cause such acquisition, construction, improvement, equipping, and furnishing to be completed as soon as reasonably commercially practicable, delays incident to strikes, riots, acts of God, or the public enemy, or other causes beyond the reasonable

 5 

 
there shall be no diminution in or postponement of the Loan Payments to be made by the Company hereunder, and no resulting liability on the part of the
Issuer. The Company agrees, however, to use its best efforts to remedy with all commercially reasonable dispatch the cause or causes preventing it from carrying out its agreements; provided, that the settlement of strikes, lockouts and other
industrial disturbances shall be entirely within the discretion of the Company, and the Company shall not be required to make settlement of strikes, lockouts and other industrial disturbances by acceding to the demands of the opposing party or
parties when such course is, in the judgment of the Company, unfavorable to the Company. 
 (b) The Company shall acquire, construct, and
improve the Project or cause the Project to be acquired, constructed, and improved in the manner provided in this Agreement and in accordance with the Plans and Specifications on file and available to the Issuer at each Facility during the
construction period (subject to the restrictions of subsection (c) below) and the Trustee shall have no responsibility or liability whatsoever with respect to the Project and the acquisition, construction, improvement, equipping or furnishing
thereof. The Company may amend, or cause to be amended, such Plans and Specifications, provided, however, that such Plans and Specifications shall not be amended in any material respect except as provided in subsection (d) below. It is agreed
and understood that the Company will cause to be entered into and executed all agreements and contracts necessary to assure and accomplish the actual acquisition, construction, improving, equipping, and furnishing of the Project (and that the Issuer
shall not execute any such agreements or contracts) and that the Company will cause to be carried out, paid, supervised, and enforced all such agreements and contracts, and will cause to be provided such insurance on and in connection with the
acquisition, construction, improvement, equipping, and furnishing of the Project as it deems necessary or advisable or as is required by law and this Agreement in accordance with its customary insurance practices, which may include self insurance.
The Company shall pay or cause to be paid, from proceeds from the sale and delivery of the Bonds loaned to it pursuant to Section 4.02 of this Agreement, and from any available income or earnings derived therefrom, and if such proceeds or
income or earnings derived therefrom are insufficient, from other funds of the Company or available to the Company to the extent necessary, all Project Costs. The Issuer shall loan the proceeds from the sale of the Bonds to the Company to be used by
the Company to pay all or part of the Project Costs, in accordance with procedures established in Section 3.03 hereof for reimbursing the Company for paying all or any part of such Project Costs under the aforesaid agreements and contracts for
the acquisition, construction, improvement, equipping, and furnishing of the Project prior to the Company’s receipt of the Loan as hereinafter provided. It is specifically provided, however, that none of the proceeds from the sale of the Bonds
will be used to reimburse the Company for, or to pay (and the Company hereby covenants and agrees not to request reimbursement of or payment for) any part of the Project Costs if such use or payment would result in a violation of any of the
Company’s representations contained in Sections 2.02 or 7.06 hereof or the Tax Agreement. 
 (c) The Company hereby grants to the
Issuer, its employees and agents, at all reasonable times during normal business hours and upon reasonable notice such necessary and reasonable rights of ingress and egress to the Project as are available to the Company and required in connection
with the acquisition, construction, and improvement of the Project and the Company agrees that it will cooperate with the Issuer, its employees and agents, so that such Project shall be acquired, constructed, and improved as provided in this
Agreement. The Issuer, its employees and agents shall not unnecessarily disrupt or interfere with the operation of the 

  

 6 

 
Project and shall cooperate with and observe the reasonable regulations of the Company so as to avoid any unnecessary disruption or interference with said
operation. Unless the Company shall be in default hereunder or under the Indenture, the Company may require that the rights of access hereby reserved to the Issuer, its employees and agents, may be exercised only after such employees or agents have
executed release of liability agreements in the form then used by the Company. The Issuer recognizes that the drawings, designs, specifications, material lists, and other engineering documents and information contained in the Plans and
Specifications or otherwise provided or made available to the Issuer in connection with the Project are proprietary to, and are the property of the Company and/or its affiliates. The Issuer agrees to retain in confidence and not to disclose to
others (except as required by applicable law) or to use or permit the use for the benefit of or by others, without the prior written consent of the Company in each such instance, any such drawings, designs, specifications, material lists and other
engineering documents and information contained in the Plans and Specifications or otherwise provided or made available to the Issuer. Nothing in this Section or in any other provision of this Agreement shall be construed to entitle the Issuer or
the Trustee, to any information or inspection involving the confidential know how of the Company. 
 (d) If the Plans and Specifications are
materially amended at any time prior to the completion of the Project, the Company shall (i) deliver to the Issuer a certificate of an Authorized Company Representative stating that the Project constructed pursuant to the Plans and
Specifications, as amended, will be solid waste disposal facilities within the meaning of Section 142(a)(6) of the Code or any substantially similar successor provision, and (ii) furnish the Issuer and Trustee with a Favorable Opinion with
respect to such proposed amendment and the expenditure of moneys from the Construction Fund to pay the Project Costs as shown on the Plans and Specifications as so amended. Any material amendment to the Plans and Specifications for a Facility must
be accompanied by (i) a certificate from the Construction Consultant to the effect that such amendment does not impair the ability of the Facility to generate the quantity of Salable Renewable Natural Gas shown in the Base Case Output
Assumptions shown for such Facility in the Feasibility Study and (ii) a certificate of the Company demonstrating the pro forma effect of any change in projected revenues from the Facility as a result of such amendment. 
 (e) If, for any reason, the proceeds from the sale of the Bonds are not sufficient to pay all the Project Costs, the Company shall complete or cause to
be completed the Project and pay or cause to be paid all Project Costs which are not or cannot be paid or reimbursed from proceeds of the Bonds from its own funds or other funds available to the Company or its affiliates, but it shall not be
entitled to reimbursement from the Issuer therefor, or to any diminution in or postponement of any payments required to be made by the Company hereunder. 
 Section 3.03. Construction Fund; Costs of Issuance Fund. The Construction Fund shall be drawn on and used to pay Project Costs when due and payable. The Costs of Issuance Fund shall be drawn on and used to
pay Costs of Issuance when due and payable. The Issuer shall pay to the Trustee for deposit the proceeds from the sale and delivery of the Bonds pursuant to Section 3.1 of the Indenture or pursuant to any Supplemental Indenture. The Trustee,
pursuant to request of the Company, shall draw on and use the Construction Fund and Costs of Issuance Fund as follows: 
 (a) Immediately
after the delivery of each Series of Bonds authorized hereby, the Company, or the Trustee, upon written direction of the Authorized Company Representative, shall pay directly from the Costs of Issuance Fund (i) to the Issuer, the amount
specified in Section 5.04 hereof and (ii) to such other parties submitting invoices, the other Costs of Issuance relating to such Series of Bonds. 
  

 7 

 (b) Subject to the provisions of the Indenture, the Trustee shall make payments to the Company or, at the
Company’s written request, to a third party, from the Costs of Issuance Fund for any Costs of Issuance (in addition to those paid under Section 3.03(a) above) and, from the Construction Fund, subject to subsections (c), (f), and
(g) below, the Project Costs from time to time upon receipt by the Trustee of a request of the Company signed by the Authorized Company Representative. Such request shall be accompanied by a certificate signed by an Authorized Company
Representative (and, in the case of Project Costs, accompanied by the Certificate of the Construction Consultant approving such payment pursuant to the provisions of Section 3.03(f) hereof) stating with respect to each payment as follows:

 (i) the name of the Facility or Facilities to which the Project Costs apply; 
 (ii) the name of the subaccount in the Costs of Issuance Fund (in the case of payments for Costs of Issuance) relating to such Series of
Bonds; 
 (iii) the name and address of the person, firm or corporation to whom payment is to be made; 
 (iv) the amount of expenditures for which payment or reimbursement is requested; 
 (v) in the case of requisitions from the Construction Fund, the amount requested to be paid has been or will be incurred and is for
Project Costs; 
 (vi) no part of the several amounts requested to be paid, as stated in such certificate, has been or is the
basis for the payment of any money in any previous or then pending request; 
 (vii) the payment of the amount requested will
not result in a breach of the covenants of the Company contained in this Agreement; 
 (viii) the expenditure of such amount
to be disbursed, when added to all disbursements under previous requisitions, will result in at least 95% of the total of such disbursements being used to provide “solid waste disposal facilities” within the meaning of
Section 142(a)(6) of the Code or facilities functionally related and subordinate thereto; 
 (ix) in the case of
requisitions from the Costs of Issuance Fund, that the cumulative total amount disbursed thereunder for Costs of Issuance, together with any compensation to the Underwriter as a discount, does not exceed 2% of the proceeds of the Bonds; and

  

 8 

 (x) a bring down certificate from the issuer of the Title Policy or Title Policies
(defined herein) reflecting the absence of any mechanics liens for the subject Facility or Facilities. 
 (c) The Company is responsible for
determining the allocation of funds in the Construction Fund among portions of the Project and for monitoring expenditures based on such allocations. The Trustee shall rely fully on any such request and certificate delivered pursuant to this Section
and shall not be required to make any investigation in connection therewith. If amounts paid by the Trustee pursuant to subsection (b) above with respect to any portion of the Project exceed the cost thereof, the Company shall promptly repay
such overpayment into the Construction Fund or Costs of Issuance Fund, as applicable. 
 (d) The Issuer hereby gives its express written
authority to the Company, absent an Event of Default, to direct the investment of the Construction Fund by the Trustee as hereinafter provided and as permitted by the Indenture. Any money held as part of the Construction Fund shall be invested or
reinvested by the Trustee upon written direction of the Company in the same manner as provided for money on deposit in the Bond Fund. Upon acceleration of the maturity of the Bonds pursuant to the Indenture, subject to Section 6.4 of the
Indenture, any amounts held in or on deposit in the Construction Fund shall be transferred by the Trustee to the Bond Fund. 
 (e) If, upon
delivery of the Project Completion Certificate, there shall be any surplus funds remaining in the Construction Fund not required to provide for the payment of the costs of acquisition, construction, and improvement of the Project, such funds shall,
upon the written request of the Authorized Company Representative to the Trustee, be used by the Trustee (i) to purchase for cancellation Bonds at any reasonable price as determined by the Authorized Company Representative, which price,
however, shall not exceed the principal amount thereof plus accrued interest thereon or (ii) to redeem Bonds in the largest principal amount then subject to redemption at par (together with accrued interest thereon) that does not exceed the
amount of such funds. 
 (f) The Construction Consultant will review each request of the Company delivered pursuant to Section 3.03(b)
for payment of Project Costs. The Construction Consultant will provide a Certificate approving the payment of Project Costs upon receipt and satisfactory review of the request of the Company and certification by the Company accompanied by
appropriate documentation of: 
 (i) A statement that the Project Costs for the Facility to be paid with the funds requested
by such request of the Company represent work that has been satisfactorily performed in a good and workmanlike manner and in conformance with such Facility’s plans and specifications that were presented to the Construction Consultant as part of
its initial review of such Facility. 
 (ii) An estimate of the remaining Project Costs to complete the Facility, segregated
by major categories and Facility, and that sufficient funds remain to obtain Facility completion. 
  

 9 

 (iii) A statement that there is no material change in the Budgeted Cost or a detailed
description of the cost variances from the Budgeted Cost of each Facility, as of the date of the request of the Company. 
 (iv) A statement that no Event of Default under this Agreement or the Indenture has occurred and is continuing. 
 (v) A monthly progress report prepared for the month to which the request relates, including but not limited to status of engineering, procurement, construction, start-up, and performance testing; schedule; percentage of completion and
variances thereof; change orders; and action items. 
 (g) Notwithstanding anything to the contrary in this Section, no drawing from the
Construction Fund may be made for any Project Costs of a Facility until the Company has filed with the Trustee a certificate stating that: 
 (i) the Company or the subsidiary that is developing the Facility continues to have a valid lease estate in the Facility site sufficient for construction and operation of the Facility supported by a title report
showing no mechanic’s liens on the site and shall have supplied the Collateral Trustee with an appropriately filed deed of trust on such leasehold estate naming the Collateral Trustee as beneficiary thereon and title insurance (each, a
“Title Policy”) evidencing a first priority lien in favor of the Collateral Trustee pursuant to such deed of trust, all as satisfactory to the Majority Holders;

Certificate. 
 (a) Anything in this Agreement to the contrary notwithstanding, the Company shall have the right at any time to terminate
the construction of a Facility if: (i) the Company shall have determined that the construction or operation of such Facility is impracticable, uneconomical or undesirable due to (A) the imposition of taxes, other than ad valorem taxes
currently levied upon privately owned property used for the same general purpose as such Facility, or other liabilities or burdens with respect to such Facility or the construction or operation thereof, (B) changes in technology, in

 (d) At the time of completion of the Project, the Company shall prepare a certificate showing the final Project Costs (the “Final Costs”), together with supporting material satisfactory to the Trustee
demonstrating that the Company (or the relevant subsidiary) has invested as equity at least 20% of the Final Costs. If the Company’s (or the relevant subsidiary’s) equity contribution to the Project Costs is greater than 20% of the Final
Costs 

  

 11 

 
relating to such Facility, the Company (or the relevant subsidiary) may requisition funds from the related subaccount within the Construction Fund, if any

 Section 3.05. Abandonment. If
the Company determines to abandon construction of the Project before drawing on the Construction Fund, it shall deliver to the Trustee an Abandonment Certificate and shall direct the Trustee to transfer the amounts remaining in the funds and
accounts established in the Indenture, except the Rebate Fund, to the Bond Fund to purchase for cancellation or redeem Bonds pursuant to Section 9.1(c)(ii) of the Indenture.

that the Issuer shall have no duties or responsibilities whatsoever with respect to the operation or maintenance of the Project, or the performance of the Project for its designed purposes. After the Completion Date, the Company may at its own
expense cause the Project to be remodeled or cause substitutions, modifications and improvements to be made to the Project from time to time as it, in its discretion, may deem to be desirable for its uses and purposes, which remodeling,
substitutions, modifications and improvements shall be included under the terms of this Agreement as part of the Project. 
 Section 3.09. [Reserved]. 
 Section 3.10. Insurance and Condemnation Awards. The net proceeds of any
insurance or condemnation award as a result of the destruction or condemnation of the Project or any portion thereof shall, at the option of the Company, either (a) be paid by the Company to the Trustee for deposit into the Bond Fund under the

 ARTICLE V 
 THE COMPANY’S PAYMENTS 
 Section 5.01. Company Approval of Issuance of Bonds. 
 (a) In consideration of the covenants and agreements set forth in this Agreement, and to enable the Issuer to issue the Bonds to carry out the intents and purposes hereof, this Agreement is executed to assure the
issuance of such Bonds, and to provide for the due and punctual payment by the Company to the Issuer, or to the Trustee under the Indenture securing the Bonds, of amounts required to pay, as and when due (whether at stated maturity, upon redemption,
acceleration of maturity, tender, deemed tender, or otherwise), and at such time as will assure payment on the due date thereof, all of the principal of, redemption premium, if any, and interest on, the Bonds. Each such payment is hereby designated
as a “Loan Payment”, and collectively such payments are hereby designated as “Loan Payments”. The Company hereby agrees to make, or cause to be made, each Loan Payment, as and when due, for the benefit of the owners of the Bonds
into the Bond Fund, as provided in the Indenture. 
 (b) By execution and delivery of this Agreement, the Company hereby approves the
Indenture. It is hereby agreed that the foregoing approval of the Indenture constitutes the acknowledgment and agreement of the Company that the Bonds, when issued, sold, and delivered as provided in the Indenture, will be issued in accordance with
and in compliance with this Agreement, notwithstanding any other provisions of this Agreement or any other contract or agreement to the contrary. Any Bondholder is entitled to rely fully and unconditionally on the foregoing approval. Notwithstanding
any provisions of this Agreement or any other contract or agreement to the contrary, the Company’s approval of the Indenture shall be the Company’s agreement that all covenants and provisions in this Agreement and the Indenture affecting
the Company shall, upon the delivery of the Bonds and the Indenture, become unconditional, valid, and binding covenants and obligations of the Company so long as the Bonds and the interest thereon are outstanding and unpaid. Particularly, the
obligation of the Company to make, promptly when due, all Loan Payments specified in this Agreement and the Indenture shall be absolute and unconditional, and said obligation may be enforced as provided in this Agreement and the Indenture.

