ITEM 1. DESCRIPTION OF BUSINESS.

OVERVIEW

         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,  when it acquired nine
hearing care centers in British Columbia. The Company did not begin operating in
the United  States until it purchased two hearing care centers near Santa Maria,
California,  in July 1996. By vote of the shareholders,  the Company changed its
name from HealthCare  Capital Corp. to Sonus Corp. in February 1998, and changed
its  jurisdiction of  incorporation  from Alberta,  Canada,  to Yukon Territory,
Canada, in December 1998. The Company, through its subsidiaries Sonus-USA,  Inc.
("Sonus-USA"),   Sonus-Texas,   Inc.  ("Sonus-Texas"),   and  Sonus-Canada  Ltd.
("Sonus-Canada"),  currently  owns and  operates 99 hearing  care centers in the
United  States and Western  Canada.  Centers owned by the Company are located in
the states of Arizona,  California,  Illinois,  Michigan,  Missouri, New Mexico,
Oregon,  Texas, and Washington and in the Canadian provinces of British Columbia
and Alberta.  The Company  intends to expand its network of hearing care centers
by acquiring centers in its existing as well as new geographic markets.

         Each  of the  Company's  hearing  care  centers  provides  its  hearing
impaired  patients  with a full range of  audiological  products  and  services.
During the fiscal year ended July 31, 1999,  approximately  86% of the Company's
revenues  were  derived  from  product  sales,  including  hearing  instruments,
batteries, and accessories,  10% were derived from audiological services, and 4%
were from other sources.

                                      -1-
<PAGE>

Substantially  all of the  Company's  hearing  care  centers  are  staffed  with
audiologists.  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 and hearing instrument dispensers,  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,  through its subsidiary Hear PO Corp., also operates as an
independent provider association and hearing care benefit administrator. Hear PO
Corp.  obtains  contracts to provide hearing care benefits to managed care group
and  corporate  health  care  organizations   through  its  approximately  1,100
affiliated audiologists,  sells Hear PO brand private label hearing instruments,
and operates as a buying group for its affiliated audiologists.

         The Company, through Sonus-USA,  operates a franchise licensing program
called  The Sonus  Network.  Licensees  are  entitled  to use the Sonus name and
receive other benefits such as practice  management  advice and training,  group
buying discounts, and marketing services. There are currently 64 licensees under
the licensing program with 116 locations in 20 states.

         In August 1999, the Company launched its e-commerce program through its
internet  site  at  www.sonus.com.   Products  that  can  be  purchased  through
www.sonus.com include gift certificates, hearing instrument batteries, assistive
listening  devices,   hearing  protection  items,   educational  materials,  and
audiology  equipment,   supplies  and  accessories.   Audiologists  and  hearing
instrument  dispensers can also purchase hearing instruments for resale to their
patients.  The Company believes that e-commerce poses substantial  opportunities
for revenue growth and intends to continue to devote  resources to enhancing its
web site and increasing product availability and differentiation.

INDUSTRY BACKGROUND

Professionals  and  Centers.  Hearing  instruments  may be dispensed by either a
dispensing audiologist or a hearing instrument specialist ("HIS"). Although both
audiologists  and  HISs  may  be  licensed  to  dispense  hearing   instruments,
audiologists  have  advanced  training in audiology and hold either a masters or
Ph.D. degree.

         The June 1998 issue of The Hearing  Review,  a hearing  industry  trade
journal,  indicates that  approximately  24% of HISs in the U.S. are at least 61
years of age,  30% are 51-60  years of age,  33% are 41-50 years of age and only
13% are age 40 or under,  compared to 5%, 21%,  45% and 29%,  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
audiologists  and  HISs  will  find it  increasingly  attractive  to sell  their
practices to or affiliate with larger organizations, such as the Company.

                                      -2-
<PAGE>

         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 center 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.  According to the 1996  edition of  Communication
Facts, published by the American Speech-Language Hearing Association, the number
of  persons  in the  United  States who have  hearing  loss is  estimated  to be
approximately  28 million and the percentage of individuals  with a hearing loss
relative to the general  population is approximately 2% for those under 18 years
of age, 5% for those  between 18 and 44 years of age,  14% for those  between 45
and 64 years of age,  23% for those  between 65 and 74 years of age, and 32% for
those over 75 years of age.  In  addition,  the  American  Tinnitus  Association
estimates that approximately 12 million American adults have tinnitus (a ringing
sensation in the ears) that is severe enough to seek medical help.

         The  Company  believes  that the widely  recognized  demographic  trend
toward an aging population will increase the demand for hearing instrument sales
and audiological  services and that the demand for hearing  instruments that are
less visible and for newer and superior hearing instrument  technology,  such as
digital and  programmable  hearing  instruments,  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  instrument and that the demand for hearing instrument 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:

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

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

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

         otolaryngologic   services,   including   surgery  and  other   medical
         treatment.

         The  Company's  centers   primarily   provide  hearing   rehabilitation
services. The Company has two facilities,  one located in Calgary,  Alberta, and
the other in Orange County,  California,  that provide advanced audio-diagnostic
services  and  one  center  located  in San  Diego,  California,  that  provides
evaluation and treatment for patients with  tinnitus.  The Company also operates
the Sonus Hearing Institute,  a state-of-the art hearing healthcare research and
training  facility,  adjacent to the  Company's  corporate  offices in Portland,
Oregon.

                                      -3-
<PAGE>

         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 instruments,
follow-up rehabilitative  assistance,  the sale of hearing instrument batteries,
hearing instrument  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  involves  expanding its  operations by
selectively  acquiring  hearing  centers  located  in  existing  as  well as new
geographic markets and by increasing the number of licensees under the Company's
franchise licensing program.  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 Company-owned
and  licensed  hearing care centers  devoted to providing  high-quality  hearing
health care services.

         The  Company  works to expand its network of  Company-owned  centers 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  then seeks to acquire
additional  individual or group practices in order to realize economies of scale
in management, marketing, and administration, in 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
centers.  From August 1, 1996, to September 30, 1999,  the Company  acquired 108
centers, all located in the United States.

         The Company looks at the following  factors before acquiring centers in
a particular  geographic  market:  (a)  population  size and  distribution;  (b)
audiology  practice  density,  saturation  and  average  group  size;  (c) local
competitors;  (d) level of managed care penetration;  and (e) local industry and
economy. In acquiring particular centers within a geographic market, the Company
seeks centers with the following  characteristics:  (a) an  established  patient
base drawing from a substantial metropolitan population; (b) significant revenue
and  profitability  prior to  acquisition;  and (c)  above-average  potential to
enhance center profitability after acquisition.

         Prior to acquiring a hearing care  center,  the Company  conducts a due
diligence  investigation of the center's  operations that includes an analytical
review of the center's financial  statements,  tax returns,  and other operating
data, a review of patient  files on a random  sample  basis,  a review of credit
reports,  contracts, bank deposits, and other documents and information that the
Company deems significant,  and the preparation of financial projections.  Based
on the information  collected and analyzed during the due diligence review,  the
Company determines an appropriate purchase price for the acquisition.

                                      -4-
<PAGE>

         The Company generally uses cash, promissory notes,  assumption of debt,
or a combination of the foregoing to fund acquisitions. 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, and patient files. At the
time a practice is acquired,  the audiologists and hearing instrument dispensers
associated with the practice typically become employees of the Company.

         There can be no assurance  that the Company will be able to continue to
complete  acquisitions  consistent  with its expansion  plans,  that such future
acquisitions will be on terms favorable to the Company, or that the Company will
be able to successfully integrate the hearing care centers that it acquires into
its business.  Successful  integration is dependent upon  maintaining  payor and
customer  relationships and converting the management information systems of the
centers the Company  acquires to the Company's  systems.  Significant  expansion
could place excessive strain on the Company's managerial and other resources and
could  necessitate  the  hiring  of  additional  managerial  and  administrative
personnel.  Unforeseen  problems with future  acquisitions  or failure to manage
expansion  effectively  may have a  material  adverse  effect  on the  business,
financial condition, and results of operations of the Company.

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 center 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.

Recruiting Qualified and Productive  Audiologists.  Audiologists employed by the
Company  are  primarily  responsible  for  center  profitability  as well as for
attracting and retaining customers. The Company seeks to employ audiologists who
share the Company's goal of delivering high-quality hearing care service and who
are also dedicated to expanding and enhancing their  practices.  The Company has
developed an intensive  four-week in-house training course called the Greenhouse
Program(R) for its  audiologists  that focuses on clinical  audiology  skills as
well as private  practice  business  management.  The Company  believes that the
Greenhouse  Program(R)  can  significantly  increase  employee  performance  and
improve  customer  service.   The  Company  also  believes  that  it  can  offer
significant benefits to private practice audiologists by providing assistance in
administrative  tasks associated with operating an audiology  practice,  thereby
allowing them to focus on serving patients and increasing productivity.

                                      -5-
<PAGE>

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 centers. When a center is acquired by
the Company, it immediately has available to it terms and discounts with hearing
instrument  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 center can be improved by spreading the cost of
such  functions over a larger revenue base. The Company has developed an on-line
management  information  system that links a substantial number of the Company's
centers with the Company's corporate headquarters in order to provide management
with the ability to collect and analyze center data,  control overhead expenses,
allow  detailed  budgeting at the center level,  and permit  effective  resource
management. All of the Company's centers are expected to be on-line by May 2000.

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
through its  Company-owned  centers and through its  licensees,  it will be well
positioned to offer services to group hearing care plans in that market. 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.  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.

         Many third-party 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  instrument  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.

CENTER STAFFING AND FACILITIES

         Typically,  each Company-owned  hearing center is staffed with at least
one audiologist  and one patient care  coordinator,  who handles  scheduling and
clerical  functions.  Where volume  warrants,  a center may also be staffed with
additional  audiologists,   hearing  instrument  dispensers,  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  instruments  and is a  member  of the  American
Speech-Language   Hearing   Association   or   the   Canadian   Association   of
Speech/Language Pathologists and Audiologists.

         Each of the  Company's  hearing  centers  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 center.  Centers  generally have a reception
seating area, a reception work and filing area, an office for the audiologist or
hearing  instrument  dispenser,  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 center
offering  advanced  audio-diagnostic  services  is much  greater and ranges from
$225,000 to $250,000.

PRODUCTS AND SUPPLIERS

         The hearing  instrument  manufacturing  industry is highly  competitive
with   approximately  40  manufacturers   serving  the  worldwide  market.   Few
manufacturers offer significant product  differentiation.  The Company currently
purchases  a large  percentage  of its  hearing  instruments  from  six  primary
manufacturers based upon criteria that include quality,  price, and service. The
Company recently began offering a line of private-label hearing instruments that
is being marketed as the Sonus Digital  Hearing  System.  In addition to hearing
instruments,  the  Company's  centers  also offer a limited  selection  of other
assistive listening devices and hearing instrument accessories.

MARKETING

         The  Company's  marketing  program is designed to help its hearing care
centers 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
centers for their future  hearing care needs.  Educating  patients about hearing
health,  prescribing only necessary  hearing enhancing  products,  ensuring that
each  patient  leaves  a center  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  center  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  instruments.
However,  the Company also competes with other  networks of hearing care centers
and with large  distributors  of hearing  instruments  such as Dahlberg,  Inc, a
hearing instrument manufacturer that distributes its products through a national
network of over 1,000 franchised and  company-owned  stores  (Miracle-Ear),  and
Beltone  Electronics Corp., a hearing  instrument  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.

REGULATION

         The sale of hearing  instrument  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 instruments 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  instruments  provide  customers  with certain  warning  statements  and
notices in connection  with the sale of hearing  instruments and that such sales
be made in compliance with certain labeling requirements.

         Most  states in the United  States and many  provinces  in Canada  have
established  formal  licensing  procedures  that  require the  certification  of
audiologists   and/or  HISs.   Although  the  extent  of  regulation  varies  by
jurisdiction, almost all states and provinces engage in some degree of oversight
of the  industry.  The Company  operates its hearing  care  centers  through its
wholly owned  subsidiaries,  Sonus-USA,  Sonus-Texas,  and  Sonus-Canada.  These
subsidiary  corporations  employ  licensed  audiologists  and HISs who offer and
perform  audiology  services and dispense  hearing  instruments on behalf of the
Company.

         In certain states in the United States,  business  corporations such as
Sonus-USA  may not be  authorized  to employ  audiologists  and offer  audiology
services.  For example,  in California,  where the Company  operates a number of
centers,   although  the  performance  of  audiology  services  by  professional
corporations owned solely by licensed audiologists is expressly authorized under
California  law, it is unclear  whether general  business  corporations  such as
Sonus-USA  may  employ  licensed  audiologists  to perform  audiology  services.
However,  the  California  Department  of  Consumer  Affairs  has  indicated  by
memorandum that speech-language pathologists, which are regulated under statutes
and  regulations  similar to those  governing  audiologists,  may  practice in a
general business corporation and that a general business corporation may provide
speech-language  pathology  services  through licensed speech  pathologists.  In
Illinois,  where the  Company  also  operates  a number of  centers,  it is also
unclear whether general business  corporations may employ licensed  audiologists
to  perform   audiology   services.   Under  Illinois  law,  only   professional
corporations  and  individuals  are  authorized  to obtain  licenses to practice
audiology.

                                      -8-
<PAGE>

         The laws and  regulations  governing  the  practice  of  audiology  are
enforced by regulatory agencies with broad discretion. If the Company were found
to be in  violation  of such laws and  regulations  in one or more  states,  the
consequences  could  include  the  imposition  of fines and  penalties  upon the
Company and its  audiologists as well as the issuance of orders  prohibiting the
Company from operating its centers under its present  structure.  In that event,
among the solutions the Company might consider would be the restructuring of all
or a portion  of its  operations  in a manner  similar  to that used by  certain
medical  and  dental  center  networks.  Under  such a  structure,  professional
corporations  owned by licensed  audiologists would contract with the Company to
perform   professional   services  and  the  Company  would  contract  with  the
professional corporations to provide management services.

         No assurance can be given that the Company's  activities  will be found
to be in compliance with laws and regulations  governing the corporate  practice
of audiology 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 portion of the revenues of the hearing  care centers  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.

         Because of its franchise  licensing  program,  The Sonus  Network,  the
Company is subject to state and federal regulation of franchising.  Much of this
regulation  involves providing detailed  disclosure to a prospective  franchisee
and periodic registration by the franchisor with state administrative  agencies.
Additionally, some states have enacted, and others have considered,  legislation
that governs the  termination or non-renewal of a franchise  agreement and other
aspects of the  franchise  relationship.  The United  States  Congress  has also
considered legislation of this nature. The Company believes that it has complied
with all applicable franchise laws and regulations.

