the Company to the Rights Agent as fees, but not including reimbursable expenses, during the twelve (12) months immediately preceding
the event for which recovery from the Rights Agent is being sought. No provision of this Agreement shall require the Rights Agent to expend
or risk its own funds, take any action that it believes would expose or subject it to expense or liability, or otherwise incur any financial
liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers.

(b)

result in the incurrence of expenses by the Rights Agent, unless the Representative (on behalf of the Holders) shall furnish the Rights
Agent with reasonable security and indemnity for any costs and expenses that may be incurred.


 


Section 3.02           
Certain Rights of Rights Agent.


 


(a)

implied covenants or obligations shall be read into this Agreement against the Rights Agent.


 


(b)               
The Rights Agent may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order or other paper or document believed by it in the absence of faith
to be genuine and to have been signed or presented by the proper party or parties.


 


(c)               
Whenever the Rights Agent shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting
any action hereunder, the Rights Agent may, in the absence of bad faith, gross negligence or willful misconduct (in each case, as determined
by a final non-appealable order of a court of competent jurisdiction) on its part, rely upon the written direction of the Representative.


 


(d)               
The Rights Agent may engage and consult with counsel of its selection and the advice or opinion of such counsel shall be full and
complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in the absence of faith and
in reliance thereon.


 


(e)               
Any permissive rights of the Rights Agent hereunder shall not be construed as a duty.


 


(f)

successors, assigns, directors, officers, managers, employees, agents, attorneys, accountants and experts (collectively, the “Indemnitees”),
against any and all loss, liability, obligation, damage, fine, settlement, penalty, action, judgment, suit, cost, disbursement, proceeding,
investigation, claim, demand or expense of any kind or nature whatsoever (including, without limitation, the reasonable fees and expenses
of legal counsel and the costs and expenses of defending the Indemnitee against any claim of liability arising therefrom) (collectively,
“Losses”) that may be imposed on, incurred by, or asserted against any Indemnitee, at any time, and in any way relating
to, arising out of or in connection with the execution, delivery or performance of this Agreement, the enforcement of any rights or remedies
in connection with this Agreement, and the payment, transfer or other application of funds pursuant to this Agreement, or as may arise
by reason of any act, omission or error of the Indemnitee; provided, however, that no Indemnitee shall be entitled to be so indemnified,
defended, protected, saved or kept harmless to the extent such Loss was caused by its own willful misconduct, bad faith or gross negligence
(each as determined by a final, non-appealable judgment of a court of competent jurisdiction). The Company’s obligations under this
Section 3.02(f) to indemnify the Rights Agent shall survive the resignation or removal of any Rights Agent and the termination
of this Agreement. With the Company’s consent which shall not be unreasonably withheld, conditioned or delayed, the Rights Agent’s
Loss may be satisfied from the Consideration and deducted from the amounts payable to the Holders hereunder.

its agents, representatives, attorneys, custodians and/or nominees and the Rights Agent shall not be answerable or accountable for any
act, default, neglect or misconduct of any such agents, representatives, attorneys, custodians and/or nominees, absent gross negligence,

in the selection and continued employment thereof.

the Rights Agent shall not be required to give any note or surety in respect of the execution of such powers or otherwise in respect
of the premises.


 


(j)                
In the event the Rights Agent reasonably believes any ambiguity or uncertainty exists hereunder or in any notice, instruction,
direction, request or other communication, paper or document received by the Rights Agent hereunder, the Rights Agent may, in its sole
discretion, refrain from taking any action, and shall be fully protected and shall not be liable in any way to the Company or other Person
or entity for refraining from taking such action, unless the Rights Agent receives written instructions signed by the Company which eliminate
such ambiguity or uncertainty to the reasonable satisfaction of the Rights Agent.

and the Representative shall incur no liability for or in respect of any action taken, suffered or omitted to be taken by it under the
provisions of this Agreement in reliance upon such certificate. The Representative shall be fully authorized and protected in relying
upon the most recent instructions received from the Company. In the event the Representative believes any ambiguity or uncertainty exists
hereunder or in any notice, instruction, direction, request or other communication, paper or document received by the Representative hereunder,
the Representative, may, in its sole discretion, refrain from taking any action, and shall be fully protected and shall not be liable
in any way to the Company or any other person for refraining from taking such action, unless the Representative receives written instructions
from the Company that eliminates such ambiguity or uncertainty to the satisfaction of the Representative.


