                        EMPLOYEE STOCK PURCHASE AGREEMENT

         This Agreement is made as of the 1st day of June, 1999, by and between
UniPhy Healthcare, Inc., a Tennessee corporation (the "Corporation"), and R.
Dale Kennedy (the "Purchaser").

1.  PURCHASES OF SHARES

         1.1 Purchase. The Purchaser has agreed to purchase, and the Corporation
has agreed to sell to the Purchaser, 15,000 shares of the Corporation's Common
Stock (the "Purchased Shares") at a purchase price per share equal to the price
per share paid within 90 days from the date hereof by purchasers in the next
round of equity financing of the Corporation; provided, however, if the purchase
price has not been determined by an equity investment within such 90 day period,
the Corporation shall determine the purchase price per share (the "Purchase
Price"). The Corporation shall notify the Purchaser of the Purchase Price when
it is determined and the Purchaser shall have 10 days after receipt of notice of
the Purchase Price to either purchase the Purchased Shares or advise the
Corporation that he does not desire to purchase the Purchased Shares. The
Purchaser has no obligation to purchase the Purchased Shares when notified of
the Purchase Price and the Corporation has no obligation to sell the Purchased
Shares if the Purchase Price is not determined within 90 days of the date
hereof. If Purchaser elects to purchase the Purchased Shares, then within 10
days after receipt of notice of the Purchase Price the following documents, in
the forms used by the Corporation for sales of the common stock to employees,
shall be executed by the Purchaser:

                  1.  Promissory Note.

                  2.  Pledge Agreement.

                  3.  83(b) Election

                  4.  Investors' Rights Agreement.

                  5.  Voting Agreement.

                  6.  Rights of First Refusal and Co-Sale Agreement.

                  7.  Employee Proprietary Information and Invention Agreement.

         1.2 Legend. The certificates representing the Purchased Shares
purchased hereunder shall be marked with appropriate legends indicating that
such shares are subject to this Agreement and are restricted as provided herein.

         1.3 Other Agreements. The Purchaser and the Corporation acknowledge
that they shall be parties to an Investors' Rights Agreement, a Right of First

<PAGE>

Refusal and Co-Sale Agreement and a Voting Agreement, all as amended, executed
simultaneously herewith (collectively the "Related Agreements"), and the shares
covered hereby shall also be held pursuant to the applicable terms of the
Related Agreements.

2.  SECURITIES LAW COMPLIANCE

         2.1 Exemption from Registration. The Purchased Shares have not been
registered under the Securities Act of 1933, as amended (the "1933 Act"), and
are being issued to Purchaser in reliance upon the exemption from such
registration provided by Rule 701 of the Securities and Exchange Commission (the
"Commission") for stock issuances under compensatory benefit arrangements such
as this Agreement. Purchaser hereby acknowledges receipt of a copy of this
Agreement.

         2.2 Restricted Securities. Purchaser hereby confirms that Purchaser has
been informed that the Purchased Shares are "restricted securities" under the
1933 Act and may not be resold or transferred unless the Purchased Shares are
first registered under the federal securities laws or unless an exemption from
such registration is available. Accordingly, Purchaser hereby acknowledges that
Purchaser is prepared to hold the Purchased Shares for an indefinite period and
that Purchaser is aware that Rule 144 of the Commission issued under the 1933
Act is not presently available to exempt the offer and sale by the Purchaser of
the Purchased Shares from the registration requirements of the 1933 Act.
Purchaser is aware of the adoption of Rule 144 by the Commission, promulgated
under the Securities Act, which permits limited public resales of securities
acquired in a nonpublic offering, subject to the satisfaction of certain
conditions. Purchaser understands that under Rule 144, the conditions currently
include, among other things: the availability of certain current public
information about the issuer, the resale occurring not fewer than two years
after the party has purchased and paid for the securities to be sold, the sale
being through a broker in an unsolicited "broker's transaction" and the amount
of securities being sold during any three-month period not exceeding specified
limitations. Purchaser acknowledges and understands that the Company may not
satisfy the current public information requirement of Rule 144 at the time
Purchaser wishes to sell the Purchased Shares or other conditions under Rule 144
which are required of the Company and Purchaser understands that Purchaser will
thereby be precluded from selling the securities under Rule 144 even if the
two-year holding period of said Rule has been satisfied. Prior to Purchaser's
acquisition of the Purchased Shares, Purchaser represents and warrants that he
acquired sufficient information about the Company to reach an informed
knowledgeable decision to acquire the Purchased Shares. Purchaser has such
knowledge and experience in financial and business matters as to make Purchaser
capable of utilizing said information to evaluate the risks of the prospective
investment and to make an informed investment decision. Purchaser is

                                       2
<PAGE>

able to bear the economic risk of the entire loss of the Purchaser's investment
in the Purchased Stock.

