SPECIAL NOTE

        The filing of this Quarterly Report as well as the Trust's Annual Report on Form 10-K for the year ended December 31, 2006 was delayed as a result of issues regarding certain overpayments to the Trust and related issues regarding the Trust's ownership of certain assets. As a result of those issues, the Trustee of Santa Fe Energy Trust concluded on May 1, 2007 that the Trust's previously-issued financial statements should no longer be relied upon, as set forth in the Trust's Report on Form 8-K filed on May 3, 2007. The Trustee subsequently determined to restate the Trust's financial statements for the years ended December 31, 2005 and 2004. The restated financial statements are included in the Trust's Annual Report on Form 10-K for the year ended December 31, 2006, and the restated financial statements should be read in conjunction with this Quarterly Report.

        On December 19, 2007, the Trust consummated the sale of all or substantially all of its assets to Amen Properties, Inc. and certain other purchasers for approximately $51.5 million, and, in accordance with the Trust's governing documents, the Trust liquidated on or about February 15, 2008. Unitholders of record on February 14, 2008 received a terminating distribution with respect to each Depositary Unit equal to a pro rata portion of the net proceeds from the sale of the Net Profits Royalties (subject to reserves for expenses and contingencies) and a pro rata portion of the proceeds from the matured Treasury Obligations. The distributions were made soon after the February 15, 2008 liquidation. The Trust ceased operations subsequent to the distribution.

        Trading in the Depositary Units was halted at the close of business on February 14, 2008, and the Depositary Units were delisted by the New York Stock Exchange at the same time. The Trust's reporting obligations under the Securities Exchange Act of 1934, as amended, subsequently terminated.

SANTA FE ENERGY TRUST

NOTES TO FINANCIAL STATEMENTS (Unaudited)

Note 1. Summary of Significant Accounting Policies

        The financial statements of the Trust are prepared on the cash basis of accounting for revenues and expenses. Royalty income is recorded when received (generally during the quarter following the end of the quarter in which the income from the Royalty Properties is received by Devon Energy Corporation ("Devon")) and is net of any cash basis exploration and development expenditures and amounts reserved for any future exploration and development costs. Expenses of the Trust, which include accounting, engineering, legal and other professional fees, Trustee fees, an administrative fee paid to Devon and out-of-pocket expenses, are recognized when paid. Under accounting principles generally accepted in the United States of America, revenues and expenses would be recognized on an accrual basis. Amortization of the Trust's investment in Royalty Interests is recorded using the unit-of-production method in the period in which the cash is received with respect to such production; therefore, a statement of cash flows is not presented.

        The Trust is a grantor trust and as such is not subject to income taxes and accordingly no recognition has been given to income taxes in the Trust's financial statements. The tax consequences of owning Trust Units are included in the income tax returns of the individual Trust Unit holders.

        The preparation of the Trust's financial statements requires the use of certain estimates. Actual results may differ from such estimates.

        In the opinion of the Trustee, all adjustments (all of which are normal and recurring) have been made which are necessary to fairly state the financial position, cash proceeds and distributable cash of the Trust.

        The accompanying financial statements and notes thereto should be read in conjunction with the financial statements and notes thereto and other information included in the Trust's 2006 Annual Report on Form 10-K.

NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued)

Note 2. Distributions to Trust Unit Holders

        The Trust has received royalty payments net of administrative fees paid to Devon and made distributions as follows:

---

(a)

Includes proceeds from the sale of Net Profits properties of $0.4 million or $0.05643 per Trust Unit.

(b)

Includes proceeds from the sale of Net Profits properties of $0.1 million or $0.02000 per Trust Unit.

Note 3. Commitments and Contingencies

        The Royalty Properties related to the Trust are the subject of lawsuits and governmental proceedings from time to time arising in the ordinary course of business. While the outcome of lawsuits or other proceedings involving the Royalty Properties cannot be predicted with certainty, these matters are not expected to have a material adverse effect on the financial position or cash proceeds and distributable cash of the Trust.

