         TURKCELL ILETISIM HIZMETLERI A.S. REPORTS 2004 YEAR END RESULTS


     Impressive growth and strong results on the back of favorable operating
                                   environment


Istanbul, Turkey, April 6, 2004 - Turkcell (NYSE:TKC, ISE:TCELL),
(www.turkcell.com.tr), the leading provider of mobile communications services in
Turkey, today announced results for the year ended December 31, 2004. All
financial results in this press release are unaudited and reported in accordance
with accounting principles generally accepted in the United States (US GAAP) and
are expressed in US$.

Figures in brackets following the operational and financial results for the year
2004 refer to the same item in the year 2003 and figures in brackets following
the operational and financial results for the fourth quarter of 2004 refer to
the same item in the third quarter of 2004.

In 2004, the Turkish Parliament approved a law requiring the removal of six
zeros from the Turkish Lira and the creation of a new currency, the New Turkish
Lira ("TRY"). One US$ equaled TRY 1.3421 at December 31, 2004. Therefore,
effective January 1, 2005 one million Turkish Lira will be equal to one New
Turkish Lira. Turkish Lira will remain in circulation along with the New Turkish
Lira until the end of 2005, at which time only the New Turkish Lira will remain
in circulation.

Comments from the CEO, Muzaffer Akpinar
--------------------------------------------------------------------------------

The year ended December 31, 2004 was a year of growth in a favorable operating
environment. We achieved strong operational results while maintaining our
leading position in the market with a market share of 67% according to the
figures prepared by the Telecommunications Authority. We recorded 23% growth in
our subscriber base as well as 11% growth in usage. We generated strong
financial results and maintained our focus on cost efficiency.

During 2004, we settled our legal disputes with Turk Telekom and with the
Turkish Treasury, and we believe that the settlements are satisfactory for
Turkcell and our shareholders.

                                                                               2



The Turkish telecommunications market underwent considerable changes during the
year. One GSM operator was seized by the government, while the other two GSM
operators completed a merger with one another. As a result, we now operate in a
three operator environment. The Turkish government commenced the privatization
process for Turk Telekom and announced May 2005 as the deadline for the bidders
to enter the process. In addition to the foregoing, the Telecommunications
Authority issued Long Distance Traffic Carriers licenses and some of the
licensees have already commenced operations.

We believe that the foregoing changes in the market will have an impact in our
operational environment, in particular with regard to increasing the level of
competition. As a result, the intense competition and pricing pressures we have
seen throughout the year may continue. However, we would like to remain
optimistic that the liberalization efforts leading to the privatization of Turk
Telekom and the sale of one of the GSM operators could provide a more
commercially-oriented competitive environment in the future.

During 2004, we have seen introduction of price discounts by our competitors in
the market. This price competition continued during the first quarter of 2005.
Discounts generally evolved from being mainly on-net community discounts to
include off-net discounts to GSM and to fixed line callings and flat rate tariff
plans for all directions in 2005. Our intention is to continue to keep our focus
on a `Better Value for Money' approach as we are developing offers to further
suit the needs and expectations of our customers. In 2004, we proactively
managed our position in the market by monitoring these developments and taking
necessary actions to improve customer satisfaction with service and product
offerings. As a result, we achieved lower churn rates during 2004 in comparison
to the previous year.

We have also kept building on our technological leadership through our
commitment to advanced technologies such as EDGE (Enhanced Data rate for GSM
Evolution), which provides higher access speeds, and the continued roll-out of
our nationwide 2.5G network. We believe our planned network investments of
US$500 million in 2005 should allow us to retain our leadership position, in
terms of service quality and coverage.

On the international front, Eurasia, our effectively 51% owned subsidiary
through its subsidiary Astelit introduced its new brand "life :)" on February 1,
2005 in the Ukrainian GSM market, using GSM 1800 technology. We will continue
rolling out services in Ukraine with the aim of improving our position in the
market.

