                               PROSPECTUS SUMMARY

                                   The Company

Ltd., an Alberta, Canada,  corporation,  and HealthCare Hearing Clinics, Inc., a
Washington corporation, currently owns and operates a network of 50 hearing care

                                      - 3 -




<PAGE>




         Each  of the  Company's  hearing  care  clinics  provides  its  hearing
impaired patients with a full range of audiological  products and services.  All
of the Company's  hearing care clinics are staffed by  audiologists,  except for
one clinic  that is  staffed by a hearing  instrument  specialist  ("HIS").  The
Company's  operating  strategy  is to provide  patients  with high  quality  and
cost-effective  hearing  care while at the same time  increasing  its  operating
margins  by  attracting  and  retaining  patients,   recruiting   qualified  and
productive  audiologists,   achieving  economies  of  scale  and  administrative
efficiencies,  and pursuing large group and managed care contracts.  The Company
believes that it is well  positioned to provide  retail  hearing  rehabilitative
services to  consumers  while  simultaneously  serving the  diagnostic  needs of
referring  physicians  and meeting the access and cost  concerns of managed care
providers and insurance companies.

         The Company was incorporated under the laws of the Province of Alberta,
Canada in July 1993,  under the name "575035  Alberta Ltd." The Company  changed
its name to HealthCare  Capital Corp. in October 1994.  The Company's  executive
offices are located at Suite 2390, 111 S.W. Fifth Avenue, Portland, Oregon 97204
(telephone  (503)  225-9152)  and an additional  corporate  office is located at
Suite 1120, 595 Howe Street, Vancouver, B.C. V6B 1NZ (telephone (604) 685-4854).

         The summary  historical  financial data  presented  below for the years
ended  July  31,  1995 and 1996 has  been  derived  from the  audited  financial

should be read in  conjunction  with the financial  statements and notes thereto

                                  RISK FACTORS

         The Company's  Common Stock,  without nominal or par value (the "Common
Stock"),  offered hereby should be considered a highly  speculative  investment.
Prospective  investors  should  carefully  consider the  following  factors,  in
addition to the other information  contained herein, before deciding to purchase
the Common Stock. This Prospectus contains forward-looking statements within the
meaning of the federal securities laws. Such forward-looking  statements involve
risks and uncertainties,  and actual results may differ from those projected due
to a number of factors,  including  those set forth below and  elsewhere in this
Prospectus. See "Special Note Regarding Forward-Looking Statements."

Short Operating History

         The Company has a limited history of operations consisting primarily of
operating a limited number of hearing care clinics in British Columbia beginning
in October 1994. The Company did not begin  operating in the United States until
it purchased two hearing care clinics in Santa Maria, California,  in July 1996.
At March 1, 1997,  the Company  operated 37 hearing  care  clinics in the United
States and 13 clinics in Canada.

Operating Losses

         For the fiscal year ended July 31,  1996,  the Company  sustained a net
loss of approximately $582,000. For the three months ended October 31, 1996, the
Company had a net loss of approximately $301,000. Further losses are anticipated
as a result of planned  increases in the executive and general  management staff
of the Company to support the Company's expansion plans,  additional advertising
and public relations costs,  amortization of goodwill related to past and future
acquisitions,  and the development of a management information system. There can
be no assurance that the Company will achieve  profitability in the near or long
term.

Expansion Program

         Much of the  Company's  future  success  is  dependent  upon  acquiring
hearing  care  clinics  in new  markets  in which the  Company  has no  previous
presence.  There can be no  assurance  that the Company will be able to complete
acquisitions consistent with its expansion plans, that such acquisitions will be
on  terms  favorable  to the  Company  or  that  the  Company  will  be  able to
successfully  integrate  the hearing  care  clinics  that it  acquires  into its
business.  The success of the Company's  expansion is dependent upon its ability
to  establish a market  presence in  geographic  areas in which it is  presently
unknown and where  competitors with greater financial and other resources may be
operating  and on a  number  of other  factors,  some of which  are  beyond  the
Company's control.  Unforeseen  problems with future  acquisitions and expansion
may have a material  adverse effect on the business,  financial  condition,  and
results of  operations of the Company.  In addition,  clinics in areas of recent
expansion are not expected to be profitable for an indeterminate  period of time
because of the time and capital required to develop


                                      - 7 -




<PAGE>



a network of hearing  care  clinics  that is  sufficiently  large to permit full
implementation of the Company's business strategy.  The Company intends to issue
additional  shares of its  Common  Stock in  payment  of all or a portion of the
purchase  price  of  certain  acquisitions.  There  can  be  no  assurance  that
fluctuations  in the market price of the Common Stock will not adversely  affect
the Company's ability to use its Common Stock for acquisitions.

Integration of Acquired Hearing Care Clinics

         The  Company's  expansion  into new markets will require the Company to
establish  and  maintain  payor and  customer  relationships  and to convert the
patient  tracking and  financial  reporting  systems of the hearing care clinics
that it acquires  to the  Company's  systems.  The  failure to  efficiently  and
effectively  establish and maintain  payor and customer  relationships,  convert
management  information systems, and integrate new hearing care clinics into its
existing network will have a material adverse effect on the Company's  business,
financial condition, and results of operations.

Impact of Policy Changes by Third-Party Insurers

         A  portion  of the  hearing  aids sold by the  Company  are paid for by
third-party insurers.  Many of such insurers impose restrictions in their health
insurance  policies  on the  frequency  with which  hearing  instruments  may be
upgraded or replaced on a reimbursable  basis. Such restrictions have a negative
impact on hearing aid sales volume. There can be no guarantee that such insurers
will not implement  other policy  restrictions in the future in order to further
minimize reimbursement for hearing care. Such restrictions could have a material
adverse effect on the Company's business,  financial  condition,  and results of
operations.

Managed Care

         Managed care arrangements  typically shift some of the economic risk of
providing  patient care from the person who pays for the care to the provider of
the care by  capping  fees,  requiring  reduced  fees,  or  paying a set fee per
patient  irrespective of the amount of care  delivered.  With respect to hearing
care, such limits could result in reduced  payments for services or restrictions
on the types of services for which  reimbursement  is available or the frequency
of replacements or upgrades of equipment.  If managed care  arrangements  become
more  prevalent  in the  hearing  care  field  in the  future,  or the  downward
pressures on fees associated with managed care increase, the Company's business,
financial  condition,  and results of  operations  may be  materially  adversely
affected.

Dependence on Key Personnel

         The success of the Company is dependent to a significant  degree on the
services  of Brandon  M.  Dawson,  president  of the  Company,  and on the other
members of its  executive  management  team.  The loss of the services of any of
these key  personnel  could  have a  material  adverse  effect on the  Company's
business, financial condition, and results of operations.


                                      - 8 -




<PAGE>




         The Company's success is also substantially  dependent upon its ability
to identify, attract and retain qualified employees,  particularly audiologists,
who are primarily responsible for clinic profitability as well as for attracting
and retaining customers. The Company recruits such personnel from a limited pool
of available applicants.  Although the Company attempts to enter into employment
contracts with its audiologists  that contain  non-competition  covenants,  such
audiologists  may become  competitors of the Company.  The Company's  failure to
attract and retain  audiologists  and other key employees  would have a material
adverse effect on the business,  financial condition,  and results of operations
of the Company.

Uncertain Ability to Manage Growth

         The  Company's  operations  to date have  principally  consisted of the
operation  of a limited  number of hearing  care  clinics  in British  Columbia,
Alberta, and more recently in Southern California,  Illinois,  Michigan, and New
Mexico. The Company's expansion plans in the United States and Canada will place
additional demands on the Company's management.  The Company has five executives
and eight other  employees  staffing  its  corporate  headquarters.  Significant
expansion could place a strain on the Company's  managerial and other resources,
including its systems and controls, and could require the Company to recruit and
hire a number of new  managerial and other  personnel.  The process of locating,
training,  and  successfully  integrating  such  personnel  into  the  Company's
operations  is  time-consuming  and costly.  There can be no assurance  that the
Company will be  successful  in  attracting,  integrating,  and  retaining  such
personnel.  A  failure  to  manage  any  expansion  effectively  or  to  provide
appropriate  administrative  support to the Company's hearing care clinics could
have a material adverse effect on the Company's business,  financial  condition,
and results of operations.

Concentration of Stock Ownership

         The executive  officers and directors of the Company  beneficially  own
approximately  7.8 million shares (not including shares subject to options),  or
41% of the Common Stock presently outstanding.  Accordingly,  these individuals,
acting in concert,  presently have substantial  influence,  if not control, over
most matters requiring shareholder approval, including the election of directors
and the approval of significant  corporate  transactions.  Such concentration of
ownership  could  also  permit  substantial  shareholders  to delay or prevent a
change  in  control  of the  Company  and  may  discourage  third  parties  from
attempting to acquire such control.

Public Market; Volatility of Stock Price

         The Common Stock is presently  traded on The Alberta Stock  Exchange in
Canada.  However, there has been no public market for the Company's Common Stock
in the United  States and there is no assurance  that an active  trading  market
will develop or be sustained.  Even if an active  trading market does develop in
the United  States,  the market  price of the  Company's  Common  Stock could be
significantly  affected  by such  factors as the  Company's  operating  results,
changes  in any  earnings  estimates  publicly  announced  by the  Company or by
analysts,  announcements  of  technological  or surgical  innovations  affecting
hearing care, the introduction


                                      - 9 -




<PAGE>



of new hearing care products or changes in existing  hearing care products,  and
various factors affecting the economy in general. In addition, the stock markets
in the  United  States  and Canada  have  experienced  a high level of price and
volume  volatility  and  market  prices  for the  stock of many  companies  have
experienced  wide price  fluctuations  not necessarily  related to the operating
performance of such companies.

Potential for Future Sales of Shares

         This  Prospectus  relates  to the  offering  for  sale  of a  total  of
25,312,814 shares of the Company's Common Stock from time to time by one or more
persons  identified  under the  caption  "Selling  Shareholders"  (the  "Selling
Shareholders"),  of which (i) 9,917,598 shares are presently  outstanding,  (ii)
13,395,216  shares are issuable upon the exercise of special warrants or related
purchase warrants,  and (iii) 2,000,000 shares are issuable upon the exercise of
convertible  notes. See "Selling  Shareholders,"  "Principal  Shareholders," and
"Plan of Distribution." An additional 4,493,630 shares of Common Stock which are
not  covered by this  Prospectus  are  issuable  upon the  exercise  of options,
purchase  warrants,  and  convertible   securities,   of  which  1,404,630  were
exercisable  at March 1,  1997.  Also,  approximately  9,840,000  shares  of the
outstanding  Common  Stock which are not covered by this  Prospectus  are freely
transferable  under the Canadian and U.S. federal  securities laws. Sales of any
significant  number of shares of Common Stock,  or the potential for such sales,
in the public market could adversely  affect the prevailing  market price of the
Common Stock. See "Price Range of Common Stock."

Possible Adverse Effects of Economic Trends

         Purchases   of   hearing   instruments   are   largely   discretionary,
particularly where third party reimbursement is not available or available as to
only  a  portion  of  hearing  care  expenses.  Accordingly,   general  economic
conditions,  particularly  those  affecting  persons on fixed  incomes,  such as
changes in the  interest  rate  environment,  levels of  taxation  or the Social
Security  system,  may have a significant  effect on the Company's  business.  A
decline  in demand for the  Company's  services  would  have a material  adverse
effect  on  the  Company's  business,   financial  condition,   and  results  of
operations.

Competition

         The market in which the  Company  operates  is  intensely  competitive,
highly  fragmented,  and  characterized  by  intense  price  competition  and an
increasing  number of new  audiologists  entering  the  market.  The Company has
numerous  competitors  in each of the markets in which it operates  hearing care
clinics. Some of its competitors are better known and have substantially greater
financial and marketing resources than the Company.  In addition,  other persons
or entities may seek to acquire hearing care clinics in the markets in which the
Company hopes to operate,  thereby creating competitive  pressures in connection
with the acquisition of hearing care clinics by the Company.

Labor Unions

          Although there are no collective  bargaining  agreements in place with
respect  to the  Company's  operations,  there  can  be no  assurance  that  the
Company's  employees  will not attempt to  unionize.  Certain  individuals  have
attempted to unionize the employees of HC Health Care Hearing  Clinics Ltd., the
Company's  Canadian operating  subsidiary,  in the past. Any unionization of the
Company's  employees  could  have a  material  adverse  effect on the  business,
financial condition, and results of operations of the Company.

Additional Financing

         The Company's  strategy to acquire additional hearing care clinics will
require substantial additional funding. Moreover, funding will be needed for the
development  of an on-line  management  information  system  that will link each
clinic with the Company's  corporate headquarters and for additional working
capital.  These  funding  requirements  may  result  in  the  Company  incurring
long-term and  short-term  indebtedness  and in the public or private  issuance,
from time to time,  of  additional  equity or debt  securities.  There can be no
assurance  that any such  financing  will be available to the Company or will be
available on terms acceptable to the Company.

Reputation of the Industry

         Certain  segments of the hearing care industry,  in particular the sale
and fitting of hearing aids, have been the subject of governmental investigation
and  adverse   publicity  due  to   unscrupulous   sales  practices  by  certain
organizations. Adverse publicity concerning the hearing care industry could have
a material adverse effect on the Company's business,  financial  condition,  and
results of operations.

Regulation

         The sale of hearing aid devices is  regulated  at the federal  level in
the United  States by the United  States Food and Drug  Administration  ("FDA"),
which has been granted  broad  authority to regulate the hearing care  industry.
Under federal law,  hearing aids may only be sold to individuals  who have first
obtained  a medical  evaluation  from a  licensed  physician,  although  a fully
informed adult may waive a medical evaluation in certain instances.  Regulations
promulgated  by the FDA also presently  require that  dispensers of hearing aids
provide customers with certain warning statements and notices in connection with
the sale of hearing aids and that such sales be made in compliance  with certain
labeling requirements.

         Most  states  in  the  United  States  and  provinces  in  Canada  have
established  formal  licensing  procedures  that  require the  certification  of
audiologists  and/or  HISs and  although  the  extent  of  regulation  varies by
jurisdiction, almost all states and provinces engage in some degree of oversight
of the  industry.  The Company has  recently  been advised that certain laws and
regulations  in the states of  California  and Illinois  may  prohibit  business
corporations such as the


                                     - 11 -




<PAGE>



Company from engaging in the practice of audiology.  These laws and regulations,
which have been subject to limited judicial and regulatory  interpretation,  are
enforced by regulatory authorities with broad discretion.  The Company is in the
process of determining  whether its business  operations are in compliance  with
such  laws  and  regulations.  No  assurance  can be given  that  the  Company's
activities  will be found to be in compliance  with such laws and regulations or
if its activities are not in compliance,  that the operational  structure of the
Company can be modified to permit compliance.  In addition,  no assurance can be
given that other  states or provinces  in which the Company  presently  operates
will not enact  prohibitions on the corporate  practice of audiology or that the
regulatory framework of certain  jurisdictions will not limit the ability of the
Company to expand into such jurisdictions if the Company is unable to modify its
operational  structure to comply with such  prohibitions or to conform with such
regulatory  framework.  Additional  laws and  regulations  may be adopted in the
future at the  federal,  state,  or  province  level  that could have a material
adverse effect on the business,  financial condition,  and results of operations
of the Company.

         A small percentage of the revenues of the hearing care clinics operated
by the Company comes from Medicare and Medicaid programs.  Federal law prohibits
the offer,  payment,  solicitation  or receipt  of any form of  remuneration  in
return  for, or in order to induce,  (i) the  referral of a Medicare or Medicaid
patient,  (ii)  the  furnishing  or  arranging  for the  furnishing  of items or
services reimbursable under Medicare or Medicaid programs or (iii) the purchase,
lease or order of any item or service  reimbursable  under Medicare or Medicaid.
Noncompliance with the federal anti-kickback legislation can result in exclusion
from Medicare and Medicaid programs and civil and criminal penalties.

Potential Issuance of Preferred Stock and Additional Common Stock

         The Board of Directors has the  authority to issue an unlimited  number
of preferred shares of the Company ("Preferred Stock") in one or more series and
to fix the  number of shares of any such  series and the  designations,  rights,
privileges,  restrictions, and conditions attaching thereto, without any further
vote or action by the  shareholders  of the  Company.  The issuance of Preferred
Stock could adversely affect the rights of holders of Common Stock. For example,
the issuance of  Preferred  Stock could result in  securities  outstanding  that
would have  preference  over the Common Stock with  respect to dividends  and in
liquidation and that could (upon conversion or otherwise) have all of the rights
of the Common Stock.  The Board of Directors  also has the authority to issue an
unlimited  number of additional  shares of Common Stock without any further vote
or action by the Company's  shareholders,  possibly causing the interests of the
existing shareholders to suffer substantial dilution.  The issuance of Preferred
Stock  or  additional  Common  Stock  could  potentially  be used to  discourage
attempts  by others to obtain  control of the  Company  through  merger,  tender
offer, proxy or consent solicitation,  or otherwise by making such attempts more
costly or more difficult to achieve.

<PAGE>



                    SERVICE AND ENFORCEMENT OF LEGAL PROCESS

         The Company is incorporated  under the laws of the Province of Alberta,
Canada. Some of the directors,  controlling persons and officers of the Company,
as well as certain of the experts named herein,  are residents of Canada and all
or a portion  of the  assets of such  persons  and of the  Company  are  located
outside of the United  States.  As a result,  it may be difficult for holders of
the Common  Stock to effect  service  within the United  States upon the Company
(although it may be possible to effect service upon the Company's  United States
subsidiary) and those directors,  controlling persons,  officers and experts who
are not residents of the United States,  or to realize in the United States upon
judgments of courts of the United  States  predicated  upon the civil  liability
provisions  of the United  States  federal  securities  laws to the extent  such
judgments  exceed  such  person's  United  States  assets.  The Company has been
advised by its Canadian counsel,  Ballem MacInnes, that there is doubt as to the
enforceability  in Canada  against the Company or against any of its  directors,
controlling  persons,  officers or experts who are not  residents  of the United
States, in original actions or in actions for enforcement of judgments of United
States  courts,  of  liabilities  predicated  solely upon United States  federal
securities laws.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

                  Certain  statements  contained in this  Prospectus,  including
without limitation  statements  containing the words "believes,"  "anticipates,"
"intends,"  "expects" and words of similar import,  constitute  "forward-looking
statements" within the meaning of the U.S. Private Securities  Litigation Reform
Act of 1995. Such  forward-looking  statements  involve known and unknown risks,
uncertainties  and other factors that may cause the actual results,  performance
or  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.  Such  factors  with  respect to the  Company
include  economic  trends in the  Company's  market  areas,  the  ability of the
Company to manage its growth and integrate new acquisitions  into its network of
hearing care clinics, changes in the application or interpretation of applicable
governmental  laws and  regulations,  the  ability of the  Company  to  complete
additional  acquisitions  of  hearing  care  clinics on terms  favorable  to the
Company, the degree of consolidation in the hearing care industry, the Company's
success in attracting and retaining qualified  audiologists and staff to operate
its hearing clinics,  product and professional  liability claims brought against
the Company that exceed the Company's insurance  coverage,  and the availability
of and costs  associated with potential  sources of financing.  Certain of these
factors are  discussed in more detail  elsewhere in this  Prospectus,  including
without limitation under the captions "Risk Factors,"  "Management's  Discussion
and Analysis of Financial  Condition and Results of Operations," and "Business."
Given these  uncertainties,  prospective  investors  are  cautioned not to place
undue reliance on such  forward-looking  statements.  The Company  disclaims any
obligation to update any such factors or to publicly  announce the result of any
revisions to any of the forward-looking  statements  contained herein to reflect
future events or developments.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

         General

         Since 1995,  the Company has achieved  significant  growth in revenues,
primarily  due to the  acquisition  and  operation  of  additional  hearing care
clinics.  For the year ended July 31, 1996,  and the three months ended  October
31, 1996, the Company generated total revenues of $2.4 million and $1.3 million,
respectively.  As of October 31,  1996,  the  Company's  cumulative  deficit was
$710,000 and its total shareholders' equity was $4.8 million. For the year ended
July 31,  1996,  and the three  months  ended  October  31,  1996,  the  Company
generated  net losses of $582,000  and  $301,000,  respectively.  On a pro forma
basis,  giving effect to the  acquisitions of Hearing Care Associates  Group and
the Midwest Division of Hearing Health Services,  Inc., dba SONUS ("SONUS"),  as
if such  acquisitions  had  occurred on August 1, 1995,  the Company  would have
generated net losses of $717,000 for the year ended July 31, 1996,  and $318,000
for the three months ended October 31, 1996.

         Revenues

         The Company  intends to  increase  its  revenues  by making  additional
acquisitions of hearing care clinics and by providing  high-quality  service and
using targeted regional  marketing at existing and newly acquired  clinics.  The
Company believes that, for the foreseeable future, the level of managed care and
third-party reimbursement will continue to be minimal and that its revenues will
be derived primarily from its private payor patient base.

         Cost of Sales and Operating Expenses

         The  Company  intends  to lower  its cost of sales as a  percentage  of
revenues  by  negotiating  improved  hearing  aid  manufacturer   discounts.  In
addition,  the  Company  expects  that  operating  expenses  will  decrease as a
percentage  of  revenues  as  revenues  increase  and  economies  of  scale  and
administrative  efficiencies are realized. However, the amortization of goodwill
resulting  from  acquisitions  will increase as more clinics are acquired by the
Company.

         The following  discussion  of the results of  operations  and financial
condition  of the  Company  should  be read in  conjunction  with the  Company's
audited and unaudited  consolidated  financial  statements and the notes thereto
contained elsewhere in this Prospectus.

Results of Operations

Three Months Ended October 31, 1996,  Compared to Three Months ended October 31,
1995

         Revenues.  Total  revenues for the three months ended October 31, 1996,
were $1,281,000,  representing a 149% increase over revenues of $514,000 for the
comparable period in 1995.  Substantially all of this increase resulted from the
acquisition of four clinics in Canada and fourteen clinics in the United States.
In contrast,  total  revenues for the three months ended October 31, 1995,  were
generated from nine clinics in Canada.

         Gross Profit. Gross profit for the three months ended October 31, 1996,
was  $788,000  or 62% of revenue  compared to $281,000 or 55% of revenue for the
comparable  period in 1995.  The  improvement  in gross  profit  percentage  was
primarily  due  to  the  Company's  access  to  greater  volume  discounts  from
manufacturers as a result of increased hearing aid purchases.

         Operating  Expenses.  Operating  expenses  for the three  months  ended
October  31,  1996,  were  $1,063,000,  representing  an  increase  of 253% over
operating  expenses  of  $301,000  for  the  comparable  period  in  1995.  As a
percentage of total revenues,  operating expenses increased to 83% for the three
months ended  October 31, 1996,  from 59% for the  comparable  period in 1995. A
substantial portion of the increase was attributable to salaries and benefits of
the Company's  new  executive  management  team and related  administrative  and
overhead expenses.

Year Ended July 31, 1996, Compared to Year Ended July 31, 1995

         Revenues.  Total revenues for the fiscal year ended July 31, 1996, were
$2,389,000,  representing  a 39% increase over  revenues of  $1,720,000  for the
prior fiscal year.  The  increase  was due to the  acquisition  in April 1995 of
Thomas H. Moore Audiology  Consultants  Ltd., which operated a hearing clinic in
Calgary,  Alberta,  the  opening  of a hearing  and  balance  testing  center in
Calgary,  Alberta, in March 1996, and the purchase of two hearing clinics in the
greater  Vancouver,  British  Columbia,  area during the third quarter of fiscal
1996. During this same period, the Company was affected by a general downturn in
the total number of hearing aids sold in the British  Columbia market area. This
drop was primarily  attributable  to policy changes  adopted in 1994 and 1995 by
third party insurers such as the Workers'  Compensation Board, the Department of
Veteran Affairs and certain  provincial  medical plans,  which extended the time
before  hearing  aids could be upgraded or replaced.  This change,  coupled with
certain marketing  restrictions relating to promoting such upgrades, is expected
to have a continued  negative effect on replacement  hearing aid sales in Canada
in the future.

         Gross Profit. Gross profit for the fiscal year ended July 31, 1996, was
$1,372,000  or 57% of revenues  compared to $947,000 or 55% of revenues  for the
prior fiscal year. The improvement in gross profit  percentage was primarily due
to higher volume discounts and improved product sales management.

<PAGE>



         Operating  Expenses.  Operating expenses for the fiscal year ended July
31,  1996,  were  $1,961,000,  representing  an increase  of 89% over  operating
expenses of  $1,038,000  for the prior  fiscal year.  As a  percentage  of total
revenues, operating expenses increased to 82% for the fiscal year ended July 31,
1996, from 60% for fiscal 1995. This increase was mainly due to (i) the addition
of public company  related costs  including  investor  relations  activities and
compliance  with  regulatory  reporting   requirements;   (ii)  increased  costs
associated  with  the  continued  integration  of the  various  hearing  clinics
acquired   since   October  1994  and  the  costs  of   negotiating   additional
acquisitions;  and  (iii)  the  addition  of  key  senior  management  personnel
beginning  in  December  1995 to  assist in  implementing  the  acquisition  and
consolidation strategy of the Company.

Liquidity and Cash Reserves

From August to December 1995, the Company financed its operations mainly through
internally  generated  funds,  borrowing  under bank  credit  arrangements,  and
advances  from  shareholders.  Since that time,  the  Company  has relied on the
issuance and sale of equity  securities to repay  shareholder  loans, open a new
balance  and  hearing  center in  Calgary,  Alberta,  fund  acquisitions,  begin
development of a management  information  system, and provide additional working
capital.

During the three months ended October 31, 1996, the Company  acquired 25 hearing
care clinics located in California,  Illinois,  and Michigan.  The  acquisitions
were funded  primarily  through  the  issuance  of common  stock  valued at $2.4
million,  the  issuance  of  convertible  subordinated  notes  in  an  aggregate
principal  amount of $2.6  million,  $635,000  in cash,  and the  assumption  of
$360,000 of debt.  In addition,  the Company  closed the Canadian  tranche of an
offering of special warrants at a price of $1.25 per special warrant, generating
gross  proceeds of $1,012,500.  See  "Description  of Capital  Stock--Warrants."
During the year ended July 31,  1996,  the Company  acquired  four  hearing care
clinics in Canada and two clinics in the United States.  The  acquisitions  were
funded  through the  issuance of a  convertible  note in the amount of $129,000,
promissory notes in the aggregate  principal amount of $77,700,  and cash in the
amount of $4,264,063.

The Company has a revolving demand loan with the Royal Bank of Canada, providing
for borrowings up to $184,300.  As of October 31, 1996, $119,700 was outstanding
against this line,  compared to $33,200 as of July 31, 1996.  Advances under the
line of credit bear  interest  at 1% above the Royal Bank of Canada  prime rate,
which was 6% at October 31, 1996.  Advances  under the revolving  line of credit
are  secured  by all the  assets of HC  HealthCare  Hearing  Clinics,  Ltd,  the
Company's Canadian operating  subsidiary,  and personally  guaranteed by Marilyn
Marshall, a shareholder.

The Company expects to spend approximately  $600,000 in fiscal 1997 to develop a
management  information  system that will link each  clinic  with the  Company's
headquarters.  Development  costs will  include  system  design,  new  hardware,
patient management and accounting software,  and staff training.  The Company is
seeking to finance a substantial portion of this cost. The Company also plans to
outsource the majority of its advertising and public relations functions


                                     - 30 -




<PAGE>



at a cost of approximately $350,000 over the next 12 months, exclusive of direct
marketing costs such as printing, mailing, and media purchases.

The Company  believes that its existing cash balances,  amounts  available under
the revolving  line of credit,  and cash from  operations  will be sufficient to
fund its  operations  and  planned  acquisitions  over the  next  three  months.
However,  to execute its long-term business  strategy,  the Company will require
additional  funding in order to acquire  new  clinics  and to expand  into other
geographic  markets.  The Company will attempt to obtain the  necessary  capital
through  additional  long-term and  short-term  borrowing  arrangements  and the
issuance of additional equity or debt securities. There can be no assurance that
any such  financing  will be  available  to the Company or will be  available on
terms acceptable to the Company.

                                    BUSINESS

Overview

         The Company,  through its  subsidiaries  HC HealthCare  Hearing Clinics
Ltd., a British Columbia  corporation,  and HealthCare Hearing Clinics,  Inc., a
Washington corporation, currently owns and operates a network of 50 hearing care
clinics in the  United  States and  Western  Canada.  The  clinics  are  located
primarily  in the  metropolitan  areas of Los  Angeles,  California;  San Diego,
California;  Chicago,  Illinois;  Lansing,  Michigan;  Albuquerque,  New Mexico;
Vancouver, British Columbia; and Calgary, Alberta. The Company intends to expand
its network of hearing care clinics by acquiring clinics in its existing as well
as new  geographic  markets.  Since October 1, 1996, the Company has acquired 33
hearing clinics.

         Each  of the  Company's  hearing  care  clinics  provides  its  hearing
impaired patients with a full range of audiological  products and services.  All
of the Company's  hearing care clinics are staffed by  audiologists,  except for
one clinic  that is  staffed by a hearing  instrument  specialist  ("HIS").  The
Company's  operating  strategy  is to provide  patients  with high  quality  and
cost-effective  hearing  care while at the same time  increasing  its  operating
margins  by  attracting  and  retaining  patients,   recruiting   qualified  and
productive  audiologists,   achieving  economies  of  scale  and  administrative
efficiencies,  and pursuing large group and managed care contracts.  The Company
believes that it is well  positioned to provide  retail  hearing  rehabilitative
services to  consumers  while  simultaneously  serving the  diagnostic  needs of
referring  physicians  and meeting the access and cost  concerns of managed care
providers and insurance companies.

Industry Background

         Professionals  and  Clinics.  Hearing  aids may be  dispensed by either
dispensing  audiologists  or HISs.  Although both  audiologists  and HISs may be
licensed  to dispense  hearing  aids,  audiologists  have  advanced  training in
audiology and hold either a masters, Ph.D. or Au.D. degree.

         Overall,  dispensing audiologists are much younger than HISs. The March
1996 issue of The Hearing Review,  a hearing  industry trade journal,  indicates
that approximately 40% of HISs in the U.S. are at least 60 years of age, 24% are
50-60  years of age,  22% are 40-50  years of age and only 15% are under age 40,
compared to 1%, 11%, 37% and 52%, respectively, for dispensing audiologists. The
Company   believes  that  many  HISs  are  facing   retirement  with  no  formal
"exit-strategy," a situation that creates an attractive  investment  opportunity
for the Company.

         The typical hearing care practice wields little  purchasing  power with
manufacturers, and must spread overhead over a relatively small revenue base. In
addition,  a typical  hearing care practice  often has  insufficient  capital to
purchase new  technologies  and lacks the systems and size  necessary to develop
economies of scale. As a result, the Company believes that dispensing


                                     - 32 -




<PAGE>



audiologists  and  HISs  will  find it  increasingly  attractive  to sell  their
practices to or affiliate with larger organizations, such as the Company.

         Another  factor  that may  favor  the  consolidation  of  hearing  care
practices is managed care. As managed care becomes more pervasive,  hearing care
professionals  will have an even  greater  need for the  information  resources,
management  expertise,  economies  of scale,  and access to  managed  care group
contracts  that larger  organizations  such as the Company may be better able to
provide. However, managed care is not presently a large part of the hearing care
market and  hearing  care  products  and  services  are likely to continue to be
provided predominantly on a private pay basis for the next several years.

         Notwithstanding  the factors  favoring  consolidation  of hearing  care
practices,  there are currently only a few multiple clinic networks operating in
more than one state or  province in the United  States or Canada  with  combined
annual revenues in excess of $5 million.

         Hearing Impaired Population. The number of persons in the United States
who have hearing loss is estimated to be approximately 28 million. Approximately
12 million American adults have tinnitus (a ringing  sensation in the ears) that
is severe enough to seek medical help.  The  percentage  of  individuals  with a
hearing loss relative to the general  population is  approximately 2 percent for
those under 18 years of age, 5 percent for those between 18 and 44 years of age,
14  percent  for those  between  45 and 64 years of age,  23  percent  for those
between 65 and 74 years of age and 32 percent for those over 75 years of age.

         The  Company  believes  that the widely  recognized  demographic  trend
toward an aging  population  will  increase the demand for hearing aid sales and
audiological services and that the demand for hearing aids that are less visible
and  for  newer  and  superior  hearing  aid  technology,  such as  digital  and
programmable  hearing aids, will also contribute to market growth.  In addition,
the Company  believes  that some  individuals  forgo hearing care because of the
stigma of aging that can be  associated  with wearing a hearing aid and that the
demand for hearing aid sales and  hearing  care  services  can be  increased  by
marketing and education designed to reduce that stigma.

         Hearing Health Care Industry Segments. The hearing health care industry
serving  patients  with  hearing  and balance  disorders  is  comprised  of four
distinct service segments:

         o    hearing  rehabilitation  services,  including the  evaluation  and
              rehabilitation  of persons with hearing  impairments  by assessing
              communicative impairment and providing amplification;

         o    advanced audio-diagnostic services, including the neuro-audiologic
              evaluation  and  non-medical  diagnosis  of  hearing  and  balance
              disorders;

         o    industrial and preventative audiological services, including noise
              level measurements, dosimetry, and hearing screenings; and

         o    otolaryngologic  services,  including  surgery  and other  medical
              treatment.



                                     - 33 -




<PAGE>



The Company's  clinics primarily provide hearing  rehabilitation  services.  The
Company has one facility,  the Rockyview  Hearing and Balance  Clinic located in
Calgary,  Alberta,  that  provides  advanced  audio-diagnostic  services and one
clinic located in San Diego, California,  that provides evaluation and treatment
for patients with tinnitus.

         Hearing   rehabilitation    services   include   the   assessment   and
rehabilitation  of persons with hearing  impairments  through the use of hearing
instruments and counseling.  Rehabilitation  services,  including  amplification
systems, are provided by audiologists and HISs. The services offered include the
diagnostic  audiological  testing,  fitting  and  dispensing  of  hearing  aids,
follow-up rehabilitative assistance, the sale of hearing aid batteries,  hearing
aid  repairs,  and the sale of swim  plugs,  custom  ear  plugs,  and  assistive
listening devices.

         Advanced   audio-diagnostic   services   include  the   assessment  and
non-medical  treatment of vestibular and balance disorders and the evaluation of
patients with specific symptoms of an auditory or vestibular disorder, including
hearing loss,  tinnitus,  and balance problems.  In order to make a differential
diagnosis of hearing disorders,  an ear, nose and throat physician may employ or
refer patients to an audiologist to conduct special  diagnostic hearing tests to
differentiate between conductive, sensory, and neural pathology. If the cause of
the hearing loss is a medical  disorder in either the nervous system (neural) or
the middle ear  (conductive),  the physician  proceeds  with medical  treatment.
However,  if a non-treatable  conductive or sensory loss is found, the physician
will generally refer the patient to an audiologist for rehabilitation.

Growth Strategy

         The Company's  growth strategy is to expand its operations  through
the selective  acquisition of hearing clinics located in existing as well as new
geographic  markets.  The Company  believes  that the  fragmented  nature of the
hearing  care  industry,  the  absence  of  industry-wide   standards,  and  the
inexperience  and limited  capital  resources of many  hearing  care  providers,
combine to provide an opportunity to build an expanding  network of hearing care
clinics  devoted to providing  high-quality  hearing health care  services.  See
"Risk Factors--Expansion Program."

         The  Company  plans to expand its network of clinics in each new market
by initially  targeting for  acquisition a significant  hearing care practice in
order to secure a solid  foundation  upon which to build a  regional  network of
audiology practices. The Company will then seek to acquire additional individual
or group  practices  in  order  to  realize  economies  of scale in  management,
marketing, and administration, and hopes that its initial purchase in the region
will attract other practitioners interested in selling their businesses.  Due to
the contacts of management  with  audiologists  in the industry,  the Company is
frequently  presented with opportunities to acquire hearing care clinics.  Since
October 1, 1996, the Company has acquired 33 clinics,  all located in the United
States.

         The Company looks at the following  factors before acquiring clinics in
a particular  geographic  market:  (a)  population  size and  distribution;  (b)
audiology practice density,


                                     - 34 -




<PAGE>



saturation and average group size; (c) local  competitors;  (d) level of managed
care penetration;  and (e) local industry and economy.  In acquiring  particular
clinics within a geographic market, the Company seeks clinics with the following
characteristics:  (a) an  established  patient base  drawing from a  substantial
metropolitan  population;  (b) significant  revenue and  profitability  prior to
acquisition;  (c) above-average  potential to enhance clinic profitability after
acquisition;  and (d) if a  clinic  has an  audiologist,  a  willingness  by the
audiologist  to enter into an employment  agreement with the Company in order to
retain continuity in patient service and relationships and maintain the identity
of the clinic in the community where it is located.

         The  Company  generally  uses cash,  Common  Stock,  promissory  notes,
assumption of debt, or a combination of the foregoing to fund acquisitions.  See
"Risk  Factors--Additional  Financing." The amount paid for each practice varies
on a case-by-case  basis according to historical  revenues,  projected  earnings
after  integration into the Company,  and transaction  structure.  In connection
with each acquisition,  the Company acquires  substantially all of the assets of
the practice,  including its audiological  equipment and supplies,  office lease
and improvements, receivables and patient files.

         At the time a practice is acquired, the audiologist associated with the
practice  typically  becomes an  employee  of the  Company  and  enters  into an
employment  agreement  with the Company  with an initial term of three years and
annual  renewals  thereafter.   The  employment  agreement  usually  includes  a
three-year  noncompete  provision  following  termination of employment.  If the
office of a retiring  HIS is  acquired,  a six- to 12-month  transition  plan is
usually  negotiated  with  the  HIS.  See  "Risk   Factors--Dependence   on  Key
Personnel."

Operating Strategy

         The Company's  operating  strategy is to provide its patients with high
quality and cost effective  hearing care products and services while at the same
time  increasing  its operating  margins by attracting  and retaining  patients,
recruiting qualified and productive  audiologists,  achieving economies of scale
and  administrative  efficiencies,  and  pursuing  large group and managed  care
contracts.


         Attracting  and  Retaining  Patients.  The Company seeks to attract new
patients and retain existing patients at each clinic by providing  patients with
friendly, comprehensive, and cost-effective hearing care at convenient times and
locations. In addition, by educating patients about hearing health issues and by
providing quality service during office visits and consistent  patient follow-up
and  support,  the Company  hopes to foster  patient  loyalty and  increase  the
likelihood of obtaining referrals and repeat visits for examinations and product
purchases. See "Risk  Factors--Competition"  and "Risk Factors--Impact of Policy
Changes by Third-Party Insurers."

         Recruiting Qualified and Productive Audiologists.  The Company seeks to
employ  audiologists  who share the Company's  goal of  delivering  high-quality
hearing care service and


                                     - 35 -




<PAGE>



who are also dedicated to expanding and enhancing their  practices.  The Company
believes that it can offer  significant  benefits to  audiologists  by providing
assistance  in  administrative  tasks  associated  with  operating  an audiology
practice,  thereby  allowing  them to focus on serving  patients and  increasing
productivity. The Company also believes that its size and structure enable it to
offer financial resources for practice development and enhancement that solo and
small group  practitioners  find  difficult to obtain  independently.  See "Risk
Factors--Dependence on Key Personnel."

         Achieving  Economies of Scale and  Administrative  Efficiencies.  A key
operating strategy of the Company is to achieve increased economies of scale and
administrative efficiencies at each of its clinics. When a clinic is acquired by
the Company, it immediately has available to it terms and discounts with hearing
aid  manufacturers  that are generally more  favorable  than it could  negotiate
independently.  In addition,  the Company believes that by centralizing  certain
management and administrative functions such as marketing, billing, collections,
human resources, risk management,  payroll, and general accounting services, the
profitability  of a  clinic  can be  improved  by  spreading  the  cost  of such
functions over a larger revenue base. The Company is also  developing an on-line
management  information  system that will link each  clinic  with the  Company's
corporate  headquarters  in order to  provide  management  with the  ability  to
collect and analyze  clinic data,  control  overhead  expenses,  allow  detailed
budgeting at the clinic level, and permit  effective  resource  management.  See
"Risk   Factors--Integration  of  Acquired  Hearing  Care  Clinics,"  and  "Risk
Factors--Ability to Manage Growth" and "Risk Factors--Additional Financing."

         Pursue  Large Group and Managed  Care  Contracts.  Although the Company
intends to continue to aggressively pursue private-payor  business because it is
presently more pervasive and profitable than managed care business,  the Company
believes  that by providing  comprehensive  geographic  coverage in a particular
market, it will be strongly positioned to offer group hearing care plans in that
market. At the present time, managed care penetration of the hearing care market
is  limited.  However,  if managed  care begins to play a larger role in hearing
care, the Company plans to develop information systems to improve  productivity,
manage complex  reimbursement  methodologies,  measure patient  satisfaction and
outcomes of care, and integrate  information  from multiple  sources.  See "Risk
Factors--Competition" and "Risk Factors--Managed Care."


Clinic Staffing and Facilities

         Typically,  each  Company  hearing  clinic is staffed with at least one
audiologist and one patient care coordinator,  who handles reception,  clerical,
and most  bookkeeping  functions.  The  Company  has only one clinic that is not
staffed by an audiologist.  Where volume warrants,  a clinic may also be staffed
with  additional  audiologists  and patient care  coordinators.  An  audiologist
employed  by the  Company  has a  masters  or Ph.D.  degree  in  audiology.  The
audiologist is licensed by the appropriate state or province to dispense hearing
aids and is a


                                     - 36 -




<PAGE>



member  of  the  Canadian   Association  of  Speech/Language   Pathologists  and
Audiologists or the American Speech Language Hearing Association.

         Each of the  Company's  hearing  clinics  operates in leased space that
ranges in size from 800 to 3,000 square feet depending on patient volume and the
extent of services  provided by the clinic.  Clinics  generally have a reception
seating area, a reception work and filing area, an office for the audiologist, a
laboratory  for hearing  instrument  repairs  and  modifications,  a  technology
demonstration  room and an evaluation room. A properly  equipped office offering
only hearing  rehabilitation  services requires  equipment that costs $50,000 to
$75,000.  The cost of equipment for a clinic offering advanced  audio-diagnostic
services is much greater and ranges from $225,000 to $250,000.

         Clinics  owned  by  the  Company   currently   employ  a  total  of  94
audiologists at the following locations:

Products and Suppliers

         The  hearing aid  manufacturing  industry  is highly  competitive  with
approximately 40 manufacturers  serving the worldwide market.  Few manufacturers
offer  significant  product  differentiation.  The Company  currently  purchases
hearing aids from a number of  manufacturers  based upon  criteria  that include
quality, price, and service. Over time, the Company intends to reduce the number
of manufacturers from whom it purchases hearing aids in order to achieve


                                     - 38 -




<PAGE>



greater volume  discounts.  In addition to hearing aids,  the Company's  clinics
also offer a limited selection of other assistive  listening devices and hearing
aid accessories.

Marketing

         The  Company's  marketing  program is designed to help its hearing care
clinics retain existing  patients and expand the services they receive,  attract
new patients, and develop contracts to serve large groups of patients.

         The Company believes that patient  satisfaction is the key to retaining
and  expanding  services to existing  patients.  The Company also  believes that
delivering  comfortable,  high quality  hearing care at times and locations that
are convenient for the patient will motivate patients to return to the Company's
clinics for their future  hearing care needs.  Educating  patients about hearing
health,  prescribing only necessary  hearing enhancing  products,  ensuring that
each  patient  leaves  a clinic  with a  future  visit  already  scheduled,  and
maintaining  consistent  patient  follow-up  and support are key elements of the
Company's plan to build patient loyalty and patronage.

         After a patient has obtained a hearing instrument, ongoing revenues are
generated from battery purchases and routine maintenance of the instruments. The
Company  believes that repeat  revenues are  attributable  to the length of time
that a  clinic  has  been  established  and  the  effectiveness  of its  patient
retention programs.

         The Company  believes that the same aspects of the  Company's  approach
that earn the loyalty of current  patients will also generate new patients.  The
Company's  new  patient  marketing  programs  are  designed  to help the Company
generate  referrals  from  physicians  and  existing  patients  and increase the
Company's  visibility  in the  community.  The  Company  seeks  to  foster  such
visibility  by  developing  marketing  materials  and  information  sources that
communicate the Company's  philosophy of high quality  patient-oriented  hearing
care.

         The Company's large group marketing  approach is designed to enable the
Company to develop contacts with self-insured employers and with health plans in
the  metropolitan  areas it serves and  emphasizes the  convenience,  quality of
care, and wide range of services offered by the Company.  The economies of scale
available to the Company may also allow health plans and self-insured  employers
served by the  Company to reduce  administrative  burdens  they might  otherwise
face. The Company  believes that it is well  positioned to respond to challenges
presented by the growth of managed care arrangements as they arise.

Competition

         The hearing  care  industry  in the United  States and Canada is highly
fragmented  and intensely  competitive.  Many of the Company's  competitors  are
small retailers that focus primarily on the sale of hearing aids.  However,  the
Company also competes with other networks of hearing care clinics and with large
distributors of hearing aids such as Bausch &


                                     - 39 -




<PAGE>



Lomb,  a hearing  aid  manufacturer  that  distributes  its  products  through a
national  network of over 1,000  franchised  stores  (Miracle  Ear), and Beltone
Electronic  Corp., a  privately-owned  hearing aid manufacturer that distributes
its products  primarily  through its  nationwide  network of  approximately  600
franchised  dealers.  These competitors are in many cases better known and owned
by companies having far greater  financial and other resources than the Company.
There can be no assurance that one or more of these competitors will not seek to
compete  directly in the markets  targeted by the Company,  nor can there be any
assurance that the largely fragmented hearing care market cannot be successfully
consolidated by other companies or through the  establishment of  co-operatives,
alliances, confederations or the like. See "Risk Factors--Competition."

Regulation

         The sale of hearing aid devices is  regulated  at the federal  level in
the United  States by the United  States Food and Drug  Administration  ("FDA"),
which has been granted  broad  authority to regulate the hearing care  industry.
Under federal law,  hearing aids may only be sold to individuals  who have first
obtained  a medical  evaluation  from a  licensed  physician,  although  a fully
informed adult may waive a medical evaluation in certain instances.  Regulations
promulgated  by the FDA also presently  require that  dispensers of hearing aids
provide customers with certain warning statements and notices in connection with
the sale of hearing aids and that such sales be made in compliance  with certain
labeling requirements.

         Most  states  in  the  United  States  and  provinces  in  Canada  have
established  formal  licensing  procedures  that  require the  certification  of
audiologists  and/or  HISs and  although  the  extent  of  regulation  varies by
jurisdiction, almost all states and provinces engage in some degree of oversight
of the  industry.  The Company has  recently  been advised that certain laws and
regulations  in the states of  California  and Illinois  may  prohibit  business
corporations  such as the Company from  engaging in the  practice of  audiology.
These laws and  regulations,  which have been  subject to limited  judicial  and
regulatory  interpretation,  are enforced by regulatory  authorities  with broad
discretion.  The Company is in the process of  determining  whether its business
operations are in compliance with such laws and regulations. No assurance can be
given that the Company's  activities will be found to be in compliance with such
laws and  regulations  or, if its  activities  are not in  compliance,  that the
operational  structure of the Company can be modified to permit  compliance.  In
addition,  no assurance can be given that other states or provinces in which the
Company presently operates will not enact prohibitions on the corporate practice
of audiology or that the regulatory framework of certain  jurisdictions will not
limit the  ability  of the  Company  to expand  into such  jurisdictions  if the
Company  is unable to  modify  its  operational  structure  to comply  with such
prohibitions or to conform with such regulatory  framework.  Additional laws and
regulations  may be adopted in the future at the  federal,  state,  or  province
level  that  could have a material  adverse  effect on the  business,  financial
condition, and results of operations of the Company.

         A small percentage of the revenues of the hearing care clinics operated
by the Company comes from Medicare and Medicaid programs.  Federal law prohibits
the offer, payment,


                                     - 40 -




<PAGE>



solicitation  or receipt of any form of  remuneration in return for, or in order
to  induce,  (i) the  referral  of a  Medicare  or  Medicaid  patient,  (ii) the
furnishing  or arranging for the  furnishing  of items or services  reimbursable
under Medicare or Medicaid programs or (iii) the purchase, lease or order of any
item or service reimbursable under Medicare or Medicaid.  Noncompliance with the
federal  anti-kickback  legislation  can result in exclusion  from  Medicare and
Medicaid programs and civil and criminal penalties.

Product and Professional Liability; Product Returns

         In the ordinary  course of its business,  the Company may be subject to
product and  professional  liability  claims alleging the failure of, or adverse
effects  claimed to have been caused by,  products sold or services  provided by
the Company. The Company maintains insurance against such claims at a level that
the Company  believes is  adequate.  A customer  may return a hearing aid to the
Company and obtain a full refund up to 30 days after the date of purchase.  Some
of the Company's clinics offer a 60-day refund period.  In general,  the Company
can  return  hearing  aids  returned  by  customers  within 30 to 60 days to the
manufacturer  for a full  refund.  The  Company  maintains  a  reserve  based on
estimated  returns to account for returns  that cannot be passed  through to the
manufacturers and must be absorbed by the Company.

Employees

         At December 31, 1996,  the Company had 146  full-time  and 35 part-time
employees,  of  which 91 were  practicing  audiologists.  None of the  Company's
employees are  represented  by a labor union.  Management  believes it maintains
good relationships with its employees. See "Risk Factors--Labor Unions."

Properties

         The Company's  principal executive offices are located in approximately
3,000 square feet of leased office space in downtown Portland, Oregon. The lease
covering  such space  expires in August 1999 and  provides for an annual rent of
$57,072.  Each of the Company's  hearing  clinics  operates in leased space that
ranges in size from 800 to 3,000 square feet.  All of the  locations  are leased
for one to six year terms  pursuant to  generally  non-cancelable  leases  (with
renewal  options in some cases).  The  aggregate  committed  rental  expense for
clinic  leases  for  the  five-year   period   beginning   August  1,  1996,  is
approximately $2.8 million.

agreement  provides Mr. Frazer with certain fringe  benefits such as medical and
dental insurance,  vacation,  professional  liability  insurance,  an automobile
allowance,  reimbursement  of certain  expenses,  and  options to purchase up to
200,000  shares of Common Stock at $1.30 per share.  Mr. Frazer also received an
additional  200,000 options to purchase Common Stock at $1.30 per share upon his
election  as a  director  of the  Company.  Mr.  Frazer's  employment  agreement
contains covenants of nonsolicitation of employees,  clients or customers of the
Company  and of  noncompetition  during his period of  employment  and for three

consulting agreement with Hugh T. Hornibrook,  a director of the Company,  under
which the Company  will pay Mr.  Hornibrook  a retainer of Cdn$100 per month and
Cdn$125 per hour for consulting services on an as-needed basis.

Option Plans

         Effective  November  18,  1993,  the board of  directors of the Company
adopted and the  shareholders  of the Company  approved a stock option plan (the
"1993 Plan") that  provides for the grant of options to officers,  directors and
key  employees in an aggregate  number  equal to 10% of the  outstanding  Common
Stock. The exercise price of options granted under the Plan may not be less than
that permitted by the ASE.  Individual  options granted may have a term of up to
five years and may cover a number of shares up to 5% of the  outstanding  Common
Stock. All options under the 1993 Plan are  non-transferable and non-assignable.
The option  agreements  vary as to  vesting,  with the  majority  providing  for
vesting in  installments.  A total of 3,475,000  options have been granted under
the 1993 Plan, of which 925,000 have been exercised,  1,975,000 are outstanding,
and 575,000 have been canceled or terminated.

         Effective  December  10,  1996,  the board of  directors of the Company
adopted a stock  award plan,  which was  amended and  restated as of February 5,
1997 (the  "1996  Plan"),  providing  for the grant of  options  covering  up to
1,500,000  shares of Common Stock.  The adoption of the 1996 Plan and the option
awards  granted  under the 1996 Plan are subject to  approval  by the  Company's
shareholders at its 1997 annual general meeting.  Options granted under the 1996
Plan may have a term of up to five years.  The option  exercise price must equal
or  exceed  100% of the fair  market  value of the  Common  Stock on the date of
grant. The board of directors has granted  incentive stock options to purchase a
total of 607,000 shares of Common Stock to eight  employees under the 1996 Plan,
subject to shareholder  approval.  The options granted vest over varying periods
of time  and  certain  options  may  become  exercisable  earlier  if  specified
production goals are met. If the 1996 Plan is approved by the shareholders,  the
board of directors  does not intend to grant any further  options under the 1993
Plan.

                              CERTAIN TRANSACTIONS



         From its  inception in 1994  through July 31, 1996,  Douglas F. Good, a
shareholder and director of the Company and its former chief executive  officer,
advanced funds to the Company for short-term  working capital and  acquisitions.
The Company paid Mr. Good  aggregate  interest of Cdn$59,114  for the three-year
period ended July 31, 1996.  As of July 31, 1996,  the total of the advances and
all accrued interest were repaid.

         HC HealthCare  Hearing Clinics Ltd., the Company's  Canadian  operating
subsidiary, maintains a revolving bank loan bearing interest at the bank's prime
rate plus 1% per annum and secured by a general security  agreement covering all
assets of the Company and the  guarantee  and  postponement  of claim of Marilyn
Marshall,  who is a shareholder  of the Company and shares the same household as
Mr. Good.

         William DeJong is a partner in the Calgary,  Alberta law firm of Ballem
MacInnes and a director of the Company. During the period from October 15, 1994,
to October 15, 1996, total fees,  disbursements and government sales tax paid to
Ballem  MacInnes by the Company for legal services was  Cdn$145,595.  Mr. DeJong
exercised  50,000  options at Cdn$.10  per share on  February  22,  1996.  Total
consideration received by the Company was Cdn$5,000.

         On October 1, 1996, the Company  acquired Hearing Care Associates Group
through the acquisition of all of the outstanding  shares of three  corporations
owned by Gregory J.  Frazer,  who was  subsequently  appointed  Vice  President,
Business  Development and a director of the Company,  his wife, Carissa Bennett,
and Jami  Tanihana  (the  "HCA  Shareholders").  The  consideration  paid by the
Company  consisted of $314,724 in cash and  2,389,536  shares of Common Stock of
which Mr.  Frazer and Ms.  Bennett  received a total of  1,470,359  shares.  Mr.
Frazer  and Ms.  Bennett  also  received  a total of  $314,724  in  payment  for
covenants not to compete.

         Twenty-five  percent,  or 597,384, of the shares of Common Stock issued
to the HCA Shareholders  are being held by the Company (the "Retained  Shares").
One share of Common Stock will be issued to the HCA  Shareholders  on a pro rata
basis from the Retained  Shares for each dollar by which net current  assets (as
defined  in the  acquisition  agreement)  of the  acquired  corporations  exceed
certain target amounts. To the extent that such net current assets do not exceed
the target amounts, the HCA Shareholders may elect to either pay the Company one
dollar or cancel one  Retained  Share for each dollar of  shortfall.  A Retained
Share is also  required  to be canceled or a dollar paid to the Company for each
dollar by which long term  liabilities  of the  acquired  corporations  exceed a
specified  amount,  or certain  accounts  receivable  remain  uncollected  after
specified time periods.

         The HCA  Shareholders  have the right,  until  September  30, 2001,  to
require the Company to redeem an  aggregate  of 15,000 of their shares of Common
Stock as of the last day of each calendar quarter at a price of $1.67 per share.
The redemption right is noncumulative and expires if not exercised as of the end
of any calendar quarter as to such quarter.  The Company also agreed to register
the shares received by the HCA Shareholders in October 1996 under the Securities
Act. Such shares are covered by this Prospectus.

                          DESCRIPTION OF CAPITAL STOCK

         The  authorized  capital stock of the Company  consists of an unlimited
number of shares of Common Stock and an unlimited  number of shares of Preferred
Stock.

Common Stock

         The Company is  authorized  to issue an  unlimited  number of shares of
Common Stock.  Holders of Common Stock are entitled to one vote per share at all
meetings of holders of the Common Stock. All shares of Common Stock rank ratably
with regard to dividends  (if and when declared by the board of directors of the
Company).  In the event of a  liquidation,  dissolution,  or  winding  up of the
Company,  holders of Common Stock are  entitled to share  equally and ratably in
the  assets  of  the  Company,  if  any,  remaining  after  the  payment  of all
liabilities  of the Company and the  liquidation  preference of any  outstanding
class or series  of  Preferred  Stock.  The  holders  of  Common  Stock  have no
preemptive rights under Alberta law or the Company's Articles of Incorporation.



                                     - 52 -




<PAGE>



         At March 1, 1997,  19,222,336  shares of Common  Stock were  issued and
outstanding  and were  fully paid and  non-assessable,  with  5,250,000  of such
shares subject to escrow  provisions  (see  "-Escrowed  Shares").  An additional
1,873,250 shares of Common Stock are issuable without  additional  consideration
in connection with the Company's  special  warrants that were issued in February
1996 (the "February  Special  Warrants"),  and 5,467,410  shares of Common Stock
will be  issuable  without  additional  consideration  upon the  exercise of the
Company's  special warrants that were issued in September 1996 and December 1996
(together, the "September Special Warrants"). In addition,  1,873,250 shares are
issuable upon the exercise of share purchase  warrants  issued upon the exercise
or deemed  exercise of the  February  Special  Warrants at an exercise  price of
Cdn$1.50  per share until  February  28,  1998 (the  "February  Warrants"),  and
5,467,410  shares will be issuable upon the exercise of share purchase  warrants
to be issued upon the  exercise  or deemed  exercise  of the  September  Special
Warrants  at a price of $2.00 per share until  August 31,  1998 (the  "September
Warrants").  If the closing bid for the  Company's  Common Stock is in excess of
$3.00 per share on each of 20 consecutive  trading days (as traded on the ASE or
another  more senior North  American  stock  exchange)  after the day on which a
receipt is issued for the prospectus for the September  Special Warrants and all
deficiencies  are cleared by the  securities  commissions in Alberta and British
Columbia,  the Company has the option, upon 45 days' prior written notice to the
holders, to force the exercise or cancellation of the September Warrants.

         In connection with certain  acquisitions  made by the Company,  136,200
shares  of Common  Stock are  issuable  pursuant  to the terms of a  convertible
promissory  note due  September  1, 1997,  and  2,000,000  shares  are  issuable
pursuant to convertible  subordinated  notes due October 31, 1997. Up to 576,900
shares of Common  Stock will be issuable at a price of $1.25 per share  pursuant
to share  purchase  warrants  to be issued by the  Company  that will  expire on
August 31,  1998.  Upon the  acceptance  for listing or  quotation of the Common
Stock on a recognized  stock  exchange or national  trading market in the United
States,  the Company will have the option upon 45 days' prior written  notice to
force the  exercise or  cancellation  of the warrants if the closing bid for the
Common Stock is at least $3.00 per share on each of 20 consecutive trading days.
In addition,  an  aggregate  of 2.6 million  shares of Common Stock are issuable
upon the  exercise  of stock  options  granted  to the  Company's  officers,
employees and directors.

         The Board of  Directors  may issue an  unlimited  number of  additional
shares of Common  Stock  without  any  further  vote or action by the  Company's
shareholders,  which may cause the interests of existing  shareholders to suffer
substantial dilution. See "Risk  Factors--Potential  Issuance of Preferred Stock
and Additional Common Stock."

Preferred Stock

         The Company is  authorized  to issue an  unlimited  number of shares of
Preferred  Stock.  The board of directors has the  authority to issue  Preferred
Stock in one or more series and to fix the number of shares  comprising any such
series and the designations,  rights, privileges,  restrictions,  and conditions
attaching thereto, including the rate or amount of dividends or the


                                     - 53 -




<PAGE>



method  of  calculating  dividends,  the  dates of  payment  of  dividends,  the
redemption,  purchase,  and/or  conversion  price or  prices  and the  terms and
conditions of any such redemption,  purchase, and/or conversion, and any sinking
fund or other provisions, without any further vote or action by the shareholders
of the Company.  The issuance of Preferred Stock by the board of directors could
adversely  affect the voting power and other rights of holders of Common  Stock.
For  example,  the  issuance  of  shares  of  Preferred  Stock  could  result in
securities  outstanding  that would have  preference  over the Common Stock with
respect to dividends  and upon  liquidation  and that could (upon  conversion or
otherwise) enjoy all of the rights of the Common Stock.

         The  authority  possessed by the board of directors to issue  Preferred
Stock  could  potentially  be used to  discourage  attempts  by others to obtain
control  of  the  Company  through  merger,   tender  offer,  proxy  or  consent
solicitation  or otherwise by making such attempts more costly or more difficult
to  achieve.  There are no  agreements  or  understandings  for the  issuance of
Preferred  Stock,  and the Company has no plans to issue any shares of Preferred
Stock. See "Risk  Factors--Potential  Issuance of Preferred Stock and Additional
Common Stock."

Warrants

         At March 1,  1997,  the  Company  had  outstanding  1,873,250  February
Warrants governed by an indenture dated February 28, 1996 (the "February Warrant
Indenture"),  between  the  Company  and The R-M Trust  Company,  as trustee and
warrant agent (the "Trustee"). Each February Warrant entitles the holder thereof
to purchase one share of Common Stock at an exercise price of Cdn$1.50 per share
until February 28, 1998.

         At March 1, 1997,  the  Company  had  outstanding  5,386,410  September
Special  Warrants  issued pursuant to a special  warrant  indenture  between the
Company and the Trustee dated September 17, 1996 (the "September Special Warrant
Indenture").  Each of 4,576,410 of such September  Special Warrants entitles the
holder thereof to acquire, upon the exercise or deemed exercise thereof, with no
additional consideration, one share of Common Stock and one September Warrant at
any time  until the  earlier of (i) five days from the date of  issuance  by the
securities commission in each of Alberta and British Columbia of a receipt for a
prospectus of the Company in relation to the September  Special Warrants or (ii)
one year  following  the date on which the  Company  issues a  certificate  to a
subscriber in respect of the September Special Warrants subscribed for under the
September Special Warrant  Indenture (the "September Expiry Time").  Each of the
remaining  810,000  September  Special  Warrants  entitles the holder thereof to
acquire,  upon the  exercise  or deemed  exercise  thereof,  with no  additional
consideration, 1.1 shares of Common Stock and 1.1 September Warrants at any time
until the September  Expiry Time. Any September  Special  Warrants that have not
been  exercised  prior to the September  Expiry Time will be deemed to have been
exercised at the September Expiry Time without any further action on the part of
the  holder.  In the event that a receipt  for a  prospectus  for the  September
Special  Warrants is not issued in each of Alberta  and  British  Columbia on or
before April 8, 1997,  holders of September Special Warrants  currently entitled
to receive one share of Common Stock and one September  Warrant will, after such
date, be entitled to receive upon the


                                     - 54 -




<PAGE>



exercise or deemed  exercise of each September  Special  Warrant,  1.1 shares of
Common Stock and 1.1 September Warrants.

         The  September  Warrants will be issued to the holders of the September
Special  Warrants  upon the  exercise  or deemed  exercise  thereof  and will be
subject  to an  indenture  dated  September  17,  1996 (the  "September  Warrant
Indenture"),  between the Company and the Trustee, as trustee and warrant agent.
Each September  Warrant entitles the holder to subscribe for one share of Common
Stock of the  Company  at a  subscription  price of  US$2.00  until  the  expiry
thereof.  The September  Warrants will expire on August 31, 1998. If the closing
bid for the Company's Common Stock is in excess of $3.00 per share on each of 20
consecutive  trading  days (as traded on the ASE or another  more  senior  North
American  stock  exchange)  after the day on which a receipt  is issued  for the
prospectus for the September  Special  Warrants and all deficiencies are cleared
by the securities  commissions in Alberta and British Columbia,  the Company has
the option,  upon 45 days' prior  written  notice to the  holders,  to force the
exercise or cancellation of the September Warrants.

         The February  Warrant  Indenture and September  Warrant  Indenture each
provides that the exercise price per share of Common Stock thereunder is subject
to  adjustment   under  certain   circumstances,   including  any   subdivision,
consolidation,  or reclassification of the Common Stock or any reorganization of
the Company including amalgamation, merger, or arrangement.

         To the extent that a holder of a February Warrant or September  Warrant
is entitled to purchase a fraction of a share of Common Stock, such right may be
exercised only in combination  with other rights which in the aggregate  entitle
the holder to purchase a whole number of shares of Common Stock. Holders of such
warrants are not entitled to any cash payment or other  compensation  in respect
of fractional  entitlements.  Holders of such warrants do not have any voting or
preemptive rights or any other rights as shareholders of the Company.

         In connection with the placement of the September Special Warrants, the
Company has agreed to issue  576,900  share  purchase  warrants each of which is
exercisable  for one share of  Common  Stock at an  exercise  price of $1.25 per
share until August 31,  1998.  Upon  acceptance  for listing or quotation of the
Common Stock on a recognized  stock  exchange or national  trading market in the
United  States,  the Company  will have the option  upon 45 days' prior  written
notice to force the exercise or  cancellation of the warrants if the closing bid
for the  Common  Stock is at least  $3.00  per  share on each of 20  consecutive
trading days.

         The Company agreed to register the shares issuable upon exercise of the
September  Special  Warrants,  September  Warrants,  and related share  purchase
warrants under the Securities Act. Such shares are covered by this Prospectus.

Escrowed Shares

         Pursuant to certain  requirements of the Alberta securities  commission
(the "ASC") and the ASE,  certain  shares of Common  Stock are subject to escrow
agreements entered into by the Company and various shareholders.

         Under the terms of an escrow  agreement  dated January 14, 1994,  among
the Company,  the Trustee,  and certain  shareholders of the Company,  3,000,000
shares of Common Stock were  deposited  in escrow with the Trustee.  Two million
shares have been released from escrow and the last 1,000,000  shares are subject
to release on October 21, 1997,  upon  application to the executive  director of
the ASC.

         Douglas  F.  Good,  Marilyn  E.  Marshall,  and  Trudy  McCaffery  (the
"Original Shareholders"),  the Company, and the Trustee are parties to an escrow
agreement  dated  October 7, 1994 (the  "Performance  Escrow  Agreement"),  with
respect to 4,250,000 shares of Common Stock (the "Performance Shares") that were
issued to the Original Shareholders in connection with the Company's acquisition
of Fraserview  Hearing & Speech Clinic Ltd. The terms of the Performance  Escrow
Agreement  specify  that one share of Common  Stock is eligible for release from
escrow,  upon application to the ASE, for each Cdn$0.11 of "cash flow" generated
by the Company. For purposes of the Performance Escrow Agreement, "cash flow" is
defined as the Company's net income as shown on the Company's  audited financial
statements,  plus depreciation,  depletion,  deferred taxes, and amortization of
goodwill and research  and  development  costs.  All of the  Performance  Shares
remain subject to the Performance Escrow Agreement.

         Pursuant  to  a  purchase  and  sale  agreement  (the  "Share  Purchase
Agreement")  dated as of April 15, 1996,  between the Original  Shareholders and
Brandon M. Dawson, Roger W. Larose, Randall E. Drullinger and Hugh T. Hornibrook
(the "Purchasers"), the Original Shareholders sold all of the Performance Shares
to the Purchasers for an aggregate consideration of Cdn$816,000.  Pursuant to an
assignment and novation  agreement dated as of August 28, 1996,  Roger W. Larose
agreed to assign  all of his right,  title and  interest  in the Share  Purchase
Agreement  to  Brandon  M.  Dawson,  thereby  giving  Mr.  Dawson an  additional
1,900,000  shares of Common Stock.  In addition,  pursuant to an assignment  and
novation  agreement  dated as of February 27,  1997,  Mr.  Hornibrook  agreed to
assign all of his right,  title, and interest in the Share Purchase Agreement to
Edwin J. Kawasaki,  thereby giving Mr. Kawasaki  100,000 shares of Common Stock.
The assignments are subject to the approval of the ASE.

                                CANADIAN TAXATION

                  The  following is a summary of the principal  Canadian  income
tax  considerations  generally  applicable  to  nonresidents  of Canada who hold
Common Stock as capital  property,  deal at arm's length with the Company and do
not use or hold and are  deemed  not to use or hold  their  Common  Stock in the
course of  carrying  on a business  in Canada  and do not carry on an  insurance
business in Canada. This summary has been prepared by reference to the existing


                                     - 56 -

provisions  of  the  Income  Tax  Act  (Canada)  (the  "Act"),  the  Income  Tax
Regulations (the  "Regulations"),  all published  proposals for the amendment of
the Act and the Regulations to the date hereof and the published  administrative
practices of Revenue Canada,  the agency that administers the Act. Although this
summary does not specifically  address the provincial income tax consequences of
an investment in Common Stock, generally speaking,  provincial taxation does not
apply to  persons  who are not  resident  in  Canada  and who do not own or hold
property in the course of carrying on a business in Canada.  Apart from  changes
to the Act and the  Regulations  which have been publicly  announced to the date
hereof,  this summary does not consider the potential for any future alterations
to Canadian income tax legislation.

Dispositions of Common Shares

         A  nonresident  of Canada  will only be subject to  taxation  in Canada
under  the Act in  respect  of a  disposition  of  Common  Stock if such  shares
constitute  "taxable Canadian  property" to such nonresident.  Provided that the
Common Stock is listed on a recognized stock exchange in Canada at the time of a
disposition,  they will only constitute  "taxable Canadian property" to a holder
if the holder,  either alone or together  with persons with whom the holder does
not deal at arm's  length,  owns or at any time in the five  years  prior to the
date of  disposition,  has owned in excess of 25% of the issued and  outstanding
shares of a class or series  of the  capital  of the  Company.  Persons  who are
related by blood or marriage or are subject to common control are deemed to deal
otherwise  than at arm's  length;  other  persons may also be  considered  to be
dealing  otherwise  than at  arm's  length  in  certain  circumstances.  For the
purposes of determining  the 25% threshold,  rights or options to acquire Common
Stock will be treated as  ownership  thereof.  Subject to the  comments  set out
below in respect of the  application  of the U.S. - Canada Income Tax Convention
(the   "Convention")  to  U.S.  resident  holders,   nonresidents  whose  shares
constitute  "taxable  Canadian  property" will be subject to taxation thereon on
the same basis as Canadian residents. Generally speaking,  three-quarters of the
excess of the holder's  proceeds of disposition  over the adjusted cost basis of
the Common  Stock,  must be included in income as a taxable  capital gain, to be
taxed at prevailing  federal Canadian rates,  which range from approximately 25%
to 39%.

         Nonresidents  whose shares are  repurchased  by the Company,  except in
respect of certain  purchases made by the Company in the open market,  will give
rise to the deemed  payment of a dividend by the Company to the former holder of
Common Stock in an amount  equal to the excess paid over the paid-up  capital of
the Common Stock so repurchased.  Such deemed dividend will be excluded from the
former holder's  proceeds of disposition of his Common Stock for the purposes of
computing  any  capital  gain  but  will  be  subject  to  Canadian  nonresident
withholding  tax in the manner  described  below under  "Dividends."  In certain
limited  circumstances,  a sale by a holder of the Common Stock to a corporation
resident in Canada with which the holder does not deal at arm's  length may give
rise to the deemed payment of a dividend,  to the extent the amount  received in
consideration  therefor exceeds the paid-up capital of the Common Stock disposed
of.

         Pursuant  to the  Convention,  shareholders  of  the  Company  who  are
resident in the U.S. for the purposes of the  Convention  and whose shares might
otherwise be "taxable Canadian property" may be exempt from Canadian taxation in
respect of any gains on the Common  Stock  provided the  principal  value of the
Company is not derived from real  property  located in Canada at the time of the
disposition.

Dividends

         Under the Act,  withholding  tax is  imposed  at the rate of 25% on the
amount of any  dividends  paid or credited  on the Common  Stock to a person not
resident  in  Canada.  Pursuant  to the  Convention,  the  rate  of tax on  such
dividends is reduced to 6% for  dividends  received in 1996 and 5% thereafter by
any U.S. resident  corporation who owns in excess of 10% of the voting shares of
the corporation, and to 15% in all other instances.

                              INVESTMENT CANADA ACT

         The  Investment  Canada Act (the "ICA")  prohibits the  acquisition  of
control of a Canadian  business by non-Canadians  without review and approval of
the Investment  Review Division of Industry Canada,  the agency that administers
the ICA,  unless such  acquisition is exempt from review under the provisions of
the ICA. The Investment  Review  Division of Industry Canada must be notified of
such exempt  acquisitions.  The ICA covers  acquisitions of control of corporate
enterprises,  whether by purchase of assets,  shares or "voting interests" of an
entity that  controls,  directly or  indirectly,  another  entity  carrying on a
Canadian  business.  The ICA will have no effect  on the  acquisition  of shares
covered by this Prospectus.

                  Apart  from the ICA,  there  are no other  limitations  on the
right of  nonresident or foreign  owners to hold or vote  securities  imposed by
Canadian  law or the  Company's  Articles of  Incorporation.  There are no other
decrees or  regulations in Canada that restrict the export or import of capital,
including foreign exchange controls, or that affect the remittance of dividends,
interest or other payments to nonresident holders of the Company's Common Stock,
except as discussed elsewhere herein.


                              PLAN OF DISTRIBUTION

         The shares  offered hereby may be offered and sold from time to time by
the  Selling  Shareholders,   or  by  pledgees,  donees,  transferees  or  other
successors  in interest.  Such offers and sales may be made from time to time at
prices and on terms then  prevailing  or at prices  related to the  then-current
market price,  or in negotiated  transactions.  The methods by which such shares
may be sold may include, but not be limited to, the following: (a) a block trade
in which the  broker or dealer so  engaged  will  attempt  to sell the shares as
agent but may  position  and  resell a  portion  of the  block as  principal  to
facilitate the transaction; (b) purchases by a broker or dealer as principal and
resale by such broker or dealer for its account; (c) an exchange distribution in
accordance with the rules of such exchange; (d) ordinary brokerage transactions


                                     - 58 -




<PAGE>



and  transactions  in  which  the  broker  solicits  purchasers;  (e)  privately
negotiated  transactions;  (f) short sales;  and (g) a  combination  of any such
methods of sale. In effecting  sales,  brokers or dealers engaged by the Selling
Shareholders may receive commissions or discounts from the Selling  Shareholders
or from the  purchasers  in amounts to be  negotiated  immediately  prior to the
sale. The Selling  Shareholders may also sell shares in accordance with Rule 144
under the Securities Act. The Company reserves the right to suspend transfers of
the shares  offered hereby if, in its reasonable  judgment,  such  suspension is
necessary  to ensure that all  material  information  about the Company has been
properly disseminated to the public.

         The Company has advised each Selling Shareholder that he or she and any
such brokers,  dealers or agents who effect a sale of the shares  offered hereby
are subject to the prospectus  delivery  requirements  under the Securities Act.
The Company  also had advised each  Selling  Shareholder  that in the event of a
"distribution" of his shares, such Selling Shareholder and any broker, dealer or
agent  who  participates  in such  distribution  may be  subject  to  applicable
provisions of the Securities  Exchange Act of 1934 and the rules and regulations
thereunder,  including without limitation, the anti-manipulation rules under the
Securities Exchange Act of 1934.

         The Selling  Shareholders  and any brokers  participating in such sales
may be deemed to be underwriters within the meaning of the Securities Act. There
can be no assurance  that the Selling  Shareholders  will sell any or all of the
shares offered hereby.

         The  Company  has agreed to  register  the  shares of  certain  Selling
Shareholders under the Securities Act pursuant to various agreements, and all of
such shares are covered by this Prospectus. The Company is bearing substantially
all of the costs  relating to the  registration  of the shares  offered  hereby,
except  commissions,  discounts  or other  fees  payable  to a  broker,  dealer,
underwriter,  agent or market maker in  connection  with the sale of any of such
shares and the legal fees  incurred  by the Selling  Shareholders,  all of which
will be borne by the Selling  Shareholders.  The Company will not receive any of
the proceeds from the sale of the shares offered hereby.

         Any  commission  paid or any  discounts or  concessions  allowed to any
broker,  dealer,  underwriter,  agent or market  maker and, if any such  broker,
dealer,  underwriter,  agent or market maker purchases any of the shares offered
hereby as principal,  any profits received on the resale of such shares,  may be
deemed to be underwriting commissions or discounts under the Securities Act.

                                  LEGAL MATTERS

         The legality of the shares  offered hereby has been passed upon for the
Company by Ballem  MacInnes,  Calgary,  Alberta.  William  DeJong,  a partner in
Ballem MacInnes, is a director of the Company.

                                     EXPERTS

         The  consolidated  financial  statements  of the Company as of July 31,
1996, and 1995, and for each of the years in the two-year  period ended July 31,
1996,  have been  included in this  Prospectus  in  reliance  upon the report of
Shikaze Ralston, Chartered Accountants,  appearing elsewhere herein and upon the
authority of such firm as experts in accounting and auditing.

         The financial  statements of Hearing Care  Associates  Group as of July
31, 1996, and for each of the years in the two-year  period ended July 31, 1996,
and the financial statements of the Midwest Division of Hearing Health Services,
Inc., dba SONUS,  as of June 30, 1996, and for each of the years in the two-year
period ended June 30, 1996,  have been  included in this  Prospectus in reliance
upon  the  reports  of KPMG  Peat  Marwick  LLP,  independent  certified  public
accountants,  appearing  elsewhere herein and upon the authority of said firm as
experts in accounting and auditing.

         Effective  December 20, 1996, upon the  recommendation  of the board of
directors  and  approval by the  shareholders,  the Company  retained  KPMG Peat
Marwick LLP as its independent auditors,  replacing Shikaze Ralston. The Company
made the change in  independent  auditors  due to its  significant  and  growing
operations  in the  United  States  and its need to draw upon the  services  and
expertise of a large  international  accounting and auditing firm. The report of
Shikaze Ralston on the consolidated financial statements of the Company referred
to above does not contain an adverse opinion or disclaimer of opinion and is not
qualified as to uncertainty, audit scope, or accounting principles. In addition,
there were no  disagreements  with Shikaze  Ralston on any matter of  accounting
principles or practices,  financial statement  disclosure,  or auditing scope or
procedure,  which disagreements,  if not resolved to the satisfaction of Shikaze
Ralston,  would have caused them to make  reference to the subject matter of the
disagreements in connection with their report. Before engaging KPMG Peat Marwick
LLP as its new independent  certified  public  accountants,  the Company did not
consult with them regarding any matters related to the application of accounting
principles,  the type of audit  opinion that might be rendered on the  Company's
financial statements or any other such matters.

                             ADDITIONAL INFORMATION

         The  Company  is  not  currently  subject  to  the  periodic  reporting

                                AUDITORS' REPORT



To the Shareholders of
HealthCare Capital Corp.

We have audited the consolidated balance sheet of HealthCare Capital Corp. as at
July 31,  1996,  and the  consolidated  statements  of  operations  and retained
earnings  (deficit)  and changes in cash  position  for the years ended July 31,
1996  and  1995.  These  financial  statements  are  the  responsibility  of the
company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we 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 our opinion,  these consolidated  financial statements present fairly, in all
material respects, the financial position of the company as at July 31, 1996 and
the results of its operations and the changes in its cash position for the years
ended July 31, 1996 and 1995 in accordance  with generally  accepted  accounting
principles as adopted in the United States of America.

      results of  operations  of  HealthCare  Capital  Corp.  and its 100% owned
      Canadian subsidiaries, HC HealthCare Hearing Clinics Ltd., Pacific Hearing
      Clinics  Inc.  and  Oakridge   Hearing   Clinics  Inc.,   and  its  U.S.A.
      subsidiaries  Hearing Clinics,  Inc.,  Hearing Care Associates - Glendale,

4.    Significant Accounting Policies

      a)   Inventory

           Inventory is recorded at the lower of cost or net realizable value.

      b)   Capital Assets

           Capital  assets  are  recorded  at  cost  and  are  amortized  in the
following manner:

      Audiology equipment                     20% Declining  balance
      Office equipment                        20% Declining  balance
      Computer equipment                      30%  Declining  balance
      Leasehold improvements                  Straight line over five years
      Computer software                       30% Declining balance

           In the year of acquisition, amortization is calculated at one-half of
the above-noted rates.

      c)   Names, Patient Files, Reputations and Covenants Not To Compete

           The  amounts  paid  for the  names,  patient  files  and  reputations
           acquired are  equivalent to the purchase price over the fair value of
           identifiable net assets acquired, as determined by management.  These
           costs are  amortized  over 40 years using the  straight  line method.
           Covenants   not  to   compete   represent   amounts   prepaid   under
           non-competition  agreements with certain key management  personnel of
           acquired  operations.  These costs are  amortized  using the straight
           line method over the life of each agreement.

      d)   Trademarks

           Trademarks  are  amortized  over 40 years  using  the  straight  line
           method.

      e)   Deferred Acquisition Costs

           Costs  related to the  acquisition  of clinics are deferred and, upon
           successful  completion of  acquisitions,  are allocated to the assets
           acquired and are subject to the accounting policies outlined above.

      f)   Deferred Financing Costs

           Costs related to issuing  shares are  deferred.  Upon the issuance of
           the related shares,  the deferred costs are applied to reduce the net
           proceeds of the issue.

a)    Business Acquisitions

      FHC, Inc. doing business as "Family Hearing Centers"

      On December 17, 1996,  HealthCare  Hearing Clinics,  Inc. acquired all the
      outstanding  shares of FHC,  Inc.,  a New Mexico  corporation.  FHC,  Inc.
      operates one clinic in  Albuquerque,  New Mexico.  Consideration  for this
      acquisition was $250,000 in cash paid on closing and three year promissory
      notes for $150,000 bearing interest at 9% per annum.

      Hearing Dynamics, Inc.

      On December 6, 1996,  HealthCare Hearing Clinics, Inc. merged with Hearing
      Dynamic,  Inc.  ("HDI") a California  corporation.  The merger of HDI into
      Hearing Clinics,  Inc. was consummated as a tax-free merger whereby shares
      of the Company were exchanged for all the issued and outstanding shares of
      HDI. HDI  operates 3 hearing  clinics in the San Diego,  California  area.
      Consideration  for this  acquisition  was $102,600 in cash paid on closing
      and 408,000 common shares of the Company.

      The purchase price of all  acquisitions  are subject to adjustment  should
      the actual  amount of net current  assets  acquired as of the closing date
      vary from the agreed amounts.


b)    Share Capital

      The Company  entered into an Agency  Agreement on August 22, 1996 to offer
      for sale on a best efforts basis 4,800,000 September Special Warrants at a
      price of $1.25 per  September  Special  Warrant.  Each  September  Special
      Warrant will entitle the holder to acquire upon  exercise one common share
      and one September  Warrant.  Each September Warrant is exercisable for one
      common  share at a price of $2.00 until  August 31,  1998,  subject to the
      right of the Company,  upon satisfaction of certain  conditions,  to force
      early exercise or cancellation.

      Costs of the  issue  payable  to the  agents  under the  Agency  Agreement
      include a $36,855  corporate finance fee, a syndication fee equal to 1% of
      the proceeds raised payable  in cash or September  Special  Warrants and a
      commission equal to 9% of the subscriptions proceeds actually raised.

      In addition,  the agents will receive a special  option  entitling them to
      acquire purchase  warrants equal to 10% of the number of September Special
      Warrants sold,  each of which will be exercisable  for one common share of
      the Company at a price of $1.25 until August 31, 1998,  subject to certain
      rights of the Company to force early exercise or cancellation.

                          Notes to Financial Statements

                                  July 31, 1996




(1) ORGANIZATION AND OPERATIONS

    Hearing  Care  Associates  Group (the  "Company")  consists of Hearing  Care
    Associates - Northridge, Inc., Hearing Care Associates - Glendale, Inc., and
    Hearing  Care   Associates   -  Glendora,   Inc.,   and   provides   hearing
    rehabilitation  services  through a network  of  clinics  located in the Los
    Angeles,  California,   metropolitan  area.  Each  entity  is  a  California
    corporation.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   (a) CASH AND CASH EQUIVALENTS

      For purposes of reporting cash flows,  cash and cash  equivalents  include
      cash on hand and  short-term  investments  with original  maturities of 90
      days or less.

   (b) NET REVENUES

      Revenues from the sale of hearing aid products are  recognized at the time
      of  delivery.  Revenues  from the  provision  of hearing  care  diagnostic
      services are recognized at the time that such services are performed.

   (c) EQUIPMENT AND FIXTURES

      Equipment and fixtures  are stated at cost less  accumulated  depreciation
      and   amortization.   Additions  and  betterments  are  capitalized,   and
      maintenance and repairs are charged to current operations as incurred. The
      cost  of  assets  retired  or  otherwise   disposed  of  and  the  related
      accumulated  depreciation  and amortization are removed from the accounts,
      and  the  gain  or  loss on such  dispositions  is  reflected  in  current
      operations.  Amortization  of  leasehold  improvements  is  provided on an
      accelerated  basis over the term of the lease or estimated useful lives of
      the assets,  whichever is less. Depreciation is provided on an accelerated
      basis. Estimated useful lives of the assets are:

             Professional equipment                                 7 - 10 years
             Furniture and fixtures                                 7 - 10 years
             Office equipment                                        5 - 7 years
             Leasehold improvements                                      7 years

   (d) INCOME TAXES

       The  Company  accounts  for income  taxes  under the asset and  liability
       method.  Under the asset and  liability  method,  deferred tax assets and
       liabilities are recognized for the future tax  consequences  attributable
       to  differences  between  the  financial  statement  carrying  amounts of
       existing  assets  and  liabilities  and  their  respective  tax bases and
       operating  loss and tax  credit  carryforwards.  Deferred  tax assets and
       liabilities  are measured  using  enacted tax rates  expected to apply to
       taxable  income in the years in which  those  temporary  differences  are
       expected to be  recovered  or settled.  The effect on deferred tax assets

                          Notes to Financial Statements




   (e) INTANGIBLE ASSETS

      Intangible  assets consist of non-compete  agreements,  purchased  patient
      listings  and  goodwill  (the cost in excess of net assets  acquired  in a
      purchase tranasaction).  Goodwill and patient listings are being amortized
      on a  straight-line  basis  over  15  years.  Non-compete  agreements  are
      amortized on a straight-line basis over the life of the contract.

   (f) CONCENTRATIONS OF CREDIT RISK

      Financial   instruments,   which   potentially   subject  the  Company  to
      concentration  of  credit  risk,  consist  principally  of cash and  trade
      receivables.  The  Company  places  its  cash  with  high  credit  quality
      institutions. At times such amounts may be in excess of the FDIC insurance
      limits. The Company's trade accounts  receivable are derived from numerous
      private payors,  insurance carriers, health maintenance  organizations and
      government  agencies.  Concentration  of  credit  risk  relating  to trade
      accounts receivable is limited due to the diversity and number of patients
      and payors.

   (g) FAIR VALUE OF FINANCIAL INSTRUMENTS

      The  carrying  value  of  financial  instruments  such  as cash  and  cash
      equivalents, trade receivables, notes receivable, trade payables and notes
      payable, approximate their fair value.

   (h) USE OF ESTIMATES

      Management of the Company has made a number of estimates  and  assumptions
      relating to the reporting of assets and  liabilities and the disclosure of
      contingent assets and liabilities to prepare these financial statements in
      conformity with generally accepted accounting  principles.  Actual results
      could differ from those estimates.

(3) EQUIPMENT AND FIXTURES

    Equipment and fixtures consist of the following at July 31, 1996:

        Professional equipment                              $  254,431
        Office equipment                                       193,736

    The components of the 1996 and 1995 provision (benefit) for income taxes are
    as follows:

          State                            8,535         (5,402)

                                          54,000        (34,178)
                                        --------       --------

             Total                      $(22,900)      $108,883
                                        ========       ========

    At July 31, 1995,  the  difference  between the total income tax expense and
    the income tax expense computed using the statutory  federal income tax rate
    was due primarily to state tax expense,  net of federal tax benefit. At July
    31, 1996, the difference between the total income tax benefit and the income
    tax benefit  computed  using the statutory  federal  income tax rate was due
    primarily  to  state  tax  benefit,  net of  federal  effect,  as well as an
    increase in the  valuation  allowance.

    The net deferred tax asset of $20,600 at July 31, 1996,  consists  primarily
    of net operating loss  carryovers and  differences  resulting from using the
    cash method of accounting  for income tax purposes.  No valuation  allowance
    was  deemed  necessary  at July  31,  1995.  An  increase  in the  valuation
    allowance during the year resulted in a valuation allowance at July 31, 1996
    of approximately $156,000.

    At July 31, 1996,  the Company has a net  operating  loss  carryforward  for
    federal income tax purposes of approximately $274,000.


                                                                     (Continued)

                         THE MIDWEST DIVISION OF HEARING
                         HEALTH SERVICES, INC. dba SONUS

                          Notes to Financial Statements

                                  June 30, 1996




(1) ORGANIZATION AND OPERATIONS

    The  Midwest  Division  of  Hearing  Health  Services,  Inc.  dba Sonus (the
    Company) consists of the Michigan and Illinois  operations of Hearing Health
    Services,  Inc., which was organized under the laws of the State of Delaware
    on February 19, 1991 for the purpose of providing diagnostic, rehabilitation
    and  preventative  hearing  health care  products  and services to patients.
    Certain  investment  partnerships  managed by Foster  Management,  a related
    party and major stockholder, own a controlling interest in the Company.

    Prior to July 11,  1991,  the  Company was  organized  under the laws of the
    State of Michigan doing business as Audio Vestibular Testing Centers,  Inc.,
    and in the state of Illinois doing business as Integrated  Health  Services,
    Inc.  The  Company's  activities  were  limited  to  certain  organizational
    activities. The Company presently conducts the majority of its operations in
    the states of Michigan and Illinois.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (a) CASH AND CASH EQUIVALENTS

        For purposes of reporting cash flows, cash and cash equivalents  include
        cash on-hand and short-term  investments with original  maturities of 90
        days or less.

    (b) NET REVENUES

        Revenues  from the sale of hearing aid  products are  recognized  at the
        time of delivery. Revenues from the provision of hearing care diagnostic
        services are recognized at the time that such services are performed.

    (c) INVENTORY

        Inventory is stated at the lower of cost,  determined  on the  first-in,
        first-out  method, or market value.  Inventory  consists of hearing aids
        and  batteries,  which have been  purchased  from  vendors for resale to
        customers.


                                                                     (Continued)

                         THE MIDWEST DIVISION OF HEARING
                         HEALTH SERVICES, INC. dba SONUS

                          Notes to Financial Statements




    (d) EQUIPMENT AND FIXTURES

        Equipment and fixtures are stated at cost less accumulated  depreciation
        and  amortization.   Additions  and  betterments  are  capitalized,  and
        maintenance  and repairs are charged to current  operations as incurred.
        The cost of assets  retired or  otherwise  disposed  of and the  related
        accumulated depreciation and amortization are removed from the accounts,
        and  the  gain or loss on such  dispositions  is  reflected  in  current
        operations.  Amortization  of leasehold  improvements is provided on the
        straight-line  method  over the term of the  lease or  estimated  useful
        lives of the assets,  whichever is less. Depreciation is provided on the
        straight-line method. Estimated useful lives of the assets are:

          Professional equipment                                         7 years
          Furniture and fixtures                                         5 years
          Office equipment                                               5 years
          Leasehold improvements                                     1 - 5 years

    (e) INCOME TAXES

        The Company  accounts  for income  taxes  under the asset and  liability
        method.  Under the asset and liability  method,  deferred tax assets and
        liabilities are recognized for the future tax consequences  attributable
        to  differences  between the  financial  statement  carrying  amounts of
        existing  assets  and  liabilities  and their  respective  tax bases and
        operating  loss and tax credit  carryforwards.  Deferred  tax assets and
        liabilities  are measured  using enacted tax rates  expected to apply to
        taxable  income in the years in which those  temporary  differences  are
        expected to be recovered  or settled.  The effect on deferred tax assets
        and  liabilities of a change in tax rates is recognized in income in the
        period that includes the enactment date.


    (f) CONCENTRATIONS OF CREDIT RISK

        Financial   instruments,   which  potentially  subject  the  Company  to
        concentration  of credit  risk,  consist  principally  of cash and trade
        receivables.  The  Company  places  its cash  with high  credit  quality
        financial  institutions.  At times such  amounts may be in excess of the
        FDIC  insurance  limits.  The Company's  trade  accounts  receivable are
        derived  from  numerous  private  payors,  insurance  carriers,   health
        maintenance  organizations  and government  agencies.  Concentration  of
        credit risk relating to trade accounts  receivable is limited due to the
        diversity and number of patients and payors.

    (g) FAIR VALUE OF FINANCIAL INSTRUMENTS

        The  carrying  value  of  financial  instruments  such as cash  and cash

    The  difference  between  the total  income tax  expense  and the income tax
    expense computed using the statutory federal income tax rate for years ended
    June 30, 1996 and 1995 is as follows:

        Computed tax expense at
          statutory rate                     34.0%          34.0%
        State tax expense, net of
          federal taxes                       4.0%           2.1%
        Nondeductible expenses                0.6%           4.2%

                                             =====          =====

    The deferred income tax asset of $39,179 at June 30, 1996 relates  primarily
    to certain reserves not currently deductible for tax purposes.  No valuation
    allowance  was  deemed  necessary  and there was no change in the  valuation
    allowance  from the prior  year.  It is more likely than not that the entire
    amount of the deferred tax asset will be realized due to the taxable  income
    from the carryback availability in prior years.

        Certain of the leases contain  renewal  options and  escalation  clauses
        which require  payments of additional rent to the extent of increases in
        related  operating  costs.  Rent  expense  for fiscal  1996 and 1995 was

corporate of which the Registrant is or was a shareholder or a creditor, and his
heirs and legal representatives, from and against:

              (a) all costs,  charges,  and  expenses,  including  any amount to

         been a director or officer of the Registrant.

         The effect of this provision of the Registrant's bylaws when considered
in  light  of  Part  9,  Section  119  of  the  Act  is  to  grant  a  right  of
indemnification  to  the  above  referenced  individuals  against  all  expenses
(including  attorney fees and settlement costs)  reasonably  incurred in each of
the following circumstances:

              (a) the  individual  (i) acted  honestly  and in good faith with a
         view to the best  interests of the Registrant and (ii) in the case of a
         criminal or  administrative  action or proceeding that is enforced by a
         monetary  penalty,  had reasonable  grounds to believe that his conduct
         was lawful;

              (b) the individual was  substantially  successful on the merits on
         his defense of the action or proceeding  and acted honestly and in good
         faith with a view to the best interests of the  Registrant,  and in the
         case of a criminal or administrative action, had reasonable grounds for
         believing his conduct was lawful; and

              (c) in the  case of an  action  on  behalf  of the  Registrant  to
         procure a judgment  in its  favor,  to which the  individual  is made a
         party by reason of being or having  been a  director  or officer of the
         Registrant, the individual acted honestly and in good faith with a view
         to the best  interests of the  Registrant,  and the court approves such
         indemnification.

         The Act also permits the Registrant to purchase and maintain  insurance
for the  protection  of (i) its  directors and officers and (ii) any director or
officer of  another  body  corporate  acting at the  request of the  Registrant,
against liabilities  incurred in such person's capacity as a director or officer
of the  Registrant or of such other body  corporate,  except when such liability
relates to such  person's  failure to act honestly and in good faith with a view
to the best interests of the Registrant or such other body corporate.

Item 26.  Recent Sales of Unregistered Securities

         Within the last three years the Registrant has sold securities  without
registration  under  the  Securities  Act  of  1933  (the  "1933  Act")  in  the
transactions and in reliance on the exemptions described below.

Special Warrants

         During 1996, the Registrant undertook two separate offerings of Special
Warrants.  The first warrant offering was a private  placement in Canada and the
U.S. of 1,700,000 special warrants (the "February Special Warrants") that closed
in February 1996. The aggregate offering price for the February Special Warrants
was Cdn $1,700,000. Each February Special Warrant entitled the holder to acquire
1.1 shares of the  Registrant's  Common  Stock and a share  purchase  warrant to
purchase 1.1 additional  shares of the Registrant's  Common Stock. The number of
February  Special  Warrants issued to U.S. holders totaled 400,000 and were sold
to one individual and three entities as set forth below.  The private  placement
to U.S.  investors  of  February  Special  Warrants  was made in reliance on the
exemption  from  registration  contained  in Section  4(2) of the 1933 Act.  The
issuance of shares and purchase warrants upon the exercise or deemed exercise of
the February Special Warrants occurred on February 28, 1997.

         The February  Special  Warrants were issued with the assistance of Wood
Gundy, Inc. ("Wood Gundy").  In consideration  for its services,  Wood Gundy was
granted 32,500 February Special Warrants at a deemed issue price of Cdn$1.00 per
February Special Warrant and also received $65,000 in cash.