Note 4. Restatement of Previously Reported Amounts (Unaudited)

        In April 2006, in preparation for the Trust's sale of the Net Profits Royalties in accordance with the Trust Agreement, Devon began a review of its files relating to the Net Profits Royalties. As a result of this review which continued through the remainder of 2006 and most of 2007, Devon identified a number of interests in the Net Profits Royalties which were not actually held by the Trust but which had been reported as being owned by the Trust. Consequently, Devon concluded that it had overpaid the Trust approximately $10.6 million over the seven-year period ended December 31, 2006. An independent oil and gas auditing firm retained by the Trustee to review the work performed by Devon and its independent oil and gas title consultants confirmed to the Trustee that Devon did make such overpayments to the Trust.

Note 4. Restatement of Previously Reported Amounts (Unaudited) (Continued)

        Beginning with the distribution paid in May 2007, Devon began to withhold amounts otherwise distributable to the Trust on the Net Profits Royalties in order to recoup a portion of the amount Devon had overpaid the Trust. The aggregate amount Devon recouped through the distribution paid in February 2008 was approximately $7.7 million.

        On May 1, 2007, as a result of the matters described above, the Trustee concluded, based on the information furnished to the Trustee by Devon as described above, that the Trust's previously issued financial statements, which include supplemental oil and gas reserve information, should no longer be relied upon. The Trustee subsequently determined to restate the Trust's financial statements for the years ended December 31, 2005 and 2004.

        As stated in Note 1, the financial statements of the Trust are prepared on the cash basis of accounting. Therefore, the error described above does not impact previously reported distributions for the seven-year period ended December 31, 2006. However, amounts previously reported for royalty income received and administrative fees paid to Devon during this time period were overstated. The adjustments that were made to correct this error in the accompanying 2006 Statement of Cash Proceeds and Distributable Cash are summarized below.

        Additionally, amounts previously reported for amortization of royalty interests during the seven-year period ended December 31, 2006 were also misstated. This error also caused a similar

overstatement of trust corpus. The adjustments that were made to correct this error in the accompanying 2006 Statement of Changes in Trust Corpus are summarized below.

Note 5. Subsequent Event (Unaudited)

        On December 19, 2007, the Trustee announced that it completed the sale of all of the Net Profits Royalties held by the Trust to Amen Properties, Inc. and certain other purchasers. The aggregate price for the assets sold was approximately $51.5 million, after making adjustments pursuant to the purchase agreement.

        The Trustee distributed the net proceeds of the sale (after deducting amounts necessary to pay all fees, expenses, liabilities and other obligations of the Trust, and after setting aside any amounts the Trustee determined to hold in reserve, and subject to post-closing adjustments under the purchase agreement) on February 29, 2008 to unitholders of record at the close of business on February 14, 2008. The distribution was made concurrently with the Trust's distribution for the quarter ending December 31, 2007.

        The United States Treasury book-entry securities representing stripped-interest coupons held by the Trustee as Custodian matured on February 15, 2008. Unitholders of record at the close of business on February 14, 2008 were entitled to receive the cash proceeds from the matured Treasury Obligations on deposit with the Custodian. The cash proceeds were distributed as promptly as practicable on or after February 15, 2008.

        The Trust was liquidated on February 15, 2008 and ceased operations. After that date the Trustee continued to act as trustee of the trust estate for purposes of distributing the trust estate and winding up the affairs of the Trust.

        The Trustee instructed the Trust's transfer agent to stop transfer of the Trust's units immediately following the close of business on February 14, 2008 and requested that the New York Stock Exchange delist the units at that time. The Trust's reporting obligations under the Securities Exchange Act of 1934, as amended, subsequently terminated.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

        The following discussion addresses material changes in results of operations for the three months ended March 31, 2007, compared to the three months ended March 31, 2006 and in financial condition since December 31, 2006. It is presumed that readers have read or have access to the Trust's 2006 Annual Report on Form 10-K which includes disclosures regarding critical accounting policies as part of Management's Discussion and Analysis of Financial Condition and Results of Operations.

