         The preferences, limitations, and relative rights of the above

<PAGE>

         (1) Common Stock. There shall be one class of Common Stock. Set forth
below in this Section (1) of Article 7 is a statement of the designations and
the powers, preferences and rights, and the qualifications, limitations or
restrictions thereof. All subsection references contained herein shall be to
this Section (1) of Article 7.

                  (a) Voting. Except as required by law and subject to any
         voting rights provided to holders of Series C Preferred Stock by this
         Charter, at every meeting of shareholders of the Corporation, every
         holder of Common Stock shall be entitled to one vote, in person or by
         proxy, for each share of Common Stock standing in such holder's name on
         the stock transfer records of the Corporation.

                  (b) Distribution of Assets. If the Corporation shall be
         liquidated, dissolved or wound up, whether voluntarily or
         involuntarily, the holders of the Common Stock shall be entitled to an
         equal amount of net assets for each share of Common Stock. A merger or
         consolidation of the Corporation with or into any other corporation or
         sale or conveyance of all or any part of the assets of the Corporation
         (which shall not in fact result in the liquidation of the Corporation
         and the distribution of assets to shareholders) shall not be deemed to
         be a voluntary or involuntary liquidation or dissolution or winding up
         of the Corporation within the meaning of this Subsection (b).

                  (c) Dividends; Distributions. Holders of Common Stock shall be
         entitled to receive, on an equal basis, such dividends, payable in cash
         or otherwise, as may be declared thereon by the Board of Directors from
         time to time out of the assets or funds of the Corporation legally
         available therefor.

                  (d) Amendment or Modification. None of the powers, preferences
         and relative rights of the Common Stock as provided herein shall be
         amended in any manner which would alter or change the powers,
         preferences and relative rights of the holders of Common Stock so as to
         adversely affect them without being approved by the holders of the
         Common Stock.

         (2) Series C Junior Participating Preferred Stock. Pursuant to the
authority vested in the Board of Directors in accordance with the provisions of
this Article 7 of the Charter, the Board of Directors does hereby create,
authorize and provide for the issuance of the Series C Junior Participating
Preferred Stock out of the class of 5,000,000 shares of Preferred Stock, having
the voting powers, designation, relative, participating, optional and other
special rights, preferences, and qualifications, limitations and restrictions
thereof that are set forth as follows:

                  (a) Designation and Amount. The shares of such series shall be
         designated as Series C Junior Participating Preferred Stock ("Series C
         Preferred Stock") and the number of shares constituting such series
         shall be 398,000. Such number of shares may be adjusted by appropriate
         action of the Board of Directors.

                  (b) Dividends and Distributions. Subject to the prior and
         superior rights of the holders of any shares of any other series of
         Preferred Stock or any other shares of Preferred Stock of the
         Corporation ranking prior and superior to the shares of Series C

                                       2
<PAGE>

         Preferred Stock with respect to dividends, each holder of one
         one-hundredth (1/100) of a share (a "Unit") of Series C Preferred Stock
         shall be entitled to receive, when, as and if declared by the Board of
         Directors out of funds legally available for that purpose, dividends at
         the same rate as dividends are paid with respect to the Common Stock.
         In the event that the Corporation shall at any time after November 19,
         1999 (the "Rights Dividend Declaration Date") (i) declare or pay any
         dividend on outstanding shares of Common Stock payable in shares of
         Common Stock; (ii) subdivide outstanding shares of Common Stock; or
         (iii) combine outstanding shares of Common Stock into a smaller number
         of shares, then in each such case the amount to which the holder of a
         Unit of Series C Preferred Stock was entitled immediately prior to such
         event pursuant to the preceding sentence shall be adjusted by
         multiplying such amount by a fraction the numerator of which shall be
         the number of shares of Common Stock that are outstanding immediately
         after such event and the denominator of which shall be the number of
         shares of Common Stock that were outstanding immediately prior to such
         event.

                  (c) Voting Rights. The holders of Units of Series C Preferred
         Stock shall have the following voting rights:

                           (i) Subject to the provision for adjustment
                  hereinafter set forth, each Unit of Series C Preferred Stock
                  shall entitle the holder thereof to one vote on all matters
                  submitted to a vote of the shareholders of the Corporation. In
                  the event the Corporation shall at any time after the Rights
                  Dividend Declaration Date (i) declare any dividend on
                  outstanding shares of Common Stock payable in shares of Common
                  Stock; (ii) subdivide outstanding shares of Common Stock; or
                  (iii) combine the outstanding shares of Common Stock into a
                  smaller number of shares, then in each such case the number of
                  votes per Unit to which holders of Units of Series C Preferred
                  Stock were entitled immediately prior to such event shall be
                  adjusted by multiplying such number by a fraction the
                  numerator of which shall be the number of shares of Common
                  Stock that are outstanding immediately after such event and
                  the denominator of which shall be the number of shares of
                  Common Stock that were outstanding immediately prior to such
                  event.

                           (ii) Except as otherwise provided herein or by law,
                  the holders of Units of Series C Preferred Stock and the
                  holders of shares of Common Stock shall vote together as one
                  class on all matters submitted to a vote of shareholders of
                  the Corporation.

