2. Grant of Option. Subject to the terms and conditions set forth herein,
Issuer hereby grants to Grantee an irrevocable option (the "Option") to purchase
up to 992,321  shares (as  adjusted as set forth  herein,  the "Option  Shares,"
which shall  include  the Option  Shares  before and after any  transfer of such
Option  Shares)  of common  stock,  $.01 par value  per  share  ("Issuer  Common
Stock"),  of Issuer at a purchase  price per Option Share (subject to adjustment
as set forth herein, the "Purchase Price") equal to $18.65;  provided,  however,
that in no event  shall the  number of shares of Issuer  Common  Stock for which
this Option is exercisable exceed the lesser of (i) 19.9% of the Issuer's issued
and  outstanding  shares of Issuer  Common Stock  without  giving  effect to any
shares subject to or issued  pursuant to the Option and (ii) that minimum number
of shares of Issuer Common Stock which when  aggregated with any other shares of
Issuer Common Stock beneficially owned by Grantee or any Affiliate thereof would
cause the provisions of any Takeover Laws of the Virginia Stock  Corporation Act
to be applicable to the Merger.

       3.     Exercise of Option.

              (a) Provided that (i) Grantee or Holder (as hereinafter  defined),
as  applicable,  shall not be in material  breach of its agreements or covenants
contained in this Agreement or the Merger Agreement,  and (ii) no preliminary or
permanent  injunction or other order  against the delivery of shares  covered by
the Option  issued by any court of competent  jurisdiction  in the United States
shall be in effect,  Holder may exercise the Option, in whole or in part, at any
time and from time to time  following  the  occurrence  of a Purchase  Event and
prior to the termination of the Option.  The Option shall terminate and be of no
further force and effect upon the earliest to occur of (A) the  Effective  Time,
(B)  termination  of the Merger  Agreement in accordance  with





the terms thereof prior to the  occurrence of a Purchase  Event or a Preliminary
Purchase  Event  (other than a  termination  of the Merger  Agreement by Grantee
pursuant to (i) Section  10.1(b)  thereof  (but only if such  termination  was a
result of a willful breach by Issuer) or (ii) Section  10.1(c) thereof (but only
if such termination was a result of a willful breach by Issuer) (each a "Default
Termination")),  (C) 12 months  after a Default  Termination,  and (D) 12 months
after any  termination  of the Merger  Agreement  following the  occurrence of a
Purchase  Event or a  Preliminary  Purchase  Event.  Any purchase of shares upon
exercise  of the Option  shall be subject to  compliance  with  applicable  law,
including,  without limitation, the Bank Holding Company Act of 1956, as amended
(the "BHC  Act").  The term  "Holder"  shall  mean the  holder or holders of the
Option from time to time,  and which  initially is the  Grantee.  The rights set
forth in  Section  8 shall  terminate  when the  right to  exercise  the  Option
terminates  (other than as a result of a complete exercise of the Option) as set
forth herein.

              (b) As used herein,  a "Purchase Event" means any of the following
events subsequent to the date of this Agreement:

                  (i) without Grantee's prior written consent, Issuer shall have
       authorized,  recommended,  publicly  proposed  or publicly  announced  an
       intention  to  authorize,  recommend  or  propose,  or  entered  into  an
       agreement  with any  person  (other  than  Grantee or any  Subsidiary  of
       Grantee) to effect an Acquisition Transaction (as defined below). As used
       herein,  the  term  Acquisition  Transaction  shall  mean  (A) a  merger,
       consolidation  or  similar  transaction  involving  Issuer  or any of its
       Subsidiaries   (other   than   transactions   solely   between   Issuer's
       Subsidiaries and transactions involving Issuer or any Subsidiary in which
       the voting  securities of Issuer  outstanding  immediately  prior thereto
       continue to represent (by either remaining outstanding or being converted
       into  securities of the surviving  entity or the parent thereof) at least
       75% of the combined  voting power of the voting  securities of the Issuer
       or the surviving  entity or the parent  thereof  outstanding  immediately
       after the  consummation  of the  transaction),  (B)  except as  permitted
       pursuant  to Section 7.1 of the Merger  Agreement,  the  disposition,  by
       sale,  lease,  exchange or  otherwise,  of Assets of Issuer or any of its
       Subsidiaries  representing in either case 25% or more of the consolidated
       assets of Issuer and its Subsidiaries, or (C) the issuance, sale or other
       disposition of (including by way of merger, consolidation, share exchange
       or any similar  transaction)  securities  representing 25% or more of the
       voting power of Issuer or any of its Subsidiaries  (any of the foregoing,
       an "Acquisition Transaction"); or

                  (ii) any  person  (other  than  Grantee or any  Subsidiary  of
       Grantee)  shall  have  acquired  beneficial  ownership  (as such  term is
       defined in Rule 13d-3  promulgated  under the Securities  Exchange Act of
       1934,  as  amended  (the  "Exchange  Act"),  of or the  right to  acquire
       beneficial  ownership  of, or any "group" (as such term is defined  under
       the  Exchange  Act),  other  than a group of which  Grantee or any of its
       Subsidiaries is a member,  shall have been formed which beneficially owns
       or has the right to acquire  beneficial  ownership of, 25% or more of the
       then-outstanding shares of Issuer Common Stock.

