MEETINGS 
 Section 1. Places of Meetings. All meetings of stockholders shall be held at such place or places within or
outside the State of Delaware as shall be designated from time to time by the Board of Directors, the Chairman of the Board, the Chief Executive Officer or the President, and stated in the notice of meeting or waiver of notice thereof, subject to
any provisions of law. Notwithstanding the foregoing, the Board of Directors may determine that the meeting shall not be held at any place, but may instead be held by means of remote communication. 

Section 2. Annual Meetings. If required by law, the Corporation shall hold a meeting of its stockholders each year for the
election of directors and the transaction of such other business as may properly come before the meeting at such date and time as may be designated by the Board of Directors, the Chairman of the Board, the Chief Executive Officer or the President.
Unless otherwise provided by law, the Certificate of Incorporation or these Bylaws, notice of the time and place (if any) of the annual meeting, and the means of remote communication (if any) by which stockholders and proxyholders may be deemed to
be present in person and vote at such meeting, shall be given to each stockholder entitled to vote at such meeting not less than 10 nor more than 60 days prior to the date of such meeting. The Corporation may postpone, reschedule or cancel any
annual meeting of stockholders previously scheduled. 
 Section 3. Special Meetings. Except as otherwise provided in the
Certificate of Incorporation, a special meeting of the stockholders of the Corporation may be called at any time by (a) the Chairman of the Board, (b) the Board of Directors or the Secretary of the Corporation pursuant to a resolution
adopted by a majority of the directors then in office or (c) if so provided in the Certificate of Incorporation, Denali (as such term is defined in the Certificate of Incorporation), but such special meeting may not be called by any other
person or persons. Notice of the date, time, place (if any), the means of remote communication (if any) by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, and the purpose or purposes for which such
special meeting is called shall be given to each stockholder entitled to vote at such

Certificate of Incorporation, no special meeting of stockholders called by Denali may be postponed, rescheduled or cancelled by the Corporation without the prior written consent of Denali. 

Section 4. Voting. At all meetings of stockholders, each stockholder shall be entitled to such number of votes, if any, for each
share of stock entitled to vote and held of record by such stockholder as may be fixed in the Certificate of Incorporation, subject to any powers, restrictions or qualifications set forth in the Certificate of Incorporation. If authorized by the
Board of Directors, and subject to such guidelines as the Board of Directors may adopt, stockholders and proxyholders not physically present at a meeting of stockholders may participate in a meeting of stockholders by means of remote communication
and be deemed present in person and vote at such meeting whether such meeting is held at a designated place or solely by means of remote communication, provided that (a) the Corporation implements 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 proxyholder, (b) the Corporation implements reasonable measures to provide such stockholders and proxyholders 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 proxyholder
votes or takes other action at the meeting by means of remote communication, a record of such vote or other action is maintained by the Corporation. 

Section 5. Proxies. Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act
for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. A proxy shall be irrevocable if it states that it is irrevocable and if, and only as long
as, it is coupled with an interest sufficient in law to support an irrevocable power. A stockholder may revoke any proxy which is not irrevocable by attending the meeting of stockholders 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 6. Quorum; Required Vote. Except as
otherwise provided by the Certificate of Incorporation, these Bylaws or law, at any annual or special meeting of stockholders, the holders of shares of stock representing a majority in voting power of the shares of stock outstanding and entitled to
vote at such meeting, present in person or represented by proxy at such meeting, shall constitute a quorum. If a separate vote by class or series or classes or series of stock is required with respect to any matter brought before any annual or
special meeting of stockholders, the holders of shares representing a majority in voting power of the shares of such class or series or classes or series outstanding and entitled to vote with respect to such matter, present in person or represented
by proxy at such meeting, shall constitute a quorum entitled to take action with respect to such vote on such matter. In the absence of a quorum, the chairman of the meeting or the stockholders so present, by a majority of the voting power thereof,
may adjourn the meeting from time to time in the manner provided in Section 11 of this Article II until a quorum is present. 

