                "Improving Macro Environment Boosts Performance"

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





Comments from the CEO, Muzaffer Akpinar
-------------------------------------------------------------------------------
For Turkcell, 2003 was a very successful year in operational terms. Although the
year started with uncertainty due to regional instability, the conclusion of the
war in Iraq and improving macroeconomic conditions yielded a better than
expected operational environment for us. We began to reap the fruits of economic
reforms in Turkey, as inflation dropped to record-low levels, consumer sentiment
continued to strengthen and 2003 GDP grew by 5.9%.

After a third quarter that registered record-high quarterly revenues, growth in
the fourth quarter slowed due to seasonality. Our customer-focused approach
continued and we believe our achievement in this area directly affected our
churn figures, recording a low 14.5% churn for the year in a four operator
environment. Our strategic focus on segmentation, award winning Customer
Relationship Management capabilities, offering services tailored to the needs
and expectations of our different customer groups, made it possible to expand
our subscriber base by 21% to 19 million, a net addition of 3.3 million
subscribers for the year.

Unfortunately, Turk Telekom's decision in the second quarter of 2003 to withhold
interconnection payments has been a burden. Although we signed a new
Interconnection Agreement on September 20, 2003, resolving the dispute regarding
pricing terms, the retroactive claims of Turk Telekom continue and the issue has
been escalated to Administrative courts in Turkey. This means that the
conclusion of this dispute is further extended as the legal cycle will start
generally from the beginning.

On April 20, 2004, we announced that a federal judge has approved the settlement
of the consolidated securities class action lawsuit filed against the Company
and several of its past and present officers and directors in the U.S. District
Court for the Southern District of New York. Under the terms of the settlement,
all claims against the Company have now been dismissed without admission of
liability or wrongdoing. The shareholder class is receiving a cash payment of
US$19.2 million. Although we believe the plaintiffs' claims are without merit,
we are pleased to put the uncertainty and expense of the litigation behind us
and the decision to settle is in the best interest of our shareholders.

On the local front two major disputes remain, the call termination charge
dispute (interconnection) with Turk Telekom, which was mentioned above, and the
conflict with the Turkish Treasury regarding the calculation of the treasury
share payment. These cases are ongoing, and we cannot estimate when they will
end or what their ultimate resolution will be. We continuously assess the level
of risk involved in our cases with our legal advisors. Accordingly, as of year
end 2003, we decided to revise our level of net legal provisions related to
these two ongoing cases and now have, in total, US$1,181 million of net legal
provisions. Our estimates of the required provisions are based upon an analysis
of potential outcomes to these cases, assuming a combination of litigation and
settlement strategies. If the actual costs associated with resolving these
disputes differ from our estimates, our future financial results may be
materially, adversely affected.

                                                                              2



Despite the increased legal provisions provided in the fourth quarter, Turkcell
has significantly enhanced its financial standing and fulfilled its financial
commitments throughout the year. We have improved our debt structure by
decreasing the cost of funding and extending the average maturity of our debt in
line with our guidance provided early in the year.

Also in 2003, in line with our strategic intentions, we concentrated our efforts
on finding new frontiers to further expand our business. In this context, we bid
for and became licensee of the GSM license in Iran and signed a GSM partnership
in Ukraine. We believe that these new investment areas will help sustain the
growth of our revenues and create long-term value for our shareholders.
Furthermore, on top of these investments, we plan to spend approximately US$200
million in 2004 on capital expenditures related to our domestic operations.

We are pleased to have announced net profit based on both the US GAAP and
Turkish Accounting Standards for 2003. This result included the recognition of a
net deferred tax asset of US$458 million under US GAAP during the fourth quarter
of 2003. This asset was recognized after assessing the adequacy of our deferred
tax valuation allowance. Changing conditions in the market place during the
fourth quarter and subsequent to year-end, and the fact that we now believe it
is more likely than not that tax credit carry forwards and other tax assets that
we will be able to use has increased and that we expect to have taxable income
in near term, have allowed us to recognize this net deferred tax asset.

In line with the Capital Markets Board's regulation in Turkey, we have adopted
to the new accounting standards, which comply substantially with International
Financial Reporting Standards ("IFRS") for the local market as of and for the
year ended December 31, 2003. Previously, the accumulated losses in our
financial statements based on the previous Turkish Accounting Standards limited
us from distributing a dividend, whereas the US$803.1 million in net profit
recorded in 2003 diminished this obstacle. Accordingly, this development paved
the way for us to distribute dividend following our Annual General Meeting.

