Section 3.Special Meetings.

(a)    Special meetings of the stockholders of the Corporation may be called, for any purpose or purposes, by the Chairman of the Board or the President or the Board of Directors at any time. Stockholders' ability to cause a special meeting to be held is described in Section 3(b) below.

(b)    Subject to the provisions of this Section 3(b) and all other applicable sections of these By-Laws, a special meeting of stockholders shall be called by the Secretary of the Corporation upon written request (a “Special Meeting Request”) of one or more persons who or which Net Long Beneficially Own(s) not less than 25% of the outstanding shares of common stock of the Corporation (the “Requisite Percentage”) as of the time of such request and has or have had continuous Net Long Beneficial Ownership of at least the Requisite Percentage for a minimum of one full year prior to the date of submission of the Special Meeting Request.

(i)A Special Meeting Request must be delivered by hand or by registered U.S. mail, postage prepaid, return receipt requested, or courier service, postage prepaid, to the attention of the Secretary of the Corporation at the principal executive offices of the Corporation. A Special Meeting Request shall be valid only if it is signed and dated by each stockholder of record submitting the Special Meeting Request and each beneficial owner, if any, on whose behalf the Special Meeting Request is being made, or such stockholder's or beneficial owner's duly authorized agent (each, a “Requesting Stockholder”), and includes (A) a statement of the specific purpose(s) of the special meeting and the reasons for conducting such business at the special meeting; (B) in the case of any director nominations proposed to be presented at the special meeting, the information required by Section 10(c) of this Article II; (C) in the case of any matter (other than a director nomination) proposed to be conducted at the special meeting, the information required by Section 9(c) of this Article II; (D) a representation that each Requesting Stockholder, or one or more representatives of each such stockholder, intends to appear in person or by proxy at the special meeting to present the proposal(s) or business to be brought before the special meeting; (E) an agreement by the Requesting Stockholders to notify the Corporation promptly in the event of (1) any disposition prior to the time of the special meeting of any shares included within any Requesting Stockholder's Net Long Beneficial Ownership as of the date on which the Special Meeting Request was delivered to the Secretary and (2) any material change prior to the time of the special meeting in any Requesting Stockholder's Net Long Beneficial Ownership; (F) an acknowledgement that prior to the special meeting any disposition of shares of the Corporation's common stock included within any Requesting Stockholder's Net Long Beneficial Ownership as of the date on which the Special Meeting Request was delivered to the Secretary shall be deemed to be a revocation of such Special Meeting Request with respect to such disposed shares and that any decrease in the Requesting Stockholders' aggregate Net Long Beneficial Ownership to less than the Requisite Percentage shall be deemed to be an absolute revocation of such Special Meeting Request; and (G) documentary evidence that the Requesting Stockholders had Net Long Beneficial Ownership of the Requisite Percentage as of the date of delivery of the Special Meeting Request to the Secretary and for a minimum of one full year prior to the date of such delivery; provided, however, that if any of the Requesting Stockholders are not the beneficial owners of the shares representing the Requisite Percentage, then to be valid, the Special Meeting Request must also include documentary evidence (or, if not

-4-

simultaneously provided with the Special Meeting Request, such documentary evidence must be delivered to the Secretary within ten days after the date of delivery of the Special Meeting Request to the Secretary) that the beneficial owners on whose behalf the Special Meeting Request is made had, together with any Requesting Stockholders who are beneficial owners, Net Long Beneficial Ownership of the Requisite Percentage as of the date of delivery of such Special Meeting Request to the Secretary and for a minimum of one full year prior to the date of such delivery. In addition, the Requesting Stockholders on whose behalf the Special Meeting Request is being made shall (x) further update and supplement the information provided in the Special Meeting Request, if necessary, so that the information provided or required to be provided therein shall be true and correct as of the record date for the special meeting and as of the date that is ten business days prior to the date of the special meeting or any adjournment or postponement thereof, or, if there are fewer than ten business days between the date of the special meeting and such adjourned or postponed meeting, then as of the date of the special meeting so adjourned or postponed, and such update and supplement shall be delivered to, or mailed and received by, the Secretary at the principal executive offices of the Corporation not later than five business days after the record date for notice of and voting at the special meeting (in the case of an update and supplement required to be made as of such record date), and not later than eight business days prior to the date of the special meeting or, if practicable, any adjournment or postponement thereof (and, if not practicable, on the first practicable date prior to the date to which the special meeting has been adjourned or postponed) (in the case of an update and supplement required to be made as of ten business days prior to the meeting or any adjournment or postponement thereof) and (y) promptly provide any other information reasonably requested by the Corporation.

