                     AGREEMENT AND PLAN OF REORGANIZATION
                     ------------------------------------


     THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made and
entered into as of May 20, 1999 by and between PREMIER BANCSHARES, INC.
("Premier"), a corporation organized and existing under the laws of the State of
Georgia, with its principal office located in Atlanta, Georgia; PMB ACQUISITION
CORP. II ("PMB"), a corporation organized and existing under the laws of the
State of Georgia and a wholly owned subsidiary of Premier; and BANK ATLANTA
("Bank Atlanta"), a commercial bank organized and existing under the laws of the
State of Georgia, with its principal office located in Decatur, Georgia.

                                   PREAMBLE
                                   --------

     The Boards of Directors of Bank Atlanta and Premier are of the opinion that
the transactions described herein are in the best interests of the parties and
their respective shareholders.  This Agreement provides for the acquisition of
Bank Atlanta by Premier pursuant to the merger (the "Merger") of PMB with and
into Bank Atlanta, and following the merger Bank Atlanta will become a wholly-
owned subsidiary of Premier.  At the effective time of the Merger, the
outstanding shares of the common stock of Bank Atlanta shall be converted into
the right to receive shares of the common stock of Premier.  As a result,
shareholders of Bank Atlanta will become shareholders of Premier.  The
transactions described in this Agreement are subject to the approvals of the
Boards of Directors of Bank Atlanta, Premier and PMB, the shareholders of Bank
Atlanta and PMB, the Georgia Department of Banking and Finance, the Board of
Governors of the Federal Reserve System (or the Federal Reserve Bank of Atlanta
acting pursuant to delegated authority), the Federal Deposit Insurance
Corporation and the satisfaction of certain other conditions described in this
Agreement. It is the intention of the parties to this Agreement that the Merger
(i) for federal income tax purposes shall qualify as a "reorganization" within
the meaning of Section 368(a) of the Internal Revenue Code and (ii) for
accounting purposes shall be accounted for as a "pooling of interests"
transaction.

     As a condition and inducement to Premier's willingness to consummate the
transactions contemplated by this Agreement, each member of the Board of
Directors of Bank Atlanta will execute and deliver to Premier an agreement (a
"Support Agreement") within ten (10) calendar days of the date of this
Agreement, in substantially the form of Exhibit 5 to this Agreement.
                                        ---------

     Certain terms used in this Agreement are defined in Section 11.1 of this
Agreement.

     NOW, THEREFORE, in consideration of the above and the mutual warranties,
representations, covenants and agreements set forth herein, the receipt and
legal sufficiency of which are hereby acknowledged, the Parties hereto agree as
follows:

     (a)  Each share of Premier Common Stock issued and outstanding immediately
prior to the Effective Time shall remain issued and outstanding from and after
the Effective Time.

     (b)  Each share of PMB Common Stock issued and outstanding immediately
prior to the Effective Time shall be converted into one fully paid and non-
assessable share of Surviving Bank Common Stock.

     (c)  Each share of Bank Atlanta Common Stock (excluding shares held by Bank
Atlanta or by any Premier Company, which shares shall be canceled as provided in
Section 3.3 of this Agreement, in each case other than in a fiduciary capacity
or in satisfaction of debts previously contracted) issued and outstanding at the
Effective Time shall cease to be outstanding and shall be converted into and
exchanged for the right to receive 1.25 shares of Premier Common Stock, subject
to possible adjustment as provided in Section 3.1(d) (the "Exchange Ratio"):

     (d)  The Exchange Ratio shall be adjusted in the event both of the
following conditions are satisfied:

          (1)  the Average Closing Price shall be less than the product of (i)
     0.80 and (ii) the Starting Price; and

          (2)  (i) the quotient obtained by dividing the Average Closing Price
     by the Starting Price (such number being referred to herein as the "Premier
     Ratio") shall be less than (ii) the quotient obtained by dividing the Index
     Price on the Determination Date by the Index Price on the Starting Date
     (such number being referred to herein as the "Index Ratio").

