Because it is a summary, it does not contain all the information that you should consider before making a decision as to whether to tender your old notes in this exchange offer. You should read this entire prospectus carefully before making a decision. Unless the context requires otherwise, references in this prospectus to "Tri-Union," "we," "us" and "our" refer to Tri-Union Development Corporation and Tri-Union Operating Company, our wholly-owned subsidiary. The consolidated historical financial, reserve, operating and pro forma data set forth in this prospectus include information for our subsidiary and us on a consolidated basis. The information in this prospectus gives effect to our merger with our former parent corporation, Tribo Petroleum Corporation, on July 27, 2001. If you are not familiar with some of the oil and natural gas terms used in this prospectus, please read "Glossary of Oil and Natural Gas Terms" beginning on page 127. OUR COMPANY We are an independent oil and natural gas company engaged in the acquisition, development, exploration and production of oil and natural gas properties in three core areas. Our core areas are located onshore Gulf Coast, primarily in Texas and Louisiana, offshore Gulf Coast in the shallow waters of the Gulf of Mexico and in the Sacramento Basin of northern California. We have established significant operating expertise in our core areas which we believe allows us to better anticipate and manage operating expenses, produce our properties more efficiently and improve recovery from our reservoirs. We have one subsidiary, Tri-Union Operating Company, which is wholly owned by us. Tri-Union Operating's principal asset is a net profits interest in a field operated by us. This interest is the only oil and natural gas property of Tri-Union Operating and represents less than 5% of our consolidated proved reserves. At December 31, 2000, we had net proved reserves of 180.1 Bcfe, approximately one-half of which were natural gas, with a reserve life of 11.0 years. Our reserve base is diversified across our three core areas, with 64% of our proved reserves located onshore Gulf Coast, 12% offshore Gulf Coast and 24% in California. Each of these core areas is characterized by years of stable, historical production and numerous producing wells. We operate approximately 92% of our proved reserves. We have a large inventory of development projects that we have only recently begun to exploit. Because we operate in older, more mature fields with long production histories and many producing wells, we believe these projects represent low-risk opportunities to add to our reserves. We completed 28 of these projects during 1999 and 2000 for $10.6 million in development capital expenditures for drilling and recompletions, resulting in a 42% increase in our daily production. We experienced a 75% drilling success rate over that period. We have identified another 175 similar projects on our existing fields to pursue through 2003. Of these projects, 116 are proved behind pipe and proved undeveloped projects and two are 3-D seismic surveys in California. We have allocated $14.9 million of our capital budget for the second half of 2001, $19.3 million for 2002 and $3.5 million for 2003 for these projects. The balance of 57 projects are behind pipe opportunities in the Sacramento Basin that were not classified as proved at December 31, 2000. Of these projects, 24 and 33 may be added to our budgeted projects during 2001 and 2002, respectively, depending on our capital resources. We anticipate that we may expend an additional $720,000 during the remainder of 2001 and $990,000 in 2002 should we decide to fund these projects. Further, depending on our capital resources, we may substitute some of these projects for currently budgeted projects as these behind pipe opportunities are less expensive than many of our budgeted development projects. Approximately 80% of our projected oil and natural gas production from proved developed producing reserves (and the basis differential attributable to approximately 80% of our projected proved developed producing natural gas production from our California properties) is hedged through June 30, 2003 at swap prices of $4.19 per Mcf and $25.30 per Bbl, or a weighted-average natural 1 gas-equivalent price of approximately $4.20 per Mcfe. In connection with the original offering, we agreed to maintain, on a monthly basis, a rolling two-year hedge program until the maturity of the old notes and the new notes, subject to certain conditions. We believe this hedging program will provide us with the financial capacity to successfully execute our development plans and profitably grow production from current levels. Our principal executive offices are located at 530 Lovett Boulevard, Houston, Texas 77006-4021, and our telephone number is (713) 533-4000. OUR BANKRUPTCY AND RECAPITALIZATION In March 1998, we acquired certain onshore Texas oil and natural gas properties from Apache Corporation. Prior to the acquisition, we had approximately $35 million in debt outstanding. We incurred approximately another $63 million in debt in connection with the acquisition of these properties from Apache. A portion of this debt was in the form of a short-term, amortizing bank loan. In August 1998, before we were able to refinance our bank loan, commodity prices began falling, with oil prices ultimately reaching a 12-year low in December 1998. The resultant negative effect on our cash flow from the deterioration of commodity prices, coupled with the required amortization payments on our bank loan, severely restricted the amount of capital we were able to dedicate to development drilling. Consequently, our oil and natural gas production declined, further negatively affecting our cash flow. In October 1998, our short-term loan matured and we arranged a forbearance agreement providing for interest payments to be partially capitalized and providing us with additional time to refinance our obligations. In July 1999, the forbearance agreement terminated and we made negotiated interest payments while attempting to negotiate a restructuring of our obligations. By March 2000, the aggregate principal balance of our bank debt had increased as a result of capitalized interest and expense to approximately $105 million. In February 2000, the bank declared a default on the loan, demanded payment of all principle and interest and posted the shares of Tribo Petroleum Corporation, our parent corporation and a guarantor of the loan, for foreclosure. As a consequence of the banks's foreclosure action, on March 14, 2000, we chose to seek protection under Chapter 11 of the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the Southern District of Texas, Houston Division. Tri-Union Operating continued to operate outside of bankruptcy. As a result of the redeployment of funds formerly utilized for amortization payments, we have conducted a limited but highly successful, low-risk development drilling program, which has resulted in an increase of approximately 42% in our average daily production over the last two years. This production increase, coupled with improved commodity prices, allowed us to increase our cash position to approximately $66.7 million immediately prior to closing of the original offering on June 18, 2001, from approximately $1.4 million on March 14, 2000. The original offering was a private unit offering, with each unit consisting of one old note in the principal amount of $1,000 and one share of class A common stock of our former parent corporation, Tribo Petroleum Corporation, with which we merged on July 27, 2001. The units were sold to Jefferies & Company, Inc., as initial purchaser, which then resold the units to qualified institutional buyers in reliance on Rule 144A under the Securities Act. The proceeds of the original offering and our available cash balances at closing were sufficient to allow us to pay or segregate funds for the payment of all creditor claims in full, including interest, and to exit bankruptcy on June 18, 2001. The old notes are our only material long-term indebtedness. Our level of indebtedness as of June 30, 2001, was $130.0 million as compared to adjusted EBITDA on a pro forma basis for the six months then ended of $36.8 million and for the year ended December 31, 2000, of $42.0 million. Our significant leverage creates risks for holders of the notes, including the risk that we will be unable to satisfy the amortization payments due on the notes on June 1, 2002, 2003 and 2004. 2 THE EXCHANGE OFFER Securities Offered.................. We are offering to exchange old notes for new notes in the aggregate principal amount of up to $130,000,000. The new notes will evidence the same debt as the old notes and will be entitled to the benefits of the same indenture as the old notes. The terms of the new notes and the old notes are substantially identical, except that the new notes will not generally be subject to the transfer restrictions nor have the registration rights applicable to the old notes. The Exchange Offer.................. The new notes are being offered in exchange for a like principal amount of the old notes. The old notes may be exchanged only in integral multiples of $1,000. Expiration Date..................... The exchange offer expires at 5:00 p.m., New York City time, on , 2001, or such later date and time to which it is extended by us in our sole discretion. Withdrawal Rights................... Tenders may be withdrawn at any time prior to the expiration date. Any old notes not accepted for any reason will be returned without expense to the tendering holder thereof as promptly as practicable after the expiration or termination of the exchange offer. Effect of Exchange on Holder of New Notes............................... Based on interpretations by the staff of the SEC as set forth in no-action letters issued to third parties we believe that the new notes issued in exchange for old notes may be offered for resale, resold or otherwise transferred by holders (other than any holder which is an "affiliate" of ours within the meaning of Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such new notes are acquired in the ordinary course of the holder's business and the holder has no arrangement with any person to participate in the distribution of such new notes. In addition, holders of new notes will have no further registration rights under the registration rights agreement. Effect of Failure to Exchange on Holders of Old Notes................ All untendered, and tendered but unaccepted, old notes will continue to be subject to the restrictions on transfer provided for in the old notes and the indenture. To the extent old notes are tendered and accepted in the exchange offer, the trading market, if any, for the old notes could be adversely affected. Holders of the old notes that do not exchange their old notes for new notes will, after 3 the exchange is consummated, have no further registration or other rights under the registration rights agreement. Holders of the old notes will continue to be entitled to all the rights and limitations under the indenture. Procedure for Tendering Old Notes... For you to validly tender old notes in the exchange offer, either: - a properly completed and duly executed letter of transmittal, or a manually executed facsimile of that document, along with any required signature guarantees, or an agent's message in connection with a book-entry transfer, and any other required documents, must be transmitted to and received by the exchange agent at its address set forth on page 29 of this prospectus under the heading "The Exchange Offer -- Exchange Agent" and certificates for tendered old notes must be received by the exchange agent at one of those addresses, or those old notes must be tendered in accordance with the procedure for book-entry tender (and a confirmation of receipt of the tender received), in each case before the expiration date. See "The Exchange Offer -- Exchange Offer Procedures -- General", "-- Book-Entry Transfer" and "-- Certificated Old Notes" beginning on page 24 for more details; or - you must comply with the guaranteed delivery procedures set forth in "The Exchange Offer -- Guaranteed Delivery Procedures" beginning on page 26. Use of Proceeds..................... We will not receive any cash proceeds from the issuance of new notes. Exchange Agent...................... Firstar Bank, National Association is serving as the exchange agent in connection with the exchange offer. United States Federal Income Tax Consequences...................... The exchange of old notes should not be a taxable event for United States federal income tax purposes. 4 THE TERMS OF THE OLD NOTES AND THE NEW NOTES Issuer.............................. Tri-Union Development Corporation. Maturity Date....................... June 1, 2006. Amortization Payments............... On June 1, 2002, 2003 and 2004, we will make amortization payments of the greater of $20.0 million and 15.3%, $20.0 million and 15.3%, and $15.0 million and 11.5%, respectively, of the aggregate principal amount of the notes, reduced by any amortization payments made prior to the payment date, together with accrued and unpaid interest to the date of payment. Interest Rate and Payment Dates..... The notes bear interest at a rate of 12.5% per annum. Interest on the new notes will accrue from the last date on which interest was paid on the old notes surrendered in exchange for the new notes or, if no interest has been paid, from the date of original issuance of the old notes. Interest will be payable semi-annually in cash in arrears on June 1 and December 1 of each year, commencing December 1, 2001. Collateral and Intercreditor Rights.............................. The notes and the guarantees by our subsidiary and any future subsidiaries will be secured by a first lien on substantially all existing and future oil and natural gas properties owned by us and our subsidiary. The notes are subject to certain payment priorities in connection with commodity hedge agreements we entered into in connection with the issuance of the old notes, and the collateral securing the notes will be subject to certain permitted liens. Guarantees.......................... The notes will be unconditionally guaranteed on a senior secured basis by Tri-Union Operating Company, as well as all of our future subsidiaries. The guarantees will rank senior in right of payment to all unsecured senior indebtedness of the guarantors, to the extent of the value of the pledged collateral. The guarantees will be subject to certain payment priorities in connection with commodity hedge agreements that we entered into in connection with the issuance of the notes and that we will be required to enter into the future under the terms of the indenture, and the collateral securing the guarantees will be subject to certain permitted liens. Ranking............................. The notes will rank senior in right of payment to all of our unsecured senior indebtedness, to the extent of the value of the pledged collateral. Original Issue Discount............. The old notes were issued with, and the new notes will be deemed to have been issued with, 5 original issue discount for federal income tax purposes. You should be aware that accrued original issue discount will be included periodically in your gross income for federal income tax purposes. See "Material United States Federal Tax Considerations -- Notes" beginning on page 121 for more details. Optional Redemption................. The notes will be redeemable at our option, in whole or in part, at any time on or after June 1, 2004, at redemption prices equal to 104% of the aggregate principal amount of the notes to be redeemed, or 100% of the aggregate principal amount of the notes to be redeemed on or after June 1, 2005, in each case together with accrued and unpaid interest to the date of redemption. In addition, in the event we consummate a public equity offering prior to June 1, 2003, we may use all or a portion of the net proceeds from that offering to redeem up to 30% of the aggregate principal amount of the notes at a redemption price equal to 112.5% of the principal amount of the notes to be redeemed, together with accrued and unpaid interest to the date of redemption. The redemptions from a public equity offering will be limited so that no less than 70% of the aggregate principal amount of the notes will remain outstanding. Repurchase Obligations Upon Change of Control.......................... Upon a change of control, each holder of notes will have the right to require us to repurchase all or a portion of such holder's notes at a repurchase price equal to 101% of the principal amount of the notes, together with accrued and unpaid interest to the date of repurchase. Certain Covenants................... The new notes will be issued under the same indenture as the old notes. The indenture contains certain covenants including, but not limited to, covenants that limit our ability to: - incur additional indebtedness and issue disqualified capital stock; - pay dividends; - make certain restricted payments; - consummate certain asset sales and asset sale offers; - enter into certain transactions with affiliates; - incur liens; 6 - merge or consolidate with any other person or sell or otherwise dispose of all of our assets; - sell or issue capital stock of a restricted subsidiary; - enter into new lines of business; and - enter into synthetic lease transactions. The indenture also contains covenants regarding the designation of unrestricted subsidiaries, ownership of restricted subsidiaries, issuance of reports, liens on additional collateral and the independence of our board of directors. Hedge Covenant...................... Approximately 80% of our projected oil and natural gas production from proved developed producing reserves (and the basis differential attributable to approximately 80% of our projected proved developed producing natural gas production from our California properties) is hedged through June 30, 2003 at swap prices of $4.19 per Mcf and $25.30 per Bbl, or a weighted-average natural gas-equivalent price of approximately $4.20 per Mcfe. In connection with the original offering, we agreed to maintain, on a monthly basis, a rolling two-year hedge program until the maturity of the old notes and the new notes, subject to certain conditions. Excess Cash Flow Offer.............. If we have excess cash flow of at least $1.0 million during any fiscal quarter beginning with the quarter ended June 30, 2004, we will be obligated to purchase notes at 100% of the principal amount thereof, plus accrued and unpaid interest, provided that the amount required to be paid to repurchase notes will be limited to the amount of 50% of such excess cash flow. RISK FACTORS Before deciding to invest in the notes or to tender your old notes in exchange for the new notes, you should carefully consider the information included in "Risk Factors" beginning on page 11, as well as all other information set forth in this prospectus. 7 SUMMARY HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA The following table sets forth some of our historical and pro forma consolidated financial data. You should read the following data in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations," the pro forma financial data and the consolidated financial statements and related notes included in this prospectus. The summary financial and other data as of, and for the years ended December 31, 1998, 1999 and 2000, have been derived from the audited consolidated financial statements included in this prospectus.

Fixed charges represent interest expense and capitalized interest (including amortization of deferred finance charges and an estimated portion of rentals representing interest costs). Earnings to fixed charges were 2.18x and 1.44x for the years ended December 31, 1996 and 1997, respectively. Earnings were insufficient to cover fixed charges by $15.8 million, $9.2 million, $5.7 and $20.8 million for the years ended December 31, 1998, 1999, 2000 and on a pro forma basis for the year ended December 31, 2000, respectively. NM means "not measured." (2) EBITDA means earnings before interest expense, income taxes, depreciation, depletion and amortization. Adjusted EBITDA means EBITDA before impairment of oil and natural gas properties, reorganization costs, and gains or losses on derivative contracts. EBITDA is commonly used by debt holders and financial statement users as a measurement to determine the ability of an entity to meet its interest obligations. EBITDA is not a measurement presented in accordance with generally accepted accounting principles ("GAAP") and is not intended to be used in lieu of GAAP presentation of results of operations and cash provided by operating activities. Our definition of adjusted EBITDA may not be identical to similarly entitled measures used by other companies. (3) Cash interest excludes non-cash interest for amortization of bond discount and bond issuance costs, which are included in determining interest expense in accordance with GAAP. (4) ACNTA means Adjusted Consolidated Net Tangible Assets, as defined in "Description of the Senior Secured Notes -- Certain Definitions" beginning on page 96. ACNTA is calculated using oil and natural gas prices utilized in our year end reserve report. 9 SUMMARY HISTORICAL RESERVE DATA The following table sets forth summary information with respect to our estimated net proved oil and natural gas reserves as of the periods shown. Please read "Risk Factors -- Our estimates of oil and natural gas reserves and future net revenue are uncertain and inherently imprecise", beginning on page 15, regarding the risks of relying upon the information in the table. <Table> <Caption> AT DECEMBER 31, ------------------------------ 1998 1999 2000 -------- -------- -------- Proved reserves: Oil and condensate (MBbls)............................... 11,319 15,851 15,073 Natural gas (MMcf)....................................... 111,149 110,092 89,699 Total (MMcfe).................................... 179,063 205,198 180,137 Proved developed reserves: Oil and condensate (MBbls)............................... 9,124 12,957 12,290 Natural gas (MMcf)....................................... 58,088 58,265 45,575 Total (MMcfe).................................... 112,832 136,007 119,315 PV-10 Value (in thousands)(1).............................. $118,151 $292,495 $630,002 Standardized Measure (in thousands)(2)..................... $105,403 $231,564 $472,279 Reserve life (in years).................................... 13.9 14.8 11.0 </Table> --------------- (1) The average prices used in calculating PV-10 Value as of December 31, 2000 were $10.31 per Mcf and $25.90 per Bbl.

Please read "Management's Discussion and Analysis of Financial Condition and Results of Operations" beginning on page 38. 10 RISK FACTORS The exchange and ownership of notes involves a high degree of risk. You should carefully consider the risks described below and the other information in this prospectus before deciding to invest in the notes or to exchange old notes for new notes. RISKS RELATING TO THE EXCHANGE OFFER Broker-dealers or certain holders may become subject to the registration and prospectus delivery requirements of the Securities Act. Holders that are our "affiliates" within the meaning of Rule 405 under the Securities Act and holders that have not acquired new notes in the ordinary course of such holder's business or who have an arrangement with any person to participate in the distribution of new notes will not be able to offer for resale, resell or otherwise transfer new notes without first complying with the registration and prospectus delivery provisions of the Securities Act. Further, while we believe other holders may be able to offer for resale, resell or otherwise transfer new notes without complying with the provisions of the Securities Act, our belief is based upon interpretations of no-action letters issued to third parties and we have not requested the SEC to issue, and the SEC has not issued, a no-action letter with regard to the exchange offer. Each broker-dealer that receives new notes for its own account pursuant to the exchange offer must deliver a prospectus in connection with any resale of such new notes. In addition, to comply with the securities laws of certain jurisdictions, the new notes may not be offered or sold unless they have been registered or qualified for sale in such jurisdiction or an exemption from registration or qualification is available and is complied with. We have agreed to register or qualify the new notes for offer or sale under the securities or blue sky laws of such states as any holder of the new notes reasonably requests in writing but our obligation to do so is limited to jurisdictions within the United States and where we are not required to qualify generally to do business or subject ourselves to taxation in any jurisdiction where we are not otherwise qualified or subject to taxation. RISKS RELATING TO THE OLD NOTES AND THE NEW NOTES The value of the pledged collateral securing the notes may be inadequate, and there are risks that may reduce your ability to conduct a successful foreclosure. We have granted a first lien on, and have pledged to the holders of the notes, substantially all of our proved oil and natural gas properties and our hedge contracts. However, you may be unable to foreclose on or dispose of any of the collateral without substantial delays and other risks. For example, the ability of the trustee for the holders of the notes to realize upon the collateral will be subject to certain procedural limitations as further described in this prospectus under "Description of the Senior Secured Notes -- Defaults," beginning on page 88, and "Possession, Use and Release of Collateral -- Release" beginning on page 91. In addition, if we become a debtor in a new case under the Bankruptcy Code, the automatic stay imposed by the Bankruptcy Code would prevent the trustee from selling or otherwise disposing of the collateral without the bankruptcy court's authorization. In that case, the foreclosure might be delayed indefinitely. Further, the proceeds obtained from a foreclosure may be insufficient to pay all amounts owing to holders of the notes and the approved hedge counterparties, others who have a payment priority under the intercreditor agreement and amounts due to holders of permitted liens. At December 31, 2000, we had oil and natural gas properties with a PV-10 Value of $630.0 million. The average prices used in calculating PV-10 Value as of December 31, 2000 were $10.31 per Mcf and $25.90 per Bbl. Assuming benchmark prices of $4.25 per Mcf and $25.00 per Bbl (or net realized prices of $4.82 per Mcf and $24.10 per Bbl), our PV-10 Value would have been $309.3 million at December 31, 2000. The reserve data with respect to such interests, however, represent estimates only and should not be construed as exact. Moreover, the estimated PV-10 Value should not be construed as the current 11 market value of the estimated proved reserves attributable to our oil and natural gas properties. Please read "-- Our estimates of oil and natural gas reserves and future net revenue are uncertain and inherently imprecise" beginning on page 15. In addition, the terms of the indenture allow us to issue additional notes provided that we meet certain financial tests. Please read "Description of the Senior Secured Notes -- Certain Covenants -- Limitation on Indebtedness" beginning on page 76. The indenture does not require that we maintain the current level of collateral or maintain a specific ratio of indebtedness to asset values. Any additional notes issued pursuant to the indenture will rank equal to the notes and will be entitled to the same rights and priority with respect to the collateral. Thus, the issuance of additional notes pursuant to the indenture may have the effect of significantly diluting the trustee's ability to recover payment in full from the then existing pool of collateral. Please read "Description of the Senior Secured Notes" beginning on page 71. You will be required to include original issue discount in ordinary income for federal income tax purposes. The notes have original issue discount. You will be required to include original issue discount in ordinary income for federal income tax purposes as it accrues before you receive cash payments attributable to such income, regardless of your method of accounting. If a bankruptcy case is commenced by or against us after the issuance of the notes, the claim of a holder of the notes may be limited to an amount equal to the sum of: - the initial offering price allocable to the notes; plus - stated interest and original issue discount that has accrued on the notes as of the date of any bankruptcy filing; less - any payments made on the notes before the bankruptcy filing. Our principal stockholder owns approximately 65% of our class A common stock, representing 55% of our total common stock outstanding, which may prevent new investors from influencing corporate decisions. Richard Bowman, our principal stockholder and Chief Executive Officer, owns approximately 65% of our class A common stock, which represents 55% of our total common stock outstanding. As a consequence, Mr. Bowman is able to affect the outcome of all matters requiring stockholder approval, including the approval of significant corporate transactions, such as transactions involving a change of control. The interests of Mr. Bowman may differ from yours, and Mr. Bowman may vote his class A common stock in a manner that may adversely affect you. Jefferies & Company, Inc. owns all of our class B common stock, representing approximately 15% of our total common stock outstanding, and will have special class voting and other rights in connection with such ownership. Jefferies & Company, Inc. owns all of the outstanding shares of our class B common stock, which votes as a separate class on all matters subject to a stockholder vote. By voting as a separate class, Jefferies is able to affect the outcome of all matters submitted to a stockholder approval. Additionally, Jefferies will be entitled to elect one member to serve as a non-voting advisory director to our board of directors and to cause us, at any time, to increase the size of our board of directors and to immediately elect a majority of the directors. These additional rights will allow Jefferies to exercise control over our management and operations at any time. The interests of Jefferies may differ from yours, and Jefferies may exercise its voting and other special rights in a manner that may adversely affect you. The class voting and other special rights of Jefferies will terminate under certain circumstances, including at the election of Jefferies. 12 There is currently no public market for the notes, and there may never be a public market for the notes. There is currently no public market for the old notes or the new notes. We do not intend to list the old notes or the new notes on any national securities exchange or to seek the admission thereof to trading over the National Association of Securities Dealers Automated Quotation System. The old notes currently are eligible for trading by qualified institutional buyers in the PORTAL market. Trading in the notes may not develop or may be sporadic, limiting the ability of holders of the notes to sell their notes. To the extent trading does occur, volumes may be limited and prices may be volatile as a consequence of this and other factors, many of which are beyond our control, including: - changes in oil and natural gas prices; - actual or anticipated variations in quarterly operating results; and, - additions or departures of key personnel. Debt covenants may limit our future flexibility in obtaining additional financing and in pursuing business opportunities. Covenants in the notes will require us to meet certain financial tests in order to incur additional indebtedness. Failing to comply with such tests and incurring additional indebtedness could cause an event of default under the terms of the indenture. If we are unable to borrow additional money or obtain additional financing, our ability to successfully operate and service our debt obligations could be hindered and we may not be able to make scheduled debt payments of principal and interest to the holders of the notes. Please read "-- Our significant leverage and lack of capital resources may affect our ability to successfully operate and service our debt obligations" beginning on page 14. The guarantee by our subsidiary and any guarantees by future subsidiaries could be deemed fraudulent conveyances under certain circumstances, and a court may subordinate or void the subsidiary guarantees. Various fraudulent conveyance laws could be utilized by a court to subordinate or avoid the guarantee by our subsidiary and any guarantees by future subsidiaries. It is also possible that under certain circumstances a court could hold that the direct obligations of the guarantor could be superior to the obligations under the guarantee of the notes. Generally, to the extent that a court were to find that at the time a guarantee was entered into either: - the guarantee was incurred with the intent to hinder, delay or defraud any present or future creditor or that our subsidiary contemplated insolvency and intended to favor one or more creditors to the exclusion in whole or in part of others; - our subsidiary did not receive fair consideration or reasonably equivalent value for issuing the guarantee; - our subsidiary was insolvent or rendered insolvent by reason of the issuance of the guarantee; - our subsidiary was engaged or about to engage in a business or transaction for which its remaining assets constituted unreasonably small capital; or - our subsidiary intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they matured; 13 then the court could, among other things, avoid all or a portion of the guarantee, or subordinate the guarantee to other existing and future debt of our subsidiary. The result would be to entitle other creditors to be paid in full before any payment could be made on the guarantee. Among other things, a legal challenge to the guarantee might focus on the benefits, if any, realized by our subsidiary as a result of the issuance by us of the notes. To the extent the guarantee is avoided as a fraudulent conveyance or held unenforceable for any other reason, you would cease to have any claim against our subsidiary and would be a creditor solely of us. RISKS RELATING TO OUR BUSINESS, FINANCES AND OPERATIONS Our bankruptcy may adversely affect our ability to conduct our future operations. On June 18, 2001, we exited bankruptcy under Chapter 11 of the U.S. Bankruptcy Code. Our prior bankruptcy may adversely affect the conduct of our future operations by causing vendors and others from whom we purchase goods or services to be reluctant to do business with us. These vendors may request payment in advance, refuse to extend us credit, or give us terms less favorable than our competitors. We currently do business with certain vendors that require us to pay in advance for goods or services. These limitations make us more susceptible to timing differences between our receipt of payment and our expenditures, which requires us to carefully manage our collections and disbursements, and may hinder our ability to adjust rapidly to changing market conditions. In addition, our recourse to bankruptcy protection were we to require it is limited for the 6 years following the date we filed bankruptcy, March 14, 2000, unless we waive the benefits of our past discharge. Our significant leverage and lack of capital resources may affect our ability to successfully operate and service our debt obligations. Our level of indebtedness as of June 30, 2001, was $130.0 million, as compared to adjusted EBITDA on a pro forma basis for the year ended December 31, 2000 of $42.0 million and for the six months ended June 30, 2001 of $36.8 million. Under the indenture we are permitted to incur, subject to certain conditions, up to $20.0 million of additional secured debt through the issuance of additional notes and additional amounts by other means. Our level of indebtedness and lack of capital resources could have several important effects on our future operations, which in turn could have important consequences to you as a holder of the notes, including, without limitation: - impairing our ability to obtain additional financing for working capital, capital expenditures or general corporate or other purposes in the future; - placing us at a competitive disadvantage relative to competitors that have less indebtedness, by requiring us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness and thereby reducing the availability of our cash flow to fund working capital, capital expenditures, general corporate expenditures and other purposes; - causing us to be unable to satisfy our amortization payments due on the notes on June 1, 2002, 2003 and 2004; - causing us to be unable to repurchase, upon a change of control, all of the outstanding notes, together with any accrued and unpaid interest to the date of repurchase; - causing us to be unable to repurchase notes pursuant to an asset sale offer or an excess cash flow offer; and - limiting or hindering our ability to adjust rapidly to changing market conditions, making us more vulnerable in the event of a downturn in general economic conditions or our business. Our ability to make scheduled payments of principal and interest with respect to our indebtedness, including the notes, or to refinance such obligations will depend on our financial and 14 operating performance, which, in turn, will be subject to prevailing economic conditions and to certain financial, business and other factors beyond our control. If our near-term cash flow is consumed by our debt service, we may be forced to reduce or delay planned capital expenditures, sell assets, obtain additional equity capital or attempt to restructure our indebtedness. Historically, we have financed acquisition, exploration and development activities primarily through various credit facilities and with internally generated funds. We currently intend to continue our development and exploration activities. However, our ability to expend the capital necessary to undertake or complete future activities may be limited and we may not have adequate funds available to us to carry out our growth strategy. Please read "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources," beginning on page 45, and our consolidated financial statements and the related notes included in this prospectus. Our estimates of oil and natural gas reserves and future net revenue are uncertain and inherently imprecise. This prospectus contains estimates of our proved reserves and the estimated future net revenues from our proved reserves. Estimating oil and natural gas reserves and their values involves numerous uncertainties, including many factors beyond our control. Reservoir engineering is a subjective process of estimating underground accumulations of oil and natural gas, which cannot be measured in an exact manner. Estimates of economically recoverable oil and natural gas reserves and of future net revenues necessarily depend upon a number of variable factors and assumptions, including the following: - historical production from the area compared with production from other producing areas; - the assumed effects of regulation by governmental agencies; and - assumptions concerning future oil and natural gas prices, future operating costs, severance and excise taxes, development costs and workover and remedial costs. Because of the variable factors and assumptions involved in the estimation of reserves, different engineers or the same engineers at different times may reach substantially different results in their estimates of the economically recoverable quantities of oil and natural gas attributable to any particular group of properties, their classification of reserves based on risk recovery and their estimates of the future net revenues expected from reserves. In addition, reserve estimates may be adjusted downward or upward because of changes in such factors and assumptions. Because all reserve estimates are subjective to some degree, each of the following items may differ materially from those assumed in the estimated reserves: - the quantities of oil and natural gas that are ultimately recovered; - the production and operating costs incurred; - the amount and timing of future development expenditures; and - future oil and natural gas prices. The present values of estimated future net revenues referred to in this prospectus should not be construed as the current market value of the estimated oil and natural gas reserves attributable to our properties. In accordance with applicable requirements of the SEC, the estimated discounted future net revenues from proved reserves are generally based on prices and costs as of the date of 15 the estimate, whereas actual future prices and costs may be materially higher or lower. Actual future net revenues also will be affected by factors such as: - the amount and timing of actual production; - supply and demand for oil and natural gas; - curtailments or increases in consumption by natural gas purchasers; and - changes in governmental regulations or taxation. The timing of actual future net revenues from proved reserves, and their actual present value, will be affected by both the timing of the production and the incurrence of expenses in connection with development and production of oil and natural gas properties. In addition, the calculation of the present value of the future net revenues using a 10% discount, as required by the SEC, is not necessarily the most appropriate discount factor based on interest rates in effect from time to time and risks associated with our reserves or the oil and natural gas industry in general. Oil and natural gas prices are volatile. A decline in prices could adversely affect our financial results, cash flows, access to capital and ability to pay debt. The price we receive for our oil and natural gas production has a significant effect on our financial results, profitability, future rate of growth and the carrying value of our oil and natural gas properties. Prices also affect the amount of cash flow available to pay debt, to make capital expenditures and our ability to borrow money or obtain other forms of financing. Historically, prices for oil and natural gas have been volatile and may continue to be volatile in the future. Additionally, oil and natural gas prices may vary significantly by geographic region and have been particularly volatile in California where much of our natural gas is produced and sold. The prices we are currently receiving for our production are near historic highs in all our areas. Wide fluctuations in oil and natural gas prices may result from relatively minor changes in the supply of and demand for oil and natural gas, market uncertainty and other factors beyond our control including: - worldwide and domestic supplies of oil and natural gas; - weather conditions; - the level of consumer demand; - the price and availability of alternative fuels; - the availability of pipeline capacity; - the price and level of foreign imports; - domestic and foreign governmental regulations and taxes; - the ability of the members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls; - political instability or armed conflict in oil producing regions; and - the overall economic environment. These factors and the volatility of the energy markets generally make it extremely difficult to predict future oil and natural gas price movements with any certainty. Declines in oil and natural gas prices would not only reduce revenue, but could reduce the amount of oil and natural gas that we can produce economically and, as a result, could adversely effect both our financial condition and our oil and natural gas reserves. 16 Drilling involves numerous risks, including the risk that no commercially productive oil or natural gas reservoirs will be encountered. Our success is significantly affected by risks associated with drilling and other operational activities. We do not ourselves conduct the actual drilling operations, but hire drilling companies at standard industry rates. Perhaps the most significant drilling risk is the risk that no oil or natural gas will be found that can be produced at a profit. New wells we drill may be unproductive or we may not be able to recover all or any portion of our investment in wells drilled. The seismic data and other technologies we may use do not allow us to know conclusively prior to drilling a well that oil or natural gas is present or may be produced economically. The cost of drilling, completing and operating a well is often uncertain, and cost factors can adversely affect the economics of a project. Our efforts will be unprofitable if we drill dry holes or wells that are productive but do not produce enough reserves to return a profit after drilling, operating and other costs. If we are not successful in finding productive oil and natural gas reservoirs or drilling productive oil and natural gas wells, or if drilling costs are significantly higher than projected, our financial results may suffer. Further, drilling operations may be curtailed, delayed or canceled as a result of a variety of factors, including the following: - unexpected drilling conditions; - pressure or irregularities in formations; - equipment failures or accidents; - adverse weather conditions; - compliance with environmental and other governmental requirements; - title problems; and - costs of, shortages of or delays in the availability or delivery of equipment or qualified operating personnel. Hedging transactions may limit our potential profits from operations. To manage our exposure to price risks in the marketing of our oil and natural gas production, we have in the past and will be required in the future under the terms of the indenture, subject to certain conditions, to enter into oil and natural gas price hedging arrangements with respect to a portion of our expected production. Our hedging arrangements may include futures contracts on the NYMEX. Our hedging transactions may limit our potential profits if oil and natural gas prices were to rise substantially over the price established by the hedge. Hedging transactions may expose us to the risk of loss in certain circumstances, including instances in which: - our production is materially less than expected; - there is volatility of price differentials between delivery points for our production and the delivery point assumed in the hedge arrangement or the sales prices for the quality of our oil and natural gas and the sales price of the quality assumed in the hedge; or - the counterparties to our future contracts fail to perform the contracts. In connection with the original offering, we agreed to maintain, on a monthly basis, a rolling two-year hedge program until the maturity of the old notes and the new notes, subject to certain conditions. Approximately 80% of our projected oil and natural gas production from proved developed producing reserves (and the basis differential attributable to approximately 80% of our projected proved developed producing natural gas production from our California properties) is hedged through June 30, 2003 at swap prices $4.19 per Mcf and $25.30 per Bbl, or a weighted-average natural gas-equivalent price of approximately $4.20 per Mcfe. 17 If we are unable to adequately replace our reserves, our ability to sustain production and our long-term financial performance will be adversely impacted. The volume of production from oil or natural gas properties generally decreases as more oil and natural gas is produced from a property and reserves are depleted. The rate at which the decrease occurs depends upon the geologic characteristics of a particular property. If we do not find new oil and natural gas production either by our exploration and development efforts or acquisition, then our proved reserves will decrease as we produce oil and natural gas. Our future oil and natural gas production rates are therefore highly dependent upon our level of success in finding, developing or acquiring additional reserves. Finding, developing or acquiring additional reserves requires significant capital expenditures. In addition, at December 31, 2000, approximately 34% of our total estimated proved reserves were undeveloped. By their nature, undeveloped reserves are less certain than developed reserves and recovery of such reserves will require greater capital expenditures and successful drilling operations. If we do not make significant capital expenditures, we may not be able to replace produced reserves. Historically, we have funded our capital expenditures primarily through various credit facilities and with internally generated funds. Future cash flows are subject to a number of variables, such as the level of production from existing wells, prices of oil and natural gas and our success in developing and producing new reserves. If revenue were to decrease as a result of lower oil and natural gas prices or decreased production, and our access to capital were limited, we would have a reduced ability to replace our reserves. Due to our limited capital resources and required debt repayment as discussed beginning on page 14 under the heading "-- Our significant leverage and lack of capital resources may affect our ability to successfully operate and service our debt obligations," if revenue were to decrease as a result of lower oil and natural gas prices or decreased production, we might not be able to make sufficient capital investments to replace our oil and natural gas reserves. Even if funds are available, we may not be able to successfully find, develop or acquire additional oil and natural gas proved reserves that are economically recoverable. Our business involves operating hazards and uninsured risks. Our drilling and production and other operations, and the transportation of production by others, also involve a number of hazards and risks such as fires, natural disasters, explosions, blowouts and spills. If any of these risks occur, we could sustain substantial losses as a result of: - injury or loss of life; - severe damage or destruction to property, natural resources and equipment; - pollution or other environmental damage; - clean-up responsibilities; - regulatory investigations and penalties; and - suspension of operations. We are not fully insured against some of these risks, either because the insurance is not available or because of high premium costs. If a significant accident or other event happens and is not fully covered by insurance, we could be required to pay some or all of the costs associated with the accident or event, which may require us to divest resources needed for other purposes. Also, we cannot predict the continued availability of insurance at premium levels that, in our sole discretion, justify its purchase. Our industry is extremely competitive and many of our competitors have superior resources. The energy industry is extremely competitive. This is especially true with regard to exploration for, and development and production of, new sources of oil and natural gas. As an independent producer of oil and natural gas, we encounter substantial competition in acquiring properties suitable for exploration, in contracting for drilling equipment and other services, in marketing oil and natural gas and in securing trained personnel. We frequently compete against companies that have 18 substantially larger financial resources, staffs and facilities. If we directly compete against one of those larger companies in a desired acquisition of oil and natural gas properties or in the hiring of experienced and skilled personnel, we may not have the resources available to obtain the desired result. We depend heavily on the services of key personnel and the loss of their services could have an adverse effect on our ability to operate. We depend to a large extent on the services of Richard Bowman, Jeffrey T. Janik and Suzanne R. Ambrose. The loss of the services of these key personnel could impair our ability to manage our business and properties. We do not currently have employment contracts with these key personnel and do not currently maintain key man life insurance on their lives. We believe that our success is also dependent upon our ability to continue to employ and retain skilled technical personnel. Higher oil and natural gas prices adversely affect the cost and availability of drilling and production services. Higher oil and natural gas prices, such as those we are currently experiencing, generally stimulate increased demand and result in increased prices for drilling rigs, crews and associated supplies, equipment and services. We have recently experienced significantly higher costs and reduced availability for drilling rigs and other related services and expect such costs to continue to escalate. Our operations are subject to significant government regulation that may change over time. Our oil and natural gas operations are subject to various federal, state and local governmental laws and regulations that may change in response to economic or political conditions. Matters subject to regulation include discharge permits for drilling operations, drilling and abandonment bonds or other financial responsibility requirements, reports concerning operations, the spacing of wells, utilization and pooling of properties, taxation and the environment. From time to time, regulatory agencies have imposed price controls and production limitations to conserve supplies of oil and natural gas. A significant portion of our production of natural gas is from our properties in the Sacramento Basin in California. As a result of the recent energy crises in California, certain bills are currently being considered by the California legislature which could impose civil and criminal penalties on producers of natural gas or electric power who curtail production or sell energy "at prices above marginal cost." We cannot determine at this time the effect, if any, that such legislation, were it enacted, would have on our operations. We are not aware that any similar legislation is currently proposed by any other state in which we operate. In addition, the production, handling, storage, transportation and disposal of oil and natural gas, their by-products and other substances and wastes generated, produced or used in connection with oil and natural gas operations are regulated under federal, state and local laws and regulations relating to the protection of health and the environment. These laws and regulations may impose increasingly strict requirements for water and air pollution control, spill cleanups and solid waste management. Our failure to meet any of the foregoing requirements could result in a suspension of our operations, as well as administrative, civil, and even criminal, penalties. See "Business and Properties -- Regulation" beginning on page 60 for more detail. We may not be able to profitably sell all of the oil and natural gas we produce. The marketability of our oil and natural gas production depends upon the availability and capacity of natural gas gathering systems, pipelines and processing facilities. If such capacity is not available, we might have to shut-in producing wells or delay or discontinue development plans for properties. In addition, federal and state regulation of oil and natural gas production and transportation, general economic conditions and changes in supply and demand could adversely affect our ability to produce and market our oil and natural gas on a profitable basis. 19 Our earnings may not be sufficient to cover fixed charges. For purposes of computing the ratio of earnings to fixed charges, earnings are computed as income after reorganization costs and before income taxes plus interest expense, including amortization of premiums, discounts, and capitalized expenses related to indebtedness. Fixed charges represent interest expense (including amortization of deferred finance charges and an estimated portion of rentals representing interest costs). Our earnings were insufficient to cover fixed charges by $15.8 million, $9.2 million, $5.7 and $20.6 million for the years ended December 31, 1998, 1999, 2000 and on a pro forma basis for the year ended December 31, 2000, respectively. If, in the future, our earnings are insufficient to cover our fixed charges, we may be unable to satisfy our obligations under the notes and indenture or may be required to dedicate a substantial portion of our cash reserves and other resources to cover these charges, reduce or delay planned capital expenditures, sell assets, obtain additional equity capital or attempt to restructure our indebtedness.