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 instrument to
the Company and obtain a full refund up to 60 days (75 days for certain  models)
after  the  date of  purchase.  In  general,  the  Company  can  return  hearing
instruments  returned  by  customers  within  the return  period  allowed by the
Company to the manufacturer for a full refund.  The Company maintains an accrual
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 October 1, 1999,  the Company  had 269  full-time  and 89  part-time
employees,  of which  100 are  audiologists  or  hearing  instrument  dispensers
practicing  full time and 24 are  practicing  part-time.  None of the  Company's
employees are  represented  by a labor union.  Management  believes it maintains
good relationships with its employees.

SERVICE AND ENFORCEMENT OF LEGAL PROCESS

         The Company is incorporated under the laws of Yukon Territory,  Canada.
Two of the  Company's  directors 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 Company's securities
to effect  service  within the United  States upon those  directors  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.  There is doubt as to the
enforceability in Canada against the Company or against any of its directors 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.  The  Company's  agent for
service of process in the United States is MN Service Corp.  (Oregon),  111 S.W.
Fifth Avenue, Suite 3500, Portland, Oregon 97204, telephone (503) 224-5858.

ITEM 2. DESCRIPTION OF PROPERTY

         The Company's  executive  offices are located in  approximately  12,400
square feet of leased  office  space in  downtown  Portland,  Oregon.  The lease
expires on  September  30, 2004 and provides for an annual base rent of $235,200
until October 1, 2003, when the annual base rent increases to $273,060.  Each of
the Company's  hearing centers operates in leased space that ranges in size from
800 to 3,000 square feet.  Approximately  65 percent of the locations are leased
for one to eight-year  terms pursuant to generally  non-cancelable  leases (with
renewal options in some cases) with the remaining locations leased on a month-to
month basis. The aggregate committed rental expense as of July 31, 1999, for the
subsequent five-year period is approximately $5.7 million.

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

         Following is a summary of the  principal  Canadian  federal  income tax
considerations  under  the  Income  Tax Act  (Canada)  (the  "Tax  Act") and the
regulations  thereunder  generally  applicable to a holder of Common Shares who,
for purposes of the Tax Act, holds such shares as capital  property and deals at
arm's length with the Company. Generally, Common Shares will be considered to be
capital property to a holder provided the holder does not hold the Common Shares
in the course of carrying on a business of trading or dealing in securities  and
has not acquired them in one or more transactions  considered to be an adventure
in the nature of trade. Special rules apply to non-resident  insurers that carry
on an insurance business in Canada and elsewhere.

         This summary is based upon the provisions of the Tax Act in force as of
the date  hereof,  all  specific  proposals  to amend the Tax Act that have been
publicly announced prior to the date hereof (the "Proposed  Amendments") and the
Company's  understanding of the current published  administrative  and assessing
policies and practices of Revenue Canada, Customs, Excise and Taxation ("Revenue
Canada"). For the purposes of this summary, it has been assumed that the Tax Act
will be amended as proposed,  although no assurance can be given in this regard.
This summary is not exhaustive of all possible  federal income tax  consequences
and, except for the Proposed Amendments,  does not anticipate any changes in the
law, whether by legislative,  governmental or judicial  decision or action,  nor
does it take into account provincial, territorial or foreign tax considerations,
which may differ  significantly from those discussed herein. This summary is not
applicable to holders who are "specified financial institutions" for purposes of
the Tax Act, a holder that is a  "financial  institution"  as defined in the Tax
Act for  purposes  of the  mark-to-market  rules,  or to a holder of an interest
which would be a "tax shelter investment" as defined in the Tax Act.

                                      -11-
<PAGE>

         This summary is of a general nature only and is not intended to be, and
should not be  construed to be,  legal or tax advice to any  particular  holder.
Accordingly,  holders should consult their  independent  tax advisers for advice
with  respect  to the  income  tax  consequences  relevant  to their  particular
circumstances.

         The following  applies to holders of Common Shares who are not resident
in  Canada  for  purposes  of the Tax Act and who do not use or hold and are not
deemed to use or hold their Common Shares in, or in the course of, carrying on a
business in Canada.

Dispositions of Common Shares. A non-resident holder will, upon a disposition or
deemed disposition of Common Shares, not be subject to taxation in Canada on any
gain  realized  on the  disposition  unless  the shares  are  "taxable  Canadian
property"  for the  purposes of the Tax Act and no relief is  afforded  under an
applicable  tax  convention  between  Canada and the country of residence of the
holder.  Since the Common Shares are listed on a prescribed  stock  exchange for
the purposes of the Tax Act,  Common Shares held by a  non-resident  holder will
generally  not be "taxable  Canadian  property"  unless,  at any time during the
five-year period immediately preceding the disposition, the non-resident holder,
persons with whom the non-resident  holder did not deal at arm's length,  or the
non-resident  holder  together  with  such  persons,  owned or had the  right to
acquire  25% or more of the  issued  shares of any class of the  capital  of the
Company.  Any  interest  in shares  or  options  in  respect  of shares  will be
considered to be the  equivalent of ownership of such shares for purposes of the
definition of taxable Canadian property.

         Non-residents  whose shares constitute "taxable Canadian property" will
be subject to  taxation in respect of a  disposition  or deemed  disposition  of
Common Shares on the same basis as Canadian  residents unless otherwise exempted
by an applicable tax  convention  between Canada and the country of residence of
the holder.

         Pursuant to the Canada-United  States Income Tax Convention,  1980 (the
"Convention"),  shareholders  of the Company  that are  residents  in the United
States 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 disposition of the Common Shares,  provided the principal value
of the Company is not derived from real  property  located in Canada at the time
of disposition.

         Non-resident  holders  who might hold their  Common  Shares as "taxable
Canadian  property"  should  consult  their own tax advisers with respect to the
income tax consequences of a disposition of their Common Shares.

         Non-resident  holders  whose  shares are  repurchased  by the  Company,
except in respect of certain  purchases  made by the Company in the open market,
will be deemed to have  received  the payment of a dividend by the Company in an
amount equal to the excess paid over the paid-up capital of the Common Shares so
purchased.  Such deemed dividend will be excluded from the holder's  proceeds of
disposition  of the Common Shares for the purposes of computing any capital gain
or loss but will be  subject to  Canadian  non-resident  withholding  tax in the
manner described below under "Dividends."

Dividends.  Dividends received by a non-resident holder of Common Shares will be
subject to  Canadian  withholding  tax at the rate of 25% of the amount  thereof
unless the rate is reduced under the  provisions of an applicable tax convention
between Canada and the country of residence of the holder. The provisions of the
Convention generally reduce the rate to 15%. A further reduction to 5% under the
Convention  will be available if the  recipient is a company which owns at least
10% of the voting shares of the Company.

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.

         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.  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  Shares,  except as discussed
elsewhere herein.

SALES OF UNREGISTERED SECURITIES DURING FISCAL 1999

         There were no securities  of the Company  issued  without  registration
under the  Securities  Act of 1933 during the fiscal  year ended July 31,  1999,
except as previously  reported in the Company's quarterly reports on Form 10-QSB
filed during the fiscal year.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION



OVERVIEW

         During  the  fiscal  year ended July 31,  1999,  the  Company  achieved
significant  growth in revenues,  primarily due to the acquisition and operation
of additional hearing care centers. For the fiscal year ended July 31, 1999, the
Company  generated  total  revenues  of $33.8  million,  an increase of 51% over
fiscal 1998. For the fiscal year ended July 31, 1999, the Company incurred a net
loss of $4.9 million, compared to a net loss of $4.6 million for the 1998 fiscal
year. As of July 31, 1999,  the Company's  accumulated deficit was $11.6 million
and its total shareholders' equity was $18.8 million.

ACQUISITIONS

         During the fiscal year ended July 31,  1999,  the  Company  acquired 31
hearing care centers in 17  transactions.  The aggregate  purchase price for the
acquisitions  consisted of cash payments of $1,704,000,  promissory notes issued
by the Company of $1,749,000 generally payable over three years, and $900,000 in
assumed  liabilities.  As a result of the  acquisitions,  the  Company  recorded
approximately $95,000 in accounts receivable,  $90,000 in inventory, $457,000 in
property and  equipment,  $20,000 in other assets,  and  $3,700,000 in goodwill,
which included costs related to acquisitions. The Company also recorded $299,000
for covenants  not to compete,  of which $79,000 was paid in cash at the time of
closing, with the balance payable over three years.

         The 31 hearing  care  businesses  acquired  by the  Company  during the
fiscal year ended July 31, 1999,  have  combined  historical  revenues for their
immediately  preceding fiscal years of approximately  $8.6 million.  The Company
expects these centers to contribute to the Company's future revenues  consistent
with their  historical  revenues,  as well as to have a positive  effect on cash
flows and liquidity.

         As of July 31, 1999,  the Company had recorded  $19,774,000 in goodwill
and $2,226,000 in covenants not to compete.  The amortization of the unamortized
balance totaling  $19,768,000 at July 31, 1999, which represented  approximately
63% of the Company's  total assets,  will result in an annual non-cash charge to
earnings of  approximately  $948,000 in each of the next 20 years. If all of the
employees  with  covenants  not to compete  referred  to above were to leave the
Company, an additional non-cash charge to earnings of approximately  $677,000 in
each of the current and next two fiscal years would also be incurred.

RESULTS OF OPERATIONS

Year Ended July 31, 1999, Compared to Year Ended July 31, 1998

         Revenues.  Total revenues for the fiscal year ended July 31, 1999, were
$33,759,000,  representing a 51% increase over revenues of  $22,368,000  for the
prior fiscal year. The increase was primarily due to the 31 businesses  acquired
during fiscal 1999.  Revenue was also favorably impacted by an increase of 5% in
comparable center revenue in fiscal 1999.  Comparable  centers are those centers
that have been open at least 24 months.  Product sales revenues were $29,044,000
for the  1999  fiscal  year,  up 55%  from  the  $18,792,000  for  fiscal  1998.
Audiological  service  revenues  increased  from  $3,311,000,  or 15%  of  total
revenues, in fiscal 1998, to $3,392,000,  or 10% of total revenues, for the 1999
fiscal year.

         Gross Profit on Product Sales. Product gross profit for the fiscal year
ended July 31,  1999,  was  $18,278,000  compared to  $11,080,000  for the prior
fiscal  year.  Gross profit  percentage  on product  sales  increased to 63% for
fiscal 1999 from 59% for fiscal 1998. The increase in gross profit percentage on
product sales was primarily  attributable to increased buying power with hearing
instrument  manufacturers,  less  dependence  on sales  discounts,  better price
management and a new tiered pricing strategy based on levels of technology.

         Clinical  Expenses.  As a  percentage  of revenues,  clinical  expenses
decreased  to 53% for the fiscal year ended July 31,  1999,  compared to 55% for
the fiscal year ended July 31,  1998.  The  percentage  decrease  was due to the
Company's  ability  to cut  costs,  streamline  its  operations,  and  eliminate
inefficient and  duplicative  processes.  Clinical  expenses for the fiscal year
ended July 31,  1999,  were  $17,795,000,  representing  an increase of 45% over
clinical  expenses of $12,297,000  for the prior fiscal year.  This increase was
primarily due to clinical expenses associated with the 31 additional  businesses
that were  acquired by the Company  during the fiscal year ended July 31,  1999.
Clinical  expenses  include  all  personnel,   marketing,  occupancy  and  other
operating expenses at the center level.

         General and  Administrative  Expenses.  As a  percentage  of  revenues,
general and  administrative  expenses decreased to 22% for the fiscal year ended
July 31,  1999,  versus 26% for the same period in the prior  fiscal  year.  The
decrease in general and administrative  expenses as a percentage of revenues was
due to  growth  in the  Company's  revenue  base as a  result  of its  strategic
acquisition program and enhanced marketing efforts, as well as an administrative
restructuring  and  cost-cutting  program  implemented  by the Company in fiscal
1999.  General and  administrative  expenses in dollar terms  increased 29% from
$5,896,000 for the fiscal year ended July 31, 1998, to $7,583,000 for the fiscal
year ended July 31, 1999, due to planned  increases in corporate staff and other
corporate expenses related to the operation of a larger organization.

         Depreciation  and Amortization  Expense.  Depreciation and amortization
expense for the fiscal year ended July 31, 1999, was $2,450,000,  an increase of
80% over the depreciation  and amortization  expense of $1,361,000 for the prior
fiscal  year.  The  increase  resulted  from the  depreciation  of property  and
equipment and  amortization of goodwill and covenants not to compete  associated
with the 31 additional businesses acquired by the Company during the fiscal year
ended July 31, 1999, as well as from  depreciation and  amortization  associated
with businesses acquired in the second half of fiscal 1998.

         Interest Income and Expense.  Interest income for the fiscal year ended
July 31, 1999,  decreased to $261,000  from  $452,000 for the prior fiscal year.
The decrease was due to lower balances of cash and short-term  investments  held
by the Company.  Interest  expense for the fiscal year ended July 31, 1999,  was
$300,000  compared to $149,000 for the fiscal year ended July 31,  1998,  due to
higher balances of long-term debt incurred in connection with acquisitions.

         Net Loss.  For the fiscal year ended July 31,  1999,  the Company had a
net loss of $4,884,000  compared to a net loss of $4,594,000 for the fiscal year
ended July 31, 1998. The Company's loss from operations before  depreciation and
amortization for fiscal 1999 was $2,385,000 compared to an operating loss before
depreciation and amortization of $3,537,000 for fiscal 1998.

Year Ended July 31, 1998, Compared to Year Ended July 31, 1997

         Revenues.  Total revenues for the fiscal year ended July 31, 1998, were
$22,368,000,  representing a 66% increase over revenues of  $13,462,000  for the
prior fiscal year.  Of this  increase,  $3,760,000  was  attributable  to the 34
businesses  acquired during fiscal 1998. Product sales revenues were $18,792,000
for the  1998  fiscal  year,  up 64%  from  the  $11,472,000  for  fiscal  1997.
Audiological  service  revenues  increased  from  $1,943,000,  or 14%  of  total
revenues in fiscal 1997, to $3,311,000,  or 15% of total revenues,  for the 1998
fiscal year.

         Gross Profit on Product Sales. Product gross profit for the fiscal year
ended July 31, 1998, was $11,080,000 compared to $6,462,000 for the prior fiscal
year.  Gross profit  percentage  on product sales was 59% for fiscal 1998 versus
56% for fiscal 1997.  The increase in gross profit  percentage  on product sales
was primarily  attributable to higher volume  discounts,  improved product sales
management, and an increase in the percentage of total revenues derived from the
Company's  operations in the United States,  where gross profit  percentages are
higher than those for the Company's operations in Canada.

