immediately prior to the Effective Time (other than PBC Dissenting Shares (as
defined below) and shares of PBC Common Stock held directly or indirectly by
BancorpSouth or PBC or any of their respective Subsidiaries as defined in
Section 3.2(d) hereof (as adjusted below), other than Trust Account Shares and
DPC shares as such terms are defined in this Section below) shall be converted,
at the election of the holder thereof, into the right to receive the following,
without interest:

         (i) for each share of PBC Common Stock with respect to which an
election to receive cash has been made (a "Cash Election"), the right to receive
in cash an amount equal to $50.07 (the "Cash Consideration", and collectively,
the "Cash Election Shares");

         (ii) for each share of PBC Common Stock with respect to which an
election to receive common stock, par value $2.50 per share, of BancorpSouth
(the "BancorpSouth Common Stock") together with the number of BancorpSouth
Rights (as defined in Section 5.2 hereof) associated therewith, has been made (a
"Stock Election"), the right to receive from BancorpSouth the number of shares
of BancorpSouth Common Stock as is equal to the Exchange Ratio (as defined in
Section 1.4(b)) (the "Stock Consideration"), and (collectively, the "Stock
Election Shares");


                                       2


         (iii) Holders of more than one share of PBC Common Stock may elect a
combination of both cash and shares of BancorpSouth Common Stock (with such
election referred to as a "Mixed Election"). For purposes of this Agreement,
Cash Consideration, Stock Consideration and any combination thereof shall be
collectively referred to herein as "Merger Consideration."; and

         (iv) for each share of PBC Common Stock other than PBC Dissenters'
Shares and shares as to which a Cash Election or a Stock Election has been
effectively made (collectively, "Non-Election Shares"), the right to receive
from BancorpSouth such Stock Consideration and/or Cash Consideration as is
determined in accordance with Section 1.4(d).

         (b) Certain Definitions. For purposes of this Agreement, the following
terms shall have the following meanings:

         (i) "Aggregate BancorpSouth Share Amount" shall be a number of shares
of BancorpSouth Common Stock equal to the number of shares of PBC Common Stock
outstanding at the time of determination multiplied by 1.1111.

         (ii) "Aggregate Cash Election Amount" means the amount calculated by
multiplying the Cash Consideration by the sum of (x) the aggregate number of
Cash Election Shares and (y) the aggregate number of Non-Election Shares being
converted into the right to receive the Cash Consideration.

         (iii) "Exchange Ratio" means 2.1785.

         (c) Subject to Section 1.6, the total number of shares of PBC Common
Stock to be converted into Stock Consideration (the "Stock Conversion Number")
shall be equal to the quotient obtained by dividing (x) the Aggregate
BancorpSouth Share Amount by (y) the Exchange Ratio. All of the other shares of
PBC Common Stock shall be converted into Cash Consideration (in each case,
excluding shares of PBC Common Stock to be cancelled pursuant to Subsection (e)
below).

         (d) As promptly as possible after the Election Deadline (as defined
below), BancorpSouth shall cause the Exchange Agent (as defined in Section 2.1)
to effect the allocation among holders of PBC Common Stock of rights to receive
the Cash Consideration and the Stock Consideration as follows:

         (i) If the aggregate number of shares of PBC Common Stock with respect
to which Stock Elections shall have been made (the "Stock Election Number")
exceeds the Stock Conversion Number, then all Cash Election Shares and all
Non-Election Shares of each holder thereof shall be converted into the right to
receive the Cash Consideration, and Stock Election Shares of each holder thereof
will be converted into the right to receive the Stock Consideration in respect
of that number of Stock Election Shares equal to the product obtained by
multiplying (x) the number of Stock Election Shares held by such holder by (y) a
fraction, the numerator of which is the Stock Conversion Number and the
denominator of which is the Stock Election Number, with the remaining number of
such holder's Stock Election Shares being converted into the right to receive
the Cash Consideration; and

         (ii) If the Stock Election Number is less than the Stock Conversion
Number (the amount by which the Stock Conversion Number exceeds the Stock
Election Number being referred to herein as the "Shortfall Number"), then all
Stock Election Shares shall be converted into the right to receive the Stock
Consideration and the Non-Election Shares and Cash Election Shares shall be
treated in the following manner:

         (A) If the Shortfall Number is less than or equal to the number of
         Non-Election Shares, then all Cash Election Shares shall be converted
         into the right to receive the Cash Consideration and the Non-Election
         Shares of each holder thereof shall convert into the right to receive
         the Stock


                                       3


         Consideration in respect of that number of Non-Election Shares equal to
         the product obtained by multiplying (x) the number of Non-Election
         Shares held by such holder by (y) a fraction, the numerator of which is
         the Shortfall Number and the denominator of which is the total number
         of Non-Election Shares, with the remaining number of such holder's
         Non-Election Shares being converted into the right to receive the Cash
         Consideration; or

         (B) If the Shortfall Number exceeds the number of Non-Election Shares,
         then all Non-Election Shares shall be converted into the right to
         receive the Stock Consideration and Cash Election Shares of each holder
         thereof shall convert into the right to receive the Stock Consideration
         in respect of that number of Cash Election Shares equal to the product
         obtained by multiplying (x) the number of Cash Election Shares held by
         such holder by (y) a fraction, the numerator of which is the amount by
         which (1) the Shortfall Number exceeds (2) the total number of
         Non-Election Shares and the denominator of which is the total number of
         Cash Election Shares, with the remaining number of such holder's Cash
         Election Shares being converted into the right to receive the Cash
         Consideration.

          (e) At the Effective Time, all shares of PBC Common Stock that are
owned directly or indirectly by BancorpSouth or PBC or any of their respective
Subsidiaries, other than shares of PBC Common Stock (i) held directly or
indirectly in trust accounts, managed accounts and the like or otherwise held in
a fiduciary capacity for the benefit of third parties (any such shares, and
shares of BancorpSouth Common Stock which are similarly held, whether held
directly or indirectly by BancorpSouth or PBC, as the case may be, being
referred to herein as "Trust Account Shares") and (ii) held by BancorpSouth or
PBC or any of their respective Subsidiaries in respect of a debt previously
contracted (any such shares of PBC Common Stock, and shares of BancorpSouth
Common Stock which are similarly held, whether held directly or indirectly by
BancorpSouth or PBC, being referred to herein as "DPC Shares"), shall be
canceled and shall cease to exist, and no stock of BancorpSouth or other
consideration shall be delivered in exchange therefor. All shares of
BancorpSouth Common Stock that are owned by PBC or any of its Subsidiaries
(other than Trust Account Shares and DPC Shares) shall become treasury stock of
BancorpSouth.

         (f) Each share of PBC Common Stock converted into BancorpSouth Common
Stock pursuant to this Article I shall no longer be outstanding and shall
automatically be canceled and shall cease to exist, and each certificate (each a
"Certificate") previously representing any such shares of PBC Common Stock shall
thereafter only represent the right to receive (i) the number of whole shares of
BancorpSouth Common Stock into which such share is convertible pursuant to
Section 1.4(a) and (ii) the cash in lieu of fractional shares into which the
shares of PBC Common Stock represented by such Certificate have been converted
pursuant to Section 1.4(a) and Section 2.2(e) hereof, and (iii) Cash
Consideration pursuant to Section 1.4(a) hereof. Certificates previously
representing shares of PBC Common Stock shall be exchanged for certificates
representing whole shares of BancorpSouth Common Stock and cash in lieu of
fractional shares issued in consideration therefor and Cash Consideration upon
the surrender of such Certificates in accordance with Section 2.2 hereof,
without any interest thereon. If, between the date of this Agreement and the
Effective Time, the shares of BancorpSouth Common Stock shall be changed into a
different number or class of shares by reason of any reclassification,
recapitalization, split-up, combination, exchange of shares or readjustment, or
a stock dividend thereon shall be declared with a record date within said period
(any such event, an "Anti-Dilution Event"), the Exchange Ratio and the Merger
Consideration shall be adjusted to result in the same aggregate consideration
being delivered to PBC's shareholders as would have been received had such
Anti-Dilution Event not occurred.

