FORWARD-LOOKING STATEMENTS
     The United States Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for certain forward-looking statements. Such forward-looking statements are based upon the current expectations of CanArgo and speak only as of the date made. These forward-looking statements involve risks, uncertainties and other factors. The factors discussed elsewhere in this Annual Report on Form 10-K, as amended, are among those factors that in some cases have affected CanArgo’s historic results and could cause actual results in the future to differ significantly from the results anticipated in forward-looking statements made in this Annual Report on Form 10-K, as amended, future filings by CanArgo with the Securities and Exchange Commission, in CanArgo’s press releases and in oral statements made by authorized officers of CanArgo. When used in this Annual Report on Form 10-K,as amended, the words “estimate,” “project,” “anticipate,” “expect,” “intend,” “believe,” “hope,” “may” and similar expressions, as well as “will,” “shall” and other indications of future tense, are intended to identify forward-looking statements. Few of the forward-looking statements in this Report deal with matters that are within our unilateral control. Acquisition, financing and other agreements and arrangements must be negotiated with independent third parties and, in some cases, must be approved by governmental agencies. These third parties generally have interests that do not coincide with ours and may conflict with our interests. Unless the third parties and we are able to compromise their various objectives in a mutually acceptable manner, agreements and arrangements will not be consummated.
EXPLANATORY NOTE
     CanArgo Energy Corporation (the “Company”) is hereby amending this Annual Report on Form 10-K for the fiscal year ended December 31, 2005 (the “Report”), solely to revise Items 6, 8, 9 and 15 of Part II of the Report as hereinafter set forth. The revisions are intended to respond to the comments of the staff of the Securities and Exchange Commission resulting from their recent review of the Company’s Annual Report on Form 10-K. This Amendment No. 1 to the Report continues to speak as of the date of the Report, and we have not updated the disclosures contained in this Amendment No. 1 to the Report to reflect any events that occurred at a date subsequent to the filing of the Report. The filing of this Amendment No. 1 to the Report is not a representation that any statements contained in items of the Report other than that information being amended are true or complete as of any date subsequent to the date of the Report. The revision does not affect the remaining information set forth in the Report, the remaining portions of which have not been amended.

ITEM 9A. CONTROLS AND PROCEDURES.
Management’s Responsibility for Financial Statements
     Our management is responsible for the integrity and objectivity of all information presented in this Annual Report. The consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States of America and include amounts based on management’s best estimates and judgments. Management believes the consolidated financial statements fairly reflect the form and substance of transactions and that the financial statements fairly represent the Company’s financial position and results of operations. The Audit Committee of the Board of Directors, which is composed solely of independent directors, meets regularly with the independent auditors, L J Soldinger Associates LLC and representatives of management to review accounting, financial reporting, internal control and audit matters, as well as the nature and extent of the audit effort. The Audit Committee is responsible for the engagement of the independent auditors. The independent auditors have free access to the Audit Committee.
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2005. Based on that evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures are not effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms and to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.
Management’s Report on Internal Control over Financial Reporting
     Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting, is defined in the rules promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s Board, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting procedures (“GAAP”) and includes those policies and procedures that:
    pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;
 
    provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with US GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and Directors of the Company; and
 
    provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

     A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
     Under the supervision and with the participation of our management, including our principal executive, financial and accounting officers, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2005 based on the framework in “Internal Control — Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission.
     A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of our annual or interim financial statements would not be prevented or detected. As of December 31, 2005, we have concluded that our internal control over financial reporting was ineffective as of December 31, 2005 and that we have material weaknesses in each of the following areas:
1. Financial Statement Close Process
     The Company’s controls over the financial reporting close process were not consistently applied. As a result, the Company has a material weakness related to its ability to compile and review accurate financial statements.
    The financial statement close process relies heavily upon manual rather than automated system process controls and places significant reliance on spreadsheets;
 
    Formal policies and procedures in many functions including maintenance of the Chart of Accounts, financial statement close, purchasing, payroll, and cash management operations do not exist;
 
    Preparation and review of account reconciliations, particularly in Georgia and Kazakhstan, are not performed; and
 
    There is no review, reconciliation or approval of various schedules and reconciliations, including the transfer of amounts from subsidiary trial balances to consolidating spreadsheets prepared to support the financial close and disclosure processes
     These material weaknesses related to the financial statement close process affect all of the Company’s significant accounts and could result in a material misstatement to the Company’s annual or interim consolidated financial statements that would not be prevented or detected.
2. Disclosure Controls
     The Company’s disclosure controls and procedures were not effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms and to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including chief executive officer and chief financial officer, as appropriate to allow timely decisions. Inadequate controls include the lack of procedures used for identifying, determining, and calculating required disclosures and other supplementary information requirements.
3. Information Technology
     The Company did not adequately implement certain controls over information technology, including certain spreadsheets, used in its core business and financial reporting. These areas included logical access security controls to financial applications, segregation of

duties and backup and recovery procedures. The Company’s controls over the completeness, accuracy, validity, restricted access, and the review of certain spreadsheets used in the period-end financial statement preparation and reporting process was not designed appropriately. This material weakness affects the Company’s ability to prevent improper access and changes to its accounting records.
4. Production
     The Company did not have effective controls and procedures to ensure that revenues and associated costs from the sales of its products based on production and transmission records between the Company and its third party production sharing partner were reconciled or correctly recognized. Controls associated with the product transmission are performed by the third party production sharing partner and there is no evidence that these controls have been reviewed by the Company.
     Deficiencies in the Company’s internal controls and procedures relating to the recording of production do not allow assurance that revenues and costs are recognized in accordance with generally accepted accounting principles.
5. Inventory Management
     The Company did not maintain a control environment that fully emphasized the establishment of, adherence to, or adequate communication regarding appropriate internal control for the management of its inventory, including the lack of documented procedures to update and review the material master file and valuation table or compare the cost of inventory to net realizable value.
     These weaknesses increased the likelihood of potential material errors in the Company’s financial reporting.
6. Entity Level Controls
     As evidenced by the material weaknesses described above, entity-level controls related to the control environment, risk assessment, monitoring function and dissemination of information and communication activities did not operate effectively. This includes a lack of adequate mechanisms for anticipating and identifying financial reporting risks and for reacting to changes in the operating environment that could have a potential effect on financial reporting. Such entity level controls, and a comprehensive monitoring of internal controls, are part of the framework to ensure that the designed system of internal control is operating effectively to ensure that significant transactions are adequately identified, recorded and disclosed.
     As a result, misappropriation of assets and misstatements in the financial statements could occur and not be prevented or detected by the Company’s controls in a timely manner. In the light of the review Management, in consultation with the Audit Committee, is reviewing the most cost effective way to address the issues raised. Management considers that remediation measures will include the appointment of a Group Compliance Officer with responsibility for ensuring the preparation, review, testing and updating of the appropriate policies, procedures and standards. Recruitment of a Country Financial Controller in Kazakhstan to strengthen group reporting is underway.
     CEO and CFO Certifications — The Certifications of our CEO and CFO which are attached as Exhibits 31(1) and 31(2) to this Report include information about our disclosure controls and procedures and internal control over financial reporting. These Certifications should be read in conjunction with the information contained in this Item 9A for a more complete understanding of the matters covered by the Certifications.
Changes in Internal Control over Financial Reporting
     There were no changes in our internal control in the fourth quarter.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and
Stockholders of CanArgo Energy Corporation
     We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control over Financial Reporting, that CanArgo Energy Corporation did not maintain effective internal control over financial reporting as of 31 December 2005, because of the effect of the Material Weaknesses Identified in Management’s Assessment, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organization of the Treadway Commission (COSO). CanArgo Energy Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the company’s internal control over financial reporting based on our audit.
     We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
     A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
     Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
     A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. The following material weaknesses have been identified and included in management’s assessment.
Information Technology
     The Company did not adequately implement certain controls over information technology, including certain spreadsheets, used in its core business and financial reporting. These areas included logical access security controls to financial applications, segregation of duties and backup and recovery procedures. The Company’s controls over the completeness, accuracy, validity, restricted access, and the review of certain spreadsheets used in the period-end financial statement preparation and reporting process was not designed appropriately. This material weakness affects the Company’s ability to prevent improper access and changes to its accounting records.

Financial Reporting Close Process
     The Company’s controls over the financial reporting close process were not consistently applied. As a result, the Company has a material weakness related to its ability to compile and review accurate financial statements.
     1. The financial statement close process relies heavily upon manual rather than automated system process controls and places significant reliance on uncontrolled spreadsheets;
     2. Formal policies and procedures in many functions including maintenance of the Chart of Accounts, financial statement close, purchasing, payroll, and cash management operations do not exist;
     3. Preparation and review of account reconciliations, particularly in Georgia and Kazakhstan, are not performed; and
     4. There is no review, reconciliation or approval of various schedules and reconciliations, including the transfer of amounts from subsidiary trial balances to consolidating spreadsheets prepared to support the financial close and disclosure processes
     These material weaknesses related to the financial statement close process affect all of the Company’s significant accounts and could result in a material misstatement to the Company’s annual or interim consolidated financial statements that would not be prevented or detected.
Disclosure
     The Company’s disclosure controls and procedures were not effective in providing reasonable assurance that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Inadequate controls include the lack of procedures used for identifying, determining and calculating required disclosures and other supplementary information requirements.
Production
     The Company did not have effective controls and procedures to ensure that revenues and associated costs from the sales of its products based on production and transmission records between the Company and its third party production sharing partner were reconciled or correctly recognized. Controls associated with the product transmission are performed by the third party production sharing partner and there is no evidence that these controls have been reviewed by the Company.
     Deficiencies in the Company’s internal controls and procedures relating to the recording of production do not allow assurance that revenues and costs are recognized in accordance with generally accepted accounting principles.
Inventory Management
     The Company did not maintain a control environment that fully emphasized the establishment of, adherence to, or adequate communication regarding appropriate internal control for the management of its inventory, including the lack of documented procedures to update and review the material master file and valuation table or compare the cost of inventory to net realizable value.
     These weaknesses increased the likelihood of potential material errors in the Company’s financial reporting.
Entity Level
     As evidenced by the material weaknesses described above, entity-level controls related to the control environment, risk assessment, monitoring function and dissemination of information and communication activities did not operate effectively. This includes a lack of adequate mechanisms for anticipating and identifying financial reporting risks and for reacting to changes in the operating environment that could have a potential effect on financial reporting. Such entity level controls, and a comprehensive monitoring of internal controls, are part of the framework to ensure that that the designed system of internal control is operating effectively to ensure that significant transactions are adequately identified, recorded and disclosed.
     As a result, misappropriation of assets and misstatements in the financial statements could occur and not be prevented or detected by the Company’s controls in a timely manner.

     We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2005 consolidated financial statements of CanArgo Energy Corporation and our report dated 9 March 2006 expressed an unqualified opinion.
     These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2005 financial statements, and this report does not affect our report dated 9 March 2006 on those financial statements.
     In our opinion, management’s assessment that CanArgo Energy Corporation did not maintain effective internal control over financial reporting as of 31 December 2005, is fairly stated, in all material respects, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also, in our opinion, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, CanArgo Energy Corporation has not maintained effective internal control over financial reporting as of 31 December 2005, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Board of Directors and Shareholders
CanArgo Energy Corporation
St Peter Port, Guernsey, British Isles
     We have audited the accompanying consolidated balance sheets of CanArgo Energy Corporation as of December 31, 2005 and 2004, and the related consolidated statements of operations and comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2005. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.
     We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statements presentation. We believe that our audit provides a reasonable basis for our opinion.
     In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of CanArgo Energy Corporation as of December 31, 2005 and 2004, and its consolidated results of operations, changes in stockholders’ equity and its cash flows for each of the years in the three-year period ended December 31, 2005 in conformity with accounting principles generally accepted in the United States of America.
     We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of CanArgo Energy Corporation internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 9, 2005 expressed an unqulaified opinion on management’s assessment of internal control over financial reporting and an adverse opinion on the effectiveness of internal control over financial reporting.