         Clinical Expenses. Clinical expenses for the fiscal year ended July 31,
1998, were $12,297,000,  representing an increase of 105% over clinical expenses
of  $5,985,000  for the prior fiscal year.  This  increase was  primarily due to
clinical expenses  associated with the 34 additional  businesses that were owned
by the Company  during the fiscal year ended July 31, 1998, but not owned during
the prior fiscal year,  and increased  marketing  expenses  designed to increase
brand awareness of the Company within the hearing health industry.

         General  and  Administrative   Expenses.   General  and  administrative
expenses  increased 73% from $3,410,000 for the fiscal year ended July 31, 1997,
to $5,896,000 for the fiscal year ended July 31, 1998, due to planned  increases
in corporate  staff and other corporate  expenses  related to the operation of a
larger  organization,  as well as one-time  expenses incurred in connection with
the implementation of the Company's franchise and branding programs,  consulting
and professional fees, and inventory revaluations.  As a percentage of revenues,
general and  administrative  expenses rose to 26% for the fiscal year ended July
31, 1998, versus 25% for the prior fiscal year.

                                      -15-
<PAGE>

         Depreciation  and Amortization  Expense.  Depreciation and amortization
expense for the fiscal year ended July 31, 1998, was $1,361,000,  an increase of
72% over the  depreciation  and  amortization  expense of $790,000 for the prior
fiscal  year.  The  increase  resulted  from the  depreciation  of property  and
equipment and  amortization of goodwill and covenants not to compete  associated
with the 34 additional businesses operated by the Company during the fiscal year
ended July 31, 1998.

         Interest Income and Expense.  Interest income for the fiscal year ended
July 31, 1998, increased to $452,000 from $76,000 for the prior fiscal year. The
increase was due to higher balances of cash and short-term  investments  held by
the Company as a result of a sale of preferred  shares in December  1997 and the
exercise  of  warrants to purchase  Common  Shares in  February  1998.  Interest
expense  for the fiscal  year ended July 31,  1998,  was  $149,000  compared  to
$47,000  for the fiscal  year ended July 31,  1997,  due to higher  balances  of
long-term debt incurred in connection with acquisitions.

         Net Loss.  For the fiscal year ended July 31,  1998,  the Company had a
net loss of $4,594,000  compared to a net loss of $1,701,000 for the fiscal year
ended July 31, 1997. The Company's loss from operations before  depreciation and
amortization  for fiscal 1998 was $3,537,000  compared to a loss of $943,000 for
fiscal 1997.

LIQUIDITY AND CASH RESERVES

         For the fiscal  year ended July 31,  1999,  net cash used in  operating
activities  was  $2,281,000  compared to $2,203,000 for fiscal 1998 and $606,000
for fiscal  1997.  Net cash  provided by  investing  activities  was $878,000 in
fiscal 1999 compared to net cash used in investing  activities of $11,786,000 in
fiscal  1998  and  $4,021,000  in  fiscal  1997.  The  Company  sold  short-term
investments to fund  acquisitions and provide working capital during fiscal 1999
in contrast to its purchase of short-term  investments in fiscal 1998 and fiscal
1997  following the sale of preferred  shares in the second quarter and the sale
of common  shares and  warrants in fiscal 1997.  Net cash  provided by financing
activities was $5,742,000 in fiscal 1997 and $15,817,000 in fiscal 1998 compared
to net cash used in financing  activities of $821,000 in fiscal 1999. The change
was  primarily  the result of funds  provided  by the sale of common  shares and
warrants in fiscal 1997 and the sale of preferred shares in fiscal 1998.

         On October 1, 1999, the Company issued  2,500,000  Series B Convertible
Preferred  Shares in a private  placement for  $10,000,000 in cash. As a result,
the Company believes that its cash and short-term  investments,  along with cash
generated from operations,  will provide it with sufficient  capital to fund its
operations over the next 12 months.  Thereafter,  the Company  anticipates  that
additional  funding will be needed to fund the  Company's  strategy of acquiring
additional  hearing care centers.  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.
Any such  issuance of equity may be dilutive  to current  shareholders  and debt
financing may impose significant restrictive covenants on the Company. 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.

YEAR 2000

         The "Year 2000  problem"  refers to the  possibility  that computer and
other systems could fail or not work properly as a result of these systems using
only the last two  digits  of a year to refer to that year and  therefore  being
unable to properly  recognize a year that begins with "20" instead of "19".  The
Company  has  undertaken  a review  of the  potential  effects  of the Year 2000
problem on its business on a system by system basis.

                                      -16-
<PAGE>

         With respect to its information  technology ("IT") systems, the Company
believes  that the  computer  hardware  and  system  software  of its IBM AS/400
computer,  on which its patient management system and accounting system operate,
are  Year  2000  compliant.  Unrelated  to Year  2000  issues,  the  Company  is
continuing its development of a new patient  management system.  Initially,  the
Company's  hearing care centers and its  subsidiary  Hear PO Corp.  will use the
software.  However,  in the future the Company  may license the  software to its
Sonus Network franchise licensees and others. The development contractor for the
software has represented  that it will meet Year 2000 standards.  Implementation
of the new software is expected to begin in November 1999. The Company installed
a new release of its accounting and financial  reporting software in March 1999,
which the vendor represents is Year 2000 compliant. The Company has surveyed all
of its servers, personal computers, and network hardware to determine compliance
with Year 2000  standards and is in the process of replacing all equipment  that
was found to be deficient.  The Company  estimates that the  replacement of this
equipment  will be completed  before  December  31,  1999,  and that the cost of
replacement will be less than $50,000.

         The  Company  has  reviewed  its  non-IT   systems   (primarily   voice
communications)  for Year 2000  compliance  and has replaced  those systems that
were found to be non-compliant. The Company's cost to replace the non-IT systems
that were non-compliant with Year 2000 standards was less than $50,000.

         The  Company  also faces the risk that  vendors  from which the Company
purchases goods and services, such as hearing instrument manufacturers,  utility
providers, the banks that maintain the Company's depository accounts and process
its credit card  transactions,  and the Company's  payroll  processor,  may have
systems  that  are not  Year  2000  compliant.  Significant  disruptions  in the
operations of its vendors may have a material adverse effect on the Company. The
Company is  continuing to monitor the progress of its major vendors in achieving
Year 2000  compliance.  However,  the Company  presently does not anticipate the
occurrence of major interruptions in its business due to Year 2000 issues.

         The Company has not established a contingency plan to address potential
Year 2000  noncompliance  with respect to the Company's  systems or those of its
major vendors and is  considering  the extent to which such a plan is necessary.
Due to the  Company's  dependence  on  systems  outside  its  control,  such  as
telecommunications,   transportation,  and  power  supplies,  there  can  be  no
assurance that the Company will not face unexpected problems associated with the
Year 2000  problem  that may  affect its  operations,  business,  and  financial
condition.

ACCOUNTING PRONOUNCEMENTS

         In June 1998,  Statement of  Financial  Accounting  Standards  No. 133,
"Accounting for Derivative  Instruments and Hedging Activities" ("SFAS No. 133")
was issued. SFAS No. 133 standardizes the accounting for derivative  instruments
by requiring  that an entity  recognize  those items as assets or liabilities in
the  financial  statements  and  measure  them at fair  value.  SFAS No.  133 is
effective for all fiscal  quarters of all fiscal years  beginning after June 15,
2000. As the Company does not hold any derivative  instruments,  SFAS No. 133 is
not expected to have an impact on the Company's financial statements.

         In April 1998, the American  Institute of Certified Public  Accountants
issued  Statement  of  Position  98-5,  "Reporting  on  the  Costs  of  Start-Up
Activities"  ("SOP 98-5") which  requires that costs of start-up  activities and
organizational  costs  be  expensed  as  incurred.  SOP  98-5 is  effective  for
financial  statements  for fiscal  years  beginning  after  December  15,  1998.
Although the Company has not fully determined its complete  impact,  the Company
does  not  foresee  any  material  change  due to  adoption  of SOP  98-5 on its
financial statements.

standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting

management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material respects,  the consolidated  financial position of Sonus
Corp.  and  subsidiaries  as of July 31,  1999 and  1998,  and the  consolidated

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                             JULY 31, 1999 AND 1998


NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Description of Company
         ----------------------

         Sonus Corp., a Yukon  Territory,  Canada  corporation  (the "Company"),
through  its  primary  operating  subsidiaries,  Sonus-Canada  Ltd.,  a  British
Columbia,  Canada corporation,  Sonus-USA,  Inc., a Washington corporation,  and
Sonus-Texas,  Inc.,  an Oregon  corporation,  owns and  operates 99 hearing care
centers in the United States and Western Canada.  The centers are located in the
states of Arizona, California, Illinois, Michigan, Missouri, New Mexico, Oregon,
Texas,  and Washington,  and in the Canadian  provinces of British  Columbia and
Alberta.  Each of the  Company's  hearing  care  centers  provides  its  hearing
impaired patients with a full range of audiological  products and services.  The
Company  intends to expand its  network of  hearing  care  centers by  acquiring
centers in its existing,  as well as new, geographic  markets.  The Company also
operates a franchise  licensing program called The Sonus Network.  Licensees are
entitled  to use the Sonus name and  receive  other  benefits  such as  practice
management advice and training,  group buying discounts, and marketing services.
The Company,  through its subsidiary  Hear PO Corp.,  a New Mexico  corporation,
also operates as an independent  provider  association  and hearing care benefit
administrator.  Hear PO Corp. obtains contracts to provide hearing care benefits
to managed  care group and  corporate  health  care  organizations  through  its
approximately 1,100 affiliated  audiologists,  sells Hear PO brand private label
hearing  instruments,  and  operates  as  a  buying  group  for  its  affiliated
audiologists.

         Principles of Consolidation
         ---------------------------

         The  consolidated  financial  statements  include the Company's  wholly
owned subsidiaries. All significant inter-company accounts have been eliminated.
The  functional  currency of the Company's  Canadian  operations is the Canadian
dollar while the  functional  currency of the Company's  U.S.  operations is the
U.S.  dollar.  In accordance  with Statement of Financial  Accounting  Standards
("SFAS") No. 52, "Foreign Currency Translation", assets and liabilities recorded
in Canadian  dollars are remeasured at current rates in existence at the balance
sheet date.  Revenues  and expenses are  remeasured  using the weighted  average
exchange rate for the period.  Exchange gains and losses from  remeasurement  of
assets and  liabilities  recorded in Canadian  dollars are treated as unrealized
gains and losses and reported as a separate component of shareholders' equity.

         Revenue Recognition
         -------------------

Revenues from the sale of hearing instrument 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.


                                      -23-

         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. A valuation  allowance is
established  when necessary to reduce deferred tax assets to the amount expected
to be realized.

         Cash and Cash Equivalents
         -------------------------

         Cash equivalents consist of short-term,  highly liquid investments with
original maturities of 90 days or less.

         Short-term Investments
         ----------------------

         Short-term  investments consist of  available-for-sale  securities,  as
defined by SFAS No. 115,  "Accounting for Certain Investments in Debt and Equity
Securities".  Under  SFAS No.  115,  unrealized  holding  gains and  losses  are
reflected as a net amount in a separate component of shareholders'  equity until
realized.  At July 31,  1999,  the Company  had no  short-term  investments  and
therefore no unrealized holding gains or losses. At July 31, 1998, there were no
unrealized  holding  gains  or  losses  as the  market  value  of the  Company's
available-for-sale securities approximated cost. Gross realized gains and losses
on sales of  available-for-sale  securities for fiscal 1999, 1998, and 1997 were
nominal.  Realized  gains and  losses  are  computed  by  determining  cost on a
specific identification basis.

         At July 31, 1998, the Company's short-term investments consisted of the
following debt securities  which had maturities of less than six months and were
carried at cost which approximated market (in thousands):

             Corporate Bonds                    $2,760

             Discount Commercial Paper           3,648
                                                ------
                                                $6,408
                                                ======

         Gross  proceeds  from  sales  and   maturities  of   available-for-sale
investments  during  fiscal  1999  and 1998  were  $6,408,000  and  $18,511,000,
respectively.

         Inventory
         ---------

         Inventory primarily consists of hearing instruments, hearing instrument
batteries,  and assistive  listening  devices and is stated at the lower of cost
(first in, first out) or net realizable value.

                                      -24-
<PAGE>

         Property and Equipment
         ----------------------

         Property and equipment are recorded at cost and  depreciated  using the
straight-line method over the following useful lives:

         Professional equipment                                   Seven years
         Office equipment                                         Five years
         Leasehold improvements                                   Five years
         Computer equipment and software                          Five years

         Property and equipment purchased under capitalized leases are amortized
over the  shorter of the lease  term or their  estimated  useful  lives and such
depreciation  is included with  depreciation  expense.  On November 1, 1997, the
Company  changed the method by which it calculates  depreciation on property and
equipment to the straight-line method.  Previously,  professional  equipment was
depreciated  using the 20%  declining  balance  method and  office and  computer
equipment and  automobiles  were  depreciated  using the 30%  declining  balance
method.  The Company also adopted a useful life of seven years for  professional
equipment  and five years for office  equipment.  The  cumulative  effect of the
changes  adopted by the Company for the fiscal year ended July 31, 1998, was not
significant.

         Advertising Expense
         -------------------

         The Company defers its  advertising  costs until the  advertisement  is
actually run, at which time the full expense is recognized. Deferred advertising
costs were $84,000 and $0 at July 31, 1999 and 1998,  respectively.  Advertising
expense was  $3,632,000,  $2,786,000  and  $786,000 for the years ended July 31,
1999, 1998, and 1997, respectively.

         Goodwill and Covenants Not to Compete
         -------------------------------------

         The  unallocated  purchase  costs in excess of the net assets  acquired
(goodwill)  is being  amortized on the  straight-line  basis over twenty  years.
Non-compete  agreements are amortized on the straight-line basis over the period
benefited. Goodwill and covenants not to compete are as follows as of July 31:

         (in thousands)                                 1999              1998
                                                        ----              ----
         Goodwill                                     $19,774           $15,611

         Covenants not to compete                       2,226             1,578

         Less:  Accumulated amortization               (2,232)           (1,037)
                                                       ------            ------

                                                      $19,768           $16,152
                                                      =======           =======

         Amortization  charged  to  operations  was  $1,195,000,   $635,000  and
$364,000 for the years ended July 31, 1999, 1998 and 1997, respectively.