         (g) Notwithstanding anything in this Agreement to the contrary, shares
of PBC Common Stock which are outstanding immediately prior to the Effective
Time and with respect to which dissenters' rights shall have been properly
demanded in accordance with Sections 48-23-201, et. seq. of


                                       4


the TBCA ("PBC Dissenting Shares") shall not be converted into the right to
receive, or be exchangeable for, Merger Consideration or cash in lieu of
fractional shares but, instead, the holders thereof shall be entitled to payment
of the appraised value of such PBC Dissenting Shares in accordance with the
provisions of Sections of the TBCA; provided, however, that (i) if any holder of
PBC Dissenting Shares shall subsequently deliver a written withdrawal of his
demand for appraisal of such shares, or (ii) if any holder fails to establish
his entitlement to dissenters' rights as provided in Sections 48-23-202, et.
sec. of the TBCA, such holder or holders (as the case may be) shall forfeit the
right to appraisal of such shares of PBC Common Stock and each of such shares
shall thereupon be deemed to have been converted into the right to receive, and
to have become exchangeable for, as of the Effective Time, Stock Consideration
and/or cash in lieu of fractional shares and/or Cash Consideration, without any
interest thereon, as provided in Sections 1.4(a) and 1.4(c) and Article II
hereof.

         (h) At the Effective Time, all shares of PBB common stock shall be
canceled and shall cease to exist and no stock of BancorpSouth or BancorpSouth
Bank or other consideration shall be delivered in exchange therefor.

1.5 Stock Options. At the Effective Time, each option granted by PBC to purchase
shares of PBC Common Stock which is outstanding and unexercised immediately
prior thereto (each, a "PBC Option") shall, by virtue of the Merger and without
any further action by the holder thereof, cease to represent a right to acquire
shares of PBC Common Stock and shall be considered an option (the "New Option")
issued under and subject to the appropriate stock option plan of BancorpSouth to
purchase shares of BancorpSouth Common Stock to be issued in an amount and at an
exercise price determined as provided below:

         (a) The number of shares of BancorpSouth Common Stock to be subject to
the New Option shall be equal to the number of shares of BancorpSouth Common
Stock to which the holder of the PBC Option would have been entitled under
Section 1.4(a) of this Agreement had the PBC Option been exercised in full
immediately prior to the Effective Time and had such holder received only Stock
Consideration in the Merger, provided that any fractional shares of BancorpSouth
Common Stock resulting from such multiplication shall be rounded to the nearest
whole share; and

         (b) The exercise price per share of BancorpSouth Common Stock under the
New Option shall be equal to the aggregate exercise price for the shares of PBC
Common Stock otherwise purchasable under the PBC Option divided by the number of
shares of BancorpSouth Common Stock issuable under the New Option pursuant to
Section 1.5(a); provided that any such exercise price which would otherwise
include a fraction of a cent shall be rounded to the nearest whole cent. The
adjustment provided herein with respect to any PBC Options which are "incentive
stock options" (as defined in Section 422 of the Code) shall be and is intended
to be effected in a manner which is consistent with Section 424(a) of the Code
and, to the extent it is not so consistent, such Section 424(a) of the Code
shall override anything to the contrary contained herein. The duration of the
New Option shall be the same as the original PBC Option. All New Options shall
be exercisable by the holder thereof in accordance with the terms of the
agreements for the PBC Options.

         (c) At the Effective Time, BancorpSouth shall either adopt the PBC
Option plans for the purpose of issuing New Options or, in BancorpSouth's sole
discretion, issue New Options under and subject to an appropriate stock option
plan of BancorpSouth. At or prior to the Effective Time, BancorpSouth shall take
all corporate action necessary to reserve for issuance a sufficient number of
shares of BancorpSouth Common Stock for delivery upon exercise of the New
Options. At or prior to the Effective Time, BancorpSouth shall take such action
as is necessary to ensure that a registration statement on Form S-8, S-4 or
other applicable form is effective to cover the shares of BancorpSouth Common
Stock subject to the New Options.


                                       5


         1.6 Tax Matters. Notwithstanding any other provision contained in this
Agreement, it is intended that the Holding Company Merger shall qualify as a
reorganization within the meaning of Section 368(a) of the Code and that this
Agreement shall constitute a "plan of reorganization" for purposes of Sections
354 and 361 of the Code.

         (a) In order that the Holding Company Merger will not fail to satisfy
the continuity of interest requirements under applicable federal income tax
principles relating to reorganizations under Section 368(a) of the Code, if the
aggregate value of the shares of BancorpSouth Common Stock to be issued in
connection with the Holding Company Merger, based upon the closing price of
BancorpSouth Common Stock as reported on the NYSE at the end of the regular
session on the business day immediately preceding the Effective Time (the
"Aggregate BancorpSouth Share Value Consideration"), would be less than 45% of
the sum of (i) the Aggregate BancorpSouth Share Value Consideration and (ii) the
Aggregate Cash Value Consideration (as defined below), then BancorpSouth may, in
its sole discretion, increase the Stock Consideration and decrease the Cash
Consideration so that the aggregate value of the shares of BancorpSouth Common
Stock to be issued to the holders of PBC Common Stock in connection with the
Holding Company Merger, as determined based upon the closing price of
BancorpSouth Common Stock as reported on the NYSE at the end of the regular
session on the business day immediately preceding the Effective Time, is equal
to 45% of the sum of (i) the aggregate value of the shares of BancorpSouth
Common Stock to be issued to the holders of PBC Common Stock in connection with
the Holding Company Merger, as determined based upon the closing price of
BancorpSouth Common Stock as reported on the NYSE at the end of the regular
session on the business day immediately preceding the Effective Time, and (ii)
the Aggregate Cash Value Consideration. In the event that the Stock
Consideration and Cash Consideration are adjusted as provided for in this
Section 1.6(a), all references in this Agreement to the "Stock Consideration"
and the "Cash Consideration" shall refer to the Stock Consideration and Cash
Consideration as adjusted in this Section 1.6(a). For purposes of this
Agreement, the "Aggregate Cash Value Consideration" shall be an amount equal to
the sum of (x) Aggregate Cash Election Amount, (y) the product of the number of
PBC Dissenting Shares (except to the extent that the holder of such PBC
Dissenting Shares, as of the Closing Date, has effectively withdrawn or lost his
right to dissent from the Merger under the TBCA) and the Cash Consideration and
(z) any other amounts received by a holder of PBC Common Stock prior to the
Merger, either in a redemption of PBC stock or in a distribution with respect to
PBC stock (but only to the extent such amount is treated as other property or
money received in the exchange for purposes of Section 356 of the Code, or would
be so treated if the PBC shareholder also had received stock of BancorpSouth in
exchange for stock owned by the shareholder in PBC).

         (b) The parties agree that BancorpSouth may at any time change the
method of effecting the combination of BancorpSouth and PBC or the Bank Merger,
including, without limitation, by merging PBC with a direct wholly-owned
subsidiary of BancorpSouth, and PBC shall cooperate in such efforts, including
by entering into an appropriate amendment to this Agreement (to the extent such
amendment only changes the method of effecting the business combination and does
not substantively affect this Agreement or the rights and obligations of the
parties or their respective shareholders hereunder); provided, however, that any
such subsidiary shall become a party to, and shall agree to be bound by, the
terms of this Agreement, and that any such change shall not (i) alter or change
the kind or amount of Merger Consideration to be provided to holders of PBC
Common Stock as provided for in this Agreement, (ii) adversely affect the rights
of holders of PBC Options (hereinafter defined) or (iii) materially impede or
delay consummation of the transactions contemplated by this Agreement.

1.7 BancorpSouth Common Stock. Except for shares of BancorpSouth Common Stock
owned by PBC or any of its Subsidiaries (other than Trust Account Shares and DPC
Shares), which shall be converted into authorized but unissued stock of
BancorpSouth as contemplated by Section 1.4 hereof, the shares of BancorpSouth
Common Stock issued and outstanding


                                       6


immediately prior to the Effective Time shall be unaffected by the Merger and
such shares shall remain issued and outstanding.

1.8 Articles of Incorporation. At the Effective Time, the Amended and Restated
Articles of Incorporation of BancorpSouth, as in effect at the Effective Time,
shall be the articles of incorporation of the Surviving Corporation. At the
Effective Time, the Amended and Restated Articles of Association of BancorpSouth
Bank, as in effect at the Effective Time, shall be the articles of association
of the Surviving Bank.

1.9 Bylaws. At the Effective Time, the Bylaws of BancorpSouth, as in effect
immediately prior to the Effective Time, shall be the bylaws of the Surviving
Corporation until thereafter amended in accordance with applicable law and the
articles of incorporation of the Surviving Corporation. At the Effective Time,
the Bylaws of BancorpSouth Bank, as in effect immediately prior to the Effective
Time, shall be the bylaws of the Surviving Bank until thereafter amended in
accordance with applicable law and the articles of association of the Surviving
Bank.

1.10 Directors and Officers. The directors and officers of BancorpSouth
immediately prior to the Effective Time shall be the directors and officers of
the Surviving Corporation, each to hold office in accordance with the articles
of incorporation and bylaws of the Surviving Corporation until their respective
successors are duly elected or appointed and qualified. The directors and
officers of BancorpSouth Bank immediately prior to the Effective Time shall be
the directors and officers of the Surviving Bank, each to hold office in
accordance with the articles of association and bylaws of the Surviving Bank
until their respective successors are duly elected or appointed and qualified.


