preceding a Business Day or the Maturity Date, as the 

  

 18 







 
Remarketing Agent shall determine in accordance with the provisions of this Section. A Flexible Rate Bond can have an Interest Period, and bear interest at a
Flexible Rate, different than another Flexible Rate Bond. In making the determinations with respect to Interest Periods, subject to limitations imposed by the second preceding sentence and in Section 2.4 hereof, on each Rate Determination Date
for a Flexible Rate Bond, the Remarketing Agent shall select for such Bond the Interest Period which would result in the Remarketing Agent being able to remarket such Bond at par in the secondary market at the lowest average interest cost for all
Flexible Rate Bonds; provided, however, that if the Remarketing Agent has received notice from the Company that the Bonds are to be changed from the Flexible Mode to any other Mode, the Remarketing Agent shall select Interest Periods which do not
extend beyond the day preceding the resulting applicable Mandatory Purchase Date of the Bonds. 
 Except while the Bonds are registered in a
Book-Entry System, in order to receive payment of the Purchase Price the Owner of any Bond in the Flexible Mode must present such Bond to the Paying Agent, by 12:00 noon on the Rate Determination Date, in which case, the Paying Agent shall pay the
Purchase Price to such Owner by 3:00 P.M. on the same day.

respect to each Bond in the Flexible Mode which is subject to adjustment on such date, shall determine the Flexible Rate(s) for the Interest Periods then selected for such Bond and shall give notice by Electronic Means to the Paying Agent and the
Company, of the Interest Periods, the Purchase Date(s) and the Flexible Rate(s). The Remarketing Agent shall make the Flexible Rate and Interest Period available after 2:00 P.M. on each Rate Determination Date by telephone or Electronic Means to any
Beneficial Owner or Notice Party requesting such information. 
 Section 2.6. Determination of Interest
Rates During the Daily Mode and the Weekly Mode. The interest rate for the Bonds in the Daily Mode or Weekly Mode shall be the rate of interest per annum determined by the Remarketing
Agent on and as of the applicable Rate Determination Date as the minimum rate of interest which, in the opinion of the Remarketing Agent under then-existing market conditions, would result in the sale of the Bonds in the Daily Rate Period or Weekly
Rate Period, as applicable, at a price equal to the principal amount thereof, plus interest, if any, accrued through the Rate Determination Date during the then current Interest Accrual Period. 
 (a) During the Daily Mode, the Remarketing Agent shall establish the Daily Rate by 10:00 A.M. on each Rate Determination Date. The Daily Rate for any day
during the Daily Mode which is not a Business Day shall be the Daily Rate established on the immediately preceding Rate Determination Date. The Remarketing Agent shall make the Daily Rate available no less frequently than once each week by telephone

telephone or Electronic Means to any Beneficial Owner or Notice Party requesting such rate.

of Term Rates and Fixed Rates. (a) Term Rates. Except as provided in Section 2.8 hereof, once the Bonds are changed to the Term Rate Mode, the Bonds shall continue in the Term Rate
Mode until changed to another Mode in accordance with Section 2.9 hereof. The Term Rate shall be determined by the Remarketing Agent not later than 4:00 P.M. on the Rate Determination Date, and the Remarketing Agent shall make the Term Rate
available by telephone or by Electronic Means to any Notice Party requesting such rate. The Term Rate shall be the minimum rate which, in the sole judgment of the Remarketing Agent, would result in a sale of the Bonds at a price equal to the
principal amount thereof on the Rate Determination Date for the Interest Period selected by the Company in writing delivered to the Remarketing Agent before such Rate Determination Date. If a new Interest Period is not selected by the Company prior
to a Rate Determination Date, the new Interest Period shall be the same length as the current Interest Period (or such lesser period as shall be necessary to comply with the last sentence of this paragraph). The Remarketing Agent shall make the Term
Rate available by telephone or Electronic Means after 5:00 P.M. on the Rate Determination Date to any Notice Party requesting such Term Rate. Upon request of any Notice Party the Paying Agent shall give notice of such rate by Electronic Means. No
Interest Period in the Term Rate Mode may extend beyond the applicable Maturity Date. 
 (b) Fixed Rates. The Remarketing Agent
shall determine the Fixed Rate for the Bonds being converted to the Fixed Rate Mode in the manner and at the times as follows: not later than 4:00 P.M. on the applicable Rate Determination Date, the Remarketing Agent shall determine the Fixed Rate
(or Rates, if the Bonds will have Serial Maturity Dates in accordance with Section 2.9(b)(v) hereof). Except as set forth in Section 2.9(b)(v) hereof, the Fixed Rate shall be the minimum interest rate which, in the sole judgment of the
Remarketing Agent, will result in a sale of the Bonds at a price equal to the principal amount thereof on the Rate Determination Date. The Remarketing Agent shall make the Fixed Rate available by telephone or by Electronic Means after 5:00 P.M. on
the Rate Determination Date to any Notice Party requesting such Fixed Rate. Upon request of any Notice Party the Paying Agent shall give notice of such rate by Electronic Means. Subject to Section 2.9(b)(v), the Fixed Rate so established shall
remain in effect until the Maturity Date of such Bonds. 
 Section 2.8. Alternate Rates. The following provisions
shall apply in the event (i) the Remarketing Agent fails or is unable to determine the interest rate or Interest Period for the Bonds, (ii) the method by which the Remarketing Agent determines the interest rate or Interest Period with
respect to the Bonds (or the selection by the Company of the Interest Periods for Bonds in the Term Rate Mode) shall be held to be unenforceable by a court of law of competent jurisdiction or (iii) if the Remarketing Agent suspends its
remarketing effort in accordance with the Remarketing Agreement. These provisions shall continue to apply until such time as the Remarketing Agent (or the Company if applicable) again makes such determinations. In the 

  

 20 







 
case of clause (ii) above, the Remarketing Agent (or the Company, if applicable) shall again make such determination at such time as there is delivered
to the Remarketing Agent and the Company an opinion of Bond Counsel to the effect that there are no longer any legal prohibitions against such determinations. The following shall be the methods by which the interest rates and, in the case of the
Flexible and Term Rate Modes, the Interest Periods, shall be determined for the Bonds as to which any of the events described in clauses (i), (ii) or (iii) shall be applicable. Such methods shall be applicable from and after the date any
of the events described in clauses (i), (ii) or (iii) first become applicable to the Bonds until such time as the events described in clauses (i), (ii) or (iii) are no longer applicable to the Bonds. These provisions shall not
apply if the Company fails to select an Interest Period for the Bonds in the Term Rate Mode for a reason other than as described in clause (ii) above. 
 (a) For Flexible Rate Bonds, the next Interest Period shall be from, and including, the first day following the last day of the current Interest Period for the Bonds to, but excluding, the next succeeding Business Day
and thereafter shall commence on each Business Day and extend to, but exclude, the next succeeding Business Day. For each such Interest Period, the interest rate for the Bonds shall be the applicable Alternate Rate in effect on the Business Day that
begins an Interest Period. 
 (b) If the Bonds are in the Daily Mode or the Weekly Mode, then the Bonds shall bear interest during each
subsequent Interest Period at the Alternate Rate in effect on the first day of such Interest Period. 
 (c) If the Bonds are then in the Term
Rate Mode, then the Bonds shall automatically convert to Flexible Rate Bonds, with an Interest Period commencing on the first day following the last day of the current Interest Period for the Bonds to, but excluding, the next succeeding Business Day
and thereafter shall commence on each Business Day and extend to, but exclude, the next succeeding Business Day. For each such Interest Period, the interest rate for the Bonds shall be the applicable Alternate Rate in effect at the beginning of each
such Interest Period. 
 Section 2.9. Changes in Mode. Subject to the provisions of this Section, the
Company may effect a change in Mode with respect to all (but not less than all) of the Bonds by following the procedures set forth in this Section. If a change in Mode will make the Bonds subject to Rule 15c2-12 promulgated under the Securities Act
of 1934, as amended, it shall be a condition to the conversion that the Company shall have executed a continuing disclosure undertaking satisfying the requirements of such Rule and shall cooperate with the Remarketing Agent and any Underwriter (as
defined in such Rule) in satisfying the requirements of such Rule. 
  

 21 







 (a) Changes to Modes Other Than to Fixed Rate
Mode. All of the Bonds (other than Bonds in the Fixed Rate Mode) may be changed from one Mode to another Mode (other than the Fixed Rate Mode) as follows: 
 (i) Mode Change Notice; Notice to Owners. No later than a Business Day which is at least thirty (30) days (or such shorter time as may be agreed to by the Issuer, the
Company, the Trustee, the Tender Agent and the Remarketing Agent) preceding the proposed Mode Change Date, the Company shall give written notice to the Notice Parties of its intention to effect a change in the Mode from the Mode then prevailing (for
purposes of this Section, the “Current Mode”) to another Mode (for purposes of this Section, the “New Mode”) specified in such written notice, and, if the change is to a Term Rate Mode, the length of the initial Interest Period
as set by the Company. Such notice to the Notice Parties shall also include the identity of the provider of the Liquidity Facility and/or Credit Enhancement. Notice of the proposed change in Mode shall be given by the Tender Agent to the Owners of
the Bonds not less than the 15th day next preceding the Mode Change Date provided that no notice need be given for a Mode Change Date occurring on the first Business Day following the last day of a Flexible Rate Period or Term Rate Mode or on a
Substitution Date. Such notice shall state: (1) the Mode to which the conversion will be made and the Mode Change Date; (2) except in the case of a change from the Daily Mode to the Weekly Mode or from the Weekly Mode to the Daily Mode,
that the Bonds will be subject to mandatory purchase on the Mode Change Date and the Purchase Price of the Bonds; and (3) if the Book-Entry System is no longer in effect, information with respect to required delivery of Bond certificates and
payment of Purchase Price. 
 (ii) Determination of Interest Rates. The New Mode shall commence on the Mode
Change Date and the interest rate(s) (together, in the case of a change to the Flexible Mode, with the Interest Period(s)) shall be determined by the Remarketing Agent (or the Company in the case of the Interest Period for the Bonds converted to the
Term Rate Mode) in the manner provided in Sections 2.5, 2.6 and 2.7 hereof, as applicable. 
 (iii) Conditions Precedent:

 (A) The Mode Change Date shall be: 
 (1) in the case of a change from the Flexible Mode, the next Mandatory Purchase Date for all of the Flexible Rate Bonds; 
 (2) in the case of a change from the Daily or Weekly Mode, any Business Day; and 
 (3) in the
case of a change from the Term Rate Mode to another Mode, or from a Term Rate Period to a Term Rate Period of a different duration, the Mode Change Date shall be limited to any Interest Payment Date on which the Bonds are subject to optional
redemption or to the last Interest Payment Date of the current Term Rate Period, as the case may be. Such Bonds shall be purchased on such Mode Change Date at a Purchase Price equal to 100% of the principal amount thereof, provided that if such
Bonds are to be purchased on an Interest Payment Date other than the last Interest Payment Date and would otherwise be 

  

 22 







 
subject to optional redemption on such Mode Change Date at a Redemption Price of more than 100% of the principal amount thereof, such Bonds shall be
purchased at a Purchase Price equal to such Redemption Price. 
 (B) If the Bonds to be converted are in the Flexible Mode, no Interest
Period set after delivery by the Company to the Remarketing Agent of the notice of the intention to effect a change in Mode shall extend beyond the day preceding the proposed Mode Change Date. 
 (C) The following items shall have been delivered to the Trustee, the Paying Agent and the Remarketing Agent on or prior to the Mode Change Date:

 (1) in the case of a change from a Short-Term Mode to a Long-Term Mode or from a Long-Term Mode to a Short-Term Mode, a
Favorable Opinion of Bond Counsel dated the Mode Change Date and addressed to the Notice Parties; 
 (2) if there is to be an
Alternate Liquidity Facility or an Alternate Credit Enhancement delivered in connection with such change, the items required by Section 4.8(d) hereof; and 
 (3) a Rating Confirmation Notice, or if the Mode Change Date is a Mandatory Purchase Date, a notice from the Rating Agencies of the
rating(s), if any, to be assigned the Bonds on such Mode Change Date. 
 (b) Change to Fixed Rate Mode. At
the option of the Company, all of the Bonds bearing interest at a Daily Rate, a Weekly Rate, a Term Rate or a Flexible Rate (in an amount which is an Authorized Denomination for the new Rate Period ) may be changed to the Fixed Rate Mode, as
provided in this Section 2.9(d). On any Business Day which is at least thirty (30) days (or such shorter time as may be agreed to by the Issuer, the Company, the Trustee and the Remarketing Agent, but in any event not less than the 15th
day next preceding the Mode Change Date) before the proposed Mode Change Date, the Company shall give written notice to the Notice Parties stating that the Mode will be changed to the Fixed Rate Mode and setting forth the proposed Mode Change Date.
Such notice shall also state whether or not there shall be Credit Enhancement with respect to the Bonds following such change and, if so, the identity of the Credit Provider. In addition, such notice shall state whether some or all of the Bonds to
be converted shall be converted to Serial Bonds and, if so, the applicable Serial Maturity Dates and Serial Payments, all as determined pursuant to subsection (v) of this subsection (b). Any such change in Mode shall be made as follows:

 (i) Mode Change Date. The Mode Change Date shall be: 
 (A) in the case of a change from the Flexible Mode, the next Mandatory Purchase Date for the Flexible Rate Bonds; 
  

 23 







 (B) in the case of a change from the Daily or Weekly Mode, any Business Day; and 
 (C) in the case of a change from the Term Rate Mode, the Mode Change Date shall be limited to any Interest Payment Date on which the Bonds are subject to
optional redemption or to the next Mandatory Purchase Date for the Term Rate Bonds, as the case may be. Such Bonds shall be purchased on such Mode Change Date at a Purchase Price equal to 100% of the principal amount thereof, provided that if such
Bonds would otherwise be subject to optional redemption on such Mode Change Date at a Redemption Price of more than 100% of the principal amount thereof, such Bonds shall be purchased at a Purchase Price equal to such Redemption Price. 

(ii) Notice to Owners. Not less than the 15th day next preceding the Mode Change Date, the Paying Agent shall mail, in the name
of the Company, a notice of such proposed change to the Owners of the Bonds stating that the Mode will be changed to the Fixed Rate Mode, the proposed Mode Change Date and that such Owner is required to tender such Owner’s Bonds for purchase on
such proposed Mode Change Date regardless of whether all of the conditions to the change to the Fixed Rate Mode are satisfied. 
 (iii)
General Provisions Applying to Change to Fixed Rate Mode. The change to the Fixed Rate Mode shall not occur unless the following items shall have been delivered to the Issuer, the
Company, the Trustee, the Credit Provider, if any, and the Remarketing Agent on or prior to the Mode Change Date: 
 (A) a Favorable Opinion
of Bond Counsel dated the Mode Change Date and addressed to the Issuer, the Company, the Trustee and the Remarketing Agent; 
 (B) if there
is to be Credit Enhancement delivered in connection with such change, the items required by Section 4.8(d) hereof in connection with the delivery of an Alternate Credit Enhancement; and 
 (C) notice from the Rating Agencies of the rating(s), if any, to be assigned the Bonds on such Mode Change Date. 
 (iv) Determination of Interest Rate. The Fixed Rate (or rates in the case of Serial Bonds) for the Bonds to be converted to
the Fixed Rate Mode shall be established by the Remarketing Agent on the Rate Determination Date applicable thereto pursuant to the provisions of Section 2.7(b). Such Rate shall remain in effect until the Maturity Date of the Bonds. 

