                       St. Lucie Outdoor Advertising, Inc.

                              A Florida Corporation

                            Article I. - Shareholders

       1.1 Annual Meeting. A meeting of shareholders shall be held each year
for the election of directors and for the transaction of any other business that
may come before the meeting. The time and place of the meeting shall be
designated by the Board of Directors.

       1.2 Special Meeting. Special meetings of the shareholders, for any
purpose or purposes, shall be held when directed by the Board of Directors, or
at the request of the holders of not less than one tenth of all outstanding
shares of the corporation entitled to vote at the meeting.

       1.3 Place of Meeting. The Board of Directors may designate any place,
either within or without the State of Florida, as the place of meeting for any
annual or special meeting of the shareholders. If no designation is made, the
place of meeting shall be the principal office of the corporation [in the state
of Florida].

       1.4 Action Without a Meeting. Unless otherwise provided in the articles
of incorporation, action required or permitted to be taken at any meeting of the
shareholders may be taken without a meeting, without prior notice, and without a
vote if the action is taken by the holders of outstanding shares of each voting
group entitled to vote on it having not less than the minimum number of votes
with respect to each voting group that



   2
would be necessary to authorize or take such action at a meeting at which all
voting groups and shares entitled to vote were present and voted. In order to be
effective, the action must be evidenced by one or more written consents
describing the action taken, dated and signed by approving shareholders having
the requisite number of votes of each voting group entitled to vote, and
delivered to the corporation at its principal office in Florida or its principal
place of business, or to the corporate secretary or another office or agent of
the corporation having custody of the book in which proceedings of meetings of
shareholders are recorded. No written consent shall be effective to take
corporate action unless, within 60 days of the date of the earliest dated
consent delivered in the manner required by this section, written consents
signed by the number of holders required to take action are delivered to the
corporation.

       Any written consent may be revoked before the date that the corporation
receives the required number of consents to authorize the proposed action. No
revocation is effective unless in writing and until received by the corporation
at its principal office or its principal place of business, or received by the
corporate secretary or other office or agency of the corporation having custody
of the book in which proceedings of meetings of shareholders are recorded.

       Within ten days after obtaining authorization by written consent, notice
must be given to those shareholders who have not consented in writing or who are
not entitled to vote on the action. The notice shall fairly summarize the
material features of the


                                      BL2
   3
authorized action and, if the action is one for which dissenters' rights are
provided under the articles of incorporation or by law, the notice shall contain
a clear statement of the right of shareholders dissenting there from to be paid
the fair value of their shares upon compliance with applicable law.

       A consent signed as required by this section has the effect of a meeting
vote and may be described as such in any document.

       Whenever action is taken as provided in this section, the written consent
of the shareholders consenting or the written reports of inspectors appointed to
tabulate such consents shall be filed with the minutes of proceedings of
shareholders.

       1.5 Notice of Meeting. Except as provided in F.S. Chapter 607, the
Florida Business Corporation Act, written or printed notice stating the place,
day, and hour of the meeting and, in the case of a special meeting, the purpose
or purposes for which the meeting is called, shall be delivered not less than 10
nor more than 60 days before the date of the meeting, either personally or by
first-class mail, by, or at the direction of, the president or the secretary, or
the officer or other persons calling the meeting, to each shareholder of record
entitled to vote at the meeting. If the notice is mailed at least 30 days before
the date of the meeting, it may be effected by a class of United States mail
other than first-class. If mailed, the notice shall be effective when mailed, if
mailed, postage prepaid and correctly addressed to the shareholder's address
shown in the current record of shareholders of the corporation.


                                      BL3
   4
       When a meeting is adjourned to another time or place, it shall not be
necessary to give any notice of the adjourned meeting if the time and place to
which the meeting is adjourned are announced at the meeting at which the
adjournment is taken. At the adjourned meeting any business may be transacted
that might have been transacted on the original date of the meeting. If,
however, after the adjournment the Board of Directors fixes a new record date
for the adjourned meeting, a notice of the adjourned meeting shall be given as
provided in this section to each shareholder of record on the new record date
entitled to vote at such meeting.