3.  SPECIAL PROVISIONS

         3.1 Stockholder Rights. Until such time as the Corporation actually
exercises its repurchase rights under this Agreement, Purchaser (or any
successor in interest) shall have all the rights of a stockholder (including
voting and dividend rights) with respect to the Purchased Shares subject,
however, to any applicable transfer restrictions.

         3.2 Section 83(b) Election. Purchaser understands that under Section 83
of the Internal Revenue Code of 1986, as amended (the "Code"), the difference
between the Purchase Price paid for the Purchased Shares and their fair market
value on the date any forfeiture restrictions applicable to such shares lapse
will be reportable as ordinary income at the time. For this purpose, the term
"forfeiture restrictions" includes the right of the corporation to repurchase
the Purchased Shares pursuant to its Repurchase Right under Article 4 of this
Agreement. Purchaser understands that Purchaser may elect to be taxed at the
time the Purchased Shares are acquired to the extent, if any, the fair market
value of the Purchased Shares differs from the Purchase Price rather than when
and as such Purchased Shares cease to be subject to such forfeiture
restrictions, by filing an election under Section 83(b) of the code with the
I.R.S. within thirty (30) days after the date of purchase hereunder. If the fair
market value of the Purchased Shares at the date of purchase equals the Purchase
Price paid (and thus no tax is payable), the election must be made to avoid
adverse tax consequences in the future. The form for making this election is
available from the Company upon request. Purchaser understands that failure to
make this filing within the thirty (30) day period will result in the
recognition of ordinary income by the Purchaser (in the event the fair market
value of the Purchased Shares increases after the date of purchase) as the
forfeiture restrictions lapse. PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER'S
SOLE RESPONSIBILITY, AND NOT THE CORPORATION'S, TO FILE A TIMELY ELECTION UNDER
SECTION 83(b), EVEN IF PURCHASER REQUESTS THE CORPORATION OR ITS REPRESENTATIVES
TO MAKE THIS FILING ON PURCHASER'S BEHALF. PURCHASER IS RELYING SOLELY ON
PURCHASER'S ADVISORS WITH RESPECT TO THE DECISION AS TO WHETHER OR NOT TO FILE
AN 83(b) ELECTION.

4.  REPURCHASE RIGHT

         4.1 Grant. The Corporation is hereby granted the right (the "Repurchase
Right"), exercisable at any time during the sixty (60) day period following the
date the Purchaser ceases for any reason to be an employee of the Corporation or
a subsidiary (or such longer period of time mutually agreed to by the parties)
to repurchase at the Purchase Price all or at the discretion of the Corporation
any

                                       3
<PAGE>

portion of the Purchased Shares in which the Purchaser has not acquired a vested
interest in accordance with the vesting provisions of Section 4.3 (such shares
to be hereinafter called the "Unvested Shares").

         4.2 Exercise of the Repurchase Right. The Repurchase Right shall be
exercisable by written notice delivered to the Purchaser prior to the expiration
of the applicable sixty (60) day period specified in Section 4.1. The notice
shall indicate the number of Unvested Shares to be repurchased and the date on
which the repurchase is to be effected, such date to be not more than thirty
(30) days after the date of notice. To the extent one or more certificates
representing Unvested Shares may be held by the Purchaser, then Purchaser shall,
prior to the close of business on the date specified for the repurchase, deliver
to the Secretary of the Corporation the certificates representing the Unvested
Shares to be repurchased, each certificate to be properly endorsed for transfer.
The Corporation shall, concurrently with the receipt of such stock certificates,
pay to Purchaser in cash or cash equivalents (including the cancellation of any
purchase-money indebtedness), an amount equal to the original Purchase Price for
the Unvested Shares that are to be repurchased.

         4.3 Termination of the Repurchase Right.

                  (a) The Repurchase Right shall terminate with respect to any
Unvested Shares for which it is not timely exercised under Section 4.2. In
addition, the Repurchase Right shall terminate, and cease to be exercisable,
with respect to any and all Purchased Shares in which the Purchaser vests in
accordance with the schedule below. Accordingly, provided the Purchaser
continues to be an employee of the Corporation or a subsidiary, the Purchaser
shall acquire a vested interest in, and the Repurchase Right shall lapse with
respect to, the Purchased Shares in accordance with the following provisions:

                        (i) The Purchaser shall not acquire any vested interest
in, nor shall the Repurchase Right lapse with respect to, any Purchased Shares
during the initial twelve month period measured from May 1, 1999 (the "Vesting
Measurement Date").

