2.1            Corporate
Governance.


 


(a)            Board
of Directors. The Company hereby agrees that:


 


(i)            The
Arsenal Stockholders shall have the right, but not the obligation, to nominate to the Board: two (2) directors until the latest
of: (A) from the Effective Date until the two (2) year anniversary of the Effective Date for so long as the Arsenal Stockholders
continue to own 100% of the Shares Arsenal purchased in connection with the Sale Transaction, as identified on Exhibit B of the
Purchase Agreement, (B) after the two (2) year anniversary of the Effective Date, for so long as the Arsenal Amount represents
at least 12% of the total number of Adjusted Shares Outstanding and (C) from the Effective Date until the five (5) year anniversary
of the Effective Date, for so long as the Arsenal Stockholders continue to own 100% of the Shares Arsenal purchased in connection with
the Sale Transaction, as identified on Exhibit B of the Purchase Agreement, as such number may be adjusted from time to time for
any reorganization, recapitalization, stock dividend, stock split, reverse stock split or other similar changes in the Company’s
capitalization. The Arsenal Stockholders shall have the right, but not the obligation, to nominate to the Board one (1) director,
for so long as the Arsenal Amount represents at least 6%, but less than 12%, of the total number of Adjusted Shares Outstanding. The
designees of the Arsenal Stockholders pursuant to this Section 2.1(a)(i) shall be referred to herein as the “Arsenal
Director Nominees.” Notwithstanding the foregoing, (i) any such individual designated by the Arsenal Stockholders shall
be (A) a full-time senior employee of Arsenal Capital Management LP or its Affiliates, such as an investment partner, a senior partner
or an operating partner, or (B) another individual that the Arsenal Stockholders reasonably believe is appropriately qualified to
serve as a director on the board of a public company, provided that the designation of any such other individual pursuant to this clause
(B) shall be subject to the consent of the Board (excluding any Arsenal Director Nominees), acting in its sole discretion; (ii) if,
at any time, there are two (2) Arsenal Director Nominees appointed to the Board and the Arsenal Stockholders cease to have the right
to designate two (2) Arsenal Director Nominees but continue to have the right to designate one (1) Arsenal Director Nominee
under this Section 2.1(a)(i), the Arsenal Director Nominee who is closest in time to being subject to re-election shall irrevocably
offer to tender his or her resignation to the Board within five (5) business days after (A) the Arsenal Stockholders determine
that, or (B) the Company provides notice to the Arsenal Stockholders that, the Arsenal Amount represents less than the applicable
threshold set forth in this Section 2.1(a)(i), which resignation may be accepted or rejected by the Board (excluding any
Arsenal Director Nominees) in its sole discretion (it being understood that, if the Board (excluding any Arsenal Director Nominees) accepts
such offer, then such Arsenal Director Nominee shall promptly and irrevocably tender his or her resignation to the Board); and (iii) the
right of the Arsenal Stockholders to designate any Arsenal Director Nominees pursuant to this Section 2.1(a)(i) shall
automatically terminate at such time that the Arsenal Amount represents less than 6% of the total number of Adjusted Shares Outstanding,
and any Arsenal Director Nominee(s) serving on the Board at such time shall, and the Arsenal Stockholders shall cause any such Arsenal
Director Nominee(s) to, irrevocably offer to tender his or her resignation to the Board within five (5) business days after
(A) the Arsenal Stockholders determine that, or (B) the Company provides notice to the Arsenal Stockholders that, the Arsenal
Amount represents less than the applicable threshold set forth in this Section 2.1(a)(i), which resignation may be accepted
or rejected by the Board (excluding any Arsenal Director Nominees) in its sole discretion (it being understood that if the Board (excluding
any Arsenal Director Nominees) accepts such offer, then such Arsenal Director Nominee shall promptly and irrevocably tender his or her
resignation to the Board). As long as the Board of Directors is classified, the Arsenal Director Nominees shall be Class I and Class III
directors, as designated by the Arsenal Stockholders. In the event that the Arsenal Stockholders have nominated less than the total number
of designees that they are entitled to nominate pursuant to this Section 2.1(a)(i), the Arsenal Stockholders shall have the
right to nominate such additional designees to which they are entitled, in which case, the Company and the Board shall take all necessary
corporation action (including increasing the size of the Board to create a vacancy), to the fullest extent permitted by applicable law
(including with respect to fiduciary duties under Delaware law), to (x) enable the Arsenal Stockholders to nominate such additional
individuals at the next annual meeting of the Company in which the class of director the Arsenal Stockholders did not nominate as a designee
is subject to election, in each case, in accordance with this Section 2.1(a)(i). The Arsenal Stockholders hereby agree that
any Arsenal Director Nominees nominated pursuant to this Section 2.1(a)(i) or that serve on the Board must comply with
and will be subject to any rules, procedures, requirements and other obligations which apply to the other directors of the Board from
time-to-time.


