succeeding day not a holiday. In the event that the annual meeting is omitted by
oversight or otherwise on the date herein provided for, the directors shall
cause a meeting in lieu thereof to be held as soon thereafter as conveniently

      Section 3. Special Meetings. Except as otherwise provided by law, special
meetings of the shareholders of this corporation shall be held at such places
and times as may be determined by the President or by a majority of the Board of
Directors, or whenever one or more shareholders who

<PAGE>

are entitled to vote and who hold at least 10% of the common shares issued and

      Any meeting of which all shareholders entitled to vote have waived or at
any time shall waive notice in writing shall be a legal meeting for the
transaction of business, notwithstanding that notice has not been given as
hereinbefore provided.

      Section 5. Notice of Right to Dissent. If shareholders are to vote at a
meeting on a corporate action which would give rise to a dissenter's right to
payment for his shares in accordance with the Tennessee General Corporation Act,
notice of such meeting shall be given to every shareholder who will be entitled
to dissent from such action and to receive payment for his shares whether or not
entitled to vote thereon. Such notice shall be given in accordance with the
provisions of Section 4 of this Article and shall also contain a statement,
displayed with reasonable prominence, that upon compliance with the Tennessee
General Corporation Act, dissenting shareholders are entitled to be paid the
fair value of their shares as provided in said Act.

      Section 6. Closing of Transfer Books or Fixing of Record Date. For the
purpose of determining the shareholders entitled to notice of or to vote at any
meeting of shareholders or any adjournment thereof, or shareholders entitled to
receive payment of any dividend, or in order to make a


                                      - 4 -
<PAGE>

determination of shareholders for any other proper purpose, the Board of
Directors of the corporation may provide that the stock transfer book shall be
closed for a stated period not to exceed in any case thirty days. If the stock
transfer book shall be closed for the purpose of determining shareholders,
such books shall be closed for at least ten days immediately preceding such
meeting. In lieu of closing the stock transfer books, the Board of Directors may
fix in advance a date as the record date for any such determination of
shareholders, such date in any case to be not more than thirty days and, in case
of a meeting of shareholders, not less than ten days prior to the date on which
the particular action requiring such determination of shareholders is to be
taken. If the stock transfer books are not closed and no record date is fixed
for the determination of shareholders entitled to notice of or to vote at a
meeting of shareholders, or shareholders entitled to receive payment of a
dividend, the date on which notice of the meeting is mailed or the date on which
the resolution of the Board of Directors declaring such dividend is adopted, as
the case may be, shall be the record date for such determination of
shareholders. When a determination of shareholders entitled to vote at any
meeting of shareholders has been made as provided in this Section, such
determination shall apply to any adjournment thereof.

alphabetical order, with the address of and the number of shares held by each
shareholder, which list, for a period of ten days prior to such meeting shall be
kept on file at the registered office of the corporation and shall be subject to
inspection by any shareholder at any time during usual business hours. Such list
shall be certified by the corporate officer responsible for its preparation or
by the transfer agent and shall be produced and kept open at the time and
place of the meeting and be subject to the inspection of any shareholder during
the entire time of the meeting. In the event of any challenge to the right of
any person to vote at the meeting, the presiding officer at such meeting may
rely on said list as proper evidence of the right of parties to vote at such
meeting.

      Section 8. Quorum. Except as may be otherwise provided by law, a majority
of the outstanding shares of the corporation entitled to vote, represented in
person or by proxy, shall constitute a quorum at a meeting of shareholders. In
the event that less than a majority of the outstanding shares are represented at
any meeting, a majority of the


                                      - 6 -

shares represented thereat entitled to vote shall decide any question brought
before such meeting, unless the question is one upon which by express provision
of law or of the certificate of incorporation or of these by-laws a larger or
different vote is required, in which case such express provision shall govern
and control the decision of each question.

