  be exchanged for each share of BankFirst Common Stock and for each share of
  BankFirst Preferred Stock issued and outstanding as of the Effective Time, and
  cash (without interest) to be payable in exchange for any fractional share of
  BB&T Common Stock which would otherwise be distributable to a BankFirst
  shareholder as provided in Section 2.7(b).

                                       6

   The portion of a share of BB&T Common Stock to be issued for each issued and
  outstanding share of BankFirst Common Stock (the "Common Exchange Ratio")
  shall be .4554. The number of shares of BB&T Common Stock to be issued for
  each issued and outstanding share of BankFirst Preferred Stock (the "Preferred
  Exchange Ratio") shall equal 1.4060.

     (b) The amount of cash payable with respect to any fractional share of BB&T
  Common Stock shall be determined by multiplying the fractional part of such
  share by the Closing Value. The "Closing Value" shall mean the average 4:00
  p.m. eastern time closing price per share of BB&T Common Stock on the NYSE on
  the Closing Date as reported on NYSEnet.com.

   2.8 Conversion of Shares; Payment of Merger Consideration

     (a) At the Effective Time, by virtue of the Merger and without any action
  on the part of BankFirst or the holders of record of BankFirst Common Stock or
  BankFirst Preferred Stock, each share of BankFirst Common Stock and each share
  of BankFirst Preferred Stock issued and outstanding immediately prior to the
  Effective Time shall be converted into and shall represent the right to
  receive, upon surrender of the certificate representing such share of
  BankFirst Common Stock or BankFirst Preferred Stock (as provided in subsection
  (d) below), the Merger Consideration.

     (b) Each share of BB&T Common Stock issued and outstanding immediately
  prior to the Effective Time shall continue to be issued and outstanding.

     (c) Until surrendered, each outstanding certificate which prior to the
  Effective Time represented one or more shares of BankFirst Common Stock or
  BankFirst Preferred Stock shall be deemed upon the Effective Time for all
  purposes to represent only the right to receive the Merger Consideration and
  any declared and unpaid dividends (with respect to BankFirst Common Stock) or
  accrued and unpaid dividends (with respect to BankFirst Preferred Stock). No
  interest will be paid or accrued on the Merger Consideration upon the
  surrender of the certificate or certificates representing shares of BankFirst
  Common Stock or BankFirst Preferred Stock. With respect to any certificate for
  BankFirst Common Stock or BankFirst Preferred Stock that has been lost or
  destroyed, BB&T shall pay the Merger Consideration attributable to such
  certificate upon receipt of a surety bond or other adequate indemnity as
  required in accordance with BB&T's standard policy, and evidence reasonably
  satisfactory to BB&T of ownership of the shares represented thereby. After the
  Effective Time, BankFirst's transfer books shall be closed and no transfer of
  the shares of BankFirst Common Stock or BankFirst Preferred Stock outstanding
  immediately prior to the Effective Time shall be made on the stock transfer
  books of the Surviving Corporation.

     (d) Promptly after the Effective Time, BB&T shall cause to be delivered or
  mailed to each BankFirst shareholder a form of letter of transmittal and
  instructions for use in effecting the surrender of the certificates which,
  immediately prior to the Effective Time, represented any shares of BankFirst
  Common Stock or BankFirst Preferred Stock. Upon proper surrender of such
  certificates or other evidence of ownership meeting the requirements of
  Section 2.8(c), together with such letter of transmittal duly executed and
  completed in accordance with the instructions thereto, and such other
  documents as may be reasonably requested, BB&T shall promptly cause the
  transfer to the persons entitled thereto of the Merger Consideration and any
  declared and unpaid dividends (with respect to BankFirst Common Stock) or
  accrued and unpaid dividends (with respect to BankFirst Preferred Stock).

     (e) The Surviving Corporation shall pay any dividends or other
  distributions with a record date prior to the Effective Time which have been
  declared or made by BankFirst in respect of shares of BankFirst Common Stock
  in accordance with the terms of this Agreement and which remain unpaid at the
  Effective Time, subject to compliance by BankFirst with Section 5.9(b). At the
  time of the Closing and incident thereto, BankFirst shall pay a per share
  dividend in respect of shares of BankFirst Preferred Stock equal to the
  product of $.0625 times a fraction, the numerator of which is the number of
  days following the payment date of the BankFirst Preferred Stock dividend
  preceding the Closing Date and the denominator of which is 91. Such payment
  shall constitute the sole right of the holders of the BankFirst Preferred
  Stock

                                       7
<PAGE>

  to a dividend with respect to such BankFirst Preferred Stock. To the extent
  permitted by law, former shareholders of record of BankFirst shall be entitled
  to vote after the Effective Time at any meeting of BB&T shareholders the
  number of whole shares of BB&T Common Stock into which their respective shares
  of BankFirst Common Stock or BankFirst Preferred Stock are converted,
  regardless of whether such holders have exchanged their certificates
  representing BankFirst Common Stock or BankFirst Preferred Stock for
  certificates representing BB&T Common Stock in accordance with the provisions
  of this Agreement. Whenever a dividend or other distribution is declared by
  BB&T on the BB&T Common Stock, the record date for which is at or after the
  Effective Time, the declaration shall include dividends or other distributions
  on all shares of BB&T Common Stock issuable pursuant to this Agreement, but no
  dividend or other distribution payable to the holders of record of BB&T Common
  Stock as of any time subsequent to the Effective Time shall be delivered to
  the holder of any certificate representing BankFirst Common Stock or BankFirst
  Preferred Stock until such holder surrenders such certificate for exchange as
  provided in this Section 2.8. Upon surrender of such certificate, both the
  BB&T Common Stock certificate and any undelivered dividends and cash payments
  payable hereunder (without interest) shall be delivered and paid with respect
  to the shares of BankFirst Common Stock or BankFirst Preferred Stock
  represented by such certificate.

   2.9 Conversion of Stock Options

     (a) At the Effective Time, each Stock Option then outstanding (and which by
  its terms does not lapse on or before the Effective Time), whether or not then
  exercisable, shall be converted into and become rights with respect to BB&T
  Common Stock, and BB&T shall assume each Stock Option in accordance with the
  terms of the Stock Option Plans, except that from and after the Effective Time
  (i) BB&T and its Compensation Committee shall be substituted for BankFirst and
  the Committee of BankFirst's Board of Directors administering the Stock Option
  Plans, (ii) each Stock Option assumed by BB&T may be exercised solely for
  shares of BB&T Common Stock, (iii) the number of shares of BB&T Common Stock
  subject to each such Stock Option shall be the number of whole shares of BB&T
  (omitting any fractional share) determined by multiplying the number of shares
  of BankFirst Common Stock subject to such Stock Option immediately prior to
  the Effective Time by the Common Exchange Ratio, and (iv) the per share
  exercise price under each such Stock Option shall be adjusted by dividing the
  per share exercise price under each such Stock Option by the Common Exchange
  Ratio and rounding up to the nearest cent. Notwithstanding the foregoing, BB&T
  may at its election substitute as of the Effective Time options under the BB&T
  Corporation 1995 Omnibus Stock Incentive Plan or any other duly adopted
  comparable plan (in either case, the "BB&T Option Plan") for all or a part of
  the Stock Options, subject to the following conditions: (A) the requirements
  of (iii) and (iv) above shall be met; (B) such substitution shall not
  constitute a modification, extension or renewal of any of the Stock Options;
  and (C) the substituted options shall continue in effect on the same terms and
  conditions as provided in the agreement manifesting each Stock Option and the
  Stock Option Plans governing each Stock Option. Each grant of a converted or
  substitute option to any individual who subsequent to the Merger will be a
  director or officer of BB&T as construed under Commission Rule 16b-3 shall be
  approved in accordance with the provisions of Commission Rule 16b-3. Each
  Stock Option which is an incentive stock option shall be adjusted as required
  by Section 424 of the Code, and the Regulations promulgated thereunder, so as
  to continue as an incentive stock option under Section 424(a) of the Code, and
  so as not to constitute a modification, extension, or renewal of the option
  within the meaning of Section 424(h) of the Code. BB&T and BankFirst agree to
  take all necessary steps to effectuate the foregoing provisions of this
  Section 2.9. BB&T has reserved and shall continue to reserve adequate shares
  duly registered with the Commission, of BB&T Common Stock for delivery upon
  exercise of any converted or substitute options. As soon as practicable after
  the Effective Time, if it has not already done so, and to the extent BankFirst
  shall have a registration statement in effect or an obligation to file a
  registration statement, BB&T shall file a registration statement on Form S-3
  or Form S- 8, as the case may be (or any successor or other appropriate
  forms), with respect to the shares of BB&T Common Stock subject to converted
  or substitute options and shall use its reasonable efforts to maintain the
  effectiveness of such registration statement (and maintain