                           (iii) Except as set forth herein or required by law,
                  holders of Units of Series C Preferred Stock shall have no
                  special voting rights and their consent shall not be required
                  (except to the extent they are entitled to vote with holders
                  of shares of Common Stock as set forth herein) for the taking
                  of any corporate action.

                  (d) Reacquired Shares. Any Units of Series C Preferred Stock
         purchased or otherwise acquired by the Corporation in any manner
         whatsoever shall be retired and

                                       3
<PAGE>

         cancelled promptly after the acquisition thereof. All such Units shall,
         upon their cancellation, become authorized but unissued Units of Series
         C Preferred Stock to be created by resolution or resolutions of the
         Board of Directors, subject to the conditions and restrictions on
         issuance set forth herein.

                  (e) Liquidation. Upon any liquidation, dissolution or winding
         up of the Corporation, whether voluntary or involuntary, the holders of
         Units of Series C Preferred Stock shall be entitled to share in any
         assets remaining ratably with the holders of the Common Stock. In the
         event the Corporation shall at any time after the Rights Dividend
         Declaration Date (i) increase by way of stock split or similar
         transaction the number of outstanding shares of Common Stock; (ii)
         subdivide the outstanding shares of Common Stock; or (iii) combine the
         outstanding shares of Common Stock into a smaller number of shares,
         then in each such case the aggregate amount to which holders of Units
         of Series C Preferred Stock were entitled prior to such event shall be
         adjusted by multiplying such amount by a fraction, the numerator of
         which shall be the number of shares of Common Stock that are
         outstanding immediately after such event and the denominator of which
         shall be the number of shares of Common Stock that were outstanding
         immediately prior to such event.

                  (f) Share Exchange, Merger, Etc. In case the Corporation shall
         enter into any share exchange, merger, combination or other transaction
         in which the shares of Common Stock are exchanged for or converted into
         other stock or securities, cash and/or any other property, then in any
         such case Units of Series C Preferred Stock shall at the same time be
         similarly exchanged for or converted into an amount per Unit (subject
         to the provision for adjustment hereinafter set forth) equal to the
         aggregate amount of stock, securities, cash and/or any other property
         (payable in kind), as the case may be, into which or for which each
         share of Common Stock is converted or exchanged. In the event the
         Corporation shall at any time after the Rights Dividend Declaration
         Date (i) declare any dividend on outstanding shares of Common Stock
         payable in shares of Common Stock; (ii) subdivide outstanding shares of
         Common Stock; or (iii) combine outstanding shares of Common Stock into
         a smaller number of shares, then in each such case the amount set forth
         in the immediately preceding sentence with respect to the exchange or
         conversion of Units of Series C Preferred Stock shall be adjusted by
         multiplying such amount by a fraction the numerator of which shall be
         the number of shares of Common Stock that are outstanding immediately
         after such event and the denominator of which shall be the number of
         shares of Common Stock that were outstanding immediately prior to such
         event.

                  (g) Redemption. The Units of Series C Preferred Stock shall
         not be redeemable at the option of the Corporation or any holder
         thereof. Notwithstanding the foregoing sentence of this Section, the
         Corporation may acquire Units of Series C Preferred Stock in any other
         manner permitted by law and the Charter or Bylaws of the Corporation.

                  (h) Ranking. The Units of Series C Preferred Stock shall rank
         junior to any other class or series of Preferred Stock that hereafter
         may be issued by the Corporation as

                                       4
<PAGE>

         to the payment of dividends and the distribution of assets, unless the
         terms of any such series or class shall provide otherwise.

                  (i) Amendment. The Charter, including without limitation the
         provisions hereof, shall not hereafter be amended, either directly or
         indirectly, or through merger or share exchange with another
         corporation, in any manner that would alter or change the powers,
         preferences or special rights of the Series C Preferred Stock so as to
         affect the holders thereof adversely without the affirmative vote of
         the holders of a majority or more of the outstanding Units of Series C
         Preferred Stock, voting separately as a class.

                  (j) Fractional Shares. The Series C Preferred Stock may be
         issued in Units or other fractions of a share, which Units or fractions
         shall entitle the holder, in proportion to such holder's fractional
         shares, to exercise voting rights, receive dividends, participate in
         distributions and to have the benefit of all other rights of holders of
         Series C Preferred Stock.

         8. The shareholders of the Corporation shall not have preemptive
rights.

         9. All corporate powers shall be exercised by or under the authority
of, and the business and affairs of the Corporation shall be managed under the
direction of, a Board of Directors consisting of not less than three nor more
than twelve directors, the exact number of Directors to be determined in the
manner provided in the Bylaws of the Corporation. The Board of Directors shall
be divided into three classes, designated Class I, Class II and Class III. Each
class shall consist, as nearly as possible, of one-third of the total number of
Directors constituting the entire Board of Directors. Each class of Directors
shall be elected for a three-year term, except at the 1997 annual meeting of
shareholders, Class I Directors shall be elected for a one-year term; Class II
Directors shall be elected for a two-year term; and Class III Directors shall be
elected for a three-year term. If the number of Directors is changed, any
increase or decrease shall be apportioned among the classes so as to maintain
the number of Directors in each class as nearly equal as possible, and any
additional Director of any class elected to fill a vacancy resulting from an
increase in such class shall hold office for a term that shall coincide with the
remaining term of that class, but in no case will a decrease in the number of
Directors shorten the term of any incumbent Director. A Director shall hold
office until the annual meeting for the year in which his term expires and until
his successor shall be elected and qualify, subject, however, to prior death,
resignation, retirement, disqualification or removal from office.