In the event both of the above conditions are satisfied, the Exchange Ratio
shall be increased to equal the quotient obtained by dividing (1) the sum of (i)
0.75 times the difference between the Starting Price and the Average Closing
Price, and (ii) the Average Closing Price multiplied by the Exchange Ratio by
(2) the Average Closing Price. Following any such adjustment to the Exchange
Ratio as provided in this Section 3.1(d), any references in this Agreement to
the "Exchange Ratio" shall thereafter be deemed to refer to the "Exchange Ratio"
as so adjusted. The provisions of this Section 3.1(d) are subject to the
provisions of Section 10.1(j).

     For purposes of this Section 3.1(c), the following terms shall have the
meanings indicated.

          ---------------------------------------

          ---------------------------

     (a)  At the Effective Time, all rights with respect to Bank Atlanta Common
Stock pursuant to stock options granted by Bank Atlanta ("Bank Atlanta Options")
under the Bank Atlanta Stock Plans, which are outstanding at the Effective Time,
whether or not exercisable, shall be converted into and become rights with
respect to Premier Common Stock, and Premier shall assume each Bank Atlanta
Option, in accordance with the terms of the Bank Atlanta Stock Plan and stock
option agreement by which it is evidenced.  From and after the Effective Time,
(i) each Bank Atlanta Option assumed by Premier may be exercised solely for
shares of Premier Common Stock, (ii) the number of shares of Premier Common
Stock subject to such Bank Atlanta Option shall be equal to the number of shares
of Bank Atlanta Common Stock subject to such Bank Atlanta Option immediately
prior to the Effective Time multiplied by the Exchange Ratio, and (iii) the per
share exercise price under each such Bank Atlanta Option shall be adjusted by
dividing the per share exercise price under each such Bank Atlanta Option by the
Exchange Ratio and rounding down to the nearest cent.  It is intended that the
foregoing assumption shall be undertaken in a manner that will not constitute a
"modification" as defined in Section 424 of the Internal Revenue Code, as to any
stock option which is an "incentive stock option."  Bank Atlanta and Premier
agree to take all necessary steps to effect the provisions of this Section 3.4.

     (b)  Premier may, at its election, substitute, as of the Effective Time,
stock options under the Premier Bancshares, Inc. 1997 Stock Option Plan (the
"Premier Stock Option Plan") for all or a part of the Bank Atlanta Options,
subject to the following conditions: (i) the requirements of Section 3.4(a)
shall be met; (ii) such substitution shall not constitute a modification,
extension or renewal of any of the Bank Atlanta Options which are incentive
stock options; (iii) the substituted options shall continue in effect on
substantially the same terms and conditions as contained in the document
granting the Bank Atlanta Options; and (iv) each grant of a substitute option to
any individual who shall be deemed subject to Section 16 of the 1934 Act shall
have been specifically approved in advance by the full Board of Directors of
Premier or by a committee consisting solely of "non-employee" directors as
defined in Rule 16b-3.  As soon as practicable following the Effective Time,
Premier shall deliver to the participants receiving substitute options under the
Premier  Stock Option Plan an appropriate notice setting forth such
participant's rights pursuant thereto.  Premier has reserved under the Premier
Stock Option Plan adequate shares of Premier Common Stock for delivery upon
exercise of any such substituted options.

          ------------------

who would otherwise have been entitled to receive a fraction of a share of
Premier Common Stock (after taking into account all certificates delivered by
such holder) shall receive, in lieu thereof, cash (without interest) in an
amount equal to such fractional part of a share of Premier Common Stock
multiplied by the market value of one share of Premier Common Stock at the
Effective Time, in the case of shares exchanged pursuant to the Merger, or the
date of exercise, in the case of options.  The market value of one share of

may be, shall be the last sale price of the Premier Common Stock on the American
Stock Exchange, or such other exchange on which the Premier Common Stock is
listed, (as reported by The Wall Street Journal or, if not reported thereby, any
other authoritative source) on the last trading day preceding the Effective
Time, in the case of shares exchanged pursuant to the Merger, or the date of
exercise, in the case of options.  No such holder will be entitled to dividends,
voting rights, or any other rights as a shareholder in respect of any fractional
shares.

