 BYLAWS 

OF 
 EXCO
HOLDING (PA), INC. 
 ARTICLE I  

OFFICES 

Section 1. Registered Office. The registered office of EXCO Holding (PA), Inc. (the “Corporation”) required
by the General Corporation Law of the State of Delaware (the “DGCL”) to be maintained in the State of Delaware, shall be the registered office named in the original Certificate of Incorporation of the Corporation (as the same may be
amended and restated from time to time, the “Certificate of Incorporation”), or such other office as may be designated from time to time by the Board of Directors in the manner provided by law. Should the Corporation maintain a
principal office within the State of Delaware such registered office need not be identical to such principal office of the Corporation. 

Section 2. Other Offices. The Corporation may have offices at such other places both within and without the State of Delaware
as the Board of Directors may from time to time determine or as the business of the Corporation may require. 
 ARTICLE II

 STOCKHOLDERS 

Section 1. Place of Meetings. All meetings of the stockholders shall be held at the principal office of the Corporation, or
at such other place within or without the State of Delaware as shall be specified or fixed in the notices or waivers of notice thereof. 

Section 2. Quorum; Adjournment of Meetings. Unless otherwise required by law or provided in the Certificate of Incorporation
or these bylaws, the holders of shares of stock with a majority of the voting power entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at any meeting of stockholders for the transaction of business and the
act of the holders of a majority of the voting power of such stock so represented at any meeting of stockholders at which a quorum is present shall constitute the act of the meeting of stockholders. The stockholders present at a duly organized
meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. Shares of its own stock belonging to the Corporation or to another corporation, if such shares of stock
represent a majority of the voting power entitled to vote in the election of directors of such other corporation are held, directly or indirectly, by the Corporation, shall neither be entitled to vote nor be counted for quorum purposes; provided,
however, that the foregoing shall not limit the right of the Corporation or any subsidiary of the Corporation to vote stock, including but not limited to its own stock, held by it in a fiduciary capacity. 

Notwithstanding the other provisions of the Certificate of Incorporation or these bylaws, the chairman of the meeting or the holders of
shares of stock with a majority of the voting power present in person or represented by proxy at any meeting of stockholders, whether or not a quorum is present, shall have the power to adjourn such meeting from time to time, without any

  

 1 

 
notice other than announcement at the meeting of the time and place of the holding of the adjourned meeting; provided, however, 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 shall be given to each stockholder of record entitled to vote at such meeting. At any such adjourned meeting at which a quorum shall be
present or represented any business may be transacted which might have been transacted at the meeting as originally called. 

Section 3. Annual Meetings. An annual meeting of the stockholders, for the election of directors to succeed those whose terms
expire and for the transaction of such other business as may properly come before the meeting, shall be held at such place, within or without the State of Delaware, on such date, and at such time as the Board of Directors shall fix and set forth in
the notice of the meeting, which date shall be within thirteen (13) months subsequent to the later of the date of incorporation or the last annual meeting of stockholders. 

Section 4. Special Meetings. Unless otherwise provided in the Certificate of Incorporation, special meetings of the
stockholders for any purpose or purposes may be called at any time by the Chairman of the Board (if any), by the chief executive officer or by a majority of the Board of Directors, or by a majority of the executive committee (if any), and shall be
called by the Chairman of the Board (if any), by the chief executive officer or the Secretary upon the written request therefor, stating the purpose or purposes of the meeting, delivered to such officer, signed by the holder(s) of at least ten
percent (10%) of the issued and outstanding stock entitled to vote at such meeting. 
 Section 5. Record Date.
For the purpose of determining stockholders entitled to notice of or to vote at any meeting of stockholders, or any adjournment thereof, or entitled to express consent to corporate action in writing without a meeting, or entitled to receive payment
of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors of the Corporation
may fix, in advance, a date as the record date for any such determination of stockholders, which date shall not be more than sixty (60) days nor less than ten (10) days before the date of such meeting, nor more than sixty (60) days
prior to any other action. 
 If the Board of Directors does not fix a record date for any meeting of the stockholders, the
record date for determining stockholders entitled to notice of or to vote at such meeting shall be at the close of business on the day next preceding the day on which notice is given, or, if in accordance with Article VIII,
Section 3 of these bylaws notice is waived, at the close of business on the day next preceding the day on which the meeting is held. If, in accordance with Section 12 of this Article II, corporate action without a
meeting of stockholders is to be taken, the record date for determining stockholders entitled to express consent to such corporate action in writing, when no prior action by the Board of Directors is necessary, shall be the day on which the first
written consent is expressed. 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. 

