Montreal, Canada; Bellevue, Wash., February 14, 2000 - Microcell Telecommunications Inc. (TSE: MTI.B; Nasdaq: MICT) and VoiceStream Wireless Corporation (Nasdaq: VSTR) jointly announced today that they signed a definitive agreement in which VoiceStream, a leading provider of personal communications services in the United States, agreed to invest CAN$400 million to purchase 9,590,000 newly issued Class A Shares of Microcell. The execution of this definitive agreement follows an agreement in principle reached earlier in January. The per share transaction price was equal to the closing market price of Microcell's publicly traded Class B Non-Voting Shares on the Nasdaq National Market System on January 6.

If fully converted, these Common Shares would represent a 22.6% voting interest in Microcell.
