of any moneys held in such Funds, or use or direct the use of the proceeds of the Bonds, in a manner or to such an extent that
the Bonds will constitute arbitrage bonds under Section 148 of the Code.


 


The Company shall provide
the Issuer with a certificate of an appropriate officer, employee or agent of or consultant to the Company for inclusion in the
transcript of proceedings for the Bonds, setting forth the reasonable expectations of the Company on the date of delivery of and
payment for the Bonds regarding the amount and use of the proceeds of the Bonds and the facts, estimates and circumstances on which

The Company agrees
that at no time shall any funds constituting gross proceeds of the Bonds be used in any manner to cause or result in a prohibited
payment under applicable regulations pertaining to, or in any other fashion as would constitute failure of compliance with, Section 148
of the Code.


 


If there is any amount
required to be paid to the United States pursuant to Section 148(f) of the Code or Section 5.03 of the Indenture,
the Company shall pay such amount to the Trustee for deposit to the Rebate Fund created under Section 5.03 of the Indenture,
who will, acting on behalf of the Company, submit the payment to the United States.


 


Section 3.05.
Purchase and Sale of Project Facilities. (a) In consideration of the issuance and sale of the Bonds, the Company hereby,
and by conveyance of even date herewith, assigns, conveys and transfers to the Issuer all of its right, title, and interest
in and to the portion of the Project Facilities to which the Company has title at the time of issuance of the Bonds. The
Company further hereby assigns, conveys and transfers to the Issuer all of its right, title and interest in and to each
discrete portion of the Project Facilities (except for portions of the Project Facilities acquired from the Issuer) as such
portion is acquired, constructed and installed in accordance with this Agreement, with the result that title to each such
portion of the Project Facilities automatically shall vest in the Issuer as the same is in the process of being acquired,
constructed and installed in accordance with this Agreement. Such transfer shall be made subject to Permitted Encumbrances.
Neither the Issuer nor the City shall be responsible or liable in any manner for any claims, losses, damages, penalties,
costs, taxes, assessments, charges or fines with respect to the acquisition, construction, installation, improvement,
operation, maintenance or ownership of the Project Facilities or any portion thereof (including any environmental issues and
matters) and the Company shall indemnify the Issuer and pay all expenses applicable to or arising therefrom as provided in
Section 5.02.


 






    8


     


    

 


(b) The Issuer does
hereby, and by conveyance of even date herewith, sell and convey to the Company and the Company does hereby purchase and reacquire
from the Issuer all of its right, title and interest in and to the portion of the Project Facilities to which the Issuer acquires
title as of the date of issuance of the Bonds. The Issuer does further hereby sell and convey to the Company, and the Company does
hereby purchase and reacquire from the Issuer, all of its right, title and interest in and to each discrete portion of the Project
Facilities as such portion is acquired, constructed and installed in accordance with this Agreement. Upon completion of such acquisition,
construction and installation of each discrete portion of the Project Facilities in accordance with this Agreement, all of the
Issuer's right, title and interest of every nature whatsoever in and to such portion of the Project Facilities automatically shall
vest irrevocably in the Company without the necessity of the execution of any conveyance by the Issuer, and such transaction shall
result in the automatic sale and delivery of such portion of the Project Facilities by the Issuer to the Company, and the vesting
of title to such portion of the Project Facilities in the Company, in consideration for the agreement of the Company to make, or
cause to be made, the Installment Payments and other payments and indemnities required under this Agreement. Such transfer shall
be made subject to Permitted Encumbrances. Upon the transfer by the Issuer to the Company of the Project Facilities, the Issuer
shall have no further right, title or interest in or to the Project Facilities. The Issuer shall execute and deliver to the Company
such deeds, assignments, bills of sale or other evidence of the transfer of its interest in the Project Facilities to be transferred
pursuant hereto as the Company may from time to time reasonably request; all at the expense of the Company, provided, however,
that irrespective of any failure to deliver such deeds, assignments, bills of sale or other evidence, the Project Facilities shall
be deemed transferred and vested as herein provided without any further act required of the Company or the Issuer. The Company
will pay all expenses applicable to or arising from said transfer of title. The Company shall be entitled to sole and exclusive
possession of the Project Facilities from the date of vesting of title thereto in the Company as herein provided. In connection
with all sales and conveyances by the Issuer to the Company of the Project Facilities hereunder, the Company acknowledges that
the Issuer makes no warranty, either express or implied, nor offers any assurances that the Project Facilities will be suitable
for the Company’s purposes or needs.


