12% Subordinated Convertible Guaranteed Notes due June 28, 2010

June 28, 2006

TO EACH OF THE PURCHASERS LISTED IN
THE ATTACHED SCHEDULE A:

Ladies and Gentlemen:

CanArgo Energy Corporation, a Delaware corporation (the “Company”), agrees with Persistency, a company incorporated in the Cayman Islands (“you” or the “Purchaser” or “Persistency” and together with any other Purchasers listed in the attached Schedule A collectively referred to herein as the “Purchasers", and including and referring to any and all subsequent holders of the Notes) as follows:

SECTION 1. AUTHORIZATION OF NOTES AND WARRANTS.

The Company will authorize the issue and sale of: (i) US$10,000,000 aggregate principal amount, of its 12% Subordinated Convertible Guaranteed Notes due June 28, 2010 (the “Notes”, such term to include any such notes issued in substitution therefore pursuant to Section 15 of this Agreement) and (ii) warrants to purchase up to 12.5 million shares at an exercise price of $1 per share, subject to adjustment, of the Company’s common stock, par value $.10 per share, expiring on the second anniversary of the Closing Date, subject to acceleration under certain circumstances (the “Warrants”). The Notes shall be substantially in the form set out in Exhibit 1, with such changes thereto, if any, as may be approved by you, the Required Holders and the Company. The Warrants purchased by Persistency pursuant to this Agreement shall be substantially in the form set out in Exhibit 2, with such changes thereto, if any, as may be approved by you and the Company. Certain capitalized terms used in this Agreement are defined in Schedule B; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

SECTION 2. SALE AND PURCHASE OF NOTES AND WARRANTS.

Subject to the terms and conditions of this Agreement, the Company will issue and sell to you and you will purchase from the Company, at the Closing provided for in Section 3, Notes and Warrants in the principal and share amounts specified opposite your name in Schedule A at the purchase price of 100% of the principal amount of the Notes (the “Purchase Price”).

SECTION 3. SECURITY.

Section 3.1 Guaranty. As security for all its obligations to the Purchasers under this Agreement and the other Loan Documents, the Subsidiary Guarantors shall each absolutely, unconditionally and irrevocably, jointly and severally guarantee to each holder of the Notes and its successors and assigns, the full and punctual payment and performance when due, whether at stated maturity, by acceleration or otherwise, of the principal at the applicable Redemption Price and interest on (including, without limitation, interest, whether or not an allowable claim, accruing after the date of filing of any petition in bankruptcy, or the commencement of any bankruptcy, insolvency or similar proceeding relating to the Company) the Notes and all other amounts under the Note Purchase Agreement and all other obligations, agreements and covenants of the Company now or hereafter existing under the Notes, the Note Purchase Agreement or any of the other Loan Documents, subject to the prior right of the holders of the Senior Indebtedness to the full and punctual payment and performance when due of the Company’s indebtedness and obligations evidenced thereby as provided in Section 4 hereof.

SECTION 4. SUBORDINATION

Section 4.1 Payment Subordinated. Anything in this Agreement or the Notes notwithstanding, the payment of the Subordinated Indebtedness is and shall be expressly subordinate and junior in right of payment and, as provided in Section 4.4 hereof, any exercise of remedies, to the prior payment or conversion in full of the Senior Indebtedness to the extent and in the manner provided herein, and the Subordinated Indebtedness is hereby subordinated as a claim against the Company or any of the assets of the Company whether such claim be (i) in the event of any distribution of the assets of the Company, upon any voluntary or involuntary dissolution, winding-up, total or partial liquidation or reorganization, or bankruptcy, insolvency, receivership or other statutory or common law proceedings or arrangements involving the Company or the readjustment of any of its liabilities or any assignment for the benefit of creditors or any marshaling of its assets or liabilities (collectively called a “Reorganization”), or (ii) other than in connection with a Reorganization, to the prior payment or conversion in full of the Senior Indebtedness. In furtherance of the foregoing, the Company agrees that it will not make, and the holder of Subordinated Indebtedness agrees that it will not accept or receive, any payment of Subordinated Indebtedness, including, without limitation, any payment received through the exercise of any right of setoff, counterclaim or cross claim, until all of the Senior Indebtedness has been paid or satisfied in full or provision made for the full payment thereof in cash or the satisfaction thereof in full, except to the extent such payment is permitted by Section 12.6 hereof.

Section 4.2 Distributions in Reorganization.

(a) In the event of any Reorganization relative to the Company or any of its properties, then all of the Senior Indebtedness shall first be paid in full in cash before any payment is made in respect of the Subordinated Indebtedness, and in any such proceedings any payment or distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in respect of the Subordinated Indebtedness shall be paid or delivered directly to the Agent for application in payment of the Senior Indebtedness, unless and until all such Senior Indebtedness shall have been paid or satisfied in full, and each holder of

Subordinated Indebtedness does hereby authorize the Agent to accept and receive for any payment or distribution and to apply such payment or distribution to the payment of the then unpaid Senior Indebtedness, and to do any and all things and to execute all instruments necessary to effectuate the foregoing. In the event that, upon any such Reorganization, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, shall be received by any holder of Subordinated Indebtedness before all Senior Indebtedness is paid or satisfied in full, such payment or distribution shall be immediately paid over to the Agent for application to the payment of all Senior Indebtedness remaining unpaid until all such Senior Indebtedness shall have been paid or satisfied in full, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness. Notwithstanding the foregoing provisions of this Section 4.2, in the event that a plan is proposed in the course of a bankruptcy proceeding in a United States Bankruptcy Court or any other court of competent jurisdiction (a “Bankruptcy Plan”) and the Agent consents thereto in writing, any holder of Subordinated Indebtedness shall be entitled to retain any cash, securities or other property payable to it in accordance with the terms of such Bankruptcy Plan.

(b) If the Purchasers fail to file a claim in any Reorganization at least 45 calendar days prior to the date established by the rule of law or order of court for such filing, the Purchasers do hereby authorize the Agent to prove such claim in such proceedings on the Subordinated Indebtedness.

Section 4.3 Effect of Provisions. The provisions hereof are solely for the purpose of defining the relative rights of the holders of Senior Indebtedness on the one hand, and the holders of Subordinated Indebtedness on the other hand, and none of such provisions shall impair, as between the Company and any holder of the Subordinated Indebtedness, the obligations of the Company which are unconditional and absolute, to pay to such holder all of the Subordinated Indebtedness in accordance with the terms thereof nor, except as provided in Section 4.4 below, shall any such provisions prevent any holder of Subordinated Indebtedness from exercising all remedies otherwise permitted by applicable law or under the terms of such Subordinated Indebtedness upon a default thereunder, subject to the rights, if any, of holders of Senior Indebtedness under the provisions of this Agreement.

Section 4.4 Limit on Right of Action.

(a) Each Purchaser, for itself and its successors and assigns, agrees for the benefit of the holders of the Senior Indebtedness that so long as any part of the Senior Indebtedness remains outstanding, the Purchaser will not take any action to accelerate or demand the payment of the Subordinated Indebtedness or to foreclose or otherwise realize on any security or guaranty given by the Company, any Subsidiary Guarantor or any of their Affiliates to secure or guarantee the Subordinated Indebtedness prior to the earlier of (i) a Reorganization or (ii) the acceleration of the Senior Indebtedness by the holders thereof; provided, that, the prohibition contained in this sentence shall not be applicable during any period which does not constitute a Blockage Period (as hereinafter defined); provided, further, that the Purchaser, for itself and its successors and assigns shall be permitted to take any such action only following the passage of 30 days after the Agent has received written notice of the intention of the Purchaser, for itself and its successors and assigns to take any such action and setting forth a description of the

action proposed to be taken, which notice may be delivered only at such time as a default shall have occurred and be continuing with respect to the Subordinated Indebtedness. The foregoing provisions of this Section 4.4 are solely for the purpose of defining the relative rights of the holders of Senior Indebtedness on the one hand and the holders of the Subordinated Indebtedness on the other hand and shall not limit or otherwise affect any rights which the holders of the Subordinated Indebtedness may have against the Company under the terms of this Agreement or the Notes. Each Purchaser, for itself and its successors and assigns agrees that it will not take any action that will impede, interfere with or restrict or restrain the exercise by the holders of the Senior Indebtedness of their rights and remedies under either the Senior Secured Notes or the Subordinated Notes (including, without limitation, the right to apply for and have a receiver appointed thereunder for the assets or stock of any CanArgo Group Member) and, upon commencement of any Reorganization, will take such actions as may be reasonably necessary or appropriate to effectuate the obligations of the Purchasers pursuant to this Agreement.