            A Director may be removed from office but only for "cause" by the
affirmative vote of the holders of a majority of the voting power of the shares
entitled to vote for the election of Directors, considered for this purpose as
one class. "Cause" shall be defined for purposes of this Article 9 as (i) a
felony conviction of a Director or the failure of a Director to contest
prosecution for a felony; (ii) conviction of a crime involving moral turpitude;
or (iii) willful and continued misconduct or gross negligence by a Director in
the performance of his duties as a director.

            Notwithstanding any other provisions of this Charter, the
affirmative vote of holders of two-thirds of the voting power of the shares
entitled to vote at an election of Directors

                                       5
<PAGE>

shall be required to amend, alter, change or repeal, or to adopt any provisions
as part of this Charter or as part of the Corporation's Bylaws inconsistent with
the purpose and intent of this Article 9.

         10. To the fullest extent permitted by the Tennessee Business
Corporation Act as in effect on the date hereof and as hereafter amended from
time to time, a Director of the Corporation shall not be liable to the
Corporation or its shareholders for monetary damages for breach of fiduciary
duty as a director. If the Tennessee Business Corporation Act or any successor
statute is amended after adoption of this provision to authorize corporate
action further eliminating or limiting the personal liability of directors, then
the liability of a Director of the Corporation shall be eliminated or limited to
the fullest extent permitted by the Tennessee Business Corporation Act, as so
amended from time to time, or such successor statute. Any repeal or modification
of this Article 10 by the shareholders of the Corporation shall not affect
adversely any right or protection of a Director of the Corporation existing at
the time of such repeal or modification or with respect to events occurring
prior to such time.

         11. The Corporation shall indemnify every person who is or was a party
or is or was threatened to be made a party to any action, suit, or proceeding,
whether civil, criminal, administrative, or investigative, by reason of the fact
that he or she is or was a director, medical director or officer or is or was
serving at the request of the Corporation as a director, medical director,
officer, employee, agent, or trustee of another corporation or of a partnership,
joint venture, trust, employee benefit plan, or other enterprise, including
service on a committee formed for any purpose (and, in each case, his or her
heirs, executors, and administrators), against all expense, liability, and loss
(including counsel fees, judgments, fines, ERISA excise taxes, penalties, and
amounts paid in settlement) actually and reasonably incurred or suffered in
connection with such action, suit, or proceeding, to the fullest extent
permitted by applicable law, as in effect on the date hereof and as hereafter
amended. Such indemnification shall include advancement of expenses prior to the
final disposition of such action, suit, or proceeding, subject to the provision
of any applicable statute.

            The indemnification and advancement of expenses provisions of this
Article 11 shall not be exclusive of any other right that any person (and his or
her heirs, executors, and administrators) may have or hereafter acquire under
any statute, this Charter, the Corporation's Bylaws, resolution adopted by the
shareholders, resolution adopted by the Board of Directors, agreement, or
insurance, purchased by the Corporation or otherwise, both as to action in his
or her official capacity and as to action in another capacity. The Corporation
is hereby authorized to provide for indemnification and advancement of expenses
through its Bylaws, resolution of shareholders, resolution of the Board of
Directors, or agreement, in addition to that provided by this Charter.

         12. The Bylaws of this Corporation may be amended, altered, modified,
or repealed by resolution adopted by the Board of Directors, subject to any
provisions of law then applicable.

         13. The Corporation shall hold a special meeting of shareholders only
in the event (a) of a call of the Board of Directors of the Corporation or the
officers authorized to do so by the Bylaws of the Corporation, or (b) the
holders of at least fifteen (15%) percent of the voting

one or more written demands for the meeting describing the purpose or purposes
for which it is to be held.

         2.1 ANNUAL MEETING.

         An annual meeting of the shareholders of the Corporation shall be held
on such date as may be determined by the Board of Directors. The business to be

business as shall be properly brought before the meeting.

         2.2 SPECIAL MEETINGS.

         2.4 NOTICE OF MEETINGS; WAIVER.

                  (a) NOTICE. Notice of the date, time and place of each annual
and special shareholders' meeting and, in the case of a special meeting, a
description of the purpose or purposes for which the meeting is called, shall be
given no fewer than ten (10) days nor more than two (2) months before the date

                  (b) WAIVER. A shareholder may waive any notice required by
law, the Corporation's Amended and Restated Charter (the "Charter") or these
Bylaws before or after the date and time stated in such notice. Except as
provided in the next sentence, the waiver must be in writing, be signed by the
shareholder entitled to the notice and be delivered to the Corporation for

attendance at a meeting: (1) waives objection to lack of notice or defective
notice of the meeting, unless the shareholder at the beginning of the meeting
(or promptly upon his arrival) objects to holding the meeting or transacting
business at the meeting; and (2) waives objection

                                        2

<PAGE>

to consideration of a particular matter at the meeting that is not within the
purpose or purposes described in the meeting notice, unless the shareholder
objects to considering the matter when it is presented.

         2.5 RECORD DATE.

         The Board of Directors shall fix as the record date for the
determination of shareholders entitled to notice of a shareholders' meeting, to
demand a special meeting, to vote, or to take any other action, a date not more
than seventy (70) days before the meeting or action requiring a determination of
shareholders.

