Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On and effective May 21, 2012, the Board of Directors adopted amendments to the bylaws of the Company (the “Bylaws”). The following is a summary of the amendments, which is qualified in its entirety by reference to the amended form of the Bylaws filed as Exhibit 3.1 hereto.

The Board of Directors adopted a new Article I, Section 7, Notice of Stockholder Business and Nominations, which relates to advance notice requirements for stockholder proposals and nominations submitted at the Company’s annual and special meetings of stockholders. New Article I, Section 7 establishes disclosure requirements and other procedures applicable to stockholders intending to bring proposals and nominations before a meeting of stockholders, including informational requirements relating to the stockholder making the proposal or nomination (and the beneficial owner, if any, on whose behalf the proposal or nomination is being made), the proposal, if any, to be brought before the meeting, and the nominee, if any, submitted for election to our Board. New Article I, Section 7 also establishes a time period in which notice must be delivered to the Company and gives the chairman of the meeting the authority to determine whether such proposal or nomination was properly brought before the meeting. Generally, a stockholder must deliver his notice of any proposal or nomination that such stockholder intends to bring before an annual meeting of stockholders no later than the close of business on the 90th day, nor earlier than the close of business on the 120th day, prior to the first anniversary of the preceding year’s annual meeting; provided that, if the date of the annual meeting is more than 30 days before or more than 70 days after such anniversary date, notice by the stockholder must be delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made by the Company. Additionally, new Article I, Section 7 requires that the stockholder making the proposal or nomination (or a qualified representative of the stockholder) appear at the meeting to present the proposal or nomination.

Item 7.01 Regulation FD Disclosure.

On May 22, 2012, the Company held its 2012 annual meeting of stockholders. A copy of the presentation slides for the 2012 annual meeting of stockholders is furnished herewith as Exhibit 99.1 to this Report.

The information in this Item 7.01, including Exhibit 99.1, will not be treated as filed for the purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section. This information will not be incorporated by reference into a filing under the Securities Act of 1933, or into another filing under the Exchange Act, unless that filing expressly refers to specific information in this Report. The furnishing of the information in this Item 7.01 is not intended to, and does not, constitute a representation that such furnishing is required by Regulation FD or that the information in this Item 7.01 is material information that is not otherwise publicly available.

In the foregoing presentation, the Company utilized financial measures and terms not calculated in accordance with generally accepted accounting principles in the United States (“GAAP”) in order to provide stockholders with an alternative method for assessing its operating results in a manner that enables stockholders to more thoroughly evaluate its current performance as compared to past performance. The Company also believes these non-GAAP measures provide stockholders with a more informed baseline for modeling its future financial performance. The Company’s management uses these non-GAAP measures for the same purpose. The Company believes that its stockholders should have access to, and that it is obligated to provide, the same set of tools that it uses in analyzing its results. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. See Exhibit 99.1 to the Company’s Form 8-K, filed on May 8, 2012, for definitions of the non-GAAP financial measures, together with an explanation of why management uses these measures and why management believes that these non-GAAP financial measures are useful to stockholders and tables that reconcile the non-GAAP financial measures utilized to GAAP financial measures.

Cautionary Information Regarding Forward-Looking Statements

Except for the historical and factual information contained in the accompanying slides attached as Exhibit 99.1 to this Report, the matters set forth therein are forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially, including, but are not limited to, such factors as may be detailed from time to time in the Company’s filings with the United States Securities and Exchange Commission. You should not place undue reliance on these forward-looking statements, which speak only as of the date of the presentation slides. The Company undertakes no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise.

ARTICLE I

MEETINGS OF STOCKHOLDERS

Section 1. Annual Meetings. Annual meetings of stockholders shall be held on a date (other than a legal holiday), which shall be designated by the Board of Directors. At such meetings Directors shall be elected, reports of the affairs of the corporation shall be considered and any other business may be transacted which is within the power of the stockholders.

Section 2. Special Meetings. Special meetings of the stockholders may be called at any time by the President of the corporation or by a majority of the Board of Directors and shall be called by the President or Secretary at the written request of stockholders entitled to cast a majority of the votes which all stockholders are entitled to cast at the particular meeting.