      Section 9. Proxies. Shareholders of record who are entitled to vote may
vote at any meeting either in person or by proxy in writing, which shall be
filed with the Secretary of the meeting before being voted. Such proxy shall
entitle the holders thereof to vote at any adjournment of such meeting, but
shall not be valid after the final adjournment thereof. No proxy shall be valid
after the expiration of eleven months from the date of its execution unless the
shareholder executing it shall have specified therein the length of time it is
to continue in force, which shall be for some limited period.

      Section 10. Voting of Shares. Except as otherwise provided in the
certificate of incorporation or these by-laws, each outstanding share entitled
to vote shall be entitled to one vote upon each matter submitted to a vote at a
meeting of shareholders.

      Shares standing in the name of another corporation may be voted by such
officer, agent or proxy as the by-laws of such corporation may prescribe, or in
the absence of such provision, as the Board of Directors of such corporation may
determine.

      Shares held by an administrator, executor, guardian or conservator may be
voted by him, either in person or by proxy, without a transfer of such shares
into his name. Shares standing in the name of a trustee may be voted by him,
either in person or by proxy, but no trustee shall be entitled to vote shares
held by him without a transfer of such shares into his name.

      Section 11. Informal Action by Shareholders. Any action required to be
taken at a meeting of the shareholders, or any other action which may be taken
at a meeting of the shareholders, may be taken without a meeting if a consent in
writing, setting forth the action so taken, shall be signed by all of the
shareholders entitled to vote with respect to the subject matter thereof.

      Section 12. Cumulative Voting. At all elections of directors of the
corporation, every shareholder entitled to vote at such election shall have the
right to vote, in person or by proxy, the number of shares owned by him for as
many persons as there are directors to be elected and for whose election he has
a right to vote, or to cumulate his votes by giving one candidate as many votes
as the number of such directors multiplied by the number of his shares shall
equal, or by distributing such votes on the same principle among any number of
candidates.

constitute the first Board of Directors of this corporation. Thereafter the
number of directors shall be determined and they shall be chosen by ballot
annually by the shareholders at their annual meeting or at any meeting held in
place thereof as provided by law. In the event that the corporation has less
than three shareholders the number of directors shall not be less than the
number of record holders of the corporation's shares. Each director shall serve
until the next annual meeting of the shareholders or until his successor is duly
elected and qualified. Directors shall be of full age and citizens of the United
States, but directors need not be residents of the State of Tennessee nor
shareholders of the corporation.

      Section 2. Powers of Directors. The Board of Directors shall have the
entire management of the business of the corporation. In the management and
control of the property, business and affairs of the corporation, the Board of
Directors is hereby vested with all the powers possessed by the corporation
itself, so far as this delegation of authority is not inconsistent with the laws
of the State of Tennessee,


                                     - 10 -
<PAGE>

with the certificate of incorporation of the corporation, or with these by-laws.
The Board of Directors shall have the power to determine what constitutes net
earnings, profits, and surplus, respectively, what amount shall be reserved for
working capital and to establish reserves for any other proper purpose, and what
amount shall be declared as dividends, and such determination by the Board of
Directors shall be final and conclusive. The Board of Directors shall have the
power to declare dividends for and on behalf of this corporation, which
dividends may include or consist of stock dividends.

      Section 3. Regular Meetings of the Board. Immediately after such annual
election the newly elected directors may meet at the same place for the purpose
of organization, the election of corporate officers and the transaction of other
business; if a quorum of the directors be then present no prior notice of such
meeting shall be required. Other regular meetings of the Board shall be held at
such times and places as the Board by resolution may determine and specify, and
if so determined no notice thereof need be given, provided that unless all the
directors are present at the meeting at which said resolution is passed, that
the first meeting held pursuant to said resolution shall not be held for at
least five days following the date on which the resolution is passed.