              (c) As used herein,  a "Preliminary  Purchase  Event" means any of
the following events:



                                      -2-


                  (i) any  person  (other  than  Grantee  or any  Subsidiary  of
       Grantee)  shall  have  commenced  (as such term is  defined in Rule 14d-2
       under the Exchange  Act),  or shall have filed a  registration  statement
       under the Securities Act of 1933, as amended (the "Securities  Act") with
       respect to, a tender  offer or exchange  offer to purchase  any shares of
       Issuer  Common Stock such that,  upon  consummation  of such offer,  such
       person would own or control 25% or more of the then-outstanding shares of
       Issuer Common Stock (such an offer being  referred to herein as a "Tender
       Offer" or an "Exchange Offer," respectively); or

                  (ii)  the  holders  of  Issuer  Common  Stock  shall  not have
       approved the Merger  Agreement at the meeting of such  shareholders  held
       for the purpose of voting on the Merger Agreement, such meeting shall not
       have been held or shall have been canceled  prior to  termination  of the
       Merger Agreement,  or Issuer's Board of Directors shall have withdrawn or
       modified in a manner  adverse to Grantee the  recommendation  of Issuer's
       Board of  Directors  with respect to the Merger  Agreement,  in each case
       after it shall have been publicly  announced  that any person (other than
       Grantee or any  Subsidiary of Grantee)  shall have (A) made a proposal to
       engage in an  Acquisition  Transaction,  (B)  commenced a Tender Offer or
       filed a registration  statement  under the Securities Act with respect to
       an  Exchange  Offer,  or (C) filed an  application  (or given a  notice),
       whether in draft or final  form,  under any  federal or state  statute or
       regulation (including a notice filed under the HSR Act and an application
       or notice  filed under the BHC Act, the Bank Merger Act, or the Change in
       Bank  Control  Act  of  1978)  seeking  the  Consent  to  an  Acquisition
       Transaction  from  any  federal  or  state   governmental  or  regulatory
       authority or agency.

As used in this Agreement, "person" shall have the meaning specified in Sections
3(a)(9) and 13(d)(3) of the Exchange Act.

              (d) In the event Holder  wishes to exercise  the Option,  it shall
send to Issuer a written  notice (the date of which being herein  referred to as
the "Notice  Date")  specifying (i) the total number of Option Shares it intends
to purchase pursuant to such exercise and (ii) a place and date not earlier than
five  business days nor later than 30 business days from the Notice Date for the
closing (the "Closing") of such purchase (the "Closing Date").  If prior Consent
of any governmental or regulatory  agency or authority is required in connection
with such  purchase,  Issuer  shall  cooperate  with Holder in the filing of the
required  notice or  application  for such  Consent  and the  obtaining  of such
Consent  and the  Closing  shall  occur  immediately  following  receipt of such
Consents (and expiration of any mandatory waiting periods).

       4.     Payment and Delivery of Certificates.

              (a) On each  Closing  Date,  Holder  shall (i) pay to  Issuer,  in
immediately  available  funds by wire  transfer to a bank account  designated by
Issuer, an amount equal to the Purchase Price multiplied by the number of Option
Shares to be purchased on such Closing Date, and (ii) present and surrender this
Agreement to the Issuer at the address of the Issuer  specified in Section 13(f)
hereof.


                                      -3-


              (b)  At  each  Closing,   simultaneously   with  the  delivery  of
immediately  available  funds and  surrender  of this  Agreement  as provided in
Section  4(a),  (i)  Issuer  shall  deliver  to  Holder  (A)  a  certificate  or
certificates  representing  the Option  Shares to be purchased at such  Closing,
which Option  Shares shall be free and clear of all liens,  claims,  charges and
encumbrances  of any kind whatsoever and subject to no pre-emptive  rights,  and
(B) if the Option is exercised in part only, an executed new agreement  with the
same terms as this Agreement evidencing the right to purchase the balance of the
shares of Issuer  Common  Stock  purchasable  hereunder,  and (ii) Holder  shall
deliver  to  Issuer a letter  agreeing  that  Holder  shall not offer to sell or
otherwise  dispose of such Option Shares in violation of applicable  federal and
state law or of the provisions of this Agreement.

              (c) In addition to any other legend that is required by applicable
law,  certificates  for the Option  Shares  delivered at each  Closing  shall be
endorsed with a restrictive legend which shall read substantially as follows:

       THE TRANSFER OF THE STOCK  REPRESENTED BY THIS  CERTIFICATE IS SUBJECT TO
       RESTRICTIONS  ARISING UNDER THE SECURITIES  ACT OF 1933, AS AMENDED,  AND
       PURSUANT TO THE TERMS OF A STOCK OPTION AGREEMENT DATED AS OF OCTOBER 28,
       1998.  A COPY OF SUCH  AGREEMENT  WILL BE PROVIDED  TO THE HOLDER  HEREOF
       WITHOUT CHARGE UPON RECEIPT BY THE ISSUER OF A WRITTEN REQUEST THEREFOR.

It is  understood  and agreed that:  (i) the  references  in the above legend to
resale  restrictions  of the  Securities  Act shall be  removed by  delivery  of
substitute  certificate(s) without such reference if Holder shall have delivered
to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel
in form and substance reasonably  satisfactory to Issuer and its counsel, to the
effect that such legend is not required for purposes of the Securities Act; (ii)
the references in the above legend to the provisions of this Agreement  shall be
removed by delivery of substitute  certificate(s)  without such reference if the
shares have been sold or transferred  in compliance  with the provisions of this
Agreement  and under  circumstances  that do not require the  retention  of such
reference;  and  (iii)  the  legend  shall be  removed  in its  entirety  if the
conditions in the preceding clauses (i) and (ii) are both satisfied.

       5. Representations and Warranties of Issuer. Issuer hereby represents and
warrants to Grantee as follows:

         (a) Issuer has all  requisite  corporate  power and  authority to enter
       into this Agreement and, subject to any approvals  referred to herein, to
       consummate  the  transactions  contemplated  hereby.  The  execution  and
       delivery  of this  Agreement  and the  consummation  of the  transactions
       contemplated  hereby have been duly authorized by all necessary corporate
       action on the part of Issuer.  This  Agreement has been duly executed and
       delivered by Issuer.