       1.6 Waiver of Notice of Meeting. Whenever any notice is required to be
given to any shareholder, a waiver in writing signed by the person or persons
entitled to such notice, whether signed before, during, or after the time of the
meeting and delivered to the corporation for inclusion in the minutes or filing
with the corporate records, shall be equivalent to the giving of such notice.
Attendant of a person at a meeting shall constitute a waiver of (a) lack of or
defective notice of the meeting, unless the person objects at the beginning of
the meeting to the holding of the meeting or the transacting of any business at
the meeting or (b) lack of defective notice of a particular matter at a meeting
that is not within the purpose or purposes described in the meeting notice,
unless the person objects to considering the matter when it is presented.

       1.7 Fixing of Record Date. In order that the corporation may determine
the shareholders entitled to notice of, or to vote at, any meeting of
shareholders or any


                                      BL4
   5
adjournment thereof, or to express consent to corporate action in writing
without a meeting, or to demand a special meeting, the board of directors may
fix, in advance, a record date, not more than 70 days before the date of the
meeting or any other action. A determination of shareholders of record entitled
to notice of, or to vote at, a meeting of shareholders shall apply to any
adjournment of the meeting unless the board fixes a new record date, which it
must do if the meeting is adjourned to a date more than 120 days after the date
fixed for the original meeting.

       If no prior action is required by the board, the record date for
determining shareholders entitled to take action without a meeting is the date
the first signed written consent is delivered to the corporation under Section
1.4 of this Article.

       1.8 Voting Record. After fixing a record date for a meeting of
shareholders, the corporation shall prepare an alphabetical list of the names of
all its shareholders entitled to notice of the meeting, arranged by voting group
with the address of, and the number, class, and series, if any, of shares held
by, each shareholder. The shareholders' list must be available for inspection by
any shareholder for a period of ten days before the meeting or such shorter time
as exists between the record date and the meeting and continuing through the
meeting at the corporation's principal office, at a place identified in the
meeting notice in the city where the meeting will be held, or at the office of
the corporation's transfer agent or registrar. Any shareholder of the
corporation or the


                                      BL5
   6
shareholder's agent or attorney is entitled on written demand to inspect the
shareholders' list (subject to the requirements of F.S. 607.1602[3]) during
regular business hours and at the shareholder's expense, during the period it is
available for inspection.

       The corporation shall make the shareholders' list available at the
meeting of shareholder, and any shareholder or the shareholder's agent or
attorney is entitled to inspect the list at any time during the meeting or any
adjournment.

       1.9 Voting Per Share. Except as otherwise provided in the articles of
incorporation or by F.S. 607.0721, each shareholder is entitled to one vote for
each outstanding share held by him or her on each matter voted at a
shareholders' meeting.

       1.10 Voting of Shares. A shareholder may vote at any meeting of
shareholders of the corporation, either in person or by proxy.

       Shares standing the name of another corporation domestic or foreign, may
be voted by the officer, agent, or proxy designated by the by-laws of the
corporate shareholder, or in the absence of any applicable by-law, by a person
or persons designated by the board of directors of the corporate shareholder. In
the absence of any such designation or, in case of conflicting designation by
the corporate shareholder, the chairman of the board, the president, any vice
president, the secretary, and the treasurer of the corporate shareholder, in
that order, shall be presumed to be fully authorized to vote the shares.


                                      BL6
   7
       Shares held by an administrator, executor, guardian, personal
representative, or conservator may be voted by him or her, either in person or
by proxy, without a transfer of such shares into his or her name. Shares
standing in the name of a trustee may be voted by him or her, either in person
or by proxy, but no trustee shall be entitled to vote shares held by him or her
without a transfer of such shares into his or her name or the name of his or her
nominee.

       Shares held by or under the control of, a receiver, a trustee in
bankruptcy proceedings, or any assignee for the benefit of creditors may be
voted by such person without the transfer into his or her name.

       If shares stand of record in the names of two or more persons, whether
fiduciaries, members of a partnership, joint tenants, tenants in common, tenants
by the entirety, or otherwise, or if two or more persons have the same fiduciary
relationship respecting the same shares, unless the secretary of the corporation
is given notice to the contrary and furnished with a copy of the instrument or
order appointing them or creating the relationship wherein it is so provided,
then acts with respect to voting shall have the following effect: (a) if only
one votes, in person or by proxy, that act binds all; (b) if more than one vote,
in person or by proxy, one out of the majority so voting binds all; (c) if more
than one votes, in person or by proxy, but the vote is evenly split on any
particular matter, each faction is entitled to vote the share or shares in
question proportionally; or (d) if the instrument or order so filed shows that
any such tenancy is


                                      BL7
   8
held in unequal interest, a majority or a vote evenly split for purposes hereof
shall be a majority or a vote evenly split in interest. The principles of this
paragraph shall apply, insofar as possible, to execution of proxies, waivers,
consents, or objections and for the purpose of ascertaining the presence of a
quorum.

