(ii) If the Trustee does not receive all of the Overdue Amounts and the applicable Special Facility Fee, and the Trust has received notice for the exercise of the Issuance Right for the entire Available Amount for settlement within 30 days following such Distribution Date pursuant to the Facility Agreement, and no Trust Dissolution Date shall have occurred (in which event the procedures in Section 8.1(b) shall apply), as provided in the Facility Agreement (A) the Trust shall purchase the Senior Secured Notes issued by Vistra Operations (or in the case of any Cash Settlement Election, shall receive the applicable Cash Settlement Amount) in exchange for the Notes Purchase Price, (B) the applicable Special Facility Fee shall be due and payable and (C) payment by the Trust of the Notes Purchase Price shall be subject to set-off against any Overdue Amounts and Special Facility Fee (with the Eligible Assets included in the Notes Purchase Price being valued for the purpose of such set-off based on the proceeds received therefor by the Trust). The Trust shall have the power to liquidate Eligible Assets and any Substitute Deposits held by the Trust to cover such Overdue Amounts and Special Facility Fee, together with any Trust Expenses reasonably incurred in such liquidation or any other due and unpaid amounts specified in Section 5.8(b)(1) or (2), and, if the proceeds of such liquidation of Eligible Assets and Substitute Deposits are insufficient to cover any due and unpaid amounts specified in Section 5.8(b)(i)(1) or (2), to liquidate any Senior Secured Notes then held by the Trust. Any liquidation of Eligible Assets, Substitute Deposits or Senior Secured Notes shall be done in accordance with the provisions set forth in Section 5.9, and the Trustee shall distribute, on the Business Day following receipt, all such proceeds of such liquidation in accordance with this Declaration and the priorities specified in Section 5.8(b); provided that such Distribution shall be payable to the Holders of the Trust Securities as of the close of business on the Business Day immediately preceding the date of Distribution.

(iii) If the Trustee does not receive all of the Overdue Amounts and the applicable Special Facility Fee, and the Trust has not received notice for the exercise of the Issuance Right for the entire Available Amount for settlement within 30 days following such Distribution Date, an Automatic Exercise Event shall occur pursuant to the Facility Agreement and the provisions of Article VIII shall apply.

(e) In any year in which a Distribution Date is not a Business Day, the payment with respect to such Distribution Date shall be made on the following Business Day. The postponement of any payment with respect to such Distribution shall not affect the amount of any payment that Vistra Operations or the Trust is required to make on such Distribution Date.

-49-

(f) Notwithstanding anything to the contrary in this Declaration, if any Trust Expenses are due and payable by the Trust on a date that is not a Distribution Date, the Trust shall pay such Trust Expenses prior to the next Distribution Date out of any advance received from Vistra Operations pursuant to the Trust Expense Reimbursement Agreement.

(g) On each date on which a Distribution is made pursuant to this Section 5.8, the Trustee shall provide written confirmation to Vistra Operations of the Trust Income received by the Trust that is distributed on such date, as well as the amount of Distributions made to the Holders on such date. The Trustee shall provide each Rating Agency a copy of such written confirmation.

Section 5.9. Liquidation of Eligible Assets and Senior Secured Notes.

(a) If the Trust is entitled to liquidate any Trust Property pursuant to Section 5.8(d):

(i) The Trustee shall first apply all Trust Income available on such date and any other funds available in the Property Account (including any Substitute Deposits) on the relevant date to make payments in respect of such Trust Expenses or any other expenses on such date in accordance with the priorities set forth in Section 5.8(b).

(ii) To the extent that the funds available in the Property Account and any Eligible Assets that can be set-off against the relevant expenses pursuant to Section 5.8 are insufficient to pay any due and unpaid amounts specified in Section 5.8(b)(i)(1) or (2), the Trustee, or agent, shall liquidate Eligible Assets in the open market, to the extent necessary for the proceeds to cover such due and unpaid amounts. The Trustee shall have no liability with respect to the adequacy of the price received in connection with said liquidation. The Eligible Assets to be liquidated shall be pro rata between Treasuries and each series of STRIPS comprising the Eligible Assets, in each case rounded to the nearest $1,000 in principal/face amount.

