TURKCELL ILETISIM HIZMETLERI AS AND ITS SUBSIDIARIES

NOTES TO THE CONSOLIDATED INTERIM FINANCIAL STATEMENTS
As at and for the three months ended 31 March 2006
(Amounts expressed in thousands of US dollars unless otherwise indicated except
share amounts)
--------------------------------------------------------------------------------


1.   Significant accounting policies and operations

     Turkcell Iletisim Hizmetleri Anonim Sirketi (the "Company") was
     incorporated in Turkey on 5 October 1993 and commenced its operations in
     1994. It is engaged in establishing and operating a Global System for
     Mobile Communications ("GSM") network in Turkey and neighboring states.

     In April 1998, the Company signed a license agreement (the "License") with
     the Ministry of Transportation and Communications of Turkey (the "Turkish
     Ministry"), under which it was granted a 25 year GSM license in exchange
     for a license fee of $500,000. The License permits the Company to operate
     as a stand-alone GSM operator and frees it from some of the operating
     constraints in the Revenue Sharing Agreement, which was in effect prior to
     the License. Under the License, the Company collects all of the revenue
     generated from the operations of its GSM network and pays the
     Undersecretariat of Treasury (the "Turkish Treasury") an ongoing license
     fee equal to 15% of its gross revenue from Turkish GSM operations. The
     Company continues to build and operate its GSM network and is authorized
     to, among other things, set its own tariffs within certain limits, charge
     peak and off-peak rates, offer a variety of service and pricing packages,
     issue invoices directly to subscribers, collect payments and deal directly
     with subscribers.

     On 25 June 2005, the Turkish government declared that GSM operators are
     required to pay 10% of their existing monthly ongoing license fee to the
     Ministry of Transportation as a universal service fund contribution in
     accordance with Law No 5369. As a result, starting from 30 June 2005, the
     Company pays the 90% of the ongoing license fee to the Turkish Treasury and
     10% to the Ministry of Transportation as universal service fund.

     In July 2000, the Company completed an initial public offering with the
     listing of its ordinary shares on the Istanbul Stock Exchange and American
     Depositary Shares, or ADSs, on the New York Stock Exchange.

     Two significant founding shareholders, TeliaSonera AB and the Cukurova
     Group own approximately 37.1% and 27.1%, respectively, of the Company's
     share capital, and are ultimate counterparties to a number of transactions
     that are discussed in the related party footnote. On 28 November 2005, upon
     completion of a series of transactions, Alfa Telecom Turkey Limited
     ("Alfa"), an affiliate of Alfa Telecom, one of Russia's leading private
     telecommunications investors, acquired 13.2% indirect ownership in the
     Company.

     The consolidated interim financial statements of the Company as at and for
     the three months ended 31 March 2006 comprise the Company and its sixteen
     subsidiaries (together referred to as the `Group') and the Group's interest
     in one associate. The Company's, subsidiaries' and associate's separate
     interim financial statements are prepared as at and for the three months
     ended 31 March 2006. The Group's interim financial statements were
     authorized for issue by the Board of Directors on 10 May 2006.

(a)  Statement of compliance

     The consolidated interim financial statements have been prepared in
     accordance with International Financial Reporting Standards (IFRSs) and its
     interpretations adopted by the International Accounting Standards Board
     (IASB). These are the Group's first consolidated interim financial
     statements for part of the period covered by the first IFRS annual
     financial statements and International Financial Reporting Standard No. 1
     ("IFRS 1") "First-time Adoption of IFRS" has been applied.

     An explanation of how the transition to IFRSs has affected the reported
     financial position, financial performance and cash flows of the Group is
     provided in Note 29. This Note includes reconciliations of equity and
     income statement for comparative periods reported under USGAAP (previous
     GAAP) to those reported for those periods under IFRSs.

     practice and tax regulations applicable in each subsidiary's respective
     country of residence.

     The accompanying consolidated interim financial statements are based on
     these statutory records, with adjustments and reclassifications for the
     purpose of fair presentation in accordance with IFRS. The consolidated
     interim financial statements are presented in US Dollars, rounded to the
     nearest thousand. They are prepared on the historical cost basis adjusted
     for the effects of inflation during the hyperinflationary period lasted by
     31 December 2005, except that the following assets and liabilities are
     stated at their fair value: derivative financial instruments, financial
     instruments held for trading and financial instruments classified as
     available-for-sale.

     The preparation of interim financial statements in conformity with
     International Accounting Standard No. 34 (IAS 34) "Interim Financial
     Reporting" requires management to make judgments, estimates and assumptions
     that affect the application of policies and reported amounts of assets and
     liabilities, income and expenses. The estimates and associated assumptions
     are based on historical experience and various other factors that are
     believed to be reasonable under the circumstances, the results of which
     form the basis of making the judgments about carrying values of assets and
     liabilities that are not readily apparent from other sources. Actual
     results may differ from these estimates.

     The estimates and underlying assumptions are reviewed on an ongoing basis.
     Revisions to accounting estimates are recognized in the period in which the
     estimate is revised if the revision affects only that period or in the
     period of the revision and future periods if the revision affects both
     current and future periods.

     Judgements made by management in the application of IFRSs that have
     significant effect on the consolidated interim financial statements and
     estimates with a significant risk of material adjustment in the next year
     are discussed in Note 28.

     Financial statements for the year ended 31 December 2005 were restated for
     the changes in the general purchasing power of the functional currency
     based on International Accounting Standard No. 29 ("IAS 29") "Financial
     Reporting in Hyperinflationary Economies". IAS 29 requires that financial
     statements prepared in the currency of a hyperinflationary economy be
     stated in terms of the measuring unit current at the balance sheet date and
     that corresponding figures for previous periods be restated in the same
     terms. One characteristic that necessitates the application of IAS 29 is a
     cumulative three-year inflation rate approaching or exceeding 100%. Three
     years inflation rate in Turkey has been 36% as at 31 December 2005, based
     on the Turkish nation-wide wholesale price indices announced by the State
     Statistics Association ("SSA"). However, IAS 29 does not establish the rate
     of 100% as an absolute rate at which hyperinflation is deemed to arise. It
     is a matter of judgment when restatement of financial statements in
     accordance with IAS 29 becomes necessary. Moreover, hyperinflation is also
     indicated by characteristics of the economic environment of a country.

     As hyperinflationary conditions in Turkey no longer existed starting from 1
     January 2006, New Turkish Lira ("TRY") has been treated as a more stable
     currency since that time and the financial statements of the Company and
     those of the subsidiaries located in Turkey and Turkish Republic of
     Northern Cyprus prepared in accordance with IFRS are not required to be
     adjusted for hyperinflationary accounting.

     The accounting policies set out below have been applied consistently to all
     periods presented in these consolidated interim financial statements and in
     preparing an opening IFRS balance sheet at 1 January 2005 for the purposes
     of the transition to IFRSs.

NOTES TO THE CONSOLIDATED INTERIM FINANCIAL STATEMENTS
As at and for the three months ended 31 March 2006
(Amounts expressed in thousands of US dollars unless otherwise indicated except
share amounts)
--------------------------------------------------------------------------------


1.   Significant accounting policies and operations (continued)

(c)  Basis of consolidation

(i)  Subsidiaries

     Subsidiaries are entities controlled by the Company. Control exists when
     the Company has the power, directly or indirectly, to govern the financial
     and operating policies of an entity so as to obtain benefits from its
     activities. In assessing control, potential voting rights that presently
     are exercisable or convertible are taken into account. The interim
     financial statements of subsidiaries are included in the consolidated
     interim financial statements from the date that control commences until the
     date that control ceases.

(ii) Associates

     Associates are those entities in which the Company has significant
     influence, but not control, over the financial and operating policies. The
     consolidated interim financial statements include the Group's share of the
     total recognised gains and losses of associates on an equity accounted
     basis, from the date that significant influence commences until the date
     that significant influence ceases. When the Group's share of losses exceeds
     its interest in an associate, the Group's carrying amount is reduced to nil
     and recognition of further losses is discontinued except to the extent that
     the Group has incurred legal or constructive obligations or made payments
     on behalf of an associate. The Group's only associate, Fintur Holdings B.V.
     ("Fintur") is accounted under the equity method.

(iii) Transactions eliminated on consolidation

     Intragroup balances and any unrealised gains and losses or income and
     expenses arising from intragroup transactions, are eliminated in preparing
     the consolidated interim financial statements. Unrealised gains arising
     from transactions with associates are eliminated to the extent of the
     Group's interest in the entity. Unrealised losses are eliminated in the
     same way as unrealised gains, but only to the extent that there is no
     evidence of impairment.

(d)  Foreign currency

(i)  Foreign currency transactions

     Transactions in foreign currencies are translated at the foreign exchange
     rate ruling at the date of the transaction. Monetary assets and liabilities
     denominated in foreign currencies at the balance sheet date are translated
     to the functional currency, TRY, at the foreign exchange rate ruling at
     that date. Foreign exchange differences arising on translation of foreign
     currency transactions are recognised in the income statement. Non monetary
     assets and liabilities that are measured in terms of historical cost in a
     foreign currency are translated using the exchange rate at the date of the
     transaction. Non-monetary assets and liabilities denominated in foreign
     currencies that are stated at fair value are translated to TRY at foreign
     exchange rate ruling at the dates the fair value was determined.

(ii) Financial statements of foreign operations

     The assets and liabilities of foreign operations, including fair value
     adjustments arising on consolidation, are translated to US Dollars at
     foreign exchange rates ruling at the balance sheet date. The revenues and
     expenses of foreign operations are translated to US Dollars at rates
     approximating to the foreign exchange rates ruling at the dates of the
     transactions. Foreign exchange differences arising on retranslation are
     recognized directly in a separate component of equity.

--------------------------------------------------------------------------------


1.   Significant accounting policies and operations (continued)

(d)  Foreign currency (continued)

(iii) Translation from functional to presentation currency

     Items included in the financial statements of each company are measured
     using the currency of the primary economic environment in which the
     entities operate, normally, under their local currencies.

     The consolidated interim financial statements are presented in US Dollars,
     which is the presentation currency of the Group. The Group uses US Dollars
     as the presentation currency for the convenience of investor and analyst
     community.

     Assets and liabilities for each balance sheet presented (including
     comparatives) are translated to US Dollars at the foreign exchange rates at
     the balance sheet date. Revenues and expenses for each income statement
     (including comparatives) in hyperinflationary economies are translated to
     US Dollars at foreign exchange rates at the balance sheet date. Revenues
     and expenses for each income statement (including comparatives) in
     non-hyperinflationary economies are translated to US Dollars at rates
     approximating to the foreign exchange rates at the dates of the
     transactions.