 Section 5.02. Payment Upon Redemption of Bonds. The Issuer, upon the written request of the Company (and provided that the
affected Bonds are subject to redemption or prepayment prior to maturity at the option of the Issuer, or the Company, and provided that such request is received in sufficient time prior to the date upon which such redemption or prepayment is
proposed), forthwith shall take or cause to be taken all action that may be necessary under the applicable redemption provisions of the Indenture to effect such redemption 

  

 15 

 
prior to maturity, to the full extent of funds either made available for such purpose by the Company or already on deposit under the Indenture and available
for such purpose. The redemption of any outstanding Bonds prior to maturity at any time shall not relieve the Company of its absolute and unconditional obligation to pay each remaining Loan Payment with respect to any outstanding Bonds, as specified
in the Indenture. If a redemption of Bonds is required pursuant to the provisions of the Indenture, the Company agrees as provided herein to forthwith make Loan Payments sufficient to pay the principal of, redemption premium, if any, and interest on
the Bonds. 
 Section 5.03. Loan Payments. On or before the twenty-fifth (25th) day of each month, until the principal of,
premium, if any, and interest on, the Bonds shall have been fully paid or provision for such payment shall have been made as provided in the Indenture, the Borrower covenants and agrees to pay to the Trustee as a repayment on the loan made to the
Borrower from Bond proceeds pursuant to Section 4.02 hereof, (a) a sum equal to one-sixth of the aggregate amount of interest becoming due and payable on the next Bond Payment Date on all Bonds then Outstanding, less any amounts to be
transferred to the Bond Fund from the Capitalized Interest Account for the payment of such interest, and (b) one twelfth of the principal becoming due and payable on the Outstanding Bonds plus one-twelfth of the aggregate amount of mandatory
redemption payments required to be paid on the next Bond Payment Date, provided that until the first principal payment date with respect to the Bonds (if less than twelve months), transfers into the Bond Fund shall be sufficient on a monthly pro
rata basis to pay the principal becoming due and payable on such Bond Payment Date. Such Loan Payments shall be made in federal funds or other funds immediately available at the Corporate Trust Office of the Trustee. The term “Bond Payment
Date” as used in this Section shall mean any date upon which any amounts payable with respect to the Bonds shall become due, whether upon redemption (including without limitation mandatory redemption), acceleration, maturity or otherwise.

 The payments made pursuant to this Section 5.03 shall in the aggregate be sufficient to pay the total amount of interest and
principal (whether at maturity or upon redemption or acceleration) and premium, if any, becoming due and payable on the Bonds on each principal or interest payment date; provided that once per year, on the third Business Day following the Bond
Payment Date of each December, any amount held by the Trustee in the Bond Fund on the due date for a Loan Payment hereunder shall be credited against the installment due on the next Bond Payment Date to the extent available for such purpose under
the terms of the Indenture; and provided further that, subject to the provisions of this paragraph, if at any time the amounts held by the Trustee in the Bond Fund are sufficient to pay all of the principal of and interest and premium, if any, on,
the Bonds as such payments become due, the Borrower shall be relieved of any obligation to make any further payments under the provisions of this Section. Notwithstanding the foregoing, if three (3) days prior to any Bond Payment Date the
amount held by the Trustee in the Bond Fund is insufficient to make any required payments of principal of (whether at maturity or upon redemption (including without limitation mandatory redemption) or acceleration) and interest and premium, if any,
on, the Bonds as such payments become due, the Borrower shall forthwith pay such deficiency as a Loan Payment hereunder. 
 Section 5.04. Additional Payments. In addition to the Loan Payments, the Company shall also pay to the Issuer or to the Trustee, as the case may be, “Additional Payments,” as follows: 
 (a) All taxes and assessments of any type or character charged to the Issuer affecting the amount available to the Issuer from payments to be received
hereunder or in any way arising due to the transactions contemplated hereby (including taxes and assessments assessed or levied by any public agency or governmental authority of whatsoever character having power to levy taxes or assessments) but
excluding franchise taxes based upon the capital and/or income of the Trustee and taxes based upon or measured by the net income of the Trustee; provided, however, that the Company shall have the right to protest any such taxes or assessments and to
require the Issuer, at the Company’s expense, to protest and contest any such taxes or assessments levied upon them and that the Company shall have the right to withhold payment of any such taxes or assessments pending disposition of any such
protest or contest unless such withholding, protest or contest would adversely affect the rights or interests of the Issuer; 
  

 16 

 (b) All reasonable fees, charges and expenses of the Trustee for services rendered under the Indenture
and all amounts referred to in the Indenture, as and when the same become due and payable; 
 (c) The reasonable fees and expenses of such
accountants, consultants, attorneys and other experts as may be engaged by the Issuer or the Trustee to prepare audits, financial statements, reports, opinions or provide such other services required under this Agreement, the Tax Agreement or the
Indenture; 
 (d) The annual fee of the Issuer and the reasonable fees and expenses of the Issuer or any agent or attorney selected by the
Issuer to act on its behalf in connection with this Agreement, the Tax Agreement, the Bonds or the Indenture, including, without limitation, any and all reasonable expenses incurred in connection with the authorization, issuance, sale and delivery
of any such Bonds or in connection with any litigation, investigation, inquiry or other proceeding which may at any time be instituted involving this Agreement, the Tax Agreement, the Bonds or the Indenture or any of the other documents contemplated
thereby, or in connection with the reasonable supervision or inspection of the Company, its properties, assets or operations or otherwise in connection with the administration of this Agreement the Tax Agreement; and 
 (e) Such Additional Payments shall be billed to the Company by the Issuer or the Trustee from time to time, together with a statement certifying that the
amount billed has been incurred or paid by the Issuer or the Trustee for one or more of the above items. 
 After such a demand, amounts so billed shall be
paid by the Company within 30 days after receipt of the bill by the Company. Notwithstanding the foregoing, the Issuer shall not be required to submit a bill to the Company for payment of the Issuer’s annual fee of 0.03% of the aggregate
principal amount of Bonds Outstanding under the Indenture. Such annual fee shall be paid by the Company to the Trustee on a prorata basis (i.e., the annual fee shall be divided by the number of payments to be made during each annual period based on
the number of interest payments), due and payable in arrears, on each respective Interest Payment Date (deeming, for purposes of calculating the prorata fee to be paid, any principal to be paid on or as of such Interest Payment Date as no longer
Outstanding) and shall be made as an Additional Payment in accordance with this Section and the Indenture. 
  

 17 

 Section 5.05. Payments to Replenish Debt Service Reserve Fund. In the event of a deficiency
in the Debt Service Reserve Fund, the Company shall, by the first Business Day of each of the next three calendar months following such deficiency, pay into the Debt Service Reserve Fund an amount equal to one-third of such deficiency. 

Section 5.06. Issuer’s Rights Assigned to Trustee. The Company is advised and recognizes that as security for the payment of the
Bonds, the Issuer will assign to the Trustee the Issuer’s rights under this Agreement, including the right to receive payments hereunder (except the right to receive payments, if any, under Section 5.04, 6.03, and 7.03(a) hereof) and
except the right to receive notices hereunder, and hereby directs the Company to make said payments directly to the Trustee. The Company herewith assents to such assignment and will make such payments directly to the Trustee without defense or
set-off by reason of any dispute between the Company and the Issuer or the Trustee. All rights against the Company arising under this Agreement or the Indenture and assigned to the Trustee under the Indenture may be enforced by the Trustee, or the
owners of the Bonds, to the extent provided in the Indenture, and the Trustee, or the owners of the Bonds, shall be entitled to bring any suit, action, or proceeding against the Company, to the extent provided in the Indenture, for the enforcement
of this Agreement, and it shall not be necessary in any such suit, action, or proceeding to make the Issuer a party thereto. 
 Section 5.07. Payments to Trustee. The Company agrees to pay (i) the initial acceptance fee of the Trustee and reasonable costs and expenses, including reasonable attorneys fees and expenses, incurred by the Trustee in
entering into and executing the Indenture and (ii) until the principal of, redemption premium, if any, and interest on the Bonds shall have been fully paid or provision for the payment thereof shall have been made in accordance with the
provisions of the Indenture, (A) an amount equal to the annual fee of the Trustee for the ordinary services of the Trustee, as trustee, rendered and its reasonable ordinary expenses incurred under the Indenture, including reasonable attorneys
fees and expenses, as and when the same become due, (B) the fees, charges and expenses of the Trustee, as Bond Registrar and as Paying Agent, and any other Bond Registrar or Paying Agent on the Bonds, as and when the same become due,

obligation of the Company until the amount in default shall have been fully paid. The provisions of this Section 5.07 shall survive termination of this Agreement. 
 Section 5.08. Usury. Anything herein to the contrary notwithstanding, it is the intention of the parties hereto to conform strictly to the usury laws in force that are applicable to this transaction.
Accordingly, all agreements among the parties hereto and beneficiaries hereof and their assigns or any of them, whether now existing or hereafter arising, and whether written or oral, are hereby limited so that in no contingency, whether by reason
of acceleration of amounts due hereunder or any part thereof or otherwise, shall the interest (including all sums that are deemed to be interest) contracted for, charged or received hereunder and/or with respect to the purchase of the Project exceed
the maximum amount permissible under applicable law.

 ARTICLE VI 
 DEFAULTS AND REMEDIES 
 Section 6.01. Events of Default. The occurrence and continuation of any
one of the following shall constitute an “Event of Default” under this Agreement (an “Event of Default”): 
 (a) failure
by the Company to pay, when due, Loan Payments with respect to principal of, redemption premium, if any, or interest on any Bond or failure to make any payments required by Section 5.05 hereof with respect to any deficiency in the Debt Service
Reserve Fund; or 
 (b) failure by the Company to observe and perform any covenant, condition or agreement on its part required to be
observed or performed in this Agreement, other than as referred to in (a) above, for a period of 90 days after receipt by the Company of written notice specifying such failure and requesting that it be remedied, 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 further, however, if the failure stated in the notice cannot be corrected within the applicable period,
the Issuer and the Trustee will not unreasonably withhold their consent to an extension of such time if corrective action is instituted within the applicable period and diligently pursued until the default is corrected; provided further, if any such
failure obligates the Company to prepay Loan Payments because of mandatory redemption of Bonds pursuant to Section 9.1(c) of the Indenture, and such prepayment is in fact made by the Company and Bonds are redeemed as provided in the Indenture,
then such failure by the Company shall not constitute an Event of Default under this Agreement; or 
 (c) the occurrence of an Act of
Bankruptcy and, if occurring by reason of clause (b) of the definition thereof, such petition resulting therefrom shall not be stayed or denied, or a proceeding resulting therefrom shall not be discharged, within 90 days after the filing of
such petition or the commencement of such proceeding, as the case may be; or 
 (d) the occurrence of an “Event of Default” under
the Indenture. 
 Section 6.02. Remedies on Default. Whenever any Event of Default shall have happened and is existing, the
Issuer, with the consent of the Trustee, or the Trustee may take any one or more of the following remedial steps, but only if acceleration of the principal amount of the Bonds has been declared pursuant to Section 11.2 of the Indenture:

 (a) By notice in writing to the Company, declare the unpaid Loan Payments to be due and payable immediately, if concurrently with or prior
to such notice the unpaid principal amount of the Bonds has been declared to be due and payable under the Indenture, and upon any such declaration the amounts payable under Sections 5.01 and 5.03 hereof shall become and shall be immediately due and
payable in the amount set forth in Section 11.2 of the Indenture; provided, however, that an Event of Default shall be deemed waived and a declaration accelerating payment of unpaid Loan Payments payable under this Agreement shall be deemed

  

 19 

 
rescinded without further action on the part of the Trustee or the Issuer upon any annulment by the Trustee of the corresponding declaration of acceleration
of the Bonds under Section 11.2 of the Indenture. 
 (b) Whatever action at law or in equity may appear necessary or desirable to
collect the payment and other amounts then due or to enforce performance and observance of any obligation, agreement or covenant of the Company under this Agreement. 
 In case the Issuer, with the consent of the Trustee, or the Trustee shall have proceeded to enforce its rights under this Agreement and such proceedings shall have been discontinued or abandoned for any reason or
shall have been determined adversely to the Issuer and/or the Trustee, then and in every such case the Issuer, the Company and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and
powers of the Issuer, the Company and the Trustee shall continue as though no such proceeding had been taken. 
 The Company covenants that,
in case an Event of Default shall occur with respect to the payment of any Loan Payment payable under Sections 5.01 and 5.03 hereof, then, upon written demand of the Trustee, the Company will pay to the Trustee the whole amount that then shall have
become due and payable under said Sections 5.01 and 5.03. 
 In case the Company shall fail forthwith to pay such amounts upon such demand,
the Trustee shall be entitled and empowered to institute any action or proceeding at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any
such judgment or final decree against the Company and collect in the manner provided by law out of the property of the Company, the moneys adjudged or decreed to be payable. Any sums collected by the Trustee shall be applied as provided in the
Indenture. The Issuer or the Trustee may pursue all remedies now or hereafter existing at law or in equity to enforce the performance and observance of any other obligation or agreement of the Company under this Agreement including, without
limitation, exercise the remedies of mandamus or the appointment of a receiver in equity with the power to charge and collect rents, purchase price payments, and loan payments and to apply revenues from the Project in accordance with the terms
hereof and of the Indenture. 
 If an Event of Default under Section 6.01(c) hereof shall occur and be continuing, the Trustee shall be
entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount owing and unpaid pursuant to this Agreement, irrespective of whether the principal of the Bonds or any amount
hereunder shall then be due and payable as therein or herein expressed or by declaration or otherwise, and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.02, and, in case of any
judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee allowed in such judicial proceedings relative to the Company, its creditors, or its
property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to distribute the same after the deduction of its fees, charges and expenses; and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized to make such payments to the Trustee, and to pay to the Trustee any amount due it for compensation and expenses, including reasonable counsel fees and expenses incurred by it up to the date of such distribution.

the Trustee shall be entitled to all of the rights, protections and immunities accorded to the Trustee under the terms of the Indenture, including but not limited to those set out in Article XII thereof. 
 Section 6.03. Agreement to Pay Attorneys’ Fees and Expenses. In the event the Company should default under any of the provisions of this
Agreement and the Issuer or the Trustee should employ attorneys or incur other expenses for the collection of the payments due under this Agreement or the enforcement of performance or observance of any obligation or agreement on the part of the
Company herein contained, the Company agrees that it will on demand therefor, and upon presentation of an itemized bill, pay to the Issuer or the Trustee the reasonable fees and expenses of such attorneys and such other expenses so incurred by the
Issuer or the Trustee, including such fees and expenses of in-house counsel and legal staff of the Trustee. 
 ARTICLE VII 
 SPECIAL COVENANTS 
 Section 7.01. No
Defense or Set-Off; Unconditional Obligation. The obligations of the Company to make the payments required by this Agreement and to perform and observe the other agreements on its part contained herein shall be absolute and unconditional,
irrespective of any defense or any rights of set-off, recoupment or counterclaim it might otherwise have against the Issuer or any other person, and the Company shall pay during the term of this Agreement the payments to be made as prescribed in
Article V and all other payments required hereunder free of any deductions and without abatement, diminution or set-off; and until such time as the principal of, redemption premium, if any, and interest on the Bonds shall have been fully paid, or
provision for the payment thereof shall have been made in accordance with the Indenture, the Company: (i) will not suspend or discontinue any payments provided for in Article V hereof; (ii) will perform and observe all of its other
agreements contained in this Agreement; and (iii) except as permitted herein, will not terminate this Agreement for any cause, including, without limiting the generality of the foregoing, failure of the Project to be acquired, constructed,
improved, or completed, failure of the Company to approve, receive, accept or use the Project, destruction of or damage to the Project, commercial frustration of purpose, any change in the tax laws of the United States of America or of the State of
California or any political subdivision of either of these, or any failure of the Issuer or the Trustee to perform and observe any agreement, whether express or implied, or any duty, liability or obligation arising out of or connected with this
Agreement or the Indenture, except to the extent permitted by this Agreement. Nothing contained in this Section shall be construed to relieve the Issuer or the Trustee from the performance of any agreements on their respective parts contained herein
and the Company shall be entitled to institute such action against the Issuer or the Trustee as the Company shall deem appropriate to compel performance of any such agreement, duty or obligation; provided, 

  

 21 

 
however, neither the Issuer nor the Trustee shall be required to carry out any such agreement, duty or obligation unless it is reimbursed for its costs and
expenses to the extent set forth in this Agreement. 
 Section 7.02. Consolidation and Merger. The Company covenants that during
the term hereof it will maintain its existence, will not transfer all or substantially all of its assets to, and will not consolidate with or merge into, another entity; provided that, subject to the provisions of the Guarantee and the Collateral
Trust Agreement and with the consent of the Majority Holders, the Company may consolidate with or merge into another domestic entity (i.e., a entity existing under the laws of one of the states of the United States or the District of Columbia), or
transfer to another domestic entity all or substantially all of its assets; provided that the surviving, resulting or transferee corporation, as the case may be, if it is other than the Company, (i) is a domestic entity as aforesaid and
qualified to do business in the State, and (ii) assumes in writing all of the obligations of the Company under this Agreement. The Company shall within fifteen days after the execution thereof, furnish to the Issuer and the Trustee appropriate
documentation demonstrating that the surviving, resulting or transferee corporation, as the case may be, is a domestic entity, is qualified to do business in the State, and has assumed in writing all of the obligations of the Company under this
Agreement. 
 Section 7.03. Indemnities. 
 (a) To the fullest extent permitted by law, the Company agrees to indemnify, hold harmless and defend the Issuer, the Program Participants, the Trustee, and each of their respective officers, governing members,
directors, officials, employees, attorneys and agents (collectively, the “Indemnified Parties”), against any and all losses, damages, claims, actions, liabilities, costs and expenses of any conceivable nature, kind or character (including,
without limitation, reasonable attorneys’ fees, litigation and court costs, amounts paid in settlement and amounts paid to discharge judgments) to which the Indemnified Parties, or any of them, may become subject under or any statutory law
(including federal or state securities laws) or at common law or otherwise, arising out of or based upon or in any way relating to: 
 (i) the Bonds, the Indenture, the Agreement, or the Tax Agreement or the execution or amendment hereof or thereof or in connection with transactions contemplated hereby or thereby, including the issuance, sale or resale of the Bonds;

