              REPRESENTATIONS WITH RESPECT TO UNREGISTERED STOCK
              --------------------------------------------------

         Buyer represents and undertake that:

         4.1   Buyer is acquiring the Stock for its own account and not with a
               view to their distribution within the meaning of Section 2(11) of
               the Securities Act of 1933, as amended, (the "1933 Act") and the
               rules and regulations thereunder. None of the Stock will be
               transferred by or through any shareholder of Buyer in violation
               of the 1933 Act or any state securities laws. Buyer will
               indemnify Seller against any loss, liability or expense
               (including reasonable attorneys' fees and out-of-pocket expenses)
               incurred by Seller by reason of any breach by Buyer or any
               shareholder of Buyer of this Section 4.1.

         4.2   Buyer understands and acknowledges that Stock has not been
               registered under either the 1933 Act or any state securities laws
               and is being offered pursuant to exemptions under such laws.
               Buyer further understands that the Stock cannot be resold or
               otherwise transferred unless such shares are registered under the
               1933 Act and any applicable state securities laws or unless
               exemptions from registration are available.

         4.3   Buyer understands and acknowledges that the sale, transfer,
               pledge, distribution or any other disposition of Stock will be
               restricted.

         4.4   Buyer understands that Buyer must bear the economic risk of
               investment in the Stock for an indefinite period of time because
               such shares have not been registered with the

                                       4
<PAGE>

               SEC under the 1933 Act or any state securities laws and,
               therefore, cannot be sold unless they are subsequently registered
               under the 1933 Act or any state securities laws or an exemption
               from registration is available.

                                   ARTICLE 5

               REPRESENTATIONS AND WARRANTIES OF SELLER AND PSA
               ------------------------------------------------

Seller and PSA, as applicable, represents and warrants as follows:

corporate power to own and sell its properties and to carry on its business as
it is now being conducted and is duly qualified to do business and is in good
standing in every jurisdiction where qualification is necessary for the
operation of its business. PSA is a corporation duly organized, validly existing
and in good standing under the laws of the state of Tennessee, has the corporate
power to own and sell its properties and to carry on its business as it is now
being conducted and is duly qualified to do business and is in good standing in
every jurisdiction where qualification is necessary for the operation of its
business. Seller certifies that the Articles of Incorporation and Bylaws of PSA
furnished to Buyer pursuant to Section 9.1 hereof are true and correct of the
Closing Date. The business of PSA is being and has been operated in all respects
in compliance with the Articles of Incorporation and Bylaws of PSA.

     5.2   Authority Relative to Agreement. Seller has all requisite corporate
           -------------------------------
power and authority to enter into this Agreement and to carry out its
obligations hereunder. This Agreement constitutes a legal, valid and binding
obligation of Seller enforceable against Seller according to its terms, except
as may be limited by applicable bankruptcy, insolvency or other similar laws
affecting

                                       5
<PAGE>

the rights of creditors generally or equitable principles relating to the
granting of extraordinary remedies.

     The execution, delivery and performance of this Agreement and the
consummation of the transactions contemplated hereby have been duly authorized
by the Board of Directors of Seller, and no other corporate proceedings on the
part of Seller are necessary to authorize this Agreement and the transactions
contemplated hereby. Neither the execution and delivery of this Agreement by
Seller, the consummation by Seller of the transactions contemplated hereby, nor
the compliance by Seller with the terms and provisions of this Agreement will
conflict with, violate or result in a breach of any of the terms, conditions or
provisions of the Articles of Incorporation, by-laws, resolutions or authorities
of Seller, or any statute, judgment, order, injunction, decree, regulation or
ruling of any court or governmental authority to which Seller is subject. The
consummation of the transactions contemplated by this Agreement will not result
in a breach of any agreement, contract, or commitment of Seller or constitute a
default thereunder, or, with respect to any agreement, contract or commitment,
give to others any rights or termination, cancellation or acceleration
thereunder, and no indenture, instrument, agreement, contract or commitment to
which Seller is a party will be violated or breached so as to prevent such
consummation.