                                      -25-
<PAGE>

         Deferred Acquisition and Financing Costs
         ----------------------------------------

         Costs  related to the  acquisition  of centers are deferred  and,  upon
successful completion of acquisitions,  are allocated to the assets acquired and
are  subject  to the  accounting  policies  outlined  above.  Costs  related  to
potential  acquisitions  that are  unsuccessful  are  expensed in the periods in
which it is determined  that such  acquisitions  are unlikely to be consummated.
Costs  related  to issuing  shares are  deferred  and upon the  issuance  of the
related shares, are applied to reduce the net proceeds of the issue.

         Impairment of Long-Lived Assets
         -------------------------------

         The Company assesses the recoverability of long-lived assets, including
goodwill,  by determining  whether the carrying  amount of the long-lived  asset
over its remaining live can be recovered through  undiscounted  projected future
cash flows.  The Company has not  recognized  any  impairment  losses during the
years ended July 31, 1999, 1998, and 1997.

         Net Loss Per Share
         ------------------

         On August 1, 1997,  the Company  adopted  SFAS No. 128,  "Earnings  Per
Share", which provides that "basic net income (loss) per share" and "diluted net
income  (loss)  per share"  for all  periods  presented  be  computed  using the
weighted  average  number of common  shares  outstanding  during the  respective
period,  with diluted net income per share  including the effect of  potentially
dilutive common shares.  Common stock  equivalents  related to convertible debt,
convertible  preferred stock, stock options, and warrants are anti-dilutive and,
therefore,  not included in the 1999, 1998, and 1997 diluted net loss per share.
Furthermore,  there were no reconciling  items to obtain net loss  applicable to
common  shareholders  from the  Company's  net loss for the years ended July 31,
1999, 1998, and 1997.

         Comprehensive Income (Loss)
         ---------------------------

         On August  1,  1998,  the  Company  adopted  SFAS No.  130,  "Reporting
Comprehensive  Income".  SFAS No. 130  establishes  standards  for reporting and
presentation  of  comprehensive  income  and  its  components  in a full  set of
financial statements.  Comprehensive income (loss) consists of net income (loss)
and foreign currency translation adjustment and is presented in the consolidated
statement  of  shareholders'  equity.  SFAS No.  130  requires  only  additional
disclosures in the  consolidated  financial  statements;  it does not affect the
Company's  financial  position or results of  operations.  Prior year  financial
statements  have been  reclassified  to conform to the  requirements of SFAS No.
130.

         Stock Based Compensation
         ------------------------

         The Company  accounts for its stock plans in  accordance  with SFAS No.
123, "Accounting for Stock-Based  Compensation",  which establishes a fair value
method of  accounting  for stock plans.  As allowed by SFAS No. 123, the Company
has elected to continue to apply Accounting Principles Board Opinion ("APB") No.
25,  "Accounting for Stock Issued to Employees",  which  prescribes an intrinsic
value based  method of  accounting  for stock plans  covering  employees  and to
provide the pro-forma  disclosures  of the effects of SFAS No. 123 on net income
(loss) and net income (loss) per share.

                                      -26-
<PAGE>

         Concentrations of Credit Risk
         -----------------------------

         Financial  instruments,   which  potentially  subject  the  Company  to
concentration  of  credit  risk,   consist   principally  of  cash,   short-term
investments, and trade receivables. The Company places its cash with high credit
quality  institutions.  At times,  such  amounts may be in excess of the Federal
Deposit Insurance  Corporation  insurance  limits.  The Company's trade accounts
receivable are derived from numerous private payers, 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 payers.

         Fair Value of Financial Instruments
         -----------------------------------

         The  carrying  value  of  financial  instruments  such as cash and cash
equivalents,  short-term  investments,  accounts receivable,  other receivables,
trade payables,  notes payable,  and convertible notes payable approximate their
fair value because of the short-term nature of these  instruments.  The carrying
amount of the  Company's  long-term  debt  approximates  fair value  because the
interest  rates  approximate  the rates that  management  believes are currently
available  to the  Company.  The carrying  amount of capital  lease  obligations
approximates fair value.

         Use of Estimates
         ----------------

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect the reported  amounts of assets and liabilities and the
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

         Reclassifications
         -----------------

         Certain  amounts in the 1997 and 1998  financial  statements  have been
reclassified to conform with the 1999 presentation.

NOTE 2.  ACQUISITIONS

         During the fiscal year ended July 31,  1999,  the  Company  acquired 31
hearing care centers in 17 transactions. Each transaction was accounted for as a
purchase.  The acquired assets and liabilities  were recorded at their estimated
fair values at the date of  acquisition,  and the  unallocated  excess  purchase
price  (goodwill) is being amortized on a straight line basis over 20 years. The
operating  results of each  acquisition  have been included in the  consolidated
statements of operations  from the  respective  acquisition  date. The aggregate
purchase  price for the  acquisitions  consisted of cash payments of $1,704,000,
promissory  notes  issued by the Company of  $1,749,000  generally  payable over
three  years,  and  $900,000  in  assumed  liabilities.   As  a  result  of  the
acquisitions, the Company recorded approximately $95,000 in accounts receivable,
$90,000 in  inventory,  $457,000 in  property  and  equipment,  $20,000 in other
assets,   and   $3,700,000  in  goodwill,   which   included  costs  related  to
acquisitions.  In  addition  to the  purchase  price for the  acquisitions,  the
Company also recorded  $299,000 for  covenants not to compete,  of which $79,000
was paid in cash at the time of  closing,  with the balance  payable  over three
years.

                                      -27-
<PAGE>

         During the fiscal year ended July 31,  1998,  the  Company  acquired 33
centers and one hearing  care benefit  administrator  in 18  transactions.  Each
transaction was accounted for as a purchase. The acquired assets and liabilities
were recorded at their estimated fair values at the date of acquisition, and the
unallocated  excess  purchase price  (goodwill) is being amortized on a straight
line basis over 20 years.  The operating  results of each  acquisition have been
included  in the  consolidated  statements  of  operations  from the  respective
acquisition date. The aggregate purchase price for the acquisitions consisted of
cash  payments  of  $3,650,000,  promissory  notes  issued  by  the  Company  of
$1,781,000  generally  payable  over  three  years,  and  $3,072,000  in assumed
liabilities. In addition,  $1,405,000 will be paid and 22,936 Common Shares that
have been  issued  but are being held by the  Company  will be  released  over a
three-year  period if certain annual net revenue targets are met. As a result of
the  acquisitions,  the Company  recorded  approximately  $1,186,000 in accounts
receivable,  $137,000 in inventory,  $629,000 in property and equipment, $96,000
in other assets,  and  $6,455,000 in goodwill,  which  included costs related to
acquisitions.  In  addition  to the  purchase  price for the  acquisitions,  the
Company also recorded  $623,000 for covenants not to compete,  of which $157,000
was paid in cash at the time of  closing,  with the balance  payable  over three
years.

         The following  unaudited pro forma financial  information  reflects the
historical operations of the hearing care centers acquired by the Company during
the fiscal year ended July 31, 1999 (the  "Acquisitions"),  from August 1, 1998,
to the date of  acquisition.  Such financial  information  has been prepared for
comparative  purposes  only and is not  necessarily  indicative of the Company's
combined  financial  position or the results of operations  that actually  would
have occurred if the  Acquisitions  had been  consummated on August 1, 1997, for
the fiscal  year ended July 31,  1998,  and August 1, 1998,  for the fiscal year
ended July 31,  1999.  In  addition,  such  information  is not intended to be a

NOTE 7.  SHAREHOLDERS' EQUITY

         Series A Convertible Preferred Shares

         In December 1997, the Company  issued  13,333,333  Series A Convertible
Preferred Shares (the "Series A Shares") in a private  placement.  The following
summarizes certain terms of the Series A Shares:

         Voting  Rights.  Each Series A Share is entitled to one-fifth of a vote
(or such other  number of votes equal to the number of Common  Shares into which
such Series A Share shall be  convertible  from time to time) in the election of
directors and any other matters presented to the shareholders of the Company for
action or consideration.

         Dividends.  Each Series A Share is entitled to receive, when, as and if
declared by the board of  directors of the Company out of the  Company's  assets
legally  available for payment,  cumulative  dividends from the date of original
issuance,  payable  annually at a rate of 5% per annum on a base amount of $1.35
per share  (the  "Base  Amount").  As of July 31,  1999,  cumulative  undeclared
dividends amounted to approximately $1,425,000. All accrued and unpaid dividends
will be forfeited upon the conversion of the Series A Shares.  The dividend rate
is subject to increase on specified  dates in the event that certain  conditions
(the "Triggering  Conditions") have not been met. The Triggering  Conditions are
as follows:

     (a) The  Common  Shares  are  listed on the New York  Stock  Exchange,  the
American Stock Exchange,  or the Nasdaq National Market (each a "U.S.  Principal
Market");

     (b) The  Common  Shares are  traded on a U.S.  Principal  Market at a daily
closing  price  greater  than  $12.00  per  Common  Share  on  each  of the  ten
consecutive trading days preceding the applicable date; and

     (c) The Company's net income before income taxes, dividends on the Series A
Shares,  and amortization of goodwill and covenants not to compete for the three
consecutive fiscal quarters preceding the applicable date shall have averaged at
least $.35 per fully  diluted  Common Share per fiscal  quarter (for purposes of
making  this  calculation,  the Common  Shares  issuable  upon the  exercise  of
warrants issued in connection with the Series A Shares will not be counted).

         If the Triggering Conditions have not been met by:

         (x) January 1, 2003, the dividend rate will thereafter be 15% per annum
of the Base Amount;

         (y) January 1, 2004, the dividend rate will thereafter be 18% per annum
of the Base Amount; or

         (z) January 1, 2005, the dividend rate will thereafter be 21% per annum
of the Base Amount.

         As soon as the Triggering Conditions have been satisfied,  the dividend
rate will revert to 5% per annum of the Base Amount.

                                      -30-

         Liquidation  Preference.  In the event of any voluntary or  involuntary
liquidation,  dissolution, or winding up of the Company subject to the rights of
holders of any  securities of the Company  ranking senior to the Series A Shares
upon  liquidation,  the  holders of Series A Shares will be entitled to receive,
out of the assets of the Company  available for  distribution  to  shareholders,
before any  distribution  of assets is made to  holders of Common  Shares or any
other  securities  ranking  junior to the Series A Shares  upon  liquidation,  a
liquidating  distribution  in an amount  equal to the  greater  of (i) $1.35 per
share plus any accrued and unpaid  dividends  or (ii) the amount that would have
been  distributable  to such holders if they had converted their Series A Shares
into  Common  Shares  immediately  prior to such  dissolution,  liquidation,  or
winding  up,  plus any  accrued  and  unpaid  dividends.  The sale,  conveyance,
mortgage,  pledge or lease of all or substantially all the assets of the Company
will  be  deemed  to be a  liquidation  of  the  Company  for  purposes  of  the
liquidation rights of the holders of Series A Shares.  After payment of the full
amount of the liquidating  distribution to which they are entitled,  the holders
of  Series A Shares  will  have no right to any of the  remaining  assets of the
Company.

         Optional  Redemption.  The Series A Shares may not be  redeemed  before
December 24, 2002. Thereafter, the Series A Shares may be redeemed at the option
of the  Company,  in whole or in part.  The  redemption  price will be an amount
equal to the  greater  of (i)  $1.35  per  share  plus any  accrued  and  unpaid
dividends or (ii) the fair market value of a Series A Share as  determined  by a
nationally  recognized  independent  investment  banking firm selected by mutual
agreement of the Company and the holder of a majority of the outstanding  Series
A Shares.  The Series A Shares are not subject to  mandatory  redemption  or any
sinking fund provisions.

         Conversion Rights. The Series A Shares may be converted at any time, in
whole or in part, at the option of the holder thereof,  into Common Shares.  The
conversion  rate is presently  equal to one Common Share for every five Series A
Shares  surrendered  for  conversion.  The conversion rate is subject to further
adjustment  for stock  dividends,  stock  splits,  recapitalizations,  and other
anti-dilution  adjustments.  Upon the  conversion  of any  Series A Shares,  any
accrued and unpaid dividends with respect to such shares will be forfeited.  The
Company has the right to force conversion of the Series A Shares, in whole or in
part, upon satisfaction of certain conditions.

         Release of Escrowed Shares
         --------------------------

         Effective  with the listing of the Common Shares on the American  Stock
Exchange on February 10, 1998, 850,000 common shares owned by certain members of
the  Company's  management  were  released  from  escrow  by The  Alberta  Stock
Exchange.  The  shares,  which had been  excluded  from the  calculation  of the
average  shares  outstanding  during the fiscal  year ended July 31,  1997,  are
included in such calculation for the fiscal years ended July 31, 1998 and 1999.

         Share Purchase Warrants
         -----------------------

     At July 31,  1999,  the Company had  outstanding  share  purchase  warrants
issued in  connection  with the  Series A Shares to  purchase  2,000,000  Common
Shares at an exercise  price of $12.00 per share until  December 24,  2002.  The
terms of the share  purchase  warrants  were  amended on  October  1,  1999,  in
connection  with the issuance of the Company's  Series B  Convertible  Preferred
Shares to reduce the exercise price to $6.75 per share and extend the expiration
date to October 1, 2004. The Company may force the exercise of the warrants upon
satisfaction of all the Triggering Conditions, except that the Common Shares are
only required to be traded on a U.S.  Principal  Market at a daily closing price
greater  than  $8.00  instead  of  $12.00  per  Common  Share on each of the ten
consecutive trading days preceding the applicable date.

                                      -31-
<PAGE>

     In August 1998,  the Company issued 39,799 Common Shares at $6.25 per share
in connection  with the exercise of share purchase  warrants issued in September
and December 1996. In February 1998, the Company issued 373,998 Common Shares at
$5.23 per share  pursuant to the exercise of share purchase  warrants  issued by
the Company in February 1996.

         Stock Option Plans
         ------------------

         The Company has two stock  option  plans,  the Stock Option Plan ("1993
Plan") and the Second Amended and Restated  Stock Award Plan ("1996 Plan").  The
Company may grant to officers,  directors,  employees and consultants  incentive
and  non-qualified  options to purchase up to 2,300,000  Common Shares under the
1996 Plan. There are options to purchase 245,000 Common Shares outstanding under
the 1993 Plan;  no further  options  will be  granted  under the 1993 Plan.  The
exercise  price of options  granted under the 1996 Plan may not be less than 75%
of the fair market  value of the  Company's  Common  Shares at the date of grant
(100% for tax-qualified incentive stock options).  Options become exercisable at
the date of grant or in equal annual  installments  over a period of one to four
years from the date of grant.  The options  generally  expire either five or ten
years after the date of grant.

         The 1996 Plan also provides for the grant of stock appreciation rights,
restricted units,  performance awards and other stock-based  awards. The Company
had no such awards or rights outstanding at July 31, 1999 or 1998.