          -------------------
cause SunTrust Bank, Atlanta, or such other exchange agent selected by Premier
(the "Exchange Agent") to mail to the former holders of Bank Atlanta Common
Stock appropriate transmittal materials which shall specify that delivery shall
be effected, and risk of loss and title to the certificates theretofore
representing shares of Bank Atlanta Common Stock shall pass, only upon proper
delivery of such certificates to the Exchange Agent. After the Effective Time,
each holder of shares of Bank Atlanta Common Stock (other than shares to be
canceled pursuant to Section 3.3 of this Agreement) issued and outstanding at
the Effective Time shall surrender the certificate or certificates representing
such shares to the Exchange Agent and shall promptly upon surrender thereof
receive in exchange therefor the consideration provided in Article III of this
Agreement, together with all undelivered dividends or distributions in respect
of such shares (without interest thereon) pursuant to Section 4.2 of this
Agreement. Premier shall not be obligated to deliver the consideration to which
any former holder of Bank Atlanta Common Stock is entitled as a result of the
Merger until such holder surrenders his or her certificate or certificates
representing the shares of Bank Atlanta Common Stock for exchange as provided in
this Section 4.1. The certificate or certificates of Bank Atlanta Common Stock
so surrendered shall be duly endorsed as the Exchange Agent may require. Any
other provision of this Agreement notwithstanding, neither Premier, the
Surviving Bank, nor the Exchange Agent shall be liable to a holder of Bank
Atlanta Common Stock for any amounts paid or property delivered in good faith to
a public official pursuant to any applicable abandoned property Law.

     4.2  Rights of Former Bank Atlanta Shareholders.  At the Effective Time,
          ------------------------------------------
the stock transfer books of Bank Atlanta shall be closed as to holders of Bank
Atlanta Common Stock immediately prior to the Effective Time and no transfer of
Bank Atlanta Common Stock by any such holder shall thereafter be made or
recognized. Until surrendered for exchange in accordance with the provisions of
Section 4.1 of this Agreement, each certificate theretofore representing shares
of

                                       7
<PAGE>

Bank Atlanta Common Stock (other than shares to be canceled pursuant to Section
3.3 of this Agreement) shall from and after the Effective Time represent for all
purposes only the right to receive the consideration provided in Article III of
this Agreement in exchange therefor. To the extent permitted by Law, former
holders of record of Bank Atlanta Common Stock shall be entitled to vote after
the Effective Time at any meeting of Premier shareholders the number of whole
shares of Premier Common Stock into which their respective shares of Bank
Atlanta Common Stock are converted, regardless of whether such holders have
exchanged their certificates representing Bank Atlanta Common Stock for
certificates representing Premier Common Stock in accordance with the provisions
of this Agreement. Whenever a dividend or other distribution is declared by
Premier on the Premier 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 issuable pursuant to this Agreement, but no dividend
or other distribution payable to the holders of record of Premier Common Stock
as of any time subsequent to the Effective Time shall be delivered to the holder
of any certificate representing shares of Bank Atlanta Common Stock issued and
outstanding at the Effective Time until such holder surrenders such certificate
for exchange as provided in Section 4.1 of this Agreement. However, upon
surrender of such Bank Atlanta Common Stock certificate, both the Premier Common
Stock certificate (together with all such undelivered dividends or other
distributions without interest) and any undelivered cash payments to be paid for
fractional share interests (without interest) shall be delivered and paid with
respect to each share represented by such certificate.

     6.9   Statements True And Correct.  No statement, certificate, instrument
           ---------------------------
or other writing furnished or to be furnished by any Premier Company or any
Affiliate thereof to Bank Atlanta pursuant to this Agreement or any other
document, agreement or instrument referred to herein contains or will contain
any untrue statement of material fact or will omit to state a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. None of the information supplied or to be
supplied by any Premier Company or any Affiliate thereof for inclusion in the
Registration Statement to be filed by Premier with the SEC, will, when the
Registration Statement becomes effective, be false or misleading with respect to
any material fact, or omit to state any material fact necessary to make the
statements therein not misleading. None of the information supplied or to be
supplied by any Premier Company or any Affiliate thereof for inclusion in any
documents to be filed by any Premier Company or any Affiliate thereof with the
SEC or any other Regulatory Authority in connection with the transactions
contemplated hereby, will, at the respective time such documents are filed, be
false or misleading with respect to any material fact, or omit to state any
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. All documents that any
Premier Company or any Affiliate thereof is responsible for filing with any
Regulatory Authority in connection with the transactions contemplated hereby
will comply as to form in all material respects with the provisions of
applicable Law.

