March 3, 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 you (the
“Purchaser” and together with the other Purchasers listed in the attached Schedule A
collectively referred to herein as the “Purchasers”) as follows:

SECTION 1. AUTHORIZATION OF NOTES AND WARRANTS.

     The Company will authorize the issue and sale of: (i) US$13,000,000 aggregate principal
amount, of its Senior Subordinated Convertible Guaranteed Notes due September 1, 2009 (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 13 million shares at an
exercise price of $1.37 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 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

-2-

 

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

-3-

 

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 the
Senior Secured 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

-4-

 

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

organization, and is duly qualified as a foreign corporation (or other legal entity) and is in good
standing in each jurisdiction in which such qualification is required by law, other than those
jurisdictions as to which the failure to be so qualified or in good standing could not,

CanArgo Group Member has the legal power and authority to own or hold under lease the properties it
purports to own or hold under lease, to transact the business it transacts, to execute and deliver
the Loan Documents and Warrants to which it is a party and to perform the provisions hereof and

Warrant will constitute (assuming due execution and delivery by the Purchasers to the extent
provided for therein), a legal, valid and binding obligation of the CanArgo Group Member a party
thereto enforceable against such Person in accordance with their respective terms, except as such
enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium,
or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general
principles of equity (regardless of whether such enforceability is considered in a proceeding in
equity or at law).

     Section 7.3. Disclosure. Except as disclosed in Schedule 7.3, this Agreement, the
Loan Documents, the Warrants, the certificates or schedules delivered to you by or on behalf of the
CanArgo Group Members in connection with the transactions contemplated hereby and the financial
statements listed in Schedule 7.5, taken as a whole, do not contain any untrue statement of

Member.

     Section 7.5. Financial Statements. The Company has delivered or has provided access to each

     Section 7.6. Compliance with Laws, Other Instruments, etc. The execution, delivery and
performance by each of the CanArgo Group Members of the Loan Documents and Warrants to which they

     Section 7.9. Taxes. Except as disclosed in Schedule 7.3, the Company and each other
CanArgo Group Member have filed all tax returns that are required to have been filed in any
jurisdiction in the seven prior fiscal years (including the current fiscal period), and have paid
all taxes shown to be due and payable on such returns and all other taxes and assessments levied
upon them or their properties, assets, income or franchises, or otherwise payable by them, to the

the aggregate Material or (ii) the amount, applicability or validity of which is currently being
contested in good faith by appropriate proceedings and with respect to which the Company or any
other CanArgo Group Member, as the case may be, has established adequate reserves in accordance
with applicable GAAP. The charges, accruals and reserves on the books of the Company and each
other CanArgo Group Member in respect of federal, provincial, state or other taxes for all fiscal
periods are adequate in all Material respects. The federal income tax liabilities of the Company

     (a) the Company and each other CanArgo Group Member own or possess all licenses,
permits, franchises, authorizations, patents, copyrights, service marks, trademarks and
trade names, or rights thereto, that individually or in the aggregate are Material to
the conduct of their respective businesses as currently being conducted, without, to the
Knowledge of the CanArgo Group Members, conflict with the rights of others;

     (b) to the Knowledge of the CanArgo Group Members, no product of any CanArgo Group
Member infringes in any Material respect any license, permit, franchise, authorization,
patent, copyright, service mark, trademark, trade name or other right owned by any other
Person; and

     (c) to the Knowledge of the CanArgo Group Members, there is no Material violation

Company or any other CanArgo Group Member.

     Section 7.12. Benefit Plan Compliance.

     (a) The Company is in compliance in all Material respects with all presently
applicable provisions of the ERISA; no “reportable event” (as defined in ERISA) has

liability under (i) Title IV of ERISA with respect to termination of, or withdrawal
from, any “pension plan” or (ii) Sections 412 or 4971 of the Code , including the
regulations and published interpretations thereunder; and each “pension plan” for which
the Company would have any liability that is intended to be qualified under Section
401(a) of the Code is so qualified in all Material respects and nothing has occurred,
whether by action or by failure to act, which would cause the loss of such
qualification.

     (b) Neither the Company nor any ERISA Affiliate of the Company maintains any
Foreign Pension Plan.