      Section 4. Special Meetings. Special meetings of the Board of Directors
may be held at any time or place whenever called by the President, or the
Vice-President or the Treasurer or the Secretary, or by written request of at
least two directors, notice thereof being given to each director by the
Secretary or other officer calling the meeting, or they may be held at any time
without formal notice provided all of the directors are present or those not
present shall at any time waive or have waived notice thereof.

      Section 5. Notice. Notice of any special meetings shall be given at least
five days previously thereto by written notice delivered personally or mailed to
each director at his business address, or by telegram. If mailed, such notice
shall be deemed to be delivered when deposited in the United States mail so
addressed, with postage thereon prepaid. If notice be given by telegram, such
notice shall be deemed to be delivered when the telegram is delivered to the
telegraph company.

      Section 6. Quorum. A majority of the members of the Board of Directors as
constituted for the time being shall constitute a quorum for the transaction of
business, but a lesser number may adjourn any meeting and the meeting may be
held as adjourned without further notice. When a quorum is


                                     - 12 -
<PAGE>

present at any meeting, a majority of the members present thereat shall decide
any question brought before such meeting, except as otherwise provided by law or
by these by-laws. The fact that a director has an interest in a matter to be
voted on by the meeting shall not prevent his being counted for purposes of a
quorum.

      Section 7. Vacancies. Any vacancy occurring in the Board of Directors,
including vacancies by virtue of removal for cause, may be filled by the vote of
a majority of the Directors, even though less than a quorum.

      Section 8. Compensation. By resolution of the Board of Directors, the
directors may be paid their expenses, if any, of attendance at each meeting of
the Board of Directors, and may be paid a fixed sum for attendance at each
meeting of the Board of Directors or a stated salary as a director. No such
payment shall preclude any director from serving the corporation in any other
capacity and receiving compensation therefor.

      Section 9. Removal. Any director may be removed without cause by a
majority vote of the shareholders. A director may be removed for cause by a
majority of the entire Board of Directors. Cause shall be defined as the


                                     - 13 -
<PAGE>

final conviction of a felony, declaration of unsound mind by court order,
adjudication of bankruptcy, nonacceptance of office or conduct prejudicial to
the interest of the corporation. Provided, however, that no director may be
removed when the votes cast against his removal would be sufficient to elect him
if voted cumulatively at an election at which the same total number of votes
were cast and the entire board of which he is a member were then being elected.

      Section 10. Committees. The majority of the Board of Directors may appoint
an executive committee or such other committees as it may deem advisable,
composed of two or more directors, and may delegate authority to such committees
as is not inconsistent with the Tennessee General Corporation Act. The members
of such committee shall serve at the pleasure of the Board of Directors.

      Section 11. Presumption of Assent. A director of the corporation who is
present at a meeting of the Board of Directors at which action on any corporate
matter is taken shall be presumed to have assented to the action taken unless
his dissent shall be entered in the minutes of the meeting or unless he shall
file his written dissent to such action with the person acting as the Secretary
of the meeting before the adjournment thereof or shall forward such dissent


                                     - 14 -
<PAGE>

by registered mail to the Secretary of the corporation immediately after the
adjournment of the meeting. Such right to dissent shall not apply to a director
who voted in favor of such action.

      Section 12. Informal Action by Directors. Any action required to be taken
at a meeting of the Board of Directors, or any other action which may be taken
at a meeting of the Board of Directors, may be taken without a meeting if a
consent in writing, setting forth the action so taken, shall be signed by all of
the directors entitled to vote with respect to the subject matter thereof.

the certificate of incorporation of this corporation, or any other corporation
laws of the State of Tennessee, a waiver thereof in writing signed by the person
or persons entitled to such notice, whether before or after the time stated
therein, shall be deemed equivalent thereto. Where the person or persons
entitled to such notice sign the minutes of any shareholder's or directors
meeting, which minutes contain the statement that said person or persons


                                     - 15 -

be. Each officer shall hold office until his successor shall have been duly
elected and shall have qualified or until his

death or until he shall resign or shall have been removed in the manner
hereinafter provided.

removed.