Such determination shall be conclusive and binding upon the Issuer, the Company, the Trustee, the Credit Provider, if any, and the Owners of the Bonds
to which such rate will be applicable. Not later than 5:00 P.M., New York City time, on the date of determination of the Fixed Rate, the Remarketing Agent shall notify the Trustee, the Credit Provider, the Issuer and the Company of such rate by
telephone. 
  

 24 







 (v) Serialization and Sinking Fund; Price. Upon conversion of the
Bonds to the Fixed Rate Mode, the Bonds shall be remarketed at par, shall mature on the same Maturity Date(s) and be subject to the same mandatory sinking fund redemption, if any, and optional redemption provisions as set forth in this Indenture for
any prior Mode; provided, however, that if the Company shall deliver to the Trustee a Favorable Opinion of Bond Counsel, the Company may elect to (1) have some of the Bonds be Serial Bonds and some subject to sinking fund redemption even if
such Bonds were not Serial Bonds or subject to mandatory sinking fund redemption prior to such change, (2) change the optional redemption dates and/or premiums set forth in Section 3.3(b) hereof, and/or (3) sell some or all of the
Bonds at a premium or a discount to par . 
 (c) Failure to Satisfy Conditions Precedent to
a Mode Change. In the event the conditions described above in subsections (a) or (b), as applicable, of this Section have not been satisfied by the applicable Mode Change Date, then the New Mode shall not take effect
(although any mandatory purchase shall be made on such date if notice has been sent to the Owners stating that such Bonds would be subject to mandatory purchase on such date). If the failed change in Mode was from the Flexible Mode, the Bonds shall
remain in the Flexible Mode with interest rates and Interest Periods to be established by the Remarketing Agent on the failed Mode Change Date in accordance with Section 2.5 hereof. If the failed change in Mode was from the Daily Mode, the
Bonds shall remain in the Daily Mode, and if the failed change in Mode was from the Weekly Mode, the Bonds shall remain in the Weekly Mode, in each case with interest rates established in accordance with the applicable provisions of Section 2.6
hereof on and as of the failed Mode Change Date. If the failed change in Mode was from the Term Rate Mode, then the Bonds shall stay in the Term Rate Mode for an Interest Period ending on the following Interest Payment Date for the Bonds in the Term
Rate Mode and the interest rate shall be established by the Remarketing Agent on the failed Mode Change Date in accordance with Section 2.7(a) hereof. 
 (d) Rescission of Election. Notwithstanding anything herein to the contrary, the Company may rescind any election by it to change a Mode as described above prior to the Mode Change Date by giving
written notice thereof to the Notice Parties prior to such Mode Change Date. If the Tender Agent receives notice of such rescission prior to the time the Tender Agent has given notice to the Owners of the Bonds, then such notice of change in Mode
shall be of no force and effect. If the Tender Agent receives notice from the Company of rescission of a Mode change after the Tender Agent has given notice thereof to the Owners of the Bonds, then if the proposed Mode Change Date would have been a
Mandatory Purchase Date, such date shall continue to be a Mandatory Purchase Date. If the proposed change in Mode was from the Flexible Mode, the Bonds shall remain in the Flexible Mode with interest rates and Interest Periods to be established by
the Remarketing Agent on the proposed Mode Change Date in accordance with Section 2.5 hereof. If the proposed change in Mode was from the Daily Mode, the Bonds shall remain in the Daily Mode, and if the proposed change in Mode was from the
Weekly Mode, the Bonds shall remain in the Weekly Mode, in each case with interest rates established in accordance with the applicable provisions of Section 2.6 hereof on and as of the 

  

 25 







 
proposed Mode Change Date. If the proposed change in Mode was from the Term Rate Mode, then the Bonds shall stay in the Term Rate Mode for an Interest Period
ending on the following Interest Payment Date for the Bonds in the Term Rate Mode and the interest rate shall be established by the Remarketing Agent on the proposed Mode Change Date in accordance with Section 2.7(a) hereof. If the Remarketing
Agent is unable to determine the interest rate on the proposed Mode Change Date, the provisions of Section 2.8 shall apply. 
 Section 2.10. Form. Bonds authenticated and delivered hereunder shall be in substantially the form set forth in Exhibit A attached hereto, with appropriate variations, omissions and insertions as permitted or required by
this Indenture. 
 Section 2.11. Payment. The principal of the Bonds shall be paid upon the presentation and surrender of
said Bonds at the principal corporate trust office of the Trustee. The interest on the Bonds shall be payable by check or draft drawn upon the Trustee and mailed to or, at the option of the Owners of Bonds in the aggregate principal amount of not
less than $1,000,000, transmitted by wire transfer to the Owners as of the close of business on the Record Date next preceding the Interest Payment Date at their respective addresses as such appear as of the close of business on such Record Date on
the bond registration books kept by the Trustee, or in connection with any wire transfer to the bank account number previously filed by the Owner with the Trustee for such purpose, except that if and to the extent that there shall be a default in
the payment of the interest due on such Interest Payment Date, such defaulted interest shall be paid to the Owners in whose name any such Bonds (or any Bond or Bonds issued upon transfer or exchange thereof) are registered at the close of business
on the fifth Business Day next preceding the date of payment of such defaulted interest. All payments shall be made in lawful money of the United States of America. 
 Section 2.12. Execution. The Bonds shall be executed on behalf of the Issuer by the manual or facsimile signatures of the Mayor and the Clerk and shall have impressed or imprinted thereon the
corporate seal of the Issuer. A facsimile signature shall have the same force and effect as if personally signed. In case any officer whose signature or facsimile of whose signature shall appear on the Bonds shall cease to be such officer before the
delivery of such Bonds, such signature or such facsimile shall nevertheless be valid and sufficient for all purposes, the same as if he had remained in office until delivery. 
 Section 2.13. Limited Obligation. The Bonds, together with interest thereon, shall be payable as hereinafter set forth, and
shall be a valid claim of the Owners thereof only against the Trust Estate, which Trust Estate is hereby pledged and mortgaged for the equal and ratable payment of the Bonds (principal and interest) and shall be used for no other purpose than to pay
the principal of and interest on the Bonds, and the Trustee’s fees, except as may be otherwise expressly authorized in this Indenture. The Bonds and interest thereon shall not constitute an indebtedness of the Issuer within the meaning of any
constitutional or statutory provision and shall never constitute an obligation or charge against the general credit or taxing powers of the Issuer. 
  

 26 







 Section 2.14. Authentication. Only such Bonds as shall have endorsed thereon a
certificate of authentication substantially in the forms set forth in Exhibits A and B attached hereto duly executed by the Trustee shall be entitled to any right or benefit under this Indenture. No Bond shall be valid and obligatory for any purpose
unless and until such certificate of authentication shall have been duly executed by the Trustee, and such certificate of the Trustee upon any such Bond shall be conclusive evidence that such Bond has been authenticated and delivered under this
Indenture. The Trustee’s certificate of authentication on any Bond shall be deemed to have been executed if signed by an authorized signatory of the Trustee, but it shall not be necessary that the same signatory sign the certificate of
authentication on all of the Bonds issued hereunder. 
 Section 2.15. Delivery of the Bonds. The
Issuer shall execute and deliver to the Trustee and the Trustee shall authenticate the Bonds and deliver said Bonds to the purchaser or purchasers thereof. Prior to the delivery or original issuance by the Trustee of any authenticated Bonds there
shall be or have been delivered to the Trustee: 
 (a) Original executed counterparts of this Indenture and the Loan Agreement. 

(b) A written order to the Trustee by the Issuer to authenticate and deliver the Bonds to the purchaser or purchasers thereof upon payment to the
Trustee, but for the account of the Issuer, of a sum specified in such order plus or less accrued interest thereon, if any, as the case may be, to the date of delivery. 
 (c) A copy, duly certified by the Clerk, of the proceedings of the City Council of the Issuer authorizing the issuance of the Bonds. 
 (d) An opinion of Bond Counsel to the effect that (i) the Bonds have been validly issued and are legally binding and enforceable under this Indenture, and (ii) the interest on the Bonds is excluded from
gross income for federal income tax purposes, except as set forth in such opinion. 
 Section 2.16. Mutilated,
Destroyed or Lost Bonds. In case any Bond issued hereunder shall become mutilated or be destroyed or lost, the Issuer shall, if not then prohibited by law, cause to be executed and the Trustee or the Trustee, as
appropriate, may authenticate and deliver a new Bond of like date, number, maturity and tenor in exchange and substitution for and upon cancellation of such mutilated Bond, or in lieu of and in substitution for such Bond destroyed or lost, upon the
holder’s paying the reasonable expenses and charges of the Issuer and the Trustee or the Trustee in connection therewith, and, in the case of a Bond destroyed or lost, his filing with the Trustee or the Trustee evidence satisfactory to it that
such Bonds were destroyed or lost, and of his ownership thereof, and furnishing the Issuer and Trustee or the Trustee with indemnity satisfactory to them. The Trustee is hereby authorized to authenticate any such new Bond. In the event any such
Bonds shall have matured or shall have been called for redemption prior to maturity, instead of issuing a new Bond, the Issuer may pay the same without the surrender thereof. 
  

 27 







 Section 2.17. Registration and Transfer of Bonds. The
Issuer hereby constitutes and appoints the Trustee as Registrar of the Issuer, and as Registrar the Trustee shall keep books for the registration and for the transfer of the Bonds as provided in this Indenture at the principal corporate trust office
of the Trustee. The person in whose name any Bond shall be registered shall be deemed and regarded as the absolute owner thereof for all purposes and payment of or on account of the principal of and interest on any such Bond shall be made only to or
upon the order of the registered owner thereof, or his legal representative, and neither the Issuer, the Trustee, nor the Bond Registrar shall be affected by any notice to the contrary but such registration may be changed as herein provided. All
such payments shall be valid and effectual to satisfy and discharge the liability upon such Bond to the extent of the sum or sums so paid. 
 Bonds may be transferred on the books of registration kept by the Registrar by the registered owner in person or by his duly authorized attorney, upon surrender thereof, together with a written instrument of transfer duly executed by the
registered owner or his duly authorized attorney. Upon surrender for transfer of any Bond at the principal corporate trust office of the Trustee, the Issuer shall execute and the Trustee shall authenticate and deliver in the name of the transferee
or transferees a new Bond or Bonds in the same aggregate principal amount, in the same Mode, and of any Authorized Denomination or Denominations. 
 Bonds may be exchanged at the principal corporate trust office of the Trustee for an equal aggregate principal amount of Bonds of any other Authorized Denomination or Denominations and in the same Mode. The Issuer shall execute and the
Trustee shall authenticate and deliver Bonds which the Bondholder making the exchange is entitled to receive, bearing numbers not contemporaneously then outstanding. The execution by the Issuer of any Bond of any denomination shall constitute full
and due authorization of such denomination and the Trustee shall thereby be authorized to authenticate and deliver such bond. 
 The Trustee
shall not be required to transfer or exchange any Bond during the period from and including a Record Date to the next succeeding Interest Payment Date of such Bond nor to transfer or exchange any Bond after the mailing of notice calling such Bond
for redemption has been made and prior to such redemption. 
 Such transfers of registration or exchanges of Bonds shall be without charge to
the Owners of such Bonds, but any taxes or other governmental charges required to be paid with respect to the same shall be paid by the Owner of the Bond requesting such transfer or exchange as a condition precedent to the exercise of such
privilege. 
 Section 2.18. Cancellation. All Bonds surrendered for the purpose of payment or retirement, or for exchange,
or for replacement or payment as provided above shall be canceled upon surrender thereof to the Trustee and, at the option of the Trustee, either cremated, shredded 

  

 28 







 
or otherwise disposed of. In the case of cremating, shredding or other disposition, the Trustee shall execute and forward to the Issuer an appropriate
certificate describing the Bonds involved and the manner of disposition. 
 Section 2.19. Temporary Bonds. Until
Bonds in definitive form are ready for delivery, the Issuer may execute, and upon the request of the Issuer the Trustee shall authenticate and deliver, subject to the provisions, limitations and conditions set forth herein, one or more Bonds in
temporary form, whether printed, typewritten, lithographed or otherwise produced, substantially in the form of the definitive Bonds, with appropriate omissions, variations and insertions, and in Authorized Denominations. Until exchanged for Bonds in
definitive form, such Bonds in temporary form shall be entitled to the lien and benefit of this Indenture. Upon the presentation and surrender of any Bond or Bonds in temporary form, the Issuer shall, without unreasonable delay, prepare, execute and
deliver to the Trustee and the Trustee shall authenticate and deliver, in exchange therefor, a Bond or Bonds in definitive form. Such exchange shall be made by the Trustee without making any charge therefor to the Owner of such Bond in temporary
form. 
 Section 2.20. Book-Entry System. (a) So long as the Bonds are in book-entry only form, the Trustee
shall comply with the terms of the DTC Representation Letter, the provisions of which are incorporated herein by this reference thereto with the same effect as if they were fully set forth herein. 
 (b) The book-entry system through the Securities Depository may be terminated upon the happening of any of the following: 
 (i) The Securities Depository or the Issuer, based upon advice from the Securities Depository, advise the Trustee that the Securities
Depository is no longer willing or able to properly discharge its responsibilities under the DTC Representation Letter and the Trustee or the Issuer are unable to locate a qualified successor clearing agency satisfactory to the Trustee and the
Issuer; or 
 (ii) The Issuer, in its sole discretion but with the prior written consent of the Trustee and the Company,
elects to terminate the book-entry system by notice to the Securities Depository, the Company, the Trustee, the Credit Provider and the Remarketing Agent; or 
 (iii) After the occurrence of an Event of Default (at which time the Trustee shall promptly notify each Beneficial Owner through the
Securities Depository of such Event of Default) the Beneficial Owners of a majority in aggregate outstanding principal amount of the Bonds, through the Participants and the Securities Depository, elect to discontinue the book-entry system through
the Securities Depository and so advise the Trustee, the Issuer, the Remarketing Agent, the Credit Provider and the Securities Depository in writing. 
  