                        (ii) From and after the expiration of the initial
one-year period measured from the Vesting Measurement Date, the Purchaser shall
acquire a vested interest in, and the Repurchase Right shall lapse with respect
to, the Purchased Shares in a series of four equal successive annual
installments of the number of shares equal to twenty-five percent (25%) of the
Purchased Shares on the first, second, third and fourth anniversaries of the
Vesting Measurement Date.

                  (b) All Purchased Shares as to which the Repurchase Right
lapses shall, however, continue to be subject to any rights of the Corporation
or any other party under the Related Agreements or other agreements between the
Corporation

                                       4
<PAGE>

and the Purchaser and may continue to be subject to the resale restrictions
under Rule 144 of the 1933 Act.

         4.4 Fractional Purchased Shares. No fractional shares shall be
repurchased by the Corporation. Accordingly, should the Repurchase Right extend
to a fractional share (in accordance with the vesting computation provisions of
Section 4.3), then such fractional share shall be added to any fractional share
in which the Purchaser is at such time vested in order to make one whole vested
share no longer subject to the Repurchase Right.

         4.5 Additional Purchased Shares or Substituted Securities. In the event
of any stock dividend, stock split, recapitalization or other change affecting
the Corporation's outstanding Common Stock as a class effected without receipt
of consideration, then any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which is
by reason of any such transaction distributed with respect to the Purchased
Shares shall be immediately subject to the Repurchase Right, but only to the
extent the Purchased Shares are at the time covered by such right. Appropriate
adjustments to reflect the distribution of such securities or property shall be
made to the number of Purchased Shares hereunder and to the price per share to
be paid upon the exercise of the Repurchase Right in order to reflect the effect
of any such transaction upon the Corporation's capital structure; provided,
however, that the aggregate Purchase Price for the shares subject to the
Repurchase Right shall remain the same.

         4.6 Corporate Transaction. In the event of any of the following
transactions (a "Corporate Transaction"): the sale, transfer or other
disposition of all or substantially all of the assets of the Corporation, or any
merger or consolidation of the Corporation with or into any other corporation or
corporations in which the holders of shares of the Corporation's outstanding
capital stock prior to such merger or consolidation own less than fifty percent
(50%) of the outstanding capital stock of the surviving corporation following
such merger or consolidation, then the Repurchase Right shall automatically
lapse in its entirety, and the Purchaser shall acquire a vested interest in all
the Purchased Shares upon the consummation of such Corporate Transaction.

         4.7 Transfer Restrictions on Unvested Shares. The Purchaser shall not
transfer by sale, assignment, hypothecation, donation or otherwise any of the
Stock or any interest therein subject to the Repurchase Right without the prior
express written consent of the Corporation. The Corporation shall not be
required (i) to transfer on its books any Purchased Shares which shall have been
transferred in violation of any of the provisions set forth in this Agreement or
(ii) to treat as owner of such shares or to accord the right to vote as such
owner or to pay dividends to any transferee to whom such shares shall have been
so transferred.

provisions shall be applicable in determining the parent and subsidiary
corporations of the Corporation:

                  (a) Any corporation (other than the Corporation) in an
unbroken chain of corporations ending with the Corporation shall be considered
to be a parent corporation of the Corporation, provided each such corporation in
the unbroken chain (other than the Corporation) owns, at the time of the
determination, stock possessing fifty percent (50%) or more of the total
combined voting power of all classes of stock in one of the other corporations
in such chain.

                  (b) Each corporation (other than the Corporation) in an
unbroken chain of corporations beginning with the Corporation shall be
considered to be a subsidiary of the Corporation, provided each such corporation
(other than the last corporation) in the unbroken chain owns, at the time of the
determination, stock possessing fifty percent (50%) or more of the total
combined voting power of all classes of stock in one of the other corporations
in such chain.

         5.3 No Employment or Service Contract. Nothing in this Agreement shall
confer upon the Purchaser any right to continue in the service of the
Corporation (or any parent or subsidiary corporation of the Corporation
employing or retaining Purchaser) for any period of time or interfere with or
restrict in any way the rights of the Corporation (or any parent or subsidiary
corporation of the Corporation employing or retaining Purchaser) or the
Purchaser, which rights are hereby expressly reserved by each, to terminate the
employment status of Purchaser at any time for any reason whatsoever, with or
without cause.

         5.4 Notices. Any notice required in connection with (i) the Repurchase

party may designate by ten (10) days' advance written notice under this Section
5.4 to all other parties to this Agreement.