CANARGO ENERGY CORPORATION
Notes to Consolidated Financial Statements
NOTE 1 — NATURE OF OPERATIONS
     CanArgo Energy Corporation, headquartered in Guernsey, British Isles, and its consolidated subsidiaries (collectively “CanArgo”, “we”, “our”, “us”), is an integrated oil and gas company operating predominately within Georgia and the Republic of Kazakhstan. Our principal activity is the acquisition of interests in and development of crude oil and natural gas fields.
     In 2002 and 2003, we approved a plan to sell CanArgo Standard Oil Products Limited (“CSOP”), Lateral Vector Resources Inc. (“LVR”), the Georgian American Oil Refinery Limited (“GAOR”) and a generating power unit. During 2004, CSOP, GAOR and LVR were sold. The results of these operations have been classified as discontinued for all periods presented. Net income (loss) from discontinued operations is disclosed net of taxes and minority interest for all periods presented. The generating power unit has been classified as “Assets held for sale” for all periods presented.
     In the years ended December 31, 2005 and 2004 the Company’s revenues from its Georgian operations did not cover the costs of its operations. At December 31, 2005 the Company had unrestricted cash and cash equivalents of approximately $18,541,000. In 2005 the Company experienced a net cash outflow from operations of approximately $8,269,000. In addition, the Company has a planned capital expenditure budget in 2006 of approximately $20,000,000 in Georgia. In the event that the exploration and development wells currently undergoing or waiting to undergo production testing in Georgia fail to produce enough commercially available quantities of oil and or gas, the Company may not have sufficient working capital and may have to delay or suspend its capital expenditure plans and possibly make cutbacks in its operations. There are no assurances the Company could raise additional sources of equity financing and because of the covenants contained in the Senior Secured Convertible Notes (see Note 11) the Company is restricted from incurring additional debt obligations unless it receives consent from at least 51% of the noteholders, which cannot be assured.
     In March 2006 with the private placement of the $13,000,000 Senior Subordinated Convertible Guaranteed Notes we have fully funded the currently planned budget for our operating and development expenditure in Kazakhstan for 2006.
NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
     The consolidated financial statements and notes thereto are prepared in accordance with accounting principles generally accepted in the United States. All amounts are in U.S. dollars. Certain items for prior years in the consolidated financial statements have been reclassified to conform to the current year’s presentation. There was no effect on the reported net loss as a result of these reclassifications.
Consolidation
     The consolidated financial statements include the accounts of CanArgo Energy Corporation and its majority owned subsidiaries. All significant intercompany transactions and accounts have been eliminated. Investments in less than majority owned corporations and corporate like entities in which we exercise significant influence are accounted for using the equity method. Entities in which we do not have significant influence are accounted for using the cost method.
Equity Method
     Under the guidance of Emerging Issue Task Force D-46, “Accounting for Limited Partnership Investments” the Company uses the equity method to account for all of its limited partnership interests in oil and gas ventures that exceed 5% and is less than 50%. Under the equity method of accounting, the Company’s proportionate share of the investees’ net income or loss is included in “Equity Income from Investments” in the consolidated statements of operations. Any excess of the carrying value of the investment and loan advances over the underlying net equity of the investee is evaluated each reporting period for impairment.

F - 9


Table of Contents

     In accordance with Emerging Issues Task Force (“EITF”) 98-13 “Accounting by an Equity Method Investor for Investee Losses When the Investor has Loans to and Investments in Other Securities of the Investee,” and 99-10 “Percentage Used to Determine the Amount of Equity Method Losses,” in the event that minority interest losses exceed stockholders’ equity for the majority interest, the excess minority interest loss is recorded against loan advances or other forms of equity invested in the subsidiary. In accordance with the requirements of EITF 99-10 the Company has chosen to account for the percentage of losses to be applied to reduce its loan balance based on its ownership percentage and not on its relative percentage of investment in each security class across all investors.
Use of Estimates in the Preparation of Financial Statements
     The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates, judgements and assumptions that affect 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. Actual results could differ from those estimates.
     Management believes that it is reasonably possible the following material estimates affecting the financial statements could significantly change in the coming year: (1) estimates of proved oil and gas reserves, (2) estimates as to the expected future cash flow from proved oil and gas properties, and (3) estimates of future dismantlement and restoration costs.
Cash and Cash Equivalents
     Cash and cash equivalents, of which include all liquid investments with an original maturity of three months or less are considered to be cash equivalents.
Fair Value of Financial Instruments
The carrying amounts reflected in the consolidated balance sheets for cash and equivalents, short-term receivables and short-term payables approximate their fair value due to the short maturity of the instruments. The carrying value of the short-term note payable with detachable warrants reflects a discount for the value of warrants and was $964,142 at December 31, 2005. The face amount of the note payable is $1,050,000. The carrying value of the short-term debt approximates fair value as the debt bears interest at a market rate. The carrying and face value of $25,000,000 of the long-term debt approximates fair value as the debt bears interest at a market rate. Please refer to Note 11 Loans Payable and Long Term Debt for a more detailed discussion of the accounting treatment of the long-term debt.
Concentration of Credit Risk
     Although our cash and temporary investments and accounts receivable are exposed to potential credit loss, we do not believe such risk to be significant. Even though a substantial amount of funds were in accounts at financial institutions which were not covered under bank guarantees, management does not believe that maintaining balances in excess of bank guarantees resulted in a significant risk to us.
     As an independent oil and gas producer, our revenue, profitability and future rate of growth are substantially dependent upon prevailing prices for oil and gas, which are dependent upon numerous factors beyond our control, such as economic, political and regulatory developments and competition from other sources of energy. The energy markets have historically been very volatile, and there can be no assurance that oil and gas prices will not be subject to wide fluctuations in the future. A substantial or extended decline in oil and gas prices could have a material adverse effect on our financial position, results of operations, cash flows and our access to capital and on the quantities of oil and gas reserves that may be economically produced.
     We sold approximately 90%, 82% and 92% of our oil to 2 customers, 4 customers and 3 customers respectively in 2005, 2004 and 2003. Management believes that due to the global nature of the market for oil and gas, that the loss of any customer or group of customers would not have a material effect on its sales.
Reclassification
     Certain items in the consolidated financial statements have been reclassified to conform to the current year presentation. There was no effect on reported net loss as a result of these reclassifications.

F - 10


Table of Contents

Accounts Receivable and Allowance for Doubtful Debts
     Accounts receivable are carried at the amount owed by customers, reduced by an allowance for estimated amounts that may not be collectible in the future. The allowance for doubtful accounts is estimated based upon historical write-off percentages, known problem accounts, and current economic conditions. Accounts are written off against the allowance for doubtful accounts when we determine that amounts are not collectable and recoveries of previously written-off accounts are recorded when collected.
Inventories
     Inventories of crude oil are valued at the lower of average cost or net realizable value. Inventory costs include expenditures and other charges (including depreciation, depletion and amortization) directly and indirectly incurred in bringing the inventory to its existing condition and location. Selling expenses and general and administrative expenses are reported as period costs and excluded from inventory cost.
Capital Assets
     Capital assets are recorded at cost less accumulated provisions for depreciation, depletion and amortization unless the carrying amount is viewed as not recoverable in which case the carrying value of the assets is reduced to the estimated recoverable amount. See “Impairment of Long-Lived Assets” below. Expenditures for major renewals and betterments, which extend the original estimated economic useful lives of applicable assets, are capitalized. Expenditures for normal repairs and maintenance are charged to expense as incurred. The cost and related accumulated depreciation of assets sold or retired are removed from the accounts and any gain or loss thereon is reflected in operations. Unproved properties are not deemed to be impaired until the right to drill on those properties is lost and planned development has ceased.
     Oil And Gas Properties — CanArgo and the unconsolidated entities (for which it accounts using the equity method) account for oil and gas properties and interests under the full cost method. Under the full cost method, all acquisition, exploration and development costs, including certain directly related employee costs incurred for the purpose of finding oil and gas are capitalized and accumulated in pools on a country—by—country basis. Capitalized costs include the cost of drilling and equipping productive wells, including the estimated costs of dismantling and abandoning these assets, dry hole costs, lease acquisition costs, seismic and other geological and geophysical costs, delay rentals and costs related to such activities. Employee costs associated with production and other operating activities and general corporate activities are expensed in the period incurred.
     Where proved reserves are established, capitalized costs are limited on a country—by—country basis (the ceiling test). The ceiling test is calculated as the sum of the present value of future net cash flows related to estimated production of proved reserves, using end—of—the-current-period prices, discounted at 10%, and takes into account expected future costs to develop proved reserves, and operating expenses and income taxes. Under the ceiling test, if the capitalized cost of the full cost pool exceeds the ceiling limitation, the excess is charged as an impairment expense.
     Unit-of-production depreciation is applied to capitalized cost of the full cost pool. Unit-of-production rates are based on the amount of proved developed reserves of oil, gas and other minerals that are estimated to be recoverable from existing facilities using current operating methods.
     We utilize a single cost center for each country where we have operations for amortization purposes. Any conveyances of properties are treated as adjustments to the cost of oil and gas properties with no gain or loss recognized unless the operations are suspended in the entire cost center or the conveyance is significant in nature.
     The costs of investments in unproved properties and portions of costs associated with major development projects are excluded from the depreciation, depletion and amortization (“DD&A”) calculation until the project is evaluated.
     Unproved property costs include leasehold costs, seismic costs and other costs incurred during the exploration phase. In areas where proved reserves are established, significant unproved properties are evaluated periodically, but not less than annually, for impairment. If a reduction in value has occurred, these property costs are considered impaired and are transferred to the related full cost pool. Unproved properties whose acquisition costs are not individually significant are aggregated, and the portion of such costs estimated to be ultimately nonproductive, based on experience, is amortized to the full cost pool over an average holding period.

F - 11


Table of Contents

     In countries where the existence of proved reserves has not yet been determined, leasehold costs, seismic costs and other costs incurred during the exploration phase remain capitalized in unproved property cost centers until proved reserves have been established or until exploration activities cease or impairment and reduction in value occurs. If exploration activities result in the establishment of a proved reserve base, amounts in the unproved property cost center are reclassified as proved properties and become subject to depreciation, depletion and amortization and the application of the ceiling test. If exploration efforts in a country are unsuccessful in establishing proved reserves, it may be determined that the value of exploratory costs incurred there have been permanently diminished in part or in whole. Therefore, based on the impairment evaluation and future exploration plans, the unproved property cost centers related to the area of interest could be impaired, and accumulated costs charged against earnings.
     Property and Equipment — Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the assets ranging from three to five years for office furniture and equipment to three to fifteen years for oil and gas related equipment.
     Property and Equipment (CanArgo Standard Oil Products) — Depreciation of property and equipment at CanArgo Standard Oil Products’ petrol stations and additions thereto were depreciated over the estimated useful lives of the assets ranging from ten to fifteen years until operations were reclassified as discontinued.
Revenue Recognition
     Continuing operations — We recognize revenues when hydrocarbons have been produced and delivered and payment is reasonably assured.
     Discontinued operations — We recognize revenues when goods have been delivered, when services have been performed, or when hydrocarbons have been produced and delivered and payment is reasonably assured.
Foreign Operations
     Our future operations and earnings will depend upon the results of our operations in the Georgia. There can be no assurance that we will be able to successfully conduct such operations, and a failure to do so would have a material adverse effect on our financial position, results of operations and cash flows. Also, the success of our operations will be subject to numerous contingencies, some of which are beyond management control. These contingencies include general and regional economic conditions, prices for crude oil and natural gas, competition and changes in regulation. Since we are dependent on international operations, specifically those in Georgia, we will be subject to various additional political, economic and other uncertainties. Among other risks, our operations may be subject to the risks and restrictions on transfer of funds, import and export duties, quotas and embargoes, domestic and international customs and tariffs, and changing taxation policies, foreign exchange restrictions, political conditions and regulations.
Foreign Currency Translation
     The U.S. dollar is the functional currency for our upstream operations and the Lari is the functional currency for marketing operations. All monetary assets and liabilities denominated in foreign currency are translated into U.S. dollars at the rate of exchange in effect at the balance sheet date and the resulting unrealized translation gains or losses are reflected in operations. Non-monetary assets are translated at historical exchange rates. Revenue and expense items (excluding depreciation and amortization which are translated at the same rates as the related assets) are translated at the average rate of exchange for the year.