 






    5


     


    

 


(ii)            The
Company shall include as part of the slate that is included in the proxy statement (or consent solicitation or similar document) of the
Company relating to the election of directors to the Board of Directors (a “Director Election Proxy Statement”) the
Arsenal Director Nominees (if such proxy statement (or consent solicitation or similar document) relates to the election of directors
of the class or classes to which Arsenal Director Nominees belong) pursuant to Section 2.1(a)(i) and shall provide at
least the same level of support for the election of each person nominated pursuant to Section 2.1(a)(i) as it provides
to any other individual standing for election as a director of the Company as part of such Company slate of directors. Unless an Arsenal
Stockholder notifies the Company otherwise prior to the mailing to stockholders of the Director Election Proxy Statement (or, if earlier,
the filing of the definitive Director Election Proxy Statement with the SEC), the Arsenal Director Nominees for such election shall be
presumed to be the same Arsenal Director Nominees currently serving on the Board, and no further action shall be required of the Arsenal
Stockholders for the Board to include such Arsenal Director Nominees on the Board’s slate; provided, that, in the event
the Arsenal Stockholders are no longer entitled to nominate the full number of Arsenal Director Nominees then serving on the Board, the
Arsenal Stockholders shall provide advance written notice to the Company of which currently serving Arsenal Director Nominee(s) shall
be excluded from the Board slate, and of any other changes to the list of Arsenal Director Nominees. If the Arsenal Stockholders fail
to provide such notice prior to the mailing to stockholders of the Director Election Proxy Statement relating to such election (or, if
earlier, the filing of the definitive Director Election Proxy Statement with the SEC), a majority of the independent directors then serving
on the Board shall determine which of the Arsenal Director Nominees of the Arsenal Stockholders then serving on the Board will be included
in the Board’s slate. The Company agrees to provide written notice of the preparation of a Director Election Proxy Statement to
the Arsenal Stockholders at least 20 business days, but no more than 40 business days, prior to the earlier of the mailing and the filing
date of any Director Election Proxy Statement.


 






    6


     


    

 


(iii)            In
the event that an Arsenal Director Nominee shall cease to serve as a director for any reason (other than (i) the failure of the
stockholders of the Company to elect such individual as a director or (ii) for the avoidance of doubt, where an Arsenal Director
Nominee ceases to serve due to the Arsenal Stockholders no longer having a right to designate such an Arsenal Director Nominee pursuant
to Section 2.1(a)(i)), the Arsenal Stockholders shall have the right to designate a replacement Arsenal Director Nominee
and the Company agrees to take all reasonable actions necessary to cause the appointment of any such replacement Arsenal Director Nominee
to fill the vacancy resulting therefrom; it being understood that any such designee shall serve the remainder of the term of the director
whom such designee replaces. For the avoidance of doubt, it is understood that the failure of the stockholders of the Company to elect
any Arsenal Director Nominee shall not affect the right of the Arsenal Stockholders to designate such Arsenal Director Nominee pursuant
to Section 2.1(a)(i) in connection with any future election of directors of the Company. If an Arsenal Director Nominee
is not appointed or elected to the Board because of such person’s death, disability, disqualification, withdrawal as a nominee
or for other reason is unavailable or unable to serve on the Board, the Arsenal Stockholders shall be entitled to designate promptly
another nominee and the director position for which the original Arsenal Director Nominee was nominated shall not be filled pending such
designation. In the event the Arsenal Stockholders may designate a replacement nominee under this Section 2.1(a)(iii), the
Arsenal Stockholders must provide notice of any such replacement as soon as reasonably practicable.


