COMPLETION OF
THE PROJECTS;

ISSUANCE OF THE BONDS

 

Section
3.1.Acquisition, Construction and Installation. The Company represents and agrees that it and any other public utility
company which owns any undivided interest in the Project Facilities with the Company as tenants-in-common have caused the Projects
to be acquired, constructed and installed on the Project Sites in accordance with the Project Descriptions and in conformance
with all applicable, valid and enforceable (i) zoning, planning, building, environmental and other similar regulations of all
governmental authorities having jurisdiction over the Projects and (ii) permits, variances and orders issued in respect of the
Projects by EPA, noncompliance with which would have a material adverse effect on the Company’s ability to operate and maintain
the Projects or to perform its obligations hereunder, provided that the Company reserves the right to contest in good faith any
such regulations, permits, variances or orders. The proceeds derived from the Original Bonds and the Refunded Bonds, including
any investment thereof, were expended in accordance with the trust indentures and the loan agreements relating to the Original
Bonds and the Refunded Bonds.

 

Section
3.2.Project Descriptions. The Project Descriptions may be changed from time to time by, or with the consent of, the
Company provided that any such change shall also be filed with the Issuer and the Trustee and provided further that no change
in the Project Descriptions shall materially change the function of the Project Facilities unless the Trustee shall have received
(i) an Engineer's certificate that such changes will not impair the significance or character of the Project Facilities as Air
Quality Facilities and (ii) an Opinion of Bond Counsel or ruling of the Internal Revenue Service to the effect that such amendment
will not adversely affect the exclusion of interest on the Bonds from gross income for federal income tax purposes.

 

Section
3.3.Issuance of the Bonds; Application of Proceeds. To provide funds to make the Loan to the Company to assist the
Company in the refunding of the Refunded Bonds, the Issuer will issue, sell and deliver the Bonds to the Purchasers. The Bonds
will be issued pursuant to the Indenture in the aggregate principal amount, will bear interest, will mature and will be subject
to redemption as set forth therein. The Company hereby approves the terms and conditions of the Indenture and the Bonds, and the
terms and conditions under which the Bonds will be issued, sold and delivered. The Company, for the benefit of the Issuer, the
Trustee and each Bondholder, shall do and perform all acts and things required or contemplated in the Indenture to be done or
performed by the Company.

 

The proceeds from the
sale of the Bonds shall be loaned to the Company to assist the Company in the refunding of the Refunded Bonds. Those proceeds shall
be deposited in the Refunding Fund with all investment earnings thereon being credited to the Refunding Fund and applied in accordance
with Section 5.02 of the Indenture.

 

Pursuant to Section 5.02
of the Indenture, on the Redemption Date, all moneys in the Refunding Fund shall be transferred by the Trustee to the Refunded
Bonds Trustee for deposit in the Series 2008A Company Account of the bond fund created in the Series 2008A Indenture and the Series
2008B Company Account of the bond fund created in the Series 2008B Indenture, respectively, in the manner provided therein. Further,
in accordance with said Section 5.02 of the Indenture, such funds will be applied solely and exclusively by the Refunded Bonds
Trustee to reimburse the credit facility issuer for draws on the Series 2008A Credit Facility and the Series 2008B Credit Facility
used to redeem the Refunded Bonds on the Redemption Date. Any remaining reimbursement due to the Credit Facility Issuer after the
application of all such moneys shall be paid from moneys provided by the Company.

 

    	10

    	 

    

 

Pending disbursement
pursuant to this Section, the proceeds so deposited in the Refunding Fund, together with any investment earnings thereon, shall
constitute a part of the Revenues assigned by the Issuer to the Trustee for the payment of Bond Service Charges.

 

The Company acknowledges
that the proceeds of the Bonds (including any interest income thereon) may be insufficient to pay the full costs of refunding the
Refunded Bonds and that the Issuer has made no representation or warranty with respect to the sufficiency thereof. The Company
further acknowledges that it is (and will remain after the issuance of the Bonds) obligated to, and hereby confirms that it will,
pay all costs of the redemption of the Refunded Bonds on the Redemption Date.

 

The Company and the Issuer
hereby confirm that the Refunded Bonds Trustee has been notified that the entire outstanding principal amount of the Refunded Bonds
is to be redeemed on the Redemption Date, at the redemption price of 100% of the principal amount thereof, plus interest accrued
to that date.

 

Section 3.4.Investment of Fund
Moneys. Moneys held as part of the Bond Fund, the Refunding Fund or the Rebate Fund shall be invested or reinvested by the
Trustee in Eligible Investments at the written direction of the Company pursuant to Section 5.05 of the Indenture. The Issuer (to
the extent it retained or retains direction or control) and the Company each hereby covenants that it will restrict that 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 shall provide
the Issuer with, and the Issuer may base its certificate and statement, each as authorized by the Bond Legislation, on 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 those expectations are based.

 

Section
3.5.Rebate Fund. To the extent required by Section 5.09 of the Indenture, within five days after the end of the fifth
Bond Year and every fifth Bond Year thereafter, and within five days after payment in full of all outstanding Bonds, the Company
shall calculate the amount of Excess Earnings as of the end of that Bond Year or the date of such payment and shall notify the
Trustee of that amount. If the amount then on deposit in the Rebate Fund created under the Indenture is less than the amount of
Excess Earnings (computed by taking into account the amount or amounts, if any, previously paid to the United States pursuant
to Section 5.09 of the Indenture and this Section), the Company shall, within five days after the date of the aforesaid calculation,
pay to the Trustee for deposit in the Rebate Fund an amount sufficient to cause the Rebate Fund to contain an amount equal to
the Excess Earnings. The obligation of the Company to make such payments shall remain in effect and be binding upon the Company
notwithstanding the release and discharge of the Indenture. The Company shall obtain and keep such records of the computations
made pursuant to this Section as are required under Section 148(f) of the Code.

any Paying Agent or any Authenticating Agent.

 

 

    	12

such conversion is made any references herein to the Auction Agent and the Broker-Dealer shall be ineffective. When the Bonds
bear interest at an Auction Rate, the Company also shall have the option to direct the change of Auction Dates and/or the length
of Auction Periods in accordance with the Indenture. To exercise such options, the Company shall give the written notice required
by the Indenture.

