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)&nbsp;for
any breach of the director'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.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">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)&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'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.</P>

as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons
of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the Commission
such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of such issue.</P>