(b) If an Event of Default other than a Payment Default shall have occurred, no payment on the Subordinated Indebtedness shall be made for a period (a “Blockage Period”) of time commencing upon delivery by the Agent to the Company and by the Company to the Purchasers of written notice specifying the Event of Default (the “Blockage Notice”) and continuing until the earlier of (A) 270 days from the date of delivery of the Blockage Notice or (B) the date on which all such Events of Default described in such Blockage Notice have been cured or waived; provided, that, if such Event of Default is waived by the Agent or is cured and any other Event of Default occurs or shall have occurred then no payments shall be permitted under the foregoing provisions of this paragraph (ii) until the expiration of 270 days after receipt by the Purchasers of written notice from the Company of such other Event of Default (or until the cure or waiver thereof by the Agent if such cure or waiver thereof occurs during such 270 day period)

Section 4.5 Right to Amend, etc. The holders of the Subordinated Indebtedness acknowledge and agree that the holders of the Senior Indebtedness may, in their sole discretion (and without in any way diminishing or altering their rights hereunder or the subordination provisions contained herein), modify, amend, waive or release any of the terms of the Senior Indebtedness or of any other document relative thereto and to exercise or refrain from exercising any powers or rights which they may have thereunder; including, without limitation, the right to increase the amount, extend the maturity, change the payment terms, and to refinance all or any portion of the Senior Indebtedness. The Required Holders may modify, amend, waive or release any of the terms of this Agreement, the Notes, the Subsidiary Guaranty, the Warrants, the Registration Rights Agreement or the Subordinated Indebtedness or any document relative thereto, including, without limitation, to increase the amount, extend the maturity, change any payment terms and to refinance all or any portion of the Subordinated Indebtedness and, subject to the provisions of this Agreement, to exercise or refrain from exercising any powers or rights which they may have thereunder; provided, that, any such modification, amendment, waiver or release shall not be inconsistent with the provisions of this Section 4 or otherwise adversely affect the rights and remedies of the holders of the Senior Indebtedness hereunder. The Required Holders shall promptly notify the Agent of any such modification, amendment, waiver or release. This Agreement, together with the Notes, the Subsidiary Guaranty, the Warrants, the Registration Rights Agreement

and any other documents and agreements related thereto, sets forth the entire understanding of the parties hereto with respect to the subject matter hereof and may not be amended except by an instrument in writing executed and delivered by the parties hereto.

As used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U.

SECTION 8. REPRESENTATIONS OF THE PURCHASER.

Section 8.1. Due Authorization; Absence of Conflicts; Enforceability; Purchase for Investment, etc.

(a) You represent and warrant to Company that you have the full legal capacity, power and authority to execute, deliver and perform the Loan Documents and Warrants to which you are a party; the execution, delivery and performance by you of each Loan Document and Warrant to which you are a party have been duly authorized by all necessary legal action on your part; your execution, delivery and performance of the Loan Documents and Warrants to

which you are a party and the consummation of the transactions contemplated hereby and thereby will not (a) conflict with (i) any provision of any governing instrument applicable to you, or (ii) any Material permit, franchise, judgment, decree, law, rule or regulation applicable to you or your assets, or (b) result in any Material breach of any terms or provisions of, or constitute a Material default under, any Material contract, agreement or instrument to which you are a party or by which you are bound; and such Loan Document and Warrant constitutes a legal, valid and binding obligation enforceable against you in accordance with its terms, except as such enforceability may be limited by (a) applicable bankruptcy, insolvency, reorganization, moratorium, or other similar laws affecting the enforcement of creditors’ rights generally and (b) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(b) You represent and warrant to the Company that you are purchasing the Notes and Warrants and upon their respective conversion and exercise, the shares of Common Stock of the Company, for your own account or for one or more separate accounts maintained by you or for the account of one or more pension or trust funds for investment and not with a view to the distribution thereof or any interest therein, provided that the disposition of your or their property shall at all times be within your or their control and in compliance with applicable Securities Laws. You understand that the Notes and Warrants and except as contemplated by the Registration Rights Agreement, upon their respective conversion and exercise, the Common Stock has not been and will not be registered under any Securities Laws and may be resold only if registered pursuant to the provisions of applicable Securities Laws or if an exemption from such registration is available, except under circumstances where neither such registration nor such an exemption is required by law.

A legend to this effect shall be set forth on the face of each Note and Warrant and absent an effective registration under the Securities Act each certificate evidencing any shares of Common Stock issued upon their respective conversion or exercise.

(d) You have sufficient knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risks of your investment in the Notes and the shares of Common Stock issuable upon

conversion of the Notes or exercise of the Warrants and you are capable of bearing the economic risks of such investment, including a complete loss of your investment.

Section 8.2. Access to Information.

From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest, at the applicable Redemption Price, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be

surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note. In the case of any conversion of Notes pursuant to Section 11.7, the interest on the principal amount of the converted Notes through the date of conversion shall be due and payable on the date of conversion.

Section 10.4. Purchase of Notes. Save with the consent of the Required Holders, the Company will not and will not permit any CanArgo Group Member to directly or indirectly purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes or pursuant to an offer to purchase made to all holders on the same terms and conditions.

SECTION 11. AFFIRMATIVE COVENANTS.

The Company covenants, on its behalf and on behalf of all the other CanArgo Group Members, that so long as at least $1 million in aggregate principal amount of the Notes is outstanding:

Section 11.1. Compliance with Law. The Company will and will cause each of the other CanArgo Group Members to comply with all applicable laws, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, applicable Environmental Laws, in all respects, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case except to the extent that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section 11.2. Insurance. Except for or as a result of the failure by a counterparty to comply with its obligations under a Basic Document, the Company will and will cause each of the other CanArgo Group Members to maintain with insurers which on the date the policy commences are financially sound and reputable, insurance with respect to their respective Material properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated. To the extent a counterparty to a Basic Document fails to comply with its obligations under a Basic Document, the Company shall, or shall cause any Material Subsidiary that is a party to such Basic Document, to use commercially reasonable efforts to enforce the terms of the Basic Document.

Section 11.3. Maintenance of Properties. Except for or as a result of the failure by a counterparty to comply with its obligations under a Basic Document, the Company will and will cause each of the other CanArgo Group Members to maintain and keep, or cause to be maintained and kept, their interests in the respective Properties constituting Material tangible personal property in good repair, working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be conducted in the ordinary course at all times, provided that the Tethys Spin Out shall not constitute a failure to maintain an interest in the respective Properties constituting Material tangible personal property nor shall this Section prevent the Company or any of the other CanArgo Group

Members from discontinuing the operation and the maintenance of any of its Properties if such discontinuance is desirable in the conduct of its business and the Company has concluded that such discontinuance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section 11.4. Payment of Taxes and Claims. The Company will and will cause each of the other CanArgo Group Members to file all tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be properly due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent such taxes and assessments have become properly due and payable and before they have become delinquent, and all claims for which sums have become due and payable that have become a Lien on properties or assets of the Company or any other CanArgo Group Member, provided that neither the Company nor any other CanArgo Group Member need pay any such tax or assessment or claims if (i) the amount, applicability or validity thereof is contested by the Company or such other CanArgo Group Member on a timely basis in good faith and in appropriate proceedings, and the Company or such other CanArgo Group Member has established adequate reserves therefor in accordance with appropriate GAAP on the books of the Company or such other CanArgo Group Member or (ii) the nonpayment of all such taxes and assessments and claims in the aggregate could not reasonably be expected to have a Material Adverse Effect.

Section 11.5. Corporate Existence, etc. The Company will at all times preserve and keep in full force and effect its corporate existence. Subject to Sections 12.2 and 12.8, the Company will at all times preserve and keep in full force and effect the corporate existence of each of the other CanArgo Group Members (unless merged into the Company or a Material Subsidiary) and all rights and franchises of the Company and the other CanArgo Group Members unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise could not, individually or in the aggregate, have a Material Adverse Effect; provided that the foregoing shall not prohibit any merger, consolidation, liquidation or dissolution permitted under Section 12.2.

