             SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS
             -------------------------------------------------

Certain statements in this Registration Statement constitute "forward looking
statements". Such forward looking statements involve known achievements of the
Company, or industry results, to be materially different from any future
results, performance or achievements expressed or implied by such forward
looking statements. These factors include, but are not limited to: the
Company's early stage of development; the fact that the Company's technology is
in the research stage and therefore its potential benefits for human therapy are
unproven; the possibility that favorable relationships with collaborators cannot
be established or, if established will be abandoned by the collaborators before
completion of product development; the possibility that the Company or its
collaborators will not successfully develop any products; the possibility that
advances by competitors will cause the Company's proposed products not to be
viable; uncertainties as to the requirement that a drug be found to be safe and
effective after extensive clinical trials and the possibility that the results
of such trials, if commenced and completed, will not establish the safety or the
efficacy of the Company's products; risks relating to requirements for approvals
by government agencies such as the FDA before products can be marketed and the
possibility that such approvals will not be obtained in a timely manner or at
all or will be conditioned in a manner that would impair the Company's ability
to market the product successfully; the risk that the Company's patents could be
invalidated or narrowed in scope by judicial actions or that the Company's
technology could infringe the patent or other intellectual property rights of
third parties; the possibility that the Company will not be able to raise
adequate capital to fund its operations through the process of developing and
testing a successful product or that future financing will be completed on
unfavourable terms; the possibility that any products successfully developed by
the Company will not achieve market acceptance; and other risks and
uncertainties which may not be described herein. Further information concerning
these and other risks and uncertainties is included under "Item 1 - Description
of Business - Risk Factors". These risks and uncertainties should be considered
when evaluating forward looking statements, and undue reliance should not be
placed upon forward looking statements.

The information in this Registration Statement is as at April 30, 2000 unless
otherwise stated.

The Company was formed by the amalgamation, under the Company Act (British
Columbia), of Immune Network and BCFC on April 24, 1996.

The Amalgamation was completed pursuant to an agreement (the "Amalgamation
Agreement") between Immune Network and BCFC following receipt of (i) required
securityholders approval, (ii) an order from the Supreme Court of British
Columbia approving the Amalgamation under section 237 of the Company Act
(British Columbia), and (iii) acceptance from the Vancouver Stock Exchange to
the filing of documentation relating to the Amalgamation.  The Amalgamation
became effective upon the issuance of a certificate of amalgamation by the
Registrar of Companies for the Province of British Columbia on April 24, 1996.

The principal features of the Amalgamation are summarized as follows:

   *  The property, assets and liabilities of each of Immune Network and BCFC
      became the property, assets and liabilities of the Company.

   *  The Company issued Shares to the shareholders of Immune Network and BCFC,
      as follows:

      (a) the issued and outstanding common shares of Immune Network were
          exchanged for 7,664,653  Shares, and 5,066,667 Shares in escrow, on
          the basis of 1.33 Shares for each one Immune Network common share
          held; and

      (b) the issued and outstanding common shares of BCFC were exchanged for
          4,263,309 Shares on the basis of two Shares for each three BCFC common
          shares held.

   *  The holders of options to acquire shares of BCFC were deemed to be holders
      of options to acquire that number of Shares (333,333 at the time of the
      Amalgamation) resulting from the application of a 3:2 share exchange ratio
      to the number of common shares of BCFC that such holder could previously
      acquire.

B.    Business of the Company
      -----------------------

The Company is a biotechnology company focused on the development of new drugs
to treat major diseases, predominantly involving the body's immune system.
Using both its internal expertise and external network, the Company's objective
is to accelerate the period in which a return on investment would typically be
recognized with traditional biotechnology companies through participation in
"special situations" in biotechnology.  The Company's current projects, listed
below, may all be considered special situations:

   *  AIDS project
   *  Alzheimer Disease project
   *  Asthma project

The Company's goal is to capitalize on special situations through a strategy of
acquisition of rights or other interest in the project, addition of value, and
rapid divestiture through licenses, alliances, or other disposition.  Special
situations in biotechnology are stalled projects that have an underlying
foundation of strong science, protectable intellectual property, and a clearly
indentified market niche.  A stalled project is a project initiated by another
party, the development of which has been suspended for any of a number of
reasons such as a lack of financial or management resources, for such period of
time that the value of the project may have been materially reduced.  The

<PAGE>

Company differentiates itself from other biotechnology companies by focusing on
the potential for rapid return on investment rather than focusing on a
particular scientific or therapeutic specialization.  The Company intends to
collaborate with development partners and contract research organizations on its
projects.

See "Item 1 - Description of Business - Projects".

During the five years preceding the date of this Registration Statement, the
general development of the Company and its predecessor, Immune Network,  has
been as follows:

   *  The Company was formed on April 24, 1996, the effective date of the
      Amalgamation.

   *  In December 1997, as amended in December 1998, the Company entered into
      a research agreement with Immpheron, Inc. regarding the AIDS project (see
      "Item 1 - Description of Business - Material Agreements - Immpheron,
      Inc.").

   *  On December 15, 1998, the Company was issued a U.S. patent for its
      "Anti-idiotypic antibody" and its use in diagnosis and therapy in HIV-
      related diseases (see "Item 1 - Description of Business - Patents").

   *  In July 1999, the Company entered into an agreement with the University
      of British Columbia (the "UBC Option Agreement") whereby the Company was
      granted an option to license dapsone, a drug currently in use for other
      conditions, for the treatment of Alzheimer disease (see "Item 1 -
      Description of Business - Material Agreements - University of British
      Columbia").

   *  In August 1999, the Company entered into a joint venture arrangement
      with Bridge Pharma, Inc. for the development of a new asthma therapeutic
      (see "Item 1 - Description of Business - Material Agreements - Bridge
      Pharma, Inc.").  The joint venture operations commenced in October 1999.

   *  In October 1999, the Company exercised its option to license dapsone
      from the University of British Columbia (see "Item 1 - Description of
      Business - Material Agreements - University of British Columbia").

   *  In December 1999, the Company entered into an agreement to reacquire the
      50% interest in the Antibody 1F7 previously acquired by ImmPheron, Inc.
      (see "Item 1 - Description of Business - Material Agreements - ImmPheron,
      Inc.")

   *  In February 2000, the Company acquired an option from Meditech
      Pharmaceuticals Inc. to acquire an exclusive license on two of Meditech
      Pharmaceutical Inc.'s drugs, Viraplex and MTCH-24 (see "Item 1 -
      Description of Business - Material Agreements - Meditech Pharmaceuticals
      Inc.").

   *  In March 2000, the Company and CroMedica Global, Inc., a contract research
      organization, entered into an agreement whereby CroMedica Global Inc.
      will provide services relating to the clinical trial program for the
      Company's patented drug candidate for Alzheimer disease (see "Item 1 -
      Description of Business - Material Agreements - CroMedica Global Inc.").

   *  In April 2000, the Company and Bridge Pharma, Inc. signed an addendum
      under which they agreed to add the use of certain compounds for the
      treatment of atopic dermatitis (eczema) (see "Item 1 - Description of
      Business - Material Agreements - Bridge Pharma, Inc.").

<PAGE>

The Company expects to complete the following milestones in Fiscal 2000: (1)
completion of the investigational new drug application for its AIDS project drug
candidate IQ199, in either Canada or the United States; (2) initiation of a
Phase I/II clinical trial of IQ199 and Phase II trial of its Alzheimer drug
candidate IQ200; and (3) initiation of in vitro and in vivo testing of the
Asthma project compound. See "Item 1 - Description of Business - Projects" and
"Item 1 - Description of Business  - Government Regulation".

The Company completed three private placements during the period from January 1,
1999 through to February 29, 2000,  raising $1,314,997, the stated use of
proceeds of which is as follows:

     $   318,000   -  research activities - pharmacology testing and preparation
                      for clinical trials
     $   100,000   -  test material production - synthesis of compounds and
                      compositions required for further testing and product
                      development
     $   150,000   -  preclinical development - toxicity testing and preparation
                      of data
     $   100,000   -  clinical regulatory expenses - consultation with
                      regulatory experts and preparation of regulatory filings
     $   392,977   -  general working capital
     $   254,020   -  general and administrative expenses

Subsequent to February 29, 2000, the Company completed a brokered private
placement with Groome Capital.com Inc. of 15,454,544 special warrants at $0.55
each, raising net proceeds of $7,791,911.23 after deduction of agent's
commission and expenses.  See "Options to Purchase Securities From the Company"
for details of the special warrants issued.  The net proceeds from this private
placement will be utilized as follows:

     $5,500,000    -  clinical trials (AIDS and Alzheimer projects)
     $1,600,000    -  research and development
     $  350,413    -  general and administrative
     $  341,498.20 -  general working capital

The Company is in the development stage and currently derives no revenues from
its operations.  The Company's ability to remain as a going concern is dependent
on additional capital being raised to fund future operations and on-going
research and development activities.  The Company believes that the funds
received from its most recent private placement will be sufficient to finance
the Company's operations for the remainder of the current fiscal year.  The
Financial Statements have been prepared assuming the Company will continue as a
going concern and reference should be made to Note 1(a) of the Financial
Statements.

The Company is dependent on generating income primarily by raising funds by the
issuance of shares in order to finance research and development activities and
meet general and administrative expenses in the medium term.  The Company plans
to collaborate with development partners on its AIDS and Alzheimer disease
projects, reducing the requirement for capital.  In the long term, the Company
intends to derive its income from licensing arrangements and divestitures of
intellectual property.  There can be no assurance that the Company will be
successful in raising the required financing or in carrying out intellectual
property transactions that produce income.  Reference should be made to "Item 1
- Business of the Company - Risk Factors" for disclosure of the distinctive or
special characteristics of the Company's operations or industry which may have a
material impact upon its future financial performance.

As at April 30, 2000, the Company had 9 full-time employees and 3 part-time
employees, 10 of whom are involved in research and development and 2 of whom are
engaged in administration.

The Company does not anticipate any material acquisition or any material
increase in the number of employees in the foreseeable future.

The Company has met all commitments to date and is not in arrears of its
financial obligations.

(1)  Preclinical includes pharmacological and efficacy testing in animals,
     toxicology testing and formulation work.  After completion of such actions,
     the product, with the approval of a governing body, can enter human trials
     (Phases I, II and III).  See "Item 1 - Description of Business - Government
     Regulation".
(2)  A Phase II clinical trial is a pivotal trial designed to test a drug's
     effectiveness in a relevant patient group.  The Company has contracted with
     experts to assess the data available to date and to determine an optimal
     clinical testing and commercialization strategy.

AIDS Project

The goal of the Company's AIDS project is to develop an AIDS therapy, IQ199, a
type of monoclonal antibody that addresses two major problems facing current
drugs: (1) the existence of various strains of HIV with different sensitivity to
existing therapies; and (2) the ability of HIV to mutate which allows the virus
to become resistant to existing drug therapy.

AIDS is caused by HIV1 and is generally transmitted between humans through the
transfer of bodily fluids. AIDS occurs because the HIV virus destroys the immune
system of infected individuals2. After initial infection, lymphatic B-cells of
the immune system begin producing antibodies specific to the infecting viral

strain3.  Antibodies are  proteins secreted by cells in the blood that help the
body fight infections and diseases by searching out and selectively binding to
their targets to guard the immune system against infectious microorganisms.
Monoclonal antibodies are an important part of developing therapies that work.
The term "monoclonal" refers to the fact that the cells which secrete the
antibodies are derived from clones, or identical copies, of a single cell.
Monoclonal antibodies are screened in the laboratory and selected for their
sensitivity and specificity to particular target receptors so that they can be
utilized to diagnose and/or treat specific diseases.

Viral replication is initially suppressed by the immune system; however, due to
a high viral mutation rate, new forms of the virus are produced.  The immune
system does not produce antibodies specific to the new variants but continues to
produce antibodies against the original strain4 - this is called the "clonotypic
effect".  The antibodies produced against the original viral strain are
ineffective against the new variants.  Unchecked by the body's immune system,
the new viral strains proliferate, leading to the destruction or functional
impairment of cells of the immune system and inhibition of the body's ability to
fight infections and certain cancers5.

Current therapy for HIV infection is often ineffective in the long term since
these agents usually target only specific strains of HIV.  When the virus
mutates, the drugs become ineffective.  Many drug companies have attempted to
overcome this problem by developing therapeutics that recognize more than one
strain of HIV (e.g. Glaxo Inc., Pfizer Inc.).  However, with continuous viral
mutation, the long-term effectiveness of these therapies is limited.
Previously, combinations of several anti-HIV drugs were shown to be effective in
patients with AIDS symptoms6.  Recently, however, as a result of the appearance
of new drug resistant HIV strains, trials using combination drug approaches have
been unsuccessful at reducing AIDS symptoms7.  In addition, serious drug side
effects and high medication costs make patient compliance difficult to maintain.
Therefore, current therapies may not provide a long-term solution to AIDS,
making alternative approaches in AIDS therapy increasingly desirable.

IQ199, the Company's 1F7 monoclonal antibody, is a novel approach for treating
HIV infection aimed at resetting the body's immune system to continue to fight
the AIDS virus even as the virus mutates.  1F7 was discovered in 1993 by Drs.
Sybille Muller, Heinz Kohler, Michael Grant and Haitao Wang and ispatent-
protected by the authors in the U.S. (see "Item 1 - Description of Business -
Patents").  IQ199 is an antibody produced in mice that appears to reset the
body's immune system, thereby facilitating its response against new strains of
HIV8.  IQ199 is not directed against HIV itself but is able to stimulate the
immune system directly.  IQ199 stimulates the immune system by suppressing the
"B-cells" that produce antibodies against the original HIV strain and also

stimulates other lines of "B-cells" to produce antibodies against the new mutant
virus strains8.

An experiment was carried out to test the efficacy of 1F7 in suppressing
dominant antibody responses in HIV-infected macaque monkeys8.  Significant
increases in the number of anti-HIV antibodies for more than one virus strains
(HIV-1 IIIB and MN) were detected in the blood of the 1F7-inoculated macaques.
Moreover, in all three injected monkeys, antibody binding to three different HIV
strains (MN, CM and SF2) that are not targeted by the 1F7 antibody increased
following 1F7 injection.  These results suggest that the monkey's immune system
became more effective against HIV strains after 1F7 injection.

In HIV patients the CD8+ "cytotoxic" cells of the immune system destroy its own
CD4+ "helper" T-cells that have become infected with the virus.  It appears that
a key factor in the pathology of AIDS is that cytotoxic T-cells also kill
uninfected helper T-cells9.  Early in vitro experiments conducted by Dr.
Michael Grant have demonstrated that 1F7 selectively inhibited the destruction
of uninfected CD4+ cells by the cytotoxic T-cells in HIV-infected
individuals10.

In summary, the experiments conducted by Dr. Muller and colleagues and Dr. Grant
suggest that the monoclonal antibody 1F7 has several important effects on both
humoral (antibody-mediated) and cellular immunity mechanisms  that make it an
ideal candidate for an HIV therapy.  In addition, the failure or limited success
of other drug therapies opens the market for new and novel AIDS therapeutics
such as 1F7.

The Company has licensed the antibody 1F7 technology from the San Diego Regional
Cancer Center (see "Description of Business - Material Agreements - Sidney
Kimmel Cancer Center") and has further patents pending regarding the antibody
1F7 (see "Description of Business - Patents - AIDS Project").

The AIDS project is in the preclinical stage.  The Company is currently
preparing an investigational new drug ("IND") application for filing with the
regulatory agencies upon completion of preclinical studies (see "Item 1 -
Description of Business - Government Regulation").  Once the IND becomes
effective, the Company can then begin the first of three phases of clinical
trials.  Preliminary discussions are being held with various research
organizations and the regulatory agencies regarding the requirements and
conditions for a clinical trial.

Alzheimers Disease Project

The short term goal of the Company's Alzheimer disease project is to
demonstrate that dapsone, a drug currently in use for other conditions, is
effective in slowing the progression of Alzheimer disease.  The Company has
developed a clinical, regulatory and commercial strategy for the project.
Clinical trials for IQ200, the first generation compound in this project, have
been designed to confirm the ability of the compound to slow the progression of
dementia in confirmed Alzheimer disease patients.  The Company is also
conducting research on IQ201 and subsequent candidates as possible second
generation agents for prevention of onset and/or slowing the progression of
Alzheimer disease.

Alzheimer disease is a condition characterized by death of brain cells and
severe degradation of mental health.  Primarily affecting the elderly, Alzheimer
disease currently afflicts over 35 million people worldwide11 and is the eighth
leading cause of death in people aged 65 and older in the United States12.
Presently, there are only two drugs approved for the treatment of this disease -
both treat the symptoms of the disease by temporarily improving brain function
but they do not arrest or slow the  progression of the disease.

In 1992, researchers at the University of British Columbia conducted a
retrospective study on the prevalence of dementia among elderly Japanese
patients receiving dapsone13. They found that the occurrence of dementia was 37%
lower in patients chronically treated with dapsone as compared to patients not
receiving dapsone.  These results suggest that continuous therapy with dapsone
(IQ200) may lower the incidence of dementia.

The Company entered into an option agreement with the University of British
Columbia (the "UBC Option Agreement") for an exclusive worldwide license on a
patent that covers the use of dapsone and related compounds for the treatment of
dementia, with rights to manufacture, distribute and sell products based on such
technology (see "Item 1 - Description of Business - Patents").  Subsequently the
Company exercised its option and is currently finalizing the terms of the
license agreement (see "Item 1 - Description of Business - Material Contracts -
UBC Option Agreement").

Based on a positive statistical analysis of data from the restrospective study,
the Company will be proceeding with a Phase II, multi-center clinical research
program for this drug candidate.  The Phase II research program will be
conducted by CroMedical Global Inc. ("CroMedica"), an arm's length clinical
research operating facility (see "Description of Business - Material Agreements
- CroMedica Global Inc.").  The three-country clinical trial program has been
designed by CroMedica to establish the efficacy of the Company's patented drug
candidate against the progression of Alzheimer disease.  The patient selection
process is scheduled to begin before the end of the current year, with first
results anticipated in year 2001.  CroMedica will be responsible for the
coordination, management and conduct of the studies.  Total expenses are
expected to be US$13 million over three years.  The Company will need to secure
additional funds, through financings and/or collaborative agreements, to cover
much of the cost associated with the completion of the Phase II clinical
research program.  There can be no assurance that such additional funds will be
secured at all or in a timely manner.

A project plan is currently being developed for a second pharmaceutical
composition for Alzheimer disease therapy (IQ201) which may be advanced into
clinical development as part of an arm's length agreement entered into between
the Company and CroMedica (see "Item 1 - Description of Business - Material
Agreements - CroMedica Global Inc.").  When this project is initiated, IQ201
will enter into the preclinical stage of development.  Initial expenses for this
project are expected to be nominal.

Asthma Project

The goal of the Company's asthma project is to synthesize and test several new
compounds that have, in laboratory studies, demonstrated possible disease-
modifying actions in asthma.  Pursuant to a research agreement between the
Company and Bridge Pharma, Inc. (see "Item 1 - Description of Business -
Material Agreements - Bridge Pharma, Inc."), the research will involve the

exploration of targeted mast cell stabilizers which are effective but may not
possess the side-effects associated with steroids and other drugs that are
currently available for the treatment of asthma.  Initial data from Bridge
Pharma, Inc. indicates that these novel, non-steroidal, disease-modifying
therapeutics have a better activity profile with fewer side effects than other
drugs of their class.  Bridge Pharma, Inc. intends to screen these compounds in
laboratory models of asthma, select a clinical candidate and initiate clinical
testing of this candidate drug.

Asthma is a disorder characterized by chronic inflammation and hyper-sensitivity
of the air passages in the lung.  People who suffer from asthma experience
"attacks" during which their air passages contract causing difficulty in
breathing.  Temporary relief from the symptoms of asthma is currently achieved
through use of bronchodilators that re-open the air passages.  Recently, a
better understanding of the underlying pathophysiology of asthma has led to the
conclusion that long-term management of asthma should be achieved with safe,
disease-modifying drugs, and to acutely maintain normal lung function with the
use of bronchodilator drugs only as needed.  Although various bronchodilator
drugs are currently available, there is still a need for effective,
well-tolerated, non-steroidal, disease-modifying drugs.

Asthma appears to involve the release of many inflammatory agents that are
involved in allergic reactions.  Inhibiting a single mediator is not always
effective.  Inhibition of multiple mediators is more likely to produce a
broad-based anti-inflammatory effect.  The only known method to meet such a goal
is to inhibit the release of inflammatory agents by stabilizing the cells that
produce them.

The patent application for the drug candidate under the Asthma project is part
of the intellectual property covered by the Company's agreement with Bridge
Pharma, Inc.  The Asthma project is in the preclinical stage.  Total expenses
related to this project are expected to be up to a maximum of $3 million over
two years.  The Company will need to secure additional funds, through sources
such as financings and/or collaborative agreements, to cover much of the costs
associated with the completion of research and development relating to the
Asthma project.  There can be no assurance that such additional funds will be
secured at all or in a timely manner.

D.   Material Agreements
     -------------------

Sidney Kimmel Cancer Center

By an arms length exclusive licensing agreement dated April 23, 1993 (the "1F7
License Agreement") entered into between the Company and the San Diego Regional
Cancer Center (now known as the Sidney Kimmel Cancer Center) (the "Cancer
Center"), the Company was granted an exclusive license to use and sublicense the
technology  characterized as "Antibody 1F7" (see "Item 1 - Description of
Business - Patents") and to make or have made licensed products in all countries
of the world in which the Cancer Center has patent rights, and to sell licensed
products worldwide.  Under the terms of the 1F7 License Agreement, the Company
is required to pay to the Cancer Center a royalty equal to 2% of net sales of
therapeutic licensed products and 5% of net sales of diagnostic licensed
products resulting from Antibody 1F7 technology.

The 1F7 License Agreement shall expire on the later of: (a) April 23, 2010; or
(b) expiry of the last remaining patent rights.  The Company may continue to
utilize the technology under the 1F7 License Agreement after the expiration of
the last remaining patent rights, but shall not have any further royalty or
other payment obligations to the Cancer Center.

Subject to its terms and conditions, the 1F7 License Agreement may be
terminated: (a) at any time by the Cancer Center if the Company files in any

court a bankruptcy or insolvency petition; (b) by either party upon failure of
the other party to remedy a breach for which notice was given; and (c) upon 60
days' written notice by the Company to the Cancer Center.

The Company has paid a license fee of US$10,000 to the Cancer Center.

ImmPheron, Inc.

By an arms length agreement dated December 15, 1997, as amended December 15,1998
(the "Immpheron Agreement"), the Company formed a strategic partnership with
Immpheron, Inc. ("Immpheron") to continue research and development of monoclonal
Antibody 1F7 and the intellectual property related to its use as a therapeutic
for the prevention and treatment of HIV infection. See "Item 1 - Description of
Business - AIDS Project (1F7)".  By incurring US$81,000 in preclinical trial
expenditures, Immpheron acquired a 50% interest in the Antibody 1F7 technology
licensed from the Cancer Center.

By letter agreement dated December 20, 1999 (the "Purchase Agreement"), the
Company reacquired the 50% interest in the Antibody 1F7 acquired by ImmPheron,
in consideration of the following payments and royalty grant to ImmPheron:

(a) US$4,000 on execution of the agreement (paid);

(b) US$2,000 on each of January 31, February 29, March 31 and April 30, 2000
    (all paid);

(c) US$88,000 on July 20, 2000;

(d) US$10,000 within 30 business days of the commencement of a Phase I clinical
    trial; and

(e) 4% royalty on net earnings from the Antibody 1F7.

University of British Columbia

Pursuant to an arms length agreement (the "UBC Option Agreement"), the Company
has exercised an option granted by the University of British Columbia ("UBC")
for the world-wide license to use and sublicense dapsone, a drug currently in
use for other conditions, for the treatment of Alzheimer disease, and the
manufacture, distribution and sale of products based on such technology (see
"Item 1 - Description of Business - Alzheimer Disease Project").  A formal
license agreement is currently being negotiated by the Company and UBC which is
to include the following material terms:

(a) an initial, non-refundable, license fee will be payable upon execution
    of the license agreement, which is intended to partially reimburse UBC for
    its costs of developing, protecting and licensing the technology;

(b) payments will be made to UBC upon certain milestones being reached,
    including the initiation of phase III clinical trials, filing of an NDA with
    the FDA, and upon receipt of FDA approval for marketing;

(c) a royalty will be paid to UBC based upon the total gross revenue derived
    from the sale of products using the technology;

(d) an annual, non-refundable, license maintenance fee of $1,000 will be paid
    in advance to UBC;

<PAGE>

(e) UBC will own and manage the patent portfolio, including all patents for
    improvements.  The Company will pay all future patent application, patent
    prosecution and patent maintenance costs and will reimburse all cost
    incurred to date by UBC and, in return, the Company will have the right to
    designate which technologies should be patented and shall become a licensee
    of all resulting patents on the same terms and provided in the license
    agreement;

(f) although UBC does not generally assign its technology, provision will be
    made for such assignment upon the achievement of certain milestones; and

(g) the license agreement will terminate with respect to any patent and
    royalties applicable thereto, on the expiration or official determination of
    invalidity of the patent, and with respect to the know-how and all other
    rights, on the later to occur of expiration or invalidity of the last
    patent, if any, licensed under the license agreement or the expiration of
    ten years from the date of the license agreement.

Bridge Pharma, Inc.

By an arms length agreement dated August 12, 1999 (the "Bridge Pharma
Agreement") with Bridge Pharma, Inc. ("BPI"), the Company has entered into a
joint venture arrangement, on a 50-50 basis, with BPI for the development of a
new asthma therapeutic.  In order to retain its 50% interest, the Company is
required to provide up to US$2 million in funding to the project over a period
of two years.  Any additional funding required above the first US$2 million will
be shared equally between the parties.  The goal of the collaboration between
the Company and BPI is to finish the work necessary to complete clinical trials
either as a continuance of the joint venture or in alliance with a strategic
partner.  See "Item 1 - Description of Business - Asthma Project".

Bridge Pharma, Inc. and the Company shall each own an undivided 50% interest in
all technology invented, discovered, acquired or developed under the joint
venture or with the use of the defined technology of the other party.

Pursuant to an addendum agreement dated April 4, 2000 (the "Bridge Pharma
Addendum"), the Company and Bridge Pharma, Inc. agreed to add to the joint
venture the use of certain additional compounds and the associated intellectual
property for the treatment of atopic dermatitis (eczema), subject to Canadian
Venture Exchange acceptance.  The Company has agreed that it will increase its
initial funding obligation from US$2 million to US$3.5 million if and when the
Company and Bridge Pharma, Inc. both agree on the selection of at least one of
the additional compounds to proceed to clinical trials.

Meditech Pharmaceuticals Inc.

By an arms length agreement dated February 3, 2000 (the "Meditech Agreement"),
Meditech Pharmaceuticals Inc. ("Meditech") has granted to the Company an
irrevocable one year option (the "Option") to acquire an exclusive, worldwide
(exclusive of the United States)  license on two of Meditech's drugs, Viraplex
and MTCH-24, or any derivatives or formulations thereof.  In consideration of
the grant of the Option, the Company paid the sum of US$25,000 and incurred the
required amount of US$20,000 in research and development expenditures relating
to these two drugs.

