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.

Notwithstanding the foregoing provisions of this 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 Company to present a nomination or other business, such nomination shall be disregarded and such proposed other business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Company. For purposes of this by-law, 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.

Nothing in this by-law shall be deemed to affect any rights (i) of stockholders to request inclusion of proposals in the Company’s proxy statement pursuant to applicable rules and regulations under the Exchange Act or (ii) of the holders of any series of Preferred Stock of the Company to elect directors under specified circumstances.

(5)Notwithstanding the foregoing provisions of this Section 8, unless otherwise required by law, (i) no Proposing Person shall solicit proxies in support of director nominees other than the Company’s nominees unless such Proposing Person has complied with Rule 14a-19 promulgated under the Exchange Act in connection with the solicitation of such proxies, including the provision to the Company of notices required thereunder in a timely manner and (ii) if any Proposing Person (1) provides notice pursuant to Rule 14a-19(b) promulgated under the Exchange Act and (2) subsequently fails to comply with the requirements of Rule 14a-19(a)(2) and Rule 14a-19(a)(3) promulgated under the Exchange Act, including the provision to the Company of notices required thereunder in a timely manner, or fails to timely provide reasonable evidence sufficient to satisfy the Company that such Proposing Person has met the requirements of Rule 14a-19(a)(3) promulgated under the Exchange Act in accordance with the following sentence, then the Company shall disregard any proxies or votes solicited for the Proposing Person’s candidates.

Exhibit 3.1

Section 10.Business and Order of Business. At each meeting of the stockholders such business may be transacted as may properly be brought before such meeting, except as otherwise provided by law or in these By-Laws. The order of business at all meetings of the stockholders shall be as determined by the chairman of the meeting, unless otherwise determined by a majority in interest of the stockholders present in person or by proxy at such meeting and entitled to vote thereat.

Section 11.Voting. Except as otherwise provided by law, the Certificate of Incorporation or these By-Laws, each stockholder shall at every meeting of the stockholders be entitled to one vote for each share of stock held by such stockholder. Any vote of share of stock may be given by the stockholder entitled thereto in person or by proxy appointed by an instrument in writing, subscribed (or transmitted by electronic means and authenticated as provided by law) by such stockholder or by the stockholder’s attorney thereunto authorized, and delivered to the Secretary; provided, however, that no proxy shall be voted after three years from its date unless the proxy provides for a longer period. A proxy may be in the form of a telegram, cablegram or other means of electronic transmission which sets forth or is submitted with information from which it can be determined that the telegram, cablegram or other means of electronic transmission was authorized by the stockholder. Except as otherwise provided by law, the Certificate of Incorporation or these By-Laws, at all meetings of the stockholders, all matters shall be decided by the affirmative vote (which need not be by ballot) of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) on such matter.

Any stockholder directly or indirectly soliciting proxies from other stockholders must use a proxy card color other than white, which shall be reserved for the exclusive use by the Board of Directors.

Section 12.Inspectors of Election. The Company may, and shall if required by-law, in advance of any meeting of stockholders, appoint one or more inspectors of election, who may be employees of the Company, to act at the meeting or any adjournment thereof and to make a written report thereof. The Company may designate one or more persons as alternate inspectors to replace any inspector who fails to act. In the event that no inspector so appointed or designated 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 to execute faithfully the duties of inspector with strict impartiality and according to the best of his or her ability. The inspector or inspectors so appointed or designated shall (i) ascertain the number of shares of capital stock of the Company outstanding and the voting power of each such share, (ii) determine the shares of capital stock of the Company represented at the meeting and the validity of proxies and ballots, (iii) count all

Exhibit 3.1

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 of capital stock of the Company represented at the meeting and such inspectors’ count of all votes and ballots. Such certification and report shall specify such other information as may be required by-law. In determining the validity and counting of proxies and ballots cast at any meeting of stockholders of the Company, the inspectors may consider such information as is permitted by applicable law. No person who is a candidate for an office at an election may serve as an inspector at such election.

Section 13.Delivery to the Company. Whenever this Article II requires one or more persons (including a record or beneficial owner of stock) to deliver a document or information to the Company or any officer, employee or agent thereof (including any notice, request, questionnaire, revocation, representation or other document or agreement), such document or information shall be in writing exclusively (and not in an electronic transmission) and shall be delivered exclusively by hand (including, without limitation, overnight courier service) or by certified or registered mail, return receipt requested, and the Company shall not be required to accept delivery of any document not in such written form or so delivered.

If directors are to be elected by a plurality of the votes cast, stockholders shall not be permitted to vote against a nominee.

