                 WHEREAS, the respective Boards of Directors of ST-Sub and SBG
deem it in the best interests of ST-Sub and of SBG, respectively, and of their

Time of the Merger, the directors of the Surviving Corporation shall be those
persons theretofore serving as directors of ST-Sub and the officers of the

                                   ARTICLE II

                   CONVERSION OF CONSTITUENTS' CAPITAL SHARES


         Section 2.1      Manner of Conversion of SBG Shares.  Subject to the
provisions hereof, as of the Effective Time of the Merger and by virtue of the
Merger and without any further action on the part of the holder of any shares
of common stock of SBG, par value $1.00 (the "SBG Shares"):

         (a)     All SBG Shares which are held by SBG as treasury stock, if
                 any, shall be canceled and retired and no consideration shall
                 be paid or delivered in exchange therefor.

         (b)     Subject to the terms and conditions of this Agreement,
                 including, without limitation, Section 2.3 hereof and except
                 with regard to Dissenting SBG Shares (as hereinafter defined),
                 each SBG Share outstanding immediately prior to the Effective
                 Time of the Merger shall be converted into the right to
                 receive 0.5275665 shares of common stock of SouthTrust (and
                 the rights associated therewith issued pursuant to a Rights
                 Agreement dated February 22, 1989 between SouthTrust and
                 Mellon Bank, N.A.) (together, the "SouthTrust Shares") (such
                 fraction, as may be adjusted, as provided herein, being
                 hereinafter referred to as the "Conversion Ratio").  The
                 Conversion Ratio, including the number of SouthTrust Shares
                 issuable in the Merger, shall be subject to an appropriate
                 adjustment in the event of any stock split, reverse stock
                 split, dividend payable in SouthTrust Shares, reclassification
                 or similar distribution whereby SouthTrust issues SouthTrust
                 Shares or any securities convertible into or exchangeable for
                 SouthTrust Shares without receiving any consideration in
                 exchange therefor, provided that the record date of such
                 transaction is a date after the date of this Agreement and
                 prior to the Effective Time of the Merger.  The Conversion
                 Ratio also is subject to an adjustment, in the sole discretion
                 of SouthTrust, upon the occurrence of certain conditions
                 specified in Section 9.9 hereof.

         (c)     Each outstanding SBG Share, the holder of which has demanded
                 and perfected his demand for payment of the "fair" value of
                 such share in accordance with Sections 14-2-1301 et seq. of
                 the Georgia Business Corporation Code (the "Dissent
                 Provisions"), to the extent applicable, and has not
                 effectively withdrawn or lost his right to such appraisal (the
                 "Dissenting SBG Shares"), shall not be converted into or
                 represent a right to receive the SouthTrust Shares issuable in
                 the Merger but the holder thereof shall be entitled only to
                 such rights as are granted by the Dissent Provisions.  SBG
                 shall give SouthTrust prompt notice upon receipt by SBG of any
                 written objection to the Merger and any written demands for
                 payment of the fair value of SBG Shares, and of withdrawals of
                 such demands, and any other instruments provided to SBG
                 pursuant to the Dissent Provisions (any shareholder duly
                 making such demand being hereinafter called a "Dissenting
                 Shareholder").  Each Dissenting Shareholder who becomes
                 entitled, pursuant to the Dissent Provisions, to payment of
                 fair value for any SBG Shares held by such Dissenting
                 Shareholder shall receive payment therefor from the Surviving
                 Corporation (but only after the amount thereof shall have been
                 agreed upon or at the times and in the amounts required by the
                 Dissent Provisions) and all of such Dissenting Shareholder's
                 SBG Shares shall be canceled.  Neither SBG nor the Surviving
                 Corporation shall, except with the prior written consent of
                 SouthTrust, voluntarily make any payment with respect to, or
                 settle or offer to





                                      A-8

                 settle, any demand for payment by any Dissenting Shareholder.
                 If any Dissenting Shareholder shall have failed to perfect or
                 shall have effectively withdrawn or lost such right to demand
                 payment of fair value, the SBG Shares held by such Dissenting
                 Shareholder shall thereupon be deemed to have been converted
                 into the right to receive the consideration to be issued in
                 the Merger as provided by this Agreement.

         Section 2.2      SBG Stock Options and Related Matters.  (a)  As of
the Effective Time of the Merger, all rights with respect to the SBG Shares
issuable pursuant to the exercise of stock options ("SBG Options") granted by
SBG under stock option plans of SBG (the "SBG Stock Option Plans"), which are
outstanding at the Effective Time of the Merger, whether or not such SBG
Options are then exercisable, shall, subject to this section, be assumed by
SouthTrust in accordance with the terms of the particular SBG Stock Option Plan
under which such SBG Options were issued and the stock option agreement by
which such SBG Options are evidenced.  From and after the Effective Time of the
Merger, (i) each SBG Option assumed by SouthTrust hereunder may be exercised
solely for SouthTrust Shares, (ii) the number of SouthTrust Shares subject to
such SBG Option shall be equal to the number of SBG Shares subject to such SBG
Option immediately prior to the Effective Time of the Merger multiplied by the
Conversion Ratio and (iii) the per share exercise price under each such SBG
Option shall be adjusted by dividing the per share exercise price under each
such SBG Option by the Conversion Ratio and rounding down to the nearest cent.

                 (b)      At all times after the Effective Time of the Merger,
SouthTrust shall reserve for issuance such number of SouthTrust Shares as shall
be necessary to permit the exercise of the SBG Options in the manner
contemplated by this Agreement.  At or prior to, or at the election of
SouthTrust within a reasonable time (not to exceed 30 days) after, the
Effective Time of the Merger, SouthTrust shall file a Registration Statement on
Form S-3 or Form S-8, as the case may be (or any successor or other appropriate
form), with respect to the SouthTrust Shares subject to the SBG Options and
shall use its best efforts to maintain the effectiveness of such registration
statement or registration statements (and maintain the current status of the
prospectus or prospectuses contained therein) for so long as any of the SBG
Options remain outstanding.  SouthTrust shall make any filings required under
any applicable state securities laws to qualify the SouthTrust Shares subject
to such SBG Options for resale thereunder.

                 (c)      The number of SouthTrust Shares subject to the SBG
Options to be assumed by SouthTrust hereunder and the exercise price thereof
shall, from and after the Effective Time of the Merger, be subject to
appropriate adjustment in the event of the occurrence of any transaction
described in Section 2.1(b) hereof if the record date with respect to such
transaction is on or after the Effective Time of the Merger.