(iii) To the extent that the proceeds from the liquidation of Eligible Assets are insufficient to cover any due and unpaid amounts specified in Section 5.8(b)(i)(1) or (2) and the Trust holds any Senior Secured Notes, the Trust shall liquidate Senior Secured Notes in the open market, to the extent necessary for the proceeds to cover such due and unpaid amounts. Any liquidation of Senior Secured Notes will be made in accordance with commercially reasonable market standards, which may include retaining third-party agents at the expense of the Trust, and in compliance with applicable securities laws. The Trustee shall not be liable for the adequacy or sufficiency of the price obtained for such liquidation of Senior Secured Notes.

(b) Not later than 3:00 p.m. on the Business Day following its receipt of proceeds of all Trust Property to be liquidated pursuant to Section 5.9(a), the Trustee shall distribute such proceeds in accordance with the priorities specified in Section 5.8(b); provided that such Distribution shall be payable to the Holders of the Trust Securities as of the close of business on the Business Day immediately preceding the date of such Distribution.

Section 5.10. Redemption.

(a) Subject to applicable law, upon the redemption by Vistra Operations of any Senior Secured Notes held by the Trust or any Voluntary Exercise for any Senior Secured Notes as to which Vistra Operations has made a Cash Settlement Election, the Trust shall redeem a Like Amount of Trust Securities at the Redemption Price on the Vistra Operations Payment Date, subject to the priorities of distribution set forth in Section 8.2(c); provided that (i) if the Vistra Operations Payment Date is the Trust Dissolution Date, the Vistra Operations Payment shall be distributed in accordance with Article VIII, and (ii) if the Trustee does not receive the Vistra Operations Payment prior to 12:00 p.m. on the Vistra Operations Payment Date, such Trust Securities shall be redeemed on the Business Day following the day the Trustee receives the Vistra Operations Payment.

(b) Vistra Operations shall provide a notice of redemption to the Trustee containing the information listed below, and, based solely on the information provided in such notice, a notice of redemption of the Trust Securities shall be given by the Trustee by first-class mail, postage prepaid, mailed not less than 10 nor more than 60 days prior to the Redemption Date to each Holder of Trust Securities to be redeemed, at such Holder’s address appearing in the Register. Each notice of redemption shall state:

(i) the Redemption Date;

(ii) the Redemption Price or, if the Redemption Price cannot be calculated prior to the time the notice is required to be sent, a description of the manner in which the Redemption Price shall be determined;

(iii) the CUSIP number or CUSIP numbers of the Trust Securities affected;

(iv) if less than all the Outstanding Trust Securities are to be redeemed, the identification and the aggregate initial purchase price of the particular Trust Securities to be redeemed;

(v) that on the Redemption Date the Redemption Price will become due and payable upon each such Trust Security to be redeemed and that Distributions thereon will cease to accumulate on and after said date, except as provided in Section 5.10(d); and

(vi) if the Trust Securities are no longer in book-entry-only form, the place or places where the Certificates are to be surrendered for the payment of the Redemption Price.

(c) The Trust Securities redeemed on each Redemption Date shall be redeemed at the Redemption Price with the Vistra Operations Payment to be received on the Redemption Date. Redemptions of the Trust Securities shall be made and the Redemption Price shall be payable on each Redemption Date only to the extent that the Trust has received such Vistra Operations Payment.

-51-

(d) If the Trustee gives a notice of redemption in respect of any Trust Securities, then, by 12:00 p.m., on the Redemption Date, subject to Section 5.10(c), the Trustee shall, with respect to Trust Securities represented by Global Certificates, irrevocably deposit with DTC, to the extent available therefor, funds sufficient to pay the applicable Redemption Price and shall give DTC irrevocable instructions and authority to pay the Redemption Price to the Holders. With respect to Trust Securities that are not represented by Global Certificates, the Trustee, subject to Section 5.10(c), shall irrevocably deposit with the Paying Agent, to the extent available therefor, funds sufficient to pay the applicable Redemption Price and shall give the Paying Agent irrevocable instructions and authority to pay the Redemption Price to the Holders upon surrender of their Certificates. Notwithstanding the foregoing, Distributions payable on or prior to the Redemption Date for any Trust Securities called for redemption shall be payable to the Holders of such Trust Securities as they appear on the Register for the Trust Securities on the relevant Record Dates for the related Distribution Dates. If notice of redemption shall have been given and funds deposited as required, then upon the date of such deposit, all rights of Holders of Trust Securities so called for redemption shall cease, except the right of such Holders to receive the Redemption Price and any Distribution payable in respect of the Trust Securities on or prior to the Redemption Date, but without interest, and such Trust Securities shall cease to be Outstanding. In the event that the Redemption Date is not a Business Day, then payment of the Redemption Price payable on such date shall be made on the next succeeding day that is a Business Day (without any interest or other payment in respect of any such delay), with the same force and effect as if made on such date.