 


(c) In the event that
all of the principal of the Bonds shall be redeemed prior to scheduled maturity or become due and payable pursuant to the provisions
of the Indenture, because of the acceleration of the scheduled maturity of such Bonds for any reason, and such event should occur
prior to the vesting of title to the Project Facilities in the Company, the Issuer shall, upon redemption of such Bonds or full
payment by the Company of all Installment Payments due because of such acceleration of maturity and at the expense of the Company,
deliver to the Company such documents as will be reasonably required to convey to the Company of all of the Issuer's right, title
and interest in and to the Project Facilities or parts thereof which were acquired, constructed or improved with funds from the

PAYMENT PROVISIONS


 


Section 4.01. Installment
Payments. As and for the purchase price of the Project Facilities, on each date on which any payment of principal of or interest
on the Bonds shall become due (whether at maturity, or upon redemption or acceleration or otherwise), the Company will pay or cause
to be paid to the Trustee, for the account of the Issuer and in immediately available funds, as an installment of such purchase
price, an amount which, together with other moneys held by the Trustee under the Indenture and available therefor, will enable
the Trustee to make such payment of principal of or interest on the Bonds to the Bondholders in full in a timely manner (“Installment
Payments”).


 


In furtherance of the
foregoing, so long as any Bonds are outstanding, the Company will pay or cause to be paid all amounts required to prevent any deficiency
or default in any payment with respect to the Bonds, including any deficiency caused by an act or failure to act by the Trustee,
the Company, the Issuer or any other Person.


 


The Issuer assigns
all amounts payable under this Section by the Company to the Trustee pursuant to the Indenture for the benefit of the Bondholders.
The Company assents to such assignment. Accordingly, the Company will pay directly to the Trustee at its designated office all
payments payable by the Company pursuant to this Section.


 


Section 4.02. Additional
Payments. The Company will also pay the following upon demand after receipt of a bill therefor:


 


(a)       The
reasonable and documented out-of-pocket fees and expenses, including reasonable attorneys’ fees, of the Issuer incurred
in connection with this Agreement, the Indenture, the Tax Regulatory Agreement and the Bonds, and the making of any amendment or
supplement thereto, including, but not limited to: (i) those described in Section 3.06 (which includes the fees and expenses
associated with the initial drafting, execution and delivery of this Agreement, the Indenture, the Tax Regulatory Agreement and
the Bonds), (ii) those described in Section 7.04 and (iii) any other payments or indemnification required under
Section 5.02; and


 


(b)       The
reasonable and documented out-of-pocket fees and expenses of the Trustee under the Indenture, including reasonable
attorneys’ fees, for any services rendered by it under the Indenture, including those described in Section 7.04 in
connection with inquiring into or enforcing the performance of the Company’s obligations hereunder, and any other
payments or indemnification required under Section 5.02, such fees, expenses and payments to be paid directly to the
Trustee for its own account as and when such fees and expenses become due and payable.


 






    10


     


    

 


The Company further
agrees to pay all reasonable and documented out-of-pocket costs and expenses (including reasonable attorney’s fees
and expenses) of the Issuer and the Trustee incurred after the initial issuance of the Bonds in the preparation of any responses,
reproduction of any documentation or participation in any inquiries, investigations or audits from any Person solely or primarily
in connection with the Bonds, including without limitation, the Internal Revenue Service, the Securities Exchange Commission or
other governmental agency.


 


Section 4.03. Deposit
of Moneys in Bond Fund; Moneys for Purchase and Redemption. The Company may at any time deposit moneys in the Bond Fund, without
premium or penalty, to be held by the Trustee for application to Installment Payments not yet due and payable, and the Issuer agrees
that the Trustee shall accept such deposits when tendered by the Company. Such deposits shall be credited against the Installment
Payments, or any portion thereof, in the order of their due dates. Such deposits shall not in any way alter or suspend the obligations
of the Company under this Agreement during the term hereof as provided in Section 8.01.


 


In addition, the Company
may deliver moneys to the Trustee for use for the optional redemption of Bonds pursuant to Sections 6.01 and 6.02 and shall
deliver moneys to the Trustee for mandatory redemption of Bonds as required by Section 4.02(c) of the Indenture.