Section 11.6. Additional Subsidiaries. All Material Subsidiaries of the Company formed or acquired after the date of the Closing shall execute a Subsidiary Guaranty substantially in the form required by the terms of the Subsidiary Guaranty and shall thereafter be deemed to constitute a CanArgo Group Member. Notwithstanding the foregoing, the Parties agree that the following Persons shall not be obliged, pursuant to the requirements of this Section 11.6, to execute and deliver a Subsidiary Guaranty: (i) a Material Subsidiary of the Company in which an equity holder in such Material Subsidiary owns 20% or greater of all Equity Interest in such a Material Subsidiary, (ii) BN Munai LLP, (iii) a Subsidiary of BN Munai LLP, or (iv) a Material Subsidiary that is a Material Subsidiary solely because such Material Subsidiary has Indebtedness outstanding of greater than $2,500,000 to a CanArgo Group Member and the Company, directly or indirectly, owns less than 75% of all of the Equity Interest of such Material Subsidiary.

Section 11.7. Conversion of Note Purchasers shall have the right to convert each of their Notes as follows:

(a) At any time a Purchaser may convert all or, subject to the limitations hereinafter set forth, a portion of the outstanding principal

(an “Optional Conversion”) into shares of Common Stock of the Company at a price per share equal to US$1 per share, as such price may be adjusted pursuant to Section 11.7(e) and 11.7(f) (“Conversion Price”), except that Persistency may not convert any portion of the outstanding principal on the Notes purchased by Persistency pursuant to this Agreement until at least six (6) months from the Closing Date, unless there is a Mandatory Exercise of the Warrants, as defined in the Warrant, in which case any and all of the outstanding Notes held by Persistency shall automatically and simultaneously become immediately convertible at the option of the Purchaser on receipt of the Mandatory Exercise Notice, as defined in the Warrant. Any such Optional Conversions of a portion of the Notes shall be in minimum aggregate amounts of $100,000, or multiples thereof.

(b) Provided that the holders of the Senior Secured Notes have converted all their Senior Secured Notes into shares of Common Stock, the Company may, at its option, require the conversion of all the outstanding Notes (a “Mandatory Conversion”) into shares of fully paid, non-assessable Common Stock. The Company may exercise this option only if for five (5) consecutive trading days, including the last trading day of such period, the Current Market Price (as defined below) of the Common Stock equals or exceeds $1.50 (or its equivalent in NOK), such price to be subject to adjustments in the same manner and for the same events as the Conversion Price in pursuant to Section 11.7(e) and 11.7(f). In order to exercise the Mandatory Conversion, the Company must notify the Purchasers prior to the opening of business on the second trading day after any period in which the last of the conditions in the preceding sentences have been met (a “Mandatory Conversion Notice”). Any Mandatory Conversion Notice shall be automatically deemed a notice for acceleration of the Warrants, which shall automatically become immediately exercisable on receipt of such notice. The notice shall specify the Mandatory Conversion Date and provide the current Conversion Price and Current Market Price of the Common Stock, in each case as of the close of business on the trading day next preceding the date of the notice, and the Mandatory Conversion shall occur at such current Conversion Price set forth in such notice in the manner provided in this Section 11.7. Effective as of the close of business on the Mandatory Conversion Date, the Notes shall be deemed fully paid and shall no longer be deemed to be issued and outstanding, and the Warrants shall be fully exercisable. The Company shall deliver to the Purchasers certificates representing the shares of Common Stock which the Purchasers are entitled to receive as a result of the Mandatory Conversion and shall pay to the Purchasers in cash all interest accrued under the Notes to the Mandatory Conversion Date, as promptly as possible and in any event no later than five (5) Business Days after the Mandatory Conversion Date. The Mandatory Conversion Date will be the second business day after which the Company has issued the notice announcing its intention to exercise its Mandatory Conversion Right. The term “Current Market Price” of the Common Stock for any day means the reported per share closing bid price, regular way, on such day, as reported on the AMEX, or, if the Common Stock is not listed or admitted to trading on the AMEX on such day, on The Oslo Stock Exchange (“OSE”), if the Common Stock is not listed on such securities exchanges, or the Nasdaq NMS or, if the Common Stock is not quoted or admitted to trading on such quotations system, on the principal quotation system in which the Common Stock may be

listed or admitted to trading or quoted or, if not listed or admitted to trading or quoted on any securities exchange or quotation system, the average of the closing bid and asked prices of the Common Stock in the over-the-counter market on the day in question as reported by the National Quotation Bureau Incorporated, or similar generally accepted reporting service, or, if not so available in such manner, as furnished by any AMEX member firm selected from time to time by the Board of Directors of the Company for that purpose or, if not so available in such manner, as otherwise determined in good faith by the Board of Directors of the Company, which determination shall be conclusive.

(c) To elect any Optional Conversion, a Purchaser shall provide to the Company written notice of said election. The parties shall thereafter proceed with diligence to close said conversion not more than 30 days following the Company’s receipt of the election notice. The effective date of any conversion shall be the date on which the election notice is delivered to the Company provided that closing occurs not later than 30 days after a Purchaser’s election notice is delivered to the Company. Any Purchaser electing to convert its Notes shall realize all economic and equitable benefits of conversion from and after said effective date. The Company shall pay to the Purchasers in cash all interest accrued under the Notes through the effective date of any Optional Conversion.

(d) Upon the closing of either an Optional or a Mandatory Conversion, the Company shall authorize and issue to the holders of the Notes a certificate representing the applicable number of shares of Common Stock issuable upon such conversions in accordance with this Section 11.7.

(e) So long as any Notes or Warrants are outstanding, in the event the Company issues equity securities after the date of this Agreement (other than pursuant to the granting of stock options pursuant to employee stock option plans approved by the Company’s stockholders; or the exercise or conversion of outstanding warrants, stock options or convertible securities, including without limitation the conversion of the Senior Secured Notes) with a price of less than US$1 per share, as adjusted, such price per share determined net of all discounts, fees, costs and expenses incurred in connection with such issuance, then the Conversion Price in Section 11.7(a)(i) and the exercise price of the Warrants shall be automatically reset to the lowest net effective price per share, without any further action of the Purchasers. Notwithstanding the foregoing, in no event shall the number of shares of Common Stock issuable to the Purchasers pursuant to this Section 11.7(e) cause the Purchasers to own in excess of 19.9% of the outstanding Common Stock of the Company as at the date of this Agreement unless the Company has obtained the prior approval of its stockholders as required by Section 713 of the AMEX Company Guide as in effect from time to time; provided, however, that the Company shall use its commercially reasonable efforts to diligently seek to obtain such approval of its stockholders.

(f) In the event the number of outstanding shares of Common Stock are changed into a different number or class of shares by reason of any stock split, stock dividend, reverse stock split, reclassification, recapitalization, combination, merger, consolidation or any similar transaction, then the Conversion Price in Section 11.7(a)(i) and the exercise price of the Warrants and the number of shares of Common Stock issuable upon conversion of the Notes and exercise of the

Warrants will be appropriately adjusted to reflect any such event, such that the holders will receive upon either an Optional or a Mandatory Conversion the identical number of shares of Common Stock or other consideration or property to be received by the holders of the Common Stock as if the holders had converted their Notes immediately prior to any such event as such amount would then be adjusted by reason of such stock split, stock dividend, reverse stock split, reclassification, recapitalization, combination, merger, consolidation or other similar transaction. No fractional shares of Common Stock shall be issued upon any Optional or Mandatory Conversion or exercise; instead the Conversion Price and the exercise price of the Warrants shall be appropriately adjusted so that holders shall receive the nearest whole number of shares upon any such conversion or exercise.

Section 11.8. Payment of Special Counsel and other Fees. The Company shall pay or cause to be paid within ten Business Days after receipt of an invoice therefor the reasonable fees, charges and disbursements of your special counsel and the fees of other professionals engaged to represent the Purchasers in connection with this Agreement. The Company’s obligation to pay all such fees shall not to exceed in the aggregate US$75,000 for services rendered by all such counsel and other professionals in connection with the transactions contemplated by the Loan Documents or any amendments thereof.

Section 11.9. Issuing the Press Release and Filing a Current Report of Form 8-K The Company shall issue the Press Release and file a Current Report on Form 8-K with the SEC within four (4) Business Days after the Closing announcing the completion of the purchase and sale of the Notes and Warrants, describing their terms and conditions and attaching a copy of the Press Release as an Exhibit.