(e) If less than all the Outstanding Trust Securities are to be redeemed on a Redemption Date, the particular Trust Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Trust Securities not previously called for redemption on a pro rata basis or by any method the Trustee deems fair and appropriate; provided that so long as the Trust Securities are represented by Global Certificates, such selection shall be made in accordance with the procedures of the Depositary in accordance with its standard procedures therefor. The Trustee shall promptly notify the Security Registrar in writing of the Trust Securities selected for redemption.

(f) Vistra Operations shall give written notice to the Trustee of any Vistra Operations Payment Date at least 30 days but not more than 60 days prior thereto (unless a shorter notice shall be satisfactory to the Trustee).

Section 5.11. No Preemptive Rights. No Holder, by virtue of holding Trust Securities, shall have any preemptive or other right to subscribe to any additional Trust Securities.

Section 5.12. Status of the Trust Securities. Every Holder, by virtue of having become a Holder, shall be deemed to have expressly assented and agreed to the terms hereof and to have become party hereto. The Trust Securities shall be deemed to be personal property, giving only the rights provided herein. Ownership of the Trust Securities shall not entitle the Holder to any title in, or to the whole or any part of, the Trust Property or right to call for a partition or division of the same or for an accounting. The bankruptcy of a Holder during the continuance of the Trust shall not operate to terminate the Trust, nor entitle the representative of any bankrupt Holder to an accounting or to take any action in court or elsewhere against the Trust or the Trustee.

-52-

Section 5.13. CUSIP Numbers. The Trust, in issuing the Trust Securities, may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of dissolution as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Trust Securities or as contained in any notice of a dissolution and that reliance may be placed only on the other identification numbers printed on the Trust Securities, and any such dissolution shall not be affected by any defect in or omission of such numbers.

Section 5.14. Lists of Holders.

(a) The Transfer Agent (if the Trustee is not acting in such capacity) shall provide the Trustee (i) by the end of the fourth Business Day after each Record Date, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders (a “List of Holders”) as of such Record Date, provided that the Transfer Agent shall not be obligated to provide such List of Holders if at any time the List of Holders does not differ from the most recent List of Holders given to the Trustee by the Transfer Agent, and (ii) a List of Holders at any time the Trustee requests a List of Holders, which List of Holders shall be provided to the Trustee by the Transfer Agent within 30 days of the Trustee delivering a written request for the List of Holders to the Transfer Agent, and which shall be no more than four Business Days old on the date it is delivered to the Trustee. The Trustee shall preserve, in as current a form as is reasonably practicable, all information contained in any List of Holders given to it or that it receives in its capacity as Paying Agent (if acting in such capacity), provided that the Trustee may destroy any List of Holders previously given to it on receipt of a new List of Holders.

(b) The Trustee shall comply with the requirements of Section 312(b) of the Trust Indenture Act, as if the Trust Indenture Act applied to this Declaration.

Section 5.15. No Other Rights. Unless otherwise required by law, the Holders of Trust Securities shall not have any rights or preferences other than those specifically set forth in this Declaration and in the Certificates.

Section 5.16. Global Certificates. The provisions of this Section 5.16 shall apply only to Global Certificates:

(a) Each Global Certificate executed and delivered under this Declaration shall be registered in the name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Certificate shall constitute a single Certificate for all purposes of this Declaration.

(b) If any Depositary elects to discontinue its services as securities depositary with respect to the Trust Securities, the Trustee may appoint a successor Depositary at the written direction of Vistra Operations with respect to the Trust Securities.

-53-

(c) Notwithstanding any other provision in this Declaration, no Global Certificate may be exchanged in whole or in part for Certificates registered, and no transfer of a Global Certificate in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Certificate or a nominee thereof unless (i) such Depositary has notified the Trust that it is unwilling or unable to continue as Depositary for such Global Certificate and no successor depositary shall have been appointed by the Trust within 90 days of such notice, (ii) if at any time such Depositary has ceased to be a clearing agency registered under the Exchange Act at a time when such Depositary is required to be so registered to act as Depositary and no successor depositary shall have been appointed by the Trust within 90 days after the Trust becomes aware of such cessation, or (iii) the Trustee voluntarily elects to discontinue the use of the book-entry transfer system with the consent of at least a Majority of Holders. If Global Certificates are exchanged pursuant to this Section 5.16(c), Distributions may, at the Trust’s option, be paid by check mailed to the Persons entitled thereto as shown on the Register. Notwithstanding the foregoing, a Holder of 1,000 or more Trust Securities shall be entitled to receive Distributions, if any, on any Distribution Date by wire transfer of immediately available funds if appropriate wire transfer instructions have been received in writing by the Trust not less than 15 days prior to the Distribution Date. Any such wire transfer instructions received by the Trust shall remain in effect until revoked by such Holder.