                 (d)      It is intended that the foregoing assumption of SBG
Options shall be undertaken in a manner that will not constitute a
"modification" as defined in Section 424 of the Code as to any stock option
which is an incentive stock option as defined in Section 422 of the Code.  All
restrictions or limitations on transfer with respect to SBG Shares awarded
under a SBG Stock Option Plan ("Restricted Stock"), to the extent that such
restrictions or limitations shall not have already lapsed, shall remain in full
force and effect with respect to the SouthTrust Shares into which such
Restricted Stock is converted pursuant to this Agreement, unless such
restrictions arise under the Securities Act of 1933 and are eliminated by
virtue of the Registration Statement described in Section 6.6, below.  Except
as otherwise provided herein, (i) the provisions of the SBG Stock Option Plans
that provide for the issuance or grant of any other interest in respect of the
capital stock of SBG shall be deleted as of the Effective Time of the Merger
and (ii) SBG shall take all reasonable steps to ensure that following the
Effective Time of the Merger no holder of SBG Options shall have any right
thereunder to acquire any equity securities of SBG.

                 (e)      SBG acknowledges that the holders of SBG Options who
may become or be deemed to be executive officers or directors of SouthTrust
after the Effective Time of the Merger may be subject to the short-swing sale
restrictions of the Securities Exchange Act of 1934 and regulations promulgated
thereunder.

                 (f)      At the election of SouthTrust, SBG shall use its best
efforts to procure from each holder of SBG Options, and shall deliver to
SouthTrust at the Closing, an executed acknowledgement of the treatment and
disposition of such holder's SBG Options, as provided for under Section 2.2 of
this Agreement.

         Section 2.3      Fractional Shares.  Notwithstanding any other
provision of this Agreement, each holder of SBG Shares converted pursuant to
the Merger, and each holder of SBG Options assumed by SouthTrust pursuant to
this Agreement, who would otherwise have been entitled to receive a fraction of
a SouthTrust Share (after taking into account all certificates delivered by
such holder), shall receive, in lieu thereof, cash (without interest) in an





                                      A-9
<PAGE>   16
amount equal to such fractional part of such SouthTrust Share, multiplied by
the market value of one SouthTrust Share at the Effective Time of the Merger in
the case of shares exchanged pursuant to the Merger or at the date of exercise
in the case of SBG Options to be exercised for SouthTrust Shares.  The market
value of one SouthTrust Share at the Effective Time of the Merger or the date
of exercise, as the case may be, shall be the last sale price of such
SouthTrust Shares, as reported by The Nasdaq Stock Market-National Market
("Nasdaq") on the last business day preceding the Effective Time of the Merger
or the date of exercise, as the case may be, or, if the SouthTrust Shares
hereafter become listed for trading on any national securities exchange
registered under the Securities Exchange Act of 1934, the last sale price of
such SouthTrust Shares on the applicable date as reported on the principal
securities exchange on which the SouthTrust Shares are then listed for trading.
No such holder will be entitled to dividends, voting rights or any other rights
as a shareholder in respect of any fractional share.

         Section 2.4      Effectuating Conversion  (a)  The Trust and Financial
Services Division of SouthTrust Bank of Alabama, National Association, or such
other institution as SouthTrust and SouthTrust Bank of Alabama, National
Association, may designate, shall serve as the exchange agent (the "Exchange
Agent").  The Exchange Agent may employ sub-agents in connection with
performing its duties.  As of the Effective Time of the Merger, SouthTrust will
deliver or cause to be delivered to the Exchange Agent the consideration to be
paid by SouthTrust for the SBG Shares, along with the appropriate cash payment
in lieu of fractional interests in SouthTrust Shares.  As promptly as
practicable after the Effective Time of the Merger, the Exchange Agent shall
send or cause to be sent to each former holder of record of SBG Shares
transmittal materials (the "Letter of Transmittal") for use in exchanging their
certificates formerly representing SBG Shares for the consideration provided
for in this Agreement.  The Letter of Transmittal will contain instructions
with respect to the surrender of certificates representing SBG Shares and the
receipt of the consideration contemplated by this Agreement and will require
each holder of SBG Shares to transfer good and marketable title to such SBG
Shares to SouthTrust, free and clear of all liens, claims and encumbrances.
Amounts that would have been payable to Dissenting Shareholders for SBG Shares
but for the fact of their dissent in accordance with the provisions of Section
2.1(c) hereof shall be returned by the Exchange Agent to SouthTrust as promptly
as is practicable.

                 (b)      At the Effective Time of the Merger, the stock
transfer books of SBG shall be closed as to holders of SBG Shares immediately
prior to the Effective Time of the Merger and no transfer of SBG Shares by any
such holder shall thereafter be made or recognized and each outstanding
certificate formerly representing SBG Shares shall, without any action on the
part of any holder thereof, no longer represent SBG Shares.  If, after the
Effective Time of the Merger, certificates are properly presented to the
Exchange Agent, such certificates shall be exchanged for the consideration
contemplated by this Agreement into which the SBG Shares represented thereby
were converted in the Merger.

                 (c)      In the event that any holder of SBG Shares is unable
to deliver the certificate which represents such holder's SBG Shares,
SouthTrust, in the absence of actual notice that any SBG Shares theretofore
represented by any such certificate have been acquired by a bona fide
purchaser, shall deliver to such holder the consideration contemplated by this
Agreement and the amount of cash representing fractional SouthTrust Shares to
which such holder is entitled in accordance with the provisions of this
Agreement upon the presentation of all of the following:

                 (i)      An affidavit or other evidence to the reasonable
                          satisfaction of SouthTrust that any such certificate
                          has been lost, wrongfully taken or destroyed;

                 (ii)     Such security or indemnity as may be reasonably
                          requested by SouthTrust to indemnify and hold
                          SouthTrust harmless; and

                 (iii)    Evidence to the satisfaction of SouthTrust that such
                          holder is the owner of the SBG Shares theretofore
                          represented by each certificate claimed by such
                          holder to be lost, wrongfully taken or destroyed and
                          that such holder is the person who would be entitled
                          to present each such certificate for exchange
                          pursuant to this Agreement.

                 (d)      In the event that the delivery of the consideration
contemplated by this Agreement and the amount of cash representing fractional
SouthTrust Shares are to be made to a person other than the person in





                                     A-10
<PAGE>   17
whose name any certificate representing SBG Shares surrendered is registered,
such certificate so surrendered shall be properly endorsed (or accompanied by
an appropriate instrument of transfer), with the signature(s) appropriately
guaranteed, and otherwise in proper form for transfer, and the person
requesting such delivery shall pay any transfer or other taxes required by
reason of the delivery to a person other than the registered holder of such
certificate surrendered or establish to the satisfaction of SouthTrust that
such tax has been paid or is not applicable.