 


(e)               
The Representative may engage and consult with counsel of its selection and the written advice of such counsel or any opinion of
counsel shall be full and complete authorization and protection to the Representative in respect of any action taken, suffered or omitted
to be taken by it hereunder in reliance thereon in the absence of willful misconduct, bad faith or gross negligence on the part of the
Representative (as determined by a final, non-appealable judgment of a court of competent jurisdiction).


 


(f)                
The permissive rights of the Representative to do things enumerated in this Agreement shall not be construed as a duty.


 


(g)               
The Representative shall not have any liability for or be under any responsibility in respect of the validity of this Agreement
or the execution and delivery hereof; nor shall it be responsible for any breach by the Company of any covenant or failure by the Company
to satisfy conditions contained in this Agreement.


 


(h)               
The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all such further and other acts, instruments and assurances as may reasonably be required or requested by the Representative
for the carrying out or performing by the Representative of its duties under this Agreement.


 


(i)                
The Representative may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either
itself or by or through its attorneys or agents, and the Representative shall not be answerable or accountable for any act, omission,
default, neglect or misconduct of any such attorneys or agents or for any loss to the Company, to the Holders, the Rights Agent or any
other person resulting from any such act, omission, default, neglect or misconduct, absent gross negligence or bad faith in the selection
and continued employment thereof (which gross negligence or bad faith must be determined by a final, non-appealable judgment of a court
of competent jurisdiction) and, in the event of arbitration or litigation in connection with the matters contemplated herein, the Representative
may, but shall not be obligated to, engage and consult with tax experts, valuation firms and other experts and third parties that it,
in its sole and absolute discretion, deems appropriate or necessary to enable it to discharge its duties hereunder.

Section 5.04           
Successor Representative.


 


(a)               
The Representative and any successor Representative may resign and be discharged from its duties under this Agreement at any time
by giving written notice thereof to the Company, specifying a date when such resignation shall take effect, which notice shall be sent
at least thirty (30) days before the date so specified.


 


(b)               
The Acting Holders may remove the Representative or any successor Representative at any time by giving written notice thereof to
the Representative specifying a date when such removal shall take effect, which notice shall be sent at least thirty (30) days before
the date so specified. In the event that the Representative dies, becomes unable to perform his or her responsibilities hereunder or resigns
or is removed from such position, the Acting Holders shall be authorized to and shall select another representative to fill such vacancy
and such substituted representative shall be deemed to be the Representative for all purposes of this Agreement. The newly-appointed Representative
shall notify the Company, the Rights Agent and any other appropriate person in writing of his or her appointment, provide evidence that
the Acting Holders approved such appointment and provide appropriate contact information for purposes of this Agreement. The Company and
the Rights Agent shall be entitled to rely upon, without independent investigation, the identity and validity of such newly-appointed
Representative as set forth in such written notice. In the event that within thirty (30) days after the Representative dies, becomes unable
to perform his or her responsibilities hereunder or resigns or is removed from such position and no successor Representative has been
so selected, the Company shall cause the Rights Agent to notify the person holding the largest quantity of the outstanding CVRs (and who
is not the Company or any Affiliate of the Company) that such person is the successor Representative, and shall be the successor Representative
hereunder. If such person notifies the Rights Agent in writing that such person declines to serve, the Rights Agent shall forthwith notify
the person holding the next-largest quantity of the outstanding CVRs (and who is not the Company or any Affiliate of the Company) that
such next-largest-quantity person is the successor Representative, and such next-largest-quantity person shall be the successor Representative
hereunder. The Holders are intended third party beneficiaries of this Section 5.06. If a successor Representative is not appointed
pursuant to the preceding procedure within sixty (60) days after the Representative dies, becomes unable to perform his or her responsibilities
hereunder or resigns or is removed from such position, the Company shall appoint a successor Representative.