(d) Subject to Section 5.16(c), any exchange of a Global Certificate for other Certificates may be made in whole or in part, and all Certificates issued in exchange for a Global Certificate or any portion thereof shall be registered in such names as the Depositary for such Global Certificate shall direct.

(e) Every Certificate executed and delivered upon registration of, transfer of, or in exchange for or in lieu of, a Global Certificate or any portion thereof, whether pursuant to this Section 5.16 or otherwise, shall be executed and delivered in the form of, and shall be, a Global Certificate, unless such Certificate is registered in the name of a Person other than the Depositary for such Global Certificate or a nominee thereof.

(b) Change of Control Offer. Within 30 days following its receipt of notice of any Change of Control Trigger Event, the Trustee will mail (or deliver electronically) a notice (the “Change of Control Offer”) prepared by Vistra Operations to each holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase Trust Securities on the date specified in the notice (the “Change of Control Payment Date”), which date will be no earlier than 10 days and no later than 60 days from the date such notice is mailed or delivered, pursuant to the procedures required by this Section 5.17 and described in such notice. Holders of the Trust Securities electing to have any Trust Securities purchased pursuant to a Change of Control Offer (as evidenced by their surrender) shall be required to surrender the Trust Securities to the paying agent on the third Business Day preceding the Change of Control Payment Date (the “Change of Control Offer Expiration Date”). Vistra Operations and the Trust will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Trust Securities as a result of a Change of Control Trigger Event. To the extent that the provisions of any securities laws or regulations conflict with provisions of the Senior Secured Notes Indenture, Vistra Operations and the Trust will comply with the applicable securities laws and regulations and will not be deemed to have breached their obligations under this Section 5.17 by virtue of such compliance as evidenced by an Officer’s Certificate delivered to the Trustee.

(c) In the Change of Control Offer, the Trust, at the written direction of Vistra Operations, and subject to the receipt from Vistra Operations of the change of control payment with respect to the relevant Senior Secured Notes plus (which such payment may be made directly to the Trust to the extent no Senior Secured Note is held through the facilities of a depository, and all such Senior Secured Notes are held in the name of the Trust), to the extent Vistra Operations elects to pay the Cash Settlement Amount with respect to the Change of Control Offer Subject Amount, such Cash Settlement Amount, will offer a payment in cash equal to 101% of the aggregate initial purchase price of the Trust Securities, plus accrued and unpaid distributions, if any, on the Trust Securities to the date of repurchase, subject to the rights of holders of the Trust Securities on the relevant record date to receive distributions on the relevant Distribution Date (the “Change of Control Payment”).

(d) If the Senior Secured Notes with respect to which Vistra Operations has made a change of control offer under the Senior Secured Notes Indenture are then held by the Trust (including any Senior Secured Notes to be issued to the Trust pursuant to a Mandatory Exercise as described below), Vistra Operations will notify the Trust and the Senior Secured Notes Trustee of the change of control triggering event under the Senior Secured Notes Indenture and the Senior Secured Notes Trustee will accept such change of control offer under the Senior Secured Notes Indenture with respect to such Senior Secured Notes to the extent holders of the Trust Securities have accepted the Change of Control Offer with respect to the Trust Securities. Holders of the Trust Securities electing to have any Trust Securities purchased pursuant to a Change of Control Offer shall be required to surrender the Trust Securities to the Paying Agent on the Change of Control Offer Expiration Date. A Change of Control Offer Expiration Date with respect to the Trust Securities constitutes a Mandatory Exercise Event in respect of the Issuance Right following which Vistra Operations will be required to sell to the Trust Senior Secured Notes in a principal amount equal to the Change of Control Offer Issuance Amount; provided that Vistra Operations may elect to pay the Cash Settlement Amount with respect to the