INDEMNIFICATION

Section 1.Proceedings Other Than Proceedings by or in the Right of the Company. The Company 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 the Company),

22

Exhibit 3.1

by reason of the fact that such person is or was a director, officer, employee or agent of the Company or any of its majority-owned subsidiaries or is or was serving at the request of the Company as a director, officer, employee or agent (except in each of the foregoing situations to the extent any written agreement, arrangement or understanding of agency to which such person is a party contains provisions that supersede or abrogate indemnification under this Section 1) of another corporation or of any partnership, joint venture, trust, employee benefit plan or other enterprise, against expenses (including attorneys’ fees), judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. 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 such person reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

Section 2.Proceedings by or in the Right of the Company. The Company 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 Company to procure a judgment in its favor by reason of the fact that such person is or was a director, officer, employee or agent of the Company or any of its majority-owned subsidiaries, or is or was serving at the request of the Company as a director, officer, employee or agent (except in each of the foregoing situations to the extent any written agreement, arrangement or understanding of agency to which such person is a party contains provisions that supersede or abrogate indemnification under this Section 2) of another corporation or of any partnership, joint venture, trust, employee benefit plan or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Company 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 to the Company unless and only to the extent that the Court of Chancery of Delaware 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 person is fairly and

23

Exhibit 3.1

reasonably entitled to indemnity for such expenses which the Court of Chancery of Delaware or such other court shall deem proper.

Section 3.Indemnification for Expenses of Person Who Is Wholly or Partly Successful. To the extent that a director, officer, employee or agent of the Company or any of its majority owned subsidiaries has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 1 or 2 of this Article VII, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by or on behalf of such person in connection therewith. If any such person is not wholly successful in any such action, suit or proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters therein, the Company shall indemnify such person against all expenses (including attorneys’ fees) actually and reasonably incurred by or on behalf of such person in connection with each claim, issue or matter that is successfully resolved. For purposes of this Article VII and without limitation, the termination of any claim, issue or matter by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

Section 4.Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Article VII, to the extent any person is a witness in, but not a party to, any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director, officer, employee or agent of the Company or any of its majority-owned subsidiaries, or is or was serving at the request of the Company as a director, officer, employee or agent (except in each of the foregoing situations to the extent any written agreement, arrangement or understanding of agency to which such person is a party contains provisions that supersede or abrogate indemnification under this Section 4) of another corporation or of any partnership, joint venture, trust, employee benefit plan or other enterprise, such person shall be indemnified against all expenses (including attorneys’ fees) actually and reasonably incurred by or on behalf of such person in connection therewith.

Section 5.Determination of Right to Indemnification. Indemnification under Sections 1 and 2 of this Article VII shall be made 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 such person has met the applicable standard of conduct set forth in Section 1 or 2 of this Article VII, as the case may be. Such determination shall be made (1) if a Change of Control (as hereinafter defined) shall not have occurred, (a) by the Board of Directors by a majority vote of the Disinterested Directors (as hereinafter defined), even though less than a quorum, or (b) if there are no Disinterested Directors or, even if there are Disinterested Directors, a majority of such Disinterested Directors so directs, by (x) Independent Counsel (as hereinafter

24

Exhibit 3.1

defined) in a written opinion to the Board of Directors, a copy of which shall be delivered to the claimant, or (y) if the Board of Directors so directs, the stockholders of the Company; or (2) if a Change of Control shall have occurred, by Independent Counsel selected by the claimant in a written opinion to the Board of Directors, a copy of which shall be delivered to the claimant, unless the claimant shall request that such determination be made by or at the direction of the Board of Directors, in which case it shall be made in accordance with clause (1) of this sentence. Any claimant shall be entitled to be indemnified against the expenses (including attorneys’ fees) actually and reasonably incurred by such claimant in cooperating with the person or entity making the determination of entitlement to indemnification (irrespective of the determination as to the claimant’s entitlement to indemnification) and, to the extent successful, in connection with any litigation or arbitration with respect to such claim or the enforcement thereof.