Table of Contents

Income Taxes
     We recognize deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the financial statements or tax returns. Deferred tax liabilities and assets are determined based on the difference between the financial statement and the tax bases of assets and liabilities using enacted rates in effect for the years in which the differences are expected to reverse. Valuation allowances are established, when appropriate, to reduce deferred tax assets to the amount expected to be realized.
Impairment of Long-Lived Assets
     The Company evaluates its long-lived assets for impairment using the guidance of Statement of Financial Accounting Standard (“SFAS”) No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. SFAS No. 144 establishes a single accounting model for long-lived assets to be disposed of by sale and requires that those long-lived assets be measured at the lower of carrying amount or fair value less cost to sell, whether reported in continuing operations or in discontinued operations.
Dismantlement, Restoration and Environmental Costs
     We recognize liabilities for asset retirement obligations associated with tangible long-lived assets, such as producing well sites, with a corresponding increase in the related long-lived asset. The asset retirement cost is depreciated along with the property and equipment in the full cost pool. The asset retirement obligation is recorded at fair value and accretion expense, recognized over the life of the property, increases the liability to its expected settlement value. If the fair value of the estimated asset retirement obligation changes, an adjustment is recorded for both the asset retirement obligation and the asset retirement cost. The Company’s asset retirement obligations consist of costs related to the plugging of wells, the removal of facilities and equipment, and site restoration on oil and gas properties. Capitalized costs are depleted as a component of the full cost pool using the units of production method.
     Upon adoption of this standard in 2003 we recorded the fair value of its existing asset retirement obligations as if the liabilities had been initially accounted for in accordance with SFAS 143 using assumptions present at the date of adoption. The income statement effect of this treatment was recorded as a cumulative effect in accounting principle in the period of adoption. During 2003, we recorded a credit to income for the cumulative effect of change in accounting principle of $41,290, increased long-term liabilities to recognise our total obligation and increased net capital assets in accordance with the provisions of SFAS No. 143 to the amount of $82,000. We did not recognise deferred tax expense on the SFAS 143 credit as the group is in a net deferred tax asset position against which full allowance has been made as it is considered more likely than not that the deferred tax asset will not be realised. There was no impact on our cash flows as a result of adopting SFAS No. 143. The asset retirement obligation, which is included on the consolidated balance sheet in provision for future site restoration, was $523,000 at December 31, 2005, which includes $58,800 for retirement obligations related to our acquired Tethys operations.

Stock-Based Compensation Plans
     Effective January 1, 2003, we adopted SFAS No. 123 Accounting For Stock-Based Compensation (“SFAS 123”), as amended by SFAS No. 148 Accounting for Stock-Based Compensation — Transition and Disclosure — an amendment of FASB Statement No. 123. We elected to utilize the “prospective” method of transitioning from the intrinsic value to the fair value method of accounting for stock-based compensation. Stock based awards in existence prior to 2003 will continue to be accounted for under APB Opinion No. 25 Accounting for Stock Issued to Employees, unless they are re-priced or modified.
     In accordance with SFAS 123, compensation expense for awards granted on or after January 1, 2003, have been measured by the fair value of the award at the date of grant and recognized over the vesting or requisite service period. The fair value of awards in the form of stock options is estimated using an option-pricing model.

F - 13


Table of Contents

     Under Opinion No. 25, stock-based employee compensation cost was not recognized in net income when stock options granted had an exercise price equal, or greater, to the market value of the underlying common stock on the date of grant.
     The pro forma information regarding net loss and net loss per share is required by SFAS 123 and has been determined as if we had accounted for our employee stock options under the fair value method of that statement. The fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted average assumptions for 2003; risk free interest rate of 2.91%; dividend yield of 0%; volatility factors of the expected market price of CanArgo common stock of 80.47; and a weighted-average expected life of the options of four years. The following table illustrates the pro forma effect on net loss and net loss per share if the fair value based method had been applied to all outstanding and unvested awards for the year ended December 31, 2003:

     In December 2004, the Financial Accounting Standards Board (FASB) issued a revised Statement of Financial Accounting Standards No. 123 (FAS 123R), “Share-based Payment”, which will become effective for the Company as of January 1, 2006. Adoption of FAS 123R will not materially change the Corporation’s existing accounting practices or the amount of share-based compensation recognized in earnings. The Company expects that for options issued in 2005 and 2004 with graded vesting schedules, that each vesting tranche will remain unexercised until the expiration of the option and has thus chosen to amortize compensation costs recorded for those options using the straight line method.
     The Company accounts for options issued with redemption features in accordance with Accounting Series Release 268 — Presentation in Financial Statements of “Redeemable Preferred Stocks” and EITF D-98: Classification and Measurement of Redeemable Securities. Adjustments which are made to the amounts reflected in the temporary equity category for options with redemption features are made against additional paid in capital until such time when the intrinsic value exceeds the fair value originally recorded in which case the excess intrinsic value would be recorded as stock based compensation. In 2005 the temporary equity increased by $1,396,250 and this amount was less than the fair value originally recorded.
Recently Issued Pronouncements
     In March 2005, the FASB issued Interpretation No. 47, “Accounting for Conditional Asset Retirement Obligations,” which clarifies that an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value can be reasonably estimated even though uncertainty exists about the timing and (or) method of settlement. The Company is required to adopt Interpretation No. 47 prior to the end of 2006 and its adoption is not expected to have a significant effect on the Company’s results of operations or financial condition.
     In November 2004, the FASB issued SFAS No. 151 “Accounting for Inventory Costs” that amends Accounting Research Bulletin (ARB) No. 43, Chapter 4, “Inventory Pricing” to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). SFAS 151 requires that those items be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal” and requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. The Company is required to adopt SFAS No. 151 in the beginning of 2006 and its adoption is not expected to have a significant effect on the Company’s results of operations or financial condition.
     In December 2004, the FASB issued SFAS No. 153 “Exchanges of Nonmonetary Assets” that amends Accounting Principles

F - 14


Table of Contents

Board (APB) Opinion No. 29, “Accounting for Nonmonetary Transactions” and Amends FAS 19 “Financial Accounting and Reporting by Oil and Gas Producing Companies”, paragraphs 44 and 47(e). ARB No. 29 is based on the principle that exchanges of nonmonetary assets should be measured based on the fair value of the assets exchanged and SFAS 153 amended ABP 29 to eliminate the exception for nonmonetary exchanges of similar productive assets and replaced it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. The Company is required to adopt SFAS No. 153 for nonmonetary asset exchanges occurring in the first quarter of 2006 and its adoption is not expected to have a significant effect on the Company’s results of operations or financial condition.
     In May 2005, the FASB issued SFAS No. 154 “Accounting Changes and Error Corrections” to replace ABP No. 20 “Accounting Changes” and SFAS No. 3 “Reporting Accounting Changes in Interim Financial Statements.” Opinion 20 previously required that most voluntary changes in accounting principle be recognized by including in net income of the period of the change the cumulative effect of changing to the new accounting principle. SFAS 154 requires retrospective application to prior periods’ financial statements of changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. When it is impracticable to determine the period-specific effects of an accounting change on one or more individual prior periods presented, SFAS 154 requires that the new accounting principle be applied to the balances of assets and liabilities as of the beginning of the earliest period for which retrospective application is practicable and that a corresponding adjustment be made to the opening balance of retained earnings (or other appropriate components of equity or net assets in the statement of financial position) for that period rather than being reported in an income statement. When it is impracticable to determine the cumulative effect of applying a change in accounting principle to all prior periods, SFAS 154 requires that the new accounting principle be applied as if it were adopted prospectively from the earliest date practicable. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The implementation of FAS 154 is not expected to have a significant effect on the Company’s results of operations or financial condition.
     In November 2005, accounting standards were revised to provide guidance for determining and measuring other-than-temporary impairments of debt and equity securities. The new guidance is effective for reporting periods beginning after December 15, 2005. At December 31, 2005, available-for-sale investments in our marketable securities had unrealized losses totaling $0.9 million which are recorded in Other Accumulated Comprehensive Income. We do not believe that the securities with unrealized losses as of December 31, 2005 currently meet the criteria for recognizing the loss under existing other-than-temporary guidance.
NOTE 3 — BUSINESS COMBINATIONS
Tethys Petroleum Investments Limited
     On June 7, 2005, CanArgo made an offer to acquire 55% of the ordinary share capital of Tethys Petroleum Investments Limited (“Tethys”) which was held by Provincial Securities Limited (“Provincial”) and Vando International Finance Limited (“Vando”) for consideration of 11,000,000 CanArgo common shares. On June 9, 2005 CanArgo issued 5,500,000 shares to Provincial, of which Russell Hammond (one of our non-executive directors) is Investment Advisor and 5,500,000 shares to Vando in connection with this transaction. At June 7, 2005, the closing price of CanArgo total common stock was $0.76 giving the common stock consideration a market value of $8,360,000 for the 11 million shares. On completion of the acquisition, CanArgo held 100% of the ordinary share capital of Tethys through its subsidiary CanArgo Limited and Tethys became a wholly-owned subsidiary of the Company. We have recorded our interest as if the acquisition occurred on June 30, 2005. Tethys’ primary asset was its 70% interest in BN Munai, a Kazakhstan limited partnership.
     The purchase price was allocated to the net assets of Tethys as follows:
         
Cash
  $ 609,553  
Oil and Gas Properties
    6,418,115  
Other Current Assets
    1,688,294  
Current Liabilities
    (297,162 )
Provision for future site restoration
    (58,800 )
 
     
 
  $ 8,360,000  
 
     
     The principal reason for the purchase was to secure Tethys’ current interests in a proven gas field and significant exploration areas in western Kazakhstan.
     The Company has included the results of operations of Tethys in the consolidated financial statements starting July 1, 2005.

Kul-Bas LLP owns an Exploration contract, which is for a period of 25 years, with an initial six year exploration period, covering an unexplored area of approximately 2.75 million acres (11,133 km(2)) surrounding the Akkulka area. The purchase price of the company reflected the fair value of the unevaluated property and was allocated to unevaluated oil and gas properties.

     In the first quarter of 2005 we funded a certificate of deposit in the amount of $3,900,000 to secure the issuance of a letter of credit as required under the rig rental and drilling contract we entered into with Saipem, S.p.A. Under the terms of the letter of credit $1,100,000 was released and became unrestricted cash in July 2005. The remaining deposit was due to become unrestricted in January 2006. The letters of credit were extended until June and August 2006 and will become unrestricted then.
     In the third quarter of 2005, we deposited approximately $300,000 to secure the issuance of a letter of credit as required under the drilling contract we entered into with Baker Hughes International.
     Restricted cash of $1,400,000 at December 31, 2004 related to money placed in a third party escrow account in October 2004, to fund part of the horizontal development program, of which WEUS Holding Inc., a subsidiary of Weatherford International Limited (“Weatherford”) was the primary contractor, at the Ninotsminda and Samgori Fields in Georgia. These funds were disbursed to the contractor in July 2005 in satisfaction of liabilities for drilling services provided to the Company in 2005 in accordance with the terms of the escrow agreement.
NOTE 5 — ACCOUNTS RECEIVABLE
     Accounts receivable consisted of the following at December 31:

     Bad debt expense for 2005, 2004 and 2003 was $145,829, $5,803 and $170,000 respectively, and is reflected under other income in the statement of operations.
     In September 2004, a blow-out occurred at the N100 well on the Ninotsminda Field. Our insurers will cover 80% of the costs associated with the blow out up to a maximum cover of $2,500,000. We received $800,000 from our insurers in the second quarter of 2005 in respect of costs incurred to date. As of December 31, 2005 and 2004, $31,755 and $1,047,359 was recorded as a receivable, respectively.
     Included in receivables as of December 31, 2004 was $1,057,534 due from Georgian Oil Samgori Limited (“GOSL”) for its share of capital expenditure, on the planned horizontal well drilling program on the Samgori Field. We funded 100% of the costs which were mainly related to mobilizing Weatherford to Georgia for the commencement of the horizontal well drilling program. Following the failure of Weatherford to successfully complete any horizontal sidetrack development wells on the Ninotsminda Field using Under-Balanced Coiled Tubing Drilling technology, Weatherford demobilised its equipment and left Georgia in July 2005. These costs have now been transferred to oil and gas properties.