 

 2 

 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. Notice of Meetings. Written notice of the place, date and hour of all meetings, and, in case of a special meeting,
the purpose or purposes for which the meeting is called, shall be given by or at the direction of the Chairman of the Board (if any) or the chief executive officer, the Secretary or the other person(s) calling the meeting to each stockholder
entitled to vote thereat and shall be delivered not less than ten (10) nor more than sixty (60) days before the date of the meeting, personally, by electronic transmission or by mail. If mailed, notice is given when deposited in the United
States mail, postage prepaid, directed to the stockholder at his or her address as it appears on the records of the Corporation. The Corporation may provide stockholders with notice of a meeting by electronic transmission provided such stockholders
have consented to receiving electronic notice. 
 Section 7. Stock List. A complete list of stockholders entitled to
vote at any meeting of stockholders, arranged in alphabetical order for each class of stock and showing the address of each such stockholder and the number of shares registered in the name of such stockholder, 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, either on a reasonably accessible electronic network, provided that the information required to
gain access to the list is provided with the notice of the meeting, or during ordinary business hours, at the principal place of business of the Corporation. The stock list shall also be produced and kept at the time and place of the meeting during
the whole time thereof, and may be inspected by any stockholder who is present. If the meeting 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. 

Section 8. Proxies. Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to a
corporate action in writing without a meeting may authorize another person or persons to act for him by proxy. Proxies for use at any meeting of stockholders shall be filed with the Secretary, or such other officer as the Board of Directors may from
time to time determine by resolution, before or at the time of the meeting. All proxies shall be received and taken charge of and all ballots shall be received and canvassed by the secretary of the meeting who shall decide all questions touching
upon the qualification of voters, the validity of the proxies, and the acceptance or rejection of votes, unless an inspector or inspectors shall have been appointed by the chairman of the meeting, in which event such inspector or inspectors shall
decide all such questions. 
 No proxy shall be valid after three (3) years from its date, unless the proxy provides for a
longer period. Each proxy shall be revocable unless expressly provided therein to be irrevocable and coupled with an interest sufficient in law to support an irrevocable power. 

Should a proxy designate two or more persons to act as proxies, unless such instrument shall provide the contrary, a majority of such
persons present at any meeting at which their powers thereunder are to be exercised shall have and may exercise all the powers of voting or 

 

 3 

 
giving consents thereby conferred, or if only one be present, then such powers may be exercised by that one; or, if an even number attend and a majority do not agree on any particular issue, each
proxy so attending shall be entitled to exercise such powers in respect of the same portion of the shares as he or she is of the proxies representing such shares. 