                                      -4-


         (b) Issuer has taken all  necessary  corporate  action to authorize and
       reserve and to permit it to issue, and, at all times from the date hereof
       until the  obligation to deliver Issuer Common Stock upon the exercise of
       the Option terminates,  will have reserved for issuance, upon exercise of
       the Option,  the number of shares of Issuer  Common Stock  necessary  for
       Holder to  exercise  the  Option,  and  Issuer  will  take all  necessary
       corporate  action to authorize  and reserve for  issuance all  additional
       shares of Issuer  Common  Stock or other  securities  which may be issued
       pursuant to Section 7 upon  exercise of the Option.  The shares of Issuer
       Common Stock to be issued upon due exercise of the Option,  including all
       additional shares of Issuer Common Stock or other securities which may be
       issuable pursuant to Section 7, upon issuance  pursuant hereto,  shall be
       duly and 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 Issuer.

       6.  Representations and Warranties of Grantee.  Grantee hereby represents
and warrants to Issuer that:

         (a) Grantee has all  requisite  corporate  power and authority to enter
       into this Agreement and, subject to any approvals or consents referred to
       herein, to consummate the transactions contemplated hereby. The execution
       and delivery of this Agreement and the  consummation of the  transactions
       contemplated  hereby have been duly authorized by all necessary corporate
       action on the part of Grantee.  This Agreement has been duly executed and
       delivered by Grantee.

         (b) This Option is not being, and any Option Shares or other securities
       acquired by Grantee  upon  exercise  of the Option will not be,  acquired
       with  a  view  to  the  public  distribution  thereof  and  will  not  be
       transferred or otherwise  disposed of except in a transaction  registered
       or exempt from registration under the Securities Laws.

       7.     Adjustment upon Changes in Capitalization, etc.

              (a) In the event of any change in Issuer Common Stock by reason of
a stock dividend, stock split, split-up, recapitalization, combination, exchange
of shares or similar  transaction,  the type and number of shares or  securities
subject to the  Option,  and the  Purchase  Price  therefor,  shall be  adjusted
appropriately,  and proper  provision shall be made in the agreements  governing
such  transaction,  if any, so that Holder shall  receive,  upon exercise of the
Option,  the number and class of shares or other  securities  or  property  that
Holder would have  received in respect of Issuer  Common Stock if the Option had
been exercised  immediately prior to such event, or the record date therefor, as
applicable. If any additional shares of Issuer Common Stock are issued after the
date of this Agreement  (other than pursuant to an event  described in the first
sentence of this Section 7(a) or pursuant to this Option),  the number of shares
of Issuer  Common Stock  subject to the Option shall be adjusted so that,  after
such issuance,  it,  together with any shares of Issuer Common Stock  previously
issued pursuant  hereto,  shall not exceed the lesser of (i) 19.9% of the number
of shares of Issuer  Common Stock then issued and  outstanding,  without  giving
effect to any shares  subject to or issued  pursuant to the

                                      -5-


Option and (ii) that minimum  number of shares of Issuer Common Stock which when
aggregated  with any other shares of Issuer Common Stock  beneficially  owned by
Grantee or any Affiliate thereof would cause the provisions of any Takeover Laws
of the Virginia Stock Corporation Act to be applicable to the Merger.

              (b) In the event that Issuer shall enter in an  agreement:  (i) to
consolidate  with or merge into any  person,  other  than  Grantee or one of its
Subsidiaries,  and shall not be the continuing or surviving  corporation of such
consolidation or merger; (ii) to permit any person, other than Grantee or one of
its  Subsidiaries,  to merge into Issuer and Issuer shall be the  continuing  or
surviving corporation, but, in connection with such merger, the then outstanding
shares of Issuer  Common Stock shall be changed  into or exchanged  for stock or
other  securities of Issuer or any other person or cash or any other property or
the outstanding  shares of Issuer Common Stock  immediately prior to such merger
shall after such merger  represent less than 50% of the  outstanding  shares and
share equivalents of the merged company;  or (iii) to sell or otherwise transfer
all or substantially all of its Assets to any person,  other than Grantee or one
of its Subsidiaries,  then, and in each such case, the agreement  governing such
transaction  shall make proper  provisions  so that the Option  shall,  upon the
consummation of any such transaction and upon the terms and conditions set forth
herein,  be  converted  into,  or  exchanged  for,  an option  (the  "Substitute
Option"),  at the election of Grantee,  of either (x) the Acquiring  Corporation
(as defined below) or (y) any person that controls the Acquiring Corporation (in
each case, such person being referred to as the "Substitute Option Issuer").

              (c) The Substitute Option shall have the same terms as the Option,
provided that, if the terms of the Substitute Option cannot,  for legal reasons,
be the same as the Option,  such terms shall be as similar as possible and in no
event less  advantageous  to Grantee.  The  Substitute  Option Issuer shall also
enter into an agreement with the then-holder or holders of the Substitute Option
in substantially  the same form as this Agreement,  which shall be applicable to
the Substitute Option.

              (d) The Substitute  Option shall be exercisable for such number of
shares of the Substitute  Common Stock (as  hereinafter  defined) as is equal to
the Assigned Value (as hereinafter  defined)  multiplied by the number of shares
of the Issuer  Common  Stock for which the Option was  theretofore  exercisable,
divided by the Average Price (as hereinafter defined). The exercise price of the
Substitute  Option per share of the  Substitute  Common  Stock (the  "Substitute
Purchase  Price")  shall then be equal to the  Purchase  Price  multiplied  by a
fraction  in which the  numerator  is the number of shares of the Issuer  Common
Stock for which the Option was  theretofore  exercisable  and the denominator is
the number of shares for which the Substitute Option is exercisable.