(ii)A Special Meeting Request shall not be valid, and a special meeting requested by stockholders shall not be held, if (A) the Special Meeting Request does not comply with this Section 3(b); (B) the Special Meeting Request relates to an item of business that is not a proper subject for stockholder action under applicable law; (C) the Special Meeting Request is delivered during the period commencing 120 days prior to the first anniversary of the date of the immediately preceding annual meeting of stockholders and ending on the earlier of (x) the date of the next annual meeting or (y) 30 days after the first anniversary of the date of the previous annual meeting; (D) an identical or substantially similar item (as determined in good faith by the Board, a “Similar Item”), other than the election of directors, (1) was presented at an annual or special meeting of stockholders held not more than 12 months before delivery of the Special Meeting Request or (2) is included in the Corporation's notice of meeting as an item of business to be brought before an annual or special meeting of stockholders that has been called but not yet held or that is called for a date within 120 days of the receipt by the Corporation of a Special Meeting Request; (E) a proposed item of business involves the election or removal of directors, changing the size of the Board of Directors, the filling of vacancies and/or newly created directorships resulting from any increase in the authorized number of directors or any similar matter (as determined in good faith by the Board, an “Election Item”) and any Election Item (1) was presented at an annual or special meeting of stockholders held not more than 120 days before delivery of the Special Meeting Request or (2) is included in the Corporation's notice of meeting as an item of business to be brought before an annual or special meeting of stockholders that has been called but not yet held or that is called for a date within 120 days of the receipt by

-5-

the Corporation of a Special Meeting Request ; or (F) the Special Meeting Request was made in a manner that involved a violation of Regulation 14A under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or other applicable law.

(iii)Special meetings of stockholders called pursuant to this Section 3(b) shall be held at such place, on such date, and at such time as the Board of Directors shall fix; provided, however, that the special meeting shall not be held more than 120 days after receipt by the Corporation of a valid Special Meeting Request.

(iv)The Requesting Stockholders may revoke a Special Meeting Request by written revocation delivered to the Secretary at the principal executive offices of the Corporation at any time prior to the special meeting. If, following such revocation (or any deemed revocation pursuant to clause (F) of Section 3(b)(i)), there are unrevoked requests from Requesting Stockholders holding in the aggregate less than the Requisite Percentage (or there are no unrevoked requests at all), the Board, in its discretion, may cancel the special meeting.

(v)If none of the Requesting Stockholders appears or sends a duly authorized agent to present the business specified in the Special Meeting Request to be presented for consideration, the Corporation need not present such business for a vote at the special meeting, notwithstanding that proxies in respect of such business may have been received by the Corporation.

(vi)Business transacted at any special meeting called pursuant to this Section 3(b) shall be limited to (A) the purpose(s) stated in a valid Special Meeting Request received from the Requesting Stockholders holding in the aggregate the Requisite Percentage and (B) any additional matters that the Board determines to include in the Corporation's notice of the special meeting.

(vii)For the purposes of this Section 3(b), the following definitions shall apply:

An “Affiliate” of a person shall mean another person that, directly or indirectly through one of more intermediaries, controls, is controlled by or is under common control with such person.

An “Associate” of a person shall mean (i) any corporation or organization (other than a majority-owned subsidiary of such person) of which such person is an officer or partner or is, directly or indirectly, the beneficial owner of ten percent or more of any class of equity securities; (ii) any trust or other estate in which such person has a substantial beneficial interest or as to which such person serves as trustee or in a similar fiduciary capacity; and (iii) any relative or spouse of such person, or any relative of such spouse, who has the same home as such person or who is a director or officer of the Corporation or any of its parents or subsidiaries.