     6.10  Accounting, Tax And Regulatory Matters.  No Premier Company or any
           --------------------------------------
Affiliate thereof has taken any action, or agreed to take any action, or has any
Knowledge of any fact or circumstance that is reasonably likely to (a) prevent
the transactions contemplated hereby, including the Merger, from qualifying for
pooling-of-interests accounting treatment or treatment as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code, or (b)
materially impede or delay receipt of any Consents of Regulatory Authorities
referred to in Section 9.1(b) of this Agreement. To the Knowledge of Premier,
there exists no fact, circumstance, or reason why the requisite Consents
referred to in Sections 9.1(b) and (c) of this Agreement cannot be received in a
timely manner without the imposition of any condition or restriction of the type
described in the second sentence of such Sections 9.1(b) and (c).

     6.11  Premier Subsidiaries.  Premier has disclosed in Section 6.11 of the
           --------------------
Premier Disclosure Memorandum all of the Premier Subsidiaries as of the date of
        ---------------------
this Agreement.  Except as disclosed in Section 6.11 of the Premier Disclosure
                                                                    ----------
Memorandum, Premier or one of its Subsidiaries owns all of the issued and
- ----------
outstanding shares of capital stock of each Premier Subsidiary.  No equity
securities of any Premier Subsidiary are or may become required to be issued
(other than to another Premier Company) by reason of any Rights, and there are
no Contracts by which any Premier Subsidiary is bound to issue (other than to
another Premier Company) additional shares of its capital stock or Rights, or by
which any Premier Company is or may be bound to transfer any shares of the
capital stock of any Premier Subsidiary (other than to another Premier Company).
There are no Contracts relating to the rights of any Premier Company to vote or
to

                                       21
<PAGE>

dispose of any shares of the capital stock of any Premier Subsidiary. All of the
shares of capital stock of each Premier Subsidiary held by a Premier Company are
fully paid and nonassessable under the applicable Law of the jurisdiction in
which such Subsidiary is incorporated or organized. Each Premier Subsidiary is
either a bank, a savings association, a corporation or a limited liability
company and is duly organized, validly existing, and (as to corporations) in
good standing under the Laws of the jurisdiction in which it is organized and
has the corporate power and authority necessary for it to own, lease and operate
its Assets and to carry on its business as now conducted. Each Premier
Subsidiary is duly qualified or licensed to transact business as a foreign
corporation in good standing in the States of the United States and foreign
jurisdictions where the character of its Assets or the nature or conduct of its
business requires it to be so qualified or licensed, except for such
jurisdictions in which the failure to be so qualified or licensed is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on Premier. Each Premier Subsidiary that is a depository institution is
an "insured institution" as defined in the Federal Deposit Insurance Act and
applicable regulations thereunder, and the deposits in which are insured by the
Bank Insurance Fund or the Savings Association Insurance Fund, as appropriate.

     6.12  Reports.  Since January 1, 1997, each Premier Company has timely
           -------
filed all reports and statements, together with any amendments required to be
made with respect thereto, that it was required to file with (a) the SEC,
including, but not limited to, Forms 10-K, Forms 10-Q, Forms 8-K, and Proxy
Statements, (b) other Regulatory Authorities, and (c) any applicable state
securities or banking authorities (except failures to file which are not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on Premier). As of their respective dates, each of such reports and
documents, including the financial statements, exhibits, and schedules thereto,
complied in all material respect with all applicable Laws. As of its respective
date, each such report and document to Premier's Knowledge did not, in any
material respects, contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances under which they were
made, not misleading.