 (ii) any act or omission of the Company or any of its agents, contractors, servants, employees, tenants or licensees in
connection with the Project or the Facilities, the operation of the Project or the Facilities, or the condition, environmental or otherwise, occupancy, use, possession, conduct or management of work done in or about, or from the planning, design,
acquisition, installation or construction of, the Project or the Facilities or any part thereof; 
 (iii) any lien or charge
upon payments by the Company to the Issuer and the Trustee hereunder in favor of any party other than the Issuer or the Trustee, or any taxes (including, without limitation, all ad valorem taxes and sales taxes), assessments, impositions and other
charges imposed on the Issuer or the Trustee in respect of any portion of the Project or the Facilities; 
  

 22 

 (iv) any violation of any Environmental Regulations with respect to, or the release of
any Hazardous Substances from, the Project or the Facilities or any part thereof; 
 (v) the defeasance and/or redemption, in
whole or in part, of the Bonds; 
 (vi) any untrue statement or misleading statement or alleged untrue statement or alleged
misleading statement of a material fact contained in any offering or disclosure document or disclosure or continuing disclosure document for the Bonds or any of the documents relating to the Bonds, or any omission or alleged omission from any
offering or disclosure document or disclosure or continuing disclosure document for the Bonds of any material fact necessary to be stated therein in order to make the statements made therein, in the light of the circumstances under which they were
made, not misleading; 
 (vii) any declaration of taxability of interest on the Bonds, or allegations that interest on the
Bonds is taxable or any regulatory audit or inquiry regarding whether interest on the Bonds is taxable; 
 (viii) the
Trustee’s acceptance or administration of the trust of the Indenture, or the exercise or performance of any of its powers or duties thereunder or under any of the documents relating to the Bonds to which it is a party; 
 except (A) in the case of the foregoing indemnification of the Trustee or any of its respective officers, members, directors, officials, employees, attorneys and
agents, to the extent such damages are caused by the negligence or willful misconduct of such Indemnified Party; or (B) in the case of the foregoing indemnification of the Issuer or the Program Participants or any of their officers, members,
directors, officials, employees, attorneys and agents, to the extent such damages are caused by the willful misconduct of such Indemnified Party. In the event that any action or proceeding is brought against any Indemnified Party with respect to
which indemnity may be sought hereunder, the Company, upon written notice from the Indemnified Party, shall assume the investigation and defense thereof, including the employment of counsel reasonably acceptable to the Indemnified Party, and shall
assume the payment of all expenses related thereto, with full power to litigate, compromise or settle the same in its sole discretion; provided that the Indemnified Party shall have the right to review and approve or disapprove any such compromise
or settlement. Each Indemnified Party shall have the right to employ separate counsel in any such action or proceeding and participate in the investigation and defense thereof, and the Company shall pay the reasonable fees and expenses of such
separate counsel; provided, however, that such Indemnified Party may only employ separate counsel at the expense of the Company if in the judgment of such Indemnified Party a conflict of interest exists by reason of common representation or if all
parties commonly represented do not agree as to the action (or inaction) of counsel. 
 (b) The Company hereby agrees to indemnify and hold
the Trustee and its directors, officers, agents, and employees (collectively, the “Indemnitees”) harmless from and against any and all claims, liabilities, losses, damages, fines, penalties, and expenses, including 

  

 23 

 
out of pocket, incidental expenses, legal fees and expenses, and the allocated costs and expenses of in-house counsel and legal staff (“Losses”)
that may be imposed on, incurred by, or asserted against, the Indemnitees or any of them in connection with or arising out of the Trustee’s performance under the Indenture, this Agreement or any other financing document. The Trustee shall not
be liable for any action taken or omitted by it in good faith unless a court of competent jurisdiction determines that the Trustee’s negligent or willful misconduct was the primary cause of any Losses. In addition to the immediately preceding
sentence, the Company also agrees to indemnify and hold the Indemnitees and each of them harmless from and against any and all Losses that may be imposed on, incurred by, or asserted against the Indemnitees or any of them for following any
instruction or other direction upon which the Trustee is authorized to rely pursuant to the terms of the Indenture, this Agreement, or any of the financing documents. 
 (c) The rights of any persons to indemnity hereunder and rights to payment of fees and reimbursement of expenses pursuant to this Agreement shall survive the final payment or defeasance of the Bonds and, in the case
of the Trustee, any resignation or removal of the Trustee for any reason. The provisions of this Section shall survive the termination of this Agreement. 
 Section 7.04. Expenses. The Company covenants and agrees to pay and indemnify the Issuer, the Program Participants and the Trustee against all reasonable fees, costs and charges, including reasonable fees
and expenses of attorneys, accountants, consultants and other experts incurred in good faith (and with respect to the Trustee, without negligence) and arising out of or in connection with this Agreement, the Tax Agreement, the Bonds or the
Indenture. These obligations and those in Section 7.03 shall remain valid and in effect notwithstanding repayment of the loan hereunder or the Bonds or termination of this Agreement or the Indenture. 
 Section 7.05. Non-Liability of the Issuer. The Issuer shall not be obligated to pay the principal of, redemption premium, if any, and
interest on the Bonds, except from Revenues as provided in the Indenture. Neither the faith and credit nor the taxing power of the State or any political subdivision thereof, nor the faith and credit of the Issuer or any member is pledged to the
payment of the principal or interest on the Bonds. The Issuer shall not be liable for any costs, expenses, losses, damages, claims or actions, of any conceivable kind on any conceivable theory, under or by reason of or in connection with this
Agreement, the Bonds or the Indenture, except only to the extent amounts are received for the payment thereof from the Company under this Agreement. 
 The Company hereby acknowledges that the Issuer’s sole source of moneys to repay the Bonds will be provided by the payments made by the Company pursuant to this Agreement, together with amounts held in certain
Funds and Accounts by the Trustee under the Indenture, and investment income thereon, and hereby agrees that if the payments to be made hereunder shall ever prove insufficient to pay all principal of, redemption premium, if any, and interest on the
Bonds as the same shall become due (whether by maturity, redemption, acceleration or otherwise), then upon notice from the Trustee, the Company shall pay such amounts as are required from time to time to prevent any deficiency or default in the
payment of such principal, redemption premium, if any, or interest, including, but not limited to, any deficiency caused by acts, omissions, nonfeasance or malfeasance on the part of the Trustee, the Company, the Issuer or any third party, subject
to any right of reimbursement from the Trustee, the Issuer or any such third party, as the case may be, therefor. 
  

 24 

 Section 7.06. Tax Covenant. The Company covenants and agrees that it will at all times do and
perform all acts and things permitted by law and this Agreement which are necessary or desirable in order to assure that interest paid on the Bonds (or any of them) will be excluded from gross income for federal income tax purposes and will take no
action that would result in such interest not being so excluded. Without limiting the generality of the foregoing, the Company agrees to comply with the provisions of the Tax Agreement. This covenant shall survive payment in full or defeasance of
the Bonds. 
 Section 7.07. Payment to Rebate Fund. The Company hereby covenants and agrees to make the determinations and to pay
any deficiency in the Rebate Fund, at the times and as described in Section 8.5 of the Indenture. In any event, if the amount of cash held in the Rebate Fund shall be insufficient to permit Trustee to make payment to the United States of any
amount due under Section 148(f)(2) of the Code, the Company forthwith shall pay the amount of such insufficiency on such date to Trustee in immediately available funds. The obligations of the Company under this Section 7.05 are direct
obligations of the Company, acting under the authorization of, and on behalf of, the Issuer and the Issuer shall have no further obligation or duty with respect to the Rebate Fund. 
 Section 7.08. Special Services Covenant. The Company shall maintain solid waste disposal facilities providing solid waste disposal services
to persons and businesses within the territorial limits of the Program Participants as long as any Bonds remain Outstanding; provided, however, the Issuer, upon review of such facts as it deems relevant, may, from time to time, allow the Company to
provide alternative services that provide public benefit to the Program Participants and their residents, or deem this special services covenant to be satisfied in whole or in part. Failure to comply with the provisions of this Section shall not
constitute an Event of Default under this Agreement, but shall be enforceable solely by the Issuer by such action, at law or in equity, as the Issuer in its sole discretion shall deem appropriate. This Section shall not be enforceable by the
Trustee, any Bondholder, the Program Participants, any resident of the Program Participants or by any other Person other than the Issuer. 
 ARTICLE VIII 
 GENERAL PROVISIONS 
 Section 8.01. General Provisions. 
 (a) The terms of this Agreement may be enforced as to one or
more breaches either separately or cumulatively. 
 (b) No remedy conferred upon or reserved to the Issuer, the Company or the Trustee in
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 now or hereafter existing at law or in equity or by statute. No
delay or omission to exercise any right or power accruing upon any default, omission, or failure of performance 

  

 25 

 
hereunder shall impair any such 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 the event any provision contained in this Agreement should be breached by the Issuer or the Company and thereafter duly waived, such waiver shall be limited to the particular breach so waived and shall not
be deemed to waive any other breach of this Agreement. No waiver by either party of any breach by the other party of any of the provisions of this Agreement shall be construed as a waiver of any subsequent breach, whether of the same or of a
different provision of this Agreement. In view of the assignment of the Issuer’s rights in and under this Agreement to the Trustee under the Indenture, the Issuer shall have no power to waive any default hereunder by the Company without the
consent of the Trustee. Any waiver of any “Event of Default” under the Indenture and a rescission and annulment of its consequences shall constitute a waiver of the corresponding Event of Default hereunder and a rescission and annulment of
the consequences thereof. 
 (c) Headings of the Sections of this Agreement have been inserted for convenience of reference only and in no
way shall they affect the interpretation of any of the provisions of this Agreement. 
 (d) This Agreement is made for the exclusive benefit
of the Issuer, the Trustee, the owners of the Bonds and the Company, and their respective successors and assigns herein permitted, and not for any third party or parties; and nothing in this Agreement, expressed or implied, is intended to confer
upon any party or parties other than the Issuer, the Trustee, and the Company, and their respective successors and assigns herein permitted, any rights or remedies under or by reason of this Agreement. In particular, but not by way of limitation,
the Trustee shall be a third-party beneficiary for purposes of enforcing its rights and the Company’s obligations under Sections 5.07 and 7.03(b) and (c) of this Agreement as fully as if the Trustee had been a party in privity of contract
with the Company hereunder. 
 Section 8.02. Financial Statements. The Company shall furnish to the Trustee as soon as available
and in any event within 120 days after the end of its fiscal year (currently December 31) a balance sheet of the Company and its consolidated subsidiaries as of the end of such fiscal year and the related statements of income, cash flows, and
change in stockholder’s equity for such fiscal year, all prepared in accordance with GAAP and reported on by an Accountant whose report shall state that such financial statements present fairly the Company’s financial position as of the
end of such fiscal year and the results of operations and cash flows for such fiscal year. Notwithstanding the foregoing, if and when and so long as the Company shall file regular and periodic reports with the United States Securities and Exchange
Commission pursuant to Section 13 and 15 of the Securities Exchange Act of 1934, the delivery by the Company to the Trustee of copies of its reports on Forms 10-K and 10-Q promptly following filing thereof with the United States Securities and
Exchange Commission shall constitute full compliance with this Section 8.02. The Trustee is authorized to provide to any Bondholder, upon written request and payment of all costs by such Bondholder, copies of any of such financial statements
and reports but the Trustee shall have no other responsibility with respect thereto. 
 Section 8.03. Amendment of Agreement. No
amendment, change, addition to, or waiver of any of the provisions of this Agreement shall be binding upon the parties hereto unless in writing signed by the Authorized Company Representative and the Authorized Issuer 

  

 26 

 
Representative, and acknowledged in writing by the Trustee and the Bank, if any. Notwithstanding any of the foregoing, it is covenanted and agreed, for the
benefit of the holders of the Bonds, and the Trustee that the provisions of this Agreement shall not be amended, changed, added to, or waived in any way which would relieve, reduce or abrogate the obligations of the Company to make or pay, or cause
to be made or paid, when due, all Loan Payments with respect to any then outstanding Bonds which have been issued and delivered pursuant to this Agreement, in the manner and under the terms and conditions provided herein and in the Indenture, or
which would change or affect Article II, Sections 5.01, 5.02, 5.03, 5.05, 5.06, 5.07, 6.01, 7.01, 7.02, 7.04, 7.05, 8.03, or 8.04 hereof unless, in the judgment of the Trustee, which may be made in reliance upon an opinion of Counsel, such change or
amendment would not materially adversely affect the interests of the Bondholders. 
 Section 8.04. Assignment. The Company may
assign its interest in this Agreement in whole or in part, provided, however, no assignment (other than pursuant to Section 7.02 hereof) shall relieve the Company from primary liability for any of its obligations hereunder, and without limiting
the generality of the foregoing, in the event of any such assignment, the Company shall continue to remain primarily liable for its payments specified herein and for performance and observance of the other covenants and agreements on its part herein
provided; and further provided that no assignment shall be effective unless there is delivered a Favorable Opinion with respect to such assignment. The Company shall, on or prior to the effective date of any such assignment, furnish or cause to be
furnished to the Issuer and the Trustee notice of such assignment, together with the referenced Favorable Opinion. 
 Section 8.05.
Term of Agreement. The term of this Agreement shall be from the date hereof until all payments and indemnities required to be made by the Company pursuant hereto shall have been made. 
 Section 8.06. Notices. Any notice, request or other communication under this Agreement shall be given in writing and shall be deemed to have

and Bond Registrar, in performing their respective duties hereunder, shall be entitled to the same protective provisions in the performance of their respective duties as are specified in Article XII of this Indenture with respect to the Trustee
hereunder to the same extent and as fully for all intents and purposes as though the Paying Agent and Bond Registrar had been expressly named therein in place of such Trustee and as though the applicable provisions of Article XII of this Indenture

be exchanged for other Bonds of any other authorized denomination, of a like aggregate principal amount and accruing interest at the same Interest Rate, upon surrender of the Bonds to be exchanged at the designated office of the Bond Registrar.
Whenever any Bonds are so surrendered for exchange, the Issuer shall execute, and the Trustee or the Authenticating Agent shall authenticate and deliver, the Bonds which the Bondholder making the exchange is entitled to receive. 
 All Bonds presented for registration of transfer or exchange shall be accompanied by a written instrument or instruments of transfer or authorization for
exchange, in form and with guaranty of signature satisfactory to the Bond Registrar, duly executed by the owner or by his attorney duly authorized in writing, and such documentation as the Bond Registrar shall reasonably require. 
 No service charge shall be made to a Bondholder for any exchange or registration of transfer of Bonds, but the Issuer or the Bond Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto. 
  

 22 

 New Bonds delivered upon any registration of transfer or exchange shall be valid obligations of the
Issuer, evidencing the same debt as the Bonds surrendered, shall be secured by this Indenture and shall be entitled to all of the security and benefits hereof to the same extent as the Bonds surrendered. 
 Except as provided above, the Trustee shall not be required to effect any transfer or exchange during the 15 days immediately preceding the date of
mailing of any notice of redemption or at any time following the mailing of any such notice in the case of Bonds selected for such redemption. 
 SECTION 2.5. Execution. All the Bonds shall, from time to time, be executed on behalf of the Issuer by the manual or facsimile signature of the President of the Issuer, its seal (which may be in facsimile) shall be thereunto affixed
(or printed or engraved or otherwise reproduced thereon if in facsimile), and attested by the manual or facsimile signature of the Secretary of the Issuer. 
 If any of the officers whose manual or facsimile signatures shall be upon the Bonds shall cease to be such officers of the Issuer before such Bonds shall have been actually authenticated by the Trustee or delivered by
the Issuer, such Bonds nevertheless may be authenticated, issued and delivered with the same force and effect as though the person or persons whose signature shall be upon such Bonds had not ceased to be such officer or officers of the Issuer; and
also any such Bonds may be signed and sealed on behalf of the Issuer by those persons who, at the actual date of the execution of such Bond, shall be the proper officers of the Issuer, although at the nominal date of such Bonds any such person shall
not have been such officer of the Issuer. 
 SECTION 2.6. Authentication; Authenticating Agent. No Bond shall be valid for any purpose
until either (i) the Certificate of Authentication substantially in the form set forth in Exhibit A attached hereto has been duly executed in accordance herewith by the Trustee or (ii) in the case of Bonds initially delivered to the
Underwriter, a Comptroller’s Registration Certificate attached to or endorsed on such Bond has been duly executed. Such executed Certificate of Authentication or Comptroller’s Registration Certificate, as the case may be, shall be
conclusive proof that such Bond has been duly authenticated and delivered under this Indenture and that the owner thereof is entitled to the benefit of the trust hereby created. 
 If the Bond Registrar is other than the Trustee, the Trustee may appoint the Bond Registrar as an Authenticating Agent with the power to act on the
Trustee’s behalf and subject to its direction in the authentication and delivery of Bonds in connection with the registration of transfers and exchanges under Section 2.4 hereof, and the authentication and delivery of Bonds by an
Authenticating Agent pursuant to this Section shall, for all purposes of this Indenture, be deemed to be the authentication and delivery “by the Trustee”. 
 Any corporation or association into which any Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation or association resulting from any merger, consolidation or
conversion to which any Authenticating Agent shall be a party, or any corporation or association succeeding to all or substantially all of the corporate trust business of any Authenticating Agent, shall be the successor of the Authenticating Agent
hereunder, if such successor corporation is otherwise eligible as a Bond Registrar under Section 2.3, without the execution or filing or any further act on the part of the parties hereto or the Authenticating Agent or such successor
corporation.