Section 3. Place of Meetings. Each annual or special meeting of stockholders shall be held at such time and place within or without the State of Delaware as shall be so designated by the Board of Directors.

Section 4. Notice of Stockholders’ Meetings. The notice of all meetings of stockholders shall be in writing and shall state the place, data and hour of the meeting. The notice of an annual meeting shall state that the meeting is called for the election of the Directors to be elected at such meeting and for the transaction of such other business

-1-

as is stated in the notice or shall properly come before the meeting. The notice of a special meeting shall state the purpose or purposes for which the meeting is called and the business to be transacted at the meeting.

A copy of the notice of each meeting of stockholders shall be given personally or by mail not less than ten (10) days nor more than (60) days before the date of the meeting to each stockholder entitled to vote at such meeting at his record address or at such other address as he may have furnished to the company for the purpose of notice.

The holders of a majority of the stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders for the transaction of business except as otherwise provided by statute or by the certificate of incorporation. If, however, such quorum shall not be present or represented at any meeting of the stockholders, the stockholders entitled to vote thereat, present in person or represented by proxy, shall have power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present or represented. 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. If the adjournment is for more than thirty (30) days, or if after adjournment a new record date is fixed for the adjourned meeting, a notice of the adjournment shall be given to each stockholder of record entitled to vote at the meeting.

When a quorum is present at any meeting, the vote of the holders of a majority of the stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, unless the question is one upon which by express provision of the statutes or of the certificate of incorporation, a different vote is required, in which case such express provision shall govern and control the decision of such question.

-2-

Section 5. Voting. Every stockholder entitled to vote at any election for Directors shall have the right to cumulate his votes and give one candidate a number of votes equal to the number of Directors to be elected multiplied by the number of votes to which his shares are entitled, or to distribute his votes on the same principle among as many candidates and in such manner as he shall desire. The candidates receiving the highest number of votes up to the number of Directors to be elected shall be declared elected. Whenever any corporate action other than the election of Directors is to be taken by vote of the stockholders it shall, except as otherwise required by law or by the Certificate of Incorporation, be authorized by a majority of the votes cast at a meeting of stockholders by the holders of shares entitled to vote thereon.

Every person entitled to vote shall have the right to do so either in person or by one or more agents authorized by written proxy executed by such person or his duly authorized agent and filed with the Secretary of the corporation. Telegraphed or cabled proxies shall be valid.

Where a form of proxy issued by the Company’s management provides that the proxy holders are authorized, in their discretion, to vote upon such other business as may properly come before the meeting, such authorization shall be deemed to include authority to appoint a substitute nominee or nominees to the slate of management nominees for directors where death, illness, or other circumstances arise which prevent any management nominee or nominees for directors from serving in such positions and to vote such proxy for such substitute nominee or nominees.

-3-

Section 6. Record Date. The Board of Directors shall have authority to fix in advance a date not exceeding sixty (60) days preceding the date of any meeting of stockholders, or the date for the payment of any dividend, or the date for the allotment of rights, or the date when any change or conversion or exchange of capital stock shall go into effect, or a date in connection with obtaining the consent of stockholders for any purpose, as a record date for the determination of the stockholders entitled to notice of and to vote at any such meeting and any adjournments thereof, or entitled to receive payment of any such dividend or to any such allotment of rights, or to exercise the rights in respect of any change, conversion or exchange of capital stock, or to give such consent, and in such case such stockholders and only such stockholders as shall be stockholders of record at the close of business on the date so fixed shall be entitled to such notice of and to vote at such meeting and any adjournments thereof, or to receive payment of such dividend, or to receive such allotment of rights, or to exercise such rights, or to give such consent, as the case may be, notwithstanding any transfer of any stock on the books of the corporation after any such record date fixed aforesaid.

Section 7. Notice of Stockholder Business and Nominations.