The Company has given written notice of the exercise of the Option and upon
execution of the license agreement will pay Meditech a license fee of
US$100,000.  The license agreement will provide for the payment to Meditech of a
royalty on net sales of 7% for MTCH-24 or any derivatives or formulations of
MTCH-24, and 4% for Viraplex or any derivatives or formulations of Viraplex.

CroMedica Global Inc.

Pursuant to an arm's length agreement entered into on March 27, 2000 (the
"CroMedica Agreement"), CroMedica Global Inc. ("CroMedica") has designed a
three-country clinical trial program to test the efficacy of the Company's
patented drug candidate against the progression of Alzheimer disease.  CroMedica
will be responsible for the coordination, management and conduct of the studies
(see "Item 1 - Description of Business - Projects - Alzheimer Disease Project").
The CroMedica Agreement is a fixed price contract, with the price being either
US$13,199,286 ("Option A Pricing") or US$13,849,286 ("Option B Pricing"),
exclusive of all applicable taxes, dependent upon whether the Company elects to
proceed with a second generation technology known as the IQ201 project.  As of
April 30, 2000, the Company has paid CroMedica $1,964,742 (net of GST) under the
CroMedica Agreement.  CroMedica has agreed to defer payment by the Company of
US$2,000,000 of the costs under the CroMedica Agreement.  The amount of the
payment deferral from time to time will be secured by a debenture issued by the
Company on March 27, 2000 in favour of CroMedica (the "CroMedica Debenture").
The CroMedica Debenture was accepted for filing by the Canadian Venture Exchange
on April 13, 2000.

The CroMedica Debenture will secure up to a maximum principal amount of
US$2,000,000 (approximately  Cdn$2,907,000).  As of April 30, 2000, the
principal amount secured under the CroMedica Debenture is US$1,000,000
(approximately Cdn$1,453,500).  The principal amount shall be increased by
either US$200,000 (approximately Cdn$290,700) on the first day of each month
from June through October 2001 if Option A Pricing applies, or by US$200,000 on
the first day of each month from October 2001 through February 2002 if Option B
Pricing applies.

The principal amount outstanding under the CroMedica Debenture will be paid in
equal monthly instalments (except for one month's payment which will double the
amount of the payment made the other months) on the first day of each month from
October 2001 through August 2003.  The CroMedica Debenture provides for interest
at the rate equal to the prime rate of interest charged by the Bank of Montreal
for Canadian loans to Canadian customers, plus 5%.  Interest shall be payable
commencing on October 1, 2001 and shall be calculated from the time of their
deferral under the CroMedica Agreement.

As security for the payment of all amounts payable under the CroMedica Debenture
and the performance by the Company of its obligations thereunder, the Company
has granted CroMedica a security interest in all of its present and future
property and assets.  Accordingly, if the Company is unable to repay the
indebtedness secured by the CroMedica Debenture, all of its property and assets,
including its intellectual property, shall be subject to seizure to the extent
of its indebtedness to CroMedica.

The Company may terminate the CroMedica Agreement upon 30 days' written notice
to CroMedica.  If such termination is the result of an external development
partnership, licensing agreement, corporate merger or acquisition, a termination
fee equal to 30% of the remaining payments under the CroMedica Agreement will be
due to CroMedica.  The termination fee will be 10% for termination of the
CroMedica Agreement by the Company for any other reason.

Donald Rix, a director of the Company, has disclosed his interest in this
transaction as a director of a subsidiary of CroMedica and, in accordance with
the provisions of the Company Act (British Columbia) abstained from voting on
approval of the CroMedica Agreement.

The CroMedica Agreement further provides that CroMedica is granted a right of
first refusal on all of the Company's clinical trials, other than the first
human trial, involving Antibody 1F7 (see "Item 1 - Description of Business -
Projects - AIDS Project").

The Company has the sole rights in any intellectual property arising from
research under the CroMedica Agreement.

E.   Markets
     -------

The pharmaceutical and related biotechnology industries are characterized by
extensive research efforts, rapid technology change and intense competition.
(See "Item 1 - Description of Business - Risk Factors".)  Competition in the
biopharmaceutical industry is based primarily on product performance, including
efficacy, safety, ease of use and adaptability to various modes of
administration, patient compliance, price, acceptance by physicians, marketing,
and distribution.  Barriers to entry into the market include the availability of
patent protection in the United States (the "U.S.") and other jurisdictions of
commercial interest, and the ability and time needed and cost to obtain
governmental approval for testing, manufacturing and marketing.

The Company's programs are in varying stages of development.  Products that may
result from the Company's research and development programs are not expected to
be commercially available for a number of years, if at all, and it will be a
number of years, if ever, before the Company will receive any significant
royalty revenues from commercial sales of such products.  Therefore, any
discussion of a market for the Company's products is of a very preliminary
nature.  In addition, some of the Company's competition may have substantially
more financial and technical resources, more extensive research and development
capabilities, products at a later stage of development, and greater marketing,
distribution, production and human resources than the Company.  (See "Item 1 -
Description of Business - Risk Factors").

The statistical information provided throughout this section has been sourced
from  the Company's market research reports, from public offering disclosure
published by competitors believed by the Company to be accurate, from published
data, and from the Company's experience in the industry.

AIDS Project

AIDS was first recognized in 1981 and has since become a major epidemic,
affecting more than 30 million people worldwide14.

The current U.S. market for HIV drugs is estimated to be in excess of US$3
billion15.  The Company feels that its 1F7 antibody, drug candidate IQ199, could
represent an important new treatment for HIV which would compete for a
significant portion of this market.

The monoclonal antibody IQ199 will compete primarily with other treatments that
improve the quality of life for HIV-infected individuals.  Current treatment
includes two classes of agents known as antiviral and immune stimulating agents.
There are several problems with the current therapeutics such as viral
resistance, serious health complications, and high treatment cost.  The
mechanism of action of IQ199 is different from current HIV drugs and may
represent a more effective approach, associated with a wider therapeutic window.
By blocking clonal dominance, an inherent immune response, IQ199 should allow
the immune system to regain its ability to respond to the endogenous virus.
This unique mechanism of action gives IQ199 a potential competitive advantage
over other drug therapies.

------------------------------

<PAGE>
Page 18

The Company has carried out a survey of the scientific and patent literature and
has not found, nor is the Company aware of, any existing or potential AIDS
therapies that have a similar mechanism of action as IQ199.  Since multiple HIV
drugs are  often used in combination chemotherapy regimens, it is unlikely that
IQ199 will directly compete with individual AIDS therapeutics.  It is more
likely that IQ199 may become part of such combination regimens.

Alzheimer Disease Project

Competition currently exists among companies and research groups attempting to
develop new drugs to combat Alzheimer disease.  There are numerous drugs in
various stages of clinical trials.  These experimental drugs fall into one of
five categories: cholinominetics, antioxidants, estrogen replacement,
anti-inflammatories and others.  The FDA, however, has approved only two drugs.
(See "Item 1 - Description of Business - Government Regulation")  Both drugs are
acetylcholinesterase inhibitors, and their overall benefit to Alzheimer patients
is minimal.  The first such drug approved, tacrine, had side effects that
prevented it from being accepted in the market.  The most recently approved
agent, donepezil, produces only mild increases in alertness.  Despite this, most
physicians treating Alzheimer disease patients are expected to prescribe
donepezil because there are so few alternatives16.

NSAIDS (non-steroidal anti-inflammatory drugs) have shown some promise for use
in Alzheimer treatment, but the potential for serious gastrointestinal side
effects complicate their therapeutic use.  The new anti-inflammatory "COX-2
inhibitors" may be direct competitors with the Company's drug candidates.  The
competitors in this area are Merck and Co. Inc. and Searle and Co. Inc. which
are both conducting phase III clinical trials with their COX-2 inhibitors.
Other potential competitors include Aventis Pharma Inc. which is conducting
phase III clinical trials for its phosphodiesterase inhibitor, propentofylline,
and Neotherapeutics Inc. which is in phase II trials for its drug Neotrofin, a
nerve growth factor.

The Company's Alzheimer disease drug candidates have a unique combination of
actions with a manageable and well-established toxicology profile17.  The
Company's Alzheimer disease project represents a novel approach to
pharmacological therapy of Alzheimer disease by treating brain inflammation
which occurs during the illness18.  The Company's review of patent literature
further suggests that the Company's approach to treatment of this illness is
unique.

Despite their limited effectiveness and serious side-effects, the few drugs that
are approved for use in Alzheimer disease have U.S. sales that exceed US$400
million annually19.

Asthma Project

Asthma morbidity and mortality are increasing worldwide.  More than 12 million
Americans, including 5 million children, suffer from asthma.  Among adults in
the U.S., 1 in 20 is asthmatic and among children the prevalence is higher -
about 1 in 10 20 Allergy Clin Immun. 100, 771..  Asthma related mortality in the

U.S. and Canada has increased by more than 25% during the last 20 years, with
the direct annual cost estimated at over $7 billion annually in the U.S.
alone21.

Anti-asthmatic drugs for clinical use fall into two categories: (1) those which
primarily provide symptomatic relief (bronchodilators); and (2) those which
provide a long-term disease-modifying action22.  There is now a sound medical
rationale for the use of disease modifying agents as first-line drugs in the
management of chronic asthma.  Current asthma therapy is inadequate and
management believes that the future market for disease-modifying drugs, such as
IQ210 which is currently under development by Bridge Pharma, Inc. and the
Company, will be at least as large as the current market for symptomatic
bronchodilating drugs.

In the asthma therapeutic market, the Company's proposed asthma treatment will
compete primarily with other disease-modifying asthma therapies.  Current
treatment includes inhaled steroids, antiallergenic agents such as sodium
cromoglycate (inhalant) and ketotifen fumarate (systemic).  The anti-asthmatic
agent under research by the Company and its partner (see "Item 1 - Description
of Business - Material Agreements - Bridge Pharma, Inc.") has demonstrated in
Preclinical studies a better activity profile with fewer side effects than other
drugs of its class.  It is expected that this agent could become an important
treatment for asthma.

Several companies are working on new approaches to the treatment of asthma.
Potential competitors include Novartis Inc. and Genentech Inc. which are
developing a monoclonal antibody to bind IgE, a major component of allergy
induced asthma attacks.  Other potential competitors are Texas Biotechnology
Corporation, which is developing a selectin inhibitor that is currently in phase
II human trials; Inflazyme Pharmaceuticals Ltd., which has recently completed
phase I trials with a novel steroid analogue; Leukosite Inc., which has
completed phase I trials of a new compound to inhibit the production of
leukotrienes; and AVANIR Pharmaceuticals, Inc., which is in preclinical testing
of a compound to downregulate the production of IgE.  These competitors,
however, face many of the same difficulties as the Company in eventually
bringing their drugs to market.

Business Strategy

The Company's objective is to accelerate the period in which a return on
investment would typically be recognized with traditional biotechnology
companies through participation in "special situations" in biotechnology.  The
Company's current project may all be considered to be special situations.

Special situations in biotechnology are stalled projects that have an underlying
foundation of strong science, protectable intellectual property, and a clearly
identifiable market niche.  A stalled project is a project initiated by another
party, the development of which has been suspended for any number of reasons
such as a lack of financial or management resources, for such period of time
that the value of the project may have been materially reduced.  The Company's
goal is to capitalize on special situations through a strategy of acquisition of
rights or other interest in the project, addition of value, and rapid
divestiture through licenses, alliances, or other disposition.  The stage at
which such divestiture may occur is dependent upon the individual milestones for
each project.  The Company differentiates itself from other biotechnology
companies by focusing on the potential for rapid return on investments, rather
than focusing on a particular scientific or therapeutic specialization.

<PAGE>
Page 20

The Company conducts some of its own research and development but primarily
contracts out and seeks collaborative partners with experience in the
development and marketing of drugs in the relevant therapeutic areas.  Potential
partners must possess both the human and financial resources to spearhead the
clinical development of the Company's products as required by the FDA, the HPB,
and drug regulatory agencies in other countries.  The form of collaboration
depends, in part, on the product candidate, the stage of development, and the
partner's expertise.  The Company also expects any potential partner to market
the products.  No assurance can be given that any such proposed partnership
arrangements will be entered into, or, if entered into, will be successful in
completing the development programs for the drug candidate in any particular
jurisdiction.  (See "Item 1 - Description of Business - Risk Factors".)

The rationale behind the Company's business strategy is to avoid the large
expenses incurred in the later stages of clinical development, to obtain early
returns in the form of upfront fees and milestone payments, to utilize expertise
and resources of major multinational pharmaceutical companies, and to obtain
long term revenue streams through royalty payments on product sales.

Notwithstanding the Company's business strategy described above, the Company has
no regular cash flow  and is dependent on generating required funds primarily by
way of equity financing.  The Company expects to continue to rely on outside
sources of financing to meet its capital requirements for at least the next two
years.  There can be no assurance that the Company will be able to arrange and
complete the required financings on favourable terms.  Such equity financings
could be highly dilutive.  (See  Item 1 - Description of Business - Risk
Factors".)

The Company presently has no plans for developing an in-house marketing or
manufacturing capability.

F.   Research and Development Expenses
     ---------------------------------

During Fiscal 1998, 1997 and 1996, the Company spent $31,055, $77,548 and
$348,734, respectively, on research and development.

G.   Proprietary Protection
     ----------------------

General

The Company's patent strategy is to pursue, in selected jurisdictions, the
broadest possible patent protection on its proprietary products and technology.
The Company plans to protect its technology, inventions and improvements to
inventions by filing patent applications according to industry standards in a
timely fashion.

In addition to its patents, the Company also relies upon trade secrets, know-how
and the continuing technological innovations to develop its competitive
position.  It is the Company's policy to require its directors, employees,
consultants, members of its scientific advisory board and parties to
collaborative agreements to execute confidentiality agreements upon the
commencement of employment, consulting or collaborative relationships with the
Company.  These agreements provide that all confidential information developed
or made known during the course of the relationship with the Company is to be
kept confidential except in specific circumstances.  In the case of employees
and consultants, the agreements provide that all inventions resulting from work
performed for the Company utilizing property of the Company or relating to the
Company's business and conceived or completed by the individual during
employment are the exclusive property of the Company to the extent permitted by
law.

The Company, and licensors who have granted the Company rights to their
respective technologies (see "Item 1 - Description of Business - Projects"),
have been granted patents or have filed patent applications in the United States
and other jurisdictions (such as Canada, Japan, Germany, France, Italy and the
United Kingdom) in respect of certain core technologies utilized by the Company.
Given that the patent applications for these technologies involve complex legal,
scientific and factual questions, there can be no assurance that patent
applications relating to the technology used by the Company will result in
patents being issued or that, if issued, the patents will provide a competitive
advantage or will afford protection against competitors with similar technology,
or will not be challenged successfully or circumvented by competitors.

The following patents granted or filed have either been assigned to the Company
or licensed for use by the Company.

The Patent Cooperation Treaty ("PCT") is a multilateral treaty that was
concluded in Washington in 1970 and entered into force in 1978.  It is
administered by the International Bureau of the World Intellectual Property
Organization ("WIPO"), headquartered in Geneva, Switzerland.  The PCT
facilitates the obtaining of protection for inventions where such protection is
sought in any or all of the PCT contracting states (total of 104 at July 1999).
It provides for the filing of one patent application (the "international
application"), with effect in several contracting states, instead of filing
several separate national and/or regional patent applications.  At the present
time, an international application may include designations for regional patents
in respect of contracting states party to any of the following regional patent
treaties: The Protocol on Patents and Industrial Designs within the framework of
the African Regional Industrial Property Organization, the Eurasian Patent
Convention, the European Patent Convention, and the Agreement Establishing the
African Intellectual Property Organization.  The PCT does not eliminate the
necessity of prosecuting the international  application in the national phase of
processing before the national or regional offices, but it does facilitate such
prosecution in several important respects by virtue of the procedures carried
out first on all international applications during the international phase of
processing under the PCT.  The formalities check, the international search and
(optionally) the international preliminary examination carried out during the
international phase, as well as the automatic deferral of national processing
which is entailed, give the applicant more time and a better basis for deciding
whether and in what countries to further pursue the application.  Further
information may be obtained from the official WIPO internet website
(http://www.wipo.int).

H.   Government Regulation
     ---------------------

The research and development, manufacture and market of pharmaceutical products
are subject to regulation  by the Food and Drug Administration (the "FDA") in
the United States, by the Health Protection Branch (the "HPB") of the Department
of Health and Welfare Canada in Canada, and by comparable regulatory authorities
in other countries.  These national agencies and other federal, state,
provincial and local entities regulate the testing, manufacture, safety and
promotion of the Company's products.

Drug licensing laws require approval of manufacturing facilities, carefully
controlled research and testing of products, governmental review and approval of
results prior to marketing of therapeutic products, and adherence to Good
Manufacturing Practices during production.  Compliance with Good Manufacturing
Practices requires considerable time and resources in the area of production and
quality control.  Product approvals may be withdrawn if compliance with
regulatory standards is not maintained or if new evidence demonstrates that the
drug is unsafe or lacks efficacy for its intended use(s) becomes known after the
product reaches the market.

United States Regulation

The Company is required by the FDA to comply with the following procedures prior
to marketing its products:

   *  preclinical laboratory and animal toxicology tests;
   *  submission of an investigational new drug application ("IND"), which
      must become effective before human clinical trials commence;
   *  adequate and well-controlled human clinical trials to establish the
      safety and efficiacy of the drug for its intended application;
   *  the submission of a new drug application ("NDA") to the FDA; and
   *  FDA approval of a NDA prior to any commercial sale or shipment of the
      product, including pre-approval and post-approval inspections of
      manufacturing facilities.

Preclinical laboratory and animal toxicology tests must be performed to assess
the safety and potential efficacy of the product.  The results of these
preclinical tests are then submitted to the FDA as part of an IND requesting
authorization to initial human clinical trials.  Clinical trials may be
initiated only upon approval of the IND by the FDA.

Clinical trials involve the administration of the pharmaceutical product to
individuals under the supervision of qualified medical investigators.  Clinical
studies are conducted in accordance with protocols that detail the objectives of
a study, the parameters to be used to monitor safety and the efficacy criteria
to be evaluated.  Each protocol is submitted to the FDA prior to the
commencement of each clinical trial.  Clinical studies are typically conducted
in three sequential stages, which may overlap:

<PAGE>
Page 24


   Phase I:   Initial introduction of the compound into human subjects to
              test for safety, dosage, tolerance, metabolic interaction,
              distribution, excretion and pharmacodynamics.

   Phase II:  Studies in a limited patient population to:
               *   determine the efficacy of the product for specific,
                   targeted indications;
               *   determine optimal dosage; and
               *   identify possible adverse effects and safety risks.

In the event Phase II evaluations demonstrate that the drug is effective and has
an acceptable safety profile, Phase III of the clinical trial will proceed.

   Phase III: Clinical trials are undertaken to further evaluate clinical
              efficacy of the product and to further test for its safety within
              an expanded patient population at geographically dispersed
              clinical study sites.

Two key factors influencing the rate of progression of clinical trials are the
rates at which patients are available to participate in the research programs
and whether the effective treatments are currently available for the disease the
drug is intended to treat.

The Company or the FDA may suspend clinical trials at any time if either
believes the clinical subjects are being exposed to unacceptable health risks.
The results of the product development, analytical laboratory studies and
clinical studies are submitted to the FDA as part of an NDA for approval of the
marketing and commercialization of the controlled release product.

If the approval being sought is for a new therapeutic area on a previously
clinically tested drug the approval process will require a new full clinical
trial regime, from preclinical to Phase III.  However, if the approval being
sought is for a new indication within a therapeutic area on a drug that has been
through one or more stages of clinical trials, then it is possible, if the
indication is close enough to that of the original submission, that any clinical
data available on this drug might be used to avoid repetition of these trials.

The FDA may deny approval of an NDA if applicable regulatory criteria are not
satisfied or may require additional testing.  Product approvals may be withdrawn
if compliance within regulatory standards is not maintained or if problems occur
after the product reaches the market.  The FDA may require further testing and
surveillance programs to monitor the pharmaceutical product that has been
commercialized.  Noncompliance with applicable requirements can result in fines
and other judicially imposed sanctions, including product seizures, injunction
actions and criminal prosecutions.

Canadian Regulation

The regulations concerning the sale of pharmaceutical products in Canada are
substantially similar to those of the United States described above.

The Company must submit an IND to the HPB prior to conducting clinical trials of
a new drug in Canada.  This application includes information about the methods
of manufacture of the drug and controls, and preclinical laboratory and animal
toxicology tests on the safety and potential efficacy of the drug.  If the HPB
does not notify the Company within 60 days of receiving the application that the
application is unsatisfactory, the Company may proceed with clinical trials of

<PAGE>
Page 25

the drug.  The phases of clinical trials are the same as those described under
"United States Regulation" above.

The Company must submit a new drug submission ("NDS") to the HPB and receive a
notice of compliance from the HPB before selling a new drug in Canada.  The NDS
includes information describing the new drug, including its proper name, the
proposed name under which the new drug will be sold, a quantitative list of
ingredients of the new drug, the methods of manufacturing, processing and
packaging of the new drug, the controls applicable to these operations, the
tests conducted to establish the safety of the new drug, the results of clinical
trials and the effectiveness of the new drug when used as intended.  If the HPB
determines that the NDS meets the requirements of Canada's Food and Drugs Act
and Regulations, the HPB will issue a notice of compliance for the new drug.

The HPB may deny approval of an NDS if applicable regulatory criteria are not
satisfied, or the HPB may require additional testing of a product.  Product
approvals may be withdrawn if compliance with regulatory standards is not
maintained or if problems occur after the product reaches the market.  The HPB
may require further testing and surveillance programs to monitor the
pharmaceutical product which has been commercialized.  Noncompliance with
applicable requirements can result in fines and other judicially imposed
sanctions, including product seizures and criminal prosecutions.

Additional Regulatory Considerations

In addition to the regulatory approval process, the Company is also subject to
regulations under provincial, state and federal law, including requirements
regarding occupational safety, laboratory practices, environmental protection
and hazardous substance control.  Also, the Company may be subject to other
present and future local, provincial, state, federal and foreign regulations,
including possible future regulations of the biotechnology industry.

Certain provincial regulatory authorities in Canada have the ability to
determine whether the cost of a drug sold within its province will be reimbursed
by a provincial government health plan by listing drugs on formularies.  These
provincial formularies may affect the prices and/or volume of drugs sold within
such provinces.

Proposals have recently been made that, if implemented, would significantly
change Canada's drug approval system.  Basically, the recommendations emphasize
the need for efficiency in Canadian drug review.  Proposals include the
establishment of a separate agency for drug regulation with a revised approval
system based on those found in European Community countries.   However, there is
no assurance that such changes will be implemented or will expedite the approval
of new drug products.

The Canadian government has regulations which prohibit the issuance of a notice
of compliance for a medicine, other than the first medicine marketed in Canada,
provided that the patent owner of the medicine has filed a list of its Canadian
patents covering that medicine with the HPB.  After receiving such list, the HPB
may refuse to issue a notice of compliance permitting the importation or sale of
a patented medicine  to persons other than a patent owner until patents on the
medicine expire or are declared invalid by a court of competent jurisdiction.

PAGE 26

Regulation in Other Jurisdictions

The Company may decide to develop one or more of its compounds first in regions
outside of North America  and Europe, depending upon clinical and commercial
factors.  Currently, the Company has no plans in place for drug development
activities outside of these regions.

In addition to meeting the specific requirements of the country for which a drug
is first intended to be commercialized, the Company intends to meet and exceed
the North American regulatory guidelines for any of its drug development
programs that are not initially commenced in North America.

I.   Risk Factors
     ------------

The following provides a brief description of some of the risk factors which
should be considered in relation to the Company's business.  It must be
recognized that there are three primary markets for pharmaceuticals:  North
America, Europe and Japan/Asia, and the risk factors associated with the
Company's projects may vary according to the particular market being addressed.
Specific risk factors to be considered include, but are not limited to, those
listed below:

Early Stage of Development

All of the Company's products are in the research and/or development stage.  At
present, the Company does not own or possess rights to a marketable product
except for MTCH-24 (see "Item 1 - Description of Business - Material Agreements
- Meditech Pharmaceuticals Inc.").  There can be no assurance that any such
products will be fully developed and tested, and if fully developed and tested,
will perform in accordance with the Company's expectations.  There is also no
assurance that necessary regulatory approvals or clearances will be obtained in
a timely manner, if at all, or that any of the Company's products can be
successfully and profitably developed, produced and marketed, including MTCH-24.
The research may fail or the compounds may not meet regulatory approval for
human use.  Even if the Company's research programs are successful, development
of a marketable product will likely take several years.

There is no guarantee that the Company will make a satisfactory deal with a
major pharmaceutical company to conduct human clinical trials, to complete
product development, to obtain regulatory approval, or ultimately to market the
product.

Limited Revenues, History of Operating Loss and Accumulated Deficit

The Company has had no sales revenue to date.  Although the Company has been
involved with pharmaceuticals since 1991, it has been engaged only in research
and development.  The Company has incurred significant operating losses,
including net losses of $201,671 in Fiscal 1998, $262,744 in Fiscal 1997,
$825,674 in Fiscal 1996, $559,444 in Fiscal 1995, and $493,178 in Fiscal 1994.
At September 30, 1999, the Company had an accumulated deficit of $2,993,203.
Notwithstanding the Company's objective to accelerate the period in which a
return on investment would typically be recognized with traditional
biotechnology companies, for some projects it may be a number of years, if ever,
before the Company will receive any significant revenues from commercial sales
of products.  The future growth and profitability of the Company will be
principally dependent upon its ability to successfully complete development of,
obtain regulatory approvals for, and market or license its proposed products.
Accordingly, the Company's prospects must be considered in light of the risks,
expenses and difficulties frequently encountered in connection with the
establishment of a new business in a highly competitive industry, characterized
by new product introductions.  The Company anticipates that it will incur

<PAGE>
Page 27

substantial operating expenses in connection with the research, development,
testing and approval of its proposed products and expects these expenses to
result in continuing and significant losses until such time as the Company is
able to achieve adequate revenue levels.  There can be no assurance that the
Company will be able to significantly increase revenues or achieve profitable
operations.  Failure to obtain additional capital, if needed, would have a
material adverse effect on the Company's operations.  See "Item 9 - Management's
Discussion and Analysis of Financial Condition and Results of Operations".

Uncertainties of Additional Funding Required

The Company has sufficient funds to undertake its currently planned research and
development activities through Fiscal 2000.  However, the Company will require
substantial funds in order to conduct its future activities.  The Company
intends to seek these funds through equity financing, collaborative arrangements
with corporate sponsors, or from other sources.  The Company may also require
additional funds in order to acquire technology or products that complement the
Company's efforts.  There can be no assurance that additional financing will be
available on acceptable terms, if at all.  Additional equity financings could
result in significant dilution to existing shareholders.  If sufficient capital
is not available, or is available but at a prohibitive cost, the Company may be
required to delay, reduce the scope of, eliminate or divest one or more of its
discovery, research or development programs, any of which could have a material
adverse effect on the Company's business, financial condition and results of
operations.  See "Item 9 - Management's Discussion and Analysis of Financial
Condition and Results of Operations".

Security Interest Granted Over Property and Assets

The Company has issued the CroMedica Debenture to secure the repayment of the
principal amount of up to US$2,000,000 (approximately Cdn$2,907,000), of which
the principal amount of US$1,000,000 (approximately Cdn$1,453,500) is owing as
at April 30, 2000 (see "Item 1 - Description of Business - Material Agreements -
CroMedica Global Inc.").  Repayment of this principal amount in instalments
commencing October 1, 2001 is secured by a security interest in all of its
property and assets, including the Company's intellectual property.