              (e) The following terms have the meanings indicated:

                  (i) "Acquiring  Corporation"  shall mean (x) the continuing or
       surviving  corporation of a consolidation or merger with Issuer (if other
       than Issuer), (y) Issuer in a merger in which Issuer is the continuing or
       surviving  person,  and (z) the transferee of all or any substantial part
       of the Issuer's assets (or the assets of its Subsidiaries).

                                      -6-


                  (ii)  "Substitute  Common  Stock"  shall mean the common stock
       issued by the  Substitute  Option Issuer upon exercise of the  Substitute
       Option.

                  (iii) "Assigned Value" shall mean the highest of (x) the price
       per share of the Issuer  Common Stock at which a Tender Offer or Exchange
       Offer therefor has been made by any person (other than Grantee),  (y) the
       price  per  share of the  Issuer  Common  Stock to be paid by any  person
       (other than the Grantee)  pursuant to an agreement  with Issuer,  and (z)
       the highest  last sale price per share of Issuer  Common  Stock quoted on
       the  Nasdaq  NMS (or if Issuer  Common  Stock is not quoted on the Nasdaq
       NMS,  the  highest  bid  price  per  share  on any day as  quoted  on the
       principal trading market or securities  exchange on which such shares are
       traded as reported by a recognized  source chosen by Grantee)  within the
       six-month period immediately preceding the agreement;  provided,  that in
       the event of a sale of less than all of  Issuer's  assets,  the  Assigned
       Value shall be the sum of the price paid in such sale for such assets and
       the current market value of the remaining  assets of Issuer as determined
       by a nationally  recognized  investment  banking firm selected by Grantee
       (or by a majority in interest of the Grantees if there shall be more than
       one Grantee (a "Grantee Majority")) and reasonably  acceptable to Issuer,
       divided by the number of shares of the Issuer Common Stock outstanding at
       the time of such sale.  In the event that an  exchange  offer is made for
       the Issuer  Common  Stock or an agreement is entered into for a merger or
       consolidation  involving  consideration other than cash, the value of the
       securities or other property  issuable or deliverable in exchange for the
       Issuer  Common  Stock  shall be  determined  by a  nationally  recognized
       investment banking firm selected by Grantee and reasonably  acceptable to
       Issuer (or if applicable, Acquiring Corporation). (If there shall be more
       than  one  Grantee,  any  such  selection  shall  be  made  by a  Grantee
       Majority.)

                  (iv) "Average Price" shall mean the average closing price of a
       share  of the  Substitute  Common  Stock  for  the one  year  immediately
       preceding the consolidation,  merger or sale in question, but in no event
       higher than the closing sale price of the shares of the Substitute Common
       Stock on the day preceding such  consolidation,  merger or sale; provided
       that if Issuer is the issuer of the Substitute  Option, the Average Price
       shall be  computed  with  respect  to a share of common  stock  issued by
       Issuer,  the person  merging into Issuer or by any company which controls
       or is controlled by such merger person, as Grantee may elect.

              (f) In no event pursuant to any of the foregoing  paragraphs shall
the Substitute Option be exercisable for more than 19.9% of the aggregate of the
shares of the  Substitute  Common  Stock  outstanding  prior to  exercise of the
Substitute  Option. In the event that the Substitute Option would be exercisable
for more than 19.9% of the  aggregate of the shares of  Substitute  Common Stock
but for this clause (f), the Substitute  Option Issuer shall make a cash payment
to Grantee equal to the excess of (i) the value of the Substitute Option without
giving  effect to the  limitation  in this clause (f) over (ii) the value of the
Substitute Option after giving effect to the limitation in this clause (f). This
difference in value shall be determined  by a nationally  recognized  investment
banking  firm  selected  by  Grantee  (or a  Grantee  Majority)  and  reasonably
acceptable to the Acquiring Corporation.

                                      -7-


              (g)  Issuer  shall not enter  into any  transaction  described  in
subsection (b) of this Section 7 unless the Acquiring Corporation and any person
that controls the Acquiring Corporation assume in writing all the obligations of
Issuer  hereunder  and take all other  actions that may be necessary so that the
provisions of this Section 7 are given full force and effect (including, without
limitation,  any action that may be necessary  so that the shares of  Substitute
Common Stock are in no way  distinguishable  from or have lesser  economic value
than other shares of common stock issued by the Substitute Option Issuer).

              (h) The provisions of Sections 8, 9, 10, and 11 shall apply,  with
appropriate  adjustments,  to  any  securities  for  which  the  Option  becomes
exercisable  pursuant to this Section 7 and, as  applicable,  references in such
sections to "Issuer," "Option," "Purchase Price" and "Issuer Common Stock" shall
be deemed to be references to "Substitute Option Issuer,"  "Substitute  Option,"
"Substitute Purchase Price" and "Substitute Common Stock," respectively.