Section 6.Timing of Determination of Right to Indemnification. If a Change of Control shall not have occurred, or if a Change of Control shall have occurred and a director, officer, employee or agent requests pursuant to clause (2) of the second sentence in Section 5 of this Article VII that the determination as to whether the claimant is entitled to indemnification be made by or at the direction of the Board of Directors, the claimant shall be conclusively presumed to have been determined pursuant to Section 5 of this Article VII to be entitled to indemnification if (a)(i) within fifteen days after the next regularly scheduled meeting of the Board of Directors following receipt by the Company of the request therefor, the Board of Directors shall not have resolved by majority vote of the Disinterested Directors to submit such determination to (x) Independent Counsel for its determination or (y) the stockholders for their determination at the next annual meeting, or any special meeting that may be held earlier, after such receipt, and (ii) within sixty days after receipt by the Company of the request therefor (or within ninety days after such receipt if the Board of Directors in good faith determines that additional time is required by it for the determination and, prior to expiration of such sixty-day period, notifies the claimant thereof), the Board of Directors shall not have made the determination by a majority vote of the Disinterested Directors, or (b) after a resolution of the Board of Directors, timely made pursuant to clause (a)(i)(y) above, to submit the determination to the stockholders, the stockholders meeting at which the determination is to be made shall not have been held on or before the date prescribed (or on or before a later date, not to exceed sixty days beyond the original date, to which such meeting may have been postponed or adjourned on good cause by the Board of Directors acting in good faith); provided, however, that this sentence shall not apply if the claimant has misstated or failed to state a material fact in connection with his or her request for indemnification. Such presumed determination that a claimant is entitled to indemnification shall be deemed to have been made (I) at the end of the sixty-day or ninety-day period (as the case may be) referred to in clause (a)(ii) of the immediately preceding sentence or (II) if the Board of Directors has resolved on a timely basis to submit the determination to the

25

Exhibit 3.1

stockholders, on the last date within the period prescribed by law for holding such stockholders meeting (or a postponement or adjournment thereof as permitted above).

Section 7.Advancement of Expenses. Expenses (including attorneys’ fees) incurred in defending a civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the Company, at the sole discretion of the Board of Directors, in advance of the final disposition of such action, suit or proceeding, promptly after receipt of a request therefor stating in reasonable detail the expenses incurred; provided that in each case the Company shall have received an undertaking by or on behalf of the present or former director, officer, employee or agent to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Company as authorized in this Article VII.

Section 8.Procedures. The Board of Directors may, from time to time, establish reasonable procedures for the submission of claims for indemnification pursuant to this Article VII, determination of the entitlement of any person thereto and review of any such determination.

Section 1.Shares of Stock. The shares of the stock of the Company shall be uncertificated shares, as approved by the Board of Directors.

Section 2.Record Ownership. A record of the name and address of each holder of the shares of the Company, the number of shares held by such stockholder and the date of issuance of the shares held by such stockholder shall be made on the Company’s books. The Company shall be entitled to treat the holder of record of any share of stock (including any holder registered in a book-entry or direct registration system maintained by the Company or a transfer agent or a registrar designated by the Board of Directors) as the holder in fact thereof and accordingly shall not be bound to recognize any equitable or other claim to or interest in such share on the part of any other person, whether or not it shall have express or other notice thereof, except as required by law.

Section 3.Transfer of Stock. Shares of stock shall be transferable on the books of the Company by the holder of record of such stock in person or by such person’s attorney or other duly constituted representative, pursuant to applicable law and such rules and regulations as the Board of Directors shall from time to time prescribe.

Section 4.Transfer Agent and Registrar; Regulations. The Company shall, if and whenever the Board of Directors shall so determine, maintain one or more transfer offices or agencies, each in charge of a transfer agent designated by the Board of Directors, where the shares of the stock of the Company shall be directly transferable, and also one or more registry

29

Exhibit 3.1

offices, each in charge of a registrar designated by the Board of Directors, where such shares of stock shall be registered. The Board of Directors may also make such additional rules and regulations as it may deem expedient concerning the issue, transfer and registration of shares of stock of the Company and concerning the registration of pledges of uncertificated shares.

Section 5.Fixing Record Date. For the purpose of determining the stockholders entitled to notice of any meeting of stockholders or any adjournment thereof, 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 sixty nor less than ten days before the date of such meeting, nor more than sixty days prior to any other action. If the Board of Directors so fixes a record date for any meeting of stockholders, such record date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed (1) 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 and (2) 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 6.Examination of Books by Stockholders. The Board of Directors shall, subject to the laws of the State of Delaware, have power to determine from time to time, whether and to what extent and under what conditions and regulations the accounts and books of the Company, or any of them, shall be open to the inspection of the stockholders; and no stockholder shall have any right to inspect any book or document of the Company, except as conferred by the laws of the State of Delaware, unless and until authorized so to do by resolution of the Board of Directors or of the stockholders of the Company.

Section 7.Dividends. The Board, in its discretion and subject to any restrictions contained in either (i) the Delaware General Corporation Law or (ii) the Certificate of Incorporation, may declare and pay dividends upon the shares of its capital stock. Dividends may be paid in cash, in property or in shares of the Company’s capital stock. The Board may set apart out of any of the funds of the Company available for dividends a reserve or reserves for any

30

Exhibit 3.1

proper purpose and may abolish any such reserve. Such purposes shall include but not be limited to equalizing dividends, repairing or maintaining any property of the Company, and meeting contingencies.