     No authorization, consent or approval of, or filing with, any public body
or authority is or will be necessary for the execution, delivery or the
performance of this Agreement by Seller or the consummation by Seller of the
transactions contemplated by this Agreement, and the failure of the Seller to
obtain such authorization, consent or approval from any public body or
authority, if required, will not prevent the consummation by Seller of the
transactions contemplated by this Agreement.

<PAGE>

     5.3   Financial Statements. Seller has furnished Buyer with copies of PSA's

course of business since the respective dates thereof.

     5.4   Stock Title. Seller has good and marketable title to the Stock, free

contracts related to the issuance, sale or transfer of any stock or other
securities of PSA. None of the outstanding shares or other securities of PSA

municipal administrative order, constitution, law, ordinance, principle of
common law, regulation or state statute.

     5.5   Insurance. Insurance coverages shall be maintained by PSA through the
           ---------

as it is currently conducted. In connection with the deliveries required by this
Section, Seller shall provide, or cause PSA to provide, to Buyer (i) for each

     PSA is the absolute owner (or licensee, as applicable) of the Intellectual
Property, together with the goodwill of the business connected with the use of
and symbolized by same. None of the Intellectual Property is involved in any
pending or threatened lawsuits or administrative actions in the United Stated of
America or in any other country. Neither Seller nor PSA has received any notice
of invalidity or infringement of or conflict with the rights of others with
respect to such Intellectual Property. Seller and PSA have taken all necessary,
reasonable and prudent steps to protect the Intellectual Property from
infringement by any other firm, corporation, association or person. To the best
of Seller's and PSA's knowledge, no other firm, corporation, association or
person (a) has the right to use any such Intellectual Property in commerce
within the United States of America and in any of the other jurisdictions of
registration or use on the services on which they are now being used either in
identical form or in such near resemblance thereto as to be likely, when applied
to the services of any such firm, corporation, association or person, to cause
confusion with Seller's trademarks or to cause a mistake or to deceive, (b) is
claiming any ownership of or right to use such Intellectual Property, or (c) is
infringing upon any such Intellectual Property in any way. PSA is not, to the
best of PSA's knowledge, infringing any trademark, service mark, trade name or
copyright in the United States or any other country.

     5.7   Labor Relations. Seller and PSA have delivered to Buyer a list of all
           ---------------
persons receiving compensation from PSA (either directly or indirectly) in
connection with the business of PSA and a description of all compensation
arrangements affecting each of them. PSA has complied with all applicable laws,
rules and regulations relating to the employment of labor, including, but not
limited to, those relating to wages, hours, health and safety, unfair labor
practices, discrimination and payment of social security and all employment
related taxes. Neither Seller nor PSA has incurred any

                                       9
<PAGE>

liability for any arrears of wages or any tax penalty for failure to comply with
any of the foregoing. As of the date hereof there are no controversies pending
or threatened between PSA and any of its employees. There is no union campaign
or organizational activity being conducted to solicit cards from PSA's employees
to authorize a labor union to request a National Labor Relations Board
certification election with respect to any PSA employees. Neither the execution
of this Agreement nor the consummation of the transactions contemplated hereby
will cause Buyer, on or after the Closing Date, to assume, maintain or be
responsible for any of the foregoing or any relationship or contracts with any
group of PSA's employees or any labor organization.

     To the knowledge of PSA and Seller, no employee or director of PSA is a
party to is otherwise bound by any agreement or arrangement, including any
confidentiality, non-competition or proprietary rights agreement between such
employee or director and any other person ("Proprietary Rights Agreement") that
in any way adversely affect or will affect: (i) the performance of his or her
duties as an employee or director of PSA, or (ii) the ability of PSA to conduct
its business, including any Proprietary Rights Agreement with PSA by any such
employee or director. To PSA's knowledge, no director, officer or management
employee of PSA has given notice, whether written or oral, to PSA's personnel
office to terminate his or her employment with PSA.

