Section 2. Annual Meeting.

An annual meeting of stockholders for the election of directors and the transaction of such other business as may be properly brought before such meeting shall be held on a date no more than 12 months following the last date of the Corporation’s fiscal year. Any annual meeting of stockholders may be adjourned from time to time until the business to be transacted at such meeting is completed.

Section 3. Special Meetings.

Special meetings of stockholders can be called only as provided in the Certificate of Incorporation. Each such meeting shall be called by giving notice to that effect to the Secretary not more than sixty-five (65) days and not less than fifteen (15) days before the date of such meeting. Such notice shall state the place, date, hour and purpose or purposes of such meeting. Any special meeting may be adjourned in accordance with Section 5(c) of this Article I from time to time until the business to be transacted at such meeting is completed.

Section 4. Record Date.

(a) In order to determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing such record date is adopted by the Board and which record date shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be the close of business on the day next preceding the day on which notice of such meeting


is given or, if such notice is waived by all of the stockholders, the close of business on the day next preceding the day on which such meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for such adjourned meeting.

(b) In order to determine the stockholders entitled to consent to action in writing without a meeting, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing such record date is adopted by the Board and which record date shall not be more than ten (10) days after the date upon which the resolution fixing such record date is adopted by the Board. If no record date is fixed by the Board, the record date for determining stockholders entitled to consent to action in writing without a meeting, when no prior action by the Board is required by the General Corporation Law of the State of Delaware, as then in effect (the “Law”), shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation at its registered office in the State of Delaware, its principal place of business or an officer or agent of the Corporation having custody of the books in which proceedings of meeting of stockholders are recorded. Delivery made to the Corporation at its registered office shall be made by personal delivery or by certified or registered mail, return receipt requested. If no record date has been fixed by the Board and prior action by the Board is required by the Law, the record date for determining stockholders entitled to consent to action in writing without a meeting shall be the close of business on the day on which the Board adopts the resolution taking such prior action.

(c) In order to determine the stockholders (i) entitled to receive payment of any dividend or other distribution or allotment of any rights or to exercise any rights in respect of any change, conversion or exchange of shares of capital stock of the Corporation or (ii) for the purpose of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing such record date is adopted and which record date shall be not more than sixty (60) days prior to such action. If no record date is fixed, the record date for determining stockholders therefor shall be at the close of business on the day on which the Board adopts the resolution relating to such action.

Section 5. Notice of Meetings; Waiver.

(a) Each notice of each meeting of stockholders shall state the place, date and hour of such meeting and, unless it is an annual meeting of stockholders, shall indicate that it is being sent by or at the direction of the person or persons calling such meeting and state the purpose or purposes for which such meeting is being called. If at any meeting of stockholders action is proposed to be taken which would, if taken, give stockholders fulfilling the requirements of Section 262 of the Law the right to receive payment for their shares of capital stock of the Corporation, the notice of such meeting shall include a statement of such proposed action and such right. Not less than ten (10) nor more than sixty (60) days before the date of such meeting, the Secretary shall give or cause to be given a copy of the notice of such meeting, either by personal delivery or by mail, to each person entitled to notice of such meeting. If mailed, such notice shall be deemed to have been given to a stockholder when it is deposited in the United States mail, postage prepaid, directed to the stockholder at his address as it appears on the stock records of the Corporation or, if he shall have filed with the Secretary a written request that notices to him be mailed to some other address, then directed to him at such other address.


(b) A written waiver of notice of a meeting of stockholders signed by a stockholder entitled to notice of such meeting, before or after such meeting, shall be deemed to be equivalent to the giving of proper notice to such stockholder of such meeting. Attendance of a stockholder at a meeting of stockholders shall constitute a waiver of notice of such meeting, except when such stockholder attends such meeting for the express purpose of objecting, at the commencement of such meeting, to the transaction of any business at such meeting because such meeting was not lawfully called or convened. Neither the business to be transacted at nor the purpose of a meeting of stockholders is required to be specified in any written waiver of notice of such meeting.

(c) When a meeting of stockholders 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 such meeting is adjourned are announced at such meeting. Any business may be transacted at such adjourned meeting which might have been transacted at such meeting. If the adjournment is for more than thirty (30) days or if, after such adjournment, the Board fixes a new record date for such adjourned meeting, a notice of such adjourned meeting shall be given to each person entitled to notice of such adjourned meeting.

Section 6. List of Stockholders.

The Secretary shall prepare, at least ten (10) days prior to each meeting of stockholders, a complete list of the stockholders entitled to vote at such meeting, arranged in alphabetical order and showing the address of each such stockholder and the number of shares held of record by each such stockholder. Such list shall be open for inspection by any stockholder, for purposes germane to such meeting, during ordinary business hours, for the ten (10) days prior to such meeting, either at a place in the city where such meeting is to be held, which place shall be specified in the notice of such meeting, or, if not so specified, at the place where such meeting is to be held. Such list shall also be produced and kept open at such meeting during the whole time thereof and may be inspected by any stockholder who is present thereat. The stock records of the Corporation shall be conclusive evidence as to who are the stockholders entitled to examine such stock records, the list described in this Section 6 or the books of the Corporation or to vote at any meeting of stockholders.