       8.     Repurchase at the Option of Holder.

              (a) Subject to the last  sentence of Section  3(a), at the request
of Holder at any time commencing upon the first occurrence of a Repurchase Event
(as defined in Section 8(d)) and ending 12 months immediately thereafter, Issuer
shall  repurchase  from Holder the Option and all shares of Issuer  Common Stock
purchased  by Holder  pursuant  hereto  with  respect to which  Holder  then has
beneficial  ownership.  The date on which Holder exercises its rights under this
Section 8 is referred to as the "Request Date." Such  repurchase  shall be at an
aggregate price (the "Section 8 Repurchase Consideration") equal to the sum of:

                  (i) the aggregate Purchase Price paid by Holder for any shares
       of Issuer  Common  Stock  acquired by Holder  pursuant to the Option with
       respect to which Holder then has beneficial ownership;

                  (ii) the  excess,  if any,  of (x) the  Applicable  Price  (as
       defined  below)  for  each  share of  Issuer  Common  Stock  over (y) the
       Purchase Price (subject to adjustment  pursuant to Section 7), multiplied
       by the number of shares of Issuer  Common Stock with respect to which the
       Option has not been exercised; and

                  (iii) the  excess,  if any, of the  Applicable  Price over the
       Purchase Price (subject to adjustment pursuant to Section 7) paid (or, in
       the case of Option  Shares  with  respect  to which the  Option  has been
       exercised but the Closing Date has not  occurred,  payable) by Holder for
       each share of Issuer  Common  Stock with  respect to which the Option has
       been  exercised  and with  respect to which  Holder  then has  beneficial
       ownership, multiplied by the number of such shares.

              (b) If Holder  exercises  its rights  under this Section 8, Issuer
shall,  within ten  business  days after the  Request  Date,  pay the  Section 8
Repurchase   Consideration  to  Holder  in  immediately   available  funds,  and
contemporaneously  with such payment Holder shall surrender to Issuer the Option
and the  certificates  evidencing  the shares of Issuer  Common Stock  

                                      -8-


purchased thereunder with respect to which Holder then has beneficial ownership,
and Holder  shall  warrant that it has sole record and  beneficial  ownership of
such  shares  and that the same are then  free and clear of all  liens,  claims,
charges and encumbrances of any kind whatsoever.  Notwithstanding the foregoing,
to the extent  that prior  notification  to or  Consent of any  governmental  or
regulatory agency or authority is required in connection with the payment of all
or any portion of the Section 8 Repurchase Consideration,  Holder shall have the
ongoing  option to revoke its request for  repurchase  pursuant to Section 8, in
whole or in part,  or to  require  that  Issuer  deliver  from time to time that
portion  of the  Section  8  Repurchase  Consideration  that  it is not  then so
prohibited  from paying and promptly file the required notice or application for
Consent and expeditiously  process the same (and each party shall cooperate with
the other in the filing of any such notice or  application  and the obtaining of
any such  Consent).  If any  governmental  or  regulatory  agency  or  authority
disapproves of any part of Issuer's proposed repurchase pursuant to this Section
8, Issuer shall promptly give notice of such fact to Holder. If any governmental
or regulatory  agency or authority  prohibits the  repurchase in part but not in
whole, then Holder shall have the right (i) to revoke the repurchase  request or
(ii) to the extent permitted by such agency or authority,  determine whether the
repurchase should apply to the Option and/or Option Shares and to what extent to
each, and Holder shall thereupon have the right to exercise the Option as to the
number of Option Shares for which the Option was exercisable at the Request Date
less the sum of the  number of shares  covered by the Option in respect of which
payment  has been made  pursuant  to Section  8(a)(ii)  and the number of shares
covered by the portion of the Option (if any) that has been repurchased.  Holder
shall notify Issuer of its  determination  under the preceding  sentence  within
five business days of receipt of notice of disapproval of the repurchase.

                    Notwithstanding  anything  herein  to the  contrary,  all of
Holder's  rights under this Section 8 shall terminate on the date of termination
of this Option pursuant to Section 3(a).

              (c) For purposes of this Agreement,  the "Applicable  Price" means
the highest of (i) the highest  price per share of Issuer  Common Stock paid for
any such share by the person or groups  described in Section  8(d)(i),  (ii) the
price per share of Issuer  Common  Stock  received  by holders of Issuer  Common
Stock in connection  with any merger or other business  combination  transaction
described in Section 7(b)(i),  7(b)(ii) or 7(b)(iii),  or (iii) the highest last
sale  price per share of Issuer  Common  Stock  quoted on the  Nasdaq NMS (or if
Issuer  Common  Stock is not quoted on the Nasdaq NMS, the highest bid price per
share as quoted on the principal trading market or securities  exchange on which
such  shares are traded as  reported by a  recognized  source  chosen by Holder)
during the 60 business days preceding the Request Date; provided,  however, that
in the event of a sale of less than all of Issuer's Assets, the Applicable Price
shall be the sum of the price paid in such sale for such  assets and the current
market value of the remaining  assets of Issuer as determined by an  independent
nationally  recognized investment banking firm selected by Holder and reasonably
acceptable to Issuer (which  determination  shall be conclusive for all purposes
of this  Agreement),  divided by the number of shares of the Issuer Common Stock
outstanding at the time of such sale. If the  consideration to be offered,  paid
or  received  pursuant to either of the  foregoing  clauses (i) or (ii) shall be
other than in cash, the value of such consideration  shall be determined in good
faith by an independent  nationally  recognized 

                                      -9-


investment banking firm selected by Holder and reasonably  acceptable to Issuer,
which determination shall be conclusive for all purposes of this Agreement.

              (d) As used herein,  a  "Repurchase  Event" shall occur if (i) any
person  (other than Grantee or any  subsidiary  of Grantee  shall have  acquired
beneficial  ownership (as such term is defined in Rule 13d-3  promulgated  under
the Exchange Act), or the right to acquire beneficial ownership,  or any "group"
(as such term is defined  under the  Exchange  Act) shall have been formed which
beneficially  owns or has the right to acquire  beneficial  ownership  of 50% or
more of the  then-outstanding  shares of Issuer Common Stock, or (ii) any of the
transactions  described  in  Section  7(b)(i),  7(b)(ii),  or  7(iii)  shall  be
consummated.

