Notice of the time, place, if any, and purpose of any meeting of stockholders may be waived by a writing signed by the person entitled to notice thereof, or by electronic transmission by such person, either before or after such meeting, and will be waived by any stockholder by such stockholder’s attendance thereat in person, by remote communication, if applicable, or by proxy, except when the stockholder attends a meeting 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. Any stockholder so waiving notice of such meeting shall be bound by the proceedings of such meeting in all respects as if due notice thereof had been given. Neither the business to be transacted at nor the purpose of the meeting needs to be specified in a waiver of notice.

Section 3.5    Quorum. At all meetings of stockholders, except where otherwise provided by law or by the Certificate of Incorporation or by these Bylaws, the presence, in person, by remote communication, if applicable, or by proxy duly authorized, of the holders of a majority in voting power of the outstanding shares of stock entitled to vote at the meeting shall constitute a quorum for the transaction of business. In the absence of a quorum, any meeting of stockholders may be adjourned, from time to time, by the chairman of the meeting or by a majority in voting power of the stockholders present, but no other business shall be transacted at such meeting. A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of stockholders, if any action taken is approved by at least a majority of the required quorum for that meeting.

Section 3.6    Voting. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, the affirmative vote of a majority in voting power of shares present in person, by remote communication, if applicable, or represented by proxy at the meeting and entitled to vote generally on the subject matter shall be the act of the stockholders. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, directors shall be elected by the affirmative vote of the holders of a majority of the voting power of the then outstanding shares of Common Stock. Voting at meetings of stockholders need not be by written ballot.

Section 3.7    Adjournment and Notice of Adjourned Meetings. Any meeting of stockholders, whether annual or special, may be adjourned from time to time by the chairman of the meeting or by a majority in voting power of the stockholders present.

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 thirty (30) days or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting satisfying the requirements set forth in Section 3.4 of these Bylaws shall be given to each stockholder of record entitled to vote at the meeting.

Section 3.8    Voting Rights. For the purpose of determining those stockholders entitled to vote at any meeting of the stockholders, except as otherwise provided by law, only persons in whose names shares stand on the stock records of the Corporation on the record date, as provided in Section 3.10 of these Bylaws, shall be entitled to vote at any meeting of stockholders. Every person entitled to vote shall have the right to do so either in person, by remote communication, if applicable, or by an agent or agents authorized by a proxy granted in accordance with Delaware law. An agent so appointed need not be a stockholder. No proxy shall be voted or acted upon after three (3) years from its date unless the proxy provides for a longer period. A proxy shall be irrevocable if it states that it is irrevocable and if, and so long as, it is coupled with an interest sufficient in law to support an irrevocable power. A stockholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by delivering to the Secretary of the Corporation a revocation of the proxy or a new proxy bearing a later date.

Section 3.9    Stockholder Action Without a Meeting. Unless otherwise restricted in the Certificate of Incorporation, any action required to be taken at any annual or special meeting of stockholders of the Corporation, or any action which may be taken at any annual or special meeting of such 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 holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders

who have not consented in writing 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 as provided above.

Any copy, facsimile or other reliable reproduction of a consent in writing may be substituted or used in lieu of the original writing for any and all purposes for which the original writing could be used; provided that such copy, facsimile or other reproduction shall be a complete reproduction of the entire original writing.

The Secretary shall prepare and make available, at least ten (10) 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 each stockholder and the number of shares registered in the name of each stockholder. The Corporation shall not be required to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of at least ten (10) days prior to the meeting, at the discretion of the Corporation (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.

Section 7.2    Lost Certificates. A new certificate or certificates may be issued in place of any certificate or certificates theretofore 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. The Corporation may require, as a condition precedent to the issuance of a new certificate or certificates, the owner of such lost, stolen, or destroyed certificate or certificates, or such owner’s legal representative, to give the Corporation a surety bond in such form and amount as it may direct as indemnity against any claim that may be made against the Corporation with respect to the certificate alleged to have been lost, stolen, or destroyed.