There were a number of changes in our competitive environment during 2003,
namely the Aria-Aycell merger and the change of management control of Telsim.
Competition generally focused on the reduction of prices during the year.
However, we have not directly responded to these price cuts. We emphasized on
our several mass and segmented loyalty programs, volume based campaigns and
offers. Our profit oriented approach coupled with our customer focused
strategies will continue in 2004. Similarly, we expect competition to evolve
along more rational lines, becoming value based rather then solely price based.

In 2004, Turkey faces new challenges. Developments in the Cyprus conflict and
membership in the European Union may affect the macroeconomic environment in
Turkey and market dynamics. Possible developments in Iraq and the region could
have an adverse impact on Turkey's economy and political environment. However,
Turkish macroeconomic indicators are developing positively. The Government's
efforts to comply with the International Monetary Fund and the economic program
are encouraging.

                                                                              3




We will carry on with our customer focused, segmented approach to support our
large subscriber base in 2004. New tariff schemes will continue to be introduced
to ensure satisfaction of different customer groups, while encouraging usage.
Despite having achieved optimized levels of efficiency in our cost base, we will
continue to remain focused on the bottom-line, going forward.

Assuming no major material impact as a result of the uncertainties we have
outlined above, we believe that the transformation in our sector and further
economic stability could provide a favorable operating environment for us. We
therefore have a positive outlook for 2004.

The summary financial data below reflects the full effect of the additional net
legal provisions provided and the deferred tax assets recorded during the fourth
quarter of 2004. For discussion purposes, later in the financial review section

Legal Provisions

Turkcell's net legal provision was US$1,181 million as of December 31, 2003
compared to US$347 million as of December 31, 2002. Based on the factors
discussed below, an additional provision of US$539 million was recorded during
the fourth quarter of 2003.

Turkcell had not previously made any provision with
respect to the interconnection revenue dispute with Turk Telekom (i.e.
interconnection dispute). However, due to

                                                                              4




ongoing uncertainties regarding the case, Turkcell management has decided to
establish a provision of US$462 million, including interest, related to this
case as of December 31, 2003. Our estimate of the amount required to resolve
this dispute is based upon an analysis of potential results, assuming a
combination of litigation and settlement strategies. There can be no assurance
that our assumptions will prove to be correct. If our assumptions are wrong or
the actual costs associated with resolving the dispute differ from our
estimates, our future financial results may be materially, adversely affected.
The period under consideration for determining the provision for the
interconnection dispute is between November 2000 and September 2003. Turkcell
signed a new Interconnection Agreement with Turk Telekom on September 2003,
which has revised the pricing terms and clarified the issue going forward.

The principal portion of the net provision US$240 million, has been deducted
from the interconnection revenues. Additionally, interest on the principal
portion, amounting to US$207 million has been recorded as interest expense and
we recorded a related translation loss of US$15 million due to changes in the
Turkish Lira / USD foreign exchange rates, overall establishing the total
provision of US$462 million.

Additionally, Turkcell has increased its provision amount related to the
Treasury Share dispute to US$516 million at the end of the period. However, the
15% Treasury Share calculation is impacted by the level of interconnection
revenue, we have revised the provision for the Treasury Share case based on our
current views with respect to interconnection revenues.

In this press release, in addition to our US GAAP financial and operational
results, we have provided financial and operational information excluding the
effect of the additional net legal provisions we reorganized during the fourth
quarter. We believe that the results achieved, before the additional net legal
provisions of US$539 million, provide additional data with which to assess the
on-going operational performance of the company.

Strong operating performance

In 2003, Turkcell generated US$2,219 million (US$1,974 million) in revenues and
reported a net profit of US$215 million (US$47 million). This result includes
the effect of additional net legal provisions of US$539 million and US$458
million related to the reversal of the valuation reserve for our deferred tax
asset, each of which were recorded in the fourth quarter. Excluding the impact
of the additional net legal provisions, Turkcell would have reported revenues of
US$2,459 million and net income of US$754 million.

Leaving aside the negative impact of the additional legal provision, Turkcell
had an outstanding year, enhancing earnings attributable to its operating
performance, which were further boosted by the improving economic environment of
Turkey.

Turkcell reduced its net debt, while financial restructuring continued

                                                                              5




Turkcell continued to strengthen its financial structure in the fourth quarter
of 2003, repaying US$400 million in debt. As of December 31, 2003, Turkcell's
gross debt was reduced to US$630 million (US$1,011 million in the third quarter
2003) down from US$1,308 million at the end of 2002. Debt redemptions, including
interest, for the year totaled US$806.2 million.

On November 10, 2003, Turkcell paid US$300 million of the 15% Senior
Subordinated Notes due 2005 of its finance subsidiary, Cellco Finance N.V., its
financing subsidiary. Furthermore, Turkcell repaid an additional US$100 million
of debt in the fourth quarter of 2003.

