AMENDMENT TO STIPULATION

REGARDING SECTION I, PARAGRAPH 35 AND EXHIBIT B

On October 24,
2007, the following parties filed a settlement of all issues in this docket (the Stipulation): Oncor Electric Delivery Company (Oncor), Texas Energy Future Holdings Limited Partnership (TEF), the Staff of the
Public Utility Commission of Texas (Staff), the Office of Public Utility Counsel (OPC), Texas Industrial Energy Consumers (TIEC), the Steering Committee of Cities Served by Oncor Electric Delivery Company
(Cities), the State of Texas (State), the Texas State Association of Electrical Workers (IBEW), Texas Ratepayers Organization to Save Energy (Texas ROSE) and Texas Legal Services Center
(TLSC) (hereinafter collectively referred to as Signatories.). The Signatories submitted the Stipulation to the Commission as representing a just and reasonable disposition of the issues related to this docket consistent with
the public interest, and requested approval of this Stipulation and entry of findings of fact and conclusions of law consistent with that approval.

Following additional discussions, the Signatories have agreed to execute this Amendment to the Stipulation regarding Section I, Paragraph 35 and Exhibit B (this Amendment), and agree as follows:



|I. | AMENDMENTS TO THE STIPULATION
|-- | -----------------------------

A. Revised
Section I, Paragraph 35.

Existing Section I, Paragraph 35 in the Stipulation is hereby replaced and amended to read as follows:



| | (35) | Oncor will provide a one-time credit of $72 million to REPs to be directly paid or credited to their retail customers. The one-time credit shall be allocated and
provided as reflected on Exhibit B to this Stipulation. The credit shall be provided over the first full Oncor billing month that starts at least 45 days after the Commission dismisses P.U.C. Docket No. 34040. Oncor will notify all Retail
Electric Providers (REPs) in its service area
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | that the credit will be available only to those REPs that within 15 days of receiving the notice agree in writing to: (1) directly pay or credit the
amount in full to retail customers by ESI ID within 45 days of receipt the amount received through the Texas SET 810_02 transaction from Oncor, and (2) file an affidavit with the Commission within 60 days of the last day of the billing month in
which the credits were provided stating that the credits which it received in this proceeding through the Texas SET 810_02 transactions were directly paid or credited to its retail customers. Oncor shall notify participating REPs of the first and
last dates of the full Oncor billing month it has used in providing credits to the participating REPs. Oncor will file an affidavit with the Commission providing a list of the participating REPs within 15 days after the deadline for REPs to indicate
their agreement to participate. To the extent that certain REPs do not participate in the credit, Oncor will reallocate in the same proportions the remaining portion of the $72 million credit to the REPs participating in the credit so that the full
$72 million credit is received by participating REPs and directly paid or credited to retail customers. Credit amounts that are unclaimed by non-industrial customers after the initial REP allocation and reallocation will be allocated on a pro rata
basis by Oncor to the bill payment assistance program of each participating REP that serves residential customers. Within 30 days after providing the credit, Oncor will file an affidavit with the Commission stating that it has provided the $72
million credit and listing the total amount credited by customer class, and the remaining amounts paid to REPs for bill payment assistance programs. This $72 million one-time credit to retail customers shall count as a reduction to net income in the
calculation of net income for dividend payment purposes described in paragraph (23). TEF will ensure that TXU Energy Retail passes the entire credit that it receives directly through to its retail customers. The parties agree that the one-time
credit will not be recovered by Oncor in any future proceedings, and further agree that they will not argue that the credit is any precedent or support for a rate reduction in the 2008 rate case or any future rate proceeding. The Signatories will
request the Commission to dismiss P.U.C. Docket No. 34040, Commission Staffs Petition for Review of the Rates of TXU Electric Delivery Company, and Oncor will agree to file a system-wide rate case no later than July 1, 2008
based on a test-year ended December 31, 2007.

Credit Methodology

General

Oncor will calculate a credit amount per ESI ID in accordance with the methodology set forth in this Exhibit
B. Oncor will use the standard Texas SET 810_02 transaction with specific transaction charge code (SER 105) in order to provide the allocated share of $72 million credit to the participating REPs by ESI ID. The credit will be calculated on an ESI ID
basis for each end-use retail customer of a participating REP as of the last billing day of Oncors December 2007 billing cycle. Each per ESI ID credit amount shall be truncated to the cent. The credit amount for each ESI ID will be sent to
that end-use retail customers REP as of the date of the credit, by ESI ID.

Residential Service ($32,983,398.59)

The Residential Rate Class credit will be based on a fixed $ amount per Residential ESI ID that will be calculated as follows: $32,983,398.59/ Total Number of
participating REP Residential ESI IDs determined as of the last billing day of Oncors December 2007 billing cycle.

Secondary Service Less Than or
Equal to 10 kW ($790,769.48)

Same process used for Residential Service.



13



---

Secondary Service Greater Than 10 kW ($26,427,614.56)

The Secondary Service Greater Than 10 kW customer credit will be determined based on each participating REPs customers (on a per ESI ID basis) 2007 annual kWh
consumption as a percentage of the total 2007 participating REPs annual Secondary Service Greater Than 10 kW class kWh.

Each individual ESI
IDs percentage as calculated above will be multiplied by the total class credit of $26,427,614.56.

Primary Service Less Than or Equal to 10
kW ($11,163.78)

Same process used for Residential Service.

Primary Service Greater Than 10 kW ($5,279,308.63)

Same process used for Secondary Service Greater Than 10 kW.

Transmission Service ($5,401,089.92)

Same process used for Secondary
Service Greater Than 10 kW.

Lighting Service ($1,106,655.05)

The Lighting Service credit of $1,106,655.05 will be allocated to the various types of lights based on the light types percentage of the total revenue for the 2006 calendar year.

For Street Light Schedules A, B, C, D, and Outdoor Lights, the credit will be based on a fixed $ amount per light
type calculated by dividing the allocated amount for each light type by each participating REPs number of lights in that type as of last billing day of Oncors December 2007 billing cycle.

For metered streetlight service, the credit will be calculated for each metered premise based on each participating REPs metered premises 2007 annual revenue
as a percentage of the total 2007 revenue for metered Street Light Service.
