                             STOCK OPTION AGREEMENT

   THIS STOCK OPTION AGREEMENT (this "Agreement") is made and entered into as
of November 7, 2001, by and between MID-AMERICA BANCORP, a Kentucky corporation
("MAB" or "Issuer"), and BB&T CORPORATION, a North Carolina corporation
("Grantee").

                                R E C I T A L S:

   WHEREAS, Grantee and Issuer have entered into that certain Agreement and
Plan of Reorganization, dated this date (the "Merger Agreement"), providing
for, among other things, the merger of Issuer with and into Grantee; 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 to 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 2,200,000 shares (as adjusted as set forth herein, the "Option
Shares," which term shall refer to the Option Shares before and after any
transfer of such Option Shares), of the common stock of Issuer, no par value
("Issuer Common Stock"), at a purchase price per Option Share (subject to
adjustment as set forth herein, the "Purchase Price") equal to $25.75.

   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 (as
hereinafter defined); provided, that the Option shall terminate and be of no
further force and effect upon the earliest to occur of (A) the Effective Time,
(B) subject to clause (E) below, termination of the Merger Agreement in
accordance with the terms thereof prior to the occurrence of a Purchase Event
or a Preliminary Purchase Event (as hereinafter defined) (other than a
termination of the Merger Agreement by Grantee pursuant to Section 7.1(b)
thereof (a "Default Termination")), (C) 12 months after a Default Termination,
(D) 12 months after any termination of the Merger Agreement (other than a
Default Termination) following the occurrence of a Purchase Event or a
Preliminary Purchase Event, and (E) subject to clause (D) above, 12 months
after termination of the Merger Agreement pursuant to Section 7.1(e) thereof;
provided further, that 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"). Subject to
compliance with Section 12(h) hereof, the term "Holder" shall mean the holder
or holders of the Option from time to time, including initially Grantee. The
rights set forth in Section 8 hereof 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.


                                       1


    (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 or between Issuer's
  Subsidiaries and Issuer), (B) the disposition, by sale, lease, exchange or
  otherwise, of assets of Issuer or any of its Subsidiaries representing in
  either case 15% or more of the consolidated assets of Issuer and its
  Subsidiaries (other than a sale of loan receivables in a financing
  transaction in the normal course of business consistent with past
  practices), or (C) the issuance, sale or other disposition (including by
  way of merger, consolidation, share exchange or any similar transaction) of
  securities representing 15% or more of the voting power of Issuer or any of
  its Subsidiaries; 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 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 the
  Subsidiaries of Grantee is a member, shall have been formed which
  beneficially owns or has the right to acquire beneficial ownership of, 15%
  or more of the then-outstanding shares of Issuer Common Stock. For purposes
  of the preceding sentence, the beneficial ownership of more than 15% of the
  outstanding shares of Issuer Common Stock by Bertram W. Klein, as described
  in Issuer's definitive proxy statement on Schedule 14A dated March 27,
  2001, shall not constitute a purchase event.

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

       (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 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 15% 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 any person (other than
  Grantee or any Subsidiary of Grantee) shall have (A) made, or disclosed an
  intention to make, 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 an application or notice
  filed under the BHC Act, the Bank Merger Act, the Home Owners' Loan 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) Notwithstanding the foregoing, the obligation of MAB to issue Option
Shares upon exercise of the Option shall be deferred (but shall not terminate):
(i) until the receipt of all required governmental or regulatory approvals or
consents necessary for MAB to issue the Option Shares or Holder to exercise the
Option, or until

                                       2


the expiration or termination of any waiting period required by law, or (ii) so
long as any injunction or other order, decree or ruling issued by any federal
or state court of competent jurisdiction is in effect which prohibits the sale
or delivery of the Option Shares.

    (e) 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
three business days nor later than 15 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 at Holder's expense, and the Closing shall occur not earlier than
three business days nor later than 15 business days 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 referenced in Section
12(f) hereof.

    (b) At each Closing, simultaneously with the delivery of immediately
available funds and surrender of this Agreement as provided in Section 4(a)
hereof, (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 preemptive 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 evidencing Holder's agreement not to offer, 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 NOVEMBER 7,
  2001. 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 the above legend shall be removed by delivery
of substitute certificate(s) without such legend if Holder shall have delivered
to Issuer a copy of a letter from the staff of the Commission, 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.