       9.     Registration Rights.

              (a) Issuer shall,  subject to the conditions of  subparagraph  (c)
below,  if  requested  by  any  Holder,  including  Grantee  and  any  permitted
transferee  ("Selling Holder"),  as expeditiously as possible prepare and file a
registration statement under the Securities Laws if necessary in order to permit
the sale or other  disposition  of any or all shares of Issuer  Common  Stock or
other  securities  that have been acquired by or are issuable to Selling  Holder
upon  exercise of the Option in accordance  with the intended  method of sale or
other  disposition  stated by Holder in such  request (it being  understood  and
agreed  that any such sale or other  disposition  shall be  effected on a widely
distributed basis so that, upon consummation thereof, no purchaser or transferee
shall  beneficially  own more than 5% of the shares of Issuer  Common Stock then
outstanding),  including,  without limitation,  a "shelf" registration statement
under Rule 415 under the Securities Act or any successor  provision,  and Issuer
shall use its best efforts to qualify such shares or other  securities  for sale
under any applicable  state  securities laws. Each such Holder shall provide all
information  reasonably  requested by Issuer for  inclusion in any  registration
statement to be filed hereunder.

              (b) If Issuer at any time after the  exercise of the  Option,  but
prior to the  termination  of the Option,  proposes  to  register  any shares of
Issuer Common Stock under the Securities Laws in connection with an underwritten
public  offering of such Issuer Common Stock,  Issuer will promptly give written
notice to Holder of its  intention  to do so and,  upon the  written  request of
Holder  given  within 30 days after  receipt of any such notice  (which  request
shall  specify  the  number  of shares of Issuer  Common  Stock  intended  to be
included in such  underwritten  public offering by Selling Holder),  Issuer will
use all reasonable  efforts to cause all such shares, the holders of which shall
have  requested  participation  in such  registration,  to be so registered  and
included in such underwritten public offering;  provided,  that Issuer may elect
to not cause any such shares to be so registered (i) if the underwriters in good
faith  determine  that the  inclusion  of such shares would  interfere  with the
successful  marketing  of the shares of Issuer  Common  Stock for the account of
Issuer,  or (ii) in the case of a  registration  solely to  implement a dividend
reinvestment or similar plan, an employee  benefit plan or a registration  filed
on Form S-3, Form S-8, or any successor form, or a registration  filed on a form
which does not permit  registrations of resales;  provided,  further,  that such
election  pursuant to clause (i) may only be made twice. If some but not all the
shares of Issuer Common Stock,  with respect to which Issuer shall have received
requests for registration  pursuant to this  subparagraph (b), shall be excluded
from such 

                                      -10-


registration,   Issuer  shall  make  appropriate  allocation  of  shares  to  be
registered  among Selling Holders and any other person (other than Issuer or any
person   exercising   demand   registration   rights  in  connection  with  such
registration)  who or which is  permitted  to  register  their  shares of Issuer
Common Stock in connection  with such  registration  pro rata in the  proportion
that the number of shares  requested to be  registered  by each  Selling  Holder
bears to the total number of shares  requested to be  registered  by all persons
then desiring to have Issuer Common Stock registered for sale (other than Issuer
or any person  exercising  demand  registration  rights in connection  with such
registration).

              (c)  Issuer  shall  use  all  reasonable   efforts  to  cause  the
registration statement referred to in subparagraph (a) above to become effective
and to obtain  all  consents  or  waivers of other  parties  which are  required
therefor  and to keep such  registration  statement  effective,  provided,  that
Issuer  may delay  any  registration  of  Option  Shares  required  pursuant  to
subparagraph (a) above for a period not exceeding 90 days, provided Issuer shall
in good faith determine that any such  registration  would  adversely  affect an
offering or contemplated offering of other securities by Issuer. Notwithstanding
anything  to the  contrary  contained  herein,  Issuer  shall not be required to
register Option Shares under the Securities  Laws pursuant to  subparagraph  (a)
above:

                  (i)      prior  to  the  occurrence  of a  Purchase  Event and
       following  the  termination  of the Option;

                  (ii)     more than once;

                  (iii)   within  90  days  after  the   effective   date  of  a
       registration  referred to in subparagraph (b) above pursuant to which the
       Selling Holders  concerned were afforded the opportunity to register such
       shares  under the  Securities  Laws and such  shares were  registered  as
       requested; and

                  (iv)  unless a request  therefor  is made to Issuer by Selling
       Holders  holding at least 25% or more of the  aggregate  number of Option
       Shares  then  outstanding  or the  right to  acquire  at least 25% of the
       Option Shares.

                    In addition to the  foregoing,  Issuer shall not be required
to maintain the effectiveness of any registration statement after the expiration
of 120 days from the effective date of such registration statement. Issuer shall
use all reasonable  efforts to make any filings,  and take all steps,  under all
applicable  state  securities laws to the extent necessary to permit the sale or
other  disposition  of the Option Shares so  registered  in accordance  with the
intended method of distribution for such shares, provided, that Issuer shall not
be required to consent to general  jurisdiction or qualify to do business in any
state where it is not otherwise  required to so consent to such  jurisdiction or
to so qualify to do business.

              (d) Except where  applicable  state law prohibits  such  payments,
Issuer will pay all expenses  (including without  limitation  registration fees,
qualification  fees, blue sky fees and expenses (including the fees and expenses
of  Issuer's  counsel),  accounting  expenses,  printing  expenses,  expenses of
underwriters,  excluding  discounts  and  commissions  but  including  liability

                                      -11-


insurance  if  Issuer  so  desires  or the  underwriters  so  require,  and  the
reasonable  fees and expenses of any  necessary  special  experts) in connection
with each registration  pursuant to subparagraph (a) or (b) above (including the
related  offerings and sales by Selling  Holders) and all other  qualifications,
notifications  or  exemptions   pursuant  to  subparagraph  (a)  or  (b)  above.
Underwriting  discounts and commissions  relating to Option Shares and any other
expenses   incurred  by  such  Selling  Holders  in  connection  with  any  such
registration  (including expenses of Selling Holders' counsel) shall be borne by
such Selling Holders.