                                       8
<PAGE>

  the current status of the prospectus or prospectuses contained therein) for so
  long as such converted or substitute options remain outstanding. With respect
  to those individuals, if any, who subsequent to the Merger may be subject to
  the reporting requirements under Section 16(a) of the Exchange Act, BB&T shall
  administer the Stock Option Plans assumed pursuant to this Section 2.9 (or the
  BB&T Option Plan, if applicable) in a manner that complies with Rule 16b-3
  promulgated under the Exchange Act to the extent necessary to preserve for
  such individuals the benefits of Rule 16b-3 to the extent such benefits were
  available to them prior to the Effective Time. BankFirst hereby represents
  that the Stock Option Plans in their current forms comply with Rule 16b-3 to
  the extent, if any, required as of the date hereof.

     (b) As soon as practicable following the Effective Time, BB&T shall deliver
  to the participants receiving converted options under the BB&T Option Plan an
  appropriate notice setting forth such participant's rights pursuant thereto.

     (c) Eligibility to receive stock option grants following the Effective Time
  with respect to BB&T Common Stock shall be determined by BB&T in accordance
  with its plans and procedures as in effect from time to time, and subject to
  any contractual obligations.

   2.10 Merger of Subsidiaries

   In the event that BB&T shall request, BankFirst shall take such actions, and
shall cause the BankFirst Subsidiaries to take such actions, as may be required
in order to effect, at the Effective Time, the merger of one or more of the
BankFirst Subsidiaries with and into, in each case, one of the BB&T
Subsidiaries.

   2.11 Anti-Dilution

   In the event BB&T changes the number of shares of BB&T Common Stock issued
and outstanding prior to the Effective Time as a result of a stock split, stock
dividend or other similar recapitalization, and the record date thereof (in the
case of a stock dividend) or the effective date thereof (in the case of a stock
split or similar recapitalization for which a record date is not established)
shall be prior to the Effective Time, the Common Exchange Ratio and the
Preferred Exchange Ratio shall be proportionately adjusted.

   2.12 Dissenting Shares.

   Any holder of shares of BankFirst Preferred Stock who shall have properly
exercised rights to dissent with respect to the Merger and to demand payment of
the "fair value" of the shareholder's shares (the "Dissenting Shares") in
accordance with Sections 48-23-101 et seq. of the TBCA (the "Dissenting
Shareholder") shall thereafter have only such rights, if any, as provided to a
dissenting shareholder under Sections 48-23-101 et seq. of the TCBA and shall
have no rights to receive the Merger Consideration under Sections 2.7 and 2.8;
provided, however, that (i) nothing contained herein shall limit such Dissenting
Shareholder's rights to the payment of all accrued and unpaid dividends as of
the Effective Time; and (ii) if a Dissenting Shareholder shall withdraw (in
accordance with the TCBA) the demand for such appraisal, shall fail to perfect
such demand as required under Section 48-23-202 of the TBCA or shall become
ineligible for such appraisal, then such Dissenting Shareholder's Dissenting
Shares automatically shall cease to be Dissenting Shares and shall be converted
into and represent only the right to receive from the Surviving Corporation,
upon surrender of the certificates representing the Dissenting Shares, the
Merger Consideration provided for in Section 2.7 and accrued and unpaid
dividends as provided in Section 2.8(c) and Section 2.8(e).

                                       14
<PAGE>

    purposes of this Agreement, the term "Plan" shall mean a plan, arrangement,
    agreement or program described in the foregoing provisions of this Section
    3.14(b)(i) and which is: (A) a profit-sharing, deferred compensation, bonus,
    stock option, stock purchase, pension, retainer, consulting, retirement,
    severance, welfare or incentive plan, agreement or arrangement, whether or
    not funded and whether or not terminated, (B) an employment agreement, (C) a
    material personnel policy or fringe benefit plan, policy, program or
    arrangement providing for benefits or perquisites to current or former
    employees, officers, directors or agents, whether or not funded, and whether
    or not terminated, including, without limitation, benefits relating to
    automobiles, clubs, vacation, child care, parenting, sabbatical, sick leave,
    severance, medical, dental, hospitalization, life insurance and other types
    of insurance, or (D) any other employee benefit plan as defined in Section
    3(3) of ERISA, whether or not funded and whether or not terminated.

       (ii) Neither BankFirst nor any BankFirst Subsidiary contributes to, has
    an obligation to contribute to or otherwise has any liability or potential
    liability with respect to (A) any multiemployer plan as defined in Section
    3(37) of ERISA, (B) any plan of the type described in Sections 4063 and 4064
    of ERISA or in Section 413 of the Code (and regulations promulgated
    thereunder), or (C) any plan which provides health, life insurance, accident
    or other "welfare-type" benefits to current or future retirees or former
    employees or directors, their spouses or dependents, other than in
    accordance with Section 4980B of the Code or applicable state continuation
    coverage law.

       (iii) None of the Plans obligates BankFirst or any BankFirst Subsidiary
    to pay separation, severance, termination or similar-type benefits solely as
    a result of any transaction contemplated by this Agreement or solely as a
    result of a "change in control," as such term is used in Section 280G of the
    Code (and regulations promulgated thereunder).

