                                       16

        terms of the Cukurova Warranties, acknowledges that Alfa is entering
        into this Agreement in reliance on the Cukurova Warranties and may treat
        them as conditions of this Agreement; provided, however, that Cukurova
        Warranties shall not be given in relation to any Excluded Asset. The
        Cukurova Parties shall deliver the Cukurova Disclosure Letter to Alfa
        before 5.30 p.m. on 7 June and if they do so, Alfa shall notify to
        Cukurova in writing within three business days after delivery of the
        Cukurova Disclosure Letter whether the Cukurova Disclosure Letter is in
        a form and substance which is satisfactory to Alfa, acting in its
        absolute discretion. If Alfa notifies Cukurova that the Cukurova
        Disclosure Letter is in a form and substance which is satisfactory to
        Alfa, the Cukurova Warranties will be deemed to have been given at the
        date of this Agreement subject to any matters fairly disclosed in the
        Cukurova Disclosure Letter.
8.2     The Cukurova Warranties shall be deemed repeated immediately before
        Completion with reference to the then existing facts and circumstances,
        subject only to any matter which is fairly disclosed in the Satisfactory
        Cukurova Disclosure Letter (if any). Notwithstanding clause 7.1, no
        right to damages or compensation or right of termination in respect of
        breach of any of the Cukurova Warranties as deemed to have been repeated
        under this clause 8.2 shall arise in consequence of any act or thing
        done or omitted to be done at any time after the date of this Agreement
        as required by this Agreement or at the request of or with the prior
        written approval of Alfa unless such breach occurs as a deliberate act,
        omission or default of either of the Cukurova Parties.
8.3     Each of the Cukurova Warranties is given independently from and shall
        not be limited by reference to any of the others of them or anything
        else contained in this Agreement or any other agreement or document
        referred to herein.
8.4     Save as necessary to give effect to the express terms of this Agreement,
        the Cukurova Parties shall not, and shall procure that the Relevant
        Companies, the Turkcell Group Companies and all other members of
        Cukurova's Group shall not, do, allow or permit before Completion
        anything which is or might cause or constitute or result in a breach of
        any of the Cukurova Warranties as given on the date hereof and/or as
        deemed to be repeated immediately prior to Completion.
8.5     The Cukurova Parties shall forthwith disclose to Alfa in writing any
        matter or thing which may arise or become known to it after the date
        hereof (whether or not prior to Completion) which is or could be a
        breach of or inconsistent with or may render inaccurate or misleading
        any of the Cukurova Warranties as given on the date hereof and/or as
        deemed to be repeated immediately prior to Completion.
                                       17
8.6     In the event of any breach of the Cukurova Warranties or any breach by
        either of the Cukurova Parties of any of its covenants, undertakings or
        obligations under any of the Transaction Documents (and without
        restricting Alfa's rights elsewhere under this Agreement and/or to claim
        damages from either of the Cukurova Parties and on any bases available
        to Alfa in respect of such breach), the Cukurova Parties shall (on a
        joint and several basis) on demand at the sole option of Alfa pay to
        Alfa
        (A)     (i) the Relevant Proportion of the amount by which the value of
                any asset or assets of such Relevant Company or Turkcell Group
                Company is or are less than would have been the case if there
                had been no such breach or (as the case may be) (ii) the
                Relevant Proportion of the amount of any loss and/or liability
                or liabilities of the company in question to the extent that it
                or they would not have existed or would have been less had there
                been no such breach; or
        (B)     either (if Conversion has taken place) the amount by which the
                aggregate value of the Conversion Shares is less or (if
                Conversion has not taken place) the aggregate value of the
                conversion rights of the Convertible Bonds is less than would
                have been the case if there had been no such breach;
        together with an amount equal to any expenses losses or liabilities of
        Alfa and/or such company which it would not have incurred or which would
        not have existed if there had been no such breach; and so that for the
        purposes of the foregoing and in the case only of a breach of paragraphs
        1, 2 or 16 any such loss of Alfa and/or any company shall also include
        the amount of any benefit reasonably expected to be obtained by Alfa or,
        as the case may be, any company which by reason of the breach or the
        matters giving rise to the breach was not or will not be obtained in
        whole or in part.
8.7     The Cukurova Parties hereby irrevocably waive all rights and claims
        which each of them may have against the Company, any Relevant Company or
        any Turkcell Group Company and the officers and employees of the
        Company, any Relevant Company or any Turkcell Group Company in respect
        of any misrepresentation, inaccuracy or omission in or from any
        information or advice given by it or any of its officers or employees to
        the Cukurova Parties (or either of them) to enable it to give any of the
        Cukurova Warranties or to assume any of the obligations assumed or to be
        assumed by it under or pursuant to this Agreement.
8.8     For the purposes of determining the amount payable by the Cukurova
        Parties pursuant to clause 8.6 above in relation to a breach of any Tax
        Warranty, no account shall be taken of the availability of any Relief
        except to the extent that such Relief arises as a result of any matter
        in respect of which either of the Cukurova Parties are liable to make a
        payment pursuant to this clause 8 and such payment has been made in
        full. For the purposes of this clause 8 the term liability shall include
        deferred tax liabilities as determined using the generally accepted
        accounting practice relevant to each particular Relevant Company.
8.9     If any deduction or withholding is required from any payment made
        pursuant to clause 8.6 the amount paid shall be increased so that the
        net amount received by the relevant company is equal, after such
        deduction or withholding, to the amount which would have been paid if
        this clause 8.9 were not part of this Agreement. If the receipt of any
        amount payable under clause 8.6 is taxable on the recipient, the amount
        of tax so payable shall be treated as a deduction or withholding for the
        purposes of this clause so that the amount payable is correspondingly
        increased.
                                       18
9.      ALFA WARRANTIES
9.1     Alfa hereby warrants and represents to the Cukurova Parties (for the