         The purchasers of the February Special Warrants were as follows:

         The second warrant offering related to a private placement in Canada of
810,000 special warrants  consummated in September 1996 and a private  placement
in the U.S. of 4,149,000  special  warrants  consummated in December 1996.  Such
special warrants are collectively  referred to herein as the "September  Special
Warrants." The aggregate  offering price for the September  Special Warrants was
U.S.$1,012,500  for those  sold in Canada and  $5,186,250  for those sold in the
United  States.  Each of the  September  Special  Warrants  placed in the United
States entitles the holder to acquire one share of the Registrant's Common Stock
and  one  share  purchase  warrant  to  purchase  one  additional  share  of the
Registrant's  Common Stock for U.S.$2.00 per share  exercisable for one share of
the  Registrant's  Common  Stock and a share  purchase  warrant to  purchase  an
additional  share.  Each of the  September  Special  Warrants  placed  in Canada
entitles the holder to acquire 1.1 shares of the Registrant's Common Stock and a
share  purchase  warrant to purchase 1.1 additional  shares of the  Registrant's
Common  Stock  for  U.S.$2.00  per  share  exercisable  for  one  share  of  the
Registrant's Common Stock and a share purchase warrant to purchase an additional
share.  The September  Special Warrants issued to U.S. holders were sold through
two  placement  agents to the  individuals  and entities  set forth  below.  The
private  placement to U.S.  investors of September  Special Warrants was made in
reliance on Rule 506 of Regulation D under the 1933 Act.

         C.M. Oliver & Company Limited (the "Canadian Agent") acted as agent for
the Registrant in connection with the offering of the September Special Warrants
in Canada.  The  Canadian  Agent  received  34,000  September  Special  Warrants
exercisable for one share of the Registrant's  Common Stock and a share purchase
warrant to  purchase  an  additional  share for  U.S.$2.00  per share in partial
payment of its selling  commission  and was granted an option to acquire  81,000
share purchase warrants (the "Agent's  Option"),  each exercisable for one share
of Common  Stock at a price of US$1.25 per share.  The  warrants  are subject to
certain  rights of the  Registrant  to force  exercise  or  cancellation  of the
Agent's Option.

         Sunrise  Securities  Corporation  ("Sunrise")  and  Dallas  Research  &
Trading, Inc. ("Dallas Research"), served as placement agents in connection with
the placement of the September  Special  Warrants in the United States.  Sunrise
and Dallas Research each received a selling commission equal to 9 percent of the
gross proceeds in the form of September Special Warrants,  or a total of 373,410
September  Special  Warrants.  Dallas  Research also received  20,000  September
Special Warrants in payment of its corporate finance fee. Such September Special
Warrants  are  exercisable  for one share of Common  Stock and a share  purchase
warrant to purchase one additional share of Common Stock for $2.00 per share. In
addition,  Sunrise and Dallas Research received an option to acquire 214,900 and
200,000 share purchase warrants, respectively, with each warrant exercisable for
one  share of Common  Stock at a price of $1.25  per  share.  The  warrants  are
subject  to  certain   rights  of  the  Registrant  to  force  the  exercise  or
cancellation of the warrants.

Item 27.  Exhibits

         The  exhibits to this  registration  statement  required by Item 601 of

Item 28.  Undertakings

         The Registrant will:

              (1)  File,   during  any  period  in  which  it  offers  or  sells
         securities,  a post-effective  amendment to this registration statement
         to:

                           (i)  Include  any  prospectus   required  by  Section
              10(a)(3) of the 1933 Act;

                           (ii)  Reflect in the  prospectus  any facts or events
              which, individually or together, represent a fundamental change in
              the information in the registration statement. Notwithstanding the
              foregoing,  any  increase  or  decrease  in volume  of  securities
              offered (if the total dollar value of the securities offered would
              not exceed that which was  registered)  and any deviation from the
              low or high end of the  estimated  maximum  offering  range may be
              reflected  in the form of  prospectus  filed  with the  Commission
              pursuant  to Rule  424(b)  if, in the  aggregate,  the  changes in
              volume  and  price  represent  no more  than a 20%  change  in the
              maximum aggregate  offering price set forth in the "Calculation of
              Registration Fee" table in the effective  registration  statement;
              and

                           (iii)  Include  any  additional  or changed  material
              information on the plan of distribution.

              (2) For  determining  liability  under  the 1933 Act,  treat  each
         post-effective  amendment  as  a  new  registration  statement  of  the
         securities offered,  and the offering of the securities at that time to
         be the initial bona fide offering.

              (3) File a  post-effective  amendment to remove from  registration
         any of the securities that remain unsold at the end of the offering.

         Insofar as indemnification  for liabilities  arising under the 1933 Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against public policy as expressed in the 1933 Act and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy  as  expressed  in the  1933  Act  and  will  be  governed  by the  final
adjudication  of such issue.  The undertaking of the Registrant in the preceding
sentence does not apply to insurance  against  liability  arising under the 1933
Act.

                            ARTICLES OF INCORPORATION


1.       NAME OF CORPORATION:  575035 ALBERTA LTD.

2.       THE CLASSES AND ANY MAXIMUM NUMBER OF SHARES THAT THE
         CORPORATION IS AUTHORIZED TO ISSUE:

         The  Corporation  is authorized to issue an unlimited  number of Common
         Shares  without  nominal  or par  value  and  an  unlimited  number  of
         Redeemable  Preferred  Shares without nominal or par value.  The Common
         Shares and the Redeemable  Preferred Shares shall have attached thereto
         the following rights, privileges, restrictions and conditions:

         Voting Rights

         (a) At all meetings of the  shareholders of the Corporation the holders
         of the Common  Shares  shall be  entitled to one (1) vote for each such
         share so held.

         (b)  Subject to the  provisions  of the  Business  Corporations  Act of
         Alberta,  the holders of the Redeemable  Preferred  Shares shall not be
         entitled to notice of or to vote at meetings of the shareholders of the
         Corporation.

         Dividends and Other Distributions

         (c) The Redeemable Preferred Shares shall not confer upon their holders
         any rights to dividends. Subject to the provisions of contained herein,
         the holders of the Common  Shares  shall be  entitled  to receive  such
         dividends as the directors may, in their  discretion,  declare thereon.
         In no event  shall  dividends  be paid on the Common  shares  where the
         payment  of such  dividends  would  result  in the  Corporation  having
         insufficient  assets  to  enable it to  redeem  all of the  issued  and
         outstanding  Redeemable  Preferred  Shares  at a  price  of One  Dollar
         ($1.00) per share in  accordance  with the  provisions  of the Business
         Corporations Act of Alberta.  The price of One Dollar ($1.00) per share
         is hereinafter referred to as the "Redemption Amount".

         (d) In the event of the  liquidation,  dissolution or winding-up of the
         Corporation or other distribution of its assets among the shareholders:

         (i)      the  holders  of the  Redeemable  Preferred  Shares  shall  be
                  entitled  to receive in  priority to the holders of the Common
                  Shares  an  amount  of  assets  having  a value  equal  to the
                  Redemption  Amount  of each  such  share  so held.  Except  as
                  provided  for in  this  sub-clause  2(d)  the  holders  of the
                  Redeemable  Preferred Shares shall not be entitled to share in
                  any distribution of the property or assets of the Corporation.

         (ii)     the holders of the Common  Shares shall be entitled to receive
                  the  remaining  property  of the  Corporation,  if any,  after
                  payment or  distribution  of  property  to the  holders of the
                  Redeemable  Preferred Shares as provided for in this subclause
                  2(d).

         Restriction on Purchase by Corporation of Common Shares

         (e) In no event shall the  Corporation  make any payment to purchase or
         otherwise acquire any of the Common Shares if such payment would result
         in the Corporation  having  insufficient  assets to enable it to redeem
         all of the issued and outstanding  Redeemable  Preferred  Shares at the
         Redemption  Amount per share in accordance  with the  provisions of the
         Business Corporations Act of Alberta.

         Redemption of Redeemable Preferred Shares

         (f) The Redeemable  Preferred Shares shall be redeemable in whole or in
         part at the option of either the holder thereof or the directors of the
         Corporation at a price per share equal to the Redemption Amount. In the
         event  that a part only of the then  outstanding  Redeemable  Preferred
         Shares is at any time to be redeemed at the option of the  directors of
         the  Corporation,  the number of such shares so to be redeemed shall be
         selected by lot, in such manner as the  directors  in their  discretion
         shall decide,  or, if the  directors so determine,  may be redeemed pro
         rata,  disregarding   fractions,   and  the  directors  may  make  such
         adjustments  as may be necessary to avoid the  redemption of fractional
         shares.  Not less than  thirty  (30)  days'  notice in  writing  of any
         redemption  of the  Redeemable  Preferred  Shares at the  option of the
         directors  shall be given by  mailing  such  notice  to the  registered
         holders of the Redeemable  Preferred Shares to be redeemed,  specifying
         the date and place or places of such redemption.  If notice of any such
         redemption be given by the  Corporation in the manner  aforesaid and an
         amount sufficient to redeem the shares shall have been deposited in any
         chartered  bank in  Canada,  trust  company,  or  Province  of  Alberta
         Treasury  Branches  as  specified  in the  notice on or before the date
         fixed for redemption,  the holders thereof shall have no rights against
         the  Corporation  in respect  thereof  except,  upon the  surrender  of
         certificates for such Redeemable  Preferred  Shares, to receive payment
         therefor out of the monies  deposited.  After the Redemption  Amount of
         such shares has been deposited in any chartered  bank in Canada,  trust
         company or Province of Alberta Treasury Branches, as aforesaid,  notice
         shall be given to the holders of any Redeemable Preferred Shares called
         for redemption who have failed to present the certificates representing
         such shares within two (2) months of the date  specified for redemption
         that the money has been so deposited and may be obtained by the holders
         of the  said  Redeemable  Preferred  Shares  upon  presentation  of the
         certificates  representing  such shares  called for  redemption  at any
         chartered bank in Canada, trust company or Province of Alberta Treasury
         Branches,  as the case may be; where a holder of  Redeemable  Preferred
         Shares  desires  that all or a portion  of such  shares  held by him be
         redeemed, he shall give notice in writing to the Corporation specifying
         the number of Redeemable Preferred Shares that he wishes to



                                                     - 2 -

         be  redeemed.  Within  sixty (60) days of receipt of such  notice,  the
         Corporation   shall,   subject  to  the   provisions  of  the  Business
         Corporations Act of Alberta,  redeem the number of Redeemable Preferred
         Shares specified in such notice,  and upon surrender of the certificate
         or certificates  for such Redeemable  Preferred  Shares the Corporation
         shall pay to the holder  thereof  the  Redemption  Amount in respect of
         each such Redeemable Preferred Share so redeemed.

         Variance of Shareholders' Rights

         (g) The rights, privileges, restrictions and conditions attached to the
         Common Shares or the Redeemable  Preferred Shares may only be varied if
         the  variation  is consented to by all of the holders of all the Common
         shares and the Redeemable  Preferred Shares which are outstanding.  The
         Corporation shall not without the approval of all of the holders of the
         Common Shares and the Redeemable  Preferred  Shares create or issue any
         class of shares  ranking as to capital  or  dividends  prior to or on a
         parity with the Common Shares and the Redeemable Preferred Shares.

         Corporation shall be subject to the following restrictions:

                  sub-clause   3(b)  below,   any  transfer  of  shares  in  the
                  Corporation  shall  require  a  resolution  of  the  Board  of
                  directors of the Corporation approving such transfer.

         (b)      Any share of a deceased  shareholder may be transferred by his

                  shareholder and any shares of the Corporation  standing in the
                  name of the trustees of the Will of any  deceased  shareholder
                  may be transferred upon any change of trustees to the trustees
                  for the time being of such Will.

         to serve  until the next  annual  general  meeting  of the  Corporation
         provided  that the  total  number  of  directors  shall not at any time

                                    or  affixing it to a door or placing in some
                                    other place at that address where the notice
                                    or communication is likely to be found;

                           (3)      by personally  serving it upon the Director;
                                    or

                           (4)      by  any   electronic   device   capable   of
                                    transmitting a printed  message  directed to
                                    the  Director at a place where the  Director
                                    has access to a device  capable of receiving
                                    the message; or

                           otherwise.

         All  notices  or  other  communication  given  or  made in  writing  in
         accordance   with  the   foregoing   shall  be   deemed  to  have  been
         communicated:

         (i)      if given or made by mail, at the time it would be delivered in
                  the  ordinary  course  of mail  unless  there  are  reasonable
                  grounds for  believing  that the  Director did not receive the
                  notice or communication at that time, or at all;

         (ii)     if  delivered  or  personally  served,  on the day that it was
                  delivered or served; and

         (iii)    if by electronic device, one (1) hour following transmission.

         by any  Director in writing or by  telecopy,  telegram,  cable or telex
         addressed  to the  Corporation  or in any  other  manner,  and any such
         waiver may be validly given either before or after the meeting to which
         such  waiver  relates.  Attendance  of a  Director  at any  meeting  of
         Directors  or of any  committee  of  Directors is a waiver of notice of
         such meeting,  except when a Director attends a meeting for the express
         purpose of objecting to the  transaction of any business on the grounds
         that the meeting is not lawfully called.

(f)      OMISSION  OF NOTICE:  The  accidental  omission  to give  notice of any
         meeting  of  Directors,  or of  any  committee  of  Directors,  or  the

         resolution passed or any proceeding taken at such meeting.

(g)      PLACE OF MEETINGS OF DIRECTORS:  Subject to the  Articles,  meetings of
         the  Directors  may be held at any  place in  Alberta,  or at any place

         otherwise, to the meeting being held at that place.

(h)      CHAIRMAN OF MEETINGS OF DIRECTORS OR COMMITTEE OF DIRECTORS: Unless and
         until the  Directors  have  elected a Chairman of the Board,  the Chief
         Executive  Officer  shall  act  as  chairman  of  all  meetings  of the
         Directors  but if the  Chairman  of the  Board or the  Chief  Executive
         Officer,  as the case may be, is absent or refuses to act as  chairman,
         the



                                                     - 4 -

<PAGE>



         Directors in  attendance  shall by a vote of the majority of them elect
         some other  Director  present at the  meeting to act as chairman of the
         meeting.

(i)      SECRETARY  OF  MEETINGS  OF  DIRECTORS:  The  chairman  of a meeting of
         Directors  may appoint a Director to act as  secretary  of a meeting of
         Directors, and in the absence of such appointment,  the chairman of the
         meeting shall also act as secretary of the meeting.

         shall constitute a quorum at any meeting of Directors.

         submitted  to a meeting  of  Directors  shall be decided by a vote of a
         majority  of the  Directors  participating  in  the  meeting,  and  the
         declaration  of the  chairman  of the meeting on the result of the vote
         shall be final.  In case of an equality of votes,  the  chairman of the
         meeting shall not have a casting vote.

2.11 MEETINGS OF COMMITTEES OF DIRECTORS: The provisions of Section 2.10 of this
By-law shall apply  equally to meetings of  committees  of  Directors,  but when
applying those  provisions to a meeting of a committee of Directors,  the phrase
"meeting of Directors"  shall mean "meeting of a committee of Directors" and the
word "Director" shall mean "member of a committee of Directors".

2.12  WRITTEN  RESOLUTION  IN  LIEU  OF  MEETING:  Subject  to the  Articles,  a
resolution  in  writing  signed by all the  Directors  entitled  to vote on that
resolution at a meeting of Directors or committee of Directors is as valid as if
it had been passed at a meeting of  Directors  or a committee  of  Directors.  A
resolution in writing may be signed in any number of counterparts which together
shall be construed as a single  instrument.  A resolution  in writing shall take
effect on the date when it is expressed to be effective notwithstanding that the
effective  date is  before  or after  the date on  which  it was  signed  by the
Directors or any of them.  A resolution  in writing  transmitted  by  telegraph,
telex or other device capable of  transmitting a printed  message and purporting

elect  some  other  person  in  attendance  at the  meeting,  who  need not be a
Shareholder, to act as chairman of the meeting.

of the  meeting  notwithstanding  that a quorum is not  present  throughout  the
meeting.

3.07 VOTING  JOINTLY HELD SHARES:  If two (2) or more persons hold shares of the
Corporation  jointly,  one of those holders present at a Meeting of Shareholders
may, in the absence of the  others,  vote the shares,  but if two (2) or more of
those persons who are present,  in person or by proxy,  vote, they shall vote as
one on the shares jointly held by them.

3.08  VOTING:  Voting at a  Meeting  of  Shareholders  shall be by show of hands

registered in the name of a Shareholder or his legal  representative  for a debt
of that  Shareholder to the Corporation,  such lien may be enforced,  subject to
the Act and to any  other  provision  of the  Articles,  by the  sale of  shares
thereby affected or by any other action, suit, remedy or proceedings  authorized
or permitted by law or by equity and, pending such enforcement,  the Corporation
may refuse to register a transfer of the whole or any part of such shares.

                                     PART 5

of the right to exercise the voting rights  attaching to any securities  held by
the Corporation.  Such  instruments,  certificates or other evidence shall be in
favour of such person or persons as may be determined  by the person  signing or
arranging for them. In addition,  the Board may direct the manner in which,  and
the person or persons by whom, any  particular  voting rights or class of voting
rights may or shall be exercised.

                                     PART 6
                          SHARES AND SHARE CERTIFICATES

6.01 ALLOTMENT:  Subject to the Articles, the Board may from time to time allot,
or grant options to purchase,  and issue the whole or any part of the authorized
and unissued shares of the Corporation at such times and to such persons and for
such consideration as the Board shall determine, provided that no share shall be
issued  until the  consideration  for the share is fully paid as provided for in
the Act.

6.02  COMMISSIONS:  The Board may from time to time authorize the Corporation to
pay a reasonable  commission to any person in consideration of his purchasing or
agreeing to purchase shares of the Corporation  from the Corporation or from any
other person,  or procuring or agreeing to procure  purchasers for shares of the
Corporation.

6.03  NON-RECOGNITION  OF TRUSTS:  Subject  to the  provisions  of the Act,  the
Corporation  may treat the  person in whose  name a share is  registered  in the
securities  register  as the  absolute  owner of the share as if that person had
full  legal  capacity  and  authority  to  exercise  all  rights  of  ownership,
irrespective  of any indication to the contrary  through  knowledge or notice or
description in the Corporation's records or on the share certificate.

6.04 SHARE  CERTIFICATES:  Every holder of one or more shares of the Corporation
shall  be  entitled,   at  his  option,  to  a  share   certificate,   or  to  a
non-transferable   written  acknowledgment  of  his  right  to  obtain  a  share
certificate,  stating  the  name  of the  person  to  whom  the  certificate  or
acknowledgment  was issued, and the number and class or series of shares held by
him as



                                                     - 7 -

<PAGE>



shown on the securities  register.  Share certificates and acknowledgements of a
Shareholder's right to a share certificate, shall, subject to the Act, be in
such form as the Board shall from time to time  approve.  Any share  certificate
shall be signed by any number of signing officers as the Board may determine and
need not be under the corporate seal,  provided that, unless the Board otherwise
determines,  certificates  representing  shares in  respect  of which a transfer
agent  and/or   registrar  has  been   appointed   shall  not  be  valid  unless
countersigned  by or on behalf of such  transfer  agent  and/or  registrar.  The
signature of a sole signing officer or two signing officers, as the case may be,
may be printed or mechanically  reproduced in facsimile upon share  certificates
and every such  facsimile  signature  shall for all purposes be deemed to be the
signature of the officer whose signature it reproduces and shall be binding upon
the  Corporation.  A share  certificate  executed  as  aforesaid  shall be valid
notwithstanding  that  one or both of the  officers  whose  facsimile  signature
appears thereon no longer holds office at the date of issue of the certificate.

6.05  REPLACEMENT  OF  SHARE  CERTIFICATE:  The  Board or any  officer  or agent
designated by the Board may in its or his  discretion  direct the issue of a new
share  certificate in lieu of and upon  cancellation of a share certificate that
has been mutilated or in substitution  for a share  certificate  claimed to have
been lost,  destroyed or wrongfully  taken, on payment of such fee not exceeding
such  amount as may be  allowed by the Act,  and on such terms as to  indemnity,
reimbursement  of  expenses  and  evidence of loss and of title as the Board may
from time to time prescribe, whether generally or in any particular case.

6.06 JOINT SHAREHOLDERS:  If two or more persons are registered as joint holders
of any  share,  the  Corporation  shall  not be  bound to  issue  more  than one
certificate in respect thereof,  and delivery of such certificate to one of such
persons shall be sufficient delivery to all of them. Any one of such persons may
give effectual receipts for the certificate issued in respect thereof or for any
dividend, bonus, return of capital or other money payable or warrant issuable in
respect of such share.

6.07 FRACTIONAL  SHARE: The Corporation may issue a certificate for a fractional
share or may  issue in its  place,  as may be  determined  by the  Board,  scrip
certificates  in a form that entitles the holder to receive a certificate  for a
full share by  exchanging  scrip  certificates  aggregating  a full  share.  The
Directors may attach  conditions to any scrip  certificates,  including that the
scrip certificates become void if they are not exchanged for a share certificate
representing  a full share by a  specified  date,  and that any shares for which
those scrip certificates are exchangeable may,  notwithstanding  any pre-emptive
right,  be issued by the  Corporation  to any person and the  proceeds  of those
shares distributed rateably to the holders of the scrip certificates.

6.08  TRANSFER AND  TRANSMISSION  OF SHARES:  Shares of the  Corporation  may be
transferred  in  the  form  of  a  transfer  of  endorsement   endorsed  on  the
certificates issued for the shares of the Corporation or in any form of transfer
which may be approved by the Board.

6.09 REGISTRATION OF TRANSFER: Subject to the provisions of the Act, no transfer
of shares shall be registered in a securities  register except upon presentation
of the certificate



                                                     - 8 -

representing such shares with a transfer endorsed thereon or delivered therewith
duly  executed by the  registered  holder or by his attorney or  successor  duly
appointed,  together  with such  reasonable  assurance or evidence of signature,
identification  and  authority  to  transfer  as the Board may from time to time
prescribe,  upon payment of all applicable  taxes and any fees prescribed by the
Board.

6.10  RIGHTS  OF  REPRESENTATIVES:  The  Corporation  may  treat a  person  as a
registered  Shareholder  entitled to exercise all rights of the  Shareholder  he
represents  if  that  person  produces  to the  Board  such  evidence  as may be
reasonably  required  that he is the  executor,  administrator,  heir  or  legal
representative  of the  heirs of the  estate  of a  deceased  Shareholder,  or a
guardian, committee or trustee representing a registered Shareholder.

6.11 NO DUTY TO THIRD PERSON:  The  Corporation  is not required to enquire into
the existence of, or see to the performance or observance of, any duty owed to a
third person by a registered  holder of any of its shares,  or by anyone whom it
treats, subject to the Act, as the owner or registered holder of its shares.

6.12 TRANSFER AGENTS AND REGISTRARS: The Board may from time to time appoint one
or more trust  companies  registered  under the Trust Companies Act (Alberta) as
its agent or agents to maintain the central  securities  register or  registers,
and an agent or agents to maintain branch  securities  registers.  Such a person
may be designated as transfer agent or registrar  according to his functions and

HealthCare Capital Corp.

Suite 2390
Portland, Oregon
U.S.A.   97204


Dear Sirs:

         Re:      HealthCare Capital Corp. - Form SB-2 Registration

                  We have acted as Alberta counsel for HealthCare Capital Corp.,
a  body  corporate  organized  under  the  laws  of  Alberta  ("HealthCare")  in
connection with the preparation of the Registration Statement on Form SB-2 to be
filed by HealthCare  with the Securities and Exchange  Commission (the "SEC") on
or shortly after February 24, 1997 (the  "Registration  Statement"),  respecting
the proposed resale of 25,312,814  common shares without par value of HealthCare
(the Offered Shares") by the Selling Shareholders identified in the Registration
Statement.

         The Offered Shares are comprised of the following:

         (i)      9,917,598 shares which are presently issued and outstanding;

         (ii)     A total of 6,449,658  shares (the "Warrant  Shares") which are
                  issuable  upon the  exercise  or deemed  exercise  of  special
                  warrants  issued  and  sold by  HealthCare  in  September  and
                  December of 1996 (the "Warrants")'

         (iii)    A total of 6,449,658  shares (the "Purchase  Warrant  Shares")
                  which are issuable upon the exercise of purchase warrants (the
                  "Purchase  Warrants") which are to be issued upon the exercise
                  or deemed exercise of the Warrants;

         (iv)     A total of 495,900  shares  (the  "Option  Shares")  which are
                  issuable  upon the exercise of purchase  warrants (the "Option
                  Warrants")  issuable  upon the exercise of options  granted to
                  the placement  agents in connection  with sales of Warrants in
                  September and December 1996; and

         (v)      a total of  2,000,000  shares  (the "Note  Shares")  which are
                  issuable upon  exercise of the  conversion  rights  associated
                  with  convertible  promissory  notes (the  "Notes")  issued by
                  HealthCare in connection  with the  acquisition of the Midwest
                  Division of Hearing Health Services, Inc., in October 1996.

                  In our  capacity as Alberta  counsel for  HealthCare,  we have
made such  investigations  and have  reviewed  such other  documents  as we have
deemed  necessary or  appropriate  under the  circumstances,  and have made such
examinations of law as we have deemed  appropriate for the purpose of giving the
opinions expressed herein.

                  We also have been furnished  with and have examined  originals
or copies,  certified or otherwise  identified to our satisfaction,  of all such
records  of  HealthCare,  agreements  and  other  instruments,  certificates  of
officers and representatives of HealthCare, certificates of public officials and
other  documents  as we have  deemed  necessary  or  relevant as a basis for the
opinion hereinafter expressed.

                  In  making  such   examinations,   we  have  assumed  (i)  the
genuineness of all signatures;  (ii) the authenticity of all documents submitted
to us as originals;  (iii) the conformity to original documents of all documents
submitted to us as certified  copies or  photocopies;  (iv) the authority of all
persons signing documents  examined by us except as to persons signing documents
on behalf of  HealthCare;  and (v) the identity and capacity of all  individuals
acting or purporting to act as public officials.

                  Based on the foregoing, we are of the opinion that:

1.       The Warrant Shares have been duly authorized and when the Warrants have
         been duly exercised or deemed to be exercised,  the Warrant Shares will
         be validly issued, fully paid and non-assessable.

2.       The  Purchase  Warrant  Shares have been duly  authorized  and when the
         Purchase  Warrants have been duly  exercised  and the Purchase  Warrant
         Shares have been duly delivered  against payment  therefor  pursuant to
         the terms of the Purchase  Warrants the Purchase Warrant Shares will be
         validly issued, fully paid and non-assessable.

3.       The  Option  Shares  have  been  duly  authorized  and when the  Option
         Warrants have been duly  exercised and the Option Shares have been duly
         delivered  against payment therefor pursuant to the terms of the Option
         Warrants,  the Option  Shares  will be validly  issued,  fully paid and
         non-assessable.

4.       The Note Shares have been duly  authorized  and when the holders of the
         Notes have duly exercised  their rights of conversion  thereunder,  the
         Note Shares will be validly issued, fully paid and non-assessable.

5.       The Offered  Shares  which are not  Warrant  Shares,  Purchase  Warrant
         Shares,  Option Shares or Note Shares have been validly  issued and are
         fully paid and non-assessable.

6.       The statements in the prospectus included in the Registration Statement
         (the "Prospectus")  under the heading "Service and Enforcement of Legal
         Process" to the extent that such  matters  represent  matters of law or
         legal conclusions, are accurate and complete statements or summaries of
         the matters set forth therein.

                  We express  no  opinion as to matters of law in  jurisdictions
other than the  Province  of Alberta and the laws of Canada  applicable  in such
province.

                  We hereby  consent to the filing of this opinion as an exhibit
to the Registration  Statement.  We further consent to the use of our name under
the headings  "Legal  Matters" and "Service and Enforcement of Legal Process" in

                                                              (BRITISH COLUMBIA)

                          PURCHASE OF SPECIAL WARRANTS


TO:               HEALTHCARE CAPITAL CORP.


         1. The undersigned  hereby irrevocably agrees to purchase special share
purchase  warrants (the "Special  Warrants")  of HealthCare  Capital Corp.  (the
"Corporation")  for an  aggregate  consideration  of $ (the  "Purchase  Price"),
representing a purchase  price of $1.00  (Canadian)  per Special  Warrant.  Each
Special  Warrant  shall  entitle the holder to acquire  one (1) Common  Share (a
"Common Share") of the Corporation and one (1) Common Share Purchase  Warrant (a
"Warrant")  at no  additional  cost at any  time on or  after  the  issue of the
Special  Warrants,  to and until 4:30 p.m. (Calgary time) (the "Expiry Time") on
the  earlier  of (a) the date  which is ten days  after  the date  upon  which a
receipt  is issued by the  securities  commission  in each of the  Provinces  of
Alberta  and  British  Columbia  (the  "Filing  Provinces")  for the  Prospectus
qualifying  the Common Shares and Warrants to be  distributed on the exercise of
the Special Warrants; and (b) 365 days from the Closing Date.

                  The Warrants shall have a term of two (2) years.  Each Warrant
entitles  the holder to  subscribe  for one (1)  additional  Common Share of the
Corporation  at a  subscription  price of $1.25 per  Common  Share if  exercised
during the first year after the Closing Date, and thereafter at $1.50 per Common
Share until the expiry of the term.

                  Any Special  Warrants  not  exercised  on or before the Expiry
Time shall be deemed to have been exercised immediately prior to the Expiry Time
without any further action on the part of the holder thereof.

         2. The Special  Warrants  will be duly and  validly  created and issued
pursuant to the terms of a warrant  indenture (the "Special Warrant  Indenture")
to be entered into between the  Corporation  and The R-M Trust Company of Canada
(the "Trustee"),  as trustee at or prior to the closing of the Special Warrants.
The  subscription  proceeds  from  the  sale  of the  Special  Warrants  will be
deposited in the Corporation's  bank accounts and  unconditionally  available to
the Corporation  upon receipt.  The Special  Warrant  Indenture shall be in such
form and  contain  such terms as shall be approved  by the  Corporation  and its
counsel. The Special Warrant Indenture will provide that, in the event a receipt
for the  Prospectus  is not obtained from the  securities  commission or similar
regulatory  authority  in each of the Filing  Provinces  on or prior to the date
which is 120 days from the Closing  Date,  each  holder of the Special  Warrants
shall be  entitled  to  receive,  upon the  exercise  or deemed  exercise of the
Special Warrants, 1.1 times the number of Common Shares and Warrants to which he
would otherwise be entitled to receive, without additional payment.

         3. By executing this Purchase  Agreement,  the undersigned  represents,
warrants and covenants to the Corporation (and acknowledges that the Corporation
is relying thereon) that:

         legislation  or a period  of  twelve  months  from the date of  closing

This is the form required under section 135 of the Rules and, if applicable,  by
an order issued under section 59 of the Securities Act.

                                  FORM 20A(IP)
                                 SECURITIES ACT

                     ACKNOWLEDGEMENT OF INDIVIDUAL PURCHASER


1.       (the    "Purchaser")   has   agreed   to   purchase   from   HealthCare
         -----------------------------------   Capital  Corp.   (the   "Issuer")
         Special        Warrants        at       $1.00        per        Special
         ------------------------------------------    Warrant.   Each   Special
         Warrant is convertible upon exercise, without further payment, into one
         Common Share of the Issuer (a "Share")  and one Common  Share  Purchase
         Warrant (a "Warrant"). One Warrant is exercisable to purchase a further
         Common  Share of the Issuer for two years from the date of  issuance of
         the Special  Warrants (the  "Closing"),  at a price of $1.25 during the
         first year, and $1.50 during the second year. The Special Warrants will
         be deemed to be exercised on that day which falls on the earlier of one
         year from the Closing,  and the day which is ten business days from the
         day  a  receipt  for  a  final   prospectus   qualifying  the  proposed
         distribution of the Shares and Warrants to holders of Special  Warrants
         (the  "Prospectus")  is  issued  by each of the  British  Columbia  and
         Alberta Securities Commissions. If such receipts are not issued by that
         day which falls 120 days from the day of the Closing, then each Special
         Warrant outstanding after that day will, on exercise entitle the holder
         to acquire 1.10 times the number of Common Shares and Warrants to which
         he would  otherwise  have been  entitled to receive,  at no  additional
         cost.  The  Special  Warrants  are  hereinafter   referred  to  as  the
         "Securities" of the Issuer.

2.       I am  purchasing  the  Securities  as principal  and, on closing of the
         agreement of purchase and sale, I will be the  beneficial  owner of the
         Securities.

3.       1 [CIRCLE ONE] have/have not received an offering memorandum describing
         the Issuer and the Securities.

4.       I acknowledge that:

         (a)      no securities  commission or similar regulatory  authority has
                  reviewed or passed on the merits of the Securities; AND

         (b)      there  is  no  government  or  other  insurance  covering  the
                  Securities, AND

         (e)      I WILL NOT  receive a  prospectus  that the  British  Columbia
                  Securities Act (the "Act") would otherwise require be given to
                  me because  the Issuer has  advised me that it is relying on a
                  prospectus exemption, AND

         (f)      because I am not purchasing the Securities under a prospectus,
                  I will not have the civil  remedies  that would  otherwise  be

         (g)      the Issuer has advised me that it is using an  exemption  from
                  the requirement to sell through a dealer  registered under the
                  Act, except purchases  referred to in paragraph 5(g), and as a
                  result I do not have the benefit of any protection  that might
                  have been available to me by having a dealer act on my behalf.

         Common  Share of the Issuer for two years from the date of  issuance of
         the Special  Warrants (the  "Closing"),  at a price of $1.25 during the
         first year, and $1.50 during the second year. The Special Warrants will
         be deemed to be exercised on that day which falls on the earlier of one

         to acquire 1.10 times the number of Common Shares and Warrants to which
         he would  otherwise  have been  entitled to receive,  at no  additional

         "Securities" of the Issuer.

2.       The Purchaser is purchasing the Securities as principal,  or is a trust
         company, insurer or portfolio manager acting on behalf of fully managed

                  a prospectus exemption; AND

         hereof and shall rank  equally  in  accordance  with its terms with all
         other Special Warrants issued or to be issued hereunder.

(b)      The  applicant for the issue of a new Warrant  Certificate  pursuant to
         this  Section 2.7 shall bear the cost of the issue  thereof and in case
         of loss,  destruction or theft shall,  as a condition  precedent to the

         evidence  of  ownership  and of the loss,  destruction  or theft of the
         Warrant   Certificate  so  lost,   destroyed  or  stolen  as  shall  be
         satisfactory  to the  Corporation  and to the  Trustee  in  their  sole
         discretion,  and such  applicant  may also be  required  to  furnish an

3.1               METHOD OF EXERCISE OF SPECIAL WARRANTS

(a)      The holder of any Special  Warrant  may  exercise  the right  evidenced
         thereby  conferred  on such holder to acquire  Common  Shares and Share

                           surrendered);

               (ii)        the  person or  persons  in whose  name or names such

         applicable  transfer or similar taxes and the Corporation  shall not be

         Special  Warrants and  compliance  with such other terms and conditions
         hereof as may be required,  the Corporation has appointed the principal

         Warrants   may  be  exercised   and  the  Trustee  has  accepted   such
         appointment.  The  Corporation  shall give notice to the Trustee of any
         change of the Warrant Agency.

3.2               EFFECT OF EXERCISE OF SPECIAL WARRANTS

(a)      Upon  compliance  by the  holder of any  Warrant  Certificate  with the
         provisions  of Section  3.1,  and  subject to Section  3.3,  the Common
         Shares and Share  Purchase  Warrants  subscribed for shall be deemed to
         have been issued and the person or persons to whom such  Common  Shares
         and Share  Purchase  Warrants  are to be issued shall be deemed to have
         become the holder or holders of record of such Common  Shares and Share
         Purchase Warrants on the Exercise Date unless the transfer registers of
         the Corporation  shall be closed on such date, in which case the Common
         Shares and Share  Purchase  Warrants  subscribed for shall be deemed to
         have been issued and such  person or persons  deemed to have become the
         holder or holders of record of such  Common  Shares and Share  Purchase
         Warrants, on the date on which such transfer registers are reopened.

(b)      Within  five (5)  Business  Days after the  Exercise  Date of a Special
         Warrant as set forth above, the Corporation shall cause to be mailed to
         the person or  persons  in whose  name or names the  Common  Shares and
         Share  Purchase  Warrants  so  subscribed  for  have  been  issued,  as
         specified  in  the  subscription,  at the  address  specified  in  such
         subscription  or, if so  specified  in such  subscription,  cause to be
         delivered  to such  person or persons at the Warrant  Agency  where the
         Warrant   Certificate   was   surrendered,   a  share   certificate  or
         certificates  for the  appropriate  number of Common Shares and a Share
         Purchase  Warrant  certificate or  certificates  for the Share Purchase
         Warrants.

(c)      In  the  event  of  the  exercise  of  Special  Warrants  prior  to the
         Corporation  obtaining  a receipt for the  Prospectus  from each of the
         Securities Commissions,  the Corporation may, on the advice of Counsel,
         endorse  the  certificates  representing  the  Common  Shares and Share
         Purchase  Warrants  issued on such  exercise  to the  effect  that such
         shares are subject to trading restrictions under applicable  securities
         legislation,  and prior to the  issuance of any such  certificates  the
         Trustee shall consult with the  Corporation  to determine  whether such
         endorsing or legending is required.

3.3               PARTIAL EXERCISE OF SPECIAL WARRANTS; FRACTIONS

(a)      The  holder  of any  Special  Warrants  may  acquire a number of Common
         Shares  and Share  Purchase  Warrants  less than the  number  which the
         holder is  entitled  to acquire  pursuant  to the  surrendered  Warrant
         Certificate(s)  provided  that,  in no event  shall  fractional  Common
         Shares and Share  Purchase  Warrants  be issued  with regard to Special
         Warrants  exercised.  In the  event of any  acquisition  of a number of
         Common  Shares and Share  Purchase  Warrants less than the number which
         the holder is entitled to acquire,  the holder of the Special  Warrants
         upon  exercise  thereof  shall,  in  addition,  be entitled to receive,
         without charge therefor, a new Warrant Certificate(s) in respect of the
         balance of the Common  Shares and Share  Purchase  Warrants  which such
         holder was entitled to



                                                     - 10 -

         acquire pursuant to the surrendered  Warrant  Certificate(s)  and which
         were not then acquired.

(b)      Notwithstanding  anything  herein  contained  including any  adjustment
         provided for in Article 4, the Corporation shall not be required,  upon
         the  exercise of any Special  Warrants,  to issue  fractions  of Common
         Shares and Share Purchase Warrants or to distribute  certificates which
         evidence fractional Common Shares and Share Purchase Warrants.  In lieu
         of fractional Common Shares and Share Purchase Warrants, there shall be
         paid  to the  holder  upon  surrender  of  Warrant  Certificate(s)  for
         exercise of Special  Warrants  pursuant to Section 3.1, within ten (10)
         Business  Days after the  Exercise  Date,  an amount in lawful money of
         Canada  equal  to the then  current  market  value  of such  fractional
         interest  computed  on the  basis of the  closing  price of the  Common
         Shares on The Alberta  Stock  Exchange (or if the Common Shares are not
         then  listed  thereon on such other  exchange  on which such shares are
         listed  or, if not  listed  on any  exchange,  in the  over-the-counter
         market,  as designated by action of the  directors) for the Trading Day
         immediately prior to the Exercise Date or where there is no sale on the
         applicable  exchange or market on the Trading Day immediately  prior to
         the  Exercise  Date,  the average of the last bid and ask prices on the
         applicable exchange or market, provided there shall be no cheque issued
         for less than $5.00.

         the following  declaration  (or such other form of  declaration  as the
         Corporation may prescribe from time to time):

                  "The  undersigned  (A)  acknowledges  that  the  sale  of  the
                  securities to which this declaration  relates is being made in
                  reliance on Rule 904 of  Regulation S under the United  States

                  United  States  and  either  (a) at the time the buy order was
                  originated,  the buyer was outside the United  States,  or the
                  seller and any person acting on its behalf reasonably  believe
                  that the  buyer  was  outside  the  United  States  or (b) the

                  acting  on its  behalf  knows  that the  transaction  has been
                  prearranged with a buyer in the United States, and (2) neither
                  the  seller,  nor any  affiliate  of the seller nor any person

                  directed selling efforts in connection with the offer and sale
                  of such securities.  Terms used herein have the meanings given
                  them by Regulation S.";

(c)      Notwithstanding  anything  set  forth in  Section  3.4(a)  or (b),  the
         Corporation may waive the  requirement  for, and direct the Trustee not

                           AND SHARE PURCHASE WARRANTS

4.1               ADJUSTMENT  OF  NUMBER  OF COMMON  SHARES  AND SHARE  PURCHASE
                  WARRANTS

                  The acquisition  rights in effect at any date attaching to the
Special Warrants shall be subject to adjustment from time to time as follows:

(a)      if and  whenever at any time from the date hereof and prior to the Time
         of Expiry, the Corporation shall:

                (i)        subdivide,  redivide or change its outstanding Common
                           Shares into a greater number of shares; or

                (ii)       reduce, combine or consolidate its outstanding Common
                           Shares into a smaller number of shares;

         the number of Common  Shares  and Share  Purchase  Warrants  obtainable
         under each  Special  Warrant  shall be adjusted  immediately  after the
         effective  date of such  subdivision,  redivision,  change,  reduction,
         combination  or  consolidation,  by  multiplying  the  number of Common
         Shares  and  Share  Purchase  Warrants  theretofore  obtainable  on the
         exercise  thereof by a  fraction  of which the  numerator  shall be the
         total number of Common Shares  outstanding  immediately after such date
         and  the  denominator  shall  be the  total  number  of  Common  Shares
         outstanding  immediately  prior to such date. Such adjustment  shall be
         made  successively  whenever any event  referred to in this  subsection
         shall occur;

(b)      if and  whenever at any time from the date hereof and prior to the Time
         of  Expiry,  there is a  reclassification  of the  Common  Shares  or a
         capital  reorganization  of the Corporation  other than as described in
         subsection  4.1(a),  or a consolidation,  amalgamation or merger of the
         Corporation with or into any other body corporate,  trust,  partnership
         or other entity,  or a sale or conveyance of the property and assets of
         the Corporation as an entirety or  substantially  as an entirety to any
         other  body  corporate,   trust,   partnership  or  other  entity,  any
         Warrantholder  who has not exercised its right of acquisition  prior to
         the   effective   date   of  such   reclassification,   reorganization,
         consolidation,  amalgamation,  merger,  sale  or  conveyance  upon  the
         exercise  of such right  thereafter,  shall be  entitled to receive and
         shall accept, in lieu of the number of Common Shares and Share Purchase
         Warrants  then  sought to be  acquired  by it,  the number of shares or
         other  securities  or  property  of  the  Corporation  or of  the  body
         corporate,  trust,  partnership  or other  entity  resulting  from such
         merger,  amalgamation  or  consolidation,  or to  which  such  sale  or
         conveyance  may be made,  as the case may be,  that such  Warrantholder
         would have been entitled to receive on such  reclassification,  capital
         reorganization,    consolidation,   amalgamation,   merger,   sale   or
         conveyance,  if, on the record date or the effective  date thereof,  as
         the case may be, the  Warrantholder  had been the registered  holder of
         the number of Common Shares and Share  Purchase  Warrants  sought to be
         acquired by it. If determined appropriate by the Trustee to give effect
         to or to  evidence  the  provisions  of  this  subsection  4.1(b),  the
         Corporation,   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  reclassification,   reorganization,
         consolidation,  amalgamation, merger, sale or conveyance, 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 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 Corporation and the
         Trustee pursuant to the provisions of this subsection 4.1(b) shall be a
         supplemental  indenture  entered  into  pursuant to the  provisions  of
         Article 8 hereof.  Any indenture  entered into between the Corporation,
         any successor to the  Corporation 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 provide in this Section 4.1 and which shall apply to
         successive    reclassification,     reorganizations,     amalgamations,
         consolidations, mergers, sales or conveyances; and

(c)      the adjustments  provided for in this Article 4 in the number of Common
         Shares and Share Purchase  Warrants and classes of securities which are
         to be received on the exer- cise of Special  Warrants  are  cumulative.
         After any adjustment pursuant to this Section, the term "Common Shares"
         and "Share  Purchase  Warrants"  where used in this Indenture  shall be
         interpreted  to mean  securities  of any class or classes  which,  as a
         result of such  adjustment and all prior  adjustments  pursuant to this
         Section,  the Warrantholder is entitled to receive upon the exercise of
         its Special Warrant, and the number of Common Shares and Share Purchase
         Warrants  indicated by any exercise made pursuant to a Special  Warrant
         shall be  interpreted  to mean the  number of Common  Shares  and Share
         Purchase  Warrants or other property or securities a  Warrantholder  is
         entitled  to  receive,  as a result  of such  adjustment  and all prior
         adjustments  pursuant  to this  Section,  upon the full  exercise  of a
         Special Warrant.

4.2               ENTITLEMENT TO COMMON SHARES AND SHARE PURCHASE WARRANTS
                  ON EXERCISE OF SPECIAL 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 Special 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 Special Warrant.

4.3               NO ADJUSTMENT FOR STOCK OPTIONS

                  Anything in this Article 4 to the contrary notwithstanding, no
adjustment  shall be made in the  acquisition  rights  attached  to the  Special
Warrants if the issue of Common Shares and Share Purchase Warrants is being made
pursuant to this  Indenture or pursuant to any stock option,  stock  purchase or
employee  RRSP plan in force from time to time for  officers or employees of the
Corporation.

4.4               DETERMINATION BY CORPORATION'S AUDITORS

                  In the  event of any  question  arising  with  respect  to the
adjustments  provided for in this Article 4 such question shall be  conclusively
determined by the Corporation's  Auditors who shall have access to all necessary
records of the  Corporation,  and such  determination  shall be binding upon the
Corporation,  the Trustee,  all  Warrantholders and all other persons interested
therein.

4.5               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 Special  Warrants,  including the number of Common Shares and Share Purchase
Warrants  which are to be received upon the exercise  thereof,  the  Corporation
shall take any  corporate  action  which may,  in the  opinion  of  counsel,  be
necessary  in order  that the  Corporation  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 holders of such  Special  Warrants are
entitled  to  receive  on the  full  exercise  thereof  in  accordance  with the
provisions hereof.

4.6               CERTIFICATE OF ADJUSTMENT

                  The Corporation  shall from time to time immediately after the
occurrence of any event which requires an adjustment or readjustment as provided
in Article 4, deliver a certificate of the Corporation to the Trustee specifying
the  nature of the event  requiring  the same and the  amount of the  adjustment
necessitated  thereby  and  setting  forth in  reasonable  detail  the method of
calculation  and  the  facts  upon  which  such  calculation  is  based,   which
certificate  shall be supported by a certificate of the  Corporation's  auditors
verifying such calculation.

4.7               NOTICE OF SPECIAL MATTERS

                  The  Corporation  covenants  with the Trustee that, so long as
any Special 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  Special  Warrants)  to all or
substantially  all the holders of its  outstanding  Common  Shares.  Such notice
shall specify the  particulars of such event and the record date for such event,
provided  that the  Corporation  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 case not
less than fourteen (14) days prior to such applicable record date.

4.8               NO ACTION AFTER NOTICE

                  The  Corporation  covenants  with the Trustee that it will not
close its transfer books or take any other corporate  action which might deprive
the holder of a Special  Warrant of the  opportunity  to  exercise  its right of
acquisition  pursuant  thereto during the period of fourteen (14) days after the
giving of the certificate or notices set forth in Section 4.6 and 4.7.

4.9               PROTECTION OF TRUSTEE

                  Except as provided in Section 9.2, the Trustee:

(a)      shall  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 Section  4.1, or with  respect to the
         nature or extent of any such  adjustment  when made, or with respect to
         the method employed in making the same;

(b)      shall not be accountable  with respect to the validity or value (or the
         kind or amount) of any Common Shares or Share  Purchase  Warrants or 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
         Special Warrant;

(c)      shall not be responsible  for any failure of the  Corporation to issue,
         transfer  or  deliver  Common  Shares  or Share  Purchase  Warrants  or
         certificates  for the same upon the  surrender of any Special  Warrants
         for the purpose of the exercise of such rights or to comply with any of
         the covenants contained in this Article; and

(d)      shall not incur any liability or responsibility whatsoever or be in any
         way responsible  for the  consequences of any breach on the part of the
         Corporation  of any of the  representations,  warranties  or  covenants
         herein  contained  or of any  acts of the  agents  or  servants  of the
         Corporation.

such Special  Warrants are then  obtainable,  plus reasonable costs of purchase,

(a)      it will reserve and keep  available such number of Common Shares as are
         sufficient  from time to time for the purpose of enabling it to satisfy
         its obligations to issue Common Shares upon the exercise of the Special
         Warrants and potential  obligation for the  subsequent  exercise of the
         Share Purchase  Warrants,  in the event that the  Corporation  does not
         have an unlimited number of Common Shares authorized;

(b)      it will cause the Common  Shares and Share  Purchase  Warrants  and the

(d)      it will use its  reasonable  best  efforts to  maintain  its  corporate
         existence;

(e)      it will use its  reasonable  best  efforts  to ensure  that all  Common
         Shares of the  Corporation  outstanding  or issuable  from time to time

         Days of the receipt  for a  Prospectus  in all of the Filing  Provinces
         advising  of the  issuance  of a  receipt  for  the  Prospectus  by the
         Securities  Commissions and of the date upon which the Special Warrants

so doing shall be  repayable  as provided in Section  5.3. No such  performance,

                  All or any of the rights  conferred upon any  Warrantholder by

benefit of the Warrantholders.


6.2               IMMUNITY OF SHAREHOLDERS, ETC.

                  The Trustee and, by the acceptance of the Warrant Certificates

Warrantholders hereby waive and release any right, cause of action or remedy now
or hereafter existing in any jurisdiction  against any incorporator or any past,
present  or future  shareholder,  director,  officer,  employee  or agent of the
Corporation   or  any  successor   Corporation   on  any  covenant,   agreement,
representation  or  warranty  by  the  Corporation  herein  or  in  the  Warrant
Certificates contained.

         outstanding shall have power (in addition to the powers  exercisable by
         extraordinary resolution as provided in Section 7.10) by requisition in
         writing to instruct the Trustee to waive any default  hereunder and the

(b)      the Trustee shall have power to waive any default  hereunder  upon such
         terms and  conditions  as the Trustee on advice of its counsel may deem
         advisable, if, in the Trustee's opinion, the same shall have been cured
         or adequate provision made therefor;

provided  that no delay or omission of the Trustee or of the  Warrantholders  to
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

7.1               RIGHT TO CONVENE MEETINGS

                  The Trustee  may at any time and from time to time,  and shall
on  receipt  of a written  request of the  Corporation  or of a  Warrantholders'
Request and upon being indemnified and funded to its reasonable  satisfaction by
the Corporation or by the Warrantholders  signing such  Warrantholders'  Request
against  the cost which may be  incurred  in  connection  with the  calling  and
holding of such meeting,  convene a meeting of the Warrantholders.  In the event
of the  Trustee  failing  to so  convene a meeting  within  seven (7) days after
receipt of such  written  request  of the  Corporation  or such  Warrantholders'
Request  and   indemnity   given  as   aforesaid,   the   Corporation   or  such
Warrantholders, as the case may be, may convene such meeting. Every such meeting
shall be held in the City of Calgary or at such other  place as may be  approved
or determined by the Trustee.

7.2               NOTICE

                  At  least  ten (10)  days'  prior  notice  of any  meeting  of
Warrantholders  shall be given to the  Warrantholders in the manner provided for
in Section  10.2 and a copy of such notice  shall be sent by mail to the Trustee
(unless  the  meeting has been  called by the  Trustee)  and to the  Corporation
(unless the meeting has been called by the Corporation). Such notice shall state
the time when and the place where the meeting is to be held, shall 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 shall not be necessary  for any such
notice  to set out the  terms of any  resolution  to be  proposed  or any of the
provisions of this Article 7.

7.3               CHAIRMAN

                  An individual (who need not be a Warrantholder)  designated in
writing by the Trustee  shall be chairman of the meeting and if no individual is
so designated,  or if the individual so designated is not present within fifteen
(15) minutes from the time fixed for the



                                                     - 21 -

holding of the meeting,  the Warrantholders  present in person or by proxy shall
choose some individual present to be chairman.

7.4               QUORUM

                  Subject to the  provisions  of Section 7.11, at any meeting of
the Warrantholders a quorum shall consist of Warrantholders present in person or
by proxy and entitled to purchase at least 25% of the aggregate number of Common
Shares  which could be acquired  pursuant  to all the then  outstanding  Special
Warrants,  provided  that at least two  persons  entitled  to vote  thereat  are
personally  present.  If a quorum of the  Warrantholders  shall  not be  present
within  thirty (30)  minutes  from the time fixed for holding any  meeting,  the
meeting,  if summoned by the  Warrantholders  or on a  Warrantholders'  Request,
shall be dissolved;  but in any other case the meeting shall be adjourned to the
same day in the next week (unless such day is not a Business  Day, in which case
it shall be adjourned to the next  following  Business Day) at the same time and
place and no notice  of the  adjournment  need be  given.  Any  business  may be
brought before or dealt with at an adjourned meeting which might have been dealt
with at the original  meeting in accordance with the notice calling the same. No
business  shall be transacted  at any meeting  unless a quorum be present at the
commencement of business. At the adjourned meeting the Warrantholders present in
person or by proxy shall form a quorum and may  transact  the business for which
the  meeting  was  originally  convened,  notwithstanding  that  they may not be
entitled to acquire at least 25% of the aggregate  number of Common Shares which
may be acquired pursuant to all then outstanding Warrants.

7.5               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 any such
meeting,  and no notice of such adjournment need be given except such notice, if
any, as the meeting may prescribe.

7.6               SHOW OF HANDS

                  Every question  submitted to a meeting shall be decided in the
first  place by a majority  of the votes  given on a show of hands  except  that
votes on an extraordinary  resolution  shall be given in the manner  hereinafter
provided.  At any  such  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 shall be conclusive evidence of the fact.

7.7               POLL AND VOTING

                  On every extraordinary  resolution,  and on any other question
submitted  to a meeting  and after a vote by show of hands when  demanded by the
chairman  or by one or more of the  Warrantholders  acting in person or by proxy
and entitled to acquire in the aggregate at least 5% of the aggregate  number of
Common Shares which could be acquired  pursuant to all the Special Warrants then
outstanding, a poll shall be taken in such manner as the chairman shall



                                                     - 22 -

direct.  Questions  other than those required to be determined by  extraordinary
resolution shall be decided by a majority of the votes cast on the poll.

                  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,  shall have one vote.  On a poll,  each  Warrantholder
present in person or  represented  by a proxy duly  appointed by  instrument  in
writing  shall be  entitled  to one vote in respect of each whole  Common  Share
which he is  entitled  to acquire  pursuant  to the  Special  Warrant or Special
Warrants then held or  represented  by it. A proxy need not be a  Warrantholder.
The Chairman of any meeting shall be entitled,  both on a show of hands and on a
poll, to vote in respect of the Special Warrants, if any, held or represented by
him.

7.8               REGULATIONS

                  The  Trustee,  or the  Corporation  with the  approval  of the
Trustee,  may from time to time make and from time to time vary such regulations

         person and will remain on deposit until after the meeting, which voting
         certificate  shall  entitle the persons named therein to be present and
         vote at any such meeting and at any adjournment thereof or to appoint a
         proxy  or  proxies  to  represent  them  and  vote for them at any such
         meeting and at any adjournment  thereof in the same manner and with the
         same effect as though the persons so named in such voting  certificates
         were the actual bearers of the Warrant Certificates specified therein;

(c)      the deposit of voting  certificates and instruments  appointing proxies
         at  such  place  and  time  as  the  Trustee,  the  Corporation  or the

         notice convening the meeting direct;

         at some  approved  place or  places  other  than the place at which the

         appointing proxies to be mailed or sent by facsimile before the meeting
         to the  Corporation 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;

such  regulations  may provide,  the only persons who shall be recognized at any
meeting as a Warrantholder,  or be entitled to vote or be present at the meeting
in respect thereof  (subject to Section 7.9), shall be  Warrantholders  or their
counsel, or proxies of Warrantholders.

7.11              MEANING OF EXTRAORDINARY RESOLUTION

(a)      The expression  "extraordinary  resolution" when used in this Indenture
         means,  subject as  hereinafter  provided in this  Section  7.11 and in
         Section 7.14, a resolution proposed at a meeting of Warrantholders duly
         convened for that purpose and held in accordance with the provisions of
         this  Article  7 at which  there  are  present  in  person  or by proxy
         Warrantholders entitled to acquire at least 25% of the aggregate number
         of  Common  Shares  which  may be  acquired  pursuant  to all the  then
         outstanding  Special  Warrants and passed by the  affirmative  votes of
         Warrantholders  entitled  to  acquire  not  less  than  66  2/3% of the
         aggregate number of Common Shares which may be acquired pursuant to all
         the then outstanding  Special  Warrants  represented at the meeting and
         vote on the poll upon such resolution.

(b)      If,  at the  meeting  at which  an  extraordinary  resolution  is to be
         considered,  Warrantholders  entitled  to  acquire  at least 25% of the
         aggregate number of Common Shares which may be acquired pursuant to all
         the then  outstanding  Special Warrants are not present in person or by
         proxy  within  thirty (30)  minutes  after the time  appointed  for the
         meeting,  then  the  meeting,  if  convened  by  Warrantholders  or  on

         stand  adjourned to such day, being not less than fifteen nor more than
         sixty (60) days later,  and to such place and time as  appointed by the
         chairman.  Not less than ten (10) days' prior  notice shall be given of
         the time and place of such adjourned meeting in the manner provided for
         in Section 10.2. Such notice shall state that at the adjourned  meeting
         the  Warrantholders  present in person or by proxy  shall form a quorum
         but it shall 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

         outstanding  Special  Warrants are not present in person or by proxy at
         such adjourned meeting.

(c)      Votes on an  extraordinary  resolution  shall always be given on a poll
         and no  demand  for a poll  on an  extraordinary  resolution  shall  be
         necessary.

7.12              POWERS CUMULATIVE

                  Any one or more of the powers or any combination of the powers
in  this  Indenture   stated  to  be  exercisable  by  the   Warrantholders   by
extraordinary resolution or otherwise may be exercised from time to time and the
exercise  of any one or more of such  powers or any  combination  of powers from
time to time shall not be deemed to exhaust the right of the  Warrantholders  to
exercise such power or powers or combination  of powers then or thereafter  from
time to time.

7.13                       MINUTES

7.16              HOLDINGS BY CORPORATION DISREGARDED

                  In  determining   whether   Warrantholders   holding   Warrant
Certificates evidencing the entitlement to acquire the required number of Common
Shares are present at a meeting of Warrantholders for the purpose of determining
a quorum or have  concurred in any consent,  waiver,  extraordinary  resolution,
Warrantholders'  Request or other action under this Indenture,  Special Warrants
owned  legally or  beneficially  by the  Corporation  or any  Subsidiary  of the
Corporation  shall be disregarded  in accordance  with the provisions of Section
10.8.


                                    ARTICLE 8
                             SUPPLEMENTAL INDENTURE

8.1               PROVISION FOR SUPPLEMENTAL INDENTURES FOR CERTAIN PURPOSES

                  From time to time the Corporation  (when  authorized by action
of the directors) and the Trustee may,  subject to the  provisions  hereof,  and
they shall, when so directed in accordance with the provisions  hereof,  execute
and deliver by their proper  officers,  indentures or  instruments  supplemental
hereto,  which thereafter shall form part hereof,  for any one or more or all of
the following purposes:

         (a) setting forth any adjustments resulting from the application of the
         provisions of Article 4;

(b)      adding  to  the  provisions   hereof  such  additional   covenants  and
         enforcement  provisions as, in the opinion of Counsel, are necessary or
         advisable  in the  premises,  provided  that  the  same  are not in the
         opinion  of  the  Trustee   prejudicial   to  the   interests   of  the
         Warrantholders;

         (c) giving effect to any extraordinary resolution passed as provided in
         Article 7;

(d)      making such provisions not  inconsistent  with this Indenture as may be
         necessary  or desirable  with  respect to matters or questions  arising
         hereunder or for the purpose of obtaining a listing or quotation of the
         Special  Warrants on any stock exchange,  provided that such provisions
         are not,  in the  opinion  of the  Trustee  on advice  of its  counsel,
         prejudicial to the interests of the Warrantholders;

(e)      adding to or altering the provisions  hereof in respect of the transfer
         of Special  Warrants,  making  provision  for the  exchange  of Warrant
         Certificates,  and making any  modification  in the form of the Warrant
         Certificates which does not affect the substance thereof;

(f)      modifying any of the provisions of this Indenture,  including relieving
         the Corporation from any of the obligations, conditions or restrictions
         herein contained, provided that such modification or relief shall be or
         become operative or effective only if, in the opinion of the Trustee on
         advice of its counsel, such modification or relief in no way



                                                     - 27 -

         prejudices any of the rights of the  Warrantholders  or of the Trustee,
         and  provided  further  that the  Trustee  may in its  sole  discretion
         decline  to enter  into any such  supplemental  indenture  which in its
         opinion may not afford adequate protection to the Trustee when the same
         shall become operative; and

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

8.2               SUCCESSOR CORPORATIONS

                  In the  case of the  consolidation,  amalgamation,  merger  or
transfer  of the  undertaking  or assets of the  Corporation  as an  entirety or
substantially as an entirety to another Corporation  ("successor  Corporation"),
the  successor  Corporation  resulting  from such  consolidation,  amalgamation,
merger  or  transfer  (if  not  the  Corporation)  shall  expressly  assume,  by
supplemental  indenture  satisfactory  in form to the Trustee and  executed  and
delivered to the Trustee,  the due and punctual  performance  and  observance of
each and every  covenant  and  condition of this  Indenture to be performed  and
observed by the Corporation.


                                    ARTICLE 9
                             CONCERNING THE TRUSTEE

9.1               TRUST INDENTURE LEGISLATION

(a)      If and to the  extent  that any  provision  of this  Indenture  limits,
         qualifies  or  conflicts  with a mandatory  requirement  of  Applicable
         Legislation, such mandatory requirement shall prevail.

(b)      The  Corporation  and the Trustee agree that each will, at all times in
         relation  to this  Indenture  and any  action  to be  taken  hereunder,
         observe and comply with and be entitled to the  benefits of  Applicable
         Legislation.

9.2               RIGHTS AND DUTIES OF TRUSTEE

(a)      In the exercise of the rights and duties prescribed or conferred by the
         terms of this  Indenture,  the Trustee  shall  exercise  that degree of
         care,  diligence  and skill that a  reasonably  prudent  trustee  would
         exercise in comparable  circumstances.  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 willful
         misconduct or bad faith.

(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   hereunder   shall   be   conditional   upon  the
         Warrantholders furnishing, when required by notice by the



                                                     - 28 -

         Trustee,  sufficient  funds to commence or to continue such act, action
         or proceeding and an indemnity  reasonably  satisfactory to the Trustee
         to protect and to 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  shall require the Trustee to expend or to
         risk its own funds or  otherwise  to incur  financial  liability in the
         performance  of any  of its  duties  or in the  exercise  of any of its
         rights or powers unless indemnified as aforesaid.

(c)      The  Trustee  may,  before   commencing  or  at  any  time  during  the
         continuance  of  any  such  act,  action  or  proceeding,  require  the
         Warrantholders,  at whose  instance  it is acting to  deposit  with the
         Trustee the Special  Warrants held by them, for which Special  Warrants
         the Trustee shall issue receipts.

(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 Applicable  Legislation,  of this
         Section 9.2 and of Section 9.3

9.3               EVIDENCE, EXPERTS AND ADVISERS

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

         (b) In the  exercise  of its rights and duties  hereunder,  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  in statutory
         declarations,  opinions, reports, written requests, consents, or orders
         of the  Corporation,  certificates of the Corporation or other evidence
         furnished to the Trustee pursuant to a request of the Trustee, provided
         that such evidence  complies with  Applicable  Legislation and that the
         Trustee  complies  with  Applicable  Legislation  and that the  Trustee
         examines the same and determines  that such evidence  complies with the
         applicable requirements of this Indenture.

(c)      Whenever  it  is  provided  in  this  Indenture  or  under   Applicable
         Legislation  that  the  Corporation  shall  deposit  with  the  Trustee
         resolutions, certificates, reports, opinions, requests, orders or other
         documents,  it is intended  that the trust,  accuracy and good faith on
         the  effective  date thereof and the facts and  opinions  stated in all
         such  documents so  deposited  shall,  in each and every such case,  be
         conditions  precedent  to the  right  of the  Corporation  to have  the
         Trustee take the action to be based thereon.

(d)      Proof  of the  execution  of an  instrument  in  writing,  including  a
         Warrantholders'  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 acknowledged to it the exe-



                                                     - 29 -

         cution thereof, or by an affidavit of a witness to such execution or in
         any other manner which the Trustee may consider adequate.

(e)      The Trustee may employ or retain such Counsel, accountants,  appraisers
         or other  experts or  advisers  as it may  reasonably  require  for the
         purpose of  discharging  its duties  hereunder  and may pay  reasonable
         remuneration  for all  services so  performed  by any of them,  without
         taxation of costs of any Counsel,  and shall not be responsible for any
         misconduct  or  negligence  on the part of any such experts or advisers
         who have been appointed with due care by the Trustee.

9.4               DOCUMENTS, MONIES, ETC.  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 Canadian chartered bank or
deposited for safekeeping with any such bank. Unless herein otherwise  expressly
provided, any monies so held pending the application or withdrawal thereof under
any  provisions of this Indenture may be deposited in the name of the Trustee in
any  Canadian  chartered  bank at the rate of interest  (if any) then current on
similar deposits or, with the consent of the Corporation,  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; or
(ii) invested in securities  issued or guaranteed by the Government of Canada or
a province thereof or in obligations  maturing not more than sixty days from the
date of  investment,  of any Canadian  chartered  bank or loan or trust company.
Unless the  Corporation  shall be in default  hereunder,  all  interest or other
income received by the Trustee in respect of such deposits and investments shall
belong to the Corporation.

9.5               ACTIONS BY TRUSTEE TO PROTECT INTEREST

                  The Trustee shall 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 Warrantholders.

9.6               TRUSTEE NOT REQUIRED TO GIVE SECURITY

                  The Trustee shall 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.

9.7               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  shall not be liable for or by reason of any  statements of
         fact or  recitals  in this  Indenture  or in the  Warrant  Certificates
         (except  the  representation   contained  in  Section  9.9  or  in  the
         certificate of the Trustee on the Warrant  Certificates) or be required
         to



                                                     - 30 -

<PAGE>



         verify the same,  but all such  statements or recitals are and shall be
         deemed to be made by the Corporation;

(b)      nothing herein  contained shall 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
         hereto;

         (c) the  Trustee  shall not be bound to give  notice  to any  person or
         persons of the execution hereof;

(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 Corporation of any of the covenants  herein  contained or of any
         acts of any directors,  officers,  employees, agents or servants of the
         Corporation; and

         (e) without  limiting any  protection or indemnity of the Trustee under
         any other provision hereof, or otherwise at law, the Corporation 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,  including 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 willful  misconduct  of the Trustee.  This
         provision  shall survive the  resignation  or removal of the Trustee or
         the termination of this Warrant Indenture.

9.8               REPLACEMENT OF TRUSTEE; SUCCESSOR BY MERGER

         (a) The Trustee may resign its trust and be discharged from all further
         duties and  liabilities  hereunder,  subject to this  Section  9.8,  by
         giving to the  Corporation not less than ninety (90) days' prior notice
         in writing or such shorter prior notice as the  Corporation  may accept
         as sufficient.  The  Warrantholders  by extraordinary  resolution shall
         have power at any time to remove the existing  Trustee and to appoint a
         new Trustee.  In the event of the Trustee resigning or being removed as
         aforesaid or being dissolved, becoming bankrupt, going into liquidation
         or otherwise  becoming  incapable of acting hereunder,  the Corporation
         shall forthwith  appoint a new trustee unless a new trustee has already
         been appointed by the  Warrantholders;  failing such appointment by the
         Corporation,  the retiring Trustee or any  Warrantholder may apply to a
         justice of the Court of  Queen's  Bench of the  Province  of Alberta on
         such notice as such justice may direct,  for the  appointment  of a new
         trustee;  but any new trustee so appointed by the Corporation or by the
         Court shall be subject to removal as aforesaid  by the  Warrantholders.
         Any new trustee appointed under any provision of this Section 9.8 shall
         be a Corporation authorized to carry on the business of a trust company
         in  the  Province  of  Alberta  and,  if  required  by  the  Applicable
         Legislation for any other provinces,  in such other  provinces.  On any
         such appointment the new trustee shall be vested with the same



                                                     - 31 -

<PAGE>



         powers,   rights,  duties  and  responsibilities  as  if  it  had  been
         originally named herein as Trustee hereunder.

(b)      Upon the  appointment of a successor  trustee,  the  Corporation  shall
         promptly notify the  Warrantholders  thereof in the manner provided for
         in Section 10.2 hereof.

(c)      Any  corporation  into or with  which  the  Trustee  may be  merged  or
         consolidated or amalgamated,  or any corporation resulting therefrom or
         any  corporation  succeeding to the trust business of the Trustee shall
         be the  successor to the Trustee  hereunder  without any further act on
         its part or any of the parties hereto,  provided that such  corporation
         would  be  eligible  for  appointment  as  a  successor  trustee  under
         subsection 9.8(a).

(d)      Any Warrant  Certificates  certified but not delivered by a predecessor
         trustee may be  certified by the  successor  trustee in the name of the
         predecessor or successor trustee.

9.9               CONFLICT OF INTEREST

(a)      The Trustee represents to the Corporation that at the time of execution
         and delivery hereof no material conflict of interest exists between its
         role as a  trustee  hereunder  and its role in any other  capacity  and
         agrees that in the event of a material  conflict  of  interest  arising
         hereafter it will,  within ninety (90) days after  ascertaining that it
         has such material  conflict of interest,  either  eliminate the same or
         assign its trust  hereunder  to a  successor  trustee  approved  by the
         Corporation  and  meeting  the  requirements  set  forth in  subsection
         9.8(a).

         Notwithstanding the foregoing  provisions of this subsection 9.9(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 9.9(a), the Trustee, in its personal or any other
         capacity,  may buy, lend upon and deal in securities of the Corporation
         and generally may contract and enter into financial  transactions  with
         the  Corporation  or any  Subsidiary of the  Corporation  without being
         liable to account for any profit made thereby.

9.10              ACCEPTANCE OF TRUST

                  The  Trustee  hereby  accepts  the  trusts  in this  Indenture
declared  and  provided  for and agrees to  perform  the same upon the terms and
conditions herein set forth.

         and recorded communication.


10.2              NOTICE TO WARRANTHOLDERS

(a)      Any notice to the Warrantholders under the provisions of this Indenture
         shall be valid and effective if sent by facsimile or letter or circular
         through  the  ordinary  post  addressed  to such  holders at their post
         office addresses appearing on the register  hereinbefore  mentioned and
         shall be deemed to have been effectively  given on the date of delivery
         or, if mailed,  five (5) Business Days following  actual posting of the
         notice.

(b)      If, by reason of a strike,  lockout or other work  stoppage,  actual or
         threatened,  involving postal employees,  any notice to be given to the
         Warrantholders  hereunder  could  reasonably be considered  unlikely to
         reach its destination, such notice shall be valid and effective only if
         it is delivered  personally to such  Warrantholders  or if delivered to
         the  address  for such  Warrantholders  contained  in the  register  of
         Special Warrants maintained by the Trustee, by facsimile or other means

                  The  Corporation  and the  Trustee  may  deem  and  treat  the
registered  owner of any Special  Warrants as the absolute owner thereof for all
purposes,  and the  Corporation  and the  Trustee  shall not be  affected by any
notice or knowledge to the contrary  except where the Corporation or the Trustee
is required to take notice under any statute or by order of a court of competent
jurisdiction.  A Warrantholder  shall be entitled to the rights evidenced by its
Warrant  Certificate free from all equities or rights of set off or counterclaim
between  the  Corporation  and the  original or any  intermediate  holder of the
Special Warrants and all persons may act accordingly and the receipt of any such
Warrantholder  for the Common Shares and Share  Purchase  Warrants  which may be
acquired  pursuant  thereto shall be a good discharge to the Corporation and the
Trustee for the same and neither the  Corporation nor the Trustee shall be bound
to inquire into the title of any such holder except where the Corporation or the
Trustee  is  required  to take  notice  by  statute  or by  order  of a court of
competent jurisdiction.


10.4              EVIDENCE OF OWNERSHIP

         Warrants  specified  therein have been deposited by a named person with
         such  bank,  trust  company  or other  depository  and will  remain  so
         deposited  until  the  expiry  of the  period  specified  therein,  the
         Corporation and the Trustee may treat the person so named as the owner,
         and such  certificate  as sufficient  evidence of the ownership by such
         person of such Special Warrant during such period, for the



                                                     - 34 -

         document  to be made,  signed  or given by the  holder  of the  Special
         Warrant so deposited.

(b)      The  Corporation  and the Trustee may accept as sufficient  evidence of
         the  fact  and  date  of the  signing  of any  requisition,  direction,
         consent,  instrument or other  document by any person (i) the signature
         of  any  officer  of any  bank,  trust  company,  or  other  depository
         satisfactory  to the  Trustee as witness  of such  execution,  (ii) the
         certificate  of any notary public or other  officer  authorized to take
         acknowledgements  of deeds  to be  recorded  at the  place  where  such
         certificate  is made that the person  signing  acknowledged  to him the
         execution thereof, or (iii) a satisfactory  declaration of a witness of
         such execution.


10.5              COUNTERPARTS

                  This Indenture may be executed in several  counterparts,  each
of  which  when  so  executed  shall  be  deemed  to be  an  original  and  such
counterparts   together  shall  constitute  one  and  the  same  instrument  and
notwithstanding  their date of execution  they shall be deemed to be dated as of
the date hereof.

10.6              SATISFACTION AND DISCHARGE OF INDENTURE

                  Upon the earlier of:

         (a) the date by which  there shall have been  delivered  to the Trustee
         for  exercise  or  destruction  all  Warrant  Certificates  theretofore
         certified hereunder; or

(b)      the Time of Expiry;

this Indenture shall cease to be of further effect and the Trustee, on demand of
and at the cost and expense of the  Corporation and upon delivery to the Trustee
of a certificate of the Corporation stating that all conditions precedent to the
satisfaction  and discharge of this  Indenture  have been complied  with,  shall
execute proper  instruments  acknowledging  satisfaction of and discharging this
Indenture.  Notwithstanding  the  foregoing,  the  indemnities  provided  to the
Trustee by the  Corporation  hereunder shall remain in full force and effect and
survive the termination of this Indenture.

10.7              PROVISIONS OF INDENTURE AND SPECIAL WARRANTS
                  FOR THE SOLE BENEFIT OF PARTIES AND WARRANTHOLDERS

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

(a)      duly completing and executing the Exercise Form attached hereto; and

(b)      surrendering this Special Warrant  Certificate to The R-M Trust Company
         (the  "Trustee") at the principal  office of the Trustee in the City of

                  These Special  Warrants shall be deemed to be surrendered only
upon  personal   delivery  hereof  or,  if  sent  by  mail  or  other  means  of
transmission,  upon actual receipt thereof by the Trustee at the office referred

                  Upon  surrender  of these  Special  Warrants,  the  person  or
persons  in whose name or names the Common  Shares and Share  Purchase  Warrants
issuable upon exercise of the Special  Warrants are to be issued shall be deemed

the holder shall be entitled to receive a new Special  Warrant  Certificate  for
the  balance  of the  Common  Shares and Share  Purchase  Warrants  which may be

                  The  Special  Warrants  represented  by this  certificate  are
issued under and pursuant to a Special Warrant Indenture  (hereinafter  referred
to as the "Indenture")  made as of February 28, 1996 between the Corporation and
the Trustee. Reference is made to the Indenture and any instruments supplemental
thereto  for a full  description  of the rights of the  holders  of the  Special
Warrants and the terms and  conditions  upon which the Special  Warrants are, or
are to be,  issued and held,  with the same effect as if the  provisions  of the
Indenture and all  instruments  supplemental  thereto were herein set forth.  By
acceptance  hereof,  the holder  assents  to all  provisions  of the  Indenture.
Capitalized terms used in the Indenture have the same meaning herein as therein,
unless otherwise defined.

                  In the event of any alteration of the Common Shares, including
any subdivision, consolidation or reclassification, and in the event of any form
of  reorganization  of the Corporation,  including any  amalgamation,  merger or
arrangement, the holders of Special Warrants shall, upon exercise of the Special
Warrants following the occurrence of any of those events, be entitled to receive
the same  number and kind of  securities  that they would have been  entitled to
receive had they  exercised  their  Special  Warrants  immediately  prior to the
occurrence of those events.

                  The registered holder of this Special Warrant Certificate may,
at any time prior to the Expiry Date,  upon  surrender  hereof to the Trustee at
its  principal  office in the City of Calgary,  exchange  this  Special  Warrant
Certificate  for other  Special  Warrant  Certificates  entitling  the holder to
acquire,  in the aggregate,  the same number of Common Shares and Share Purchase
Warrants as may be acquired under this Special Warrant Certificate.

                  The holding of the Special Warrants  evidenced by this Special
Warrant  Certificate shall not constitute the holder hereof a shareholder of the
Corporation  or entitle the holder to any right or  interest in respect  thereof
except as  expressly  provided  in the  Indenture  and in this  Special  Warrant
Certificate.

                  The Indenture  provides  that all holders of Special  Warrants
shall be bound by any  resolution  passed at a meeting  of the  holders  held in
accordance  with the provisions of the Indenture and  resolutions  signed by the
holders of Special  Warrants  entitled  to acquire a  specified  majority of the
Common  Shares which may be acquired  pursuant to all then  outstanding  Special
Warrants.

                  The  Special  Warrants   evidenced  by  this  Special  Warrant
Certificate  may be  transferred  on the  register  kept at the  offices  of the
Trustee by the  registered  holder  hereof or its legal  representatives  or its
attorney  duly  appointed  by an  instrument  in writing  in form and  execution
satisfactory to the Trustee, only upon compliance with the conditions prescribed
in the Indenture and upon compliance  with such  reasonable  requirements as the
Trustee may prescribe.

                  This Special  Warrant  Certificate  shall not be valid for any
purpose  whatever  unless and until it has been certified by or on behalf of the
Trustee.

                  Time shall be of the essence hereof.

                  The  Special  Warrants  represented  by this  certificate  are
issued under and pursuant to a Special Warrant Indenture  (hereinafter  referred
to as the "Indenture")  made as of February 28, 1996 between the Corporation and
the Trustee. Reference is made to the Indenture and any instruments supplemental
thereto  for a full  description  of the rights of the  holders  of the  Special
Warrants and the terms and  conditions  upon which the Special  Warrants are, or
are to be,  issued and held,  with the same effect as if the  provisions  of the
Indenture and all  instruments  supplemental  thereto were herein set forth.  By
acceptance  hereof,  the holder  assents  to all  provisions  of the  Indenture.
Capitalized terms used in the Indenture have the same meaning herein as therein,
unless otherwise defined.

                  In the event of any alteration of the Common Shares, including
any subdivision, consolidation or reclassification, and in the event of any form
of  reorganization  of the Corporation,  including any  amalgamation,  merger or
arrangement, the holders of Special Warrants shall, upon exercise of the Special
Warrants following the occurrence of any of those events, be entitled to receive
the same  number and kind of  securities  that they would have been  entitled to
receive had they  exercised  their  Special  Warrants  immediately  prior to the
occurrence of those events.

                  The registered holder of this Special Warrant Certificate may,
at any time prior to the Expiry Date,  upon  surrender  hereof to the Trustee at
its  principal  office in the City of Calgary,  exchange  this  Special  Warrant
Certificate  for other  Special  Warrant  Certificates  entitling  the holder to
acquire,  in the aggregate,  the same number of Common Shares and Share Purchase
Warrants as may be acquired under this Special Warrant Certificate.

                  The holding of the Special Warrants  evidenced by this Special
Warrant  Certificate shall not constitute the holder hereof a shareholder of the
Corporation  or entitle the holder to any right or  interest in respect  thereof
except as  expressly  provided  in the  Indenture  and in this  Special  Warrant
Certificate.

                  The Indenture  provides  that all holders of Special  Warrants
shall be bound by any  resolution  passed at a meeting  of the  holders  held in
accordance  with the provisions of the Indenture and  resolutions  signed by the
holders of Special  Warrants  entitled  to acquire a  specified  majority of the
Common  Shares which may be acquired  pursuant to all then  outstanding  Special
Warrants.

                  The  Special  Warrants   evidenced  by  this  Special  Warrant
Certificate  may be  transferred  on the  register  kept at the  offices  of the
Trustee by the  registered  holder  hereof or its legal  representatives  or its
attorney  duly  appointed  by an  instrument  in writing  in form and  execution
satisfactory to the Trustee, only upon compliance with the conditions prescribed
in the Indenture and upon compliance  with such  reasonable  requirements as the
Trustee may prescribe.

                  This Special  Warrant  Certificate  shall not be valid for any
purpose  whatever  unless and until it has been certified by or on behalf of the
Trustee.

                  Time shall be of the essence hereof.

         certification  by the  Trustee  upon any Warrant  Certificate  shall be
         conclusive  evidence  as  against  the  Corporation  that  the  Warrant
         Certificate  so certified  has been duly issued  hereunder and that the
         holder is entitled to the benefits hereof.

(b)      The  certification  of  the  Trustee  on  Warrant  Certificates  issued
         hereunder shall not be construed as a representation or warranty by the
         Trustee  as  to  the   validity  of  this   Indenture  or  the  Warrant
         Certificates  (except the due  certification  thereof)  and the Trustee

         issue  thereof,  furnish to the  Corporation  and to the  Trustee  such
         evidence  of  ownership  and of the loss,  destruction  or theft of the

         If any of the Common Shares subscribed for are to be issued to a person
         or persons other than the Warrantholder, the Warrantholder shall pay to
         the Corporation or the Warrant Agency on behalf of the Corporation, all
         applicable  transfer or similar taxes and the Corporation  shall not be
         required  to issue or deliver  certificates  evidencing  Common  Shares

         or the Warrant Agency on behalf of the Corporation,  the amount of such
         tax or shall have  established to the  satisfaction  of the Corporation
         that such tax has been paid or that no tax is due.

(c)      In connection with the exchange of Warrant Certificates and exercise of
         Warrants and compliance with such other terms and conditions  hereof as
         may be required, the Corporation has appointed the principal offices of
         the Trustee in Calgary as the agency at which Warrant  Certificates may
         be  surrendered  for exchange or at which Warrants may be exercised and
         the Trustee has accepted such  appointment.  The Corporation shall give
         notice to the Trustee of any change of the Warrant Agency.

3.2               Effect of Exercise of Warrants

(a)      Upon  compliance  by the  holder of any  Warrant  Certificate  with the
         provisions  of Section  3.1,  and  subject to Section  3.3,  the Common
         Shares  subscribed  for shall be deemed  to have  been  issued  and the
         person or persons to whom such Common  Shares are to be issued shall be
         deemed to have  become the  holder or holders of record of such  Common
         Shares on the  Exercise  Date  unless  the  transfer  registers  of the
         Corporation  shall be closed on such  date,  in which  case the  Common
         Shares  subscribed  for shall be deemed  to have been  issued  and such
         person or persons deemed to have become the holder or holders of record
         of such Common Shares, on the date on which such transfer registers are
         reopened.

(b)      Within five (5) Business  Days after the Exercise  Date of a Warrant as
         set forth above, the Corporation shall cause to be mailed to the person
         or persons in whose name or names the Common Shares so  subscribed  for
         have been  issued,  as specified  in the  subscription,  at the address
         specified   in  such   subscription   or,  if  so   specified  in  such
         subscription,  cause to be  delivered  to such person or persons at the
         Warrant Agency where the Warrant  Certificate was surrendered,  a share
         certificate or certificates for the appropriate number of Common Shares
         subscribed for.

3.3               Partial Exercise of Warrants; Fractions

(a)      The holder of any Warrants  may acquire a number of Common  Shares less
         than the number which the holder is entitled to acquire pursuant to the
         surrendered Warrant



                                                     - 10 -

         Certificate(s)  provided  that,  in no event  shall  fractional  Common
         Shares be issued with regard to Warrants exercised. In the event of any
         acquisition of a number of Common Shares less than the number which the
         holder is entitled to acquire, the holder of the Warrants upon exercise
         thereof  shall,  in addition,  be entitled to receive,  without  charge
         therefor, a new Warrant Certificate(s) in respect of the balance of the
         Common Shares which such holder was entitled to acquire pursuant to the
         surrendered Warrant Certificate(s) and which were not then acquired.

(b)      Notwithstanding  anything  herein  contained  including any  adjustment
         provided for in Article 4, the Corporation shall not be required,  upon
         the exercise of any Warrants, to issue fractions of Common Shares or to
         distribute  certificates  which evidence  fractional  Common Shares. In
         lieu of  fractional  Common  Shares,  there shall be paid to the holder
         upon  surrender  of Warrant  Certificate(s)  for  exercise  of Warrants
         pursuant  to  Section  3.1,  within  ten (10)  Business  Days after the
         Exercise  Date,  an amount in lawful  money of Canada equal to the then
         current market value of such fractional  interest computed on the basis
         of the closing price of the Common Shares on The Alberta Stock Exchange
         (or if the  Common  Shares  are not then  listed  thereon on such other
         exchange  on which  such  shares  are  listed  or, if not listed on any
         exchange,  in the  over-the-counter  market, as designated by action of
         the  directors) for the Trading Day  immediately  prior to the Exercise
         Date or where there is no sale on the applicable  exchange or market on
         the Trading Day immediately  prior to the Exercise Date, the average of
         the last bid and ask  prices  on the  applicable  exchange  or  market,
         provided there shall be no cheque issued for less than $5.00.

3.4      United States Holders

(a)      Upon the exercise of Warrants by a holder resident in the United States
         who acquired its Warrants  pursuant to the exercise of Special Warrants
         acquired  pursuant  to Rule 904 of the  Regulations  under  the  United
         States Securities Act of 1933, the certificates representing the Common
         Shares  issuable upon exercise of the Warrants shall bear the following
         legend:

                  "THE  SECURITIES  REPRESENTED  HEREBY HAVE NOT BEEN REGISTERED
                  UNDER THE UNITED  STATES  SECURITIES  ACT OF 1993,  AS AMENDED
                  (THE "SECURITIES  ACT"), THE HOLDER HEREOF, BY PURCHASING SUCH
                  SECURITIES,  AGREES FOR THE  BENEFIT OF THE  CORPORATION  THAT
                  SUCH SECURITIES MAY BE OFFERED,  SOLD OR OTHERWISE TRANSFERRED
                  ONLY (A) TO THE CORPORATION,  (B) OUTSIDE THE UNITED STATES IN
                  ACCORDANCE  WITH RULE 904 OF REGULATION S UNDER THE SECURITIES
                  ACT, (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION UNDER THE
                  SECURITIES  ACT  PROVIDED  BY  RULE  144  THEREUNDER,  OR  (D)

                  LEGAL OPINION TO THE CORPORATION. DELIVERY OF THIS CERTIFICATE
                  WILL  NOT   CONSTITUTE   "GOOD   DELIVERY"  IN  SETTLEMENT  OF
                  TRANSACTIONS ON STOCK EXCHANGES IN CANADA.  A NEW CERTIFICATE,
                  BEARING NO LEGEND,  DELIVERY  OF WHICH WILL  CONSTITUTE  "GOOD
                  DELIVERY",  MAY BE OBTAINED  FROM THE R-M TRUST  COMPANY  UPON
                  DELIVERY OF THIS CERTIFICATE AND A DULY EXECUTED  DECLARATION,
                  IN A FORM  SATISFACTORY  TO THE  R-M  TRUST  COMPANY  AND  THE
                  CORPORATION,  TO THE  EFFECT  THAT THE SALE OF THE  SECURITIES
                  REPRESENTED  HEREBY IS BEING MADE IN COMPLIANCE  WITH RULE 904
                  OF REGULATION S UNDER THE SECURITIES ACT.";

(b)      Notwithstanding  the provisions of Section 3.4(a),  the legend required
         by Section 3.4(a) may be removed by the holder providing to the Trustee
         the following  declaration  (or such other form of  declaration  as the
         Corporation may prescribe from time to time):

                  "The  undersigned  (A)  acknowledges  that  the  sale  of  the
                  securities to which this declaration  relates is being made in
                  reliance on Rule 904 of  Regulation S under the United  States
                  Securities Act of 1933, as amended, and (B) certifies that (1)
                  the offer of such  securities  was not made to a person in the
                  United  States  and  either  (a) at the time the buy order was
                  originated,  the buyer was outside the United  States,  or the
                  seller and any person acting on its behalf reasonably  believe
                  that the  buyer  was  outside  the  United  States  or (b) the
                  transaction  was executed on or through the  facilities of The
                  Alberta  Stock  Exchange and neither the seller nor any person
                  acting  on its  behalf  knows  that the  transaction  has been
                  prearranged with a buyer in the United States, and (2) neither
                  the  seller,  nor any  affiliate  of the seller nor any person
                  acting  on their  behalf  has  engaged  or will  engage in any
                  directed selling efforts in connection with the offer and sale
                  of such securities.  Terms used herein have the meanings given
                  them by Regulation S.";

(c)      Notwithstanding  anything  set  forth in  Section  3.4(a)  or (b),  the
         Corporation may waive the  requirement  for, and direct the Trustee not
         to  affix,  the  legend  set forth in  Section  3.4(a)  where  evidence
         satisfactory  to the  Corporation  has been  provided  by the holder of
         Warrants  that such  holder,  while being a United  States  resident is
         nevertheless a "qualified institutional buyer" as defined in the United
         States Securities Act of 1993.

                  Immediately  after the Time of Expiry,  all  rights  under any
Warrants  in  respect  of which  the right of  acquisition  herein  and  therein
provided for shall not have been  exercised  shall cease and  terminate and such
Warrant shall be void and of no further force or effect.


3.6               Cancellation of Surrendered Warrants

                  All Warrant  Certificates  surrendered  to the Warrant  Agency
pursuant to Sections 2.7, 2.8,  2.10,  3.1, 3.3 and 5.1 shall be returned to the
Trustee  for  cancellation  and,  after the  expiry of any  period of  retention
prescribed by law, destroyed by the Trustee and, upon request by the Corporation
the  Trustee  shall  furnish  to  the  Corporation  a  destruction   certificate
identifying  the Warrant  Certificates  so destroyed  and the number of Warrants
evidenced thereby.

3.7               Accounting and Recording

(b)      The Trustee shall record the  particulars of Warrants  exercised  which
         shall include the names and addresses of the persons who become holders

                      ADJUSTMENT OF NUMBER OF COMMON SHARES


4.1               Adjustment of Number of Common Shares

                  The  acquisition  rights as they relate to Common  Shares,  in
effect at any date attaching to the Warrants,  and the Exercise Price in respect
thereof, shall be subject to adjustment from time to time as follows:

(a)      if and whenever at any time after the  Effective  Date and prior to the
         Time of Expiry, the Corporation shall:

                (i)        subdivide,  redivide  or  change  outstanding  Common
                           Shares into a greater number of shares;




                                                     - 13 -

                (ii)       reduce, combine or consolidate the outstanding Common
                           Shares into a smaller number of shares, or

                (iii)      issue  Common   Shares  to  the  holders  of  all  or
                           substantially all of the outstanding Common Shares by
                           way of a stock  dividend  (other  than  the  issue of
                           Common Shares to holders of Common Shares pursuant to
                           their exercise of options to receive dividends in the
                           form of Common  Shares in lieu of  Dividends  Paid in
                           the Ordinary Course on the Common Shares),

         the Exercise Price in effect on the effective date of such subdivision,
         redivision,  reduction,  combination or  consolidation or on the record
         date for such issue of Common Shares by way of a stock dividend, as the
         case may be,  shall in the case of the  events  referred  to in (i) and
         (iii) above be decreased  in  proportion  to the number of  outstanding
         Common Shares resulting from such subdivision,  redivision or dividend,
         or shall,  in the case of the  events  referred  to in (ii)  above,  be
         increased in  proportion  to the number of  outstanding  Common  Shares
         resulting  from such  reduction,  combination  or  consolidation.  Such
         adjustment shall be made successively whenever any event referred to in
         this subsection  4.1(a) shall occur; any such issue of Common Shares by
         way of a stock dividend shall be deemed to have been made on the record
         date for the stock dividend for the purpose of  calculating  the number
         of outstanding Common Shares under subsections 4.1(b) and 4.1(c).  Upon
         any adjustment of the Exercise Price pursuant to subsection 4.1(a), the
         number of Common  Shares  subject to the right of  purchase  under each
         Warrant shall be  contemporaneously  adjusted by multiplying the number
         of Common Shares which  theretofore  may have been purchased under such
         Warrant by a fraction of which the  numerator  shall be the  respective
         Exercise Price in effect  immediately  prior to such adjustment and the
         denominator shall be the respective  Exercise Price resulting from such
         adjustment;

(b)      if and whenever at any time after the  Effective  Date and prior to the
         Time of  Expiry,  the  Corporation  shall  fix a  record  date  for the
         issuance of rights or warrants to all or substantially  all the holders
         of its outstanding  Common Shares entitling them, for a period expiring
         not more than 45 days after  such  record  date,  to  subscribe  for or
         purchase Common Shares (or securities  convertible or exchangeable into
         Common Shares) at a price per share (or having a conversion or exchange
         price per  share)  less than 95% of the  Current  Market  Price on such
         record date,  the Exercise  Price shall be adjusted  immediately  after
         such  record  date so that it shall  equal  the  amount  determined  by
         multiplying  the  Exercise  Price in  effect on such  record  date by a
         fraction  of which the  numerator  shall be the total  number of Common
         Shares  outstanding  on such record date plus a number of Common Shares
         equal to the number  arrived at by dividing the aggregate  price of the
         total number of additional  Common Shares offered for  subscription  or
         purchase  (or  the  aggregate  conversion  or  exchange  price  of  the
         convertible  or  exchangeable  securities  so offered) by such  Current
         Market Price, and of which the denominator shall be the total number of
         Common Shares  outstanding on such record date plus the total number of
         additional  Common Shares offered for  subscription or purchase or into
         which the convertible or exchangeable securities so offered are

         convertible or exchangeable; any Common Shares owned by or held for the
         account of the Corporation or any Subsidiary  shall be deemed not to be
         outstanding  for the purpose of any such  computation;  such adjustment
         shall be made successively whenever such a record date is fixed; to the
         extent that any such rights or warrants are not exercised  prior to the
         expiration  thereof,  the  Exercise  Price shall be  readjusted  to the
         Exercise  Price  which  would then be in effect if such record date had
         not been fixed or to the Exercise  Price which would be in effect based
         upon  the  number  of  Common  Shares  (or  securities  convertible  or
         exchangeable  into Common Shares)  actually issued upon the exercise of
         such rights or warrants, as the case may be;

(c)      if and whenever at any time after the  Effective  Date and prior to the
         Time of Expiry,  the Corporation shall fix a record date for the making
         of a  distribution  to all or  substantially  all  the  holders  of its
         outstanding  Common  Shares of (i) shares of any class,  whether of the
         Corporation  or any other  corporation  (other than  Common  Shares and
         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), (ii) rights,  options or warrants (excluding those referred to
         in subsection  4.1(b) and rights,  options or warrants to subscribe for
         or purchase  Common  Shares (or other  securities  convertible  into or
         exchangeable  for Common Shares) for a period expiring not more than 45
         days  after  such  record  date at a  price  per  share  (or  having  a
         conversion  or  exercise  price  per  share)  not less  than 95% of the
         Current  Market  Price on such record  date),  (iii)  evidences  of its
         indebtedness or (iv) assets  (excluding  Dividends Paid in the Ordinary
         Course)  then,  in each case,  the  Exercise  Price  shall be  adjusted
         immediately  after such  record  date so that it shall  equal the price
         determined by  multiplying  the Exercise Price in effect on such record
         date by a fraction, of which the numerator shall be the total number of
         Common Shares outstanding on such record date multiplied by the Current
         Market  Price on such  record  date,  less the fair  market  value  (as
         determined by the directors,  which  determination shall be conclusive)
         of such shares, rights, options, warrants, evidences of indebtedness or
         assets so distributed,  and of which the denominator shall be the total
         number of Common Shares  outstanding on such record date  multiplied by
         such Current  Market Price;  and Common Shares owned by or held for the
         account of the Corporation or any Subsidiary  shall be deemed not to be
         outstanding  for the purpose of any such  computation;  such adjustment
         shall be made successively whenever such a record date is fixed; to the
         extent that such  distribution is not so made, the Exercise Price shall
         be  readjusted  to the Exercise  Price which would then be in effect if
         such  record  date had not been fixed or to the  Exercise  Price  which
         would then be in effect  based upon such  shares or rights,  options or
         warrants or evidences of indebtedness  or assets actually  distributed,
         as the case may be; in clause (iv) of this  subsection  4.1(c) the term
         "Dividends Paid in the Ordinary  Course" shall include the value of any
         securities  or other  property  or assets  distributed  in lieu of cash
         Dividends Paid in the Ordinary Course at the option of shareholders;

(d)      if and when at any time from the  Effective  Date and prior to the Time
         of  Expiry,  there is a  reclassification  of the  Common  Shares  or a
         capital reorganization of the Corporation or as described in subsection
         4.1(a) or a consolidation, amalgamation, arrangement or

         merger of the Corporation with or into any other body corporate, trust,
         partnership  or other  entity,  or a sale or conveyance of the property
         and assets of the  Corporation  as an entirety or  substantially  as an
         entirety  to any other  body  corporate,  trust,  partnership  or other
         entity,   any   Warrantholder  who  has  not  exercised  its  right  of
         acquisition  prior  to the  effective  date of  such  reclassification,
         reorganization,  consolidation, amalgamation, arrangement, merger, sale
         or  conveyance,  upon the exercise of such right  thereafter,  shall be
         entitled to receive and shall  accept,  in lieu of the number of Common
         Shares  then sought to be acquired by it, the number of shares or other
         securities  or property of the  Corporation  or of the body  corporate,
         trust,   partnership  or  other  entity  resulting  from  such  merger,
         amalgamation,  arrangement or  consolidation,  or to which such sale or
         conveyance  may be made,  as the case may be,  that such  Warrantholder
         would have been entitled to receive on such  reclassification,  capital
         reorganization,  consolidation, amalgamation, arrangement, merger, sale
         or conveyance, if, on the record date or the effective date thereof, as
         the case may be, the  Warrantholder  had been the registered  holder of
         the number of Common  Shares sought to be acquired by it. If determined
         appropriate  by the  Trustee  to  give  effect  to or to  evidence  the
         provisions of this subsection 4.1(d),  the Corporation,  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
         reclassification,    reorganization,    consolidation,    amalgamation,
         arrangement,  merger, sale or conveyance, 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  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 Corporation and the Trustee pursuant
         to the  provisions of this  subsection  4.1(d) shall be a  supplemental
         indenture  entered into  pursuant to the  provisions  of Article 8. Any
         indenture  entered into between the  Corporation,  any successor to the
         Corporation 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  Section  4.1 and  which  shall  apply to  successive
         reclassification,    reorganizations,    amalgamation,    arrangements,
         consolidations, mergers, sales or conveyances;

(e)      in any case in which this Section 4.1 shall  require that an adjustment
         shall  become  effective  immediately  after a record date for an event
         referred to herein,  the Corporation may defer, until the occurrence of
         such event,  issuing to the holder of any Warrant  exercised after such
         record  date and before  the  occurrence  of such event the  additional
         Common Shares  issuable upon such exercise by reason of the  adjustment
         required by such event;  provided,  however, that the Corporation shall
         deliver  to such  holder  an  appropriate  instrument  evidencing  such
         holder's  right to  receive  such  additional  Common  Shares  upon the
         occurrence  of the event  requiring  such  adjustment  and the right to
         receive  any  distributions  made  on  such  additional  Common  Shares
         declared  in favour of holders of record of Common  Shares on and after
         the relevant  date of exercise or such later date as such holder would,
         but for the provisions of this subsection 4.1(e), have



                                                     - 16 -

         become the holder of record of such  additional  Common Shares pursuant
         to subsection 4.1(b);

(f)      in any case in which  subsections  4.1(b)  or  4.1(c)  require  that an
         adjustment be made to the Exercise Price,  no such adjustment  shall be
         made if, subject to the prior  approval of The Alberta Stock  Exchange,
         the holders of the outstanding  Warrants receive the rights or warrants
         referred  to in  subsection  4.1(b)  or the  shares,  rights,  options,
         warrants, evidences of indebtedness or assets referred to in subsection
         4.1(c),  as the case may be, in such kind and number as they would have
         received if they had been  holders of Common  Shares on the  applicable
         record date or effective  date,  as the case may be, by virtue of their
         outstanding  Warrant  having then been  exercised into Common Shares at
         the Exercise Price in effect on the applicable record date or effective
         date, as the case may be;

(g)      the adjustments  provided for in this Section 4.1 are  cumulative,  and
         shall,  in the case of adjustments to the Exercise Price be computed to
         the  nearest  whole cent and shall  apply to  successive  subdivisions,
         redivisions, reductions, combinations,  consolidations,  distributions,
         issues or other events resulting in any adjustment under the provisions
         of this Section 4.1 provided that,  notwithstanding any other provision
         of this Section,  no adjustment of the Exercise Price shall be required
         unless  such  adjustment  would  require an  increase or decrease of at
         least 1% in the Exercise Price then in effect; provided,  however, that
         any  adjustments  which by reason  of this  subsection  4.1(g)  are not
         required to be made shall be carried  forward and taken into account in
         any subsequent adjustment; and

(h)      after any  adjustment  pursuant to this  Section  4.1, the term "Common
         Shares"  where  used in this  Indenture  shall be  interpreted  to mean
         securities  of  any  class  or  classes  which,  as a  result  of  such
         adjustment and all prior adjustments  pursuant to this Section 4.1, the
         Warrantholder  is entitled to receive  upon the exercise of his Warrant
         and the number of Common Shares indicated by any exercise made pursuant
         to a Warrant shall be  interpreted  to mean the number of Common Shares
         or other property or securities a Warrantholder is entitled to receive,
         as a result of such  adjustment and all prior  adjustments  pursuant to
         this Section 4.1, upon the full exercise of a Warrant.