We have had set backs in Iran after the Parliament of Iran amended the
previously-agreed license agreement between Irancell and the government. We
understand that after the Guardian Counsel of Iran has rejected these amendments
of the Parliament, Parliament of Iran sent amendments back to Guardian Counsel
with limited changes. As the existing amendments create restrictions on
management and control rights as well as our ability to consolidate Irancell's
financial results into our financials statements, they significantly differ from
the original license terms and jeopardize our ability to go forward with the
project. Nevertheless, our interest regarding Iranian market continues and we
expect that our involvement should resume through monitoring the on-going
process or any new future direction.

During 2004, we were honored to have been re-elected to the Board of the GSM
Association, which represents more than 670 second and third generation mobile
operators with over 1.2 billion subscribers and handset manufacturers around the
world. Our election to this post is an indication of our continuing success, and
we believe we will continue to contribute through this platform to both global
and local development of the GSM standards.

We believe the outlook for 2005 is positive given the overall strength of the
Turkish economy, in which we expect single digit inflation and improved consumer
sentiment. Similarly, a positive resolution with the IMF regarding a new standby
agreement and the start of the EU accession talks

                                                                               3



in October 2005 should provide an additional boost to the economic and business
environment in Turkey. However, we are mindful that political and regional
tensions have in the past had an impact on the economic performance of the
Turkish economy and our operating environment and may continue to do so in the
future. Therefore, while we remain optimistic for the year ahead, we will
continue to monitor these external developments that may have an impact on our
business environment.

In 2005, we aim to maintain our leading position in our local market by
continuing to capitalize on our well-established brand name, customer focused
approach, nationwide quality network coverage, and extensive distribution
channels. We believe our strong market position and financial strength will
continue to provide a solid base for meeting the challenges of our changing
operating environment.

We intend to continue moving ahead with our international operations in 2005.
Our intention is to build a fundamentally sound business in Ukraine while
following up on issues regarding our investment in Iran. Given the delays we
have faced in Iran, we may also selectively evaluate other international
opportunities in the region as they may arise in the future.

On March 25, 2005 TeliaSonera announced that it had reached an agreement with
the Cukurova Group to acquire an additional effective 27% of the shares in
Turkcell for a cash consideration of US$3.1 billion. This transaction would
increase TeliaSonera's effective ownership stake to 64.3% from 37.09%. As
announced, the transaction is expected to be completed in the second quarter of
2005 and is subject to agreement on completion of documentation and receipt of
regulatory approvals.


Overview
--------

Improved consumer sentiment and a favorable macroeconomic environment helped us
produce strong operational and financial results. Revenues increased 44% to
US$3.2 billion (US$2.2 billion) mainly as a result of the growth in the
subscriber base and increase in usage. We recorded 23% growth in our subscriber
base and reached 23.4 million (19.0 million) at December 31, 2004 as a result of
the 4.4 million net new subscriber additions. At the same time, our annual churn
rate decreased to 9.1% (14.5%) for 2004. The annual average minutes of usage per
subscriber increased by 11% in 2004 and reached 64.9 minutes.

The mobile line penetration rate in Turkey reached approximately 50%, which is
low relative to mobile penetration rates elsewhere in Europe. Given the
demographics of the Turkish population and market dynamics, we expect the
Turkish market to continue to grow, although at a slower rate than the past few
years. We also expect the growth in the market to come predominantly from
prepaid subscribers.

The evolution of the Turkish telecom sector is continuing. The tender process
for Turk Telekom's privatization commenced in November 2004 and will continue in
2005. As we announced in January 2005, we submitted an application through one
of our subsidiaries, Turktell Bilisim Servisleri A.S. ("Turktell"), as part of a
large consortium, which was pre-qualified and accepted for participation in the
tender. In addition, the sale of Telsim is still on the agenda of the SDIF
(Savings Deposit Insurance Fund), which is currently managing Telsim. Currently,
there is no announced date for the sale of Telsim. As these changes and their
timing will affect our operational environment, we will monitor these and
related developments closely.

