     Section 2. Special Meeting. - Special meetings of the shareholders, for any
purpose other than the election of Directors, may be called by the Chief

(including delivery to shareholder/employees by inter-company memorandum), or by
telegraph, teletype, other form of electronic communication or by mail, , to
each shareholder of record entitled to vote at such meeting. If mailed, such
notice shall be deemed to have been given when deposited in the United States
mail, addressed to the shareholder at his address as it appears on the stock
transfer books of the Corporation, with postage thereon prepaid. Notice may be
waived in writing, signed by the shareholder entitled to such notice, and shall
be delivered to the Corporation for inclusion in the minutes or filing with the

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 sixty (60) nor less than
ten (10) days prior to the date of the meeting or action requiring a
determination of the shareholders. 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 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 4, such
determination shall apply to any adjournment not exceeding 120 days from the
date fixed for the original meeting.

special meeting of shareholders shall be transacted unless notice thereof is
given as required by the provisions of Section 3 hereof. If a quorum is present,
the affirmative vote of the majority of the shares represented at the meeting
and entitled to vote on the subject matter shall be the act of the shareholders.

     Section 6. Proxies. - A shareholder may vote either in person or by proxy
executed in writing by the shareholder or by his duly authorized
attorney-in-fact. The proxy shall be voted only for the meeting specified in
said proxy and in no event shall a proxy be valid






                                                                               4

provided in the proxy. A proxy is revocable at the pleasure of the shareholder
executing it and is revocable by the transfer of shares by the shareholder
executing it.

     Section 7. Voting of Shares. - Each outstanding share, regardless of class,
shall be entitled to one vote on each matter submitted to a vote at a meeting of
shareholders, except to the extent that the voting rights of the shares are
limited or denied by Statute, by the Articles of Incorporation of the
Corporation or any amendments thereto, or by the certificate representing such
shares.

     Section 8. Action Without Meeting. - Any action required or permitted to be
taken at any meeting of the shareholders may be taken without a meeting, without
notice, and without a vote, if the action is taken by the holders of the
outstanding stock of each voting group entitled to vote thereon having not less
than the minimum number of votes with respect to each voting group that would be
necessary to authorize or to take the action at a meeting at which all voting
groups and shares entitled to vote thereon were present and voted. In order to
be effective the action of the shareholders must be evidenced by one or more
written consents describing the action taken, dated and signed by the
shareholders taking the action, and the written consents must be delivered to
the corporate secretary of the Corporation, within 60 days of the earliest
consent, at the Corporation's principal place of business in the State of

transmission, telegram, telegraph, teletype, telephone or other form of

special meeting of the Board of Directors need not be specified in the notice or
waiver of notice of such meeting.

a majority of the stock issued and outstanding and





                                                                              14

                                   -----------

                                EMERGENCY BY-LAWS
                                -----------------

     Section 1. The Emergency By-Laws provided in this ARTICLE XII shall be
operative during any emergency in the conduct of the business of the Corporation
resulting from an attack on the United States or any nuclear or atomic disaster
or during the existence of any catastrophe or other similar emergency condition,
as a result of which a quorum of the Board of Directors or a standing committee
thereof cannot readily be convened for action, notwithstanding any different
provision in these By-Laws or in the Articles of Incorporation of the
Corporation or any amendments thereto or in the Florida Statutes. To the extent
not inconsistent with the provisions of this ARTICLE XII, the By-Laws provided
in all other Articles shall remain in effect during such emergency and upon its
termination the Emergency By-Laws shall cease to be operative.

     During any such emergency:

     (a) A meeting of the Board of Directors may be called by any officer or
Director of the Corporation. Notice of the time and price of the meeting shall
be given by the person calling the meeting to such members of the Board of
Directors as it may be feasible to reach by any available means of
communication. Such notice shall be given at such time in advance of the meeting
as circumstances permit in the judgment of the person calling the meeting.





                                                                              15

     (b) At any such meeting of the Board of Directors, a quorum shall consist
of such number of Directors as are present at such meeting.

     (c) The Board of Directors, either before or during any such emergency, may
provide, and from time to time modify, lines of succession in the event that
during such an emergency any or all officers or agents of the Corporation shall
for any reason be rendered incapable of discharging their duties.

     (d) The Board of Directors, either before or during any such emergency,
may, effective in the emergency, change the head office or designate several
alternative head offices or regional offices, or authorize the officers so to
do.

     Section 2. No officer, Director, or employee acting in accordance with
these Emergency By-Laws shall be liable except for willful misconduct.

     Section 3. These Emergency By-Laws shall be subject to repeal or change by
further action of the Board of Directors or by action of the shareholders, but
no such repeal or change shall modify the provisions of the next preceding
paragraph with regard to action taken prior to the time of such repeal or
change. Any amendment of these Emergency By-Laws may make any further or
different provision that may be practical and necessary for the circumstances of
the emergency.

                                  ARTICLE XIII
                                  ------------

                                  MISCELLANEOUS
                                  -------------

     In the event the Board of Directors shall consist of only one Director, or
in the event there shall be only one shareholder of the Corporation, then all
references to more than one Director or shareholder or a majority of Directors
or shareholders shall be inapplicable, such references in such events being
deemed to refer to the sole Director or sole shareholder. In the






                                                                              16

event there shall be only one shareholder who shall be the sole Director of the
Corporation, then upon the death of such shareholder, the personal
representatives of the estate of such deceased shareholder shall elect a
successor Director.

     In the event the Board of Directors shall consist of only two Directors,
then all references in these By-Laws to a majority of the Directors shall be
inapplicable.
