trust. Predecessors of XTO Energy distributed units to their owners in February 1991 and November 1992, and in February 1992, sold units in the trust&#146;s initial public offering. Units are listed and traded on the New York Stock Exchange under
the symbol &#147;CRT.&#148; During 1996 and 1997, XTO Energy purchased 1,360,000 units on the open market. On September&nbsp;18, 2003, XTO Energy distributed all of the 1,360,000 trust units it owned as a dividend to its common stockholders. XTO
Energy currently is not a unitholder of the trust. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">Under the
terms of each of the five conveyances, the trust receives net profits income from the net profits interests generally on the last business day of each month. Net profits income is determined by XTO Energy by multiplying the net profit percentage
(90% or 75%) times net proceeds from the underlying properties for each conveyance during the previous month. Net proceeds are the gross proceeds received from the sale of production, less &#147;production costs&#148;, as defined in the conveyances.
For the 90% net profits interests and the 75% net profits interests, production costs generally include applicable property taxes, transportation, marketing and other charges. For the 75% net profits interests only, production costs also include
capital and operating costs paid (e.g., drilling, production and other direct costs of owning and operating the property) and a monthly overhead charge that is adjusted annually. The monthly overhead charge at December&nbsp;31, 2006 was $25,308
($18,981 net to the trust). XTO Energy also deducts an overhead charge as operator of the Penwell Unit. As of December&nbsp;31, 2006, monthly overhead attributable to the Penwell Unit was $2,470 ($1,852 net to the trust). If production costs exceed
gross proceeds for any conveyance, this excess is carried forward to future monthly computations of net proceeds until the excess costs (plus interest accrued as specified in the conveyances) are completely recovered. Excess production costs and
related accrued interest from one conveyance cannot be used to reduce net proceeds from any other conveyance. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

instability in oil-producing regions, worldwide economic conditions, weather conditions, the supply and price of domestic and foreign oil and natural gas, consumer demand, the price and availability of alternative fuels, the proximity to, and
capacity of, transportation facilities and the effect of worldwide energy conservation measures. Moreover, government regulations, such as regulation of natural gas transportation and price controls, can affect product prices in the long term. Lower
oil and natural gas prices may reduce the amount of oil and natural gas that is economic to produce and will reduce net profits available to the trust. The volatility of energy prices reduces the predictability of future cash distributions to trust

FACE="Times New Roman" SIZE="2">Estimating proved oil and gas reserves is inherently uncertain. Petroleum engineers consider many factors and make assumptions in estimating reserves and future net cash flows. Those factors and assumptions include
historical production from the area compared with production rates from similar producing areas, the effects of governmental regulation, assumptions about future commodity prices, production expense and development costs, taxes and capital
expenditures, the availability of enhanced recovery techniques and relationships with landowners, working interest partners, pipeline companies and others. Lower oil and gas prices generally cause lower estimates of proved reserves. Ultimately,
actual production, revenues and expenditures for the underlying properties will vary from estimates and those variances could be material. Because the trust owns net profits interests, it does not own a specific percentage of the oil and gas
reserves. Estimated proved reserves for the net profits interests are based on estimates of reserves for the underlying properties and an allocation method that considers estimated future net proceeds and oil and gas prices. Because trust reserve
quantities are determined using an allocation formula, increases or decreases in oil and gas prices can significantly affect estimated reserves of the 75% net profits interests. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT

San Juan Basin. Revisions of prior estimates are primarily related to changes in year-end prices and costs. See &#147;General&#148; above. As of December&nbsp;31, 2005 and 2006, proved reserves for the underlying properties and attributable to the
90% net profits interests have been reduced to reflect anticipated payout under the reversion agreement in which 25% of XTO Energy&#146;s interest in certain underlying royalties will transfer to a third party when payout occurs. See &#147;Reversion
Agreement&#148; below. Year-end 2005 was the first time estimated proved reserves were adjusted for the effect of the reversion agreement, since anticipated payout was accelerated in 2005 by higher product prices and increased development of
properties subject to the reversion agreement. The effect of anticipated payout was to reduce December&nbsp;31, 2005 gas reserves for the underlying properties and net profits interests by approximately 2%, oil reserves for the underlying properties
by approximately 4% and oil reserves for the net profits interests by approximately 6%. The effect of the reversion agreement is included in 2005 revisions and is offset by increased reserves related to higher year-end product prices. </FONT></P> <P