 


(b)            Each
Arsenal Stockholder (and any Co-Investor, or any of its Affiliates to which such Co-Investor has transferred Shares in accordance with
this Agreement, as applicable) hereby agrees with the Company that for so long as any Arsenal Stockholder is entitled to designate an
Arsenal Stockholder Nominee pursuant to Section 2.1(a)(i), such Arsenal Stockholder (and any Co-Investor, as applicable)
shall vote all of its Shares in favor of each individual standing for election as a director of the Company as part of the Company’s
slate of directors that is included in any Director Election Proxy Statement (or consent solicitation or similar document) of the Company
relating to the election of directors to the Board of Directors and whose election the Board of Directors has recommended.


 


(c)            The
Company will pay directly or reimburse, or cause to be paid directly or reimbursed, the actual and reasonable out-of-pocket costs and
expenses incurred by the Arsenal Director Nominees hereunder in connection with such Arsenal Director Nominees’ board service (including
travel but not private air travel), in the same manner and to the same extent as other directors of the Company.


 


(d)            At
the Effective Date, the Board shall be comprised of eleven members. The initial Arsenal Director Nominees shall be Steve McLean as a
Class III director and Dave Spaight as a Class I director.


 


(e)            From
and after the Effective Date hereof, (i) for so long as the Arsenal Stockholders have the right to designate two (2) Arsenal
Director Nominees for nomination to serve on the Board of Directors pursuant to Section 2.1(a)(i), the Board (excluding the
Arsenal Directors Nominees) shall appoint one (1) Arsenal Director Nominee to the Nominating and Corporate Governance Committee
and one (1) Arsenal Director Nominee to the Compensation Committee, it being understood that the Board (excluding the Arsenal Director
Nominees) may determine in its sole discretion which Arsenal Director Nominee is appointed to which committee; (ii) at such time
that the Arsenal Stockholders cease to have the right to designate two (2) Arsenal Director Nominees but continue to have the right
to designate one (1) Arsenal Director Nominee for nomination to serve on the Board of Directors, in each case, pursuant to Section 2.1(a)(i),
the Board (excluding any Arsenal Director Nominees) shall (x) appoint one (1) Arsenal Director Nominee (who is specified by
the Arsenal Stockholders) to either the Nominating and Corporate Governance Committee or the Compensation Committee (or allow such Arsenal
Director Nominee to continue to serve on such committee, as applicable), it being understood that the Board (excluding the Arsenal Director
Nominees) shall determine, after good faith consultation with the Arsenal Stockholders, which of the committees such Arsenal Director
Nominee be appointed to and serve, and (y) immediately remove the other Arsenal Director Nominee from any and all committees of
the Board; and (iii) at such time that the Arsenal Stockholders cease to have the right to designate any Arsenal Director Nominees
for nomination to serve on the Board of Directors pursuant to Section 2.1(a)(i), the Board (excluding any Arsenal Director
Nominees) shall immediately remove any and all Arsenal Director Nominees from any and all committees of the Board; provided that,
in the case of the foregoing (i) and (ii), any such Arsenal Director Nominee shall be eligible to serve on the applicable committee
under applicable law or listing standards of the NASDAQ Global Select Market, including any applicable independence requirements (subject
in each case to any applicable exceptions).


 






    7


     


    

 


(f)            Notwithstanding
anything in this Agreement to the contrary, if the Board of Directors (excluding any Arsenal Director Nominees) reasonably determines
that an Arsenal Director Nominee serving on the Board of Directors is a director of another company that (i) engages in the same
or similar business activities or lines of business as the Company or any of its Subsidiaries or (ii) is reasonably and in good
faith deemed to be competing with the Company or any of its Subsidiaries in any material respect (such Arsenal Director Nominee is a
 “Competing Arsenal Director Nominee”), the Board of Directors (excluding any Arsenal Director Nominee) may determine,
after good faith consultation with the Arsenal Stockholders, and upon good faith review of all of the relevant facts and circumstances,
including all documentation provided by the Arsenal Stockholders in connection with such determination, to immediately remove such Arsenal
Director Nominee, in which case the Arsenal Stockholders shall be entitled to designate promptly another nominee pursuant to and in accordance
with Section 2.1(a)(i) (who would not be a Competing Arsenal Director Nominee) and the director position for which the
original Arsenal Director Nominee was nominated shall not be filled pending such designation.