“Net Long Beneficial Ownership” (and its correlative terms), when used to describe the nature of a person's ownership of common stock of the Corporation, shall mean the shares of stock of the Corporation that such person or, if such person is a nominee, custodian or other agent that is holding the shares on behalf of another person (the “beneficial owner”), that such beneficial owner would then be deemed to own pursuant to Rule 200(b) under the Exchange Act (as such

-6-

Rule is in effect on the date on which the By-Laws are first amended to include this Section 3(b)), excluding, at any time, any shares as to which such stockholder or beneficial owner, as the case may be, does not then have the right to vote or direct the vote and excluding, at any time, any shares as to which such person or beneficial owner (or any Affiliate or Associate of such person or beneficial owner), as the case may be, had directly or indirectly entered into (or caused to be entered into) and not yet terminated a derivative or other agreement, arrangement or understanding that hedges or transfers, in whole or in part, directly or indirectly, any of the economic consequences of ownership of such shares, and further subtracting from any person's ownership of shares at any time such person's (and such person's Affiliates' and Associates') “short position” (as defined pursuant to Rule 14e-4(a) under the Exchange Act) (as such Rule is in effect on the date on which the By-Laws are first amended to include this Section 3(b)), all as the Board of Directors shall determine in good faith. The Board of Directors shall determine in good faith whether all requirements set forth in this Section 3(b) have been satisfied and such determination shall be binding on the Corporation and its stockholders.

Section 4.Notice of Meetings.

(a)Except as otherwise provided by law or the Certificate of Incorporation, written notice of each meeting of stockholders, specifying the place, date and hour and purpose or purposes of the meeting, shall be given not less than 10 nor more than 60 days before the date of the meeting to each stockholder entitled to vote thereat, directed to such stockholder's address as it appears upon the books of the Corporation; except that where the matter to be acted on is a merger or consolidation of the Corporation or a sale, lease or exchange of all or substantially all of its assets, such notice shall be given not less than 20 nor more than 60 days prior to such meeting. Such notice may be given in any form or manner permitted by the Delaware General Corporation Law, including Section 232 thereof relating to notice by electronic transmission.

(b)If at any meeting action is proposed to be taken which, if taken, would entitle stockholders fulfilling the requirements of Section 262(d) of the Delaware General Corporation Law to an appraisal of the fair value of their shares, the notice of such meeting shall contain a statement to that effect and shall be accompanied by a copy of that statutory section.

(c)When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken unless the adjournment is for more than 30 days, or unless after the adjournment a new record date is fixed for the adjourned meeting, in which event a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

(d)Notice of the time, place and purpose of any meeting of stockholders may be waived in writing, either before or after such meeting, and to the extent permitted by law, will be waived by any stockholder by such stockholder's attendance thereat, in person or by proxy. Any stockholder so waiving notice of such meeting shall be bound by the proceedings of any such meeting in all respects as if due notice thereof had been given.

-7-

(e)Unless and until voted, every proxy shall be revocable at the pleasure of the person who executed it or of such person's legal representatives or assigns, except in those cases where an irrevocable proxy permitted by statute has been given.

Section 5.Quorum. At all meetings of stockholders, except where otherwise provided by law, the Certificate of Incorporation, or these By-Laws, the presence, in person or by proxy duly authorized, of the holders of a majority of the outstanding shares of stock entitled to vote shall constitute a quorum for the transaction of business. Shares, the voting of which at such meeting has been enjoined, or which for any reason cannot be lawfully voted at such meeting, shall not be counted to determine a quorum at such meeting.

In the absence of a quorum any meeting of stockholders may be adjourned, from time to time, by vote of the holders of a majority of the shares represented thereat, but no other business shall be transacted at such meeting. At such adjourned meeting at which a quorum is present or represented any business may be transacted which might have been transacted at the original meeting. The stockholders present at a duly called or convened meeting, at which a quorum is present, may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. Except as otherwise provided by law, the Certificate of Incorporation or these By-Laws, the affirmative vote of the majority of shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of the stockholders.

In the event that at any meeting at which the holders of more than one class or series of the Corporation's capital stock are entitled to vote as a class, a quorum of any such class or series is lacking, the holders of any class or series represented by a quorum may proceed with the transaction of the business to be transacted by such class or series, and if such business is the election of directors, the directors whose successors shall not have been elected shall continue in office until their successors shall have been duly elected and shall have qualified.

Section 6.Voting Rights.

(a)Except as otherwise provided by law, only persons in whose names shares entitled to vote stand on the stock records of the Corporation on the record date for determining the stockholders entitled to vote at such meeting shall be entitled to vote at such meeting. Shares standing in the names of two or more persons shall be voted or represented in accordance with the determination of the majority of such persons, or, if only one of such persons is present in person or represented by proxy, such person shall have the right to vote such shares and such shares shall be deemed to be represented for the purpose of determining a quorum.