On the GSM front, aggressive price competition dominated the year. Our ambition
remains to enhance the customer satisfaction through our segmented approach in
service, product and tariff offerings while sustaining a balance with our
revenue goals. One of the most significant offers we

                                                                               4



have introduced in 2004 was the introduction of "PSTN=ON-NET", which was
actually a continuation of our "GSM to PSTN" discount campaign, initiated on
March 2004, and the "three number calling option at half price" campaign where
one number could be a PSTN number introduced in July 2004. We believe our offer
has been effective in improving usage levels and the results are in line with
our expectations.

We believe lower termination rates in the wholesale side have been another
factor in our market since September 2003, which have led to further pricing
pressures. Along with the already lower rates, the reference tariff structure
introduced by the Telecommunications Authority during the year may impose
further reduction in rates which may come into effect if the current discussions
between operators to renew existing pricing terms of the interconnection
agreements do not result in an agreement. Currently, an escalation has been made
by Telsim and it is likely that Turk Telekom may escalate this issue to the
Telecommunication Authority for its intervention.

We continued to build on technological leadership in the market throughout the
year and in 2005 through the introduction of new services and products to enrich
our offerings. We continued to invest in infrastructure enabling services such
as, Push-to-Talk, Ringback tone and Active Camel. We also enlarged our product
portfolio with new value added services such as Instant Messaging Service, and
M-Ticketing. Our service offerings will continue throughout 2005 with our
objective to enrich lives of our subscribers with advanced, yet suitable,
offerings and underlying advanced technology. Our recent introduction of EDGE
(Enhanced Data rate for GSM Evolution) technology provides our subscribers with
faster Internet access through their GSM handsets as well as laptops.
Furthermore, we have already set up a third generation ("3G") trial system and
begun discussing details of the 3G trial system internally. The licensing
process and, in particular the distribution of 3G licenses in Turkey, is
currently not clear yet, but we intend to play a leading role in this area once
it is underway.


Settlement Agreements
--------------------------------------------------------------------------------

As announced in December 2004, we have settled the dispute regarding the call
termination pricing for the period between April 1998 and September 2003 with
Turk Telekom, and the dispute on the calculation and payment of Turkcell's
ongoing 15% license fee to the Turkish Treasury for the period April 1998
through May 2004. The agreements became effective as of December 24, 2004.

Settlement Agreement regarding Turk Telekom Dispute

Turkcell and Turk Telekom calculated Turk Telekom's receivables as TRY1,808
million (US$1,347 million as of December 31, 2004), including principal,
interest, Value Added Tax ("VAT") and Special Communications Tax ("SCT") and
Turkcell's receivable as TRY 278 million (US$207 million as of December 31,
2004), including principal, interest, VAT and SCT. After netting the
receivables, Turkcell and Turk Telekom agreed that Turkcell owed Turk Telekom a
total of TRY1,531 million (US$1,141 million as of December 31, 2004), including
principal, interest, VAT and SCT. Turkcell accepted this agreement and committed
to pay TRY998 million (US$744 million as of December 31, 2004) after the
deduction of Turk Telekom's collections through November 30, 2004, amounting to
TRY533 million (US$397 million as of December 31, 2004), including principal,
interest, VAT and SCT.

The amounts of the settlement are in line with the provisions we have provided
as of the quarter ended September 30, 2004. However, since the settled amounts
are denominated in TRY and include taxes, there has been a change in US$ amounts
due to appreciation of TRY against US$. In accordance with the agreement, the
amount paid in the fourth quarter of 2004 amounts to TRY32 million (US$24
million as of December 31, 2004) excluding taxes. The remaining principle
balance of TRY766 million excluding taxes (US$571 million as of December 31,
2004) as of

                                                                               5



December 31, 2004, will be paid in 17 equal monthly installments starting on
January 1, 2005. Monthly payments for January, February and March 2005 have been
made. Interest will be paid on the installment amounts, according to the payment
plan. The monthly interest rate will be calculated from the annual simple
interest rate of the most recent date to 15th of the payment month, TRY
denominated discount bond issued by the Turkish Treasury. The interest payment
for each installment will be calculated on the outstanding balance after the
last payment.

