Section 2. Other Events

Item 2.01 Completion of Acquisition or Disposition of Assets.

On March 31, 2008, VeraSun Energy Corporation (“VeraSun”) completed the closing of the merger (the “Merger”) with US BioEnergy Corporation (“US BioEnergy”), pursuant to the Agreement and Plan of Merger, dated as of November 29, 2007, by and among VeraSun, Host Acquisition Corporation (a direct, wholly-owned subsidiary of VeraSun) and US BioEnergy (the “Merger Agreement”), with the Merger becoming effective on April 1, 2008.

In the Merger, each outstanding share of US BioEnergy common stock was converted into 0.810 shares of VeraSun common stock (plus cash in lieu of fractional shares) and each outstanding US BioEnergy stock option and restricted stock award issued under a US BioEnergy equity-based compensation plan was converted into a VeraSun stock option or restricted stock award, as applicable, in each case on the same terms and conditions as were applicable under such US BioEnergy equity-based compensation plan. As a result of the Merger, former US BioEnergy shareholders own approximately 41.0% of the outstanding shares of VeraSun common stock. Additional information regarding the Merger may be found in the press release issued by VeraSun in connection with the announcement of the completion of the Merger, which is filed as Exhibit 99.1 to this Current Report on Form 8-K and incorporated herein by reference.

This description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement filed as Exhibit 2.1 to this Current Report on Form 8-K, which is incorporated herein by reference.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

Effective March 31, 2008, VeraSun amended the change in control agreements it had entered into on November 28, 2007 (the “Original CIC Agreements”) with each of Donald L. Endres, Chief Executive Officer, Danny C. Herron, President and Chief Financial Officer, William L. Honnef, Senior Vice President, Strategic Initiatives and John M. Schweitzer, Senior Vice President, General Counsel and Corporate Secretary, and certain other officers of VeraSun to extend the period to exercise options and other equity awards for any such officer who either is of or, during the severance period applicable to such officer, would reach VeraSun’s normal retirement age (62 years with five years of service or 65 years) to the date that is the earlier of (x) five years after the officer’s date of termination (instead of two years in the Original CIC Agreements), (y) the expiration of the award under its terms, or (z) the tenth anniversary of the original date of the award. The Original CIC Agreements, which remain otherwise unchanged, are described in VeraSun’s Current Report on Form 8-K filed on Decmber 3, 2007, which is incorporated herein by reference.

Effective April 1, 2008, VeraSun appointed James E. Dauwalter as a Director and Member of the Compensation Committee and Nominating and Corporate Governance Committee of VeraSun, Jay D. Debertin as a Director of VeraSun, Gordon W. Ommen as a Director and Non-Executive Chairman of the Board of VeraSun and Mark A. Ruelle as a Director and Chairman of the Audit Committee of VeraSun.

John M. Schweitzer resigned from his position as VeraSun’s Senior Vice President, General Counsel and Secretary effective April 1, 2008 and will retire as an employee of VeraSun on May 1, 2008.

The corporation may have such other offices, either within or without the State of South Dakota, as the Board of Directors may designate or as the business of the corporation may require from time to time.

Section 1.2 Registered Office: The registered office of the corporation required by the South Dakota Business Corporation Act to be maintained in the State of South Dakota may be, but need not be, identical with the principal office in the State of South Dakota and the address of the registered office may be changed from time to time by the Board of Directors.

Section 1.3 Registered Agent: The registered agent of the corporation required by the South Dakota Business Corporation Act to be maintained in the State of South Dakota shall be the registered agent of the corporation appointed by the Articles of Incorporation of the corporation (as amended from time to time, the “Articles of Incorporation”).

SECTION 2

Shareholders

Section 2.1 Annual Meeting: The annual meeting of the shareholders shall be held on the third Wednesday in the month of May in each year, beginning with the year 2006, or at such other date as shall be fixed by or pursuant to action of the Board of Directors, at the hour designated in the notice of said meeting, for the purpose of electing directors and for the transaction of such other business as may come before the meeting.

Section 2.2 Special Meetings: Special meetings of the shareholders, for any purpose or purposes, unless otherwise prescribed by statute, may be called by the Chairman of the Board, the Chief Executive Officer, the President or by the Board of

Directors, and shall be called by the Chairman of the Board, the Chief Executive Officer or the President at the request of the holders of not less than one-tenth (1/10^th) of all the outstanding shares of the corporation entitled to vote at the meeting.