                 (e)      No holder of SBG Shares shall be entitled to receive
any dividends or distributions declared or made with respect to the SouthTrust
Shares with a record date before the Effective Time of the Merger.  Neither the
consideration contemplated by this Agreement, any amount of cash representing
fractional SouthTrust Shares nor any dividend or other distribution with
respect to SouthTrust Shares where the record date thereof is on or after the
Effective Time of the Merger shall be paid to the holder of any unsurrendered
certificate or certificates representing SBG Shares, and SouthTrust shall not
be obligated to deliver any of the consideration contemplated by this
Agreement, any amount of cash representing fractional SouthTrust Shares or any
such dividend or other distribution with respect to SouthTrust Shares until
such holder shall surrender the certificate or certificates representing SBG
Shares as provided for by the Agreement.  Subject to applicable laws, following
surrender of any such certificate or certificates, there shall be paid to the
holder of the certificate or certificates then representing SouthTrust Shares
issued in the Merger, without interest at the time of such surrender, the
consideration contemplated by this Agreement, the amount of any cash
representing fractional SouthTrust Shares and the amount of any dividends or
other distributions with respect to SouthTrust Shares to which such holder is
entitled as a holder of SouthTrust Shares and which are payable to holders of
record of SouthTrust Shares on or after the Effective Time of the Merger and
prior to the surrender and exchange of the certificates, but if the payment
date is subsequent to the surrender, payment of such distributions shall be
made on the applicable payment date.

         Section 2.5      Laws of Escheat.  If any of the consideration due or
other payments to be paid or delivered to the holders of SBG Shares is not paid
or delivered within the time period specified by any applicable laws concerning
abandoned property, escheat or similar laws, and if such failure to pay or
deliver such consideration occurs or arises out of the fact that such property
is not claimed by the proper owner thereof, SouthTrust or the Exchange Agent
shall be entitled to dispose of any such consideration or other payments in
accordance with applicable laws concerning abandoned property, escheat or
similar laws.  Any other provision of this Agreement notwithstanding, none of
SBG, SouthTrust, ST-Sub, the Exchange Agent, nor any other person acting on
their behalf shall be liable to a holder of SBG Shares for any amount paid or
property delivered in good faith to a public official pursuant to and in
accordance with any applicable abandoned property, escheat or similar law.



                                  ARTICLE III

                     REPRESENTATIONS AND WARRANTIES OF SBG

is now being conducted, and SBG is duly licensed or qualified to do business in
Georgia and elsewhere where the nature of the business conducted by it or the
character or location of the properties and assets owned or leased by it make
such qualification necessary, except where the failure to be so licensed or
qualified would not have a material adverse effect on the business, assets,
operations, financial condition or results of operations of SBG (such business,
assets, operations, financial condition or results of operations hereinafter
collectively referred to as the "Condition of SBG") on a consolidated basis.
SBG is duly registered as a bank holding company under the Bank Holding Company
Act of 1956, as amended.  True and correct copies of the Articles or

regulatory and other authorizations, permits and licenses necessary for each of
them to own or lease its properties and assets and to carry on its business as

Authorities, and will from time to time hereafter furnish, or cause Northside
Bank to furnish to SouthTrust, upon filing or furnishing the same to the

incurred or paid any obligation or liability which would be material to the
Condition of SBG on a consolidated basis, except as may have been incurred or

respective subsidiaries are, as of the date hereof, parties to any written or
oral: (i) loan agreement, note or borrowing arrangement, other than credit card

payment of principal or interest or, to the knowledge of SBG or Northside Bank,
in default of any other provision as of the date hereof; (ii) loan agreement,
note or borrowing arrangement which has been classified or, in the exercise of

especially mentioned" or any comparable classifications by such persons; (iii)
loan agreement, note or borrowing arrangement, including any loan guaranty,
with any director or executive officer of SBG, Northside Bank or any of their
respective subsidiaries or any ten percent (10%) shareholder of SBG, or any
person, corporation or enterprise controlling, controlled by or under common
control with any of the foregoing; or (iv) loan agreement, note or borrowing
arrangement in violation of any law, regulation or rule applicable to SBG,
Northside Bank or any of their respective subsidiaries including, but not
limited to, those promulgated, interpreted or enforced by any of the Regulatory
Authorities and which violation could have a material adverse effect on the
Condition of SBG on a consolidated basis.  As of the date of any Financial
Statement of SBG, any Financial Statement of Northside Bank and any Call Report
of Northside Bank subsequent to the execution of this Agreement, including the
date of the Financial Statements of SBG, the Financial Statements of Northside
Bank, and the Call Reports of Northside Bank that immediately precede the

         Section 3.6      Authority; No Violation.  (a) SBG has full corporate
power and authority to execute and deliver this Agreement and, subject to the

Regulatory Authorities, to consummate the transactions contemplated hereby.
The Board of Directors of SBG has duly and validly approved this Agreement and
the transactions contemplated hereby, has authorized the execution and delivery
of this Agreement, has directed that this Agreement and the transactions
contemplated hereby be submitted to SBG's shareholders for approval at a
meeting of such shareholders and, except for the adoption of such Agreement by
its shareholders and receipt of the fairness opinion described in Section 9.10,

         Section 5.2      Current Information.  During the period from the date
of this Agreement to the Effective Time of the Merger or the time of
termination or abandonment of this Agreement, SBG will cause one or more of its
designated representatives to confer on a regular and frequent basis with
representatives of SouthTrust and to report the general status of the ongoing
operations of SBG.  SBG will promptly notify SouthTrust of any material change
in the normal course of business or the operations or the properties of SBG,
Northside Bank or any of their respective subsidiaries, any governmental
complaints, investigations or hearings (or communications indicating that the
same may be contemplated) affecting SBG, Northside Bank or their respective
subsidiaries, the institution or the threat of material litigation, claims,
threats or causes of action involving SBG, Northside Bank or any of their
respective subsidiaries, and will keep SouthTrust fully informed of such
events.  SBG will furnish to SouthTrust, promptly after the preparation and/or
receipt by SBG thereof, copies of its unaudited periodic financial statements
and call reports for the applicable periods then ended, and such financial
statements and call reports shall, upon delivery to SouthTrust, be treated, for
purposes of Section 3.3 hereof, as among the Financial Statements of SBG, the
Financial Statements of Northside Bank and the Call Reports of Northside Bank.

