SECTION 5.     CONDITIONS TO CLOSING.

      Your obligation to purchase and pay for the Notes to be sold to you at the

waived in accordance with the provisions of Section 18:

      Section 5.1.1. Representations and Warranties. Each of the representations
and warranties contained in Section 6 of this Agreement that are not qualified
by materiality shall be true and correct in all Material respects as of the
Closing Date and each of the representations and warranties contained in Section
6 of this Agreement that are qualified by materiality shall be true and correct
as of the Closing Date, with the same force and effect as if made as of the
Closing Date (other than such representations and warranties as are made as of
another date, which shall have been true and correct as of such other date and
such representations and warranties not qualified by materiality shall be true
and correct in all Material respects as of such other date and except as
permitted by this Agreement to change between the date of this Agreement and the
Closing Date).

      Section 5.1.2. Performance; No Default. The Company shall have performed
and complied in all Material respects with all agreements and conditions

or 11.9 (except with respect to transactions disclosed in Schedule 6.15) hereof
had such Sections applied since such date. Without limiting your rights with
respect to a breach of any representations, warranties or covenants herein, your
purchase of the Notes shall be deemed to constitute conclusive evidence of your

required to be performed or complied with by the Company prior to or at the
Closing have been performed or waived to your satisfaction.

      Section 5.1.3. Compliance Certificates.

               (b) Secretary's Certificate. The Company shall have delivered to
         you a certificate certifying as to the resolutions attached thereto and

      Section 6.1. Organization; Power and Authority. Each CanArgo Group Member
is a corporation (or other legal entity) validly existing and in good standing
under the laws of its jurisdiction of 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

Material Adverse Effect. Each 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 to which it is a party and to perform the provisions hereof and
thereof.

      Section 6.2. Authorization, etc. Each of the Loan Documents have been duly
authorized by all necessary corporate action on the part of each CanArgo Group
Member party thereto, and each such Loan Document constitutes, and upon
execution and delivery thereof each such Loan Document 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

or on behalf of the CanArgo Group Members in connection with the transactions
contemplated hereby and the financial statements listed in Schedule 6.5, taken

31, 2004, there has been no change in the financial condition, operations,
business or properties of the CanArgo Group Members taken as a whole except
changes that are reflected in the Company's Quarterly Report on Form 10-Q for
the fiscal quarter ended March 31, 2005, or that individually or in the
aggregate could not reasonably be expected to have a Material Adverse Effect.

      Section 6.4. Organization and Ownership of Shares of Subsidiaries;

         class of its capital stock or similar equity interests outstanding
         owned by any CanArgo Group Member, (ii) of the Company's Affiliates,
         other than the direct and indirect Subsidiaries, (iii) of the Company's

         Lien (except as otherwise disclosed in Schedule 6.4).

               (c) No CanArgo Group Member is a party to, or otherwise subject
         to any legal restriction or any agreement (other than the Loan
         Documents to which it is a party, the agreements listed on Schedule 6.4
         and customary limitations imposed by corporate or fiscal law statutes)
         restricting the ability of such CanArgo Group Member to pay dividends

periods involved except as set forth in the notes thereto (subject, in the case
of any interim financial statements, to normal year-end adjustments and the
absence of footnotes).

      Section 6.6. Compliance with Laws, Other Instruments, etc. The execution,
delivery and performance by each of the CanArgo Group Members of the Loan
Documents to which they are a party will not (i) contravene, result in any
breach of, or constitute a default under, or result in the creation of any Lien,
except as contemplated in the Loan Documents, in respect of any property of the
Company or any Subsidiary Guarantor under, any indenture, mortgage, deed of
trust, loan, purchase or credit agreement, lease, Charter Document, or any other
agreement or instrument to which the Company or any Subsidiary Guarantor is
bound or by which the Company or any Subsidiary Guarantor or any of their
respective properties may be bound or affected, (ii) conflict with or result in
a breach of any of the terms, conditions or provisions of any order, judgment,
decree, or ruling of any court, arbitrator or Governmental Authority applicable
to the Company or any Subsidiary Guarantor or (iii) violate any provision of any
current statute or other rule or regulation of any Governmental Authority
applicable to the Company or any CanArgo Group Member, in each case the effect
of which could have a Material Adverse Effect.

      Section 6.7. Governmental Authorizations, etc.. No consent, approval or
authorization of, or registration, filing or declaration with, any Governmental

         other CanArgo Group Member, threatened against or affecting the Company
         or any other CanArgo Group Member or any property of the Company or any
         other CanArgo Group Member in any court or before any arbitrator of any
         kind or before or by any Governmental Authority that, individually or
         in the aggregate, could reasonably be expected, if adversely
         determined, to have a Material Adverse Effect.