Settlement Agreement regarding the Turkish Treasury Dispute

According to the agreement, Turkcell agreed to pay TRY867 million (US$646
million as of December 31, 2004) to the Treasury, which comprised of TRY597
million (US$445 million as of December 31, 2004) in principal, and TRY270
million (US$201 million as of December 31, 2004) in interest. These settled
amounts are in line with the provisions we have provided as of the quarter ended
September 30, 2004.

Turkcell paid TRY600 million (US$447 million as of December 31, 2004) principal
and an additional interest of TRY6 million (US$5 million) on outstanding
balances in the fourth quarter of 2004 with the remaining balance of TRY267
million (US$199 million as of December 31, 2004) due in three equal payments in
January, February, and March of 2005. Interest is added to each payment,
calculated from the previous months average annual simple interest rate of the
TRY denominated discounted bonds issued by the Turkish Treasury. As of the date
of this announcement the payments have been completed and the total TRY882
million (US$657 million) including principal and interest has been paid.

With regards to the settlement agreement with the Treasury, the resolution
covers the disputed period starting from April 1998 through to the date on which
the agreement was finalized, which was May 31 2004. The parties agreed to
exclude the education fund and frequency usage and transmission fee from the
calculation of gross revenue on which the 15% Treasury fee is calculated and to
include other disputed items in the calculation for the subject period. As
practice, Turkcell has paid 15% Treasury Share on all gross revenue items
excluding education fund and frequency usage and transmission fee including 18%
VAT throughout 2004 as per the settlement agreement. Turkcell also continued the
same practice for the applicable period in 2005 with a reservation while the
discussions with between the parties to exclude indirect taxes such as 18% VAT
and interest charges for late collection from subscribers from gross revenue are
still continuing.

The repayment schedule for the remaining principle balances, excluding taxes, as
of January 1, 2005 is as follows:

                                                                               6



Dividend Distribution
--------------------------------------------------------------------------------

In accordance with the dividend policy that we have adopted, which is set out in
our Corporate Governance Guidelines, the Board of Directors intends to
distribute cash dividends in an amount of not less than 50% of our distributable
profits, for each fiscal year, starting with profits for fiscal 2004. However,
the payment of dividends will still be subject to our cash flow requirements,
compliance with Turkish laws and regulations and the approval of, or amendment
by, the Board of Directors and the General Assembly of Shareholders to be held
on April 29, 2005.


International Investments

Fintur International continued its strong growth in the fourth quarter of 2004.
The GSM businesses in Azerbaijan, Kazakhstan, Georgia and Moldova added
approximately 407,000 net new subscribers, raising the total number of
subscribers to approximately 3.9 million (3.5 million) as of December 31, 2004.
Furthermore, in the fourth quarter of 2004 revenues were US$164 million (US$155
million), leading to a 6% increase compared to the third quarter of 2004. The
combined revenue of Fintur reached US$ 557 million and the EBITDA of each
business was positive in 2004. We own 41.45% of Fintur and account for this
investment using the equity method, which totaled US$44 million income in 2004.

Ukraine
-------

Our 51% owned subsidiary Astelit, introduced its new brand "life :)" on February
1, 2005 in the Ukrainian GSM market. Having targeted capital expenditures of
around US$250 - 300 million in the first two years of operations, Astelit signed
three vendor financing agreements with Nokia ((euro)125 million), Ericsson
(US$89 million) and Sysdate (US$13 million). Turkcell guaranteed Astelit's
obligations in proportion to its investment and Astelit aims to continue its
investments in the following years to come and we may provide guarantees for the
future financing arrangements.

Currently, life :) is operating in 21 major cities and planning to increase its
coverage to 91 cities and the majority of the country's tourist areas and
principal intercity highways. By the end 2005, life :) is planning to cover
approximately 70% of the population living in cities with more than 5,000 or
more inhabitants.

Since the acquisition of Astelit in the second quarter of 2004, operations in
Ukraine have been consolidated in Turkcell's financial statements.