(b)Every person entitled to vote or execute consents shall have the right to do so either in person or by an agent or agents authorized by a written proxy executed by such person or such person's duly authorized agent, which proxy shall be filed with the Secretary of the Corporation at or before the meeting at which it is to be used. Said proxy so appointed need not be a stockholder. No proxy shall be voted on after three years from its date unless the proxy provides for a longer period.

-8-

(c)Without limiting the manner in which a stockholder may authorize another person or persons to act for such stockholder as proxy pursuant to subsection (b) of this Section, the following shall constitute a valid means by which a stockholder may grant such authority:

(i)A stockholder may execute a writing authorizing another person or persons to act for such stockholder as proxy. Execution may be accomplished by the stockholder or such stockholder's authorized officer, director, employee or agent signing such writing or causing such stockholder's signature to be affixed to such writing by any reasonable means including, but not limited to, by facsimile signature.

(ii)A stockholder may authorize another person or persons to act for such stockholder as proxy by transmitting or authorizing the transmission of a telegram, cablegram, or other means of electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization or like agent duly authorized by the person who will be the holder of the proxy to receive such transmission, provided that any such telegram, cablegram or other means of electronic transmission must either set forth or be submitted with information from which it can be determined that the telegram, cablegram or other electronic transmission was authorized by such stockholder. If it is determined that such telegrams, cablegrams or other electronic transmissions are valid, the inspectors or, if there are no inspectors, such other persons making that determination shall specify the information upon which they relied.

(d)Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission created pursuant to subsection (c) of this Section may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission.

Section 7.Voting Procedures and Inspectors of Elections.

(a)The Corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors to act at the meeting and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the person presiding at the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability.

(b)The inspectors shall (i) ascertain the number of shares outstanding and the voting power of each, (ii) determine the shares represented at a meeting and the validity of proxies and ballots, (iii) count all votes and ballots, (iv) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspectors, and (v) certify their determination of the number of shares represented at the meeting, and their count of all votes and ballots. The inspectors may appoint or retain other persons or entities to assist the inspectors in the performance of the duties of the inspectors.

-9-

(c)The date and time of the opening and the closing of the polls for each matter upon which the stockholders will vote at a meeting shall be announced at the meeting. No ballot, proxies or votes, nor any revocations thereof or changes thereto, shall be accepted by the inspectors after the closing of the polls unless the Court of Chancery upon application by a stockholder shall determine otherwise.

(d)In determining the validity and counting of proxies and ballots, the inspectors shall be limited to an examination of the proxies, any envelopes submitted with those proxies, any information provided in accordance with Section 212(c)(2) of the Delaware General Corporation Law, ballots and the regular books and records of the Corporation, except that the inspectors may consider other reliable information for the limited purpose of reconciling proxies and ballots submitted by or on behalf of banks, brokers, their nominees or similar persons which represent more votes than the holder of a proxy is authorized by the record owner to cast or more votes than the stockholder holds of record. If the inspectors consider other reliable information for the limited purpose permitted herein, the inspectors at the time they make their certification pursuant to subsection (b)(v) of this Section shall specify the precise information considered by them, including the person or persons from whom they obtained the information, when the information was obtained, the means by which the information was obtained and the basis for the inspectors' belief that such information is accurate and reliable.

(e)The provisions of this Section 7 shall not apply to any annual meeting of stockholders held prior to the annual meeting of stockholders held in 1995.

Section 8.List of Stockholders. The officer who has charge of the stock ledger of the Corporation shall prepare and make, at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at said meeting, arranged in alphabetical order, showing the address of and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten days prior to the meeting, either at a place within the city where the meeting is to be held and which place shall be specified in the notice of the meeting, or, if not specified, at the place where said meeting is to be held, and the list shall be produced and kept at the time and place of meeting during the whole time thereof, and may be inspected by any stockholder who is present.

Section 9.Stockholder Proposals at Annual Meetings.

(a)At an annual meeting of the stockholders, only such business (other than nominations for election to the Board of Directors, which must comply with the provisions of ARTICLE II, Section 10) shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual meeting, business must be (i) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors (or any duly authorized committee thereof) or (ii) otherwise properly brought before the meeting by or at the direction of the Board of Directors (or any duly authorized committee thereof) or (iii) otherwise properly brought before the meeting by a stockholder of the Corporation (A) who is a stockholder of record on the date of the giving of the notice provided for in this Section 9 and on

-10-

the record date for the determination of stockholders entitled to vote at such annual meeting and (B) who complies with the notice procedures set forth in this Section 9.