       1.11 Proxies. Any shareholder of the corporation, other person entitled
to vote on behalf of a shareholder pursuant to F.S. 607.0721, or
attorney-in-fact for such persons, may vote the shareholder's shares in person
or by proxy. Any shareholder may appoint a proxy to vote or otherwise act for
him or her by signing an appointment form, either personally or by an
attorney-in-fact. An executed telegram or cablegram appearing to have been
transmitted by such person, or a photographic, photostatic, or equivalent
reproduction of an appointment form, shall be deemed a sufficient appointment
form.

       An appointment of a proxy is effective when received by the secretary of
the corporation or such other officer or agent authorized to tabulate votes, and
shall be valid for up to 11 months, unless a longer period is expressly
provided in the appointment form.

       The death or incapacity of the shareholder appointing a proxy does not
affect the right of the corporation to accept the proxy's authority unless
notice of the death or incapacity is received by the secretary or other officer
or agent authorized to tabulate votes before the proxy exercises authority under
the appointment.


                                      BL8
   9
       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.

       1.12 Quorum. 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 provided in the articles of
incorporation or by law, a majority of the shares entitled to vote on the matter
by each voting group, represented in person or by proxy, shall constitute a
quorum at any meeting of shareholders, but in no event shall a quorum consist of
less than one third of the shares of each voting group entitled to vote. If less
than a majority of outstanding shares entitled to vote are represented at a
meeting, a majority of the shares so represented may adjourn the meeting from
time to time without further notice. After a quorum has been established at any
shareholders' meeting, the subsequent withdrawal of shareholders, so as to
reduce the number of shares entitled to vote at the meeting below the number
required for a quorum, shall not affect the validity of any action taken at the
meeting or any adjournment thereof.

       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.

       1.13 Manner of Action. If a quorum is present, action on a matter (other
than the election of directors) by a voting group is approved if the votes case
within the voting


                                      BL9
   10
group favoring the action exceed the votes case opposing the action, unless a
greater or lesser number of affirmative votes is required by the articles of
incorporation or by law.

       1.14 Voting for Directors. Unless otherwise provided in the articles of
incorporation, directors will be 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.

       1.15 Inspectors of Election. Before each shareholders' meeting, the
board of directors or president shall appoint one or more Inspectors of
Election. Upon appointment, each inspector shall take and sign an oath
faithfully to execute the duties of inspector at the meeting with strict
impartiality and to the best of his or her ability. Inspectors shall determine
the number of shares outstanding, the number of shares present at the meeting,
and whether a quorum is present. The inspectors shall receive votes and ballots
and determine all challenges and questions as to the right to vote. The
inspectors shall count and tabulate all votes and ballots and determine the
results. Inspectors shall perform other duties as are proper to conduct
elections of directors and votes on other matters with fairness to all
shareholders. Inspectors shall make a certificate of the results of elections of
directors and votes on other matters. No inspector shall be a candidate for
election as a director of the corporation.

and by law, all corporate powers shall be exercised by or under the authority

directors of the corporation shall consist of One persons. The number of
directors may at any time and from time to time be increased or decreased by
action of either the shareholders or the board of directors, but no decrease in
the number of directors shall have the effect of shortening the term of any
incumbent director. A director must be a natural person of at least 18 years of
age, but need not be a citizen of the United States of America, a resident of
the State of Florida, not a shareholder of the corporation. Each director shall
hold office until a successor has been elected and qualified or until an earlier
resignation, removal from office, or death.

       2.3 Regular Meeting. An annual regular meeting of the board of directors
shall be held without notice immediately after, and at the same place as, the

determined by the board of directors. The board may, at any time and from time
to time, provide by resolution the time and place, either within or without the
State of Florida, for the holding of the annual


                                     BL11
   12
regular meeting or additional regular meeting of the board without other notice
than the resolution.

       2.4 Special Meetings. Special meetings of the board of directors may be
called by the chairman of the board, the president, or any two directors.

