TRI-VALLEY CORPORATION

NOTES TO CONDENSED FINANCIAL STATEMENTS

FOR THE THREE MONTHS ENDED

March 31, 2007 and 2006

(Unaudited)

NOTE 1 - DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Description of Business

Tri-Valley Corporation (“TVC” or the Company), a Delaware corporation formed in 1971, is in the business of exploring, acquiring and developing petroleum and metal and mineral properties and interests therein. Tri-Valley has five subsidiaries and four operating segments or business lines.

·   Tri-Valley Oil & Gas Company (“TVOG”) operates the oil & gas activities. TVOG derives the majority of its revenue from oil and gas drilling and turnkey development. TVOG primarily generates its own exploration prospects from its internal database, and also screens prospects from other geologists and companies. TVOG generates these geological “plays” within a certain geographic area of mutual interest. The prospect is then presented to potential co-ventures. The company deals with both accredited individual investors and energy industry companies. TVOG serves as the operator of these co-ventures. TVOG operates both the oil and gas production segment and the drilling and development segment of our business lines.

·   Select Resources Corporation (“Select”) was created in late 2004 to manage, grow and operate Tri-Valley’s mineral interests. Select operates the minerals segment of our business lines.

·   Great Valley Production Services, LLC, (“GVPS”) was formed in 2006 to operate oil production services, well work over and drilling rigs, primarily for TVOG. However, from time to time TVOG may contract various units to third parties when not immediately needed for TVOG projects. Tri-Valley has sold 49% of the ownership interest to private parties and has retained a 51% ownership interest in this subsidiary. Operations began in the third quarter of 2006.

·   Great Valley Drilling Company, LLC (“GVDC”) was formed in 2006 to operate oil drilling rigs, primarily in Nevada where Tri-Valley has 17,000 acres of prospective oil leases. However, because rig availability is so extremely scarce in Nevada, GVDC has an exceptional opportunity to do contract drilling for third parties in both petroleum and geothermal projects. For the time being GVDC, whose operation began in the first quarter of 2007, expects its primary activity will be contract drilling for third parties. Tri-Valley has sold 49% of the ownership interest to private parties and has retained a 51% ownership interest in this subsidiary. TVC is exercising its option to buy back the minority interest in GVDC and expects to be finalized by the end of June 2007, at which time GVDC will be 100% owned by TVC. The repurchase cost is expected to be about $1.7 million.

·   Tri-Valley Power Corporation is inactive at the present time.

Basis of Presentation

The financial information included herein is unaudited; however, such information reflects all adjustments (consisting solely of normal recurring adjustments), which are, in the opinion of management, necessary for a fair statement of results for the interim periods. The results of operations for the three-month period ended March 31, 2007, are not necessarily indicative of the results to be expected for the full year.

The accompanying consolidated financial statements do not include footnotes and certain financial presentations normally required under generally accepted accounting principles in the United States of America; and, therefore, should be read in conjunction with our Annual Report on Form 10-K, filed with the Securities and Exchange Commission on March 31, 2007, for the year ended December 31, 2006.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, TVOG, Select, Tri-Valley Power Corporation, since their inception. GVPS and GVDC, where the Company has retained a 51% ownership interest, are also included in the consolidation. Other partnerships in which the Company has an operating or nonoperating interest in which the Company is not the primary beneficiary and owns less than 51%, are proportionately combined. This includes Opus I, Martins-Severin, Martins-Severin Deep, and Tri-Valley Exploration 1971-1 partnerships. All material intra and intercompany accounts and transactions have been eliminated in combination and consolidation.

NOTE 2 - PER SHARE COMPUTATIONS

Per share computations are based upon the weighted-average number of common shares outstanding during each year. Common stock equivalents are not included in the computations since their effect would be anti-dilutive.

NOTE 3 - SUMMARY OF RECENTLY ISSUED ACCOUNTING PRONOUCEMENTS

Asset Retirement Obligation

In March 2005, the Financial Accounting Standards Board issued FASB Interpretation No. 47, “Accounting for Conditional Asset Retirement Obligations”, Under the provisions of FIN No. 47, the term conditional asset retirement obligation as used in SFAS No. 143, “Accounting for Asset Retirement Obligations”, refers to a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity while the obligation to perform the asset retirement activity is unconditional. Accordingly, an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. The fair value of a liability for the conditional asset retirement obligation is required to be recognized when incurred—generally upon acquisition, construction, or development and/or through the normal operation of the asset. We have adopted FIN No. 47 as of December 31, 2005. Adoption of this pronouncement did not have a significant effect on our 2005 or 2006 consolidated financial statements, and we do not expect this pronouncement to have a significant effect on our future reported financial position or earnings.

