  2. No Ownership Interest. Nothing contained in this Agreement shall be
deemed to vest in Parent any direct or indirect ownership or incidence of
ownership of or with respect to any Shares. All rights, ownership, and economic
benefits of and relating to the Shares shall remain vested in and belong to
Stockholder.  Parent shall have no authority to manage, direct, superintend,
restrict, regulate, govern, or administer any of the policies or operations of
the Company or exercise any power or authority to direct Stockholder in the
voting of any of the Shares, except as otherwise provided herein, or in the
performance of the Stockholder's duties or responsibilities as a stockholder of
the Company.

  3. No Inconsistent Agreements. Stockholder hereby covenants and agrees
that, except as contemplated by this Agreement and the Merger Agreement, the
Stockholder (i) has not entered, and shall not enter at any time while this
Agreement remains in effect, into any voting agreement or voting trust with
respect to the Shares and (ii) has not granted, and shall not grant at any time
while this Agreement remains in effect, a proxy, power of attorney, or any
similar agreement with respect to the Shares, in either case, which is
inconsistent with such Stockholder's obligations pursuant to this Agreement.

  4. Authorization; Validity of Agreement; Necessary Action.  Stockholder has
full power and authority to execute and deliver this Agreement, to perform
Stockholder's obligations hereunder, and to consummate the transactions
contemplated hereby. This Agreement has been duly executed and delivered by
Stockholder, and, assuming this Agreement constitutes a valid and binding
obligation of Parent and Merger Sub, constitutes a valid and binding obligation
of Stockholder, enforceable against him in accordance with its terms.

  5. Adjustments. In the event of a stock dividend or distribution, or any
change in the Company Shares by reason of any stock dividend, split-up,
recapitalization, combination, exchange of shares, or the like, the term
"Shares" shall be deemed to refer to and include the Shares as well as all such
stock dividends and distributions and any shares into which or for which any or
all of the Shares may be changed or exchanged. Stockholder shall be entitled to
receive any cash dividend paid by the Company during the term of this Agreement.

  6. Termination. This Agreement shall terminate and no party shall have any
rights or duties hereunder upon the earlier of (a) the Effective Time or (b)
termination of the Merger Agreement. Nothing in this Section 7 shall relieve or
otherwise limit any party of liability for breach of this Agreement.

  7. Capacity. The obligations of Stockholder herein are made only in his
capacity as a stockholder of the Company.

  8. Notices. All notices or other communications which are required or
permitted hereunder shall be in writing and sufficient if delivered personally
or sent by nationally recognized overnight courier or by registered or certified
mail, postage prepaid, return receipt requested, or by electronic mail, with a
copy thereof to be delivered or sent as provided above or by facsimile or
telecopier. All such notices or communications shall be deemed to be received
(i) in the case of personal delivery, nationally recognized overnight courier,
or registered or certified

mail, on the date of such delivery and (ii) in the case of facsimile or
telecopier or electronic mail, upon confirmed receipt.

  9. Severability. If any term or other provision of this Agreement is
invalid, illegal, or incapable of being enforced by any rule of Law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner adverse to
any party. Upon such determination that any term or other provision is invalid,
illegal, or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that
transactions contemplated hereby are fulfilled to the extent possible.

  10. Amendments; Assignment. This Agreement may not be amended except by
written agreement by all the parties. This Agreement shall be binding upon and
inure to the benefit of the parties and their respective successors and
permitted assigns. Neither this Agreement nor any of the rights, interests, or
obligations under this Agreement shall be assigned, in whole or in part, by any
of the parties without the prior written consent of the other parties, and any
purported assignment without such consent shall be void.

  11. Failure or Indulgence Not Waiver; Remedies Cumulative. No failure or
delay on the part of any party hereto in the exercise of any right hereunder
will impair such right or be construed to be a waiver of, or acquiescence in,
any breach of any representation, warranty, or agreement herein, nor will any
single or partial exercise of any such right preclude other or further exercise
thereof or of any other right. All rights and remedies existing under this
Agreement are cumulative to, and not exclusive to, and not exclusive of, any
rights or remedies otherwise available.

12. Entire Agreement. This Agreement constitutes the entire agreement
between Parent, Merger Sub, and Stockholder with respect to the subject matter
hereof and supersedes all prior agreements and understandings, both written and
oral, between Parent, Merger Sub, and Stockholder with respect to the subject
matter hereof.

  13. Counterparts. This Agreement may be executed in one or more
counterparts, and by the different parties hereto in separate counterparts, each
of which when executed shall be deemed to be an original, but all of which taken
together shall constitute one and the same agreement.

  14. Governing Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Tennessee applicable to contracts
executed in and to be performed entirely within that state.

  15. Specific Performance. The parties hereto agree that irreparable damage
would occur in the event any provision of this Agreement is not performed in
accordance with the terms hereof, and that the parties shall be entitled to
specific performance of the terms hereof, in addition to any other remedy at law
or in equity.
