The Environmental Control Bonds

SECTION 2.01. Form. The Environmental Control Bonds and the Indenture Trustee’s certificate of authentication shall be in substantially the forms set forth in Exhibit A to the applicable Series Supplement, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Indenture or by the related Series Supplement and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may, consistently herewith, be determined by the Authorized Officer of the Issuer executing such Environmental Control Bonds, as evidenced by his or her execution of such Environmental Control Bonds. Any portion of the text of any Environmental Control Bond may be set forth on the reverse thereof, with an appropriate reference thereto on the face of the Environmental Control Bond. Each Environmental Control Bond shall be dated the date of its authentication.

The Environmental Control Bonds shall be typewritten, printed, lithographed or engraved or produced by any combination of these methods (with or without steel engraved borders), all as determined by the Authorized Officer of the Issuer executing such Environmental Control Bonds, as evidenced by his or her execution of such Environmental Control Bonds.

Each Environmental Control Bond shall bear upon its face the designation so selected for the Series or Tranche to which it belongs. The terms of all Environmental Control Bonds of the same Series shall be the same, unless such Series is comprised of one or more Tranches, in which case the terms of all Environmental Control Bonds of the same Tranche shall be the same.

Each Environmental Control Bond shall state that the Statute provides that the State of West Virginia pledges to and agrees with the Environmental Control Bondholders that the State of West Virginia will not take or permit any action that impairs the value of the Environmental Control Property or , except as allowed under subsection (e) of ▇.▇▇ Code §24-2-4e, reduce, alter or impair Environmental Control Charges that are imposed, collected and remitted for the benefit of the Environmental Control Bondholders until any principal, interest and premium, if any, in respect of the Environmental Control Bonds, all financing costs and all amounts to be paid to any assignee or financing party under an ancillary agreement are paid or performed in full.

Environmental Control Bonds bearing the manual or facsimile signature of an individual who was at any time an Authorized Officer of the Issuer shall bind the Issuer, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Environmental Control Bonds or did not hold such offices at the date of such Environmental Control Bonds.

At any time and from time to time after the execution and delivery of this Indenture, the Issuer may deliver Environmental Control Bonds executed on behalf of the Issuer to the Indenture Trustee pursuant to an Issuer Order for authentication; and the Indenture Trustee shall authenticate and deliver such Environmental Control Bond as in this Indenture and in such Issuer Order provided and not otherwise.

No Environmental Control Bond shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Environmental Control Bond a certificate of authentication substantially in the form provided for in the related Series Supplement executed by the Indenture Trustee by the manual signature of one of its authorized signatories, and such certificate upon any Environmental Control Bond shall be conclusive evidence, and the only evidence, that such Environmental Control Bond has been duly authenticated and delivered hereunder.

SECTION 2.03. Denominations; Environmental Control Bonds Issuable in Series. The Environmental Control Bonds of each Series shall be issuable as registered Environmental Control Bonds in the Authorized Initial Denominations specified in the Series Supplement therefor.

The Environmental Control Bonds may, at the election of and as authorized by an Authorized Officer of the Issuer, and set forth in a Series Supplement, be issued in one or more Series (each of which may be comprised of one or more Tranches), and shall be designated generally as the “Environmental Control Bonds” of the Issuer, with such further particular designations added or incorporated in such title for the Environmental Control Bonds of any particular Series or Tranche as an Authorized Officer of the Issuer may determine and be set forth in the Series Supplement therefor.

Each Series of Environmental Control Bonds shall be created by a Series Supplement authorized by an Authorized Officer of the Issuer and establishing the terms and provisions of such Series. The several Series and Tranches thereof may differ as between Series and Tranches, in respect of any of the following matters:

(i) designation of the Series and, if applicable, the Tranches thereof;

(ii) the aggregate principal amount of the Environmental Control Bonds of the Series and, if applicable, each Tranche thereof;

(iii) the Bond Rate of the Series and, if applicable, each Tranche thereof or the formula, if any, used to calculate the applicable Bond Rate or Bond Rates for the Series;

(iv) the Payment Dates for the Series and each Tranche thereof;

(v) the Expected Final Payment Date of the Series, and, if applicable, each Tranche thereof;

(vi) the Series Termination Date for the Series and, if applicable, the Tranche Termination Dates for each Tranche thereof;

(vii) the Series Issuance Date for the Series;

(viii) the place or places for payments with respect to the Series;

(ix) the Authorized Initial Denominations for the Series;

(x) the Expected Sinking Fund Schedule for the Series;

(xi) the Required Capital Amount;

(xii) the Calculation Dates and True-Up Adjustment Dates for the Series;

(xiii) the credit enhancement, if any, applicable to the Series and each Tranche thereof and, with respect to Floating Rate Bonds, the terms of the applicable Swap Agreement and the identity of the Swap Counterparty; and

(xiv) any other terms of the Series or Tranche that are not inconsistent with the provisions of this Indenture.

SECTION 2.04. Temporary Environmental Control Bonds. Pending the preparation of Definitive Environmental Control Bonds, or by agreement of the purchasers of all Environmental Control Bonds, the Issuer may execute, and upon receipt of an Issuer Order the Indenture Trustee shall authenticate and deliver, temporary Environmental Control Bonds which are printed, lithographed, typewritten, mimeographed or otherwise produced, of the tenor of the Definitive Environmental Control Bonds in lieu of which they are issued and with such variations not inconsistent with the terms of this Indenture and the related Series Supplement as the Authorized Officer of the Issuer executing such Environmental Control Bonds may determine, as evidenced by his or her execution of such Environmental Control Bonds.

If temporary Environmental Control Bonds are issued, the Issuer will cause Definitive Environmental Control Bonds to be prepared without unreasonable delay. After the preparation of Definitive Environmental Control Bonds, the temporary Environmental Control Bonds shall be exchangeable for Definitive Environmental Control Bonds upon surrender of the temporary Environmental Control Bonds at the office or agency of the Issuer to be maintained as provided in Section 3.02, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Environmental Control Bonds, the Issuer shall execute and the Indenture Trustee shall authenticate and deliver in exchange therefor a like initial principal amount of Definitive Environmental Control Bonds in Authorized Initial Denominations. Until so exchanged, the temporary Environmental Control Bonds shall in all respects be entitled to the same benefits under this Indenture as Definitive Environmental Control Bonds.

SECTION 2.05. Registration; Registration of Transfer and Exchange. The Issuer shall cause to be kept a register (the “Bond Register”) in which, subject to such reasonable regulations as it may prescribe, the Issuer shall provide for the registration of Environmental Control Bonds and the registration of transfers of Environmental Control Bonds. The Indenture Trustee shall be the “Bond Registrar” for the purpose of registering Environmental Control Bonds and transfers of Environmental Control Bonds as herein provided. Upon any resignation

of any Bond Registrar, the Issuer shall promptly appoint a successor or, if it elects not to make such an appointment, assume the duties of Bond Registrar.

If a Person other than the Indenture Trustee is appointed by the Issuer as Bond Registrar, the Issuer shall give the Indenture Trustee prompt written notice of the appointment of such Bond Registrar and of the location, and any change in the location, of the Bond Register, and the Indenture Trustee shall have the right to inspect the Bond Register at all reasonable times and to obtain copies thereof, and the Indenture Trustee shall have the right to conclusively rely upon a certificate executed on behalf of the Bond Registrar by an Authorized Officer as to the names and addresses of the Holders of the Environmental Control Bonds and the original and Outstanding principal amounts and number of such Environmental Control Bonds.

Upon surrender for registration of transfer of any Environmental Control Bond at the office or agency of the Issuer to be maintained as provided in Section 3.02, an Authorized Officer shall execute, and the Indenture Trustee shall authenticate and the Environmental Control Bondholder shall obtain from the Indenture Trustee, in the name of the designated transferee or transferees, one or more new Environmental Control Bonds in any Authorized Initial Denominations, of a like Series (and, if applicable, Tranche) and aggregate initial principal amount.

At the option of the Holder, Environmental Control Bonds may be exchanged for other Environmental Control Bonds of a like Series (and, if applicable, Tranche) and aggregate initial principal amount in Authorized Initial Denominations, upon surrender of the Environmental Control Bonds to be exchanged at such office or agency. Whenever any Environmental Control Bonds are so surrendered for exchange, an Authorized Officer shall execute, and the Indenture Trustee shall authenticate and the Environmental Control Bondholder shall obtain from the Indenture Trustee, the Environmental Control Bonds which the Environmental Control Bondholder making the exchange is entitled to receive.

All Environmental Control Bonds issued upon any registration of transfer or exchange of Environmental Control Bonds shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Environmental Control Bonds surrendered upon such registration of transfer or exchange.

Every Environmental Control Bond presented or surrendered for registration of transfer or exchange shall be duly endorsed by, or be accompanied by a written instrument of transfer in the form set forth in Exhibit A to the applicable Series Supplement or such other form as is satisfactory to the Indenture Trustee duly executed by, the Holder thereof or such ▇▇▇▇▇▇’s attorney duly authorized in writing, with such signature guaranteed by an Eligible Guarantor Institution in the form set forth in such Environmental Control Bond.

No service charge shall be made to a Holder for any registration of transfer or exchange of Environmental Control Bonds, but, other than in respect of exchanges pursuant to Sections 2.04 or 2.06 not involving any transfer, the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Environmental Control Bonds.

The preceding provisions of this Section notwithstanding, the Issuer shall not be required to make, and the Bond Registrar need not register, transfers or exchanges of Environmental Control Bonds selected for transfers or exchanges of any Environmental Control Bond for a period of 15 days preceding the date on which final payment of principal is to be made with respect to such Environmental Control Bond.

SECTION 2.06. Mutilated, Destroyed, Lost or Stolen Environmental Control Bonds. If (i) any mutilated Environmental Control Bond is surrendered to the Indenture Trustee, or the Indenture Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Environmental Control Bond, and (ii) there is delivered to the Indenture Trustee such security or indemnity as may be required by it to hold the Issuer and the Indenture Trustee harmless, then, in the absence of notice to the Issuer, the Bond Registrar or the Indenture Trustee that such Environmental Control Bond has been acquired by a bona fide purchaser, an Authorized Officer shall execute, and upon such Authorized Officer’s request the Indenture Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Environmental Control Bond, a replacement Environmental Control Bond of like Series (and, if applicable, Tranche), tenor and initial principal amount in Authorized Initial Denominations, bearing a number not contemporaneously Outstanding; provided, however, that if any such destroyed, lost or stolen Environmental Control Bond, but not a mutilated Environmental Control Bond, shall have become or within seven days shall be due and payable, instead of issuing a replacement Environmental Control Bond, the Issuer may pay such destroyed, lost or stolen Environmental Control Bond when so due or payable without surrender thereof. If, after the delivery of such replacement Environmental Control Bond or payment of a destroyed, lost or stolen Environmental Control Bond pursuant to the proviso to the preceding sentence, a bona fide purchaser of the original Environmental Control Bond in lieu of which such replacement Environmental Control Bond was issued presents for payment such original Environmental Control Bond, the Issuer and the Indenture Trustee shall be entitled to recover such replacement Environmental Control Bond (or such payment) from the Person to whom it was delivered or any Person taking such replacement Environmental Control Bond from such Person to whom such replacement Environmental Control Bond was delivered or any assignee of such Person, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Issuer or the Indenture Trustee in connection therewith.

Upon the issuance of any replacement Environmental Control Bond under this Section, the Issuer may require the payment by the Holder of such Environmental Control Bond of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Indenture Trustee) connected therewith.