Tri-Union Operating Company, our wholly-owned subsidiary, is a Delaware corporation that was also formed in 1996 in connection with the Reunion acquisition. On July 27, 2001, we were the surviving corporation in a merger with our parent corporation, Tribo Petroleum Corporation. As a consequence of the merger, we assumed all of the rights and obligations of Tribo. Tribo was incorporated in Texas in 1992 by Mr. Bowman to acquire and develop oil and natural gas properties, typically by serving as operator and retaining a working interest in its properties while financing its net drilling costs through the sale of a majority of the working interest. Tribo had only a few properties and no significant reserves until 1996, when it acquired Reunion. The acquisition of Reunion was structured so that Tri-Union Development acquired substantially all of Reunion's operations except a net profit interest in the Sutter Buttes field, which was acquired by Tri-Union Operating. Tri-Union Operating's interest in the Sutter Buttes field is its only oil and natural gas property and represents less than approximately 5% of our consolidated net proved oil and natural gas reserves. In March 1998, we acquired certain onshore Texas oil and natural gas properties from Apache Corporation with proceeds from a short-term, amortizing bank loan. In August 1998, before we were able to refinance our bank loan, commodity prices began falling, with oil prices ultimately reaching a 12-year low in December of that year. The resultant negative effect on our cash flow from the deterioration of commodity prices, coupled with the required amortization payments on our bank loan, severely restricted the amount of capital we were able to dedicate to development drilling. Consequently, our oil and natural gas production declined, further negatively affecting our cash flow. In October 1998, our short-term loan matured and we arranged a forbearance agreement providing for interest payments to be partially capitalized and providing us with additional time to refinance our obligations. In July 1999, this forbearance agreement terminated and we made negotiated interest payments while attempting to negotiate a restructuring of our obligations. By March 2000, the aggregate principal balance of our debt had increased as a result of capitalized interest and expenses to approximately $105 million. In February 2000, the bank declared a default on the loan, demanded payment of all principle and interest and posted the shares of Tribo Petroleum Corporation, our parent corporation and a guarantor of the loan, for foreclosure. As a consequence of the bank's foreclosure action, on March 14, 2000, we filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code. Tri-Union Operating continued to operate outside of bankruptcy. We filed our amended plan of reorganization in the bankruptcy proceeding on May 9, 2001. Our plan was confirmed by a court order entered as of May 23, 2001, subject to the completion of the original offering. On June 18, 2001, the original offering closed and we exited bankruptcy. The proceeds of the offering and our available cash balances at closing were sufficient to allow us to pay or segregate funds for the payment of all claims. 21 THE EXCHANGE OFFER PURPOSE OF THE EXCHANGE OFFER The old notes were issued on June 18, 2001, as part of a unit offering (the "original offering"), each unit consisting of one old note in the principal amount of $1,000 and one share of the class A common stock of Tribo Petroleum Corporation, our former parent corporation. The units were sold to Jefferies & Company, Inc., in reliance upon the exemption provided by Section 4(2) of the Securities Act. Jefferies then sold the units to qualified institutional buyers in reliance on Rule 144A under the Securities Act. In connection with the sale of the old notes, we entered into a registration rights agreement with Jefferies. The sole purpose of the exchange offer is to fulfill our obligations under the registration rights agreement. The registration rights agreement provides that unless the exchange offer would not be permitted by applicable law or SEC policy, we will (i) file an exchange offer registration statement with the SEC on or prior to 60 days after the date of original issuance of the old notes, (ii) use our best efforts to have the exchange offer registration statement declared effective by the SEC on or prior to 120 days after the date of original issuance of the old notes, (iii) commence the exchange offer and use our best efforts to issue, on or prior to 60 days after the date on which the exchange offer registration statement was declared effective by the SEC, publicly registered notes, in exchange for all old notes tendered prior thereto in the exchange offer; provided that if we have not consummated the exchange offer within 180 days of the date of original issuance of the old notes, then we will file the shelf registration statement with the SEC on or prior to the 181st day after the date of original issuance of the old notes and use our best efforts to cause the shelf registration statement to be declared effective within 60 days after such filing. We will be required to use our best efforts to keep the shelf registration statement continuously effective, supplemented and amended until the second anniversary of the date of original issuance of the old notes or such shorter period that will terminate when all the transfer restricted notes covered by the shelf registration statement have been sold. If (i) we fail to file any of the registration statements required by the registration rights agreement on or before the date specified for such filing, (ii) any of the registration statements is not declared effective by the SEC or prior to the date specified for effectiveness, (iii) we fail to consummate the exchange offer within 60 days of the date specified for effectiveness with respect to the exchange offer registration statement, or (iv) the shelf registration statement with respect to the notes or the exchange offer registration statement is declared effective but thereafter, subject to certain exceptions, ceases to be effective or usable in connection with the exchange offer or resales of transfer restricted notes, as the case may be, during the periods specified in the registration rights agreement, then the interest rate on the old notes will increase, with respect to the first 90-day period immediately following the occurrence of any default referred to above by 0.50% per annum and will increase by an additional 0.50% per annum with respect to each subsequent 90-day period until all such defaults have been cured, up to a maximum amount of 2% per annum with respect to all such defaults. Following the cure of all such defaults, the accrual of all such additional interest will cease and the interest rate will revert to the original rate. Each broker-dealer that receives new notes for its own account in exchange for old notes, where such notes were acquired by the broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. See "Plan of Distribution" beginning on page 118. TERMS OF THE EXCHANGE OFFER We offer to exchange, upon the terms and subject to the conditions set forth herein and in the letter of transmittal, up to $130,000,000 in principal amount of new senior secured notes for up to $130,000,000 in principal amount of old senior secured notes. The terms of the new notes are 22 identical in all material respects to the terms of the old notes, except that the new notes will not generally be subject to the transfer restrictions applicable to the old notes and the holders of the new notes (as well as remaining holders of any old notes) will not be entitled to registration rights under the registration rights agreement. The new notes will evidence the same debt as the old notes and will be entitled to the benefits of the indenture pursuant to which such old notes were issued. See "Description of the Senior Secured Notes" beginning on page 71. Based on interpretations by the staff of the SEC, as set forth in no-action letters issued to third parties, we believe that the new notes issued in the exchange offer for old notes may be offered for resale, resold or otherwise transferred by holders thereof (other than any such holder which is an "affiliate" of us within the meaning of Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that the new notes are acquired in the ordinary course of the holder's business and the holder has no arrangement with any person to participate in the distribution of the new notes. However, we have not requested the SEC to issue, and the SEC has not issued, a no-action letter with regard to the exchange offer, and there is no assurance that the staff of the SEC would make a similar determination with respect to the exchange offer as in such other circumstances. Each holder, other than a broker-dealer, will be required to acknowledge that it is not engaged in, and does not intend to engage in, a distribution of new notes and has no arrangement or understanding to participate in a distribution of new notes. If any holder is an affiliate of us, is engaged in or intends to engage in or has any arrangement or understanding with respect to the distribution of the new notes to be acquired in the exchange offer, the holder cannot rely on the applicable interpretations of the staff of the SEC and must comply with registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction. Each broker-dealer that receives new notes for its own account in the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of the new notes. The letter of transmittal states that by so acknowledging and by delivering a prospectus a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new notes received in exchange for old notes where the old notes were acquired by the broker-dealer as a result of market-making activities or other trading activities (other than old notes acquired directly from us). We have agreed that for a period of 180 days following the consummation of the exchange offer we will make this prospectus available to any broker-dealer for use in connection with any resale. See "Plan of Distribution" beginning on page 118. Tendering holders of old notes will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of the old notes. Interest on each new note will accrue from the last date on which interest was paid on such old notes surrendered in exchange therefor or, if no interest has been paid, from the date of original issuance of the old notes. Holders whose old notes are accepted for exchange will receive accrued interest to, but not including, the date of issuance of the new notes, such interest to be payable with the first interest payment on the new notes, but will not receive any payment in respect of interest on the old notes accrued after the issuance of the new notes. EXPIRATION DATE; EXTENSIONS; TERMINATION; AMENDMENTS The exchange offer expires at 5:00 p.m., New York City time on , 2001, unless we in our sole discretion extend the period during which the exchange offer is open. We will be entitled to close the exchange offer 30 days after commencement, provided, however, that we have accepted all old notes theretofore validly surrendered in accordance with the term of the exchange offer. We reserve the right to extend the exchange offer at any time and from time to time prior to the expiration date by giving written notice to Firstar Bank, National Association (the "Exchange Agent") 23 and by timely public announcement communicated, unless otherwise required by applicable law or regulation, by making a press release. During any extension of the exchange offer, all old notes previously tendered will remain subject to the exchange offer. We expressly reserve the right to terminate the exchange offer and not accept for exchange any old notes for any reason, including if any of the events set forth below under "-- Conditions to the Exchange Offer" shall have occurred and shall not have been waived by us and to amend the terms of the exchange offer in any manner, whether before or after any tender of the old notes. Terms of the exchange offer which affect the note holders only shall not be amended, modified or supplemented, nor will waivers from such provisions be given unless we have obtained the written consent of the holders of at least a majority in aggregate principal amount of the old notes. If any termination or amendment occurs, we will notify the Exchange Agent in writing and will either issue a press release or give written notice to the holders of the old notes as promptly as practicable. Unless we terminate the Exchange Offer prior to 5:00 p.m. New York City time, on the date set forth above, we will exchange the new notes for the old notes promptly following the expiration of the exchange offer. If we waive any material condition to the exchange offer, or amend the exchange offer in any other material respect, and if the exchange offer is scheduled to expire less than five business days from and including the date notice of the waiver or amendment is first published, sent or given to holders of old notes, then the exchange offer will be extended until the expiration of such period of five business days. This prospectus and the related letter of transmittal and other relevant materials will be mailed by us to record holders of old notes and will be furnished to brokers, banks and similar persons whose names, or the names of whose nominees, appear on the lists of holders for subsequent transmittal to beneficial owners of old notes. EXCHANGE OFFER PROCEDURES The tender of old notes to us by a holder pursuant to one of the procedures set forth below will constitute an agreement between the holder and us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal. All references in this prospectus to the letter of transmittal are deemed to include a facsimile of the letter of transmittal. General Procedures. A holder of an old note may tender the same by: - properly completing and signing the letter of transmittal or a facsimile thereof; - properly completing any required signature guarantees; - properly completing any other documents required by the letter of transmittal; and - delivering all of the above, together with the certificate or certificates representing the old notes being tendered, to the Exchange Agent at its address set forth below under "-- Exchange Agent" on or prior to the expiration date; or - complying with the procedure for book-entry transfer described below; or - complying with the guaranteed delivery procedures described below. The signature on the letter of transmittal need not be guaranteed if: - tendered old notes are registered in the name of the signer of the letter of transmittal; and - the new notes are registered in the name of the signer of the letter of transmittal; and - any untendered old notes are to be reissued in the name of the holder. 24 In any other case, the tendered old notes must be: - endorsed or accompanied by written instruments of transfer in form satisfactory to us; - the signature on the endorsement or instrument of transfer must be guaranteed by a bank, broker, dealer, credit union, savings association, clearing agency or other institution, each an "eligible guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange Act and that is a member of a recognized signature guarantee medallion program (an "Eligible Institution"). If the new notes and/or old notes not exchanged are to be delivered to an address other than that of the registered holder appearing on the note register for the old notes, the signature in the letter of transmittal must be guaranteed by an Eligible Institution. Any beneficial owner whose old notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and who wishes to tender old notes should contact the registered holder promptly and instruct the holder to tender old notes on the beneficial owner's behalf. If the beneficial owner wishes to tender the old notes himself, the beneficial owner must, prior to completing and executing the letter of transmittal and delivering the old notes, either make appropriate arrangements to register ownership of the old notes in such beneficial owner's name or follow the procedures described in the immediately preceding paragraph. The transfer of record ownership may take considerable time. THE METHOD OF DELIVERY OF OLD NOTES AND ALL OTHER DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER. IF SENT BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, RETURN RECEIPT REQUESTED, BE USED, PROPER INSURANCE BE OBTAINED, AND THE MAILING BE MADE SUFFICIENTLY IN ADVANCE OF THE EXPIRATION DATE TO PERMIT DELIVERY TO THE EXCHANGE AGENT ON OR BEFORE THE EXPIRATION DATE. Book-Entry Transfer. The old notes were issued as global securities in fully registered form without interest coupons. Beneficial interests in the global securities, held by direct or indirect participants in the DTC, are shown on, and transfers of these interests are effected only through, records maintained in book-entry form by the DTC with respect to its participants. The Exchange Agent will make a request within two business days after receipt of this prospectus to establish an account with respect to the book-entry interests at the DTC for purposes of facilitating the exchange offer unless a suitable account has already been established. You must deliver your book-entry interest by book-entry transfer to the account maintained by the Exchange Agent at the DTC. Any financial institution that is a participant in the DTC's systems may make book-entry delivery of book-entry interests by causing the DTC to transfer the book-entry interests into the Exchange Agent's account at the DTC in accordance with the DTC's procedures for transfer. If you hold your old notes in the form of book-entry interests and you wish to tender your old notes for exchange, you must transmit to the Exchange Agent on or prior to the expiration date either: a written or facsimile copy of a properly completed and duly executed letter of transmittal, including all other documents required by the letter of transmittal, to the Exchange Agent at the address set forth below under "-- Exchange Agent"; or a computer-generated message transmitted by means of the DTC's Automated Tender Offer Program system and received by the Exchange Agent and forming a part of a confirmation of book-entry transfer, in which you acknowledge and agree to be bound by the terms of the letter of transmittal. In addition, in order to deliver old notes held in the form of book-entry interests, a timely confirmation of book-entry transfer of those old notes into the Exchange Agent's account at the DTC must be received by the Exchange Agent prior to the expiration date or you must comply with the guaranteed delivery procedures described below. 25 Certificated Old Notes. If your old notes are certificated old notes and you wish to tender those notes for exchange pursuant to the exchange offer, you must transmit to the Exchange Agent on or prior to the expiration date a written or facsimile copy of a properly completed and duly executed letter of transmittal, including all other required documents, to the address set forth below under "-- Exchange Agent." In addition, in order to validly tender your certificated old notes, the certificates representing your old notes must be received by the Exchange Agent prior to the expiration date or you must comply with the guaranteed delivery procedures described below. Guaranteed Delivery Procedures. If a holder desires to accept the exchange offer and time will not permit a letter of transmittal or old notes to reach the Exchange Agent before the expiration date, a tender may be effected if the Exchange Agent has received at the address specified below under "-- Exchange Agent" on or prior to the expiration date a letter or facsimile transmission from an Eligible Institution setting forth the name and address of the tendering holder, the names in which the old notes are registered and, if possible, the certificate number of the old notes to be tendered, and stating that the tender is being made thereby and guaranteeing that within three New York Stock Exchange trading days after the date of execution of such letter or facsimile transmission by the Eligible Institution, the old notes, in proper form for transfer, will be delivered by the Eligible Institution together with a properly completed and duly executed letter of transmittal (and any other required documents). Unless old notes being tendered by the above-described method (or a timely Book-Entry Confirmation) are deposited with the Exchange Agent within the time period set forth above (accompanied or preceded by a properly completed letter of transmittal and any other required documents), we may, at our option, reject the tender. Copies of a Notice of Guaranteed Delivery which may be used by Eligible Institutions for the purposes described in this paragraph are being delivered with this prospectus and the related letter of transmittal. A tender will be deemed to have been received as of the date when the tendering holder's properly completed and duly signed letter of transmittal accompanied by the old notes or a timely book-entry confirmation is received by the Exchange Agent. Issuances of new notes in exchange for old notes tendered pursuant to a Notice of Guaranteed Delivery or letter or facsimile transmission to similar effect (as provided above) by an Eligible Institution will be made only against deposit of the letter of transmittal (and any other required documents) and the tendered old notes or a timely book-entry confirmation. All questions as to the validity, form, eligibility (including time of receipt) and acceptance for exchange of any tender of old notes will be determined by us and shall be final and binding on all parties. We reserve the absolute right to reject any or all tenders not in proper form or the acceptance of which, or exchange for which, may, in the opinion of counsel to us, be unlawful. We also reserve the absolute right, subject to applicable law, to waive any of the conditions of the exchange offer or any defects or irregularities in tenders of any particular holder whether or not similar defects or irregularities are waived in the case of other holders. Our interpretation of the terms and conditions of the exchange offer (including the letter of transmittal and the instructions thereto) will be final and binding. No tender of old notes will be deemed to have been validly made until all defects and irregularities with respect to such tender have been cured or waived. Neither we, the Exchange Agent nor any other person shall be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Each broker-dealer that receives new notes for its own account in exchange for old notes, where the notes were acquired by the broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. See "Plan of Distribution" beginning on page 118. TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL The letter of transmittal contains, among other things, the following terms and conditions, which are part of the exchange offer. 26 The party tendering old notes for exchange exchanges, assigns and transfers the old notes to us and irrevocably constitutes and appoints the Exchange Agent as the Transferor's agent and attorney-in-fact to cause the old notes to be assigned, transferred and exchanged. The transferor represents and warrants that it has full power and authority to tender, exchange, sell, assign and transfer the old notes, and that, when the same are accepted for exchange, we will acquire good, marketable and unencumbered title to the tendered old notes, free and clear of all liens, restrictions, changes and encumbrances and not subject to any adverse claim. The transferor also warrants that it will, upon request, execute and deliver any additional documents deemed by us or the Exchange Agent to be necessary or desirable to complete the exchange, assignment and transfer of tendered old notes. All authority conferred by the transferor will survive the death or incapacity of the transferor and every obligation of the transferor shall be binding upon the heirs, legal representatives, successors, assigns, executors and administrators of such transferor. The transferor certifies that it is not an "affiliate" of ours within the meaning of Rule 405 under the Securities Act and that it is acquiring the new notes offered hereby in the ordinary course of the transferor's business and that the transferor has no arrangement with any person to participate in the distribution of the new notes. If the transferor is not a broker-dealer, it represents that it is not engaged in, and does not intend to engage in, a distribution of new notes. If the transferor is a broker-dealer that will receive new notes for its own account in exchange for old notes, it represents that the old notes to be exchanged for new notes were acquired by it as a result of market-making activities or other trading activities and acknowledges that it will deliver a prospectus meeting the requirements of the Securities Act of 1933 in connection with any resale of new notes acquired in the exchange offer; however, by so acknowledging and by delivering a prospectus, the transferor will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. WITHDRAWAL RIGHTS Old notes tendered in the exchange offer may be withdrawn at any time prior to the Expiration Date. For a withdrawal to be effective, a written or facsimile transmission of notice of withdrawal must be timely received by the Exchange Agent at its address set forth below under "-- Exchange Agent" on or prior to the expiration date. Any notice of withdrawal must specify the person named in the letter of transmittal as having tendered old notes to be withdrawn, the certificate numbers of old notes to be withdrawn, the aggregate principal amount of old notes to be withdrawn (which must be an authorized denomination), that the holder is withdrawing his election to have the old notes exchanged, and the name of the registered holder of such old notes, if different from that of the person who tendered the old notes. Additionally, the signature on the notice of withdrawal must be guaranteed by an Eligible Institution (except in the case of old notes tendered for the account of an Eligible Institution). The Exchange Agent will return the properly withdrawn old notes promptly following receipt of notice of withdrawal. All questions as to the validity of notices of withdrawals, including time of receipt, will be final and binding on all parties. If old notes have been tendered pursuant to the procedures for book entry transfer, the notice of withdrawal must specify the name and number of the account at the DTC to be credited with the withdrawal of old notes, in which case a notice of withdrawal will be effective if delivered to the Exchange Agent by written or facsimile transmission. Withdrawals of tenders of old notes may not be rescinded. Old notes properly withdrawn will not be deemed validly tendered for purposes of the exchange offer, but may be retendered at any subsequent time on or prior to the Expiration Date by following any of the procedures described herein. 27 ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES Upon the terms and subject to the conditions of the exchange offer, the acceptance for exchange of old notes validly tendered and not withdrawn and the issuance of the new notes will be made promptly following the expiration date. For the purposes of the exchange offer, we shall be deemed to have accepted for exchange validly tendered old notes when, as and if we had given notice of acceptance to the Exchange Agent. The Exchange Agent will act as agent for the tendering holders of old notes for the purposes of receiving new notes from us and causing the old notes to be assigned, transferred and exchanged. Upon the terms and subject to the conditions of the exchange offer, delivery of new notes to be issued in exchange for accepted old notes will be made by the Exchange Agent promptly after acceptance of the tendered old notes. Old notes not accepted for exchange by us will be returned without expense to the tendering holders or in the case of old notes tendered by book-entry transfer into the Exchange Agent's account at the DTC promptly following the expiration date or, if we terminate the exchange offer prior to the expiration date, promptly after the exchange offer is terminated. CONDITIONS TO THE EXCHANGE OFFER Notwithstanding any other provision of the exchange offer, or any extension of an exchange offer, we will not be required to issue new notes in respect of any properly tendered old notes not previously accepted and may terminate the exchange offer (by oral or written notice to the Exchange Agent and by timely public announcement communicated, unless otherwise required by applicable law or regulation, by making a press release or, at our option, modify or otherwise amend the exchange offer, if (i) the exchange offer, or the making of any exchange by a note holder, would violate applicable law or any applicable interpretation of the staff of the SEC, (ii) an action or proceeding shall have been instituted or threatened in any court or by or before any governmental agency or body with respect to the exchange offer, (iii) there shall have been adopted or enacted any law, statute, rule or regulation prohibiting or limiting the exchange offer, (iv) there shall have been declared by United States federal or New York state authorities a banking moratorium, or (v) trading on the New York Stock Exchange or generally in the United States over-the-counter market shall have been suspended by order of the SEC or any other governmental authority. The foregoing conditions are for our sole benefit and may be asserted by us with respect to all or any portion of the exchange offer regardless of the circumstances (including any action or inaction by us) giving rise to such condition or may be waived by us in whole or in part at any time or from time to time in our sole discretion. Our failure at any time to exercise any of the foregoing rights will not be deemed a waiver of any right, and each right will be deemed an ongoing right which may be asserted at any time or from time to time. In addition, we have reserved the right, notwithstanding the satisfaction of each of the foregoing conditions, to terminate or amend the exchange offer. Any determination by us concerning the fulfillment or non-fulfillment of any conditions will be final and binding upon all parties. In addition, we will not accept for exchange any old notes tendered and no new notes will be issued in exchange for any old notes, if at such time any stop order shall be threatened or in effect with respect to the registration statement of which this prospectus constitutes a part or qualification under the Trust Indenture Act of 1939 (the "Trust Indenture Act") of the indenture pursuant to which such old notes were issued. 28 EXCHANGE AGENT Firstar Bank, National Association has been appointed as the Exchange Agent of the exchange offer. All executed letters of transmittal should be directed to the Exchange Agent at its address set forth below. Questions and requests for assistance, requests for additional copies of this prospectus or of the letter of transmittal and requests for Notices of Guaranteed Delivery should be directed to the Exchange Agent addressed as follows: <Table> By Mail/Hand Delivery/Overnight Delivery: Firstar Bank, National Association MN-SP-12CT 101 Fifth Street St. Paul, Minnesota 55101-1860 Attn: Frank Leslie </Table> Via Facsimile: (651) 229-6415 Confirm by telephone: (651) 229-2600 You should direct questions and requests for assistance, requests for additional copies of this prospectus or of the letter of transmittal and requests for notices of guaranteed delivery to the exchange agent at the address and telephone number set forth in the letter of transmittal. Delivery to an address other than as set forth above, or transmissions of instructions via facsimile number other than the ones set forth above, will not constitute a valid delivery. SOLICITATIONS OF TENDERS; EXPENSES We have not retained any dealer-manager or similar agent in connection with the exchange offer and will not make any payments to brokers, dealers or others for soliciting acceptances of the exchange offer. We will, however, pay the Exchange Agent reasonable and customary fees for its services and will reimburse it for reasonable out-of-pocket expenses. We will also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding tenders for their customers. The expenses to be incurred in connection with the exchange offer, including the fees and expenses of the Exchange Agent and printing, accounting and legal fees, will be paid by us. No person has been authorized to give any information or to make any representations in connection with the exchange offer other than those contained in this prospectus. If given or made, information or representations should not be relied upon as having been authorized by us. Neither the delivery of this prospectus nor any exchange made based upon this prospectus shall, under any circumstances, create any implication that there has been no change in our affairs since the respective dates as of which information is given. The exchange offer is not being made to (nor will tenders be accepted from or on behalf of) holders of old notes in any jurisdiction in which the making of the exchange offer or the acceptance of the exchange offer would not be in compliance with the laws of such jurisdiction. However, we may, at our discretion, take such action as we deem necessary to make the exchange offer in any such jurisdiction and extend the exchange offer to holders of old notes in such jurisdiction. In any jurisdiction the securities laws or blue sky laws of which require the exchange offer to be made by a licensed broker or dealer, the exchange offer is being made on our behalf by one or more registered brokers or dealers that are licensed under the laws of such jurisdiction. ACCOUNTING TREATMENT The new notes will be recorded at the same carrying value as the old notes, which is the principal amount as reflected in our accounting records on the expiration date. Accordingly, no gain 29 or loss for accounting purposes will be recognized. For accounting purposes, the expenses of the exchange offer will be deferred and amortized as interest expense over the life of the notes. APPRAISAL RIGHTS Holders of old notes will not have dissenters' rights or appraisal rights in connection with the exchange offer. OTHER Participation in the exchange offer is voluntary and holders should carefully consider whether to accept. Holders of the old notes are urged to consult their financial and tax advisors in making their own decisions on what action to take. As a result of the making of, and upon acceptance for exchange of all validly tendered old notes pursuant to the terms of this exchange offer, we will have fulfilled a covenant contained in the registration rights agreement. Holders of the old notes who do not tender their certificates in the exchange offer will continue to hold such certificates and will be entitled to all the rights and limitations under the indenture pursuant to which the old notes were issued, except for any such rights under the registration rights agreement which by its terms terminates or ceases to have further effect as a result of the making of this exchange offer. See "Registration Rights" beginning on page 119. All untendered old notes will continue to be subject to the restrictions on transfer set forth in the old notes and the indenture. To the extent that old notes are tendered and accepted in the exchange offer, the trading market, if any, for the old notes could be adversely affected. We may in the future seek to acquire untendered old notes in open market or privately negotiated transactions, through subsequent exchange offer or otherwise. We have no present plan to acquire any old notes which are not tendered in the exchange offer. 30 USE OF PROCEEDS The exchange offer is intended to satisfy certain of our obligations under the registration rights agreement. We will not receive any cash proceeds from the issuance of the new notes pursuant to the exchange offer. The net proceeds from the original offering, prior to the discount to Jefferies & Company, Inc., as initial purchaser, were approximately $122.9 million. We used the net proceeds of the original offering and approximately $55.5 million of our available cash balances, to pay or segregate funds for the payment of all claims in accordance with our plan. We intend to use our remaining funds to pursue our low-risk development drilling program and for working capital.

Adjusted EBITDA means EBITDA before impairment of oil and natural gas properties, reorganization costs and gains or losses on derivative contracts. EBITDA is commonly used by debt holders and financial statement users as a measurement to determine the ability of an entity to meet its interest obligations. EBITDA is not a measurement presented in accordance with generally accepted accounting principles ("GAAP") and is not intended to be used in lieu of GAAP presentation of results of operations and cash provided by operating activities. Our definition of adjusted EBITDA may not be identical to similarly entitled measures used by other companies. (2) Cash interest excludes non-cash interest for amortization of bond discount and bond issuance costs, which are included in determining interest expense in accordance with GAAP. (3) For purposes of computing the ratio of earnings to fixed charges, earnings are computed as income after reorganization costs and before income taxes plus interest expense including amortization of premiums, discounts, and capitalized expenses related to indebtedness. Fixed charges represent interest expense and capitalized interest (including amortization of deferred finance charges and an estimated portion of rentals representing interest costs). Earnings were insufficient to cover fixed charges by $15.8 million, $9.2 million and $5.7 million for the years ended December 31, 1998, 1999 and 2000, respectively. NM means "not measured." (4) ACNTA means Adjusted Consolidated Net Tangible Assets, as defined in "Description of the Senior Secured Notes -- Certain Definitions." ACNTA is calculated using oil and natural gas prices utilized in our year end reserve report. NM means "not measured." 34 UNAUDITED CONDENSED PRO FORMA FINANCIAL DATA The following unaudited condensed pro forma financial data consists of our unaudited condensed pro forma consolidated statement of our operations for the year ended December 31, 2000 and the six months ended June 30, 2001.

