Securities Information

Sandvine’s shares are listed on AIM (SAND) in London and the TSX (SVC) in Toronto. As of January 31, 2007 Sandvine had 137,147,376 common shares in issue, none of which were held in treasury. Insofar as Sandvine is aware, 18.9% of the Company’s shares are ‘not in public hands’ (as defined in the AIM Rules). Based on the best information available to the Company, including through the TSXConnect data service and insider filings, the following would be considered “significant shareholders” under the AIM rules as of January 31, 2007*:

Fidelity Management & Research	14.4%	19,801,788
Celtic House Venture Partners Fund IIA LP	9.1%	12,512,427

* “Significant shareholders” under the AIM rules means holders of more than 3% or more of Sandvine’s issued share capital. As a corporation incorporated under the Business Corporations Act (Ontario), Sandvine is not subject to the provisions of the Disclosure and Transparency Rules (U.K.) of the U.K. Financial Services Authority and, consequently, shareholders would not ordinarily be subject to any U.K. requirement to disclose to Sandvine the level of their interests in common shares. As there are no statutory obligations on shareholders (other than insider and early warning reporting obligations) to disclose to the Company the level of their interests in common shares, the holdings described above may not be accurate.

Sandvine’ shares are fully fungible between AIM and the TSX and currently all outstanding shares are free trading. Sandvine’s common shares have not been registered under the United States Securities Act of 1993, as amended (the “U.S. Securities Act”), or any U.S. state securities laws. Subject to certain exceptions, none of the common shares may be offered or sold, directly or indirectly, in the United States. Offers and sales of any of the common shares in the United States would constitute a violation of the U.S. Securities Act unless made in compliance with, or not subject to, the registration requirements of the U.S. Securities Act or an exemption therefrom.