 


Section 4.04. Obligations
Unconditional. The obligations of the Company to make payments required by Sections 4.01, 4.02 and 4.03 and to perform
its other agreements contained herein shall be absolute and unconditional, and the Company shall make such payments without abatement,
diminution or deduction regardless of any cause or circumstance whatsoever, including, without limitation, damage, destruction
or condemnation of the Project Facilities (the risk of which shall be borne exclusively by the Company).


 


Section 4.05. Assignment
by Company. Rights granted to the Company under this Agreement may be assigned in whole or in part by the Company without the
necessity of obtaining the consent of the Issuer or the Trustee, subject, however, to each of the following conditions:


 


(a)       unless
waived by the Issuer or the Trustee, the Company shall notify the Issuer and the Trustee in writing of the identity of any assignee
at least 30 days prior to the effective date of such assignment;


 


(b)       no
assignment shall relieve the Company from primary liability hereunder for its obligations hereunder, and the Company shall continue
to remain primarily liable for the payment of the Installment Payments and Additional Payments and for performance and observance
of the agreements on its part herein provided to be performed and observed by it;


 






    11


     


    

 





(c)       any
assignment from the Company must retain for the Company such rights and interests as will permit it to perform its obligations
under this Agreement;


 


(d)       the
Company shall, within 30 days after execution thereof, furnish or cause to be furnished to the Issuer and the Trustee a true
and complete copy of each such assignment; and


 


(e)       any
assignment from the Company shall not materially impair fulfillment of the purposes to be accomplished by operation of the Project
Facilities as a project, the financing of which is permitted under the Act.


 


Section 4.06. Assignment
by Issuer. The Issuer will assign its rights under and interest to this Agreement (except for the Unassigned Issuer’s
Rights) to the Trustee pursuant to the Indenture as security for the payment of the Bonds. Otherwise, the Issuer will not sell,
assign or otherwise dispose of its rights under or interest in this Agreement nor create or permit to exist any lien, encumbrance
or security interest thereon.


 


Section 4.07. Limitation
of Issuer’s Liability. The Bonds are special, limited obligations of the Issuer and the Bond Service Charges thereon
shall be paid equally and ratably by the Issuer solely from the Pledged Receipts, including the Installment Payments to be made
by the Company under this Agreement. The Bonds shall never constitute A CHARGE AGAINST
THE GENERAL CREDIT OF THE ISSUER OR an indebtedness of the City, the COUNTY OR THE State or any political subdivision thereof within
the meaning of any State constitutional or statutory provision nor constitute or give rise to a pecuniary liability of the City,
THE COUNTY or the State or a charge against their general credit or taxing powers. The Bonds shall not constitute or create
any debt or liability of the City, the County or the State or any other political subdivision thereof, or a loan of the credit
of the City, the County or the State or any other political subdivision. The issuance of the Bonds shall not directly, indirectly
or contingently obligate the City, the County or the State or any political subdivision thereof to levy or to pledge any form of
taxation whatsoever therefor, or to make any appropriation for the payment thereof. The Issuer has no taxing power.

such grant, sale or lease shall relieve the Company from its obligations under this Agreement;


 


(b)       the
Company shall retain such rights and interests as will permit it to comply with its obligations under this Agreement;


 


(c)       no

    12


     


    

 





(d)       the
Company shall receive an Opinion of Nationally Recognized Bond Counsel to the effect that such grant, sale or lease does not have
an adverse effect upon the tax-exempt status of the interest on the Bonds.


 


Section 5.02. Indemnification
of Issuer and Trustee. The Company will indemnify and hold the Issuer and its members, directors, officers, elected officials,
employees, agents and representatives free and harmless from, and will indemnify and hold the Trustee and its officers, employees
and agents free and harmless from, any loss, claim, damage, tax, penalty, liability, disbursement, litigation expenses, attorneys’
fees and expenses or court costs arising out of, or in any way relating to, the execution or performance of the Indenture, this
Agreement, the Bond Purchase Agreement or any other documents in connection therewith, or any other cause and/or matter whatsoever
pertaining to the Project Facilities (including without limitation any loss, claim, damage, tax penalty, liability, disbursement,
litigation expenses, attorneys’ fees and expenses or court costs asserted or arising under any federal, state or local statute,
law, ordinance, code, rule, regulation, order or decree regulating or relating to or imposing liability or standards of conduct
concerning any hazardous, toxic or dangerous waste, substance or material), or the Bonds, including the issuance or sale of the
Bonds, or the failure to issue or sell the Bonds, actions taken under the Bonds, the Indenture, this Agreement, the Bond Purchase
Agreement or any other documents in connection therewith or any other cause whatsoever pertaining to the Project Facilities, except
in any case as a result of the gross negligence or willful misconduct of the Issuer or any Issuer indemnified party or as a result
of the negligence or willful misconduct of the Trustee or any Trustee indemnified party.