     6.13  Millennium Compliance.  Premier represents and warrants that it has
           ---------------------
tested and assessed its software, hardware, and other computer equipment to
ensure that there will not be a Year 2000 Problem. Premier further represents
and warrants that it has prepared and implemented a written plan of action to
ensure that the software, hardware, and other computer equipment owned,
licensed, or used by Premier will not be the subject of a failure in any such
software, hardware, or other computer equipment as a result of a Year 2000
Problem. Premier further represents and warrants that it has contacted and
received assurances from all key suppliers of goods and services to Premier,
including but not limited to suppliers of computer software, computer hardware,
and other computer equipment, that each of the software, hardware, and other
computer equipment owned, licensed, or used by such suppliers will not be the
subject of failures in any such software, hardware, or other computer equipment
as a result of a Year 2000 Problem.

     6.14  Allowance For Possible Loan Losses.  The allowance for possible loan
           ----------------------------------
or credit losses (the "Allowance") shown on the balance sheets of Premier
included in the most recent Premier Financial Statements dated prior to the date
of this Agreement was, and the Allowance shown on the

                                       22
<PAGE>

balance sheets of Premier included in the Premier Financial Statements as of
dates subsequent to the execution of this Agreement will be, as of the dates
thereof, adequate (within the meaning of GAAP and applicable regulatory
requirements or guidelines) to provide for losses relating to or inherent in the
loan and lease portfolios (including accrued interest receivables) of Premier
and other extensions of credit (including letters of credit and commitments to
make loans or extend credit) by Premier as of the dates thereof except where the
failure of such Allowance to be so adequate is not reasonably likely to have a
Material Adverse Effect on Premier.

     (a)   Subject to the conditions set forth in paragraph (b) below, for a
period of six (6) years after the Effective Time, Premier shall indemnify,
defend, and hold harmless the present and former directors, officers, employees,
and agents of Bank Atlanta (each, an "Indemnified Party") against all
Liabilities arising out of actions or omissions occurring at or prior to the
Effective Time (including the transactions contemplated by this Agreement) to
the full extent permitted under Georgia Law and by Bank Atlanta's Articles of
Incorporation and Bylaws as in effect on the date hereof, including provisions
relating to advances of expenses incurred in the defense of any Litigation.
Without limiting the foregoing, in any case in which approval by Premier is

the Indemnified Party, that the determination of any such approval shall be made
by independent counsel mutually agreed upon between Premier and the Indemnified
Party.

     (b)   Any Indemnified Party wishing to claim indemnification under
paragraph (a) above, upon learning of any such Liability or Litigation within
the six (6) year period after the Effective Time, shall promptly notify Premier

any legal expenses of other counsel or any other expenses subsequently incurred
by such Indemnified Parties in connection with the defense thereof, except that
if Premier elects not to assume such defense or counsel for the Indemnified
Parties and advises that there are substantive issues which raise conflicts of
interest between Premier and the Indemnified Parties, the Indemnified Parties
may retain counsel satisfactory to them, and Premier shall pay all reasonable
fees and expenses of such counsel for the Indemnified Parties promptly as
statements therefor are received; provided, however, that Premier shall be
obligated pursuant to this paragraph (b) to pay for only one firm of counsel for
all Indemnified Parties in any jurisdiction, (ii) the Indemnified Parties will
cooperate in the defense of any such Litigation; and (iii) Premier shall not be
liable for any settlement effected without its prior written consent; and
provided further that Premier shall not have any obligation hereunder to any
Indemnified Party when and if a court of competent jurisdiction shall determine,
and such determination shall have become final, that the indemnification of such
Indemnified Party in the manner contemplated hereby is prohibited by applicable
Law.

     (c)   If Premier or any of its successors or assigns shall consolidate with
or merge into any other Person and shall not be the continuing or surviving
Person of such consolidation or merger or shall transfer all or substantially
all of its assets to any Person, then and in each case, proper provision shall
be made so that the successors and assigns of Premier shall assume the
obligations set forth in this Section 8.12.

     (d)   The provisions of this Section 8.12 are intended to be for the
benefit of and shall be enforceable by, each Indemnified Party, his or her heirs
and representatives.