(A) Annual Meetings of Stockholders. (1) Nominations of persons for election to the Board of Directors of the corporation and the proposal of other business to be considered by the stockholders may be made at an annual meeting of stockholders only (a) pursuant to the corporation’s notice of meeting (or any supplement thereto), (b) by or at the direction of the Board of Directors or any committee thereof or (c) by any stockholder of the corporation who was a stockholder of record of the corporation at the time the notice provided for in this Section 7 is delivered to the Secretary of the corporation, who is entitled to vote at the meeting and who complies with the notice procedures set forth in this Section 7.

-4-

(2) For any nominations or other business to be properly brought before an annual meeting by a stockholder pursuant to clause (c) of paragraph (A)(1) of this Section 7, the stockholder must have given timely notice thereof in writing to the Secretary of the corporation and any such proposed business (other than the nominations of persons for election to the Board of Directors) must constitute a proper matter for stockholder action. To be timely, a stockholder’s notice shall be delivered to the Secretary at the principal executive offices of the corporation not later than the close of business on the ninetieth (90^th) day, nor earlier than the close of business on the one hundred twentieth (120th) day, prior to the first anniversary of the preceding year’s annual meeting (provided, however, that in the event that the date of the annual meeting is more than thirty (30) days before or more than seventy (70) days after such anniversary date, notice by the stockholder must be so delivered not earlier than the close of business on the one hundred twentieth (120th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90^th) day prior to such annual meeting or the tenth (10^th) day following the day on which public announcement of the date of such meeting is first made by the corporation). In no event shall the public announcement of an adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above. Such stockholder’s notice shall set forth: (a) as to each person whom the stockholder proposes to nominate for election as a director (i) all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to and in

-5-

accordance with Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, and (ii) such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected; (b) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend the By-Laws of the corporation, the language of the proposed amendment), the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (c) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on the corporation’s books, and of such beneficial owner, (ii) the class or series and number of shares of capital stock of the corporation which are owned beneficially and of record by such stockholder and such beneficial owner, (iii) a description of any agreement, arrangement or understanding with respect to the nomination or proposal between or among such stockholder and/or such beneficial owner, any of their respective affiliates or associates, and any others acting in concert with any of the foregoing, including, in the case of a nomination, the nominee, (iv) a description of any agreement, arrangement or understanding (including any derivative or short positions, profit interests, options, warrants, convertible securities, stock appreciation or similar rights, hedging transactions, and borrowed or loaned shares) that has been entered into as of the date of the stockholder’s notice by, or on behalf of, such stockholder and such beneficial owners, whether or not such instrument or right

-6-

shall be subject to settlement in underlying shares of capital stock of the corporation, the effect or intent of which is to mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of, such stockholder or such beneficial owner, with respect to securities of the corporation, (v) a representation that the stockholder is a holder of record of stock of the corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business or nomination, (vi) a representation whether the stockholder or the beneficial owner, if any, intends or is part of a group which intends (a) to 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 to solicit proxies or votes from stockholders in support of such proposal or nomination, and (vii) any other information relating to such stockholder and beneficial owner, if any, required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for, as applicable, the proposal and/or for the election of directors in an election contest pursuant to and in accordance with Section 14(a) of the Exchange Act and the rules and regulations promulgated thereunder. The foregoing notice requirements of this paragraph (A) of this Section 7 shall be deemed satisfied by a stockholder with respect to business other than a nomination if the stockholder has notified the corporation of his, her or its intention to present a proposal at an annual meeting in compliance with applicable rules and regulations promulgated under the Exchange Act and such stockholder’s proposal has been included in a proxy statement that has been prepared by the corporation to solicit proxies for such annual meeting. The corporation may require any proposed nominee to furnish such other information as the corporation may reasonably require to determine the eligibility of such proposed nominee to serve as a director of the corporation.

-7-

(3) Notwithstanding anything in the second sentence of paragraph (A)(2) of this Section 7 to the contrary, in the event that the number of directors to be elected to the Board of Directors of the corporation at the annual meeting is increased effective after the time period for which nominations would otherwise be due under paragraph (A)(2) of this Section 7 and there is no public announcement by the corporation naming the nominees for the additional directorships 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 Section 7 shall also be considered timely, but only with respect to nominees for the additional directorships, 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 (10^th) day following the day on which such public announcement is first made by the corporation.