 

Section
4.8.Company's Obligation to Purchase Bonds. The Company hereby agrees to pay or cause to be paid to the Trustee or
the Paying Agent, on each day on which Bonds may be or are required to be tendered for purchase, amounts equal to the amounts
to be paid by the Trustee or the Paying Agent with respect to the Bonds tendered for purchase on such dates pursuant to Article

 

 

    	13

Agent, (B) moneys drawn under a Credit Facility, if any, for the purpose of paying such purchase price and (C) other moneys made
available by the Company, as set forth in Section 4.08(b)(ii) of the Indenture.

Company;

may wind up, voluntarily liquidate or dissolve any subsidiary if (A) such subsidiary is not a Significant Subsidiary (as defined
in Rule 1-02 of Regulation S-X promulgated under the Securities Act of 1933, as amended) and (B) the winding up, voluntary liquidation

to or death of or loss by any person that may be occasioned by any cause whatsoever pertaining to the construction, maintenance,
operation and use of the Project Facilities; (b) any breach or default on the part of the Company in the performance of any covenant
or agreement of the Company under this Agreement or any related document, or arising from any act or failure to act by the Company,
or any of its agents, contractors, servants, employees or licensees; (c) the authorization, issuance and sale of the Bonds, or
the subsequent remarketing or determination of the interest rate or rates on the Bonds, and the provision of any information furnished
in connection therewith concerning the Project Facilities or the Company (including, without limitation, any information furnished
by the Company for inclusion in any certifications made by the Issuer under Section 3.7 hereof or for inclusion in, or as a basis
for preparation of, the Form 8038 information statement to be filed by the Issuer; and (d) any claim or action or proceeding with
respect to the matters set forth in (a), (b) and (c) above brought thereon.

 

The Company agrees to
indemnify the Trustee (including any predecessor Trustee), the Paying Agent, the Remarketing Agent, the Auction Agent and the Registrar
(each hereinafter referred to in this section as an "indemnified party") for and to hold each of them harmless from and
against all losses, liabilities, obligations, damages, claims, costs and expenses of any kind or nature whatsoever (including the
compensation and expenses of their counsel) incurred without negligence or willful misconduct on the part of the indemnified party
arising out of, relating to or connected with the Indenture or the Auction Agreement, including, but not limited to, on account
of the Trustee’s acceptance or administration of the trusts created by, or the performance of its powers or duties under
the Indenture, or of any action taken or omitted to be taken by the indemnified party in accordance with the terms of this Agreement,
the Bonds or the Indenture or any action taken at the request of or with the consent of the Company, including the costs and expenses
of the indemnified party in defending itself against or investigating any claim, loss, or liability, action, suits or proceeding
brought in connection with the exercise or performance of any of its powers or duties under this Agreement, the Bonds or the Indenture.

 

In case any action or
proceeding is brought against the Issuer or an indemnified party in respect of which indemnity may be sought hereunder, the party
seeking indemnity promptly shall give notice of that action or proceeding to the Company, and the Company upon receipt of that
notice

 

 

    	17

    	 

    

 

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 prejudices
the defense of the action or proceeding by the Company. At its own expense, an indemnified party may employ separate counsel and
participate in the defense; provided, however, where it is reasonably determined by Issuer or indemnified parties to be ethically
inappropriate or that it would create an actual or potential conflict of interest for one firm to represent the interests of the
Issuer and any other indemnified party or parties, the Company shall, to the extent applicable, pay the Issuer's and the indemnified
parties’ legal expenses in connection with the Issuer's and the indemnified parties’ retention of separate counsel.
The Company shall not be liable for any settlement made without its consent.

 

The indemnification set
forth above is intended to and shall include the indemnification of all affected officials, directors, officers and employees and
agents of the Issuer, the Trustee, the Paying Agent, the Remarketing Agent, the Auction Agent and the Registrar, respectively.
That indemnification is intended to and shall be enforceable by the Issuer, the Trustee, the Paying Agent, the Remarketing Agent
and the Registrar, respectively, to the full extent permitted by law. Each of the Trustee and each indemnified Person not a party
to this Agreement is an express third party beneficiary of this Section 5.9 and shall have the right to enforce or pursue remedies
under the provisions hereof as fully as though an original party hereto.

has taken and caused to be taken and shall take and cause to be taken all actions that may be required of it for the interest
on the Bonds to be and remain excluded from the gross income of the Holders for federal income tax purposes, and 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
which, if taken, would adversely affect that exclusion under the provisions of the Code. Neither the Issuer nor the Company shall
cause any proceeds of the Bonds to be expended, except pursuant to the Indenture and this Agreement.

 

Section
5.11.Ownership of Projects; Use of Projects. The Issuer agrees that it does not have and shall not have any interest
in, title to or ownership of the Projects or the Project Sites. The Issuer does hereby covenant and agree that it will not take
any action, or cause any action to be taken on its behalf, during the term of this Agreement, other than pursuant to Article VII
of this Agreement or Article VII of the Indenture, to interfere with the Company’s ownership interest in the Projects or
to prevent the Company from having possession, custody, use and enjoyment of the Projects, except such action as is requested
by the Trustee in enforcing any remedies available to it under this Agreement or the Indenture.

 

Section

following conditions:

 

(a)No assignment
(other than pursuant to Section 5.8 or Section 5.13 hereof) shall relieve the Company from primary liability for any of its obligations
hereunder, and in the event of any such assignment the Company shall continue to remain primarily liable for the payment of the
Loan Payments and Additional Payments and for performance and observance of the agreements on its part herein provided to be performed
and observed by it.

 

(b)Any assignment
by the Company must retain for the Company such rights and interests as will permit it to perform its obligations under this Agreement,
and any assignee from the

 

 

    	18

    	 

    

 

Company shall assume the obligations of the Company hereunder to the extent of the interest assigned.

 

(c)The Company
shall furnish to the Issuer and the Trustee an Opinion of Bond Counsel addressed to the Issuer and the Trustee to the effect that
such assignment is authorized or permitted by the Act and will not adversely affect the exclusion from gross income of interest
on the Bonds.

 

(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 together with any instrument of assumption.

