*** Ref: _____________

Dear Sirs:

The purpose of this letter agreement (this “Confirmation”) is to confirm the terms and conditions of the transaction entered into between *** (“Party A”) and TXU Generation Development Company LLC, a Delaware limited liability company (“Party B”) on the Trade Date specified below (this “Transaction”).

The definitions and provisions contained in the 2000 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. (“ISDA”), as supplemented from time to time, (collectively the “2000 ISDA Definitions”) are incorporated into this Confirmation. Additionally, the 2005 Commodity Derivatives Definitions, as supplemented or modified from time to time (collectively, the “Commodity Definitions”) published by ISDA are hereby incorporated into this Confirmation by reference with respect to any “Transactions” (as defined by the Commodity Definitions) in commodities, except as otherwise specifically provided in this Confirmation. In the event of any inconsistency between the 2000 Definitions and the Commodity Definitions with respect to such Transactions, the Commodity Definitions will prevail.

This Confirmation evidences a complete and binding agreement between Party A and Party B as to the terms of the Transaction to which this Confirmation relates. The Parties to this Confirmation shall in good faith attempt to negotiate and execute a 1992 ISDA Master Agreement (Multicurrency-Cross Border) (the “ISDA Form” or, when executed, the “Agreement”) with such modifications as Party A and Party B will in good faith agree. Upon execution of the Agreement, this Confirmation will supplement, form a part of, and be subject to that Agreement. Until Party A and Party B execute and deliver the Agreement, if any, this Confirmation, together with all other documents referring to the ISDA Form (each a “Confirmation”) confirming transactions (each a “Transaction”) entered into between Party A and Party B (notwithstanding anything to the contrary in a Confirmation), shall supplement, form a part of, and be subject to an agreement (which shall survive the termination of this Transaction) in the form of the ISDA Form as if Party A and Party B had executed an agreement in such form effective as of the Trade Date of the first Transaction between Party A and Party B (but without any Schedule except for (i) the election of Loss and Second Method for the purposes of payments on early termination, (ii) New York law as the governing law, (iii) US Dollars (“USD”) as the Termination Currency, (iv) specifying that Section 2(c)(ii) of the ISDA Form will not apply, (v) Section 5(a)(vi) of the ISDA Form shall be amended by: (A) deleting the phrase “, or becoming capable at such time of being declared,” therefrom, (B) the Threshold Amount with respect to Party B shall be $50,000,000 up to and including December 31, 2007 and $100,000,000 on and after January 1, 2008, and (C) deleting clause (2) thereof with respect to Party B, and (vi) Party A is the Calculation Agent unless an Event of Default or a Potential Event of Default where Party A is the Defaulting Party shall occur, in which case Party B shall be the Calculation Agent).

This Transaction and any future Transactions between the parties are entered into on the understanding that this Confirmation and any future Confirmations form a single agreement between the parties, and the parties would not otherwise enter into any Transaction(s).

This Confirmation supersedes any prior oral or written agreement between the Parties regarding the subject matter hereof. This Confirmation, together with the ISDA Form, shall constitute the entire agreement between the Parties with respect to this Transaction.