         5.5 No Waiver. The failure of the Corporation (or its assignees) in any
instance to exercise the Repurchase Rights granted under Article 4 shall not
constitute a waiver of any other repurchase rights that may subsequently arise
under the provisions of this Agreement or any other agreement between the
Corporation and the Purchaser. No waiver of any breach or condition of this

                                       6

Agreement shall be deemed to be a waiver of any other or subsequent breach or
condition, whether of like or different nature.

         5.6 Cancellation of Shares. If the Corporation (or its assignees) shall
make available, at the time and place and in the amount and form provided in
this Agreement, the consideration for the Purchased Shares to be repurchased in
accordance with the provisions of this Agreement, then from and after such time,
the person from whom such shares are to be repurchased shall no longer have any
rights as a holder of such shares (other than the right to receive payment of
such consideration in accordance with this Agreement), and such shares shall be
deemed purchased in accordance with the applicable provisions hereof and the
Corporation (or its assignees) shall be deemed the owner and holder of such
shares, whether or not the certificates therefor have been delivered as required
by this Agreement.

         requested principal amount of the Loan are not generally available to
         first-class banks in the London Interbank Market;

                           (ii)     That the rate at which such dollar deposits
         are being offered will not adequately and fairly reflect the cost to
         Bank of making or maintaining the Loan during such Interest Period; or

                                      12
<PAGE>

                           (iii)    That reasonable means do not exist for
         ascertaining the LIBO Rate generally,

Bank shall, as soon as practicable thereafter, give written or telephonic
notice of such determination to the Borrower. In the event of any such
determination, the Loan shall thereafter bear interest at a rate based upon
such other comparable reference rate as reasonably determined by Bank.

         2.5      Change in Circumstances.

                  (a)      Notwithstanding any other provision herein, if after
the date of this Agreement any change in applicable Laws or regulations or in
the interpretation or administration thereof by any governmental authority
charged with the interpretation or administration thereof (whether or not
having the force of law) shall change the basis of taxation (but not the rates)
of payments to a Bank under any Loan made by Bank or any other fees or amounts
payable hereunder (other than taxes imposed on the overall net income or net
profits of Bank by the country in which Bank is located, or by the jurisdiction
in which Bank has its principal office, or by any political subdivision or
taxing authority therein), or shall impose, modify, or deem applicable any
reserve requirement, special deposit, insurance charge (including FDIC
insurance on Eurodollar deposits) or similar requirements against assets of,
deposits with or for the account of, or credit extended by, Bank or shall
impose on Bank or the London Interbank Market any other condition affecting
this Agreement or Loan made by Bank, and the result of any of the foregoing
shall be to increase the cost to Bank of making or maintaining its Loan or to
reduce the amount of any sum received or receivable by Bank for any of its Loan
hereunder (whether of principal, interest or otherwise) by an amount reasonably
deemed by Bank to be material, then the Borrowers will pay to Bank such
additional amount or amounts as will reasonably compensate Bank for such
additional costs.

                  b.       If either:

                           (i)      The introduction of, or any change in, or
         in the interpretation of, any United States or foreign law, rule or
         regulation; or

                           (ii)     Compliance with any directive, guidelines
         or request from any central bank or other United States or foreign
         governmental authority (whether or not having the force of law)
         promulgated or made after the date hereof (but excluding, however, any
         law, rule, regulation, interpretation, directive, guideline or request
         contemplated by or resulting from the report dated July, 1988,
         entitled "International Convergence of Capital Measurement and Capital
         Standards" issued by the Basic Committee on Banking Regulations and
         Supervisory Practices), affects or would affect the amount of capital
         required or expected to be maintained by Bank (or any lending office
         of Bank) or any corporation directly or indirectly owning or
         controlling Bank (or any lending office of Bank) based upon the
         existence of this Agreement, and Bank shall have determined that such
         introduction, change or compliance has or would have the effect of
         reducing the rate of return on Bank's capital or on the capital of
         such owning or controlling corporation as a consequence of its
         obligations hereunder to a level below that which Bank or such owning
         or controlling corporation could have achieved but for such
         introduction, change or

                                      13
<PAGE>

         compliance (after taking into account Bank's policies or the policies
         of such owning or controlling corporation, as the case may be,
         regarding capital adequacy) by an amount deemed by Bank (in its sole
         discretion) to be material, then the Borrower will pay to Bank such
         additional amount or amounts as will compensate Bank for such
         reduction attributable to making, funding and maintaining the Loan.