       (iv) Each Plan, and all related trusts, insurance contracts and funds,
    has been maintained, funded and administered in compliance in all respects
    with its own terms and in compliance in all respects with all applicable
    laws and regulations, including but not limited to ERISA and the Code. No
    actions, suits, claims, complaints, charges, proceedings, hearings,
    examinations, investigations, audits or demands with respect to the Plans
    (other than routine claims for benefits) are pending or threatened, and
    there are no facts which could give rise to or be expected to give rise to
    any actions, suits, claims, complaints, charges, proceedings, hearings,
    examinations, investigations, audits or demands. No Plan that is subject to
    the funding requirements of Section 412 of the Code or Section 302 of ERISA
    has incurred any "accumulated funding deficiency" as such term is defined in
    such Sections of ERISA and the Code, whether or not waived, and each Plan
    has always fully met the funding standards required under Title I of ERISA
    and Section 412 of the Code. No liability to the Pension Benefit Guaranty
    Corporation ("PBGC") (except for routine payment of premiums) has been or is
    expected to be incurred with respect to any Plan that is subject to Title IV
    of ERISA, no reportable event (as such term is defined in Section 4043 of
    ERISA) for which the PBGC has not waived notice has occurred with respect to
    any such Plan, and the PBGC has not commenced or threatened the termination
    of any Plan. None of the assets of BankFirst or any BankFirst Subsidiary is
    the subject of any lien arising under Section 302(f) of ERISA or Section
    412(n) of the Code, neither BankFirst nor any BankFirst Subsidiary has been
    required to post any security pursuant to Section 307 of ERISA or Section
    401(a)(29) of the Code, and there are no facts which could be expected to
    give rise to such lien or such posting of security. No event has occurred
    and no condition exists that would subject BankFirst or any BankFirst
    Subsidiary to any tax under Sections 4971, 4972, 4976, 4977 or 4979 of the
    Code or to a fine or penalty under Section 502(c) of ERISA.

       (v) Each Plan that is intended to be qualified under Section 401(a) of
    the Code, and each trust (if any) forming a part thereof, has received a
    favorable determination letter from the IRS as to the form of such Plan and
    its related trust, and nothing has occurred since the date of such
    determination letter that could adversely affect the qualification of such
    Plan or the tax exempt status of such related trust.

                                       15
<PAGE>

       (vi) No underfunded "defined benefit plan" (as such term is defined in
    Section 3(35) of ERISA) has been, during the five years preceding the
    Closing Date, transferred out of the controlled group of corporations
    (within the meaning of Sections 414(b), (c), (m) and (o) of the Code) of
    which BankFirst or any BankFirst Subsidiary is a member or was a member
    during such five-year period.

       (vii) As of December 31, 1999, the fair market value of the assets of
    each Plan that is a tax qualified defined benefit plan equaled or exceeded,
    and as of the Closing Date will equal or exceed, the present value of all
    vested and nonvested liabilities thereunder determined on an ongoing basis
    in accordance with reasonable actuarial methods, factors and assumptions
    applicable to a defined benefit plan. With respect to each Plan that is
    subject to the funding requirements of Section 412 of the Code and Section
    302 of ERISA, all required contributions for all periods ending prior to or
    as of the Closing Date (including periods from the first day of the
    then-current plan year to the Closing Date and including all quarterly
    contributions required in accordance with Section 412(m) of the Code) shall
    have been made. With respect to each other Plan, all required payments,
    premiums, contributions, reimbursements or accruals for all periods ending
    prior to or as of the Closing Date shall have been made. No tax qualified
    Plan has any unfunded liabilities.

       (viii) No prohibited transaction (which shall mean any transaction
    prohibited by Section 406 of ERISA and not exempt under Section 408 of ERISA
    or Section 4975 of the Code, whether by statutory, class or individual
    exemption) has occurred with respect to any Plan which would result in the
    imposition, directly or indirectly, of any excise tax, penalty or other
    liability under Section 4975 of the Code or Section 409 or 502(i) of ERISA.
    Neither BankFirst nor, to the Knowledge of BankFirst, any BankFirst
    Subsidiary, any trustee, administrator or other fiduciary of any Plan, or
    any agent of any of the foregoing has engaged in any transaction or acted or
    failed to act in a manner that could subject BankFirst or any BankFirst
    Subsidiary to any liability for breach of fiduciary duty under ERISA or any
    other applicable law.

       (ix) With respect to each Plan, all reports and information required to
    be filed with any government agency or distributed to Plan participants and
    their beneficiaries have been duly and timely filed or distributed.

       (x) BankFirst and each BankFirst Subsidiary has been and is presently in
    compliance with all of the requirements of Section 4980B of the Code.

       (xi) Neither BankFirst nor any BankFirst Subsidiary has a liability as of
    December 31, 1999 under any Plan that, to the extent disclosure is required
    under GAAP, is not reflected on the consolidated balance sheet included in
    the Financial Statements of BankFirst as of December 31, 1999 or otherwise
    Disclosed.

       (xii) Neither the consideration nor implementation of the transactions
    contemplated under this Agreement will increase (A) BankFirst's or any
    BankFirst Subsidiary's obligation to make contributions or any other
    payments to fund benefits accrued under the Plans as of the date of this
    Agreement or (B) the benefits accrued or payable with respect to any
    participant under the Plans (except to the extent benefits may be deemed
    increased by accelerated vesting, accelerated allocation of previously
    unallocated Plan assets or by the conversion of all stock options in
    accordance with Section 2.9.

       (xiii) With respect to each Plan, BankFirst has Disclosed or made
    available to BB&T, true, complete and correct copies of (A) all documents
    pursuant to which the Plans are maintained, funded and administered,
    including summary plan descriptions, (B) the three most recent annual
    reports (Form 5500 series) filed with the IRS (with attachments), (C) the
    three most recent actuarial reports, if any, (D) the three most recent
    financial statements, (E) all governmental filings for the last three years,
    including, without limitation, excise tax returns and reportable events
    filings, and (F) all governmental rulings, determinations, and opinions (and
    pending requests for governmental rulings, determinations, and opinions)
    during the past three years.

<PAGE>

       (xiv) Each of the Plans as applied to BankFirst and any BankFirst
    Subsidiary may be amended or terminated at any time by action of BankFirst's
    Board of Directors, or such BankFirst's Subsidiary's Board of Directors, as
    the case may be, or a committee of such Board of Directors or duly
    authorized officer, in each case subject to the terms of the Plan and
    compliance with applicable laws and regulations (and limited, in the case of
    multiemployer plans, to termination of the participation of BankFirst or a
    BankFirst Subsidiary thereunder).

   3.15 Certain Contracts

     (a) Neither BankFirst nor any BankFirst Subsidiary is a party to, is bound
  or affected by, or receives benefits under (i) any agreement, arrangement or
  commitment, written or oral, the default of which would have a Material
  Adverse Effect, whether or not made in the ordinary course of business (other
  than loans or loan commitments made or certificates or deposits received in
  the ordinary course of the banking business), or any agreement restricting its
  business activities, including, without limitation, agreements or memoranda of
  understanding with regulatory authorities, (ii) any agreement, indenture or
  other instrument, written or oral, relating to the borrowing of money by
  BankFirst or any BankFirst Subsidiary or the guarantee by BankFirst or any

  Subsidiary (without payment of any penalty or cost, except with respect to
  Federal Home Loan Bank or Federal Reserve Bank advances), (iii) any agreement,
  arrangement or commitment, written or oral, relating to the employment of a
  consultant, independent contractor or agent, or the employment, election or

  be terminated within less than 60 days after the Closing Date by BankFirst or
  any BankFirst Subsidiary (without payment of any penalty or cost), or that
  provides benefits which are contingent, or the application of which is
  altered, upon the occurrence of a transaction involving BankFirst of the
  nature contemplated by this Agreement or the BB&T Option Agreement, or (iv)
  any agreement or plan, written or oral, including any Stock Option Plans,
  stock appreciation rights plan, restricted stock plan or stock purchase plan,
  any of the benefits of which will be increased, or the vesting of the benefits
  of which will be accelerated, by the occurrence of any of the transactions
  contemplated by this Agreement or the BB&T Option Agreement or the value of
  any of the benefits of which will be calculated on the basis of any of the
  transactions contemplated by this Agreement or the BB&T Option Agreement. Each

  agreement, commitment, arrangement, lease, insurance policy, or other
  instrument, whether entered into in the ordinary course of business or

  that, with the lapse of time or giving of notice or both, would constitute
  such a default.

proceedings instituted, pending or, to the Knowledge of BankFirst, threatened

Plan or right of BankFirst or any BankFirst Subsidiary, or, to the Knowledge of
BankFirst, against any officer, director or employee of any of them in their
capacity as such. There are no actions, suits or proceedings instituted, pending

relating to BankFirst or any BankFirst Subsidiary exists (including, without
limitation, noncompliance with the CRA) that would prevent BankFirst or BB&T

anti-takeover laws, and no such law shall be activated or applied as a result of

impede or delay receipt of any consents of regulatory authorities referred to in
Section 5.4(b) or result in failure of the condition in Section 6.3(b);
provided, that nothing that nothing contained herein shall limit the ability of
BB&T to exercise its rights under the BB&T Option Agreement,

   4.8 Share Ownership

capacity) any shares of BankFirst Common Stock.