         A record date fixed for a shareholders' meeting is effective for any
adjournment of such meeting unless the Board of Directors fixes a new record
date, which it must do if the meeting is adjourned to a date more than four (4)
months after the date fixed for the original meeting.

         2.6 SHAREHOLDERS' LIST.

         After the record date for a meeting has been fixed, the Corporation
shall prepare an alphabetical list of the names of all shareholders who are
entitled to notice of a shareholders' meeting. Such list will show the address
of and number of shares held by each shareholder. The shareholders' list will be
available for inspection by any shareholder, beginning two (2) business days
after notice of the meeting is given for which the list was prepared and
continuing through the meeting, at the Corporation's principal office or at a
place identified in the meeting notice in the city where the meeting will be
held. A shareholder or his agent or attorney is entitled on written demand to
inspect and, subject to the requirements of the Tennessee Business Corporation
Act (the "Act"), to copy the list, during regular business hours and at his
expense, during the period it is available for inspection.

         2.7 VOTING GROUPS; QUORUM; ADJOURNMENT.

         All shares entitled to vote and be counted together collectively on a
matter at a meeting of shareholders shall be a "voting group". Shares entitled
to vote as a separate voting group may take action on a matter at a meeting only
if a quorum of those shares exists with respect to that matter. Except as
otherwise required by the Act or provided in the Charter, a majority of the
votes entitled to be cast on a matter by a voting group constitutes a quorum of
that voting group for action on that matter.

         Once a share is represented for any purpose at a meeting, it is deemed
present for quorum purposes for the remainder of the meeting and for any
adjournment of that meeting unless a new record date is or must be set for that
adjourned meeting.

         If a quorum of a voting group shall not be present or represented at
any meeting, the shares entitled to vote thereat shall have power to adjourn the
meeting to a different date, time or place without notice other than
announcement at the meeting of the new time, date or place to which the meeting
is adjourned. At any adjourned meeting at which a quorum of any voting group
shall be present or represented, any business may be transacted by such voting
group which might have been transacted at the meeting as originally called.

         2.8 VOTING OF SHARES.

         Unless otherwise provided by the Act or the Charter, each outstanding
share is entitled to one (1) vote on each matter voted on at a shareholders'
meeting. Only shares are entitled to vote. If a quorum exists, approval of
action on a matter (other than the election of directors) by a voting group
entitled to vote thereon is received if the votes cast within the voting group
favoring the action exceed the votes cast opposing the action, unless the
Charter or the Act requires a greater number of affirmative votes. Unless
otherwise provided in the Charter, directors are

                                        4

<PAGE>

elected by a plurality of the votes cast by the shares entitled to vote in the
election at a meeting at which a quorum is present.

         2.9 PROXIES.

         A shareholder may vote his or her shares in person or by proxy. A
shareholder may appoint a proxy to vote or otherwise act for him or her by
signing an appointment either personally or through an attorney-in-fact. An
appointment of a proxy is effective when received by the Secretary or other
officer or agent authorized to tabulate votes. An appointment is valid for
eleven (11) months unless another period is expressly provided in the
appointment form. An appointment of a proxy is revocable by the shareholder
unless the appointment form conspicuously states that it is irrevocable and the
appointment is coupled with an interest.

         2.10 ACCEPTANCE OF SHAREHOLDER DOCUMENTS.

         If the name signed on a shareholder document (a vote, consent, waiver,
or proxy appointment) corresponds to the name of a shareholder, the Corporation,
if acting in good faith, is entitled to accept such shareholder document and
give it effect as the act of the shareholder. If the name signed on such
shareholder document does not correspond to the name of a shareholder, the
Corporation, if acting in good faith, is nevertheless entitled to accept such
shareholder document and to give it effect as the act of the shareholder if:

                  (i) the shareholder is an entity and the name signed purports
         to be that of an officer or agent of the entity;

                  (ii) the name signed purports to be that of a fiduciary
         representing the shareholder and, if the Corporation requests, evidence
         of fiduciary status acceptable to the Corporation has been presented
         with respect to such shareholder document;

                                        5

<PAGE>

                  (iii) the name signed purports to be that of a receiver or
         trustee in bankruptcy of the shareholder and, if the Corporation
         requests, evidence of this status acceptable to the Corporation has
         been presented with respect to the shareholder document;

                  (iv) the name signed purports to be that of a pledgee,
         beneficial owner, or attorney-in-fact of the shareholder and, if the
         Corporation requests, evidence acceptable to the Corporation of the
         signatory's authority to sign for the shareholder has been presented
         with respect to such shareholder document; or

                  (v) two or more persons are the shareholder as co-tenants or
         fiduciaries and the name signed purports to be the name of at least one
         (1) of the co-owners and the person signing appears to be acting on
         behalf of all the co-owners.

         The Corporation is entitled to reject a shareholder document if the
Secretary or other officer or agent authorized to tabulate votes, acting in good
faith, has a reasonable basis for doubt about the validity of the signature on
such shareholder document or about the signatory's authority to sign for the
shareholder.

