TSX Approves March Networks' Course Issuer Bid

Ottawa, Ontario – May 26, 2008 –  March Networks® (TSX:MN; AIM:MNW), a leading provider of innovative video and data applications, announced today that the Toronto Stock Exchange (TSX) has accepted the Company’s notice of intention to make a normal course issuer bid. The March Networks’ Board of Directors has approved March Networks’ purchase of up to 1,000,000 common shares (representing approximately 7.24% of March Networks’ public float). The normal course issuer bid will commence on May 29, 2008 and will terminate on May 28, 2009 or on such earlier date as March Networks has purchased the maximum number of shares permitted under the bid. As of May 23, 2008, March Networks had 18,177,340 common shares outstanding and its public float was 13,818,167 common shares.

March Networks expects to use cash and short term investments to fund the repurchase of shares. Purchases under the bid will be made on the open market by March Networks through the facilities of the TSX at the prevailing market price at the time of the transaction. Purchases under the bid may be made at any time during the twelve month period subject to the rules and regulations of the TSX. All shares acquired by March Networks under the bid will be cancelled. March Networks has not previously entered into a normal course issuer bid. The average daily trading volume of the common shares of March Network for the six months ended April 30, 2008 was 47,478 common shares. In accordance with the rules of the TSX, the maximum number of common shares that can be purchased on a daily basis by the Company is 11,869 common shares, subject to the block purchase exception.
 
Management and the Board of Directors of March Networks believe that the market price of March Networks’ common shares during the proposed purchase period of the bid may be such that the purchase of common shares by the Company would be an appropriate use of available funds of the Company and that the purchase of up to 1,000,000 common shares under the bid would, therefore, be in the best interests of the Company.
 
“In addition to our on-going strategic plans for investments in mergers and acquisitions and in research and development to build organic growth, we are of the view that a share repurchase program at this time will be an effective use of the Company’s financial resources,” said Peter Strom, President and Chief Executive Officer of March Networks.