        The Trust terminated and the Net Profits Royalties were sold on December 19, 2007. Each holder of Depositary Units of record as of the day next preceding the Liquidation Date was entitled to receive a liquidating distribution equal to (1) $20 per Depositary Unit from the proceeds of the matured Treasury Obligations, plus (2) a pro rata portion of the net proceeds from the sale of Net Profits Royalties, to the extent not previously distributed. Following the Liquidation Date, Holders were no longer entitled to receive quarterly distributions and the Depositary Units ceased trading. Please read "Description of the Trust Units and Depositary Units—Termination and Liquidation of the Trust" in the Trust's 2006 Annual Report on Form 10-K.

General; Liquidity and Capital Resources

        The Trust's results of operations were dependent upon the sales prices and quantities of oil and gas produced from the Royalty Properties, the costs of producing such resources and the amount of capital expenditures made with respect to such properties.

        Since, on an equivalent basis, the majority of the Trust's proved reserves are crude oil, even relatively modest changes in crude oil prices may significantly affect the Trust's revenues and results of operations. Crude oil prices are subject to significant changes in response to fluctuations in the domestic and world supply and demand and other market conditions as well as the world political situation as it affects OPEC and other oil producing countries. In addition, a substantial portion of the Trust's revenues come from properties which produce sour (i.e., high sulfur content) crude oil which sells at prices lower than sweeter (i.e., low sulfur content) crude oils.

        Natural gas prices fluctuate due to weather conditions, the level of natural gas in storage, the relative balance between supply and demand and other economic factors.

        Trust expenses included accounting, engineering, legal and other professional fees, Trustee fees, an administrative fee paid to Devon and other out-of-pocket expenses. The Trust's ability to pay expenses primarily depended on receipt of royalty income. Devon had the ability, at its sole discretion and without obligation to do so, to advance funds to the Trust to enable the Trust to pay expenses. The Trustee was authorized to borrow funds required to pay liabilities of the Trust, provided that any such borrowings were repaid in full prior to making further distributions to Holders. As of March 31, 2007, Devon had no outstanding advances to the Trust.

Results of Operations

        Royalty income is recorded by the Trust when received, generally during the quarter following the end of the quarter in which revenues are received and costs and expenses are paid by Devon. Cash proceeds from the Royalty Properties may fluctuate from quarter to quarter due to the timing of receipts and payment of revenues and costs and expenses as well as changes in prices and production volumes. The following table reflects pertinent information with respect to the cash proceeds from the Royalty Properties and the net distributable cash of the Trust. The information presented with respect to the second quarter of 2007 reflects revenues received and costs and expenses paid by Devon in the first quarter of 2007. On May 31, 2007, the Trust made a cash distribution of $2.6 million, or $0.40513 per Trust Unit, to unitholders of record on May 15, 2007.

10

---

        Sales decreased $0.7 million from the first quarter of 2006 to the first quarter of 2007. Sales increased $0.1 million due to a $0.56 per barrel increase in the average price of oil from $53.94 per barrel in the first quarter of 2006 to $54.50 per barrel in the first quarter of 2007. Sales decreased $0.6 million due to a $2.54 per Mcf decrease in the average gas price from $7.98 per Mcf in the first quarter of 2006 to $5.44 in the first quarter of 2007. Production on a barrels of oil equivalent ("Boe") basis from the first quarter of 2006 to the first quarter of 2007 decreased approximately 4,000 Boe, causing sales to decrease $0.2 million. This decrease in production was primarily the result of the sale of certain Net Profits Properties in 2005, timing of receipts and natural production declines.

        Sales decreased $1.0 million from the first quarter of 2007 to the second quarter of 2007. A production decrease of approximately 18,000 Boe in the second quarter of 2007, as compared to the first quarter of 2007, caused sales to decrease by $0.8 million. The decrease in production was due to a 2,000 barrel reduction in the Wasson ODC royalty due to certain quarterly limitations set forth in the conveyance agreement, natural production declines and timing of receipts. This was further reduced by an decrease in sales of $0.2 million due to a $0.51 per Mcf increase in the average gas price from $5.44 per Mcf in the first quarter of 2007 to $5.95 per Mcf in the second quarter of 2007 offset by a $3.15 per barrel decrease in the average price of oil from $54.50 per barrel in the first quarter of 2007 to $51.35 per barrel in the second quarter of 2007.

        Operating expenses increased $0.1 million from the first quarter of 2006 to the first quarter of 2007. Operating expenses decreased $0.2 million from the first quarter of 2007 to the second quarter of 2007.