(b) Upon receipt of the Farmout Notice, the Purchasers or such Affiliate(s) shall have the right exercisable upon written notice to the Company delivered within a period of thirty (30) days after receipt of the Farmout Notice to elect to exercise the First Offer upon and subject to such Proposed Terms. Provided that the Purchasers or such Affiliate(s) have not exercised their right of First Offer pursuant to Section 12.13.1(a) within 30 days of receipt of the Farmout Notice, the Purchasers and all their Affiliates shall be deemed to have waived such right and the Company or CanArgo Group Member shall be entitled to proceed with the proposed Permitted Farmout Arrangement upon and subject to the

Proposed Terms; provided, however, in the event the Company proposes to revise the Proposed Terms to make them more favorable to the participant in the Permitted Farmout Arrangement, then the Company shall first issue a new Farmout Notice to the Purchasers in accordance with the procedures set forth in this Section 12.13.1 and a new thirty (30) day period shall begin to run from receipt of such Notice within which the Purchasers or their designated Affiliate(s) shall have the right to exercise the First Offer on such revised Proposed Terms.

The Referral by the Applicant shall be in writing and shall specify in reasonable detail the Applicant’s position and a copy shall be delivered contemporaneously to the other party to the dispute (the “Respondent”) who shall have a period of thirty (30) days after receipt of the Referral to respond in writing thereto.

12.13.4 The rights of the Purchasers pursuant to this Section 12.13 shall expire with immediate effect on the earliest to occur of (i) the completion of the Tethys Spin Out; (ii) the repayment or conversion of the Senior Secured Notes; and (iii) the repayment or conversion of the Subordinated Notes.

12.13.5 The rights of First Offer of the Purchasers as set forth in this Section 12.13 shall apply only to Permitted Farmout Arrangements entered into primarily for financial reasons, and shall not apply to Permitted Farmout Arrangements entered into primarily for technical reasons such as accessing special technical skills and capabilities of the counterparty (a “Technical Farmout”). This shall not affect the obligations of the Company or CanArgo Group Member to provide the Purchasers with a Farmout Notice pursuant to Section 12.3.1, nor to acquire the written consent of the Purchasers pursuant to Section 12.3.2.

Section 15.3. Replacement of Notes and Warrants. Upon receipt by the Company of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note or Warrant (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and

(a) in the case of loss, theft or destruction, of a bond or other indemnity reasonably satisfactory to it (provided that if the holder of such Note or Warrant is, or is a nominee for, an original Purchaser or another holder of a Note or Warrant with a minimum net worth of at least the greater of (i) with respect to a loss, theft or destruction of a Note, the principal amount of such Note or (ii) US$5,000,000, and the Company receives a certification from any senior financial officer or other individual with the responsibility for the administration of such Person’s investment in the Notes or Warrants to such effect, such Person’s own duly authorized unsecured agreement of indemnity shall be deemed to be satisfactory), or

(b) in the case of mutilation, upon surrender and cancellation thereof, the Company at its own expense shall execute and deliver, in lieu thereof, a new Warrant dated the Closing Date or a new Note, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or

mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon, as the case may be.

SECTION 16. PAYMENTS ON NOTES.

Section 16.1. Place of Payment. Subject to Section 16.2, payments of principal at the applicable Redemption Price, if any, and interest becoming due and payable on the Notes shall be made in New York, New York at the principal office of the holder of such Note in such jurisdiction. The holder of such Note may at any time, by notice to the Company and each other holder of a Note, change the place of payment of the Notes.

Section 16.2. Home Office Payment. So long as you or your nominee shall be the holder of any Note, and notwithstanding anything contained in Section 16.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal at the applicable Redemption Price, if any, and interest by the method and at the address specified for such purpose below your name in Schedule A, or by such other method or at such other address as you shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, you shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 16.1. Prior to any sale or other disposition of any Note held by you or your nominee you will, at your election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 16.2. The Company will afford the benefits of this Section 16.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by you under this Agreement and that has made the same agreement relating to such Note as you have made in Section 15.2 and in this Section 16.2.

Section 16.3. Taxes. So long as the record and beneficial owner of a Note is a Foreign Lender, all payments due in respect of such Note or any of the other Loan Documents shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto levied under the Code, excluding (i) taxes that are imposed on or measured by the income (including, without limitation, any franchise taxes imposed in lieu thereof) of such Foreign Lender and (ii) all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto levied by any federal, state, provincial, municipal, or other national or multinational governmental authority of any foreign jurisdiction applicable to such Foreign Lender (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under any other Loan Document being hereinafter referred to as “Taxes”). If the Company or any Subsidiary Guarantor shall be required by the Code to deduct any Taxes from or in respect of any sum payable under the Notes or under any other Loan Document, the sum payable shall be increased as may be necessary so that after all required deductions (including deductions applicable to additional sums payable under this Section 16.3) the recipient of such payment receives an amount equal to the sum it would have received had no such deductions been made. The Company or Subsidiary Guarantor shall make all such deductions and shall pay the full amount deducted to the United States Treasury Department in accordance with

applicable law. In addition, the Company or any Subsidiary Guarantor, as applicable, shall pay any present or future stamp, documentary, excise, property, intangible, mortgage recording or similar taxes, charges or levies due and payable under applicable law that arise in connection with the original issuance of the Notes or under any other Loan Document or from the execution, delivery or registration of this Agreement, the Notes or the other Loan Documents (hereinafter referred to as “Other Taxes”). The Company and each Subsidiary Guarantor shall indemnify each of the Purchasers for and hold them harmless against the full amount of Taxes and Other Taxes on amounts payable to or for the account of any Purchaser hereunder, or under the Notes or any other Loan Document and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date such Purchaser makes written demand therefor. Any Purchaser who is not a United States person within the meaning of Code § 7701(a)(30) or comparable provision as the same may be in effect from time to time (a “Foreign Lender”) as to which no withholding tax is required to be paid by the Company shall provide the Company at Closing (and thereafter as may be reasonably required by the Company) with an executed and completed Form W-8 (or such other form or statement as may be required pursuant to the Code or applicable Treas. Regs.) and each holder of a Note shall, on written request therefor, execute and deliver all such additional documentation and cooperate with the Company to provide the Company with reasonable assurance that such tax is not required to be withheld from payments made to such holder. Notwithstanding anything in the foregoing to the contrary in the event the record or beneficial ownership of a Note is transferred to a holder who does not qualify as a Foreign Lender, then the Company’s obligations with respect to such transferee under this Section 16.3 shall, effective on the date of assignment, immediately cease and shall be of no further force and effect.

SECTION 17. EXPENSES, ETC.

Section 17.1. Transaction Expenses. Whether or not the transactions contemplated hereby are consummated (unless such transactions fail to close as a result of any discretionary action or inaction by any Purchaser) and subject to the provisions of Section 11.8, the Company will pay all costs and expenses (including reasonable attorneys’ fees of a special counsel and, if reasonably required, local or other counsel) incurred by you in connection with such transactions and in connection with any amendments, waivers or consents under or in respect of any of the Loan Documents and Warrants (whether or not such amendment, waiver or consent becomes effective), including, without limitation: (a) the reasonable costs and expenses incurred in enforcing or defending (or determining whether or how to enforce or defend) any rights under any of the Loan Documents or in responding to any subpoena or other legal process or informal investigative demand issued in connection with any of the Loan Documents, or by reason of being a holder of any Note, and (b) the reasonable costs and expenses, including financial advisors’ fees, incurred in connection with the insolvency or bankruptcy of the Company or any Material Subsidiary or in connection with any work-out or restructuring of the transactions contemplated hereby and by the Notes; provided, however, notwithstanding anything in the foregoing provided to the contrary, the Company shall not be required to pay: (i) the fees, costs and expenses of more than one special counsel, and, if reasonably required, local or other counsel, for all the Purchasers; (ii) any legal or other professional fees, costs and expenses incurred in connection with or attributable to your or any holder’s breach (as determined by a final, binding and non-appealable order of a court of competent jurisdiction) of any provision of the Loan Documents or the Warrants applicable to such Person and (iii) legal or other professional fees, costs and expenses

incurred prior to (assuming consummation of the transactions contemplated hereby) and in connection with the Loan Documents and any amendments thereof, which exceed $75,000 in the aggregate. The Company will pay, and will save you and each other holder harmless from, all claims in respect of any fees, costs or expenses, if any, of brokers and finders (other than those retained by you or such holder).