Article IX

NOTICE

Section 1.Manner of Giving Written Notice.

(A)Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice required by law or by these By-Laws to be given to any stockholder in writing directed to the stockholder’s mailing address (or by electronic transmission directed to the stockholder’s electronic mail address, as applicable) as it appears on the records of the Company and shall be effective if (1) if mailed, when the notice is deposited in the U.S. mail, postage prepaid, (2) if delivered by courier service, the earlier of when the notice is received or left at such stockholder’s address or (3) if given by electronic mail, when directed to such stockholder’s electronic mail address unless the stockholder has notified the Company in writing or by electronic transmission of an objection to receiving notice by electronic mail. A notice by electronic mail must include a prominent legend that the communication is an important notice regarding the Company. Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the Company under any provision of the Delaware General Corporation Law, the Certificate of Incorporation or these By-laws 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 or electronic transmission to the Company. Notwithstanding the provisions of this paragraph, the Company may give a notice by electronic mail in accordance with the first paragraph of this section without obtaining the consent required by this paragraph.

Any such consent shall be deemed revoked if (i) the Company is unable to deliver by electronic transmission two consecutive notices given by the Company in accordance with such consent and (ii) such inability becomes known to the Secretary or an Assistant Secretary of the Company or to the transfer agent, or other person responsible for the giving of notice; provided, however, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action. An affidavit of the Secretary or an Assistant Secretary or of the transfer agent or other agent of the Company that the

31

Exhibit 3.1

notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(B)Notice by mail shall be deemed to be given at the time when the same shall be mailed and notice by other means shall be deemed given when actually delivered (and in the case of notice transmitted by a form of electronic transmission, such notice shall be deemed given (i) if by facsimile telecommunication, when directed to a number at which the stockholder has consented to receive notice; (ii) if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice; (iii) if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon the later of (A) such posting and (B) the giving of such separate notice; and (iv) if by any other form of electronic transmission, when directed to the stockholder).

Section 2.Waiver of Notice. Whenever any notice is required to be given to any person, a waiver thereof by such person in writing or transmitted by electronic means (and authenticated if and as required by law), whether before or after the time stated therein, shall be deemed equivalent thereto. Attendance of a person at any meeting shall constitute a waiver of notice of the meeting, unless the person attends for the express purpose of objecting, at the beginning of the meeting, to transacting any business the meeting because the meeting was not lawfully called or convened.

Article X

SEAL

The corporate seal, if any, shall have inscribed thereon the name of the Company, the year of its organization and the words “Corporate Seal” and “Delaware.”

Article XI

FISCAL YEAR

The fiscal year of the Company shall end on December 31 in each year.

Article XII

FORUM SELECTION

Unless the Company consents in writing to the selection of an alternative forum, (a) the Court of Chancery (the “Chancery Court”) of the State of Delaware (or, in the event that the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware

32

Exhibit 3.1

or other state courts of the State of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action, suit or proceeding brought on behalf of the Company, (ii) any action, suit or proceeding asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or to the Company’s stockholders, (iii) any action, suit or proceeding arising pursuant to any provision of the Delaware General Corporate Law or the Certificate of Incorporation or these By-Laws (as either may be amended from time to time), or (iv) any action, suit or proceeding asserting a claim against the Company governed by the internal affairs doctrine; and (b) subject to the preceding provisions of this Article XII, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause or causes of action arising under the Securities Act of 1933, as amended, including all causes of action asserted against any defendant to such complaint. If any action the subject matter of which is within the scope of clause (a) of the immediately preceding sentence is filed in a court other than a court located within the State of Delaware (a “Foreign Action”) in the name of any stockholder, such stockholder shall be deemed to have consented to (i) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce the provisions of clause (a) of the immediately preceding sentence and (ii) having service of process made upon such stockholder in any such action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder.

Any person or entity purchasing or otherwise acquiring any interest in any security of the Company shall be deemed to have notice of and consented to this Article XII. This provision is intended to benefit and may be enforced by the Company, its officers and directors, the underwriters to any offering giving rise to such complaint, and any other professional or entity whose profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying the offering. Notwithstanding the foregoing, the provisions of this Article XII shall not apply to suits brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts of the United States have exclusive jurisdiction.

If any provision or provisions of this Article XII shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever, (a) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article XII (including, without limitation, each portion of any paragraph of this Article XII containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (b) the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby.