     5.8   Employee Benefit Plans. Seller and PSA have delivered to Buyer copies
           ----------------------

employees or to which PSA contributes, has contributed or to which PSA is
obligated to contribute (by contract or otherwise) on behalf of its employees or
other persons, (b) deferred compensation, bonus, employee stock plan or other
such arrangements or commitments, that are maintained by or for PSA and its
employees or to which

                                       10
<PAGE>

Seller contributes, has contributed or to which PSA is obligated to contribute
(by contract or otherwise) on behalf of its employees or other persons, and (c)
any determination letters issued by the Internal Revenue Service or the Pension
Benefit Guaranty Corporation relating to (a) or (b) above.

     With regard to any employee benefit plans maintained by PSA, and with
regard to any employee benefit plan which is not maintained by PSA but to which
PSA contributes or is required to contribute (by contract or otherwise), the
execution and delivery of this Agreement by Seller and PSA and the consummation
of the transactions contemplated hereby do not constitute and will not result in
any "prohibited transaction" within the meaning of the ERISA or Article 4975 of
the Internal Revenue Code, as amended (the "Code"). PSA has not incurred any
liability to the Pension Benefit Guaranty Corporation. Neither any of the
benefit plans for employees currently maintained by PSA nor any trust or trusts
thereunder, and any of the foregoing not maintained by PSA but to which PSA
contributes or is required to contribute (by contract or otherwise), have been
terminated or have incurred any "accumulated funding deficiency," as such term
is defined in Article 302 of ERISA or Article 412 of the Code (whether or not
waived), nor have there been any unreported "reportable events," as such term is
defined in Article 4043 of ERISA, with respect thereto, since the effective date
of ERISA, nor do any such plans or trusts maintained by PSA or any such plans or
trusts not maintained by PSA but to which PSA contributes or is required to
contribute (by contract or otherwise) have any liability for unfunded vested
accrued benefits. Any PSA benefit plans or any trust or trusts related thereto
which have been terminated have been terminated in accordance with all
applicable laws and regulations and have not incurred any "accumulated funding
deficiency." Neither execution of this Agreement nor the consummation of the
transactions contemplated hereby will

                                       11
<PAGE>

cause Buyer to be responsible for any obligation or liability (with respect to
accrued benefits or otherwise) to any employee of PSA or to the Pension Benefit
Guaranty Corporation in respect of any such plans and agreements or any trust or
trusts thereunder, including any such plans, agreements or trusts which have
been terminated prior to the date hereof.

     5.9  Litigation. This Section briefly describes all actions, suits,
          ----------
proceedings, claims, complaints, and investigations pending or threatened
against PSA at law or in equity and before or by any federal, state, foreign or
other governmental body or any arbitration board in the United States of America
or anywhere else, or any claims or complaints made before or to any governmental
entity, to-wit:

     Complainants concerning payroll services provided by PSA to R.M.D.
     Corporation, a corporation with offices in Kentucky, and their affiliated
     restaurants (collectively, "RMD Corporation") have arisen from RMD
     Corporation. Controversy centers around payroll reporting for wage and hour
     employees.

     There are no judgments, orders, injunctions or decrees entered against PSA
which do or will limit, restrict or regulate its business in any respect. Except
as set forth in this Section 5.9, to PSA's and Seller's knowledge, there is no
material pending actions, suits, proceedings, claims, complaints or
investigations pending, nor have such been threatened and in no event has any
matter occurred or circumstances exist that may give rise to or serve as a basis
for the commencement of any such actions.

     Except as set forth in this Section 5.9, the relationship of PSA with its
customers is, to PSA's and Seller's knowledge, satisfactory and neither PSA nor
Seller has received any notice of any intention to terminate or adversely modify
any material term with respect to such relationship.