-57-

Change of Control Offer Subject Issuance Amount in lieu of issuing such Senior Secured Notes. On the Change of Control Payment Date, Vistra Operations shall pay the Change of Control Payment to the Trust (which such payment may be made directly to the Trust to the extent no Senior Secured Note is held through the facilities of a depository, and all such Senior Secured Notes are held in the name of the Trust or otherwise, to the Senior Secured Notes Trustee for the benefit of the Senior Secured Noteholders), to repurchase a principal amount of Senior Secured Notes equal to (1) the Trust Securities Tendered Amount minus (2) the Change of Control Offer Subject Amount if Vistra Operations has paid the Cash Settlement Amount with respect thereto in lieu of issuance, at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to, but not including, the date of repurchase, in each case to the extent necessary to pay the Change of Control Payment with respect to the Trust Securities Tendered Amount. Senior Secured Notes repurchased or for which Vistra Operations has paid the Cash Settlement Amount in lieu of issuance pursuant to the foregoing cannot be re-issued.

(e) On the Change of Control Payment Date, to the extent lawful:

(i) the Trust will accept for payment all Trust Securities properly tendered pursuant to the Change of Control Offer;

(ii) Vistra Operations will deposit with the Paying Agent on behalf of the Trust as Senior Secured Noteholder (or with the Senior Secured Notes Trustee if any Senior Secured Notes are held in a depository for eventual payment to the Senior Secured Noteholders) an amount equal to the Change of Control Payment in respect of all Trust Securities properly tendered; and

(iii) Vistra Operations will deliver or cause to be delivered to the Trustee an officers’ certificate stating the aggregate initial purchase price of Trust Securities being re-purchased by the Trust.

(f) The Paying Agent (to the extent it has received such amounts) shall promptly distribute to each holder of Trust Securities properly tendered the Change of Control Payment for the Trust Securities. Vistra Operations shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(g) The foregoing provisions of this Section 5.17 that require the Trust to make a Change of Control Offer following a Change of Control Trigger Event shall be applicable whether or not any other provisions of this Declaration are applicable.

Article VI

GRANTOR TRUST

Section 6.1. Treatment as “Grantor” Trust. The offering of the Trust Securities is intended to be treated for United States federal income tax purposes as a financing wherein Vistra Intermediate, the regarded owner of Vistra Operations for United States federal income tax purposes, directly owns the assets held in the Trust and issues indebtedness directly to the Holders. To mitigate any uncertainty, however, in order to comply with certain information reporting requirements that could apply if Vistra Intermediate is treated as indirectly owning

-58-

such assets through the Trust, Vistra Operations and the Trust agree to take the position for all United States federal income tax purposes that the Trust is a “grantor” trust for United States federal income tax purposes and is not a partnership or an association subject to tax as a corporation, and that Vistra Intermediate is the sole “grantor” of the Trust and owner of the assets of the Trust for United States federal income tax purposes. The provisions of this Declaration shall be interpreted to further this intention of the parties.

Article VII

ACCOUNTING AND RECORDS

Section 7.1. Annual Tax Information.

(a) The Trustee shall cause the Trust to comply with information reporting and backup withholding requirements imposed on the Trust in connection with payments in respect of the Trust Securities. The Trustee shall undertake its information reporting and backup withholding obligations under this Section 7.1 consistent with the intent set forth in Section 6.1 absent a Change of Law or a change in administrative guidance or interpretation by the IRS or any state or local taxing authority. Pursuant to the engagement letter of the accounting firm of Cover & Rossiter referenced in Section 2.6(a)(xxv), Cover & Rossiter has agreed to notify the Trust and the Trustee if any future developments in the law or regulations would result in (i) the Trust having a classification other than a “grantor” trust which would require the Trust to prepare or file tax forms or returns that are different from those set forth in Section 7.1(b) or (ii) a requirement for “grantor” trusts to prepare or file tax forms or returns that are different from those set forth in Section 7.1(b). If the Trustee receives such notification from Cover & Rossiter or Vistra Operations, then promptly following the Trustee’s written request to Vistra Operations, Vistra Operations shall direct the Trustee in engaging Cover & Rossiter or another tax accounting firm to prepare such forms or returns. The expenses of such tax accounting firm shall be treated as Trust Expenses for the purposes of this Declaration and the Trust Expense Reimbursement Agreement. In addition, the authorizations and protections set forth in Section 2.6(a)(xxv) shall apply to the engagement of any such accounting firm.

