Section 2. Annual Meeting. An annual meeting of the stockholders of the Corporation for the election of directors by written ballot and for the transaction of such other business as may properly come before the meeting shall be held at such time and on such day of each year as shall be designated by the Board of Directors, the Chairman of the Board, the President or the Secretary.

Section 3. Notice of Stockholder Nominations of Directors. Only persons who are nominated in accordance with the following procedures shall be eligible for election as directors of the Corporation, except as may be otherwise provided in the Restated Certificate of Incorporation of the Corporation. Nominations of persons for election to the Board of Directors may be made at any annual meeting of stockholders (a) by or at the direction of the Board of Directors (or any duly authorized Committee thereof) or (b) 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 3 and on the record date for the determination of stockholders entitled to vote at such annual meeting and (ii) who complies with the notice procedures set forth in this Section 3.

In addition to any other applicable requirements, for a nomination to be made 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 (a) in the case of an Annual Meeting, not less than one hundred twenty (120) days nor more than one hundred fifty (150) 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 an 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 (10th) 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; and (b) in the case of a Special Meeting called for the purpose of electing directors, not later than the close of business on the tenth (10th) day following the day on which notice of the date of the Special Meeting was mailed or public disclosure of the date of the Special Meeting was made, whichever first occurs. In no event shall the public disclosure of an adjournment of an annual meeting commence a new time period for the giving of a stockholder’s notice as described above.

To be in proper written form, a stockholder’s notice to the Secretary must set forth as to each person whom the stockholder proposes to nominate for election as a director and as to the stockholder giving the notice and any Stockholder Associated Person (as defined below) (i) the name, age, business address, residence address and record address of such person, (ii) the principal occupation or employment of such person, (iii) the class or series and number of shares of capital stock of the Corporation which are owned beneficially or of record by such person, (iv) any information relating to such person 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 election of directors pursuant to Section 14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, (v) the nominee holder for, and number of, shares owned beneficially but not of record by such person, (vi) whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including any derivative or short positions, profit interests, options or borrowed or loaned shares) has been made, the effect or intent of which is to mitigate loss to or manage risk or benefit of share price changes for, or to increase or decrease the voting power of, such person with respect to any share of stock of the Corporation, (vii) to the extent known by the stockholder giving the notice, the name and address of any other stockholder supporting the nominee for election or reelection as a director on the date of such stockholder’s notice, (viii) a description of all arrangements or understandings between or among such persons pursuant to which the nomination(s) are to be made by the stockholder and (ix) a representation that such stockholder intends to appear in person or by proxy at the meeting to nominate the persons named in its notice. Any ownership information shall be supplemented by the stockholder giving the notice not later than ten (10) days after the record date for the

meeting as of the record date. Such notice must be accompanied by a written consent of each proposed nominee to being named as a nominee and to serve as a director if elected. The Corporation may require any proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine the eligibility of such proposed nominee to serve as an independent director of the Corporation or that could be material to a reasonable stockholder’s understanding of the independence, or lack thereof, of such nominee.

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 3. If the Chairman of the meeting determines that a nomination was not made in accordance with the foregoing procedures, the Chairman shall declare to the meeting that the nomination was defective and such defective nomination shall be disregarded.

Notwithstanding anything in the third paragraph of this Section 3 to the contrary, in the event that the number of directors to be elected to the Board of Directors of the Corporation is increased and there is no public disclosure by the Corporation naming all of the nominees for director 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 stockholder’s notice required by this By-Law shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the tenth (10th) day following the day on which such public disclosure is first made by the Corporation.

Section 4. Notice of Stockholder Proposals of Business. No business may be transacted at an annual meeting of stockholders, other than business that is either: (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 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 one hundred twenty (120) days nor more than one hundred fifty (150) 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 (10th) 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. In no event shall the public disclosure of an adjournment of an annual meeting commence a new time period for the giving of a stockholder’s notice as described above.