         Section 5.3      Access to Properties; Personnel and Records.  (a) So
long as this Agreement shall remain in effect, SBG, Northside Bank and their
respective subsidiaries, shall permit SouthTrust or its agents full access,
during normal business hours, to the properties of SBG, Northside Bank and
their respective subsidiaries, and shall disclose and make available (together
with the right to copy) to SouthTrust and to its internal auditors, loan review
officers, attorneys, accountants and other representatives, all books, papers
and records relating to the assets, stock, properties, operations, obligations
and liabilities of SBG, Northside Bank or their respective subsidiaries,
including all books of account (including the general ledger), tax records,
minute books of directors' and shareholders' meetings, organizational
documents, bylaws, contracts and agreements, filings with any regulatory
agency, examination reports, correspondence with regulatory or taxing
authorities, documents relating to assets, titles, abstracts, appraisals,
consultant's reports, plans affecting employees, securities transfer records
and stockholder lists, and any other assets, business activities or prospects
in which SouthTrust may have a reasonable interest, and SBG, Northside Bank and
their respective subsidiaries shall use their reasonable best efforts to
provide SouthTrust and its representatives access





                                      A-25
<PAGE>   32
to the work papers of SBG's, Northside Bank's and their respective
subsidiaries' accountants.  SBG, Northside Bank and their respective
subsidiaries shall not be required to provide access to or to disclose
information where such access or disclosure would violate or prejudice the
rights of any customer, would contravene any law, rule, regulation, order or
judgment or would violate any confidentiality agreement; provided that SBG,
Northside Bank and their respective subsidiaries shall cooperate with
SouthTrust in seeking to obtain Consents from appropriate parties under whose
rights or authority access is otherwise restricted.  The foregoing rights
granted to SouthTrust shall not, whether or not and regardless of the extent to
which the same are exercised, affect the representations and warranties made in
this Agreement by SBG, Northside Bank or their respective subsidiaries.

                 (b)      As long as this Agreement shall remain in effect,
SouthTrust and ST-Sub shall permit SBG or its agents reasonable access, during
normal business hours, to such of the properties of SouthTrust and ST-Sub, and
shall disclose and make available (together with the right to copy) to SBG and
to its attorneys, accountants and other representatives, documents, bylaws,
contracts and agreements, filings with any regulatory agency, examination
reports, correspondence with regulatory or taxing authorities and such other
materials as, in light of the structure of the transactions contemplated by
this Agreement, including the relative sizes of SouthTrust and SBG, are
customary and reasonable under the circumstances.  Without limiting the
foregoing, SouthTrust shall not be required to provide access to or to disclose
information where such access or disclosure would violate or prejudice the
rights of any customer, would contravene any law, rule, regulation, order or
judgement or would violate any confidentiality agreement.  The foregoing rights
granted to SBG shall not, whether or not and regardless of the extent to which
the same are exercised, affect the representations and warranties made in this
Agreement by SouthTrust and ST-Sub.

                 (c)      All information furnished by the parties hereto
pursuant to this Agreement shall be treated as the sole property of the party
providing such information until the consummation of the Merger contemplated
hereby and, if such transaction shall not occur, the party receiving the
information shall return to the party which furnished such information, all
documents or other materials containing, reflecting or referring to such
information, shall use its best efforts to keep confidential all such
information, and shall not directly or indirectly use such information for any
competitive or other commercial purposes.  The obligation to keep such
information confidential shall continue for two (2) years from the date the
proposed transactions are abandoned but shall not apply to (i) any information
which (A) the party receiving the information was already in possession of
prior to disclosure thereof by the party furnishing the information, (B) was
then available to the public, or (C) became available to the public through no
fault of the party receiving the information; or (ii) disclosures pursuant to a
legal requirement or in accordance with an order of a court of competent
jurisdiction or regulatory agency; provided that the party which is the subject
of any such legal requirement or order shall use its best efforts to give the
other party at least ten (10) business days prior notice thereof.  Each party
hereto acknowledges and agrees that a breach of any of their respective
obligations under this Section 5.3 would cause the other irreparable harm for
which there is no adequate remedy at law, and that, accordingly, each is
entitled to injunctive and other equitable relief for the enforcement thereof
in addition to damages or any other relief available at law.

         Section 5.4      Approval of SBG Shareholders.  SBG will take all
steps necessary under applicable laws to call, give notice of, convene and hold
a meeting of its shareholders at such time as may be mutually agreed to by the
parties for the purpose of approving this Agreement and the transactions
contemplated hereby and for such other purposes consistent with the complete
performance of this Agreement as may be necessary or desirable.  Subject to the
receipt of the fairness opinion described in Section 9.10 hereof (if not
waived), the Board of Directors of SBG will recommend to its shareholders the
approval of this Agreement and the transactions contemplated hereby and SBG
will use its best efforts to obtain the necessary approvals by its shareholders
of this Agreement and the transactions contemplated hereby.

         Section 5.5      No Other Bids.  SBG, acting through any director or
officer or other agent shall not now, nor shall it knowingly permit any of its
subsidiaries to, nor shall it authorize or knowingly permit any officer,
director or employee of, or any investment banker, attorney, accountant or
other representative retained by SBG, Northside Bank or any of their respective
subsidiaries, to solicit or encourage, including by way of furnishing
information, any inquiries or the making of any proposal which may reasonably
be expected to lead to any takeover proposal with respect to SBG, Northside
Bank or any of their respective subsidiaries; provided, however, that the board
of directors of SBG may furnish information to any person making a takeover
proposal, and may discuss such takeover proposal with such person, if the board
of directors has been advised by counsel that its failure to do so would
violate its fiduciary duties.  SBG shall promptly advise SouthTrust orally and
in writing of any such inquiries or proposals





                                      A-26
<PAGE>   33
received by SBG, Northside Bank or any of their respective subsidiaries after
the date hereof.  As used in this Section 5.5, "takeover proposal" shall mean
any proposal for a merger or other business combination involving SBG,
Northside Bank or any of their respective subsidiaries or for the acquisition
of a significant equity interest in SBG, Northside Bank or any of their
respective subsidiaries or for the acquisition of a significant portion of the
assets of SBG, Northside Bank or any of their respective subsidiaries.

         Section 5.6      Notice of Deadlines.  SBG shall notify SouthTrust in
writing of any deadline to exercise an extension or termination of any material
lease, agreement or license (including specifically real property leases and
data processing agreements) to which SBG, Northside Bank or any of their
respective subsidiaries is a party, at least ten (10) days prior to such
deadline.

         Section 5.7      Affiliates.  At least thirty (30) days prior to the

identifying all persons who are, at the time this Agreement is submitted for
approval to the shareholders of SBG, "affiliates" of SBG for purposes of Rule
145 under the Securities Act of 1933.  SBG shall use all reasonable efforts to
cause each person who is identified as an "affiliate" in the letter referred to
above to deliver to SouthTrust not later than thirty (30) days or prior to the
Effective Time of the Merger, a written agreement, providing that such person
will not sell, pledge, transfer, or otherwise dispose of the SBG Shares held by
such person except as contemplated by such written agreement or by this
Agreement and will not sell, pledge, transfer, or otherwise dispose of the
SouthTrust Shares to be received by such person upon consummation of the Merger
except in compliance with applicable provisions of the Securities Act of 1933,
and the rules and regulations thereunder and until such time as the financial
results covering at least thirty (30) days of combined operations of SouthTrust
and SBG have been published within the meaning of Section 201.01 of the SEC's
Codification of Financial Reporting Policies.  If the Merger will qualify for
pooling-of-interests accounting treatment, the SouthTrust Shares issued to such
affiliates of SBG in exchange for the SBG Shares shall not be transferable
until such time as the financial results covering at least thirty (30) days of
combined operations of SouthTrust and SBG have been published within the
meaning of Section 201.01 of the SEC's Codification of Financial Reporting
Policies regardless of whether each such person has provided the written
agreement referred to in this Section 5.7.  SouthTrust shall not be
required to maintain the effectiveness of the Registration Statement under the
Securities Act of 1933 for the purposes of resale of SouthTrust Shares by such
persons.

