</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As permitted under Tennessee law, the Company&#146;s Charter provides that a director shall not be
personally liable to the Company or its shareholders for monetary damages for breach of fiduciary
duty as a director, except that such provision does not eliminate or limit the liability of a
director (a)&nbsp;for any breach of the director&#146;s duty of loyalty to the Company or its shareholders,
(b)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, or (c)&nbsp;for unlawful corporate distributions.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under its Bylaws, the Company may indemnify and advance expenses to its current and former
directors and officers with respect to certain liabilities incurred as a result of any threatened,
pending, or completed action, suit or proceeding, whether civil, criminal, administrative, or
investigative and whether formal or informal, to which such person is a party because he is or was
a director or officer of the Company. The liabilities that may be indemnified against include the
obligations to pay judgments, fines, penalties, amounts paid in settlement, and reasonable
expenses, including attorneys&#146; fees, incurred with respect to a proceeding. Any such
indemnification is predicated upon the proposed indemnitee having met the standard of conduct
specified in the Tennessee Business Corporation Act. Determination concerning whether or not the
applicable standard of conduct has been met can be made by (a)&nbsp;the Board of Directors by a majority
vote of a quorum consisting of disinterested directors, (b)&nbsp;a majority vote of a committee of
disinterested directors, (c)&nbsp;special legal counsel, or (d)&nbsp;an affirmative vote of a majority of
shares held by the disinterested shareholders. No indemnification shall be made to or on behalf of
a director (i)&nbsp;in connection with a proceeding by or in the right of the Company in which the
director was adjudged liable to the Company, or (ii)&nbsp;in connection with any other proceeding in
which the director was adjudged liable on the basis that personal benefit was improperly received
by him. The Company&#146;s Bylaws also permit the Company to indemnify or advance expenses to its
employees and agents to the same extent as to a director or officer.

permitted to directors, officers and controlling persons of the Company pursuant to Item&nbsp;6 of this
Part&nbsp;II, or otherwise, the Company has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid by a director,
officer or controlling person of the Company in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in connection with the
securities being registered, the Company will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate jurisdiction the question
whether such indemnification by it is against public policy as expressed in the Securities Act and
will be governed by the final adjudication of such issue.

Item 6. Indemnification of Directors and Officers.
As permitted under Tennessee law, the Company's Charter provides that a director shall not be
personally liable to the Company or its shareholders for monetary damages for breach of fiduciary
duty as a director, except that such provision does not eliminate or limit the liability of a
director (a) for any breach of the director's duty of loyalty to the Company or its shareholders,
(b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, or (c) for unlawful corporate distributions.
Under its Bylaws, the Company may indemnify and advance expenses to its current and former
directors and officers with respect to certain liabilities incurred as a result of any threatened,
pending, or completed action, suit or proceeding, whether civil, criminal, administrative, or
investigative and whether formal or informal, to which such person is a party because he is or was
a director or officer of the Company. The liabilities that may be indemnified against include the
obligations to pay judgments, fines, penalties, amounts paid in settlement, and reasonable
expenses, including attorneys' fees, incurred with respect to a proceeding. Any such
indemnification is predicated upon the proposed indemnitee having met the standard of conduct
specified in the Tennessee Business Corporation Act. Determination concerning whether or not the
applicable standard of conduct has been met can be made by (a) the Board of Directors by a majority
vote of a quorum consisting of disinterested directors, (b) a majority vote of a committee of
disinterested directors, (c) special legal counsel, or (d) an affirmative vote of a majority of
shares held by the disinterested shareholders. No indemnification shall be made to or on behalf of
a director (i) in connection with a proceeding by or in the right of the Company in which the
director was adjudged liable to the Company, or (ii) in connection with any other proceeding in
which the director was adjudged liable on the basis that personal benefit was improperly received
by him. The Company's Bylaws also permit the Company to indemnify or advance expenses to its
employees and agents to the same extent as to a director or officer.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits.
See Exhibit Index, which is incorporated here by reference.
Item 9. Undertakings.
(a) The undersigned Company hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:
(i) To include any prospectus required by section 10(a)(3) of the Securities Act;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the
registration statement (or the most recent post-effective amendment thereof) which, individually or
in the aggregate, represent a fundamental change in the information set forth in the registration
statement; and
(iii) To include any material information with respect to the plan of distribution not
previously disclosed in the registration statement or any material change in such information in
the registration statement.
Table of Contents
Provided, however,
that paragraphs (a)(l)(i) and (a)(l)(ii) above do not apply if the
registration statement is on Form S-8, and the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports filed by the Company
pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in
the registration statement.
(2) That, for the purpose of determining any liability under the Securities Act, each such
post-effective amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be
the initial
bona fide
offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.
(b) The Company hereby undertakes that, for purposes of determining any liability under the
Securities Act, each filing of the Company's annual report pursuant to Section 13(a) or Section
15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act that is incorporated by reference in the
registration statement) shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be
the initial
bona fide
offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the Company pursuant to Item 6 of this
Part II, or otherwise, the Company has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid by a director,
officer or controlling person of the Company in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in connection with the
securities being registered, the Company will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate jurisdiction the question
whether such indemnification by it is against public policy as expressed in the Securities Act and
will be governed by the final adjudication of such issue.