           No compensation  cost has been recognized for its stock option grants
  to  employees  under APB No. 25. Total  compensation  cost  recognized  in the
  statements of operations for options granted to  non-employees  under SFAS No.
  123 during the years ended July 31, 1999,  1998, and 1997,  was $203,000,  $0,
  and $0,  respectively.  Pro forma information  regarding net income (loss) and
  net  income  (loss)  per share is  required  under  SFAS No.  123 and has been
  determined as if the Company had  accounted for all 1999,  1998 and 1997 stock
  option  grants  based on the fair  value  method.  The pro  forma  information
  presented below is not representative of the effect stock options will have on
  pro forma net income (loss) or net income (loss) per share for future years.

           The fair value of each option grant is estimated on the date of grant
  using the Black-Scholes multiple  option-pricing model. The following weighted
  average  assumptions were used for grants in 1999,  1998, and 1997:  risk-free
  interest rates of 5.92%, 5.5% and 5.94%, respectively; an expected option life
  of 7.52 years, 7.69 years and 4.92 years, respectively; expected volatility of
  90%, 114% and 96%, respectively; and dividend yield of zero.

           The Black-Scholes  method is one of many models used to calculate the
  fair value of options that are freely  tradable,  fully  transferable and that
  have no vesting  restrictions.  These  models also require  highly  subjective
  assumptions,  including  future stock price volatility and expected time until
  exercise, which greatly affect the calculated values.

           Had  compensation  cost for these plans been determined  based on the
  fair value of awards at the grant date,  as  prescribed  by SFAS No. 123,  net
  loss and net loss per share would have been as follows:

  (1) SFAS No. 123  applies to awards  granted in fiscal  years that begin after
  December 15, 1994.  Consequently,  the effects of applying  SFAS No. 123 shown
  here are not likely to be representative of the effects in future years due to
  the  exclusion  of awards  granted in prior years but vesting  (and  therefore
  expensed) in 1997, 1998, and 1999.

         A provision of the Internal  Revenue Code requires the  utilization  of
  net operating losses be limited when there is a change of more than 50 percent
  in ownership of the Company.  Such a change  occurred in December  1997.  This
  ownership  change  may  limit  the  utilization  of any net  operating  losses
  incurred prior to the change in ownership date.

           Gregory J. Frazer, Ph.D., an officer and director of the Company, and
  Mr.  Frazer's  wife,  were  shareholders  in certain  Hearing Care  Associates
  corporations  that the Company acquired during the fiscal years ended July 31,
  1998 and 1997.  During the fiscal year ended July 31, 1999, the Company issued
  a  three-year  promissory  note  to Mr.  Frazer  in the  principal  amount  of
  $102,000, payable in equal quarterly installments, in connection with purchase
  price  adjustments  for hearing  care  centers  previously  acquired  from Mr.
  Frazer. The Company also entered into expanded non-compete agreements with Mr.
  Frazer and his wife that pay them a total of $10,758 per month until September
  2001. For the fiscal year ended July 31, 1998, the  consideration  paid to Mr.
  Frazer  and  his  wife  in  connection  with  the   acquisitions  and  related
  non-competition  agreements  consisted of $242,179 in cash and $80,520 payable
  in installments over three years. The consideration paid to Mr. Frazer and his
  wife during the fiscal year ended July 31, 1997,  totaled $933,000 in cash and
  294,071 Common Shares at a price of $5.00 per share.

           On May 8, 1997,  Brandon M.  Dawson,  an officer and  director of the
  Company,  exercised  options for 50,000 Common  Shares at $1.35 per share.  In
  connection with the exercise, the Company made loans of $67,500 and $91,000 to
  Mr.  Dawson on May 8, 1997,  and April 24,  1998,  respectively,  to allow Mr.
  Dawson to pay the aggregate  exercise  price of the options and taxes incurred

           Operating Leases
           ----------------

           The following is a schedule by year of future  minimum lease payments
  for non-cancelable operating leases at July 31, 1999 (in thousands):

           2000                                                    $1,698
           2001                                                     1,506

           2003                                                       794
           2004                                                       557
           Thereafter                                                 409
                                                                   ------
           Total minimum lease payments                            $6,119
                                                                   ======

           Rental expense under operating leases was $2,236,000,  $1,426,000 and
  $810,000 for the years ended July 31, 1999, 1998, and 1997, respectively.

           Contingent Payments
           -------------------

           The terms of certain of the Company's acquisition  agreements provide
  for additional  consideration to be paid if the acquired  entity's revenues or
  results  of  operations   exceed  certain  target  levels.   Such   additional
  consideration  is paid in cash  and is  recorded  when  earned  as  additional
  purchase  price.  The  maximum  amount of  contingent  consideration  that the
  Company may be required  to pay for fiscal  2000 is  $520,000  and  $1,100,000
  thereafter.

           Insurance
           ---------

           In the normal course of business,  the Company may become a defendant
  or plaintiff in various  lawsuits.  Although a successful  claim for which the
  Company is not fully  insured  could have a material  effect on the  Company's
  financial condition,  management is of the opinion that it maintains insurance
  at levels sufficient to insure itself against the normal risk of operations.

  NOTE 12.  SEGMENT INFORMATION

         The Company  adopted  SFAS No. 131  "Disclosures  about  Segments of an
Enterprise and Related  Information" during fiscal 1999. In accordance with SFAS
No. 131, the Company has  identified a single  operating  segment:  the sale and
servicing of hearing instruments and the provision of audiology services.  Sales
are primarily to individual  consumers.  No customer constituted more than 5% of
total revenues. Revenues by country were as follows for the years ended July 31:

  NOTE 13.  SUBSEQUENT EVENTS

         On October 1, 1999, the Company issued  2,500,000  Series B Convertible
Preferred Shares (the "Series B Shares") in a private  placement for $10,000,000
in cash. In connection with the sale of the Series B Shares,  the Company agreed
to  reduce  the  exercise  price  of its  outstanding  share  purchase  warrants
entitling  the  holder  thereof  to  purchase   2,000,000   Common  Shares  (the
"Warrants")  from $12.00 to $6.75 per share,  to extend the  exercise  period to
October 1, 2004,  and to remove the  limitation on the number of shares that may
be issued upon a cashless exercise of the Warrants.  The Corporation also agreed
to  submit  certain  amendments  to  the  terms  of  the  Series  A  Shares  for
consideration  and  approval by the  Company's  shareholders  at the 1999 annual
meeting of  shareholders.  The proposed  amendments to the terms of the Series A
Shares  provide that dividends  payable  thereon may be paid in Common Shares at
the option of the Company until December 24, 2002, and thereafter  only in cash,
and lower the earnings and share price  thresholds to avoid specified  increases
in the dividend rate and as a condition to mandatory  conversion of the Series A
Shares.

         The  Series B Shares  are  initially  convertible  at the option of the
holder on a one-for-one basis into 2,500,000 Common Shares at a conversion price
of $4.00 per share.  The  conversion  rate is subject to  increase to the extent
that the Company's  receivables as of July 31, 1999,  that are collected by July
31,  2000,  total  less than  $4,736,000,  as well as to  adjustments  for stock
dividends,  stock  splits,  recapitalizations,  and  other  similar  events.  In
addition,  until the Company attains specified  quarterly earnings targets,  the
conversion   rate  will  increase   beginning   October  31,  2000,   such  that
approximately 200,000 additional Common Shares would be issuable upon conversion
at that date with  respect to the four fiscal  quarters  then ended.  Additional
adjustments will be made each quarter thereafter as long as the earnings targets
have not been met. The amount of such quarterly  adjustments  will be based on a
factor of 2 percent  of the  original  purchase  price plus the sum of all prior
adjustments  until  November  1, 2004,  increasing  in steps  thereafter  to 4.5
percent  beginning  November 1, 2006.  Once the  Company  has met the  specified
earnings targets for four consecutive fiscal quarters, no further adjustments in
the  conversion  rate will be made. The Series B Shares are subject to mandatory
conversion  at the option of the  Company if certain  share  price and  earnings
targets are met.

         Cash  dividends will accrue on the Series B Shares at an annual rate of
8 percent  of the  conversion  price  then in effect  until  November  1,  2004,
increasing  in steps  thereafter  to 18  percent  beginning  November  1,  2006,
provided that the Corporation has met specified  quarterly earnings targets.  If
the  Corporation  has not met the earnings  targets by July 31, 2002,  dividends
will not accrue or be payable on the  Series B Shares.  Upon  conversion  of the
Series B Shares, any accumulated dividends will be forfeited.

         In September of 1999, the Company  acquired 4 hearing care centers in 2
  transactions  for a total purchase price of $70,000 in cash. Each  transaction
  was accounted for as a purchase.

  NOTE 14.  CANADIAN VERSUS U.S. GAAP

           As  of  July  31,  1999,  1998,  and  1997  there  were  no  material
  differences between Canadian generally accepted accounting principles ("GAAP")
  and U.S. GAAP.

                                  SCHEDULE "A"

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

PROVISIONS ATTACHING TO THE COMMON SHARES

Voting Rights

i)       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;

Dividends and Other Distributions

ii)      the holders of the Common  Shares  shall be  entitled  to receive  such
         dividends as the directors of the Corporation may, in their discretion,
         declare thereon; and

iii)     in the  event of the  liquidation,  dissolution  or  winding-up  of the
         Corporation or other distribution of its assets among the shareholders,
         the  holders of the Common  Shares  shall be  entitled  to receive  the
         remaining property of the Corporation.

PURSUANT TO THE  SPECIAL  MEETING OF  SHAREHOLDERS  OF THE  CORPORATION  HELD ON
FEBRUARY 9, 1998, ITEM NO. 2 OF THE ARTICLES OF THE CORPORATION  WERE AMENDED IN
ACCORDANCE WITH THE PROVISIONS OF SECTION 167(1)(F) OF THE BUSINESS CORPORATIONS
ACT (ALBERTA) ON FEBRUARY 9, 1998 BY THE ADDITION OF THE FOLLOWING PROVISIONS:



<PAGE>


         Simultaneously   with  the  effective   date  of  this  amendment  (the
         "Effective  Date"),  each of the Corporation's  Common Shares,  without
         nominal or par value,  issued and outstanding  immediately prior to the
         Effective  Date (the  "Old  Common  Shares")  shall  automatically  and
         without any action on the part of the holder thereof be reclassified as
         and changed into one-fifth (1/5) of a Common Share,  without nominal or
         par value  (the "New  Common  Shares"),  subject  to the  treatment  of
         fractional  share  interests  as  described  below.  Each  holder  of a
         certificate or certificates  which  immediately  prior to the Effective
         Date represented outstanding Old Common Shares (the "Old Certificates,"
         whether one or more) shall be entitled  to receive  upon  surrender  of
         such  Old  Certificates  to  the   Corporation's   Transfer  Agent  for
         cancellation,  a certificate or certificates  (the "New  Certificates,"
         whether one or more) representing the number of whole New Common Shares
         into which and for which the Old Common Shares formerly  represented by
         such Old Certificates so surrendered,  are reclassified under the terms
         hereof.  From and after the  Effective  Date,  Old  Certificates  shall
         represent  only the  right to  receive  New  Certificates  (and,  where
         applicable,  cash in lieu of  fractional  shares,  as  provided  below)
         pursuant  to  the  provisions   hereof.   No   certificates   or  scrip
         representing  fractional  share  interests in New Common Shares will be
         issued,  and no such fractional  share interest will entitle the holder
         thereof

<PAGE>
                                      -3-

         to vote, or to any rights of a shareholder of the Corporation. A holder
         of Old  Certificates  shall  receive,  in lieu of any fraction of a New
         Common  Share to which the holder would  otherwise be entitled,  a cash
         payment  therefor on the basis of the  closing  price of the Old Common
         Shares on The Alberta Stock  Exchange on the Effective  Date (or in the
         event the Common Shares are not so traded on the Effective  Date,  such
         closing  price on the next  preceding  day on which  such  shares  were
         traded on The Alberta Stock Exchange). If more than one Old Certificate
         shall  be  surrendered  at  one  time  for  the  account  of  the  same
         shareholder,  the  number  of whole  New  Common  Shares  for which New
         Certificates  shall be  issued  shall be  computed  on the basis of the
         aggregate   number  of  Old  Common  Shares   represented  by  the  Old
         Certificates  so  surrendered.  In the  event  that  the  Corporation's
         Transfer Agent  determines  that a holder of Old  Certificates  has not
         tendered all his  certificates  for exchange,  the Transfer Agent shall
         carry  forward  any  fractional  share until all  certificates  of that
         holder  have  been   presented  for  exchange  such  that  payment  for
         fractional  shares to any one person shall not exceed the value of four
         Old Common  Shares.  If any New  Certificate  is to be issued in a name
         other than that in which the Old Certificates  surrendered for exchange
         are  issued,  the Old  Certificates  so  surrendered  shall be properly
         endorsed and otherwise in proper form for  transfer,  and the person or
         persons  requesting  such  exchange  shall  affix any  requisite  stock
         transfer  tax stamps to the Old  Certificates  surrendered,  or provide
         funds for their  purchase,  or  establish  to the  satisfaction  of the
         Corporation's  Transfer Agent that such taxes are not payable. From and
         after the Effective  Date the amount of capital  represented by the New
         Common  Shares  into  which  and for which the Old  Common  Shares  are
         reclassified  under the terms hereof shall be the same as the amount of
         capital  represented  by the Old Common Shares so  reclassified,  until
         thereafter reduced or increased in accordance with applicable law.



PROVISIONS ATTACHING TO THE PREFERRED SHARES

Directors' Authority to Issue in One or More Series
- ---------------------------------------------------

i)       the  Preferred  Shares  may from  time to time be issued in one or more
         series and  subject to the  following  provisions,  and  subject to the
         sending of articles of amendment in prescribed  form,  and the issuance
         of a certificate of amendment in respect thereof, the directors may fix
         from time to time  before  such issue the number of shares  which is to
         comprise  each  series  and  the   designation,   rights,   privileges,
         restrictions  and  conditions  attaching  to each  series of  Preferred
         Shares including, without limiting the generality of the foregoing, the
         rate or amount of dividends or the method of calculating dividends, the
         dates of payment thereof,  the redemption,  purchase and/or  conversion
         prices  and  terms  and  conditions  of  redemption,   purchase  and/or
         conversion, and any sinking fund or other provisions;

<PAGE>
                                      -4-

ii)      the Preferred Shares of each series shall,  with respect to the payment
         of dividends and the distribution of assets or return of capital in the
         event of  liquidation,  dissolution  or winding-up of the  Corporation,
         whether  voluntary  or  involuntary,  or any other return of capital or
         distribution of assets of the Corporation  among its  shareholders  for
         the  purpose  of  winding  up its  affairs,  rank on a parity  with the
         Preferred  Shares of every other  series and be entitled to  preference
         over the  Common  Shares and over any other  shares of the  Corporation
         ranking  junior to the Preferred  Shares.  The Preferred  Shares of any
         series may also be given such other preferences,  not inconsistent with
         these  articles,  over the Common  Shares  and any other  shares of the
         Corporation  ranking junior to such Preferred Shares as may be fixed in
         accordance with clause (i) above;

iii)     if any cumulative dividends or amounts payable on the return of capital
         in respect of a series of  Preferred  Shares are not paid in full,  all
         series  of  Preferred  Shares   participate   rateably  in  respect  of
         accumulated dividends and return of accumulated dividends and return of
         capital; and

iv)      unless the directors  otherwise  determine in the articles of amendment
         designating a series, the holder of each share of a series of Preferred
         Shares  shall not,  except as  otherwise  specifically  provided in the
         Business  Corporations Act (Yukon), be entitled to receive notice of or
         vote at any meeting of the shareholders.