(B) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the corporation’s notice of meeting. Nominations of persons for election to the Board of Directors may be made at a special meeting of stockholders at which directors are to be elected pursuant to the corporation’s notice of meeting (1) by or at the direction of the Board of Directors or any committee thereof (or stockholders pursuant to Article I, Section 2 hereof) or (2) provided that the Board of Directors (or stockholders pursuant to Article I, Section 2 hereof) has determined that directors shall be elected at such meeting, by any stockholder of the corporation who is a stockholder of record at the time the notice provided for in this Section 7 is delivered to the Secretary of the corporation, who

-8-

is entitled to vote at the meeting and upon such election and who complies with the notice procedures set forth in this Section 7. The proposal by stockholders of other business to be conducted at a special meeting of stockholders may be made only in accordance with Article I, Section 2 hereof. In the event the corporation calls a special meeting of stockholders for the purpose of electing one or more directors to the Board of Directors, any such stockholder entitled to vote in such 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 stockholder’s notice required by paragraph (A)(2) of this Section 7 shall be delivered to the Secretary at the principal executive offices of the corporation not earlier than the close of business on the one hundred twentieth (120^th) day prior to such special meeting and not later than the close of business on the later of the ninetieth (90^th) day prior to such special meeting or the tenth (10^th) day 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 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 stockholder’s notice as described above.

(C) General. (1) Except as otherwise expressly provided in any applicable rule or regulation promulgated under the Exchange Act, only such persons who are nominated in accordance with the procedures set forth in this Section 7 shall be eligible to be elected at an annual or special meeting of stockholders of the corporation to serve as directors and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 7. Except as otherwise provided by law, the chairman of the meeting shall have the power

-9-

and duty (a) to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in this Section 7 (including whether the stockholder or beneficial owner, if any, on whose behalf the nomination or proposal is made or solicited (or is part of a group which solicited) or did not so solicit, as the case may be, proxies or votes in support of such stockholder’s nominee or proposal in compliance with such stockholder’s representation as required by clause (A)(2)(c)(vi) of this Section 7) and (b) if any proposed nomination or business was not made or proposed in compliance with this Section 7, to declare that such nomination shall be disregarded or that such proposed business shall not be transacted. Notwithstanding the foregoing provisions of this Section 7, unless otherwise required by law, if the stockholder (or a qualified representative of the stockholder) does not appear at the annual or special meeting of stockholders of the corporation to present a nomination or proposed business, such nomination shall be disregarded and such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the corporation. For purposes of this Section 7, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

(2) For purposes of this Section 7, “public announcement” shall include disclosure in a press release reported by the Dow Jones News Service, Associated Press

-10-

or other 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 and the rules and regulations promulgated thereunder.

(3) Notwithstanding the foregoing provisions of this Section 7, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations promulgated thereunder with respect to the matters set forth in this Section 7; provided however, that any references in these By-Laws to the Exchange Act or the rules and regulations promulgated thereunder are not intended to and shall not limit any requirements applicable to nominations or proposals as to any other business to be considered pursuant to this Section 7 (including paragraphs (A)(1)(c) and (B) hereof), and compliance with paragraphs (A)(1)(c) and (B) of this Section 7 shall be the exclusive means for a stockholder to make nominations or submit other business (other than, as provided in the penultimate sentence of (A)(2), business other than nominations brought properly under and in compliance with Rule 14a-8 of the Exchange Act, as may be amended from time to time). Nothing in this Section 7 shall be deemed to affect any rights (a) of stockholders to request inclusion of proposals or nominations in the corporation’s proxy statement pursuant to applicable rules and regulations promulgated under the Exchange Act or (b) of the holders of any series of Preferred Stock to elect directors pursuant to any applicable provisions of the certificate of incorporation.

This corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether, civil, criminal, administrative or investigative (other than an action by or in the right of this corporation) by reason of the fact that he is or was a director, officer, employee or agent of this corporation, or is or was serving at the request of this corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of this corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere

-17-

or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of this corporation, and with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

Section 2. This corporation shall indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action or suit by or in the right of this corporation to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of this corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of this corporation, and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to this corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such expenses which the Court of Chancery or such other court shall deem proper.