     Foreign exchange differences arising on retranslation are recognised
     directly in a separate component of equity.

     Prior to translating the financial statements in hyperinflationary
     economies, the financial statements, including comparatives, are restated
     to account for changes in the general purchasing power of the local
     currency. The resulting gain on net monetary position is recognized as a
     separate component of the income statement. The restatement is based on
     relevant price indices at the balance sheet date.

(iv) Net investment in foreign operations

     Exchanges differences arising from the translation of the net investment in
     foreign operations are taken to translation reserve. They are released into
     the income statement upon disposal.

(e)  Derivative financial instruments

     The Group uses derivative financial instruments to hedge its exposure to
     foreign exchange risk arising from operational, financing and investment
     activities. In accordance with its treasury policy, the Group engages in
     forward and option contracts. However, these derivatives do not qualify for
     hedge accounting and are accounted for as trading instruments.

     Derivative financial instruments are recognised initially at cost.
     Subsequent to initial recognition, derivative financial instruments are
     stated at fair value. The gain or loss on remeasurement to fair value is
     recognised immediately in income statement.

     The fair value of forward exchange contracts and options is their quoted
     market price at the balance sheet date, being the present value of the
     quoted forward prices and fair values based on option pricing models for
     option contracts.

(f)  Property, plant and equipment

(i)  Owned assets

     Items of property, plant and equipment are stated at cost adjusted for the
     effects of inflation during the hyperinflationary period lasted by 31
     December 2005 less accumulated depreciation (see below) and impairment
     losses (see accounting policy l).

     Where parts of an item of property, plant and equipment have different
     useful lives, they are accounted for as separate items of property, plant
     and equipment.

1.   Significant accounting policies and operations (continued)

(f)  Property, plant and equipment (continued)

(ii) Leased assets

     Leases in terms of which the Group assumes substantially all the risks and
     rewards of ownership are classified as finance leases. The owner-occupied
     property acquired by way of finance lease is stated at an amount equal to
     the lower of its fair value and the present value of the minimum lease
     payments at inception of the lease, less accumulated depreciation (see
     below) and impairment losses (see accounting policy l). The property held
     under finance leases and leased out under operating lease is classified as
     investment property and stated at the fair value model. Lease liabilities
     are reduced by repayments of principal, while the interest charge component
     of the lease payment is charged to the income statement. Property held
     under operating leases that would otherwise meet the definition of
     investment property may be classified as investment property on a
     property-by-property basis.

(iii) Subsequent costs

     The Group recognises in the carrying amount of an item of property, plant
     and equipment the cost of replacing part of such an item when that cost is
     incurred if it is probable that the future economic benefits embodied with
     the item will flow to the Group and the cost of the item can be measured
     reliably. All other costs are recognised in the income statement as an
     expense as incurred. There is no interest capitalization on property, plant
     and equipment as at 31 March 2006 and 2005.

(iv) Depreciation

     Depreciation is charged to the income statement on a straight-line basis
     over the estimated useful lives of each part of an item of property, plant
     and equipment. Land is not depreciated. The estimated useful lives are as
     follows:

            Buildings                                        25 - 50 years
            Network infrastructure                            5 - 8 years
            Equipment, fixtures and fittings                  4 - 5 years
            Motor vehicles                                    4 - 5 years
            Leasehold improvements                                5 years

(g)  Intangible assets

     Intangible assets are acquired by the Group are stated at cost adjusted for
     the effects of inflation during the hyperinflationary period that lasted by
     31 December 2005 less accumulated amortisation (see below) and impairment
     losses (see accounting policy l).

     Expenditure on internally generated goodwill and brands is recognised in
     the income statement as an expense as incurred.

(i)  Subsequent expenditure

     Subsequent expenditure on capitalised intangible assets is capitalised only
     when it increases the future economic benefits embodied in the specific
     asset to which it relates. All other expenditure is expensed as incurred.

1.   Significant accounting policies and operations (continued)

(g)  Intangible assets (continued)

(ii) Amortization

     Amortisation is charged to the income statement on a straight line basis
     over the estimated useful lives of intangible assets unless such lives are
     indefinite. Goodwill and intangible assets with an indefinite useful life
     are systematically tested for impairment at each balance sheet date. Other
     intangible assets are amortised from the date they are available for use.
     The estimated useful lives are as follows:

           Computer software                                  3 - 8  years
           GSM and other telecommunications license           4 - 25 years
           Transmission lines                                     10 years
           Central betting system operating right             4 - 5  years
           Customer base                                          2  years

(h)  Investments

     Financial instruments held for trading are classified as current assets and
     are stated at fair value, with any resultant gain or loss recognised in the
     income statement.

     Where the Group has the positive intent and ability to hold government
     bonds and treasury bills to maturity, they are stated at amortised cost
     less impairment losses (see accounting policy l).

     Other financial instruments held by the Group are classified as being
     available-for-sale and are stated at fair value, with any resultant gain or
     loss being recognised directly in equity, except for impairment losses and,
     in the case of monetary items such as debt securities, foreign exchange
     gains and losses which are recognized in the income statement. When these
     investments are derecognised, the cumulative gain or loss previously
     recognised directly in equity is recognised in the income statement. Where
     these investments are interest-bearing, interest calculated using the
     effective interest method is recognised in the income statement.

     The fair value of financial instruments classified as held for trading and
     available-for-sale is their quoted bid price at the balance sheet date.

     Financial instruments classified as held for trading or available-for-sale
     investments are recognised (derecognised) by the Group on the date it
     commits to purchase (sell) the investments. Securities held-to-maturity are
     recognised (derecognised) on the day they are transferred to/by the Group.

     Held to maturity, available for sale and held for trading securities at 31
     March 2006, consist of government bonds, foreign investment equity funds
     and the Company's equity investments in certain entities (see Note 9).

(i)  Trade and other receivables

     Trade and other receivables are stated at their amortized cost less
     impairment losses.

(j)  Inventories

     Inventories are stated at the lower of cost and net realisable value. Net
     realisable value is the estimated selling price in the ordinary course of
     business, less the estimated costs of completion and selling expenses. The
     cost of inventory is determined using the weighted average method and
     includes expenditure incurred in acquiring the inventories and bringing
     them to their existing location and condition. At 31 March 2006 and 31
     December 2005, inventories consisted of simcards and scratch cards
     (finished goods).

1.   Significant accounting policies and operations (continued)

(k)  Cash and cash equivalents

     Cash and cash equivalents comprise cash balances and bank deposits. Bank
     overdrafts that are repayable on demand and form an integral part of the
     Group's cash management are included as a component of cash and cash
     equivalents for the purpose of the statement of cash flows.

(l)  Impairment

     The carrying amounts of the Group's assets other than inventories (see
     accounting policy j), and deferred tax assets (see accounting policy r) are
     reviewed at each balance sheet date to determine whether there is any
     indication of impairment. If any such indication exists, the asset's
     recoverable amount is estimated.

     For intangible assets that are not yet available for use, the recoverable
     amount is estimated at each balance sheet date.

     An impairment loss is recognised whenever the carrying amount of an asset
     or its cash generating unit exceeds its recoverable amount. Impairment
     losses are recognised in the income statement.

     Goodwill was tested for impairment at 1 January 2005, the date of
     transition to IFRS, even through no indication of impairment existed. As at
     31 December 2005, the Company provided impairment for its only goodwill
     amounting to $803 with respect to acquisition of the remaining 30% shares
     of Mapco Internet ve Iletisim Hizmetleri Pazarlama AS ("Mapco") in June
     2003.

     When a decline in the fair value of an available-for-sale financial asset
     has been recognised directly in equity and there is objective evidence that
     the asset is impaired, the cumulative loss that had been recognised
     directly in equity is recognised in the income statement even though the
     financial asset has not been derecognised. The amount of the cumulative
     loss that is recognised in the income statement is the difference between
     the acquisition cost and current fair value, less any impairment loss on
     that financial asset previously recognised in the income statement.

     (i) Calculation of recoverable amount

     The recoverable amount of the Group's investments in held to maturity
     securities and receivables carried at amortised cost is calculated as the
     present value of estimated future cash flows, discounted at the original
     effective interest rate. Receivables with a short duration are not
     discounted.

     The recoverable amount of other assets is the greater of their net selling
     price and value in use. In assessing value in use, the estimated future
     cash flows are discounted to their present value using a discount rate that
     reflects current market assessments of the time value of money and the
     risks specific to the asset.

     (ii) Reversal of impairment

     An impairment loss in respect of a held-to-maturity security or receivable
     carried at amortised cost is reversed if the subsequent increase in
     recoverable amount can be related objectively to an event occurring after
     the impairment loss was recognised.

     An impairment loss in respect of an investment in an equity instrument
     classified as available for sale is not reversed through the income
     statement. If the fair value of a debt instrument classified as
     available-for-sale increases and the increase can be objectively related to
     an event occurring after the impairment loss was recognised in the income
     statement, the impairment loss shall be reversed, with the amount of the
     reversal recognised in the income statement.

     An impairment loss in respect of goodwill is not reversed.

1.   Significant accounting policies and operations (continued)

(l)  Impairment (continued)

     In respect of other assets, an impairment loss is reversed if there has
     been a change in the estimates used to determine the recoverable amount.

     An impairment loss is reversed only to the extent that the asset's carrying
     amount does not exceed the carrying amount that would have been determined,
     net of depreciation or amortisation, if no impairment loss had been
     recognised.

(m)  Share capital

     (i) Share Capital

     Common stock of the Company represented 1,854,887,341 authorized, issued
     and fully paid shares with a par value of TRY 1 each as at 31 March 2006.
     The Company has no preference share capital as at 31 March 2006.

     (ii) Repurchase of share capital

     When share capital recognized as equity is repurchased, the amount of the
     consideration paid, including directly attributable costs, is recognized as
     a change in equity. Repurchased shares are classified as treasury shares
     and presented as a deduction from total equity.

     (iii) Dividends

     Dividends are assumed as a liability in the period in which they are
     declared.

(n)  Interest-bearing borrowings

     Interest-bearing borrowings are recognised initially at fair value less
     attributable transaction costs. Subsequent to initial recognition,
     interest-bearing borrowings are stated at amortised cost with any
     difference between cost and redemption value being recognised in the income
     statement over the period of the borrowings on an effective interest basis.