<PAGE>

     5.10 Compliance with Laws. The business of PSA is being and has been
          --------------------
operated in all respects in compliance with all applicable laws, rules,
regulations and policies. PSA has filed in a timely fashion all reports with
respect to its business which are required by law and has paid all amounts which
may be due with respect thereto or thereunder. PSA has not been notified by any
regulatory authority that it was or is in violation of any statute, ordinance,
regulation or order, which has application to its business, and, to the best of
PSA's knowledge, there is no violation of any such law, ordinance, regulation or
order which would result in any obligation, loss or expense to PSA or to Buyer
from and after the Closing Date. All governmental licenses and permits necessary
to the conduct of PSA's business are in force and effect and no unresolved
violations are or have been recorded with respect to any such license or permit,
and no proceeding is pending or threatened to revoke or limit any license or
permit. There are no inspection reports or similar communications issued or
released by any federal, state or local governmental agency in the United States
(and by any foreign governmental agency) relating to the business or properties
of PSA and which asserts a deficiency not yet corrected or a matter still in
dispute. Neither Seller nor PSA is aware of any proposed law, regulation, order
or guideline which would cause the business of PSA to be conducted in a
different manner than it is currently conducted by PSA.

     5.11 Delivery of Services. The services sold by PSA and its delivery
          --------------------
systems are in accordance with all applicable laws and regulations, including,
but not limited to, the laws and regulations of the laws of the jurisdictions in

indebtedness or obligation relating to any lending or borrowing or any other
liability or commitment, except current liabilities and commitments incurred in
the ordinary course of business; (b) pay any obligation or liability other than

the ordinary course of business since January 1, 2001; (c) enter into any

Exhibit "A"             NON-NEGOTIABLE PROMISSORY NOTE
                        ------------------------------

$1,400,000.00                                               Nashville, Tennessee
                                                                  March 30, 2001

         FOR VALUE RECEIVED, the undersigned PAYROLL COMPANY, INC., a Tennessee
corporation (hereinafter "Maker"), promises to pay to CONCORD EFS, INC., a
Delaware corporation (hereinafter "Payee"), the principal sum of ONE MILLION
FOUR HUNDRED THOUSAND and NO/100 DOLLARS ($1,400,000.00), together with interest
thereon from date hereof at rate of six percent (6%) per annum

         The outstanding principal balance hereunder, together with all accrued
but unpaid interest, shall be payable as follows:

         On March 30, 2002, the principal amount of $700,000.00, plus accrued
         but unpaid interest; and

         On March 30, 2003, the principal amount of $700,000.00, plus accrued
         but unpaid interest.

         Upon default in the payment of any installment of principal or interest
due under this Note, upon any default in the Maker's performance of or
compliance with the terms, conditions and provisions of that certain Sale and
Purchase Agreement of even date herewith between Maker and Payee, or upon any
default in the payment of any other indebtedness, liability or obligation now or
hereafter owed by the Maker to the Payee hereof, and upon Maker's failure to
cure same during the applicable time period set forth therein, if any, then, the
entire unpaid principal balance then owed upon this Note, together with all
interest then accrued, shall, at the option of the Payee at once become due and
payable.

         Both principal and interest shall be payable in lawful money of the
United States of America, which shall be legal tender in payment of all debts,
public and private, and due at the time of payment. Payments shall be made at
the office of Payee or at such other place as the holder hereof may designate in
writing.

         The principal and any unpaid installment of interest, as evidenced by
this Note, shall bear interest from the date of maturity (whether by demand,
acceleration or otherwise) until this Note is paid in full at the maximum rate
of interest Payee is permitted by law to contract for and charge.

         In the event any principal or interest due hereunder shall not be paid
when due, and such default shall continue for a period of ten (10) days from the
date such payment shall have been due and payable (without regard to any cure or
grace period), including principal and accrued interest becoming due by reason
of acceleration of the entire unpaid balance of the Note, Maker agrees to pay to
the Payee a late fee of six cents ($0.06) for each dollar so overdue.