Oil and Gas Properties
     Ultimate realization of the carrying value of our oil and gas properties will require production of oil and gas in sufficient quantities and marketing such oil and gas at sufficient prices to provide positive cash flow to CanArgo, which is dependent upon, among other factors, achieving significant production at costs that provide acceptable margins, reasonable levels of taxation from local authorities, and the ability to market the oil and gas produced at or near world prices. In addition, we must mobilize drilling equipment and personnel to initiate drilling, completion and production activities. If one or more of the above factors, or other factors, are different than anticipated, we may not recover our carrying value.
     In 2005, 2004 and 2003, CanArgo did not need to write-down oil and gas properties due to the ceiling test.
     We generally have the principal responsibility for arranging financing for the oil and gas properties and ventures in which we have an interest. There can be no assurance, however, that we or the entities that are developing the oil and gas properties and ventures will be able to arrange the financing necessary to develop the projects being undertaken or to support our corporate and other activities or that such financing as is available will be on terms that are attractive or acceptable to or are deemed to be in the best interests of the Company, such entities or their respective stockholders or participants.
     The consolidated financial statements of CanArgo do not give effect to any additional impairment in the value of our investment in oil and gas properties and ventures or other adjustments that would be necessary if financing cannot be arranged for the development of such properties and ventures or if they are unable to achieve profitable operations. Failure to arrange such financing on reasonable terms or failure of such properties and ventures to achieve profitability would have a material adverse effect on our financial position, including realization of assets, results of operations, cash flows and prospects.
     Unproved property additions relate to our exploration activity in the period.
     We plan to test a substantial portion of our unproved properties for oil and gas in 2006. In the event that we do not find oil and gas, we could incur substantial impairments were the amounts to exceed our ceiling test.
Costs Not Being Amortised
     Oil and gas property costs not being amortized at December 31, 2005, for both Georgia and Kazakhstan by year that the costs were incurred are as follows:
                         
Year Ended December 31:   Exploration     Acquisition     Total Capital  
2005
  $ 16,133,409     $ 9,408,644     $ 25,542,054

  $ 36,518,709     $ 14,126,290     $ 50,644,999  
 
                 
     Unevaluated costs include $23,703,850 for the Ninotsminda Field. $2,000,000 was allocated to the Cretaceous on acquisition prior to 2003. The structure named Manavi was proved to contain oil and gas by an original exploration well in 2003. This well was sidetracked in 2005 and now awaits testing. Another appraisal well is drilling ahead and is expected to be completed within approximately five months.
     Unevaluated costs include $16,304,554 for the Norio Field. An exploration well was completed at the end of 2005 and is currently being prepared for testing. The results of this test will determine whether further appraisal or development drilling is required.
     Unevaluated costs include $3,802,151 for the Nazvrevi Field. $2,695,145 was allocated to the Field on acquisition prior to 2003. It also includes the significant Kumisi Cretaceous gas prospect for which we recently signed a Memorandum of Understanding (“MOU”) which includes the terms of a take-or-pay natural gas supply contract with the Ministry of Energy of Georgia. This MOU provides the commercial basis for CNL to move forward with the appraisal of Kumisi and, based on this and subject to regulatory approval, CNL plans to spud a well on Kumisi between May and December of this year.

     Unevaluated costs include $9,529,588 for Tethys. $9,408,644 was allocated to unevaluated areas on acquisition in 2005. In Kazakhstan, we are in the process of completing a five well exploration program. A number of new gas discoveries have already been made & current plans are to undertake further exploration drilling in 2006.

The Company is amortizing the professional fees incurred in relation to the Senior Secured Notes over the term of the Senior Secured Notes. Professional fees of $42,312 were amortized on a straight-line basis in 2005 in connection with the Senior Secured Notes.
     As at December 31, 2004, commissions and professional fees related to the additional Ozturk Long Term Loan with Detachable Warrants and the Standby Equity Distribution Agreement (“SEDA”) dated February 11, 2004 between CanArgo and Cornell Capital Partners LP (“Cornell Capital”) were included in Prepaid financing fees.
     Fees of $25,000 and $6,250 were amortized on a straight-line basis in 2005 and 2004 respectively in connection with the Ozturk Long Term Loan with Detachable Warrants.
     Commissions and professional fees of $604,757 at December 31, 2004 relating to the SEDA dated (See note 17) February 11, 2004 between CanArgo and Cornell Capital were offset against equity in March 2005 after sufficient draw downs under the SEDA.
NOTE 10 — INVESTMENT IN AND ADVANCES TO OIL AND GAS AND OTHER VENTURES
     As discussed in Note 3, on June 9, 2005 we acquired 100% ownership of Tethys Petroleum Investments Limited and this entity is now consolidated in our financial statements. A summary of our net investment in and advances to oil and gas and other ventures consisted of the following at December 31, 2005 and December 31, 2004:

As part of this investment, ACR contributed its 70% ownership interest in Too BN Munai LLP (“BNM”) into TKI in exchange for 10% ownership of TPI and we committed to funding the day to day operations and provide management services until third party financing could be arranged in exchange for 90% ownership of TPI. BNM’s interest centers on the Akkulka exploration area and the Kyzyloi Gas Field, located in western Kazakhstan, just to the west of the Aral Sea. In the four years prior to our ownership interest, ACR drilled two deep

exploration wells inthe Akkulka area, which they plugged and abandoned after demonstrating the presence of hydrocarbons, due to funding limitations on their part. On the same day that we consummated the transaction to create TPI, we entered into an agreement to sell half of our ownership interest in TPI to Provincial Securities Limited, an investment company to which Mr. Russell Hammond, one of our non- executive directors, is an Investment Advisor, in consideration for future services of providing advice to us concerning funding the development of TPI as we intend to fund the majority of the development of the Kyzyloi Gas Field through third party financing.
     The following day we entered into a Technical Services Agreement and a Loan Agreement with TPI in which we agreed to provide our managerial expertise and to provide cash advances to fund and manage the day to day operations of TPI and to provide funding to secure additional site licenses within the vicinity of the Kyzyloi Gas Field. The advances under the agreement, both cash and the value of services we perform on behalf of TPI, bear interest at the rate of 10% per annum and are repayable immediately upon the receipt by TPI of third party financing.
     On June 9, 2005 we acquired the remaining 55% ownership of Tethys Petroleum Investments Limited, by issuing 11,000,000 shares of our common stock, valued at $8,360,000, and this entity is now consolidated in our financial statements. Prior to this, we chose to use our equity ownership percentage as the basis for recording our portion of our investees’ loss and therefore first reduced our investment of $17,366 to zero and then applied the remaining equity losses of $187,864 to reduce the carrying value of our advances to $478,632.
     In 2005 our total investment and advances amounted to $2,900,886 which consisted of cash investment and advances of $2,750,886 and $150,000 in non-cash management fees. In addition, we accrued an additional $128,293 in interest on our advances and fees to TPI during 2005.
     In 2004 our total investment and advances amounted to $683,862 which consisted of cash investment and advances of $383,862 and $300,000 in non-cash management fees. In addition, we accrued an additional $30,215 in interest on our advances and fees to TPI during 2004.
     At December 31, 2004 the carrying value of our investment and advances exceeded the underlying equity in the net assets of the investee by $190,312.

     On April 26, 2004, we entered into two loan and warrant agreements, one with Salahi Ozturk in which Mr. Ozturk advanced us $1,000,000 in exchange for which we issued to Mr. Ozturk a promissory note in the amount of $1,000,000 (“Original Loan”) and the other for $306,000 with CA Fiduciary Services, Ltd Trustee for the SP525A Settlement (“CA”), for which we issued to CA a promissory note in the amount of $306,000. The notes to Mr. Ozturk and to CA attracted interest at the rate of 7.5% per annum and had a term of six months. In addition to the promissory notes, we issued Mr. Ozturk a warrant to subscribe up to 1,000,000 shares of our common stock, with an exercise price of $1.00 per share and a term of five years from the date of grant and we issued to CA a warrant to subscribe up to 300,000 shares of our common stock, with an exercise price of $1.05 per share and a term of five years from the date of grant. In the event that the Company were to raise gross proceeds of at least $10 million in any future equity offering, these notes would become due and payable within seven days from the closing of the future equity offering. We granted Mr. Ozturk a lien covering 50% of the revenues of Ninotsminda Oil Company Limited, our 100% owned subsidiary company, (or its interest in the oil sales contract) as security for repayment of the note.

     Under Accounting Principles Board (APB) 14: “Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants” we allocated the proceeds from the issuances of the promissory note and warrants based on a fair value basis of each item. The fair value of the warrants was determined to be $754,000 for the 1,000,000 warrants issued to Mr. Ozturk and $197,040 for the 300,000 warrants issued to CA and was recorded as a discount to the value of the promissory note.
     We used the following assumptions to determine the fair value of the debt and warrants:
                 
    Ozturk Loan   CA Loan
Stock price on date of grant
  $ 0.87     $ 0.78  
Risk free rate of interest
    1.19 %     1.15 %
Expected life of warrant — months
    60       60  
Dividend rate
           
Historical volatility
    138 %     132 %
     The discounts were amortized to interest expense over the life of the promissory note using the effective interest method.
     On August 27, 2004, we entered into an amended and restated loan and warrant agreement (“Amended Agreement”) with Mr. Ozturk, amending the loan and warrant agreement between the parties dated April 26, 2004. Under the terms of the amended loan and warrant agreement, Mr. Ozturk agreed to cancel the original warrant agreement and to advance the Company an additional $1,050,000 (“Additional Loan”) and extend the maturity date of the original loan to one year from six months. The Additional Loan is repayable two years and one day from the date of the Amended Agreement unless it has previously been converted. Corporate finance fees of $50,000 were paid in respect of the Additional Loan. Interest is payable on the Additional Loan at a rate of 7.5% per annum. The first interest payment date was December 31, 2004 and included rolled up interest for the period from April 26, 2004 until December 31, 2004. The Additional Loan was convertible into shares of CanArgo Common Stock (“Conversion Stock”) at 15% above a market price of $0.60 in effect when the agreement was reached, subject to customary anti-dilution adjustments. We had the option to force conversion of the Additional Loan if our share price exceeded 160% of $0.60 (or $0.96 per share) for a period of 20 consecutive trading days. No conversion is possible for a period of one year from the date of the Amended Agreement.
     In consideration for advancing funds under the Amended Agreement and the Additional Loan, we issued to Mr. Ozturk a warrant to subscribe for 2,000,000 shares of our common stock at an exercise price 5% above the market price of our common stock on the date of grant, subject to customary anti-dilution adjustments. The new warrant was issued on August 27, 2004 and is exercisable for a period of four years commencing one year from the date of the Amended Agreement. The warrants are transferable to non-US persons and may only be exercised outside the US. The Company agreed to register the shares underlying the convertible note and warrants on a “best efforts” basis and that there were no penalties included in the agreement for failure to register or to keep registered.
     Under the provisions of Emerging Issues Task Force (“EITF”) 96-19 “Debtor’s Accounting for a Modification or Exchange of Debt Instruments”, the Company has treated the Amended Agreement as extinguishment of the Original Loan due to its determination that the provisions of the Amended Agreement represented a substantial modification of terms as defined in the EITF. The result of the extinguishment was for the Company to record a loss on extinguishment in the amount of $349,923, which represented the unamortized portion of the discount of the original loan on the date of the Amended Agreement.
     The Company’s stock price at the time of the Amended Agreement was $0.51; consequently, pursuant to EITF 98-5 “Accounting for Convertible Securities with Beneficial Conversion Features or Contingently Adjustable Conversion Ratios” and EITF 00-27 “Application of Issue No. 98-5 to Certain Convertible Instruments”, the issuance of the Additional Loan and detachable warrants resulted in a discount being recorded in the amount of $263,786, which resulted from the relative fair value of the warrants, as determined using the black-scholes model, and will be amortized over the term of the Notes using the effective interest method.
     We used the following assumptions to determine the fair value of the debt and warrants:
         
    Additional Loan
Stock price on date of grant
  $ 0.51  
Risk free rate of interest
    2.51 %
Expected life of warrant — months
    48  
Dividend rate
     