        breach of or inconsistent with or may render inaccurate or misleading
        any of the Alfa Warranties as given on exchange hereof and/or
        immediately prior to Completion.

                recoverable;
        (C)     the maximum aggregate liability of the Cukurova Parties under
                the Cukurova Warranties shall not exceed an amount equal to the
                aggregate of (i) in the case of relevant claims in respect of
                paragraph 1, paragraph 2 or paragraph 16 Schedule 3,
                US$3,300,000,000; or in the case of all other relevant claims,

10.2    Subject as provided below, the liability of Alfa under or in respect of
        the Alfa Warranties shall be limited as follows:
        (A)     no claim under the Alfa Warranties ("a relevant claim") may be

                of the claim concerned has been given to Alfa before the third
                anniversary of Completion; and
        (B)     no relevant claim may be made unless and until the aggregate
                amount of all relevant claims exceeds US$3,000,000 although once

                any other claims shall be recoverable;
        (C)     no relevant claim may be made in respect of loss of opportunity.
10.3    The maximum aggregate liability of Alfa under the Alfa Warranties shall
        not exceed an amount equal to the aggregate of (i) US$25,000,000 and
        (ii) the total amount of any costs charges and expenses incurred by the
        claimants in investigating bringing and/or enforcing any claim(s) or
        rights in respect thereof.
10.4    Any party ("the Claiming Party") entitled to bring a claim ("the
        Principal Claim") under this Agreement in connection with any third
        party claim, action or Proceeding ("a Third Party Claim") shall give the
        party against whom the Principal Claim is being or is to be made (the
        "Defending Party") prompt written notice of such Third Party Claim.
10.5    If the Defending Party so elects, the Defending Party will assume the
        defence of such Third Party Claim, including the employing of counsel
        reasonably satisfactory to the Claiming Party. If the Defending Party
        shall so assume the defence of the Third Party Claim, the Defending
        Party shall consult fully with the Claiming Party before taking (or
        authorising its advisers or agents to take) any material action in
        connection with the defence thereof.
10.6    (A)     Neither the Claiming Party nor the Defending Party will
                (together in this clause 10 "the Parties", each a "Party") and
                the Parties shall (i) procure that neither the Company nor any
                Relevant Company will, and (ii) use their respective best
                endeavours to ensure that no Turkcell Group Company will,
                settle, compromise or consent to any entry of any judgement in
                an ongoing or threatened Third Party Claim, without the prior
                written consent of the Defending Party or the Claiming Party as
                the case may be or, in the case of a Third Party Claim against
                the Company or any of its subsidiaries, the prior written
                consent of the Company, such consent no to be unreasonably
                withheld, and for the purposes of this clause 10.6(A) the
                Claiming Party or the Defending Party or the Company, as the
                case may be, shall be deemed not to be withholding its consent
                unreasonably if it believes, acting reasonably, that the
                settlement or compromise of or the entry of judgement in
                relation to the Third Party Claim would have a material adverse
                effect on its reputation.
        (B)     If the Third Party Claim is being made against the Company or
                any of its Affiliates or if any Party has any claim against any
                other party under this Agreement as a result of any liability
                owed by the Company or any of its Affiliates to a third party,
                then each Party shall procure that no admission of liability
                shall be made on behalf of the Company or of such Affiliate
                without the consent of the Company, such consent not to be
                unreasonably withheld or delayed.
                                       20
10.7    The Claiming Party shall co-operate with the Defending Party and its
        employees and professional advisers in investigating the circumstances
        alleged to give rise to such Third Party Claim and whether and to what
        extent any amount is payable in respect of such claim and for such
        purpose the Claiming Party shall procure that any relevant Affiliate of
        the Claiming Party, including, for the avoidance of doubt, the Company,
        shall give, subject to their being paid all reasonable costs and
        expenses, all such assistance and information as is reasonable.
10.8    Except in the case of a fraudulent misrepresentation, no party shall in
        relation to this Agreement be liable in respect of any representations
        or warranties or similar assurances which are not contained and
        expressly given or assumed by them in this Agreement or any agreement or
        document entered into pursuant hereto or referred to herein.
10.9    Nothing in this Agreement or otherwise shall limit the liability of Alfa