Ladies and Gentlemen:

       The undersigned is a shareholder of Bank Atlanta ("Bank Atlanta"), a

Atlanta ("Bank Atlanta Common Stock") will be converted into shares of common
stock of Premier ("Premier Common Stock"). This Affiliate Agreement represents
an agreement between the undersigned and Premier regarding certain rights and
obligations of the undersigned in connection with the shares of Premier to be
received by the undersigned as a result of the Merger.

       In consideration of the Merger and the mutual covenants contained herein,
the undersigned and Premier hereby agree as follows:

in Rule 405 of the Rules and Regulations of the Securities and Exchange
Commission ("SEC") under the Securities Act of 1933, as amended ("1933 Act"),
and the undersigned anticipates that the undersigned will be such an "affiliate"
at the time of the Merger.

               Initial Restriction on Disposition. The undersigned agrees that
               ----------------------------------
the undersigned will not, except by operation of law, by will or under the laws
of descent and distribution, sell, transfer, or otherwise dispose of the
undersigned's interests in, or reduce the undersigned's risk relative to, any of
the shares of Premier Common Stock into which the undersigned's shares of Bank
Atlanta Common Stock are converted upon consummation of the Merger until such
time as Premier notifies the undersigned that the requirements of SEC Accounting
Series Release Nos. 130 and 135 ("ASR 130 and 135") have been met. The
undersigned understands that ASR 130 and 135 relate to
<PAGE>

publication of financial results of post-Merger combined operations of Premier
and Bank Atlanta. Premier agrees that it will publish such results within 45
days after the end of the first fiscal quarter of Premier containing the
required period of post-Merger combined operations and that it will notify the
undersigned promptly following such publication.

          Covenants and Warranties of Undersigned. The undersigned represents,
          ---------------------------------------
warrants and agrees that:

          (a)  During the 30 days immediately preceding the effective time of
     the Merger, the undersigned will not, except by operation of law, by will,
     or under the laws of descent and distribution, sell, transfer, or otherwise
     dispose of the undersigned's interests in, or reduce the undersigned's risk
     relative to, any of the shares of Bank Atlanta Common Stock beneficially
     owned by the undersigned as of the date of the shareholders' meeting of
     Bank Atlanta held to approve the Merger.

          (b)  The Premier Common Stock received by the undersigned as a result
     of the Merger will be taken for the undersigned's own account and not for
     others, directly or indirectly, in whole or in part.

          (c)  The undersigned understands that any distribution by the
     undersigned of the Premier Common Stock has not been registered under the
     1933 Act and that shares of Premier Common Stock received pursuant to the
     Merger can only be sold by the undersigned (1) following registration under
     the 1933 Act, or (2) in conformity with the volume and other requirements
     of Rule 145(d) promulgated by the SEC as the same now exist or may
     hereafter be amended, or (3) to the extent some other exemption from
     registration under the 1933 Act might be available. The undersigned
                                                         ---------------
     understands that Premier is under no obligation to file a registration
     ----------------------------------------------------------------------
     statement with the SEC covering the disposition of the undersigned's shares
     ---------------------------------------------------------------------------
     of Premier Common Stock.
     -----------------------

     4.   Restrictions on Transfer. The undersigned understands and agrees that
          ------------------------
stop transfer instructions with respect to the shares of Premier Common Stock
received by the undersigned pursuant to the Merger will be given to Premier's
transfer agent and that there will be placed on the certificates for such
shares, or shares issued in substitution thereof, a legend stating in substance:

          "The shares represented by this certificate were issued pursuant
          to a business combination which is accounted for as a "pooling
          of interests" and may not be sold, nor may the owner thereof
          reduce his risks relative thereto in any way, until such time as
          Premier has published the financial results covering at least 30
          days of combined operations after the effective date of the
          merger through which the business combination was effected. In
          addition, the shares represented by this certificate may not be
          sold, transferred or otherwise disposed of except or unless (a)
          covered by an effective registration statement under the
          Securities Act of 1933, as amended, (b) in accordance with (i)
          Rule

                                       2
<PAGE>

          145(d) (in the case of shares issued to an individual who is not
          an affiliate of Premier) or (ii) Rule 144 (in the case of shares
          issued to an individual who is an affiliate of Premier) of the
          Rules and Regulations of such Act, or (c) in accordance with a
          legal opinion satisfactory to counsel for Premier that such sale
          or transfer is otherwise exempt from the registration
          requirements of such Act."