Every replacement Environmental Control Bond issued pursuant to this Section in replacement of any mutilated, destroyed, lost or stolen Environmental Control Bond shall constitute an original additional contractual obligation of the Issuer, whether or not the mutilated, destroyed, lost or stolen Environmental Control Bond shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Environmental Control Bonds duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Environmental Control Bonds.

SECTION 2.07. Persons Deemed Owner. Prior to due presentment for registration of transfer of any Environmental Control Bond, the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture Trustee may treat the Person in whose name any Environmental Control Bond is registered (as of the day of determination) as the owner of such Environmental Control Bond for the purpose of receiving payments of principal of and premium, if any, and interest on such Environmental Control Bond and for all other purposes whatsoever, whether or not such Environmental Control Bond be overdue, and neither the Issuer, the Indenture Trustee nor any agent of the Issuer or the Indenture Trustee shall be affected by notice to the contrary. Upon the issuance of Definitive Environmental Control Bonds, the Indenture Trustee shall recognize the Holders of Definitive Environmental Control Bonds as Environmental Control Bondholders.

SECTION 2.08. Payment of Principal, Premium, if any, and Interest; Interest on Overdue Principal and Premium, if any; Principal, Premium and Interest Rights Preserved. (a) The Environmental Control Bonds shall accrue interest as provided in the form of Environmental Control Bond attached to the Series Supplement for such Environmental Control Bonds, at the applicable Bond Rate specified therein, and such interest shall be payable on each Payment Date as specified therein. Any installment of interest, principal or premium, if any, payable on any Environmental Control Bond which is punctually paid or duly provided for by the Issuer on the applicable Payment Date or paid in accordance with the provisions of clause (c) below shall be paid to the Person in whose name such Environmental Control Bond (or one or more Predecessor Environmental Control Bonds) is registered on the Bond Register as of the close of business on the applicable Record Date or Special Record Date, in accordance with clause (c) below, for such Payment Date or Special Record Date, by check mailed first-class, postage prepaid to such Person’s address as it appears on the Bond Register as of the close of business on such date or in such other manner as may be provided in the related Series Supplement, except that (i) upon application to the Indenture Trustee by any Holder owning Environmental Control Bonds of any tranche in the principal amount of $10,000,000 or more not later than the applicable Record Date payment will be made by wire transfer to an account maintained by such Holder in New York, New York; (ii) with respect to Environmental Control Bonds registered as of the close of business on the applicable Record Date or Special Record Date in the name of the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.), payments will be made by wire transfer in immediately available funds to the account designated by such nominee; and (iii) with respect to the final installment of principal and premium, if any, payable with respect to such Environmental Control Bond on a Payment Date, such amounts shall be payable as provided in clause (b) below. The funds represented by any such checks returned undelivered shall be held in accordance with Section 3.03 hereof.

(b) The principal of each Environmental Control Bond of each Series (and, if applicable, Tranche) shall be payable in installments on each Payment Date specified in the Expected Sinking Fund Schedule attached to the Series Supplement for such Environmental Control Bonds, but only to the extent that moneys are available for such payment pursuant to Section 8.02. Failure to pay in accordance with such Expected Sinking Fund Schedule because

moneys are not so available pursuant to Section 8.02 to make such payments shall not constitute a Default or Event of Default under this Indenture. Notwithstanding the foregoing, the entire unpaid principal amount of the Environmental Control Bonds of any Series or Tranche shall be due and payable, if not previously paid (i) on the Series Termination Date (or, if applicable, Tranche Termination Date) therefor or (ii) on the date on which the Environmental Control Bonds of all Series have been declared immediately due and payable in accordance with Section 5.02. The Indenture Trustee shall notify the Person in whose name an Environmental Control Bond is registered at the close of business on the Record Date second preceding the Payment Date on which the Issuer expects that the final installment of principal of and premium, if any, and interest on such Environmental Control Bond will be paid. Such notice shall be mailed no later than ten days prior to such final Payment Date and shall specify that such final installment of principal and premium, if any, will be payable to the Person in whose name an Environmental Control Bond is registered at the close of business on the Record Date immediately preceding such final Payment Date and only upon presentation and surrender of such Environmental Control Bond and shall specify the office or agency of the Indenture Trustee where such Environmental Control Bond may be presented and surrendered for payment of such installment.

(c) If the Issuer defaults in a payment of interest on the Environmental Control Bonds of any Series, or is in default with respect to any amount payable to any Swap Counterparty in accordance with any Swap Agreement, the Issuer shall pay defaulted interest or such other amount, as the case may be, (plus interest on such defaulted interest or on such other amount at the applicable Bond Rate to the extent lawful) in any lawful manner (subject to the availability of such amounts in the related Tranche Subaccount, in the case of interest owed with respect to any Floating Rate Bonds). The Issuer shall pay such defaulted interest to the Persons who are Environmental Control Bondholders and to any Swap Counterparty, as applicable, at the rate specified in the related Series Supplement or Swap Agreement, respectively, on a subsequent Special Record Date, which date shall be at least five Business Days prior to the Special Payment Date. The Issuer shall fix or cause to be fixed any such Special Record Date and Special Payment Date, and, at least fifteen days before any such special record date, the Indenture Trustee shall mail to each affected Environmental Control Bondholder a notice that states the Special Record Date, the Special Payment Date and the amount of defaulted interest (plus interest on the defaulted interest) to be paid.

SECTION 2.09. Cancellation. All Environmental Control Bonds surrendered for payment, registration of transfer or exchange shall, if surrendered to any Person other than the Indenture Trustee, be delivered to the Indenture Trustee and shall be promptly canceled by the Indenture Trustee. The Issuer may at any time deliver to the Indenture Trustee for cancellation any Environmental Control Bonds previously authenticated and delivered hereunder which the Issuer may have acquired in any manner whatsoever, and all Environmental Control Bonds so delivered shall be promptly canceled by the Indenture Trustee. No Environmental Control Bonds shall be authenticated in lieu of or in exchange for any Environmental Control Bonds canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Environmental Control Bonds may be held or disposed of by the Indenture Trustee in accordance with its standard retention or disposal policy as in effect at the time unless the Issuer shall direct by an Issuer Order that they be destroyed or returned to it;

provided that such Issuer Order is timely and the Environmental Control Bonds have not been previously disposed of by the Indenture Trustee.

Such Environmental Control Bond shall initially be registered on the Bond Register in the name of Cede & Co., the nominee of the initial Clearing Agency, and no Bondholder will receive a definitive Environmental Control Bond representing such Holder’s interest in such Environmental Control Bond, except as provided in Section 2.13. Unless and until Definitive Environmental Control Bonds have been issued to Environmental Control Bondholders pursuant to Section 2.13:

(a) the provisions of this Section 2.11 shall be in full force and effect;

(b) the Bond Registrar and the Indenture Trustee shall be entitled to deal with the then acting Clearing Agency for all purposes of this Indenture (including the payment of Principal of and interest on the Environmental Control Bonds and the giving of instructions or directions hereunder) as the sole Holder of the Environmental Control Bonds, and shall have no obligation to the Environmental Control Bond Owners;

(c) to the extent that the provisions of this Section 2.11 conflict with any other provisions of this Indenture, the provisions of this Section 2.11 shall control;

(d) the rights of the Environmental Control Bond Owners shall be exercised only through the then acting Clearing Agency and shall be limited to those established by law and agreements between such the Environmental Control Bond Owners and the Clearing Agency or the Clearing Agency Participants. Pursuant to the DTC Agreement, unless and until Definitive Environmental Control Bonds are issued pursuant to Section 2.13, the initial Clearing Agency will make book-entry transfers among the Clearing Agency Participants and receive and transmit payments of Principal of and interest on the Environmental Control Bonds to such Clearing Agency Participants; and

(e) whenever this Indenture requires or permits actions to be taken based upon instructions or directions of Holders evidencing a specified percentage of the Outstanding Amount of the Environmental Control Bonds or a Series or Tranche thereof, the Clearing Agency shall be deemed to represent such percentage only to the extent that it has received instructions to such effect from the Environmental Control Bond Owners or Clearing Agency Participants owning or representing, respectively, such required percentage of the beneficial interest in the Environmental Control Bonds or such Series or Tranche and has delivered such instructions to the Indenture Trustee.

If (i) the Issuer advises the Indenture Trustee in writing that the then acting Clearing Agency is no longer willing or able to properly discharge its responsibilities as nominee and depository with respect to the book-entry bonds of any Series or Tranche and the Issuer is unable to locate a qualified successor, or (ii) after the occurrence of an Event of Default, Environmental Control Bond Owners representing beneficial interests aggregating no less than a majority of the Outstanding Amount of the Environmental Control Bonds of all Series maintained as book-entry bonds advise the Issuer, the Indenture Trustee and the Clearing Agency in writing that the continuation of a book-entry system through the Clearing Agency is no longer in the best interests of the Environmental Control Bond Owners, then the Clearing Agency shall notify all affected Environmental Control Bond Owners and the Indenture Trustee of the occurrence of any such event and of the availability of Definitive Environmental Control Bonds to affected Environmental Control Bond

None of the Issuer, the Bond Registrar or the Indenture 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 the issuance of Definitive Environmental Control Bonds in accordance with this Section 2.13, the Indenture Trustee shall recognize the Holders of the Definitive Environmental Control Bonds as Environmental Control Bondholders.

Definitive Environmental Control Bonds will be transferable and exchangeable at the offices of the Bond Registrar.

SECTION 2.14. Tax Treatment. The Issuer, by entering into this Indenture, and the Holders and any Persons holding a beneficial interest in any Bond, by acquiring any Bond or interest therein, (i) express their intention that, solely for the purposes of federal income taxes and, to the extent consistent with applicable state, local and other tax law, solely for the purposes of state, local and other taxes, the Bonds qualify under applicable tax law as indebtedness of the Member secured by the Collateral and (ii) solely for the purposes of federal income taxes and, to the extent consistent with applicable state, local and other tax law, solely for purposes of state, local and other taxes, so long as any of the Bonds are outstanding, agree to treat the Bonds as indebtedness of the Member secured by the Collateral unless otherwise required by appropriate taxing authorities.

SECTION 2.15. State Pledge. Under the laws of the State of West Virginia in effect on the Closing Date, the State of West Virginia (including the PSCWV) has pledged and agreed with the Holders, pursuant to Section (q) of the Statute, as follows:

“that the state will not take or permit any action that impairs the value of environmental control property or, except as allowed under subsection (e) of this section reduce, alter or impair environmental control charges that are imposed, collected and remitted for the benefit of the bondholders, any assignee, and any financing parties, until any principal, interest and redemption premium in respect of environmental control bonds, all financing costs and all amounts to be paid to an assignee or financing party under ancillary agreement are paid or performed in full.”

The Issuer hereby acknowledges that the purchase of any Bond by a Holder is made in reliance on such agreement and pledge by the State of West Virginia.