(o)  Employee benefits

     (i) Retirement pay liability

     In accordance with existing labor law in Turkey, the Company and its
     subsidiaries in Turkey are required to make lump-sum payments to employees
     who have completed one year of service and whose employment is terminated
     without cause, or who retire, are called up for military service or die.
     Such payments are calculated on the basis of 30 days' pay maximum TRY 1,771
     as at 31 March 2006 (31 December 2005: TRY 1,727) per year of employment at
     the rate of pay applicable at the date of retirement or termination.
     Reserve for retirement pay is computed and reflected in the consolidated
     interim financial statements on a current basis. The reserve has been
     calculated by estimating the present value of future probable obligation of
     the Group arising from the retirement of the employees. The calculation was
     based upon the retirement pay ceiling announced by the government.

     (ii) Defined contribution plans

     Obligations for contributions to defined contribution plans are recognised
     as an expense in the income statement as incurred. The Company initiated a
     defined contribution retirement plan for all eligible employees during
     2005. Besides, Inteltek Internet Teknoloji Yatirim ve Danismanlik Ticaret
     AS (Inteltek), another consolidated subsidiary, initiated a defined
     contribution retirement plan for all eligible employees during 2006. The
     assets of the plan are held separately from the financial statements of the
     Group. The Company and Inteltek are required to contribute a specified
     percentage of payroll costs to the retirement benefit scheme to fund the
     benefits. The only obligation of the Company and Inteltek with respect to
     the retirement plan is to make the specified contributions.

1.   Significant accounting policies and operations (continued)

(p)  Provisions

     A provision is recognised in the balance sheet when the Group has a present
     legal or constructive obligation as a result of a past event, and it is
     probable that an outflow of economic benefits will be required to settle
     the obligation. If the effect is material, provisions are determined by
     discounting the expected future cash flows at a pre-tax rate that reflects
     current market assessments of the time value of money and, where
     appropriate, the risks specific to the liability.

(q)  Trade and other payables

     Trade payables are initially measured at fair value, and are subsequently
     measured at amortised cost, using the effective interest rate method.

(r)  Revenue

     Communication fees include all types of postpaid revenues from incoming and
     outgoing calls, additional services and prepaid revenues. Communication
     fees are recognized at the time the services are rendered.

     With respect to prepaid revenues, the Group generally collects cash in
     advance by selling scratch cards to distributors. In such cases, the Group
     does not recognize revenue until the subscribers use the telecommunications
     services. Instead, deferred revenue is recorded under current liabilities.

     Commission fees mainly comprised of net takings earned to a maximum of 12%
     of gross takings, as a head agent of fixed odds betting games and 4.3%
     commission recognized based on the para-mutual and fixed odds betting games
     operated on Central Betting System. Commission revenues are recognized at
     the time all the services related with the games are fully rendered. Under
     the head agency agreement, Inteltek is obliged to undertake any excess
     payout, which is presented on net basis with the commission fees.

     Monthly fixed fees represent a fixed amount charged to postpaid subscribers
     on a monthly basis without regard to the level of usage. Fixed fees are
     recognized on a monthly basis when billed.

     Simcard sales are recognized upon initial entry of a new subscriber into
     the GSM system only to the extent of direct costs. Excess simcard and
     prepaid simcard sales, if any, are deferred and amortized over the
     estimated effective subscriber life.

     Call center revenues are recognized at the time the services are rendered.

(s)  Expenses

(i)  Operating lease payments

     Payments made under operating leases are recognized in the income statement
     on a straight-line basis over the term of the lease. Lease incentives
     received are recognized in the income statement as an integral part of the
     total lease expense.

(ii) Finance lease payments

     Minimum lease payments are apportioned between the finance charge and the
     reduction of the outstanding liability. The finance charge is allocated to
     each period during the lease term so as to produce a constant periodic rate
     of interest on the remaining balance of the liability.

1.   Significant accounting policies and operations (continued)

(s)  Expenses (continued)

(iii) Net financing costs

     Net financing costs comprise interest payable on borrowings calculated
     using the effective interest rate method, interest receivable on funds
     invested, foreign exchange gains and losses and gains and losses on
     derivative financial instruments that are recognized in the income
     statement.

     Interest income and expense is recognised in the income statement as it
     accrues, using the effective interest method. The interest expense
     component of finance lease payments is recognised in the income statement
     using the effective interest rate method.

(t)  Transactions with related parties

     A related party is essentially any party that controls or can significantly
     influence the financial or operating decisions of the Group to the extent
     that the Group may be prevented from fully pursuing its own interests. For
     reporting purposes, investee companies and their shareholders, key
     management personnel, shareholders of the Group and the companies that the
     shareholders have a relationship with are considered to be related parties.

(u)  Income taxes

     Income tax on the income statement for the periods presented comprises
     current and deferred tax. Income tax is recognized in the income statement
     except to the extent that it relates to items recognized directly in
     equity, in which case it is recognized in equity.

     Current tax is the expected tax payable on the taxable income for the year,
     using tax rates enacted or substantially enacted at the balance sheet date,
     and any adjustment to tax payable in respect of previous years.

     Deferred tax is provided using the balance sheet liability method,
     providing for temporary differences between the carrying amounts of assets
     and liabilities for financial reporting purposes and the amounts used for
     taxation purposes. The following temporary differences are not provided
     for: goodwill not deductible for tax purposes, the initial recognition of
     assets or liabilities that affect neither accounting nor taxable profit and
     differences relating to investments in subsidiaries to the extent that they
     will probably not reverse in the foreseeable future. The amount of deferred
     tax provided is based on the expected manner of realization or settlement
     of the carrying amount of assets and liabilities, using tax rates enacted
     or substantively enacted at the balance sheet date.

     A deferred tax asset is recognized only to the extent that it is probable
     that future taxable profits will be available against which the asset can
     be utilized. Deferred tax assets are reduced to the extent that it is no
     longer probable that the related tax benefit will be realized.

     Additional income taxes that arise from the distribution of dividends are
     recognized at the same time as the liability to pay the related dividend.

     Information as to the calculation of income tax on the income statement for
     the interim periods presented is included in Note 4.

     The Company forecasts taxable income in 2006 and onwards and has generated
     taxable income for several years. Currently, economic and political
     situation in Turkey became more stable and there are positive expectations
     about the near term future. Further, there are positive developments
     regarding the Turkey's membership to the European Union. On 3 October 2005,
     the member states of European Union decided to start membership discussions
     with Turkey, a decision that is expected to have certain political and
     economic benefits for Turkey in near future. Management believes that these
     developments provide management a better visibility about the near term
     future. As a result, as at 31 March 2006, management concluded that it is
     probable that the deferred tax assets of $782 were realizable.

10.  Deferred tax assets and liabilities (continued)

     Unrecognised deferred tax assets

     Deferred tax assets have not been recognised in respect of the following
     items:

                                                     31 March       31 December

     Deductible temporary differences                 (21,599)          (13,753)
     Tax credit carry forwards                          4,559             4,508
     Operating loss carry forwards                     49,763            29,515

     Total unrecognised deferred tax assets            32,723            20,270
                                                 =============    ==============

     The deductible temporary differences do not expire under current tax
     legislation. Turkish tax legislation does not allow companies to file tax
     returns on a consolidated basis. Therefore, deferred tax assets have not
     been recognised in respect of these items resulting from certain
     consolidated subsidiaries because it is not probable that future taxable
     profit will be available against which the Company can utilise the benefits
     thereafter.

     As at 31 March 2006 net operating loss carry forwards are as follows;

     Year                                        Amount        Expiration Date

                                              ===============    ===============

     Trade receivables are shown net of impairment losses amounting to $154,612
     as at 31 March 2006 (31 December 2005: $149,209).

     Receivables from Turk Telekom as at 31 March 2006 and 31 December 2005
     represent net amounts that are due from Turk Telekom under the
     Interconnection Agreement. The Interconnection Agreement provides that Turk
     Telekom will pay to the Company for Turk Telekom's fixed-line subscribers'
     calls to GSM subscribers.

11.  Trade receivables and accrued income (continued)

     The accrued service income represents revenues accrued for subscriber calls
     (air-time), which have not been billed. Due to the volume of subscribers,
     there are different billing cycles; accordingly, an accrual is made at each
     period end to accrue revenues for rendered but not yet billed.

     Letters of guarantee received with respect to the accounts and cheques
     receivable are amounting to $46,346 and $48,066 at 31 March 2006 and 31

14.  Capital and reserves (continued)

     Reconciliation of movement in capital and reserves (continued)

     At 31 March 2006, common stock represented 1,854,887,341 (31 December 2005:
     1,854,887,341) authorized, issued and fully paid shares with a par value of
     TRY 1 each. In accordance with the Law No. 5083 with respect to the TRY, on
     9 May 2005, par value of each share is registered to be one TRY.

     In connection with the redenomination of the Turkish Lira and as per the
     related amendments of Turkish Commercial Code, in order to increase the
     nominal value of the shares to TRY 1, 1,000 units of shares, each having a
     nominal value of TRY 0.001 shall be merged and each unit of share having a
     nominal value of TRY 1 shall be issued to represent such shares. The
     Company is currently in the process of merging 1,000 existing ordinary
     shares, each having a nominal value of TRY 0.001 to one ordinary share
     having a nominal value of TRY 1 each. After the share merger which appears
     as a provisional article in the Articles of Association to convert the
     value of each share with a nominal value of TRY 0.001 to TRY 1, all shares
     will have a value of TRY 1. Although the merger process has not been
     finalized, the practical application is to state each share having a
     nominal value of TRY 1 which is consented by Capital Markets Board of
     Turkey ("CMB").

     The holders of shares are entitled to receive dividends as declared and are
     entitled to one vote per share at meetings of the Company.

     Translation reserve

     The translation reserve comprises all foreign exchange differences arising
     from the translation of the interim financial statements of foreign and
     domestic operations from the functional currencies of domestic and foreign
     operations to presentation currency of US Dollars.

     Fair value reserve

     The fair value reserve includes the cumulative net change including
     deferred tax effects in the fair value of available-for-sale investments
     until the investment is derecognized.

     Dividends

     The Company has adopted a dividend policy, which is set out in its
     corporate governance guidance. As adopted, the Company's general dividend
     policy is to pay dividends to shareholders with due regard to trends in the
     Company's operating performance, financial condition and other factors.

     The Board of Directors intends to distribute cash dividends in an amount of
     not less than 50% of the Company's distributable profits based on the
     financial statements prepared in accordance with the accounting principles
     accepted by the CMB, for each fiscal year starting with profits for fiscal
     year 2004. However, the payment of dividends will still be subject to cash
     flow requirements of the Company, compliance with Turkish law and the
     approval of, amendment by, the Board of Directors and the General Assembly
     of Shareholders.