Section 9. Voting; Elections; Inspectors. Unless otherwise required by law or provided in the Certificate of Incorporation,
each stockholder shall have one vote for each share of stock entitled to vote which is registered in his or her name on the record date for the meeting. Shares registered in the name of another corporation, domestic or foreign, may be voted by such
officer, agent or proxy as the bylaw (or comparable instrument) of such corporation may prescribe, or in the absence of such provision, as the Board of Directors (or comparable body) of such corporation may determine. Shares registered in the name
of a deceased person may be voted by his or her executor or administrator, either in person or by proxy. 
 All voting, except
as required by the Certificate of Incorporation or where otherwise required by law, may be by a voice vote; provided, however, that upon demand therefor by stockholders holding shares of stock representing a majority of the voting power present in
person or by proxy at any meeting a written ballot vote shall be taken. All elections for directors shall be by written ballot unless otherwise provided in the Certificate of Incorporation. Unless otherwise provided in the Certificate of
Incorporation or these bylaws, directors shall be elected by a plurality of the votes cast by the holders of shares of stock entitled to vote in the election of directors at a meeting of stockholders at which a quorum is present. All other elections
and questions presented to the stockholders at a meeting at which a quorum is present shall, unless otherwise provided by the Certificate of Incorporation, these by-laws, the rules or regulations of any stock exchange applicable to the Corporation,
or applicable law or pursuant to any regulation applicable to the Corporation or its securities, be decided by the affirmative vote of the holders of a majority in voting power of the shares of stock of the Corporation which are present in person or
by proxy and entitled to vote thereon. Every stock vote shall be taken by written ballots, each of which shall state the name of the stockholder or proxy voting and such other information as may be required under the procedure established for the
meeting. 
 At any meeting at which a vote is taken by ballots, the chairman of the meeting may appoint one or more inspectors,
each of whom shall subscribe an oath or affirmation to execute faithfully the duties of inspector at such meeting with strict impartiality and according to the best of his or her ability. Such inspector shall ascertain the number of shares of
capital stock of the Corporation outstanding and the voting power of each such share, determine the shares of capital stock of the Corporation represented at the meeting and the validity of proxies and ballots, count all votes and ballots, determine
and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspectors, and certify their determination of the number of shares of capital stock of the Corporation 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 Corporation, the inspectors may consider such information as is permitted by applicable law. The chairman of the meeting may appoint any person to serve as inspector, except no candidate for the office of director shall be appointed as an
inspector. 
  

 4 

 Unless otherwise provided in the Certificate of Incorporation, cumulative voting for the
election of directors shall be prohibited. 
 Section 10. Conduct of Meetings. The meetings of the stockholders
shall be presided over by the Chairman of the Board (if any), or if he or she is not present, by the chief executive officer, or if neither the Chairman of the Board (if any), nor chief executive officer is present, by a chairman elected at the
meeting. The Secretary of the Corporation, if present, shall act as secretary of such meetings, or if he or she is not present, an Assistant Secretary shall so act; if neither the Secretary nor an Assistant Secretary is present, then a secretary
shall be appointed by the chairman of the meeting. 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
seem to him in order. Unless the chairman of the meeting of stockholders shall otherwise determine, the order of business shall be as follows: 
  

	 	(a)	Calling of meeting to order. 

  

	 	(b)	Election of a chairman and the appointment of a secretary if necessary. 

  

	 	(c)	Presentation of proof of the due calling of the meeting. 

  

	 	(d)	Presentation and examination of proxies and determination of a quorum. 

  

	 	(e)	Reading and settlement of the minutes of the previous meeting. 

  

	 	(f)	Reports of officers and committees. 

  

	 	(g)	The election of directors if an annual meeting, or a meeting called for that purpose. 

 

	 	(h)	Unfinished business, 

  

	 	(i)	New business, 

  

	 	(j)	Adjournment. 

 Section 11.
Treasury Stock. The Corporation shall not vote, directly or indirectly, shares of its own stock owned by it or any other corporation, if a majority of shares entitled to vote in the election of directors of such other corporation is held,
directly or indirectly by the Corporation and such shares shall not be counted for quorum purposes. 
 Section 12.
Action Without Meeting. Unless otherwise provided in the Certificate of Incorporation, any action permitted or required by law, the Certificate of Incorporation or these bylaws to be taken at a meeting of stockholders, may be taken without a
meeting, without prior notice and without a vote, if a consent 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. Prompt notice of the taking of the corporate action without a meeting by less than a unanimous written consent shall be given by the Secretary to
those stockholders who have not consented in writing.

 ARTICLE III 

BOARD OF DIRECTORS 

Section 1. Power; Number; Term of Office. The business and affairs of the Corporation shall be managed by or under the
direction of the Board of Directors, and subject to the restrictions imposed by law or the Certificate of Incorporation, they may exercise all the powers of the Corporation. 