        hereunder where Alfa has been fraudulent or wilfully deceptive.
10.10   Nothing in this Agreement or otherwise shall limit the liability of
        either of the Cukurova Parties hereunder where either of them has been
        fraudulent or wilfully deceptive.
11.     EXCLUDED ASSETS
11.1    The Cukurova Parties shall on or before Completion (or as soon as
        reasonably practicable after Completion) procure the sale of any
        Excluded Assets in accordance with all Legal Requirements.
11.2    Notwithstanding anything to the contrary, the Cukurova Parties agree and
        shall procure that the sale of the Excluded Assets is only effected on
        the basis that any purchaser or transferee thereof shall accept such
        right title and interest as the Company or any of its Affiliates may
        have to the Excluded Assets and subject to such encumbrances and other
        third party rights as may attach to them on completion of the purchase,
        and that no contrary warranties representations or similar assurances
        are made by or on behalf of the Company or any of its Affiliates in that
        regard.
11.3    The Cukurova Parties hereby jointly and severally undertake to Alfa (for
        itself and separately as trustee for the Company and each Relevant
        Company) fully to indemnify and hold harmless and keep indemnified and
        hold harmless Alfa and the Company each Relevant Company and each of
        them against any and all losses costs claims expenses proceedings and
        other liability they or any of them may incur or hereafter incur by
        reason of the existence of, or the sale and purchase or transfer of, all
        or any of the Excluded Assets hereby contemplated and/or in relation to
        or otherwise in respect of the Excluded Assets or any of them and/or any
        obligations and liabilities referable thereto.
12.     POST-COMPLETION OBLIGATIONS
        The Cukurova Parties hereby agree, undertake, and covenant to Alfa and
        to the Company to take, as soon as reasonably practicable following
        Completion (and in any event in sufficient time so as to ensure that the
        following matters are implemented within 14 days after Completion), all
        necessary steps (including without limitation convening board meetings
        and shareholders' meetings) to:
        (A)     appoint (i) to the board of directors of Turkcell Holding and to
                the board of Turkcell, two persons nominated by Alfa (who may,
                at Alfa's sole discretion, be the same or different persons as
                between Turkcell Holding and Turkcell) and (ii) to the board of
                directors of Turkcell, a further director agreed by the parties;
                and
                                       21
        (B)     to secure the resignation from the board of Turkcell Holding of
                two directors previously appointed by Cukurova and the
                resignation from the board of Turkcell of three directors
                previously appointed by ▇▇▇▇▇▇▇▇.
▇▇.     MINORITY INTERESTS AND DEBTS
13.1    Alfa (on the one hand) and the Cukurova Parties (on the other) will
        procure (save as contemplated by this Agreement) as a continuing
        obligation both before and after Completion and for the duration that
        they shall remain holders of Convertible Bonds and/or, as the case may
        be, any shares in the capital of the Company, that:
        (A)     respectively, no member the Alfa Group and no member of the
                Cukurova Group will (directly or indirectly) acquire or hold
                (other than as set out in Schedule 6) any interest (minority or
                otherwise) in any Relevant Company or Turkcell Group Company;
                provided that this clause shall not prohibit any member of the
                Alfa Group or any member of the Cukurova Group from acquiring up
                to fifteen per cent. of the issued and outstanding equity
                securities of Turkcell (but not, for the avoidance, of any other
                Relevant Company or Turkcell Group Company), provided that
                Turkcell remains listed on an internationally recognised stock
                exchange and provided further that such acquisition is made
                through an internationally recognised stock exchange;
        (B)     subject to the prior agreement of the Board, if the opportunity
                arises to acquire any interests in any Relevant Company or
                Turkcell Group Company, the parties shall procure that such
                acquisition is only carried out through the Company.
13.2    Alfa (on the one hand) and the Cukurova Parties (on the other) will
        respectively procure that no member of the Alfa Group and no member of
        the Cukurova Group will (directly or indirectly) acquire or hold any
        debt of any Relevant Company or Turkcell Group Company unless otherwise
        approved in writing by Cukurova, in the case of debts held by any member
        of the Alfa Group or by Alfa in the case of any debt held by any member
        of the Cukurova Group, or as contemplated by this Agreement.
13.3    To the extent that any Alfa Group or member of the Cukurova Group holds
        directly any shares in Turkcell, Alfa shall procure that such member of
        the Alfa Group, and Cukurova shall procure that such member of the