   5.1 BankFirst Shareholder Meeting

   BankFirst shall submit this Agreement and the Plan of Merger to its
shareholders for approval at a meeting to be held as soon as reasonably
practicable following the date of effectiveness of the Registration Statement,
and by approving and authorizing the execution of this Agreement, the Board of
Directors of BankFirst agrees that it shall, at the time the Proxy
Statement/Prospectus is mailed to the shareholders of BankFirst, recommend that
BankFirst's shareholders vote for such approval; provided, that the Board of
Directors of BankFirst may withdraw, modify or refuse to make such
recommendation only if the Board of Directors shall determine in good faith that
such recommendation should not be made in light of its fiduciary duty to
BankFirst's shareholders after consideration of written advice of legal counsel
that, in the opinion of such counsel, such recommendation or the failure to
withdraw or modify such recommendation could reasonably be expected to
constitute a breach of the fiduciary duty of the Board of Directors to the
shareholders of BankFirst. Notwithstanding any other provisions hereof, by his
signature to this Agreement each member of the Board of Directors of BankFirst
hereby agrees that he will vote all issued and outstanding shares of voting
capital stock of BankFirst over which he has voting rights in favor of the Plan
of Merger, and will otherwise support approval of the Plan of Merger by
shareholders of BankFirst, and that he will not, prior to the record date for
any vote on the Plan of Merger, convey or otherwise dispose of the right to vote
any such shares.

   5.2 Registration Statement; Proxy Statement/Prospectus

   As promptly as practicable after the date hereof, BB&T shall prepare and file
the Registration Statement with the Commission. BankFirst will furnish to BB&T
the information required to be included in the Registration Statement with
respect to its business and affairs before it is filed with the Commission and
again before any amendments are filed, and shall have the right to review and
consult with BB&T on the form of, and any characterizations of such information
included in, the Registration Statement prior to the filing with the Commission.
Such Registration Statement, at the time it becomes effective and on the
Effective Time, shall in all material respects conform to the requirements of
the Securities Act and the applicable rules and regulations of the Commission.
The Registration Statement shall include the form of Proxy Statement/Prospectus.
BB&T and BankFirst shall use all reasonable efforts to cause the Proxy
Statement/Prospectus to be approved by the Commission for mailing to the
BankFirst shareholders, and such Proxy Statement/Prospectus shall, on the date
of mailing, conform in all material respects to the requirements of the
Securities Laws and the applicable rules and regulations of the Commission
thereunder. BankFirst shall cause the Proxy Statement/Prospectus to be mailed to
shareholders in accordance with all applicable notice requirements under the
Securities Laws, the TBCA and the rules and regulations of the NYSE.

   5.3 Plan of Merger; Reservation of Shares

   At the Effective Time, the Merger shall be effected in accordance with the
Plan of Merger. In connection therewith, BB&T acknowledges that it (i) has
adopted the Plan of Merger and (ii) will pay or cause to be paid when due the
Merger Consideration. BB&T has reserved for issuance such number of shares of
BB&T Common Stock as shall be necessary to pay the Merger Consideration and
agrees not to take any action that would cause the aggregate number of
authorized shares of BB&T Common Stock available for issuance hereunder not to
be sufficient to effect the Merger. If at any time the aggregate number of
shares of BB&T Common Stock reserved for issuance hereunder is not sufficient to
effect the Merger, BB&T shall take all appropriate action as may be required to
increase the number of shares of BB&T Common Stock reserved for such purpose.

   5.4 Additional Acts

     (a) BankFirst agrees to take such actions requested by BB&T as may be
  reasonably necessary to modify the structure of, or to substitute parties to
  (so long as such substitute is BB&T or a BB&T Subsidiary) the transactions
  contemplated hereby, provided that such modifications do not change the Merger
  Consideration or abrogate the covenants and other agreements contained in this
  Agreement, including, without limitation, the covenant not to take any action
  that would substantially delay or impair the prospects of completing the
  Merger pursuant to this Agreement and the Plan of Merger.

     (b) As promptly as practicable after the date hereof, BB&T and BankFirst
  shall submit notice or applications for prior approval of the transactions
  contemplated herein to the Federal Reserve Board and any other federal, state
  or local government agency, department or body to which notice is required or
  from which approval is required for consummation of the Merger and the other
  transactions contemplated hereby. BankFirst and BB&T each represents and
  warrants to the other that all information included (or submitted for

  respective directors, officers and shareholders, shall be true, correct and
  complete in all material respects as of the date presented.

   5.5 Best Efforts

   Each of BB&T and BankFirst shall use, and shall cause each of their
respective Subsidiaries to use, its best efforts in good faith to (i) furnish
such information as may be required in connection with and otherwise cooperate
in the preparation and filing of the documents referred to in Sections 5.2 and
5.4 or elsewhere herein, and (ii) take or cause to be taken all action necessary
or desirable on its part to fulfill the conditions in Article VI, including,
without limitation, executing and delivering, or causing to be executed and
delivered, such representations, certificates and other instruments or documents
as may be reasonably requested by BB&T's legal counsel for such counsel to issue
the opinion contemplated by Section 6.1(e), and to consummate the transactions
herein contemplated at the earliest possible date. Neither BB&T nor BankFirst
shall take, or cause, or to the best of its ability permit to be taken, any
action that would substantially delay or impair the prospects of completing the
Merger pursuant to this Agreement and the Plan of Merger.

   5.6 Certain Accounting Matters

   BankFirst shall cooperate with BB&T concerning (i) accounting and financial
matters necessary or appropriate to facilitate the Merger (taking into account
BB&T's policies, practices and procedures), including, without limitation,
issues arising in connection with record keeping, loan classification, valuation
adjustments, levels of loan loss reserves and other accounting practices, and
(ii) BankFirst's lending, investment or asset/liability management policies;
provided, that any action taken pursuant to this Section 5.6 shall not be deemed
to constitute or result in the breach of any representation or warranty of
BankFirst contained in this Agreement; provided, however, that BankFirst shall
not be required to alter, amend, modify or change any such policies or practices
until the earlier of (i) such time as BB&T acknowledges to BankFirst or its
legal counsel that all conditions to its obligation to consummate the Merger
have been waived or satisfied (other than the delivery of certificates, opinions
and other instruments and documents to be delivered at Closing or otherwise to
be dated at the Effective Time, the delivery of which shall continue to be a
condition to BB&T's obligation to consummate the Merger) or (ii) immediately
prior to the Effective Time.