         2.11 ACTION WITHOUT MEETING.

         Action required or permitted by the Act to be taken at a shareholders'
meeting may be taken without a meeting. If all shareholders entitled to vote on
the action consent to taking such action without a meeting, the affirmative vote
of the number of shares that would be necessary to authorize or take such action
at a meeting is the act of the shareholders.

         The action must be evidenced by one (1) or more written consents
describing the action taken, at least one of which is signed by each shareholder
entitled to vote on the action in one (1)

                                        6

<PAGE>

or more counterparts, indicating such signing shareholder's vote or abstention
on the action and delivered to the Corporation for inclusion in the minutes or
for filing with the corporate records.

         If the Act or the Charter requires that notice of a proposed action be
given to nonvoting shareholders and the action is to be taken by consent of the
voting shareholders, then the Corporation shall give its nonvoting shareholders
written notice of the proposed action at least ten (10) days before such action
is taken. Such notice shall contain or be accompanied by the same material that
would have been required to be sent to nonvoting shareholders in a notice of a
meeting at which the proposed action would have been submitted to the
shareholders for action.

         2.12 PRESIDING OFFICER AND SECRETARY.

         Meetings of the shareholders shall be presided over by the Chairman of
the Board (the "Chairman"), or if the Chairman is not present or if the
Corporation shall not have a Chairman, by the President or Chief Executive
Officer, or if neither the Chairman nor the President or Chief Executive Officer
is present, by a chairman chosen by a majority of the shareholders entitled to
vote at such meeting. The Secretary or, in the Secretary's absence, an Assistant
Secretary shall act as secretary of every meeting, but if neither the Secretary
nor an Assistant Secretary is present, a majority of the shareholders entitled
to vote at such meeting shall choose any person present to act as secretary of
the meeting.

         2.13 NOTICE OF NOMINATIONS.

         Nominations for the election of directors may be made by the Board of
Directors or a committee appointed by the Board of Directors authorized to make
such nominations or by any shareholder entitled to vote in the election of
directors generally. However, any such shareholder nomination may be made only
if written notice of such nomination has been given, either by personal delivery
or the United States mail, postage prepaid, to the Secretary of the Corporation

                                        7

<PAGE>

not later than (a) with respect to an election to be held at an annual meeting
of shareholders, one hundred twenty (120) days in advance of the anniversary
date of the proxy statement for the previous year's annual meeting, and (b) with
respect to an election to be held at a special meeting of shareholders for the
election of directors called other than by written request of a shareholder, the
close of business on the tenth day following the date on which notice of such
meeting is first given to shareholders, and (c) in the case of a special meeting
of shareholders duly called upon the written request of a shareholder to fill a
vacancy or vacancies (then existing or proposed to be created by removal at such
meeting), within ten (10) business days of such written request. In the case of
any nomination by the Board of Directors or a committee appointed by the Board
of Directors authorized to make such nominations, compliance with the proxy
rules of the Securities and Exchange Commission shall constitute compliance with
the notice provisions of the preceding sentence.

         In the case of any nomination by a shareholder, each such notice shall
set forth: (a) as to each person whom the shareholder proposes to nominate for
election or re-election as a director, (i) the name, age, business address, and
residence address of such person, (ii) the principal occupation or employment of
such person, (iii) the class and number of shares of the Corporation which are
beneficially owned by such person, and (iv) any other information relating to
such person that is required to be disclosed in solicitations of proxies with
respect to nominees for election as directors, pursuant to Regulation 14A under
the Securities Exchange Act of 1934, as amended (including without limitation
such person's written consent to being named in the proxy statement as a nominee
and to serving as a director, if elected); and (b) as to the shareholder giving
the notice (i) the name and address, as they appear on the Corporation's books,
of such shareholder, and (ii) the class and number of shares of the Corporation
which are beneficially

                                        8

<PAGE>

owned by such shareholder; and (c) a description of all arrangements or
understandings between the shareholder and each nominee and any other person or
persons (naming such person or persons) pursuant to which the nomination or
nominations are to be made by the shareholder. The President, Chief Executive
Officer, or chairman of the meeting may refuse to acknowledge the nomination of
any person not made in compliance with the foregoing procedure.

         2.14 NOTICE OF NEW BUSINESS.

         At an annual meeting of the shareholders only such new business shall
be conducted, and only such proposals shall be acted upon, as have been properly
brought before the meeting. To be properly brought before the annual meeting
such new business must be (a) specified in the notice of meeting (or any
supplement thereto) given by or at the direction of the Board of Directors, (b)
otherwise properly brought before the meeting by or at the direction of the
Board of Directors, or (c) otherwise properly brought before the meeting by a
shareholder. For a proposal to be properly brought before an annual meeting by a
shareholder, the shareholder must have given timely notice thereof in writing to
the Secretary of the Corporation and the proposal and the shareholder must
comply with Rule 14a-8 under the Securities Exchange Act of 1934. To be timely,
a shareholder's notice must be delivered to or mailed and received at the
principal executive offices of the Corporation within the time limits specified
by Rule 14a-8.

         A shareholder's notice to the Secretary shall set forth as to each
matter the shareholder proposes to bring before the annual meeting (a) a brief
description of the proposal desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, (b) the name and
address, as they appear on the Corporation's books, of the shareholder proposing
such business, (c) the class and number of shares of the Corporation which are

                                        9

<PAGE>

beneficially owned by the shareholder, and (d) any financial interest of the
shareholder in such proposal.