REDEMPTION

 

Section
6.1.Optional Redemption. Provided no Event of Default shall have occurred and be subsisting, at any time and from time
to time, the Company may deliver moneys to the Trustee in addition to Loan Payments or Additional Payments required to be made
and direct the Trustee to use the moneys so delivered for the purpose of redeeming Bonds called for optional redemption in accordance
with the applicable provisions of the Indenture providing for optional redemption at the redemption price stated in the Indenture.
Pending application for those purposes, any moneys so delivered shall be held by the Trustee in a special account in the Bond
Fund and delivery of those moneys shall not, except as set forth in Section 4.1 hereof, operate to abate or postpone Loan Payments
or Additional Payments otherwise becoming due or to alter or suspend any other obligations of the Company under this Agreement.

 

Section
6.2.Extraordinary Optional Redemption. The Company shall have, subject to the conditions hereinafter imposed, the option
during a Term Rate Period to direct the redemption of the Bonds in whole or in part in accordance with Section 4.01(a) of the
Indenture upon the occurrence of any of the following events:

 

(a)A Project
or a Generating Station shall have been damaged or destroyed to such an extent that (1) it cannot reasonably be expected to be
restored, within a period of six consecutive months, to the condition thereof immediately preceding such damage or destruction
or (2) the Company is reasonably expected to be prevented from carrying on its normal operations in connection therewith for a
period of six consecutive months.

 

(b)Title to,
or the temporary use of, all or a significant part of a Project or a Generating Station shall have been taken under the exercise
of the power of eminent domain (1) to such extent that it cannot reasonably be expected to be restored within a period of six consecutive
months to a condition of usefulness comparable to that existing prior to the taking or (2) to such an extent that the Company is
reasonably expected to be prevented from carrying on its normal operations in connection therewith for a period of six consecutive
months.

 

(c)As a result
of any changes in the Constitution of the State, the Constitution of the United States of America or any state or federal laws
or as a result of legislative or administrative action (whether state or federal) or by final decree, judgment or order of any
court or administrative body (whether state or federal) entered after any contest thereof by the Issuer or the Company in good
faith, this Agreement shall have become void or unenforceable or impossible of performance in accordance with the intent and purpose
of the parties as expressed in this Agreement.

 

(d)Unreasonable
burdens or excessive liabilities shall have been imposed upon the Issuer or the Company with respect to a Project or a Generating
Station or the operation thereof, including, without limitation, the imposition of federal, state or other ad valorem, property,
income or other taxes other than ad valorem

 

 

    	21

    	 

    

 

taxes at the rates presently levied upon privately owned property used for the same
general purpose as a Project or a Generating Station.

 

(e)Changes
in the economic availability of raw materials, operating supplies, energy sources or supplies or facilities (including, but not
limited to, facilities in connection with the disposal of industrial wastes) necessary for the operation of a Project or a Generating
Station for the Project Purposes occur or technological or other changes occur which the Company cannot reasonably overcome or
control and which in the Company’s reasonable judgment render a Project or a Generating Station uneconomic or obsolete for
the Project Purposes.

 

(f)Any court
or administrative body shall enter a judgment, order or decree, or shall take administrative action, requiring the Company to cease
all or any substantial part of its operations served by a Project or a Generating Station to such extent that the Company is or
will be prevented from carrying on its normal operations at a Project or a Generating Station for a period of six consecutive months.

 

(g)The termination
by the Company of operations at a Generating Station.

 

As used in this Section
6.2, the term “a Project” means the portion of the Project Facilities at a particular Generating Station.

 

The amount payable by
the Company in the event of its exercise of the option granted in this Section shall be the sum of the following:

 

(i)An amount
of money which, when added to the moneys and investments held to the credit of the Bond Fund, will be sufficient pursuant to the
provisions of the Indenture to pay, at a redemption price of 100% of the principal amount redeemed plus accrued and unpaid interest
to the redemption date, and discharge, the Outstanding Bonds then being redeemed on the earliest applicable redemption date, that
amount to be paid to the Trustee, plus

 

(ii)An amount
of money equal to the Additional Payments relating to those Bonds accrued and to accrue until actual final payment and redemption
of those Bonds, that amount or applicable portions thereof to be paid to the Trustee or to the Persons to whom those Additional
Payments are or will be due.

 

The requirement of (ii) above with respect
to Additional Payments to accrue may be met if provisions satisfactory to the Trustee and the Issuer are made for paying those
amounts as they accrue.

 

The rights and options
granted to the Company in this Section may be exercised whether or not the Company is in default hereunder; provided, that such
default will not relieve the Company from performing those actions which are necessary to exercise any such right or option granted
hereunder.

 

 

    	22

    	 

    

 

Section
6.3.Mandatory Redemption. The Company shall deliver to the Trustee the moneys needed to redeem the Bonds in accordance
with any mandatory redemption provisions relating thereto as may be set forth in Section 4.01(b) of the Indenture.

 

Section
6.4.Notice of Redemption. In order to exercise an option granted in, or to consummate a redemption required by, this
Article VI, the Company shall, within 180 days following the event authorizing the exercise of such option, or at any time during
the continuation of the condition referred to in paragraphs (c), (d) or (e) of Section 6.2 hereof, or at any time that optional
redemption of the Bonds is permitted under the Indenture as provided in Section 6.1 hereof, or promptly upon the occurrence of
a Determination of Taxability, give written notice to the Issuer, the Trustee and the Company Mortgage Trustee that it is exercising
its option to direct the redemption of Bonds, or that the redemption thereof is required by Section 4.01(b) of the Indenture due
to the occurrence of a Determination of Taxability, as the case may be, in accordance with the Agreement and the Indenture, and
shall specify therein the date on which such redemption is to be made, which date shall not be more than 180 days from the date
such notice is mailed. The Company shall make arrangements satisfactory to the Trustee for the giving of the required notice of
redemption to the Holders of the Bonds, in which arrangements the Issuer shall cooperate. The Company shall make arrangements
satisfactory to the Company Mortgage Trustee to effect a concurrent redemption of an equivalent principal amount of corresponding
First Mortgage Bonds under the Supplemental Mortgage Indenture.

 

Section
6.5.Actions by Issuer. Subject to Section 4.2 hereof, at the request of the Company or the Trustee, the Issuer shall
take all steps required of it under the applicable provisions of the Indenture or the Bonds to effect the redemption of all or
a portion of the Bonds pursuant to this Article VI.