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 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 and as to the stockholder giving the notice and any Stockholder Associated Person (i) the name and record address of such person, (ii) the class or series and number of shares of capital stock of the Corporation which are owned beneficially or of record by such person, (iii) the nominee holder for, and number of, shares owned beneficially but not of record by such person, (iv) whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including any derivative or short positions, profit interests, options or borrowed or loaned shares) has been made, the effect or intent of which is to mitigate loss to or manage risk or benefit of share price changes for, or to increase or decrease the voting power of, such person with respect to any share of stock of the Corporation, (v) to the extent known by the stockholder giving the notice, the name and address of any other stockholder supporting the proposal of other business on the date of such stockholder’s notice, (vi) a description of all arrangements or understandings between or among such persons in connection with the proposal of such business by such stockholder and any material interest in such business and (vii) a representation that the stockholder giving the notice intends to appear in person or by proxy at the annual meeting to bring such business before the meeting. Any ownership information shall be supplemented by the stockholder giving the notice not later than ten (10) days after the record date for the meeting as of the record date.

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. Definitions. For purposes of Sections 3 and 4 of Article II of these By-Laws:

“Public disclosure” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.”

“Stockholder Associated Person” of any stockholder shall mean (i) any person acting in concert, directly or indirectly, with such stockholder and (ii) any person controlling, controlled by or under common control with such stockholder or any Stockholder Associated Person.

Section 6. Special Meetings.

(a) Special meetings of the stockholders, for any purpose or purposes, unless otherwise prescribed by statute, may be called at any time by the Board of Directors or by the Chairman of the Board, and shall be called by the Chairman of the Board, the President or the Secretary at the written request of the majority of the Board of Directors or at the written request, in accordance with this Section 6, of stockholders owning capital stock having twenty-five percent (25%) of the voting power of the entire issued and outstanding capital stock of the Corporation. Such request shall state the purpose or purposes of the proposed meeting. No business shall be transacted at any special meeting of the stockholders except that stated in the notice of the meeting.

(b) In order that the Corporation may determine the stockholders entitled to demand a special meeting, the Board of Directors may fix a record date to determine the stockholders entitled to make such a demand (the “Demand Record Date”). The Demand Record Date shall not precede the date upon which the resolution fixing the Demand Record Date is adopted by the Board of Directors and shall not be more than ten (10) days after the date upon which the resolution fixing the Demand Record Date is adopted by the Board of Directors. Any stockholder of record seeking to have stockholders demand a special meeting shall, by sending written notice to the Secretary of the Corporation by hand or by certified or registered mail, return receipt requested, request the Board of Directors to fix a Demand Record Date. The Board of Directors shall promptly, but in all events within ten (10) days after the date on which a valid request to fix a Demand Record Date is received, adopt a resolution fixing the Demand Record Date and shall make a public announcement of such Demand Record Date. If no Demand Record Date has been fixed by the Board of Directors within ten (10) days after the date on which such request is received by the Secretary, the Demand Record Date shall be the tenth (10th) day after the first date on which a valid written request to set a Demand Record Date is received by the Secretary. To be valid, such written request shall set forth the purpose or purposes for which the special meeting is to be held, shall be signed by one or more stockholders of record (or their duly authorized proxies or other representatives), shall bear the date of signature of each such stockholder (or proxy or other representative) and shall set forth all information about each such stockholder and about the beneficial owner or owners, if any, on whose behalf the request is made that would be required to be set forth in a stockholder’s notice described in Section 3 of Article II of these By-Laws.