 Any Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee,
the Issuer and the Company. The Trustee may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent, the Issuer and the Company. Upon receiving such a notice of resignation or
upon such a termination, or in case at any time any Authenticating Agent shall cease to be eligible under this Section, the Trustee may, with the written consent of the Company (which shall not be unreasonably withheld) appoint a successor
Authenticating Agent, shall give written notice of such appointment to the Issuer, and shall mail notice of such appointment to all owners of Bonds as the names and addresses of such owners appear on the Bond Register. 
 Prior to delivery by the Trustee of the Bonds, there shall be filed with the Trustee:

as to interest as follows:

set forth in Section 2.2 hereof, with respect to the Series 2008A Bonds, or in a Supplemental Indenture, with respect to any Additional Bonds, initially from their respective Issue Dates, and thereafter (A) from the date of authentication,
if authenticated on an Interest Payment Date to which interest has been paid or duly provided for, or (B) from the last preceding Interest Payment Date to which interest has been paid in full or duly provided for (or the Issue Date if no
interest thereon has been paid or duly provided for) in all other cases. 
  

 24 

 (ii) Subject to the provisions of paragraph (c) below, the interest due on any Bond
on any Interest Payment Date shall be paid on each Interest Payment Date to the Registered Owner of such Bond as shown on the Bond Register as of the Regular Record Date. The amount of interest so payable on any Interest Payment Date shall be
computed on the basis of a 360-day year of twelve 30-day months. 
 (iii) All payments of interest on the Bonds shall be paid
by check to the Registered Owners entitled thereto. Any Registered Owner holding at least $1,000,000 par amount of the Bonds may receive payments of interest in immediately available funds by wire transfer to a bank within the continental United
States or deposited to a designated account if such account is maintained with the Paying Agent as directed by the Registered Owner in writing or as otherwise directed in writing by the Registered Owner at least five Business Days prior to each

but is not punctually paid or provided for, on any Interest Payment Date and within any applicable grace period (herein called “Defaulted Interest”) shall forthwith cease to be payable to the owner of such Bond on the relevant Regular

15 nor fewer than 10 days prior to the date of proposed payment. The Trustee shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first class postage prepaid, to each Bondholder at
his address as it appears in the Bond Register, not fewer than 10 days prior to such Special Record Date. 
 (d) Subject to the foregoing
provisions of this Section, each Bond delivered under this Indenture upon registration of transfer of or exchange for or in lieu of any other Bond shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other
Bond. 
 SECTION 2.8. Persons Deemed Owners. The Issuer, the Trustee, any Paying Agent, the Bond Registrar and any Authenticating
Agent may deem and treat the person in whose name any Bond is registered in the Bond Register as the absolute owner thereof (whether or not such Bond shall be overdue and notwithstanding any notation of ownership or other writing thereon made by
anyone other than the Issuer, the Trustee, any Paying Agent, the Bond Registrar or the Authenticating Agent) for the purpose of receiving payment of or on account of the principal of, redemption premium, if any, and (subject to Section 2.7)
interest on, such Bond, and for all other purposes, and neither the Issuer, the Trustee, any Paying Agent, the Bond Registrar, nor the 

  

 25 

 
Authenticating Agent shall be affected by any notice to the contrary. All such payments so made to any such Registered Owner, or upon his order, shall be
valid and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Bond. 
 SECTION 2.9. Mutilated, Destroyed, Lost or Stolen Bonds. 
 (a) If any Bond shall become mutilated, lost, stolen or destroyed,
the affected Bondholder shall be entitled to the issuance of a substitute Bond only as follows:

 Upon compliance with the foregoing, a substitute Bond of like tenor and denomination, executed by the Issuer, shall be authenticated by the Trustee or Authenticating
Agent and delivered to the Bondholder. 
 Notwithstanding the foregoing, the Trustee or Authenticating Agent shall not be required to
authenticate and deliver any substitute Bond for a Bond which has been called for redemption or which has matured or is about to mature and, in any such case, the principal, redemption price or Purchase Price and interest then due or becoming due
shall be paid by the Trustee or a Paying Agent in accordance with the terms of the mutilated, lost, stolen or destroyed Bond without substitution therefor. 
 (b) Every substituted Bond issued pursuant to this Section shall constitute an additional contractual obligation of the Issuer and shall be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Bonds duly issued hereunder. 
 (c) All Bonds shall be held and owned upon the express condition that the foregoing
provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Bonds, and shall preclude any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the replacement or payment of negotiable instruments or investment or other securities without their surrender. 
  

 26 

 SECTION 2.10. Temporary Bonds. Pending preparation of definitive Bonds, or by agreement with the
purchasers of all Bonds, the Issuer may issue, and, upon its request, the Trustee or Authenticating Agent shall authenticate, in lieu of definitive Bonds one or more temporary printed or typewritten Bonds of substantially the tenor recited above in
any Authorized Denomination. Upon written request of the Issuer, the Trustee shall authenticate definitive Bonds in exchange for and upon surrender of an equal principal amount of temporary Bonds. Until so exchanged, temporary Bonds shall have the
same rights, remedies and security hereunder as definitive Bonds. 
 SECTION 2.11. Cancellation of Surrendered Bonds. Bonds
surrendered for payment, redemption, transfer or exchange and Bonds surrendered to the Trustee by the Issuer or by the Company for cancellation shall be cancelled by the Trustee and such cancelled Bonds shall be delivered to the Company.

the Agreement. Neither the faith and credit nor the taxing power of the State or any political subdivision thereof (including the Program Participants), nor the faith and credit of the Issuer is pledged to the payment of the principal (or Redemption

 29 

 SECTION 2.15. Book Entry System. 
 (a) DTC will act as the initial Securities Depository for the Bonds. The Bonds shall be initially issued in the form of a single fully registered Bond
registered in the name of Cede & Co. (DTC’s nominee). So long as Cede & Co. is the Registered Owner of the Bonds, as nominee of DTC, references herein to Registered Owners, Bondholders or holders of the Bonds shall mean
Cede & Co. and shall not mean the beneficial owners of the Bonds. 
 (b) While DTC is the Securities Depository, the ownership
interest of each of the beneficial owners of the Bonds will be recorded through the records of a DTC Participant. Transfers of beneficial ownership interests in the Bonds which are registered in the name of Cede & Co. will be accompanied by
book entries made by DTC and, in turn, by the DTC Participants who act on behalf of the beneficial owners of the Bonds. 
 (c) With respect
to Bonds registered in the name of the Securities Depository, the Issuer, the Company, the Bond Registrar, the Paying Agent, and the Trustee shall have no responsibility or obligation to any person on behalf of whom such Securities Depository holds
an interest in the Bonds, except as provided in this Indenture. Without limiting the immediately preceding sentence, the Issuer, the Bond Registrar, the Paying Agent, and the Trustee shall have no responsibility or obligation with respect to
(i) the accuracy of the records of the Securities Depository with respect to any ownership interest in the Bonds, (ii) the delivery to any person, other than a Bondholder, as shown on the Bond Register, of any notice with respect to the
Bonds, including any notice of redemption, or (iii) the payment to any person, other than a Registered Owner, as shown in the Bond Register of any amount with respect to principal of, redemption premium, if any, or interest on, the Bonds.

 (d) Notwithstanding any other provisions of this Indenture to the contrary, the Issuer, the Bond Registrar, the Paying Agent, and the
Trustee shall be entitled to treat and consider the person in whose name each Bond is registered in the Bond Register as the absolute owner of such Bond for the purpose of payment of principal, redemption premium, if any, and interest with respect
to such Bond, for the purpose of giving notices of redemption and other matters with respect to such Bond, for the purpose of registering transfers with respect to such Bond, and for all other purposes whatsoever. The Paying Agent shall pay all
principal of, redemption premium, if any, and interest on the Bonds only to or upon the order of the respective owners, as shown in the Bond Register as provided in this Indenture, or their respective attorneys duly authorized in writing, and all
such payments shall be valid and effective to fully satisfy and discharge the Issuer’s obligations with respect to payment of principal of, redemption premium, if any, and interest on, the Bonds to the extent of the sum or sums so paid.

 (e) No person other than a Registered Owner, as shown in the registration books, shall receive a Bond certificate evidencing the
obligation of the Issuer to make payments of principal, redemption premium, if any, and interest, pursuant to this Indenture. 
 (f) Any
provision of this Indenture permitting or requiring the delivery of Bonds shall, while the book-entry system is in effect, be satisfied by the notation on the books of the Securities Depository, of the transfer of the beneficial owner’s
interest in such Bond. 
  

 30 

 (g) So long as the DTC book-entry system is in effect, the Trustee, the Paying Agent and the Bond
Registrar shall comply with the terms of the Letter of Representations. 
 (h) The Securities Depository may determine to discontinue
providing its service with respect to the Bonds at any time by giving reasonable notice and all relevant information on the beneficial owners of the Bonds to the Issuer or the Trustee. If there is no successor Securities Depository appointed by the
Issuer, the Trustee, upon presentation and surrender of Bonds then outstanding, shall authenticate and deliver Bonds to the beneficial owners thereof. In the event that the Company determines that the Securities Depository is incapable of
discharging its responsibilities described herein or in any agreement among the Issuer, the Trustee and the Securities Depository and that it is in the best interest of the beneficial owners of the Bonds that they be able to obtain certificated
Bonds, the Issuer, at the direction of the Company, shall (i) appoint a successor securities depository, qualified to act as such under Section 17(a) of the securities and Exchange Act of 1934, as amended, notify the Securities Depository
of the appointment of such successor securities depository and transfer one or more separate Bonds to such successor securities depository or (ii) notify the Securities Depository and owners, identified by the Securities Depository, of the
availability through the Securities Depository of Bonds and transfer one or more separate Bonds to owners, identified by the Securities Depository, having Bonds credited to their accounts. In each scenario described in this subsection (h), the
Securities Depository will provide the Trustee with the name, address of record, and taxpayer identification number of each beneficial owner of a Bond. In such event, the Bonds shall no longer be restricted to being registered in the Bond Register
in the name of the Securities Depository, but may be registered in the name of the successor securities depository, or its nominee, or in whatever name or names Bondholders transferring or exchanging Bonds shall designate, in accordance with the
provisions of this Indenture. 
 Upon the written consent of 100% of the beneficial owners of the Bonds, the Trustee, in accordance with any
agreement among the Issuer, the Trustee, and the Securities Depository, shall withdraw the Bonds from the Securities Depository, and authenticate and deliver Bonds fully registered to the assignees of the Securities Depository or its nominee. If the
request for such withdrawal is not the result of any Issuer action or inaction, such withdrawal, authentication and delivery shall be at the cost and expense (including costs of printing, preparing and delivering such Bonds) of the persons
requesting such withdrawal, authentication and delivery. 
 SECTION 2.16. Payments to Securities Depository; Payments to Beneficial
Owners. 
 (a) Notwithstanding any other provision of this Indenture to the contrary, so long as any Bond is registered in the name of
Cede & Co., as nominee of DTC, all payments with respect to principal of, redemption premium, if any, Purchase Price, and interest on, such Bond and all notices with respect to such Bond shall be made and given, respectively, pursuant to
DTC’s rules and procedures, or in the case of a successor Securities Depository, pursuant to any agreement among the Issuer, the Trustee, the Bond Registrar, and the Securities Depository. 
 (b) With respect to Bonds registered in the name of a Securities Depository (or its nominee) neither the Trustee, the Issuer nor the Company shall have
any obligation to any of its members or participants or to any person on behalf of whom an interest is held in the Bonds. 
  

 31 

 SECTION 2.17. CUSIP Numbers. The Issuer in issuing the Bonds may use “CUSIP” numbers (if
then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Bondholders; provided that any such notice may state that no representation is made as to the correctness of such
numbers either as printed on the Bonds or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Bonds, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers. There shall initially be separate “CUSIP” numbers for each Series of Bonds but if all Series of Bonds bear the same rate
of interest, they may all carry the same “CUSIP” number following the first Interest Payment Date. 
 SECTION 2.18. Restrictions
on Registration and Transfer of Bonds. Notwithstanding any other provision hereof, the Bonds may not be registered in the name of, or transferred to, any person except a Qualified Institutional Buyer; provided, however, pursuant to
Section 2.15, Bonds registered in the name of Cede & Co. or its nominee shall be deemed to comply with this Section so long as each beneficial owner of the Bonds is a Qualified Institutional Buyer.

in the Bond Fund is insufficient for such purpose on the date such payment is due. In the event that on the Business Day prior to the due date thereof, amounts on deposit in the Bond Fund are insufficient to pay the principal and/or interest due on

direction, maturing not later than the date or dates when the payments for which such moneys are held are to become due. Any such investments shall be held by or under the control of the Trustee and shall be deemed at all times a part of the Bond
Fund or the Debt Service Reserve Fund, as the case may be. Upon the occurrence of, and during the continuation of, an Event of Default, the Trustee shall no longer take investment instructions from the Company, but from a representative of the
Majority Holders. 
 The interest and income received upon such investments of the Bond Fund and any interest paid by the Trustee or any
other depository and any profit or loss resulting from the sale of any investment shall be added or charged to the extent received or paid and available for payment of amounts due on the Bonds, to the payment of the next succeeding payment due on
account of the Bonds and to the extent so applied, shall constitute payment in respect of the Agreement (notice of which payment shall be given by the Trustee to the Company), and any realized loss shall be made up by the Company (the direction of
the Company to make investments as aforesaid to include an agreement so to do). The interest and income received upon such investments of the Debt Service Reserve Fund shall be credited to the Debt Service Reserve Fund. 
 SECTION 8.3. Investment of Moneys in the Construction Fund. 
 (a) Moneys held for the credit of the Construction Fund shall, upon written direction by the Authorized Company Representative, be invested and reinvested by the Trustee as specified by the Authorized Company
Representative in any one or more of the following obligations or securities, to the extent permitted by State law, on which neither the Company nor any of its Affiliates is the obligor: (i) Governmental Obligations; (ii) debt obligations
which are 

  

 37 

 
(A) issued by any state or political subdivision thereof or any agency or instrumentality of such state or political subdivision, and (B) at the time of
purchase, rated “AAA” by S&P and rated “Aaa” by Moody’s; (iii) any bond, debenture, note, participation certificate or other similar obligation which is either (A) issued or guaranteed by the Federal National

America; (iv) U.S. denominated deposit account, certificates of deposit and banker’s acceptances with domestic commercial banks, which have a rating on their short-term certificates of deposit on the date of purchase of “A-1” by

“A-1” by S&P or “P-1” by Moody’s, without regard to gradation, and which matures not more than 270 days after the date of purchase; (vi) investment agreements with banks that at the time such agreement is executed
are rated by S&P or Moody’s in one of the two highest rating categories assigned by S&P or Moody’s (without regard to any refinement or gradation of rating category by numerical modifier or otherwise) or investment agreements with
non-bank financial institutions which, (A) all of the unsecured, direct long-term debt of either the non-banking financial institution or the related guarantor of such non-bank financial institution is rated by S&P or Moody’s at the
time such agreement is executed in one of the two highest rating categories (without regard to any refinement or gradation of rating category by numerical modifier or otherwise) for obligations of that nature; or (B) if such non-bank financial
institutions have no outstanding long-term debt that is rated, all of the short-term debt of either the non-banking financial institution or the related guarantor of such non-bank financial institution is rated by S&P or Moody’s in the
highest rating category (without regard to any refinement or gradation of the rating category by numerical modifier or otherwise) assigned to short term indebtedness by S&P or Moody’s, provided that if at any time after purchase the
provider of the investment agreement drops below the two highest rating categories assigned by S&P or Moody’s, the investment agreement must, within 30 days, either (1) be assigned to a provider rated in one of the two highest rating
categories or (2) be secured by the provider with collateral securities the fair market value of which, in relation to the amount of the investment agreement including principal and interest, is equal to at least 102%; (vii) investment
agreements with banks or non-bank financial institutions shall not be permitted if no rating is available with respect to debt of the investment agreement provider or the related guarantor of such provider; (viii) repurchase agreements with
respect to and secured by Government Obligations or by obligations described in clauses (ii) and (iii) above, which agreements may be entered into with a bank (including without limitation the Trustee or any of its affiliates), a trust
company, financial services firm or a broker dealer which is a member of the Securities Investors Protection Corporation, provided that (A) the Trustee or a custodial agent of the Trustee has possession of the collateral and that the collateral
is free and clear of third-party claims, (B) a master repurchase agreement or specific written repurchase agreement governs the transaction, (C) the collateral securities are valued no less frequently than monthly, and (D) the fair
market value of the collateral securities in relation to the amount of the repurchase obligation, including principal and interest, is equal to at least 103%, and (E) such obligations must be held in the custody of the Trustee or the

1933, and whose investments 
  

 38 

 
consist solely of Investments described in paragraphs (i) through (viii) above, including, without limitation, one or more money market mutual fund
portfolios of the Wells Fargo Advantage Funds or any other mutual fund for which the Trustee or any of its affiliates serve as an investment manager, administrator, servicing agent or custodian or subcustodian, notwithstanding that (x) the
Trustee or an affiliate of the Trustee receives fees from such funds for services rendered, (y) the Trustee charges and collects fees for services rendered pursuant to this Indenture, which fees are separate from the fees received from such
funds, and (z) services performed for such funds and pursuant to the Indenture may at times duplicate those provided to such funds by the Trustee or its affiliates. The Company acknowledges and agrees that the mutual funds referred to in the
final clause of the preceding sentence are not obligations of nor are they endorsed or guaranteed by the Trustee or any of its affiliates. Such investments shall have maturity dates, or shall be subject to redemption by the holder at the option of
the holder, on or prior to the dates the moneys invested therein will be needed as reflected by a statement of the Authorized Company Representative, which statement must be on file with the Trustee prior to any investment. 
 The Trustee shall be entitled to assume that any investment which at the time of purchase is a permitted investment hereunder remains a permitted
investment thereafter, absent receipt of written notice or actual knowledge of information to the contrary. 
 (b) All interest, income, or
other gain from the investment of moneys in the Construction Fund shall be retained therein and any loss resulting from the sale of any investment shall be charged to such Fund. 
 SECTION 8.4. No Liability for Investments. 
 (a) The Trustee may make any and all investments under this Article VIII through its own investment department or that of its affiliates or subsidiaries. 
 (b) The Trustee shall have no responsibility with respect to the compliance by the Company with respect to any covenant herein regarding investments made in accordance with this Article VIII, other than to use its
best reasonable efforts to comply with instructions from the Company regarding such investments. Since the making of such investments will be subject to the Company’s direction, the Trustee specifically disclaims any obligation to the Company
for any loss, fee, or other charge arising from, or tax consequences of, investments, reinvestments, and liquidation of investments pursuant to the provisions of this Section. 
 SECTION 8.5. Covenants Regarding Rebate. 
 (a) A special Rebate Fund is hereby established by the Issuer with the Trustee. The Rebate Fund shall be for the sole benefit of the United States of America and shall not be subject to the claim of any other person, including without
limitation the Bondholders. The Rebate Fund is established for the purpose of complying with section 148 of the Code and the Treasury Regulations promulgated pursuant thereto. The money deposited in the Rebate Fund, together with all investments
thereof and investment income therefrom, shall be held in trust and applied solely as provided in this section. The Rebate Fund is not a portion of the Trust Estate and is not subject to the lien of this Indenture. Notwithstanding the foregoing, the
Trustee with respect to the Rebate Fund is afforded all the rights, protections and immunities otherwise accorded to it hereunder. 
  