Agreements with Other Parties

The Company may, in the future, be unable to meet its share of costs incurred
under agreements to which it is a party and the Company may have its interests
in certain licenses, rights or products subject to such agreements reduced as a
result.  Furthermore, if other parties to such agreements do not meet their
share of such costs, the Company may be unable to finance the costs required to
complete the recommended programs.

Patents, Permits and Licenses

The Company considers patent protection and proprietary technology to be
materially significant to its business.  The Company relies on certain patents
and pending applications relating to various aspects of its potential products
and technology.  These patents and patent applications are either owned by or
exclusively licensed to the Company.  There can be no assurance that the Company
will be able to obtain and retain all necessary patents, licenses and permits
that may be required to carry out the research and development, manufacturing,
preclinical and clinical testing, obtaining regulatory approvals and marketing
of commercial products.  There can also be no assurance that others will not
independently develop similar technologies, duplicate any technology developed
by the Company, the Company's technology will not infringe upon patents or other
rights owned by others, that any of the Company's patents will not be
challenged, invalidated or circumvented, or that the rights granted thereunder


<PAGE>
Page 28

will provide competitive advantages to the Company.  Litigation, which could
result in substantial cost to the Company, may be necessary to enforce the
Company's rights provided by its patents or to determine the scope and validity
of others' proprietary rights.

There have been no patent infringement claims filed by or against the Company.

No Assurance of Protection of Proprietary Information

Certain of the Company's know-how and proprietary technology may not be
patentable.  To protect its rights, the Company requires management personnel,
employees, consultants, advisors and collaborators to enter into confidentiality
agreements.  There is no assurance, however, that these agreements will provide
meaningful protection for the Company's trade secrets, know-how or other
proprietary information in the event of any unauthorized use or disclosure.

No Assurance Regarding Licensing of Proprietary Technology Owned by Others

The manufacture and sale of any products developed by the Company will involve
the use of processes, products, or information, the rights to certain of which
are owned by others.  Although the Company has obtained licenses or rights with
regard to the use of certain of such processes, products, and information, there
can be no assurance that such licenses or rights will not be terminated or
expire during critical periods, that the Company will be able to obtain licenses
or other rights which may be important to it, or, if obtained, that such
licenses will be obtained on favourable terms.  Some of these licenses provide
for limited periods of exclusivity that may be extended only with the consent of
the licensor.  There can be no assurance that extensions will be granted on any
or all such licenses.  This same restriction may be contained in licenses
obtained in the future.

No Assurance of Regulatory Approval - Potential Delays

The preclinical testing and clinical trials of any products developed by the
Company or its collaborators and the manufacturing, labeling, sale,
distribution, export or import, marketing, advertising and promotion of any new
products resulting therefrom are subject to regulation by federal, state and
local governmental authorities in the United States, principally the FDA, and by
other similar agencies in other countries (see "Item 1 - Description of Business
- Government Regulation").  In order for a product developed by the Company or
its collaborators to be marketed and sold in a particular country, it must
receive all relevant regulatory approvals or clearances.  The regulatory
process, which includes extensive preclinical studies and clinical trials of
each product in order to establish its safety and efficacy, is uncertain, can
take many years and requires the expenditures of substantial resources.  Data
obtained from a preclinical trial and clinical activities are susceptible to
varying interpretations which could delay, limit or prevent regulatory approval
or clearance.  In addition, delays or rejections may be encountered based upon
changes in regulatory policy during the period of product development and/or the
period of review of any application for regulatory approval or clearance for a
product.  Delays in obtaining regulatory approvals or clearances would adversely
affect the marketing of any products developed by the Company or its
collaborators, impose significant additional costs on the Company and its
collaborators, diminish any competitive advantages that the Company or its
collaborators may attain and adversely affect the Company's ability to receive
royalties and generate revenues and profits.  There can be no assurance that,
even after such time and expenditures, any required regulatory approvals or
clearances will be obtained for any products developed by or in collaboration
with the Company.

<PAGE>
Page 29

Any regulatory approval or clearances granted may entail limitations on the
indicated uses for which the new product may be marketed that could limit the
potential market for such product.  In addition, product approvals or
clearances, once granted, may be withdrawn if problems occur after initial
marketing.  Furthermore, manufacturers of approved products are subject to
pervasive review, including compliance with detailed regulation governing GMP
("Good Manufacturing Procedures").  Failure to comply with applicable regulatory
requirements can result in actions such as warning letters, fines, injunctions,
civil penalties, recall  or seizure of products, total or partial suspension of
production and refusal of the government to renew marketing applications or
criminal prosecution.

The Company is also subject to numerous federal, state and local laws,
regulations and recommendations relating to safe working conditions, laboratory
and manufacturing practices, the experimental use of animals, the environment
and the use and disposal of hazardous substances, used in connection with the
Company's discovery, research and development activities.  The Company is unable
to predict the extent of government regulations which might have an adverse
effect on the discovery, development, production and marketing of the Company's
products.  Also, there can be no assurance that the Company will not be required
to incur significant costs to comply with current or future laws or regulations
or that the Company will not be adversely affected by the cost of such
compliance.

No Assurance of Successful Manufacturing

The Company has no experience manufacturing commercial quantities of products
and does not currently have the resources to manufacture any products that it
may develop.  The Company presently has no plans for developing an in-house
marketing or manufacturing capability.  Accordingly, the Company will be
dependent upon securing a contract manufacturer or other third party to
manufacture such products.  There can be no assurance that the terms of any such
arrangement would be favorable enough to permit the products to compete
effectively in the marketplace.  There are presently no such arrangements in
place.

Delays from Non-Compliance with Good Manufacturing Practices ("GMP")

The manufacture of the Company's pharmaceutical products will be subject to
current GMP or similar regulations prescribed by the FDA in the United States,
the HPB in Canada and similar authorities prior to the commercial manufacture of
any such products in the countries where the products are manufactured.  There
can be no assurance that the Company or any entity manufacturing products on
behalf oft he Company will be able to comply with GMP or satisfy certain
regulatory inspections in connection with the manufacture of the Company's
proposed products.  Failure or delay by any manufacturer of the Company's
products to comply with GMP or similar regulations or satisfy regulatory
inspections would have a material adverse effect on the Company.

Competition

The biotechnology industry is intensely competitive.  Many companies, as well as
research organizations, currently engage in or have in the past engaged in
efforts related to the development of products in the same therapeutic areas as
the Company.  Many of the competing companies have significantly greater
financial resources and expertise than the Company.  Other smaller companies may
also prove to be significant competitors, particularly through collaborative
arrangements with large and established companies.  Academic institutions,
government agencies and other public and private research organizations may also
conduct research, seek patent protection and establish collaborative
arrangements for discovery, research, clinical development and marketing of
products similar to those of the Company.  There can be no assurance that
competitors will not develop more effective or more affordable products, or

<PAGE>
Page 30

achieve earlier patent protection or product commercialization than the Company
and its collaborators, or that such competitive products will not render the
Company's products obsolete.

With respect to the Company's Alzheimer disease project, Merck and Co. Inc. and
Searle & Co. Inc. may be direct competitors with the Company's drug candidates.
Other potential competitors include Aventis Pharma Inc. and Neotherapeutics Inc.
With respect to the Company's asthma project, potential competitors include
Novartis Inc., Genentech Inc., Texas Biotechnology Corporation, Inflazyme
Pharmaceuticals Inc., Leukosite Inc, and AVANIR Pharmaceuticals Inc.  With
respect to the Company's AIDS project, it is unlikely that the Company's drug
candidate will directly compete with individual AIDS therapies; the Company's
drug candidate would likely be part of a combination regimen.

No Assurance of Market Acceptance

There can be no assurance that any products successfully developed by the
Company or its corporate collaborators, if approved for marketing, will ever
achieve market acceptance.  The Company's products, if successfully developed,
may compete with a number of traditional drugs and therapies manufactured and
marketed by major pharmaceutical and biotechnology companies, as well as new
products currently under development by such companies and others.  The degree
of market acceptance of any products developed by the Company or its corporate
collaborators will depend on a number of factors, including the establishment
and demonstration of the clinical efficacy and safety of the product candidates,
their potential advantage over alternative treatment methods and reimbursement
of policies of government and third party payors.  There can be no assurance
that physicians, patients or the medical community in general will accept and
utilize any products that may be developed by the Company or its corporate
collaborators.

Dependence on and Management of Future Corporate Collaborations

The success of the Company's business strategy is largely dependent on its
ability to enter into collaborations and to effectively manage the relationships
that may come to exist as a result of this strategy. The Company is currently
seeking corporate collaborators, but there can be no assurance that such efforts
will lead to the establishment of any favourable collaboration.  There can be
no assurance that any of the Company's future or existing collaborators will
commit sufficient resources to the company's research and development programs
or the commercialization of its products. Also, there can be no assurance that
such collaborators will not pursue existing or other development-stage products
or alternative technologies in preference tothose being developed in
collaboration with the Company, or that disputes will not arise with respect to
ownership of technology developed under any such collaborations. Management of
the Company's collaborative relationships will require significant time and
effort from the Company's management team and effective allocation of the
Company's resources.

Management of Growth

The Company's future growth, if any, may cause a significant strain on its
management, operational, financial and other resources. The Company's ability
to manage its growth effectively will require it to implement and improve its
operational, financial, manufacturing and management information systems and to
expand, train, manage and motivate its employees. These demands may require the
addition of new management personnel and the development of additional expertise
by management. Any increase in resources devoted to research, product
development and marketing and sales efforts without a corresponding increase in
the Company's operational, financial, manufacturing and management information
systems could have a material adverse effect on the Company's business,
financial condition, and results of operations.

<PAGE>
Page 31

Dependence Upon Key Personnel

The Company is dependent upon all members of its management team and the loss of
any of these employees could have an adverse effect on the Company to the extent
the Company is unable to hire a replacement in a timely manner. However, the
Company has implemented a continuous training program to expose its employees to
areas outside of their direct responsibility so as to minimize the disruption
encountered by the loss of any employee.  Competition among biotechnology and
biotechnology companies for qualified employees is intense, and the ability to
retain and attract qualified individuals is critical to the success of the
Company. In order to reduce its risk regarding key employees, the Company has
entered into an employment agreement with each of its key employees. The
Company is also dependent, to some extent, on the guidance of certain members of
its scientific advisory board, none of whom is obligated, or will devote his
full-time efforts, to the business of the Company. There can be no assurance
that the Company will be able to attract and retain such individuals currently
or in the future on acceptable terms, or at all. In addition, the Company does
not maintain "key person" life insurance on any officer, employee or consultant
of the Company except for Allen I. Bain, President and Chief Executive Officer.
The Company also has relationships with scientific collaborators at academic and
other institutions, some of whom conduct research at the Company's request or
assist the Company in formulating its research and development strategy. These
scientific collaborators are not employees of the Company and may have
commitments to, or consulting or advisory contracts with, other entities that
may limit their availability to the Company. In addition, these collaborators
may have arrangements with other companies to assist such other companies in
developing technologies that may prove competitive to those of the Company.

Conflicts of Interest

Certain officers and directors of the Company, namely Allen I Bain, Robert J.
Gayton and Oh Kim Sun, also serve as officers and/or directors of other
           --
companies which engage in biotechnology/pharmaceutical research and development
activities. Although there are inherent conflicts arising from an officer or
director holding such positions with more than one company (such as in
determining the allocation of the individual's time and business opportunities
presented to the individual), there are presently no specific conflicts of
interest arising from the Company and such other companies having common
insiders. To the extent that such other companies may participate in ventures
in which the Company may participate, the directors of the Company would have a
conflict of interest in negotiating and concluding terms respecting the extent
of such participation. In the event that such a conflict of interest arises at
a meeting of the directors of the Company, a director who has such a conflict
will abstain from voting for or against the approval of the matter before the
meeting. In accordance with the laws of the Province of British Columbia, the
directors of the Company are required to act honestly, in good faith and in the
best interests of the Company. In determining whether the Company will
participate in a particular program, the directors will primarily consider the
potential benefits to the Company, the degree of risk to which the Company may
be exposed and its financial position at the time. Other than as indicated, the
Company has no other procedures or mechanisms to deal with conflicts of
interest.

Exposure from Product Liability Claims

The products the Company will attempt to develop will, in most cases, undergo
extensive clinical testing and will require FDA and HPB approval prior to sale
in the United States and Canada, respectively. However, despite all reasonable
efforts to ensure safety, it is possible that products which are defective or to
which patients react in an unexpected manner, or which are alleged to have side
effects, will be sold. The sale of such products may expose the Company to
potential liability resulting from the use of such products. Additionally, the

<PAGE>
Page 32

Company may be exposed to product liability claims in the development of the
products through administration of the drug candidates to volunteers and
patients in clinical trials. Such liability might result from claims made
directly by consumers or by pharmaceutical companies or others selling such
products. It is impossible to predict the scope of injury or liability from
such defects or unexpected reactions, or the impact on the market for such
products of any allegations of these claims (even if unsupported), or the
measure of damages which might be imposed as a result of any claims or the cost
of defending such claims. Although the Company's shareholders would not have
personal liability for such damages, the expenses of litigation in connection
with any such injuries or alleged injuries and the amount of any aware imposed
on the Company in excess of existing insurance coverage, if any, may have a
material adverse impact on the Company. In addition, any liability that the
Company may have as a result of the manufacture of any products could have a
material adverse effect on the Company's financial condition, business and
operations, to the extent insurance covering any such liability is not
available. It is the Company's policy to secure product liability coverage
prior to the commencement of each product's clinical trial. The Company is
presently in the process of acquiring product liability coverage for the
upcoming Alzheimer disease clinical trials. Currently, the Company has no other
product liability insurance. It is anticipated that insurance equivalent to
that customarily maintained by other entities in the Company's industry and of
its approximate size will be carried by the Company against such product
liability claims in the future. However, obtaining insurance of al kinds has
become increasingly most costly and difficult and there can be no assurance that
any such insurance will be available at all, available on commercial terms or,
if obtained, will be sufficient to satisfy asserted claims.

Currency Fluctuations

The Company reports its financial position and results of operations in Canadian
dollars in its annual financial statements. The Company's operations result in
exposure to foreign currency fluctuations and such fluctuations may materially
affect the Company's financial position and results of operations. The Company
does not currently take any steps to hedge against currency fluctuations.

Shares Reserved for Future Issuance

As at April 30, 2000, the Company had reserved 21,977,466 Shares for issuance
upon the exercise of stock options and other rights to purchase Shares. Such
Shares represent a potential dilution of approximately 72.7% based upon
30,233,965 Shares then outstanding. (See "Item 12 - Options to Purchase
Securities From Company".) The Company may in the future enter into commitments
which would require the issuance of additional Shares and may grant additional
stock options and/or issue share purchase warrants. The Company's share capital
consists of 100,000,000 Shares. Issuance of such additional Shares is subject
to Canadian Venture Exchange approval and compliance with applicable securities
legislation.

Dividends

To date, the Company has not declared or paid dividends on its Shares and does
not anticipate doing so in the foreseeable future. Investors will only realize
economic gain on their investments from appreciation in the price of the stock.

Volatility of Share Price

The market prices for the securities of biotechnology companies have
historically been highly volatile. The market has from time to time experienced
significant price and volume fluctuations that are unrelated to the operating
performance of any particular company. (See "Item 5 - Nature of Trading
Market".) Certain factors such as announcements by the Company, competition by
new therapeutic products or technological innovations, government regulations,

<PAGE>
Page 34

fluctuations in the operating results of the Company, results of clinical
trials, public concern on safety of drugs generally, general market conditions
and developments in patent and proprietary rights can have an adverse impact on
the market price of the Shares.

Forward Looking Statements

This Registration Statement contains forward looking statements concerning the
Company's operations, economic performance and financial condition, including in
particular, the likelihood of the Company's success in operating as an
independent company and developing and expanding its business. These statements
are based upon a number of assumptions and estimates which are inherently
subject to significant uncertainties and contingencies, many of which are beyond
the control of the Company, and reflect future business decisions which are
subject to change. Some of these assumptions inevitably will not materialize,
and unanticipated events will occur which will affect the Company's future
results. All such forward looking statements are qualified by reference to
matters discussed under this section entitled "Risk Factors".

ITEM 2.   DESCRIPTION OF PROPERTY

The Company currently subleases 2000 square feet of office space for
administrative purposes in Vancouver, Canada. The sublease expires on May 31,
2001 unless extended by the Company for up to one year. The Company is required
to pay the amounts required to be paid under the head lease, the monthly total
of which is approximately $7,000.

ITEM 3.   LEGAL PROCEEDINGS

The Company is not a party to any material pending legal proceedings and is not
aware of any contemplated legal proceedings to which it may be a party.

ITEM 4.   CONTROL OF COMPANY

As far as known to the Company, the Company is not directly or indirectly owned
or controlled by another corporation or by any foreign government. The
following table sets forth certain information, as at April 30, 2000, concerning
(i) persons that are the registered owners of, or are known by the Company to
own beneficially, directly or indirectly, more than 10% of the outstanding

================================================================================

The closing price of the Shares on the Canadian Venture Exchange on Friday,
April 28, 2000 was $1.05.

There is no active trading market for the Shares in the United States, although
United States residents may purchase Shares. The following table indicates the
approximate number of record holders of Shares at September 30, 1999, the number
of record holders of Shares with United States addresses and the portion and
percentage of Shares so held in the United States. On such date, 27,939,465
Shares were outstanding.

================================================================================
 Total Number          Number of U.S.   Shares Held in         Percentage of
  of Holders             Holders           the U.S.                Shares

================================================================================

Depositories, brokerage firms and financial institutions hold a substantial
number of the Shares in "street names". Based upon enquiries made by the
Company, management of the Company estimates that the total number of beneficial
holders of Shares exceeds 702, of which approximately 42 are U.S. persons.

The Company is not aware of the distribution of any warrants to U.S. residents.
United States residents may beneficially own Shares or warrants held of record
by non-United States residents.

ITEM 6.   EXCHANGE CONTROLS AND OTHER LIMITATIONS AFFECTING SECURITY HOLDERS

There is no law or governmental decree or regulation in Canada that restricts
the export or import of capital, or affects the remittance of dividends,
interest or other payments to a non-resident holder of Shares, other than
withholding tax requirements. See "Item 7 - Taxation".

There is no limitation imposed by Canadian law or by the constituent documents
of the Company on the right of a non-resident to hold or vote Shares (the
"Voting Shares"), other than are provided in the Investment Canada Act (Canada)
(the "Investment Act"), as amended by the World Trade Organization Agreement
Implementation Act (the "WTOA Act"). The Investment Act generally prohibits

<PAGE>
Page 35

implementation of a reviewable investment by an individual, government, or
agency thereof, corporation, partnership, trust or joint venture that is not a
"Canadian", as defined in the Investment Act (a "non-Canadian"), unless, after
review, the minister responsible for the Investment Act is satisfied that the
investment is likely to be of net benefit to Canada. An investment in the
Voting Shares of the Company by a non-Canadian (other than a "WTO Investor", as
defined below) would be reviewable under the Investment Act if it were an
investment to acquire control of the Company and the company was not,
immediately prior to the implementation of the investment, controlled by a WTO
investor, and the value of the assets of the Company were $5.0 million or more.
An investment in Voting shares of the Company by a WTO investor would be
reviewable under the Investment Act if it were an investment to acquire direct
control of the company, and the value of the assets of the Company equaled or
exceeded $184 million (threshold amount for 1999). A non-Canadian, whether a
WTO Investor or otherwise, would acquire control of the Company for purposes of
the Investment Act if he or she acquired a majority of the Voting Shares of the
Company. The acquisition of less than a majority, but at least one-third of the
Voting Shares of the Company, would be presumed to be an acquisition of control
of the Company unless it could be established that the Company was not
controlled in fact by the acquirer through the ownership of the Voting Shares.
In general, an individual is a WTO Investor if he or she is a "national" of a
country (other than Canada) that is a member of the World Trade Organization
("WTO Member") or has a right of permanent residence in a WTO Member other than
Canada. A corporation or other entity will be a WTO Investor if it is a "WTO
Investor-controlled entity" pursuant to detailed rules set out in the Investment
Act. The United States is a WTO Member.

Certain transactions involving Voting Shares of the Company would be exempt from
the Investment Act, including:

   (a) an acquisition of Voting Shares of the Company if the acquisition were
       made in connection with the person's business as a trader or dealer in
       securities;
   (b) an acquisition or control of the Company in connection with the
       realization of a security interest granted for a loan or other financial
       assistance and not for the purpose related to the provisions of the
       Investment Act; and
   (c) an acquisition of control of the Company by reason of an amalgamation,
       merger, consolidation or corporate reorganization, following which the
       ultimate direct or indirect control in fact of the Company, through the
       ownership of voting interests, remains unchanged.

ITEM 7.   TAXATION

A brief description of certain provisions of the tax treaty between Canada and
the United States is included below, together with a brief outline of income
taxes, including withholding provisions to which United States security holders
who are non-residents of Canada are subject under existing laws and regulations
of Canada and the United States; the consequences, if any, of state and local
taxes are not considered. Security holders should seek the advice of their own
tax advisors, tax counsel or accountants with respect to the applicability or
effect on their own taxes. The Company has not paid dividends on the Shares in
any of its last five fiscal years, and has no plans to pay dividends in the
immediate future. For additional particulars, see "Item 8 - Selected Financial
Data - Dividend Policy".

Canadian federal tax legislation would require a 25% withholding from any
dividends paid or deemed to be paid to the Company's non-resident shareholders.
However, a company resident in the United States that beneficially owns at least
10% of the voting stock of the Company would have this rate reduced to 5%
through the tax treaty between Canada and the United States. The rate of
Canadian non-resident withholding may not exceed 15% of the dividend in the case
of United States shareholders other than as described above. The amount of
stock dividends paid to non-residents of Canada would be subject to withholding

<PAGE>
Page 36

tax at the same rate as cash dividends. The amount of a stock dividend (for tax
purposes) would be equal to the amount by which the stated capital of the
Company had increased by reason of the payment of such a dividend. Interest
paid or deemed to be paid on the Company's debt securities held by non-Canadian
residents may also be subject to Canadian withholding tax, depending upon the
terms and provisions of such securities and any applicable tax treaty.

A non-resident holder is not subject to tax in Canada in respect of a capital
gain realized upon the disposition of a Share unless the Share represents
"taxable Canadian property" to the holder thereof. The Shares will be
considered taxable Canadian property to a non-resident holder only if:

(a)  the non-resident holder;
(b)  persons with whom the non-resident holder did not deal at arm's
     length; or
(c)  the non-resident holder and persons with whom he did not deal at arm's
     length,

owned not less than 25% of the issued shares of any class or series of the
Company at any time during the five year period preceding the disposition. In
the case of a non-resident holder to whom Shares represent taxable Canadian
property and who is resident in the United States, no Canadian taxes will
generally be payable on a capital gain realized on such Shares by reason of the
Treaty unless:

(a)  the value of such Shares is derived principally from real property
     (including resource property) situated in Canada,
(b)  they formed part of the business property or were otherwise
     effectively connected with a permanent establishment or fixed base that the
     holder has or had in Canada within the 12 months preceding the disposition;
     or
(c)  the holder is a U.S. LLC which is not subject to tax in the U.S.

If subject to Canadian tax on such a disposition, the taxpayer's capital gain
(or capital loss) from a disposition is the amount by which the taxpayer's
proceeds of distribution exceed (or are exceeded by) the aggregate of the
taxpayer's adjusted cost base of the shares and reasonable expenses of
disposition. For Canadian income tax purposes, the "taxable capital gain" is
equal to three quarters of the capital gain.

This discussion is not intended to be, nor should it be construed to be, legal
or tax advice to any holder or prospective holder of Shares and no opinion or
representation with respect to the United Sates federal income tax consequences
to any such holder or prospective holder is made. Holders and prospective
holders are urged to consult their own tax advisors with respect to their
particular circumstances.

</TABLE>

  (1)  On April 24, 1996, BCFC, a public company, and Immune Network amalgamated
       and continued as the Company.  Pursuant to the Amalgamation, the former
       shareholders of BCFC received  4,263,309 Shares on a 2 new for 3 old
       basis of the amalgamated company and the former shareholders of Immune
       Network received 12,731,319 Shares on a 4 new for 3 old basis of the
       amalgamated company.  As a result, the shareholders of Immune Network
       owned more than 50% of the amalgamated company.  This business
       combination is considered a reverse acquisition of BCFC by Immune
       Network and a recapitalization of Immune Network.  Accordingly, the prior
       year financial figures presented in the Financial Statements reflect the
       accounts of Immune Network at their historical carrying amounts.
  (2)  Beginning deficit in 1996 was adjusted for net monetary liabilities
       acquired of $19,930.  Detail is provided in Note 1 to the Financial
       Statements.

Under accounting principles generally accepted in the United States ("U.S.
GAAP"), stock based compensation to non-employees must be recorded at the fair
market value of the options granted.  This compensation, determined using a
black-Scholes pricing model, is expenses over the vesting periods of each option
grant.  For the purposes of reconciliation to U.S. GAAP, the Company would
record additional compensation expense of $135,556 in the nine months ended
September 30, 1999, $162,000 in 1998 and $121,722 in 1996, in respect of options
granted to non-employees.

U.S. GAAP also requires escrow shares to be treated as contingent shares and as
such they are not included as outstanding shares for the purpose of calculating
basic earnings per share, but are included in the calculation of diluted
earnings per share if dilutive.  When released from escrow, the fair market
value of these shares will be recognized as compensatory benefit and will be
charged to income.

<PAGE>
Page 39

Under U.S. GAAP, costs incurred in connection with the reverse acquisition in
1996 totaling $155,875, net of cash received from the acquisition of $15,028,
must be charged to expense.

As at December 31, 1998 there were 5,566,667 Shares held in escrow pursuant to
the terms of an escrow agreement dated December 7, 1995 among the Company,
Montreal Trust Company of Canada, as escrow agent, and the holders of the
Shares.  The Shares may be released from escrow on a pro rata basis in
accordance with a prescribed formula based upon cumulative cash flow.  No escrow
Shares have been released to date.  Reference should be made to "Item 14 -
Description of Shares to be Registered".

To date, the Company has not paid any dividends on the Shares and it does not
expect to pay dividends in the foreseeable future.

The financial statements have been prepared in accordance with accounting
principles generally accepted in Canada ("Canadian GAAP").  These principles, as
applied to the Company, conform in all material respects to U.S. GAAP, except as
disclosed in Note 14 to the Financial Statements.  For a comparison of these
differences between Canadian GAAP and U.S. GAAP, see Note 14 to the Financial
Statements.

ITEM 9.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
            RESULTS OF OPERATIONS

General
-------

The following discussion and analysis should be read in conjunction with the
Financial Statements and related notes.  The Financial Statements are prepared
in accordance with Canadian generally accepted accounting principles.  A
discussion of differences between Canadian and United States generally accepted
accounting principles is provided in Note 14 to the Financial Statements.

Since incorporation of Immune Network as a biotechnology company, the Company
has devoted its fiscal resources primarily to fund its research and development
programs.  The Company's business remains at an early stage of development and
has been unprofitable.  The Company expects to incur additional losses for the
next several years as it invests in product research and development,
preclinical studies and clinical trials, and regulatory compliance.  The
Company's business is subject to significant risks, including uncertainties
associated with the regulatory approval process and with obtaining and enforcing
patents.  See "Item 1 - Description of Business - Risk Factors".

