the board of directors may adopt, stockholders and proxy holders not physically present at a meeting of stockholders may, by means of remote communication: (i) participate in a meeting of stockholders; and (ii) 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 (A) 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 proxy holder, (B) the Corporation shall implement reasonable measures to provide such stockholders and proxy holders 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 (C) if any stockholder or proxy

At such annual meetings, the stockholders shall elect the members of the Board which shall be determined by a plurality of votes cast and transact such other business as may properly be brought
before the meetings.

2.3 Special Meetings. Special meetings of the stockholders, for any purpose or purposes, may,
unless otherwise prescribed by the statute or by the Certificate of Incorporation, be called by the Chairman of the Board or the President and shall be called by the President or Secretary at the request in writing of a majority of the Board or of
the holders of shares entitled to cast not less than ten percent (10%) of the votes at the meeting and by additional persons as may be provided in the Certificate of Incorporation or these Bylaws. Such request shall state the purpose or
purposes of the proposed meeting. Upon request in writing that a special meeting of stockholders be called for any proper purpose, directed to the Chairman of the Board of Directors, the President, the Chief Executive Officer, the Vice President or
the Secretary, by any person (other than the board of directors) entitled to call a special meeting of stockholders, the person forthwith shall cause notice to be given to the stockholders entitled to vote that a meeting will be held at a time
requested by the person or persons calling the meeting, such time not to be less than thirty-five (35), nor more than sixty (60), days after receipt of the request. Such request shall state the purpose or purposes of the proposed meeting.

2.4 Notice of Meetings. Written notice of stockholders meetings, stating the place, if any, date and time of the
meeting, the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, and the purpose or purposes for which the meeting is called, shall be given to each
stockholder entitled to vote at such meeting not less than ten (10), nor more than sixty (60), days prior to the meeting.

When a meeting is adjourned to another place, date or time, written notice need not be given of the adjourned meeting if the place, if
any, date and time thereof and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting at which the adjournment is
taken; provided, however, that if the date of any adjourned meeting is more than thirty (30) days after the date for which the meeting was originally noticed, or if a new record date is fixed for the adjourned meeting, written notice of the
place, date and time of the adjourned meeting shall be given in conformity herewith. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.

2.5 Business Matter of a Special Meeting. Business transacted at any special meeting of stockholders shall be limited to the
purposes stated in the notice.

2.6 List of Stockholders. The officer in charge of the stock ledger of the Corporation
or the transfer agent shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten
(10) days prior to the meeting: (i) 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

(ii) during ordinary business hours, at the principal place of business of the Corporation. In the event that 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. If the meeting is to be held at a place, then the list shall 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 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.

2.7 Organization and Conduct of Business. The Chairman of the Board or, in his or her absence, the President of the Corporation or, in their absence, such person as the Board may have designated
or, in the absence of such a person, such person as may be chosen by the holders of a majority of the shares entitled to vote who are present, in person or by proxy, shall call to order any meeting of the stockholders and act as Chairman of the
meeting. In the absence of the Secretary of the Corporation, the Secretary of the meeting shall be such person as the Chairman appoints.

The Chairman of any meeting of stockholders shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of discussion as seems
to him or her in order.

2.8 Quorum and Adjournments. Except where otherwise provided by law or in the Certificate of
Incorporation or these Bylaws, the holders of a majority of the stock issued and outstanding and entitled to vote, present in person or represented in proxy, shall constitute a quorum at all meetings of the stockholders. The stockholders present at
a duly called or held meeting at which a quorum is present may continue to do business until adjournment, notwithstanding the withdrawal of enough stockholders to have less than a quorum if any action taken (other than adjournment) is approved by at
least a majority of the shares required to constitute a quorum. At such adjourned meeting at which a quorum is present or represented, any business may be transacted which might have been transacted at the meeting as originally noticed. If, however,
a quorum shall not be present or represented at any meeting of the stockholders, the stockholders entitled to vote thereat who are present in person or represented by proxy shall have the power to adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present or represented.

