     ALTAREX ANNOUNCES FINANCIAL RESULTS FOR FOURTH QUARTER AND YEAR ENDED
                                DECEMBER 31, 2002

WALTHAM, MA, APRIL 9, 2003 - ALTAREX CORP. (AXO.TO, ALXFF.OTC) announced its
financial results for the fourth quarter and year ended December 31, 2002. All
dollars reported are Canadian.

The Company recorded a net loss of $0.8 million, or $0.02 per share, for the
three months ended December 31, 2002 compared to a net loss of $10.1 million, or
$0.31 per share, for the same period in 2001. For the year ended December 31,
2002, the Company recorded a net loss of $8.5 million, or $0.20 per share,
compared to a net loss of $33.8 million, or $1.21 per share, for the same period
in 2001. The decreased net loss for each of the 2002 periods primarily reflects
the April 17, 2002 license to United Therapeutics Corporation of the Company's
OvaRex(R) and certain other MAb products for North America, Japan, and other
countries, United's assumption of ongoing development responsibilities and
associated expenses of OvaRex(R) MAb in the licensed territory, United's hiring
of certain former personnel of the Company and a resulting significant decrease
in the Company's research and development and supporting general administrative
expenses in the third and fourth quarters of 2002.

At December 31, 2002, the Company's cash, cash equivalents and short-term
investments totaled $3.6 million as compared to $9.1 million at December 31,
2001. The Company believes that its available cash and cash equivalents and
interest earned thereon should be sufficient to finance its operations and
capital needs into the third quarter of 2003. The Company is currently pursuing
corporate alliances and financing options in order to raise the cash required to
continue to fund its operations.

AltaRex Corp. is focused on the research, development and commercialization of
foreign antibodies that modulate the immune system for the treatment of certain
cancers and other diseases where there exists an unmet medical need. Additional