 

Section 6.6.Concurrent
Discharging of First Mortgage Bonds. In the event any of the Bonds or portion thereof shall be paid and discharged, or deemed
to be paid and discharged, pursuant to any provisions of this Agreement and the Indenture, so that such Bonds or such portion thereof
are not thereafter outstanding within the meaning of the Indenture, a like principal amount of corresponding First Mortgage Bonds
shall be deemed fully paid for purposes of this Agreement and to such extent the obligations of the Company hereunder shall be
deemed terminated.

ARTICLE VII

 

EVENTS OF DEFAULT AND REMEDIES

 

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

 

(a)The occurrence
of an event of default as defined in Section 7.01 (a), (b), (c), (d) or (g) of the Indenture;

 

(b)The Company
shall fail to observe and perform any other agreement, term or condition contained in this Agreement, other than such failure as
will have resulted in an event of default described in (a) above and the continuation of that failure for a period of 90 days after
notice thereof shall have been given to the Company by the Issuer or the Trustee, or for such longer period as the Issuer may agree
to in writing; provided, that such failure shall not constitute an Event of Default so long as the Company institutes curative
action within the applicable period and diligently pursues that action to completion within 150 days after the expiration of initial
cure period as determined above, or within such longer period as the Issuer may agree to in writing; and

 

(c)The occurrence
of a “completed default” as defined in Section 1 of Article Twelve of the Company Mortgage.

 

Notwithstanding the foregoing,
if, by reason of Force Majeure, the Company is unable to perform or observe any agreement, term or condition hereof which would
give rise to an Event of Default under subsection (b) hereof, the Company shall not be deemed in default during the continuance
of such inability. However, the Company shall promptly give written notice to the Trustee and the Issuer of the existence of an
event of Force Majeure and shall use its best efforts to remove the effects thereof; provided that the settlement of strikes or
other industrial disturbances shall be entirely within its discretion.

 

The exercise of remedies
hereunder shall 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
7.2.Remedies on Default. Whenever an Event of Default shall have happened and be subsisting, either or both of the
following remedial steps may be taken:

 

(a)The Issuer
or the Trustee may have access to, inspect, examine and make copies of the books, records, accounts and financial data of the Company,
only, however, insofar as they pertain to the Projects; or

 

(b)The Issuer
or the Trustee may pursue all remedies now or hereafter existing at law or in equity to recover all amounts, including all Loan
Payments and Additional Payments, then due and thereafter to become due under this Agreement (including Loan Payments due upon
tender for purchase or pursuant to acceleration), or to enforce the performance and observance of any other obligation or agreement
of the Company under this Agreement.

 

 

    	24

    	 

    

 

Notwithstanding the foregoing, the Issuer
shall not be obligated to take any step which in its 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 Issuer at no cost or expense to the Issuer.
Any amounts collected as Loan Payments or applicable to Loan Payments and any other amounts which would be applicable to payment
of Bond Service Charges collected pursuant to action taken under this Section 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 5.08 of the Indenture for transfers of remaining amounts in the Bond Fund.

 

The provisions of this
Section are subject to the further limitation that the rescission and annulment by the Trustee of its declaration that all of the
Bonds are immediately due and payable also shall constitute a rescission and annulment of any corresponding declaration made pursuant
to this Section and a rescission and annulment 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 rescission and annulment shall extend to or affect any subsequent
or other default or impair any right consequent thereon.

 

Section
7.3.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 such remedy shall be cumulative and shall be in
addition to every other remedy given under this Agreement, or 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 or 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
7.4.Agreement to Pay Attorneys' Fees and Expenses. If an Event of Default should occur and the Issuer or the Trustee
should incur expenses, including attorneys' fees and expenses, in connection with the enforcement of this Agreement or the collection
of sums due hereunder, the Company shall be required, to the extent permitted by law, to reimburse the Issuer and the Trustee,
as applicable, for the fees and expenses so incurred upon demand.

 

Section
7.5.No Waiver. No failure by the Issuer or the Trustee to insist upon the strict performance by the Company of any
provision hereof shall constitute a waiver of their right to strict 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
7.6.Notice of Default. The Company shall notify the Trustee immediately 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.

EXHIBIT A

 

DESCRIPTION OF AIR QUALITY FACILITIES

 

The Projects being
financed under this Agreement are described below and consist of any property or portion thereof used for the collection, storage,
treatment, utilization, processing, or final disposal of solid waste resulting from the supply, installation and construction of
Flue Gas Desulfurization Systems (FGDS) for the Units at the Generating Stations described below for the purpose of the removal
and disposal of flue gas particulates, sulfur dioxide (SO2) and nitrogen oxides (NOx). Removal of SO2 from
the flue gas exhaust is to be accomplished using a wet limestone FGDS scrubber technology. In that scrubber process, calcium carbonate
(reagent) neutralizes and absorbs the SO2 which produces a solid waste of primarily gypsum (waste reagent). The waste
reagent must be processed and disposed of as a solid waste. Use of the FGDS to remove sulfur dioxide from the flue gas stream creates
a solid waste that is collected, transported, processed and stored in a waste disposal or recycling facility.

 

1. PROJECT AT MIAMI FORT GENERATING STATION:

 

The Miami Fort Units
7 & 8 scrubber projects (collectively, the “Miami Fort Project”) are located at the Miami Fort Generating Station,
which is a coal-fired, steam powered electric generating station located in the southwest area of Hamilton County, Ohio (the “Miami
Fort Generating Station”). The Miami Fort Generating Station consists of five coal-fired boilers of various ages and ratings.
Units 7 & 8 are of similar size and rating, each being 525 MW. Units 7 and 8 are co-owned by the Company (36% ownership interest)
and Dynegy Inc. (“Dynegy”; 64% ownership interest)[1].
Dynegy is responsible for operation of the Miami Fort Generating Station. Air emission control regulations require removal and
disposal of combustion byproducts from the Miami Fort Generating Station, including from Units 7 & 8. These byproducts include
flue gas particulates and SO2.