 


The Company may, at
its cost and in its name or in the name of the Issuer or the Trustee, as the case may be, prosecute or take any other action involving
third persons which the Company deems necessary in order to ensure or protect the Company’s rights under this Agreement;
in such event, the Issuer or the Trustee, as the case may be, will reasonably cooperate with the Company, but at the sole expense
of the Company.


 


In case any
actions or proceedings are brought against the Issuer or the Trustee in respect of which indemnity may be sought hereunder,
the party seeking indemnity shall promptly (but in any event within 15 days of receipt of service by such party) give
notice of that action or proceeding to the Company enclosing copies of all papers served, and the Company, upon receipt of
that notice, shall have the obligation and the right to assume the defense of the action or proceeding; provided, that
failure of a party to give that notice shall not relieve the Company from any of its obligations under this Section unless
that failure materially prejudices the defense of the action or proceeding by the Company. Any such indemnified party shall
have the right to employ separate counsel in any such action or proceeding and participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such indemnified party, unless: (i) the employment of such
counsel has been specifically authorized by the Company, or (ii) the parties to any such action or proceeding include
both the indemnified party and the Company and representation of both the indemnified party and the Company would not be
appropriate due to actual or potential conflicts of interest, as determined in good faith by the Company. The Company shall
not be liable for any settlement of any such action or proceeding effected without its written consent (which shall not be
unreasonably withheld or delayed), but if settled with the consent of the Company, or if there be a final judgment for the
plaintiff in any such action, the Company agrees to indemnify and hold harmless any such indemnified party from and against
any loss or liability by reason of such settlement or judgment.

contained herein to the contrary, the Company shall not be obligated to indemnify or hold harmless the Issuer or its members, directors,
officers, elected officials, employees, agents and representatives for their gross negligence or willful misconduct, nor shall
the Company be obligated to indemnify or hold harmless the Trustee or its officers, employees and agents for their negligence or
willful misconduct.


 


The foregoing indemnification
of the Issuer is intended to be interpreted broadly and shall include its members, directors, officers, elected officials, employees,
agents and representatives, shall be enforceable by the Issuer to the full extent permitted by law, shall survive beyond the termination
or discharge of the Indenture or payment of the Bonds and the limitation on indemnification described above with respect to the
gross negligence or willful misconduct of the Issuer or any Issuer indemnified party shall apply only in cases in which any loss,
claim, damage, tax, penalty, liability, disbursement, litigation expense, attorneys’ fee or expenses or court cost of the
Issuer or any such Issuer indemnified party is adjudicated to have resulted from the gross negligence or willful misconduct of
the Issuer or such Issuer indemnified party.


 


The foregoing indemnification
of the Trustee is intended to and shall include its officers, employees and agents, shall be enforceable by the Trustee to the
full extent permitted by law, and shall survive beyond the termination or discharge of the Indenture or payment of the Bonds.


 


Section 5.03. Company
Not to Adversely Affect Exclusion from Gross Income of Interest on Bonds. The Company hereby represents that it has taken and
caused to be taken, and covenants that it will take and cause to be taken, all actions that may be required of it, alone or in
conjunction with the Issuer, for the interest on the Bonds to be and to remain excludable from gross income for federal income
tax purposes, and represents that it has not taken or permitted to be taken on its behalf, and covenants that it will not take
or permit to be taken on its behalf, any action that would adversely affect such excludability under the provisions of the Code.


 


The Company also covenants
that it will restrict the investment and reinvestment and the use of the proceeds of the Bonds in such manner and to such extent,
if any, as may be necessary so that the Bonds will not constitute arbitrage bonds under Section 148 of the Code.


