Notice of Cancellation of AIM

    March Networks Corporation (the "Company") - Notice of Cancellation of AIM
Listing
 
    OTTAWA, June 12 /CNW Telbec/ - The Company hereby notifies that,
following a review of the Company's AIM listing by its Board, the Company has
decided to cancel the admission of its common shares to trading on AIM with
effect from 7.00 a.m. BST on 11 July 2008 (the "Cancellation Date"). The last
trading day on AIM will be 10 July 2008.
    Given the Company's Canadian focused shareholder base, the Board
concluded that the additional costs incurred in maintaining a second listing
on AIM were inappropriate. Due to the relatively low number of the Company's
shareholders holding shares on the Depositary Interest register and the low
volume of trading in shares on AIM, when compared with the regulatory and
financial commitment required to maintain an AIM listing, the Board of the
Company considers it in the best interests of the Company to seek a
cancellation of its shares from trading on AIM. The relatively low profile of
the Company on AIM, together with its low level of trading and the costs and
inconveniences associated with an AIM listing, result in the Board's opinion
that such a listing cannot be justified.
    The Company will still be maintaining its listing on the Toronto Stock
Exchange ("TSX") and shareholders wishing to trade the Company's Common Shares
after the Cancellation Date will be able to do so through that market.
Shareholders should not therefore be materially prejudiced by the proposed
cancellation of the AIM listing.
    Depositary Interest holders should, within 90 days of receiving notice
from the Company's UK transfer agents Computershare Investor Services PLC
("Computershare") of the termination of the Depositary Agreement, submit in
the normal manner a "CREST Withdrawal form" and notify Computershare how they
wish to deal with their shares. If the shares are to be held through a
CDS Broker you will need to supply the CDS Deposit Reference of your agent in
Canada.
    Upon cancellation of the AIM listing, your Depositary Interests will be
transferred into a certificated holding unless you have submitted a
CREST Withdrawal form as mentioned above.
    We encourage you to migrate your holding from AIM/Crest to TSX as soon as
practical.
    Shareholders are advised to consult their stockbroker, bank manager,
solicitor, accountant or other independent professional adviser for the
procedure to follow to transmit their shares to the Canadian shareholder
register, or to contact Computershare Investor Services PLC, the Pavillions,
Bridgwater Road, Bristol BS13 8AE, United Kingdom, Telephone: [phone]
0000, www.computershare.com web.queries(at)computershare.co.uk for the
procedure to follow. For those not familiar with the Canadian securities
system, public information on the Company can be accessed through

made.