(c) In order for a stockholder or stockholders to demand a special meeting, a written demand or demands for a special meeting by the holders of record as of the

Demand Record Date of not less than twenty-five percent (25%) of the voting power of the entire issued and outstanding capital stock of the Corporation entitled to vote on the matter proposed to be considered at the special meeting must be delivered to the Corporation. To be valid, each written demand by a stockholder for a special meeting shall set forth the specific purpose or purposes for which the special meeting is to be held (which purpose or purposes shall be limited to the purpose or purposes set forth in the written request to set a Demand Record Date received by the Corporation pursuant to paragraph (b) of this Section 6), shall be signed by one or more persons who as of the Demand Record Date are stockholders of record (or their duly authorized proxies or other representatives), shall bear the date of signature of each such stockholder (or proxy or other representative), shall set forth the name and address, as they appear in the Corporation’s books, of each stockholder signing such demand and the class and number of shares of the Corporation which are owned of record and beneficially by each such stockholder, shall be sent to the Secretary by hand or by certified or registered mail, return receipt requested, and shall be received by the Secretary within sixty (60) days after the Demand Record Date.

(d) The Corporation shall not be required to call a special meeting upon stockholder demand unless, in addition to the documents required by paragraph (c) of this Section 6, the Secretary receives a written agreement signed by each Soliciting Stockholder (as defined below), pursuant to which each Soliciting Stockholder, jointly and severally, agrees to pay the Corporation’s costs of holding the special meeting, including the costs of preparing and mailing proxy materials for the Corporation’s own solicitation, provided that if each of the resolutions introduced by any Soliciting Stockholder at such meeting is adopted, and each of the individuals nominated by or on behalf of any Soliciting Stockholder for election as a director at such meeting is elected, then the Soliciting Stockholders shall not be required to pay such costs. For purposes of this paragraph (d), the following terms shall have the meanings set forth below:

(i) “Affiliate” of any Person (as defined herein) shall mean any Person controlling, controlled by or under common control with such first Person.

(ii) “Participant” shall have the meaning assigned to such term in Instruction 3 of Item 4 of Schedule 14A promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)

(iii) “Person” shall mean any individual, firm, corporation, partnership, joint venture, association, trust, unincorporated organization or other entity.

(iv) “Proxy” shall have the meaning assigned to such term in Rule 14a-1 promulgated under the Exchange Act.

(v) “Solicitation” shall have the meaning assigned to such term in Rule 14a-1 promulgated under the Exchange Act.

(vi) “Soliciting Stockholder” shall mean, with respect to any special meeting demanded by a stockholder or stockholders, any of the following Persons: (A) if the number of stockholders signing the demand or demands of meeting delivered to the corporation pursuant to paragraph (c) of this Section 6 is 10 or fewer, each stockholder signing any such demand; (B) if the number of stockholders signing the demand or demands of meeting delivered to the corporation pursuant to paragraph (c) of this Section 6 is more than 10, each Person who either (x) was a Participant in any Solicitation of such demand or demands or (y) at the time of the delivery to the Corporation of the documents described in paragraph (c) of this Section 6 had engaged or intended to engage in any Solicitation of Proxies for use at such special meeting (other than a Solicitation of Proxies on behalf of the Corporation); or (C) any Affiliate of a Soliciting Stockholder, if a majority of the directors then in office determine, reasonably and in good faith, that such Affiliate should be required to sign the written notice described in paragraph (c) of this Section 6 and/or the written agreement described in this paragraph (d) in order to prevent the purposes of this Section 6 from being evaded.