(2) Represents PV-10 Value adjusted for the effects of future estimated income tax expense. 37 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion of our results of operations and financial condition includes the results of operations and financial condition of our subsidiary and us on a consolidated basis. Our consolidated financial statements and the related notes contain additional detailed information that should be referred to when reviewing this material. GENERAL We are an independent oil and natural gas company engaged in the acquisition, development, exploration and production of oil and natural gas properties in three core areas. We commenced operations in 1992 and from our inception until mid-1996 we primarily acquired and developed properties onshore in south and southeast Texas. We expanded into the Sacramento Basin of northern California with our acquisition of Reunion in 1996. We established a core area of operation in the shallow waters of the Gulf of Mexico in 1997 with acquisitions from Apache and Statoil. In 1998 we expanded our onshore Gulf Coast properties by completing our largest acquisition to date, the $63.0 million acquisition of onshore Texas oil and natural gas properties from Apache. We have since focused our efforts and capital resources on developing our assets. We have one subsidiary, Tri-Union Operating Company, which is wholly owned by us. Tri-Union Operating's principal asset is a net profits interest in a field operated by us. This interest is the only oil and natural gas property of Tri-Union Operating and represents less than 5% of our consolidated proved reserves. In March 1998, we acquired certain onshore Texas oil and natural gas properties from Apache Corporation with the proceeds from a short-term, amortizing bank loan. In August 1998, before we were able to refinance our bank loan, commodity prices began falling, with oil prices ultimately reaching a 12-year low in December 1998. The resultant negative effect on our cash flow from the deterioration of commodity prices, coupled with the required amortization payments on our bank loan, severely restricted the amount of capital we were able to dedicate to development drilling. Consequently, our oil and natural gas production declined, further negatively affecting our cash flow. In October 1998, our short-term loan matured and we arranged a forbearance agreement providing for interest payments to be partially capitalized. On July 1999, this forbearance agreement terminated and we made negotiated interest payments while attempting to negotiate a restructuring of our obligations. On March 14, 2000, we chose to seek protection under Chapter 11 of the U.S. Bankruptcy Code. Tri-Union Operating continued to operate outside of bankruptcy. On July 18, 2001, we sold in a private unit offering $130,000,000 of old notes, each unit consisting of one old note in the principal amount of $1,000 and one share of class A common stock of Tribo Petroleum Corporation, our former parent corporation. The proceeds from this offering and our available cash balances were sufficient to allow us to pay or segregate funds for the payment of all creditor claims in full, including interest, and to exit bankruptcy on June 18, 2001. As of June 30, 2001, we had $105.6 million of debt outstanding (net of bond discounts), as compared to adjusted EBITDA on a pro forma basis for the six months then ended of $36.8 million and for the year ended December 31, 2000, of $42.0 million. At December 31, 2000, our net proved reserves were 180.1 Bcfe with a PV-10 Value of $630.0 million. At December 31, 1999, our net proved reserves were 205.2 Bcfe with a PV-10 Value of $292.5 million. While our total proved reserves quantities at December 31, 2000 decreased by 12% versus those at December 31, 1999, our proved developed producing reserves actually increased by 3% over the same period. The decrease in total proved reserves was primarily due to lease expirations that resulted in the loss of proved undeveloped reserves in our offshore Gulf Coast area. These leases expired as a consequence of our inability to obtain approval from the bankruptcy 38 court to make the significant capital investments required to maintain these leases. Our capital budget has been primarily focused on converting proved developed non-producing and proved undeveloped reserves to production. During 1998, 1999, 2000 and the first quarter of 2001, our capital expenditures on oil and natural gas activities totaled approximately $72.0 million, $13.6 million, $10.9 million and $1.4 million, respectively. These expenditures related to operations in our three core areas. In 1998, 87% of our capital expenditures were related to the acquisition of reserves. In 1999 and 2000, 44%, or $10.6 million, of our capital expenditures were for development drilling and recompletions. The remaining 56% was incurred on items such as platform and pipeline improvements that were identified at the time of our acquisition of the properties, compressor installations and on 3-D seismic surveys. During 1999 and 2000 our development capital investments of $10.6 million were expended to complete 28 development wells, exploitation wells and recompletions. With our working capital from the original offering and cash flow from operations, we plan to significantly increase our capital budget for the remainder of 2001 through 2003 to $37.7 million, to complete 116 development drilling, exploitation and recompletion projects and two seismic surveys. On July 27, 2001, we were the surviving corporation in a merger with our parent corporation, Tribo Petroleum Corporation. As a consequence of this merger, we assumed all of the rights and obligations of Tribo, including those under the indenture. The financial information in this prospectus is the consolidated financial information for Tribo, us and our subsidiary as of the periods indicated. We use the full cost method of accounting for oil and natural gas property acquisition, exploration and development activities. Under this method, all productive and nonproductive costs incurred in connection with the acquisition of, exploration for and development of oil and natural gas reserves are capitalized. Capitalized costs include lease acquisitions, geological and geophysical work, delay rentals and the costs of drilling, completing and equipping oil and natural gas wells. Gains or losses are recognized only upon sales or dispositions of significant amounts of oil and natural gas reserves. Proceeds from all other sales or dispositions are treated as reductions to capitalized costs. RESULTS OF OPERATIONS Six Months Ended June 30, 2001 Compared to Six Months Ended June 30, 2000 For the six months ended June 30, 2001, consolidated net income was $19,180,648, an improvement over consolidated net income of $2,806,530 for the six months ended June 30, 2000. Oil and Gas Revenues. Oil and natural gas revenues increased $28,479,224, or 109%, to $54,666,487 for the six months ended June 30, 2001, from $26,187,263 for the six months ended June 30, 2000. The increase in oil and natural gas revenues was primarily the result of an increase in production volumes and a substantial increase in the average price we received for natural gas during the period, which may not reflect the prices we receive in future periods. The following table summarizes the consolidated results of oil and natural gas production and related pricing for the six months ended June 30, 2001 and 2000: <Table> <Caption> FOR THE SIX MONTHS ENDED JUNE 30, -------------------------- 2000 2001 % CHANGE ------ ------ -------- Oil production volumes (Mbbls).......................... 540 692 28% Gas production volumes (Mmcf)........................... 3,413 4,615 35% Total (Mmcfe)................................. 6,653 8,767 32% Average oil price (per Bbl)............................. $29.27 $27.12 (7)% Average gas price (per Mcf)............................. $ 2.93 $ 7.78 166% Average price (per Mcfe)...................... $ 3.94 $ 6.24 58% </Table> 39 Gain or Loss on Marketable Securities. We recognized $417,180 in losses on marketable securities for the six months ended June 30, 2001, as compared to gains of $902,696 at June 30, 2000. Marketable securities bought and held principally for the purpose of sale in the near term are classified as trading securities. Trading securities are recorded at fair value on the balance sheet as current assets, with the change in fair value recognized during the period included in earnings. Other Income. Other income increased $477,616, or 114%, to $896,922 for the six months ended June 30, 2001 from $419,306 for the six months ended June 30, 2000. The increase was primarily the result of the sale of emission reduction credits from our Hastings Field. Lease Operating Expense. Lease operating expense increased $3,676,286, or 54%, to $10,480,429 for the six months ended June 30, 2001 from $6,804,142 for the six months ended June 30, 2000. Lease operating expense was $1.20 per Mcfe for the six months ended June 30, 2001, an increase of 17% from $1.02 per Mcfe for the six months ended June 30, 2000. The increase in lease operating expense is primarily the result of higher electricity and fuel costs, an increase in the number of producing wells and MMS compliance work at our Matagorda Island A-4 and Brazos 104 facilities. Workover Expense. Workover expense increased $1,643,231, or 97%, to $3,340,129 for the six months ended June 30, 2001 from $1,696,898 for the six months ended June 30, 2000. Workover expense was $0.38 per Mcfe for the six months ended June 30, 2001, an increase of 49% from $0.26 per Mcfe for the six months ended June 30, 2000. During the first half of 2000 and immediately preceding our bankruptcy filing, workover spending was minimized. During the remainder of 2000 and the first half of 2001, a workover program was completed that included normal and recurring workovers and a backlog of workovers from 1998 and 1999. During the first half of 2001, workover repairs were completed on several wells which will provide long-term cost savings due to a reduced requirement for minor maintenance work in the future and fewer interruptions from associated downtime. Production Taxes. Production taxes increased by $629,136 or 88% to $1,341,576 for the six months ended June 30, 2001 from $712,441 for the six months ended June 30, 2000. Production taxes were $0.15 per Mcfe for the six months ended June 30, 2001, an increase of 43% from $0.11 per Mcfe for the six months ended June 30, 2000. Increases in oil and natural gas production and revenues during the six months ended June 30, 2001 resulted in an increase in the amount of production taxes paid during the period. Depreciation, Depletion and Amortization Expense ("DD&A"). DD&A expense increased by $1,867,720, or 35%, to $7,262,042 for the six months ended June 30, 2001 from $5,394,322 for the six months ended June 30, 2000. DD&A was $0.83 per Mcfe for the six months ended June 30, 2001, an increase of 2% from $0.81 per Mcfe for the six months ended June 30, 2000. Increased oil and natural gas production during the six months ended June 30, 2001 resulted in an increase in the amount of depletion computed on those volumes. General and Administrative Expense ("G&A"). G&A increased $702,358, or 29%, to $3,149,231 for the six months ended June 30, 2001 from $2,446,873 for the six months ended June 30, 2000. G&A was $0.36 per Mcfe for the six months ended June 30, 2001, a decrease of 3% from $0.37 per Mcfe for the six months ended June 30, 2000. The increase was primarily the result of an increase in legal fees associated with non-bankruptcy legal matters for which the Company is primarily the plaintiff incurred during the first six months of 2001. Interest Expense. Interest expense decreased $457,000, or 7%, to $6,276,250 for the six months ended June 30, 2001 from $6,733,250 for the six months ended June 30, 2000. The decrease is primarily the result of the bankruptcy filing, and our decision during 2000 to accrue interest at 12% per annum, which was different from the stated rate of prime plus 4%. Reorganization Costs. Tri-Union Development Corporation filed a voluntary petition for relief under the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the Southern District of Texas, 40 Houston Division on March 14, 2000. As a result, we incurred certain reorganization costs totaling $7,311,108 for the six months ended June 30, 2001, a 699% increase from $914,809 for the six months ended June 30, 2000. These reorganization costs consist of the following: Professional fees and other - We were required to hire certain legal and accounting professionals to assist us and certain of our creditors with the bankruptcy proceedings. Retention - In an effort to maintain our employees through the bankruptcy period, we paid a retention bonus to our employees during the month of June 2001. Additional bank and refinancing charges - We incurred additional fees and costs associated with the payoff of our previous bank debt. Satisfaction of certain related party transactions - We entered into an agreement whereby we transferred to Atasca certain minor oil and gas properties owned by Tribo Petroleum Corporation and assigned to Atasca the net obligations owed to us by Richard Bowman. Additionally, we released Tribo Production Company, Ltd., BL Production Co., Ltd., and Atasca Properties, Ltd. from the net obligations they each owe to us. After giving effect to these transactions, all balances owing to and from us and these related parties is satisfied. Interest - Interest income has been recorded as an offset to reorganization costs as prescribed by SOP 90-7. The following table summarizes our reorganization costs incurred: <Table> <Caption> SIX MONTHS ENDED JUNE 30, ------------------------- 2000 2001 ---------- ------------ Professional fees and other................................. $956,463 $3,524,152 Retention bonus............................................. -- 301,740 Additional bank and refinancing charges..................... -- 1,754,750 Interest and amounts paid to creditors...................... -- 793,198 Satisfaction of certain related party transactions.......... -- 1,882,989 Interest income............................................. (41,654) (945,721) -------- ---------- Total reorganization costs........................ $914,809 $7,311,108 ======== ========== </Table> Hedging Contract. Upon the issuance of the senior secured notes, approximately 80% of our projected oil and natural gas production from proved developed producing reserves, and the basis differential attributable to approximately 80% of our projected proved developed producing natural gas production from our California properties, were hedged through May 31, 2003 at estimated net realized prices that we expect will exceed $4.50 per Mcf and $25.00 per Bbl, or a weighted natural gas-equivalent price of approximately $4.30 per Mcfe. In connection with the issuance of the notes, we have agreed to maintain, on a monthly basis, a rolling two-year hedge program until the maturity of the notes, subject to certain conditions. The estimated fair value of these hedge arrangements resulted in a net current asset of approximately $1,649,000 and a net non-current asset of approximately $1,937,000, with an offsetting amount of $3,586,000, recorded as other income. Provision for Income Taxes. A $391,441 provision for income tax was made for the six months ended June 30, 2001, primarily as a result of alternative minimum tax requirements. No provision for federal income tax was required for the six months ended June 30, 2000. Year Ended December 31, 2000 Compared to Year Ended December 31, 1999 For the year ended December 31, 2000, consolidated net loss was $5,786,026, a 37% decrease in the consolidated net loss of $9,150,034 for the year ended December 31, 1999. 41 Oil and Natural Gas Revenues. Oil and natural gas revenues increased $37,181,711, or 103%, to $73,452,054 for the year ended December 31, 2000 from $36,270,343 for the year ended December 31, 1999. The increase in oil and natural gas revenues was the result of an increase in production volumes as a consequence of a successful capital expenditure and workover program and an increase in the average price received for sales of oil and natural gas during the period. The following table summarizes the consolidated results of oil and natural gas production and related pricing for the years ended December 31, 2000 and 1999: <Table> <Caption> YEARS ENDED DECEMBER 31, ---------------------------- 1999 2000 % CHANGE ------- ------- -------- Oil production volumes (MBbls)........................ 1,145 1,333 16% Gas production volumes (MMcf)......................... 7,007 8,314 19 Total (MMcfe).................................... 13,874 16,313 18 Average oil price (per Bbl)........................... $ 17.27 $ 28.95 68% Average gas price (per Mcf)........................... 2.36 4.19 78 Per Mcfe......................................... 2.61 4.50 72 </Table> Gain on Marketable Securities. Gains on marketable securities were $995,180 for the year ended December 31, 2000. Certain marketable securities were bought and held principally for the purpose of selling them in the near term and are classified as trading securities. Trading securities are recorded at fair value on the balance sheet as current assets, with the change in fair value recognized during the period included in earnings. Other Income. Other income decreased $1,466,989, or 98%, to $28,404 for the year ended December 31, 2000 from $1,495,393 for the year ended December 31, 1999. The decrease was primarily the result of a change in accounting method for the year ended December 31, 2000, by which interest income was recorded as an offset to reorganization costs in accordance with SOP 90-7 and the non-recurring revision of prior year estimated accruals in 1999. Lease Operating Expenses. Lease operating expenses increased $3,943,082, or 25%, to $19,485,359 for the year ended December 31, 2000 from $15,542,277 for the year ended December 31, 1999. Lease operating expense was $1.19 per Mcfe for the year ended December 31, 2000, an increase of 6% from $1.12 per Mcfe for the year ended December 31, 1999. The increase was primarily the result of a general increase in oilfield related service costs, with the increase on a per unit of production basis partially offset by increases in production. Additionally, several non-recurring expenditures associated with returning over 50 wells to production at our Hastings, Sour Lake and AWP fields, the installation of an Amine unit and compressor at our Word field and regulatory compliance and compressor installations at several offshore locations contributed to the increase in lease operating expenses for the year ended December 31, 2000. Workover Expense. Workover expense increased $4,238,664, or 176%, to $6,649,074 for the year ended December 31, 2000 from $2,410,410 for the year ended December 31, 1999. Workover expense was $0.41 per Mcfe for the year ended December 31, 2000, an increase of 141% from $0.17 per Mcfe for the year ended December 31, 1999. In 2000, a workover program was completed that included normal recurring workovers, a backlog of workovers from 1998 and 1999 and workovers associated with certain of the 50 wells that we returned to production during the year. Expenses also included artificial lift and saltwater disposal system installations for certain wells in our Hastings, AWP, Ord Bend and Powderhorn fields. Production Taxes. Production taxes increased $1,263,487, or 179%, to $1,968,342 for the year ended December 31, 2000 from $704,855 for the year ended December 31, 1999. Production taxes were $0.12 per Mcfe for the year ended December 31, 2000, an increase of 140% from $0.05 per Mcfe for the year ended December 31, 1999. Production taxes are computed by multiplying produced volumes or revenues by a tax rate specified by the taxing authority. The taxing authorities, upon meeting certain conditional requirements, offered drilling and development incentives in the 42 form of tax rate reductions over a specified period of time. Certain of these incentives expired during early 2000, resulting in an increase in tax rates for the remainder of that year. Increases in oil and natural gas volumes and revenues during the year ended December 31, 2000 also contributed to the increase in the amount of production taxes paid during the period. Depreciation, Depletion and Amortization Expense. DD&A increased $2,466,442, or 22%, to $13,506,477 for the year ended December 31, 2000 from $11,040,035 for the year ended December 31, 1999. DD&A was $0.83 per Mcfe for the year ended December 31, 2000, an increase of 4% from $0.80 per Mcfe for the year ended December 31, 1999. An increase in oil and natural gas volumes produced during the year ended December 31, 2000 resulted in an increase in the amount of depletion computed on those volumes. DD&A per unit of production remained relatively steady as a result of increased production and reserves from the successful completion of a relatively low cost development program. General and Administrative Expense. G&A decreased $908,375, or 17%, to $4,328,358 for the year ended December 31, 2000 from $5,236,733 for the year ended December 31, 1999. G&A was $0.27 per Mcfe for the year ended December 31, 2000, a decrease of 29% from $0.38 per Mcfe for the year ended December 31, 1999. The decrease was primarily the result of a reversal of a provision for doubtful accounts, which had been recorded for a receivable owed by a working interest owner at December 31, 1999. A settlement agreement with the working interest owner during 2000 lead to the reversal of the provision for the account. Certain reorganization efforts and cost saving measures were implemented which also contributed to the decrease in G&A expenses for the period. Interest Expense. Interest expense increased $776,403, or 6%, to $12,757,863 for the year ended December 31, 2000 from $11,981,460 for the year ended December 31, 1999. The increase was primarily the result of an increase in outstanding borrowings. Reorganization Costs. Tri-Union Development Corporation filed for bankruptcy protection on March 14, 2000. We incurred reorganization costs of $21,487,191 for the year ended December 31, 2000. Reorganization costs primarily included the following: Rejection of fixed-price physical delivery contract -- The bankruptcy court approved a motion to reject a fixed-price physical delivery contract. A claim was filed by the damaged party resulting in a liability of $17,559,272. The contract was not a financial instrument that would qualify to be treated as a hedge for financial reporting purposes, accordingly the full amount of the claim was recorded as an expense for the year ended December 31, 2000. The full amount of the claim was satisfied in accordance with our amended plan of reorganization. Professional fees and other -- We retained certain legal and accounting professionals to assist with the bankruptcy proceedings and have incurred or estimated legal and accounting fees associated with these proceedings totaling $3,611,760 for the year ended December 31, 2000. Employee retention costs -- In an effort to maintain employees through the bankruptcy period, we sought approval from creditors and the bankruptcy court to compensate the employees when certain conditions are met. For the year ended December 31, 2000, estimated retention expenses of $855,000 were recorded. Interest -- Interest income of $538,841 was earned from March 14, 2000 through December 31, 2000. As prescribed by SOP 90-7, interest earned is off-set against reorganization costs, as described above. Provision for Income Taxes. A $79,000 provision for income tax was made for the year ended December 31, 2000, primarily as a result of alternative minimum tax considerations. No provision for federal income tax was required for the year ended December 31, 1999. 43 Year Ended December 31, 1999 Compared to Year Ended December 31, 1998 Effective March 31, 1998, we purchased certain oil and gas properties from Apache for $63,000,000. The results of operations for the year ended December 31, 1998 include oil and natural gas revenue and related costs associated with the properties acquired from Apache from the effective date of the acquisition. For the year ended December 31, 1999, consolidated net loss was $9,150,034, a 42% decrease in the consolidated net loss of $15,795,085 for the year ended December 31, 1998. Oil and Natural Gas Revenues. Oil and natural gas revenues increased $10,433,447, or 40%, to $36,270,343, for the year ended December 31, 1999, from $25,836,896 for the year ended December 31, 1998. The increase in oil and natural gas revenues was primarily the result of the receipt of a full 12 months of revenue from the properties acquired from Apache on March 31, 1998. Additionally, the average prices received for oil and natural gas production during the year ended December 31, 1999 were an average of $0.61 per Mcfe greater than for the year ended December 31, 1998. The following table summarizes the consolidated results of oil and natural gas production and related pricing for the years ended December 31, 1999 and 1998: <Table> <Caption> YEARS ENDED DECEMBER 31, ---------------------------- 1998 1999 % CHANGE ------- ------- -------- Oil production volumes (MBbls)....................... 1,030 1,145 11% Natural gas production volumes (MMcf)................ 6,711 7,007 4 Total (MMcfe)................................... 12,890 13,874 8 Average oil price (per Bbl).......................... $ 12.43 $ 17.27 39% Average natural gas price (per Mcf).................. 1.94 2.36 22 Per MMcfe....................................... 2.00 2.61 31 </Table> Other Income. Other income increased $952,749, or 176%, to $1,495,393 for the year ended December 31, 1999 from $542,644 for the year ended December 31, 1998. The increase is primarily the result of sales of emissions reduction credits and a revision of estimates of prior year expenses. Lease Operating Expenses. Lease operating expenses decreased $1,907,811, or 11%, to $15,542,277 for the year ended December 31, 1999 from $17,450,088 for the year ended December 31, 1998. Lease operating expense was $1.12 per Mcfe for the year ended December 31, 1999, a decrease of 17% from $1.35 per Mcfe for the year ended December 31, 1998. This decrease was primarily the result of efforts to shut-in production on uneconomical wells during the low commodity price period that began in 1998 and continued into 1999. Wells that were shut-in during 1999 were not brought back into production during 1999. Workover Expense. Workover expenses increased $1,810,720, or 302%, to $2,410,410 for the year ended December 31, 1999 from $599,690 for the year ended December 31, 1998. Workover expense was $0.17 per Mcfe for the year ended December 31, 1999, an increase of 240% from $0.05 per Mcfe for the year ended December 31, 1998. The increase was primarily the result of a workover program begun in late 1998 and continued during 1999 that we implemented on properties we purchased from Apache. Through July 1998, Apache continued to operate the properties we purchased on March 31, 1998. As a result, we commenced the workover program in late 1998, with 1999 being the first full year of workover activity on these properties. Production Taxes. Production taxes increased by $65,900, or 10%, to $704,855 for the year ended December 31, 1999 from $638,955 for the year ended December 31, 1998. Production taxes were $0.05 per Mcfe for the years ended December 31, 1999 and 1998. Increases in oil and natural gas production during the year ended December 31, 1999 resulted in an increase in the amount of production taxes paid, offset on a unit of production basis by the increase. Depreciation, Depletion and Amortization Expense. DD&A decreased by $1,357,765, or 11% to $11,040,035 for the year ended December 31, 1999 from $12,397,800 for the year ended 44 December 31, 1998. DD&A was $0.80 per Mcfe for the year ended December 31, 1999, a decrease of 17% from $0.96 per Mcfe for the year ended December 31, 1998. The decrease is attributable to increased reserve volumes apportioned to certain oil and gas properties at December 31, 1999, decreasing the rate at which those properties were depleted. General and Administrative Expense. G&A increased by $1,909,986, or 57%, to $5,236,733 for the year ended December 31, 1999 from $3,326,747 for the year ended December 31, 1998. G&A was $0.38 per Mcfe for the year ended December 31, 1999, an increase of 46% from $0.26 per Mcf for the year ended December 31, 1998. The increase is the result of our acquisition of the Apache properties and the increased overhead and operations expense associated with our assumption of the operations and administration of those properties on August 31, 1998. Interest Expense. Interest expense increased $4,247,529, or 55%, to $11,981,460 for the year ended December 31, 1999 from $7,733,931 for the year ended December 31, 1998. The increase was the result of our acquisition of the properties from Apache, which increased our outstanding debt by $63,000,000 in 1998. LIQUIDITY AND CAPITAL RESOURCES In March 1998, Tri-Union Development Corporation acquired certain onshore Texas oil and natural gas properties from Apache Corporation. Prior to the acquisition, we had approximately $35 million in debt outstanding. We incurred approximately another $63 million in debt in connection with the acquisition. We utilized funds from a short-term, amortizing bank loan in connection with the acquisition of Reunion. In August 1998, before we were able to refinance our bank loan, commodity prices began falling, with oil prices ultimately reaching a 12-year low in December of that year. The resultant negative effect on our cash flow from the deterioration of commodity prices, coupled with the required amortization payment on our bank loan, severely restricted the amount of capital we were able to dedicate to development drilling. Consequently, our oil and natural gas production declined, further negatively affecting our cash flow. In October 1998, our short-term loan matured and we arranged a forbearance agreement providing for interest payments to be partially capitalized and providing us with additional time to refinance our obligations. In July 1999, this forbearance agreement terminated and we made negotiated interest payments while attempting to negotiate a restructuring of our obligations. By March 2000, the aggregate principal balance of our bank debt had increased as a result of capitalized interest and expenses to approximately $105 million. In February 2000, the bank declared a default on the loan, demanded payment of all principle and interest and posted the shares of Tribo Petroleum Corporation, our parent corporation and a guarantor of the loan, for foreclosure. As a consequence of the bank's foreclosure action, on March 14, 2000, we filed for bankruptcy protection. After the filing, we operated as a "debtor-in-possession," continuing in possession of our estate, the operation of our business and the management of our properties. Under Chapter 11, certain claims against us in existence prior to the filing of the petition were stayed from enforcement or collection. These claims are reflected in full in the consolidated December 31, 2000 and June 30, 2001 balance sheets as "pre-petition liabilities subject to compromise." We filed our amended plan of reorganization in the bankruptcy court on May 9, 2001. Our plan was confirmed by a court order entered as of May 23, 2001, subject to the completion of the original offering of the old notes and class A common stock. On June 18, 2001, the original offering closed and we exited bankruptcy. The proceeds of the offering and our available cash balances at closing were sufficient to allow us to pay or segregate funds for the payment of all claims. At June 30, 2001, we had $130.0 million of debt. Our significant leverage creates certain risks, as set forth under the heading "Risk Factors -- Our significant leverage and lack of capital resources may affect our ability to successfully operate and service our debt obligations." During the six months ended June 30, 2001, our cash balances decreased by $20,025,189 to $12,964,750 from $32,989,939 for the year ended December 31, 2001. 45 Net cash used by operating activities before reorganization costs was $19,739,547 for the six months ended June 30, 2001. The increase is the result of a decrease in accounts payable, accounts receivables and prepaid expenses for the six months ended June 30, 2001. Additionally, we deposited $13,566,895 into restricted cash as required by our plan of reorganization to satisfy the payment in full of all remaining disputed pre-petition claims. These uses of cash were partially offset by an increase in net income of $19,180,647 after reorganization costs of $7,311,108 and income from hedging contract of $3,586,626 for the six months ended June 30, 2001, when compared to net income of $2,806,530 after reorganization costs of $914,809 for the six months ended June 30, 2000. Net cash used in investing activities was $1,977,850 for the six months ended June 30, 2001 when compared to $2,854,514 for the six months ended June 30, 2000. The decrease is primarily the result of an increase in proceeds from the sales of oil and natural gas properties of $1,844,029, to $2,225,529 for the six months ended June 30, 2001 from $381,500 for the six months ended June 30, 2000. Additionally, proceeds from the sale of marketable securities decreased $1,181,668 to $236 for the six months ended June 30, 2001 from $1,181,904 for the six months ended June 30, 2000. Net cash provided by financing activities was $6,566,408 for the six months ended June 30, 2001 when compared to net cash used of $668,673 for the six months ended June 30, 2000. The increase is the result of the completion of the senior notes offering on June 18, 2001 resulting in our exit from bankruptcy. The net cash proceeds from the offering provided sufficient available cash, allowing us to pay or segregate funds for the payment of all claims. During the years ended December 31, 2000 and 1999, we used $10,117,790 and $11,943,495, respectively, in investment activities. We deposited $355,000 during the year ended December 31, 2000, as compared to $3,664,957 during the year ended December 31, 1999, into restricted cash accounts for future plugging and abandonment liabilities. Additionally, we reduced our investments in property development by $2,694,787 to $10,877,657 for the year ended December 31, 2000 as compared to $13,572,444 for the year ended December 31, 1999. However, when we include amounts expensed for workovers during these periods, we increased amounts expensed for workovers and development costs to $16.7 million and $15.7 million for the years ended December 31, 2000 and 1999, respectively, from $10.1 million for the year ended December 31, 1998. The following table sets forth information concerning our oil and natural gas property acquisition, exploration and development activities and the related costs during the year's ended December 31, 1998, 1999 and 2000 and the six months ended June 30, 2001: <Table> <Caption> SIX MONTHS YEAR ENDED DECEMBER 31, ENDED --------------------------- JUNE 30, 1998 1999 2000 2001 ------- ------- ------- ---------- (IN THOUSANDS) Property acquisition -- proved............ $62,477 $ 250 $ 408 $ -- Development costs......................... 9,515 13,322 10,080 3,339 Exploration costs......................... -- -- 389 -- ------- ------- ------- ------ Total costs incurred............ $71,922 $13,572 $10,878 $3,339 ======= ======= ======= ====== </Table> For the years ended December 31, 2000 and 1999, net cash used in financing activities was $401,047 and $42,314, respectively. The increase was the result of the financing of certain well control insurance policies in 1999. 46 CAPITAL REQUIREMENTS Historically, our principal sources of capital have been cash flow from operations, short-term reserve-based bank loans, private placement units, and proceeds from asset sales. Our principal uses for capital have been the acquisition and development of oil and natural gas properties. At June 30, 2001, our cash balance was $13.0 million. Our budget for 2001 will include capital expenditures of $17.1 million, representing an increase of 57% over our total capital expenditures for 2000. We expect to use approximately $14.6 million of this amount for development drilling and recompletions, approximately $1.7 million to conduct two 3-D seismic surveys over certain leases in California and $0.8 million for other geological and geophysical expenditures. In addition, we are currently evaluating 24 behind pipe opportunities in the Sacramento Basin that were not classified as proved at December 31, 2000. These projects may be added to our budgeted projects during the remainder of 2001 depending on our capital resources. We anticipate we may expend an additional $720,000 in 2001 should we decide to fund these 24 projects. Further, depending on our capital resources we may substitute some of these projects for currently budgeted projects as these behind pipe opportunities are less expensive than many of our budgeted development projects. Qualitative Disclosures About Market Risk Revenues from our operations are highly dependent on the price of oil and natural gas. The markets for oil and natural gas are volatile and prices for oil and natural gas are subject to wide fluctuations in response to relatively minor changes in the supply of and demand for oil and natural gas and a variety of additional factors that are beyond our control, including the level of consumer demand, weather conditions, domestic and foreign governmental regulations, market uncertainty, the price and availability of alternative fuels, political conditions in the Middle East, foreign imports and overall economic conditions. It is impossible to predict future oil and natural gas prices with any certainty. To reduce our exposure to oil and natural gas price risks, from time to time we may enter into commodity price derivative contracts to hedge commodity price risks. Approximately 80% of our projected oil and natural gas production from proved developed producing reserves (and the basis differential attributable to approximately 80% of our projected proved developed producing natural gas production from our California properties) are hedged through June 30, 2003 at swap prices of $4.19 per Mcf and $25.30 per Bbl, or a weighted-average natural gas-equivalent price of approximately $4.20 per Mcfe. In connection with the issuance of the old notes, we agreed to maintain, on a monthly basis, a rolling two-year hedge program until the maturity of the old notes and the new notes, subject to certain conditions. Recently Issued Accounting Pronouncements In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133 ("FAS 133"), "Accounting for Derivative Instruments and Hedging Activities." FAS 133, as amended by FAS 137, is effective for transactions entered into after June 15, 2000. FAS 133 requires that all derivative instruments be recorded on the balance sheet at fair value. Changes in the fair value of derivatives are recorded for each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. The ineffective portion of all hedges will be recognized in earnings. The adoption of FAS 133 on January 1, 2001 did not have a significant impact on the financial statements; however it may have a significant impact in the future. In December 1999, the SEC issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements." SAB 101 outlines the basic criteria that must be met to recognize revenue and provides guidance for disclosure related to revenue recognition policies. In June 2000, the SEC issued SAB 101B that delayed the implementation date of SAB 101 until the quarter ended December 31, 2000, with retroactive application to the beginning of our fiscal year. 47 The adoption of SAB 101 did not have a material impact on our financial position or results of operations. In March 2000, the Financial Accounting Standards Board issued interpretation No. 44, "Accounting for Certain Transactions Involving Stock Compensation -- An interpretation of APB No. 25" ("FIN 44"). FIN 44 clarified the application of Opinion No. 25 in certain respects, including; the definition of "employee" for purposes of applying Opinion No. 25; the criteria for determining whether a plan qualifies as a non-compensatory plan; the accounting consequences of various modifications to the terms of a previously fixed stock option or award; and the accounting for an exchange of stock compensation awards in a business combination. In general, FIN 44 became effective July 1, 2000. The adoption of FIN 44 did not have a material impact on our financial position or results of operation. In June 2001, the Financial Accounting Standards Board finalized FASB Statements No. 141, Business Combinations (SFAS 141), and No. 142, Goodwill and Other Intangible Assets (SFAS 142). SFAS 141 requires the use of the purchase method of accounting and prohibits the use of the pooling-of-interests method of accounting for business combinations initiated after June 30, 2001. SFAS 141 also required that the Company recognize acquired intangible assets apart from goodwill if the acquired intangible assets meet certain criteria. SFAS 141 applies to all business combinations initiated after June 30, 2001 and for purchase business combinations completed on or after July 1, 2001. It also requires, upon adoption of SFAS 142 that the Company reclassify the carrying amounts of intangible assets and goodwill based on the criteria in SFAS 141. SFAS 142 requires, among other things, that companies no longer amortize goodwill, but instead test goodwill for impairment at least annually. In addition, SFAS 142 requires that the Company identify reporting units for the purposes of assessing potential future impairments of goodwill, reassess the amortization of intangible assets with an indefinite useful life. An intangible asset with an indefinite useful life should be tested for impairment in accordance with SFAS 142. SFAS 142 is required to be applied in fiscal years beginning after December 15, 2001 to all goodwill and other intangible assets recognized at that date, regardless of when those assets were initially recognized. SFAS 142 requires the Company to complete a transitional goodwill impairment test six months from the date of adoption. The Company is also required to reassess the useful lives of other intangible assets within the first interim quarter after adoption of SFAS 142. Currently, the Company is assessing but has not yet determined how the adoption of SFAS 141 and SFAS 142 will impact its financial position and results of operations. 48 BUSINESS AND PROPERTIES THE COMPANY We are an independent oil and natural gas company engaged in the acquisition, development, exploration and production of oil and natural gas properties in three core areas. Our core areas are located onshore Gulf Coast, primarily in Texas and Louisiana, offshore Gulf Coast in the shallow waters of the Gulf of Mexico and in the Sacramento Basin of northern California. We have established significant operating expertise in our core areas and, since 1999, have achieved substantial production growth with a limited capital budget. We have one subsidiary, Tri-Union Operating Company, which is wholly owned by us. Tri-Union Operating's principal asset is a net profits interest in a field operated by us. This interest is the only oil and natural gas property of Tri-Union Operating and represents less than 5% of our consolidated proved reserves. At December 31, 2000, we had net proved reserves of 180.1 Bcfe, approximately one-half of which were natural gas, with a reserve life of 11.0 years. Our reserve base is diversified across our three core areas, with 64% of our proved reserves located onshore Gulf Coast, 12% offshore Gulf Coast and 24% in California. Each of these core areas are characterized by years of stable, historical production and numerous producing wells. We operate approximately 92% of our proved reserves. We have a significant presence in the Gulf Coast Basin. As of December 31, 2000, we owned interests in 44 fields located onshore Gulf Coast and owned interests in 33 producing blocks offshore Gulf Coast, representing over 172,000 gross acres. In the first half of 2001, these fields produced approximately 37 MMcfe per day. We also have a significant presence in the Sacramento Basin. As of December 31, 2000, we owned interests in 16 fields representing over 65,000 gross acres in the Sacramento Basin. In the first half of 2001, these fields produced approximately 10 MMcfe per day. We have a large inventory of development projects that we have only recently begun to exploit. Because we operate in older, more mature fields with long production histories and many producing wells, we believe these projects represent low-risk opportunities to add to our reserves. We completed 28 of these projects during 1999 and 2000 for $10.6 million in development capital expenditures for drilling and recompletions, resulting in a 42% increase in our daily production. We experienced a 75% drilling success rate over that period. We have identified another 175 similar projects on our existing fields to pursue through 2003. Of these projects, 116 are proved behind pipe and proved undeveloped projects and two are 3-D seismic surveys in California. We have allocated $14.9 million of our capital budget for the second half of 2001, $19.3 million for 2002 and $3.5 million for 2003 for these projects. The balance of 57 projects are behind pipe opportunities in the Sacramento Basin that were not classified as proved at December 31, 2000. Of these projects, 24 and 33 may be added to our budgeted projects during 2001 and 2002, respectively, depending on our capital resources. We anticipate that we may expend an additional $720,000 during the remainder of 2001 and $990,000 in 2002 should we decide to fund these projects. Further, depending on our capital resources, we may substitute some of these projects for currently budgeted projects as these behind pipe opportunities are less expensive than many of our budgeted development projects. From June through December 2001, we expect to drill 23 development wells, conduct 3 sidetrack/deepening and stimulation projects of existing wells and acquire approximately 28 square miles of 3-D seismic data over certain of our Sacramento Basin properties. Approximately 80% of our projected oil and natural gas production from proved developed producing reserves (and the basis differential attributable to approximately 80% of our projected proved developed producing natural gas production from our California properties) is hedged through June 30, 2003 at swap prices of $4.19 per Mcf and $25.30 per Bbl, or a weighted-average natural gas-equivalent price of 49 approximately $4.20 per Mcfe. In connection with the issuance of the old notes, we agreed to maintain, on a monthly basis, a rolling two-year hedge program until the maturity of the old notes and the new notes, subject to certain conditions. We believe this hedging program will provide us with the financial capacity to successfully execute our development plans and profitably grow production from current levels. We acquired our first significant reserves in 1996 with the Reunion acquisition and have grown substantially since that time. Since January 1997, our first full year following the Reunion acquisition, our reserves increased from 46.9 Bcfe to 180.1 Bcfe, representing a compound annual growth rate of 40% and an annual average reserves replacement rate of over 520%. Similarly, annual production increased from 2.0 Bcfe in 1996 to 16.3 Bcfe in 2000, representing a compound annual growth rate of 69%. EBITDA increased from $2.7 million in 1996 to $42.0 million in 2000, representing a compound annual growth rate of 99%. Since 1996 we have achieved growth profitably, investing $118.0 million in acquisition and drilling capital expenditures and generating 237.0 Bcfe of additional proved reserves. On July 27, 2001, we were the surviving corporation in a merger with our parent corporation, Tribo Petroleum Corporation. As a consequence of this merger, we assumed all of the rights and obligations of Tribo. OUR STRATEGY Our objective is to increase our cash flow and proved reserves through a balanced growth strategy focused on efforts to: Develop our large inventory of behind pipe and undeveloped projects. We plan to pursue 118 development and exploitation projects in our three core areas through 2003 for approximately $37.7 million in capital expenditures, as compared to 28 development drilling and recompletion projects completed in 1999 and 2000 for $10.6 million in capital expenditures. Our capital budget through 2003 will be focused on 69 development wells and proved behind pipe objectives onshore Gulf Coast, 10 proved behind pipe and proved undeveloped objectives offshore Gulf Coast and 39 proved undeveloped and behind pipe objectives and 3-D seismic surveys in California. We expect that over 66% of these projects will be natural gas focused. <Table> <Caption> FOR THE PERIOD JUNE 1, 2001 THROUGH DECEMBER 31, 2003 --------------------------- BUDGETED BUDGETED DEVELOPMENT COST AREA OF OPERATION PROJECTS (IN MILLIONS) ----------------- ----------- ------------- Onshore Gulf Coast.......................................... 69 $23.0 Offshore Gulf Coast......................................... 10 3.7 California.................................................. 39 11.0 --- ----- Total............................................. 118 $37.7 === ===== </Table> Additionally, we are currently evaluating 57 behind pipe opportunities in the Sacramento Basin that were not classified as proved at December 31, 2000. Of these projects, 24 and 33 may be added to our budgeted projects during 2001 and 2002, respectively, depending on our capital resources. We anticipate that we may expend an additional $720,000 during the remainder of 2001 and $990,000 in 2002 should we decide to fund these projects. Further, depending on our capital resources we may substitute some of these projects for currently budgeted projects as these behind pipe opportunities are less expensive than many of our budgeted development projects. Maintain our geographic focus and operating control. We will concentrate our activities in our onshore Gulf Coast, offshore Gulf and California areas, where 100% of our proved reserves were located at December 31, 2000. We believe that our region-specific geological, engineering and production experience allows us to maximize our reserve potential. Our operated properties currently 50 comprise approximately 92% of our proved reserves, allowing us to maintain control over the planning, incurrence and timing of many capital and operating expenditures. Our geographic focus and operating control should allow us to promptly implement our expanded capital budget and increase our core area development activity, which we expect will lead to additional increases in production and cash flow. Pursue selective acquisitions in our core areas. We plan to selectively acquire producing oil and natural gas properties in our core areas where we have or will assume operations. We believe there will continue to be attractive acquisition opportunities as major and large independent oil and natural gas companies continue to focus their resources away from smaller, lower-risk development opportunities in favor of higher-risk exploration opportunities internationally and in the deepwater Gulf of Mexico. Mitigate volatility in our cash flow through a prudent hedging program. We believe that current oil and natural gas prices are attractive, providing us with the opportunity to realize substantial value for our production. In connection with the issuance of the old notes, we agreed to maintain, on a monthly basis, a rolling two-year hedge program until the maturity of the old notes and the new notes, subject to certain conditions. We believe this hedging program will improve the predictability of our cash flow, add certainty to our rate of return on drilling activities and, in all but the worst price scenarios, cover our interest expense and required amortization payments while the notes are outstanding. Approximately 80% of our projected oil and natural gas production from proved developed producing reserves is hedged through June 30, 2003 at swap prices of $4.19 per Mcf and $25.30 per Bbl, or a weighted-average natural gas-equivalent price of approximately $4.20 per Mcfe. OUR BANKRUPTCY AND RECAPITALIZATION In March 1998, we acquired certain onshore Texas oil and natural gas properties from Apache Corporation. Prior to the acquisition, we had approximately $35 million in debt outstanding. We incurred approximately another $63 million in debt in connection with the acquisition. A portion of this debt was in the form of a short-term, amortizing bank loan. In August 1998, before we were able to refinance our bank loan, commodity prices began falling, with oil prices ultimately reaching a 12-year low in December 1998. The resultant negative effect on our cash flow from the deterioration of commodity prices, coupled with the required amortization payments on our bank loan, severely restricted the amount of capital we were able to dedicate to development drilling. Consequently, our oil and natural gas production declined, further negatively affecting our cash flow. In October 1998, our short-term loan matured and we arranged a forbearance agreement providing for interest payments to be partially capitalized and providing us additional time to refinance our obligations. In July 1999, the forbearance agreement terminated and we made negotiated interest payments while attempting to negotiate a restructuring of our obligations. By March 2000, the aggregate principal balance of our bank debt had increased as a result of capitalized interest and expenses to approximately $105 million. In February 2000, the bank declared a default on the loan, demanded payment of all principle and interest and posted the shares of Tribo Petroleum Corporation, our parent corporation and a guarantor of the loan, for foreclosure. As a consequence of the bank's foreclosure action, on March 14, 2000, we chose to seek protection under Chapter 11 of the Bankruptcy Code in U.S. Bankruptcy Court for the Southern District of Texas, Houston Division. Tri-Union Operating continued to operate outside of bankruptcy. As a result of the redeployment of funds formerly utilized for amortization payments, we have conducted a limited but highly successful development drilling program, which has resulted in an increase of approximately 42% of our average daily production over the last two years. This production increase, coupled with improved commodity prices, allowed us to increase our cash position to approximately $66.7 million immediately prior to closing of the offering of the old notes from approximately $1.4 million on March 14, 2000. The old notes were issued on June 18, 2001 as part of a private unit offering, with each unit consisting of one old note in the principal amount of $1,000 and one share of class A common stock of our former parent corporation, Tribo Petroleum 51 Corporation, with which we merged on July 27, 2001. The units were sold to Jefferies & Company, Inc., as initial purchaser. The initial purchaser sold the units to qualified institutional buyers in reliance on Rule 144A under the Securities Act. The proceeds of the offering of the old notes and our available cash balances allowed us to satisfy all creditor claims in full, including interest, in accordance with the amended plan of reorganization that we filed on May 9, 2001 and to exit bankruptcy on June 18, 2001. The old notes are our only material long-term indebtedness. Our level of indebtedness as of June 30, 2001, was $130.0 million as compared to adjusted EBITDA on a pro forma basis for the six months then ended of $36.8 million and for the year ended December 31, 2000, of $42.0 million. Our significant leverage creates risks for holders of the notes, including the risk that we will be unable to satisfy the amortization payments due on the notes on June 1, 2002, 2003 and 2004. See "Risk Factors -- Our significant leverage and lack of capital resources may affect our ability to successfully operate and service our debt obligations." OUR PRINCIPAL OIL AND NATURAL GAS PROPERTIES Our oil and natural gas properties are primarily located in three core areas of operation: (1) onshore Gulf Coast, primarily in Texas and Louisiana; (2) offshore Gulf Coast in the shallow waters of the Gulf of Mexico; and (3) in the Sacramento Basin of northern California. All of our oil and natural gas properties are subject to the lien of the indenture that secures the notes, as well as liens imposed by operation of law, such as mechanic's liens and liens for property taxes not yet due. None of our properties has an attached payment or performance obligation. Our onshore Gulf Coast properties accounted for 64% of our proved reserves at December 31, 2000 and 64% of our production for the six months ended June 30, 2001. At December 31, 2000, our onshore Gulf Coast proved reserves were distributed among 44 fields. These reserves are further distributed among approximately 370 producing wells and a number of undeveloped locations. Most of our onshore Gulf Coast producing wells have been on production for several years and their respective production decline rates are relatively slow and well established. Our working interests in the fields range from 0.16% to 100% with an average working interest of 70%. We operate 36 of our 44 fields in the onshore Gulf Coast area and nine of our 14 top value properties are located in the area. Each of these nine top value properties are operated by us and, in aggregate, accounted for approximately 82% of the area's production for the six months ended June 30, 2001 and 86% of our proved reserves in the area at the end of 2000. Our $8.5 million capital budget for the area during the remainder of 2001 includes 15 low-risk development projects targeting 13.5 Bcfe of proved undeveloped reserves. Our offshore Gulf Coast properties accounted for 12% of our proved reserves at December 31, 2000 and 15% of our production for the six months ended June 30, 2001. At December 31, 2000, our offshore Gulf Coast proved reserves were distributed among 33 fields. Our working interests in the fields range from 4.23% to 100% with an average working interest of 50%. We operate 22 of our 33 fields in the offshore Gulf Coast area and 61% of the proved reserves are developed. Additionally, the offshore Gulf Coast properties have 8.5 Bcfe proved undeveloped reserves which we intend to exploit through farm out and joint venture arrangements with industry partners. These farm out and joint venture arrangements will allow us to benefit from the reserve and cash flow potential of the projects without incurring the associated risks of significant capital investment. Recently, we have finalized farm out agreements covering two of our offshore Gulf Coast properties and we expect to have wells completed pursuant to those farm out agreements during 2001. Two of our 14 top value properties are located offshore Gulf Coast. These two properties accounted for approximately 4% of the production from the area for the six months ended June 30, 2001 and 39% of our proved reserves in the area at the end of 2000. Our California properties accounted for 24% of our proved reserves at December 31, 2000 and 21% of our production for the six months ended June 30, 2001. At December 31, 2000, our proved reserves in the area were distributed among 16 fields. The majority of these reserves are further 52 distributed among 137 producing wells and 22 undeveloped locations. Most of our producing wells in California benefit from long production histories and well established decline curves. Additionally, we have recently benefited from a net sales price for our natural gas production in this area that has exceeded NYMEX natural gas prices. Our working interests in California range from approximately 2.5% to 100% with an average working interest of 57%. We operate 12 of our 16 fields in the area. Three of our top value properties are located in California. We operate all three of these properties which account for approximately 32% of the production from the area for the six months ended June 30, 2001 and 82% of our proved reserves in the area at the end of 2000. Recently, we identified approximately 57 behind pipe objectives in existing wellbores that we believe represent significant reserve potential in addition to our proved reserves. We plan to conduct 3-D seismic surveys covering approximately 28 square miles of our leasehold during the last half of 2001. We anticipate that the 3-D seismic surveys will confirm specific locations for previously identified development prospects and may additionally yield opportunities to drill exploratory wells in our Grimes and Sutter City fields. Our $6.4 million capital budget for the area during the remainder of 2001 includes the 3-D seismic surveys and 11 low-risk development drilling projects targeting 13.9 Bcfe of proved undeveloped reserves. The following table and discussion provides proved reserves, PV-10 Values, first half production and descriptive information for our three core areas and the principal properties within each core area. These principal properties accounted for approximately 80% of our estimated proved reserves at December 31, 2000. These same properties accounted for 60% of our total oil and natural gas production in the first half of 2001, which averaged 47 MMcfe per day. <Table> <Caption> NET PROVED % OF NET RESERVES % OF NET PROVED FIELD (MMCFE) PV-10 VALUE(1) PRODUCTION(2) RESERVES(1) ----- ---------- -------------- ------------- ------------ (IN THOUSANDS) Onshore Gulf Coast: Hastings Complex............... 52,873 $ 53,561 25.9% 29.4% Constitution................... 11,684 60,348 14.2 6.5 Word........................... 7,405 36,140 1.1 4.1 AWP............................ 7,189 32,112 2.0 4.0 Clear Branch................... 5,470 28,324 1.0 3.0 Sour Lake...................... 5,192 8,829 2.4 2.9 Scott.......................... 3,063 22,095 3.1 1.7 North Alvin.................... 3,031 7,984 1.0 1.7 South Liberty.................. 2,708 6,654 2.2 1.5 Other.......................... 15,972 42,928 11.5 8.8 ------- -------- ----- ----- Subtotal............... 114,587 298,975 64.4 63.6 Offshore Gulf Coast: South Pass 27.................. 5,542 14,325 0.4 3.1 Eugene Island 277.............. 3,077 11,543 0.2 1.7 Other.......................... 13,274 75,622 14.2 7.4 ------- -------- ----- ----- Subtotal............... 21,893 101,490 14.8 12.2 California: Sutter Buttes.................. 28,493 153,391 3.1 15.8 Grimes......................... 4,155 21,457 2.9 2.3 Greeley........................ 3,344 7,939 0.6 1.9 Other.......................... 7,665 46,750 14.2 4.2 ------- -------- ----- ----- Subtotal............... 43,657 229,537 20.8 24.2 ------- -------- ----- ----- Total.................. 180,137 $630,002 100.0% 100.0% ======= ======== ===== ===== </Table> --------------- (1) Based on our PV-10 Value and proved reserve estimates as of December 31, 2000. (2) For the six months ended June 30, 2001. 53 Onshore Gulf Coast Hastings Complex. The Hastings Complex includes three fields, encompasses approximately 8,800 acres and is located approximately 30 miles south of Houston in Brazoria County, Texas. In March 1998 we acquired working interests in the three fields ranging from 68.3% to 100%. The fields produce from multiple Miocene and Frio reservoirs at depths ranging from 2,000 feet to 7,000 feet. At the time of our acquisition, the fields had produced in excess of 682 MMBbls and 259 Bcf since discovery in 1934 by Stanolind Oil and Gas Co. Production from the fields was approximately 11,808 Mcfe per day and net operating cash flow was approximately $357,000 per month. Since assuming operations in August 1998, we have increased production and reduced operating expenses in the field. The increased production and reduced operating expenses, combined with higher commodity prices, have resulted in a 268% increase in the field's operating cash flow. We were able to achieve this increase with minimal capital investment by re-engineering the field's artificial lift system, exploiting behind pipe opportunities and eliminating uneconomic wells. Net daily production from the Hastings Complex during the first half of 2001 averaged 12,257 Mcfe and at December 31, 2000 we had proved reserves of 52,873 MMcfe. During the remainder of 2001 we intend to continue our production and cost optimization efforts and drill one proved undeveloped location. Constitution Field. In March 1998 we acquired our working interests in the Constitution field, which is located in Jefferson County, Texas. Our working interests range from 25.0% to 100.0%. The field produces from the Yegua reservoir at depths ranging from 13,500 feet to 15,011 feet. As of the date we assumed operations, the net daily production from the field was approximately 339 Mcfe. In the second quarter of 2000 we recompleted our Westbury Farms #1 well to the Yegua Sand and then fracture stimulated the reservoir. Initial net production after stimulation was approximately 10,013 Mcfe per day. Our success in the Westbury Farms #1 resulted in reserve additions from four additional proved undeveloped locations. Net daily production from the Constitution field during the first half of 2001 was 6,730 Mcfe and at December 31, 2000 we had proved reserves of 11,684 MMcfe. During the remainder of 2001 we intend to drill two proved undeveloped locations. Word Field. The Word field is located in Lavaca County, Texas and produces from the Lower Wilcox and Edwards Limestone reservoirs at depths from 8,100 feet to 13,200 feet. In March 1998 we acquired working interests that range from 87.5% to 100.0%. At the time of our acquisition, the field had produced over 47 Bcfe since its discovery in 1944 and was then producing at a net daily rate of 702 Mcfe per day. Net daily production from the field during the first half of 2001 averaged 523 Mcfe per day and at December 31, 2000 we had proved reserves of 7,405 MMcfe, including reserves from one proved behind pipe objective and five proved undeveloped Edwards locations. During the remainder of 2001 we intend to drill one development well targeting proved undeveloped reserves in the Edwards Limestone. Additionally, we plan to drill one or more of the Edwards locations horizontally in order to maximize ultimate recoveries. AWP Field. Our interest in the AWP field is comprised of a working interest covering 5,144 acres in McMullen County, Texas. The field produces from the Olmos and Wilcox reservoirs at depths ranging from 5,775 feet to 8,950 feet. In March 1998 we acquired the working interests in the field, which range from 97.2% to 100.0%. At the time of our acquisition, the field had produced over 430 Bcfe since its discovery in 1981. Net daily production from the field during the first half of 2001 averaged approximately 963 Mcfe and we had proved reserves of 7,189 MMcfe at December 31, 2000, including reserves attributable to eight proved undeveloped locations. During recent years, the field has experienced a resurgence of activity by other operators due to advances in fracture stimulation technology. Consequently, we believe that significant low-risk drilling opportunities exist on our acreage that we intend to exploit. We plan to utilize these fracture stimulation technologies to exploit our existing inventory of eight proved undeveloped locations and other potential locations on our acreage. During the remainder of 2001 we intend to drill one such development well. 54 Clear Branch Field. We acquired our working interests in the Clear Branch field in July 1997. We operate the two active wells in the field and our working interests range from 84.4% to 99.0%. The field produces from the Hosston reservoir at depths ranging from 9,700 to 9,900 feet. Net daily production from the field during the first half of 2001 averaged approximately 451 Mcfe and we had proved reserves of 5,470 MMcfe at December 31, 2000, including reserves attributable to two proved undeveloped locations that we intend to drill in 2001. Additional proved reserves are attributable to one behind pipe objective that will be completed following depletion of the current producing intervals. We also plan to fracture stimulate one of the producing wells during 2001. Sour Lake Field. The Sour Lake field, discovered in 1902, is the second oldest field in Texas. It is located 15 miles west of Beaumont, Texas in Hardin County and produces from the Miocene, Frio and Yegua reservoirs at depths ranging from 800 feet to 7,577 feet. Our acreage was acquired from Apache in March 1998. Apache had acquired the acreage from Texaco, which discovered the field. We own 100% of the working interests and mineral estate in fee under 930 acres in the field. Our largest contiguous lease position in the field, 815 acres, is situated over the structural high and is the field's most prolific area. Net daily production from the field during the first half of 2001 averaged approximately 1,115 Mcfe and we had proved reserves of 5,192 MMcfe at December 31, 2000, including reserves attributable to five proved behind pipe objectives and ten proved undeveloped locations. We plan to drill three of the proved undeveloped locations and recomplete two behind pipe objectives in 2002. Scott Field. The Scott field is located in Lafayette Parish, Louisiana and produces from the Stutes and Bol Mex reservoirs at depths ranging from 11,500 feet to 15,200 feet. We acquired our working interests, which range from 13.2% to 27.4% in June 1997. The field had been on production since the 1980's and recovered 8.0 Bcfe, but had never been exploited with the benefit of modern 3-D seismic data and production had declined to 633 Mcfe per day. In the fourth quarter of 1999, after completing a 3-D seismic evaluation, we drilled the Falcon #2 and completed the well in the Bol Mex V reservoir. Net daily production from the field during the first half of 2001 averaged approximately 1,468 Mcfe and we had proved reserves of 3,063 MMcfe at December 31, 2000, including reserves attributable to one proved behind pipe objective and one proved undeveloped location. Additional potential exists in two step-out drilling locations that are based upon 3-D seismic surveys. During 2001, our capital budget provides $275,000 for deepening the Falcon #1 to recover proved undeveloped reserves of 1.1 Bcfe. North Alvin Field. In 1996, as part of the Reunion acquisition, we acquired working interests ranging from 34.3% to 41.6% in the North Alvin field, located in Brazoria County, Texas. The field produces from Frio sandstones at depths ranging from 7,900 feet to 8,600 feet. At the time of our acquisition the field had produced over 28.4 Bcfe. Net daily production from the field during the first half of 2001 averaged approximately 465 Mcfe and we had proved reserves of 3,031 MMcfe at December 31, 2000. The proved reserves in the field include undeveloped reserves attributable to four reservoirs that we believe can be accessed by one wellbore, scheduled to be drilled during 2001. South Liberty Field. The South Liberty field is located 35 miles east of Houston in Liberty County, Texas. We own a 100% working interest in the field. We acquired our interest in South Liberty in March 1998 and at the time of the acquisition the field had produced over 632 Bcfe since its discovery in 1925. The field produces from Miocene, Frio, Yegua and Cook Mountain reservoirs at depths ranging from 1,500 feet to 11,000 feet. Net daily production from the field during the first half of 2001 averaged approximately 1,028 Mcfe and we had proved reserves of 2,708 MMcfe at December 31, 2000. Offshore Gulf Coast South Pass 27 Field. In 1997, we acquired non-operating working interests ranging from 27% to 41% in the South Pass 27 field from Statoil. The field is located in federal waters offshore 55 Louisiana in approximately 120 feet of water. Net daily production from the field during the first half of 2001 averaged approximately 201 Mcfe and we had proved reserves of 5,542 MMcfe at December 31, 2000. The proved reserves in the field include undeveloped reserves attributable to six reservoirs. Eugene Island 277 Field. We acquired a 100% working interest in the Eugene Island 277 field in 1997. The field is located in federal waters offshore Louisiana in approximately 300 feet of water. Net daily production from the field during the first half of 2001 averaged approximately 83 Mcfe and we had proved reserves of 3,077 MMcfe at December 31, 2000. California Sutter Buttes Field. Our largest contiguous operation is in the Sutter Buttes field in northern California, located approximately 40 miles north of Sacramento in Sutter and Colusa Counties. Our working interests range from 53.2% to 85.5%. The Sutter Buttes field is comprised of over 43,000 contiguous gross acres of leasehold with approximately 62 producing wells, which we operate. At December 31, 2000 we owned 38,000 net acres in the field. We have extensive operating expertise in this area and significant experience with the Forbes and Kione reservoirs. From November 1998 to February 2000, we drilled 10 development wells targeting the Forbes and Kione reservoirs at depths of 3,100 feet to 7,100 feet. Nine of the wells were successful and resulted in significant increases in our production and cash flow. Our net daily production during the first half of 2001 averaged 1,469 Mcfe and our proved reserves at December 31, 2000 were 28,493 MMcfe. Our planned capital budget for the remainder of 2001 provides $4.2 million to drill ten development wells targeting the Forbes reservoir and 11.5 Bcf of proved undeveloped reserves. Additionally, we plan to survey six square miles in the Sutter City leases with 3-D seismic. The Sutter City leases have produced from the Kione sand, but the Sutter City wells have not tested the deeper Forbes interval that has been prolific on our adjacent acreage. Grimes Field. Our Grimes field, also acquired in 1996, is located to the southwest of Sutter Buttes and also produces from the Forbes sandstone. Our working interests range from 6.3% to 96.0%. Net daily production during the first half of 2001 averaged 1,365 Mcfe and we had proved reserves of 4,155 MMcfe at December 31, 2000. There has been limited development in the field during recent years, and during 2001 we plan to conduct a 22 square mile 3-D survey over our acreage in the Grimes field. We believe that the 3-D survey will result in multiple development and exploitation drilling opportunities similar to those that we have completed in the Sutter Buttes area since late 1998. Greeley Field. The Greeley field is located in Kern County, California and is our only oil producing property in California. We own an 85.4% working interest in this field. Unlike most California properties, the Greeley field produces light, sweet crude oil from the Olcese Sand at a depth of approximately 10,500 feet. Net daily production during the first half of 2001 averaged 280 Mcfe and we had proved reserves of 3,344 MMcfe at December 31, 2000. During 2001 we plan to drill one development well targeting 1.5 Bcfe of proved undeveloped reserves. 56 OIL AND NATURAL GAS RESERVES The following table sets forth information with respect to our estimated net proved oil and natural gas reserves and the related present values of such reserves at the dates shown. The reserve and present value data for our existing properties as of December 31, 1998, 1999 and 2000 have been prepared by Huddleston & Co., Inc. <Table> <Caption> AT DECEMBER 31, ------------------------------ 1998 1999 2000 -------- -------- -------- Proved Reserves: Oil and condensate (MBbls)....................... 11,319 15,851 15,073 Natural gas (MMcf)............................... 111,149 110,092 89,699 Total (MMcfe)............................ 179,063 205,198 180,137 Proved Developed Reserves: Oil and condensate (MBbls)....................... 9,124 12,957 12,290 Natural gas (MMcf)............................... 58,088 58,265 45,575 Total (MMcfe)............................ 112,832 136,007 119,315 PV-10 Value (in thousands)(1)...................... $118,151 $292,495 $630,002 Standardized Measure (in thousands)(2)............. $105,403 $231,564 $472,279 Reserve life (in years)............................ 13.9 14.8 11.0 </Table> --------------- (1) The average prices used in calculating PV-10 Value as of December 31, 2000 were $10.31 per Mcf and $25.90 per Bbl. Assuming benchmark prices of $4.25 per Mcf and $25.00 per Bbl (or net realized prices of $4.82 per Mcf and $24.10 per Bbl), our PV-10 Value would have been $309.3 million at December 31, 2000. (2) Represents PV-10 Value adjusted for the effects of future estimated income tax expense. Effective February 1, 2001, we gained an incremental 4.1 Bcfe of proved reserves, estimated at December 31, 2000, in our Hastings Complex due to the resolution of certain litigation which resulted in an assignment of additional interests. Estimated quantities of proved reserves and future net revenues therefrom are affected by oil and natural gas prices, which have fluctuated widely in recent years. There are numerous uncertainties inherent in estimating oil and natural gas reserves and their values, including many factors beyond the control of the producer. Reservoir engineering is a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. As a result, estimates of different engineers, including those used by us, may vary. In addition, estimates of reserves are subject to revision based upon actual production, results of future development and exploration activities, prevailing oil and natural gas prices, operating costs and factors, which revisions may be material. Accordingly, reserve estimates are often different from the quantities of oil and natural gas that are ultimately recovered and are highly dependent upon the accuracy of the assumptions upon which they are based. In general, the volume of production from oil and natural gas properties declines as reserves are depleted. Except to the extent we acquire properties containing proved reserves or conduct successful exploration and development activities, or both, our proved reserves will decline as reserves are produced. Our future oil and natural gas production is, therefore, highly dependent upon our level of success in finding or acquiring additional reserves. Exploring for, developing or acquiring new reserves requires substantial amounts of capital. We file reports of our estimated oil and natural gas reserves with the Department of Energy. The reserves reported to this agency are required to be reported on a gross operated basis and therefore are not comparable to the reserve data reported herein. 57 NET PRODUCTION, UNIT PRICES AND COSTS The following table sets forth certain information with respect to oil and natural gas production, prices and costs attributable to all of our oil and natural gas property interests for the periods shown: <Table> <Caption> SIX MONTHS ENDED YEARS ENDED DECEMBER 31, JUNE 30, --------------------------- ----------------- 1998 1999 2000 2000 2001 ------- ------- ------- ------- ------- Production Volumes: Oil and condensate (MBbls)................ 1,030 1,145 1,333 540 692 Natural gas (MMcf)........................ 6,711 7,007 8,314 3,413 4,615 Total (MMcfe)..................... 12,890 13,874 16,313 6,653 8,767 Average Daily Production: Oil and condensate (Bbls)................. 2,821 3,136 3,643 2,983 3,823 Natural gas (Mcf)......................... 18,387 19,196 22,716 18,856 25,497 Total (Mcfe)...................... 35,314 38,011 44,574 36,757 48,436 Average Realized Prices:(1) Oil and condensate (per Bbl).............. $ 12.43 $ 17.27 $ 28.95 $ 29.27 $ 27.62 Natural gas (per Mcf)..................... 1.94 2.36 4.19 2.93 7.78 Per Mcfe.......................... 2.00 2.61 4.50 3.94 6.24 Expenses (per Mcfe): Lease operating (excluding workover expenses and production taxes)......... $ 1.35 $ 1.12 $ 1.19 $ 1.02 $ 1.20 Workover.................................. 0.05 0.17 0.41 0.26 0.38 Production taxes.......................... 0.05 0.05 0.12 0.11 0.15 Depletion, depreciation and amortization........................... 0.96 0.80 0.83 0.81 0.83 General and administrative, net........... 0.26 0.38 0.27 0.37 0.36 </Table> --------------- (1) Reflects the actual realized prices received, including the results of hedging activities.