In the event that notional amount of MMBtus hedged under this Transaction, together with any other Transactions under the Agreement or any other Back to Back Documentation and any hedge documentation with third-party hedge providers (collectively, for any such year, the “Total Notional Hedge”) results in Party B having outstanding notional amounts in respect in any Hedge Year in excess of the Permitted Hedge Capacity as calculated by Party B hereunder for such year, Party A and Party B agree that, within five (5) Business Days after Party B provides the Hedge Capacity Notice (the “Hedge Transfer Date”), Party B shall novate or otherwise transfer to a Permitted Transferee pursuant to a Novation Agreement Party B’s rights and obligations under a pro rata portion of the Total Notional Hedge in excess of the Permitted Hedge Capacity under this Transaction, Transactions under the Agreement or under any other Back to Back Documentation (in each case as may be outstanding with Party A), which results in Party B retaining a basket of hedge transactions that keeps the average hedged price for such Hedge Year approximately the same as it was prior to such novation or transfer. On or immediately prior to the Hedge Transfer Date and as a condition precedent to the effectiveness of the Novation Agreement, each of Party B and the Permitted Transferee shall represent to Party A that it is not subject to an event or circumstance set forth Section 5(a)(vii) of the ISDA Form (or the Agreement if then executed). Provided that Party B has complied in full with its obligations under this Section 2(f)(i), Party A agrees to: (x) enter into such novation or other transfer to a Permitted Transferee without requiring any termination payment or mark-to-market payment in connection therewith (i.e., the hedge will be transferred at the original contract price with any embedded gain or loss not being realized at transfer); (y) pay to the Permitted Transferee a fee*** transferred as provided in this paragraph upon the novation or transfer of the relevant hedge to the Permitted Transferee; and (z) execute a Novation Agreement with Party B and the Permitted Transferee to give effect to such novation or transfer. If the Big Brown Collateral or Alternative Physical Collateral that serves as the collateral for the Permitted Transferee had previously been released upon the occurrence of the Five Plant Permit Date, then the liens on such collateral will be reconstituted thereon through the delivery of the documentation listed in Section 2(c)(i)(A) or 2(c)(i)(B)(1), as applicable. Further, if the Big Brown Collateral or Alternative Physical Collateral serves as the collateral for the Permitted Transferee, then Party A’s interest in such collateral shall be limited solely to its Modified Percentage of the value of such collateral. For the avoidance of doubt, after giving effect to this clause (f)(i), all portions of this Transaction, other Transactions under the Agreement and under Back to Back Documentation that (AA) are not subject to transfer or novation pursuant to this Section 2(f)(i) shall be secured solely by the DevCo Collateral and shall have no claim against the Big Brown Collateral or the Alternative Physical Collateral and (BB) are subject to transfer or novation pursuant to this Section 2(f)(i) shall be secured solely by the Big Brown Collateral or the Alternative Physical Collateral, as applicable, and shall have no claim against the DevCo Collateral.

(ii)

Sale of Assets. In the event that DevCo shall sell or transfer any DevCo Facility (including, without limitation, through the sale of a Subsidiary Guarantor), Party B shall calculate the “Allowed Hedge Capacity”, which shall equal 51,000,000 MMBtus of natural gas hedge transactions per 1,000 MW of gross capacity for each DevCo Facility still owned by DevCo or one of its subsidiaries (excluding the DevCo Facility to be sold) that is scheduled to be commercially available in such calendar year (provided that the size of the maximum allowed hedge position will be prorated to reflect the monthly production schedule in each such Hedge Year), and provide written notice of such Allowed Hedge Capacity to Party A, for each Hedge Year that has not theretofore commenced (the “Transfer Hedge Capacity Notice”). Party B shall notify Party A in the event that the outstanding notional amounts if any in respect of any Hedge Year would be in excess of the Allowed Hedged Capacity after such sale

or transfer. Party A and Party B agree that at the closing of such sale or transfer, Party B shall, at its option: (A) terminate all or a portion of this Transaction, Transactions under the Agreement or under any other Back to Back Documentation (with the appropriate Party making the termination payment pursuant to Section 6(e) of the ISDA Form or the Agreement (as applicable)); or (B) novate or otherwise transfer to a Permitted Purchaser pursuant to a Novation Agreement Party B’s rights and obligations under all or a portion of this Transaction, Transactions under the Agreement or under any other Back to Back Documentation (in each case as may be outstanding with Party A), such that the outstanding notional amounts in respect of each Hedge Year are no longer in excess of the Allowed Hedged Capacity; provided, however, that such novation or transfer shall be subject to providing collateral to Party A of reasonably equivalent value (and in a dispute in respect thereof, such value will be determined by an experienced independent appraiser). In each case, such termination, transfer or novation must result in Party B retaining a basket of hedge transactions that keeps the average hedged price for each Hedge Year approximately the same as it was prior to such termination, transfer or novation. On or immediately prior to the date of a novation and as a condition precedent to the effectiveness of the Novation Agreement, each of Party B and the Permitted Purchaser shall represent to Party A that it is not subject to an event or circumstance set forth Section 5(a)(vii) of the ISDA Form (or the Agreement if then executed). Provided that Party B has complied in full with its obligations under clause (B) of this Section 2(f)(ii), Party A agrees to (x) enter into such novation or other transfer to a Permitted Purchaser without requiring any termination payment or mark-to-market payment in connection therewith (i.e., the hedge will be transferred at the original contract price with any embedded gain or loss not being realized at transfer); and (y) execute a Novation Agreement with Party B and the Permitted Purchaser to give effect to such novation or transfer.

