ARTICLE II.
MEETINGS OF STOCKHOLDERS

Section 2.1.  Place and Time of Meetings.  All meetings of the stockholders shall be held on such date and at such time and place, within or without the state of Delaware, as shall be determined, from time to time, by the board of directors or by means of remote communication at the discretion of the board of directors, as stated in the notice and call of the meeting or a duly executed waiver of notice thereof.  The chairman of the board, the president, the chief executive officer, the board of directors or the holders of at least 15 percent of the shares of the corporation that would be entitled to vote at such a meeting may call special meetings of stockholders.  If a special meeting is called by any person or persons other than the board of directors, the request shall be in writing, specifying the time of such meeting and the general nature of the business proposed to be transacted, and shall be delivered personally or sent by registered mail or by facsimile transmission to the chairman of the board, the president, the chief executive officer or the secretary of the corporation.  Nothing contained in this Section shall be construed as limiting, fixing, or affecting the time when a meeting of stockholders called by action of the board of directors may be held.

Section 2.2.  Business to be Transacted at Meetings.  At a meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting.  To be properly brought before a special meeting, business must be specified in the notice of the meeting (or any supplement thereto).  To be properly brought before an annual meeting, business must be (a) specified in the notice of the 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 stockholder.  For business to be properly brought before an annual meeting by a stockholder, the stockholder must, in addition to any requirements imposed by federal securities law or other applicable laws, have given timely notice thereof in writing to the secretary of the corporation.  To be timely for an annual meeting, a stockholder’s notice must be delivered to or mailed and received at the principal executive offices of the corporation, no later than (i) if the corporation mailed notice of the last annual meeting or publicly disclosed the date of such meeting and the annual meeting for the current year has not changed more than thirty days from such date (as if in the current year), forty-five days before the earlier of the date (as if in the current year) of such mailing or public disclosure or (ii) otherwise ninety days prior to the annual meeting.  A stockholder’s notice to the secretary with regard to an annual meeting shall set forth as to each order of business that the stockholder proposes to bring before the meeting (a) a brief description of such business desired to be brought before the meeting and the reasons for conducting such business at the annual meeting, (b) the name and address, as they appear on the corporation’s books, of the stockholder proposing such business, (c) the class and number of shares of the corporation that are beneficially owned by the stockholder and (d) any material interest of the stockholder in such business.  The chairman of the meeting may refuse to bring before a meeting any business not properly brought before the meeting in compliance with this section.

Section 2.3.  Notice.  Notice of the time, place and means of remote communication of an annual meeting of stockholders and notice of the time, place, means of remote communication and purpose or purposes of a special meeting of the stockholders shall be given not less than 10, nor more than 60, days prior to the meeting to each stockholder of record of the corporation entitled to vote at such meeting.  If mailed, such notice shall be deemed to be delivered when deposited in the United States mail, postage paid, addressed to the stockholder’s address appearing on the corporate books of the corporation.

Section 2.4.   Notice by Electronic Transmission.  Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the corporation under any applicable law, the certificate of incorporation or these bylaws shall be effective if given by a form of electronic transmission consented to by the stockholder to whom the notice is given.  Any such consent shall be revocable by the stockholder by written notice to the corporation.  Notice by electronic transmission shall be deemed given:  (a) if by facsimile telecommunication, when directed to a number at which the stockholder has consented to receive notice; (b) if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice; (c) if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon the later of (i) such posting and (ii) the giving of such separate notice; and (d) if by any other form of electronic transmission, when directed to the stockholder.

Section 2.5.  List of Stockholders.  The officer or agent having charge of the stock transfer books of the corporation shall make, at least 10 days before every meeting of the stockholders, a complete list of the stockholders entitled to vote at such meeting arranged in alphabetical order, specifying 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 for a period of at least 10 days prior to the meeting on a reasonably accessible electronic network or, during ordinary business hours, at the principal place of business of the corporation.  The list shall also be produced and kept at the time and place of the meeting during the whole time thereof and may be inspected by any stockholder who is present.  If the meeting of stockholders is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.  The original stock transfer books shall be the only evidence as to who are the stockholders entitled to examine such list or transfer book or to vote at any such meeting of stockholders.

Section 2.6.  Quorum.  The holders of a majority of the votes entitled to be cast at any meeting of stockholders, counted as a single class if there be more than one class of stock entitled to vote at such meeting, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders except as otherwise provided by statute or by the certificate of incorporation.  Once a quorum is present at a meeting of the stockholders, the stockholders represented in person or by proxy at the meeting may conduct such business as may be properly brought before the meeting until it is adjourned, and the subsequent withdrawal from the meeting by any stockholder or the refusal of any stockholder represented in person or by proxy to vote shall not affect the presence of a quorum at the meeting.  If a quorum is not present, the chairman of the meeting or the holders of the shares present in person or represented by proxy at the meeting, and entitled to vote thereat, shall have the power, by the affirmative vote of the holders of a majority of such shares, to adjourn the meeting to another time and/or place.  Unless the adjournment is for more than thirty days or unless a new record date is set for the adjourned meeting, no notice of the adjourned meeting need be given to any stockholder provided that the time and place of the adjourned meeting were announced at the meeting at which the adjournment was taken.  At the adjourned meeting the corporation may transact any business that might have been transacted at the original meeting.