The price we receive for our oil and natural gas production depends on numerous factors beyond our control. Historically the markets for oil and natural gas have been volatile and are likely to continue to be volatile in the future. Prices for oil and natural gas are subject to wide fluctuation in response to relatively minor changes in the supply and demand for oil and natural gas, market uncertainty and a variety of additional factors. These factors include the level of consumer product demand, weather conditions, domestic and foreign governmental regulations, the price and availability of alternative fuels, political conditions in the Middle East, the actions of OPEC, the foreign supply of oil and natural gas and overall economic conditions. It is impossible to predict future oil and natural gas price movements with any certainty. We, from time to time, use swap and option contracts to mitigate the volatility of price changes on commodities we produce and sell, as well as to lock in prices to protect the economics related to certain capital projects. Approximately 80% of our projected oil and natural gas production from proved developed producing reserves (and the basis differential attributable to approximately 80% of our projected proved developed producing natural gas production from our California properties) is hedged through June 30, 2003 at swap prices of $4.19 per Mcf and $25.30 per Bbl, or a weighted-average natural gas-equivalent price of approximately $4.20 per Mcfe. In connection with the issuance of the old notes, we agreed to maintain, on a monthly basis, a rolling two-year hedge program until the maturity of the old notes and the new notes, subject to certain conditions. COMPETITION AND MARKETS Competition is intense in all areas of the our operations. Major and independent oil and natural gas companies and oil and natural gas syndicates actively bid for desirable oil and natural gas properties, as well as for the equipment and labor required to operate and develop such properties. Many of our competitors have financial resources and acquisition, exploration and development budgets that are substantially greater than ours, which may adversely affect our ability to compete with these companies. Many of our competitors have been engaged in the energy business for a 59 much longer time than us. Such companies may be able to pay more for productive oil and natural gas properties and exploratory prospects and to define, evaluate, bid for and purchase a greater number of properties and prospects than our financial or human resources permit. Our ability to acquire additional properties and to discover reserves in the future will depend on our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment. The market for oil and natural gas produced by us depends on factors beyond our control, including domestic and foreign political conditions, the overall level of supply of and demand for oil and natural gas, the price of imports of oil and natural gas, weather conditions, the price and availability of alternative fuels, the proximity and capacity of natural gas pipelines and other transportation facilities and overall economic conditions. The oil and natural gas industry as a whole also competes with other industries in supplying the energy and fuel requirements of industrial, commercial and individual consumers. REGULATION General. Various aspects of our oil and natural gas operations are subject to extensive and continually changing regulation, as legislation affecting the oil and natural gas industry is under constant review for amendment or expansion. Numerous departments and agencies, both federal and state, are authorized by statute to issue, and have issued, rules and regulations binding upon the oil and natural gas industry and its individual members. The Federal Energy Regulatory Commission ("FERC") regulates the transportation and sale of natural gas in interstate commerce pursuant to the Natural Gas Act of 1938 ("NGA") and the Natural Gas Policy Act of 1978 ("NGPA"). In the past, the federal government has regulated the prices at which oil and natural gas could be sold. While sales by producers of natural gas and all sales of crude oil, condensate and natural gas liquids can currently be made at uncontrolled market prices, Congress could reenact price controls in the future. Deregulation of wellhead sales in the natural gas industry began with the enactment of the NGPA in 1978. In 1989, Congress enacted the Natural Gas Wellhead Decontrol Act (the "Decontrol Act"). The Decontrol Act removed all remaining NGA and NGPA price and nonprice controls affecting wellhead sales of natural gas effective January 1, 1993. Regulation of Sales and Transportation of Natural Gas. Our sales of natural gas are affected by the availability, terms and cost of transportation. The price and terms for access to pipeline transportation are subject to extensive regulation. In recent years, the FERC has undertaken various initiatives to increase competition within the natural gas industry. As a result of initiatives like FERC Order No. 636, issued in April 1992, the interstate natural gas transportation and marketing system has been substantially restructured to remove various barriers and practices that historically limited non-pipeline natural gas sellers, including producers, from effectively competing with interstate pipelines for sales to local distribution companies and large industrial and commercial customers. The most significant provisions of Order No. 636 require that interstate pipelines provide firm and interruptible transportation service on an open access basis that is equal for all natural gas supplies. In many instances, the results of Order No. 636 and related initiatives have been to substantially reduce or eliminate the interstate pipelines' traditional role as wholesalers of natural gas in favor of providing only storage and transportation services. While the United States Court of Appeals upheld most of Order No. 636 last year, certain related FERC orders, including the individual pipeline restructuring proceedings, are still subject to judicial review and may be reversed or remanded in whole or in part. While the outcome of these proceedings cannot be predicted with certainty, we do not believe that we will be affected materially differently than our competitors. The FERC has also announced several important transportation-related policy statements and proposed rule changes, including a statement of policy and a request for comments concerning alternatives to its traditional cost-of-service rate making methodology to establish the rates interstate pipelines may charge for their services. A number of pipelines have obtained FERC authorization to charge negotiated rates as one such alternative. In February 1997, the FERC announced a broad 60 inquiry into issues facing the natural gas industry to assist the FERC in establishing regulatory goals and priorities in the post-Order No. 636 environment. Similarly, the Texas Railroad Commission has been reviewing changes to its regulations governing transportation and gathering services provided by intrastate pipelines and gatherers. While the changes being considered by these federal and state regulators would affect us only indirectly, they are intended to further enhance competition in natural gas markets. We cannot predict what further action the FERC or state regulators will take on these matters, however, we do not believe that any action taken will affect us materially differently than other natural gas producers with which we compete. Additional proposals and proceedings that might affect the natural gas industry are pending before Congress, the FERC, state commissions and the courts. The natural gas industry historically has been very heavily regulated; therefore, there is no assurance that the less stringent regulatory approach recently pursued by the FERC and Congress will continue. Oil Price Controls and Transportation Rates. Our sales of crude oil, condensate and natural gas liquids are not currently regulated and are made at market prices. The price we receive from the sale of these products may be affected by the cost of transporting the products to market. Environmental Matters. Extensive federal, state and local laws regulating the discharge of materials into the environment or otherwise relating to the protection of the environment affect our oil and natural gas operations. Numerous governmental departments issue rules and regulations to implement and enforce such laws, which are often difficult and costly to comply with and which carry substantial administrative, civil and even criminal penalties for failure to comply. These laws, rules and regulations may require the acquisition of certain permits, restrict or prohibit the types, quantities and concentration of substances that can be released into the environment in connection with drilling and production, restrict or prohibit drilling activities that could impact wetlands, endangered or threatened species or other protected natural resources and impose substantial liabilities for pollution resulting from our operations. Some laws, rules and regulations relating to protection of the environment may, in certain circumstances, impose strict liability for environmental contamination, rendering a person liable for environmental damages and cleanup costs without regard to negligence or fault on the part of such person. Other laws, rules and regulations may restrict the rate of oil and natural gas production below the rate that would otherwise exist. In addition, state laws often require various forms of remedial action to prevent pollution, such as closure of inactive pits and plugging of abandoned wells. The regulatory burden on the oil and natural gas industry increases our cost of doing business and consequently affects our profitability. We believe that we are in substantial compliance with current applicable environmental laws, rules and regulations, that we have no material commitments for capital expenditures to comply with existing environmental requirements and that continued compliance with existing requirements will not have a material adverse impact on our operations. However, environmental laws, rules and regulations have been subject to frequent changes over the years, and the imposition of more stringent requirements could have a material adverse effect upon our capital expenditures, earnings or competitive position as well as those of the oil and gas industry in general. The Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), also known as the "Superfund Law," and analogous state laws impose liability without regard to fault or the legality of the original conduct on certain classes of persons that are considered to have contributed to the release of a "hazardous substance" into the environment. These persons include the current or former owner or operator of the site or sites where the release occurred and companies that disposed or arranged for the disposal of the hazardous substances found at the site. Under CERCLA, such persons may be subject to joint and several liability for the costs of investigating and cleaning up hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. In addition, companies that incur liability frequently also confront third party claims because it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances or other pollutants released into the environment. 61 The Federal Solid Waste Disposal Act, as amended by the Resource Conservation and Recovery Act of 1976 ("RCRA"), regulates the generation, transportation, storage, treatment and disposal of hazardous wastes and can require cleanup of hazardous waste disposal sites. RCRA currently excludes drilling fluids, produced waters and other wastes associated with the exploration, development or production of oil and natural gas from regulation as "hazardous waste." Disposal of such non-hazardous oil and natural gas exploration, development and production wastes usually are regulated by state law. Other wastes handled at exploration and production sites or generated in the course of providing well services may not fall within this exclusion. Moreover, stricter standards for waste handling and disposal may be imposed on the oil and natural gas industry in the future. From time to time legislation is proposed in Congress that would revoke or alter the current exclusion of exploration, development and production wastes from the RCRA definition of "hazardous wastes" thereby potentially subjecting such wastes to more stringent handling, disposal and cleanup requirements. State initiatives to further regulate the disposal of oil and natural gas wastes and naturally occurring radioactive materials could have a similar impact on us. If such legislation were enacted it could have a significant impact on our operating costs, as well as those of the oil and natural gas industry in general. The impact of future revisions to environmental laws and regulations cannot be predicted. We own or lease, and have in the past owned or leased, properties that have been used for the exploration and production of oil and natural gas. Although we have utilized operating and disposal practices that were standard in the industry at the time, hydrocarbons or other wastes may have been disposed of or released on or under these properties or on or under other locations where such wastes have been taken for storage or disposal. In addition, many of these properties have been operated by third parties whose treatment and release of hydrocarbons or other wastes was not under our control. These properties and the wastes disposed thereon may be subject to CERCLA, RCRA and analogous state laws. Under such laws, we could be required to remove or remediate previously released wastes or property contamination. The Oil Pollution Act of 1990 ("OPA") and rules and regulations promulgated pursuant thereto impose a variety of obligations on "responsible parties" with respect to the prevention of oil spills and liability for damages resulting from such spills. A "responsible party" includes the owner or operator of an onshore facility, vessel, or pipeline or the lessee or permittee of the area in which an offshore facility is located. Under OPA, a person owning or operating a facility from which there is a discharge or threat of a discharge of oil into navigable waters or adjoining shorelines is subject to strict joint and several liability for all containment and cleanup costs and certain other damages, including natural resource damages. OPA establishes a liability limit for onshore facilities of $350 million and for offshore facilities, all removal costs plus $75 million; however, a party cannot take advantage of this liability limit if the spill is caused by gross negligence or willful misconduct, resulted from a violation of a federal safety, construction, or operating regulation, or if a party fails to report a spill or cooperate in the cleanup. Few defenses exist to the liability imposed by OPA. OPA also imposes ongoing requirements on a responsible party, including preparation of an oil spill contingency plan and proof of financial responsibility to cover a substantial portion of environmental cleanup and restoration costs that could be incurred by governmental entities in connection with an oil spill. Under OPA and rules adopted by the Minerals Management Service ("MMS"), responsible parties of covered offshore facilities that have a worst case oil spill of more than 1,000 barrels must demonstrate financial responsibility in amounts ranging from at least $10 million in state waters to at least $35 million in Outer Continental Shelf ("OCS") waters, with higher amounts of up to $150 million in certain limited circumstances where the MMS believes such a level is justified by the risks posed by the operations or if the worst case oil spill discharge volume possible at the facility may exceed applicable threshold volumes specified in the MMS's rules. We believe that we are in substantial compliance with OPA, including having appropriate spill contingency plans and certificates of financial responsibility in place. 62 We have resolved claims by the MMS relating to civil penalties for incidences of noncompliance with certain regulatory requirements on certain of our offshore platforms, as discussed under the heading "Legal Proceedings -- Minerals Management Service." The Federal Water Pollution Control Act ("FWPCA") and analogous state laws impose strict controls regarding the discharge of pollutants, including produced waters and other oil and natural gas wastes, into state waters or waters of the United States. The discharge of pollutants into regulated waters is prohibited, except in accord with the terms of a permit issued by EPA or the state. Sanctions for unauthorized discharges include administrative, civil and criminal penalties, as well as injunctive relief. We believe we are in substantial compliance with applicable FWPCA requirements and that any non-compliance would not have a material adverse effect on us. Our operations are also subject to the Clean Air Act ("CAA") and comparable state and local requirements. Amendments to the CAA were adopted in 1990 and contain provisions that may result in the gradual imposition of certain pollution control requirements with respect to air emissions from our operations. We may be required to incur certain capital expenditures in the next several years for air pollution control equipment in connection with obtaining and maintaining operating permits and approvals for air emissions. However, we believe our operations will not be materially adversely affected by any such requirements, and the requirements are not expected to be any more burdensome to us than to other similarly situated companies involved in oil and natural gas exploration and production activities. We maintain insurance against "sudden and accidental" occurrences, which may cover some, but not all, of the risks described above. The insurance we maintain may not cover the risks described above. There can be no assurance that such insurance will continue to be available to cover all such costs or that such insurance will be available at premium levels that justify its purchase. The occurrence of a significant event not fully insured or indemnified against could have a material adverse effect on our financial condition and operations. Regulation of Oil and Natural Gas Exploration and Production. Our exploration and production operations are subject to various types of regulation at the federal, state and local levels. Such regulations include requiring permits and drilling bonds for the drilling of wells, regulating the location of wells, the method of drilling and casing wells, and the surface use and restoration of properties upon which wells are drilled. Many states also have statutes or regulations addressing conservation matters, including provisions for the utilization or pooling of oil and natural gas properties, the establishment of maximum rates of production from oil and natural gas wells and the regulation of spacing, plugging and abandonment of such wells. Some state statutes limit the rate at which oil and natural gas can be produced from our properties. EMPLOYEES As of June 30, 2001, we had approximately 54 full time salaried employees and approximately 16 contract employees. None of our employees are subject to a collective bargaining agreement. In addition to our employees, we may utilize the services of independent geological, engineering, land and other consultants from time to time. TITLE TO PROPERTIES We have obtained title reports on substantially all of our producing properties and believe that we have satisfactory title to such properties in accordance with standards generally accepted in the oil and natural gas industry. As is customary in the oil and natural gas industry, we perform a minimal title investigation before acquiring undeveloped properties. We also obtain title opinions prior to the commencement of drilling operations on such properties. Our properties are subject to customary royalty interests, liens incident to operating agreements, liens for current taxes and other burdens which we believe do not materially interfere with the use of or materially affect the value of such properties. 63 LEGAL PROCEEDINGS From time to time, we are party to litigation or other legal proceedings that we consider to be a part of the ordinary course of our business. Other than as set forth below, we are not involved in any legal proceedings nor are we party to any pending or threatened claims that could reasonably be expected to have a materially adverse effect on our financial condition, cash flow or results of operations. Bankruptcy filing On March 14, 2000, we filed a voluntary petition under Chapter 11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Texas, Houston Division. We filed our amended plan of reorganization in the bankruptcy proceeding on May 9, 2001. Our plan provided for payment in cash, or segregation of funds for the payment, to each creditor of its full, allowed claim, including interest, on the closing date of the original offering. Our plan was confirmed by a court order on May 23, 2001, subject to the completion of the offering of the old notes. Upon the closing of the offering, we paid or segregated funds for the payment of all allowed claims in accordance with our plan and the court order and, except as specifically discussed below, lawsuits, administrative actions and other proceedings that arose prior to the confirmation were dismissed as to us. Claims that we dispute will be heard by the bankruptcy court. If claims are resolved for less than the amount segregated by us, we will receive the balance of the funds. Credit Lyonnais and Credit Lyonnais Securities In March 2000, we and Richard Bowman filed suit against Credit Lyonnais, New York Branch and Credit Lyonnais Securities (USA), Inc. in the 16th Judicial District Court of Harris County, Texas asserting claims for violations of the Federal Bank Tying Act, fraud and tortious interference. Credit Lyonnais filed a counterclaim against us seeking repayment of monies loaned by Credit Lyonnais to us, interest and attorney's fees. At the time these claims arose, Credit Lyonnais was our senior secured lender. Specifically, we alleged that we were wrongfully induced into incurring additional secured indebtedness associated with the acquisition of certain oil and natural gas properties from Apache Corporation. This additional indebtedness was to be refinanced on a short term basis by a debt or equity offering underwritten or privately placed by Credit Lyonnais and/or its securities affiliate, Credit Lyonnais Securities, Inc. We alleged that Credit Lyonnais advised us that it would not increase our credit facility to an amount necessary to consummate the acquisition from Apache unless we entered into an agreement with Credit Lyonnais Securities to act as our exclusive financial advisor for such an offering. We agreed to enter into such an arrangement based upon representations made to us regarding the ability, experience and expertise of Credit Lyonnais Securities to assist us in such an offering. We further alleged that no meaningful effort was made on the part of Credit Lyonnais or Credit Lyonnais Securities to assist us in raising the funds necessary to refinance our credit facility. As part of the confirmation of our plan we and Richard Bowman reached a settlement of this litigation in May 2001. The terms of the settlement included a reduction in the amount of the secured claim of Credit Lyonnais in the approximate amount of $3.3 million and our agreement not to dispute, other than for arithmetic error, the remainder of Credit Lyonnais' secured claim, in the approximate amount of $127.3 million, including principal, interest, fees and expenses as of May 31, 2001. Richard Bowman assigned his interest in the settlement to us. Chieftain International On March 31, 1999, Chieftain International (U.S.) Inc. filed suit against us in the United States District Court for the Eastern District of Louisiana (the "bankruptcy court") alleging that we owe joint interest expenses in the amount of approximately $3.0 million, together with accrued interest, attorneys' fees and costs, in connection with Chieftain's operation of two mineral leases. No action on this suit was taken during our bankruptcy. The plaintiff has filed a motion with the United States 64 Bankruptcy Court for the Southern District of Texas, Houston Division, requesting that the state district court in Louisiana be allowed to liquidate the claim. The motion is currently pending. We intend to continue to vigorously defend this suit. Funds in the amount of approximately $5.5 million were segregated in accordance with our plan, pending the trial or resolution of this dispute in Louisiana. Seitel Data, Ltd. and DDD Energy, Inc. On December 13, 2000, Seitel Data, Ltd., and DDD Energy, Inc., filed suit against Tribo Petroleum Corporation in the 334th Judicial District of Harris County, Texas, alleging that Tribo owed approximately $0.8 million in damages, together with interest and attorney's fees for goods and services delivered for our benefit. We paid the full amount of this claim, together with interest, in accordance with our plan. Minerals Management Service We have reached a settlement with the MMS that resolves a civil enforcement action first brought against us in August 2000, with respect to certain alleged violations of MMS rules relating to the operation of our offshore facilities prior to the commencement of our bankruptcy proceedings. As part of the settlement, we have agreed to pay civil penalties in the amount of $506,500, with $25,325 paid out initially, and the remaining $481,175 paid out in quarterly installments over a two-year period. We have also agreed to provide the MMS with approximately $9.8 million in operators bonds. The settlement between the MMS and us is not an admission of liability with respect to the violations alleged by the MMS. Arch W. Helton, Helton Properties, Inc., and Linda Barnhill On May 28, 1997, Arch W. Helton and Helton Properties, Inc., filed suit against us in the 80th Judicial District Court of Harris County, Texas ("state court"). Subsequently, Linda Barnhill joined as a plaintiff. The suit alleges that we owe additional royalties on oil and natural gas produced from February 1987 to date as to certain completions in oil and natural gas properties located in Alvin, Texas, that oil and natural gas was drained from approximately 18 acres in which they claim interests and seeks the recovery of attorneys' fees. This suit has been dismissed from state court. The plaintiff's proof of claim in our bankruptcy is all that remains. This claim is currently pending in the United States Bankruptcy Court for the Southern District of Texas, Houston Division. We intend to continue to vigorously defend this suit. Funds in the amount of approximately $1.0 million have been segregated in accordance with our plan pending the resolution of this dispute by the bankruptcy court. We believe these funds are sufficient to cover our net interest in the full proof of claim filed in the amount of $3.0 million. OPERATING HAZARDS AND RISKS The oil and natural gas business involves a variety of operating risks, including the risk of fire, explosions, blow outs, pipe failure, abnormally pressured formations and environmental hazards such as oil spills, natural gas leaks, ruptures or discharges of toxic gases. Any of these occurrences could result in substantial losses to us due to injury or loss of life, severe damage to or destruction of property, natural resources and equipment, environmental damage, clean-up responsibilities, regulatory investigation and penalties and suspension of operations. Drilling activities are subject to many risks, including the risk that no commercially productive reservoirs will be encountered. We cannot assure you that new wells drilled by us will be productive or that we will recover all or any portion of our investment. Drilling for oil and natural gas may involve unprofitable efforts, not only from dry wells, but from wells that are productive but do not produce sufficient net revenues to return a profit after drilling, operating or other costs. The cost of drilling, completing and operating wells is often uncertain. Our drilling operations may be curtailed, delayed or canceled as a result of numerous factors, many of which are beyond our control, including title problems, weather conditions, mechanical problems, compliance with governmental requirements 65 and shortages and delays in the delivery of equipment and services. Our future drilling activities may not be successful and, if unsuccessful, such failure may have a material adverse effect on our future results of operations and financial condition. Although we currently maintain insurance coverage considered to be customary in each industry in which we participate, we are not fully insured against certain risks, either because insurance is not available or because of the high premium costs. We do maintain certain forms of physical damage, employer's liability, comprehensive commercial general liability and workers' compensation insurance. We cannot assure you that any insurance obtained by us will be adequate to cover any losses or liabilities, or that such insurance will continue to be available or available on terms which are acceptable to us. 66 MANAGEMENT Our directors and principal executive officers are: <Table> <Caption> NAME AGE POSITION ---- --- -------- Richard Bowman........................ 36 Founder, President, Chief Executive Officer and Director Jeffrey T.

