MONTREAL, April 24 /CNW Telbec/ - Montreal Exchange Inc. (TSX: MXX) announced today its financial results for the first quarter ending March 31, 2007.

Revenues for the first quarter reached $21.9 million representing an increase of 15% compared to $19.1 million for the first quarter 2006, due principally to increased market trading volumes. The average daily trading volume was up 26% year-over-year.

Adjusted net earnings for the first quarter 2007, excluding a $2.1 million charge net of tax relating to non-recurring professional fees in connection with the preparation of our non-offering prospectus and the listing of our shares, increased 38% to $7.6 million compared to $5.5 million for the first quarter 2006, excluding a $0.6 million charge net of tax relating to legal settlements in connection with the closing of our trading floor.

"We are pleased with this quarter's results which represent another strong period in our continued growth in the derivatives business," commented MX President and Chief Executive Officer, Luc Bertrand. "There is a very positive operating environment for the derivatives industry in Canada and globally. The Montreal Exchange is a key player with leading-edge technology and excellent growth opportunities from our strategic alliances: BOX, MCeX and CAREX."

"This has been a momentous quarter for us," added Mr. Bertrand, referring to significant recent developments that occurred during the first quarter of 2007.

Recent Developments:

- On March 13, 2007, MX and NYMEX Holdings Inc. ("NYMEX") entered into an
  agreement whereby NYMEX purchased on March 23, 2007, 3,097,718 newly-
  issued MX common shares, representing 10% of MX's outstanding share
  capital after giving effect to this issuance, for $29? per common
  share, totalling net proceeds of $89.7 million (net of transaction
  fees).

- As part of this agreement, MX and NYMEX created a business venture,
  called Canadian Resources Exchange Inc. ("CAREX"), for the trading and
  clearing of different energy products in the Canadian market. Under the
  terms of this agreement, MX and NYMEX each invested $2.0 million in the
  new entity in order to fund initial working capital requirements. MX
  and NYMEX will share CAREX's net earnings equally and control will be
  exercised jointly.

- On April 12, 2007, MX paid a special dividend of $0.33? per common
  share ($9.3 million in aggregate) to shareholders of record on
  March 22, 2007.

  on March 23, 2007 and ending on March 22, 2008, to purchase, in the