Section 2.3 Place of Meeting: The Board of Directors may designate any place, either within or without the State of South Dakota, as the place of meeting for any annual meeting or for any special meeting called by the Board of Directors. A waiver of notice signed by all shareholders entitled to vote at a meeting may designate any place, either within or without the State of South Dakota, as the place for the holding of such meeting. If no designation is made, or if a special meeting be otherwise called, the place of meeting shall be the registered office of the corporation in the State of South Dakota.

Section 2.4 Notice of Meeting: Except for the increase of stock and indebtedness of the corporation when sixty (60) days’ notice is required by Article XVII, Section 8, of the Constitution of the State of South Dakota, written or printed notice stating the place, day and hour of the meeting and, in case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered not less than ten (10) nor more than sixty (60) days before the date of the meeting, either personally or by mail, by or at the direction of the Chairman of the Board, the Chief Executive Officer, the President, or the Secretary, or the officer or persons calling the meeting, to each shareholder of record entitled to vote at such meeting. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail, addressed to the shareholder at the shareholder’s address as it appears on the stock transfer books of the corporation, with postage thereon prepaid.

Section 2.5 Closing of Transfer Books or Fixing of Record Date: For the purpose of determining shareholders entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof, or shareholders entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other proper purpose, the Board of Directors of the corporation may provide that the stock transfer books shall be closed for a stated period but not to exceed, in any case, seventy (70) days. If the stock transfer books shall be closed for the purpose of determining shareholders entitled to notice of or to vote at a meeting of shareholders, such books shall be closed for at least ten (10) days immediately preceding such meeting. In lieu of closing the stock transfer books, the Board of Directors may fix in advance a date as the record date for any such determination of shareholders, such date in any case to be not more than seventy (70) days and, in case of a meeting of shareholders, not less than ten (10) days prior to the date on which the particular action, requiring such determination of shareholders, is to be taken. If the stock transfer books are not closed and no record date is fixed for the determination of shareholders entitled to receive notice of or to vote at a meeting of shareholders, or shareholders entitled to receive payment of a dividend, the close of business on the day on which notice of the meeting is mailed or the date on which the resolution of the Board of Directors declaring such dividend is adopted, as the case may be, shall be the record date for such determination of shareholders. When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this Section, such determination shall apply to any adjournment thereof.

Section 2.6 Voting Lists: The officer or agent having charge of the stock transfer books for shares of the corporation shall make, at least two (2) business days after notice of a meeting of shareholders is given, a complete list of the shareholders entitled to vote at such a meeting, or any adjournment thereof, arranged in alphabetical order, with the address of and the number of shares held by each, which list, beginning two (2) business days after such notice is given, shall be kept on file at the principal office of the corporation and shall be subject to inspection by any shareholder at any time during usual business hours. Such list shall also be produced and kept open at the time and place and for the whole of the meeting and shall be prima facie evidence as to who are the shareholders entitled to examine such list or transfer books or to vote at any meeting of shareholders. Failure to comply with the requirements of this Section shall not affect the validity of any action taken at such meeting.

Section 2.7 Quorum: A majority of the outstanding shares of the corporation entitled to vote, represented in person or by proxy, shall constitute a quorum at a meeting of shareholders. If less than a majority of the outstanding shares are represented at a meeting, a majority of the shares so represented may adjourn the meeting from time to time without further notice. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally notified. The shareholders present at a duly organized meeting may continue to transact business until adjournment notwithstanding the withdrawal of enough shareholders to leave less than a quorum.

Section 2.8 Proxies: A shareholder or the shareholder’s agent or attorney-in-fact may appoint a proxy to vote or otherwise act for the shareholder by signing an appointment form, or by an electronic transmission. An appointment of a proxy is effective when a signed appointment form or an electronic transmission of the appointment is received by the inspector of election or the Secretary. An electronic transmission shall contain or shall be accompanied by information from which it can be determined that the shareholder or the shareholder’s agent or attorney-in-fact authorized the transmission in such manner as the Board of Directors may determine. No proxy shall be valid after eleven (11) months from the date of its execution, unless otherwise provided in the proxy.

Section 2.9 Voting of Shares: Subject to the provisions of Section 2.11, and except to the extent that voting rights of the shares of any class or classes are limited or denied by the Articles of Incorporation, each outstanding share entitled to vote shall be entitled to one (1) vote by the holder thereof in person or by proxy, as provided in Section 2.8, upon each matter submitted to a vote at a meeting of shareholders.