As per the working capital requirements of Astelit, we expect that there will be
an increase in the paid in capital by US$50 million and we intend to participate
to the capital increase of the company.

Iran
----

We have had set backs in Iran after the Parliament of Iran amended the
previously-agreed license agreement between Irancell and the government. We
understand that after the Guardian Counsel of Iran has rejected these amendments
of the Parliament, Parliament of Iran sent amendments back to Guardian Counsel
with limited changes. As the existing amendments create restrictions on

                                                                               7



management and control rights as well as our ability to consolidate Irancell's
financial results into our financials, they significantly differ from the
original license terms and jeopardize our ability to go forward with the
project.

Turkcell had fulfilled the tender requirements of the government and signed a
license agreement prior to suggested changes by the Parliament. At this point,
Turkcell has incurred insignificant amount of operational expenses and no
investments have been made in Iran.

Nevertheless, our interest regarding Iranian market continues and we expect that
our involvement should resume through monitoring the on-going process or any new
future direction.

Exchange Rate Information
--------------------------------------------------------------------------------

One US$ equaled TRY 1.3421 (equaled to TL 1,342,100) as of December 31, 2004,
which implies a quarterly 10% appreciation of TRY against US$ in the fourth
quarter of 2004, and a yearly 4% appreciation of TRY against US$ in 2004. The
wholesale price index and consumer price index increased by 13.8% and 9.3%,
respectively in 2004. In 2003, there was a 15% appreciation of TRY against US$.


Financial and Operational Review
--------------------------------------------------------------------------------

The following discussion focuses principally on the developments and trends in
our business in the fourth quarter of 2004. We believe that a year on year
comparison both on a quarterly or an annual basis is not practical due to the
additional provisions recorded in 2003 and 2004. Nevertheless, selected
financial information for the fourth quarter of 2003 is included at the end of
this press release.

Subscribers

We added approximately 1.1 million net new subscribers in the last quarter of
2004, raising our total number of mobile subscribers to 23.4 million as of
December 31, 2004, up from 22.3 million subscribers at September 30, 2004.
Accordingly, the quarterly growth in our subscriber base was 4.8% while annual
growth was approximately 23% during 2004, up from 19.0 million subscribers at
December 31, 2003. The overall subscriber base consisted of 5.1 million postpaid
and 18.3 million prepaid subscribers as of year-end 2004. New gross subscribers
acquired in 2004 consisted of 89% prepaid and 11% postpaid subscribers. The 23%
increase in our overall subscriber base was supported by the favorable economic
environment and low subscriber churn rate, which is driven by our segmented
churn prevention activities and mass loyalty programs.

Revenues

We recorded US$879.5 million (US$969.3 million) in revenues in the fourth
quarter of 2004, which implies a 9% decline compared to the third quarter of
2004 mainly due to seasonality and negative effect of Ramadan in usage (13%), in
spite of the 10% appreciation of TRY during the quarter. After stripping out the
adverse effect of additional provisions on revenues last year, we can conclude
that, the decrease in revenues in the fourth quarter of 2004 compared to the
third quarter of 2004 was lower than the same periods in 2003, mainly because of
the growth in our subscriber base and the increase in usage, as well as
appreciation of TRY against US$.


On an annual basis, revenues increased 44% to US$3,200.8 million (US$2,219.2
million) as a result of the growth of the subscriber base, increase in usage,
4.95% increase in tariffs, and 4% appreciation of TRY.


In 2005, we expect our revenues to increase at a slower pace compared to 2004,
mainly derived from increase in subscriber base and appreciation of TRY against
US$, together with the improvement in the macroeconomic indicators and improving
usage.


MoU

                                                                               9



Usage in the last quarter of the year has historically been lower than in the
third quarter as people become less mobile due to winter and the Ramadan. On the
back of this trend, our blended MoU decreased by 13% to 63.8 minutes (73.6
minutes) in the fourth quarter of 2004.