     On 22 March 2006, the Board of Directors of the Company decided to make a
     proposal to the General Assembly for distribution of a total net cash
     dividend of TRY 509,075 (equivalent to $379,143 at 31 March 2006) (which
     constitutes 50% of distributable income per statutory accounts) and
     dividend in the form of bonus issue amounting of TRY 345,113 (equivalent to
     $257,029 at 31 March 2006) for the year ended 31 December 2005. The
     distribution of dividends is subject to approval at the General Assembly
     Meeting, which is planned to be held on 22 May 2006. In the case of
     approval of dividend dstribution in the General Assembly Meeting, dividend
     distribution will start on 29 May 2006.

     term project financing of $390,000. As at 31 March 2006, $302,492 of that
     facility has been utilized and $87,508 was undrawn.

     These financing agreements contain a number of restrictive debt covenants
     applicable to Astelit and Euroasia Telecommunications Holding B.V.
     ("Euroasia"), which may be summarized as follows:

     o   Astelit has to comply with certain financial ratios during the period
         of financing;
     o   Astelit may not pledge any of its assets (including its rights under
         the supply contracts and its rights under the material insurance
         contracts);
     o   Euroasia may not pledge shares owned in Astelit to other parties;
     o   Euroasia may not pledge any loans issued to Astelit;
     o   There are restrictions on disposal of assets by Astelit;
     o   Astelit can not attract financing from parties other than Euroasia and
         Lenders, without the consent of the Lenders;
     o   There are restrictions on finance leasing and supplier financing
         arrangements;
     o   Astelit may not conduct any other business apart from the operation of
         telecommunications services, and business ancillary thereto;
     o   Astelit may not merge with other companies;
     o   There are restrictions on acquisitions of subsidiaries;
     o   There are restrictions on issuance of guarantees by Astelit;
     o   Astelit can not issue any shares for purposes other than receiving
         financial support from current shareholders;
     o   Payment of dividends may only occur once Astelit complies with certain
         financial ratios.

     Besides, as part of the project financing package, a long term junior
     facility up to $150,000 was also finalized with Turkiye Garanti Bankasi AS
     Luxemburg Branch and Akbank TAS Malta Branch. The junior facility is fully
     guaranteed by the Company. As at 31 March 2006, $126,000 of this facility
     has been utilized.

     As at 31 March 2006, only the syndicated long term project financing
     package is secured with asset pledge.

     Based on Astelit's separate interim financial statements as at and for the
     three months ended 31 March 2006, Astelit is in breach of its covenants
     contained in its syndicated long term project financing. The breach of a
     covenant is an event of default and the lenders in the syndicated long term
     project may demand immediate repayment of the outstanding amounts which
     would also trigger the cross-default to and acceleration upon notice of,
     substantially all of the Astelit's borrowings. The breach of the
     consolidated EBITDA is an event of default and in accordance with IFRS, the
     Group has reclassified its total long term debt amounting $382,063
     (including its junior loan) as short term debt payable as at 31 March 2006.
     Astelit requested the facility agent, the senior creditors and the Export
     Credit Agency ("ECA") to waive this requirement in order to make further
     drawings under the syndicated long term financing. The Company and System
     Capital Management Limited ("SCM") have agreed to contribute their
     respective share of approximately $150,000 required by the facility agent
     to Astelit which is subject to the approval of Board of Directors of each
     to be obtained on or before 31 May 2006. As at 10 May 2006, Astelit has
     obtained the waiver letter from the lenders enabling Astelit to draw loans
     under the syndicated long term financing.

21.  Financial instruments

     Exposure to credit, interest rate and currency risks arises in the normal
     course of the Group's business. Derivative financial instruments such as
     forward contracts and options are used to hedge exposure to fluctuations in
     foreign exchange rates. The Group's Treasury is committed to effectively
     manage financial market risks in the context of Group's business strategies
     and with a view to achieve a balance between acceptable levels of risk and
     reward. Within this context, the Group implemented a Treasury Risk
     Management Policy that articulates the recognition, measurement and
     management of interest rate, foreign exchange, credit and liquidity risks
     while monitoring macro economic and financial markets' conditions. In
     addition to this, the Group publishes and periodically updates procedures
     for each type of financial instrument used.

     Credit risk

     Management has a credit policy in place and the exposure to credit risk is
     monitored on an ongoing basis. The Group may require collateral in respect
     of financial assets. Also, the Group may demand letter of guarantees from
     third parties related with certain projects or contracts. The Group may
     also demand certain pledges from counterparties if necessary in return for
     the credit support it gives related to certain financings.

21.  Financial instruments (continued)

     Credit risk (continued)

     Investments are allowed only in liquid securities and mostly with
     counterparties that have a credit rating equal or better than the Company.
     Some of the collection banks have credit ratings that are lower than the
     Company's, or they may not be rated at all, however, policies are in place
     to review the paid-in capital and capital adequacy ratios periodically to
     ensure credit worthiness.

     At the balance sheet date there were no significant concentrations of
     credit risk. The maximum exposure to credit risk is represented by the
     carrying amount of each financial asset, in the balance sheet. The Company
     does not expect any counterparty to fail to meet its obligations.

     Interest rate risk

     As at 31 March 2006, interest on the Company's assets was fixed excluding
     floating rate note holdings. Holdings of Turkish government floating rate
     notes carry a face value of TRY 78,160 with an overnight return of 14.83%.
     Therefore the Company is not exposed to interest rate risk on financial
     assets, apart from floating rate notes, as at 31 March 2006. As at 4 May
     2006, interest on the Company's assets was fixed excluding floating rate
     note holdings. Holdings of Turkish government floating rate notes carry a
     face value of TRY 75,400 with an overnight return of 14.80%.

     The Company has not entered into any type of derivative instrument in order
     to hedge interest rate risk as at 31 March 2006.

     In order to take advantage of market volatility in the local and
     international bond markets, and increase the yield on its free cash, the
     Company has been entering into option transactions to buy or sell Turkish
     sovereign Eurobonds. As at 31 March 2006, company has outstanding options
     in the notional amount of $30,000 for trading purposes. The fair value of
     Eurobond options used as economic hedges of monetary assets and liabilities
     in foreign currencies at 31 March 2006 was $222 (31 December 2005: nil)
     recognized in fair value derivatives. As at 4 May, 2006, company has
     outstanding Eurobond options in the notional amount of $10,000 for trading
     purposes.

     Foreign currency risk

     The Group's functional currency is TRY for operations conducted in Turkey,
     but certain revenues, purchases, operating costs and expenses and resulting
     receivables and payables are denominated in foreign currencies, primarily
     US Dollars, Euros, Swedish Krona and Ukranian Hryvnia.

     To manage the Company's foreign exchange risk more efficiently, in 2006,
     the Company entered into structured forward transactions. As at 31 March
     2006, the Company has outstanding structured forward contracts amounting to
     notional $381,000 to buy US dollar against TRY and notional $150,000 to
     sell US dollar against TRY. Changes in the fair value of forward exchange
     contracts that economically hedge monetary assets and liabilities in
     foreign currencies and for which no hedge accounting is applied are
     recognised in the income statement. The fair value of forward exchange
     contracts used as economic hedges of monetary assets and liabilities in
     foreign currencies at 31 March 2006 was $12,921 (31 December 2005: $267)
     recognised in fair value derivatives. As at 4 May 2006, the Company has
     outstanding structured forward contracts amounting to notional $618,000 to
     buy US dollar against TRY and notional $150,000 to sell US dollar against
     TRY.

     In order to take advantage of market volatility in the foreign exchange
     markets and increase the yield on its free cash, the Company enters into
     option transactions to buy or sell certain currencies, beginning from 2006.
     Option contracts allow the Company to either hedge its exposure or collect
     premiums depending on their types. As at 31 March 2006, the Company has
     bought and sold currency options in the notional amounts of $160,000 and
     (euro)110,000. Changes in the fair value of options that economically hedge
     monetary assets and liabilities in foreign currencies and for which no
     hedge accounting is applied are recognised in the income statement. The
     fair value of currency options used as economic hedges of monetary assets
     and liabilities in foreign currencies at 31 March 2006 was $539 (31
     December 2005: nil) recognised in fair value derivatives. As at 4 May 2006,
     the Company has outstanding foreign currency options in the notional
     amounts of $140,000 and (euro)85,000, respectively.

     Sensitivity analysis

     In managing currency risk, the Company aims to reduce the impact of
     short-term fluctuations on the Company's earnings. Over the longer-term,
     however, permanent changes in foreign exchange and interest rates would
     have an impact on the Company's earnings.

     Sensitivity analysis on the Company's portfolio of structured US dollar
     hedging products has been run. Two extreme case scenarios of 10%
     appreciation and 10% depreciation of TRY/$ exchange rate have been
     included. In case of a 10% depreciation, from a spot rate of 1,3240 on 4
     May 2006, total structured US dollar call transaction size would not be
     effected and total structured US dollar put forward transaction size would
     rise to a total of $300,000 with a total loss effect of $14,624. In the
     case of a 10% appreciation, total structured US dollar call forward
     transaction size would rise to $902,000 with a total loss effect of $80,261
     and total structured US dollar put forward transaction size would not be
     affected.

21.  Financial instruments (continued)

     Fair values

     The following methods and assumptions were used to estimate the fair value
     of each class of financial instruments for which it is practicable to
     estimate that value:

     (a) Other Investments

     Held to maturity securities

     The fair values of government bonds and treasury bills classified as
     held-to-maturity investments are based on quoted market prices at 31 March
     2006.

     Available for sale securities

     The fair values of foreign investment equity funds and government bonds
     classified as available for sale securities are based on both quoted market
     and over the counter market prices at 31 March 2006.

     Held to trading securities

     The fair values of government bonds and treasury bills classified as
     trading securities are based on both quoted market and over the counter
     market prices at 31 March 2006.

     (b) Trade receivable, accrued income and due from related parties

     The carrying amount approximates fair value because of the short maturity
     of those financial assets.

     (c) Other current assets

     The carrying amount approximates fair value because of the short maturity
     of those financial assets. Forward contracts are presented under other
     current assets and current market pricing models are used to estimate their
     fair values.

     (d) Cash and cash equivalents

     The carrying amounts approximate fair value because of the short maturity
     of those instruments.

     (e) Short and long term borrowings

     (i) Borrowings from Akbank, Garanti, Murabaha Syndicated facility, West LB,
     Junior loan, syndicated long term financing facility: The carrying amount
     approximates fair value because the interest rate varies based on the
     London or TRY interbank offered rates.

     (ii) Other short term bank loans and overdrafts: The carrying amount
     approximates fair value because of the short term maturity of those
     instruments.