     Section 7.13. Private Offering by the Company. Neither the Company nor to the Knowledge of
the Company anyone authorized to act on its behalf has offered the Notes or the Warrants or any
similar securities for sale to, or solicited any offer to buy any of the same from,

-11-

 

or otherwise approached or negotiated in respect thereof with, any Person other than you and not more than 35
other Institutional Investors, each of which has been offered the Notes and Warrants at a private
sale for investment and not with a view to the distribution thereof or any interest therein.
Neither the Company nor to the Knowledge of the Company anyone authorized to act on its behalf has
taken, or will take, any action that would subject the issuance or sale of the Notes to the
registration requirements of Section 5 of the Securities Act; provided, however, the availability
of an exemption from the registration requirements of Section 5 is based upon the accuracy and
completeness of the representations and warranties of each Purchaser (and each other Person
acquiring Notes and Warrants from such Purchaser) set forth in Section 8 on which the
Company will rely.

     Section 7.14. Use of Proceeds; Margin Regulations. The Company will apply the proceeds of the
sale of the Notes and Warrants as set forth in Schedule 7.14, except that to the extent
that the Company makes advances to Tethys or any of its subsidiaries after January 19, 2006, the
Company shall be entitled to retain an equal amount (with interest computed from the date of any
such advance at the rate of 10% per annum) for its own purposes from the proceeds of sale of the Notes and
Warrants. No part of the proceeds from the sale of the Notes and Warrants hereunder will be used,
directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning
of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 207), or for the
purpose of buying or carrying or trading in any securities under such circumstances as to involve
the Company in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or
dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute
more than 5% of the value of the Consolidated Assets of the Company and its Subsidiaries and the
Company does not have any present intention that margin stock will constitute more than 5% of the
value of such assets. 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 7.15. Existing Indebtedness; Future Liens.

     (a) Schedule 7.15 sets forth a complete and correct list of all outstanding
Indebtedness of the Company. Since September 30, 2005, except as set forth on
Schedule 7.15, there has been no Material change in the amounts, interest rates,
sinking funds, installment payments or maturities of the Indebtedness of the Company.
Neither the Company nor any other CanArgo Group Member is in default and no waiver of
default is currently in effect, in the payment of any principal or interest on any
Indebtedness of the Company or any other CanArgo Group Member and no event or condition
exists with respect to any Material Indebtedness of the Company or any other CanArgo
Group Member that would permit (or that with notice or the lapse of time, or both, would
permit) one or more Persons to cause such Indebtedness to become due and payable before
its stated maturity or before its regularly scheduled dates of payment.

     (b) Except as disclosed in Schedule 7.15, neither the Company nor any other
CanArgo Group Member has agreed or consented to cause or permit in the future (upon the
happening of a contingency or otherwise) any of its property,

-12-

 

whether now owned or hereafter acquired, to be subject to a Lien not permitted by
Section 12.3.

     Section 7.16. Foreign Assets Control Regulations, etc.. Neither the sale of the Notes and
Warrants by the Company hereunder nor its use of the proceeds thereof will violate the Trading with
the Enemy Act, as amended, or any of the foreign assets control regulations of the United States
Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or
executive order relating thereto.

     Section 7.17. Status under Certain Statutes. Neither the Company nor any other CanArgo Group
Member is subject to regulation under the Investment Company Act of 1940, as amended, the ICC
Termination Act of 1995, as amended, or the Federal Power Act, as amended.

     Section 7.18. Environmental Matters. Except as disclosed in Schedule 7.18, neither
the Company nor any other CanArgo Group Member has received any notice of any claim, and to the
Knowledge of the CanArgo Group Members, no proceeding has been instituted raising any claim against

	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 has 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)

-14-

 

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 or, under certain circumstances, the common stock of Tethys Petroleum
Investments Limited (“Tethys”), nominal value of £0.10 per share (the “Tethys Common
Stock”), 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 and the Tethys Common Stock, have 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. You represent and warrant to the Company that
you are an “accredited investor” as defined under Rule 501(a) of the Securities Act.