Section 17.2. Survival. The obligations of the Company under this Section 17 will survive the execution and delivery or transfer of any Note, the enforcement, amendment or waiver of any provision of this Agreement, any Subsidiary Guaranties or the Notes or the Warrants, and the termination of this Agreement; provided, however, the obligations of the Company under this Section 17 shall expire on the later to occur of either (i) the payment in full of all the Obligations of the Company under the Loan Documents or the Warrants or (ii) the expiration of any applicable statutes of limitations.


SECTION 18.		SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

All representations and warranties contained in the Loan Documents shall survive the execution and delivery of the Loan Documents and the Notes and Warrants, the purchase or transfer by you of any Note or Warrant or portion thereof or interest therein and any partial payment on any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of you or any other holder of a Note and shall expire and be of no further force and effect when all principal, interest and other amounts payable on the Notes shall have been indefeasibly paid in full in accordance with the provisions thereof. The Loan Documents and Warrants embody the entire agreement and understanding between you and the Company and supersede all prior agreements and understandings relating to the subject matter hereof.


SECTION 19.		AMENDMENT AND WAIVER.

Section 19.1. Requirements. This Agreement, the Subsidiary Guaranties and the Notes may be amended, and the observance of any term hereof or of the Subsidiary Guaranties or of the Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of any of the provisions of Section 1, 2, 3, 4, 5, 6, 7 or 23 hereof, or any defined term (as it is used therein), will be effective as to you unless consented to by you in writing, and (b) no such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Section 14 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest on, the Notes, (ii) change the percentage of the principal amount of the Notes the holders of which are required to consent to any such amendment or waiver, or (iii) amend any of Sections 10, 11.7, 13(a), 13(b), 14, 19 or 22. The Warrants may be amended, and the observance of any term thereof may be waived (either retroactively or prospectively) as provided in the Warrants.

Section 19.2. Solicitation of Holders of Notes.

(a) Solicitation. The Company will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with sufficient information,

sufficiently far in advance of the date a decision is required (but in no event less than five (5) Business Days), to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Notes. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 19 to each holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes.

(b) Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security, to any holder of Notes as consideration for or as an inducement to the entering into by any holder of Notes or any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted, on the same terms, ratably to each holder of Notes then outstanding even if such holder did not consent to such waiver or amendment.

(c) Manner of Solicitation. Any such solicitation may be made and written consents received by the Company in accordance with the provisions of Section 20.

Section 19.3. Binding Effect, etc. Any amendment or waiver consented to as provided in this Section 19 applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Note or any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any holder of such Note. As used herein, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented.

Section 19.4. Notes Held by Company, etc. Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement, the Subsidiary Guaranties or the Notes, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding.


SECTION 20.		NOTICES.

All notices and communications provided for hereunder shall be in writing and sent

(a) by telefacsimile if the sender on the same day sends a confirming copy of such notice by a recognized overnight delivery service (charges prepaid), or

(b) by registered or certified mail with return receipt requested (postage prepaid), or

(i) if to you or your nominee, to you or it at the address specified for such communications in Schedule A, or at such other address as you or it shall have specified to the Company in writing,

(ii) if to any other holder of any Note or Warrant, to such holder at such address as such other holder shall have specified to the Company in writing in accordance with the provisions of this Section 20, or

(iii) if to the Company, to the Company at its address set forth at the beginning hereof to the attention of Chief Executive Officer, or at such other address as the Company shall have specified to the holder of each Note in writing.

Notices under this Section 20 will be deemed given only when actually received.


SECTION 21.		REPRODUCTION OF DOCUMENTS.

This Agreement and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by you at the Closing (except the Notes themselves), and (c) subject to the provisions of Section 22, financial statements, certificates and other information previously or hereafter furnished to you, may be reproduced by you by any photographic, photostatic, microfilm, microcard, miniature photographic or other similar process and you may destroy any original document so reproduced. The Company agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by you in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 21 shall not prohibit the Company or any other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.


SECTION 22.		CONFIDENTIAL INFORMATION.

For the purposes of this Section 22, “Confidential Information” means information delivered to you or any holder by or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to the Loan Documents and Warrants that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by you or such holder as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to you or such holder prior to the time of such disclosure through no act or omission by you or any Person authorized to act on your behalf in breach of any duty of confidentiality, (b) subsequently becomes publicly

known through no act or omission by you or any Person acting on your behalf, (c) otherwise becomes known to you other than through disclosure by the Company or any Subsidiary from any Person who has not breached any duty of confidentiality owed to the Company or any Subsidiary, (d) constitutes financial statements delivered to you under Section 9.1 that are otherwise publicly available or (e) concerns or relates to the U.S. federal income tax treatment or U.S. federal income tax structure of the transactions contemplated hereby (and you may disclose to any and all persons, without limitation of any kind, any such information with respect to such U.S. federal income tax treatment and U.S. federal income tax structure). You will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by you in good faith to protect confidential information of third parties delivered to you and you may only use the Confidential Information in connection with the transactions contemplated by the Loan Documents, including, without limitation, the administration, preservation, or enforcement of your rights relating to your investment represented by your Notes, provided that you may deliver or disclose Confidential Information to (i) your directors, officers, employees, agents, attorneys and Affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by your Notes) who are subject to a duty of confidentiality or otherwise agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 22, (ii) your financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 22, (iii) any other holder of any Note who agrees to hold confidential the Confidential Information substantially in accordance with the terms of this Section 22, (iv) any Institutional Investor to which you sell or offer to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 22), (v) any Person from which you offer to purchase any security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 22), (vi) any federal or state regulatory authority having jurisdiction over you, (vii) the National Association of Insurance Commissioners or any similar organization, or any nationally recognized rating agency that requires access to information about your investment portfolio, or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to you, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which you are a party or (z) if an Event of Default has occurred and is continuing, to the extent you may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under your Notes and this Agreement; provided, however, prior to disclosing any Confidential Information pursuant to clauses (vi), (vii) or (viii) (other than in connection with clause (z) of clause (viii)) you shall (if reasonably practicable under the circumstances and provided that you are not legally prohibited from doing so) notify the Company of the proposed disclosure and afford it a reasonable opportunity to seek an injunction or other protective order against the public release of all or any portion of such Confidential Information. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 22 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note or Warrant of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 22.


SECTION 23.		SUBSTITUTION OF PURCHASER.

You shall have the right to substitute any one of your Affiliates as the purchaser of the Notes that you have agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both you and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate repeating and reaffirming the accuracy with respect to it of all of the representations set forth in Section 8 with the same effect as of such acquisition as when you initially acquired your Notes. Upon receipt of such notice, wherever the word “you” is used in this Agreement (other than in this Section 23), such word shall be deemed to refer to such Affiliate in lieu of you. In the event that such Affiliate is so substituted as a purchaser hereunder and such Affiliate thereafter transfers to you all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, wherever the word “you” is used in this Agreement (other than in this Section 23), such word shall no longer be deemed to refer to such Affiliate, but shall refer to you, and you shall have all the rights of an original holder of the Notes and Warrants under this Agreement. Any substitute, by its acceptance of a Note and Warrant registered in its name (or the name of its nominee), shall be deemed to have agreed to become bound by the provisions of the Loan Documents and Warrants applicable to Purchasers and holders and to have made the representations set forth in Section 8.


SECTION 24.		MISCELLANEOUS.

Section 24.1. Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not.

Section 24.2. Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding, any payment of principal at the applicable Redemption Price, if any, or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day.

Section 24.3. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

Section 24.4. Construction and Interpretation. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. All references to immediately available funds or dollar amounts contained in this Agreement shall mean United States dollars. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. The parties acknowledge and agree that (i)

each party and its counsel have reviewed the terms and provisions of this Agreement and have contributed to its revision, (ii) the normal rule of construction, to the effect that any ambiguities are resolved against the drafting party, shall not be employed in the interpretation of it, and (iii) the terms and provisions of this Agreement shall be constructed fairly as to all parties hereto and not in favor or against any party, regardless of which party was generally responsible for the preparation of this Agreement. The terms “herein”, “hereof” or “hereunder” shall refer to the entire Agreement; all references to Sections shall refer to sections of this Agreement; “including” means “and including without limitation.” Words importing the singular also include the plural and vice versa.