                         ARTICLE II. EXCHANGE OF SHARES

2.1 BancorpSouth to Make Shares and Cash Available. At or prior to the Effective
Time, BancorpSouth shall deposit, or shall cause to be deposited, with SunTrust
Bank, Atlanta, N.A. or another bank or trust company (the "Exchange Agent")
selected by BancorpSouth and reasonably satisfactory to PBC, for the benefit of
the holders of Certificates, for exchange in accordance with this Article II,
the Cash Consideration, certificates representing the shares of BancorpSouth
Common Stock constituting the Stock Consideration and the cash in lieu of
fractional shares (such cash and certificates for shares of BancorpSouth Common
Stock, together with any dividends or distributions with respect thereto, being
hereinafter referred to as the "Exchange Fund") to be issued pursuant to Section
1.4 and paid pursuant to Section 2.2(a) in exchange for outstanding shares of
PBC Common Stock.

2.2 Exchange of Shares; Payment of Cash Consideration.

         (a) At the time of the mailing of the Proxy Statement and Prospectus
described in Section 7.1 hereof, BancorpSouth will cause the Exchange Agent to
send to each holder of record of shares of PBC Common Stock on the record date
for the meeting of the shareholders of PBC a letter of transmittal and cash
election form (collectively, the "Election Form") and other appropriate
materials providing for such holder, subject to the provisions of Section 1.4
hereof, to make a Stock Election, Cash Election, Mixed Election, or No Election.
As of the Election Deadline (as defined below), any shares of PBC Common Stock
with respect to which there shall not have been such election by submission to
the Exchange Agent of an effective, properly completed Election Form shall be
deemed to be No Election Shares.


                                       8


                  (i) Any Cash Election, Stock Election or Mixed Election shall
have been validly made only if the Exchange Agent shall have received an
Election Form properly completed by 5:00 p.m., Central Time, on the second
business day immediately preceding the meeting of shareholders of PBC described
in Section 7.1 hereof (the "Election Deadline"). An election by a holder of
shares of PBC Common Stock shall be validly made only if the Exchange Agent
shall have received an Election Form properly completed and executed (with the
signature or signatures thereon guaranteed if required by the Election Form) by
such holder of shares of PBC Common Stock. An Election Form shall be deemed
properly completed only if accompanied by one or more Certificates (or customary
affidavits and, if required by BancorpSouth, indemnification regarding the loss
or destruction of such Certificates or the guaranteed delivery of such
Certificates) representing all shares of PBC Common Stock covered by such
Election Form, together with duly executed transmittal materials included with
the Election Form. BancorpSouth shall have the right to make reasonable
determinations and to establish reasonable procedures (not inconsistent with the
terms of this Agreement) in guiding the Exchange Agent in its determination as
to the validity of Election Forms and of any revision, revocation or withdrawal
thereof.

                  (ii) Two or more holders of shares of PBC Common Stock who are
determined to constructively own shares owned by each other by virtue of Section
318(a) of the Code and who so certify to BancorpSouth's satisfaction, and any
single holder of shares of PBC Common Stock who holds such shares in two or more
different names and who so certifies to BancorpSouth's satisfaction, may submit
a joint Election Form covering the aggregate shares of PBC Common Stock owned by
all such holders or by such single holder, as the case may be. For all purposes
of this Agreement, each such group of holders which, and each such single holder
who, submits a joint Election Form shall be treated as a single holder of shares
of PBC Common Stock.

                  (iii) Each holder of record of shares of PBC Common Stock who
holds such shares as nominee, trustee or in other representative capacities
(each, a "Representative") may submit multiple Election Forms, provided that
such Representative certifies that each such Election Form covers all shares of
PBC Common Stock held by that Representative for a particular beneficial owner.

                  (iv) Any holder of shares of PBC Common Stock who has made an
election by submitting an Election Form to the Exchange Agent may at any time
prior to the Election Deadline change such holder's election by submitting a
revised Election Form, properly completed and signed, that is received by the
Exchange Agent prior to the Election Deadline. Any holder of shares of PBC
Common Stock may at any time prior to the Election Deadline revoke such holder's
election by written notice to the Exchange Agent received at any time prior to
the Election Deadline.

         (b) As soon as practicable after the Election Deadline (the "Allocation
Date"), the Exchange Agent shall effectuate the allocation among the holders of
shares of PBC Common Stock of rights to receive the Stock Consideration, the
Cash Consideration or a combination of both the Stock Consideration and the Cash
Consideration in the Merger in accordance with the terms of this Section. As
more fully set forth in Section 1.4 above, the aggregate number of shares of PBC
Common Stock to be converted in the Merger into the right to receive Cash
Consideration may not exceed 49.0% of the outstanding shares of PBC Common
Stock, and the aggregate number of shares of PBC Common Stock to be converted in
the Merger into the right to receive Stock Consideration may not exceed 51.0% of
the total number of outstanding shares of PBC Common Stock.

         (c) No dividends or other distributions declared after the Effective
Time with respect to BancorpSouth Common Stock and payable to the holders of
record thereof shall be paid to the holder of any unsurrendered Certificate
until the holder thereof shall surrender such Certificate in accordance with
this Article II. After the surrender of a Certificate in accordance with this
Article II, the record holder thereof shall be entitled to receive any such
dividends or other distributions, without any interest thereon,


                                       8


which theretofore had become payable with respect to shares of BancorpSouth
Common Stock represented by such Certificate.

         (d) If any certificate representing shares of BancorpSouth Common Stock
is to be issued in a name other than that in which the Certificate surrendered
in exchange therefor is registered, it shall be a condition of the issuance
thereof that the Certificate so surrendered shall be properly endorsed (or
accompanied by an appropriate instrument of transfer) and otherwise in proper
form for transfer, and that the person requesting such exchange shall pay to the
Exchange Agent in advance any transfer or other taxes required by reason of the
issuance of a certificate representing shares of BancorpSouth Common Stock in
any name other than that of the registered holder of the Certificate
surrendered, or required for any other reason, or shall establish to the
satisfaction of the Exchange Agent that such tax has been paid or is not
payable.

         (e) After the Effective Time, there shall be no transfers on the stock
transfer books of PBC of the shares of PBC Common Stock which were issued and
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates representing such shares are presented for transfer to the
Exchange Agent, they shall be canceled and exchanged for certificates
representing shares of BancorpSouth Common Stock as provided in this Article II.

         (f) Notwithstanding anything to the contrary contained herein, no
certificates or scrip representing fractional shares of BancorpSouth Common
Stock shall be issued upon the surrender for exchange of Certificates, no
dividend or distribution with respect to BancorpSouth Common Stock shall be
payable on or with respect to any fractional share, and such fractional share
interests shall not entitle the owner thereof to vote or to any other rights of
a shareholder of BancorpSouth. In lieu of the issuance of any such fractional
share, BancorpSouth shall pay to each former shareholder of PBC who otherwise
would be entitled to receive a fractional share of BancorpSouth Common Stock an
amount in cash equal to the product of (x) $22.984 and (y) the fraction of a
share of BancorpSouth Common Stock which such holder would otherwise be entitled
to receive pursuant to Article I hereof.

         (g) Any portion of the Exchange Fund that remains unclaimed by the
shareholders of PBC for 12 months after the Effective Time shall be paid to
BancorpSouth. Any shareholders of PBC who have not theretofore complied with
this Article II shall thereafter look only to BancorpSouth for payment of their
portion of the Cash Consideration and their shares of BancorpSouth Common Stock,
cash in lieu of fractional shares and unpaid dividends and distributions on
BancorpSouth Common Stock deliverable in respect of each share of PBC Common
Stock such shareholder holds as determined pursuant to this Agreement, in each
case, without any interest thereon. Notwithstanding the foregoing, none of
BancorpSouth, PBC, the Exchange Agent or any other person shall be liable to any
former holder of shares of PBC Common Stock for any amount properly delivered to
a public official pursuant to applicable abandoned property, escheat or similar
laws.

