The ability of stockholders to call special meetings is specifically denied.

Section 4.NATURE OF BUSINESS AT ANNUAL MEETINGS. No business may be transacted at an annual meeting of stockholders other than business that is (a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors (or any duly authorized committee thereof), (b) otherwise properly brought before the annual meeting by or at the direction of the Board of Directors (or any duly authorized committee thereof), or (c) otherwise properly brought before the annual meeting by any stockholder of the Corporation (i) who is a stockholder of record on the date of the giving of the notice provided for in this Section 4 and on the record date for the determination of stockholders entitled to notice of and to vote at such annual meeting and (ii) who complies with the notice procedures set forth in this Section 4.

In addition to any other applicable requirements, for business to be properly brought before an annual meeting by a stockholder, such stockholder must have given timely notice thereof in proper written form to the secretary of the Corporation. To be timely, a stockholder’s notice to the secretary must be delivered to or mailed and received at the principal executive offices of the Corporation not less than ninety (90) days nor more than one hundred twenty (120) days prior to the anniversary date of the immediately preceding annual meeting of stockholders; provided, however, that in the event that the annual meeting is called for a date that is not within thirty (30) days before or after such anniversary date, notice by the stockholder in order to be timely must be so received not later than the close of business on the tenth (10^th) day following the day on which such notice of the date of the annual meeting was mailed or public disclosure of the date of the annual meeting was made, whichever first occurs. To be in proper written form, a stockholder’s notice to the secretary must set forth as to each matter such stockholder proposes to bring before the annual meeting (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (ii) the name and record address of such stockholder, (iii) the class or series and number of shares of capital stock of the Corporation that are beneficially owned or of record by such stockholder, (iv) a description of all arrangements or understandings between such stockholder and any other person or persons (including their names) in connection with the proposal of such business by such stockholder and any material interest of such stockholder in such business and (v) a representation that such stockholder is a holder of record of stock of the Corporation entitled to vote at such meeting and that such stockholder intends to appear in person or by proxy at the annual meeting to bring such business before the meeting. In addition, notwithstanding anything in this Section 4 to the contrary, a stockholder intending to nominate one or more persons for election as a director at an annual or special meeting of stockholders must comply with Section 5 of Article II of these By-Laws for such nominations to be properly brought before such meeting.

No business shall be conducted at the annual meeting of stockholders except business brought before the annual meeting in accordance with the procedures set forth in this Section 4; provided, however, that once business has been properly brought before the annual meeting in accordance with such procedures, nothing in this Section 4 shall be deemed to preclude discussion by any stockholder of any such business. If the chairman of an annual meeting determines that business was not properly brought before the annual meeting in accordance with the foregoing procedures, the chairman shall declare to the meeting that the business was not properly brought before the meeting and such business shall not be transacted.

Section 5.NOMINATION OF DIRECTORS.

No person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth in this Section 5.

If mailed, such notice shall be deemed to be given when deposited in the United States mail addressed to the stockholder at his post office address as it appears on the records of the Corporation, with postage thereon prepaid.

Section 7.ADJOURNMENTS. Any meeting of the stockholders may be adjourned from time to time to reconvene at the same or some other place, and, except as provided herein, notice need not be given of any such adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting, the Corporation may transact any business that might have been transacted at the original meeting. If the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, notice of the adjourned meeting in accordance with the requirements of Section 6 of this Article II shall be given to each stockholder of record entitled to notice of and to vote at the meeting.

Section 8.QUORUM. At any meeting of stockholders, the presence in person or by proxy of stockholders entitled to cast a majority of all the votes entitled to be cast at such meeting shall constitute a quorum; but this section shall not affect any requirement under any statute or the Certificate of Incorporation of Corporation for the vote necessary for the adoption of any measure. If, however, such quorum shall not be present at any meeting of the stockholders, the stockholders entitled to vote at such meeting, present in person or by proxy, shall have the power to adjourn the meeting in accordance with Section 7 of this Article II.

Section 9.VOTING.. A plurality of all the votes cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to elect a director. Each share may be voted for as many individuals as there are directors to be elected and for whose election the share is entitled to be voted. A majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to approve any other matter which may properly come before the meeting, unless more than a majority of the votes cast is required by statute or by the Certificate of Incorporation of the Corporation. Unless otherwise provided in the Certificate of Incorporation, each outstanding share, regardless of class, shall be entitled to one vote on each matter submitted to a vote at a meeting of stockholders.