(b)In addition to any other applicable requirements, for business to be properly brought before an annual meeting by a stockholder, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation. To be timely, a stockholder's notice to the Secretary must be delivered to or mailed and received at the principal executive offices of the Corporation, not less than 90 days nor more than 120 days prior to the anniversary date of the immediately preceding annual meeting of stockholders; provided, however, that in the event that the annual meeting is called for a date that is not within 25 days before or after such anniversary date, notice by the stockholder in order to be timely must be so received not later than the close of business on the tenth day following the day on which such notice of the date of the annual meeting was mailed or such public disclosure (as defined below) of the date of the annual meeting was made, whichever first occurs. In no event shall the public disclosure of an adjournment or postponement of an annual meeting commence a new time period for the giving of a stockholder's notice as described above.

(c)To be in proper form, a stockholder's notice to the Secretary shall set forth as to each matter the stockholder proposes to bring before the annual meeting, (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting; (ii) as to the stockholder giving notice and the beneficial owner, if any, on whose behalf the proposal is being made, (A) the name and address of such person, (B) the class, series and number of all shares of stock of the Corporation which are owned beneficially or of record by such person, (C) the name of each nominee holder for, and the number of, shares owned beneficially but not of record by each such person and (D) whether and the extent to which any hedging or other transaction has been entered into by or on behalf of such stockholder with respect to the stock of the Corporation and whether and the extent to which any other transaction, agreement, arrangement or understanding (including any derivative or short positions, profit interests, options, warrants, stock appreciation or similar rights or borrowing or lending shares of stock) has been made by or on behalf of such stockholder, the effect or intent of any of the foregoing being to manage the risk or benefit of share price changes in the stock price of the Corporation for such person or to increase or decrease the voting power or pecuniary or economic interest of such person with respect to stock of the Corporation; (iii) a description of all agreements, arrangements or understandings (whether written or oral) between or among the stockholder giving the notice and on whose behalf the proposal is being made and any other person or persons in connection with the proposal and any material interest in such business, including any anticipated benefit to such person or persons therefrom; (iv) a representation that the stockholder giving notice intends to appear in person or by proxy at the annual meeting to bring such business before the meeting; (v) a representation whether the stockholder or the beneficial owner, if any, intends, or is part of a group that intends, to deliver a proxy statement or form of proxy to holders of at least the percentage of the Corporation's outstanding shares required to approve or adopt the proposal or otherwise solicit proxies from stockholders in support of the proposal; and (vi) any other information relating to the stockholder giving the notice and on whose behalf the proposal is being made that would be required to be disclosed in a proxy statement or other filing required to be made in connection with the

-11-

solicitation of proxies with respect to business brought at an annual meeting of stockholders pursuant to Section 14 of the Exchange Act, and the rules and regulations promulgated thereunder.

(d)A stockholder providing notice of business proposed to be brought before an annual meeting shall further update and supplement such notice, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 9 shall be true and correct as of the record date for the meeting, and such update and supplement shall be delivered to or mailed and received by the Secretary at the principal executive offices of the Corporation not later than five business days after the record date for the meeting.

(e)Notwithstanding anything in the By-Laws to the contrary, no business shall be conducted at the annual meeting except in accordance with the procedures set forth in this Section 9, provided, however, that nothing in this Section 9 shall be deemed to preclude discussion by any stockholder of any business properly brought before the annual meeting in accordance with said procedures.

(f)The Chairman of an annual meeting shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting in accordance with the provisions of this Section 9, and if he should so determine, he shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.

(g)For purposes of ARTICLE II, Sections 9 and 10 of these By-Laws, “public disclosure” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act.

(h)Nothing contained in this Section 9 shall be deemed to affect any rights of stockholders to request inclusion of proposals in the Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act (or any successor provision of law).

Section 10.Nominations of Persons for Election to the Board of Directors.