However, the improvement in the macroeconomic environment, which induced
spending as well as our volume and segment-based campaigns led to increase in
usage levels throughout 2004, and the average MoU increased by 11% to 64.9
minutes (58.5 minutes) in 2004.


Despite the fact that we believe the aggressive price competition will continue
in 2005 we expect that the blended MOU will improve slightly in 2005 compared to
2004 due to the improvement in the macroeconomic indicators and consumer
sentiment, our strong CRM activities, and the continuing impact of volume based
campaigns.

ARPU

Our blended average revenue per user ("ARPU") decreased to US$12.4 (US$14.7) in
the fourth quarter of 2004 as a consequence of seasonally lower usage. ARPU for
prepaid and postpaid subscribers was US$7.6 (US$8.9) and US$29.0 (US$33.8),
respectively during the same quarter. For the sake of comparison, after
elimination of the effect of the provisional adjustments made in the fourth
quarter of 2003, we can conclude that the drop in both postpaid and prepaid ARPU
in the fourth quarter of 2004 compared to the third quarter was more moderate
compared to that in the same period in 2003.

As for 2004, blended ARPU was US$12.3 (US$10.6) and postpaid and prepaid ARPU
was US$29.2 (US$24.4) and US$7.2 (US$5.4), respectively. However, the dilutive
impact of growing prepaid subscriber base limited the growth in ARPU in 2004.


Despite the fact that we expect the blended MOU to improve slightly in 2005, we
expect blended ARPU to stay at similar levels as 2004 mainly due to decrease in
incoming revenue, the dilutive impact of increasing prepaid subscribers and
continued "better value for money" initiatives started in 2004.

EBITDA

EBITDA in the fourth quarter of 2004 deteriorated by 20% to US$384.1 million
(US$481.1 million) mainly due to the 9% decline in revenues. EBITDA margin
decreased to 44% (50%) in line with the increase in selling and marketing
expenses, as well as general administrative expenses as a percentage of total
revenues.

EBITDA in 2004 was US$1,338.8 million (US$642.9 million) while EBITDA margin
climbed to 42% up from 29% in 2003. Despite the difficulty of making a year on
year comparison due to the distortions of provisions recorded in both 2003 and
2004, we can conclude that the operational success in 2004 resulted in increased
EBITDA levels compared to that in 2003.

In 2005, we believe 40% historical EBITDA margin is sustainable. However, based
on strong TRY and further improvements of macro economic conditions may result
in better EBITDA margin.

                                                                              10



Translation gain

The appreciation of TL by 10% in the fourth quarter of 2004 led to a translation
loss of US$32.7 million (US$12.7 million gain) mainly due to TL based provisions
or liabilities in our Balance Sheet.

We recorded US$11.2 million translation loss in 2004 as opposed to US$102.4
million in 2003. The main reason underlying this improvement was the
appreciation of TRY, which stood at lower levels of 4% in 2004 vs. appreciation
of 15% in 2003, accompanied by a decrease in TRY based provisions due to the
settlements and related payments.

Churn rate

Churn refers to disconnected subscribers, whether disconnected voluntarily or
involuntarily. Turkcell's churn rate remained stable at 2% (2%) in the fourth
quarter of 2004.

Annual churn rate in 2004 declined to 9.1% from 14.5% in 2003. Churn prevention
efforts contributed to the improvement in the churn rate backed by positive
market conditions and strong CRM capabilities.

We expect that churn rates will increase as a result of the increase in
competition in the market in 2005, but we expect that it will remain below 2003
levels.


Profit & Loss and Balance Sheet Statements
--------------------------------------------------------------------------------

Net income

We recorded US$138.6 million (US$150.6 million) net income in the fourth quarter
of 2004. The 8% decrease in net income is due to mainly the decrease in
revenues, and the increase in interest expense.

We posted net income of US$511.8 million (US$215.2 million) in 2004, a 138%
increase. The main reason for the significant improvement in 2004 was the
distorting effect of additional legal provisions booked in the fourth quarter of
2003.