               (b) Neither the Company nor any other CanArgo Group Member is in
         default under any term of any agreement or instrument to which it is a
         party or by which it is bound, or any order, judgment, decree or ruling
         of any court, arbitrator or Governmental Authority or is in violation
         of any applicable law, ordinance, rule or regulation (including without
         limitation Environmental Laws) of any Governmental Authority, which

income or franchises, or otherwise payable by them, to the extent such taxes and
assessments have become due and payable and before they have become delinquent,
except for any taxes and assessments (i) the amount of which is not individually
or in 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

liabilities of the Company and each other CanArgo Group Member have been paid
for the seven prior fiscal years (including the current fiscal period) up to and
including the fiscal year ended December 31, 2004. No CanArgo Group Member has

         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,

                                      -8-
<PAGE>
               (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 occurred with respect to any "pension plan"
         (as defined in ERISA) for which the Company would have any liability;
         the Company has not incurred and does not expect to incur 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 6.13. 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 any similar securities for sale to, or solicited any offer to buy
any of the same from, 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 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 from such Purchaser) set forth
in Section 7 on which the Company will rely.

      Section 6.14. Use of Proceeds; Margin Regulations. The Company will apply
the proceeds of the sale of the Notes as set forth in Schedule 6.14. No part of
the proceeds from the sale of the Notes 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 6.15. Existing Indebtedness; Future Liens.

               (a) Schedule 6.15 sets forth a complete and correct list of all
         outstanding Indebtedness of the Company. Since March 31, 2005, except
         as set forth on Schedule 6.15, 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


                                      -9-
<PAGE>
         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 6.15, 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, whether now owned or hereafter acquired, to be
         subject to a Lien not permitted by Section 11.3.

      Section 6.16. Foreign Assets Control Regulations, etc.. Neither the sale
of the Notes 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 6.17. 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 Public Utility Holding Company Act of 1935, as
amended, the ICC Termination Act of 1995, as amended, or the Federal Power Act,
as amended.

      Section 6.18. Environmental Matters. 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 the Company or any other CanArgo Group Member or any of their
respective real properties now or formerly owned, leased or operated by any of
them or other assets, alleging any damage to the environment or violation of any
applicable Environmental Laws, except, in each case, such as could not
reasonably be expected to result in a Material Adverse Effect. Except as
disclosed in Schedule 6.18:

               (a) neither the Company nor any other CanArgo Group Member has
         been notified of any claim, public or private, regarding a violation of

         formerly owned, leased or operated by any of them or to other assets or
         their use, except, in each case, such as could not reasonably be
         expected to result in a Material Adverse Effect;

               (b) neither the Company nor any other CanArgo Group Member has
         stored any Hazardous Materials, except Hydrocarbons, on real properties
         now or formerly owned, leased or operated by any of them or has
         disposed of any Hazardous Materials in a manner contrary to any
         applicable Environmental Laws in each case in


                                      -10-
<PAGE>
         any manner that could reasonably be expected to result in a Material
         Adverse Effect; and

               (c) all buildings on all real properties now owned, leased or
         operated by the Company or any other CanArgo Group Member are in
         compliance with applicable Environmental Laws, except where failure to
         comply could not reasonably be expected to result in a Material Adverse
         Effect.

      Section 6.19. Basic Documents. Save as disclosed in Schedule 6.19, with
respect to the Basic Agreements:

               (a) no Basic Agreement has been Impaired and is not in full force

         constitutes a valid and binding obligation of each CanArgo Group Member

         Adverse Effect;

               (c) no party to any Basic Agreement has given or to the Knowledge
         of the Company has threatened to give notice of any action to

               (d) the execution and delivery of this Agreement and the
         consummation of the transactions contemplated by this Agreement will
         not result in a breach of, a default under, or other violation of the
         provisions of any Basic Agreement;

               (e) the Basic Documents constitute all Material contracts and
         agreements to which the CanArgo Group Members are a party and the
         Purchasers have received a certified copy of each Basic Agreement to
         which the CanArgo Group Members are a party, in each case as in effect
         on the date of delivery, and each amendment, modification or supplement
         thereto;

         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 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 upon their conversion, the 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 except as
         contemplated by the Registration Rights Agreement, upon their
         conversion, the 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" under Rule 501(a) of the Securities Act.

               (c) You understand that you must bear the economic risk of an
         investment in the Notes and the shares of Common Stock issuable upon
         conversion of the Notes because, among other reasons, the offering and
         sale of Notes and except to the extent contemplated by the Registration
         Rights Agreement, the Common Stock have not been and will not be
         registered under applicable Securities Laws; the Notes and the shares
         of Common Stock issuable upon conversion of the Notes are "restricted
         securities" as defined in Rule 144 promulgated under the Securities Act
         and, therefore, the Notes and such shares cannot be sold unless such
         sales are subsequently


                                      -12-

         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.

               (d) You have sufficient knowledge and experience in financial and
         business matters so as to be capable of evaluating the merits and risks
         of your investment in the Notes and the shares of Common Stock issuable
         upon conversion of the Notes and you are capable of bearing the
         economic risks of such investment, including a complete loss of your
         investment.

      Section 7.2. 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 their
conversion 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.