                  c.       A certificate of Bank setting forth such amount or
amounts as shall be necessary to compensate Bank (or its participating banks or
other entities pursuant to this Agreement), as specified in Paragraph (a) or
(b) above, as the case may be, shall be delivered to Borrower and shall be
conclusive absent manifest error; provided, however, that the Borrower shall be
responsible for compliance herewith and the payment of increased costs only to
the extent:

                           (i)      Any change in applicable Laws giving rise
         to increased costs occurs after the date of this Agreement; and

                           (ii)     Such change in Laws or the application
         thereof applies generally to the banking industry and is not the
         result of the Bank having inadequate or substandard capital as
         determined by its regulators; and

                           (iii)    The affected Bank gives notice of the
         change giving rise to increased costs within one hundred eighty (180)
         Business Days after the date on which Bank has, or with reasonable
         diligence should have had, knowledge of the change, or else Bank can
         only collect costs from and after the date of the notice.

Subject to the foregoing, the Borrower shall pay the affected Bank the amount
shown as due on any such certificate within ten (10) days after its receipt of
such certificate.

                  d.       The protection of this Section 2.5 shall be
available to Bank regardless of any possible contention of invalidity or
inapplicability of the law, regulation or condition that shall have been
imposed.

         2.6      Change in Legality. Notwithstanding anything to the contrary
herein contained, if any change in any law or regulation or in interpretation
thereof by any governmental authority charged with the administration or
interpretation thereof shall make it unlawful for Bank to make or maintain a
Eurodollar Loan, then, by written notice to the Borrower, the Loan shall
thereafter bear interest at a rate based upon such other comparable reference
rate as reasonably determined by Bank.

         2.7      Optional Prepayment - Premiums in Certain Events.

                  (a)      The Borrower may, upon three (3) Business Day's
prior written notice to the Bank, and upon payment of all premiums set forth in
Subparagraph (c) below, prepay the Loan prior to the next Interest Payment
Date, in whole or in part.

                  (b)      Each notice of prepayment of the Loan shall specify
the date and amount of such prepayment and shall be irrevocable. Each partial
prepayment of the Loan shall be in an aggregate principal amount which is the
lesser of $100,000.00 or an integral

                                      14
<PAGE>

multiple thereof. Interest on the amount prepaid accrued to the prepayment date
shall be paid on such date.

                  (c)      Upon prepayment of the Loan on a date other than the
relevant Interest Payment Date, Borrower shall pay to Bank, in addition to all
other payments then due and owing the Bank, premiums which shall be equal to an
amount, if any, reasonably determined by Bank to be the difference between the
rate of interest then applicable to the Loan and the yield Bank receives upon
reinvestment of so much of the Loan as is prepaid from the date of prepayment
until the end of such Interest Period. Anything in this Section 2.7(c) to the
contrary notwithstanding, the premiums payable upon any such prepayment shall
not exceed the amount, if any, reasonably determined by Bank to be the
difference between the rate of interest then applicable to the Loan and the
yield that Bank could receive upon reinvestment in the "Floor Reinvestment" of
so much of the Loan as is prepaid. For purposes hereof, "Floor Reinvestment"
shall mean an investment for the time period from the date of such prepayment
to the end of the current Interest Period applicable to the Loan at an interest
rate per annum equal to the Federal Fund Rate "offered" as published in the
Wall Street Journal on the date of such prepayment. All determinations,
estimates, assumptions, allocations and the like required for the determination
of such premiums shall be made by Bank in good faith and shall be presumed
correct absent demonstrable error.

                         SECTION 4. COLLATERAL SECURITY

         4.1      Composition of the Collateral. The property in which a
security interest is granted pursuant to the provisions of Paragraphs 4.2 and
4.3 is herein collectively called the "Collateral." The Collateral, together
with all of the Borrower's other property of any kind, both real and personal,
held by, assigned to, mortgaged to or conveyed in favor of the Bank, shall
stand as one general, continuing collateral security for all Obligations and
may be retained by the Bank until all Obligations have been satisfied in full.

         4.2      Rights in Property Held by the Bank. As security for the
prompt satisfaction of all Obligations and all Guaranties of the Obligations,
the Borrower hereby assigns, transfers and sets over to the Bank all of its
right, title and interest in and to, and grants the Bank a lien on and a
security interest in, all amounts that may be owing from time to time by the
Bank to the Borrower in any capacity, including, but without limitation, any
balance or share belonging to the Borrower of any deposit or other account with
the Bank, which lien and security interest shall be independent of any right of
set-off which the Bank may have.