Section 2.7.  Proxies.  Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for him by proxy.  A telegram, telex, cablegram or reliable electronic transmission executed or duly authorized by the stockholder, or a photographic, photostatic, facsimile or reliable reproduction of a writing executed or duly authorized by the stockholder shall be treated as an execution in writing for purposes of this section.  No proxy shall be valid after three years from the date of its execution unless otherwise provided in the proxy.  Each proxy shall be revocable unless the proxy form conspicuously states that the proxy is irrevocable and the proxy is coupled with an interest.

Section 2.8.  Order of Business.  The order of business at each such stockholders meeting shall be as determined by the chairman of the meeting. One of the following persons, in the order in which they are listed (and in the absence of the first, the next, and so on), shall serve as chairman of the meeting:  the chairman of the board, vice chairman of the board, president, the chief executive officer, vice presidents (in the order of their seniority if more than one) and secretary. The chairman of the meeting shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts and things as are necessary or desirable for the proper conduct of the meeting, including, without limitation, the establishment of procedures for the maintenance of order and safety, limitations on the time allotted to questions or comments on the affairs of the corporation, restrictions on entry to such meeting after the time prescribed for the commencement thereof, and the opening and closing of the voting polls.

Section 2.9.  Appointment of Inspectors of Election.  The board of directors shall appoint one or more inspectors of election (“inspectors”) to act at such meeting or any adjournment or postponement thereof and make a written report thereof.  The board of directors may designate one or more persons as alternate inspectors to replace any inspector who fails to act.  If no inspector or alternate is so appointed or if no inspector or alternate is able to act, the chairman of the board, the vice chairman of the board, the president or the chief executive officer shall appoint one or more inspectors to act at such 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.  The inspectors may be directors, officers or employees of the corporation.

Section 2.10.  Confidential Voting.  All proxies, ballots and vote tabulations that identify the particular vote of a stockholder shall be kept confidential, except that disclosure may be made (a) to allow the inspectors to certify the results of the vote; (b) as necessary to meet applicable legal requirements, including the pursuit or defense of judicial actions; or (c) when expressly requested by such stockholder.  Nothing in this section shall prohibit the inspector from making available to the corporation, during the period prior to any annual or special meeting, information as to which stockholders have not voted and periodic status reports on the aggregate vote.

Section 2.11.  Action Without a Meeting.

(a) Any action to be taken at a meeting of the stockholders, may be taken without a meeting, without prior notice, and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holder or holders of shares having not less than the minimum number of votes that would be necessary to take such action at a meeting at which the holders of all shares entitled to vote on the action were present and voted.

(b) Every written consent of the stockholders shall bear the date of signature of each stockholder who signs the consent.  No written consent shall be effective to take the action that is the subject of the consent unless, within 60 days after the date of the earliest dated consent delivered to the corporation as provided below, a consent or consents signed by the holder or holders of shares having not less than the minimum number of votes that would be necessary to take the action that is the subject of the consent are delivered to the corporation by delivery to its registered office, its principal place of business, or an officer or agent of the corporation having custody of the books in which proceedings of meetings of the stockholders are recorded.  Such delivery shall be made by hand or by certified or registered mail, return receipt requested, and in the case of delivery to the corporation’s principal place of business, shall be addressed to the president or chief executive officer of the corporation.

(c) Without limitation, a telegram, cablegram or electronic transmission by a stockholder, or a photographic, photostatic, facsimile or other reliable reproduction of a writing signed or transmitted by a stockholder, shall be regarded as signed by the stockholder for the purposes of this section.

(d) Prompt notice of the taking of any action by stockholders without a meeting by less than unanimous written consent shall be given to those stockholders who did not consent in writing to the action and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for such meeting had been the date that written consents signed by a sufficient number of holders to take the action were delivered to the corporation.

Section 2.12.  Fixing A Record Date.  In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or entitled 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.  With respect to corporate action in writing without a meeting, such record date shall not precede the date upon which the resolution fixing the record date is adopted by the board of directors nor more than 10 days after the date upon which the resolution fixing the record date is adopted by the board of directors.  With respect to any other action, such record date shall not precede the date upon which the resolution fixing the record date is adopted nor more than 60 days prior to such action.

If the board of directors does not so fix a record date:

(a) The record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders 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 stockholders entitled to express consent to corporate action in writing without a meeting, when no prior action by the board of directors is required under the laws of the state of Delaware, shall be the first date on which a signed written consent is delivered to the corporation in accordance with the requirements of such law.

