ARTICLE I

(the “ Corporation ”) may have an office or offices other than its registered office at such place or places, either within or outside the State of Delaware, as the Board of Directors of the Corporation (the “ Board of Directors ”) may from time to time determine or the business of the Corporation may require.

ARTICLE II

MEETINGS OF STOCKHOLDERS

Section 1. Place of Meetings . The Board of Directors may designate a place, if any, either within or outside the State of Delaware, as the place of meeting for any annual meeting or for any special meeting.

Section 2. Annual Meeting . An annual meeting of the stockholders shall be held each year at such time as is specified by the Board of Directors. At the annual meeting, stockholders shall elect directors and transact such other business as properly may be brought before the annual meeting pursuant to Section 11 of ARTICLE II.

Section 3. Special Meetings . Special meetings of the stockholders may only be called in the manner provided in the Corporation’s certificate of incorporation as then in effect (the “ Certificate of Incorporation ”). Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice.

Section 4. Notice of Meetings . Notice of the place, if any, date, and time of all meetings of the stockholders, the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, and the record date for determining the stockholders entitled to vote at the meeting, if such date is different from the record date for determining stockholders entitled to notice of the meeting, shall be given, not less than 10 nor more than 60 days before the date on which the meeting is to be held, to each stockholder entitled to vote at such meeting as of the record date for determining the stockholders entitled to notice of the meeting, except as otherwise provided herein or required by law (meaning, here and hereinafter, as required from time to time by the General Corporation Law of the State of Delaware (the “ DGCL ”) or the Certificate of Incorporation).

(a) Form of Notice. All such notices shall be delivered in writing or by a form of electronic transmission if receipt thereof has been consented to by the stockholder to whom the notice is given. If mailed, such notice shall be deemed given when deposited in the United States mail, postage prepaid, addressed to the stockholder at his, her or its address as the same appears on the records of the Corporation. If given by facsimile telecommunication, such notice shall be deemed given when directed to a number at which the stockholder has consented to receive notice by facsimile. Subject to the limitations of Section 4(c) of this ARTICLE II, if given by electronic transmission, such notice shall be deemed to be delivered: (i) by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice; (ii) if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon the later of (x) such posting and (y) the giving of such separate notice; and (iii) if by any other form of electronic transmission, when directed to the stockholder. An affidavit of the Secretary or an Assistant Secretary of the Corporation, the transfer agent of the Corporation or any other agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(b) Waiver of Notice. Whenever notice is required to be given under any provisions of the DGCL, the Certificate of Incorporation, the certificate of designation relating to any outstanding class or series of preferred stock or these Third Amended and Restated Bylaws (the “ Bylaws ”), a written waiver thereof, signed by the stockholder entitled to notice, or a waiver by electronic transmission by the person or entity entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Neither the business to be transacted at, nor the purpose of, any meeting of the stockholders of the Corporation need be specified in any waiver of notice of such meeting. Attendance of a stockholder of the Corporation at a meeting of such stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened.

(c) Notice by Electronic Delivery . Without limiting the manner by which notice otherwise may be given effectively to stockholders of the Corporation pursuant to the DGCL, the Certificate of Incorporation, the certificate of designation relating to any outstanding class or series of preferred stock or these Bylaws, any notice to stockholders of the Corporation given by the Corporation under any provision of the DGCL, the Certificate of Incorporation or these Bylaws shall be effective if given by a form of electronic transmission consented to by the stockholder of the Corporation to whom the notice is given. Any such consent shall be deemed revoked if: (i) the Corporation is unable to deliver by electronic transmission two (2) consecutive notices given by the Corporation in accordance with such consent; and (ii) such inability becomes known to the Secretary or an Assistant Secretary of the Corporation or to the transfer agent or other person responsible for the giving of notice. However, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action. For purposes of these Bylaws, except as otherwise limited by applicable law, the term “electronic transmission” means any form of communication not directly involving the physical transmission of paper that creates a record that may be retained, retrieved and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such recipient through an automated process.

Section 5. List of Stockholders . The officer who has charge of the stock ledger of the Corporation shall prepare and make, at least 10 days before each meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting; provided, however, if the record date for determining the stockholders entitled to vote is less than 10 days before the meeting date, the list shall reflect the stockholders entitled to vote as of the 10th day before the meeting date, arranged in alphabetical order and showing the address of each such stockholder and the number of shares registered in his or her name. 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: (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (b) during ordinary business hours, at the principal place of business of the Corporation. In the event the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. The list shall also be produced and kept at the time and place, if any, of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

Section 6. Quorum . The holders of a majority of the outstanding voting power of capital stock entitled to vote, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders, except as otherwise provided by the DGCL or by the Certificate of Incorporation or the certificate of designation relating to any outstanding class or series of preferred stock. If a quorum is not present, the chairman of the meeting or the holders of a majority of the shares present in person or represented by proxy at the meeting and entitled to vote at the meeting may adjourn the meeting to another time and/or place. When a specified item of business requires a vote by a class or series (if the Corporation shall then have outstanding shares of more than one class or series) voting as a class or series, the holders of a majority of the voting power of such class or series shall constitute a quorum (as to such class or series) for the transaction of such item of business.