4.2               Entitlement to Common Shares on Exercise of  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 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.

4.3               No Adjustment for Stock Options or Warrants

                  Anything in this Article 4 to the contrary notwithstanding, no
adjustment  shall be made in the acquisition  rights attached to the Warrants if
the issue of Common Shares is being made pursuant to this  Indenture or pursuant
to any stock option,  stock purchase or employee RRSP plan in force from time to
time for officers or employees  of the  Corporation,  or pursuant to any warrant
outstanding immediately prior to the Effective Date.

4.4               Determination by Corporation's Auditors

                  In the  event of any  question  arising  with  respect  to the
adjustments  provided for in this Article 4 such question shall be  conclusively
determined by the Corporation's  Auditors who shall have access to all necessary
records of the  Corporation,  and such  determination  shall be binding upon the
Corporation,  the Trustee,  all  Warrantholders and all other persons interested
therein.

4.5               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  Warrants,  including  the number of Common  Shares which are to be received
upon the exercise thereof, the Corporation shall take any corporate action which
may, in the opinion of counsel,  be necessary in order that the  Corporation 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 holders of such
Warrants are entitled to receive on the full exercise thereof in accordance with
the provisions hereof.

4.6               Certificate of Adjustment

                  The Corporation  shall from time to time immediately after the
occurrence of any event which requires an adjustment or readjustment as provided
in Article 4, deliver a certificate of the Corporation to the Trustee specifying
the  nature of the event  requiring  the same and the  amount of the  adjustment
necessitated  thereby  and  setting  forth in  reasonable  detail  the method of
calculation  and  the  facts  upon  which  such  calculation  is  based,   which
certificate  shall be supported by a certificate of the  Corporation's  auditors
verifying such calculation.

4.7               Notice of  Matters

                  The  Corporation  covenants  with the Trustee that, so long as
any Warrant remains  outstanding,  it will give notice to the Trustee and to the
Warrantholders of its intention to fix the record date for any event referred to
in  subsection  4.1(a),  (b) or (c)  (other  than the  subdivision,  redivision,
reduction,  combination  or  consolidation  of its Common Shares) which may give
rise to an  adjustment  of the Exercise  Price.  Such notice  shall  specify the
particulars of such event and the record date for such event,  provided that the
Corporation  shall only be required to specify in the notice such particulars of
the event as shall have been fixed and



                                                     - 18 -

determined  on the date on which the notice is given.  The notice shall be given
in each case not less than  fourteen (14) days prior to such  applicable  record
date.

4.8               No Action after Notice

                  The  Corporation  covenants  with the Trustee that it will not
close its transfer books or take any other corporate  action which might deprive
the holder of a Warrant of the  opportunity to exercise its right of acquisition
pursuant thereto during the period of fourteen (14) days after the giving of the
certificate or notices set forth in Section 4.6 and 4.7.

4.9               Protection of Trustee

                  Except as provided in Section 9.2, the Trustee:

(a)      shall  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 Section  4.1, or with  respect to the
         nature or extent of any such  adjustment  when made, or with respect to
         the method employed in making the same;

(b)      shall not be accountable  with respect to the validity or value (or the
         kind  or  amount)  of any  Common  Shares  or 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 Warrant;

(c)      shall not be responsible  for any failure of the  Corporation to issue,
         transfer or deliver Common Shares or certificates for the same upon the
         surrender  of any  Warrants  for the  purpose of the  exercise  of such
         rights  or to  comply  with  any of the  covenants  contained  in  this
         Article; and

(d)      shall not incur any liability or responsibility whatsoever or be in any
         way responsible  for the  consequences of any breach on the part of the
         Corporation  of any of the  representations,  warranties  or  covenants
         herein  contained  or of any  acts of the  agents  or  servants  of the
         Corporation.

4.10              Other Adjustments

                  In case the  Corporation  after the date hereof shall take any
action  affecting the Common Shares  described in Article 4 which in the opinion
of the  directors  or the Trustee  would have a material  adverse  effect on the
rights of the  Warrantholders,  the Exercise Price and/or the number and/or kind
of Common Shares  purchaseable  upon  exercise,  there shall be an adjustment in
such manner, if any, and at such time, as the directors may determine subject to
the prior consent of The Alberta Stock Exchange. Failure of the taking of action
by the directors so as to provide for an adjustment  prior to the effective date
of any action by the Corporation affecting the Common Shares shall be conclusive
evidence  that the  directors  have  determined  that it is equitable to make no
adjustment in the circumstances.

                     RIGHTS OF THE CORPORATION AND COVENANTS


5.1               Optional Purchases by the Corporation

                  The  Corporation  may from time to time  purchase  by  private
contract or otherwise  any of the Warrants.  Any such purchase  shall be made at
the  lowest  price or prices at which,  in the  opinion of the  directors,  such
Warrants are then obtainable, plus reasonable costs of purchase, and may be made
in such manner, from such persons and on such other terms as the Corporation, in
its sole discretion,  may determine.  Any Warrant Certificates  representing the
Warrants  purchased pursuant to this Section 5.1 shall forthwith be delivered to
and  cancelled  by the  Trustee.  No  Warrants  shall be issued  in  replacement
thereof.

5.2               General Covenants

                  The Corporation covenants with the Trustee that so long as any
Warrants remain outstanding:

(a)      it will reserve and keep available a sufficient number of Common Shares
         for the  purpose of enabling  it to satisfy  its  obligations  to issue
         Common Shares upon the exercise of the Warrants,  in the event that the
         Corporation  does  not  have  an  unlimited  number  of  Common  Shares
         authorized;

(b)      it will cause the Common Shares and the  certificates  representing the
         Common  Shares from time to time  acquired  pursuant to the exercise of
         the  Warrants to be duly issued and  delivered in  accordance  with the
         Warrant Certificates and the terms hereof;

(c)      all Common  Shares which shall be issued upon  exercise of the right to
         acquire  provided for herein and in the Warrant  Certificates  shall be
         fully paid and non-assessable;

(d)      it will use its  reasonable  best  efforts to  maintain  its  corporate
         existence;

(e)      it will use its  reasonable  best  efforts  to ensure  that all  Common
         Shares of the  Corporation  outstanding  or issuable  from time to time
         continue  to be or are listed and  posted  for  trading on The  Alberta
         Stock Exchange;

(f)      it will make all requisite filings under applicable Canadian securities
         legislation  including those necessary to remain a reporting issuer not
         in default in Alberta and those necessary to report the exercise of the
         right to acquire Common Shares pursuant to Warrants; and

(g)      generally, it will well and truly perform and carry out all of the acts
         or things to be done by it as provided in this Indenture.

5.3               Trustee's Remuneration and Expenses

                  The Corporation covenants that it will pay to the Trustee from
time to time reasonable  remuneration for its services hereunder and will pay or
reimburse   the  Trustee   upon  its  request  for  all   reasonable   expenses,
disbursements and advances incurred or made by the Trustee in the administration
or execution of the trusts hereby created (including the reasonable compensation
and the  disbursements  of its counsel and all other advisers and assistants not
regularly in its employ) both before any default  hereunder and thereafter until
all duties of the Trustee hereunder shall be finally and fully performed, except
any such expense, disbursement or advance as may arise out of or result from the
Trustee's negligence, willful misconduct or bad faith.

5.4               Securities Qualification Requirements

(a)      If,  in the  opinion  of  counsel,  any  instrument  (not  including  a
         prospectus) is required to be filed with, or any permission is required
         to be obtained from any  governmental  authority in Canada or any other
         step is required  under any federal or provincial  law of Canada before
         any Common Shares which a Warrantholder is entitled to acquire pursuant
         to the  exercise of any Warrant may properly and legally be issued upon
         due exercise thereof and thereafter  traded,  without further formality
         or  restriction,  the  Corporation  covenants  that it will  take  such
         required action.

(b)      The  Corporation or, if required by the  Corporation,  the Trustee will
         give notice of the issue of Common  Shares  pursuant to the exercise of
         Warrants,  in  such  detail  as may be  required,  to  each  securities
         commission  or similar  regulatory  authority in each  jurisdiction  in
         Canada  in which  there is  legislation  or  regulation  permitting  or
         requiring  the  giving of any such  notice in order  that such issue of
         Common Shares and the  subsequent  disposition  of the Common Shares so
         issued will not be subject to the prospectus qualification requirements
         of such legislation or regulation.

5.5               Performance of Covenants by Trustee

                  If the Corporation  shall fail to perform any of its covenants
contained in this Warrant  Indenture,  the Trustee may notify the Warrantholders
of such failure on the part of the  Corporation or may itself perform any of the
covenants capable of being performed by it but, subject to Section 9.2, shall be
under no obligation to perform said covenants or to notify the Warrantholders of
such performance by it. All sums expended or advanced by the Trustee in so doing
shall be repayable as provided in Section 5.3. No such performance,  expenditure
or advance by the Trustee shall relieve the Corporation of any default hereunder
or of its continuing obligations under the covenants herein contained.

6.1               Suits by Warrantholders

                  All or any of the rights  conferred upon any  Warrantholder by
any of the terms of the Warrant  Certificates  or of the Indenture,  or of both,
may be enforced by the  Warrantholder  by  appropriate  proceedings  but without
prejudice to the right which is hereby  conferred upon the Trustee to proceed in
its own name to enforce each and all of the provisions  herein contained for the
benefit of the Warrantholders.

6.2               Suits by Corporation

                  The  Corporation  shall have the right to enforce full payment
of  the  Exercise  Price  of all  Common  Shares  issued  by  the  Trustee  to a
Warrantholder  hereunder,  and shall be entitled to demand such payment from the
Warrantholder  or  alternatively  to  instruct  the  Trustee to cancel the share
certificates and amend the securities register accordingly.

6.3               Immunity of Shareholders, etc.

                  The Trustee and, by the acceptance of the Warrant Certificates

Warrantholders hereby waive and release any right, cause of action or remedy now
or hereafter existing in any jurisdiction  against any incorporator or any past,
present  or future  shareholder,  director,  officer,  employee  or agent of the
Corporation   or  any  successor   Corporation   on  any  covenant,   agreement,
representation  or  warranty  by  the  Corporation  herein  or  in  the  Warrant
Certificates contained.

6.4               Limitation of Liability

                  The obligations hereunder are not personally binding upon, nor

present or future  directors or shareholders of the Corporation or any successor
Corporation or any of the past, present or future officers,  employees or agents
of the  Corporation or any successor  Corporation,  but only the property of the
Corporation or any successor Corporation shall be bound in respect hereof.

6.5               Waiver of Default

                  Upon the happening of any default hereunder:

(a)      the holders of not less than 51% of the Warrants then outstanding shall
         have power (in  addition  to the powers  exercisable  by  extraordinary
         resolution  as provided in Section 7.10) by  requisition  in writing to
         instruct  the  Trustee to waive any default  hereunder  and the Trustee
         shall  thereupon  waive the default upon such terms and  conditions  as
         shall be prescribed in such requisition; or

(b)      the Trustee shall have power to waive any default  hereunder  upon such
         terms and  conditions  as the Trustee on advice of its counsel may deem
         advisable, if, in the Trustee's opinion, the same shall have been cured
         or adequate provision made therefor;

provided  that no delay or omission of the Trustee or of the  Warrantholders  to
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.

                           MEETINGS OF WARRANTHOLDERS

7.1               Right to Convene Meetings

                  The Trustee  may at any time and from time to time,  and shall
on  receipt  of a written  request of the  Corporation  or of a  Warrantholders'
Request and upon being indemnified and funded to its reasonable  satisfaction by
the Corporation or by the Warrantholders  signing such  Warrantholders'  Request
against  the cost which may be  incurred  in  connection  with the  calling  and
holding of such meeting,  convene a meeting of the Warrantholders.  In the event
of the  Trustee  failing  to so  convene a meeting  within  seven (7) days after
receipt of such  written  request  of the  Corporation  or such  Warrantholders'
Request  and   indemnity   given  as   aforesaid,   the   Corporation   or  such
Warrantholders, as the case may be, may convene such meeting. Every such meeting
shall be held in the City of Calgary or at such other  place as may be  approved
or determined by the Trustee.

7.2               Notice

                  At  least  ten (10)  days'  prior  notice  of any  meeting  of
Warrantholders  shall be given to the  Warrantholders in the manner provided for
in Section  10.2 and a copy of such notice  shall be sent by mail to the Trustee
(unless  the  meeting has been  called by the  Trustee)  and to the  Corporation
(unless the meeting has been called by the Corporation). Such notice shall state
the time when and the place where the meeting is to be held, shall 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 shall not be necessary  for any such
notice  to set out the  terms of any  resolution  to be  proposed  or any of the
provisions of this Article 7.

7.3               Chairman

                  An individual (who need not be a Warrantholder)  designated in
writing by the Trustee  shall be chairman of the meeting and if no individual is
so designated,  or if the individual so designated is not present within fifteen
(15) minutes from the time fixed for the



                                                     - 23 -

holding of the meeting,  the Warrantholders  present in person or by proxy shall
choose some individual present to be chairman.

7.4               Quorum

                  Subject to the  provisions  of Section 7.11, at any meeting of
the Warrantholders a quorum shall consist of Warrantholders present in person or
by proxy and entitled to purchase at least 25% of the aggregate number of Common
Shares which could be acquired  pursuant to all the then  outstanding  Warrants,
provided  that at least two  persons  entitled to vote  thereat  are  personally
present.  If a quorum of the  Warrantholders  shall not be present within thirty
(30)  minutes  from the time fixed for  holding any  meeting,  the  meeting,  if
summoned  by  the  Warrantholders  or on a  Warrantholders'  Request,  shall  be
dissolved;  but in any other case the meeting shall be adjourned to the same day
in the next week (unless such day is not a Business  Day, in which case it shall
be adjourned to the next following  Business Day) at the same time and place and
no notice of the adjournment  need be given.  Any business may be brought before
or dealt with at an  adjourned  meeting  which might have been dealt with at the
original  meeting in  accordance  with the notice  calling the same. No business
shall  be  transacted  at  any  meeting  unless  a  quorum  be  present  at  the
commencement of business. At the adjourned meeting the Warrantholders present in
person or by proxy shall form a quorum and may  transact  the business for which
the  meeting  was  originally  convened,  notwithstanding  that  they may not be
entitled to acquire at least 25% of the aggregate  number of Common Shares which
may be acquired pursuant to all then outstanding Warrants.

7.5               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 any such
meeting,  and no notice of such adjournment need be given except such notice, if
any, as the meeting may prescribe.

7.6               Show of Hands

                  Every question  submitted to a meeting shall be decided in the
first  place by a majority  of the votes  given on a show of hands  except  that
votes on an extraordinary  resolution  shall be given in the manner  hereinafter
provided.  At any  such  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 shall be conclusive evidence of the fact.

7.7               Poll and Voting

                  On every extraordinary  resolution,  and on any other question
submitted  to a meeting  and after a vote by show of hands when  demanded by the
chairman  or by one or more of the  Warrantholders  acting in person or by proxy
and entitled to acquire in the aggregate at least 5% of the aggregate  number of
Common  Shares  which  could  be  acquired  pursuant  to all the  Warrants  then
outstanding, a poll shall be taken in such manner as the chairman shall direct.



                                                     - 24 -

<PAGE>



Questions other than those required to be determined by extraordinary resolution
shall be decided by a majority of the votes cast on the poll.

                  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,  shall have one vote.  On a poll,  each  Warrantholder
present in person or  represented  by a proxy duly  appointed by  instrument  in
writing  shall be  entitled  to one vote in respect of each whole  Common  Share
which he is entitled to acquire pursuant to the Warrant or Warrants then held or
represented  by it. A proxy need not be a  Warrantholder.  The  Chairman  of any
meeting  shall be  entitled,  both on a show of hands and on a poll,  to vote in
respect of the Warrants, if any, held or represented by him.

7.8               Regulations

                  The  Trustee,  or the  Corporation  with the  approval  of the
Trustee,  may from time to time make and from time to time vary such regulations
as it shall think fit for:

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

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

(d)      the deposit of voting  certificates and 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 such  instruments
         appointing proxies to be mailed or sent by facsimile before the meeting
         to the  Corporation 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)      the form of the instrument of proxy; and

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

                  Any regulations so made shall be binding and effective and the
votes given in accordance therewith shall be valid and shall be counted. Save as
such  regulations  may provide,  the only persons who shall be recognized at any
meeting as a Warrantholder,  or be entitled to vote or be present at the meeting
in respect thereof  (subject to Section 7.9), shall be  Warrantholders  or their
counsel, or proxies of Warrantholders.

7.9               Corporation and Trustee May be Represented

                  The   Corporation  and  the  Trustee,   by  their   respective
directors,  officers and employees,  and the counsel for the Corporation and for
the  Trustee  may attend any  meeting  of the  Warrantholders,  but shall not be
entitled to vote  thereat,  whether in respect of any  Warrants  held by them or
otherwise.

                  In addition  to all other  powers  conferred  upon them by any
other  provisions of this Indenture or by law, the  Warrantholders  at a meeting

from time to time by extraordinary resolution:

(a)      to agree to any  modification,  abrogation,  alteration,  compromise or

         Warrantholders;

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

(g)      to assent to any change in or omission from the provisions contained in
         the  Warrant  Certificates  and  this  Indenture  or any  ancillary  or
         supplemental instrument which may be agreed to by the Corporation,  and

         Corporation.

7.11              Meaning of Extraordinary Resolution

(a)      The expression  "extraordinary  resolution" when used in this Indenture
         means,  subject as  hereinafter  provided in this  Section  7.11 and in
         Section 7.14, a resolution proposed at a meeting of Warrantholders duly
         convened for that purpose and held in accordance with the provisions of
         this  Article  7 at which  there  are  present  in  person  or by proxy
         Warrantholders entitled to acquire at least 25% of the aggregate number
         of  Common  Shares  which  may be  acquired  pursuant  to all the  then
         outstanding   Warrants   and  passed  by  the   affirmative   votes  of
         Warrantholders  entitled  to  acquire  not  less  than  66  2/3% of the
         aggregate number of Common Shares which may be acquired pursuant to all
         the then  outstanding  Warrants  represented at the meeting and vote on
         the poll upon such resolution.

(b)      If,  at the  meeting  at which  an  extraordinary  resolution  is to be
         considered,  Warrantholders  entitled  to  acquire  at least 25% of the
         aggregate number of Common Shares which may be acquired pursuant to all
         the then  outstanding  Warrants  are not  present in person or by proxy
         within  thirty (30) minutes  after the time  appointed for the meeting,
         then the meeting,  if convened by Warrantholders or on  Warrantholders'
         Request, shall be dissolved;  but in any other shall stand adjourned to
         such day,  being not less than  fifteen  nor more than  sixty (60) days
         later,  and to such place and time as  appointed by the  chairman.  Not
         less than ten (10) days'  prior  notice  shall be given of the time and
         place of such adjourned  meeting in the manner  provided for in Section
         10.2.  Such  notice  shall  state  that at the  adjourned  meeting  the
         Warrantholders present in person or by proxy shall form a quorum but it
         shall 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 shall form a
         quorum  and may  transact  the  business  for  which  the  meeting  was
         originally convened and a resolution proposed at such adjourned meeting
         and passed by the  requisite  vote as  provided in  subsection  7.11(a)
         shall  be an  extraordinary  resolution  within  the  meaning  of  this
         Indenture  notwithstanding  that Warrantholders  entitled to acquire at
         least  25% of the  aggregate  number  of  Common  Shares  which  may be
         acquired pursuant to all the then outstanding  Warrants are not present
         in person or by proxy at such adjourned meeting.

(c)      Votes on an  extraordinary  resolution  shall always be given on a poll
         and no  demand  for a poll  on an  extraordinary  resolution  shall  be
         necessary.

7.12              Powers Cumulative

                  Any one or more of the powers or any combination of the powers
in  this  Indenture   stated  to  be  exercisable  by  the   Warrantholders   by
extraordinary resolution or otherwise may be exercised from time to time and the
exercise  of any one or more of such  powers or any  combination  of powers from
time to time shall not be deemed to exhaust the right of the  Warrantholders  to
exercise such power or powers or combination  of powers then or thereafter  from
time to time.

7.13                       Minutes

to time for that purpose by the Trustee at the expense of the  Corporation,  and
any such minutes as aforesaid, if signed by the chairman or the secretary of the
meeting at which such  resolutions were passed or proceedings had shall be prima

every such meeting in respect of the  proceedings  of which  minutes  shall have
been  made  shall be  deemed  to have  been  duly  convened  and  held,  and all
resolutions  passed  thereat or  proceedings  taken shall be deemed to have been
duly passed and taken.

7.14              Instruments in Writing

                  All  actions  which  may be taken and all  powers  that may be

may also be taken and exercised by  Warrantholders  entitled to acquire at least
66 2/3% of the aggregate number of Common Shares which may be acquired  pursuant
to all the then  outstanding  Warrants by an instrument in writing signed in one
or more  counterparts  by such  Warrantholders  in  person or by  attorney  duly
appointed in writing, and the expression "extraordinary resolution" when used in
this Indenture shall include an instrument so signed.

7.15              Binding Effect of Resolution

                  Every resolution and every extraordinary  resolution passed in
accordance with the provisions of this Article 7 at a meeting of  Warrantholders
shall be binding upon all the Warrantholders,  whether present at or absent from
such  meeting,  and every  instrument  in writing  signed by  Warrantholders  in
accordance  with  Section  7.14  shall be binding  upon all the  Warrantholders,
whether  signatories  thereto or not, and each and every  Warrantholder  and the
Trustee  (subject to the provisions  for indemnity  herein  contained)  shall be
bound to give effect  accordingly  to every such  resolution  and  instrument in
writing.

a quorum or have  concurred in any consent,  waiver,  extraordinary  resolution,
Warrantholders'  Request or other action under this  Indenture,  Warrants  owned
legally or  beneficially by the Corporation or any Subsidiary of the Corporation

         the interests of the Warrantholders;

(e)      adding to or altering the provisions  hereof in respect of the transfer

         and  provided  further  that the  Trustee  may in its  sole  discretion
         decline  to enter  into any such  supplemental  indenture  which in its
         opinion may not afford adequate protection to the Trustee when the same
         shall become operative; and

the  successor  Corporation  resulting  from such  consolidation,  amalgamation,
merger  or  transfer  (if  not  the  Corporation)  shall  expressly  assume,  by
supplemental  indenture  satisfactory  in form to the Trustee and  executed  and
delivered to the Trustee,  the due and punctual  performance  and  observance of
each and every  covenant  and  condition of this  Indenture to be performed  and
observed by the Corporation.

                             CONCERNING THE TRUSTEE

9.1               Trust Indenture Legislation

(a)      If and to the  extent  that any  provision  of this  Indenture  limits,
         qualifies  or  conflicts  with a mandatory  requirement  of  Applicable
         Legislation, such mandatory requirement shall prevail.

(b)      The  Corporation  and the Trustee agree that each will, at all times in
         relation  to this  Indenture  and any  action  to be  taken  hereunder,
         observe and comply with and be entitled to the  benefits of  Applicable
         Legislation.

9.2               Rights and Duties of Trustee

(a)      In the exercise of the rights and duties prescribed or conferred by the
         terms of this  Indenture,  the Trustee  shall  exercise  that degree of
         care,  diligence  and skill that a  reasonably  prudent  trustee  would
         exercise in comparable  circumstances.  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 willful
         misconduct or bad faith.

(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   hereunder   shall   be   conditional   upon  the
         Warrantholders furnishing, when required by notice by the



                                                     - 30 -

         Trustee,  sufficient  funds to commence or to continue such act, action
         or proceeding and an indemnity  reasonably  satisfactory to the Trustee
         to protect and to 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  shall require the Trustee to expend or to
         risk its own funds or  otherwise  to incur  financial  liability in the
         performance  of any  of its  duties  or in the  exercise  of any of its
         rights or powers unless indemnified as aforesaid.

(c)      The  Trustee  may,  before   commencing  or  at  any  time  during  the
         continuance  of  any  such  act,  action  or  proceeding,  require  the
         Warrantholders,  at whose  instance  it is acting to  deposit  with the
         Trustee the Warrants held by them, for which Warrants the Trustee shall
         issue receipts.

(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 Applicable  Legislation,  of this
         Section 9.2 and of Section 9.3

9.3               Evidence, Experts and Advisers

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

(b)      In the exercise of its rights and duties hereunder, 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  in  statutory  declarations,
         opinions,  reports,  written  requests,  consents,  or  orders  of  the
         Corporation,   certificates   of  the  Corporation  or  other  evidence
         furnished to the Trustee pursuant to a request of the Trustee, provided
         that such evidence  complies with  Applicable  Legislation and that the
         Trustee  complies  with  Applicable  Legislation  and that the  Trustee
         examines the same and determines  that such evidence  complies with the
         applicable requirements of this Indenture.

(c)      Whenever  it  is  provided  in  this  Indenture  or  under   Applicable
         Legislation  that  the  Corporation  shall  deposit  with  the  Trustee
         resolutions, certificates, reports, opinions, requests, orders or other
         documents,  it is intended  that the trust,  accuracy and good faith on
         the  effective  date thereof and the facts and  opinions  stated in all
         such  documents so  deposited  shall,  in each and every such case,  be
         conditions  precedent  to the  right  of the  Corporation  to have  the
         Trustee take the action to be based thereon.

(d)      Proof  of the  execution  of an  instrument  in  writing,  including  a
         Warrantholders'  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 acknowledged to it the exe-



                                                     - 31 -

         cution thereof, or by an affidavit of a witness to such execution or in
         any other manner which the Trustee may consider adequate.

(e)      The Trustee may employ or retain such Counsel, accountants,  appraisers
         or other  experts or  advisers  as it may  reasonably  require  for the
         purpose of  discharging  its duties  hereunder  and may pay  reasonable
         remuneration  for all  services so  performed  by any of them,  without
         taxation of costs of any Counsel,  and shall not be responsible for any
         misconduct  or  negligence  on the part of any such experts or advisers
         who have been appointed with due care by the Trustee.

9.4               Documents, Monies, etc.  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 Canadian chartered bank or
deposited for safekeeping with any such bank. Unless herein otherwise  expressly
provided, any monies so held pending the application or withdrawal thereof under
any  provisions of this Indenture may be deposited in the name of the Trustee in
any  Canadian  chartered  bank at the rate of interest  (if any) then current on
similar deposits or, with the consent of the Corporation,  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; or
(ii) invested in securities  issued or guaranteed by the Government of Canada or
a province thereof or in obligations  maturing not more than sixty days from the
date of  investment,  of any Canadian  chartered  bank or loan or trust company.
Unless the  Corporation  shall be in default  hereunder,  all  interest or other
income received by the Trustee in respect of such deposits and investments shall
belong to the Corporation.

9.5               Actions by Trustee to Protect Interest

                  The Trustee shall 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 Warrantholders.

9.6               Trustee Not Required to Give Security

                  The Trustee shall 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.

9.7               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  shall not be liable for or by reason of any  statements of
         fact or  recitals  in this  Indenture  or in the  Warrant  Certificates
         (except  the  representation   contained  in  Section  9.9  or  in  the
         certificate of the Trustee on the Warrant  Certificates) or be required
         to



                                                     - 32 -

<PAGE>



         verify the same,  but all such  statements or recitals are and shall be
         deemed to be made by the Corporation;

(b)      nothing herein  contained shall 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
         hereto;

(c)      the Trustee  shall not be bound to give notice to any person or persons
         of the execution hereof;

(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 Corporation of any of the covenants  herein  contained or of any
         acts of any directors,  officers,  employees, agents or servants of the
         Corporation; and

(e)      without  limiting any  protection or indemnity of the Trustee under any
         other provision  hereof,  or otherwise at law, the  Corporation  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,  including 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 willful  misconduct  of the Trustee.  This
         provision  shall survive the  resignation  or removal of the Trustee or
         the termination of this Warrant Indenture.

9.8               Replacement of Trustee; Successor by Merger

(a)      The  Trustee  may resign its trust and be  discharged  from all further
         duties and  liabilities  hereunder,  subject to this  Section  9.8,  by
         giving to the  Corporation not less than ninety (90) days' prior notice
         in writing or such shorter prior notice as the  Corporation  may accept
         as sufficient.  The  Warrantholders  by extraordinary  resolution shall
         have power at any time to remove the existing  Trustee and to appoint a
         new Trustee.  In the event of the Trustee resigning or being removed as
         aforesaid or being dissolved, becoming bankrupt, going into liquidation
         or otherwise  becoming  incapable of acting hereunder,  the Corporation
         shall forthwith  appoint a new trustee unless a new trustee has already
         been appointed by the  Warrantholders;  failing such appointment by the
         Corporation,  the retiring Trustee or any  Warrantholder may apply to a
         justice of the Court of  Queen's  Bench of the  Province  of Alberta on
         such notice as such justice may direct,  for the  appointment  of a new
         trustee;  but any new trustee so appointed by the Corporation or by the
         Court shall be subject to removal as aforesaid  by the  Warrantholders.
         Any new trustee appointed under any provision of this Section 9.8 shall
         be a Corporation authorized to carry on the business of a trust company
         in  the  Province  of  Alberta  and,  if  required  by  the  Applicable
         Legislation for any other provinces,  in such other  provinces.  On any
         such appointment the new trustee shall be vested with the same



                                                     - 33 -

<PAGE>



         powers,   rights,  duties  and  responsibilities  as  if  it  had  been
         originally named herein as Trustee hereunder.

(b)      Upon the  appointment of a successor  trustee,  the  Corporation  shall
         promptly notify the  Warrantholders  thereof in the manner provided for
         in Section 10.2 hereof.

(c)      Any  corporation  into or with  which  the  Trustee  may be  merged  or
         consolidated or amalgamated,  or any corporation resulting therefrom or
         any  corporation  succeeding to the trust business of the Trustee shall
         be the  successor to the Trustee  hereunder  without any further act on
         its part or any of the parties hereto,  provided that such  corporation
         would  be  eligible  for  appointment  as  a  successor  trustee  under
         subsection 9.8(a).

(d)      Any Warrant  Certificates  certified but not delivered by a predecessor
         trustee may be  certified by the  successor  trustee in the name of the
         predecessor or successor trustee.

9.9               Conflict of Interest

(a)      The Trustee represents to the Corporation that at the time of execution
         and delivery hereof no material conflict of interest exists between its
         role as a  trustee  hereunder  and its role in any other  capacity  and
         agrees that in the event of a material  conflict  of  interest  arising
         hereafter it will,  within ninety (90) days after  ascertaining that it
         has such material  conflict of interest,  either  eliminate the same or
         assign its trust  hereunder  to a  successor  trustee  approved  by the
         Corporation  and  meeting  the  requirements  set  forth in  subsection
         9.8(a).

         Notwithstanding the foregoing  provisions of this subsection 9.9(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 9.9(a), the Trustee, in its personal or any other
         capacity,  may buy, lend upon and deal in securities of the Corporation
         and generally may contract and enter into financial  transactions  with
         the  Corporation  or any  Subsidiary of the  Corporation  without being
         liable to account for any profit made thereby.

9.10              Acceptance of Trust

                  The  Trustee  hereby  accepts  the  trusts  in this  Indenture
declared  and  provided  for and agrees to  perform  the same upon the terms and
conditions herein set forth.

9.11              Trustee Not to be Appointed Receiver

                  The Trustee and any person related to the Trustee shall not be
appointed a receiver, a receiver and manager or liquidator of all or any part of
the assets or undertaking of the Corporation.

         the fifth (5th) Business Day following the date of the postmark on such
         notice.

(b)      The  Corporation  or the Trustee,  as the case may be, may from time to
         time notify the other in the manner provided in subsection 10.1(a) of a
         change of address  which,  from the  effective  date of such notice and
         until changed by like notice,  shall be the address of the  Corporation
         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 Corporation  hereunder could reasonably be considered
         unlikely  to reach  its  destination,  such  notice  shall be valid and
         effective  only if it is delivered to the named officer of the party to
         which it is  addressed  or,  if it is  delivered  to such  party at the

         date of delivery or, if mailed, five (5) Business Days following actual
         posting of the notice.

(b)      If, by reason of a strike,  lockout or other work  stoppage,  actual or
         threatened,  involving postal employees,  any notice to be given to the
         Warrantholders  hereunder  could  reasonably be considered  unlikely to
         reach its destination, such notice shall be valid and effective only if
         it is delivered  personally to such  Warrantholders  or if delivered to
         the  address  for such  Warrantholders  contained  in the  register  of
         Warrants  maintained  by the  Trustee,  by  facsimile or other means of
         prepaid transmitted and recorded communication.

10.3              Ownership and Transfer of Warrants

registered owner of any Warrants as the absolute owner thereof for all purposes,
and the  Corporation  and the  Trustee  shall not be  affected  by any notice or
knowledge  to the  contrary  except  where the  Corporation  or the  Trustee  is
required  to take notice  under any statute or by order of a court of  competent
jurisdiction.  A Warrantholder  shall be entitled to the rights evidenced by its
Warrant  Certificate free from all equities or rights of set off or counterclaim
between  the  Corporation  and the  original or any  intermediate  holder of the
Warrants  and all  persons  may act  accordingly  and the  receipt  of any  such
Warrantholder for the Common Shares which may be acquired pursuant thereto shall
be a good discharge to the  Corporation and the Trustee for the same and neither
the  Corporation nor the Trustee shall be bound to inquire into the title of any
such  holder  except  where the  Corporation  or the Trustee is required to take
notice by statute or by order of a court of competent jurisdiction.

10.4              Evidence of Ownership

(a)      Upon  receipt  of a  certificate  of any bank,  trust  company or other
         depository  satisfactory  to the  Trustee  stating  that  the  Warrants
         specified therein have been deposited by a named person with such bank,
         trust company or other  depository  and will remain so deposited  until
         the expiry of the period  specified  therein,  the  Corporation and the
         Trustee  may  treat  the  person  so  named  as  the  owner,  and  such
         certificate  as sufficient  evidence of the ownership by such person of
         such Warrant  during such period,  for the purpose of any  requisition,
         direction,  consent, instrument or other document to be made, signed or
         given by the holder of the Warrant so deposited.

         the  fact  and  date  of the  signing  of any  requisition,  direction,
         consent,  instrument or other  document by any person (i) the signature
         of  any  officer  of any  bank,  trust  company,  or  other  depository
         satisfactory  to the  Trustee as witness  of such  execution,  (ii) the
         certificate  of any notary public or other  officer  authorized to take
         acknowledgements  of deeds  to be  recorded  at the  place  where  such

         execution thereof, or (iii) a satisfactory  declaration of a witness of
         such execution.

counterparts   together  shall  constitute  one  and  the  same  instrument  and
notwithstanding  their date of execution  they shall be deemed to be dated as of

Share ("Common Share") without nominal or par value of HealthCare  Capital Corp.
(the "Corporation") as such shares were constituted on February 28, 1996.

         subscribed  for, at a price of $1.25 per Common Share if subscribed for
         prior to the Time of Expiry on February 28, 1997,  and  thereafter at a
         price of $1.50 per Common Share if subscribed  for prior to the Time of
         Expiry on the Expiry Date.

                  These  Warrants  shall be deemed to be  surrendered  only upon
personal  delivery  hereof or, if sent by mail or other  means of  transmission,
upon actual receipt thereof by the Trustee at the office referred to above.

                  Upon  surrender  of these  Warrants,  the person or persons in
whose name or names the Common Shares issuable upon exercise of the Warrants are
to be  issued  shall be deemed  for all  purposes  (except  as  provided  in the
Indenture hereinafter referred to) to be the holder or holders of record of such
Common  Shares  and the  Corporation  covenants  that it  will  (subject  to the
provisions of the Indenture)  cause a certificate or  certificates  representing
such  Common  Shares to be  delivered  or mailed to the person or persons at the
address or addresses  specified  in the  Exercise  Form within five (5) Business
Days.

                  The registered holder of these Warrants may acquire any lesser
number of Common  Shares than the number of Common  Shares which may be acquired
for the Warrants  represented by this Warrant  Certificate.  In such event,  the
holder shall be entitled to receive a new Warrant Certificate for the balance of
the Common Shares which may be acquired. No fractional Common Shares or Warrants
will be issued.

                  The Warrants  represented by this certificate are issued under
and pursuant to a Warrant Indenture (hereinafter referred to as the "Indenture")
made as of February 28, 1996 between the Corporation and the Trustee.  Reference
is made to the Indenture  and any  instruments  supplemental  thereto for a full
description  of the  rights of the  holders  of the  Warrants  and the terms and
conditions  upon which the Warrants are, or are to be, issued and held, with the
same  effect  as  if  the  provisions  of  the  Indenture  and  all  instruments
supplemental  thereto were herein set forth.  By acceptance  hereof,  the holder
assents  to all  provisions  of the  Indenture.  Capitalized  terms  used in the
Indenture have the same meaning herein as therein, unless otherwise defined.

                  In the event of any alteration of the Common Shares, including
any subdivision, consolidation or reclassification, and in the event of any form
of  reorganization  of the Corporation,  including any  amalgamation,  merger or
arrangement,  the  holders of Warrants  shall,  upon  exercise  of the  Warrants
following the occurrence of any of those events, be entitled to receive the same
number and kind of securities  that they would have been entitled to receive had
they  exercised  their  Warrants  immediately  prior to the  occurrence of those
events.

                  The registered holder of this Warrant  Certificate may, at any
time prior to the  Expiry  Date,  upon  surrender  hereof to the  Trustee at its
principal office in the City of Calgary,  exchange this Warrant  Certificate for
other Warrant  Certificates  entitling the holder to acquire,  in the aggregate,
the  same  number  of  Common  Shares  as may be  acquired  under  this  Warrant
Certificate.

                                                Alberta and Offshore)

                          PURCHASE OF SPECIAL WARRANTS


TO:               HEALTHCARE CAPITAL CORP.


         1. The undersigned  hereby irrevocably agrees to purchase special share
purchase  warrants (the "Special  Warrants")  of HealthCare  Capital Corp.  (the
"Corporation")  for an  aggregate  consideration  of $ (the  "Purchase  Price"),
representing  a purchase  price of US$1.25 per  Special  Warrant.  Each  Special
Warrant  shall  entitle  the holder to acquire  one (1) Common  Share (a "Common
Share")  of the  Corporation  and one  (1)  Common  Share  Purchase  Warrant  (a
"Warrant")  at no  additional  cost at any  time on or  after  the  issue of the
Special  Warrants,  to and until 4:30 p.m. (Calgary time) (the "Expiry Time") on
the  earlier  of (a) the date which is five (5) days after the date upon which a
receipt  is issued by the  securities  commission  in each of the  Provinces  of
Alberta  and  British  Columbia  (the  "Filing  Provinces")  for the  Prospectus
qualifying  the Common Shares and Warrants to be  distributed on the exercise of
the Special Warrants; and (b) 365 days from the Final Closing Date.

                  The Warrants shall have a term of approximately  two (2) years
and expire on August 31, 1998. Each Warrant entitles the holder to subscribe for
one (1) additional  Common Share of the  Corporation at a subscription  price of
US$2.00 until the expiry thereof.  After the  Registration  Date (defined as the
day on which a receipt is issued for the final  prospectus and all  deficiencies
cleared by the applicable securities commissions) should the closing bid for the
Corporation's common shares be at a price in excess of US$3.00 per common share,
or the  Canadian  equivalent  thereof,  for a period of twenty (20)  consecutive
trading  days (as traded on The Alberta  Stock  Exchange or another  more senior
North American  exchange),  the Corporation  has the option,  on 45 days written
notice to the  undersigned at the address  provided below, to force the exercise
or cancellation of the Warrant.

                  Any Special  Warrants  not  exercised  on or before the Expiry
Time shall be deemed to have been exercised immediately prior to the Expiry Time
without any further action on the part of the holder thereof.

         2. The Special  Warrants  will be duly and  validly  created and issued
pursuant to the terms of a warrant  indenture (the "Special Warrant  Indenture")
to be entered into between the  Corporation  and The R-M Trust Company of Canada
(the "Trustee"),  as trustee at or prior to the closing of the Special Warrants.
The  subscription  proceeds  from  the  sale  of the  Special  Warrants  will be
deposited in the Corporation's  bank accounts and  unconditionally  available to
the Corporation  upon receipt.  The Special  Warrant  Indenture shall be in such
form and  contain  such terms as shall be approved  by the  Corporation  and its
counsel. The Special Warrant Indenture will provide that, in the event a receipt
for the  Prospectus  is not obtained from the  securities  commission or similar
regulatory authority in each of the Filing Provinces on or prior

to the date which is 120 days from the Closing Date,  each holder of the Special
Warrants shall be entitled to receive,  upon the exercise or deemed  exercise of
the  Special  Warrants,  1.1 times the number of Common  Shares and  Warrants to
which he would otherwise be entitled to receive, without additional payment.

         3. By executing this Purchase  Agreement,  the undersigned  represents,
warrants and covenants to the Corporation (and acknowledges that the Corporation
is relying thereon) that:

(a)      it has been  independently  advised as to the  applicable  hold  period
         imposed in respect of the Special  Warrants  (and the Common Shares and

                           undersigned  may not be able to  resell  the  Special

                           upon the exercise  thereof) except in accordance with
                           applicable  securities   legislation  and  regulatory

         jurisdiction  of residence is as stated on the  execution  page of this
         Purchase  Agreement or in Schedule "A" attached  hereto and made a part
         hereof;

                        Securities Act (British Columbia)

                     ACKNOWLEDGEMENT OF INDIVIDUAL PURCHASER


1.       (the    "Purchaser")   has   agreed   to   purchase   from   HealthCare
         -----------------------------------   Capital  Corp.   (the   "Issuer")
         Special           Warrants           at           US$1.25           per
         ------------------------------------------    Special   Warrant.   Each
         Special Warrant is convertible upon exercise,  without further payment,
         into one Common  Share of the Issuer (a "Share")  and one Common  Share
         Purchase Warrant (a "Warrant").  One Warrant is exercisable to purchase
         a further  Common  Share of the  Issuer  for two years from the date of
         issuance of the Special Warrants (the "Closing"), at a price of US$2.00
         during the term  thereof,  subject to an option of forced  exercise  or
         cancellation  given to the Issuer should the closing bid for its common
         shares be in excess of US$3.00, or the Canadian equivalent thereof, for
         a period of twenty  (20)  consecutive  trading  days (as  traded on The
         Alberta Stock Exchange or another more senior North American exchange).
         Such option to be  exercisable  by the Issuer on 45 days written notice
         to the Purchaser.  The Special  Warrants will be deemed to be exercised
         on that day which  falls on the  earlier of one year from the  Closing,
         and the day which is ten  business  days  from the day a receipt  for a
         final prospectus qualifying the proposed distribution of the Shares and
         Warrants to holders of Special Warrants (the "Prospectus") is issued by
         each of the British  Columbia and Alberta  Securities  Commissions.  If
         such  receipts are not issued by that day which falls 120 days from the
         day of the Closing,  then each Special Warrant  outstanding  after that
         day will,  on  exercise  entitle  the holder to  acquire  1.1 times the
         number of Common Shares and Warrants to which he would  otherwise  have
         been entitled to receive,  at no additional  cost. The Special Warrants
         are hereinafter referred to as the "Securities" of the Issuer.

2.       I am  purchasing  the  Securities  as principal  and, on closing of the
         agreement of purchase and sale, I will be the  beneficial  owner of the
         Securities.

             ACKNOWLEDGEMENT OF PURCHASER THAT IS NOT AN INDIVIDUAL


1.       ____________________  (the  "Purchaser")  has agreed to  purchase  from
         HealthCare  Capital Corp. (the "Issuer")  ____________________  Special
         Warrants  at US$1.25  per  Special  Warrant.  Each  Special  Warrant is
         convertible  upon exercise,  without further  payment,  into one Common
         Share of the Issuer (a "Share") and one Common Share  Purchase  Warrant
         (a "Warrant").  One Warrant is exercisable to purchase a further Common
         Share of the  Issuer  for two years  from the date of  issuance  of the
         Special Warrants (the "Closing"), at a price of US$2.00 during the term
         thereof,  subject to an option of forced exercise or cancellation given
         to the Issuer should the closing bid for its common shares be in excess
         of US$3.00, or the Canadian equivalent thereof,  for a period of twenty
         (20) consecutive  trading days (as traded on The Alberta Stock Exchange
         or another  more senior  North  American  exchange).  Such option to be
         exercisable  by the Issuer on 45 days written notice to the Purchaser .
         The Special  Warrants  will be deemed to be exercised on that day which
         falls on the earlier of one year from the Closing, and the day which is
         ten  business  days  from  the day a  receipt  for a  final  prospectus
         qualifying  the  proposed  distribution  of the Shares and  Warrants to
         holders of Special Warrants (the "Prospectus") is issued by each of the
         British Columbia and Alberta Securities  Commissions.  If such receipts
         are not  issued  by that day  which  falls 120 days from the day of the
         Closing,  then each Special Warrant outstanding after that day will, on
         exercise  entitle  the holder to acquire 1.1 times the number of Common
         Shares and Warrants to which he would  otherwise  have been entitled to
         receive,  at no additional  cost. The Special  Warrants are hereinafter
         referred to as the "Securities" of the Issuer.

         company, insurer or portfolio manager acting on behalf of fully managed
         accounts  and is deemed to be  purchasing  as principal  under  section

share  purchase  warrants (the "Special  Warrants") of HealthCare  Capital Corp.
(the "Corporation") for an aggregate  consideration of $ (the "Purchase Price"),
representing  a purchase  price of US$1.25 per  Special  Warrant.  Each  Special
Warrant  shall  entitle  the holder to acquire  one (1) Common  Share (a "Common
Share")  of the  Corporation  and one  (1)  Common  Share  Purchase  Warrant  (a
"Warrant")  at no  additional  cost at any  time on or  after  the  issue of the
Special  Warrants,  to and until 4:30 p.m. (Calgary time) (the "Expiry Time") on
the  earlier  of (a) the date which is five (5) days after the date upon which a

Alberta  and  British  Columbia  (the  "Filing  Provinces")  for the  Prospectus
qualifying  the Common Shares and Warrants to be  distributed on the exercise of
the Special Warrants; and (b) September 23, 1997.

                  The Warrants  shall  expire on August 31,  1998.  Each Warrant
entitles  the holder to  subscribe  for one (1)  additional  Common Share of the
Corporation at a subscription  price of US$2.00 until the expiry thereof.  After
the  Registration  Date (defined as the day on which a receipt is issued for the
final  prospectus  and all  deficiencies  cleared by the  applicable  securities
commissions) should the closing bid for the Corporation's  common shares be at a
price in excess of US$3.00 per common share, or the Canadian equivalent thereof,
for a period of twenty (20)  consecutive  trading days (as traded on The Alberta
Stock Exchange or another more senior North American exchange),  the Corporation
has the option,  on 45 days  written  notice to the  undersigned  at the address
provided below, to force the exercise or cancellation of the Warrant.

                  Any Special  Warrants  not  exercised  on or before the Expiry
Time shall be deemed to have been exercised immediately prior to the Expiry Time
without any further action on the part of the holder thereof.

2. The Special  Warrants will be duly and validly created and issued pursuant to
the  terms of a  warrant  indenture  (the  "Special  Warrant  Indenture")  dated
September 17, 1996 between the  Corporation  and The R-M Trust Company of Canada
(the  "Trustee"),  as trustee.  The  subscription  proceeds from the sale of the
Special  Warrants  will be  deposited  in the  Corporation's  bank  accounts and
unconditionally  available to the Corporation upon receipt.  The Special Warrant
Indenture  provides  that,  in the event a  receipt  for the  Prospectus  is not
obtained from the securities  commission or similar regulatory authority in each
of the Filing Provinces on or prior to the date which is 120 days from the Final
Closing Date (hereinafter defined), each holder of the Special Warrants shall be
entitled  to  receive,  upon the  exercise  or deemed  exercise  of the  Special
Warrants,  1.1 times the  number of Common  Shares  and 1.1 times the  number of
Warrants to which he would otherwise be entitled to receive,  without additional

                            beneficial   purchaser,   it  is   aware   that  the
                            Corporation  is  required by law to  disclose,  on a
                            confidential    basis,    to   certain    regulatory
                            authorities   the   identity   of  each   beneficial
                            purchaser  of  Special  Warrants  for whom it may be
                            acting;

         (g)      it understands and  acknowledges  that the Corporation has the
                  right to instruct the transfer  agent of the Special  Warrants
                  and Common Shares and Warrants not to record a transfer by any
                  person in the United States  without  first being  notified by
                  the  Corporation  that it is satisfied  that such  transfer is
                  exempt  from or not  subject  to  registration  under the U.S.
                  Securities Act and any applicable state securities laws;

         (h)      if required by applicable  securities  legislation,  policy or
                  order or by any securities commission, stock exchange or other
                  regulatory authority,  the undersigned will execute,  deliver,
                  file and  otherwise  assist the  Corporation  in filing,  such
                  reports,  undertakings and other documents with respect to the
                  issue of the  Special  Warrants or Common  Shares  (including,
                  without  limitation,  any undertaking  required by The Alberta
                  Stock Exchange);

         (i)      it understands  that the Corporation is  incorporated  outside
                  the United States,  and there may be material tax consequences
                  to it of the  acquisition,  holding or  disposition  of Common
                  Shares,  Warrants or Common  Shares  issuable upon exercise of
                  the Warrants,  that the Corporation gives no opinion nor makes
                  any representation  with respect to the tax consequences under

                  securities,  and that the  undersigned  should consult its own
                  tax advisors about the United States federal,  state and local
                  and  foreign  tax   consequences  of  acquiring,   holding  or
                  disposing of these securities;

         (j)      it understands and agrees that the financial statements of the
                  Corporation  have been  prepared in  accordance  with Canadian
                  generally accepted accounting principles, which differ in some
                  respects  from United  States  generally  accepted  accounting
                  principles,  and  thus  may  not be  comparable  to  financial
                  statements of United States companies;

         (k)      it  acknowledges  that the  enforcement  by investors of civil
                  liabilities  under the United States federal  securities  laws
                  may be adversely affected by the fact that the Corporation was
                  organized   under  the  laws  of  Alberta,   Canada,   that  a
                  substantial number of the Corporation's officers and directors
                  are not citizens or residents of the United States, and that a
                  substantial portion of the Corporation's assets and the assets
                  of said persons are located outside of the United States.  The
                  undersigned  acknowledges  that there are questions as to: (i)
                  whether  investors  will be able to effect  service of process
                  within the  United  States  upon such  persons;  (ii)  whether
                  investors  will be able to enforce,  in United States  courts,
                  judgements  against  such  persons  obtained  in  such  courts
                  predicated upon the civil liability  provisions of the federal
                  securities  laws;  (iii) whether  appropriate  foreign  courts
                  would enforce  judgements of United States courts  obtained in
                  actions  against  such  persons   predicated  upon  the  civil
                  liability  provisions of the federal securities laws, and (iv)
                  whether the  appropriate  foreign  courts  would  enforce,  in
                  original actions,  liabilities against such persons predicated
                  solely upon the federal securities laws; and

         (l)      this Purchase Agreement has been duly and validly  authorized,
                  executed and  delivered by, and  constitutes  a legal,  valid,
                  binding and enforceable obligation, of the undersigned.

                  The  undersigned   agrees  that  the  above   representations,
warranties  and  covenants  will be true and correct both as of the execution of
this  subscription and as of the Closing Time and will survive the completion of
the issuance of the Special Warrants.

4. The  foregoing  representations,  warranties  and  covenants  are made by the
undersigned  with the  intent  that they be relied  upon by the  Corporation  in
determining the undersigned's suitability as a purchaser of Special Warrants, or
(if  applicable)  the suitability of others on whose behalf it is contracting to
purchase Special Warrants.  The undersigned undertakes to notify the Corporation
immediately of any change in any  representation,  warranty or other information

                  Except as provided for in subsection  5.2(i),  nothing in this
Indenture  or in the  holding of a Special  Warrant or  Warrant  Certificate  or
otherwise,  shall,  in  itself,  confer or be  construed  as  conferring  upon a
Warrantholder any right of interest  whatsoever as a Shareholder or as any other
shareholder of the Corporation, including, but not limited to, the right to vote
at, to receive notice of, or to attend,  meetings of  shareholders  or any other

(a)      No Warrant  Certificate  shall be issued or, if issued,  shall 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 such
         certification  by the  Trustee  upon any Warrant  Certificate  shall be
         conclusive  evidence  as  against  the  Corporation  that  the  Warrant
         Certificate  so certified  has been duly issued  hereunder and that the
         holder is entitled to the benefits hereof.

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

         mutilated  Warrant  Certificate,  or in lieu of and in substitution for
         such lost, destroyed or stolen Warrant Certificate, and the substituted
         Warrant  Certificate shall be in a form approved by the Trustee and the
         Special  Warrants  evidenced  thereby shall be entitled to the benefits
         hereof and shall rank  equally  in  accordance  with its terms with all
         other Special Warrants issued or to be issued hereunder.

(b)      The  applicant for the issue of a new Warrant  Certificate  pursuant to
         this  Section 2.7 shall bear the cost of the issue  thereof and in case

         representing   the  same  aggregate   number  of  Special  Warrants  as
         represented  under the Warrant  Certificate or Warrant  Certificates so
         exchanged.

(b)      Warrant  Certificates may be exchanged only at the Warrant Agency or at
         any other place that is designated by the Corporation with the approval

attorney  duly  appointed  by an  instrument  in writing  in form and  execution
satisfactory  to the Trustee only upon  surrendering  to the Trustee the Warrant
Certificates  representing  the  Special  Warrants  to be  transferred  and upon
compliance with:

               (i)         the conditions herein;

               (ii)        such  reasonable  requirements  as  the  Trustee  may

                          EXERCISE OF SPECIAL WARRANTS


3.1               Method of Exercise of Special Warrants

(a)      The holder of any Special  Warrant  may  exercise  the right  evidenced

         If any of the Common Shares subscribed for are to be issued to a person

         applicable  transfer or similar taxes and the Corporation  shall not be
         required to issue or deliver certificates  evidencing Common Shares and
         Share Purchase Warrants unless or until such  Warrantholder  shall have

(c)      In connection with the exchange of Warrant Certificates and exercise of
         Special  Warrants and  compliance  with such other terms and conditions
         hereof as may be required,  the Corporation has appointed the principal
         offices  of the  Trustee  in  Calgary  as the  agency at which  Warrant
         Certificates  may be  surrendered  for  exchange  or at  which  Special
         Warrants   may  be  exercised   and  the  Trustee  has  accepted   such
         appointment.  The  Corporation  shall give notice to the Trustee of any
         change of the Warrant Agency.

3.2               Effect of Exercise of Special Warrants

(a)      Upon  compliance  by the  holder of any  Warrant  Certificate  with the
         provisions  of Section  3.1,  and  subject to Section  3.3,  the Common
         Shares and Share  Purchase  Warrants  subscribed for shall be deemed to
         have been issued and the person or persons to whom such  Common  Shares
         and Share  Purchase  Warrants  are to be issued shall be deemed to have
         become the holder or holders of record of such Common  Shares and Share
         Purchase Warrants on the Exercise Date unless the transfer registers of
         the Corporation  shall be closed on such date, in which case the Common
         Shares and Share  Purchase  Warrants  subscribed for shall be deemed to
         have been issued and such  person or persons  deemed to have become the
         holder or holders of record of such  Common  Shares and Share  Purchase
         Warrants, on the date on which such transfer registers are reopened.

(b)      Within  five (5)  Business  Days after the  Exercise  Date of a Special
         Warrant as set forth above, the Corporation shall cause to be mailed to
         the person or  persons  in whose  name or names the  Common  Shares and
         Share  Purchase  Warrants  so  subscribed  for  have  been  issued,  as
         specified  in  the  subscription,  at the  address  specified  in  such
         subscription  or, if so  specified  in such  subscription,  cause to be
         delivered  to such  person or persons at the Warrant  Agency  where the
         Warrant   Certificate   was   surrendered,   a  share   certificate  or
         certificates  for the  appropriate  number of Common Shares and a Share
         Purchase  Warrant  certificate or  certificates  for the Share Purchase
         Warrants.

         Corporation  obtaining  a receipt for the  Prospectus  from each of the
         Securities Commissions,  the Corporation may, on the advice of Counsel,
         endorse  the  certificates  representing  the  Common  Shares and Share
         Purchase  Warrants  issued on such  exercise  to the  effect  that such
         shares are subject to trading restrictions under applicable  securities
         legislation,  and prior to the  issuance of any such  certificates  the
         Trustee shall consult with the  Corporation  to determine  whether such
         endorsing or legending is required.

(a)      The  holder  of any  Special  Warrants  may  acquire a number of Common
         Shares  and Share  Purchase  Warrants  less than the  number  which the
         holder is  entitled  to acquire  pursuant  to the  surrendered  Warrant
         Certificate(s)  provided  that,  in no event  shall  fractional  Common
         Shares and Share  Purchase  Warrants  be issued  with regard to Special
         Warrants  exercised.  In the  event of any  acquisition  of a number of
         Common  Shares and Share  Purchase  Warrants less than the number which
         the holder is entitled to acquire,  the holder of the Special  Warrants
         upon  exercise  thereof  shall,  in  addition,  be entitled to receive,
         without charge therefor, a new Warrant Certificate(s) in respect of the
         balance of the Common  Shares and Share  Purchase  Warrants  which such
         holder was  entitled  to acquire  pursuant to the  surrendered  Warrant
         Certificate(s) and which were not then acquired.

(b)      Notwithstanding  anything  herein  contained  including any  adjustment
         provided for in Article 4, the Corporation shall not be required,  upon
         the  exercise of any Special  Warrants,  to issue  fractions  of Common
         Shares and Share Purchase Warrants or to distribute  certificates which
         evidence fractional Common Shares and Share Purchase Warrants.  In lieu
         of fractional Common Shares and Share Purchase Warrants, there shall be
         paid  to the  holder  upon  surrender  of  Warrant  Certificate(s)  for
         exercise of Special  Warrants  pursuant to Section 3.1, within ten (10)
         Business  Days after the  Exercise  Date,  an amount in lawful money of
         Canada  equal  to the then  current  market  value  of such  fractional
         interest  computed  on the  basis of the  closing  price of the  Common
         Shares on The Alberta  Stock  Exchange (or if the Common Shares are not
         then  listed  thereon on such other  exchange  on which such shares are
         listed  or, if not  listed  on any  exchange,  in the  over-the-counter
         market,  as designated by action of the  directors) for the Trading Day
         immediately prior to the Exercise Date or where there is no sale on the
         applicable  exchange or market on the Trading Day immediately  prior to
         the  Exercise  Date,  the average of the last bid and ask prices on the
         applicable exchange or market, provided there shall be no cheque issued
         for less than $5.00.

                                    ARTICLE 4
                      ADJUSTMENT OF NUMBER OF COMMON SHARES
                           AND SHARE PURCHASE WARRANTS


4.1               Adjustment  of  Number  of Common  Shares  and Share  Purchase
                  Warrants

                  The acquisition  rights in effect at any date attaching to the
Special Warrants shall be subject to adjustment from time to time as follows:

(a)      if and  whenever at any time from the date hereof and prior to the Time
         of Expiry, the Corporation shall:

               (i)         subdivide,  redivide or change its outstanding Common
                           Shares into a greater number of shares; or

               (ii)        reduce, combine or consolidate its outstanding Common
                           Shares into a smaller number of shares;

         the number of Common  Shares  and Share  Purchase  Warrants  obtainable
         under each  Special  Warrant  shall be adjusted  immediately  after the
         effective  date of such  subdivision,  redivision,  change,  reduction,
         combination  or  consolidation,  by  multiplying  the  number of Common
         Shares  and  Share  Purchase  Warrants  theretofore  obtainable  on the
         exercise  thereof by a  fraction  of which the  numerator  shall be the
         total number of Common Shares  outstanding  immediately after such date
         and  the  denominator  shall  be the  total  number  of  Common  Shares
         outstanding  immediately  prior to such date. Such adjustment  shall be
         made  successively  whenever any event  referred to in this  subsection
         shall occur;

(b)      if and  whenever at any time from the date hereof and prior to the Time
         of  Expiry,  there is a  reclassification  of the  Common  Shares  or a
         capital  reorganization  of the Corporation  other than as described in
         subsection  4.1(a),  or a consolidation,  amalgamation or merger of the
         Corporation with or into any other body corporate,  trust,  partnership
         or other entity,  or a sale or conveyance of the property and assets of
         the Corporation as an entirety or  substantially  as an entirety to any
         other  body  corporate,   trust,   partnership  or  other  entity,  any
         Warrantholder  who has not exercised its right of acquisition  prior to
         the   effective   date   of  such   reclassification,   reorganization,
         consolidation,  amalgamation,  merger,  sale  or  conveyance  upon  the
         exercise  of such right  thereafter,  shall be  entitled to receive and
         shall accept, in lieu of the number of Common Shares and Share Purchase
         Warrants  then  sought to be  acquired  by it,  the number of shares or
         other  securities  or  property  of  the  Corporation  or of  the  body
         corporate,  trust,  partnership  or other  entity  resulting  from such
         merger,  amalgamation  or  consolidation,  or to  which  such  sale  or
         conveyance  may be made,  as the case may be,  that such  Warrantholder
         would have been entitled to receive on such  reclassification,  capital
         reorganization,    consolidation,   amalgamation,   merger,   sale   or
         conveyance,  if, on the record date or the effective  date thereof,  as
         the case may be, the  Warrantholder  had been the registered  holder of
         the number of Common Shares and Share  Purchase  Warrants  sought to be
         acquired by it. If determined appropriate by the Trustee to give effect
         to or to  evidence  the  provisions  of  this  subsection  4.1(b),  the
         Corporation,   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  reclassification,  reorganization,
         consolidation,  amalgamation, merger, sale or conveyance, 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 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 Corporation and the
         Trustee pursuant to the provisions of this subsection 4.1(b) shall be a
         supplemental  indenture  entered  into  pursuant to the  provisions  of
         Article 8 hereof.  Any indenture  entered into between the Corporation,
         any successor to the  Corporation 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 provide in this Section 4.1 and which shall apply to
         successive    reclassification,     reorganizations,     amalgamations,
         consolidations, mergers, sales or conveyances; and

(c)      the adjustments  provided for in this Article 4 in the number of Common
         Shares and Share Purchase  Warrants and classes of securities which are
         to be received  on the  exercise of Special  Warrants  are  cumulative.
         After any adjustment pursuant to this Section,

         the term "Common  Shares" and "Share  Purchase  Warrants" where used in
         this Indenture  shall be interpreted to mean securities of any class or
         classes which, as a result of such adjustment and all prior adjustments
         pursuant to this Section, the Warrantholder is entitled to receive upon
         the exercise of its Special  Warrant,  and the number of Common  Shares
         and Share Purchase Warrants  indicated by any exercise made pursuant to
         a Special  Warrant  shall be  interpreted  to mean the number of Common
         Shares and Share  Purchase  Warrants or other  property or securities a
         Warrantholder  is entitled to receive,  as a result of such  adjustment
         and all  prior  adjustments  pursuant  to this  Section,  upon the full
         exercise of a Special Warrant.

4.2               Entitlement to Common Shares and Share Purchase Warrants
                  on Exercise of Special 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 Special 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 Special Warrant.

4.3               No Adjustment for Stock Options

                  Anything in this Article 4 to the contrary notwithstanding, no
adjustment  shall be made in the  acquisition  rights  attached  to the  Special
Warrants if the issue of Common Shares and Share Purchase Warrants is being made
pursuant to this  Indenture or pursuant to any stock option,  stock  purchase or
employee  RRSP plan in force from time to time for  officers or employees of the
Corporation.

4.4               Determination by Corporation's Auditors

                  In the  event of any  question  arising  with  respect  to the
adjustments  provided for in this Article 4 such question shall be  conclusively
determined by the Corporation's  Auditors who shall have access to all necessary
records of the  Corporation,  and such  determination  shall be binding upon the
Corporation,  the Trustee,  all  Warrantholders and all other persons interested
therein.

4.5               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 Special  Warrants,  including the number of Common Shares and Share Purchase
Warrants which are to be received upon the

exercise thereof,  the Corporation shall take any corporate action which may, in
the opinion of counsel,  be necessary in order that the Corporation 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 holders of such Special
Warrants are entitled to receive on the full exercise thereof in accordance with
the provisions hereof.

4.6               Certificate of Adjustment

                  The Corporation  shall from time to time immediately after the
occurrence of any event which requires an adjustment or readjustment as provided
in Article 4, deliver a certificate of the Corporation to the Trustee specifying
the  nature of the event  requiring  the same and the  amount of the  adjustment
necessitated  thereby  and  setting  forth in  reasonable  detail  the method of
calculation  and  the  facts  upon  which  such  calculation  is  based,   which
certificate  shall be supported by a certificate of the  Corporation's  auditors
verifying such calculation.

4.7               Notice of Special Matters

                  The  Corporation  covenants  with the Trustee that, so long as
any Special 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  Special  Warrants)  to all or
substantially  all the holders of its  outstanding  Common  Shares.  Such notice
shall specify the  particulars of such event and the record date for such event,
provided  that the  Corporation  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 case not
less than fourteen (14) days prior to such applicable record date.

4.8               No Action after Notice

                  The  Corporation  covenants  with the Trustee that it will not
close its transfer books or take any other corporate  action which might deprive
the holder of a Special  Warrant of the  opportunity  to  exercise  its right of
acquisition  pursuant  thereto during the period of fourteen (14) days after the
giving of the certificate or notices set forth in Section 4.6 and 4.7.

4.9               Protection of Trustee

                  Except as provided in Section 9.2, the Trustee:

(a)      shall  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

         adjustment  when made, or with respect to the method employed in making
         the same;

(b)      shall not be accountable  with respect to the validity or value (or the
         kind or amount) of any Common Shares or Share  Purchase  Warrants or 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
         Special Warrant;

(c)      shall not be responsible  for any failure of the  Corporation to issue,
         transfer  or  deliver  Common  Shares  or Share  Purchase  Warrants  or
         certificates  for the same upon the  surrender of any Special  Warrants
         for the purpose of the exercise of such rights or to comply with any of
         the covenants contained in this Article; and

(d)      shall not incur any liability or responsibility whatsoever or be in any
         way responsible  for the  consequences of any breach on the part of the

         herein  contained  or of any  acts of the  agents  or  servants  of the
         Corporation.

such Special  Warrants are then  obtainable,  plus reasonable costs of purchase,

Corporation,  in its sole discretion,  may determine.  Any Warrant  Certificates

         Stock Exchange;

(f)      it will make all requisite filings under applicable Canadian securities
         legislation  including those necessary to remain a reporting issuer not

         the Trustee  and to each  holder of Special  Warrants at the address of
         such holder  appearing in the register of Special  Warrants  maintained
         pursuant to this  Special  Warrant  Indenture  within five (5) Business
         Days of the receipt  for a  Prospectus  in all of the Filing  Provinces
         advising  of the  issuance  of a  receipt  for  the  Prospectus  by the
         Securities  Commissions and of the date upon which the Special Warrants
         will be deemed to be exercised and expire;

                                   ENFORCEMENT

6.4               Waiver of Default

                  Upon the happening of any default hereunder:

(a)      the  holders  of  not  less  than  51%  of the  Special  Warrants  then
         outstanding shall have power (in addition to the powers  exercisable by
         extraordinary resolution as provided in Section 7.10) by requisition in
         writing to instruct the Trustee to waive any default  hereunder and the
         Trustee  shall   thereupon  waive  the  default  upon  such  terms  and
         conditions as shall be prescribed in such requisition; or

(b)      the Trustee shall have power to waive any default  hereunder  upon such
         terms and  conditions  as the Trustee on advice of its counsel may deem

         or adequate provision made therefor;

provided  that no delay or omission of the Trustee or of the  Warrantholders  to
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 7
                           MEETINGS OF WARRANTHOLDERS

7.1               Right to Convene Meetings

                  The Trustee  may at any time and from time to time,  and shall
on  receipt  of a written  request of the  Corporation  or of a  Warrantholders'
Request and upon being indemnified and funded to its reasonable  satisfaction by
the Corporation or by the Warrantholders  signing such  Warrantholders'  Request
against  the cost which may be  incurred  in  connection  with the  calling  and
holding of such meeting,  convene a meeting of the Warrantholders.  In the event
of the  Trustee  failing  to so  convene a meeting  within  seven (7) days after
receipt of such  written  request  of the  Corporation  or such  Warrantholders'
Request  and   indemnity   given  as   aforesaid,   the   Corporation   or  such
Warrantholders, as the case may be, may convene such meeting. Every such meeting
shall be held in the City of Calgary or at such other  place as may be  approved
or determined by the Trustee.

7.2               Notice

                  At  least  ten (10)  days'  prior  notice  of any  meeting  of
Warrantholders  shall be given to the  Warrantholders in the manner provided for
in Section  10.2 and a copy of such notice  shall be sent by mail to the Trustee
(unless  the  meeting has been  called by the  Trustee)  and to the  Corporation
(unless the meeting has been called by the Corporation). Such notice shall state
the time when and the place where the meeting is to be held, shall 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 shall not be necessary  for any such
notice  to set out the  terms of any  resolution  to be  proposed  or any of the
provisions of this Article 7.

7.3               Chairman

                  An individual (who need not be a Warrantholder)  designated in
writing by the Trustee  shall be chairman of the meeting and if no individual is
so designated,  or if the individual so designated is not present within fifteen
(15)  minutes  from  the  time  fixed  for  the  holding  of  the  meeting,  the
Warrantholders  present  in  person or by proxy  shall  choose  some  individual
present to be chairman.

7.4               Quorum

                  Subject to the  provisions  of Section 7.11, at any meeting of
the Warrantholders a quorum shall consist of Warrantholders present in person or
by proxy and entitled to purchase at least 25% of the aggregate number of Common
Shares  which could be acquired  pursuant  to all the then  outstanding  Special
Warrants,  provided  that at least two  persons  entitled  to vote  thereat  are
personally  present.  If a quorum of the  Warrantholders  shall  not be  present
within  thirty (30)  minutes  from the time fixed for holding any  meeting,  the
meeting,  if summoned by the  Warrantholders  or on a  Warrantholders'  Request,
shall be dissolved;  but in any other case the meeting shall be adjourned to the
same day in the next week (unless such day is not a Business  Day, in which case
it shall be adjourned to the next  following  Business Day) at the same time and
place and no notice  of the  adjournment  need be  given.  Any  business  may be
brought before or dealt with at an adjourned meeting which might have been dealt
with at the original  meeting in accordance with the notice calling the same. No
business  shall be transacted  at any meeting  unless a quorum be present at the
commencement of business. At the adjourned meeting the Warrantholders present in
person or by proxy shall form a quorum and may  transact  the business for which
the  meeting  was  originally  convened,  notwithstanding  that  they may not be
entitled to acquire at least 25% of the aggregate  number of Common Shares which
may be acquired pursuant to all then outstanding Warrants.

7.5               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 any such
meeting,  and no notice of such adjournment need be given except such notice, if
any, as the meeting may prescribe.

7.6               Show of Hands

                  Every question  submitted to a meeting shall be decided in the
first  place by a majority  of the votes  given on a show of hands  except  that
votes on an extraordinary  resolution  shall be given in the manner  hereinafter
provided.  At any  such  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 shall be conclusive evidence of the fact.

7.7               Poll and Voting

                  On every extraordinary  resolution,  and on any other question
submitted  to a meeting  and after a vote by show of hands when  demanded by the
chairman  or by one or more of the  Warrantholders  acting in person or by proxy
and entitled to acquire in the aggregate at least 5% of the aggregate  number of
Common Shares which could be acquired  pursuant to all the Special Warrants then
outstanding,  a poll shall be taken in such manner as the chairman shall direct.
Questions other than those required to be determined by extraordinary resolution
shall be decided by a majority of the votes cast on the poll.

                  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,  shall have one vote.  On a poll,  each  Warrantholder
present in person or  represented  by a proxy duly  appointed by  instrument  in
writing  shall be  entitled  to one vote in respect of each whole  Common  Share
which he is  entitled  to acquire  pursuant  to the  Special  Warrant or Special
Warrants then held or  represented  by it. A proxy need not be a  Warrantholder.
The Chairman of any meeting shall be entitled,  both on a show of hands and on a
poll, to vote in respect of the Special Warrants, if any, held or represented by
him.

7.8               Regulations

                  The  Trustee,  or the  Corporation  with the  approval  of the
Trustee,  may from time to time make and from time to time vary such regulations
as it shall think fit for:

(a)      the  setting  of the  record  date for a  meeting  for the  purpose  of

         depository  satisfactory  to  the  Trustee  stating  that  the  Warrant
         Certificates  specified  therein have been deposited with it by a named
         person and will remain on deposit until after the meeting, which voting
         certificate  shall  entitle the persons named therein to be present and
         vote at any such meeting and at any adjournment thereof or to appoint a
         proxy  or  proxies  to  represent  them  and  vote for them at any such
         meeting and at any adjournment  thereof in the same manner and with the
         same effect as though the persons so named in such voting  certificates
         were the actual bearers of the Warrant Certificates specified therein;

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

(d)      the deposit of voting  certificates and 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 such  instruments
         appointing proxies to be mailed or sent by facsimile before the meeting
         to the  Corporation 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

         of business thereat.

                  Any regulations so made shall be binding and effective and the
votes given in accordance therewith shall be valid and shall be counted. Save as
such  regulations  may provide,  the only persons who shall be recognized at any
meeting as a Warrantholder,  or be entitled to vote or be present at the meeting
in respect thereof  (subject to Section 7.9), shall be  Warrantholders  or their
counsel, or proxies of Warrantholders.

7.9               Corporation and Trustee May be Represented

                  The   Corporation  and  the  Trustee,   by  their   respective
directors,  officers and employees,  and the counsel for the Corporation and for
the  Trustee  may attend any  meeting  of the  Warrantholders,  but shall not be
entitled to vote  thereat,  whether in respect of any Special  Warrants  held by

         Corporation.


7.11              Meaning of Extraordinary Resolution

(a)      The expression  "extraordinary  resolution" when used in this Indenture
         means,  subject as  hereinafter  provided in this  Section  7.11 and in
         Section 7.14, a resolution proposed at a meeting of Warrantholders duly
         convened for that purpose and held in accordance with the provisions of
         this  Article  7 at which  there  are  present  in  person  or by proxy
         Warrantholders entitled to acquire at least 25% of the aggregate number
         of  Common  Shares  which  may be  acquired  pursuant  to all the  then
         outstanding  Special  Warrants and passed by the  affirmative  votes of
         Warrantholders  entitled  to  acquire  not  less  than  66  2/3% of the
         aggregate number of Common Shares which may be acquired pursuant to all
         the then outstanding  Special  Warrants  represented at the meeting and
         vote on the poll upon such resolution.

(b)      If,  at the  meeting  at which  an  extraordinary  resolution  is to be
         considered,  Warrantholders  entitled  to  acquire  at least 25% of the
         aggregate number of Common Shares which may be acquired pursuant to all
         the then  outstanding  Special Warrants are not present in person or by
         proxy  within  thirty (30)  minutes  after the time  appointed  for the
         meeting,  then  the  meeting,  if  convened  by  Warrantholders  or  on
         Warrantholders'  Request,  shall be  dissolved;  but in any other shall
         stand  adjourned to such day, being not less than fifteen nor more than
         sixty (60) days later,  and to such place and time as  appointed by the
         chairman.  Not less than ten (10) days' prior  notice shall be given of
         the time and place of such adjourned meeting in the manner provided for
         in Section 10.2. Such notice shall state that at the adjourned  meeting
         the  Warrantholders  present in person or by proxy  shall form a quorum
         but it shall 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
         shall form a quorum and may transact the business for which the meeting
         was  originally  convened and a resolution  proposed at such  adjourned
         meeting and passed by the  requisite  vote as  provided  in  subsection
         7.11(a) shall be an extraordinary resolution within the meaning of this
         Indenture  notwithstanding  that Warrantholders  entitled to acquire at
         least  25% of the  aggregate  number  of  Common  Shares  which  may be
         acquired pursuant to all the then outstanding  Special Warrants are not
         present in person or by proxy at such adjourned meeting.

extraordinary resolution or otherwise may be exercised from time to time and the
exercise  of any one or more of such  powers or any  combination  of powers from

time to time.

         the Corporation from any of the obligations, conditions or restrictions
         herein contained, provided that such modification or relief shall be or
         become operative or effective only if, in the opinion of the Trustee on
         advice of its counsel, such modification or relief in no way prejudices
         any of the rights of the Warrantholders or of the Trustee, and provided
         further  that the Trustee may in its sole  discretion  decline to enter
         into any such  supplemental  indenture  which  in its  opinion  may not
         afford  adequate  protection  to the Trustee when the same shall become
         operative; and

(g)      for  any  other  purpose  not  inconsistent  with  the  terms  of  this

transfer  of the  undertaking  or assets of the  Corporation  as an  entirety or
substantially as an entirety to another Corporation  ("successor  Corporation"),
the  successor  Corporation  resulting  from such  consolidation,  amalgamation,

supplemental  indenture  satisfactory  in form to the Trustee and  executed  and
delivered to the Trustee,  the due and punctual  performance  and  observance of
each and every  covenant  and  condition of this  Indenture to be performed  and

                             CONCERNING THE TRUSTEE

9.1               Trust Indenture Legislation

(a)      If and to the  extent  that any  provision  of this  Indenture  limits,
         qualifies  or  conflicts  with a mandatory  requirement  of  Applicable
         Legislation, such mandatory requirement shall prevail.

(b)      The  Corporation  and the Trustee agree that each will, at all times in
         relation  to this  Indenture  and any  action  to be  taken  hereunder,
         observe and comply with and be entitled to the  benefits of  Applicable
         Legislation.

9.2               Rights and Duties of Trustee

(a)      In the exercise of the rights and duties prescribed or conferred by the
         terms of this  Indenture,  the Trustee  shall  exercise  that degree of
         care,  diligence  and skill that a  reasonably  prudent  trustee  would
         exercise in comparable  circumstances.  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 willful
         misconduct or bad faith.

(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   hereunder   shall   be   conditional   upon  the
         Warrantholders  furnishing,  when  required  by notice by the  Trustee,
         sufficient  funds to  commence  or to  continue  such  act,  action  or
         proceeding and an indemnity  reasonably  satisfactory to the Trustee to
         protect and to 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  shall require the Trustee to expend or to risk its own
         funds or otherwise to incur  financial  liability in the performance of
         any of its  duties or in the  exercise  of any of its  rights or powers
         unless indemnified as aforesaid.

(c)      The  Trustee  may,  before   commencing  or  at  any  time  during  the
         continuance  of  any  such  act,  action  or  proceeding,  require  the
         Warrantholders,  at whose  instance  it is acting to  deposit  with the
         Trustee the Special  Warrants held by them, for which Special  Warrants
         the Trustee shall issue receipts.

(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 Applicable  Legislation,  of this
         Section 9.2 and of Section 9.3

9.3               Evidence, Experts and Advisers

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

(b)      In the exercise of its rights and duties hereunder, 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  in  statutory  declarations,
         opinions,  reports,  written  requests,  consents,  or  orders  of  the
         Corporation,   certificates   of  the  Corporation  or  other  evidence
         furnished to the Trustee pursuant to a request of the Trustee, provided
         that such evidence  complies with  Applicable  Legislation and that the
         Trustee  complies  with  Applicable  Legislation  and that the  Trustee
         examines the same and determines  that such evidence  complies with the
         applicable requirements of this Indenture.

(c)      Whenever  it  is  provided  in  this  Indenture  or  under   Applicable
         Legislation  that  the  Corporation  shall  deposit  with  the  Trustee
         resolutions, certificates, reports, opinions, requests, orders or other
         documents,  it is intended  that the trust,  accuracy and good faith on
         the  effective  date thereof and the facts and  opinions  stated in all
         such  documents so  deposited  shall,  in each and every such case,  be
         conditions  precedent  to the  right  of the  Corporation  to have  the
         Trustee take the action to be based thereon.

(d)      Proof  of the  execution  of an  instrument  in  writing,  including  a
         Warrantholders'  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  acknowledged  to  it  the
         execution thereof, or by an affidavit of a witness to such execution or
         in any other manner which the Trustee may consider adequate.

(e)      The Trustee may employ or retain such Counsel, accountants,  appraisers
         or other  experts or  advisers  as it may  reasonably  require  for the
         purpose of  discharging  its duties  hereunder  and may pay  reasonable
         remuneration  for all  services so  performed  by any of them,  without
         taxation of costs of any Counsel,  and shall not be responsible for any
         misconduct  or  negligence  on the part of any such experts or advisers
         who have been appointed with due care by the Trustee.

9.4               Documents, Monies, etc.  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 Canadian chartered bank or
deposited for safekeeping with any such bank. Unless herein otherwise  expressly
provided, any monies so held pending the application or withdrawal thereof under
any  provisions of this Indenture may be deposited in the name of the Trustee in
any  Canadian  chartered  bank at the rate of interest  (if any) then current on
similar deposits or, with the consent of the Corporation,  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; or
(ii) invested in securities issued or guaranteed by the

Government of Canada or a province  thereof or in obligations  maturing not more
than sixty days from the date of investment,  of any Canadian  chartered bank or
loan or trust company. Unless the Corporation shall be in default hereunder, all
interest or other income received by the Trustee in respect of such deposits and
investments shall belong to the Corporation.

9.5               Actions by Trustee to Protect Interest

                  The Trustee shall 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 Warrantholders.

9.6               Trustee Not Required to Give Security

                  The Trustee shall 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.

9.7               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  shall not be liable for or by reason of any  statements of
         fact or  recitals  in this  Indenture  or in the  Warrant  Certificates
         (except  the  representation   contained  in  Section  9.9  or  in  the
         certificate of the Trustee on the Warrant  Certificates) or be required
         to verify the same,  but all such  statements or recitals are and shall
         be deemed to be made by the Corporation;

(b)      nothing herein  contained shall 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
         hereto;

(c)      the Trustee  shall not be bound to give notice to any person or persons
         of the execution hereof;

(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 Corporation of any of the covenants  herein  contained or of any
         acts of any directors,  officers,  employees, agents or servants of the
         Corporation; and

                                                      - 35 -

(e)      without  limiting any  protection or indemnity of the Trustee under any
         other provision  hereof,  or otherwise at law, the  Corporation  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,  including 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 willful  misconduct  of the Trustee.  This
         provision  shall survive the  resignation  or removal of the Trustee or
         the termination of this Warrant Indenture.

9.8               Replacement of Trustee; Successor by Merger

(a)      The  Trustee  may resign its trust and be  discharged  from all further
         duties and  liabilities  hereunder,  subject to this  Section  9.8,  by
         giving to the  Corporation not less than ninety (90) days' prior notice
         in writing or such shorter prior notice as the  Corporation  may accept
         as sufficient.  The  Warrantholders  by extraordinary  resolution shall
         have power at any time to remove the existing  Trustee and to appoint a
         new Trustee.  In the event of the Trustee resigning or being removed as
         aforesaid or being dissolved, becoming bankrupt, going into liquidation
         or otherwise  becoming  incapable of acting hereunder,  the Corporation
         shall forthwith  appoint a new trustee unless a new trustee has already
         been appointed by the  Warrantholders;  failing such appointment by the
         Corporation,  the retiring Trustee or any  Warrantholder may apply to a
         justice of the Court of  Queen's  Bench of the  Province  of Alberta on
         such notice as such justice may direct,  for the  appointment  of a new
         trustee;  but any new trustee so appointed by the Corporation or by the
         Court shall be subject to removal as aforesaid  by the  Warrantholders.
         Any new trustee appointed under any provision of this Section 9.8 shall
         be a Corporation authorized to carry on the business of a trust company
         in  the  Province  of  Alberta  and,  if  required  by  the  Applicable
         Legislation for any other provinces,  in such other  provinces.  On any
         such  appointment the new trustee shall be vested with the same powers,
         rights,  duties and responsibilities as if it had been originally named
         herein as Trustee hereunder.

(b)      Upon the  appointment of a successor  trustee,  the  Corporation  shall
         promptly notify the  Warrantholders  thereof in the manner provided for
         in Section 10.2 hereof.

(c)      Any  corporation  into or with  which  the  Trustee  may be  merged  or
         consolidated or amalgamated,  or any corporation resulting therefrom or
         any  corporation  succeeding to the trust business of the Trustee shall
         be the successor to the Trustee hereunder without

         any further act on its part or any of the parties hereto, provided that
         such  corporation  would be  eligible  for  appointment  as a successor
         trustee under subsection 9.8(a).

(d)      Any Warrant  Certificates  certified but not delivered by a predecessor
         trustee may be  certified by the  successor  trustee in the name of the
         predecessor or successor trustee.

9.9               Conflict of Interest

(a)      The Trustee represents to the Corporation that at the time of execution
         and delivery hereof no material conflict of interest exists between its
         role as a  trustee  hereunder  and its role in any other  capacity  and
         agrees that in the event of a material  conflict  of  interest  arising
         hereafter it will,  within ninety (90) days after  ascertaining that it
         has such material  conflict of interest,  either  eliminate the same or
         assign its trust  hereunder  to a  successor  trustee  approved  by the
         Corporation  and  meeting  the  requirements  set  forth in  subsection
         9.8(a).

         Notwithstanding the foregoing  provisions of this subsection 9.9(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 9.9(a), the Trustee, in its personal or any other
         capacity,  may buy, lend upon and deal in securities of the Corporation
         and generally may contract and enter into financial  transactions  with
         the  Corporation  or any  Subsidiary of the  Corporation  without being
         liable to account for any profit made thereby.

9.10              Acceptance of Trust

                  The  Trustee  hereby  accepts  the  trusts  in this  Indenture
declared  and  provided  for and agrees to  perform  the same upon the terms and
conditions herein set forth.

9.11              Trustee Not to be Appointed Receiver

                  The Trustee and any person related to the Trustee shall not be
appointed a receiver, a receiver and manager or liquidator of all or any part of
the assets or undertaking of the Corporation.

         notice.

(b)      The  Corporation  or the Trustee,  as the case may be, may from time to
         time notify the other in the manner provided in subsection 10.1(a) of a
         change of address  which,  from the  effective  date of such notice and

         unlikely  to reach  its  destination,  such  notice  shall be valid and
         effective  only if it is delivered to the named officer of the party to
         which it is  addressed  or,  if it is  delivered  to such  party at the

(a)      Any notice to the Warrantholders under the provisions of this Indenture
         shall be valid and effective if sent by facsimile or letter or circular
         through  the  ordinary  post  addressed  to such  holders at their post
         office addresses appearing on the register  hereinbefore  mentioned and
         shall be deemed to have been effectively  given on the date of delivery
         or, if mailed,  five (5) Business Days following  actual posting of the
         notice.

(b)      If, by reason of a strike,  lockout or other work  stoppage,  actual or
         threatened,  involving postal employees,  any notice to be given to the
         Warrantholders  hereunder  could  reasonably be considered  unlikely to
         reach its destination, such notice shall be valid and effective only if
         it is delivered  personally to such  Warrantholders  or if delivered to
         the  address  for such  Warrantholders  contained  in the  register  of
         Special Warrants maintained by the Trustee, by facsimile or other means
         of prepaid transmitted and recorded communication.

10.3              Ownership and Transfer of Special Warrants

                  The  Corporation  and the  Trustee  may  deem  and  treat  the
registered  owner of any Special  Warrants as the absolute owner thereof for all
purposes,  and the  Corporation  and the  Trustee  shall not be  affected by any
notice or knowledge to the contrary  except where the Corporation or the Trustee
is required to take notice under any statute or by order of a court of competent
jurisdiction.  A Warrantholder  shall be entitled to the rights evidenced by its
Warrant  Certificate free from all equities or rights of set off or counterclaim
between  the  Corporation  and the  original or any  intermediate  holder of the
Special Warrants and all persons may act accordingly and the receipt of any such
Warrantholder  for the Common Shares and Share  Purchase  Warrants  which may be
acquired  pursuant  thereto shall be a good discharge to the Corporation and the
Trustee for the same and neither the  Corporation nor the Trustee shall be bound
to inquire into the title of any such holder except where the Corporation or the
Trustee  is  required  to take  notice  by  statute  or by  order  of a court of
competent jurisdiction.


10.4              Evidence of Ownership

(a)      Upon  receipt  of a  certificate  of any bank,  trust  company or other
         depository  satisfactory  to  the  Trustee  stating  that  the  Special
         Warrants  specified  therein have been deposited by a named person with
         such  bank,  trust  company  or other  depository  and will  remain  so
         deposited  until  the  expiry  of the  period  specified  therein,  the
         Corporation and the Trustee may treat the person so named as the owner,
         and such  certificate  as sufficient  evidence of the ownership by such
         person of such Special  Warrant during such period,  for the purpose of
         any requisition, direction, consent, instrument or other document to be
         made,  signed  or  given  by the  holder  of  the  Special  Warrant  so
         deposited.

(b)      The  Corporation  and the Trustee may accept as sufficient  evidence of
         the  fact  and  date  of the  signing  of any  requisition,  direction,
         consent,  instrument or other  document by any person (i) the signature
         of  any  officer  of any  bank,  trust  company,  or  other  depository
         satisfactory  to the  Trustee as witness  of such  execution,  (ii) the
         certificate  of any notary public or other  officer  authorized to take
         acknowledgements  of deeds  to be  recorded  at the  place  where  such
         certificate  is made that the person  signing  acknowledged  to him the
         execution thereof, or (iii) a satisfactory  declaration of a witness of
         such execution.


10.5              Counterparts

                  This Indenture may be executed in several  counterparts,  each
of  which  when  so  executed  shall  be  deemed  to be  an  original  and  such
counterparts   together  shall  constitute  one  and  the  same  instrument  and
notwithstanding  their date of execution  they shall be deemed to be dated as of
the date hereof.

10.6              Satisfaction and Discharge of Indenture

                  Upon the earlier of:

(a)      the date by which  there shall have been  delivered  to the Trustee for
         exercise or destruction all Warrant Certificates  theretofore certified
         hereunder; or

(b)      the Time of Expiry;

equitable right, remedy or claim under this

(a)      duly completing and executing the Exercise Form attached hereto; and

(b)      surrendering this Special Warrant  Certificate to The R-M Trust Company
         (the  "Trustee") at the principal  office of the Trustee in the City of

                  These Special  Warrants shall be deemed to be surrendered only
upon  personal   delivery  hereof  or,  if  sent  by  mail  or  other  means  of
transmission,  upon actual receipt thereof by the Trustee at the office referred
to above.

                  Upon  surrender  of these  Special  Warrants,  the  person  or
persons  in whose name or names the Common  Shares and Share  Purchase  Warrants
issuable upon exercise of the Special  Warrants are to be issued shall be deemed

Exercise Form attached hereto and surrendering this Special Warrant  Certificate
to the Trustee at the principal offices of the Trustee in Calgary, Alberta.

                  The  Special  Warrants  represented  by this  certificate  are
issued under and pursuant to a Special Warrant Indenture  (hereinafter  referred
to as the "Indenture") made as of September 17, 1996 between the Corporation and
the Trustee. Reference is made to the Indenture and any instruments supplemental
thereto  for a full  description  of the rights of the  holders  of the  Special
Warrants and the terms and  conditions  upon which the Special  Warrants are, or
are to be,  issued and held,  with the same effect as if the  provisions  of the
Indenture and all  instruments  supplemental  thereto were herein set forth.  By
acceptance  hereof,  the holder  assents  to all  provisions  of the  Indenture.
Capitalized terms used in the Indenture have the same meaning herein as therein,
unless otherwise defined.