  
 2 








 When a quorum is present at any meeting, and except as set forth below in this Section 6,
the affirmative vote of the holders of shares of stock representing a majority in voting power of the shares present in person or represented by proxy at the meeting and entitled to vote on such matter shall decide such matter, unless such matter is
one upon which a different vote is required by express provision of the Certificate of Incorporation, these Bylaws or law, in which case such express provision shall govern. Except as otherwise required by the Certificate of Incorporation or law,
directors shall be elected at any meeting by a plurality of the votes cast of the shares present in person or represented by proxy at such meeting and entitled to vote on the election of directors. If a separate vote by a class or series or classes
or series of stock is required with respect to any matter brought before a meeting, such matter shall be decided by the affirmative vote of the holders of shares of such class or series or classes or series representing a majority in voting power of
the shares of such class or series or classes or series present in person or represented by proxy at such meeting and entitled to vote on such matter, unless such matter is one upon which a different vote is required by express provision of the
Certificate of Incorporation, these Bylaws or law, in which case such express provision shall govern. 
 Section 7. Inspectors of
Election. In advance of any meeting of stockholders, the Corporation may appoint, and if required by law shall appoint, one or more inspectors of election (“inspectors”), which inspector or inspectors may include individuals who serve
the Corporation in other capacities, including, without limitation, as officers, employees, agents or representatives of the Corporation, to act at a meeting of stockholders or any adjournment thereof and make a written report thereof. One or more
persons may be designated as alternative inspectors to replace any inspector who fails so to act. If no inspector or alternate has been appointed so to act, or if all inspectors or alternates who have been appointed are unable so to act, the
chairman of the meeting shall appoint one or more inspectors to act at such meeting. Each inspector, before discharging his duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to
the best of his ability. The inspector or inspectors so appointed or designated shall (a) ascertain the number of shares of stock of the Corporation outstanding and the voting power of each such share, (b) determine the shares of stock of
the Corporation represented at the meeting and the validity of proxies and ballots, (c) count all votes and ballots, (d) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination
by the inspectors and (e) certify the determination by such inspector or inspectors of the number of shares of stock of the Corporation represented at the meeting and the count by such inspector or inspectors of all votes and ballots. Such
certification and report shall specify such other information as may be required by law or as may be requested by the chairman of the meeting. In determining the validity and counting of proxies and ballots cast at any meeting of stockholders, the
inspectors may consider such information as is permitted by law. No person who is a candidate for an office at an election may serve as an inspector at such election. 

Section 8. List of Stockholders. At least 10 days before every meeting of stockholders, a complete list of the stockholders
entitled to vote at the meeting (or, if the record date for determining the stockholders entitled to vote at the meeting is less than 10 days before the meeting date, a complete list of the stockholders entitled to vote at the meeting as of the 10th
day before the meeting date), arranged in alphabetical order and showing the address and the number of shares registered in the name of each stockholder, shall be prepared by the officer who has charge of the stock ledger. Such list shall be open
for examination by any stockholder, for any purpose germane to the meeting, for a period of at least 10 days prior to the meeting as required by law. If the meeting is to be held at a place, such list shall be produced and kept at the time and place
of the meeting during the whole time of the meeting, and may be inspected by any stockholder who is present at such meeting. If the meeting is to be held solely by means of remote communication, such list shall also be open to the examination of any
stockholder during the whole time of the meeting on a reasonably accessible 

  
 3 








 
electronic network, and the information required to access such list shall be provided with the notice of the meeting. Except as otherwise provided by law, the stock ledger shall be the only
evidence as to persons who are the stockholders entitled to examine the list of stockholders or to vote in person or by proxy at the meeting. 