 

The design of the Miami
Fort Project is based on two principal requirements. First, the Miami Fort Project must achieve the required level of the applicable
emission control. Second, the Miami Fort Project must produce a waste by-product that is suitable for solid waste disposal. The
Miami Fort Project includes the construction, expansion of and improvements to solid waste collection, transport, processing and
disposal facilities for the Miami Fort Generating Station related in whole or in part to removing SO2 from the flue
gas stream of Units 7 & 8 by means of the installation and use of the FGDS.

 

2. PROJECT AT KILLEN GENERATING STATION:

 

The Killen Unit 2 scrubber
project (the “Killen Project”) is located at the Killen Generating Station, which is a coal-fired, steam powered electric
generating station located near Manchester, Ohio in Adams County, Ohio (the “Killen Generating Station”). The Killen
Generating Station consists of one unit, Unit 2, which is rated at 600 MW. This unit is co-owned by the Company (67% ownership
interest) and Dynegy (33% ownership interest). The Company is responsible for operation of the Killen Generating Station. Air emission
control regulations require removal and disposal of combustion byproducts from the Killen Generating Station, including from Unit
2. These byproducts include flue gas particulates, SO2 and NOx.

The design of the Killen
Project is based on two principal requirements. First, the Killen Project must achieve the required level of the applicable emission
control. Second, the Killen Project must produce a waste by-product that is suitable for solid waste disposal. The Killen Project
includes the construction, expansion of, and improvements to solid waste collection, transport, processing and disposal facilities
for the Killen Generating Station related in whole or in part to removing SO2 from the flue gas stream of Unit 2 by
means of the installation and use of the FGDS.

 

3. PROJECT AT J.M. STUART GENERATING STATION:

 

The J.M. Stuart Station
Units 1-4 scrubber projects (collectively, the “Stuart Project”) are located at the J.M. Stuart Generating Station,
which is a coal-fired, steam powered electric generating station located near Aberdeen, Ohio in Brown and Adams Counties, Ohio
(the “Stuart Generating Station”). The Stuart Generating Station consists of four (4) coal-fired boilers each rated
at 585MW. This Stuart Generating Station is co-owned by the Company (35% ownership interest), Dynegy (39% ownership interest) and
Columbus Southern Power Company (“CSP”; 26% ownership interest). The Company is responsible for operation of the Stuart
Generating Station. Air emission control regulations require removal and disposal of combustion byproducts from all four (4) units
at the Stuart Generating Station. These byproducts include flue gas particulates, SO2 and NOx.

 

The design of the Stuart
Project is based on two principal requirements. First, the Stuart Project must achieve the required level of the applicable emission
control. Second, the Stuart Project must produce a waste by-product that is suitable for solid waste disposal. The Stuart Project
includes the construction, expansion of, and improvements to solid waste collection, transport, processing and disposal facilities
for the Stuart Generating Station related in whole or in part to removing SO2 from the flue gas stream of Units 1-4
by means of the installation and use of the FGDS.

 

4. PROJECT AT CONESVILLE GENERATING STATION:

 

The Conesville Unit
4 scrubber project (the “Conesville Project”) is located at the Conesville Generating Station, which is a coal-fired,
steam powered electric generating station located near Conesville, Ohio in Coshocton County, Ohio (the “Conesville Generating
Station”). The Conesville Generating Station consists of four (4) coal-fired boilers of various ages and ratings. Unit 4
is rated at 780 MW. This unit is co-owned by the Company (16.5% ownership interest), Dynegy (40% ownership interest) and CSP (43.5%
ownership interest). CSP is responsible for operation of the Conesville Generating Station. Air emission control regulations require
removal and disposal of combustion byproducts from the Conesville Generating Station, including from Unit 4. These byproducts include
flue gas particulates, SO2 and NOx.

 

The design of the
Conesville Project is based on two principal requirements. First, the Conesville Project must achieve the required level of the
applicable emission control. Second, the Conesville Project must produce a waste by-product that is suitable for solid waste disposal.
The Conesville Project includes the construction, expansion of, and improvements to solid waste collection, transport, processing
and disposal facilities for the Conesville Generating Station related in whole or in part to removing SO2 from the
flue gas stream of Unit 4 by means of the installation and use of the FGDS.

COMPLETION OF THE PROJECTS;

ISSUANCE OF THE BONDS

 

Section
3.1.Acquisition, Construction and Installation. The Company represents and agrees that it and any other public utility
company which owns any undivided interest in the Project Facilities with the Company as tenants-in-common have caused the Projects
to be acquired, constructed and installed on the Project Sites in accordance with the Project Descriptions and in conformance
with all applicable, valid and enforceable (i) zoning, planning, building, environmental and other similar regulations of all
governmental authorities having jurisdiction over the Projects and (ii) permits, variances and orders issued in respect of the
Projects by EPA, noncompliance with which would have a material adverse effect on the Company’s ability to operate and maintain
the Projects or to perform its obligations hereunder, provided that the Company reserves the right to contest in good faith any
such regulations, permits, variances or orders. The proceeds derived from the Original Bonds, including any investment thereof,
were expended in accordance with the trust indentures and the loan agreements relating to the Original Bonds.

 

Section
3.2.Project Descriptions. The Project Descriptions may be changed from time to time by, or with the consent of, the
Company provided that any such change shall also be filed with the Issuer and the Trustee and provided further that no change
in the Project Descriptions shall materially change the function of the Project Facilities unless the Trustee shall have received
(i) an Engineer's certificate that such changes will not impair the significance or character of the Project Facilities as Air
Quality Facilities and (ii) an Opinion of Bond Counsel or ruling of the Internal Revenue Service to the effect that such amendment
will not adversely affect the exclusion of interest on the Bonds from gross income for federal income tax purposes.

 

Section
3.3.Issuance of the Bonds; Application of Proceeds. To provide funds to make the Loan to the Company to assist the
Company in the refunding of the Refunded Bonds, the Issuer will issue, sell and deliver the Bonds to the Purchasers. The Bonds
will be issued pursuant to the Indenture in the aggregate principal amount, will bear interest, will mature and will be subject
to redemption as set forth therein. The Company hereby approves the terms and conditions of the Indenture and the Bonds, and the
terms and conditions under which the Bonds will be issued, sold and delivered. The Company, for the benefit of the Issuer, the
Trustee and each Bondholder, shall do and perform all acts and things required or contemplated in the Indenture to be done or
performed by the Company.