                  In the event of any alteration of the Common Shares, including
any subdivision, consolidation or reclassification, and in the event of any form
of  reorganization  of the Corporation,  including any  amalgamation,  merger or
arrangement, the holders of Special Warrants shall, upon exercise of the Special
Warrants following the occurrence of any of those events, be entitled to receive
the same  number and kind of  securities  that they would have been  entitled to
receive had they  exercised  their  Special  Warrants  immediately  prior to the
occurrence of those events.

                  The registered holder of this Special Warrant Certificate may,
at any time prior to the Expiry Date,  upon  surrender  hereof to the Trustee at
its  principal  office in the City of Calgary,  exchange  this  Special  Warrant
Certificate  for other  Special  Warrant  Certificates  entitling  the holder to
acquire,  in the aggregate,  the same number of Common Shares and Share Purchase
Warrants as may be acquired under this Special Warrant Certificate.

                  The holding of the Special Warrants  evidenced by this Special
Warrant  Certificate shall not constitute the holder hereof a shareholder of the
Corporation  or entitle the holder to any right or  interest in respect  thereof
except as  expressly  provided  in the  Indenture  and in this  Special  Warrant
Certificate.

                  The Indenture  provides  that all holders of Special  Warrants
shall be bound by any  resolution  passed at a meeting  of the  holders  held in
accordance  with the provisions of the Indenture and  resolutions  signed by the
holders of Special  Warrants  entitled  to acquire a  specified  majority of the
Common  Shares which may be acquired  pursuant to all then  outstanding  Special
Warrants.

                  The  Special  Warrants   evidenced  by  this  Special  Warrant
Certificate  may be  transferred  on the  register  kept at the  offices  of the
Trustee by the registered holder hereof or

purpose  whatever  unless and until it has been certified by or on behalf of the
Trustee.

Warrant  Certificate to be signed by its duly authorized officer as of September

                                ISSUE OF WARRANTS

2.1               Issue of Warrants

(a)      5,760,000  Warrants,  each of which  entitles  the  holder  thereof  to
         acquire one (1) Common Share,  subject to adjustment in accordance with
         Article 4 hereof, are hereby created and authorized to be issued.

(b)      The  Warrants  shall be issued  from time to time upon the  holders  of
         Special Warrants duly exercising such Special Warrants  pursuant to the
         Special  Warrant  Indenture  and  effective  the date the  Warrants are
         deemed to be issued  pursuant to such exercise in  accordance  with the
         Special Warrant Indenture.

(c)      The  Warrant   Certificates   (including  all  replacements  issued  in
         accordance with this Indenture)  shall be substantially in the form set
         out in Schedule "A" hereto,  shall be dated as of the Issue Date, shall
         bear such  distinguishing  letters and numbers as the Corporation  may,
         with the approval of the Trustee,  prescribe,  and shall be issuable in
         any denomination excluding fractions.

(d)      The Warrant  Certificates  may be engraved,  printed,  lithographed  or
         partly  in one  form and  partly  in  another  as the  Corporation  may
         determine.  No change in the Warrant  Certificates shall be required by
         reason of any  adjustment  made  pursuant to Article 4 in the number or
         class of  Common  Shares  or  other  securities  to  which a holder  is
         entitled pursuant to the exercise of the Warrants.

2.2               Form and Terms of Warrants

(a)      Each whole Warrant  authorized to be issued hereunder shall entitle the
         holder thereof, upon exercise, to acquire one (1) Common Share, subject
         to adjustment in  accordance  with Article 4 hereof,  at any time after
         the Issue Date until the Time of Expiry,  except as otherwise  provided
         for in this  Section  2.2.  The  price  at  which a  Warrantholder  may
         purchase  Common Shares upon the exercise of the Warrants  shall be the
         Exercise Price.

(b)      In the  event  that  the  closing  bid for  the  Common  Shares  on the
         principal  stock exchange on which the Common Shares are listed,  or if
         the Common Shares are not listed on The Alberta Stock  Exchange then on
         such other more senior stock  exchange upon which the Common Shares are
         listed,  is at a price in excess of US$3.00  per Common  Share,  or the
         Canadian  equivalent  thereof,  for a period of twenty (20) consecutive
         trading days, the Corporation, at the sole discretion of its directors,
         shall have the right to provide  written  notice to the  Warrantholders
         advising  them that the Warrants  must be exercised  within  forty-five
         (45) days at which time any Warrants not exercised  shall be subject to
         cancellation by the Corporation.  Any  Warrantholders  who elect not to
         exercise their

         shall  surrender   their  Warrant   Certificates  to  the  Trustee  for
         cancellation.  Notwithstanding  that  a  Warrantholder  elects  not  to
         exercise his Warrants and fails to surrender his Warrant Certificate to
         the Trustee for cancellation,  the Warrants represented by such Warrant
         Certificate  shall  be  void  and  of no  value  at the  expiry  of the
         aforementioned forty-five (45) day notice period.

(c)      No  fractional  Warrants  shall be issued  or  otherwise  provided  for
         hereunder.

(d)      The  number of Common  Shares  which may be  acquired  pursuant  to the

         events and in the manner specified in Article 4.

2.3               Warrantholder not a Shareholder

                  Nothing in this  Indenture  or in the  holding of a Warrant or
Warrant  Certificate or otherwise,  shall, in itself,  confer or be construed as
conferring  upon  a  Warrantholder  any  right  of  interest   whatsoever  as  a
Shareholder or as any other shareholder of the Corporation,  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  Corporation,  or the right to
receive dividends and other distributions.

2.4                Warrants to Rank Pari Passu

                  All Warrants shall rank pari passu, whatever may be the actual
date of issue thereof.

2.5               Signing of Warrant Certificates

                  The Warrant  Certificates  shall be signed by any one director
or officer of the Corporation. The signatures of such director or officer may be
mechanically  reproduced  in  facsimile  and Warrant  Certificates  bearing such
facsimile  signatures  shall be binding upon the Corporation as if they had been
manually  signed by such  director or officer.  Notwithstanding  that any person
whose  manual or facsimile  signature  appears on any Warrant  Certificate  as a
director  or  officer  may no longer  hold  office  at the date of such  Warrant
Certificate or at the date of  certification  or delivery  thereof,  any Warrant
Certificate  signed as  aforesaid  shall,  subject to Section  2.6, be valid and
binding upon the  Corporation  and the holder  thereof  shall be entitled to the
benefits of this Indenture.

2.6               Certification by the Trustee

(a)      No Warrant  Certificate  shall be issued or, if issued,  shall 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 such  certification  by the Trustee upon any
         Warrant  Certificate  shall  be  conclusive  evidence  as  against  the
         Corporation  that the Warrant  Certificate  so certified  has been duly
         issued  hereunder  and that the  holder  is  entitled  to the  benefits
         hereof.

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

2.7               Issue in Substitution for Warrant Certificates Lost, etc.

(a)      In case any of the Warrant  Certificates  shall become  mutilated or be
         lost, destroyed or stolen, the Corporation,  subject to applicable law,
         shall issue and thereupon the Trustee shall certify and deliver,  a new
         Warrant Certificate of like tenor as the one mutilated, lost, destroyed
         or stolen in exchange for and in place of and upon cancellation of such
         mutilated  Warrant  Certificate,  or in lieu of and in substitution for
         such lost, destroyed or stolen Warrant Certificate, and the substituted
         Warrant  Certificate shall be in a form approved by the Trustee and the
         Warrants evidenced thereby shall be entitled to the benefits hereof and
         shall rank equally in accordance with its terms with all other Warrants
         issued or to be issued hereunder.

(b)      The  applicant for the issue of a new Warrant  Certificate  pursuant to
         this  Section 2.7 shall bear the cost of the issue  thereof and in case
         of loss,  destruction or theft shall,  as a condition  precedent to the
         issue  thereof,  furnish to the  Corporation  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  shall  be
         satisfactory  to the  Corporation  and to the  Trustee  in  their  sole
         discretion,  and such  applicant  may also be  required  to  furnish an
         indemnity  or  security  in  amount  and  form   satisfactory   to  the
         Corporation  and the  Trustee  in their  discretion  and  shall pay the
         reasonable  charges of the  Corporation  and the Trustee in  connection
         therewith.

2.8               Exchange of Warrant Certificates

(a)      Warrant  Certificates  representing  any number of Warrants  may,  upon

         representing the same aggregate number of Warrants as represented under
         the Warrant Certificate or Warrant Certificates so exchanged.

         any other place that is designated by the Corporation with the approval
         of the Trustee. Any Warrant

         Certificate tendered for exchange shall be cancelled and surrendered by
         the Warrant Agency to the Trustee.

2.9               Charges for Exchange

                  Except as otherwise  herein  provided,  the Warrant Agency may
charge to the  holder  requesting  an  exchange  a  reasonable  sum for each new
Warrant Certificate issued in exchange for Warrant  Certificate(s),  and payment
of such charges and  reimbursement of the Trustee or the Corporation for any and
all stamp taxes or  governmental  or other charges  required to be paid shall be

the Trustee  only upon  surrendering  to the  Trustee  the Warrant  Certificates
representing the Warrants to be transferred and upon compliance with:

               (i)         the conditions herein;

               (ii)        such  reasonable  requirements  as  the  Trustee  may

         the Warrantholder and shall specify:

                (i)        the number of Common  Shares which the holder  wishes
                           to  acquire  (being  not more  than  those  which the
                           holder is entitled to acquire pursuant to the Warrant
                           Certificate(s) surrendered);

         Shares  unless  or until  such  Warrantholder  shall  have  paid to the
         Corporation,  or the Warrant Agency on behalf of the  Corporation,  the
         amount of such tax or shall have established to the satisfaction of the
         Corporation that such tax has been paid or that no tax is due.

(c)      In connection with the exchange of Warrant Certificates and exercise of
         Warrants and compliance with such other terms and conditions  hereof as
         may be required, the Corporation has appointed the principal offices of
         the Trustee in Calgary as the agency at which Warrant  Certificates may
         be  surrendered  for exchange or at which Warrants may be exercised and
         the Trustee has accepted such  appointment.  The Corporation shall give
         notice to the Trustee of any change of the Warrant Agency.

3.2               Effect of Exercise of Warrants

(a)      Upon  compliance  by the  holder of any  Warrant  Certificate  with the
         provisions  of Section  3.1,  and  subject to Section  3.3,  the Common
         Shares  subscribed  for shall be deemed  to have  been  issued  and the
         person or persons to whom such Common  Shares are to be issued shall be
         deemed to have  become the  holder or holders of record of such  Common
         Shares on the  Exercise  Date  unless  the  transfer  registers  of the
         Corporation  shall be closed on such  date,  in which  case the  Common
         Shares  subscribed  for shall be deemed  to have been  issued  and such
         person or persons deemed to have become the holder or holders of record
         of such Common Shares, on the date on which such transfer registers are
         reopened.

(b)      Within five (5) Business  Days after the Exercise  Date of a Warrant as
         set forth above, the Corporation shall cause to be mailed to the person
         or persons in whose name or names the Common Shares so  subscribed  for
         have been  issued,  as specified  in the  subscription,  at the address
         specified   in  such   subscription   or,  if  so   specified  in  such
         subscription,  cause to be  delivered  to such person or persons at the
         Warrant Agency where the Warrant  Certificate was surrendered,  a share
         certificate or certificates for the appropriate number of Common Shares
         subscribed for.

3.3               Partial Exercise of Warrants; Fractions

(a)      The holder of any Warrants  may acquire a number of Common  Shares less
         than the number which the holder is entitled to acquire pursuant to the
         surrendered  Warrant  Certificate(s)  provided  that, in no event shall
         fractional  Common Shares be issued with regard to Warrants  exercised.
         In the event of any  acquisition of a number of Common Shares less than
         the number  which the holder is entitled to acquire,  the holder of the
         Warrants  upon  exercise  thereof  shall,  in addition,  be entitled to
         receive,  without  charge  therefor,  a new Warrant  Certificate(s)  in
         respect  of the  balance  of the Common  Shares  which such  holder was
         entitled to acquire pursuant to the surrendered Warrant  Certificate(s)
         and which were not then acquired.

(b)      Notwithstanding  anything  herein  contained  including any  adjustment
         provided for in Article 4, the Corporation shall not be required,  upon
         the exercise of any Warrants, to issue fractions of Common Shares or to
         distribute  certificates  which evidence  fractional  Common Shares. In
         lieu of  fractional  Common  Shares,  there shall be paid to the holder
         upon  surrender  of Warrant  Certificate(s)  for  exercise  of Warrants
         pursuant  to  Section  3.1,  within  ten (10)  Business  Days after the
         Exercise  Date,  an amount in lawful  money of Canada equal to the then
         current market value of such fractional  interest computed on the basis
         of the closing price of the Common Shares on The Alberta Stock Exchange
         (or if the  Common  Shares  are not then  listed  thereon on such other
         exchange  on which  such  shares  are  listed  or, if not listed on any
         exchange,  in the  over-the-counter  market, as designated by action of
         the  directors) for the Trading Day  immediately  prior to the Exercise
         Date or where there is no sale on the applicable  exchange or market on

         who is at the time a "US Person" as defined in  Regulation  S under the
         United States Securities Act of 1933, the certificates representing the

         Corporation.

(b)      The Trustee shall record the  particulars of Warrants  exercised  which
         shall include the names and addresses of the persons who become holders

4.1               Adjustment of Number of Common Shares

                  The  acquisition  rights as they relate to Common  Shares,  in
effect at any date attaching to the Warrants,  and the Exercise Price in respect
thereof, shall be subject to adjustment from time to time as follows:

(a)      if and whenever at any time after the  Effective  Date and prior to the
         Time of Expiry, the Corporation shall:

               (i)         subdivide,  redivide  or  change  outstanding  Common
                           Shares into a greater number of shares;

               (ii)        reduce, combine or consolidate the outstanding Common
                           Shares into a smaller number of shares, or

              (iii)        issue  Common   Shares  to  the  holders  of  all  or
                           substantially all of the outstanding Common Shares by
                           way of a stock  dividend  (other  than  the  issue of
                           Common Shares to holders of Common Shares pursuant to
                           their exercise of options to receive dividends in the
                           form of Common  Shares in lieu of  Dividends  Paid in
                           the Ordinary Course on the Common Shares),

         the Exercise Price in effect on the effective date of such subdivision,
         redivision,  reduction,  combination or  consolidation or on the record
         date for such issue of Common Shares by way of a stock dividend, as the
         case may be,  shall in the case of the  events  referred  to in (i) and
         (iii) above be decreased  in  proportion  to the number of  outstanding
         Common Shares resulting from such subdivision,  redivision or dividend,
         or shall,  in the case of the  events  referred  to in (ii)  above,  be
         increased in  proportion  to the number of  outstanding  Common  Shares
         resulting  from such  reduction,  combination  or  consolidation.  Such
         adjustment shall be made successively whenever any event referred to in
         this subsection  4.1(a) shall occur; any such issue of Common Shares by
         way of a stock dividend shall be deemed to have been made on the record
         date for the stock dividend for the purpose of  calculating  the number
         of outstanding Common Shares under subsections 4.1(b) and 4.1(c).  Upon
         any adjustment of the Exercise Price pursuant to subsection 4.1(a), the
         number of Common  Shares  subject to the right of  purchase  under each
         Warrant shall be  contemporaneously  adjusted by multiplying the number
         of Common Shares which  theretofore  may have been purchased under such
         Warrant by a fraction of which the  numerator  shall be the  respective
         Exercise Price in effect  immediately  prior to such adjustment and the
         denominator shall be the respective  Exercise Price resulting from such
         adjustment;

(b)      if and whenever at any time after the  Effective  Date and prior to the
         Time of  Expiry,  the  Corporation  shall  fix a  record  date  for the
         issuance of rights or warrants to all or substantially  all the holders
         of its outstanding Common Shares entitling them, for a

         period  expiring  not more than 45 days  after  such  record  date,  to
         subscribe for or purchase  Common Shares (or securities  convertible or
         exchangeable  into  Common  Shares)  at a price per share (or  having a
         conversion  or  exchange  price per share) less than 95% of the Current
         Market Price on such record date,  the Exercise Price shall be adjusted
         immediately  after such  record  date so that it shall equal the amount
         determined by  multiplying  the Exercise Price in effect on such record
         date by a fraction of which the numerator  shall be the total number of
         Common Shares  outstanding  on such record date plus a number of Common
         Shares equal to the number  arrived at by dividing the aggregate  price
         of  the  total  number  of  additional   Common   Shares   offered  for
         subscription or purchase (or the aggregate conversion or exchange price
         of the  convertible  or  exchangeable  securities  so  offered) by such
         Current Market Price,  and of which the denominator  shall be the total
         number of Common Shares  outstanding on such record date plus the total
         number of additional Common Shares offered for subscription or purchase
         or into which the convertible or exchangeable securities so offered are
         convertible or exchangeable; any Common Shares owned by or held for the
         account of the Corporation or any Subsidiary  shall be deemed not to be
         outstanding  for the purpose of any such  computation;  such adjustment
         shall be made successively whenever such a record date is fixed; to the
         extent that any such rights or warrants are not exercised  prior to the
         expiration  thereof,  the  Exercise  Price shall be  readjusted  to the
         Exercise  Price  which  would then be in effect if such record date had
         not been fixed or to the Exercise  Price which would be in effect based
         upon  the  number  of  Common  Shares  (or  securities  convertible  or
         exchangeable  into Common Shares)  actually issued upon the exercise of
         such rights or warrants, as the case may be;

(c)      if and whenever at any time after the  Effective  Date and prior to the
         Time of Expiry,  the Corporation shall fix a record date for the making
         of a  distribution  to all or  substantially  all  the  holders  of its
         outstanding  Common  Shares of (i) shares of any class,  whether of the
         Corporation  or any other  corporation  (other than  Common  Shares and
         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), (ii) rights,  options or warrants (excluding those referred to
         in subsection  4.1(b) and rights,  options or warrants to subscribe for
         or purchase  Common  Shares (or other  securities  convertible  into or
         exchangeable  for Common Shares) for a period expiring not more than 45
         days  after  such  record  date at a  price  per  share  (or  having  a
         conversion  or  exercise  price  per  share)  not less  than 95% of the
         Current  Market  Price on such record  date),  (iii)  evidences  of its
         indebtedness or (iv) assets  (excluding  Dividends Paid in the Ordinary
         Course)  then,  in each case,  the  Exercise  Price  shall be  adjusted
         immediately  after such  record  date so that it shall  equal the price
         determined by  multiplying  the Exercise Price in effect on such record
         date by a fraction, of which the numerator shall be the total number of
         Common Shares outstanding on such record date multiplied by the Current
         Market  Price on such  record  date,  less the fair  market  value  (as
         determined by the directors,  which  determination shall be conclusive)
         of such shares, rights, options, warrants, evidences of indebtedness or
         assets so

         distributed,  and of which the denominator shall be the total number of
         Common  Shares  outstanding  on such  record  date  multiplied  by such
         Current  Market  Price;  and  Common  Shares  owned  by or held for the
         account of the Corporation or any Subsidiary  shall be deemed not to be
         outstanding  for the purpose of any such  computation;  such adjustment
         shall be made successively whenever such a record date is fixed; to the
         extent that such  distribution is not so made, the Exercise Price shall
         be  readjusted  to the Exercise  Price which would then be in effect if
         such  record  date had not been fixed or to the  Exercise  Price  which
         would then be in effect  based upon such  shares or rights,  options or
         warrants or evidences of indebtedness  or assets actually  distributed,
         as the case may be; in clause (iv) of this  subsection  4.1(c) the term
         "Dividends Paid in the Ordinary  Course" shall include the value of any
         securities  or other  property  or assets  distributed  in lieu of cash
         Dividends Paid in the Ordinary Course at the option of shareholders;

(d)      if and when at any time from the  Effective  Date and prior to the Time
         of  Expiry,  there is a  reclassification  of the  Common  Shares  or a
         capital reorganization of the Corporation or as described in subsection
         4.1(a) or a consolidation,  amalgamation,  arrangement or merger of the
         Corporation with or into any other body corporate,  trust,  partnership
         or other entity,  or a sale or conveyance of the property and assets of
         the Corporation as an entirety or  substantially  as an entirety to any
         other  body  corporate,   trust,   partnership  or  other  entity,  any
         Warrantholder  who has not exercised its right of acquisition  prior to
         the   effective   date   of  such   reclassification,   reorganization,
         consolidation,  amalgamation,  arrangement, merger, sale or conveyance,
         upon the  exercise  of such  right  thereafter,  shall be  entitled  to
         receive and shall  accept,  in lieu of the number of Common Shares then
         sought to be acquired  by it, the number of shares or other  securities
         or  property  of the  Corporation  or of  the  body  corporate,  trust,
         partnership or other entity  resulting from such merger,  amalgamation,
         arrangement or  consolidation,  or to which such sale or conveyance may
         be made,  as the case may be, that such  Warrantholder  would have been
         entitled to receive on such reclassification,  capital  reorganization,
         consolidation,  amalgamation,  arrangement, merger, sale or conveyance,
         if, on the record date or the effective  date thereof,  as the case may
         be, the  Warrantholder  had been the registered holder of the number of
         Common Shares sought to be acquired by it. If determined appropriate by
         the  Trustee to give effect to or to evidence  the  provisions  of this
         subsection 4.1(d), the Corporation,  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  reclassification,
         reorganization,  consolidation, amalgamation, arrangement, merger, sale
         or  conveyance,  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  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 Corporation and the Trustee pursuant to the provisions
         of this subsection 4.1(d) shall be a supplemental

         indenture  entered into  pursuant to the  provisions  of Article 8. Any
         indenture  entered into between the  Corporation,  any successor to the
         Corporation 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  Section  4.1 and  which  shall  apply to  successive
         reclassification,    reorganizations,    amalgamation,    arrangements,
         consolidations, mergers, sales or conveyances;

(e)      in any case in which this Section 4.1 shall  require that an adjustment
         shall  become  effective  immediately  after a record date for an event
         referred to herein,  the Corporation may defer, until the occurrence of
         such event,  issuing to the holder of any Warrant  exercised after such
         record  date and before  the  occurrence  of such event the  additional
         Common Shares  issuable upon such exercise by reason of the  adjustment
         required by such event;  provided,  however, that the Corporation shall
         deliver  to such  holder  an  appropriate  instrument  evidencing  such
         holder's  right to  receive  such  additional  Common  Shares  upon the
         occurrence  of the event  requiring  such  adjustment  and the right to
         receive  any  distributions  made  on  such  additional  Common  Shares
         declared  in favour of holders of record of Common  Shares on and after
         the relevant  date of exercise or such later date as such holder would,
         but for the  provisions  of this  subsection  4.1(e),  have  become the
         holder  of  record  of  such  additional   Common  Shares  pursuant  to
         subsection 4.1(b);

(f)      in any case in which  subsections  4.1(b)  or  4.1(c)  require  that an
         adjustment be made to the Exercise Price,  no such adjustment  shall be
         made if, subject to the prior  approval of The Alberta Stock  Exchange,
         the holders of the outstanding  Warrants receive the rights or warrants
         referred  to in  subsection  4.1(b)  or the  shares,  rights,  options,
         warrants, evidences of indebtedness or assets referred to in subsection
         4.1(c),  as the case may be, in such kind and number as they would have
         received if they had been  holders of Common  Shares on the  applicable
         record date or effective  date,  as the case may be, by virtue of their
         outstanding  Warrant  having then been  exercised into Common Shares at
         the Exercise Price in effect on the applicable record date or effective
         date, as the case may be;

(g)      the adjustments  provided for in this Section 4.1 are  cumulative,  and
         shall,  in the case of adjustments to the Exercise Price be computed to
         the  nearest  whole cent and shall  apply to  successive  subdivisions,
         redivisions, reductions, combinations,  consolidations,  distributions,
         issues or other events resulting in any adjustment under the provisions
         of this Section 4.1 provided that,  notwithstanding any other provision
         of this Section,  no adjustment of the Exercise Price shall be required
         unless  such  adjustment  would  require an  increase or decrease of at
         least 1% in the Exercise Price then in effect; provided,  however, that
         any  adjustments  which by reason  of this  subsection  4.1(g)  are not
         required to be made shall be carried  forward and taken into account in
         any subsequent adjustment; and

(h)      after any  adjustment  pursuant to this  Section  4.1, the term "Common
         Shares"  where  used in this  Indenture  shall be  interpreted  to mean
         securities  of  any  class  or  classes  which,  as a  result  of  such
         adjustment and all prior adjustments  pursuant to this Section 4.1, the
         Warrantholder  is entitled to receive  upon the exercise of his Warrant
         and the number of Common Shares indicated by any exercise made pursuant
         to a Warrant shall be  interpreted  to mean the number of Common Shares
         or other property or securities a Warrantholder is entitled to receive,
         as a result of such  adjustment and all prior  adjustments  pursuant to
         this Section 4.1, upon the full exercise of a Warrant.

4.2               Entitlement to Common Shares on Exercise of  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 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.

4.3               No Adjustment for Stock Options or Warrants

                  Anything in this Article 4 to the contrary notwithstanding, no
adjustment  shall be made in the acquisition  rights attached to the Warrants if
the issue of Common Shares is being made pursuant to this  Indenture or pursuant
to any stock option,  stock purchase or employee RRSP plan in force from time to
time for officers or employees  of the  Corporation,  or pursuant to any warrant
outstanding immediately prior to the Effective Date.

4.4               Determination by Corporation's Auditors

                  In the  event of any  question  arising  with  respect  to the
adjustments  provided for in this Article 4 such question shall be  conclusively
determined by the Corporation's  Auditors who shall have access to all necessary
records of the  Corporation,  and such  determination  shall be binding upon the
Corporation,  the Trustee,  all  Warrantholders and all other persons interested
therein.

4.5               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  Warrants,  including  the number of Common  Shares which are to be received
upon the exercise thereof, the Corporation shall take any corporate action which
may, in the opinion of counsel,  be necessary in order that the  Corporation 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 holders of such
Warrants are entitled to receive on the full exercise thereof in accordance with
the provisions hereof.

4.6               Certificate of Adjustment

                  The Corporation  shall from time to time immediately after the
occurrence of any event which requires an adjustment or readjustment as provided
in Article 4, deliver a certificate of the Corporation to the Trustee specifying
the  nature of the event  requiring  the same and the  amount of the  adjustment
necessitated  thereby  and  setting  forth in  reasonable  detail  the method of
calculation  and  the  facts  upon  which  such  calculation  is  based,   which
certificate  shall be supported by a certificate of the  Corporation's  auditors
verifying such calculation.

4.7               Notice of  Matters

                  The  Corporation  covenants  with the Trustee that, so long as
any Warrant remains  outstanding,  it will give notice to the Trustee and to the
Warrantholders of its intention to fix the record date for any event referred to
in  subsection  4.1(a),  (b) or (c)  (other  than the  subdivision,  redivision,
reduction,  combination  or  consolidation  of its Common Shares) which may give
rise to an  adjustment  of the Exercise  Price.  Such notice  shall  specify the
particulars of such event and the record date for such event,  provided that the
Corporation  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 case not less than  fourteen
(14) days prior to such applicable record date.

4.8               No Action after Notice

                  The  Corporation  covenants  with the Trustee that it will not
close its transfer books or take any other corporate  action which might deprive
the holder of a Warrant of the  opportunity to exercise its right of acquisition
pursuant thereto during the period of fourteen (14) days after the giving of the
certificate or notices set forth in Section 4.6 and 4.7.

4.9               Protection of Trustee

                  Except as provided in Section 9.2, the Trustee:

(a)      shall  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 Section  4.1, or with  respect to the
         nature or extent of any such  adjustment  when made, or with respect to
         the method employed in making the same;

(b)      shall not be accountable  with respect to the validity or value (or the
         kind  or  amount)  of any  Common  Shares  or 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 Warrant;

(c)      shall not be responsible  for any failure of the  Corporation to issue,
         transfer or deliver Common Shares or certificates for the same upon the
         surrender of any Warrants for the

         purpose of the  exercise  of such  rights or to comply  with any of the
         covenants contained in this Article; and

(d)      shall not incur any liability or responsibility whatsoever or be in any
         way responsible  for the  consequences of any breach on the part of the
         Corporation  of any of the  representations,  warranties  or  covenants
         herein  contained  or of any  acts of the  agents  or  servants  of the
         Corporation.

4.10              Other Adjustments

                  In case the  Corporation  after the date hereof shall take any
action  affecting the Common Shares  described in Article 4 which in the opinion
of the  directors  or the Trustee  would have a material  adverse  effect on the
rights of the  Warrantholders,  the Exercise Price and/or the number and/or kind
of Common Shares  purchaseable  upon  exercise,  there shall be an adjustment in
such manner, if any, and at such time, as the directors may determine subject to
the prior consent of The Alberta Stock Exchange. Failure of the taking of action
by the directors so as to provide for an adjustment  prior to the effective date
of any action by the Corporation affecting the Common Shares shall be conclusive
evidence  that the  directors  have  determined  that it is equitable to make no
adjustment in the circumstances.


                                    ARTICLE 5
                     RIGHTS OF THE CORPORATION AND COVENANTS


5.1               Optional Purchases by the Corporation

                  The  Corporation  may from time to time  purchase  by  private
contract or otherwise  any of the Warrants.  Any such purchase  shall be made at
the  lowest  price or prices at which,  in the  opinion of the  directors,  such
Warrants are then obtainable, plus reasonable costs of purchase, and may be made
in such manner, from such persons and on such other terms as the Corporation, in
its sole discretion,  may determine.  Any Warrant Certificates  representing the
Warrants  purchased pursuant to this Section 5.1 shall forthwith be delivered to
and  cancelled  by the  Trustee.  No  Warrants  shall be issued  in  replacement
thereof.

5.2               General Covenants

                  The Corporation covenants with the Trustee that so long as any
Warrants remain outstanding:

(a)      it will reserve and keep available a sufficient number of Common Shares
         for the  purpose of enabling  it to satisfy  its  obligations  to issue
         Common Shares upon the exercise of the Warrants;

<PAGE>


                                                      - 22 -


(b)      it will cause the Common Shares and the  certificates  representing the
         Common  Shares from time to time  acquired  pursuant to the exercise of
         the  Warrants to be duly issued and  delivered in  accordance  with the
         Warrant Certificates and the terms hereof;

(c)      all Common  Shares which shall be issued upon  exercise of the right to
         acquire  provided for herein and in the Warrant  Certificates  shall be
         fully paid and non-assessable;

(d)      it will use its  reasonable  best  efforts to  maintain  its  corporate
         existence;

(e)      it will use its  reasonable  best  efforts  to ensure  that all  Common
         Shares of the  Corporation  outstanding  or issuable  from time to time
         continue  to be or are listed and  posted  for  trading on The  Alberta
         Stock Exchange;

(f)      it will make all requisite filings under applicable Canadian securities
         legislation  including those necessary to remain a reporting issuer not
         in default in Alberta and those necessary to report the exercise of the
         right to acquire Common Shares pursuant to Warrants; and

(g)      generally, it will well and truly perform and carry out all of the acts
         or things to be done by it as provided in this Indenture.

5.3               Trustee's Remuneration and Expenses

                  The Corporation covenants that it will pay to the Trustee from
time to time reasonable  remuneration for its services hereunder and will pay or
reimburse   the  Trustee   upon  its  request  for  all   reasonable   expenses,
disbursements and advances incurred or made by the Trustee in the administration
or execution of the trusts hereby created (including the reasonable compensation
and the  disbursements  of its counsel and all other advisers and assistants not
regularly in its employ) both before any default  hereunder and thereafter until
all duties of the Trustee hereunder shall be finally and fully performed, except
any such expense, disbursement or advance as may arise out of or result from the
Trustee's negligence, willful misconduct or bad faith.

5.4               Securities Qualification Requirements

(a)      If,  in the  opinion  of  counsel,  any  instrument  (not  including  a
         prospectus) is required to be filed with, or any permission is required
         to be obtained from any  governmental  authority in Canada or any other
         step is required  under any federal or provincial  law of Canada before
         any Common Shares which a Warrantholder is entitled to acquire pursuant
         to the  exercise of any Warrant may properly and legally be issued upon
         due exercise thereof and thereafter  traded,  without further formality
         or  restriction,  the  Corporation  covenants  that it will  take  such
         required action.

(b)      The  Corporation or, if required by the  Corporation,  the Trustee will
         give notice of the issue of Common  Shares  pursuant to the exercise of
         Warrants,  in  such  detail  as may be  required,  to  each  securities
         commission  or similar  regulatory  authority in each  jurisdiction  in
         Canada  in which  there is  legislation  or  regulation  permitting  or
         requiring  the  giving of any such  notice in order  that such issue of
         Common Shares and the  subsequent  disposition  of the Common Shares so
         issued will not be subject to the prospectus qualification requirements
         of such legislation or regulation.

5.5               Performance of Covenants by Trustee

                  If the Corporation  shall fail to perform any of its covenants
contained in this Warrant  Indenture,  the Trustee may notify the Warrantholders
of such failure on the part of the  Corporation or may itself perform any of the
covenants capable of being performed by it but, subject to Section 9.2, shall be
under no obligation to perform said covenants or to notify the Warrantholders of
such performance by it. All sums expended or advanced by the Trustee in so doing
shall be repayable as provided in Section 5.3. No such performance,  expenditure
or advance by the Trustee shall relieve the Corporation of any default hereunder
or of its continuing obligations under the covenants herein contained.


                                    ARTICLE 6
                                   ENFORCEMENT

6.1               Suits by Warrantholders

                  All or any of the rights  conferred upon any  Warrantholder by
any of the terms of the Warrant  Certificates  or of the Indenture,  or of both,
may be enforced by the  Warrantholder  by  appropriate  proceedings  but without
prejudice to the right which is hereby  conferred upon the Trustee to proceed in
its own name to enforce each and all of the provisions  herein contained for the
benefit of the Warrantholders.

6.2               Suits by Corporation

                  The  Corporation  shall have the right to enforce full payment
of  the  Exercise  Price  of all  Common  Shares  issued  by  the  Trustee  to a
Warrantholder  hereunder,  and shall be entitled to demand such payment from the
Warrantholder  or  alternatively  to  instruct  the  Trustee to cancel the share
certificates and amend the securities register accordingly.

6.3               Immunity of Shareholders, etc.

                  The Trustee and, by the acceptance of the Warrant Certificates
and  as  part  of  the  consideration  for  the  issue  of  the  Warrants,   the
Warrantholders hereby waive and release any right, cause of action or remedy now
or hereafter existing in any jurisdiction against any

incorporator  or any past,  present or future  shareholder,  director,  officer,
employee or agent of the  Corporation  or of any  successor  Corporation  on any
covenant, agreement,  representation or warranty by the Corporation herein or in
the Warrant Certificates contained.

6.4               Limitation of Liability

                  The obligations hereunder are not personally binding upon, nor
shall  resort  hereunder  be had to, the  private  property  of any of the past,
present  or  future  directors  or  shareholders  of the  Corporation  or of any
successor Corporation or any of the past, present or future officers,  employees
or agents of the Corporation or any successor Corporation, but only the property
of the  Corporation  or any  successor  Corporation  shall be  bound in  respect
hereof.

6.5               Waiver of Default

                  Upon the happening of any default hereunder:

(a)      the holders of not less than 51% of the Warrants then outstanding shall
         have power (in  addition  to the powers  exercisable  by  extraordinary
         resolution  as provided in Section 7.10) by  requisition  in writing to
         instruct  the  Trustee to waive any default  hereunder  and the Trustee
         shall  thereupon  waive the default upon such terms and  conditions  as
         shall be prescribed in such requisition; or

(b)      the Trustee shall have power to waive any default  hereunder  upon such
         terms and  conditions  as the Trustee on advice of its counsel may deem
         advisable, if, in the Trustee's opinion, the same shall have been cured
         or adequate provision made therefor;

provided  that no delay or omission of the Trustee or of the  Warrantholders  to
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 7
                           MEETINGS OF WARRANTHOLDERS

7.1               Right to Convene Meetings

                  The Trustee  may at any time and from time to time,  and shall
on  receipt  of a written  request of the  Corporation  or of a  Warrantholders'
Request and upon being indemnified and funded to its reasonable  satisfaction by
the Corporation or by the Warrantholders  signing such  Warrantholders'  Request
against the cost which may be incurred in connection with the

calling and holding of such meeting, convene a meeting of the Warrantholders. In
the event of the Trustee  failing to so convene a meeting  within seven (7) days
after receipt of such written request of the Corporation or such Warrantholders'
Request  and   indemnity   given  as   aforesaid,   the   Corporation   or  such
Warrantholders, as the case may be, may convene such meeting. Every such meeting
shall be held in the City of Calgary or at such other  place as may be  approved
or determined by the Trustee.

7.2               Notice

                  At  least  ten (10)  days'  prior  notice  of any  meeting  of
Warrantholders  shall be given to the  Warrantholders in the manner provided for
in Section  10.2 and a copy of such notice  shall be sent by mail to the Trustee
(unless  the  meeting has been  called by the  Trustee)  and to the  Corporation
(unless the meeting has been called by the Corporation). Such notice shall state
the time when and the place where the meeting is to be held, shall 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 shall not be necessary  for any such
notice  to set out the  terms of any  resolution  to be  proposed  or any of the
provisions of this Article 7.

7.3               Chairman

                  An individual (who need not be a Warrantholder)  designated in
writing by the Trustee  shall be chairman of the meeting and if no individual is
so designated,  or if the individual so designated is not present within fifteen
(15)  minutes  from  the  time  fixed  for  the  holding  of  the  meeting,  the
Warrantholders  present  in  person or by proxy  shall  choose  some  individual
present to be chairman.

7.4               Quorum

                  Subject to the  provisions  of Section 7.11, at any meeting of
the Warrantholders a quorum shall consist of Warrantholders present in person or
by proxy and entitled to purchase at least 25% of the aggregate number of Common
Shares which could be acquired  pursuant to all the then  outstanding  Warrants,
provided  that at least two  persons  entitled to vote  thereat  are  personally
present.  If a quorum of the  Warrantholders  shall not be present within thirty
(30)  minutes  from the time fixed for  holding any  meeting,  the  meeting,  if
summoned  by  the  Warrantholders  or on a  Warrantholders'  Request,  shall  be
dissolved;  but in any other case the meeting shall be adjourned to the same day
in the next week (unless such day is not a Business  Day, in which case it shall
be adjourned to the next following  Business Day) at the same time and place and
no notice of the adjournment  need be given.  Any business may be brought before
or dealt with at an  adjourned  meeting  which might have been dealt with at the
original  meeting in  accordance  with the notice  calling the same. No business
shall  be  transacted  at  any  meeting  unless  a  quorum  be  present  at  the
commencement of business. At the adjourned meeting the Warrantholders present in
person or by proxy shall form a quorum and may transact the business

for which the meeting was originally convened, notwithstanding that they may not
be entitled  to acquire at least 25% of the  aggregate  number of Common  Shares
which may be acquired pursuant to all then outstanding Warrants.

7.5               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 any such
meeting,  and no notice of such adjournment need be given except such notice, if
any, as the meeting may prescribe.

7.6               Show of Hands

                  Every question  submitted to a meeting shall be decided in the
first  place by a majority  of the votes  given on a show of hands  except  that
votes on an extraordinary  resolution  shall be given in the manner  hereinafter
provided.  At any  such  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 shall be conclusive evidence of the fact.

7.7               Poll and Voting

                  On every extraordinary  resolution,  and on any other question
submitted  to a meeting  and after a vote by show of hands when  demanded by the
chairman  or by one or more of the  Warrantholders  acting in person or by proxy
and entitled to acquire in the aggregate at least 5% of the aggregate  number of
Common  Shares  which  could  be  acquired  pursuant  to all the  Warrants  then
outstanding,  a poll shall be taken in such manner as the chairman shall direct.
Questions other than those required to be determined by extraordinary resolution
shall be decided by a majority of the votes cast on the poll.

                  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,  shall have one vote.  On a poll,  each  Warrantholder
present in person or  represented  by a proxy duly  appointed by  instrument  in
writing  shall be  entitled  to one vote in respect of each whole  Common  Share
which he is entitled to acquire pursuant to the Warrant or Warrants then held or
represented  by it. A proxy need not be a  Warrantholder.  The  Chairman  of any
meeting  shall be  entitled,  both on a show of hands and on a poll,  to vote in
respect of the Warrants, if any, held or represented by him.

7.8               Regulations

                  The  Trustee,  or the  Corporation  with the  approval  of the
Trustee,  may from time to time make and from time to time vary such regulations
as it shall think fit for:

         at  such  place  and  time  as  the  Trustee,  the  Corporation  or the

7.11              Meaning of Extraordinary Resolution

(a)      The expression  "extraordinary  resolution" when used in this Indenture
         means,  subject as  hereinafter  provided in this  Section  7.11 and in
         Section 7.14, a resolution proposed at a meeting of Warrantholders duly
         convened for that purpose and held in accordance with the provisions of
         this  Article  7 at which  there  are  present  in  person  or by proxy
         Warrantholders entitled to acquire at least 25% of the aggregate number
         of  Common  Shares  which  may be  acquired  pursuant  to all the  then
         outstanding   Warrants   and  passed  by  the   affirmative   votes  of
         Warrantholders  entitled  to  acquire  not  less  than  66  2/3% of the
         aggregate number of Common Shares which may be acquired pursuant to all
         the then  outstanding  Warrants  represented at the meeting and vote on
         the poll upon such resolution.

(b)      If,  at the  meeting  at which  an  extraordinary  resolution  is to be
         considered,  Warrantholders  entitled  to  acquire  at least 25% of the
         aggregate number of Common Shares which may be acquired pursuant to all
         the then  outstanding  Warrants  are not  present in person or by proxy
         within  thirty (30) minutes  after the time  appointed for the meeting,
         then the meeting,  if convened by Warrantholders or on  Warrantholders'
         Request, shall be dissolved;  but in any other shall stand adjourned to
         such day,  being not less than  fifteen  nor more than  sixty (60) days
         later,  and to such place and time as  appointed by the  chairman.  Not
         less than ten (10) days'  prior  notice  shall be given of the time and
         place of such adjourned  meeting in the manner  provided for in Section
         10.2.  Such  notice  shall  state  that at the  adjourned  meeting  the
         Warrantholders present in person or by proxy shall form a quorum but it
         shall 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 shall form a
         quorum  and may  transact  the  business  for  which  the  meeting  was
         originally convened and a resolution proposed at such adjourned meeting
         and passed by the  requisite  vote as  provided in  subsection  7.11(a)
         shall  be an  extraordinary  resolution  within  the  meaning  of  this
         Indenture  notwithstanding  that Warrantholders  entitled to acquire at
         least  25% of the  aggregate  number  of  Common  Shares  which  may be
         acquired pursuant to all the then outstanding  Warrants are not present
         in person or by proxy at such adjourned meeting.

(c)      Votes on an  extraordinary  resolution  shall always be given on a poll
         and no  demand  for a poll  on an  extraordinary  resolution  shall  be
         necessary.

7.12              Powers Cumulative

                  Any one or more of the powers or any combination of the powers
in  this  Indenture   stated  to  be  exercisable  by  the   Warrantholders   by
extraordinary resolution or otherwise may be exercised from time to time and the
exercise  of any one or more of such  powers or any  combination  of powers from
time to time shall not be deemed to exhaust the right of the

to time for that purpose by the Trustee at the expense of the  Corporation,  and
any such minutes as aforesaid, if signed by the chairman or the secretary of the
meeting at which such  resolutions were passed or proceedings had shall be prima
facie evidence of the matters  therein stated and, until the contrary if proved,
every such meeting in respect of the  proceedings  of which  minutes  shall have
been  made  shall be  deemed  to have  been  duly  convened  and  held,  and all
resolutions  passed  thereat or  proceedings  taken shall be deemed to have been
duly passed and taken.

7.14              Instruments in Writing

                  All  actions  which  may be taken and all  powers  that may be

may also be taken and exercised by  Warrantholders  entitled to acquire at least
66 2/3% of the aggregate number of Common Shares which may be acquired  pursuant
to all the then  outstanding  Warrants by an instrument in writing signed in one
or more  counterparts  by such  Warrantholders  in  person or by  attorney  duly
appointed in writing, and the expression "extraordinary resolution" when used in
this Indenture shall include an instrument so signed.

7.15              Binding Effect of Resolution

                  Every resolution and every extraordinary  resolution passed in
accordance with the provisions of this Article 7 at a meeting of  Warrantholders
shall be binding upon all the Warrantholders,  whether present at or absent from
such  meeting,  and every  instrument  in writing  signed by  Warrantholders  in
accordance  with  Section  7.14  shall be binding  upon all the  Warrantholders,

Trustee  (subject to the provisions  for indemnity  herein  contained)  shall be
bound to give effect  accordingly  to every such  resolution  and  instrument in
writing.

7.16              Holdings by Corporation Disregarded

                  In  determining   whether   Warrantholders   holding   Warrant
Certificates evidencing the entitlement to acquire the required number of Common
Shares are present at a meeting of Warrantholders for the purpose of determining
a quorum or have  concurred in any consent,  waiver,  extraordinary  resolution,
Warrantholders'  Request or other action under this  Indenture,  Warrants  owned
legally or  beneficially by the Corporation or any Subsidiary of the Corporation
shall be disregarded in accordance with the provisions of Section 10.8.

8.1               Provision for Supplemental Indentures for Certain Purposes

                  From time to time the Corporation  (when  authorized by action
of the directors) and the Trustee may,  subject to the  provisions  hereof,  and
they shall, when so directed in accordance with the provisions  hereof,  execute
and deliver by their proper  officers,  indentures or  instruments  supplemental
hereto,  which thereafter shall form part hereof,  for any one or more or all of
the following purposes:

(a)      setting forth any  adjustments  resulting  from the  application of the
         provisions of Article 4;

(b)      adding  to  the  provisions   hereof  such  additional   covenants  and
         enforcement  provisions as, in the opinion of Counsel, are necessary or
         advisable  in the  premises,  provided  that  the  same  are not in the
         opinion  of  the  Trustee   prejudicial   to  the   interests   of  the
         Warrantholders;

(c)      giving  effect to any  extraordinary  resolution  passed as provided in
         Article 7;

         hereunder or for the purpose of obtaining a listing or quotation of the
         Warrants on any stock exchange,  provided that such provisions are not,
         in the opinion of the Trustee on advice of its counsel,  prejudicial to

         the Corporation from any of the obligations, conditions or restrictions
         herein contained, provided that such modification or relief shall be or
         become operative or effective only if, in the opinion of the Trustee on
         advice of its counsel, such modification or relief in no way prejudices
         any of the rights of the Warrantholders or of the Trustee, and provided
         further  that the Trustee may in its sole  discretion  decline to enter
         into any such  supplemental  indenture  which  in its  opinion  may not
         afford  adequate  protection  to the Trustee when the same shall become
         operative; and

the  successor  Corporation  resulting  from such  consolidation,  amalgamation,

supplemental  indenture  satisfactory  in form to the Trustee and  executed  and
delivered to the Trustee,  the due and punctual  performance  and  observance of

observed by the Corporation.


                                    ARTICLE 9
                             CONCERNING THE TRUSTEE

9.1               Trust Indenture Legislation

(a)      If and to the  extent  that any  provision  of this  Indenture  limits,
         qualifies  or  conflicts  with a mandatory  requirement  of  Applicable
         Legislation, such mandatory requirement shall prevail.

(b)      The  Corporation  and the Trustee agree that each will, at all times in
         relation  to this  Indenture  and any  action  to be  taken  hereunder,
         observe and comply with and be entitled to the  benefits of  Applicable
         Legislation.

9.2               Rights and Duties of Trustee

(a)      In the exercise of the rights and duties prescribed or conferred by the
         terms of this  Indenture,  the Trustee  shall  exercise  that degree of
         care,  diligence  and skill that a  reasonably  prudent  trustee  would
         exercise in comparable  circumstances.  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 willful
         misconduct or bad faith.

(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   hereunder   shall   be   conditional   upon  the
         Warrantholders  furnishing,  when  required  by notice by the  Trustee,
         sufficient  funds to  commence  or to  continue  such  act,  action  or
         proceeding and an indemnity  reasonably  satisfactory to the Trustee to
         protect and to 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  shall require the Trustee to expend or to risk its own
         funds or otherwise

(#44838/WARRANT INDENTURE - February 21, 1997)

         in the exercise of any of its rights or powers  unless  indemnified  as
         aforesaid.

(c)      The  Trustee  may,  before   commencing  or  at  any  time  during  the
         continuance  of  any  such  act,  action  or  proceeding,  require  the
         Warrantholders,  at whose  instance  it is acting to  deposit  with the
         Trustee the Warrants held by them, for which Warrants the Trustee shall
         issue receipts.

(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 Applicable  Legislation,  of this
         Section 9.2 and of Section 9.3

9.3               Evidence, Experts and Advisers

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

(b)      In the exercise of its rights and duties hereunder, 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  in  statutory  declarations,
         opinions,  reports,  written  requests,  consents,  or  orders  of  the
         Corporation,   certificates   of  the  Corporation  or  other  evidence
         furnished to the Trustee pursuant to a request of the Trustee, provided
         that such evidence  complies with  Applicable  Legislation and that the
         Trustee  complies  with  Applicable  Legislation  and that the  Trustee
         examines the same and determines  that such evidence  complies with the
         applicable requirements of this Indenture.

(c)      Whenever  it  is  provided  in  this  Indenture  or  under   Applicable
         Legislation  that  the  Corporation  shall  deposit  with  the  Trustee
         resolutions, certificates, reports, opinions, requests, orders or other
         documents,  it is intended  that the trust,  accuracy and good faith on
         the  effective  date thereof and the facts and  opinions  stated in all
         such  documents so  deposited  shall,  in each and every such case,  be
         conditions  precedent  to the  right  of the  Corporation  to have  the
         Trustee take the action to be based thereon.

(d)      Proof  of the  execution  of an  instrument  in  writing,  including  a
         Warrantholders'  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  acknowledged  to  it  the
         execution thereof, or by an affidavit of a witness to such execution or
         in any other manner which the Trustee may consider adequate.

(e)      The Trustee may employ or retain such Counsel, accountants,  appraisers
         or other  experts or  advisers  as it may  reasonably  require  for the
         purpose of  discharging  its duties  hereunder  and may pay  reasonable
         remuneration  for all  services so  performed  by any of them,  without
         taxation of costs of any Counsel,  and shall not be responsible for any
         misconduct  or  negligence  on the part of any such experts or advisers
         who have been appointed with due care by the Trustee.

may at any time be held by the  Trustee  subject  to the  trusts  hereof  may be

provided, any monies so held pending the application or withdrawal thereof under
any  provisions of this Indenture may be deposited in the name of the Trustee in
any  Canadian  chartered  bank at the rate of interest  (if any) then current on
similar deposits or, with the consent of the Corporation,  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; or
(ii) invested in securities  issued or guaranteed by the Government of Canada or

         verify the same,  but all such  statements or recitals are and shall be
         deemed to be made by the Corporation;

(b)      nothing herein  contained shall 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
         hereto;

(c)      the Trustee  shall not be bound to give notice to any person or persons
         of the execution hereof;

(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 Corporation of any of the covenants  herein  contained or of any
         acts of any directors,  officers,  employees, agents or servants of the
         Corporation; and

(e)      without  limiting any  protection or indemnity of the Trustee under any
         other provision  hereof,  or otherwise at law, the  Corporation  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,  including 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 willful  misconduct  of the Trustee.  This
         provision  shall survive the  resignation  or removal of the Trustee or
         the termination of this Warrant Indenture.

9.8               Replacement of Trustee; Successor by Merger

(a)      The  Trustee  may resign its trust and be  discharged  from all further
         duties and  liabilities  hereunder,  subject to this  Section  9.8,  by
         giving to the  Corporation not less than ninety (90) days' prior notice
         in writing or such shorter prior notice as the  Corporation  may accept
         as sufficient.  The  Warrantholders  by extraordinary  resolution shall
         have power at any time to remove the existing  Trustee and to appoint a
         new Trustee.  In the event of the Trustee resigning or being removed as
         aforesaid or being dissolved, becoming bankrupt, going into liquidation
         or otherwise  becoming  incapable of acting hereunder,  the Corporation
         shall forthwith  appoint a new trustee unless a new trustee has already
         been appointed by the  Warrantholders;  failing such appointment by the
         Corporation,  the retiring Trustee or any  Warrantholder may apply to a
         justice of the Court of  Queen's  Bench of the  Province  of Alberta on
         such notice as such justice may direct,  for the  appointment  of a new
         trustee;  but any new trustee so appointed by the Corporation or by the
         Court shall be subject to removal as aforesaid  by the  Warrantholders.
         Any new trustee appointed under any provision of this Section 9.8 shall
         be a Corporation authorized to carry on the business of a trust company
         in the Province of Alberta and,

         if required by the Applicable  Legislation for any other provinces,  in
         such other provinces.  On any such appointment the new trustee shall be
         vested with the same powers,  rights, duties and responsibilities as if
         it had been originally named herein as Trustee hereunder.

(b)      Upon the  appointment of a successor  trustee,  the  Corporation  shall
         promptly notify the  Warrantholders  thereof in the manner provided for
         in Section 10.2 hereof.

(c)      Any  corporation  into or with  which  the  Trustee  may be  merged  or
         consolidated or amalgamated,  or any corporation resulting therefrom or
         any  corporation  succeeding to the trust business of the Trustee shall
         be the  successor to the Trustee  hereunder  without any further act on
         its part or any of the parties hereto,  provided that such  corporation
         would  be  eligible  for  appointment  as  a  successor  trustee  under
         subsection 9.8(a).

(d)      Any Warrant  Certificates  certified but not delivered by a predecessor
         trustee may be  certified by the  successor  trustee in the name of the
         predecessor or successor trustee.

9.9               Conflict of Interest

(a)      The Trustee represents to the Corporation that at the time of execution
         and delivery hereof no material conflict of interest exists between its
         role as a  trustee  hereunder  and its role in any other  capacity  and
         agrees that in the event of a material  conflict  of  interest  arising
         hereafter it will,  within ninety (90) days after  ascertaining that it
         has such material  conflict of interest,  either  eliminate the same or
         assign its trust  hereunder  to a  successor  trustee  approved  by the
         Corporation  and  meeting  the  requirements  set  forth in  subsection
         9.8(a).

         Notwithstanding the foregoing  provisions of this subsection 9.9(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 9.9(a), the Trustee, in its personal or any other
         capacity,  may buy, lend upon and deal in securities of the Corporation
         and generally may contract and enter into financial  transactions  with
         the  Corporation  or any  Subsidiary of the  Corporation  without being
         liable to account for any profit made thereby.

9.10              Acceptance of Trust

                  The  Trustee  hereby  accepts  the  trusts  in this  Indenture
declared  and  provided  for and agrees to  perform  the same upon the terms and
conditions herein set forth.

         Trustee  may  treat  the  person  so  named  as  the  owner,  and  such
         certificate  as sufficient  evidence of the ownership by such person of
         such Warrant during such period, for the purpose of any

         execution thereof, or (iii) a satisfactory  declaration of a witness of
         such execution.

of  which  when  so  executed  shall  be  deemed  to be  an  original  and  such
counterparts   together  shall  constitute  one  and  the  same  instrument  and
notwithstanding  their date of execution  they shall be deemed to be dated as of
the date hereof.

10.6              Satisfaction and Discharge of Indenture

                  Upon the earlier of:

         (a) the date by which  there shall have been  delivered  to the Trustee

satisfaction  and discharge of this  Indenture  have been complied  with,  shall
execute proper  instruments  acknowledging  satisfaction of and discharging this
Indenture.  Notwithstanding  the  foregoing,  the  indemnities  provided  to the

4. The terms of the Special Warrant Indenture originally referenced in paragraph
2.1(a) thereof that HealthCare has created for issuance up to 5,760,000 Warrants
such number  including  all Special  Warrants  issuable to the Agents as part of

owned or to be received by them;

                  AND WHEREAS the  Trustee has agreed to  undertake  and perform
its duties according to the terms and conditions hereof;

                  NOW THEREFORE this agreement  witnesses that, in consideration
of the sum of one dollar  ($1.00) paid by the parties to each other,  receipt of
this sum being acknowledged by each of the parties, the Security Holders jointly

Issuer  and the  Trustee  covenant  and  agree  each with the other and with the
Security Holders jointly and severally as follows:

1. Where used in this  agreement,  or in any  amendment  or  supplement  hereto,
unless the context  otherwise  requires,  the following  words and phrases shall
have the following ascribed to them below:

         (a)      "Major Transaction" shall include any material  transaction in
                  accordance with the by-laws of The Alberta Stock Exchange, and
                  a transaction whereby:

                  (i)      the issuer  issues more than 25% of the number of its
                           previously  outstanding  securities to acquire assets
                           (other than cash) or securities of another issuer,

                  (ii)     the issuer enters into an arrangement,  amalgamation,
                           merger or  reorganization  with  another  issuer with
                           Significant  Assets  other  than  cash,  whereby  the
                           ration of securities which are distributed to the two
                           sets of  security  holders  results  in the  security
                           holders of the other issuer acquiring  control of the
                           resulting entity,

                  (iii)    the issuer acquires Significant Assets, or

                  (iv)     the issuer  issues more than 25% of the number of its
                           previously   outstanding   securities   for  cash  (a
                           "Private Placement");

         (b)      "Significant   Assets"  means  assets  (other  than  cash)  or
                  securities of another  issuer whereby the listed company meets
                  the minimum  listing  requirements  under  Circular No. 1 upon
                  completion of the acquisition.

2. Each of the  Security  Holders  hereby  undertakes  and  agrees to deposit in
escrow any securities of the Issuer which he has or may acquire  pursuant to the
first Major Transaction or pursuant to the exercise of any option granted to him
by the issuer pursuant to the first Major Transaction (including any replacement
securities  if an when issued)  which  securities  are described in Schedule "A"
attached to this agreement.

3. The Parties  hereby  agree that,  subject to the  provisions  of  paragraph 6
herein, the securities and the beneficial  ownership of any interest in them and
the certificate representing



                                                     - 2 -

them (including any replacement  securities or certificates)  shall not be sold,
assigned,  hypothecated,  alienated,  released from escrow,  transferred  within
escrow,  or otherwise in any manner dealt with,  without the written  consent of
the Chief of  Securities  Administration  of the Alberta  Securities  Commission
(hereinafter  referred to as the "Chief")  given to the Trustee or except as may
be required by reason of the death or  bankruptcy  of any  Security  Holder,  in
which  cases  the  Trustee  shall  hold the said  certificates  subject  to this
agreement,  for whatever person,  or company shall be legally entitled to become
the registered owner thereof.

4. The Security Holders direct the Trustee to retain their respective securities
and the  certificates  (including any  replacement  securities or  certificates)
representing  them and not to do or cause  anything  to be done to release  them
from  escrow or to allow any  transfer,  hypothecation  or  alienation  thereof,
without  the   written   consent  of  the  Chief.   The   Trustee   accepts  the
responsibilities  placed on it by the  agreement  and agrees to perform  them in
accordance with the terms of this agreement and the written consents,  orders or
directions of the Chief.

5. Any Security Holder applying to the Chief for a consent for a transfer within
escrow  shall,  before  applying,  give  reasonable  notice  in  writing  of his
intention to the Issuer and the Trustee.

6.  Notwithstanding the provisions of paragraph 4 hereof,  securities  deposited
with the Trustee  pursuant to this agreement  shall be released,  subject to the
prior  written  consent  of the  Chief,  upon  the  Issuer  completing  a  Major
Transaction  (other  than a  Private  Placement)  as to  one-third  (1/3) of the
original  number of escrowed  securities on each of the first,  second and third
anniversaries  of the  completion of the Major  Transaction.  The Chief,  in his
discretion,  may  consent to the release of  securities  on the second and third
anniversaries of the completion of the Major Transaction when consent is granted
for the release of securities on the occasion of the first anniversary.

7. A  release  from  escrow  of all or part  of the  escrowed  securities  shall
terminate this agreement  only in respect to those  securities so released.  For
greater certainty this paragraph does not apply to securities transferred within
escrow.

8. If during the period in which any of the  securities  are  retained in escrow
pursuant  hereto,  any  dividend  is  received  by the Trustee in respect of the
escrowed securities,  any such dividend shall be promptly paid or transferred to
the respective Security Holders entitled thereto.

9. All voting rights attached to the escrowed  securities  shall at all times be
exercised by the respective registered owners thereof.

10. The Security  Holders  hereby  jointly and severally  agree to and do hereby
release and indemnify and save harmless the Trustee from and against all claims,
suits, demands, costs, damages and expenses which may be occasioned by reason of
the Trustee's compliance in good faith with the terms hereof.

binding on the Security  Holders,  and the new Trustee shall assume and be bound
by the obligations of the Trustee hereunder.

13. The covenants of the Security  Holders with the Issuer in this agreement are
made with the Issuer both in its own right and as trustee  for the holders  from
time to time of free  securities in the Issuer,  and may be enforced not only by
the Issuer but also by any holder of free securities.

14. This  agreement  may be  executed in several  parts of the same form and the
parts as so executed shall together constitute one original  agreement,  and the
parts,  if more than one,  shall be read  together  and  construed as if all the
signing parties hereto and executed one copy of this agreement.

to this agreement and each of their heirs, executors, administrators, successors
and assigns.

                  IN WITNESS  WHEREOF  the Issuer and the  Trustee  have  caused

3. The Parties  hereby  agree that,  subject to the  provisions  of  paragraph 6

and the certificate  representing them (including any replacement  securities or
certificates) shall not be sold,  assigned,  hypothecated,  alienated,  released

person,  or company  shall be legally  entitled to become the  registered  owner
thereof.

4. The Security Holders direct the Trustee to retain their respective securities
and the  certificates  (including any  replacement  securities or  certificates)
representing  them and not to do or cause  anything  to be done to release  them

                  (a)    The Exchange will consent to the release from escrow on
                         the following basis:

                          (i)    one share for each $0.11 of cash flow generated
                                 by or from the property.

                  (b)    Any release from escrow under  paragraph  6(a)(i) shall
                         be made pursuant to a written  application on behalf of
                         the Issuer or the Security  Holders,  which application
                         shall be  accompanied  by  evidence  of the  Cash  Flow
                         received  in  a  form  satisfactory  to  the  Exchange.
                         Application  for release may only be made once per year
                         and may only  relate to Cash Flow  received or Deferred
                         Expenditures  incurred in the preceding  fiscal year or
                         the fiscal  years of the Issuer  since the last release
                         from escrow  pursuant to this  agreement,  whichever is
                         greater.  All shares released from escrow shall, unless
                         otherwise  directed  by the  Exchange,  be  distributed
                         pro-rata to all Security Holders.

                  (c)    Notwithstanding  subparagraph  (b) above,  the  maximum
                         number of shares

                         to be  released  from  escrow in any year to a Security
                         Holder who is a Related Party shall be one third of the
                         original  number of shares  held in escrow on behalf of
                         such Security Holder.

7. A  release  from  escrow  of all or part  of the  escrowed  securities  shall
terminate this agreement  only in respect to those  securities so released.  For
greater certainty this paragraph does not apply to securities transferred within
escrow.

8. The  Security  Holders  shall,  if a dividend is declared  while the Escrowed
Shares  or any of them  continue  to be held in  escrow  under  this  Agreement,
renounce and release any right to receive  payment of the dividend on the shares
then held in escrow.

9. If the  Issuer is wound up and any  securities  remain in escrow  under  this
agreement at the time when a distribution  of assets to holders of securities is
made by the liquidator, the Security Holders shall assign their right to receive
that part of the distribution  which is attributable to the escrowed  securities
to the Trustee,  for the benefit of, and in trust for the persons and  companies
who are then holders of free securities in the Issuer rateably in proporation to
their holdings.

10.

                  (a)    In the event that the Issuer has lost, alienated or has
                         not  obtained  a good or  marketable  title  to, or has
                         abandoned or discontinued development of, any or all of
                         the aforesaid  property which was or formed part of the
                         consideration  for which the aforesaid  securities were
                         issued,  or that  any or all of the said  property  has
                         become of little or no value,  the issuer shall declare
                         the  occurrence  of that event,  with full  particulars
                         thereof,  to  the  Exchange  by  a  resolution  of  its
                         directors, and those Security Holders who are directors
                         from time to time hereby agree to cause such resolution
                         to be passed and certified to the  satisfaction  of the
                         Exchange.

                  (b)    The Security  Holder  jointly and severally  agree with
                         the  Issuer  and the  Trustee  that in the event of any
                         such loss, alienation,  failure to acquire title, or of
                         such  abandonment or  discontinuance  of development or
                         diminution  of  value,  the  securities  held in escrow
                         shall not be  cancelled  or released  from  escrow,  in
                         whole  or in  part,  except  with  the  consent  of the
                         Exchange.

                  (c)    The Exchange may, in its sole discretion, having regard
                         to the  number and value of the  securities  issued for
                         the  property,  the value of the property as ultimately
                         established  and  such  other  circumstances  as it may

                         to be cancelled or released and shall  communicate  its
                         decision  in writing to the  Trustee.  If the  Exchange
                         determines  that less than all the securities then held
                         in  escrow  shall  be   cancelled   or  released,   the
                         securities  to be cancelled or released  shall be taken
                         rateably from the escrowed  security holding of each of
                         the Security

                         gift for  cancellation  and, the Issuer shall thereupon
                         take  the  necessary  action,  by way of  reduction  of
                         capital  or   otherwise,   to  cancel  them,   and  the
                         certificates for these securities shall be delivered up
                         for cancellation by the Issuer's transfer agent.

                  (e)    Each of the Security  Holders  undertakes and agrees to
                         vote and cause to be voted their respective  securities

                         gifting back of securities for cancellation.

                                AGENCY AGREEMENT




HEALTHCARE CAPITAL CORP.                                         August 22, 1996
1120-595 Howe Street
Vancouver, B.C.
V6C 2T5

ATTENTION:        DOUGLAS F. GOOD

Dear Sirs:

C.M. Oliver & Company Limited (the "Agent")  understands that HealthCare Capital
Corp. (the "Company") proposes to create and issue 4,800,000 special warrants of
the  Company  having  the  attributes  and  characteristics  specified  in  this
agreement  (the "Special  Warrants").  Upon its acceptance of this agreement and
subject to the terms and  conditions  set forth in this  agreement,  the Company
hereby appoints the Agent to act as the Company's  project manager and exclusive
agent in  Canada  to use its best  efforts  to  effect  the sale of the  Special
Warrants at a price of $1.25 (U.S.) per Special Warrant,  for an aggregate price
of up to $6,000,000 (U.S.) ("Aggregate Purchase Price"), and the Agent agrees to
act as the Company's agent to use its reasonable best efforts to effect the sale
of the Special  Warrants in Canada on the Company's  behalf.  In so acting,  the
Agent is under no obligation to purchase any of the Special  Warrants,  although
the Agent may  subscribe  for Special  Warrants  if it so  desires.  The Company
reserves  the  right to  reject  subscriptions,  at its  discretion,  only if it
considers  acceptance  not to be in the  best  interests  of the  Company  or if
acceptance of the Subscription would obligate the Company to issue and sell more
than 4,800,000 Special Warrants.

The closing of the issue and sale of the Special Warrants will take place in two
tranches, as follows:

                  (a)      the first  tranche and closing (the "First  Closing")
                           will  include  only  subscribers  who are  not  "U.S.
                           Persons"  within the meaning of  Regulation  S of the
                           U.S. Securities and Exchange Commission; and

                  (b)      a second  tranche and closing (the "Second  Closing")
                           will include only subscribers who are "U.S. Persons".

All offers and sales of the  Special  Warrants  to "U.S.  Persons"  will be made
directly by the Company  through duly registered  U.S.  broker-dealers,  who are
members of the selling group organized by the Agent and the Company.

In  consideration  of the services to be rendered by the Agent to the Company in
effecting the sale of the Special Warrants and as corporate advisor, the Company
agrees  to  pay to the  Agent,  at the  time  and  in the  manner  specified  in
subsection 5.3:

                  (a)      a fee  (the  "Fee")  equal  to 9%  of  the  Aggregate
                           Purchase  Price of the Special  Warrants  sold by the
                           Company on the First  Closing  payable at the time of
                           Closing of the issue and sale of the Special Warrants
                           (a "Closing  Date"),  in cash, in Special Warrants or
                           in a combination thereof, as directed by the Agent;

                  (b)      a corporate finance fee of $50,000 (Cdn.);

                  (c)      a  syndication  fee  of  1%  of  the  gross  proceeds
                           received by the Company  from the sale of all Special
                           Warrants,  payable at the  Agent's  option in cash or
                           Special Warrants; and



                                                     - 1 -

                  (d)      a special option (the "Agent's Option") entitling the
                           Agent to acquire  warrants  to  purchase up to 10% of
                           the number of the Special  Warrants sold by the Agent
                           on the first  tranche (the "Option  Warrants")  which
                           shall be  exercisable  into  that  number  of  common
                           shares  (the  "Option  Shares")  of the  Company at a
                           price of $1.25 (U.S.) per share until August 31, 1998
                           unless cancelled  earlier,  as described below.  Upon
                           the  acceptance  for  listing  or  quotation  of  the
                           Company's  shares on a recognized  stock  exchange or
                           national trading market in the United States,  if the
                           closing bid for the Company's shares is not less than
                           $3.00  (U.S.)  per  share  for  a  period  of  twenty
                           consecutive  trading days,  the Company will have the
                           option,  on 45 days  written  notice,  to  force  the
                           exercise or cancellation of the Agent's Option.

The Agent's Option to acquire the Option  Warrants may be exercised by the Agent
without any further  action on its part,  at any time during the 12 month period
following the Closing Date,  and in any event shall be deemed to be exercised on
the 5th  business  day  following  the day on which a receipt  is issued for the
Final  Prospectus (as hereinafter  defined) by the last of the British  Columbia
Securities  Commission  and any  other  securities  regulatory  authority  for a
Canadian  Province or  Territory  in which a trade in the Special  Warrants  has
taken place (the "Qualification Date"), or the date which is 12 months following
the Closing Date, whichever is earlier.


1.                TERMS OF THE SPECIAL WARRANTS

1.1 The Special  Warrants will be issued under and governed by a trust indenture
(the "Special  Warrant  Indenture") to be dated as of the First Closing Date and
to be made  between  the  Company  and The R-M Trust  Company  (the  "Trustee").
Subject to subsection  1.3, each Special  Warrant will entitle the holder,  upon
exercise and without payment of any additional  consideration,  to be issued one
common  share in the  capital of the  Company  (an  "Underlying  Share") and one
non-transferrable   share  purchase  warrant  (an  "Underlying  Warrant").   The
Underlying  Warrants will be issued under and governed by a trust indenture (the
"Purchase Warrant  Indenture") to be dated as of the Closing Date and to be made
between the Company and the Trustee.  Each  Underlying  Warrant will entitle the
holder  thereof to acquire  one common  share in the  capital of the Company (an
"Underlying  Warrant  Share") at a price of $2.00  (U.S.) per share until August
31, 1998,  subject to earlier  cancellation as described  below.  The Underlying
Shares and the  Underlying  Warrants  will be  collectively  referred  to as the
"Underlying Securities".

1.2 The Company  covenants  to, and, if required by the Agent,  the Company will
covenant under the Special Warrant Indenture that it will:

                  (a)      prepare and file,  using its reasonable  best efforts
                           to do so on or  before  the day which is 45 days from
                           the  First   Closing  Date,   under  the   applicable
                           securities  laws,  regulations  and rules of  British
                           Columbia  and  such  other   Canadian   Provinces  or
                           Territories  in  which a trade  in  Special  Warrants
                           takes    place    (collectively    the    "Qualifying
                           Jurisdictions"),   a  preliminary   prospectus   (the
                           "Preliminary Prospectus"), together with the required
                           supporting documents,  to qualify the distribution of
                           the Underlying Securities and the Option Warrants;

                  (b)      use  its  reasonable   best  efforts  to  address  as
                           expeditiously   as  possible  the  comments  made  in
                           respect  of  the   Preliminary   Prospectus   by  the
                           securities  regulatory  authorities  (the "Securities
                           Commissions") of the Qualifying Jurisdictions; and

                  (c)      prepare and file,  using its reasonable  best efforts
                           to do so on or before  the day which is 120 days from
                           the  Second   Closing  Date,   under  the  applicable
                           securities  laws of the Qualifying  Jurisdictions,  a
                           final prospectus (the "Final  Prospectus"),  together

                           further  action  on  their  part,  at any time on the
                           fifth business day following the Qualification Date;

                  (c)      any Special  Warrants then outstanding will be deemed
                           to be exercised on the day which is one year from the
                           First Closing Date (the "Expiry Date"); and

                  (d)      if a receipt for the Final  Prospectus  is not issued
                           by the Securities  Commissions within 120 days of the

of  obtaining  any  order  or  ruling  of  any of  the  Securities  Commissions.
Notwithstanding that offers and sales of Special Warrants may be made outside of

make all required filings which must be made in order to effect  compliance with
such laws, regulations, rules and policies.

The Agent will notify the Company with respect to the identity and  jurisdiction
of residence of each Purchaser as soon as  practicable  with a view to affording
sufficient  time to allow the Company to secure  compliance  with the Applicable
Securities Laws and the applicable law and policy in the Offering  Jurisdictions
in connection with the sale of the Special  Warrants to the Purchasers under the
exemptions referred to above (collectively the "Exemptions").

2.2 The Company will, at its own expense,  comply with the Applicable Securities
Laws in  connection  with the sale of the Special  Warrants  to the  Purchasers,
including the filing of required  reports and the payment of any applicable fees
relating thereto.

Laws in  connection  with  obtaining  the  receipt for the Final  Prospectus  to
qualify  the  distribution  of the  Underlying  Securities  and Option  Warrants
including the filing of required  reports and the payment of any applicable fees
relating thereto.

2.4 The Agent will conduct its activities in connection with the distribution of
the Special  Warrants in compliance  with all  Applicable  Securities  Laws and,
without limiting the foregoing, the Agent represents, warrants and agrees, that:

                  (a)      all solicitation,  offering and other selling efforts
                           carried out by it in connection with the distribution

                           and all  purchases of Special  Warrants will be made,
                           in accordance  with the provisions of the Exemptions;
                           and

                  (b)      it is a  member,  in good  standing,  of The  Alberta
                           Stock Exchange (the "Exchange").

2.5 The Agent will obtain  from each  Purchaser  a properly  completed  and duly
executed  subscription  agreement  (a  "Subscription  Agreement"),  in the  form
provided by the Company,  and a properly  completed  and duly  executed  private
placement questionnaire and undertaking (a "Questionnaire and Undertaking"),  in
the form attached to the  Subscription  Agreement,  and for those Purchasers who
are  individuals in  circumstances  where the B.C. Act applies a Form 20A(IP) in
the form attached to the Subscription Agreement.

2.6 The Agent  will not offer or sell the  Special  Warrants  or the  Underlying
Securities in the United States and makes the  representations,  warranties  and
covenants set forth in Part II of Schedule "A", which are incorporated  into and
form part of this agreement.

                           contained  in  the  Prospectuses,  any  Supplementary

                           available for inspection;

                  (c)      any order made by any  securities  commission,  stock

                           liabilities   or   expenses   arise  from  the  gross
                           negligence or bad faith of the Agent; or

                  (e)      any other  breach by the  Company of any of the terms

9.2 If any matter  contemplated  by  subsection  9.1 is asserted in an action or
claim  against  any one or more of the  Indemnified  Persons in respect of which
matter  indemnity may be sought against the Company  pursuant to this agreement,
or any  potential  action or claim  comes to their  knowledge,  the  Indemnified
Person  will  notify the Company as soon as possible in writing of the nature of
the action or claim and the Company  will be entitled to (but not  required  to)
assume the defence of that action or claim,  including  the  employment of legal
counsel  (satisfactory to the Indemnified Person,  acting reasonably) and assume
payment of the expenses in relation thereto.  Each Indemnified  Person will have
the  right to  employ  separate  legal  counsel  in any  action  or claim and to
participate  in the defence  thereof,  but the fees and expenses of that counsel
will be at the expense of the Indemnified Person and not of the Company unless:

                  (a)      the   employment  of  that  legal  counsel  has  been
                           specifically  authorized in writing by the Company in
                           connection with the defence of the action or claim;

                  (b)      the Company has not,  within five business days after
                           having  received  written  notice  of the  action  or
                           claim,  employed legal counsel to have conduct of the
                           defence of the action or claim; or

                  (c)      the named  parties to any action or claim  (including
                           any added,  third or  interpleaded  parties)  include
                           both the Indemnified Person and the Company, and such
                           Indemnified  Person has been  advised by counsel that
                           there may be defenses  available  to the  Indemnified
                           Person  which are  different  from or  additional  to
                           those  available  to the  Company  (in which case the
                           Company  will not have the  right to assume or direct
                           the  defence  of the action or claim on behalf of the
                           Indemnified Person);

Notwithstanding  the  foregoing,  no settlement  may be made by the  Indemnified
Person concerned  without the prior written consent of the Company which consent
will not be unreasonably withheld.

                  or television,  or any seminar or meeting whose attendees have
                  been invited by general solicitation or general advertising.

         (e)      Prior to any sale of Special Warrants in the United States, it

3. The Company agrees to obtain  substantially  identical  undertakings from any
placement  agent  engaged in  connection  with the  distribution  of the Special
Warrants  contemplated  hereby.  The  Company has not entered and will not enter
into any contractual arrangement with respect to the distribution of the Special
Warrants, except with the prior written consent of the Agent.

4. The Company is not an open-end  investment  company or unit investment  trust
registered  or  required  to be  registered  or  closed-end  investment  company
required  to  be  registered,  but  not  registered,  under  the  United  States

         2. APPOINTMENT OF DALLAS  RESEARCH.  The Company hereby appoints Dallas
Research as its co-agent to solicit  subscriptions  in the United  States,  on a
best efforts basis, for up to 2,000,000 Special Warrants  constituting a part of

conditions set forth herein, the Company and Dallas Research agree as follows:

                  (a)  REGULATION D OFFERING.  Neither the offer nor the sale of

         States Securities and Exchange  Commission (the "Commission") under the
         United  States  Securities  Act of 1933,  as amended  (the  "Securities
         Act").  The Special  Warrants  will be offered and sold pursuant to the
         Dallas  Research  Offer in  reliance  upon and in  compliance  with the

         only be sold to  "accredited  investors" as such term is defined in Reg
         D. Such Special  Warrants will be offered for sale only in those states
         in which the Special  Warrants  shall have been qualified or registered
         for sale or are exempt from such  qualification  or  registration.  The
         Company will provide Dallas Research,  for delivery to all offerees and
         purchasers  and  their  representatives,  copies of the  United  States
         Confidential  Offering Memorandum dated October 16, 1996 of the Company
         (the   "Memorandum")   and  such  other   information,   documents  and
         instruments  which Dallas  Research deems  necessary to comply with the
         statutes,   rules,   regulations   and  judicial   and   administrative
         interpretations applicable to the Dallas Research Offer.

                  (b)  SUBSCRIPTION  FOR SPECIAL  WARRANTS.  Purchase of Special
         Warrants  shall occur by execution  and delivery by a Subscriber of two

         Memorandum  (the  "Subscription  Agreement"),  together with such other
         documents and  instruments as the Company or Dallas Research shall deem
         appropriate.

                  (c)  PAYMENT.  Each  Subscriber  shall  tender a cashier's  or
         certified check payable to HealthCare  Capital Corp., in payment of the

         1996 or such later date as may be  mutually  agreed upon by the Company
         and Dallas Research (the "Final Closing Date").  By mutual agreement of
         the Company  and Dallas  Research,  an interim  closing  (the  "Initial
         Closing")  of the Dallas  Research  Offer may occur  prior to the Final

         Closing  against  payment  therefor as provided in Section 3(c) of this
         Agreement. In the event that no Special Warrants are sold hereunder, on
         the  Final  Closing  Date  all  terms  of  this   Agreement   shall  be
         automatically  terminated  and  neither  party  shall have any  further
         obligation  to the other  party  under  this  Agreement  other than the
         Company's  obligation to pay expenses as set forth in Section 9 of this
         Agreement.

         Special Warrant; and

                  (b) A  special  option in the form of  Exhibit  A hereto  (the

         Common  Shares  in a  number  equal  to 10% of the  number  of  Special
         Warrants sold at such Closing.

In addition,  at each Closing the Company shall,  to the extent not  theretofore

         with the terms of the Subject  Agreements do not, and will not, with or

         imposition of any lien,  security interest,  charge or encumbrance upon
         any  of  the  properties  or  assets  of  the  Company  or  any  of its

         commitment or other agreement or instrument to which the Company or any
         Subsidiary is a party or by which the Company or any  Subsidiary or any
         of its or their  properties  or assets are or may be bound or affected;
         (iii) violate any existing applicable law, rule, regulation,  judgment,
         order or  decree of any  governmental  agency  or  court,  domestic  or
         foreign,  having jurisdiction over the Company or any Subsidiary or its
         or their  properties  or business;  or (iv) have any  material  adverse
         effect on any permit, certification,  registration,  approval, consent,
         license or franchise necessary for the Company or any Subsidiary to own
         or lease and operate any of its  properties and to conduct its business
         or the ability of the Company or such Subsidiary to make use thereof.

         contained in the  Memorandum  under the caption  "Description  of Share
         Capital" conform to such description. All the outstanding Common Shares
         have



                                                     - 5 -

         been  duly  authorized  and  validly  issued  and are  fully  paid  and
         nonassessable.  Except as set  forth in the  Memorandum  and  except as
         contemplated  by the  Offering,  there are,  and until the Closing Date
         there will be, no outstanding securities convertible into Common Shares
         ("Convertible  Securities") or any options, warrants or other rights to
         purchase any Common Shares or Convertible Securities  ("Options").  All
         such outstanding  Options constitute the valid and binding  obligations
         of the  Company,  enforceable  against the Company in  accordance  with
         their respective terms. None of the outstanding Common Shares,  Options
         or  Convertible  Securities  have  been  issued  in  violation  of  any
         preemptive or similar right of any  securityholder of the Company,  and
         none of the  holders  of the  outstanding  Common  Shares,  Options  or
         Convertible  Securities  is subject  to  personal  liability  solely by
         reason of being such a holder.  The offers and sales of the outstanding
         Common Shares,  Options and Convertible Securities were at all relevant
         times exempt from  registration or  qualification  under the Securities
         Act and any applicable  Blue Sky Laws and were in full  compliance with
         all applicable  Canadian federal and provincial laws and stock exchange
         regulations.  Except as  provided  in  Exhibit B hereto  and except for
         registration  rights granted in connection  with the acquisition by the
         Company of Hearing Care  Associates and proposed to be granted,  in the
         "SONUS"  acquisition  described in the Memorandum,  no holder of any of
         the Company's issued securities has any rights  ("demand,"  "piggyback"
         or otherwise) to have such securities  registered  under the Securities
         Act.

                  (f)  AUTHORIZATION  OF SHARES AND  WARRANTS.  The issuance and
         sale of the Special Warrants (including the Compensation Warrants), the
         Dallas Research Option and the securities issuable upon the exercise of
         any of the  foregoing  and of the  Warrants  and  the  Dallas  Research
         Warrants have been duly authorized,  and when issued as contemplated by
         the indentures or agreements  relevant thereto,  will be validly issued
         and fully paid and  nonassessable,  and the holders thereof will not be
         subject to personal  liability  solely by reason of being such holders.
         None of such  securities is or will be subject to preemptive  rights of
         any securityholder of the Company.

                  (g)  NO   ANTI-DILUTION   ADJUSTMENT.   The  issuance  of  the
         securities  of the  Company  contemplated  by this  Agreement  will not
         result  in any  adjustment  in the  number  of  Common  Shares,  or the
         exercise price or conversion  ratio per Common Share,  under any of the
         Company's outstanding Options or Convertible Securities.

                  (h)  NONCONTRAVENTION.  Neither  the  Company  nor  any of its
         Subsidiaries  is in  violation  of, or in  default  under,  any term or
         provision  of  (i)  its  constating  documents,   (ii)  any  indenture,
         mortgage,  contract,  commitment  or other  agreement or  instrument to
         which it is a party or by which it or any of its properties or business
         is or may be bound or subject,  or (iii) any existing  applicable  law,
         rule, regulation,  judgment, order or decree of any governmental agency
         or court,  Canadian or otherwise,  having jurisdiction over the Company
         or the Subsidiary or any of their respective  properties or businesses.
         The Company and each  Subsidiary  owns,  possesses  or has obtained all
         governmental    and   other    licenses,    permits,    certifications,
         registrations, approvals or consents and other authorizations necessary
         to own or lease, as the case may be, and to operate its



                                                     - 6 -




<PAGE>



         properties  and to conduct its  business  as  currently  conducted  and
         described  in  the   Memorandum,   and  all  such  licenses,   permits,
         certifications,    registrations,   approvals,   consents   and   other
         authorizations are in good standing.  There are no proceedings  pending
         or, to the best of the Company's  knowledge,  threatened,  nor is there
         any basis  therefor,  seeking  to cancel,  terminate  or limit any such
         licenses, permits, certifications, registrations, approvals or consents
         or authorizations.

                  (i) LITIGATION.  Except as set forth in the Memorandum,  there
         are   no   claims,   actions,   suits,    proceedings,    arbitrations,
         investigations  or inquiries before any governmental  agency,  court or
         tribunal,  Canadian or  otherwise,  or before any  private  arbitration
         tribunal,   pending  or,  to  the  best  of  the  Company's  knowledge,
         threatened  against  the Company or any  Subsidiary  or  involving  the
         properties  or  business  of the Company or any  Subsidiary  which,  if
         determined adversely,  would, individually or in the aggregate,  result
         in any material adverse change in the financial position, shareholders'
         equity,  results of  operations,  properties,  business,  management or
         affairs of the Company and the Subsidiaries  taken as a whole, or which
         relate in any way to the  validity of the capital  stock of the Company
         or the  validity  of this  Agreement,  or of any action  taken or to be
         taken by the Company pursuant to, or in connection with this Agreement,
         nor, to the best of the Company's knowledge, is there any basis for any
         such claim, action,  suit,  proceeding,  arbitration,  investigation or
         inquiry.  There are no outstanding orders,  judgments or decrees of any
         court,  governmental  agency or other tribunal  specifically naming the
         Company or any  Subsidiary  and enjoining the Company or any Subsidiary
         from taking,  or requiring the Company or any  Subsidiary to take,  any
         action,  or to which  the  Company  or any  Subsidiary  or its or their
         properties or business is bound or subject.

                  (j)  FINANCIAL  STATEMENTS.  Shikaze  Ralston,  the  chartered
         accountants  who have  rendered a report with respect to the  financial
         statements   included  in  the  Memorandum,   are  "independent  public
         accountants"   within  the  meaning  of  the  Securities  Act  and  the
         regulations   promulgated  under  the  Securities  Act.  The  financial
         statements  and notes thereto  included in the  Memorandum are complete
         and correct and present fairly the financial position of the Company as
         of the dates  thereof,  and the  results of  operations  and changes in
         financial  position of the Company for the periods  indicated  therein,
         all in conformity  with  generally  accepted  accounting  principles in
         Canada applied on a consistent basis throughout the periods involved.

                  (k)  LIABILITIES.  Except as and to the  extent  reflected  or
         reserved against in the financial statements of the Company included in
         the  Memorandum,  the  Company  as at July 31,  1996,  had no  material
         liabilities,  debts, obligations or claims asserted against it, whether
         accrued,  absolute,  contingent  or  otherwise,  and  whether due or to
         become due,  including,  but not limited to,  liabilities on account of
         taxes,  other  governmental  charges or lawsuits brought  subsequent to
         such date.

                  (l) TAXES.  The Company and each  Subsidiary has filed all tax
         returns required to be filed with the appropriate taxing authorities in
         Canada  and  the  United  States,  including  all  provincial,   state,
         municipal and other local authorities (whether



                                                     - 7 -

         relating to income,  sales,  franchise,  withholding,  real or personal
         property or other types of taxes) or has duly  obtained  extensions  of
         time for the filing thereof,  and has paid in full all taxes which have
         become due  pursuant  to such  returns or claimed to be due by any such
         taxing  authority or otherwise due and owing;  and the  provisions  for
         income  taxes  payable,  if any,  shown on the  consolidated  financial
         statements  contained in the  Memorandum are sufficient for all accrued
         and unpaid taxes,  whether or not disputed,  and for all periods to and
         including the dates of such consolidated financial statements.  Each of
         the tax returns  heretofore  filed by the  Company and each  Subsidiary
         correctly  and  accurately  reflects  the  amount of its tax  liability
         thereunder. The Company and each Subsidiary has withheld, collected and
         paid all  other  levies,  assessments,  license  fees and  taxes to the
         extent  required and, with respect to payments,  to the extent that the
         same have become due and  payable.  Except as  disclosed  in writing to
         Dallas Research, neither the Company nor any Subsidiary has executed or
         filed with any taxing  authority,  United States,  Canada or otherwise,
         any agreement  extending the period for assessment or collection of any
         income taxes and is not a party to any pending  action or proceeding by
         any  foreign  or  domestic   governmental   agency  for  assessment  or
         collection  of taxes,  and no claims for  assessment  or  collection of
         taxes have been asserted against the Company.

                  (m)  CONDUCT OF  BUSINESS.  Since the  respective  dates as of
         which  information is given in the Memorandum,  neither the Company nor
         any  Subsidiary has (i) canceled,  without  payment in full, any notes,
         loans or other obligations  receivable or other debts or claims held by
         it other than in the ordinary course of business;  (ii) sold, assigned,
         transferred,  abandoned, mortgaged, pledged or subjected to lien any of
         its properties,  tangible or intangible,  or rights under any contract,
         permit, license, franchise or other agreement other than sales or other
         dispositions of goods or services in the ordinary course of business at
         customary terms and prices; (iii) increased the compensation payable to
         any of its officers,  directors or other employees (including salaries,
         fringe  benefits,  pensions,  profit  participations  and  payments  or
         benefits of any kind whatsoever but excluding an increase of US $20,000
         in the base annual salary of the Vice-President  Finance); (iv) entered
         into any line of business  other than that conducted by it on such date
         or  entered  into any  transaction  not in the  ordinary  course of its
         business;  (v)  conducted  any line of business in any manner except by
         transactions customary in the operation of its business as conducted on
         such date; or (vi) declared,  made or paid or set aside for payment any
         cash or non-cash distribution on any shares of its capital stock.

                  (n)  PROPERTIES.  The Company and each Subsidiary has good and
         marketable title in fee simple to all real property,  and good title to
         all personal property (tangible and intangible),  owned by it, free and
         clear  of  all   security   interests,   charges,   mortgages,   liens,
         encumbrances  and  defects,   except  such  as  are  described  in  the
         Memorandum  or  such  as  do  not   materially   affect  the  value  or
         transferability  of such property and do not interfere  with the use of
         such  property  made or  proposed  to be made  by the  Company  or such
         Subsidiary.  The leases,  licenses or other  contracts  or  instruments
         under  which  the  Company  and  each  Subsidiary  leases,  holds or is
         entitled to use any property,  real or personal, are valid,  subsisting
         and  enforceable  only with such  exceptions as are not material and do
         not interfere with the use of such property made, or proposed to be



                                                     - 8 -




<PAGE>



         made, by the Company or such Subsidiary,  and all rentals, royalties or
         other payments  accruing  thereunder which became due prior to the date
         of this  Agreement have been duly paid, and neither the Company nor any
         Subsidiary is in default  thereunder  and, to the best of the Company's
         knowledge, no event has occurred which, with the passage of time or the
         giving of  notice,  or both,  would  constitute  a default  thereunder.
         Neither the  Company  nor any  Subsidiary  has  received  notice of any
         violation  of any  applicable  law,  ordinance,  regulation,  order  or
         requirement relating to its owned or leased properties.

                  (o) INSURANCE.  The Company and each Subsidiary has adequately
         insured its properties against loss or damage by fire or other casualty
         and maintains, in adequate amounts, such other insurance, including but
         not  limited  to,  liability  insurance,  as is usually  maintained  by
         prudent companies engaged in the same or similar businesses.

                  (p)  CONTRACTS.  Each  contract or other  instrument  (however
         characterized or described) to which the Company or any Subsidiary is a
         party,  or to which the  Company's or any  Subsidiary's  properties  or
         businesses are or may be subject,  has been duly and validly  executed,
         is in full force and effect in all material respects and is enforceable
         against the parties thereto in accordance  with its terms,  and none of
         such  contracts or  instruments  has been  assigned by the Company or a
         Subsidiary.  Neither the Company nor the Subsidiary nor, to the best of
         the Company's knowledge, any other party to such contract or instrument
         is in default  thereunder and, to the best of the Company's  knowledge,
         no event has  occurred  which,  with the lapse of time or the giving of
         notice,  or both,  would constitute a default  thereunder.  None of the
         material  provisions  of such  contracts  or  instruments  violates any
         existing applicable law, rule, regulation, judgment, order or decree of
         any governmental  agency or court having  jurisdiction over the Company
         or  any  Subsidiary  or  any of its  or  such  Subsidiary's  assets  or
         businesses.

                  (q) EMPLOYMENT AGREEMENTS. The employment agreements described
         in the  Memorandum  under the  caption  "Management  and  Directors  --
         Employment and Consulting  Agreements" are valid and binding agreements
         enforceable  against  the  Company  and the  respective  other  parties
         thereto  in  accordance  with  their  terms,  except  insofar  as  such
         enforceability  may be limited by  applicable  bankruptcy,  insolvency,
         moratorium or other similar laws or arrangements  affecting  creditors'
         rights generally and subject to principles of equity.

                  (r) BENEFIT PLANS.  Except for the Incentive Stock Option Plan
         described  in the  Memorandum  under the  caption  "Options to Purchase
         Shares," the Company has no employee benefit plans (including,  without
         limitation,  profit  sharing  and  welfare  benefit  plans) or deferred
         compensation arrangements.

                  (s)  CONTRIBUTIONS.  Neither the  Company nor any  Subsidiary,
         directly or indirectly,  at any time (i) made any  contributions to any
         candidate for political  office,  or failed to disclose  fully any such
         contribution  in  violation  of law,  or (ii) made any  payment  to any
         governmental  officer or official,  or other person charged with public
         or



                                                     - 9 -




<PAGE>



         quasi-public duties,  other than payments or contributions  required or
         allowed by applicable law.

                  (t)  REG  D  QUALIFICATION.  Subject  to  the  warranties  and
         covenants  of Dallas  Research  in Section 7.2 of this  Agreement,  the
         offer and sale of the Special  Warrants by the Company  have  satisfied
         and on each Closing Date will have satisfied,  all of the  requirements
         of Rule  506 of Reg D, and the  Company  is not  disqualified  from the
         exemption  under  Rule  506 of Reg D by  virtue  of  Rule  507 of Reg D
         because neither it, nor any of its  predecessors or affiliates has been
         subject to any  order,  judgment,  or decree of any court of  competent
         jurisdiction  temporarily,  preliminarily or permanently enjoining such
         person for failure to comply with Rule 503 of Reg D.

                  (u) FINDER'S FEE. Except for amounts paid or payable  pursuant
         to  the  Agency  Agreement,  this  Agreement  and  the  U.S.  Placement
         Agreement  dated the date hereof  between the Company and Sunrise  (the
         "Sunrise Research  Agreement"),  neither the Company nor any Subsidiary
         incurred any liability  for, or is aware of any claim for, any finder's
         or broker's fees or similar payments in connection with the Offering.

                  (v)  INTANGIBLES.  The  Company  and each  Subsidiary  owns or
         possesses  adequate and enforceable  rights to use all patents,  patent
         applications,  trademarks,  service marks,  copyrights,  rights,  trade
         secrets,  confidential information,  processes and formulations used or
         proposed  to be  used  in the  conduct  of its  business  as  currently
         conducted  (collectively,  the  "Intangibles").  To  the  best  of  the
         Company's  knowledge,  neither  the  Company  nor  any  Subsidiary  has
         infringed upon, or is presently  infringing  upon, the rights of others
         with  respect to the  Intangibles,  and  neither  the  Company  nor any
         Subsidiary  has  received  (i)  any  notice  that  it has  or may  have
         infringed  or is  infringing  upon the rights of others with respect to
         the  Intangibles,  or (ii) any  notice of  conflict  with the  asserted
         rights of others with respect to the Intangibles which could, singly or
         in the  aggregate,  materially  and  adversely  affect its  business as
         presently conducted or its prospects, financial condition or results of
         operations, and the Company does not know of any basis therefor. To the
         best of the  Company's  knowledge,  no others have  infringed  upon the
         Intangibles.

                  (w) LABOR RELATIONS. Except as disclosed in the Memorandum, no
         labor problem exists with the Company's employees or, to its knowledge,
         is imminent, which could have a material adverse effect on the Company.