 29 







 Upon the occurrence of any event hereinabove described, the Trustee shall notify all Beneficial Owners, through the
Securities Depository, and the Credit Provider of the occurrence of such event and of the availability of definitive or temporary certificated Bonds to Beneficial Owners requesting the same, in an aggregate outstanding principal amount representing
the ownership interest of each such Beneficial Owner, making such adjustments and allowances as it may find necessary or appropriate as to accrued interest and previous payments of principal and calls for redemption. Definitive certificated Bonds
shall be issued only upon surrender to the Trustee of the Bond held by the Securities Depository, accompanied by registration instructions for the definitive certificated Bonds. Neither the Issuer, the Remarketing Agent nor the Trustee shall be
liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon issuance of definitive certificated Bonds, all references herein to obligations imposed upon or to be
performed by the Securities Depository shall be deemed to be imposed upon and performed by the Trustee, to the extent applicable with respect to such definitive certificated Bonds. 
 (c) Whenever notice or other communication to the Bondholders is required by the Trustee under this Indenture, unless and until definitive certificated
Bonds shall have been issued and except as otherwise provided in this Indenture, the Trustee shall give all such notices and communications to the Securities Depository. The Trustee acknowledges that the Securities Depository has represented to the
Trustee in the DTC Representation Letter that the Securities Depository keeps and maintains records in its offices of the positions of Participants with respect to the Bonds. Whenever notice or other communication to the Beneficial Owners is
required by the Trustee under this Indenture, the Trustee shall not be required to give such notices and communications to any Beneficial Owner which has not designated an address to the Trustee pursuant to Section 16.2 hereof. 
 (d) Neither the Issuer, the Remarketing Agent, the Trustee nor any Paying Agent will have any responsibility or obligation to Participants, to indirect
Participants or to any Beneficial Owner with respect to (i) the accuracy of any records maintained by the Securities Depository, any Participant, or any indirect Participant; (ii) the payment by the Securities Depository, or any
Participant or indirect Participant of any amount with respect to the principal of, or premium, if any, or interest on the Bonds; (iii) any notice which is permitted or required to be given by Beneficial Owners under this Indenture;
(iv) the selection by the Securities Depository, or any direct or indirect Participant of any person to receive payment in the event of a partial redemption of the Bonds; or (v) any consent given or other action taken by the Securities
Depository as Bondholder.

Bonds in the Flexible Mode. Bonds in the Flexible Mode are not subject to optional redemption prior to their respective Purchase Dates. Bonds in the Flexible Mode shall be subject to redemption at the option of the

 Section 3.2. Optional Redemption of Bonds in the Daily Mode or the Weekly Mode. Bonds in the Daily Mode or the Weekly Mode are subject to

Fixed Rate Mode. (a) Bonds in a Term Rate Mode shall be subject to redemption, in whole or in part, on their individual Mandatory Purchase Dates, at the option of the Company at a redemption price equal to the principal
amount thereof. 
 (b) Bonds in the Term Rate Mode or Fixed Rate Mode are subject to redemption in whole on any date or in part on any
Interest Payment Date (and if in part, by lot or by such other method as the Trustee determines to be fair and reasonable) commencing on the Interest Payment Date next following the tenth anniversary of the change to the Term Rate Mode or Fixed Mode
at a redemption price of 100% of the principal amount of Bonds being redeemed, together with accrued interest, if any, to the redemption date. If the length of the Term Rate Period or Fixed Rate Period is less than ten years, then the Bonds shall
not be subject to redemption during such Term Rate Period or Fixed Rate Period. The foregoing provisions of this subsection (b) may be amended by the Issuer and the Trustee at the request of the Company prior to a conversion to a Long-Term Mode
upon delivery of a Favorable Opinion of Bond Counsel. 
 (c) The Company, in connection with a change to a Long-Term Mode, may waive or
otherwise alter its rights to direct the redemption of any such Bonds so changed to a Long-Term Mode at any time without premium; provided that notice describing the waiver or alteration shall be submitted to the Paying Agent, the Trustee and the
Remarketing Agent, together with a Favorable Opinion of Bond Counsel, addressed to them. 
 (d) If a Credit Enhancement is then in effect and
the Redemption Price includes any premium, the right of the Company to direct an optional redemption is subject to the condition that the Trustee has received, prior to the date on which notice of redemption is required to be given to Owners, either
Available Moneys of the Company or written confirmation from the Credit Provider that it can draw under the Credit Enhancement on the proposed redemption date in an aggregate amount sufficient to cover the principal of and premium and interest due
on the Redemption Date (it being understood that the Credit Enhancement provided upon the original issuance of the Bonds does not provide for the payment of such premium). 
  

 31 







 Section 3.4. Extraordinary Optional Redemption of Bonds
in the Term Rate or the Fixed Rate Mode. Bonds in the Term Rate Mode or the Fixed Rate Mode are subject to optional redemption by the Company, in whole but not in part, on any Business
Day, at a redemption price equal to the principal amount thereof, plus accrued interest, if any, to the Redemption Date, upon the occurrence of any of the following events: 
 (a) The Project or the Plant shall have been damaged or destroyed to such extent that the Company is thereby prevented, in the Company’s judgment,
from carrying on its normal operation thereof, or to such extent that it would not be economically feasible, in the Company’s judgment, for the Company to repair the Project or the Plant. 
 (b) All or substantially all of either the Project or the Plant shall have been condemned or taken by eminent domain. 
 (c) The construction or operation of either the Project or the Plant 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. 
 (d) The Company shall be required to redeem the Bonds, in whole or in part, pursuant to the provisions of the Reimbursement Agreement. 
 Section 3.5. Mandatory Redemption of Bonds Upon a Determination of Taxability. The Bonds shall be subject to special mandatory redemption in whole (or in part, if
such partial redemption will preserve the excludability from gross income for federal income tax purposes of interest on the Bonds remaining outstanding after such redemption, and if in part, by lot or by such other method as the Trustee determines
to be fair and reasonable) at any time at a Redemption Price equal to 100% of the principal amount thereof, without premium, plus interest accrued to (but excluding) the Redemption Date, if a “final determination” is made (A) that the
interest paid or payable on any Bond to other than a “substantial user” of the Project or a “related person” (within the meaning of Section 147(a) of the Code) (a “Substantial User”) is or was includable in the
gross income of the Owner thereof for federal income tax purposes as a result of the failure by the Company to observe or perform any covenant, condition or warranty on its part to be observed or performed under the Loan Agreement or the inaccuracy
of any representation or warranty by the Company under the Loan Agreement or by the Company in connection with the issuance of the Bonds, or (B) that interest on any Bond would be includable in the gross income of such Owner but for such
redemption. A “final determination” shall be deemed to have been made upon (1) the issuance of a published or private ruling or technical advice by the Internal Revenue Service, a settlement agreement between the Internal Revenue
Service and the Issuer (as approved by the Company) in connection with an audit of the Bonds, or a judicial 

  

 32 







 
decision in a proceeding by any court of competent jurisdiction in the United States (from which ruling, advice, settlement agreement or decision no further
right of appeal exists), in all cases in which the Company, at its expense, has participated or been a party or has been given the opportunity to contest the same or to participate or be a party, or (2) upon delivery of an opinion of Bond
Counsel obtained by the Company and delivered to the Trustee to the effect that interest on any Bond either is includable in gross income of any such Owner of such Bond (other than a Substantial User) or would be so includable but for such
redemption. Any special mandatory redemption shall be made not more than 180 days from the time of such final determination. Any special mandatory redemption of less than all of the Bonds shall be in such amounts and in such manner as the Trustee,
with the advice of Bond Counsel, shall deem proper. 
 If the Trustee receives written notice from any Owner or Beneficial Owner of any Bond
to the effect that (A) the Owner has been notified in writing by the Internal Revenue Service that it proposes to include the interest on any Bond in the gross income of such Owner, which the Trustee determines is for any of the reasons
described in this Section 3.5, or if any other proceeding has been instituted against such Owner which may lead to a final determination as described in this Section 3.5, and (B) such Owner will afford the Company the opportunity to
contest the same, either directly or in the name of the Owner, and until a conclusion of any appellate review, if sought, and the Trustee has received a copy of the notification described in clause (A) above, then the Trustee shall promptly
give notice thereof to the Company, the Issuer, the Credit Provider, and each Bondholder. The Trustee shall thereafter coordinate any similar requests or notices it may have received from other Owners and shall monitor the progress of any
administrative proceedings or litigation. If a final determination thereafter occurs, the Trustee shall make demand for prepayment in the appropriate amount from the Borrower under the Loan Agreement and give notice of the redemption of the
appropriate amount of Bonds, the redemption date to be no later than the date specified in this Section 3.5. In taking any action or making any determination under this subsection, the Trustee may rely on a Favorable Opinion of Bond Counsel.

 Section 3.6. Mandatory Redemption of Bonds From Balance in
Construction Fund. The Bonds shall be redeemed from moneys remaining in the Construction Fund on and after the Completion Date (as defined in the Loan Agreement), in whole or in part (and if in part, by lot or by such other method as
the Trustee determines to be fair and reasonable), at any time, at a redemption price equal to the principal amount being redeemed plus accrued interest to the redemption date. 
 Section 3.7. Notice. Notice of the call for any redemption, identifying the Bonds or portions thereof being called and the date on
which they shall be presented for payment, shall be given by the Trustee by first class mail, postage prepaid (except when DTC is the registered owner of all of the Bonds and except for persons or entities owning or providing evidence of ownership
satisfactory to the Trustee of a legal or beneficial ownership of at least $1,000,000 of principal amount of Bonds who so request, in which cases, by certified mail, return receipt requested), to the registered owners of all Bonds to be redeemed, at
the registered addresses 

  

 33 







 
appearing in the registration books kept for such purpose, not less than fifteen (15) days prior to the redemption date for Bonds in the Daily Mode,
Weekly Mode, or Flexible Mode, and not less than thirty (30) nor more than sixty (60) days prior to the redemption date for Bonds in the Term Rate Mode or Fixed Rate Mode. Each notice of redemption of the Bonds shall identify the Bonds to
be redeemed and shall state, among other things, the redemption date, the redemption price and whether the notice is conditional as described below. So long as DTC or its nominee is the sole registered owner of the Bonds under the Book Entry Only
System, redemption notices shall be sent by the Trustee to Cede & Co. and not to Beneficial Owners except as described above. 
 In
addition to the foregoing notice, further notice shall be given by the Trustee, by first class mail, to registered securities depositories and to at least two national information services, including Standard & Poor’s Called Bond
Record; provided that any such notice to any securities depository which is a registered owner of the Bonds shall be delivered at least two (2) days prior to the general distribution of notices of redemption as provided in this
Section 3.7; and provided further that such notices to Standard & Poor’s Called Bond Record shall not be a condition to such redemption and failure to so mail shall not affect the validity of any such redemption proceeding.

 Any notice of optional redemption may state that the redemption is conditioned on the Trustee’s receipt of moneys for such redemption
on or prior to the opening of business on the redemption date. If such moneys are not so received, the redemption of the Bonds for which notice was given will not be made. If such redemption is not effectuated, the Trustee will, within five
(5) days thereafter, give notice in the manner in which the notice of redemption was given that such moneys were not so received. 
 Any
notice mailed as provided in this Section 3.7 shall be conclusively presumed to have been duly given, whether or not the registered owner receives the notice. 
 Notwithstanding anything herein to the contrary, no notice of redemption is required to be given for a redemption occurring on a Mandatory Purchase Date. 
 Section 3.8. Redemption Payments. On or prior to the date fixed for redemption, funds shall be deposited (including by making a
draw on the Credit Enhancement or any Alternate Credit Enhancement) with the Trustee to pay, and Trustee is hereby authorized and directed to apply such funds to the payment of, the Bonds or portions thereof called, together with accrued interest
thereon to the redemption date. Upon the giving of notice and the deposit of funds for redemption, interest on the Bonds or portions thereof thus called shall no longer accrue after the date fixed for redemption. 
 Section 3.9. Cancellation. All Bonds which have been redeemed shall not be reissued but shall be canceled and disposed of by the
Trustee in accordance with Section 2.18 hereof. 
  

 34 







 Section 3.10. Partial Redemption of Bonds. If less than all the
Bonds are to be redeemed, such partial redemption shall be in multiples of $5,000 ($1,000, in the case of Bonds in the Flexible Mode), and the portion of any Bond to be redeemed shall be selected by the Trustee so that all Bonds that remain
outstanding shall be in Authorized Denominations. Upon surrender of any Bond for redemption in part only, the Issuer shall execute and the Trustee shall authenticate and deliver to the Owner thereof a new Bond or Bonds in the same form and of
Authorized Denominations in an aggregate principal amount equal to the unredeemed portion of the Bond surrendered. 
  

 35 







 ARTICLE IV 
 PURCHASE OF BONDS 
 Section 4.1. Optional Tenders of
Bonds in the Daily Mode or the Weekly Mode. Subject to Section 4.6 hereof, the Beneficial Owners of Bonds in a Daily Mode or a Weekly Mode may elect to have their Bonds (or portions
of those Bonds in Authorized Denominations so long as the portion of the Bond not so tendered is in a principal amount equal to an Authorized Denomination) purchased on any Business Day at a price equal to the Purchase Price, upon delivery of a
Tender Notice to the Tender Agent by the Tender Notice Deadline. Immediately upon receipt of a Tender Notice, the Tender Agent shall notify the Remarketing Agent and provide the Remarketing Agent with a copy of such Tender Notice. 
 Section 4.2. Mandatory Purchase on Mandatory Purchase Date. The Bonds shall be subject to mandatory
purchase on each Mandatory Purchase Date. The Tender Agent shall give notice of such mandatory purchase by mail to the Owners of the Bonds subject to mandatory purchase no less than fifteen (15) days prior to any Mandatory Purchase Date
described in clauses (i) through (vi) of the definition thereof, and as soon as practicable following receipt by the Trustee of notice from the Credit Provider in the case of the Mandatory Purchase Date described in clause (vii) of
the definition thereof. No notice shall be given of the Mandatory Purchase Date at the end of each Interest Period for Flexible Rate Bonds. Any notice shall state the Mandatory Purchase Date, the Purchase Price, the numbers of the Bonds to be
purchased if less than all of the Bonds owned by such Owner are to be purchased, and that interest on Bonds subject to mandatory purchase shall cease to accrue from and after the Mandatory Purchase Date. The failure to mail such notice with respect
to any Bond shall not affect the validity of the mandatory purchase of any other Bond with respect to which notice was so mailed. Any notice mailed will be conclusively presumed to have been given, whether or not actually received by any Owner or
Beneficial Owner. 
 Upon the receipt by the Trustee of notice from the Credit Provider, within seven (7) calendar days after the
presentation of demand for a drawing under the Credit Enhancement to pay regularly scheduled interest on the Bonds, that there shall be no reinstatement of the amount so drawn under the terms of the Credit Enhancement, the Trustee shall promptly
(and in any event within two (2) Business Days) draw on the Credit Enhancement in accordance with its terms in an amount equal to the Purchase Price of all the Bonds. 
 Section 4.3. Remarketing of Bonds; Notices. 
 (a) Remarketing of Bonds. The Remarketing Agent shall use its best efforts to offer for sale: 
 (i) all Bonds or portions thereof as to which notice of tender pursuant to Section 4.1 hereof has been given; and 
  

 36 







 (ii) all Bonds required to be purchased on a Mandatory Purchase Date described in clauses (i), (ii),
(iii) or (iv) of the definition thereof; and 
 (iii) any Liquidity Provider Bonds (A) purchased on a Purchase Date described
in clause (i) or (ii) above, (B) with respect to which the Liquidity Provider has provided notice to the Trustee and the Remarketing Agent that it is ready to reinstate the Available Amount upon receipt of the proceeds (in immediately
available funds) from the Tender Agent in an amount equal to the principal and accrued interest that the Liquidity Provider had been required to pay on the Liquidity Provider Bonds, (C) with respect to which an Alternate Liquidity Facility and
Alternate Credit Enhancement is in effect (if such funds were secured by a Credit Enhancement prior to becoming Liquidity Provider Bonds which Credit Enhancement is no longer in effect), or (D) which are being marketed as Fixed Rate Bonds. The
Remarketing Agent will not remarket Bonds to the Company or any affiliate thereof. In connection with the remarketing of any Bonds with respect to which notice of redemption or notice of mandatory purchase has been given, the Remarketing Agent will
notify each person to which such Bonds are remarketed of such notice of redemption or notice of mandatory purchase. 
 Anything in this
Indenture to the contrary notwithstanding, if there shall have occurred and be continuing either a Credit Provider Failure or a Liquidity Provider Failure, the Remarketing Agent shall not remarket any Bonds. All other provisions of this Indenture,
including without limitation, those relating to the setting of interest rates and Interest Periods and mandatory and optional purchases, shall remain in full force and effect during the continuance of such Event of Default. 
 (b) Notice of Remarketing; Registration Instructions; New Bonds. On each date on which a Bond is to be
purchased: 
 (i) the Remarketing Agent shall notify by Electronic Means the Tender Agent by 11:30 A.M. of the principal amount of tendered
Bonds it has remarketed; 
 (ii) unless the Remarketing Agent has delivered the notice described in clause (i) above, the Remarketing
Agent shall notify the Tender Agent by Electronic Means not later than 1:00 P.M. of such information as may be necessary to register and deliver Bonds remarketed with respect thereto; 
 (iii) the Remarketing Agent shall cause the proceeds of the remarketing by such Remarketing Agent of tendered Bonds to be paid to the Tender Agent in
immediately available funds not later than 11:45 A.M., New York City time, on the Purchase Date for such Bonds; and 
 (iv) if the Bonds are
no longer in the Book-Entry System, the Tender Agent shall authenticate new Bonds for the respective purchasers thereof which shall be available for pick-up by the Remarketing Agent not later than 2:30 P.M. 
  