(b) The Trustee shall cause the Trust to collect from, and deliver to, Vistra Operations and the Holders all applicable tax forms as required by law. The provisions of Section 7.1(b)(i)(A) and Section 7.1(b)(ii) shall apply unless otherwise required by a Change in Law or “determination” within the meaning of Section 1313(a) of the Code (as certified to in an Officer’s Certificate of the Depositor).

(i) In the case of Vistra Operations,

(A) the Trustee shall cause to be prepared and filed on a timely basis and at the expense of the Trust IRS Form 1041 with respect to the Trust. Consistent with the treatment of Vistra Intermediate as the sole “grantor” of the Trust and owner of the assets of the Trust for United States federal income tax purposes, such IRS Form 1041 shall contain only entity information with respect to the Trust and contain no information in respect of income received by the Trust. Such income shall instead be shown on a separate statement attached to such IRS Form 1041 as income received by Vistra Intermediate.

-59-

(B) the Trustee shall also cause to be duly prepared and filed with the appropriate taxing authority any other annual United States federal income tax information return and any other annual income tax returns required to be filed on behalf of the Trust with any state or local taxing authority. The Trustee shall also cause the Trust to furnish Vistra Operations with any additional forms or information as shall be reasonably requested by Vistra Operations to assist Vistra Operations or any Affiliate thereof in fulfilling its information reporting, backup withholding and income tax return obligations.

(ii) In the case of any Holder, unless an exemption from information reporting and backup withholding applies with respect to such Holder (an “exempt recipient”), the Trustee shall cause the Trust to timely deliver to such Holder the appropriate IRS Form 1099 or IRS Form 1042-S, reflecting that distributions from the Trust in respect of the Trust Securities are interest payments in respect of indebtedness of Vistra Intermediate paid by Vistra Intermediate to such Holder for United States federal income tax purposes. If payment is made to an exempt recipient, the Trustee shall cause the Trust to convey that, for United States federal income tax purposes, all payments made to such exempt recipient are payments of interest or principal. The Trust shall not report, for United States federal income tax purposes, any payment on the Trust Securities as a payment of put premium.

(c) Not later than the third Business Day following the last day of each calendar quarter (each, a “statement date”), the Trustee shall provide Vistra Operations a statement of the assets held in the Trust and any Designated Securities and/or Counterparty Securities outstanding as of the statement date, including (A) a description of such assets, (B) the market value of the Eligible Assets, and (C) the amount thereof, if any, that are Designated Securities and/or Counterparty Securities.

Section 7.2. Certain Accounting Matters.

(a) At all times during the existence of the Trust, the Trustee shall keep, or cause to be kept, full books of account, records and supporting documents, which shall reflect in reasonable detail each transaction of the Trust. The books of account shall be maintained on the accrual method of accounting, in accordance with generally accepted accounting principles, consistently applied.

(b) So long as any of the Trust Securities are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Trust shall, unless it becomes subject to and complies with Section 13 or 15(d) of the Exchange Act, provide or cause to be provided to each Holder of such restricted securities and to each prospective purchaser (as designated by such Holder) of such restricted securities, upon the request of such Holder or prospective purchaser, any information required to be provided by Rule 144A(d)(4) under the Securities Act.

Article VIII

DISSOLUTION AND TERMINATION OF THE TRUST

Section 8.1. Dissolution and Termination of the Trust.

(a) The Trust shall dissolve and liquidate in accordance with the Statutory Trust Act upon the date that is the earliest to occur of the following (the date of such earliest occurrence, the “Trust Dissolution Date”):

(i) May 17, 2028 (or on the following Business Day if such date is not a Business Day);

(b) The Trustee shall give prompt notice to the Holders and each Rating Agency of any event that may result in a Trust Dissolution Date pursuant to Section 8.1(a)(ii), (iii) or (iv), including the receipt of (i) any Issuance Notice in respect of the entire Available Amount if the Repurchase Right has been terminated, (ii) any Automatic Exercise Notice or (iii) any notice of redemption of Senior Secured Notes or any Issuance Notice in respect of which Vistra Operations has made a Cash Settlement Election that will, on the Vistra Operations Payment Date, reduce the Maximum P-Caps Outstanding Amount to zero.