                  (x) NO ADVERSE  CHANGE.  Since the date of the latest  audited
         financial  statements in the Memorandum,  except as otherwise stated in
         the Memorandum, the Company has not (i) incurred any material liability
         or  obligation,  direct or  contingent,  or entered  into any  material
         transaction,  whether or not in the  ordinary  course of  business,  or
         sustained  any material  loss or  interference  with its business  from
         fire, storm, explosion, flood or other casualty, whether or not covered
         by  insurance,  or from any  labor  dispute  or  court or  governmental
         action, order or decree, and (ii) there have not been, and prior to the
         Final  Closing Date there will not be, any changes in the capital stock
         or any material  increases in the long-term  debt of the Company or any
         material



                                                     - 10 -

         adverse  change  in  or  affecting  the  general  affairs,  management,
         financial  condition,  shareholders'  equity,  results of operations or
         prospects of the Company.

         In addition,  any  certificate  signed by an officer of the Company and
delivered to Dallas Research, or to counsel for Dallas Research, shall be deemed
to be a representation  and warranty by the Company to Dallas Research as to the
matters covered thereby.

         6.       COVENANTS OF THE COMPANY.

                  (a)  PLACEMENT  MEMORANDUM.  The Company will  furnish  Dallas
         Research,  without  charge,  with as many copies of the  Memorandum  as
         Dallas Research may reasonably request.  If, prior to the Final Closing
         Date, any event occurs as the result of which the  Memorandum,  as then
         amended  or  supplemented,  would  include  an  untrue  statement  of a
         material  fact, or omit to state a material fact  necessary in order to
         make the statements  made, in light of the  circumstances in which they
         were made,  not  misleading,  or if it shall be  necessary  to amend or
         supplement  the Memorandum to comply with  applicable  law, the Company
         will  forthwith  notify Dallas  Research  thereof and furnish to Dallas
         Research, in such quantities as Dallas Research may reasonably request,
         an amended or supplemental Memorandum which corrects such statements or
         omissions  or causes the  Memorandum  to comply  with  applicable  law.
         Without the prior written consent of Dallas Research,  no copies of the
         Memorandum or any other material  prepared by the Company in connection
         with the Offering  will be given by the Company or its  counsel,  or by
         any  employee,  director or agent of the Company,  to any person in the
         United States except as contemplated by the Dallas Research Agreement.

                  (b)  ADDITIONAL  INFORMATION.  The Company will furnish Dallas
         Research with such other information,  documents and instruments as may
         be required  for an offer made  solely to  accredited  investors  under
         Sections 3(b), 4(2) or 4(6) of the Securities Act and Reg D.

         Dallas  Research's  counsel  with all  information  which such  counsel
         determines to be necessary and otherwise  cooperate  with such counsel,
         to permit such counsel to take all  necessary  action to (i) qualify or
         register  the Special  Warrants for sale under the Blue Sky laws of the
         states of the United States in which Dallas  Research  determines  that
         offers or sales will be made,  or (ii)  obtain an  exemption  from such
         qualification or registration in such states. The Company will promptly
         advise Dallas Research:

                           (A)  Of  any  order,   request  or  suggestion  by  a
                  securities  regulator  of any state for any  amendment  to the
                  Memorandum  or any other filed  materials,  or for  additional
                  information; and

                           (B) Of any action by a  securities  regulator  of any
                  state  suspending the  registration  or  qualification  of the
                  Special Warrants for offer or sale in such state or denying an
                  exemption from such registration or qualification, or of the

                  initiation or threat of any proceeding  for such purpose,  and
                  the Company  will use its best efforts to prevent such action,
                  or if such  action  shall be taken,  to obtain the  withdrawal
                  thereof at the earliest practicable date.

         The Company will provide Dallas  Research any  additional  information,
         documents and instruments which Dallas Research shall deem necessary to
         comply with the rules,  regulations  and  judicial  and  administrative
         interpretations  in those  states and  jurisdictions  where the Special
         Warrants are to be offered for sale or sold. The Company will cooperate
         with  Dallas  Research's  counsel  in filing all  post-Offering  forms,
         documents  or  materials  and  take  all  other  post-Offering  actions
         required  by the Blue  Sky laws of the  states  in  which  the  Special
         Warrants have been offered or sold.

                  (d) USE OF PROCEEDS.  The Company will use its reasonable best
         efforts to use the net  proceeds  of the  Offering  as set forth in the
         Memorandum under the caption "Use of Proceeds."

                  (e) REG D  COMPLIANCE;  PROSPECTUS  UNDERTAKINGS.  The Company
         will comply in all respects with the terms and  conditions of Reg D and
         applicable  Blue Sky laws with  respect to the offering and the sale of
         the Special Warrants only to "accredited  investors" within the meaning
         of Rule 501(a) of Reg. D. The Company  will  perform and fulfill in all
         respects  the  agreements  and  undertakings  made by it in the  Agency
         Agreement and the  Subscription  Agreements  with respect to filing and
         obtaining receipts for a prospectus in Canada.

                  (f)  RESTRICTION ON ISSUANCE OF SECURITIES.  During the period
         commencing on the date hereof and terminating on the Final Closing Date
         the  Company  will not,  without  the prior  written  consent of Dallas
         Research,  issue any securities  other than upon the exercise of rights
         to  acquire  such  securities   exercised  by  holders  of  outstanding
         Convertible  Securities  or Options  of the  Company  described  in the
         Memorandum  and  other  than  stock  options  granted  under  the  Plan
         described  under  the  caption  "Options  to  Purchase  Shares"  in the
         Memorandum.

                  (g)  REGISTRATION  RIGHTS.  The Company will  register  Common
         Shares under the  Securities  Act for the public resale  thereof in the
         United States in accordance  with,  and will be bound by the provisions
         of,  Exhibit  B to this  Agreement  which  is  incorporated  herein  by
         reference.

         7.       ADDITIONAL  REPRESENTATIONS  AND  COVENANTS OF THE COMPANY AND
                  DALLAS RESEARCH.

         7.1. The Company hereby  confirms the  representations,  warranties and

                  (a) The  Company  was on  September  23, 1996 (the date of the
         sale of September Special Warrants under the Canadian Offer) a "foreign
         issuer"  as  defined  in Rule  902(f) of  Regulation  S and  reasonably
         believes  that as of the date  hereof  there is and as of the  dates of
         issuance of the Special  Warrants  and the Common  Shares and  Warrants
         (collectively,  the  "Securities")  there will be no "substantial  U.S.
         market  interest"  (as defined in Rule 902(n) of  Regulation  S) in the
         Securities.

                  (b)  The  Company  is  not  an  open-end  investment  company,
         closed-end  investment  company,  unit investment  trust or face-amount
         certificate  company that is  registered  or required to be  registered
         under the United States Investment Company Act of 1940, as amended.

                  (c)  Neither the  Company  nor any of its  affiliates  nor any
         person  acting on its or their  behalf  (other  than the Agent,  Dallas
         Research and Sunrise,  as to which the Company makes no representation)
         has taken or will take any action  which  would  cause the safe  harbor
         provision  afforded by Rule 903 of Regulation S to be  unavailable  for
         the Canadian Offer or the private offering exemption under Section 4(2)
         of the Securities Act to be unavailable  for the Dallas  Research Offer
         or which would constitute a violation of Rule 10b-6 or Rule 10b-7 under
         the United  States  Securities  Exchange  Act of 1934,  as amended (the
         "Exchange Act") under the Exchange Act.

                  (d) None of the Company,  its  affiliates or any person acting
         on its or their  behalf  (other  than the Agent,  Dallas  Research  and
         Sunrise as to which the Company makes no representation) has offered or
         will  offer to sell  the  Securities  by  means of any form of  general
         solicitation or general  advertising (as those terms are used in Reg D)
         or in any manner  involving  a public  offering  within the  meaning of
         Section 4(2) of the Securities Act.

                  (e)  Neither the  Company  nor its  affiliates  nor any person
         acting on its or their behalf  (other than the Agent,  Dallas  Research
         and  Sunrise  as to which  the  Company  makes no  representation)  has
         offered or will offer any of the Securities  other than pursuant to the
         Canadian Offer, the Dallas Research Agreement and this Agreement or has
         made or will make any "directed  selling efforts" within the meaning of
         Rule 902(b) of  Regulation  S with  respect to the  Securities,  to the
         extent  that any such  action  would  cause the  exemption  afforded by
         Regulation  S to be  unavailable  for offers and sales in the  Canadian
         Offer.

         7.3      Dallas Research represents and agrees to the following:

                  (a) it  will  comply  in  all  respects  with  the  terms  and
         conditions  of Reg D and  applicable  Blue Sky laws with respect to the
         offering  and the  sale of the  Special  Warrants  only to  "accredited
         investors" within the meaning of Rule 501(a) of Reg D.

                  (b) it will not make offers or sales of the  Special  Warrants
         in any  jurisdiction  in  which  the  Special  Warrants  have  not been
         qualified or registered,  or are not exempt from such  qualification or
         registration.

                  (c) it has not and will not  engage in any  "directed  selling
         efforts"  within the meaning of Rule 902(b) of  Regulation  S or in any
         general  solicitation  or  advertising  within the  meaning of Reg D in
         connection with the Dallas Research Offer,  and (e) it has not and will
         not take any action in connection  with the Dallas  Research Offer that
         would  constitute a violation of Rule 10b-6 or 10b-7 under the Exchange
         Act.

                  an  untrue  statement  of a fact  which in  Dallas  Research's
                  opinion  is  material,  or omits to state a fact  which in its
                  opinion is material and is required to be stated therein or is
                  necessary to make the statements therein not misleading;

                           (iii) CERTIFICATE OF CHAIRMAN.  The Company will have

                  and in full force and effect as of such Closing Date;

<PAGE>



                  securities of the Company without the prior written consent of
                  Dallas  Research  at any  time  prior  to the  date  specified
                  therein.

                  (b) CONDITIONS OF THE COMPANY'S  OBLIGATIONS.  The obligations
         of the Company  hereunder  on each  Closing Date will be subject to the
         accuracy  of the  representations  and  warranties  of Dallas  Research
         contained  herein as of the date hereof and as of such Closing Date, to
         the performance by Dallas Research of its obligations  hereunder and to
         the following additional conditions:

                            (i)   ABSENCE  OF   GOVERNMENT   ACTION.   No  order
                  suspending the offer or sale of the Special Warrants will have
                  been  issued  by  the  Commission  or any  other  governmental
                  authority,  and no proceeding  for that purpose will have been
                  initiated or threatened; and

                           (ii) NO MATERIAL MISSTATEMENTS.  The Company will not
                  have  notified  Dallas  Research that any Blue Sky law filing,
                  the Memorandum or any amendment or supplement thereto contains
                  an untrue  statement of a fact which in the Company's  opinion
                  is material,  or omits to state a fact which in its opinion is
                  material and is required to be stated  therein or is necessary
                  to make the statements  therein not  misleading,  in each case
                  only with respect to information  contained therein concerning
                  Dallas Research.

         9. EXPENSES OF SALE. In addition to those items  referred to in Section
4  hereof,  the  Company  will pay or cause to be paid all  costs  and  expenses

connection therewith.

         10.  INDEMNIFICATION AND CONTRIBUTION.

                  (a)  INDEMNIFICATION  BY THE  COMPANY.  The Company  agrees to
         indemnify and hold harmless  Dallas  Research and each person,  if any,
         who controls  Dallas Research within the meaning of the Securities Act,
         against any losses, claims,  damages or liabilities,  joint or several,
         to which Dallas Research or such controlling person may become subject,
         under the Securities Act or otherwise,  insofar as such losses, claims,
         damages or liabilities (or actions in respect  thereof) arise out of or
         are based upon (i) any untrue  statement or alleged untrue statement of
         a material fact contained (A) in the Memorandum, or (B) in any Blue Sky
         law  filing to the  extent  such  statement  was  based on  information
         furnished by the Company,  or (ii) the omission or alleged  omission to
         state in the  Memorandum  or in any Blue Sky law filing a material fact
         required to be



                                                     - 15 -




<PAGE>



         stated therein or necessary in order to make the statements therein, in
         the  light  of the  circumstances  under  which  they  were  made,  not
         misleading;   and  will  reimburse   Dallas   Research  and  each  such
         controlling person for any legal or other expenses  reasonably incurred
         by  Dallas  Research  or such  controlling  person in  connection  with
         investigating or defending any such loss, claim,  damage,  liability or
         action;  provided  that the Company will not be liable in any such case
         to the extent that any such loss, claim, damage or liability arises out
         of or is based upon an untrue  statement or alleged untrue statement or
         omission or alleged  omission  made in the  Memorandum in reliance upon
         and in conformity with written information  furnished to the Company by
         Dallas Research specifically for use in the Memorandum.

                  (b) INDEMNIFICATION BY DALLAS RESEARCH. Dallas Research agrees
         to indemnify and hold harmless the Company and each person, if any, who
         controls the Company  within the meaning of the  Securities Act against
         any losses, claims, damages or liabilities,  joint or several, to which
         the Company or such  controlling  person may become subject,  under the
         Securities Act or otherwise, insofar as such losses, claims, damages or
         liabilities  (or actions in respect  thereof) arise out of or are based
         upon (i) any untrue statement or alleged untrue statement of a material
         fact contained (A) in the Memorandum,  or (B) in any Blue Sky filing to
         the extent such statement  relates solely to Dallas  Research,  or (ii)
         the omission or alleged  omission to state a material  fact required to
         be stated in the  Memorandum  or (to the extent such  omission was of a
         material fact relating  solely to Dallas  Research) in any Blue Sky law
         filing,  or necessary in order to make the statements  therein,  in the
         light of the circumstances  under which they were made, not misleading;
         provided that Dallas  Research will be liable in any such case based on
         the Memorandum only to the extent that such untrue statement or alleged
         untrue  statement or omission or alleged omission in the Memorandum was
         made in  reliance  upon  and in  conformity  with  written  information
         furnished to the Company by Dallas Research specifically for use in the
         Memorandum.

                  (c) PROCEDURE.  Promptly after receipt by an indemnified party
         under this Section 10 of notice of the commencement of any action, such
         indemnified  party  will,  if a claim in respect  thereof is to be made
         against any indemnifying party under this Section 10, notify in writing
         the indemnifying party of the commencement thereof; and the omission so
         to notify the indemnifying  party will (unless the  indemnifying  party
         was  unaware  of such  action  and was  materially  prejudiced  by such
         omission) relieve it from any liability under this Section 10 as to the
         particular item for which indemnification is then being sought, but not
         from any other liability which it may have to any indemnified party. In
         case any such action is brought against any indemnified  party,  and it
         notifies  an  indemnifying  party  of  the  commencement  thereof,  the
         indemnifying party will be entitled to participate  therein, and to the
         extent that it may wish,  jointly  with any other  indemnifying  party,
         similarly  notified,  to assume the defense  thereof,  with counsel who
         shall be to the reasonable  satisfaction of such indemnified party, and
         after notice from the indemnifying  party to such indemnified  party of
         its election so to assume the defense thereof,  the indemnifying  party
         will not be liable to such indemnified  party under this Section 10 for
         any legal or other expenses subsequently incurred by such indemnified



                                                     - 16 -




<PAGE>



         party in  connection  with the defense  thereof  other than  reasonable
         costs of investigation; provided that if, in the reasonable judgment of
         the indemnified  party, it is advisable for the indemnified party to be
         represented by separate  counsel,  the indemnified party shall have the
         right to employ a single counsel in each  jurisdiction to represent the
         indemnified  parties who may be subject to liability arising out of any
         claim in respect of which  indemnity  may be sought by the  indemnified
         parties thereof against the indemnifying party, in which event the fees
         and  expenses  of  such   separate   counsel  shall  be  borne  by  the
         indemnifying  party. Any such indemnifying party shall not be liable to
         any such indemnified party on account of any settlement of any claim or
         action effected without the consent of such indemnifying  party,  which
         consent shall not be unreasonably withheld.

                  (d) CONTRIBUTION.  If the indemnification provided for in this
         Section 10 is  unavailable to any  indemnified  party in respect to any
         losses, claims,  damages,  liabilities or expenses referred to therein,
         then the indemnifying  party, in lieu of indemnifying  such indemnified
         party,   will  contribute  to  the  amount  paid  or  payable  by  such
         indemnified  party,  as a  result  of  such  losses,  claims,  damages,
         liabilities  or expenses (i) in such  proportion as is  appropriate  to
         reflect the relative  benefits received by the Company on the one hand,
         and Dallas  Research on the other hand,  from the Offering,  or (ii) if
         the  allocation  provided  by  clause  (i)  above is not  permitted  by
         applicable  law, in such  proportion as is  appropriate  to reflect not
         only the relative benefits referred to in clause (i) above but also the
         relative fault of the Company on the one hand,  and of Dallas  Research
         on the other hand, in connection with the statements or omissions which
         resulted in such losses,  claims,  damages,  liabilities or expenses as
         well as any  other  relevant  equitable  considerations.  The  relative
         benefits  received by the Company on the one hand, and Dallas  Research
         on the other hand,  shall be deemed to be in the same proportion as the
         total  proceeds  from  the  Dallas  Research  Offer  before   deducting
         expenses)  received by the  Company,  bear to the initial  value of the
         compensation  and to Dallas  Research  pursuant  to Section 4.1 of this
         Agreement.  The  relative  fault of the  Company  on the one hand,  and
         Dallas  Research on the other hand,  will be determined  with reference
         to, among other things,  whether the untrue or alleged untrue statement
         of a material  fact or the omission to state a material fact relates to
         information   supplied  by  the  Company,   and  its  relative  intent,
         knowledge,  access to information and opportunity to correct or prevent
         such  statement or omission.  The amount payable by a party as a result
         of the losses,  claims,  damages,  liabilities or expenses  referred to
         above  will be deemed to include  any legal or other  fees or  expenses
         reasonably  incurred by such party in connection with  investigating or
         defending any action or claim.  The Company and Dallas  Research  agree
         that it would not be just and  equitable  if  contribution  pursuant to
         this Section 10 were  determined by pro rata allocation or by any other
         method of  allocation  which does not take into  account the  equitable
         considerations referred to in this Section 10(d).

         11.   REPRESENTATIONS   AND   COVENANTS   TO  SURVIVE   DELIVERY.   All
representations,  warranties and covenants of the Company and of Dallas Research
herein  will  survive  the  delivery  and  execution  hereof  and  each  Closing
hereunder, and shall remain operative and in full

                             AGENT'S SPECIAL OPTION
                                   for Shares

                                       of

                    HEALTHCARE CAPITAL CORP. (the "Company")
                    (Incorporated under the laws of Alberta)



THIS IS TO CERTIFY  THAT,  of o (the  "Agent")  is the  registered  holder of an
option whereby it is entitled,  without payment of any additional consideration,
to be issued o warrants  (the "Agent's  Warrants")  of HealthCare  Capital Corp.
(the  "Company")  during  the  exercise  period  referred  to below,  subject to
adjustment as provided for herein.  The Agent's  Warrants will entitle the Agent
to purchase up to o common  shares of the Company at a price of $1.25 (U.S.) per
share on or prior to August 31, 1998 unless  cancelled  earlier as  described in
the certificate for the agent's  Warrants.  The Agent's  Warrants will be in the
form attached as Schedule "B".

This Special  Option may be exercised  only at the offices The R-M Trust Company
(the "Transfer Agent"),  at 600 The Dome Tower, 333 - 7th Avenue S.W.,  Calgary,
Alberta,  T2P 2Z1, by completing  the exercise form attached  hereto as Schedule
"A".

The Company has covenanted under the placement agreement between the Company and
the Agent dated as of October 14, 1996 (the "Placement  Agreement")  that, among
other things,  it will use its reasonable best efforts to  expeditiously  obtain
receipts for a final  prospectus  (the "Final  Prospectus")  from the securities
regulatory  authority  of each of  British  Columbia,  Alberta  and  such  other
jurisdictions  as  approved  by the  Agent  and  the  Company  (the  "Qualifying
Jurisdictions"),  for the purposes of qualifying,  under the applicable  laws of
such  provinces,  the  distribution of the Agent's  Warrants,  issuable upon the
exercise of this Special Option. This Special Option will be deemed to have been
exercised by the Agent (without any further action on the part of the Agent), on
the earlier of the fifth  business  day  following  the day (the  "Qualification
Date") on which a receipt is issued for the Final  Prospectus by the last of the
securities   regulatory   authorities   of  the  Provinces  of  the   Qualifying
Jurisdictions and the first anniversary of the date of this Special Option (such
earlier date being herein called the "Deemed Exercise Date").

This Special  Option may be exercised by the Agent during the period  commencing
on the day this Special Option is issued and ending at 5:00 p.m.  (Calgary time)
on the day prior to the Deemed  Exercise  Date.  The Agent may not exercise less
than all of this Special Option.

If this  Special  Option is exercised by the Agent on or before the day prior to
the  Qualification  Date,  the Agent's  Warrants  issued on the  exercise may be
subject to statutory restrictions on


<PAGE>

transfer and the Agent's  Warrants will be endorsed  with a legend  stating that
they may not be traded in Alberta  until the day which is one year from the date
of this Special Option.

On and after the date of any exercise or deemed  exercise of this Special Option
evidenced  by this  Special  Option  Certificate,  the Agent will have no rights
hereunder  except to receive  certificates  representing  the  Agent's  Warrants
registered in the names and amounts directed by the Agent upon surrender of this
Special  Option  to the  Transfer  Agent at its  principal  office  in  Calgary,
Alberta.

The number of common  shares  issuable  upon the exercise or deemed  exercise of
this Special Option shall be adjusted in the events and in the manner following

         (a)      If,  after  November  20, 1996,  the Company  consolidates  or
                  subdivided its shares or pays a stock dividend,  the number of
                  shares to be issued on the  exercise  of the  Agent's  Special
                  Option will be increased or decreased  proportionately so that
                  the Agent's  Special Option will entitle the Agent to the same
                  percentage  of shares  of the  Company  immediately  after the
                  subdivision,  consolidation or stock dividend as the Agent was
                  entitled to immediately before that event occurred.

         (b)      In case of any capital  reorganization or  reclassification of
                  the  capital of the Company or the merger or  amalgamation  of
                  the Company with or into any other company after  November 20,
                  1996,   this   Special   Option   will,   after  the   capital
                  reorganization,   reclassification   of  capital,   merger  or
                  amalgamation,  confer  the  right to  purchase  the  number of
                  shares or other  securities  of the  Company or of the company
                  resulting from the capital  reorganization,  reclassification,
                  merger or  amalgamation,  as the case may be, which would have
                  been issued to the Agent if the Agent had fully exercised this
                  Special Option immediately before the capital  reorganization,
                  reclassification, consolidation, merger or amalgamation and in
                  any such case, if necessary,  appropriate  adjustments will be
                  made in the  application  of the  provisions  of this  Special
                  Option so that rights of the Agent after the event  correspond
                  as nearly as  possible  to the rights of the Agent  before the
                  event.

         (c)      The adjustments provided for herein are cumulative.

On  presentation  at the offices of the  Transfer  Agent as set out above,  this
Special Option may be exchanged for the Agent's Warrants.

This  Special  Option is  non-transferable  other than to members of the Agent's
selling group, as contemplated in the Agency Agreement.

The Holding of this Special  Option does not  constitute the Agent a shareholder
of the Company or entitle it to any right or interest in respect  thereof except
as otherwise provided herein.

Time will be of the essence hereof.

                  Warrant in substitution for the one mutilated, lost, destroyed
                  or stolen, and the substituted Warrant will entitle the Holder
                  to the  same  rights  and  benefits  as the  mutilated,  lost,
                  destroyed or stolen Warrant;

         (b)      the Company will be entitled to require the Holder to provide:

                  (i)      appropriate   evidence  of  ownership  of  the  lost,
                           destroyed or mutilated Warrant;

                  (ii)     proof  of  loss,  destruction  or  mutilation  of the
                           Warrant;

                  (iii)    an indemnity in the amount and form acceptable to the
                           Company; and

                  (iv)     payment  of the  reasonable  costs of the  Company to
                           replace the Warrant.

The exercise price and the number of shares deliverable upon the exercise of the
Warrant are subject to adjustment in the events and in the manner following:

         (a)      If,  after  November  20, 1996,  the Company  consolidates  or
                  subdivides its shares or pays a stock  dividend,  the exercise
                  price and the number of shares to be issued on the exercise of
                  the Warrant will be increased or decreased  proportionately so
                  that the Warrant  will entitle the Holder to purchase the same
                  percentage  of shares of the  Company at the same total  price
                  immediately  after  the  subdivision,  consolidation  or stock
                  dividend as the Holder could purchase  immediately before that
                  event occurred.

         (b)      In case of any capital  reorganization or  reclassification of
                  the  capital of the Company or the merger or  amalgamation  of
                  the Company with or into any other company, after November 20,
                  1996,  each Warrant  will,  after the capital  reorganization,
                  reclassification  of capital,  merger or amalgamation,  confer
                  the right to purchase the number of shares or other securities
                  of the  Company or of the company  resulting  from the capital
                  reorganization,  reclassification,  merger or amalgamation, as
                  the case may be, which would have been issued to the Holder if
                  the Holder had fully exercised the Warrant  immediately before
                  the capital reorganization,  reclassification,  consolidation,
                  merger or


<PAGE>


                                                       - 5 -

                  amalgamation  and in any such case, if necessary,  appropriate
                  adjustments  will be made in the price and the  application of
                  the  provisions  of the  Warrant so that  rights of the Holder
                  after the event correspond as nearly as possible to the rights
                  of the Holder before the event.

         (c)      The   Adjustments   provided  for  in  this   subsection   are
                  cumulative.

4.10     Determination of Adjustments

Any disputes  between the company and any Holder  relating to  adjustments  made
under this section will be finally  determined by the Company's  Auditors or, if
they will not  consent to  determine  the  dispute,  another  firm of  Chartered
Accountants in Calgary, Alberta, appointed by the Company.


5.       COVENANTS BY THE COMPANY

5.1      General Covenants

The Company  will  reserve  and set aside  sufficient  shares in its  authorized
capital  to issue all the  shares  which may be issued  from time to time on the
exercise of the Warrant.


6.       MODIFICATION OF TERMS, MERGER, SUCCESSORS

6.1      Modification of Terms and Conditions for Certain Purposes

The Company may modify these terms and  conditions for any one or more or all of
the following purposes:

         (a)      to add to these terms and conditions any additional  covenants
                  and  enforcement  provisions as, in the opinion of counsel for
                  the  Company,  are  necessary  or advisable to clarify or more
                  fully  articulate  the  terms of the  Warrant,  if  additional
                  covenants  and  enforcement   provisions  do  not  affect  the
                  substantive rights or obligations of the Warrant Holder;

         (b)      to  add  to  or  alter  the  provisions  of  these  terms  and
                  conditions for the  registration,  transfer or exchange of the
                  Warrant  which do not affect the  substance of these terms and
                  conditions;

         (c)      for any other purpose not inconsistent  with the terms hereof,
                  including the correction or  rectification of any ambiguities,
                  defective provisions, errors or omissions herein; and

         (d)      to  evidence  the  succession  of  any   corporation  and  the
                  assumption  by any  successor of the  covenants of the Company
                  under the Warrant.

agrees to be bound by the terms of the Warrant.

6.3      Successor Company Substituted

If the  Company  is  amalgamated  or  otherwise  merged  with or into any  other

         1.       REGISTRATION UNDERTAKINGS.

                  (a) For the purpose of this Exhibit B, the term  "Registerable
Shares"  shall  mean the  Common  Shares of the  Company  issuable  upon (i) the
exercise or deemed exercise of the Special Warrants  (including the Compensation
Warrants) issued in connection with the Dallas Research Offer; (ii) the exercise
of the  Warrants  issued upon the  exercise or deemed  exercise of such  Special
Warrants and (iii) the exercise of the Dallas Research  Warrants issued upon the
exercise of the Dallas Research Option.

                  (b) At any time prior to the fourth  anniversary  of the Final
Closing Date,  the holder or holders (the  "Holders") of at least twenty percent
(20%) of the  Registerable  Shares  (counting  as  Registerable  Shares for this
purpose  securities  referred to in Section 1(a) above that are  exercisable for
Registerable  Shares) may  request,  in writing,  that the Company  register for
resale  under the  Securities  Act not less  than  twenty  percent  (20%) of the
Registerable  Shares. The Company will give prompt written notice (the "Notice")
of such request to each other Holder and will, as promptly as  practicable  (but
in any event within 60 days),  after  receipt of such  request  prepare and file
with the United States Securities and Exchange Commission (the "Commission") (at
the Company's own expense) a  registration  statement  under the  Securities Act
sufficient to permit the public offering of the Registerable Shares specified by
the Holders in the aforementioned  request and such other Registerable Shares as
may be specified by other Holders by written  notice to the Company given within
twenty (20) days after the receipt by them of the Notice.  The Company  will use
its  reasonable  best  efforts to cause such  registration  statement  to become
effective  under the Securities  Act as promptly as practicable  and to maintain
such  effectiveness  so as to permit resale of the  Registerable  Shares covered
thereby  until the  earlier of the time that all such  Registerable  Shares have
been sold and the time that all such Registerable Shares may be sold pursuant to
the  provisions  of Rule 144(k)  under the  Securities  Act;  provided  that the
Company shall only be obligated to file one such  registration  statement  under
this Section 1(b).

                  (c) If at any time from and after the Final  Closing  Date the
Company  proposes to register any of its securities under the Securities Act (on
a form other than Form S-4 or S-8 or their  equivalents),  the Company  will (i)
promptly notify all Holders that such  registration  statement will be filed and
that the  Registerable  Shares  which  are  then  held by such  Holders  will be
included in such registration statement at their request and (ii) subject to the
last sentence of this subsection (c), cause such registration statement to cover
all  Registerable  Shares  which  it has been so  requested  to  include  by the
Holders,  provided  such  request is  delivered to the Company not later than 20
days after  such  notice is given to the  Holders  and  specifies  the number of
Registerable  Shares to be  included  in the  proposed  registration  statement.
Notwithstanding the foregoing provisions, if such registration statement relates
to an  underwritten  offer of Common Shares and the managing  underwriter  shall
inform in writing  the Company and the  Holders  that the  managing  underwriter
believes that the number of shares requested to be included in such registration
statement would materially, adversely affect its



                                                     - 1 -




<PAGE>



ability  to  effect  such  offering,  then  the  Company  will  include  in such
registration  statement  the  number of Common  Shares  which the  Company is so
advised can be sold in (or during the time of) such offering as follows:  First,
all shares proposed by the Company to be sold for its own account,  and, second,
such Registerable Shares requested to be included in such registration, pro rata
by the Holders and other  security  holders  having  registration  rights on the
basis of the number of  Registerable  Shares and other Common Shares so proposed
to be sold by the Holders and by such other security holders and so requested to
be included;  PROVIDED, HOWEVER, that the Company shall be obligated to register
any   Registerable   Shares  and  other  Common  Shares  so  excluded  from  the
registration  statement pursuant to a registration  statement within ninety (90)
days after the  effectiveness  of such  registration  statement  or such greater
number of days as may be specified in "lock-up" agreements entered into with the
managing underwriter.

                  (d)  In  connection  with  any  registration  statement  filed
pursuant to this Section 1 (a "Registration Statement"),  the Company shall take
such action as may be necessary to register or qualify the  Registerable  Shares
registered  thereunder  under the  securities or blue sky laws of such states of
the United States as shall  reasonably be requested by the prospective  sellers,
and shall do any and all other  acts  which may be  necessary  or  advisable  to
permit the proposed sale or other disposition of such Registerable Shares in any
such  state;  provided  that in no event  shall  the  Company  be  obligated  in
connection  therewith to qualify as a foreign  corporation  in any  jurisdiction
where it is not  already  so  qualified,  or to  execute a general  consent  for
service of process in suits  other than those  arising out of the offer and sale
of the  Registerable  Shares,  or to take any action  which would  subject it to
taxation in any jurisdiction where it is not then so subject.

                  (e) The  Company's  obligations  to register and qualify under
this Section 1  Registerable  Shares of any Holder shall be  conditioned in each
instance  upon the timely  receipt by the Company in writing of (1)  information
from such  Holder  as to the  proposed  plan of  distribution  of such  Holder's
Registerable Shares to be included in the Registration  Statement,  and (2) such
other  information  as the Company may  reasonably  require from such Holder for
inclusion in the Registration Statement.

                  (f) All fees,  disbursements and out-of-pocket expenses (other
than any brokerage fees and commissions and legal fees of counsel to any Holder)
in  connection  with the  Registration  Statement  (or seeking or obtaining  the
opinion  of  counsel  to the  Company  under  Section  1(g) and,  if in the sole
discretion  of the  Company  deemed  desirable,  any  no-action  position of the
Commission  with respect to sales pursuant to Rule 144 under the Securities Act)
and in complying with  applicable  state  securities  laws shall be borne by the
Company.  The  Company at its expense  will  supply the Holders of  Registerable
Shares included in the Registration  Statement with copies of such  Registration
Statement and the prospectus  included  therein and in such quantities as may be
reasonably  requested by them. In connection with each  Registration  Statement,
the Company shall furnish to Holders of  Registerable  Shares  included  therein
with such opinions of counsel, comfort letters of accountants,  certificates and
such other documents that are customary in connection with  underwritten  public
offerings and that are reasonably requested by such Holders.




                                                     - 2 -




<PAGE>



                  (g) The Company  shall not be  required  by this  Section 1 to
file any Registration Statement relating to Registerable Shares of any Holder if
the  Company  shall  furnish  such  Holder  with a written  opinion  of  counsel
reasonably  satisfactory  to such Holder to the effect that the proposed  public
offering or other transfer of  Registerable  Shares as to which  registration is
requested is exempt from the registration or  qualification  requirements of all
applicable  federal and state securities laws and would result in all purchasers
or  transferees   thereof   obtaining   securities  which  are  not  "restricted
securities" as defined in Rule 144 under the Securities Act.

                  (h) If, after the date of the  Memorandum,  the Company grants
to any person  registration  rights which are more favorable to such person than
those  afforded to the Holders  under this Section 1, the Holders  shall without
further action be entitled to the benefits of such more favorable rights.

         2.       INDEMNIFICATION.

                  (a) In the event of the filing of any  Registration  Statement
pursuant to Section 1 hereof,  the Company agrees to indemnify and hold harmless
each Holder of  Registerable  Shares  identified  as a selling  security  holder
therein and each person,  if any, who controls such Holder within the meaning of
the Securities Act, against any and all losses,  claims, damages or liabilities,
joint or several (including the costs of any reasonable  investigation and legal
and  other  expenses  incurred  in  connection  with,  and  any  amount  paid in
settlement  of, any action,  suit or proceeding or any claim  asserted) to which
they, or any of them, may become subject under the Securities  Act, the Exchange
Act or other  federal or state law or  regulation,  at common law or  otherwise,
insofar as such losses,  claims,  damages or liabilities  (or actions in respect
thereof)  arise out of or are based upon any untrue  statement or alleged untrue
statement of a material fact contained in such  Registration  Statement,  or any
related  preliminary  prospectus,  final  prospectus,  or  amendment  thereof or
supplement  thereto,  or arise out of or are based upon any  omission or alleged
omission  to state  therein a material  fact  required  to be stated  therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not misleading;  provided, however, that the Company shall
not be liable  under this  Section  2(a) in any such case to the extent that any
such losses,  claims,  damages or  liabilities  arise solely out of or are based
upon an untrue  statement of a material  fact  contained in or any omission of a
material fact from such Registration Statement,  preliminary  prospectus,  final
prospectus or amendment  thereof or supplement  thereto in reliance upon, and in
conformity with,  information furnished in writing to the Company by such Holder
specifically  for  use  therein.  This  indemnity  will  be in  addition  to any
liability which the Company may otherwise have.

                  (b) Each Holder of Registerable  Shares who is identified as a
selling security holder in a Registration  Statement referred to in Section 2(a)
will agree,  severally  and not  jointly,  to  indemnify  and hold  harmless the
Company,  each other person  referred to in subparts (1), (2) and (3) of Section
11(a) of the Securities Act in respect of such Registration Statement,  and each
person,  if any, who controls the Company or any such person  within the meaning
of Section 15 of the Securities Act, against any and all losses, claims, damages
or liabilities  (including costs of any reasonable  investigation  and legal and
other expenses incurred in



                                                     - 3 -




<PAGE>



connection  with,  and any amount paid in  settlement  of, any  action,  suit or
proceeding  or any claim  asserted)  to which they,  or any of them,  may become
subject under the Securities Act, the Exchange Act or other federal or state law
or  regulation,  at common law, or  otherwise,  insofar as such losses,  claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any  untrue  statement  or alleged  untrue  statement  of a  material  fact
contained in such Registration Statement, or any related preliminary prospectus,
final prospectus or amendment thereof or supplement  thereto, or arise out of or
are based upon any omission or alleged omission to state therein a material fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the circumstances  under which they were made, not misleading,  in each
case to the  extent,  but only to the  extent,  that such  untrue  statement  or
omission was made in such Registration Statement,  preliminary prospectus, final
prospectus or amendment  thereof or supplement  thereto in reliance upon, and in
conformity with,  information furnished in writing to the Company by such Holder
specifically  for use therein.  This indemnity  agreement will be in addition to
any liability which a Holder may otherwise have to the Company.

                  (c)  Any  party  that  proposes  to  assert  the  right  to be
indemnified under this Section 2 shall,  promptly after receipt of notice of the
commencement of any action,  suit or proceeding against such party in respect of
which a claim is to be made against an indemnifying  party or parties under this
Section 2,  notify each such  indemnifying  party of the  commencement  thereof,
enclosing  a copy of all  papers  served.  No  indemnification  provided  for in
Section  2(a) or 2(b)  shall be  available  to any party who shall  fail to give
notice as  provided  in this  Section  2(c) if the party to whom  notice was not
given was unaware of the  proceeding to which such notice would have related and
was materially prejudiced by the failure to give such notice but the omission so
to notify such indemnifying  party of any such action,  suit or proceeding shall
not  relieve it from any  liability  that it may have to any  indemnified  party
other  than under this  Section 2 or Section 3 below.  In case any such  action,
suit or proceeding is brought against any indemnified  party and it notifies the
indemnifying party of the commencement  thereof, such indemnifying party will be
entitled to  participate  in, and, to the extent that it may wish,  jointly with
any other indemnifying party similarly  notified,  to assume the defense thereof
with counsel  reasonably  satisfactory  to such  indemnified  party,  and, after
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense thereof and the approval by the indemnified  party of such
counsel (which shall not be unreasonably withheld), the indemnifying party shall
not be liable to such indemnified party for any legal or other expenses,  except
as  provided  below  and  except  for  the  reasonable  costs  of  investigation
subsequently  incurred by such indemnified  party in connection with the defense
thereof. The indemnified party shall have the right to employ its counsel in any
such action,  suit or proceeding but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the employment of counsel
by such  indemnified  party has been  authorized in writing by the  indemnifying
parties,  (ii) the indemnified party shall have reasonably  concluded that there
may be differing or additional  defenses  available to it and not to one or more
of the indemnifying  parties in such action, suit or proceeding so that it would
be  inappropriate  for counsel to represent both the  indemnified  party and the
indemnifying  party in view of actual or  potential  conflicts  of interest  (in
which case if such indemnified party notifies the indemnifying  party in writing
that it elects to employ  separate  counsel at the  expense of the  indemnifying
party, the



                                                     - 4 -

indemnifying  party  shall  not have the  right to assume  the  defense  of such
action,  suit or proceeding on behalf of such indemnified  party);  or (iii) the
indemnifying  parties shall not have  employed  counsel to assume the defense of
such action within a reasonable time after notice of the  commencement  thereof,
in each of which cases the fees and expenses of the indemnified  party's counsel
shall be at the  expense  of the  indemnifying  parties,  it  being  understood,
however,  that the indemnifying party shall not, in connection with any one such
action,  suit or  proceeding  or separate but  substantially  similar or related
actions,  suits or proceedings in the same jurisdiction  arising out of the same
general  allegations or  circumstances,  be liable for the  reasonable  fees and
expenses of more than one separate  firm of attorneys  for the Holders and their
controlling persons,  which firm shall be designated in writing by a majority in
interest of such Holders (based upon the value of the securities included in the
Registration  Statement).  An  indemnifying  party  shall not be liable  for any
settlement of any action, suit, proceeding or claim effected without its written
consent.

         3.   CONTRIBUTION.   In  order  to  provide  for  just  and   equitable
contribution  in  circumstances  in which the  indemnification  provided  for in
Section 2 is due in  accordance  with its terms but for any reason is held to be
unavailable or insufficient to hold harmless an indemnified  party,  the Company
on the one hand and any Holder on the other hand shall,  in lieu of indemnifying
such indemnified party,  contribute to the aggregate losses,  claims, damages or
liabilities referred to in Section 2 above (including costs of any investigation
and legal and other  expenses  reasonably  incurred in connection  with, and any
amount paid in  settlement  of, any  action,  suit or  proceeding  or any claims
asserted),  in such  proportions  as is  appropriate  to  reflect  the  relative
benefits  received  by  the  Company  and  the  Holders  from  any  offering  of
Registerable  Shares and the  relative  fault of the  Company and such Holder in
connection  with the  statements  or  omissions  which  resulted in such losses,
claims,  damages,  liabilities  or  expenses,  as  well  as any  other  relevant
equitable considerations. The relative fault of the Company and any Holder shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or omission related to information  supplied
by the Company (including for this purpose information  supplied by any officer,
director,  employee or agent of the Company) or to written information furnished
to the  Company  by or on  behalf  of such  Holder  specifically  for use in the
preparation of the Registration Statement or any amendment thereof or supplement
thereto, and the parties' relative intent, knowledge,  access to information and
opportunity to correct or prevent such  statement or omission.  It is understood
and agreed that it would not be just and equitable if  contribution  pursuant to
this Section 3 were determined by pro rata allocation  (even if the Holders were
treated as one entity for such  purpose)  or by any other  method of  allocation
which does not take account of the equitable  considerations  referred to above.
Notwithstanding  the  provisions  of this  Section 3 in no case shall any Holder
(except as may be provided by agreement among them) be liable or responsible for
any amount in excess of the  proceeds  received  by such Holder from the sale of
the  Registerable  Shares  included  in the  Registration  Statement,  provided,
however,  that no person  guilty of  fraudulent  misrepresentation  (within  the
meaning  of  Section  11(f)  of  the  Securities   Act)  shall  be  entitled  to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation.  For  purposes of this  Section 3, each  person,  if any, who
controls a Holder  within the  meaning  of Section 15 of the  Securities  Act or
Section 20(a) of the Exchange Act shall have the same rights to  contribution as
such  Holder,  and each person,  if any,  who  controls  the Company  within the
meaning of the



                                                     - 5 -




<PAGE>



Section 15 of the  Securities  Act or Section  20(a) of the Exchange  Act,  each
director of the  Company  and each  officer of the Company who shall have signed
the  Registration  Statement  shall have the same rights to  contribution as the
Company,  subject to the immediately  preceding  sentence of this Section 3. Any
party  entitled  to  contribution  will,  promptly  after  receipt  of notice of
commencement of any action,  suit or proceeding against such party in respect of
which a claim for  contribution  may be made  against  another  party or parties
under this Section 3, notify such party or parties from whom contribution may be
sought,  and  the  omission  so to  notify  such  party  or  parties  from  whom
contribution  may be  sought  shall  relieve  the  party or  parties  from  whom
contribution  may be sought (if such  party was  unaware  of such  action  suit,
proceeding  and was  materially  prejudiced by such omission) from any liability
under  this  Section  3, but not from any other  obligation  it or they may have
hereunder  or other  than under  this  Section  3. No party  shall be liable for
contribution with respect to the settlement of any action,  suit,  proceeding or
claim effected  without its written  consent.  The obligations of the Holders to
contribute  pursuant  to this  Section  3 are  several  in  proportion  to their
respective number of Registerable Shares included in the Registration  Statement
and not joint.

                           OPINION OF COMPANY COUNSEL


         (A) The Company is a corporation  duly organized,  validly existing and
in good  standing  under  the laws of  Alberta,  with full  corporate  power and
authority to own or lease and operate its properties and to conduct its business
as described in the Memorandum.

         (B) The  Company is the direct or indirect  beneficial  owner of all of
the outstanding  securities of each of the corporations (a "Subsidiary")  listed
in  Section  5(b)  of  the  U.S.  Placement  Agreement.  Each  Subsidiary  is  a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation,  with full power and authority,  corporate
and  other,  to own or lease and  operate  its  properties  and to  conduct  its
business  as  currently  conducted,  and is duly  qualified  to do business as a
foreign  corporation  and is in good  standing in all  jurisdictions  where such
qualification is necessary and where failure so to qualify could have a material
adverse  effect on its financial  condition,  results of  operations,  business,
properties  or  prospects.  Except  for the  Subsidiaries,  the  Company  has no
subsidiaries.


         (C) Except as may be required under  applicable  securities laws in the
United States, no authorization, approval, consent, order, registration, license
or permit of any court or governmental  agency or body is required for the valid
authorization,  issuance,  sale and delivery of the Special Warrants, the Common
Shares and Warrants issuable upon exercise of the Special  Warrants,  the Dallas
Research  Option,  the Dallas  Research  Warrants and the Common Shares issuable
upon the exercise of any of the foregoing,  and the  consummation by the Company
of all the transactions contemplated by the Subject Agreements.

         (D) The Company has full power and authority,  corporate and other,  to
execute,  deliver  and  perform the Subject  Agreements  and to  consummate  the
transactions  contemplated  thereby. The execution,  delivery and performance of
the Subject  Agreements by the Company,  the  consummation by the Company of the
transactions  therein  contemplated,  and the compliance by the Company with the
terms of the  Subject  Agreements  have been duly  authorized  by all  necessary
corporate action on the part of the Company.  Each of the Subject Agreements has
been duly executed and delivered by the Company and, assuming due authorization,
execution  and  delivery by the other  parties  thereto,  is a valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms,  except insofar as enforcement  may be limited by applicable  bankruptcy,
insolvency,  reorganization,  moratorium  and other laws affecting the rights of
creditors  generally  and by the  discretion  of  courts in  granting  equitable
remedies,  and except that enforceability of the indemnification  provisions and
the  contribution  provisions set forth in the U.S.  Placement  Agreement may be
limited  by the  securities  laws in the  United  States  or the  public  policy
underlying such laws.

         (E) The execution,  delivery and performance of the Subject  Agreements
by the Company,  the  consummation  by the Company of the  transactions  therein
contemplated, and the





<PAGE>



compliance  by the Company with the terms of the Subject  Agreements do not, and
will not,  with or without  the giving of notice or the lapse of time,  or both,
(1) result in a violation of the constating documents of the Company, (2) result
in a breach of or conflict  with any terms or  provisions  of, or  constitute  a
default under, or result in the modification or termination of, or result in the
creation or imposition of any lien,  security  interest,  charge or  encumbrance
upon any of the properties or assets of the Company  pursuant to, any indenture,
mortgage,  note, contract,  commitment or other agreement or instrument of which
we are aware and to which the  Company is a party or by which the Company or any
of its  properties  or assets are or may be bound or  affected,  (3) violate any
existing applicable law, rule, regulation or, to the best of our knowledge,  any
judgment,  order or decree of any  governmental  agency  or court,  domestic  or
foreign,  having  jurisdiction  over the  Company  or any of its  properties  or
businesses,   or  (4)  have  any   material   adverse   effect  on  any  permit,
certification,  registration,  approval, consent, license or franchise necessary
for the Company to own or lease and operate any of its properties and to conduct
its business or the ability of the Company to make use thereof.

         (F) The Common Shares conform to the description  thereof  contained in
the  Memorandum   under  the  caption   "Description  of  Securities."  All  the
outstanding  Common Shares have been duly  authorized and validly issued and are
fully paid and  nonassessable.  Except as set forth in Section  5(e) to the U.S.
Placement Agreement, there are no outstanding securities convertible into Common
Shares  ("Convertible  Securities") or any options,  warrants or other rights to
purchase  any Common  Shares or  Convertible  Securities  ("Options").  All such
Options constitute the valid and binding obligations of the Company, enforceable
against the  Company in  accordance  with their  respective  terms.  None of the
outstanding Common Shares,  Options or Convertible Securities has been issued in
violation of the preemptive  rights of any  securityholder  of the Company,  and
none of the holders of the  outstanding  Common  Shares,  Options or Convertible
Securities  is subject to  personal  liability  solely by reason of being such a
holder.  The offers and sales of the  outstanding  Common  Shares,  Options  and
Convertible  Securities  were in full  compliance  with all applicable  Canadian
federal  and  provincial  laws.  To  the  best  of  our  knowledge,   after  due
investigation,  except as described in the  Memorandum or as provided in Section
5(e) of the U.S. Placement  Agreement,  no holder of any of the Company's issued
securities  has any rights  ("demand,"  "piggyback"  or  otherwise) to have such
securities registered under the Securities Act.

         (G) The  issuance  and  sale of the  Special  Warrants  (including  the
Compensation  Warrants),  the Warrants, and the Dallas Research Warrants and the
securities   issuable  upon  the  exercise  of  such  warrants  have  been  duly
authorized, and when they are issued as contemplated by the Agreements,  will be
validly issued, and, in the case of Common Shares, fully paid and nonassessable,
and the  holders  thereof  will not be subject to personal  liability  solely by
reason of being such holders.  None of such warrants or other securities will be
subject to preemptive rights of any security-holder of the Company.

         (H) The  certificates  representing  the securities  referred to in (G)
above are in proper legal form.






<PAGE>



         (I)  The  descriptions  in the  Memorandum  of  statutes,  regulations,
government classifications, contracts, instruments and other documents have been
reviewed  by us and,  based  upon such  review,  are  accurate  in all  material
respects and present fairly the information required to be disclosed,  and there
are no material statutes,  regulations or government  classifications or, to the
best of our knowledge, after due investigation, material contracts or documents,
which should be described in the Memorandum  that are not so described.  None of
the material provisions of the contracts or instruments described above violates
any existing applicable law, rule, regulation, or, to the best of our knowledge,
any  judgment,  order or  decree  of any  governmental  agency  or court  having
jurisdiction over the Company or any of its assets or businesses. To the best of
our  knowledge,  the Company is not in default  under any  contract or agreement
material  to its  business  or under any  promissory  note or other  evidence of
indebtedness for borrowed funds.

         (J) Upon delivery of the Special  Warrants  (including the Compensation
Warrants)  and the Dallas  Research  Warrants as provided in the U.S.  Placement
Agreement,  the persons  acquiring the same will acquire good title thereto free
and clear of all liens, encumbrances,  equities,  security interests and claims,
other then such liens,  encumbrances,  equities,  security  interests  or claims
placed on the securities by such persons.

         (K) To the best of our knowledge, after due investigation,  the Company
is not in violation  of, or in default  under,  any term or provision of (i) its
constating  documents,  (ii) any indenture,  mortgage,  contract,  commitment or
other  agreement or  instrument  to which it is a party or by which it or any of
its properties or business is or may be bound or subject,  or (iii) any existing
applicable law, rule, regulation,  judgment, order or decree of any governmental
agency or court, Canadian or otherwise,  having jurisdiction over the Company or
any Subsidiary or any of their respective properties or businesses.  The Company
owns,  possesses or has obtained all governmental  and other licenses,  permits,
certifications,  registrations,  approvals or consents and other  authorizations
necessary to own or lease, as the case may be, and to operate its properties and
to conduct its business as currently  conducted and described in the Memorandum,
and  all  such  licenses,  permits,  certifications,  registrations,  approvals,
consents and other  authorizations are outstanding and in good standing.  To the
best of our knowledge, after due investigation, there are no proceedings pending
or threatened,  nor is there any basis therefor, seeking to cancel, terminate or
limit  such  licenses,  permits,  certifications,  registrations,  approvals  or
consents or authorizations.

         (L) To the best of our knowledge, after due investigation, there are no
claims, actions, suits, proceedings,  arbitrations,  investigations or inquiries
before any governmental  agency,  court or tribunal,  Canadian or otherwise,  or
before any  private  arbitration  tribunal,  pending or  threatened  against the
Company,  or  involving  the  properties  or business of the Company  which,  if
determined  adversely to the Company,  would,  individually or in the aggregate,
result in any material adverse change in the financial  position,  shareholders'
equity, results of operations,  properties,  business,  management or affairs of
the Company,  or which relate in any way to the validity of the capital stock of
the Company or the  validity of the U.S.  Placement  Agreement  or of any action
taken or to be taken by the Company pursuant to, or in connection with, the U.S.
Placement Agreement.





<PAGE>




         (M) The  Company  and the  Subsidiaries  own or  possess  adequate  and
enforceable rights to use all patents, patent applications,  trademarks, service
marks,  copyrights,  trade  secrets,  confidential  information,  processes  and
formulations  used or  proposed  to be used in the  conduct of their  businesses
currently  conducted  and  described  in  the  Memorandum   (collectively,   the
"Intangibles").  To the best of our knowledge, after due investigation,  neither
the Company nor any Subsidiary has infringed  upon, and is not infringing  upon,
the rights of others with  respect to the  Intangibles,  and we are not aware of
any licenses with respect to the  Intangibles  which are required to be obtained
by the Company; and, to the best of our knowledge,  no other party has infringed
or is infringing upon the Intangibles.

                  While we have not made any independent  investigation  of, are
not  passing  upon,  and do not  assume  responsibility  for,  the  accuracy  or
completeness  of the  statements  contained  in the  Memorandum  (other  than as
indicated  in  paragraph  (F) of this  opinion),  on the  basis  of  discussions
regarding the business and affairs of the Company and our familiarity  with such
business  and affairs as a result of having  served as counsel for the  Company,
nothing  has  come to our  attention  that  would  lead us to  believe  that the
Memorandum  (other than the financial  statements and notes and other  financial
and statistical data included therein,  as to which we express no view) contains
an  untrue  statement  of a  material  fact or omits to  state a  material  fact
required to be stated  therein or necessary to make the  statements  therein not
misleading.

                                                     October 14, 1996


Sunrise Securities Corporation
135 East 57th Street, 11th Floor
New York, New York 10022

Ladies and Gentlemen:

         HealthCare  Capital  Corp.,  an Alberta  corporation  (the  "Company"),
hereby confirms its agreement with you ("Sunrise") as follows:

         1.  DESCRIPTION  OF  TRANSACTION.  The  Company  is in the  process  of
offering  and selling in a private  offering  (the  "Offering")  up to 4,810,000
special  warrants in the capital of the Company (the  "Special  Warrants")  at a
price of U.S.  $1.25  per  Special  Warrant  for  gross  proceeds  of up to U.S.
$6,012,500 and, in an Agency Agreement (the "Agency Agreement") dated August 22,
1996 between it and C.M.  Oliver & Company  Limited (the "Agent")  appointed the
Agent as the  Company's  project  manager for the Offering and as its  exclusive
agent in Canada,  on a best efforts basis,  to solicit  subscriptions  under the
Offering  from persons  resident in certain  provinces of Canada (the  "Canadian
Offer").  The Canadian Offer was completed,  with the sale thereunder of 810,000
Special  Warrants,  on September  23, 1996.  Each Special  Warrant  entitles the
holder thereof to receive, without the payment of any additional  consideration,
one common share in the capital of the Company (a "Common  Share") and one share
purchase warrant (a "Warrant")  entitling the holder thereof to purchase,  until
August 31, 1998, one Common Share at a price of U.S. $2.00.

         2.  APPOINTMENT OF SUNRISE.  The Company hereby appoints Sunrise as its
co-agent to solicit subscriptions in the United States, on a best efforts basis,
for up to 2,000,000  Special  Warrants  constituting a part of the Offering (the
"Sunrise  Offer").  (Dallas Research & Trading Inc.  ("Dallas  Research") may as
co-agent solicit  subscriptions for an additional  2,000,000 Special  Warrants).
Sunrise,  on  the  basis  of  the  representations,  warranties,  covenants  and
agreements of the Company herein, and subject to the conditions herein,  accepts
such  appointment  and agrees,  in  connection  with the  Offering  that it will
endeavor to obtain, on a best efforts basis, subscribers ("Subscribers") for the
Special  Warrants  offered  as part of the  Sunrise  Offer.  By  executing  this
Agreement, the Agent: (a) consents to the execution, delivery and



                                                     - 1 -

<PAGE>



performance by the Company and Sunrise of this  Agreement;  (b) makes for itself
the  representations  and agreements made by the Company in Sections 7.2(c), (d)
and  (e)  of  this  Agreement  (deleting  for  this  purpose  the  parenthetical
exclusions contained therein); and (c) confirms the representations,  warranties
and  covenants  made by it in Schedule A to the Agency  Agreement as of the date
made and as of the date hereof.

         3.  PURCHASE,  SALE AND  DELIVERY  OF UNITS.  Subject  to the terms and
conditions set forth herein, the Company and Sunrise agree as follows:

                  (a)  REGULATION D OFFERING.  Neither the offer nor the sale of
         the Special  Warrants  has been or will be  registered  with the United
         States Securities and Exchange  Commission (the "Commission") under the
         United  States  Securities  Act of 1933,  as amended  (the  "Securities
         Act").  The Special  Warrants  will be offered and sold pursuant to the
         Sunrise Offer in reliance upon and in  compliance  with the  exemptions
         from  registration  provided  by  Sections  3(b),  4(2) and 4(6) of the
         Securities Act and  Regulation D thereunder  ("Reg D") and will only be
         sold to  "accredited  investors" as such term is defined in Reg D. Such
         Special Warrants will be offered for sale only in those states in which
         the Special  Warrants  shall have been qualified or registered for sale
         or are exempt from such qualification or registration. The Company will
         provide Sunrise,  for delivery to all offerees and purchasers and their
         representatives,  copies of the  United  States  Confidential  Offering
         Memorandum dated October 16, 1996 of the Company (the "Memorandum") and
         such other  information,  documents and instruments which Sunrise deems
         necessary to comply with the statutes,  rules, regulations and judicial
         and administrative interpretations applicable to the Sunrise Offer.

                  (b)  SUBSCRIPTION  FOR SPECIAL  WARRANTS.  Purchase of Special
         Warrants  shall occur by execution  and delivery by a Subscriber of two
         copies  of  a  Subscription  Agreement  in  the  form  annexed  to  the
         Memorandum  (the  "Subscription  Agreement"),  together with such other
         documents  and  instruments  as  the  Company  or  Sunrise  shall  deem
         appropriate.

                  (c) SEGREGATION OF FUNDS. Each Subscriber shall tender a check
         or money order payable to "Sunrise Securities Corporation, as agent for
         HealthCare Capital Corp.," or wire transfer funds to the Escrow Account
         (defined  below),  in payment of the full purchase price of the Special
         Warrants  subscribed  for.  The  proceeds of such checks and such funds
         shall be held in an escrow  account  (the  "Escrow  Account") at United
         States Trust Company of New York (the "Bank"). Fees charged by the Bank
         in connection  with the Escrow Account shall be paid by the Company and
         the  Company  shall be entitled  to any  interest  earned in the Escrow
         Account.

                  (d)  CLOSING;  TERMINATION  OF  OFFERING.  The  Closing of the
         Sunrise Offer (the "Final Closing") shall occur on November 15, 1996 or
         such later  date as may be  mutually  agreed  upon by the  Company  and
         Sunrise (the "Final Closing Date").  By mutual agreement of the Company
         and Sunrise,  an interim closing (the "Initial Closing") of the Sunrise
         Offer may occur prior to the Final Closing Date. Each of the Initial

         Closing and the Final  Closing is referred to herein as a "Closing" and
         the date on which  each  occurs is  referred  to  herein as a  "Closing
         Date". At each Closing, the Company shall deliver to Sunrise, on behalf
         of the  appropriate  Subscribers,  the  certificates  representing  the
         Special  Warrants being  purchased by such  Subscribers at such Closing
         against payment  therefor out of the Escrow Account.  In the event that
         no Special  Warrants are sold hereunder,  on the Final Closing Date all
         terms of this Agreement shall be  automatically  terminated and neither
         party shall have any further  obligation  to the other party under this
         Agreement  other than the  Company's  obligation to pay expenses as set
         forth in Section 4.3 and Section 9 of this Agreement.

         4.       COMPENSATION OF SUNRISE.

         4.1. At each  Closing,  the Company  shall pay Sunrise (or,  subject to
applicable  securities  laws, its designee),  as  compensation  for its services
rendered under this Agreement, the following:

                  (a) A selling  commission  equal to 9% of the  gross  proceeds
         from the sale of Special  Warrants  at such  Closing,  payable,  at the
         option of Sunrise,  in cash or in Special  Warrants (the  "Compensation
         Warrants")  valued for this purpose at U.S. $1.25 per Special  Warrant;
         and

                  (b) A  special  option in the form of  Exhibit  A hereto  (the
         "Sunrise  Option")  entitling Sunrise to acquire without the payment of
         any consideration  warrants (the "Sunrise Warrants") to purchase, at an
         exercise price of U.S. $1.25 per share, Common Shares in a number equal
         to 10% of the number of Special Warrants sold at such Closing.

In addition,  at each Closing the Company shall,  to the extent not  theretofore
paid,  pay to Sunrise a  non-refundable  consulting fee equal to 1% of the gross
proceeds  from the sale of Special  Warrants in the Sunrise Offer (not to exceed
U.S.  $25,000) for financial  advisory services to be rendered by Sunrise to the
Company.

         4.2. The  Compensation  Warrants,  the Sunrise  Option,  the securities
issuable  upon the exercise or deemed  exercise of each,  and the Common  Shares
issuable upon exercise of the Sunrise Warrants and of the Warrants acquired upon
the  exercise  or  deemed  exercise  of the  Compensation  Warrants  will all be
"restricted  securities" within the meaning of Rule 144 under the Securities Act
and the certificates  therefor (and any certificates issued in exchange therefor
or replacement thereof) shall bear an appropriate  restrictive legend reflecting
applicable restrictions on transfer.

         4.3. In addition to the  compensation  payable to Sunrise under Section
4.1 of this  Agreement,  the Company shall,  at each Closing,  pay, or reimburse
Sunrise for, the previously unpaid  reasonable fees,  disbursements and costs of
Carter,  Ledyard & Milburn,  legal counsel to Sunrise,  in connection  with this
Agreement and the transactions contemplated hereby and in

         5.   REPRESENTATIONS  AND  WARRANTIES  OF  THE  COMPANY.   The  Company
represents and warrants to Sunrise as follows:

                  (a) OFFERING MEMORANDUM. The Memorandum, as of its date and as
         of the date of this Agreement does not, and at all subsequent  times up
         to and including  the Final  Closing Date will not,  contain any untrue
         statement  of a  material  fact,  or omit to state  any  material  fact
         required  to be stated  therein  or  necessary  to make the  statements
         therein,  in light of the  circumstances  in which they were made,  not

                  (b) ORGANIZATION; GOOD STANDING;  SUBSIDIARIES. The Company is
         a corporation  duly  organized,  validly  existing and in good standing
         under the laws of Alberta, with full power and authority, corporate and

         business as currently  conducted.  The Company is duly  qualified to do
         business as a foreign corporation and is in good standing in the States
         of  Oregon  and  Washington,  the  only  jurisdictions  in  which  such
         qualification is necessary and where failure so to qualify could have a
         material  adverse  effect  on  the  financial  condition,   results  of
         operations,  business,  properties  or prospects of the Company and its
         Subsidiaries  taken as a whole.  The  Company is the direct or indirect
         beneficial owner of all of the outstanding  securities of the following

         "Subsidiaries"):

                  HC  HealthCare   Hearing  Clinics  Ltd.,  a  British  Columbia
                  corporation;

         in good standing under the laws of its  jurisdiction of  incorporation,
         with full power and authority, corporate and other, to own or lease and
         operate  its  properties  and to  conduct  its  business  as  currently
         conducted,   and  is  duly  qualified  to  do  business  as  a  foreign
         corporation  and is in good  standing in all  jurisdictions  where such
         qualification is necessary and where failure so to qualify could have a
         material  adverse  effect  on  its  financial  condition,   results  of
         operations,   business,   properties  or  prospects.   Except  for  the
         Subsidiaries, the Company has no subsidiaries.

                  (c)  GOVERNMENTAL  AUTHORITY.  Except as may be required under
         applicable  state  securities  laws in the  United  States  ("Blue  Sky
         laws"), no authorization, approval,

         consent,  order,  registration,  license  or  permit  of any  court  or
         governmental  agency or body, is required for the valid  authorization,
         issuance,  sale and delivery of the Special  Warrants,  the  securities
         issuable upon the exercise or deemed  exercise of the Special  Warrants
         and upon the  exercise  of the  Warrants  issued  upon the  exercise or
         deemed exercise, and the securities referred to in Section 4.2, and the
         consummation  by the Company of all the  transactions  contemplated  by
         this Agreement,  the Subscription  Agreements,  the Sunrise Option, the
         Sunrise Warrants,  the indenture dated as of September 17, 1996 between
         the Company and The R-M Trust Company  relating to the Special Warrants
         (the  "Special  Warrant  Indenture")  and  the  indenture  dated  as of
         September  17,  1996  between  the  Company  and The R-M Trust  Company
         relating to the Warrants (the "Warrant Indenture")  (collectively,  the
         "Subject Agreements").

                  (d)  AUTHORIZATION  OF AGREEMENTS.  The Company has full power
         and authority, corporate and other, to execute, deliver and perform the
         Subject  Agreements  and to consummate  the  transactions  contemplated
         thereby.  The  execution,  delivery  and  performance  of  the  Subject
         Agreements  by the  Company,  the  consummation  by the  Company of the
         transactions  therein  contemplated,  and the compliance by the Company
         with the terms of the Subject  Agreements  have been duly authorized by
         all  necessary  corporate  action  on the  part  of the  Company.  This
         Agreement,  the Special  Warrant  Indenture and Warrant  Indenture have
         been,  and the  Subscription  Agreement and the Sunrise Option will be,
         duly executed and delivered by the Company and are or will be the valid
         and binding  obligations of the Company enforceable against the Company
         in  accordance  with  their   respective   terms,   except  insofar  as
         enforcement  may  be  limited  by  applicable  bankruptcy,  insolvency,
         reorganization,  moratorium  and other  laws  affecting  the  rights of
         creditors  generally  and by  the  discretion  of  courts  in  granting
         equitable   remedies,   and   except   that   enforceability   of   the
         indemnification provisions and the contribution provisions set forth in
         this  Agreement  may be limited by the federal  securities  laws of the
         United States or state securities laws or the public policy  underlying
         such laws.  The  execution,  delivery  and  performance  of the Subject
         Agreements  by the  Company,  the  consummation  by the  Company of the
         transactions  therein  contemplated,  and the compliance by the Company
         with the terms of the Subject  Agreements do not, and will not, with or
         without the giving of notice or the lapse of time, or both,  (i) result
         in any violation of the  constating  documents of the Company or any of
         its  Subsidiaries,  (ii) result in a breach of or conflict  with any of
         the terms or provisions of, or constitute a default under, or result in
         the  modification  or  termination  of, or result  in the  creation  or
         imposition of any lien,  security interest,  charge or encumbrance upon
         any  of  the  properties  or  assets  of  the  Company  or  any  of its
         Subsidiaries  pursuant to, any  indenture,  mortgage,  note,  contract,
         commitment or other agreement or instrument to which the Company or any
         Subsidiary is a party or by which the Company or any  Subsidiary or any
         of its or their  properties  or assets are or may be bound or affected;
         (iii) violate any existing applicable law, rule, regulation,  judgment,
         order or  decree of any  governmental  agency  or  court,  domestic  or
         foreign,  having jurisdiction over the Company or any Subsidiary or its
         or their  properties  or business;  or (iv) have any  material  adverse
         effect on any permit, certification,  registration,  approval, consent,
         license or franchise necessary for the Company or any Subsidiary to own
         or lease and operate any of its

         properties and to conduct its business or the ability of the Company or
         such Subsidiary to make use thereof.

                  (e) CAPITALIZATION.  The Company had, at July 31, 1996, a duly
         authorized  and  outstanding   capitalization   as  set  forth  in  the
         Memorandum under the caption  "Capitalization,"  and the Common Shares,
         special  warrants and warrants  described  in the  description  thereof
         contained in the  Memorandum  under the caption  "Description  of Share
         Capital" conform to such description. All the outstanding Common Shares
         have been duly  authorized  and  validly  issued and are fully paid and
         nonassessable.  Except as set  forth in the  Memorandum  and  except as
         contemplated  by the  Offering,  there are,  and until the Closing Date
         there will be, no outstanding securities convertible into Common Shares
         ("Convertible  Securities") or any options, warrants or other rights to
         purchase any Common Shares or Convertible Securities  ("Options").  All
         such outstanding  Options constitute the valid and binding  obligations
         of the  Company,  enforceable  against the Company in  accordance  with
         their respective terms. None of the outstanding Common Shares,  Options
         or  Convertible  Securities  have  been  issued  in  violation  of  any
         preemptive or similar right of any  securityholder of the Company,  and
         none of the  holders  of the  outstanding  Common  Shares,  Options  or
         Convertible  Securities  is subject  to  personal  liability  solely by
         reason of being such a holder.  The offers and sales of the outstanding
         Common Shares,  Options and Convertible Securities were at all relevant
         times exempt from  registration or  qualification  under the Securities
         Act and any applicable  Blue Sky Laws and were in full  compliance with
         all applicable  Canadian federal and provincial laws and stock exchange
         regulations.  Except as  provided  in  Exhibit B hereto  and except for
         registration  rights granted in connection  with the acquisition by the
         Company of Hearing Care  Associates and proposed to be granted,  in the
         "SONUS"  acquisition  described in the Memorandum,  no holder of any of
         the Company's issued securities has any rights  ("demand,"  "piggyback"
         or otherwise) to have such securities  registered  under the Securities
         Act.

                  (f)  AUTHORIZATION  OF SHARES AND  WARRANTS.  The issuance and
         sale of the Special Warrants (including the Compensation Warrants), the
         Sunrise Option and the securities  issuable upon the exercise of any of
         the  foregoing  and of the Warrants and the Sunrise  Warrants have been
         duly  authorized,  and when issued as contemplated by the indentures or
         agreements relevant thereto,  will be validly issued and fully paid and
         nonassessable,  and the holders thereof will not be subject to personal
         liability  solely  by  reason  of  being  such  holders.  None  of such
         securities  is  or  will  be  subject  to  preemptive   rights  of  any
         securityholder of the Company.

                  (g)  NO   ANTI-DILUTION   ADJUSTMENT.   The  issuance  of  the
         securities  of the  Company  contemplated  by this  Agreement  will not
         result  in any  adjustment  in the  number  of  Common  Shares,  or the
         exercise price or conversion  ratio per Common Share,  under any of the
         Company's outstanding Options or Convertible Securities.

                  (h)  NONCONTRAVENTION.  Neither  the  Company  nor  any of its
         Subsidiaries  is in  violation  of, or in  default  under,  any term or
         provision of (i) its constating documents,



                                                     - 6 -

         (ii) any indenture,  mortgage, contract,  commitment or other agreement
         or  instrument  to  which  it is a party  or by  which it or any of its
         properties  or  business  is or may be bound or  subject,  or (iii) any
         existing applicable law, rule, regulation, judgment, order or decree of
         any  governmental  agency  or  court,  Canadian  or  otherwise,  having
         jurisdiction  over  the  Company  or the  Subsidiary  or  any of  their
         respective  properties or businesses.  The Company and each  Subsidiary
         owns,  possesses or has obtained all  governmental  and other licenses,
         permits, certifications, registrations, approvals or consents and other
         authorizations  necessary  to own or lease,  as the case may be, and to
         operate  its  properties  and to  conduct  its  business  as  currently
         conducted  and  described  in the  Memorandum,  and all such  licenses,
         permits, certifications,  registrations,  approvals, consents and other
         authorizations are in good standing.  There are no proceedings  pending
         or, to the best of the Company's  knowledge,  threatened,  nor is there
         any basis  therefor,  seeking  to cancel,  terminate  or limit any such
         licenses, permits, certifications, registrations, approvals or consents
         or authorizations.

                  (i) LITIGATION.  Except as set forth in the Memorandum,  there
         are   no   claims,   actions,   suits,    proceedings,    arbitrations,
         investigations  or inquiries before any governmental  agency,  court or
         tribunal,  Canadian or  otherwise,  or before any  private  arbitration
         tribunal,   pending  or,  to  the  best  of  the  Company's  knowledge,
         threatened  against  the Company or any  Subsidiary  or  involving  the
         properties  or  business  of the Company or any  Subsidiary  which,  if
         determined adversely,  would, individually or in the aggregate,  result
         in any material adverse change in the financial position, shareholders'
         equity,  results of  operations,  properties,  business,  management or
         affairs of the Company and the Subsidiaries  taken as a whole, or which
         relate in any way to the  validity of the capital  stock of the Company
         or the  validity  of this  Agreement,  or of any action  taken or to be
         taken by the Company pursuant to, or in connection with this Agreement,
         nor, to the best of the Company's knowledge, is there any basis for any
         such claim, action,  suit,  proceeding,  arbitration,  investigation or
         inquiry.  There are no outstanding orders,  judgments or decrees of any
         court,  governmental  agency or other tribunal  specifically naming the
         Company or any  Subsidiary  and enjoining the Company or any Subsidiary
         from taking,  or requiring the Company or any  Subsidiary to take,  any
         action,  or to which  the  Company  or any  Subsidiary  or its or their
         properties or business is bound or subject.

                  (j)  FINANCIAL  STATEMENTS.  Shikaze  Ralston,  the  chartered
         accountants  who have  rendered a report with respect to the  financial
         statements   included  in  the  Memorandum,   are  "independent  public
         accountants"   within  the  meaning  of  the  Securities  Act  and  the
         regulations   promulgated  under  the  Securities  Act.  The  financial
         statements  and notes thereto  included in the  Memorandum are complete
         and correct and present fairly the financial position of the Company as
         of the dates  thereof,  and the  results of  operations  and changes in
         financial  position of the Company for the periods  indicated  therein,
         all in conformity  with  generally  accepted  accounting  principles in
         Canada applied on a consistent basis throughout the periods involved.

                  (k)  LIABILITIES.  Except as and to the  extent  reflected  or
         reserved against in the financial statements of the Company included in
         the Memorandum, the Company as at



                                                     - 7 -

<PAGE>



         July 31,  1996,  had no material  liabilities,  debts,  obligations  or
         claims asserted  against it, whether accrued,  absolute,  contingent or
         otherwise, and whether due or to become due, including, but not limited
         to,  liabilities  on account of taxes,  other  governmental  charges or
         lawsuits brought subsequent to such date.

                  (l) TAXES.  The Company and each  Subsidiary has filed all tax
         returns required to be filed with the appropriate taxing authorities in
         Canada  and  the  United  States,  including  all  provincial,   state,
         municipal  and other  local  authorities  (whether  relating to income,
         sales, franchise, withholding, real or personal property or other types
         of  taxes)  or has duly  obtained  extensions  of time  for the  filing
         thereof,  and has paid in full all taxes which have become due pursuant
         to such  returns or claimed to be due by any such taxing  authority  or
         otherwise due and owing;  and the  provisions for income taxes payable,
         if any, shown on the consolidated financial statements contained in the
         Memorandum are sufficient for all accrued and unpaid taxes,  whether or
         not  disputed,  and for all periods to and  including the dates of such
         consolidated  financial statements.  Each of the tax returns heretofore
         filed by the  Company  and each  Subsidiary  correctly  and  accurately
         reflects the amount of its tax  liability  thereunder.  The Company and
         each  Subsidiary  has  withheld,  collected  and paid all other levies,
         assessments,  license fees and taxes to the extent  required  and, with
         respect to  payments,  to the extent  that the same have become due and
         payable. Except as disclosed in writing to Sunrise, neither the Company
         nor any  Subsidiary  has  executed or filed with any taxing  authority,
         United States, Canada or otherwise,  any agreement extending the period
         for  assessment or collection of any income taxes and is not a party to
         any  pending   action  or   proceeding   by  any  foreign  or  domestic
         governmental  agency for  assessment  or  collection  of taxes,  and no
         claims for assessment or collection of taxes have been asserted against
         the Company.

                  (m)  CONDUCT OF  BUSINESS.  Since the  respective  dates as of
         which  information is given in the Memorandum,  neither the Company nor
         any  Subsidiary has (i) canceled,  without  payment in full, any notes,
         loans or other obligations  receivable or other debts or claims held by
         it other than in the ordinary course of business;  (ii) sold, assigned,
         transferred,  abandoned, mortgaged, pledged or subjected to lien any of
         its properties,  tangible or intangible,  or rights under any contract,
         permit, license, franchise or other agreement other than sales or other
         dispositions of goods or services in the ordinary course of business at
         customary terms and prices; (iii) increased the compensation payable to
         any of its officers,  directors or other employees (including salaries,
         fringe  benefits,  pensions,  profit  participations  and  payments  or
         benefits of any kind whatsoever but excluding an increase of US $20,000
         in the base annual salary of the Vice-President  Finance); (iv) entered
         into any line of business  other than that conducted by it on such date
         or  entered  into any  transaction  not in the  ordinary  course of its
         business;  (v)  conducted  any line of business in any manner except by
         transactions customary in the operation of its business as conducted on
         such date; or (vi) declared,  made or paid or set aside for payment any
         cash or non-cash distribution on any shares of its capital stock.

                  (n)  PROPERTIES.  The Company and each Subsidiary has good and
         marketable title in fee simple to all real property,  and good title to
         all personal property (tangible



                                                     - 8 -

         and intangible), owned by it, free and clear of all security interests,
         charges, mortgages, liens, encumbrances and defects, except such as are
         described in the  Memorandum  or such as do not  materially  affect the
         value or transferability of such property and do not interfere with the
         use of such property made or proposed to be made by the Company or such
         Subsidiary.  The leases,  licenses or other  contracts  or  instruments
         under  which  the  Company  and  each  Subsidiary  leases,  holds or is
         entitled to use any property,  real or personal, are valid,  subsisting
         and  enforceable  only with such  exceptions as are not material and do
         not  interfere  with the use of such  property  made, or proposed to be
         made, by the Company or such Subsidiary,  and all rentals, royalties or
         other payments  accruing  thereunder which became due prior to the date
         of this  Agreement have been duly paid, and neither the Company nor any
         Subsidiary is in default  thereunder  and, to the best of the Company's
         knowledge, no event has occurred which, with the passage of time or the
         giving of  notice,  or both,  would  constitute  a default  thereunder.
         Neither the  Company  nor any  Subsidiary  has  received  notice of any
         violation  of any  applicable  law,  ordinance,  regulation,  order  or
         requirement relating to its owned or leased properties.

                  (o) INSURANCE.  The Company and each Subsidiary has adequately
         insured its properties against loss or damage by fire or other casualty
         and maintains, in adequate amounts, such other insurance, including but
         not  limited  to,  liability  insurance,  as is usually  maintained  by
         prudent companies engaged in the same or similar businesses.

                  (p)  CONTRACTS.  Each  contract or other  instrument  (however
         characterized or described) to which the Company or any Subsidiary is a
         party,  or to which the  Company's or any  Subsidiary's  properties  or
         businesses are or may be subject,  has been duly and validly  executed,
         is in full force and effect in all material respects and is enforceable
         against the parties thereto in accordance  with its terms,  and none of
         such  contracts or  instruments  has been  assigned by the Company or a
         Subsidiary.  Neither the Company nor the Subsidiary nor, to the best of
         the Company's knowledge, any other party to such contract or instrument
         is in default  thereunder and, to the best of the Company's  knowledge,
         no event has  occurred  which,  with the lapse of time or the giving of
         notice,  or both,  would constitute a default  thereunder.  None of the
         material  provisions  of such  contracts  or  instruments  violates any
         existing applicable law, rule, regulation, judgment, order or decree of
         any governmental  agency or court having  jurisdiction over the Company
         or  any  Subsidiary  or  any of its  or  such  Subsidiary's  assets  or
         businesses.

                  (q) EMPLOYMENT AGREEMENTS. The employment agreements described
         in the  Memorandum  under the  caption  "Management  and  Directors  --
         Employment and Consulting  Agreements" are valid and binding agreements
         enforceable  against  the  Company  and the  respective  other  parties
         thereto  in  accordance  with  their  terms,  except  insofar  as  such
         enforceability  may be limited by  applicable  bankruptcy,  insolvency,
         moratorium or other similar laws or arrangements  affecting  creditors'
         rights generally and subject to principles of equity.

                  (r) BENEFIT PLANS.  Except for the Incentive Stock Option Plan
         described  in the  Memorandum  under the  caption  "Options to Purchase
         Shares," the Company has no



                                                     - 9 -

<PAGE>



         employee benefit plans (including,  without limitation,  profit sharing
         and welfare benefit plans) or deferred compensation arrangements.

                  (s)  CONTRIBUTIONS.  Neither the  Company nor any  Subsidiary,
         directly or indirectly,  at any time (i) made any  contributions to any
         candidate for political  office,  or failed to disclose  fully any such
         contribution  in  violation  of law,  or (ii) made any  payment  to any
         governmental  officer or official,  or other person charged with public
         or quasi-public duties,  other than payments or contributions  required
         or allowed by applicable law.
                  (t)  REG  D  QUALIFICATION.  Subject  to  the  warranties  and
         covenants  of Sunrise in Section 7.2 of this  Agreement,  the offer and
         sale of the Special  Warrants by the Company have satisfied and on each
         Closing Date will have satisfied,  all of the  requirements of Rule 506
         of Reg D, and the Company is not disqualified  from the exemption under
         Rule 506 of Reg D by virtue of Rule 507 of Reg D  because  neither  it,
         nor any of its  predecessors  or  affiliates  has been  subject  to any
         order,  judgment,  or  decree of any  court of  competent  jurisdiction
         temporarily,  preliminarily  or  permanently  enjoining such person for
         failure to comply with Rule 503 of Reg D.

                  (u) FINDER'S FEE. Except for amounts paid or payable  pursuant
         to  the  Agency  Agreement,  this  Agreement  and  the  U.S.  Placement
         Agreement dated the date hereof between the Company and Dallas Research
         (the  "Dallas  Research  Agreement"),   neither  the  Company  nor  any
         Subsidiary  incurred any  liability  for, or is aware of any claim for,
         any finder's or broker's fees or similar  payments in  connection  with
         the Offering.

                  (v)  INTANGIBLES.  The  Company  and each  Subsidiary  owns or
         possesses  adequate and enforceable  rights to use all patents,  patent
         applications,  trademarks,  service marks,  copyrights,  rights,  trade
         secrets,  confidential information,  processes and formulations used or
         proposed  to be  used  in the  conduct  of its  business  as  currently
         conducted  (collectively,  the  "Intangibles").  To  the  best  of  the
         Company's  knowledge,  neither  the  Company  nor  any  Subsidiary  has
         infringed upon, or is presently  infringing  upon, the rights of others
         with  respect to the  Intangibles,  and  neither  the  Company  nor any
         Subsidiary  has  received  (i)  any  notice  that  it has  or may  have
         infringed  or is  infringing  upon the rights of others with respect to
         the  Intangibles,  or (ii) any  notice of  conflict  with the  asserted
         rights of others with respect to the Intangibles which could, singly or
         in the  aggregate,  materially  and  adversely  affect its  business as
         presently conducted or its prospects, financial condition or results of
         operations, and the Company does not know of any basis therefor. To the
         best of the  Company's  knowledge,  no others have  infringed  upon the
         Intangibles.

                  (w) LABOR RELATIONS. Except as disclosed in the Memorandum, no
         labor problem exists with the Company's employees or, to its knowledge,
         is imminent, which could have a material adverse effect on the Company.

                  (x) NO ADVERSE  CHANGE.  Since the date of the latest  audited
         financial  statements in the Memorandum,  except as otherwise stated in
         the Memorandum, the



                                                     - 10 -

         Company has not (i)  incurred any  material  liability  or  obligation,
         direct or contingent, or entered into any material transaction, whether
         or not in the ordinary  course of business,  or sustained  any material
         loss or  interference  with its business from fire,  storm,  explosion,
         flood or other casualty,  whether or not covered by insurance,  or from
         any labor dispute or court or governmental action, order or decree, and
         (ii) there  have not been,  and prior to the Final  Closing  Date there
         will not be, any changes in the capital stock or any material increases
         in the long-term debt of the Company or any material  adverse change in
         or affecting  the general  affairs,  management,  financial  condition,
         shareholders'  equity,  results  of  operations  or  prospects  of  the
         Company.

         In addition,  any  certificate  signed by an officer of the Company and
delivered  to  Sunrise,  or to  counsel  for  Sunrise,  shall be  deemed to be a
representation  and warranty by the Company to Sunrise as to the matters covered
thereby.

         6.       COVENANTS OF THE COMPANY.

                  (a) PLACEMENT  MEMORANDUM.  The Company will furnish  Sunrise,
         without  charge,  with as many copies of the  Memorandum as Sunrise may
         reasonably  request.  If, prior to the Final  Closing  Date,  any event
         occurs as the  result  of which  the  Memorandum,  as then  amended  or
         supplemented,  would include an untrue statement of a material fact, or
         omit to state a material fact necessary in order to make the statements
         made,  in light of the  circumstances  in which  they  were  made,  not
         misleading,  or if it shall be  necessary  to amend or  supplement  the
         Memorandum to comply with  applicable  law, the Company will  forthwith
         notify Sunrise  thereof and furnish to Sunrise,  in such  quantities as
         Sunrise may reasonably request,  an amended or supplemental  Memorandum
         which corrects such statements or omissions or causes the Memorandum to
         comply  with  applicable  law.  Without  the prior  written  consent of
         Sunrise,  no copies of the Memorandum or any other material prepared by
         the  Company  in  connection  with  the  Offering  will be given by the
         Company or its counsel,  or by any  employee,  director or agent of the
         Company,  to any person in the United States except as  contemplated by
         the Dallas Research Agreement.

                  (b) ADDITIONAL  INFORMATION.  The Company will furnish Sunrise
         with  such  other  information,  documents  and  instruments  as may be
         required  for an  offer  made  solely  to  accredited  investors  under
         Sections 3(b), 4(2) or 4(6) of the Securities Act and Reg D.

                  (c) STATE SECURITIES  QUALIFICATION.  The Company will provide
         Sunrise's counsel with all information which such counsel determines to
         be necessary and otherwise  cooperate with such counsel, to permit such
         counsel to take all  necessary  action to (i) qualify or  register  the
         Special  Warrants for sale under the Blue Sky laws of the states of the
         United States in which Sunrise  determines that offers or sales will be
         made,



                                                     - 11 -

<PAGE>



         or (ii) obtain an exemption from such  qualification or registration in
         such states. The Company will promptly advise Sunrise:

                           (A)  Of  any  order,   request  or  suggestion  by  a
                  securities  regulator  of any state for any  amendment  to the
                  Memorandum  or any other filed  materials,  or for  additional
                  information; and

                           (B) Of any action by a  securities  regulator  of any
                  state  suspending the  registration  or  qualification  of the
                  Special Warrants for offer or sale in such state or denying an
                  exemption from such registration or  qualification,  or of the
                  initiation or threat of any proceeding  for such purpose,  and
                  the Company  will use its best efforts to prevent such action,
                  or if such  action  shall be taken,  to obtain the  withdrawal
                  thereof at the earliest practicable date.

         The Company will provide Sunrise any additional information,  documents
         and  instruments  which Sunrise shall deem necessary to comply with the
         rules,  regulations and judicial and administrative  interpretations in
         those  states and  jurisdictions  where the Special  Warrants are to be
         offered for sale or sold.  The Company will  co-operate  with Sunrise's
         counsel in filing all post-Offering  forms,  documents or materials and
         take all other  post-Offering  actions required by the Blue Sky laws of
         the states in which the Special Warrants have been offered or sold.

                  (d) USE OF PROCEEDS.  The Company will use its reasonable best
         efforts to use the net  proceeds  of the  Offering  as set forth in the
         Memorandum under the caption "Use of Proceeds."

                  (e) REG D  COMPLIANCE;  PROSPECTUS  UNDERTAKINGS.  The Company
         will comply in all respects with the terms and  conditions of Reg D and
         applicable  Blue Sky laws with  respect to the offering and the sale of
         the Special Warrants only to "accredited  investors" within the meaning
         of Rule 501(a) of Reg. D. The Company  will  perform and fulfill in all
         respects  the  agreements  and  undertakings  made by it in the  Agency
         Agreement and the  Subscription  Agreements  with respect to filing and
         obtaining receipts for a prospectus in Canada.

                  (f)  RESTRICTION ON ISSUANCE OF SECURITIES.  During the period
         commencing on the date hereof and terminating on the Final Closing Date
         the Company  will not,  without the prior  written  consent of Sunrise,
         issue any securities  other than upon the exercise of rights to acquire
         such  securities  exercised  by  holders  of  outstanding   Convertible
         Securities or Options of the Company  described in the  Memorandum  and
         other than stock  options  granted under the Plan  described  under the
         caption "Options to Purchase Shares" in the Memorandum.

                  (g)  REGISTRATION  RIGHTS.  The Company will  register  Common
         Shares under the  Securities  Act for the public resale  thereof in the
         United States in accordance with,



                                                     - 12 -

         and will be bound by the  provisions  of,  Exhibit B to this  Agreement
         which is incorporated herein by reference.

         7. ADDITIONAL REPRESENTATIONS AND COVENANTS OF THE COMPANY AND SUNRISE.

         7.1. The Company hereby  confirms the  representations,  warranties and
covenants  made by it in Schedule A to the Agency  Agreement as of the date made
and as of the date hereof.

         7.2.     The Company hereby represents and agrees to the following:

                  (a) The  Company  was on  September  23, 1996 (the date of the
         sale of September Special Warrants under the Canadian Offer) a "foreign
         issuer"  as  defined  in Rule  902(f) of  Regulation  S and  reasonably
         believes  that as of the date  hereof  there is and as of the  dates of
         issuance of the Special  Warrants  and the Common  Shares and  Warrants
         (collectively,  the  "Securities")  there will be no "substantial  U.S.
         market  interest"  (as defined in Rule 902(n) of  Regulation  S) in the
         Securities.

                  (b)  The  Company  is  not  an  open-end  investment  company,

         certificate  company that is  registered  or required to be  registered
         under the United States Investment Company Act of 1940, as amended.

                  (c)  Neither the  Company  nor any of its  affiliates  nor any
         person acting on its or their behalf (other than the Agent, Sunrise and
         Dallas Research,  as to which the Company makes no representation)  has
         taken  or will  take any  action  which  would  cause  the safe  harbor
         provision  afforded by Rule 903 of Regulation S to be  unavailable  for
         the Canadian Offer or the private offering exemption under Section 4(2)
         of the Securities Act to be unavailable  for the Sunrise Offer or which
         would  constitute  a  violation  of Rule 10b- 6 or Rule 10b-7 under the
         United  States  Securities  Exchange  Act  of  1934,  as  amended  (the
         "Exchange Act") under the Exchange Act.

                  (d) None of the Company,  its  affiliates or any person acting
         on its or their  behalf  (other  than the  Agent,  Sunrise  and  Dallas
         Research as to which the Company makes no  representation)  has offered
         or will  offer to sell the  Securities  by means of any form of general
         solicitation or general  advertising (as those terms are used in Reg D)
         or in any manner  involving  a public  offering  within the  meaning of
         Section 4(2) of the Securities Act.

                  (e)  Neither the  Company  nor its  affiliates  nor any person
         acting on its or their behalf (other than the Agent, Sunrise and Dallas
         Research as to which the Company makes no  representation)  has offered
         or will offer any of the Securities other than pursuant to the Canadian
         Offer, the Dallas Research  Agreement and this Agreement or has made or
         will make any  "directed  selling  efforts"  within the meaning of Rule
         902(b) of  Regulation S with respect to the  Securities,  to the extent
         that any such action would



                                                     - 13 -

         cause the  exemption  afforded by  Regulation S to be  unavailable  for
         offers and sales in the Canadian Offer.

         7.3      Sunrise represents and agrees to the following:

                  (a) it  will  comply  in  all  respects  with  the  terms  and
         conditions  of Reg D and  applicable  Blue Sky laws with respect to the
         offering  and the  sale of the  Special  Warrants  only to  "accredited

                  (b) it will not make offers or sales of the  Special  Warrants
         in any  jurisdiction  in  which  the  Special  Warrants  have  not been
         qualified or registered,  or are not exempt from such  qualification or
         registration.

                  (c) it has not and will not  engage in any  "directed  selling
         efforts"  within the meaning of Rule 902(b) of  Regulation  S or in any
         general  solicitation  or  advertising  within the  meaning of Reg D in
         connection with the Sunrise Offer, and (e) it has not and will not take
         any action in connection with the Sunrise Offer that would constitute a
         violation of Rule 10b-6 or 10b-7 under the Exchange Act.

         8.(a) CONDITIONS TO SUNRISE'S  OBLIGATIONS.  The obligations of Sunrise
hereunder  on  each  Closing  Date  will  be  subject  to  the  accuracy  of the
representations  and warranties of the Company  contained  herein as of the date
hereof and as of such Closing Date, to the performance by the Company of all its
obligations hereunder and to the following additional conditions:

                           (i) DUE  QUALIFICATION OR EXEMPTION.  (A) The Sunrise
                  Offer will have been  registered  or  qualified,  or be exempt
                  from registration or qualification, under the Blue Sky laws of
                  all necessary  states pursuant to Section 6(c) above,  and (B)
                  no order suspending the offer or sale of the Special Warrants,
                  will  have  been  issued  by  the   Commission  or  any  other
                  governmental  authority,  and no  proceeding  for that purpose
                  will have been initiated or threatened;

                           (ii) NO MATERIAL MISSTATEMENTS. Sunrise will not have
                  notified  the  Company  that  any  Blue  Sky law  filing,  the
                  Memorandum or any amendment or supplement  thereto contains an
                  untrue  statement  of a fact  which in  Sunrise's  opinion  is
                  material,  or omits to state a fact  which in its  opinion  is
                  material and is required to be stated  therein or is necessary
                  to make the statements therein not misleading;

                           (iii) CERTIFICATE OF CHAIRMAN.  The Company will have
                  delivered to Sunrise a certificate of the Company's  Chairman,
                  dated as of such  Closing  Date,  to the  effect  that all the
                  representations  and  warranties  of the  Company set forth in

                           (iv) OPINION OF COUNSEL.  Sunrise will have  received
                  from  Ballem  MacInnes,  counsel  to  the  Company,  a  signed
                  opinion,  dated as of such Closing Date,  substantially in the
                  form attached as Exhibit C hereto or in such other form as may
                  be proposed by Ballem  MacInnes and is  acceptable  to Sunrise
                  and its counsel; and

                           (v) LOCK-UP  AGREEMENTS.  Sunrise will have  received
                  from each  director  and each officer of the Company a written
                  undertaking  in the  form  of  Exhibit  D  hereto  prohibiting
                  dispositions  of Common Shares and other equity  securities of
                  the Company  without the prior  written  consent of Sunrise at
                  any time prior to the date specified therein.

                  (b) CONDITIONS OF THE COMPANY'S  OBLIGATIONS.  The obligations
         of the Company  hereunder  on each  Closing Date will be subject to the
         accuracy of the  representations  and  warranties of Sunrise  contained
         herein  as of the  date  hereof  and as of such  Closing  Date,  to the
         performance  by  Sunrise  of  its  obligations  hereunder  and  to  the
         following additional conditions:

                           (i) ABSENCE OF GOVERNMENT ACTION. No order suspending
                  the  offer or sale of the  Special  Warrants  will  have  been
                  issued by the Commission or any other governmental  authority,
                  and no proceeding for that purpose will have been initiated or
                  threatened; and

                           (ii) NO MATERIAL MISSTATEMENTS.  The Company will not
                  have  notified  Sunrise  that  any Blue  Sky law  filing,  the
                  Memorandum or any amendment or supplement  thereto contains an
                  untrue  statement of a fact which in the Company's  opinion is
                  material,  or omits to state a fact  which in its  opinion  is
                  material and is required to be stated  therein or is necessary
                  to make the statements  therein not  misleading,  in each case
                  only with respect to information  contained therein concerning
                  Sunrise.

