MDN Launches a Normal Course Issuer Bid

MONTREAL, QUEBEC, Mar 24 (MARKET WIRE) --
MDN Inc. (TSX: MDN) announced today that the Toronto Stock Exchange
("TSX") has accepted a notice filed by MDN of its intention to make a
normal course issuer bid.

MDN currently has 95,325,410 common shares outstanding. The notice
provides that under the normal course issuer bid, MDN may purchase up to
7,500,000 common shares, being approximately 10% of the public float as
of March 12, 2009 which represents 78,029,792 common shares. In addition
the aggregate number of shares that MDN may purchase during any trading
day will not exceed 35,174 shares, being 25% of the average daily trading
volume of the shares based on their trading volume on the TSX for the
most recently completed six calendar months preceding the date of the
notice of intention which was 140,699, subject to MDN's ability to make
"block" purchases through the facilities of the TSX in accordance with
the TSX rules.

MDN has not purchased any of its shares during the past 12 month period.
The normal course issuer bid will commence on March 26, 2009 and will
terminate on March 25, 2010, or on such earlier date as MDN may complete
its purchases under the bid. The common shares will be acquired through
the facilities of the TSX and the purchase and payment for the shares
will be made in accordance with the requirements of the TSX and all other
applicable laws. The price paid for any common shares acquired will be
the market price of the shares at the time of acquisition. All shares
acquired under this bid will be cancelled. National Bank Financial Inc.
will make the purchase on the open market on behalf of MDN.

The Board of Directors of MDN believes that the purchase by MDN of its
own common shares may, in appropriate circumstances, be a responsible
investment of funds on hand.

An Advisory Opinion dated July 29, 2008, was prepared by Haywood
Securities Inc. ("Haywood") in connection with the exchange offer of MDN
dated July 31, 2008 to purchase all its outstanding listed common share
purchase warrants. Haywood concluded that an exchange ratio of
approximately 3.75 warrants per common share was necessary to provide for
a high probability of participation in the exchange while minimizing
dilution to current MDN's shareholders. Dilution from the warrant
exchange offer at a ratio of 3.75 warrants per common share, when
compared against the dilution upon exercise of warrants, was considerably
less and considered a savings to shareholders given management guidance
and market valuation of comparable companies. MDN also obtained a
Liquidity Assessment and Statement prepared by Fraser Mackenzie Limited
("Fraser Mackenzie") in connection with the exchange offer. Fraser
Mackenzie was of the opinion that the market for the common shares and
warrants was liquid when compared with other similar companies and that
the market for the common share and warrants was not going be materially
less liquid following the completion of the exchange offer.