Section 24.5. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

Section 24.6. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New York excluding choice of law principles of the law of such State that would require the application of the laws of a jurisdiction other than such State.

Section 24.7 Submission to Jurisdiction. For the purposes of any action or proceeding involving this Agreement, the Notes, the Warrants or any other agreement or document referred to herein or therein, the Company hereby, and shall cause its Subsidiaries to, expressly submit to the nonexclusive jurisdiction of all federal and state courts sitting in the Borough of Manhattan, City and State of New York and consents that any order, process, notice of motion or other application to or by any of said courts or a judge thereof may be served within or without such court’s jurisdiction by registered mail or by personal service, provided that a reasonable time for appearance is allowed. The Company hereby waives, and shall cause its Subsidiaries to irrevocably waive any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement, the Notes or any other agreement or document referred to herein or therein brought in any federal or state court sitting in the City and State of New York, and hereby further irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

Section 24.8 Appointment of Agent for Service of Process.

(a) The Company hereby irrevocably designates and appoints, and shall cause the other CanArgo Group Members to irrevocably designate and appoint ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇▇ LLP, at its office at ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, N.Y. 10169, Attention: ▇▇▇▇▇ ▇ ▇▇▇▇▇▇▇▇▇▇ Esq., as its and their authorized agent, to accept and acknowledge on its behalf service of any and all legal process which may be served in any suit, action or proceeding referred to in Section 24.7 above in any federal or New York State court sitting in the Borough of Manhattan, New York City. The Company represents and warrants that such agent has agreed to accept such appointment. Said designation and appointment shall not be revocable by the Company or any other CanArgo Group Member until all principal, interest and other amounts payable on the Notes shall have been paid in full in accordance with the provisions thereof. If such agent shall cease to act as agent, the Company shall, and shall cause the other

CanArgo Group Members to, designate irrevocably and appoint without delay another such agent.

(b) The Company hereby consents, and shall cause the other CanArgo Group Members to consent to process being served in any suit, action or proceeding referred to in Section 24.7 in any federal or New York State court sitting in the Borough of Manhattan, New York City by service of process upon its agent appointed as provided in subsection (a) above; provided that, to the extent lawful and possible, notice of said service upon such agent shall be mailed by registered or certified air mail, postage prepaid, return receipt requested, to such Person at its address. The Company hereby irrevocably waives, and shall cause the other CanArgo Group Members to irrevocably waive, to the fullest extent permitted by law, all claim of error by reason of service in such manner and agrees that such service shall be deemed in every respect effective service of process upon such Person in any such suit, action or proceeding and shall, to the fullest extent permitted by law, constitute valid and personal service upon and personal delivery to such Person.

(c) Nothing in this Section 24.8 shall affect the right of the Purchasers to serve process in any other manner permitted by law or limit the right of the Purchasers to bring proceedings against the Company or any Material Subsidiary in the courts of any jurisdiction or jurisdictions.

(d) In the event process is served pursuant to Section 24.8(a), the Purchasers shall endeavor to provide the Company with a copy of such process promptly after delivering service of process in accordance with Section 24.8(a). The Parties agree that any delay or failure to comply with this Section 24.8(d) shall in no way constitute a defense of the Company or any other CanArgo Group Member and the Company covenants not to use any such failure as a defense of any kind.

Section 24.9 Company Indemnification. The Company covenants with the Purchaser and each of its directors, officers, shareholders, employees, successors, assigns and agents, as applicable (each, an “indemnified party”) that it will indemnify and hold harmless such indemnified party against any liability of any kind which may be actually incurred or suffered in connection with the conduct of the CanArgo Member Group’s businesses or use of their property except in circumstances where the liability arises from the act or omission of such indemnified party; provided, however, the Company shall not be liable for any punitive, consequential or special damages or liability incurred by such indemnified party, unless such punitive, consequential or special damages arise in connection with a third party claim against you, in which case, the Company’s indemnity obligation shall not be limited.

If any action is brought against an indemnified party in respect of which indemnity may be sought against the Company pursuant to the foregoing paragraph, such indemnified party shall promptly notify the Company in writing of the institution of such action (but the failure so to notify shall not relieve the Company from any liability it may have other than pursuant to this Section 24.9 unless the Company’s defense of any such action is actually prejudiced) and the Company shall promptly assume the defense of such action including the appointment of counsel and payment of expenses. Such indemnified party shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such indemnified party unless (i) the employment of such counsel shall have been authorized in

writing by the Company, (ii) the Company shall not have promptly employed counsel satisfactory to such indemnified party to have charge of the defense of such action or (iii) such indemnified party shall have reasonably concluded that there may be one or more legal defenses available to it which are different from or additional to those available to the Company and the representation of the indemnified party by counsel chosen by the parties represented by such counsel, in any of which events such fees and expenses shall be borne by the Company and the Company shall have the right to direct such the defense of such action on behalf of the indemnified party. Anything in this paragraph to the contrary notwithstanding, the Company shall not be liable for settlement for any such claim or action effected without its written consent. The Company agrees promptly to notify the holders of the commencement of any litigation or proceedings against the Company or any of its officers or directors in connection with the sale of the Notes or any application.

CERTIFICATE FOR COMMON STOCK
PURCHASE WARRANTS

1. Warrant, This Warrant Certificate certifies that , or registered assigns (the “Registered Holder”), is the registered owner of the above indicated number of Warrants expiring on the Warrant Expiration Date, as defined below. One (1) Warrant entitles the Registered Holder to purchase one (1) share of the common stock, $.10 par value (a “Share”), of CanArgo Energy Corporation, a Delaware corporation (the “Company”), from the Company at a purchase price of One Dollar ($1.00) (the “Exercise Price”) at any time during the Exercise Period, as hereinafter defined, upon surrender of this Warrant Certificate with the exercise form hereon duly completed and executed and accompanied by payment of the Exercise Price at the principal office of the Company.

Upon due presentment for transfer or exchange of this Warrant Certificate at the principal office of the Company, a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued in exchange for this Warrant Certificate, subject to the limitations provided herein, upon payment of any tax or governmental charge imposed in connection with such transfer. Subject to the terms hereof the Company shall deliver Warrant Certificates in required whole number denominations to Registered Holders in connection with any transfer or exchange permitted hereunder.

This Warrant is one of several warrants in substantially identical form issued pursuant to the provisions of in that certain Note and Warrant Purchase Agreement dated June 28, 2006 by and among the Company and the Purchasers party thereto (the “Note Purchase Agreement”), and the holders of the Warrant are subject to and entitled to benefits of the provisions thereof and in the event of any conflict between the terms of this Warrant and the terms of the Note Purchase Agreement, the provisions of the Note Purchase Agreement shall govern. Any capitalized terms not otherwise expressly defined herein shall have the meaning ascribed thereto in the Note Purchase Agreement.

2. Restrictive Legends. Each Warrant Certificate shall bear legends substantially in the form of the legends that appear at the beginning of this Warrant Certificate. Each certificate representing Shares issued upon exercise of a Warrant, unless such Shares are then registered under the Securities Act of 1933, as amended (the “Act”), shall bear a legend in substantially the following form:

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITES ACT OF 1933, AS AMENDED (THE“ACT”) OR REGISTERED OR QUALIFIED UNDER THE SECURITIES LAWS OF ANY OTHER JURISDICTION IN RELIANCE UPON EXEMPTIONS FROM SUCH REGISTRATION AFFORDED UNDER THE ACT AND SUCH APPLICABLE LAWS OF OTHER JURISDICTIONS. THE SHARES REPRESENTED HEREBY MAY NOT BE OFFERED, SOLD, HYPOTHECATED OR OTHERWISE TRANSFERRED UNLESS REGISTERED UNDER THE ACT OR AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER THE ACT IS APPLICABLE (IN WHICH CASE THE ISSUER SHALL HAVE RECEIVED AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE ISSUER TO SUCH EFFECT) AND THE PROVISIONS OF ALL OTHER APPLICABLE SECURITIES LAWS ARE OBSERVED.”

Each such certificate representing Shares may also bear such legend relating to the issuance of such Shares pursuant to any applicable securities laws as counsel for the Company shall reasonably deem appropriate.