SECTION 2.16. Security Interests. The Issuer hereby makes the following representations and warranties. Other than (i) the security interest granted to the Indenture Trustee pursuant to this Indenture in the applicable Series Supplement and (ii) any security interest granted by the Issuer pursuant to an Additional Issuance, the Issuer has not pledged, granted, sold, conveyed or otherwise assigned any interests or security interests in any Collateral and no security agreement, financing statement or equivalent security or Lien instrument listing the Issuer as debtor covering all or any part of any Collateral is on file or of record in any jurisdiction, except such as may have been filed, recorded or made by the Issuer in favor of the

Indenture Trustee on behalf of the Holders of Bonds secured by such Collateral in connection with this Indenture. This Indenture constitutes a valid and continuing lien on the Collateral in favor of the Indenture Trustee on behalf of the Holders of the Bonds secured by such Collateral, which lien is prior to all other Liens and is enforceable as such as against creditors of and purchasers from the Issuer in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws affecting creditors’ rights generally or by general equitable principles, whether considered in a proceeding at law or in equity and by an implied covenant of good faith and fair dealing. With respect to all Series Collateral, this Indenture together with the related Series Supplement creates a valid and continuing security interest (as defined in the UCC) in the related Series Collateral, which security interest is prior to all other Liens and is enforceable as such as against creditors of and purchasers from the Issuer in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws affecting creditors’ rights generally or by general equitable principles, whether considered in a proceeding at law or in equity and by an implied covenant of good faith and fair dealing. The Issuer has good and marketable title to the Collateral free and clear of any Lien, claim or encumbrance of any Person. All of the Collateral constitute either Environmental Control Property, deposit accounts, investment property or general intangibles (as each such term is defined in the UCC) except that proceeds of the Collateral may also take the form of instruments. The Issuer has taken, or caused the Servicer to take, all action necessary to perfect the security interest in the Series Collateral granted to the Indenture Trustee pursuant to this Indenture in the applicable Series Supplement. The Issuer has filed (or has caused the Servicer to file) all appropriate financing statements in the proper filing offices in the appropriate jurisdictions under applicable law in order to perfect the security interest in the Series Collateral granted to the Indenture Trustee for the benefit of the Secured Parties of each related Series. The Issuer has not authorized the filing of and is not aware of any financing statements against the Issuer that include a description of the Collateral other than those filed in favor of the Indenture Trustee. The Issuer is not aware of any judgment or tax Lien filings against the Issuer. The Collection Account (including all subaccounts thereof) constitutes a “securities account” within the meaning of the UCC. The Issuer has taken all steps necessary to cause the securities intermediary of each such securities account to identify in its records the Indenture Trustee as the person having a Security Entitlement against the securities intermediary in such securities account, the Collection Account for such Series of Bonds is not in the name of any Person other than the Indenture Trustee, and the Issuer has not consented to the securities intermediary of the Collection Account for such Series of Bonds to comply with entitlement orders of any Person other than the Indenture Trustee. All of the Series Collateral constituting investment property has been and will have been credited to the Collection Account for such Series of Bonds or a subaccount thereof, and the entity acting as Indenture Trustee, in its capacity as the securities intermediary for such Collection Account, has agreed to treat all assets credited to the Collection Account for such Series of Bonds as “financial assets” within the meaning of the UCC. Accordingly, the Indenture Trustee has a first priority perfected security interest in the Collection Account for such Series of Bonds, all funds and financial assets on deposit therein, and all Securities Entitlements relating thereto. The representations and warranties set forth in this Section 2.16 shall survive the execution and delivery of this Indenture and the issuance of any Bonds, shall be deemed re-made on each date on which any funds in the Collection Account for each Series of Bonds are distributed to Issuer or otherwise released from the lien of the Indenture

and may not be waived by any party hereto except pursuant to a supplemental indenture executed in accordance with Article IX and as to which the Rating Agency Condition has been satisfied.

(iii) at any time during the continuance of any such Default or Event of Default, upon the written request of the Indenture Trustee, forthwith pay to the Indenture Trustee all sums so held in trust by such Paying Agent;

Subject to applicable laws with respect to escheat of funds, any money held by the Indenture Trustee or any Paying Agent in trust for the payment of any amount of principal of, premium on, if any, or interest on any Environmental Control Bond and remaining unclaimed for two years after such amount has become due and payable shall be discharged from such trust and be paid to the Issuer on Issuer Request; and the Holder of such Environmental Control Bond shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof (but only to the extent of the amounts so paid to the Issuer), and all liability of the Indenture Trustee or such Paying Agent with respect to such trust money shall thereupon cease; provided, however, that the Indenture Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in the City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Issuer.

(h) If a Servicer Default shall arise from the failure of the Servicer to perform any of its duties or obligations under the Servicing Agreement with respect to the Transferred Environmental Control Property or the Environmental Control Charges, the Issuer shall take all reasonable steps available to it to remedy such failure. The Issuer shall not take any action to terminate the Servicer’s rights and powers under the Servicing Agreement following a Servicer Default without the prior written consent of (i) the PSCWV, (ii) Indenture Trustee or of the Holders of Environmental Control Bonds evidencing not less than 25% of the Outstanding Amount of the Environmental Control Bonds of all Series and (iii) the prior written consent, not to be unreasonably withheld, of any Counterparties affected thereby.

In connection with any such appointment, the Issuer may make such arrangements for the compensation of such Successor Servicer as it and such Successor Servicer shall agree, subject to the limitations set forth below and in the Servicing Agreement, and in accordance with Section 6.04 of the Servicing Agreement, the Issuer shall enter into an agreement with such Successor Servicer for the servicing of the Transferred Environmental Control Property (such agreement to be in form and substance satisfactory to the Indenture Trustee).

Bondholders and the Rating Agencies of such appointment, specifying in such notice the name and address of such Successor Servicer.

(k) The Issuer shall not take any action to terminate or assign a Swap Counterparty’s rights and powers under any Swap Agreement or replace a Swap Counterparty following an event of default, termination event or downgrade event under a Swap Agreement without (i) the prior written consent of the Indenture Trustee and of the Holders of that percentage of the Outstanding Amount of the Environmental Control Bonds, if any such consent is required under the related Series Supplement, of the related Series and Tranche, if any, as specified in the related Series Supplement, and (ii) satisfying any other requirements set forth in the related Series Supplement and Swap Agreement.

SECTION 3.22. Separate Entity. The Issuer shall take all reasonable steps to continue its identity as a separate legal entity and to make it apparent to third parties that it is an entity with assets and liabilities distinct from those of the Transferor and the Seller, other affiliates or any other Person.

If the Issuer exercises the Covenant Defeasance Option with respect to any Series, the maturity of the Environmental Control Bonds of such Series may not be accelerated because of an Event of Default specified in Section 5.01(iv).

Upon satisfaction of the conditions set forth herein to the exercise of the Legal Defeasance Option or the Covenant Defeasance Option with respect to any Series of Environmental Control Bonds, the Indenture Trustee, on reasonable written demand of and at the expense of the Issuer, shall execute proper instruments acknowledging satisfaction and discharge of the obligations that are terminated pursuant to such exercise.

Thereafter, the obligations in Sections 6.07 and 4.04 with respect to such Series shall survive.

SECTION 4.02. Conditions to Defeasance. The Issuer may exercise the Legal Defeasance Option or the Covenant Defeasance Option with respect to any Series of Environmental Control Bonds only if:

(a) the Issuer irrevocably deposits or causes to be deposited in trust with the Indenture Trustee cash or U.S. Government Obligations maturing as to principal and interest in such amounts and at such times will insure the availability of cash (or a combination thereof) for the payment of principal of and premium, if any, and interest on such Environmental Control Bonds to the Expected Payment Date, such deposit to be made in the Defeasance Subaccount for such Series of Environmental Control Bonds;

(b) the Issuer delivers to the Indenture Trustee a certificate from a nationally recognized firm of independent registered public accountants expressing its opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited cash without investment will provide cash at such times and in such amounts (but, in the case of the Legal Defeasance Option only, not more than such amounts) as will be sufficient to pay in respect of the Environmental Control Bonds of such Series (i) principal in accordance with the Expected Sinking Fund Schedule therefor and (ii) interest when due;

(c) in the case of the Legal Defeasance Option, ninety-five days pass after the deposit is made and during the ninety-five-day period no Default specified in Section 5.01(iv) or (v) occurs which is continuing at the end of the period;

(d) no Default or Event of Default has occurred and is continuing on the day of such deposit and after giving effect thereto;

(e) in the case of the Legal Defeasance Option, the Issuer delivers to the Indenture Trustee an Opinion of Counsel from external counsel stating that (i) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of execution of this Indenture, there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the Environmental Control Bonds of such Series will not recognize income, gain or loss for Federal income tax purposes as a result of the exercise of such Legal Defeasance Option and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(f) in the case of the Covenant Defeasance Option, the Issuer delivers to the Indenture Trustee an Opinion of Counsel to the effect that the Holders of the Environmental Control Bonds of such Series will not recognize income, gain or loss for Federal income tax purposes as a result of the exercise of such Covenant Defeasance Option and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

SECTION 4.03. Application of Trust Money. All moneys or U.S. Government Obligations deposited with the Indenture Trustee pursuant to Section 4.01 or 4.02 hereof with respect to any Series of Environmental Control Bonds shall be held in trust in the Defeasance Subaccount for such Series and applied by it, in accordance with the provisions of the Environmental Control Bonds and this Indenture, to the payment, either directly or through any Paying Agent, as the Indenture Trustee may determine, to the Holders of the particular Environmental Control Bonds for the payment or redemption of which such moneys have been deposited with the Indenture Trustee, of all sums due and to become due thereon for principal, premium, if any, and interest. Such moneys shall be segregated and held apart solely for paying such Environmental Control Bonds and such Environmental Control Bonds shall not be entitled to any amounts on deposit in the Collection Account other than amounts on deposit in the Defeasance Subaccount for such Environmental Control Bonds.

SECTION 4.04. Repayment of Moneys Held by Paying Agent. In connection with the satisfaction and discharge of this Indenture or the exercise of the Covenant Defeasance Option or the Legal Defeasance Option with respect to the Environmental Control Bonds of any Series, all moneys then held by any Paying Agent other than the Indenture Trustee under the provisions of this Indenture with respect to such Environmental Control Bonds shall, upon demand of the Issuer, be paid to the Indenture Trustee to be held and applied according to Section 3.03 and thereupon such Paying Agent shall be released from all further liability with respect to such moneys.

ARTICLE V

Remedies

SECTION 5.01. Events of Default. “Event of Default” with respect to any Series, wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(i) default in the payment of any interest on any Environmental Control Bond when the same becomes due and payable, and such default shall continue for a period of five Business Days;

(ii) default in the payment of the then unpaid principal of any Environmental Control Bond of any Series on the Series Termination Date for such Series or, if applicable, any Tranche on the Tranche Termination Date for such Tranche;

(iii) default in the observance or performance of any covenant or agreement of the Issuer made in this Indenture (other than a covenant or agreement, a default in the observance or performance of which is specifically dealt with in clause (i) or (ii) above), or any material representation or warranty of the Issuer made in this Indenture or in any certificate or writing delivered pursuant hereto or in connection herewith proves to have been incorrect in any material respect as of the time when made, and such default shall continue or not be cured, or such representation or warranty shall continue to be incorrect or not cured, as applicable, for a period of thirty days after the earlier of (A) the date there shall have been given, by registered or certified mail, to the Issuer by the Indenture Trustee or to the Issuer and the Indenture Trustee by the Holders of at least 25% of the Outstanding Amount of the Environmental Control Bonds of any Series, a written notice specifying such default or incorrect representation or warranty and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or (B) the date that the Issuer has actual knowledge of the default;

(iv) the filing of a decree or order for relief by a court having jurisdiction in the premises in respect of the Issuer or any substantial part of the Collateral in an involuntary case under any applicable Federal or state bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of the Issuer or for any substantial part of the Collateral, or ordering the winding-up or liquidation of the Issuer’s affairs, and such decree or order shall remain unstayed and in effect for a period of ninety consecutive days;

(v) the commencement by the Issuer of a voluntary case under any applicable Federal or state bankruptcy, insolvency or other similar law now or hereafter in effect, or the consent by the Issuer to the entry of an order for relief in an involuntary case under any such law, or the consent by the Issuer to the appointment or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar

official of the Issuer or for any substantial part of the Collateral, or the making by the Issuer of any general assignment for the benefit of creditors, or the failure by the Issuer generally to pay its debts as such debts become due, or the taking of action by the Issuer in furtherance of any of the foregoing; or

(vi) any act or failure to act by the State of West Virginia or any of its agencies (including the PSCWV), officers or employees that violates or is not in accordance with the pledge and agreement of the State of West Virginia in Section (q) of the Statute (▇.▇▇ Code, § 24-2-4e(q)).