   5.7 Access to Information

   BankFirst and BB&T will each keep the other advised of all material
developments relevant to its business and the businesses of its Subsidiaries and
to consummation of the Merger, and each shall provide to the other, upon
request, reasonable details of any such development. Upon reasonable notice,
BankFirst shall afford to representatives of BB&T access, during normal business
hours during the period prior to the Effective Time, to all of the properties,
books, contracts, commitments and records of BankFirst and the BankFirst
Subsidiaries and, during such period, shall make available all information
concerning their businesses as may be reasonably

                                       23
<PAGE>

requested. No investigation pursuant to this Section 5.7 shall affect or be
deemed to modify any representation or warranty made by, or the conditions to
the obligations hereunder of, either party hereto. Each party hereto shall, and
shall cause each of its directors, officers, attorneys and advisors to, maintain
the confidentiality of all information obtained hereunder which is not otherwise
publicly disclosed by the other party, said undertakings with respect to
confidentiality to survive any termination of this Agreement pursuant to Section
7.1. In the event of the termination of this Agreement, each party shall return
to the other party upon request all confidential information previously
furnished in connection with the transactions contemplated by this Agreement.

   5.8 Press Releases

   BB&T and BankFirst shall agree with each other as to the form and substance
of any press release related to this Agreement and the Plan of Merger or the
transactions contemplated hereby and thereby, and consult with each other as to
the form and substance of other public disclosures related thereto; provided,
that nothing contained herein shall prohibit either party, following
notification to the other party, from making any disclosure which in the opinion
of its counsel is required by law.

   5.9 Forebearances of BankFirst

   Except with the prior written consent of BB&T, between the date hereof and

  practices; provided, however, that in no event shall Rights to purchase more
  than 100,000 shares of the capital stock of BankFirst (subject to adjustment
  as may be necessary for organic changes, if any) be granted between the date
  hereof and the Effective Time;

     (e) amend its Charter or Bylaws;

  Code as determined by BB&T, (ii) result in any inaccuracy of a representation
  or warranty herein which would allow for a termination of this Agreement, or
  (iii) cause any of the conditions precedent to the transactions contemplated
  by this Agreement to fail to be satisfied;

     (r) dispose of any material assets other than in the ordinary course of
  business; or

   5.10 Employment Agreements

   BB&T (or its specified BB&T Subsidiary) agrees to enter into employment
agreements with Fred R. Lawson, substantially in the form of Annex B hereto,
with R. Stephen Hagood substantially in the form of Annex C hereto, and with
Jerry L. French, C. David Allen, David M. Butler, Michael L. Bryson and L.Allen
Rathbone substantially in the form of Annex D hereto.

   5.11 Affiliates

   BankFirst shall use its best efforts to cause all persons who are Affiliates
of BankFirst to deliver to BB&T promptly following execution of this Agreement a
written agreement providing that such person will not dispose of BB&T Common
Stock received in the Merger, except in compliance with the Securities Act and
the rules and regulations promulgated thereunder, and in any event shall use its
best efforts to cause such affiliates to deliver to BB&T such written agreement
prior to the Closing Date.

   5.12 Section 401(k) Plan; Other Employee Benefits

     (a) Effective on the Benefit Plan Determination Date with respect to the
  401(k) plan of BankFirst, BB&T shall cause such plan to be merged with the
  401(k) plan maintained by BB&T and the BB&T Subsidiaries, or to be frozen or
  to be terminated, in each case as determined by BB&T and subject to the
  receipt of all applicable regulatory or governmental approvals. Each employee
  of BankFirst at the Effective Time (i) who is a participant in the 401(k) plan
  of BankFirst, (ii) who becomes an employee immediately following the Effective
  Time of BB&T or of any subsidiary of BB&T ("Employer Entity"), and (iii) who
  continues in the employment of an Employer Entity until the Benefit Plan
  Determination Date, shall be eligible to participate in BB&T's 401(k) plan as
  of the Benefit Plan Determination Date. Any other former employee of BankFirst
  who is employed by an Employer Entity on or after the Benefit Plan
  Determination Date shall be eligible to be a participant in the BB&T 401(k)
  plan upon complying with eligibility requirements. All rights to participate
  in BB&T's 401(k) plan are subject to BB&T's right to amend or terminate the
  plan. Until the Benefit Plan Determination Date, BB&T shall continue in effect
  for the benefit of participating employees the Section 401(k) plan of
  BankFirst. For purposes of administering BB&T's 401(k) plan, service with
  BankFirst and the BankFirst Subsidiaries shall be deemed to be service with
  BB&T for participation and vesting purposes, but not for purposes of benefit
  accrual. Each employee of BankFirst or a BankFirst Subsidiary at the Effective
  Time who becomes an employee immediately following the Effective Time of an
  Employer Entity is referred to herein as a "Transferred Employee".

     (b) Each Transferred Employee shall be eligible to participate in group
  hospitalization, medical, dental, life, disability and other welfare benefit
  plans and programs available to employees of the Employer Entity, subject to
  the terms of such plans and programs, as of the Benefit Plan Determination
  Date with respect to each such plan or program, conditional upon the
  Transferred Employee's being employed by an Employer Entity as of such Benefit
  Plan Determination Date and subject to complying

                                       26
<PAGE>

  with eligibility requirements of the respective plans and programs. BB&T's
  plans shall recognize and give credit under such BB&T plans to each
  Transferred Employee for any payments made by such Transferred Employee of
  deductible amounts and for payments made by such Transferred Employee
  applicable to out-of-pocket maximum obligations under the BankFirst Plans.
  With respect to health care coverages, participation in BB&T's plans may be
  subject to availability of HMO options. In any case in which HMO coverage is
  not available, substitute coverage will be provided which may not be fully
  comparable to the HMO coverage. With respect to any welfare benefit plan or
  program of BankFirst which the Employer Entity determines, in its sole
  discretion, provides benefits of the same type or class as a corresponding
  plan or program maintained by the Employer Entity, the Employer Entity shall
  continue such BankFirst plan or program in effect for the benefit of the
  Transferred Employees so long as they remain eligible to participate and until
  they shall become eligible to become participants in the corresponding plan or
  program maintained by the Employer Entity (and, with respect to any such plan
  or program, subject to complying with eligibility requirements and subject to
  the right of the Employer Entity to terminate such plan or program). For
  purposes of administering the welfare plans and programs subject to this
  Section 5.12(b), service with BankFirst shall be deemed to be service with the
  Employer Entity for the purpose of determining eligibility to participate and
  vesting (if applicable) in such welfare plans and programs, but not for the
  purpose of computing benefits, if any, determined in whole or in part with
  reference to service (except as otherwise provided in (c) below).

     (c) Except to the extent of commitments herein or other contractual
  commitments, if any, specifically made or assumed hereunder by BB&T, neither
  BB&T nor any Employer Entity shall have any obligation arising from the Merger
  to continue any Transferred Employees in its employ or in any specific job or
  to provide to any Transferred Employee any specified level of compensation or
  any incentive payments, benefits or perquisites. Each Transferred Employee who
  is terminated by an Employer Entity subsequent to the Effective Time,
  excluding any employee who has a then existing contract providing for
  severance, shall be entitled to severance pay in accordance with the general
  severance policy maintained by BB&T, if and to the extent that such employee
  is entitled to severance pay under such policy. Such employee's service with
  BankFirst or a BankFirst Subsidiary shall be treated as service with BB&T for
  purposes of determining the amount of severance pay, if any, under BB&T's
  severance policy.