     (iii) As at 31 December 2005, the estimation of fair value of borrowings
     from ABN Amro NV and Ericsson Credit AB approximates carrying amount
     because the interest rate varies based on the London or Euro interbank
     offered rates.

     (f) Trade payables and due to related parties

     The carrying amount approximates fair value because of the short maturity
     of those financial liabilities.

     requirements, including those regarding the build-out, operation, quality
     and coverage of the Company's GSM network, prohibitions on anti-competitive
     behavior and compliance with national and international GSM standards.
     Failure to meet any requirement in the renewed License, or the occurrence
     of extraordinary unforeseen circumstances, can also result in revocation of
     the renewed License, including the surrender of the GSM network without
     compensation, or limitation of the Company's rights thereunder, or could
     otherwise adversely affect the Company's regulatory status. Certain
     conditions of the renewed License Agreement include the following:

     Coverage: The Company had to attain geographical coverage of 50% and 90% of
     the population of Turkey with certain exceptions within three years and
     five years, respectively, of the License's effective date. The Company has
     completed its related liabilities with respect to coverage as at 31 March

     general GSM services, including free emergency calls and technical
     assistance for subscribers, free call forwarding to police and other public
     emergency services, receiver-optional short messages, video text access,
     fax capability, calling and connected number identification and
     restrictions, call forwarding, call waiting, call hold, multi-party and
     third-party conference calls, billing information and barring of a range of
     outgoing and incoming calls.

     standards determined and updated by the European Telecommunications
     Standards Institute and Secretariat of the GSM MoU. Service quality
     requirements include that call blockage cannot exceed 5% and unsuccessful
     calls cannot exceed 2%.

     Tariffs: Telecommunications Authority sets the initial maximum tariffs in
     TRY and US Dollar. Thereafter, the revised License provides that the
     Telecommunications Authority will adjust the maximum tariffs at most every
     six months or, if necessary, more frequently. The Company is free to set
     its own tariffs up to the maximum tariffs.

     Rights of the Telecommunications Authority, Suspension and Termination:

     The revised License is not transferable without the approval of the
     Telecommunications Authority. In addition, the License Agreement gives the
     Telecommunications Authority certain monitoring rights and access to the
     Company's technical and financial information and allows for inspection
     rights, and gives certain rights to suspend operations under certain
     circumstances. Also, the Company is obliged to submit financial statements,
     contracts and investment plans to the Telecommunications Authority.

     The Telecommunications Authority may suspend the Company's operations for a
     limited or an unlimited period if necessary for the purpose of public
     security and national defence. During period of suspension, the
     Telecommunications Authority may operate the Company's GSM network. The
     Company is entitled to any revenues collected during such period and the
     Licensee's term will be extended by the period of any suspension. The
     revised License may also be terminated upon a bankruptcy ruling against the
     Company or for other license violations, such as operating outside of its
     allocated frequency ranges, and the penalties for such violations can
     include fines, loss of frequency rights, revocation of the license and
     confiscation of the network management centre, the gateway exchanges and
     central subscription system, including related technical equipment,
     immovables and installations essential for the operation of the network.

     harmful electro-magnetic emissions. Licenses require Astelit to inform
     authorities about start / end of operations in one month; about changes in

     the operations of Astelit for a limited or an unlimited period if necessary
     because of the expiration of licenses, upon mutual consent, or in case of
     violation of terms of radio frequencies use. If such a violation is
     determined, Ukrainian Telecommunications Authority notifies Astelit of
     provisions violated and sets deadline for recovery. If the deadline is not
     met, licenses may be terminated.

     CJSC Digital Cellular Communications ("DCC"):

     DCC owns four licenses; three on for local telephone network construction,

     Interconnection Agreements (continued)

     The Regulation is driven largely by a goal to improve the competitive
     environment and ensure that users benefit from telecommunications services
     and infrastructure at a reasonable cost. Under the Regulation, the
     Telecommunications Authority may compel all telecommunications operators to
     accept another operator's request for use of and access to its network. All
     telecommunications operators in Turkey may be required to provide access to
     other operators on the same terms and qualifications provided to their
     shareholders, subsidiaries and affiliates.

     In accordance with the Regulation, the telecommunications providers in
     Turkey (including Turk Telekom), are obliged to renew their interconnection
     agreements within two months following the issuance of the Regulation. The
     Company entered into a new interconnection agreement with Globalstar on 9
     September 2003, and as a result of intervention by the Telecommunications
     Authority, the Company entered into supplemental agreements with Turk
     Telekom on 10 November 2003, Telsim on 21 November 2003, and Globalstar on
     11 December 2003, with amended tariffs and tariff adoption procedures.

     Aycell Haberle(0)me ve Pazarlama Hizmetleri AS ("Aycell"), a new company
     was formed with the name TT&TIM Iletisim Hizmetleri A.S. ("TT&TIM"). The
     interconnection agreement with Is-Tim was renewed with TT&TIM and the
     interconnection agreement with Aycell was cancelled. On 15 October 2004,
     TT&TIM changed its name to AVEA Iletisim Hizmetleri A.S. ("AVEA"). On the
     other hand, the business relationship on interconnection between
     Milleni.com and the Company has been bilaterally terminated as at 21 June
     2004.

     On 21 February 2005, Tellcom Iletisim Hizmetleri AS ("Tellcom") and
     Milleni.com have signed an agreement to provide telecommunications services
     to each other whereby Milleni.com may convey calls to the Company's switch
     and the Company may convey calls to Milleni.com's switch, in both cases,
     for onward transmission to their destinations. In addition, the
     Telecommunications Authority has required operators holding significant
     market power, as well as Turk Telekom, to share certain facilities with
     other operators under certain conditions, and to provide co-location on
     their premises for the equipment of other operators at a reasonable price.
     The Telecommunications Authority may also require telecommunications
     operators to provide number portability, which means allowing users to keep
     the same phone numbers even after they switch from one network to another.

     Under a typical interconnection agreement, each party agrees, among other
     things to permit the interconnection of its network with the Company's
     network to enable calls to be transmitted to, and received from, the GSM
     system operated by each party in accordance with technical specifications
     set out in the interconnection agreement. Typical interconnection
     agreements also establish understandings between the parties relating to a
     number of key operational areas, including call traffic management, quality
     and performance standards, interconnection interfaces and other technical,
     operational and procedural aspects of interconnection. The Company's
     interconnection agreements usually provide that each party will assume
     responsibility for the safe operation of its own network. Each party is
     also typically responsible for ensuring that its network does not endanger
     the safety or health of employees, contractors, agents or customers of the
     other party or damage interfere with or cause any deterioration in the
     operation of the other party's network.

     Interconnection agreements also specify the amount of the payments that
     each party will make to the other for traffic originated on one network but
     switched to the other. These payments vary by contract, and in same cases,
     may require the Company to pay the counterparty less, the same amount, or a
     greater amount per minute, for traffic originating on the Company's network
     but switching to the counterparty's network, then it receives for a similar
     call originating on another network and switched to the Company's network.

     License Agreements (continued)

     There are no minimum payment obligations under the interconnection
     agreements; however, failure to carry the counterparty's traffic may expose
     the Company to financial and other penalties or loss of interconnection
     privileges for its own traffic. The Company and other operators have
     entered into interconnection agreements which set out the terms and
     conditions regarding the price terms as well as periodical revision of such
     terms. However, revisions of the pricing terms of the interconnection
     agreements have been pending as the Company has not been able to agree on
     the pricing terms with other operators through discussions. As per the
     Access and Interconnection Regulation, the issue has been escalated to the
     Telecommunications Authority by Turk Telekom, Telsim and Avea. Meanwhile,
     the Telecommunications Authority issued reference interconnection rates
     during the fourth quarter of 2004, which indicate pricing terms.
     Consequently, on 10 August 2005, the Telecommunications Authority issued a
     `temporary interconnection price schedule' for the interconnection between
     Turk Telekom and the Company which are in line with the reference tariff
     structure defined by the Telecommunications Authority during the fourth
     quarter of 2004. The Telecommunications Authority is expected to issue a
     final price structure.

     Legal Proceedings

     The Group is involved in various claims and legal actions arising in the
     ordinary course of business described below.

     Dispute on VAT on Ongoing License Fee

     Starting from June 2003, the Company has begun to make payments for VAT on
     ongoing license fees with reservations and commenced a lawsuit against the
     Tax Office for the related period. On 31 December 2003, the Tax Court
     decided that the Company would not have to pay VAT on ongoing license fee
     from February 2004 onwards. The Tax Office has appealed this decision.
     Based on the management and legal counsel's opinion, the Company has not
     provided any accrual related with this dispute in its consolidated interim
     financial statements as at and for the three months ended 31 March 2006.

     Dispute on Turk Telekom Transmission Lines Leases

     Effective from 1 July 2000, Turk Telekom annulled the discount of 60% that
     it provided to the Company based on its regular ratio, which had been
     provided for several years, and, at the same time, Turk Telekom started to
     provide a discount of 25% being subject to certain conditions. The Company
     filed a lawsuit against Turk Telekom for the application of the agreed 60%
     discount. However, on 30 July 2001, the Company had been notified that the
     court of appeal upheld the decision made by the commercial court allowing
     Turk Telekom to terminate the 60% discount. Accordingly, the Company paid
     and continues to pay transmission fees to Turk Telekom based on the 25%
     discount. Although Turk Telekom did not charge any interest on late
     payments at the time of such payments, the Company recorded an accrual
     amounting to a nominal amount of TRY 3,022 ($2,251 as at 31 March 2006) for
     possible interest charges as at 31 December 2000. On 9 May 2002, Turk
     Telekom requested an interest amounting to a nominal amount of TRY 30,068
     (equivalent to $22,394 as at 31 March 2006). The Company did not agree with
     the Turk Telekom's interest calculation and, accordingly, obtained an
     injunction from the commercial court to prevent Turk Telekom from
     collecting any amounts relating to this interest charge. Also, the Company
     initiated a lawsuit against Turk Telekom on the legality of such interest.
     The case is still pending. As at 31 March 2006, the Company recorded a
     provision of nominal amount of TRY 13,296 (equivalent to $9,902 as at 31
     March 2006) because its management and legal counsel believe that this is
     the most likely outcome in accordance with the relevant provisions of the
     Interconnection Agreement.

     Legal Proceedings (continued)

     Dispute on National Roaming Agreement

     During the third quarter of 2001, the Company was approached by Is-Tim to
     negotiate a national roaming agreement. These negotiations did not result
     in a mutual agreement. Therefore, the discussions continuing under the
     supervision of the Telecommunications Authority has been subject to several
     lawsuits. The cases are still pending.