         9. EXPENSES OF SALE. In addition to those items  referred to in Section
4  hereof,  the  Company  will pay or cause to be paid all  costs  and  expenses

sale in the  applicable  states  as  provided  in  Section  6(c),  or  obtaining

         10.  INDEMNIFICATION AND CONTRIBUTION.

                  (a)  INDEMNIFICATION  BY THE  COMPANY.  The Company  agrees to
         indemnify  and hold  harmless  Sunrise  and each  person,  if any,  who
         controls  Sunrise within the meaning of the Securities Act, against any
         losses,  claims,  damages or  liabilities,  joint or several,  to which
         Sunrise  or such  controlling  person  may  become  subject,  under the
         Securities Act or otherwise, insofar as such losses, claims, damages or
         liabilities  (or actions in respect  thereof) arise out of or are based
         upon (i) any untrue statement or alleged untrue statement of a material
         fact contained (A) in the Memorandum, or (B) in any Blue Sky law filing
         to the extent such statement was based on information  furnished by the
         Company,  or (ii) the  omission  or  alleged  omission  to state in the
         Memorandum or in any Blue Sky law filing a material fact required to be
         stated therein or necessary in order to make the statements therein, in
         the  light  of the  circumstances  under  which  they  were  made,  not
         misleading; and will reimburse Sunrise and each such controlling person
         for any legal or other expenses  reasonably incurred by Sunrise or such
         controlling  person in connection with  investigating  or defending any
         such  loss,  claim,  damage,  liability  or action;  provided  that the
         Company will not be liable in any such case to the extent that any such
         loss,  claim,  damage or  liability  arises  out of or is based upon an
         untrue  statement  or alleged  untrue  statement or omission or alleged
         omission made in the Memorandum in reliance upon and in conformity with
         written  information  furnished to the Company by Sunrise  specifically
         for use in the Memorandum.

                  (b)  INDEMNIFICATION  BY SUNRISE.  Sunrise agrees to indemnify
         and hold harmless the Company and each person, if any, who controls the
         Company  within the meaning of the  Securities  Act against any losses,
         claims, damages or liabilities,  joint or several, to which the Company
         or such controlling person may become subject, under the Securities Act
         or otherwise,  insofar as such losses,  claims,  damages or liabilities
         (or actions in respect  thereof) arise out of or are based upon (i) any
         untrue  statement  or  alleged  untrue  statement  of a  material  fact
         contained (A) in the  Memorandum,  or (B) in any Blue Sky filing to the
         extent such statement  relates solely to Sunrise,  or (ii) the omission
         or alleged  omission to state a material  fact required to be stated in
         the  Memorandum  or (to the extent such omission was of a material fact
         relating solely to Sunrise) in any Blue Sky law filing, or necessary in
         order to make the statements therein, in the light of the circumstances
         under which they were made, not misleading;  provided that Sunrise will
         be liable in any such case based on the  Memorandum  only to the extent
         that such untrue  statement or alleged untrue  statement or omission or
         alleged  omission in the  Memorandum  was made in reliance  upon and in
         conformity with written information furnished to the Company by Sunrise
         specifically for use in the Memorandum.

                  (c) PROCEDURE.  Promptly after receipt by an indemnified party
         under this Section 10 of notice of the commencement of any action, such
         indemnified  party  will,  if a claim in respect  thereof is to be made
         against any indemnifying party under this Section 10, notify in writing
         the indemnifying party of the commencement thereof; and the omission so
         to notify the indemnifying  party will (unless the  indemnifying  party
         was  unaware  of such  action  and was  materially  prejudiced  by such
         omission) relieve it from



                                                     - 16 -

<PAGE>



         any liability under this Section 10 as to the particular item for which
         indemnification  is then being sought, but not from any other liability
         which it may have to any indemnified  party. In case any such action is
         brought against any indemnified  party, and it notifies an indemnifying
         party of the  commencement  thereof,  the  indemnifying  party  will be
         entitled to  participate  therein,  and to the extent that it may wish,
         jointly  with any other  indemnifying  party,  similarly  notified,  to
         assume the defense thereof, with counsel who shall be to the reasonable
         satisfaction  of such  indemnified  party,  and after  notice  from the
         indemnifying  party to such  indemnified  party of its  election  so to
         assume the defense thereof,  the indemnifying  party will not be liable
         to such indemnified  party under this Section 10 for any legal or other
         expenses  subsequently incurred by such indemnified party in connection
         with the defense thereof other than reasonable costs of  investigation;
         provided that if, in the reasonable  judgment of the indemnified party,
         it is advisable for the indemnified party to be represented by separate
         counsel,  the indemnified party shall have the right to employ a single
         counsel in each  jurisdiction to represent the indemnified  parties who
         may be  subject  to  liability  arising  out of any claim in respect of
         which  indemnity  may be  sought  by the  indemnified  parties  thereof
         against the indemnifying party, in which event the fees and expenses of
         such separate  counsel shall be borne by the  indemnifying  party.  Any
         such  indemnifying  party  shall not be liable to any such  indemnified
         party on  account  of any  settlement  of any claim or action  effected
         without the consent of such indemnifying party, which consent shall not
         be unreasonably withheld.

                  (d) CONTRIBUTION.  If the indemnification provided for in this
         Section 10 is  unavailable to any  indemnified  party in respect to any
         losses, claims,  damages,  liabilities or expenses referred to therein,
         then the indemnifying  party, in lieu of indemnifying  such indemnified
         party,   will  contribute  to  the  amount  paid  or  payable  by  such
         indemnified  party,  as a  result  of  such  losses,  claims,  damages,
         liabilities  or expenses (i) in such  proportion as is  appropriate  to
         reflect the relative  benefits received by the Company on the one hand,
         and  Sunrise  on the  other  hand,  from the  Offering,  or (ii) if the
         allocation  provided by clause (i) above is not permitted by applicable
         law,  in such  proportion  as is  appropriate  to reflect  not only the
         relative benefits referred to in clause (i) above but also the relative
         fault of the Company on the one hand, and of Sunrise on the other hand,
         in connection  with the statements or omissions  which resulted in such
         losses, claims,  damages,  liabilities or expenses as well as any other
         relevant  equitable  considerations.  The relative benefits received by
         the Company on the one hand,  and  Sunrise on the other hand,  shall be
         deemed  to be in the same  proportion  as the total  proceeds  from the
         Sunrise Offer before deducting expenses) received by the Company,  bear
         to the initial  value of the  compensation  and to Sunrise  pursuant to
         Section 4.1 of this Agreement. The relative fault of the Company on the
         one hand,  and  Sunrise  on the other  hand,  will be  determined  with
         reference to, among other things,  whether the untrue or alleged untrue
         statement of a material  fact or the omission to state a material  fact
         relates  to  information  supplied  by the  Company,  and its  relative
         intent, knowledge,  access to information and opportunity to correct or
         prevent such statement or omission.  The amount payable by a party as a
         result of the losses, claims, damages, liabilities or expenses referred
         to above will be deemed to include  any legal or other fees or expenses
         reasonably incurred by such party



                                                     - 17 -

         in connection with  investigating or defending any action or claim. The
         Company and Sunrise  agree that it would not be just and  equitable  if
         contribution  pursuant to this Section 10 were  determined  by pro rata
         allocation  or by any other  method of  allocation  which does not take
         into account the equitable  considerations  referred to in this Section
         10(d).

         11.   REPRESENTATIONS   AND   COVENANTS   TO  SURVIVE   DELIVERY.   All
representations,  warranties  and covenants of the Company and of Sunrise herein
will survive the delivery and execution hereof and each Closing  hereunder,  and
shall  remain  operative  and  in  full  force  and  effect  regardless  of  any
investigation made by or on behalf of Sunrise or any person who controls Sunrise
within the  meaning of the  Securities  Act, or by the Company or any person who
controls the Company within the meaning of the Securities  Act, and will survive
delivery  of  the  Special  Warrants  hereunder  and  any  termination  of  this
Agreement.

         12.  TERMINATION  BY SUNRISE.  Sunrise will have the right to terminate
this Agreement by giving written notice as herein specified, at any time:

                 (a) If the Company shall have failed,  refused,  or been unable
        to perform any of its obligations hereunder;

                 (b) If any  condition  set  forth in  Section  8 hereof  is not
        fulfilled; or

                 (c) If there has  occurred  an event  materially  or  adversely
        affecting the value of the Special Warrants.

If Sunrise elects to terminate  this Agreement  pursuant to this Section 12, the
Company will be notified  promptly in accordance with Section 13 hereof. If this
Agreement is terminated  pursuant to this Section 12 prior to the Final Closing,
the  Company   will   reimburse   Sunrise  for  all   reasonable   out-of-pocket
disbursements  (including fees and disbursements of Sunrise's  counsel) actually
incurred by Sunrise in  connection  with the Sunrise  Offer and not  theretofore
paid. Notwithstanding the foregoing,  nothing contained in this Section 12 shall
imply that Sunrise has undertaken  any  commitment to sell the Special  Warrants
other than to use its best efforts.

         13.  NOTICES.  Any notice  hereunder  shall be in writing  and shall be
effective  when  delivered  in person  or by  facsimile  transmission,  or seven

         1.       REGISTRATION UNDERTAKINGS.

                  (a) For the purpose of this Exhibit B, the term  "Registerable
Shares"  shall  mean the  Common  Shares of the  Company  issuable  upon (i) the
exercise or deemed exercise of the Special Warrants  (including the Compensation
Warrants) issued in connection with the Sunrise Offer;  (ii) the exercise of the
Warrants  issued upon the exercise or deemed  exercise of such Special  Warrants
and (iii) the exercise of the Sunrise  Warrants  issued upon the exercise of the
Sunrise Option.

                  (b) At any time prior to the fourth  anniversary  of the Final
Closing Date,  the holder or holders (the  "Holders") of at least twenty percent
(20%) of the  Registerable  Shares  (counting  as  Registerable  Shares for this
purpose  securities  referred to in Section 1(a) above that are  exercisable for
Registerable  Shares) may  request,  in writing,  that the Company  register for
resale  under the  Securities  Act not less  than  twenty  percent  (20%) of the
Registerable  Shares. The Company will give prompt written notice (the "Notice")
of such request to each other Holder and will, as promptly as  practicable  (but
in any event within 60 days),  after  receipt of such  request  prepare and file
with the United States Securities and Exchange Commission (the "Commission") (at
the Company's own expense) a  registration  statement  under the  Securities Act
sufficient to permit the public offering of the Registerable Shares specified by
the Holders in the aforementioned  request and such other Registerable Shares as
may be specified by other Holders by written  notice to the Company given within
twenty (20) days after the receipt by them of the Notice.  The Company  will use
its  reasonable  best  efforts to cause such  registration  statement  to become
effective  under the Securities  Act as promptly as practicable  and to maintain
such  effectiveness  so as to permit resale of the  Registerable  Shares covered
thereby  until the  earlier of the time that all such  Registerable  Shares have
been sold and the time that all such Registerable Shares may be sold pursuant to
the  provisions  of Rule 144(k)  under the  Securities  Act;  provided  that the
Company shall only be obligated to file one such  registration  statement  under
this Section 1(b).

                  (c) If at any time from and after the Final  Closing  Date the
Company  proposes to register any of its securities under the Securities Act (on
a form other than Form S-4 or S-8 or their  equivalents),  the Company  will (i)
promptly notify all Holders that such  registration  statement will be filed and
that the  Registerable  Shares  which  are  then  held by such  Holders  will be
included in such registration statement at their request and (ii) subject to the
last sentence of this subsection (c), cause such registration statement to cover
all  Registerable  Shares  which  it has been so  requested  to  include  by the
Holders,  provided  such  request is  delivered to the Company not later than 20
days after  such  notice is given to the  Holders  and  specifies  the number of
Registerable  Shares to be  included  in the  proposed  registration  statement.
Notwithstanding the foregoing provisions, if such registration statement relates
to an  underwritten  offer of Common Shares and the managing  underwriter  shall
inform in writing  the Company and the  Holders  that the  managing  underwriter
believes that the number of shares requested to be included in such registration
statement would materially, adversely affect its



                                                     - 1 -

<PAGE>



ability  to  effect  such  offering,  then  the  Company  will  include  in such
registration  statement  the  number of Common  Shares  which the  Company is so
advised can be sold in (or during the time of) such offering as follows:  First,
all shares proposed by the Company to be sold for its own account,  and, second,
such Registerable Shares requested to be included in such registration, pro rata
by the Holders and other  security  holders  having  registration  rights on the
basis of the number of  Registerable  Shares and other Common Shares so proposed
to be sold by the Holders and by such other security holders and so requested to
be included;  PROVIDED, HOWEVER, that the Company shall be obligated to register
any   Registerable   Shares  and  other  Common  Shares  so  excluded  from  the
registration  statement pursuant to a registration  statement within ninety (90)
days after the  effectiveness  of such  registration  statement  or such greater
number of days as may be specified in "lock-up" agreements entered into with the
managing underwriter.

                  (d)  In  connection  with  any  registration  statement  filed
pursuant to this Section 1 (a "Registration Statement"),  the Company shall take
such action as may be necessary to register or qualify the  Registerable  Shares
registered  thereunder  under the  securities or blue sky laws of such states of
the United States as shall  reasonably be requested by the prospective  sellers,
and shall do any and all other  acts  which may be  necessary  or  advisable  to
permit the proposed sale or other disposition of such Registerable Shares in any
such  state;  provided  that in no event  shall  the  Company  be  obligated  in
connection  therewith to qualify as a foreign  corporation  in any  jurisdiction
where it is not  already  so  qualified,  or to  execute a general  consent  for
service of process in suits  other than those  arising out of the offer and sale
of the  Registerable  Shares,  or to take any action  which would  subject it to
taxation in any jurisdiction where it is not then so subject.

                  (e) The  Company's  obligations  to register and qualify under
this Section 1  Registerable  Shares of any Holder shall be  conditioned in each
instance  upon the timely  receipt by the Company in writing of (1)  information
from such  Holder  as to the  proposed  plan of  distribution  of such  Holder's
Registerable Shares to be included in the Registration  Statement,  and (2) such
other  information  as the Company may  reasonably  require from such Holder for
inclusion in the Registration Statement.

                  (f) All fees,  disbursements and out-of-pocket expenses (other
than any brokerage fees and commissions and legal fees of counsel to any Holder)
in  connection  with the  Registration  Statement  (or seeking or obtaining  the
opinion  of  counsel  to the  Company  under  Section  1(g) and,  if in the sole
discretion  of the  Company  deemed  desirable,  any  no-action  position of the
Commission  with respect to sales pursuant to Rule 144 under the Securities Act)
and in complying with  applicable  state  securities  laws shall be borne by the
Company.  The  Company at its expense  will  supply the Holders of  Registerable
Shares included in the Registration  Statement with copies of such  Registration
Statement and the prospectus  included  therein and in such quantities as may be
reasonably  requested by them. In connection with each  Registration  Statement,
the Company shall furnish to Holders of  Registerable  Shares  included  therein
with such opinions of counsel, comfort letters of accountants,  certificates and
such other documents that are customary in connection with  underwritten  public
offerings and that are reasonably requested by such Holders.

                  (g) The Company  shall not be  required  by this  Section 1 to
file any Registration Statement relating to Registerable Shares of any Holder if
the  Company  shall  furnish  such  Holder  with a written  opinion  of  counsel
reasonably  satisfactory  to such Holder to the effect that the proposed  public
offering or other transfer of  Registerable  Shares as to which  registration is
requested is exempt from the registration or  qualification  requirements of all
applicable  federal and state securities laws and would result in all purchasers
or  transferees   thereof   obtaining   securities  which  are  not  "restricted
securities" as defined in Rule 144 under the Securities Act.

                  (h) If, after the date of the  Memorandum,  the Company grants
to any person  registration  rights which are more favorable to such person than
those  afforded to the Holders  under this Section 1, the Holders  shall without
further action be entitled to the benefits of such more favorable rights.

         2.       INDEMNIFICATION.

                  (a) In the event of the filing of any  Registration  Statement
pursuant to Section 1 hereof,  the Company agrees to indemnify and hold harmless
each Holder of  Registerable  Shares  identified  as a selling  security  holder
therein and each person,  if any, who controls such Holder within the meaning of
the Securities Act, against any and all losses,  claims, damages or liabilities,
joint or several (including the costs of any reasonable  investigation and legal
and  other  expenses  incurred  in  connection  with,  and  any  amount  paid in
settlement  of, any action,  suit or proceeding or any claim  asserted) to which
they, or any of them, may become subject under the Securities  Act, the Exchange
Act or other  federal or state law or  regulation,  at common law or  otherwise,
insofar as such losses,  claims,  damages or liabilities  (or actions in respect
thereof)  arise out of or are based upon any untrue  statement or alleged untrue
statement of a material fact contained in such  Registration  Statement,  or any
related  preliminary  prospectus,  final  prospectus,  or  amendment  thereof or
supplement  thereto,  or arise out of or are based upon any  omission or alleged
omission  to state  therein a material  fact  required  to be stated  therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not misleading;  provided, however, that the Company shall
not be liable  under this  Section  2(a) in any such case to the extent that any
such losses,  claims,  damages or  liabilities  arise solely out of or are based
upon an untrue  statement of a material  fact  contained in or any omission of a
material fact from such Registration Statement,  preliminary  prospectus,  final
prospectus or amendment  thereof or supplement  thereto in reliance upon, and in
conformity with,  information furnished in writing to the Company by such Holder
specifically  for  use  therein.  This  indemnity  will  be in  addition  to any
liability which the Company may otherwise have.

                  (b) Each Holder of Registerable  Shares who is identified as a
selling security holder in a Registration  Statement referred to in Section 2(a)
will agree,  severally  and not  jointly,  to  indemnify  and hold  harmless the
Company,  each other person  referred to in subparts (1), (2) and (3) of Section
11(a) of the Securities Act in respect of such Registration Statement,  and each
person,  if any, who controls the Company or any such person  within the meaning
of Section 15 of the Securities Act, against any and all losses, claims, damages
or liabilities  (including costs of any reasonable  investigation  and legal and
other expenses incurred in



                                                     - 3 -

<PAGE>



connection  with,  and any amount paid in  settlement  of, any  action,  suit or
proceeding  or any claim  asserted)  to which they,  or any of them,  may become
subject under the Securities Act, the Exchange Act or other federal or state law
or  regulation,  at common law, or  otherwise,  insofar as such losses,  claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any  untrue  statement  or alleged  untrue  statement  of a  material  fact
contained in such Registration Statement, or any related preliminary prospectus,
final prospectus or amendment thereof or supplement  thereto, or arise out of or
are based upon any omission or alleged omission to state therein a material fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the circumstances  under which they were made, not misleading,  in each
case to the  extent,  but only to the  extent,  that such  untrue  statement  or
omission was made in such Registration Statement,  preliminary prospectus, final
prospectus or amendment  thereof or supplement  thereto in reliance upon, and in
conformity with,  information furnished in writing to the Company by such Holder
specifically  for use therein.  This indemnity  agreement will be in addition to
any liability which a Holder may otherwise have to the Company.

                  (c)  Any  party  that  proposes  to  assert  the  right  to be
indemnified under this Section 2 shall,  promptly after receipt of notice of the
commencement of any action,  suit or proceeding against such party in respect of
which a claim is to be made against an indemnifying  party or parties under this
Section 2,  notify each such  indemnifying  party of the  commencement  thereof,
enclosing  a copy of all  papers  served.  No  indemnification  provided  for in
Section  2(a) or 2(b)  shall be  available  to any party who shall  fail to give
notice as  provided  in this  Section  2(c) if the party to whom  notice was not
given was unaware of the  proceeding to which such notice would have related and
was materially prejudiced by the failure to give such notice but the omission so
to notify such indemnifying  party of any such action,  suit or proceeding shall
not  relieve it from any  liability  that it may have to any  indemnified  party
other  than under this  Section 2 or Section 3 below.  In case any such  action,
suit or proceeding is brought against any indemnified  party and it notifies the
indemnifying party of the commencement  thereof, such indemnifying party will be
entitled to  participate  in, and, to the extent that it may wish,  jointly with
any other indemnifying party similarly  notified,  to assume the defense thereof
with counsel  reasonably  satisfactory  to such  indemnified  party,  and, after
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense thereof and the approval by the indemnified  party of such
counsel (which shall not be unreasonably withheld), the indemnifying party shall
not be liable to such indemnified party for any legal or other expenses,  except
as  provided  below  and  except  for  the  reasonable  costs  of  investigation
subsequently  incurred by such indemnified  party in connection with the defense
thereof. The indemnified party shall have the right to employ its counsel in any
such action,  suit or proceeding but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the employment of counsel
by such  indemnified  party has been  authorized in writing by the  indemnifying
parties,  (ii) the indemnified party shall have reasonably  concluded that there
may be differing or additional  defenses  available to it and not to one or more
of the indemnifying  parties in such action, suit or proceeding so that it would
be  inappropriate  for counsel to represent both the  indemnified  party and the
indemnifying  party in view of actual or  potential  conflicts  of interest  (in
which case if such indemnified party notifies the indemnifying  party in writing
that it elects to employ  separate  counsel at the  expense of the  indemnifying
party, the



                                                     - 4 -

<PAGE>



indemnifying  party  shall  not have the  right to assume  the  defense  of such
action,  suit or proceeding on behalf of such indemnified  party);  or (iii) the
indemnifying  parties shall not have  employed  counsel to assume the defense of
such action within a reasonable time after notice of the  commencement  thereof,
in each of which cases the fees and expenses of the indemnified  party's counsel
shall be at the  expense  of the  indemnifying  parties,  it  being  understood,
however,  that the indemnifying party shall not, in connection with any one such
action,  suit or  proceeding  or separate but  substantially  similar or related
actions,  suits or proceedings in the same jurisdiction  arising out of the same
general  allegations or  circumstances,  be liable for the  reasonable  fees and
expenses of more than one separate  firm of attorneys  for the Holders and their
controlling persons,  which firm shall be designated in writing by a majority in
interest of such Holders (based upon the value of the securities included in the
Registration  Statement).  An  indemnifying  party  shall not be liable  for any
settlement of any action, suit, proceeding or claim effected without its written
consent.

         3.   CONTRIBUTION.   In  order  to  provide  for  just  and   equitable
contribution  in  circumstances  in which the  indemnification  provided  for in
Section 2 is due in  accordance  with its terms but for any reason is held to be
unavailable or insufficient to hold harmless an indemnified  party,  the Company
on the one hand and any Holder on the other hand shall,  in lieu of indemnifying
such indemnified party,  contribute to the aggregate losses,  claims, damages or
liabilities referred to in Section 2 above (including costs of any investigation
and legal and other  expenses  reasonably  incurred in connection  with, and any
amount paid in  settlement  of, any  action,  suit or  proceeding  or any claims
asserted),  in such  proportions  as is  appropriate  to  reflect  the  relative
benefits  received  by  the  Company  and  the  Holders  from  any  offering  of
Registerable  Shares and the  relative  fault of the  Company and such Holder in
connection  with the  statements  or  omissions  which  resulted in such losses,
claims,  damages,  liabilities  or  expenses,  as  well  as any  other  relevant
equitable considerations. The relative fault of the Company and any Holder shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or omission related to information  supplied
by the Company (including for this purpose information  supplied by any officer,
director,  employee or agent of the Company) or to written information furnished
to the  Company  by or on  behalf  of such  Holder  specifically  for use in the
preparation of the Registration Statement or any amendment thereof or supplement
thereto, and the parties' relative intent, knowledge,  access to information and
opportunity to correct or prevent such  statement or omission.  It is understood
and agreed that it would not be just and equitable if  contribution  pursuant to
this Section 3 were determined by pro rata allocation  (even if the Holders were
treated as one entity for such  purpose)  or by any other  method of  allocation
which does not take account of the equitable  considerations  referred to above.
Notwithstanding  the  provisions  of this  Section 3 in no case shall any Holder
(except as may be provided by agreement among them) be liable or responsible for
any amount in excess of the  proceeds  received  by such Holder from the sale of
the  Registerable  Shares  included  in the  Registration  Statement,  provided,
however,  that no person  guilty of  fraudulent  misrepresentation  (within  the
meaning  of  Section  11(f)  of  the  Securities   Act)  shall  be  entitled  to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation.  For  purposes of this  Section 3, each  person,  if any, who
controls a Holder  within the  meaning  of Section 15 of the  Securities  Act or
Section 20(a) of the Exchange Act shall have the same rights to  contribution as
such  Holder,  and each person,  if any,  who  controls  the Company  within the
meaning of the



                                                     - 5 -

<PAGE>



Section 15 of the  Securities  Act or Section  20(a) of the Exchange  Act,  each
director of the  Company  and each  officer of the Company who shall have signed
the  Registration  Statement  shall have the same rights to  contribution as the
Company,  subject to the immediately  preceding  sentence of this Section 3. Any
party  entitled  to  contribution  will,  promptly  after  receipt  of notice of
commencement of any action,  suit or proceeding against such party in respect of
which a claim for  contribution  may be made  against  another  party or parties
under this Section 3, notify such party or parties from whom contribution may be
sought,  and  the  omission  so to  notify  such  party  or  parties  from  whom
contribution  may be  sought  shall  relieve  the  party or  parties  from  whom
contribution  may be sought (if such  party was  unaware  of such  action  suit,
proceeding  and was  materially  prejudiced by such omission) from any liability
under  this  Section  3, but not from any other  obligation  it or they may have
hereunder  or other  than under  this  Section  3. No party  shall be liable for
contribution with respect to the settlement of any action,  suit,  proceeding or
claim effected  without its written  consent.  The obligations of the Holders to
contribute  pursuant  to this  Section  3 are  several  in  proportion  to their
respective number of Registerable Shares included in the Registration  Statement
and not joint.

                           OPINION OF COMPANY COUNSEL


         (A) The Company is a corporation  duly organized,  validly existing and
in good  standing  under  the laws of  Alberta,  with full  corporate  power and
authority to own or lease and operate its properties and to conduct its business
as described in the Memorandum.

         (B) The  Company is the direct or indirect  beneficial  owner of all of
the outstanding  securities of each of the corporations (a "Subsidiary")  listed
in  Section  5(b)  of  the  U.S.  Placement  Agreement.  Each  Subsidiary  is  a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation,  with full power and authority,  corporate
and  other,  to own or lease and  operate  its  properties  and to  conduct  its
business  as  currently  conducted,  and is duly  qualified  to do business as a
foreign  corporation  and is in good  standing in all  jurisdictions  where such
qualification is necessary and where failure so to qualify could have a material
adverse  effect on its financial  condition,  results of  operations,  business,
properties  or  prospects.  Except  for the  Subsidiaries,  the  Company  has no
subsidiaries.


         (C) Except as may be required under  applicable  securities laws in the
United States, no authorization, approval, consent, order, registration, license
or permit of any court or governmental  agency or body is required for the valid
authorization,  issuance,  sale and delivery of the Special Warrants, the Common
Shares and Warrants issuable upon exercise of the Special Warrants,  the Sunrise
Option, the Sunrise Warrants and the Common Shares issuable upon the exercise of
any  of  the  foregoing,  and  the  consummation  by  the  Company  of  all  the
transactions contemplated by the Subject Agreements.

         (D) The Company has full power and authority,  corporate and other,  to
execute,  deliver  and  perform the Subject  Agreements  and to  consummate  the
transactions  contemplated  thereby. The execution,  delivery and performance of
the Subject  Agreements by the Company,  the  consummation by the Company of the
transactions  therein  contemplated,  and the compliance by the Company with the
terms of the  Subject  Agreements  have been duly  authorized  by all  necessary
corporate action on the part of the Company.  Each of the Subject Agreements has
been duly executed and delivered by the Company and, assuming due authorization,
execution  and  delivery by the other  parties  thereto,  is a valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms,  except insofar as enforcement  may be limited by applicable  bankruptcy,
insolvency,  reorganization,  moratorium  and other laws affecting the rights of
creditors  generally  and by the  discretion  of  courts in  granting  equitable
remedies,  and except that enforceability of the indemnification  provisions and
the  contribution  provisions set forth in the U.S.  Placement  Agreement may be
limited  by the  securities  laws in the  United  States  or the  public  policy
underlying such laws.

         (E) The execution,  delivery and performance of the Subject  Agreements
by the Company,  the  consummation  by the Company of the  transactions  therein
contemplated, and the


<PAGE>



compliance  by the Company with the terms of the Subject  Agreements do not, and
will not,  with or without  the giving of notice or the lapse of time,  or both,
(1) result in a violation of the constating documents of the Company, (2) result
in a breach of or conflict  with any terms or  provisions  of, or  constitute  a
default under, or result in the modification or termination of, or result in the
creation or imposition of any lien,  security  interest,  charge or  encumbrance
upon any of the properties or assets of the Company  pursuant to, any indenture,
mortgage,  note, contract,  commitment or other agreement or instrument of which
we are aware and to which the  Company is a party or by which the Company or any
of its  properties  or assets are or may be bound or  affected,  (3) violate any
existing applicable law, rule, regulation or, to the best of our knowledge,  any
judgment,  order or decree of any  governmental  agency  or court,  domestic  or
foreign,  having  jurisdiction  over the  Company  or any of its  properties  or
businesses,   or  (4)  have  any   material   adverse   effect  on  any  permit,
certification,  registration,  approval, consent, license or franchise necessary
for the Company to own or lease and operate any of its properties and to conduct
its business or the ability of the Company to make use thereof.

         (F) The Common Shares conform to the description  thereof  contained in
the  Memorandum   under  the  caption   "Description  of  Securities."  All  the
outstanding  Common Shares have been duly  authorized and validly issued and are
fully paid and  nonassessable.  Except as set forth in Section  5(e) to the U.S.
Placement Agreement, there are no outstanding securities convertible into Common
Shares  ("Convertible  Securities") or any options,  warrants or other rights to
purchase  any Common  Shares or  Convertible  Securities  ("Options").  All such
Options constitute the valid and binding obligations of the Company, enforceable
against the  Company in  accordance  with their  respective  terms.  None of the
outstanding Common Shares,  Options or Convertible Securities has been issued in
violation of the preemptive  rights of any  securityholder  of the Company,  and
none of the holders of the  outstanding  Common  Shares,  Options or Convertible
Securities  is subject to  personal  liability  solely by reason of being such a
holder.  The offers and sales of the  outstanding  Common  Shares,  Options  and
Convertible  Securities  were in full  compliance  with all applicable  Canadian
federal  and  provincial  laws.  To  the  best  of  our  knowledge,   after  due
investigation,  except as described in the  Memorandum or as provided in Section
5(e) of the U.S. Placement  Agreement,  no holder of any of the Company's issued
securities  has any rights  ("demand,"  "piggyback"  or  otherwise) to have such
securities registered under the Securities Act.

         (G) The  issuance  and  sale of the  Special  Warrants  (including  the
Compensation  Warrants),   the  Warrants,  and  the  Sunrise  Warrants  and  the
securities   issuable  upon  the  exercise  of  such  warrants  have  been  duly
authorized, and when they are issued as contemplated by the Agreements,  will be
validly issued, and, in the case of Common Shares, fully paid and nonassessable,
and the  holders  thereof  will not be subject to personal  liability  solely by
reason of being such holders.  None of such warrants or other securities will be
subject to preemptive rights of any security-holder of the Company.

         (H) The  certificates  representing  the securities  referred to in (G)
above are in proper legal form.



<PAGE>



         (I)  The  descriptions  in the  Memorandum  of  statutes,  regulations,
government classifications, contracts, instruments and other documents have been
reviewed  by us and,  based  upon such  review,  are  accurate  in all  material
respects and present fairly the information required to be disclosed,  and there
are no material statutes,  regulations or government  classifications or, to the
best of our knowledge, after due investigation, material contracts or documents,
which should be described in the Memorandum  that are not so described.  None of
the material provisions of the contracts or instruments described above violates
any existing applicable law, rule, regulation, or, to the best of our knowledge,
any  judgment,  order or  decree  of any  governmental  agency  or court  having
jurisdiction over the Company or any of its assets or businesses. To the best of
our  knowledge,  the Company is not in default  under any  contract or agreement
material  to its  business  or under any  promissory  note or other  evidence of
indebtedness for borrowed funds.

         (J) Upon delivery of the Special  Warrants  (including the Compensation
Warrants) and the Sunrise Warrants as provided in the U.S. Placement  Agreement,
the persons acquiring the same will acquire good title thereto free and clear of
all liens,  encumbrances,  equities,  security interests and claims,  other then
such liens, encumbrances,  equities,  security interests or claims placed on the
securities by such persons.

         (K) To the best of our knowledge, after due investigation,  the Company
is not in violation  of, or in default  under,  any term or provision of (i) its
constating  documents,  (ii) any indenture,  mortgage,  contract,  commitment or
other  agreement or  instrument  to which it is a party or by which it or any of
its properties or business is or may be bound or subject,  or (iii) any existing
applicable law, rule, regulation,  judgment, order or decree of any governmental
agency or court, Canadian or otherwise,  having jurisdiction over the Company or
any Subsidiary or any of their respective properties or businesses.  The Company
owns,  possesses or has obtained all governmental  and other licenses,  permits,
certifications,  registrations,  approvals or consents and other  authorizations
necessary to own or lease, as the case may be, and to operate its properties and
to conduct its business as currently  conducted and described in the Memorandum,
and  all  such  licenses,  permits,  certifications,  registrations,  approvals,
consents and other  authorizations are outstanding and in good standing.  To the
best of our knowledge, after due investigation, there are no proceedings pending
or threatened,  nor is there any basis therefor, seeking to cancel, terminate or
limit  such  licenses,  permits,  certifications,  registrations,  approvals  or
consents or authorizations.

         (L) To the best of our knowledge, after due investigation, there are no
claims, actions, suits, proceedings,  arbitrations,  investigations or inquiries
before any governmental  agency,  court or tribunal,  Canadian or otherwise,  or
before any  private  arbitration  tribunal,  pending or  threatened  against the

                  Laurie Van Duivenbode                        205,169

At the Closing,  Purchaser  shall pay the Purchase Price to Sellers by certified
or cashier's check.

         1.4 Purchase Price Adjustments.  The Purchase Price shall be subject to
post- closing adjustment as set forth below:

                  (a)  Accounts  Receivable.  On the  200th  day  following  the
         Closing,  Sellers shall  reimburse  Purchaser on a pro rata basis in an
         amount equal to the total of the accounts  receivable  reflected on the
         Statement of Net Working  Capital (as defined in  subsection  1.4(c)(i)
         below) net of the allocable portion of the reserve for bad debts, which
         remain  uncollected  as of such date  provided that with respect to the
         accounts  receivable  listed on Schedule  1.4(a) attached  hereto,  the
         reimbursement  date shall be the first anniversary of the Closing date.
         Upon such reimbursement,  the uncollected accounts shall be assigned to
         Sellers. During such 200-day period (or the 365-day period with respect
         to the  accounts  receivable  listed on  Schedule  1.4(a),  Sellers may
         participate in the collection process of such accounts  receivable.  In
         the  event  the  total  amount   collected  with  respect  to  accounts
         receivable  reflected on the Statement of Net Working  Capital  exceeds
         the amount of such accounts  receivable net of the  applicable  reserve
         for bad debts,  Purchaser  shall pay the excess to Sellers  pro rata on
         the 200th day following Closing.

                  (b) Liabilities.  Sellers  acknowledge that the Purchase Price
         was negotiated on the  assumption  that Company would have no long-term
         liabilities,  including  debt. In the event that at Closing Company has
         long-term  liabilities,  Sellers shall pay to Purchaser,  on a pro rata
         basis, an amount equal to the total of any such long-term liabilities.

                  (c) Net Working Capital Adjustment.

                           (i) For  purposes  of this  Agreement,  "Net  Working

                  (i) all hearing  aids ordered but not fitted to the patient as
                  of  the  Closing   date  will  not  be  included  in  accounts
                  receivable  and (ii) all payments made by Company with respect
                  to such hearing aid orders shall be treated as prepaid items.

                           (ii)  As  promptly  as   practicable   following  the
                  Closing,  but in no  event  later  than  45  days  thereafter,

                  agreeable statement of the Net Working Capital which shall set
                  forth the  computation  and  components  thereof in reasonable
                  detail (the "Statement of Net Working Capital").

                           (iii) On the  fifteenth  day  after the date on which
                  the  Statement of Net Working  Capital is  completed  (or such
                  earlier  date as such  statement  is  mutually  agreed upon by
                  Sellers and  Purchaser in writing),  (i) in the event that the
                  Net Working Capital exceeds $150,000, then Purchaser shall pay

                  Sellers  shall pay to Purchaser,  pro rata,  the amount of the
                  deficiency.

                  efforts to avoid any act, or any  omission  to act,  which may

         Statement  of Net  Working  Capital it has been  agreed that no accrual
         shall be made for sick and vacation pay  entitlements  for employees of

         to  make to  former  employees  of  Company  who  become  employees  of
         Purchaser  and whose  employment  terminates  for any reason within the

obtained, Purchaser will indemnify and hold the Sellers harmless with respect to
any  loss,  cost,  or  expense  the  Sellers  may incur as a result of not being
released.

         Purchaser  (and  its  directors,  officers,  shareholders,   employees,
         affiliates,  agents and assigns)  harmless  from and against all Claims
         (as defined  below)  asserted  against,  resulting to, imposed upon, or

         Agreement. The indemnification  obligation of Sellers hereunder is with

                           (v) Any Claims shall be asserted by Purchaser jointly
                  against Sellers on a uniform basis and any waiver,  compromise
                  or settlement of a Claim offered by Purchaser shall be offered
                  on the same terms to all Sellers.

                  (b) Purchaser's right to  indemnification  as provided in this
         Section 8.1 shall not be eliminated,  reduced or modified in any way as
         a result  of the fact  that (i)  Purchaser  had  notice  of a breach or
         inaccuracy of any representation, warranty or covenant contained herein
         (except as set forth in the  Disclosure  Schedule),  (ii) Purchaser had
         been provided with access,  as requested by Purchaser,  to officers and
         employees  of the  Company  and  such of  Company's  books,  documents,
         contracts  and records as has been provided to Purchaser in response to
         Purchaser's requests.

         8.2 Indemnification by Purchaser. Purchaser hereby agrees to indemnify,
defend,  and hold  harmless  the Sellers  from and  against all Claims  asserted
against,  resulting to,  imposed  upon,  or incurred by the Sellers  directly or
indirectly by reason of, arising out of, or resulting from (a) the inaccuracy or
breach of any  representation  or warranty  of  Purchaser  contained  in or made
pursuant to this Agreement or in any of the documents delivered pursuant hereto,
or (b) the  non-performance  or breach of any covenant,  term or provision to be
performed by Purchaser  contained in this  Agreement or in any of the  documents
delivered pursuant hereto. The indemnification obligation of Purchaser hereunder
is with respect to the full amount of the Claims.

         8.3  Notice;  Defense  of  Claims.  If a claim is to be made by a party
entitled   to   indemnification   hereunder,   the   party   entitled   to  such
indemnification  shall give written notice to the indemnifying party immediately
after the party entitled to indemnification becomes aware of any fact, condition
or event  which  may give  rise to a matter  for  which  indemnification  may be
sought; provided that the failure of any indemnified party to give timely notice
shall not affect the rights to  indemnification  hereunder  except to the extent
that the indemnifying party  demonstrates  actual damage caused by such failure.
If any lawsuit or enforcement  action is filed against any party entitled to the
benefit of indemnity hereunder,  and if the indemnifying party shall acknowledge
in  writing  to the  indemnified  party  that the  indemnifying  party  shall be
obligated  under the terms of its indemnity  hereunder in  connection  with such
lawsuit,  action or claim, then the indemnifying party shall be entitled,  if it
so elects,  to take control of the defense and  investigation of such lawsuit or
action and to employ and engage attorneys of its own choice to handle and defend
the same, at the  indemnifying  party's cost, risk and expense provided that the
indemnifying  party and its counsel  shall  proceed with  diligence  and in good
faith with  respect  thereto.  The  indemnified  party  shall  cooperate  in all
reasonable  respects  with the  indemnifying  party  and such  attorneys  in the
investigation,  trial and  defense  of such  lawsuit  or action  and any  appeal
arising therefrom; provided, however, that the indemnified party may, at its own
cost,  participate  in the  investigation,  trial and defense of such lawsuit or
action and any appeal arising therefrom.

         8.4 Survival of  Representations.  All  representations  and warranties
made by the  parties  in this  Agreement  are  made  only as of the date of this
Agreement but will survive the consummation of the transactions  contemplated by
this Agreement until October 31, 1998

         9.11     Resolution of Disputes.

                  (a) Arbitration. Any dispute, controversy or claim arising out
         of or relating to this  Agreement or the  performance by the parties of
         its terms shall be settled by binding  arbitration held in Los Angeles,
         California,  in accordance with the Commercial Arbitration Rules of the
         American Arbitration Association then in effect, except as specifically
         otherwise provided in this Section 9.11. Notwithstanding the foregoing,
         HealthCare,   in  its  discretion,   apply  to  a  court  of  competent
         jurisdiction  for  equitable  relief from any  violation or  threatened
         violation of the covenants of the Shareholders  under Section 5.1(b) of
         this Agreement.

                  (b)  Arbitrators.  If the matter in controversy  (exclusive of
         attorney fees and expenses) shall appear,  as at the time of the demand
         for  arbitration,  to exceed  $50,000,  then the panel to be  appointed
         shall  consist of three  neutral  arbitrators;  otherwise,  one neutral
         arbitrator.

                  (c) Procedures;  No Appeal. The arbitrator(s) shall allow such
         discovery  as  the  arbitrator(s)   determine   appropriate  under  the
         circumstances  and  shall  resolve  the  dispute  as  expeditiously  as
         practicable,  and if reasonably practicable,  within 120 days after the
         selection  of the  arbitrator(s).  The  arbitrator(s)  shall  give  the
         parties written notice of the decision,  with the reasons  therefor set
         out,  and shall have  thirty (30) days  thereafter  to  reconsider  and
         modify  such  decision  if any party so  requests  within ten (10) days
         after the decision. Thereafter, the decision of the arbitrator(s) shall
         be final,  binding,  and  nonappealable  with  respect to all  persons,
         including  (without  limitation)  persons who have failed or refused to
         participate in the arbitration process.

                  (d) Authority. The arbitrator(s) shall have authority to award
         relief  under  legal or  equitable  principles,  including  interim  or
         preliminary relief, and to allocate responsibility for the costs of the
         arbitration and to award recovery of attorney fees and expenses in such
         manner as is determined to be appropriate by the arbitrator(s).

                  (e) Entry of Judgment. Judgment upon the award rendered by the
         arbitrator(s)  may be  entered  in any  court  having in  personam  and
         subject matter  jurisdiction.  The Shareholders  and HealthCare  hereby
         submit to the in personam  jurisdiction of the federal and state courts
         in California for the purpose of confirming any such award and entering
         judgment thereon.

                  (f) Confidentiality.  All proceedings under this Section 9.11,
         and  all  evidence  given  or  discovered  pursuant  hereto,  shall  be
         maintained in confidence by all parties.

                  (g)   Continued   Performance.   The  fact  that  the  dispute
         resolution  procedures  specified in this Section 13 shall have been or
         may be invoked shall not excuse any


                                                     - 22 -

         rights to terminate this Agreement that may be available to any party.

         9.12  Governing  Law. This  Agreement may not be modified or terminated
orally, and shall be construed and interpreted  according to the internal law of

application of the laws of another jurisdiction.

         9.13 Counterparts. This Agreement may be executed by the parties hereto
in separate counterparts,  each of which when so executed and delivered shall be
an original,  but all such  counterparts  shall together  constitute one and the
same instrument.  Each counterpart may consist of a number of copies hereof each

contemplated hereunder.

         9.16 Sellers  Action.  Whenever in this Agreement the Sellers are given
the  discretion  to take or not to take any action,  the decision of the Sellers

                  (d) Each share of Newco stock  issued and  outstanding  at the

         into  and  exchanged  for  one  share  of the  stock  of the  Surviving

                  1.5 ISSUANCE OF HEALTHCARE SHARE CERTIFICATES.  At the Closing
each holder of a certificate or certificates representing shares of stock of the
HCA  Corporations  issued and  outstanding  at the  Effective  Time  (other than
treasury shares) shall surrender such certificate or certificates  duly endorsed
as HealthCare may require and shall receive in exchange  therefore a certificate
or certificates  representing 75 percent of the number of HealthCare Shares into
which  the  stock  of  the  HCA  Corporations  theretofore  represented  by  the
certificate  or  certificates  so  surrendered  shall  have been  converted  and
exchanged as provided in Section 1.4 hereof.  Certificates  for the remaining 25
percent balance of such HealthCare Shares (the "Retained  Shares") shall be held
and canceled or delivered as set forth in subsections 1.6(c), (d) or (e) below.

                  1.6      CLOSING BALANCE SHEET ADJUSTMENTS.

                  (a) Promptly after the Closing Date, the HCA Corporations will
         prepare balance sheets (the "Closing  Balance  Sheets") as of the close
         of business on the Closing  Date.  The Closing  Balance  Sheets will be
         prepared on an accrual  basis in  accordance  with  generally  accepted
         accounting principals except to the extent set forth in this Subsection
         1.6(a) and shall be  audited  by a  certified  public  accounting  firm
         approved  by  HealthCare.  The Closing  Balance  Sheets  shall  include
         accruals for  liabilities  as of the Closing  Date,  including  but not
         limited  to,  all  applicable  taxes  (including  income  taxes for the
         current period through Closing Date) and salaries,  wages, and benefits
         (including any outstanding  bonuses but excluding sick and vacation pay
         entitlements  as set forth on SCHEDULE 3.13 of the Disclosure  Schedule
         as defined in Section 6.5  hereof).  In preparing  the Closing  Balance
         Sheets,  (i) all hearing  aids ordered but not fitted to the patient as
         of the Closing Date will not be deemed sold and will not be included in
         sales  or  Closing  Balance  Sheet  accounts  receivable,  and (ii) all
         payments made by the HCA Corporations  with respect to such hearing aid
         orders shall be treated as prepaid  items.  The Closing  Balance Sheets
         shall be subject to review and reasonable approval by HealthCare.

                  (b) When the Closing  Balance  Sheets have been  prepared  and
         approved  by  HealthCare,   the  "Net  Current   Assets"  of  each  HCA
         Corporation shall be determined.



                                                     - 4 -




<PAGE>



         "Net  Current  Assets"  shall equal (i) cash,  money  market  accounts,
         accounts   receivable  (net  of  reasonable   provisions  for  doubtful
         accounts),  and  prepaid  expenses  less (ii) all  current  liabilities
         (including but not limited to trade accounts payable,  accrued expenses
         and supplier loans).

                  (c)  The HCA  Corporations  shall  have  "Target  Net  Current
Assets" as follows:

                           (i) Glendale - $95,000; (ii) Glendora -($11,000); and

                           (iii) Northridge - $417,200.

         To the extent  that the Net  Current  Assets of an HCA  Corporation  as
         shown on its Closing Balance Sheet exceed such HCA Corporation's Target
         Net  Current  Assets,   HealthCare   shall  either  (i)  issue  to  the
         Shareholders in the aggregate one HealthCare Share for each dollar (all
         dollar  references  herein are to United States dollars) of such excess
         or (ii) pay to the  shareholders  one  dollar  for each  dollar of such
         excess.  Such HealthCare  Shares or cash shall be apportioned among the
         Shareholders  pro rata based upon their  holdings  of the shares of the
         applicable  HCA  Corporation.  To the extent that an HCA  Corporation's
         Closing   Balance   Sheet  Net  Current   Assets  are  less  than  such
         corporation's  Target Net Current Assets,  the Shareholders shall elect
         either (i) to cancel  Retained  Shares in an aggregate  amount equal to
         one share for each dollar of the shortfall or (ii) to pay to HealthCare
         one dollar for each dollar of shortfall.  The Retained  Shares canceled
         or the repayment shall be apportioned  among the  Shareholders pro rata
         based  upon  each  Shareholder's  holdings  of the  shares  of the  HCA
         Corporation  with  respect  to  which   cancellation  or  repayment  is
         required.  Fractional  HealthCare  Shares  resulting  from  any  of the
         foregoing calculations shall be rounded up to the nearest whole share.

                  (d) At the Closing Date,  the HCA  Corporations  shall have no
         long term debt (with the  exception of a promissory  note of Northridge
         in the aggregate  principal  amount of $56,898 payable to Starkey Labs)
         or any other forms of  noncurrent  liabilities.  To the extent that the
         Closing  Balance Sheets  disclose any such long term debt or noncurrent
         liability  other than such  promissory  note,  Retained Shares shall be
         canceled in an  aggregate  amount equal to one share for each dollar of
         long  term  debt  or  noncurrent  liability  or,   alternatively,   the
         Shareholders  shall  pay  HealthCare  one  dollar  for each  dollar  of
         long-term debt or noncurrent liability. The Retained Shares canceled or
         amount repaid shall be proportioned among the Shareholders as set forth
         in Section (c) above.

                  (e) When the  requirements of Subsections  1.3(c) and (d) have
         been implemented,  an amount equal to 60 percent of the Retained Shares
         less any shares canceled  pursuant to Subsections  1.6(c) and (d) shall
         be  delivered  to the  Shareholders.  On the  200th day  following  the
         Closing Date (with the exception of those accounts receivable listed on
         SCHEDULE 1.6(E) for which the applicable collection period shall be 365
         days),  one  Retained  Share shall be  canceled  for each dollar of the
         accounts  receivable  shown on the Closing  Balance Sheet which remains
         uncollected in excess of the reserves for doubtful  accounts set out on
         the Closing Balance Sheet and any remaining balance of the Retained



                                                     - 5 -

         Shares  shall  be  delivered  pro rata to the  Shareholders,  provided,
         however,  that the Shareholders  may elect to reimburse  HealthCare one
         dollar for each dollar of uncollected  accounts receivable shown on the
         Closing Balance Sheets in lieu of such cancellation. Shareholders shall
         promptly  reimburse  Healthcare  one dollar for each dollar of accounts
         receivable  listed on SCHEDULE  1.6(E)  which  remains  uncollected  in
         excess  of the  reserve  for  doubtful  accounts  as of the  365th  day
         following the Closing Date.

         dispose of the stock of Newco;  or to cause Newco to sell or  otherwise
         dispose of any of the assets of the HCA  Corporations  acquired  in the
         transaction except for dispositions made

                  (e) The HealthCare  Shares issued in exchange for the stock of
         the  HCA  Corporations   hereunder,   including  all  Retained  Shares,
         constitutes less than 50 percent of both the voting power and the value
         of all HealthCare stock that will be outstanding  immediately following

                  (f)  HealthCare  has been  engaged in the active  conduct of a
         trade or business  that is  substantial  in  comparison  to each of the
         businesses  of the HCA  Corporations  for the  entire  36 month  period
         immediately preceding the Effective Time.

         4.6  DISCLOSURE.   To  HealthCare's  knowledge,  no  representation  or
warranty  by  HealthCare  in  this  Agreement  nor any  statement,  certificate,

hereof or otherwise approved in writing by HealthCare:

                  5.3(a) NO CHANGES.  The HCA  Corporations  will carry on their
         businesses diligently and in the same manner as heretofore and will not
         make or  institute  any  changes in their  methods of  purchase,  sale,
         management, accounting or operation.

                  5.3(b) MAINTAIN  ORGANIZATION.  The HCA Corporations  will use
         their best efforts to maintain,  preserve,  renew and keep in force and
         effect the existence, rights and franchises of the HCA Corporations and
         to preserve the business  organization of the HCA Corporations  intact,
         to keep available to HealthCare  the present  officers and employees of
         the HCA  Corporations,  and to preserve for  HealthCare  their  present
         relationships  with suppliers and customers and others having  business
         relationships with the HCA Corporations.

                  5.3(c) NO  BREACH.  The HCA  Corporations  will use their best
         efforts to avoid any act,  or any  omission  to act,  which may cause a
         breach of any  material  contract,  commitment  or  obligation,  or any
         breach of any representation,  warranty,  covenant or agreement made by
         the Shareholders.

                  5.3(d) NO MATERIAL  CONTRACTS.  No contract or commitment will
         be entered  into,  and no purchase of assets  (tangible or  intangible)
         will  be  made,  by  or on  behalf  of  the  HCA  Corporations,  except
         contracts,  commitments,  purchases  or sales which are in the ordinary
         course of business and consistent with past practice.

                  5.3(e) NO CORPORATE  CHANGES.  The HCA Corporations  shall not
         amend their Articles of  Incorporation or Bylaws or make any changes in
         their authorized or issued capital stock.

                  5.3(f)  MAINTENANCE OF INSURANCE.  The HCA Corporations  shall
         maintain  all of their  insurance  in effect  as of the date  hereof or
         replace such insurance with comparable  coverage and shall procure such
         additional  insurance as shall be reasonably requested by HealthCare at
         HealthCare's expense.

                  5.3(g)  MAINTENANCE OF PROPERTY.  The HCA  Corporations  shall
         use, operate,  maintain and repair all their assets and properties in a
         normal  business  manner  consistent  with the HCA  Corporations'  past
         practices.

                  5.3(h) INTERIM  FINANCIALS.  The HCA Corporations will provide
         HealthCare  with  interim  monthly   financial   statements  and  other
         management reports as and when they are available.

                  5.3(i) NO DIVIDENDS. The HCA Corporations shall not declare or
         pay any dividend (whether in cash, stock or property) or make any other
         distribution to the

         Shareholders,  except  for  (i)  the  repayment  of  loans  made by the
         Shareholders  to the HCA  Corporations  and (ii) the  distribution of a
         Dodge Caravan automobile to Carissa Bennett.

                  5.3(j)  COMPENSATION.  The HCA Corporations shall not increase
         the  compensation  or benefits of any of their  employees  nor make any
         other change in the terms of their employment.

         5.4  REIMBURSEMENT  OF SICK AND VACATION  PAY. In preparing the Closing
Balance  Sheets it has been  agreed  that no accrual  shall be made for sick and
vacation  pay   entitlements   for  employees  of  the  HCA   Corporations.   In
consideration of this exclusion,  the Shareholders  agree to reimburse Newco for
any sick or vacation pay payments Newco is required to make to former  employees
of the HCA  Corporations  who become  employees  of Newco as of the  Closing and
whose employment terminates for any reason within the first six months following
the  Closing  Date to the extent  such  payments  relate to  accruals of sick or
vacation pay prior to the Closing Date.

         5.5 PRESERVATION OF TAX-FREE  REORGANIZATION  STATUS.  The Shareholders
consent and agree as follows:

                  (a) There is no plan or intention by the Shareholders to sell,
         exchange or otherwise dispose of a number of HealthCare Shares received
         in  the  Merger  that  would  reduce  the  Shareholders'  ownership  of
         HealthCare  Shares to a number of shares having a value, as of the date
         of the  Merger,  of less  than 50  percent  of the  value of all of the
         formerly outstanding stock of the HCA Corporations as of the same date.

                  (b) Newco will  acquire at least 90 percent of the fair market
         value of the net  assets  and at least 70  percent  of the fair  market
         value  of the  gross  assets  held  by  each  of the  HCA  Corporations
         immediately prior to the Merger.

                  (c) The liabilities of the HCA  Corporations  assumed by Newco
         and  the  liabilities  to  which  the  transferred  assets  of the  HCA
         Corporations  are subject were incurred by the HCA  Corporations in the
         ordinary course of its business.

                  (d) The HCA Corporations,  and the Shareholders will pay their
         respective   expenses,   if  any,   incurred  in  connection  with  the
         transaction.

                  (e)  The HCA  Corporations  are not  investment  companies  as
         defined in Section 368(a)(2)(F)(iii) and (iv) of the Code.

                  (f) The HCA  Corporations  are not under the jurisdiction of a
         court in a Title 11 or  similar  case  within  the  meaning  of Section
         368(a)(3)(A) of the Code.

                  (g)  The  fair   market   value  of  the  assets  of  the  HCA
         Corporations  transferred  to Newco will equal or exceed the sum of the
         liabilities assumed by



                                                     - 19 -

         Newco, plus the amount of liabilities, if any, to which the transferred
         assets are subject.

6.       OTHER MATTERS

         6.1  EMPLOYMENT  AGREEMENT.  At the  Closing,  Newco  and  each  of the
Shareholders shall execute and deliver counterparts of Employment  Agreements in
the form attached hereto as SCHEDULES 6.1-A (GREGORY J. FRAZER);  6.1-B (CARISSA
BENNETT); AND 6.1-C (JAMI TANIHANA).

         6.2      SECURITIES LAWS.

                  6.2(a) INVESTMENT REPRESENTATIONS.  The Shareholders represent
         to HealthCare as follows:

                  (i) The  HealthCare  Shares are being  acquired  for their own
         accounts  and  for  investment  only,  and  not  with  a  view  to  the
         distribution  of all or any  part  of the  HealthCare  Shares,  and the
         acquisition  of the  HealthCare  Shares by the  Shareholders  and their
         continued  holding  thereof  as may be  required  by law and the  terms
         hereof are consistent with their respective financial positions.

                  (ii) The Shareholders have had access to complete  information
         regarding  the  business  and  finances  of  HealthCare,  have  met and
         discussed the business and finances of HealthCare  with its  management
         employees to the extent they deem necessary,  and have received,  read,
         and understood the contents of the Healthcare Capital Corp. Preliminary
         Prospectus  dated  July  __,  1996;  draft  dated  July 12,  1996  (the
         "Prospectus").

                  6.2(b)  LIMITATIONS ON TRANSFER.  Except as expressly provided
         in this Agreement,  the Shareholders shall not, directly or indirectly,
         offer or sell,  pledge,  transfer,  or otherwise  dispose of all or any
         portion  of the  HealthCare  Shares,  or  solicit  any  offer  to  buy,
         purchase,  or otherwise  acquire or take a pledge of all or any portion
         of the  HealthCare  Shares,  except (A) in the manner and to the extent
         described  in  (i)  a  registration   statement  in  effect  under  the
         Securities Act of 1933 (the "Act")  covering the HealthCare  Shares and
         as to which a prospectus  meeting the  requirements  of the Act is duly
         delivered  or (ii) an opinion of counsel  for the  Shareholders,  which
         opinion  is  in  form  and  substance   satisfactory   to  counsel  for
         HealthCare,  to the effect  that such  proposed  offer,  sale,  pledge,
         transfer,  or other  disposition  of HealthCare  Shares may lawfully be
         made without such  registration  and delivery or (B) pursuant to trades
         made on the Alberta Stock Exchange  ("ASE") after 90 days following the
         Closing  Date  pursuant to Rule 904 of  Regulation S under the Act. The
         Shareholders   acknowledge   that  they  have  consulted  with  counsel
         concerning the limited  availability  of exemptions  from  registration
         under the Act and they  understand  that they (i) may bear the economic
         risk of investment in the HealthCare Shares for an indefinite period of
         time because the HealthCare  Shares have not been registered  under the
         Act  and,  therefore,  cannot  be sold  unless  they  are  subsequently
         registered under the Act or an exemption from such



                                                     - 20 -




<PAGE>



         registration,  such as that  contained in Rule 904 is  available,  (ii)
         HealthCare is not obligated to register the HealthCare Shares under the
         Act, (iii) that absent  registration,  the HealthCare Shares ordinarily
         may not be sold in the United  States for at least two years  after the
         Closing Date and then only in  accordance  with Rule 144 under the Act,
         and  (iv)  the  HealthCare  Shares  may  not be  sold,  transferred  or
         otherwise  disposed of in the  province of Alberta,  Canada,  or traded
         through the facilities of the ASE for a period of 90 days following the
         Closing Date.

                  6.2(c) LEGENDS ON CERTIFICATES.  Certificates representing the
         HealthCare Shares shall be endorsed with legends,  (i) substantially in
         the form set forth in SCHEDULE 6.2(D)(I) hereto, and (ii) to the effect
         that the  HealthCare  Shares  may not be traded  in Canada  for 90 days
         following  the Closing Date.  HealthCare  need not recognize any person
         other  than  the  Shareholders  as  having  any  interest  in or to the
         HealthCare  Shares unless the acquisition  thereof shall have been made
         in  compliance  with  Subsection  6.2(b)  above.  HealthCare  may issue
         appropriate  stop transfer  instructions  to the transfer agent for the
         HealthCare  Shares to prevent  transfers  in  violation  of  Subsection
         6.2(b) hereof.

                  6.2(d)  REMOVAL  OF  LEGENDS.   (i)  At  any  time  while  the
         HealthCare Shares are registered under the Act,  HealthCare shall, upon
         written  request,  cause the  certificates  representing the HealthCare
         Shares  to be  reissued  free of all  legends  and  withdraw  all  stop
         transfer instructions. Upon the termination of any such registration, a
         Shareholder  who owns  HealthCare  Shares  represented by a certificate
         without such legends, shall, upon written request, promptly return such
         certificate to HealthCare  for reissue for a certificate  endorsed with
         the legends  specified in, and otherwise  subject to, the provisions of
         Subsection  6.2(c).  Three years after the Closing  Date,  HealthCare's
         right to request the return of unlegended  certificates  for previously
         registered HealthCare Shares shall terminate and HealthCare shall, upon
         written request of the Shareholders, cause any certificates bearing one
         or more  legends to be reissued  free of such  legends and withdraw all
         stop transfer instructions, provided that Rule 144(k) under the Act, or
         a comparable rule, is in effect in  substantially  its present form and
         the  Shareholders  furnish  to  HealthCare  evidence   satisfactory  to
         HealthCare  and its  counsel  that they meet the  requirements  of such
         rule.

                  (ii)  HealthCare   shall,   upon  written  request,   cause  a
         certificate  representing all or a portion of the HealthCare  Shares to
         be reissued  free of all legends and shall  withdraw all stop  transfer
         instructions  upon the provision by a Shareholder  of a declaration  to
         The R-M Trust Company as transfer agent in  substantially  the form set
         forth in EXHIBIT 6.2(D)(II) hereto.

         6.3      REGISTRATION UNDERTAKING.

                  (a) HealthCare  agrees that, if at any time from and after the
         Closing Date and before the second  anniversary of such date, the board
         of directors of HealthCare shall authorize the filing of a registration
         statement  under the Act to permit the trading of HealthCare  Shares in
         the United States, HealthCare will (i) promptly notify the



                                                     - 21 -




<PAGE>



         Shareholders  that such  registration  statement will be filed and that
         the HealthCare  Shares which are then held by the Shareholders  will be
         included in such registration  statement at their request, (ii) subject
         to the last sentence of this  subsection  (a), cause such  registration
         statement to cover all HealthCare Shares which it has been so requested
         to include by the  Shareholders,  provided such request is delivered to
         HealthCare  not later than 20 days  after  such  notice is given to the
         Shareholders  and  specifies  the  number  of  HealthCare  Shares to be
         included in the proposed  registration,  (iii) use  reasonable  efforts
         subject to market  conditions to cause such  registration  statement to
         become  effective  and remain  effective and current for such period as
         may  be   necessary  to  permit  the   underwriters   to  complete  the
         distribution of the securities  covered by the registration  statement,
         if such  offering is an  underwritten  offering,  or, if not,  for such
         period,  not  in  excess  of 90  days,  as  may be  necessary  for  the
         Shareholders to effect a proposed sale or other distribution,  and (iv)
         take all  other  action  necessary  under any  federal  or state law or
         regulation  of  any  governmental   authority  (other  than  the  state
         securities  or blue sky laws) to permit  the  shares  included  in such
         registration  statement  to be sold or  otherwise  disposed of and will
         maintain  such  compliance  with  each such  federal  and state law and
         regulation of governmental  authority for the period  necessary for the
         underwriters  or the  Shareholders,  as the case may be, to effect  the
         proposed  sale or  other  disposition.  Notwithstanding  the  foregoing
         provisions,  if the registration  statement  relates to an underwritten
         offering of HealthCare Shares and the managing underwriter shall inform
         in writing  HealthCare  and the  Shareholders  and any other holders of
         HealthCare  Shares  requesting  such  registration  that  the  managing
         underwriter believes that the number of shares requested to be included
         in such registration would materially,  adversely affect its ability to
         effect such offering, then HealthCare will include in such registration
         the number of HealthCare  Shares which  HealthCare is so advised can be
         sold in (or during the time of) such  offering as follows:  first,  all
         shares  proposed by  HealthCare  to be sold for its own  account,  and,
         second,  such  HealthCare  Shares  requested  to be  included  in  such
         registration,  pro  rata  by the  Shareholders  and  other  holders  of
         HealthCare  Shares on the basis of the number of  HealthCare  Shares so
         proposed to be sold and so requested to be included; PROVIDED, HOWEVER,
         that HealthCare shall be obligated to register any HealthCare Shares so
         excluded from the  registration  statement  pursuant to a  registration
         statement  filed  90 days  after  the  effectiveness  of  such  initial
         registration  statement  or  such  greater  number  of  days  as may be
         specified  in  "lock-up"  agreements  entered  into  with the  managing
         underwriter.

                  (b) Whenever HealthCare is required pursuant to the provisions
         of this  Section  6.3 to include  HealthCare  Shares in a  registration
         statement,  HealthCare  shall (i)  furnish  each  Shareholder  and each
         underwriter of such HealthCare Shares with such copies of a prospectus,
         including the preliminary  prospectus,  conforming to the Act (and such
         other  documents  as each  Shareholder  and each such  underwriter  may
         reasonably  request) in order to facilitate the sale or distribution of
         HealthCare  Shares,  (ii) use its best  efforts to  register or qualify
         such  HealthCare  Shares  under  the  blue  sky  laws  (to  the  extent
         applicable) of such  jurisdiction or  jurisdictions as the Shareholders
         and each  underwriter of HealthCare  Shares being sold shall reasonably
         request and (iii) take such other



                                                     - 22 -

         actions  as may be  reasonably  necessary  or  advisable  to enable the
         Shareholders   and  such   underwriters   to  consummate  the  sale  or
         distribution  in such  jurisdiction  or  jurisdictions  in  which  such
         holders shall have reasonably  requested that the HealthCare  Shares be
         sold.  Each  Shareholder  shall  furnish to  HealthCare in writing such
         information relating to themselves as HealthCare may reasonably request
         in connection with the preparation of such registration statement.

                  (c) HealthCare  shall pay all expenses  incurred in connection
         with any  registration  or other action  pursuant to the  provisions of
         this Section 6.3,  other than  underwriting  discounts  and  applicable
         transfer taxes relating to the HealthCare  Shares sold by  Shareholders
         and attorney fees and expenses of the Shareholders.

                  (d)  HealthCare  agrees to  indemnify  and hold  harmless  the
         Shareholders  from and  against any and all  losses,  claims,  damages,
         liabilities or actions, joint or several, to which the Shareholders may
         become subject under the Act for any legal or other expenses (including
         the cost of any  investigation  and  preparation)  incurred  by them in
         connection with any litigation or threatened litigation, whether or not
         resulting in any  liability,  but only insofar as such losses,  claims,
         damages,  liabilities  or actions arise out of, or are based upon,  (i)
         any untrue  statement or alleged  untrue  statement of a material  fact
         contained in any  registration  statement  pursuant to which HealthCare
         Shares   were   registered   under  the  Act   (hereinafter   called  a
         "Registration  Statement"),   any  preliminary  prospectus,  the  final
         prospectus  or  any   amendment  or  supplement   thereto  (or  in  any
         application or document filed in connection  therewith) or any document
         filed by HealthCare in any jurisdiction in order to register or qualify
         the HealthCare Shares under the securities laws thereof or the omission
         or alleged  omission to state  therein a material  fact  required to be
         stated  therein or necessary  to make the  statements  therein,  in the
         light of the circumstances  under which they were made, not misleading,
         or (ii) the employment by HealthCare of any device,  scheme or artifice
         to defraud,  or the  engaging  by  HealthCare  in any act,  practice or
         course  of  business  which  operates  or would  operate  as a fraud or
         deceit,  or any conspiracy with respect  thereto,  in which  HealthCare
         shall  participate,  in connection with the issuance and sale of any of
         the  HealthCare  Shares;  PROVIDED,  HOWEVER  that  (i)  the  indemnity
         agreement  contained  in this  Subsection  (d) shall not  extend to any
         Shareholder in respect of any such losses, claims, damages, liabilities
         or actions  arising out of, or based upon any such untrue  statement or
         alleged untrue statement,  or any such omission or alleged omission, if
         such  statement or omission was based upon and made in conformity  with
         information  furnished  in  writing  to  HealthCare  by  a  Shareholder
         specifically  for  use in  connection  with  the  preparation  of  such
         Registration   Statement,   any  final   prospectus,   any  preliminary
         prospectus  or any such  amendment  or  supplement  thereto  (or in any
         application  or document  filed in  connection  therewith)  or document
         filed  in  any  jurisdiction  in  order  to  register  or  qualify  the
         HealthCare Shares under the securities laws thereof.  HealthCare agrees
         to pay any legal and

         other  expenses for which it is liable under this  Subsection  (d) from
         time to time  (but not more  frequently  than  monthly)  within 30 days
         after its receipt of a bill therefor.

                  (e)  Each  Shareholder,   severally  and  not  jointly,   will
         indemnify and hold harmless HealthCare, its directors, its officers who
         shall have signed the Registration  Statement and each person,  if any,
         who controls  HealthCare within the meaning of Section 15 of the Act to
         the same extent as the foregoing indemnity from HealthCare, but in each
         case to the extent,  and only to the extent,  that any  statement in or
         omission from or alleged omission from such Registration Statement, any
         final  prospectus,  any  preliminary  prospectus  or any  amendment  or
         supplement  thereto  (or  in  any  application  or  document  filed  in
         connection therewith) or document filed in any jurisdiction in order to
         register or qualify the  HealthCare  Shares under the  securities  laws
         thereof was made in reliance upon  information  furnished in writing to
         HealthCare by such Shareholder  specifically for use in connection with
         the preparation of the Registration Statement,  any final prospectus or
         the preliminary  prospectus or any such amendment or supplement thereto
         (or in any  application or document  filed in connection  therewith) or
         document filed in any  jurisdiction in order to register or qualify the
         HealthCare Shares under the securities laws thereof; PROVIDED, HOWEVER,
         that the obligation of any  Shareholder to indemnify  HealthCare  under
         the  provisions of this  Subsection (e) shall be limited to the product
         of the number of HealthCare  Shares being sold by the  Shareholder  and
         the market  price of  HealthCare  Shares on the date of the sale to the
         public of these HealthCare  Shares.  Each Shareholder agrees to pay any
         legal and other  expenses  for  which he or she is  liable  under  this
         Subsection (e) from time to time (but not more frequently than monthly)
         within 30 days after receipt of a bill therefor.

                  (f) If any  action is  brought  against a person  entitled  to
         indemnification  pursuant to the foregoing  Subsections (d) and (e) (an
         "indemnified  party")  in  respect  of which  indemnity  may be  sought
         against a person granting  indemnification  (an  "indemnifying  party")
         pursuant to such Subsections (d) and (e), such indemnified  party shall
         promptly notify such indemnifying  party in writing of the commencement
         thereof;  but the omission so to notify the  indemnifying  party of any
         such action shall not release the indemnifying party from any liability
         it,  he or she may have to such  indemnified  party  otherwise  than on
         account of the indemnity agreement contained in Subsections (d) and (e)
         of this  Section  6.3.  In case any such  action is brought  against an
         indemnified  party and it, he or she notifies an indemnifying  party of
         the commencement  thereof, the indemnifying party against which a claim
         is to be made will be entitled to  participate  therein at its,  his or
         her own  expense  and,  to the extent  that it, he or she may wish,  to
         assume at its, his or her own expense the defense thereof, with counsel
         reasonably  satisfactory to such indemnified party; PROVIDED,  HOWEVER,
         that  (i) if the  defendants  in  any  such  action  include  both  the
         indemnified party and the indemnifying party and the indemnifying party
         shall have reasonably concluded



                                                     - 24 -

         based upon advice of counsel that there may be legal defenses available
         to it, he or she and/or other  indemnified  parties which are different
         from or additional to those  available to the  indemnified  party,  the
         indemnified  party shall have the right to select  separate  counsel to
         assume such legal  defenses and otherwise to participate in the defense
         of such action on behalf of such indemnified  party or parties and (ii)
         in any event,  the indemnified  party shall be entitled to have counsel
         chosen by such indemnified party  participate in, but not conduct,  the
         defense  at the  expense of the  indemnifying  party.  Upon  receipt of
         notice from the indemnifying  party to such  indemnified  party of its,
         his or her  election  so to  assume  the  defense  of such  action  and
         approval by the indemnified  party of counsel,  the indemnifying  party
         will not be liable to such indemnified party under this Section 6.3 for
         any legal or other expenses  subsequently  incurred by such indemnified
         party in connection with the defense thereof unless (i) the indemnified
         party  shall  have  employed  such  counsel  in  connection   with  the
         assumption of legal defenses in accordance with proviso (i) to the next
         preceding sentence (it being understood, however, that the indemnifying
         party shall not be liable for the  expenses  of more than one  separate
         counsel),  (ii) the indemnifying  party shall not have employed counsel
         reasonably  satisfactory  to the  indemnified  party to  represent  the
         indemnified party within a reasonable time after notice of commencement
         of the  action  or (iii) the  indemnifying  party  has  authorized  the
         employment of counsel for the  indemnified  party at the expense of the
         indemnifying  party. An indemnifying  party shall not be liable for any
         settlement  of any action or  proceeding  effected  without its written
         consent.

                  (g) In order to provide for just and equitable contribution in
         circumstances  in  which  the  indemnity   agreement  provided  for  in
         Subsections  (d) and  (e) of  this  Section  6.3 is  unavailable  to an
         indemnified  party in  accordance  with its terms,  HealthCare  and the
         Shareholders shall contribute to the aggregate losses,  claims, damages
         and  liabilities,   of  the  nature   contemplated  by  said  indemnity
         agreement,  incurred  by  HealthCare  and  the  Shareholders,  in  such
         proportions  as  are  appropriate  to  reflect  the  relative  benefits
         received by HealthCare  and the  Shareholders  from any offering of the
         HealthCare Shares;  PROVIDED,  HOWEVER,  that if such allocation is not
         permitted by applicable law or if the indemnified  party failed to give
         the notice required under  Subsection (f) of this Section 6.3, then the
         relative fault of HealthCare and the  Shareholders  in connection  with
         the  statements  or omissions  which  resulted in such losses,  claims,
         damages and  liabilities  and other relevant  equitable  considerations
         will be considered together with such relative benefits.

                  (h) The respective  indemnity and  contribution  agreements by
         HealthCare and the Shareholders in Subsections (d), (e), (f) and (g) of
         this  Section 6.3 shall remain  operative  and in full force and effect
         regardless  of (i)  any  investigation  made by any  Shareholder  or by
         HealthCare or any  controlling  person of HealthCare or any director or
         any  officer of  HealthCare,  (ii)  payment  for any of the  HealthCare
         Shares or (iii) any termination of this



                                                     - 25 -

         Agreement, and shall survive the delivery of the HealthCare Shares, and
         any successor of HealthCare,  or of any  Shareholder,  or of any person
         who controls  HealthCare,  as the case may be, shall be entitled to the
         benefit of such respective indemnity and contribution  agreements.  The
         respective indemnity and contribution  agreements by HealthCare and the
         Shareholders  contained in  Subsections  (d),  (e), (f) and (g) of this
         Section 6.3 shall be in addition to any liability which  HealthCare and
         the Shareholders may otherwise have.

                  (i) If, after the date hereof,  HealthCare issues unregistered
         HealthCare  Shares and provides to the  recipient  registration  rights
         which are more  favorable than those  afforded to the  Shareholders  in
         this Section 6.3, the  Shareholders  shall  without  further  action be
         entitled to the benefit of such more favorable registration provision.

         6.4 NASDAQ LISTING.  HealthCare  intends to apply for and shall use its
best  efforts  to obtain  not later  than six  months  after  the  Closing  Date
quotation of HealthCare  Shares on the National Market System tier of The Nasdaq
Stock Market.

         6.5 DISCLOSURE SCHEDULE. The "Disclosure Schedule" has been compiled in
a bound volume executed by the  Shareholders and dated and delivered on the date
of this Agreement. The Disclosure Schedule includes a table of contents or index
of all the information and documents contained therein.

         6.6 RELEASE OF SHAREHOLDERS.  The Shareholders  have provided  personal
guarantees or have otherwise become  individually liable with respect to certain
leases, line of credit agreements,  purchase  agreements with manufacturers,  or
other agreements for the benefit for the HCA  Corporations,  including,  without
limitation,  those described on SCHEDULE 6.4 of the Disclosure  Schedule.  After
the Closing Date,  HealthCare will use its best efforts to obtain the release of
the Shareholders from all such personal liabilities. To the extent that any such
release cannot be obtained,  HealthCare will indemnify and hold the Shareholders
harmless with respect to any loss, cost, or expense  Shareholders may incur as a
result of not being released.

         6.7 SHAREHOLDER  LOANS. As of the date hereof, the HCA Corporations are
indebted  to the  Shareholders  as set forth on SCHEDULE  6.5 of the  Disclosure
Schedule.   Notwithstanding   any  other  provision  of  this   Agreement,   the
Shareholders  shall have the option to (i) contribute  such  indebtedness to the
capital of the HCA  Corporations  on or prior to the Closing Date, or (ii) cause
the  HCA  Corporations  to  repay  such  indebtedness  to  the  extent  the  HCA
Corporations   have  funds  available  for  such  purpose.   In  the  event  any
indebtedness  of  the  HCA  Corporations  to  the  Shareholders  remains  unpaid
following  the  Closing  Date,  HealthCare  shall  cause  Newco  to  repay  such
indebtedness in full within 45 days of the Closing Date.

         6.8      COVENANTS OF HEALTHCARE.

                  (a)  Following  the  Merger,  Newco will not issue  additional
         shares of its stock that would result in HealthCare  losing  control of
         Newco within the meaning of Section 368(c) of the Code.

                  (b)  Following  the Merger,  Newco will  continue the historic
         business of each of the HCA  Corporations or use a significant  portion
         of each of the HCA Corporations' business assets in a business.

                  (c)  HealthCare  will comply,  and will cause Newco to comply,
         with the reporting  requirements set forth in ss.  1.367(a)-3T(c)(4) of
         the U.S. Treasury Regulations following consummation of the Merger.

                  (d)  HealthCare  and Newco will  treat the Merger as  tax-free
         reorganizations  of the HCA  Corporations  for U.S. tax purposes on all
         tax returns filed by them in the United States,  and neither HealthCare
         nor Newco will take any action  inconsistent with such treatment of the
         Merger,  or which would cause the Merger to fail to qualify as tax-free
         reorganizations.

         6.9  REDEMPTION  OF HEALTHCARE  SHARES.  As of the last business day of
each calendar  quarter for the 20 calendar  quarters  immediately  following the
Closing Date, the  Shareholders  shall have a right to tender to HealthCare,  in
the  numbers  set  forth  below,  HealthCare  Shares  they own,  in which  event
HealthCare  shall  redeem from the  Shareholders  and pay for within 20 business
days of the end of the applicable quarter the number of shares tendered at $1.67
(U.  S.) per  HealthCare  Share.  The  number of  HealthCare  Shares  which each
Shareholder  shall be  entitled to tender for  redemption  as of the end of each
calendar quarter is as follows:

         SHAREHOLDER                                            NUMBER OF SHARES

         Gregory J. Frazer                                           1,800
         Carissa Bennett                                             6,600

The Shareholders'  rights to tender HealthCare Shares shall be noncumulative and
to the extent not  exercised as of the end of any calendar  quarter shall expire
and thereafter be of no further force and effect.

or breach of any representation or warranty of the Shareholders  contained in or

Shareholders contained in this Agreement.  As used in this Section 9.1, the term
"Claim"  shall  include all losses,  damages,  judgments,  awards,  settlements,

or event  which  may give  rise to a matter  for  which  indemnification  may be
sought; provided that the failure of any indemnified party to give timely notice
shall not affect the rights to  indemnification  hereunder  except to the extent
that the indemnifying party  demonstrates  actual damage caused by such failure.
If any lawsuit or enforcement  action is filed against any party entitled to the
benefit of indemnity hereunder,  and if the indemnifying party shall acknowledge
in  writing  to the  indemnified  party  that the  indemnifying  party  shall be
obligated  under the terms of its indemnity  hereunder in  connection  with such
lawsuit,  action or claim, then the indemnifying party shall be entitled,  if it
so elects,  to take control of the defense and  investigation of such lawsuit or
action and to employ and engage attorneys of its own choice to handle and defend
the same, at the  indemnifying  party's cost, risk and expense provided that the
indemnifying  party and its counsel  shall  proceed with  diligence  and in good
faith with  respect  thereto.  The  indemnified  party  shall  cooperate  in all
reasonable  respects  with the  indemnifying  party  and such  attorneys  in the
investigation,  trial and  defense  of such  lawsuit  or action  and any  appeal
arising therefrom; provided, however, that the indemnified party may, at its own
cost,  participate  in the  investigation,  trial and defense of such lawsuit or
action and any appeal arising therefrom.

         13.1 ARBITRATION.  Any dispute,  controversy or claim arising out of or
relating to this Agreement or the  performance by the parties of its terms shall

Notwithstanding the foregoing,  HealthCare, in its discretion,  apply to a court
of competent  jurisdiction for equitable relief from any violation or threatened
violation  of the  covenants  of the  Shareholders  under  Section  5.1 of  this
Agreement.

         13.2 ARBITRATORS.  If the matter in controversy  (exclusive of attorney
fees and expenses) shall appear,  as at the time of the demand for  arbitration,
to exceed $50,000, then the panel to be appointed shall consist of three neutral

         13.3  PROCEDURES;   NO  APPEAL.  The  arbitrator(s)  shall  allow  such
discovery as the arbitrator(s) determine appropriate under the circumstances and
shall resolve the dispute as  expeditiously  as  practicable,  and if reasonably
practicable,  within  120 days after the  selection  of the  arbitrator(s).  The
arbitrator(s)  shall give the parties  written notice of the decision,  with the
reasons  therefor  set out,  and  shall  have  thirty  (30) days  thereafter  to
reconsider  and modify such  decision  if any party so requests  within ten (10)

under legal or equitable  principles,  including interim or preliminary  relief,
and to allocate  responsibility  for the costs of the  arbitration  and to award

appropriate by the arbitrator(s).

         13.5  ENTRY OF  JUDGMENT.  Judgment  upon  the  award  rendered  by the
arbitrator(s)  may be entered in any court having in personam and subject matter
jurisdiction.  The Shareholders and HealthCare  hereby submit to the in personam

confirming any such award and entering judgment thereon.

expenses less Trade Payables.

                  (i) As promptly as practicable  following the Closing,  but in
no event later than 45 days thereafter (the "45-Day  Period"),  Buyer and Seller
shall cooperate to prepare a mutually  agreeable  computation of the Net Working

Seller,  afford Seller  access to the books and records of the Midwest  Division
and, upon reasonable prior notice and without  unreasonable  disruption,  to the
employees  of Buyer,  and  afford  Seller  with the  reasonable  opportunity  to
participate  in and consult with Buyer,  in connection  with the  preparation by
Buyer of the Statement of Net Working Capital.

                  (e) On the fifteenth day after the date on which the Statement
of Closing  Working  Capital shall have been  completed (or such earlier date as
such statement is mutually  agreed upon by Seller and Buyer in writing),  if the
Net  Working  Capital  shown on the  Statement  of Net  Working  Capital  is not
disputed by Seller pursuant to section 1.4(f) hereof,  (i) in the event that the
Net Working Capital exceeds  $50,000,  then Buyer shall pay to Seller the amount
by which the Net Working Capital exceeds $50,000,  or (ii) in the event that the
Net Working  Capital is less than  $50,000  (the amount by which the Net Working
Capital is less than $50,000, the "Negative Amount"), then Seller shall promptly
remit to Buyer an amount equal to the Negative Amount;

                  (f) If Buyer and Seller are unable to mutually  agree upon the
Statement of Net Working Capital within the 45-Day Period,  all disputed matters
not so resolved  shall be  submitted  to  arbitration.  One-half of all fees and

         1.5 ALLOCATION OF PURCHASE PRICE. The Purchase Price shall be allocated
among the  Transferred  Assets being sold  hereunder  in the manner  required by
Treasury  Regulation ss.  1.1060-1T and shall be mutually agreed among Buyer and
Seller.  Buyer will submit to Seller a proposed  allocation  within  ninety (90)
days from the date  hereof.  Buyer and  Seller  shall  thereafter  agree upon an
allocation (the "Proposed  Allocation").  Buyer and Seller agree that: except as
otherwise required by law, (a) the Proposed Allocation shall be binding on Buyer
and  Seller for all  federal,  state and local tax  purposes,  and (b) Buyer and
Seller shall file with their  respective  federal income tax returns  consistent
IRS Form 8594-Asset  Acquisition  Statements  under Section 1060,  including any
required amendments thereto which shall reflect the allocations set forth in the
Proposed  Allocation.  Seller  agrees to assist  Buyer in  obtaining  accounting
treatment  to  facilitate  a step-up  in basis on the  Transferred  Assets.  The
parties



                                                     - 5 -

<PAGE>



acknowledge  that the  allocation  of the  Purchase  Price  provided  for in the
Proposed Allocation will be reasonable.

         1.6  TRANSFER  TAXES.  Buyer and Seller  shall each pay one-half of all
local,  city,  municipal,  county,  state and federal  sales and transfer  taxes
incurred,  if any, in  connection  with the  transactions  contemplated  by this
Agreement.  Each party  shall in a timely  manner  sign and swear to any return,
certificate,  questionnaire  or  affidavit  as to matters  within its  knowledge
required in connection with the payment of any such tax.

         1.7 EMPLOYEES.  In addition to the Excluded  Liabilities,  Seller shall
retain all liabilities and claims for salary,  bonuses,  back-pay,  commissions,
benefits or other  compensation based claims of employees or former employees of
Seller arising prior to the Closing, which are not specifically assumed by Buyer
hereunder.  Buyer shall offer  employment  to all  employees of Seller  employed
exclusively  in  connection  with  the  Midwest  Division,  on  such  terms  and
conditions as determined by Buyer in its sole discretion.

         1.8 ASSETS AFTER THE CLOSING.  If Seller  shall,  at any time after the
Closing,  receive any Transferred Assets (including any returned products or any
payments) related to the Midwest Division, it shall promptly deliver such assets
to Buyer.

         1.9 BULK TRANSFER LAWS.  Buyer hereby waives  compliance by Seller with
any applicable bulk sale or bulk transfer laws of any jurisdiction in connection
with the sale of the  Transferred  Assets  to  Buyer;  PROVIDED,  HOWEVER,  that
nothing in this Section 1.9 shall be construed (a) as an  indication  that Buyer
or Seller has determined that any bulk sale or transfer law is applicable to the
sale of the Transferred Assets or (b) to undermine Seller's absolute  obligation
to pay any liabilities retained by it hereunder.

         1.10 CLOSING.  The closing of the transaction  provided for herein (the
"Closing")  shall be deemed to have  occurred  as of the  close of  business  on
October 31, 1996. Notwithstanding the foregoing, HealthCare shall have the right
to extend the Closing for up to ninety (90) days if, in its judgment, it becomes
necessary to do so as a result of requirements  of the Province of Alberta,  the
Alberta Stock Exchange (the "ASE"),  United States, state of Washington or state
of Delaware securities laws,  regulations or rules. The Closing shall take place
at the offices of HealthCare at 111 S.W.  Fifth  Avenue,  Suite 2390,  Portland,
Oregon 97204, at such time as the parties shall mutually agree.

         2.6 FINANCIAL  STATEMENTS AND BOOKS AND RECORDS.  Seller has heretofore
delivered to Buyer the following  financial  statements of Hearing Health or the
Midwest Division  including balance sheets and related statements of income (the
"Financial Statements"):

                  (a) Financial Statements for Hearing Health's 1994 fiscal year
         and the Midwest  Division's 1995 and 1996 fiscal years (except that the

         flow); and

                  (b) Financial  statements for the Midwest  Division's  interim
         period ended September 30, 1996 (excluding statements of cash flow).

The Financial  Statements are correct and complete in all material  respects and
fairly  present the  financial  condition  of the Midwest  Division at the dates
indicated and results of its  operations  and changes in its financial  position
for the periods then ended in  accordance  with  generally  accepted  accounting
principles.  The books and records of the Midwest Division accurately reflect in
all material respects the transactions to which the Midwest Division is, or was,
a party or by which  properties  or assets  relating to the Midwest  Division of
Seller are, or were,  subject or bound.  The books and records have been kept in
accordance with the normal business practices of the Midwest Division.

         2.7 NO MATERIAL  ADVERSE CHANGE.  Since  September 30, 1996,  there has
been no  material  adverse  change  in the  business,  operations  or  condition
(financial  or  otherwise)  of the Midwest  Division of Seller  excluding  those
changes that result from factors  affecting  the industry  generally or that are
caused by  general  economic  conditions  and  Seller  does not know of any such
change,  excluding such changes that result from factors  affecting the industry
generally or that are caused by general economic conditions,  that is threatened

the ability of Seller to  consummate  the  transactions  contemplated  hereunder
(henceforth, a "Material Adverse Effect").

         2.8 NO UNDISCLOSED  LIABILITY.  Except (a) as described to Buyer on the
schedules hereto as an item which can be reasonably  construed as a liability or
obligation or (b) items not required to be disclosed on the schedules  hereto by
reason of  exceptions,  exclusions,  or other  qualifications  contained  in the

material liabilities or obligations of any nature (absolute, accrued, contingent
or  otherwise)  which are not  properly  reflected  or  reserved  against in the
Financial  Statements  (except for  liabilities or  obligations  which have been
incurred in the  ordinary  course of business  since the date of the most recent
Financial Statement) in a manner consistent with past practice; and the reserves
reflected in the Financial Statements are adequate, appropriate and reasonable.

         2.9  LITIGATION.  Except as set  forth on  Schedule  2.9,  there are no
outstanding  orders,  judgments,  injunctions,  awards or  decrees of any court,

are covered by insurance)  against Seller relating to the Midwest  Division,  or
any  officer,  director or employee of Seller other than any such items which do
not and will not  materially  adversely  affect the  business or  operations  of
Midwest Division of Seller, the Transferred Assets or the Assumed Liabilities.

         2.10     COMPLIANCE WITH LAWS.

                  (a) COMPLIANCE. Seller in connection with the Midwest Division
(including  each  and  all  of the  Midwest  Division's  operations,  practices,
properties and assets) is in material  compliance  with all applicable  federal,
state,  local and  foreign  laws,  ordinances,  orders,  rules  and  regulations
(collectively,  "Laws"),  including,  without  limitation,  those  applicable to
discrimination in employment,  occupational safety and health,  trade practices,
environmental protection,  competition and pricing, product warranties,  zoning,
building and sanitation, employment, retirement and labor relations, and product
advertising  except to the  extent any  noncompliance  would not have a material
adverse effect upon the assets or the businesses of Seller taken as a whole.  To
the  knowledge  of Seller,  Seller has not received  notice of any  violation or
alleged  violation of, and is not subject to any material  liability for past or
continuing  violation of, any Laws. All reports and returns required to be filed
by Seller with any governmental authority have been filed, and were accurate and
complete  when filed except to the extent  failure to file or any  deficiency in
accuracy  or  completeness  would not have a material  adverse  effect  upon the
assets or the business of Seller taken as whole.

                  (b) LICENSES AND  PERMITS.  Seller has obtained all  licenses,
permits,  approvals,   authorizations  and  consents  of  all  governmental  and
regulatory  authorities  and all  certification  organizations  required for the
conduct of its Midwest  Division (as presently  conducted)  except to the extent
failure to do so would not have a material adverse effect upon the assets or the
businesses of Midwest Division of Seller taken as a whole. Seller (including its
operations,  properties and assets) is and has been in compliance  with all such
permits and licenses,  approvals,  authorizations  and  consents,  except to the
extent any  noncompliance  would not have a  material  adverse  effect  upon the
assets or the businesses of Seller taken as a whole.

         2.11  ENVIRONMENTAL  COMPLIANCE.  Seller has not  received  any written
communication  from any  environmental  agency with  respect to the  Transferred
Assets or with  respect to the  Business  Premises and Seller has since June 28,
1994,  and has at all  times  thereafter,  operated  the  Midwest  Division,  in
material compliance with, or otherwise ceased any material  non-compliance with,
all  applicable  federal,  state  and local  laws and  regulations  relating  to
pollution control and environmental contamination including, without limitation,
all laws and

transportation,  recovery, removal, discharge or disposal of hazardous materials
(as defined below) and all laws and  regulations  with regard to record keeping,
notification  and  reporting  requirements  respecting  Hazardous  Materials (as
defined  below),  except  for such  noncompliance  as would not cause a Material
Adverse Effect.  Seller has not received written notice of any administrative or
judicial  proceeding  pursuant to such laws or regulations.  To the knowledge of
Seller,  there is no basis for the assertion of a valid  material  claim against
Seller relating to environmental  matters  including,  without  limitation,  any
claim arising from past or present environmental  practices,  asserted under the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended from time to time ("CERCLA", the Resource Conservation and Recovery Act,
as amended  form time to time  ("RCRA") or any other  federal,  state,  or local
statute, code, rule, regulation, ordinance, order, decree, or other governmental
authority  as now in  effect.  For  purposes  of this  Section  2.11,  the  term
"Hazardous  Materials" means materials  defined as "hazardous  wastes" or "solid
wastes" in CERCLA,  RCRA or in any similar  federal,  state,  or local  statute,
code,  rule,  regulation,   ordinance,  order,  decree,  or  other  governmental
authority as now in effect.

         2.12     TAX MATTERS.

                  (a) Except with respect to Taxes (as defined  below) for which
adequate  reserves are included in the Financial  Statements,  Seller has timely

through the Closing. For purposes of this Section 2.12(a),  timely payment shall
include  payment in accordance  with any available  extensions  and recording of
balances due as a Trade Payable.

         2.19     LEASES.

                  (a)  Seller  does  not  own  any  real  property.  Seller  has

any existing law of any building,  zoning,  health,  safety or other  ordinance,

and without payment of any royalties or other consideration to any party to this
Agreement  or to any  other  person.  Seller  has not  granted  any  outstanding
licenses in any of the Intangible  Property,  nor is Seller under any obligation
to grant the same.

         2.22  LIENS.  Except as set forth on  Schedule  2.22,  (a) Seller  owns

specifically set forth in Schedule 2.22 or liens or other encumbrances  securing
Taxes not yet due or payable (collectively, "Permitted Liens").

         2.23 EMPLOYEE  BENEFIT PLANS.  Set forth in Schedule 2.23, is a list of
all  pension,   profit  sharing,   retirement,   bonus,  executive  or  deferred

Division  of  Seller.   The  items  described  in  the  foregoing  sentence  are
hereinafter  sometimes referred to collectively as "Employee  Plans/Agreements."
True and correct copies of all written Employee Plans/Agreements,  including all
amendments  thereto,  have  heretofore  been  provided  to  Buyer.  Seller is in
material  compliance  with and has made all  payments  due  under  all  Employee

correct list of:

                  (a) All employees of Midwest Division to whom Seller is paying

current annual rate of compensation  for each employee and in the case of hourly
or commission employees identifies



                                                     - 14 -

certain  reasonable  ranges of rates and the number of employees  falling within
each such range; and

                  (b) All  amounts  owed to  employees  of Midwest  Division  of
Seller for accrued sick pay, vacation pay, and bonus pay.

         2.25 BANK ACCOUNTS. Schedule 2.25 sets forth the names and locations of
all banks,  trust companies,  savings and loan  associations and other financial
institutions at which Midwest Division of Seller maintains safe deposit boxes or
accounts of any nature and names of all persons authorized to draw thereon, make
withdrawals therefrom or have access thereto.

         2.26 ACCOUNTS RECEIVABLE. Each of the accounts receivable of Seller (a)
arose from bona fide sales in the ordinary  course of business,  (b) was entered
into under circumstances and by methods usual and customary in Seller's business
in the applicable  state and the collection  practices used with respect thereto
have been in all respects  legal and proper and (c) was entered into, and credit
granted pursuant  thereto,  consistent with Seller's  historical credit policies
and practices. The books of Seller correctly record the principal balance of all
accounts  receivable and each of the security  instruments  securing any account
receivable,  if any,  constitutes  a valid  lien in  favor  of  Seller  upon the
property which it describes,  and is enforceable  (subject to the qualifications
that  enforcement of the rights and remedies  created  thereby is subject to (a)
bankruptcy,  insolvency,  reorganization,  moratorium, and other laws of general
application  affecting  the rights and  remedies of  creditors,  and (b) general
principles of equity  (regardless of whether such enforcement is considered in a
proceeding in equity or at law)) by Seller and its transferees. The reserves for
doubtful  accounts  shown or reflected on the Financial  Statements are adequate
and were calculated consistent with past practice.

         2.27 INVENTORY.  The inventories of the Midwest Division of Seller have
a commercial  value (lower of cost or market  value) at least equal to the value
shown on Seller's Financial Statements.

         2.28  BROKERS AND  FINDERS.  Neither  Seller nor any of its  respective
officers, directors,  employees or shareholder has employed any broker or finder
or incurred any liability for any brokerage fees, commissions or finders fees in
connection with the transactions contemplated by this Agreement.