 


The Company hereby
covenants that on or before the 90th day following the date any of the Project Facilities are no longer being operated
as qualifying exempt facilities under the Code (unless such facilities have simply ceased to be operated), or such later date as
provided in the Indenture, the Company shall cause a related amount of Bonds to be redeemed pursuant to the Extraordinary Mandatory
Redemption provision of the Bonds as provided in Section 4.02(c) of the Indenture.

Section 5.04. Company
to Maintain its Existence; Mergers or Consolidations. The Company covenants that it will not merge or consolidate with any
other legal entity or sell or convey all or substantially all of its assets to any other legal entity, except that the Company
may merge or consolidate with, or sell or convey all or substantially all of its assets to any other legal entity, provided that
(a) the Company shall be the continuing legal entity or the successor legal entity (if other than the Company) shall be a
legal entity organized and existing under the laws of the United States of America or a state thereof, qualified to do business
in the State, and such legal entity shall expressly assume the due and punctual payment of the Installment Payments and the Additional
Payments hereunder in order to ensure timely and proper payment of the principal of and interest on all the Bonds, according to
their tenor, and the due and punctual performance and observance of all the covenants and conditions of this Agreement to be performed
by the Company (an “Assumption Agreement”) and (b) the Company or such successor legal entity, as the
case may be, shall not, immediately after such merger or consolidation, or such sale or conveyance, be in default in the performance
of any such covenant or condition and no event which with the lapse of time, the giving of notice or both would constitute an
Event of Default under Section 7.01 shall have occurred and be continuing.


 


The Company shall,
within 30 days after the execution of an Assumption Agreement, furnish to the Issuer and the Trustee an executed copy of such Assumption
Agreement and appropriate documentation demonstrating that the successor legal entity (if other than the Company) is organized
and existing under the laws of the United States of America or a state thereof and is qualified to do business in the State.


 


In the case of any
such consolidation, merger, sale or conveyance and upon the assumption by the successor legal entity of the obligations under this
Agreement and on the Bonds in accordance with the foregoing, such successor legal entity shall succeed to and be substituted for
the Company, with the same effect as if it had been named herein as a party hereto, and the Company shall thereupon be relieved
of any further obligations or liabilities hereunder and upon the Bonds and the Company as the predecessor legal entity may thereupon
or at any time thereafter be dissolved, wound-up or liquidated.


 


Section 5.05. Reports
and Audits. The Company shall as soon as practicable but in no event later than six months after the end of each of its fiscal
years, file with the Trustee and the Issuer, audited financial statements of the Company prepared as of the end of such fiscal
year; provided that the Company may satisfy this requirement by its filing of such information with the Securities and Exchange
Commission (www.sec.gov) and the Municipal Securities Rulemaking Board (emma.msrb.org) in accordance with their respective filing
requirements. Notwithstanding the above provisions of this Section, the Company shall provide a written copy of the Company’s
most recent audited financial statements to the Issuer upon the written request of the Issuer.


 


Section 5.06. Insurance.
The Company shall maintain, or cause to be maintained, insurance covering the Project Facilities against such risks and in such
amounts as is customarily carried by similar industries as the Company, and which insurance may be, in whole or in part, self-insurance.

provision for payment thereof having been made in accordance with the provisions of the Indenture): (a) in accordance
with Article IX of the Indenture, by paying to the Trustee an amount which, when added to the amount on deposit in the
funds established under the Indenture and available therefor, will be sufficient to pay, retire and, pursuant to the

EVENTS OF DEFAULT AND REMEDIES


 


Section 7.01. Events
of Default. Each of the following shall be an Event of Default:





 


(a)       The
Company shall fail to pay the amounts required to be paid under Section 4.01 or 4.02 on the dates specified therein;


 


(b)       Failure
by the Company to observe and perform any covenant, condition or agreement on its part to be observed or performed under this Agreement,
other than as referred to in Section 7.01(a), (other than certain representations, warranties and covenants regarding various
matters relating to the tax status of the interest on the Bonds) for a period of 60 days after written notice specifying such
failure and requesting that it be remedied shall have been given to the Company by the Issuer or the Trustee, unless the Issuer
and the Trustee shall agree in writing to an extension of such time prior to its expiration; provided, however, if the failure
stated in the notice cannot be corrected within the applicable period, it shall not constitute an Event of Default if corrective
action is instituted by the Company within the applicable period and is being diligently pursued until the default is corrected;


 


(c)       The
dissolution or liquidation of the Company or the voluntary initiation by the Company of any proceeding under any federal or state
law relating to bankruptcy, insolvency, arrangement, reorganization, readjustment of debt or any other form of debtor relief, or
the initiation against the Company of any such proceeding which shall remain undismissed for 60 days, or failure by the Company
to promptly have discharged any execution, garnishment or attachment of such consequence as would materially impair the ability
of the Company to carry on its operations, or assignment by the Company for the benefit of creditors, or the entry by the Company
into an agreement of composition with creditors or the failure generally by the Company to pay its debts as they become due; or


 


(d)       The
occurrence of an Event of Default as defined in the Indenture.