<PAGE>


         If this Note is placed in the hands of an attorney for collection by
suit, or if collection by suit through the probate court, bankruptcy court, or
by any other legal proceedings for its payment or to enforce its collection,
Maker will pay all costs of collection and litigation incurred, together with
reasonable attorney's fees.

         The principal of this Note may be prepaid in part or full without
premium or penalty. All accrued and unpaid interest on the amount of the
principal being prepaid shall be payable on the date of any such principal
payment.

         The Maker and any endorsers hereof waive protest, demand, presentment,
and notice of dishonor, and agree that this Note may be extended, in whole or in
part, without limit as to the number of such extensions, or the period or
periods thereof, and without notice to it and without affecting its liability
thereon.

         This Note shall be construed and enforced in accordance with laws of
the State of Tennessee.

         This Note is non-negotiable by the Payee; provided, however, Payee
shall be permitted to transfer, endorse and assign this Note to any affiliate or
parent of Payee.

Exhibit "B"                       GUARANTY OF PAYMENT
                                  -------------------

         FOR VALUE RECEIVED and in consideration of advances made or to be made,
or credit given or to be given, or other financial accommodations from time to
time afforded or to be afforded to PAYROLL COMPANY, INC., a Tennessee
corporation (hereinafter called "Debtor"), by CONCORD EFS, INC., a Delaware
corporation, or its successors and assigns (all of which are hereinafter
collectively called "Creditor"), the undersigned hereby, jointly and severally,
guarantee the full and prompt payment to Creditor at maturity and at all times
thereafter of that certain Non-Negotiable Promissory Note dated on or about
March 30, 2001, in the original principal amount of $1,400,000.00, together with
interest, late fees and costs provided therein; and the undersigned further
agree(s) to pay all expenses, legal and/or otherwise (including court costs and
attorney's fees) paid or incurred by Creditor in endeavoring to collect such
indebtedness, obligations and liabilities, or any part thereof, and in enforcing
this guaranty. When the aforementioned obligations are paid in full, this
Guaranty of Payment shall expire and the holder and owner hereof shall deliver
the original hereof to the undersigned.

         In case of the dissolution, liquidation or insolvency (howsoever
evidenced) of, or the institution of bankruptcy or receivership proceedings
against said Debtor, all of said indebtedness, obligations and liabilities then
existing shall, at the option of Creditor, immediately become due or accrued and
payable from the undersigned.

         All dividends or other payments received from the Debtor, or on account
of the debt from whatsoever source, shall be taken and applied as payment in
gross, and this guaranty shall apply at the option of Creditor to and secure any
ultimate balance that shall remain owing to Creditor.

         Any payments made by the undersigned on the indebtedness of the Debtor
and resulting in the undersigned having a claim against the Debtor, shall be
subordinate to any and all then existing indebtedness owed Creditor by the
Debtor and also to such subsequent loans or advances which, at the option of
Creditor, may be made.

         This guaranty shall be a continuing absolute and unconditional
guaranty, subject to the limitation hereinabove set forth, and shall remain in
full force and effect until written notice of its discontinuance shall be
actually received by Creditor, and also until any and all said indebtedness,
obligations and liabilities existing before receipt of such notice shall be
fully paid.

         The liability hereunder shall in no wise be affected or impaired by
(and Creditor is hereby expressly authorized to make from time to time, without
notice to anyone), any sale, pledge, surrender, compromise, settlement, release,
renewal, extension, indulgence, alteration, substitution, exchange, change in,
modification or other disposition of any of said indebtedness, obligations and
liabilities, either express or implied, or of any contract or contracts
evidencing any thereof, or of any security or collateral therefor. The liability
hereunder shall in no wise be affected or impaired by any acceptance by Creditor
of any security for or other guarantors upon any of said indebtedness,
obligations or liabilities, or by any failure, neglect or omission on the