Section 10.PROXIES. A stockholder may vote the stock owned of record by him, either in person or by proxy executed in writing by the stockholder or by his duly authorized attorney in fact. Such proxy shall be filed with the secretary of the Corporation before or at the time of the meeting. No proxy shall be valid after eleven months from the date of its execution, unless otherwise provided in the proxy. A stockholder may authorize another person or persons to act for such stockholder as proxy by executing a writing containing such stockholder’s signature affixed to such writing by any reasonable means, including, but not limited to, facsimile.

Section 11.VOTING OF STOCK BY CERTAIN HOLDERS. Stock registered in the name of a corporation, partnership, trust or other entity, if entitled to be voted, may be voted by the president or a vice president, a general partner or trustee thereof, as the case may be, or a proxy appointed by any of the foregoing individuals, unless some other person who has been appointed to vote such stock pursuant to a bylaw or a resolution of the board of directors of such corporation or other entity or agreement of the partners of a partnership presents a certified copy of such bylaw, resolution or agreement, in which case such person may vote such stock. Any director or other fiduciary may vote stock registered in his name as such fiduciary, either in person or by proxy.

Shares of stock of the Corporation directly or indirectly owned by it shall not be voted at any meeting and shall not be counted in determining the total number of outstanding shares entitled to be voted at any given time, unless they are held by it in a fiduciary capacity, in which case they may be voted and shall be counted in determining the total number of outstanding shares at any given time.

The Board of Directors may adopt by resolution a procedure by which a stockholder may certify in writing to the Corporation that any shares of stock registered in the name of the stockholder are held for the account of a specified person other than the stockholder. The resolution shall set forth the class of stockholders who may make the certification, the purpose for which the certification may be made, the form of certification and the information to be contained in it; if the certification is with respect to a record date or closing of the stock transfer books, the time after the record date or closing of the stock transfer books within which the certification must be received by the Corporation; and any other provisions with respect to the procedure which the Board of Directors considers necessary or desirable. On receipt of such certification, the person specified in the certification shall be regarded as, for the purposes set forth in the certification, the stockholder of record of the specified stock in place of the stockholder who makes the certification.

Section 12.LIST OF STOCKHOLDERS ENTITLED TO VOTE. The officer of the Corporation who has charge of the stock ledger of the Corporation shall prepare and make, at least ten (10) days before every meeting of the stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting (i) either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held or (ii) during ordinary business hours, at the principal place of business of the Corporation. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. The stock ledger of the Corporation shall be the only evidence as to who are the stockholders entitled to examine the stock ledger, the list required by this Section or the books of the Corporation, or to vote in person or by proxy at any meeting of the stockholders.

Section 13.RECORD DATE. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of the stockholders or any adjournment thereof, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, 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 of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of the stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of the stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting in accordance with Section 7 of this Article II.

Section 14.CONDUCT OF MEETINGS. The Board of Directors of the Corporation may adopt by resolution such rules and regulations for the conduct of any meeting of the stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules and regulations as adopted by the Board of Directors, the chairman of any meeting of the stockholders shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairman, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the chairman of the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) the determination of when the polls shall open and close for any given matter to be voted on at the meeting; (iii) rules and procedures for maintaining order at the meeting and the safety of those present; (iv) limitations on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as the chairman of the meeting shall determine; (v) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (vi) limitations on the time allotted to questions or comments by participants.

Section 15.INSPECTORS. At any meeting of stockholders, the chairman of the meeting may, or upon the request of any stockholder shall, appoint one or more persons as inspectors for such meeting. Such inspectors shall ascertain and report the number of shares represented at the meeting based upon their determination of the validity and effect of proxies, count all votes, report the results and perform such other acts as are proper to conduct the election and voting with impartiality and fairness to all the stockholders.

Each report of an inspector shall be in writing and signed by him or by a majority of them if there is more than one inspector acting at such meeting. If there is more than one inspector, the report of a majority shall be the report of the inspectors. The report of the inspector or inspectors on the number of shares represented at the meeting and the results of the voting shall be prima facie evidence thereof.