3. Exercise. Subject to the terms hereof: the Warrants, evidenced by this Warrant Certificate, may be exercised at the Exercise Price in whole or in part at any time during the period (the “Exercise Period”) commencing on the first Business Day six (6) months after the date of issuance hereof and terminating at the close of business on June 28, 2008 or shall be exercised on such sooner date at the election of the Company (a “Mandatory Exercise”) and upon at least thirty (30) days prior written notice to the Registered Holder (the “Mandatory Exercise Notice”) in the event that: (i) the ▇▇▇▇▇▇ M12 well indicates, by way of an independent engineering report, sustainable production, if developed, in excess of 7,500 barrels of oil per day or (ii) all the warrants originally issued under that certain Note and Warrant Purchase Agreement dated as of March 3, 2006 by and among the Company and the purchasers listed therein are exercised by the holders thereof and the average closing price for the Company’s Common Stock on the American Stock Exchange or, if the Common Stock is not then listed for trading on the American Stock Exchange (“AMEX”) then the Oslo Stock Exchange, is above U.S. $1.25 (or its equivalent in NOK, and in any case adjusted for any stock dividends, stock split, its reverse split, recapitalization or reorganization) for a period of five consecutive trading days (the “Warrant Expiration Date”); except that (a) in the case of a Mandatory Conversion (as defined in the Note Purchase Agreement), any and all outstanding Warrants issued under the Note Purchase Agreement and held by Persistency shall

automatically and simultaneously become immediately exercisable on receipt of the Mandatory Conversion Notice, and (b) in the case of a Mandatory Exercise, any and all outstanding Notes issued under the Note Purchase Agreement and held by Persistency hall automatically and simultaneously become immediately convertible on receipt of the Mandatory Exercise Notice. The Exercise Period may also be extended by the Company’s Board of Directors.

A Warrant shall be deemed to have been exercised in immediately prior to the close of business on the date (the “Exercise Date”) of the surrender to the Company at its principal offices of this Warrant Certificate with the exercise form attached hereto executed by the Registered Holder and accompanied by payment to the Company, in cash or by official bank or certified check, of an amount equal to the aggregate Exercise Price, in lawful money of the United States of America.

The person entitled to receive the Shares issuable upon exercise of a Warrant or Warrants (“Warrant Shares”) shall be treated for all purposes as the holder of such Warrant Shares as of the close of business on the Exercise Date. The Company shall not be obligated to issue any fractional share interests in Warrant Shares issuable or deliverable on the exercise of any Warrant or script or cash with respect thereto, but, if Company elects not to issue a fractional share, the Company will pay a cash adjustment in respect of any fraction of a Warrant Share which would otherwise be issuable in an amount equal to the same fraction of the amount by which the market price of a Share on the date of exercise exceeds the Exercise Price, such market price to be determined in good faith by the Board of Directors of the Company. If more than one Warrant shall be exercised at one time by the same Registered Holder, the number of full Shares which shall be issuable on exercise thereof shall be computed on the basis of the aggregate number of full shares issuable on such exercise.

Promptly, and in any event within ten business days after the Exercise Date, the Company shall cause to be issued and delivered to the person or persons entitled to receive the same, a certificate or certificates for the number of Warrant Shares deliverable on such exercise.

The Company may deem and treat the Registered Holder of the Warrants at any time as the absolute owner thereof for all purposes, and the Company shall not be affected by any notice to the contrary. The Warrants shall not entitle the Registered Holder thereof to any of the rights of shareholders or to any dividend declared on the Shares unless the Registered Holder shall have exercised the Warrants and thereby purchased the Warrant Shares prior to the record date for the determination of holders of Shares entitled to such dividend or other right.

4. Net Issue Conversion. Notwithstanding anything in this Warrant to the contrary, the Registered Holder hereof may, subject to the prior concurrence of the Company, in lieu of exercising this Warrant in the manner provided above in Section 3, elect to convert this Warrant into Warrant Shares equal in number to the value of the exercised Warrants by so indicating on the Form of Election to Purchase attached hereto, in which event the Registered Holder shall receive a number of Warrant Shares equal to following shall occur.

[(X multiplied by (Y minus Z)] divided by Y;

where:

X = Number of Warrants Converted

Y = Fair Market Value of one share of Common Stock

Z = Exercise Price

For purposes of the above, “Fair Market Value” shall equal the closing price for the Company’s Common Stock on the Exercise Date, as reported on the AMEX or, if the Common Stock is not then listed for trading on the AMEX, then the dollar equivalent of such closing price as reported on the Oslo Stock Exchange on the Exercise Date.

5. Reservation of Shares and Payment of Taxes. The Company covenants that it will at all times reserve and have available from its authorized Common Stock such number of shares as shall then be issuable on the exercise of outstanding Warrants. The Company covenants that all Warrant Shares which shall be so issuable shall be duly and validly issued, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issue thereof.

The Registered Holder shall pay all documentary, stamp or similar taxes and other government charges that may be imposed with respect to the issuance, transfer or delivery of any Warrants and Warrant Shares on exercise of the Warrants. In the event the Warrants or Warrant Shares are to be delivered in a name other than the name of the Registered Holder of the Warrant Certificate, no such delivery shall be made unless the person requesting the same has paid the amount of any such taxes or charges incident thereto.

6. Registration of Transfer. The Warrant Certificates may be transferred in whole or in part, provided any such transfer complies with all applicable foreign and United States federal and state securities laws and, if requested by the Company, the Registered Holder delivers to the Company an opinion of counsel to that effect, in form and substance reasonably acceptable to the Company. Warrant Certificates to be transferred shall be surrendered to the Company at its principal office. The Company shall execute, issue and deliver in exchange therefore the Warrant Certificate or Certificates which the Registered Holder making the transfer shall be entitled to receive.

The Company shall keep transfer books at its principal office which shall register Warrant Certificates and the transfer thereof. On due presentment of any Warrant Certificate for registration of transfer at such office, the Company shall execute, issue and deliver to the transferee or transferees a new Warrant Certificate or Certificates representing an equal aggregate number of Warrants. All Warrant Certificates presented for registration of transfer or exercise shall be duly endorsed or be accompanied by a written instrument or instruments of transfer in form and substance satisfactory to the Company. The Company may require payment of a sum sufficient to cover any tax or other government charge that may be imposed in connection therewith.

All Warrant Certificates so surrendered, or surrendered for exercise, or for exchange in case of mutilated Warrant Certificates, shall be promptly canceled by the Company and thereafter retained by the Company until the Warrant Expiration Date. Prior to due presentment for registration of transfer thereof the Company may treat the Registered Holder of any Warrant Certificate as the absolute owner thereof (notwithstanding any notations of ownership or writing thereon made by anyone other than the Company), and the Company shall not be affected by any notice to the contrary.

7. Loss or Mutilation. On receipt by the Company of evidence satisfactory as to the ownership of and the loss, theft, destruction or mutilation of this Warrant Certificate, the Company shall execute and deliver, in lieu thereof a new Warrant Certificate representing an equal aggregate number of Warrants. In the case of loss, theft or destruction of any Warrant Certificate, the individual requesting issuance of a new Warrant Certificate shall be required to indemnify the Company in an amount satisfactory to the Company. In the event a Warrant Certificate is mutilated, such Certificate shall be surrendered and canceled by the Company prior to delivery of a new Warrant Certificate. Applicants for a new Warrant Certificate shall also comply with such other reasonable regulations as the Company may prescribe.

8. Adjustment of Shares. The number and kind of securities issuable upon exercise of a Warrant or to be delivered upon the redemption of Warrants hereunder shall be subject to adjustment from time to time upon the happening of certain events (“Adjustment Event”), as follows:

(a) If the Company shall, at any time prior to the complete exercise of the Warrants evidenced hereby, declare or pay to the holders of its outstanding Shares, a dividend payable in any kind of shares of stock or other securities of the Company, or in property, or otherwise than in cash, the Registered Holder upon thereafter exercising the Warrants evidenced hereby as herein provided shall be entitled to receive for the Exercise Price, in addition to one Warrant Share, such additional share or shares of stock or scrip representing fractions of a share or other securities or property as the Registered Holder would have received in the form of such dividend if he had been the holder of record of such Warrant Share on the record date for the determination of common stockholders entitled to receive such dividend.

