Excluding this non-cash change, the Company=s adjusted earnings were $456 million, or $0.92 per share ($0.91 diluted), compared to first quarter 2007 adjusted earnings of $406 million, or $0.89 per share ($0.87 diluted).¹

XTO Energy Announces 1Q Earnings and Record Production

“Our exceptional results in the first quarter provide a strong start to what we believe will be another record year for XTO,” stated Bob R. Simpson, Chairman and Chief Executive Officer. “With the ongoing success of our capital programs, we are increasing the production growth target to 23% for the year, up from 20%. Given the unique opportunities in the acquisition market, we are also securing both producing properties and bolt-on leasehold to expand our future growth platforms, from East Texas to our multiple shale basins. As shareholders, we are imposing our commitment and discipline to creating long term value.”

Keith A. Hutton, President, further comments. AOur operational teams delivered another record quarter with production volumes up 32% year over year, and 3% sequentially. In East Texas, the daily production from the Freestone Trend continued to move upwards, averaging 677 MMcfe for the period. In the Barnett Shale, current gross production has now reached 620 MMcfe per day. Our drilling in the Woodford and Fayetteville shales yielded several new wells with daily production rates averaging 3 MMcfe and 2 MMcfe, respectively. From our efforts in both west and south Texas, oil production increased by 6% over the last quarter, as significant wells came online. Overall, the Company is now operating 84 drilling rigs. Looking ahead in 2008, we are increasing our development budget from $2.6 to $3 billion to accommodate XTO’s expanding growth opportunities.@

The average gas price for the first quarter increased 4% to $7.70 per thousand cubic feet (Mcf) from $7.37 per Mcf in first quarter 2007. The first quarter average oil price was $80.74 per barrel, a 21% increase from last year=s first quarter average price of $66.62. Natural gas liquids prices averaged $52.98 per barrel for the quarter, 47% higher than the 2007 quarter average price of $35.97.

(a) Includes geological and geophysical costs, as well as dry hole costs of $1 million in the three-month 2008 period and $2 million in the three-month 2007 period.

(b) Includes non-cash incentive award compensation of $41 million in the three-month 2008 period and $17 million in the three-month 2007 period.

(c) The derivative fair value (gain) loss comprises the change in fair value of the following derivative financial instruments not providing effective hedges (in millions):

	Three Months Ended March 31,

Other non-hedge derivatives	$	(29	)	$	2
Ineffective portion of hedge derivatives		13			(14	)
Total derivative fair value (gain) loss	$	(16	)	$	(12	)

(d) Net of capitalized interest of $7 million in the three-month 2008 period and $6 million in the three-month 2007 period.

(e) The current income tax provision exceeds cash tax expense by the benefit realized upon exercise of stock options not expensed in the financial statements. This benefit, which is recorded in additional paid-in capital, was $62 million for the three-month 2008 period and $13 million for the three-month 2007 period.

(f) All weighted average common share and earnings per common share amounts have been adjusted for the five-for-four stock split effected December 13, 2007.

(g) Average sales prices include realized gains and losses upon cash settlement of hedge derivatives.

Realized gains and losses on non-hedge derivatives and on the ineffective portion of hedge derivatives are recorded as a component of derivative fair value (gain) loss (see (c) above). These non-hedge and ineffective derivative gains and losses are primarily related to the timing of entering basis swap agreements and designating them as hedges associated with NYMEX swaps. Had realized non-hedge and ineffective gains and losses, attributable to first quarter production, been recorded as gas, natural gas liquids and oil revenue, the average gas, natural gas liquids and oil prices would have been:

	Three Months Ended March 31,
	2008		2007
Gas (per Mcf)	$	7.72	$	7.77
Natural gas liquids (per Bbl)		52.96		35.97
Oil (per Bbl)		80.73		67.12

(h) These adjustments are made to current assets, current liabilities and stockholders= equity because these items are recorded based on estimated derivative fair values and resulting unrealized gains and losses. Realized gains and losses will be based on commodity prices when related future production occurs. Net assets and equity to be recorded when future production occurs are not included in the balance sheet.

Non-GAAP Financial Measures

Adjusted Earnings

Adjusted earnings, a non-GAAP financial measure, excludes certain items that management believes affect the comparability of operating results. The Company discloses adjusted earnings as a useful adjunct to GAAP net income because:

B Management uses adjusted earnings to evaluate the Company=s operational trends and performance relative to other oil and gas producing companies.

B Adjusted earnings are more comparable to earnings estimates provided by securities analysts.

B Items excluded generally are items whose timing or amount cannot be reasonably estimated. Accordingly, any guidance provided by the Company generally excludes information regarding these types of items.

The following reconciles GAAP net income to adjusted earnings:

(in millions, except per share amounts)	Three Months Ended March 31,
(Unaudited)	2008			2007
Net income	$	465		$	383
Adjustments, net of tax:
Non-cash derivative fair value (gain) loss		(9	)		23
Adjusted earnings	$	456		$	406
Adjusted earnings per common share:
Basic	$	0.92		$	0.89
Diluted	$	0.91		$	0.87

Operating Cash Flow

Operating cash flow, a non-GAAP financial measure, is defined as cash provided by operating activities before changes in operating assets and liabilities and exploration expense. Because changes in operating assets and liabilities and exploration expense are excluded, this cash flow statistic is different from cash provided by operating activities, as disclosed under GAAP. Management believes operating cash flow is a better liquidity indicator for oil and gas producers because of the adjustments made to cash provided by operating activities, explained as follows:

B Adjustment for changes in operating assets and liabilities eliminates fluctuations primarily related to the timing of cash receipts and disbursements, which can vary from period-to-period because of conditions the Company cannot control (for example, the day of the week on which the last day of the period falls), and results in attributing cash flow to operations of the period that provided the cash flow.

B Adjustment for exploration expense is to provide an amount comparable to operating cash flow for full cost companies and to eliminate the effect of a discretionary expenditure that is part of the Company=s capital budget.

Management uses operating cash flow not only for measuring the Company=s cash flow and liquidity, but also in evaluating the Company against other oil and gas producing companies and valuing potential producing property acquisitions.

The following reconciles cash provided by operating activities, the GAAP cash flow measure, to operating cash flow:

(in millions)	Three Months Ended March 31,
(Unaudited)	2008		2007
Cash Provided by Operating Activities	$	957	$	851
Changes in operating assets and liabilities		83		(58	)
Exploration expense, excluding dry hole expense		17		2
Operating Cash Flow	$	1,057	$	795