 

The proceeds from the
sale of the Bonds shall be loaned to the Company to assist the Company in the refunding of the Refunded Bonds. Those proceeds shall
be deposited in the Refunding Fund with all investment earnings thereon being credited to the Refunding Fund and applied in accordance
with Section 5.02 of the Indenture.

 

Pursuant to Section 5.02
of the Indenture, on the Redemption Date, all moneys in the Refunding Fund shall be transferred by the Trustee to the Refunded
Bonds Trustee for deposit in the  bond fund created in the Refunded Bonds Indenture.
In addition, the Company shall deposit with the Refunded Bonds Trustee on or prior to the Redemption Date funds which, together
with the proceeds of the Bonds, will be sufficient to redeem the Refunded Bonds on the Redemption Date.

 

Pending disbursement
pursuant to this Section, the proceeds so deposited in the Refunding Fund, together with any investment earnings thereon, shall
constitute a part of the Revenues assigned by the Issuer to the Trustee for the payment of Bond Service Charges.

 

    	11

    	 

    

The Company acknowledges
that the proceeds of the Bonds (including any interest income thereon) may be insufficient to pay the full costs of refunding the
Refunded Bonds and that the Issuer has made no representation or warranty with respect to the sufficiency thereof. The Company
further acknowledges that it is (and will remain after the issuance of the Bonds) obligated to, and hereby confirms that it will,
pay all costs of the redemption of the Refunded Bonds on the Redemption Date.

 

The Company and the Issuer
hereby confirm that the Refunded Bonds Trustee has been notified that the entire outstanding principal amount of the Refunded Bonds
is to be redeemed on the Redemption Date, at the redemption price of 100% of the principal amount thereof, plus interest accrued
to that date.

 

Section
3.4.Investment of Fund Moneys. Moneys held as part of the Bond Fund, the Refunding Fund or the Rebate Fund shall be
invested or reinvested by the Trustee in Eligible Investments at the written direction of the Company pursuant to Section 5.05
of the Indenture. The Issuer (to the extent it retained or retains direction or control) and the Company each hereby covenants
that it will restrict that 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 shall provide
the Issuer with, and the Issuer may base its certificate and statement, each as authorized by the Bond Legislation, on 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 those expectations are based.

 

Section 3.5.Rebate Fund.
To the extent required by Section 5.09 of the Indenture, within five days after the end of the fifth Bond Year and every fifth
Bond Year thereafter, and within five days after payment in full of all outstanding Bonds, the Company shall calculate the amount
of Excess Earnings as of the end of that Bond Year or the date of such payment and shall notify the Trustee of that amount. If
the amount then on deposit in the Rebate Fund created under the Indenture is less than the amount of Excess Earnings (computed
by taking into account the amount or amounts, if any, previously paid to the United States pursuant to Section 5.09 of the Indenture
and this Section), the Company shall, within five days after the date of the aforesaid calculation, pay to the Trustee for deposit
in the Rebate Fund an amount sufficient to cause the Rebate Fund to contain an amount equal to the Excess Earnings. The obligation
of the Company to make such payments shall remain in effect and be binding upon the Company notwithstanding the release and discharge
of the Indenture. The Company shall obtain and keep such records of the computations made pursuant to this Section as are required
under Section 148(f) of the Code.

bear interest at an Auction Rate, the Company also shall have the option to direct the change of Auction Dates and/or the length
of Auction Periods in accordance with the Indenture. To exercise such options, the Company shall give the written notice required
by the Indenture.

 

Section

the Paying Agent, on each day on which Bonds may be or are required to be tendered for purchase, amounts equal to the amounts
to be paid by the Trustee or the Paying Agent with respect to the Bonds tendered for purchase on such dates pursuant to Article

may wind up, voluntarily liquidate or dissolve any subsidiary if (A) such subsidiary is not a Significant Subsidiary (as defined
in Rule 1-02 of Regulation S-X promulgated under the Securities Act of 1933, as amended) and (B) the winding up, voluntary liquidation

any loss or damage to property or injury to or death of or loss by any person that may be occasioned by any cause whatsoever pertaining
to the construction, maintenance, operation and use of the Project Facilities; (b) any breach or default on the part of the Company
in the performance of any covenant or agreement of the Company under this Agreement or any related document, or arising from any
act or failure to act by the Company, or any of its agents, contractors, servants, employees or licensees; (c) the authorization,
issuance and sale of the Bonds, or the subsequent remarketing or determination of the interest rate or rates on the Bonds, and
the provision of any information furnished in connection therewith concerning the Project Facilities or the Company (including,
without limitation, any information furnished by the Company for inclusion in any certifications made by the Issuer under Section
3.7 hereof or for inclusion in, or as a basis for preparation of, the Form 8038 information statement to be filed by the Issuer;
and (d) any claim or action or proceeding with respect to the matters set forth in (a), (b) and (c) above brought thereon.

 

The Company agrees to
indemnify the Trustee (including any predecessor Trustee), the Paying Agent, the Remarketing Agent, the Auction Agent and the Registrar
(each hereinafter referred to in this section as an "indemnified party") for and to hold each of them harmless from and
against all losses, liabilities, obligations, damages, claims, costs and expenses of any kind or nature whatsoever (including the
compensation and expenses of their counsel) incurred without negligence or willful misconduct on the part of the indemnified party
arising out of, relating to or connected with the Indenture or the Auction Agreement, including, but not limited to, on account
of the Trustee’s acceptance or administration of the trusts created by, or the performance of its powers or duties under
the Indenture, or of any action taken or omitted to be taken by the indemnified party in accordance with the terms of this Agreement,
the Bonds or the Indenture or any action taken at the request of or with the consent of the Company, including the costs and expenses
of the indemnified party in defending itself against or investigating any claim, loss, or liability, action, suits or proceeding
brought in connection with the exercise or performance of any of its powers or duties under this Agreement, the Bonds or the Indenture.