     On 9 June 2003, the Turkish Competition Board (the "Competition Board")
     decided that the Company abused its dominant position by refusing to enter
     into a national roaming agreement with Is-Tim, and fined the Company by
     nominal amount of approximately TRY 21,822 (equivalent to $16,252 at 31
     March 2006). On 28 March 2006, Danistay cancelled the Competition Board's
     decision.

     On 10 December 2004, Tax Office requested nominal amount of approximately
     TRY 21,822 (equivalent to $16,252 at 31 March 2006) regarding the
     Competition Board decision. On 25 November 2005, the Administrative Court
     decided the cancellation of the aforementioned payment order. Both the
     Competition Board and Tax Office have appealed the decision. Based on its
     management and legal counsel's opinion, the Company has not recorded any
     accrual for Competition Board's decision.

     Additionally, the Telecommunications Authority decided that the Company has
     not complied with its responsibility under Turkish regulations to provide
     national roaming and fined the Company by nominal amount of approximately
     TRY 21,822 (equivalent to $16,252 at 31 March 2006). On 7 April 2004, the
     Company made the related payment. On 3 January 2005 Telecommunications
     Authority paid back nominal amount of TRY 21,822 (equivalent to $16,252 at
     31 March 2006). On 13 December 2005, Danistay decided the cancellation of
     the administrative fine but rejected the Company's request for cancellation
     of the regulation on procedures and policies with respect to national
     roaming. Based on its management and legal counsel's opinion, the Company
     recorded income amounting to nominal amount of TRY 21,822 (equivalent to
     $16,252 at 31 March 2006) in its consolidated interim financial statements
     as at and for the year ended 31 December 2004.

     If the Company is forced to enter a national roaming agreement on terms and
     conditions that do not provide an adequate return on its investment in its
     GSM network, its financial position, results of operations and cash flows
     could be adversely affected.

     Investigation of the Turkish Competition Board

     The Competition Board commenced an investigation of business dealings
     between the Company and KVK Teknoloji, in October 1999. The Competition
     Board decided that the Company disrupted the competitive environment
     through an abuse of dominant position in the Turkish mobile market and
     infringements of certain provisions of the Law on the Protection of
     Competition. As a result, the Company was fined by nominal amount of
     approximately TRY 6,973 (equivalent to $5,193 as at 31 March 2006) and was
     enjoined to cease these infringements. The Company initiated a lawsuit
     before Danistay for the injunction and cancellation of the decision. On 15
     November 2005, Danistay cancelled the Competition Board's decision on the
     ground that Competition Board infringed the procedural rules governing the
     investigation process. The Company has accrued nominal amount of TRY 6,973
     (equivalent to $5,193 as at 31 March 2006) on its consolidated interim
     financial statements as at 31 March 2006.

     Legal Proceedings (continued)

     Investigation of the Turkish Competition Board (continued)

     After the cancellation of the Competition Board's decision, the Competition
     Board has given the same decision again on 29 December 2005. On 10 March
     2006, the Company initiated a lawsuit before Danistay for the injunction
     and cancellation of the decision. The case is still pending. Based on its
     management and legal counsel's opinion, the Company continues to accrue for
     TRY 6,973 (equivalent to $5,193 as at 31 March 2006) on its consolidated
     interim financial statements as at 31 March 2006.

     Dispute on Collection of Frequency Usage Fees

     On 21 May 1998, the Company entered into a protocol with the Wireless
     Communications General Directorate (the "Directorate") regarding the
     application of the governing provisions of the Wireless Law No. 2813 to the
     administration of its GSM mobile phone network. Under this protocol, the
     Company is to collect frequency usage fees, which are calculated by the
     Directorate, from the taxpayers using mobile phones on behalf of the
     Directorate, and to pay the levied tax to the Directorate. In 2001, the
     Directorate's power, including all of its rights and obligations, was
     transferred to the Telecommunications Authority. On 22 March 2002, as a
     consequence of the impossibility in fact and at law of collecting such tax
     from its prepaid subscribers, the Company filed a lawsuit requesting
     cancellation of the protocols obligating it to collect the frequency usage
     fees from the prepaid subscribers and to pay it to the Telecommunications
     Authority. After respective legal procedures, on 20 April 2004, the Company
     paid nominal amount of TRY 145,644 (equivalent to $108,471 at 31 March
     2006) for the frequency usage fees of 2002 including interest through that
     date with reservation. The court rejected the Company's request and decided
     that there should be no further judgment on this issue since the frequency
     usage fees of 2002 are paid. Both the Company and Telecommunications
     Authority have appealed this decision. Supreme Court will review this
     lawsuit.

     Investigation of the Telecommunications Authority on International Voice
     Traffic

     In May 2003, the Company was informed that the Telecommunications Authority
     had initiated an investigation against the Company claiming that the
     Company has violated Turkish laws by carrying some of its international
     voice traffic through an operator other than Turk Telekom. The Company is
     disputing whether Turk Telekom should be the sole carrier of international
     voice traffic. On 5 March 2004, the Telecommunications Authority fined the
     Company by nominal amount of approximately TRY 31,731 (equivalent to
     $23,632 at 31 March 2006). On 9 April 2004, the Company made the respective
     payment. With respect to the Danistay's injunction on 26 January 2005,
     Telecommunications Authority paid back the nominal amount.
     Telecommunications Authority appealed this decision. Case is still pending.
     Based on its management and legal counsel's opinion, the Company has
     recorded income amounting to nominal amount of TRY 31,731 (equivalent to
     $23,632 at 31 March 2006) in the consolidated financial statements as at
     and for the year ended 31 December 2004.

     On 2 March 2005, Turk Telekom notified the Company that, the Company has
     damaged Turk Telekom because of the interconnection agreement signed with
     Milleni.com. Accordingly, Turk Telekom requested the Company to pay nominal
     amount of TRY 219,148 (equivalent to $163,214 as at 31 March 2006) of
     principal and nominal amount of TRY 178,364 (equivalent to $132,840 as at
     31 March 2006) of interest, which make a sum of nominal amount of TRY
     397,515 (equivalent to $296,056 as at 31 March 2006) until 7 March 2005.
     Related case is still pending. However, on 13 December 2005, Danistay
     rejected the request of Turk Telekom regarding the cancellation of the
     interconnection agreement between Milleni.com and the Company. Management
     and legal counsel believe that the aforementioned request has no legal
     basis. At this point, regarding this litigation it is premature to estimate
     its potential outcome, if any.

     Investigation of the Telecommunications Authority on International Voice
     Traffic (continued)

     Based on its management and legal counsel's opinion, the Company has not
     provided any accruals with respect to this matter in its consolidated
     interim financial statements as at 31 March 2006.

     Investigation of the Telecommunications Authority on Frequency Fee Payments

     On 23 October 2003, the Telecommunications Authority fined the Company,
     claiming that the Company has made inadequate annual frequency usage fee
     payments by notifying its subscriber numbers less than the actual. The
     Telecommunications Authority requested nominal amount of TRY 16,005
     (equivalent to $11,920 as at 31 March 2006) for principal, an interest
     charge of nominal amount of TRY 10,761 (equivalent to $8,014 as at 31 March
     2006) and a penalty of nominal amount of TRY 63,463 (equivalent to $47,265
     as at 31 March 2006). Management and legal counsel believe that the
     Telecommunications Authority's decision is due to a misinterpretation of
     the applicable regulations. On 20 February 2004, the Company initiated
     legal proceedings for the annulment of the decision. On 16 April 2004, the
     Company paid nominal amount of TRY 103,740 (equivalent to $77,262 as at 31
     March 2006) including interest through that date regarding the
     Telecommunication Authority's claim. Danistay rejected the Company's
     request of injunction. On 12 October 2005, the Tax Office sent a payment
     order amounting to nominal amount of TRY 63,463 (equivalent to $47,265 as
     at 31 March 2006) which was paid by the Company previously. On 8 November
     2005, the Company initiated another lawsuit before the Administrative Court
     against the Tax Office requesting an injunction and cancellation of the
     payment order.

     Dispute on Special Transaction Taxation Regarding Prepaid Card Sales

     On 18 September 2003, the Ministry of Finance issued a report stating that
     by applying discounts for prepaid card sales for the period between June -
     December 2002, the Company calculated the special transaction tax on
     post-discounted amount. Pursuant to this report, the Tax Office delivered
     to the Company a notice, asserting deficiencies in special transaction tax
     declarations and requesting a special transaction tax payment amounting to
     nominal amount of TRY 6,993 (equivalent to $5,208 at 31 March 2006) and a
     tax penalty of nominal amount of TRY 9,875 (equivalent to $7,355 at 31
     March 2006). The case is still pending. Management and legal counsel
     believe that the Company will prevail in this matter. Accordingly, the
     Company has not provided any accruals with respect to this matter in its
     consolidated interim financial statements as at 31 March 2006.

     Disputes on annulment of fixed odd betting tender related to establishment
     and operation of risk management center head agency

     Reklam Departmani Basin Yayin Proje Yapim Danismanlik ve Ticaret Limited
     Sirketi ("Reklam Departmani") commenced a lawsuit against the Spor Toto
     Teskilat Mudurlugu. In the lawsuit, Reklam Departmani claimed for the
     annulment of fixed odd betting tender related to the establishment and
     operation of risk management center and acting as head agency. The Company
     is not a party to the lawsuit but Inteltek's operations may be affected by
     the court's decision. Accordingly, the Company requested to join the case.
     Danistay accepted the request of Reklam Departmani with respect to the
     appeal. On 17 February 2006, Spor Toto has applied for the correction of
     this decision. The case is still pending. Besides, the request of Inteltek
     to join the case was rejected by Danistay on 6 March 2006 and Inteltek has
     appealed this decision. Legal counsel and management believe that it is not
     practicable to issue an opinion on the conclusion of the case. The Company
     has not provided any accruals with respect to this matter in its
     consolidated interim financial statements as at 31 March 2006.

     but Inteltek's operations may be affected by the court's decision.
     Accordingly, the Company joined the case. Danistay accepted the request of
     Gtech regarding the appeal. Inteltek has applied for the correction of
     decision on 9 February 2006. Gtech commenced also another lawsuit against
     Genclik ve Spor Genel Mudurluou for the cancellation of the fixed odd
     betting contract signed in the same tender. The Ankara 4th Administrative
     Court rejected the request of Gtech. Gtech appealed this decision and
     Danistay also rejected the request. The cases are still pending. Legal
     counsel believes that it is not practicable to issue an opinion on the

     rejected the request. The case is still pending.