The Issuer shall deliver to a Responsible Officer of the Indenture Trustee, the PSCWV and the Rating Agencies, within five days after an Authorized Officer has knowledge of the occurrence thereof, written notice in the form of an Officer’s Certificate of any event which with the giving of notice and the lapse of time would become an Event of Default under clause (iii) above, its status and what action the Issuer is taking or proposes to take with respect thereto. An Event of Default with respect to one Series of Environmental Control Bonds will not automatically trigger an Event of Default with respect to any other Outstanding Series of Environmental Control Bonds.

SECTION 5.02. Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default under Section 5.01(vi)) occurs and is continuing with respect to any Series, then and in every such case either the Indenture Trustee or the Holders of Environmental Control Bonds representing not less than a majority of the Outstanding Amount of the Environmental Control Bonds of such Series may, but need not, declare the Environmental Control Bonds of such Series to be immediately due and payable, by a notice in writing to the Issuer (and to the Indenture Trustee and the PSCWV if given by Environmental Control Bondholders), and upon any such declaration the unpaid principal amount of the Environmental Control Bonds of such Series, together with accrued and unpaid interest thereon through the date of acceleration, shall become immediately due and payable.

At any time after such declaration of acceleration of maturity has been made and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee as hereinafter in this Article V provided, the Holders of Environmental Control Bonds representing a majority of the Outstanding Amount of the Environmental Control Bonds of such Series, by written notice to the Issuer, the PSCWV and the Indenture Trustee, may rescind and annul such declaration and its consequences if:

(i) the Issuer has paid or deposited with the Indenture Trustee, for deposit in the General Subaccount of the Collection Account, a sum sufficient to pay

(A) all payments of principal of and premium, if any, and interest on all Environmental Control Bonds of all Series due and owing and all other amounts that would then be due hereunder or upon such Environmental Control Bonds if the Event of Default giving rise to such acceleration had not occurred; and

(B) all sums paid or advanced by the Indenture Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its agents and counsel; and

(ii) all Events of Default with respect to such Series, other than the nonpayment of the principal of the Environmental Control Bonds of such Series during that has become due solely by such acceleration, have been cured or waived as provided in Section 5.12.

No such rescission shall affect any subsequent Event of Default or impair any right consequent thereto.

SECTION 5.03. Collection of Indebtedness and Suits for Enforcement by Indenture Trustee. (a) The Issuer covenants that if (i) default is made in the payment of any interest on any Environmental Control Bond when such interest becomes due and payable and such Default continues for a period of five Business Days, or (ii) default is made in the payment of the then unpaid principal of any Environmental Control Bond on the Series Termination Date or Tranche Termination Date, as applicable, therefor, the Issuer will, upon demand of the Indenture Trustee, pay to it, for the benefit of the Holders of the Environmental Control Bonds of such Series, such amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its agents and counsel and the whole amount then due and payable on such Environmental Control Bonds for principal, premium, if any, and interest, with interest upon the overdue principal and premium, if any, and, to the extent payment at such rate of interest shall be legally enforceable, upon overdue installments of interest, at the respective Bond Rate of such Series or the applicable Tranche of such Series and in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its agents and counsel.

(b) In case the Issuer shall fail forthwith to pay the amounts specified in clause (a) above upon such demand, the Indenture Trustee, in its own name and as trustee of an express trust, may institute a Proceeding for the collection of the sums so due and unpaid, and may prosecute such Proceeding to judgment or final decree, and may enforce the same against the Issuer or other obligor upon such Environmental Control Bonds and collect in the manner provided by law out of the property of the Issuer or other obligor upon such Environmental Control Bonds, wherever situated, the moneys adjudged or decreed to be payable.

(c) If an Event of Default occurs and is continuing, the Indenture Trustee may, as more particularly provided in Section 5.04, in its discretion, proceed to protect and enforce its rights and the rights of the Environmental Control Bondholders, by such appropriate Proceedings as the Indenture Trustee shall deem most effective to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy or legal or equitable right vested in the Indenture Trustee by this Indenture or by law including foreclosing or otherwise enforcing the lien on the Transferred Environmental Control Property securing the Environmental Control Bonds or applying to the PSCWV or to a court of competent jurisdiction

in accordance with the Statute for sequestration of revenues arising with respect to such Transferred Environmental Control Property.

(d) In case there shall be pending, relative to the Issuer or any other obligor upon the Environmental Control Bonds or any Person having or claiming an ownership interest in the Collateral, Proceedings under Title 11 of the United States Code or any other applicable Federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Issuer or its property or such other obligor or Person, or in case of any other comparable judicial Proceedings relative to the Issuer or other obligor upon the Environmental Control Bonds, or to the creditors or property of the Issuer or such other obligor, the Indenture Trustee, irrespective of whether the principal of any Environmental Control Bonds shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Indenture Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such Proceedings or otherwise:

(i) to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest owing and unpaid in respect of the Environmental Control Bonds and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Indenture Trustee (including any claim for reasonable compensation to the Indenture Trustee and each predecessor Indenture Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Indenture Trustee and each predecessor Indenture Trustee, except as a result of negligence or bad faith), the Environmental Control Bondholders;

(ii) unless prohibited by applicable law and regulations, to vote on behalf of the Holders of Environmental Control Bonds in any election of a trustee, a standby trustee or Person performing similar functions in any such Proceedings;

(iii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute all amounts received with respect to the claims of the Environmental Control Bondholders and of the Indenture Trustee on their behalf; and

(iv) to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Indenture Trustee or the Holders of Environmental Control Bonds allowed in any judicial proceedings relative to the Issuer, its creditors and its property;

and any trustee, receiver, liquidator, custodian or other similar official in any such Proceeding is hereby authorized by each of such Environmental Control Bondholders to make payments to the Indenture Trustee, and, in the event that the Indenture Trustee shall consent to the making of payments directly to such Environmental Control Bondholders, to pay to the Indenture Trustee such amounts as shall be sufficient to cover reasonable compensation to the Indenture Trustee, each predecessor Indenture Trustee and their respective agents, attorneys and counsel, and all

other expenses and liabilities incurred, and all advances made, by the Indenture Trustee and each predecessor Indenture Trustee except as a result of negligence or bad faith.

(e) Nothing herein contained shall be deemed to authorize the Indenture Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Environmental Control Bondholder any plan of reorganization, arrangement, adjustment or composition affecting the Environmental Control Bonds or the rights of any Holder thereof or to authorize the Indenture Trustee to vote in respect of the claim of any Environmental Control Bondholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar Person.

(f) All rights of action and of asserting claims under this Indenture, or under any of the Environmental Control Bonds of any Series, may be enforced by the Indenture Trustee without the possession of any of the Environmental Control Bonds of such Series or the production thereof in any trial or other Proceedings relative thereto, and any such action or Proceedings instituted by the Indenture Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Indenture Trustee, each predecessor Indenture Trustee and their respective agents and attorneys, shall be for the ratable benefit of the Holders of the Environmental Control Bonds of such Series.

(g) In any Proceedings brought by the Indenture Trustee (and also any Proceedings involving the interpretation of any provision of this Indenture to which the Indenture Trustee shall be a party), the Indenture Trustee shall be held to represent all the Holders of the Environmental Control Bonds, and it shall not be necessary to make any Environmental Control Bondholder a party to any such Proceedings.

SECTION 5.04. Remedies; Priorities. (a) If an Event of Default (other than an Event of Default under Section 5.01(vi)) occurs and is continuing with respect to a Series, the Indenture Trustee may do one or more of the following (subject to Section 5.05):

(i) institute Proceedings in its own name and as trustee of an express trust for the collection of all amounts then payable on the Environmental Control Bonds of such Series or under this Indenture with respect thereto, whether by declaration or otherwise, enforce any judgment obtained, and collect from the Issuer and any other obligor upon such Environmental Control Bonds moneys adjudged due;

(ii) institute Proceedings from time to time for the complete or partial foreclosure of this Indenture with respect to the Series Collateral;

(iii) exercise any remedies of a secured party under the West Virginia UCC, the Delaware UCC or the Statute or any other applicable law and take any other appropriate action to protect and enforce the rights and remedies of the Indenture Trustee and the Holders of the Environmental Control Bonds of such Series;

(iv) sell the Series Collateral or any portion thereof or rights or interest therein, at one or more public or private sales called and conducted in any manner permitted by law; and

(v) exercise all rights, remedies, powers, privileges and claims of the Issuer against the Transferor, the Seller, the Servicer or any Swap Counterparty under or in connection with the Transfer Agreement, the Sale Agreement, the Servicing Agreement or the related Swap Agreement as provided in Section 3.20(b);

provided, however, that the Indenture Trustee may not sell or otherwise liquidate any portion of the Collateral following an Event of Default, other than an Event of Default described in Section 5.01(i) or (ii), with respect to any Series unless (A) the Holders of 100% of the Outstanding Amount of the Environmental Control Bonds of all Series consent in writing thereto, (B) the proceeds of such sale or liquidation distributable to the Environmental Control Bondholders of all Series are sufficient to discharge in full all amounts then due and unpaid upon such Environmental Control Bonds for principal, premium, if any, and interest or (C) the Indenture Trustee determines, after having been advised in writing by the Servicer, that the Collateral will not continue to provide sufficient funds for all payments on the Environmental Control Bonds of all Series as they would have become due if the Environmental Control Bonds had not been declared due and payable, and the Indenture Trustee obtains the consent of Holders of 66²/₃% of the Outstanding Amount of the Environmental Control Bonds of all Series. In determining such sufficiency or insufficiency with respect to clause (B) and (C), the Indenture Trustee may, but need not, obtain and conclusively rely upon an opinion of an Independent investment banking or accounting firm of national reputation as to the feasibility of such proposed action and as to the sufficiency of the Collateral for such purpose.

(b) If an Event of Default under Section 5.01(vi) occurs and is continuing, the Indenture Trustee, for the benefit of the Holders of the related Series, shall be entitled and empowered to the extent permitted by applicable law to institute or participate in Proceedings reasonably necessary to compel performance of or to enforce the pledge and agreement of the State of West Virginia in Section (q) of the Statute (▇.▇▇ Code, § 24-2-4e(q)) and to collect monetary damages incurred by the Holders or the Indenture Trustee as a result of any such Event of Default, and may prosecute any such Proceedings to final judgment or decree. Such remedy shall be the only remedy that the Indenture Trustee may exercise if the only Event of Default that has occurred and is continuing is an Event of Default under Section 5.01(vi).

(c) If the Indenture Trustee collects any money pursuant to this Article V, it shall pay out such money in accordance with the priorities set forth in Section 8.02(e).