Section 2.10 Voting of Shares by Certain Holders: Shares standing in the name of another corporation may be voted by such officer, agent or proxy as the bylaws of such corporation may prescribe, or, in the absence of such provision, as the board of directors of such other corporation may determine.

Shares held by an administrator, executor, guardian or conservator may be voted by him, her or it, either in person or by proxy, without a transfer of such shares into his,

her or its name. Shares standing in the name of a trustee may be voted by such trustee, either in person or by proxy, but no trustee shall be entitled to vote shares held by such trustee without a transfer of such shares into such trustee’s name.

Shares standing in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without the transfer thereof into such receiver’s name if authority so to do be contained in an appropriate order of the court by which such receiver was appointed.

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

Shares of its own stock belonging to the corporation or held by it in a fiduciary capacity shall not be voted, directly or indirectly, at any meeting and shall not be counted in determining the total number of outstanding shares at any given time.

Section 2.11 Cumulative Voting: At each election for directors every shareholder entitled to vote at such election shall have the right to vote, in person or by proxy, the number of shares owned by such shareholder for as many persons as there are directors to be elected and for whose election such shareholder has a right to vote, or to cumulate such shareholder’s votes by giving one candidate as many votes as the number of such directors multiplied by the number of shares owned by such shareholder shall equal, or by distributing such votes on the same principle among any number of candidates.

Section 2.12 Waiver of Notice: Whenever any notice is required to be given to any shareholder under the Articles of Incorporation, these Bylaws or any provision of law, a waiver thereof, signed by the person entitled to such notice, whether before or after the time stated therein, shall be equivalent to the giving of such notice.

Section 2.13 Informal Action by Shareholders: Any action required to be taken at a meeting of the shareholders, or any other action which may be taken at a meeting of the shareholders, may be taken without a meeting if a consent in writing, setting forth the action so taken, shall be signed by all of the shareholders entitled to vote with respect to the subject matter thereof.

Section 2.14 Notice of Shareholder Business and Nominations:

(a) Annual Meetings of Shareholders.

(1) Nominations of persons for election to the Board of Directors of the corporation and the proposal of business to be considered by the shareholders may be made at an annual meeting of shareholders only (i) pursuant to the corporation’s notice of meeting or any supplement to the corporation’s notice of meeting, (ii) by or at the direction of the Board of Directors or (iii) by any shareholder of the corporation who (A) was a shareholder of record of the corporation when the notice provided for in this Section 2.14 is delivered to the Secretary of the corporation, (B) is entitled to vote at the meeting and (C) complies with the notice procedures set forth in subparagraphs (2) and (3) of this Section 2.14(a).

The shareholder’s notice shall set forth the information required by Section 2.14(c).

(3) Notwithstanding anything in the second sentence of Section 2.14(a)(2) to the contrary, if the number of directors to be elected to the Board of Directors of the corporation at an annual meeting is increased and there is no public announcement 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 shareholder’s notice required by this Section 2.14 shall also be considered timely, but only with respect to nominees for any new positions created by the increase, if it is delivered to the Secretary at the principal executive offices of the corporation not later than ten (10) days following the day on which the public announcement is first made by the corporation.

(b) Special Meetings of Shareholders.

(1) The only business that may be conducted at a special meeting of shareholders is the business described in the corporation’s notice of meeting.

If a special meeting of shareholders is called to elect one or more directors to the Board of Directors, any shareholder entitled to vote in the election of directors may nominate a person or persons (as the case may be) for election to such position(s) as specified in the corporation’s notice of meeting, if the shareholder’s notice containing the information and as otherwise required by Section 2.14(b)(2) is delivered to the Secretary at the principal executive offices of the corporation not later than ten (10) days following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at the meeting. The public announcement of an adjournment or postponement of a special meeting shall not commence a new time period (or extend any time period) for the giving of a shareholder’s notice as described above.

(2) For nominations to be properly brought before a special meeting by a shareholder pursuant to clause (ii) of Section 2.14(b)(1), the shareholder’s notice must contain the information required by Section 2.14(c).