                        FIRST SERIES OF PREFERRED SHARES
                        --------------------------------

Pursuant to the  Resolutions of the Directors of the  Corporation,  duly passed,
and in  accordance  with  subsection  27(5)  of  the  Business  Corporation  Act
(Alberta),  the Articles of the Corporation  were amended December 16, 1997 such
that the first series of Preferred  Shares of the  Corporation are designated as
"Series  A  Convertible   Preferred   Shares"  with  such  rights,   privileges,
restrictions  and  conditions  attaching to the shares of such series as are set
forth as follows:

                      SERIES A CONVERTIBLE PREFERRED SHARES

                   "1.  Number  and   Designation.   The  number  of  shares  to
         constitute  this series shall be 13,333,333 and the designation of such
         shares   shall  be  the  "Series  A   Convertible   Preferred   Shares"
         (hereinafter  called "this Series").  The number of shares constituting
         this Series may be decreased  from time to time by action of the Board,
         but not below the number of shares of this Series then outstanding. All
         shares  of this  Series  shall  be  identical  with  each  other in all
         respects.  The shares of this  Series  shall rank  senior to the common
         shares (the "Common  Shares") of the  Corporation  as to cash dividends
         and  upon   liquidation,   as  described   below.  Any  amounts  herein
         referencing  share  prices or  numbers  of shares  shall be  subject to
         appropriate   adjustments   in  the   event   of  any   stock   splits,
         consolidations or the like.

                   "2. Dividend Rights.

                   (a) Subject to the  provisions of this Section 2, the holders
         of shares of this Series shall be entitled to receive  when,  as and if
         declared  by the  Board,  out of  assets  legally  available  therefor,
         cumulative  dividends  ("Dividends")  at the applicable  rate per annum
         specified  in Section 2(b) hereof from the date of issuance and payable
         in accordance  with Section 2(c) hereof.  Dividends shall be cumulative
         from the date of initial  issuance  of the shares of this  Series  (the
         "Initial Issuance Date"),  whether or not there shall be assets legally
         available  for the  payment  of such  Dividends.  In the event that the
         Board  shall  declare a  Dividend,  subject  to  applicable  regulatory
         approvals,  such  Dividend  may,  at the  discretion  of the Board,  be
         payable in Common  Shares.  The number of Common Shares to be issued to
         the  holders of shares of this Series upon the payment of a Dividend in
         Common  Shares  shall be the  amount of the  Dividends  payable to such
         holder  pursuant to this Section 2 divided by either (i) (if the Common
         Shares  are not  traded on the New York Stock  Exchange,  the  American
         Stock  Exchange or the Nasdaq  National  Market) U.S. $1.35 or (ii) (if
         the  Common  Shares  are  traded on the New York  Stock  Exchange,  the
         American  Stock  Exchange  or the Nasdaq  National  Market) the average
         Market Price of the Common Shares as such term is defined below for the
         ten (10) trading  days  immediately  preceding  the Record Date as such
         term is defined in Section 2(c) hereof.

                            For all purposes  hereof,  the term "Market Price of
         the Common  Shares" as of any  specified  date shall  mean:  (i) if the
         Common  Shares are listed or admitted for trading on one or more United
         States national securities  exchanges,  the daily closing price for the
         Common Shares on the  principal  exchange in the United States on which
         the Common Shares are listed;  (ii) if the Common Shares are not listed
         or  admitted  for  trading on any  United  States  national  securities
         exchange,  the daily  closing price for the Common Shares on the Nasdaq
         National or Nasdaq  Small-Cap  Market  ("Nasdaq");  (iii) if the Common
         Shares  are not  listed or  admitted  for  trading  on a United  States
         national  securities  exchange or on Nasdaq, the daily closing price of
         the Common  Shares on the principal  stock  exchange in Canada on which
         the Common Shares are listed  (expressed in United States dollars based
         upon the noon  buying  rate in New York  City for  cable  transfers  in
         Canadian  dollars as  certified  for  customs  purposes  by the Federal
         Reserve Bank of New York);  (iv) if the Common Shares are not listed or
         admitted to trading on any United States national or Canadian  national
         securities  exchange or on Nasdaq,  the average of the reported bid and
         asked   prices  on  the  trading  day   preceding   such  date  in  the
         over-the-counter  market as furnished by the National Quotation Bureau,
         Inc., or, if such firm is not then engaged in the business of reporting
         such prices, as furnished by any member of the National  Association of
         Securities Dealers,  Inc. selected by the Company; or (v) if the Common
         Shares are not publicly traded,  the Market Price for such day shall be
         the fair market value thereof determined jointly by the Company and the
         holder of a majority  of the shares of this  Series  then  outstanding;
         provided,  however,  that if such parties are unable to reach agreement
         within  a  reasonable  period  of  time,  the  Market  Price  shall  be
         determined  in good faith by the  independent  investment  banking firm
         selected  jointly by the  Company  and the holder of a majority  of the
         shares of this Series then  outstanding or, if that selection cannot be
         made within an additional 15 days, by an independent investment banking
         firm  selected by the American  Arbitration  Association  in accordance
         with its rules.

                   "(b) The  Dividend per share of this Series shall be computed
         based  upon a rate per annum of 5% on a base  amount of U.S.  $1.35 per
         share of this Series (the "Base  Amount").  The Dividend rate per annum
         shall be subject  to  increase  in the event that all of the  following
         conditions (the "Triggering Conditions") have not been satisfied by the
         dates specified below: (i) the Common Shares are listed on the New York
         Stock  Exchange,  the American  Stock  Exchange or the Nasdaq  National
         Market;  (ii) the  Common  Shares  are  traded  on the New  York  Stock
         Exchange,  the American Stock Exchange or the Nasdaq National Market at
         a Market Price greater than U.S.  $2.40 per Common Share on each of the
         10  consecutive  trading  days  preceding  such  date;  and  (iii)  the
         Corporation's  net income  (excluding  profit or loss on  disposal of a
         significant  part of the Company's  assets or separate segment thereof,
         gains on restructuring payables,  gains or losses on the extinguishment
         of debt,  expropriations  of  property,  gains or  losses  that are the
         direct result of a major casualty,  or one-time  losses  resulting from
         prohibition  under a  newly-enacted  law or  regulation)  before income
         taxes,  Dividends  on the  shares of this  Series and  amortization  of
         goodwill and covenants not to compete for the three consecutive  fiscal
         quarters  preceding  such date,  as  reported  in or  derived  from the
         Corporation's quarterly or annual reports filed with the Securities and
         Exchange Commission,  shall have averaged at least U.S. $0.07 per fully
         diluted Common Share per fiscal quarter,  provided,  however, in making
         such  calculation,  the Common  Shares  issuable  upon  exercise of the
         warrants issued to Warburg Pincus Ventures, L.P. ("Warburg"),  pursuant
         to that certain Warrant  Agreement  between the Corporation and Warburg
         relating to warrants to purchase 10,000,000 Common Shares (the "Warrant
         Agreement"),  shall be excluded  but Common  Shares  issuable  upon the
         conversion  of the shares of this Series shall not. All  references  to
         per share amounts or prices with respect to the  Triggering  Conditions
         shall be appropriately adjusted for any subdivision,  consolidation, or
         reclassification of the Common Shares. Until the Triggering  Conditions
         have been satisfied, the Dividend rate per annum shall be (A)15% of the
         Base Amount per share of this Series from and after January 1, 2003 and
         payable in accordance  with Section 2(c) hereof  commencing  January 1,
         2004;  (B) 18% of the Base  Amount  per share of this  Series  from and
         after  January 1, 2004 and  payable in  accordance  with  Section  2(c)
         hereof commencing January 1, 2005; and (C) thereafter,  21% of the Base
         Amount  per share of this  Series  from and after  January  1, 2005 and
         payable in accordance  with Section 2(c) hereof  commencing  January 1,
         2006.  Upon the  satisfaction  of all the  Triggering  Conditions,  the
         Dividend per share of this Series  shall be computed  based upon a rate
         per annum of 5% of the Base  Amount.  Accruals of  Dividends  shall not
         bear  interest.  All Dividends  declared upon the shares of this Series
         shall be declared pro rata per share.

                   "(c) The record date for the  determination of the holders of
         shares of this Series who shall be entitled to receive  Dividends  (the
         "Record  Date") shall be the first  business day of each calendar year,
         and only the  holders of shares of this  Series of record on the Record
         Date shall be entitled to receive such Dividends. All Dividends payable
         to such  holders  of  record  shall be paid on the tenth  business  day
         following the Record Date on each issued and outstanding  share of this
         Series.

                   "(d)  Dividends  payable  on  shares of this  Series  for any
         period other than a full dividend period shall be computed on the basis
         of a 360-day year  consisting  of twelve  30-day  months.  Any Dividend
         payment made on shares of this Series  shall first be credited  against
         the earliest  accumulated but unpaid  Dividends due with respect to the
         shares of this Series.

                  "(e) No  dividends  shall be declared or paid or set aside for
         payment  on  any  share  capital  of  the  Corporation  ranking,  as to
         dividends, on a parity with or subordinate to the shares of this Series
         for  any  period  unless  full  accumulated   Dividends  have  been  or
         contemporaneously   are  declared  and  paid  or  declared  and  a  sum
         sufficient  for the payment  thereof set aside for such  payment on the
         shares of this Series for all Dividend periods  terminating on or prior
         to the date of payment of such  dividends.  When Dividends are not paid
         in full on the shares of this Series and any other preferred  shares of
         the  Corporation  ranking  with  respect to payment of  dividends  on a
         parity with the shares of this Series,  all dividends  declared or paid
         upon shares of this  Series and such other  preferred  shares  shall be
         declared and paid pro rata so that the amount of dividends declared and
         paid on the shares of this Series and such other preferred shares shall
         in all  cases  bear to each  other  the  same  ratio  that  accumulated
         dividends  per  share  (which  in the case of  noncumulative  preferred
         shares  shall  not  include  any  accumulation  in  respect  of  unpaid
         dividends for prior dividend periods) on shares of this Series and such
         other  preferred  shares bear to each other.  Except as provided in the
         preceding sentence, unless full accumulated Dividends have been paid or
         declared  and a sum  sufficient  for the payment  thereof set aside for
         payment,  no dividends (other than dividends or  distributions  paid in
         Common  Shares,  or  options,  warrants or rights to  subscribe  for or
         purchase Common Shares, or, in each case, any other series of shares of
         the Corporation  ranking subordinate to the shares of this Series as to
         dividends  and upon  liquidation)  shall be declared  and paid or a sum
         sufficient  for the payment  thereof set aside for payment or any other
         distribution declared or made upon the Common Shares or any other class
         of shares of the Corporation ranking subordinate to or on a parity with
         the  shares of this  Series as to  dividends  or upon  liquidation.  No
         Common Shares or shares of any other class of shares of the Corporation
         ranking subordinate to or on a parity with the shares of this Series as
         to  dividends  or upon  liquidation  shall be  redeemed,  purchased  or
         otherwise acquired for any consideration (and no funds shall be paid to
         or made  available  for a sinking fund for the  redemption  of any such
         share  capital)  by the  Corporation  (except  by  conversion  into  or
         exchange  for  shares of the  Corporation  ranking  subordinate  to the
         shares of this Series as to dividends  and upon  liquidation  or except
         with respect to Common Shares that the Corporation has become obligated
         to redeem  prior to the  issuance of any shares of this Series upon the
         occurrence of specified  circumstances)  unless, in each case, the full
         accumulated  Dividends  shall  have  been  paid or  declared  and a sum
         sufficient  for the payment  thereof set aside for payment.  Holders of
         shares of this Series  shall not be entitled to any  dividend,  whether
         payable in cash,  property or stock, in excess of the full Dividends on
         such shares.

                  "(f)  Upon  conversion  of any  shares  of this  Series by any
         holder thereof pursuant to Section 7 hereof,  any Dividends accrued and
         payable to such holder shall be  forfeited  and the  Corporation  shall
         have no further  obligation to such holder of shares of this Series for
         such accumulated Dividends.

         involuntary dissolution,  liquidation,  or winding up of the affairs of
         the  Corporation,  after  payment or provision for payment of the debts
         and other  liabilities of the Corporation and any preferential  amounts
         payable with respect to securities of the Corporation  ranking prior to
         the shares of this Series ("Senior Preferred  Shares"),  the holders of
         shares of this Series shall be entitled to receive out of the assets

         of the Corporation  available for distribution to shareholders,  before
         any  distribution  of assets is made to holders of the Common Shares or
         any other share capital of the Corporation  ranking  subordinate to the
         shares of this Series, a liquidating distribution in an amount equal to
         the  greater of (i) U.S.  $1.35 per share of this Series plus an amount
         equal  to any  accrued  and  unpaid  Dividends  (including  accumulated
         Dividends,  whether  or not  declared)  to and  including  the  date of
         distribution or (ii) the amount  distributable to the holders of shares
         of this Series as if such  holders had  converted  their shares of this
         Series into  Common  Shares  pursuant  to Section 7 hereof  immediately
         prior to such dissolution,  liquidation or winding up of the affairs of
         the Corporation (plus accumulated Dividends,  whether or not declared).
         Amounts  payable  pursuant to clause (i) or (ii) of this  Section  3(a)
         shall be distributed ratably among the holders of shares of this Series
         in  proportion  to the  number  of shares of this  Series  held.  After
         payment to the  holders of shares of this  Series of the full amount to
         which such  holders  are  entitled as set forth  above,  the holders of
         shares  of this  Series  shall  have no  right  or  claim to any of the
         remaining assets of the Corporation.