      Section 7.3. Source of Funds. You represent and warrant to the Company
that at least one of the following statements is an accurate representation as
to each source of funds (a "Source") to be used by you to pay the purchase price
of the Notes to be purchased by you hereunder:

               (a) the Source is an "insurance company general account" within

         reserves and liabilities of such general account (exclusive of separate

               (b) the Source is either (i) an insurance company pooled separate
         account, within the meaning of PTE 90-1 (issued January 29, 1990), or
         (ii) a bank collective investment fund, within the meaning of the PTE
         91-38 (issued July 12, 1991) and, except as you have disclosed to the

         plan or group of plans maintained by the same employer or employee
         organization beneficially owns more than 10% of all assets allocated to
         such pooled separate account or collective investment fund; or

               (c) the Source constitutes assets of 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), no employee benefit plan's assets that are
         included in such investment fund, when combined with the assets of all
         other employee benefit plans established or maintained by the same
         employer or by an affiliate (within the meaning of

         Section V(c)(1) of the QPAM Exemption) of such employer or by the same
         employee organization and managed by such QPAM, exceed 20% of the total
         client assets managed by such QPAM, the conditions of Part I(c) and (g)
         of the QPAM Exemption are satisfied, neither the QPAM nor a person
         controlling or controlled by the QPAM (applying the definition of
         "control" in Section V(e) of the QPAM Exemption) owns a 5% or more
         interest in the Company and (i) the identity of such QPAM and (ii) the
         names of all employee benefit plans whose assets are included in such
         investment fund have been disclosed to the Company in writing pursuant
         to this paragraph (c); or

               (d) the Source is a governmental plan; or

               (e) the Source is one or more employee benefit plans, or a
         separate account or trust fund comprised of one or more employee
         benefit plans, each of which has been identified to the Company in
         writing pursuant to this paragraph (e); or

               (f) the Source does not include assets of any employee benefit
         plan, other than a plan exempt from the coverage of ERISA.

      As used in this Section 7.3, the terms "employee benefit plan",
"governmental plan", "party in interest" and "separate account" shall have the
respective meanings assigned to such terms in Section 3 of ERISA.

Section 9.5. The Company will give each holder of Notes written notice of each
optional prepayment under this Section 9.1 not less than 90 days and not more
than 120 days prior to the date fixed for such prepayment. Each such notice
shall specify such date, the aggregate principal amount of the Notes to be

be prepaid (determined in accordance with Section 9.2), and the interest to be
paid on the prepayment date with respect to such principal amount being prepaid,
at the Redemption Price pursuant to Section 9.5. Each holder of the Notes will
have the option to receive such prepayment in cash pursuant to this Section 9 or

respective unpaid principal amounts thereof not theretofore called for
prepayment.

Notes pursuant to this Section 9, the principal amount of each Note to be
prepaid shall mature and become due and payable on the date fixed for such

date, at the applicable Redemption Price. From and after such date, unless the
Company shall fail to pay such principal amount when so due and payable,
together with the interest, at the applicable Redemption Price, as aforesaid,
interest on such principal amount shall cease to accrue. Any Note paid or
prepaid in full shall be surrendered to the Company and cancelled and shall not

      Section 9.6. Change in Control.

               (a) Notice of Change in Control or Control Event. The Company
         will, within five Business Days after any Responsible Officer has
         actual and not constructive knowledge of the occurrence of any Change
         in Control or Control Event, give written notice of such Change in
         Control or Control Event to each holder of Notes unless notice in
         respect of such Change in Control (or the Change in Control
         contemplated by such Control Event) shall have been given pursuant to
         subparagraph (b) of this Section 9.6. If a Change in Control has
         occurred, such notice shall contain


                                      -19-
<PAGE>
         and constitute an offer to prepay Notes as described in Section 9.6(c)
         and shall be accompanied by the certificate described in Section
         9.6(f).

               (b) Condition to Company Action. The Company will not take any
         action that consummates or finalizes a Change in Control unless (i) at
         least 15 Business Days prior to such action it shall have given to each
         holder of Notes written notice containing and constituting an offer to
         prepay Notes as described in Section 9.6(c), accompanied by the
         certificate described in Section 9.6(f), and (ii) contemporaneously
         with the action taken to consummate or finalize any such Change in
         Control, it prepays all Notes required to be prepaid in accordance with
         this Section 9.6.

               (c) Offer to Prepay Notes. The offer to prepay Notes contemplated
         by subparagraphs (a) and (b) of this Section 9.6 shall be an offer to
         prepay, in accordance with and subject to this Section 9.6, all, but
         not less than all, the Notes held by each holder (in this case only,
         "holder" in respect of any Note registered in the name of a nominee for
         a disclosed beneficial owner shall mean such beneficial owner) on a
         date specified in such offer (the "Proposed Prepayment Date"). If such
         Proposed Prepayment Date is in connection with an offer contemplated by
         subparagraph (a) of this Section 9.6, such date shall be not less than
         30 days and not more than 90 days after the date of such offer (if the
         Proposed Prepayment Date shall not be specified in such offer, the
         Proposed Prepayment Date shall be the 30th day after the date of such
         offer).