        Cukurova Group, shall vote, and take all other actions in respect of,
        such shares as agreed between Alfa and Cukurova and documented in duly
        adopted resolutions of the board of Directors of the Company.
14.     CONFIDENTIALITY
14.1    The Cukurova parties (on the one hand) and Alfa (on the other) shall
        respectively use (and shall ensure that each member of their/its Group
        shall use) reasonable endeavours to keep confidential (and to ensure
        that its officers, employees, agents and professional and other advisers
        keep confidential) any information:
        (A)     which it may have, or acquire, before or after the date of this
                Agreement in relation to any parties customers, business, assets
                or affairs resulting from:
                (1)     negotiating this Agreement;
                (2)     being a shareholder or bondholder in the Company;
                (3)     having appointees on the board of any Relevant Company;
                        or
                (4)     exercising its rights or performing its obligations
                        under this Agreement; or
                                       22
        (B)     which relates to the contents of this Agreement (or any
                agreement or arrangement entered into pursuant to this
                Agreement),
        and no party shall use for its own business purposes or disclose to any
        third party any such information (collectively, the "Confidential
        Information") without the prior written consent of the other parties. In
        performing its obligations under this clause 1.1(B), each party shall
        apply the confidentiality standards and procedures it applies generally
        in relation to its own confidential information.
14.2    The obligation of confidentiality under clause 14.1 does not apply to:
        (A)     the disclosure (subject to clause 14.3) on a "need to know"
                basis by Alfa to a company which is another member of the Alfa
                Group or Affiliate of Alfa or by either Cukurova Party to a
                company which is another member of the Cukurova Group or an
                Affiliate either of the Cukurova Parties (as the case may be)
                where the disclosure is for a purpose reasonably incidental to
                this Agreement;
        (B)     information which is independently developed by the relevant
                party or acquired from a third party to the extent that it is
                acquired with the right to disclose the same;
        (C)     the disclosure of information to the extent required to be
                disclosed by law, any stock exchange regulation or any binding
                judgement, order or requirement of any court, regulatory body or
                other competent authority;
        (D)     the disclosure of information to any tax authority to the extent
                required for the purposes of the tax affairs of the party
                concerned or any member of its Group;
        (E)     the disclosure (subject to clause 14.3) in confidence to a
                party's professional advisers of information reasonably required
                to be disclosed for a purpose reasonably incidental to this
                Agreement;
        (F)     the disclosure (subject to clause 14.3) by either of Alfa or the
                Cukurova Parties to their respective institutional financiers
                and bankers and the professional advisers to such institutional
                financiers and bankers for a purpose reasonably incidental to
                and to the extent reasonably required by such institutional
                financiers and bankers for the purposes of them considering
                extending financing to the party in question;
        (G)     information which becomes within the public domain (otherwise
                than as a result of a breach of this clause 1.1(B)); or
        (H)     any announcement made in accordance with the terms of clause 19
                (Announcements).
14.3    Each party shall inform (and shall ensure that each member of its Group
        shall inform) any officer, employee, agent or professional or other
        adviser advising it in relation to the matters referred to in this
        Agreement, or to whom it provides Confidential Information, that such
        information is confidential and shall instruct them:
        (A)     to keep it confidential; and
        (B)     not to disclose it to any third party (other than those Persons
                to whom it has already been disclosed in accordance with the
                terms of this Agreement),
        and the disclosing party is responsible for any breach of this clause

        their respective Affiliates (other than a Relevant Company or Turkcell
        Group Company) and which has fallen to be paid by a Relevant Company or
        Turkcell Group Company due to the failure of either of the Cukurova
        Parties or their respective Affiliates aforesaid to pay that Tax when
        due and no such liability to Tax on the part of Alfa, the Company, a
        Relevant Company or Turkcell Group Company will arise if either of the

        disclosed in the Accounts of the relevant company and is fully funded
        and no promise or undertaking (whether legally binding or not) has been