                  "(b) If upon any such  dissolution,  liquidation or winding up
         of the  affairs  of the  Corporation,  the  assets  of the  Corporation
         distributable  among  the  holders  of shares  of this  Series  and the
         holders  of all other  classes  or series of shares of the  Corporation
         ranking  on  a  parity  with  the  shares  of  this  Series   shall  be
         insufficient  to permit the  payment  to them of the full  preferential
         amounts  to which  they are  entitled,  then the  entire  assets of the
         Corporation so to be distributed shall be distributed ratably among the
         holders of shares of this  Series  and such other  classes or series of
         shares of the  Corporation in proportion to the sum of the  accumulated
         dividends and the liquidation preferences per share.

                  "(c) The sale, conveyance, mortgage, pledge or lease of all or
         substantially all the assets of the Corporation shall be deemed to be a
         liquidation,  dissolution or winding up of the Corporation for purposes
         of this Section 3.

                  "4. Optional Redemption. (a) The shares of this Series may not
         be redeemed before the fifth  anniversary of the Initial Issuance Date.
         Thereafter,  the shares of this Series shall be redeemable  (subject to
         subsection 4(d) below) at the option of the Corporation, in whole or in
         part, at the  redemption  price,  which shall be an amount equal to the
         greater of (i) U.S.  $1.35 per share of this  Series plus the amount of
         any accrued and unpaid  Dividends  per share of this Series  (including
         accumulated Dividends, whether or not declared) or (ii) the Fair Market
         Value  of a share of this  Series  (as  defined  below).  For  purposes
         hereof,  the Fair Market  Value  shall be  determined  by a  nationally
         recognized  independent  investment  banking firm mutually agreed to by
         the  Corporation  and the  holder of a  majority  of the shares of this
         Series then outstanding, whose determination shall be conclusive.

                  "(b) (i) In case the Corporation  shall desire to exercise its
         right to redeem any shares of this Series, it shall give notice of such
         redemption  to holders of the shares of this  Series to be  redeemed as
         hereinafter provided in this Section 4(b).

                           "(ii)  Notice  of  redemption  shall  be given to the
                  holders  of shares of this  Series to be  redeemed  by mailing
                  such notice by  first-class  mail to their last  addresses  as
                  they

                  not less than 120  calendar  days  prior to the date fixed for
                  redemption.

                           "(iii)  Each  such  notice  of  redemption  (A) shall
                  specify the date fixed for redemption and the redemption price
                  at which shares of this Series are to be  redeemed,  (B) shall
                  state that payment of the  redemption  price for the shares of
                  this  Series  to be  redeemed  will be  made at the  principal
                  executive  offices of the Corporation,  upon  presentation and
                  surrender  of  certificates  representing  such shares of this
                  Series, and (C) if less than all the shares of this Series are
                  to be  redeemed,  shall  specify  the number of shares of this
                  Series  held by  each  holder  to be  redeemed.  In  case  any
                  certificate  representing  shares  of  this  Series  is  to be
                  redeemed in part only, the notice of redemption  which relates
                  to such  certificate  shall state the number of shares of this
                  Series  represented  by such  certificate  to be redeemed  and
                  shall  state  that on and  after  the  redemption  date,  upon
                  surrender  of  such   certificate,   a  new   certificate   or
                  certificates  for a number of shares of this  Series  equal to
                  the unredeemed portion thereof will be issued.

                           "(iv) If less than all the shares of this  Series are
                  to be redeemed,  the Corporation  shall effect such redemption
                  pro rata  among the  holders  thereof  (based on the number of
                  shares  of  this   Series  held  on  the  date  of  notice  of
                  redemption).

                  "(c) (i) If the giving of notice of redemption shall have been
         completed  as provided  above,  the shares of this Series  specified in
         such  notice  shall  become  redeemable,  and shall be  redeemed by the
         Corporation   upon   presentation  and  surrender  of  the  certificate
         representing  such shares,  on the date and at the place stated in such
         notice at the  redemption  price,  and on and after such date fixed for
         redemption,  notwithstanding  that any  certificate  for shares of this
         Series so called for  redemption  shall not have been  surrendered  for
         cancellation,  unless there shall have been a default in payment of the
         redemption price, all shares of this Series called for redemption shall
         no longer be deemed to be  outstanding,  and all rights with respect to
         such shares of this Series shall forthwith  cease and terminate  except
         only the right of the holders  thereof to receive from the  Corporation
         the redemption price,  without interest,  of the shares to be redeemed,
         and such shares shall not thereafter be transferred on the books of the
         Corporation or be deemed to be outstanding for any purpose whatsoever.

                           "(ii)   Upon    presentation   of   any   certificate
                  representing shares of this Series only a portion of which are
                  to be redeemed,  the Corporation shall  immediately  issue, at
                  its expense,  a new certificate or  certificates  representing
                  the shares of this Series not redeemed.

                  "(d)  Except  as  provided  in   paragraph   (a)  above,   the
         Corporation  shall have no right to redeem  the shares of this  Series.
         Any shares of this Series so  redeemed  shall be  permanently  retired,
         shall  no  longer  be  deemed  outstanding  and  shall  not  under  any
         circumstances  be reissued,  and the  Corporation may from time to time
         take such  appropriate  corporate  action as may be necessary to reduce
         the  authorized  shares  of this  Series  accordingly.  Nothing  herein
         contained  shall  prevent or restrict the purchase by the  Corporation,
         from time to time either at public or

                                      -10-

         private  sale, of the whole or any part of the shares of this Series at
         such price or prices as the Corporation  may determine,  subject to the
         provisions of applicable law.

                  "5. No Mandatory  Redemption.  The shares of this Series shall
         not be subject to mandatory redemption by the Corporation.

                  "6. Voting Rights.  (a) Each issued and  outstanding  share of
         this  Series  shall be  entitled  to the  number of votes  equal to the
         number of Common Shares of the  Corporation  into which each such share
         of this Series is  convertible  (as adjusted from time to time pursuant
         to  Section  7(a)  hereof),  at each  meeting  of  shareholders  of the
         Corporation  with  respect  to any and  all  matters  presented  to the
         shareholders  of the  Corporation  for their  action or  consideration.
         Except as provided by law, by the  provisions of paragraph (b) below or
         by the provisions  establishing  any other series of preferred stock of
         the Corporation,  holders of the shares of this Series and of any other
         outstanding  preferred  stock shall vote  together  with the holders of
         Common Shares as a single class.

                  (b) In  addition  to any other  rights  provided  by law,  the
         Corporation shall not amend,  alter or repeal the preferences,  special
         rights  or other  powers  of the  shares  of this  Series  or any other
         provision  of  the  Corporation's   constating   documents  that  would
         adversely  affect  the  rights  of the  holders  of the  shares of this
         Series,  including,  without limitation,  any increase in the number of
         shares of this Series,  without the written consent or affirmative vote
         of the holders of at least  66-2/3% of the then  outstanding  aggregate
         number  of such  adversely  affected  shares of this  Series,  given in
         writing or by vote at a meeting,  consenting or voting (as the case may
         be)  separately as a class.  For this  purpose,  the  authorization  or
         issuance  of any  series of  preferred  stock of the  Corporation  with
         preference  or priority  over,  or being on a parity with the shares of
         this  Series as to the right to  receive  either  dividends  or amounts
         distributable  upon  liquidation,  dissolution  or  winding  up of  the
         Corporation  shall be deemed to  adversely  affect  the  shares of this
         Series.

                  "7. Conversion. (a) Each share of this Series may be converted
         at any  time,  at the  option  of the  holder  thereof,  in the  manner
         hereinafter provided,  into fully-paid and nonassessable Common Shares,
         provided,  however, that on any redemption of any shares of this Series
         or any liquidation of the  Corporation,  the right of conversion  shall
         terminate  at the  close  of  business  on the full  business  day next
         preceding the date fixed for such  redemption or for the payment of any
         amounts  distributable  on  liquidation to the holders of the shares of
         this  Series.  The  initial  conversion  rate for shares of this Series
         shall be one Common Share for each one share of this Series surrendered
         for conversion,  representing an initial conversion price (for purposes
         of Section 7(g)) of U.S.  $1.35 per share of the  Corporation's  Common
         Shares (hereinafter, the "Conversion Price"). The applicable conversion
         rate and  Conversion  Price from time to time in effect are  subject to
         adjustment as hereinafter provided.

                  "(b)  Whenever  the  Conversion  Price  shall be  adjusted  as
         provided in Section 7(g) hereof,  the Corporation  shall forthwith file
         at each  office  designated  for the  conversion  of the shares of this
         Series,  a statement,  signed by any of the Chairman of the Board,  the
         President,  any Vice  President or the  Treasurer  of the  Corporation,
         showing in reasonable  detail the facts requiring such adjustment.  The
         Corporation   shall  also  cause  a  notice   setting  forth  any  such
         adjustments to be sent by mail, first class,  postage prepaid,  to each
         record holder of shares of this Series at his

<PAGE>
                                      -11-

         or its address appearing on the stock register.  If such notice relates
         to an  adjustment  resulting  from an event  referred  to in  paragraph
         7(g)(vii), such notice shall be included as part of the notice required
         to be mailed and published under the provisions of paragraph  7(g)(vii)
         hereof.

                  "(c) The right of conversion  shall be exercised by the holder
         by the surrender of the certificates representing shares of this Series
         to be converted to the  Corporation at any time during normal  business
         hours at the office or agency then  maintained by it for the conversion
         of shares of this  Series (the  "Conversion  Office"),  accompanied  by
         written notice to the Corporation of such holder's  election to convert
         and, if so required by the  Corporation or any conversion  agent, by an
         instrument of transfer,  in form satisfactory to the Corporation and to
         any conversion agent, duly executed by the registered holder or by such
         holder's  duly  authorized  attorney,  and transfer tax stamps or funds
         therefor, if required pursuant to Section 7(k).

                  "(d) As  promptly  as  practicable  after  the  surrender  for
         conversion of one or more certificates  representing any shares of this
         Series in the manner  provided in Section  7(c) and the payment in cash
         of  any  amount  required  by  the  provisions  of  Section  7(k),  the
         Corporation  will deliver or cause to be  delivered  at the  Conversion
         Office to or upon the  written  order of the holder of such  shares,  a
         certificate  or  certificates  representing  the number of full  Common
         Shares issuable upon such  conversion,  issued in such name or names as
         such  holder  may  direct,   subject  to  any  applicable   contractual
         restrictions  and any  restrictions  imposed by  applicable  securities
         laws.  Such  conversion  shall be deemed to have been made  immediately
         prior  to the  close  of  business  on the  date of such  surrender  of
         certificates  representing  shares of this  Series in proper  order for
         conversion,  and all rights of the holder of such shares as a holder of
         such  shares  shall  cease at such  time,  and the person or persons in
         whose name or names the  certificates  for such Common Shares are to be
         issued  shall be treated for all  purposes as having  become the record
         holder or holders  thereof at such time;  provided,  however,  that any
         such  surrender  on any  date  when  the  stock  transfer  books of the
         Corporation  shall be closed shall  constitute the person or persons in
         whose name or names the  certificates  for such Common Shares are to be
         issued  as the  record  holder  or  holders  thereof  for all  purposes
         immediately  prior to the close of business on the next  succeeding day
         on which such stock transfer books are opened.

                  "(e) "Upon conversion in the manner provided in this Section 7
         of only a portion of the number of shares of this Series represented by
         a certificate so surrendered  for  conversion,  the  Corporation  shall
         issue and deliver or cause to be delivered at the Conversion  Office to
         or  upon  the  written  order  of  the  holder  of the  certificate  so
         surrendered for conversion,  at the expense of the  Corporation,  a new
         certificate or certificates  representing  the number of shares of this
         Series  representing  the  unconverted  portion of the  certificate  so
         surrendered,  issued in such name or names as such  holder may  direct,
         subject to any applicable contractual restrictions and any restrictions
         imposed by applicable securities laws.

                  "(f)  All  shares  of  this  Series   which  shall  have  been
         surrendered for conversion as herein provided shall no longer be deemed
         to be outstanding and all rights with respect to such shares, including
         the rights,  if any, to receive  notices and to vote,  shall  forthwith
         cease and  terminate  except  only the right of the  holder  thereof to
         receive Common Shares in exchange  therefor.  Any shares of this Series
         so  converted  shall be retired and canceled and shall not be

         reissued,  and  the  Corporation  may  from  time  to  time  take  such
         appropriate  action as may be necessary to reduce the authorized shares
         of this Series accordingly.

                  (g) Anti-Dilution Provisions.

                  (i)  In  order  to  prevent  dilution  of  the  right  granted
hereunder, the Conversion Price shall be subject to adjustment from time to time
in accordance  with this  paragraph  7(g)(i).  At any given time the  Conversion
Price  shall be that  dollar (or part of a dollar)  amount the  payment of which
shall be  sufficient  at the  given  time to  acquire  one  Common  Share of the
Corporation  upon  conversion of shares of this Series.  Upon each adjustment of
the Conversion  Price  pursuant to this Section 7(g),  the registered  holder of
shares of this Series shall thereafter be entitled to acquire upon exercise,  at
the Conversion Price resulting from such adjustment, the number of Common Shares
of the  Corporation  obtainable by multiplying  the  Conversion  Price in effect
immediately prior to such adjustment by the number of shares of Common Shares of
the Corporation acquirable immediately prior to such adjustment and dividing the
product  thereof by the Conversion  Price  resulting from such  adjustment.  For
purposes  of this  Section  7(g),  the term  "Number  of  Common  Shares  Deemed
Outstanding" at any given time shall mean the sum of (x) the number of shares of
the  Corporation's  Common Shares  outstanding  at such time,  (y) the number of
Common Shares of the Corporation  issuable  assuming  conversion at such time of
all  outstanding  shares  of  the  Corporation's  other  series  of  convertible
preferred  stock, if any, and (z) the number of Common Shares of the Corporation
deemed to be  outstanding at such time under  subparagraphs  7(g)(ii)(1) to (8),
inclusive.