   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 its obtaining 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 Issuer. This Agreement has been duly executed and delivered by
Issuer.


                                       3


    (b) Issuer has taken all necessary corporate and other 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 hereof
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
hereof, 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 its obtaining 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) Grantee represents that it is acquiring the Option for Grantee's own
account and not with a view to, or for sale in connection with, any
distribution of the Option or the Option Shares. Grantee represents that it is
aware that neither the Option nor the Option Shares is the subject of a
registration statement filed with and declared effective by the Commission
pursuant to Section 5 of the Securities Act, but instead each is being offered
in reliance upon the exemption from the registration requirement provided by
Section 4(2) thereof and the representations and warranties made by Grantee in
connection therewith. Grantee represents that neither the Option nor the
Option Shares will be transferred or otherwise disposed of except in a
transaction registered or exempt from registration under the Securities Laws,
and that with respect to any transfer or other disposition proposed to be made
in reliance upon an exemption from registration, such transfer or other
disposition shall not be made unless MAB first receives an opinion of counsel
in form and substance reasonably acceptable to it regarding the availability
of such exemption.

   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 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)), the number of shares of Issuer Common
Stock subject to the Option shall be adjusted so that, after such issuance,
it, when added to the number of shares of Issuer Common Stock previously
issued pursuant hereto, equals 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 Option.

    (b) In the event that Issuer shall enter into an agreement (prior to
termination of the Option pursuant to Section 3(a) hereof): (i) to consolidate
with or merge into any person, other than Grantee or one of its Subsidiaries,
and Issuer 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

                                       4


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; (iii) to permit any person, other than
Grantee or one of its Subsidiaries, to acquire all of the outstanding shares of
Issuer Common Stock pursuant to a statutory share exchange; or (iv) 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, deemed granted by either
(x) the Acquiring Corporation (as defined below), (y) any person that controls
the Acquiring Corporation, or (z) in the case of a merger described in clause
(ii), the Issuer (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
identical to those of 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
agreement 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 the continuing or surviving
  corporation of a consolidation or merger with Issuer (if other than
  Issuer), Issuer in a merger in which Issuer is the continuing or surviving
  person, the corporation that shall acquire all of the outstanding shares of
  Issuer Common Stock pursuant to a statutory share exchange, or the
  transferee of all or substantially all of the Issuer's assets (or the
  assets of its Subsidiaries).

        (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
  closing sales price per share of Issuer Common Stock quoted on the American
  Stock Exchange (the "AMEX") 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")), 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 mutually selected by Grantee and Issuer (or if
  applicable, Acquiring Corporation). (If there shall be more than one
  Grantee, any such selection shall be made by a Grantee Majority.)


                                       5


       (iv) "Average Price" shall mean the average closing price of a share
  of the Substitute Common Stock for the one-year period immediately
  preceding effectiveness of the consolidation, merger, share exchange or
  sale in question, but in no event higher than the closing price of the
  shares of the Substitute Common Stock on the day preceding the
  effectiveness of such consolidation, merger, share exchange 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 sections 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).

    (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 hereof 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) hereof, 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.


                                       6


    (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 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 the consent or approval 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 approval 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 approval), in which case the ten business day
period of time that would otherwise run pursuant to the preceding sentence for
the payment of the portion of the Section 8 Repurchase Consideration shall run
instead from the date on which, as the case may be, any required notification
period has expired or been terminated or such approval has been obtained and,
in either event, any requisite waiting period shall have passed. 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) hereof.

    (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) hereof, (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 Sections 7(b)(i), 7(b)(ii), 7(b)(iii) or 7(b)(iv) hereof, or (iii)
the highest closing sales price per share of Issuer Common Stock quoted on the
AMEX (or if Issuer Common Stock is not quoted on the AMEX, 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 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, "Repurchase Event" shall occur if (i) any person (other
than Grantee or any Subsidiary of Grantee) or "group" (within the meaning of
the Exchange Act) shall have acquired beneficial

                                       7


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),
7(b)(iii) or 7(b)(iv) shall be consummated.