On September 19, 2003, Turkcell announced that it had mandated HSBC Istanbul
Main Branch ("HSBC") and The Islamic Development Bank ("IDB") to arrange
financing of up to US$100 million with a maturity of two years from each
drawdown of the financing. On January 16, 2004, Turkcell secured the syndicated
Murabaha facility of US$100 million, to be used for equipment purchases.

Turkcell has continued its efforts to lower its cost of borrowing and extend the
maturity profile of its debt. Accordingly, on February 11, 2004, Turkcell raised
a further US$200 million, provided equally by Akbank (US$100 million) and
Garanti Bank (US$100 million), two of the leading private banks in Turkey. Each
of these uncollateralized facilities have a maturity of three years. The Akbank
facility has a total cost of LIBOR plus 3.50%, while the Garanti Bank facility
has a total cost of LIBOR plus 3.40%. Turkcell intends to use these domestic
bank loans primarily to finance investments.

As a result of strong cash generation, Turkcell ended 2003 with US$583 million
(US$696 million as of 3Q 2003) in cash, despite significant debt redemptions in
the fourth quarter.

Subscriber growth continued

On top of the improving consumer sentiment and stabilizing economic environment
in Turkey, Turkcell's emphasis on customer relationship management and churn
prevention resulted in higher than expected subscriber growth in 2003. In the
fourth quarter, Turkcell added 810,801 net new subscribers, raising its total
number of mobile subscribers to 19.0 million from 18.2 million subscribers at
the end of the third quarter. Postpaid subscribers increased to 4.8 million and
the number of prepaid subscribers reached 14.2 million. On a gross basis, new
subscribers acquired in 2003 consisted of 91% prepaid and 9% postpaid
subscribers. The overall share of post-paid subscribers contracted to 25% of all
subscribers in 2003, down from 30% 2002.

The acquisition cost per subscriber ("SAC") decreased to US$28.8 in the fourth
quarter of 2003 from US$29.6 in the third quarter. Nevertheless, growth in SAC
on an annual basis for 2003 remained moderate at US$26.7 compared to US$25.9 in
2002, a 3% increase. This annual increase originated from the campaigns aimed at
both channel and end users.
                                                                              6



Improving consumer sentiment boosted revenues

Turkcell's blended monthly minutes of usage ("MoU") dropped to 57.5 minutes in
the fourth quarter (65.7 minutes) due to seasonality. However, compared to 2002
figures, it is evident that the economic recovery had a positive effect on MoU
in 2003 together with our segmented volume based offers and mass loyalty
programs. In the fourth quarter of 2003, MoU was 9% higher than in fourth
quarter 2002, while the annual figures show that MoU levels improved by 4% in
2003 and reached 58.5 minutes compared to 56.2 minutes in 2002.

In line with the seasonal drop in MoU and the additional net legal provisions,
blended average revenue per user ("ARPU") for the fourth quarter declined by 53%
to US$6.7 compared to the previous quarters US$14.2, while 2003 blended ARPU
decreased by 9% relative to 2002 figure at US$10.6 (US$11.7). The blended ARPU,
before additional net legal provisions dropped to US$11.0 in the fourth quarter,
while the 2003 blended ARPU remained flat at US$11.7.

The impact of the new interconnection agreement, Turk Telekom's non-payment of
interconnection fees and the contraction in the overall share of post-paid
subscribers to 25% in 2003 from 30% in 2002 restricted the impact of increased
MoU on earnings.

Price based competition in 2003

There were two major developments on the competition front during 2003, the
completion of the Aria-Aycell merger and the change of control of Telsim. The
impacts of these developments in the market are yet to be seen. In 2003, all
players continued their focus on price based competition with the aim of
increasing market share. Meanwhile, Turkcell successfully reinforced its
leadership, while not participating price based competition.

The quarterly churn level retreated to 3.14% (3.87%) in the fourth quarter of
2003, while the annual churn level for 2003 was 14.5%. In contrast to last years
figure, the churn level showed a 1.6% point rise, which was better than initial
expectations for the year. Turkcell's proactive approach to churn prevention
through the establishment of churn prevention teams and various campaigns,
developed and introduced as part of these efforts kept subscriber churn under
control.

Customer focus

Turkcell introduced "Shubuo," our mobile interaction platform in June 2003.
Shubuo provides Turkcell subscribers with a choice of several service packages,
each focusing on a different interest area, creating a medium for consumer
brands to promote their goods and services. Shubuo service packages allow
Turkcell to assess interest areas of its subscriber base and accordingly offer
customized services to its customers. Shubuo is expected to further enhance
customer loyalty, while gaining commercial value by providing consumer brands a
medium for reaching their target market more accurately.