 


2.2            Confidentiality.
Each Arsenal Stockholder (and any Co-Investor, or any of its Affiliates to which such Co-Investor has transferred Shares in accordance
with this Agreement, as applicable) shall, and shall cause its Affiliates and its and its Affiliates’ representatives to, maintain
the confidentiality of any confidential and proprietary information of the Company and its Subsidiaries (“Proprietary Information”)
using the same standard of care, but in no event less than reasonable care, as it applies to its own confidential information, except
(i) for any Proprietary Information which is publicly available (other than as a result of dissemination by such Arsenal Stockholder
or such Co-Investor, as applicable, its Affiliates or its or its Affiliates’ representatives in breach of this Agreement) or a
matter of public knowledge generally, (ii) if the release of such Proprietary Information is ordered pursuant to a subpoena or other
order from a court of competent jurisdiction or other applicable law, rule, regulation, legal or judicial process or audit or inquiries
by a regulator, bank examiner or self-regulatory organization (collectively, “Law”), following delivery of prior written
notice to the Company (to the extent reasonably practicable and permitted under applicable Law), (iii) for Proprietary Information
that was known to such Arsenal Stockholder or such Co-Investor (or its Affiliates) on a non-confidential basis, without, to such Person’s
knowledge, breach of any confidentiality obligations to the Company or its Affiliates in respect thereof, prior to its disclosure by
the Company or its Affiliates or (iv) if such Proprietary Information is or has been independently developed or conceived by any
Arsenal Stockholder or any Co-Investor (or its Affiliates) without use of or reference to the Company’s Proprietary Information.
The Company recognizes that each Arsenal Director Nominee (A) will from time to time receive non-public information concerning the
Company, and (B) may share such information on a case-by-case basis, with (i) the members of the healthcare investment committee
of the Arsenal Stockholders (or their controlling Affiliates) to enable such members to fulfill their fiduciary obligations to the investors
in the Arsenal Stockholders (or their controlling Affiliates) and (ii) the other employees of the Arsenal Stockholders (or their
controlling Affiliates), subject, in the case of this clause (ii) only, to the prior consent of the Company, which consent may be
withheld in its sole discretion.

the parties may have under this Agreement or otherwise.


 


3.2            Entire
Agreement; Amendment; Waiver. This Agreement, together with the Letter Agreement (with respect to the Company and Arsenal), and the
Purchase Agreement (and any document executed by a Co-Investor pursuant to the Purchase Agreement), sets forth the entire understanding
of the parties, and as of the date hereof supersedes all prior agreements and all other arrangements and communications, whether oral
or written, with respect to the subject matter hereof and thereof. This Agreement may be amended, modified, supplemented, restated, waived
or terminated only upon (i) the written consent of the Company and (ii) the Arsenal Consent. Except as otherwise expressly
provided for hereby, no waiver of or consent to any departure from any provision of this Agreement shall be effective unless signed in
writing by the Company if it is entitled to the benefit thereof or the Arsenal Consent if the Arsenal Stockholders are entitled to the
benefit thereof.


 


3.3            Severability.
It is the desire and intent of the parties that the provisions of this Agreement be enforced to the fullest extent permissible under
the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, the invalidity or unenforceability
of any particular provision of this Agreement shall not affect the other provisions hereof, and this Agreement shall be construed in
all respects as if the invalid or unenforceable provision were omitted. Notwithstanding the foregoing, if such provision could be more
narrowly drawn so as not to be invalid or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so more narrowly
drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision
in any other jurisdiction.

Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and to their respective transferees,
successors and assigns; provided, however, that no right or obligation under this Agreement may be assigned except as expressly
provided herein, it being understood that (i) the Company’s right hereunder may be assigned by the Company to any corporation
or other entity which is the surviving entity in a merger, consolidation or like event involving the Company, and (ii) an Arsenal

Without affecting any other provision of this Agreement requiring termination of any rights in favor of any Arsenal Stockholder, the

tender their resignation to the Board shall survive until all such Arsenal Director Nominees are no longer on the Board.