         Section 5.8      Maintenance of Properties.  SBG, Northside Bank and

made at least 60 days prior to the Effective Time of the Merger, SBG will, at
SouthTrust's expense, with respect to each parcel of real property that SBG,
Northside Bank or any of their respective subsidiaries owns, leases or
subleases, procure and deliver to SouthTrust, at least thirty (30) days prior
to the Effective Time of the Merger, a Phase I environmental audit, which audit
shall be reasonably acceptable to and shall be conducted by a firm reasonably
acceptable to SouthTrust.

         Section 5.10     Title Insurance.  At the election of SouthTrust made
at least 60 days prior to the Effective Time of the Merger, SBG will, at

to the Effective Time of the Merger, owner's title insurance issued in such
amounts and by such insurance company reasonably acceptable to SouthTrust,
which policy shall be free of all material exceptions to SouthTrust's
reasonable satisfaction.

         Section 5.11     Surveys.  At the election of SouthTrust made at least
60 days prior to the Effective Time of the Merger, with respect to each parcel
of real property as to which a title insurance policy is to be procured

deliver to SouthTrust at least thirty (30) days prior to the Effective Time of
the Merger, a survey of such real property, which survey shall be reasonably
acceptable to and shall be prepared by a licensed surveyor reasonably
acceptable to SouthTrust, disclosing the locations of all improvements,
easements, sidewalks, roadways, utility lines and other matters customarily
shown on such surveys and showing access affirmatively to public streets and
roads and providing the legal description of the property in a form suitable

         Section 5.12     Compliance Matters.  Prior to the Effective Time of
the Merger, SBG shall take, or cause to be taken, all steps reasonably
requested by SouthTrust to cure any deficiencies in regulatory compliance by

SouthTrust nor ST-Sub shall be responsible for discovering or have any
obligation to disclose the existence of such defects to SBG nor shall
SouthTrust or ST-Sub have any liability resulting from such deficiencies or
attempts to cure them.

         Section 5.13     Exemption Under Anti-Takeover Statutes.  Prior to the
Effective Time of the Merger, SBG will use its best efforts to take all steps,
if any, required to exempt the transactions contemplated by this Agreement from

Time of the Merger, ST-Bank and Northside Bank shall have executed and
delivered the Subsidiary Merger Agreement substantially in the form annexed

         Section 6.1      Best Efforts; Cooperation.  Subject to the terms and
conditions herein provided, each of the parties hereto agrees to use its best
efforts promptly to take, or cause to be taken, all actions and to do, or cause
to be done, all things necessary, proper or advisable under applicable laws and
regulations, or otherwise, including attempting to obtain all necessary
Consents, to consummate and make effective, as soon as practicable, the
transactions contemplated by this Agreement.

         Section 6.2      Regulatory Matters.  (a)  Following the execution and
delivery of this Agreement, SouthTrust and SBG shall cause to be prepared and
filed all required applications and filings with the Regulatory Authorities
which are necessary or contemplated for the obtaining of the Consents of the
Regulatory Authorities or consummation of the Merger.  Such applications and
filings shall be in such form as may be prescribed by the respective government
agencies and shall contain such information as they may require.  The parties
hereto will cooperate with each other and use their best efforts to prepare and
execute all necessary documentation, to effect all necessary or contemplated
filings and to obtain all necessary or contemplated permits, consents,
approvals, rulings and authorizations of government agencies and third parties
which are necessary or contemplated to consummate the transactions contemplated
by this Agreement, including, without limitation, those required or

Each of the parties shall have the right to review and approve in advance,
which approval shall not be unreasonably withheld, any filing made with, or
written material submitted to, any government agencies in connection with the
transactions contemplated by this Agreement.

                 (b)      Each party hereto will furnish the other party with
all information concerning itself, its subsidiaries, directors, trustees,
officers, shareholders and depositors, as applicable, and such other matters as

Upon request, the parties hereto will promptly furnish each other with copies
of written communications received by them or their respective subsidiaries
from, or delivered by any of the foregoing to, any governmental body in respect
of the transactions contemplated hereby.

         Section 6.3      Other Matters.  (a)  The parties acknowledge that
nothing in this Agreement shall be construed as constituting an employment
agreement between SouthTrust or any of its affiliates and any officer or
employee of SBG, Northside Bank or any of their respective subsidiaries or an
obligation on the part of SouthTrust or any of its affiliates to employ any
such officers or employees, except that Southtrust agrees that it shall cause
ST-Sub and ST-Bank to assume and be bound by the severance policy of Northside
Bank as set forth in Disclosure Schedule 5.15 attached hereto if any Northside
Bank employees covered by such severance policy are terminated by SouthTrust,
ST-Sub or ST-Bank within one (1) year following the Effective Time of the
Merger; provided, however, that if the severance policy of SouthTrust
contemplates severance payments that are at least comparable





                                      A-28
<PAGE>   35
to those contemplated by the severance policy of Northside Bank, SouthTrust,
prior to the expiration of the one year period, may elect to cover such
Northside Bank employees under SouthTrust's severance policy.

                 (b)      The parties agree that appropriate steps shall be
taken to terminate all employee benefit plans of SBG other than the SBG 401(k)
Plan (the "SBG 401(k) Plan"), as of the Effective Time of the Merger or as
promptly as practicable thereafter.  Following the termination of all such
plans (other than the SBG 401(k) Plan), and subject to Section 6.3(c) hereof,
SouthTrust agrees that the officers and employees of SBG who the Surviving

                          (i)     with respect to SouthTrust's group medical
                 insurance plan, SouthTrust shall credit each such employee for
                 eligible expenses incurred by such employee and his or her
                 dependents (if applicable) under SBG's group medical insurance
                 plan during the current calendar year for purposes of
                 satisfying the deductible provisions under SouthTrust's plan
                 for such current year, and SouthTrust shall waive all waiting
                 periods under said plans for pre-existing conditions; and

                          (ii)  credit for each such employee's past service
                 with SBG, Northside Bank or any of their respective
                 subsidiaries prior to the Effective Time of the Merger ("Past
                 Service Credit") shall be given by SouthTrust to such
                 employees for purposes of:

                                  (1)      determining vacation and sick leave
                          benefits and accruals, in accordance with the
                          established policies of SouthTrust;

                                  (2)      establishing eligibility for
                          participation in and vesting under SouthTrust's
                          employee benefit plans (including welfare and fringe
                          benefit plans), and for purposes of determining the
                          scheduling of vacations and other determinations
                          (including severance pay) which are made based on
                          length of service;provided, however, notwithstanding
                          anything contained in this Agreement to the contrary,
                          past service credit shall not be given to any such
                          employee for purposes of establishing eligibility for
                          participation in the 1990 Discounted Stock Plan of
                          SouthTrust.