The number of directors of the Corporation shall be determined from time to time by resolution of the Board of Directors or by the
holders of a majority of the shares then entitled to vote, unless the Certificate of Incorporation fixes the number of directors, in which case a change in the number of directors shall be made only by amendment of the Certificate of Incorporation.
Each director shall hold office for the term for which he or she is elected, and until his or her successor shall have been elected and qualified or until his or her earlier death, resignation or removal. 

Unless otherwise provided in the Certificate of Incorporation, directors need not be stockholders or residents of the State of Delaware.

 Section 2. Quorum. Unless otherwise provided in the Certificate of Incorporation, a majority of the total number
of directors shall constitute a quorum for the transaction of business of the Board of Directors and the vote of a majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors. 

Section 3. Place of Meetings; Order of Business. The directors may hold their meetings and may have an office and keep the
books of the Corporation, except as otherwise provided by law, in such place or places, within or without the State of Delaware, as the Board of Directors may from time to time determine by resolution. At all meetings of the Board of Directors
business shall be transacted in such order as shall from time to time be determined by the Chairman of the Board (if any), or in his or her absence by the chief executive officer, or by resolution of the Board of Directors. 

Section 4. First Meeting. Each newly elected Board of Directors may hold its first meeting for the purpose of organization
and the transaction of business, if a quorum is present, immediately after and at the same place as the annual meeting of the stockholders. Notice of such meeting shall not be required. 

Section 5. Regular Meetings. Regular meetings of the Board of Directors shall be held at such times and places as shall be
designated from time to time by resolution of the Board of Directors. Notice of such regular meetings shall not be required. 

Section 6. Special Meetings. Special meetings of the Board of Directors may be called by the Chairman of the Board (if any),
the chief executive officer or, on the Written request of any two directors, by the Secretary, in each case on at least twenty-four (24) hours personal or written notice or on at least twenty-four (24) hours notice by electronic
transmission 
  

 6 

 
to each director. Such notice, or any waiver thereof pursuant to Article VIII, Section 3 hereof, need not state the purpose or purposes of such meeting, except as may otherwise
be required by law or provided for in the Certificate of Incorporation or these bylaws. 
 Section 7. Removal. Any
director or the entire Board of Directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors; provided that, unless the Certificate of Incorporation otherwise provides,
if the Board of Directors is classified, then the stockholders may effect such removal only for cause; and provided further that, if the Certificate of Incorporation expressly grants to stockholders the right to cumulate votes for the election of
directors and if less than the entire Board of Directors is to be removed, no director may be removed without cause if the votes cast against his or her removal would be sufficient to elect him or her if then cumulatively voted at an election of the
entire Board of Directors, or, if there be classes of directors, at an election of the class of directors of which such director is a part. 

Section 8. Vacancies; Increases in the Number of Directors. Unless otherwise provided in the Certificate of Incorporation,
vacancies and newly created directorships resulting from any increase in the authorized number of directors may be filled by a majority of the directors then in office (although less than a quorum), a sole remaining director or by the holders of a
majority of the shares then entitled to vote; and any director so chosen shall hold office until the next annual election and until his or her successor shall be duly elected and shall qualify, unless sooner displaced. 

If the directors of the Corporation are divided into classes, any directors elected to fill vacancies or newly created directorships
shall hold office until the next election of the class for which such directors shall have been chosen, and until their successors shall be duly elected and shall qualify. 

Section 9. Compensation. Unless otherwise restricted by the Certificate of Incorporation, the Board of Directors shall have
the authority to fix the compensation of directors. 
 Section 10. Action Without a Meeting; Telephone Conference
Meeting. Unless otherwise restricted by the Certificate of Incorporation, any action required or permitted to be taken at any meeting of the Board of Directors, or any committee designated by the Board of Directors, may be taken without a
meeting if all members of the Board of Directors 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 of Directors or committee. Such consent shall have the same force and effect as a unanimous vote at a meeting, and may be stated as such in any document or instrument filed with the Secretary of State of Delaware.