Historical volatility

     The discounts are being amortized to expense interest over the life of the loan using the effective interest method. The effective interest rate was 18.9%. As of December 31, 2005 and December 31, 2004 we had amortized $177,928 and $45,951 respectively, of the debt discount as interest expense.
     As a result of our completing an equity offering on September 22, 2004, we repaid both the Original Loan to Mr. Ozturk and the CA loan on September 30, 2004. The payoff of the CA loan resulted in our expensing the remaining unamortized debt discount for that loan. On payment of the Original Loan to Mr. Ozturk, the lien covering 50% of the revenues of Ninotsminda Oil Company Limited was terminated.
     On May 19, 2004, we signed a promissory note with Cornell Capital Partners, L.P. (“Cornell Capital”) whereby Cornell Capital agreed to advance us the sum of $1,500,000. This amount would be payable on the earlier of 180 days from the date of the promissory note or within 60 days from the date that the Registration Statement on Form S-3 filed with the SEC on May 6, 2004 (Reg. No. 333-115261) would be declared effective. If the promissory note was not repaid in full when due, interest would accrue on the outstanding principal owing at the rate of 12% per annum. We paid to Cornell Capital a commitment fee of 5% of the principal amount of the promissory note which would be set-off against the first $75,000 of fees payable by us to Cornell Capital under the Standby Equity Distribution Agreement dated February 11, 2004. The promissory note would become immediately due and payable upon the occurrence of any of the following: (i) failure to pay the amount of any principal or interest when due under the promissory note; (ii) any proceedings under any bankruptcy laws of the United States of America or under any insolvency, reorganization, receivership, readjustment of debt, dissolution, liquidation or any similar law or statute of any jurisdiction filed by or against us for all or any part of our property. The Registration Statement was declared effective on February 3, 2005; we have repaid the promissory note by making a series of takedowns in February and March 2005 under the Standby Equity Distribution Agreement.
     On April 26, 2005 we signed a promissory note with Cornell Capital whereby Cornell Capital agreed to advance us the sum of $15 million (“Promissory Note”) under the following terms:
     This $15 million and interest at a rate of 7.5% per annum was payable either in cash or using the net proceeds of drawdowns under the SEDA, within 270 calendar days from the date of the Promissory Note. Pursuant to the terms of the Promissory Note, we escrowed 25 requests for advances under the SEDA each in an amount not less than $600,000 and one advance of $289,726.03 (representing estimated interest) together with 16,273,592 shares of CanArgo common stock, as at the agreement date, 664,966 shares were already in escrow. The escrow agent released requests every 7 calendar days from May 2, 2005 provided we had not previously made a payment to Cornell Capital in cash. We had the ability at our sole discretion upon 24 hours prior written notice to Cornell Capital to repay all and any amounts due under the Promissory Note in immediately available funds and withdraw any advance notices yet to be effected.
     The Promissory Note was repaid in full in cash on August 1, 2005, all escrowed advances cancelled and 7,260,647 shares of CanArgo common stock were returned from escrow and duly cancelled on October 5, 2005. On July 25, 2005 notice was given to Cornell Capital to terminate the SEDA with effect as of August 24, 2005.
     In order to ensure timely procurement of long lead items for our drilling program in Georgia and for working capital purposes during 2004, we entered into a number of loan agreements of which those outstanding during 2005 are described below.
     Senior Secured Convertible Notes: On July 25, 2005, CanArgo completed a private placement of $25,000,000 in aggregate principal amount of our Senior Secured Convertible Notes due July 25, 2009 (the “Senior Secured Notes”) with a group of private investors arranged through Ingalls & Snyder LLC of New York City, as Placement Agent, pursuant to a Note Purchase Agreement of even date (the “Note Purchase Agreement”).
     The Company paid approximately $100,000 of legal fees for the Purchasers and a $250,000 arrangement fee to Orion Securities in connection with the Senior Secured Notes.
     The unpaid principal balance under the Senior Secured Notes bears interest (computed on the basis of a 360-day year of twelve 30-day months) (a) at increasing rates ranging from 3% from the date of issuance to December 31,2005; 10% from January 1, 2006 until December 31, 2006; and 15% from January 1, 2007 until final payment, payable semi-annually, on June 30 & December 30, commencing December 30, 2005, until the principal shall have become due and payable, and (b) at 3% above the applicable rate on any overdue payments of principal and interest,

     Pursuant to the provisions of Emerging Issue Task Force 86-15: “Increasing-Rate Debt”), the Company recognizes interest expense using the effective interest rate method, which results in the use of a constant interest rate for the life of the Senior Secured Notes. The effective interest rate is approximately 12.3% per annum. The difference between the interest computed using the actual interest rate in effect in 2005 (3% per annum) and the effective interest rate (12.3% per annum) of $1,001,041 as of December 31, 2005 has been accrued as a non-current liability.
     The Senior Secured Notes are convertible any time, in whole or in part, at the option of the Note holder, into shares of CanArgo common stock (“the Conversion Stock”) at a conversion price per share of $0.90 (the “Conversion Price”), which is subject to customary anti-dilution adjustments.
     We may, at our option, upon at least not less than 90 days and not more than 120 days prior written notice, prepay at any time and from time to time after July 31, 2006, all or any part of the Senior Secured Notes, in a principal amount of not less than $100,000 at the following Redemption Prices (expressed as percentages of the principal amount so prepaid): 105% after July 31, 2006; 104% after January 1, 2007; 103% after July 1, 2007; 102% after January 1, 2008; 101% after July 1, 2008, and 100% after January 1, 2009, together with all accrued and unpaid interest.
     The Senior Secured Notes are subject to mandatory prepayment due to a change in control of the Company, as defined by the Note Purchase Agreement.
     In connection with the execution and delivery of the Note Purchase Agreement, CanArgo entered into a Registration Rights Agreement with the Purchasers pursuant to which it agreed to register the Conversion Stock for resale under the Securities Act and indemnify the purchasers in connection with the registration.
     The Company agreed to register the shares underlying the convertible note and warrants on a “best efforts” basis and that there were no penalties included in the agreement for failure to register or to keep registered.
     The Senior Secured Notes are secured by substantially all of the assets of the Company and its subsidiaries and contain certain negative and affirmative covenants and also restricts the ability of the Company to pay dividends to its common stockholders until the loan and all accrued interest have been paid or the noteholders elect to convert their loans to common stock. All of the outstanding shares of Ninotsminda Oil Company Limited have been put into escrow and pledged. The Company cannot enter into any new borrowing arrangements without the Consent of the noteholders. Any new subsidiary created by the Company must also become party to the guarantee agreement that all material subsidiaries of CanArgo have agreed to. (See page 30 “Liquidity and Capital Resources” section of Item 2 below for a more detailed discussion of covenants).

NOTE 14 — MINORITY INTEREST
Tethys Petroleum Investments Limited
     In September 2003, together with Atlantic Caspian Resources plc (“ACR”), we formed a limited partnership, Tethys Petroleum Investments Limited (“TPI”) and its wholly owned subsidiary Tethys Kazakhstan Ltd (“TKI”). As part of this investment, ACR contributed its 70% ownership interest in BN Munai LLP (“BN Munai”) into TKI in exchange for 10% ownership of TPI and we committed to funding the day to day operations and provide management services until third party financing could be arranged in exchange for 90% ownership of TPI. BN Munai’s interest centers on the Akkulka exploration area and the Kyzyloi Gas Field, located in western Kazakhstan, just to the west of the Aral Sea. In the four years prior to our ownership interest, ACR drilled two deep exploration wells in the Akkulka area, which they plugged and abandoned after demonstrating the presence of hydrocarbons, due to funding limitations on their part. On the same day that we consummated the transaction to create TPI, we entered into an agreement to sell half of our ownership interest in TPI to Provincial Securities Limited, an investment company to which Mr. Russell Hammond, one of our non- executive directors, is an Investment Advisor, in consideration for future services of providing advice to us concerning funding the development of TPI as we intended to fund the majority of the development of the Kyzyloi Gas Field through third party financing.
     The following day we entered into a Technical Services Agreement and a Loan Agreement with TPI in which we agreed to provide our managerial expertise and to provide cash advances to fund and manage the day to day operations of TPI and to provide funding to secure additional site licenses within the vicinity of the Kyzyloi Gas Field. The advances under the agreement, both cash and the value of services we perform on behalf of TPI, bear interest at the rate of 10% per annum and are repayable immediately upon the receipt by TPI of third party financing.
     On June 9, 2005, through our acquisition of the remaining 55% of Tethys Petroleum Investments Limited (See Note 3) we acquired a 70% ownership interest in BN Munai (“BN Munai”). BN Munai has only suffered losses from inception and currently the Company is the only partner funding the current operating losses, therefore, no minority interest is recorded at December 31, 2005 for the 30% ownership not under our control. The Company does not expect the minority partners in BN Munai to contribute funds to the partnership.
     Under a loan agreement with BN Munai, TKL will take 100% of the net cash flow of the Kyzyloi development until the loan is repaid. The principal loan value of $9,389,162 plus interest of $805,451 was accrued as of the loan agreement date and was originally assigned to TKL from ACR as part of its exchange of its 70% ownership interest in BN Munai for 10% ownership of TPI. As at December 31, 2005 the principal amount of the loan outstanding was $15,518,240 plus accrued interest of $1,287,095. Interest is recorded in line with the loan agreement using a 3 month LIBOR rate as at the first business day of each quarter.
     The Company has recorded 100% of its losses in BN Munai for 2005 as it is the only funding partner.

CanArgo Norio Limited
     In September 2003, CanArgo Norio Limited (“CNL”) signed a Farm-In agreement (the “Agreement”) relating to the Norio PSA with a wholly owned subsidiary of Georgian Oil, the Georgian State Oil Company (“Georgian Oil”). Georgian Oil is already a party to the Norio PSA as the commercial representative of the State. The Agreement obligates Georgian Oil to pay up to $2,000,000 to complete the MK-72 well on the Norio prospect in return for a 15% interest in the contractor share of the Norio PSA. Georgian Oil would also have an option (the “Option”) exercisable for a limited period after completion of the well, to increase its interest to 50% of the contractor share of the Norio PSA on payment to CNL of $6,500,000.
     Coincident with the Georgian Oil farm-in, we concluded a transaction to purchase some of the minority interests in CNL by a share swap for shares in CanArgo. Through this exchange we acquired an additional 10.8% interest in CNL increasing our interest to 75%. This maintains our effective interest in the Norio PSA after Georgian Oil has completed the first stage of the farm-in at approximately 63.7%. The purchase was achieved by issuing 6,000,000 restricted CanArgo shares to the minority interest holders in CNL. Of the interests in CNL, 4% were owned by Provincial Securities Limited, a company to which Mr. Russell Hammond, a non-executive director of CanArgo, is a financial advisor. Provincial Securities Limited received 2,273,523 shares of common stock in return for their interest. In the event that Georgian Oil exercises the Option and pays the required $6,500,000 to CNL we would be obligated to issue a further 3,000,000 restricted shares to the minority interest holders.
     On September 30, 2004 we announced that we had increased our interest in CNL, by buying out the remaining minority shareholder in that company, NPET Oil Limited. CNL will now become a wholly owned subsidiary of CanArgo. Following completion of the Georgian Oil farm-in to the Norio PSA, CNL will hold an 85% interest in the Norio PSA. CNL also holds 100% of the contractor’s interest in the Block XI(G) and XI(H) Production Sharing Contract (“Tbilisi PSC”). This transaction has therefore increased our interest in the Norio PSA by 21.25%, and by 25% in the Tbilisi PSC. We have issued 6,000,000 restricted shares of our common stock valued at $4,320,000 to NPET Oil Limited in connection with this transaction. Upon recording this transaction, minority interest of $1,351,022 was reduced to $0 and oil and gas properties increased by $2,968,978. At the same time, our commitment under the Norio PSA and the original shareholders’ agreement for a bonus payment of $800,000 to be paid by us to the other shareholders should commercial production be obtained from the Middle Eocene or older strata and a second bonus payment of $800,000 should production exceed 250 tonnes (approximately 1,900 barrels) of oil per day over any 90 day period has terminated.
CanArgo Standard Oil Products Limited
     In September 2002, we approved a plan to sell our interest in CanArgo Standard Oil Products Limited (“CSOP”), a petroleum product retail business in Georgia, to finance our Georgian and Ukrainian development projects. In October 2002, we reached agreement with Westrade Alliance LLC, an unaffiliated company, to sell our wholly owned subsidiary, CanArgo Petroleum Products Limited (“CPPL”), which held our 50% interest in CSOP for $4,000,000 in an arms-length transaction, with legal ownership being transferred upon receipt of final payment due originally in August 2003 and subsequently extended. The final payment of the consideration was received by us in December 2004 at which time we transferred our ownership in CPPL to Westrade Alliance LLC. The results of CSOP’s operations have been presented for financial statement purposes as discontinued operations (See Note 20 — Discontinued Operations).
Georgian American Oil Refinery
     In November 2000, we completed the acquisition of a 51% interest in the Georgian American Oil Refinery (“GAOR”), a company which owns a small refinery located at Sartichala, Georgia. From that date, GAOR became a subsidiary of CanArgo and its results have been included in our consolidated financial statements. However, due to operational difficulties and changes to the fiscal system in Georgia, GAOR ceased to operate during 2001.
     As a result of the uncertainty as to the ultimate recoverability of the carrying value of the refinery, we recorded in 2001 a write-down of the refinery’s property, plant and equipment of approximately $3,500,000. During 2003, a debit balance of $1,274,895 in minority interest was written-off due to a change in the intentions of our minority interest owner and a plan to dispose of the asset. In 2004, we came to an agreement to sell our interest in the refinery. Our interest in the refinery was sold in February 2004.