         4.3      Rights in Property of the Borrower. As further security for
the prompt satisfaction of all Obligations, the Borrower hereby collaterally
assigns to the Bank all of its right, title and interest in and to, and grants
the Bank a lien upon and security interest in, all of the following, wherever
located, whether now owned or hereafter acquired, together with all
substitutions, replacements, improvements, accessions or appurtenances thereto,
and proceeds (including, without limitation, insurance proceeds) thereof:

                  (a)      Accounts;

                  (b)      Chattel Paper;

                  (c)      Documents;

                  (e)      General Intangibles;

                  (f)      Instruments;

                  (g)      Inventory; and

                  (h)      All Records pertaining thereto or to any other
Collateral; and

                  (i)      any other personal property, whether tangible or
intangible, now owned or hereafter acquired by Borrower.

         4.4      Priority of Liens. The foregoing liens shall be first and
prior liens except for any Permitted Liens on assets which have priority or
would have priority by the operation of Laws.

                                      17
<PAGE>

         4.5      Financing Statements.

                  (a)      The Borrower will:

                           (i)      Join with the Bank in executing such
         additional Financing Statements (including amendments thereto and
         continuation statements thereof) in form satisfactory to the Bank;

                           (ii)     pay or reimburse the Bank for all costs and
         taxes of filing or recording the same in such public offices as the
         Bank may designate, and reimburse the Bank for performing subsequent
         verification searches following Closing in each applicable
         jurisdiction.

                  (b)      A carbon, photographic, or other reproduction of
this Agreement shall be sufficient as a financing statement and may be filed in
any appropriate office in lieu thereof.

                  (c)      To the extent lawful, the Borrower hereby appoints
the Bank as its attorney-in-fact (without requiring the Bank to act as such) to
execute any Financing Statement in the name of the Borrower and to perform all
other acts that the Bank deems appropriate to perfect and continue the Bank's
security interest in, and to protect and preserve, the Collateral.

         4.6      Collection of Notes and Receivables. Following the occurrence
of any Event of Default and for so long as such Event of Default remains
uncured, upon demand of the Bank, Borrower shall deposit or cause to be
deposited, all checks, drafts, cash, and other remittances received in payment
of services rendered or in payment or on account of its accounts and notes
receivable, immediately upon receipt thereof with Bank in a special "lockboxed"
bank account maintained with Bank, over which the Bank alone shall have power
or withdrawal. The funds in said special bank account shall be held by the Bank
as security for all loans made hereunder and all other Obligations. Said
proceeds shall be deposited in precisely the form received, except for the
endorsement of Borrower where necessary to permit collection, which endorsement
Borrower agrees to make and which Bank also hereby is irrevocably authorized to
make on its behalf. Pending such deposit, Borrower agrees that it will not
commingle any such checks, drafts, cash and other remittances with any of its
funds or property, but will hold them separate and apart therefrom and upon an
express trust for the Bank until deposit thereof is made in the said special
bank account. On a daily basis, Bank will apply the whole or any part of the
collected funds on deposit in the said special bank account against the
principal and/or interest of any loans made hereunder and/or on Borrower's
other Obligation's secured hereby, the order and method of such application to
be in the discretion of the Bank. Any portion of said funds on deposit in the
special bank account that the Bank elects not to apply will be paid over by
Bank to Borrower.

                   SECTION 5. REPRESENTATIONS AND WARRANTIES

         To induce the Bank to enter into this Agreement, the Borrower and
Guarantor, jointly and severally, represent and warrant to Bank as follows:

to the best of Borrower's knowledge complied with the provisions of such

                  (l)      Any proceeding shall be instituted against the
Borrower or Guarantor, which is likely (taking into account the probability of
an adverse determination and the exhausting of all appeals) to have a Material
Adverse Effect, as determined by Bank in its reasonable discretion.

                  (m)      The Borrower or Guarantor shall default beyond any
applicable grace period in any other Indebtedness (excluding the Obligations)
owed to the Bank, or any of them, or under any other agreements for credit or
borrowed money it may have with Bank, jointly or severally, directly or
indirectly, whether matured or unmatured.

                  (n)      A Change of Control shall have occurred.

                  (o)      A change in the senior management of the Guarantor
which results in less than two of the four senior managers of the Borrower
continuing in the employ of the Borrower in the position set forth opposite
such person's name below and performing the duties traditionally associated
with such position. For purposes of this Agreement, the senior managers of the
Borrower, and the current respective capacities of each manager, are as
follows:

                  Charles N. Martin, Jr.          Director

                  William V.B. Webb               President and CEO

                  Charles T. Neal                 Chief Operating Officer

                  Jerry M. Eyler                  Chief Financial Officer

                  (p)      Violation by Borrower of any provision of any of the
Subordination Agreements.