                                                                              7




In the fourth quarter of 2003, Turkcell engaged in a series of marketing
campaigns as part of its 10th year anniversary celebrations. Turkcell emphasized
its strengths, contributions to the society and used different platforms to
convey its corporate values to the market. Diversified, mass and segmented
offers were developed and the launches were supported by various media channels,
resulting in higher recognition and overall usage by our subscribers. The
counter transfer capability for prepaid subscribers, ability to place mobile to
mobile collect calls within our prepaid network, scratch card campaigns where
purchase of scratch cards with higher counters were encouraged and other volume
based campaigns were some of the highlights of offers.

Major legal developments

-------------------------------------------------------------------------------
Dispute with Turk Telekom on Interconnection Fee Structure
-------------------------------------------------------------------------------

The Turkish Electrical Engineers' Society commenced a lawsuit against Turk
Telekom in 2000 in the Ninth Administrative Court on the grounds that `'call
termination fees were not symmetric'' and that the interconnection agreement
between Turkcell and Turk Telekom was against public interest. On October 2000,
the court annulled the pricing terms of the agreement, although Turkcell was not
party to the law suit.

On November 20, 2000, Turkcell was informed of the court's decision and received
notification from Turk Telekom that Turkcell should comply with the court's
decision and the sharing of the revenues should be calculated retroactively from
April 1998, the date of the license.

Following this notification, Turk Telekom initiated three separate cases against
Turkcell for three different periods and made a payment claim of TL1,9
quadrillion ($1.3 billion at December 31, 2003).

In response to these claims, Turkcell initiated separate lawsuits for each
period of related claims and an injunction decision was received preventing Turk
Telekom from collecting the claimed amounts. In July 2003, Turkcell obtained a
court decision from a Commercial Court, which stated that Turk Telekom should
continue to comply with original interconnection agreement until a new contract
was reached.

In line with Telecom Authority's ("TA") guidance, Turkcell and Turk Telekom
signed a new interconnection agreement in September 20, 2003 also revising the
pricing terms of the agreement which does not entail equal sharing of the
interconnection fees.

However, Turk Telekom stopped making its monthly interconnection fee payments to
Turkcell for the period of May to December 2003, which amounted to approximately
US$145 million (excluding Value Added Tax ("VAT")) as of December 31, 2003. This
revenue amount was not recorded in Turkcell's 2003 financial statements. Turk
Telekom informed Turkcell that they stopped making the monthly interconnection
fee payments in accordance with an injunction decision from an Ankara Commercial

                                                                               8





Court. The same court had rejected Turk Telekom's similar request of injunction
twice earlier.

Later, the Ankara Commercial Court partially accepted Turkcell's appeal
concerning the injunction decision and lifted the injunction on 30% of the
monthly payments. Accordingly, in January 2004, Turk Telekom started making 30%
of the interconnection fee payments, while the injunction remains effective on
the outstanding 70% for the same dispute.

While the case regarding the essence of this dispute continued in the Ankara
Commercial Court, in February 2004 the Assembly of Civil Law Chambers of Court
of Appeals ruled that the dispute between Turk Telekom and Turkcell concerning
the determination of call termination pricing should be overseen by the
Administrative Courts, determining the legal authority. Such verdict simply
further extended the legal process as the legal cycle will start generally from
the beginning.

-------------------------------------------------------------------------------
Disputes concerning the definition of the gross revenue and the calculation of
the 15% Treasury share
-------------------------------------------------------------------------------

Turkcell is required to pay 15% of its monthly gross revenue, which is defined
in its license agreement as subscription fees, monthly fixed fees and
communication fees, to the Turkish Treasury as part of its license agreement.
However, the Turkish Ministry and the Turkish Treasury informed Turkcell that,
in their view, its 15% ongoing license fee should be calculated before deduction
of VAT, the education fund, the frequency usage, transmission fees and value
added revenues. Turkcell has consistently calculated its 15% treasury share fee
payment after deducting these items, which Turkcell believes is consistent with
the terms of its license.

Turkcell filed a petition with the International Court of Arbitration of the
International Chamber of Commerce ("ICC") for determination of the constituents
of the "gross revenue" item to be used in the calculation of the 15% Treasury
share payment, while the case also continued at local level in the Danistay, the
highest administrative court in Turkey.

On October 2003, the Danistay, rejected Turkcell's claim concerning the
exclusion of certain value-added services, transaction fees, incoming roaming
revenues and interest charges for late collections from the determination of the
15% Treasury share paid to the Turkish Treasury.