NOTE 15 — COMMITMENTS AND CONTINGENCIES
     We have contingent obligations and may incur additional obligations, absolute and contingent, with respect to the acquisition and development of oil and gas properties and ventures in which we have interests that require or may require us to expend funds and to issue shares of our Common Stock.
     At December 31, 2005, we had the contingent obligation to issue an aggregate of 187,500 shares of our Common Stock to Fielden Management Services PTY, Ltd (a third party management services company), subject to the satisfaction of conditions related to the achievement of specified performance standards by the Stynawske Field project, an oil field in Ukraine in which we had a previous interest. As far as management is aware, the project is not progressing at the desired pace of development and consequently, in management’s opinion the chance of having to issue these shares is remote.
     Under the Production Sharing Contract for Blocks XI(G) and XI(H) (the “Tbilisi PSC”) in Georgia our subsidiary CanArgo Norio Limited will acquire additional seismic data within three years of the effective date of the contract which is September 29, 2003. The total commitment over the next ten months is $350,000. In the event that no commercial producing wells are developed, our interest in the PSC terminates 10 years from commencement in March 2011.
     In 2002, the Participation Agreement for the three well exploration program on the Ninotsminda/Manavi area with AES Gardabani (a subsidiary of AES Corporation) (“AES”) was terminated without AES earning any rights to any of the Ninotsminda/Manavi area reservoirs. We therefore have no present obligations in respect of AES. However, under a separate Letter of Agreement, if gas from the Sub Middle Eocene is discovered and produced from the exploration area covered by the Participation Agreement, AES will be entitled to recover at the rate of 15% of future gas sales from the Sub Middle Eocene, net of operating costs, approximately $7,500,000, representing their prior funding under the Participation Agreement. AES have now withdrawn from Georgia, but hydrocarbons have been discovered in the Manavi area reservoir and in the event of a successful gas development from the Sub Middle Eocene, it is reasonably possible that AES may exercise their rights under the Letter of Agreement.
     In April 2004, we acquired a 50% interest in the Samgori (Block XI(B)) Production Sharing Contract (“Samgori PSC”) in Georgia. This interest was acquired from Georgian Oil Samgori Limited (“GOSL”), a company wholly owned by Georgian Oil, by one of our subsidiaries, CanArgo Samgori Limited (“CSL”). Under the terms of the agreement dated January 8, 2004, up to 10 horizontal wells will be drilled on the Samgori Field. Completion of well S302, which was funded 100% by us, satisfied our commitment to GOSL under the acquisition agreement. It was planned that the remainder of the drilling program will be funded jointly by CSL and GOSL, the Contractor parties, pro rata to their interest in the Samgori PSC. The total cost to us of participating in the whole program, which was due to be completed by June 2008, was anticipated to be up to $13,500,000.
     Furthermore, under the assignment agreement NPL had agreed outstanding costs and expenses of $37,528,964 in relation to the Samgori PSC which were recoverable by NPL receiving 30% of annual net profit from the Field until such costs had been fully repaid. After NPL’s costs are repaid from either Field production or other production in the PSC (in the event that new fields are developed in areas identified using seismic surveys originally performed by NPL), NPL would continue to receive 5% of annual net profit.
     Under the Samgori PSC, up to 50% of petroleum produced under the contract is allocated to the Contractor parties for the recovery of the cumulative allowable capital, operating and other project costs associated with the Samgori Field and exploration in Block XI(B) (“Cost Recovery Oil”). The cost recovery pool includes the $37,528,964 costs previously incurred by NPL. The balance of production (“Profit Oil”) is allocated on a 50/50 basis between the State and the Contractor parties respectively until capital costs are recovered after which they would receive 30% of Profit Oil. Under the Samgori PSC, Georgian Oil as the State representative in the contract is entitled to receive up to 250,000 tons (approximately 1.6 million barrels) of oil (“Base Level Oil”) from a maximum of 50% per calendar quarter of production when the value of the cumulative Cost Recovery Petroleum, cumulative Profit Oil and cumulative Profit Natural Gas delivered to the Contractor parties exceeds the cumulative allowable capital, operating and other project costs including finance costs associated with the Samgori Field and exploration in Block XI(B) and the NPL costs. While Base Level Oil is being delivered to Georgian Oil, the Contractor parties will continue to be entitled to a maximum of 50% of the remaining Profit Oil. The Base Level Oil is an estimate of the amount of oil that Georgian Oil would have expected to produce from the contract area had the State not come to a contractual arrangement with the previous Contractor party in 1996.
     Upon completion of the acquisition of an interest in the Samgori PSC we had a contractual obligation to issue 4,000,000 shares of CanArgo Common Stock to Europa Oil Services Limited (“Europa”), an unaffiliated company in connection with a consultancy agreement with Europa in relation to this acquisition. On April 16, 2004 Europa was issued with 4,000,000 restricted shares of CanArgo Common Stock in an arms length transaction. A further 12,000,000 shares of CanArgo Common Stock are issuable upon

certain production targets being met from future developments under the Samgori PSC. On March 14, 2006, we signed an agreement with Europa formally terminating the consultancy agreement.
     On February 17, 2006 we issued a press release announcing that our subsidiary, CSL, was not proceeding with further investment in the Samgori PSC and associated farm-in, and accordingly we terminated our interest in the Samgori PSC with effect from February 16, 2006. On termination, we have now been released of all commitments and contingencies that the Company had as at December 31, 2005 in respect of the Samgori PSC.
     In May 2004, NOC entered into a crude oil sales agreement with Primrose Financial Group (“PFG”) to sell its monthly share of oil produced under the Ninotsminda production sharing contract with a total contractual commitment of 84,000 metric tonnes (636,720 bbls) (“Sales Agreement”). As security for payment and having the right to lift up to 8,400 metric tonnes (approximately 64,000 bbls) of oil per month, the buyer caused to be paid to NOC $2,300,000 (“Security Deposit”) to be repaid at the end of the contract period either in money or through the delivery of additional crude oil equal to the value of the security. The Security Deposit replaces the previous security payments totalling $2,300,000 which had been originally made available under previous oil sales agreements.
     On February 4, 2005, NOC and PFG agreed to the terminate the Sales Agreement and enter into a new agreement (“New Agreement”) whereby PFG would receive an immediate repayment of its Security Deposit and obtain an extended term over which it can purchase crude oil produced from the Ninotsminda Field while NOC receives better commercial terms for the sale of its production. The New Agreement has a minimum term of 45 months and contains the following principal terms:
     (i) NOC will make available to PFG NOC’s entire share of production from the Ninotsminda Field including a minimum total amount of 68,555 metric tonnes (the “Minimum Contract Quantity”). In the event NOC fails to produce the Minimum Contract Quantity it will have no liability to PFG;
     (ii) The deliver point shall be at Georgian Oil’s storage reservoirs at Samgori (adjacent to the Ninotsminda Field);
     (iii) The price for the oil will be in US Dollars per net US Barrel equal to the average of the mean of three quotations in Platts Crude Oil Marketwire(C) for Brent Dated Quotations minus a discount: ranging for sales (a) up to the Minimum Contract Quantity from $6.00 to $7.50 based on Brent prices per barrel ranging from less than $15.00 to greater than $25.01, respectively; and (b) for sales of oil in excess of the Minimum Contract Quantity at the commercial discount in Georgia for oil of similar quality less $0.10 per barrel with the maximum discount being $6.00 per barrel for export sales and $5.50 per barrel for local sales; and
     (iv) PFG will pay NOC for the monthly quantity of oil in advance of delivery.
     NOC’s obligations are subject to customary Force Majeure provisions, title and risk of loss pass to buyer at the delivery point, NOC agrees to assist the buyer to sell the oil locally or export oil in accordance with applicable law and the Agreement is governed by English law.
     In September 2004, a blow-out occurred at the N100 well on the Ninotsminda Field. The Company currently estimates that the total costs attributable to the blow-out, including compensation and cleaning of the environment will be $2,000,000. The Company’s insurance policies cover 80% of these costs up to a maximum of $2,500,000 and the remaining 20% insurance retention being payable by the Company. On June 3, 2005 we received $800,000, as a first instalment, from our insurance company and the chance of receiving the remaining amount of up to 80% of our total costs is deemed probable.
     On July 27, 2005, GBOC Ninotsminda, an indirect subsidiary of the Company, received a claim raised by certain of the Ninotsminda villagers (listed on pages 1 to 76 of the claim) in the Tbilisi Regional Court in respect of damage caused by the blowout of the N100 well on the Nintosminda Field in Georgia on September 11, 2004. An additional claim was received in December 2005 thus bringing the relief sought pursuant to both claim to the sum of 32.4 million GEL (approximately $19.0 million at the exchange rate of GEL to US dollars in effect on December 31, 2005). We believe that we have meritorious defenses to this claim and intend to defend it vigorously and as a result of discussions with our legal advisors in Georgia, we would consider the chances of the claim being successful to be remote.
     On September 12, 2005, WEUS Holding Inc (“WEUS”) a subsidiary of Weatherford International Ltd lodged a formal Request for Arbitration with the London Court of International Arbitration against CanArgo Energy Corporation in respect of unpaid invoices for work performed under the Master Service Contract dated June 1, 2004 between the Company and WEUS for the supply of under-balanced coil tubing drilling equipment and services during the first and second quarter of 2005. Pursuant to the Request for

Arbitration, WEUS’ demand for relief is $4,931,332.55. Although the Company has recorded all amounts billed by Weatherford as of December 31, 2005 (see Note 13) the Company is contesting the claim and intends to file a counterclaim. We believe that we have meritorious defenses to this claim and intend to defend it vigorously. At this point in the proceedings it is not possible to predict the outcome of the arbitration. However, in the event that Weatherford is successful, the extent of the loss to the Company would be limited to payment of Weatherford’s professional fess in regards to this matter.
     The Company has been named in with a group of defendants by former interest holders of the Lelyakov oil field in the Ukraine. The plaintiffs are seeking damages of approx 600,000 CDN (approx $514,000 at December 31, 2005 exchange rates) The former owners of UK-Ran Oil Company disposed of their investment in the field prior to selling the Company to CanArgo. CanArgo believes the claim against it to be meritless. The Company is unable at this time to determine a potential outcome but in general would consider the chances of the claim being successful to be remote.
     Under the Ninotsminda PSC, Ninotsminda Oil Company Ltd is required to relinquish at least half of the area then covered by the production sharing contract, but not in portions being actively developed, at five year intervals commencing December 1999. In 1998, these terms were amended with the initial relinquishment being due in 2006 and a reduction in the area to be relinquished at each interval from 50% to 25% whereby the Contractor selects the relinquishment portions.
     CanArgo Norio Limited currently owns a 100% interest in the Norio (Block XI(C)) and North Kumisi Production Sharing Agreement (“Norio PSA”), although this interest has a 25 year term it may be reduced to 85% should the state oil company, Georgian Oil, exercise an option available to it under the PSA for a limited period following the submission of a field development plan. Although we are not able to speak for Georgian Oil, in management’s opinion it is likely that Georgian Oil would exercise the option available to it in the event of a commercial oil or gas discovery. As a contractor party, Georgian Oil would be liable for all costs and expenses in relation to any interest it may acquire in the PSA. This PSA covers an area of approximately 381,034 acres (1,542 km (2)), however, it is subject to a 25% relinquishment every 5 years, commencing in March 2006 whereby the Contractor selects the relinquishment portions.
     Our 2004 Long-Term Stock Incentive Plan (“2004 Plan”) allows for up to 7,500,000 shares of the Company’s common stock to be issued to officers, directors, employees, consultants and advisors pursuant to the grant of stock based awards, including qualified and non-qualified stock, options, restricted stock, stock appreciation rights and other stock based performance awards. Stock options may be exercised, in whole or in part, by giving written notice of exercise to the Corporation specifying the number of shares to be purchased. However, in the event of a Change of Control (as defined in the 2004 Plan) an optionee (other than an optionee who initiated a Change of Control in a capacity other than as an officer or director of the Corporation) may elect to surrender all or part of the stock option to the Corporation and to receive in cash an amount equal to the amount by which the fair market value per share of the Stock on the date of exercise shall exceed the purchase price per share under the stock option multiplied by the number of shares of the Stock granted under the stock option as to which the right granted by this proviso shall have been exercised. In management’s opinion, a Change of Control event (as defined in the 2004 Plan) at this moment in time, is deemed to be remote,. As of December 31, 2005, options to acquire an aggregate of 1,454,000 shares of common stock had been granted under this Plan and were outstanding, 1,214,000 of which are currently vested.
     Lease Commitments — We lease office space under non-cancelable operating lease agreements. Rental expense for the years ended December 31, 2005, 2004 and 2003 was $456,908, $379,102, and $395,355 respectively.