        Proceeds from the Net Profits Royalties are net of capital expenditures with respect to the development of the Net Profits Properties. Capital expenditures were $47,000 for the first quarter of 2007 compared to capital recoveries of $443,000 for the first quarter of 2006. Capital expenditures were $11,000 for the second quarter of 2007.

Overpayments of Previous Distributions and Subsequent Recoupments

        In March 2007, in preparation for the Trust's sale of the Net Profits Royalties in conjunction with the liquidation of the Trust, Devon began a review of its files relating to the Net Profits Royalties. As a result of this review, Devon identified a number of overpayments it had made to the Trust related to royalty interests that the Trust did not actually own. Devon determined and the Trustee ultimately agreed that for the seven-year period ended December 31, 2006 the Trust had been overpaid by approximately $10.6 million. The portion of this total overpayment that relates to 2006, 2005 and 2004 was $0.3 million, $3.0 million and $4.4 million, respectively.

        Throughout 2007 Devon recouped approximately $7.7 million of the overpayments as allowed by the conveyances to the Trust.

Sale of Net Profits Royalties

        On December 19, 2007, the Trustee announced that it had completed the sale of all of the Net Profits Royalties held by the Trust to Amen Properties, Inc. and certain other purchasers. The aggregate price for the assets sold was approximately $51.5 million, after making adjustments pursuant to the purchase agreement.

---

        The Trustee distributed the net proceeds of the sale (after deducting amounts necessary to pay all fees, expenses, liabilities and other obligations of the Trust, and after setting aside any amounts the Trustee determined to hold in reserve, and subject to post-closing adjustments under the purchase agreement) on February 29, 2008 to unitholders of record at the close of business on February 14, 2008. The distribution was made concurrently with the Trust's distribution for the quarter ending December 31, 2007.

        The United States Treasury book-entry securities representing stripped-interest coupons held by the Trustee as Custodian matured on February 15, 2008. Unitholders of record at the close of business on February 14, 2008 were entitled to receive the cash proceeds from the matured Treasury Obligations on deposit with the Custodian. The cash proceeds were distributed as promptly as practicable on or after February 15, 2008.

        The Trust was liquidated on February 15, 2008. After that date the Trustee continued to act as trustee of the trust estate for purposes of distributing the trust estate and winding up the affairs of the Trust.

        The Trustee instructed the Trust's transfer agent to stop transfer of the Trust's units immediately following the close of business on February 14, 2008 and requested that the New York Stock Exchange delist the units at that time. The Trust's reporting obligations under the Securities Exchange Act of 1934, as amended, subsequently terminated.

Forward Looking Statements

        Management's Discussion and Analysis of Financial Condition and Results of Operations includes certain statements (other than statements of historical fact) that constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. When used herein, the words "anticipates," "expects," "believes," "intends" or "projects" and similar expressions are intended to identify forward-looking statements. It is important to note that actual results could differ materially from those projected by such forward-looking statements. Although it is believed that the expectations reflected in such forward-looking statements are reasonable and such forward-looking statements are based upon the best data available at the time this report is filed with the Securities and Exchange Commission, no assurance can be given that such expectations will prove correct. All such forward-looking statements in this document are expressly qualified in their entirety by the cautionary statements in this paragraph.

Item 4. Controls and Procedures

(a)   Background

        As a result of the issues described in the Trust's Annual Report on Form 10-K for the year ended December 31, 2006 (the "2006 Annual Report") and in the Trust's prior Current Reports on Form 8-K regarding certain overpayments Devon made to the Trust and related issues regarding the Trust's ownership of certain assets, the Trustee of the Trust concluded on May 1, 2007 that the Trust's

12

---

previously-issued financial statements should no longer be relied upon, as set forth in the Trust's Report on Form 8-K filed on May 3, 2007. The Trustee subsequently determined to restate the Trust's financial statements for the years ended December 31, 2005 and 2004 to identify overpayments made to the Trust. The restated financial statements are included in the Trust's 2006 Annual Report. The adjustments made as a result of the restatement are more fully discussed in Note 8 of the Notes to the Financial Statements of Santa Fe Energy Trust for the year ended December 31, 2006 and in Part II—Item 7—"Management's Discussion and Analysis of Financial Condition and Results of Operations" included in the Trust's Annual Report.