         (h) In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by
BancorpSouth, the posting by such person of a bond in such amount as is
customarily required by BancorpSouth and Exchange Agent for other shareholders
of BancorpSouth as indemnity against any claim that may be made against it with
respect to such Certificate, the Exchange Agent will issue in exchange for such
lost, stolen or destroyed Certificate the shares of BancorpSouth Common Stock
and cash in lieu of fractional shares deliverable in respect thereof pursuant to
this Agreement.

do business in each jurisdiction in which the nature of the business conducted
by it or the character or location of the properties and assets owned or leased

obtain such license or qualification would not have a Material Adverse Effect on
PBC. PBC is duly registered as a bank holding company under the Bank Holding
Company Act of 1956, as amended (the "BHC Act"). The Charter and Bylaws of PBC,
copies of which have previously been provided to BancorpSouth, are true and
correct copies of such documents as currently in effect. PBC has no Subsidiaries
other than PBB and Premier Bancorp Capital Trust I, which is used as a vehicle

of the PBC Disclosure Schedule), any shares of capital stock or any equity
securities or similar interests of any person, or any interest in a partnership

therewith have been paid when due. PBB has the corporate power and authority to

4.11 Employees.

         (a) Section 4.11(a) of the PBC Disclosure Schedule sets forth a true,
complete and correct list (all of which are collectively referred to as the
"Employee Plans") of all "employee benefit plans" as defined by section 3(3) of
the Employee Retirement Income Security Act of 1974, as amended, and the rules
and regulations promulgated thereunder (collectively, "ERISA"), all specified
fringe benefit plans as defined in section 6039D of the Code, and all other
bonus, incentive compensation, deferred compensation, profit sharing, stock
option, stock appreciation right, stock bonus, stock purchase, employee stock
ownership, savings, severance, supplemental unemployment, layoff, salary
continuation, retirement, pension, health, life insurance, disability, group
insurance, vacation, holiday, sick leave, fringe benefit, or welfare plan, or
employment, consulting, change in control, independent contractor, professional
services, confidentiality, or non-competition agreement or any other similar
plan, agreement, policy or understanding (whether written or oral, qualified or
nonqualified), and any trust, escrow or other agreement related thereto, which
(i) is now or was for the last five (5) years maintained or contributed to by
PBC or an ERISA Affiliate (as hereinafter defined), or (ii) with respect to
which PBC or any ERISA Affiliate has any obligations to any current or former
officer, Employee, service provider, or the dependents of any thereof,
regardless of whether funded, or (iii) which could result in the imposition of
any liability or obligation of any kind or nature, whether accrued, absolute,
contingent, direct, indirect, known or unknown, perfected or inchoate or
otherwise, and whether or not now due or to become due to PBC or any ERISA
Affiliate.

         (b) PBC has heretofore provided to BancorpSouth, to the extent
requested by BancorpSouth, and with respect to each of the Employee Plans, true
and correct copies of each of the following documents, as applicable: (i) the
Employee Plan document, (ii) the actuarial report, if any, for such Employee
Plan for each of the last three (3) years, (iii) the most recent determination
letter from the IRS for such Employee Plan, (iv) the IRS Form 5500 annual
reports for such Employee Plan for each of the last three (3) years, and (v) the
most recent summary plan description and related summaries of material
modifications.

         (c) Neither PBC nor any ERISA Affiliate has been liable at any time for
contributions to a Plan that is subject to section 412 of the Code, section 302
of ERISA and/or Title IV of ERISA.

         (d) The form and operation of all Employee Plans is in compliance with
the applicable terms of ERISA, the Code, and any other applicable laws,
including the Americans with Disabilities Act of


                                       16



1990, the Family Medical Leave Act of 1993 and the Health Insurance Portability
and Accountability Act of 1996, and such Employee Plans have been operated in
compliance with such laws and the written Employee Plan documents. Neither PBC
nor any fiduciary of an Employee Plan has violated the requirements of section
404 of ERISA. All required reports and descriptions of the Employee Plans
(including Internal Revenue Service Form 5500 Annual Reports, Summary Annual
Reports and Summary Plan Descriptions and Summaries of Material Modifications)
have been (when required) timely filed with the IRS and the United States
Department of Labor (the "DOL") and distributed as required to all participants
and beneficiaries, and all notices required by ERISA or the Code with respect to
the Employee Plans have been appropriately given. There have been no prohibited
transactions with respect to the Employee Plans.

         (e) Each Employee Plan that is intended to be qualified under section
401(a) of the Code has received a favorable determination letter from the IRS,
and neither PBC nor ERISA Affiliate has any knowledge of any circumstances that
will or could result in revocation of any such favorable determination letter.
Each trust created under any Employee Plan has been determined to be exempt from
taxation under section 501(a) of the Code, and PBC is not aware of any
circumstance that will or could result in a revocation of such exemption. Each
Employee Plan that is an employee welfare benefit plan (as defined in section
3(1) of ERISA) that utilizes a funding vehicle described in section 501(c)(9) of
the Code or is subject to the provisions of section 505 of the Code has been the
subject of a notification by the IRS that such funding vehicle qualifies for
tax-exempt status under section 501(c)(9) of the Code or that the Employee Plan
complies with section 505 of the Code, unless the IRS does not, as a matter of
policy, issue such notification with respect to the particular type of plan.
With respect to each Employee Plan, no event has occurred or condition exists
that will or could give rise to a loss of any intended tax consequence or to any
tax under section 511 of the Code.

         (f) There are no pending claims, lawsuits or actions relating to any
Employee Plan (other than ordinary course claims for benefits) and, to the best
knowledge of PBC, none are threatened.

         (g) No written or oral representations have been made to any Employee
or former Employee of PBC or any ERISA Affiliate promising or guaranteeing any
employer payment or funding, and no Employee Plans provide, for the continuation
of medical, dental, life or disability insurance coverage for any former
Employee of PBC or any ERISA Affiliate for any period of time beyond the end of
the current plan year (except to the extent of coverage required under Title I,
Part 6, of ERISA).

         (h) Except for the possibility of full vesting of Code section 401(a)
plan account balances which may be necessitated by Code section 411(d)(3) in
order for tax-qualified status to be retained, the consummation of the
transactions contemplated by this Agreement will not accelerate the time of
vesting, of payment, or increase the amount, of compensation to any Employee,
officer, former Employee or former officer of PBC or any ERISA Affiliate. Except
as set forth in Section 4.11(h) of the PBC Disclosure Schedule, no wages,
salaries, compensation, bonus, pension or other payments to any employee,
affiliate, officer, director or broker of PBC or PBB will be triggered by or
result from the consummation of the transactions contemplated by this Agreement.
No Employee Plan or other contracts or arrangements, including those
contemplated in this Agreement, provide for payments or other benefits that
would be triggered by the consummation of the transactions contemplated by this
Agreement that would subject any person to excise tax under section 4999 of the
Code (i.e., "golden parachute" taxes). All compensation amounts that have been
paid or are payable are or will become deductible by PBC or BancorpSouth
pursuant to section 162 of the Code.

         (i) PBC and each ERISA Affiliate have at all times complied and
currently comply in all material respects with the applicable continuation
requirements for their welfare benefit plans, including (1) section 4980B of the
Code (as well as its predecessor provision, section 162(k) of the Code) and
sections 601 through 608, inclusive, of ERISA, which provisions are hereinafter
referred to collectively as


                                       17



"COBRA" and (2) any applicable state statutes mandating health insurance
continuation coverage for employees. Section 4.11(i) of the PBC Disclosure
Schedule lists all of the former employees of PBC or any ERISA Affiliate and
their beneficiaries who have elected or are eligible to elect COBRA continuation
of health insurance coverage under any Plan offering health insurance or medical
benefits.

         (j) Neither PBC nor any ERISA Affiliate has incurred any liability to
the DOL, the Pension Benefit Guaranty Corporation (the "PBGC") or the IRS in
connection with any of the Employee Plans, and, to the best knowledge of PBC, no
condition exists that presents a risk to PBC or any ERISA Affiliate of incurring
any liability to the DOL, the PBGC or the IRS.

         (k) For the purpose of this Section 4.11, the term "ERISA Affiliate"
shall mean (i) any related company or trade or business that is required to be
aggregated with PBC under Code sections 414(b), (c), (m) or (o); (ii) any other
company, entity or trade or business that has adopted or has ever participated
in any Employee Plan; and (iii) any predecessor or successor company or trade or
business of PBC or any entity described in 4.11(k)(i) and (k)(ii).

         (l) For the purpose of this Section 4.11, the term "Employee" shall be
considered to include common law employees of PBC or any ERISA Affiliate,
individuals rendering personal services to PBC or any ERISA Affiliate as
independent contractors and leased employees of PBC or any ERISA Affiliate as
defined in Code section 414(n) and the regulations promulgated pursuant thereto.

         (m) No lien, security interests or other encumbrances exist with
respect to any of the assets of PBC or any ERISA Affiliate which were imposed
pursuant to the terms of the Code or ERISA and, to the knowledge of PBC, no
condition exists or could occur that would result in the imposition of such
liens, security interests or encumbrances arising from or relating to the
Employee Plans.