2.9 Voting Rights.
Unless otherwise provided in the Certificate of Incorporation, each stockholder shall at every meeting of the stockholders be entitled to one vote in person or by proxy for each share of the capital stock having voting power held by such
stockholder.

2.10 Majority Vote. When a quorum is present at any meeting, the vote of the holders of a majority of the
stock having voting power present in person or represented by proxy shall decide any question brought before such meeting, unless the question is one upon which, by express provision of the statutes or of the Certificate of Incorporation or of these
Bylaws, a different vote is required, in which case such express provision shall govern and control the decision of such question.

2.11 Record Date. For purposes of determining the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or 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 to
exercise any rights in respect of any change, conversion, or exchange of stock or for the purpose of any lawful action, the Board may fix, in advance, a record date which shall not be more than sixty (60), nor less than ten (10), days prior to the
date of such meeting, nor more than sixty (60) days prior to the date of any other action. A determination of stockholders of record entitled to notice or to vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board may fix a new record date for the adjourned meeting.

If the Board does not so fix a record
date, (i) 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 business day next preceding the day on which notice is given or, if notice is waived,
at the close of business on the business day next preceding the day on which the meeting is held and (ii) the record date for any other purpose shall be the close of business at the Corporations principal office on the day on which the
Board adopts the resolution relating to such purpose.

2.12 Proxies. Every person entitled to vote for directors or on
any other matter shall have the right to do so either in person or by one or more agents authorized by a written proxy signed by the person and filed with the Secretary of the Corporation. A proxy shall be deemed signed if the stockholders
name is placed on the proxy (whether by manual signature, typewriting, telegraphic transmission, electronic transmission or otherwise) by the stockholder or the stockholders attorney-in-fact. A validly executed proxy which does not state that
it is irrevocable shall continue in full force and effect unless (a) revoked by the person executing it, before the vote pursuant to that proxy, by a writing delivered to the Corporation stating that the proxy is revoked or by a subsequent
proxy executed by the maker of the proxy, or by that persons attendance and vote at the meeting; or (b) written notice of the death or incapacity of the maker of that proxy is received by the Corporation before the vote pursuant to that
proxy is counted; provided, however, that no proxy shall be valid after the expiration of eleven months from the date of the proxy, unless otherwise provided in the proxy.

2.13 Inspectors of Election. Before any meeting of stockholders, the Board may appoint any person other than nominees for office to act as inspectors of election at the meeting or its adjournment.
If no inspectors of election are so appointed, the Chairman of the meeting may, and on the request of any stockholder or a stockholders proxy shall, appoint inspectors of election at the meeting. The number of inspectors shall be either
one (1) or three (3). If inspectors are appointed at a meeting on the request of one or more stockholders or proxies, the holders of a majority of shares or their proxies present at the meeting shall determine whether one (1) or
three (3) inspectors are to be appointed. If any person appointed as inspector fails to appear or fails or refuses to act, the Chairman of the meeting may, and upon the request of any stockholder or a stockholders proxy shall, appoint a
person to fill that vacancy.

2.14 Action Without Meeting by Written Consent. All actions required to be taken at any
annual or special meeting 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

registered office, its principal place of business, or an officer or agent of the corporation having custody of the book in which proceedings of meetings or stockholders are recorded. A telegram, cablegram or other electronic transmission consenting
to an action to be taken and transmitted by a stockholder or proxyholder, or by a person or persons authorized to act for a stockholder or proxyholder, shall be deemed to be written, signed and dated for the purposes of this Section to the extent
permitted by law. Any such consent shall be delivered in accordance with Section 228(d)(1) of the Delaware General Corporation Law.

ARTICLE 3

Directors

3.1 Number; Qualifications; Election. The authorized number of directors shall initially be not less than one (1) nor more
than fourteen (14), the exact number within such range to be determined by the Board, but no reduction in the number of directors shall have the effect of reducing the terms of office of any directors then in office. All directors shall be elected
at the annual meeting or at any special meeting of the stockholders, except as provided in Section 3.2 hereof, and each director so elected shall hold office until the next annual meeting or any special meeting, or until his successor is
elected and qualified, or until his earlier resignation or removal. Directors need not be stockholders.