               (d) Acceptance. A Purchaser may accept the offer to prepay made
         pursuant to this Section 9.6 by causing notice of such acceptance to be
         delivered to the Company at least 15 days prior to the Proposed Payment
         Date. A failure by a Purchaser to respond to an offer to prepay made
         pursuant to this Section 9.6 shall be deemed to constitute an
         acceptance of such offer by such Purchaser.

               (e) Prepayment. Prepayment of the Notes to be prepaid pursuant to
         this Section 9.6 shall be the Redemption Price of such Notes, together
         with interest on such Notes accrued to the date of prepayment. The
         prepayment shall be made on the Proposed Prepayment Date.

               (f) Officer's Certificate. Each offer to prepay the Notes
         pursuant to this Section 9.6 shall be accompanied by a certificate,
         executed by a Senior Financial Officer of the Company and dated the
         date of such offer, specifying: (i) the Proposed Prepayment Date; (ii)
         that such offer is made pursuant to this Section 9.6; (iii) the
         principal amount of each Note offered to be prepaid; (iv) the interest
         that would be due on each Note offered to be prepaid, accrued to the
         Proposed Prepayment Date; (v) that the conditions of this Section 9.6
         have been fulfilled; and (vi) in reasonable detail, the nature and date
         or proposed date of the Change in Control.

               (g) Effect on Required Payments. The amount of each payment of
         the principal of the Notes made pursuant to this Section 9.6 shall be
         applied against and reduce each of the then remaining principal
         payments due pursuant to Section 9.6 by


                                      -20-
<PAGE>
         a percentage equal to the aggregate principal amount of the Notes so
         paid divided by the aggregate principal amount of the Notes outstanding
         immediately prior to such payment.

               (h) "Change in Control" Defined. "Change in Control" means (a)
         the Company shall at any time cease to be a publicly held company or
         cease to have its capital stock traded on an exchange or (b) a
         transaction or series of related transactions pursuant to which (i) at
         least fifty-one percent (51%) of the outstanding shares of Common Stock
         of the Company or, on a fully diluted basis, shall subsequent to the
         date of this Agreement be owned by any Person (as hereinafter defined)
         which is not related to or Affiliated with the Company, (ii) the
         Company merges into or with, consolidates with or effects any plan of
         share exchange or other combination with any Person which is not

         disposes of all or substantially all of its assets other than in the
         ordinary course of business.

                        (i) the execution by any CanArgo Group Member of any
                  agreement or letter of intent with respect to any proposed
                  transaction or event or series of transactions or events
                  which, individually or in the aggregate, may reasonably be
                  expected to result in a Change in Control, or

                        (ii) the execution of any written agreement which, when
                  fully performed by the parties thereto, would result in a
                  Change in Control.

SECTION 10.    AFFIRMATIVE COVENANTS.

      The Company covenants, on its behalf and on behalf of all the other
CanArgo Group Members, that so long as any of the Notes are outstanding:

      Section 10.1. Compliance with Law. The Company will and will cause each of
the other CanArgo Group Members to comply with all applicable laws, ordinances
or governmental rules or regulations to which each of them is subject,
including, without limitation, applicable Environmental Laws, in all respects,
and will obtain and maintain in effect all licenses, certificates, permits,
franchises and other governmental authorizations necessary to the ownership of
their respective properties or to the conduct of their respective businesses, in
each case except to the extent that non-compliance with such laws, ordinances or
governmental rules or regulations or failures to obtain or maintain in effect
such licenses, certificates, permits, franchises and other governmental
authorizations could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

      Section 10.2. 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


                                      -21-
<PAGE>
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 10.3. 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 10.4. Payment of Taxes and Claims. The Company will and will cause
each of the other CanArgo Group Members to file all tax returns required to be
filed in any jurisdiction and to pay and discharge all taxes shown to be
properly due and payable on such returns and all other taxes, assessments,
governmental charges, or levies imposed on them or any of their properties,
assets, income or franchises, to the extent such taxes and assessments have
become properly due and payable and before they have become delinquent, and all
claims for which sums have become due and payable that have become a Lien on
properties or assets of the Company or any other CanArgo Group Member, provided
that neither the Company nor any other CanArgo Group Member need pay any such
tax or assessment or claims if (i) the amount, applicability or validity thereof
is contested by the Company or such other CanArgo Group Member on a timely basis
in good faith and in appropriate proceedings, and the Company or such other
CanArgo Group Member has established adequate reserves therefor in accordance
with appropriate GAAP on the books of the Company or such other CanArgo Group
Member or (ii) the nonpayment of all such taxes and assessments and claims in
the aggregate could not reasonably be expected to have a Material Adverse
Effect.

      Section 10.5. Corporate Existence, etc. The Company will at all times
preserve and keep in full force and effect its corporate existence. Subject to
Sections 11.2 and 11.8, 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 11.2.