         (c)     The parties further agree that the SBG 401(k) Plan will either
be merged into the SouthTrust Corporation Employee's Profit Sharing Plan (the
"ST PS Plan") or terminated effective as of December 31 of the year in which
the Effective Time of the Merger occurs, or, if so elected by SouthTrust, as of
the last day of the plan's first plan year ending after the Effective Time of
the Merger.  The determination as to whether the SBG 401(k) Plan shall be
terminated or merged into the ST PS Plan shall be made by SouthTrust.  From and
after the termination of the SBG 401(k) Plan or the merger of the plan into the
ST PS Plan for purposes of determining eligibility to participate in, and
vesting in accrued benefits under both the ST PS Plan and the SouthTrust
Corporation Revised Retirement Income Plan (the "ST Retirement Plan"),
employment by SBG shall be credited as if it were employment by SouthTrust, but
such service shall not be credited for purposes of determining benefit accrual
under the ST Retirement Plan.

         Section 6.4      Indemnification.  (a) SBG agrees to indemnify, defend
and hold harmless SouthTrust and its subsidiaries, and each of their respective
present and former officers, directors, employees and agents, from and against
all losses, expenses, claims, damages or liabilities to which any of them may
become subject under applicable laws (including, but not limited to, the
Securities Act of 1933 or the Securities Exchange Act of 1934), and will
reimburse each of them for any legal, accounting or other expenses reasonably
incurred in connection with investigating or defending any such actions,
whether or not resulting in liability, insofar as such losses, expenses,
claims, damages or liabilities arise out of or are based upon any untrue
statement or alleged untrue statement of material fact supplied to SouthTrust
by SBG or Northside Bank and contained in the Proxy Statement or any
application for the approval of the transactions contemplated by this Agreement
filed with any Regulatory Authority or arise out of or are based upon the
omission or alleged omission to state therein a material fact necessary to make
the statements therein, in light of the circumstances under which they were
made not misleading.

                 (b)      SouthTrust agrees to indemnify, defend and hold
harmless SBG and its subsidiaries and each of their present and former
officers, directors, employees and agents from and against all losses,
expenses, claims, damages or liabilities to which any of them may become
subject under applicable laws (including, but not

<PAGE>   36
limited to, the Securities Act of 1933 or the Securities Exchange Act of 1934),
and will reimburse each of them for any legal, accounting or other expenses
reasonably incurred in connection with investigating or defending any such
actions, whether or not resulting in liability, insofar as such losses,
expenses, claims, damages or liabilities arise out of or are based upon any
untrue statement or alleged untrue statement of material fact supplied by
SouthTrust and contained in the Registration Statement, the Proxy Statement or
any application for the approval of the transactions contemplated by this
Agreement filed with any Regulatory Authority or arise out of or are based upon
the omission by SouthTrust or alleged omission by SouthTrust to state therein a
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

                 (c)      With respect to any claim made or action commenced
within six (6) years after the Effective Time of the Merger, SouthTrust shall
indemnify and hold harmless to the extent permitted by the provisions of the
Articles of Incorporation and Bylaws of SBG and Northside Bank, each as in
effect as of the date hereof, each director, officer, and employee of SBG and
Northside Bank against any costs or expenses (including attorneys fees),

capacity as such, provided, however, that the aggregate amount of such
indemnification shall not exceed $3,000,000, and that such indemnification
shall be to the fullest extent permitted by applicable Georgia law.

directors, officers and employees of SBG and Northside Bank who become or serve
as directors, officers or employees of SouthTrust, ST-Bank or any affiliate of
SouthTrust shall have indemnification rights having prospective application
only, except as set forth in (c) above and except to the extent that (a) above
is applicable.  These prospective indemnification rights shall consist of such
rights to which directors, officers and employees of subsidiaries or affiliates
of SouthTrust would be entitled under the Certificate or Articles of
Incorporation or Association and Bylaws of the particular subsidiary for which
they are serving as directors, officers or employees, the Restated Certificate
of Incorporation and Bylaws of SouthTrust, and such directors and officers

requirements of the Securities Act of 1933 and the general rules and
regulations of the SEC under the Securities Act of 1933.  The Registration
Statement shall include the form of Proxy Statement for the meeting of SBG's
shareholders to be held for the purpose of having such shareholders vote upon
the approval of this Agreement.  SBG will furnish to SouthTrust the information
required to be included in the Registration Statement with respect to its
business and affairs before it is filed with the SEC and again before any
amendments are filed.  SouthTrust shall take all actions required to qualify or
obtain exemptions from such qualifications for the SouthTrust Shares to be
issued in connection with the transactions contemplated by this Agreement under
applicable state blue sky securities laws, as appropriate.

issuance such number of SouthTrust Shares as shall be necessary (i) to pay the
holders of SBG Shares the consideration contemplated in this Agreement and (ii)
to comply with the provisions of Section 2.2(b).  If at any time the aggregate
number of SouthTrust Shares remaining unissued (or in treasury) shall not be
sufficient to meet such obligation, SouthTrust shall take all appropriate
actions to increase the amount of its authorized common stock.

and warranties of SBG set forth in this Agreement and in any certificate or
document delivered pursuant hereto shall be true and correct in all material
respects as of the date of this Agreement and as of all times up to and
including the Effective Time of the Merger (as though made on and as of the
Effective Time of the Merger except to the extent such representations and
warranties are by their express provisions made as of a specified date and
except for changes therein contemplated by this Agreement).

         Section 8.2      Performance of Obligations.  SBG shall have performed
all covenants, obligations and agreements required to be performed by it under
this Agreement prior to the Effective Time of the Merger.

         Section 8.3      Certificate Representing Satisfaction of Conditions.
SBG shall have delivered to SouthTrust and ST-Sub a certificate of SBG dated as
of the Closing Date as to the satisfaction of the matters described in Sections
8.1 and 8.2 hereof, and such certificate shall be deemed to constitute
additional representations, warranties, covenants, and agreements of SBG under
Article III of this Agreement.