SECTION 5.05. Optional Preservation of the Collateral. If the Environmental Control Bonds of any Series have been declared to be due and payable under Section 5.02 following an Event of Default and such declaration and its consequences have not been rescinded and annulled, the Indenture Trustee may, but need not, elect, as provided in Section 5.11(iii), to maintain possession of the related Series Collateral and not sell or liquidate the same. It is the desire of the parties hereto and the Environmental Control Bondholders that there be at all times sufficient funds for the payment of principal of and premium, if any, and interest on the Environmental Control Bonds, and the Indenture Trustee shall take such desire into account when determining whether or not to maintain possession of the Series Collateral or sell or liquidate the same. In determining whether to maintain possession of the Series Collateral or sell or liquidate the same, the Indenture Trustee may, but need not, obtain and rely upon an opinion of an Independent investment banking or registered public accounting firm of national

reputation as to the feasibility of such proposed action and as to the sufficiency of the Series Collateral for such purpose.

SECTION 5.06. Limitation of Proceedings. No Holder of any Environmental Control Bond of any Series shall have any right to institute any Proceeding, judicial or otherwise, or to avail itself of the remedies provided in the Statute, with respect to this Indenture and the related Series Supplement, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(i) such Holder has previously given written notice to the Indenture Trustee of a continuing Event of Default with respect to such Series;

(ii) the Holders of not less than 25% of the Outstanding Amount of the Environmental Control Bonds of each Series have made written request to the Indenture Trustee to institute such Proceeding in respect of such Event of Default in its own name as Indenture Trustee hereunder;

(iii) such Holder or Holders have offered to the Indenture Trustee security or indemnity reasonably satisfactory to the Indenture Trustee against the costs, expenses and liabilities to be incurred in complying with such request;

(iv) the Indenture Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute such Proceedings; and

(v) no direction inconsistent with such written request has been given to the Indenture Trustee during such 60-day period by the Holders of a majority of the Outstanding Amount of the Environmental Control Bonds of all Series;

it being understood and intended that no one or more Holders of Environmental Control Bonds shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders of Environmental Control Bonds or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided.

In the event the Indenture Trustee shall receive conflicting or inconsistent requests and indemnity from two or more groups of Holders of Environmental Control Bonds, each representing less than a majority of the Outstanding Amount of the Environmental Control Bonds of all Series, the Indenture Trustee in its sole discretion may determine what action, if any, shall be taken, notwithstanding any other provisions of this Indenture.

SECTION 5.07. Unconditional Rights of Environmental Control Bondholders To Receive Principal, Premium, if any, and Interest. Notwithstanding any other provisions in this Indenture, the Holder of any Environmental Control Bond shall have the right, which is absolute and unconditional, (a) to receive payment of (i) the interest, if any, on such Environmental Control Bond on or after the due dates thereof expressed in such Environmental Control Bond or in this Indenture or (ii) the unpaid principal, if any, of such Environmental Control Bonds on or after the Series Termination Date or Tranche Termination Date therefor and

(b) to institute suit for the enforcement of any such payment, and such right shall not be impaired without the consent of such Holder.

SECTION 5.08. Restoration of Rights and Remedies. If the Indenture Trustee or any Environmental Control Bondholder has instituted any Proceeding to enforce any right or remedy under this Indenture and such Proceeding has been discontinued or abandoned for any reason or has been determined adversely to the Indenture Trustee or to such Environmental Control Bondholder, then and in every such case the Issuer, the Indenture Trustee and the Environmental Control Bondholders shall, subject to any determination in such Proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Indenture Trustee and the Environmental Control Bondholders shall continue as though no such Proceeding had been instituted.

SECTION 5.09. Rights and Remedies Cumulative. No right or remedy herein conferred upon or reserved to the Indenture Trustee or to the Environmental Control Bondholders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 5.10. Delay or Omission Not a Waiver. No delay or omission of the Indenture Trustee or any Environmental Control Bondholder to exercise any right or remedy accruing upon any Default or Event of Default shall impair any such right or remedy or constitute a waiver of any such Default or Event of Default or an acquiescence therein. Every right and remedy given by this Article V or by law to the Indenture Trustee or to the Environmental Control Bondholders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Environmental Control Bondholders, as the case may be.

SECTION 5.11. Control by Environmental Control Bondholders. The Holders of not less than a majority of the Outstanding Amount of the Environmental Control Bonds of all Series (or, if less than all Series or Tranches are affected, the affected Series or Tranche or Tranches) shall have the right to direct the time, method and place of conducting any Proceeding for any remedy available to the Indenture Trustee with respect to the Environmental Control Bonds of such Series or Tranche or Tranches of exercising any trust or power conferred on the Indenture Trustee with respect to such Series or Tranche or Tranches; provided that

(i) such direction shall not be in conflict with any rule of law or with this Indenture;

(ii) subject to the express terms of Section 5.04, any direction to the Indenture Trustee to sell or liquidate any Series Collateral shall be by the Holders of Environmental Control Bonds representing not less than 100% of the Outstanding Amount of the Environmental Control Bonds of the affected Series;

(iii) if the conditions set forth in Section 5.05 have been satisfied and the Indenture Trustee elects to retain the Series Collateral pursuant to such Section and not sell or liquidate the same, then any direction to the Indenture Trustee by Holders of Environmental Control Bonds representing less than 100% of the Outstanding Amount of the Environmental Control Bonds of all Series to sell or liquidate the Series Collateral shall be of no force and effect; and

(iv) the Indenture Trustee may take any other action deemed proper by the Indenture Trustee that is not inconsistent with such direction;

provided, however, that, subject to Section 6.01, the Indenture Trustee need not take any action that it determines might involve it in liability for which it would not be adequately indemnified to its satisfaction against any cost, expense or liability or if the Indenture Trustee determines that such action might materially and adversely affect the rights of any Holders not consenting to such action.

SECTION 5.12. Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity of the Environmental Control Bonds of all Series as provided in Section 5.02 and upon satisfaction of the PSCWV Condition set forth in 9.03 of this Indenture, the Holders of not less than a majority of the Outstanding Amount of the Environmental Control Bonds of an affected Series may waive any past Default or Event of Default and its consequences except a Default (i) in payment of principal of or premium, if any, or interest on any of the Environmental Control Bonds or (ii) in respect of a covenant or provision hereof that cannot be modified or amended without the consent of the Holders of each Environmental Control Bond of all Series or Tranches affected. In the case of any such waiver, the Issuer, the Indenture Trustee and the Holders of the Environmental Control Bonds shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereto.

Upon any such waiver, such Default shall cease to exist and be deemed to have been cured and not to have occurred, and any Event of Default arising therefrom shall be deemed to have been cured and not to have occurred, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto.

SECTION 5.13. Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Environmental Control Bond by such ▇▇▇▇▇▇’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken, suffered or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to (a) any suit instituted by the Indenture Trustee, (b) any suit instituted by any Environmental Control Bondholder, or group of Environmental Control Bondholders, in each case holding in the aggregate more than 10% of the Outstanding Amount of the Environmental Control Bonds of a

Series or (c) any suit instituted by any Environmental Control Bondholder for the enforcement of the payment of (i) interest on any Environmental Control Bond on or after the due dates expressed in such Environmental Control Bond and in this Indenture or (ii) the unpaid principal, if any, of any Environmental Control Bond on or after the Series Termination Date or Tranche Termination Date, if applicable, therefor.

SECTION 5.14. Waiver of Stay or Extension Laws. The Issuer covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead or in any manner whatsoever, claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 5.15. Action on Environmental Control Bonds. The Indenture Trustee’s right to seek and recover judgment on the Environmental Control Bonds or under this Indenture shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture. Neither the lien of this Indenture nor any rights or remedies of the Indenture Trustee or the Environmental Control Bondholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuer or by the levy of any execution under such judgment upon any portion of the Collateral or upon any of the assets of the Issuer.

SECTION 6.04. Indenture Trustee’s Disclaimer.

Except in the case of a Default in payment of principal of or premium, if any, or interest on any Environmental Control Bond, the Indenture Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Environmental Control Bondholders.

SECTION 6.06. Reports by Indenture Trustee to Holders. (a) So long as the Indenture Trustee is the Bond Registrar, upon the written request of any Owner, within the prescribed period of time for tax reporting purposes after the end of each calendar year during the term of the Bonds, the Indenture Trustee shall deliver to each relevant current or former Owner such information as may be required to enable such Owner to prepare its Federal and state income tax returns.

(b) With respect to each Series of Environmental Control Bonds, on or prior to each Payment Date or Special Payment Date therefor, the Indenture Trustee will make available on its website at ▇▇▇.▇▇▇▇▇▇.▇▇▇/▇▇▇, a statement prepared by the Servicer in accordance with Section 5.12 of the Servicing Agreement to each Holder of Environmental Control Bonds and the PSCWV which will include (to the extent applicable) the following information (and any other information so specified in the Series Supplement for such Series) as to the Environmental Control Bonds of such Series with respect to such Payment Date, or Special Payment Date or the period since the previous Payment Date or Special Payment Date, as applicable:

(i) the amount paid to Holders of such Environmental Control Bonds in respect of principal, such amount to be expressed as a dollar amount per thousand;

(ii) the amount paid to Holders of such Environmental Control Bonds in respect of interest, such amount to be expressed as a dollar amount per thousand;

(iii) the Environmental Control Bond Balance, after giving effect to the payments to be made on such Payment Date, and the Projected Environmental Control Bond Balance, in each case for such Series and as of the most recent Payment Date, and the difference between such amounts;

(iv) the amount, if any, on deposit in the Capital Subaccount and the Required Capital Amount, in each case as of that Payment Date;

(v) the amount, if any, on deposit in the Excess Funds Subaccount as of that Payment Date;

(vi) the amount, if any, to be paid to each Swap Counterparty on that Payment Date to the extent provided in any Swap Agreement;

(c) The Indenture Trustee’s responsibility for disbursing the information described in subsection (b) above to Holders of Environmental Control Bonds and the PSCWV is limited to the availability, timeliness and accuracy of the information provided by the Servicer pursuant to the Servicing Agreement and the Indenture Trustee shall not be responsible for, and shall have no liability with respect to verifying such information.

SECTION 6.07. Compensation and Indemnity. The Issuer shall pay to the Indenture Trustee from time to time compensation for its services. The Indenture Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Indenture Trustee for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Indenture Trustee’s agents, counsel, accountants and experts. The Issuer shall indemnify and hold harmless the Indenture Trustee and its officers, directors, employees and agents, to the extent permitted by law, from and against any and all costs, damages, expenses, losses, taxes (other than taxes imposed on the Indenture Trustee in connection with fees and amounts earned or obtained in accordance with this Indenture), liabilities or other amounts whatsoever (including reasonable counsel fees and expenses) incurred by the Indenture Trustee in connection with the administration of this trust, the enforcement of this trust and all of the Indenture Trustee’s rights, powers and duties under this Indenture and the other Basic Documents to which the Indenture Trustee is a party and the performance by the Indenture Trustee of the duties and obligations of the Indenture Trustee under or pursuant to this Indenture and the other Basic Documents to which the Indenture Trustee is a party. The Indenture Trustee shall notify the Issuer as soon as is reasonably practicable of any claim for which it may seek indemnity. Failure by the Indenture Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Indenture Trustee may have separate counsel and the Issuer shall pay the fees and expenses of such counsel. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Indenture Trustee (i) through the Indenture

Trustee’s own willful misconduct, negligence or bad faith or (ii) to the extent the Indenture Trustee was reimbursed for or indemnified against any such loss, liability or expense by the Transferor pursuant to the Transfer Agreement, the Seller pursuant to the Sale Agreement or by the Servicer pursuant to the Servicing Agreement.