      Section 10.6. Additional Subsidiaries. All Material Subsidiaries of the
Company formed or acquired after the date of the Closing shall execute a
Subsidiary Guaranty substantially


                                      -22-
<PAGE>
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 10.6, 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 $1,250,000
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 10.7. Conversion of Note. Purchasers shall have the right to
convert each of their Notes as follows:

               (a) At any time a Purchaser may convert all or a portion of the
         outstanding principal into shares of Common Stock of the Company at a
         price per share equal to US$0.90 per share, as such price may be
         adjusted pursuant to Section 10.7(d) and 10.7(e) ("Conversion Price").
         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 issuable upon such conversion in
         accordance with this Section 10.7.

               (d) 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 Ozturk Convertible Loan) with a price
         of less than US$0.90 per share, such price per share determined net of
         all fees, costs and expenses incurred in connection with such issuance,
         then the Conversion Price in Section 10.7(a) shall be automatically
         reset to the lowest net effective price per share, without any further
         action of the Purchasers.

               (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 10.7(a)


                                      -23-
<PAGE>
         and the number of shares of 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 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;
         instead the Conversion Price shall be appropriately adjusted so that
         holders shall receive the nearest whole number of shares upon any
         conversion.

      Section 10.8. Additional Security. Upon the reasonable request of the
Required Holders, the Company shall promptly, and shall promptly cause any
Material Subsidiaries requested by such Required Holders to, provide any
additional security as requested by the Required Holders, including, without
limitation, any additional pledges, charges, collateral assignments, security
agreements and/or any other encumbrance or lien in favor of the Purchasers with
respect to the Company or any of its Material Subsidiaries. In addition, upon
the reasonable request of the Required Holders, the Company shall also provide
or cause any Material Subsidiaries to provide any requested legal opinions
relating to such security and certificates of the Company or any of its Material
Subsidiaries certifying true and correct copies of any authorizing resolutions
relating to such security. The Parties acknowledge and agree that it is the
intent of the Parties to cause the Notes to be secured by all Material assets of
the CanArgo Group Members.

      Section 10.9. Payment of Special Counsel and other Fees. After the
Closing, 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 such fees shall not to exceed in the aggregate
US$100,000.00 for services rendered by all such counsel and other professionals
in connection with the transactions contemplated by the Loan Documents.

      Section 10.10. Payment of Placement Fee. Within ten Business Days after
the Closing, the Company shall pay or cause to be paid the placement fee to
Orion Securities in the amount of US$250,000.00.

      Section 10.11. Termination of Cornell Facilities. Within ten Business Days
after the Closing, Company shall deliver to Purchasers (a) reasonably
satisfactory evidence of the payment of all of the Company's obligations under
the Cornell Facility and any other agreements relating to or arising out of the
Cornell Facility by the payment of the Cornell Facility in full and in cash with
the proceeds from the issuance of the Notes and (b) a copy of the notice of
termination delivered under the Cornell Facility.

with any Affiliate (other than the Company or another Material Subsidiary),
except in the ordinary course and pursuant to the reasonable requirements of the
Company's or such CanArgo Group Member's business and upon fair and reasonable
terms no less favorable to the Company or such CanArgo Group Member than would
be obtainable in a comparable arm's-length transaction with a Person not an
Affiliate.

      Section 11.2. Merger, Consolidation, etc. The Company will not, and will
not permit any other CanArgo Group Member to, consolidate with or merge with any
other corporation or convey, transfer or lease substantially all of its assets

Material Subsidiary of the Company may (x) consolidate with or merge with, or
convey, transfer or lease substantially all of its assets in a single
transaction or series of transactions to, another Material Subsidiary or the
Company and (y) convey, transfer or lease all of its assets in compliance with
the provisions of Section 11.8, provided immediately after giving effect to such

CanArgo Group Member to, directly or indirectly create, incur, assume or permit
to exist (upon the happening of a contingency or otherwise) any Lien on or with

         Liens of carriers, operators, vendors, equipment lessors, warehousemen,

         in each case incidental to, and not interfering with, the ordinary
         conduct of the business of the Company or any of its Subsidiaries,
         provided that such Liens do not, in the aggregate, materially detract

         improvement thereon) acquired or constructed by the Company or any
         other CanArgo Group Member after the date of the Closing, provided that

                        (ii) the principal amount of the Indebtedness secured by
                  any such Lien shall at no time exceed an amount equal to 80%
                  (but 100% in the case of property (or improvement thereon) the

      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 13.2. Other Remedies. 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 13.1, 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. Upon an Event of Default, holders will have,
in addition to all of their other rights arising under any of the Loan Documents
or by operation of law or otherwise (which rights shall be cumulative), all of
the rights and remedies of a secured party under the Uniform Commercial Code or
other applicable law of the jurisdiction where any such Collateral is then
located and will have the right to enter upon any premises where the Collateral
is kept and peacefully retake possession in accordance with the provisions of
the Uniform Commercial Code or such other applicable law.