Accounting Changes

In May 2005, SFAS No. 154, Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3 was issued. SFAS No. 154 requires retrospective application to prior period financial statements for changes in accounting principles, unless it is impractical to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle should be recognized in the period of the accounting change. SFAS No. 154 became effective for our fiscal year beginning January 1, 2006. There was no effect for our fiscal year ending December 31, 2006, and we do not expect this pronouncement to have a significant effect on our future reported financial position or results of operations.

NOTE 3 - Recently Issued Accounting Pronouncements (Continued)

Accounting for Uncertainty in Income Taxes

In July 2006, the Financial Accounting Standards Board (“FASB”) issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes - An interpretation of FASB Statement No. 109” (“FIN 48”).

This Interpretation provides a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. We adopted this Interpretation in the first quarter of 2007 with no effect to the Company and do not expect the adoption to have a material impact on our financial position or results of operations.

Fair Value Measurements

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” This Statement replaces multiple existing definitions of fair value with a single definition, establishes a consistent framework for measuring fair value and expands financial statement disclosures regarding fair value measurements. This Statement applies only to fair value measurements that already are required or permitted by other accounting standards and does not require any new fair value measurements. SFAS No. 157 is effective for fiscal years beginning subsequent to November 15, 2007. We will adopt this Statement in the first quarter of 2008 and do not expect the adoption to have a material impact on our financial position or results of operations.

Effects of Prior Year Misstatements

In September 2006, Staff Accounting Bulletin (“SAB”) No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements.” Registrants must quantify the impact on current period financial statements of correcting all misstatements, including both those occurring in the current period and the effect of reversing those that have accumulated from prior periods. This SAB was adopted at December 31, 2006. The adoption of SAB No. 108 had no effect on our financial position or on the results of our operations.

The Fair Value Option for Financial Assets and Financial Liabilities

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities,” which permits an entity to measure certain financial assets and financial liabilities at fair value. The objective of SFAS No. 159 is to improve financial reporting by allowing entities to mitigate volatility in reported earnings caused by the measurement of related assets and liabilities using different attributes, without having to apply complex hedge accounting provisions. Under SFAS No. 159, entities that elect the fair value option (by instrument) will report unrealized gains and losses in earnings at each subsequent reporting date. The fair value option election is irrevocable, unless a new election date occurs. SFAS No. 159 establishes presentation and disclosure requirements to help financial statement users understand the effect of the entity’s election on its earnings, but does not eliminate disclosure requirements of other accounting standards. Assets and liabilities that are measured at fair value must be displayed on the face of the balance sheet. This statement is effective beginning January 1, 2008; We are evaluating this pronouncement, but do not expect the adoption to have a material impact on our financial position or results of operations.

Change in Categorization of Rigs

Due to our rapidly growing rig operations, we created a separate category for our rig equipment. In the first quarter of 2006 rig equipment was included in other property and equipment. For comparability purposes, those amounts are now shown separately.

10

NOTE 4 - NOTES PAYABLE

In January 2007, a note payable to Gary D. Borgna and Julie R. Borgna, and Equipment 2000 secured by rig equipment in the amount of $300,000 was paid. Mr. Borgna is the general manager of GVDC.

In March 2007, a promissory note issued to F. Lynn Blystone and Patricia L. Blystone in the amount of $150,000 was paid in full. Mr. Blystone is the Chairman, President and Chief Executive Officer of Tri-Valley Corporation.

NOTE 5 - CHANGES IN SECURITIES

Common Stock

During the first quarter of 2007, the Company issued 990,596 shares of common stock. Three employees exercised employee stock options issued in previous years to purchase 3,000 shares of common stock totaling $1,500. An employee exercised stock options in a cashless exercise for 12,935 shares of common stock. A former director exercised his stock options and was issued 270,000 shares for a total consideration of $348,000. The Company’s directors received 10,000 shares for services. We issued 33,333 shares of stock upon the exercise of warrants which were issued in 2006. These warrants were exercised at $9.00 per share for a total consideration of $299,997. The remaining 661,328 shares were issued in private placements at prices of $8.00 and $8.50 per share, for a total consideration of $5,590,624. Total stock issuance cost for the first quarter was $706,875.