 37 







 (c) Draw on Liquidity Facility. On each date on which a Bond is to be
purchased, if the Remarketing Agent shall have given notice to the Tender Agent pursuant to clause (b)(i) above that it has been unable to remarket any of the Bonds, the Tender Agent shall direct the Trustee (if the two are separate entities) to
draw on the Liquidity Facility (or if no Liquidity Facility is in effect, request funds from the Company) by 12:00 noon in an amount equal to the Purchase Price of all such Bonds which have not been successfully remarketed. If a Liquidity Facility
is in effect, the Trustee shall also give the Company notice by 2:30 P.M. on the Purchase Date if it does not have funds in the Remarketing Proceeds Account and the Liquidity Facility Purchase Account sufficient to pay the Purchase Price of Bonds
tendered on such Purchase Date. 
 Section 4.4. Source of Funds for Purchase of
Bonds. By 3:00 P.M. on the date on which a Bond is to be purchased, and except as set forth in Section 4.6(b)(ii) hereof, the Tender Agent shall purchase tendered Bonds from the tendering Owners at the applicable Purchase Price by wire
transfer in immediately available funds. Funds for the payment of such Purchase Price shall be derived solely from the following sources in the order of priority indicated and none of the Tender Agent, the Trustee nor the Remarketing Agent shall be
obligated to provide funds from any other source: 
 (a) immediately available funds on deposit in the Remarketing Proceeds Account;

 (b) immediately available funds on deposit in the Liquidity Facility Purchase Account; and 
 (c) moneys of the Company on deposit in the Company Purchase Account. 
 The Company shall be obligated to deposit amounts into the Company Purchase Account sufficient to pay the Purchase Price to the extent that amounts on deposit in the Remarketing Proceeds Account and the Liquidity
Facility Purchase Account are insufficient therefor. 
 Section 4.5. Delivery of Bonds. On each date on
which a Bond is to be purchased, such Bond shall be delivered as follows: 
 (a) Bonds sold by the Remarketing Agent and described in
Section 4.4(a) hereof shall be delivered by the Remarketing Agent to the purchasers of such Bonds by 3:00 P.M.; and 
 (b) Bonds
purchased by the Tender Agent with moneys described in Section 4.4(b) hereof shall be registered immediately in the name of the Liquidity Provider or its nominee (which may be the Securities Depository) or, if applicable, the name of any
collateral agent or trustee for a secured creditor of the Company, at the direction of the Liquidity Provider, on or before 3:00 P.M. 
  

 38 







 (c) Bonds purchased by the Company with moneys described in Section 4.4(c) hereof shall be
registered immediately in the name of the Company or its nominee or, if applicable, the name of any collateral agent or trustee for a secured creditor of the Company, on or before 3:00 P.M. Bonds so owned by the Company shall continue to be
outstanding under the terms of this Indenture and be subject to all of the terms and conditions of this Indenture and shall be subject to remarketing by the Remarketing Agent. 
 Section 4.6. Book-Entry Tenders. 
 (a) Notwithstanding any other provision of this Article IV to the contrary, all tenders for purchase during any period in which the Bonds are registered in the name of Cede & Co. (or the nominee of any
successor Securities Depository) shall be subject to the terms and conditions set forth in the Representations Letter and to any regulations promulgated by DTC (or any successor Securities Depository). For so long as the Bonds are registered in the
name of Cede & Co., as nominee for DTC, the tender option rights of Holders of Bonds may be exercised only by DTC by giving notice of its election to tender Bonds or portions thereof at the times and in the manner described above.
Beneficial Owners will not have any rights to tender Bonds directly to the Tender Agent. Procedures under which a Beneficial Owner may direct a Direct Participant or DTC, or an Indirect Participant of DTC acting through a Direct Participant of DTC,
to exercise a tender option right in respect of Bonds or portions thereof in an amount equal to all or a portion of such Beneficial Owner’s beneficial ownership interest therein shall be governed by standing instructions and customary practices
determined by such Direct Participant or Indirect Participant. For so long as the Bonds are registered in the name of Cede & Co., as nominee for DTC, delivery of Bonds required to be tendered for purchase shall be effected by the transfer
on the applicable Purchase Date of a book-entry credit to the account of the Tender Agent of a beneficial interest in such Bonds. 
 (b)
Notwithstanding anything expressed or implied herein to the contrary, so long as the Book-Entry System for the Bonds is maintained by the Issuer: 
 (i) there shall be no requirement of physical delivery to or by the Tender Agent, the Remarketing Agent or the Trustee of: 
 (A)
any Bonds subject to mandatory or optional purchase as a condition to the payment of the Purchase Price therefor; 
 (B) any Bonds that have
become Liquidity Provider Bonds; or 
 (C) any remarketing proceeds of such Bonds or Liquidity Provider Bonds; and 
 (ii) except as provided in (iii) below, none of the Trustee, the Tender Agent nor the Paying Agent shall have any responsibility for paying the
Purchase Price of any tendered Bond or for remitting remarketing proceeds to any person; and 
  

 39 







 (iii) the Tender Agent’s sole responsibilities in connection with the purchase and remarketing of a
tendered Bond shall be to: 
 (A) draw upon the Liquidity Facility in the event the Remarketing Agent notifies the Tender Agent as provided
herein that such Bond has not been remarketed on or before the Purchase Date therefor, which draw shall be in an amount equal to the difference between such Purchase Price and any remarketing proceeds received by Remarketing Agent in connection with
a partial remarketing of such Bond, and to remit the amount so drawn to or upon the order of the Securities Depository for the benefit of the tendering Beneficial Owners; and 
 (B) remit any proceeds derived from the remarketing of a Liquidity Provider Bond to the Liquidity Provider. 
 Section 4.7. No Book-Entry System. If at any time the Bonds shall no longer be in the Book-Entry System, the following
procedures shall be followed: 
 (a) Bonds shall be delivered (with all necessary endorsements) at or before 12:00 noon on the Purchase Date
at the office of the Paying Agent in New York, New York; provided, however, that payment of the Purchase Price shall be made pursuant to this Section only if the Bond so delivered to the Paying Agent conforms in all respects to the description
thereof in the notice described in this Section. Payment of the Purchase Price with respect to purchases under this Section shall be made to the Owners of tendered Bonds by wire transfer in immediately available funds by the Paying Agent by 3:00
P.M. on the Purchase Date. 
 (b) If a Bond to be purchased is not delivered by the Owner to the Paying Agent by 12:00 noon on the date in
which such Bond is to be purchased, the Paying Agent shall hold any funds received for the purchase of those Bonds in the Purchase Fund in trust and shall pay such funds to the former Owners of the Bonds upon presentation of the Bonds. Such
undelivered Bonds shall cease to accrue interest as to the former Owners on such purchase date and moneys representing the Purchase Price shall be available against delivery of those Bonds at the Principal Office of the Paying Agent; provided,
however, that any funds which shall be so held by the Paying Agent and which remain unclaimed by the former Owner of a Bond not presented for purchase for a period of two (2) years after delivery of such funds to the Paying Agent, shall, to the
extent permitted by law, upon request in writing by the Company and the furnishing of security or indemnity to the Paying Agent’s satisfaction, be paid to the Company free of any trust or lien and thereafter the former Owner of such Bond shall
look only to the Company and then only to the extent of the amounts so received by the Company without any interest thereon and the Paying Agent shall have no further responsibility with respect to such moneys or payment of the Purchase Price of
such Bonds. The Paying Agent shall authenticate a replacement Bond for any undelivered Bond which may then be remarketed by the Remarketing Agent. 
  

 40 







 (c) The Paying Agent shall hold all Bonds properly tendered to it for purchase hereunder as agent and
bailee of, and in escrow for the benefit of, the respective Owners of the Bonds which shall have so tendered such Bonds until moneys representing the Purchase Price of such Bonds shall have been delivered to or for the account of or to the order of
such Owners. 
 Section 4.8. Credit Enhancement and Liquidity Facility. (a) While the
Credit Enhancement is in effect with respect to any Bonds, the Trustee shall, on the Business Day preceding each Interest Payment Date and Principal Payment Date, before 4:00 P.M. on such day, draw on the Credit Enhancement in accordance with the
terms thereof so as to receive thereunder with respect to Bonds covered by the Credit Enhancement by 1:00 P.M. on said Interest Payment Date and Principal Payment Date, an amount, in immediately available funds, equal to the amount of interest and
principal payable on such Bonds on such Interest Payment Date and Principal Payment Date. The proceeds of such draws shall be deposited in the Credit Enhancement Account of the Bond Fund pursuant to Section 6.2(b) hereof. 
 (b) If a Liquidity Facility is in effect, on each date on which a Bond is to be purchased, the Tender Agent (if it is the beneficiary of the Liquidity
Facility) or the Trustee (if it is the beneficiary of the Liquidity Facility) at the direction of the Tender Agent as provided in Section 4.3(c) hereof, by demand given by Electronic Means before 12:00 noon, shall draw on the Liquidity Facility
in accordance with the terms thereof so as to receive thereunder by 2:30 P.M. on such date an amount, in immediately available funds, sufficient, together with the proceeds of the remarketing of Bonds on such date, to enable the Tender Agent to pay
the Purchase Price in connection therewith. The proceeds of such draw shall be paid to the Tender Agent, who shall deposit said proceeds in the Liquidity Facility Purchase Account pursuant to Section 4.9(b) hereof. 
 (c) Notwithstanding the foregoing paragraphs of this Section, if the Credit Provider and the Liquidity Provider are the same entity, the Trustee shall
not draw on the Credit Enhancement with respect to any payments due or made in connection with Liquidity Provider Bonds. In no event shall the Trustee draw on the Credit Enhancement with respect to any payments made or made in connection with Bonds
not covered by the Credit Enhancement or Bonds owned by the Company. 
 (d) The Company may provide an Alternate Credit Enhancement or
Alternate Liquidity Facility on any Business Day not later than the fifth (5th) Business Day prior to the Expiration Date of the Credit Enhancement or Liquidity Facility then in effect. The Company shall give the Notice Parties written notice
of the proposed substitution of an Alternate Credit Enhancement or Alternate Liquidity Facility no less than two (2) Business Days prior to the date on which the Trustee is required to provide notice of the proposed substitution to the
Beneficial Owners of the Bonds. The Trustee shall give notice of such Substitution Date in accordance with Section 4.2. On or before the Substitution Date there shall be delivered to the Trustee or the Tender Agent, as applicable (i) the
Alternate Credit Enhancement or the Alternate Liquidity Facility in substitution for the Credit Enhancement or Liquidity Facility then in effect, (ii) a 

  

 41 







 
Favorable Opinion of Bond Counsel, (iii) a written Opinion of Counsel for the provider of the Alternate Credit Enhancement or Alternate Liquidity
Facility, as applicable, to the effect that such Alternate Credit Enhancement or Alternate Liquidity Facility is a valid, legal and binding obligation of the provider thereof, and that the Alternate Credit Enhancement or Alternate Liquidity Facility
is not subject to registration under the Securities Act of 1933 (or, if subject to registration, that registration has been effected or is not required in connection with the remarketing or offering of the Bonds), and (iv) unless waived by such
entity, written evidence satisfactory to the Credit Provider and the Liquidity Provider of the provision for purchase from the Liquidity Provider of all Liquidity Provider Bonds, at a price equal to the principal amount thereof plus accrued and
unpaid interest, and payment of all amounts due to the Credit Provider and the Liquidity Provider under the Reimbursement Agreement(s) on or before the effective date of such Alternate Letter of Credit or Alternate Liquidity Facility. Upon the
satisfaction of the conditions described in the preceding sentence and provided a draw has been made on any Liquidity Facility then in effect in accordance with the provisions of Section 4.8(b) hereof, the Trustee shall accept such Alternate
Credit Enhancement or Alternate Liquidity Facility on the close of business on the Substitution Date and shall surrender the Credit Enhancement or Liquidity Facility then in effect to the provider thereof on the Substitution Date, provided that no
such surrender shall occur unless and until the draw on any such Liquidity Facility shall have been honored. If any condition to the substitution is not satisfied, the substitution shall not occur but the Bonds shall remain subject to mandatory
purchase on the proposed Substitution Date. 
 (e) In the event of an extension of the Expiration Date, the Company shall give to the Notice
Parties, a written notice of the new Expiration Date no less than two (2) Business Days prior to the date on which the Trustee otherwise would be required to provide notice to the Beneficial Owners of the Bonds that a Mandatory Purchase Date
would occur as a result of the Expiration Date occurring for such Credit Enhancement or Liquidity Facility. 
 (f) The references to
Liquidity Facility and Liquidity Provider shall be disregarded during any period during which a Liquidity Facility is not required to be in effect. 
 Section 4.9. Purchase Fund. There is hereby established and there shall be maintained with the Tender Agent, as agent for the Trustee, a separate, segregated fund to be known as the “Purchase Fund.” The
Tender Agent shall further establish separate, segregated accounts within the Purchase Fund to be known as the “Liquidity Facility Purchase Account” and the “Remarketing Proceeds Account” and the “Company Purchase
Account.” 
 (a) Remarketing Proceeds Account. Upon receipt of the proceeds of a remarketing of a Bond on the date
such bond is to be purchased, the Tender Agent shall deposit such proceeds in the Remarketing Proceeds Account for application to the Purchase Price of the Bonds. Notwithstanding the foregoing, upon the receipt of the proceeds of a remarketing of
Liquidity Provider Bonds, the Tender Agent shall immediately pay such proceeds to the Liquidity Provider to the extent of any amount owing to the Liquidity Provider. 
  