     (c) You understand that you must bear the economic risk of an investment in the
Notes, the Warrants and the shares of Common Stock and Tethys Common Stock issuable
upon their respective conversion and exercise because, among other reasons, the offering

Rights Agreement, the Common Stock have not been and will not be registered under
applicable Securities Laws; the Notes and Warrants and the shares of Common Stock and
Tethys Common Stock issuable upon their respective conversion and exercise are
“restricted securities” as defined in Rule 144 promulgated under the Securities Act and,
therefore, the Notes and Warrants and such shares cannot be sold unless such sales are
subsequently registered under applicable Securities Laws or an exemption from such
registration is available. 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 and Tethys 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

-15-

 

investment in the Notes and the shares of Common Stock and Tethys 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. Without affecting your right to rely on the Company’s
representations and warranties set forth herein, you have been given the opportunity to examine all
documents and to ask questions of, and to receive answers from, the Company and its representatives
and to obtain any additional information which the Company possesses or can acquire without
unreasonable effort or expense concerning the Company, its business affairs, financial condition
and terms and conditions of the purchase of Notes and Warrants and their respective conversion and
exercise as you have requested in order to enable you to evaluate the merits and risks of an
investment in the Notes and upon their conversion the Common Stock and, under certain
circumstances, the Tethys Common Stock.

     Section 8.3. Source of Funds. You represent and warrant to the Company that the source of
funds to be used by you to pay the purchase price of the Notes and Warrants to be purchased by you
hereunder is from your own personal assets and is not: an “insurance company general account”
within the meaning of Department of Labor Prohibited Transaction Exemption (“PTE”) 95-60 (issued
July 12, 1995); an employee benefit plan or group of plans maintained by the same employer or
employee organization or a separate account or trust fund comprised of one or more employee benefit
plans; an insurance company pooled separate account, within the meaning of PTE 90-1 (issued January
29, 1990); a bank collective investment fund, within the meaning of the PTE 91-38 (issued July 12,
1991); an “investment fund” (within the meaning of Part V of the QPAM Exemption) managed by a
“qualified professional asset manager” or “QPAM” (within the meaning of Part V of the QPAM
Exemption); or a governmental plan.

benefit plan”, “governmental plan”,

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 this Section shall not 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

-24-

 

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 (i) convert all or, subject to the limitations
hereinafter set forth, a portion of the outstanding principal into shares of Common
Stock of the Company at a price per share equal to US$1.37 per share, as such price may
be adjusted pursuant to Section 11.7(d) and 11.7(e) (“Conversion
Price”); or (ii), until the first anniversary of the Closing Date, as adjusted pursuant
to Section 12.12 (the “Tethys Option Period”), at the option of the Note holders
convert all, or subject to limitations hereinafter set forth, a portion of the
outstanding principal into Tethys Common Stock at the Tethys Conversion Price per share,
as such price may be adjusted pursuant to Section 11.7(f); provided, however, in
the event that holders of the Notes elect to convert their Notes into Tethys Common
Stock, if Note

-25-

 

holders are prevented from exercising their conversion rights hereunder due to the
collateral constraints imposed by the security agreements securing the Company’s Senior
Secured Notes, then such Tethys Option Period shall be extended to a date which is 30
days after Note holders have received notice that such constraints have expired, have
been waived or eliminated or that they are otherwise no longer applicable. The Company
shall promptly notify Note holders of the existence of, and expiration, waiver or
elimination, or inapplicability of any such constraints. Any such conversions of a
portion of the Notes shall be in minimum aggregate amounts of $100,000, or multiples
thereof.

     (b) To elect any 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 notwithstanding that closing may be delayed
beyond 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.

     (c) Upon the closing of a conversion, the Company shall authorize and issue to such
Purchaser a certificate representing the applicable number of shares of Common Stock or
Tethys Common Stock issuable upon such conversion in accordance with this Section
11.7.

     (d) 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$1.37 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(d) 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; provided, however, that the
Company shall use its commercially reasonable efforts to diligently seek to obtain such
approval of its stockholders.

     (e) 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 

-26-

 

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 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 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.

     (f) In the event the number of outstanding shares of Tethys 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 of Tethys, then the Tethys Conversion Price and
the number of shares of Tethys Common Stock issuable upon conversion of the Notes will
be appropriately adjusted to reflect any such event, such that the holders will receive
upon conversion the identical number of shares of Tethys Common Stock or other
consideration or property to be received by the holders of the Tethys 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 Tethys Common Stock shall be issued upon
any conversion; instead the Tethys Conversion Price shall be appropriately adjusted so
that holders shall receive the nearest whole number of shares upon any such conversion.