4.12 PBC Information. The information relating to PBC and its Subsidiaries which
is provided to BancorpSouth by PBC or its representatives for inclusion in the
Proxy Statement and the S-4, or in any other document filed with any other
regulatory agency in connection herewith, will not contain any untrue statement
of a material fact or omit to state a material fact necessary to make the
statements therein, in light of the circumstances in which they are made, not
misleading. The S-4 and the Proxy Statement (except for such portions thereof
that relate only to BancorpSouth or any of its Subsidiaries) will comply with
the provisions of the Securities Act of 1933, as amended (the "Securities Act"),
the Securities Exchange Act of 1934, as amended (the "Exchange Act") and the
rules and regulations thereunder.

4.13 Compliance with Applicable Law. PBC and each of its Subsidiaries hold, and
have at all times held, all licenses, franchises, permits and authorizations
necessary for the lawful conduct of their respective businesses under and
pursuant to all, and have complied in all material respects with and are not in
default in any material respect under any, applicable law, statute, order, rule,
regulation, policy and/or guideline of any Governmental Entity relating to PBC
or any of its Subsidiaries, and neither PBC nor any of its Subsidiaries has
received notice, and PBC does not know, of any violations of any of the above.

4.14 Certain Contracts.

         (a) Set forth in Section 4.14(a) of the PBC Disclosure Schedule is a
list of any contract or agreement (whether written or oral) to which PBC or any
of its Subsidiaries is a party to or bound by any contract or agreement (whether
written or oral) (i) with respect to the employment of any employees, officers,
directors or consultants, (ii) which, upon the consummation of the transactions
contemplated by this Agreement, will (either alone or upon the occurrence of any
additional acts or events) result in any payment or benefits (whether of
severance pay or otherwise) becoming due, or the acceleration or vesting


                                       18


of any rights to any payment or benefits, from BancorpSouth, PBC, the Surviving
Corporation or any of their respective Subsidiaries to any employee, officer,
director or consultant thereof, (iii) which is a material contract (as defined
in Item 601(b)(10) of Regulation S-K of the SEC) to be performed after the date

counterparties thereto. PBC and each of its Subsidiaries has performed all
obligations required to be performed by it to date under each PBC Contract
described in clause (iii) of Section 4.14(a). Except as set forth in Section
4.14(b) of the PBC Disclosure Schedule, no event or condition exists which
constitutes or, after notice or lapse of time or both, would constitute, a
default on the part of PBC or any of its Subsidiaries under any PBC Contract
described in clause (iii) of Section 4.14(a). No other party to any PBC Contract
described in clause (iii) of Section 4.14(a) is, to the knowledge of PBC, in
default in any respect thereunder.

Subsidiaries is subject to any cease-and-desist or other order issued by, or is
a party to any written agreement, consent agreement or memorandum of
understanding with, or is a party to any commitment letter or similar
undertaking to, or is subject to any order or directive by, or is a recipient of
any extraordinary supervisory letter from, or has adopted any board resolutions
at the request of (each, a "Regulatory Agreement") any Regulatory Agency or
other Governmental Entity that restricts the conduct of its business or that in
any manner relates to its capital adequacy, its credit policies, its management
or its business, nor has PBC or any of its Subsidiaries been advised by any
Regulatory Agency or other Governmental Entity that it is considering issuing or
requesting any Regulatory Agreement.

4.16 Business Combination Provision; Takeover Laws. PBC, its Subsidiaries, and
this Agreement and the transactions contemplated hereby, are not subject to or
are exempt from the requirements of any "moratorium", "control share," "fair

common law, regulations and ordinances, and with all applicable decrees, orders
and contractual obligations relating to pollution or the discharge of, or
exposure to, Hazardous Materials (as hereinafter defined) in the environment or
workplace ("Environmental Laws");

         (b) There is no suit, claim, action or proceeding, pending or, to the
knowledge of PBC, threatened, before any Governmental Entity or other forum in
which PBC, any of its Subsidiaries, or, to the knowledge of PBC, any
Participation Facility or any Loan Property, has been or, with respect to
threatened proceedings, may be, named as a defendant (i) for alleged
noncompliance (including by any predecessor) with any Environmental Laws, or
(ii) relating to the release, threatened release or exposure to any Hazardous
Material whether or not occurring at or on a site owned, leased or operated by
PBC or any of its Subsidiaries, any Participation Facility or any Loan Property;


                                       19

subject to bankruptcy, insolvency, fraudulent conveyance and other laws of
general applicability relating to or affecting creditors' rights and to general
equity principles.

4.21 Property. PBC has good and marketable title, free and clear of all liens,
encumbrances, mortgages, pledges, charges, defaults or equitable interests, to

any of its Subsidiaries as lessee leases real or personal property are valid and
enforceable in accordance with their respective terms, and neither PBC nor any
of its Subsidiaries is, nor to the knowledge of PBC, is any other party thereto,
in default thereunder.

4.22 Certain Transactions.

         (a) Neither PBC nor its Subsidiaries has provided, maintained,

Schedules, neither PBC nor its Subsidiaries are involved in any contract,

4.23 Business and Relationships.

         (a) No customer or group of customers of PBC or PBB has, since June 30,

approved by the Board of Directors of BancorpSouth. The Board of Directors of
BancorpSouth has directed officers of BancorpSouth to so approve this Agreement
and the transactions contemplated herein in its capacity as the sole shareholder
of the BancorpSouth Bank. Other than the approval of the Board of Directors of
BancorpSouth Bank, no other corporate proceedings on the part of BancorpSouth or
BancorpSouth's Subsidiaries are necessary to approve this Agreement and to
consummate the transactions contemplated hereby. This Agreement has been duly
and validly executed and delivered by BancorpSouth and constitutes a valid and
binding obligation of BancorpSouth, enforceable against BancorpSouth in
accordance with its terms, except as enforcement may be limited by general

remedies generally.

Governing Documents or the BancorpSouth Bank Governing Documents, or (ii) unless
such violation, conflict or breach would not have a Material Adverse Effect on
BancorpSouth and assuming that the consents and approvals referred to in Section
5.4 are duly obtained, (A) violate any statute, code, ordinance, rule,
regulation, judgment, order, writ, decree or injunction applicable to
BancorpSouth or any of its Subsidiaries or any of their respective properties or
assets, or (B) violate, conflict with, result in a breach of any provision of or
the loss of any benefit under, constitute a default (or an event which, with
notice or lapse of time, or both, would constitute a default) under, result in
the termination of or a right of termination or cancellation under, accelerate
the performance required by, or result in the creation of any lien, pledge,
security interest, charge or other encumbrance upon any of the respective
properties or assets of BancorpSouth or any of its Subsidiaries under, any of
the terms, conditions or provisions of any material contract, as such term is
defined in Regulation S-X of the SEC.

required to be made with respect thereto, that they were required to file since
December 31, 1998 with any Regulatory Agency, and have paid all fees and
assessments due and payable in connection therewith.

5.6 Reorganization. BancorpSouth has no reason to believe that the Merger will
fail to qualify as a reorganization under Section 368(a) of the Code.

5.7 Financial Statements; SEC Reports.

         (a) The consolidated financial statements of BancorpSouth and its
subsidiaries (the "BancorpSouth Financial Statements"), including consolidated

Subsidiaries to be contained in the Proxy Statement and the S-4, or in any other
document filed with any other regulatory agency in connection herewith, will not
contain any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in light of the circumstances in which
they are made, not misleading. The S-4 and the Proxy Statement (except for such
portions thereof that relate only to PBC or any of its Subsidiaries) will comply
with the provisions of the Securities Act, the Exchange Act and the rules and
regulations thereunder.

5.10 Approvals. BancorpSouth knows of no reason why all regulatory approvals
required for the consummation of the transactions contemplated hereby

should not be obtained.

         (a) BancorpSouth and PBC shall promptly prepare and file with the SEC
the Proxy Statement, and BancorpSouth shall promptly prepare and file with the
SEC the S-4, in which the Proxy Statement will be included as a prospectus. Each
of PBC and BancorpSouth shall use its reasonable best efforts to have the S-4
declared effective under the Securities Act as promptly as practicable after
such filing, and PBC shall thereafter mail the Proxy Statement to its
shareholders as promptly as practicable. BancorpSouth shall also use its
reasonable best efforts to obtain all necessary state securities law or "Blue
Sky" permits and approvals required to carry out the transactions contemplated
by this Agreement.