 Unless otherwise restricted by the Certificate of Incorporation, subject to the requirement for notice of meetings, members
of the Board of Directors, or members of any committee designated by the Board of Directors, may participate in a meeting of such Board of Directors or committee, as the case may be, by means of a conference telephone or other communications
equipment by means of which all persons participating in the meeting can hear each other, and 
  

 7 

 
participation in such a meeting shall constitute presence in person at such meeting, except where a person participates in the meeting for the express purpose of objecting to the transaction of
any business on the ground that the meeting is not lawfully called or convened. 
 Section 11. Approval or Ratification
of Acts or Contracts by Stockholders. The Board of Directors in its discretion may submit any act or contract for approval or ratification at any annual meeting of the stockholders, or at any special meeting of the stockholders called for the
purpose of considering any such act or contract, and any act or contract that shall be approved or be ratified by the vote of the holders of shares of stock representing a majority of the voting power entitled to vote and present in person or by
proxy at such meeting (provided that a quorum is present), shall be as valid and as binding upon the Corporation and upon all the stockholders as if it has been approved or ratified by every stockholder of the Corporation. In addition, any such act
or contract may be approved or ratified by the written consent of the holders of shares of stock representing a majority of the voting power entitled to vote and such consent shall be as valid and as binding upon the Corporation and upon all the
stockholders as if it had been approved or ratified by every stockholder of the Corporation. 
 ARTICLE IV 

COMMITTEES 

Section 1. Designation; Powers. The Board of Directors may, by resolution passed by a majority of the whole board, designate
one or more committees, including, if they shall so determine, an executive committee, each such committee to consist of one or more of the directors of the Corporation. Any such designated committee shall have and may exercise such of the powers
and authority of the Board of Directors in the management of the business and affairs of the Corporation as may be provided in such resolution, except that no such committee shall have the power or authority of the Board of Directors in reference to
amending the Certificate of Incorporation, adopting an agreement of merger or consolidation, recommending to the stockholders an agreement of merger, 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 a dissolution of the Corporation, or amending, altering or repealing the bylaws or adopting new bylaws for the Corporation

seal of the Corporation to be affixed to all papers which may require it. In addition to the above, such committee or committees shall have such other powers and limitations of authority as may be determined from time to time by resolution adopted
by the Board of Directors.

place or places as may be provided by such rules, or by resolution of such committee or resolution of the Board of Directors. At every meeting of any such committee, the presence of a majority of all the members thereof shall constitute a quorum and
the affirmative vote of a majority of the members present shall be necessary for the adoption by it of any resolution. 
  

 8 

 Section 3. Substitution of Members. The Board of Directors may designate one or
more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of such committee. In the absence or disqualification of a member of a committee, the member or members present at any meeting and
not disqualified from voting, whether or not constituting a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of the absent or disqualified member.

ARTICLE VI 

INDEMNIFICATION OF DIRECTORS. OFFICERS, EMPLOYEES AND AGENTS 

Section 1. Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is
involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she or a person of whom he or she is the legal representative is or was or
has agreed to become a director or officer of the Corporation or is or was serving or has agreed to serve 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 employee benefit plans, 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 or having agreed to serve as a
director or officer, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the Delaware General Corporation Law, 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 said law permitted the Corporation to provide prior to such amendment) against all expense, liability and loss (including without limitation,
attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who
has ceased to serve in the capacity which initially entitled such person to indemnity hereunder and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that the Corporation shall indemnify any such person
seeking indemnification in connection with a proceeding (or part thereof), other than a proceeding (or part thereof) brought under Section 3 of this Article VI initiated by such person or his or her heirs, executors and
administrators only if such proceeding (or part thereof) was authorized by the board of directors of the Corporation. The right to indemnification conferred in this Article VI shall be a contract right and shall include the right to be paid by the
Corporation the expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that, if the Delaware General Corporation Law requires, the payment of such expenses incurred by a current, former or proposed
director or officer in his or her capacity as a director or officer or proposed director or 
  