         8.2      Acceleration. Upon the occurrence of any of such Events of
Default, the Bank may, at its option, immediately terminate the obligation to
make any further advances and/or declare the principal and interest accrued on
the Note and all other Obligations to be immediately due and payable, whereupon
the same shall become forthwith due and payable, without presentment, demand,
protest, or any notice of any kind except as set forth above; provided, that in
the case of the Events of Default specified in clause (g), (h) or (i) above
with respect to Borrower, without any notice to Borrower or any act by the
Bank, the Note and all other Obligations shall become immediately due and
payable without presentment, demand, protest or other notice of any kind, all
of which are waived by the Borrower. In addition, and regardless of whether the
Note has been accelerated, the Bank may upon the occurrence of any Event of
Default elect to charge interest at the Default Rate set forth in the Note.

         8.3      Remedies. After any acceleration, as provided for in
Paragraph 8.2, the Bank shall have, in addition to the rights and remedies
given it by the Loan Documents, all those allowed by all applicable Laws,
including, but without limitation, the UCC as enacted in any jurisdiction in
which any Collateral may be located. Without limiting the generality of the
foregoing, the Bank may immediately, without demand of performance and without
other notice (except as specifically required by the Loan Documents) or demand
whatsoever to the Borrower, all of which are hereby expressly waived, and
without advertisement, sell at public or private sale, in any manner and at any
location authorized by Laws, or otherwise realize upon, the whole, or, from
time to time, any part of the Collateral, or any interest which the Borrower
may have therein. After deducting from the proceeds of sale or other
disposition of the Collateral all expenses (including all reasonable expenses
for legal services), the Bank shall apply such proceeds toward the satisfaction
of the Obligations. Any remainder of the proceeds after satisfaction in full of
the Obligations shall be distributed as required by applicable Laws. Notice of
any sale or other disposition shall be given to the Borrower at least ten (10)
days before the time of any intended public sale or of the time after which any
intended private sale or other disposition of the Collateral is to be made,
which the Borrower hereby agrees shall be reasonable notice of such sale or
other disposition. The Borrower agrees to assemble, or to cause to be
assembled, at its own

                                      30
<PAGE>

expense, the Collateral at such place or places as the Bank shall designate. At
any such sale or other disposition, the Bank may, to the extent permissible
under applicable Laws, purchase the whole or any part of the Collateral, free
from any right of redemption on the part of the Borrower, which right is hereby
expressly waived and released.

                  Without limiting the generality of any of the rights and
remedies conferred upon the Bank under this Paragraph 8.3, the Bank may, to the
full extent permitted by applicable Laws:

                  (a)      Enter upon the premises of the Borrower, exclude
therefrom the Borrower, any Subsidiary or any officer or employee thereof, and
take immediate possession of the Collateral, either personally or by means of a
receiver appointed by a court of competent jurisdiction, using all necessary
and lawful self-help to do so;

                  (b)      At the Bank's option, use, operate, manage and
control the Collateral in any lawful manner;

                  (c)      Collect and receive all receivables, rents, income,
revenue, earnings, issues and profits therefrom; and

                  (d)      Maintain, repair, renovate, alter or remove the
Collateral as the Bank may determine in its discretion.

                            SECTION 9. MISCELLANEOUS

         9.1      Construction. The provisions of this Agreement shall be in
addition to those of any guaranty, pledge or security agreement, note or other
evidence of liability held by the Bank, all of which shall be construed as
complementary to each other; provided, in the event of any inconsistency, the
provisions of this Agreement shall control. Nothing herein contained shall
prevent the Bank from enforcing any or all other notes, guaranties, pledge or
security agreements in accordance with their respective terms.

         9.2      Further Assurance. From time to time, the Borrower and
Guarantor will execute and deliver to the Bank such additional documents and
will provide such additional information as the Bank may reasonably require to
carry out the terms of this Agreement and be informed of the Borrower's
operations, business and condition

         9.3      Enforcement and Waiver by the Bank. The Bank shall have the
right at all times to enforce the provisions of the Loan Documents in strict
accordance with the terms thereof, notwithstanding any conduct or custom on the
part of the Bank in refraining from so doing at any time or times. The failure
of the Bank at any time or times to enforce their rights under such provisions,
strictly in accordance with the same, shall not be construed as having created
a custom in any way or manner contrary to specific provisions of the Loan
Documents or as having in any way or manner modified or waived the same. All
rights and remedies of the Bank is cumulative and concurrent and the exercise
of one right or remedy shall not be deemed a waiver or release of any other
right or remedy.