      Section 13.3. Collateral. Holders will have no obligation to preserve
rights to any Collateral against prior parties or to proceed first against any
Collateral or to marshal any Collateral of any kind for the benefit of any other
creditor of Company or any other Person. Company grants to each holder a license
or other right to use, without charge, Company labels, patents, copyrights,
rights of use of any name, trade secrets, trade names, trademarks and
advertising matter, or any property of a similar nature related to the
Collateral and necessary or convenient to enable holder to complete production
of, advertising for sale and selling any Collateral, and Company's rights under
all such licenses and any franchise, sales or distribution agreements will inure
to the holder's benefit in connection therewith. Holder agrees that it shall, in
connection with the foregoing and in the exercise of its rights hereunder comply
with all applicable laws, rules and regulations promulgated by all Governmental
Authorities with jurisdiction.

      Section 13.4. Costs and Expenses. Company shall pay all costs and expenses
of amending, administering, implementing, perfecting, collecting, defending,
declaring and enforcing holder rights, security interests in the Collateral
under this Agreement or any Security Document or other instrument or 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 13.5. Rescission. At any time after any Notes have been declared
due and payable pursuant to clause (b) or (c) of Section 13.1, the Required
Holders, by written notice to the Company, may rescind and annul any such
declaration and its consequences if (a) the


                                      -34-
<PAGE>
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 18, 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 13.5 will extend to or
affect any subsequent Event of Default or Default or impair any right consequent
thereon.

      Section 13.6. 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 16, 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 13, including, without limitation, reasonable attorneys'
fees, expenses and disbursements actually incurred.

SECTION 14.    REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES.

      Section 14.1. Registration of Notes. The Company shall keep at its
principal executive office a register for the registration and registration of
transfers of Notes. The name and address of each holder of one or more Notes,
each transfer thereof and the name and address of each transferee of one or more
Notes shall be registered in such register. Prior to due presentment for
registration of transfer, the Person in whose name any Note 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. The Company shall give to any holder of a Note that is an
Institutional Investor promptly upon request therefor, a complete and correct
copy of the names and addresses of all registered holders of Notes; provided
that such holder in its request agrees that such information is subject to the
confidentiality provisions of Section 21.

      Section 14.2. Transfer and Exchange of Notes. Upon surrender of any Note
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 Note or its attorney duly authorized in writing and
accompanied by the address for notices of each transferee of such Note or part
thereof), the Company shall execute and deliver, at the Company's expense
(except as provided below), one or more new Notes (as requested by the holder
thereof) in exchange therefor, in an aggregate principal amount equal to the
unpaid principal amount of the surrendered Note. 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 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.
The Company


                                      -35-
<PAGE>
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 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 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 7.

      Section 14.3. Replacement of Notes. 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 (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 is, or is a nominee for, an original Purchaser or another
         holder of a Note with a minimum net worth of at least the greater of
         (i) 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 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 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.

SECTION 15.    PAYMENTS ON NOTES.

      Section 15.1. Place of Payment. Subject to Section 15.2, payments of
principal at the applicable Redemption Price, if any, and interest becoming due
and payable on the Notes shall be made in New York, New York at the principal
office of the holder of such Note in such jurisdiction. The holder of such Note
may at any time, by notice to the Company and each other holder of a Note,
change the place of payment of the Notes so long as such place of payment shall
be either the principal office of the holder of such Note in such jurisdiction
or the principal office of a bank or trust company in such jurisdiction.

      Section 15.2. Home Office Payment. So long as you or your nominee shall be
the holder of any Note, and notwithstanding anything contained in Section 15.1
or in such Note to the contrary, the Company will pay all sums becoming due on
such Note for principal at the applicable Redemption Price, if any, and interest
by the method and at the address specified for


                                      -36-
<PAGE>
such purpose below your name in Schedule A, or by such other method or at such
other address as you shall have from time to time specified to the Company in
writing for such purpose, without the presentation or surrender of such Note or
the making of any notation thereon, except that upon written request of the
Company made concurrently with or reasonably promptly after payment or
prepayment in full of any Note, you shall surrender such Note for cancellation,
reasonably promptly after any such request, to the Company at its principal
executive office or at the place of payment most recently designated by the
Company pursuant to Section 15.1. 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 14.2. The Company will afford the benefits
of this Section 15.2 to any Institutional Investor that is the direct or
indirect transferee of any Note purchased by you under this Agreement and that
has made the same agreement relating to such Note as you have made in Section
14.2 and in this Section 15.2.

special counsel, and, if reasonably required, local or other counsel, for all
the Purchasers; (ii) any legal or other professional fees, costs and expenses
incurred in connection with or attributable to your or any holder's breach (as

jurisdiction) of any provision of the Loan Documents applicable to such Person
and (iii) legal or other professional fees, costs and expenses incurred prior to
and in connection with the Loan Documents, which exceed $100,000 in the
aggregate. The Company will pay, and will save you and each other holder

brokers and finders (other than those retained by you or such holder).

      Section 16.2. Survival. The obligations of the Company under this Section
16 will survive the payment or transfer of any Note, the enforcement, amendment
or waiver of any provision of this Agreement, any Security Documents or the
Notes, and the termination of this Agreement.

<PAGE>
SECTION 17.    SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

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

SECTION 18.    AMENDMENT AND WAIVER.