         (b) The parties hereto shall cooperate with each other and use their
reasonable best efforts to promptly prepare and file all necessary
documentation, to effect all applications, notices, petitions and filings, and
to obtain as promptly as practicable all permits, consents, approvals and
authorizations of all third parties and Governmental Entities which are
necessary or advisable to consummate the transactions contemplated by this
Agreement (including, without limitation, the Holding Company Merger and the
Bank Merger). PBC and BancorpSouth shall have the right to review in advance,
and to the extent practicable each will consult the other on, in each case
subject to applicable laws relating to the exchange of information, all the
information relating to PBC or BancorpSouth, as the case may be, and any of
their respective Subsidiaries, which appears in any filing made with, or written
materials submitted to, any third party or any Governmental Entity in connection
with the transactions contemplated by this Agreement. In exercising the
foregoing right, each of the parties hereto shall act reasonably and as promptly
as practicable. The parties hereto agree that they will consult with each other
with respect to the obtaining of all permits, consents, approvals and
authorizations of all third parties and Governmental Entities necessary or
advisable to consummate the transactions contemplated by this Agreement and each
party will keep the other apprised of the status of matters relating to
completion of the transactions contemplated herein.

         (c) BancorpSouth and PBC shall, upon request, furnish each other with
all information concerning themselves, their Subsidiaries, directors, officers
and shareholders and such other matters as may be reasonably necessary or
advisable in connection with the Proxy Statement, the S-4 or any other
statement, filing, notice or application made by or on behalf of BancorpSouth,
PBC or any of their



                                       28


respective Subsidiaries to any Governmental Entity in connection with the Merger
and the other transactions contemplated by this Agreement.

         (d) BancorpSouth and PBC shall promptly furnish each other with copies
of written communications received by BancorpSouth or PBC, as the case may be,
or any of their respective Subsidiaries, Affiliates or Associates (as such terms
are defined in Rule 12b-2 under the Exchange Act as in effect on the date of
this Agreement) from, or delivered by any of the foregoing to, any Governmental
Entity in respect of the transactions contemplated hereby.

7.2 Access to Information.

         (a) Upon reasonable notice and subject to applicable laws relating to
the exchange of information, PBC shall, and shall cause each of its Subsidiaries
to, afford to the officers, employees, accountants, attorneys, financial
advisors and other representatives (each, a "Representative") of BancorpSouth,
access during normal business hours during the period prior to the Effective
Time to all of its properties, books, contracts, commitments, records, officers,
employees, accountants, counsel and other representatives and, during such
period, it shall, and shall cause its Subsidiaries to, make available to
BancorpSouth all information concerning its business, properties and personnel
as BancorpSouth may reasonably request. In addition, PBC and each of its
Subsidiaries shall permit a Representative of BancorpSouth to have access to the
premises and observe the operations of PBC or any of its Subsidiaries, as the
case may be, to attend each meeting of their respective Boards of Directors and
committees thereof (other than during discussions regarding this Agreement and
the transactions contemplated hereby) and to meet with the officers of PBC and
its Subsidiaries responsible for the Financial Statements, the internal controls
of PBC and its Subsidiaries and the disclosure controls and procedures of PBC
and its Subsidiaries to discuss such matters as Buyer may deem reasonably
necessary or appropriate for BancorpSouth to satisfy its obligations under the
Sarbanes-Oxley Act of 2002 and any rules and regulations relating thereto.
Neither PBC nor any of its Subsidiaries shall be required to provide access to
or to disclose information where such access or disclosure would reasonably
violate the rights of its customers, reasonably jeopardize any attorney-client
privilege or contravene any law, rule, regulation, order, judgment, decree,
fiduciary duty or binding agreement entered into prior to the date of this
Agreement. PBC shall identify the nature of any such limitation on access and
disclosure, and the parties hereto will make appropriate substitute disclosure
arrangements under circumstances in which the restrictions of the preceding
sentence apply.

         (b) Notwithstanding anything in any other agreement to the contrary, no
investigation by BancorpSouth or its Representatives shall affect the
representations, warranties, covenants or agreements of PBC set forth herein,
and the parties shall remain responsible to the extent provided herein.

         (c) The parties agree that the provisions of the Confidentiality
Agreement, dated as of July 9, 2004, between PBC and BancorpSouth, shall survive
the execution (or termination) of this Agreement and remain in full force and
effect for the term thereof.

7.3 Shareholder Meeting. PBC shall take all steps in accordance with applicable
law necessary to duly call, give notice of, convene and hold a meeting of its
shareholders to be held as soon as is reasonably practicable after the date on
which the S-4 becomes effective for the purpose of voting upon the approval and
adoption of this Agreement. PBC will, through its Board of Directors, recommend
to its shareholders approval of this Agreement and the transactions contemplated
hereby and such other matters as may be submitted to its shareholders in
connection with this Agreement; provided, however, that PBC's Board of Directors
may submit this Agreement and the transactions contemplated herein to its
shareholders for approval without recommendation pursuant to Section 48-21-104
of the TBCA if PBC's Board of Directors determines in good faith that it must do
so in order to comply with its fiduciary duties.


                                       29


7.4 Legal Conditions to Merger. Each of BancorpSouth and PBC shall, and shall
cause its Subsidiaries to, use their reasonable best efforts (a) to take, or
cause to be taken, all actions necessary, proper or advisable to comply promptly
with all legal requirements which may be imposed on such party or its
Subsidiaries with respect to the Merger and, subject to the conditions set forth
in Article VIII hereof, to consummate the transactions contemplated by this
Agreement and (b) to obtain (and to cooperate with the other party to obtain)
any consent, authorization, order or approval of, or any exemption by, any
Governmental Entity and any other third party which is required to be obtained
by PBC or BancorpSouth or any of their respective Subsidiaries in connection
with the Merger and the other transactions contemplated by this Agreement, and
to comply with the terms and conditions of such consent, authorization, order or
approval.

7.5 Affiliates. PBC shall use its reasonable best efforts to cause each
director, executive officer and other person who is an "affiliate" (for purposes
of Rule 145 under the Securities Act) of such party to deliver to BancorpSouth,
as soon as practicable after the date of this Agreement, a written agreement, in
the form of Exhibit 7.5.

7.6 NYSE Listing. BancorpSouth shall make all filings required of it to cause
the shares of BancorpSouth Common Stock to be issued in the Merger to be
approved for listing on the NYSE, subject to official notice of issuance, as of
the Effective Time.

7.7 Employee Benefit Plans; Existing Agreements.

         (a) As of the Effective Time, the employees of PBC and its Subsidiaries
(the "PBC Employees") shall at the discretion of BancorpSouth either continue to
participate in the PBC Employee Plans or, to the extent permissible under the
terms of the BancorpSouth Plans, shall become eligible to participate in
BancorpSouth's employee benefit plans in which similarly situated employees of
BancorpSouth or BancorpSouth Bank participate, to the same extent as similarly
situated employees of BancorpSouth or BancorpSouth Bank (it being understood
that inclusion of PBC Employees in BancorpSouth's employee benefit plans may
occur at different times with respect to different plans) except as provided
below.

         (b) With respect to each BancorpSouth Plan that is an "employee benefit
plan," as defined in section 3(3) of ERISA, for purposes of determining
eligibility to participate, and entitlement to benefits, including for severance
benefits and vacation entitlement, service with PBC shall be treated as service
with BancorpSouth; provided, however, that such service shall not be recognized
to the extent that such recognition would result in a duplication or increase of
benefits; and provided further, that past service credit shall not be taken into
account for determining eligibility, vesting or accrual of benefits under the
BancorpSouth defined benefit pension plan. Such service also shall apply for
purposes of satisfying any waiting periods, evidence of insurability
requirements, or the application of any preexisting condition limitations. Each
BancorpSouth Plan shall waive pre-existing condition limitations to the same
extent waived under the applicable PBC Plan. PBC Employees shall be given credit
for amounts paid under a corresponding benefit plan during the same period for
purposes of applying deductibles, copayments and out-of-pocket maximums as
though such amounts had been paid in accordance with the terms and conditions of
the BancorpSouth Plan.

         (c) As of the Effective Time, except as described in Section 8.2(d)
below and except as otherwise agreed, BancorpSouth shall assume and honor and
shall cause the appropriate Subsidiaries of BancorpSouth to assume and to honor
in accordance with their terms all employment, severance and other compensation
agreements and arrangements existing prior to the execution of this Agreement
which are between PBC or any of its Subsidiaries and any director, officer or
employee thereof and which have been disclosed in the PBC Disclosure Schedule.


                                       30


         (d) BancorpSouth and PBC agree to cooperate and take all reasonable
actions to effect the merger of any employee benefit plan that is intended to be
qualified under section 401(a) of the Code into the appropriate tax-qualified
retirement plan of BancorpSouth after the Merger is completed, so that such plan
merger satisfies the requirements of section 414(l) of the Code; provided,
however, that BancorpSouth shall not be obligated to effect such a merger of a
plan unless such plan is fully funded under section 412 of the Code and section
302 of ERISA, to the extent applicable, and the merger would not jeopardize the
tax-qualified status of any BancorpSouth Plan.

