         Section 7.9 Amendment. The power to alter, amend, or repeal these

         Section 7.10 Right to Indemnification.

         (A) Each person (hereinafter an "indemnitee") who was or is made a
party or is threatened to be made a party to or is otherwise involved in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), by reason of the fact that he or she
was a director, officer or agent of the corporation or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation or of a partnership, joint venture, trust or other enterprise,
including service with respect to an employee benefit plan, whether the basis of
such proceeding is alleged action in an official capacity as a director,
officer, employee or agent, shall be indemnified and held harmless by the
corporation to the fullest extent authorized by the Tennessee Code, as the same
exists or may hereafter be amended (but, in the case of any such amendment, only
to the extent that such amendment permits the corporation to provide broader
indemnification rights than permitted prior thereto), against all expense,
liability and loss (including attorney's fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith, and such indemnification
shall continue with respect to an indemnitee who has ceased to be a director,
officer, employee or .agent and shall inure to the benefit of the indemnitee's
heirs, executors and administrators; provided, however, that, except as provided
in paragraph (B) hereof with respect to proceedings to enforce rights to
indemnification, the corporation shall indemnify any such indemnitee only if
such proceeding (or part thereof) was authorized by the board of directors of
the corporation. The right to indemnification conferred in this section shall be
a contract right and shall include the right to be paid by the corporation the
expenses incurred in defending any such proceeding in advance of its final
disposition (hereinafter an "advancement of expenses"); provided, however, that,
if the Tennessee Code requires, an advancement of expenses incurred by an
indemnitee shall be made only upon delivery to the corporation of an undertaking
(hereinafter an "undertaking"), by or on behalf of such indemnitee, to repay all
amounts so advanced if it shall ultimately be determined by final judicial
decision from which there is no further right to appeal (hereinafter a "final
adjudication") that such indemnitee is not entitled to be indemnified for such
expenses under this section or otherwise.


                                       9



         (B) If a claim under paragraph (A) of this section is not paid in full
by the corporation within 60 days after a written claim has been received by the
corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be 20 days, the indemnitee may at any
time thereafter bring suit against the corporation to recover the unpaid amount
of such suit, or in a suit brought by the corporation to recover an advancement
of expenses pursuant to the terms of an undertaking, the indemnitee shall be
entitled to be paid also the expense of prosecuting or defending such suit. In
(i) any suit brought by the indemnitee to enforce a right to indemnification
hereunder (but not in a suit brought by the indemnitee to enforce a right to an
advancement of expenses) it shall be a defense that, and (ii) any suit by the
corporation to recover an advancement of expenses pursuant to the terms of an
undertaking the corporation shall be entitled to recover such expenses upon a
final adjudication that, the indemnitee has not met the applicable standard of
conduct set forth in the Tennessee Code. Neither the failure of the corporation
(including its board of directors, independent legal counsel, or its
shareholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Tennessee Code, nor an actual determination by the corporation (including
its board of directors, independent legal counsel, or its shareholders) that the
indemnitee has not met such applicable standard of conduct shall create a
presumption that the indemnitee has not met the applicable standard of conduct
or, in the case of such a suit brought by the indemnitee, be a defense of such
suit. In any suit brought by the indemnitee to enforce a right of
indemnification or to an advancement of expenses hereunder, or by the
corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the burden of proving that the indemnitee is not entitled to be
indemnified, or to such advancement of expenses, under this section or otherwise
shall be on the corporation.

         (C) The rights to indemnification and to the advancement of expenses
conferred in this section shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, the corporation's
certificate of incorporation, by agreement, by vote of shareholders or by
disinterested directors or otherwise.

         (D) The corporation may maintain insurance, at its expense, to protect
itself and any director, officer, employee or agent of the corporation or
another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the corporation would
have the power to indemnify such person against such expense, liability or loss
under the Tennessee Code.

         Section 7.11 Invalid Provisions. If any provision of these bylaws is
held to be illegal, invalid, or unenforceable under present or future laws, such
provision shall


                                       10


be fully severable; these bylaws shall be construed and enforced as if such
illegal, invalid, or unenforceable provision had never comprised a part hereof;
and the remaining provisions hereof shall remain in full force and effect and
shall not be affected by the illegal, invalid, or unenforceable provision or by
its severance herefrom. Furthermore, in lieu of such illegal, invalid, or
unenforceable provision there shall be added automatically as a part of these
bylaws a provision as similar in terms to such illegal, invalid, or
unenforceable provision as may be possible and be legal, valid, and enforceable.

         Section 7.12 Headings. The headings used in these bylaws are for
reference purposes only and do not affect in any way the meaning or
interpretation of these bylaws.

effective as of the 4th day of April, 1995.