         Section 8.4      Absence of Adverse Facts.  No fact, event or
condition exists or has occurred that, in the reasonable judgment of
SouthTrust, (a) would have a material adverse effect on, or which may be
foreseen to have a material adverse effect on, the Condition of SBG on a
consolidated basis or the consummation of the transactions contemplated by this
Agreement, or (b) would be of such significance with respect to the business or
economic benefits expected to be obtained by SouthTrust pursuant to this
Agreement as to render inadvisable the consummation of the transactions
pursuant to this Agreement, provided, however, that any change in the last
sales





                                      A-31
<PAGE>   38
price of the SouthTrust Shares, as reported by Nasdaq, shall not be taken into
account in determining whether any fact, event or condition described in this
Section 8.4(b) has occurred, (c) would be materially adverse to the interests
of SouthTrust on a consolidated basis or (d) would render the Merger or the
other transactions contemplated by this Agreement impractical because of any
state of war, national emergency, banking moratorium or general suspension of
trading on NASDAQ, the New York Stock Exchange, Inc. or other national
securities exchange.

         Section 8.5      Opinion of Counsel.  SouthTrust shall have received
an opinion of counsel from Glass, McCullough, Sherrill & Harrold or other
counsel to SBG acceptable to SouthTrust in substantially the form set forth in

Regulatory Authorities) whose consent or approval shall be required in order to
permit the succession by the Surviving Corporation to any obligation, right or
interest of SBG under any loan or credit agreement, note, mortgage, indenture,
lease, license, or other agreement or instrument, except those for which
failure to obtain such consents and approvals would not in the opinion of
SouthTrust, individually or in the aggregate, have a material adverse effect on
the Surviving Corporation or upon the consummation of the transactions
contemplated by this Agreement.

         Section 8.7      Material Condition.  There shall not be any action
taken, or any statute, rule, regulation or order enacted, entered, enforced or
deemed applicable to the Merger by any Regulatory Authority which, in

in the reasonable judgment of SouthTrust, any material adverse requirement upon
SouthTrust or its subsidiaries, including, without limitation, any requirement
that SouthTrust sell or dispose of any significant amount of the assets of SBG
or any other banking or other subsidiary of SouthTrust, provided that, except
for any such requirement relating to the above-described sale or disposition of
any significant assets of SBG or any banking or other subsidiary of SouthTrust,
no such term or condition imposed by any Regulatory Authority in connection
with the grant of any Consent by any Regulatory Authority shall be deemed to be
a material adverse requirement unless it materially differs from terms and
conditions customarily imposed by any such entity in connection with the
acquisition of banks and bank holding companies under similar circumstances.

         Section 8.8      Matters Relating to Employment Agreements.  Except as
described in Section 6.3(a) above, all employment agreements between SBG,
Northside Bank, any of their respective subsidiaries and any executive or
employee thereof shall be terminated in their entirety as of the Effective Time
of the Merger, and at the election of SouthTrust, replacement employment
agreements, which are satisfactory to SouthTrust and such employees, between
each of such executives or employees and SouthTrust or the Surviving
Corporation shall have been executed and delivered.

         Section 8.9      Acknowledgment of Option Conversion.  Each holder of
a SBG Option outstanding immediately prior to the Effective Time of the Merger

may deem necessary to evidence the assumption by SouthTrust of the SBG Options
as contemplated in and provided for by Section 2.2 hereof.

         Section 8.10     Outstanding Shares of SBG.  The total number of SBG
Shares outstanding as of the Effective Time of the Merger and the total number
of SBG Shares covered by any option, warrant, commitment, or other right or
instrument to purchase or acquire any SBG Shares that are outstanding as of the
Effective Time of the Merger, including any securities or rights convertible
into or exchangeable for SBG Shares, shall not exceed 1,925,994 shares in the
aggregate.

is subject to each of the following conditions, unless waived as hereinafter
provided for:

         Section 9.1      Representations and Warranties.  The representations
and warranties of SouthTrust and ST-Sub contained in this Agreement or in any
certificate or document delivered pursuant to the provisions hereof will be
true and correct as of the date of this Agreement and as of all times up to and
including the Effective Time of the Merger (as though made on and as of the
Effective Time of the Merger).

         Section 9.2      Performance of Obligations.  SouthTrust and ST-Sub
shall have performed all covenants, obligations and agreements required to be
performed by them and under this Agreement prior to the Effective Time of the
Merger.

         Section 9.3      Certificate Representing Satisfaction of Conditions.
SouthTrust and ST-Sub shall have delivered to SBG a certificate of SouthTrust
and ST-Sub dated as of the Effective Time of the Merger as to the satisfaction
of the matters described in Sections 9.1 and 9.2 hereof, and such certificate
shall be deemed to constitute additional representations, warranties,
covenants, and agreements of SouthTrust and ST-Sub under Article IV of this
Agreement.

         Section 9.4      Absence of Adverse Facts.  No fact, event or
condition exists or has occurred that, in the reasonable judgment of SBG, (a)
would have a material adverse effect on, or which may be foreseen to have a
material adverse effect on, the Condition of SouthTrust or the consummation of
the transactions contemplated by this Agreement, or (b) would render the Merger
or the other transactions contemplated by this Agreement impractical because of
any state of war, national emergency, banking moratorium, or a general
suspension of trading on NASDAQ, the New York Stock Exchange, Inc. or other
national securities exchange.

         Section 9.5      Consents Under Agreements.  SouthTrust and ST-Sub
shall have obtained the consent or approval of each person (other than the
Consents of Regulatory Authorities) whose consent or approval shall be required
in connection with the transactions contemplated hereby including under any
loan or credit agreement, note, mortgage, indenture, lease, license or other
agreement or instrument, except those for which failure to obtain such consents
and approvals would not, in the opinion of SBG, individually or in the
aggregate, have a material adverse effect upon the consummation of the
transactions contemplated hereby.

         Section 9.6      Opinion of Counsel.  SBG shall have received the
opinion of Bradley, Arant, Rose & White, counsel to SouthTrust, dated the
Effective Time of the Merger, to the effect set forth in Exhibit 9.6 hereof.

         Section 9.7      SouthTrust Shares.  The SouthTrust Shares to be

Glass, McCullough, Sherrill & Harrold or SBG's independent public accountants,
on or before the date on which the Proxy Statement of SBG is to be mailed to
holders of SBG Shares, to the effect, among others, that the Merger will
constitute a reorganization within the meaning of Section 368 of the Code and
that no gain or loss will be recognized by the shareholders of SBG to the
extent that they receive SouthTrust Shares in exchange for their SBG Shares in
the Merger.