              (e) In connection with any registration  under subparagraph (a) or
(b) above  Issuer  hereby  agrees to  indemnify  the Selling  Holders,  and each
underwriter thereof,  including each person, if any, who controls such holder or
underwriter  within the meaning of Section 15 of the Securities Act, against all
expenses, losses, claims, damages and liabilities caused by any untrue statement
of a  material  fact  contained  in any  registration  statement  or  prospectus
(including any amendments or supplements thereto) or any preliminary prospectus,
or caused by any omission to state therein 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, except insofar as such
expenses,  losses,  claims, damages or liabilities of such indemnified party are
caused by any untrue  statement or alleged  untrue  statement or any omission or
alleged  omission  made in reliance  upon and in  conformity  with,  information
furnished  in  writing to Issuer by such  indemnified  party  expressly  for use
therein, and Issuer and each officer,  director and controlling person of Issuer
shall be indemnified by such Selling Holder, or by such underwriter, as the case
may be, for all such expenses, losses, claims, damages and liabilities caused by
any untrue, or alleged untrue,  statement or omission made in reliance upon, and
in conformity with, information furnished in writing to Issuer by such holder or
such underwriter, as the case may be, expressly for such use.

                    Promptly  upon  receipt  by a party  indemnified  under this
subparagraph  (e) of notice  of the  commencement  of any  action  against  such
indemnified  party in respect of which indemnity or reimbursement  may be sought
against any  indemnifying  party under this  subparagraph  (e), such indemnified
party shall notify the indemnifying party in writing of the commencement of such
action, but the failure so to notify the indemnifying party shall not relieve it
of any liability which it may otherwise have to any indemnified party under this
subparagraph  (e),  except to the  extent  such  failure  to  notify  materially
prejudices the  indemnifying  party.  In case notice of commencement of any such
action  shall  be  given  to the  indemnifying  party  as  above  provided,  the
indemnifying party shall be entitled to participate in and, to the extent it may
wish, jointly with any other indemnifying  party similarly  notified,  to assume
the defense of such action at its own  expense,  with  counsel  chosen by it and
reasonably  satisfactory to such indemnified  party. The indemnified party shall
have the right to employ separate  counsel in any such action and participate in
the  defense  thereof,  but the fees and  expenses of such  counsel  (other than
reasonable costs of investigation) shall be paid by the indemnified party unless
(i) the indemnifying  party either agrees to pay the same, (ii) the indemnifying
party fails to assume the defense of such action with  counsel  satisfactory  to
the  indemnified  party,  or (iii) the  indemnified  party has been  advised  by
counsel that one or more legal  defenses  may be  available to the  indemnifying
party that may be contrary to the interest of the  indemnified  party,  in which
case the  indemnifying  party  shall be  entitled  to assume the 

                                      -12-


defense of such action  notwithstanding its obligation to bear fees and expenses
of such counsel;  provided,  however,  that the indemnifying  party shall not be
liable for the  expenses  of more than one firm of counsel  for all  indemnified
parties  in any  jurisdiction.  No  indemnifying  party  shall be liable for any
settlement  entered  into  without  its  consent,   which  consent  may  not  be
unreasonably withheld.

                    If the indemnification provided for in this subparagraph (e)
is unavailable to a party otherwise entitled to be indemnified in respect of any
expenses,  losses,  claims,  damages or liabilities referred to herein, then the
indemnifying  party, in lieu of indemnifying such party otherwise entitled to be
indemnified,  shall contribute to the amount paid or payable by such party to be
indemnified as a result of such expenses, losses, claims, damages or liabilities
in such proportion as is appropriate to reflect the relative  benefits  received
by Issuer,  all Selling  Holders and the  underwriters  from the offering of the
securities  and also the relative fault of Issuer,  all Selling  Holders and the
underwriters  in connection  with the statements or omissions  which resulted in
such expenses,  losses,  claims,  damages or  liabilities,  as well as any other
relevant  equitable  considerations.  The amount paid or payable by a party as a
result of the expenses,  losses,  claims,  damages and  liabilities  referred to
above shall be deemed to include any legal or other fees or expenses  reasonably
incurred by such party in connection with  investigating or defending any action
or claim; provided, that in no case shall any Selling Holder be responsible,  in
the  aggregate,   for  any  amount  in  excess  of  the  net  offering  proceeds
attributable to its Option Shares included in the offering.  No person guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities  Act) shall be entitled to  contribution  from any person who was not
guilty of such  fraudulent  misrepresentation.  Any  obligation by any holder to
indemnify shall be several and not joint with other holders.

                    In connection with any registration pursuant to subparagraph
(a) or (b) above,  Issuer and each Selling  Holder  (other than  Grantee)  shall
enter  into an  agreement  containing  the  indemnification  provisions  of this
subparagraph (e).

              (f) Issuer shall use its best efforts to comply with all reporting
requirements and will do all such other things as may be necessary to permit the
expeditious  sale at any time of any Option Shares by Holder in accordance  with
and to the extent  permitted by any rule or  regulation  promulgated  by the SEC
from time to time, including, without limitation, Rules 144 and 144A.