Subsequent to September 30, 1999, the Company completed a non-brokered private
placement  raising net proceeds of $318,000, and completed a brokered private
placement of special warrants raising net proceeds of $7,791,911, after
deducting the expenses of the offering of $708,088 (see "Description of Business
- Business of the Company" and "Options to Purchase Securities from the
Company").  Subsequent to September 30, 1999 and up to April 30, 2000, the
Company received $454,685 from the exercise of stock options.  In addition,
180,000 share purchase warrants exercisable at $0.15 per share expired,
unexercised, on December 2, 1999.  In June 2000, a shareholder of the Company
exercised its right to convert its loan to the Company in the principal amount
of $50,000 into 200,000 Shares, at a conversion price of $0.25 per Share.

Liquidity and Capital Resources
-------------------------------

The Company has financed its operations primarily through equity financings,
government grants and tax credits. From January 1, 1994 to December 31, 1998,
the Company received approximately $2,712,790 in net proceeds from the sale of
equity securities.

The Company has material financial commitments under the Bridge Pharma Agreement
and Bridge Pharma Addendum, and the CroMedica Agreement (see "Item 1 -
Description of Business - Material Agreements - Bridge Pharma, Inc." and "Item 1
- Description of Business - Material Agreements - CroMedica Global Inc.").  The
Company is still negotiating the terms of the license agreement with the
University of British Columbia (see "Item 1 - Description of Business - Material
Agreements - University of British Columbia"), and does not expect the license
fee and other amounts to be payable under the proposed agreement to be material.

The Company does not anticipate revenues from product sales for the foreseeable
future.  Over the next several years, through preclinical development and the
early clinical stages of development, the Company expects to derive its sources
of funding primarily from equity financing.  Additional funding may be obtained
through interest income.  The long term sustainability of the Company is
expected to be achieved through collaborative and licensing arrangements and the
creation, development and ultimate disposition of intellectual property.
Although no such arrangements have yet been negotiated, it is likely that all or
a portion of the payments that may be received under such agreements will be
conditional upon the Company reaching developmental milestones.  As much as
possible, the disposition of intellectual property is intended to be carried out
so as to ensure an appropriate balance between future earnings potential and
current liquidity.

Nine Month Period Ended September 30, 1999

In February 1999 the Company completed a non-brokered private placement of
360,000 units at $0.15 per unit, each unit consisting of one Share and one share
purchase warrant exercisable for one year to purchase one additional Share at
$0.15.  In July 1999 the Company completed two non-brokered private placements
raising gross proceeds of $942,977.  In connection with these private
placements, a total of 6,286,513 share purchase warrants were issued, each
warrant exercisable to purchase one Share at $0.15 in the first year and $0.18
in the second year.  During the period the Company also raised $116,175 from the
exercise of options ($93,750) and warrants ($22,425).

There were no material commitments for capital expenditures as at September 30,
1999.

Year Ended December 31, 1998

During Fiscal 1998, the Company completed a private placement of 400,000 units
for total proceeds of approximately $80,000.  Each unit consisted of one Share
and one share purchase warrant exercisable for one year to purchase one Share at
$0.20.  At December 31, 1998, the Company had a working capital deficit of
approximately $48.  During the year the Company disposed of all of its capital
assets consisting of laboratory and office equipment to a private company.  The
Company determined that its assets were no longer necessary in view of its
contract with ImmPheron under which ImmPheron was required to conduct
preclinical trials.  The Company recognized a loss on the disposition of $4,673.
There was no material commitments for capital expenditures as at December 31,
1998.

<PAGE>
Page 41

Year Ended December 31, 1997

There were no share capital transactions during Fiscal 1997.

Year Ended December 31, 1996

During Fiscal 1996, the Company raised approximately $572,620 pursuant to a
private placement of 1,590,611 at $0.36 per Share.  This financing was done
before the amalgamation of Immune Network and BCFC on April 24, 1996.  The
Company raised an additional $825,000 in a post-amalgamation private placement
of 1.5 million units, each unit consisting of one Share and one share purchase
warrant exercisable for one year to purchase one Share at $0.55.

Results of Operations
---------------------

Nine Month Period Ended September 30, 1999

Beginning June 1999 the Company resumed research activities for Antibody 1F7
which included the completion of viral load testing on blood samples from
previous studies and the compilation of existing data in preparation for
regulatory review.  During 1998 research activities had been scaled down due to
lack of funding and staff to carry out research.

During the second-half of Fiscal 1999, the Company exercised its option to
license the Alzheimer drug candidates (see "Item 1 - Description of Business -
Material Agreements - University of British Columbia") and entered into a joint
venture agreement regarding the development of a new asthma therapeutic (see
"Item 1 - Description of Business - Material Agreements - Bridge Pharma, Inc.").
The Company carried out research in the form of due diligence on these
technologies and also began preparations for clinical testing of the Alzheimer
Disease Project (AD2).

During the nine month ended September 30, 1999, the Company reported a net loss
of $323,827 ($0.014 per Share) as compared to $110,139 ($0.005 per Share) for
the same period in 1998.  For the nine months ended September 30, 1999 the
Company expended $159,183 on its research activities as compared to $24,407
during the nine months ended September 30, 1998.  The increase in research and
development expenditures was primarily due to the commencement of the Alzheimer
disease project in July 1999 and costs incurred prior to commencement of the
Asthma joint venture, which required the Company to increase its staff and
space, and to enhance its infrastructure (website), which directly attributed to
increases in salaries and benefits ($65,506), consultants ($34,957), rent
($10,485) and computer support and maintenance ($24,607).  For the nine months
ended September 30, 1999, the Company expended $175,947 in its administrative
activities as compared to $86,271 during the nine months ended September 30,
1998.  The increase in administrative expenses was primarily due to increase in
salaries and benefits ($42,494) as related to management change and hiring of
staff, legal and accounting ($35,236), computer support and maintenance
($8,212), and interest  ($4,500) on shareholder's loan.

At October 1, 1999, management revised the estimated useful lives of its
technology and license from 17 years to an estimated remaining life of five
years and from 20 years to an estimated remaining life of 5 years for patents,
after considering such factors as the competition levels and the rate of
technological change in those areas where the Company's technologies are
focused, the Company's present stage of development of its research activities
and the accounting practices of comparable companies in similar stages of
development.  This change in estimate will be accounted for on a prospective
basis and will result in additional amortization expense for the quarter ended
December 31, 1999 of approximately $10,000 and approximately an additional
$20,000 amortization expense for the year ending December 31, 2000.

<PAGE>
Page 42

Year Ended December 31, 1998

During Fiscal 1998, the Company reported a net loss of $201,671 ($0.010 per
Share) as compared to $262,744 ($0.013 per Share) during Fiscal 1997.  During
Fiscal 1998, the Company expended $31,055 in its research activities as compared
to $77,548 during Fiscal 1997.  The decrease in research expenditures in 1998
was attributable to the research agreement between the Company and ImmPheron,
Inc. during the fourth quarter of 1997 wherein ImmPheron Inc. was required to
fund US$81,000 towards a live animal trial of the Antibody 1F7 program in 1998
in order to earn its 50% interest.  For Fiscal 1998, the Company expended
$166,855 in its administrative activities as compared to $147,618 during Fiscal
1997.  Advertising expense increased by $31,076 as the Company increased its
advertising expenditures in 1998 in an effort to raise capital to fund further
operations.  The Company entered into an investor relations contract with an
arm's length party in August 1998 at a fee of $4,000 per month.  The contract
was terminated in December of 1998 due to reduced cash flow.  In addition, the
Company took out several advertisements in an attempt to raise capital.  Legal
fees decreased by $26,424 (from $28,243 to $1,819) and accounting fees decreased
by $4,265 (from $20,044 to $15,779), as considerable fees were incurred in 1997
as related to a proposed asset sale.  During the year, the Company disposed of
all of its capital assets consisting of laboratory and office equipment to a
private company.  The Company determined that its assets were no longer
necessary in view of its contract with ImmPheron Inc.  The Company recognized a
loss on the disposition of $4,673.

Year Ended December 31, 1997

During Fiscal 1997, the Company reported a net loss of $262,744 ($0.013 per
Share) as compared to $825,674 ($0.048 per Share) during Fiscal 1996.  Included
in the net loss figure for Fiscal 1997 was a $38,965 loss arising upon the
finalization of a sale to a minority shareholder of technologies, comprised of a
patent and two patent applications, no longer being pursued by the Company (see
discussion under "Year Ended December 31, 1996"). During Fiscal 1997, the
Company expended $147,618 on administrative expenses as compared to $476,943
during Fiscal 1996.  The significant decrease in administration expenses was
attributable to costs associated with the amalgamation in Fiscal 1996 of Immune
Network and BCFC and scaled back its expenditures in 1997 due to cash flow
considerations.

Advertising expense decreased by $20,196, and of the $24,369 incurred for
advertising in 1996, approximately $16,500 was paid to an arm's length party for
public relations in connection with an AIDS conference held in Vancouver.  The
balance was paid pursuant to an investor relations contract.  Legal fees
increased by $11,171 (from $17,072 to $28,243) relating largely to a proposed
sale of assets of the Company which was ultimately abandoned in 1997.
Accounting fees decreased by $18,320 (from $38,364 to $20,044).  The 1996
accounting fees represent higher audit fees associated with the Company's
amalgamation.

During Fiscal 1997, the Company expended $77,548 in its research activities as
compared to $348,734 during Fiscal 1996.  This decrease of $271,186 in research
and development expenditures can be primarily attributed to the decrease in
scientific collaboration ($83,310), research salaries and benefits ($88,883) and
consulting fees ($69,113).

Year Ended December 31, 1996

During Fiscal 1996, the Company reported a net loss of $825,674 ($0.048 per
Share) as compared to $559,444 ($0.053 per Share) during Fiscal 1995.  Included
in the December 31, 1996 figure was $60,180 in a write-down of intangible
assets.  During 1996 the Company decided to change its focus and devote its
resources to its most promising technology, antibody 1F7.  Accordingly, the
Company reviewed the costs associated with those technologies no longer being
pursued and wrote them down by $60,180 to their estimated net realizable value.

<PAGE>
Page 43

This estimate was based on preliminary discussions with a minority shareholder
who expressed an interest in acquiring these technologies.

In 1997 the Company concluded its transaction with the minority shareholder
resulting in a further write-down of $38,965.

During Fiscal 1996, the Company expended $348,734 ($370,211 in 1995) in research
activities, and $476,943 ($286,233 in 1995) in administration expenses.  The
significant increase in administration expenses from Fiscal1995 to Fiscal 1996
($190,710) was attributable to the costs associated with the amalgamation of
Immune Network and BCFC.

ITEM 9A.     MARKET RISK

Interest Rate Risk

In June 2000, a shareholder of the Company exercised its right to convert its
loan to the Company in the principal amount of $50,000 into 200,000 Shares, at a
conversion price of $0.25 per Share.  The Company was subject to interest rate
risk on the $50,000 shareholder loan, which carried a fixed annual rate of 12%.

Foreign Currency Risk

The Company reports its financial position and results of operations in Canadian
dollars in its annual financial statements.  The Company's operations result in
exposure to foreign currency fluctuations and such fluctuations may materially
affect the Company's financial position and results of operations.  The Company
does not currently take any steps to hedge against currency fluctuations.

The Company's primary exposure risk is due to fluctuations in the US dollar.
For the nine months ended September 30, 1999, a uniform 10% strengthening in the
value of the US dollar relative to the Canadian dollar would result in an
increase in the loss and cash outflow of $5,139 due to the settlement of
accounts payable and transactions which are denominated in US dollars.  For the
year ended December 31, 1998, a uniform 10% strengthening in the value of the
US dollar relative to the Canadian dollar would result in an increase in loss
and cash outflow of $2,680 due to the settlement of accounts payable and
transactions which are denominated in US dollars.

ITEM 10.    DIRECTORS AND OFFICERS OF THE COMPANY

Special Warrants

As at April 30, 2000, the Company has reserved 17,574,544 Shares for issuance at
no additional cost upon exercise of special warrants, described as follows.

On January 24, 2000, the Company completed a private placement of 2,120,000
special warrants (the "January 2000 Special Warrants") at a price of $0.15 each.
Each January 2000 Special Warrant will be converted into one unit comprised of
one Share and one share purchase warrant.  Each share purchase warrant entitles
the holder to purchase one Share (for a total of 2,120,000 Shares) at a price of
$0.15 until January 23, 2001 and at $0.17 from January 24, 2001 until January
23, 2002.

On March 9, 2000, the Company completed a private placement of 15,454,544
special warrants (the "March 2000 Special Warrants") at a price of $0.55 each.
Upon the exercise or deemed exercise of the March 2000 Special Warrants, each
March 2000 Special Warrant will be converted into one unit comprised of one
Share and one-half of one share purchase warrant.  Each whole share purchase
warrant entitles the holder to purchase one Share (for  a total of 7,727,272
Shares) at a price of $1.40 until September 8, 2001.  An additional 2,318,181
Shares, including an additional 772,727 Shares issuable upon exercise of the
share purchase warrants, are reserved for issuance upon the exercise or deemed
exercise of the March 2000 Special Warrants in the event that receipts for a
prospectus are not obtained from the Securities Commissions in each of the
Provinces of British Columbia, Alberta, Ontario and Quebec qualifying the
distribution of the securities upon exercise of the March 2000 Special Warrants
by July 7, 2000.  The March 2000 Special Warrants are identical in all respects

<PAGE>
Page 46

and subject to the terms of a special warrant indenture dated March 9, 2000,
entered into between the Company and Montreal Trust Company of Canada, as
trustee (the "Special Warrant Indenture"), and include the following terms and
conditions:

1.  no fractional Shares will be issued; holders of special warrants may be
    entitled to cash payment in respect of fractional entitlements;

2.  the March 2000 Special Warrants, including the number of Shares issuable
    upon exercise or deemed exercise thereof, may be subject to adjustment upon
    the occurrence of certain stated events, including the subdivision or
    consolidation of Shares, certain distributions of Shares, or securities
    convertible into or exchangeable for Shares, or of other securities or
    assets of the Company, certain offerings of rights, warrants or options and
    certain capital reorganizations;

3.  the holding of March 2000 Special Warrants will not give the holder rights
    as a shareholder of the Company; and

4.  March 2000 Special Warrants may be exercised by the holder at any time to
    and until the earlier of 4:30 p.m. (Vancouver time) on the earlier of
    September 8, 2001 and the fifth business day following the date on which the
    final receipts issued by the applicable securities commissions for the
    prospectus qualifying the distribution of the units on exercise of the March
    2000 Special Warrants (together with the agent's compensation options on
    exercise of the Agent's Special Warrants) have all been issued (the "Expiry
    Time"), and March 2000 Special Warrants not exercised by the Expiry Time
    shall, immediately prior to the Expiry Time, be deemed to have been
    exercised without any further action on the part of the holder.

For US GAAP accounting purposes, the proceeds of the special warrants received
are allocated to the common shares and share purchase warrants based on their
relative fair values.  The fair value of the common shares will be equal to the
quoted trading price of the common shares and the fair value of the share
purchase warrants will be determined using the Black-Scholes pricing model.  The
total fair value of the common shares and the share purchase warrants will not
exceed the gross proceeds received.  For Canadian GAAP purposes, the proceeds
are generally not allocated.

Agent's Special Warrants

The Company has issued 1,545,454 agent's warrants (the "Agent's Special
Warrants") in relation to the sale of the March 2000 Special Warrants described
above.  Each Agent's Special Warrant is exercisable at no additional cost into
one compensation option (the "Agent's Compensation Option").  Each Agent's
Compensation Option will entitle the holder to acquire one unit (the "Agent's
Unit") at a price of $0.55 each.  Each Agent's Unit will be exercisable into one
Share and one-half of one share purchase warrant (the "Agent's Unit Warrants").
Each whole Agent's Unit Warrant will entitle the holder to acquire one
additional Share at a price of $1.40 each until September 8, 2001.  All of the
Agent's Special Warrants are identical in all respects and include the following
terms and conditions:

1.  no fractional Shares will be issued; the holder of the Agent's Special
    Warrants may be entitled to cash payment in respect of fractional
    entitlements;

2.  the Agent's Special Warrants, including the number of Shares issuable
    upon exercise or deemed exercise thereof, may be subject to adjustment upon
    the occurrence of certain stated events, including the subdivision or
    consolidation of Shares, certain distributions of Shares, or securities
    convertible into or exchangeable for Shares, or of other securities or
    assets of the Company, certain offerings of rights, warrants or options and
    certain capital reorganizations;

<PAGE>
Page 47

3.  the holding of Agent's Special Warrants will not give the holder rights as a
    shareholder of the Company; and

4.  the Agent's Special Warrants may be exercised, for no additional
    consideration, at any time prior to the Expiry Time, and any Agent's Special
    Warrants not exercised by the Expiry Time shall, immediately prior to the
    Expiry Time, be deemed to have been exercised into agent's compensation
    options without any further action on the part of the holder.

The fair value of the warrants issued to the agent as compensation for the
private placement of the 15,454,544 special warrants has been estimated at
$480,000.  The fair value has been estimated using the Black-Scholes pricing
model with the following assumptions: a risk free interest rate of 6%; a
dividend yield of 0%; a volatility factor of the expected market price of the
Company's common stock of 1.084 and an average expected life of the warrant of
0.75 years.  This cost will be recorded as a share issue cost.

ITEM 13.  INTEREST OF MANAGEMENT IN CERTAIN TRANSACTIONS

To the knowledge of current management, no director or officer of the Company or
any shareholder holding of record or beneficially, directly or indirectly,
owning more than 10% of the issued and outstanding Shares, or any of their
respective associates or affiliates or any relative or spouse of any of the
foregoing who has the same home, has had any material interest, directly or
indirectly, in any material transaction with the Company, or in any proposed
material transaction, since January 1, 1996.

Pursuant to a Loan Agreement dated September 13, 1999, Allen I. Bain, President,
CEO and a director of the Company, borrowed approximately $34,000 from the
Company.  Interest was charged on the principal sum outstanding in an amount
equal to the rate of interest in effect from time to time as prescribed by
Revenue Canada.

The Company subleases its office premises from Allen I. Bain, the President, CEO
and a director of the Company.  The sublease expires on May 31, 2001 and may be
extended by the Company for an additional year.  The Company is required to pay
the amounts under the head lease required to be paid by Dr. Bain, the monthly
total of which is approximately $7,000.

ITEM 14.     DESCRIPTION OF SECURITIES TO BE REGISTERED

The shares to be registered are the Company's common shares without par value.

As at April 30, 2000, the authorized capital of the Company consists of
100,000,000 Shares of which 30,233,965 were issued as fully paid and
non-assessable.  In addition, on such date, 37,432,010 Shares were reserved for
issuance against the exercise of outstanding stock options and other rights to
acquire Shares (see "Item 12 - Options to Purchase Securities from the
Company").

Shares

The holders of Shares are entitled to vote at all meetings of shareholders of
the Company, to receive dividends if and when declared by the directors, and
subject to the rights of the holders of any Shares ranking in priority to or on
parity with the Shares, to receive the remaining property and assets of the
Company in the event of liquidation, dissolution or winding up of the Company.
The Shares have no pre-emptive, redemption, purchase or conversion rights.
There are no sinking fund provisions in relation to the Shares and they are not
liable to further calls or to assessment by the Company.  The British Columbia
Company Act provides that the rights and provisions attached to any class of
shares may not be modified, amended or varied unless consented to by special
resolution passed by a majority of not less than 3/4 of the votes cast in person
or by proxy by holders of shares of that class.

<PAGE>
Page 48

The Company has not declared or paid any dividends on its outstanding Shares
since its inception and does not anticipate that it will do so in the
foreseeable future.  The declaration of dividends is within the discretion of
the Company's board of directors.  The Company is limited in its ability to pay
dividends on its Shares by limitations under British Columbia law relating to
the sufficiency of profits from which dividends may be paid.

Escrow Shares

There are 5,566,667 Shares (the "Escrow Shares") deposited with Montreal Trust
Company of Canada (the "Escrow Agent") pursuant to an escrow agreement dated
December 7, 1995 (the "Escrow Agreement").  The Escrow Agreement provides that
the Escrow Shares may not be traded in or released, nor may the Company, its
transfer agent or escrow holder make any transfer or record of any trading of
the Escrow Shares without the consent of the executive director of the British
Columbia Securities Commission or, while the Shares are listed on the Canadian
Venture Exchange, the consent of the Canadian Venture Exchange.

The release of the Escrow Shares is based upon a prescribed formula.  Escrow
Shares, while not freely tradeable, carry voting rights equal to those of all
other Shares.  While not freely tradeable, Escrow Shares may be transferred
within escrow between principals of a listed company provided that consent is
first obtained from the Canadian Venture Exchange.  If a holder of Escrow Shares
ceases to be a principal of the Company, such holder shall be entitled to retain
ownership of the Escrow Shares and shall not be required to transfer same.

The Escrow Agreement provides that the Escrow Shares must be surrendered to the
Company for cancellation:

(a) at the time of a major reorganization of the Company, if required as a
    condition of the consent to the reorganization by the Canadian Venture
    Exchange;

(b) where the Shares have been subject to a cease trade order issued under the
    British Columbia Securities Act for a period of two consecutive years; or

(c) April 24, 2006.

IMMUNE NETWORK RESEARCH LTD.
NOTE TO INTERIM STATEMENTS
(unaudited - prepared by management)
(expressed in Canadian Dollars)

1.     In the opinion of management of the Company, the unaudited financial
statements reflect all adjustments, which consist only of normal and recurring
adjustments, necessary to present fairly the financial position at September 30,
1999 and the results of operations and cash flows for the nine month periods
ended September 30, 1999 and 1998, in accordance with accounting principles
generally accepted in Canada (see note 3).  In these financial statements, the
Company has adopted the new recommendations of the Canadian Institute of
Chartered Accountants Handbook for cash flow statements.  Accordingly, the
Company now excludes non-cash investing and financing transactions in the
statement of cash flows.  The impact of the adoption of the new recommendations
did not have any impact on the comparative figures.  These financial statements
should be read in conjunction with the financial statements and notes thereto
contained in the Company's audited financial statements for the year ended
December 31, 1998.

-------------------------------------------------------------------------------

Of the 360,000 common shares issued for cash pursuant to private placement,
$45,000 cash was received prior to December 31, 1998.

3.     Reconciliation of generally accepted accounting principles.

The financial statements have been prepared in accordance with accounting
principles generally accepted in Canada which, in the case of the Company,
conform in all material respects with accounting principles generally accepted
in the United States ("U.S. GAAP"), except as fully described in Note 14 to the
audited financial statements as at December 31, 1998.  The following table
reconciles the loss and loss per share as reported on the statement of loss and
deficit to the loss that would have been reported had the financial statements
been prepared in accordance with U.S. GAAP:

4.     Patents, license and technology

Commencing October 1, 1999, management revised the estimated useful lives of
its technology and license from 17 years to an estimated remaining life of 5
years, and from 20 years to an estimated remaining life of 5 years for patents,
after reviewing current industry information.  This change in estimate will be
accounted for on a prospective basis and will result in additional amortization
expense for the quarter ended December 31, 1999 of approximately $10,000.

In addition, the Company has commitments under the Joint Venture Agreement with
Bridge Pharma, Inc. (note 6b)

b]     Uncertainty due to Year 2000

The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year.  Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information using
year 2000 dates is processed.  In addition, similar problems may arise in some
systems which use certain dates in 1999 to represent something other than a
date.  Although the change in date has occurred, it is not possible to conclude
that all aspects of the Year 2000 Issue that may affect the entity, including
those related to customers, suppliers, or other third parties have been fully
resolved.

6.     Significant Agreements

a]     License Agreement with the University of British Columbia

Pursuant to its exercise of  an option granted under an arms length agreement,
the Company has exercised an option granted by the University of British
Columbia ("UBC") for the world-wide license to use and sublicense certain
technology for the treatment of Alzheimer's disease, and the manufacture,
distribution and sale of products based on such technology.  A formal license
agreement is currently being negotiated by the Company and UBC which is to
include the following material terms:

i]   an initial, non refundable, license fee will be payable upon execution of
     the license agreement;
ii]  payments will be made to UBC upon reaching certain milestones;
iii] a royalty will be paid to UBC based upon the total gross revenue derived
     from the sale of products using the technology;
iv]  an annual, non-refundable, license maintenance fee of $1,000 will be paid
     in advance to UBC;
v]   the license agreement will terminate with respect to any patent and
     royalties applicable thereto, on the expiration or invalidity of the
     patent, and with respect to the know-how and all other rights, on the later
     to occur of expiration or invalidity of the last patent, if any, licensed
     under the license agreement or ten years.

6.     Significant Agreements

b]     Joint Venture Agreement with Bridge Pharma, Inc.

By an arms length agreement dated  August 12, 1999 with Bridge Pharma, Inc.
("BPI"), the Company has entered into a joint venture arrangement, on a 50-50
basis, with BPI for the development of a new asthma therapeutic.  In order to
retain its 50% interest, the Company is required to provide up to $2 million in
funding to the project over a period of two years.  Any additional costs above
the first US$2 million will be shared equally between the parties.

The Bridge Pharma joint venture did not commence operations until October 1999
and, accordingly, has no accounting impact on the financial statements
presented.

The Company will account for the investment in the joint venture using the
proportionate method of consolidation.  While under U.S. GAAP investments in
joint ventures are required to be accounted for under the equity method, under
rules promulgated by the Securities Exchange Commission, a foreign registrant
may, subject to the provision of additional information, continue to follow
proportionate consolidation for purposes of registration and other filings
notwithstanding the departure from U.S. GAAP.  The required additional
information concerning the Company's interest in the joint venture will be
presented in a note to the financial statements.


7.     Subsequent Events (to December 31, 1999)

a]     On December 3, 1999 the Company announced a non-brokered private
placement of 2,120,000 special warrants at $0.15 per warrant for gross proceeds
of $318,000.  Each warrant is convertible into one unit which is comprised of
one common share and one purchase warrant.  Each purchase warrant entitles the
holder to acquire one common share at $0.15 up to January 23, 2001 and at $0.17
up to January 23, 2002.  The private placement closed in January, 2000.

b]     By letter of agreement dated December 20, 1999, the Company reacquired
the 50% interest in the Antibody 1F7 acquired by Immpheron, Inc., in
consideration of the following to ImmPheron:

i]    US$4,000 on execution of the agreement;
ii]   US$2,000 on each of January 31, February 29, March 31 and April 30, 2000;
iii]  US$88,000 on July 20, 2000;
iv]   US$10,000 within 30 business days of the commencement of a Phase 1
      Clinical trial; and
v]    a  4% royalty on net earnings from the Antibody 1F7.

                                AUDITORS' REPORT




To the Directors of Immune Network Research Ltd.

I have audited the balance sheet of Immune Network Research Ltd. (a development
stage enterprise) as at December 31, 1998 and 1997, and the statements of loss
and deficit and cash flows for the years ended December 31, 1998 and for the
period from February 25, 1991 (date of inception) to December 31, 1998. These
financial statements are the responsibility of the company's management. My
responsibility is to express an opinion on the financial statements based on my
audit.

I conducted my audits in accordance with auditing standards generally accepted
in Canada.  Those standards require that I plan and perform an audit to obtain
reasonable assurance whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.