Section 7. Adjourned Meetings . When a meeting is adjourned to another time and place, notice need not be given of the adjourned meeting if the time and place, if any, thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 30 days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for stockholders entitled to vote is fixed for the adjourned meeting, the Board of Directors shall fix a new record date for notice of such adjourned meeting, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors and, except as otherwise required by law, shall not be more than 60 days nor less than 10 days before the date of such adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such adjourned meeting as of the record date fixed for notice of such adjourned meeting.

Section 8. Vote Required .

(a) In General. When a quorum is present, the affirmative vote of the majority of voting power of capital stock present in person or represented by proxy at the meeting and

- 3 -

entitled to vote on the subject matter shall be the act of the stockholders, unless by express provisions of an applicable law, the rules of any stock exchange upon which the Corporation’s securities are listed, the Certificate of Incorporation or the certificate of designation relating to any outstanding class or series of preferred stock a different vote is required, in which case such express provision shall govern and control the decision of such question.

(b) Election of Directors . When a quorum is present, a nominee for director shall be elected to the Board of Directors if the votes cast for such nominee’s election exceed the votes cast against such nominee’s election; provided, however , that directors shall be elected by a plurality of the votes cast at any meeting of stockholders for which (i) the Secretary of the Corporation receives a notice that a stockholder has nominated a person for the election to the Board of Directors in compliance with the advance notice requirements for stockholder nominees for director set forth in Section 11 of ARTICLE II of these Bylaws and (ii) such nomination has not been withdrawn by such stockholder on or prior to the tenth (10 ^th ) day preceding the date the Corporation first mails its notice of meeting for such meeting to the stockholders. If directors are to be elected by a plurality of the votes cast, stockholders shall not be permitted to vote against a nominee.

Section  9. Voting Rights . Except as otherwise provided by the DGCL, the Certificate of Incorporation, the certificate of designation relating to any outstanding class or series of preferred stock or these Bylaws, every stockholder shall at every meeting of the stockholders be entitled to one vote in person or by proxy for each share of capital stock held by such stockholder.

Section  10. Proxies . Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for him or her by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the Corporation generally.

The Corporation, or its designated transfer agent or other agent, shall keep a book or set of books to be known as the stock transfer books of the Corporation, containing the name of each holder of record, together with such holder’s address and the number and class or series of shares held by such holder and the date of issue. When shares are represented by certificates, the Corporation shall issue and deliver to each holder to whom such shares have been issued or transferred, certificates representing the shares owned by such holder, and shares of stock of the Corporation shall only be transferred on the books of the Corporation by the holder of record thereof or by such holder’s attorney duly authorized in writing, upon surrender to the Corporation or its designated transfer agent or other agent of the certificate or certificates for such shares endorsed by the appropriate person or persons, with such evidence of the authenticity of such endorsement, transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps. In that event, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate or certificates and record the transaction on its books. When shares are not represented by certificates, shares of stock of the Corporation shall only be transferred on the books of the Corporation by the holder of record thereof or by such holder’s attorney duly authorized in writing, with such evidence of the authenticity of such transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps, and within a reasonable time after the issuance or transfer of such shares, the Corporation shall send the holder to whom such shares have been issued or transferred a written statement of the information required by applicable law. Unless otherwise provided by applicable law, the Certificate of Incorporation, the certificate of designation relating to any outstanding class or series of preferred stock, these Bylaws or any other instrument, the rights and obligations of stockholders are identical, whether or not their shares are represented by certificates.

Section  2. Lost Certificates . The Corporation may issue or direct a new certificate or certificates or uncertificated shares to be issued in place of any certificate or certificates previously issued by the Corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen or destroyed. When authorizing such issue of a new certificate or certificates or uncertificated shares, the Corporation may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or his or her legal representative, to give the Corporation a bond in such sum as it may direct, sufficient to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate or uncertificated shares.

Section  3. Registered Stockholders . The Corporation shall be entitled to recognize the exclusive right of a person registered on its records as the owner of shares of stock to receive dividends, to vote, to receive notifications and otherwise to exercise all the rights and powers of an owner. The Corporation shall not be bound to recognize any equitable or other claim to or

- 19 -

interest in such share or shares of stock on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of the State of Delaware.

Section 4. Fixing a Record Date for Purposes Other Than Stockholder . In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment or any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purposes of any other lawful action (other than stockholder meetings which is expressly governed by Section 12 of ARTICLE II), the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

Before payment of any dividend, there may be set aside out of any funds of the Corporation available for dividends such sum or sums as the Board of Directors from time to time, in its absolute discretion, thinks proper as a reserve or reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the Corporation or for such other purpose as the Board of Directors may think conducive to the interests of the Corporation.

otherwise assist any officer or other employee of the Corporation or of its subsidiaries, including any officer or employee who is a director of the Corporation or its subsidiaries, whenever, in the judgment of the directors, such loan, guaranty or assistance may reasonably be expected to benefit the Corporation. The loan, guaranty or other assistance may be with or without interest, and may be unsecured, or secured in such manner as the Board of Directors shall approve, including, without limitation, a pledge of shares of stock of the Corporation.