      Section 18.1. Requirements. This Agreement, the Security Documents and the
Notes may be amended, and the observance of any term hereof or of the Security
Documents or of the Notes may be waived (either retroactively or prospectively),
with (and only with) the written consent of the Company and the Required
Holders, except that (a) no amendment or waiver of any of the provisions of
Section 1, 2, 3, 4, 5, 6, or 22 hereof, or any defined term (as it is used
therein), will be effective as to you unless consented to by you in writing, and
(b) no such amendment or waiver may, without the written consent of the holder
of each Note at the time outstanding affected thereby, (i) subject to the
provisions of Section 13 relating to acceleration or rescission, change the
amount or time of any prepayment or payment of principal of, or reduce the rate
or change the time of payment or method of computation of interest on, the
Notes, (ii) change the percentage of the principal amount of the Notes the
holders of which are required to consent to any such amendment or waiver, or
(iii) amend any of Sections 9, 12(a), 12(b), 13, 18 or 21.

      Section 18.2. Solicitation of Holders of Notes.

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

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


                                      -38-
<PAGE>
         each holder of Notes then outstanding even if such holder did not
         consent to such waiver or amendment.

               (c) Manner of Solicitation.  Any such solicitation may be made
         and written consents received by the Company in accordance with the
         provisions of Section 19.

      Section 18.3. Binding Effect, etc. Any amendment or waiver consented to as
provided in this Section 18 applies equally to all holders of Notes and is
binding upon them and upon each future holder of any Note and upon the Company
without regard to whether such Note has been marked to indicate such amendment
or waiver. No such amendment or waiver will extend to or affect any obligation,
covenant, agreement, Default or Event of Default not expressly amended or waived
or impair any right consequent thereon. No course of dealing between the Company
and the holder of any Note or any delay in exercising any rights hereunder or
under any Note shall operate as a waiver of any rights of any holder of such
Note. As used herein, the term "this Agreement" and references thereto shall
mean this Agreement as it may from time to time be amended or supplemented.

      Section 18.4. Notes Held by Company, etc. Solely for the purpose of
determining whether the holders of the requisite percentage of the aggregate
principal amount of Notes then outstanding approved or consented to any
amendment, waiver or consent to be given under this Agreement, the Security
Documents or the Notes, or have directed the taking of any action provided
herein or in the Notes to be taken upon the direction of the holders of a
specified percentage of the aggregate principal amount of Notes then
outstanding, Notes directly or indirectly owned by the Company or any of its
Affiliates shall be deemed not to be outstanding.

SECTION 19.    NOTICES.

      All notices and communications provided for hereunder shall be in writing

                  such other address as you or it shall have specified to the
                  Company in writing,

                        (ii) if to any other holder of any Note, to such holder
                  at such address as such other holder shall have specified to
                  the Company in writing in accordance with the provisions of
                  this Section 19, or


                                      -39-

                  shall have specified to the holder of each Note in writing.

      Notices under this Section 19 will be deemed given only when actually
received.

SECTION 20.    REPRODUCTION OF DOCUMENTS.

      This Agreement and all documents relating thereto, including, without
limitation, (a) consents, waivers and modifications that may hereafter be
executed, (b) documents received by you at the Closing (except the Notes
themselves), and (c) subject to the provisions of Section 21, financial
statements, certificates and other information previously or hereafter furnished
to you, may be reproduced by you by any photographic, photostatic, microfilm,
microcard, miniature photographic or other similar process and you may destroy
any original document so reproduced. The Company agrees and stipulates that, to
the extent permitted by applicable law, any such reproduction shall be
admissible in evidence as the original itself in any judicial or administrative
proceeding (whether or not the original is in existence and whether or not such
reproduction was made by you in the regular course of business) and any
enlargement, facsimile or further reproduction of such reproduction shall
likewise be admissible in evidence. This Section 20 shall not prohibit the
Company or any other holder of Notes from contesting any such reproduction to
the same extent that it could contest the original, or from introducing evidence
to demonstrate the inaccuracy of any such reproduction.

SECTION 21.    CONFIDENTIAL INFORMATION.

      For the purposes of this Section 21, "Confidential Information" means
information delivered to you or any holder by or on behalf of the Company or any
Subsidiary in connection with the transactions contemplated by or otherwise
pursuant to the Loan Documents that is proprietary in nature and that was
clearly marked or labeled or otherwise adequately identified when received by
you or such holder as being confidential information of the Company or such
Subsidiary, provided that such term does not include information that (a) was
publicly known or otherwise known to you or such holder prior to the time of
such disclosure through no act or omission by you or any Person authorized to
act on your behalf in breach of any duty of confidentiality, (b) subsequently
becomes publicly known through no act or omission by you or any Person acting on
your behalf, (c) otherwise becomes known to you other than through disclosure by
the Company or any Subsidiary from any Person who has not breached any duty of
confidentiality owed to the Company or any Subsidiary, (d) constitutes financial
statements delivered to you under Section 8.1 that are otherwise publicly
available or (e) concerns or relates to the U.S. federal income tax treatment or
U.S. federal income tax structure of the transactions contemplated hereby (and
you may disclose to any and all persons, without limitation of any kind, any
such information with respect to such U.S. federal income tax treatment and U.S.
federal income tax structure). You will maintain the confidentiality of such
Confidential Information in accordance with procedures adopted by you in good
faith to protect confidential information of third parties delivered to you and
you may only use the Confidential Information in connection with the
transactions contemplated by the Loan Documents, including, without limitation,
the administration, preservation, or enforcement of your rights relating to your