 42 







 (b) Liquidity Facility Purchase Account. Upon receipt from the Trustee of the
immediately available funds transferred to the Tender Agent pursuant to Section 4.4(b) hereof, the Tender Agent shall deposit such money in the Liquidity Facility Purchase Account for application to the Purchase Price of the Bonds to the extent
that the moneys on deposit in the Remarketing Proceeds Account shall not be sufficient. Any amounts deposited in the Liquidity Facility Purchase Account and not needed with respect to the Purchase Price for any Bonds shall be immediately returned to
the Liquidity Provider. 
 (c) Company Purchase Account. Upon receipt of Funds from the Company pursuant to
Section 4.4(c) hereof, the Tender Agent shall deposit such Funds in the Company Purchase Account for application to the Purchase Price of the Bonds. Any amounts deposited in the Company Purchase Account and not needed with respect to the
Purchase Price for any Bonds shall be immediately refunded to the Company or as the Company may direct pursuant to the Company Credit Facility. 
 (d) Investment. Amounts held in the Liquidity Facility Purchase Account and the Remarketing Proceeds Account by the Paying Agent shall be held uninvested and separate and apart from all other funds and accounts.

commitments, including, without limitation, those in the various sections of this Article V, it pledges no funds or assets other than the Trust Estate in the manner and to the extent herein specified, but nothing herein shall be construed as
prohibiting the Issuer from using any other funds or assets.

 Section 5.7. Prohibited Activities. The Issuer covenants that it shall not take any action or suffer or
permit any action to be taken or condition to exist which causes or may cause the interest payable on the Bonds to be subject to federal income taxation. Without limiting the generality of the foregoing, the Issuer covenants that the proceeds of the
sale of the Bonds, the earnings thereon, and any other moneys on deposit in any fund or account maintained in respect of the Bonds (whether such moneys were derived from the proceeds of the sale of the Bonds or from other sources), will not be used
directly or indirectly in such manner as to cause the Bonds to be treated as “arbitrage bonds” within the meaning of Section 148 of the Code. 
 Section 5.8. Transfer, Reduction and Return of Credit Enhancement. The Trustee shall not sell, assign or transfer the Credit Enhancement except to a
successor trustee under this Indenture in accordance with the terms of the Credit Enhancement. The Trustee shall submit to the Credit Provider such certificates or other documents on a timely basis as may be required by the terms of the Credit

drawn under the Credit Enhancement on account of the payment of the principal or Purchase Price of, or interest on the Bonds, the Trustee shall exclude any such amounts in respect of any Bonds which are Bonds owned by the Issuer or the Company on
the date such payment is due, and (ii) amounts drawn by the Trustee under the Credit Enhancement shall not be applied to the payment of the principal or Purchase Price of, or interest on, any Bonds which are owned by the Issuer or the Company
on the date such payment is due. 
 Section 6.4. Withdrawals from Bond Fund. The Bond Fund shall be
in the name of the Issuer, designated as set forth in Section 6.1, and the Issuer hereby irrevocably authorizes and directs the Trustee to withdraw from the Bond Fund sufficient funds to pay the principal of and interest on the Bonds when due
(including at maturity or redemption prior to maturity) and to use such funds for the purpose of paying principal and interest in accordance with the provisions hereof pertaining to payment, which authorization and direction the Trustee hereby
accepts. To the extent amounts are paid on the Bonds by draws on the Credit Enhancement and there are amounts in the Bond Fund resulting from payments made by the Company pursuant to Section 5.2(a) of the Loan Agreement, the Trustee is directed
to use such amounts in the General Account of the Bond Fund to reimburse the Credit Provider, on behalf of the Company, in respect of such draw.

 Section 6.5. Non-Presentment of Bonds. In the event any Bonds shall not
be presented for payment when the principal thereof becomes due, either at maturity or otherwise, or at the date fixed for redemption thereof, if there shall have been deposited with the Trustee for that purpose, or left in trust if previously so
deposited, funds sufficient to pay the principal thereof, together with all interest unpaid and due thereon, to the due date thereof, for the benefit of the Owner thereof, all liability of the Issuer to the Owner thereof for the payment of the
principal thereof and interest thereon shall forthwith cease, determine and be completely discharged, and thereupon it shall be the duty of the Trustee to hold such fund or funds, without liability for interest thereon, for benefit of the Owner of
such Bond, who shall thereafter be restricted exclusively to such fund or funds, for any claim of whatever nature on his part under this Indenture or on, or with respect to, the Bond. 
 Section 6.6. Fees, Expenses and Charges of Issuer and Trustee. It is understood and
agreed that pursuant to the provisions of Section 5.3(b) of the Loan Agreement, the Company agrees to pay the reasonable fees, expenses and charges of the Trustee, the Remarketing Agent, and any Paying Agent as authorized and provided by this
Indenture and, pursuant to Section 5.3(c) of the Loan Agreement, the reasonable fees, expenses and charges of the Issuer as authorized, required and provided by this Indenture and by the Loan Agreement. All such payments under the Loan

Trustee under any provision of this Indenture shall be held by the Trustee in trust, and except for moneys deposited with or paid to the Trustee for the redemption of Bonds notice of which redemption has been duly given, for moneys deposited with or
paid to the Trustee pursuant to Article X hereof, and for moneys held pursuant to Section 4.4, Section 4.9, or Section 6.5 hereof, shall, while held by the Trustee, 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 provisions of the Loan Agreement calling for the Trustee to hold, administer and disburse the same in accordance with the specific provisions of the Loan Agreement shall be held,
administered and disbursed pursuant to such provisions, and where required by the provisions of the Loan Agreement the Trustee shall set the same aside in a separate account. The Issuer agrees that if it shall receive any moneys pursuant to
applicable provisions of the Loan 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 Loan Agreement pursuant to which the
Issuer may have received the same. Furthermore, if for any reason the Loan 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 in connection with
the Bonds, it will forthwith upon receipt thereof pay the same over to the Trustee to be held, administered and disbursed by the Trustee in 

  

 48

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 6.8. Refund to Company of Excess Payments. Anything herein to the contrary notwithstanding,
the Trustee is authorized and directed to refund to the Company, or as directed by the Company pursuant to the Company Credit Facility, if applicable, all excess amounts as specified in the Loan Agreement, whether such excess amounts be in the Bond
Fund or in special accounts. 
 Section 6.9. Termination of Rights of Bondholders. Anything
herein to the contrary notwithstanding, including, without limitation, the provisions of this Article V and of Article X and Article X hereof, all rights of any Owner of any Bond hereunder to or with respect to any moneys or investments held in any
fund hereunder shall terminate at the expiration of two (2) years from the date of maturity of such Bond, whether by scheduled maturity or by call for redemption prior to maturity in accordance with the terms hereof, with respect to the
principal thereof, or at the expiration of two (2) years from an Interest Payment Date with respect to the interest payable on such date.

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
Bondholders of not less than 10% in aggregate principal amount of the Bonds then outstanding, unless the Trustee, or the Trustee and Bondholders of an aggregate principal amount of Bonds not less than the aggregate principal amount of Bonds the
Bondholders 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, 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 by the Issuer, or the Company on behalf of the Issuer, within such period and is being diligently pursued;

 (f) The occurrence and continuance of a Credit Provider Failure or a Liquidity Provider Failure; and

 57 







 Section 11.2. Acceleration. Upon the occurrence and during the continuance of:

 (i) an Event of Default described in clause (f) of Section 11.1 hereof, the Trustee shall, 
 (ii) an Event of Default described in clause (a), (b), (c), (d), (e), or (g) of Section 11.1 hereof, and upon the written
request of the Credit Provider (so long as the Credit Enhancement shall be in effect and there shall not have occurred and be continuing a Credit Provider Failure), the Trustee shall, or 
 (iii) an Event of Default described in clause (a), (b), (c), (d), (e) or (g) of Section 11.1 hereof, provided the Credit
Enhancement is not then in effect or there shall have occurred and be continuing a Credit Provider Failure, the Trustee may, and upon the written request of the Owners of two-thirds (2/3) in aggregate principal amount of Bonds outstanding
hereunder, the Trustee shall, 
 by notice in writing delivered to the Issuer, the Company, and the Credit Provider (so long as the Credit Enhancement is
outstanding) declare the principal of all Bonds hereby secured then outstanding and the interest accrued thereon immediately due and payable, and such principal and interest shall thereupon become and be immediately due and payable and interest
shall cease to accrue on all Bonds issued hereunder. 
 Section 11.3. Credit Enhancement. Except with respect to
any Bond held by the Company or pledged to the Credit Provider, upon an acceleration pursuant to Section 11.2 hereof, the Trustee shall promptly draw moneys under the Credit Enhancement in accordance with the terms thereof to the extent
necessary to make timely payments of principal of and interest on the Bonds. 
 Section 11.4. Other Remedies;
Rights of Bondholders. Upon the occurrence and during the continuance of an Event of Default, the Trustee may, as an alternative, pursue any available remedy by suit at law or in equity to enforce the payment of the principal of
and interest on the Bonds then outstanding hereunder. 
 If an Event of Default shall have occurred, and if it shall have been requested so
to do by the Owners of two-thirds (2/3) in aggregate principal amount of Bonds outstanding hereunder and shall have been indemnified as provided in Section 12.1 hereof, the Trustee shall be obligated to exercise such one or more of the
rights and powers conferred upon it by this Section and by Section 11.2 as the Trustee, being advised by counsel, shall deem most expedient in the interests of the Bondholders. 
 No remedy by the terms of this Indenture conferred upon or reserved to the Trustee (or to the Bondholders or the Credit Provider) is intended to be
exclusive of any other remedy, but each and every such remedy shall be cumulative and shall be in addition to any other remedy given hereunder or now or hereafter existing at law or in equity or by statute. 
  

 58 







 No delay or omission to exercise any right or power accruing upon any default or Event of Default shall
impair any such right or power or shall be construed to be a waiver of any such default or Event of Default or acquiescence therein; and every such right and power may be exercised from time to time and as often as may be deemed expedient.

 No waiver of any default or Event of Default hereunder, whether by the Trustee or by the Bondholders, shall extend to or shall affect any
subsequent default or Event of Default or shall impair any rights or remedies consequent thereon. 
 Nothing in this Section 11.4 shall
be construed to relieve the Trustee of its obligation to cause an acceleration when required or to pay the Bondholders the amounts due them when due. 
 Section 11.5. Rights of Bondholders to Direct Proceedings. Anything in this Indenture to the contrary notwithstanding but subject to Section 11.13 hereof, the
Owners of a majority in aggregate principal amount of Bonds outstanding hereunder shall have the right, at any time, by an instrument or instruments in writing executed and delivered to the Trustee, to direct the method and place of conducting all
proceedings to be taken in connection with the enforcement of the terms and conditions of this Indenture, or for the appointment of a receiver or any other proceeding hereunder; provided that such direction shall not be otherwise than in accordance
with the provisions of law and of this Indenture; provided, further, that if the Credit Enhancement shall be in effect and there shall not have occurred and be continuing a Credit Provider Failure, the Credit Provider shall have the right to direct
the proceedings and all other remedies hereunder. 
 Section 11.6. Appointment of Receiver. Upon the
occurrence of an Event of Default, and upon the filing of a suit or other commencement of judicial proceedings to enforce the rights of the Trustee and of the Bondholders under this Indenture, the Trustee shall be entitled, as a matter of right, to
the appointment of a receiver or receivers of the Trust Estate and of the tolls, rents, revenues, issues, earnings, income, products and profits thereof, pending such proceedings with such powers as the court making such appointment shall confer.

 Section 11.7. Waiver. In case of an Event of Default on its part, as aforesaid, to the extent that such rights may then
lawfully be waived, neither the Issuer nor anyone claiming through it or under it shall or will set up, claim, or seek to take advantage of any appraisement, valuation, stay, extension or redemption laws now or thereafter in force, in order to
prevent or hinder the enforcement of this Indenture, but the Issuer, for itself and all who may claim through or under it, hereby waives, to the extent that it lawfully may do so, the benefit of all such laws and all right of appraisement and
redemption to which it may be entitled under the laws of the State of Arkansas. 
  

 59 







 Section 11.8. Application of Moneys. Provided that all moneys drawn by
the Trustee under the Credit Enhancement shall be applied solely to the payment of the principal of and interest on the Bonds, moneys remaining after discharge of costs, charges and liens prior to this Indenture shall be applied by the Trustee as
follows: 
 (a) Unless the principal of all the Bonds shall have become or shall have been declared due and payable, all such moneys shall be
applied: 
 First: To the payment to the persons entitled thereto of all installments of interest then due, in the order of
the maturity of the installments of such interest, and, if the amount available shall not be sufficient to pay in full any particular installment, then to the payment ratably, according to the amounts due on such installment, to the persons entitled
thereto, without any discrimination or privilege; 
 Second: To the payment to the persons entitled thereto of the unpaid
principal of any of the Bonds which shall have become due (other than Bonds called for redemption for the payment of which moneys are held pursuant to the provisions of this Indenture), in the order of their due dates, with interest on such Bonds
from the respective dates upon which they become due, and, if the amount available shall not be sufficient to pay in full Bonds due on any particular date, together with such interest, then to the payment ratably, according to the amount of
principal due on such date, to the persons entitled thereto without any discrimination or privilege of any Bond over any other Bond and without preference or priority of principal over interest or of interest over principal; and 
 Third: To the payment of the interest on and the principal of the Bonds, and to the redemption of Bonds, all in accordance with the
provisions of Article V of this Indenture. 
 (b) If the principal of all the Bonds shall have become due or shall have been declared due and
payable, all such moneys shall be applied to the payment of the principal and interest then due and unpaid upon the Bonds, without preference or priority of principal over interest or of interest over principal, or of any Bond over any other Bond,
ratably, according to the amounts due respectively for principal and interest, to the person entitled thereto without discrimination or privilege. 
 (c) If the principal of all the Bonds shall have been declared due and payable, and if such declaration shall thereafter have been rescinded and annulled under the provisions of this Article then, subject to the provisions of paragraph
(b) of this Section in the event that the principal of all the Bonds shall later become due or be declared due and payable, the moneys shall be applied in accordance with the provisions of paragraph (a) of this Section. 
 Whenever moneys are to be applied by the Trustee pursuant to the provisions of this Section, such moneys shall be applied by it at such times, and from
time to time, as it shall determine, having due regard to the amount of such moneys available for application and the 

  

 60 







 
likelihood of additional moneys becoming available for such application in the future. Whenever the Trustee shall apply such funds, it shall fix the date
(which shall be an Interest Payment Date unless it shall deem another date more suitable) upon which such application is to be made and upon such date (other than in the case of a declaration under Section 11.2 hereof) interest on the amounts
of principal to be paid on such dates shall cease to accrue. The Trustee shall give such notice as it may deem appropriate of the deposit with it of any such moneys and of the fixing of any such date and shall not be required to make payment to the
Owner of any unpaid Bond until such Bond shall be presented to the Trustee for appropriate endorsement or for cancellation if fully paid. 
 Section 11.9. Remedies Vested in Trustee. All rights of action (including the right to file proof of claim) under this Indenture or under any of the Bonds may be enforced by the Trustee without the
possession of any of the Bonds or the production thereof in any trial or other proceeding relating thereto and any such suit or proceeding instituted by the Trustee shall be brought in its name as Trustee, without the necessity of joining as
plaintiffs or defendants any Owners of the Bonds hereby secured, and any recovery of judgment shall be for the equal benefit of the Owners of the outstanding Bonds. 
 Section 11.10. Rights and Remedies of Bondholders. No Owner of any Bond shall have any right to institute any suit, action or proceeding in equity or at law for the
enforcement of this Indenture or for the execution of any trust hereof or for the appointment of a receiver or any other remedy hereunder, unless a default has occurred of which the Trustee has been notified as provided in subsection (g) of
Section 12.1, or of which by said subsection it is deemed to have notice, nor unless such default shall have become an Event of Default and the Owners of two-thirds (2/3) in aggregate principal amount of Bonds outstanding hereunder shall
have made written request to the Trustee and shall have offered it reasonable opportunity either to proceed to exercise the powers hereinbefore granted or to institute such action, suit or proceeding in its own name, nor unless also they have
offered to the Trustee indemnity as provided in Section 12.1 nor unless the Trustee shall thereafter fail or refuse to exercise the powers hereinbefore granted, or to institute such action, suit or proceeding in its own name; and such
notification, request and offer of indemnity are hereby declared in every such case at the option of the Trustee to be conditions precedent to the execution of the powers and trusts of this Indenture, and to any action or cause of action for the
enforcement of this Indenture or for the appointment of a receiver or for any other remedy hereunder; it being understood and intended that no one or more Owners of the Bonds shall have any right in any manner whatsoever to affect, disturb or
prejudice the lien of this Indenture by his or their action or to enforce any right hereunder except in the manner herein provided, and that all proceedings at law or in equity shall be instituted, held and maintained in the manner herein provided
for the equal benefit of the Owners of all Bonds outstanding hereunder. Nothing in this Indenture contained shall, however, affect or impair the right of any Bondholder to enforce the payment of the principal of and interest on any Bonds at and
after the maturity thereof, or the obligation of the Issuer to pay the principal of and interest on each of the Bonds issued hereunder to the respective Owners thereof at the time and place in said Bonds, and to institute in its own name any suit,
action or proceeding in equity or at law for the enforcement of this Indenture or for the appointment of a receiver or any other remedy hereunder. 
  