         2.29 DISCLOSURE.  No  representations or warranties of Seller contained
in this Agreement and no statement contained in any document (including, without
limitation,  the  Financial  Statements  and the  schedules to this  Agreement),
certificate,  or other writing  furnished or to be furnished by Seller to Buyer,
HealthCare or any of its representatives pursuant to the provisions hereof or in
connection with the transactions  contemplated hereby,  contains or will contain
any  untrue  statement  of a  material  fact or omits or will  omit to state any

                        SECURITIES LAWS AND UNDERTAKINGS

         5.1      SECURITIES LAWS.

                  (a)   INVESTMENT   REPRESENTATIONS.   Seller   represents   to
HealthCare as follows:

                           (i) The  Convertible  Note and the HealthCare  Shares
are being acquired for its own account and for  investment  only, and not with a
view  to the  distribution  of all or any  part of the  Convertible  Note or the
HealthCare Shares,  except pursuant to (i) an effective  registration  statement
covering such  Convertible Note or such shares as contemplated in Section 5.2 or
(ii) an  available  exemption  from  registration,  and the  acquisition  of the
Convertible Note and the HealthCare Shares by Seller and their continued holding
thereof as may be required by law and the terms hereof are  consistent  with its
financial position.

                           (ii)  Seller  has  had  such  access  to  information
regarding the business and finances of HealthCare, and has met and discussed the
business and finances of HealthCare with its management  employees to the extent
it deems  necessary,  and has received and read, and understands the contents of
the Prospectus.

                  (b)      LIMITATIONS ON TRANSFER.

                           (i) Except as expressly  provided in this  Agreement,
Seller shall not, directly or indirectly,  offer or sell, pledge,  transfer,  or
otherwise  dispose  of  all or  any  portion  of  the  Convertible  Note  or the
HealthCare Shares, or solicit any offer to buy,  purchase,  or otherwise acquire
or take a pledge of all or any portion of the Convertible Note or the HealthCare
Shares, as the case may be, except (A) in the manner and to the extent described
in (i) a registration  statement in effect under the Securities Act of 1933 (the
"Act") covering the Convertible Note or the HealthCare  Shares and as to which a
prospectus  meeting the  requirements  of the Act is duly delivered and filed as
necessary to qualify the shares under  applicable  state securities laws or (ii)
an  opinion of  counsel  for  Seller,  which  opinion  is in form and  substance
reasonably  satisfactory  to counsel  for  HealthCare,  to the effect  that such
proposed offer, sale, pledge,  transfer, or other disposition of the Convertible
Note or the  HealthCare  Shares may lawfully be made without such  registration,
delivery,  and  qualification or (B) pursuant to trades made on the ASE after 90
days  following the Closing  pursuant to Rule 904 of Regulation S under the Act,
provided such resale on the ASE complies with applicable  state securities laws.
Seller  acknowledges  that it has consulted with counsel  concerning the limited
availability  of exemptions from  registration  under the Act and it understands
that it (i) may bear the economic risk of investment in the Convertible Note and
the  HealthCare  Shares for an  indefinite  period of time  because  neither the
Convertible  Note nor the HealthCare  Shares have been registered  under the Act
and, therefore, cannot be sold unless they are subsequently registered under the
Act or qualified as  necessary  under  applicable  state  securities  laws or an
exemption from  registration  under the Act, such as that contained in Rule 904,
or from qualification under state securities laws, is available,  (ii) except as
provided in this Agreement,



                                                     - 20 -

HealthCare is not obligated to register the  Convertible  Note or the HealthCare
Shares under the Act or qualify them under  applicable  state  securities  laws,
(iii) that absent  registration  under the Act, neither the Convertible Note nor
the  HealthCare  Shares may ordinarily be sold in the United States for at least
two years after the Closing and then only in accordance  with Rule 144 under the
Act or in a bona fide transaction not involving a public offering to a purchaser
who shall be subject to the same  restrictions  on any resale,  (iv) that absent
qualification   under   applicable  state  securities  laws,  the  sale  of  the
Convertible  Note and the HealthCare  Shares may be restricted by such laws; and
(v) the HealthCare Shares may not be sold,  transferred or otherwise disposed of
in the province of Alberta,  Canada, or traded through the facilities of the ASE
for a period of 90 days following the Closing.

                           (ii)  Notwithstanding  any other  provisions  of this
Agreement,  Seller  shall  not,  directly  or  indirectly,  sell,  transfer,  or
otherwise  dispose  of  all or  any  portion  of  the  Convertible  Note  or the
HealthCare Shares within 12 months after the date of purchase of the Convertible
Note or the  HealthCare  Shares,  as the case may be, except in accordance  with
Regulation 204.011 of the Pennsylvania Code.

                  (c) LEGENDS ON  CERTIFICATES.  Certificates  representing  the
HealthCare Shares shall be endorsed with legends,  (i) substantially in the form
set  forth  in  Schedule  5.1(c)(i)  hereto,  and  (ii) to the  effect  that the
HealthCare Shares may not be traded in Canada for 90 days following the Closing.
HealthCare  need not  recognize  any  person  other  than  Seller as having  any
interest in or to the  HealthCare  Shares unless the  acquisition  thereof shall
have been made in compliance with Subsection 5.1(b) above.  HealthCare may issue
appropriate stop transfer  instructions to the transfer agent for the HealthCare
Shares to prevent transfers in violation of Subsection 5.1(b) hereof.

                  (d)      REMOVAL OF LEGENDS.

                           (i) At any  time  while  the  HealthCare  Shares  are
registered  under the Act and  qualified as  necessary  under  applicable  state
securities laws, HealthCare shall, upon written request,  cause the certificates
representing  the  HealthCare  Shares to be  reissued  free of all  legends  and
withdraw  all  stop  transfer  instructions.  Upon the  termination  of any such
registration,  Seller and any transferee who owns HealthCare Shares  represented
by a certificate  without such legends,  shall,  upon written request,  promptly
return such  certificate  to HealthCare  for reissue for a certificate  endorsed
with the legends  specified  in, and  otherwise  subject to, the  provisions  of
Subsection 5.1(c). Three years after the Closing,  HealthCare's right to request
the return of  unlegended  certificates  for  previously  registered  HealthCare
Shares shall  terminate and HealthCare  shall,  upon written  request of Seller,
cause any  certificates  bearing one or more legends to be reissued free of such
legends and withdraw all stop transfer  instructions,  provided that Rule 144(k)
under the Act, or a comparable rule, is in effect in  substantially  its present
form and Seller furnishes to HealthCare evidence  satisfactory to HealthCare and
its counsel that they meet the requirements of such rule.

                           (ii) HealthCare shall, upon written request,  cause a
certificate  representing  all or a  portion  of  the  HealthCare  Shares  to be
reissued free of all legends



                                                     - 21 -

and shall withdraw all stop transfer  instructions  upon the provision by Seller
of a declaration to The R-M Trust Company as transfer agent in substantially the
form set forth in Schedule 5.1(d)(ii) hereto.

         5.2      REGISTRATION UNDERTAKING.

                  (a)      DEMAND REGISTRATION.

                           (i)   REQUEST  FOR   REGISTRATION.   The  holders  of
HealthCare  Shares may  request  registration  under the Act of such  HealthCare
Shares as are described in the notice to HealthCare requesting such registration
as provided  in Section  5.2(b)(ii).  Within ten days after  receipt of any such
request,  HealthCare  will  give  written  notice of such  request  to all other
holders  of  HealthCare  Shares  and  will  include  in  such  registration  all
HealthCare  Shares  with  respect  to which  the  holder  has  given  notice  to
HealthCare of such  holder<018>s  request for inclusion  therein  within 30 days
after the receipt by such holder of HealthCare<018>s notice.

                           (ii) DEMAND  REGISTRATION.  The holders of HealthCare
Shares will collectively be entitled to two requests for demand  registration as
provided in subsection (i) above (the "Demand Registrations") and those requests
may be made at any time  specified  by the  holders  of at least  25% of all the
outstanding  HealthCare  Shares.  The Demand  Registrations  will be  short-form
registrations  on Form  S-3 or any  successor  form  thereof  if  HealthCare  is
permitted  to use such short form.  Except for (i) shares of  HealthCare  common
stock owned by Gregory J.  Frazer,  Carissa  Bennett or Jami  Tanihana for which
registration rights have been granted prior to the date of this Agreement,  (ii)
all shares of HealthCare common stock or warrants to purchase such shares issued
or  issuable  in  connection  with the offer of the  February  Special  Warrants
described in the HealthCare Capital Corp. Preliminary Prospectus dated July ___,
1996, draft dated July 12, 1996, (iii) all shares of HealthCare  common stock or
warrants to purchase such shares issued or issuable in connection with the offer
of the September  Special  Warrants  described in the Prospectus,  no securities
other than the HealthCare  Shares shall be included in the Demand  Registrations
without  the  consent  of the  holders  of at  least  50  percent  of  all  then
outstanding  HealthCare Shares that have not been previously registered pursuant
to this Article V, which consent shall not be unreasonably withheld.

                  (b) PIGGYBACK REGISTRATION.  HealthCare agrees that, if at any
time from and after the  Closing  HealthCare  proposes  to  register  any of its
securities  under the Act,  HealthCare  will (i) promptly  notify the holders of
HealthCare Shares that such Registration Statement (as hereinafter defined) will
be filed and that the HealthCare Shares which are then held by such holders will
be included in such Registration  Statement at their request and (ii) subject to
the next sentence of this subsection (b), cause such  Registration  Statement to
cover all  HealthCare  Shares  which it has been so  requested to include by the
Participating  Holders  (as  hereinafter  defined),  provided  such  request  is
delivered to HealthCare not later than 20 days after such notice is given to the
holders of HealthCare Shares and specifies the number of HealthCare Shares to be
included in the proposed registration. Notwithstanding the foregoing provisions,
if the registration  statement relates to an underwritten offering of HealthCare
Shares and the managing  underwriter shall inform in writing  HealthCare and the
Participating Holders that the



                                                     - 22 -

<PAGE>



managing underwriter believes that the number of shares requested to be included
in such registration  would  materially,  adversely affect its ability to effect
such offering,  then HealthCare will include in such  registration the number of
HealthCare  Shares which  HealthCare is so advised can be sold in (or during the
time of) such offering as follows:  first,  all shares proposed by HealthCare to
be sold for its own account, and, second, such HealthCare Shares requested to be
included  in such  registration,  pro rata by the  Participating  Holders on the
basis of the number of HealthCare Shares so proposed to be sold and so requested
to be  included;  PROVIDED,  HOWEVER,  that  HealthCare  shall be  obligated  to
register  any  HealthCare  Shares so excluded  from the  registration  statement
pursuant to a registration  statement filed 90 days after the  effectiveness  of
such initial  registration  statement  or such greater  number of days as may be
specified in "lock-up"  agreements  entered into with the managing  underwriter.
For the  purposes of this  Agreement,  "Registration  Statement"  shall mean any
registration statement of HealthCare that covers any of its securities under the
Act,  including the prospectus,  amendments and supplements to such Registration
Statement,  including post-effective  amendments,  all exhibits and all material
incorporated by reference in such Registration Statement.

                  (c) Whenever the holders of HealthCare  Shares have  requested
that any HealthCare Shares be registered pursuant to this Agreement,  HealthCare
will  use its best  efforts  to  effect  the  registration  and the sale of such
HealthCare Shares in accordance with the intended method of disposition thereof,
and pursuant thereto HealthCare will as expeditiously as possible:

                           (i)   prepare   and  file  with  the  United   States
Securities and Exchange  Commission  (the "SEC") a  Registration  Statement with
respect to such  HealthCare  Shares and use its reasonable best efforts to cause
such  Registration  Statement  to become  effective  and to remain  continuously
effective for a period which will terminate  when all HealthCare  Shares covered
by such Registration  Statement, as amended from time to time, have been sold or
a period of one year, whichever is shorter;

                           (ii)  prepare  and file with the SEC such  amendments
and post- effective amendments to the Registration  Statement and the prospectus
as may be necessary to keep the Registration  Statement effective for the period
specified in Section  5.2(c)(i) and to comply with the provisions of the Act and
the  Securities  Exchange  Act of 1934 (the  "1934  Act")  with  respect  to the
distribution of all HealthCare  Shares covered by such  Registration  Statement;
PROVIDED  that,  at a time  reasonably  prior to the  filing  of a  Registration
Statement or prospectus,  or any amendments or supplements  thereto,  HealthCare
will furnish to the Participating Holders copies of all documents proposed to be
filed, in order to allow the Participating  Holders and their counsel to comment
on such documents;

                           (iii) notify the Participating Holders promptly,  and
confirm such advice in writing,  (a) when the  prospectus  or any  supplement or
post-effective  amendment has been filed,  and with respect to the  Registration
Statement or any post-effective  amendment,  when the same has become effective,
(b) of any request by the SEC for amendments or supplements to the  Registration
Statement or the prospectus or



                                                     - 23 -

for  additional  information,  (c) of the  issuance by the SEC of any stop order
suspending the effectiveness of the Registration  Statement or the initiation of
any  proceedings  for that purpose,  and (d) of the receipt by HealthCare of any
notification  with  respect  to the  suspension  of the  qualification  of  such
HealthCare  Shares for which  registration  has been  requested  for sale in any
jurisdiction  or the  initiation  or  threatening  of any  proceeding  for  such
purpose;

                           (iv) make reasonable  effort to obtain the withdrawal
of any order suspending the effectiveness of the Registration Statement;

                           (v)  furnish  to the  Participating  Holders at least
five  copies of the  Registration  Statement  and any  post-effective  amendment
thereto,   including   financial   statements  and   schedules,   all  documents
incorporated therein by reference and all exhibits (including those incorporated
by reference);

                           (vi)  deliver  to each  Participating  Holder as many
copies  of the  prospectus  (including  each  preliminary  prospectus)  and  any
amendment or supplement  thereto as such holder may reasonably  request in order
to  facilitate  the  disposition  of  the  HealthCare  Shares  covered  by  such
Registration Statement;

                           (vii)  prior to any  public  offering  of  HealthCare
Shares, use its reasonable best efforts to register or qualify or cooperate with
the  Participating  Holders and the  underwriters,  if any, and their respective
counsel in connection with the  registration or qualification of such HealthCare
Shares  for  offer  and  sale  under  the  securities  or blue  sky laws of such
jurisdictions  as  the  Participating  Holders  or  any  underwriter  reasonably
requests in writing and do any and all other reasonable acts or things necessary
or advisable to enable the distribution in such  jurisdictions of the HealthCare
Shares covered by such Registration Statement; PROVIDED that HealthCare will not
be required to qualify generally to do business in any jurisdiction  where it is
not then so qualified  or to take any action  which would  subject it to general
service of process in any such jurisdiction where it is not then so subject;

                           (viii) [Not used];

                           (ix)  in  the  event  of  any   underwritten   public
offering,   enter  into  and  perform  its  obligations  under  an  underwriting
agreement,  usual and customary in form,  with the managing  underwriter of such
offering;  the  Participating  Holders  shall also enter into and perform  their
obligations under such agreement,  usual and customary in form; HealthCare shall
take such  other  actions  as the  underwriters  reasonably  request in order to
expedite or facilitate a disposition  of the  HealthCare  Shares covered by such
Registration Statement;

                           (x)  upon  request,  furnish  to  each  Participating
Holder a signed  counterpart,  addressed  to such  holder,  of (a) an opinion of
counsel for HealthCare,  dated the effective date of such registration statement
(or, if such registration includes an



                                                     - 24 -

<PAGE>



underwritten  public  offering,   dated  the  date  of  the  closing  under  the
underwriting agreement), and (b) a "comfort" letter, dated the effective date of
such registration  statement (and, if such registration includes an underwritten
public  offering,   dated  the  date  of  the  closing  under  the  underwriting
agreement),  signed by the  independent  public  accountants  who have certified
HealthCare's  financial  statements  included  in such  registration  statement,
covering  substantially  the same  matters  with  respect  to such  registration
statement  (and  the  prospectus  included  therein)  and,  in the  case of such
accountants'  letter,  with  respect  to events  subsequent  to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants'  letters  delivered to  underwriters in underwritten  public
offerings of securities and, in the case of the accountants'  letter, such other
financial   matters,   as  the  principal   underwriter  with  respect  to  such
registration may reasonably  request (or, if such  registration does not involve
an underwritten  offering, as may reasonably (i.e., in conformity with Statement
on Auditing Standards No. 72, as amended, or any successor statement thereto) be
requested  by holders of a majority of the  HealthCare  Shares  included in such
registration);

                           (xi) immediately notify each Participating  Holder at
any time when a prospectus  relating  thereto is required to be delivered  under
the Act, upon discovery  that, or upon the happening of any event as a result of
which,  the  prospectus  included  in such  Registration  Statement,  as then in
effect,  includes an untrue  statement of a material  fact or omits to state any
material fact required to be stated  therein or necessary to make the statements
therein not misleading in the light of the circumstances  then existing,  and at
the request of any such  holder,  promptly  prepare and furnish to such holder a
reasonable  number  of  copies  of a  supplement  to or  an  amendment  of  such
prospectus  as  may  be  necessary  so  that,  as  thereafter  delivered  to the
purchasers  of such  HealthCare  Shares,  such  prospectus  shall not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements  therein not misleading in
the light of the circumstances then existing;

                           (xii) Otherwise use its reasonable  efforts to comply
with all applicable  rules and regulations of the SEC under the Act and the 1934
Act, take such other actions as may be  reasonably  necessary to facilitate  the
registration or the  disposition of the HealthCare  Shares  hereunder;  and make
available to its security holders,  as soon as reasonably  practicable,  but not
later than the  Availability  Date (as defined  below),  an  earnings  statement
covering a period of at least twelve months,  beginning after the effective date
of the applicable Registration Statement, which earnings statement shall satisfy
the  provisions  of  subsection  11(a)  of the  Act.  For  the  purpose  of this
subsection 5.2(c)(xii), "Availability Date" means the 45th day following the end
of  the  fourth  fiscal  quarter  that  includes  the  effective  date  of  such
Registration  Statement,  except that, if such fourth fiscal quarter is the last
quarter of the HealthCare's fiscal year,  "Availability Date" means the 90th day
after the end of such fourth fiscal quarter).

                           (xiii) For purposes of this Article V  "Participating
Holder"  shall mean any holder of the  HealthCare  Shares whose shares are being
registered pursuant to this Article V.

                  (d) HealthCare  shall pay all expenses  incurred in connection
with any registration or other action pursuant to the provisions of this Section
5.2, other than underwriting discounts and applicable transfer taxes relating to
the HealthCare Shares sold by Seller and attorney fees and expenses of Seller in
excess of $10,000.

                  (e)  HealthCare  agrees to indemnify and hold harmless  Seller
from and against any and all losses,  claims,  damages,  liabilities or actions,
joint or several, to which Seller may become subject under the Act for any legal
or other expenses  (including  the cost of any  investigation  and  preparation)
incurred by them in connection  with any  litigation  or threatened  litigation,
whether or not  resulting  in any  liability,  but only  insofar as such losses,
claims, damages, liabilities or actions arise out of, or are based upon, (i) any
untrue statement or alleged untrue statement of a material fact contained in any
registration statement pursuant to which HealthCare Shares were registered under
the  Act  (hereinafter  called  a  "Registration  Statement"),  any  preliminary
prospectus,  the final prospectus or any amendment or supplement  thereto (or in
any application or document filed in connection therewith) or any document filed
by HealthCare in any jurisdiction in order to register or qualify the HealthCare
Shares under the securities laws thereof or the omission or alleged  omission to
state therein a material fact required to be stated therein or necessary to make
the statements  therein, in the light of the circumstances under which they were
made, not misleading, or (ii) the employment by HealthCare of any device, scheme
or artifice to defraud,  or the engaging by HealthCare  in any act,  practice or
course of business which operates or would operate as a fraud or deceit,  or any
conspiracy with respect  thereto,  in which  HealthCare  shall  participate,  in
connection with the issuance and sale of any of the HealthCare Shares; PROVIDED,
HOWEVER that (i) the indemnity  agreement contained in this Subsection (e) shall
not extend to Seller in respect of any such losses, claims, damages, liabilities
or actions  arising out of, or based upon any such untrue  statement  or alleged
untrue statement, or any such omission or alleged omission, if such statement or
omission was based upon and made in  conformity  with  information  furnished in
writing to HealthCare  by Seller  specifically  for use in  connection  with the
preparation  of  such  Registration   Statement,   any  final  prospectus,   any
preliminary  prospectus or any such  amendment or supplement  thereto (or in any
application or document filed in connection  therewith) or document filed in any
jurisdiction  in order to register or qualify the  HealthCare  Shares  under the
securities laws thereof.  HealthCare  agrees to pay any legal and other expenses
for which it is liable under this Subsection (e) from time to time (but not more
frequently than monthly) within 30 days after its receipt of a bill therefor.

                  (f) Seller will  indemnify and hold harmless  HealthCare,  its
directors,  its officers who shall have signed the  Registration  Statement  and
each person, if any, who controls HealthCare within the meaning of Section 15 of
the Act to the same extent as the foregoing  indemnity from  HealthCare,  but in
each case to the extent, and only to



                                                     - 26 -

<PAGE>



the extent, that any statement in or omission from or alleged omission from such
Registration Statement, any final prospectus,  any preliminary prospectus or any
amendment or  supplement  thereto (or in any  application  or document  filed in
connection therewith) or document filed in any jurisdiction in order to register
or qualify the HealthCare  Shares under the securities  laws thereof was made in
reliance  upon  information  furnished in writing to  HealthCare  by such Seller
specifically  for use in connection  with the  preparation  of the  Registration
Statement,  any  final  prospectus  or the  preliminary  prospectus  or any such
amendment or  supplement  thereto (or in any  application  or document  filed in
connection therewith) or document filed in any jurisdiction in order to register
or qualify the HealthCare  Shares under the securities  laws thereof;  PROVIDED,
HOWEVER,  that the  obligation  of  Seller  to  indemnify  HealthCare  under the
provisions of this  Subsection (f) shall be limited to the product of the number
of  HealthCare  Shares being sold by Seller and the market  price of  HealthCare
Shares on the date of the sale to the public of such HealthCare  Shares.  Seller
agrees to pay any legal and other  expenses  for which it is liable  under  this
Subsection (f) from time to time (but not more  frequently  than monthly) within
30 days after receipt of a bill therefor.

                  (g) If any  action is  brought  against a person  entitled  to
indemnification   pursuant  to  the  foregoing   Subsections  (e)  and  (f)  (an
"indemnified  party")  in  respect of which  indemnity  may be sought  against a
person  granting  indemnification  (an  "indemnifying  party")  pursuant to such
Subsections  (e) and (f),  such  indemnified  party shall  promptly  notify such
indemnifying party in writing of the commencement  thereof;  but the omission so
to notify  the  indemnifying  party of any such  action  shall not  release  the
indemnifying  party from any  liability  it may have to such  indemnified  party
otherwise  than on account of the indemnity  agreement  contained in Subsections
(e) and (f) of this Section  5.2. In case any such action is brought  against an
indemnified  party and it notifies  an  indemnifying  party of the  commencement
thereof,  the  indemnifying  party  against  which a claim is to be made will be
entitled to  participate  therein at its own expense  and, to the extent that it
may  wish,  to assume at its own  expense  the  defense  thereof,  with  counsel
reasonably  satisfactory to such indemnified party; PROVIDED,  HOWEVER, that (i)
if the defendants in any such action include both the indemnified  party and the
indemnifying  party and the indemnifying  party shall have reasonably  concluded
based upon advice of counsel  that there may be legal  defenses  available to it
and/or other indemnified parties which are different from or additional to those
available to the indemnified  party, the indemnified  party shall have the right
to select  separate  counsel to assume  such legal  defenses  and  otherwise  to
participate in the defense of such action on behalf of such indemnified party or
parties and (ii) in any event,  the indemnified  party shall be entitled to have
counsel chosen by such indemnified  party  participate in, but not conduct,  the
defense at the expense of the  indemnifying  party.  Upon receipt of notice from
the indemnifying  party to such  indemnified  party of its election so to assume
the defense of such action and approval by the indemnified party of counsel, the
indemnifying  party  will not be liable to such  indemnified  party  under  this
Section  5.2 for any  legal  or other  expenses  subsequently  incurred  by such
indemnified  party  in  connection  with  the  defense  thereof  unless  (i) the
indemnified  party  shall have  employed  such  counsel in  connection  with the
assumption of legal defenses in accordance with



                                                     - 27 -

proviso (i) to the next preceding sentence (it being understood,  however,  that
the  indemnifying  party  shall not be liable for the  expenses of more than one
separate  counsel),  (ii) the indemnifying party shall not have employed counsel
reasonably  satisfactory to the  indemnified  party to represent the indemnified
party within a reasonable  time after  notice of  commencement  of the action or
(iii) the  indemnifying  party has  authorized the employment of counsel for the
indemnified  party at the expense of the  indemnifying  party.  An  indemnifying
party  shall not be  liable  for any  settlement  of any  action  or  proceeding
effected without its written consent.

                  (h) In order to provide for just and equitable contribution in
circumstances in which the indemnity  agreement  provided for in Subsections (e)
and (f) of this Section 5.2 is unavailable to an indemnified party in accordance
with its terms,  HealthCare and Seller shall contribute to the aggregate losses,
claims,  damages and liabilities,  of the nature  contemplated by said indemnity
agreement,  incurred  by  HealthCare  and  Seller,  in such  proportions  as are
appropriate to reflect the relative  benefits  received by HealthCare and Seller
from any offering of the  HealthCare  Shares;  PROVIDED,  HOWEVER,  that if such
allocation is not permitted by applicable law or if the indemnified party failed
to give the notice  required under  Subsection (g) of this Section 5.2, then the
relative  fault of HealthCare  and Seller in connection  with the  statements or
omissions  which resulted in such losses,  claims,  damages and  liabilities and
other relevant equitable  considerations  will be considered  together with such
relative benefits.

                  (i) The respective  indemnity and  contribution  agreements by
HealthCare and Seller in Subsections  (e), (f), (g), and (h) of this Section 5.2
shall  remain  operative  and in full  force and  effect  regardless  of (i) any
investigation  made by  Seller or by  HealthCare  or any  controlling  person of
HealthCare or any director or any officer of HealthCare, (ii) payment for any of
the  HealthCare  Shares or (iii) any  termination of this  Agreement,  and shall
survive the delivery of the HealthCare  Shares, and any successor of HealthCare,
or of  Seller,  or of any person who  controls  HealthCare,  as the case may be,
shall be entitled to the benefit of such respective  indemnity and  contribution
agreements.  The respective indemnity and contribution  agreements by HealthCare
and Seller  contained in Subsections  (e), (f), (g), and (h) of this Section 5.2
shall be in addition to any liability which  HealthCare and Seller may otherwise
have.

                  5.3  SELL  ALONG  RIGHT.  Except  pursuant  to a  registration
statement filed pursuant to Sections 5.2(a) or 5.2(b) hereof,  whenever  Brandon
M. Dawson (the "Selling Stockholder") shall receive a bona fide offer to acquire
all or  substantially  all of the shares of HealthCare  Common Stock held by the
Selling  Stockholder from a prospective  acquiror which the Selling  Stockholder
wishes to accept,  the  Selling  Stockholder  shall give a written  notice  (the
"Notice") to each holder of HealthCare Shares (collectively,  the "Offerees") to
such effect, specifying the number of shares of Common Stock of HealthCare which
the Selling Stockholder desires to transfer. Upon receipt of the Notice, each of
the Offerees shall have the right, at such Offeree<018>s  option, to require the
Selling  Stockholder  to arrange for the sale to the  prospective  acquiror  (on
terms and



                                                     - 28 -

conditions at least as favorable to such Offeree as the terms and conditions set
out in the offer  received  by the  Selling  Stockholder)  of the number of such
Offeree<018>s holdings of shares of Common Stock which bears the same proportion
to the number of shares of Common  Stock owned by such  Offeree as the number of
shares of Common Stock being sold by the Selling  Stockholder bears to the total
number of  shares  of Common  Stock  owned by the  Selling  Stockholder.  If the
prospective  acquiror  will not acquire all the shares of Common Stock which the
Selling Stockholder and the Offerees wish to dispose of pursuant to this Section
5.3, the number of shares of Common Stock which the Selling Stockholder and each
of the  Offerees  exercising  its right and option  pursuant to this Section 5.3
shall be permitted to transfer to such prospective acquiror shall be a number of
shares equal to the number of shares which the prospective  acquiror  desires to
acquire multiplied by a fraction,  the numerator of which shall be the number of
shares of Common Stock owned by the Selling Stockholder or each such Offeree, as
applicable, and the denominator of which shall be the aggregate number of shares
of Common  Stock  owned by the Selling  Stockholder  and all such  Offerees.  An
Offeree may exercise such  person<018>s  right under this Section 5.3 by written
notice  given  within ten days after the date on which such person  received the
Notice.

         9.1      INDEMNIFICATION.

                  (a) Seller  agrees to indemnify  and hold  harmless  Buyer and
HealthCare (and its directors, officers,  shareholders,  employees,  affiliates,
agents and assigns) from and against any and all losses,  liabilities,  damages,
deficiencies,  assessments,  judgments,  costs or expenses  (including,  without
limitation,   interest,   penalties   and   reasonable   attorneys'   fees   and
disbursements) (collectively,  "Claims") arising out of or based upon the breach
or inaccuracy of any  representation  or warranty  contained herein or in any of
the documents  delivered pursuant hereto made by Seller, the  non-performance or
breach  by Seller of any  covenant,  term or  provision  to be  performed  by it
hereunder or in any of the documents  delivered pursuant hereto, or any Excluded
Liability  which may be imposed  or sought to be  imposed  on Buyer  (including,
without  limitation,  as a  result  of  noncompliance  by  any  party  with  any
applicable  bulk sales law or any comparable  statute  relating to notice to and
rights of creditors of Seller in connection with the  transactions  contemplated
hereunder).

                  (b) Buyer and HealthCare  agree to indemnify and hold harmless
Seller (and its directors, officers, shareholders, employees, affiliates, agents
and assigns) from and against any Claims arising out of or based upon the breach
or inaccuracy of any  representation  or warranty  contained herein or in any of
the  documents  delivered  pursuant  hereto  made by  Buyer or  HealthCare,  the
non-performance  or  breach  by Buyer or  HealthCare  of any  covenant,  term or
provision to be performed by it hereunder or in any of the  documents  delivered
pursuant hereto,  or any Assumed  Liability which may be imposed or sought to be
imposed  on  Seller.  The  indemnification  obligation  of Buyer and  HealthCare
hereunder is with respect to the full amount of the Claims.

                  (c) Buyer and HealthCare shall be entitled to  indemnification
from Seller under the provisions of this Section 9.1 only to the extent that (i)
Buyer and HealthCare have made a claim for indemnification within 180 days after
Closing and (ii) the Claims  subject to  indemnification  (other than Claims for
indemnification  based on any Excluded  Liabilities) exceed ten thousand dollars
($10,000) in the aggregate.  Notwithstanding  the foregoing,  Seller's liability
for all Claims subject to  indemnification  under the provisions of this Section
9.1 shall be limited



                                                     - 34 -

<PAGE>



to one hundred thousand dollars ($100,000) in the aggregate. The foregoing shall
have no effect on the indemnification obligations of Seller set forth in Section
5.2(f).

                  (d)  Buyer's and  HealthCare's  right to,  indemnification  as
provided in this Section 9.1 shall not be eliminated, reduced or modified in any
way as a result of the fact that (i) Buyer or HealthCare  had notice of a breach
or inaccuracy of any representation, warranty or covenant contained herein, (ii)
Buyer or  HealthCare  had been  provided  with access,  as requested by Buyer or
HealthCare,  to officers  and  employees  of Seller and such of Seller's  books,
documents,  contracts and records as has been provided to Buyer or HealthCare in
response to Buyer's or HealthCare's requests.

                  (e)  Buyer's  and  HealthCare's  sole  remedy to  Claims  made
pursuant to this  Section 9.1 shall be offset,  by notice to Seller,  any amount
due from Seller  pursuant to the  indemnification  provisions of this  Agreement
against (i) any payment due to Seller  under the  Convertible  Note and (ii) the
HealthCare Shares, valued for the purposes of this section as the greater of the
five (5) day average  trading price or one and 30/100 dollars ($1.30) per share.
If Seller disputes the validity of the offset,  the amount proposed to be offset
shall be deposited by Seller in a segregated bank account under joint control of
Buyer and Seller and the matter shall be resolved by  arbitration  under Section
10.12. Any undisputed portion shall be paid to the obligee.  The disputed amount
proposed to be offset shall be transferred  to the control of the  arbitrator(s)
promptly following their appointment.

         9.2      CONDITIONS OF INDEMNIFICATION.

                  (a)  A  party  entitled  to  indemnification   hereunder  (the
"Indemnified  Party")  shall  notify  the  party  or  parties  liable  for  such
indemnification  (the  "Indemnifying  Party") in writing of any Claim  which the
Indemnified  Party has  determined  has  given or could  give rise to a right of
indemnification  under  this  Agreement.  Such  notice  shall be given  within a
reasonable  (taking into  account the nature of the Claim)  period of time after
the Indemnified Party has actual knowledge thereof. The Indemnifying Party shall
satisfy its obligations under this Article IX within ten (10) days after receipt
of  subsequent  written  notice  from  the  Indemnified  Party if an  amount  is
specified therein, or promptly following receipt of subsequent written notice or
notices  specifying  the amount of such Claim or  additions  thereto;  provided,
however, that for so long as the Indemnifying Party is in good faith defending a
Claim  pursuant to Section  9.2(b)  hereof,  its  obligation  to  indemnify  the
Indemnified  Party with  respect  thereto  shall be  suspended  (other than with
respect to any costs,  expenses or other liabilities incurred by the Indemnified
Party prior to the assumption of the defense by the Indemnifying Party). Failure
to provide a notice of Claim within the time period  referred to above shall not
constitute  a defense  to a Claim or  release  the  Indemnifying  Party from any
obligation  hereunder  to the extent that such failure  does not  prejudice  the
position of the Indemnifying Party.

                  (b) If the  facts  giving  rise  to any  such  indemnification
involve any actual,  threatened or possible  Claim or demand by any person not a
party to this Agreement  against the Indemnified  Party, the Indemnifying  Party
shall be  entitled  to contest or defend such Claim or demand at its expense and
through counsel of its own choosing, which counsel shall be



                                                     - 35 -

reasonably  acceptable to the Indemnified Party, if the Indemnifying Party gives
written  notice of its intention to assume the contest and defense of such Claim
or demand to the Indemnified Party as soon as practicable,  but in no event more
than ten (10) days  after  receipt  of the  notice of Claim,  and  provides  the
Indemnified  Party with  appropriate  assurances as to the  creditworthiness  of
Indemnifying Party, that the Indemnifying Party will be in a position to pay all
fees,  expenses and judgments that might arise out of such Claim or demand.  The
Indemnified  Party shall have the  obligation to cooperate in the defense of any
such Claim or demand and the right,  at its own expense,  to  participate in the
defense of any Claim.  So long as the  Indemnifying  Party is  defending in good
faith any such Claim or demand asserted by a third party against the Indemnified
Party,  the  Indemnified  Party  shall not  settle or  compromise  such Claim or
demand.  The Indemnifying Party shall have the right to settle or compromise any
such Claim or demand  without the consent of the  Indemnified  Party at any time
utilizing  its own  funds to do so if in  connection  with  such  settlement  or
compromise  the  Indemnified  Party is fully  released by the third party and is
paid in full any  indemnification  amounts due hereunder.  The Indemnified Party
shall make  available  to the  Indemnifying  Party or its agents all records and
other materials in the Indemnified Party's possession  reasonably required by it
for its use in  contesting  any third party Claim or demand and shall  otherwise
cooperate,  at the expense of the Indemnifying  Party, in the defense thereof in
such manner as the Indemnifying Party may reasonably request. Whether or not the
Indemnifying  Party elects to defend such Claim or demand, the Indemnified Party
shall have no obligation to do so.

                  (c) The Indemnifying  Party shall pay to the Indemnified Party
all reasonable costs and expenses  (including,  but not limited to, the fees and
disbursements  of any Indemnified  Party's outside legal counsel and the charges
of any  Indemnified  Party's  in-house legal counsel)  incurred by such party in
connection with this indemnity or the enforcement hereof.

                  (d) This  indemnity  shall be  binding  upon the  Indemnifying
Party, its heirs,  representatives,  administrators,  executors,  successors and
assigns  and shall  inure to the  benefit  of and shall be  enforceable  by each
Indemnified  Party, its successors,  endorsees and assigns  (including,  but not
limited to, any entity to which Buyer assigns or sells all or any portion of its
interest).  If this indemnity is executed by more than one person or entity, the
liability of the undersigned hereunder shall be joint and several.

                  (e) No failure or delay on the part of any  Indemnified  Party
to exercise any power,  right or privilege under this indemnity shall impair any
such power,  right or privilege or be construed to be a waiver of any default or
any  acquiescence  therein,  nor shall any single or partial  exercise of power,
right or privilege  preclude other or further  exercise  thereof or of any other
right,  power or  privilege.  No  provision  of this  indemnity  may be changed,
waived,  discharged or terminated  except by an instrument in writing  signed by
the  party  against  whom  enforcement  of  the  change,  waiver,  discharge  or
termination is sought.

         9.3 SURVIVAL OF  REPRESENTATIONS.  All  representations  and warranties
made by the  parties in this  Agreement  set forth in Article II and Article III
hereof shall survive the consummation of the  transactions  contemplated by this
Agreement  for a period  ending  180 days  after  the  Closing  (except  for the

         10.12    RESOLUTION OF DISPUTES.

                  (a) ARBITRATION. Any dispute, controversy or claim arising out
of or relating to this Agreement or the  performance by the parties of its terms
shall be settled by binding arbitration held in Philadelphia,  Pennsylvania,  in
accordance  with the Commercial  Arbitration  Rules of the American  Arbitration
Association then in effect,  except as specifically  otherwise  provided in this
Section 10.12.  Notwithstanding  the foregoing,  Buyer, in its  discretion,  may
apply  to a court  of  competent  jurisdiction  for  equitable  relief  from any
violation  or  threatened  violation  of the  provisions  of  Seller  under  any
noncompetition  and   confidentiality   agreements  executed  pursuant  to  this
Agreement.

                  (b) ARBITRATORS. Following thirty (30) days' written notice by
any party of intention to invoke  arbitration,  any dispute  arising  under this
Agreement or other schedules hereto and not mutually resolved within such thirty
(30) day period shall be determined by a single arbitrator upon whom the parties
agree or, if the parties  cannot  agree on a single  arbitrator  within five (5)
business days  following  such thirty (30) day period,  then by a board of three
(3) arbitrators, which arbitrator(s) shall be selected for each such controversy
so arising hereunder.  If three (3) arbitrators are necessary,  each party shall
have the right to pick one  arbitrator  and the two  arbitrators so chosen shall
have the  right  to  select a third  arbitrator.  Any  party  who is  unable  or
unwilling to so select an arbitrator in a timely manner, shall forfeit its right
to participate in the selection process.  If a selected  arbitrator is unable or
unwilling to act, or if for any other  reason an  appointment  of the  requisite
number or  arbitrators  cannot  be made,  then any  party,  on behalf of all the
parties,  may request appointment of arbitrator(s) by the presiding judge of the
federal courts located in the Eastern District of Pennsylvania.

                  (c) PROCEDURES;  NO APPEAL. The arbitrator(s) shall allow such
discovery as the arbitrator(s) determine appropriate under the circumstances and
shall resolve the dispute as  expeditiously  as  practicable,  and if reasonably
practicable,  within  120 days after the  selection  of the  arbitrator(s).  The
arbitrator(s)  shall give the parties  written notice of the decision,  with the
reasons  therefor  set out,  and  shall  have  thirty  (30) days  thereafter  to
reconsider  and modify such  decision  if any party so requests  within ten (10)
days after the decision.  Thereafter, the decision of the arbitrator(s) shall be
final,  binding,  and  nonappealable  with  respect  to all  persons,  including
(without  limitation)  persons who have failed or refused to  participate in the
arbitration process.

                  (d) AUTHORITY. The arbitrator(s) shall have authority to award
relief under legal or equitable  principles,  including  interim or  preliminary
relief,  and to allocate  responsibility for the costs of the arbitration and to
award  recovery of attorney fees and expenses in such manner as is determined to
be appropriate by the arbitrator(s).

                  (e) ENTRY OF JUDGMENT. Judgment upon the award rendered by the
arbitrator(s)  may be entered in any court having in personam and subject matter
jurisdiction.  Seller,  Buyer and  HealthCare  hereby  submit to the in personam
jurisdiction  of the  federal  and  state  courts  in the  Eastern  District  of
Pennsylvania for the purpose of confirming any such award and entering  judgment
thereon.

and all evidence  given or discovered  pursuant  hereto,  shall be maintained in
confidence by all parties.

                  (g)   CONTINUED   PERFORMANCE.   The  fact  that  the  dispute
resolution  procedures specified in this Section 10.12 shall have been or may be
invoked shall not excuse any party from  performing its  obligations  under this
Agreement,  and during the  pendency of any such  procedure  all  parties  shall
continue to perform their respective  obligations in good faith,  subject to any
rights to terminate this Agreement that may be available to any party.

direct the application of the laws of another jurisdiction.

         10.14  COUNTERPARTS.  This  Agreement  may be  executed  by the parties
hereto in separate  counterparts,  each of which when so executed and  delivered
shall be an original,  but all such counterparts  shall together  constitute one
and the same  instrument.  Each  counterpart  may  consist of a number of copies
hereof each signed by less than all, but together  signed by all, of the parties
hereto.

         10.15 ENTIRE AGREEMENT. This Agreement (including the schedules hereto)
and the agreements,  certificates and other documents  delivered pursuant hereto
contain  the  entire   agreement   between  the  parties  hereto.   All  parties
collaborated  in the  preparation  of this Agreement and it has been reviewed by
attorneys for each party.  No one party should be  considered  the author of any
specific language for purposes of legal presumptions.

         10.16 FURTHER ASSURANCES. Both before and after the Closing, each party
will  cooperate  in good faith  with the  others  and will take all  appropriate
action and execute any documents,  instruments,  or conveyances of any kind that
may be  reasonable  necessary or desirable to carry out any of the  transactions
contemplated hereunder.

         10.17 BOOKS AND  RECORDS.  For a period of five years after the Closing
(a) Seller shall provide  reasonable  access during normal business hours to the
books and records of the Midwest  Division in  existence  on the date of Closing
that do not constitute a part of the  Transferred  Assets and (b) HealthCare and
Buyer shall provide  reasonable access during normal business hours to the books
and records  relating to the Midwest  Division in  existence  on the date of the
Closing that constitute a part of the Transferred Assets.

         10.18 RELEASE OF SELLER.  All parties to this Agreement shall use their
best  efforts to obtain the  consent to  assignment  and  release of Seller from
liability  with respect to the Business  Premises  and the  contracts  listed in
Schedule  2.5, it being  understood  and agreed that no party to this  Agreement
shall be required to obtain the consent to assignment and release of Seller from
liability with respect to the Contracts listed in Schedule 2.18(a).

dissolves or otherwise ceases the business use of (which shall not be later than
180 days  after  such  dissolution)  the names  "Hearing  Health  Services"  and
"Audio-Vestibular  Testing  Center," Hearing Health shall cause such names to be
transferred and conveyed to Buyer without further consideration.

         10.20 PASS  THROUGH OF RIGHTS  AND  OBLIGATIONS.  In the event that the
parties  hereto are unable to obtain any of the necessary  consents set forth in
Schedule 2.5 hereto prior to the Closing,  each of the parties  hereto agrees to
use its  reasonable  best  efforts  subsequent  to the  Closing  to obtain  such
consents. Seller agrees that until such time as such consents are obtained or in
the event the parties  hereto are unable to obtain such  consents,  Seller shall
pass through to Buyer or HealthCare (or their respective designees) the benefits
and the  obligations  arising under the agreements  listed in Schedule 2.5 as if
such  agreements  were  assigned  to Buyer or  HealthCare  (or their  respective
designees)  pursuant  to this  Agreement.  Buyer  and  HealthCare,  jointly  and
severally, agree to perform fully the obligations under such agreements. Each of
Buyer and HealthCare  hereby release and discharge Seller from all Claims (known
or unknown)  arising out of or relating to the failure of the parties  hereto to
obtain any of the  necessary  consents set forth in Schedule 2.5 hereto prior to
the Closing.

         10.21 LEASE RENEWALS. Each of Buyer and HealthCare covenants and agrees
not to renew or extend  any lease  currently  in effect  covering  the  Business
Premises  unless  Hearing  Health or AVTC, as the case may be, has been released
from all obligations arising under such lease.

         10.22 JOINT AND SEVERAL  OBLIGATIONS  OF SELLER.  All  representations,
warranties,  covenants,  and  obligations of Seller under this Agreement are the

hereof and to the following provisions:

                  (a)  210,000   HealthCare   Shares  shall  be  subject  to  no

                  (b) 118,000 HealthCare Shares may not be sold, transferred, or
         otherwise  disposed of in any manner  whatsoever  until such shares are
         released from such restrictions in the increments and on the dates (the
         "Release Dates") set forth below:

                       Release                       Number of
                        DATES                     SHARES RELEASED

              November 30, 1997                      39,333
              November 30, 1998                      39,333
              November 30, 1999                      39,334
                                                     ------
              Total                               118,000

         The HealthCare  Shares subject to the  restrictions  of this Subsection
         1.5(b)  shall be issued  in three  certificates-one  for the  number of
         shares shown opposite each of the Release Dates which will be delivered
         to the Shareholder at Closing.  Each such  certificate will be endorsed
         with a counterpart of the following legend:

                  "The shares  represented  by this  certificate  are subject to
                  restrictions  which do not permit  their  sale,  transfer,  or
                  other disposition prior to [insert appropriate Release Date]."

         In  addition,   HealthCare   shall  issue   appropriate  stop  transfer

provided in Subsections (a), (b), and (c) below.




                                                     - 3 -

                  (a) EARN-OUT.  The income of the business  being acquired from
         Company hereunder (the "Business")  shall be separately  determined for
         each of the three  12-month  periods  ending on the Release  Dates (the
         "Earned-Out Years"). Such income shall be determined in accordance with
         generally accepted accounting  principles applied on a basis consistent
         with HC Subsidiary's accounting practices. If for any Earn-Out Year the
         income  of  the  Business  before  interest,  taxes,  depreciation  and
         amortization  but after corporate  overhead  allocation  falls below an
         amount  equal to 20% of the net revenues of the Business for such year,
         then for each  $1.72  of the  shortfall  one  Retained  Share  shall be
         canceled or alternately Shareholder shall pay HealthCare one dollar for
         each one dollar of the shortfall.  The corporate overhead allocation to
         be charged  against the  Business  shall equal 6% of its net  revenues.
         Within 60 days  following  the end of each  Earn-Out  Year,  HealthCare
         shall deliver to the Shareholder a certificate for a number of Retained
         Shares equal to (i) 26,666 shares after year one and (ii) 26,667 shares
         after  years two and three less the number of shares (if any)  canceled
         as a result of the foregoing provision.  Notwithstanding the foregoing,
         the certificate  issued to the  Shareholder  after the end of the first
         Earn-Out  Year shall  also be reduced by the number of shares,  if any,
         canceled pursuant to the terms of Subsections 1.6(b) and (c) below. For
         purposes  of this  Section  1.6(a),  "net  revenues"  shall  mean gross
         revenues less returns and allowances. The HealthCare Shares represented
         by the  certificates  delivered  to the  Shareholder  pursuant  to this
         subsection shall remain subject to the provisions of Article VI hereof.

                  (b)  ACCOUNTS  RECEIVABLE.  On the  200th  day  following  the
         Closing,  one  Retained  Share shall be canceled  for each $1.72 of net
         accounts  receivable  as set  forth  on the  Statement  of Net  Working
         Capital  (as  defined  in  Section  1.7  below)   which  then   remains
         uncollected,  provided,  however,  that the  Shareholder  may  elect to
         reimburse  HealthCare  one dollar for each  dollar of such  uncollected
         accounts  receivable in lieu of such  cancellation of Retained  Shares.
         After  such   cancellation   of  Retained  Shares  or  the  payment  by
         Shareholder for such uncollected  accounts receivable has been received
         by HealthCare, the uncollected accounts receivable shall be assigned to
         Shareholder.   During  the  first  200  days   following  the  Closing,
         Shareholder  and  HC  Subsidiary  shall  mutually  participate  in  the
         collection process of such accounts receivable.

                  (c)  LONG-TERM  DEBT.  To the extent  that the Company has any
         long-term  debt or any other  noncurrent  liabilities as of the Closing
         date, Retained Shares shall be canceled in an aggregate amount equal to
         one share for each $1.72 of long term debt or noncurrent  liability or,
         alternatively, the Shareholder shall pay HealthCare one dollar for each
         dollar of long-term debt or noncurrent liability.

         1.7      NET WORKING CAPITAL ADJUSTMENT.

                  (a) For  purposes of this  Agreement,  "Net  Working  Capital"
         shall equal (i) cash, money market accounts,  accounts  receivable (net
         of reasonable  provisions for doubtful  accounts),  inventory,  prepaid
         expenses  (including  for magazine  advertising)  and all other current
         assets of the Company as of Closing  less (ii) all current  liabilities
         of the



                                                     - 4 -

<PAGE>



         Company as of Closing  including  but not  limited to  liabilities  for
         inventory,  office supplies,  ordinary compensation payables,  employee
         benefits and taxes (excluding  accrued sick and vacation pay),  bonuses
         (including all related payroll taxes and employee  benefits),  personal
         and real  property  taxes,  water,  gas,  electric  and  other  utility
         charges,   business  and  other  license  fees  and  taxes,  merchants'
         association  dues,  rental  payments  under any  leases,  any  customer
         refunds  for hearing  aids  delivered  prior to Closing,  and all other
         operating   liabilities   (including  legal,   accounting,   and  other
         professional  fees and  expenses  incurred  in the  ordinary  course of
         business),  and vendor accounts  payable.  The parties  anticipate that
         computed  on this  basis  Company  will  have a  negative  Net  Working
         Capital.

                  (b) As promptly as practicable  following the Closing,  but in
         no  event  later  than  45  days  thereafter  (the  "45-Day   Period"),
         Shareholder  and  HealthCare  shall  cooperate  in preparing a mutually
         agreeable  statement of the Net Working  Capital  which shall set forth
         the  computation  and  components  thereof in  reasonable  detail  (the
         "Statement of Net Working Capital").

                  (c) On the fifteenth day after the date on which the Statement
         of Net  Working  Capital is  completed  (or such  earlier  date as such
         statement is mutually  agreed upon by  Shareholder  and  HealthCare  in
         writing),  (i) in the  event  that the Net  Working  Capital  exceeds a
         negative  $20,000,  then HealthCare  shall pay to Shareholder an amount
         equal to the excess,  or (ii) in the event that the Net Working Capital
         is  less  than  a  negative  $20,000,  then  Shareholder  shall  pay to
         HealthCare  the amount by which the Net Working  Capital is less than a
         negative $20,000.

         1.8 SHAREHOLDER  LOANS. As of the date hereof,  the Company is indebted
to the  Shareholder  as set forth on  SCHEDULE  1.8.  Notwithstanding  any other
provision of this Agreement,  the Shareholder shall have the option, on or prior
to the  Closing,  to (i)  contribute  such  indebtedness  to the  capital of the
Company or (ii) cause the Company to repay such  indebtedness  to the extent the
Company has funds available for such purpose.

                                   ARTICLE II

"Closing") shall occur on December 2, 1996, or on such other date as the parties
may mutually agree.  Notwithstanding  the foregoing,  HealthCare  shall have the
right to postpone the Closing for up to 90 days if, in its judgment,  it becomes
necessary  to do  so  as a  result  of  requirements  of  the  securities  laws,
regulations,  or rules of the Province of Alberta,  the Alberta Stock  Exchange,
United  States,  state of Washington or state of  California.  The Closing shall

                  HealthCare Shares received in the Merger that would reduce the
                  Shareholder's  ownership of  HealthCare  Shares to a number of
                  shares having a value,  as of the date of the Merger,  of less
                  than  50  percent  of  the  value  of  all  of  the   formerly
                  outstanding stock of the Company as of the same date.

                  the Company immediately prior to the Merger.

                           (iii) The  liabilities  of the Company  assumed by HC
                  Subsidiary and the liabilities to which the transferred assets
                  of the Company are subject were incurred by the Company in the
                  ordinary course of its business.

                           (iv) The Company,  and the Shareholder will pay their
                  respective  expenses,  if any, incurred in connection with the

                           (v) The  Company is not an  investment  companies  as

                  sum of the  liabilities  assumed  by HC  Subsidiary,  plus the
                  amount of liabilities, if any, to which the transferred assets
                  are subject.

         5.2      COVENANTS OF HEALTHCARE.

                  (a)  Following  the  Merger,  HC  Subsidiary  will  not  issue

         Code.

                  (b)  Following  the Merger,  HC  Subsidiary  will continue the

         HC Subsidiary will take any action  inconsistent with such treatment of
         the  Merger,  or which  would  cause the Merger to fail to qualify as a
         tax-free reorganization.

                  (e) The  Shareholder has provided  personal  guarantees or has
         otherwise  become  individually  liable with respect to certain leases,
         line of credit agreements,  purchase agreements with manufacturers,  or
         other  agreements for the benefit for the Company,  including,  without
         limitation,  those described on SCHEDULE 5.2(E).  Following the Merger,
         HealthCare  will use its best  efforts  to obtain  the  release  of the
         Shareholder from all such personal liabilities.  To the extent that any
         such release cannot be obtained, HealthCare will indemnify and hold the
         Shareholder  harmless  with respect to any loss,  cost,  or expense the
         Shareholder may incur as a result of not being released.

                                 SECURITIES LAWS

         6.1      SECURITIES LAWS.

                  (a) INVESTMENT REPRESENTATIONS.  The Shareholder represents to
         HealthCare as follows:

                           (i) The HealthCare  Shares are being acquired for her
                  own account and for  investment  only,  and not with a view to
                  the distribution of all or any part of the HealthCare  Shares,
                  and  the   acquisition  of  the   HealthCare   Shares  by  the
                  Shareholder  and  her  continued  holding  thereof  as  may be
                  required by law and the terms hereof are  consistent  with her
                  financial position.

                           (ii)  The  Shareholder  has had  access  to  complete
                  information regarding the business and finances of HealthCare,
                  has met and  discussed the business and finances of HealthCare
                  with  its  management   employees  to  the  extent  she  deems
                  necessary,  has received, read, and understood the contents of
                  the Healthcare Capital Corp.  Confidential Offering Memorandum
                  dated October 16, 1996 (the  "Offering  Memorandum"),  and the
                  Shareholder  believes she has received all the information she
                  considers  necessary or  appropriate  for deciding  whether to
                  receive the HealthCare Shares as consideration in the Merger.

                           (iii) The  Shareholder  can bear the economic risk of
                  receiving  the  HealthCare  Shares  as  consideration  in  the
                  Merger,  and has such knowledge and experience in financial or
                  business  matters that she is capable of evaluating the merits
                  and risks of receiving such shares.

                           (iv) The  Shareholder is an "accredited  investor" as
                  that term is defined in Rule 501 of  Regulation D  promulgated
                  by the  Securities  and  Exchange  Commission  pursuant to the
                  Securities Act of 1933, as a result of the following:

                                    (A) The  Shareholder  has an individual  net
                           worth, or joint worth with the Shareholder's  spouse,
                           which exceeds $1,000,000; and/or



                                                     - 22 -

                                    (B) The Shareholder has an individual income
                           in excess of  $200,000 in each of the two most recent
                           years or joint  income with  Shareholder's  spouse in
                           excess of  $300,000  in each of those years and has a
                           reasonable  expectation  of reaching  the same income
                           level in the current year.

                  or, if not an accredited  investor,  then the  Shareholder  by
                  reason of her business or financial experience or the business
                  or financial experience of her professional  advisers (who are
                  unaffiliated with and who are not compensated by HealthCare or
                  any  affiliate  or selling  agent of  HealthCare  directly  or
                  indirectly),  has the capacity to protect her own interests in
                  connection with the receipt of the HealthCare Shares.

                  (b) LIMITATIONS ON TRANSFER.  Except as expressly  provided in
         this  Agreement,  the  Shareholder  shall not,  directly or indirectly,
         offer or sell,  pledge,  transfer,  or otherwise  dispose of all or any
         portion  of the  HealthCare  Shares,  or  solicit  any  offer  to  buy,
         purchase,  or otherwise  acquire or take a pledge of all or any portion
         of the  HealthCare  Shares,  except (A) in the manner and to the extent
         described  in  (i)  a  registration   statement  in  effect  under  the
         Securities Act of 1933 (the "Act")  covering the HealthCare  Shares and
         as to which a prospectus  meeting the  requirements  of the Act is duly
         delivered  and  filed as  necessary  with any  state  agency or (ii) an
         opinion  of  counsel  for  the  Shareholder  reasonably  acceptable  to
         HealthCare,  which  opinion is in form and  substance  satisfactory  to
         counsel for HealthCare,  to the effect that such proposed offer,  sale,
         pledge,  transfer,  or  other  disposition  of  HealthCare  Shares  may
         lawfully be made without such registration, delivery or state filing or
         (B) pursuant to trades made on the Alberta Stock Exchange ("ASE") after
         90 days  following  the Closing  pursuant to Rule 904 of  Regulation  S
         under the Act. The Shareholder acknowledges that she has consulted with
         counsel   concerning  the  limited   availability  of  exemptions  from
         registration under the Act or exemptions from qualification under state
         securities laws and she understands  that she (i) may bear the economic
         risk of investment in the HealthCare Shares for an indefinite period of
         time because the HealthCare  Shares have not been registered  under the
         Act or qualified under state securities laws and, therefore,  cannot be
         sold unless they are subsequently registered under the Act or qualified
         under state  securities  laws or an exemption  from such  registration,
         such as that  contained  in Rule 904,  or from state  qualification  is
         available,  (ii) HealthCare is not obligated to register the HealthCare
         Shares under the Act or qualify them under state securities laws, (iii)
         that absent  registration,  the HealthCare Shares ordinarily may not be
         sold in the United  States for at least two years after the Closing and
         then  only in  accordance  with  Rule 144  under  the Act,  and  absent
         qualification  under  state  securities  laws may be subject to similar
         restrictions   and  (iv)  the  HealthCare   Shares  may  not  be  sold,
         transferred  or  otherwise  disposed  of in the  province  of  Alberta,
         Canada,  or traded through the facilities of the ASE for a period of 90
         days following the Closing.

                  (c) LEGENDS ON  CERTIFICATES.  Certificates  representing  the
         HealthCare Shares shall be endorsed with legends,  (i) substantially in
         the form set forth in SCHEDULE 6.1(C)



                                                     - 23 -

         hereto,  and (ii) to the effect that the  HealthCare  Shares may not be
         traded in Canada for 90 days following the Closing. HealthCare need not
         recognize any person other than the  Shareholder as having any interest
         in or to the  HealthCare  Shares unless the  acquisition  thereof shall
         have been made in compliance with Subsection  6.1(b) above.  HealthCare
         may issue appropriate stop transfer  instructions to the transfer agent
         for  the  HealthCare  Shares  to  prevent  transfers  in  violation  of
         Subsection 6.1(b) hereof.

                  (d)      REMOVAL OF LEGENDS.

                           (i) At any  time  while  the  HealthCare  Shares  are
                  registered  under  the Act,  HealthCare  shall,  upon  written
                  request,  cause the  certificates  representing the HealthCare
                  Shares to be reissued  free of all legends  and  withdraw  all
                  stop transfer  instructions.  Upon the termination of any such
                  registration,   if  the  Shareholder  owns  HealthCare  Shares
                  represented  by  a  certificate  without  such  legends,   the
                  Shareholder shall, upon written request,  promptly return such
                  certificate  to  HealthCare  for  reissue  for  a  certificate
                  endorsed with the legends  specified in, and otherwise subject
                  to, the provisions of Subsection 6.1(c). Three years after the
                  Closing,   HealthCare's   right  to  request   the  return  of
                  unlegended  certificates for previously  registered HealthCare
                  Shares shall  terminate  and  HealthCare  shall,  upon written
                  request of the Shareholder, cause any certificates bearing one
                  or more  legends  to be  reissued  free of  such  legends  and
                  withdraw all stop  transfer  instructions,  provided that Rule
                  144(k)  under the Act, or a comparable  rule,  is in effect in
                  substantially  its present form and the Shareholder  furnishes
                  to HealthCare  evidence  satisfactory  to  HealthCare  and its
                  counsel that she meets the requirements of such rule.

                           (ii) HealthCare shall, upon written request,  cause a
                  certificate  representing  all or a portion of the  HealthCare
                  Shares to be reissued free of all legends  (except as provided
                  in Section 1.5 hereof) and shall  withdraw  all stop  transfer
                  instructions  upon  the  provision  by  the  Shareholder  of a
                  declaration  to The R-M Trust  Company  as  transfer  agent in
                  substantially  the  form  set  forth  in  SCHEDULE  6.1(D)(II)
                  hereto.

         6.2      REGISTRATION UNDERTAKING.

                  (a) HealthCare  agrees that, if at any time from and after the
         Closing date and before the second  anniversary of such date, the board
         of directors of HealthCare shall authorize the filing of a registration
         statement under the Act for sale of HealthCare  shares by HealthCare in
         the United States, HealthCare will (i) promptly notify Shareholder that
         such  registration  statement  will be filed  and  that the  HealthCare
         Shares  which are then held by  Shareholder  will be  included  in such
         registration  statement  at her  request,  (ii)  subject  to  the  last
         sentence of this subsection (a), cause such  registration  statement to
         cover all  HealthCare  Shares which it has been so requested to include
         by  Shareholder,  provided such request is delivered to HealthCare  not
         later  than 20 days  after  such  notice  is given to  Shareholder  and
         specifies the number of HealthCare Shares to be included in



                                                     - 24 -

         the proposed  registration,  (iii) use  reasonable  efforts  subject to
         market  conditions  to cause  such  registration  statement  to  become
         effective  and remain  effective  and current for such period as may be
         necessary to permit the  underwriters  to complete the  distribution of
         the securities covered by the registration  statement, if such offering
         is an underwritten offering, or, if not, for such period, not in excess
         of 90 days,  as may be necessary for  Shareholder  to effect a proposed
         sale or other  distribution,  and (iv) take all other action  necessary
         under  any  federal  or state  law or  regulation  of any  governmental
         authority  (other than the state securities or blue sky laws) to permit
         the  shares  included  in  such  registration  statement  to be sold or
         otherwise  disposed of and will maintain such compliance with each such
         federal and state law and regulation of governmental  authority for the
         period necessary for the  underwriters or Shareholder,  as the case may
         be, to effect the proposed sale or other  disposition.  Notwithstanding
         the foregoing provisions,  if the registration  statement relates to an
         underwritten offering of HealthCare Shares and the managing underwriter
         shall  inform  in  writing  HealthCare  and  Shareholder  and any other
         holders of HealthCare  Shares  requesting  such  registration  that the
         managing underwriter believes that the number of shares requested to be
         included in such registration  would  materially,  adversely affect its
         ability to effect such offering,  then  HealthCare will include in such
         registration  the number of  HealthCare  Shares which  HealthCare is so
         advised  can be sold in (or  during  the  time  of)  such  offering  as
         follows:  first,  all shares  proposed by HealthCare to be sold for its
         own  account,  and,  second,  such  HealthCare  Shares  requested to be
         included  in such  registration,  pro  rata by  Shareholder  and  other
         holders of  HealthCare  Shares on the basis of the number of HealthCare
         Shares  so  proposed  to be  sold  and  so  requested  to be  included;
         PROVIDED,  HOWEVER,  that HealthCare shall be obligated to register any
         HealthCare Shares so excluded from the registration  statement pursuant
         to a registration  statement filed 90 days after the  effectiveness  of
         such initial  registration  statement or such greater number of days as
         may be specified in "lock-up" agreements entered into with the managing
         underwriter.

                  (b) Whenever HealthCare is required pursuant to the provisions
         of this  Section  6.2 to include  HealthCare  Shares in a  registration
         statement,   HealthCare   shall  (i)  furnish   Shareholder   and  each
         underwriter of such HealthCare Shares with such copies of a prospectus,
         including the preliminary  prospectus,  conforming to the Act (and such
         other documents as Shareholder and each such underwriter may reasonably
         request) in order to facilitate the sale or  distribution of HealthCare
         Shares,  (ii)  use  its  best  efforts  to  register  or  qualify  such
         HealthCare Shares under the blue sky laws (to the extent applicable) of
         such  jurisdiction or jurisdictions as Shareholder and each underwriter
         of HealthCare Shares being sold shall reasonably request and (iii) take
         such other  actions as may be  reasonably  necessary  or  advisable  to
         enable the Shareholders and such underwriters to consummate the sale or
         distribution  in such  jurisdiction  or  jurisdictions  in  which  such
         holders shall have reasonably  requested that the HealthCare  Shares be
         sold.   Shareholder   shall  furnish  to  HealthCare  in  writing  such
         information relating to herself as HealthCare may reasonably request in
         connection with the preparation of such registration statement.

                  (c) HealthCare  shall pay all expenses  incurred in connection
         with any  registration  or other action  pursuant to the  provisions of
         this Section 6.2,  other than  underwriting  discounts  and  applicable
         transfer taxes  relating to the  HealthCare  Shares sold by Shareholder
         and attorney fees and expenses of Shareholder.

                  (d)   HealthCare   agrees  to  indemnify   and  hold  harmless
         Shareholder  from and  against  any and all  losses,  claims,  damages,
         liabilities  or actions,  joint or several,  to which  Shareholder  may
         become subject under the Act for any legal or other expenses (including
         the  cost of any  investigation  and  preparation)  incurred  by her in
         connection with any litigation or threatened litigation, whether or not
         resulting in any  liability,  but only insofar as such losses,  claims,
         damages,  liabilities  or actions arise out of, or are based upon,  (i)
         any untrue  statement or alleged  untrue  statement of a material  fact
         contained in any  registration  statement  pursuant to which HealthCare
         Shares   were   registered   under  the  Act   (hereinafter   called  a
         "Registration  Statement"),   any  preliminary  prospectus,  the  final
         prospectus  or  any   amendment  or  supplement   thereto  (or  in  any
         application or document filed in connection  therewith) or any document
         filed by HealthCare in any jurisdiction in order to register or qualify
         the HealthCare Shares under the securities laws thereof or the omission
         or alleged  omission to state  therein a material  fact  required to be
         stated  therein or necessary  to make the  statements  therein,  in the
         light of the circumstances  under which they were made, not misleading,
         or (ii) the employment by HealthCare of any device,  scheme or artifice
         to defraud,  or the  engaging  by  HealthCare  in any act,  practice or
         course  of  business  which  operates  or would  operate  as a fraud or
         deceit,  or any conspiracy with respect  thereto,  in which  HealthCare
         shall  participate,  in connection with the issuance and sale of any of
         the  HealthCare  Shares;  PROVIDED,  HOWEVER  that  (i)  the  indemnity
         agreement  contained  in  this  Subsection  (d)  shall  not  extend  to
         Shareholder in respect of any such losses, claims, damages, liabilities
         or actions  arising out of, or based upon any such untrue  statement or
         alleged untrue statement,  or any such omission or alleged omission, if
         such  statement or omission was based upon and made in conformity  with
         information   furnished  in  writing  to  HealthCare   by   Shareholder
         specifically  for  use in  connection  with  the  preparation  of  such
         Registration   Statement,   any  final   prospectus,   any  preliminary
         prospectus  or any such  amendment  or  supplement  thereto  (or in any
         application  or document  filed in  connection  therewith)  or document
         filed  in  any  jurisdiction  in  order  to  register  or  qualify  the
         HealthCare Shares under the securities laws thereof.  HealthCare agrees
         to pay any legal and other  expenses  for which it is liable under this
         Subsection (d) from time to time (but not more frequently than monthly)
         within 30 days after its receipt of a bill therefor.

                  (e) Shareholder  will indemnify and hold harmless  HealthCare,
         its  directors,  its  officers  who shall have signed the  Registration
         Statement and each person,  if any, who controls  HealthCare within the
         meaning of Section 15 of the



                                                     - 26 -

         Act to the same extent as the foregoing indemnity from HealthCare,  but
         in each case to the extent, and only to the extent,  that any statement
         in  or  omission  from  or  alleged  omission  from  such  Registration
         Statement,  any final  prospectus,  any  preliminary  prospectus or any
         amendment  or  supplement  thereto (or in any  application  or document
         filed in connection therewith) or document filed in any jurisdiction in
         order to register or qualify the HealthCare Shares under the securities
         laws thereof was made in reliance upon information furnished in writing
         to HealthCare by Shareholder  specifically  for use in connection  with
         the preparation of the Registration Statement,  any final prospectus or
         the preliminary  prospectus or any such amendment or supplement thereto
         (or in any  application or document  filed in connection  therewith) or
         document filed in any  jurisdiction in order to register or qualify the
         HealthCare Shares under the securities laws thereof; PROVIDED, HOWEVER,
         that the obligation of Shareholder  to indemnify  HealthCare  under the
         provisions  of this  Subsection  (e) shall be limited to the product of
         the  number of  HealthCare  Shares  being sold by  Shareholder  and the
         market price of HealthCare Shares on the date of the sale to the public
         of these  HealthCare  Shares.  Shareholder  agrees to pay any legal and
         other  expenses for which she is liable under this  Subsection (e) from
         time to time  (but not more  frequently  than  monthly)  within 30 days
         after receipt of a bill therefor.

                  (f) If any  action is  brought  against a person  entitled  to
         indemnification  pursuant to the foregoing  Subsections (d) and (e) (an
         "indemnified  party")  in  respect  of which  indemnity  may be  sought
         against a person granting  indemnification  (an  "indemnifying  party")
         pursuant to such Subsections (d) and (e), such indemnified  party shall
         promptly notify such indemnifying  party in writing of the commencement
         thereof;  but the omission so to notify the  indemnifying  party of any
         such action shall not release the indemnifying party from any liability
         it or she may have to such indemnified  party otherwise than on account
         of the indemnity agreement contained in Subsections (d) and (e) of this
         Section 6.2. In case any such action is brought  against an indemnified
         party and it or she notifies an indemnifying  party of the commencement
         thereof,  the  indemnifying  party  against which a claim is to be made
         will be entitled to participate  therein at its, his or her own expense
         and, to the extent that it or she may wish, to assume at its or her own
         expense the defense thereof,  with counsel  reasonably  satisfactory to
         such indemnified party;  PROVIDED,  HOWEVER, that (i) if the defendants
         in  any  such  action  include  both  the  indemnified  party  and  the
         indemnifying  party and the  indemnifying  party shall have  reasonably
         concluded based upon advice of counsel that there may be legal defenses
         available  to it,  she  and/or  other  indemnified  parties  which  are
         different  from or  additional  to those  available to the  indemnified
         party,  the  indemnified  party shall have the right to select separate
         counsel to assume such legal  defenses and otherwise to  participate in
         the  defense  of such  action on behalf  of such  indemnified  party or
         parties and (ii) in any event, the indemnified  party shall be entitled
         to have counsel chosen by such  indemnified  party  participate in, but
         not conduct, the defense at the expense of the indemnifying party. Upon
         receipt of notice from the indemnifying



                                                     - 27 -

<PAGE>



         party to such indemnified party of its or her election so to assume the
         defense  of such  action  and  approval  by the  indemnified  party  of
         counsel,  the indemnifying party will not be liable to such indemnified
         party  under  this  Section  6.2  for  any  legal  or  other   expenses
         subsequently  incurred by such indemnified party in connection with the
         defense  thereof unless (i) the  indemnified  party shall have employed
         such counsel in connection  with the  assumption  of legal  defenses in
         accordance  with proviso (i) to the next  preceding  sentence (it being
         understood,  however,  that the indemnifying  party shall not be liable
         for  the  expenses  of  more  than  one  separate  counsel),  (ii)  the
         indemnifying   party  shall  not  have  employed   counsel   reasonably
         satisfactory  to the  indemnified  party to represent  the  indemnified
         party within a  reasonable  time after  notice of  commencement  of the
         action or (iii) the indemnifying party has authorized the employment of
         counsel for the  indemnified  party at the expense of the  indemnifying
         party. An indemnifying  party shall not be liable for any settlement of
         any action or proceeding effected without its written consent.

                  (g) In order to provide for just and equitable contribution in
         circumstances  in  which  the  indemnity   agreement  provided  for  in
         Subsections  (d) and  (e) of  this  Section  6.2 is  unavailable  to an
         indemnified  party  in  accordance  with  its  terms,   HealthCare  and
         Shareholder shall contribute to the aggregate losses,  claims,  damages
         and  liabilities,   of  the  nature   contemplated  by  said  indemnity
         agreement,  incurred by HealthCare and Shareholder, in such proportions
         as are  appropriate  to  reflect  the  relative  benefits  received  by
         HealthCare and Shareholder from any offering of the HealthCare  Shares;
         PROVIDED,  HOWEVER,  that  if  such  allocation  is  not  permitted  by
         applicable  law or if the  indemnified  party failed to give the notice
         required  under  Subsection  (f) of this Section 6.2, then the relative
         fault of HealthCare and  Shareholder in connection  with the statements
         or  omissions  which  resulted  in such  losses,  claims,  damages  and
         liabilities  and  other  relevant  equitable   considerations  will  be
         considered together with such relative benefits.

                  (h) The respective  indemnity and  contribution  agreements by
         HealthCare and Shareholder in Subsections (d), (e), (f) and (g) of this
         Section  6.2  shall  remain  operative  and in full  force  and  effect
         regardless  of  (i)  any  investigation   made  by  Shareholder  or  by
         HealthCare or any  controlling  person of HealthCare or any director or
         any  officer of  HealthCare,  (ii)  payment  for any of the  HealthCare
         Shares or (iii) any  termination of this  Agreement,  and shall survive
         the delivery of the HealthCare Shares, and any successor of HealthCare,
         or of  Shareholder,  or of any person who controls  HealthCare,  as the
         case may be,  shall  be  entitled  to the  benefit  of such  respective
         indemnity and  contribution  agreements.  The respective  indemnity and
         contribution  agreements by  HealthCare  and  Shareholder  contained in
         Subsections  (d),  (e),  (f) and (g) of this  Section  6.2  shall be in
         addition  to  any  liability  which   HealthCare  and  Shareholder  may
         otherwise have.

              CONDITIONS PRECEDENT TO THE SHAREHOLDER'S OBLIGATIONS

                  (a) EMPLOYMENT  AGREEMENT.  HC Subsidiary  shall have executed
         and delivered to Shareholder an Employment  Agreement  substantially in
         the form of SCHEDULE 7.6(B) hereto.

                                   ARTICLE IX
                  INDEMNIFICATION; SURVIVAL OF REPRESENTATIONS

         9.1  INDEMNIFICATION  BY  SHAREHOLDER.  Shareholder  hereby  agrees  to
indemnify,  defend, and hold HealthCare harmless from and against all Claims (as
defined  below)  asserted  against,  resulting to,  imposed upon, or incurred by
HealthCare  directly or  indirectly  by reason of,  arising out of, or resulting
from (a) the  inaccuracy  or breach of any  representation  or  warranty  of the
Shareholder  contained in or made pursuant to this Agreement,  or (b) the breach
of any covenant of the Shareholder contained in this Agreement.  As used in this
Section 9.1,  the term "Claim"  shall  include all losses,  damages,  judgments,
awards,   settlements,   costs,  and  expenses   (including  without  limitation
penalties,  court costs, and attorneys fees and expenses at trial and on appeal)
awarded by the arbitrator or arbitrators pursuant to Section 10.12 hereof.

         9.2   INDEMNIFICATION  BY  HEALTHCARE.   HealthCare  hereby  agrees  to
indemnify, defend, and hold harmless the Shareholder from and against all Claims
(as defined in Section 9.1) asserted  against,  resulting  to,  imposed upon, or
incurred by the Shareholder directly or indirectly by reason of, arising out of,
or resulting from (a) the inaccuracy or breach of any representation or warranty
of HealthCare contained in or made pursuant to this Agreement, or (b) the breach
of any covenant of HealthCare contained in this Agreement.

         9.3  NOTICE;  DEFENSE  OF  CLAIMS.  If a claim is to be made by a party
entitled   to   indemnification   hereunder,   the   party   entitled   to  such
indemnification  shall give written notice to the indemnifying party immediately
after the party entitled to indemnification becomes aware of any fact, condition
or event  which  may give  rise to a matter  for  which  indemnification  may be
sought; provided that the failure of any indemnified party to give timely notice
shall not affect the rights to  indemnification  hereunder  except to the extent
that the indemnifying party  demonstrates  actual damage caused by such failure.
If any lawsuit or enforcement  action is filed against any party entitled to the
benefit of indemnity hereunder,  and if the indemnifying party shall acknowledge
in  writing  to the  indemnified  party  that the  indemnifying  party  shall be
obligated  under the terms of its indemnity  hereunder in  connection  with such
lawsuit,  action or claim, then the indemnifying party shall be entitled,  if it
or she so elects,  to take  control of the  defense  and  investigation  of such
lawsuit or action and to employ and engage attorneys of its or her own choice to
handle and defend the same, at the  indemnifying  party's cost, risk and expense
provided that the  indemnifying  party and its or her counsel shall proceed with
diligence and in good faith with respect  thereto.  The indemnified  party shall
cooperate  in all  reasonable  respects  with the  indemnifying  party  and such
attorneys in the investigation, trial and defense



                                                     - 31 -

of such lawsuit or action and any appeal arising therefrom;  provided,  however,
that the  indemnified  party  may,  at its or her own cost,  participate  in the
investigation,  trial and  defense  of such  lawsuit  or action  and any  appeal
arising therefrom.

         9.4 SURVIVAL OF  REPRESENTATIONS.  All  representations  and warranties
made by the  parties  in this  Agreement  are  made  only as of the date of this
Agreement but will survive the consummation of the transactions  contemplated by
this  Agreement  for a period  ending 90 days after the second  fiscal  year end
(July 31) of HC  Subsidiary  which  occurs  after the  Closing  (except  for the
representations  and  warranties  of the  Shareholder  set forth in Section 3.11
hereof which shall expire 90 days after the  applicable  statutes of  limitation
shall have run with  respect to all tax  returns  filed by the  Company  for all
periods ended on or before the Closing) after which all such representations and

         10.12             RESOLUTION OF DISPUTES.

                  (a) ARBITRATION. Any dispute, controversy or claim arising out
         of or relating to this  Agreement or the  performance by the parties of
         its terms  shall be settled by binding  arbitration  held in San Diego,
         California,  in accordance with the Commercial Arbitration Rules of the
         American Arbitration Association then in effect, except as specifically
         otherwise   provided  in  this  Section  10.12.   Notwithstanding   the
         foregoing, HealthCare, in its discretion, apply to a court of competent
         jurisdiction  for  equitable  relief from any  violation or  threatened
         violation of the provisions of the Shareholder under any noncompetition
         and confidentiality agreements executed pursuant to this Agreement.

                  (b) ARBITRATORS. Following thirty (30) days' written notice by
         any party of intention to invoke arbitration, any dispute arising under
         this  Agreement  which  have  not  been  mutually   resolved  shall  be
         determined  by a single  arbitrator  upon whom the parties agree or, if
         the  parties  cannot  agree  on a  single  arbitrator  within  five (5)
         business days following such thirty (30) day period, then by a board of
         three (3) arbitrators,  which  arbitrator(s) shall be selected for each
         such  controversy so arising  hereunder.  If three (3)  arbitrators are
         necessary,  each party shall have the right to pick one  arbitrator and
         the two  arbitrators  so chosen  shall have the right to select a third
         arbitrator.  Any  party  who is  unable  or  unwilling  to so select an
         arbitrator in a timely  manner,  shall forfeit its right to participate
         in the  selection  process.  If a  selected  arbitrator  is  unable  or
         unwilling  to act,  or if for any other  reason an  appointment  of the
         requisite  number or  arbitrators  cannot be made,  then any party,  on
         behalf of all the parties,  may request appointment of arbitrator(s) by
         the presiding judge of the federal courts located in the
                   District of California.

                  (c) PROCEDURES;  NO APPEAL. The arbitrator(s) shall allow such
         discovery  as  the  arbitrator(s)   determine   appropriate  under  the
         circumstances  and  shall  resolve  the  dispute  as  expeditiously  as
         practicable,  and if reasonably practicable,  within 120 days after the
         selection  of the  arbitrator(s).  The  arbitrator(s)  shall  give  the
         parties written notice of the decision,  with the reasons  therefor set
         out, and shall have thirty (30) days



                                                     - 35 -

<PAGE>



         thereafter  to  reconsider  and modify  such  decision  if any party so
         requests  within  ten (10) days  after the  decision.  Thereafter,  the
         decision   of  the   arbitrator(s)   shall  be  final,   binding,   and
         nonappealable   with  respect  to  all  persons,   including   (without
         limitation)  persons who have failed or refused to  participate  in the
         arbitration process.

                  (d) AUTHORITY. The arbitrator(s) shall have authority to award
         relief  under  legal or  equitable  principles,  including  interim  or
         preliminary relief, and to allocate responsibility for the costs of the
         arbitration and to award recovery of attorney fees and expenses in such
         manner as is determined to be appropriate by the arbitrator(s).

                  (e) ENTRY OF JUDGMENT. Judgment upon the award rendered by the
         arbitrator(s)  may be  entered  in any  court  having in  personam  and
         subject matter  jurisdiction.  The  Shareholder  and HealthCare  hereby
         submit to the in personam  jurisdiction of the federal and state courts
         in California for the purpose of confirming any such award and entering
         judgment thereon.

                  (f) CONFIDENTIALITY. All proceedings under this Section 10.12,
         and  all  evidence  given  or  discovered  pursuant  hereto,  shall  be
         maintained in confidence by all parties.

                  (g)   CONTINUED   PERFORMANCE.   The  fact  that  the  dispute
         resolution  procedures  specified in this Section 10.12 shall have been
         or may be  invoked  shall not  excuse  any party  from  performing  its
         obligations  under this Agreement,  and during the pendency of any such
         procedure  all  parties  shall  continue  to perform  their  respective
         obligations  in good  faith,  subject to any rights to  terminate  this
         Agreement that may be available to any party.

         10.13  GOVERNING  LAW. This Agreement may not be modified or terminated
orally, and shall be construed and interpreted  according to the internal law of
the state of  California,  excluding any choice of law rules that may direct the
application of the laws of another jurisdiction.

         10.14  COUNTERPARTS.  This  Agreement  may be  executed  by the parties
hereto in separate  counterparts,  each of which when so executed and  delivered
shall be an original,  but all such counterparts  shall together  constitute one
and the same  instrument.  Each  counterpart  may  consist of a number of copies
hereof each signed by less than all, but together  signed by all, of the parties
hereto.

         10.15 ENTIRE  AGREEMENT.  This Agreement  (including the Schedules) and
the  agreements,  certificates  and other  documents  delivered  pursuant hereto
contain  the  entire   agreement   between  the  parties  hereto.   All  parties
collaborated  in the  preparation  of this Agreement and it has been reviewed by
attorneys for each party.  No one party should be  considered  the author of any
specific language for purposes of legal presumptions.

         10.16 FURTHER ASSURANCES. Both before and after the Closing, each party
will  cooperate  in good faith  with the  others  and will take all  appropriate
action and execute any documents,



                                                     - 36 -

instruments,  or  conveyances  of any kind that may be  reasonable  necessary or
desirable to carry out any of the transactions contemplated hereunder.

         IN  WITNESS  WHEREOF,  the  parties  hereto  have  duly  executed  this
Agreement effective as of the date first above written.

         1.5  POST-CLOSING  ADJUSTMENTS  TO NOTES.  On the payment  dates of the
Notes,  Purchaser shall pay to the Sellers the respective principal and interest
due them less the set-offs (if any) which result from the following provisions.

                  (a) EARN-OUT.  The income of the business  being acquired from
         the Company hereunder (the "Business")  shall be separately  determined
         for each of the three  12-month  periods  ending on November  30, 1997,
         1998 and 1999 (the "Earn-Out  Years").  Such income shall be determined
         in accordance with generally accepted accounting  principles applied on
         a basis consistent with Purchaser's  accounting  practices.  If for any
         Earn-Out  Year the  income  of the  Business  before  interest,  taxes,
         depreciation  and   amortization  but  after  the  corporate   overhead
         allocation specified below falls below an amount equal to 20 percent of
         the net revenues of the Business for such year, then for each dollar of
         the  shortfall  one  dollar  shall  be  set-off  pro rata  against  the
         principal  and accrued  interest  due on the Notes.  The total  maximum
         reduction on the Notes for any Earn-Out Year,  pursuant to this Section
         1.5(a),  shall be $12,500.  For purposes of this Section  1.5(a),  "net
         revenues"  shall mean gross revenues less returns and  allowances.  The
         corporate overhead  allocation to be charged against the Business shall
         equal 6 percent of its net revenues.

                  (b)  ACCOUNTS  RECEIVABLE.  On the  200th  day  following  the
         Closing,  Purchaser  shall  set-off pro rata against the  principal and
         interest due on Notes the total amount of accounts receivable reflected
         on the  Statement  of Net Working  Capital  (as  defined in  subsection
         1.6(b)  below)  net of the  allocable  portion of the  reserve  for bad
         debts, which remain uncollected as of such date. Upon such set-off, the
         uncollected accounts shall be assigned to Sellers.  During such 200-day
         period,  Sellers  may  participate  in the  collection  process of such
         accounts receivable.

                  (c) LIABILITIES.  To the extent that the Company has long-term
         liabilities, including any amounts owed to Sellers which will be repaid
         at Closing pursuant to Section 5.2(b) hereof,  in excess of $100,000 as
         of the Closing  date,  each dollar of such excess  shall be set-off pro
         rata  against the  principal  amounts of the Notes  effective as of the
         Closing date.

         1.6      NET WORKING CAPITAL ADJUSTMENT.

                  (a) For  purposes of this  Agreement,  "Net  Working  Capital"
         shall equal (i) cash, money market accounts,  accounts  receivable (net
         of reasonable  provisions for doubtful  accounts),  inventory,  prepaid
         expenses and all other current assets of the Company as of Closing less
         (ii) all current  liabilities  of the Company as of Closing,  including
         but not limited to liabilities for inventory, office supplies, ordinary
         compensation payables,  employee benefits and taxes (including, but not
         limited to, accrued paid time off for vacation and sick leave), bonuses
         (including all related payroll taxes and employee  benefits),  personal
         and real  property  taxes,  water,  gas,  electric  and  other  utility
         charges,   business  and  other  license  fees  and  taxes,  merchants'
         association  dues,  rental  payments  under any  leases,  any  customer
         refunds for hearing aids delivered

         prior to Closing, and all other operating liabilities (including legal,
         accounting,  and other  professional  fees and expenses incurred in the
         ordinary course of business), and vendor accounts payable.

                  (b) As promptly as practicable  following the Closing,  but in
         no event later than 45 days  thereafter,  Sellers and  Purchaser  shall
         cooperate  in  preparing  a  mutually  agreeable  statement  of the Net
         Working  Capital which shall set forth the  computation  and components
         thereof in reasonable detail (the "Statement of Net Working Capital").

                  (c) On the fifteenth day after the date on which the Statement
         of Net  Working  Capital is  completed  (or such  earlier  date as such
         statement is mutually agreed upon by Sellers and Purchaser in writing),
         (i) in the event that the Net Working  Capital  exceeds  $15,000,  then
         Purchaser  shall pay to Sellers pro rata an amount equal to the excess,
         or (ii) in the event that Net  Working  Capital  is less than  $15,000,
         then  Sellers  shall pay to  Purchaser,  pro rata,  the  amount of such
         deficiency.

         The party obligated to make the adjusting  payment required pursuant to
this  paragraph  shall have the option  either to make the payment in cash or by
delivering  a  promissory  note due and payable not more than 180 days after its
date, with interest at the rate of 9 percent per annum. If Sellers are obligated
to make the  adjusting  payment,  Sellers  shall also have the option to request
that the amounts they are  obligated to pay  Purchaser be offset  against  their
respective Notes.

policies and practices.  The books of the Company correctly record the principal
balance of all accounts receivable and each of the security instruments securing
any account receivable, if any, constitutes a valid lien in favor of the Company
upon the property which it describes,  and is enforceable by the Company and its
transferees.  The  reserves  for  doubtful  accounts  shown or  reflected on the
Financial  Statements  are adequate  and were  calculated  consistent  with past
practice.

         3.23  INVENTORY.  The  inventories  of the Company are of a quality and
quantity  usable  and  salable  in  the  ordinary  course  of  business,  have a
commercial  value at least  equal to the value shown on the  Company's  books of
account.

                  efforts to avoid any act, or any  omission  to act,  which may

                  obligation,  or any  breach of any  representation,  warranty,
                  covenant or agreement made by the Sellers.

                  (a) RELEASE OF SELLERS' PERSONAL  GUARANTEES.  Certain Sellers
         have provided personal guarantees or have otherwise become individually
         liable  with  respect to  certain  leases,  line of credit  agreements,
         purchase agreements with manufacturers, or other



                                                     - 17 -

         agreements  for  the  benefit  for  the  Company,  including,   without
         limitation,  those described on SCHEDULE 5.2(A). Following the Closing,
         Purchaser  will use its best  efforts  to  obtain  the  release  of the
         Sellers from all such personal liabilities. To the extent that any such
         release  cannot be  obtained,  Purchaser  will  indemnify  and hold the
         Sellers harmless with respect to any loss, cost, or expense the Sellers
         may incur as a result of not being released.  Notwithstanding any other
         provision of this Agreement,  Sellers may cancel as of the Closing date
         any  continuing  guaranties  with  respect to future  purchases  by the
         Company.

                  (b) REPAYMENT OF SELLERS'  LOANS.  As of the date hereof,  the
         Company is indebted  to the  Sellers as set forth on  SCHEDULE  5.2(B).
         Notwithstanding  any other  provision  of this  Agreement,  the Sellers
         shall have the option,  prior to the Closing,  to (i)  contribute  such
         indebtedness to the capital of the Company or (ii) cause the Company to
         repay such  indebtedness  to the extent the Company has funds available
         for such purpose.  In the event any  indebtedness of the Company to the
         Sellers  remains unpaid as of the Closing date,  Purchaser shall pay or
         contribute  sufficient  funds to the  Company to permit the  Company to
         repay such indebtedness in full at the Closing.

                                   ARTICLE VI
                 CONDITIONS PRECEDENT TO PURCHASER'S OBLIGATIONS

correct  in all  material  respects  at and as of the  Closing  as  though  such
representations and warranties were made as of the Closing.

respects  performed and complied with all of their  agreements  and  obligations
under this Agreement which are to be performed or complied with by them prior to

before any court or any  governmental  authority  shall have been  commenced  or
threatened, against Purchaser, the Company or any of the affiliates, officers or

transactions contemplated hereby, or questioning the validity or legality of any
such  transactions,  or seeking  damages in  connection  with,  or imposing  any

         8.1      INDEMNIFICATION BY THE SELLERS.

                  (a) The Sellers  hereby agree to indemnify,  defend,  and hold
         Purchaser  (and  its  directors,  officers,  shareholders,   employees,
         affiliates,  agents and assigns)  harmless  from and against all Claims
         (as defined  below)  asserted  against,  resulting to, imposed upon, or
         incurred by Purchaser  directly or indirectly by reason of, arising out
         of,  or   resulting   from  (a)  the   inaccuracy   or  breach  of  any
         representation or warranty of the Sellers contained in or made pursuant
         to this Agreement or in any of the documents delivered pursuant hereto,
         or (b) the non-performance or breach of any covenant, term or provision
         to be performed by the Sellers contained in this Agreement or in any of
         the documents delivered pursuant hereto. The indemnification obligation
         of Sellers  hereunder  is with respect to the full amount of the Claims
         (as defined  below).  As used in this  Article  VIII,  the term "Claim"
         shall include any and all losses, liabilities,  damages,  deficiencies,

                  and




                                                     - 20 -

                           (ii) no Seller shall be responsible for  indemnifying
                  Purchaser  in the  aggregate  for any  amount in excess of the
                  portion of the Purchase Price received by such Seller.

                  (b) Notwithstanding  paragraph (a) above,  Purchaser shall not
         have the right to  indemnification  with respect to Claims arising from
         the inaccuracy or breach of any  representation  or warranty of Sellers
         to the extent that Purchaser had actual knowledge of such inaccuracy or
         breach prior to Closing.

                  (c)  Purchaser  may,  at its  option,  offset,  by  notice  to
         Sellers,  any amount due from Sellers  pursuant to the  indemnification
         provisions of this  Agreement  against any payment due to Sellers under
         the Notes, any non-compete agreement, or otherwise. If Sellers disputes
         the validity of the offset, the matter shall be resolved by arbitration
         under  Section  9.12.  Any  undisputed  portion  shall  be  paid to the
         obligee.

         8.2 INDEMNIFICATION BY PURCHASER. Purchaser hereby agrees to indemnify,
defend,  and hold  harmless  the Sellers  from and  against all Claims  asserted
against,  resulting to,  imposed  upon,  or incurred by the Sellers  directly or
indirectly by reason of, arising out of, or resulting from (a) the inaccuracy or
breach of any  representation  or warranty  of  Purchaser  contained  in or made
pursuant to this Agreement or in any of the documents delivered pursuant hereto,
or (b) the  non-performance  or breach of any covenant,  term or provision to be
performed by Purchaser  contained in this  Agreement or in any of the  documents
delivered pursuant hereto. The indemnification obligation of Purchaser hereunder
is with respect to the full amount of the Claims.

         8.3  NOTICE;  DEFENSE  OF  CLAIMS.  If a claim is to be made by a party
entitled   to   indemnification   hereunder,   the   party   entitled   to  such
indemnification  shall give written notice to the indemnifying party immediately
after the party entitled to indemnification becomes aware of any fact, condition
or event  which  may give  rise to a matter  for  which  indemnification  may be
sought; provided that the failure of any indemnified party to give timely notice
shall not affect the rights to  indemnification  hereunder  except to the extent
that the indemnifying party  demonstrates  actual damage caused by such failure.
If any lawsuit or enforcement  action is filed against any party entitled to the
benefit of indemnity hereunder,  and if the indemnifying party shall acknowledge
in  writing  to the  indemnified  party  that the  indemnifying  party  shall be
obligated  under the terms of its indemnity  hereunder in  connection  with such
lawsuit,  action or claim, then the indemnifying party shall be entitled,  if it
so elects,  to take control of the defense and  investigation of such lawsuit or
action and to employ and engage attorneys of its own choice to handle and defend
the same, at the  indemnifying  party's cost, risk and expense provided that the
indemnifying  party and its counsel  shall  proceed with  diligence  and in good
faith with  respect  thereto.  The  indemnified  party  shall  cooperate  in all
reasonable  respects  with the  indemnifying  party  and such  attorneys  in the
investigation,  trial and  defense  of such  lawsuit  or action  and any  appeal
arising therefrom; provided, however, that the indemnified party may, at its own
cost,  participate  in the  investigation,  trial and defense of such lawsuit or
action and any appeal arising therefrom.

         9.12     RESOLUTION OF DISPUTES.

                  (a) ARBITRATION. Any dispute, controversy or claim arising out
         of or relating to this  Agreement or the  performance by the parties of
         its terms shall be settled by binding  arbitration held in Albuquerque,
         New Mexico, in accordance with the Commercial  Arbitration Rules of the
         American Arbitration Association then in effect, except as specifically
         otherwise provided in this Section 9.12. Notwithstanding the foregoing,
         Purchaser,  in its  discretion,  may  apply  to a  court  of  competent
         jurisdiction  for  equitable  relief from any  violation or  threatened
         violation of the provisions of the Sellers under any noncompetition and
         confidentiality agreements executed pursuant to this Agreement.

                  (b)  ARBITRATORS.  If the matter in controversy  (exclusive of
         attorney fees and expenses) shall appear,  as at the time of the demand
         for arbitration,  to exceed Fifty Thousand Dollars ($50,000),  then the
         panel to be  appointed  shall  consist  of three  neutral  arbitrators,
         otherwise one neutral arbitrator.

                  (c) PROCEDURES;  NO APPEAL. The arbitrator(s) shall allow such
         discovery  as  the  arbitrator(s)   determine   appropriate  under  the
         circumstances  and  shall  resolve  the  dispute  as  expeditiously  as
         practicable,  and if reasonably practicable,  within 120 days after the
         selection  of the  arbitrator(s).  The  arbitrator(s)  shall  give  the
         parties written notice of the decision,  with the reasons  therefor set
         out,  and shall have  thirty (30) days  thereafter  to  reconsider  and
         modify  such  decision  if any party so  requests  within ten (10) days
         after the decision. Thereafter, the decision of the arbitrator(s) shall
         be final,  binding,  and  nonappealable  with  respect to all  persons,
         including  (without  limitation)  persons who have failed or refused to
         participate in the arbitration process.

                  (d) AUTHORITY. The arbitrator(s) shall have authority to award
         relief  under  legal or  equitable  principles,  including  interim  or
         preliminary relief, and to allocate responsibility for the costs of the
         arbitration and to award recovery of attorney fees and expenses in such
         manner as is determined to be appropriate by the arbitrator(s).