Warrants

During the first quarter of 2007, the Company issued warrants to accredited investors in conjunction with the sale of 661,661 shares of restricted common stock. 220,443 warrants were attached to these restricted shares. The warrants are exercisable for a period of two years from the date of issuance. The warrants are exercisable at $9.50 to $10.00, depending on when they were issued. The warrants were valued using the Black-Scholes option-pricing model, which resulted in charges to additional paid in capital of $533,179 and resulted in charges to stock issuance expense of $272,542.

Warrants are accounted for under the guidelines established by APB Opinion No. 14 Accounting for Convertible Debt and Debt issued with Stock Purchase Warrants (APB14) under the direction of Emerging Issues Task Force (EITF) 98-5, Accounting for Convertible Securities with Beneficial Conversion Features or Contingently Adjustable Conversion Ratios, (EITF 98-5) EITF 00-27 Application of Issue No 98-5 to Certain Convertible Instruments and (EITF 00-27. The Company calculates the fair value of warrants issued with the convertible instruments using the Black-Scholes valuation method, using the same assumptions used for valuing employee options for purposes of SFAS No. 123R, except that the expected life of the warrant is used. Under these guidelines, the Company allocates the value of the proceeds received. The price allocated for the warrants is calculated by subtracting the current market price of the stock from the total proceeds of the sale of the restricted stock with the warrant attached. The allocated fair value is recorded as capital paid in - warrants. This allocated fair value of the proceeds from the sale of warrants is subtracted from the value of the warrants using the Black-Scholes valuation method to calculate the stock issuance expense.

NOTE 6 - STOCK BASED COMPENSATION EXPENSE

Stock Based Compensation

Compensation expense charged against income for stock based awards in the first quarter of 2007 and 2006 was $231,949 and $52,060, pre-tax, respectively, and is included in general and administrative expense in the Consolidated Statement of Operations.

11

NOTE 6 - STOCK BASED COMPENSATION EXPENSE (Continued)

For further information regarding stock based compensation, please refer to Note 5 of the Notes to the Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended December 31, 2006.

NOTE 7 - FINANCIAL INFORMATION RELATING TO INDUSTRY SEGMENTS

The Company reports operating segments according to SFAS No. 131, “Disclosure about Segments of an Enterprise and Related Information”.

The Company identifies reportable segments by products and services. The Company includes revenues from both external customers and revenues from transactions with other operating segments in its measure of segment profit or loss.

The Company’s operations are classified into four principal industry segments:
-	Oil and gas operations include our share of revenues from oil and gas wells on which TVOG serves as operator, royalty income and production revenue from other partnerships in which we have operating or non-operating interests. It also includes revenues for consulting services for oil and gas related activities.
-	Rig operations began in 2006, when the Company acquired drilling rigs and began operating them through subsidiaries GVPS and GVDC. Rig operations include income from rental of oil field equipment.
-	Minerals include the Company’s mining and mineral prospects and operations, and expenses associated with those operations. In 2006, the Company recorded minerals revenue from consulting services performed for the mining and minerals industry, which are included on the operating statement as other income.
-	Drilling and development includes revenues received from oil and gas drilling and development operations performed for joint venture partners, including the Opus-I drilling partnership.

Notice Regarding Forward-Looking Statements

This report contains forward-looking statements. The words, "anticipate," "believe," "expect," "plan," "intend," "estimate," "project," "could," "may," "foresee," and similar expressions are intended to identify forward-looking statements. These statements include information regarding expected development of Tri-Valley's business, lending activities, relationship with customers, and development in the oil and gas industry. Should one or more of these risks or uncertainties occur, or should underlying assumptions prove incorrect, actual results may vary materially and adversely from those anticipated, believed, estimated or otherwise indicated.

Results of Operations

For the quarter ended March 31, 2007, revenue was $1.6 million, compared to $370,000 in the first quarter of 2006, an increase of $1.2 million. We had an operating loss of about $2.3 million in the first quarter of 2007, compared to a loss of $3.1 million in the first quarter of 2006. Non-cash amounts included in the loss for the first quarter is depreciation, depletion and amortization of $252,000; stock compensation expense of $232,000; warrant expense of $273,000 and impairment write-off of $247,000.