 39 

 (b) Unless the Bonds qualify for an exception to rebate under Section 148 of the Code, within ten
days after the close of each “Bond Year,” the Trustee shall receive from the Company a computation in the form of a certificate of an Authorized Company Representative of the amount of “Excess Earnings,” if any, for the period
beginning on the date of delivery of the Bonds and ending at the close of such “Bond Year” and the Company shall pay to the Trustee for deposit into the Rebate Fund an amount equal to the difference, if any, between the amount then in the
Rebate Fund and the Excess Earnings so computed. The term “Bond Year” means with respect to the Bonds each one year period ending on the anniversary of the date of delivery of the Bonds or such other period as may be elected by the Issuer
in accordance with the Regulations and notice of which election has been given to the Trustee. If, at the close of any Bond Year, the amount in the Rebate Fund exceeds the amount that would be required to be paid to the United States of America
under paragraph (d) below if the Bonds had been paid in full, such excess may be transferred from the Rebate Fund and paid to the Company upon its written direction, and the Company shall use such excess for such purposes for which, or to be
redeposited to such fund from which, such amounts were originally derived. 
 (c) In general, “Excess Earnings” for any period of
time means the sum of 
 (i) the excess of — 
 (A) the aggregate amount earned during such period of time on all “Nonpurpose Investments” (including gains on the disposition
of such obligations) in which “Gross Proceeds” of the issue are invested (other than amounts attributable to an excess described in this subparagraph (c)(i)), over 
 (B) the amount that would have been earned during such period of time if the “Yield” on such Nonpurpose Investments (other than
amounts attributable to an excess described in this subparagraph (c)(i)) had been equal to the yield on the issue, plus 
 (ii) any income during such period of time attributable to the excess described in subparagraph (c)(i) above. 
 The terms
Nonpurpose Investments, Gross Proceeds, and Yield shall have the meanings given to such terms in section 148 of the Code and the Regulations promulgated pursuant to such section. 
 (d) Upon written direction from the Company, the Trustee shall pay to the United States of America at least once every five years, to the extent that
funds are available in the Rebate Fund or otherwise provided by the Company, an amount that ensures that at least 90 percent of the Excess Earnings from the date of delivery of the Bonds to the close of the period for which the payment is being made
will have been paid. The Trustee shall pay to the United States of America not later than 60 days after the Bonds have been paid in full, to the extent that funds are available in the Rebate Fund or otherwise provided by the Company, 100 percent of
the amount then required to be paid under section 148(f) of the Code as a result of Excess Earnings, unless the Bonds qualify for the exception to rebate set forth in Section 148(f)(4)(B) of the Code or the Regulations thereunder. 

 

 40 

 (e) The amounts to be computed, paid, deposited or disbursed under this section shall be determined by
the Company acting on behalf of the Issuer within ten days after (i) each Bond Year after the date of issuance of each issue or series of Bonds and (ii) the date on which the Bonds have been paid in full, unless the Trustee shall have been
provided a Favorable Opinion with respect to the noncompliance with such requirements. By such date, the Company shall also notify, in writing, the Trustee and the Issuer of the determinations the Company has made and the payment to be made pursuant
to the provisions of this section. All such determinations shall be conclusive and binding on the Trustee and the Issuer. Upon written request of any registered owner of Bonds, the Company shall furnish to such registered owner of Bonds a
certificate (supported by reasonable documentation, which may include calculation by Bond Counsel or by some other service organization) showing compliance with this section and other applicable provisions of section 148 of the Code. 
 (f) The Trustee shall maintain a record of the periodic determinations by the Company of the Excess Earnings for a period beginning on the first
anniversary date of the issuance of the Bonds and ending on the date of the final retirement of the Bonds. Such records shall state each such anniversary date and contain a summary prepared by the Company of the manner in which the Excess Earnings,
if any, was determined. The Trustee shall provide to the Company periodic statements of transactions and investments with respect to the various funds and accounts created pursuant to this Indenture. Such statements shall be provided as part of the
Ordinary Services contemplated herein. In the event that the Company requests the Trustee to provide copies of the statements to a rebate consultant or other person for the purpose of performing analysis or calculations relating to arbitrage rebate
as required under this Indenture (or other financing agreement) or for any other reason, then the Trustee shall be entitled to additional compensation for its services with respect to providing such additional statements. 
 (g) If the Trustee shall declare the principal of the Bonds and the interest accrued thereon immediately due and payable as the result of an Event of
Default specified in this Indenture, or if the Bonds are optionally or mandatorily prepaid or redeemed prior to maturity as a whole in accordance with their terms, any amount remaining in any of the funds shall be transferred to the Rebate Fund to
the extent that the amount therein is less than the Excess Earnings computed by the Company as of the date of such acceleration or redemption, and the balance of such amount shall be used immediately by the Trustee for the purpose of paying
principal of, redemption premium, if any, and interest on the Bonds when due. In furtherance of such intention, the Issuer hereby authorizes and directs its President to execute any documents, certificates or reports required by the Code and to make
such elections, on behalf of the Issuer, which may be permitted by the Code as are consistent with the purpose for the issuance of the Bonds.

 The principal amount of the Bonds so required to be redeemed on
any such mandatory redemption date shall be reduced by the principal amount of any Bonds which, at least 45 days prior such redemption date, (1) shall have been acquired by the Trustee at the written direction of the Company, at a price not
exceeding the principal amount of such Bonds plus accrued interest to the date of purchase thereof and delivered to the Trustee for cancellation, or (2) shall have been redeemed pursuant to any other redemption provision herein and not
previously so credited. 
  

 42 

 If any Additional Bonds are designated as Series 2008A Bonds, the Supplemental Indenture relating to such
Additional Bonds shall specify any changes to the above mandatory redemption schedule. 
 (c) Extraordinary Mandatory Redemption.

 (i) Taxability. The Bonds shall be subject to mandatory redemption, at a redemption price equal to 106% the
principal amount being redeemed plus accrued interest to the redemption date on any date on or after the one hundred eightieth day (or such earlier date as may be designated by the Company) after a final determination by a court of competent
jurisdiction or an administrative agency (including the Internal Revenue Service), or receipt by the Company of an opinion of Bond Counsel obtained by the Company, to the effect the interest payable on the Bonds is or will be included in the gross
income of the owners thereof for federal income tax purposes, other than any Owner who is a “substantial user” of the Project or a “related person” within the meaning of Section 147(a) of the Code. Subject to the foregoing
provisions of this Section 9.1(c)(i), the Bonds shall be redeemed in whole unless, in the opinion of Bond Counsel mutually acceptable to the Issuer, the Trustee and the Company, the redemption of a portion of such Bonds would have the result
that interest payable on the Bonds remaining outstanding after such redemption would not be includable in the gross income for federal income tax purposes of any owner of any such Bonds. Any such partial redemption shall be in such amount as is
necessary to accomplish such result; and 
 (ii) Excess Proceeds. The Bonds are subject to mandatory redemption, in
part, on any date, to the extent that proceeds of the Bonds in a sufficient amount to redeem Bonds are transferred to the Bond Fund pursuant to Section 5.3 or 5.4 hereof, at a redemption price equal to the principal amount being redeemed plus
accrued interest to the redemption date. 
 (d) Extraordinary Optional Redemption. The Bonds shall be subject to optional redemption
by the Issuer, at the written direction of the Company, in whole or in part as described in Section 9.3 hereof, on any date, at a redemption price equal to the principal amount being redeemed plus accrued interest to the redemption date, if:

 (i) the Company shall have determined that the continued construction or operation of a Facility is impracticable,
uneconomical or undesirable due to (A) the imposition of taxes, other than ad valorem taxes currently levied upon privately owned property used for the same general purpose as such Facility, or other liabilities or burdens with respect to such
Facility or the operation thereof, (B) changes in technology, in environmental standards or legal requirements or in the economic availability of materials, supplies, equipment or labor or (C) destruction of or damage to all or part of
such Facility; 
 (ii) all or substantially all of a Facility shall have been condemned or taken by eminent domain;

  

 43 

 (iii) the construction or operation of a Facility shall have been enjoined or shall have
otherwise been prohibited by any order, decree, rule or regulation of any court or of any federal, state or local regulatory body, administrative agency or other governmental body; or 
 (iv) a Facility or portion thereof shall have been sold and the proceeds of sale shall not have been reinvested as provided in the
Guarantee. 
 Anything in this subsection (d) to the contrary notwithstanding, if any of the events described above shall have occurred
with respect to a portion, but not all, of the Project, the amounts of Bonds that may be redeemed shall not exceed an amount derived by multiplying the total principal amount of the Bonds by a fraction (a) the numerator of which is the cost of
the Project or portion thereof so affected and (b) the denominator of which is the total cost of the Project. 
 SECTION 9.2. Company
Direction of Optional Redemption. The Trustee shall call Bonds for optional redemption when and only when it shall have been notified by the Company to do so. The Company will give written notice of any optional redemption to the Trustee and the
Issuer as provided in Section 9.4 of this Indenture. 
 SECTION 9.3. Selection of Bonds to be Called for Redemption; Partial
Redemption. Except as otherwise provided herein or in the Bonds, the particular Bonds to be called for redemption shall be selected by the Trustee by lot or any other customary random method determined by the Trustee to be fair and reasonable
provided that a portion of a Bond may be redeemed only in Authorized Denominations. If less than all the Bonds are to be redeemed, such redemption must be in an amount which will result in the Bonds that remain outstanding being in Authorized
Denominations. The amount of any portion of Bonds redeemed shall be applied ratably to reduce the mandatory redemption schedule set forth in 9.1(b), provided that (a) the remaining mandatory redemption payments shall remain in Authorized
Denominations, and (b) the weighted average maturity of the remaining Bonds will be at least as long as the weighted average maturity of the Bonds immediately prior to such partial redemption. 
 SECTION 9.4. Notice of Redemption. 
 (a) The Company shall deliver notice to the Trustee and the Issuer of its intention to prepay the principal of, redemption premium, if any, and interest on the Bonds and cause the Bonds to be called for optional redemption at least ten
(10) Business Days prior to the date the Trustee gives notice to the Registered Owners of the Bonds of the proposed redemption of the Bonds. The Trustee shall cause notice of any redemption of Bonds hereunder, which notice shall be prepared by
the Company, to be mailed by first class mail, postage prepaid (except when DTC or a Securities Depository is the Registered Owner of all of the Bonds and except for any person or entity owning or providing evidence of ownership satisfactory to the
Trustee of a legal or beneficial ownership in at least $1,000,000 of principal amount of Bonds who so requests, in which cases, by certified mail, return receipt requested), to the Registered Owners of all Bonds to be redeemed at the registered
addresses appearing in the Bond Register kept for such purpose pursuant to Article II hereof. Each such notice shall (i) be mailed at least 30 days prior to the redemption date for Bonds, (ii) identify the Bonds to be redeemed if less

  

 44 

 
than all Bonds are to be redeemed (specifying the CUSIP numbers, if any, assigned to the Bonds), (iii) specify the redemption date and the redemption
price, (iv) state whether the notice is conditional or not as permitted by paragraph (b) hereof, and (v) state that on the redemption date the Bonds called for redemption will be payable at the office of the Trustee designated in such
notice, that from that date, provided funds have been deposited with the Trustee sufficient for redemption, interest will cease to accrue and that no representation is made as to the accuracy or correctness of the CUSIP numbers printed therein or on
the Bonds; provided, however, that the Bonds are registered with DTC or a successor Securities Depository, redemption notices will be sent to Cede & Co. pursuant to the procedures set forth in the DTC Letter of Representations or the
procedures of such successor Securities Depository. Any failure on the part of DTC or a successor Securities Depository, a direct participant or indirect participant to give such notice to the Owner or any defect therein shall not affect the
sufficiency or validity of any proceedings for the redemption of the Bonds. No defect affecting any Bond, whether in the notice of redemption or mailing thereof (including any failure to mail such notice), shall affect the validity of the redemption
proceedings for any other Bonds. 
 (b) Conditional Notice. If at the time of mailing of notice of an optional redemption there shall
not have been deposited with the Trustee moneys sufficient to redeem all the Bonds called for redemption, such notice may state that it is conditional, that is, subject to the deposit of the redemption moneys with the Trustee on or prior to the
redemption date, and such notice shall be of no effect unless such moneys are so deposited on or prior to the redemption date. If such redemption is not effectuated, the Trustee shall, at the expense of the Company, within five days thereafter, give
notice in the manner in which the notice of redemption was given that such moneys were not so received and shall rescind the redemption. 
 (c) Additional Notice of Redemption. In addition to the redemption notice required above, if there is more than one Registered Owner of the Bonds, further notice (the “Additional Notice”) shall be given by the Trustee as
set out below. No defect in the Additional Notice nor any failure to give all or any portion of the Additional Notice shall in any manner defeat the effectiveness of a call for redemption if notice is given as prescribed in paragraph (a) above.

 (i) Each Additional Notice shall contain the information required in paragraph (a) above for an official notice of
redemption plus (A) the date of the Bonds as originally issued; (B) the interest rate; (C) the Maturity Date; and (D) any other descriptive information needed to identify accurately the Bonds being redeemed. 
 (ii) Each Additional Notice shall be published one time in a financial newspaper or journal which regularly carries notices of redemption
of other obligations similar to the Bonds, such publication to be made at least 30 days prior to the date fixed for redemption. 
 (iii) Upon the payment of the redemption price of the Bonds being redeemed, each check or other transfer of funds issued for such purpose shall bear the CUSIP number identifying, by issue and maturity, the Bonds being redeemed with the
proceeds of such check or other transfer, provided that neither the Issuer, the Company, nor the Trustee shall be deemed to have made any representation as to the correctness of such CUSIP number. 
  