                                      31

         9.4      Expenses of the Bank. The Borrower will, on demand, reimburse
the Bank for all out-of-pocket expenses, including the reasonable fees and
expenses of legal counsel for the Bank, incurred by the Bank in connection with
the preparation, administration, amendment, modification, or enforcement of the
Loan Documents and the collection or attempted collection of the Note.

         9.5      Notices. Any notices or consents required or permitted by
this Agreement shall be in writing and shall be deemed delivered when delivered
in person, or when sent by certified mail, postage prepaid, return receipt

reason, Borrower hereby agrees to make the maximum contribution to the payment
and satisfaction of such liabilities and costs permitted under applicable Laws.

         9.8      Applicable Laws. The Laws of the State of Tennessee, other
than its conflicts of laws rules, shall govern the construction and
interpretation of this Agreement and the validity and enforceability of this

Agreement, except for those transactions for which the parties have chosen
other laws to govern or for which other mandatory choice of law rules apply.

         9.9      Binding Effect, Assignment and Entire Agreement. This
Agreement shall inure to the benefit of, and shall be binding upon, the
respective successors and permitted assigns of the parties hereto. The Borrower
has no right to assign any of its rights or obligations hereunder without the
prior written consent of the Bank. This Agreement and the documents executed
and delivered pursuant hereto constitute the entire agreement between the
parties, and supersede all prior agreements and understandings among the
parties hereto. This Agreement may be amended only by a writing signed on
behalf of each party.

         9.10     Severability. If any provision of this Agreement shall be
held invalid under any applicable Laws, such invalidity shall not affect any
other provision of this Agreement that can be given effect without the invalid
provision, and, to this end, the provisions hereof are severable.

         9.11     Counterparts. This Agreement may be executed by the parties
independently in any number of counterparts, all of which together shall
constitute but one and the same instrument which is valid and effective as if
all parties had executed the same counterpart.

         9.12     Venue. It is agreed that venue for any action arising in
connection with this Agreement or the Obligations secured hereby shall lie
exclusively with courts sitting in the State of Tennessee, unless the Bank
otherwise agrees in writing.

         9.13     Arbitration. Any controversy or claim between or among the
parties hereto including, but not limited to, those arising out of or relating
to this instrument, agreement or document or any related instruments,
agreements or documents, including any claim based on or arising from an
alleged tort, shall be determined by binding arbitration in accordance with the
Federal Arbitration Act (or if not applicable, the applicable state law), the
Rules of Practice and Procedure for the Arbitration of Commercial Disputes of

                                      33
<PAGE>

J.A.M.S./Endispute or any successor thereof ("J.A.M.S."), and the "Special
Rules" set forth below. In the event of any inconsistency, the Special Rules
shall control. Judgment upon any arbitration award may be entered in any court
having jurisdiction. Any party to this Agreement may bring an action, including
a summary or expedited proceeding, to compel arbitration of any controversy or
claim to which this Agreement applies in any court having jurisdiction over
such action.

                  (a)      Special Rules. The arbitration shall be conducted in
the city of the Borrower's domicile at time of the execution of this
instrument, agreement or document and administered by J.A.M.S. who will appoint
an arbitrator; if J.A.M.S. is unable or legally precluded from administering
the arbitration, then the American Arbitration Association will serve. All
arbitration hearings will be commenced within 90 days of the demand for
arbitration; further, the arbitrator shall only, upon a showing of cause, be
permitted to extend the commencement of such hearing for up to an additional 60
days.

                  (b)      Reservation of Rights. Nothing in this arbitration
provision shall be deemed to (i) limit the applicability of any otherwise
applicable statutes of limitation or repose and any waivers contained in this
arbitration provision; or (ii) be a waiver by the Bank of the protection
afforded to it by 12 U.S.C. Sec. 91 or any substantially equivalent state law;
or (iii) limit the right of the Bank hereto (a) to exercise self help remedies
such as (but not limited to) setoff, or (b) to foreclose against any real or
personal property collateral, or (c) to obtain from a court provisional or
ancillary remedies such as (but not limited to) injunctive relief, writ of
possession or the appointment of a receiver. The Bank may exercise such self
help rights, foreclose upon such property, or obtain such provisional or
ancillary remedies before, during or after the pendency of any arbitration
proceeding brought pursuant to this instrument, agreement or document. Neither
this exercise of self help remedies nor the institution or maintenance of an
action for foreclosure or provisional or ancillary remedies shall constitute a
waiver of the right of any party, including the claimant in such action, to
arbitrate the merits of the controversy or claim occasioning resort to such
remedies.

         9.14     Right of Setoff. Borrower and Guarantor acknowledge that Bank
shall retain its common law right of setoff with respect to any of the
Obligations.