     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$75,000.00 for services rendered by all such counsel and other
professionals in connection with the transactions contemplated by the Loan Documents or any
amendments thereof.

limitation, any document or instrument in respect of goods or accounts receivable) of the Company

interest in the Norio PSC and Tbilisi PSC (both as defined in Schedule 7.19) to CNL (Jersey); or

     (a) Except as hereinafter specifically provided, so long as any Purchasers hold
shares of the Common Stock issued to them following conversion of the Notes pursuant to

shareholder rights plan adopted by the Company with a view to impairing or impeding any
hostile take-over or other Change of Control transaction which has not been approved by
the Company’s incumbent Board of Directors.

     (b) Notwithstanding the provisions of Section 12.11(a) to the contrary
provided, the Company may enter into or adopt an anti-takeover defense, “poison pill”,
shareholder rights plan or any other device designed to prevent Purchasers or other Note
holders from acquiring such Equity Interests by means of or in connection with the
direct or indirect forbearance, cancellation or exchange of all or any part of the
Indebtedness evidenced by the Notes.

     (c) Notwithstanding the provisions of Section 12.11(a) to the contrary
provided, the Purchasers hereby agree that so long as any Notes are outstanding and no
Event of Default exists and is continuing and until the expiration of the second
anniversary after the indefeasible satisfaction of all Indebtedness under the Notes,
whether by payment, conversion, exchange or otherwise (other than in connection with any
proceeding under the United States Bankruptcy Code), the Purchasers shall not, without
the express written consent or approval of the incumbent Board of Directors of the
Company, solicit or otherwise seek to effect or participate in a Change of Control of
the Company or a change in the composition of the incumbent Board of Directors by means
of the purchase or offer to purchase of any Equity Interests of the Company, the
solicitation of proxies or written consents, or by voting any Equity Interests acquired
by the Purchasers upon the conversion of Notes pursuant to Section 11.7, in
connection with any solicitation of proxies or written consents or at any regular or
special meeting of shareholders or otherwise.

     Section 12.12. Tethys Advances. Schedule 12.12 details advances and equity investments
in Tethys made as of January 19, 2006. All Tethys cash flow will be retained by Tethys during the

and (ii) payments made to the Company to reimburse it for insurance payments and other direct
project related costs incurred and payments made by the Company on behalf of Tethys to further the
oilfield activities of Tethys or any of its Subsidiaries. If the Company shall advance funds to
Tethys to fund Tethys’ growth after January 19, 2006 in addition to the net proceeds of the sale of
the Notes and Warrants advanced to Tethys pursuant to

-33-

 

Section 7.14, then as of the effective date if the Note holders convert their Notes into
Tethys Common Stock, in the Company’s sole and arbitrary discretion, either:

	 	1)	 	The excess advances will be repaid in cash by
Tethys to the Company in full with interest computed from the date of
each such advance at the rate of 10% per annum or,
	 
	 	2)	 	The excess advances will be converted into
equity in Tethys based on a valuation (after conversion in full of the
Notes) of $52 million plus the excess advances in which case either (i)
the Note holders will be allowed to purchase the Relevant Percentage of
the advances at cost from the Company to retain their proportional
interest in Tethys; or (ii) the percentage interest which the Note
holders will receive in Tethys Common Stock upon conversion will be
adjusted downwards on a pro rata basis.

The foregoing will be subject to review at the request of either the Company or the Required
Holders on March 31, 2007 and March 31, 2008. At such review the parties shall use their best and
good faith efforts to agree on any required adjustments to the foregoing in order to reflect
accurately the intent of the foregoing based upon the facts and circumstances in effect as at such
dates.

	SECTION 14.	 	REMEDIES ON DEFAULT, ETC.

     Section 14.1. Acceleration.

     (a) Subject to the provisions of Section 4, if an Event of Default with
respect to the Company or any other CanArgo Group Member described in paragraph (f) or
(g) of Section 13 (other than an Event of Default described in clause (i) of
paragraph (f) or described in clause (vi) of paragraph (f) by virtue of the fact that
such clause encompasses clause (i) of paragraph (f)) has occurred, all the Notes then
outstanding shall automatically become immediately due and payable.

     (b) Subject to the provisions of Section 4, if any other Event of Default
has occurred and is continuing, the Required Holders may at any time at its or their
option, by notice or notices to the Company, declare all the Notes then outstanding to
be immediately due and payable.