                                       3

<PAGE>

part of Creditor to realize upon or protect any of said indebtedness,
obligations or liabilities, or any collateral or security therefor, or to
exercise any lien upon or right of appropriation of any moneys, credits or
property of said Debtor, possessed by Creditor, toward the liquidation of said
indebtedness, obligations or liabilities, or by any application of payments or
credits thereon. Creditor shall have the exclusive right to determine how, when
and what application of payments and credits, if any, shall be made on said
indebtedness, obligations and liabilities, or any part of them. In order to hold
the undersigned liable hereunder, there shall be no obligation on the part of
Creditor at any time to first resort to, make demand on, file claim against, or
exhaust its remedies against the Debtor, or other persons or corporations, their
properties or estates, or to resort to and exhaust its remedies against any
collateral, security, property, liens or other rights whatsoever. It is
expressly agreed that the Creditor may at any time make demand for payment or
payments on, or bring suit against, the undersigned guarantors, jointly or
severally, or any one or more of the undersigned, less than all, without
impairing the rights of the Creditor against the others of the undersigned; and
that the Creditor may compound with any one or more of the undersigned for such
sums as it may see fit and release such of the undersigned from all further
liability to the Creditor for such indebtedness without impairing the right of
the Creditor to demand and collect the balance of such indebtedness from others
of the undersigned not so released.

         All diligence in collection or protection, and all presentment, demand,
protest and/or notice, as to any and everyone, of dishonor and of default and of
nonpayment and of the creation and existence of any and all of said
indebtedness, obligations and liabilities, and of any security and collateral
therefor, and of the acceptance of this guaranty, and of any and all extensions
of credit and indulgence hereunder, are hereby expressly waived.

         The granting of credit from time to time by Creditor to said Debtor in
excess of the amount to which the right of recovery under this guaranty is
limited and without notice to the undersigned, is hereby also authorized and
shall in no way affect or impair this guaranty.

         All paper discounted for said Debtor and all loans made to said Debtor,
when paid, shall be deemed to have been paid by said Debtor, unless express
notice in writing is given to said Creditor at the time by the undersigned that
it has been paid by them.

         No act of commission or omission of any kind, or at any time, upon the
part of said Creditor in respect to any matter whatsoever, shall in any way
affect or impair this guaranty.

         Creditor may, without any notice whatsoever to anyone, sell, assign, or
transfer all of said indebtedness, obligations and liabilities or any part
thereof, and in that event each and every immediate and successive assignee,
transferee, or holder of all or any part of said indebtedness, obligations and
liabilities, shall have the right to enforce this guaranty, for the benefit of
such assignee, transferee or holder, as fully as if such assignee, transferee or
holder were herein by name specifically given such rights, powers and benefits;
but Creditor shall have an unimpaired right, prior and superior to that of any
said assignee, transferee or holder, to enforce this guaranty

                                       4

for the benefit of Creditor, as to so much of said indebtedness, obligations and
liabilities that it has not sold, assigned or transferred.

         Notice to the undersigned guarantors of the acceptance of this guaranty
and of the making or renewing of any loan or paper is hereby expressed waived by
the undersigned. All rights, defenses and benefits conferred by any statute of
limitations to the undersigned affecting the enforcement hereof are expressly
waived and it is expressly agreed that any action may be maintained to enforce
this guaranty at any time.

         No release of any one or more of the guarantors of the indebtedness,
obligations and liabilities guaranteed hereby shall release any of the other
guarantors of said indebtedness, obligations and liabilities, unless and until
all of said indebtedness, obligations, and liabilities shall have been fully
paid and discharged.

         This guaranty shall be construed according to the law of the State of
Tennessee, in which State it shall be performed by the undersigned. This
guaranty and every part thereof, shall be binding upon the undersigned, jointly
and severally, and upon the heirs, legal representatives, successors and assigns
of all the undersigned, and each of them, respectively.

         After having carefully read this instrument the same was signed, sealed
and delivered by the undersigned, this 30th day of March, 2001, and was
thereafter received by Creditor in Nashville, Tennessee.