 


Any declaration of
default under subparagraph (c) and the exercise of remedies upon any such declaration will be subject to any applicable limitations
of federal bankruptcy law affecting or precluding that declaration or exercise during the pendency of or immediately following
any bankruptcy, liquidation or reorganization proceedings.


 


Section 7.02. Remedies
on Default. Whenever an Event of Default shall have happened and be existing, any one or more of the following remedial steps
may be taken:


 


(a)       if
acceleration of the principal amount of the Bonds has been declared pursuant to Section 7.03 of the Indenture, the Issuer
or the Trustee shall declare all Installment Payments to be immediately due and payable, whereupon the same shall become immediately
due and payable; or


 


(b)       the
Issuer or the Trustee may pursue all remedies now or hereafter existing at law or in equity to collect all amounts then due and
thereafter to become due under this Agreement or to enforce the performance and observance of any other obligation or agreement
of the Company under those instruments.


 


Notwithstanding
the foregoing, the Trustee shall not be obligated to take any step that in its reasonable opinion will or might cause it to
expend time or money or otherwise incur liability unless and until a satisfactory indemnity bond has been furnished to the
Trustee at no cost or expense to it. Any amounts collected pursuant to action taken under this Section (except for amounts
payable directly to the Issuer or the Trustee pursuant to Section 3.06, 4.02, 5.02 or 7.04) shall be paid into the Bond
Fund and applied in accordance with the provisions of the Indenture or, if the Outstanding Bonds have been paid and
discharged in accordance with the provisions of the Indenture, shall be paid as provided in Section 9.01 of the
Indenture for transfers of remaining amounts in the Bond Fund.


 






    17


     


    

 


The provisions of this
Section are subject to the further limitation that the rescission by the Trustee of its declaration that all of the Bonds are immediately
due and payable also shall constitute an annulment of any corresponding declaration made pursuant to paragraph (a) of this
Section and a waiver and rescission of the consequences of that declaration and of the Event of Default with respect to which that
declaration has been made, provided that no such waiver or rescission shall extend to or affect any subsequent or other default
or impair any right consequent thereon.


 


Section 7.03. No
Remedy Exclusive. No remedy conferred upon or reserved to the Issuer or the Trustee by this Agreement is intended to be exclusive
of any other available remedy or remedies, but each and every remedy shall be cumulative and shall be in addition to every other
remedy given under this Agreement, now or hereafter existing at law, in equity or by statute. No delay or omission to exercise
any right or power accruing upon any default shall impair that right or power or shall be construed to be a waiver thereof, but
any such right and power may be exercised from time to time and as often as may be deemed expedient. In order to entitle the Issuer
or the Trustee to exercise any remedy reserved to it in this Article, it shall not be necessary to give any notice, other than
any notice required by law or for which express provision is made herein.


 


Section 7.04. Agreement
to Pay Fees and Expenses. If an Event of Default should occur and the Issuer or the Trustee should incur expenses, including
attorneys’ fees, in connection with the enforcement of this Agreement or the collection of sums due hereunder, the Company
shall reimburse the Issuer and the Trustee, as applicable, for the reasonable and documented out-of-pocket expenses so incurred
upon demand.


 


Section 7.05. No
Waiver. No failure by the Issuer or the Trustee to insist upon the performance by the Company of any provision hereof shall
constitute a waiver of their right to performance and no express waiver shall be deemed to apply to any other existing or subsequent
right to remedy the failure by the Company to observe or comply with any provision hereof.


 


Section 7.06. Notice
of Default. The Company shall notify a Responsible Officer the Trustee immediately and in writing if it becomes aware of the
occurrence of any Event of Default hereunder or of any fact, condition or event which, with the giving of notice or passage of
time or both, would become an Event of Default.