Revenues

The Company identifies reportable segments by products and services. The Company includes revenues from both external customers and revenues from transactions with other operating segments in its measure of segment profit or loss. The Company also allocates interest revenue and expense, DD&A, and other operating expenses in its measure of segment profit or loss. The following table sets forth our revenues by segment for the first fiscal quarter of 2007 and 2006, in thousands.

	Three Months Ended March 31, 2007		Three Months Ended March 31, 2006
	$	%	$	%

Total revenues	$1,610	100%	$   364	100%

Oil and Gas

Oil and gas revenues in the first quarter of 2007 included approximately $164,000 from the sale of oil and gas, compared to $319,000 in the first quarter of 2006. The decrease resulted from curtained production from a gas well that needed repair in 2007. Other oil and gas revenues in 2007 consisted of approximately $94,000 from interest income and $34,000 from other income, an increase of $38,000 from the first quarter of 2006 because of maintaining increased cash balances.

The oil and gas activities during the first quarter of 2007 involved the drilling of two wells, reworking of existing wells and the conversion of two wells to commence waterflood operations in the South Belridge field.

The Lundin-Weber D-344-30 was drilled and completed in the South Belridge field. The D-344-30 was a 3/4 mile westerly step-out well on evaluating the Diatomite zone. It was drilled to a total depth of 1929’ and eight cores were taken; three cores in the Tulare zone; three cores in the Etchegoin zone and two cores in the Diatomite zone. These cores will help the Company to better evaluate the best approach to develop this area. The well was completed and fraced in the Diatomite zone and is waiting on a steam generator to stimulate the Diatomite zone via steam. The Lundin-Weber D-188-31 well was drilled 3/4 of a mile south of the D-344-30 well in the South Belridge field. It was drilled to a depth of 1804’. The Company is waiting on the pending results of the D-344-30 well in order to best develop this well.

Nine formerly idle wells were reworked and returned to production in the Belridge-Carneros field. Also in the Belridge-Carneros field, the Company instituted field operations for a waterflood operation in the Etchegoin zone by converting two wells to be used as injectors in two 9-spot programs from existing wells. When complete, the program will consist of two injector wells and 16 producing wells.

The Company has acquired a fleet of steam generators to provide downhole heat and repressure the formations for enhanced recovery. These are being refurbished to meet new environmental regulations before going into service starting in May 2007.

Rig Operations

Revenues from rig operations totaled $1.313 million in the first quarter of 2007, including $1.25 million from drilling and completion operations and approximately $63,000 from other income and interest. This segment of our business was not operating in the first quarter of 2006.

On February 9, GVDC spudded its first contract well in Nevada. It completed its operations in March. At the end of the quarter, GVDC was in talks with multiple third parties for possible long-term contracts for this rig.

In May, Rig #105, a 105-foot high “double” with a 250,000-pound pulling capacity, will be completed and put into production which will increase our total working rigs to three. Two more rigs, Rigs #96A & #96B, are also being remanufactured to be put into the fleet. Upon their completion expected in July and August our total working rigs will be five. Because these rigs all have the newest engines and other improvements including digital controls, they are actually better than when new.

The tactical reason for purchasing the rig fleet is to enable Tri-Valley to work on its growing inventory of wells and drill new ones as needed rather than be delayed for months or even a year because of unavailability of contractor supplied rigs. The strategic reason is that as other property owners experience delays in timely service of their wells and production begins to decline they will tend to want to sell and the only logical bidders will be the few companies like Tri-Valley with the equipment to service additional properties.

Mining Activities

Precious Metals

Revenues from mining activities in the first quarter of 2007 and 2006 were negligible. Mineral programs in the first quarter consisted largely of continued assessment and compilation of the geologic information collected in previous work programs associated with the Richardson and Shorty Creek properties in Alaska, and the design of potential sampling programs for 2007. Select began soliciting large precious metal mining companies as potential joint-venture partners to fund larger scale exploration on both the Richardson and Shorty Creek properties.

Base Metals

Select carried out further reconnaissance work associated with the FARJK claims, a target oxide copper property, located in Nye County, Nevada. Select staked claims associated with the original FARJK claims and conducted a preliminary sampling program on the site.

Select continued its arrangement with Duluth Metals Limited, a Canadian corporation, by providing management and technical assistance to Duluth Metals in its current copper-nickel-PGE drilling program in Northern Minnesota and on other management activities.