Section 7. Quorum; Manner of Acting.

(a) Except as otherwise required by the Law or the Certificate of Incorporation or as provided with respect to meetings consisting solely of holders of shares of Preferred Stock in the resolution or resolutions providing for the issuance of such shares, the presence, at the commencement of such meeting, in person or by proxy of holders of a majority of the issued and outstanding shares of capital stock of the Corporation entitled to vote at a meeting of stockholders shall be required in order to constitute a quorum for the transaction of business thereat.


(b) If a quorum shall not be present at the commencement of any meeting of stockholders, holders of a majority of the issued and outstanding shares of capital stock of the Corporation present in person or by proxy and entitled to vote at such meeting may adjourn such meeting to another time and place.

(c) Except as otherwise required by the Law or the Certificate of Incorporation and as otherwise provided in these By-Laws with respect to the election of directors and except as otherwise provided with respect to meetings consisting solely of holders of shares of Preferred Stock in the resolution or resolutions providing for the issuance of such shares, a matter submitted to a vote at a meeting of stockholders shall have been approved only if a quorum was present at the commencement of such meeting and the holders of a majority of the issued and outstanding shares of the capital stock of the Corporation present in person or by proxy at such meeting and entitled to vote on such matter shall have voted to approve such matter.

(d) Every stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for him by proxy. Such authorization must be granted by a means expressly permitted by the Law. No proxy shall be voted or acted upon after three (3) years from its date unless such proxy provides that it may be voted or acted upon for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A stockholder may revoke any proxy which is not irrevocable by attending the relevant meeting of stockholders and voting or acting in person, by filing with the Secretary a written instrument revoking such proxy or by filing with the Secretary another duly executed proxy bearing a later date.

Section 8. Business Transacted.

(a) No business shall be transacted at any meeting of stockholders unless it shall have been brought in accordance with this Section 8(a) of this Article I. Business may be brought (i) before a special meeting of stockholders only by the person or persons calling such meeting as permitted by the Certificate of Incorporation or (ii) before an annual meeting of stockholders only by or at the direction of the Board or any other person or persons who could call a special meeting of stockholders as permitted by the Certificate of Incorporation or by a stockholder who is entitled to vote thereon at such annual meeting and who complies with the procedures set forth in this Section 8. For business to be properly brought before an annual meeting of stockholders by a stockholder, such stockholder must have given timely notice of his intention to do so in writing to the Secretary. To be timely, such notice must be delivered or mailed to, and received at, the principal executive office of the Corporation not less than ninety (90) days prior to the date of such meeting; provided, however, that if less than ninety (90) days’ notice or prior public disclosure of the date of such meeting is given to stockholders or made, such notice must be so delivered or mailed, and received, not later than the close of business on the tenth (10th) day following the day on which notice or public disclosure of the date of such meeting is given or made.

The chairman of such meeting shall determine whether any business to be brought before such meeting will be properly so brought in accordance with this Section 8(a) of this Article I and, if he should determine that such business will not be properly so brought, he shall so declare at such meeting and such business shall not be transacted at such meeting.

For nominations to be properly made at a meeting by a stockholder, such stockholder must have given timely notice of his intention to do so in writing to the Secretary. To be timely, such notice must be delivered or mailed to, and received at, the principal executive office of the Corporation not less than ninety (90) days prior to the date of such meeting; provided, however, that if less than ninety (90) days’ notice or prior public disclosure of the date of such meeting is given to stockholders or made, such notice must be so delivered or mailed, and received, not later than the close of business on the tenth (10th) day following the day on which notice or public disclosure of the date of such meeting is given or made.

This Section shall not limit the right of the Corporation or any of its subsidiaries to vote any shares of capital stock of the Corporation held by the Corporation or such subsidiary in a fiduciary capacity.

(e) To the extent (but only to the extent) expressly provided in the Certificate of Incorporation, action required or permitted to be taken at a meeting of stockholders may be taken without a meeting, without any prior notice and without a vote thereon, if stockholders having not less than the minimum number of votes that would be necessary to take such action at a meeting at which all stockholders entitled to vote thereon were present and voting, consent in writing to such action and such writing or writings are filed with the minutes of proceedings of the stockholders. Prompt written notice of the taking of such action shall be given by the Secretary to all stockholders who have not consented in writing to such action.

ARTICLE V - INDEMNIFICATION

Section 1. Indemnification.