 45 

 (iv) Each Additional Notice shall be sent at least 30 days before the redemption date by
registered or certified mail, facsimile, or overnight delivery service to the following registered securities depositories: The Depository Trust Company of New York, New York and Philadelphia Depository Trust Company of Philadelphia, Pennsylvania
and to such other registered securities depositories as may be specified by the Company to the Trustee in writing and to one or more national information services that disseminate notices of redemption of obligations such as the Bonds as shall be
specified by the Company to the Trustee in writing. 
 (v) The Trustee’s agreement to give the additional notices
specified in this subsection (c) is made as a matter of courtesy and accommodation only and the Trustee shall incur no liability to any person for its failure to give such additional notices.

deposited with or paid to the Trustee pursuant to Article XVI hereof, shall, while held by the Trustee or any Paying Agent, constitute part of the Trust Estate and be subject to the lien hereof. Any moneys received by or paid to the Trustee pursuant
to any provision of the Agreement calling for the Trustee to hold, administer and disburse the same in accordance with the specific provisions of the Agreement shall be held, administered and disbursed pursuant to such provisions. The Issuer agrees
that if it shall receive any moneys pursuant to applicable provisions of the Agreement, it will forthwith upon receipt thereof pay the same over to the Trustee to be held, administered and disbursed by the Trustee in accordance with the provisions
of the Agreement pursuant to which the Issuer may have received the same. Furthermore, if for any reason the Agreement ceases to be in force and effect while any Bonds are outstanding, the Issuer agrees that if it shall receive any moneys derived
from the Project other than for payment of the Issuer’s annual fee, it will forthwith upon receipt thereof pay the same over to the Trustee to be held, administered and disbursed by the Trustee in accordance with provisions of the Agreement
that would be applicable if the Agreement were then in force and effect, and if there be no such provisions which would be so applicable, then the Trustee shall hold, administer and disburse such moneys solely for the discharge of the Issuer’s
obligations under this Indenture. 
 SECTION 10.11. Rights of Company Under Agreement. Nothing herein contained shall be deemed to
impair the rights and privileges of the Company set forth in the Agreement. The Issuer and the Trustee agree that the Company in its own name or in the name of the Issuer may enforce all of the rights of the Issuer, all obligations of the Trustee,
and all of the Company’s rights provided for in this Indenture. 
 SECTION 10.12. Tax Covenants. The Issuer shall at all times do
and perform all acts and things permitted by law and this Indenture which are necessary or desirable in order to assure that interest paid on the Bonds (or any of them) will be excluded from gross income for federal income tax purposes and shall
take no action that would result in such interest not being so excluded. Without limiting the generality of the foregoing, the Issuer agrees to comply with the provisions of the Tax Agreement. This covenant shall survive payment in full or
defeasance of the Bonds. 
 ARTICLE XI 
 EVENTS OF DEFAULT AND REMEDIES 
 SECTION 11.1. Events of Default Defined. Each of the following shall be an “Event of
Default” hereunder: 
 (a) Payment of the principal or redemption price of any Bond is not made when it becomes due and payable at
maturity or upon call for redemption; or 
  

 48 

 (b) Payment of any interest on any Bond is not made when it becomes due and payable; or 
 (c) The occurrence and continuance of any “Event of Default” under the Agreement; or 
 (d) Default in the payment of any other amount required to be paid under this Indenture or in the performance or observance of any other of the
covenants, agreements or conditions contained in this Indenture, or in the Bonds issued under this Indenture, and continuance thereof for a period of 90 days after written notice specifying such failure and requesting that it be remedied shall have
been given to the Issuer and the Company by the Trustee, which may give such notice in its discretion and shall give such notice at the written request of the holders of not less than 25% in principal amount of the Bonds then outstanding, unless the
Trustee, or the Trustee and holders of a principal amount of Bonds not less than the principal amount of Bonds the holders of which requested such notice, as the case may be, shall agree in writing to an extension of such period prior to its
expiration; provided, however, that the Trustee, or the Trustee and the holders of such principal amount of Bonds, as the case may be, shall be deemed to have agreed to an extension of such period if corrective action is instituted by the Issuer, or
the Company on behalf of the Issuer, within such period and is being diligently pursued; or 
 (e) The occurrence and continuance of any
“Event of Default” under, and as defined in, the Guarantee. 
 SECTION 11.2. Acceleration and Annulment Thereof. If any
Event of Default occurs and is continuing, the Trustee may, and upon written request of the owners of at least 25% in principal amount of all Bonds then Outstanding shall, by notice in writing to the Issuer and the Company, declare the principal of
and accrued interest on all Bonds then Outstanding to be immediately due and payable; and upon such declaration the said principal, together with interest accrued thereon to the date of acceleration, shall become due and payable immediately at the
place of payment provided therein, anything in this Indenture or in the Bonds to the contrary notwithstanding. Upon the occurrence of any acceleration hereunder, the Trustee shall immediately declare all payments under the Agreement pursuant to
Section 5.03 thereof to be due and payable immediately. 
 Immediately after any acceleration hereunder, the Trustee, to the extent it
has not already done so, shall notify in writing the Issuer, the Company, and the Paying Agent of the occurrence of such acceleration. Upon the occurrence of any acceleration hereunder, the Trustee shall notify by first class mail, postage prepaid,
the owners of all Bonds Outstanding of the occurrence of such acceleration. 
 If, after the principal of the Bonds has become due and
payable, all arrears of interest upon the Bonds are paid by the Issuer, and the Issuer also performs all other things in respect to which it may have been in default hereunder and pays the reasonable charges of the Trustee and the Bondholders,
including reasonable and necessary attorneys’ fees and expenses, then, and in every such case, the owners of a majority in principal amount of the Bonds then Outstanding, by written notice to the Issuer and to the Trustee, may annul such
acceleration and its consequences, 

  

 49 

 
and such annulment shall be binding upon the Trustee and upon all owners of Bonds issued hereunder. No such annulment shall extend to or affect any
subsequent default or impair any right or remedy consequent thereon. The Trustee shall forward a copy of any notice from Bondholders received by it pursuant to this paragraph to the Company. Immediately upon such annulment, the Trustee shall cancel,
by notice to the Company, any demand for prepayment of all amounts due under the Agreement made by the Trustee pursuant to this Section. The Trustee shall promptly give written notice of such annulment to the Issuer, the Company, the Collateral
Trustee, the Paying Agent, and, if notice of the acceleration of the Bonds shall have been given to the Bondholders, shall give notice thereof to the Bondholders. 
 SECTION 11.3. Other Remedies. If any Event of Default occurs and is continuing, the Trustee, before or after the principal of the Bonds becomes immediately due and payable, may enforce each and every right
granted to it under the Agreement and any supplements or amendments thereto. In exercising such rights and the rights given the Trustee under this Article, the Trustee shall take such action as, in the judgment of the Trustee applying the standards
described in Section 12.6, would best serve the interests of the Bondholders. 
 SECTION 11.4. Legal Proceedings by Trustee. If
any Event of Default has occurred and is continuing, the Trustee in its discretion may, and upon the written request of the owners of a majority in principal amount of all Bonds then Outstanding and receipt of indemnity to its satisfaction shall,
subject to the provisions of Article XII hereof, in its own name: 
 (i) By mandamus, or other suit, action or proceeding at
law or in equity, enforce all rights of the Bondholders, including the right to require the Issuer to enforce any rights under the Agreement and to require the Issuer to carry out any other provisions of this Indenture for the benefit of the
Bondholders and to perform its duties under the Act; 
 (ii) Bring suit to enforce the Bonds; 
 (iii) By action or suit in equity require the Issuer to account as if it were the trustee of an express trust for the Bondholders; and

 (iv) By action or suit in equity enjoin any acts or things which may be unlawful or in violation of the rights of the
Bondholders. 
 Notwithstanding anything to the contrary in this Indenture, the Issuer shall have no obligation to and instead the Trustee
may, without further direction from the Issuer, take any and all steps, actions and proceedings, to enforce any or all rights of the Issuer (other the Unassigned Rights of the Issuer) under this Indenture or the Agreement, including, without
limitation, the rights to enforce the remedies upon the occurrence and continuation of an Event of Default and the obligations of the Company under the Agreement. 
 SECTION 11.5. Discontinuance of Proceedings by Trustee. If any proceeding commenced by the Trustee on account of any Event of Default is discontinued or is determined adversely to the Trustee, then the Company,
the Issuer, the Trustee and the Bondholders shall be restored to their former positions and rights hereunder as though no such proceedings had been commenced. 
  

 50 

 SECTION 11.6. Majority Holders May Direct Proceedings. The owners of a majority in principal
amount of the Bonds then Outstanding shall have the right, after furnishing indemnity satisfactory to the Trustee, to direct the method and place of conducting all remedial proceedings by the Trustee hereunder, provided that (i) such directions
shall not be otherwise than in accordance with law or the provisions of this Indenture and (ii) the Trustee shall have the right to decline to follow any such direction which in the reasonable opinion of the Trustee conflicts with law or with
this Indenture or would be unjustly prejudicial to Bondholders not parties to such direction. 
 SECTION 11.7. Limitations on Actions by
Bondholders. No Bondholder shall have any right to pursue any remedy hereunder unless: 
 (i) the Trustee shall have been
given written notice of an Event of Default, 
 (ii) the owners of at least a majority in principal amount of all Bonds then
Outstanding shall have requested the Trustee, in writing, to exercise the powers hereinabove granted or to pursue such remedy in its or their name or names, 
 (iii) the Trustee shall have been offered indemnity satisfactory to it against reasonable costs, expenses and liabilities, including,
without limitation, reasonable costs and expenses of its counsel, except that no offer of indemnification shall be required solely for a declaration of acceleration under Section 11.2, and 
 (iv) the Trustee shall have failed to comply with such request within a reasonable time. 
 Notwithstanding the foregoing provisions of this Section or any other provision of this Indenture, the obligation of the Issuer shall be absolute and
unconditional to pay hereunder, but solely from the Revenues and other funds pledged under this Indenture, the principal or redemption price of, and interest on, the Bonds to the respective owners thereof on the respective due dates thereof, and
nothing herein shall affect or impair the right of action, which is absolute and unconditional, of such owners to enforce such payment. 
 SECTION 11.8. Trustee May Enforce Rights Without Possession of Bonds. All rights under this Indenture and the Bonds may be enforced by the Trustee without the possession of any Bonds or the production thereof at the trial or other
proceedings relative thereto, and any proceeding instituted by the Trustee shall be brought in its name for the ratable benefit of the owners of the Bonds. 
 SECTION 11.9. Remedies Not Exclusive. No remedy herein conferred is intended to be exclusive of any other remedy or remedies, and each remedy is in addition to every other remedy given hereunder or now or
hereafter existing at law or in equity or by statute. 
 SECTION 11.10. Delays and Omissions Not to Impair Rights. No delays or
omission in respect of exercising any right or power accruing upon any default shall impair such right or power or be a waiver of such default, and every remedy given by this Article may be exercised from time to time and as often as may be deemed
expedient. 
  

 51 

 SECTION 11.11. Application of Moneys in Event of Default. Any moneys received by the Trustee under
this Article shall be applied in the following order: 
 (i) To the payment of the reasonable costs and expenses of the
Trustee, including reasonable counsel fees and expenses, any disbursements of the Trustee with interest thereon at the prime rate of the Trustee and its reasonable compensation; and 
 (ii) To the payment of principal or redemption price (as the case may be) and interest then owing on the Bonds, and in case such moneys
shall be insufficient to pay the same in full, then to the payment of principal or redemption price and interest ratably, without preference or priority of one over another or of any installment of interest over any other installment of interest;
and 
 (iii) To the payment of reasonable costs and expenses of the Issuer, including reasonable counsel fees, incurred in
connection with the Event of Default. 
 The surplus, if any, shall be paid to the Company. 
 ARTICLE XII 
 THE TRUSTEE 
 SECTION 12.1. Acceptance of Trust. The Trustee accepts and agrees to execute the trusts hereby created, but only upon the additional terms set
forth in this Article XII, to all of which the Issuer, the Trustee (as Trustee, Paying Agent, and Bond Registrar), the Company and the Bondholders agree. 
 SECTION 12.2. No Responsibility for Recitals, etc. The recitals, statements and representations in this Indenture or in the Bonds, save only the Trustee’s Certificate of Authentication upon the Bonds, have
been made by the Issuer and not by the Trustee; and the Trustee shall be under no responsibility for the correctness thereof, or for the validity, priority, recording or re recording, filing or re-filing of this Indenture or the Agreement or any
financing statements or amendments thereto, other than continuation statements, or for insuring the Project or collecting any insurance moneys, or for the validity of the execution by the Issuer of this Indenture or of any supplements thereto or
instruments of further assurance, or for the validity or sufficiency of the security afforded by this Indenture or the Bonds issued hereunder or intended to be secured hereby, or as to the maintenance of the security hereof. The Trustee shall not be
bound to ascertain or inquire as to the performance or observance of any covenants, conditions or agreements on the part of the Issuer or on the part of the Company hereunder or under the Agreement, except as expressly provided herein or in the
Agreement. 
 The Trustee shall not be accountable for the application of the proceeds of any Bonds authenticated or delivered hereunder
which has been made by or on behalf of the Company or the Issuer. 
 SECTION 12.3. Trustee May Act Through Agents; Answerable Only for
Willful Misconduct or Negligence. The Trustee may exercise any powers hereunder and perform any 

  

 52 

 
duties required of it through attorneys, agents, officers or employees, and shall be entitled to rely on the advice of Counsel concerning all questions
hereunder or under the Agreement. The Trustee shall not be answerable for the default, negligence or misconduct of any attorney or agent selected by it with reasonable care. Except as otherwise provided herein, the Trustee shall not be answerable
for the exercise of any discretion or power under this Indenture nor for anything whatsoever in connection with the trust hereunder, except only its own willful misconduct or negligence. 
 SECTION 12.4. Compensation. The Company shall pay to the Trustee such compensation for its services hereunder as is specified in the Agreement or
such other written agreement between the Company and the Trustee, and also all its reasonable Ordinary Expenses and Extraordinary Expenses and disbursements, including the reasonable fees, costs and expenses of its counsel (including in-house
counsel and legal staff). If the Company shall have failed to make any such payment within a reasonable time, the Trustee shall have, in addition to any other rights hereunder, a claim, prior to the Bondholders, for the payment of its compensation
and the reimbursement of its expenses (both ordinary and extraordinary) and any advances made by it upon the moneys and obligations in the Bond Fund, except for moneys or obligations held by the Trustee for the payment of particular Bonds. When the
Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01(c) of the Agreement, the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services
are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law. 
 The provisions of this Section shall survive the termination of this Indenture. 
 SECTION 12.5. Notice of Default; Right to
Investigate. The Trustee shall, within the later of (i) 30 days after the occurrence thereof, or (ii) 15 days after it obtains actual knowledge thereof, give written notice by first class mail to registered owners of Bonds of all
Events of Default known to the Trustee, unless such Events of Default have been remedied. The Trustee shall not be deemed to have notice of any Event of Default under Section 11.1(c), (d),or (e) (other than payment defaults under Sections
6.01(a) of the Agreement) unless notified in writing of such default by the owners of at least 25% in principal amount of all Bonds then Outstanding or if it has actual notice thereof. The Trustee may, however, at any time require of the Issuer full
information as to the performance of any covenant hereunder; and, if information satisfactory to it is not forthcoming, the Trustee may make or cause to be made, at the expense of the Company, an investigation into the affairs of the Issuer related
to this Indenture. Copies of any notice required by this Section 12.5 shall also be sent to each Paying Agent. 
 SECTION 12.6.
Obligation to Act. Except during the continuance of an Event of Default, the Trustee shall undertake to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be
read into this Indenture against the Trustee. If any Event of Default shall have occurred and be continuing, the Trustee shall exercise such of the rights and remedies vested in it by this Indenture and shall use the same degree of care in their
exercise as a prudent person would exercise or use in the circumstances in the conduct of his own affairs. The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of
any of the Bondholders pursuant to this Indenture unless such Bondholders shall 

  

 53 

 
have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred in compliance with
such request or direction. Wherever, in this Indenture provision is made for indemnity by the owners of the Bonds, if the owner providing such indemnity has an aggregate net worth or net asset value of at least $50,000,000, as set forth in its most
recent audited financial statements or as otherwise satisfactorily demonstrated to the Trustee, the Trustee may not require any indemnity bond or other security for such indemnity. In any case where more than one owner is providing indemnity, such
indemnity shall be several and not joint and, as to each owner, such indemnity obligations shall not exceed its percentage interest of outstanding Bonds. 
 SECTION 12.7. Reliance. The Trustee may act on any requisition, resolution, notice, telegram, request, consent, direction, waiver, certificate, statement, affidavit, voucher, bond, or other paper or document
which it in good faith believes to be genuine and to have been passed or signed by the proper persons or to have been prepared and furnished pursuant to any of the provisions of this Indenture, and the Trustee shall be under no duty to make any
investigation as to any statement contained in any such instrument, but may accept the same as conclusive evidence of the accuracy of such statement. 
 SECTION 12.8. Trustee May Deal in Bonds. The Trustee may in good faith buy, sell, own, hold and deal in any of the Bonds and may join in any action which any Bondholders may be entitled to take with like effect
as if the Trustee were not a party to this Indenture. The Trustee may also engage in or be interested in any financial or other transaction with the Issuer or the Company. 
 SECTION 12.9. Resignation of Trustee. The Trustee may resign and be discharged of the trusts created by this Indenture by written resignation
filed with the Issuer and the Company not fewer than 60 days before the date when it is to take effect. Such resignation shall take effect only upon the appointment and acceptance of a successor trustee. 
 SECTION 12.10. Removal of Trustee. Any Trustee hereunder may be removed at any time by an instrument appointing a successor to the Trustee so
removed, executed by the Majority Holders and filed with the Trustee and the Issuer. A successor Trustee may be appointed by the Majority Holders in the same instrument. Subject to Section 12.11 hereof, if a successor Trustee does not take
office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, the Issuer, or the holders of at least 25% in principal amount of the outstanding Bonds may petition, at the expense of the Company, a court
of competent jurisdiction for the appointment of a successor Trustee. Such removal shall take effect only upon the appointment and acceptance of a successor Trustee. 
 SECTION 12.11. Appointment of Successor Trustee. If the Trustee or any successor trustee resigns or is removed or dissolved, or if its property or business is taken under the control of any state or federal
court or administrative body, a vacancy shall forthwith exist in the office of the Trustee, and the Issuer, at the direction of the Company, shall appoint a successor and shall mail notice of such appointment to registered owners of the Bonds. If
the Issuer fails to make such appointment promptly, the owners of a majority in principal amount of the Bonds then Outstanding may do so. 
  