(c) Information Required in Shareholder Notice. A shareholder notice given pursuant to Section 2.14(a) or 2.14(b) shall contain the following information:

(1) the name and address of the shareholder, as they appear on the corporation’s books, and of the beneficial owner;

(2) the class and number of shares of capital stock of the corporation that are owned beneficially and of record by the shareholder and the beneficial owner;

(3) a representation that the shareholder is a holder of record of stock of the corporation entitled to vote at the special meeting and intends to appear in person or by proxy at the special meeting to propose such business or nomination;

(4) a representation as to whether the shareholder or the beneficial owner, if any, intends or is part of a group which intends to (a) deliver a proxy statement and/or form of proxy to holders of at least the percentage of the corporation’s outstanding capital stock required to approve or adopt the proposal or elect the nominee and/or (b) otherwise solicit proxies from shareholders in support of such proposal or nomination;

(5) any other information concerning the nominee that must be disclosed of nominees in proxy solicitations pursuant to Regulation 14A under the Securities Exchange Act of 1934 (the “Exchange Act”); and

(6) the executed consent of each nominee to serve as a director of the corporation if elected.

The corporation may require any proposed nominee to furnish any other information it reasonably requires to determine the eligibility of the proposed nominee to serve as a director.

(d) General.

(1) Only persons nominated in accordance with the procedures set forth in this Section 2.14 shall be eligible to be elected at an annual or special meeting of shareholders of the corporation to serve as directors and only such business shall be conducted at a meeting of shareholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 2.14. Except as otherwise provided by law, the chairman of the meeting shall have the power and duty to (i) determine whether a nomination or any business proposed to be brought before an annual or special meeting was made or proposed, as the case may be, in accordance with the procedures set forth in this Section 2.14 and (ii) if any proposed nomination or business is not in compliance with this Section 2.14 (including whether the shareholder or any beneficial owner on whose behalf the nomination or proposal is made solicits (or is part of a group which solicits), or fails to so solicit (as the case may be), proxies in support of such shareholder’s nominee or proposal in compliance with such shareholder’s representation as required by Section 2.14(c)(3)or (4)), to declare that such nomination shall be disregarded or that such proposed business shall not be transacted.

(2) For purposes of this Section 2.14, “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press, PR Newswire 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.

SECTION 3

Board of Directors

Section 3.1 General Powers: The business and affairs of the corporation shall be managed by its Board of Directors.

Section 3.2 Number, Tenure and Qualifications: The Board of Directors shall consist of not less than one (1) nor more than twelve (12) members. The number of directors will be fixed by the Board from time to time as provided in Article SIXTH of the Articles of Incorporation. The Board of Directors is authorized by the Articles of Incorporation to increase or decrease the size of the Board of Directors (within the range specified above) at any time by the affirmative vote of two-thirds of the directors then in office. Without the unanimous consent of the directors then in office, no more than two (2) additional directors shall be added to the Board of Directors in any 12-month period. The total number of Directors fixed pursuant to this Section 3.2 from time to time is referred to in these Bylaws as the “entire Board of Directors.”

The Board shall be divided into three classes: Class I Directors, Class II Directors and Class III Directors. Each such class of directors shall be nearly equal in number of directors as possible. Each director shall serve for a term ending at the third annual shareholders’ meeting following the annual meeting at which such director was elected, except as provided in Article SIXTH of the Articles of Incorporation. Notwithstanding the foregoing, each director shall serve until his or her successor shall have been elected and qualified or until his or her earlier death, resignation or removal.

At each annual election, the directors chosen to succeed those whose terms then expire shall be identified as being of the same class as the directors they succeed, unless, by reason of any intervening changes in the authorized number of directors, the Board of Directors shall designate one or more directorships whose term then expire as directorships of another class in order more nearly to achieve equality in the number of directors among the classes.

Directors need not be shareholders of the corporation. A director may resign at any time by filing his or her resignation with the Secretary of the corporation.

Section 3.3 Chairman of the Board: The Board of Directors will elect a Chairman of the Board of Directors from among its members. The Chairman of the Board of Directors shall, when present, preside at all meetings of the shareholders and of the Board of Directors. The Chairman of the Board of Directors shall perform such other duties as may be prescribed by these Bylaws or by the Board of Directors from time to time. At the Effective Time, as defined in the Agreement and Plan of Merger by and among the corporation, Host Acquisition Corporation and U.S. BioEnergy Corporation, dated as of November 29, 2007 (the “USBE Merger Agreement”), Gordon W. Ommen shall be elected by the Board of Directors to serve as the Non-Executive Chairman of the Board of Directors until the annual meeting of the shareholders in 2009, unless earlier removed in compliance with the next sentence hereof. Notwithstanding anything to the

contrary contained in these Bylaws, until the annual meeting of shareholders in 2009, the removal of Gordon W. Ommen as Non-Executive Chairman of the Board of Directors shall require the affirmative vote of not less than seventy-five percent (75%) of the entire Board of Directors. References in these Bylaws to the “Chairman of the Board” shall include the “Non-Executive Chairman of the Board”.

