TRI-VALLEY CORPORATION

NOTES TO CONDENSED FINANCIAL STATEMENTS

FOR THE NINE MONTHS ENDED

SEPTEMBER 30, 2001 AND 2000

(Unaudited)

NOTE 1 - 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 nine-month period ended September 30, 2001, 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; and, therefore, should be read in conjunction with the Company's Annual Report on Form 10-KSB for the year ended December 31, 2000.







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 - RECENT ACCOUNTING PRONOUNCEMENTS

In July 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible Assets." This standard becomes effective for fiscal years beginning after December 15, 2001. Beginning in the first quarter of fiscal 2002, goodwill will no longer be amortized but will be subject to annual impairment tests. All other intangible assets will continue to be amortized over their estimated useful lives. Goodwill existing at September 30, 2001 will continue to be amortized through the end of fiscal 2001. Through the end of fiscal 2001, the company will test goodwill for impairment using the current method, which uses an undiscounted cash flow test.

Business Review

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 the Company'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.

Petroleum Activities

For the nine months ended September 30, 2001, we have continued to evaluate the Ekho No. 1 with the assistance of a team of experts. We currently are in the process of finding interested parties to invest in the project to hopefully bring it into completed, producing status.

We continue to endeavor to bring the appropriate parties into the Sunrise Natural Gas Project. Our efforts will require one or more horizontal wells to be drilled. We anticipate initially four wells will be drilled to determine the aerial extent of the project. Ultimately this project could require as many as forty wells for full development.

We are planning on drilling at least one well in our Sonata gas prospect this year, which is west of the Sunrise Project Area. With the Sunrise and Sonata projects, Tri-Valley has over 12,000 acres in the middle of the McClure Shale.

Natural gas prices began the year at historic highs but have more recently fallen. We sold gas for as much as $14.64 per Mcf early in the year, but in the third quarter we also sold for as low as $2.71. We believe that natural gas prices will continue to be volatile (especially in California) for the remainder of 2001 and possibly for years.

Precious Metals

The Russian scientists from TsNIGRI, the Russian Mineral Institute in Moscow began this years' activity for Tri-Valley the latter part of July. Our efforts continue to obtain sufficient data to enable a joint venture with a major mining company for exploration of our Alaska claims, similar to the Placer Dome arrangement of the previous two years that ended at the end of 2000. Placer

Dome withdrew from the joint venture primarily due to the continued low price for gold, which led to a reduction in most exploratory project worldwide by almost all large mining companies.

Three Months Ended Sept. 30, 2001 as compared with Three Months ended Sept. 30, 2000

In the quarter ended September 30, 2001, total revenue decreased $65,607 compared to the same quarter in the year 2000. This decrease was due to a reduction in natural gas sales in the period ending September 30, 2001. We had oil and gas sales of $231,055 in the third quarter of 2000 compared to $177,904 for the same period in 2001 a reduction of $53,151. Other income was $13,187 higher this period compared to the same period in 2000. Interest income was $25,643 less for this period versus the same period in 2000 because we had less funds on deposit in interest bearing accounts, awaiting expenditures on drilling and completion of wells.

Costs and expenses decreased to $470,732 for the quarter ending September 30, 2001 from $532,560 for the same period in 2000. Oil and gas lease expenses were $23,386 higher in the period ending September 30, 2001, due to work over expenses on the Hanson wells. Geologic, geophysical, land and administration costs were $20,531 less this period compared to the same period in 2000. General and Administrative costs were $53,460 less for this quarter compared to the same period last year due to reduced legal expenses related to a lawsuit that ended in 2000.

We had a loss of $172,172 for the three months ended September 30, 2001, compared to a loss of $168,393 for the same period in 2000.

Nine Months Ended Sept. 30, 2001 as compared to September 30, 2000

We had total revenue of $1,662,516 for the nine months ended September 30, 2001 compared to revenue of $2,174,390 for the same period in 2000. Revenue for the period in 2000 included revenue from the sale of the Sunrise Prospect in 2000; we have not had a corresponding sale in 2001. For the nine months ended September 30, 2001, we had a 254% increase in oil and gas sales due to increased natural gas prices for the nine months ended September 30, 2001, compared to the same period in 2000. Other income was $1,341,398 less for the nine months ended September 30, 2001, compared to the same period last year. This decrease is due to revenue received in 2000 for the sale of a prospect. We have not sold any prospects in 2001. Interest income was down $52,003 for the current year to date nine months because we had less funds on deposit in interest bearing accounts, awaiting expenditures on drilling and completion of wells.

Costs and expenses were $1,518,228 in the period ending September 30, 2001 compared to $2,036,495 for the same period in 2000. Oil and gas lease expenses were up for the first nine months due to the Company doing re-works of several of its wells. Project geology, geophysics, land and administration were $139,900 less this year due to costs in 200 related to the Sunrise Project. Cost of sale of assets is $394,240 less this period compared to the same period in 2000 due to the sale of the Sunrise prospect in 2000. Interest expense is $9,135 less this period ending September 30, 2001,

compared to the same period in 2000. General and Administrative costs were $166,571 less due to reduced legal expenses related to the lawsuit.

Net income, for the nine months ended September 30, 2001, is $144,288 compared to $137,895 for the same period in 2000.

Capital Resources and Liquidity

We had current assets at September 30, 2001, of $814,037 compared to $2,203,960 for the period ending December 31,2000. This decrease was due to reduction of cash and reduction in accounts receivable. Current liabilities were $2,680,069 for the period ended September 30, 2001, compared to $3,649,568 for the year ending December 31, 2000. This reduction was due to a reduction in accounts payable and reduction in advances from joint venture participants.

Operating Activities. Cash provided by operations were deficit of $98,809 for the nine months ended September 30, 2001 compared to a deficit of $5,531,229 for the same period in 2000. This was due to reduced expenditures of the drilling operations for the Sunrise well. The $389,169 decrease in advances from joint venture participants at September 30, 2001, is due to the expenditure of funds used for the drilling activity on the Sunrise Project and Project Ekho.

Financing Activities. Net cash provided by financing activities decreased $197,615 for the period ended September 30, 2001, over the same period in 2000 due to the reduced amount of sales of the Company's common stock in private transactions.

Investing Activities. For the nine months ended September 30, 20001 we spent $652,738 to lease oil and gas acreage for prospect generation and to enable the to put drilling programs together. We expect to recoup these amounts as the drilling prospects are sold.