In my opinion, these financial statements present fairly, in all material
respects, the financial position of the Company as at December 31, 1998, and the
results of its operations and its cash flow for the years ended December 31,
1998 and 1997, and for the period from February 25, 1991 (date of inception)
through December 31, 1998, in accordance with principles generally accepted in
Canada.

                   Comments by Auditor for U.S. Readers on
                       Canada-U.S. Reporting Difference


In the United States, reporting standards for auditors require the addition of
an explanatory paragraph (following the opinion paragraph) when the financial
statements are affected by conditions and events that cast substantial doubt on
the company's ability to continue as a going concern, such as those described in
Note 1 to the financial statements.  My report to the shareholders dated
February  12, 1999 is expressed in accordance with Canadian reporting standards
which do not permit a reference to such events and conditions in the auditor's
report when these are adequately disclosed in the financial statements.  (See
Note 1).

IMMUNE NETWORK RESEARCH LTD.
(A development stage enterprise)
Notes to the Financial Statements
December 31, 1998 and 1997
--------------------------------------------------------------------------------
1.   Nature of operations

     a.  The Company is in the development stage and currently derives no
         revenues from its operations. The Company's ability to remain as a
         going concern is dependent on additional capital being raised to fund
         its future operations and on-going research and development activities.
         The Company has inadequate working capital to continue operations for
         the year. It is not possible to predict whether financing efforts will
         be successful or whether the Company will be able to secure the
         necessary research agreements in order to continue its operations.

         The financial statements have been prepared assuming the Company will
         continue as a going concern. Accordingly, the financial statements do
         not give effect to adjustments that would be necessary should the
         Company not be able to continue as a going concern and, therefore, be
         required to realize its assets and liquidate its liabilities in other
         than the normal course of business and at amounts different from those
         in the accompanying financial statements.

     b.  Amalgamation and continuing entity

         Effective April 24, 1996, Bobby Cadillac's Food Corporation ("BCFC"), a
         public company, and Immune Network Research Ltd. ("INR") amalgamated
         and continued as Immune Network Research Ltd. ("INRL"). Pursuant to the
         amalgamation, the former shareholders of BCFC received 4,263,309 common
         shares on a 2 new for 3 old basis of the amalgamated company and the
         former shareholders of INR received 7,664,652 common shares and
         5,066,667 shares in escrow (for a total of 12,731,319) on a 4 new for 3
         old basis of the amalgamated company. The escrowed shares represent the
         equivalent number of INR shares that were held in escrow prior to the
         amalgamation. These shares will be released from escrow on a pro-rata
         basis based on a prescribed formula based on operating cash flow. At
         the date of the amalgamation BCFC was an inactive company with net
         monetary liabilities of $19,930. As a result, the shareholders of INR
         owned more than 50% of the amalgamated company. This business
         combination is considered a reverse acquisition of BCFC by INR and a
         recapitalization of INR. Accordingly these financial statements are a
         continuation of the financial statements of INR and reflect the assets,
         liabilities, shareholders' equity, revenues and expenses of INR at
         their historical amounts. The number of common shares outstanding is a
         continuation of BCFC.  The business combination resulted in the
         acquisition of net monetary liabilities of $19,930 which has been
         charged to deficit as follows:

--------------------------------------------------------------------------------
         Net monetary liabilities acquired:

         Total assets acquired (including cash of $15,028)   $  16,561
         Total liabilities assumed                             (36,491)
--------------------------------------------------------------------------------
                                                             $ (19,930)
--------------------------------------------------------------------------------

         The reverse acquisition resulted in approximately $150,973 of one-time
         costs which were paid by the issuance of shares. The costs of
         recapitalization have been charged against shareholders' equity.

         The amalgamation was done concurrently with a public offering of
         1,500,000 shares at $0.55 per share.

         There was no goodwill on the acquisition. BCFC ceased operations
         subsequent to the amalgamation.

2.   Summary of significant accounting policies

The financial statements have been prepared in accordance with accounting
principals generally accepted in Canada. A reconciliation of amounts presented
in accordance with United States generally accepted accounting principles is
detailed in Note 14. Because a precise determination of many assets and
liabilities is dependent upon future events, the preparation of financial
statements necessarily involves the use of management's estimates and
approximations. Actual results could differ from those estimates.

The following is a summary of significant accounting policies used in
preparation of the financial statements:

     a. Capital assets

        Capital assets are recorded at cost. Depreciation is provided on a
        declining balance basis over the expected useful lives of the assets at
        the following annual rates:

                          Office equipment   20 %
                          Computers          30 %

        Depreciation is reduced to one half the normal rate in the year of
        acquisition for the respective assets.

     b. Intangible assets

        Intangible assets are recorded at the lower of cost or net realizable
        value. Amortization of intellectual property is provided on a straight
        line basis over 20 years. The patent is amortized over the life of the
        patent which is 17 years from the date of issuance.

        Management continually evaluates whether circumstances have occurred
        indicating the remaining estimated useful life of intangible assets may
        warrant revision, or may not be recoverable. If management subsequently
        determines that successful development of products to which the
        intangible assets relate is not reasonably certain, or that intangible
        costs exceed recoverable value based on estimated future net cash flows,
        such costs are charged to operations.

     c. Loss per share

        Loss per share is calculated based on the weighted average number of
        shares outstanding including shares held in escrow. Fully diluted loss
        per share is not presented as the effect of an exercise of outstanding
        share purchase options is anti-dilutive.

     d. Research and development costs

        Research costs are expensed as incurred. Direct costs and applicable
        overhead incurred in the development process are deferred only if they
        meet criteria prescribed by generally accepted accounting principals for
        deferral and amortization. The company assesses whether it has met the
        relevant criteria for deferral and amortization at each reporting date.
        No development costs have been deferred to date.

--------------------------------------------------------------------------------

     e. Advertising costs

        Advertising costs are expensed as incurred.

3.  Share capital to be issued

Share capital to be issued consists of amounts received and receivable in
advance of the issuance of shares. During the year the Company received $45,000
for 360,000 at $.15 per share. The balance of $9,000 was received subsequent to
year end. (See subsequent event note 12).

4.   Capital assets

--------------------------------------------------------------------------------
                                                       1998             1997

       capital assets                                   (7,618)            -
     Less: loss on disposal of capital assets           (4,673)            -

     ---------------------------------------------------------------------------

During the year the Company disposed of its computer and laboratory equipment to
a private company owned by two of the Company's research consultants.  A loss
of $4,673 was incurred on the transaction.

5.   Intangible assets

Intangible assets consists of patents, filings in respect of patent applications
and intellectual property.

On December 15, 1998 the Company was issued U.S. Patent Number 5,849,583 titled
Anti-idiotypic antibody and its use in diagnosis and therapy in HIV-related
disease. The patent has a life of 17 years from the date of issuance.

During 1996, the Company evaluated its portfolio of technologies and decided to
change its direction. At that time, the Company reviewed the carrying value of
the intangible assets associated with these technologies no longer being pursued
and accordingly wrote down the carrying value to their estimated realizable
values. An impairment of $60,180 was recognized in the financial statements.

During 1997, the Company sold one patent and two applications relating to these
technologies to a minority shareholder resulting in a further write down of
$38,965.


--------------------------------------------------------------------------------
                                                       1998             1997
--------------------------------------------------------------------------------

     Intangible assets                              $   202,529      $  188,507
     Less: accumulated amortization                     (55,067)        (44,968)
     ---------------------------------------------------------------------------
                                                    $   147,462      $  143,609

6.   Research Agreement

During 1997 the Company entered into a research agreement with ImmPheron Inc., a
U.S. private research corporation ("ImmPheron"). The agreement provides that, in
addition to other terms, ImmPheron will earn a fifty percent interest in certain
of the Company's intellectual property, provided it completes a budgeted
research program and a formal report on the research suitable for publication in
a scientific journal by December 31, 1998. The terms of this agreement were
extended to March 31, 1999 by mutual agreement. The ultimate percentage of
ownership in the Company's intellectual property will also depend on each
party's ability to fund further research.

7.   Loan payable to shareholder

During the year the Company borrowed $50,000 (the "Principal") from a
shareholder who holds less than 10% of the outstanding shares of the Company.
The loan plus any unpaid interest is due on or before June 15, 2001. The loan
bears interest at 12% to be paid quarterly. As at year end, $3,371 of interest
has been accrued on the loan.

The lender may, at any time, convert the Principal to common shares of the
Company at a price of $.15 per share. The conversion price will increase by
$.05 per share each year. The Company can request conversion at any time after
June 15, 1999.

8.   Commitments and contingent liabilities

     a.   University of British Columbia
          ------------------------------

     The research agreement with the University of British Columbia expired on
     December 31, 1996. The Company currently has an outstanding balance owing
     of $18,700.

     b.   Sidney Kimmel Cancer Center- (formerly San Diego Regional Cancer
          ---------------------------
          Centre)
          -------

     Under an exclusive licensing agreement entered into during 1993, the
     Company is required to pay to the Sidney Kimmel Cancer Centre a royalty
     equal to 2% of net sales of therapeutic licensed products and 5% of net
     sales of diagnostic licensed products resulting from 1F7 Antibody
     technology. In accordance with the joint research agreement (Note 6), this
     cost will be a cost to the joint research in the event that ImmPheron
     becomes entitled to a fifty percent interest in certain of the Company's
     intellectual property.

     c.   Contingent liability
          --------------------

     The Company was included as a defendant with the Genesis Group in an action
     in the Supreme Court of British Columbia regarding an alleged unpaid
     finders fee.  Management is of the view, the action is without merit and
     believes no liability will result from this action. Accordingly, no
     liability has been recorded in the financial statements.

9.   Share capital

     a.   Authorized
          100,000,000 common shares without par value.
          (25,000,000 common shares without par value -1995)

     b.   The following table gives effect to the reverse acquisition and
          recapitalization of INR as described in Note 1.

     d.   5,566,667 (1997 - 5,566,667) shares are held in escrow subject to the
          direction and determination of the Vancouver Stock Exchange. The
          release of the shares is subject to the Company's cumulative cash flow
          as defined in the Escrow Agreement. Any escrow shares not released by
          April 24, 2006, will be cancelled.

10.  Refundable investment tax credits

In 1996, the Company became a public company and as such is no longer eligible
to claim refundable investment tax credits on current expenditures. In 1996,
the Company received $339,500 in investment tax credits relating to 1994 through
1996. There are no further claims for refundable tax credits outstanding.

11.  Income tax losses

At December 31, 1998, the Company has operating losses of $1,698,668 expiring as
follows, which may be carried forward to apply against future years income for
Canadian income tax purposes, subject to final determination by taxation
authorities.

12.  Subsequent events

Subsequent to year end the Company received approval from the Vancouver Stock
Exchange for a private placement of 360,000 shares together with one year
warrants for the purchase of 180,000 additional shares all at a price of $.15
per share. $45,000 was received during the year (Note 3).

13.  Uncertainty due to the Year 2000 Issue

The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information using
year 2000 dates is processed. In addition, similar problems may arise in some
systems which use certain dates in 1999 to represent something other than a
date. The effects of the Year 2000 Issue may be experienced before, on, or
after January 1, 2000, and, if not addressed, the impact on operations and
financial reporting may range from minor errors to significant systems failure
which could affect the Company's ability to conduct normal business operations.
It is not possible to be certain that all aspects of the Year 2000 Issue
affecting the Company, including those related to the efforts of customers,
suppliers, or other third parties, will be fully resolved.

14.  Reconciliation of generally accepted accounting principles

The Company prepares its financial statements in accordance with accounting
principles generally accepted in Canada ("Canadian GAAP") which as applied in
these financial statements conform in all material respects to those accounting
principles generally accepted in the United States ("U.S. GAAP"), except as
follows:

     a.   Under U.S. GAAP, the liability method is used in accounting for income
          taxes pursuant to Statement of Financial Accounting Standards No. 109
          "Accounting for Income Taxes" (SFAS 109). SFAS 109 requires
          recognition of deferred tax assets and liabilities for the expected
          future tax consequences of events that have been included in the
          financial statements or tax returns. Under this method, deferred tax
          assets and liabilities are determined based on the difference between
          the financial reporting and tax bases of assets and liabilities using
          enacted tax rates that will be in effect for the year in which the
          differences are expected to reverse.

          For reconciliation to U.S. GAAP purposes, a valuation allowance has
          been recognized to offset deferred tax assets totaling approximately
          $1,269,000 arising from temporary differences, tax credits and non-
          capital loss carry forwards, for which realization is uncertain.

     b.   In 1997, the Financial Accounting Standards Board issued Statement of
          Financial Accounting Standards No. 128, Earnings per Share (SFAS 128).
          SFAS 128 replaced the previously reported primary and fully diluted
          earnings per share with basic and dilutive earnings per share. Unlike
          primary earnings per share, basic earnings per share excludes any
          dilutive effects of options, warrants, and escrow shares. Dilutive
          earnings per share are calculated in accordance with the treasury
          stock method and are based on the weighted average number of common
          shares and dilutive common share equivalents outstanding. For purposes
          of reconciling to U.S. GAAP, all earnings per share amounts for all
          periods have been presented, and where necessary, restated to conform
          to the SFAS 128 requirements.

     c.   The Company operates primarily in one business segment with
          substantially all of its assets and operations in Canada.

     d.   Under US GAAP, stock based compensation to non-employees must be
          recorded at the fair market value of the options granted pursuant to
          Statement of Financial Accounting Standards No. 123 (SFAS 123).  This
          compensation, determined using a Black-Scholes pricing model, is
          expensed over the vesting periods of each option granted. For purposes
          of reconciliation to US GAAP under SFAS 123, the Company would record
          additional compensation expense of $162,000 in respect of options
          granted to non-employees [1997 $nil; 1996 $121,722 ].

     e.   Under U.S. GAAP costs incurred in connection with the reverse
          acquisition in 1996 totaling $155,875, net of cash received from the
          acquisition of $15,028, must be charged to expense.

     f.   Under U.S. GAAP, the excess, if any, of the fair value of the shares
          in escrow over the nominal value paid would be recorded as
          compensation expense upon release from escrow.

The effect of the above on the Company's financial statements is set out below:

<PAGE>


THIS INCENTIVE STOCK OPTION AGREEMENT is made as of the 20th day of April,
2000.

BETWEEN:

            IMMUNE NETWORK RESEARCH LTD., having an office
            ---------------------------
            located at 3650 Wesbrook Mall, Vancouver, BC,
            Canada, V6S 2L2

            (the "Company")

AND:

            ALLEN BAIN, of 2039 MacDonald Street, Vancouver,
            ----------
            BC, Canada, V6K 3Y2

            (the "Optionee")

WHEREAS the Optionee is a director, senior officer, consultant, dependant
contractor or a bona fide employee of the Company or a subsidiary thereof, or an
employee of a company under contract to provide management services to the
Company (the "Management Company") and requires as a condition of holding such
position that the parties enter into this Agreement on the terms and conditions
set forth;

THIS AGREEMENT WITNESSES that in consideration of the covenants and agreements
herein contained, the parties agree as follows:

1.   The Company hereby grants to the Optionee, as an incentive and in
     consideration of his services and not in lieu of salary or any other
     compensation, subject to the terms and conditions hereinafter set forth,
     the irrevocable right and option (the "Option") to purchase from time to
     time up to a total of 380,000 fully paid and non-assessable common shares
     in the capital stock of the Company.

2.   Subject to the provisions of paragraphs 5, 6 and 8 hereof, the Option
     shall be exercisable by the Optionee in whole or in part at any time before
     4:00 p.m. (Vancouver time) on April 19, 2005 (the "Expiry Date") at an
     exercise price of $1.20 per share. The Option is exercisable on a quarterly
     basis as to 25% of the Option at the end of each three month period
     commencing from the date of this Agreement.

3.   In order to exercise the Option, the Optionee shall give written notice
     to the Company of his intention to exercise his Option in whole or in part,
     such notice to be accompanied by bank draft or money order payable to the
     Company for the full amount of the purchase price of the shares then being
     purchased. The Company will issue for the Optionee's collection a share
     certificate registered in the name of the Optionee for the number of shares
     purchased.

4.   The Optionee acknowledges that the shares acquired on exercise of the
     Option will be subject to a four month hold period commencing from the date
     of this Agreement, within which period the shares may not be traded,
     transferred or otherwise disposed of. The certificate issued evidencing the
     shares acquired upon an exercise of the Option will bear the restrictive
     legend prescribed by the Canadian Venture Exchange.

5.   The parties represent that the Optionee is a director, senior officer,

<PAGE>

     consultant, dependant contractor or an employee of the Company or a
     subsidiary thereof or an employee of the Management Company. Subject to the
     provisions of paragraphs 5 and 8, the Option shall terminate at the close
     of business on the date which is 30 calendar days after the Optionee ceases
     to be a director, senior officer, consultant, dependant contractor or an
     employee of the Company or a subsidiary thereof or ceases to be an employee
     of the Management Company and any unexercised portion of the Option may not
     be exercised by the Optionee after such time.

6.   If at any time the Optionee shall be dismissed by the Company or the
     Management Company for cause or if the Company's contract with the
     Management Company or with the Optionee terminates, any unexercised portion
     of the Option shall immediately terminate.

7.   The Optionee shall not, while employed by or otherwise providing services
     to the Company (or a subsidiary thereof) or the Management Company, or at
     any time thereafter, disclose to any person, firm or corporation any
     confidential information concerning the business affairs of the Company,
     whether for his own benefit, or to the detriment, or intended or probable
     detriment, of the Company. The provisions of this paragraph shall be in
     addition to any other confidentiality agreement the Optionee has entered
     into with the Company (or a subsidiary thereof) or the Management Company.

8.   If the Optionee dies while any Options are exercisable, the Option may
     then be exercised by his legal heirs or personal representatives, to the
     same extent as if the Optionee was alive and a director, senior officer,
     consultant, dependant contractor or an employee of the Company or a
     subsidiary thereof or of the Management Company, on or before the earlier
     of a period of 12 months after the Optionee's death or the Expiry Date but
     only for such shares as the Optionee was entitled to as at the date of the
     death of the Optionee.

9.   Subject to paragraph 8, the Option shall be non-transferable and non-
     assignable.

10.  The Optionee covenants and agrees that he will complete, sign and deliver
     the documents prescribed by the policies of the Canadian Venture Exchange.

11.  The granting and exercise of the Option by the Optionee are subject to
     the required approvals of:

     (a) the British Columbia Securities Commission or, if the Company is listed
         thereon, the Canadian Venture Exchange;
     (b) any other regulatory authority having jurisdiction; and
     (c) if the Optionee is a consultant of the Company, then by the
         shareholders of the Company,

     provided, however, that in the event that such approvals are not obtained
     within 12 months of the date of this Agreement, then this Agreement shall
     from that date be null and void and of no further force and effect. For the
     purposes of this Agreement, the term "insider" shall have the meaning
     ascribed to it in the Securities Act (British Columbia).

12.  Any amendment of the Option shall be subject to such approval as may be
     required by the policies of the Canadian Venture Exchange (if the Company's
     shares are listed thereon at the time of such amendment) in effect at the
     time of the amendment. The Optionee acknowledges that it is a Canadian

<PAGE>

     Venture Exchange requirement that a reduction in the exercise price of the
     Option requires disinterested shareholder approval (as defined in the
     Canadian Venture Exchange Corporate Finance Manual) if the Optionee is an
     insider of the Company at the time of the amendment.

13.  In the event of any subdivision, consolidation or other change in the share
     capital of the Company while any portion of the Option is outstanding, the
     number of shares under Option to the Optionee and the exercise price
     thereof shall be deemed adjusted in accordance with such subdivision,
     consolidation or other change in the share capital of the Company.

14.  In the event that the Company shall amalgamate, consolidate with, or merge
     into another corporation, the Optionee will thereafter receive, upon
     exercise of the Option, the securities or property to which a holder of the
     number of shares then deliverable upon the exercise of the Option would
     have been entitled upon such amalgamation, consolidation or merger and the
     Company will take steps in connection with such amalgamation, consolidation
     or merger as may be necessary to ensure that the provisions hereof shall
     thereafter be applicable, as near as reasonably may be, in relation to any
     securities or property thereafter deliverable upon the exercise of the
     Option. A sale of all or substantially all of the assets of the Company for
     a consideration (apart from the assumption of obligations), a substantial
     portion of which consists of securities, shall be deemed a consolidation,
     amalgamation or merger for the purposes of this Agreement.

15.  This Agreement shall enure to the benefit of and be binding upon the
     parties and upon the successors or assigns of the Company and the
     executors, administrators, and the Optionee's legal personal
     representatives.

16.  The Optionee acknowledges that neither the Option nor the shares issuable
     upon exercise of the Option have been registered under the United States
     Securities Act of 1933, as amended (the "1933 Act") and may not be offered
     or resold in the United States unless registered under the 1933 Act and the
     securities laws of all applicable states of the United States or an
     exemption from such registration requirements is available. The
     certificates representing any shares issued upon exercise of the Option may
     contain a restrictive legend substantially in the following form:

        "The securities represented by this certificate have not been registered
        under the United States Securities Act of 1933, as amended (the "1933
        Act"), and may not be offered or sold in the United States or to U.S.
        Persons or for the account or benefit of a U.S. Person or exercised by
        or on behalf of a U.S. Person, unless registered under the 1933 Act or
        unless an exemption from such registration is available."

17.  This Agreement shall be exclusively governed by the laws of British
     Columbia and the laws of Canada applicable therein and is subject to the
     exclusive jurisdiction of the courts of the said Province.

18.  This Agreement may be signed by the parties in counterparts, both of
     which together shall form one and the same instrument and each of which so
     signed shall be deemed to be an original. This Agreement may be delivered
     by fax.

IN WITNESS WHEREOF the parties have executed this Agreement the day and year
first above written notwithstanding its actual date of execution.

            ---------------------------
            located at 3650 Wesbrook Mall, Vancouver, BC,

            (the "Company")

AND:

            ROBERT GAYTON, of 5145 Ashfield Road, West
            -------------
            Vancouver, BC, Canada, V7W 2X4

            (the "Optionee")

WHEREAS the Optionee is a director, senior officer, consultant, dependant
contractor or a bona fide employee of the Company or a subsidiary thereof, or an
employee of a company under contract to provide management services to the
Company (the "Management Company") and requires as a condition of holding such
position that the parties enter into this Agreement on the terms and conditions
set forth;

THIS AGREEMENT WITNESSES that in consideration of the covenants and agreements
herein contained, the parties agree as follows:

1.   The Company hereby grants to the Optionee, as an incentive and in
     consideration of his services and not in lieu of salary or any other
     compensation, subject to the terms and conditions hereinafter set forth,
     the irrevocable right and option (the "Option") to purchase from time to
     time up to a total of 380,000 fully paid and non-assessable common shares
     in the capital stock of the Company.

2.   Subject to the provisions of paragraphs 5, 6 and 8 hereof, the Option
     shall be exercisable by the Optionee in whole or in part at any time before
     4:00 p.m. (Vancouver time) on April 19, 2005 (the "Expiry Date") at an
     exercise price of $1.20 per share. The Option is exercisable on a quarterly
     basis as to 25% of the Option at the end of each three month period
     commencing from the date of this Agreement.

3.   In order to exercise the Option, the Optionee shall give written notice
     to the Company of his intention to exercise his Option in whole or in part,
     such notice to be accompanied by bank draft or money order payable to the
     Company for the full amount of the purchase price of the shares then being
     purchased. The Company will issue for the Optionee's collection a share
     certificate registered in the name of the Optionee for the number of shares
     purchased.

4.   The Optionee acknowledges that the shares acquired on exercise of the
     Option will be subject to a four month hold period commencing from the date
     of this Agreement, within which period the shares may not be traded,
     transferred or otherwise disposed of. The certificate issued evidencing the
     shares acquired upon an exercise of the Option will bear the restrictive
     legend prescribed by the Canadian Venture Exchange.

5.   The parties represent that the Optionee is a director, senior officer,

<PAGE>

     consultant, dependant contractor or an employee of the Company or a
     subsidiary thereof or an employee of the Management Company. Subject to the
     provisions of paragraphs 5 and 8, the Option shall terminate at the close
     of business on the date which is 30 calendar days after the Optionee ceases
     to be a director, senior officer, consultant, dependant contractor or an
     employee of the Company or a subsidiary thereof or ceases to be an employee
     of the Management Company and any unexercised portion of the Option may not
     be exercised by the Optionee after such time.

6.   If at any time the Optionee shall be dismissed by the Company or the
     Management Company for cause or if the Company's contract with the
     Management Company or with the Optionee terminates, any unexercised portion
     of the Option shall immediately terminate.

7.   The Optionee shall not, while employed by or otherwise providing services
     to the Company (or a subsidiary thereof) or the Management Company, or at
     any time thereafter, disclose to any person, firm or corporation any
     confidential information concerning the business affairs of the Company,
     whether for his own benefit, or to the detriment, or intended or probable
     detriment, of the Company. The provisions of this paragraph shall be in
     addition to any other confidentiality agreement the Optionee has entered
     into with the Company (or a subsidiary thereof) or the Management Company.

8.   If the Optionee dies while any Options are exercisable, the Option may
     then be exercised by his legal heirs or personal representatives, to the
     same extent as if the Optionee was alive and a director, senior officer,
     consultant, dependant contractor or an employee of the Company or a
     subsidiary thereof or of the Management Company, on or before the earlier
     of a period of 12 months after the Optionee's death or the Expiry Date but
     only for such shares as the Optionee was entitled to as at the date of the
     death of the Optionee.

9.   Subject to paragraph 8, the Option shall be non-transferable and non-
     assignable.

10.  The Optionee covenants and agrees that he will complete, sign and deliver
     the documents prescribed by the policies of the Canadian Venture Exchange.

11.  The granting and exercise of the Option by the Optionee are subject to
     the required approvals of:

     (a) the British Columbia Securities Commission or, if the Company is listed
         thereon, the Canadian Venture Exchange;
     (b) any other regulatory authority having jurisdiction; and
     (c) if the Optionee is a consultant of the Company, then by the
         shareholders of the Company,

     provided, however, that in the event that such approvals are not obtained
     within 12 months of the date of this Agreement, then this Agreement shall
     from that date be null and void and of no further force and effect. For the
     purposes of this Agreement, the term "insider" shall have the meaning
     ascribed to it in the Securities Act (British Columbia).

12.  Any amendment of the Option shall be subject to such approval as may be
     required by the policies of the Canadian Venture Exchange (if the Company's
     shares are listed thereon at the time of such amendment) in effect at the
     time of the amendment. The Optionee acknowledges that it is a Canadian

<PAGE>

     Venture Exchange requirement that a reduction in the exercise price of the
     Option requires disinterested shareholder approval (as defined in the
     Canadian Venture Exchange Corporate Finance Manual) if the Optionee is an
     insider of the Company at the time of the amendment.

13.  In the event of any subdivision, consolidation or other change in the share
     capital of the Company while any portion of the Option is outstanding, the
     number of shares under Option to the Optionee and the exercise price
     thereof shall be deemed adjusted in accordance with such subdivision,
     consolidation or other change in the share capital of the Company.

