CALCULATION OF FILING FEE

Transaction Valuation (1)	Amount of Filing Fee (2)
U.S.$59,745,021	U.S.$2,348

(1)	Estimated solely for purposes of calculating the filing fee. The Transaction Valuation was calculated on the basis of (i) the offer price of (x) €8.50 for each of the 579,559 ADSs outstanding as of January 5, 2009; (y) €8.50 for each of the 2,849,134 Shares estimated to be held by U.S. holders as of December 15, 2008 within the meaning of Rule 14d-1(d) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”); (z) €31.93 plus unpaid accrued interest for each of the 462,939 OCEANEs estimated to be held by U.S. holders as of December 15, 2008; and (ii) an exchange rate (using the noon buying rate in New York City for cable transfers in euro as certified for customs purposes by the Federal Reserve Bank of New York on January 5, 2009) of $1.36 for one euro. The number of Shares and OCEANEs estimated to be held by U.S. holders is based on an assumption, made solely for purposes of calculating the filing fee, that 18% of the 15,828,524 outstanding Shares, as of December 15, 2008, and 18% of the 2,571,884 outstanding OCEANEs, as of December 15, 2008, are each held by U.S. holders and that, for purposes of calculating the amount of unpaid accrued interest only, settlement for the OCEANEs will occur on March 5, 2009.
(2)	The amount of the filing fee, calculated in accordance with Rule 0-11 under the Exchange Act and Fee Rate Advisory No. 6 for the fiscal year 2009, equals U.S.$39.30 per U.S.$1,000,000 of transaction valuation.
þ	Check the box if any part of the fee is offset as provided by Rule 0-11(a)(2) and identify the filing with which the offsetting fee was previously paid. Identify the previous filing by registration statement number, or the Form or Schedule and the date of its filing.

Sierra Wireless holds 84.32% of Wavecom capital and 90.57% of
voting rights before the reopening of the subsequent offering
period

Wavecom announces the early redemption of the OCEANEs

Vancouver, Canada and Issy-les-Moulineaux, France — February 25, 2009 — Sierra Wireless (NASDAQ: SWIR — TSX: SW), a leading provider of wireless solutions for mobile computing, and Wavecom (Paris: AVM — NASDAQ: WVCM), a leading provider of embedded wireless technology for M2M (machine-to-machine) communication, confirmed today that the all-cash tender offers of Sierra Wireless France, a wholly owned subsidiary of Sierra Wireless, Inc., for Wavecom securities in France (the “Offer”) and the United States (the “U.S. Offer”) (together with the Offer, the “Offers”) were successful.

The final results of the Offers were published today by the French stock market authority, the AMF (Autorité des marchés financiers). As of the expiration date of February 12, 2009, 13,353,912 ordinary shares were tendered to the offers (including ordinary shares represented by American Depositary Shares, the “ADSs”), which represent 84.32% of outstanding Wavecom shares. In addition, 2,571,022 OCEANE convertible bonds (the “OCEANEs”) were tendered to the offers, which represent 99.97% of the outstanding OCEANEs. The tendered securities represent 90.57% of the voting rights of Wavecom, and therefore, the minimum tender condition of the Offers has been satisfied.

The settlement of the French tender offer and cash payment to financial intermediaries for the ordinary shares and OCEANEs tendered into the French Offer is scheduled for March 3, 2009. Cash payment for securities tendered into the U.S. Offer is scheduled to occur shortly thereafter.

Subsequent Offering Period from March 11 to 31, 2009

Sierra Wireless announces, subject to the publication of a calendar of the subsequent offering period in France by the AMF, a subsequent offering period in France and the United States starting on March 11, 2009, and which will be open for a period of 15 trading days. Sierra Wireless France has irrevocably undertaken to accept all ordinary shares, American Depositary Shares (“ADSs”) and OCEANEs tendered in the subsequent offering period. The offer price for the ordinary shares is

€8.50 per share, and the offer price for the OCEANEs is €31.93 plus unpaid accrued interest (calculated pro rata to the number of days from the last interest payment date to the day of settlement for the OCEANEs) per OCEANE. The offer price for the ADSs is the US dollar equivalent of €8.50 per ADS.

Shortly after the closing of the subsequent offering period, provided applicable legal requirements are satisfied, Sierra Wireless France intends to implement a squeeze-out of the shares and OCEANEs that have not been tendered to the offers and to request the delisting of Wavecom shares and OCEANEs from Euronext and ADSs from NASDAQ.

Early Redemption of OCEANEs at the Option of OCEANE Holders Following a Change in Control

In accordance with the terms of the OCEANEs as described in Section 4.9.4.2 of the note d’opération, the OCEANE offering prospectus, which received AMF visa n°07-242 on July 5, 2007, Wavecom is hereby announcing the change of control of Wavecom following the success of the Offers initiated by Sierra Wireless France for all Wavecom ordinary shares, ADSs and OCEANEs. Accordingly, non-U.S holders of Wavecom OCEANEs may request early redemption of their OCEANEs during one of the two periods described below.

The first early redemption period will be open from March 4, 2009 to March 9, 2009 at a price of €31.30 plus €0.10505 corresponding to the unpaid accrued interest from the last interest payment date preceding the early redemption date until the effective date of the redemption, i.e. €31.40505 per OCEANE. The early redemption will take place on March 12, 2009.

A second early redemption period is scheduled to be open from April 15 to April 30, 2009 at a price of €31.30 plus unpaid accrued interest from the last interest payment date preceding the early redemption date until the effective date of the redemption. The early redemption is scheduled to take place on May 6, 2009. The final calendar of the second early redemption period, as well as the redemption price will be confirmed later.

U.S. holders (within the meaning of Rule 14d-1(d) under the United States Securities Exchange Act of 1934) may not participate in the two early redemption periods, but all holders, including U.S. holders, may tender their OCEANEs during the subsequent offering period at a price of €31.93 plus unpaid accrued interest, a price higher than the price offered in the early redemption procedure.

Wavecom also reserves the right, in accordance with the terms of the OCEANEs, to carry out an early redemption of the OCEANEs (at a price of the nominal value plus interest accrued from the last interest payment date preceding the early redemption date until the effective date of redemption) if the number of OCEANEs remaining outstanding is less than 10% of the number of the OCEANEs issued. Since only 0.03% of the OCEANEs remain outstanding, as of the expiration date of February 12, 2009, Wavecom hereby informs OCEANE holders that it intends to exercise this right, in the event that Sierra Wireless France is not able to implement a squeeze-out.