(e) Except as provided in the following sentence, any special meeting shall be held at such hour and day as may be designated by whichever of the Chairman of the Board, President or Secretary shall have called such meeting. In the case of any special meeting called by the Chairman of the Board, President or Secretary upon the demand of stockholders (a “Demand Special Meeting”), such meeting shall be held at such hour and day as may be designated by the Chairman of the Board, President or Secretary; provided, however, that the date of any Demand Special Meeting shall be not more than sixty (60) days after the Record Date (determined pursuant to Section 5 of Article VI of these By-Laws); and provided further that in the event that the directors then in office fail to designate an hour and date for a Demand Special Meeting within ten (10) days after the date that valid written demands for such meeting by the holders of record as of the Demand Record Date of shares representing not less than twenty-five percent (25%) of the voting power of the entire issued and outstanding capital stock of the Corporation entitled to vote on the matter proposed to be considered at the special meeting are delivered to the Corporation (the “Delivery Date”), then such meeting shall be held at 2:00 P.M. Central Time on the 90th day after the Delivery Date or, if such 90th day is not a Business Day (as defined below), on the first preceding Business Day. In fixing a meeting date for any special meeting, the Chairman of the Board, President or Secretary may consider such factors as he deems relevant within the good faith exercise of his business judgment, including, without limitation, the nature of the action proposed to be taken, the facts and circumstances surrounding any demand for such meeting, and any plan of the Board of Directors to call an annual meeting or a special meeting for the conduct of related business.

(f) The Corporation may engage independent inspectors of elections to act as an agent of the Corporation for the purpose of promptly performing a ministerial

review of the validity of any purported written demand or demands for a special meeting received by the Secretary. For the purpose of permitting the inspectors to perform such review, no purported demand shall be deemed to have been delivered to the Corporation until such date as the independent inspectors certify to the Corporation that the valid demands received by the Secretary represent not less than twenty-five percent (25%) of the voting power of the entire issued and outstanding capital stock of the Corporation entitled to vote on the matter proposed to be considered at the special meeting. Nothing contained in this paragraph (f) shall in any way be construed to suggest or imply that the Board of Directors or any stockholder shall not be entitled to contest the validity of any demand, whether during or after such five (5) Business Day period, or to take any other action (including, without limitation, the commencement, prosecution or defense of any litigation with respect thereto).

(g) For purposes of these By-Laws, “Business Day” shall mean any day other than a Saturday, a Sunday or a day on which banking institutions in the State of Minnesota are authorized or obligated by law or executive order to close.

(h) Notwithstanding anything in these By-Laws to the contrary, if the Board of Directors shall determine that any request to fix a Demand Record Date or demand a special meeting was not properly made in accordance with this Section 6, or the stockholder or stockholders seeking to take such action do not otherwise comply with this Section 6, then the Board of Directors shall not be required to fix a Demand Record Date or call a special meeting.

Section 7. Notice of Meetings. Written notice stating the place, date and hour of each annual and special meeting of the stockholders and, in the case of a special meeting, the purpose or purposes thereof, shall be given not less than ten (10) nor more than sixty (60) days before the date of such meeting to each stockholder entitled to vote at such meeting, unless otherwise required by applicable law. If mailed, notice shall be deemed given when deposited in the United States mail, postage prepaid, directed to the stockholder at such address as appears on the records of the Corporation. Notice of any meeting of stockholders shall not be required to be given to any stockholder who shall attend such meeting in person or by proxy and shall not, at the beginning of such meeting, object to the transaction of any business because the meeting is not lawfully called or convened, or who shall, either before or after the meeting, submit a signed waiver of notice.

Section 8. Quorum. At all meetings of the stockholders, the holders of a majority of the shares of stock of the Corporation issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall be requisite to constitute a quorum for the transaction of business, except as otherwise provided by statute or in the Restated Certificate of Incorporation. A quorum, once established, shall not be broken by the withdrawal of enough votes to leave less than a quorum. In the absence of a quorum, the holders of a majority of the shares of stock present in person or by proxy and entitled to vote may adjourn the meeting until the requisite amount of stock shall be present.