STOCK

Section 1.CERTIFICATES; UNCERTIFICATED SHARES. The shares of stock of the Corporation shall be represented by certificates, or by uncertificated shares that may be evidenced by a book-entry system maintained by the registrar of such stock, or a combination of both, as permitted by, and in accordance with, the Delaware General Corporation Law. If shares are represented by certificates (if any), such certificates shall be in the form approved by the Board of Directors.

When authorizing such issue of a new certificate or uncertificated shares, 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 such owner’s legal representative, to advertise the same in such manner as the Corporation shall require and/or give the Corporation a bond in such sum as it may direct as indemnity against any claim that may be made against the Corporation or its transfer agent or registrar with respect to the certificate alleged to have been lost, stolen or destroyed.

Section 4.CLOSING OF TRANSFER BOOKS OR FIXING OF RECORD DATE. The Board of Directors may set, in advance, a record date for the purpose of determining stockholders entitled to notice of or to vote at any meeting of stockholders or determining stockholders entitled to receive payment of any dividend or the allotment of any other rights, or in order to make a determination of stockholders for any other proper purpose. Such date, in any case, shall not be prior to the close of business on the day the record date is fixed and shall be not more than 60 days and, in the case of a meeting of stockholders, not less than ten days, before the date on which the meeting or particular action requiring such determination of stockholders is to be held or taken.

In lieu of fixing a record date, the Board of Directors may provide that the stock transfer books shall be closed for a stated period but not longer than 20 days. If the stock transfer books are closed for the purpose of determining stockholders entitled to notice of or to vote at a meeting of stockholders, such books shall be closed for at least ten days before the date of such meeting.

If no record date is fixed and the stock transfer books are not closed for the determination of stockholders, (a) the record date for the determination of stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day on which the notice of meeting is mailed or the 30th day before the meeting, whichever is the closer date to the meeting; and (b) the record date for the determination of stockholders entitled to receive payment of a dividend or an allotment of any other rights shall be the close of business on the day on which the resolution of the directors, declaring the dividend or allotment of rights, is adopted.

ARTICLE XI

INDEMNIFICATION AND ADVANCES FOR EXPENSES

SECTION 1.POWER TO INDEMNIFY IN ACTIONS, SUITS OR PROCEEDINGS OTHER THAN THOSE BY OR IN THE RIGHT OF THE CORPORATION. Subject to Section 3 of this Article XI, the Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation), by reason of the fact that such person is or was a director or officer of the Corporation, or is or was a director or officer of the Corporation serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a pleas of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that such person’s conduct was lawful.

15

SECTION 2.POWER TO INDEMNIFY IN ACTIONS, SUITS OR PROCEEDINGS BY OR IN THE RIGHT OF THE CORPORATION. Subject to Section 3 of this Article XI, the Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Corporation, or is or was a director or officer of the Corporation serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

SECTION 3.AUTHORIZATION OF INDEMNIFICATION. Any indemnification under this Article XI (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the present or former director or officer is proper in the circumstances because such person has met the applicable standard of conduct set forth in Section 1 or Section 2 of this Article XI, as the case may be. Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (i) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by a majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion or (iv) by the stockholders. Such determination shall be made, with respect to former directors and officers, by any person or persons having the authority to act on the matter on behalf of the Corporation. To the extent, however, that a present or former director or officer of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith, without the necessity of authorization in the specific case.

16

SECTION 4.GOOD FAITH DEFINED. For purposes of any determination under Section 3 of this Article XI, a person shall be deemed to have acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, or, with respect to any criminal action or proceeding, to have had no reasonable cause to believe such person’s conduct was unlawful, if such person’s action is based on the records or books of account of the Corporation or another enterprise, or on information supplied to such person by the officers of the Corporation or another enterprise in the course of their duties, or on the advice of legal counsel for the Corporation or another enterprise or on information or records given or reports made to the Corporation or another enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Corporation or another enterprise. The provisions of this Section 4 shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of conduct set forth in Section 1 or Section 2 of this Article XI, as the case may be.