3.2 Resignation
and Vacancies. A vacancy or vacancies in the Board shall be deemed to exist in the case of the death, resignation or removal of any director, or if the authorized number of directors is increased. Vacancies may be filled by a majority of the
remaining directors, though less than a quorum, or by a sole remaining director, unless otherwise provided in the Certificate of Incorporation. The stockholders may elect a director or directors at any time to fill any vacancy or vacancies not
filled by the directors. If the Board accepts the resignation of a director tendered to take effect at a future time, the Board shall have power to elect a successor to take office when the resignation is to become effective. If there are no
directors in office, then an election of directors may be held in the manner provided by statute.

3.3 Removal of
Directors. Unless otherwise restricted by statute, or by the Certificate of Incorporation or these Bylaws, any director or the entire Board may be removed, with or without cause, by the holders of at least a majority of the shares entitled to
vote at an election of directors.

3.4 Powers. The business of the Corporation shall be managed by or under the
direction of the Board which may exercise all such powers of the Corporation and do all such lawful acts and things which are not by statute or by the Certificate of Incorporation or by these Bylaws directed or required to be exercised or done by
the stockholders.

transaction of other business.

3.7 Regular Meetings. Regular meetings of the Board may be held without notice at such
time and place as may be determined from time to time by the Board.

3.8 Special Meetings. Special meetings of the
Board may be called by one-third (1/3) of directors then in office (rounded up to the nearest whole number) or by the Chairman of the Board or the President and shall be held at such place, and on such date, and at such time as they or he or
she shall fix. Except as otherwise required by statute, notice of each special meeting shall be given to each director, if by mail, when addressed to him or her at his or her residence or usual place of business, unless he or she shall have filed
with the Secretary a written request that notices intended for him or her be mailed to some other address, in which case it shall be mailed to the address designated in such request, on at least two (2) days notice prior to the time of
the meeting, or shall be sent to him or her at such place by telegram, radiogram or cablegram, or other electronic means, or delivered to him or her personally, not later than four (4) hours before the time the meeting is to be held. Unless
otherwise indicated in the notice thereof, any and all business may be transacted at a special meeting.

3.9 Quorum and
Adjournments. At all meetings of the Board, a majority of the total number of the whole Board shall constitute a quorum for the transaction of business, and the act of a majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board, except as may otherwise be specifically provided by law or by the Certificate of Incorporation. If a quorum is not present at any meeting of the Board, the directors present may adjourn the meeting from time to time,
without notice other than announcement at the meeting at which the adjournment is taken, until a quorum shall be present. A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of directors,
if any action taken is approved of by at least a majority of the required quorum for that meeting.

3.10 Action Without
Meeting. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board or of any committee thereof may be taken without a meeting, if all members of the
Board or committee, as the case may be, consent thereto in writing or by electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the Board or committee. Such
filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form.

3.11 Telephone Meetings. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any member of the Board or of any committee may participate in a meeting by means of
conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at the meeting.

3.12 Waiver of Notice. Notice of a meeting need not be given to any director who
signs a waiver of notice or provides a waiver by electronic transmission or a consent to holding the meeting or an approval of the minutes thereof, whether before or after the meeting, or who attends the meeting without protesting, either prior
thereto or at its commencement, the lack of notice to such director. All such waivers, consents and approvals or any waiver by electronic transmission shall be filed with the corporate records or made a part of the minutes of the meeting.

3.13 Fees and Compensation of Directors. Unless otherwise restricted by the Certificate of Incorporation or these
Bylaws, the Board shall have the authority to fix the compensation of directors. The directors may be paid their expenses, if any, of attendance at each meeting of the Board, and may be paid a fixed sum for attendance at each meeting of the Board or
a stated salary as director. No such payment shall preclude any director from serving the Corporation in any other capacity and receiving compensation therefor. Members of special or standing committees may be allowed like compensation for attending
committee meetings.