Industrial Minerals

During the first quarter, Select carried out a maintenance and repair program at the Admiral Calder calcium carbonate mine in Alaska. Select began soliciting calcium carbonate mining and processing companies as potential joint-venture partners to fund larger scale development and operations on the Admiral Calder mine.

In 2006, Select arranged to evaluate some 200 industrial mineral properties in Nevada from the inventory of Newmont Mining Corporation for future development opportunities. In March 2007, after visiting a number of Newmont's industrial mineral properties and reviewing deal terms with the Trabits Group, the proposed development and operation arrangement between Newmont/Trabits and Select was terminated.

Select also reviewed a number of industrial mineral projects in six western states, covering barite, sand & gravel, aggregate, limestone, dolomite, calcium carbonate, cinder, and other industrial mineral commodities. Some of these projects and opportunities are pending further review.

Drilling and Development Operations

We received no revenues from our drilling and development segment in the first quarter of 2007. This operating segment consists of turnkey contract drilling and completion operations for joint ventures.

Costs and Expenses

The following table sets forth our operating income (loss) by segment in the first quarter of 2007 and 2006, in thousands.

	Quarter Ended 3/31/07	Quarter Ended 3/31/06
Oil and gas	$ (2,230)	$ (1,187)
Rig operations	303	-
Minerals	(330)	(1,977)
Drilling and development	-	-
Total operating income (loss)	$ (2,256)	$ (3,064)

Costs and expenses were approximately $3.86 million more in the first quarter of 2007, an increase of approximately 12% over the same period in 2006 when cost and expenses were $3.43 million. Oil and gas lease expense increased from $57,000 in the first quarter of 2006 to $88,000 in the same period of 2007, as we incurred new expenses to operate the wells we acquired at the end of 2006. Rig operations expense increased from no income in the first quarter of 2006 to $445,000 in the first quarter of 2007, due to new rig operations by our recently formed GVPS and GVDC. We spent $63,000 on mining exploration in the first quarter of 2007, which was $1.1 million dollars less than the same period in 2006. The 2007 expenses were lower mainly because of the disposition in late 2006 of our industrial minerals investment and decreased activity in our minerals operations. Drilling and development expenses increased from $43,000 in the first quarter of 2006 to $232,000 in the first quarter of 2007, reflecting an increase in our drilling activities. Depletion, depreciation and amortization decreased from $275,000 in the first quarter of 2006 to $253,000 in the same period of 2007, because the increased property and equipment from our rig operations was more than offset by the disposition of the Company's interest in its industrial minerals investment in November 2006.

We also recognized impairment losses of $247,000, primarily on the write-off of our ONYX Ranch prospect. During our regular evaluation of our prospects, we determined that this and three other properties are no longer viable.

General and administrative costs more than doubled to $2.5 million in the first quarter in 2007 compared to $1.2 million in the first quarter of 2006, due primarily to the expenses of our recently formed drilling subsidiaries.

Capital Resources and Liquidity

In 2002 through the first quarter of 2007, our drilling activities have been largely funded by selling interests in our OPUS I drilling partnership. We do not borrow in order to fund drilling activities. Our continued drilling activity relies on our ability to raise money for projects through drilling partnerships or other joint ventures.

Current assets were about $20.7 million at March 31, 2007, up from $16.0 million at year end 2006. Cash on hand was increased from $15.6 million at year end 2006 to $19.7 million at March 31, 2007. The increase in cash was due to private placements of stock.

Current liabilities rose to about $10.9 million at March 31, 2007, from $9.0 million at year end 2006, due primarily to an increase of $1.1 million in accounts payable and an increase of about $1.5 million in advances from joint venture participants.

Operating Activities

We had a positive cash flow of $49,604 for the three months ended March 31, 2007 compared to a negative cash flow of $1,165,769 for the same period in 2006, the positive cash flow in the current period is due mainly to our loss from operations being offset by our increase in advances from joint venture participants. Our loss from operations was approximately $2.3 million for the three months ended March 31, 2007 compared to a $3.1 million loss for the same period in 2006.

The largest component of positive cash flow in the first quarter of 2007 was receipt of advances of more than $1.4 million from joint venture participants for future drilling operations, which exceeded advances received in the first quarter of 2006 by $1.3 million. These do not contribute to operating revenues at the time received but are held in cash until expended in drilling and operations. We cannot predict the levels at which we will continue to receive funds for additional drilling, and in the past we have experienced wide swings in receipt of these funds from quarter to quarter. We do not commit to drilling activities unless and until we have sufficient advances in hand to fund a particular project.