SECTION 5.INDEMNIFICATION BY A COURT. Notwithstanding any contrary determination in the specific case under Section 3 of this Article XI, and notwithstanding the absence of any determination thereunder, any director or officer may apply to the Court of Chancery of the State of Delaware or any other court of competent jurisdiction in the State of Delaware for indemnification to the extent otherwise permissible under Section 1 or Section 2 of this Article XI. The basis of such indemnification by a court shall be a determination by such court that indemnification of the director or officer is proper in the circumstances because such person has met the applicable standard of conduct set forth in Section 1 or Section 2 of this Article XI, as the case may be. Neither a contrary determination in the specific case under Section 3 of this Article XI nor the absence of any determination thereunder shall be a defense to such application or create a presumption that the director or officer seeking indemnification has not met any applicable standard of conduct. Notice of any application for indemnification pursuant to this Section 5 shall be given to the Corporation promptly upon the filing of such application. If successful, in whole or in part, the director or officer seeking indemnification shall also be entitled to be paid the expense of prosecuting such application.

SECTION 6.EXPENSES PAYABLE IN ADVANCE. Expenses (including attorneys’ fees) incurred by a present or former director or officer in defending any civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation as authorized in this Article XI. Such expenses (including attorneys’ fees) incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Corporation deems appropriate.

17

SECTION 7.NONEXCLUSIVELY OF INDEMNIFICATION AND ADVANCEMENT OF EXPENSES. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article XI shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under the Certificate of Incorporation, these By-Laws, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office, it being the policy of the Corporation that indemnification of the persons specified in Section 1 and Section 2 of this Article XI shall be made to the fullest extent permitted by law. The provisions of this Article XI shall not be deemed to preclude the indemnification of any person who is not specified in Section 1 or Section 2 of this Article XI but whom the Corporation has the power or obligation to indemnify under the provisions of the Delaware General Corporation Law, or otherwise.

SECTION 8.INSURANCE. The Corporation may purchase and maintain insurance on behalf of any person who is or was a director of officer of the Corporation or is or was a director or officer of the Corporation serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Corporation would have the power or the obligation to indemnify such person against such liability under the provisions of this Article XI.

SECTION 9.CERTAIN DEFINITIONS. For purposes of this Article XI, references to “the Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors or officers, so that any person who is or was a director or officer of such constituent corporation, or is or was a director or officer of such constituent corporation serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article XI with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued. The term “another enterprise” as used in this Article XI shall mean any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise of which such person is or was serving at the request of the Corporation as a director, officer, employee or agent. For purposes of this Article XI, 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, employee or agent of the Corporation which imposes duties on, or involves services by, such director or officer with respect to an employee benefit plan, its participants or beneficiaries; and 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 interests of the Corporation” as referred to in this Article XI.

SECTION 10.SURVIVAL OF INDEMNIFICATION AND ADVANCEMENT OF EXPENSES. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article XI shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

18

SECTION 11.LIMITATION ON INDEMNIFICATION. Notwithstanding anything contained in this Article XI to the contrary, except for proceedings to enforce rights to indemnification (which shall be governed by Section 5 of this Article XI), the Corporation shall not be obligated to indemnify any director or officer (or his or her heirs, executors or personal or legal representatives) or advance expenses in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or party thereof) was authorized or consented to by the Board of Directors of the Corporation.

SECTION 12.INDEMNIFICATION OF EMPLOYEES AND AGENTS. The Corporation may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification and to the advancement of expenses to employees and agents of the Corporation similar to those conferred in this Article XI to directors and officers of the Corporation.

ARTICLE XII

WAIVER OF NOTICE

Whenever any notice is required to be given pursuant to the Certificate of Incorporation of the Corporation or these By-Laws or pursuant to applicable law, waiver thereof in writing, signed by the person or persons entitled to such notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice. Neither the business to be transacted at nor the purpose of any meeting need be set forth in the waiver of notice, unless specifically required by statute. The attendance of any person at any meeting, in person or by proxy, shall constitute a waiver of notice of such meeting, except where such person attends a meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

ARTICLE XIII

AMENDMENT OF BY-LAWS

These By-Laws may be altered, amended or repealed or new By-Laws may be adopted by the stockholders or by the Board of Directors, to the extent that such power is conferred upon the Board of Directors by the Certificate of Incorporation, at any regular meeting of the stockholders or of the Board of Directors or at any special meeting of the stockholders or of the Board of Directors if notice of such proposed alteration, amendment, repeal or adoption of new By-Laws shall be contained in the notice of such special meeting.