Section 9. Conduct of Meetings. The Chairman of the Board (when present) shall preside as chairman of the meeting at each meeting
of stockholders and shall ensure that all orders and resolutions of the stockholders are carried into effect. The Chairman of the Board may designate any other director or any officer or representative of the Corporation to act in his stead as
chairman of the meeting for any meeting of stockholders. The date and time of the opening and closing of the polls for each matter upon which the stockholders will vote at a meeting of stockholders shall be announced at the meeting by the chairman
of the meeting. To the extent not prohibited by law, the Board of Directors may adopt by resolution such rules and regulations for the conduct of the meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with such
rules and regulations as adopted by the Board of Directors, the chairman of the meeting shall have the right and authority to convene and (for any or no reason) to recess or adjourn such meeting and to prescribe such rules, regulations and
procedures and to do all such acts as, in the judgment of the chairman of the meeting, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the
chairman of the meeting, to the extent not prohibited by law, may include, without limitation, the following: (a) the establishment of an agenda or order of business for the meeting; (b) rules and procedures for maintaining order at the
meeting and the safety of those present at the meeting; (c) limitations on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as the
chairman of the meeting shall determine may attend or participate in the meeting; (d) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (e) limitations on the time allotted to questions or comments
by participants in the meeting. In addition to making any other determinations that may be appropriate to the conduct of the meeting, if the facts so warrant, the chairman of the meeting shall determine and declare to the meeting that a matter or
business was not properly brought before the meeting and, if the chairman of the meeting shall so determine and declare, any such matter or business not properly brought before the meeting shall not be transacted or considered. Unless and to the
extent determined by the Board of Directors or the chairman of the meeting, meetings of stockholders shall not be required to be held in accordance with the rules of parliamentary procedure.

connection with solicitations of proxies for, as applicable, the proposal and/or for the election of directors in an election contest pursuant to and in accordance with Section 14(a) of the
Exchange Act and the rules and regulations promulgated thereunder. The foregoing notice requirements of this Section 10 shall be deemed satisfied by a stockholder with respect to business other than a nomination of a person for election to the
Board of Directors if the stockholder has notified the Corporation of the stockholder’s intention to present a proposal at an annual meeting in compliance with applicable rules and regulations promulgated under the Exchange Act and such
stockholder’s proposal has been included in a proxy statement that has been prepared by the Corporation to solicit proxies for such annual meeting. The Corporation may require any proposed nominee to furnish such other information as it may
reasonably require to determine the eligibility of such proposed nominee to serve as a director of the Corporation. For purposes of the first annual meeting following the adoption of these Bylaws, the date of the first anniversary of the preceding
year’s annual meeting shall be deemed to be July 1, 2017. 
 (3) Notwithstanding anything in the second sentence of paragraph (a)(2)
of this Section 10 to the contrary, in the event that the number of directors to be elected to the Board of Directors at an annual meeting is increased effective after the time period for which nominations would otherwise be due under paragraph
(a)(2) of this Section 10 and there is no public announcement by the Corporation naming the nominees for the additional directorships at least 100 days prior to the first anniversary of the preceding year’s annual meeting, a
stockholder’s notice required by this Section 10 shall also be considered timely, but only with respect to nominees for the additional directorships, if such notice shall be delivered to the Secretary of the Corporation at the principal
executive offices of the Corporation not later than 5:00 p.m. Eastern Time on the 10th day following the day on which such public announcement is first made by the Corporation. 

(b) Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been
brought before the meeting pursuant to the Corporation’s notice of meeting. Nominations of persons for election to the Board of Directors may be made at a special meeting of stockholders at which directors are to be elected pursuant to the
Corporation’s notice of meeting only (i) by or at the direction of the Board of Directors or any committee thereof (or the stockholders pursuant to Article VI, Section B of the Certificate of Incorporation) or (ii) provided that the
Board of Directors (or the stockholders pursuant to Article VI, Section B of the Certificate of Incorporation) shall have determined that directors shall be elected at such meeting, by any stockholder of the Corporation who was a stockholder of
record at the time the notice provided for in paragraph (a)(2) of this Section 10 is delivered to the Secretary of the Corporation, who is entitled to vote at the meeting and on such election and who complies with the notice procedures set
forth in this Section 10. The proposal by stockholders of other business to be conducted at a special meeting of stockholders may be made only in accordance with Article VI, Section B of the Certificate of Incorporation. If the Corporation
calls a special meeting of stockholders for the purpose of electing one or more members to the Board of Directors, any such stockholder entitled to vote on such election of directors may nominate a person or persons (as the case may be) for such
election as specified in the Corporation’s notice of meeting, if the same stockholder’s notice as is required by paragraph (a)(2) of this Section 10 with respect to an annual meeting of stockholders shall be delivered to the Secretary
of the Corporation at the principal executive offices of the Corporation not earlier than the 120th day prior to such special meeting and not later than 5:00 p.m. Eastern Time on the later of the 90th day prior to such special meeting or the 10th
day following the day on which public announcement is first made by the Corporation of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting. In no event shall the public announcement of
an adjournment or postponement of a special meeting commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above.