Direct cost of revenues

The direct cost of revenues, including depreciation and amortization was
US$477.6 million (US$549.3 million), which represents a 13% quarter on quarter
decline in nominal terms. The proportion of direct cost of revenues in total
revenue improved to 54% (57%) mainly due to decrease in revenue related costs
and the impact of expenses recorded regarding Turk Telekom infrastructure
dispute and roaming dispute in the third quarter of 2004 not included in the
fourth quarter of 2004.

In 2004, direct cost of revenues including depreciation and amortization was
US$2,001.2 million (US$1,613.2 million). The effect of additional legal
provisions in the last quarter of 2003 and 2004 related to various disputes had
distortions on direct cost of revenues and their percentages in total revenues
throughout.

Depreciation and amortization

                                                                              11



Depreciation and amortization remained broadly stable at US$107.2 million
(US$105.4 million) in the fourth quarter of 2004 as well as for the year 2004 at
US$424.2 million (US$421.5 million).

Selling and marketing expenses

Our selling and marketing expenses increased by 20% to US$107.2 million (US$89.0
million) in the fourth quarter of 2004 on the back of increasing advertising
expenses. This was mainly due to some New Year campaigns and roaming related
advertisements during the holiday season. Parallel to this, the proportion of
selling and marketing expenses in revenues increased to 12% (9%).

Selling and marketing expenses in 2004 were US$349.3 million (US$294.6 million),
which constituted a 19% year on year rise. However, the share of selling and
marketing expenses in revenues declined to 11% from 13% mainly due to the 44%
increase in revenues in 2004 and the impact of legal provisions in 2003 related
to Telecommunications Authority investigation related to and frequency usage fee
expenses.


General and administrative expenses

We recorded US$43.3 million (US$26.5 million) general and administrative
expenses in the fourth quarter of 2004. Accordingly, the proportion of general
and administrative expenses in revenues increased to 5% (3%) due to payments
made related to the dispute on deposits with a Turkish Bank, one time expenses
related to Iran project and related consultancy fees.

During 2004 we recorded US$137.3 million (US$137.2 million) general and
administrative expenses which remained almost stable and consequently a decrease
in share of revenues to 4% (6%) was recorded.


Equity in net income of unconsolidated investees

Fintur continued its strong performance throughout the fourth quarter of 2004,
and we recorded US$11.8 million (US$15.4 million) equity in net income of
unconsolidated investees.

Due to the same reason, the equity in net income of unconsolidated investees
more than doubled to US$43.6 million (US$18.9 million) in 2004.


Net interest income/(expense)

Net interest expense increased in the fourth quarter of 2004 to US$45.2 million
(income of US$78.0 million) mainly due to interest expenses on outstanding
balances related to settlement payments and income effect of additional legal
provisions related to the Treasury Share dispute settlement provided in the
third quarter of 2004, not included in the fourth quarter of 2004. We recorded a
net interest income of US$31.3 million in 2004 compared to the net interest
expense of US$366.3 million in 2003, mainly due to the distorting effect of
additional legal provisions.

                                                                              12



Income tax benefit (expense)

Turkcell recorded US$54.8 million of income tax expense (of which US$45.3
million and US$9.5 million were related to current tax charge and deferred tax
charge, respectively) in the fourth quarter of 2004 compared to US$264.0 million
income tax expense in the previous quarter.

Total tax expense recorded in 2004 was US$281.4 million, and US$477.3 million
income in 2003.

In 2004, tax expenses were mainly due to the deferred tax effect of the payments
related to legal disputes in 2004, which is tax deductible from the corporate
tax basis as of 2004 year end and additional provision for withholding tax to be
paid on taxable income of 2004.

The Ministry of Finance confirmed that Turkcell's payments made to Turk Telekom
and the Treasury, based on settlement agreements, is tax deductable from our tax
base whenever they are paid. Therefore, we reversed a portion of our deferred
tax assets based on the payments made in connection with the settlements and
deducted from our corporate tax base in 2004.