In January 2004, the ICC ruled that all the revenue items originating from
telecommunications services should be included in the calculation of gross
revenues, while the taxes collected by Turkcell, as agent for the government
under its "tax responsibility" duties should be excluded.

On February 10, 2004, Turkcell filed an appeal against the Danistay's ruling.
Turkcell also understands that the Treasury of Turkey has challenged ICC's
decision to exclude taxes collected from the calculation of the Treasury Share
payment.

-------------------------------------------------------------------------------
Developments concerning the National Roaming Dispute
-------------------------------------------------------------------------------

                                                                              9




During the third quarter of 2001, Turkcell was approached by IsTim to negotiate
a national roaming agreement. Because these negotiations did not result in a
mutual agreement, Turkcell was required by the TA to continue discussions
towards a solution proposed by the TA under its supervision. As Turkcell
believes that the TA is not authorized to intervene in this issue and that the
TA's proposal was technically impossible and commercially unacceptable, in
November 2001 Turkcell obtained an injunction from Ankara Forth Court of First
Instance prohibiting the execution of a national roaming agreement between
Turkcell and IsTim.

In March 2002, the TA declared that Turkcell was under an obligation to enter a
national roaming agreement with IsTim within a 30 day period. However, Turkcell
still has the benefit of the injunctive relief obtained in November 2001.

Nevertheless, the TA continues to claim that Turkcell has failed to provide
national roaming to IsTim within the legal time frame. Turkcell believes that,
based on its license agreement, it is not obligated to provide national roaming
and that the TA does not have the legal authority to force Turkcell into an
agreement.

On March 26, 2004, Turkcell was assessed a penalty amounting to TL21.9 trillion
(US$16.6 million) from the TA. As the case continues at the local level, before
the Danistay, Turkcell paid the penalty on April 7, 2004.

-------------------------------------------------------------------------------
Telecommunication Authority fined Turkcell claiming inadequate frequency fee
payments and for violating Turk Telekom's monopoly
-------------------------------------------------------------------------------

In October 2003, the TA fined Turkcell, claiming that Turkcell has made
inadequate annual frequency usage fee payments. According to the related
regulations, frequency usage fee claims should arise only for those subscribers
who actively use their mobile phones. However, the TA claimed that Turkcell also
should pay these fees for those subscribers whose inactivity may be temporary.

The amount demanded by the TA totals TL90.2 trillion (US$64.6 million). The TA
demands TL16.0 trillion (US$11.5 million) for insufficient payment, an interest
charge amounting to TL10.8 trillion (US$7.7 million) and an additional amount of
TL63.5 trillion (US$45.5 million) as an administrative penalty. Turkcell
believes that the TA's decision is due to a misinterpretation of the applicable
regulations and that the magnitude of the administrative penalty is surprising.
Turkcell paid the TA's claim on April 6, 2004 and initiated the legal
proceedings against this penalty before the Danistay.

Moreover, in April 2004, the TA once again fined Turkcell, which totaled TL31.7
trillion (US$24.0 million). The TA argued that Turkcell violated its license
agreement and regulations governing Turk Telekom's monopoly by using
infrastructure other than Turk Telekom's for its services. Turkcell paid the
TA's claim on April 9, 2004 and took necessary legal action.

-------------------------------------------------------------------------------
Dispute on Collection of Frequency Usage Fees
-------------------------------------------------------------------------------

                                                                             10




On March 22, 2002, as a consequence of the impossibility in fact and at law of
collecting frequency usage fees that Turkcell is required by the Wireless
Communications General Directorate to collect from its prepaid subscribers,
Turkcell applied to the Ankara 17th Judicial Court and obtained an injunction in
respect of the collection of the fees.

On March 31, 2003, the Supreme Court notified Turkcell that it had accepted the
TA's appeal and annulled the lower court's injunction. Turkcell received a
payment order for the annual frequency usage fee for 2003 amounting to $57.3
million as of December 31, 2003, including interest of $6.5 million. Turkcell
made this payment on May 5, 2003.

Turkcell had not paid the fees for 2002 as of December 31, 2003 but had accrued
$33.0 million for principal and $51 million for interest for the frequency usage
fees of 2002. The payment was made on April 20, 2004


Fintur International
-------------------------------------------------------------------------------

Fintur International continued its strong growth in the fourth quarter and the
GSM businesses in Azerbaijan, Kazakhstan, Georgia and Moldova added 261,000
(239,000) net new subscribers, raising the total number of subscribers to
approximately 2.4 million (1.6 million as of December 31, 2002) as of December
31, 2003. The 2003 annual expansion in the number of subscribers was impressive
at 50%. Furthermore, the 2003 revenues were US$340 million, a 42% increase
compared to the 2002 amount of US$240 million. Profitability also improved.
Turkcell owns 41.45% of Fintur and accounts for its investment using the equity
method.