(1) Except as otherwise expressly provided in any applicable rule or regulation promulgated under the Exchange Act, only such persons who are
nominated in accordance with the procedures set forth in this Section 10 shall be eligible to be elected at an annual or special meeting of stockholders of the Corporation to serve as directors and only such business shall be conducted at a
meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 10. Except as otherwise provided by law, the chairman of the meeting shall have the power and duty (i) to
determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth in this Section 10 (including whether the stockholder or beneficial
owner, if any, on whose behalf the nomination or proposal is made solicited (or is part of a group which solicited) or did not so solicit, as the case may be, proxies or votes in support of such stockholder’s nominee or proposal in compliance
with such stockholder’s representation as required by clause (iii)(F) of paragraph (a)(2) of this Section 10) and (ii) if any proposed nomination or business was not made or proposed in compliance with this Section 10, to declare
that such nomination shall be disregarded or that such proposed business shall not be transacted. Notwithstanding the foregoing provisions of this Section 10, unless otherwise required by law, if the stockholder (or a qualified representative
of the stockholder) does not appear at the annual or special meeting of stockholders of the Corporation to present a nomination or proposed business, such nomination shall be disregarded and such proposed business shall not be transacted,
notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Section 10, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager
or partner of such stockholder or must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders, and such person must
produce such writing or electronic transmission, or a reliable reproduction of such writing or electronic transmission, at the meeting of stockholders. 

(2) For purposes of this Section 10, “public announcement” shall include disclosure in a press release reported by the Dow
Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act and the rules and
regulations promulgated thereunder. 
 (3) Notwithstanding the foregoing provisions of this Section 10, a stockholder shall also
comply with all applicable requirements of the Exchange Act and the rules and regulations promulgated thereunder with respect to the matters set forth in this Section 10; provided that any references in these Bylaws to the Exchange Act or the
rules and regulations promulgated thereunder are not intended to, and shall not, limit any requirements applicable to nominations or proposals as to any other business to be considered pursuant to this Section 10, and compliance with this
Section 10 shall be the exclusive means for a stockholder to make nominations or submit other business (other than, as provided in the penultimate sentence of paragraph (a)(2) of this Section 10, business other than nominations brought
properly under and in compliance with Rule 14a-8 under the Exchange Act, as may be amended from time to time). Nothing in this Section 10 shall be deemed to affect any rights of (i) stockholders to request inclusion of proposals or
nominations in the Corporation’s proxy 

  
 7 








 
statement pursuant to applicable rules and regulations promulgated under the Exchange Act or (ii) the holders of any series of preferred stock of the Corporation to elect directors pursuant
to any applicable provisions of the Certificate of Incorporation. 
 (4) Notwithstanding anything to the contrary contained in this
Section 10, for so long as Denali has the right to call a special meeting pursuant to Article VI, Section B of the Certificate of Incorporation, Denali shall not be subject to the notice procedures set forth in paragraph (a)(2), (a)(3) or
(b) of this Section 10 with respect to any annual or special meeting of stockholders. 
 Section 11. Adjournments. Any
annual or special meeting of stockholders may be adjourned from time to time to reconvene at the same or some other place (if any), and, except as provided in the following sentence, notice need not be given of any such adjourned meeting if the time
and place (if any) thereof, and the means of remote communication (if any) by which stockholders and proxyholders 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. If the adjournment is for more than 30 days, notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for determination of stockholders entitled
to vote is fixed for the adjourned meeting, the Board of Directors shall fix as the record date for determining stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for the determination of stockholders
entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record as of the record date so fixed for notice of such adjourned meeting. At any adjourned meeting any business may be transacted that
could have been transacted at the original meeting.

not be more than 60 nor less than 10 days before the date of such meeting. If the Board of Directors so fixes a date, such date shall also be the record date for determining the stockholders 

  
 12 








 
entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for
making such determination. If no record date is fixed by the Board of Directors, 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 such meeting is held. 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 that the Board of Directors may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record
date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting. 