(a) Each person who is or was made a party or is threatened to be made a party to, or is or was involved in, any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”), by reason of the fact that he, or a person of whom he is the legal representative, is or was a director, officer, employee or, pursuant to a resolution or resolutions adopted by the affirmative vote of a majority of the Board, agent of the Corporation or a subsidiary of the Corporation or is or was serving at the request of the Corporation as a director, officer, partner, member, employee, agent or trustee of another


corporation (other than a subsidiary of the Corporation) or of a partnership, joint venture, trust or other enterprise, including an employee benefit plan, whether the basis of such proceeding is alleged action in an official capacity as an officer or director or in any other capacity while so serving, shall be indemnified by the Corporation for and held harmless by the Corporation from and against, to the fullest extent authorized by the Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader or greater rights to indemnification than the Law prior to such amendment permitted the Corporation to provide), all expenses, liabilities and losses (including attorneys’ fees, judgments, fines, excise taxes, penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith; provided, however, that except as provided herein with respect to proceedings seeking to enforce rights to indemnification, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board. Such right to indemnification shall continue as to a person who has ceased to be such an officer, director, partner, member, employee, agent or trustee and shall inure to the benefit of his or her heirs, executors and administrators. Such right to indemnification shall be a contract right and shall include the right of a director, officer, partner, member, employee, agent or trustee to be paid the expenses (including costs and attorneys’ fees and disbursements) incurred in defending a proceeding in advance of its final disposition to the fullest extent authorized by the Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader or greater rights to indemnification than the Law prior to such amendment permitted the Corporation to provide); provided, however, that, if the Law requires, the payment of such expenses incurred by a director or officer of the Corporation in his capacity as a director or officer of the Corporation (and not in any other capacity in which service was or is rendered by such person while a director or officer of the Corporation, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Article or otherwise. Such right to indemnification and to the payment of expenses may be granted to any other employee or agent of the Corporation or its subsidiaries if, and to the extent, authorized by the Board.

(b) If a claim under this Article is not paid in full by the Corporation within thirty (30) days after a written demand therefor has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall also be entitled to be paid the expense of prosecuting such suit. It shall be a defense to any such suit (other than a suit brought to enforce a claim for expenses incurred in defending a proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the Law for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including the Board, independent legal counsel to the Corporation or the stockholders) to have made a determination prior to the commencement of such suit that indemnification of the claimant is proper in the circumstances because he or she has met the


applicable standard of conduct set forth in the Law nor an actual determination by the Corporation (including the Board, independent legal counsel to the Corporation or the stockholders) that the claimant has not met such applicable standard of conduct shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Section 2. Indemnification Not Exclusive.

The indemnification of or the payment of expenses for any person under this Article, or the right of any person to indemnification or payment of expenses under this Article, shall not limit or restrict in any way the power of the Corporation to indemnify or pay expenses for such person in any other manner permitted by law or be deemed exclusive of, or invalidate, any other right which such person may have or acquire under any law, agreement, vote of stockholders or disinterested directors, or otherwise. The Corporation has the right to enter into indemnification contracts or otherwise arrange for indemnification of persons under this Article that may be broader than the indemnifications provided for herein.

Section 3. Successors.

The right of any person to indemnification and payment of expenses under this Article shall continue as to a person after such person shall have ceased to be such an officer, director, partner, member, employee, agent or trustee, shall inure to the benefit of the heirs, distributees, executors, administrators and other legal representatives of such person, shall survive and not be adversely affected by any modification or repeal of this Article with respect to any claim or proceeding which arose or transaction, matter, event or condition which occurred or existed before such modification or repeal and shall be binding upon all successors of the Corporation.

Section 4. Insurance.

The Corporation may purchase and maintain insurance on behalf of any person who is or was such an officer, director, partner, member, employee, agent or trustee against any expense, liability or loss asserted against such person as such an officer, director, partner, member, employee, agent or trustee or arising out of such person’s status as such an officer, director, partner, member, employee, agent or trustee, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the provisions of this Article or applicable law.

Section 5. Definition of Certain Terms.

(a) For purposes of this Article, references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Corporation” shall include any service as a director, officer, fiduciary, employee or agent of the Corporation which imposes duties on, or involves services by, such director, officer, fiduciary, employee or agent with respect to an employee benefit plan, its participants or its beneficiaries.


(b) For the purposes of this Article and the Law, a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interest of the Corporation.”

ARTICLE VI - CONTRACTS; BANK ACCOUNTS

ARTICLE VII - SHARES; DIVIDENDS

In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon any certificate shall have ceased to be such an officer, transfer agent or registrar before such certificate is issued, such certificate may be issued with the same effect as if he were such officer, transfer agent or registrar on the date of issuance of such certificate.

Section 2. Transfers.

Transfers of shares of capital stock of the Corporation shall be made on the records of the Corporation only upon authorization by the record holder of such shares, in person or by his duly authorized attorney or legal representative, and, in the case of certified shares, upon surrender and cancellation of certificates therefor duly endorsed or accompanied by duly executed stock powers (with such proof of authenticity of signature as the Corporation or its agent may require) for a like number of shares, upon payment of all taxes thereon and upon compliance with any restrictions on transfer thereof; or, in the case of uncertificated shares, upon receipt of proper transfer instructions from the registered holder of the shares or by such person’s attorney lawfully constituted in writing and upon payment of all taxes thereon and upon compliance with any restrictions on transfer thereof. The person in whose name shares of capital stock of the Corporation stand on the records of the Corporation shall be deemed the owner of such shares for all purposes as regards the Corporation.