              (g)  Issuer  will  pay all  stamp  taxes  in  connection  with the
issuance and the sale of the Option Shares and in  connection  with the exercise
of the Option,  and will save Holder  harmless,  without  limitation as to time,
against any and all liabilities, with respect to all such taxes.

       10. Quotation; Listing. If Issuer Common Stock or any other securities to
be acquired  upon  exercise of the Option are then  authorized  for quotation or
trading or listing on the  Nasdaq NMS or any other  securities  exchange  or any
automated  quotations  system  maintained  by  a  self-regulatory  organization,
Issuer,  upon the  request of Holder,  will  promptly  file an  application,  if
required,  to authorize for quotation or trading or listing the shares of Issuer
Common Stock or other  securities  acquired  upon  exercise of the Option on the
Nasdaq NMS or any other securities 

                                      -13-


exchange or any automated  quotations  system  maintained  by a  self-regulatory
organization and will use its best efforts to obtain approval,  if required,  of
such quotation or listing as soon as practicable.

       11.  Division of Option.  This Agreement (and the Option granted  hereby)
are exchangeable,  without expense,  at the option of Holder,  upon presentation
and  surrender  of this  Agreement at the  principal  office of Issuer for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase in the  aggregate the same number of shares of Issuer 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 Issuer 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, Issuer 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 Issuer, whether or not the
Agreement  so  lost,  stolen,  destroyed  or  mutilated  shall  at any  time  be
enforceable by anyone.

       12.    Miscellaneous.

              (a) Expenses.  Except as otherwise  provided in Section 9, 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) Waiver and  Amendment.  Any provision of this Agreement may be
waived  at any  time by the  party  that is  entitled  to the  benefits  of such
provision. This Agreement may not be modified,  amended, altered or supplemented
except upon the  execution and delivery of a written  agreement  executed by the
parties hereto.

              (c) Entire Agreement;  No Third-Party  Beneficiary;  Severability.
This Agreement,  together with the Merger  Agreement and the other documents and
instruments  referred  to herein and  therein,  between  Grantee  and Issuer (a)
constitutes  the  entire  agreement  and  supersedes  all prior  agreements  and
understandings,  both written and oral,  between the parties with respect to the
subject matter hereof,  except as provided in the Merger  Agreement,  and (b) is
not intended to confer upon any person other than the parties hereto (other than
any  transferees  of the  Option  Shares  or any  permitted  transferee  of this
Agreement  pursuant  to Section  12(h) and other than as  provided in the Merger
Agreement) any rights or remedies hereunder. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent  jurisdiction or a
federal or state  governmental or regulatory  agency or authority to be invalid,
void or  unenforceable,  the remainder of the terms,  provisions,  covenants and
restrictions  of this 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 does not permit Holder to acquire,
or does not require  Issuer to  repurchase,  the full number of shares of Issuer
Common  Stock as 

                                      -14-


provided  in  Sections 3 and 8 (as  adjusted  pursuant  to Section 7), it is the
express  intention of Issuer to allow Holder to acquire or to require  Issuer to
repurchase  such  lesser  number  of shares as may be  permissible  without  any
amendment or modification hereof.

              (d) Governing Law. This Agreement  shall be governed and construed
in accordance with the laws of the State of North Carolina without regard to any
applicable conflicts of law rules.

              (e)  Descriptive  Headings.  The  descriptive  headings  contained
herein are for convenience of reference only and shall not affect in any way the
meaning or interpretation of this Agreement.

              (f) Notices. All notices and other communications  hereunder shall
be in writing  and shall be deemed  given if  delivered  personally,  telecopied
(with  confirmation)  or mailed by registered or certified mail (return  receipt
requested) to the parties at the addresses set forth in the Merger  Agreement(or
at such other address for a party as shall be specified by like notice).

              (g) Counterparts.  This Agreement and any amendments hereto may be
executed in two counterparts, each of which shall be considered one and the same
agreement and shall become effective when both counterparts have been signed, it
being understood that both parties need not sign the same counterpart.

              (h)  Assignment.  Neither  this  Agreement  nor any of the rights,
interests or obligations  hereunder or under the Option shall be assigned by any
of the parties  hereto  (whether by operation of law or  otherwise)  without the
prior  written  consent of the other party,  except that Grantee may assign this
Agreement  to a wholly  owned  Subsidiary  of Grantee and Grantee may assign its
rights  hereunder in whole or in part after the occurrence of a Purchase  Event;
provided, however, that Grantee may not assign its rights under the Option until
the date 15 days following the date of approval of an application to acquire the
shares by the appropriate  federal  regulatory  authorities,  except in a widely
disbursed  public  distribution.  Grantee will pay any  reasonable  costs of the
Issuer  in  connection  with  any  such  assignment.  Subject  to the  preceding
sentence,  this Agreement shall be binding upon,  inure to the benefit of and be
enforceable by the parties and their respective successors and assigns.

              (i) Further Assurances. In the event of any exercise of the Option
by Holder,  Issuer and Holder shall execute and deliver all other  documents and
instruments and take all other action that may be reasonably  necessary in order
to consummate the transactions provided for by such exercise.

              (j)  Specific  Performance.  The  parties  hereto  agree that this
Agreement  may  be  enforced  by  either  party  through  specific  performance,
injunctive  relief and other  equitable  relief.  Both parties  further agree to
waive any requirement for the securing or posting of any bond in connection with
the obtaining of any such  equitable  relief and that this  provision is without
prejudice to any other  rights that the parties  hereto may have for any failure
to perform this Agreement.

                                      -15-


       IN WITNESS  WHEREOF,  Issuer and Grantee  have  caused this Stock  Option
Agreement to be signed by their respective  officers  thereunto duly authorized,
all as of the day and year first written above.