Additionaly, we recorded income tax expense (at the rate of 19.8%) of US$45.3
million (US$49.0 million) as of fourth quarter 2004 and US$94.3 million (US$
65.9 million) for the year 2004. The amount will be paid in TRY in May 2005.
Since our investment incentive certificates provide tax benefit in the form of
deductions for corporate tax purposes, we are exempt from 33% corporate tax
(applicable in 2004); instead such deductions are subject to withholding tax at
the rate of 19.8%.


Total assets

In the fourth quarter of 2004, our total assets decreased slightly to US$4,361.5
million (US$4,434.7 million).


Capital Expenditures

In the fourth quarter of 2004, we recorded US$134.6 million (US$153.5 million)
capital expenditures, US$47 million (US$47 million) of which was related to the
Ukrainian operations.

Total capital expenditures in 2004 amounted to US$486.7 million (US$172.9
million). The year on year increase mainly stemmed from US$176 million capital
expenditures related to Ukraine operation, which started to be consolidated in
the second quarter of 2004, as well as the capacity expenditure related to
capacity increase in the local operations due to the growth in our subscriber
base and increase in usage levels.


Debt

Turkcell's consolidated indebtedness including indebtedness from the Ukraine
operation amounted to US$832.6 million (US$790.9 million) in the fourth quarter
of 2004. Of the total amount, US$67 million (US$26 million) was related to
Ukraine operations.


Reconciliation of Non-GAAP Financial Measures

                                                                              13



The Company complies with the SEC's guidance regarding the use of non-GAAP
financial measures. We believe that EBITDA is a measure commonly used by
companies, analysts and investors in the telecommunications industry that
enhance the understanding of our operating results and assist in the evaluation
of our capacity to meet our financial obligations. We also use EBITDA as an
internal measurement tool and accordingly, we believe that the presentation of
EBITDA provides useful and relevant information to analysts and investors. We
are continuing to monitor developments in the interpretation of these new rules
and will make adjustments to the use of non-GAAP measures as may be required.

EBITDA equals net income (loss) before depreciation and amortization, interest
expense and income tax benefit (expense). EBITDA is not a measurement of
financial performance under US GAAP and should not be construed as a substitute
for net earnings (loss) as a measure of performance or cash flow from operations
as a measure of liquidity.

The following table provides a reconciliation of EBITDA, which is a non-GAAP
financial measure, to net cash provided by operating activities, which we
believe is the most directly comparable financial measure calculated and
presented in accordance with US GAAP.

representing 25.785829% stock dividend per share. Turkcell shareholders will not
be subject to a withholding tax deduction from the gross dividend according to
the current tax regulations.

The dividend must be approved by Turkcell's shareholders at its Annual General
Meeting to be held on April 29, 2005. If the dividend is approved by Turkcell's
shareholders, it will commence payment of the cash dividend on May 17, 2005 and
it will commence payment of the share dividend on May 31, 2005.

You should note that the cash dividends and stock dividends described above are
based on the existing ordinary shares with nominal value TL1,000 (YTL 0.001) and
the current ADR ratio of 2,500 existing ordinary shares to one ADR. However,
Turkcell is currently in the process of seeking approval from its shareholders
to merge 1,000 existing ordinary shares, each having a nominal value of TL1,000
(YTL 0.001), to 1 ordinary share having a nominal value of TRY1. As a
consequence, Turkcell will also change its ADR ratio to reflect the reduction in
the number of its ordinary shares. Since the foregoing process is subject to the
Capital Markets Board's announcement of the procedures for share merger and
dematerialization, and as we do not know when such announcement will be made, we
can not predict when the foregoing changes will be made. However, to the extent
that the changes occur prior to the dividend payment dates, we will make the
dividend payments on the basis of the new ordinary shares and the new ADR ratio.
In such case, a cash dividend of TRY 0.169619 (US$0.1261*) per ordinary share
and approximately TRY 0.424 (US$0.315*) per ADR (assuming a ratio of 2.5 new
ordinary shares to one ADR) would be paid.





* Based on Turkish Central Bank's TRY/US$ exchange rate of TRY1.3447 dated April
6, 2005.