Section 9. Organization and Order of Business. At each meeting of the stockholders, the Chairman of the Board, or in his absence, the President, or in his absence any other person selected by the Board of Directors, shall act as Chairman of the meeting. The Secretary, or in his absence an Assistant Secretary, or any person appointed by the Chairman of the meeting, shall act as Secretary of the meeting and keep the minutes thereof. The Board of Directors 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 the 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 10. Voting. Except as otherwise provided by statute or by the Restated Certificate of Incorporation, at each meeting of the stockholders each stockholder having the right to vote thereat shall be entitled to (i) one vote for each share of common stock of the Corporation standing in his name on the record of stockholders of the Corporation, and (ii) such voting rights, if any, as are provided in the applicable Certificate of Designation, Preferences and Rights with respect to any series of preferred stock of the Corporation standing in his name on the record of stockholders of the Corporation, in all such instances on the date fixed by the Board of Directors as the record date for the determination of the stockholders who shall be entitled to notice of and vote at such meeting; or if no record date shall have been fixed, then at the close of business on the day next preceding the day on which notice thereof shall be given. Each stockholder entitled to vote at any meeting of stockholders may authorize another person or persons to act for him by a proxy signed or otherwise authorized in accordance with Section 212 of the General Corporation Law of Delaware by such stockholder or his attorney-in-fact. No proxy shall be valid after the expiration of three (3) years from the date thereof, unless otherwise provided in the proxy. Except as otherwise provided by statute, these By-Laws or the Restated Certificate of Incorporation, any corporate action to be taken by vote of the stockholders shall be authorized by a majority of the total votes cast at a meeting of stockholders by the holders of shares present in person or represented by proxy and entitled to vote on such action. Unless required by statute, or determined by the chairman of the meeting to be advisable, the vote on any question other than elections need not be by written ballot. On a vote by written ballot, each ballot shall be signed by the stockholder, his

attorney-in-fact, or his proxy if there be such proxy, and shall state the stockholder’s name and the number of shares voted.

Section 11. Stockholder List. The Secretary shall prepare and make, at least ten (10) days before every meeting of 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, 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. This 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.

Section 12. Inspectors. The Board of Directors may, in advance of any meeting of stockholders, appoint or provide for the appointment of one or more inspectors to act at such meeting or any adjournments thereof. If the inspector or inspectors shall not be appointed, or if any of them shall fail to appear or act, the Chairman of the meeting may, and on the request of any stockholder entitled to vote thereat shall, appoint one or more inspectors. Each inspector, before entering upon the discharge of his duties, shall take and sign an oath faithfully to execute the duties of inspector at such meeting with strict impartiality and according to the best of his ability. On request of the Chairman of the meeting or any stockholder entitled to vote thereat, the inspectors shall make a report in writing of any challenge, request or matter determined by them and shall execute a certificate of any fact found by them. No director or candidate for the office of director shall act as inspector of any election of directors. Inspectors need not be stockholders of the Corporation.

Section 13. Adjourned Meetings. A meeting of stockholders may be adjourned to another time and to another place by either the chairman of the meeting or by the stockholders and proxies present. When a meeting is adjourned to another time or place, notice of such adjourned meeting need not be given if the time and place to which the meeting shall be adjourned are announced at the meeting at which the adjournment is taken. At the adjourned meeting, if a quorum is present any business may be transacted which 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 shall be given to each stockholder of record entitled to vote at the meeting.

Section 14. Consent of Stockholders.

(a) Unless otherwise provided in the Restated Certificate of Incorporation, any action required or permitted to be taken at any annual or special meeting of stockholders of the Corporation, may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock of the Corporation having not less than the minimum number of votes that would be necessary to authorize or

take such action at a meeting at which all shares entitled to vote thereon were present and voted. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing.