Section 7.3    Fixing Record Dates. In order that the Corporation may determine the stockholders (a) entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, (b) to express consent to corporate action in writing without a meeting, (c) to receive payment of any dividend or other distribution or allotment of any rights, (d) to exercise any rights in respect of any change, conversion or exchange of stock or (e) for the purpose of any other lawful action, 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 by the Board of Directors, and which record date: (i) in the case of determination of stockholders entitled to vote at any meeting of stockholders or adjournment thereof, shall, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting; (ii) in the case of determination of stockholders entitled to express consent to corporate

action in writing without a meeting, shall not be more than ten (10) days from the date upon which the resolution fixing the record date is adopted by the Board of Directors; and (iii) in the case of any other action, shall not be more than sixty (60) days prior to such other action. 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; (2) the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting, when no prior action of the Board of Directors is required by law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation in accordance with applicable law, or, if prior action by the Board of Directors is required by law, shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action; and (3) 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 7.4    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 shall not be bound to recognize any equitable or other claim to or interest in such share or shares 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.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 11.1    Right to Indemnification. The Corporation shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended or revised, any person (a “Covered Person”) who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”), by reason of the fact that he or she, or a person for whom he or she is the executor, administrator or other legal representative, 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, agent or manager of another corporation or of a partnership, limited liability company, joint venture, trust, enterprise or nonprofit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys’ fees) reasonably incurred by such Covered Person. Notwithstanding the preceding sentence, except as otherwise provided in this Article XI, the Corporation shall be required to indemnify a Covered Person in connection with a proceeding (or part thereof) commenced by such Covered Person only if the commencement of such proceeding (or part thereof) by the Covered Person was authorized in the specific case by the Board of the Corporation.

Section 11.2.    Prepayment of Expenses. The Corporation shall, to the fullest extent not prohibited by applicable law, pay the expenses (including attorneys’ fees) incurred by a Covered Person in defending any proceeding in advance of its final disposition; provided, however, that, to the extent required by law, such payment of expenses in advance of the final disposition of the proceeding shall be made only upon receipt of an undertaking by the Covered Person to repay all amounts advanced if it should be ultimately determined that the Covered Person is not entitled to be indemnified under this Article XI or otherwise.

14

Section 11.3    Claims. If a claim for indemnification (following the final disposition of such action, suit or proceeding) or advancement of expenses under this Article XI is not paid in full within thirty (30) days after a written claim therefor by the Covered Person has been received by the Corporation, the Covered Person may file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such suit to the fullest extent permitted by law. In any such action the Corporation shall have the burden of proving that the Covered Person is not entitled to the requested indemnification and/or advancement of expenses under applicable law.

Section 11.4    Nonexclusivity of Rights. The rights conferred on any Covered Person by this Article XI shall not be exclusive of any other rights which such Covered Person may have or hereafter acquire under any law, the Certificate of Incorporation, these Bylaws, agreement, vote of stockholders or disinterested directors, or otherwise.

Section 11.5.    Other Sources. The Corporation’s obligation, if any, to indemnify or to advance expenses to any Covered Person who was or is serving at its request as a director, officer, employee, agent or manager of another corporation, partnership, limited liability company, joint venture, trust, enterprise or nonprofit entity shall be reduced by any amount such Covered Person may collect as indemnification or advancement of expenses from such other corporation, partnership, limited liability company, joint venture, trust, enterprise or non-profit enterprise.

Section 11.6.    Amendment, Modification or Repeal. The provisions of this Article XI shall constitute a contract between the Corporation, on the one hand, and, on the other hand, each individual who serves or has served as a director or officer of the Corporation (whether before or after the adoption of this Article XI), in consideration of such person’s past or current and any future performance of services for the Corporation, and pursuant to this Article XI the Corporation intends to be legally bound to each such current or former director or officer of the Corporation. With respect to current and former directors or officers of the Corporation, the rights conferred under this Article XI are present contractual rights, and such rights are fully vested, and shall be deemed to have vested fully, immediately upon adoption of this by-law. With respect to any directors or officers of the Corporation who commence service following adoption of this Bylaw, the rights conferred under this provision shall be present contractual rights, and such rights shall fully vest, and be deemed to have vested fully, immediately upon such director or officer commencing service as a director or officer of the Corporation. Neither amendment nor alteration nor repeal nor modification (whether by merger, consolidation, or otherwise) of any provision of this Article XI nor the adoption of any provision of the Certificate of Incorporation inconsistent with this Article XI shall eliminate or reduce the effect of this Article XI in respect of any act or omission occurring, or any cause of action or claim that accrues or arises or any state of facts existing, at the time of or before such amendment, alteration, repeal, modification or adoption of an inconsistent provision (even in the case of a proceeding based on such a state of facts that is commenced after such time). The rights to indemnification and to advancement of expenses provided by, or granted pursuant to, this Article XI shall continue notwithstanding that the person has ceased to be a director or officer of the Corporation and shall inure to the benefit of the estate, heirs, executors, administrators, legatees and distributes of such person.

