If mailed, such notice shall be deemed to be delivered when deposited in the United States mail, addressed to the stockholder at his address as it appears on the stock transfer books or records of the Corporation as of the record date prescribed in Section 6, with postage thereon prepaid. If a stockholder is present at a meeting, or in writing waives notice thereof before or after the meeting, notice of the meeting to such stockholder shall be unnecessary. When any

stockholders’ meeting, either annual or special, is adjourned for thirty days or more, notice of the adjourned meeting shall be given as in the case of an original meeting. It shall not be necessary to give any notice of the time and place of any meeting adjourned for less than thirty days or of the business to be transacted at such adjourned meeting, other than an announcement at the meeting at which such adjournment is taken.

SECTION 6. Fixing of Record Date. For the purpose of determining stockholders entitled to notice of or to vote at any meeting of stockholders, or any adjournment thereof, or stockholders entitled to receive payment of any dividend, or in order to make a determination of stockholders for any other proper purpose, the board of directors shall fix in advance a date as the record date for any such determination of stockholders. Such date in any case shall be not more than sixty days, and in case of a meeting of stockholders not less than ten days, prior to the date on which the particular action requiring such determination of stockholders, is to be taken. When a determination of stockholders entitled to vote at any meeting of stockholders has been made as provided in this section, such determination shall apply to any adjournment thereof.

SECTION 7. Voting Lists. The officer or agent having charge of the stock transfer books for shares of the Corporation shall make, at least ten days before each meeting of stockholders, a complete record of the stockholders entitled to vote at such meeting or any adjournment thereof, with the address of and the number of shares held by each. The record, for a period of ten days before such meeting, shall be kept on file at the principal office of the Corporation, whether within or outside the State of Florida, and shall be subject to inspection by any stockholder for any purpose germane to the meeting at any time during usual business hours. Such record shall also be produced and kept open at the time and place of the meeting and shall be subject to the inspection of any stockholder for any purpose germane to the meeting during the whole time of the meeting. The original stock transfer books shall be prima facie evidence as to who are the stockholders entitled to examine such record or transfer books or to vote at any meeting of stockholders.

SECTION 8. Quorum. One-third of the outstanding shares of the Corporation entitled to vote, represented in person or by proxy, shall constitute a quorum at a meeting of stockholders. If less than one-third of the outstanding shares are represented at a meeting, a majority of the shares so represented may adjourn the meeting from time to time without further notice. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally notified. The stockholders present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

SECTION 9. Proxies. At all meetings of stockholders, a stockholder may vote by proxy executed in writing by the stockholder or by his duly authorized attorney in fact. Proxies solicited on behalf of the management shall be voted as directed by the stockholder or, in the absence of such direction, as determined by a majority of the board of directors. No proxy shall be valid after eleven months from the date of its execution unless otherwise provided in the proxy.

SECTION 10. Voting. At each election for directors every stockholder entitled to vote at such election shall be entitled to one vote for each share of stock held. Unless otherwise provided

2

by the Certificate of Incorporation, by statute, or by these Bylaws, a majority of those votes cast by stockholders at a lawful meeting shall be sufficient to pass on a transaction or matter, except in the election of directors, which election shall be determined by a plurality of the votes of the shares present in person or by proxy at the meeting and entitled to vote on the election of directors.

SECTION 11. Voting of Shares in the Name of Two or More Persons. When ownership of stock stands in the name of two or more persons, in the absence of written directions to the Corporation to the contrary, at any meeting of the stockholders of the Corporation any one or more of such stockholders may cast, in person or by proxy, all votes to which such ownership is entitled. In the event an attempt is made to cast conflicting votes, in person or by proxy, by the several persons in whose name shares of stock stand, the vote or votes to which these persons are entitled shall be cast as directed by a majority of those holding such stock and present in person or by proxy at such meeting, but no votes shall be cast for such stock if a majority cannot agree.

SECTION 12. Voting of Shares by Certain Holders. Shares standing in the name of another corporation may be voted by any officer, agent or proxy as the bylaws 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. Shares standing in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without the transfer thereof into his name if authority to do so is contained in an appropriate order of the court or other public authority by which such receiver was appointed.

A stockholder whose shares are pledged shall be entitled to vote such shares until the shares have been transferred into the name of the pledgee and thereafter the pledgee shall be entitled to vote the shares so transferred.

Neither treasury shares of its own stock held by the Corporation, nor shares held by another corporation, if a majority of the shares entitled to vote for the election of directors of such other corporation are held by the Corporation, shall be voted at any meeting or counted in determining the total number of outstanding shares at any given time for purposes of any meeting.