14.  In the event that the Company shall amalgamate, consolidate with, or merge
     into another corporation, the Optionee will thereafter receive, upon
     exercise of the Option, the securities or property to which a holder of the
     number of shares then deliverable upon the exercise of the Option would
     have been entitled upon such amalgamation, consolidation or merger and the
     Company will take steps in connection with such amalgamation, consolidation
     or merger as may be necessary to ensure that the provisions hereof shall
     thereafter be applicable, as near as reasonably may be, in relation to any
     securities or property thereafter deliverable upon the exercise of the
     Option. A sale of all or substantially all of the assets of the Company for
     a consideration (apart from the assumption of obligations), a substantial
     portion of which consists of securities, shall be deemed a consolidation,
     amalgamation or merger for the purposes of this Agreement.

15.  This Agreement shall enure to the benefit of and be binding upon the
     parties and upon the successors or assigns of the Company and the
     executors, administrators, and the Optionee's legal personal
     representatives.

16.  The Optionee acknowledges that neither the Option nor the shares issuable
     upon exercise of the Option have been registered under the United States
     Securities Act of 1933, as amended (the "1933 Act") and may not be offered
     or resold in the United States unless registered under the 1933 Act and the
     securities laws of all applicable states of the United States or an
     exemption from such registration requirements is available. The
     certificates representing any shares issued upon exercise of the Option may
     contain a restrictive legend substantially in the following form:

        "The securities represented by this certificate have not been registered
        under the United States Securities Act of 1933, as amended (the "1933
        Act"), and may not be offered or sold in the United States or to U.S.
        Persons or for the account or benefit of a U.S. Person or exercised by
        or on behalf of a U.S. Person, unless registered under the 1933 Act or
        unless an exemption from such registration is available."

17.  This Agreement shall be exclusively governed by the laws of British
     Columbia and the laws of Canada applicable therein and is subject to the
     exclusive jurisdiction of the courts of the said Province.

18.  This Agreement may be signed by the parties in counterparts, both of
     which together shall form one and the same instrument and each of which so
     signed shall be deemed to be an original. This Agreement may be delivered
     by fax.

IN WITNESS WHEREOF the parties have executed this Agreement the day and year
first above written notwithstanding its actual date of execution.

     provided, however, that in the event that such approvals are not obtained
     within 12 months of the date of this Agreement, then this Agreement shall
     from that date be null and void and of no further force and effect. For the
     purposes of this Agreement, the term "insider" shall have the meaning
     ascribed to it in the Securities Act (British Columbia).

12.  Any amendment of the Option shall be subject to such approval as may be
     required by the policies of the Canadian Venture Exchange (if the Company's
     shares are listed thereon at the time of such amendment) in effect at the
     time of the amendment. The Optionee acknowledges that it is a Canadian

<PAGE>

     Venture Exchange requirement that a reduction in the exercise price of the
     Option requires disinterested shareholder approval (as defined in the
     Canadian Venture Exchange Corporate Finance Manual) if the Optionee is an
     insider of the Company at the time of the amendment.

13.  In the event of any subdivision, consolidation or other change in the share
     capital of the Company while any portion of the Option is outstanding, the
     number of shares under Option to the Optionee and the exercise price
     thereof shall be deemed adjusted in accordance with such subdivision,
     consolidation or other change in the share capital of the Company.

14.  In the event that the Company shall amalgamate, consolidate with, or merge
     into another corporation, the Optionee will thereafter receive, upon
     exercise of the Option, the securities or property to which a holder of the
     number of shares then deliverable upon the exercise of the Option would
     have been entitled upon such amalgamation, consolidation or merger and the
     Company will take steps in connection with such amalgamation, consolidation
     or merger as may be necessary to ensure that the provisions hereof shall
     thereafter be applicable, as near as reasonably may be, in relation to any
     securities or property thereafter deliverable upon the exercise of the
     Option. A sale of all or substantially all of the assets of the Company for
     a consideration (apart from the assumption of obligations), a substantial
     portion of which consists of securities, shall be deemed a consolidation,
     amalgamation or merger for the purposes of this Agreement.

15.  This Agreement shall enure to the benefit of and be binding upon the
     parties and upon the successors or assigns of the Company and the
     executors, administrators, and the Optionee's legal personal
     representatives.

16.  The Optionee acknowledges that neither the Option nor the shares issuable
     upon exercise of the Option have been registered under the United States
     Securities Act of 1933, as amended (the "1933 Act") and may not be offered
     or resold in the United States unless registered under the 1933 Act and the
     securities laws of all applicable states of the United States or an
     exemption from such registration requirements is available. The
     certificates representing any shares issued upon exercise of the Option may
     contain a restrictive legend substantially in the following form:

        "The securities represented by this certificate have not been registered
        under the United States Securities Act of 1933, as amended (the "1933
        Act"), and may not be offered or sold in the United States or to U.S.
        Persons or for the account or benefit of a U.S. Person or exercised by
        or on behalf of a U.S. Person, unless registered under the 1933 Act or
        unless an exemption from such registration is available."

17.  This Agreement shall be exclusively governed by the laws of British
     Columbia and the laws of Canada applicable therein and is subject to the
     exclusive jurisdiction of the courts of the said Province.

18.  This Agreement may be signed by the parties in counterparts, both of
     which together shall form one and the same instrument and each of which so
     signed shall be deemed to be an original. This Agreement may be delivered
     by fax.

IN WITNESS WHEREOF the parties have executed this Agreement the day and year
first above written notwithstanding its actual date of execution.

BETWEEN:

            IMMUNE NETWORK RESEARCH LTD., having an office
            ---------------------------
            located at 3650 Wesbrook Mall, Vancouver, BC,
            Canada, V6S 2L2

            (the "Company")

AND:

            RON PATON, of 802-1250 Quayside Drive, New
            ---------
            Westminister, BC, Canada, V3M 6E2

            (the "Optionee")

WHEREAS the Optionee is a director, senior officer, consultant, dependant
contractor or a bona fide employee of the Company or a subsidiary thereof, or an
employee of a company under contract to provide management services to the
Company (the "Management Company") and requires as a condition of holding such
position that the parties enter into this Agreement on the terms and conditions
set forth;

THIS AGREEMENT WITNESSES that in consideration of the covenants and agreements
herein contained, the parties agree as follows:

1.   The Company hereby grants to the Optionee, as an incentive and in
     consideration of his services and not in lieu of salary or any other
     compensation, subject to the terms and conditions hereinafter set forth,
     the irrevocable right and option (the "Option") to purchase from time to
     time up to a total of 380,000 fully paid and non-assessable common shares
     in the capital stock of the Company.

2.   Subject to the provisions of paragraphs 5, 6 and 8 hereof, the Option
     shall be exercisable by the Optionee in whole or in part at any time before
     4:00 p.m. (Vancouver time) on April 19, 2005 (the "Expiry Date") at an
     exercise price of $1.20 per share. The Option is exercisable on a quarterly
     basis as to 25% of the Option at the end of each three month period
     commencing from the date of this Agreement.

3.   In order to exercise the Option, the Optionee shall give written notice
     to the Company of his intention to exercise his Option in whole or in part,
     such notice to be accompanied by bank draft or money order payable to the
     Company for the full amount of the purchase price of the shares then being
     purchased. The Company will issue for the Optionee's collection a share
     certificate registered in the name of the Optionee for the number of shares
     purchased.

4.   The Optionee acknowledges that the shares acquired on exercise of the
     Option will be subject to a four month hold period commencing from the date
     of this Agreement, within which period the shares may not be traded,
     transferred or otherwise disposed of. The certificate issued evidencing the
     shares acquired upon an exercise of the Option will bear the restrictive
     legend prescribed by the Canadian Venture Exchange.

5.   The parties represent that the Optionee is a director, senior officer,

<PAGE>

     consultant, dependant contractor or an employee of the Company or a
     subsidiary thereof or an employee of the Management Company. Subject to the
     provisions of paragraphs 5 and 8, the Option shall terminate at the close
     of business on the date which is 30 calendar days after the Optionee ceases
     to be a director, senior officer, consultant, dependant contractor or an
     employee of the Company or a subsidiary thereof or ceases to be an employee
     of the Management Company and any unexercised portion of the Option may not
     be exercised by the Optionee after such time.

6.   If at any time the Optionee shall be dismissed by the Company or the
     Management Company for cause or if the Company's contract with the
     Management Company or with the Optionee terminates, any unexercised portion
     of the Option shall immediately terminate.

7.   The Optionee shall not, while employed by or otherwise providing services
     to the Company (or a subsidiary thereof) or the Management Company, or at
     any time thereafter, disclose to any person, firm or corporation any
     confidential information concerning the business affairs of the Company,
     whether for his own benefit, or to the detriment, or intended or probable
     detriment, of the Company. The provisions of this paragraph shall be in
     addition to any other confidentiality agreement the Optionee has entered
     into with the Company (or a subsidiary thereof) or the Management Company.

8.   If the Optionee dies while any Options are exercisable, the Option may
     then be exercised by his legal heirs or personal representatives, to the
     same extent as if the Optionee was alive and a director, senior officer,
     consultant, dependant contractor or an employee of the Company or a
     subsidiary thereof or of the Management Company, on or before the earlier
     of a period of 12 months after the Optionee's death or the Expiry Date but
     only for such shares as the Optionee was entitled to as at the date of the
     death of the Optionee.

9.   Subject to paragraph 8, the Option shall be non-transferable and non-
     assignable.

10.  The Optionee covenants and agrees that he will complete, sign and deliver
     the documents prescribed by the policies of the Canadian Venture Exchange.

11.  The granting and exercise of the Option by the Optionee are subject to
     the required approvals of:

     (a) the British Columbia Securities Commission or, if the Company is listed
         thereon, the Canadian Venture Exchange;
     (b) any other regulatory authority having jurisdiction; and
     (c) if the Optionee is a consultant of the Company, then by the
         shareholders of the Company,

     provided, however, that in the event that such approvals are not obtained
     within 12 months of the date of this Agreement, then this Agreement shall
     from that date be null and void and of no further force and effect. For the
     purposes of this Agreement, the term "insider" shall have the meaning
     ascribed to it in the Securities Act (British Columbia).

12.  Any amendment of the Option shall be subject to such approval as may be
     required by the policies of the Canadian Venture Exchange (if the Company's
     shares are listed thereon at the time of such amendment) in effect at the
     time of the amendment. The Optionee acknowledges that it is a Canadian

<PAGE>

     Venture Exchange requirement that a reduction in the exercise price of the
     Option requires disinterested shareholder approval (as defined in the
     Canadian Venture Exchange Corporate Finance Manual) if the Optionee is an
     insider of the Company at the time of the amendment.

13.  In the event of any subdivision, consolidation or other change in the share
     capital of the Company while any portion of the Option is outstanding, the
     number of shares under Option to the Optionee and the exercise price
     thereof shall be deemed adjusted in accordance with such subdivision,
     consolidation or other change in the share capital of the Company.

14.  In the event that the Company shall amalgamate, consolidate with, or merge
     into another corporation, the Optionee will thereafter receive, upon
     exercise of the Option, the securities or property to which a holder of the
     number of shares then deliverable upon the exercise of the Option would
     have been entitled upon such amalgamation, consolidation or merger and the
     Company will take steps in connection with such amalgamation, consolidation
     or merger as may be necessary to ensure that the provisions hereof shall
     thereafter be applicable, as near as reasonably may be, in relation to any
     securities or property thereafter deliverable upon the exercise of the
     Option. A sale of all or substantially all of the assets of the Company for
     a consideration (apart from the assumption of obligations), a substantial
     portion of which consists of securities, shall be deemed a consolidation,
     amalgamation or merger for the purposes of this Agreement.

15.  This Agreement shall enure to the benefit of and be binding upon the
     parties and upon the successors or assigns of the Company and the
     executors, administrators, and the Optionee's legal personal
     representatives.

16.  The Optionee acknowledges that neither the Option nor the shares issuable
     upon exercise of the Option have been registered under the United States
     Securities Act of 1933, as amended (the "1933 Act") and may not be offered
     or resold in the United States unless registered under the 1933 Act and the
     securities laws of all applicable states of the United States or an
     exemption from such registration requirements is available. The
     certificates representing any shares issued upon exercise of the Option may
     contain a restrictive legend substantially in the following form:

        "The securities represented by this certificate have not been registered
        under the United States Securities Act of 1933, as amended (the "1933
        Act"), and may not be offered or sold in the United States or to U.S.
        Persons or for the account or benefit of a U.S. Person or exercised by
        or on behalf of a U.S. Person, unless registered under the 1933 Act or
        unless an exemption from such registration is available."

17.  This Agreement shall be exclusively governed by the laws of British
     Columbia and the laws of Canada applicable therein and is subject to the
     exclusive jurisdiction of the courts of the said Province.

18.  This Agreement may be signed by the parties in counterparts, both of
     which together shall form one and the same instrument and each of which so
     signed shall be deemed to be an original. This Agreement may be delivered
     by fax.

IN WITNESS WHEREOF the parties have executed this Agreement the day and year
first above written notwithstanding its actual date of execution.

               equal to 30% of the remaining contract payments would be due to
               CroMedica.

               A termination by INR for any other reason, except by reason of a
               breach of a material term of this agreement by CroMedica, will
               result in a termination fee equal to 10% of the remaining
               contract payment becoming due to CroMedica.

          Termination of this Agreement by either party shall not affect the
          rights and obligations of the parties accrued prior to the effective
          date of termination.  The rights and duties under Articles III, IV,
          VII, VIII, IX, X, XI, XII, XIV, XVI, XVII, XVIII, XIX, XX and XXI
          shall survive the termination or expiration of this Agreement.

VIII.     CONFIDENTIAL INFORMATION
          ------------------------

          A. Definition
             ----------

          For purposes of this Agreement, "Confidential Information" means any
          knowledge or information that is (1) acquired by CroMedica from INR
          prior to or during the course of the Investigation, or (2) prepared,
          developed or generated by CroMedica during the course of the
          Investigation; provided, however, that "Confidential Information" does
          not include knowledge or information that CroMedica can demonstrate by
          written records was known by it prior to the receipt of such knowledge
          or information from INR, or that is publicly disclosed by INR either
          prior to or subsequent to receipt of the knowledge or information by
          CroMedica.


          B. Non-Disclosure
             --------------

          CroMedica (1) shall not publish, disseminate, or otherwise disclose to
          any third party (except as may be required by this Agreement or by
          law) any Confidential Information without the prior written consent of
          INR; (2) shall use the same care and discretion in maintaining the
          confidentiality of the Confidential Information that CroMedica uses
          with similar information that it considers confidential; provided that
          such care and discretion shall not be less than the standard of care

<PAGE>
Page 5

          and discretion that would be employed by a prudent person under
          similar circumstances; (3) shall restrict the dissemination of the
          Confidential Information within its own organization to persons who
          have a need to know and have agreed to abide by the confidentiality
          provisions of this Agreement; and (4) shall not, without the prior
          written consent of INR, make any use whatever of the Confidential
          Information except for the purpose of conducting the Investigation.
          In the event CroMedica is required by applicable law to disclose
          Confidential Information to a proper authority, CroMedica shall
          first notify INR, and CroMedica and INR shall then attempt in good
          faith to agree upon a mutually satisfactory way to disclose such
          Confidential Information as necessary for this limited purpose.
          CroMedica shall ensure that its employees, officer, directors,

     become due and payable by monthly instalments, each in the amount of U.S.
     $83,333.33, payable on the 1st day of each month from and including October
     1, 2001 to and including August 1, 2003, except that:

     (a) if the Option A pricing and payment terms described in Exhibit "C" of
         the Services Agreement applies, then the payment due and payable on
         June 1, 2002 shall be US$166,666.66 and not US$83,333.33; and

3.   Interest. Interest shall be payable on the 1st day of each and every

     interest and any other moneys due and payable hereunder, both before and
     after maturity, default or judgment, at the rate of interest per annum (the
     "Interest Rate") which is five percent (5%) greater than the Prime Rate for
     the applicable period calculated and compounded monthly, computed from the
     respective dates that the principal becomes owing in accordance with
     section 1 of this Debenture until payment in full of all moneys owing
     hereunder. CroMedica shall notify the Company at least five (5) days prior
     to each interest payment date of the Prime Rate for the applicable period

     days' written notice to CroMedica at a price equal to the principal amount
     being redeemed, together in each case with accrued and unpaid interest on
     such principal amount to the date fixed for redemption and, in the case of
     redemption in whole, all other moneys owing hereunder for services
     performed or to be performed by CroMedica in accordance with the Services
     Agreement. Except as described in this section 4, the Company shall have no
     other right of prepayment.

5.   Partial Payments. In case less than the total principal amount of this
     ----------------
     Debenture is redeemed at any time, the principal amount so redeemed shall
     be credited against the principal payable hereunder in inverse order of
     maturity.

6.   Security. As security for the payment of the principal, interest and all
     --------
     other moneys from time to time payable under this Debenture, and the

     interests constituted hereby and by any supplemental security granted to

3.     Performance of Covenants by CroMedica. If the Company shall fail to
       -------------------------------------
       perform any covenant on its part herein contained, CroMedica may in its
       absolute discretion perform any such covenant capable of being performed
       by it. If any such covenant requires the payment of money or if the
       Mortgaged Premises or any part thereof shall become subject to any charge
       ranking in priority to the lien hereof, CroMedica may make such payment
       and/or pay or discharge such charge, but shall be under no obligation to
       do so. All sums so paid by CroMedica, together with interest at the

Page 8

       Interest Rate, shall be payable on demand and shall constitute a charge
       upon the Mortgaged Premises. No such performance or payment shall relieve
       the Company from any default hereunder or any consequences of such
       default.

4.     No Merger or Novation. The taking of any judgment or the exercise of any
       ---------------------
       power of seizure or sale shall not operate to extinguish the liability of
       the Company to perform its obligations hereunder or to pay the moneys
       hereby secured, shall not operate as a merger of any covenant herein
       contained or affect the right of CroMedica to interest at the Interest
       Rate in effect from time to time hereunder, and the acceptance of any
       payment or other security shall not constitute or create any novation.
       The execution and delivery of this Debenture or of any instruments or
       documents supplemental hereto shall not operate as a merger of any
       representation, warranty, term, condition or other provision contained
       in any other obligation or indebtedness of the Company to CroMedica.

5.     Events of Default. The whole of the principal balance remaining unpaid
       -----------------
       together with interest and all other moneys secured by this Debenture
       shall, at the option of CroMedica, become immediately due and payable and
       the security hereby created shall become enforceable in each of the
       following events (each event being herein called an "event of default"):

       (a) if the Company defaults in payment of the principal of or interest on

           seeking to adjudicate it a bankrupt or insolvent, or (ii) seeking
           liquidation, dissolution, winding up, reorganization, arrangement,
           protection, relief or composition of it or any of its property or

           to bankruptcy, insolvency, reorganization or compromise of debts or
           other similar laws (including, without limitation, any application
           under the Companies' Creditors Arrangement Act or any reorganization,

                 (including, without limitation, any reorganization, arrangement

                 and assets, including the Mortgaged Premises or any part
                 thereof;

       (f) if an encumbrancer or secured creditor shall appoint a receiver or

           property of the Company, or a distress or like process is levied upon
           any of such property;

       (g) if the Company takes any corporate proceedings for its dissolution,

entitle the holder thereof, upon exercise at any time during the Exercise Period
and payment to the Issuer of the Warrant Share Purchase Price by way of
certified cheque or bank draft, to be issued, subject to adjustment in
accordance with Article 7, one Warrant Share.

2.3  Fractional Unit Warrants

Notwithstanding any adjustments provided for in this Indenture, the Company
shall not be required upon the exercise of any Unit Warrants to issue fractional
Warrant Shares in satisfaction of its obligations hereunder.  Where a fractional
Warrant Share, but for this  section 2.3, would have been issued upon exercise
of a Unit Warrant, in lieu thereof  there shall be paid to the holder an amount
equal (rounded to the nearest $0.01) to the product obtained by multiplying such
fractional share interest by the Current Market Price at the date of delivery of
each respective Warrant Certificate, which payment shall be made within ten
business days of such delivery.  Notwithstanding the foregoing, the Company
shall not be required to make any payment, calculated as aforesaid, that is less
than $5.00.

2.4  Form of Warrant Certificates

Unit Warrants will be issued in registered form only and will be evidenced only
by Warrant Certificates, which will be substantially in the form attached as
Schedule "A" or in such other form as may be approved by the Company, the Agent
and the Trustee, will be dated as of the Exercise Date (as defined in the

<PAGE>
Page 7

Special Warrant Indenture), regardless of their actual dates of issue, and will
bear such distinguishing letters and numbers as the Company will prescribe with
the approval of the Trustee and will bear such legends as may be required under
the Applicable Securities Laws and shall be issuable in any denomination
excluding fractions.

2.5  Delivery of Warrant Certificates

The Warrant Certificates will be delivered to the Warrantholders in accordance
with the provisions of the Special Warrant Indenture.

2.6  Issue in Substitution of Unit Warrants

If any of the Warrant Certificates becomes mutilated, lost, destroyed or stolen
(the "Old Certificate"), the Company, subject to applicable law and to section
2.7, will issue and the Trustee will certify and deliver a new Warrant
Certificate of like date and tenor as the Old Certificate, upon surrender of, in
place of and upon cancellation of the mutilated Old Certificate or in
substitution for the lost, destroyed or stolen Old Certificate, and the
substituted Warrant Certificate will be in a form approved by the Trustee and
will be entitled to the benefit hereof and rank equally in accordance with its
terms with all other Warrant Certificates issued or to be issued under this
Indenture.

2.7  Conditions for Replacement of Unit Warrants

The applicant for the issue of a new Warrant Certificate pursuant to section 2.6
will bear the cost of the issue thereof and in case of loss, destruction or
theft will, as a condition precedent to the issue thereof furnish to the Company
and to the Trustee such evidence of ownership and of the loss, destruction or
theft of the Warrant Certificate so lost, destroyed or stolen as will be
satisfactory to the Company and to the Trustee in their discretion and the
applicant may also be required to furnish an indemnity and surety bond or such
security in amount and form satisfactory to them in their discretion, and will
pay the reasonable charges of the Company and the Trustee in connection with the
issue of the new Warrant Certificate.

2.8  Warrantholder not a Shareholder

Nothing in this Indenture or in the holding of a Unit Warrant evidenced by a
Warrant Certificate, or otherwise, will be construed as conferring upon a
Warrantholder any right or interest whatsoever as a shareholder, including but
not limited to the right to vote at, to receive notice of, or to attend meetings
of shareholders or any other proceedings of the Company or the right to receive
any dividend and other distribution.

2.9  Unit Warrants to Rank Pari Passu

Each Unit Warrant will rank pari passu with all other Unit Warrants, whatever
may be the actual date of issue.

2.10 Signing of Unit Warrants

The Warrant Certificates will be signed by any one of the directors or officers
of the Company and need not be under the seal of the Company.  The signatures of
any of these directors or officers may be mechanically reproduced in facsimile

<PAGE>
Page 8

and Warrant Certificates bearing those facsimile signatures will be binding upon
the Company as if they had been manually signed by the directors or officers.
Notwithstanding that any of the persons whose manual or facsimile signature
appears on any Warrant Certificate as a director or officer may no longer hold
office at the date of the Warrant Certificate or at the date of certification or
delivery thereof, any Warrant Certificate signed as aforesaid will, subject to
section 2.11, be valid and binding upon the Company.

2.11 Certification by the Trustee

No Warrant Certificate will be issued or, if issued, will be valid for any
purpose or entitle the Holder to the benefit hereof until it has been certified
by manual signature by or on behalf of the Trustee in the form of the
certificate set out in Schedule "A" hereto, and the certification by the Trustee
upon any Warrant Certificate will be conclusive evidence as against the Company
that the Warrant Certificate so certified has been duly issued under this
Indenture and that the Holder is entitled to the benefit of this Indenture.

2.12 Certification Not a Representation or Warranty

The certification of the Trustee on Warrant Certificates issued under this
Indenture will not be construed as a representation or warranty by the Trustee
as to the validity of this Indenture or of the Warrant Certificates (except the
due certification thereof) and the Trustee will in no respect be liable or
answerable for the use made of the Unit Warrants or any of them or of the
consideration therefor, except as otherwise specified in this Indenture.

                                    ARTICLE 3
                     EXCHANGE AND OWNERSHIP OF UNIT WARRANTS

3.1  Exchange of Warrant Certificates

Any Warrant Certificate representing a certain number of Unit Warrants may, upon
compliance with the reasonable requirements of the Trustee, be exchanged for one
or more Warrant Certificates representing an equal aggregate number of Unit
Warrants.

3.2  Place for Exchange of Warrant Certificates

Unit Warrants may be exchanged only at the principal transfer office of the
Trustee in the city of Vancouver, Canada or at any other place that is
designated by the Company with the Trustee's approval.  Any Unit  Warrants
tendered for exchange will be surrendered to the Trustee and cancelled. The
Company will sign all Warrant Certificates necessary to carry out exchanges as
aforesaid and those Warrant Certificates will be certified by or on behalf of
the Trustee.

3.3  Charges for Exchange

For each Warrant Certificate exchanged, the Trustee, except as otherwise herein
provided, will charge if required by the Company a reasonable sum for each new
Warrant Certificate issued. The party requesting the exchange, as a condition
precedent to such exchange, will pay such charges and will pay or reimburse the
Trustee or the Company for all exigible transfer taxes or governmental or other
similar transfer charges required to be paid in connection with such exchange.

<PAGE>
Page 9

3.4  Ownership of Unit Warrants

The Company and the Trustee and their respective agents may deem and treat the
holder of any Unit Warrant as the absolute owner of that Unit Warrant for all
purposes, and the Company and the Trustee and their respective agents will not
be affected by any notice or knowledge to the contrary except where so required
by court order or by statute, concerning which the Company and the Trustee shall
be entitled to rely upon advice from legal counsel.  Subject to the provisions
of this Indenture and applicable law, the holder of any Unit Warrant will be
entitled to the rights evidenced by that Unit Warrant free from all equities or
rights of set-off or counterclaim between the Company and the original or any
intermediate holder thereof and all persons may act accordingly and the receipt
from any Holder for the Warrant Shares or monies obtainable pursuant thereto
will be a good discharge to the Company and the Trustee for the same and neither
the Company nor the Trustee will be bound to inquire into the title of any
Holder except where so required by court order or by statute, concerning which
the Company and the Trustee shall be entitled to rely upon advice from legal
counsel.

                                    ARTICLE 4
                         REGISTRAR AND TRANSFER AGENCIES

4.1  Appointment  of  Trustee  as  Registrar

The Company hereby appoints the Trustee as registrar of the Unit Warrants. The
Company may hereafter with the consent of the Trustee, appoint one or more other
additional registrars of the Unit Warrants.

4.2  Register

The Trustee shall maintain a register, at its principal transfer office in the
city of Vancouver, in which will be entered the names and addresses of the
Warrantholders and other particulars of the Unit Warrants held by each of them
respectively and of all transfers of Unit Warrants permitted by this Indenture.

4.3  Register to be Open for Inspection

The register referred to in section 4.2 will at all reasonable times be open for
inspection by the Company by the Trustee and by any Warrantholder. The register
required to be kept at the city of Vancouver will not be closed at any time.

4.4  List of Warrantholders

The Trustee will, when requested so to do by the Company, furnish the Company
with a list of names and addresses of the Warrantholders showing the number of
Unit Warrants held by each Warrantholder.

4.5  Obligations of Trustee

Except as required by law, neither the Trustee nor any other registrar nor the
Company will be charged with notice of or be bound to see to the execution of
any trust, whether express, implied or constructive, in respect of any Unit
Warrant.