15

Section 11.7    Other Indemnification and Prepayment of Expenses. This Article XI shall not limit the right of the Corporation, to the extent and in the manner permitted by law, to indemnify and to advance expenses to persons other than Covered Persons when and as authorized by appropriate corporate action.

Section 11.8    Insurance. The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was a director or officer of the Corporation or was serving at the request of the Corporation as a director, officer, employee, agent or manager of another corporation or of a partnership, limited liability company, joint venture, trust, enterprise or nonprofit entity against any liability asserted against him or her and incurred by him or her in any such capacity, whether or not the Corporation would have the power to indemnify such person against such liability under this Article XI.

ARTICLE XII

NOTICES

Section 12.1    Notices.

(a)    Notice to Stockholders. Whenever notice is required to be given to any stockholder under any provisions of these Bylaws, the Certificate of Incorporation or pursuant to the DGCL, such notice shall be given in writing and may be sent by U.S. mail or by facsimile, telegraph or telex or by electronic mail or other applicable electronic means consented to by such stockholder in accordance with Section 232 of the DGCL. If notice is given by U.S. mail, it shall be sent postage prepaid and addressed to such stockholder’s last known post office address as shown by the stock record of the Corporation. Notwithstanding the foregoing, written notice to stockholders for purposes other than stockholder meetings may also be sent by nationally recognized overnight courier, addressed to such stockholder’s last known post office address as shown by the stock record of the Corporation.

(b)    Notice to Directors. Any notice required to be given to any director may be given by the method stated in subsection (a) of this Section 12.1, as otherwise provided in these Bylaws, or by overnight delivery service, facsimile, telex, telegram or by electronic mail, except that such notice other than one which is delivered personally shall be sent to such address as such director shall have filed in writing with the Secretary, or, in the absence of such filing, to the last known post office address of such director.

(c)    Affidavit of Notice. An affidavit of notice, executed by a duly authorized and competent employee of the Corporation, specifying the name and address or the names and addresses of the stockholder or stockholders, or director or directors, to whom any such notice or notices was or were given, and the time and method of giving the same, shall in the absence of fraud, be prima facie evidence of the facts therein contained.

(d)    Time Notices Deemed Given. All notices given by mail, as above provided, shall be deemed to have been given as of the time of mailing, and all notices given by facsimile, telex, telegram or by electronic mail shall be deemed to have been given as of the sending time recorded at time of transmission or, if applicable, as of the time set forth in Section 232 of the DGCL.

16

(e)    Methods of Notice. It shall not be necessary that the same method of giving notice be employed in respect of all directors or stockholders, 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.

(f)    Failure to Receive Notice. Subject to applicable law, 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 to such stockholder in the manner above provided, shall not be affected or extended in any manner by the failure of such stockholder or such director to receive such notice if the giving of such notice complied with this Section 12.1.

(g)    Notice to Person with Undeliverable Address. Whenever notice is required to be given, under any provision of law or the Certificate of Incorporation or Bylaws of the Corporation, to any stockholder to whom (i) notice of two consecutive annual meetings, and all notices of meetings or of the taking of action by written consent without a meeting to such person during the period between such two consecutive annual meetings, or (ii) all, and at least two (2), payments (if sent by first class mail) of dividends or interest on securities during a twelve-month period, have been mailed addressed to such person at his or her address as shown on the records of the Corporation and have been returned undeliverable, the giving of such notice to such person shall not be required; provided, that the mailing of such notices and/or payments, as applicable, complied with these Bylaws. Any action or meeting which shall be taken or held without notice to such person shall have the same force and effect as if such notice had been duly given. If any such person shall deliver to the Corporation a written notice setting forth his or her then current address, the requirement that notice be given to such person shall be reinstated. 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 DGCL, the certificate need not state that notice was not given to persons to whom notice was not required to be given pursuant to this paragraph. Notwithstanding the foregoing, this Bylaw shall not apply to notice given by means of electronic transmission.

ARTICLE XIII

These Bylaws may be altered or amended or new Bylaws adopted by the affirmative vote of at least a majority of the voting power of all of the then-outstanding shares of the Common Stock.