(a)In addition to any other applicable requirements, only persons who are nominated in accordance with the following procedures shall be eligible for election as directors. Nominations of persons for election to the Board of Directors of the Corporation may be made at any annual meeting of stockholders, or at any special meeting of stockholders called for the purpose of electing directors, (i) by or at the direction of the Board of Directors (or any duly authorized committee thereof) or (ii) by any nominating committee or person appointed by the Board of Directors or (iii) by any stockholder of the Corporation (A) who is a stockholder of record on the date of the giving of the notice provided for in this Section 10 and on the record date for the determination of stockholders entitled to vote at such annual or special meeting and (B) who complies with the notice procedures set forth in this Section 10.

The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful. The right to indemnification conferred in this ARTICLE VIII shall be a contract right.

Subject to Section 3 of this ARTICLE VIII, the Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he or she is or was a director or officer of the Corporation, or is or was a director or officer of the Corporation serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection with the defense or settlement of such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the

-24-

adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 3.Authorization of Indemnification. Any indemnification under this ARTICLE VIII (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director or officer is proper in the circumstances because he or she has met the applicable standard of conduct set forth in Section 1 or Section 2 of this ARTICLE VIII, as the case may be. Such determination shall be made (i) 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 (ii) 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 (iii) by the stockholders. To the extent, however, that a director or officer of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, he or she shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection therewith, without the necessity of authorization in the specific case.

Section 4.Good Faith Defined. For purposes of any determination under Section 3 of this ARTICLE VIII, a person shall be deemed to have acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation, or, with respect to any criminal action or proceeding, to have had no reasonable cause to believe his or her conduct was unlawful, if his or her action is based on the records or books of account of the Corporation or another enterprise, or on information supplied to him or her by the officers of the Corporation or another enterprise in the course of their duties, or on the advice of legal counsel for the Corporation or another enterprise or on information or records given or reports made to the Corporation or another enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Corporation or another enterprise. The term “another enterprise” as used in this Section 4 shall mean any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise of which such person is or was serving at the request of the Corporation as a director, officer, employee or agent. The provisions of this Section 4 shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of conduct set forth in Sections 1 or 2 of this ARTICLE VIII, as the case may be.

Section 5.Indemnification by a Court. Notwithstanding any contrary determination in the specific case under Section 3 of this ARTICLE VIII, and notwithstanding the absence of any determination thereunder, any director or officer may apply to any court of competent jurisdiction in the State of Delaware for indemnification to the extent otherwise permissible under Sections 1 and 2 of this ARTICLE VIII. The basis of such indemnification by a court shall be a determination by such court that indemnification of the director or officer is proper in the circumstances because he or she has met the applicable standards of conduct set forth in Sections 1 or 2 of this ARTICLE VIII, as the case may be. Neither a contrary determination in the specific case under Section 3 of this ARTICLE VIII nor the absence of any determination thereunder shall be a defense to such application or create a presumption that the director or officer seeking

-25-

indemnification has not met any applicable standard of conduct. Notice of any application for indemnification pursuant to this Section 5 shall be given to the Corporation promptly upon the filing of such application. If successful, in whole or in part, the director or officer seeking indemnification shall also be entitled to be paid the expense of prosecuting such application.

Section 6.Expenses Payable in Advance. Expenses incurred by a director or officer in defending or investigating a threatened or pending action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the Corporation as authorized in this ARTICLE VIII.

Section 7.Nonexclusivity of Indemnification and Advancement of Expenses. The indemnification and advancement of expenses provided by or granted pursuant to this ARTICLE VIII shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any By-Law, agreement, contract, vote of stockholders or disinterested directors or pursuant to the direction (howsoever embodied) of any court of competent jurisdiction or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office, it being the policy of the Corporation that indemnification of the persons specified in Sections 1 and 2 of this ARTICLE VIII shall be made to the fullest extent permitted by law. The provisions of this ARTICLE VIII shall not be deemed to preclude the indemnification of any person who is not specified in Sections 1 or 2 of this ARTICLE VIII but whom the Corporation has the power or obligation to indemnify under the provisions of the General Corporation Law of the State of Delaware, or otherwise.

Section 8.Insurance. The Corporation may purchase and maintain insurance on behalf of any person who is or was a director or officer of the Corporation, or is or was a director or officer of the Corporation serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the Corporation would have the power or the obligation to indemnify him or her against such liability under the provisions of this ARTICLE VIII.