(iii)

Pre-Completion Shortfall. In the event that any settlement date shall occur under this Transaction, other Transactions under the Agreement or any other Back to Back Documentation *** (the “Draw Window”) and Party B cannot make payment of any amount due to Party A in respect of this Transaction, other Transactions under the Agreement or any other Back to Back Documentation on such settlement date due to insufficient funding caused by construction delays beyond those mitigated by the novations in Section 2(f)(i) (a “Pre-Completion Shortfall”), Party B shall provide written notice to Party A of such Pre-Completion Shortfall (a “Pre-Completion Shortfall Notice”). Upon receipt of a Pre-Completion Shortfall Notice from Party B, Party A shall cause its Affiliate to advance funds to Party B in amounts necessary to pay such Pre-Completion Shortfall in accordance with the terms of the credit facility to be underwritten by an Affiliate of Party A and as further defined in Schedule 2 (“Credit Facility Terms” ). Provided that Party B makes any settlement payments estimated by Party A to be associated with such Pre-Completion Shortfall from such facility, Party A agrees not to assert or otherwise exercise any rights in respect of a Potential Event of Default, Event of Default or other “default” howsoever described in the related documentation arising directly in respect of such Pre-Completion Shortfall.

(iv)

DevCo Facility Status Updates and Viability. Party B shall provide Party A with the same regular status updates concerning the construction of the DevCo Facilities that are provided to the holders of indebtedness under the First Lien Credit Facilities. If, after December 31, 2007, a “Permitted Abandonment” or “Permitted Removal” as such terms are defined in the Senior Credit Facilities shall occur with respect to a DevCo Facility, Party B shall calculate the “Remaining Hedge Capacity”, which shall equal 51,000,000 MMBtus of natural gas hedge transactions per 1,000 MW of gross capacity for each DevCo Facility (excluding the DevCo Facilities subject of such Permitted Removal or Permitted Abandonment) that is scheduled to be commercially available in each Hedge Year (provided that the size of the maximum allowed hedge position will be prorated to reflect the monthly production schedule in each such Hedge Year), and provide written notice of such Remaining Hedge Capacity to Party A. In the event that the Total Notional Hedge then outstanding in any Hedge Year is in excess of the Remaining Hedge Capacity as calculated by Party B hereunder for such Hedge Year, Party B shall, at its option: (1) terminate (with the appropriate Party making the termination payment pursuant to Section 6(e) of the ISDA Form (or the Agreement, as applicable)); or (2) novate or otherwise transfer to a Permitted Transferee, in each case the pro rata portion of this Transaction, Transactions under the Agreement or under any other Back to Back Documentation associated with such delayed DevCo Facility under the same terms and conditions as set forth in Section 2(f)(i).

(C)

the NYMEX Contracts and OTC XX Xxxxxx to be transferred under this Section 9 shall be assigned, novated or otherwise transferred to Party A at the original contract price being applicable to the underlying NYMEX Contract or OTC NG Hedge (i.e., the hedge will be transferred at the original contract price with any embedded gain or loss not being realized at transfer), as applicable; provided, however, ***

All transactions subject to the Back to Back Documentation that occur as a result of novated OTC XX Xxxxxx that are not exchange-cleared at the time of novation will have a notional value equal to the notional value of such novated transactions.

(E)

the Back to Back Documentation shall provide that the sole collateral for Party B’s obligations in respect of the Back to Back Documentation will be as provided in Section 2 hereof, with its Collateral Percentage being at all times equal to the quotient of: (a) the aggregate notional amount, in MMBtus, of all Transactions with Party A under the Agreement and, without duplication, other Back to Back Documentation with Party A, divided by (b) the Full Hedge Amount;

(F)

within five (5) Business Days of the execution of Back to Back Documentation with respect to each transferred NYMEX Contract and OTC NG Hedge, Party B shall pay a fee ***; and

(G)

no more than *** of NYMEX Contracts shall be the subject of this Section 9.

4. this Guarantee is its legal, valid and binding obligation enforceable against it in accordance with its terms except as enforcement hereof may be limited by applicable bankruptcy, insolvency, reorganization or other similar laws affecting the enforcement of creditors' rights or by general equity principles.

This Guarantee may be terminated upon 15 days prior written notice to that effect actually received by Counterparty. Such termination shall not, however, affect or reduce *** obligation hereunder for any liability of *** incurred prior to such termination.

*** hereby agrees that it shall pay all reasonable costs, fees and expenses (including reasonable attorneys' fees and disbursements) incurred by Counterparty in successfully enforcing *** obligations under this Guarantee.