NOTE 16 — OPTIONS WITH REDEMPTION FEATURES
     Our 2004 Plan allows for up to 7,500,000 shares of the Company’s common stock to be issued to officers, directors, employees, consultants and advisors pursuant to the grant of stock based awards, including qualified and non-qualified stock, options, restricted stock, stock appreciation rights and other stock based performance awards. Stock options may be exercised, in whole or in part, by giving written notice of exercise to the Corporation specifying the number of shares to be purchased. However, in the event of Change of Control (as defined in the 2004 Plan) an optionee (other than an optionee who initiated a Change of Control in a capacity other than as an officer or director of the Corporation) may elect to surrender all or part of the stock option to the Corporation and to receive in cash an amount equal to the amount by which the fair market value per share of the Stock on the date of exercise shall exceed the purchase price per share under the stock option multiplied by the number of shares of the Stock granted under the stock option as to which the right granted by this proviso shall have been exercised.
     Under SEC Accounting Series Release 268 — Presentation in Financial Statements of “Redeemable Preferred Stocks”, the Company has calculated and classified the intrinsic value of $2,119,530 as at December 31, 2005 and $723,280 as at December 31, 2004 to options with redemption features, the vested portion of issued share options from our 1995 Long-Term Incentive Plan in accordance with the related guidance.
NOTE 17 — STOCKHOLDERS’ EQUITY
     On July 8, 1998, at a Special Meeting of Stockholders, the stockholders of CanArgo approved the acquisition of all of the common stock of CanArgo Oil and Gas (“CAOG”) for Common Stock of the Company pursuant to the terms of an Amended and Restated Combination Agreement between those two companies (the “Combination Agreement”). Upon completion of the acquisition on July 15, 1998, CAOG became a subsidiary of CanArgo, and each previously outstanding share of CAOG common stock was converted into the right to receive 0.8 shares (the “Exchangeable Shares”) of CAOG which are exchangeable generally at the option of the holders for shares of CanArgo’s Common Stock on a share-for-share basis.
     On January 24, 2002 we announced that we had established May 24, 2002 as the redemption date for all of the Exchangeable Shares of CAOG since the number of outstanding Exchangeable Shares had fallen below the minimum 853,071 share threshold. Each Exchangeable Share was purchased by CanArgo for shares of CanArgo Common Stock on a share-for-share basis resulting in the issuance of an aggregate of 148,826 shares of Common Stock. No cash consideration was issued by CanArgo and the purchase did not increase the total number of shares of Common Stock of CanArgo deemed issued and issuable.
     In February 2004, we announced that we had signed a Standby Equity Distribution Agreement that allowed us, at our option, to issue shares to US-based investment fund Cornell Capital Partners LP up to a maximum value of $20,000,000 over a period of up to two years from the date on which the Registration Statement on Form S-3 registering for resale the shares under the Securities Act of 1933, as amended (“Securities Act”) is declared effective. The Registration Statement was declared effective by the SEC on February 3, 2005
     The total number of shares of common stock authorized was 300,000,000 as of December 31, 2005 and 2004 and 150,000,000 for 2003.
     As of December 31, 2005 and 2004, we had 5,000,000 shares of $0.10 par value preferred stock authorized, of which none were outstanding. The Board of Directors may at any time issue additional shares of preferred stock and may designate the rights and privileges of a series of preferred stock without any prior approval by the stockholders.
     During the years ended December 31, 2005, 2004 and 2003, the following transactions regarding CanArgo’s Common Stock were consummated pursuant to authorization by CanArgo’s Board of Directors or duly constituted committees thereof.

NOTE 18 — NET LOSS PER COMMON SHARE
     Earnings (loss) per share is calculated in accordance with SFAS No. 128, “Earnings Per Share.” Basic and diluted earnings per share are provided for continuing operations, discontinued operations, cumulative effect of change of accounting principle and net income (loss). Basic earnings (loss) per share is computed based upon the weighted average number of shares of common stock outstanding for the period and excludes any potential dilution. Diluted earnings per share reflects potential dilution from the exercise of securities (warrants, options and convertible debt) into common stock. Outstanding options and warrants to purchase common stock are not included in the computation of diluted loss per share because the effect of these instruments would be anti-dilutive for the loss periods presented.
     Basic and diluted net loss per common share for the years ended December 31, 2005, 2004 and 2003 were based on the weighted average number of common shares outstanding during those periods. Options and warrants to purchase CanArgo’s Common Stock were outstanding during the years ended December 31, 2005, 2004 and 2003 but were not included in the computation of diluted net loss per common share because the effect of such inclusion would have been anti-dilutive. The total number of such shares excluded from diluted net loss per common share were 41,644,516, 14,834,080 and 7,986,167 for each of the years ended December 31, 2005, 2004 and 2003 respectively (See Notes 14 and 24).
NOTE 19 — INCOME TAXES
     CanArgo and its U.S. domestic subsidiaries file a U.S. consolidated income tax return. No benefit for U.S. income taxes has been recorded in these consolidated financial statements because of CanArgo’s inability to recognize deferred tax assets under provisions of SFAS 109. Due to the implementation of the quasi-reorganization as of October 31, 1988, future reductions of the valuation allowance relating to those deferred tax assets existing at the date of the quasi-reorganization, if any, will be allocated to capital in excess of par value.
     A reconciliation of the differences between income taxes computed at the U.S. federal statutory rate of 34% and CanArgo’s reported provision for income taxes is as follows:

     On August 1, 1991, August 17, 1994, July 15, 1998 and June 28, 2000, CanArgo experienced changes in ownership as defined in Section 382 of the Internal Revenue Code (“IRC”). The effect of these changes in ownership is to limit the utilization of certain existing net operating loss carryforwards for income tax purposes to approximately $2,920,000 per year on a cumulative basis. As of December 31, 2005, total unexpired U.S. net operating loss carryforwards were approximately $38,242,378. Of that amount, approximately $15,375,000 was incurred prior to the ownership change in 2000 and is subject to the IRC Section 382 limitation (See Note 2).
     The U.S. net operating loss carryforwards expire from 2006 to 2025. CanArgo also has approximately $8,709,000 of foreign net operating loss carryforwards. A significant portion of the foreign net operating loss carryforwards may be subject to limitations similar to IRC Section 382.
     CanArgo’s available net operating loss carryforwards may be used to offset future taxable income, if any, prior to their expiration. CanArgo may experience further limitations on the utilization of net operating loss carryforwards and other tax benefits as a result of additional changes in ownership.
NOTE 20 — DISCONTINUED OPERATIONS
CanArgo Standard Oil Products
     In September 2002, we approved a plan to sell our interest in CanArgo Standard Oil Products Limited (“CSOP”), a petroleum product retail business in Georgia, to finance our Georgian and Ukrainian development projects. In October 2002, we reached agreement with Westrade Alliance LLC, an unaffiliated company, to sell our wholly owned subsidiary, CanArgo Petroleum Products Limited (“CPPL”), which held our 50% interest in CSOP for $4,000,000 in an arms-length transaction, with legal ownership being transferred upon receipt of final payment due originally in August 2003 and subsequently extended. The total payment received in 2004 was $1,857,000 with the final payment of the consideration received by us in December 2004 at which time we transferred our ownership in CPPL to Westrade Alliance LLC. The gain recorded on disposition of subsidiary was $1,275,351.
     The results of discontinued operations in respect of CSOP consisted of the following for the years ending December 31:

Lateral Vector Resources Inc
     Lateral Vector Resources Inc. (“LVR”), a wholly-owned subsidiary of CanArgo acquired by us in July 2001, negotiated and concluded with Ukrnafta, the Ukrainian State Oil Company, a Joint Investment Production Activity (“JIPA”) agreement in 1998 to develop the Bugruvativske Field located in Eastern Ukraine.
     In 2003, due to the lack of progress with the implementation of the JIPA, and failure to reach a negotiated agreement with Ukrnafta, management reached the decision to dispose of its interest in the Bugruvativske project and withdraw from Ukraine. In negotiations with possible buyers in 2003 the Company believed the realizable value to be approximately $250.000. Consequently, we recorded in 2003 a write-down in respect to the LVR deal and the acquisition of the Bugruvativske Field of approximately $4,790,727, which reduced the carrying value of LVR to $250,000 as of December 31, 2003. No gain or loss was recorded in 2004 upon the sale of LVR.
     On May 28, 2004, we announced that pursuant to a signed agreement between CanArgo Acquisition Corporation, our wholly owned subsidiary, and Stanhope Solutions Ltd., we had completed a transaction to sell our interest in the Bugruvativske Field through the disposal of LVR for $2,000,000. We received $250,000 as an initial payment and will receive the remaining $1,750,000 based upon certain production targets being achieved on the project. As of March 14, 2005, we had not received any further payments nor does management expect to receive any further payment.

Georgian American Oil Refinery
     In 2003, we approved a plan to dispose of our interest in the Georgian American Oil Refinery Limited (“GAOR”) as the refinery had remained closed since 2001 and neither we nor our partners could find a commercially viable option to putting the refinery back into operation. In February 2004, we reached an agreement with a local Georgian company to sell our 51% interest in GAOR for a nominal price of one US dollar and the buyers assumption of all the obligations and debts of GAOR to the State of Georgia including deferred tax liabilities of approximately $380,000. The gain recorded on disposition of GAOR was $330,923. In 2003, we announced publicly that we were re-evaluating our treatment in our 2001 and 2002 financial statements of our minority interest in GAOR. After reviewing the basis for our accounting for our interest in GAOR and after discussions with our former auditors we have concluded that our interest was properly accounted for in those statements.
     The results of operations of GAOR have been classified as discontinued for all periods presented. The minority interest related to GAOR has not been reclassified for any of the periods presented, however net income from discontinued operations is disclosed net of taxes and minority interest. During 2003, a debit balance of $1,274,895 in minority interest was written-off due to a change in the intentions of our minority interest owner and a plan to dispose of the asset. The plan to dispose of the asset also led to the write-off of an inter-company payable relating to oil sales purchased from Ninotsminda Oil Company Limited. These items have been respectively recorded in impairment of other assets and other income (expense) components of continuing operations.

3-megawatt duel fuel power generator
     In 2003, we signed a sales agreement disposing of a 3-megawatt duel fuel power generator for $600,000 and have received a non-refundable deposit of approximately $300,000. The unit was shipped to the United States where it underwent tests in late 2004. On completion of these tests to the satisfaction of the buyer, we were to transfer title for this equipment and receive the final payment of $300,000. Although the unit was successfully tested, the buyer failed to meet the sale contract terms resulting in the loss of its deposit in the third quarter, 2005. We are currently remarketing the generator.
     The generator has been classified as “Assets held for sale” for all periods presented. The generator was impaired in 2003 by $80,000 to reflect its fair value less cost to sell. The Company believes that the fair value established in 2003 is still valid. The Company’s marketing efforts include a sales price less expected costs of any future sale to be in line with the fair value established in 2003.