                                      -40-
<PAGE>
investment represented by your Notes, provided that you may deliver or disclose
Confidential Information to (i) your directors, officers, employees, agents,
attorneys and Affiliates (to the extent such disclosure reasonably relates to
the administration of the investment represented by your Notes) who are subject
to a duty of confidentiality or otherwise agree to hold confidential the
Confidential Information substantially in accordance with the terms of this
Section 21, (ii) your financial advisors and other professional advisors who
agree to hold confidential the Confidential Information substantially in
accordance with the terms of this Section 21, (iii) any other holder of any Note
who agrees to hold confidential the Confidential Information substantially in
accordance with the terms of this Section 21, (iv) any Institutional Investor to
which you sell or offer to sell such Note or any part thereof or any
participation therein (if such Person has agreed in writing prior to its receipt
of such Confidential Information to be bound by the provisions of this Section
21), (v) any Person from which you offer to purchase any security of the Company
(if such Person has agreed in writing prior to its receipt of such Confidential
Information to be bound by the provisions of this Section 21), (vi) any federal
or state regulatory authority having jurisdiction over you, (vii) the National
Association of Insurance Commissioners or any similar organization, or any
nationally recognized rating agency that requires access to information about

disclosure may be necessary or appropriate (w) to effect compliance with any
law, rule, regulation or order applicable to you, (x) in response to any
subpoena or other legal process, (y) in connection with any litigation to which
you are a party or (z) if an Event of Default has occurred and is continuing, to
the extent you may reasonably determine such delivery and disclosure to be
necessary or appropriate in the enforcement or for the protection of the rights
and remedies under your Notes and this Agreement; provided, however, prior to
disclosing any Confidential Information pursuant to clauses (vi), (vii) or
(viii) (other than in connection with clause (z) of clause (viii)) you shall (if
reasonably practicable under the circumstances and provided that you are not
legally prohibited from doing so) notify the Company of the proposed disclosure
and afford it a reasonable opportunity to seek an injunction or other protective
order against the public release of all or any portion of such Confidential
Information. Each holder of a Note, by its acceptance of a Note, will be deemed
to have agreed to be bound by and to be entitled to the benefits of this Section
21 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 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 21.

SECTION 22.    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 7 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 22), such word shall
be deemed to refer to such Affiliate in lieu of you. In the event that such


                                      -41-
<PAGE>
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 22), 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 under this
Agreement. Any substitute, by its acceptance of a Note 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 7.

SECTION 23.    MISCELLANEOUS.

      Section 23.1. 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 23.2. Payments Due on Non-Business Days. Anything in this
Agreement or the Notes to the contrary notwithstanding, any payment of principal
at the applicable Redemption Price, if any, or interest on any Note that is due
on a date other than a Business Day shall be made on the next succeeding
Business Day without including the additional days elapsed in the computation of
the interest payable on such next succeeding Business Day.

      Section 23.3. Severability. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall (to the full extent permitted by law)
not invalidate or render unenforceable such provision in any other jurisdiction.

      Section 23.4. 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 23.5. 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 23.6. 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 23.7 Submission to Jurisdiction. For the purposes of any action or
proceeding involving this Agreement, the Notes or any other agreement or
document referred to herein or therein, the Company hereby, and shall cause its
Subsidiaries to, expressly submit to the nonexclusive jurisdiction of all
federal and state courts sitting in the Borough of Manhattan, City and State of
New York and consents that any order, process, notice of motion or other
application to or by any of said courts or a judge thereof may be served within
or without such court's jurisdiction by registered mail or by personal service,
provided that a reasonable time for appearance is allowed. The Company hereby
waives, and shall cause its Subsidiaries to irrevocably waive any objection that
it may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement, the Notes or any other
agreement or document referred to herein or therein brought in any federal or
state court sitting in the City and State of New York, and hereby further
irrevocably waives any claim that any such suit, action or proceeding brought in
any such court has been brought in an inconvenient forum.

      Section 23.8 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
         23.7 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 23.7 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,


                                      -43-
<PAGE>
         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 23.8 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 23.8(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 23.8(a). The Parties agree that any delay or failure to
         comply with this Section 23.8(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 23.9 Company Indemnification. The Company covenants with each such
holder that it will indemnify and hold harmless such holder against any
liability of any kind which may be actually incurred or suffered in connection
with the conduct of the CanArgo Member Group's businesses or use of their
property except in circumstances where the liability arises from the act or
omission of such holder; provided, however, the Company shall not be liable for
any punitive, consequential or special damages or liability incurred by such
holder, 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 a holder (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 23.9 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


                                      -44-
<PAGE>
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.

      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.