(b) If the Company shall, while any Warrants evidenced hereby remain in force, effect a recapitalization of such character that the Shares covered hereby shall be changed into or become exchangeable for a larger or smaller number of shares, then thereafter, the number of Shares which the Registered Holder shall be entitled to purchase hereunder, shall be increased or decreased, as the case may be, in direct proportion to the increase or decrease in the number of Shares of the Company by reason of such recapitalization, and the Exercise Price (per Share) shall in the case of an increase in the number of Shares be proportionately reduced, and in the case of a decrease in the number of shares be proportionately increased.

(c) In case of any reorganization of the Company (or any other corporation the stock or other securities of which are at the time receivable upon exercise of a Warrant) or in case the Company (or any such other corporation) shall merge into or with or consolidate with another corporation or convey all or substantially all of its assets to another corporation or enter into a business combination of any form as a result of which the Shares or other securities receivable upon exercise of a Warrant are converted into other stock or securities of the same or another corporation, then and in each such case, the Registered Holder of a Warrant, upon exercise of the purchase right at any time after the consummation of such reorganization, consolidation, merger, conveyance or combination, shall be entitled to receive, in lieu of the Shares or other securities to which such Registered Holder would have been entitled had he exercised the purchase right immediately prior thereto, such stock and securities which such Registered Holder would have owned immediately after such event with respect to the Shares and other securities for which a Warrant may have been exercised

immediately before such event had the Registered Holder exercised the Warrant immediately prior to such event.

(d) In case the Company shall at any time prior to the exercise of a Warrant evidenced hereby make any distribution of its assets to holders of its Shares by way of a liquidating or partial liquidating dividend or by way of a return of capital, or other than as a dividend payable out of earnings or any surplus legally available for dividends under the laws of the state of its incorporation, then the Registered Holder upon thereafter exercising such Warrant as herein provided after the date of record for the determination of those holders of Shares entitled to such distribution of assets, shall be entitled to receive for the Exercise Price, in addition to a Warrant Share, the amount of such assets (or at the option of the Company, a sum equal to the value thereof at the time of such distribution to holders of Shares as such value is determined by the Board of Directors of the Company in good faith) which would have been payable to the Registered Holder had he been the holder of record of such Warrant Share receivable upon exercise of such Warrant on the record date for the determination of those entitled to such distribution.

The Company shall mail to the holder of this Certificate at least twenty (20) days prior to any Adjustment Event a notice specifying the date on which any such Adjustment Event is to occur together with a description thereof.

In each case of an adjustment in the Shares or other securities receivable upon the exercise of a Warrant, the Company shall promptly notify the Registered Holder of such adjustment. Such notice shall set forth the facts upon which such adjustment is based.

9. Reduction in Exercise Price .

(a) The Company’s Board of Directors may, at its sole discretion, reduce the Exercise Price of the Warrants in effect at any time either for the life of the Warrants or any shorter period of time determined by the Company’s Board of Directors. The Company shall promptly notify the Registered Holders of any such reduction in the Exercise Price.

(b) In the event the Company issues equity securities during the life of the Warrant (other than pursuant to the granting of stock options pursuant to employee stock option plans approved by the Company’s stockholders; or the exercise or conversion of outstanding warrants, stock options or convertible securities, including without limitation the conversion of the Senior Secured Notes due July 25, 2009 or the Senior Subordinated Convertible Guaranteed Notes due September 1, 2009) at a price per share of Common Stock or common stock equivalent less than the Exercise Price then in effect, such price per share determined net of all discounts, fees, costs and expenses incurred in connection with such issuance, then the Exercise Price shall be automatically reset to the lowest net effective price per share, without any further action of the holder of the Warrant. Notwithstanding the foregoing, in no event shall the number of Shares issuable to the holders of the Warrants pursuant to this Section 8 cause the holders of the Warrants collectively to own in excess of 19.9% of the outstanding Common Stock of the Company as at the date of the Note Purchase Agreement unless the Company has obtained the prior approval of its stockholders as required by Section 713 of the AMEX Company Guide as in effect from time to time, provided, however, that the Company shall use commercially reasonable efforts to diligently seek to obtain such approval of its stockholders.

10. Notices. All notices, demands, elections, requests and communications provided for hereunder shall be in writing and sent

(a) by telefacsimile if the sender on the same day sends a confirming copy of such notice by a recognized overnight delivery service (charges prepaid), or

SCHEDULE 7.3
DISCLOSURE MATERIALS

SECTIONS 7.3 AND 7.5

As reported in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and subsequently in the Company’s Quarterly Report on Form 10-Q, as amended, for the fiscal quarter ended March 31, 2006, the Company identified a number of deficiencies that were symptomatic of and contributed to the overall material weakness relating to the financial statement close process identified in the Company’s evaluation of the effectiveness of its internal control over financial reporting as of December 31, 2005. The Company also identified a material weakness relating to sufficient controls being in place to ensure adequate review of the application of generally accepted accounting principles relating to non-routine transactions, estimates and financial statement disclosures. As indicated in the Annual Report on Form 10-K for the fiscal year ended December 31, 2005, the Company intends to remediate such deficiencies and has undertaken a process to remediate them; however, no representation or warranty is being made as to the schedule for completion of such remediation process and, its failure to complete this remediation process may adversely affect its ability to accurately report its financial results in a timely manner.

As a result of recent publications and guidance from the Securities and Exchange Commission (“Commission”) and the Company’s ongoing internal control assessment process for 2005, the Company now believes the identified material weaknesses discussed above mean that its disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) were ineffective as of December 31, 2005 and for the fiscal quarter ended March 31, 2006. Accordingly, it now believes that the material weaknesses discussed above mean that it cannot fully ensure that the information required to be disclosed by it in the reports it files or submits under the Exchange Act with the Commission (1) is recorded, processed, summarized and processed within the time period specified in the Commission’s rules and forms and (2) is accumulated and communicated to the management, including principal executives and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

SECTIONS 7.10 AND 7.15

Under the terms of the service agreement dated January 27, 2005 between Ninotsminda Oil Company Limited (“NOC”) and Saipem S.p.A (“Saipem”), NOC had an obligation to provide irrevocable standby letters of credit to Saipem to guarantee payment by NOC under the agreement. Three standby letters of credit in the aggregate amount of $3,900,000 were issued by HSBC International Limited (“HSBC”) on the basis that they were 100% cash collateralized pursuant to the security interest agreement between the Company and HSBC dated February 2, 2005. One of the letters of credit in the sum of $1,100,000 expired on July 15, 2005. The second letter of credit in the sum of $2,250,000 was to expire on October 30, 2005 and the final letter of credit for $550,000 was to expire on December 30, 2005. The parties agreed to an extension of both letters of credit to June 30, 2006 and August 29, 2006 respectively.

The Senior Secured Notes are secured by a security interest in all the Company’s assets, including its principal Guernsey bank account, as well as senior ranking guarantees from each other CanArgo Group Member and pledges of all of the outstanding capital stock of

Ninotsminda Oil Company Limited (a limited liability company incorporated under the laws of the Republic of Cyprus), CanArgo Limited (a company incorporated under the laws of the Bailiwick of Guernsey) and Tethys Petroleum Investments Limited (a company incorporated under the laws of the Bailiwick of Guernsey).

The Subordinated Notes are guaranteed on a basis subordinated in right of payment to the payment of the Senior Secured Notes and the other “Senior Indebtedness” as defined under the Subordinated Note Purchase Agreement by the Company’s Material Subsidiaries.

SECTION 7.9 — TAXES

The Company was delinquent in filing income tax and information returns required by tax authorities in Canada and the United States during the fiscal years 2002 and 2003. These returns have now been filed and any payments shown to be due thereunder have now been made.

The Company’s two Cypriot Subsidiaries, CanArgo Norio Limited and Ninotsminda Oil Company Limited, are up to date with their tax assessments as estimates have been filed with the Cypriot tax authorities. However, neither company has filed its official tax return pending finalization of each entities audited accounts.

SECTION 7.19 — BASIC DOCUMENTS

CanArgo (Nazvrevi) Limited has previously received confirmation from the relevant licensing authority that its minimum work programme obligations had been met under the Nazvrevi PSC. Nevertheless, it has since been verbally suggested by the Georgian State that there may be a case that CanArgo (Nazvrevi) Limited should be required to drill a well as part of this commitment. Whilst CanArgo (Nazvrevi) Limited would contest this view, a well is planned subject to suitable commercial terms being agreed with respect to the proposed gas offtake agreement.