(a) As soon as practicable after the Trust Dissolution Date, the Trustee shall liquidate the Eligible Assets and Substitute Deposits held by the Trust and seek to collect any amounts due under the Facility Agreement, the Trust Expense Reimbursement Agreement and any Senior Secured Notes held by the Trust; provided that, if the Trust is dissolved pursuant to Section 8.1(a)(ii), (iii) or (iv), the Trustee shall only liquidate any Eligible Assets or Substitute

-61-

Deposits if and to the extent the amounts collected from other sources are not sufficient to pay or set aside for payment for the Trustee’s Fee and all Trust Expenses due and payable and the Trustee shall deliver the remaining Eligible Assets to Vistra Operations in respect of such exercise of the Issuance Right prior to distributing any Trust Property to the Holders or other creditors of the Trust.

(b) (i) If the Trust is dissolved pursuant to Section 8.1(a)(ii) or (iii), after satisfying or setting aside for payment all amounts due as set forth in Section 8.2(c)(i) through (v), the Trustee shall (to the extent permitted by law) distribute the Senior Secured Notes pro rata to the Holders of the Outstanding Trust Securities as soon as practicable after the Trust Dissolution Date. If the Trust is unable to satisfy or set aside for payment all amounts due as set forth in Section 8.2(c)(i) through (v) from the amounts received under the Facility Agreement, Trust Expense Reimbursement Agreement, payments under the Senior Secured Notes and liquidation proceeds of any Eligible Assets that are not delivered to Vistra Operations, in accordance with the Statutory Trust Act, as soon as practicable after the Trust Dissolution Date, the Trustee shall liquidate its remaining Trust Property, including the Senior Secured Notes, in accordance with Section 8.2(d) to the extent necessary to cover all amounts due as set forth in Section 8.2(c)(i) through (v), and distribute any funds and any Senior Secured Notes it then holds in accordance with the priorities set forth in Section 8.2(c).

(ii) If the Trust is dissolved pursuant to Section 8.1(a)(i), the Trustee shall redeem all Outstanding Trust Securities on May 17, 2028 (or on the following Business Day if such date is not a Business Day) at a redemption price per Trust Security equal to the amount of principal and interest that would have been payable at maturity on $1,000 principal amount of Senior Secured Notes, subject to the priorities set forth in Section 8.2(c). If the Trust is dissolved pursuant to Section 8.1(a)(iv), the Trustee shall make the Distributions on the Vistra Operations Payment Date, as set forth in Section 5.10. All such Distributions made pursuant to this Section 8.2(b)(ii) shall be made only after the Trustee satisfies or sets aside for payment all amounts due as set forth in Section 8.2(c)(i) through (v). If the Trust is unable to satisfy or set aside for payment all amounts due as set forth in Section 8.2(c)(i) through (v) from the amounts received under the Facility Agreement and Trust Expense Reimbursement Agreement and payments under the Senior Secured Notes, in accordance with the Statutory Trust Act, as soon as practicable after the Trust Dissolution Date, the Trustee shall liquidate (A) any Eligible Assets and Substitute Deposits then held by the Trust to the extent necessary to satisfy or set aside for payment all amounts as set forth in Section 8.2(c)(i) through (v) and (B) thereafter any Senior Secured Notes then held by the Trust in accordance with Section 8.2(d), to the extent necessary to cover all amounts due as set forth in Section 8.2(c)(i) through (v), and distribute any funds it then holds in accordance with the priorities set forth in Section 8.2(c).

-62-

(c) To the fullest extent permitted by the Statutory Trust Act, on the Liquidation Distribution Date, the Trustee shall distribute the Trust Property in accordance with the following priorities:

(i) first, in satisfaction of the expenses of liquidation;

(ii) second, in payment of any Trustee’s Fee and any Trust Expenses then due and payable;

(iii) third, to Vistra Operations in satisfaction of any amounts then due and payable to Vistra Operations under the Facility Agreement;

(iv) fourth, in satisfaction of any other outstanding obligations of the Trust then due and payable, pro rata among those creditors in accordance with the aggregate unpaid amount due to each;

(v) fifth, to set aside any amounts required to reasonably provide for the payment of any known claims or contingent obligations pursuant to the Statutory Trust Act; and

(vi) sixth, to the Holders, pro rata with respect to each Trust Security, subject to the provisions set forth in Section 8.2(l).

The date on which the Trustee is required to make any distributions as set forth in Section 8.2(b) or Section 8.2(d) shall be the “Liquidation Distribution Date”.