The Issuer’s payment obligations to the Indenture Trustee pursuant to this Section shall survive the discharge of this Indenture or the earlier resignation or removal of the Indenture Trustee. When the Indenture Trustee incurs expenses after the occurrence of a Default or Event of Default specified in Section 5.01(iv) or (v) with respect to the Issuer, the expenses are intended to constitute expenses of administration under Title 11 of the United States Code or any other applicable Federal or state bankruptcy, insolvency or similar law.

SECTION 6.08. Replacement of Indenture Trustee. The Indenture Trustee may resign at any time upon 30 days’ prior written notice by so notifying the Issuer. The Holders of a majority in Outstanding Amount of the Environmental Control Bonds of all Series may remove the Indenture Trustee by so notifying the Issuer and the Indenture Trustee and may appoint a successor Indenture Trustee. The Issuer shall remove the Indenture Trustee if:

(i) the Indenture Trustee fails to comply with Section 6.11;

(ii) the Indenture Trustee is adjudged a bankrupt or insolvent;

(iii) a receiver or other public officer takes charge of the Indenture Trustee or its property;

(iv) the Indenture Trustee otherwise becomes incapable of acting.

(v) the Indenture Trustee fails to provide to the Issuer any information reasonably requested by the Issuer pertaining to the Indenture Trustee and necessary for the Issuer to comply with its reporting obligations under the Exchange Act and Regulation AB and such failure is not resolved to the Issuer’s and the Indenture Trustee’s mutual satisfaction within a reasonable period of time.

If the Indenture Trustee resigns or is removed or if a vacancy exists in the office of Indenture Trustee for any reason (the Indenture Trustee in such event being referred to herein as the “Retiring Indenture Trustee”), the Issuer shall promptly appoint a successor Indenture Trustee.

A successor Indenture Trustee shall deliver a written acceptance of its appointment to the Retiring Indenture Trustee and to the Issuer. Thereupon the resignation or removal of the Retiring Indenture Trustee shall become effective, and the successor Indenture Trustee shall have all the rights, powers and duties of the Indenture Trustee under this Indenture. No resignation or removal of the Indenture Trustee pursuant to this Section 6.08 shall become effective until the acceptance of the appointment by a successor Indenture Trustee. The successor Indenture Trustee shall mail a notice of its succession to Environmental Control Bondholders. The Retiring Indenture Trustee shall promptly transfer all property held by it as Indenture Trustee to the successor Indenture Trustee.

If a successor Indenture Trustee does not take office within 60 days after the Retiring Indenture Trustee resigns or is removed, the Retiring Indenture Trustee, the Issuer or the Holders of a majority in Outstanding Amount of the Environmental Control Bonds of all Series may petition any court of competent jurisdiction for the appointment of a successor Indenture Trustee.

If the Indenture Trustee fails to comply with Section 6.11, any Environmental Control Bondholder may petition any court of competent jurisdiction for the removal of the Indenture Trustee and the appointment of a successor Indenture Trustee.

The Issuer shall promptly furnish written notification of the appointment of any successor Indenture Trustee pursuant to this Section 6.08 to each of the Rating Agencies. The Issuer shall be responsible for payment of the expenses of any resignation or removal of the Indenture Trustee.

Notwithstanding the replacement of the Indenture Trustee pursuant to this Section 6.08, the Issuer’s obligations under Section 6.07 shall continue for the benefit of the Retiring Indenture Trustee.

SECTION 6.09. Successor Indenture Trustee by ▇▇▇▇▇▇. If the Indenture Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association shall, without any further act, be the successor Indenture Trustee. The Issuer shall promptly furnish written notification of any such successor Indenture Trustee to each of the Rating Agencies.

If at the time such successor or successors by merger, conversion consolidation or transfer shall succeed to the trusts created by this Indenture, any of the Environmental Control Bonds shall have been authenticated but not delivered, any such successor to the Indenture Trustee may adopt the certificate of authentication of any Retiring Indenture Trustee, and deliver such Environmental Control Bonds so authenticated; and if at that time any of the Environmental Control Bonds shall not have been authenticated, any successor to the Indenture Trustee may authenticate such Environmental Control Bonds either in the name of any Retiring Indenture Trustee hereunder or in the name of the successor to the Indenture Trustee. Such certificates so authenticated shall have the full force and effect equal to any other Environmental Control Bond authenticated in accordance with the terms of this Indenture.

SECTION 6.10. Appointment of Co-Trustee or Separate Trustee. (a) Not-withstanding any other provisions of this Indenture, at any time, for the purpose of meeting any legal requirement of any jurisdiction in which any part of the Collateral may at the time be located, the Indenture Trustee shall have the power and may execute and deliver all instruments to appoint one or more Persons to act as a co-trustee or co-trustees, or separate trustee or separate trustees, of all or any part of the Collateral, and to vest in such Person or Persons, in such capacity and for the benefit of the Environmental Control Bondholders, such title to the Collateral, or any part hereof, and, subject to the other provisions of this Section, such powers, duties, obligations, rights and trusts as the Indenture Trustee may consider necessary or desirable. No co-trustee or separate trustee hereunder shall be required to meet the terms of

eligibility as a successor trustee under Section 6.11 and no notice to Environmental Control Bondholders of the appointment of any co-trustee or separate trustee shall be required under Section 6.08 hereof. Notes of any such appointment shall be promptly given to each Rating Agency and to the PSCWV by the Trustee.

(b) Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i) all rights, powers, duties and obligations conferred or imposed upon the Indenture Trustee shall be conferred or imposed upon and exercised or performed by the Indenture Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Indenture Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Indenture Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Collateral or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Indenture Trustee;

(ii) no trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder; and

(iii) the Indenture Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee.

(c) Any notice, request or other writing given to the Indenture Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Indenture and the conditions of this Article VI. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Indenture Trustee or separately, as may be provided therein, subject to all the provisions of this Indenture, specifically including every provision of this Indenture relating to the conduct of, affecting the liability of, or affording protection to, the Indenture Trustee. Every such instrument shall be filed with the Indenture Trustee.

(d) Any separate trustee or co-trustee may at any time constitute the Indenture Trustee, its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Indenture on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Indenture Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

Except as otherwise expressly provided herein, the Indenture Trustee may demand payment or delivery of, and shall receive and collect, directly and without intervention or assistance of any fiscal agent or other intermediary, all money and other property payable to or receivable by the Indenture Trustee pursuant to this Indenture. The Indenture Trustee shall apply all such money received by it as provided in this Indenture. Except as otherwise expressly provided in this Indenture, if any default occurs in the making of any payment or performance under any agreement or instrument that is part of the Collateral, the Indenture Trustee may take such action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate Proceedings. Any such action shall be without prejudice to any right to claim a Default or Event of Default under this Indenture and any right to proceed thereafter as provided in Article V.

SECTION 8.02. Collection Account. (a) On or prior to the Series Issuance Date for the first Series issued hereunder, the Issuer shall open, with the Indenture Trustee or with another Eligible Institution, one or more non-interest bearing segregated trust accounts in the Indenture Trustee’s name for the deposit of Environmental Control Charge Collections for such Series of Bonds and all other amounts received with respect to the Series Collateral servicing such Series of Bonds (each, a “Collection Account” and collectively, the “Collection Accounts”). The Indenture Trustee shall hold each Collection Account for the benefit of the related Environmental Control Bondholders, the Indenture Trustee and the other Persons indemnified hereunder. The Collection Account for each Series of Environmental Control Bonds will initially be divided into subaccounts, which need not be separate bank accounts: a general subaccount (each, a “General Subaccount”), a capital subaccount (each, a “Capital Subaccount”), an excess funds subaccount (each, an “Excess Funds Subaccount”) and a tranche subaccount for any Tranche of any Series that has a floating rate of interest as specified in any Series Supplement (each, a “Tranche Subaccount”).

Such Collection Account shall at all times be maintained in an Eligible Deposit Account and only the Indenture Trustee shall have access to such Collection Account for the purpose of making deposits in and withdrawals from such Collection Account in accordance with this Indenture. Funds in the Collection Account shall not be commingled with any other moneys, including moneys in any other Collection Account. All moneys deposited from time to time in a Collection Account, all deposits therein pursuant to this Indenture, and all investments made in Eligible Investments with such moneys, including all income or other gain from such investments, shall be held by the Indenture Trustee in such

Collection Account for such Series of Bonds as part of the Series Collateral securing such Bonds as herein provided. The Indenture Trustee shall have sole dominion and exclusive control over all moneys in such Collection Account and shall apply such amounts therein as provided in this Section 8.02.

The Securities Intermediary hereby confirms that (i) each Collection Account is, or at inception will be established as, a “securities account” as such term is defined in Section 8-501(a) of the UCC, (ii) it is a “securities intermediary” (as such term is defined in Section 8-102(a)(14) of the UCC) and is acting in such capacity with respect to such accounts, and (iii) the Indenture Trustee for the benefit of the Secured Parties is the sole “entitlement holder” (as such term is defined in Section 8-102(a)(7) of the UCC) with respect to such accounts and not other Person shall have the right to give “entitlement orders" (as such term is defined in Section 8-102(a)(8)) with respect to such accounts. The Securities Intermediary hereby further agrees that each item of property (whether investment property, financial asset, security, instrument or cash) received by it will be credited to the applicable Collection Account and shall be treated by it as “financial asset” within the meaning of Section 8-102(a)(9) of the UCC. Notwithstanding anything to the contrary, the State of West Virginia shall be deemed to be the jurisdiction of the Securities Intermediary for purposes of Section 8-110 of the UCC.

(b) All or a portion of the funds in each Collection Account shall be invested in Eligible Investments and reinvested by the Indenture Trustee at the written direction of the Servicer unless otherwise directed by Issuer Order; provided, however, that (i) such Eligible Investments shall not mature later than the Business Day prior to the next Payment Date for the related Series or Tranche, (ii) such Eligible Investments shall not be sold, liquidated or otherwise disposed of at a loss prior to the maturity thereof, and (iii) no funds in the Defeasance Subaccount for any Series of Environmental Control Bonds shall be invested in Eligible Investments or otherwise, except that U.S. Government Obligations deposited by the Issuer with the Indenture Trustee pursuant to Sections 4.01 or 4.02 shall remain as such. All income or other gain from investments of moneys deposited in each Collection Account shall be deposited by the Indenture Trustee in such Collection Account, and any loss resulting from such investments shall be charged to such Collection Account. The Issuer shall not direct the Indenture Trustee to make any investment of any funds or to sell any investment held in each Collection Account unless the security interest granted and perfected in such account will continue to be perfected in such investment or the proceeds of such sale, in either case without any further action by any Person, and, in connection with any direction to the Indenture Trustee to make any such investment or sale, if requested by the Indenture Trustee, the Issuer shall deliver to the Indenture Trustee an Opinion of Counsel, acceptable to the Indenture Trustee, to such effect. Subject to Section 6.01(c), the Indenture Trustee shall not in any way be held liable for the selection of Eligible Investments or for investment losses incurred thereon except for losses attributable to the Indenture Trustee’s failure to make payments on such Eligible Investments issued by the Indenture Trustee, in its commercial capacity as principal obligor and not as Indenture Trustee, in accordance with their terms. The Indenture Trustee shall have no liability in respect of losses incurred as a result of the liquidation of any Eligible Investment prior to its stated maturity or the failure of the Issuer to provide timely written investment direction. The Indenture Trustee shall have no obligation to invest or reinvest any amounts held hereunder in the absence of written investment direction pursuant to an Issuer Order. The Indenture Trustee is authorized to deposit uninvested funds in non-interest bearing, unsecured demand deposit accounts at affiliated banks,

purchase and sell investment securities through or from affiliated banks and broker-dealers, and invest funds in registered investment companies that receive investment management and custodial services from the Indenture Trustee or its affiliates. Except as otherwise provided hereunder, the Issuer shall retain the authority to institute, participate and join in any plan of reorganization, readjustment, merger or consolidation with respect to the issuer of securities held hereunder, and, in general, to exercise each and every other power or right with respect to each such asset or investment as individuals generally have and enjoy with respect to their own assets and investments, including power to vote upon any securities.