New International Business Prospects: Iran and Ukraine

Turkcell became licensee for the first private GSM license in Iran

On February 18, 2004, it was announced that the Turkcell-led consortium
("Irancell") made the most attractive offer in the nationwide GSM900/1800
license tender in Iran. Accordingly, once the license agreement is signed and
the payment of (euro)300 million in license fees is made, the consortium will be
awarded the first private GSM900/1800 GSM license in Iran. The signing of the
license agreement is expected to take place upon establishment of the local
company, a process that is underway.

Turkcell currently has a 51% majority control stake in Irancell. The Iranian
mobile market, with approximately 5% mobile phone penetration and a population
of 70 million, presents a major growth opportunity. Insufficient capacity in
mobile communications coupled with high demand has created long waiting lists
and a population in great need of proper service.

The initial direct cash outflow from Turkcell to Irancell is estimated at
(euro)105 million as paid-in capital, while further investment requirements are
planned to be met through bridge financing followed by additional long-term bank
and vendor financing at Irancell. In addition, Turkcell will provide a limited
guarantee for the (euro)210 million bridge

                                                                             11


financing at Irancell to be obtained for Irancell. Irancell is expected to
become operational in 2004.

Turkcell established a partnership in the Ukraine obtaining a nationwide GSM1800
license

On April 2, 2004, Turkcell signed a partnership agreement with the shareholders
of Digital Cellular Communication ("DCC") marking the start of DCC's GSM
operations in Ukraine. DCC is the third largest mobile phone operator in the
Ukraine servicing a network based on the TDMA800 standard, while holding a
nationwide GSM1800 license. As part of the partnership agreement, Turkcell has
invested through a capital contribution US$50 million in the newly established
company in exchange for a 51% stake, while the owners of DCC provided DCC as a
capital-in-kind contribution for the remaining 49% of the partnership. The new
venture will build a nationwide GSM1800 network, which is expected to become
operational within the next 12 months.

Turkcell plans to meet further investment requirements through vendor financing
and bank loans, similar to the plans in Iran. Turkcell plans to establish itself
as one of the major operators in each of these markets through a mass market
approach and upfront investments respective countries.

Annual General Shareholders Meeting
Turkcell will convene its Annual General Shareholders Meeting ("AGM") at
Turkcell Plaza, Conference Room, Mesrutiyet cad. No:153 Tepebasi, Istanbul on
Friday, June 4, 2004, at 15:00. In addition to the ordinary meeting agenda
items, such as the review of 2003 operations, the distribution of the 2003
year-end profit and the registered capital ceiling increase will be discussed.

Dividend
Until this year, Turkcell was legally prohibited from making dividend payments
due to its accumulated balance sheet loss under the previous Turkish Accounting
Standards. However, as of year-end 2003, Turkcell began reporting its financial
results according to the new accounting standards which substantially comply
with International Financial Reporting Standards ("IFRS"), thereby eliminating
the accumulated loss. Accordingly, dividend distribution will be an agenda item
at Turkcell's AGM in June. According to the CMB principles on dividend
distribution, a minimum of 20% of the distributable profit should be distributed
as dividend in either one of the following methods; (i) all in cash, (ii) all in
bonus shares, or (iii) a combination of both cash and bonus shares.

Financial and Operational Review
The following discussion focuses principally on the developments and trends in
Turkcell's business in the fourth quarter of 2003 and year-end 2003 compared to
the third quarter of 2003 and year-end 2002. To aid analysis, selected financial
information for the fourth quarter of 2002 is included at the end of this press
release. The summary table below shows the impact on 2003 income statement items
as a result of additional net legal provisioning recorded and the deferred tax
asset gain in the fourth quarter. In the discussions below, we will refer to the
financial results before new net legal provisions as "pre-adjusted."

                                                                             12

Subscribers
Turkcell added approximately 810,801 (932,362) net new subscribers in the fourth
quarter of 2003 and increased its subscriber base to 19.0 million (18.2 million)
as of December 31, 2003. Prepaid customers dominated the new additions in the
fourth quarter, with 11% of the gross new subscribers in the postpaid segment
and 89% in the prepaid. The same breakdown for the year 2003 was 9% for postpaid
and 91% for prepaid.

The overall subscriber base at December 31, 2003 was comprised of 14.2 million
prepaid and 4.8 million postpaid subscribers.