 54 

 SECTION 12.12. Qualification of Successor. A successor trustee shall be a national banking
association with trust powers or a bank and trust company or a trust company having capital and surplus of at least $50,000,000 and rated Baa3/P-3 or better by Moody’s or be otherwise acceptable to Moody’s if the Bonds are then rated by
Moody’s or BBB- or better by S&P or be otherwise acceptable by S&P if the Bonds are then rated by S&P, if there be one able and willing to accept the trust on reasonable and customary terms. 
 SECTION 12.13. Instruments of Succession. Any successor trustee shall execute, acknowledge and deliver to the Issuer an instrument accepting such
appointment hereunder; and thereupon such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the estates, properties, rights, powers, trusts, duties and obligations of its predecessor in the trust
hereunder, with like effect as if originally named Trustee herein. The Trustee ceasing to act hereunder shall pay over to the successor trustee all moneys held by it hereunder; and, upon request of the successor trustee, the Trustee ceasing to act
and the Issuer shall execute and deliver an instrument transferring to the successor trustee all the estates, properties, rights, powers and trusts hereunder of the Trustee ceasing to act. 
 SECTION 12.14. Merger of Trustee. Any corporation or association into which any Trustee hereunder may be merged or with which it may be
consolidated, or any corporation or association resulting from any merger or consolidation to which any Trustee hereunder shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee,
shall be the successor trustee under this Indenture, without the execution or filing of any paper or any further act on the part of the parties hereto, anything herein to the contrary notwithstanding. 
 SECTION 12.15. Trustee Not Required to Expend or Risk Own Funds. No provision of this Indenture, the Agreement, the Guarantee, or any other
financing document pertaining to the Bonds shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers. The
Trustee shall not be required to give bond or surety to act under this Indenture. 
 SECTION 12.16. Right of Trustee to Pay Taxes and
Other Charges. In case any tax, assessment or governmental or other charge upon any part of the trust estate is not paid as required herein, the Trustee may, but shall not be required to, pay such tax, assessment or governmental or other charge,
without prejudice, however, to any rights of the Trustee or the Bondholders hereunder arising in consequence of such failure; and any amount at any time so paid under this Section 12.16, with interest thereon from the date of payment at the
prime rate of the Trustee, shall become so much additional indebtedness secured by this Indenture, and the same shall be paid out of the proceeds of Revenues collected from the property herein conveyed, if not otherwise caused to be paid; but the
Trustee shall be under no obligation to make any such payment unless it shall have been requested to do so by the owners of at least 25% in aggregate principal amount of all Bonds then Outstanding and shall have been provided with adequate funds for
the purpose of such payment. 
 SECTION 12.17. Trust Estate may be Vested in Separate or Co Trustee. It is the purpose of this
Indenture that there shall be no violation of any law of any jurisdiction (including 

  

 55 

 
particularly the law of the State) denying or restricting the right of banking corporations or associations to transact business as trustee in such
jurisdiction. It is recognized that in case of litigation under this Indenture or the Agreement, and in particular in case of the enforcement of either on default, or in case the Trustee deems that by reason of any present or future law of any
jurisdiction it may not exercise any of the powers, rights or remedies herein granted to the Trustee or hold title to the trust estate, in trust, as herein granted, or take any other action which may be desirable or necessary in connection
therewith, it may be necessary that the Trustee appoint an additional individual or institution as a separate or co trustee. The expense of any separate or co-trustee shall be borne by the Company. The following provisions of this Section 12.17
are adapted to these ends. 
 In the event that the Trustee appoints an additional individual or institution as a separate or co trustee,
each and every remedy, power, right, claim, demand, cause of action, immunity, estate, title, interest and lien expressed or intended by this Indenture to be exercised by or vested in or conveyed to the Trustee with respect thereto shall be
exercisable by and vested in such separate or co trustee but only to the extent necessary to enable such separate or co trustee to exercise such powers, rights and remedies, and every covenant and obligation necessary to the exercise thereof by such
separate or co trustee shall run to and be enforceable by either of them. 
 Should any deed, conveyance or instrument in writing from the
Issuer be required by the separate trustee or co trustee so appointed by the Trustee for more fully and certainly vesting in and confirming to him such properties, rights, powers, trusts, duties and obligations, any and all such deeds, conveyances
and instruments in writing shall, on request, be executed, acknowledged and delivered by the Issuer. In case any separate trustee or co trustee, or a successor to either, shall become incapable of acting, resign or be removed, all the estate
properties, rights, powers, trusts, duties and obligations of such separate trustee or co trustee, so far as permitted by law, shall vest in and be exercised by the Trustee until the appointment of a new trustee or successor to such separate trustee
or co trustee. 
 No trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder.

 SECTION 12.18. Reliance Upon Counsel. The Trustee may consult with Counsel satisfactory to it, and the opinion of such Counsel
selected by the Trustee shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by such Trustee under this Indenture, the Agreement or the Guarantee in good faith and in reliance thereon.

 SECTION 12.19. No Implied Duties. The Trustee shall be obligated to perform such duties and only such duties as are herein and in
the Bonds specifically set forth and as are required by applicable law and no implied duties or obligations of the Trustee shall be read into this Indenture or the Bonds. The permissive rights of the Trustee to do things enumerated in this Indenture
shall not be construed as a duty. 
 SECTION 12.20. No Responsibility for Securities Laws. The Trustee shall have no responsibility
with respect to any information in any offering memorandum or other disclosure material distributed with respect to the Bonds or for compliance with securities laws in connection with the issuance and sale of the Bonds. 
  

 56 

 SECTION 12.21. No Responsibility for Yield Covenants. Except as specified in Section 8.5
hereof, the Trustee shall have no responsibility with respect to compliance by the Issuer or the Company with Section 148 of the Code or any covenant in this Indenture or in the Agreement regarding yields on investments. 
 SECTION 12.22. No Responsibility for Filings. The Trustee shall not be responsible for (i) the validity, priority, recording, rerecording,
filing, or refiling of this Indenture or any supplemental indenture; (ii) any instrument or document of further assurance or collateral assignment; (iii) any financing statements or amendments or modifications thereto other than
continuation statements; (iv) the validity of the execution of the Issuer of this Indenture or any supplemental indenture or documents of further assurance; (v) the sufficiency of the security of the Bonds issued hereunder; and
(vi) the value of or title to the Project. 
 SECTION 12.23. Trustee Notices. Except as otherwise expressly provided hereunder,
the Trustee shall not be required to give or furnish any notice, demand, report, reply, statement, advice or opinion to the Company or any other Person, and the Trustee shall not incur any liability for its failure or refusal to give or furnish the
same unless obligated or required to do so by express provisions hereof. 
 ARTICLE XIII 
 THE PAYING AGENT 
 SECTION 13.1. The
Paying Agent. 
 (a) The Paying Agent shall agree to 
 (i) hold all sums held by it for the payment of the principal or redemption price of, or interest on, Bonds in trust for the benefit of
the owners of such Bonds until such sums shall be paid to such owners or otherwise disposed of as herein provided; 
 (ii) at
any time during the continuance of any default in the payment of principal or redemption price of or interest on the Bonds, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent; and

 (iii) keep such books and records as shall be consistent with prudent industry practice and to make such books and records
available for inspection by the Issuer, the Trustee, and the Company at all reasonable times. 
 (b) The Paying Agent shall be a corporation
duly organized under the laws of the United States of America or any state or territory thereof, or a bank with trust powers or a trust company having a combined capital stock, surplus and undivided profits of at least $50,000,000 and authorized by
law to perform all the duties imposed upon it by this Indenture. The Paying Agent may at any time resign and be discharged of the duties and obligations created 

  

 57 

 
by this Indenture by giving at least 60 days’ notice to the Issuer, the Trustee, and the Company. In the event that the Issuer, at the request of the
Company, shall fail to appoint a successor Paying Agent, upon the resignation or removal of the Paying Agent, the Trustee shall either appoint a Paying Agent or itself act as Paying Agent until the appointment of a successor Paying Agent. Any
successor Paying Agent shall either be rated Baa/P-3 or better by Moody’s or be otherwise acceptable to Moody’s if the Bonds are then rated by Moody’s. The Paying Agent may be removed at any time by an instrument signed by the
Company, filed with the Issuer and the Trustee. 
 In the event of the resignation or removal of the Paying Agent, the Paying Agent shall
deliver any Bonds and moneys held by it in such capacity to its successor or, if there is no successor, to the Trustee. 
 (c) The Paying
Agent in performing its duties hereunder shall be entitled to the same protective provisions in the performance of its duties as are specified in Article XII of this Indenture with respect to the Trustee hereunder to the same extent and as fully for
all intents and purposes as though the Paying Agent had been expressly named therein in place of such Trustee and as though the applicable provisions of Article XII of this Indenture had been set forth herein at length. 
 SECTION 13.2. Notices. The Trustee shall, within 30 days of the resignation or removal of the Paying Agent or the appointment of a successor
Paying Agent, give notice thereof by first class mail, postage prepaid, to the owners of the Bonds. 
 ARTICLE XIV 
 ACTS OF BONDHOLDERS; EVIDENCE OF OWNERSHIP 
 SECTION 14.1. Acts of Bondholders; Evidence of Ownership. Except as otherwise stated herein, any action to be taken by Bondholders may be evidenced by one or more concurrent written instruments of similar tenor signed or executed by
such Bondholders (or their beneficial owners) in person or by an agent appointed in writing. The initial purchasers of the Bonds from the Underwriter are hereby acknowledged by the Trustee as the beneficial owners thereof. The fact and date of the
execution by any person of any such instrument may be proved by acknowledgment before a notary public or other officer empowered to take acknowledgments or by an affidavit of a witness to such execution. Where such execution is by an officer of a
corporation or a member of a partnership, on behalf of such corporation or partnership, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or
the authority of the person executing the same, may also be proved in any other manner which the Trustee deems sufficient. The ownership of the Bonds shall be proved by the Bond Register. Any action by the owner of any Bond shall bind all future
owners of the same Bond in respect of anything done or suffered by the Issuer or the Trustee in pursuance thereof. 
  

 58 

 ARTICLE XV 
 AMENDMENTS AND SUPPLEMENTS 
 SECTION 15.1. Amendments and Supplements Without Bondholders’
Consent. This Indenture may be amended or supplemented at any time and from time to time, without the consent of the Bondholders, but with the consent of the Paying Agent if the amendment or supplement would materially adversely affect or alter
the duties or obligations of the Paying Agent under this Indenture, by a supplemental indenture authorized by a resolution of the Issuer and filed with the Trustee, for one or more of the following purposes: 
 (i) to add additional covenants of the Issuer or to surrender any right or power herein conferred upon the Issuer;

 Before the Issuer and the Trustee shall enter into any supplemental indenture pursuant to this Section,

 SECTION 15.2. Amendments With Bondholders’ Consent. This Indenture may be amended or supplemented
at any time or from time to time, except with respect to (i) the principal, redemption price, and interest payable upon any Bonds, (ii) the Interest Payment Dates, the dates of maturity or the redemption provisions of any Bonds, and
(iii) this Article, by a supplemental indenture consented to by the Company, and if the amendment or supplement would materially adversely affect or alter the duties or obligations of the Paying Agent under this Indenture, with the consent of
the Paying Agent, and approved by the Majority Holders which would be affected by the action proposed to be taken. This Indenture may be amended with respect to the matters enumerated in clauses (i) through (iii) of the preceding sentence

 SECTION 15.6. Consent of Company. Anything herein to the contrary notwithstanding, so long as the
Company is not in default under the Agreement, a supplemental indenture under this Article which affects any right of the Company shall not become effective unless and until the Company shall have consented in writing to the execution and delivery

 ARTICLE XVI 
 DEFEASANCE 
 SECTION 16.1. Defeasance. 
 (a) If the Issuer shall pay or cause to be paid to the holders and owners of the Bonds the principal of and interest to become due thereon at the times
and in the manner stipulated therein, and if the Issuer shall keep, perform and observe all and singular the covenants and promises in the Bonds and in this Indenture expressed as to be kept, performed and observed by it on its part and shall pay or
cause to be paid all other sums payable hereunder by the Issuer, then these presents and the estate and rights hereby granted shall cease, terminate and be void, and thereupon the Trustee shall cancel and discharge the lien of this Indenture, and
execute and deliver to the Issuer such instruments in writing as shall be requisite to satisfy the lien hereof, and reconvey to the Issuer the estate hereby conveyed, and assign and deliver to the Issuer any property at the time subject to the lien
of this Indenture which may then be in its possession, except moneys or Governmental Obligations held by it for the payment of the principal of and interest on the Bonds. 
 (b) Provision for the payment of Bonds shall be deemed to have been made when the Trustee holds in the Bond Fund, in trust and irrevocably set aside exclusively for such payment, (i) moneys sufficient to make
such payment of principal, redemption premium, if any, and interest on the Bonds; and/or (ii) noncallable, nonprepayable Governmental Obligations (provided that in either case the Trustee shall have received a Favorable Opinion) maturing as to
principal and interest in such amounts and at such times as will provide sufficient moneys (without consideration of any reinvestment thereof) to make such payment of principal, redemption premium, if any, and interest on the Bonds. 
 No Bonds in respect of which a deposit under clause (i) or (ii) above has been made shall be deemed paid within the meaning of this Article
unless the Trustee is satisfied that the amounts deposited are sufficient to make all payments that might become due on the Bonds, with respect to which the Trustee may rely on a verification certificate or report of independent certified public
accountants, a copy of which certificate or report shall also be furnished to each Rating Agency then rating the Bonds at the request of the Company. Neither the obligations nor moneys deposited with the Trustee pursuant to this Section shall be
withdrawn or used for any purpose other than, and shall be segregated and held in trust for, the payment of the principal, redemption price and interest on the Bonds with respect to which such deposit has been made. In the event that such moneys or
obligations are to be applied to the payment of principal or 

  

 61 

 
redemption price of any Bonds more than 60 days following the deposit thereof with the Trustee, the Trustee shall mail a notice to the owners of the Bonds to
be redeemed or deemed paid or redeemed, stating that such moneys or obligations have been deposited and identifying the Bonds for the payment of which such moneys or obligations are being held to all owners of Bonds for the payment of which such
moneys or obligations are being held at their registered addresses and to each Rating Agency then rating the Bonds at the request of the Company. 
 (c) Anything in Article XVI to the contrary notwithstanding, if moneys or Governmental Obligations have been deposited or set aside with the Trustee pursuant to this Article for the payment of the principal, or redemption price of the Bonds
and the interest thereon and the principal or redemption price of such Bonds and the interest thereon shall not have in fact been actually paid in full, no amendment to the provisions of this Article shall be made without the consent of the owner of
each of the Bonds affected thereby. 
 The Issuer or the Company may at any time surrender to the Trustee for cancellation by it any Bonds
previously authenticated and delivered hereunder, which the Issuer or the Company may have acquired in any manner whatsoever, and such Bonds, upon such surrender and cancellation, shall be deemed to be paid and retired. 
 ARTICLE XVII 
 MISCELLANEOUS 
 SECTION 17.1. No Personal Recourse. No recourse shall be had for any claim based on the Agreement, this Indenture or the Bonds against any member,
officer, agent or employee, past, present or future, of the Issuer or of any successor body as such, either directly or through the Issuer or any such successor body, under any constitutional provision, statute or rule of law, or by the enforcement
of any assessment or by any legal or equitable proceeding or otherwise. 
 SECTION 17.2. Deposit of Funds for Payment of Bonds. If the
principal or redemption price of any Bonds becoming due, either at maturity or by call for redemption or otherwise, together with all interest accruing thereon to the due date, has been paid or provision therefor made in accordance with
Section 16.1, all interest on such Bonds shall cease to accrue on the due date and all liability of the Issuer with respect to such Bonds shall likewise cease, except as hereinafter provided. Thereafter the owners of such Bonds shall be
restricted exclusively to the funds so deposited for any claim of whatsoever nature with respect to such Bonds, and the Trustee shall hold such funds in trust for such owners. 
 Moneys which remain unclaimed two years after the due date shall, at the written request of the Company, and if the Company is not, at the time, to the
knowledge of the Trustee, in default with respect to any covenant in the Agreement or the Bonds, be paid to the Company pursuant to its payment instructions, and the owners of the Bonds for which the deposit was made shall thereafter be limited to a
claim against the Company. Such moneys shall be held in trust uninvested without any obligation for the payment of interest thereon; provided, however, that before the repayment of such moneys to the Company as aforesaid, (i) the Trustee shall
(at the cost of the Company) first mail to the Holders of any Bonds remaining unpaid, at the addresses shown on the registration books maintained by the Trustee, a notice, in such form as 

  

 62 

 
may be deemed appropriate by the Trustee with respect to the Bonds so payable and not presented and with respect to the provisions relating to the repayment
to the Company of the moneys held for the payment thereof, and (ii) the Company shall expressly agree to indemnify the Issuer and the Trustee with respect to the payment of any Bonds so payable and not presented for payment as of the date of
such repayment to the Company. 
 SECTION 17.3. No Rights Conferred on Others. Nothing herein contained shall confer any right upon
any person other than the parties hereto, the Company and the owners of the Bonds. 
 SECTION 17.4. Severability. If any term or
provision of this Indenture or the Bonds or the application thereof for any reason or circumstance shall to any extent be held invalid or unenforceable, the remaining provisions or the application of such term or provision to persons and situations
other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and provision hereof and thereof shall be valid and enforced to the fullest extent permitted by law. 
 SECTION 17.5. Notices. Unless otherwise provided hereunder or in the Agreement, all notices, certificates or other communications hereunder to be
given by any of the following parties to any of the other following parties shall be deemed to have been sufficiently given and received by such parties only upon actual receipt and delivery thereof by mail, overnight delivery, by Electronic Notice,

 THE FOLLOWING TWO BRACKETED PARAGRAPHS ARE TO BE DELETED IF BOND IS NOT BOOK ENTRY ONLY: 

 [Unless this Bond is presented by an authorized representative of The Depository Trust Company, a New York corporation (“DTC”)
to the Issuer or its agent for registration of transfer, exchange, or payment, and any Bond issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized representative of DTC (and any payment is made
to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof,
Cede & Co., has an interest herein. 
 As provided in the Indenture referred to herein, until the termination of the system