         (e) Notwithstanding the preceding paragraph, if requested by
BancorpSouth, prior to the Effective Time, PBC shall freeze, amend or take other

such plans immediately prior to the Effective Time) that BancorpSouth, in its
sole discretion, deems advisable and not inconsistent with this Agreement, and

Agreement and their respective Subsidiaries shall take all such necessary action
as may be reasonably requested by BancorpSouth.

contemplated hereby and shall cooperate fully with the other party hereto to
that end.

7.11 Tax-Free Qualification. Each of BancorpSouth and PBC shall use its
reasonable best efforts not to, and shall use its reasonable best efforts not to

meaning of Section 368(a) of the Code.

indenture and other necessary documentation, getting necessary consents and

                                       31


         (a) In the event of any threatened or actual claim, action, suit,
proceeding or investigation, whether civil, criminal or administrative,
including, without limitation, any such claim, action, suit, proceeding or
investigation in which any person who is now, or has been at any time prior to
the date of this Agreement, or who becomes prior to the Effective Time, a
director or officer of PBC or any of its Subsidiaries (the "Indemnified
Parties") is, or is threatened to be, made a party based in whole or in part on,
or arising in whole or in part out of, or pertaining to (i) the fact that he or
she is or was a director or officer of PBC, any of the Subsidiaries of PBC or
any of their respective predecessors or affiliates or (ii) this Agreement or any
of the transactions contemplated hereby, whether in any case asserted or arising
before or after the Effective Time, the parties hereto agree to cooperate and
use their best efforts to defend against and respond thereto. It is understood
and agreed that, after the Effective Time, BancorpSouth shall indemnify and hold
harmless, subject in all respects to any limitations imposed by any statute,
rule, regulation, administrative interpretation, or other law, including any
procedural requirements or other conditions, each such Indemnified Party against
any losses, claims, damages, liabilities, costs, expenses (including reasonable
attorney's fees and expenses in advance of the final disposition of any claim,
suit, proceeding or investigation to each Indemnified Party), judgments, fines
and amounts paid in settlement in connection with any such threatened or actual
claim, action, suit, proceeding or investigation. In the event of any such
threatened or actual claim, action, suit, proceeding or investigation (whether
asserted or arising before or after the Effective Time), the Indemnified Parties
may retain counsel reasonably satisfactory to them after consultation with
BancorpSouth; provided, however, that (1) BancorpSouth shall have the right to
assume the defense thereof and, upon such assumption, BancorpSouth shall not be
liable to any Indemnified Party for any legal expenses of other counsel or any
other expenses subsequently incurred by any Indemnified Party in connection with
the defense thereof, except that if BancorpSouth elects not to assume such
defense or if counsel for the Indemnified Parties reasonably advises that there
are issues which raise conflicts of interest between BancorpSouth and the
Indemnified Parties, the Indemnified Parties may retain counsel reasonably
satisfactory to them after consultation with BancorpSouth, and BancorpSouth
shall pay the reasonable fees and expenses of such counsel for the Indemnified
Parties, (2) BancorpSouth shall in all cases be obligated pursuant to this
paragraph to pay for only one firm of counsel for all Indemnified Parties
(unless an ethical conflict of interest arises for such firm of counsel in
representing all Indemnified Parties), (3) BancorpSouth shall not be liable for
any settlement effected without its prior written consent (which consent shall
not be unreasonably withheld) and (4) BancorpSouth shall have no obligation
hereunder to any Indemnified Party if that indemnification of such Indemnified
Party in the manner contemplated hereby is prohibited by any statute, rule,
regulation, administrative interpretation, or other law. Any Indemnified Party
wishing to claim Indemnification under this Section 7.13, upon learning of any
such claim, action, suit, proceeding or investigation, shall promptly notify
BancorpSouth thereof; provided that the failure to so notify shall not affect
the obligations of BancorpSouth under this Section 7.13 except to he extent such
failure to notify materially prejudices BancorpSouth. BancorpSouth's obligations
under this Section 7.13 shall continue in full force and effect without time
limit from and after the Effective Time.

         (b) In the event BancorpSouth or any of its successors or assigns (i)
consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger,
or (ii) transfers or conveys all or substantially all of its properties and
assets to any person, then, and in each such case, to the extent necessary,
proper provision shall be made so that the successors and assigns of
BancorpSouth assume the obligations set forth in this Section.

         (c) The provisions of this Section 7.13 are intended to be for the
benefit of, and shall be enforceable by, each Indemnified Party and his or her
heirs and representatives.

Effective Time, whether before or after approval of the matters presented in
connection with the Merger by the shareholders of PBC:

         (a) By mutual consent of PBC and BancorpSouth in a written instrument,
if the Board of Directors of each so determines by a vote of a majority of the
members of its entire Board;

         (b) By either BancorpSouth or PBC upon written notice to the other
party (i) 60 days after the date on which any request or application for a
Requisite Regulatory Approval shall have been denied or withdrawn at the request
or recommendation of the Governmental Entity which must grant such Requisite
Regulatory Approval, unless within the 60-day period following such denial or
withdrawal a petition for rehearing or an amended application has been filed
with the applicable Governmental Entity; provided, however, that no party shall
have the right to terminate this Agreement pursuant to this Section 9.1(b)(i) if
such denial or request or recommendation for withdrawal shall be due to the
failure of the party seeking to terminate this Agreement to perform or observe
the covenants and agreements of such party set forth herein or (ii) if any
Governmental Entity of competent jurisdiction shall have issued a final
nonappealable order enjoining or otherwise prohibiting the Merger;

         (c) By BancorpSouth or PBC upon written notice to the other party if
the Merger shall not have been consummated on or before February 28, 2005,
unless the failure of the Closing to occur by such date shall be due to the
failure of the party seeking to terminate this Agreement to perform or observe
the covenants and agreements of such party set forth herein;

         (d) By BancorpSouth upon written notice to PBC if any approval of the
shareholders of PBC required for the consummation of the Merger shall not have
been obtained by reason of the failure to obtain the required vote at a
respective duly held meeting of such shareholders or at any adjournment or
postponement thereof;

         (e) By either BancorpSouth or PBC upon written notice to the other
party (provided that the terminating party is not then in breach of any
representation or warranty or material breach of any covenant or other agreement
contained herein) in the event of either: (i) if any of the representations or



                                       35



warranties set forth in this Agreement on the part of the other party hereto
shall be or become untrue or incorrect, and such representation is either
incapable, by its nature, of being cured or is not cured within 30 calendar days
following the giving of written notice thereof to the party making such
representation; or (ii) a material breach by the other party of any of the
covenants or agreements contained in this Agreement, and such breach is either
incapable, by its nature, of being cured or is not cured within 30 calendar days
following the giving of written notice thereof to such other party; or

         (f) By BancorpSouth upon written notice to PBC if PBC's Board of
Directors shall have failed to recommend in the Proxy Statement that PBC's
shareholders approve and adopt this Agreement, or PBC's Board of Directors shall
have withdrawn, modified or changed, in a manner adverse to BancorpSouth, its
approval or recommendation of this Agreement and the transactions contemplated
hereby, or if PBC enters into any letter of intent, agreement in principle, or
acquisition or similar agreement related or with respect to any Acquisition
Proposal.

9.2 Effect of Termination. In the event of termination of this Agreement by
either BancorpSouth or PBC as provided in Section 9.1, this Agreement shall
forthwith become void and have no effect except (i) Sections 9.2, 10.3, 10.4 and
10.12 shall survive any termination of this Agreement (ii) that notwithstanding
anything to the contrary contained in this Agreement, no party shall be relieved
or released from any liabilities or damages arising out of its breach of any
provision of this Agreement, and PBC shall not be relieved or released from any
obligation to make payment to BancorpSouth pursuant to Section 6.1(d) hereof.

9.3 Amendment. Subject to compliance with applicable law, this Agreement may be
amended by the parties hereto, by action taken or authorized by their respective
Boards of Directors, at any time before or after approval of the matters
presented in connection with the Merger by the shareholders of PBC; provided,
however, that after any approval of the transactions contemplated by this
Agreement by PBC's shareholders, there may not be, without further approval of
such shareholders, any amendment of this Agreement which reduces the amount or
changes the form of the consideration to be delivered to such shareholders
hereunder other than as contemplated by this Agreement. This Agreement may not
be amended except by an instrument in writing signed on behalf of each of the
parties hereto.