        As a result of the restatement and the issues leading to the restatement, the Trustee has identified deficiencies in the Trust's internal control over financial reporting that led to the failure to prevent or detect the errors which led to the restatement. The Trustee has concluded that the control deficiencies represented a material weakness in the Trust's internal control over financial reporting. These matters are discussed more fully below.

(b)   Disclosure Controls and Procedures

        The Trust maintains disclosure controls and procedures designed to ensure that information required to be disclosed by the Trust in the reports that it files or submits under the Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and regulations. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed by the Trust is accumulated and communicated by Devon to The Bank of New York Mellon Trust Company, N.A., as Trustee of the Trust, and its employees who participate in the preparation of the Trust's periodic reports as appropriate to allow timely decisions regarding required disclosure.

        As of the end of the period covered by this report, the Trustee carried out an evaluation of the Trust's disclosure controls and procedures. Based upon that evaluation and the restatement of the Trust's financial statements as described above, which arose from the material weakness in internal control over financial reporting described herein, Mike Ulrich, as Trust Officer of the Trustee, has concluded that the Trust's disclosure controls and procedures were not effective as of March 31, 2007. However, based on the additional procedures performed by Devon and the independent consultants retained by Devon during 2007, and the additional procedures performed by the independent oil and gas auditing firm retained by the Trustee to review the work performed by Devon and its consultants, the Trustee believes that the financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, the financial position and results of operations and cash flows of the Trust as of the dates, and for the periods presented in accordance with generally accepted accounting principles.

        Due to the contractual arrangements of (i) the Trust Agreement and (ii) Devon's conveyances of the Royalty Interests to the Trust regarding information furnished by the working interest owners, the Trustee historically relied on (i) information provided by Devon and the working interest owners, including all information relating to the Royalty Properties burdened by the Royalty Interests, such as operating data, data regarding operating and capital expenditures, geological data relating to reserves, information regarding environmental and other conditions relating to the Royalty Properties, liabilities and potential liabilities potentially affecting the revenues to the Trust's interest, the effects of regulatory changes and of the compliance of the operators of the Royalty Properties with applicable laws, rules and regulations, the number of producing wells and acreage, and plans for future operating and capital

13

---

expenditures, and (ii) conclusions of independent reserve engineers regarding reserves. The conclusions of the independent reserve engineers are based on information received from Devon and the working interest owners.

        Prior to 2007, the Trustee reviewed the quarterly information provided to the Trustee by Devon, as well as the annual information provided to the Trustee by the Trust's independent reserve engineers regarding reserves, and discussed the information as it deemed appropriate with representatives of Devon and the engineers. However, prior to 2007, as previously disclosed, the Trustee ultimately relied on the information provided and did not have controls or procedures in place to verify certain of the accuracy of the information Devon provided to the Trustee or that Devon provided to the engineers. Specifically, the Trustee did not have internal controls or procedures in place to verify that the information Devon furnished to the Trust's independent petroleum engineers was accurate or that the quarterly payments Devon made to the Trust under the Conveyances to the Trust were complete and related to specific properties in which the Trust held an interest.

(c)   Changes in Internal Control Over Financial Reporting.

        During 2007 (including the period covered by this report) there were changes in the Trust's internal control over financial reporting that materially affected the Trust's internal control over financial reporting. As a result of the material weakness described in the 2006 Annual Report, in addition to committing internal resources to the review, Devon retained independent oil and gas title consultants from two consulting firms, which reviewed Devon's title files relating to the Trust, to determine whether Devon had actually included interests not owned by the Trust in the reports previously sent to the Trustee and to the Trust's independent petroleum engineers, and whether it had actually overpaid the Trust. In addition, the Trustee retained outside consultants to review the work being performed by Devon and its outside consultants. In the opinion of the Trustee, the reviews conducted by Devon and the consulting firms it retained and the review conducted by the consulting firm retained by the Trustee, materially affected the Trust's internal control over financial reporting during 2007, including the period covered by this report.