         Notwithstanding anything in these Bylaws to the contrary, no business
shall be conducted at an annual meeting except in accordance with the procedures
set forth in this Section 2.14. The President, Chief Executive Officer, or
chairman of the meeting shall, if the facts warrant, determine and declare to
the meeting that new business or any shareholder proposal was not properly
brought before the meeting in accordance with the provisions of this Section
2.14, and if he or she should so determine, he or she shall so declare to the
meeting and any such business or proposal not properly brought before the
meeting shall not be acted upon at the meeting. This provision shall not prevent
the consideration and approval or disapproval at the annual meeting of reports
of officers, directors and committees, but in connection with such reports no
new business shall be acted upon at such annual meeting unless stated and filed
as herein provided.

         2.15 CONDUCT OF MEETINGS.

         Meetings of the shareholders generally shall follow accepted rules of
parliamentary procedure subject to the following:

                  (a) The President, Chief Executive Officer, or chairman of the
meeting shall have absolute authority over the matters of procedure, and there
shall be no appeal from the ruling of the President, Chief Executive Officer, or
chairman. If, in his or her absolute discretion, the President, Chief Executive
Officer, or chairman deems it advisable to dispense with the rules of
parliamentary procedure as to any meeting of shareholders or part thereof, he or
she shall so state and shall state the rules under which the meeting or
appropriate part thereof shall be conducted.

                                       10

<PAGE>

                  (b) If disorder should arise which prevents the continuation
of the legitimate business of the meeting, the President, Chief Executive
Officer, or chairman may quit the chair and announce the adjournment of the
meeting, and upon so doing, the meeting will immediately be adjourned.

                  (c) The President, Chief Executive Officer, or chairman may
ask or require that anyone not a bona fide shareholder or proxy leave the
meeting.

                  (d) The resolution or motion shall be considered for vote only
if proposed by a shareholder or a duly authorized proxy and seconded by a
shareholder or duly authorized proxy other than the individual who proposed the
resolution or motion.

                  (e) Except as the President, Chief Executive Officer, or
chairman may permit, no matter shall be presented to the meeting which has not
been submitted for inclusion in the agenda at least thirty (30) days prior to
the meeting.

                                  ARTICLE III.

                                    DIRECTORS

         3.1 POWERS AND DUTIES.

         All corporate powers shall be exercised by or under the authority of
and the business and affairs of the Corporation managed under the direction of
the Board of Directors.

         3.2 NUMBER AND TERM.

                  (a) NUMBER. The Board of Directors shall consist of no fewer
than three (3) or more than eleven (11) members. The exact number of directors,
within the minimum and maximum, or the range for the size of the Board, or
whether the size of the Board shall be fixed

                                       11

<PAGE>

or variable-range may be fixed, changed or determined from time to time by the
Board of Directors.

                  (b) TERM. The Board of Directors shall be divided into three
classes, designated Class I, Class II and Class III. Each class shall consist,
as nearly as possible, of one-third of the total number of directors
constituting the entire Board of Directors. Each class of directors shall be
elected for a three-year term, except at the 1997 annual meeting of
shareholders, Class I directors shall be elected for a one-year term; Class II
directors shall be elected for a two-year term; and Class III directors shall be
elected for a three-year term. If the number of directors is changed, any
increase or decrease shall be apportioned among the classes so as to maintain
the number of directors in each class as nearly equal as possible, and any
additional director of any class elected to fill a vacancy resulting from an
increase in such class shall hold office for a term that shall coincide with the
remaining term of that class, but in no case will a decrease in the number of
directors shorten the term of any incumbent director. A director shall hold
office until the annual meeting for the year in which his or her term expires
and until his or her successor shall be elected and shall qualify, subject,
however, to prior death, resignation, retirement, disqualification or removal
from office.

         3.3 MEETINGS; NOTICE.

         The Board of Directors may hold regular and special meetings either
within or without the State of Tennessee. The Board of Directors may permit any
or all directors to participate in a regular or special meeting by, or conduct
the meeting through the use of, any means of communication by which all
directors participating may simultaneously hear each other during

                                       12

<PAGE>

the meeting. A director participating in a meeting by this means is deemed to be
present in person at the meeting.

                  (a) REGULAR MEETINGS. Unless the Charter otherwise provides,
regular meetings of the Board of Directors may be held without notice of the
date, time, place, or purpose of the meeting.

                  (b) SPECIAL MEETINGS. Special meetings of the Board of
Directors may be called by the Chairman, the President, Chief Executive Officer,
or one-third of the entire Board of Directors. Unless the Charter otherwise
provides, special meetings must be preceded by at least twenty-four (24) hours'
notice of the date, time, and place of the meeting but need not describe the
purpose of such meeting. Such notice shall comply with the requirements of
Article XI of these Bylaws.

                  (c) ADJOURNED MEETINGS. Notice of an adjourned meeting need
not be given if the time and place to which the meeting is adjourned are fixed
at the meeting at which the adjournment is taken, and if the period of
adjournment does not exceed one (1) month in any one (1) adjournment.