Section 3. To the extent that a director, officer, employee or agent of this corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Sections 1 and 2, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorney’s fees) actually and reasonably incurred by him in connection therewith.

-18-

Section 4. Any indemnification under Section 1 and 2 (unless ordered by a court) shall be made by this corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Sections 1 and 2. Such determination shall be made (1) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable, a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (3) by the stockholders.

The corporation may require, as a condition precedent to the issuance of a new certificate or uncertificated shares in place of any certificate, the owner of such lost, stolen, or destroyed certificate or certificates, or his legal representative, to advertise the same in such manner as it shall require or to give the corporation a surety bond in such form and amount as it may direct as indemnity against any claim that may be made against the corporation with respect to the certificate alleged, to have been lost, stolen, or destroyed.

Section 3. Transfers.

(a) Transfers of record of shares of stock of the corporation shall be made only upon its books by the holders thereof, in person or by attorney duly authorized, and upon the surrender of a properly endorsed certificate or certificates or evidence of uncertificated shares, for a like number of shares.

CORPORATE GOVERNANCE GUIDELINES

J. Director Resignation Policy

1. Promptly following the receipt of the final report from the inspector of election relating to an election of directors (other than elections in which the number of nominees exceeds the number of directors to be elected), any nominee who receives a greater number of votes “withheld” from his or her election than votes “for” his or her election, will tender his or her resignation for consideration by the Board. Subject to paragraphs 3 and 4 below, the Governance and Stockholder Relations Committee (the “Governance Committee”) will meet to consider the tendered resignation and make a recommendation to the Board concerning the action, if any, to be taken with respect to the resignation.

2. The Board will consider and act upon the Governance Committee’s recommendation within 90 days of certification of the vote at the annual meeting. In considering the resignation, the Governance Committee and the Board will consider all factors they deem relevant, including, without limitation, the underlying reason for the vote result, if known, the director’s contributions to the Company during his or her tenure, and the director’s qualifications. The Board may accept the resignation, refuse the resignation, or refuse the resignation subject to such conditions designed to cure the underlying cause as the Board may impose.

3. Subject to paragraph 4 of this Director Resignation Policy, any director nominee who tenders a resignation pursuant to the foregoing policy will not participate, as a member of either the Governance Committee or of the Board, in any deliberations concerning his or her resignation or the resignation of any other director nominee who similarly tendered his or her resignation by virtue of the vote at the same annual meeting of stockholders. If with respect to the same annual meeting of stockholders a majority of the members of the Governance Committee are required to tender their resignation pursuant to this policy, then, provided that there are at least two directors on the Board who the Board has determined to be “independent” pursuant to this policy and who are not required to tender their resignations in connection with the same annual meeting of stockholders (the “Non-Tendering Directors”), the Board will establish an ad hoc committee comprised of Non-Tendering Directors, and such committee will assume the role of the Governance Committee with respect to the tendered resignations. Notwithstanding the foregoing, if there are not at least two Non-Tendering Directors on the Board in connection with an annual meeting of stockholders, then the Board will consider the tendered resignations without the prior recommendation of a Board committee.

4. Notwithstanding anything to the contrary in this Director Resignation Policy, if the only directors who are not required to tender their resignations pursuant to these guidelines in connection with the same annual meeting of stockholders constitute three or fewer directors, then all the independent directors on the Board will participate in the Board’s consideration of whether to accept or reject the tendered resignations (whether the Board’s consideration follows a prior recommendation of the Governance Committee or a committee of Non-Tendering Directors or whether there is no Board committee involvement pursuant to paragraph 3 above), provided that a director will not participate in deliberations concerning his or her own resignation.

5. Within four business days of the decision regarding the tendered resignation, the Company will file with the SEC a report on Form 8-K disclosing the decision with respect to the resignation, describing the deliberative process and, if applicable, the specific reasons for rejecting the tendered resignation.