3.10            Other
Business Opportunities.


 


(a)            The
parties expressly acknowledge and agree that to the fullest extent permitted by applicable law: (i) each of the Arsenal Stockholders
(in each case, including (A) their respective Affiliates, (B) any portfolio company in which they or any of their respective
affiliated investment funds or Affiliates have made a debt or equity investment (and vice versa) and (C) their respective limited
partners, non-managing members or other similar direct or indirect investors) and each Arsenal Director Nominee has the right to, and
shall have no duty (fiduciary, contractual or otherwise) not to, directly or indirectly engage in and possess interests in other business
ventures of every type and description, including those engaged in the same or similar business activities or lines of business as the
Company or any of its Subsidiaries or deemed to be competing with the Company or any of its Subsidiaries, on its own account, or in partnership
with, or as an employee, officer, director or shareholder of any other Person, with no obligation to offer to the Company or any of its
Subsidiaries the right to participate therein; (ii) each of the Arsenal Stockholders (in each case, including (A) their respective
Affiliates, (B) any portfolio company in which they or any of their respective affiliated investment funds or Affiliates have made
a debt or equity investment (and vice versa) and (C) their respective limited partners, non-managing members or other similar direct
or indirect investors) and each Arsenal Director Nominee may invest in, or provide services to, any Person that directly or indirectly
competes with the Company or any of its Subsidiaries; and (iii) in the event that any of the Arsenal Stockholders (in each case,
including (A) their respective Affiliates, (B) any portfolio company in which they or any of their respective affiliated investment
funds or Affiliates have made a debt or equity investment (and vice versa) and (C) their respective limited partners, non-managing
members or other similar direct or indirect investors) or any Arsenal Director Nominee acquires knowledge of a potential transaction
or matter that may be a corporate or other business opportunity for the Company or any of its Subsidiaries, such Person shall have no
duty (fiduciary, contractual or otherwise) to communicate or present such corporate opportunity to the Company or any of its Subsidiaries,
as the case may be, and, notwithstanding any provision of this Agreement to the contrary, shall not be liable to the Company or any of
its Subsidiaries for breach of any duty (fiduciary, contractual or otherwise) by reason of the fact that such Person, directly or indirectly,
pursues or acquires such opportunity for itself, directs such opportunity to another Person or does not present such opportunity to the
Company or any of its Subsidiaries. For the avoidance of doubt, the parties acknowledge that this paragraph is intended to disclaim and
renounce, to the fullest extent permitted by applicable law, any right of the Company or any of its Subsidiaries with respect to the
matters set forth herein, and this paragraph shall be construed to effect such disclaimer and renunciation to the fullest extent permitted
by law.


 


(b)            The
Company and each of its Subsidiaries hereby, to the fullest extent permitted by applicable law:


 


(i)            confirms
that no Arsenal Stockholder nor any of its Affiliates has any duty to the Company or any of its Subsidiaries other than the specific
covenants and agreements set forth in this Agreement;


 


(ii)            acknowledges
and agrees that (A) in the event of any conflict of interest between the Company or any of its Subsidiaries, on the one hand, and
any Arsenal Stockholder or any of its Affiliates, on the other hand, such Arsenal Stockholder or any of its Affiliates (and any Arsenal
Director Nominee) may act in its best interest and (B) none of the Arsenal Stockholders nor any of their respective Affiliates (or
any Arsenal Director Nominee), shall be obligated (1) to reveal to the Company or any of its Subsidiaries confidential information
belonging to or relating to the business of such Person or any of its Affiliates or (2) to recommend or take any action in its capacity
as a Stockholder or director, as the case may be, that prefers the interest of the Company or its Subsidiaries over the interest of such
Person; and


 


(iii)            waives
any claim or cause of action against any of the Arsenal Stockholders, any Arsenal Director Nominee and any officer, employee, agent or
Affiliate of any such Person that may from time to time arise in respect of a breach by any such person of any duty or obligation disclaimed
under Section 3.10(b)(i) or Section 3.10(b)(ii).


 


(c)            Each
of the parties hereto agrees that the waivers, limitations, acknowledgments and agreements set forth in this Section 3.10
shall not apply to any alleged claim or cause of action against any Arsenal Stockholder based upon the breach or nonperformance by such
Arsenal Stockholder of this Agreement or any other agreement to which such Person is a party.


 






    12


     


    

 


(d)            The
provisions of this Section 3.10, to the extent that they restrict the duties and liabilities of any of the Arsenal Stockholders
or any Arsenal Director Nominee otherwise existing at law or in equity, are agreed by the parties hereto to replace such other duties
and liabilities of the Arsenal Stockholders or any such Arsenal Director Nominee to the fullest extent permitted by applicable law.