                  (e) ENTRY OF JUDGMENT. Judgment upon the award rendered by the
         arbitrator(s)  may be  entered  in any  court  having in  personam  and
         subject matter jurisdiction. The Sellers and Purchaser hereby submit to
         the in personam  jurisdiction  of the  federal and state  courts in New
         Mexico  for the  purpose  of  confirming  any such  award and  entering
         judgment thereon.

                  (f) CONFIDENTIALITY.  All proceedings under this Section 9.12,
         and  all  evidence  given  or  discovered  pursuant  hereto,  shall  be
         maintained in confidence by all parties.

                  (g)   CONTINUED   PERFORMANCE.   The  fact  that  the  dispute
         resolution procedures specified in this Section 9.12 shall have been or
         may  be  invoked  shall  not  excuse  any  party  from  performing  its
         obligations  under this Agreement,  and during the pendency of any such
         procedure  all  parties  shall  continue  to perform  their  respective
         obligations  in good  faith,  subject to any rights to  terminate  this
         Agreement that may be available to any party.

         9.13  GOVERNING  LAW. This  Agreement may not be modified or terminated
orally, and shall be construed and interpreted  according to the internal law of
the state of New Mexico,  excluding  any choice of law rules that may direct the
application of the laws of another jurisdiction.

         9.14 COUNTERPARTS. This Agreement may be executed by the parties hereto
in separate counterparts,  each of which when so executed and delivered shall be
an original,  but all such  counterparts  shall together  constitute one and the
same instrument.  Each counterpart may consist of a number of copies hereof each
signed by less than all, but together signed by all, of the parties hereto.

         9.15 ENTIRE AGREEMENT. This Agreement (including the Schedules) and the
agreements,  certificates and other documents  delivered pursuant hereto contain
the entire agreement between the parties hereto. All parties collaborated in the
preparation  of this  Agreement  and it has been  reviewed by attorneys for each
party. No one party should be considered the author of any specific language for
purposes of legal presumptions.

         9.16 FURTHER ASSURANCES.  Both before and after the Closing, each party
will  cooperate  in good faith  with the  others  and will take all  appropriate
action and execute any documents,  instruments,  or conveyances of any kind that
may be  reasonable  necessary or desirable to carry out any of the  transactions
contemplated hereunder.

         9.17 SELLERS  ACTION.  Whenever in this Agreement the Sellers are given
the  discretion  to take or not to take any action,  the decision of the Sellers

                  to Closing,  and all other  operating  liabilities  (including

                  incurred in the ordinary course of business),  vendor accounts
                  payable and intercompany accounts.

                           (ii)  As  promptly  as   practicable   following  the
                  Closing,  but in no  event  later  than  45  days  thereafter,
                  Sellers and Purchaser  shall cooperate in preparing a mutually
                  agreeable statement of the Net Working Capital which shall set
                  forth the  computation  and  components  thereof in reasonable
                  detail (the "Statement of Net Working Capital").

                           (iii) On the  fifteenth  day  after the date on which
                  the  Statement of Net Working  Capital is  completed  (or such
                  earlier  date as such  statement  is  mutually  agreed upon by
                  Sellers and  Purchaser in writing),  (i) in the event that the
                  Net Working Capital exceeds $76,000,  then Purchaser shall pay
                  to Sellers pro rata an amount equal to the excess,  or (ii) in
                  the event that Net Working Capital is less than $76,000,  then
                  Sellers  shall pay to Purchaser,  pro rata,  the amount of the
                  deficiency  provided  that the  maximum  amount  of the  total
                  adjustment  payments to be made under this paragraph shall not
                  exceed $30,000.

Martinez  ("Martinez") in the amount of $19,225 (the "Loan Amount"). At Closing,
Martinez  shall be paid his portion of the  Purchase  Price less the Loan Amount

indebtedness to the Company.

         1.6 EXPENSE  REIMBURSEMENT.  Company has paid,  or has agreed to pay on
behalf  of  Sellers,  certain  legal,  accounting,  and  other  expenses  in the
aggregate amount of $6,710.32 (the "Reimbursement Amount") for which Sellers are
obligated to reimburse  Company.  At Closing,  each Seller's pro rata portion of
the  Reimbursement  Amount  (calculated  based upon each Seller's  proportionate
ownership of the Shares)  shall be deducted  from such  Seller's  portion of the
Purchase Price.

         1.7 WITHHOLDING REIMBURSEMENT. Company has paid certain compensation to
Martinez in an amount yet to be  determined  from which no tax or other  payroll
withholding deductions  ("Deductions") were made. At Closing,  Martinez shall be
paid his  portion  of the  Purchase  Price  less an amount  equal to  Deductions
(computed by ADP,  Company's  payroll agent) due with respect to $49,900 of such
compensation.  Following the Closing, HealthCare and Martinez shall negotiate in
good faith to  determine  the total  amount of  compensation  paid by Company to
Martinez on which no Deductions  were made in excess of $49,900 (the  "Excess").
If HealthCare and Martinez are unable to agree on the amount of the Excess,  the
issue  shall  be  referred  to  a  mutually   agreeable  single  arbitrator  for
resolution.  When the  amount  of the  Excess  has been  determined,  either  by
agreement  of the parties or by the  arbitrator,  Martinez  agrees to  reimburse
HealthCare  (within 15 business  days) for any  additional  Deductions  due with
respect to the Excess provided Martinez shall have no liability to HealthCare to
the extent the Excess is greater than $60,000.

                  repayment of loans made by the Sellers to the Company.

                           (x) COMPENSATION.  The Company shall not increase the
                  compensation  or benefits of any of its employees nor make any
                  other change in the terms of their employment.

                  (c) REPAYMENT OF SELLERS'  LOANS.  As of the date hereof,  the
         Company is indebted  to the  Sellers as set forth on  SCHEDULE  5.1(C).
         Notwithstanding  any other provision of this Agreement,  on or prior to
         the  Closing  date,  the  Sellers  shall  either  (i)  contribute  such
         indebtedness to the capital of the Company or (ii) cause the Company to
         repay such  indebtedness  to the extent the Company has funds available
         for such purpose.

                  (d)  REIMBURSEMENT  OF SICK AND VACATION PAY. In preparing the
         Statement  of Net  Working  Capital it has been  agreed that no accrual
         shall be made for sick and vacation pay  entitlements  for employees of
         Company. In consideration of this exclusion, Sellers agree to reimburse
         Purchaser  for any sick or vacation pay payments  Purchaser is required
         to  make to  former  employees  of  Company  who  become  employees  of
         Purchaser  and whose  employment  terminates  for any reason within the
         first six months following the Closing date to the extent such payments
         relate to accruals of sick or vacation pay prior to the Closing date.

         5.2      COVENANTS OF PURCHASER.

                  (a) RELEASE OF SELLERS' PERSONAL  GUARANTEES.  Certain Sellers
         have provided personal guarantees or have otherwise become individually
         liable  with  respect to  certain  leases,  line of credit  agreements,
         purchase  agreements with  manufacturers,  or other  agreements for the
         benefit for the Company, including, without limitation, those described
         on SCHEDULE 5.2(A). Following the Closing,  Purchaser will use its best
         efforts to obtain the  release of the  Sellers  from all such  personal
         liabilities.  To the extent that any such  release  cannot be obtained,
         Purchaser will indemnify and hold the Sellers  harmless with respect to
         any loss,  cost,  or expense  the  Sellers may incur as a result of not
         being released.

         In the  event  the  representations  and  warranties  set  forth in the

         favorable to the Sellers than the  representations  and  warranties  of
         Sellers set forth in Article III of this  Agreement,  Sellers  shall be
         entitled to the benefit of such more favorable provisions.

         8.1      INDEMNIFICATION BY THE SELLERS.

                  (a) The Sellers  hereby agree to indemnify,  defend,  and hold
         Purchaser  (and  its  directors,  officers,  shareholders,   employees,
         affiliates,  agents and assigns)  harmless  from and against all Claims
         (as defined  below)  asserted  against,  resulting to, imposed upon, or
         incurred by Purchaser  directly or indirectly by reason of, arising out
         of,  or   resulting   from  (a)  the   inaccuracy   or  breach  of  any
         representation or warranty of the Sellers contained in or made pursuant
         to this Agreement or in any of the documents delivered pursuant hereto,
         or (b) the non-performance or breach of any covenant, term or provision
         to be performed by the Sellers contained in this Agreement or in any of
         the documents delivered pursuant hereto. The indemnification obligation
         of Sellers  hereunder  is with respect to the full amount of the Claims
         (as defined  below).  As used in this  Article  VIII,  the term "Claim"
         shall include any and all losses, liabilities,  damages,  deficiencies,
         assessments,   judgments,  awards,  settlements,  costs,  and  expenses
         including without limitation penalties,  court costs, and attorney fees
         and  expenses at trial and on appeal.  Notwithstanding  the  foregoing,
         Sellers'  indemnity  obligations  shall  be  subject  to the  following
         limitations:

                           (i) Sellers  shall be  responsible  for  indemnifying
                  Purchaser  only to the extent Claims in the  aggregate  exceed
                  the sum of $2,500.

                           (ii)  Each  Seller  shall be solely  responsible  for
                  indemnification  with  respect to such  Seller's  warranty  of
                  title  regarding  Seller's  Shares and such Seller's  warranty
                  regarding the absence of liens and encumbrances  applicable to
                  such Shares;

                           (iii) Each Seller's liability with respect to a Claim
                  shall be limited to a  percentage  of such Claim equal to such
                  Seller's  percentage  ownership  of the Shares as set forth in
                  Section 1.1; and

                           (iii) Each  Seller's  maximum  liability to Purchaser
                  for  indemnification  shall not  exceed  an  amount  equal the
                  portion of the Purchase Price being paid to such Seller as set
                  forth in Section 1.3 hereof.

                  (b) Purchaser's right to  indemnification  as provided in this
         Section 8.1 shall not be eliminated,  reduced or modified in any way as
         a result  of the fact  that (i)  Purchaser  had  notice  of a breach or
         inaccuracy  of  any  representation,  warranty  or  covenant  contained
         herein,  (ii) Purchaser had been provided with access,  as requested by
         Purchaser,  to  officers  and  employees  of the  Company  and  such of
         Company's books, documents,  contracts and records as has been provided
         to Purchaser in response to Purchaser's requests.

         8.2 INDEMNIFICATION BY PURCHASER. Purchaser hereby agrees to indemnify,
defend,  and hold  harmless  the Sellers  from and  against all Claims  asserted
against,  resulting to,  imposed  upon,  or incurred by the Sellers  directly or
indirectly by reason of, arising out of, or resulting from (a) the inaccuracy or
breach of any  representation  or warranty  of  Purchaser  contained  in or made
pursuant to this Agreement or in any of the documents delivered pursuant hereto,
or (b) the  non-performance  or breach of any covenant,  term or provision to be
performed by Purchaser  contained in this  Agreement or in any of the  documents
delivered pursuant hereto. The indemnification obligation of Purchaser hereunder
is with respect to the full amount of the Claims.

         8.3  NOTICE;  DEFENSE  OF  CLAIMS.  If a claim is to be made by a party
entitled   to   indemnification   hereunder,   the   party   entitled   to  such
indemnification  shall give written notice to the indemnifying party immediately
after the party entitled to indemnification becomes aware of any fact, condition
or event  which  may give  rise to a matter  for  which  indemnification  may be
sought; provided that the failure of any indemnified party to give timely notice
shall not affect the rights to  indemnification  hereunder  except to the extent
that the indemnifying party  demonstrates  actual damage caused by such failure.
If any lawsuit or enforcement  action is filed against any party entitled to the
benefit of indemnity hereunder,  and if the indemnifying party shall acknowledge
in  writing  to the  indemnified  party  that the  indemnifying  party  shall be
obligated  under the terms of its indemnity  hereunder in  connection  with such
lawsuit,  action or claim, then the indemnifying party shall be entitled,  if it
so elects,  to take control of the defense and  investigation of such lawsuit or
action and to employ and engage attorneys of its own choice to handle and defend
the same, at the  indemnifying  party's cost, risk and expense provided that the
indemnifying  party and its counsel  shall  proceed with  diligence  and in good
faith with  respect  thereto.  The  indemnified  party  shall  cooperate  in all
reasonable  respects  with the  indemnifying  party  and such  attorneys  in the
investigation,  trial and  defense  of such  lawsuit  or action  and any  appeal
arising therefrom; provided, however, that the indemnified party may, at its own
cost,  participate  in the  investigation,  trial and defense of such lawsuit or
action and any appeal arising therefrom.

         8.4 SURVIVAL OF  REPRESENTATIONS.  All  representations  and warranties
made by the  parties  in this  Agreement  are  made  only as of the date of this
Agreement but will survive the consummation of the transactions  contemplated by
this  Agreement  for a period  ending 90 days after the second  fiscal  year end
(July  31)  of  Purchaser  which  occurs  after  the  Closing  (except  for  the
representations  and  warranties of the Sellers set forth in Section 3.11 hereof
which shall expire 90 days after the  applicable  statutes of  limitation  shall
have run with  respect to all tax  returns  filed by the Company for all periods
ended on or before the Closing) after which all such

Section 9.2 must be by an  instrument  in writing  signed on behalf of the party
granting the extension or waiver.  A waiver by any party of any provision hereof

         9.11     RESOLUTION OF DISPUTES.

                  (a) ARBITRATION. Any dispute, controversy or claim arising out
         of or relating to this  Agreement or the  performance by the parties of
         its terms shall be settled by binding  arbitration held in Los Angeles,
         California,  in accordance with the Commercial Arbitration Rules of the
         American Arbitration Association then in effect, except as specifically
         otherwise provided in this Section 9.11. Notwithstanding the foregoing,
         HealthCare,   in  its  discretion,   apply  to  a  court  of  competent
         jurisdiction  for  equitable  relief from any  violation or  threatened
         violation of the covenants of the Shareholders  under Section 5.1(b) of
         this Agreement.

                  (b)  ARBITRATORS.  If the matter in controversy  (exclusive of
         attorney fees and expenses) shall appear,  as at the time of the demand
         for  arbitration,  to exceed  $50,000,  then the panel to be  appointed
         shall  consist of three  neutral  arbitrators;  otherwise,  one neutral
         arbitrator.

                  (c) PROCEDURES;  NO APPEAL. The arbitrator(s) shall allow such
         discovery  as  the  arbitrator(s)   determine   appropriate  under  the
         circumstances  and  shall  resolve  the  dispute  as  expeditiously  as
         practicable,  and if reasonably practicable,  within 120 days after the
         selection  of the  arbitrator(s).  The  arbitrator(s)  shall  give  the
         parties written notice of the decision,  with the reasons  therefor set
         out,  and shall have  thirty (30) days  thereafter  to  reconsider  and
         modify  such  decision  if any party so  requests  within ten (10) days
         after the decision. Thereafter, the decision of the arbitrator(s) shall
         be final,  binding,  and  nonappealable  with  respect to all  persons,
         including  (without  limitation)  persons who have failed or refused to
         participate in the arbitration process.

                  (d) AUTHORITY. The arbitrator(s) shall have authority to award
         relief  under  legal or  equitable  principles,  including  interim  or
         preliminary relief, and to allocate responsibility for the costs of the
         arbitration and to award recovery of attorney fees and expenses in such
         manner as is determined to be appropriate by the arbitrator(s).

                  (e) ENTRY OF JUDGMENT. Judgment upon the award rendered by the
         arbitrator(s)  may be  entered  in any  court  having in  personam  and
         subject matter  jurisdiction.  The Shareholders  and HealthCare  hereby
         submit to the in personam  jurisdiction of the federal and state courts
         in California for the purpose of confirming any such award and entering
         judgment thereon.

                  (f) CONFIDENTIALITY.  All proceedings under this Section 9.11,
         and  all  evidence  given  or  discovered  pursuant  hereto,  shall  be
         maintained in confidence by all parties.

                  (g)   CONTINUED   PERFORMANCE.   The  fact  that  the  dispute
         resolution  procedures  specified in this Section 13 shall have been or
         may  be  invoked  shall  not  excuse  any  party  from  performing  its
         obligations  under this Agreement,  and during the pendency of any such
         procedure  all  parties  shall  continue  to perform  their  respective
         obligations in good

in separate counterparts,  each of which when so executed and delivered shall be

                                SUBORDINATED NOTE

                                                              December ___, 1996

      1.  HealthCare  Hearing  Clinics,  Inc., a corporation  duly organized and
existing under the laws of the State of Washington  ("HHC"),  for value received
hereby  promises  to pay to  the  order  of  __________________  ("Holder")  the
principal sum of $___________ for the amount of the note payable as follows:

             (a)  Interest  on the  unpaid  balance  hereof  at the  rate of 6.5
                  percent  per annum  shall be payable  on a calendar  quarterly
                  basis on or before  the tenth  day  following  the end of each
                  quarter, and

             (b)  The  principal  amount  hereof shall be payable in three equal
                  installments due on the first three  anniversaries of the date
                  hereof.

This note has been  delivered  pursuant  to Section  1.4 of that  certain  Stock
Purchase and Sale Agreement dated December 13, 1996, to which HHC and the Holder
hereof are  parties  (the  "Agreement").  The amount owed  Holder  hereunder  is
expressly  subject  to  setoff  as  provided  in  Sections  1.5  and  1.6 of the
Agreement.

      2. HHC, for itself and its successors  and assigns,  covenants and agrees,
and by acceptance hereof Holder likewise covenants and agrees,  that the payment
of the principal of this note is hereby  expressly  subordinated,  to the extent
and in the  manner  hereinafter  set  forth,  in right of  payment  to the prior
payment in full of all Senior Indebtedness. As used herein "Senior Indebtedness"
means the principal of (and premium, if any) and unpaid interest on indebtedness
for borrowed  money of HHC  (including  guarantees  by HHC of  indebtedness  for
borrowed money of others),  whether  outstanding on the date hereof or hereafter
created, incurred, assumed, or guaranteed.

      3. Upon any  distribution of assets by HHC upon any  dissolution,  winding
up,  liquidation,  or reorganization of HHC, whether in bankruptcy,  insolvency,
reorganization,  or  receivership  proceedings  or  upon an  assignment  for the
benefit of creditors or any other  marshalling of the assets and  liabilities of
HHC or any other winding up of HHC (subject to the power of a court of competent
jurisdiction to make other equitable  provision  reflecting the rights conferred
hereby upon the Senior Indebtedness and the holders thereof with respect to this
note and Holder by a lawful plan of reorganization  under applicable  bankruptcy
law):

             (a)  the holders of all Senior Indebtedness shall first be entitled
                  to  receive  payment  in full of the  principal  thereof  (and
                  premium, if any) and the



                                                     - 1 -

                  interest due thereon  before Holder is entitled to receive any
                  payment upon the indebtedness evidenced by this note;

             (b)  any  payment or  distribution  of assets of HHC of any kind or
                  character,  whether in cash, property, or securities, to which
                  Holder  would be entitled  except for the  provisions  of this
                  Section 3 shall be paid by the liquidating trustee or agent or
                  other person  making such payment or  distribution,  whether a
                  trustee in bankruptcy,  a receiver or  liquidating  trustee or
                  otherwise,  directly to the holders of Senior  Indebtedness or
                  their  representative or  representatives or to the trustee or
                  trustees  under any  indenture  under  which  any  instruments
                  evidencing  any of such  Senior  Indebtedness  may  have  been
                  issued, ratably accordingly to the aggregate amounts remaining
                  unpaid on account of the  principal of (and  premium,  if any)
                  and interest on the Senior Indebtedness held or represented by
                  each,  to the extent  necessary to make payment in full of all
                  Senior Indebtedness  remaining unpaid,  after giving effect to
                  any concurrent  payment or distribution to the holders of such
                  Senior Indebtedness; and

             (c)  in the event that,  notwithstanding the foregoing, any payment
                  or  distribution  of assets  of HHC of any kind or  character,
                  whether in cash, property, or securities, shall be received by
                  Holder before all Senior  Indebtedness  is paid in full,  such
                  payment or  distribution  shall be paid over to the holders of
                  such   Senior   Indebtedness   or  their   representative   or
                  representatives  or to  the  trustee  or  trustees  under  any
                  indenture under which any  instruments  evidencing any of such
                  Senior   Indebtedness   may  have  been  issued,   ratably  as
                  aforesaid,  for  application  to the  payment  of  all  Senior
                  Indebtedness   remaining   unpaid   until   all  such   Senior
                  Indebtedness shall have been paid in full, after giving effect
                  to any concurrent  payment or  distribution  to the holders of
                  such Senior  Indebtedness;  provided,  however,  that any such
                  payment or distribution  --------  -------  received by Holder
                  shall  not be  required  to be paid  over to a holder  of such
                  Senior Indebtedness as aforesaid if upon notice from Holder to
                  such holder of Senior  Indebtedness,  which notice shall state
                  that such payment or distribution  has been received by Holder
                  and request that such holder notify Holder of the amounts then
                  due and owing to such holder on such Senior Indebtedness, such
                  holder of such  Senior  Indebtedness  shall  fail to so notify
                  Holder of such amounts then due and owing.  The  provisions of
                  this   paragraph  (c)  shall  not  apply  to  any  payment  or
                  distribution of assets received by Holder prior to the date of
                  any distribution, assignment, marshalling, or other winding up
                  referred to in the first sentence of this Section 3.

Subject  to the  payment  in full of all Senior  Indebtedness,  Holder  shall be
subrogated  to the  rights of the  holders  of Senior  Indebtedness  to  receive
payments or distributions of cash,  property,  or securities of HHC, as the case
may be, applicable to the Senior  Indebtedness  until the principal of this note
shall be paid in full and no such payments or  distributions  to Holder of cash,
property,  or  securities  otherwise  distributable  to the Senior  Indebtedness
shall,  as  between  HHC,  its  creditors,  other  than the  holders  of  Senior
Indebtedness,  and Holder,  be deemed to be a payment by HHC to or on account of
this note. It is understood  that the  provisions of Sections 2 and 3 are solely
for the purpose of defining the relative rights of Holder,  on the one hand, and
the holders of the Senior  Indebtedness on the other hand, against HHC and their
properties.  Nothing  contained in Sections 2 and 3 or elsewhere in this note is
intended to or shall impair,  as between HHC and Holder,  the obligation of HHC,
which is unconditional and absolute, to pay to Holder the principal of this note
as and when the same shall become due and payable in  accordance  with its terms
or to affect the relative  rights of Holder and  creditors of HHC other than the
holders  of  Senior  Indebtedness,  nor  shall  anything  herein or in this note
prevent Holder from  exercising all remedies  otherwise  permitted by applicable
law upon default,  subject to the rights,  if any, under Sections 2 and 3 of the
holders of Senior  Indebtedness in respect to cash,  property,  or securities of
HHC received upon the exercise of any such remedy.

      4. In the event and during the continuation of any default of which Holder
shall have received  written  notice in the payment of principal of (or premium,
if any) or interest on any Senior  Indebtedness  beyond any applicable period of
grace,  or in the event  that any event of  default  with  respect to any Senior
Indebtedness  of which  Holder  shall have  received  written  notice shall have
occurred and be continuing,  or would occur as a result of the payment  referred
to hereinafter, permitting the holders of such Senior Indebtedness (or a trustee
or other  representative  on behalf of the holders  thereof) to  accelerate  the
maturity thereof,  then, unless and until such default or event of default shall
have been cured or waived or shall have ceased to exist, no payment of principal
of this note shall be made by HHC;  provided,  however that such  prohibition on
the payment of  principal  of this note shall not apply if all holders of Senior
Indebtedness,  upon receiving  written notice from HHC requesting  permission to
make a payment of principal on this note,  fail to notify HHC in writing  within
30 days after the date the notice  requesting  such  permission is received that
such permission is denied.

      5. Nothing  contained in Sections 2, 3, or 4 shall prevent HHC at any time
except during the pendency of any of the conditions  described in Sections 3 and
4, from making the scheduled principal payment provided for in Section 1.

      6. No recourse shall be had for the payment of the principal on this note,
or for any claim based  hereon,  or  otherwise  in respect  hereof,  against any
incorporator,  stockholder,  officer,  or director,  as such, past,  present, or
future,  of  HHC or of any  successor  corporation,  whether  by  virtue  of any
constitution, statute, or rule of law,



                                                     - 3 -

or by the  enforcement  of any  assessment  or  penalty or  otherwise,  all such
liability being, by the acceptance  hereof and as part of the  consideration for
the issue hereof, expressly waived and released.

      7.  The  occurrence  of any  one or  more of the  following  events  shall
constitute an Event of Default under this note:

             (a)  HHC shall  fail to observe or  perform  any  obligation  to be
                  observed or performed  by it under this note,  under the Stock
                  Purchase and Sale  Agreement  dated as of December ___,  1996,
                  between HHC and Holder,  within thirty (30) days after written
                  notice from Holder to perform or observe the  obligation or to
                  substantially  commence to observe or perform  and  thereafter
                  diligently  complete  observance  or  performance  if complete
                  observance or  performance  of the  obligation is not possible
                  within thirty (30) days;

             (b)  HHC shall be in default  under or fail to make any  payment of
                  principal  of or interest  on any  indebtedness  for  borrowed
                  money in a principal amount of at least Fifty Thousand Dollars
                  ($50,000)  and such default or failure shall  continue  beyond
                  any applicable grace period;

             (c)  HHC shall admit its  inability to pay its debts as they mature

under the Plan are Shares of Common Stock,  which may be either  authorized  and
unissued Shares or reacquired  Shares.  No fractional Shares may be issued under

Subsidiaries  (who may also be directors of Corporation or a Subsidiary) who are
full-time  employees  and  who,  in  the  Board's  judgment,   are  or  will  be
contributors  to the  long-term  success of  Corporation  shall be  eligible  to
receive Awards under the Plan.

                                    ARTICLE 6
                                     AWARDS

                  6.1 TYPES OF AWARDS.  The types of Awards  that may be granted
under the Plan are Options governed by Article of the Plan.

                  6.2 GENERAL. Subject to the limitations of the Plan, the Board
may cause  Corporation to grant Awards to such  Participants,  at such times, of
such types,  in such amounts,  for such periods,  with such option  prices,  and
subject to such terms, conditions,  limitations,  and restrictions as the Board,
in its  discretion,  deems  appropriate.  Awards may be  granted  as  additional
compensation  to a  Participant  or  in  lieu  of  other  compensation  to  such
Participant.  A  Participant  may receive  more than one Award and more than one
type of Award under the Plan.

                  6.3  NONUNIFORM  DETERMINATIONS.  The  Board's  determinations

limitation,  the selection of Participants to receive  Awards,  the type,  form,
amount,  and timing of  Awards,  the terms of  specific  Award  Agreements,  and
elections  and  determinations  made by the Board with  respect to  exercise  or
payments of Awards, need not be uniform and may be made by the


                                                     - 5 -

Board selectively among Participants and Awards, whether or not Participants are
similarly situated.

                  6.4  AWARD  AGREEMENTS.  Each  Award  will be  evidenced  by a
written  Award  Agreement  between   Corporation  and  the  Participant.   Award
Agreements  must be  approved  by, or at the  discretion  of, the Board and may,
subject to the  provisions of the Plan,  contain any  provision  approved by the
Board.

                  6.5  PROVISIONS  GOVERNING  ALL  AWARDS.  All  Awards  will be
subject to the following provisions:

                  (a)  RIGHTS  AS  SHAREHOLDERS.  No  Participant  will have any
         rights of a  shareholder  with  respect  to Shares  subject to an Award
         until such Shares are issued in the name of the Participant.

                  (b)  EMPLOYMENT  RIGHTS.  Neither the adoption of the Plan nor
         the  granting  of any  Award  will  confer on any  person  the right to
         continued  employment  with  Corporation or any Subsidiary and will not
         interfere in any way with the right of  Corporation  or a Subsidiary to
         terminate such person's employment at any time for any reason or for no
         reason, with or without cause.

                  (c) TERMINATION OF EMPLOYMENT.  The terms and conditions under
         which an  Award  may be  exercised,  if at all,  after a  Participant's
         termination of employment will be determined by the Board and specified
         in the applicable Award Agreement.

                  (d) CHANGE IN  CONTROL.  The  Board,  in its  discretion,  may
         provide in any Award Agreement that in the event of a change in control
         of  Corporation  (as the  Board  may  define  such  term  in the  Award
         Agreement), as of the date of such change in control:

                           (i) All, or a specified  portion of, Awards requiring
                  exercise  will  become  fully  and  immediately   exercisable,
                  notwithstanding any other limitations on exercise;

                           (ii) All, or a specified  portion of, Awards  subject
                  to Restrictions will become fully Vested; and

                           (iii) All, or a specified  portion of, Awards subject
                  to Performance Goals will be deemed to have been fully earned.

         The Board, in its discretion,  may include change in control provisions
         in some Award  Agreements  and not in  others,  may  include  different
         change in control  provisions in different  Award  Agreements,  and may
         include   change  in  control   provisions  for  some  Awards  or  some
         Participants and not for others.

                  (e) REPORTING  PERSONS.  With respect to all Awards granted to
         Reporting Persons, the Award Agreement will provide that:

                           (i) Awards requiring exercise will not be exercisable
                  until at least  six  months  after  the  date  the  Award  was
                  granted,  except in the case of the death or Disability of the
                  Participant; and

                           (ii)  Shares  issued  pursuant to any other Award may
                  not be sold by the  Participant  for at least six months after
                  acquisition,  except in the case of the death or Disability of
                  the Participant;

         provided,  however, that (unless an Award Agreement provides otherwise)
         the  limitation of this Section (e) will apply only if or to the extent
         required  by  Rule  16b-3  under  the  Exchange  Act or any  applicable
         successor  provision.  Award Agreements for Awards to Reporting Persons
         will also  comply  with any  future  restrictions  imposed by such Rule
         16b-3.

                  (f) SERVICE PERIODS. At the time of granting Awards, the Board
         may specify,  by  resolution or in the Award  Agreement,  the period or
         periods of service  performed or to be performed by the  Participant in
         connection with the grant of the Award.

                                    ARTICLE 7
                                     OPTIONS

                  7.1 TYPES OF OPTIONS. Options granted under the Plan may be in
the form of Incentive Stock Options or Nonqualified  Options.  The grant of each
Option and the Award Agreement governing each Option will identify the Option as
an ISO or an NQO.  In the event the Code is amended to provide  for  tax-favored
forms of stock options other than or in addition to Incentive Stock Options, the
Board may grant Options under the Plan meeting the requirements of such forms of
options.

                  7.2  GENERAL.  Options  will  be  subject  to  the  terms  and
conditions  set forth in Article of the Plan and this  Article  and may  contain
such  additional  terms  and  conditions,  not  inconsistent  with  the  express
provisions of the Plan, as the Board deems desirable.

                  7.3 OPTION PRICE.  Each Award Agreement for Options will state
the  option  exercise  price  per Share of Common  Stock  purchasable  under the
Option,  which will not be less than 100 percent of the Fair  Market  Value of a
Share on the date of grant.

                  7.4 OPTION  TERM.  The Award  Agreement  for each  Option will
specify the term of each Option not to exceed five years during which the Option
may be exercised, as determined by the Board.

                  7.5 TIME OF EXERCISE. The Award Agreement for each Option will
specify, as determined by the Board:



                                                     - 7 -

<PAGE>



                  (a) The time or times when the Option will become  exercisable
         and whether the Option will become  exercisable in full or in graduated
         amounts over a period specified in the Award Agreement;

                  (b) Such other terms, conditions,  and restrictions as to when
         the Option may be exercised as are determined by the Board; and

                  (c) The  extent,  if any,  to which  the  Option  will  remain
         exercisable  after  the  Participant   ceases  to  be  an  employee  of
         Corporation or a Subsidiary.

An Award  Agreement for an Option may, in the  discretion of the Board,  provide
whether,  and to what  extent,  the Option  will  become  immediately  and fully
exercisable  (i) in the event of the death,  Disability,  or  Retirement  of the
Participant, or (ii) upon the occurrence of a change in control of Corporation.

                  7.6 METHOD OF EXERCISE.  The Award  Agreement  for each Option
will  specify the method or methods of payment  acceptable  upon  exercise of an
Option.  An Award Agreement may provide that the option price is payable in full
in cash or, at the discretion of the Board,  in  installments  on such terms and
over such period as the Board  determines  or in any other form  approved by the
Board.

                  7.7 SPECIAL RULES FOR INCENTIVE STOCK OPTIONS.  In the case of
an Option  designated as an Incentive Stock Option,  the terms of the Option and
the Award  Agreement  will be in  conformance  with the statutory and regulatory
requirements specified in Section 422 of the Code, as in effect on the date such
ISO is granted.  ISOs may not be granted under the Plan after December 10, 2006,
unless the ten-year  limitation  of Section  422(b)(2) of the Code is removed or
extended.

                                    ARTICLE 8
                ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, ETC.

                  8.1 PLAN DOES NOT RESTRICT  CORPORATION.  The existence of the
Plan and the Awards  granted  under the Plan will not affect or  restrict in any
way the right or power of the Board or the  shareholders  of Corporation to make
or authorize any adjustment,  recapitalization,  reorganization, or other change
in Corporation's capital structure or its business,  any merger or consolidation
of  the  Corporation,  any  issue  of  bonds,  debentures,  preferred  or  prior
preference  stocks  ahead of or  affecting  Corporation's  capital  stock or the
rights  thereof,  the  dissolution  or liquidation of Corporation or any sale or
transfer of all or any part of its assets or  business,  or any other  corporate
act or proceeding.

                  8.2  ADJUSTMENTS  BY THE BOARD.  In the event of any change in
capitalization  affecting  the  Common  Stock  of  Corporation,  such as a stock
dividend,  stock  split,  recapitalization,   merger,  consolidation,  split-up,
combination or exchange of shares or other form of reorganization,  or any other
change affecting the Common Stock, such  proportionate  adjustments,  if any, as
the Board, in its sole discretion,  may deem appropriate to reflect such change,
will be made with respect to the aggregate number of Shares for which Awards in


                                                     - 8 -

<PAGE>



respect  thereof may be granted  under the Plan,  the  maximum  number of Shares
which may be sold or awarded to any Participant, the number of Shares covered by
each  outstanding  Award,  and the  price per Share in  respect  of  outstanding
Awards. The Board may also make such adjustments in the number of Shares covered
by,  and  price  or other  value of any  outstanding  Awards  in the  event of a
spin-off  or  other  distribution   (other  than  normal  cash  dividends),   of
Corporation assets to shareholders.

                                    ARTICLE 9
                            AMENDMENT AND TERMINATION

                  Without further  approval of Corporation's  shareholders,  the
Board may at any time  terminate  the Plan, or may amend it from time to time in
such  respects as the Board may deem  advisable,  except that the Board may not,
without approval of the  shareholders,  make any amendment that would materially
increase the aggregate number of shares of Common Stock that may be issued under
the Plan  (except for  adjustments  pursuant to Article 8 of the Plan).  Without
further shareholder approval,  the Board may amend the Plan to take into account
changes in applicable securities,  federal income tax laws, and other applicable
laws. Further,  should the provisions of Rule 16b-3, or any successor rule under
the Exchange Act be amended,  the Board,  without further shareholder  approval,
may amend the Plan as necessary to comply with any modifications to such rule.

                                   ARTICLE 10
                                  MISCELLANEOUS

                  10.1  TAX WITHHOLDING.

                  10.1.1 GENERAL. Corporation will have the right to deduct from
any  settlement  of any Award under the Plan,  including the delivery of Shares,
any federal,  state,  or local taxes of any kind  required by law to be withheld
with  respect to such  payments or to take such other action as may be necessary
in the opinion of Corporation to satisfy all obligations for the payment of such
taxes.  The  recipient  of any  payment  or  distribution  under the Plan may be
required to make  arrangements  satisfactory to Corporation for the satisfaction
of any such  withholding  tax  obligations,  whether or not such recipient is an
employee  of  Corporation  or a  Subsidiary  on the  date  of  such  settlement.
Corporation will not be required to make any such payment or distribution  under
the Plan until such obligations are satisfied.

                  10.2 UNFUNDED PLAN. The Plan will be unfunded and  Corporation
will not be required to segregate any assets that may at any time be represented
by Awards  under the Plan.  Any  liability  of  Corporation  to any person  with
respect to any Award under the Plan will be based  solely  upon any  contractual
obligations  that may be effected  pursuant to the Plan.  No such  obligation of
Corporation will be deemed to be secured by any pledge of, or other  encumbrance
on, any property of Corporation.

                  10.3 PAYMENTS TO TRUST. The Board is authorized to cause to be
established a trust agreement or several trust  agreements  whereunder the Board
may make payments of


                                                     - 9 -

<PAGE>



amounts due or to become due to Participants in the Plan. However, the Board has
no obligation to establish such a trust or fund.

                  10.4 ANNULMENT OF AWARDS. Any Award Agreement may provide that
the  grant of an Award  payable  in cash is  provisional  until  cash is paid in
settlement  of such  Award or that the  grant of an Award  payable  in Shares is
provisional  until the Participant  becomes entitled to the stock certificate in
settlement  of such  Award.  In the event the  employment  of a  Participant  is
terminated for cause (as defined below),  any Award that is provisional  will be
annulled as of the date of such  termination for cause.  For the purpose of this
Section  10.4,  the term  "for  cause"  will have the  meaning  set forth in the
Participant's employment agreement, if any, or otherwise means any discharge for
material or flagrant  violation of the policies and procedures of Corporation or
for other job performance or conduct that is materially  detrimental to the best
interests of Corporation, as determined by the Board.

                  10.5  ENGAGING  IN  COMPETITION  WITH  CORPORATION.  Any Award
Agreement  may  provide  that,  if  a  Participant  terminates  employment  with
Corporation  or a  Subsidiary  for any reason  whatsoever,  and within 18 months
after the date of such termination accepts employment with any competitor of (or
otherwise  engages in  competition  with)  Corporation,  the Board,  in its sole
discretion,  may require such  Participant to return to Corporation the economic
value  of any  Award  that is  realized  or  obtained  (measured  at the date of
exercise, Vesting, or payment) by such Participant at any time during the period
beginning on the date that is six months prior to the date of such Participant's
termination of employment with Corporation.

                  10.6 OTHER  CORPORATION  BENEFIT  AND  COMPENSATION  PROGRAMS.
Payments  and other  benefits  received  by a  Participant  under an Award  made
pursuant  to the Plan  will not be  deemed  a part of a  Participant's  regular,
recurring  compensation  for purposes of the termination  indemnity or severance
pay law of any state or country and will not be included  in, or have any effect
on, the  determination  of benefits  under any other  employee  benefit  plan or
similar arrangement  provided by Corporation or a Subsidiary unless expressly so
provided by such other plan or arrangements, or except where the Board expressly
determines that an Award or portion of an Award should be included to accurately
reflect  competitive  compensation  practices or to recognize  that an Award has
been made in lieu of a portion of cash  compensation.  Awards under the Plan may
be made in combination  with or in tandem with, or as  alternatives  to, grants,
awards,   or  payments  under  any  other   Corporation  or  Subsidiary   plans,
arrangements,  or  programs.  The  Plan  notwithstanding,   Corporation  or  any
Subsidiary   may  adopt  such  other   compensation   programs  and   additional
compensation  arrangements as it deems necessary to attract,  retain, and reward
employees and directors for their service with Corporation and its Subsidiaries.

will be in  compliance  with  applicable  federal  and  state  securities  laws.
Certificates  for  Shares  delivered  under  the  Plan  may be  subject  to such
stop-transfer  orders and other  restrictions as the Board deems advisable under
the rules, regulations, and other requirements of the Securities and Exchange

Code or federal  securities laws, the Plan and all actions taken thereunder will
be governed by and construed in accordance with the laws of Oregon.

                              EMPLOYMENT AGREEMENT
                                (Vice President)


                  AGREEMENT  dated  October 1, 1996,  by and between  HEALTHCARE
HEARING CLINICS, INC., a Washington corporation  ("HealthCare"),  and GREGORY J.
FRAZER ("Employee").

                                    RECITALS:

                  A.  HealthCare  operates  audiology and hearing aid clinics in
the United States which provide  services  directly to members of the public and
through referrals from the medical community.

                  B.  Employee  is  a  principal  shareholder  in  a  number  of
California  corporations  operated in conjunction with each other under the name
"Hearing Care Associates".  Such corporations  operate audiology and hearing aid
clinics in the Los Angeles, California,  metropolitan area. Pursuant to a Merger
Agreement  dated  October  1,  1996  (the  "Merger  Agreement"),  three  of such
corporations Hearing Care Associates - Glendale, Inc., Hearing Care Associates -
Glendora,   Inc.,  and  Hearing  Care   Associates  -  Northridge,   Inc.  (such
corporations  are  hereinafter  referred  to as "HCA"),  are being  acquired  by
HealthCare by means of a merger of HCA into HealthCare.

                  C.  Employee has heretofore been an officer of HCA and
as a result possesses an intimate knowledge of the business
operations, policies, methods, and personnel of HCA.

                  D.  Because  of,  among  other  matters,  Employee's  intimate
knowledge  of HCA and his  reputation  and  relationships  with,  among  others,
clients, customers,  suppliers,  distributors,  and employees of HCA, HealthCare
recognizes  and Employee  acknowledges  the  detrimental  effect on the business
HealthCare is acquiring from HCA and the decreased  value of such business which
would result if Employee were to enter into competition with HealthCare.

                  E. It is a material  condition to  HealthCare's  obligation to
consummate the  transaction  provided for in the Merger  Agreement and the other
transactions contemplated thereby that Employee enter into this Agreement.

                                                      TERMS:

                  In  consideration  of the  premises  and the mutual  covenants
herein contained, the parties agree as follows:



                                                     - 1 -

         1.       EMPLOYMENT RELATIONSHIP.

                  1.1 EMPLOYMENT.  On the terms and conditions set forth herein,
HealthCare  hereby employs  Employee and Employee hereby accepts such employment
with HealthCare as Vice  President-Business  Development.  The Employee shall be
responsible for developing  relationships  with existing  managed care and group
benefit plans,  and initiating and  implementing  managed care and group benefit
plans, for and on behalf of the entire HealthCare  operation.  During the period
of  employment,   the  Employee  shall  perform  such  additional  services  not
inconsistent  with his position as shall be  designated  by the President or the
Board of Directors of HealthCare,  use his best efforts to promote the interests
of  HealthCare,  and  serve as a  director  of  HealthCare.  During  the term of
employment neither Employee's title nor responsibilities shall be diminished and
he  shall  continue  to enjoy  all the  benefits,  responsibilities,  authority,
perquisites and participation in the management and affairs of HealthCare as may
be afforded comparable senior executive employees of HealthCare.  For so long as
Employee  serves as a director of HealthCare,  HealthCare  shall fully indemnify
Employee  for the  performance  of his duties as a director  and shall  maintain
directors  and  officers  liability  insurance  in such  amounts  and with  such
carriers as are reasonable in HealthCare's  industry. The failure of Employee to
be elected at any time as a director or the  cessation  of his  services as such
through no fault of his own shall not  affect  nor  reduce  any of  HealthCare's
obligations  hereunder  and shall not be  considered a breach  hereof.  Employee
shall not be required  to perform  services  at or  relocate  his  practice to a
clinic other than the HCA clinic at which he  currently or at any time  performs
services  hereunder  without his prior consent.  Employee  understands  that the
performance of his duties hereunder may require  reasonable travel, but Employee
shall in no event be required  to travel on  weekends  or  holidays  without his
consent.

                  1.2 EXCLUSIVE  EMPLOYMENT.  During the term of this Agreement,
Employee will devote his full working time, energy,  attention, and skill to his
duties hereunder and to the promotion of HealthCare's business.  During the term
of this Agreement,  Employee shall not engage in any other business activity for
gain provided that this restriction  shall not be construed to prohibit Employee
from making personal investments in such form and manner as will neither require
any  material  amount of time or  services  or violate  any of the terms of this
Agreement.

         2.       TERM.

                  This Agreement is being entered into in  contemplation  of the
acquisition  by  HealthCare  of the  interests  in HCA owned by  Employee.  This
Agreement  shall  become  effective  as of the  date of  closing  of the  merger
provided for in the Merger Agreement (the "Closing  Date").  The initial term of
this Agreement shall commence as of the Closing Date and shall end on the fifth


                                                     - 2 -

anniversary of such date. unless sooner terminated pursuant to the terms hereof.
Provided this Agreement has not been earlier terminated,  upon the expiration of
the  initial  term  hereof,  it shall be renewed  and  continue  for  successive
additional 12-month periods until terminated.  Either party hereto may terminate
this  Agreement as of the end of the initial term or any renewal term by written
notice to the other party given at least 90 days prior to the end of the initial
or a renewal term.

         3.       COMPENSATION.

                  3.1 SALARY.  For his services under this  Agreement,  Employee
shall receive a base salary of $110,000 per year which shall be paid (subject to
applicable  payroll  withholding  deductions)  in accordance  with  HealthCare's
payroll  policy as in effect from time to time.  For any partial  month  worked,
such salary shall be pro rated on a daily basis. If Employee's  salary and other
remuneration  is  increased  at any time during the term of this  Agreement,  it
shall not  thereafter  be  decreased or  diminished  below the level of the most
recent increase.

                  3.2  BONUSES.  For each of the  first  three  fiscal  years of
HealthCare which end after the date hereof, Employee shall be paid a bonus equal
to 9.04 percent of the  aggregate  net income of the clinics HCA is operating at
the date  hereof in excess of a total of  $486,390  ("Base Net  Income").  It is
presently  contemplated  that  HealthCare  will acquire  Employee's  interest in
additional  corporations  operating under the name Hearing Care  Associates.  As
such additional corporations are acquired, Base Net Income shall be increased to
reflect such  acquisitions  in  accordance  with  SCHEDULE 3.2 attached  hereto.
Clinic net income shall be  calculated  in accordance  with  generally  accepted
accounting  principles  applied on a consistent  basis. In calculating  such net
income, clinics shall be subject to a corporate overhead expense charge equal to
6 percent of gross  revenues.  Calculation of Employee's  bonus shall be made in
accordance with the following example:

                  Revenue                                  $ 4,000,000

                                                           ===========

Bonus  payments  shall be made within 90 days  following  the end of each fiscal
year. In the event this Agreement and Employee's employment hereunder terminates
prior to the end of a fiscal  year,  Employee's  bonus  for such  year  shall be
computed based upon net income calculated through the date of termination.

         the details of which are not generally known;

                  (c)  Marketing  information  including,  but  not  limited  to

                  Employee   agrees   to  keep   all   Proprietary   Information
confidential.  Except as may be  necessary in the  performance  of his duties on
behalf of HealthCare,  Employee will make no use of and will not  communicate or

at any time after his employment with HealthCare  terminates use any Proprietary
Information for his own benefit or on behalf of any person,  firm,  partnership,

apply to any  information  that by means  other than  Employee's  deliberate  or
inadvertent  disclosure  becomes  well  known  to the  public  or to  disclosure
compelled by judicial or administrative  proceedings  after Employee  diligently
(at HealthCare's  expense) tries to avoid each disclosure and affords HealthCare
the  opportunity to obtain  assurance that  compelled  disclosures  will receive
confidential treatment.

HealthCare's  business  operations,  copy or duplicate any of the aforementioned
documents or objects,  nor remove them from HealthCare's  facilities nor use any
information  concerning them except for HealthCare's benefit,  either during his
employment  or  thereafter.  Employee  agrees  that he will  deliver  all of the
aforementioned documents and objects that may be in his possession to HealthCare
on termination of his employment,  or at any other time on HealthCare's request,
together with his written  certification  of compliance  with the  provisions of
this Section 4.2.

                  4.3 NONSOLICITATION  AND NONCOMPETITION.  Employee agrees that

         HealthCare  while  Employee was employed  hereunder  (such period being
         hereinafter referred to as the "Employment Period"); or

                  (d) Disturb, hire, entice away or in any other manner persuade
         any employee,  client,  or customer of HealthCare  who was an employee,
         client,  or customer of HealthCare  during the  Employment  Period,  to
         alter,   modify  or  terminate  his,  her,  or  its  relationship  with
         HealthCare as an employee, client, or customer as the case may be.

Notwithstanding  the foregoing,  Employee may be a passive  investor in up to 10
percent of the stock of any publicly traded company.

                  4.4      REMEDIES FOR BREACH.  Employee acknowledges that
in the event of his breach of this Section 4, damages will be
difficult or impossible to ascertain, and it is therefore agreed
that HealthCare, in addition to, and without limiting any other


                                                     - 7 -

remedy or right it may have,  shall  have the right to an  injunction  enjoining
said  breach  issued  by a court of  competent  jurisdiction.  In the  event any
litigation  or  controversy  between  the  parties  hereto  arises  out of or in
connection  with this  Agreement,  the  prevailing  party in such  litigation or
controversy  shall be  entitled to recover  from the other party all  reasonable
attorney fees, expenses and costs, including those associated with any appellate
proceedings or post-judgment collection proceedings.

         5.       DEVELOPMENTS.

                  There shall become the exclusive  property of HealthCare every
invention and  improvement  conceived,  invented or developed by Employee during
the term hereof and for a period of one year thereafter relating to or usable in
(i) in any business then being carried on or actively contemplated by HealthCare
or (ii) the production of any product then being manufactured,  sold, used or in
the  process  of  development  by  HealthCare  or  which  may be sold or used in
competition  with any such  product.  With respect to all such  inventive  ideas
originated  or  developed  by  Employee  while in the employ of  HealthCare,  or
developed by Employee within the period of one year thereafter,  which relate to
the business or related products,  designs, ideas or techniques sold, used or in
the  process  of  development  by  HealthCare  during  the term,  or as to which
Employee  has  acquired  information  as a result  of such  employment,  and all
patents, trademarks and/or copyrights obtained on such inventive ideas:

                  (a) Employee agrees to disclose and assign, without charge but
         at  HealthCare's  cost,  all  such  inventive  ideas  and any  patents,
         trademarks and/or copyrights obtained thereon to HealthCare;

                  (b)  Employee  agrees  that all such  inventive  ideas and any
         patents,  trademarks and/or  copyrights  thereof shall be the exclusive
         property of HealthCare; and

                  (c) Employee will at HealthCare's  cost, at any and all times,
         furnish such information and assistance,  and execute such applications
         and other  documents as may be requested by  HealthCare  to obtain both
         domestic and foreign patents,  trademarks and/or  copyrights,  title to
         which is to be vested in HealthCare, and Employee gives HealthCare full
         and  exclusive  power  to  prosecute  all  such  applications  and  all
         proceedings in connection therewith.

         6.       TERMINATION.

                  6.1 EXPIRATION OF TERM. If not otherwise terminated under this
Section 6,  Employee's  employment  hereunder shall terminate upon expiration of
the term pursuant to Section 2 hereof.



                                                     - 8 -

                  6.2  DEATH.  The term and Employee's employment
hereunder shall terminate upon Employee's death.

                  6.3 DISABILITY.  In the event Employee  becomes  physically or
mentally  disabled  so as to  become  unable,  for a  period  of  more  than  90
consecutive  working  days or for more than 180  working  days in the  aggregate
during any 365-day period,  to perform his duties  hereunder on  substantially a
full-time basis,  HealthCare may at its option terminate the term and Employee's
employment hereunder upon not less than 30 days' written notice.

                  6.4 TERMINATION  FOR GOOD CAUSE BY HEALTHCARE.  HealthCare may
immediately  terminate the term and  Employee's  employment  hereunder for "Good
Cause." For the purposes of this Section 6.4, "Good Cause" shall mean

                  (a)  Unlawful use or theft of property or monies of
         HealthCare;

                  (b)  Continued willful insubordination as to some
         material matter after reasonable warning or reprimand;

                  (c)  Conviction of a felony or serious misdemeanor
         requiring intent or moral turpitude;

                  (d)  Actively and intentionally pursuing interests of a
         competitor to the detriment of the financial interests of
         HealthCare;

                  (e) Failure to maintain a reasonable  level of job performance
         reasonably satisfactory to HealthCare (including failure to comply with
         the provisions of this Agreement); or

                  (f)  Any   material   breach  by  Employee   of,  or  material
         misrepresentation  in, any  representation,  warranty  or  covenant  of
         Employee in the Merger Agreement.

The  determination  of whether Good Cause  exists shall be made by  HealthCare's
Board of Directors prior to any termination of Employee's employment,  acting in
good faith after a hearing in which Employee, being represented by counsel if he
so desires, has the opportunity to present and defend his case.

                  6.5  TERMINATION  WITHOUT GOOD CAUSE.  This  Agreement  may be
terminated  by  HealthCare  at any time  without  Good Cause.  In the event this
Agreement is terminated  without Good Cause by HealthCare,  HealthCare shall pay
to Employee on the  effective  date of such  termination a lump sum equal to the
salary due Employee for the balance of the term hereof. In addition, pursuant to
Section 3.2 hereof,  Employee is entitled to receive  specified  bonus  payments
during  the  term  of  this  Agreement  ("Bonuses").  In  the  event  Employee's
employment by Hearing Care is terminated without cause:



                                                     - 9 -

                  (i) Prior to the end of the first 12-month  period of the term
         hereof,  Employee  shall be entitled to receive a bonus for such period
         computed  as set forth in Section  3.2 and shall be entitled to receive
         Bonuses during each of the second and third  12-month  periods equal to
         the  greater of (x) the Bonus paid with  respect to the first  12-month
         period or (y) or the Bonuses for such  periods  computed as provided in
         Section 3.2 hereof;

                  (ii) After the first  anniversary of the date hereof but prior
         to the  second  anniversary,  Employee  shall be  entitled  to  receive
         Bonuses  during  each of the second and third  12-month  periods of the
         term hereof  equal to the greater of (x) the Bonus paid with respect to
         the first 12-month period or (y) the Bonuses for such periods  computed
         as provided in Section 3.2 hereof; or

                  (iii)  After the  second  anniversary  of the date  hereof but
         prior to the third  anniversary,  Employee shall be entitled to a Bonus
         for the third  12-month  period of the term hereof equal to the greater
         of (x) the average of the Bonuses  received by Employee with respect to
         first and second  12-month  periods of the term hereof or (y) the Bonus
         for such period computed as provided in Section 3.2.

Termination  without  Good Cause shall occur upon  written  notice to  Employee,
which notice shall specify the effective  date of termination to be no less than
60 days from the date of Employee's  receipt of the notice.  Employee  agrees to
continue to render his normal and usual services  consistent with this Agreement
and his normal  practice  during the entire  60-day  notice  period,  unless the
period  of  rendition  of such  services  is  reduced  or  excused  entirely  by
HealthCare.  Employee shall not be required to seek other employment in order to
mitigate  damages  suffered by Employee as a result of his  termination  without
Good Cause.  Employee shall suffer no reduction or set-off in payment made under
this Section 6.5 due to other employment or compensation.

                  6.6  TERMINATION  FOR GOOD  CAUSE BY  EMPLOYEE.  Employee  may
terminate  this  Agreement  and his  employment  hereunder  for Good Cause.  For
purposes of this Section 6.6, "Good Cause" shall mean (i) the continued material
violation  by  HealthCare  of any of the  provisions  of  this  Agreement  after
HealthCare  has  been  provided  with  written  notice  of  such  violation  and
HealthCare  fails to cure such  violation  within 30 days after  receipt of such
written  notice  or  (ii)  there  has  been  a  "change  of  control"  affecting
HealthCare.  For purposes of this  Section 6.6 a "change of control"  shall mean
that an individual  who is not as of the date hereof a shareholder of HealthCare
acquires 40 percent or more of HealthCare's issued and outstanding common stock.
In the event of a  termination  for Good Cause by  Employee,  Employee  shall be
entitled to receive  severance  pay as provided in Section 6.5 hereof.  Employee
may terminate  this  Agreement at any time on 60 days notice  without Good Cause
but shall, in such case, not be entitled to the benefits of this Section 6.6.

                  6.7  EFFECT  OF  TERMINATION.  Upon  the  termination  of this
Agreement,  the  obligations of the parties  hereunder will cease except for (i)
HealthCare's  obligation to pay Employee all amounts due Employee  hereunder for
services  or  otherwise  accruing  prior  to  the  date  of  termination,   (ii)
HealthCare's  obligation,  if any,  to pay  severance  to  Employee  pursuant to
Sections 6.5 and 6.6 hereof, (iii) Employee's obligations under Sections 4 and 5
hereof, and (iv) the parties' obligations under Sections 7 and 9 hereof.

         7.       ARBITRATION.

                  Except as provided  in Section 4 hereof,  any  controversy  or
disagreement  between Employee and HealthCare  shall be resolved  exclusively by
arbitration  in Los Angeles,  California,  in  accordance  with the rules of the
American  Arbitration  Association and judgment on any award or determination so
made may be entered for  enforcement  in any court having  jurisdiction.  If the
matter in controversy (exclusive of attorney fees and expenses) shall appear, as
at the time of the demand for arbitration,  to exceed $50,000, then the panel to
be appointed shall consist of three neutral arbitrators;  otherwise, one neutral
arbitrator.  The  arbitrator(s)  shall allow such discovery as the arbitrator(s)
determine  appropriate  under the circumstances and shall resolve the dispute as
expeditiously  as practicable,  and if reasonably  practicable,  within 120 days
after the  selection  of the  arbitrator(s).  The  arbitrator(s)  shall give the
parties written notice of the decision,  with the reasons  therefor set out, and
shall have 30 days  thereafter  to  reconsider  and modify such  decision if any
party so requests within ten days after the decision.  Thereafter,  the decision
of the arbitrator(s) shall be final,  binding, and nonappealable with respect to
all persons,  including (without  limitation) persons who have failed or refused
to participate in the arbitration process.

                              EMPLOYMENT AGREEMENT
                                (Vice President)


                  AGREEMENT   dated  as  of  November  1,  1996,  by  and  among
HEALTHCARE CAPITAL CORP., a corporation organized under the laws of the province
of Alberta,  Canada  ("HCC"),  HEALTHCARE  HEARING  CLINICS,  INC., a Washington
corporation ("HealthCare"), and KATHY FOLTNER ("Employee").

                                   RECITALS:

                  A.  HealthCare  operates  audiology and hearing aid clinics in
the United States which provide  services  directly to members of the public and
through referrals from the medical community.

                  B. Employee is a shareholder and an employee of Hearing Health
Services, Inc., a Delaware corporation ("HSI").

                  C. Pursuant to an Asset Purchase Agreement dated as of October
31, 1996 (the "Purchase Agreement"),  Healthcare is acquiring  substantially all
the assets of HSI as a going business.

                  D. Upon the  consummation  of the  purchase of HSI's assets by
HealthCare, HealthCare wishes to employ Employee and Employee wishes to serve in
the employ of HealthCare on the terms and conditions set forth herein.

                  E.  Because  of,  among  other  matters,  Employee's  detailed
knowledge  of HSI and her  reputation  and  relationships  with,  among  others,
clients, customers,  suppliers,  distributors,  and employees of HSI, HealthCare
recognizes  and Employee  acknowledges  the  detrimental  effect on the business
HealthCare is acquiring from HSI and the decreased  value of such business which
would result if Employee were to enter into competition with HealthCare.

                  F. It is a material  condition to  HealthCare's  obligation to
consummate the transaction  provided for in the Purchase Agreement and the other
transactions contemplated thereby that Employee enter into this Agreement.

                                     TERMS:

                  In  consideration  of the  premises  and the mutual  covenants
herein contained, the parties agree as follows:



                                                     - 1 -

         1.       EMPLOYMENT RELATIONSHIP.

                  1.1 EMPLOYMENT.  On the terms and conditions set forth herein,
HealthCare  hereby agrees to employ  Employee and Employee  hereby  accepts such
employment  with HealthCare as Vice  President-Operations.  During the period of
employment,  Employee  shall manage the  operations  of  HealthCare's  audiology
clinics  throughout  North  America and perform  such  additional  services  not
inconsistent  with her position as shall be  designated  by the President or the
Board of  Directors  of  HealthCare  and use her best  efforts  to  promote  the
interests  of  HealthCare.  Employee  understands  that  the  position  of  Vice
President-Operations  is a Portland,  Oregon, based position and that HealthCare
may request employee to relocate her principal  residence to Portland.  Employee
further  understands  that the performance of her duties  hereunder will require
extensive  travel   throughout  the  United  States.  In  light  of  the  travel
requirements of her position,  Company will not initially  request that Employee
relocate to Portland.  Should HealthCare subsequently request that Employee move
to Portland and Employee declines the request,  Employee agrees to either accept
a different  position with  HealthCare at a level of  compensation  commensurate
with such position or to voluntarily resign her employment with HealthCare. Such
resignation  by  Employee  shall  not  affect   HealthCare's  and  HCC's
obligation to make the Cash Earn-Out  Payments (shall have the meaning set forth
in the  Assumption  Agreement  dated as of  October  31,  1996 by and among HCC,
HealthCare,  Employee and HSI) to Employee or HealthCare's obligation on the
Promissory Note dated October 31, 1996 payable to Employee.

                  1.2 EXCLUSIVE  EMPLOYMENT.  During the term of this Agreement,
Employee will devote her full working time, energy,  attention, and skill to her
duties hereunder and to the promotion of HealthCare's business.  During the term
of this  Agreement,  Employee shall not engage in any other  business  activity,
except as mutually  agreed upon by Employee and  HealthCare,  for gain  provided
that this  restriction  shall not be construed to prohibit  Employee from making
personal  investments  in such  form and  manner  as will  neither  require  any
material  amount  of  time or  services  or  violate  any of the  terms  of this
Agreement.

         2.       TERM.

                  This Agreement is being entered into in  contemplation  of the
acquisition by HealthCare of the assets of HSI. Employee's  employment hereunder
shall commence as of the date of closing provided for in the Purchase  Agreement
(the "Closing Date") and shall end on the third  anniversary of such date unless
sooner terminated pursuant to the terms hereof.  Provided Employee's  employment
hereunder has not been earlier  terminated,  upon the  expiration of the initial
term hereof, it shall be renewed and continue for successive additional 12-month
periods until terminated. Either party hereto may terminate this Agreement as of
the end of the initial term or any renewal term


                                                     - 2 -

<PAGE>



by written  notice to the other party given at least 90 days prior to the end of
the initial or a renewal term.

         3.       COMPENSATION.

                  3.1 SALARY.  For her services under this  Agreement,  Employee
shall  receive a salary of $85,000  per year  which  shall be paid  (subject  to
applicable  payroll  withholding  deductions)  in accordance  with  HealthCare's
payroll  policy as in effect from time to time.  For any partial  month  worked,
such salary shall be pro rated on a daily basis.

                  3.2 BENEFITS.  During the term of this  Agreement,  HealthCare
shall  provide to or for the  benefit of Employee  all  benefits  she  currently
receives in connection  with her employment by HSI provided that at such time as
HealthCare  establishes a benefit program for its senior  management  employees,
Employee shall thereafter receive only the benefits provided under such program.
In  addition  to the  foregoing,  HealthCare  shall  provide  to  Employee a car
allowance of $500 per month.  Employee shall also become entitled to participate
in any bonus and profit  sharing plans  HealthCare may establish for the benefit
of its senior management employees.

                  3.3 STOCK  OPTIONS.  HCC shall,  effective  as of the  Closing
Date,  grant to Employee  options to purchase 125,000 shares of the common stock
of HCC ("HCC  Shares").  The option  exercise  price shall be US$1.50 per share.
Provided  Employee  remains  employed by HealthCare as of such dates, the option
shall  become  exercisable  with  respect  to 50 percent of the shares it covers
after the first anniversary of the Closing Date and shall become  exercisable in
full after the second  anniversary  of the Closing Date. It shall be a condition
to  the  exercise  of  such  options  that  Employee   must  make   arrangements
satisfactory to HealthCare for the payment of payroll taxes which HealthCare may
be required to withhold upon such exercise. Such option must be exercised within
a period of five (5) years from the date of the  granting of the  option,  after
which the option shall expire.

                  3.4 LEGENDS ON CERTIFICATES. Certificates representing the HCC
Shares  shall be endorsed  with legends  substantially  in the form set forth in
Exhibit A hereto.

                  3.5 REGISTRATION OF OPTIONS.  HCC shall include the HCC Shares
in any applicable  registration  statement filed by HCC covering shares issuable

         4.       NONDISCLOSURE; NONCOMPETITION.

                  4.1      PROPRIETARY INFORMATION.  Employee acknowledges
that as a result of her prior relationship with HSI and in the
course of her employment with HealthCare, she has acquired and
will learn trade secrets and confidential information of HSI

HealthCare  which if known to competitors  could damage  HealthCare's  business.
Such confidential  information will include,  but not be limited to, some or all
of the following categories of information ("Proprietary Information"):

                  (a)  Financial  Information  including,  but  not  limited  to
         information relating to revenues,  assets,  expenses,  prices,  pricing
         structures,  volume  of  purchases  or sales or  other  financial  data
         whether  related to HealthCare  generally,  or to particular  products,
         services, geographic areas, or time periods;

                  (b) Supply and service information including,  but not limited
         to information  relating to suppliers'  names and  addresses,  terms of
         supply and service contracts or of particular transactions, and related
         information   about  potential   suppliers  to  the  extent  that  such
         information  is not  generally  known to the public,  and to the extent
         that the  combination  of suppliers  or use of a  particular  supplier,
         though  generally known or available,  yields  advantages to HealthCare
         the details of which are not generally known;

                  (c)  Marketing  information  including,  but  not  limited  to
         information  relating  to  details of  ongoing  or  proposed  marketing
         programs or agreements by or on behalf of HealthCare,  sales forecasts,
         advertising  formats  and  methods or results of  marketing  efforts or
         information about impending transactions;

                  (d)  Personnel  information  including,  but  not  limited  to
         information relating to personal or medical histories,  compensation or
         other  terms of  employment,  actual or proposed  promotions,  hirings,
         resignations,  disciplinary actions, terminations or reasons therefore,
         training  methods,   performance,   or  other  information   concerning
         employees of HealthCare; and

                  (e)  Client   information   including,   but  not  limited  to
         information  relating to past, existing or prospective  client's names,
         addresses  or  backgrounds,  records  of  treatment,  terms of sales or
         agreements between clients and HealthCare,  status of clients' accounts
         or credit, or related  information about actual or prospective  clients
         as well as client lists.

                  Employee   agrees   to  keep   all   Proprietary   Information
confidential.  Except as may be  necessary in the  performance  of her duties on
behalf of HealthCare,  Employee will make no use of and will not  communicate or
divulge to any party whatsoever any Proprietary  Information.  Employee will not
at any time after her employment with HealthCare  terminates use any Proprietary
Information for her own benefit or on behalf of any person, firm,


                                                     - 4 -

<PAGE>



partnership,  association, corporation, or other party whatsoever. This covenant
shall  not  apply  to any  information  that  by  means  other  than  Employee's
deliberate  or  inadvertent  disclosure  becomes  well known to the public or to
disclosure  compelled by judicial or  administrative  proceedings after Employee
diligently (at HealthCare's  expense) tries to avoid each disclosure and affords
HealthCare the opportunity to obtain  assurance that compelled  disclosures will
receive confidential treatment.

                  4.2 OWNERSHIP AND RETURN OF  DOCUMENTS.  Employee  agrees that
all records or materials  (written or in computer format),  notes,  memoranda or
other documents and all copies thereof relating to Proprietary Information, some
of which may be prepared by Employee,  and all objects  associated  therewith in
any way shall be  HealthCare's  property.  Employee shall not,  except as may be
necessary for use in HealthCare's business operations,  copy or duplicate any of
the  aforementioned  documents  or objects,  nor remove  them from  HealthCare's
facilities  nor use any  information  concerning  them  except for  HealthCare's
benefit,  either during her employment or thereafter.  Employee  agrees that she
will deliver all of the aforementioned  documents and objects that may be in her
possession to HealthCare on termination of her employment,  or at any other time
on HealthCare's  request,  together with her written certification of compliance
with the provisions of this Section 4.2.

                  4.3 NONSOLICITATION  AND NONCOMPETITION.  Employee agrees that
during the term of this  Agreement and for a period of 36 full  calendar  months
following the termination of Employee's employment hereunder, whereby HealthCare
terminates  for Good Cause (as defined in Section  6.4) or  Employee  terminates
without Good Cause, Employee will not, directly or indirectly, for herself or on
behalf of any other party:

                  (a) Be engaged  directly or  indirectly  (as an  individual or
         stockholder,  officer,  director,  partner, agent, employee,  direct or
         indirect owner or  representative of any person,  firm,  corporation or
         association) in any audiology and hearing aid multi-clinic  business of
         national  scope  competitive  with the  business  being  carried  on by
         HealthCare at such time of termination;

                  (b) Participate in, assist,  engage in, advise or consult for,
         lend money to,  guarantee the debts or obligations  of, permit her name
         to be used by or in any way be connected with any audiology and hearing
         aid multi-clinic business of national scope similar in nature to all or
         any part of HealthCare's business or which competes in multiple regions
         with HealthCare's business;

                  (c) Call upon or endeavor to transact  business in competition
         with HealthCare with any audiology and hearing aid  multi-clinic  party
         of  national  scope who was a client or customer  of  HealthCare  while
         Employee was employed hereunder


                                                     - 5 -

<PAGE>



         (such period being hereinafter referred to as the "Employment Period");
         or

                  (d) Disturb, hire, entice away or in any other manner persuade
         any employee,  client,  or customer of HealthCare  who was an employee,
         client,  or customer of HealthCare  during the  Employment  Period,  to
         alter,   modify  or  terminate  his,  her,  or  its  relationship  with
         HealthCare as an employee, client, or customer as the case may be.

Notwithstanding  the  foregoing,  Employee may be a passive  investor in up to 5
percent of the stock of any publicly traded company.

                  4.4 REMEDIES  FOR BREACH.  Employee  acknowledges  that in the
event of her breach of this Section 4,  damages will be difficult or  impossible
to ascertain,  and it is therefore agreed that  HealthCare,  in addition to, and
without  limiting any other remedy or right it may have, shall have the right to
an injunction enjoining said breach issued by a court of competent jurisdiction.
In the event any litigation or controversy between the parties hereto arises out
of or in connection with this Agreement, the prevailing party in such litigation
or controversy  shall be entitled to recover from the other party all reasonable
attorney fees, expenses and costs, including those associated with any appellate
proceedings or post-judgment collection proceedings.

         5.       DEVELOPMENTS.

                  There shall become the exclusive  property of HealthCare every
invention and  improvement  conceived,  invented or developed by Employee during
the term hereof and for a period of one year thereafter relating to or usable in
(i) any business then being carried on or actively contemplated by HealthCare or
(ii) the production of any product then being manufactured, sold, used or in the
process of development by HealthCare or which may be sold or used in competition
with any such product.  With respect to all such inventive  ideas  originated or
developed  by  Employee  while in the  employ of  HealthCare,  or  developed  by
Employee within the period of one year thereafter,  which relate to the business
or related products,  designs,  ideas or techniques sold, used or in the process
of  development  by  HealthCare  during the term,  or as to which  Employee  has
acquired information as a result of such employment, and all patents, trademarks
and/or copyrights obtained on such inventive ideas:

                  (a) Employee agrees to disclose and assign, without charge but
         at  HealthCare's  cost,  all  such  inventive  ideas  and any  patents,
         trademarks and/or copyrights obtained thereon to HealthCare;

                  (b)  Employee  agrees  that all such  inventive  ideas and any
         patents,  trademarks and/or  copyrights  thereof shall be the exclusive
         property of HealthCare; and


                                                     - 6 -

<PAGE>




                  (c) Employee will at HealthCare's  cost, at any and all times,
         furnish such information and assistance,  and execute such applications
         and other  documents as may be requested by  HealthCare  to obtain both
         domestic and foreign patents,  trademarks and/or  copyrights,  title to
         which is to be vested in HealthCare, and Employee gives HealthCare full
         and  exclusive  power  to  prosecute  all  such  applications  and  all
         proceedings in connection therewith.

         6.       TERMINATION.

                  6.1 EXPIRATION OF TERM. If not otherwise terminated under this
Section 6,  Employee's  employment  hereunder shall terminate upon expiration of
the term pursuant to Section 2 hereof.

                  6.2 DEATH. The term and Employee's  employment hereunder shall
terminate upon Employee's  death.  Such death shall not affect  HealthCare's
and  HCC's  obligation  to make the Cash  Earn-Out  Payments  to Employee or
HealthCare's  obligation  on the  Promissory  Note dated  October  31,  1996
payable to Employee.

                  6.3 DISABILITY.  In the event Employee  becomes  physically or
mentally  disabled  so as to  become  unable,  for a  period  of  more  than  90
consecutive  working  days or for more than 180  working  days in the  aggregate
during any 365-day period,  to perform her duties  hereunder on  substantially a
full-time basis,  HealthCare may at its option terminate the term and Employee's
employment hereunder upon not less than 90 days' written notice.

                  6.4 TERMINATION  FOR GOOD CAUSE BY HEALTHCARE.  HealthCare may
immediately  terminate the term and  Employee's  employment  hereunder for "Good
Cause." For the purposes of this Section 6.4, "Good Cause" shall mean

                  (a) Unlawful use or theft of property or monies of HealthCare;

                  (b)  Continued  willful  insubordination  as to some  material
         matter after reasonable warning or reprimand;

                  (c)  Conviction of a felony or serious  misdemeanor  requiring
         intent or moral turpitude;

                  (d)  Actively  and  intentionally   pursuing  interests  of  a
         competitor to the detriment of the financial interests of HealthCare;

                  (e) Failure, after 90 days notice or in the event such failure
         is of such a nature that it cannot be completely remedied within the 90
         day period,  such failure shall not  constitute  Good Cause if Employee
         begins  correcting the claimed  failure  within the 90 day period,  and
         thereafter proceeds with reasonable diligence and in good faith to


                                                     - 7 -

<PAGE>



         effect a remedy as soon as practicable  to maintain a reasonable  level
         of job performance  reasonably  satisfactory  to HealthCare  (including
         failure to comply with the provisions of this Agreement); or

                  (f)  Any   material   breach  by  Employee   of,  or  material
         misrepresentation  in, any  representation,  warranty  or  covenant  of
         Employee in the Purchase Agreement.

The  determination  of whether Good Cause  exists shall be made by  HealthCare's
Board of Directors acting in good faith after a hearing in which Employee, being
represented  by counsel if she so desires,  has the  opportunity  to present and
defend her case.

Such termination shall not affect  HealthCare's  and HCC's obligation to
make the Cash Earn-Out  Payments to Employee or  HealthCare's  obligation on
the Promissory Note dated October 31, 1996 payable to Employee.

                  6.5  TERMINATION  WITHOUT GOOD CAUSE.  This  Agreement  may be
terminated  by  HealthCare  at any time  without  Good Cause.  In the event this
Agreement is terminated  without Good Cause by HealthCare,  HealthCare shall pay
to Employee on the  effective  date of such  termination a lump sum equal to the
salary due Employee for the balance of the term hereof.

Termination  without  Good Cause shall occur upon  written  notice to  Employee,
which notice shall specify the effective  date of termination to be no less than
60 days from the date of Employee's  receipt of the notice.  Employee  agrees to
continue to render her normal and usual services  consistent with this Agreement
and her normal  practice  during the entire  60-day  notice  period,  unless the
period  of  rendition  of such  services  is  reduced  or  excused  entirely  by
HealthCare.  Employee shall not be required to seek other employment in order to
mitigate  damages  suffered by Employee as a result of her  termination  without
Good Cause;  Employee shall suffer no reduction or set-off in payment made under
this Section 6.5 due to other employment or compensation.

Such termination shall not affect  HealthCare's  and HCC's obligation to
make the Cash Earn-Out  Payments to Employee or  HealthCare's  obligation on
the Promissory Note dated October 31, 1996 payable to Employee.

                  6.6  TERMINATION  FOR GOOD  CAUSE BY  EMPLOYEE.  Employee  may
terminate  this  Agreement  and her  employment  hereunder  for Good Cause.  For
purposes of this Section 6.6, "Good Cause" shall mean (i) the continued material
violation  by  HealthCare  of any of the  provisions  of  this  Agreement  after
HealthCare  has  been  provided  with  written  notice  of  such  violation  and
HealthCare  fails to cure such  violation  within 30 days after  receipt of such
written  notice  or  (ii)  there  has  been  a  "change  of  control"  affecting
HealthCare. For purposes of this Section 6.6 a "change


                                                     - 8 -

<PAGE>



of  control"  shall mean that an  individual  who is not as of the date hereof a
shareholder of HealthCare acquires 40 percent or more of HealthCare's issued and
outstanding  common  stock.  In the  event of a  termination  for Good  Cause by
Employee,  Employee  shall be entitled to receive  severance  pay as provided in
Section 6.5 hereof. Employee may terminate this Agreement at any time on 60 days
notice  without  Good Cause but  shall,  in such case,  not be  entitled  to the
benefits of this Section 6.6. Such termination shall not affect HealthCare's
and  HCC's  obligation  to make the Cash  Earn-Out  Payments  to Employee or
HealthCare's  obligation  on the  Promissory  Note dated  October  31,  1996
payable to Employee.

                  6.7  EFFECT  OF  TERMINATION.  Upon  the  termination  of this
Agreement,  the  obligations of the parties  hereunder will cease except for (i)
HealthCare's  obligation to pay Employee all amounts due Employee  hereunder for
services  or  otherwise  accruing  prior  to  the  date  of  termination,   (ii)
HealthCare's  obligation,  if any,  to pay  severance  to  Employee  pursuant to
Sections 6.5 and 6.6 hereof, (iii) Employee's obligations under Sections 4 and 5
hereof, and (iv) the parties' obligations under Sections 7 and 9 hereof.

Such termination shall not affect  HealthCare's  and HCC's obligation to
make the Cash Earn-Out  Payments to Employee or  HealthCare's  obligation on
the Promissory Note dated October 31, 1996 payable to Employee.

         7.       ARBITRATION.

                  Except as provided  in Section 4 hereof,  any  controversy  or
disagreement  between Employee and HealthCare  shall be resolved  exclusively by
arbitration in Portland,  Oregon,  in accordance  with the rules of the American
Arbitration  Association and judgment on any award or  determination so made may
be entered for  enforcement in any court having  jurisdiction.  If the matter in
controversy  (exclusive of attorney fees and expenses)  shall appear,  as at the
time of the  demand for  arbitration,  to exceed  $50,000,  then the panel to be
appointed  shall consist of three neutral  arbitrators;  otherwise,  one neutral
arbitrator.  The  arbitrator(s)  shall allow such discovery as the arbitrator(s)
determine  appropriate  under the circumstances and shall resolve the dispute as
expeditiously  as practicable,  and if reasonably  practicable,  within 120 days
after the  selection  of the  arbitrator(s).  The  arbitrator(s)  shall give the
parties written notice of the decision,  with the reasons  therefor set out, and
shall have 30 days  thereafter  to  reconsider  and modify such  decision if any
party so requests within ten days after the decision.  Thereafter,  the decision
of the arbitrator(s) shall be final,  binding, and nonappealable with respect to
all persons,  including (without  limitation) persons who have failed or refused
to participate in the arbitration process.

         8.       ASSIGNMENT.

                  Each  party  acknowledges  that  this  is a  personal  service
contract and that no assignment of this Agreement or any interest therein may be
made by either  party  without the express  written  consent of the other.  This
Agreement   shall  be  assignable   and   transferable   by  HealthCare  to  any
successor-in-interest, parent, subsidiary, or affiliate of HealthCare.

         9.       GENERAL.

                  9.1  GOVERNING  LAW.  This  Agreement  shall be subject to and
governed by the laws of the State of Oregon,  excluding  any choice of law rules
that may direct the application of the laws of another jurisdiction.

                  9.2 BINDING  EFFECT.  This Agreement shall be binding upon and
inure to the benefit of  HealthCare  and  Employee and their  respective  heirs,

assigns.

                  9.3 INTEGRATION;  AMENDMENT; WAIVER. This Agreement sets forth

employment  agreement by and between  Employee and HSI dated  December 23, 1994,

hereof.  No change or  modification  of this Agreement  shall be valid unless in

any provision of this Agreement  shall be valid unless written and signed by the
person or party to be charged.

                  9.4 SEVERABILITY.  If any provision of this Agreement shall be
determined to be  unenforceable  because the terms are excessive or unreasonable
then  such  provision  shall be  reduced  to the  maximum  reasonable  limit and
enforced  as  reduced.  In the  event  that  any one or  more of the  provisions
contained in this  Agreement  shall be  determined  to be invalid,  illegal,  or
unenforceable  in any respect,  the  enforceability  of such provisions in every
other respect and of the remaining provisions of this Agreement shall not in any
way be impaired.

         IN WITNESS  WHEREOF,  this  Agreement  has been executed as of the date
first above-written.

                               (CANADIAN DOLLARS)


To:      FRASERVIEW HEARING AND SPEECH CLINICS LTD.     Date:    AUGUST 21, 1995

         (Name of customer)
         #350-6091 GILBERT ROAD
         RICHMOND, B.C.  V7C-5L9
         (Address)

Dear Sirs:

In  consideration  of ROYAL BANK OF CANADA  (the  "Bank")  providing  you with a
revolving  demand loan facility (the "Loan Facility") in the principal amount of
up   to   $50,000    (figures)    Fifty    Thousand    and    00/100------------
- -----------------------Dollars,  at our unit of  account  located  at 1025  West
Georgia Street, Vancouver, B.C. (unit address), the Customer agrees (and each of
them, if more than one, jointly and severally  agrees) with the Bank as follows:

1.       The  Customer  promises  to pay to  the  Bank  on  demand  all  amounts
         outstanding under this Loan Facility including principal, interest, and
         any charges,  together with interest thereon calculated at a rate equal
         to the Bank's  Prime Interest Rate per annum in effect from time to
         time  plus 1% per  annum,  interest  shall  be  calculated  monthly  in
         arrears,  both before and after maturity,  default and judgment, on the
         daily  balance  outstanding  at the  aforementioned  rate  based on the
         actual number of days elapsed  divided by 365, with interest on overdue
         interest at the same rate as on the principal,  and shall be payable on
         the 20 day of each month.  On the date hereof such Prime  Interest Rate
         is 8 1/4% per annum.

         The Prime  Interest Rate is the annual rate of interest  announced from
         time  to time  by the  Bank as a  reference  rate  then in  effect  for
         determining  interest  rates on  Canadian  dollar  commercial  loans in
         Canada.

2.       The Customer  authorizes  the Bank,  but the Bank is not obliged,  from
         time to time to debit Account #1316322  (transit 10) with the amount of
         interest accrued and unpaid by the Customer.  The Customer acknowledges
         the Bank may withdraw any undrawn  portion of the Loan  Facility at any
         time without notice.

3.       Provided  that  the  Bank  has  not  demanded  payment  of  any  amount
         outstanding  under  this  Loan  Facility,  or has not  terminated  this
         agreement, the Customer may borrow, repay and reborrow up to the amount
         remaining  available under this Loan Facility at any time and from time
         to time in the following manner:

         b.       The Customer  authorizes  the Bank,  daily or otherwise as and
                  when determined by the Bank from time to time to ascertain the
                  position  or net  position  (as the case may be)  between  the
                  Customer and the Bank in respect to the deposit account, or if
                  more than one, the deposit accounts maintained by the Customer
                  with the Bank (the "Account") and that

                  (1)      if such  position  or net  position  is a  credit  in
                           favour  of the  Customer,  the Bank  will  apply  the
                           amount of such credit or any part thereof, rounded to
                           the  nearest  $5,000  as  a  repayment  of  the  Loan
                           Facility,  and the Bank will debit the  Account  with
                           the amount of such repayment, and



                                                     - 1 -

                  (2)      if such position or net position is a debit in favour
                           of the Bank,  the Bank will make an advance under the
                           Loan Facility of such amount,  rounded to the nearest
                           $5,000 as is  required  to place the  Account in such
                           credit  or net  credit  position  as has been  agreed
                           between the Customer and the Bank from time to time,

         provided  that at no time shall the balance  owing exceed the amount of
         the Loan Facility.

                  The Customer  authorizes  the Bank to debit  account  #1316322
                  (transit  10) with a specified  fee per month as may be agreed
                  between  the Bank and the client  from time to time.  This fee
                  may be  packaged  with  fees for  other  products/services  as
                  negotiated with the customer.

                  The  foregoing  fees and  revolvement  amount will be reviewed
                  annually  by the Bank.  Following  such  review,  the Bank may
                  renegotiate the fees and revolvement amount with the Customer,
                  and may revise the fees and revolvement amount upon giving the
                  Customer  30  days'  prior  written  notice  mailed to the
                  Customer at the most recent address known to the Bank.

4.       The  Customer  agrees to maintain  an average  monthly  minimum  credit
         balance in the  Account,  which may  include  compensating  balances to
         cover non-lending services fees, reserves and debit float. Such balance
         shall be:

         a.       $-0-, OR

5.       The Bank shall  maintain on the books of its unit of account,  accounts
         and records evidencing the outstanding  principal amount of the loan of
         the Bank to the Customer  under this Loan  Facility  together  with any
         interest in respect  thereof.  The Bank shall  maintain a record of the
         amount of the balance,  each advance, and each payment of principal and
         interest on account of the loan.  The  Bank's  accounts and records
         constitute in the absence of manifest error prima facie evidence of the
         indebtedness of the Customer to the Bank under this Loan Facility.

6.       The Customer  acknowledges that the outstanding principal balance owing
         to the Bank under existing  revolving demand loan agreement,  or as the
         case may be, existing  operating  loans, is $-0- (figures) Zero Dollars
         (words) as at the close of  business on August  (month) 18 (day),  1995
         (year).  The  initial  outstanding  principal  balance  under this loan
         facility  will be  adjusted  to  reflect  transactions  under the above
         credit facilities occurring between August 18 (month/day), 1995 (year),
         and the date of  acceptance  of this  agreement.  Interest  on  amounts
         outstanding  under  the  above  credit  facilities  from  the  date  of
         acceptance  hereof will be at the rate set forth in paragraph 1 of this
         agreement.  The  Customer  acknowledges  that  the  security  interests
         previously granted to the Bank continue to enure to the Bank.

7.       a. The Customer  acknowledges  that the terms of this  agreement are in
         addition to and not in substitution for any terms and conditions of any
         other agreements between the Customer and the Bank.

         Please  acknowledge  acceptance  of the  terms and  conditions  of this
         agreement by signing a copy on or before September 15 (month/day), 1995
         (year), and returning it to the undersigned.

At the Closing,  Purchaser  shall pay the Purchase Price to Sellers by certified
or cashier's check.

         1.4 Purchase Price Adjustments.  The Purchase Price shall be subject to

         Closing,  Sellers shall  reimburse  Purchaser on a pro rata basis in an
         amount equal to the total of the accounts  receivable  reflected on the
         Statement of Net Working  Capital (as defined in  subsection  1.4(c)(i)
         below) net of the allocable portion of the reserve for bad debts, which
         remain  uncollected  as of such date  provided that with respect to the
         accounts  receivable  listed on Schedule  1.4(a) attached  hereto,  the
         reimbursement  date shall be the first anniversary of the Closing date.

         to the  accounts  receivable  listed on  Schedule  1.4(a),  Sellers may
         participate in the collection process of such accounts  receivable.  In
         the  event  the  total  amount   collected  with  respect  to  accounts
         receivable  reflected on the Statement of Net Working  Capital  exceeds
         the amount of such accounts  receivable net of the  applicable  reserve
         for bad debts,  Purchaser  shall pay the excess to Sellers  pro rata on
         the 200th day following Closing.

                  (b) Liabilities.  Sellers  acknowledge that the Purchase Price
         was negotiated on the  assumption  that Company would have no long-term
         liabilities,  including  debt. In the event that at Closing Company has
         long-term  liabilities,  Sellers shall pay to Purchaser,  on a pro rata
         basis, an amount equal to the total of any such long-term liabilities.

                  (c) Net Working Capital Adjustment.

                  of  the  Closing   date  will  not  be  included  in  accounts
                  receivable  and (ii) all payments made by Company with respect
                  to such hearing aid orders shall be treated as prepaid items.

                           (ii)  As  promptly  as   practicable   following  the
                  Closing,  but in no  event  later  than  45  days  thereafter,
                  Sellers and Purchaser  shall cooperate in preparing a mutually
                  agreeable statement of the Net Working Capital which shall set
                  forth the  computation  and  components  thereof in reasonable
                  detail (the "Statement of Net Working Capital").

                           (iii) On the  fifteenth  day  after the date on which
                  the  Statement of Net Working  Capital is  completed  (or such
                  earlier  date as such  statement  is  mutually  agreed upon by
                  Sellers and  Purchaser in writing),  (i) in the event that the
                  Net Working Capital exceeds $150,000, then Purchaser shall pay

                  Sellers  shall pay to Purchaser,  pro rata,  the amount of the
                  deficiency.

                  (d)  Reimbursement  of Sick and Vacation Pay. In preparing the
         Statement  of Net  Working  Capital it has been  agreed that no accrual
         shall be made for sick and vacation pay  entitlements  for employees of
         Company. In consideration of this exclusion, Sellers agree to reimburse
         Purchaser  for any sick or vacation pay payments  Purchaser is required
         to  make to  former  employees  of  Company  who  become  employees  of
         Purchaser  and whose  employment  terminates  for any reason within the
         first six months following the Closing date to the extent such payments

respect to certain leases,  line of credit agreements,  purchase agreements with
manufacturers,  or other agreements for the benefit for the Company,  including,
without  limitation,  those  described on Schedule  5.2.  Following the Closing,
Purchaser  will use its best  efforts to obtain the release of the Sellers  from

obtained, Purchaser will indemnify and hold the Sellers harmless with respect to
any  loss,  cost,  or  expense  the  Sellers  may incur as a result of not being
released.

                  indemnification  with  respect to such  Seller's  warranty  of

                           (v) Any Claims shall be asserted by Purchaser jointly
                  against Sellers on a uniform basis and any waiver,  compromise
                  or settlement of a Claim offered by Purchaser shall be offered
                  on the same terms to all Sellers.

                  (b) Purchaser's right to  indemnification  as provided in this
         Section 8.1 shall not be eliminated,  reduced or modified in any way as
         a result  of the fact  that (i)  Purchaser  had  notice  of a breach or
         inaccuracy of any representation, warranty or covenant contained herein
         (except as set forth in the  Disclosure  Schedule),  (ii) Purchaser had
         been provided with access,  as requested by Purchaser,  to officers and
         employees  of the  Company  and  such of  Company's  books,  documents,
         contracts  and records as has been provided to Purchaser in response to
         Purchaser's requests.

         8.2 Indemnification by Purchaser. Purchaser hereby agrees to indemnify,
defend,  and hold  harmless  the Sellers  from and  against all Claims  asserted
against,  resulting to,  imposed  upon,  or incurred by the Sellers  directly or
indirectly by reason of, arising out of, or resulting from (a) the inaccuracy or
breach of any  representation  or warranty  of  Purchaser  contained  in or made
pursuant to this Agreement or in any of the documents delivered pursuant hereto,
or (b) the  non-performance  or breach of any covenant,  term or provision to be
performed by Purchaser  contained in this  Agreement or in any of the  documents
delivered pursuant hereto. The indemnification obligation of Purchaser hereunder
is with respect to the full amount of the Claims.

         8.3  Notice;  Defense  of  Claims.  If a claim is to be made by a party
entitled   to   indemnification   hereunder,   the   party   entitled   to  such
indemnification  shall give written notice to the indemnifying party immediately
after the party entitled to indemnification becomes aware of any fact, condition
or event  which  may give  rise to a matter  for  which  indemnification  may be
sought; provided that the failure of any indemnified party to give timely notice
shall not affect the rights to  indemnification  hereunder  except to the extent
that the indemnifying party  demonstrates  actual damage caused by such failure.
If any lawsuit or enforcement  action is filed against any party entitled to the
benefit of indemnity hereunder,  and if the indemnifying party shall acknowledge
in  writing  to the  indemnified  party  that the  indemnifying  party  shall be
obligated  under the terms of its indemnity  hereunder in  connection  with such
lawsuit,  action or claim, then the indemnifying party shall be entitled,  if it
so elects,  to take control of the defense and  investigation of such lawsuit or
action and to employ and engage attorneys of its own choice to handle and defend
the same, at the  indemnifying  party's cost, risk and expense provided that the
indemnifying  party and its counsel  shall  proceed with  diligence  and in good
faith with  respect  thereto.  The  indemnified  party  shall  cooperate  in all
reasonable  respects  with the  indemnifying  party  and such  attorneys  in the
investigation,  trial and  defense  of such  lawsuit  or action  and any  appeal
arising therefrom; provided, however, that the indemnified party may, at its own
cost,  participate  in the  investigation,  trial and defense of such lawsuit or
action and any appeal arising therefrom.

         8.4 Survival of  Representations.  All  representations  and warranties
made by the  parties  in this  Agreement  are  made  only as of the date of this
Agreement but will survive the consummation of the transactions  contemplated by
this Agreement until October 31, 1998

                  failed  to  perform  any of the  representations,  warranties,
                  covenants,   or   agreements  of  this   Agreement   prior  to

instrument  in writing  signed on behalf of the party  granting the extension or

legal  representatives.  This  Agreement  is not  assignable  and any  purported

         9.11     Resolution of Disputes.

                  (a) Arbitration. Any dispute, controversy or claim arising out
         of or relating to this  Agreement or the  performance by the parties of
         its terms shall be settled by binding  arbitration held in Los Angeles,
         California,  in accordance with the Commercial Arbitration Rules of the
         American Arbitration Association then in effect, except as specifically
         otherwise provided in this Section 9.11. Notwithstanding the foregoing,
         HealthCare,   in  its  discretion,   apply  to  a  court  of  competent
         jurisdiction  for  equitable  relief from any  violation or  threatened
         violation of the covenants of the Shareholders  under Section 5.1(b) of
         this Agreement.

                  (b)  Arbitrators.  If the matter in controversy  (exclusive of
         attorney fees and expenses) shall appear,  as at the time of the demand
         for  arbitration,  to exceed  $50,000,  then the panel to be  appointed
         shall  consist of three  neutral  arbitrators;  otherwise,  one neutral
         arbitrator.

                  (c) Procedures;  No Appeal. The arbitrator(s) shall allow such
         discovery  as  the  arbitrator(s)   determine   appropriate  under  the
         circumstances  and  shall  resolve  the  dispute  as  expeditiously  as
         practicable,  and if reasonably practicable,  within 120 days after the
         selection  of the  arbitrator(s).  The  arbitrator(s)  shall  give  the
         parties written notice of the decision,  with the reasons  therefor set
         out,  and shall have  thirty (30) days  thereafter  to  reconsider  and
         modify  such  decision  if any party so  requests  within ten (10) days
         after the decision. Thereafter, the decision of the arbitrator(s) shall
         be final,  binding,  and  nonappealable  with  respect to all  persons,
         including  (without  limitation)  persons who have failed or refused to
         participate in the arbitration process.

                  (d) Authority. The arbitrator(s) shall have authority to award
         relief  under  legal or  equitable  principles,  including  interim  or
         preliminary relief, and to allocate responsibility for the costs of the
         arbitration and to award recovery of attorney fees and expenses in such
         manner as is determined to be appropriate by the arbitrator(s).

                  (e) Entry of Judgment. Judgment upon the award rendered by the
         arbitrator(s)  may be  entered  in any  court  having in  personam  and
         subject matter  jurisdiction.  The Shareholders  and HealthCare  hereby
         submit to the in personam  jurisdiction of the federal and state courts
         in California for the purpose of confirming any such award and entering
         judgment thereon.

                  (f) Confidentiality.  All proceedings under this Section 9.11,
         and  all  evidence  given  or  discovered  pursuant  hereto,  shall  be
         maintained in confidence by all parties.

                  (g)   Continued   Performance.   The  fact  that  the  dispute
         resolution  procedures  specified in this Section 13 shall have been or
         may be invoked shall not excuse any


                                                     - 22 -

         rights to terminate this Agreement that may be available to any party.

         9.12  Governing  Law. This  Agreement may not be modified or terminated
orally, and shall be construed and interpreted  according to the internal law of
the state of  California,  excluding any choice of law rules that may direct the
application of the laws of another jurisdiction.

         9.13 Counterparts. This Agreement may be executed by the parties hereto
in separate counterparts,  each of which when so executed and delivered shall be
an original,  but all such  counterparts  shall together  constitute one and the
same instrument.  Each counterpart may consist of a number of copies hereof each
signed by less than all, but together signed by all, of the parties hereto.

will  cooperate  in good faith  with the  others  and will take all  appropriate
action and execute any documents,  instruments,  or conveyances of any kind that
may be  reasonable  necessary or desirable to carry out any of the  transactions
contemplated hereunder.

         9.16 Sellers  Action.  Whenever in this Agreement the Sellers are given
the  discretion  to take or not to take any action,  the decision of the Sellers
shall be made  pursuant  to the vote of the  Sellers  holding a majority  of the
Shares.

         9.17  Termination  of  Restrictions.   Upon  the  consummation  of  the