 

In case any action or
proceeding is brought against the Issuer or an indemnified party in respect of which indemnity may be sought hereunder, the party
seeking indemnity promptly shall give notice of that action or proceeding to the Company, and the Company upon receipt of that
notice

 

    	18

    	 

    

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 prejudices the defense of the action or proceeding by
the Company. At its own expense, an indemnified party may employ separate counsel and participate in the defense; provided, however,
where it is reasonably determined by Issuer or indemnified parties to be ethically inappropriate or that it would create an actual
or potential conflict of interest for one firm to represent the interests of the Issuer and any other indemnified party or parties,
the Company shall, to the extent applicable, pay the Issuer's and the indemnified parties’ legal expenses in connection with
the Issuer's and the indemnified parties’ retention of separate counsel. The Company shall not be liable for any settlement
made without its consent.

 

The indemnification set
forth above is intended to and shall include the indemnification of all affected officials, directors, officers and employees and
agents of the Issuer, the Trustee, the Paying Agent, the Remarketing Agent, the Auction Agent and the Registrar, respectively.
That indemnification is intended to and shall be enforceable by the Issuer, the Trustee, the Paying Agent, the Remarketing Agent
and the Registrar, respectively, to the full extent permitted by law. Each of the Trustee and each indemnified Person not a party
to this Agreement is an express third party beneficiary of this Section 5.9 and shall have the right to enforce or pursue remedies
under the provisions hereof as fully as though an original party hereto.

 

Section
5.10.Issuer and Company Not to Adversely Affect Exclusion of Interest on Bonds From Gross Income For Federal Income Tax
Purposes. The Issuer, solely to the extent within its control, and the Company each hereby covenants and represents that it
has taken and caused to be taken and shall take and cause to be taken all actions that may be required of it for the interest
on the Bonds to be and remain excluded from the gross income of the Holders for federal income tax purposes, and 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
which, if taken, would adversely affect that exclusion under the provisions of the Code. Neither the Issuer nor the Company shall
cause any proceeds of the Bonds to be expended, except pursuant to the Indenture and this Agreement.

 

Section
5.11.Ownership of Projects; Use of Projects. The Issuer agrees that it does not have and shall not have any interest
in, title to or ownership of the Projects or the Project Sites. The Issuer does hereby covenant and agree that it will not take
any action, or cause any action to be taken on its behalf, during the term of this Agreement, other than pursuant to Article VII
of this Agreement or Article VII of the Indenture, to interfere with the Company’s ownership interest in the Projects or
to prevent the Company from having possession, custody, use and enjoyment of the Projects, except such action as is requested
by the Trustee in enforcing any remedies available to it under this Agreement or the Indenture.

 

Section

following conditions:

 

(a)No assignment
(other than pursuant to Section 5.8 or Section 5.13 hereof) shall relieve the Company from primary liability for any of its obligations
hereunder, and in the event of any such assignment the Company shall continue to remain primarily liable for the payment of the
Loan Payments and Additional Payments and for performance and observance of the agreements on its part herein provided to be performed
and observed by it.

 

(b)Any assignment
by the Company must retain for the Company such rights and interests as will permit it to perform its obligations under this Agreement,
and any assignee from the

 

    	19

Provided no Event of Default shall have occurred and be subsisting, at any time and from time to time, the Company may deliver
moneys to the Trustee in addition to Loan Payments or Additional Payments required to be made and direct the Trustee to use the
moneys so delivered for the purpose of redeeming Bonds called for optional redemption in accordance with the applicable provisions
of the Indenture providing for optional redemption at the redemption price stated in the Indenture. Pending application for those
purposes, any moneys so delivered shall be held by the Trustee in a special account in the Bond Fund and delivery of those moneys
shall not, except as set forth in Section 4.1 hereof, operate to abate or postpone Loan Payments or Additional Payments otherwise
becoming due or to alter or suspend any other obligations of the Company under this Agreement.

 

Section 6.2.Extraordinary Optional
Redemption. The Company shall have, subject to the conditions hereinafter imposed, the option during a Term Rate Period to
direct the redemption of the Bonds in whole or in part in accordance with Section 4.01(a) of the Indenture upon the occurrence
of any of the following events:

 

(a)A Project
or a Generating Station shall have been damaged or destroyed to such an extent that (1) it cannot reasonably be expected to be
restored, within a period of six consecutive months, to the condition thereof immediately preceding such damage or destruction
or (2) the Company is reasonably expected to be prevented from carrying on its normal operations in connection therewith for a
period of six consecutive months.

 

(b)Title to,
or the temporary use of, all or a significant part of a Project or a Generating Station shall have been taken under the exercise
of the power of eminent domain (1) to such extent that it cannot reasonably be expected to be restored within a period of six consecutive
months to a condition of usefulness comparable to that existing prior to the taking or (2) to such an extent that the Company is
reasonably expected to be prevented from carrying on its normal operations in connection therewith for a period of six consecutive
months.

 

(c)As a result
of any changes in the Constitution of the State, the Constitution of the United States of America or any state or federal laws
or as a result of legislative or administrative action (whether state or federal) or by final decree, judgment or order of any
court or administrative body (whether state or federal) entered after any contest thereof by the Issuer or the Company in good
faith, this Agreement shall have become void or unenforceable or impossible of performance in accordance with the intent and purpose
of the parties as expressed in this Agreement.

 

(d)Unreasonable
burdens or excessive liabilities shall have been imposed upon the Issuer or the Company with respect to a Project or a Generating
Station or the operation thereof, including, without limitation, the imposition of federal, state or other ad valorem, property,
income or other taxes other than ad valorem

 

    	22

    	 

    

taxes at the rates
presently levied upon privately owned property used for the same general purpose as a Project or a Generating Station.

 

(e)Changes
in the economic availability of raw materials, operating supplies, energy sources or supplies or facilities (including, but not
limited to, facilities in connection with the disposal of industrial wastes) necessary for the operation of a Project or a Generating
Station for the Project Purposes occur or technological or other changes occur which the Company cannot reasonably overcome or
control and which in the Company’s reasonable judgment render a Project or a Generating Station uneconomic or obsolete for
the Project Purposes.

 

(f)Any court
or administrative body shall enter a judgment, order or decree, or shall take administrative action, requiring the Company to cease
all or any substantial part of its operations served by a Project or a Generating Station to such extent that the Company is or
will be prevented from carrying on its normal operations at a Project or a Generating Station for a period of six consecutive months.