     (d) BB&T agrees to honor all employment agreements, severance agreements
  and deferred compensation agreements that BankFirst and the BankFirst
  Subsidiaries have with their current and former employees and directors and
  which have been Disclosed to BB&T pursuant to this Agreement, except to the
  extent any such agreements shall be superseded or terminated at the Closing or
  following the Closing Date. Except for the agreements described in the
  preceding sentence and except as otherwise provided in this Section 5.12, the
  employee benefit plans of BankFirst shall, in the sole discretion of BB&T, be
  frozen, terminated or merged into comparable plans of BB&T, effective as BB&T
  shall determine in its sole discretion.

   5.13 Directors and Officers Protection

   BB&T or a BB&T Subsidiary shall provide and keep in force for a period of
three years after the Effective Time directors' and officers' liability
insurance providing coverage to directors and officers of BankFirst for acts or
omissions occurring prior to the Effective Time. Such insurance shall provide at
least the same coverage and amounts as contained in BankFirst's policy on the
date hereof; provided, that in no event shall the annual premium on such policy
exceed 150% of the annual premium payments on BankFirst's policy in effect as of
the date hereof (the "Maximum Amount"). If the amount of the premiums necessary
to maintain or procure such insurance coverage exceeds the Maximum Amount, BB&T
shall use its reasonable efforts to maintain the most advantageous policies of
directors' and officers' liability insurance obtainable for a premium equal to
the Maximum Amount. Notwithstanding the foregoing, BB&T further agrees to
indemnify all individuals who are or have been officers, directors or employees
of BankFirst or any BankFirst Subsidiary prior to the Effective Time from any
acts or omissions in such capacities prior to the Effective Time, to the extent
that such indemnification is provided pursuant to the Charter or Bylaws of
BankFirst on the date hereof and is permitted under the NCBCA to the fullest
lawful extent.

   5.14 Forbearances of BB&T

   Except with the prior written consent of BankFirst, which consent shall not
be arbitrarily or unreasonably withheld, between the date hereof and the
Effective Time neither BB&T nor any BB&T Subsidiary shall take any action which
would or might be expected to (i) cause the business combination contemplated
hereby not to constitute a reorganization under Section 368 of the Code; (ii)
result in any inaccuracy of a representation or warranty herein which would
allow for termination of this Agreement; (iii) cause any of the conditions
precedent to the transactions contemplated by this Agreement to fail to be
satisfied; (iv) exercise the BB&T Option Agreement other than in accordance with
its terms, or dispose of the shares of BankFirst Common Stock issuable upon
exercise of the option rights conferred thereby other than as permitted by the
terms thereof; or (v) fail to comply in any material respect with any laws,
regulations, ordinances or governmental actions applicable to it and to the
conduct of its business.

   5.15 Reports

   Each of BankFirst and BB&T shall file (and shall cause the BankFirst
Subsidiaries and the BB&T Subsidiaries, respectively, to file), between the date
of this Agreement and the Effective Time, all reports required to be filed by it
with the Commission and any other regulatory authorities having jurisdiction
over such party, and shall deliver to BB&T or BankFirst, as the case may be,
copies of all such reports promptly after the same are filed. If financial
statements are contained in any such reports filed with the Commission, such
financial statements will fairly present the consolidated financial position of
the entity filing such statements as of the dates indicated and the consolidated
results of operations, changes in shareholders' equity, and cash flows for the
periods then ended in accordance with GAAP (subject in the case of interim
financial statements to the absence of notes and to normal recurring year-end
adjustments that are not material). As of their respective dates, such reports
filed with the Commission will comply in all material respects with the
Securities Laws and will not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. Any financial statements contained in any other
reports to a regulatory authority other than the Commission shall be prepared in
accordance with requirements applicable to such reports.

   5.16 Exchange Listing

   BB&T shall use its reasonable best efforts to list, prior to the Effective
Time, on the NYSE, subject to official notice of issuance, the shares of BB&T
Common Stock to be issued to the holders of BankFirst Common Stock pursuant to
the Merger, and BB&T shall give all notices and make all filings with the NYSE
required in connection with the transactions contemplated herein.

   5.17 Advisory Boards

   As of the Effective Time, BB&T shall offer to the members of the Board of
Directors of BankFirst a seat on the BB&T Advisory Board for the BB&T Community
Bank region based in Knoxville, Tennessee. For two years following the Effective
Time, the Advisory Board members appointed pursuant to this Section 5.17 and who
continue to serve shall receive, as compensation for service on the Advisory
Board, Advisory Board member's fees (annual retainer and attendance fees) equal
in amount each year (prorated for any partial year) to the annual retainer and
schedule of attendance fees for directors of BankFirst in effect on August 1,
2000. Following such two-year period, Advisory Board Members, if they continue
to serve in such capacity, shall receive fees in accordance with BB&T's standard
schedule of fees for service thereon as in effect from time to time. For two
years after the Effective Time, no such Advisory Board member shall be
prohibited from serving thereon because he or she shall have attained the
maximum age for service thereon (currently age 70). Membership of any person on
any Advisory Board shall be conditional upon execution of an agreement providing
that such person will not engage in activities competitive with BB&T for two
years following the Effective Time or, if longer, the period that he or she is a
member of the Advisory Board.

   As of the Effective Time, Branch Banking and Trust Company, a North Carolina
banking corporation, shall elect James L. Clayton to its Board of Directors, to
serve until its next annual meeting (subject to the right of removal for cause)
and thereafter so long as he is elected and qualifies. Any member of such Board
of Directors who is not an employee of BB&T or any of its Affiliates shall be
entitled to receive fees for service on the Board in accordance with BB&T's
policies as in effect from time to time.

   7.1 Termination

   This Agreement may be terminated:

     (a) At any time prior to the Effective Time, by the mutual consent in
  writing of the parties hereto.

     (b) At any time prior to the Effective Time, by either party (i) in the
  event of a material breach by the other party of any covenant or agreement
  contained in this Agreement, or (ii) in the event of an inaccuracy of any
  representation or warranty of the other party contained in this Agreement,
  which inaccuracy would provide the nonbreaching party the ability to refuse to
  consummate the Merger under the applicable standard set forth in Section
  6.2(a) in the case of BankFirst and Section 6.3(a) in the case of BB&T; and,
  in the case of (i) or (ii), if such breach or inaccuracy has not been cured by
  the earlier of thirty days following written notice of such breach to the
  party committing such breach or the Effective Time.

     (c) At any time prior to the Effective Time, by either party hereto in
  writing, if any of the conditions precedent to the obligations of the other
  party to consummate the transactions contemplated hereby cannot be satisfied
  or fulfilled prior to the Closing Date, and the party giving the notice is not
  in material breach of any of its representations, warranties, covenants or
  undertakings herein.

     (d) At any time, by either party hereto in writing, if any of the
  applications for prior approval referred to in Section 5.4 are denied, and the
  time period for appeals and requests for reconsideration has run.

     (e) At any time, by either party hereto in writing, if the shareholders of
  BankFirst do not approve the Agreement and the Plan of Merger.

     (f) At any time following March 31, 2001 by either party hereto in writing,
  if the Effective Time has not occurred by the close of business on such date,
  and the party giving the notice is not in material breach of any of its
  representations, warranties, covenants or undertakings herein.