ARTICLE VII

INDEMNIFICATION

Section 1. Right to Indemnification and Advancement . Each person who was or is made a party or is threatened to be made a party to or is otherwise involved (including involvement, without limitation, as a witness) in any actual or threatened action, suit or proceeding, whether civil, criminal, administrative or investigative (a “ proceeding ”), by reason of the fact that he or she is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (an “ indemnitee ”), whether the basis of such proceeding is alleged action in an official capacity as a director or officer or in any other capacity while serving as a director or officer, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than permitted prior thereto), against all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, excise taxes, penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators; provided, however, that, except as provided in this Section 1 of this ARTICLE VII with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation. The right to indemnification conferred in this Section 1 of this ARTICLE VII shall be a contract right. In addition to the right to indemnification conferred herein, an indemnitee shall also have the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition (an “ advance of expenses ”); provided, however, that if and to the extent that the DGCL requires, an advance of expenses incurred by an indemnitee in his or her capacity as a director or officer (and not in any capacity in which service was or is rendered by such indemnitee, including without limitation, service to an employee benefit plan) shall be made only upon delivery to the Corporation of an undertaking (an “ undertaking ”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such indemnitee is not entitled to be indemnified for such expenses under this Section 1 or otherwise. The Corporation may also, by action of its Board of Directors, provide indemnification and advancement to employees and agents of the Corporation.

Section 2. Procedure for Indemnification . Any indemnification of a director or officer of the Corporation or advance of expenses (including attoneys’ fees, costs and charges) under this Section 2 of this ARTICLE VII shall be made promptly, and in any event within forty-five days (or, in the case of an advance of expenses, twenty days, provided that the director or officer has delivered the undertaking contemplated by Section 1 of this ARTICLE VII if required), upon the written request of the director or officer. If the Corporation denies a written request for

- 22 -

indemnification or advance of expenses, in whole or in part, or if payment in full pursuant to such request is not made within forty-five days (or, in the case of an advance of expenses, twenty days, provided that the director or officer has delivered the undertaking contemplated by Section 1 of this ARTICLE VII if required), the right to indemnification or advances as granted by this ARTICLE VII shall be enforceable by the director or officer in any court of competent jurisdiction. Such person’s costs and expenses incurred in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation. It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of expenses where the undertaking required pursuant to Section 1 of this ARTICLE VII, if any, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of such defense shall be on the Corporation to the fullest extent permitted by law. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Section 3. Insurance . The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was or has agreed to become 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 corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss 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 such person against such expenses, liability or loss under the DGCL.

Section 4. Service for Subsidiaries . Any person serving as a director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture or other enterprise, at least 50% of whose equity interests are owned by the Corporation (a “ subsidiary ” for this ARTICLE VII) shall be conclusively presumed to be serving in such capacity at the request of the Corporation.

Section 5. Reliance . Persons who after the date of the adoption of this provision become or remain directors or officers of the Corporation or who, while a director or officer of the Corporation, become or remain a director, officer, employee or agent of a subsidiary, shall be conclusively presumed to have relied on the rights to indemnity, advance of expenses and other rights contained in this ARTICLE VII in entering into or continuing such service. The rights to indemnification and to the advance of expenses conferred in this ARTICLE VII shall apply to claims made against an indemnitee arising out of acts or omissions which occurred or occur both prior and subsequent to the adoption hereof. Any amendment, alteration or repeal of this ARTICLE VII that adversely affects any right of an indemnitee or its successors shall be prospective only and shall not limit, eliminate, or impair any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment or repeal.

- 23 -

Section 6. Non-Exclusivity of Rights . The rights to indemnification and to the advance of expenses conferred in this ARTICLE VII shall not be exclusive of any other right which any person may have or hereafter acquire under the Certificate of Incorporation, the certificate of designation relating to any outstanding class or series of preferred stock or under any statute, by-law, agreement, vote of stockholders or disinterested directors or otherwise.

Section 7. Savings Clause . If this ARTICLE VII or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify and advance expenses to each person entitled to indemnification under Section 1 as to all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, excise taxes, penalties and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such person and for which indemnification and advancement of expenses is available to such person pursuant to this ARTICLE VII to the fullest extent permitted by any applicable portion of this ARTICLE VII that shall not have been invalidated and to the fullest extent permitted by applicable law.

ARTICLE VIII

AMENDMENTS

These Bylaws may be amended, altered, changed or repealed or new Bylaws adopted only in accordance with Article Six of the Certificate of Incorporation.
