TXU Energy Market Tracker+ is an innovative pricing plan that automatically lowers electricity prices if natural gas costs trend lower. Prices are being cut to respond to competitive conditions, and will be among the lowest-priced offers in the North Texas market. This is in comparison to plans that fully disclose pricing details, on an annualized basis assuming current natural gas prices.

In comparison to the former price-to-beat rate in effect on December 31, 2006, this new price is projected to save a typical TXU Energy Market Tracker+ customer who uses an average of 1500 kWh monthly 21 to 23 percent in off-peak months, which includes April and May, and 14 percent on an annualized basis at current natural gas levels.

With the introduction of this plan in early 2006, TXU Energy became the first company to offer an index-based energy plan that tracked natural gas prices according to a formula detailed in the Electricity Fact Label (EFL). Because of this formula, TXU Energy’s distinctive plan provides the benefit of transparency into how and when the price changes, unlike many competitor plans that allow price changes monthly at the provider’s sole discretion, without advanced notice, based on unspecified wholesale market conditions.

To protect customers against increased natural gas costs, the total price per kWh for TXU Energy Market Tracker+ is capped. This not only provides unique protection against natural gas costs that rise above the designated cap, but also provides the customer the ability to enjoy even greater savings if natural gas prices trend lower. While the previous TXU Energy Market Tracker+ plan was already lower than the former price-to-beat rate, the new price cut results in an additional 9 percent decrease on an annualized basis. A residential customer using an average of 1500 kWh monthly will pay an average annual price of 12.6 cents per kWh instead of the 13.9 cents that customer would have paid under the previous price of this plan at current gas levels.

The TXU Energy Market Tracker+ plan is available to all customers in the service area of TXU Electric Delivery (which has announced it will be changing its name to Oncor Electric Delivery later this month). Current TXU Energy Market Tracker+ customers are automatically receiving the new lower prices effective today.

This voluntarily expedited initial filing means the PUC will have direct authority to hold the investors legally accountable to their commitments once the transaction closes.

TEF made its filing today with the PUC in anticipation of its voluntarily expedited 14.101 filing, which allows the PUC to review the buyout transaction. That filing will be made no later than April 25, 2007.

TEF is legally committing to hold a majority of its ownership stake, in the current regulatory system, for a minimum of five years, and committing that TXU Electric Delivery will not incur, guaranty or pledge assets in respect of any borrowing related to financing the merger transaction. TEF is also committing to establish a separate board for each of TXU’s three operating companies and to make substantial investments in new energy efficiency programs. More details on those commitments are listed below.

The PUC filing includes the following commitments by TEF:

- On or before closing of the transaction, the name of TXU Electric Delivery will be changed to Oncor Electric Delivery Company. Oncor’s logo will be separate and distinct from the logos of the parent, TXU Corp.; the retail electric provider, TXU Energy; and the power generation company, Luminant Energy.

- At closing and thereafter, Oncor will have a separate board of directors that will not include any members from the boards of directors of TXU Energy or Luminant.

- Within a reasonable transition period after closing of the merger transaction, not to exceed six months, Oncor’s headquarters will be located in a separate building from the headquarters and operations of TXU Energy and Luminant.

- Oncor will not incur, guaranty or pledge assets in respect of any borrowing related to financing the merger transaction. Oncor’s financial integrity will be protected from the separate operations of TXU Energy and Luminant.

- TEF will limit Oncor’s debt so that its debt-to-equity ratio is at or below the assumed debt-to-equity ratio established from time to time by the Commission for ratemaking purposes, which is currently set at 60:40. For ratemaking purposes, in its next rate case Oncor will support a cost of debt that does not exceed Oncor’s actual cost of debt immediately prior to the announcement of the proposed merger transaction.

- Following the closing of the proposed transaction, TEF intends for Oncor to continue to make capital expenditures at or above current levels. Total capital spending will depend in part on economic growth, permitting and siting. However, TEF commits that over the five years following the year in which closing of the proposed transaction occurs, Oncor will make capital expenditures in connection with its transmission and distribution business in an aggregate amount of more than $3.0 billion.