SECTION 13. Inspectors of Election. In advance of any meeting of stockholders, the chairman of the board or the board of directors may appoint any persons, other than nominees for office, as inspectors of election to act at such meeting or any adjournment thereof. The number of inspectors shall be either one or three. If the board of directors so appoints either one or three inspectors, that appointment shall not be altered at the meeting. If inspectors of election are not so appointed, the chairman of the board may make such appointment at the meeting. In case any person appointed as inspector fails to appear or fails or refuses to act, the vacancy may be filled by appointment in advance of the meeting or at the meeting by the chairman of the board or the president

Unless otherwise prescribed by applicable law, the duties of such inspectors shall include: determining the number of shares of stock and the voting power of each share, the

3

shares of stock represented at the meeting, the existence of a quorum, the authenticity, validity and effect of proxies; receiving votes, ballots or consents; hearing and determining all challenges and questions in any way arising in connection with the right to vote; counting and tabulating all votes or consents; determining the result; and such acts as may be proper to conduct the election or vote with fairness to all stockholders.

SECTION 14. Nominating Committee. The board of directors or a committee appointed by the board of directors shall act as a nominating committee for selecting the management nominees for election as directors. Except in the case of a nominee substituted as a result of the death or other incapacity of a management nominee, the nominating committee shall deliver written nominations to the secretary at least twenty days prior to the date of the annual meeting. Provided such committee makes such nominations, no nominations for directors except those made by the nominating committee shall be voted upon at the annual meeting unless other nominations by stockholders are made in writing and delivered to the secretary of the Corporation in accordance with the provisions of the Corporation’s Certificate of Incorporation.

SECTION 15. New Business. Any new business to be taken up at the annual meeting shall be stated in writing and filed with the secretary of the Corporation in accordance with the provisions of the Corporation’s Certificate of Incorporation. 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 provided in the Corporation’s Certificate of Incorporation.

The board of directors may also elect or authorize the appointment of such other officers as the business of the Corporation may require.

The shares of the Corporation shall be represented by certificates, provided that the board of directors may provide by resolution or resolutions that some or all of any or all classes or series of the Corporation’s stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the Corporation. Every holder of stock represented by certificates shall be entitled to have a certificate signed by, or in the name of the Corporation by, the chairman of the board of directors, or the president or any vice president, and by the treasurer or an assistant treasurer, or the secretary or an assistant secretary of the Corporation, representing the number of shares registered in certificate form, and may be sealed with the seal of the Corporation or a facsimile thereof. Any or all of the signatures upon a certificate may be facsimiles if the certificate is countersigned by a transfer agent, or registered by a registrar, other than the Corporation itself or an employee of the Corporation. If any officer, transfer agent, or registrar who has signed or whose facsimile signature has been placed upon such certificate shall have ceased to be such officer, transfer agent, or registrar before the certificate is issued, it may be issued by the Corporation with the same effect as if such person were such officer, transfer agent, or registrar at the date of its issue.

SECTION 2. Form of Share Certificates. All certificates representing shares issued by the Corporation shall set forth upon the face or back that the Corporation will furnish to any stockholder upon request and without charge a full statement of the designations, preferences, limitations, and relative rights of the shares of each class authorized to be issued, the variations in the relative rights and preferences between the shares of each such series so far as the same have been fixed and determined, and the authority of the board of directors to fix and determine the relative rights and preferences of subsequent series.

Each certificate representing shares shall state upon the face thereof: That the Corporation is incorporated under the laws of the State of Delaware; the name of the person to whom issued; the number and class of shares, the designation of the series, if any, which such certificate represents; the par value of each share represented by such certificate, or a statement that the shares are without par value. Other matters in regard to the form of the certificates shall be determined by the board of directors.

SECTION 3. Payment for Shares. No certificate shall be issued for any share until such share is fully paid.

SECTION 4. Form of Payment for Shares. The consideration for the issuance of shares shall be paid in accordance with the provisions of the Corporation’s Certificate of Incorporation.

Authority for such transfer shall be given only by the holder of record thereof or by such person’s legal representative, who shall furnish proper evidence of such authority, or by such person’s attorney thereunto authorized by power of attorney duly executed and filed with the Corporation. If such stock is certificated, such transfer shall be

9

made only on surrender for cancellation of the certificate for such shares. The person in whose name shares of capital stock stand on the books of the Corporation shall be deemed by the Corporation to be the owner thereof for all purposes.

SECTION 6. Lost Certificates. The board of directors may direct a new certificate to be issued in place of any certificate theretofore issued by the Corporation alleged to have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen, or destroyed. When authorizing such issue of a new certificate, the board of directors may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen, or destroyed certificate, or his legal representative, to give the Corporation a bond in such sum as it may direct as indemnity against any claim that may be made against the Corporation with respect to the certificate alleged to have been lost, stolen, or destroyed.