     (c) Subject to the provisions of Section 4, if any Event of Default
described in paragraph (a) or (b) of Section 13 has occurred and is continuing,
any holder or holders of Notes at the time outstanding affected by such Event of Default
may at any time, at its or their option, by notice or notices to the Company, declare
all the Notes held by it or them to be immediately due and payable.

Subject to the provisions of Section 4, upon any Notes becoming due and payable
under this Section 14.1, whether automatically or by declaration, such Notes will
forthwith mature and the entire unpaid principal amount of such Notes at the applicable
Redemption Price, if any, plus all accrued and unpaid interest thereon (to the full extent
permitted by applicable law), shall all be immediately due and payable, in each and every
case without presentment, demand, protest or further notice, all of which are hereby waived.
The Company acknowledges, and the parties hereto agree, that each holder of a Note has the
right to maintain its investment in the Notes free from repayment by the Company (except as
herein specifically provided for), and that the provision for payment at the Redemption
Price by the Company in the event that the Notes are prepaid or are accelerated as a result
of an Event of Default, is intended to provide compensation for the deprivation of such
right under such circumstances.

     Section 14.2. Other Remedies. Subject to the provisions of Section 4, if any Default
or Event of Default has occurred and is continuing, and irrespective of whether any Notes have
become or have been declared immediately due and payable under Section 14.1, the holder of
any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an
action at law, suit in equity or other appropriate proceeding, whether for the specific performance
of any agreement contained herein or in any Note, or for an injunction against a violation of any
of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or
by law or otherwise.

     Section 14.3. Costs and Expenses. Company shall pay all costs and expenses of amending,
administering, implementing, collecting, defending, declaring and enforcing holder rights under
this Agreement, the Notes, any Subsidiary Guaranty or other instrument or

-37-

 

agreement delivered in connection with any of the Loan Documents, including searches and
filings at all times, and holder’s reasonable attorneys’ fees (actually incurred, regardless of
whether any litigation is commenced or default is declared and regardless of tribunal or
jurisdiction) .

     Section 14.4. Rescission. At any time after any Notes have been declared due and payable
pursuant to clause (b) or (c) of Section 14.1, the Required Holders, by written notice to
the Company, may rescind and annul any such declaration and its consequences if (a) the Company has
paid all overdue interest on the Notes and all principal at the applicable Redemption Price, if
any, on any Notes that are due and payable and are unpaid other than by reason of such declaration,
and all interest on such overdue principal at the applicable Redemption Price, if any, and (to the
extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default
Rate, (b) all Events of Default and Defaults, other than non-payment of amounts that have become
due solely by reason of such declaration, have been cured or have been waived pursuant to
Section 19, and (c) no judgment or decree has been entered for the payment of any monies
due pursuant hereto or to the Notes. No rescission and annulment under this Section 14.4
will extend to or affect any subsequent Event of Default or Default or impair any right consequent
thereon.

     Section 14.6. No Waivers or Election of Remedies, Expenses, etc. No course of dealing and no
delay on the part of any holder of any Note in exercising any right, power or remedy shall operate
as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right,
power or remedy conferred by this Agreement or by any Note upon any holder thereof shall be
exclusive of any other right, power or remedy referred to herein or therein or now or hereafter
available at law, in equity, by statute or otherwise. Without limiting the obligations of the
Company under Section 17, the Company will pay to the holder of each Note on demand such
further amount as shall be sufficient to cover all costs and expenses of such holder incurred in
any enforcement or collection under this Section 14, including, without limitation,
reasonable attorneys’ fees, expenses and disbursements actually incurred.

			
	SECTION 15.	 	REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES AND WARRANTS.

     Section 15.1. Registration of Notes and Warrants. The Company shall keep at its principal
executive office a register for the registration and registration of transfers of Notes and
Warrants. The name and address of each holder of one or more Notes and Warrants, each transfer
thereof and the name and address of each transferee of one or more Notes and Warrants shall be
registered in such register. Prior to due presentment for registration of transfer, the Person in
whose name any Note or Warrant shall be registered shall be deemed and treated as the owner and
holder thereof for all purposes hereof, and the Company shall not be affected by any notice or
Knowledge to the contrary.