Such legend will also be placed on any certificate representing Premier
securities issued subsequent to the original issuance of Premier Common
Stock pursuant to the Merger as a result of any stock dividend, stock
split or other recapitalization as long as Premier Common Stock issued to
the undersigned pursuant to the Merger has not been transferred in such
manner to justify the removal of the legend therefrom. If the provisions
of Rules 144 and 145 are amended to eliminate restrictions applicable to
the Premier Common Stock received by the undersigned pursuant to the
Merger, or at the expiration of the restrictive period set forth in Rule
145(d), Premier, upon the request of the undersigned, will cause the
certificates representing the shares of Premier Common Stock issued to the
undersigned in connection with the Merger to be reissued free of any
legend relating to the restrictions set forth in Rules 144 and 145(d) upon
receipt by Premier of an opinion of its counsel to the effect that such
legend may be removed.

     5.   Understanding of Restrictions on Dispositions. The undersigned has
          ---------------------------------------------
carefully read the Agreement and this Affiliate Agreement and discussed
their requirements and impact upon his or her ability to sell, transfer or
otherwise dispose of the shares of Premier Common Stock received by the
undersigned, to the extent the undersigned believes necessary, with the
undersigned's counsel or counsel for Bank Atlanta.

     6.   Filing of Reports by Premier. Premier agrees, for a period of
          ----------------------------
two years after the effective date of the Merger, to file on a timely
basis all reports required to be filed by it pursuant to Section 13 of the
Securities Exchange Act of 1934, as amended, so that the public
information provisions of Rule 145(d) promulgated by the SEC as the same
are presently in effect will be available to the undersigned in the event
the undersigned desires to transfer any shares of Premier Common Stock
issued to the undersigned pursuant to the Merger.

     7.   Transfer Under Rule 145(d). If the undersigned desires to sell
          --------------------------
or otherwise transfer the shares of Premier Common Stock received by the
undersigned in connection with the Merger at any time during the
restrictive period set forth in Rule 145(d), the undersigned will provide
the necessary representation letter to the transfer agent for the Premier
Common Stock together with such additional information as the transfer
agent may reasonably request. If Premier's counsel concludes that such
proposed sale or transfer complies with the requirements of Rule 145(d),
Premier shall cause such counsel to provide such opinions as may be
necessary to Premier's transfer agent so that the undersigned may complete
the proposed sale or transfer.

     8.   Acknowledgments. The undersigned recognizes and agrees that the
          ---------------
foregoing provisions also apply to (a) the undersigned's spouse, (b) any
relative of the undersigned or of the

                                    3
<PAGE>

undersigned's spouse who has the same home as the undersigned, (c) any trust or
estate in which the undersigned, the undersigned's spouse, and any such relative
collectively own at least a 10% beneficial interest or of which any of the
foregoing serves as trustee, executor or in any similar capacity and (d) any
corporation or other organization in which the undersigned, the undersigned's
spouse and any such relative who collectively owns at least 10% of any class of
equity securities or of the equity interest. The undersigned further recognizes
that, in the event that the undersigned is a director or officer of Premier or
becomes a director or officer of Premier upon consummation of the Merger, among
other things, any sale of Premier Common Stock by the undersigned within a
period of less than six months following the effective time of the Merger may
subject the undersigned to liability pursuant to Section 16(b) of the Securities
Exchange Act of 1934, as amended.

          9.   Miscellaneous. This Affiliate Agreement is the complete agreement
               -------------
between Premier and the undersigned concerning the subject matter hereof. Any
notice required to be sent to any party hereunder shall be sent by registered or
certified mail, return receipt requested, using the addresses set forth herein
or such other address as shall be furnished in writing by the parties. This
Affiliate Agreement shall be governed by the laws of the State of Georgia.