EMPLOYMENT AGREEMENTS WITH EXECUTIVE OFFICERS We are negotiating but have not yet finalized an employment agreement with Richard Bowman to serve as our Chairman of the Board, President and Chief Executive Officer. We anticipate that this agreement will provide for a term commencing on June 18, 2001 and continuing through April 30, 2006, unless renewed for additional periods. We anticipate that Mr. Bowman will receive a base salary of $350,000 annually during the initial calendar year, increasing annually by the greater of 5% or an amount approved by our Board of Directors. Mr. Bowman will also be entitled to other benefits including, but not limited to, paid vacation, an automobile allowance, reimbursement of out-of-pocket business expenses and a performance bonus which is expected to be equal to the greater of (i) an amount approved by our Board of Directors or (ii) (A) zero, if our EBITDA is less than $40 million and (B) if our EBITDA is $40 million or more, then the sum of (1) .5% of our EBITDA between zero and $59,999,999 and (2) 1% of our EBITDA greater than $60,000,000. The employment agreement is also expected to contain a severance package and a payment upon a change of control, the terms of which are currently being negotiated. We do not currently have employment agreements with our other executive officers. We intend to enter into employment agreements with each of them on terms that are reflective of current market conditions and are in the process of negotiating these terms. PRINCIPAL STOCKHOLDERS An aggregate of 433,333 shares of our common stock were issued and outstanding on June 30, 2001, consisting of 368,333 shares of class A common stock and 65,000 shares of class B common stock. Of these shares, Richard Bowman, our President and Chief Executive Officer, owns 238,333 shares of class A common stock (or 55% of our common stock), the purchasers of units in the original offering own an aggregate of 130,000 shares of class A common stock (or 30% of our common stock) and Jefferies owns 65,000 shares of class B common stock (or 15% of our common stock). CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS As a private company, we historically have had a series of informal relationships with Richard Bowman and his affiliated companies, including advances to Richard Bowman, our sole shareholder, for travel and other business expenses. Under the terms of the indenture, on a prospective basis, all transactions with affiliates must be on terms as favorable to us as could be obtained from unaffiliated third parties. OFFICE LEASE WITH TRIBO PRODUCTION CO. LTD. Effective April 1, 2001, we relocated our executive offices to 530 Lovett Boulevard, Houston, Texas, in a building owned by our affiliate, Tribo Production Co. Ltd., which is beneficially owned by Richard Bowman, our President, Chief Executive Officer and director. We occupy the entire building, which has approximately 9,355 square feet of office space. We currently occupy this space at a 69 base rental of $26,000 per month, which was determined based upon independent market data. The base rental is subject to adjustment for changes in the consumer price index during the term of the lease. Pursuant to the lease, we are responsible for certain expenses associated with the building, including property taxes, insurance, maintenance and utilities. The lease expires on March 31, 2006. The lease contains five one-year renewal options at the then prevailing market rental rate which may be exercised upon six months notice to our landlord. We believe the terms of this lease are as favorable to us as could be obtained from unaffiliated third parties. CERTAIN TRANSACTIONS WITH ATASCA RESOURCES, INC. We have historically provided and intend to continue to provide limited general and administrative services, such as accounting, landman and engineering services to Atasca Resources, Inc., an entity owned and controlled by Richard Bowman ("Atasca"). Annually, we commission an independent peer group analysis of companies similar to Atasca in order to determine market levels for such services. Based upon this analysis and the actual services performed, we allocated certain general and administrative expenses to Atasca. For the year ended December 31, 2000, we received reimbursements totaling $60,000 from Atasca for these services. Through June 30, 2001, we allocated $5,000 per month to Atasca for the rendering of such services. We believe the terms of these arrangements are as favorable to us as could be obtained from unaffiliated third parties. In addition, during 2000 and continuing until Tribo's properties were assigned to Atasca and we merged with Tribo, a small number of Tribo's oil and natural gas properties were operated by Atasca. Tribo paid Atasca for ordinary and customary lease operating expense incurred in connection with the operation of these properties. During the year ended December 31, 2000, we received oil and natural gas revenues of $585,692 and incurred production and overhead expenses of $237,807. For the period from January 1, 2001 through June 18, 2001, we received oil and natural gas revenues of $146,902 and incurred production and overhead expenses of $88,745. CASH ADVANCES WITH AFFILIATED ENTITIES Historically, we have made cash advances to, and have received cash advances from, Atasca, Tribo Production Co., Ltd., BL Production Co., Ltd., and Atasca Properties, Ltd., entities that are beneficially owned or controlled by Richard Bowman. The advances were made primarily for insurance, oilfield services and related activities and reimbursement of corporate expenses. Cash advanced from these affiliates was $488,308 for the year ended December 31, 2000, and $161,265 for the period from January 1, 2001 through June 18, 2001, reducing the net balance owed to us from these entities to $364,667 at December 31, 2000 and $203,402 at June 18, 2001. On June 18, 2001, all net amounts due from Mr. Bowman and entities owned by him were forgiven as partial consideration for the assignment by Mr. Bowman of his interest in a $3.3 million litigation settlement with Credit Lyonnais as more fully described in the "Satisfaction of Certain Related Party Obligations" section. OTHER TRANSACTIONS WITH RICHARD BOWMAN The total amount owed to us by Mr. Bowman for travel and other business expenses was $142,165, $354,953 and $625,199 at December 31, 1998, 1999 and 2000, respectively and $581,975 at June 18, 2001. These advances were non-interest bearing and due on demand. On June 18, 2001, all net amounts due from Mr. Bowman and entities owned by him were forgiven as partial consideration for the assignment by Mr. Bowman of his interest in a $3.3 million litigation settlement with Credit Lyonnais as more fully described in the "Satisfaction of Certain Related Party Obligations" section. 70 SATISFACTION OF CERTAIN RELATED PARTY OBLIGATIONS As noted in "Business and Properties -- Legal Proceedings," Richard Bowman agreed to assign his interest in a $3.3 million litigation settlement with Credit Lyonnais to us. Mr. Bowman's interest in this settlement has not yet been determined, however, he agreed to assign this interest to us in return for our transfer to Atasca of certain oil and natural gas properties (totaling approximately 1.2 Bcfe, or 0.7% of our proved reserves, as of December 31, 2000) at their book value of approximately $1.1 million owned by Tribo Petroleum Corporation and the net obligations owed to us by Richard Bowman. Additionally, we released Tribo Production Company, Ltd., BL Production Co., Ltd., and Atasca Properties, Ltd., (all wholly owned by Richard Bowman) from the net obligations they each owed to us. In July 2001, we merged with Tribo Petroleum Corporation. After giving effect to these transactions, all balances owing to and from us and these related parties were satisfied. As a consequence of these transactions, we recorded a one time non-cash reorganization expense of $1,882,990. The following table summarizes the oil and gas properties transferred to Atasca, the net balances owing to us by Richard Bowman, Atasca Resources, Inc., and all other companies controlled by Richard Bowman that we forgave in this transaction. <Table> <Caption> ASSETS TRANSFERRED AND RECEIVABLES FORGIVEN BY TDC -------------------------------------------------- Oil and gas properties transferred to Atasca Resources, Inc....................................................... $1,097,611 Richard Bowman.............................................. 581,975 Due from Tribo Production Co................................ 491,878 Due from Atasca Resources, Inc.............................. 109,796 Due from BL Production, LLC................................. 55,844 ---------- TOTAL............................................. $2,337,105 ========== </Table> <Table> <Caption> LIABILITIES OF TDC CANCELLED ---------------------------- Due to Tribo Production Co.................................. $ 2,388 Due to Atasca Resources, Inc................................ 396,742 Due to Atasca Properties, Inc............................... 16,885 Due to BL Production, LLC................................... 23,458 Due to Atasca Properties.................................... 14,643 ---------- TOTAL LIABILITIES CANCELLED....................... 454,116 ========== NET ASSETS TRANSFERRED AND RECEIVABLES FORGIVEN... $1,882,990 ========== </Table> DESCRIPTION OF THE SENIOR SECURED NOTES The terms and provisions of the old notes and the new notes are identical, except that the transfer restrictions and registration rights applicable to the old notes will generally not apply to the new notes, and the following description is applicable to both the old notes and the new notes. The old notes have been, and the new notes will be, issued under an indenture among Tri-Union, as issuer, and Firstar Bank, National Association, as trustee. You can find some of the definitions of certain terms used in this description under "-- Certain Definitions" below. Capitalized terms not otherwise defined in this "Description of the Senior Secured Notes" have the meanings given to them in the indenture. The following description is a summary of the material provisions of the indenture, the Guaranty Agreement and the Security Documents. This summary does not restate those documents in their entirety. We urge you to read the indenture, the Guaranty Agreement and the Security Documents because they, and not this description, define your rights as a Holder. A copy of the form of indenture, the Guaranty Agreement and the Security Documents may be obtained from us. 71 BRIEF DESCRIPTION OF THE NOTES AND THE GUARANTEES The Notes The Notes: - are senior secured obligations of Tri-Union; - are secured by a first priority Lien, subject only to Permitted Liens and certain payment priorities set forth in the Security Documents, on substantially all of the oil and gas assets of Tri-Union; - rank equally in contractual right of payment with all of Tri-Union's current and future senior Indebtedness; - rank senior to all of Tri-Union's current and future Subordinated Obligations; and - are unconditionally guaranteed by Tri-Union Operating Company and will be unconditionally guaranteed by any future Subsidiary Guarantors. The Guarantees The Notes are guaranteed by Tri-Union Operating Company and any future Subsidiary Guarantor. The guarantees of the Notes: - are and will be senior secured obligations of the Subsidiary Guarantors; - are and will be secured by a first priority Lien, subject only to Permitted Liens and certain payment priorities set forth in the Security Documents, on substantially all of the oil and gas assets of the Subsidiary Guarantors; - rank equally in contractual right of payment with all of the current and future senior Indebtedness of the Subsidiary Guarantors; and - rank senior to all of the Subsidiary Guarantor's current and future Subordinated Obligations. PRINCIPAL, MATURITY AND INTEREST Tri-Union may issue Notes from time to time with a maximum aggregate principal amount of $150,000,000, of which $130,000,000 were issued in the original offering that closed on June 18, 2001 (the "Old Notes"). Any Tack-On Senior Secured Notes will be subject to the debt incurrence covenant described in the first paragraph under the heading "-- Certain Covenants -- Limitation on Indebtedness." Any Tack-On Senior Secured Notes that are actually issued will be treated as issued and outstanding Notes (as the same class as the Old Notes) for all purposes of the indenture and this "Description of the Senior Secured Notes," unless the context indicates otherwise. The indenture also provides for the issuance of up to $150,000,000 of Notes (the "New Notes") that may be issued in exchange for either the Old Notes pursuant to the exchange offer described in this prospectus under "Registration Rights" or any Tack-On Senior Secured Notes pursuant to a similar exchange offer. Unless the content indicates otherwise, the Old Notes, the New Notes and any Tack-On Senior Secured Notes are collectively referred to as the "Notes" in this Description of Senior Secured Notes. Any Old Notes that remain outstanding after the completion of the exchange offer, together with the New Notes and any Tack-On Senior Secured Notes issued in the future, will be treated as a single class of securities under the indenture. Principal on the Notes is payable in installments beginning on June 1, 2002. The Notes will mature on June 1, 2006. The Notes bear interest at the rate of 12.5% per annum payable 72 semiannually on June 1 and December 1 of each year, respectively, commencing on December 1, 2001. Interest will accrue and be payable before and after the filing of a bankruptcy petition at the rate and on the dates set forth above. Interest on overdue principal and on overdue installments of interest, to the extent permitted by law, will accrue at 1% per annum in excess of the rate. Interest on the Notes will be computed on the basis of a 360-day year of twelve 30-day months. The Notes are issued only in fully registered form, without coupons, in denominations of $1,000 and any integral multiple of $1,000. No service charge shall be made for any registration of transfer or exchange of the Notes, but Tri-Union may require payment of a sum sufficient to cover any transfer tax or other similar governmental charge payable in connection therewith. AMORTIZATION PAYMENTS Principal on the Notes is payable in installments beginning on June 1, 2002 as set forth in the table below, together with accrued and unpaid interest to such date. All amortization payments prior to the stated maturity of the Notes will be made on a pro rata basis. <Table> <Caption> DATE AMOUNT ---- ------ June 1, 2002 The greater of: (a) $20,000,000 or (b) 15.3% of the aggregate principal amount of the Notes originally issued (including any Tack-On Senior Secured Notes) June 1, 2003 The greater of: (a) $20,000,000 or (b) 15.3% of the aggregate principal amount of the Notes originally issued (including any Tack-On Senior Secured Notes) reduced by any amortization payments made prior to the payment date June 1, 2004 The greater of: (a) $15,000,000 or (b) 11.5% of the aggregate principal amount of the Notes originally issued (including any Tack-On Senior Secured Notes) reduced by any amortization payments made prior to the payment date </Table> OPTIONAL REDEMPTION At any time prior to June 1, 2003, Tri-Union may redeem in the aggregate up to 30% of the then outstanding aggregate principal amount of the Notes with the Net Cash Proceeds of one or more Equity Offerings at a redemption price of 112.5% of the stated principal amount of the Notes, together with accrued and unpaid interest to the redemption date; provided that: (1) the redemption occurs within 60 days after the consummation of the Equity Offering; and (2) at least 70% of the then outstanding aggregate principal amount of the Notes remain outstanding after each redemption. Except pursuant to the preceding paragraph, the Notes will not be redeemable at Tri-Union's option prior to June 1, 2004. On or after June 1, 2004, Tri-Union may redeem all or part of the Notes upon not less than 30 nor more than 60 days' notice, from the date and at the redemption prices (expressed as percentages of the principal amount) set forth below plus accrued and unpaid interest, if any, on the Notes redeemed to the applicable redemption date: <Table> <Caption> DATE PERCENTAGE ---- ---------- On or after June 1, 2004.................................. 104% On or after June 1, 2005.................................. 100% </Table> 73 GUARANTEES Tri-Union's Obligations are guaranteed (all the obligations guaranteed being herein called the "Guaranteed Obligations" and each guarantee being herein called a "Guarantee") by the Subsidiary Guarantors, which initially will be Tri-Union Operating Company, pursuant to the Guaranty Agreement. Substantially all of the oil and gas assets of the Subsidiary Guarantor will be pledged to secure its obligations under the Guarantee. The Guarantees will rank equally in contractual right of payment with all of the current and future senior Indebtedness of the Subsidiary Guarantors, and senior to all of their respective current and future Subordinated Obligations. Each Subsidiary Guarantor will irrevocably and unconditionally guarantee, on a joint and several basis, the performance and the punctual payment when due, of all the Obligations of Tri-Union under the indenture and the Notes. Each Subsidiary Guarantee will be limited as necessary to prevent the Subsidiary Guarantee from constituting a fraudulent conveyance under applicable law. The Guarantee is a continuing guarantee and shall: (1) remain in full force and effect until payment in full in cash of all the Guaranteed Obligations; (2) be binding upon the relevant Subsidiary Guarantor; and (3) inure to the benefit of and be enforceable by the trustee, the Holders and their successors, transferees and assigns as provided in the indenture. Pursuant to the indenture, any Subsidiary Guarantor may consolidate with, merge with or into, or transfer all or substantially all its assets to any other Person if: (1) immediately after giving effect to the transaction, no Default or Event of Default exists; and (2) immediately after giving effect to the transaction on a pro forma basis, Tri-Union would be able to Incur an additional $1.00 of Indebtedness pursuant to paragraph (1) of the covenant described under the heading "-- Limitation on Indebtedness"; provided that if the Person is not Tri-Union or a Subsidiary Guarantor, the guarantor's obligations under the Guaranty Agreement must be expressly assumed by the other Person. Upon the sale or disposition, by merger or otherwise, of any Subsidiary Guarantor to a Person permitted by the indenture, the Subsidiary Guarantor will be released and relieved from all its obligations under the Guaranty Agreement. Please read "-- Certain Covenants -- Limitation on Sales of Assets" and "-- Merger and Consolidation." Any Subsidiary Guarantor that is designated an Unrestricted Subsidiary in accordance with the indenture will be likewise released and relieved from all such obligations. SECURITY; RANKING All of the Obligations and the Guaranteed Obligations are secured by (1) a first priority Lien in favor of the Collateral Agent for the benefit of the Approved Hedge Counterparties or the Hedge Liquidity Providers, the trustee and the Holders, subject only to Permitted Liens and certain payment priorities set forth in the Intercreditor Agreement, on substantially all of the oil and gas assets of Tri-Union and the Subsidiary Guarantors owned on the Closing Date; and (2) a first priority Lien, subject only to Permitted Liens, on substantially all of the oil and gas assets of Tri-Union and the Subsidiary Guarantors, including any future Subsidiary Guarantor, acquired or developed thereafter; 74 provided that, with respect to any property securing Acquired Indebtedness, Tri-Union's and each Subsidiary Guarantor's obligation to provide Liens on the property will be limited to the extent that granting the Lien is not prohibited by the terms of the instruments creating the Acquired Indebtedness, including any Refinancing; and the Lien, if not otherwise prohibited, may be junior to the Lien securing the Acquired Indebtedness. Please read "-- Certain Covenants -- Lien on Additional Collateral." If an Event of Default is continuing under the indenture, the trustee shall have the right to direct the Collateral Agent to take all actions necessary or appropriate, in accordance with the indenture, the Security Documents and applicable law, subject to the Intercreditor Agreement. However, only the Collateral Agent will be the secured party and entitled to enforce the Liens granted under the Security Documents. The Collateral Agent will also be obligated to take instructions from the Approved Hedge Counterparties or the Hedge Liquidity Providers following an early termination of any Approved Hedge Agreement pursuant to which Tri-Union owes a termination payment that has not been paid or following an event of default, however designated, under a Hedge Liquidity Agreement. The proceeds received from the sale of any Collateral that is the subject of a foreclosure or collection suit by the Collateral Agent will be applied in the following priority: (1) to pay and reimburse all fees, expenses and indemnities owed to the Collateral Agent; (2) to pay to: (a) the Approved Hedge Counterparties under Approved Hedge Agreements for which an early termination date has been designated of the net amount due to the Approved Hedge Counterparty and all accrued and unpaid interest and all fees, expenses, cash collateralization amounts, indemnities and other amounts owed to the Approved Hedge Counterparty; (b) the Approved Hedge Counterparties of regularly scheduled payments under Approved Hedge Agreements for which no early termination date has been designated; or (c) Hedge Liquidity Providers and their agents or representatives, if any, all cash collateralization amounts, principal, interest, fees, expenses and indemnities owed under their Hedge Liquidity Agreement; provided that if the moneys are insufficient to pay the entire amount then outstanding, then to make pro rata payments, without any preference or priority, to all Approved Hedge Counterparties or Hedge Liquidity Providers, as applicable; (3) to pay and reimburse all fees, expenses and indemnities owed to the trustee under the indenture; (4) to pay accrued and unpaid interest on the Notes, and if the moneys are insufficient to pay the entire amount then outstanding, then to make pro rata payments, without any preference or priority, to each Holder; (5) to pay the outstanding principal balance of the Notes, including any premium then due; and if the moneys are insufficient to pay the entire amount then outstanding, then to make pro rata payments, without any preference or priority, to each Holder; (6) to the Collateral Agent to hold as cash collateral to make payments or deposits due under the Approved Hedge Agreements, the Hedge Liquidity Agreement and the indenture until it determines that all such obligations have been paid in full or pay any other amounts which may be due and owing thereunder or under any Security Document; and (7) to the pay the remainder to Tri-Union or as a court of competent jurisdiction may otherwise direct. 75 The Collateral Agent has the power to institute and maintain such suits and proceedings as it may deem expedient to prevent impairment of, or to preserve or protect its, the Approved Hedge Counterparties' or Hedge Liquidity Providers', as applicable, and the Holders' interest in, the Collateral. Under the terms of the Intercreditor Agreement, following a Triggering Event, any Approved Hedge Counterparty or the Hedge Liquidity Provider, if applicable, until such time as all amounts due to it are paid, and thereafter the trustee may direct the circumstances and manner in which the Collateral will be disposed of; and, in any event, the Collateral Agent may take any action permitted under the Intercreditor Agreement or any Security Document or otherwise permitted or required by law. Under the terms of the Intercreditor Agreement, the Approved Hedge Counterparties or Hedge Liquidity Providers, as applicable, will be obligated to meet with the trustee to reach a consensus on the order and which properties to foreclose on, provided there is no obligation to reach any consensus and the failure to reach a consensus will not impair the right of such Person, or their representative, to proceed to enforce the Liens provided by the Security Documents. The Intercreditor Agreement will also provide that if, following a Triggering Event, any amounts are received by any of the Holders or any Approved Hedge Counterparty or Hedge Liquidity Providers, the trustee or the Collateral Agent, the amounts shall be distributed in a priority which will result in the Approved Hedge Counterparty or Hedge Liquidity Providers receiving payment in full for all amounts due to them under the Approved Hedge Agreements prior to any distribution being made to repay principal, interest or premium on the Notes. There can be no assurance that the Collateral Agent will be able to sell the Collateral without substantial delays or that the proceeds obtained will be sufficient to pay all amounts owing to the Approved Hedge Counterparties or Hedge Liquidity Providers, as applicable, and Holders and owners of Permitted Liens, if any. The Collateral release provisions of the indenture and the Security Documents will permit the release of Collateral without substitution of collateral of equal value under certain circumstances. Please read "-- Possession, Use and Release of Collateral." As senior obligations of Tri-Union and the relevant Subsidiary Guarantors, the Obligations and the Guaranteed Obligations will be senior to all of Tri-Union's and the relevant Subsidiary Guarantor's Subordinated Obligations and pari passu in contractual right of payment to all of Tri-Union's and the relevant Subsidiary Guarantor's other current and future senior Indebtedness. The Notes and the Guarantee will effectively, however, be senior as to other senior Indebtedness not granted a payment priority under the Security Documents on the basis of the Liens granted under the indenture and the Security Documents to the extent of the value of the Collateral. CERTAIN COVENANTS The indenture contains covenants including, among others, the following: Limitation on Indebtedness (1) Tri-Union shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided that Tri-Union or a Restricted Subsidiary may Incur Indebtedness if, on the date of the Incurrence and after giving effect thereto, both: (a) the Consolidated Coverage Ratio equals or exceeds 2.5 to 1.0; and (b) Adjusted Consolidated Net Tangible Assets equals or exceeds 150% of the aggregate consolidated Indebtedness of Tri-Union and the Restricted Subsidiaries. 76 (2) Notwithstanding the preceding paragraph (1), Tri-Union and any Restricted Subsidiary may Incur the following Indebtedness: (a) Indebtedness Incurred pursuant to any Working Capital Revolver, so long as the aggregate principal amount of all Indebtedness outstanding under all Working Capital Revolvers does not at any one time exceed $20,000,000; (b) Indebtedness owed to and held by Tri-Union or a Wholly Owned Subsidiary; provided that any subsequent issuance or transfer of any Capital Stock which results in any such Wholly Owned Subsidiary ceasing to be a Wholly Owned Subsidiary or any subsequent transfer of such Indebtedness, other than to Tri-Union or another Wholly Owned Subsidiary, shall be deemed, to constitute the Incurrence of such Indebtedness by the issuer thereof; (c) the Notes (other than the Tack-On Senior Secured Notes), the indenture, the Security Documents and the Subsidiary Guarantees; (d) Indebtedness outstanding on the Closing Date, to the extent not discharged in Tri-Union's bankruptcy case; (e) Refinancing Indebtedness in respect of Indebtedness Incurred pursuant to paragraph (1) or pursuant to clause (c) or (d) above or clause (f) below; (f) Indebtedness of Tri-Union or a Restricted Subsidiary represented by Capital Lease Obligations, mortgage financings or purchase money obligations Incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property used in the oil and gas business and Incurred no later than 365 days after the date of such acquisition or the date of completion of such construction or improvement; provided that the principal amount of all such Indebtedness at any one time outstanding shall not exceed $5,000,000; (g) Indebtedness consisting of Interest Rate Agreements directly related to Indebtedness permitted to be Incurred by Tri-Union and the Restricted Subsidiaries pursuant to this covenant; (h) Indebtedness under oil and gas hedging contracts entered into in the ordinary course of business for the purpose of limiting risks that arise in the ordinary course of business of Tri-Union and the Restricted Subsidiaries or required to be entered into by Tri-Union and the Restricted Subsidiaries as described under the heading "-- Hedging Obligations," and under certain revolving credit or loan agreements or letters of credit reimbursement agreements ("Hedge Liquidity Agreements") to permit Tri-Union or any of the Restricted Subsidiaries to provide letters of credit in lieu of the collateral to secure excess market exposure and settlement and related amounts due on early termination under the Approved Hedge Agreement and Security Documents; (i) Non-Recourse Indebtedness; (j) the guarantee by Tri-Union or any of the Restricted Subsidiaries of Indebtedness that was permitted to be incurred by another provision of this covenant; and (k) Indebtedness in an aggregate principal amount which, together with the principal amount of all other Indebtedness of Tri-Union and the Restricted Subsidiaries outstanding on the date of the Incurrence (other than Indebtedness permitted by clauses (a) through (j) above or paragraph (1)) does not exceed $5,000,000. (3) Notwithstanding the preceding, Tri-Union and the Restricted Subsidiaries shall not Incur any Indebtedness pursuant to the preceding paragraph (2) if the proceeds are used, directly or indirectly, to Refinance any Subordinated Obligations unless the Indebtedness shall be subordinated to the Notes to at least the same extent as the Subordinated Obligations. 77 (4) For purposes of determining compliance with the preceding covenant: (a) if an item of Indebtedness meets the criteria of more than one of the types of Indebtedness described above, Tri-Union, in its sole discretion, will classify the item of Indebtedness and only be required to include the amount and type of the Indebtedness in one of the above clauses; and (b) an item of Indebtedness may be divided and classified in more than one of the types of Indebtedness described above. Limitation on Restricted Payments (1) Tri-Union shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, make a Restricted Payment unless, at the time of the Restricted Payment: (a) no Default or Event of Default shall have occurred and be continuing or would occur as a consequence; (b) immediately after giving effect to the Restricted Payment on a pro forma basis, Tri-Union could incur at least $1.00 of additional Indebtedness under clause (1) of the covenant described under the heading "-- Limitation on Indebtedness"; and (c) the Restricted Payment, together with the aggregate amount of all other Restricted Payments made by Tri-Union and its Restricted Subsidiaries after the Closing Date, is less than the sum of: (i) 25% of the Consolidated Net Income of Tri-Union for the period (taken as one accounting period) from January 1, 2002 to the end of Tri-Union's most recently ended fiscal quarter for which internal financial statements are available at the time of the Restricted Payment (or, if the Consolidated Net Income for the period is a deficit, less 100% of the deficit), plus (ii) 100% of the aggregate net cash proceeds received by Tri-Union since the Closing Date from the issue or sale of Capital Stock of Tri-Union (other than Disqualified Stock) or of Disqualified Stock or debt securities of Tri-Union that have been converted into, or exchanged for, the Capital Stock (other than any Capital Stock, Disqualified Stock or convertible debt securities sold to a Restricted Subsidiary of Tri-Union and other than Disqualified Stock or convertible debt securities that have been converted into, or exchanged for, Disqualified Stock), plus (iii) to the extent that any Permitted Investment that was made after the Closing Date is sold for cash or otherwise liquidated or repaid for cash, the lesser of (A) the cash return of capital with respect to the Permitted Investment (less the cost of disposition, if any) (B) and the initial amount of the Permitted Investment, plus (iv) in the event that any Unrestricted Subsidiary is redesignated as a Restricted Subsidiary, the lesser of (A) an amount equal to the fair market value of the Investments in the Subsidiary previously made by Tri-Union and its Restricted Subsidiaries as of the date of the redesignation and (B) the amount of the Investments, plus (v) $1,000,000. (2) The provisions of the preceding paragraph (1) shall not prohibit: (a) the payment of any dividend within 60 days after the date of declaration of the dividend if the dividend would have been permitted on the date of declaration; (b) if no Default or Event of Default shall have occurred and be continuing, the acquisition of any shares of Capital Stock (other than Disqualified Stock) of Tri-Union or any Restricted 78 Subsidiary, either (i) solely in exchange for shares of Capital Stock of Tri-Union (other than Disqualified Stock) or (ii) through the application of net cash proceeds of a substantially concurrent sale for cash (other than to a Restricted Subsidiary) of shares of Capital Stock (other than Disqualified Stock) of Tri-Union; (c) if no Default or Event of Default shall have occurred and be continuing, the acquisition or retirement for value of any Subordinated Obligations (other than Disqualified Stock) of Tri-Union or a Subsidiary Guarantor either: (i) solely in exchange for shares of Capital Stock (other than Disqualified Stock) of Tri-Union; (ii) through the application of net cash proceeds of a substantially concurrent sale for cash (other than to a Restricted Subsidiary) of shares of Capital Stock (other than Disqualified Stock) of Tri-Union; or (iii) through Refinancing Indebtedness that also constitutes Subordinated Obligations; or (d) net advances to Richard Bowman and his Affiliates, excluding Tri-Union and the Restricted Subsidiaries, provided that any net advances in excess of $150,000 shall not be outstanding for more than 30 consecutive days. Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries Tri-Union will not, and will not cause or permit any of the Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to: (1) pay dividends or make any other distributions on or in respect of its Capital Stock; (2) make loans or advances, or pay any Indebtedness or other obligation owed, to Tri-Union or any Restricted Subsidiary; (3) guarantee the Notes, the Approved Hedge Agreements or any Hedge Liquidity Agreement; (4) transfer any of its property or assets to Tri-Union or any other Restricted Subsidiary; or (5) grant Liens on its property or assets to secure the Obligations, the Approved Hedge Agreements or any Hedge Liquidity Agreement (each such encumbrance or restriction, a "Payment Restriction"). The preceding will not apply to encumbrances or restrictions existing under or by reason of the following: (1) applicable law; (2) the indenture or any Security Document; (3) customary non-assignment provisions of any contract or any lease governing a leasehold interest of Tri-Union or any Restricted Subsidiary; (4) any instrument governing Acquired Indebtedness, provided that the restriction is limited only to the properties or assets the subject of such Capital Lease, mortgage or purchase money financing; (5) agreements existing on the Closing Date to the extent and in the manner such agreements were in effect on the Closing Date; 79 (6) customary restrictions with respect to a Restricted Subsidiary pursuant to an agreement that has been entered into for the sale or disposition of Capital Stock or assets of the Restricted Subsidiary to be consummated in accordance with the terms of the indenture solely in respect of the assets or Capital Stock to be sold or disposed of; (7) any instrument governing a Permitted Lien, only to the extent the instrument restricts the transfer or other disposition of assets subject to the Permitted Lien; (8) an agreement governing Refinancing Indebtedness incurred to Refinance the Indebtedness issued, assumed or incurred pursuant to an agreement referred to in clause (2), (4) or (5) above; provided that the provisions relating to such encumbrance or restriction contained in any such Refinancing Indebtedness are no less favorable to the Holders in any material respect as determined by the Board of Directors of Tri-Union in its reasonable and good faith judgment than the provisions relating to such encumbrance or restriction contained in the applicable agreement referred to in clause (2), (4) or (5); and (9) any instrument governing a Working Capital Revolver, only to the extent the instrument restricts the transfer or other disposition of accounts receivable, related general intangibles and related proceeds of Tri-Union and the Restricted Subsidiaries securing the Working Capital Revolver. Limitation on Sales of Assets (1) Tri-Union will not, and will not cause or permit any of the Restricted Subsidiaries to, consummate an Asset Disposition unless: (a) Tri-Union or the relevant Restricted Subsidiary, as the case may be, receives consideration at least equal to the fair market value of the assets sold or otherwise disposed of, as determined in good faith by the Board of Directors of Tri-Union; and (b) at least 70% of the consideration received by Tri-Union or the Restricted Subsidiary shall be in the form of cash or Temporary Cash Investments and is received at the time of the disposition. Within 270 days after an Asset Disposition, Tri-Union or the Restricted Subsidiary shall apply or cause to be applied the Net Available Cash of the Asset Disposition as follows: Tri-Union shall make an offer to purchase (the "Excess Proceeds Offer") from the Holders, on a pro rata basis, an aggregate stated principal amount of Notes equal to the Excess Proceeds (rounded down to the nearest multiple of $1,000) at a purchase price equal to the Accreted Value of the Notes, together with accrued interest (if any) to the date of purchase (the "Excess Proceeds Payment"); provided that Tri-Union will not be required to apply the Net Available Cash from any Asset Disposition pursuant to this clause if, and only to the extent that the Net Available Cash is applied to, within 270 days of the Asset Disposition: (a) an Investment or Investments in Additional Assets; (b) an Investment or Investments in properties or assets that replace the properties or assets that were the subject of the Asset Disposition (the "Replacement Assets"), and the assets constituting the Additional Assets or Replacement Assets and any non-cash consideration received are made subject to the Lien of the indenture and the Security Documents in accordance with the covenant described under the heading "-- Lien on Additional Collateral"; or (c) to the extent the Net Available Cash is received from an Asset Disposition not involving the sale, transfer or disposition of Collateral, to repay any Indebtedness secured by the assets involved in the Asset Disposition together with a concomitant permanent reduction in the amount of the Indebtedness so repaid; 80 provided that the use of Net Available Cash shall not exceed $7,000,000 in any one year. For purposes of this paragraph, "Excess Proceeds" means any Net Available Cash from Asset Dispositions remaining after investments in any Additional Assets or Replacement Assets as provided for in the preceding sentence. Tri-Union may defer the Excess Proceeds Offer until there are aggregate unutilized Excess Proceeds equal to or in excess of $5,000,000 resulting from one or more Asset Dispositions, at which time the entire unutilized Excess Proceeds, and not just the amounts in excess of $5,000,000, shall be applied as required pursuant to the preceding paragraph. Notwithstanding the foregoing, in the event that Tri-Union or any of the Restricted Subsidiaries consummates or causes to be consummated a single or a series of related Asset Dispositions representing more than 20% of the consolidated proved reserves of Tri-Union and the Restricted Subsidiaries (a "Major Asset Sale"), Tri-Union shall make an offer to purchase (the "Major Asset Sale Offer") from the Holders on a pro rata basis an aggregate stated principal amount of Notes equal to 50% of the gross proceeds from the Major Asset Sale at a purchase price equal to 100% of the stated principal amount of the Notes, together with accrued interest to the date of purchase. Any Net Available Cash remaining following the completion of the Major Asset Sale Offer shall be applied to, within 270 days of the date of completion of the Major Asset Sale Offer, an Investment or Investments in Additional Assets or Replacement Assets. Notice of an Excess Proceeds Offer or Major Asset Sale Offer shall comply with the procedures set forth in the indenture. Upon receiving notice of the Excess Proceeds Offer or Major Asset Sale Offer, Holders may elect to tender their Notes in whole or in part in integral multiples of $1,000 principal amount in exchange for cash. To the extent Holders properly tender Notes in an amount exceeding the Net Available Cash, Notes of tendering Holders will be repurchased on a pro rata basis (based on amounts tendered). (2) In the event of the transfer of substantially all, but not all, the property and assets of Tri-Union as an entirety to a Person in a transaction not constituting a Change of Control, the Successor Company shall be deemed to have sold the properties and assets of Tri-Union not so transferred, and shall comply with the provisions of this covenant with respect to the deemed sale as if it were an Asset Disposition and the Successor Company shall be deemed to have received Net Available Cash in an amount equal to the fair market value, as determined in good faith by the Board of Directors of Tri-Union, of the properties and assets not so transferred or sold. (3) All Net Available Cash shall constitute Trust Moneys and shall be delivered by Tri-Union to the Collateral Agent and shall be deposited in the Collateral Account in accordance with the Intercreditor Agreement. Net Available Cash so deposited may be withdrawn from the Collateral Account for application by Tri-Union in accordance with this covenant or otherwise pursuant to the indenture as described under the heading "-- Possession, Use and Release of Collateral -- Deposit, Use and Release of Trust Moneys." Limitation on Affiliate Transactions (1) Tri-Union shall not, and shall not permit any Restricted Subsidiary to, enter into or permit to exist any transaction with any Affiliate of Tri-Union (an "Affiliate Transaction") unless the terms of the transaction: (a) are no less favorable to Tri-Union or the Restricted Subsidiary than those that could be obtained at the time of the transaction in arm's-length dealings with a Person who is not an Affiliate; (b) if the Affiliate Transaction involves an amount between $500,000 and $3,000,000, are certified in an officers' certificate to the effect that the Affiliate Transaction complies with this covenant, and have been approved by a majority of the members of the Board of Directors of Tri-Union having no personal stake in the Affiliate Transaction; or 81 (c) if the Affiliate Transaction involves an amount in excess of $3,000,000, are certified in an officers' certificate to the effect that the Affiliate Transaction complies with this covenant, has been approved by a majority of the members of the Board of Directors of Tri-Union having no personal stake in the Affiliate Transaction and has been determined by a nationally recognized investment banking firm to be fair, from a financial standpoint, to Tri-Union or the Restricted Subsidiary, as the case may be. In addition, the net balance of advances made by Tri-Union and the Restricted Subsidiaries to Richard Bowman and his Affiliates shall not exceed $150,000 for more than 30 consecutive days. (2) The provisions of the preceding paragraph (1) shall not prohibit: (a) reasonable fees and compensation paid to and indemnity provided on behalf of, officers, directors, employees or consultants of Tri-Union or any Restricted Subsidiary as determined in good faith by the Board of Directors of Tri-Union; (b) transactions exclusively between or among the Restricted Subsidiaries; provided that the transactions are not otherwise prohibited by the indenture; and (c) Restricted Payments permitted by the indenture. Change of Control Upon the occurrence of a Change of Control, each Holder shall have the right to require that Tri-Union repurchase its Notes at a purchase price in cash equal to 101% of the stated principal amount of the Notes, together with accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders on the relevant record date to receive interest on the relevant interest payment date), in accordance with the terms contemplated below. Within 30 days following any Change of Control, Tri-Union shall mail a notice to each Holder with a copy to the trustee stating: (1) that a Change of Control has occurred and that the Holder has the right to require Tri-Union to purchase its Notes at a purchase price in cash equal to 101% of the stated principal amount of the Notes, together with accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders on the relevant record date to receive interest on the relevant interest payment date); (2) the circumstances and relevant facts regarding the Change of Control, including information with respect to pro forma historical income, cash flow and capitalization after giving effect to the Change of Control; (3) the repurchase date, which shall be no earlier than 30 days nor later than 60 days from the date the notice is mailed; and (4) the instructions determined by Tri-Union, consistent with this covenant, that a Holder must follow in order to have its Notes purchased. Tri-Union shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to this covenant. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this covenant, Tri-Union shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this covenant by virtue thereof. The Change of Control purchase feature is a result of negotiations between Tri-Union and Jefferies. Management has no present intention to engage in a transaction involving a Change of Control, although it is possible that Tri-Union would decide to do so in the future. Subject to the limitations discussed below, Tri-Union could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control 82 under the indenture, but that could increase the amount of Indebtedness outstanding at the time or otherwise affect Tri-Union's capital structure or credit ratings. Restrictions on the ability of Tri-Union to incur additional Indebtedness are contained in the covenants described under the heading "-- Limitation on Indebtedness," "-- Limitation on Liens" and "-- Limitation on Synthetic Leases." Except for the limitations contained in such covenants, the indenture will not contain any covenants or provisions that may afford Holders protection in the event of a highly leveraged transaction. The provisions under the indenture relating to Tri-Union's obligation to make an offer to repurchase the Notes as a result of a Change of Control or Asset Disposition may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes. Tri-Union will not be required to make an offer to purchase the Notes as a result of a Change of Control if a third party: (1) makes the offer in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to Tri-Union and (2) purchases all Notes validly tendered and not withdrawn under the an offer. Limitation on the Sale or Issuance of Capital Stock of Restricted Subsidiaries Tri-Union shall not sell or otherwise dispose of any shares of Capital Stock of a Restricted Subsidiary, and shall not permit any Restricted Subsidiary, directly or indirectly, to issue or sell or otherwise dispose of any shares of its Capital Stock except: (1) to Tri-Union or a Wholly Owned Subsidiary; (2) if all shares of Capital Stock of the Restricted Subsidiary (other than Tri-Union) are sold or otherwise disposed of; or (3) to the extent the shares represent directors' qualifying shares or shares required by applicable law to be held by a Person other than Tri-Union or a Restricted Subsidiary; provided that in the case of clause (2), Tri-Union complies with the provisions of the covenant described under the heading "-- Limitation on Sales of Assets" and provided further, Tri-Union shall not sell or otherwise dispose of any Capital Stock of Tri-Union. If Tri-Union or a Restricted Subsidiary shall dispose of all of the Capital Stock of any Subsidiary Guarantor, the Subsidiary Guarantor shall be released from the obligations under its Subsidiary Guarantee. Limitation on Liens Tri-Union will not, and will not cause or permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, assume or permit or suffer to exist or remain in effect any Liens other than Permitted Liens. Limitation on Synthetic Leases Tri-Union shall not, and shall not permit any Restricted Subsidiary to, enter into any Synthetic Lease Transaction with respect to any property unless: (1) Tri-Union or the Restricted Subsidiary would be entitled to Incur Indebtedness in an amount equal to the Attributable Debt with respect to the Synthetic Lease pursuant to the covenant described under the heading "-- Limitation on Indebtedness;" (2) the net cash proceeds received by Tri-Union or any Restricted Subsidiary in connection with the Synthetic Lease are at least equal to the fair value, as determined by the Board of Directors of Tri-Union of the property; and 83 (3) Tri-Union or the Restricted Subsidiary shall apply or cause to be applied the proceeds of the transaction in compliance with the covenant described under the heading "-- Limitation on Sales of Assets." Future Subsidiary Guarantors Tri-Union shall cause each of its Subsidiaries which is or becomes a Restricted Subsidiary to execute an Assumption Agreement required by the Guaranty Agreement. Merger and Consolidation Tri-Union shall not consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all its assets to, any Person, unless: (1) Tri-Union shall be the resulting, surviving or transferee corporation (the "Successor Company"); (2) the Successor Company, if not Tri-Union, shall expressly assume by a supplemental indenture, in a form acceptable to the trustee, all the obligations of Tri-Union under the indenture and the Security Documents; (3) immediately after giving effect to the transaction on a pro forma basis, and treating any Indebtedness which becomes an obligation of the Successor Company as a result of the transaction as having been issued by the Person at the time of the transaction, no Default shall have occurred and be continuing; (4) immediately after giving effect to the transaction, the Successor Company would be able to Incur an additional $1.00 of Indebtedness pursuant to paragraph (1) of the covenant described under the heading "-- Limitation on Indebtedness"; (5) immediately after giving effect to the transaction, the Successor Company shall have Consolidated Net Worth in an amount that is not less than the Consolidated Net Worth of Tri-Union immediately prior to the transaction; and (6) Tri-Union delivers to the trustee an officers' certificate and an opinion of counsel, each stating that the consolidation, merger or transfer and the supplemental indenture, if any, complies with the indenture. The Successor Company shall be the successor to Tri-Union and shall succeed to, and be substituted for, and may exercise every right and power of, Tri-Union under the indenture. SEC Reports Notwithstanding that Tri-Union may not at any time be subject to the reporting requirements of Section 13 or 15 of the Exchange Act, Tri-Union shall provide the trustee and the Holders, in each case within 15 days after the time periods specified for the filings in the SEC's rules and regulations: (1) all quarterly and annual financial information that would be required to be contained in a filing by Tri-Union with the SEC on Forms 10-Q and 10-K if Tri-Union were required to file such form, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual information only, a report on the annual financial statements by Tri-Union certified independent accountants; and (2) all current reports that would be required to be filed with the SEC on Form 8-K if Tri-Union were required to file the reports; provided that after the date that the Exchange Offer Registration Statement or the Shelf Registration Statement, as the case may be, is due to be filed, and notwithstanding that Tri-Union may not be 84 subject to the reporting requirements of Section 13 or 15 of the Exchange Act, Tri-Union will file with the SEC, to the extent permitted, and provide the trustee and the Holders with the annual and quarterly reports and the information, documents and other reports specified in Sections 13 and 15(d) of the Exchange Act. Limitation on Impairment of Lien Neither Tri-Union nor any of its Affiliates will take or omit to take any action which action or omission would have the result of adversely affecting or impairing the Lien in favor of the Collateral Agent, on behalf of itself, the Approved Hedge Counterparties or Hedge Liquidity Providers, as applicable, the trustee and the Holders or the priority thereof, with respect to the Collateral, and neither Tri-Union nor any of its Affiliates shall grant to any Person, or suffer any Person, other than Tri-Union and the Restricted Subsidiaries, to have (other than to the Collateral Agent on behalf of the Approved Hedge Counterparties or Hedge Liquidity Providers, as applicable, the trustee and the Holders) any interest whatsoever in the Collateral other than Permitted Liens. Neither Tri-Union nor any of the Restricted Subsidiaries will enter into any agreement or instrument that by its terms requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness, other than pursuant to the indenture and the Security Documents. Limitation on Conduct of Business Tri-Union will not, and will not permit any of the Restricted Subsidiaries to, engage in the conduct of any business other than the oil and gas business. Lien on Additional Collateral (1) If, after the Closing Date, Tri-Union or any of the Restricted Subsidiaries shall (a) acquire any oil and gas assets or other assets as non-cash consideration for any Asset Disposition or (b) engage in successful drilling and exploration activities resulting in the creation of new proved oil and gas reserves having a PV-10 Value in excess of $500,000, then Tri-Union shall, and shall cause each of the Restricted Subsidiaries to, execute and file in the appropriate filing offices additional Security Documents granting to the Collateral Agent for the benefit of the Approved Hedge Counterparties or Hedge Liquidity Providers, as applicable, the trustee and the Holders a first Lien, subject only to Permitted Liens (or in the case of property securing Acquired Indebtedness, to the extent not prohibited by the terms of the instruments creating the Acquired Indebtedness, a junior Lien), as is necessary or appropriate to ensure that the Lien of the indenture and the Security Documents covers substantially all of the new assets. (2) On the date any oil and gas assets or interests in a Permitted Joint Venture shall be acquired in exchange for or replacement of any Collateral, Tri-Union shall, and shall cause each of the Restricted Subsidiaries to, execute and file in the appropriate filing offices additional Security Documents granting to the Collateral Agent, for the benefit of the Approved Hedge Counterparties or Hedge Liquidity Providers, as applicable, the trustee and the Holders, a first Lien, subject only to Permitted Liens (or in the case of property securing Acquired Indebtedness, to the extent not prohibited by the terms of the instruments creating the Acquired Indebtedness, a junior Lien), on the portion of the assets as is necessary to ensure that the Lien of the indenture and the Security Documents covers substantially all of the assets received in exchange or trade or on the interests in the Permitted Joint Venture. (3) In connection with any Security Documents executed and filed under clause (1) or (2), Tri-Union shall, and shall cause each Restricted Subsidiary to, comply with the terms of the Trust Indenture Act to the extent applicable. (4) On March 15th of each year that the Notes are outstanding, beginning with March 15, 2002, Tri-Union shall review the oil and gas assets of Tri-Union and the Restricted Subsidiaries as of the 85 preceding January 1st to ascertain whether substantially all of the oil and gas assets as of such January 1st are then subject to the Lien of the indenture and the Security Documents, provided that to the extent any such oil and gas assets secure Acquired Indebtedness, the discounted future net revenues attributable to the oil and gas assets may be excluded to the extent the instruments securing the Acquired Indebtedness prohibit the Incurrence of a Lien on the assets. If substantially all of the assets are not then subject to the Lien of the indenture and the Security Documents, then Tri-Union shall, and shall cause the Restricted Subsidiaries to, execute and file in the appropriate filing offices additional Security Documents granting to the Collateral Agent for the benefit of the Approved Hedge Counterparties or Hedge Liquidity Providers, as applicable, the trustee and the Holders a first Lien, subject only to Permitted Liens (or in the case of property securing Acquired Indebtedness, to the extent not prohibited by the terms of instruments creating the Acquired Indebtedness, a junior Lien), as is necessary or appropriate to encumber substantially all the assets. Reserve Reports Not later than March 15 of each year, commencing March 15, 2002, Tri-Union shall furnish to the trustee a Reserve Report that (a) evaluates the oil and gas assets of Tri-Union and the Restricted Subsidiaries as of the immediately preceding January 1st, and (b) sets forth the projected production from proved producing properties for each month during the period commencing on such March 15 and ending 36 months after such date, for both crude oil and natural gas production, individually, and in the aggregate on an Mcfe basis. In addition, not later than 30 days following any acquisition or exchange, or series of such transactions, of any oil and gas assets having aggregate volumes of proved developed producing reserves in excess of 20% of the aggregate proved producing reserves set forth in the most recently delivered Reserve Report, Tri-Union shall furnish to the trustee a supplemental Reserve Report pertaining to the oil and gas assets acquired in the exchange. Each such Reserve Report of each year shall be prepared by certified independent petroleum engineers or other independent petroleum consultant(s) of recognized national standing. Hedging Obligations Tri-Union and/or a Restricted Subsidiary will enter into and maintain oil and gas Hedging Contracts with an Approved Hedge Counterparty pursuant to which Tri-Union and/or a Restricted Subsidiary will receive a fixed price payment or a minimum floor price so that at all times to July 1, 2006, Tri-Union and/or a Restricted Subsidiary will have a Hedged Revenue Ratio of not less than 3.0 to 1.0 as of the first business day of each month for the then current Hedge Period; provided that: (1) in no event shall Tri-Union and/or a Restricted Subsidiary enter into oil and gas hedging contracts that, when in effect, hedge aggregate volumes in excess of 80% of (a) the Projected Proved Developed Producing Production of each of crude oil and natural gas and (b) the Projected Proved Developed Producing Production of both crude oil and natural gas, in each case, from the oil and gas assets of Tri-Union and/or the Restricted Subsidiaries for the then current Hedge Period and each month in the then current Hedge Period, except that Tri-Union and/or a Restricted Subsidiary may enter into oil and gas hedging contracts which are price floor contracts, options for a price floor or other similar arrangements (and for which neither Tri-Union nor any Restricted Subsidiary has any liability other than the payment of an initial premium price) which, with all oil and gas hedging contracts then in effect, result in the aggregate volumes exceeding 80%, but in no event in excess of 100%, of the Projected Proved Developed Producing Production of each of oil and natural gas of Tri-Union and the Restricted Subsidiaries; (2) any oil and gas hedging contract executed pursuant to this covenant may be terminated, for any reason, without violation of this covenant if either (a) termination is required pursuant to clause (4) below or (a) a replacement oil and gas hedging contract with an Approved Hedge Counterparty is entered into such that, after giving effect to the termination and the execution 86 and delivery of the replacement oil and gas hedging contract, the Hedged Revenue Ratio is not less than 3.0 to 1.0, subject to clause (1) of this covenant; (3) if, as of any date of determination, NYMEX prices available for natural gas (Henry Hub) and crude oil (West Texas Intermediate) are less than $2.75 per MMBtu of natural gas (Henry Hub) or $18.00 per barrel of crude oil (West Texas Intermediate) for the one or more months during the then current Hedge Period (such period during which such prices are not available being the "Make-Up Period"), then the Hedged Revenue Ratio shall not be tested during the Make-Up Period, and as soon thereafter as available hedge prices for the Make-Up Period or any month during the Make-Up Period exceed the relevant minimum levels, then Tri-Union and/or a Restricted Subsidiary shall be required to have a Hedged Revenue Ratio for the then current Hedge Period of not less than 3.0 to 1.0, subject to clause (1) of this covenant; and (4) in the event of any sale, exchange or other disposition of oil and gas assets by Tri-Union and/or any Restricted Subsidiary, Tri-Union and/or a Restricted Subsidiary shall calculate its Hedged Revenue Ratio on a pro forma basis (to exclude the oil and gas asset disposed of utilizing the Projected Proved Developed Producing Production for the asset reflected in the most recently delivered Reserve Report) as of the first day of the month during which the sale, exchange or other disposition occurred for the Hedge Period commencing on such date and shall either (a) be in compliance with this covenant as of such day for the entirety of the Hedge Period or (b) terminate one or more oil and gas hedging contracts such that after giving effect to the termination, it would be in compliance with this covenant. Notwithstanding anything herein to the contrary, Tri-Union and/or a Restricted Subsidiary will enter into oil and gas hedging contracts for ordinary business purposes, to hedge their and the Restricted Subsidiaries' actual exposure to fluctuations in commodity prices and not for speculative purposes. It is the intention of the parties that if (a) as of the first business day of each month for the then current Hedge Period the Hedged Revenue Ratio is less than 3.0 to 1.0, and (b) a Reserve Report is delivered which indicates an increase in the Projected Proved Producing Production for any month or months in the then current Hedge Period or in the aggregate Projected Proved Producing Production, then Tri-Union and/or a Restricted Subsidiary shall be obligated to enter into and maintain incremental oil and gas hedging contracts with an Approved Hedge Counterparty to hedge incremental volumes such that it has either met the minimum Hedge Revenue Ratio of 3.0 to 1.0 or hedged the maximum amount of revenue for each month in the then current Hedge Period possible without violating the volume caps set forth in clause (1) of this covenant. Excess Cash Flow Offer On the 45th day following the end of each fiscal quarter, commencing with the quarter ended June 30, 2004, Tri-Union shall calculate its Excess Cash Flow for the most recently ended fiscal quarter, certify to the trustee in writing the calculations to compute the Excess Cash Flow, and if Tri-Union has Excess Cash Flow of at least $1,000,000, Tri-Union will make an offer (an "Excess Cash Flow Offer") to purchase Notes at 100% of the aggregate principal amount of the Notes, plus accrued interest, to the date of purchase; provided that the amount required to be paid by Tri-Union to repurchase the Notes shall be limited to an amount equal to 50% of the Excess Cash Flow. Tri-Union must commence its Excess Cash Flow Offer not later than the date on which the certificate computing the Excess Cash Flow is delivered to the trustee. If the aggregate purchase price for the Notes, exclusive of interest, tendered pursuant to the Excess Cash Flow Offer is less than the Excess Cash Flow, then Tri-Union and the Restricted Subsidiaries may use the remaining Excess Cash Flow for general corporate purposes not prohibited by the terms of the indenture. Each Excess Cash Flow Offer shall remain open for a period of 20 Business Days, unless a longer period is required by law (the "Excess Cash Flow Offer Period"). Promptly after the 87 termination of the Excess Cash Flow Period (the "Excess Cash Flow Payment Date"), Tri-Union shall purchase and mail or deliver payment for the Notes or portions of the Notes tendered pro rata or by such other method as may be required by law. Tri-Union shall make a public announcement of the results of the Excess Cash Flow Offer as soon as practicable after the Excess Cash Flow Payment Date. Independent Board of Tri-Union Within 45 days of the Closing Date, the Board of Directors of Tri-Union shall consist of at least three directors, at least 60% of whom shall be Independent Directors, and the composition of the Board of Directors shall be maintained so long as any of the Notes remain outstanding. Until a Board of Directors meeting the requirements of this covenant shall have been appointed, Tri-Union and the Restricted Subsidiaries shall not engage in any activities requiring the approval of the Board of Directors of Tri-Union under the terms of the indenture except for the transactions disclosed in this prospectus. Jefferies shall have the right to require that Tri-Union cause to be appointed to its Board of Directors a person designated by Jefferies for so long as any of the Notes remain outstanding. Exploration Costs Tri-Union and the Restricted Subsidiaries shall not incur exploration costs (as reported in the supplemental oil and natural gas information in Tri-Union's annual financial statements in accordance with GAAP) in excess of $10,000,000 in any fiscal year. DEFAULTS An "Event of Default" is defined in the indenture as: (1) a default in the payment of interest on the Notes when due, continued for 30 days; (2) a default in the payment of principal of any Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise; (3) the failure by Tri-Union to comply with its obligations described under the heading "-- Certain Covenants -- Merger and Consolidation" or the failure by any Subsidiary Guarantor to comply with its obligations described in the final paragraph under the heading "-- Guarantees;" (4) the failure by Tri-Union or any Restricted Subsidiaries to comply for 30 days after notice from the trustee or any Holder with any of its obligations, if any, in the covenants described under the heading "-- Certain Covenants -- Limitation on Indebtedness," "-- Limitation on Restricted Payments," "-- Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries," "-- Limitation on Sales of Assets" (other than a failure to purchase Notes), "-- Limitation on Affiliate Transactions," "-- Limitation on the Sale or Issuance of Capital Stock of Restricted Subsidiaries," "-- Change of Control," "-- Limitation on Liens," "-- Limitation on Synthetic Leases," "-- Future Subsidiary Guarantors," "-- SEC Reports," "-- Limitation on Impairment of Lien," "-- Limitation on Conduct of Business," "-- Lien on Additional Collateral," "-- Reserve Reports," "-- Hedging Obligations," "-- Excess Cash Flow Offer," "-- Independent Board of Tri-Union," or "Exploration Costs;" (5) the failure by Tri-Union or any Subsidiary Guarantor to comply for 60 days after notice from the trustee or any Holder with its other agreements contained in the indenture or any Security Document; (6) principal of, or interest on, any Indebtedness of Tri-Union or any Restricted Subsidiary in excess of $5,000,000 is not paid when due, after giving effect to any applicable grace period, or any default shall occur and be continuing under any Indebtedness of Tri-Union or any Restricted 88 Subsidiary in excess of $5,000,000 and the maturity thereof is accelerated by the holders thereof (the "cross acceleration provision"); (7) certain events of bankruptcy, insolvency or reorganization of Tri-Union or a Restricted Subsidiary (the "bankruptcy provisions"); (8) any judgment or decree for the payment of money in excess of $5,000,000 is rendered against Tri-Union or a Restricted Subsidiary, remains outstanding for a period of 60 days following the judgment and is not discharged, waived or stayed within 10 days after notice from the trustee or any Holder (the "judgment default provision"); (9) the Guaranty Agreement or any Security Document ceases to be in full force and effect (other than in accordance with the terms of the Guaranty Agreement or the Security Document) or Tri-Union or a Subsidiary Guarantor denies or disaffirms its obligations under any Security Document to which it is a party or the Guaranty Agreement, as applicable, if the default continues for a period of 10 days after notice from the trustee or any Holder thereof to Tri-Union; or (10) a material breach of any of the representations or warranties contained in any Security Document or in the indenture or a material misstatement in any certification provided pursuant to any Security Document or the indenture. However, a default under clauses (4), (5), (8) and (10) will not constitute an Event of Default until the trustee or the Holders of 25% in principal amount of the outstanding Notes notify Tri-Union of the default and Tri-Union or the relevant Subsidiary Guarantor does not cure the default within the time specified after receipt of the notice. If an Event of Default occurs and is continuing, the trustee or the Holders of at least 25% in principal amount of the outstanding Notes may declare the principal of and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, the principal and interest shall be due and payable immediately. If an Event of Default relating to the bankruptcy provisions occurs and is continuing, the principal of and interest on all the Notes will ipso facto become and be immediately due and payable without any declaration or other act on the part of the trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any acceleration with respect to the Notes and its consequences. Subject to the provisions of the indenture relating to the duties of the trustee, if an Event of Default occurs and is continuing, the trustee will be under no obligation to exercise any of the rights or powers under the indenture at the request or direction of any of the Holders unless the Holders have offered to the trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal or interest when due, no Holder may pursue any remedy with respect to the indenture, the Notes or any Subsidiary Guarantee unless: (1) the Holder has previously given the trustee notice that an Event of Default is continuing; (2) Holders of at least 25% in principal amount of the outstanding Notes have requested the trustee to pursue the remedy; (3) the Holders have offered the trustee reasonable security or indemnity against any loss, liability or expense; (4) the trustee has not complied with the request within 60 days after the receipt of the request and the offer of security or indemnity; and (5) the Holders of a majority in principal amount of the outstanding Notes have not given the trustee a direction inconsistent with the request within the 60-day period. Subject to certain restrictions, the Holders of a majority in principal amount of the outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any 89 remedy available to the trustee or of exercising any trust or power conferred on the trustee. The trustee, however, may refuse to follow any direction that conflicts with law or the indenture or that the trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the trustee in personal liability. No Holder may enforce any right or remedy provided in any other Security Document. Such rights and remedies will be enforced by the Collateral Agent subject to the terms of the Intercreditor Agreement. If a Default occurs and is continuing and is known to the trustee, the trustee must mail to each Holder notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Note, the trustee may withhold notice if and so long as a committee of its trust officers determines that withholding notice is not opposed to the interest of the Holders. In addition, Tri-Union is required to deliver to the trustee, within 120 days after the end of each fiscal year, an officers' certificate indicating whether the signer of the certificate knows of any Default that occurred during the fiscal year. Tri-Union also is required to deliver to the trustee, within 30 days after the occurrence thereof, written notice of any event which would constitute certain Defaults, their status and what action Tri-Union is taking or proposes to take in respect thereto. AMENDMENTS AND WAIVERS Subject to certain exceptions, the indenture may be amended with the consent of the Holders of a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange for the Notes) and any past default or noncompliance with any provisions may also be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding. However, without the consent of each Holder of an outstanding Note affected thereby, no amendment may, among other things: (1) reduce the amount of Notes whose Holders must consent to an amendment; (2) reduce the rate of or extend the time for payment of interest on any Note; (3) reduce the principal of or extend the Stated Maturity of any Note; (4) reduce the premium payable upon the redemption of any Note or change the time at which any Note may be redeemed; (5) make any Note payable in any currency other than that stated in the Note; (6) impair the right of any Holder to receive payment of principal of and interest and any additional interest on the Holder's Notes on or after the due dates therefor (other than a payment required by one of the covenants described above under the heading "-- Certain Covenants -- Limitation on Sales of Assets" or "-- Change of Control") or to institute suit for the enforcement of any payment on or with respect to the Holder's Notes; (7) make any change in the amendment provisions which require each Holder's consent or in the waiver provisions; (8) make any change in any Subsidiary Guarantee or any Security Document that could adversely affect the Holder; or (9) release any Collateral from the Liens created pursuant to the indenture and the Security Documents or release any Subsidiary Guarantor from any of its obligations under the indenture or the Guaranty Agreement, as the case may be, in any case otherwise than in accordance with the terms of the indenture, the Guaranty Agreement and the Security Documents. Without notice to or the consent of any Holder, the trustee, Tri-Union and the Subsidiary Guarantors may amend the indenture to cure any ambiguity, omission, defect or inconsistency, to provide for the assumption by a Successor Company of the obligations of Tri-Union or a Subsidiary Guarantor under the indenture, the Security Documents or the Guaranty Agreement, as the case may be, to provide for uncertificated Notes in addition to or in place of certificated Notes, to make 90 any change that does not adversely affect the rights of any Holder or to comply with any requirement of the SEC in connection with the qualification of the indenture under the Trust Indenture Act. The consent of the Holders is not necessary under the indenture to approve the particular form of any proposed amendment. It is sufficient if the consent approves the substance of the proposed amendment. Amendments, modifications, supplements, waivers, consents and approvals of or in connection with the Guaranty Agreement, the Intercreditor Agreement and any Security Document may be effectuated only upon the written consent of each of the Approved Hedge Counterparties then a party thereto, Hedge Liquidity Providers having greater than 50% of the aggregate commitments of the Hedge Liquidity Providers if a Hedge Liquidity Agreement is in place and Holders having 50% or more of the outstanding principal amount of the then outstanding principal amount of the Notes (and, if the rights or duties of the Collateral Agent or the trustee or any of the Issuer or Subsidiary Guarantors are affected thereby, by the Collateral Agent, the trustee, the Issuer or the applicable Subsidiary Guarantor, as the case may be); provided that (1) the provisions of the Intercreditor Agreement governing application of proceeds shall not be amended without the unanimous written consent of each creditor and, if the rights or duties of the Collateral Agent, the trustee or any of the Issuer or Subsidiary Guarantors are affected thereby, by the Collateral Agent, the trustee or the Issuer, or applicable Subsidiary Guarantor, as the case may be; (2) any waiver of Triggering Events, Releases of Collateral (except Asset Dispositions, Released Working Capital Revolver Interests and Releases of Collateral Account Assets in accordance with the terms of the Intercreditor Agreement) and any release of the Issuer, or any Subsidiary Guarantor requires approval of the Approved Hedge Counterparties; and (3) no Security Document may be amended if the effect of the amendment would be: (a) to secure additional obligations, other than additional Notes issued under the indenture, or any other obligations (b) to secure indebtedness or obligations owed in favor of any other creditor or groups of creditors; (c) to change the priority of or subordinate the Liens created thereby; (d) to modify any material remedy provided for therein; or (e) to cause the obligations owed to any Holder, Hedge Liquidity Provider or Approved Hedge Counterparty to not be equally and ratably secured thereby (subject to the priorities set forth herein). After an amendment under the indenture, the Guaranty Agreement or any Security Document becomes effective, Tri-Union is required to mail to Holders a notice briefly describing the amendment. However, the failure to give the notice to all Holders, or any defect therein, will not impair or affect the validity of the amendment. POSSESSION, USE AND RELEASE OF COLLATERAL Unless an Event of Default or a Termination Event under the indenture, the Approved Hedge Agreement or the Hedge Liquidity Agreements (the "Principal Agreements") shall have occurred and be continuing, Tri-Union and the Restricted Subsidiaries will have the right to remain in possession and retain exclusive control of the Collateral securing the Notes (other than any cash, securities, obligations and Temporary Cash Investments constituting part of the Collateral and deposited with the Collateral Agent in the Collateral Account and other than as set forth in the Security 91 Documents), to freely operate the Collateral and to collect, invest and dispose of any income thereon or therefrom. Release of Collateral Upon compliance by Tri-Union and the Restricted Subsidiaries with the conditions set forth in the indenture in respect of any sale, lease, transfer or other disposition to any Person involving Collateral (including the disposition of all of the Capital Stock of a Subsidiary Guarantor), the trustee will direct the Collateral Agent to release the Collateral from the Lien of the Security Documents and reconvey the Released Interests to the Collateral to Tri-Union or the relevant Restricted Subsidiary or such other Person as Tri-Union or the relevant Restricted Subsidiary may direct in writing. Tri-Union and the Restricted Subsidiaries will have the right to obtain a release of items of Collateral subject to any sale, lease, transfer or other disposition or owned by a Subsidiary Guarantor all of the Capital Stock of which is the subject of a disposition under limited circumstances. Upon compliance by Tri-Union and the Restricted Subsidiaries, with the conditions set forth in the indenture in respect of any instrument governing a Working Capital Revolver, to the extent and only to the extent the instrument involves the creation of Permitted Liens on accounts receivable, related general intangibles and related proceeds of Tri-Union and the Restricted Subsidiaries to secure Indebtedness Incurred under the Working Capital Revolver, the trustee will direct the Collateral Agent to release the Collateral from the Lien of the indenture and the Security Documents and reconvey the Collateral to Tri-Union or the Restricted Subsidiaries or such other Person as they may direct in writing. Tri-Union and the Restricted Subsidiaries will have the right to obtain a release of the accounts receivable, related general intangibles and related proceeds of Tri-Union and the Restricted Subsidiaries to secure Indebtedness Incurred under the Working Capital Revolver. Notwithstanding the provisions described under this heading "-- Release of Collateral," so long as no Event of Default or Termination Event under any of the Principal Agreements shall have occurred and be continuing or would result therefrom, Tri-Union or a Restricted Subsidiary may engage in any number of ordinary course activities in respect of the Collateral, in limited dollar amounts specified by the Trust Indenture Act, upon satisfaction of certain conditions. For example, among other things, subject to the dollar limitations and conditions, Tri-Union or a Restricted Subsidiary would be permitted to: (1) sell or otherwise dispose of any property subject to the Lien of the Security Documents, which may have become worn out or obsolete; (2) abandon, terminate, cancel, release or make alterations in or substitutions of any leases or contracts subject to the Lien of the Security Documents; (3) surrender or modify any franchise, license or permit subject to the Lien of the Security Documents which it may own or under which it may be operating; (4) alter, repair, replace, change the location or position of and add to its structures, machinery, systems, equipment, fixtures and appurtenances; (5) demolish, dismantle, tear down or scrap any Collateral or abandon any Collateral thereof; and (6) grant farm-outs, leases or sub-leases in respect of real property to the extent any of the preceding does not constitute an Asset Disposition. Deposit, Use and Release of Trust Moneys All Net Available Cash aggregating in excess of $1,000,000 in any fiscal year from any Asset Dispositions involving Collateral shall be deposited into a securities account maintained by the Collateral Agent at its corporate offices or at any securities intermediary selected by the trustee having a combined capital and surplus of at least $250,000,000 and having a long-term debt rating 92 of at least "A3" by Moody's Investors Service, Inc. and at least "A -- " by Standard & Poor's Ratings Services styled the "Tri-Union Collateral Account" (such account being the "Collateral Account") which shall be under the exclusive dominion and control of the Collateral Agent. All amounts on deposit in the Collateral Account shall be treated as financial assets and cash funds on deposit in the Collateral Account may be invested by the Collateral Agent, at the direction of Tri-Union, as applicable, in Temporary Cash Investments; provided, however, in no event shall Tri-Union have the right to withdraw funds or assets from the Collateral Account except in compliance with the terms of the Intercreditor Agreement and all assets credited to the Collateral Account shall be subject to a perfected, first priority Lien in favor of the Collateral Agent for the benefit of the Approved Hedge Counterparties or Hedge Liquidity Providers (as applicable), the trustee and the Holders. Any such funds will be released to Tri-Union by it delivering to the Collateral Agent and the trustee an officers' certificate stating that: (1) no Event of Default or Termination Event under any Principal Agreement has occurred and is continuing as of the date of the proposed release; (2) (a) if the Trust Moneys represent Net Available Cash subject to the covenant described under the heading "-- Certain Covenants -- Limitation on Sales of Assets" in respect of an Asset Disposition, that the funds will be applied in accordance with the covenant; or (b) if the Trust Moneys do not represent Net Available Cash, subject to the covenant described under the heading "-- Certain Covenants -- Limitation on Sales of Assets," that the amounts will be utilized in connection with the business of Tri-Union and the Restricted Subsidiaries in compliance with the terms of the Approved Hedging Agreements, the Hedge Liquidity Agreements (if applicable) and the indenture; (3) all other terms and conditions in the Approved Hedge Agreements, the Hedge Liquidity Agreements (if applicable) and the indenture relating to the release in question have been complied with; and (4) all documentation required by the Trust Indenture Act, if any, prior to the release of the Trust Moneys has been delivered to the Collateral Agent and the trustee. Notwithstanding the preceding, (1) if no Triggering Event has occurred and is continuing and Tri-Union so elects by giving written notice to the Collateral Agent, the Collateral Agent shall apply Trust Moneys credited to the Collateral Account to the payment of amounts due under any Approved Hedge Agreement (whether regularly scheduled payments or termination payments) or Hedge Liquidity Agreements (if applicable) or any Note, including interest due on any interest payment date, and (2) if Tri-Union so elects, by giving written notice to the Collateral Agent, the Collateral Agent shall, subject to the priorities set forth in the Intercreditor Agreement, apply Trust Moneys credited to the Collateral Account to the payment of amounts specified in the Intercreditor Agreement as being secured by the Collateral, including the principal of, and accrued and unpaid interest on, any Notes at their Stated Maturity or upon redemption or to the purchase of Notes upon tender or in the open market or at private sale or upon any exchange or in any one or more of such ways, in each case in compliance with the indenture and at the direction of Tri-Union. TRANSFER The Notes will be issued in registered form and will be transferable only upon the surrender of the Notes being transferred for registration of transfer. Tri-Union may require payment of a sum sufficient to cover any tax, assessment or other governmental charge payable in connection with certain transfers and exchanges. 93 DEFEASANCE Tri-Union at any time may terminate all its obligations under the Notes and the indenture and all of the obligations of the Subsidiary Guarantors under the Guaranty Agreement and the Indenture ("legal defeasance"), except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the Notes, to replace mutilated, destroyed, lost or stolen Notes and to maintain a Registrar and Paying Agent in respect of the Notes. Tri-Union at any time may terminate its obligations under the covenants described under the heading "-- Certain Covenants" (other than the covenant described under the heading "-- Certain Covenants -- Merger and Consolidation"), the operation of the cross acceleration provision, the bankruptcy provisions with respect to Restricted Subsidiaries and the judgment default provision described under the heading "-- Defaults" above and the limitations contained under "-- Certain Covenants -- Merger and Consolidation" above ("covenant defeasance"). Tri-Union may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If Tri-Union exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default with respect thereto. If Tri-Union exercises its covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in clause (4), (5), (6), (7) (with respect only to Restricted Subsidiaries) or (8) under the heading "-- Defaults" above or because of the failure to comply with the covenants under "-- Certain Covenants -- Merger and Consolidation" above. If Tri-Union exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor, if any, will be released from all its obligations with respect to its Guarantee and the Lien of the Security Documents will also be released. In order to exercise either defeasance option, Tri-Union must irrevocably deposit in trust (the "defeasance trust") with the trustee money or United States Government Obligations for the payment of principal and interest on the Notes to redemption or maturity, as the case may be, and must comply with certain other conditions, including delivery to the trustee of an opinion of counsel to the effect that Holders will not recognize income, gain or loss for federal income tax purposes as a result of the deposit and defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if the deposit and defeasance had not occurred (and, in the case of legal defeasance only, such opinion of counsel must be based on a ruling of the Internal Revenue Service or other change in applicable federal income tax law). CONCERNING THE TRUSTEE Firstar Bank, National Association, is to be the trustee under the indenture and has been appointed by Tri-Union as the initial Registrar and initial Paying Agent with regard to the Notes. The Holders of a majority in principal amount of the outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions and the terms of the Intercreditor Agreement. If an Event of Default occurs (and is not cured), the indenture requires that the trustee, in the exercise of its power, use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any Holder, unless the Holder shall have offered to the trustee security and indemnity satisfactory to it against any loss, liability or expense and then only to the extent required by the terms of the indenture. BOOK-ENTRY; DELIVERY AND FORM The Notes initially will be represented by one or more permanent global Notes in definitive, fully registered form without interest coupons (collectively, the "Global Note") and will be deposited with the trustee as custodian for, and registered in the name of, a nominee of DTC. 94 Ownership of beneficial interests in the Global Note will be limited to persons who have accounts with DTC ("participants") or persons who hold interests through participants. Ownership of beneficial interests in the Global Note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). So long as DTC, or its nominee, is the registered owner or holder of the Global Note, DTC or the nominee, as the case may be, will be considered the sole owner or holder of the Notes represented by the Global Note for all purposes under the indenture and the Notes. No beneficial owner of an interest in a Global Note will be able to transfer that interest except in accordance with DTC's applicable procedures, in addition to those provided for under the indenture and, if applicable, those of a participant through which the Note is held. Payments of the principal of, and interest on, the Global Note will be made to DTC or its nominee, as the case may be, as the registered owner of the Global Note. Neither Tri-Union, the trustee nor any Paying Agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Note or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests. Tri-Union expects that DTC or its nominee, upon receipt of any payment of principal or interest in respect of the Global Note, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Note as shown on the records of DTC or its nominee. Tri-Union also expects that payments by participants to owners of beneficial interests in the Global Note held through the participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for the customers. Such payments will be the responsibility of the participants. Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will to be settled in same-day funds. Tri-Union expects that DTC will take any action permitted to be taken by a Holder (including the presentation of Notes for exchange as described below) only at the direction of one or more participants to whose account the DTC interests in the Global Note is credited and only in respect of the portion of the aggregate principal amount of any Note as to which the participant or participants has or have given such direction. However, if there is an Event of Default under the Notes, DTC may exchange the applicable Global Note for certificated Notes, as discussed below under the heading "-- Certificated Notes," which it will distribute to its participants. Tri-Union understands that DTC is a limited purpose trust company organized under the laws of the State of New York, a "banking organization" within the meaning of New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the Uniform Commercial Code and a "Clearing Agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates and certain other organizations.