   9. Registration Rights.

    (a) For a period of 24 months following termination of the Merger
Agreement, Issuer shall, subject to the conditions of subsection (c) below, if
requested by any Holder, including Grantee and any permitted transferee of the
Option Shares ("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 the Selling Holder in such request,
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.

    (b) If Issuer at any time after the exercise 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 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 cause any such shares not to be so registered (i) if the underwriters in
good faith object for a valid business reason, 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-4 or any successor
form, or a registration filed on a form which does not permit registration of
resales; provided, further, that such election pursuant to clause (i) may be
made only one time. 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 subsection (b), shall be excluded from such 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.

    (c) Issuer shall use all reasonable efforts to cause each registration
statement referred to in subsection (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 subsection (a) above for a
period not exceeding 90 days in the event that Issuer shall in good faith
determine that any such registration would adversely affect an offering or
contemplated offering of other securities by Issuer, and Issuer shall not be
required to register Option Shares under the Securities Laws pursuant to
subsection (a) above:

          (i)   prior to the occurrence of a Purchase Event;

          (ii)  on more than two occasions;

          (iii) more than once during any calendar year;

          (iv)  within 90 days after the effective date of a registration
    referred to in subsection (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

                                       8


        (v) 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.

     In addition to the foregoing, Issuer shall not be required to maintain
  the effectiveness of any registration statement after the expiration of
  nine months 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 counsel),
accounting expenses, legal expenses, including reasonable fees and expenses of
one counsel to the Selling Holders whose Option Shares are being registered,
printing expenses, reasonable expenses of underwriters, excluding discounts and
commissions but including liability 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 subsection
(a) or (b) above (including the related offerings and sales by Selling Holders)
and all other qualifications, notifications or exemptions pursuant to
subsection (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 shall be borne by such Selling Holders.

    (e) In connection with any registration under subsection (a) or (b) above
Issuer hereby indemnifies 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 or notification or
offering circular (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
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 omission or alleged omission that was included by
Issuer in any such registration statement or prospectus or notification or
offering circular (including any amendments or supplements thereto) 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 or alleged omission that was included by Issuer in any
such registration statement or prospectus or notification or offering circular
(including any amendments or supplements thereto) 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 subsection (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 subsection (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
subsection (e). 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 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 agrees to pay them, (ii) the indemnifying party fails to
assume the defense of such action

                                       9


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 any such case, the indemnifying party shall remain
entitled to assume the defense of such action notwithstanding its obligation to
bear fees and expenses of the indemnified party's counsel. 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 subsection (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 subsection (a) or (b) above,
Issuer and each Selling Holder (other than Grantee) shall enter into an
agreement containing the indemnification provisions of this subsection (e).

    (f) Issuer shall 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 the Selling Holders in accordance with and to the
extent permitted by any rule or regulation promulgated by the Commission from
time to time, including, without limitation, Rules 144 and 144A. Issuer shall
at its expense provide the Selling Holders with any information necessary in
connection with the completion and filing of any reports or forms required to
be filed by them under the Securities Laws, or required pursuant to any state
securities laws or the rules of any stock exchange.

    (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, upon the occurrence of a Purchase
Event, authorized for quotation or trading or listing on the AMEX or any other
securities exchange or any automated quotations system maintained by a self-
regulatory organization, Issuer will promptly file an application, if required,
to authorize for quotation or trading or listing the shares of Issuer Common
Stock or other securities to be acquired upon exercise of the Option on the
AMEX or any other securities 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) is
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

                                       10


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, 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) 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 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) hereof) 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 provided, in Sections 3 and 8 hereof (as adjusted pursuant to
Section 7 hereof), 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 by and construed and
enforced in accordance with the laws of the State of North Carolina without
regard to any applicable conflicts of law rules, except to the extent that the
federal laws of the United States shall govern.

    (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; Transfer. Neither this Agreement nor any of the rights,
interests or obligations hereunder or under the Option shall be assigned or
transferred by any of the parties hereto (whether by

                                       11


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 or transfer its rights hereunder
in whole or in part after the occurrence of a Purchase Event. In the case of
any permitted assignment or transfer of the Option, Issuer shall do all things
necessary to facilitate the same, and the Holder to whom the Option is assigned
or transferred shall make the representations contained in Section 6 hereof
(with Holder substituted for Grantee) and shall agree in writing to the terms
and conditions hereof. 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.