     Section 15.2. Transfer and Exchange of Notes and Warrants. Upon surrender of any Note or
Warrant at the principal executive office of the Company for registration of transfer or exchange
(and in the case of a surrender for registration of transfer, duly endorsed or accompanied by a
written instrument of transfer duly executed by the registered holder of such

-38-

 

Note or Warrant or its attorney duly authorized in writing and accompanied by the address for
notices of each transferee of such Note or Warrant or part thereof), the Company shall execute and
deliver, at the Company’s expense (except as provided below), one or more new Notes or Warrants (as
requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to
the unpaid principal amount of the surrendered Note or the unexercised portion of the Warrant.
Each such new Note shall be payable to such Person as such holder may request and shall be
substantially in the form of Exhibit 1. Each such new Warrant shall be transferred to such
Person as such holder may request and shall be substantially in the form of Exhibit 2.
Each such new Note shall be dated and bear interest from the date to which interest shall have been
paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have
been paid thereon. Each such new Warrant shall be dated the Closing Date. The Company may require
payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any
such transfer of Notes and Warrants and may request that such transferee, at the Company’s
reasonable cost and expense, provide the Company with an opinion of counsel reasonably acceptable
to the Company and in a form and substance reasonably acceptable to the Company and its counsel to
the effect that such transfer is not subject to registration under applicable Securities Laws.
Notes shall not be transferred in denominations of less than US $100,000, provided that if
necessary to enable the registration of transfer by a holder of its entire holding of Notes, one
Note may be in a denomination of less than US $100,000. Any transferee, by its acceptance of a
Note or 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 applicable to Purchasers and holders and to
have made the representations set forth in Section 8.

     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.

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

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

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

obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or

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,

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

-45-

 

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.

-46-

 

     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 Satterlee Stephens
Burke & Burke LLP, at its office at 230 Park Avenue, Suite 1130, New York, N.Y. 10169,
Attention: Peter A Basilevsky 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

-47-

 

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 punitives, 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 Expiration Date, as hereinafter defined. 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 THIRTY SEVEN CENTS ($1.37) (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 that certain Note and Warrant Purchase Agreement dated March 3, 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 next Business Day after the date of issuance
hereof and terminating at the close of business on March 3, 2008 or such sooner date at the
election of the Company and upon at least thirty (30) days prior written notice to the Registered
Holder in the event that the Manavi M12 well indicates, by way of an independent engineering
report, sustainable production, if developed, in excess of 7,500 barrels of oil per day (the
“Expiration Date”). 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. 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.

5. 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 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.

6. 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.

7. 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.

8. 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) at a price 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, provided, however, that the Company shall use commercially reasonable efforts to
diligently seek to obtain such approval of its stockholders.

9. Notices. All notices, demands, elections, or requests (however characterized or
described) required or authorized hereunder shall be deemed given sufficiently if in writing and
sent by the Company, at its principal executive office, and to the Registered Holder, at the
address of such holder as set forth on the books maintained by the Company.

10. General Provisions. This Warrant Certificate shall be construed and enforced in
accordance with, and governed by, the laws of the State of Delaware, where the Company maintains
its registered offices. Except as otherwise expressly stated herein, time is of the essence in
performing hereunder. The headings of this Warrant Certificate are for convenience in reference
only and shall not limit or otherwise affect the meaning hereof.

DISCLOSURE MATERIALS

SECTIONS 7.3 AND 7.5

As reported in the Company’s Annual Report on Form 10-K, as amended, for the fiscal year ended
December 31, 2004 and subsequently in the Company’s Quarterly Reports on Form 10-Q, as amended, for
the fiscal quarters ended March 31, 2005, June 30, 2005 and September 30, 2005, 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,
2004. 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 June 30, 2005 and September 30, 2005 Quarterly Reports, the Company has remediated several
of such deficiencies and has undertaken a process to remediate the remaining deficiencies; however,
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, 2004 and for the fiscal quarters ended March 31, 2005,
June 30, 2005 and September 30, 2005. 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).

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.

UK-Ran are in breach of their obligations under the unanimous shareholder agreement (“USA”)
for UK-Ran which provided that Zhoda would conduct all of its oil and gas activities in the
Republic of the Ukraine through UK-Ran; and (ii) that the plaintiffs are due to be paid
dividends under the Overriding Royalty Agreements between the plaintiffs and UK-Ran.