 61 







 Section 11.11. Termination of Proceedings. In case the Trustee shall
have proceeded to enforce any right under this Indenture by the appointment of a receiver or otherwise, and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee, then and
in every such case the Issuer and the Trustee shall be restored to their former positions and rights hereunder with respect to the property herein conveyed, and all rights, remedies and powers of the Trustee shall continue as if no such proceedings
had been taken, except to the extent the Trustee is legally bound by such adverse determination. 
 Section 11.12. Waivers
of Events of Default. The Trustee may in its discretion waive any Event of Default hereunder and its consequences and rescind any declaration of maturity of principal and shall do so upon the written request of the Owners
of two-thirds (2/3) in aggregate principal amount of Bonds outstanding hereunder, provided, however, that there shall not be waived (i) any Event of Default described in clause (a), (b) or (c) of Section 11.1 hereof, unless
prior to such waiver or rescission all arrears of principal (due otherwise than by declaration) and interest and all expenses of the Trustee, shall have been paid or provided for, (ii) any Event of Default described in clause (f) of
Section 11.1 hereof, unless prior to such waiver or rescission the Credit Enhancement has been reinstated in full and the Credit Provider has rescinded any related default under the Reimbursement Agreement, and (iii) any Event of Default
without the prior written consent of the Credit Provider (so long as the Credit Enhancement shall be in effect and there shall not have occurred and be continuing a Credit Provider Failure). In case of any such waiver or rescission the Issuer,
Trustee and the Bondholders shall be restored to their former positions and rights hereunder respectively; but no such waiver or rescission shall extend to any subsequent or other default, or impair any right subsequent thereon. 
 Section 11.13. Rights of Credit Provider. Anything herein to the contrary notwithstanding, the Credit Provider
shall, so long as the Credit Enhancement shall be in effect and there shall not have occurred and be continuing a Credit Provider Failure, have the right to direct the taking of actions and enforcement of remedies permitted by this Article XI,
including, without limitation, the declaration of all unpaid amounts payable under this Indenture to be immediately due and payable and the waiver of Events of Default.

 ARTICLE XII 
 TRUSTEE AND PAYING AGENTS 
 Section 12.1. Acceptance of
Trusts. The Trustee hereby accepts the trust imposed upon it by this Indenture, and agrees to perform said trust as an ordinarily prudent trustee under a corporate mortgage, but only upon and subject to the following expressed terms and
conditions: 
 (a) The Trustee may execute any of the trusts or powers hereof and perform any duties required of it by or through attorneys,
agents, receivers or employees, and shall be entitled to advice of counsel concerning all matters of trusts hereof and its duties hereunder, and may in all cases pay reasonable compensation to all such attorneys, agents, receivers and employees as
may reasonably be employed in connection with the trusts hereof. The Trustee may act upon the opinion or advice of any attorney, surveyor, engineer or accountant selected by it in the exercise of reasonable care, or, if selected or retained by the
Issuer prior to the occurrence of a default of which the Trustee has been notified as provided in subsection (g) of this Section 12.1, or of which by said subsection the Trustee is deemed to have notice, approved by the Trustee in the
exercise of such care. The Trustee shall not be responsible for any loss or damage resulting from an action or non-action in accordance with any such opinion or advice. 
 (b) The Trustee shall not be responsible for any recital herein, or in the Bonds (except in respect to the certificate of the Trustee endorsed on such Bonds), or for insuring the property herein conveyed or collecting
any insurance moneys, or for the validity of the execution by the Issuer of this Indenture or of any supplemental indentures or instrument of further assurance, or for the sufficiency of the security for the Bonds issued hereunder or intended to be
secured hereby, or for the value of the title of the property herein conveyed or otherwise as to the maintenance of the security hereof; except that in the event the Trustee enters into possession of a part or all of the property herein conveyed
pursuant to any provision of this Indenture, it shall use due diligence in preserving such property; and the Trustee shall not be bound to ascertain or inquire as to the performance or observance of any covenants, conditions and agreements aforesaid
as to the condition of the property herein conveyed. 
 (c) The Trustee may become the owner of Bonds secured hereby with the same rights
which it would have if not Trustee. 
 (d) The Trustee shall be protected in acting upon any notice, request, consent, certificate, order,
affidavit, letter, telegram or other paper or document believed by it, in the exercise of reasonable care, to be genuine and correct and to have been signed or sent by the proper person or persons. Any action taken by the Trustee pursuant to this
Indenture upon the request or authority or consent of the Owner of any Bond secured hereby, shall be conclusive and binding upon all future Owners of the same Bond and upon Bonds issued in exchange therefor or in place thereof. 
  

 63 







 (e) As to the existence or non-existence of any fact or as to the sufficiency or validity of any
instrument, paper or proceeding, the Trustee shall be entitled to rely upon a certificate of the Issuer signed by its Mayor and attested by its Clerk as sufficient evidence of the facts therein contained and prior to the occurrence of a default of
which it has been notified as provided in subsection (g) of this Section 12.1, or of which by that subsection it is deemed to have notice, and shall also be at liberty to accept a similar certificate to the effect that any particular
dealing, transaction or action is necessary or expedient, but may at its discretion, at the reasonable expense of the Issuer, in every case secure such further evidence as it may think necessary or advisable but shall in no case be bound to secure
the same. The Trustee may accept a certificate of the Clerk of the Issuer under its seal to the effect that a resolution or ordinance in the form therein set forth has been adopted by the Issuer as conclusive evidence that such resolution or
ordinance has been duly adopted, and is in full force and effect. 
 (f) The permissive right of the Trustee to do things enumerated in this
Indenture shall not be construed as a duty of the Trustee, and the Trustee shall be answerable only for its own negligence or willful default. 
 (g) The Trustee shall not be required to take notice or be deemed to have notice of any default hereunder (except a default under clause (a), (b) or (c) of Section 11.1 hereof concerning which the Trustee shall be deemed to
have notice) unless the Trustee shall be specifically notified in writing of such default by the Issuer, by the Credit Provider, or by the Owners of at least ten percent (10%) in aggregate principal amount of Bonds outstanding hereunder and all
notices or other instruments required by this Indenture to be delivered to the Trustee must, in order to be effective, be delivered to the office of the Trustee, and in the absence of such notice so delivered, the Trustee may conclusively assume
there is no such default except as aforesaid. 
 (h) The Trustee shall not be personally liable for any debts contracted or for damages to
persons or to personal property injured or damaged, or for salaries or non-fulfillment of contracts during any period in which it may be in the possession of or managing the real and tangible personal property as in this Indenture provided.

 (i) At any and all reasonable times the Trustee, and its duly authorized agents, attorneys, experts, engineers, accountants and
representatives, shall have the right fully to inspect any and all of the property herein conveyed, including all books, papers and records of the Issuer pertaining to the Project and the Bonds, and to take such memoranda from and in regard thereto
as may be desired, provided, however, that nothing contained in this subsection or in any other provision of this Indenture shall be construed to entitle the above named persons to any information or inspection involving the confidential know-how of
the Company. 
 (j) The Trustee shall not be required to give any bond or surety in respect of the execution of the said trusts and powers or
otherwise in respect of the premises. 
  

 64 







 (k) Notwithstanding anything elsewhere in this Indenture contained, the Trustee shall have the right, but
shall not be required, to demand, in respect of the authentication of any Bonds, the withdrawal of any cash, the release of any property, or any action whatsoever within the purview of this Indenture, any showings, certificates, opinions,
appraisals, or other information, or corporate action or evidence thereof, in addition to that by the terms hereof required as a condition of such action by the Trustee, deemed desirable for the purpose of establishing the right of the Issuer to the
authentication of any Bonds, the withdrawal of any cash, the release of any property, or the taking of any other action by the Trustee. 
 (l) Before taking such action hereunder, the Trustee may require that it be furnished an indemnity bond or other security satisfactory to it for the reimbursement to it of all expenses to which it may be put and to protect it against all
liability, except liability which is adjudicated to have resulted from the gross negligence or willful default of the Trustee, by reason of any action so taken by the Trustee; provided, however, the Trustee shall not require that it be furnished an
indemnity bond prior to (i) declaring the maturity of principal of the Bonds pursuant to Section 11.2 hereof, or (ii) holding, administering and disbursing moneys deposited in the Bond Fund. 
 Section 12.2. Fees, Charges and Expenses of Trustee; Trustee’s Prior
Lien. The Trustee shall be entitled to payment and/or reimbursement for its reasonable fees for services rendered hereunder and all advances, counsel fees and other expenses reasonably and necessarily made or incurred by the Trustee in and
about the execution of the trusts created by this Indenture and in and about the exercise and performance by the Trustee of the powers and duties of the Trustee hereunder, and for all reasonable and necessary costs and expenses incurred in defending
any liability in the premises of any character whatsoever (unless such liability is adjudicated to have resulted from the gross negligence or willful default of the Trustee). Any Paying Agent shall be paid the standard and customary fees and charges
for handling the processing of Bonds and payment of the principal of and premium, if any, and interest on the Bonds, and funds sufficient to pay the same shall be deposited with each Paying Agent on or prior to the dates on which payments are
required to be made on the Bonds. The Issuer has made provisions in the Loan Agreement for the payment of such reasonable and necessary advances, fees, costs and expenses and reference is hereby made to the Loan Agreement for the provisions so made.
In this regard, it is understood that the Issuer pledges no funds or revenues other than those derived from and the avails of the Trust Estate to the payment of any obligation of the Issuer set forth in this Indenture, including the obligations set
forth in this Section 12.2, but nothing herein shall be construed as prohibiting the Issuer from using any other funds and revenues for the payment of any of its obligations under this Indenture. Upon default by the Issuer, but only upon
default, pursuant to the provisions of this Indenture pertaining to default, the Trustee shall have a first lien with right of payment prior to payment on account of principal or interest of any Bond issued hereunder upon the Trust Estate (other
than moneys, securities or obligations held for the redemption or payment of Bonds deemed to have been paid in accordance with Article X hereof, funds held pursuant to Section 4.9 or Section 6.5 hereof, or moneys drawn by the Trustee under
the Credit Enhancement for the payment of the principal of and interest on the Bonds) for such reasonable and necessary advances, fees, costs and expenses incurred by the Trustee. 
  

 65 







 Section 12.3. Notice to Bondholders of Default. The
Trustee shall be required to make demand upon and give notice to the Company and each registered owner of Bonds then outstanding as follows: 
 (a) If the Company shall fail to make any installment payment under the Loan Agreement on the day such payment is due and payable, the Trustee shall give notice to and make demand upon the Company on the next succeeding Business Day.

 (b) If a default occurs of which the Trustee is pursuant to the provisions of Section 12.1(g) deemed to have or is given notice, the
Trustee shall promptly give notice to the Company and to Bondholders generally; provided, however, that no notice shall be required to be given to Bondholders generally unless the default is such that the Bondholders could require the Trustee to act
pursuant to Section 11.2 hereof. 
 Section 12.4. Intervention by Trustee. In any judicial proceeding
to which the Issuer is a party and which in the opinion of the Trustee and its counsel has a substantial bearing on the interests of Owners of Bonds issued hereunder, the Trustee may intervene on behalf of Bondholders and shall do so if requested in
writing by the Credit Provider or the Owners of at least ten percent (10%) of the aggregate principal amount of Bonds outstanding hereunder. The rights and obligations of the Trustee under this Section 12.4 are subject to the approval of
the court having jurisdiction in the premises. 
 Section 12.5. Merger or Consolidation of
Trustee. Any bank or trust company to which the Trustee may be merged, or with which it may be consolidated, or to which it may sell or transfer its trust business and assets as a whole or substantially as a whole, or any bank or trust
company resulting from any such sale, merger, consolidation or transfer to which it is a party, ipso facto, shall be and become successor trustee hereunder and vested with all of the title to the whole property or Trust Estate and all the trusts,
powers, discretions, immunities, privileges, and all other matters as was its predecessor, without the execution or filing of any instrument or any further act, deed or conveyance on the part of any of the parties hereto, anything herein to the
contrary notwithstanding; provided, however, that such successor trustee shall have capital and surplus of at least $50,000,000. 
 Section 12.6. Resignation by Trustee. The Trustee and any successor trustee may at any time resign from the trusts hereby created by giving thirty (30) days written notice to the Issuer, the Company,
and the Credit Provider, and such resignation shall take effect at the end of such thirty (30) days (provided a successor trustee has been duly appointed) or upon the earlier appointment of a successor trustee by the Bondholders or by the
Issuer. Such notice may be served personally or sent by registered mail. Any such resignation shall not take effect until the appointment of a successor trustee and the acceptance of such appointment. 
  