Revenues
Turkcell posted US$380 million (US$765 million) in revenues for the fourth
quarter, a 50% reduction from the third quarter. This reduction was primarily
attributable to the principal portion of the additional net legal provisioning
of US$240 million. Total 2003 revenues were US$2,219 million (US$1,974 million),
a 12% increase over 2002. Excluding the effects of the increased legal
provisions, revenues were US$620 million for the fourth quarter, implying a 19%
slide due to seasonality, quarter-on-quarter, and US$2,459 million for the year.

Turk Telekom's partial payments continued in the fourth quarter. The total
interconnection revenues not paid by Turk Telekom to Turkcell amounted to US$145
million for 2003. These amounts have not been included in fourth quarter or 2003
revenue.

ARPU
In line with the significant drop in revenues in the fourth quarter, quarterly
postpaid ARPU contracted by 40% to US$19.3 (US$32.1) and prepaid ARPU declined
by 69% to US$2.4 (US$7.8), primarily due to the additional net legal provisions
recorded during the quarter. In 2003, postpaid ARPU climbed 5% to US$24.4
(US$23.3) and prepaid ARPU decreased by 8%, to US$5.4 (US$5.9).

On a pre-adjusted basis, the postpaid ARPU amounted to US$26.0 and prepaid ARPU
totaled US$6.4, remaining below the third quarter figures due to seasonality.

                                                                             13



The blended ARPU dropped to US$6.7 (US$14.2) in the fourth quarter due to the
additional net legal provisions and seasonality, while the pre-adjusted figure
was US$11.0. On an annual basis, the blended ARPU slid by 9% to US$10.6
(US$11.7) for 2003. The pre-adjusted blended ARPU remained flat at US$11.7 in
2003. The dilutive effect of the expansion on the prepaid customer base kept the
pre-adjusted blended ARPU unchanged in 2003, despite the individual developments
in both prepaid and postpaid ARPU.

MoU
Turkcell's blended monthly minutes of usage (MoU) decreased by 13% in the fourth
quarter to 57.5 minutes (65.7 minutes), whereas the 2003 year-end MoU advanced
by 4% to 58.5 minutes, year-on-year. The favorable effect of the improving
macroeconomic environment on consumer sentiment along with Turkcell's segmented
volume based campaigns and mass loyalty programs were the main drivers of the
increase in usage during the annual period.

EBITDA
In the fourth quarter, Turkcell had a negative EBITDA of US$158.4 million
(US$351.1 million in positive EBITDA), while the 2003 EBITDA amounted to
US$642.9 million (US$761.3 million). The pre-adjusted EBITDA for the fourth
quarter was US$234.7 million, representing a quarter-on-quarter decline of 33%,
mainly attributable to seasonality. This quarterly performance brought the
pre-adjusted 2003 EBITDA to US$1,036 million. The overall growth in business
along with tight cost control policies resulted in a favorable operating
performance.

Translation loss
Turkcell realized a translation loss of US$26.3 million (US$22.5 million in
translation loss) in the fourth quarter. As most of the reserves are Turkish
Lira denominated, the rise in total provisions also increased the translation
losses despite the low appreciation of Turkish Lira.

Translation loss for the year 2003 was US$102.4 million (US$18.0 million in
translation loss). The increase was due to higher provisioning and strong
Turkish Lira. Depreciation of the Turkish Lira against the US Dollar was 14.6%
in 2003.

The pre-adjusted translation loss totaled US$10.0 million for the fourth quarter
and US$86.2 million for the year.

Churn rate
Churn refers to disconnected subscribers, whether disconnected voluntary or
involuntary. Turkcell's quarterly churn rate slid by 73-basis points to 3.14%
(3.87%) in the fourth quarter of 2003, bringing the annual figure to 14.5%
(12.9%). On an annual basis, the upswing in churn was better than expected and
climbed by only 1.6-percentage points.

Turkcell believes that it has an adequate bad debt provision in its financial
statements for non-payments and disconnections.

                                                                             14




Profit & Loss And Balance Sheet Statements
-------------------------------------------------------------------------------

Net income

Turkcell posted net income of US$215.2 million (US$47.4 million) in 2003.
Turkcell posted a net loss of US$14.3 million (US$116.8 million in net profit)
for the fourth quarter of 2003. These results include a deferred tax gain of
US458 million recorded during the fourth quarter.

Turkcell had a pre-adjusted net income of US$754.1 million in 2003 and US$524.6
million in the fourth quarter 2004.

Direct cost of revenues

The direct cost of revenues including depreciation and amortization was US$481.5
million for the fourth quarter 2003 (US$441.4 million). Along with the decrease
in revenues, the treasury share and interconnection expenses also declined
compared to the previous quarter. On an annual basis, the direct cost of
revenues for 2003 grew by 18% to US$1,613.2 million (US$1,366.9 million) after
the inclusion of the additional net legal provisions, in line with the increase
in revenues.