     (g) At any time, by either party hereto in writing, if an order, decree or
  injunction is imposed by a court or agency of competent jurisdiction which
  enjoins or prohibits consummation of the transactions contemplated by this
  Agreement, after commercially reasonable steps have been taken by the parties
  hereto to have such order, decree or injunction vacated, reversed or removed
  but such order, decree or injunction is not successfully vacated, reversed or
  removed and becomes non-appealable and final.

   7.2 Effect of Termination

   In the event this Agreement and the Plan of Merger is terminated pursuant to
Section 7.1, both this Agreement and the Plan of Merger shall become void and
have no effect, except that (i) the provisions hereof

<PAGE>

relating to confidentiality and expenses set forth in Sections 5.7 and 8.1,
respectively, shall survive any such termination and (ii) a termination pursuant

breach of the covenant, agreement, representation or warranty giving rise to
such termination. The BB&T Option Agreement shall be governed by its own terms.

   7.3 Survival of Representations, Warranties and Covenants

   All representations, warranties and covenants in this Agreement or the Plan
of Merger or in any instrument delivered pursuant hereto or thereto shall expire
on, and be terminated and extinguished at, the Effective Time, other than
covenants that by their terms are to be performed after the Effective Time
(including Sections 5.13 and 5.17); provided that no such representations,
warranties or covenants shall be deemed to be terminated or extinguished so as
to deprive BB&T or BankFirst (or any director, officer or controlling person
thereof) of any defense at law or in equity which otherwise would be available
against the claims of any person, including, without limitation, any shareholder
or former shareholder of either BB&T or BankFirst, the aforesaid
representations, warranties and covenants being material inducements to
consummation by BB&T and BankFirst of the transactions contemplated herein.

   7.4 Waiver

   Except with respect to any required regulatory approval or other condition
required by law, each party hereto, by written instrument signed by an executive
officer of such party, may at any time (whether before or after approval of the
Agreement and the Plan of Merger by the BankFirst shareholders) extend the time
for the performance of any of the obligations or other acts of the other party
hereto and may waive (i) any inaccuracies of the other party in the
representations or warranties contained in this Agreement, the Plan of Merger or
any document delivered pursuant hereto or thereto, (ii) compliance with any of
the covenants, undertakings or agreements of the other party, or satisfaction of
any of the conditions precedent to its obligations, contained herein or in the
Plan of Merger, or (iii) the performance by the other party of any of its
obligations set out herein or therein; provided that no such extension or
waiver, or amendment or supplement pursuant to this Section 7.4, executed after
approval by the BankFirst shareholders of this Agreement and the Plan of Merger,
shall reduce either the Common Exchange Ratio, the Preferred Exchange Ratio or
the payment terms for fractional interests.

   7.5 Amendment or Supplement

   This Agreement or the Plan of Merger may be amended or supplemented at any
time in writing by mutual agreement of BB&T and BankFirst, subject to the
proviso to Section 7.4.

  17, 1996 between BB&T and Branch Banking and Trust Company, as Rights Agent,
  relating to BB&T's Series B Junior Participating Preferred Stock, $5.00 par
  value per share ("BB&T Common Stock") issued and outstanding immediately prior
  to the Effective Time shall continue to be issued and outstanding.

     (c) Until surrendered, each outstanding certificate which prior to the
  Effective Time represented one or more shares of BankFirst Common Stock or
  BankFirst Preferred Stock shall be deemed upon the Effective Time for all
  purposes to represent only the right to receive the Merger Consideration and
  any declared and unpaid dividends (with respect to BankFirst Common Stock) or
  accrued and unpaid dividends (with respect to BankFirst Preferred Stock). No
  interest will be paid or accrued on the Merger Consideration upon the
  surrender of the certificate or certificates representing shares of BankFirst
  Common Stock or BankFirst Preferred Stock. With respect to any certificate for
  BankFirst Common Stock or Bank First Preferred Stock that has been lost or
  destroyed, BB&T shall pay the Merger Consideration attributable to such
  certificate upon receipt of a surety bond or other adequate indemnity as
  required in accordance with BB&T's standard policy, and evidence reasonably
  satisfactory to BB&T of ownership of the shares represented thereby. After the
  Effective Time, BankFirst's transfer books shall be closed and no transfer of
  the shares of BankFirst Common Stock or BankFirst Preferred Stock outstanding
  immediately prior to the Effective Time shall be made on the stock transfer
  books of the Surviving Corporation.

                                       1

     (d) Promptly after the Effective Time, BB&T shall cause to be delivered or
  mailed to each BankFirst shareholder a form of letter of transmittal and
  instructions for use in effecting the surrender of the certificates which,
  immediately prior to the Effective Time, represented any shares of BankFirst
  Common Stock or BankFirst Preferred Stock. Upon surrender of such certificates
  or other evidence of ownership meeting the requirements of Section 4(c),
  together with such letter of transmittal duly executed and completed in
  accordance with the instructions thereto, and such other documents as may be
  reasonably requested, BB&T shall promptly cause the transfer to the persons
  entitled thereto of the Merger Consideration and any declared and unpaid
  dividends (with respect to BankFirst Common Stock) or accrued and unpaid
  dividends (with respect to BankFirst Preferred Stock).

     (e) The Surviving Corporation shall pay any dividends or other
  distributions with a record date prior to the Effective Time which have been
  declared or made by BankFirst in respect of shares of BankFirst Common Stock
  in accordance with the terms of the Agreement and which remain unpaid at the
  Effective Time, subject to compliance by BankFirst with Section 5.9(b) of the
  Agreement. At the time of the Closing and incident thereto, BankFirst shall
  pay a per share dividend in respect of shares of BankFirst Preferred Stock
  equal to the product of $.0625 times a fraction, the numerator of which is the
  number of days following the payment date of the BankFirst Preferred Stock
  dividend preceding the Closing Date and the denominator of which is 91. Such
  payment shall constitute the sole right of the holders of the BankFirst
  Preferred Stock to a dividend with respect to such BankFirst Preferred Stock.
  To the extent permitted by law, former shareholders of record of BankFirst
  shall be entitled to vote after the Effective Time at any meeting of BB&T
  shareholders the number of whole shares of BB&T Common Stock into which their
  respective shares of BankFirst Common Stock or BankFirst Preferred Stock are
  converted, regardless of whether such holders have exchanged their
  certificates representing BankFirst Common Stock or BankFirst Preferred Stock
  for certificates representing BB&T Common Stock in accordance with the
  provisions of the Agreement. Whenever a dividend or other distribution is
  declared by BB&T on the BB&T Common Stock, the record date for which is at or
  after the Effective Time, the declaration shall include dividends or other
  distributions on all shares of BB&T Common Stock issuable pursuant to the
  Agreement, but no dividend or other distribution payable to the holders of
  record of BB&T Common Stock as of any time subsequent to the Effective Time
  shall be delivered to the holder of any certificate representing BankFirst
  Common Stock or BankFirst Preferred Stock until such holder surrenders such
  certificate for exchange as provided in this Section 4. Upon surrender of such
  certificate, both the BB&T Common Stock certificate and any undelivered
  dividends and cash payments payable hereunder (without interest) shall be
  delivered and paid with respect to the shares of BankFirst Common Stock or
  BankFirst Preferred Stock represented by such certificate.