         Section 9.9      Price of SouthTrust Shares.  The average last sale
price of the SouthTrust Shares to be issued in connection herewith, as reported
by NASDAQ for the twenty (20) trading days immediately preceding the Effective
Time of the Merger and the last sales price as reported by Nasdaq for the last
trading day immediately preceding the Effective Time of the Merger, shall not
be less than $16.00 per SouthTrust Share, subject to appropriate adjustment for
the events described in Section 2.1 above, unless SouthTrust, in its sole
discretion, adjusts the Conversion Ratio so that the product of the Conversion
Ratio times the lower of such average sales price or such sales price on the
trading day immediately preceding the Effective Time of the Merger equals
8.441064.

         Section 9.10     Fairness Opinion.  The Board of Directors of SBG
shall have received an opinion, dated not more than five (5) business days
prior to the date of the Proxy Statement of SBG to be mailed to the
shareholders of SBG for purposes of considering and voting upon the Merger,
from an investment banker or bank consultant





                                      A-33

acceptable to SBG that the consideration to be received by the shareholders of
SBG in the Merger is fair to the shareholders of SBG from a financial point of
view.


                                   ARTICLE X

                       TERMINATION, WAIVER AND AMENDMENT


         Section 10.1     Termination.  This Agreement may be terminated and
the Merger abandoned at any time prior to the Effective Time of the Merger:

                 (a)      by the mutual consent in writing of SouthTrust and 
SBG; or

                 (b)      by SouthTrust or SBG if the Merger shall not have
occurred on or prior to September 30, 1995, provided that the failure to
consummate the Merger on or before such date is not caused by any breach of any
of the representations, warranties, covenants or other agreements contained
herein by the party electing to terminate pursuant to this Section 10.1(b);

                 (c)      by SouthTrust or SBG (provided that the terminating
party is not then in breach of any representation, warranty, covenant or other
agreement contained herein) in the event that any of the conditions precedent
to the obligations of the nonterminating party to consummate the Merger cannot
be satisfied or fulfilled;

                 (d)      by SouthTrust if:  (i) SouthTrust shall have
determined that any fact, event or condition exists that, in the reasonable
judgment of SouthTrust, (A) is materially at variance with any warranty or
representation of SBG, Northside Bank or any of their respective subsidiaries
set forth in the Agreement or is a material breach of any covenant or agreement
of SBG, Northside Bank or any of their respective subsidiaries contained in the
Agreement, (B) has a material adverse effect or can be reasonably foreseen to
have a material adverse effect upon the Condition of SBG on a consolidated
basis or upon the consummation of the transactions contemplated by the
Agreement, (C) would be materially adverse to the interests of SouthTrust and
ST-Sub on a consolidated basis, (D) would be of such significance with respect
to the business or economic benefits expected to be obtained by SouthTrust
under this Agreement so as to render inadvisable consummation of the
transactions contemplated by the Agreement, provided, however, that any change
in the last sales price of SouthTrust Shares, as reported by Nasdaq, shall not
be deemed a fact, event or condition that gives rise to any right of
termination under this Section 10.1(d)(i)(D), (E) renders the Merger or the
other transactions contemplated by this Agreement impractical because of any
state of war, national emergency, banking moratorium or general suspension of
trading on NASDAQ, the New York Stock Exchange, Inc. or any other national
securities exchange; or (ii) there shall be any litigation or threat of
litigation (A) challenging the validity or legality of this Agreement or the
consummation of the transactions contemplated by this Agreement, (B) seeking
damages in connection with the consummation of the transactions contemplated by
this Agreement or (C) seeking to restrain or invalidate the consummation of the
transactions contemplated by this Agreement.

                 (e)      by SBG if (i) SBG shall have determined that any
fact, event or condition exists that, in the reasonable judgment of SBG, (A) is
materially at variance with any warranty or representation of SouthTrust or
ST-Sub contained in the Agreement or is a material breach of any covenant or
agreement of SouthTrust of ST-Sub contained in the Agreement, (B) has a
material adverse effect or can be reasonably seen to have a material adverse
effect upon the consummation of the transactions contemplated by the Agreement,
(ii) there shall be any litigation or threat of litigation (A) challenging the
validity or legality of this Agreement or the consummation of the transactions
contemplated by this Agreement, (B) seeking damages in connection with the
consummation of the transactions contemplated by this Agreement or (C) seeking
to restrain or invalidate the consummation of transactions contemplated by this
Agreement, or (iii) SBG shall have determined that any fact, event or condition
exists that, in the judgment of SBG, would render the Merger and the other
transactions contemplated by this Agreement impractical because of any state of
war, national emergency, banking moratorium or general suspension of trading on
NASDAQ, the New York Stock Exchange, Inc. or other national securities
exchange.

         Section 10.2     Effect of Termination.  In the event of the
termination and abandonment of this Agreement as herein provided, it shall
terminate as herein provided and become void, without liability on behalf of
any party, and have no effect, except as otherwise provided herein.

         Section 10.3     Amendments.  To the extent permitted by law, this
Agreement may be amended by a subsequent writing signed by each of SouthTrust,
ST-Sub and SBG.

         Section 10.4     Waivers.  Subject to Section 11.10 hereof, prior to
or at the Effective Time of the Merger, SouthTrust and ST-Sub, on the one hand,
and SBG, on the other hand, shall have the right to waive any default in the
performance of any term of this Agreement by the other, to waive or extend the
time for the compliance or fulfillment by the other of any and all of the
other's obligations under this Agreement and to waive any or all of the
conditions to its obligations under this Agreement, except any condition,
which, if not satisfied, would result in the violation of any law or any
applicable governmental regulation.

         Section 10.5     Non-Survival of Representations and Warranties.  No
representations, warranties, covenants or agreements in this Agreement or in
any instrument delivered by SouthTrust, ST-Sub or SBG shall survive the
Effective Time of the Merger or the termination of this Agreement pursuant to
Section 10.1; provided, however, that the agreements set forth in Articles I
and II, Sections 5.7, 6.3, 6.4 and 10.2 and Article XI shall not so terminate
and shall not be so extinguished; provided further that any representation or
warranty in any agreement, contract, report, opinion, undertaking or other
document or instrument delivered hereunder in whole or in part by any person
other than SouthTrust, ST-Sub, SBG or Northside Bank (or directors and officers
thereof in their capacities as such) shall not so terminate and shall not be so
extinguished; and provided further, that no representation or warranty of
SouthTrust, ST-Sub, SBG or Northside Bank contained herein shall be deemed to
be terminated or extinguished so as to deprive SouthTrust or ST-Sub, on the one
hand, and SBG or Northside Bank, on the other hand, of any defense at law or in
equity which any of them otherwise would have to any claim against them by any
person, including, without limitation, any shareholder or former shareholder of
either party.  No representation or warranty in this Agreement shall be
affected or deemed waived by reason of the fact that SouthTrust, ST-Sub, SBG or
Northside Bank and/or its representatives knew or should have known that any
such representation or warranty was, or is, inaccurate in any material respect.



                                   ARTICLE XI