                                    ARTICLE 5
                    TRANSFER OF SPECIAL WARRANT CERTIFICATES

5.1  Transfer of Warrant Certificates

Subject to compliance with all applicable securities laws and requirements of
regulatory authorities, including without limitation, any undertaking required
to be given to the Exchange by the transferor and transferee, the holder of a
Unit Warrant may at any time and from time to time have the Unit Warrants
transferred by the Trustee in accordance with the conditions herein and such
reasonable requirements as the Trustee may prescribe.  Any such transfer shall
be duly noted in the register of Unit Warrants maintained by the Trustee.  Upon
compliance with the foregoing requirements, the Trustee shall issue to the
transferee a Warrant Certificate representing the Unit Warrants transferred.
Compliance with all applicable securities laws and requirements of regulatory
authorities shall be the Holder's responsibility and not that of the Trustee.

5.2  Validity of Transfer

No transfer of Unit Warrants will be valid unless made by the Holder or the
Holder's executors or administrators or other legal representatives or the
Holder's attorney duly appointed by an instrument in writing in form and
executed in a manner satisfactory to the registrar, and upon compliance with
such requirements as the registrar may prescribe.

                                    ARTICLE 6
                            EXERCISE OF UNIT WARRANTS

6.1  Exercise During Exercise Period

The holder of a Warrant Certificate may exercise the Unit Warrants represented
by the Warrant Certificate at any time and from time to time in whole or in part
during the Exercise Period. Any such exercise will be subject to the Holder
providing such assurances and executing such documents as may, in the reasonable
opinion of the Company or the Trustee, be required to ensure compliance with
Applicable Securities Laws.

6.2  Method of Exercise of Unit Warrants

A Warrantholder may, during the Exercise Period, exercise the right under a Unit
Warrant to acquire a Warrant Share by surrendering to the Trustee at its
principal transfer office in the city of Vancouver or at any other place or
places that may be designated by the Company with the approval of the Trustee, a
certificate or certificates representing one whole Unit Warrant for each whole
Unit Warrant exercised, together with the full Warrant Share Purchase Price
payable and a fully completed and duly executed exercise form in the form
attached to the Unit Warrant Certificate.

6.3  Surrender of Unit Warrants

The Unit Warrants will only be deemed to have been surrendered upon personal
delivery of the applicable Warrant Certificate(s) and accompanying documents to,
or if sent by mail or other means of transmission, upon actual receipt thereof
by the Trustee.

<PAGE>
Page 11

6.4  Completion and Execution of Exercise Form

Any exercise form referred to in section 6.3 will be signed by the Warrantholder
or the Warrantholder's executors or administrators, successors or other legal
representatives or an attorney of the Warrantholder duly appointed by an
instrument in writing satisfactory to the Trustee. The exercise form attached to
the Warrant Certificate will be completed to specify the number of Unit Warrants
being exercised and the address to which the Warrant Share Certificates should
be delivered if different from that appearing on the Warrant Certificate
surrendered.  If any of the Warrant Shares to be acquired are to be issued to a
person or persons other than the Warrantholder, the Warrantholder will pay, as a
condition to the issue and delivery of the certificates evidencing the Warrant
Shares, to the Trustee or to its agent, on behalf of the Company, all exigible
transfer taxes or governmental or other charges required to be paid in respect
of the transfer of the Unit Warrants or Warrant Shares.

6.5  Resale Restriction Legends

If, at the time of exercise of the Unit Warrants, there remain restrictions on
resale under applicable securities legislation on the Warrant Shares acquired,
the Company may, on the advice of counsel, endorse the certificates representing
the Warrant Shares with respect to those restrictions, and prior to the issuance
of any such certificates the Trustee shall consult with the Company to determine
whether such endorsing or legending is required.

6.6  Effect of Exercise of Unit Warrants

Upon exercise of the Unit Warrants and compliance by the Warrantholder with
sections 6.4 and 6.5 subject to sections 6.9, 6.10 and 7.9, the holder of the
Unit Warrants will be entitled to receive, upon payment of the Warrant Share
Purchase Price, one Warrant Share for each whole Unit Warrant exercised, subject
to adjustment as provided in this Indenture, and the Trustee will cause the
holder thereof to be entered forthwith on its register of shareholders as the
holder of the Warrant Shares on the Warrant Exercise Date.

6.7  Delivery of Warrant Share Certificates

Upon the due exercise of the Unit Warrants as described in this Article 6, the
Company will, within five business days after the Warrant Exercise Date, without
charge therefor except as provided in section 6.5, forthwith cause to be mailed
to Holders at such person's address specified in the exercise form, or if not
specified in the exercise form, then at the address recorded in the register of
Unit Warrants, certificates for the appropriate number of Warrant Shares to
which the Holder is entitled.

6.8  No Fractional Warrant Shares

Notwithstanding any adjustments provided for in this Indenture, the Company
shall not be required upon the exercise of the Unit Warrants to issue fractional
Warrant Shares in satisfaction of its obligations hereunder.  Where a fractional
Warrant Share, but for this section 6.9, would have been issued upon the
exercise of a Unit Warrant, in lieu thereof, there shall be paid to the holder
an amount equal (rounded to the nearest $0.01) to the product obtained by
multiplying such fractional share interest by the closing price of the Common
Shares on the Exchange (or if the Common Shares are not then listed thereon on
such other exchange on which the Common Shares are then listed, or, if not
listed on, in the over-the-counter market as designated by the directors) for

<PAGE>
Page 12

the last trading day prior to the Warrant Exercise Date at the date of delivery
of each respective certificate, which payment shall be made within ten business
days of such delivery.  Notwithstanding the foregoing, the Company shall not be
required to make any payment, calculated as aforesaid, that is less than $5.00.

6.9  Expiration of Unit Warrants

The Unit Warrants and the rights thereunder shall terminate and be of no further
effect upon their exercise and all rights under any Unit Warrant which have not
been exercised prior to the expiry of the Exercise Period will cease and
terminate and the Unit Warrant will be void and of no effect.

6.10 Accounting and Recording

The Trustee will promptly notify the Company in writing with respect to Unit
Warrants exercised. The Trustee will, within five business days of each Warrant
Exercise Date, specify the particulars of the Unit Warrants exercised which will
include the names and addresses of the Holders whose Unit Warrants have been
exercised and the Warrant Exercise Date, and will deliver to the Company the
Warrant Share Purchase Price.

6.11 Cancellation of Surrendered Unit Warrants

All Warrant Certificates surrendered to the Trustee in accordance with the
provisions of this Indenture will be cancelled by the Trustee and upon request
therefor of the Company, the Trustee will furnish the Company with written
confirmation of the Warrant Certificates so cancelled and the number of Warrant
Shares which could have been acquired pursuant to each.

                                   ARTICLE 7
                          ADJUSTMENT OF EXCHANGE NUMBER

7.1  Definitions

In this Article the terms "record date" and "effective date" means the close of
business on the relevant date.

7.2  Adjustment of Exchange Number

The Exchange Number (or the number and kind of shares or securities to be
received upon exercise in the case of sections 7.6 and 7.7) will be subject to
adjustment from time to time in the events and in the manner provided in this
Article.

7.3  Share Reorganization

If and whenever at any time from the date of issuance of the Unit Warrants
during the Exercise Period the Company:

(a)  issues to all or substantially all the holders of the Common Shares, by
     way of a stock dividend or other distribution, other than Dividends Paid in
     the Ordinary Course, Common Shares or Convertible Securities; or

<PAGE>
Page 13

(b)  subdivides, redivides or changes its outstanding Common Shares into a
     greater number of shares; or

(c)  combines, consolidates or reduces its outstanding Common Shares into a
     smaller number of shares,

(any of those events being a "Share Reorganization"), the Exchange Number will
be adjusted effective immediately after the record date at which the holders of
Common Shares are determined for the purposes of the Share Reorganization to a
number that is the product of (1) the Exchange Number in effect on the record
date and (2) a fraction:

(i)   the numerator of which will be the number of Common Shares outstanding
      after giving effect to the Share Reorganization; and

(ii)  the denominator of which will be the number of Common Shares
      outstanding on the record date before giving effect to the Share
      Reorganization.

For the purposes of determining the number of Common Shares outstanding at any
particular time for the purpose of this section 7.3 there will be included that
number of Common Shares which would have resulted from the conversion at that
time of all outstanding Convertible Securities (which, for greater certainty,
includes the Warrant Shares issuable upon exercise of the Unit Warrants then
outstanding).

7.4  Rights Offering

If and whenever at any time from the date of issuance of the Unit Warrants
during the Exercise Period the Company issues rights, options or warrants to all
or substantially all the holders of the Common Shares pursuant to which those
holders are entitled to subscribe for, purchase or otherwise acquire Common
Shares or Convertible Securities within a period of 45 days from the date of
issue thereof at a price, or at a conversion price, of less than 95% of the
Current Market Price at the record date for such distribution (any such issuance
being a "Rights Offering" and Common Shares that may be acquired in exercise of
the Rights Offering, or upon conversion of the Convertible Securities offered by
the Rights Offering, being the "Offered Shares"), the Exchange Number will be
adjusted effective immediately after the record date at which holders of Common
Shares are determined for the purposes of the Rights Offering to an Exchange
Number that is the product of (1) the Exchange Number in effect on the record
date and (2) a fraction:

(a)  the numerator of which will be the sum of:

     (i)   the number of Common Shares outstanding on the record date; and

     (ii)  the number of Offered Shares offered pursuant to the Rights Offering
           or the maximum number of Offered Shares into which the Convertible
           Securities so offered pursuant to the Rights Offering may be
           converted, as the case may be;

     and

(b)  the denominator of which will be the sum of:

     (i)   the number of Common Shares outstanding on the record date; and

<PAGE>
Page 14


      (ii)  the number arrived at when either the product of:

            (A) the number of Offered Shares so offered and the price at which
                those shares are offered; or

            (B) the conversion price of the Offered Shares and the maximum
                number of Offered Shares for or into which the Convertible
                Securities so offered pursuant to the Rights Offering may be
                converted, as the case may be, is divided by the Current Market
                Price of the Common Shares on the record date.

Any Offered Shares owned by or held for the account of the Company will be
deemed not to be outstanding for the purpose of any computation; if all the
rights, options or warrants are not so issued or if all rights, options or
warrants are not exercised prior to the expiration thereof, the Exchange Number
will be readjusted to the Exchange Number in effect immediately prior to the
record date, and the Exchange Number will be further adjusted based upon the
number of Offered Shares (or Convertible Securities into Offered Shares)
actually delivered upon the exercise of the rights, options or warrants, as the
case may be, but subject to any other adjustment required hereunder by reason of
any event arising after that record date.

7.5  Special Distribution

If and whenever at any time from the date of issuance of the Unit Warrants
during the Exercise Period the Company will issue or distribute to all or
substantially all the holders of Common Shares:

(a)  shares of any class other than shares distributed to holders of Common
     Shares pursuant to their exercise of options to receive dividends in the
     form of such shares in lieu of Dividends Paid in the Ordinary Course on the
     Common Shares;

(b)  rights, options or warrants other than Unit Warrants and other than rights,
     options or warrants exercisable within 45 days from the date of issue
     thereof at a price, or at a conversion price, of at least 95% of the
     Current Market Price at the record date for such distribution;

(c)  evidences of indebtedness; or

(d)  any other assets including shares of other corporations (excluding cash
     dividends that Warrantholders receive under section 8.3) and that issuance
     or distribution does not constitute a Share Reorganization or a Rights
     Offering,

(any of those events being a "Special Distribution"), the Exchange Number will
be adjusted effective immediately after the record date at which the holders of
Common Shares are determined for purposes of the Special Distribution to an
Exchange Number that is the product of (1) the Exchange Number in effect on the
record date and (2) a fraction:

(i)   the numerator of which will be the product of (A) the sum of the number of
      Common Shares outstanding on the record date plus the number of Common
      Shares which the Warrantholders would be entitled to receive upon exercise
      of all their outstanding Unit Warrants if they were exercised on the
      record date and (B) the Current Market Price thereof on that date; and

<PAGE>
Page 15

(ii)  the denominator of which will be the product of:

      (A) the sum of the number of Common Shares outstanding on the record date
          plus the number of Common Shares which the Special Warrantholders
          would be entitled to receive upon exercise of all their outstanding
          Special Warrants if they were exercised on the record date; and

      (B) the Current Market Price thereof on that date,

      less the aggregate fair market value, as determined by the board, whose
      determination, absent manifest error, will be conclusive, of the shares,
      rights, options, warrants, evidences of indebtedness or other assets
      issued or distributed in the Special Distribution.

Any Common Shares owned by or held for the account of the Company will be deemed
not to be outstanding for the purpose of any such computation; to the extent
that the distribution of shares, rights, options, warrants, evidences of
indebtedness or assets is not so made or to the extent that any rights, options
or warrants so distributed are not exercised, the Exchange Number will be
readjusted to the Exchange Number that would then be in effect based upon
shares, rights, options, warrants, evidences of indebtedness or assets actually
distributed or based upon the number of Common Shares or Convertible Securities
actually delivered upon the exercise of the rights, options or warrants, as the
case may be, but subject to any other adjustment required hereunder by reason of
any event arising after the record date.

7.6  Capital Reorganization

If and whenever at any time from the date of issuance of the Unit Warrants
during the Exercise Period there is a reorganization of the Company not
otherwise provided for in section 7.3 or a consolidation or merger or
amalgamation of the Company with or into another body corporate or other entity
including a transaction whereby all or substantially all of the Company's
undertaking and assets become the property of any other body corporate, trust,
partnership or other entity (any such event being a "Capital Reorganization"),
any  Warrantholder who has not exercised his Unit Warrants prior to the
effective date of the Capital Reorganization will be entitled to receive and
will accept, upon the exercise of his right at any time after the effective date
of the Capital Reorganization, in lieu of the number of Warrant Shares to which
he would have been entitled upon exercise of the Unit Warrants, the aggregate
number of shares or other securities or property of the Company, or the
continuing, successor or purchasing body corporate, trust, partnership or other
entity, as the case may be, under the Capital Reorganization that the holder
would have been entitled to receive as a result of the Capital Reorganization
if, on the effective date thereof, he had been the holder of the number of
Warrant Shares to which immediately before the transaction he was entitled upon
exercise of the Unit Warrants; no Capital Reorganization will be carried into
effect unless all necessary steps will have been taken so that the holders of
Unit Warrants will thereafter be entitled to receive the number of shares or
other securities or property of the Company, or of the continuing, successor or
purchasing body corporate, trust, partnership or other entity, as the case may
be, under the Capital Reorganization, subject to adjustment thereafter in
accordance with provisions the same, as nearly as may be possible, as those
contained in sections 7.2 to 7.8.  If determined appropriate by the Trustee to
give effect to or to evidence the provisions of this section 7.6, the Company,
its successor, or such purchasing body corporate, partnership, trust or other
entity, as the case may be, shall, prior to or contemporaneously with any such
Capital Reorganization, enter into an indenture which shall provide, to the
extent possible, for the application of the provisions set forth in this
Indenture with respect to the rights and interests thereafter of the

<PAGE>
Page 16

Warrantholders to the end that the provisions set forth in this Indenture shall
thereafter correspondingly be made applicable, as nearly as may reasonably be,
with respect to any shares, other securities or property to which a
Warrantholder is entitled on the exercise of its acquisition rights thereafter.
Any indenture entered into between the Company and the Trustee pursuant to the
provisions of this section 7.6 shall be a supplemental indenture entered into
pursuant to the provisions of Article 11 hereof.  Any indenture entered into
between the Company, any successor to the Company or such purchasing body
corporate, partnership, trust or other entity and the Trustee shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided in this Article 7 and which shall apply to successive
reclassifications, reorganizations, amalgamations, consolidations, mergers,
sales or conveyances.

7.7  Reclassification of Common Shares

If the Company reclassifies or otherwise change the outstanding Common Shares,
the exercise right will be adjusted effective immediately upon the
reclassification becoming effective so that holders of Unit Warrants who
exercise their rights thereafter will be entitled to receive such shares as they
would have received had the Unit Warrants been exercised immediately prior to
the effective date, subject to adjustment thereafter in accordance with
provisions the same, as nearly as may be possible, as those contained in
sections 7.3 to 7.8.

7.8  Subscription Rights Adjustment Rules

The following rules and procedures will be applicable to adjustments made
pursuant to sections 7.3 to 7.7:

(a)  the adjustments and readjustments provided for in this Article 7 are
     cumulative and subject to subsection 7.8(b), will apply (without
     duplication) to successive issues subdivisions, combinations,
     consolidations, distributions and any other events that require adjustment
     of the Exchange Number or the number or kind of shares or securities to be
     issued upon exercise of the Unit Warrants;

(b)  no adjustment in the Exchange Number will be required unless the
     adjustment would result in a change of at least 1% in the Exchange Number
     then in effect provided however, that any adjustments that, except for the
     provisions of this subsection 7.8(b) would otherwise have been required to
     be made, will be carried forward and taken into account in any subsequent
     adjustment;

(c)  no adjustment in the Exchange Number will be made in respect of any event
     described in subsection 7.3(a) or sections 7.4 or 7.5 if the Warrantholders
     are entitled to participate in the event on the same terms mutatis mutandis
     as if they had exercised their Unit Warrants immediately prior to the
     effective date or record date of the event;

(d)  no adjustment in the Exchange Number will be made pursuant to any of
     sections 7.3 to 7.7 in respect of the issue of Warrant Shares issuable from
     time to time as Dividends Paid in the Ordinary Course;

(e)  if a dispute arises with respect to adjustments of the Exchange Number, the
     dispute will be conclusively determined by the auditors of the Company or,
     if they are unable or unwilling to act, by such firm of independent
     chartered accountants as may be selected by the directors of the Company
     and any such determination, absent manifest error, will be binding upon the
     Company, the Trustee and all Warrantholders;

<PAGE>
Page 17

(f)  if during the Exercise Period the Company takes any action affecting the
     Common Shares, other than actions described in this Article, which in the
     opinion of the board of directors of the Company would materially affect
     the rights of the Holder, the Exchange Number will be adjusted in such
     manner, if any, and at such time, by action by the directors of the Company
     in such manner as they may reasonably determine to be equitable in the
     circumstances but subject in all cases to any necessary regulatory
     approval.  Failure of the taking of action by the directors of the Company
     so as to provide for an adjustment on or prior to the effective date of any
     action by the Company affecting the Common Shares will be conclusive
     evidence that the board of directors of the Company has determined that it
     is equitable to make no adjustment in the circumstances; and

(g)  if the Company sets a record date to determine the holders of Common Shares
     for the purpose of entitling them to receive any dividend or distribution
     or any subscription or purchase rights and thereafter legally abandons its
     plans to pay or deliver the dividend, distribution or subscription or
     purchase rights then no adjustment in the Exchange Number will be required
     by reason of the setting of the record date.

7.9  Postponement of Subscription

In any case where the application of any of sections 7.3 to 7.7 results in an
increase of the Exchange Number taking effect immediately after the record date
for or occurrence of a specific event, if any Unit Warrants are exercised after
that record date or occurrence and prior to completion of the event or of the
period for which a calculation is required to be made, the Company may postpone
the issuance, to the Holder, of the Warrant Shares to which the Holder is
entitled by reason of the increase of the Exchange Number but the Warrant Shares
will be so issued and delivered to that holder upon completion of that event or
period, with the number of those Warrant Shares calculated on the basis of the
Exchange Number on the Warrant Exercise Date adjusted for completion of that
event or period, and the Company will forthwith after the Warrant Exercise Date
deliver to the person or persons in whose name or names the Warrant Shares are
to be issued an appropriate instrument evidencing the person's or persons' right
to receive the Warrant Shares.

7.10 Notice of Certain Events

Upon the occurrence of any event referred to in sections 7.3 to 7.8 that
requires an adjustment or readjustment in the Exchange Number, the Company will
promptly thereafter:

(a)  file with the Trustee a certificate of the Company specifying the
     particulars of the event giving rise to the adjustment or readjustment and,
     if determinable, the adjustment and setting forth in reasonable detail a
     computation of the adjustment including the method of computation and which
     certificate shall be supported by a certificate of the Company's auditors
     verifying such calculation; and

(b)  give notice to the Warrantholders of the particulars of the event and, if
     determinable, the adjustment.

If notice has been given under this section 7.10 and the adjustment is not then
determinable, the Company will promptly after the adjustment is determinable:

(a)  file with the Trustee a computation of the adjustment together with a
     certificate of the Company's auditors verifying such calculation; and

<PAGE>
Page 18

(b)  give notice to the Warrantholders of the adjustment.

7.11 Protection of Trustee

The Trustee:

(a)  will not at any time be under any duty or responsibility to any
     Warrantholder to determine whether any facts exist which may require any
     adjustment contemplated by sections 7.3 to 7.7, or with respect to the
     nature or extent of any such adjustment when made, or with respect to the
     method employed in making such adjustment;

(b)  is not accountable with respect to the validity or value (or the kind or
     amount) of any shares or other securities or property which may at any time
     be issued or delivered upon the exercise of the rights attaching to any
     Unit Warrant;

(c)  is not responsible for any failure of the Company to make any cash payment
     or to issue, transfer or deliver Common Shares or certificates for the
     same upon the surrender of any Unit Warrants for the purpose of the
     exercise of such rights or to comply with any of the covenants contained in
     this Article 7; and

(d)  will not incur any liability or responsibility whatever or be in any way
     responsible for the consequence of any breach on the part of the Company of
     any of the representations, warranties or covenants in this Indenture
     contained or any acts of the agents or servants of the Company.

7.12 Entitlement to Common Shares on Exercise of Unit Warrant

All shares of any class or other securities which a Warrantholder is at the time
in question entitled to receive on the exercise of its Unit Warrant, whether or
not as a result of adjustments made pursuant to this section, shall, for the
purposes of the interpretation of this Indenture be deemed to be shares which
such Warrantholder is entitled to acquire pursuant to such Warrant.

7.13 Proceedings Prior to Any Action Requiring Adjustment

As a condition precedent to the taking of any action which would require an
adjustment in any of the acquisition rights pursuant to any of the Unit
Warrants, including the number of Warrant Shares which are to be received upon
the exercise thereof, the Company shall take any corporate action which may, in
the opinion of counsel, be necessary in order that the Company has unissued and
reserved in its authorized capital and may validly and legally issue as fully
paid and non-assessable all the shares which the Warrantholders are entitled to
receive on the full exercise thereof in accordance with the provisions hereof.

7.14 Notice of Special Matters

The Company covenants with the Trustee that, so long as any Unit Warrant remains
outstanding, it will give notice to the Trustee and to the Warrantholders of its
intention to fix the record date for the issuance of rights, options or warrants
(other than the Unit Warrants) to all or substantially all of the holders of its
outstanding Common Shares.  Such notice shall specify the particulars of such

<PAGE>
Page 19

event, to the extent determinable, any adjustment required and the computation
of such adjustment and the record date for such event, provided that the Company
shall only be required to specify in the notice such particulars of the event as
shall have been fixed and determined on the date on which the notice is given.
The notice shall be given in each cash not less than fourteen days prior to such
applicable record date.  If any adjustment for which notice is given is not then
determinable, the Company shall, promptly after such adjustment is determinable,
give notice.

                                   ENFORCEMENT

9.1  Suits by Warrantholders

All or any of the rights conferred upon a Warrantholder by the terms of a Unit
Warrant or of this Indenture may be enforced by the holder by appropriate legal
proceedings but without prejudice to the right that is hereby conferred upon the

<PAGE>
Page 21

9.2  Immunity of Shareholders, Officers & Directors

The Trustee, and by their acceptance of the Warrant Certificates and as part of
the consideration for the issue of the Unit Warrants, the Warrantholders, hereby
waive and release any right, cause of action or remedy now or hereafter existing
in any jurisdiction against any past, present or future shareholder, director,
officer, employee or agent of the Company in their capacity as such, either
directly or through the Company, relating to any obligations, representations,
warranties and covenants under the Unit Warrants or this Indenture, it being
acknowledged that all such obligations, representations, warranties and
covenants are solely those of the Company.  Accordingly, the obligations under
the Unit Warrants and this Indenture are not personally binding upon, nor will
resort hereunder be had to, the private properly of any of the past, present or

exercise any right or power accruing upon any default shall impair any such
right or power or shall be construed to be a waiver of any such default or
acquiescence therein and provided further that no act or omission either of the
Trustee or of the Warrantholders in the premises shall extend to or be taken in
any manner whatsoever to affect any subsequent default hereunder of the rights
resulting therefrom.

                                   ARTICLE 10
                           MEETINGS OF WARRANTHOLDERS

indemnified to its reasonable satisfaction by the Company or by the
Warrantholders signing the Warrantholders' Request against the cost that may be
incurred in connection with the calling and holding of the meeting, convene a
meeting of the Warrantholders. If, within 21 days after receipt of the written
request of the Company or Warrantholders' Request and such indemnity has been
given, the Trustee fails to give notice convening a meeting, the Company or the
Warrantholders, as the case may be, may convene the meeting. Every meeting will
be held in the City of Vancouver or at such other place as may be approved or
determined by the Trustee.

<PAGE>
Page 22

the manner provided in section 13.2 and a copy of the notice will be sent by
mail to the Trustee unless the meeting has been called by it, and to the Company
unless the meeting has been called by it. Each notice will state the time when
and the place where the meeting is to be held and will state briefly the general
nature of the business to be transacted thereat and shall contain such
information as is reasonably necessary to enable the Warrantholders to make a
reasoned decision on the matter but it will not be necessary for the notice to
set out the terms of any resolution to be proposed or any of the provisions of
this Article 10.

10.3 Chairman

A person, who need not be a Warrantholder, designated in writing by the Trustee
will chair the meeting and if no person is so nominated, or if the person so
nominated is not present within 15 minutes from the time fixed for the holding
of the meeting, the Warrantholders present in person or by proxy will choose a
person present to chair the meeting.

10.4 Quorum

With respect to the quorum required for a meeting of Warrantholders:

(a)  subject to the provisions of section 10.12, at any meeting of the
     Warrantholders a quorum will consist of Warrantholders present in person or
     by proxy constituting at least 20% of the aggregate number of Unit Warrants
     then outstanding, provided at least two persons entitled to vote thereat
     are personally present;

(b)  if a quorum of the Warrantholders is not present within 30 minutes from the
     time fixed for holding any meeting, the meeting, if summoned by the
     Warrantholders or on a Warrantholders' Request, will be dissolved; but,
     subject to section 10.12, in any other case the meeting will be adjourned
     to the same day in the next week (unless that day is not a business day, in
     which event the meeting will be reconvened on the next day that is a
     business day) at the same time and place and no notice need be given; and

(c)  at the adjourned meeting, the Warrantholders present in person or by proxy
     will form a quorum and may transact the business for which the meeting was
     originally convened, notwithstanding that they may not hold at least 20% of
     the aggregate number of Unit Warrants then outstanding.

10.5 Power to Adjourn

The chairman of any meeting at which a quorum of the Warrantholders is present
may, with the consent of the meeting, adjourn the meeting and no notice of the
adjournment need be given except such notice, if any, as the meeting may
prescribe.

10.6 Show of Hands

Every question submitted to a meeting will be decided in the first place by a
majority of the votes given on a show of hands except that votes on an Special
Resolution will be given in the manner provided in section 10.12. At any

<PAGE>
Page 23

meeting, unless a poll is duly demanded as herein provided, a declaration by the
chairman that a resolution has been carried or carried unanimously or by a
particular majority or lost or not carried by a particular majority will be
conclusive evidence of the fact.