     Dispute with Spor Toto Teskilat Mudurlugu

     On 15 April 2005, Spor Toto Teskilat Mudurlugu, regulatory authority of
     sports betting in Turkey, notified Inteltek that Inteltek is obliged to pay
     nominal amount of TRY 1,434 (equivalent to $1,068 at 31 March 2006)
     including 5% interest charge, with the claim of the inadequacy of the
     system software, failure to spot dealer sales on a live basis and lack of
     control mechanisms and cause for the non-collection of a certain portion of
     turnover from dealers. On 2 November 2005, Spor Toto Teskilat Mudurlugu
     sent a second letter to Inteltek that Inteltek is obliged to pay nominal
     amount of TRY 1,711 (equivalent to $1,274 at 31 March 2006) of uncollected
     turnover from agents including 5% interest charge regarding the same issue.
     Inteltek management has replied this notification letter and rejected to
     pay the requested amount.

     On 9 November 2005, Spor Toto Teskilat Mudurlugu sent another notification
     letter to Inteltek that Inteltek is obliged to pay nominal amount of TRY
     3,292 (equivalent to $2,452 at 31 March 2006) due to the difference in the
     reconciliation methods. Spor Toto Teskilat Mudurlugu claims that the
     reconciliation periods should be six-month independent periods whereas
     Inteltek management believes that those periods should be cumulative as
     stated in the agreement. Inteltek did not pay the requested amount.

     Respective legal procedure is still pending. Based on its management and
     legal counsel's opinion Inteltek accrued nominal amount of TRY 3,292
     (equivalent to $2,452 at 31 March 2006) for this amount in the accompanying
     consolidated interim financial statements as at 31 March 2006 due to the
     probability of negative outcome of the declaratory action.

     Legal Proceedings (continued)

     Dispute on call termination fee

     Telsim has initiated a lawsuit claiming that, the Company has not applied
     the reference interconnection rates determined by the Telecommunications
     Authority, and has charged interconnection fees exceeding the ceiling rates
     approved by Telecommunications Authority and requested an injunction to be
     applicable starting from 1 August 2005, to cease this practice and
     requested a payment of its damages totalling to nominal amount of TRY
     26,108 (equivalent to $19,444 as at 31 March 2006) including principal,
     interest and penalty on late payment. On 6 April 2006, the case is
     rejected. The Company is still charging interconnection fees under the
     existing Interconnection Agreement with Telsim. As it is stated in the
     existing Interconnection Agreement with Telsim, Telsim referred the matter
     to the Telecommunications Authority. The resolution procedure has not been
     finalized yet. The management and legal counsel of the Company believe that
     it is premature to estimate the legal outcome at this point. Therefore, the
     Company has not recorded any accrual with respect to this matter in its
     consolidated interim financial statements as at 31 March 2006.

     Invalidity of the Board Resolution

     On 23 June 2005, the Board of Directors of the Company has decided to allow
     Alfa Group to conduct a due diligence in the Company and to entitle the
     management. On 1 July 2005, Sonera filed a suit with an injunction request
     against the Company for the purpose of determination of the invalidity of
     the resolution dated 23 June 2005. On 28 December 2005, the court rejected
     the injunction request of Sonera. Sonera has appealed this decision on 24
     February 2006.

     the GSM tender process, which was won by the Consortium. As a result, the
     Company has brought a claim in Iranian courts seeking to compel the
     Ministry to implement the laws and regulations passed by the Iranian
     Parliament in connection with the GSM tender process. The case is still
     pending.

     Dispute with the Telecommunications Authority with respect to temporary set
     call termination fees

     The interconnection agreement with Turk Telekom provided for a
     renegotiation of pricing terms on call termination fees after 31 December
     2004, and in the event that the parties could not agree on new terms by 28
     February 2005, for referral to the Telecommunications Authority for
     resolution. As the parties were unable to agree on new terms, Turk Telekom
     referred the matter to the Telecommunications Authority, which has set
     temporary call termination fees for calls terminating on each operator's
     network starting from 10 August 2005.

     Legal Proceedings (continued)

     Dispute with the Telecommunications Authority with respect to temporary set
     call termination fees (continued)

     On 7 October 2005, the Company filed a lawsuit against the
     Telecommunications Authority for the injunction and cancellation of this
     decision, which has set temporary call termination fees for calls
     terminating on each operator's network starting from 10 August 2005. The
     case is still pending. At this point in the litigation it is premature to
     estimate the legal outcome. As at 10 May 2006, the final termination fees
     have not been set yet.

     As mentioned above, Telecommunications Authority has set temporary call
     termination fees for calls terminating on each operator's network starting
     from 10 August 2005. However, Turk Telekom does not apply these termination
     fees for the international calls. Therefore, on 22 December 2005, the
     Company filed a lawsuit against Turk Telekom to cease this practice and
     requested collection of its damages totaling to nominal amount of TRY
     11,970 (equivalent to $8,915 at 31 March 2006) including principal,
     interest and penalty on late payment covering the period from August 2005
     until October 2005.

     These temporary prices are not as favorable to the Company as they have
     been previously, and the Telecommunications Authority may impose further
     reductions in call termination fees. At this point, the Company is unable
     to estimate the timing and impact of the possible changes to its fees,
     however, new pricing terms, could be lower and these could have an adverse
     affect on the Company's financial position, results of operations and cash
     flows.

     Dispute with Avea

     On 28 February 2006, Avea has initiated a lawsuit against the Company
     claiming that although there is an agreement between the Company and Avea
     stating that both parties would not charge any SMS interconnection
     termination fees, the Company has charged SMS interconnection fees for the
     messages terminating on its own network and also assumed liabilities for
     the messages terminating in Avea's network and made interconnection
     payments to Avea after deducting the net balance of those SMS charges and
     accruals. Avea requested provisions of Interconnection Agreement regarding
     SMS pricing to be applied and requested collection of its losses amounting
     to nominal amount of TRY 12,275 (equivalent to $9,142 at 31 March 2006) for
     the period between February 2005 and December 2005 with its accrued
     interest till payment. Based on its management and legal counsel's opinion,
     the Company has the right to charge SMS interconnection terminating fees
     with respect to SMS interconnection services provided to Avea. SMS
     interconnection fees charged to Avea, is the same with the SMS
     interconnection fees charged to other GSM operators in Turkey. The case is
     still pending. The management and legal counsel believe that the Company's
     claim on this issue has a fair basis. Accordingly, the Company charges SMS
     interconnection fees and has accrued with respect to its assumed
     liabilities as at and for the three months ended 31 March 2006.

24.  Contingencies (continued)

     Legal Proceedings (continued)

     Dispute on value added taxation with respect to roaming services

     On 6 April 2006, the Tax Office claimed that the Company should have paid
     VAT on the invoices issued by foreign GSM operators for the international
     calls originated by the Company's subscribers and terminating on those
     foreign GSM operators' networks during the year 2000. It has been notified
     that, based on the calculation made by the Tax Office, the Company should
     pay nominal amount of TRY 3,654 (equivalent to $2,721 at 31 March 2006) for
     VAT and also a penalty fee of nominal amount of TRY 16,137 (equivalent to
     $12,018 at 31 March 2006). Management decided not to pay such amounts and
     initiated a judicial process on 6 April 2006. Management and legal counsel
     believe that the Company will prevail in this matter. Accordingly, the
     Company has not provided any accruals with respect to this matter in its
     consolidated interim financial statements as at 31 March 2006.

     Dispute on ongoing license fee and universal service fund payment based on
     the amended license agreement

     Based on the enacted law on 3 July 2005 with respect to the regulation of
     privatization, gross revenue description based for the calculation of
     ongoing license fee and universal service fund has been changed. According
     to this new regulation, accrued interest charged for the late payments,
     taxes such as indirect taxes, and accrued revenues are excluded from the
     description of gross revenue. Calculation of gross revenue for ongoing
     license fee and universal service fund according the new regulation is
     valid after Danistay's approval on 10 March 2006. In the meanwhile, the
     Company realized the payments including above-mentioned items between 21
     July 2005 and 10 March 2006, when the amendment in license agreement was
     effective. On 21 April 2006, the Company initiated a lawsuit against
     Turkish Treasury for the difference between the payments that were realized
     started from 21 July 2005 until 10 March 2006 totalling TRY 111,316
     (equivalent to $82,905 at 31 March 2006) including interest of TRY 8,667
     (equivalent to $6,455 at 31 March 2006).

     The above-mentioned enacted law dated 3 July 2005 also assigned
     Telecommunications Authority for the revision of license agreement
     according to new regulation. However Telecommunication Authority suffered
     delay in the revision of license agreement. Therefore, on 5 May 2006, the
     Company has initiated a lawsuit against the Telecommunications Authority
     for the delay of the revision in license agreement preventing the new
     regulation to become effective until 10 March 2006. By this lawsuit, the
     Company has requested totalling TRY 112,317 (equivalent to $83,650 at 31
     March 2006) including interest of TRY 9,668 (equivalent to $7,200 at 31
     March 2006).

     Dispute on Telecommunication Authority fee payment based on the amended
     license agreement

     Based on the 9th article of the new license agreement dated 10 March 2006,
     the Company has been obliged to pay 0.35% of its yearly gross revenue once
     in a year as Telecommunication Authority Fee. However in the previous
     license agreement, the Company was obliged to pay 0.35% of its yearly gross
     revenue after deducting ongoing license fee, universal service fund and
     other indirect taxes from the calculation base whereas in the new
     agreement, these aforementioned payments are not deducted from the base of
     the calculation. Therefore, on 12 April 2006, the Company has initiated a
     lawsuit for the cancellation of the 9th article of the new license
     agreement.

     Substantially all of the significant due from related party balances are
     from Cukurova Group companies.

     Due from KVK Teknoloji, a company whose majority shares are owned by
     Cukurova Group, mainly resulted from simcard and prepaid card sales to this
     company.

     Due from A-Tel, a 50-50 joint venture of Yapi Kredi Bankasi AS ("Yapi
     Kredi") and Savings Deposit Insurance Fund ("SDIF"), mainly resulted from
     simcard and prepaid card sales to this company. On 28 September 2005,
     Cukurova Group transferred its Yapi Kredi shares to Koc Group following
     which A-Tel ceased to be considered a related party. In the Board of
     Directors meeting dated 22 March 2006, it is resolved to accept the
     proposal and to purchase 50% of A-Tel shares for a consideration of
     $150,000 based on the findings of the due diligence conducted at A-Tel.

     mainly resulted from balances paid in advance in order to benefit from the
     expertise and bargaining power of ADD with third parties in media
     purchasing.