subject to a reversion agreement between XTO Energy and an unrelated third party. The agreement calls for XTO Energy to transfer 25% of its interest in those properties to the third party when net amounts received by XTO Energy from the properties
subject to the agreement equal the purchase price of the properties plus a 1%&nbsp;per month return on the unrecouped purchase price, known as payout. At the time payout occurs and the 25% interest is transferred to the third party, net proceeds
payable to the trust and trust distributions to unitholders will be reduced. Based on recent prices and sales volumes, XTO Energy has informed the trustee that payout could occur by the end of 2007, thereafter reducing monthly distributions by
approximately 5%. Payout is affected by product prices and the level of development of properties subject to the reversion agreement. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P

developing new fields, the spacing and operation of wells and the prevention of waste of oil and gas resources. The rates of production may be regulated and the maximum daily production allowables from both oil and gas wells may be established on a
market demand or conservation basis, or both. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px; margin-left:2%"><FONT FACE="Times New Roman" SIZE="2"><I>State Income

legislation to implement a new margin tax of 1% to be imposed on revenues less certain costs, as specified in the legislation, generated from Texas activities beginning in 2007. Entities subject to the tax generally include trusts, unless otherwise
exempt, and various other types of entities. Trusts that meet statutory requirements are generally exempt from the margin tax as &#147;passive entities&#148;; however, there is currently no clear authority that the trust meets requirements for the
margin tax exemption as a passive entity. Additional legislative action or issuance of applicable administrative rules by the state comptroller may be necessary to determine if the trust is exempt. The trust does not currently intend to pay the
margin tax, based on the assumption that it is exempt as a passive entity. However, if it is subsequently determined that the trust is not exempt from the margin tax, the trust would be required to deduct and withhold from future distributions the
amounts necessary to pay the margin tax for the entire 2007 year, including the tax liability accruing on income distributed after January 2007 from which no tax was withheld. Approximately 30% of the trust&#146;s net profits income is generated
from underlying properties in Texas. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px; text-indent:4%"><FONT FACE="Times New Roman" SIZE="2">If the trust is exempt
from the margin tax at the trust level as a passive entity, each unitholder that is a taxable entity would generally include its share of the trust&#146;s revenues in its margin tax computation. If, however, the margin tax is imposed on the trust at
the trust level, each unitholder subject to the margin tax would generally exclude its share of the trust&#146;s net income from the margin tax calculation. Unitholders should consult their tax advisors regarding their individual tax situation.

the results of drilling, testing and production subsequent to the date of an estimate, as well as economic factors such as changes in product prices, may justify revision of such estimates. Because proved reserves are required to be estimated using
prices at the date of the evaluation, estimated reserve quantities can be significantly impacted by changes in product prices. Accordingly, oil and gas quantities ultimately recovered and the timing of production may be substantially different from

receive a share of the net profits from oil and gas production from the underlying properties. Consequently, the trust is exposed to market risk from fluctuations in oil and gas prices. The trust is a passive entity and, other than the trust&#146;s
ability to periodically borrow money as necessary to pay expenses, liabilities and obligations of the trust that cannot be paid out of cash held by the trust, the trust is prohibited from engaging in borrowing transactions. The amount of any such
borrowings is unlikely to be material to the trust. In addition, the trustee is prohibited by the trust indenture from engaging in any business activity or causing the trust to enter into any investments other than investing cash on hand in specific
short-term cash investments. Therefore, the trust cannot hold any derivative financial instruments. As a result of the limited nature of its borrowing and investing activities, the trust is not subject to any material interest rate market risk.
Additionally, any gains or losses from any hedging activities conducted by XTO Energy are specifically excluded from the calculation of net proceeds due the trust under the forms of the conveyances. The trust does not engage in transactions in
foreign currencies which could expose the trust to any foreign currency related market risk. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P>

generated from Texas activities beginning in 2007. Entities subject to the tax generally include trusts, unless otherwise exempt, and various other types of entities. Trusts that meet statutory requirements are generally exempt from the margin tax
as &#147;passive entities&#148;; however, there is currently no clear authority that the trust meets requirements for the margin tax exemption as a passive entity. Additional legislative action or issuance of applicable administrative rules by the
state comptroller may be necessary to determine if the trust is exempt. The trust does not currently intend to pay the margin tax, based on the assumption that it is exempt as a passive entity. However, if it is subsequently determined that the
trust is not exempt from the margin tax, the trust would be required to deduct and withhold from future distributions the amounts necessary to pay the margin tax for the entire 2007 year, including the tax liability accruing on income distributed
after January 2007 from which no tax was withheld. Approximately 30% of the trust&#146;s net profits income is generated from underlying properties in Texas. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P> <P