                  (d) WAIVER OF NOTICE. A director may waive any required notice
before or after the date and time stated in the notice. Except as provided in
the next sentence, the waiver must be in writing, signed by the director, and
filed with the minutes or corporate records. A director's attendance at or
participation in a meeting waives any required notice to him or her of such
meeting unless the director at the beginning of the meeting (or promptly upon
his arrival) objects to holding the meeting or transacting business at the
meeting and does not thereafter vote for or assent to action taken at the
meeting.

                                       13

<PAGE>

         3.4 QUORUM.

         Unless the Charter requires a greater number, a quorum of the Board of
Directors consists of a majority of the fixed number of directors if the
Corporation has a fixed board size or a majority of the number of directors
prescribed, or if no number is prescribed, the number in office immediately
before the meeting begins, if the Corporation has a variable range board.

         3.5 VOTING.

         If a quorum is present when a vote is taken, the affirmative vote of a
majority of directors present is the act of the Board of Directors, unless the
Charter or these Bylaws require the vote of a greater number of directors. A
director who is present at a meeting of the Board of Directors when corporate
action is taken is deemed to have assented to such action unless:

                  (i) he or she objects at the beginning of the meeting (or
         promptly upon his or her arrival) to holding the meeting or transacting
         business at the meeting;

                  (ii) his or her dissent or abstention from the action taken is
         entered in the minutes of the meeting; or

                  (iii) he or she delivers written notice of his or her dissent
         or abstention to the presiding officer of the meeting before its
         adjournment or to the Corporation immediately after adjournment of the
         meeting. The right of dissent or abstention is not available to a
         director who votes in favor of the action taken.

         3.6 ACTION WITHOUT MEETING.

         Unless the Charter otherwise provides, any action required or permitted
by the Act to be taken at a Board of Directors meeting may be taken without a
meeting. If all directors consent to

                                       14

<PAGE>

taking such action without a meeting, the affirmative vote of the number of
directors that would be necessary to authorize or take such action at a meeting
is the act of the Board of Directors. Such action must be evidenced by one or
more written consents describing the action taken, at least one of which is
signed by each director, indicating the director's vote or abstention on the
action, which consents shall be included in the minutes or filed with the
corporate records reflecting the action taken. Action taken by consent is
effective when the last director signs the consent, unless the consent specifies
a different effective date.

         3.7 COMPENSATION.

         Directors and members of any committee created by the Board of
Directors shall be entitled to such reasonable compensation for their services
as directors and members of such committee as shall be fixed from time to time
by the Board, and shall also be entitled to reimbursement for any reasonable
expenses incurred in attending meetings of the Board or of any such committee
meetings. Any director receiving such compensation shall not be barred from
serving the Corporation in any other capacity and receiving reasonable
compensation for such other services.

         3.8 RESIGNATION.

         A director may resign at any time by delivering written notice to the
Board of Directors, the Chairman, President, or Chief Executive Officer, or to
the Corporation. A resignation is effective when the notice is delivered unless
the notice specifies a later effective date.

         3.9 VACANCIES.

         Unless the Charter otherwise provides, if a vacancy occurs on the Board
of Directors, including a vacancy resulting

                                       15

<PAGE>

from an increase in the number of directors or a vacancy resulting from the
removal of a director with or without cause, either the shareholders or the
Board of Directors may fill such vacancy. If the vacancy is filled by the
shareholders, it shall be filled by a plurality of the votes cast at a meeting
at which a quorum is present. If the directors remaining in office constitute
fewer than a quorum of the Board of Directors, they may fill such vacancy by the
affirmative vote of a majority of all the directors remaining in office. If the
vacant office was held by a director elected by a voting group of shareholders,
only the holders of shares of that voting group shall be entitled to vote to
fill the vacancy if it is filled by the shareholders.

         3.10 REMOVAL OF DIRECTORS.

                  (a) BY SHAREHOLDERS. The shareholders may remove one (1) or
more directors solely for cause as defined in the Charter. If cumulative voting
is authorized, a director may not be removed for cause if the number of votes
sufficient to elect him or her under cumulative voting is voted against his or
her removal. If cumulative voting is not authorized, a director may be removed
for cause only if the number of votes cast to remove him or her exceeds the
number of votes cast not to remove him or her.

                  (b) GENERAL. A director may be removed for cause by the
shareholders only at a meeting called for the purpose of removing him or her,
and the meeting notice must state that the purpose, or one (1) of the purposes,
of the meeting is removal of directors for cause.

         3.11 ELECTRONIC COMMUNICATION.

         Any one or more members of the Board of Directors or any committee
thereof may participate in a meeting of the Board of Directors or any such
committee by means of a conference telephone or similar communications equipment
allowing all persons participating in

                                       16

<PAGE>

the meeting to hear each other at the same time. Participation by such means
shall constitute presence in person at a meeting.

         3.12 CHAIRMAN OF THE BOARD.

         The Chairman of the Board shall be appointed from time to time by the
Board of Directors and shall preside at all meetings of the Board of Directors
and of the shareholders of the Corporation.

                                   ARTICLE IV.

                                   COMMITTEES

         Unless the Charter otherwise provides, the Board of Directors may
create one (1) or more committees, each consisting of one (1) or more members.
All members of committees of the Board of Directors which exercise powers of the
Board of Directors must be members of the Board of Directors and serve at the
pleasure of the Board of Directors.

         The creation of a committee and appointment of a member or members to
it must be approved by the greater of (i) a majority of all directors in office
when the action is taken or (ii) the number of directors required by the Charter
or these Bylaws to take action.