       The person or persons authorized to call special meetings of the board
may designate any place, either within or without the State of Florida, as the
place for holding any special meeting of the board called by them. If no
designation is made, the place of the meeting shall be the principal office of
the corporation in Florida.

       Notice of any special meeting of the board may be given by any reasonable
means, oral or written, and at any reasonable time before the meeting. The
reasonableness of notice given in connection with any special meeting of the
board shall be determined in light of all pertinent circumstances. It shall be
presumed that notice of any special meeting given at least two days before the
meeting either orally (by telephone or in person), or by written notice
delivered personally or mailed to each director at his or her business or
residence address, is reasonable. If mailed, the notice of any special meeting
shall be deemed to be delivered on the second day after it is deposited in the
United States mail, so addressed, with postage prepaid. If notice is given by
telegram, it shall be deemed to be delivered when the telegram is delivered to
the telegraph company. Neither the business to be transacted at, nor the purpose
or purposes of, any special


                                      BL12
   13
meeting need to be specified in the notice or in any written waiver of notice of
the meeting.

       2.5 Waiver of Notice of Meeting. Notice of a meeting of the board of
directors need not be given to any director who signs a written waiver of notice
before, during, or after the meeting. Attendance of a director at a meeting
shall constitute a waiver of notice of the meeting and a waiver of any and all
objections to the place of the meeting, the time of the meeting, and the manner
in which it has been called or convened, except when a director states, at the
beginning of the meeting or promptly upon arrival at the meeting, any objection
to the transaction of business because the meeting is not lawfully called or
convened.

       2.6 Quorum. A majority of the number of directors fixed by, or in the
manner provided in, these by-laws shall constitute a quorum for the transaction
of business; provided however, that whenever, for any reason, a vacancy occurs
in the board of directors, a quorum shall consist of a majority of the remaining
directors until the vacancy has been filled.

       2.7 Manner of Action. The act of a majority of the directors present at a
meeting at which a quorum is present when the vote is taken shall be the act of
the board of directors.

       2.8 Presumption of Assent. A director of the corporation who is present
at a meeting of the board of directors or a committee of the board when
corporate action is taken shall be presumed to have assented to the action
taken, unless he or she objects at the beginning of the meeting, or promptly
upon arrival, to holding the meeting or 


                                      BL13
   14
transacting specific business at the meeting, or he or she votes against or
abstains from the action taken.

       2.9 Action Without a Meeting. Any action required or permitted to be
taken at a meeting of the board of directors or a committee of it may be taken
without a meeting if a consent in writing, stating the action so taken, is
signed by all the directors. Action taken under this section is effective when
the last director signs the consent, unless the consent specifies a different
effective date. A consent signed under this section shall have the effect of a
meeting vote and may be described as such in any document.

       2.10 Meetings by Means of Conference Telephone Call or Similar Electronic
Equipment. Members of the board of directors may participate in a meeting of the
board by means of a conference telephone call or similar communications
equipment if all persons participating in the meeting can hear each other at the
same time. Participation by such means constitutes presence in person at a
meeting.

       2.11 Resignation. Any director may resign at any time by giving written
notice to the corporation, the board of directors, or its chairman. The
resignation of any director shall taken effect when the notice is delivered
unless the notice specifies a later effective date, in which the event the board
may fill the pending vacancy before the effective date if they provide that the
successor does not take office until the effective date.

   15
       2.12 Removal. Any director, or the entire board of directors, may be
removed at any time, with or without cause, by action of the shareholder, unless
the articles of incorporation provide that directors may be removed only for
cause. If a director was elected by a voting group of shareholders, only the
shareholders of that voting group may participate in the vote to remove that
director. The notice of the meeting at which a vote is taken to remove a
director must state that the purpose or one of the purposes of the meeting is
the removal of the director or directors.

       2.13 Vacancies. Any vacancy in the board of directors, including any
vacancy created by reason of an increase in the number of directors, may be
filled by the affirmative vote of a majority of the remaining directors though
less than a quorum of the board of directors, or by the shareholders.

       2.14 Compensation. Each director may be paid the expenses, if any, of
attendance at each meeting of the board of directors, and may be paid a stated
salary as a director of a fixed sum for attendance at each meeting of the board
of directors or both, as may from time to time be determined by action of the
board of directors. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefore.

                Article 3 - Committees of the Board of Directors

       The board of directors, by resolution adopted by a majority of the full
board, may designate from among its members an executive committee and one or