(c) Any Environmental Control Charge Collections, all investment earnings on the subaccounts in the Collection Account, and Indemnity Amounts remitted to the Indenture Trustee by the Transferor, the Seller or the Servicer or otherwise received by the Indenture Trustee, any other proceeds of Collateral received by the Servicer, the Issuer or the Indenture Trustee and any amounts paid by any Swap Counterparty under a Swap Agreement received by the Servicer, the Issuer or the Indenture Trustee, shall be deposited in the General Subaccount.

(d) On the Business Day preceding the Payment Date, the Indenture Trustee, at the written direction of the Servicer, shall allocate to each Tranche Subaccount the amounts specified in the related Series Supplement. Such amounts shall be so allocated after taking into account all allocations and payments required in connection with such Payment Date under clauses (e)(i) through (v) below; provided that in the event of any shortfall of amounts to be allocated pursuant to clause (e)(v) among more than one Tranche of the applicable Series amounts shall be allocated pursuant to clause (e)(v) among more than one Tranche of the applicable Series, amounts shall be allocated to such Tranche Subaccount on a Pro Rata basis with all other Tranches of the relevant Series. Amounts in each Tranche Subaccount shall be applied as provided in the related Series Supplement.

(e) On each Payment Date for any Series of Bonds, or before each Payment Date to the extent otherwise specified in the related Series Supplement with respect to any Tranche Subaccount, or if such day is not a Business Day, on the following Business Day, the Indenture Trustee shall, at the written direction of the Servicer as set forth in an Officer’s Certificate delivered to the Indenture Trustee in accordance with Section 5.12 of the Servicing Agreement, apply all amounts on deposit in the General Subaccount of the Collection Account for a particular Series of Bonds and any investment earnings on the Subaccounts in the Collection Account, after allocating to any Tranche Subaccount in accordance with clause (d) above and the related payment to each Swap Counterparty in accordance with the related Series Supplement, and in the following priority:

(i) to the Indenture Trustee, all amounts due and owing to the Indenture Trustee (or the allocable share of such amounts, if Additional Bonds are Outstanding) as of such Payment Date (including any Indemnity Amounts);

(ii) to the Servicer, the Servicing Fee for such Payment Date and all unpaid Servicing Fees from prior Payment Dates (or the allocable share of such Servicing Fees, if Additional Bonds are Outstanding) shall be paid to the Servicer;

(iii) to the Administrator, the Administrative Fee payable on such Payment Date under the Issuer Administration Agreement (or the allocable share of such Administrative Fee, if Additional Bonds are Outstanding), together with any unpaid Administrative Fees from prior Payment Dates, and to the Independent Managers, their fees in an amount equal to $1,000 plus expenses for such Payment Date, together with any unpaid fees from prior Payment Dates;

(iv) so long as no Event of Default has occurred and is continuing or would be caused by such payment, all Operating Expenses (including the allocable share of all Operating Expenses not directly attributable to the Bonds or the trusts administered hereunder) other than distributions made in accordance with clauses (i), (ii) and (iii) above shall be paid to the Persons entitled thereto;

(v) an amount equal to the sum of (1) the interest then due and owing on such Payment Date with respect to such Series of Bonds, (2) any amount in respect of periodic payments that are required to be made to any Swap Counterparty on any Swap Agreement with respect to any Floating Rate Bonds and (3) any deferred interest on any Floating Rate Bonds;

(vi) payment of the principal due and payable on each Tranche of the Bonds of all Series as a result of (1) Final Maturity Date, (2) any acceleration under Section 5.02, (3) payment of the principal due and payable on each Tranche of Bonds according to the Expected Sinking Fund Schedule, and (4) any Swap Termination Payments that result from (a) the failure of the Issuer to pay any amount due under the applicable Swap Agreement within five Business Days, (b) any breach of any Swap Agreement by the Issuer or the Indenture Trustee where the applicable Swap Counterparty is not the defaulting party or the solely affected party, (c) any Issuer Bankruptcy, (d) any merger or consolidation of the Issuer where no successor assumes the Issuer’s liabilities under the related Swap Agreement, (e) any failure or termination of the security interest under this Indenture or (f) termination of any Swap Agreement as a result of a tax event, any illegality, a tax event upon merger, any acceleration of the Bonds under Section 5.02 following an event of default or a change in the applicable laws that makes any Swap Agreement unenforceable;

(vii) all remaining unpaid Operating Expenses (or the allocable share of such Operating Expenses if Additional Bonds are Outstanding) and Indemnity Amounts shall be paid to the Persons entitled thereto;

(viii) any amount necessary to replenish any shortfalls in the Capital Subaccount below the Required Capital Amount shall be allocated to the Capital Subaccount;

(ix) after the payment of the Bonds in full, any other payments required to be paid under any Swap Agreement as specified in the related Swap Agreement shall be paid to the respective Swap Counterparty, excluding such payments made pursuant to clauses (v) or (vi), above or a Senior Termination Event (as such term is defined in the applicable Swap Agreement);

(x) provided that no Event of Default has occurred and is continuing, an amount up to the amount of the Capital Equity Return (including any portion of the Capital Equity Return for a prior Payment Date that has not yet been paid) will be released to the Seller, free from the lien of this Indenture; and

(xi) the balance, if any, shall be allocated to the Excess Funds Subaccount.

(f) “Pro Rata” means with respect to the Bonds or any Tranche of Bonds, the ratio (i) in the case of clause (e)(v) above, the numerator of which is the aggregate amount of Interest payable or net amount payable to a Swap Counterparty under any Swap Agreement with respect to the Bonds or such Tranche on such Payment Date and the denominator of which is the sum of the aggregate amounts of interest payable and aggregate of the net amounts payable under all Swap Agreements with respect to the Bonds or such Tranche; and (ii) in the case of other clauses in clause (e) above, the numerator of which is the aggregate amount of principal scheduled to be paid or payable on such Payment Date with respect to all Bonds or any Tranche of Bonds on such Payment Date and the denominator of which is the sum of the aggregate amounts of principal scheduled to be paid or payable with respect to all Outstanding Tranches on such Payment Date.

(g) If, on any Payment Date with respect to all Outstanding Tranches of any Series, funds on deposit in the General Subaccount (and, with respect to interest on the Bonds with a floating rate of interest, the Tranche Subaccount for that Tranche of Bonds other than amounts relating to Swap Termination Payments) are insufficient to make the payments and allocations contemplated by subclauses (e)(i) through (xi) above or by subclauses (h)(i) through (iv), for the Bonds, the Indenture Trustee shall, at the direction of the Servicer, draw from amounts on deposit in the following Subaccounts in the following order up to the amount of such shortfall, in order to make such payments and allocations:

(i) from the Excess Funds Subaccount, Pro Rata, for payments and allocations contemplated by subclauses (e)(i) through (ix) and subclauses (h)(i) through (iv); and

(ii) from the Capital Subaccount, Pro Rata, for payments and allocations contemplated by subclauses (e)(i) through (vii) and subclauses (h)(i) through (iv);

provided that no amounts from the Excess Funds Subaccount or the Capital Subaccount shall be allocated to any Tranche Subaccount pursuant to subclause (e)(v) to the extent a shortfall in amounts available to pay interest due on the related Floating Rate Bonds is caused solely by a failure by a Swap Counterparty to make payments due under the related Swap Agreement.

(h) On each Payment Date on which Interest payments are to be made in respect of Bonds with a floating rate of interest but not in respect to Bonds with a fixed rate of interest in accordance with the applicable Series Supplement, the Trustee will allocate or pay all amounts on deposit in the General Subaccount (and, with respect to interest on the Bonds with a floating rate of interest, the Tranche Subaccount for that Tranche of Bonds other than amounts

relating to Swap Termination Payments) of the Collection Account for the Floating Rate Bonds in the following priority, at the direction of the Servicer as set forth in an Officer’s Certificate of the Servicer:

(i) to the Indenture Trustee all amounts due and owing the Indenture Trustee (or the allocable share of such Operating Expenses, if Additional Bonds are Outstanding) as of such Payment Date and any outstanding Indemnity Amounts;

(ii) to the Servicer all unpaid Servicing Fees from prior Payment Dates (or the allocable share of such Operating Expenses, if Additional Bonds are Outstanding) shall be paid to the Servicer;

(iii) all remaining unpaid Operating Expenses (or the allocable share of such Operating Expenses if Additional Bonds are Outstanding);

(iv) an amount equal to the sum of (1) the interest then due and owing on such Payment Date and (2) any amount in respect of periodic payments that are required to be made to any Swap Counterparty on any Swap Agreement with respect to any Floating Rate Bonds; payment of the Interest then payable on the Floating Rate Bonds, amounts payable in respect of interest to the Swap Counterparty under any Swap Agreement and any deferred interest on any Floating Rate Bonds, and

(v) the balance, if any, shall be allocated to the General Subaccount.

(i) Notwithstanding any other provision in this Indenture to the contrary, upon an acceleration of the maturity of the Bonds pursuant to Section 5.02, the aggregate amount of principal of and interest accrued on each Bond shall be payable, without priority of interest over principal or of principal over interest and without regard to Tranche, in the proportion that the aggregate amount of principal of and interest accrued on such Bond bears to the aggregate amount of principal of and interest accrued on all Bonds.

(j) Notwithstanding any other provision in this Indenture to the contrary, in the event of an acceleration of the maturity of Environmental Control Bonds and a subsequent liquidation of the Collateral in accordance with Section 5.04(a), if so required by any Swap Agreement, the proceeds of such liquidation allocated to the related Tranche of Floating Rate Bonds in accordance with this Section 8.02 shall be deposited in the related Tranche Subaccount and allocated between and paid to the Holders of the related Floating Rate Bonds, on the one hand, and the related Swap Counterparty, on the other hand, Pro Rata based on the aggregate amount of Principal and interest due and payable on such Tranche of Floating Rate Bonds and the aggregate amount payable to the related Swap Counterparty in accordance with such Swap Agreement.

SECTION 8.03. Release of Collateral. (a) All money and other property withdrawn from the Collection Account by the Indenture Trustee for payment to the Issuer as provided in this Indenture in accordance with Section 8.02 hereof shall be deemed released from the Indenture when so withdrawn and applied in accordance with the provisions of Article VIII, without further notice to, or release or consent by, the Indenture Trustee.