Section 3.4 Regular Meetings: A regular meeting of the Board of Directors shall be held without other notice than this Bylaw immediately after, and at the same place as, the annual meeting of shareholders. The Board of Directors may provide, by resolution, the time and place, either within or without the State of South Dakota, for the holding of additional regular meetings without other notice than such resolution.

Section 3.5 Special Meetings: Special meetings of the Board of Directors may be called by or at the request of the Chairman of the Board, the Chief Executive Officer, the President or any two (2) directors. The person or persons authorized to call special meetings of the Board of Directors may fix any place, either within or without the State of South Dakota, as the place for holding any special meeting of the Board of Directors called by them.

Section 3.6 Notice: Notice of any special meeting shall be given at least forty-eight (48) hours prior to the meeting by notice communicated in person, by telephone, telegraph, facsimile transmission or other form of wire or wireless communication, or by mail or private courier. If mailed, such notice shall be deemed effective when deposited in the United States mail addressed to the director at the director’s business address, with postage thereon prepaid. Whenever any notice is required to be given to any director of the corporation under the Articles of Incorporation, these Bylaws, or any provision of law, a waiver thereof in writing signed at any time, whether before or after the time of the meeting by the director entitled to notice, shall be deemed the equivalent of the giving of such notice. The attendance of a director at a meeting shall constitute a waiver of notice of such meeting, except where a director attends a meeting for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened. Unless otherwise required by the Articles of Incorporation, these Bylaws, or any provision of law, neither the business to be transacted at, nor the purpose of, any regular meeting of the Board of Directors need be specified in the notice or waiver of notice of such meeting.

Section 3.7 Quorum: A majority of the number of directors elected and who have qualified for their position shall constitute a quorum for the transaction of business at any meeting of the Board of Directors, but if less than a majority is present at a meeting, a majority of the directors present may adjourn the meeting from time to time without further notice.

Section 3.8 Manner of Acting: Except as otherwise provided by these Bylaws, the act of the majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors, unless the act of a greater number is required by law, or by the Articles of Incorporation or these Bylaws.

Section 3.9 Action Without A Meeting: Any action required or permitted by the Articles of Incorporation, these Bylaws or any provision of law to be taken by the Board of Directors at a meeting may be taken without a meeting if a consent in writing, setting forth the action so taken, shall be signed by all of the directors then in office.

Section 3.10 Removal: Directors may be removed only for “cause” as defined in Article SIXTH of the Articles of Incorporation. A director may be removed from office by affirmative vote taken at a special meeting of the shareholders called for the purpose. If less than the entire Board is to be removed, no one of the directors may be removed if the votes cast against his or her removal would be sufficient to elect him or her if then cumulatively voted at an election of the entire Board of Directors.

Section 3.11 Vacancies: Newly created directorships resulting from any increase in the number of directors and any vacancies on the Board of Directors resulting from death, resignation, removal or other cause shall be filled by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Board of Directors. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

When the Board fills a vacancy resulting from the death, resignation or removal of a director, the director chosen to fill that vacancy shall be of the same class as the director he or she succeeds, unless, by reason of any previous changes in the authorized number of directors, the Board shall designate the vacant directorship as a directorship of another class in order more nearly to achieve equality in the number of directors among the classes. The term of any director elected by the Board to fill a vacancy will expire at the next shareholders meeting at which directors are elected, despite the class such director has been elected to fill.

Notwithstanding the rule that the three classes shall be as nearly equal in number of directors as possible, upon any change in the authorized number of directors, each director then continuing to serve as such will nevertheless continue as a director of the class of which he or she is a member, until the expiration of his or her current term or his or her earlier death, resignation or removal.

Section 3.12 Compensation: The Board of Directors by affirmative vote of a majority of the directors then in office, and irrespective of any personal interest of any of its members, may provide for the payment of the expenses of the directors, if any, of attendance at each meeting at the Board of Directors, and may establish reasonable compensation of all directors for services to the corporation as directors, officers or otherwise. The Board of Directors also shall have authority to provide for reasonable pensions, disability or death benefits, and other benefits or payments, to directors, officers and employees and to their estates, families, dependents or beneficiaries on account of prior service rendered by such directors, officers and employees to the corporation. No such payment shall preclude any director from serving the corporation in any other capacity and receiving compensation therefor.

Section 3.13 Presumption of Assent: A director of the corporation who is present at a meeting of the Board of Directors at which action on any corporate matter is taken shall be presumed to have assented to the action taken unless his or her dissent shall be entered in the minutes of the meeting or unless he or she shall file his or her written dissent to such action with the person acting as the secretary of the meeting before the adjournment therefor or shall forward such dissent by registered mail to the Secretary of the corporation immediately after adjournment of the meeting. Such right to dissent shall not apply to a director who voted in favor of such action.

Section 3.14 Committees: The Board of Directors by resolution adopted by the affirmative vote of a majority of the entire Board of Directors may designate an Executive Committee and one or more other committees, each committee to consist of two (2) or more directors elected by the Board of Directors. The Executive Committee shall have and may exercise, when the Board of Directors is not in session, the powers of the Board of Directors in the management of the business and affairs of the corporation, except action in respect of any matter which requires a unanimous or super-majority vote of the directors pursuant to these Bylaws, including, without limitation, as set forth in Sections 3.2, 3.3 or 4.11 of these Bylaws, dividends to shareholders, election of officers, amending the Articles of Incorporation, amending these Bylaws, adopting a plan of merger or consolidation, recommending to the shareholders the sale, lease, exchange or other disposition of all or substantially all of the property and assets of the corporation otherwise than in the usual or regular course of its business, recommending to the shareholders a voluntary dissolution of the corporation or a revocation thereof, or the filling of vacancies in the Board of Directors or committees created pursuant to this Section 3.14. The other committees, if any, shall have and may exercise such powers as may be provided in the resolution of the Board of Directors designating such committee and consistent with these Bylaws, as such resolution may from time to time be amended and supplemented. The Board of Directors may elect one or more of its members as alternate members of any such committee who may take the place of any absent member or members at any meeting of such committee, upon request by the Chairman of the Board, the Chief Executive Officer, the President or upon request by the chairman of such meeting. Each such committee shall fix its own rules governing the conduct of its activities and shall make such reports to the Board of Directors of its activities as the Board of Directors may request.

Indemnification

Section 5.1 Third Party Actions: The corporation may indemnify to the fullest extent not prohibited by law any person who is made, or threatened to be made, a party to any action, suit or proceeding, whether civil, criminal, administrative, arbitrative, investigative or otherwise, including all appeals, by reason of the fact that he or she (hereinafter an “Indemnitee”) is or was a director, officer, employee or agent of the corporation, or a fiduciary within the meaning of the Employee Retirement Income Security Act of 1974 with respect to any employee benefit plan of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent, or as a fiduciary of an employee benefit plan, of another corporation, limited liability company, partnership, joint venture, trust or other enterprise, against all expenses (including attorneys’ fees), judgments, decrees, fines, penalties, and amounts paid in settlement actually and reasonably incurred by the Indemnitee in connection with such action, suit or proceeding; provided, however, that the corporation shall not indemnify a director or officer for liability for receipt of a financial benefit to which the director or officer is not entitled, an intentional infliction of harm on the corporation or its shareholders, an unlawful distribution, or an intentional violation of criminal law.

connection with the defense or settlement of such action or suit; provided, however, that the corporation may indemnify a director or officer in connection with a suit or proceeding by or in the right of the corporation for reasonable expenses incurred in connection with the suit or proceeding only if it is determined that the director or officer has acted in good faith and (i) in the case of conduct in an official capacity, reasonably believed that the conduct was in the best interests of the corporation, (ii) in all other cases, reasonably believed that the conduct was at least not opposed to the best interests of the corporation, and (iii) in the case of any criminal proceeding, had no reasonable cause to believe the conduct was unlawful.

Section 5.5 Advances of Expenses: Expenses of each person indemnified hereunder (including attorneys’ fees) incurred in defending a civil, criminal, administrative, arbitrative or investigative action, suit, or proceeding (including all appeals) may be paid or reimbursed by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of (i) a written affirmation of the person’s good faith belief that he or she has met any relevant standard of conduct described in Section 5.1 or Section 5.2 or that the proceeding involves conduct for which liability has been eliminated under a provision of the Articles of Incorporation and (ii) a written undertaking by the director, officer, employee, or agent to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the corporation.

Section 5.6 Nonexclusiveness: The indemnification provided by this Section 5 shall not be deemed exclusive of any other rights not prohibited by law to which those seeking indemnification may be entitled as a matter of law or under the

Articles of Incorporation, these Bylaws, any agreement, vote of shareholders, any insurance purchased by the corporation, or otherwise, both as to action in the Indemnitee’s official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.