         Unless otherwise provided in the Act, to the extent specified by the
Board of Directors or in the Charter, each committee may exercise the authority
of the Board of Directors. All such committees and their members shall be
governed by the same statutory requirements regarding meetings, action without
meetings, notice and waiver of notice, quorum, and voting requirements as are
applicable to the Board of Directors and its members.

                                       17

<PAGE>

                                   ARTICLE V.

                                    OFFICERS

         5.1 NUMBER.

         The officers of the Corporation shall be a President, a Chief Executive
Officer, a Chief Financial Officer, a Secretary and such other officers as may
be from time to time appointed by the Board of Directors or by the Chairman or
Chief Executive Officer with the Board of Directors' approval. The Chairman may,
but need not be, an officer of the Corporation. One person may simultaneously
hold more than one office, except the President may not simultaneously hold the
office of Secretary.

         5.2 APPOINTMENT.

         The principal officers shall be appointed annually by the Board of
Directors at the first meeting of the Board following the annual meeting of the
shareholders, or as soon thereafter as is conveniently possible. Each officer
shall serve at the pleasure of the Board of Directors and until his or her
successor shall have been appointed, or until his or her death, resignation, or

         An officer may resign at any time by delivering notice to the
Corporation. Such resignation is effective when such notice is delivered unless
such notice specifies a later effective date. An officer's resignation does not
affect the Corporation's contract rights, if any, with the officer.

         The Board of Directors may remove any officer at any time with or
without cause, but such removal shall not prejudice the contract rights, if any,
of the person so removed.

                                 SHARES OF STOCK

         6.1 SHARES WITH OR WITHOUT CERTIFICATES.

         The Board of Directors may authorize that some or all of the shares of
any or all of the Corporation's classes or series of stock be evidenced by a
certificate or certificates of stock. The Board of Directors may also authorize
the issue of some or all of the shares of any or all of the Corporation's
classes or series of stock without certificates. The rights and obligations of
shareholders with the same class and/or series of stock shall be identical
whether or not their shares are represented by certificates.

                  (a) SHARES WITH CERTIFICATES. If the Board of Directors
chooses to issue shares of stock evidenced by a certificate or certificates,
each individual certificate shall include the following on its face: (i) the
Corporation's name, (ii) the fact that the Corporation is organized under the
laws of the State of Tennessee, (iii) the name of the person to whom the
certificate is issued, (iv) the number of shares represented thereby, (v) the
class of shares and the designation of the series, if any, which the certificate
represents, and (vi) such other information as applicable law may require or as
may be lawful.

                  If the Corporation is authorized to issue different classes of
shares or different series within a class, the designations, relative rights,
preferences, and limitations determined for each series (and the authority of
the Board of Directors to determine variations for future series) shall be
summarized on the front or back of each certificate. Alternatively, each
certificate shall state on its front or back that the Corporation will furnish
the shareholder this information in writing, without charge, upon request.

                                       22

<PAGE>

                  Each certificate of stock issued by the Corporation shall be
signed (either manually or in facsimile) by any two officers of the Corporation.
If the person who signed a certificate no longer holds office when the
certificate is issued, the certificate is nonetheless valid.

                  (b) SHARES WITHOUT CERTIFICATES. If the Board of Directors
chooses to issue shares of stock without certificates, the Corporation, if
required by the Act, shall, within a reasonable time after the issue or transfer
of shares without certificates, send the shareholder a written statement of the
information required on certificates by Section 6.1(a) of these Bylaws and any
other information required by the Act.

         6.2 SUBSCRIPTIONS FOR SHARES.

         Subscriptions for shares of the Corporation shall be valid only if they
are in writing. Unless the subscription agreement provides otherwise,
subscriptions for shares, regardless of the time when they are made, shall be
paid in full at such time, or in such installments and at such periods, as shall
be determined by the Board of Directors. All calls for payment on subscriptions
shall be uniform as to all shares of the same class or of the same series,
unless the subscription agreement specifies otherwise.

         6.3 TRANSFERS.

         Transfers of shares of the capital stock of the Corporation shall be
made only on the books of the Corporation by (i) the holder of record thereof,
(ii) his or her legal representative, who, upon request of the Corporation,
shall furnish proper evidence of authority to transfer, or (iii) his or her
attorney, authorized by a power of attorney duly executed and filed with the
Secretary of the Corporation or a duly appointed transfer agent. Such transfers
shall be made

                                       23

only upon surrender, if applicable, of the certificate or certificates for such
shares properly endorsed and with all taxes thereon paid.

         6.4 LOST, DESTROYED, OR STOLEN CERTIFICATES.

         No certificate for shares of stock of the Corporation shall be issued
in place of any certificate alleged to have been lost, destroyed, or stolen
except on production of evidence, satisfactory to the Board of Directors, of
such loss, destruction, or theft, and, if the Board of Directors so requires,
upon the furnishing of an indemnity bond in such amount and with such terms and
such surety as the Board of Directors may in its discretion require.

Officer, a Vice President or such other officer, assistant officer, or agent of

behalf of the Corporation to attend any meeting of security holders, or to take
action on written consent as a security holder, of other corporations in which
the Corporation may hold securities. In connection therewith the Chairman, the
