prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made); and (2) if the notice relates to action to be considered at any other meeting, a shareholder’s notice shall be delivered to the secretary at the principal business office of the corporation not later than the tenth (10th) day following the day on which public announcement of the date of such meeting is first made. In no event shall the public announcement of an adjournment or postponement of a meeting commence a new time period (or extend any time period) for the giving of a shareholder’s notice as described above.

Such shareholder’s notice shall set forth: (A) as to each person whom the shareholder proposes to nominate for election as a director (i) all information relating to such person that is required to be disclosed in solicitations of proxies for the election of directors in an election contest, or is otherwise required, in each case pursuant to and in accordance with Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations promulgated thereunder, and (ii) such person’s written consent to being named as a nominee and serve as a director if elected; and (B) as to the shareholder giving the notice and the beneficial owner, if any, on whose behalf the nomination is made (i) the name and address of such shareholder, as they appear on the corporation’s books, and of such beneficial owner, (ii) the class or series and number of shares of stock of the corporation owned of record by such shareholder and such beneficial owner, (iii) a description of any agreement, arrangement or understanding with respect to the nomination between or among such shareholder or beneficial owner or any of their respective affiliates or associates, on the one hand, and any other person or persons acting in concert with any of the foregoing, on the other hand, (iv) a description of any agreement, arrangement or understanding (including in respect of any derivative or short positions, profit interests, options, warrants, convertible securities, stock appreciation or similar rights, hedging transactions, or borrowed, or loaned shares) that has been entered into as of the date of the shareholder’s notice by, or on behalf of, such shareholder or such beneficial owner, whether or not any such position, interest, security, instrument, right, transaction or shares shall be subject to settlement in an underlying class or series of stock of the corporation, the effect or intent of which is to mitigate loss to, manage the risk or benefit of share price changes for, or increase or decrease the voting power of, such shareholder or such beneficial owner with respect to shares of stock of the corporation, or relates to the acquisition or disposition of any shares of stock of the corporation, (v) a representation that the shareholder is a holder of record of stock of the corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such nomination, (vi) a representation whether the shareholder or the beneficial owner intends or is part of a group which intends (a) to deliver a proxy statement or form of proxy to holders of at least the percentage of the corporation’s outstanding stock required to elect the nominee or (b) otherwise to solicit proxies from shareholders in support of such nomination and (vii) any other information relating to such shareholder and beneficial owner that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for the election of directors in an election contest pursuant to and in accordance with Section 14(a) of the Exchange Act and the rules and regulations promulgated thereunder. The corporation may require any proposed nominee to furnish such other information as the corporation may reasonably require.

Notwithstanding anything in this Section to the contrary, in the event the number of directors to be elected to the board of directors of the corporation is to be increased effective at the annual meeting and there is no public announcement by the corporation naming nominees for all the new positions to be created by such increase or specifying the size of the increased board of directors at least one hundred (100) days prior to the first anniversary of the preceding year’s annual meeting, a shareholder’s notice required by this Section shall also be considered timely, but only with respect to nominees for any new position created by such increase, if it shall be delivered to the secretary at the principal business office of the corporation not later than the close of business on the tenth (10th) day following the day on which such public announcement is first made by the corporation.

Notwithstanding the foregoing, in order to include information with respect to a shareholder proposal in the proxy statement and form of proxy for a shareholder’s meeting, the shareholder must provide notice as required by, and otherwise comply with the requirements of, the Exchange Act and the regulations promulgated thereunder.

The chairman of the meeting may refuse to acknowledge any nomination not made in compliance with the foregoing.

To be timely, (1) if the notice relates to action to be considered at an annual meeting, a shareholder’s notice shall be delivered to the secretary at the principal business office of the corporation not later than the close of business on the ninetieth (90th) day, nor earlier than the close of business on the one hundred twentieth (120th) day, prior to the first anniversary of the preceding year’s annual meeting (provided, however, that in the event that the date of the annual meeting is more than thirty (30) days before or more than seventy (70) days after such anniversary date, notice by the shareholder must be so delivered not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90th) day prior to such annual meeting or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made); and (2) if the notice relates to action to be considered at any other meeting, a shareholder’s notice shall be delivered to the secretary at the principal business office of the corporation not later than the tenth (10th) day following the day on which public announcement of the date of such meeting is first made. In no event shall the public announcement of an adjournment or postponement of a meeting commence a new time period (or extend any time period) for the giving of a shareholder’s notice as described above.

The corporation may require any proposed nominee to furnish such other information as the corporation may reasonably require.

When authorizing such issue of a new certificate or certificates, 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 certificates, 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.

Shares shall be transferable only on the corporation’s books, upon surrender of the certificate for the shares, properly endorsed, if such shares are certificated.  The Board may require satisfactory surety before issuing a new certificate to replace a certificate claimed to have been lost or destroyed.

Section 6. Registered Shareholders. The corporation shall be entitled to treat the person in whose name shares are registered on its books as the owner of such shares for all purposes.