   Section 5. Merger Consideration

   As used herein, the term "Merger Consideration" shall mean the number of
shares of BB&T Common Stock (to the nearest one-hundredth of a share) to be
exchanged for each share of BankFirst Common Stock or BankFirst Preferred Stock
issued and outstanding as of the Effective Time and cash (without interest) to
be payable in exchange for any fractional share of BB&T Common Stock which would
otherwise be distributable to a BankFirst shareholder as provided in Section
4(d), determined as follows:

     (a) The number of shares of BB&T Common Stock to be issued for each issued
  and outstanding share of BankFirst Common Stock shall be in the ratio of .4554
  shares of BB&T Common Stock for each share of BankFirst Common Stock (the
  "Common Exchange Ratio"); and the number of shares of BB&T Common Stock to be
  issued for each issued and outstanding share of BankFirst Preferred Stock
  shall be in the ratio of 1.4060 shares of BB&T Common Stock for each share of
  BankFirst Preferred Stock (the "Preferred Exchange Ratio").

     (b) The amount of cash payable with respect to any fractional share of BB&T
  Common Stock shall be determined by multiplying the fractional part of such
  share by the Closing Value. The "Closing Value" shall mean the 4:00 p.m.
  eastern time closing price per share of BB&T Common Stock on the NYSE on the
  Closing Date as reported on NYSEnet.com.

                                       2

   Section 6. Conversion of Stock Options

     (a) At the Effective Time, each option granted under BankFirst's Incentive
  Stock Option Plan dated October 11, 1995 (the "Stock Option Plan") to acquire
  shares of BankFirst Common Stock then outstanding (and which by its terms does
  not lapse on or before the Effective Time), whether or not then exercisable (a
  "Stock Option"), shall be converted into and become rights with respect to
  BB&T Common Stock, and BB&T shall assume each Stock Option in accordance with
  the terms of the Stock Option Plan, except that from and after the Effective
  Time (i) BB&T and its Compensation Committee shall be substituted for
  BankFirst and the Compensation Committee of BankFirst's Board of Directors
  administering the Stock Option Plan, (ii) each Stock Option assumed by BB&T
  may be exercised solely for shares of BB&T Common Stock, (iii) the number of
  shares of BB&T Common Stock subject to each such Stock Option shall be the
  number of whole shares of BB&T (omitting any fractional share) determined by
  multiplying the number of shares of BankFirst Common Stock subject to such
  Stock Option immediately prior to the Effective Time by the Common Exchange
  Ratio, and (iv) the per share exercise price under each such Stock Option
  shall be adjusted by dividing the per share exercise price under each such
  Stock Option by the Common Exchange Ratio and rounding up to the nearest cent.
  Notwithstanding the foregoing, BB&T may at its election substitute as of the
  Effective Time options under the BB&T Corporation 1995 Omnibus Stock Incentive
  Plan or any other duly adopted comparable plan (in either case, the "BB&T
  Option Plan") for all or a part of the Stock Options, subject to the following
  conditions: (A) the requirements of (iii) and (iv) above shall be met; (B)
  such substitution shall not constitute a modification, extension or renewal of
  any of the Stock Options which are incentive stock options; and (C) the
  substituted options shall continue in effect on the same terms and conditions
  as provided in the Stock Options and the Stock Option Plan granting each Stock
  Option. Each grant of a converted or substitute option to any individual who
  subsequent to the Merger will be a director or officer of BB&T as construed
  under Rule 16b-3 shall be approved in accordance with the provisions of Rule
  16b-3. Each Stock Option which is an incentive stock option shall be adjusted
  as required by Section 424 of the Code, and the Regulations promulgated
  thereunder, so as to continue as an incentive stock option under Section
  424(a) of the Code, and so as not to constitute a modification, extension, or
  renewal of the option within the meaning of Section 424(h) of the Code. BB&T
  and BankFirst shall take all necessary steps to effectuate the foregoing
  provisions of this Section 6. BB&T has reserved and shall continue to reserve
  adequate shares, duly registered with the Securities and Exchange Commission,
  of BB&T Common Stock for delivery upon exercise of any converted or substitute
  options. As soon as practicable after the Effective Time, if it has not
  already done so, and to the extent BankFirst shall have a registration
  statement in effect or an obligation to file a registration statement, BB&T
  shall file a registration statement on Form S-3 or Form S-8, as the case may
  be (or any successor or other appropriate forms), with respect to the shares
  of BB&T Common Stock subject to converted or substitute options and shall use
  its reasonable efforts to maintain the effectiveness of such registration
  statement (and maintain the current status of the prospectus or prospectuses
  contained therein) for so long as such converted or substitute options remain
  outstanding. With respect to those individuals, if any, who subsequent to the
  Merger may be subject to the reporting requirements under Section 16(a) of the
  Securities Exchange Act of 1934, as amended (the "Exchange Act"), BB&T shall
  administer the Stock Option Plan assumed pursuant to this Section 6 (or the
  BB&T Option Plan, if applicable) in a manner that complies with Rule 16b-3
  promulgated under the Exchange Act to the extent necessary to preserve for
  such individuals the benefits of Rule 16b-3 to the extent such benefits were
  available to them prior to the Effective Time.

     (b) As soon as practicable following the Effective Time, BB&T shall deliver
  to the participants receiving converted options under the BB&T Option Plan an
  appropriate notice setting forth such participant's rights pursuant thereto.

   Section 7. Amendment. At any time before the Effective Time, this Plan of
Merger may be amended, provided that no such amendment executed after approval
by the BankFirst shareholders of the Agreement and this Plan of Merger shall
modify either the amount or the form of the consideration to be provided to
holders of BankFirst Common Stock upon consummation of the Merger.

   Offer" or an "Exchange Offer," respectively); or

           (ii) the holders of Issuer Common Stock shall not have approved the

   Bank Control Act of 1978) seeking the consent to an Acquisition Transaction
   from any federal or state governmental or regulatory authority or agency.

<PAGE>

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 BankFirst 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 BankFirst to issue the Option Shares or
Holder to exercise the Option, or until 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).

       (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 AUGUST 22,
       2000. 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

<PAGE>

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.

       (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
BankFirst 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

<PAGE>

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 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

<PAGE>

   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 Nasdaq National
   Market System 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.)

           (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).

<PAGE>

       (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.

       (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

<PAGE>

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
Nasdaq National Market (or if Issuer Common Stock is not quoted on the Nasdaq
National Market, 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 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

<PAGE>

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

           (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

<PAGE>

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)

<PAGE>

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 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 defense of such action notwithstanding its obligation to bear fees
and expenses of such 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 promulgated under the
Securities Act. 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 then authorized for quotation or
trading or listing on the Nasdaq National Market System 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 Nasdaq
National Market System or any other securities exchange or any automated

<PAGE>

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 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

<PAGE>

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 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; provided, however, that until following the
date on which the Federal Reserve Board has approved Grantee's application to
acquire the shares of Issuer Common Stock subject to the Option, Grantee shall
not assign its rights hereunder except in (i) a widely dispersed public
distribution, (ii) a private placement in which no one party acquires the right
to purchase five percent or more of Issuer's voting shares, (iii) an assignment
to a single party (e.g., a broker or investment banker) for the purpose of
conducting a widely dispersed public distribution on Grantee's behalf, or (iv)
any other manner expressly approved by the Federal Reserve Board. 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.

                  [remainder of page intentionally left blank]

    IN WITNESS WHEREOF, Issuer and Grantee have caused this Agreement to be