 


3.11            No
Waiver. No course of dealing and no delay on the part of any party hereto in exercising any right, power or remedy conferred by this
Agreement shall operate as waiver thereof or otherwise prejudice such party’s rights, powers and remedies. No single or partial
exercise of any rights, powers or remedies conferred by this Agreement shall preclude any other or further exercise thereof or the exercise
of any other right, power or remedy. The Arsenal Stockholders shall not be obligated to designate all (or any) of the Arsenal Director
Nominees they are entitled to designate pursuant to this Agreement for any election of directors but the failure to do so shall not constitute
a waiver of their rights hereunder with respect to future elections; provided, however, that in the event the Arsenal Stockholders
fail to designate all (or any) of the Arsenal Director Nominees they are entitled to designate pursuant to this Agreement prior to the
mailing to stockholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive
Director Election Proxy Statement with the SEC), the Nominating and Corporate Governance Committee of the Board shall be entitled to
nominate individuals in lieu of such Arsenal Director Nominees for inclusion in the Board’s slate and the applicable Director Election
Proxy Statement with respect to the election for which such failure occurred and the Arsenal Stockholders shall be deemed to have waived
its rights hereunder with respect to such election.


 


3.12            Costs
and Expenses. Each party shall pay its own costs and expenses incurred in connection with this Agreement, and any and all other documents
furnished pursuant hereto or in connection herewith.


 


3.13            Counterpart.
This Agreement may be executed in two or more counterparts each of which shall be deemed an original but all of which together shall
constitute one and the same instrument, and all signatures need not appear on any one counterpart.


 


3.14            Headings.
All headings and captions in this Agreement are for purposes of reference only and shall not be construed to limit or affect the substance
of this Agreement.


 


3.15            Consent
to Jurisdiction. The Company and each of the Arsenal Stockholders, by its, his or her execution hereof, (i) hereby irrevocably
submit to the exclusive jurisdiction of the state and federal courts in the State of Delaware for the purposes of any claim or action
arising out of or based upon this Agreement or relating to the subject matter hereof, (ii) hereby waive, to the extent not prohibited
by applicable law, and agree not to assert by way of motion, as a defense or otherwise, in any such claim or action, any claim that it
or he is not subject personally to the jurisdiction of the above-named courts, that its, his or her property is exempt or immune from
attachment or execution, that any such proceeding brought in the above-named court is improper or that this Agreement or the subject
matter hereof may not be enforced in or by such court and (iii) hereby agree not to commence any claim or action arising out of
or based upon this Agreement or relating to the subject matter hereof other than before the above-named courts nor to make any motion
or take any other action seeking or intending to cause the transfer or removal of any such claim or action to any court other than the
above-named courts whether on the grounds of inconvenient forum or otherwise. The Company and each of the Arsenal Stockholders hereby
consent, to the fullest extent permitted by law, to service of process in any such proceeding, and agree that service of process by registered
or certified mail, return receipt requested, at its address specified pursuant to Section 3.4 is reasonably calculated to
give actual notice.

OF JURY TRIAL. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH PARTY HERETO HEREBY WAIVES AND COVENANTS
THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE
OR ACTION, CLAIM, CAUSE OF ACTION OR SUIT (IN CONTRACT, TORT OR OTHERWISE), INQUIRY, PROCEEDING OR INVESTIGATION ARISING OUT OF
OR BASED UPON THIS AGREEMENT OR THE SUBJECT MATTER HEREOF OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE TRANSACTIONS CONTEMPLATED
HEREBY, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING. EACH PARTY HERETO ACKNOWLEDGES THAT IT HAS BEEN INFORMED BY THE
OTHER PARTIES HERETO THAT THIS SECTION 3.16 CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH THEY ARE RELYING AND WILL RELY IN

WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.


 


3.17            Representations
and Warranties. The Company hereby represents and warrants to the Arsenal Stockholders that it has full power, capacity, legal right
and authority to execute, deliver and perform this Agreement, and each Arsenal Stockholder hereby represents and warrants to the Company
as follows:


 


(a)            Such
Arsenal Stockholder, to the extent applicable, is duly organized or incorporated, validly existing and in good standing under the laws
of the jurisdiction of its organization or incorporation and has all requisite power and authority to conduct its business as it is now
being conducted and is proposed to be conducted. Such Arsenal Stockholder has the full power, authority and legal right to execute, deliver
and perform this Agreement. The execution, delivery and performance of this Agreement have been duly authorized by all necessary action,
corporate or otherwise, of such Arsenal Stockholder. This Agreement has been duly executed and delivered by such Arsenal Stockholder
and constitutes its, his or her legal, valid and binding obligation, enforceable against it, him or her in accordance with its terms,
subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally.


