| TIW to Increase its Ownership of MobiFon S.A. and CESKY Mobil A.S. 
 Telesystem International Wireless Inc. ("TIW") is
 pleased to announce that it has entered into an agreement to acquire
 5.9% of MobiFon S.A. ("MobiFon") from Emerging Markets Partnership
 (Europe) Limited, an affiliate of Emerging Markets Partnership
 ("EMP"), in exchange for the issuance of 12,971,119 common shares of
 TIW representing an equity interest of approximately 11.0% in TIW. The
 number of TIW shares to be issued in exchange for the MobiFon shares
 has been established on an economic equivalency basis. Upon the
 closing of the transaction as agreed, TIW will increase its equity
 interest in MobiFon from 50.1% to 55.9%.
 The transaction is subject to other MobiFon shareholders' pro rata
 rights of first refusal which, if exercised, will reduce the actual
 number of shares to be acquired by TIW. At a minimum, TIW will acquire
 a 3.6% interest in MobiFon in exchange for 7,947,820 common shares of
 TIW.
 Emerging Markets Partnership, a global private equity firm,
 manages investment funds with almost US$ 6 billion in assets. Its
 interest in MobiFon was funded from its US$ 550 million AIG Emerging
 Europe Infrastructure Fund. EMP also indirectly holds a 14.0% interest
 in TIW Czech N.V. ("TIW Czech"), the holding company through which TIW
 owns Cesky Mobil a.s., its operating subsidiary in the Czech Republic.
 As part of the transaction, EMP will rebalance its holdings in TIW
 Czech by agreeing to sell to TIW some of its shares in TIW Czech in
 order that EMP's direct and indirect equity ownership in TIW Czech
 will not change. The number of TIW Czech shares that TIW will acquire
 depends on the extent to which other MobiFon and TIW Czech
 shareholders exercise their respective rights of first refusal. If
 none of those rights of first refusal are exercised, TIW will acquire
 from EMP a 2.9% equity interest in TIW Czech for a cash consideration
 that EMP has agreed to reinvest into 1,650,595 additional TIW common
 shares. This represents an additional equity interest of approximately
 1.2% in TIW, thereby bringing EMP's aggregate equity interest in TIW
 to approximately 12.2%. TIW would therefore increase its equity
 interest in TIW Czech from 21.0% to 23.9% upon the closing of the
 transaction.
 "We are please to have EMP become one of our major shareholders.
 This is also an important milestone in the continuing simplification
 process of TIW's corporate structure, pursuant to which we continue to
 seek opportunities to increase our economic interest in our
 subsidiaries", said Bruno Ducharme, President and Chief Executive
 Officer of TIW. "EMP is delighted to become a core shareholder of TIW
 and looks forward to continuing its fruitful long-term relationship
 with it", said Thierry Baudon, Chief Executive Officer of Emerging
 Markets Partnership (Europe) Limited.
 The terms of the agreement restrict EMP's ability to resell its
 TIW shares for a period of six months following closing of the
 transaction. The transaction is subject to EMP becoming a party to the
 existing investor rights agreement among affiliates of Telesystem
 Limited, J.P. Morgan Partners, LLC and Hutchison Whampoa Limited. TIW
 also expects a representative of EMP to join its board of directors
 shortly after completion of the transaction.
 The closing of the transaction remains subject to certain
 conditions including the execution of final documentation and
 regulatory approval and is expected to take place toward the end of
 the first quarter of 2004. After closing, ClearWave N.V., an 86.8%
 owned subsidiary of TIW and MobiFon Holdings B.V. a wholly-owned
 subsidiary of ClearWave N.V., will become the respective record
 holders of the TIW Czech and MobiFon shares to be acquired in this
 transaction.