(b) In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede
the date upon which the resolution fixing the record date is adopted, and which record date shall not be more than 60 days prior to such action. If no such record date is fixed, the record date for determining stockholders for any such purpose shall
be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

restricted by the Certificate of Incorporation, in order that the Corporation may determine the stockholders entitled to express consent to corporate action in writing without a meeting, 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 shall not be more than 10 days after the date upon which the resolution fixing the record date is adopted by
the Board of Directors. If no record date for determining stockholders entitled to express consent to corporate action in writing without a meeting is fixed by the Board of Directors, (i) when no prior action of the Board of Directors is
required by law, the record date for such purpose 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 law, and (ii) if prior action
by the Board of Directors is required by law, the record date for such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

certificate may be issued upon such terms as may be determined or authorized by the Board of Directors or by the Chief Executive Officer or the President if the Board of Directors does not do so. When authorizing such issuance of a new certificate,
the Board of Directors or any such officer may, as a condition precedent to the issuance thereof, require the owner of such lost, stolen, mutilated or destroyed certificate or certificates, or such owner’s legal representative, to advertise the
same in such manner as the Board of Directors or such officer shall require and/or to give the Corporation a bond or indemnity, in such sum or on such terms and conditions as the Board of Directors or such officer may direct, as indemnity against
any claim that may be made against the Corporation on account of the certificate alleged to have been lost, stolen, mutilated or destroyed or on account of the issuance of such new certificate or uncertificated shares.

INDEMNIFICATION OF DIRECTORS AND OFFICERS 

Section 1. Right to Indemnification. The Corporation shall indemnify and hold harmless, to the fullest extent permitted by law as
it presently exists or may hereafter be amended, 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 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 or agent of another corporation or of a partnership, limited liability company, joint venture, trust, enterprise or nonprofit or other 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
Section 3 of 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 by the Board of Directors. 
 Section 2. Right to Advancement of Expenses. The Corporation
shall, to the fullest extent permitted by law, pay the expenses (including attorneys’ fees) incurred by a Covered Person 

  
 15 








 
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. The
rights to indemnification and to the advancement of expenses conferred in Sections 1 and 2 of this Article XI shall be contract rights which shall continue as to a Covered Person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of such Covered Person’s heirs, executors and administrators. 
 Section 3. Claims. If a claim for
indemnification under this Article XI (following the final disposition of any applicable proceeding) is not paid in full within 60 days after the Corporation has received a claim therefor by the Covered Person, or if a claim for any advancement of
expenses under this Article XI is not paid in full within 30 days after the Corporation has received a statement or statements requesting such amounts to be advanced, the Covered Person shall thereupon (but not before) be entitled to file suit to
recover the unpaid amount of such claim. If successful in whole or in part, the Covered Person shall be entitled to be paid the expense of prosecuting such claim 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 or advancement of expenses under law. 

Section 4. Non-exclusivity 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 statute, provision of the Certificate of Incorporation, agreement, vote of stockholders or of disinterested directors, these Bylaws or otherwise. 

Section 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 or agent of another corporation, partnership, limited liability company, joint venture, trust, enterprise or nonprofit or other 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 nonprofit or other entity. 

Section 6. Amendment or Repeal. Any repeal or modification of the foregoing provisions of this Article XI 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. Insurance. The Corporation shall have power to purchase and maintain insurance on behalf of any person who is or was 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 or of a partnership, limited liability company, joint venture, trust,
enterprise or nonprofit or other entity, against any liability asserted against such person or incurred by such person in any such capacity, or arising out of such person’s status as such, and related expenses, whether or not the Corporation
would have the power to indemnify such person against such liability under the provisions of law. 
 Section 8. 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.