- Over the five years following the year in which closing occurs, subsidiaries of TXU Corp. will expend an aggregate of at least $200 million on demand-side management/energy efficiency programs over the amount included by the Commission in Oncor’s rates. This commitment will approximately double Electric Delivery’s current level of spending on DSM. Oncor will not seek to recover in rates any of the $200 million in incremental DSM expenditures.

- Oncor will support the inclusion of negotiated commitments with appropriate stakeholders regarding reliability, customer service and employee safety in any Final Order regarding the merger transaction issued pursuant to PURA Section 14.101.

- Oncor will file a general rate case at the Commission before July 1, 2008, consistent with the utility’s currently effective settlement agreement with certain municipalities.

- TEF will hold a majority of its ownership interest in Oncor, in the current regulatory system, for a period of more than five years after the closing date of its proposed merger transaction.

A copy of the PUC filing is available at http://www.texasenergyfuture.com/

Under the terms of the merger agreement, shareholders will be paid $69.25 per share at closing. The transaction is subject to receipt of shareholder approval and required regulatory approvals, as well as satisfaction of other customary closing conditions. There is no financing condition to the transaction.

Under the merger agreement, TXU has the right to solicit other proposals through April 16, 2007. The TXU Board, acting through the Strategic Transactions Committee of the Board, with the assistance of Lazard, has solicited interest from over 70 potential purchasers, including US utility companies, non-US utility companies, other energy companies and financial sponsors and infrastructure investors. TXU has entered into confidentiality agreements with nine of these entities and provided them confidential information regarding TXU and its subsidiaries.

Despite these efforts, through April 1, 2007, none of the parties contacted has submitted a formal proposal, and there is no indication that any of the parties is preparing a proposal that will be superior from either a price or transaction certainty perspective.

While TXU remains open to receiving competing proposals and will continue to work with its financial advisor through the go shop period to determine if there are possible competing proposals that could be superior to the existing proposal, Lazard has advised the Strategic Transactions Committee that it does not believe any superior proposal will be submitted as a result of its go shop efforts.

U. S. Steel expects that the acquisition of Lone Star will strengthen its position as a premier producer of tubular products for the energy sector and will create North America’s largest tubular producer. The transaction will broaden U. S. Steel’s energy product offerings by joining U. S. Steel’s predominantly seamless tubular business with Lone Star’s complementary welded tubular business, coupling manufacturing and tubular processing services. Following the transaction, U. S. Steel will have annual North American tubular manufacturing capability of approximately 2.8 million tons.

U. S. Steel expects that the transaction will be accretive to its 2007 earnings per share before considering expected synergies and excluding the accounting effects of the sale of acquired inventory and other customary purchase accounting adjustments. U. S. Steel projects that the combination with Lone Star’s operations will generate annual pre-tax operating synergies in excess of $100 million by the end of 2008.

Under the terms of the definitive agreement, U. S. Steel will acquire all of the outstanding shares of Lone Star for $67.50 per share in cash – an aggregate value of approximately $2.1 billion. The price per share represents a premium of approximately 39 percent to Lone Star’s closing share price of $48.45 on March 28, 2007, and a premium of approximately 43 percent to its 90- day average trading price.

U. S. Steel will pay for the acquisition through a combination of cash on hand and financing obtained under its existing receivables purchase program and three new fully committed bank credit facilities provided by JPMorgan.

The transaction is subject to the approval of Lone Star’s shareholders and other customary closing conditions, including regulatory approvals, and is expected to close in the second or third quarter of 2007.

J.P. Morgan Securities Inc. and Morgan, Lewis & Bockius LLP acted as financial and legal advisers, respectively, to U. S. Steel. Goldman, Sachs & Co. and Weil, Gotshal & Manges LLP acted as financial and legal advisers, respectively, to Lone Star.