 11 

 
officer (and not in any other capacity in which service was or is or has been agreed to be rendered by such person while a director or officer, including, without limitation, service to an
employee benefit plan) in advance of the final disposition of a proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such indemnified person, to repay all amounts so advanced if it shall ultimately be
determined that such indemnified person is not entitled to be indemnified under this Section or otherwise. 
 Section 2.
Indemnification of Employees and Agents. The Corporation may, by action of its Board of Directors, provide indemnification to employees and agents of the Corporation, individually or as a group, with the same scope and effect as the
indemnification of directors and officers provided for in this Article VI. 
 Section 3. Right of Claimant to
Bring Suit. If a written claim received by the Corporation from or on behalf of an indemnified party under this Article VI is not paid in full by the Corporation within ninety days after such receipt, the claimant may at any time
thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such
action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant
has not met the standards of conduct which make it permissible under the Delaware General Corporation Law for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation.
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 Delaware General Corporation Law, 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 4. Nonexclusivity of Rights. The right to indemnification and the advancement and payment of expenses conferred in
this Article VI shall not be exclusive of any other right which any person may have or hereafter acquire under any law (common or statutory), provision of the Certificate of Incorporation of the Corporation, bylaw, agreement, vote of
stockholders or disinterested directors or otherwise. 
 Section 5. Insurance. The Corporation may maintain
insurance, at its expense, to protect itself and any person who is or was serving as 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, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the
Delaware General Corporation Law. 
  

 12 

 Section 6. Savings Clause. If this Article VI or any portion hereof shall
be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify and hold harmless each director and officer of the Corporation, as to costs, charges and expenses (including attorneys’
fees), judgments, fines, and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative to the full extent permitted by any applicable portion of this Article VI that shall not
have been invalidated and to the fullest extent permitted by applicable law. Any repeal or modification of the foregoing provisions of this Article VI shall not adversely affect any right or protection hereunder of any Covered Person in
respect of any act or omission occurring prior to the time of such repeal or modification. 
 Section 7.
Definitions. For purposes of this Article, reference to the “Corporation” shall include, in addition to the Corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger
prior to (or, in the case of an entity specifically designated in a resolution of the Board of Directors, after) the adoption hereof and which, if its separate existence had continued, would have had the power and authority to indemnify its
directors, officers and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article with respect to the resulting or surviving corporation as he or she would have
with respect to such constituent corporation if its separate existence had continued. 
 ARTICLE VII  

CAPITAL STOCK 

Section 1. Certificates of Stock. Except as provided in this Section 1 of Article VI, the certificates for shares of the
capital stock of the Corporation shall be in such form, not inconsistent with that required by law and the Certificate of Incorporation, as shall be approved by the Board of Directors. The Chairman of the Board (if any), chief executive officer or a
Vice President shall cause to be issued to each stockholder one or more certificates, under the seal of the Corporation or a facsimile thereof if the Board of Directors shall have provided for such seal, and signed by the Chairman of the Board (if
any), chief executive officer or a Vice President and the Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer certifying the number of shares (and, if the stock of the Corporation shall be divided into classes or series,
the class and series of such shares) owned by such stockholder in the Corporation; provided, however, that any of or all the signatures on the certificate may be facsimile. The stock record books and the blank stock certificate books shall be kept
by the Secretary, or at the office of such transfer agent or transfer agents as the Board of Directors may from time to time by resolution determine. In case any officer, transfer agent or registrar who shall have signed or whose facsimile signature
or signatures shall have been placed upon any such certificate or certificates shall have ceased to be such officer, transfer agent or registrar before such certificate is issued by the Corporation, such certificate may nevertheless be issued by the
Corporation with the same effect as if such person were such officer, transfer agent or registrar at the date of issue. The stock certificates shall be consecutively numbered and shall be entered in the books of the Corporation as they are issued
and shall exhibit the holder’s name and number of shares. The Board of Directors may deem that any outstanding shares of the Corporation will be uncertificated and registered in such form on the stock books of the Corporation. 