 


(b)            The
execution and delivery by such Arsenal Stockholder of this Agreement, the performance by such Arsenal Stockholder of its, his or her
obligations hereunder by such Arsenal Stockholder does not and will not violate (i) in the case of parties who are not individuals,
any provision of its organizational or constituent documents, (ii) any provision of any material agreement to which it, he or she
is a party or by which it, he or she is bound or (iii) any law, rule, regulation, judgment, order or decree to which it, he or she
is subject. No notice, consent, waiver, approval, authorization, exemption, registration, license or declaration is required to be made
or obtained by such Arsenal Stockholder in connection with the execution, delivery or enforceability of this Agreement.


 


(c)            Such
Arsenal Stockholder is not currently in violation of any law, rule, regulation, judgment, order or decree, which violation could reasonably
be expected at any time to have a material adverse effect upon such Arsenal Stockholder’s ability to enter into this Agreement
or to perform its, his or her obligations hereunder. There is no pending legal action, suit or proceeding that would materially and adversely
affect the ability of such Arsenal Stockholder to enter into this Agreement or to perform its, his or her obligations hereunder.


 






    14


     


    

 


3.18            Consents,
Approvals and Actions. If any consent, approval or action of the Arsenal Stockholders is required at any time pursuant to this Agreement,
such consent, approval or action shall be deemed given if the holders of a majority of the shares of Common Stock held by the Arsenal
Stockholders at such time provide such consent, approval or action in writing at such time.


 


3.19            No
Third Party Liabilities. This Agreement may only be enforced against the named parties hereto (or any of their permitted assigns
pursuant to Section 3.5 hereto). All claims or causes of action (whether in contract or tort) that may be based upon, arise
out of or relate to any of this Agreement, or the negotiation, execution or performance of this Agreement (including any representation
or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement), may be made only against
the entities that are expressly identified as parties hereto, as applicable (or any of their permitted assigns pursuant to Section 3.5
hereto); and no past, present or future director, officer, employee, incorporator, member, partner, stockholder, Affiliate, portfolio
company in which any such party or any of its investment fund Affiliates have made a debt or equity investment (and vice versa), agent,
attorney or representative of any party hereto (including any Person negotiating or executing this Agreement on behalf of a party hereto),
unless a party to this Agreement (or a permitted assign pursuant to Section 3.5 hereto), shall have any liability or obligation
with respect to this Agreement or with respect any claim or cause of action (whether in contract or tort) that may arise out of or relate
to this Agreement, or the negotiation, execution or performance of this Agreement (including a representation or warranty made in or
in connection with this Agreement or as an inducement to enter into this Agreement).


 


3.20            Mutual
Drafting. The Company and each Arsenal Stockholder confirms that each Arsenal Stockholder has had the opportunity to independently
participate with the Company and its subsidiaries in the negotiation of the transaction contemplated hereby with the advice of its own
counsel and advisors. The parties are sophisticated and have been represented by attorneys throughout the transactions contemplated by
this Agreement who have carefully negotiated the provisions hereof. As a consequence, the parties do not intend that the presumptions
of laws or rules relating to the interpretation of contracts against the drafter of any particular clause should be applied to this
Agreement or any agreement or instrument executed in connection herewith and therefore waive their effects.


 


3.21            Enforcement.
Each of the parties hereto covenant and agree that the disinterested members of the Board have the right to enforce, waive or take any
other action with respect to this Agreement on behalf of the Company.

This Agreement shall only become effective, and the Prior Agreement shall only be terminated, upon the Effective Date. The parties agree
that all rights and obligations under the Prior Agreement, including the right to appoint Arsenal Director Nominees (as that term is
defined in the Prior Agreement) under Section 2.1 of the Prior Agreement, will terminate upon the Effective Date. Notwithstanding
anything else in this Agreement, including Section 3.7, this Agreement shall terminate automatically and have no force or