(b) In order that the Corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date (a “Consent Record Date”). The Consent Record Date shall not precede the date upon which the resolution fixing the Consent Record Date is adopted by the Board of Directors and shall not be more than ten (10) days after the date upon which the resolution fixing the Consent Record Date is adopted by the Board of Directors. Any stockholder of record seeking to consent to corporate action in writing without a meeting shall, by sending written notice to the Secretary of the Corporation by hand or by certified or registered mail, return receipt requested, at the Corporation’s principal executive offices, request the Board of Directors to fix a Consent Record Date. The Board of Directors shall promptly, but in all events within ten (10) days after the date on which a valid request to fix a Consent Record Date is received, adopt a resolution fixing the Consent Record Date and shall make a public announcement of such Consent Record Date. If no Consent Record Date has been fixed by the Board of Directors within ten (10) days after the date on which such request is received by the Secretary, the Consent Record Date shall be the tenth (10th) day after the first date on which a valid written request to set a Consent Record Date is received by the Secretary. To be valid, such written request shall set forth the purpose or purposes for which the written consent is sought to be used, shall be signed by one or more stockholders of record (or their duly authorized proxies or other representatives), shall bear the date of signature of each such stockholder (or proxy or other representative) and shall set forth all information about each such stockholder and about the beneficial owner or owners, if any, on whose behalf the request is made that would be required to be set forth in a stockholder’s notice described in Section 3 of Article II of these By-Laws.

(c) Every written consent shall be signed by one or more persons who as of the Consent Record Date are stockholders of record on the Consent Record Date (or their duly authorized proxies or other representatives), shall bear the date of signature of each such stockholder (or proxy or other representative), and shall set forth the name and address, as they appear in the Corporation’s books, of each stockholder signing such consent and the class and number of shares of the Corporation which are owned of record and beneficially by each such stockholder and shall be sent to the Secretary by hand or by certified or registered mail, return receipt requested. No written consent shall be effective to take the corporate action referred to therein unless, within sixty (60) days of the date the earliest dated written consent was received in accordance with this paragraph (c) of this Section 14, a written consent or consents signed by a sufficient number of holders to take such action are delivered to the Corporation.

(d) In the event of the delivery, in the manner provided by paragraph (c) of this Section 14, to the Corporation of the requisite written consent or consents to

take corporate action and/or any related revocation or revocations, the Corporation may engage independent inspectors of elections for the purpose of performing a ministerial review of the validity of the consents and revocations. For the purpose of permitting the inspectors to perform such review, no action by written consent without a meeting shall be effective until such date as the independent inspectors certify to the Corporation that the consents represent at least the minimum number of votes that would be necessary to take the corporate action. Nothing contained in this paragraph (d) of Section 14 shall in any way be construed to suggest or imply that the Board of Directors or any stockholder shall not be entitled to contest the validity of any consent or revocation thereof, whether before or after certification by the independent inspectors, or to take any other action (including, without limitation, the commencement, prosecution or defense of any litigation with respect thereto, and the seeking of injunctive relief in such litigation).

(e) Notwithstanding anything in these By-Laws to the contrary, no action may be taken by the stockholders by written consent except in accordance with this Section 14. If the Board of Directors shall determine that any request to fix a Consent Record Date or to take stockholder action by written consent was not properly made in accordance with this Section 14, or the stockholder or stockholders seeking to take such action do not otherwise comply with this Section 14, then the Board of Directors shall not be required to fix a Consent Record Date and any such purported action by written consent shall be null and void to the fullest extent permitted by applicable law.

ARTICLE III

BOARD OF DIRECTORS

Section 1. General Powers. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. The Board of Directors may exercise all such authority and powers of the Corporation and do all such lawful acts and things as are not by statute or the Restated Certificate of Incorporation or these By-Laws directed or required to be exercised or done by the stockholders.

Section 2. Number and Election of Directors. The number of directors of the Corporation which shall constitute the entire Board of Directors shall be such number as is fixed by the Board of Directors in accordance with the provisions of the Restated Certificate of Incorporation. Directors shall be elected and shall hold office in accordance with the provisions of the Restated Certificate of Incorporation. Directors need not be stockholders of the Corporation.

Section 3. Required Vote for Directors. A nominee for director shall be elected to the Board of Directors by the vote of the majority of the votes cast at any meeting for the election of directors at which a quorum is present; provided, however, that directors shall be elected by a plurality of the votes cast at any meeting of stockholders for which
