                                  ALTAREX CORP.
                            1998 FIRST QUARTER REPORT




To our Shareholders:

     AltaRex continues to implement its strategy of accelerating progress in
achieving corporate partnering, clinical trial execution, and ultimately U.S.
market commercialization of its cancer immunotherapeutic drugs from its
Anti-idiotype Induction Therapy (AIT(TM)) technology platform. AIT(TM)
technology is the Company's proprietary murine antibody approach designed to
induce the human immune system to mount a highly effective anti-tumor response.

     AltaRex is now a highly focused immunotherapy company and as a result of
this strategy, the Company has declined its North American option for
Treosulfan, a patent-expired chemotherapeutic product registered in Europe to
MEDAC GmbH of Hamburg, Germany. AltaRex has also discontinued most of its
research efforts in ImmunoRadio Therapy (IRT(TM)), ImmunoPhotodynamic Therapy
(IPT(TM)) and diagnostics. The Company will now commit its resources to areas
where cancer patients and shareholders will share the greatest potential
rewards.

     AltaRex currently has four AIT(TM) based immunotherapeutic products for
solid tumors in various stages of research and clinical development. These
include its OvaRex(TM) product for ovarian cancer, its BrevaRex(TM) product for
breast cancer, its GivaRex(TM) product for colorectal cancer and its
ProstaRex(TM) product for prostate cancer. The Company believes that one or more
of these AIT(TM) products could also be effective for lung, stomach and
pancreatic cancers.

     Key milestones for AltaRex include the initiation in mid-1998 of an open
Phase II OvaRex(TM) trial for the treatment of ovarian cancer patients with
evaluable disease. This Canadian trial is scheduled to be completed by mid-1999
and will be conducted concurrently with the ongoing North American OvaRex(TM)
trial. The Company believes that the results from this trial will help to
support its corporate partnering efforts and will add additional prospective
clinical and surrogate marker data to an already rich data base compiled from a
retrospective analysis of patients treated with an earlier OvaRex(TM) product in
Germany.

     AltaRex has recently amended its potentially pivotal North American Phase
IIb trial in order to complete the trial in three years, or in the first half of
2001. The U.S. arm of these trials began patient treatment in early April. As of
mid-April, the Company had six centers with Institutional Review Board (IRB)
approval in the U.S. and expects to have eighteen by the end of June 1998. As of
mid-April, approximately 65 patients had been entered into the Canadian arm of
the trial.

     AltaRex presently plans to initiate a Phase I U.S. OvaRex(TM) trial with
cell culture based murine antibody in early 1999. This trial will be designed to
allow the Company to establish safety and preliminary bio-equivalence to its
current "ascites" based murine antibody product. The Company also expects to
initiate a Phase I North American trial for its BrevaRex(TM) product (cell
culture based material) in the second half of 1998.

     During the quarter, AltaRex presented BrevaRex(TM) related research at the
annual meeting of the American Association for Cancer Research. Results of the
research demonstrated the presence of both a humoral and cellular anti-idiotypic
immune response after a series of injections into breast cancer bearing mice,
providing further promise of success for the Company's AIT(TM) technology
platform. The significance of these findings is that we were able to elicit a
measurable idiotypic immune response that may ultimately be applied to the
treatment of breast cancer in women.

     During the first quarter the Chairman announced the appointment of Georges
Hibon to its Board of Directors. Mr. Hibon previously held the position of
Chairman and CEO of Pasteur Merieux Connaught North America. The appointment of
Mr. Hibon adds significantly to the strength of the board.

     In order to gain exposure to the crucial U.S. market, AltaRex will commence
operations from a subsidiary located in Waltham, MA, just outside of Boston. A
number of AltaRex professionals will, over the next four months relocate and
direct business development, clinical, regulatory, contract manufacturing, and
investor relations efforts from this location. Research, early product
development and supporting staff, totaling over 35 individuals, will remain in
Edmonton, Alberta, Canada. The Waltham office was operational on May 11th.

     The Company continues to make important progress and will report
periodically on key milestones achieved in the coming 12-18 months. AltaRex has
launched its corporate web site under the address WWW.ALTAREX.COM, and will
continue to update shareholders via this site.

FINANCIAL HIGHLIGHTS

     For three months ending March 31, 1998, revenues were $260,000 compared
with $188,000 for the same period in 1997. The higher revenues in 1998, which
are derived mainly interest income, are primarily attributed to higher interest
rates.

     The net loss for the three months ending March 31, 1998 was $2.5 million or
$0.15 loss per share compared to $722,000 or $0.05 loss per share for the same
period in 1997. The increased loss reflects the cost of supporting a higher
level of activity in 1998 related to research, product development and clinical
trials. This includes costs associated with the advancement of our potentially
pivotal North American Phase IIb OvaRex(TM) trial.

     The cash and short-term investments balance as at March 31, 1998 was $22.6
million compared with $26.5 million on March 31, 1997 and $25 million on
December 31, 1997.
