Securities Information
March Networks Corporation’s shares are listed on AIM (MNW) in London and the TSX (MN) in Toronto. As of July 31, 2007 March Networks Corporation had 16,880,907 common shares in issue, none of which were held in treasury. Insofar as March Networks Corporation is aware, 19.36% of the Company’s shares are ‘not in public hands’ (as defined in the AIM Rules). Based on information available to the Company through the TSXConnect data service and insider filings, the following would be considered “significant shareholders” under the AIM rules as of July 31, 2007:

* “Significant shareholders” under the AIM rules means holders of 3% or more of March Networks Corporation’s issued share capital. As a corporation incorporated under the Canada Business Corporations Act, March Networks Corporation 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 disclosure to March Networks Corporation 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.

March Networks Corporation’s shares are fully fungible between AIM and the TSX and currently all outstanding shares are free trading. March Networks Corporation’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.