 66 







 Section 12.7. Removal of Trustee. The Trustee may be removed at any time
by an instrument or concurrent instruments in writing delivered to the Trustee and to the Issuer, signed by the Owners of a majority in aggregate principal amount of Bonds outstanding hereunder, and with the prior written consent of the Credit
Provider (if the Credit Enhancement shall be in effect and there shall not have occurred and be continuing a Credit Provider Failure). The Trustee may be removed at any time by the Issuer if directed by the Company, provided there does not exist an
Event of Default at such time resulting from any act or omission by the Company. The Trustee may be removed at any time by the Issuer if directed by the Bank, provided there does not exist an Event of Default at such time resulting from a Credit
Provider Failure or Liquidity Provider Failure. Any such removal shall not take effect until the appointment of a successor trustee and the acceptance of such appointment. 
 Section 12.8. Appointment of Successor Trustee. In case the Trustee hereunder shall resign or be removed, or be
dissolved, or shall be in course of dissolution or liquidation, or otherwise become incapable of acting hereunder, or in case it shall be taken under the control of any public officer or officers, or of a receiver appointed by the court, a successor
may be appointed by the Issuer, as directed by the Company (so long as no Event of Default has occurred and is continuing) with the prior written consent of the Credit Provider (if the Credit Enhancement shall be in effect and there shall not have
occurred and be continuing a Credit Provider Failure), by an instrument executed and signed by its Mayor and attested by its Clerk under its seal, or by the Owners of a majority in aggregate principal amount of Bonds outstanding hereunder (if an
Event of Default has occurred and is continuing), by an instrument or concurrent instruments in writing signed by such Owners, or by their attorneys in fact, duly authorized; provided, nevertheless, that if within thirty (30) days of the
resignation, removal or dissolution of the Trustee hereunder the Issuer or the Owners, as the case may be, fail to so appoint a successor to fill such vacancy, the Trustee may apply to a court of competent jurisdiction which shall have authority to
appoint a temporary trustee until a successor trustee shall be appointed by the Issuer or the Bondholders in the manner above provided. Any such temporary trustee so appointed by a court of competent jurisdiction shall immediately and without
further act be superseded by the trustee so appointed by the Issuer or such Bondholders. Every such temporary trustee and every such successor trustee shall be a bank with trust powers or a trust company in good standing, having capital and surplus
of not less than $50,000,000, and shall be satisfactory to the Company so long as there is no termination of the interest of the Company by virtue of an Event of Default or otherwise. 
 Section 12.9. Concerning Any Successor Trustee. Every successor or temporary trustee appointed hereunder shall
execute, acknowledge and deliver to its predecessor and also to the Issuer an instrument in writing accepting such appointment hereunder, and thereupon such successor or temporary trustee, without any further act or conveyance, shall become fully
vested with all the estates, properties, rights, powers, trusts, duties and obligations of its predecessor; but such predecessor shall, nevertheless, on the written request of the Issuer or of its successor trustee, execute and deliver an instrument
transferring to such successor all the estate, properties, 

  

 67 







 
rights, powers and trusts of such predecessor hereunder; and every predecessor trustee shall deliver all securities, moneys and any other property held by it
as trustee hereunder to its successor. Should any instrument in writing from the Issuer be required by any successor trustee for more fully and certainly vesting in such successor the estates, rights, powers and duties hereby vested or intended to
be vested in the predecessor trustee, any and all such instruments in writing shall, on request, be executed, acknowledged and delivered by the Issuer. The resignation of any trustee and the instrument or instruments removing any trustee and
appointing a successor hereunder, together with all other instruments provided for in this Article shall, at the expense of the Issuer, be forthwith filed and/or recorded by the successor trustee in each recording office where the Indenture shall
have been filed and/or recorded. 
 Section 12.10. Reliance Upon Instruments. The resolutions, opinions,
certificates and other instruments provided for in this Indenture may be accepted and relied upon by the Trustee as conclusive evidence of the facts and conclusions stated therein and shall be full warrant, protection and authority to the Trustee
for its actions taken hereunder. 
 Section 12.11. Appointment of Co-Trustee. The Issuer and the Trustee
shall have power to appoint and upon the request of the Trustee the Issuer shall for such purpose join with the Trustee in the execution of all instruments necessary or proper to appoint another corporation or one or more persons approved by the
Trustee, and satisfactory to the Company (so long as no Event of Default has occurred and is continuing) and the Credit Provider (if the Credit Enhancement shall be in effect and there shall not have occurred and be continuing a Credit Provider
Failure), either to act as co-trustee or co-trustees jointly with the Trustee of all or any of the property subject to the lien hereof, or to act as separate trustee or trustee of all or any such property, with such powers as may be provided in the
instrument of appointment and to vest in such corporation or person or persons as such separate trustee or co-trustee any property, title, right or power deemed necessary or desirable. In the event that the Issuer shall not have joined in such
appointment within fifteen (15) days after the receipt by it of a request so to do, the Trustee alone shall have the power to make such appointment. Should any deed, conveyance or instrument in writing from the Issuer be required by separate
trustee or co-trustee so appointed for more fully and certainly vesting in and confirming to him or to it 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. Every such co-trustee and separate trustee shall, to the extent permitted by law, be appointed subject to the following provisions and conditions, namely: 
 (a) The Bonds shall be authenticated and delivered, and all powers, duties, obligations and rights conferred upon the Trustee in respect
of the custody of all money and securities pledged or deposited hereunder, shall be exercised solely by the Trustee; and 
 (b) The Trustee, at any time by an instrument in writing, may remove any such separate Trustee or co-trustee. 
  

 68 







 Every instrument, other than this Indenture, appointing any such co-trustee or separate trustee, shall
refer to this Indenture and the conditions of this Article XII expressed, and upon the acceptance in writing by such separate trustee or co-trustee, he, they or it shall be vested with the estate or property specified in such instrument, jointly
with the Trustee (except insofar as local law makes it necessary for any separate trustee to act alone), subject to all the trusts, conditions and provisions of this Indenture. Any such separate trustee or co-trustee may at any time, by an
instrument in writing, constitute the Trustee as his, their or its agent or attorney-in-fact with full power and authority, to the extent authorized by law, to do all acts and things and exercise all discretion authorized or permitted by him, them
or it, for and on behalf of him, them or it and in his, their or its name. In case any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all the estate, properties, rights, powers, trusts, duties and
obligations of said separate trustee or co-trustee shall vest in and be exercised by the Trustee until the appointment of a new trustee or a successor to such separate trustee or co-trustee. 
 Section 12.12. Designation and Succession of Paying Agents. The Trustee shall be the initial Paying
Agent for the Bonds, and the Trustee and any other commercial banks with trust powers or any trust companies designated as Paying Agent or Paying Agents in any supplemental indenture or in an instrument appointing a successor Trustee, shall be the
Paying Agent or Paying Agents for the Bonds. 
 Any commercial bank with trust powers or any trust company with which or into which any
Paying Agent may be merged or consolidated, or to which the assets and business of such Paying Agent may be sold, shall be deemed the successor of such Paying Agent for the purposes of this Indenture. If the position of Paying Agent shall become
vacant for any reason, the Issuer shall, within thirty (30) days thereafter, appoint such bank or trust company as shall be specified as such Paying Agent by the Company, with the prior written consent of the Credit Provider (if the Credit
Enhancement shall be in effect and there shall not have occurred and be continuing a Credit Provider Failure), to fill such vacancy; provided, however, that, if the Issuer shall fail to appoint such Paying Agent within said period, the Trustee shall
make such appointment. Any resignation or removal of a Paying Agent shall not take effect until the appointment of a successor paying agent and the acceptance of such appointment. 
 The Paying Agents shall enjoy the same protective provisions in the performance of their duties hereunder as are specified in Section 12.1 hereof
with respect to the Trustee insofar as such provisions may be applicable. 
 Section 12.13. Designation and
Succession of Tender Agents. The Trustee shall be the initial Tender Agent for the Bonds, and the Trustee and any other commercial banks with trust powers or any trust companies designated as Tender Agent or Tender Agents
in any supplemental indenture or in an instrument appointing a successor Trustee, shall be the Tender Agent or Tender Agents for the Bonds. 
  

 69 







 Any commercial bank with trust powers or any trust company with which or into which any Tender Agent may
be merged or consolidated, or to which the assets and business of such Tender Agent may be sold, shall be deemed the successor of such Tender Agent for the purposes of this Indenture. If the position of Tender Agent shall become vacant for any
reason, the Issuer shall, within thirty (30) days thereafter, appoint such bank or trust company as shall be specified as such Tender Agent by the Company, with the prior written consent of the Credit Provider (if the Credit Enhancement shall
be in effect and there shall not have occurred and be continuing a Credit Provider Failure), to fill such vacancy; provided, however, that, if the Issuer shall fail to appoint such Tender Agent within said period, the Trustee shall make such
appointment. Any resignation or removal of a Tender Agent shall not take effect until the appointment of a successor tender agent and the acceptance of such appointment. 
 The Tender Agents shall enjoy the same protective provisions in the performance of their duties hereunder as are specified in Section 12.1 hereof with respect to the Trustee insofar as such provisions may be
applicable. 
  

 70 







 ARTICLE XIII 
 REMARKETING AGENT 
 Section 13.1. Appointment of Remarketing
Agent. (a) The Remarketing Agent shall be appointed pursuant to the Remarketing Agreement to remarket Bonds pursuant to this Indenture and perform the other duties of the Remarketing Agent described hereunder, and to 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 Notice Parties at all reasonable times. The Remarketing Agent shall act as such under the Remarketing Agreement.

 (b) The Remarketing Agent may at any time resign and be discharged of the duties and obligations created by this Indenture as set forth in
the Remarketing Agreement. The Remarketing Agent may suspend its remarketing efforts as set forth in the Remarketing Agreement. The Remarketing Agent may be removed at any time, at the direction of the Company as set forth in the Remarketing
Agreement. Any successor Remarketing Agent shall be selected by the Company, and shall be a member of the National Association of Securities Dealers, Inc., shall have a capitalization of at least fifteen million dollars ($15,000,000), shall be
authorized by law to perform all the duties set forth in this Indenture and shall be acceptable to the Credit Provider and Liquidity Provider. The Company’s delivery to the Trustee of a certificate setting forth the effective date of the
appointment of a successor Remarketing Agent and the name of such successor shall be conclusive evidence that (i) if applicable, the predecessor Remarketing Agent has been removed in accordance with the provisions of this Indenture and
(ii) such successor has been appointed and is qualified to act as Remarketing Agent under the terms of this Indenture. 
 (c) If the
Remarketing Agent consolidates with, merges or converts into, or transfers all or substantially all of its assets (or, in the case of a bank, national banking association or trust company, its corporate assets) to, another corporation, the
resulting, surviving or transferee corporation without any further act shall be the successor Remarketing Agent. 
  

 71 







 ARTICLE XIV 
 SUPPLEMENTAL INDENTURES 
 Section 14.1. Supplemental Indentures

more of the following purposes: 
 (i) To cure any formal defect, omission, inconsistency or ambiguity in this Indenture;

 (ii) To grant to or confer or impose upon the Trustee for the benefit of the Bondholders any additional rights, remedies,

shall be imposed upon the Trustee without its consent; 
 (iii) To add to the covenants and agreements of, and limitations and
restrictions upon, the Issuer in this Indenture other covenants, agreements, limitations and restrictions to be observed by the Issuer which are not contrary to or inconsistent with this Indenture as theretofore in effect; 
 (iv) To confirm, as further assurance, any pledge under, and the subjection to any claim, lien or pledge created or to be created by, this
Indenture, of the Revenues of the Issuer from the Loan Agreement or of any other moneys, securities or funds; 
 (v) To comply
with the requirements of the Trust Indenture Act of 1939, as from time to amended; 
 (vi) To modify, alter, amend or
supplement this Indenture in any other respect which is not materially adverse to the Bondholders and which does not involve a change described in clause (a), (b), (c), (d), (e) or (f) of Section 14.2 hereof and which, in the judgment
of the Trustee, is not to the prejudice of the Trustee; 
 (vii) To effect any change required in connection with the rating
of the Bonds; 
  

 72 







 (viii) To make any other change or amendment hereto which the Trustee determines does not
materially adversely affect the interests of any Owner or the Trustee; 
 (ix) To provide for the refunding of any Bonds,
including the right to establish and administer an escrow fund and to take related action in connection therewith; 
 (x) To
make changes or modifications necessary to enter into an Alternate Credit Enhancement or Alternate Liquidity Facility, including, without limitation, adding additional Events of Default relating to the Alternate Credit Enhancement or Alternate

 (xi) To make any changes
or modifications on any Mandatory Purchase Date. 
 (b) The Issuer and the Trustee may, from time to time and at any time during the Daily
Mode and the Weekly Mode, without the consent of the Bondholders, enter into supplemental indentures for any purpose, provided that (i) notice of such amendment shall be given by first class mail to each Owner of Bonds at least thirty
(30) days prior to the effective date of such amendment, and (ii) such notice shall advise that the Bondholders have the option to tender their Bonds as provided in Section 4.1 hereof. 
 Section 14.2. Supplemental Indentures Requiring Consent of Bondholders. Subject to the terms and
provisions contained in this Section, and not otherwise, the Owners of not less than a majority in aggregate principal amount of the Bonds then outstanding shall have the right, from time to time, anything contained in this Indenture to the contrary
notwithstanding to consent to and approve the execution by the Issuer and the Trustee of such indenture or indentures supplemental hereto as shall be deemed necessary and desirable by the Issuer for the purpose of modifying, altering, amending,
adding to or rescinding, in any particular, any of the terms or provisions contained in this Indenture or in any supplemental indenture; provided, however, that nothing herein contained shall permit, or be construed as permitting, without the
consent and approval of the Owners of all of the Bonds then outstanding which are adversely affected thereby (a) an extension of the maturity (or mandatory redemption date) of the principal of or the interest on any Bond issued hereunder, or
(b) a reduction in the principal amount of or rate of interest on any Bond issued hereunder, or (c) the creation of any lien ranking prior to or on a parity with the lien of this Indenture on the Trust Estate or any part thereof, except as

 73 







 
supplemental indenture, or (f) deprive the Owner of any Bond then outstanding of the lien hereby created on the Trust Estate. Nothing herein contained,
however, shall be construed as making necessary the approval of Bondholders of the execution of any supplemental indenture as provided in Section 14.1 of this Article. 
 If, at any time the Issuer shall request the Trustee to enter into any supplemental indenture for any of the purposes of this Section, the Trustee shall,
at the expense of the Issuer, cause notice of the proposed execution of such supplemental indenture to be mailed by first class mail to each registered owner of the Bonds and the Credit Provider. Such notice shall briefly set forth the nature of the
proposed supplemental indenture and shall state that copies thereof are on file at the principal office of the Trustee for inspection by Bondholders. The Trustee shall not, however, be subject to any liability to any Bondholder by reason of its
failure to mail such notice, and any such failure shall not affect the validity of such supplemental indenture when consented to and approved as provided in this Section. If the Owners of not less than two-thirds (2/3) in aggregate principal
amount of the Bonds outstanding at the time of the execution of any such supplemental indenture shall have consented to and approved the execution thereof as herein provided, no Owner of any Bond shall have any right to object to any of the terms
and provisions contained therein, or the operation thereof, or in any manner to question the propriety of the execution thereof, or to enjoin or restrain the Trustee or the Issuer from executing the same or from taking any action pursuant to the
provisions thereof. Upon the execution of any such supplemental indenture, this Indenture shall be deemed to be modified and amended in accordance therewith. 
 Section 14.3. Consent of Company. Anything herein to the contrary notwithstanding and provided the Company shall not be in default under the Loan Agreement, a supplemental indenture
under this Article XIV shall not become effective unless and until the Company shall have consented to the execution and delivery of such supplemental indenture. In this regard, the Trustee shall cause notice of the proposed execution and delivery
of any such supplemental indenture together with a copy of the proposed supplemental indenture to be mailed by certified or registered mail to the Company at least fifteen (15) days prior to the proposed date of execution and delivery of any
such supplemental indenture. The Company shall be deemed to have consented to the execution and delivery of any such supplemental indenture if the Trustee receives a letter or other instrument signed by an authorized officer of the Company
expressing consent. 
 Section 14.4. Consent of Credit Provider. Anything herein to the contrary
notwithstanding and provided the Credit Enhancement shall be in effect and there shall not have occurred and be continuing a Credit Provider Failure, a supplemental indenture under this Article XIV shall not become effective unless and until the
Credit Provider shall have consented to the execution and delivery of such supplemental indenture or shall have advised the Trustee in writing that no such consent is required under the Reimbursement Agreement.