9.4 Extension; Waiver. At any time prior to the Effective Time, each of the
parties hereto, by action taken or authorized by its Board of Directors, may, to
the extent legally allowed, (a) extend the time for the performance of any of
the obligations or other acts of the other party hereto, (b) waive any
inaccuracies in the representations and warranties of the other party contained
herein or in any document delivered pursuant hereto and (c) waive compliance
with any of the agreements or conditions of the other party contained herein.
Any agreement on the part of a party hereto to any such extension or waiver
shall be valid only if set forth in a written instrument signed on behalf of
such party, but such extension or waiver or failure to insist on strict
compliance with an obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.

         (a) In this Agreement, unless a contrary intention appears, (i) the

to this Agreement as a whole and not to any particular Article, Section or other
subdivision, and (ii) when a reference is made in this Agreement to Articles,
Sections, Exhibits or Schedules, such reference shall be to an Article, Section
of or Exhibit or Schedule to this Agreement, as applicable. Whenever the words
"include", "includes" or "including" are used in this Agreement, they shall be
deemed to be followed by the words "without limitation." The phrases "the date
of this Agreement", "the date hereof" and terms of similar import, unless the
context


                                       37



otherwise requires, shall be deemed to refer to September 17, 2004. Unless the
context otherwise requires, when used in this Agreement, (i) the singular shall
include the plural, the plural shall include the singular, and all nouns,
pronouns and any variations thereof shall be deemed to refer to the masculine,
feminine or neuter, as the identity of the person or persons may require, and
(ii) the term "or" shall mean "and/or." For purposes of this Agreement,
"knowledge" means, with respect to an individual, such individual is actually
aware, after reasonable inquiry, of the particular fact, matter, circumstance or
other item, and, with respect to any party, entity or other person other than an
individual, any individual who is serving as a director, chairman, chief
executive officer, president, chief operating officer, chief financial officer,
chief accounting officer, controller, chief credit officer, general counsel,
senior or executive vice president, or regional chairman of such party, entity
or other person or other officer, regardless of title, thereof charged with or
responsible for the oversight of a particular area, department or function to
which the subject matter relates, has or at any time had "knowledge" of such
fact, matter, circumstance or other item. References to any document (including
this Agreement) are references to that document as amended, consolidated,
supplemented, novated or replaced by the parties from time to time. References
to any party to this Agreement shall include references to its respective
successors and permitted assigns. References to law are references to that law
as amended, consolidated, supplemented or replaced from time to time, and shall
include references to any constitutional provision, treaty, decree, convention,
statute, act, regulation, rule, ordinance, subordinate legislation, rule of
common law and of equity and judgment and shall include the requirements of any
applicable stock exchange. References to a judgment shall include references to
any order, injunction, decree, determination or award of any court or tribunal.
References to any Governmental Entity or Regulatory Agency include any successor
to that Governmental Entity or Regulatory Agency.

         (b) The table of contents and headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. The parties hereto have each negotiated the
terms hereof, reviewed this Agreement carefully, and discussed it with their
respective legal counsel. It is the intent of the parties that each word, phrase
and sentence and other part hereof shall be given its plain meaning. No
provision of this Agreement shall be interpreted or construed against any party
hereto solely because such party or its legal representative drafted such
provision.

10.6 Defined Terms. Certain terms used in this Agreement have the meanings
ascribed thereto herein, and shall be applicable to the singular and the plural
forms of such terms, except as otherwise provided herein.

10.7 Counterparts. This Agreement may be executed in counterparts, all of which
shall be considered one and the same instrument and shall become effective when
counterparts have been signed by each of the parties and delivered to the other
party hereto, it being understood that all parties need not sign the same
counterpart.

10.8 Entire Agreement. This Agreement (including the schedules, exhibits,

                           AFFILIATE LETTER AGREEMENT


                                 _________, 2004

BancorpSouth, Inc.
One Mississippi Plaza
Tupelo, Mississippi 38804

Ladies and Gentlemen:

         I have been advised that as of the date of this letter I may be deemed
to be an "affiliate" of Premier Bancorp, Inc., a Tennessee corporation ("PBI"),
as the term "affiliate" is defined for purposes of paragraphs (c) and (d) of
Rule 145 of the rules and regulations of the Securities and Exchange Commission
(the "SEC") under the Securities Act of 1933, as amended (the "Securities Act").
I understand that pursuant to the terms of the Agreement and Plan of Merger,
dated as of September ___, 2004 (the "Merger Agreement"), between BancorpSouth,
Inc., a Mississippi corporation ("BancorpSouth"), and PBI, PBI plans to merge
with and into BancorpSouth (the "Merger").

         I understand that as a result of the Merger, I may receive shares of
common stock, par value $2.50 per share, of BancorpSouth (the "BancorpSouth
Common Stock") in exchange for shares of common stock, par value $1.00 per
share, of PBI (the "PBI Common Stock").

         I represent and warrant that I have carefully read this letter and
reviewed the Merger Agreement and discussed the requirements of these documents
and other applicable limitations upon my ability to sell, transfer or otherwise
dispose of BancorpSouth Common Stock and PBI Common Stock, to the extent I felt
necessary, with my counsel or counsel for PBI.

         I hereby represent, warrant and covenant with and to BancorpSouth that
in the event that I receive any BancorpSouth Common Stock as a result of the
Merger:

         1. I shall not make any sale, transfer or other disposition of the
BancorpSouth Common Stock unless (i) such sale, transfer or other disposition
has been registered under the Securities Act, (ii) such sale, transfer or other
disposition is made in conformity with Rule 145 under the Securities Act (as
such rule may be amended from time to time), or (iii) in the opinion of counsel
in form and substance reasonably acceptable to BancorpSouth, or under a "no
action" letter obtained by me from the staff of the SEC, such sale, transfer or
other disposition will not violate or is otherwise exempt from registration
under the Securities Act.

         2. I understand that BancorpSouth is under no obligation to register
the sale, transfer or other disposition of BancorpSouth Common Stock by me or on
my behalf under the Securities Act or to take any other action necessary in
order to make compliance with an exemption from such registration available,
other than with respect to its obligation to file reports under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), in a timely manner. Upon
request, BancorpSouth agrees to provide to me a written statement that it has
complied with such reporting requirements.

         3. I understand that stop transfer instructions may be given to
BancorpSouth's transfer agent with respect to shares of BancorpSouth Common
Stock issued to me as a result of the Merger and that there will be placed on
the certificates representing these shares of BancorpSouth Common Stock issued
to me, or any substitutions therefor, a legend stating in substance:




"THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO
WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES
REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE
TERMS OF A LETTER AGREEMENT DATED ________, 2004 BETWEEN THE REGISTERED HOLDER
HEREOF TO BANCORPSOUTH, INC., A COPY OF WHICH AGREEMENT IS ON FILE AT THE
PRINCIPAL OFFICES OF BANCORPSOUTH, INC."

         4. I understand that, unless the transfer by me of my BancorpSouth
Common Stock has been registered under the Securities Act or such transfer is
made in conformity with the provisions of Rule 145(d) under the Securities Act,
BancorpSouth reserves the right, in its sole discretion, to place the following
legend on the certificates issued to my transferee:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES
IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933
APPLIES. THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR
RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE
SECURITIES ACT OF 1933 AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE
TRANSFERRED EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT OF 1933."

         It is understood and agreed that the legends set forth in paragraphs 3
and 4 above shall be removed by delivery of substitute certificates without such
legend at such time as the BancorpSouth Common Stock may be sold by me pursuant
to Rule 145(d)(3) under the Exchange Act, or if I shall have delivered to
BancorpSouth (i) a copy of a "no action" letter from the staff of the SEC or an
opinion of counsel, in form and substance reasonably satisfactory to
BancorpSouth, to the effect that such legend is not required for purposes of the
Securities Act, or (ii) evidence or representations and warranties satisfactory
to BancorpSouth that BancorpSouth Common Stock represented by such certificates
is being or has been sold in conformity with the provisions of Rule 145(d).

         I further understand and agree that this letter agreement shall apply
to all shares of BancorpSouth Common Stock received by me in connection with the
Merger, and I further represent, warrant and covenant with and to BancorpSouth
that I will have, and will cause each of the other parties whose shares are
deemed to be beneficially owned by me to have, all shares of PBI Common Stock or
BancorpSouth Common Stock owned by me or such parties registered in my name or
the name of such parties, as applicable, prior to the effective date of the
Merger and not the name of any bank, broker or dealer, nominee or clearing
house.











                                       2





         I further understand and agree that, in the event that at any time
after the date of this letter agreement I become and officer, director or
employee of BancorpSouth or any of its subsidiaries, I will be bound by the
insider trading policies of BancorpSouth applicable to such position, as adopted
and amended from time to time.

                                           Very truly yours,


                                           Signature:
