ARTICLE II : MEETINGS OF SHAREHOLDERS

Section 2.01 Place of Meetings. All meetings of shareholders shall be held at such place, if any, within or outside the State of Iowa, including by means of remote communications, which may be designated by the Board of Directors.

Section 2.02 Remote Communications. The Board of Directors, acting in its sole discretion, may establish guidelines and procedures in accordance with applicable provisions of the Iowa Business Corporation Act (the “IBCA”) and any other applicable law for the participation of shareholders by means of remote communications, and may determine that any meeting of shareholders will not be held at any place but will be held solely by means of remote communications. Shareholders and proxy holders complying with such procedures and guidelines and otherwise entitled to vote at a meeting of shareholders shall be deemed present in person and entitled to vote at a meeting of shareholders, whether such meeting is to be held at a designated place or solely by means of remote communications.

Section 2.03 Annual Meetings. The annual meetings of shareholders shall be held on such date and at such time as the Board of Directors shall determine. At such meetings, directors shall be elected and any other business may be transacted which is within the powers of the shareholders. If the election of directors shall not be accomplished at the annual meeting of shareholders, including any adjournment or postponement thereof, the Board of Directors shall cause such election to be held at a special meeting of shareholders called for that purpose as soon thereafter as is convenient.  Any previously scheduled annual meeting of the shareholders may be postponed by resolution of the Board of Directors upon prior notice or public disclosure given on or prior to the date previously scheduled for such annual meeting of shareholders. The annual meeting of shareholders may be postponed by the Corporation to such time and place, if any, as is specified in the notice of postponement of such meeting.

Section 2.04 Special Meetings. 

(a) Special meetings of the shareholders may be called, for any purpose or purposes, by (i) the Chairman of the Board, (ii) the Chief Executive Officer, (iii) the President, (iv) the Board of Directors or a committee thereof, or (v) one or more shareholders of record that, at the time a request is delivered, collectively Own (as defined below) at least 20% of all of the outstanding shares entitled to vote at the proposed special meeting, and shall be held at such place, if any, on such date, and at such time as the Board of Directors shall fix.

(b) If a special meeting is properly called by any person or persons other than the Board of Directors, the request shall be in writing, specifying the general nature of the business proposed to be transacted, and shall be delivered personally or sent by certified or registered mail, return receipt requested, to the Chairman of the Board, the Chief Executive Officer, or the Secretary. Unless otherwise determined by the Board of Directors, no business may be transacted at such special meeting other than as specified in such notice. The Board of Directors shall determine the time and place of such special meeting, which shall be held not less than 35 nor more than 120 days after the date of the receipt of the request. Upon determination of the time and place of the meeting, the officer receiving the request shall cause notice to be given to the shareholders entitled to vote in accordance with the provisions of Section 2.05. Nothing contained in this Section 2.04(b) shall be construed as limiting, fixing, or affecting the time when a meeting of shareholders called by action of the Board of Directors may be held.

(c) Nominations of persons for election to the Board of Directors may be made at a special meeting of shareholders at which directors are to be elected pursuant to the Corporation’s notice of meeting (i) by or at the direction of the Board of Directors or (ii) by any shareholder of the Corporation who is a shareholder of record at the time of giving notice provided for in these Bylaws of the Corporation (as may be amended or amended and restated from time to time, these “Bylaws”) who shall be entitled to vote at the meeting and who complies with the notice procedures set forth in this Section 2.04. In the event the Corporation calls a special meeting of shareholders for the purpose of electing one or more directors to the Board of Directors, any such shareholder 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 required by Section 2.11 (which shall also be required by this Section 2.04) of these Bylaws shall be received by the Secretary at the principal executive offices of the Corporation not earlier than the close of business on the 120th day prior to the date of such special meeting and not later than the close of business on the later of the 90th day prior to the date of such meeting or the 10th day following the day on which a 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 such meeting. In no event shall the public announcement of an adjournment or postponement of a special meeting commence a new time period (or extend any time period) for the giving of a shareholder’s notice as described above.

(d) Any previously scheduled special meeting of the shareholders may be postponed by resolution of the Board of Directors upon prior notice or public disclosure given on or prior to the date previously scheduled for such special meeting of shareholders. The special meeting of shareholders may be postponed by the Corporation to such time and place, if any, as is specified in the notice of postponement of such meeting.

Section 2.05 Notice of Meetings. Written notice of each annual meeting shall be given to each shareholder entitled to vote, either personally or by mail or other means of written communication, or by electronic means where permissible, charges prepaid, addressed to such shareholder at such shareholder’s address appearing on the books and records of the Corporation or given by shareholder to the Corporation for the purpose of notice. All such notices shall be sent to each shareholder entitled thereto not less than 10 nor more than 60 days before each annual meeting, and shall specify (a) the place, if any, the date and the time of such meeting, (b) the means of remote communications, if any, by which shareholders and proxy holders may be deemed to be present in person and vote at such meeting, and (c) such other matters, if any, as may be expressly required by statute. If mailed, such notice shall be deemed to be given when deposited in the United States mail, postage prepaid, directed to the shareholder at his or her address as it appears on the books and records of the Corporation.

Section 2.06 Adjourned Meetings and Notice Thereof. Any shareholders’ meeting, annual or special, whether or not a quorum is present, may be adjourned or postponed from time to time by either the Chairman of the Board or the vote of a majority of the shares represented at the meeting, the holders of which are either present in person or represented by proxy thereat, but in the absence of a quorum, no other business may be transacted at such meeting.

Section 2.07 Voting; Proxies. Each shareholder entitled to vote at any meeting of shareholders shall be entitled to one vote for each share of stock held by him or her, which has voting power upon the matter in question. Each shareholder entitled to vote at a meeting of shareholders may authorize another person or persons to act for him or her by proxy, but no such proxy shall be voted or acted upon after eleven months from its date, unless the proxy provides for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A shareholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with the Secretary. In any election of directors, if a quorum is present, directors shall be elected by a “majority of votes cast” (as defined herein), unless the election is contested, in which case directors shall be elected by a plurality of the votes cast. An election shall be contested if, as determined by the Board of Directors, the number of nominees exceeds the number of directors to be elected. For the purposes of this Section 2.07, a “majority of votes cast”  shall mean that the votes cast “for” a nominee’s election exceeds the votes cast “against” that nominee.  The following shall not be deemed votes cast “against” a nominee: (a) a share whose ballot or proxy is marked as abstain; (b) a share otherwise present at the meeting but for which there is an abstention; and (c) a share otherwise present at the meeting as to which a shareholder gives no authority or direction. Any incumbent director who is nominated for election and fails to receive the required vote for reelection shall promptly deliver to the Board of Directors an irrevocable offer to resign from the Board of Directors. The Board of Directors will consider such director’s offer to resign, taking into consideration any such factors that the Board of Directors deems

relevant in deciding whether to accept such director’s resignation, including any recommendation of the nominating and governance committee. Any director whose offer to resign is under consideration may not participate in any deliberation or vote of the Board of Directors (or any committee thereof) regarding such offer, but such director may participate in the deliberation or vote of any other business transacted by the Board of Directors (or any committee thereof). Within 90 days after the date of certification of the election results, the Board of Directors will determine whether to accept or reject such director’s offer to resign. Notwithstanding the foregoing, in the event that no nominee for director receives the vote required pursuant to this Section 2.07, any and all directors may participate in the Board of Directors’ deliberation and vote regarding the directors’ offers to resign. Any other action shall be authorized by an affirmative majority of the outstanding shares present in person or represented by proxy and entitled to vote, unless the question is one upon which by express provision of the Articles of Incorporation, these Bylaws or the IBCA a different vote is required, in which case such express provision shall govern and control the decision of such question.

Section 2.08 Filing Date for Determination of Shareholders of Record. In order that the Corporation may determine the shareholders entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof, or to express consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix, in advance, a record date, which shall not be more than 60 nor less than 10 days before the date of such meeting, nor more than 60 days prior to any other action. If no record date is fixed: (a) the record date for determining shareholders entitled to notice of or to vote at a meeting of shareholders 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; (b) the record date for determining shareholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto. A determination of shareholders of record entitled to notice of or to vote at a meeting of shareholders shall apply to any adjournment or postponement of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned or postponed meeting.

Section 2.09 List of Shareholders Entitled to Vote. The Secretary shall prepare and make, at least 10 days before every meeting of shareholders, a complete list of the shareholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each shareholder and the number of shares registered in the name of each shareholder. Nothing contained in this Section 2.09 shall require the Corporation to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any shareholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least 10 days prior to the meeting, either (a) on a reasonably accessible electronic network;  provided that the information required to gain access to such list is provided with the notice of the meeting, or (b) during ordinary business hours, at the principal place of business of the Corporation. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to shareholders of the Corporation. If the meeting is to be held in person, then a list of shareholders entitled to vote at the meeting shall be produced and kept at the time and place of the meeting during the whole time thereof and may be inspected by any shareholder who is present. If

the meeting is to be held solely by means of remote communications, then such list shall also be open to the examination of any shareholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided within the notice of the meeting. The stock ledger shall be the only evidence as to who are the shareholders entitled to examine the stock ledger, the list of shareholders referred to in this section or the books of the Corporation, or to vote in person or by proxy it any meeting of shareholders.

Section 2.10 Quorum. The presence in person or by proxy of persons entitled to vote a majority of the votes entitled to be cast by each separate class or voting group specified in the Corporation’s Articles of Incorporation, as the same may be amended or supplemented from time to time, at any meeting shall constitute a quorum for the transaction of business. The shareholders present at a duly called or held meeting at which a quorum is present may continue to do business until adjournment or postponement, notwithstanding the withdrawal of enough shareholders to leave less than a quorum.

Section 2.11 Business Conducted at Meetings of Shareholders; Shareholder Proposals. To be properly brought before any meeting of shareholders, nominations of persons for election to the Board of Directors and proposals of business other than nominations to be considered by the shareholders must be (A) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors, (B) otherwise properly brought before the meeting by or at the direction of the Board of Directors or (C) otherwise properly brought before the meeting by a shareholder who (i) was a shareholder of record at the time of giving notice for the meeting, at the time the notice provided for in this Section 2.11 is timely delivered to the principal executive offices of the Corporation, and at the time of the meeting, (ii) timely complies with the notice procedures of this Section 2.11 and (iii) is entitled to vote at the meeting. In addition, for business to be properly brought before any meeting by a shareholder, such business must be a proper matter for shareholder action pursuant to these Bylaws and applicable law.  For the avoidance of doubt, the foregoing clause (C) shall be the exclusive means for a shareholder to make nominations (except for nominations made in compliance with Section 2.12) or propose business at any meeting of shareholders (other than a proposal included in the Corporation’s proxy statement pursuant to and in compliance with Rule 14a-8 under the Exchange Act). To be timely, a shareholder’s notice must be delivered to, or mailed and received at, the principal executive offices of the Corporation not less than 90 days nor more than 120 days prior to the one-year anniversary of the date of the preceding year’s annual meeting; provided, however, that in the event of a special meeting or if the date of the annual meeting is advanced by more than 30 days or delayed by more than 30 days from the anniversary of the previous year’s annual meeting, to be timely, a shareholder’s notice must be received by the Corporation not earlier than the close of business on the 90th day prior to such meeting and not later than the close of business on the later of the 60th day prior to such meeting or the 10th day following the day on which public disclosure of the date of such meeting is first made.  In no event shall any adjournment or postponement of a meeting or the announcement thereof commence a new time period for the giving of a shareholder’s notice as described in this Section 2.11.  Such shareholder’s notice shall set forth the following:

(a) As to each person whom the Proposing Person (as defined below) proposes to nominate for election or reelection as a director, (i) all information relating to such person that is required to be disclosed in solicitations of proxies for elections of directors, or is otherwise

(b) As to any other business that the Proposing Person proposes to bring before the meeting,  a brief description of the business desired to be brought and the reasons for conducting such business at the meeting and any material interest in such business of such shareholder and the beneficial owner, if any, on whose behalf the proposal is made; and

(c) As to the Proposing Person, if any, on whose behalf the nomination or proposal is made (i) the name and address of such Proposing Person,  if not a beneficial owner, as they appear on the Corporation’s books;  (ii) the class and number of shares of the Corporation which are held of record or are beneficially Owned, directly or indirectly, by the Proposing Person and any Derivative Instrument (as defined below) and by any other shareholders known by such Proposing Person to be supporting such proposal;  (iii) whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of such Proposing Person or nominee with respect to any securities of the Corporation, and a description of any other agreement, arrangement or understanding (including any short position or any borrowing or lending of shares), the effect or intent of which is to mitigate loss to, or to manage the risk or benefit from share price changes for, or to increase or decrease the voting power of, such Proposing

Person or nominee with respect to any securities of the Corporation;  (iv) any proxy, contract, arrangement, understanding or relationship pursuant to which the Proposing Person or nominee has a right to vote any shares of any security of the Corporation; (v) any rights to dividends on the shares of the Corporation beneficially Owned by the Proposing Person that are separated or separable from the underlying shares of the Corporation;  (vi) any performance-related fees (other than asset-based fees) that the Proposing Person or the nominee is entitled to, based on any increase or decrease in the value of shares of the Corporation or Derivative Instruments, if any, as of the date of such notice, if any, including without limitation any such interests held by members of such Proposing Person’s immediate family sharing in the same household;  (vii) any material interest of the Proposing Person in such business; and (viii) a statement whether such Proposing Person will deliver a proxy statement and form of proxy to holders of at least the percentage of the Corporation’s voting shares required under applicable law to carry the proposal or nomination.  In addition, to be in proper written form, the Proposing Person’s notice to the Secretary must be supplemented not later than 10 days following the record date for notice of the meeting to disclose the information contained in clauses (ii) through (vi) above as of the record date for notice of the meeting.  For purposes of this Section 2.11, a “Derivative Instrument” shall mean any option, warrant, convertible security, stock appreciation right or similar right with an exercise or conversion privilege or a settlement payment or mechanism at a price related to any class or series of shares of the Corporation or with a value derived in whole or in part from the value of any class or series of capital stock of the Corporation or otherwise. For purposes of this Section 2.11, the term “Proposing Person” shall mean (A) the shareholder providing the notice of nomination or any other business proposed to be brought before the meeting of shareholders, (B) the beneficial owner or beneficial owners, if different, on whose behalf the notice of nomination or any other business proposed to be brought before the meeting is made, (C) any affiliate or associate (each within the meaning of Rule 12b-2 under the Exchange Act for purposes of these Bylaws) of such shareholder or beneficial owners and, if such shareholder or beneficial owner is an entity, any director, executive, managing member or control person of such entity, and (D) any other person with whom such shareholder or beneficial owner (or any of their respective affiliates or associates) is acting in concert.

Section 2.12 Shareholder Nominations Included in the Corporation’s Proxy Materials. 

(a) Definitions. For purposes of this Section 2.12, the following terms shall have the meanings set forth below, except as otherwise provided herein.

(b) Inclusion of Nominee in Proxy Statement. Subject to the provisions of this Section 2.12, if expressly requested in a Qualified Nomination Notice delivered by a Nominating

Shareholder, the Corporation shall include in its proxy statement for any annual meeting of the shareholders:

(i) the name of the Nominee, which shall also be included on the Corporation’s form of proxy and ballot;

(ii) disclosures about the Nominee and Nominating Shareholder required under the rules of the SEC or other applicable law to be included in the proxy statement;

(iii) any statement included by the Nominating Shareholder in the Qualified Nomination Notice for inclusion in the proxy statement in support of the Nominee’s election to the Board of Directors (subject, without limitation, to Section 2.12(e)), if such statement does not exceed 500 words, is delivered at the same time as the Qualified Nomination Notice, and fully complies with Section 14 of the Exchange Act, and the rules and regulations thereunder, including Rule 14a-9; and

(iv) any other information that the Corporation or the Board of Directors determines, in its discretion, to include in the proxy statement relating to the nomination of the Nominee, including, without limitation, any statement in opposition to the nomination and any of the information provided pursuant to this Section 2.12.

(c) Maximum Number of Nominees.

(i) The Corporation shall not be required to include in the proxy statement for an annual meeting of the shareholders more Nominees than the Maximum Number for such annual meeting. The Maximum Number for a particular annual meeting of the shareholders shall be reduced by: (A) Nominees who are subsequently withdrawn or that the Board of Directors itself decides to nominate for election at such annual meeting, (B) Nominees who cease to satisfy, or Nominees of Nominating Shareholders that cease to satisfy, the eligibility requirements in this Section 2.12, and (C) the number of incumbent directors who were Nominees with respect to any of the preceding two annual meetings of the shareholders and whose reelection at the upcoming annual meeting of the shareholders is being recommended by the Board of Directors. If one or more vacancies for any reason occurs on the Board of Directors after the deadline set forth in Section 2.12(e), but before the date of the annual meeting of the shareholders, and the Board of Directors resolves to reduce the size of the Board of Directors in connection therewith, the Maximum Number shall be calculated based on the number of directors in office as so reduced.

(ii) If the number of Nominees pursuant to this Section 2.12 for any annual meeting of the shareholders exceeds the Maximum Number then, promptly upon notice from the Corporation, each Nominating Shareholder will select one Nominee for inclusion in the proxy statement until the Maximum Number is reached, going in order of the amount (largest to smallest) of the Ownership position as disclosed in each Nominating Shareholder’s Qualified Nomination Notice, with the process repeated if the Maximum Number is not reached after each Nominating Shareholder has selected one Nominee. If, after the deadline for submitting a Qualified Nomination Notice as set forth in Section 2.12(e), a Nominating Shareholder becomes ineligible or withdraws its nomination, or a Nominee becomes unwilling to serve on the Board of Directors,

whether before or after the delivery of the definitive proxy statement, then the nomination shall be disregarded, and the Corporation (A) shall not be required to include in its proxy statement or on any ballot or form of proxy the disregarded Nominee or any successor or replacement Nominee proposed by the Nominating Shareholder or by any other Nominating Shareholder, and (B) may otherwise communicate to its shareholders, including, without limitation, by amending or supplementing its proxy statement or ballot or form of proxy, that the Nominee will not be included as a Nominee in the proxy statement or on any ballot or form of proxy and will not be voted on at the annual meeting of the shareholders.

(d) Eligibility of Nominating Shareholder. 

(i) An Eligible Holder or group of up to 20 Eligible Holders may submit a nomination in accordance with this Section 2.12 only if the person or group (in the aggregate) has continuously Owned at least the Minimum Number of shares of the common stock of the Corporation (as adjusted for any stock splits, stock dividends, or similar events) throughout the three-year period preceding, including the date of submission of, the Qualified Nomination Notice, and continues to Own at least the Minimum Number through the date of such annual meeting of the shareholders. A group of funds under common management and investment control shall be treated as one Eligible Holder if such Eligible Holder shall provide, together with the Qualified Nomination Notice, documentation reasonably satisfactory to the Corporation that demonstrates that the funds are under common management and investment control. For the avoidance of doubt, in the event of a nomination by a group of Eligible Holders, any and all requirements and obligations for an individual Eligible Holder that are set forth in this Section 2.12, including the minimum holding period, shall apply to each member of such group; provided, however, that the Minimum Number shall apply to the Ownership of the group in the aggregate. If any shareholder withdraws from a group of Eligible Holders acting together as a Nominating Shareholder at any time prior to the annual meeting of the shareholders, the group of Eligible Holders shall only be treated as Owning the shares held by the remaining members of the group.

(ii) For purposes of Section 2.04 and this Section 2.12,  a shareholder or beneficial owner shall be deemed to  “Own” only those outstanding shares of common stock of the Corporation as to which such person possesses both:  (A) the full voting and investment rights pertaining to the shares; and (B) the full economic interest in (including the opportunity for profit and risk of loss on) such shares. The number of shares calculated in accordance with clauses (A) and (B) shall not include any shares: (1) purchased or sold by such person or any of its affiliates in any transaction that has not been settled or closed, (2) sold short by such person, (3) borrowed by such person or any of its affiliates for any purpose or purchased by such person or any of its affiliates pursuant to an agreement to resell or subject to any other obligation to resell to another person, or (4) subject to any option, warrant, forward contract, swap, contract of sale, other derivative or similar agreement entered into by such person or any of its affiliates, whether any such instrument or agreement is to be settled with shares or with cash based on the notional amount or value of outstanding shares of common stock of the Corporation, in any such case which instrument or agreement has, or is intended to have, the purpose or effect of: (x) reducing in any manner, to any extent or at any time in the future, such person’s or any of its affiliates’ full right to vote or direct the voting of any such shares, and/or (y) hedging, offsetting, or altering to any degree, gain or loss arising from the full economic ownership of such shares by such person or any of its affiliates. A  shareholder or beneficial owner shall  “Own” shares held in the name of a

Nominee or other intermediary, so long as such person retains the right to instruct how the shares are voted with respect to the election of directors and possesses the full economic interest (including the opportunity for profit and risk of loss on) in the shares. Such person’s Ownership of shares shall be deemed to continue during any period in which such person has delegated any voting power by means of a proxy, power of attorney, or other similar instrument or arrangement that is revocable at any time by such person. The terms “Owned,” “Owning,”  “Ownership”  and other variations of the word “Own” shall have correlative meanings. Whether outstanding shares of common stock of the Corporation are “Owned” for these purposes shall be determined by the Board of Directors.

(iii) No person shall be permitted to be in more than one group constituting a Nominating Shareholder, and if any person appears as a member of more than one group, it shall be deemed to be a member of the group that has the largest ownership position as reflected in the Qualified Nomination Notice.

(e) Qualified Nomination Notice. To nominate a Nominee, the Nominating Shareholder must, no earlier than 150 days and no later than 120 days before the anniversary of the date that the Corporation delivered its proxy statement for the prior year’s annual meeting of the shareholders, submit to the Secretary at the principal executive office of the Corporation all of the following information and documents (collectively, the “Qualified Nomination Notice”), and in no event will the public announcement of an adjournment of the annual meeting of shareholders commence a new time period for the giving of the Qualified Nomination Notice as provided above; provided, however, that if (and only if) the annual meeting of the shareholders is not scheduled to be held within a period that commences 30 days before the anniversary date of the prior year’s annual meeting of shareholders and ends 30 days after such anniversary date (an annual meeting of the shareholders date outside such period being referred to herein as an “Other Meeting Date”), the Qualified Nomination Notice shall be given in the manner provided herein by the later of the close of business on the date that is 180 days prior to such Other Meeting Date or the tenth day following the date such Other Meeting Date is first publicly announced or disclosed:

ARTICLE VII : INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 7.01 Indemnification.  

(a) Each person who was or is made a party or is threatened to be made a party or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer, of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a

director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the IBCA, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that, except as provided in Section 7.01(b) hereof, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board of Directors.

(b) The right to indemnification conferred in this Section 7.01 shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, if the IBCA requires, the payment of such expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Section 7.01 or otherwise. The Corporation may, by action of its Board of Directors, provide indemnification to employees and agents of the Corporation with the same scope and effect as the foregoing indemnification of directors and officers.

Section 7.02 Right to Sue. If a claim under Section 7.01 is not paid in full by the Corporation within 30 days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the IBCA for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its shareholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the IBCA, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its shareholders) that the claimant has not met such applicable standard or conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard or conduct.

Section 7.03 Non-Exclusivity of Rights. The rights conferred on any person in Section 7.01 and Section 7.02 shall not be exclusive of any other right which such persons may

have or hereafter acquire under any statute, provision of the Articles of Incorporation, these Bylaws, agreement, vote of shareholders or disinterested directors, or otherwise.

Section 7.04 Insurance. The Corporation may maintain insurance to the extent reasonably available at commercially reasonable rates (in the judgment of the Board of Directors), at its expense, to protect itself and any such director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the IBCA.

Section 7.05 Effect or Amendment. Any amendment, repeal or modification of any provision of this Article VII which reduces or eliminates the rights of any director, officer, employee or agent under this Article VII shall apply only to acts, omissions, events or occurrences that take place after the effectiveness of such amendment, repeal or modification, regardless of when any action, suit or proceeding is commenced, and shall not affect the rights of any director, officer, employee or agent with respect to acts, omissions, events or occurrences that take place prior to the effectiveness of such amendment, repeal or modification.

Neither the business to be transacted at, nor the purpose of any regular or special meeting of the shareholders, directors, or members of a committee of directors, need be specified in any written waiver of notice.

Section 8.04 Interested Directors.

Any director of the Corporation who is so interested, or who is also a director, officer, trustee, employee or shareholder of such other corporate or association or a member of such partnership which is so interested, may be counted in determining the existence of a quorum at any meeting of the Board of Directors which shall authorize any such contract or transaction, and may vote thereat to authorize any such contract or transaction, with like force and, affect as if he or she were not such director, officer, trustee, employee or shareholder of such other corporation or association or not so interested or a member of a partnership so interested; provided that in case

a director, or a partnership, corporation or association of which a director is a member, officer, director, trustee or employee is so interested, such fact shall be disclosed or shall have been known to the Board of Directors or a majority thereof. This paragraph shall not be construed to invalidate any such contract or transaction which would otherwise be valid under the common and statutory law applicable thereto.

Section 8.05 Form of Records. Any records maintained by the Corporation in the regular course of its business, including its stock ledger, books of account, and minute books, may be kept on, or be in the form of, magnetic media, photographs, microphotographs, or any other information storage device;  provided that the records so kept can be converted into clearly legible form within a reasonable time.  The Corporation shall so convert any records so kept upon the request of any person entitled to inspect the same.