 

(g)The termination
by the Company of operations at a Generating Station.

 

As used in this Section
6.2, the term “a Project” means the portion of the Project Facilities at a particular Generating Station.

 

The amount payable by
the Company in the event of its exercise of the option granted in this Section shall be the sum of the following:

 

(i)An amount
of money which, when added to the moneys and investments held to the credit of the Bond Fund, will be sufficient pursuant to the
provisions of the Indenture to pay, at a redemption price of 100% of the principal amount redeemed plus accrued and unpaid interest
to the redemption date, and discharge, the Outstanding Bonds then being redeemed on the earliest applicable redemption date, that
amount to be paid to the Trustee, plus

 

(ii)An amount
of money equal to the Additional Payments relating to those Bonds accrued and to accrue until actual final payment and redemption
of those Bonds, that amount or applicable portions thereof to be paid to the Trustee or to the Persons to whom those Additional
Payments are or will be due.

 

The requirement of (ii) above with respect
to Additional Payments to accrue may be met if provisions satisfactory to the Trustee and the Issuer are made for paying those
amounts as they accrue.

 

The rights and options
granted to the Company in this Section may be exercised whether or not the Company is in default hereunder; provided, that such
default will not relieve the Company from performing those actions which are necessary to exercise any such right or option granted
hereunder.

Article VI, the Company shall, within 180 days following the event authorizing the exercise of such option, or at any time during
the continuation of the condition referred to in paragraphs (c), (d) or (e) of Section 6.2 hereof, or at any time that optional
redemption of the Bonds is permitted under the Indenture as provided in Section 6.1 hereof, or promptly upon the occurrence of
a Determination of Taxability, give written notice to the Issuer, the Trustee and the Company Mortgage Trustee that it is exercising
its option to direct the redemption of Bonds, or that the redemption thereof is required by Section 4.01(b) of the Indenture due
to the occurrence of a Determination of Taxability, as the case may be, in accordance with the Agreement and the Indenture, and
shall specify therein the date on which such redemption is to be made, which date shall not be more than 180 days from the date
such notice is mailed. The Company shall make arrangements satisfactory to the Trustee for the giving of the required notice of
redemption to the Holders of the Bonds, in which arrangements the Issuer shall cooperate. The Company shall make arrangements

take all steps required of it under the applicable provisions of the Indenture or the Bonds to effect the redemption of all or
a portion of the Bonds pursuant to this Article VI.

 

Section 6.6.Concurrent
Discharging of First Mortgage Bonds. In the event any of the Bonds or portion thereof shall be paid and discharged, or deemed
to be paid and discharged, pursuant to any provisions of this Agreement and the Indenture, so that such Bonds or such portion thereof

EVENTS OF DEFAULT AND REMEDIES

 

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

 

(a)The occurrence
of an event of default as defined in Section 7.01 (a), (b), (c), (d) or (g) of the Indenture;

 

(b)The Company
shall fail to observe and perform any other agreement, term or condition contained in this Agreement, other than such failure as
will have resulted in an event of default described in (a) above and the continuation of that failure for a period of 90 days after
notice thereof shall have been given to the Company by the Issuer or the Trustee, or for such longer period as the Issuer may agree
to in writing; provided, that such failure shall not constitute an Event of Default so long as the Company institutes curative
action within the applicable period and diligently pursues that action to completion within 150 days after the expiration of initial
cure period as determined above, or within such longer period as the Issuer may agree to in writing; and

 

(c)The occurrence
of a “completed default” as defined in Section 1 of Article Twelve of the Company Mortgage.

 

Notwithstanding the foregoing,
if, by reason of Force Majeure, the Company is unable to perform or observe any agreement, term or condition hereof which would
give rise to an Event of Default under subsection (b) hereof, the Company shall not be deemed in default during the continuance
of such inability. However, the Company shall promptly give written notice to the Trustee and the Issuer of the existence of an
event of Force Majeure and shall use its best efforts to remove the effects thereof; provided that the settlement of strikes or
other industrial disturbances shall be entirely within its discretion.

 

The exercise of remedies
hereunder shall 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
7.2.Remedies on Default. Whenever an Event of Default shall have happened and be subsisting, either or both of the
following remedial steps may be taken:

 

(a)The Issuer
or the Trustee may have access to, inspect, examine and make copies of the books, records, accounts and financial data of the Company,
only, however, insofar as they pertain to the Projects; or

 

(b)The Issuer
or the Trustee may pursue all remedies now or hereafter existing at law or in equity to recover all amounts, including all Loan
Payments and Additional Payments, then due and thereafter to become due under this Agreement (including Loan Payments due upon
tender for purchase or pursuant to acceleration), or to enforce the performance and observance of any other obligation or agreement
of the Company under this Agreement.

 

    	25

    	 

    

Notwithstanding the foregoing, the Issuer
shall not be obligated to take any step which in its 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 Issuer at no cost or expense to the Issuer.
Any amounts collected as Loan Payments or applicable to Loan Payments and any other amounts which would be applicable to payment
of Bond Service Charges collected pursuant to action taken under this Section 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 5.08 of the Indenture for transfers of remaining amounts in the Bond Fund.

 

The provisions of this
Section are subject to the further limitation that the rescission and annulment by the Trustee of its declaration that all of the
Bonds are immediately due and payable also shall constitute a rescission and annulment of any corresponding declaration made pursuant
to this Section and a rescission and annulment 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 rescission and annulment shall extend to or affect any subsequent
or other default or impair any right consequent thereon.

 

Section
7.3.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 such remedy shall be cumulative and shall be in
addition to every other remedy given under this Agreement, or 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 or 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
7.4.Agreement to Pay Attorneys' Fees and Expenses. If an Event of Default should occur and the Issuer or the Trustee
should incur expenses, including attorneys' fees and expenses, in connection with the enforcement of this Agreement or the collection
of sums due hereunder, the Company shall be required, to the extent permitted by law, to reimburse the Issuer and the Trustee,
as applicable, for the fees and expenses so incurred upon demand.

 

Section
7.5.No Waiver. No failure by the Issuer or the Trustee to insist upon the strict performance by the Company of any
provision hereof shall constitute a waiver of their right to strict 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
7.6.Notice of Default. The Company shall notify the Trustee immediately 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.