Section 9.Certain Definitions. For purposes of this ARTICLE VIII, references to “the Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors or officers, so that any person who is or was a director or officer of such constituent corporation, or is or was a director or officer of such constituent corporation serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, shall stand in the same position under the provisions of this ARTICLE VIII with respect to the resulting or surviving corporation as he or she would have with respect to such constituent corporation if its separate existence had continued. For purposes of this ARTICLE VIII, references to “fines” shall include

-26-

any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Corporation” shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director or officer with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he or she reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Corporation” as referred to in this ARTICLE VIII.

Section 10.Survival of Indemnification and Advancement of Expenses. The indemnification and advancement of expenses provided by, or granted pursuant to, this ARTICLE VIII shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person.

Section 11.Limitation on Indemnification. Notwithstanding anything contained in this ARTICLE VIII to the contrary, except for proceedings to enforce rights to indemnification (which shall be governed by Section 5 hereof), the Corporation shall not be obligated to indemnify any director or officer in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by the Board of Directors of the Corporation.

Section 12.Indemnification of Employees and Agents. The Corporation may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification and to the advancement of expenses to employees and agents of the Corporation similar to those conferred in this ARTICLE VIII to directors and officers of the Corporation.

Section 13.Effect of Amendment. Any amendment, repeal or modification of this ARTICLE VIII shall not (a) adversely affect any right or protection of any director or officer existing at the time of such amendment, repeal or modification, or (b) apply to the indemnification of any such person for liability, expense, or loss stemming from actions or omissions occurring prior to such amendment, repeal, or modification.

Section 14.Authority to Enter into Indemnification Agreements. The Corporation may enter into indemnification agreements with the directors and officers of the Corporation.

ARTICLE IX

Notices

Whenever, under any provisions of these By-Laws, notice is required to be given to any stockholder, the same shall be given in writing, timely and duly deposited in the United States Mail, postage prepaid, and addressed to such stockholder's last known post office address as shown by the stock record of the Corporation or its transfer agent. Any notice required to be given to any director may be given by any of the methods stated in Section 8 of ARTICLE III hereof, except that such notice other than one which is delivered personally, shall be sent to such

-27-

address or (in the case of facsimile telecommunication) facsimile telephone number as such director shall have disclosed in writing to the Secretary of the Corporation, or, in the absence of such filing, to the last known post office address of such director. If no address of a stockholder or director be known, such notice may be sent to the office of the Corporation required to be maintained pursuant to Section 2 of ARTICLE I hereof. An affidavit of mailing, executed by a duly authorized and competent employee of the Corporation or its transfer agent appointed with respect to the class of stock affected, specifying the name and address or the names and addresses of the stockholder or stockholders, director or directors, to whom any such notice or notices was or were given, and the time and method of giving the same, shall be conclusive evidence of the statements therein contained. All notices given by mail, as above provided, shall be deemed to have been given as at the time of mailing and all notices given by telegram or other means of electronic transmission shall be deemed to have been given as at the sending time recorded by the telegraph company or other electronic transmission equipment operator transmitting the same. It shall not be necessary that the same method of giving be employed in respect of all directors, but one permissible method may be employed in respect of any one or more, and any other permissible method or methods may be employed in respect of any other or others. The period or limitation of time within which any stockholder may exercise any option or right, or enjoy any privilege or benefit, or be required to act, or within which any director may exercise any power or right, or enjoy any privilege, pursuant to any notice sent such stockholder or such director in the manner above provided, shall not be affected or extended in any manner by the failure of such a stockholder or such director to receive such notice. Whenever any notice is required to be given under the provisions of this statute or of the Certificate of Incorporation, or of these By-Laws, a waiver thereof in writing signed by the person or persons entitled to said notice, whether before or after the time stated therein, shall be deemed equivalent thereto. Whenever notice is required to be given, under any provision of law or of the Certificate of Incorporation or By-Laws of the Corporation, to any person with whom communication is unlawful, the giving of such notice to such person shall not be required and there shall be no duty to apply to any governmental authority or agency for a license or permit to give such notice to such person. Any action or meeting which shall be taken or held without notice to any such person with whom communication is unlawful shall have the same force and effect as if such notice had been duly given. In the event that the action taken by the Corporation is such as to require the filing of a certificate under any provision of the Delaware General Corporation Law, the certificate shall state, if such is the fact and if notice is required, that notice was given to all persons entitled to receive notice except such persons with whom communication is unlawful.