 

 13 

 Section 2. Transfer of Shares. Subject to the provisions of the Certificate of
Incorporation regarding the transfer of stock, the shares of stock of the Corporation shall be transferable only on the books of the Corporation by the holders thereof in person or by their duly authorized attorneys or legal representatives upon
surrender and cancellation of certificates for a like number of shares. Subject to the provisions of the Certificate of Incorporation regarding the transfer of stock, upon surrender to the Corporation or a transfer agent of the Corporation of a
certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate
and record the transaction upon its books. 
 Section 3. Ownership of Shares. The Corporation shall be entitled to
treat the holder of record of any share or shares of capital stock of the Corporation 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 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. 

Section 4. Regulations Regarding Certificates. The Board of Directors shall have the power and authority to make all such
rules and regulations as they may deem expedient concerning the issue, transfer and registration or the replacement of certificates for shares of capital stock of the Corporation. 

Section 5. Lost or Destroyed Certificates. The Board of Directors may determine the conditions upon which a new certificate
of stock may be issued in place of a certificate which is alleged to have been lost, stolen or destroyed; and may, in their discretion, require the owner of such certificate or his or her legal representative to give bond, with sufficient surety, to
indemnify the Corporation and each transfer agent and registrar against any and all losses or claims which may arise by reason of the issue of a new certificate in the place of the one so lost, stolen or destroyed. 

ARTICLE VIII 

MISCELLANEOUS PROVISIONS 

Section 1. Fiscal Year. The fiscal year of the Corporation shall be such as established from time to time by the Board of
Directors. 
 Section 2. Corporate Seal. The Board of Directors may provide a suitable seal, containing the name of
the Corporation. The Secretary shall have charge of the seal (if any). If and when so directed by the Board of Directors or a committee thereof, duplicates of the seal may be kept and used by the Treasurer or by the Assistant Secretary or Assistant
Treasurer. 
 Section 3. Notice and Waiver of Notice. Whenever any notice is required to be given by law, the
Certificate of Incorporation or under the provisions of these bylaws, said notice shall be deemed to be sufficient if given by electronic transmission or by deposit of the same in a post office box in a sealed prepaid wrapper addressed to the person
entitled thereto at his or her post office address, as it appears on the records of the Corporation, and such notice shall be deemed to have been given on the day of such transmission or mailing, as the case may be. 

 

 14 

 Whenever notice is required to be given by law, the Certificate of Incorporation or under
any of the provisions of these bylaws, a written waiver thereof, signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any
business on the grounds that the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders, directors, or members of a committee of directors need be
specified in any written waiver of notice unless so required by the Certificate of Incorporation or these bylaws. 

Section 4. Resignations. Any director, member of a committee or officer may resign at any time. Such resignation shall be
made in writing or by electronic transmission and shall take effect at the time specified therein, or if no time be specified, at the time of its receipt by the chief executive officer or Secretary. The acceptance of a resignation shall not be
necessary to make it effective, unless expressly so provided in the resignation. 
 Section 5. Facsimile Signatures.
In addition to the provisions for the use of facsimile signatures elsewhere specifically authorized in these bylaws, facsimile signatures of any officer or officers of the Corporation may be used whenever and as authorized by the Board of Directors.

 Section 6. Reliance upon Books, Reports and Records. Each director and each member of any committee designated by
the Board of Directors shall, in the performance of his or her duties, be fully protected in relying in good faith upon the books of account or reports made to the Corporation by any of its officers, or by an independent certified public accountant,
or by an appraiser selected with reasonable care by the Board of Directors or by any such committee, or in relying in good faith upon other records of the Corporation. 

Section 7. Form of Records. Any records maintained by the Corporation in the regular course of its business, including its
stock ledger, books of account, and minute books, may be kept on, or by means of, or be in the form of, any information storage device or method, provided that the records so kept can be converted into clearly legible paper form within a reasonable
time. 
 ARTICLE IX 

AMENDMENTS 

If provided in the Certificate of Incorporation of the Corporation, the Board of Directors shall have the power to adopt, amend and
repeal from time to time bylaws of the Corporation, subject to the right of the stockholders entitled to vote with respect thereto to amend or repeal such bylaws as adopted or amended by the Board of Directors.