Investing Activities

Cash used in investing activities was $1.1 million for the first three months of 2007. Most of this was used towards the refurbishing of the new rigs for GVPS and the reminder was for the acquisitions of equipment for TVOG.

Financing Activities

Net cash provided by financing activities was $5.1 million for the first quarter. We received $5.6 million from sales of restricted shares of common stock in privately negotiated transactions including the exercise of stock options by employees. We used $395,000 to buy back membership units in GVDC and GVPS. We used $45,000 to pay down principal on long-term debt. We received $458,000 in proceeds from warrants issued in conjunction with the issuance of restricted shares of common stock in privately negotiated transactions which had warrants attached and had stock issuance costs of $706,000. We expect to use these funds for working capital. We have not planned any private placement of equity securities for the remainder of 2007, but we may continue to receive funds from privately negotiated transactions. We do not have a targeted or budgeted amount of equity financing activities.

Liquidity

During the remainder of 2007, we expect to expend approximately $25 million on drilling activities. Funds for these activities will be provided by sales of partnership interests in the Opus I drilling partnership, which will still be raising funds for development purposes. Tri-Valley’s portion is expected to be approximately $6 million. We are analyzing results of four recent development test wells on our Temblor West producing property adjoining the South Belridge oil field in order to design the optimum development plan for the property and have began work on a fifth well. We expect to drill several wells there in 2007. Also, at our Pleasant Valley property in the Oxnard oilfield we project one vertical development test well, one horizontal injector and one horizontal producer in 2007. We will drill at least one shallow well in the Moffat Ranch East gas field and one deep wildcat exploration well for an aggregate expenditure in the range of $25 million for the remainder of the year. Tri-Valley’s share will be in the range of $6 million as most of the expense will be carried by joint venture partners. Our ability to complete our planned drilling activities in 2007 depends on some factors beyond our control, such as availability of equipment and personnel. Our actual capital commitments for the remainder of fiscal year 2007 are less than $3 million, but to expend $25 million we will require additional capital from the OPUS partnership or other outside parties. For the remainder of fiscal year 2007, we expect expenditures of approximately $ 1.3 million on mining activities, including mining lease and exploration expenses.

See Note 3 to our unaudited consolidated financial statements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Tri-Valley Corporation does not engage in hedging activities and does not use commodity futures or forward contracts in its cash management functions.

Item 4. Controls and Procedures

Disclosure Controls

As of March 31, 2007, an evaluation was performed under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. These controls and procedures are based on the definition of disclosure controls and procedures in Rule 13a-15(e) and Rule 15d-15(e) promulgated under the Securities Exchange Act of 1934. Based on that evaluation, our management, including the CEO and CFO concluded that our disclosure controls and procedures were not effective as of March 31, 2007. Management identified internal control deficiencies, which, in management’s judgment, represented material weaknesses in internal control over financial reporting. The control deficiencies generally related to controls over the accounting for complex transactions to ensure such transactions are recorded as necessary to permit preparation of financial statements and disclosures in accordance with generally accepted accounting principles and were first discovered by our independent auditors during their audit of our consolidated financial statements for the year ended December 31, 2006. Such transactions included:

o   Proved and unproved properties

o   Deferred income taxes;

Management has remediated three of the five material weaknesses identified in the Company’s Annual Report on Form 10-K for the year ended 2006. The weaknesses were remediated by instituting improved procedures, additional controls regarding collateralized loans and improved disclosure of share-based payment arrangements.  The remediated weaknesses are;: Loans guaranteed with restricted common stock (deposits); the accounting treatment for the discontinued operations from the sale of our interest in Tri Western Resources; and share-based payment arrangements. To remediate the remaining two control deficiencies in our disclosure controls and our internal control over financial reporting. Management plans to:

o   Complete a review, update and risk assessment of all of our financial controls and procedures;

o   Provide additional training of financial staff;

o   Purchase additional research materials and services; and

o   Shorten the financial closing process to allow more time for a thorough review

o   Improve the reporting disclosure and the formulation of deferred taxes

Management, including our CEO and CFO, do not expect that our disclosure controls and procedures or internal control over financial reporting will prevent all errors and fraud. In designing and evaluating our control system, management recognized that any control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired control objectives. Further, the design of a control system must reflect the fact that there are resource constraints, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any that may affect our operations have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake.

During the first quarter of 2007, there were no changes in the Company's internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