"Unrestricted Subsidiary" means: (1) any Subsidiary of Tri-Union that at the time of determination shall be designated an Unrestricted Subsidiary by the Board of Directors of Tri-Union in the manner provided below; and (2) any Subsidiary of an Unrestricted Subsidiary. The Board of Directors of Tri-Union may designate any Subsidiary of Tri-Union, including any newly acquired or newly formed Subsidiary, to be an Unrestricted Subsidiary unless the Subsidiary or any of its Subsidiaries owns any Capital Stock or Indebtedness of, or holds any Lien on any property of, Tri-Union or any other Subsidiary of Tri-Union that is not a Subsidiary of the Subsidiary to be so designated.

"Working Capital Revolver" means with respect to Tri-Union or any Restricted Subsidiary, one or more debt facilities or commercial paper facilities with banks or other institutional lenders providing for revolving working capital loans. PLAN OF DISTRIBUTION Each broker-dealer that receives new notes for its own account must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new notes received in exchange for old notes where such old notes were acquired as a 118 result of market-making activities or other trading activities. We have agreed, for a period of 180 days after consummation of the exchange offer, to make available a prospectus meeting the requirements of the Securities Act to any broker-dealer for use in connection with any resale of any publicly registered note acquired in the exchange offer. In addition, until , 2001 (90 days after the date of this prospectus), all dealers effecting transactions in the new notes may be required to deliver a prospectus. We will not receive any proceeds from any sales of new notes by broker-dealers. New notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the new notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of concessions from any such broker-dealer or the purchasers of any such new notes. Any broker-dealer that resells new notes that were received by it for its own account pursuant to the exchange offer and any broker-dealer that participates in a distribution of such new notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any such resale of new notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. We will furnish copies of the prospectus included in this registration statement, including any preliminary prospectus, and any amendment or supplement thereto, as any broker-dealer may reasonably request. We have agreed to pay all expenses incident to the exchange offer other than commissions or concessions of any brokers or dealers and will indemnify the holders of the old notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act. REGISTRATION RIGHTS Pursuant to a registration rights agreement, we agreed to file with the SEC a registration statement on the appropriate form under the Securities Act with respect to an offer to exchange the old notes for publicly registered new notes with substantially identical terms. Upon the effectiveness of the registration statement, we will offer to the holders of old notes who are able to make certain representations the opportunity to exchange their old notes for publicly registered notes. Such offer shall remain open for not less than 30 days (or longer if required by applicable law) after the date notice of the exchange offer is mailed to holders of the old notes. For each old note surrendered to us under the exchange offer, the holder will receive a publicly registered note of equal principal amount. Interest on each publicly registered note will accrue from the last interest payment date on which interest was paid on the old notes so surrendered or, if no interest has been paid on such notes, from the date of original issuance of the old notes. If we effect the exchange offer, we will be entitled to close the exchange offer 30 days after the commencement thereof, provided, however, that we have accepted all old notes previously and validly surrendered in accordance with the terms of the exchange offer. Old notes not tendered in the exchange offer, together with any publicly registered new notes will be treated as a single class of securities under the indenture. However, any old notes not tendered in the exchange offer will remain subject to the transfer restrictions originally placed on the old notes. If (i) we are not permitted to file the exchange offer registration statement or to consummate the exchange offer because the exchange offer is not permitted by applicable law or SEC policy or (ii) any holder of old notes notifies us within the specified time period that (A) due to a change in law or policy it is not entitled to participate in the exchange offer, (B) due to a change in law or policy it 119 may not resell the publicly registered notes acquired by it in the exchange offer to the public without delivering a prospectus and the prospectus contained in the exchange offer registration statement is not appropriate or available for such resales by holders or (C) it is a broker-dealer and owns old notes acquired directly from us or an affiliate of us, we will file with the SEC a shelf registration statement to cover resales of any transfer restricted notes (as described below) by the holders thereof, and we will use our best efforts to cause the applicable registration statement to be declared effective within specified periods by the SEC. For purposes of the foregoing, "transfer restricted notes" means each old note until (i) the date on which such note has been exchanged by a person other than a broker-dealer for a publicly registered note in the exchange offer, (ii) following the exchange by a broker-dealer in the exchange offer of an old note for a publicly registered note, the date on which such publicly registered note is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the exchange offer registration statement, (iii) the date on which such old note has been effectively registered under the Securities Act and disposed of in accordance with the shelf registration statement or (iv) the date on which such old note may be distributed to the public pursuant to Rule 144(k) under the Securities Act. Under existing SEC interpretations, any transfer restricted notes would, in general, be freely transferable by the holders (other than our affiliates) after the exchange offer without further registration under the Securities Act; provided, however, that in the case of broker-dealers participating in the exchange offer, a prospectus meeting the requirements of the Securities Act will be delivered upon resale by such broker-dealer in connection with resales of the publicly registered notes. We have agreed, for a period of 180 days after consummation of the exchange offer, to make available a prospectus meeting the requirements of the Securities Act to any such broker-dealer for use in connection with any resale of any publicly registered note acquired in the exchange offer. A broker-dealer which delivers such a prospectus to purchasers in connection with such resales will be subject to certain of the civil liability provisions under the Securities Act and will be bound by the provisions of the registration rights agreement (including certain indemnification rights and obligations). Each holder of the old notes who wishes to exchange such notes for publicly traded notes in the exchange offer will be required to make certain representations, including representations that (i) any publicly traded notes to be received by it will be acquired in the ordinary course of its business, (ii) it is not participating in, and it has no arrangement with any person to participate in the distribution (within the meaning of the Securities Act) of the publicly traded notes, (iii) it is not an "affiliate" of us, as defined in Rule 405 of the Securities Act, and (iv) it is not a broker-dealer tendering notes acquired directly from us for its own account. If the holder is a broker-dealer that will receive publicly traded notes for its own account in exchange for old notes that were acquired as a result of market-making activities or other trading activities, it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such publicly traded notes. The registration rights agreement provides that: (i) unless the exchange offer would not be permitted by applicable law or SEC policy, we will file an exchange offer registration statement with the SEC on or prior to 60 days after the date of original issuance of the old notes, (ii) unless the exchange offer would not be permitted by applicable law or SEC policy, we will use our best efforts to have the exchange offer registration statement declared effective by the SEC on or prior to 120 days after the date of original issuance of the old notes, (iii) unless the exchange offer would not be permitted by applicable law or SEC policy, we will commence the exchange offer and use our best efforts to issue, on or prior to 60 days after the date on which the exchange offer registration statement was declared effective by the SEC, publicly registered notes, in exchange for all old notes tendered prior thereto in the exchange offer and (iv) if obligated to file the shelf registration statement, we will file on or prior to the earlier of (x) 180 days after the date of original issuance of the old notes or (y) 30 days after such filing obligation arises and use our best efforts to cause the shelf registration statement to be declared effective by the SEC on or prior to 90 days after such 120 obligation arises; provided that if we have not consummated the exchange offer within 180 days of the date of original issuance of the old notes, then we will file the shelf registration statement with the SEC on or prior to the 181st day after the date of original issuance of the old notes and use our best efforts to cause the shelf registration statement to be declared effective within 60 days after such filing. We will be required to use our best efforts to keep such shelf registration statement continuously effective, supplemented and amended until the second anniversary of the date of original issuance of the old notes or such shorter period that will terminate when all the transfer restricted notes covered by the shelf registration statement have been sold pursuant thereto. We will, in the event that a shelf registration statement is filed with respect to the old notes, provide each holder with copies of the prospectus that is a part of the shelf registration statement, notify each such holder when the shelf registration statement for the old notes has become effective and take certain other actions as are required to permit unrestricted resales of the old notes. A holder that sells pursuant to the shelf registration statement will be required to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to certain of the civil liability provisions under the Securities Act in connection with such sales and will be bound by the provisions of the registration rights agreement that are applicable to such a holder (including certain indemnification rights and obligations). If (i) we fail to file any of the registration statements required by the registration rights agreement on or before the date specified for such filing, (ii) any of such registration statements is not declared effective by the SEC or prior to the date specified for such effectiveness, (iii) we fail to consummate the exchange offer within 60 days of the date specified for effectiveness with respect to the exchange offer registration statement, or (iv) the shelf registration statement with respect to the old notes or the exchange offer registration statement is declared effective but thereafter, subject to certain exceptions, ceases to be effective or usable in connection with the exchange offer or resales of transfer restricted notes, as the case may be, during the periods specified in the registration rights agreement, then the interest rate on transfer restricted notes will increase, with respect to the first 90-day period immediately following the occurrence of any default referred to in clauses (i) through (iv) above by 0.50% per annum and will increase by an additional 0.50% per annum with respect to each subsequent 90-day period until all such defaults have been cured, up to a maximum amount of 2% per annum with respect to all such defaults. Following the cure of all such defaults, the accrual of all such additional interest will cease and the interest rate will revert to the original rate. MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS The following is a general discussion of the material U.S. federal income tax considerations to holders of the old notes and new notes. This discussion is based upon the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations, Internal Revenue Service ("IRS") rulings, and judicial decisions now in effect, all of which are subject to change (possibly with retroactive effect) or different interpretations. This discussion does not purport to deal with all aspects of federal income taxation that may be relevant to a particular investor's decision to purchase or exchange notes, and it is not intended to be wholly applicable to all categories of investors, some of which, such as dealers in securities, banks, insurance companies, tax-exempt organizations, regulated investment companies, persons holding notes as a hedge against currency risks or as a position in a straddle for tax purposes, or persons whose functional currency is not the United States dollar, may be subject to special rules. In addition, this discussion is limited to persons that will hold the notes as a capital asset (generally, property held for investment). Further, the old notes were sold only to United States persons that are qualified institutional buyers and, therefore, the comments are addressed primarily to such persons as holders. Finally, this summary does not describe any tax considerations arising under the U.S. estate tax, the U.S. alternative minimum tax, or the laws of any applicable foreign, state, or local jurisdiction. 121 YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES OF THE EXCHANGE OF OLD NOTES FOR NEW NOTES AND THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE APPLICABILITY OF ANY FEDERAL TAX LAW OR ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND ANY CHANGES (OR PROPOSED CHANGES) IN APPLICABLE TAX LAWS OR INTERPRETATIONS THEREOF. NOTES Stated Interest and Original Issue Discount. The notes were issued with, and the new notes will be deemed to have, original issue discount ("OID") for U.S. federal income tax purposes. OID is the excess of the stated redemption price at maturity of a note over its issue price. The stated redemption price at maturity of a note is the sum of all payments provided by the instrument, whether denominated as interest or principal, required to be made on the note other than payments of qualified stated interest. Qualified stated interest is interest that is unconditionally payable at least annually at a single fixed rate of interest. Interest is payable on the notes on June 1 and December 1 of each year, beginning December 1, 2001, at a rate of 12.5%. The stated interest payments on the notes will constitute qualified stated interest and will not be included in a note's stated redemption price at maturity. You will be required to include stated interest in your income at the time it accrues or is received, depending on whether you use the cash or accrual method of accounting. Each note will be treated by the IRS as having been issued as part of an investment unit consisting of the note and the associated class A common stock. The issue price of a unit is the first price at which a substantial amount of the units was sold to the public, ignoring sales to underwriters or placement agents. We allocated the issue price of a unit between the note and the associated class A common stock on the basis of their relative fair market values. The units were sold to the public for $945. Each unit was comprised of a note having an issue price of $888.00 and a share of class A common stock with an ascribed value of $57.00. You may make a different allocation, provided that you explicitly disclose to the IRS that your allocation is different from the one made by us. Disclosure must be made on a form prescribed by the IRS and must be attached to your timely filed federal income tax return for the taxable year that includes the acquisition date of the unit. In all other instances, the allocation to be made by us will be binding on us and all holders. The allocation is not binding on the IRS, however, and it is possible that the IRS will assert that a different allocation is appropriate. If such an assertion were made successfully, the amount of OID associated with the notes would be increased or decreased accordingly. All notes that you acquire will be treated as a single debt instrument for purposes of applying the OID rules. You will be required to include OID in gross income as ordinary income as it accrues under a constant yield method before you receive cash payments attributable to such income, regardless of your regular method of accounting. The amount of OID includable in your income will equal the sum of the daily portions of OID for each day during the taxable year when you held a note. The daily portion is determined by allocating the OID for an accrual period equally to each day in that accrual period. The accrual period for a note may be of any length up to one year, so long as each scheduled payment of principal or interest occurs either on the first or final day of an accrual period, and may vary in length over the term of a note. The amount of OID for an accrual period is generally equal to the product of the note's adjusted issue price at the beginning of such accrual period and its yield to maturity, determined on the basis of a compounding assumption that reflects the length of the accrual period, less the amount of any qualified stated interest allocable to the accrual period. The adjusted issue price of a note at the beginning of any accrual period equals the issue price of the note increased by the amount of all previously accrued OID and reduced by the amount of all prior cash payments on the note, other than qualified stated interest payments. The yield to maturity of a 122 note is the interest rate that, when used in computing the present value of all payments to be made on a note, produces an amount equal to the issue price of the note. Under these rules, you generally will have to include in income increasingly greater amounts of OID in successive accrual periods. Acquisition Premium. If you purchase a note for an amount greater than its adjusted issue price as of the purchase date but less than or equal to its stated redemption price at maturity, you will have purchased the note at an "acquisition premium." You will reduce the amount of OID that you must include in your gross income for a taxable year by the amount of acquisition premium properly allocable to that year. Bond Premium. If you purchase a note for an amount greater than its stated redemption price at maturity, the note has "bond premium." You may elect to amortize bond premium over the remaining term of the note or, if it results in a smaller amount of amortizable bond premium, until an earlier call date. If you elect to amortize bond premium, you will reduce the amount of interest that you must include in income. The reduction will equal the portion of premium allocable to the period ending on an interest payment date or at the stated maturity, as the case may be, as computed based on the note's yield to maturity. If an election to amortize bond premium is not made, you must include the full amount of each interest payment in income in accordance with your regular method of accounting. In that case, you will receive a tax benefit from the premium only in computing your gain or loss on the sale or other disposition or payment of the principal amount of a note. If you elect to amortize bond premium, that election will apply to all notes and other debt instruments that you hold during the first taxable year to which the election applies or that you subsequently acquire. You may revoke the election only with the consent of the IRS. Market Discount. If you purchase a note, other than at original issue, for an amount that is less than its revised issue price, the amount of the difference will be "market discount," unless the difference is de minimis. You will be required to treat any gain realized on a partial principal payment or on the sale or other disposition of a note purchased with market discount as ordinary income, not capital gain, to the extent of the accrued market discount that you have not previously included in income. In addition, you may be required to defer, until the maturity date of the note or its earlier disposition in a taxable transaction, the deduction of a portion of the interest expense on any debt incurred or continued to purchase or carry the note. Any market discount will accrue on a straight line basis from the date when acquired to the maturity date, unless you elect to accrue market discount on a constant interest method. You may elect to include market discount in income currently as it accrues under either the straight line or constant interest method. If you make this election, it will apply to all market discount obligations acquired during or after the first taxable year to which the election applies. You may revoke this election only with IRS consent. If you make the election, you would not be required to defer interest deductions on debt incurred or maintained to purchase or carry the note. Election to Treat All Interest as OID. You may elect, subject to certain limitations, to include all interest that accrues on a note in gross income on a constant yield basis. For purposes of this election, interest includes stated interest, OID, market discount, de minimis market discount and unstated interest, as adjusted by any amortizable bond premium or acquisition premium. If you make this election, the issue price of a note will equal your basis in the note immediately after you acquire it. The issue date of a note will be the date when you acquire the note. This election generally will apply only to the note for which it is made. The election may be revoked only with IRS consent. 123 If you make this election for a note on which there is market discount, you will be treated as having made the election to include market discount in income currently over the life of all debt instruments you hold or subsequently acquire. See "Market Discount." Sale, Exchange, and Retirement of Notes. You generally will recognize gain or loss upon the sale, exchange, repurchase, redemption, retirement or other disposition of a note measured by the difference (if any) between the amount of cash and the fair market value of any property you receive and your adjusted tax basis in that note. To the extent that the cash or other property is attributable to the payment of accrued interest not previously included in income, that amount will be taxable as ordinary income. Your adjusted tax basis in a note will equal the cost of the note to you (not including the portion of the purchase price that is allocated to the class A common stock) plus any amounts included in income as OID and less any payments received by you, other than stated interest, and any premium amortized by you. Any gain or loss recognized on the sale, exchange, repurchase, redemption, retirement or other disposition of a note should be capital gain or loss, except to the extent of market discount, and will be long-term capital gain or loss if the note has been held by you for more than one year. If you are a noncorporate holder, any long-term capital gain you recognize may be taxable at reduced rates. Your ability to deduct capital losses may be limited. THE EXCHANGE OFFER The exchange of old notes for new notes under the exchange offer should not constitute a significant modification of the terms of the notes and should have no U.S. federal income tax consequences to you. You will continue to be required to include qualified stated interest payments and OID in your gross income on the notes received in the exchange in the same manner as when you held the notes given up in the exchange. If there is a default in connection with the exchange offer, liquidated damages will be paid to you through an increased interest rate on the notes. Because there is only a remote possibility that the liquidated damages will become payable, we believe that the liquidated damages will not be treated as OID. Instead, any liquidated damages should be taken into account by you as ordinary income only to the extent and at such time that such amounts become fixed or are actually paid, in accordance with your method of accounting for U.S. federal income tax purposes. INFORMATION REPORTING AND BACKUP WITHHOLDING We are required to provide the IRS and holders of record other than corporations and other exempt holders with information returns each year stating the amount of OID that accrued on the notes during the calendar year. In general, information reporting requirements may apply to principal and interest payments on a note and to payments of the proceeds of a sale of a note. In addition, a backup withholding tax may apply to such payments at the applicable rate, which is 31% now and will be 30.5% for payments made after August 6, 2001. The backup withholding tax may apply unless you (i) are a corporation or come within certain other exempt categories and, when required, demonstrate your exemption, or (ii) provide a correct taxpayer identification number, certify as to no loss of exemption from backup withholding, and otherwise comply with applicable requirements of the backup withholding rules. If you do not provide us with your correct taxpayer identification number, you may be subject to penalties imposed by the IRS. Any amounts withheld under the backup withholding rules will be allowed as a credit against your U.S. federal income tax liability if the required information is furnished to the IRS. 124 LEGAL MATTERS The validity of the new notes offered pursuant to this prospectus will be passed upon for us by Thompson & Knight LLP, Houston, Texas. CHANGE IN ACCOUNTANTS On March 14, 2001, we terminated Hidalgo, Banfill, Zlotnik & Kermali, P.C. ("Hidalgo") as our independent auditors and engaged BDO Seidman, LLP ("BDO") as our new auditors. Prior to such engagement, we had not consulted with BDO on issues relating to our accounting principles or the type of audit opinion to be issued with respect to our financial statements. Hidalgo's reports for the years ended December 31, 1998 and 1999 contained a "going concern" qualification due to our default under our bank loan resulting from the commodity price decreases experienced during the latter half of 1998 and our subsequent bankruptcy. Hidalgo's reports for such periods did not contain any adverse opinion or disclaimer of opinion, nor were they qualified (other than as described above), or modified as to uncertainty, audit scope or accounting principles. There was no disagreement between us and Hidalgo during any period of their engagement through the date of their dismissal on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures which, if not resolved to the satisfaction of Hidalgo, would have caused them to make reference to the matter in their reports. EXPERTS The financial statements included in this prospectus and in the Registration Statement have been audited by BDO Seidman, LLP and by Hidalgo, Banfill, Zlotnik & Kermali, P.C., independent certified public accountants, to the extent and for the periods set forth in the respective reports of such firms contained herein and in the Registration Statement. All such financial statements have been included in reliance upon such reports given upon the authority of such firms as experts in auditing and accounting. RESERVE ENGINEERS Information in this prospectus and in our attached financial statements relating to our estimated proved reserves of oil and natural gas and the related estimates of future net revenues and present values thereof as of December 31, 1998, 1999 and 2000, have been prepared by Huddleston & Co., Inc., independent petroleum engineers.