     On June 7, 2005, CanArgo made an offer to acquire 55% of the ordinary share capital of Tethys which was held by Provincial and Vando for consideration of 11,000,000 CanArgo common shares. On June 9, 2005 CanArgo issued 5,500,000 shares to Provincial, of which Russell Hammond (one of our non-executive directors) is Investment Advisor in connection with this transaction.
     Mr. Russell Hammond, a non-executive director of CanArgo, is also an Investment Advisor to Provincial Securities Limited who became a minority shareholder in the Norio and North Kumisi Production Sharing Agreement through a farm-in agreement to the Norio MK72 well. On September 4, 2003 we concluded a deal to purchase Provincial Securities Limited’s minority interest in CanArgo Norio Limited by a share swap for shares in CanArgo. Provincial Securities Limited received 2,234,719 shares of CanArgo common stock in relation to the transaction (see Note 14). Provincial Securities Limited also had an interest in Tethys Petroleum Investments Limited which was sold in June 2005 to us by a share exchange for shares in CanArgo. Provincial Securities Limited received 5,500,000 shares of CanArgo common stock in relation to the transaction, Transactions with affiliates or other related parties including management of affiliates are to be undertaken on the same basis as third party arms-length transactions.
     Transactions with affiliates are reviewed and voted on solely by non-interested members of the board of directors.
NOTE 25 — SUBSEQUENT EVENTS
Loan with Detachable Warrants
     On February 14, 2006 we exercised the option forcing conversion of the loan from Salahi Ozturk advanced pursuant to the amended and restated loan and warrant agreement dated August 27, 2004 (“Amended Agreement”) into 1,521,739 shares of our common stock.
Samgori PSC
     On February 17, 2006 we issued a press release announcing that our subsidiary, CanArgo Samgori Limited (“CSL”), was not proceeding with further investment in the Samgori PSC and associated farm-in, and accordingly we terminated our interest in the Samgori PSC with effect from February 16, 2006. The decision by CSL not to proceed with further investment under the current farm-in arrangements was due to the inability of CSL’s partner in the project, Georgian Oil Samgori Ltd, to provide its share of funding to further the development of the Field. We consider that there would have been insufficient time to meet the commitments under the Agreement with NPL and we were not prepared to fund the project, which is not without risk, on a 100% basis without different commercial terms and an extension to the commitment period. It was not possible to negotiate a satisfactory position on either matter. CSL has been informed that, given this, NPL have indicated that they now intend to exercise their right to take back 100% of the Contractor Share in the Samgori PSC from GOSL and, accordingly, effective February 16, 2006 we have withdrawn from the Samgori PSC. CSL had been sharing in both costs and revenues from ongoing production since April 2004, and had approximately broken-even on a cash basis on the project. In 2005 the Samgori PSC added approximately $0.8 million in net revenues to CanArgo. Since 2004, we have capitalized costs of approximately $1.25 million in relation to the Samgori PSC which are part of our cost pool which will be amortized and depleted in accordance with CanArgo’s usual accounting policies for oil and gas properties.
Financing
     On March 3, 2006, we announced that we had entered into a $13,000,000 private placement with a small group of accredited investors (“Note holders”) of senior subordinated convertible guaranteed notes (the “Subordinated Notes”) and two year warrants to purchase an aggregate of 13,000,000 shares of common stock (“Warrants”).
     The Subordinated Notes are convertible in whole or in part into CanArgo common stock at a price of $1.37 per share, subject to certain anti-dilution adjustments, and will mature on September 1, 2009. Subject to the consent of the Senior Secured Note holders, CanArgo may call the Subordinated Notes from March 1, 2007 at an initial price of 105% of par, declining 1% every six months. Interest will be payable in cash at 3% per annum until December 31, 2006, 10% per annum thereafter. The Subordinated Notes will be subordinated to CanArgo’s existing issue of Senior Secured Notes and guaranteed on a subordinated basis by CanArgo’s material subsidiaries.
     The Subordinated Note holders will have the right (as an alternative) until March 3, 2007 (or until 30 days after receipt of the consent of the Senior Secured Note holders is obtained if such conversion is prevented under the terms of the Senior Secured Notes) to convert their notes into shares of common stock of TPI, with a nominal value of £0.10 per share at a conversion price per share based on a formula determined by dividing the sum of $52 million plus the amount of any unreimbursed amounts advanced by the Company

to TPI by 100,000 in the Subordinated Note holders’ Relevant Percentages (as defined in the Note Purchase Agreement). At the time of any TPI conversion any further advances (in excess of the $13 million) from CanArgo to TPI may be, at CanArgo’s discretion, either repaid, or converted into TPI equity based on a valuation of $52 million [plus the amount of any unreimbursed amounts advanced by the Company to TPI], with the Subordinated Note holders having the ability to maintain their equity position by providing further funding on a pro-rata basis.
     The Warrants will be exercisable in whole or in part for CanArgo common stock at an exercise price of $1.37 per share, subject to adjustment. The expiration date of the Warrants may be accelerated at CanArgo’s option in the event that the Manavi M12 appraisal well in the Georgia (which is currently being drilled) indicates, by way of an independent engineering report, sustainable production potential, if developed, in excess of 7,500 barrels of oil per day.
     The proceeds are required by the agreement to be used to fund the development of the Kyzyloi Gas Field in the Kazakhstan and on the commitment exploration programs in Kazakhstan through TPI, which holds CanArgo’s Kazakhstan assets and therefore these funds will not be available for the Company for general working capital.
     In connection with the offering the Company entered into a registration rights agreement with the note holders and agreed to register the shares of common stock underlying the warrants and the convertible note (in the event that they are converted into shares of the Company’s common stock). The registration rights agreement gives the note holders the right to piggy back or demand registration rights and the Company must use its best efforts to have the registration declared effective within 120 days of any demand by the note holders. In addition, the agreement requires the Company have a registration agreement covering the shares underlying the note and the warrants declared effective no later than December 31, 2006 if not demanded earlier by the note holders. The Company is required under the registration rights agreement to maintain the effectiveness of the registration for a period of the earlier of two years or when the securities are no longer restricted securities. The registration rights agreement does not contain penalty provisions in the event the Company fails to register or maintain an effective registration statement covering the resale of the underlying common stock. The Company is only required to register for resale shares of its common stock, and does not have to register shares of its wholly owned subsidiary, TPI, in the event that the note holders elect to convert into shares of TPI as defined in the agreeemnt.
     On March 14, 2006, we entered into an agreement (“Termination Agreement”) with Europa Oil Services Limited (“Europa”), an unaffiliated company, formally terminating the consultancy agreement between CanArgo and Europa dated January 8, 2004. Under the terms of the consultancy agreement, CanArgo had an outstanding obligation to issue up to 12 million shares of CanArgo common stock to Europa upon certain production targets being met from future developments under the Samgori PSC. With effect from February 16, 2006, we have withdrawn from the Samgori PSC. Pursuant to the terms of the Termination Agreement the parties accordingly agreed that the consultancy agreement had terminated with effect from February 16, 2006. CanArgo has not incurred any material early termination penalties as a result of the termination of the consultancy agreement.

NOTE 26 — SUPPLEMENTAL OIL AND GAS DISCLOSURE (Unaudited)
ESTIMATED NET QUANTITIES OF OIL AND GAS RESERVES
     Users of this information should be aware that the process of estimating quantities of “proved” and “proved developed” natural gas and crude oil reserves is very complex, requiring significant subjective decisions in the evaluation of all available geological, engineering and economic data for each reservoir. The data for a given reservoir may also change substantially over time as a result of numerous factors including, but not limited to, additional development activity, evolving production history and continual reassessment of the viability of production under varying economic conditions. Consequently, material revisions to existing reserve estimates occur from time to time. Although every reasonable effort is made to ensure that reserve estimates reported represent the most accurate assessments possible, the significance of the subjective decisions required and variances in available data for various reservoirs make these estimates generally less precise than other estimates presented in connection with financial statement disclosures.
     Proved reserves are estimated quantities of natural gas, crude oil and condensate that geological and engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs with existing equipment under existing economic and operating conditions.
     Proved developed reserves are proved reserves that can be expected to be recovered through existing wells with existing equipment and under existing economic and operating conditions.
     No major discovery or other favorable or adverse event subsequent to December 31, 2004 is believed to have caused a material change in the estimates of proved or proved developed reserves as of that date.
Oil and gas reserves
     The following tables set forth our net proved oil and gas reserves, including the changes therein, and net proved developed reserves at December 31, 2005, as estimated by the independent petroleum engineering firm, Oilfield Production Consultants Limited for Georgia:

(1)   PSC Entitlement Volumes attributed to CanArgo are calculated using the “economic interest method” applied to the terms of the production sharing contract. PSC Entitlement Volumes are those produced volumes which, through the production sharing contract, accrue to the benefit of Ninotsminda Oil Company after deduction of Georgian Oil’s share which includes all Georgian taxes, levies and duties. As a result of CanArgo’s interest in Ninotsminda Oil Company, these volumes accrue to the benefit of CanArgo for the recovery of capital, repayment of operating costs and share of profit.

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL AND GAS RESERVES
     The following information has been developed utilizing procedures prescribed by SFAS No. 69 Disclosure about Oil and Gas Producing Activities (“SFAS 69”) and based on crude oil reserve and production volumes estimated by the Company’s engineering staff. It may be useful for certain comparative purposes, but should not be solely relied upon in evaluating the Company or its performance. Further, information contained in the following table should not be considered as representative of realistic assessments of future cash flows, nor should the Standardized Measure of Discounted Future Net Cash Flows be viewed as representative of the current value of the Company.
     CanArgo believes that the following factors should be taken into account in reviewing the following information: (1) future costs and selling prices will probably differ from those required to be used in these calculations; (2) actual rates of production achieved in future years may vary significantly from the rate of production assumed in the calculations; (3) selection of a 10% discount rate is arbitrary and may not be reasonable as a measure of the relative risk inherent in realizing future net oil and gas revenues; and (4) future net revenues may be subject to different rates of income taxation.
     Under the Standardized Measure, future cash inflows were estimated by applying period-end oil prices adjusted for fixed and determinable escalations to the estimated future production of period-end proven reserves. Future cash inflows were reduced by estimated future development, abandonment and production costs based on period-end costs in order to arrive at net cash flow before tax. Future income tax expenses has been computed by applying period-end statutory tax rates to aggregate future pre-tax net cash flows, reduced by the tax basis of the properties involved and tax carryforwards. Use of a 10% discount rate is required by SFAS No. 69.
     Management does not rely solely upon the following information in making investment and operating decisions. Such decisions are based upon a wide range of factors, including estimates of probable as well as proven reserves and varying price and cost assumptions considered more representative of a range of possible economic conditions that may be anticipated.
Standardized measure of discounted future net cash flows relating to proved oil and gas reserves
     The standardized measure of discounted future net cash flows relating to proved oil and gas reserves is as follows:

(1)   In Georgia, future cash flows are based on PSC Entitlement Volumes attributed to CanArgo using the “economic interest method” applied to the terms of the production sharing contract. PSC Entitlement Volumes are those produced volumes which, through the production sharing contract, accrue to the benefit of Ninotsminda Oil Company Limited after deduction of Georgian Oil’s share which includes all Georgian taxes, levies and duties. As a result of our interest in Ninotsminda Oil Company Limited, these volumes accrue to the benefit of CanArgo for the recovery of capital, repayment of operating costs and share of profit. In Kazakhstan, Tethys Petroleum Investment Limited (TPI) through its 100% owned Kazakhstan subsidiary TKL (Tethys Kazakhstan Limited), holds 70% ownership rights in BN Munai LLP, a Kazakh registered company that has the 100% rights to the Kyzyloi field. Under a loan agreement with BN Munai LLP, TKL will take 100% of the net cash flow of the Kyzyloi development until its loan is repaid. This loan is currently in excess of net cash flows generated from the production of gross proven reserves.
 
(2)   On June 9, 2005 we acquired 100% ownership of Tethys Petroleum Investments Limited (TPI) and as at December 31, 2005 this entity is now consolidated in our financial statements. TPI through its 100% owned Kazakhstan subsidiary TKL (Tethys Kazakhstan Limited), holds 70% ownership rights in BN Munai LLP, a Kazakh registered company that has the 100% rights to the Kyzyloi field. Prior to 100% ownership, we chose to use our equity ownership percentage as the basis for recording our portion of our investees’ loss.

(1)   Other changes include a reduction in our cash flows resulting from a change in our oil entitlement as goverened by the Ninotsminda PSC primarily due to increased oil prices used in the standardized measure of discounted future net cash flow for 2005.