(d) Notwithstanding Section 8.2(c), if the Trust Property includes Senior Secured Notes on the Trust Dissolution Date, and if the Trustee determines that any Senior Secured Notes must be liquidated in order to satisfy obligations of the Trust that rank prior to the Distributions to the Holders under Section 8.2(c)(vi), the Trustee shall not make any such Distribution pursuant to Section 8.2(c) until the date on which it has liquidated the Senior Secured Notes to the extent necessary to cover all amounts due as set forth in Section 8.2(c)(i) through (v). Pending the distribution of the Trust Property, the Trustee shall hold the Trust Property, other than any Senior Secured Notes held by the Trust, as provided in Section 2.6(c). To determine whether any Senior Secured Notes must be liquidated, the Trustee shall assume that it shall apply all Trust Property, other than the Senior Secured Notes, to all obligations and claims of the Trust ranking higher in order of priority than the rights of the Holders, and that the Senior Secured Notes shall be liquidated only to the extent such other Trust Property is insufficient. If the Trustee determines that it must liquidate any of the Senior Secured Notes, it shall liquidate such Senior Secured Notes in accordance with commercially reasonable market standards and in compliance with applicable securities laws. The Trustee shall use commercially reasonable efforts (including retaining third-party agents at the expense of the Trust) to liquidate the Senior Secured Notes as promptly as practicable, but in any event shall dispose of the Senior Secured Notes held by the Trust no later than the 90th day following the Trust Dissolution Date. The Trustee shall distribute the proceeds received from any liquidation of Senior Secured Notes pursuant to this Section 8.2(d) on the date on which the Trustee liquidates the required amount of Senior Secured Notes; provided that a purchaser for such Senior Secured Notes is available on such date.

-63-

(e) Notwithstanding Section 8.2(c), if the Trust Property includes any Return Obligation on the Trust Dissolution Date, the Trustee (acting at the written direction of Vistra Operations) shall use commercially reasonable efforts to liquidate any claim for the return of any Designated Securities and/or Counterparty Securities in accordance with commercially reasonable market standards.

(f) Upon the occurrence of an event referred to in Section 8.1(a)(v), the Trustee shall proceed to wind up the affairs of the Trust, liquidate the Trust Property, apply the proceeds of such liquidation in the following order of priority and liquidate:

(i) first, to the expenses of liquidation; and

(ii) second, to the payment of the debts and liabilities of the Trust, as required by applicable law, including any outstanding expenses, fees or indemnity obligations owing to the Trustee, and any Trust Expenses.

(g) For purposes of the application of this Section 8.2, all unrealized income, gain, loss and deduction of the Trust shall be treated as realized and recognized immediately before any such distributions.

(h) If the Trustee receives any funds or other Trust Property after the Liquidation Distribution Date, the Trustee shall distribute such funds or other Trust Property in accordance with the priorities set forth in Section 8.2(c), not later than the third Business Day following its receipt of such funds or other Trust Property.

(i) Unless a Majority of Holders determine otherwise, on the one-year anniversary of the Trust Dissolution Date, the Trustee shall (i) distribute any remaining Trust Property in kind or abandon such Trust Property and (ii) at the expense of the Depositor, file a certificate of cancellation of the Trust with the Secretary of State terminating the Trust.

(j) To the extent consistent with the priorities established by this Article VIII, the Trustee may make liquidation distributions after the Trust Dissolution Date but prior to the Liquidation Distribution Date only pursuant to an amendment or waiver of this Declaration made in accordance with Section 10.3.

(k) Once the assets of the Trust have been liquidated and distributed as set forth in this Section 8.2 and a certificate of cancellation has been filed by the Trustee as described above, the Trust shall be terminated in accordance with the Statutory Trust Act.

(l) If pro rata distribution of the Senior Secured Notes would result in any Holder being entitled to receive Senior Secured Notes with an aggregate principal amount that is not a multiple of $1,000, then the Trustee shall round the principal amount of the Senior Secured Notes deliverable to that Holder down to the nearest $1,000 and shall seek to liquidate any remaining Senior Secured Notes and distribute the proceeds of those remaining Senior Secured Notes to those Holders, pro rata in accordance with the principal amount of Senior Secured Notes such Holder would have otherwise been entitled to receive.

Any of the foregoing Persons may engage or be interested in any financial or other transaction with Vistra Operations or any Affiliate of Vistra Operations, or may act as depositary for, trustee or agent for, or act on any committee or body of holders of, securities or other obligations of Vistra Operations or its Affiliates.

Notes.