F-7 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE 1 -- BASIS OF PRESENTATION Basis of Presentation Tri-Union Development Corporation ("New TDC") (formerly Tribo Petroleum Corporation ("Tribo")) was incorporated in the state of Texas in September, 1992. New TDC and its subsidiaries ("the Company") is an independent oil and natural gas company engaged in the acquisition, operation and development of oil and natural gas properties primarily in areas of Texas and Louisiana, offshore in the shallow waters of the Gulf of Mexico, and in the Sacramento Basin of northern California. The consolidated financial statements include the accounts of New TDC and its wholly-owned subsidiary Tri-Union Development Corporation ("TDC"), which was incorporated in the state of Texas in November, 1967, and TDC's wholly-owned subsidiary Tri-Union Operating Company ("TOC"), which was incorporated in the state of Delaware in November, 1974. New TDC purchased TDC and its subsidiary TOC in 1996 in a purchase transaction with an unrelated entity. All significant intercompany accounts and transactions have been eliminated in consolidation. In July 2001, New TDC and TDC merged and the surviving corporation was New TDC. NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Interim Presentation The accompanying unaudited consolidated interim financial statements and disclosures for the six months ended June 30, 2000 and 2001, have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America and, in the opinion of management, reflect all adjustments (consisting solely of normal recurring adjustments) necessary for a fair presentation in all material respects of the results for the interim periods. The interim unaudited financial statements for the six months ended June 30, 2000 and 2001 should be read in conjunction with the Company's annual consolidated financial statements for the years ended December 31, 1999 and 2000. The results of operations for the six months ended June 30, 2001 are not necessarily indicative of results to be expected for the full year. Use of Estimates The accompanying financial statements are prepared in conformity with accounting principles generally accepted in the United States of America which require management to make estimates and assumptions that effect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant assumptions are required in the valuation of proved oil and natural gas reserves, which as described herein may affect the amount at which oil and natural gas properties are recorded. Actual results could differ from these estimates. Restricted Cash and Bonds The Company had restricted cash balances at December 31, 1999 and 2000 of $340,957 and $372,697, respectively. These restricted cash balances are pledged for regulatory operating deposits and performance bonds. In addition, the Company has zero coupon U.S. Treasury Bonds with a 2019 maturity value of $12,250,000, held in trust and pledged to the Minerals Management Service ("MMS") for the plugging and abandonment of certain wells and the decommissioning of offshore platforms. At F-8 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) December 31, 1999 and 2000, these bonds had a carrying value of $3,840,550 and $4,301,948, respectively. Marketable Securities The Company's marketable securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities. Trading securities are recorded at fair value on the balance sheet as current assets, with the change in fair value during the period included in earnings. Marketable securities that the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity securities and recorded at amortized cost. Marketable securities not classified as either held-to-maturity or trading securities are classified as available-for-sale securities. Available-for-sale securities are recorded at fair value in the accompanying balance sheet, with the change in fair value during the period excluded from earnings and recorded net of tax as a component of other comprehensive income. Oil and Natural Gas Interests The Company follows the full cost method of accounting for oil and natural gas property acquisition, exploration and development activities. Under this method, all productive and nonproductive costs incurred in connection with the acquisition of, exploration for and development of oil and natural gas reserves for each cost center are capitalized. Capitalized costs include lease acquisitions, geological and geophysical work, delay rentals and the costs of drilling, completing and equipping oil and natural gas wells. Gains or losses are recognized only upon sales or dispositions of significant amounts of oil and natural gas reserves. Proceeds from all other sales or dispositions are treated as reductions to capitalized costs. Internal costs, including salaries, benefits and other internal salary related costs, which can be directly identified with acquisition, exploration or development activities are capitalized while any costs related to production, general corporate overhead, or similar activities are charged to expense. Geological and geophysical costs not directly associated with a specific unevaluated property are included in the amortization base as incurred. Capitalized internal costs directly identified with the Company's acquisition, exploration and development activities amounted to approximately $680,000, $764,000 and $767,000 in 1998, 1999 and 2000, respectively. Internal costs included in capitalized oil and gas properties amounted to approximately $1,444,000 and $2,211,000 at December 31, 1999 and 2000, respectively. The capitalized costs of oil and natural gas properties, plus estimated future development costs relating to proved reserves and estimated costs of plugging and abandonment, net of estimated salvage value, are amortized on the unit-of-production method based on total proved reserves. The computation of depreciation, depletion and amortization ("DD&A") takes into consideration restoration, dismantlement and abandonment costs and the anticipated proceeds from equipment salvage. The estimated restoration, dismantlement and abandonment costs for onshore properties are expected to be offset by the estimated salvage value of lease and well equipment. The Company has recorded an offshore abandonment liability of $2,675,000 as of December 31, 2000 based in total expected abandonment costs of $14,627,000. This liability is included in accumulated DD&A on the consolidated balance sheets. For the years ended December 31, 1998, 1999, and 2000, the Company recorded accretion of its offshore abandonment liability of $687,000, $905,000, and $1,083,000, respectively. This accretion is recorded as a component of DD&A expense in the consolidated statements of operations. (See Note 12). F-9 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) The costs of unproved properties are excluded from amortization until the properties are evaluated, subject to an annual assessment of whether impairment has occurred. In determining whether impairment of unevaluated properties has occurred, management evaluates, among other factors, current oil and natural gas industry conditions, capital availability, primary lease terms of the properties, holding periods of the properties, and available geological and geophysical data. Any impairment assessed is added to the costs being amortized. Costs of drilling exploratory dry holes are included in the amortization base immediately upon determination that a well is dry. At December 31, 2000, all of the Company's oil and gas properties were classified as evaluated and are included in the amortization base. The Company's proved oil and natural gas reserves were estimated by an independent petroleum engineering firm. The capitalized oil and natural gas property costs, less accumulated depreciation, depletion and amortization and related deferred income taxes, if any, are generally limited to an amount (the ceiling limitation) equal to the sum of (a) the present value of estimated future net revenues computed by applying current prices in effect as of the balance sheet date (with consideration of price changes only to the extent provided by contractual arrangements) to estimated future production of proved oil and natural gas reserves, less estimated future expenditures (based on current costs) to be incurred in developing and producing the reserves using a discount factor of 10% and assuming continuation of existing economic conditions; and (b) the cost of investments in unevaluated properties excluded from the costs being amortized. No ceiling writedown was recorded in 1998, 1999 or 2000. General and administrative expenses are reported net of amounts allocated to working interest owners of the oil and natural gas properties operated by Tribo, net of amounts charged for administrative and overhead costs and net of amounts capitalized pursuant to the full cost method of accounting. Furniture, Fixtures and Equipment Furniture, fixtures and equipment are carried at cost. Depreciation is provided on the straight-line basis using estimated useful lives of five to ten years. At the time of a retirement or sale, the related cost and accumulated depreciation are removed from the accounts, and any resulting gain or loss is recorded to income. Maintenance and repairs are charged to expense as incurred. Renewals, betterments and expenditures which increase the value of the property or extend its useful life, are capitalized. Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Financial Instruments and Concentration of Credit Risk Financial instruments that subject the Company to credit risk consist of accounts receivable. The receivables are primarily from companies in the oil and natural gas industry or from individual oil and F-10 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) natural gas investors. During 1998, 1999 and 2000, the Company had revenues from certain customers exceeding 10% of total revenues as follows: <Table> <Caption> 1998 1999 2000 ---- ---- ---- Customer A......................................... 13% 35% 31% Customer B......................................... 12% 18% 16% Customer C......................................... 22% 11% -- Customer D......................................... -- -- 11% </Table> In the case of receivables from joint interest owners, the Company may have the ability to offset amounts due against the participant's share of production from the related property. The estimated fair value of financial instruments has been determined by the Company using available market information and appropriate valuation methodologies. The fair value of these instruments approximates their carrying value at December 31, 1999 and 2000. Income Taxes The Company accounts for income taxes using the "liability method." Accordingly, deferred tax liabilities or assets are determined based on temporary differences between the financial statement and income tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Environmental Matters Environmental costs are expensed or capitalized depending on their future economic benefit. Costs that relate to an existing condition caused by past operations and have no future economic benefit are expensed. Liabilities for future expenditures of a noncapital nature are recorded when future environmental expenditures and/or remediation is deemed probable, and the costs can be reasonably estimated. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. Derivative Transactions The Company sometimes enters into fixed-price physical delivery contracts and commodity price swap derivatives to manage price risk with regard to a portion of its natural gas and crude oil production. The Company recognizes revenues under fixed-price physical delivery contracts as the gas is sold. Prior to January 1, 2001, the Company followed the guidance in Statement of Financial Accounting Standards No. 80 ("SFAS No. 80"), "Accounting for Futures Contracts", in accounting for its commodity price swap derivative contracts. Under SFAS No. 80, commodity price swap derivative contracts were accounted for using the hedge method of accounting. Under this method, realized gains and losses on qualifying hedges were recognized in oil and gas revenues when the associated production occurred and the resulting cash flows were reported as cash flows from operations. These swap contracts were designated as hedges and changes in their fair value correlated with changes in the price of anticipated future production such that the Company's exposure to the effects of commodity price changes was reduced. If a contract does not qualify as a hedge, any changes in its fair value are recorded currently. Statement of Financial Accounting Standards No. 133 ("SFAS No. 133"), "Accounting for Derivative Instruments and Hedging Activities", as amended by SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities -- Deferral of the Effective Date of FASB No. 133", F-11 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) and SFAS No. 138, "Accounting for Certain Derivative Instruments and Certain Hedging Activities" was effective for the Company as of January 1, 2001. SFAS No. 133 requires that an entity recognize all derivatives as either assets or liabilities measured at fair value. The accounting for changes in the fair value of a derivative depends on the use of the derivative. Derivatives that are not hedges must be adjusted to fair value through income. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives will either be offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. The adoption of these new accounting standards had no impact on the Company's financial statements because the Company had no derivatives at January 1, 2001. Earnings (Loss) Per Share Basic earnings per share includes no dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution of securities that could share in the earnings of an entity. The Company had no potentially dilutive securities for the years ended December 31, 1998, 1999 or 2000. Comprehensive Income The Company has elected to report comprehensive income in a consolidated statement of comprehensive income. Comprehensive income is comprised of net income and all changes to stockholders' equity, except those due to investments by stockholders, changes in paid-in capital and distributions to stockholders, and is presented net of income taxes. Reclassifications Certain reclassifications have been made to the 1998 and 1999 balances to conform to the 2000 presentation. Recently Issued Accounting Pronouncements In December 1999, the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements." SAB 101 outlines the basic criteria that must be met to recognize revenue, and provides guidance for disclosure related to revenue recognition policies. In June 2000, the SEC issued SAB 101B, that delayed the implementation date of SAB 101 until the quarter ended December 31, 2000, with retroactive application to the beginning of the Company's fiscal year. The adoption of SAB 101 did not have a material impact on the Company's financial position or results of operations. In March 2000, the FASB issued Interpretation No. 44, "Accounting for Certain Transactions Involving Stock Compensation -- An Interpretation of APB No. 25 ("FIN 44"). FIN 44 clarified the application of Opinion No. 25 for certain issues, including: a) the definition of employee for purposes of applying Opinion No. 25; b) the criteria for determining whether a plan qualifies as a non-compensatory plan; c) the accounting consequences of various modifications to the terms of a previously fixed stock option or award; and d) the accounting for an exchange of stock compensation awards in a business combination. In general, FIN 44 is effective July 1, 2000. The adoption of FIN 44 did not have a material impact on the Company's financial position or results of operations. F-12 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) In June 2001, the Financial Accounting Standards Board finalized FASB Statements No. 141, Business Combinations ("SFAS 141"), and Statement No. 142, Goodwill and Other Intangible Assets ("SFAS 142"). SFAS 141 requires the use of the purchase method of accounting and prohibits the use of the pooling-of-interests method of accounting for business combinations initiated after June 30, 2001. SFAS 141 also requires that the Company recognize acquired intangible assets apart from goodwill if the acquired intangible assets meet certain criteria. SFAS 141 applies to all business combinations initiated after June 30, 2001 and for purchase business combinations completed on or after July 1, 2001. It also requires, upon adoption of SFAS 142, that the Company reclassify the carrying amounts of intangible assets and goodwill based on the criteria in SFAS 141. SFAS 142 requires, among other things, that companies no longer amortize goodwill, but instead test goodwill for impairment at least annually. In addition, SFAS 142 requires that the Company identify reporting units for the purposes of assessing potential future impairments of goodwill, reassess the amortization of intangible assets with an indefinite useful life. An intangible asset with an indefinite useful life should be tested for impairment in accordance with SFAS 142. SFAS 142 is required to be applied in fiscal years beginning after December 15, 2001 to all goodwill and other intangible assets recognized at that date, regardless of when those assets were initially recognized. SFAS 142 requires the Company to complete a transitional goodwill impairment test six months from the date of adoption. The Company is also required to reassess the useful lives of other intangible assets within the first interim quarter after adoption of SFAS 142. Currently, the Company is assessing but has not yet determined how the adoption of SFAS 141 and SFAS 142 will impact its financial position and results of operations. NOTE 3 -- BANKRUPTCY In October, 1997, the Company obtained a short-term bank loan of $105 million (the "Acquisition Facility") to finance the purchase of certain oil and gas properties. During 1997 and through May 1998, the Company drew approximately $35 million and $69 million, respectively, against the Acquisition Facility. In August, 1998 before the Company was able to refinance the Acquisition Facility with term debt, commodity prices began falling, with oil prices ultimately reaching a twelve-year low in December of that year. The resultant negative effect on the Company's cash flow from the deterioration of commodity prices, coupled with the required amortization payments on the Acquisition Facility, severely restricted the amount of capital the Company was able to dedicate to development drilling. Consequently, the Company's oil and natural gas production declined which further exacerbated its liquidity problem. During February 2000, due to the Company's default under the terms of the Acquisition Facility, the bank demanded payment of all principle and interest. On March 14, 2000, TDC (the "Debtor") sought protection under Chapter 11 of the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the Southern District of Texas, Houston Division ("Bankruptcy Court"). Under Chapter 11, certain claims against the Debtor in existence prior to the filing of the petition are stayed while the Debtor continues business operations as debtor-in-possession. These claims are reflected in the December 31, 2000 balance sheet as "liabilities subject to compromise." Additional claims (liabilities subject to compromise) may arise subsequent to the bankruptcy filing date resulting from rejection of executory contracts by the Bankruptcy Court (or agreed to by parties in interest). Claims secured against the Debtor's assets are also stayed, although the holders of such claims have the right to move the court for relief from the stay. All payments made from TDC to TOC, TPC or any related party are required to be approved by the Bankruptcy Court. F-13 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Reorganization Costs -- As a result of TDC filing for protection under Chapter 11 of the U.S. Bankruptcy Code, the Company incurred certain reorganization costs totaling $21,487,191 during the year ended December 2000 which include the following: Amended Rejection of fixed-price physical delivery contract -- The bankruptcy court approved a motion to reject a fixed-price physical delivery contract. A claim has been filed by the damaged party resulting in a liability of $17,059,272 (see Note 9). Professional fees and other -- The Company was required to hire certain legal and accounting professionals to help the Company in its bankruptcy proceedings. The Company has estimated these fees to be $3,611,760 through December 31, 2000. During the year ended December 31, 2000, the Company paid $1,692,007 of these professional fees. Retention costs -- In an effort to maintain certain key employees through the bankruptcy period, the Company is seeking approval from the creditors committee and the bankruptcy court to set aside approximately $855,000 to pay employees when certain conditions are met. Interest -- The Company earned interest income of $538,841 from March 14, 2000 through December 31, 2000. These reorganization costs were accrued on the accompanying consolidated balance sheet as of December 31, 2000, as follows: <Table> <Caption> PRE-PETITION ACCOUNTS LIABILITIES PAYABLE SUBJECT TO AND ACCRUED COMPROMISE EXPENSES ------------ ----------- Cancellation of fixed-price physical delivery contract.... $17,059,272 $ -- Professional fees and other............................... 860,000 1,059,753 Retention................................................. -- 855,000 </Table> The plan of reorganization also required the Company to pay additional bank charges and interest of $7.7 million of which $4.0 million was accrued for the three months ended March 31, 2001, and $3.7 million was accrued for the period from April 1, 2001 to June 18, 2001, and additional professional fees of $4.0 million. The additional professional fees were reduced by $3.3 million upon completion of the proposed offering as a condition of the settlement of the Company's counterclaim against the bank. These costs were expensed in June 2001 when the Company emerged from bankruptcy. During the six month period ended June 30, 2001, the Company incurred additional reorganization costs totalling $7,311,108, which comprised: <Table> <Caption> AMOUNT ---------- Professional fees........................................... $3,727,279 Interest.................................................... 1,700,839 Forgiveness of indebtedness with and transfers of oil and gas properties to related parties (see Note 14(d))........ 1,882,990 ---------- Total............................................. $7,311,108 ========== </Table> F-14 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) NOTE 4 -- ALLOWANCE FOR DOUBTFUL ACCOUNTS The activity of the allowance for doubtful accounts for the year ended December 31, was as follows: <Table> <Caption> 1998 1999 2000 --------- -------- --------- Balance, beginning of year....................... $ 310,071 $695,791 $ 867,864 Additions (Recoveries)......................... 629,612 225,739 (498,436) Write offs.....................................

The Company held no available-for-sale securities during 2000. Proceeds, realized gains, and realized losses from the sales of securities classified as available-for-sale for the year ended December 31, 1998 were $319,217, $35,736, and $63,150, respectively. For the year ended December 31, 1999, the Company did not sell any available-for-sale securities. For the purposes of determining realized gains and losses, the cost of securities sold was based on specific identification. During 2000, the Company began to buy and sell marketable equity securities to take advantage of favorable market conditions. Accordingly, all available-for-sale securities were recategorized to trading securities. <Table> <Caption> 1999 2000 ------------------- ------------------- MARKET MARKET VALUE COST VALUE COST -------- -------- -------- -------- Classified as trading securities -- all common stock......................... $ -- $ -- $472,248 $308,850 </Table> During 2000, gross gains and gross losses included in results of operations that resulted from transfers of securities from the available-for-sale category into the trading category were $510,670 and $42,688, respectively.

The note payable balance at December 31, 1999 and 2000 of $104,700,000 and $104,323,500, respectively, resulted from a $105,000,000 acquisition facility with a bank dated October 15, 1997. The borrowings available under the acquisition facility were to be redetermined after December 31 and June 30 of each year based upon the Company's proven reserves of oil and natural gas. Interest accrued at prime plus 4%, payable at 90 day intervals. The acquisition facility was collateralized by deeds of trust, mortgages, assignments of oil and natural gas production, security agreements and financing statements on substantially all of the real and personal property of the Company. Additional collateral includes the assignment of the common stock of the Company and the personal guarantee of the Company's stockholder. In February 2000, due to the Company's violations of the terms of the acquisition facility, the bank demanded payment of the note and all accrued interest. On March 14, 2000 TDC filed for protection under Chapter 11 of the United States Bankruptcy Code (see Note 3). Beginning March 14, 2000, the Company accrued interest at 12% per annum, which is different from the stated rate of prime plus 4% (12.5% at December 31, 2000). Because of their adversarial relationship with the bank, the Company was unable to obtain sufficient information from the bank regarding the rates charged on the outstanding balance of the loan. The 12% rate accrued by the Company through December 31, 2000 was consistent with rates the Company had been charged by the bank prior to the bankruptcy. The actual rate charged by the bank from March 14, 2000 through the date of the Company's emergence from bankruptcy in June 2001 could not be determined by the Company; however, the final amount paid to the bank differed only $100,000 from the Company's estimate. NOTE 9 -- DERIVATIVE TRANSACTIONS The Company may use derivative instruments to manage exposures to commodity prices. The Company's objectives for holding derivatives are to minimize the risks using the most effective methods to eliminate or reduce the impacts of this exposure. In April 1999, the Company entered into a thirty-two month fixed-price physical delivery contract with Aquila Energy Marketing Corporation ("Aquila") that obligated the Company to deliver specified volumes of natural gas to Aquila at a certain price. For the years 1999, 2000, and 2001, the F-17 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Company agreed to deliver approximately 1,525,000 Mbtu, 3,098,000 Mbtu, and 2,894,000 Mbtu, respectively, with prices ranging from $2.353/Mcf to $2.697/Mcf. With the authorization of the bankruptcy court, the Company rejected this fixed-price physical delivery contract effective December 20, 2000. Aquila filed a claim against the Company for damages relating to the cancellation of the contract for $17,559,272. The claim has been accrued by the Company and is included in pre-petition "liabilities subject to compromise" in the accompanying consolidated balance sheet as of December 31, 2000. In June, 2001 the Company entered into three commodity swap derivative contracts as a condition of the issuance of the Notes described in Note 14(f). Under the terms of the Notes, the Company must use these contracts to mitigate the volatility of the commodity prices to ensure that the Company has sufficient cash flows to service the Notes. These commodity swap derivative contracts are designated as cash flow hedges. The contracts do not qualify for hedge accounting under FAS No. 133, therefore, the Company recorded these contracts at their estimated fair values, and included the changes in their fair value in the statement of operations. As of June 30, 2001 the Company had three outstanding commodity price swap agreements. The following table sets forth the volumes and hedge prices of the contracts: <Table> <Caption> CONTRACT 1 CONTRACT 2 CONTRACT 3 ------------------------ ------------------------ ------------------------ CRUDE OIL NATURAL GAS NATURAL GAS ------------------------ ------------------------ ------------------------ DATE VOLUME/DAY HEDGE PRICE VOLUME/DAY HEDGE PRICE VOLUME/DAY HEDGE PRICE ---- ---------- ----------- ---------- ----------- ---------- ----------- July 1 - December 31, 2001...................... 2.5 Mbbl $25.30/bbl 10.7 MMcf $3.96/mcf 7.3 MMcf $4.62/mcf January 1 - June 30, 2002... 2.2 Mbbl 25.30/bbl 6.7 MMcf 3.96/mcf 4.3 MMcf 4.62/mcf July 1 - December 31, 2002...................... 2.2 Mbbl 25.30/bbl 6.7 MMcf 3.96/mcf 4.3 MMcf 4.36/mcf January 1 - June 30, 2003... 1.9 Mbbl 25.30/bbl 7.7 MMcf 3.96/mcf 3.4 MMcf 4.36/mcf </Table> The contracts call for the Company to receive or make payments based upon the differential between the hedge prices and the market prices, as defined in the contracts, for the notional quantities. The estimated fair value of these contracts at June 30, 2001 of $3,586,626 is included in the accompanying balance sheet as a current asset of $1,649,326 and as a non-current asset of $1,937,300. The unrealized gain of $3,586,626 is included in the accompanying statement of operations as "Gain on Derivative Contracts". The Company is exposed to credit risk in the event of nonperformance by the counterparty in the commodity price swap contracts; however, the Company does not anticipate nonperformance by the counterparty. NOTE 10 -- ACQUISITION OF OIL AND NATURAL GAS PROPERTIES On March 31, 1998, the Company purchased certain oil and gas properties from Apache for approximately $63,000,000. The acquisition was accounted for using the purchase method of accounting, and accordingly, the purchase price was allocated to the oil and gas properties acquired based on estimated fair values at the date of acquisition. In this transaction, the Company acquired only oil and gas properties from Apache and assumed no liabilities. The operating results of the assets acquired have been included in the accompanying consolidated statement of loss and comprehensive loss beginning March 31, 1998. The unaudited pro forma information for the year ended December 31, 1998 shown below assumes that the acquisition occurred on January 1, 1998.

F-20 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Lawsuits The Company is the defendant in several lawsuits filed by companies for breach of contract with claims and joint interest disputes totaling approximately $9,285,000. The Company has accrued such amount which is included in pre-petition liabilities subject to compromise in the accompanying balance sheet as of December 31, 2000. The Company is a defendant in various lawsuits arising from normal business activities. Management has reviewed pending litigation with legal counsel and believes that these actions are without merit or that the ultimate liability, if any, resulting from them will not materially affect the Company's financial position. Regulatory and environmental contingencies During 2000, the Company reached a settlement with the MMS resolving a civil enforcement action related to non-environmental infractions of platform construction brought against the Company in August 2000 by the MMS. The Company agreed to pay civil penalties of $506,600 with $25,325 to be paid out initially, and the remaining $481,175 to be paid out in quarterly installments over a two-year period. The settlement between the MMS and the Company was not an admission of liability by the Company with respect to the violations alleged by the MMS. The Company, as an owner and operator of oil and natural gas properties, is subject to various federal, state and local laws and regulations relating to discharge of materials into, and protection of, the environment. These laws and regulations may, among other things, impose liability on the lessee under an oil and natural gas lease for the cost of pollution clean-up resulting from operations and subject the lessee to liability for pollution damages. The Company maintains insurance coverage, which it believes, is customary in the industry, although it is not fully insured against all environmental risks. The Company is not aware of any environmental claims existing as of December 31, 2000 which would have a material impact on its financial position or results of operations. There can be no assurance however, that current regulatory requirements will not change, or past non-compliance with environmental laws will not be discovered on the Company's properties. Other As of December 31, 2000, the Company expects the future cost of restoration, dismantlement and abandonment of certain offshore wells and the decommissioning of offshore platforms to be approximately $14,627,000. In connection therewith, the Company has provided zero coupon U.S. Treasury Bonds with a 2019 maturity value of $12,250,000 to be held in trust and pledged to the MMS for a portion of such estimated costs. At December 31, 1999 and 2000, these bonds had a carrying value of $3,840,550 and $4,301,948, respectively. NOTE 13 -- CAPITAL STOCK Effective June 15, 2001, the Company was authorized to issue two classes of common stock, class A and class B. The holders of the common stock are entitled to one vote for each share on all matters voted upon by shareholders, including the election of directors. Such holders are not entitled to vote cumulatively for the election of directors. Holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election, subject to the rights of holders of class B common stock described below. F-21 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Holders of class A and class B common stock are together entitled to participate pro rata in such dividends as may be declared in the discretion of the board of directors out of funds legally available therefore. Holders of class A and class B common stock together are entitled to share ratably in the net assets of the Company upon liquidation after payment or provision for all liabilities and any preferential rights. Holders of common stock have no preemptive rights to purchase shares of stock of the Company. Shares of common stock are not subject to any redemption provisions and are not convertible into any other securities of the Company, except that each share of class B common stock is convertible into one share of class A common stock under certain circumstances. Special Rights of Class B Common Stock In addition to the rights of the holders of common stock set forth above, the holders of a majority of the class B common stock, voting together as a single class, are entitled to designate one person to serve as a non-voting advisory observer to the Company's board of directors, and further, at any time, to cause the Company to increase the size of its board of directors and to immediately elect to the board of directors a number of directors (having full voting power) nominated by a majority of the holders of the class B common stock sufficient to constitute a majority of the board of directors. Until there are no outstanding shares of class B common stock, the board of directors may not consist of more than seven directors other than those nominated by the holders of the class B common stock in accordance with the foregoing. Only the holders of the class B common stock may remove the directors that such holders are entitled to designate. In addition to any vote required by law, all matters submitted to a vote of the Company's shareholders will require the approval of the holders of a majority of the issued and outstanding shares of class B common stock, voting separately as a single class. In addition, any amendment to the Company's Bylaws will require the approval of the holders of the majority of the issued and outstanding shares of class B common stock. NOTE 14 -- SUBSEQUENT EVENTS (a) During March, 2001, the Company entered into a lease agreement with a related party, which is owned and controlled by the Company's chief executive officer, for the lease of its current office facilities. The lease is on a month to month basis and requires the Company to pay the related party $26,000 per month. (b) On June 5, 2001, the Company sold certain oil and natural gas property for $2.2 million. (c) On May 23, 2001, TDC's plan of reorganization was confirmed by the bankruptcy court, pending the completion of the proposed securities offering. In accordance with this plan, the Company paid all pre-petition liabilities in full. In addition, the Company paid interest at 6% per annum for all unsecured pre-petition liabilities subject to compromise, and interest at prime plus 2% (11.5% at December 31, 2000) on the liability relating to the cancellation of a fixed-price physical delivery contract. In finalizing the plan, TDC's largest creditor agreed to a $3,300,000 reduction in its professional fees related to TDC's bankruptcy filing and a transfer of certain oil and gas properties to the Company's the sole shareholder and chief executive officer (see 14(d) below), in return for settlement of a lawsuit filed against the creditor by Tribo, TDC, and Tribo's then sole shareholder and chief executive officer. The $3,300,000 reduction in the creditor's professional fees was accounted for as a decrease in the Company's reorganization costs. (d) As a condition of TDC's plan of reorganization, on May 25, 2001, the Company agreed to transfer all of the oil and natural gas properties in Texas that were owned by Tribo Petroleum Corporation with a net book value at December 31, 2000 of approximately $1,098,000 to its affiliate, F-22 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Atasca Resources, Inc., a company owned by the Company's then sole shareholder and chief executive officer, at their net book value. Revenues from these properties totaled $1,142,932, $895,644, $1,777,649, $879,943, and $527,047 for the years ended December 31, 1998, 1999 and 2000, and the six months ended June 30, 2000 and 2001, respectively. In connection with this transaction, all balances owing to and from the Company by its affiliates on May 25, 2001 were forgiven. These balances aggregated to a net receivable from the affiliates of $1,883,000. As a consequence of these transactions, the Company recorded a one-time reorganization expense of approximately $1,883,000 in the second quarter of 2001. (e) On June 13, 2001, the Company increased its authorized share capital to 445,000 shares of class A common stock and 65,000 shares of class B common stock. The Company also effected a 238.333:1 stock split of its class A common stock. The consolidated financial statements give retroactive effect to the stock split for all periods presented. In connection with the stock split, the par value of the class A common stock decreased from $1.00 to $0.01 per share. The par value of the class B common stock is $0.01. The class B common stock is convertible into class A common stock upon the occurrence of certain events, as defined. (f) On June 18, 2001, the Company completed a unit offering of (1) $130 Million of 12.5% senior secured notes due 2006 ("Notes") and (2) 130,000 shares of class A common stock of Tribo. Each unit consisted of a Note in the principal amount of $1,000 and one share of class A common stock. The Notes are guaranteed by TDC. Notes The Notes mature on June 1, 2006 and require amortization payments of the greater of $20 million and 15.3% as of June 1, 2002 and 2003 and an amortization payment of the greater of $15 million and 11.5% as of June 1, 2004. Interest is payable semi-annually on June 1 and December 1 of each year. The Notes were issued at a 5.5% discount from their face amount resulting in an aggregate discount of $7,150,000 that is being amortized as additional interest expense over the term of the Notes. The 5.5% discount, together with value of the class A common stock issued in the offering which was also accounted for as bond discount, the allocated value of the class B common stock, and other offering costs aggregating a total of $44,241,000 (see below), make the effective interest rate on the Notes 21.7%. At any time prior to June 1, 2003, New TDC may redeem in the aggregate up to 30% of the then outstanding aggregate principal amount of the Notes with the Net Cash Proceeds of one or more equity offerings at a redemption price of 112.5% of the Notes, together with accrued and unpaid interest to the redemption date. Class A Common Stock The Company issued 130,000 shares of class A common stock with an estimated fair value of $17.6 million. This amount was allocated to the value of the class A common stock from the total proceeds received by the Company in the unit offering, thereby creating an additional bond discount which is being amortized to interest expense over the life of the bonds using the effective interest method. F-23 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Class B Common Stock In conjunction with the offering, the Company issued 65,000 shares of class B common stock to the initial purchaser of the Notes. These shares had a fair value of $11,000,000 and this value was considered to be offering costs of the Company's unit offering. Accordingly, $9,427,000 was allocated to the debt component of the unit offering, and $1,573,000 was allocated to the equity component of the unit offering. The portion of the offering costs associated with the issuance of the Notes is being amortized as additional interest expense over the term of the Notes. The class B common stock has special voting rights and the ability to control the board of directors of New TDC, subject to certain limitations (See Note 13). In addition, the Company incurred other offering costs of $11,709,000. Of these costs $10,064,000 was allocated to the debt component of the unit offering, and $1,645,000 was allocated to the equity component of the unit offering. The portion of the offering costs associated with the issuance of the Notes is being amortized as additional interest expense over the term of the Notes. Effective with the issuance of the class A and class B common stock, the Company's chief executive officer is no longer the sole shareholder as his shareholdings were effectively reduced to 55%. (g) On June 18, 2001, the Company entered into an agreement to hedge approximately 80% of the Company's projected oil and gas production from proved developed producing reserves through June 30, 2003 (See Note 9). (h) On July 27, 2001, New TDC merged with TDC, one of its wholly-owned subsidiaries. As a result of the merger, the surviving corporation was New TDC. NOTE 15 -- SUPPLEMENTAL OIL AND NATURAL GAS INFORMATION Information with respect to the Company's oil and natural gas producing activities is presented in the following tables. Estimates of reserve quantities, as well as future production and discounted cash flows before income taxes, were determined by an independent petroleum engineering firm, as of December 31, 1998, 1999 and 2000.

No income taxes are reflected above due to the Company's tax loss carryforwards. Oil and Natural Gas Reserves (Unaudited) The following table sets forth the Company's net proved oil and natural gas reserves at December 31, 1998, 1999 and 2000 and the changes in net proved oil and natural gas reserves for the years then ended. Proved reserves represent the estimated quantities of crude oil and natural gas which geological and engineering data demonstrate with reasonable certainty to be recoverable in the future years from known reservoirs under existing economic and operating conditions. The reserve information indicated below requires substantial judgment on the part of the reserve engineers, resulting in estimates which are not subject to precise determination. Accordingly, it is expected that the estimates of reserves will change as future production and development information becomes available and that revisions in these estimates could be significant. Reserves F-25 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) are measured in barrels (Bbls) in the case of oil, and units of one thousand cubic feet (Mcf) in the case of natural gas. <Table> <Caption> OIL (BBLS) GAS (MCF) ---------- --------- (AMOUNTS IN THOUSANDS) Proved reserves Balance, December 31, 1997................................ 1,521 79,583 Purchases of reserves in place......................... 9,816 28,542 Discoveries and extensions............................. 940 9,424 Revisions of previous estimates........................ 72 311 Production.............................................

The average prices used at December 31, 1998, 1999 and 2000, were $11.17, $25.57 and $25.90 per Bbl and $1.86, $2.96 and $10.31 per Mcf, respectively. No deduction has been made for depreciation, depletion or any indirect costs such as general corporate overhead or interest expense. Operating costs and production taxes are estimated based on current costs with respect to producing oil and natural gas properties. Future development costs are based on the best estimate of such costs assuming current economic and operating conditions. F-27 TRI-UNION DEVELOPMENT CORPORATION (FORMERLY TRIBO PETROLEUM CORPORATION) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Income tax expense is computed based on applying the appropriate statutory tax rate to the excess of future cash inflows less future production and development costs over the current tax basis of the properties involved, less applicable carryforwards, for both regular and alternative minimum tax. The future net revenue information assumes no escalation of costs or prices, except for oil and natural gas sales made under terms of contracts which include fixed and determinable escalation. Future costs and prices could significantly vary from current amounts and, accordingly, revisions in the future could be significant.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Tri-Union Development Corporation Article 2.02-1 of the Texas Business Corporation Act ("TBCA") provides that a corporation may indemnify any director or officer who was, is or is threatened to be made a named defendant or respondent in a proceeding because he is or was a director or officer, provided that the director or officer (i) conducted himself in good faith, (ii) reasonably believed (a) in the case of conduct in his official capacity, that his conduct was in the corporation's best interests, and/or (b) in other cases, that his conduct was at least not opposed to the corporation's best interests, and (iii) in the case of any criminal proceeding, has no reasonable cause to believe his conduct was unlawful. Subject to certain exceptions, a director or officer may not be indemnified if he is found liable to the corporation or if he is found liable on the basis that he improperly received a personal benefit. Under Texas law, reasonable expenses incurred by a director or officer may be paid or reimbursed by the corporation in advance of a final disposition of the proceeding after the corporation receives a written affirmation by the director or officer of his good faith belief that he has met the standard of conduct necessary for indemnification and a written undertaking by or on behalf of the director or officer to repay the amount if it is ultimately determined that the director or officer is not entitled to indemnification by the corporation. Texas law requires a corporation to indemnify a director or officer against reasonable expenses incurred in connection with the proceeding to which such director or officer is named defendant or respondent because he is or was a director or officer if he is wholly successful in defense of the proceeding. Texas law also permits a corporation to purchase and maintain insurance or another arrangement on behalf of any person who is or was a director or officer against any liability asserted against him and incurred by him in such a capacity or arising out of his status as such a director or officer, whether or not the corporation would have the power to indemnify him against that liability under Article 2.02-1 of the TBCA. Tri-Union's Amended and Restated Articles of Incorporation provide that the liability of directors for monetary damages for an act or omission in the director's capacity as a director shall be limited to the fullest extent permissible under Texas law. Texas law does not permit exculpation of liability in the case of (i) a breach of the director's duty of loyalty to the corporation or its shareholders, (ii) an act or omission not in good faith that constitutes a breach of duty of the director to the corporation or that involves intentional misconduct or a knowing violation of the law, (iii) a transaction from which a director received an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director's office or (iv) an act or omission for which the liability of the director is expressly provided by statute. Pursuant to Tri-Union's bylaws, it has a duty to indemnify directors and board observers to the fullest extent permitted by Texas law. Tri-Union may indemnify its officers, employees and agents to the same scope and effect as the foregoing indemnification of directors and board observers. In addition, Tri-Union may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of us or another corporations, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not Tri-Union would have the power to indemnify such person against such expense, liability or loss as permitted by law. The above discussion is not intended to be exhaustive and is respectively qualified in its entirety by the TBCA and Tri-Union's Amended and Restated Articles of Incorporation and bylaws. Tri-Union Operating Company Section 145 of the Delaware General Corporation Law ("DGCL") provides that a Delaware corporation may indemnify any person who is, or is threatened to be made, a party to any II-1 threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in right of such corporation), by reason of the fact that such person was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amount paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation's best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was illegal. A Delaware corporation may also indemnify any person who is, or is threatened to be made, a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent or another corporation or enterprise. The indemnity may include expenses (including attorneys' fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in a manner he reasonably believed to be in or not opposed to the corporation's best interests except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. In addition, where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director has actually and reasonably incurred. Section 145 of the DGCL also authorizes the corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability under the provisions of Delaware law.

UNDERTAKINGS. (a) The undersigned Registrants hereby undertake: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed II-3 that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in this effective Registration Statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement; (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrants hereby undertake that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrants' Annual Report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrants pursuant to the provisions referred to in Item 20 of this Registration Statement, or otherwise, the Registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrants of expenses incurred or paid by a director, officer or controlling person of the Registrants in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrants will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. (d) The undersigned Registrants hereby undertake to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means.
