HALLIBURTON ANNOUNCES PRELIMINARY RESULTS OF KBR EXCHANGE OFFER
AND PRELIMINARY PRORATION FACTOR

HOUSTON, TX — Halliburton Company (NYSE: HAL) today announced that, based on preliminary results, the offer to its stockholders to exchange shares of Halliburton common stock for shares of KBR, Inc. (NYSE: KBR) common stock held by Halliburton was oversubscribed. The exchange offer expired at 12:00 midnight, New York City time, on April 2, 2007. Under the terms of the exchange offer, 1.5905 shares of KBR common stock will be exchanged for each share of Halliburton common stock accepted in the exchange offer. Stockholders who tendered their shares by delivering a notice of guaranteed delivery on April 2, 2007 before expiration of the exchange offer must deliver the related shares and required documents to the exchange agent by no later than 5:00 p.m., New York City time, on Thursday, April 5, 2007.

According to the exchange agent, Mellon Investor Services LLC, a total of 210,740,976 shares of Halliburton common stock were tendered for exchange and not withdrawn prior to the expiration of the exchange offer, including 104,047,893 shares tendered by guaranteed delivery procedures. Because more than 85,273,184 shares of Halliburton common stock have been tendered, the exchange offer is oversubscribed and Halliburton will only be able to accept a portion of the number of shares of Halliburton common stock that were validly tendered, on a pro rata basis in proportion to the number of shares tendered. Stockholders who owned less than 100 shares of Halliburton common stock, or an “odd-lot,” who have validly tendered all of their shares will not be subject to proration if they so elected in accordance with the terms of the exchange offer.

Based on the total number of shares of Halliburton common stock reported to be tendered prior to the expiration of the exchange offer, it is estimated that approximately 40% of the tendered Halliburton common stock will be accepted for exchange (assuming all shares tendered by guaranteed delivery procedures are delivered under the terms of the exchange offer). This preliminary proration factor is subject to change based on the number of tendered shares which satisfy the guaranteed delivery procedures by the expiration of the guaranteed delivery period. Halliburton expects to announce the final proration factor and its acceptance of validly tendered shares of Halliburton common stock promptly following the expiration of the guaranteed delivery period and confirmation that the conditions to the offering have been satisfied or waived. Shares of Halliburton common stock tendered but not accepted for exchange will be credited to the tendering holder’s account in book-entry form promptly after the final proration factor is announced.

Shares of KBR common stock to be distributed pursuant to the terms of the exchange offer will be credited in book-entry form to accounts of the tendering holders by the exchange agent promptly after the final proration factor is announced. Under the terms of the exchange offer, no fractional shares of KBR common stock will be distributed. Instead, fractional shares will be aggregated and sold, and the net cash proceeds of such sale will be distributed promptly to tendering stockholders in accordance with their fractional interests in the shares sold.

Credit Suisse Securities (USA) LLC and Goldman, Sachs & Co. served as the dealer managers for the exchange offer.