     Due from Digital Platform, a company whose majority shares are owned by
     Cukurova Group, mainly resulted from receivables from call center revenues,
     financial support for borrowing repayments and advances given for current
     and planned sponsorships. On 23 December 2005, a "Restructuring Framework
     Agreement" was signed between Digital Platform and the Company. The
     agreement includes the restructuring of the Group's receivables from
     Digital Platform amounting to $82,993 as at 31 March 2006 in exchange for
     sponsorship and the advertisement services that the Company will receive on

     commits to pay amounts due to the Group through 15 July 2011 along with the
     interest in cash and advertisement services. $82,993 represents present
     value of future cash flows and services discounted using imputed interest
     rate. As at 31 March 2006, $75,749 of the balance is classified as long
     term due from related parties in accordance with the revised repayment
     schedule.

     KVK Teknoloji incorporated on 23 October 2002, one of the Company's
     principal SIM card distributors, is a Turkish company, which is affiliated
     with some of the Company's shareholders. In addition to sales of SIM cards
     and scratch cards, the Company has entered into several agreements with KVK
     Teknoloji, in the form of advertisement support protocols, each lasting for
     different periods pursuant to which KVK Teknoloji must place advertisements
     for the Company's services in newspapers. The objective of these agreements
     is to promote and increase handset sales with the Company's prepaid and
     postpaid brand SIM cards, thereby supporting the protection of the
     Company's market share in the prevailing market conditions. The prices of
     the contracts were determined according to the cost of advertising for KVK
     Teknoloji and the total advertisement benefit received, reflected in the
     Company's market share in new subscriber acquisitions. Distributors'
     campaign projects and market share also contributed to the budget
     allocation.

     Agreements with A-Tel:

     A-Tel is involved in the marketing, selling and distributing the Company's
     prepaid systems. A-Tel is a 50-50 joint venture of Yapi Kredi and SDIF.
     A-Tel acts as the only dealer of the Company for Muhabbet Kart (a prepaid
     card), and receives dealer activation fees and simcard subsidies for the

27.  Subsequent events

(a)  On 20 October 2005, Cukurova Group offered to sell the Company the A-Tel
     Option Contract, under which the holder has the right to purchase 50%
     shares of A-Tel for a consideration of $150,000. The Company conducted tax,
     legal and financial due diligence review at A-Tel. On 22 March 2006, the
     Board of Directors of the Company resolved to accept the proposal and the
     purchase 50% of A-Tel shares for a consideration of $150,000 based on the
     findings of the due diligence conducted at A-Tel. On 14 April 2006,
     Cukurova Holding declared Yapy Kredi that they use the right in question
     and in this respect, they also requested the sale of the above-mentioned
     shares at $150,000 to the Company.

(b)  On 22 March 2006, the Board of Directors of the Company decided to conduct
     the required studies for the pre-qualification stage and submit a
     prequalification application in accordance with the relevant provisions of
     the Request for Proposals dated 19 February 2006, for the tender of the
     third GSM license in Arab Republic of Egypt. In this respect, the Company
     signed a Memorandum of Understanding with Amwal El Khaleej and Banque Misr
     in order to form a consortium to apply for the pre-qualification of the
     third GSM license in Arab Republic of Egypt. The Company will have a 60%
     stake in the consortium where the remaining stake will be equally divided
     between other consortium members. On 2 May 2006, the Company obtained the
     letter of guarantee, in the name of the National Telecommunication
     Regulatory Authority, from Banque Misr. The Company is still evaluating the
     third GSM license in Arab Republic of Egypt. As at 4 May 2006, the Company
     submitted necessary pre-qualification documentation to the Authorities in
     Egypt.

(c)  Ordinary General Assembly of the Company, which was planned to convene on
     28 April 2006 postponed as the meeting quorum could not be reached. In
     order to discuss the same items as stated in the postponed meeting's
     agenda, Ordinary General Assembly meeting will be held on 22 May 2006.

(d)  In the Ordinary General Assembly Meeting, dated 3 April 2006, of DCC,
     merger of DCC with Astelit, another indirect subsidiary of the Company, was
     decided.

(e)  In the Shareholders Meeting of Kybris Telekom dated 27 April 2006, dividend
     distribution amounting to TRY 5,254 was decided.

(f)  The corporation tax rate is 30% for the three months ended 31 March 2006.
     However, the Prime Minister of Turkey has announced in December 2005 that
     the corporation tax rate will be reduced to 20% starting from 1 January
     2006. The issue is still being debated by the government as at 10 May 2006
     and as no change in tax rate has been enacted or substantially enacted by
     31 March 2006, the current tax rate of 30% has been consistently used.
     According to the Income Tax Law which has been published in Official
     Gazette on 8 April 2006, the investment allowance application has been
     abolished effective from 1 January 2006. However, the respective law allows
     the taxpayers to utilise their investment allowance rights obtained under
     the scope of the previous provisions only for their income generated in the
     years 2006, 2007, and 2008.

(g)  In the Ordinary General Assembly Meeting at 21 April 2006 of Aks TV, it was
     decided that share capital will be increased to TRY 50,000 of which TRY
     35,602 will be transferred from extraordinary reserves and TRY 14,298 will
     be in cash or through additional paid in capital. Iyi Eglenceler has to pay
     TRY 7,187, which is calculated according to the shareholder structure until
     31 May 2006.

(h)  Turktell Uluslararasy applied to the Turkish Treasury on 28 April 2006 for
     the permission of capital transfer to abroad in order to participate in the
     capital increase of Euroasia amounting to $22,020 million which is
     calculated according to its shareholding rate at Euroasia.

28.  Accounting estimates and judgements

     Management discussed with the Audit Committee the development, selection
     and disclosure of the Company's critical accounting policies and estimates
     and the application of these policies and estimates. In note 2, detailed
     analysis is given with respect to accounting estimates and judgements of
     bad debts, useful life or expected pattern of consumption of the future
     economic benefits embodied in, depreciable assets and deferred tax assets.

     Key sources of estimation uncertainty

     In note 21, detailed analysis is given of the foreign exchange exposure of
     the Company and risks in relation to foreign exchange movements.

     Critical accounting judgements in applying the Company's accounting
     policies

     Certain critical accounting judgements in applying the Company's accounting
     policies are described below.

     Trade and other receivables

     The impairment losses in trade and other receivables are based on
     management's evaluation of the volume of the receivables outstanding, past
     experience and general economic conditions.

     Useful life of assets

     The useful economic lives of the Group's assets are determined by
     management at the time the asset is acquired and regularly reviewed for
     appropriateness. The Group defines useful life of its assets in terms of
     the assets' expected utility to the Group. This judgement is based on the
     experience of the Group with similar assets. In determining the useful life
     of an asset, the Group also follows technical and/or commercial
     obsolescence arising on changes or improvements from a change in the
     market. Life of the License is based on duration of license agreement.

29.  Explanation of transition to IFRSs

     As stated in note 1, these are the Company's first consolidated interim
     financial statements for part of the period covered by the first IFRS
     annual consolidated interim financial statements prepared in accordance
     with IFRSs.

     The accounting policies set out in note 1 have been applied in preparing
     the consolidated interim financial statements for the three months ended 31
     March 2006, the comparative information for the three months ended 31 March
     2005, the consolidated financial statements for the year ended 31 December
     2005 and the preparation of an opening IFRS balance sheet at 1 January 2005
     (the Group's date of transition).

     In preparing its opening IFRS balance sheet, comparative information for
     the three months ended 31 March 2005 and financial statements for the year
     ended 31 December 2005, the Group has adjusted amounts reported previously
     in its consolidated financial statements prepared in accordance with
     previous GAAP (US GAAP). An explanation of how the transition from US GAAP
     to IFRSs has affected the Group's financial position, financial performance
     and cash flows is set out in the following tables and the notes that
     accompany the tables.

     a) Revenues:

     Under US GAAP, revenues, gross profit, and selling and marketing expenses
     were reduced due to the standards issued by the Emerging Issues Task Force
     (EITF) within the Financial Accounting Standards Board (FASB) that
     addressed the extent to which different types of payments or benefits to
     retailers or customers shall be reported as reductions either in revenue or
     incurred as expenses. With the transition to IFRS, EITF rules are no longer
     applied.

As at and for the three months ended 31 March 2006
(Amounts expressed in thousands of US dollars unless otherwise indicated except
share amounts)
--------------------------------------------------------------------------------


29.  Explanation of transition to IFRSs (continued)


     b) Financial Instruments:

     IAS 32 "Financial Instruments: Disclosure and Presentation" and IAS 39
     "Financial Instruments: Recognition and Measurement" address the accounting
     for, and reporting of, financial instruments. IAS 39 sets out detailed
     accounting requirements in relation to financial assets and liabilities.
     Financial assets and liabilities are stated at present value using
     effective interest method with charges flowing through the income
     statement. Under US GAAP there is no requirement for discounting in certain
     specified circumstances including trade receivables and payables maturing
     in less than one year and for borrowings.

     c) Restatement of Non Monetary Items:

     Under US GAAP, revenues, costs, capital and non-monetary assets and
     liabilities are translated at historical exchange rates while monetary
     assets and liabilities are translated at exchange rates prevailing at
     balance sheet dates. All foreign exchange adjustments resulting from
     translation of financial statements into US dollars are included in
     determination of net income whereas under IFRS, when the functional
     currency is the currency of a hyperinflationary economy, the reported
     revenues, costs, capital and non monetary assets and liabilities are
     recognized based on IAS 29 principles in terms of the measuring unit
     current at the balance sheet date. Depreciation and amortization, monetary
     gain/(loss) accounts are also affected by these accounting differences.

     As hyperinflationary conditions in Turkey no longer existed starting from 1
     January 2006, TRY has been treated as a more stable currency since that
     time and the financial statements of the Company and those of the
     subsidiaries located in Turkey and Turkish Republic of Northern Cyprus
     prepared in accordance with IFRS are not required to be adjusted for
     hyperinflationary accounting.

     d) Deferred Tax:

     Distinctions arise in deferred tax calculation due to the accounting
     methodology differences between US GAAP and IFRS standards.

     e) Share of earnings in associates and minority interest:

     The Group's share of net income of its associate is determined using the
     equity method and is based on financial statements of the investee's
     prepared in accordance with IFRS. The reconciliation item reflects
     adjustments for the difference between IFRS and US GAAP relating to the
     separate financial statements of subsidiaries and the associate.

     f) Change in presentation:

     Amounts within the reconciliations for the year ended 31 March 2006 and 31
     December 2005 and shareholder's equity as at 31 March 2005, 31 December
     2005 and 31 December 2004 have been reclassified to provide comparability.
     The reclassification does not have an effect on net income under IFRS.