The pre-adjusted direct cost of revenues decreased 6% to US$416.4 million for
the fourth quarter. The pre-adjusted direct cost of revenues totaled US$1,548.0
million in 2003.

Depreciation and amortization

Depreciation and amortization expenses remained fairly flat at US$106.4 million
(US$105.1 million) for the fourth quarter of 2003 and at US$421.5 million
(US$411.6 million) for the year.

Selling and marketing expenses

The fourth quarter 2003 selling and marketing expenses climbed to US$120.9
million (US$67.0 million), an 80% increase, while the growth in the 2003 annual
amount was lower at 32%, bringing the total to US$294.6 million (US$223.6
million). The significant increase in selling and marketing expenses was due to
the additional net legal provisioning for the frequency usage fee dispute with
the TA.

The pre-adjusted selling and marketing expenses remained stable at US$65.1
million in the fourth quarter, the 2003 figure increasing to US$238.9 million, a
7% increase year-on-year. This increase in costs was due to periodic campaigns
for the distribution network and end-users and sponsorship expenses related to
the Turkish premier football league.

Acquisition cost per subscriber decreased by 3% to US$28.8 (US$29.6) in the
fourth quarter. For the year 2003, acquisition cost per subscriber increased 3%
to US$26.7 (US$25.9).

General and administrative expenses

                                                                             15




General and administrative expenses almost doubled in the fourth quarter,
amounting to US$58.1 million (US$30.3 million). Moreover, the 2003 general and
administrative expenses reached US$137.2 million (US$104.5 million), a 31%
upswing. The main reason for the increase was the legal provision related to the
finalized class action settlement of US$19.2 million.

Bad debt expense, before deducting collections, as a percentage of revenues, was
2.5% (1.3%) for the fourth quarter of 2003 and 1.8% (3.3%) in 2003.

Equity in net income of unconsolidated investees

Equity in net income of unconsolidated investees was US$5.9 million (US$6.6
million) for the fourth quarter of 2003. Equity in net income of unconsolidated
investees was US$18.9 million (US$20.4 million loss) for the year 2003.

Net interest expense

Net interest expense grew sharply in the fourth quarter due to the additional
net legal provisioning, jumping to US$197.7 million (US$48.9 million).
Accordingly, the 2003 net interest expenses amounted to US$366.3 million
(US$206.8 million), an increase of 77% on a year-on-year basis.

The pre-adjusted net interest expense was US$51.6 million for the fourth quarter
and US$220.4 million for 2003.

Total assets

In the fourth quarter of 2003, Turkcell's total assets increased 6% to
US$3,867.3 million (US$3,652.3 million). Total assets were US$3,233.5 million at
December 31, 2002.

Deferred Tax Asset

Turkcell establishes valuation allowances in accordance with the provisions of
SFAS No 109. We continually review the adequacy of the valuation allowance based
on changing conditions in the market place in which we operate, our projections
of future taxable income and the political and macroeconomic climate in Turkey,
among other factors. We believe that currently, based on a number of factors,
including the likelihood of our recording taxable income in the future, the
current state of the competition in the markets in which we operate, better
political and macroeconomic climate in Turkey in 2003, especially in the fourth
quarter, and in the first quarter of 2004 than 2002, a reduction in political
uncertainty in certain neighboring countries, the available evidence makes it
more likely than not that the amount of tax credit carryforwards and other
deferred tax assets that we will be able to use has increased. We forecast to
have enough taxable income in the near-term future to use a substantial portion
of tax credit carryforwards and other deferred tax assets consisting principally
of those arising from provisions for legal claims, which increased significantly
in the fourth quarter of 2004 due to additions to such provisions. Accordingly,
we released approximately US$458 million of valuation

                                                                             16




allowance in the fourth quarter of 2004 and reported a comparable amount of
deferred tax benefit. However, the amount of deferred tax asset considered
realizable may be reduced if estimates of future taxable income significantly
decrease. We will continue to evaluate the realizability of our deferred tax
assets including net operating carryforwards and tax credit carryforwards and
the related impact on the valuation allowance.

Capex
Capital expenditures in the fourth quarter of 2003 were US$44.2 million (US$39.0
million), while the total figure for 2003 was US$172.9 million (US$71.2
million).


Debt
As of December 31, 2003, Turkcell had a total indebtedness of US$630.2 million
(US$1,011.3 million).


Reconciliation of Non-GAAP Financial Measures

The SEC recently adopted new rules regarding the use of non-GAAP financial
measures. We believe that EBITDA, a measure commonly used in the
telecommunications industry, can enhance the understanding of our operating
results. 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.