 The CALIFORNIA STATEWIDE COMMUNITIES DEVELOPMENT AUTHORITY, a public entity of the State of California
(the “Issuer”), for value received, hereby promises to pay (but only out of the sources hereinafter mentioned) to the Registered Owner set forth above, or registered assigns, on the Maturity Date, unless this Bond shall have been called
for redemption in whole or in part, upon surrender hereof, the Principal Amount set forth above and to pay (but only out of the sources hereinafter mentioned) to the Registered Owner, or registered assigns, interest thereon at the rate set forth
above calculated on the basis of a 360-day year of twelve 30-day months from the most recent Interest Payment Date (hereinafter defined) to which interest has been paid or duly provided for, or from the date of authentication hereof if such date is
on an Interest Payment Date to which interest has been paid or duly provided for, or from the Issue Date specified above if no interest has been paid or duly provided for, such payments of interest to be made on each Interest Payment Date until the
principal or redemption price hereof has been paid or duly provided for as aforesaid. The principal or redemption price of this Bond (or of a portion of this Bond, in the case of a partial redemption) is payable to the Registered Owner hereof in
immediately available funds upon presentation and surrender hereof at the principal corporate trust office of the Trustee (hereinafter defined) or its successor, as paying agent (the “Paying Agent”), under the Trust Indenture dated as of
August 1, 2008 (the “Indenture”) by and between the Issuer and Wells Fargo Bank, National Association, or its successor, as trustee (the “Trustee”) securing the series of Bonds of which this Bond is one. CAPITALIZED TERMS
NOT OTHERWISE DEFINED HEREIN SHALL HAVE THE MEANINGS SPECIFIED THEREFOR IN THE INDENTURE. All payments of interest on Bonds shall be paid to the Registered Owner hereof whose name appears in the Bond Register kept by the Bond Registrar as of the
close of business on the applicable Regular or Special Record Dates in immediately available funds by wire transfer to a bank within the continental United States or deposited to a designated account if such account is maintained with the Paying
Agent as directed by the Registered Owner in writing or as otherwise directed in writing by the Registered Owner at least five Business Days prior to each Interest Payment Date. The Regular Record Date for any Interest Payment Date shall be the
close of business on the 15th day (whether or not a Business Day) of the calendar month immediately preceding such Interest Payment Date. Any interest on any Bond which is payable, but is not punctually paid or provided for, on any Interest Payment
Date and within any applicable grace period (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Registered Owner hereof on the relevant Regular Record Date by virtue of having been such Registered Owner, and
such Defaulted Interest shall be paid to the person in whose name this Bond is registered at the close of business on a Special Record Date to be fixed by the Trustee, such date to be no more than 15 nor fewer than 10 days prior to the date of
proposed payment. This Bond is registered as to both principal and interest in the Bond Register kept by the Bond Registrar and may be transferred or exchanged, subject to the further conditions specified in the Indenture, only upon surrender hereof
at the office of the Bond Registrar. This Bond is payable solely from the sources hereinafter mentioned. 
 THE BONDS DO NOT CONSTITUTE A
DEBT OR LIABILITY OF THE STATE OF CALIFORNIA OR OF ANY POLITICAL SUBDIVISION THEREOF, OTHER THAN THE AUTHORITY, BUT SHALL BE PAYABLE SOLELY FROM THE FUNDS PROVIDED THEREFOR. THE AUTHORITY SHALL NOT BE OBLIGATED TO PAY THE PRINCIPAL OF THE BONDS, OR
THE REDEMPTION PREMIUM OR INTEREST THEREON, EXCEPT FROM THE FUNDS PROVIDED UNDER THE INDENTURE AND THE AGREEMENT 

  

 A-2 

 
AND NEITHER THE FAITH AND CREDIT NOR THE TAXING POWER OF THE STATE OF CALIFORNIA OR OF ANY POLITICAL SUBDIVISION THEREOF, INCLUDING THE AUTHORITY, IS PLEDGED
TO THE PAYMENT OF THE PRINCIPAL OF OR THE REDEMPTION PREMIUM OR INTEREST ON THE BONDS. THE ISSUANCE OF THE BONDS SHALL NOT DIRECTLY OR INDIRECTLY OR CONTINGENTLY OBLIGATE THE STATE OF CALIFORNIA OR ANY POLITICAL SUBDIVISION THEREOF TO LEVY OR TO
PLEDGE ANY FORM OF TAXATION OR TO MAKE ANY APPROPRIATION FOR THEIR PAYMENT. THE AUTHORITY HAS NO TAXING POWER. 
 This Bond is one of a duly
authorized issue of revenue bonds of the Issuer issued in the aggregate principal amount of $                     designated “California
Statewide Communities Development Authority Environmental Facilities Revenue Bonds (Microgy Holdings Project) Series 2008_” (the “Bonds”) issued under the Indenture. The Bonds are being issued by the Issuer for the purpose of
financing a portion of the costs of acquiring, constructing and improving certain solid waste disposal facilities (each a “Facility,” and, collectively, the “Project”). The Issuer will loan the proceeds of the Bonds to Microgy
Holdings, LLC (the “Company”) pursuant to the provisions of a Loan Agreement, dated as of August 1, 2008 (the “Agreement”), between the Issuer and the Company. 
 The Bonds are payable solely from and secured by a pledge of the Trust Estate, which includes, among other things, (i) all of the right, title and
interest of the Issuer in and to the Revenues, including, without limitation, “Loan Payments” made by the Company pursuant to the Agreement, payments received by the Trustee pursuant to a Guarantee Agreement, dated as of October 1,
2006, as supplemented and amended by a Supplemental Guarantee Agreement, dated as of August 1, 2008 (as so supplemented and amended, the “Guarantee”), from the Company and Microgy Hanford LLC, Microgy Riverdale LLC, MST Production
Ltd., MST GP, LLC, MST Estates, LLC, Rio Leche Estates, L.L.C., Mission Biogas, L.L.C., and Hereford Biogas, L.L.C. (the “Subsidiary Guarantors”) to the Trustee, and from payments received by the Trustee pursuant to a Collateral Trust
Agreement, dated as of October 1, 2006, as previously supplemented and amended, among Wells Fargo Bank, National Association, as collateral trustee, the Company, and the Subsidiary Guarantors, (ii) the Agreement and all right, title and
interest of the Issuer under and pursuant to the Agreement, insofar as they relate to all the Bonds issued and outstanding under the Indenture (except for the indemnification and expense reimbursement rights and other rights contained in the
Agreement and any rights of the Issuer to receive notices, certificates, requests, requisitions, directions and other communications under the Agreement), including, without limitation, all payments to be received under and pursuant to and subject
to the provisions of the Agreement, and (iii) all amounts on deposit in the Bond Fund, the Construction Fund, the Debt Service Reserve Fund, or other funds created under the Indenture (other than the Rebate Fund). Except as otherwise specified
in the Indenture, this Bond is entitled to the benefits of the Indenture equally and ratably both as to principal (redemption price, including redemption premium) and interest with all other Bonds issued under the Indenture, to which reference is
made for a description of the rights of the owners of the Bonds; the rights and obligations of the Issuer; the rights, duties and obligations of the Trustee; and the provisions relating to amendments to and modifications of the Indenture, to all of
which the Registered Owner of this Bond assents by acceptance of this Bond. Reference is also hereby made to the Agreement for the provisions, among others, with respect to the nature and extent of the rights, duties and obligations thereunder of
the Issuer, the Trustee and the Company and the modification or amendment of the Agreement.

 FOR SO LONG AS THIS BOND IS HELD IN BOOK-ENTRY FORM REGISTERED IN THE NAME OF CEDE & CO. ON THE
REGISTRATION BOOKS OF THE ISSUER KEPT BY THE TRUSTEE, AS BOND REGISTRAR, THIS BOND, IF CALLED FOR PARTIAL REDEMPTION IN ACCORDANCE WITH THE INDENTURE, SHALL BECOME DUE AND PAYABLE ON THE REDEMPTION DATE DESIGNATED IN THE NOTICE OF REDEMPTION GIVEN
IN ACCORDANCE WITH THE INDENTURE AT, AND ONLY TO THE EXTENT OF, THE REDEMPTION PRICE, PLUS ACCRUED INTEREST TO THE SPECIFIED REDEMPTION DATE; AND THIS BOND SHALL BE PAID, TO THE EXTENT SO REDEEMED, (i) UPON PRESENTATION AND SURRENDER THEREOF AT
THE OFFICE SPECIFIED IN SUCH NOTICE OR (ii) AT THE WRITTEN REQUEST OF CEDE & CO., BY CHECK OR DRAFT MAILED TO CEDE & CO. BY THE TRUSTEE OR BY WIRE TRANSFER TO CEDE & CO. BY THE TRUSTEE IF CEDE & CO. AS
BONDOWNER SO ELECTS. IF, ON THE REDEMPTION DATE, MONEYS FOR THE REDEMPTION OF BONDS TO BE REDEEMED, TOGETHER WITH INTEREST TO THE REDEMPTION DATE, SHALL BE HELD BY THE TRUSTEE SO AS TO BE AVAILABLE THEREFOR ON SUCH DATE, AND AFTER NOTICE OF
REDEMPTION SHALL HAVE BEEN GIVEN IN ACCORDANCE WITH THE INDENTURE, THEN, FROM AND AFTER THE REDEMPTION DATE, THE AGGREGATE PRINCIPAL AMOUNT OF THIS BOND SHALL BE IMMEDIATELY REDUCED BY AN AMOUNT EQUAL TO THE AGGREGATE PRINCIPAL AMOUNT THEREOF SO
REDEEMED, NOTWITHSTANDING WHETHER THIS BOND HAS BEEN SURRENDERED TO THE TRUSTEE FOR CANCELLATION. 
 If an Event of Default occurs, the
principal of all Bonds issued under the Indenture may become due and payable upon the conditions and in the manner and with the effect provided in the Indenture. 
 No recourse shall be had for the payment of the principal of, redemption premium, if any, or interest on this Bond, or for any claim based hereon or on the Indenture, against any member, officer or employee, past,
present or future, of the Issuer or of any successor body, as such, either directly or through the Issuer or any such successor body, under any constitutional provision, statute or rule of law, or by the enforcement of any assessment or by any legal
or equitable proceeding or otherwise.

 The principal amount of the Bonds so required to be redeemed on
any such mandatory redemption date shall be reduced by the principal amount of any Bonds which, at least 45 days prior such redemption date, (1) shall have been acquired by the Trustee at the written direction of the Company, at a price not
exceeding the principal amount of such Bonds plus accrued interest to the date of purchase thereof and delivered to the Trustee for cancellation, or (2) shall have been redeemed pursuant to any other redemption provision herein and not
previously so credited. 
 Extraordinary Mandatory Redemption 
 (i) Taxability. The Bonds shall be subject to mandatory redemption, at a redemption price equal to 106% of the principal amount
being redeemed plus accrued interest to the redemption date on any date on or after the one hundred eightieth day (or such earlier date as may be designated by the Company) after a final determination by a 

  

 A-5 

 
court of competent jurisdiction or an administrative agency (including the Internal Revenue Service), or receipt by the Company of an opinion of Bond Counsel
obtained by the Company, to the effect that the interest payable on the Bonds is or will be included in the gross income of the owners thereof for federal income tax purposes, other than any Owner who is a “substantial user” of the Project
or a “related person” within the meaning of Section 147(a) of the Code. Subject to the foregoing provisions, the Bonds shall be redeemed in whole unless, in the opinion of Bond Counsel mutually acceptable to the Issuer, the Trustee
and the Company, the redemption of a portion of such Bonds would have the result that interest payable on the Bonds remaining outstanding after such redemption would not be includable in the gross income for federal income tax purposes of any owner
of any such Bonds. Any such partial redemption shall be in such amount as is necessary to accomplish such result; and 
 (ii)
Excess Proceeds. The Bonds shall be subject to mandatory redemption, in part, on any date, to the extent that proceeds of the Bonds are transferred to the Bond Fund pursuant to Section 5.3 or 5.4 of the Indenture, at a redemption price
equal to the principal amount being redeemed plus accrued interest to the redemption date. 
 Extraordinary Optional Redemption 
 The Bonds shall be subject to optional redemption by the Issuer, at the written direction of the Company, in whole or in part as described below, on any
date, at a redemption price equal to the principal amount being redeemed plus accrued interest to the redemption date, if: 
 (i) the Company shall have determined that the continued construction or operation of a Facility is impracticable, uneconomical or undesirable due to (A) the imposition of taxes, other than ad valorem taxes currently levied upon
privately owned property used for the same general purpose as such Facility, or other liabilities or burdens with respect to such Facility or the operation thereof, (B) changes in technology, in environmental standards or legal requirements or
in the economic availability of materials, supplies, equipment or labor or (C) destruction of or damage to all or part of such Facility; 
 (ii) all or substantially all of a Facility shall have been condemned or taken by eminent domain; 
 (iii) the construction or operation of a Facility shall have been enjoined or shall have otherwise been prohibited by any order, decree, rule or regulation of any court or of any federal, state or local regulatory body, administrative
agency or other governmental body; or 
 (iv) a Facility or portion thereof shall have been sold and the proceeds of sale
shall not have been reinvested as provided in the Guarantee. 
 Anything above to the contrary notwithstanding, if any of the events
described above shall have occurred with respect to a portion, but not all, of the Project, the amounts of Bonds that may be redeemed shall not exceed an amount derived by multiplying the total principal amount of the Bonds by a fraction
(a) the numerator of which is the cost of the Project or portion thereof so affected and (b) the denominator of which is the total cost of the Project.

 The Company shall deliver notice to the Trustee of its intention to prepay the principal of, redemption
premium, if any, and interest on the Bonds and cause the Bonds to be called for optional redemption at least ten (10) Business Days prior to the date the Trustee gives notice to the Registered Owners of the Bonds of the proposed redemption of
the Bonds. The Trustee shall cause notice of any redemption of Bonds under the Indenture, which notice shall be prepared by the Company, to be mailed by first class mail, postage prepaid (except when DTC is the Registered Owner of all of the Bonds
and except for any person or entity owning or providing evidence of ownership satisfactory to the Trustee of a legal or beneficial ownership in at least $1,000,000 of principal amount of Bonds who so requests, in which cases, by certified mail,
return receipt requested), to the Registered Owners of all Bonds to be redeemed at the registered addresses appearing in the Bond Register kept for such purpose pursuant to Article II of the Indenture. Each such notice shall (i) be mailed at
least 30 days prior to the redemption date for the Bonds, (ii) identify the Bonds to be redeemed if less than all Bonds are to be redeemed (specifying the CUSIP numbers, if any, assigned to the Bonds), (iii) specify the redemption date and
the redemption price, (iv) state whether the notice is conditional or not as permitted by the Indenture, and (v) state that on the redemption date the Bonds called for redemption will be payable at the office of the Trustee designated in
such notice, that from that date interest will cease to accrue and that no representation is made as to the accuracy or correctness of the CUSIP numbers printed therein or on the Bonds; provided, however, that so long as DTC or its nominee is the
sole Registered Owner of the Bonds under the Book-Entry Only System, redemption notices will be sent to Cede & Co. Any failure on the part of DTC, a direct participant or indirect participant to give such notice to the Owner or any defect
therein shall not affect the sufficiency or validity of any proceedings for the redemption of the Bonds. No defect affecting any Bond, whether in the notice of redemption or mailing thereof (including any failure to mail such notice), shall affect
the validity of the redemption proceedings for any other Bonds. 
 Selection of Bonds for Redemption 
 Except as otherwise provided in the Indenture, the particular Bonds to be called for redemption shall be selected by the Trustee by lot or any other
customary random method determined by the Trustee to be fair and reasonable provided that a portion of a Bond may be redeemed only in Authorized Denominations. 
 Transfer of Bonds 
 This Bond is transferable by the Registered Owner hereof at the designated office of the Bond Registrar,
upon surrender of this Bond, accompanied by a duly executed instrument of transfer in form and with guaranty of signature satisfactory to the Bond Registrar, subject to such reasonable regulations as the Issuer or the Bond Registrar may prescribe,
and upon payment of any tax or other governmental charge incident to such transfer. Upon any such transfer, a new Bond or Bonds in the same aggregate principal amount will be issued to the transferee. Except as set forth in this Bond and as
otherwise provided in the Indenture, the person in whose name this Bond is registered shall be deemed the owner hereof for all purposes, and the Issuer, any Paying Agent, the Bond Registrar, the Authenticating Agent and the Trustee shall not be
affected by any notice to the contrary. 
  

 A-7 

 This Bond shall not be valid or become obligatory for any purpose or be entitled to any security or
benefit under the Indenture until either (i) the Certificate of Authentication hereon shall have been signed by the Trustee as Bond Registrar, or any successor, or (ii) a manually signed Comptroller’s Registration Certificate has been
attached hereto or endorsed hereon. 
 It is hereby certified, recited and declared that all acts, conditions and things required to exist,
happen and be performed precedent to and in the execution and delivery of the Indenture and the issuance of this Bond do exist, have happened and have been performed in due time, form and manner as required by law; and that the issuance of this Bond
and the issue of which it forms a part, together with all other obligations of the Issuer, does not exceed or violate any constitutional or statutory limitation. 
 IN WITNESS WHEREOF, the Issuer has caused this Bond to be executed in its name by the manual or facsimile signature of its President and attested by the manual or facsimile signature of the Secretary, all as of the
date first above written.