(c) The record date for determining stockholders 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 stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the board of directors may fix a new record date for the adjourned meeting.

Section 2.13.  Remote Communications.  If authorized by the board of directors in its sole discretion, and subject to such guidelines and procedures as the board of directors may adopt, stockholders and proxyholders not physically present at a meeting of stockholders may, by means of remote communication, (a) participate in a meeting of stockholders, and (b) be deemed present in person and vote at a meeting of stockholders whether such meeting is to be held at a designated place or solely by means of remote communication, provided that (i) the corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a stockholder or proxyholder, (ii) the corporation shall implement reasonable measures to provide such stockholders and proxyholders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (iii) if any stockholder or proxyholder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the corporation.

Section 2.14.  Minutes.  The stockholders shall cause regular minutes of their proceedings to be kept, and such minutes shall be placed in the minute proceedings of the corporation (which may be maintained in paper or electronic form).

Section 5.3.  Expenses of Contested Indemnification Claims.  If a claimant makes a claim on the corporation under Section 5.1 or 5.2 and the corporation does not pay such claim in full within thirty days after it has received such written claim, 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 also be entitled to be paid also the expenses of prosecuting such claim.  It shall be a defense to any such action that such indemnification of advancement of costs of defense are not permitted under the General Corporation Law of Delaware or other applicable law, but the burden of proving such defense shall be on the corporation.  Neither the failure of the corporation (including its board of directors or any committee thereof, special legal counsel or stockholders) to have made its determination prior to the commencement of such action that indemnification of, or advancement of costs of defense to, the claimant is permissible in the circumstances nor an actual determination by the corporation (including its board of directors or any committee thereof, special legal counsel, or stockholders) that such indemnification or advancement is not permissible, shall be a defense to the action or create a presumption that such indemnification or advancement is not permissible.

Section 5.4.  Indemnification Not Exclusive.  The indemnification and advancement of expenses provided by, or granted pursuant to, this Article shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any other bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office.

Section 5.5.  Survival of Indemnification and Advancement of Expenses.  The indemnification and advancement of expenses provided by, or granted pursuant to, this Article shall 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 person.

Section 5.6.  Employees, Agents and Others.  To the fullest extent of Delaware law, the corporation may grant rights of indemnification and advancement of expenses to any person who is not at the time a current director or officer of the corporation.

Section 5.7.  Contract Right.  Each of the rights of indemnification and advancement of expenses provided by, or granted pursuant to, this Article shall be a contract right that will survive the termination of any person’s service as a director or officer and any repeal or amendment of the provisions of this Article shall not adversely affect any such right of any person existing at the time of such repeal or amendment with respect to any act or omission occurring prior to the time of such repeal or amendment, and further, shall not apply to any proceeding, irrespective of when the proceeding is initiated, arising from the service of such person prior to such repeal or amendment.

Section 5.8.  Insurance.  To the fullest extent of Delaware law, the corporation shall have power to purchase and maintain insurance on behalf of any person, including one who is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another 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 to indemnify him or her against such liability under the provisions of this Article or Delaware law.

Section 5.9.  Certain References Under Article V.  For purposes of this Article, references to “the corporation,” “other enterprise” and “serving at the request of the corporation” shall have the meanings given such terms in Section 145 of the Delaware General Corporation Law or any successor or similar statute.  As used herein, the term “proceeding” means any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative, any appeal in such an action, suit or proceeding, and any inquiry or investigation that could lead to such an action, suit or proceeding.

Section 6.2.  Transfers.  Transfers of stock shall be made only upon the transfer books of the corporation or respective transfer agents designated to transfer the several classes of stock and, in the case of shares represented by a certificate or certificates, upon the surrender of a properly endorsed certificate or certificates for a like number of shares.

Section 6.3.  Lost or Destroyed Certificates.  The corporation may issue a new stock certificate in place of any certificate theretofore issued by it, alleged to have been lost, stolen or destroyed, and the corporation shall, except as otherwise determined by the board of directors, the chairman of the board, the president, the chief executive officer any vice president or other authorized officer, require the owner of the lost, stolen or destroyed certificate, or his or her legal representative, to give the corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate.

Section 6.4.  Registered Stockholders.  The corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends, and to vote as such owner, and to hold liable for calls and assessments a person registered on its books as the owner of shares, and shall not be bound to recognize any equitable or other claim to or interest in such shares on the part of another person, whether or not the corporation shall have express or other notice thereof, except as otherwise provided by the laws of the state of Delaware.

Section 6.5.  Restrictions on Transfers of Shares.  Notice of any restriction on the transfer of shares of the corporation’s stock shall be placed on each certificate of stock issued, or in the case of uncertificated shares, contained in the notice sent to the registered holder of such shares in accordance with the laws of the state of Delaware.