10.7 Poll

On every Special Resolution, and on any other question submitted to a meeting
upon which a poll is directed by the chairman or requested by one or more of the
Warrantholders acting in person or by proxy and representing in the aggregate at
least 5% of the aggregate number of Unit Warrants then outstanding, a poll will
be taken in such manner as the chairman will direct. Questions other than an
Special Resolution will be decided by a majority of the votes cast on a poll.

10.8 Voting

On a show of hands every person who is present and entitled to vote, whether as
a Warrantholder or as proxy for one or more absent Warrantholders or both, will
have one vote. On a poll each Warrantholder present in person or represented by
a proxy duly appointed by instrument in writing will be entitled to one vote in
respect of each Unit Warrant then held by him. A proxy need not be a
Warrantholder.

10.9 Regulations

The Trustee or the Company with the approval of the Trustee may from time to
time make or vary such regulations as they will think fit:

(a)  the setting of the record date for a meeting for the purpose of determining
     Warrantholders entitled to receive notice of and to vote at the meeting;

(b)  for the issue of voting certificates by any bank, trust company or other
     depositary satisfactory to the Trustee stating that the Unit Warrants
     specified therein have been deposited with the depository by a named person
     and will remain on deposit until after the meeting, which voting
     certificates will entitle the persons named therein to be present and vote
     at the meeting and at any adjournment thereof or to appoint a proxy or
     proxies to represent them and vote for them at that meeting and at any
     adjournment thereof in the same manner and with the same effect as though
     the persons so named in the voting certificates were the actual holders of
     the Unit Warrants specified therein;

(c)  for the deposit of voting certificates and/or instruments appointing
     proxies at such place and time as the Trustee, the Company or the
     Warrantholders convening the meeting, as the case may be, may in the notice
     convening the meeting direct;

(d)  for the deposit of voting certificates and/or instruments appointing
     proxies at some approved place or places other than the place at which the
     meeting is to be held and enabling particulars of the voting certificates
     and/or instruments appointing proxies to be sent by mail, cable, fax or
     other means of prepaid, transmitted, recorded communication before the
     meeting to the Company or to the Trustee at the place where the same is to
     be held and for the voting of proxies so deposited as though the
     instruments themselves were produced at the meeting;

(e)  for the form of instrument appointing a proxy; and

<PAGE>
Page 24

(f)  generally for the calling of meetings of Warrantholders and the conduct of
     business thereat.

Any regulations so made will be binding and effective and the votes given in
accordance therewith will be valid and will be counted. Except as the
regulations may provide, the only persons who will be recognized at any meeting
as the holders of any Special Warrants, or as entitled to vote or, subject to
section 10.10, be present at the meeting in respect thereof, will be persons who
are the registered holders of Unit Warrants or their duly appointed proxies.

10.10 Company and Trustee may be Represented

The Company and the Trustee by their respective officers or directors, and the
counsel to the Company and the Trustee may attend any meeting of the
Warrantholders, but will have no vote as such.

this Indenture or by law the Warrantholders at a meeting will have the following
powers exercisable from time to time by Special Resolution:

     arrangement of the rights of Warrantholders and/or the Trustee in its

     Unit Warrant certificates;

(b)  power to direct or authorize the Trustee to enforce any of the covenants on
     the part of the Company contained in this Indenture or the Unit Warrants or

     right;

(c)  power to restrain any Warrantholder from taking or instituting any suit,

     provisions of section 8.3;

(d)  power to direct any Warrantholder who, as such, has brought any suit,
     action or proceeding to stay or discontinue or otherwise deal with the same
     upon payment of the costs, charges and expenses reasonably and properly
     incurred by the Warrantholder in connection therewith;

10.12 Meaning of "Special Resolution"

(a)  The expression "Special Resolution" when used in this Indenture means,
     subject to the provisions in this subsection 10.12(b) and 10.12(c) and in
     sections 10.15 and 10.16 provided, a resolution proposed at a meeting of
     the Warrantholders duly convened for that purpose and held in accordance
     with the provisions of this Article 10 at which there are present in person
     or by proxy Warrantholders holding at least 20% of the aggregate of the
     Unit Warrants then outstanding and passed by the affirmative votes of
     Warrantholders holding not less than two-thirds of the aggregate number of

     resolution.

(b)  If, at any meeting called for the purpose of passing a Special Resolution,
     Warrantholders entitled to acquire 51% of the aggregate number of Unit
     Warrants then outstanding are not present in person or by proxy within 30
     minutes after the time appointed for the meeting, then the meeting, if
     convened by Warrantholders or on a Warrantholders' Request, will be
     dissolved; but in any other case it will stand adjourned to such day, being
     not less than 15 or more than 60 days later, and to such place and time as
     may be appointed by the chairman. Not less than 10 days' notice will be
     given of the time and place of the adjourned meeting in the manner provided
     in section 13.2. The notice will state that at the adjourned meeting the
     Warrantholders present in person or by proxy will form a quorum but it will
     not be necessary to set forth the purposes for which the meeting was
     originally called or any other particulars. At the adjourned meeting the
     Warrantholders present in person or by proxy will form a quorum and may
     transact the business for which the meeting was originally convened and a
     resolution proposed at the adjourned meeting and passed by the requisite
     vote as provided in subsection 10.12(a) will be a Special Resolution
     within the meaning of this Indenture notwithstanding that Warrantholders
     holding at least 20% of the aggregate number of Unit Warrants then
     outstanding are not present in person or by proxy at the adjourned meeting.

(c)  Votes on a Special Resolution will always be given on a poll and no demand
     for a poll on a Special Resolution will be necessary.

10.13 Powers Cumulative

It is hereby declared and agreed that any one or more of the powers or any
combination of the powers in this Indenture stated to be exercisable by the
Warrantholders by Special Resolution or otherwise may be exercised from time to
time and the exercise of any one or more of the powers or any combination of the
powers from time to time will not be deemed to exhaust the right of the
Warrantholders to exercise that power or those powers or combination of powers
then or any other power or powers or combination of powers thereafter from time
to time.

10.14 Minutes

Minutes of all resolutions and proceedings at every meeting of Warrantholders
convened and held pursuant to this Article 10 will be made and duly entered in
books to be provided for that purpose by the Trustee at the expense of the
Company, and any such minutes, if signed by the chairman of the meeting at which
resolutions were passed or proceedings had, or by the chairman of the next
succeeding meeting of the Warrantholders, will be prima facie evidence of the
matters as stated in the minutes and, until the contrary is proved, every
meeting, in respect of the proceedings of which minutes will have been made,

<PAGE>
Page 26

will be deemed to have been duly convened and held, and all resolutions passed
thereat or proceedings taken, to have been duly passed and taken.

10.15 Instruments in Writing

Warrantholders at a meeting held as provided in this Article 10 may also be

provisions of this Article 10 at a meeting of Warrantholders will be binding
upon all the Warrantholders, whether present at or absent from the meeting, and
every instrument in writing signed by Warrantholders in accordance with section
10.15 will be binding upon all the Warrantholders, whether signatories thereto
or not, and each and every Warrantholder and the Trustee (subject to the
provisions for its indemnity herein contained) will be bound to give effect
accordingly to every resolution and instrument in writing passed or executed in
accordance with these provisions.

10.17 Holdings by Company Disregarded

In determining whether the requisite number of Warrantholders are present for
the purpose of obtaining a quorum or have voted or consented to any resolution,
Special Resolution, consent, waiver, Warrantholders' Request or other action
under this Indenture, Unit Warrants owned by the Company or any subsidiary of
the Company will be deemed to be not outstanding.

     transfer of Unit Warrants, making provision for the exchange of Unit
     Warrants, and making any modification in the form of the Unit Warrants that
     does not affect the substance of the Unit Warrants;

(f)  modifying any of the provisions of this Indenture or relieving the Company
     from any of the obligations, conditions or restrictions contained in this
     Indenture, provided that no such modification or relief will be or become
     operative or effective if in the opinion of counsel to the Trustee the
     modification or relief impairs any of the rights of the Warrantholders, as
     a group, or of the Trustee, and provided that the Trustee may in its
     uncontrolled discretion decline to enter into any supplemental indenture
     which in its opinion may not afford adequate protection to the Trustee when
     the such supplemental indenture becomes operative; and

(g)  for any other purpose not inconsistent with the terms of this Indenture,
     including the correction or rectification of any ambiguities, defective
     provisions, errors or omissions in this Indenture, provided that in the
     opinion of counsel to the Trustee the rights of the Trustee and the
     Warrantholders, as a group, are in no way prejudiced thereby.

11.2  Successor Companies

In the case of the consolidation, amalgamation, merger or transfer of the
undertaking or assets of the Company as an entirety or substantially as an
entirety to another corporation ("successor corporation"), the successor
corporation resulting from the consolidation, amalgamation, merger or transfer
(if not the Company) will be bound by the provisions of this Indenture and all
obligations for the due and punctual performance and observance of each and
every covenant and obligation contained in this Indenture to be performed by the
Company and, if requested by the Trustee, the successor corporation will, by
supplemental indenture satisfactory in form to the Trustee and executed and
delivered to the Trustee, expressly assume those obligations.

                                   ARTICLE 12
                             CONCERNING THE TRUSTEE

12.1  Trust Indenture Legislation

If and to the extent that any provision of this Indenture limits, qualifies or
conflicts with a mandatory requirement of Applicable Legislation, the mandatory
requirement will prevail. The Company and the Trustee agree that each will at
all times, in relation to this Indenture and any action to be taken under this
Indenture, observe and comply with and be entitled to the benefits of Applicable
Legislation.

12.2  Rights and Duties of Trustee

The rights and duties of the Trustee are as follows:

(a)  In the exercise of the rights and duties prescribed or conferred by the
     terms of this Indenture, the Trustee will act honestly and in good faith
     with a view to the best interests of the Warrantholders and will exercise
     that degree of care, diligence and skill that a reasonably prudent trustee
     would exercise in comparable circumstances.  In the absence of negligence
     or fraud, the Company shall indemnify and save harmless the Trustee from
     all loss, costs or damages it may suffer in administering the trusts of
     this Indenture.  No provision of this Indenture shall be construed to
     relieve the Trustee from liability for its own negligent action, its own
     negligent failure to act, or its own negligence or fraud;

(b)  The obligation of the Trustee to commence or continue any act, action or
     proceeding for the purpose of enforcing any rights of the Trustee or the
     Warrantholders under this Indenture will be conditional upon the
     Warrantholders furnishing, when required by notice in writing by the
     Trustee, sufficient funds to commence or continue the act, action or
     proceeding and indemnity reasonably satisfactory to the Trustee to protect
     and hold harmless the Trustee against the costs, charges and expenses and
     liabilities to be incurred thereby and any loss and damage it may suffer by
     reason thereof. None of the provisions contained in this Indenture will
     require the Trustee to expend or risk its own funds or otherwise incur
     financial liability in the performance of any of its duties or in the
     exercise of any of its rights or powers unless indemnified and funded as
     required in this subsection 12.2(b);

(c)  The Trustee may, before commencing action or proceeding, or at any time
     during the continuance thereof, require the Warrantholders at whose
     instance it is acting to deposit with the Trustee the Warrant Certificates
     held by them, for which Warrant Certificates the Trustee will issue
     receipts; and

(d)  Every provision of this Indenture that by its terms relieves the Trustee of
     liability or entitles it to rely upon any evidence submitted to it is
     subject to the provisions of the Applicable Legislation, of this  section
     12.2 and of section 12.4.

12.3  Evidence, Experts and Advisers

(a)  In addition to the reports, certificates, opinions and other evidence
     required by this Indenture, the Company will furnish to the Trustee such
     additional evidence of compliance with any provision of this Indenture, and
     in such form, as may be prescribed by Applicable Legislation or as the
     Trustee may reasonably require by written notice to the Company.

(b)  In the exercise of its rights and duties, the Trustee may, if it is acting
     in good faith, rely as to the truth of the statements and the accuracy of
     the opinions expressed therein, upon statutory declarations, opinions,
     reports, certificates or other evidence furnished to the Trustee pursuant
     to any provision of this Indenture or of Applicable Legislation or pursuant
     to a request of the Trustee, provided that the Trustee examines the
     evidence and determines that the evidence complies with the applicable
     requirements of this Indenture.

<PAGE>
Page 29

(c)  Whenever Applicable Legislation requires that evidence referred to in
     subsection 12.3(a) be in the form of a statutory declaration, the Trustee
     may accept a statutory declaration in lieu of a certificate of the Company
     required by any provision of this Indenture. Any such statutory declaration
     may be made by one or more of the officers of the Company.

(d)  The Trustee may employ or retain such counsel, accountants, engineers,
     appraisers, or other experts or advisers as it may reasonably require for
     the purpose of discharging its duties under this Indenture and may pay
     reasonable remuneration for all services so performed by any of them,
     without taxation of costs of any counsel, and will not be responsible for
     any misconduct on the part of any of them.

(e)  The Trustee may, as a condition precedent to any action to be taken by it
     under this Indenture, require such opinions, statutory declarations,
     reports, certificates or other evidence as it, acting reasonably, considers
     necessary or advisable in the circumstances.

(f)  Proof of the execution of an instrument in writing, including a
     Warrantholder's Request, by any Warrantholder may be made by the
     certificate of a notary public, or other officer with similar powers, that
     the person signing such instrument acknowledges to the execution thereof,
     or by an affidavit of a witness to such execution or in any other manner
     which the Trustee may consider adequate.

12.4  Securities, Documents and Monies Held by Trustee

Any securities, documents of title or other instruments that may at any time be
held by the Trustee subject to the trusts hereof may be placed in the deposit
vaults of the Trustee or of any of the Canadian Imperial Bank of Commerce, Bank
of Montreal, Bank of Nova Scotia, The Toronto-Dominion Bank, the Royal Bank of
Canada and the Hongkong Bank of Canada or deposited for safekeeping with any of
those Canadian chartered banks. Unless otherwise expressly provided in this
Indenture, any monies held pending the application or withdrawal thereof under
any provision of this Indenture, may be deposited in the name of the Trustee in
any of the foregoing Canadian chartered banks at the rate of interest then
current on similar deposits or, with the consent of the Company may be (i)
deposited in the deposit department of the Trustee or any other loan or trust
company authorized to accept deposits under the laws of Canada or a province
thereof whose short term debt obligations or deposits have a rating of at least
R1 as rated by Dominion Bond Rating Service, or (ii) invested in securities
issued or guaranteed by the Government of Canada or a province thereof or in
obligations, maturing not more than one year from the date of investment, of or
guaranteed by any of the foregoing Canadian chartered banks or loan or trust
companies. All interest or other income received by the Trustee in respect of
such deposits and investments will belong to the Company.

12.5  Action by Trustee to Protect Interests

The Trustee will have power to institute and to maintain such actions and
proceedings as it may consider necessary or expedient to preserve, protect or
enforce its interests and the interests of the holders of Unit  Warrants.

12.6  Trustee not Required to Give Security

The Trustee will not be required to give any bond or security in respect of the
execution of the trusts and powers of this Indenture or otherwise in respect of
the premises.

<PAGE>
Page 30

12.7  Protection of Trustee

By way of supplement to the provisions of any law for the time being relating to
trustees, it is expressly declared and agreed as follows:

(a)  the Trustee will not be liable for or by reason of any representations,
     statements of fact or recitals in this Indenture or in the Unit Warrants
     (except the representation contained in section 12.9 or in the certificate
     of the Trustee on the Unit Warrants) or required to verify the same, but
     all those statements or recitals are and will be deemed to be made by the
     Company;

(b)  nothing in this Indenture will impose any obligation on the Trustee to see
     to or to require evidence of the registration (or filing or renewal
     thereof) of this Indenture or any instrument ancillary or supplemental to
     this Indenture;

(c)  the Trustee will not be bound to give notice to any person or persons of
     the execution of this Indenture;

(d)  the Trustee shall not incur any liability or responsibility whatever or be
     in any way responsible for the consequence of any breach on the part of the
     Company of any of the covenants herein contained or of any acts of any
     directors, officers, employees, agents or servants of the Company; and

(e)  the Trustee shall not be bound to give any notice or do or take any act,
     action or proceeding by virtue of the powers conferred on it hereby unless
     it shall have been required to do so under the terms hereof; nor shall the
     Trustee be required to take notice of any default hereunder, unless and
     until notified in writing of such default, which notice shall distinctly
     specify the default desired to be brought to the attention of the Trustee
     and in the absence of any such notice the Trustee may for all purposes of
     this Indenture conclusively assume that no default has been made in the
     observance or performance of any of the representations, warranties,
     covenants, agreements or conditions contained herein.  Any such notice
     shall in no way limit any discretion herein given to the Trustee to
     determine whether or not the Trustee shall take action with respect to any
     default.

12.8  Replacement of Trustee

(a)  The Trustee may resign its trust and be discharged from all further
     duties and liabilities under this Indenture by giving to the Company not
     less than 90 days' notice in writing or such shorter notice as the Company
     may accept as sufficient. The Warrantholders by Special Resolution will
     have power at any time to remove the Trustee and to appoint a new Trustee.
     In the event of the Trustee resigning or being removed as pursuant to this
     subsection 12.8(a) or being dissolved, becoming bankrupt, going into
     liquidation or otherwise becoming incapable of acting under this Indenture,
     the Company will forthwith appoint a new Trustee unless a new Trustee has
     already been appointed by the Warrantholders; failing that appointment by
     the Company the retiring Trustee or any Warrantholder may apply to a
     Justice of the Supreme Court of British Columbia, on such notice as the
     Justice may direct, for the appointment of a new Trustee; but any new
     Trustee so appointed the Company or by the Court will be subject to removal
     as aforesaid by the Warrantholders. Any new Trustee appointed under any
     provision of this section 12.8 will be a corporation authorized to carry on
     the business of a trust company in the Province of British Columbia and, if
     required by the Applicable Legislation of any other Province, in that other
     Province. On any appointment the new Trustee will be vested with the same

<PAGE>
Page 31

     powers, rights, duties and responsibilities as if it had been originally
     named in this Indenture as Trustee without any further assurance,
     conveyance, act or deed; but there will be immediately executed, at the
     expense of the Company, all such conveyances or other instruments as may,
     in the opinion of counsel, be necessary or advisable for the purpose of
     assuring the same of the new Trustee.

(b)  Upon the appointment of a new Trustee, the Company will promptly give
     notice to the Warrantholders of the new Trustee.

(c)  Any corporation into or with which the Trustee may be merged or
     consolidated or amalgamated, or any corporation succeeding to the trust
     business of the Trustee will be the successor to the Trustee under this
     Indenture without any further act on its  part or any of the parties
     hereto provided that the corporation would be eligible for appointment as
     a new Trustee under subsection 12.8(a).

(d)  Any Unit Warrants certified but not delivered by a predecessor Trustee may
     be certified by the new or successor Trustee in the name of the predecessor
     or new or successor Trustee.

12.9  Conflict of Interest

(a)  The Trustee represents to the Company that at the time of the execution and
     delivery of this Indenture no material conflict of interest exists in the
     Trustee's role as a fiduciary under this Indenture and agrees that in the
     event of a material conflict of interest it will, within 90 days after
     ascertaining that it has a material conflict of interest, either eliminate
     the same or resign its trust under this Indenture to a successor trustee
     approved by the Company and meeting the requirements set forth in section
     12.8.  Notwithstanding the foregoing provisions of this section 12.9(a), if
     any such material conflict of interest exists or hereafter shall exist, the
     validity and enforceability of this Indenture and the Warrant Certificate
     shall not be affected in any manner whatsoever by reason thereof.

(b)  Subject to subsection 12.9(a), the Trustee, in its personal or any other
     capacity may buy, lend upon and deal in securities of the Company, may act
     as registrar and transfer agent for the Common Shares and trustee for the
     Special Warrants under the Special Warrant Indenture, and generally may
     contract and enter into financial transactions with the Company or any
     subsidiary of the Company, all without being liable to account for any
     profit made thereby.

12.10 Acceptance of Trust

The Trustee hereby accepts the trusts declared and provided for in this
Indenture, agrees to perform the same upon the terms and conditions set out in
this Indenture and agrees to hold all rights, interests and benefits contained
in this Indenture for and on behalf of those persons who become holders of Unit
Warrants from time to time issued pursuant to this Indenture.

12.11 Indemnity

Without limiting any protection or indemnity of the Trustee under any other
provisions hereof, or otherwise at law, the Company hereby agrees to indemnify
and hold harmless the Trustee from and against any and all liabilities, losses,
damages, penalties, claims, actions, suits, costs, expenses and disbursements,

<PAGE>
Page 32

including reasonable legal or advisor fees and disbursements, of whatever kind
and nature which may at any time be imposed on, incurred by or asserted against
the Trustee in connection with the performance of its duties and obligations
hereunder, other than such liabilities, losses, damages, penalties, claims,
actions, suits, costs, expenses and disbursements arising by reason of the
negligence or fraud of the Trustee.  This provision shall survive the
resignation or removal of the Trustee, or the termination of the Indenture.  The
Trustee shall not be under any obligation to prosecute or to defend any action
or suit in respect of the relationship which, in the opinion of its counsel, may
involve it in expense or liability, unless the Company shall, so often as
required, furnish the Trustee with satisfactory indemnity and funding against
such expense or liability.

12.12 Survival on Termination

The indemnity of the Trustee provided for herein shall survive the termination
of this Indenture and the rights and obligations of the parties hereunder.

12.13 Unit Warrants Owned by the Company or its Subsidiaries

For the purpose of disregarding any Unit Warrants owned legally or beneficially
by the Company or any Subsidiary of the Company in Section 7.4, the Company
shall provide to the Trustee, from time to time, a certificate of the Company
setting forth as at the date of such certificate:

(a)  the names (other than the name of the Company) of the registered holders of
     Unit Warrants which, to the knowledge of the Company, are owned by or held
     for the account of the Company or any Subsidiary of the Company; and

(b)  the number of Unit Warrants owned legally or beneficially by the Company or
     any Subsidiary of the Company,

and the Trustee, in making the computations in Section 7.4, shall be entitled to
rely on such certificate without any additional evidence.

           Fax:           (604) 665-4079

     and any notice given in accordance with the foregoing will be deemed to
     have been received on the date of delivery or, if mailed, on the fifth
     business day following the day of the mailing of the notice or, if
     transmitted by fax, at the time of transmission.

(b)  The Company or the Trustee, as the case may be, may from time to time
     notify the other, in the manner provided above, of a change of address
     which, from the effective date of the notice and until changed by like
     notice, will be the address of the Company or the Trustee, as the case
     may be, for all purposes of this Indenture.

(c)  If, by reason of a strike, lockout or other work stoppage, actual or
     threatened, involving postal employees, any notice to be given to the
     Trustee or to the Company under this Indenture could reasonably be
     considered unlikely to reach its destination, the notice will be valid and
     effective only if it is delivered to an officer of the party to which it is
     addressed or if it is delivered to that party at the appropriate address
     provided above by cable, telegram, telex, fax or other means of prepaid,
     transmitted, or recorded communication and any notice delivered in
     accordance with the foregoing will be deemed to have been received on the

     fax or other means of prepaid, transmitted, recorded communication, on the
     first business day following the date of the sending of the notice by the
     person giving the notice.

13.2  Notice to Warrantholders

(a)  Unless otherwise expressly provided in this Indenture, any notice to be
     given under this Indenture to Warrantholders will be deemed to be validly
     given if the notice is sent by prepaid mail, addressed to the holder or
     delivered by hand or transmitted by fax (or so mailed to certain holders
     and so delivered to other holders and so faxed to other holders) at their
     respective addresses and fax number appearing on the register maintained by
     the Trustee and if in the case of joint holders of any Unit Warrants more
     than one address or fax number appears on the register in respect of that
     joint holding, the notice will be addressed or delivered, as the case may

<PAGE>
Page 34

     be, only to the first address or fax number, as the case may be so
     appearing.  The Trustee will give, in the same manner as for Warrantholders
     set out above, a copy of each such notice to Maitland & Company, Barristers
     & Solicitors, 700 - 625 Howe Street, Vancouver, British Columbia, V6C 2T6
     (fax no.: (604) 681-3896) (Attention: Ronald G. Paton). Any notice so given
     will be deemed to have been given and received on the day of delivery by
     hand or fax, or on the next business day if delivered by mail.

(b)  If, by reason of strike, lock-out or other work stoppage, actual or
     threatened, involving postal employees, any notice to be given to the
     Warrantholders could reasonably be considered unlikely to reach its
     destination, the notice may be published or distributed once in The Globe
     and Mail newspaper, or, in the event of a disruption in the circulation of
     that newspaper, once in the National Post provided that in the case of a
     notice convening a meeting of the holders of Unit Warrants, the Trustee may
     require such additional publications of that notice, in the same or in
     other cities or both, as it may deem necessary for the reasonable
     protection of the holders of Unit Warrants or to comply with any applicable
     requirement of law or any stock exchange. Any notice so given will be
     deemed to have been given on the day on which it has been published in all
     of the cities in which publication was required (or first published in a
     city if more than one publication in that city is required). In
     determining, under any provision of this Indenture, the date when notice of
     any meeting or other event must be given, the date of giving notice will be
     included and the date of the meeting or other event will be excluded.

13.3  Satisfaction and Discharge of Indenture

Upon the date which there shall have been delivered to the Trustee for exercise
all Unit Warrant Certificates certified hereunder and if all certificates
representing Warrant Shares will have been delivered to Warrantholders to the
full extent of the rights attached to all Unit Warrants theretofore certified
under this Indenture and the monies to be paid under this Indenture have been
paid, this Indenture will cease to be of further effect and the Trustee, on
demand of and at the cost and expense of the Company and upon delivery to the
Trustee of a certificate of the Company stating that all conditions precedent to
the satisfaction and discharge of this Indenture have been complied with and
upon payment to the Trustee of the fees and other remuneration payable to the
Trustee, the parties hereto will execute proper instruments acknowledging
satisfaction of and discharging this Indenture.  Notwithstanding the foregoing,
the indemnities provided to the Trustee by the Company shall remain in full
force and effect and survive the termination of this Indenture.

13.4  Sole Benefit of Parties and Warrantholders

Nothing in this Indenture or in the Unit Warrants, expressed or implied, will
give or be construed to give to any person other than the parties hereto and the
Warrantholders any legal or equitable right, remedy or claim under this
Indenture, or under any covenant or provision therein contained, all such
covenants and provisions being for the sole benefit of the parties hereto and
the Warrantholders.

13.5  Counterparts and Formal Date

This Indenture may be simultaneously executed in several counterparts, each of
which when so executed will be deemed to be an original and the counterparts
together will constitute one and the same instrument and notwithstanding their
date of execution will be deemed to bear the date as of March 9, 2000.

<PAGE>
Page 35

13.6  Successors

This Agreement shall enure to the benefit of, and be binding upon, the Company
and the Trustee and their respective successors (including successors by reason
of amalgamation, merger, business combination or arrangement) and legal
representatives and nothing expresses or mentioned in this Agreement is intended
and shall be construed to give any other person any legal or equitable right,
remedy or claim under or in respect of this Agreement, or any provision herein
contained, this Agreement and all conditions and provisions hereof being
intended to be and being for the sole and exclusive benefit of such persons and
for the benefit of no other person.

IN WITNESS WHEREOF the parties have caused this Indenture to be executed by
their proper officers in that behalf.