(b) So long as the Issuer is not in default hereunder, the Issuer, through the Servicer, may collect, liquidate, sell or otherwise dispose of the Transferred Environmental Control Property, at any time and from time to time, without any notice to, or release or consent by, the Indenture Trustee, but only as and to the extent permitted by the Basic Documents; provided, however, that any and all proceeds of such dispositions shall become Collateral and be deposited to the General Subaccount immediately upon receipt thereof by the Issuer or any other Person, including the Servicer.

(c) Other than as provided for in clauses (a) and (b) above, the Indenture Trustee shall release property from the lien of this Indenture only as and to the extent permitted by the Basic Documents and only upon receipt of an Issuer Request accompanied by an Officer’s Certificate, an Opinion of Counsel and Independent Certificates in accordance with TIA § 314(c) and 314(d)(1) meeting the applicable requirements of Section 11.01 or an Opinion of Counsel in lieu of such Independent Certificates to the effect that the TIA does not require any such Independent Certificate.

(d) Subject to the payment of its fees and expenses pursuant to Section 6.07, the Indenture Trustee may, and when required by the provisions of this Indenture shall, execute instruments to release property from the lien of this Indenture, or convey the Indenture Trustee’s interest in the same, in a manner and under circumstances that are not inconsistent with the provisions of this Indenture. No party relying upon an instrument executed by the Indenture Trustee as provided in this Article VIII shall be bound to ascertain the Indenture Trustee’s authority, inquire into the satisfaction of any conditions precedent or see to the application of any moneys.

(e) Subject to Section 8.03(c), the Indenture Trustee shall, at such time as there are no Environmental Control Bonds Outstanding and all sums due the Indenture Trustee pursuant to Section 6.07 have been paid, release any remaining portion of the Series Collateral that secured the Environmental Control Bonds from the lien of this Indenture and release to the Issuer or any other Person entitled thereto any funds then on deposit in the Collection Account.

SECTION 8.04. Opinion of Counsel. The Indenture Trustee shall receive at least five Business Days written notice when requested by the Issuer to take any action pursuant to Section 8.03, accompanied by copies of any instruments involved, and the Indenture Trustee shall also require, as a condition to such action, an Opinion of Counsel, in form and substance satisfactory to the Indenture Trustee, stating the legal effect of any such action, outlining the steps required to complete the same, and concluding that all conditions precedent to the taking of such action have been complied with and such action will not materially and adversely impair the security for the Environmental Control Bonds or the rights of the Environmental Control Bondholders in contravention of the provisions of this Indenture; provided, however, that such Opinion of Counsel shall not be required to express an opinion as to the fair value of the Collateral. Counsel rendering any such opinion may rely, without independent investigation, on the accuracy and validity of any certificate or other instrument delivered to the Indenture Trustee in connection with any such action.

SECTION 8.05. Reports by Independent Accountants. The Issuer shall appoint a firm of Independent registered public accountants of recognized national reputation for

purposes of preparing and delivering the reports or certificates of such accountants required by this Indenture and the related Series Supplements.

If the Issuer shall not have appointed a successor within ten days thereafter the Indenture Trustee shall promptly appoint a successor firm of Independent registered public accountants of recognized national reputation. The fees of such firm of Independent registered public accountants and its successor shall be payable by the Issuer.

In case it shall be impractical to deliver notice in accordance with the first paragraph of this Section 11.05 to the Holders of Environmental Control Bonds when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.

Where this Indenture provides for notice to the Rating Agencies, failure to give such notice shall not affect any other rights or obligations created hereunder, and shall not under any circumstance constitute a Default or Event of Default.

SECTION 11.06. Alternate Payment and Notice Provisions.

SECTION 11.12. Legal Holidays. In any case where the date on which any payment is due shall not be a Business Day, then (notwithstanding any other provision of the Environmental Control Bonds or this Indenture) payment need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date on which nominally due, and no interest shall accrue for the period from and after any such nominal date.

SECTION 11.13. GOVERNING LAW. THIS INDENTURE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS, PROVIDED THAT THE LAWS OF THE STATE OF WEST VIRGINIA SHALL GOVERN THE CREATION, ATTACHMENT, PERFECTION AND ENFORCEMENT OF THE SECURITY INTEREST HEREUNDER IN THE TRANSFERRED ENVIRONMENTAL CONTROL PROPERTY UNDER THE STATUTE.

SECTION 11.17. Customer Identification. To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account.

(a) Upon a termination event or event of default under the Tranche [ ] Swap Agreement, the Issuer shall appoint a recognized swap dealer which is a member of the International Swaps and Derivatives Association, Inc. with capital and surplus of at least $50 million (the "Swap Agent") to independently solicit, for a period not exceeding 30 days, a replacement Tranche [ ] Swap Counterparty (a "Replacement Counterparty"), who shall not be the Swap Agent or an Affiliate thereof. During such 30 day period, the Swap Agent shall be required to identify a Qualified Replacement Counterparty, or if a Qualified Replacement Counterparty cannot be found, the Swap Agent shall be required to identify the highest rated Replacement Counterparty available that is approved by the Holders of at least 66 2/3% of the Outstanding Amount of the [Floating Rate Tranche] (an "Approved Replacement Counterparty"). In any case, if there is more than one available Qualified Replacement Counterparty or Approved Replacement Counterparty, as applicable, with the same credit rating, the Swap Agent shall select that prospective Qualified Replacement Counterparty or Approved Replacement Counterparty, as applicable, offering the terms with the lowest overall cost to the Issuer. The costs and expenses of a Swap Agent appointed pursuant to this Section 9(a) shall be an Operating Expense to be paid by the Issuer pursuant to Section 8.02(e)(iv), to the extent not paid by the Swap Counterparty .

(b) If the Swap Agent is successful in identifying a Qualified Replacement Counterparty or Approved Replacement Counterparty, upon the termination of the Tranche [ ] Swap Agreement, the Issuer shall execute a replacement Tranche [ ] Swap Agreement with such Replacement Counterparty having substantially the same terms as the Tranche [ ] Swap Agreement being replaced, effective as of the Payment Date immediately following such execution. Any initial upfront payments made by such Replacement Counterparty in connection with its entering into such replacement Tranche [ ] Swap Agreement shall be paid to the terminated Tranche [ ] Swap Counterparty, and any termination payment or other similar amount paid to the Issuer by the terminated Tranche [ ] Swap Counterparty in accordance with the terms of the Swap Agreement shall first be used to make any payment required to be made to a Replacement Counterparty under a Swap Agreement and then to the extent not so used shall be deposited into the Tranche [ ] Subaccount and paid to the Holders of the [Floating Rate Tranche] on the next Payment Date, pro rata based on the principal amount held by each Holder.

(c) If a Qualified Replacement Counterparty or an Approved Replacement Counterparty has not been obtained, the Swap Agent shall be required to renew such search every three months thereafter until a Qualified Replacement Counterparty or Approved

Replacement Counterparty has been identified and approved and a replacement Tranche [ ] Swap Agreement has been entered into in the manner set forth in clauses (a) and (b) above.

(d) If a termination event or a event of default occurs and is continuing under the Tranche [ ] Swap Agreement, the Indenture Trustee may, and at the direction of the Holders of at least 66 2/3% of the Outstanding Amount of the [Floating Rate Tranche] shall, exercise all rights, remedies, powers, privileges and claims of the Issuer against the Tranche [ ] Swap Counterparty and any right of the Issuer to take this action shall be suspended.

(e) The Tranche [ ] Swap Agreement may be amended in accordance with the terms of the Indenture.

(f) With respect to any action proposed by the Issuer to amend, modify, waive, supplement or surrender the terms of or rights under the Tranche [ ] Swap Agreement, or waive timely performance or observance by the Tranche [ ] Swap Counterparty under the Tranche [ ] Swap Agreement, in a way which would materially and adversely affect the interests of the Holders of the [Floating Rate Tranche], the Issuer shall provide prior notice to the Rating Agencies. The Issuer will consent to such proposed action only with the consent of (i) the Holders of at least 66 2/3% of the Outstanding Amount of the [Floating Rate Tranche] and (ii) the Holders of at least 66 2/3% of the Outstanding Amount of all of such other Series or Tranches, and each counterparty to any other Swap Agreement, materially and adversely affected thereby. Notwithstanding the foregoing, nothing shall prevent the Issuer from seeking or retaining a Swap Agent to seek a Replacement Counterparty.

(g) Notwithstanding the foregoing clause (f), upon a Swap Counterparty Downgrade Event or payment default by the Tranche [ ] Swap Counterparty under the Tranche [ ] Swap Agreement, the Issuer shall not (i) continue with a downgraded Tranche [ ] Counterparty notwithstanding the failure timely to identify a Qualified Replacement Counterparty or Approved Replacement Counterparty, as provided in the Tranche [ ] Swap Agreement, or (ii) waive a payment default by the Tranche [ ] Swap Counterparty within the time periods prescribed in the Tranche [ ] Swap Agreement, except as directed by the Holders of at least 66 2/3% of the Outstanding Amount of the [Floating Rate Tranche].]

SCHEDULE B

Calculation of LIBOR

(a) On the Tranche [ ] Interest Determination Date immediately preceding the first day of each applicable Calculation Period, the Indenture Trustee will determine LIBOR based on the offered rate for deposits in United States dollars for the applicable period, commencing on the first day of that Calculation Period that appears on the Moneyline Telerate Service page 3750 of the Telerate Services as of 11:00 a.m., London time, on such Tranche [ ] Interest Determination Date (the "Telerate Page"). If no offered rate appears on the Telerate Page, LIBOR for such Calculation Period will be determined as described in clause (b) below.

(b) With respect to an Tranche [ ] Interest Determination Date on which no offered rate appears on the Telerate Page, the Indenture Trustee will request each of four major banks in the London interbank market, selected by the Indenture Trustee, to provide the Indenture Trustee with that bank’s offered quotation for deposits in United States dollars for the applicable Calculation Period, commencing on the second London Banking Day immediately following that Tranche [ ] Interest Determination Date, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on such Tranche [ ] Interest Determination Date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time for the applicable period. If at least two such quotations are provided, LIBOR for such Calculation Period will be the arithmetic mean of those quotations. If fewer than two quotations are provided, LIBOR for that Calculation Period will be the arithmetic mean of the rates quoted at approximately 11:00 a.m. in the City of New York, on that Tranche [ ] Interest Determination Date by major banks in the City of New York selected by the Indenture Trustee for loans in United States dollars to leading European banks, for the Calculation Period commencing on the second London Banking Day immediately following that Tranche [ ] Interest Determination Date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time.

(c) On the first Tranche [ ] Interest Determination Date, the Indenture Trustee will determine three-month LIBOR as described above and will also determine LIBOR based on the offered rate for six-month deposits in United States dollars that appears on the Telerate page or, if no such offered rate appears on the Telerate page, in the manner described in (b) above (except that the “applicable period” will be six months). The interpolated LIBOR applicable to the first interest accrual period will be equal to the sum of (a) three-month LIBOR and (b) the LIBOR increment. The LIBOR increment will be equal to the product of (x) a fraction, the numerator of which is the actual number of days from and including the three-month anniversary of the closing date to but excluding the first payment date and the denominator of which is 90, and (y) the excess, if any, of six-month LIBOR over three-month LIBOR.

(d) If LIBOR cannot be determined in accordance with clauses (a), (b) or (c) above, then LIBOR will be determined to be the same as the rate which applied during the previous Calculation Period or, in the case of any failure to determine LIBOR on either of the two Tranche [ ] Interest Determination Dates preceding the first Payment Date, the rate which is on the Series Issuance Date.