3.14 Rights of Inspection. Every director shall have the absolute right at any reasonable time to
inspect and copy all books, records and documents of every kind, and to inspect the physical properties of the Corporation and also of its subsidiary corporations, domestic or foreign. Such inspection by a director may be made in person or by agent
or attorney, and includes the right to copy and obtain extracts.

3.15 Action with Respect to Securities of Other
Corporations. Unless otherwise directed by the Board, the President or any officer of the Corporation authorized by the President shall have power to vote and otherwise act on behalf of the Corporation, in person or by proxy, at any meeting of
stockholders of or with respect to any action of stockholders of any other corporation in which this Corporation may hold securities and otherwise to exercise any and all rights and powers which this Corporation may possess by reason of its
ownership of securities in such other corporation.

ARTICLE 4

In the absence or disqualification of a member of a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not he or she or they constitute a quorum,

Section 151(a) of the General Corporation Law of Delaware, fix any of the preferences or rights of such shares relating to dividends, redemption, dissolution, any distribution of assets of the Corporation or the conversion into, or the exchange
of such shares for, shares of any other class or classes or any other series of the same or any other class or classes of stock of the Corporation), adopting an agreement of merger or consolidation, recommending to the stockholders the sale, lease
or exchange of all or substantially all of the Corporations property and assets, recommending to the stockholders a dissolution of the Corporation or a revocation of dissolution, removing or indemnifying directors or amending the Bylaws of the

Indemnification of Directors And Officers. The Corporation shall, to the maximum extent and in the manner permitted by the General Corporation Law of Delaware, indemnify each of its directors and officers against expenses (including
attorneys fees), judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding, arising by reason of the fact that such person is or was an agent of the Corporation. For purposes of this
Section 6.1, a director or officer of the Corporation includes any person (a) who is or was a director or officer of the Corporation, (b) who is or was serving at the request of the Corporation as a director or
officer of another corporation, partnership, joint venture, trust or other enterprise, or (c) who was a director or officer of a corporation which was a predecessor corporation of the Corporation or of another enterprise at the request of such
predecessor corporation; provided, however, that, except with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify any such director or officer in connection with a proceeding (or part thereof) initiated by
such director of officer only if such proceeding (or part thereof) was authorized by the Board.

6.2 Indemnification of
Others. The Corporation shall have the power, to the maximum extent and in the manner permitted by the General Corporation Law of Delaware, to indemnify each of its employees and agents (other than directors and officers) against expenses
(including attorneys fees), judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding, arising by reason of the fact that such person is or was an agent of the Corporation. For purposes
of this Section 6.2, an employee or agent of the Corporation (other than a director or officer) includes any person (a) who is or was an employee or agent of the Corporation, (b) who is or was serving at the
request of the Corporation as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise, or (c) who was an employee or agent of a corporation which was a predecessor corporation of the Corporation or of
another enterprise at the request of such predecessor corporation.

6.3 Payment Of Expenses In Advance. Expenses
incurred in defending any action or proceeding for which indemnification is required pursuant to Section 6.1 hereof, or for which indemnification is permitted pursuant to Section 6.2 hereof, following authorization thereof by the Board,
shall be paid by the Corporation in advance of the final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of the indemnified party to repay such amount, if it shall ultimately be determined that the indemnified
party is not entitled to be indemnified as authorized in this Article 6.

6.4 Indemnity Not Exclusive. The
indemnification provided by this Article 6 shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both
as to action in an official capacity and as to action in another capacity while holding such office, to the extent that such additional rights to indemnification are authorized in the Certificate of Incorporation.

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 the General Corporation Law of Delaware.

6.6 Conflicts. No indemnification or
advance shall be made under this Article 6, except where such indemnification or advance is mandated by law or the order, judgment or decree of any court of competent jurisdiction, in any circumstance where it appears:

an agreement in effect at the time of the accrual of the alleged cause of the action asserted in the proceeding in which the expenses were incurred or other amounts were paid, which prohibits or otherwise limits indemnification; or

require, and/or to give the Corporation a bond in such sum 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.