 Section 14.5. Credit Provider Deemed Owner of
Bonds. Except as hereinafter set forth, for all purposes of obtaining the consent of Bondholders under this Article XIV, the Credit Provider shall, so long as the Credit Enhancement shall be in effect and there shall not have occurred and be
continuing a Credit Provider Failure, be deemed the Owner of all Bonds. As such, the Credit Provider may take all actions permitted by this Article XIV to be taken by the Owners of the Bonds, to the exclusion of the actual Owners of the Bonds;
provided, however, the provisions of this Section 14.5 shall not apply to any supplemental indenture requiring the consent and approval of the Owners of all of the Bonds then Outstanding which are adversely affected thereby, including, without
limitation, any change described in clause (a), (b), (c), (d), (e) or (f) of Section 14.2 hereof.

 ARTICLE XV 
 AMENDMENT TO LOAN AGREEMENT 
 Section 15.1. Amendments Not
Requiring Consent of Bondholders. The Trustee may from time to time, and at any time, consent to any amendment, change or modification of this Loan Agreement for (i) any purpose for which a supplemental indenture may
be approved pursuant to Section 14.1 hereof, (ii) the purpose of curing any ambiguity or formal defect or omission, or (iii) making any other change therein which in the reasonable judgment of the Trustee is not to the prejudice of
the Trustee or the Owners of the Bonds. The Trustee shall not consent to any other amendment, change or modification of the Loan Agreement without the approval or consent of the Owners of not less than a majority in aggregate principal amount of the
Bonds at the time outstanding, evidenced in the manner provided in Section 16.1 hereof. 
 Section 15.2. Amendments
Requiring Consent of Bondholders. If at any time the Issuer or the Company shall request the Trustee’s consent to a proposed amendment, change or modification requiring Bondholder approval under Section 15.1,
the Trustee, shall, at the expense of the requesting party, cause notice of such proposed amendment, change or modification to be mailed in the same manner as provided by Section 14.2 hereof with respect to supplemental indentures. Such notice
shall briefly set forth the nature of such proposed amendment, change or modification and shall state that copies of the instrument embodying the same are on file in the principal office of the Trustee for inspection by any interested Bondholder.
The Trustee shall not, however, be subject to any liability to any Bondholder by reason of its failure to publish or mail such notice, and any such failure shall not affect the validity of such amendment, change or modification when consented to by
the Trustee in the manner hereinabove provided. 
 Section 15.3. Credit Provider Deemed Owner
of Bonds. Except as hereinafter set forth, for all purposes of obtaining the consent of Bondholders under this Article XV, the Credit Provider shall, so long as the Credit Enhancement shall be in effect and there shall not have
occurred and be continuing a Credit Provider Failure, be deemed the Owner of all Bonds. As such, the Credit Provider may take all actions permitted by this Article XV to be taken by the Owners of the Bonds, to the exclusion of the actual Owners of
the Bonds; provided, however, the provisions of this Section 15.3 shall not apply to any amendment, change or modification of this Loan Agreement which corresponds to supplemental indentures that contain provisions requiring the consent and
approval of the Owners of all of the Bonds then Outstanding which are adversely affected thereby as described in Section 14.5 hereof.

 78 







 Section 16.5. Severability. If any provisions of this Indenture shall be held or
deemed to be or shall, in fact, be inoperative or unenforceable as applied in any particular case in any jurisdiction or jurisdictions or in all jurisdictions or in all cases because it conflicts with any provisions or any constitution or statute or
rule of public policy, or for any other reason, such circumstances shall not have the effect of rendering the provision in question inoperative or unenforceable in any other case or circumstance, or of rendering any other provision or provisions
herein contained invalid, inoperative or unenforceable to any extent whatever. 
 The invalidity of any one or more phrases, sentences,
clauses or paragraphs in this Indenture contained shall not affect the remaining portions of this Indenture or any part thereof. 
 Section 16.6. Applicable Provisions of Law. This Indenture shall be considered to have been executed in the State of Arkansas and it is the intention of the parties that the substantive law of the
State of Arkansas govern as to all questions of interpretation, validity and effect. 
 Section 16.7. Counterparts. This
Indenture may be executed in several counterparts, each of which shall be an original and all of which shall constitute but one and the same instrument. 
 Section 16.8. Successors and Assigns. All the covenants, stipulations, provisions, agreements, rights, remedies and claims of the parties hereto in this Indenture contained shall bind
and inure to the benefit of their successors and assigns.

are for convenience only and in no way define, limit or describe the scope or intent of any provisions or sections of this Indenture. 
 Section 16.10. Bonds Owned by the Issuer or the Company. In determining whether Bondholders of the requisite aggregate principal amount of the Bonds have concurred in any
direction, consent or waiver under this Indenture, Bonds which are owned by the Issuer or the Company or by any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company (unless the
Company or any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company shall own not less than 100% in aggregate principal amount of the Bonds then outstanding) shall be disregarded and
deemed not to be outstanding for the purpose of any such determination, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Bonds which the Trustee knows are so
owned shall be so disregarded. Bonds so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Bonds and that
the pledgee is not the Issuer or the Company or any person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company. In case of a dispute as to such right, any decision by the Trustee taken upon
the advice of counsel shall be full protection to the Trustee. 
  

 79 







 Section 16.11. Holidays. When the date on which principal of or interest or premium on
any Bond is due and payable is not a Business Day, payment may be made on Bonds presented at the place of payment on the next ensuing Business Day with effect as though payment were made on the due date, and, if such payment is made, no additional
interest shall accrue from and after such due date. When any other action is provided herein to be done on a day named or within a time period named, and the day or the last day of the period falls on a day other than a Business Day, it may be
performed on the next ensuing Business Day with effect as though performed on the appointed day or within the specified period.

 KNOW ALL
MEN BY THESE PRESENTS: 
 That the City of Osceola, Arkansas, a municipality organized and existing under the laws of the State of Arkansas
(the “Issuer”), for value received, promises to pay to the Registered Owner shown above, or registered assigns, but solely from the source and in the manner hereinafter set forth, the Principal Amount shown above on the Maturity Date shown
above, and in like manner to pay interest on said Principal Amount until payment of such Principal Amount has been made or duly provided for, except as the provisions hereinafter set forth with respect to redemption of this Bond prior to maturity
may become applicable hereto. Interest on this Bond shall be payable at the interest rate per annum shown above through                     ,
and thereafter the interest rate will be determined as provided in the Trust Indenture dated as of April 1, 2006 (the “Indenture”), duly executed and delivered by the Issuer to Regions Bank, Little Rock, Arkansas, or its successor or
successors, as Trustee (the “Trustee”). This Bond shall bear interest from its Dated Date shown above or from the most recent Interest Payment Date to which interest has been paid or duly provided for. The principal and Redemption Price
(as defined in the Indenture) on this Bond are payable in lawful money of the United States of America upon the presentation and surrender hereof at the principal corporate trust office of the Trustee, and interest on this Bond is payable in like
money to the Registered Owner hereof by check or draft drawn upon the Trustee and mailed or, in certain circumstances described in the Indenture, by wire transfer to the person in whose name this Bond is registered at the close of business on the
Record Date (as defined in the Indenture) at his address as it appears on the bond registration books of the Issuer kept by the Trustee.

 This Bond is one of a series of Bonds in the aggregate principal amount of $100,000,000 (the
“Bonds”), issued for the purpose of financing the cost of acquiring, constructing and equipping an undivided interest in certain sewage and solid waste disposal facilities at the Plum Point Energy Station located within or near the Issuer
(the “Project”), for use by Plum Point Energy Associates, LLC, a Delaware limited liability company (the “Company”), and paying a portion of the expenses of issuing the Bonds. The Bonds are all issued under and are all equally
and ratably secured and entitled to the protection given by the Indenture. Reference is hereby made to the Indenture and all indentures supplemental thereto for the provisions, among others, with respect to the nature and extent of the security, the
rights, duties and obligations of the Issuer, the Trustee and the registered owners of the Bonds, and the terms upon which the Bonds are issued and secured. Capitalized terms used herein and not otherwise defined shall have the respective meanings
assigned them in the Indenture. The terms and conditions of the financing of the Project, the use of the proceeds of the Bonds by the Company for such purpose, and the payment of certain amounts thereunder, are contained a Loan Agreement dated as of
April 1, 2006 (the “Loan Agreement”), by and between the Issuer and the Company. 
 The Bonds are issued pursuant to and in
full compliance with the laws of the State of Arkansas, particularly Title 14, Chapter 267 of the Arkansas Code of 1987 Annotated (the “Act”), and pursuant to ordinances of the Issuer, which authorized the execution and delivery of the
Indenture. The Bonds and the interest thereon do not constitute an indebtedness of the Issuer within the meaning of any constitutional or statutory limitation. 
 The Bonds are not general obligations of the Issuer but are special obligations payable solely from revenues derived from the Loan Agreement. The Loan Agreement provides for payments by the Company in amounts
sufficient to provide for the payment of the principal of and interest on the Bonds as due and payable. Provision has been made in the Loan Agreement for such payments to be paid directly to the Trustee and deposited in a special account of the
Issuer designated “Solid Waste Disposal Revenue Bond Fund - Plum Point Energy Associates, LLC Project,” and such payments have been duly assigned to the Trustee for that purpose. All the rights and interest of the Issuer in and to the Loan
Agreement (except for certain rights specified in the Indenture) have been assigned under the Indenture to the Trustee to secure the payment of the principal of and interest on the Bonds. In addition, the Company has caused to be delivered to the
Trustee an irrevocable letter of credit (the “Credit Enhancement”) of Credit Suisse, New York Branch (the “Credit Provider”), in favor of the Trustee for the benefit of the owners of the Bonds to support, to the extent provided
in the Credit Enhancement, the payment of the principal of and interest on the Bonds on or prior to April 26, 2007. The Company may, at its election, cause the Credit Provider to provide one or more extensions of the Credit Enhancement or
provide at any time for the delivery to the Trustee of Alternate Credit Enhancement, in each case in accordance with the provisions of the Indenture. Failure to secure an extension of the Credit Enhancement then in effect shall result in mandatory
purchase of the Bonds as provided in the Indenture. 
  

 83 







 The Bonds shall bear interest in the Daily Mode, the Weekly Mode, the Flexible Mode, the Term Rate Mode,
or the Fixed Rate Mode, as provided in the Indenture and as set forth on the face hereof. This Bond initially shall bear interest at a per annum rate listed above until May 3, 2006 (the “Initial Rate Period”), and thereafter in the
Weekly Mode until converted to a different Mode in accordance with the provisions of the Indenture. Interest accrued on the Bonds shall be payable in arrears on each Interest Payment Date. Interest on the Bonds in the Daily Mode, the Weekly Mode, or
the Flexible Mode shall be calculated on the basis of a 365/366 day year for the actual number of days elapsed (except during the Initial Rate Period, when interest shall accrue on the basis of a 360-day comprised of twelve 30-day months). Interest
on the Bonds in the Term Rate Mode or the Fixed rate Mode shall be calculated on the basis of a 360 day year comprised of twelve 30-day months. This Bond may be converted from the Weekly Mode to a Daily Mode, Flexible Mode, Term Rate Mode, or Fixed
Mode, upon such notice and conditions as described in the Indenture. 
 The Issuer has appointed Goldman, Sachs & Co. as Remarketing
Agent under the Indenture. The Remarketing Agent may from time to time, at the direction of the Company, be removed or replaced. 
 The owner
of this Bond shall have no right to enforce the provisions of the Indenture or to institute action to enforce the covenants therein, or to take any action with respect to any event of default under the Indenture, or to institute, appear in and
defend any suit or other proceeding with respect thereto, except as provided in the Indenture. In certain events, on the conditions, in the manner and with the effect set forth in the Indenture, the principal of this Bond may be declared and may
become due and payable before the stated maturity thereof, together with accrued interest thereon. 
 Modifications or alterations of the
Indenture, or of any indenture supplemental thereto, may be made only to the extent and in the circumstances permitted by the Indenture. 
 The Bonds are subject to optional and mandatory redemption prior to their stated maturity and to optional tender and mandatory tender for purchase, all as provided in the Indenture. 
 In the event any of the Bonds or portions thereof are called for redemption, notice thereof shall be given by the Trustee in the manner set forth in the
Indenture; provided, however, that failure to give such notice by mailing, or any defect therein, shall not affect the validity of the proceedings for the redemption of any Bond with respect to which no such failure or defect has occurred. Each
notice shall identify the Bonds or portions thereof being called and shall state, among other things, the redemption date, the redemption price, and whether the notice is 

  

 84 







 
conditional as described below. After the date specified in such call, the Bond or Bonds so called will cease to bear interest provided funds sufficient for
their redemption have been deposited with the Trustee, and, except for the purpose of payment, shall no longer be protected by the Indenture and shall not be deemed to be outstanding under the provisions of the Indenture. 
 Any notice of optional redemption may state that the redemption is conditioned on the Trustee’s receipt of moneys for such redemption on or prior to
the opening of business on the redemption date. If such moneys are not so received, the redemption of the Bonds for which notice was given will not be made. If such redemption is not effectuated, the Trustee will, within five (5) days
thereafter, give notice in the manner in which the notice of redemption was given that such moneys were not so received. 
 This Bond may be
transferred on the books of registration kept by the Trustee by the registered owner or by his duly authorized attorney upon surrender hereof, together with a written instrument of transfer duly executed by the registered owner or his duly
authorized attorney. Every transferee shall take this Bond subject to all payments and prepayments of principal and interest (as reflected by the payment record maintained by the Trustee) prior to such transfer. 
 The Bonds are issuable as registered Bonds without coupons in denominations of (i) $100,000 and any integral multiple of $5,000 in excess thereof
with respect to Bonds in a Daily Mode or Weekly Mode, (ii) $100,000 and any integral multiple of $1,000 in excess thereof with respect to Bonds in a Flexible Mode, and (iii) $5,000 and any integral multiple thereof with respect to Bonds in
a Long-Term Mode. Subject to the limitations and upon payment of the charges provided in the Indenture, Bonds may be exchanged for a like aggregate principal amount of Bonds of other Authorized Denominations and in the same Mode. 
 This Bond is issued with the intent that the laws of the State of Arkansas will govern its construction. 
 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
issuance of the Bonds do exist, have happened and have been performed in due time, form and manner as required by law; that the indebtedness represented by the Bonds, together with all obligations of the Issuer, does not exceed any constitutional or
statutory limitation; and that the above referred to revenues pledged to the payment of the principal of and interest on the Bonds as the same become due and payable will be sufficient in amount for that purpose. 
 This Bond shall not be valid or become obligatory for any purpose or be entitled to any security or benefit under the Indenture until the Certificate of
Authentication hereon shall have been signed by the Trustee. 
  

 85 







 IN WITNESS WHEREOF, the City of Osceola, Arkansas has caused this Bond to be executed by its Mayor and