                  (ii)  Except as provided in  paragraph  7(g)(iii)  or 7(g)(vi)
below,  if and whenever on or after the Initial  Issuance Date, the  Corporation
shall issue or sell, or shall in accordance  with  subparagraphs  7(g)(ii)(1) to
(8), inclusive, be deemed to have issued or sold (such issuance or sale, whether
actual  or  deemed,  the  "Triggering  Transaction")  any  Common  Shares  for a
consideration per share less than

                  (I) (if the Common Shares are not traded on the New York Stock
         Exchange,  the American Stock Exchange or the Nasdaq  National  Market)
         the Conversion  Price in effect  immediately  prior to the time of such
         issuance  or  sale,  then  forthwith  upon  such  issuance  or sale the
         Conversion  Price shall,  subject to  subparagraphs  (1) to (8) of this
         Section 7(g)(ii), be reduced to the Conversion Price (calculated to the
         nearest tenth of a cent) determined by dividing: (i) an amount equal to
         the sum of (x) the product  derived by multiplying the Number of Common
         Shares  Deemed   Outstanding   immediately  prior  to  such  Triggering
         Transaction  by the  Conversion  Price  then in  effect,  plus  (y) the
         consideration,  if any,  received by the Company upon  consummation  of
         such Triggering Transaction,  by (ii) an amount equal to the sum of (x)
         the Number of Common Shares  Deemed  Outstanding  immediately  prior to
         such Triggering Transaction plus (y) the number of Common Shares issued
         (or deemed to be issued in accordance with subparagraphs 7(g)(ii)(1) to
         (8)) in connection with the Triggering Transaction; or

                  (II) (if the  Common  Shares  are traded on the New York Stock
         Exchange,  the American Stock Exchange or the Nasdaq  National  Market)
         the average Market Price for the ten trading days immediately preceding
         such issuance or sale, then forthwith upon such Triggering Transaction,
         the Conversion Price shall, subject to subparagraphs (1) to (8) of this
         Section 7(g)(ii),

<PAGE>
                                      -13-

         be reduced to the Conversion Price  (calculated to the nearest tenth of
         a cent)  determined  by  multiplying  the  Conversion  Price in  effect
         immediately  prior  to the  time of such  Triggering  Transaction  by a
         fraction,  the numerator of which shall be the sum of (x) the Number of
         Common Shares Deemed  Outstanding  immediately prior to such Triggering
         Transaction  and (y) the number of Common  Shares  which the  aggregate
         consideration  received by the Company upon such Triggering Transaction
         would  purchase at the average  Market  Price for the ten trading  days
         immediately preceding such Triggering Transaction,  and the denominator
         of which  shall be the  Number  of  Common  Shares  Deemed  Outstanding
         immediately after such Triggering Transaction.

                  For  purposes of  determining  the adjusted  Conversion  Price
under this paragraph 7(g)(ii),  the following subsections (1) to (8), inclusive,
shall be applicable:

                           (1) In case the  Corporation at any time shall in any
                  manner  grant  (whether   directly  or  by  assumption  in  an
                  amalgamation  or otherwise)  any rights to subscribe for or to
                  purchase, or any options for the purchase of, Common Shares or
                  any stock or other securities convertible into or exchangeable
                  for Common  Shares (such rights or options being herein called
                  "Options"  and  such  convertible  or  exchangeable  stock  or
                  securities  being  herein  called  "Convertible  Securities"),
                  whether  or not  such  Options  or the  right  to  convert  or
                  exchange  any  such  Convertible  Securities  are  immediately
                  exercisable,  and the price  per  share  for which the  Common
                  Shares are  issuable  upon  exercise,  conversion  or exchange
                  (determined by dividing (x) the total amount, if any, received
                  or  receivable by the  Corporation  as  consideration  for the
                  granting  of  such  Options,  plus  the  aggregate  amount  of
                  additional  consideration  payable to the Corporation upon the
                  exercise  of all  such  Options,  plus,  in the  case  of such
                  Options which relate to Convertible Securities,  the aggregate
                  amount of additional  consideration,  if any, payable upon the
                  issue  or sale of such  Convertible  Securities  and  upon the
                  conversion  or  exchange  thereof,  by (y) the  total  maximum
                  number of Common  Shares  issuable  upon the  exercise of such
                  Options or the  conversion  or  exchange  of such  Convertible
                  Securities)  shall be less than the  average  Market  Price in
                  effect for the ten trading days immediately  prior to the time
                  of the  granting  of such  Option  (if the  Common  Shares are
                  traded on the New York  Stock  Exchange,  the  American  Stock
                  Exchange  or the Nasdaq  National  Market)  or the  Conversion
                  Price in effect immediately prior to the time of such issuance
                  or sale (if the  Common  Shares are not traded on the New York
                  Stock  Exchange,  the  American  Stock  Exchange or the Nasdaq
                  National  Market),  then the  total  maximum  amount of Common
                  Shares  issuable  upon the exercise of such Options or, in the
                  case  of  Options  for   Convertible   Securities,   upon  the
                  conversion or exchange of such Convertible  Securities,  shall
                  (as of the date of granting  of such  Options) be deemed to be
                  outstanding   and  to  have  been   issued  and  sold  by  the
                  Corporation  for such price per share.  No  adjustment  of the
                  Conversion  Price  shall be made upon the actual  issuance  of
                  such Common  Shares or such  Convertible  Securities  upon the
                  exercise  of such  Options,  except as  otherwise  provided in
                  subparagraph (3) below.

                           (2) In case the  Corporation at any time shall in any
                  manner  issue  (whether   directly  or  by  assumption  in  an
                  amalgamation or otherwise) or sell any Convertible Securities,
                  whether or not the rights to  exchange  or convert  thereunder
                  are immediately

                  exercisable,  and the price per share for which Common  Shares
                  are issuable upon such  conversion or exchange  (determined by
                  dividing (x) the total amount  received or  receivable  by the
                  Corporation  as  consideration  for the  issue or sale of such
                  Convertible   Securities,   plus  the   aggregate   amount  of
                  additional  consideration,  if any, payable to the Corporation
                  upon the  conversion  or  exchange  thereof,  by (y) the total
                  maximum  number of Common Shares  issuable upon the conversion
                  or exchange of all such Convertible  Securities) shall be less
                  than the  average  Market  Price  in  effect  for the  ten-day
                  trading period  immediately prior to the time of such issue or
                  sale (if the  Common  Shares  are traded on the New York Stock
                  Exchange,  the American Stock Exchange or the Nasdaq  National
                  Market) or the Conversion Price in effect immediately prior to
                  the time of such  issuance  or sale (if the Common  Shares are
                  not traded on the New York Stock Exchange,  the American Stock
                  Exchange  or the  Nasdaq  National  Market),  then  the  total
                  maximum  number of Common Shares  issuable upon  conversion or
                  exchange of all such  Convertible  Securities shall (as of the
                  date of the issue or sale of such  Convertible  Securities) be
                  deemed to be  outstanding  and to have been issued and sold by
                  the Corporation for such price per share. No adjustment of the
                  Conversion  Price  shall be made upon the actual  issuance  of
                  such Common  Shares upon exercise of the rights to exchange or
                  convert under such Convertible Securities, except as otherwise
                  provided in subparagraph (3) below.

                           (3) If the purchase price provided for in any Options
                  referred to in subparagraph (1), the additional consideration,
                  if  any,  payable  upon  the  conversion  or  exchange  of any
                  Convertible  Securities  referred to in  subparagraphs  (1) or
                  (2), or the rate at which any Convertible  Securities referred
                  to  in  subparagraph  (1)  or  (2)  are  convertible  into  or
                  exchangeable for Common Shares shall change at any time (other
                  than  under or by reason of  provisions  designed  to  protect
                  against dilution of the type set forth in paragraphs  7(g)(ii)
                  or 7(g)(iv)),  the  Conversion  Price in effect at the time of
                  such change shall  forthwith be readjusted  to the  Conversion
                  Price  which  would  have been in effect at such time had such
                  Options or Convertible  Securities still outstanding  provided
                  for such changed purchase price,  additional  consideration or
                  rate,  as the case  may be,  at the  time  initially  granted,
                  issued or sold.  If the  purchase  price  provided  for in any
                  Option  referred to in  subparagraph  (1) or the rate at which
                  any Convertible Securities referred to in subparagraphs (1) or
                  (2) are convertible  into or  exchangeable  for Common Shares,
                  shall be reduced at any time under or by reason of  provisions
                  with respect  thereto  designed to protect  against  dilution,
                  then  in  case of the  delivery  of  Common  Shares  upon  the
                  exercise of any such Option or upon  conversion or exchange of
                  any such  Convertible  Security,  the Conversion Price then in
                  effect   hereunder   shall   forthwith  be  adjusted  to  such
                  respective  amount as would have been obtained had such Option
                  or  Convertible  Security  never been issued as to such Common
                  Shares and had adjustments  been made upon the issuance of the
                  Common Shares delivered as aforesaid,  but only if as a result
                  of  such  adjustment  the  Conversion  Price  then  in  effect
                  hereunder is hereby reduced.

                           (4)  On  the   expiration   of  any   Option  or  the
                  termination   of  any  right  to  convert  or   exchange   any
                  Convertible  Securities,  the Conversion  Price then in effect
                  hereunder shall forthwith be increased to the Conversion Price
                  which would have been in effect at the time of such expiration
                  or termination had such Option or Convertible Securities, to

<PAGE>
                                      -15-

                  the extent outstanding immediately prior to such expiration or
                  termination, never been issued.

                           (5) In case any Options shall be issued in connection
                  with the issue or sale of other securities of the Corporation,
                  together  comprising  one  integral  transaction  in  which no
                  specific  consideration  is  allocated  to such Options by the
                  parties  thereto,  such  Options  shall be deemed to have been
                  issued without consideration.

                           (6) In case any Common Shares, Options or Convertible
                  Securities  shall be  issued  or sold or  deemed  to have been
                  issued or sold for cash, the  consideration  received therefor
                  shall be deemed to be the amount  received by the  Corporation
                  therefor  (before  deduction  for  expenses  or  underwriters'
                  discounts or  commissions  related to such issue or sale).  In
                  case any  Common  Shares,  Options or  Convertible  Securities
                  shall be issued or sold for a  consideration  other than cash,
                  the amount of the  consideration  other than cash  received by
                  the Corporation shall be the fair value of such  consideration
                  as  determined  in good faith by the Board of Directors of the
                  Corporation.

                           (7) In case the Corporation  shall declare a dividend
                  or make any other  distribution  upon the share capital of the
                  Corporation payable in Common Shares,  Options, or Convertible
                  Securities,  then in such case any Common  Shares,  Options or
                  Convertible  Securities,  as the  case  may  be,  issuable  in
                  payment of such  dividend or  distribution  shall be deemed to
                  have been issued or sold without consideration.

                           (8) For purposes of this paragraph 7(g)(ii),  in case
                  the  Corporation  shall  take a record of the  holders  of its
                  Common Shares for the purpose of entitling them (x) to receive
                  a dividend  or other  distribution  payable in Common  Shares,
                  Options or in Convertible Securities,  or (y) to subscribe for
                  or purchase Common Shares, Options or Convertible  Securities,
                  then such  record  date  shall be deemed to be the date of the
                  issue or sale of the Common  Shares deemed to have been issued
                  or sold upon the declaration of such dividend or the making of
                  such other  distribution  or the date of the  granting of such
                  right or subscription or purchase, as the case may be.

                  (iii) In the event the  Corporation  shall  declare a dividend
upon the Common Shares (other than a dividend  payable in Common Shares  covered
by subparagraph  7(g)(ii)(7))  payable  otherwise than out of earnings or earned
surplus, determined in accordance with generally accepted accounting principles,
including the making of appropriate  deductions for minority interests,  if any,
in subsidiaries (herein referred to as "Liquidating  Dividends"),  then, as soon
as possible after the conversion of any shares of this Series,  the  Corporation
shall,  subject to applicable  law, pay to the person  converting such shares of
this Series an amount equal to the aggregate  value at the time of such exercise
of all  Liquidating  Dividends  (including  but not limited to the Common Shares
which would have been issued at the time of such earlier  exercise and all other
securities  which would have been issued with  respect to such Common  Shares by
reason of stock splits,  stock dividends,  amalgamations or reorganizations,  or
for any other reason). For the purposes of this paragraph 7(g)(iii),  a dividend
other than in cash shall be considered payable out of earnings or earned surplus
only to the extent that such  earnings  or earned  surplus are charged an amount
equal to the fair  value of such  dividend  as  determined  in good faith by the
Board.

                                      -16-

                  (iv) In case  the  Corporation  shall  at any  time  subdivide
(other than by means of a dividend payable in Common Shares covered by paragraph
7(g)(ii)(7)) its outstanding  Common Shares into a greater number of shares, the
Conversion  Price  in  effect  immediately  prior to such  subdivision  shall be
proportionately reduced, and, conversely,  in case the outstanding Common Shares
of the  Corporation  shall be  combined  into a smaller  number of  shares,  the
Conversion  Price  in  effect  immediately  prior to such  combination  shall be
proportionately increased.

                  (v) If any capital  reorganization or  reclassification of the
share  capital of the  Corporation,  or  amalgamation  of the  Corporation  with
another  corporation,  or the sale of all or substantially  all of its assets to
another  corporation  shall be  effected  in such a way that  holders  of Common
Shares shall be entitled to receive  stock,  securities,  cash or other property
with respect to or in exchange for Common  Shares,  then, as a condition of such
reorganization,  reclassification,  amalgamation  or sale,  lawful and  adequate
provision  shall be made whereby the holders of shares of this Series shall have
the right to acquire and receive upon  conversion  of the shares of this Series,
which  right  shall be prior to the rights of the  holders  of stock  ranking on
liquidation  junior to this  Series  (but  after and  subject  to the  rights of
holders of Senior Preferred Shares,  if any), such shares of stock,  securities,
cash or other  property  issuable  or  payable  (as part of the  reorganization,
reclassification,  amalgamation or sale) with respect to or in exchange for such
number of  outstanding  Common  Shares  of the  Corporation  as would  have been
received upon  conversion of the shares of this Series at the  Conversion  Price
then in effect.  The Corporation will not effect any such  amalgamation or sale,
unless prior to the  consummation  thereof the  amalgamated  corporation  or the
corporation  purchasing such assets shall assume by written instrument mailed or
delivered  to the  holders of the shares of this  Series at the last  address of
each such holder  appearing on the books of the  Corporation,  the obligation to
deliver to each such holder such  shares of stock,  securities  or assets as, in
accordance  with the  foregoing  provisions,  such  holder  may be  entitled  to
receive. If a purchase,  tender or exchange offer is made to and accepted by the
holders of more than 50% of the  outstanding  Common Shares of the  Corporation,
the Corporation shall not effect any amalgamation or sale with the person having
made such offer or with any Affiliate (as defined below) of such person,  unless
prior to the consummation of such amalgamation or sale the holders of the shares
of this Series shall have been given a reasonable  opportunity  to then elect to
receive  upon the  conversion  of the  shares of this  Series  either the stock,
securities  or assets then  issuable  with  respect to the Common  Shares of the
Corporation or the stock,  securities or assets,  or the  equivalent,  issued to
previous  holders  of the  Common  Shares in  accordance  with such  offer.  For
purposes  hereof,  the term  "Affiliate"  with respect to any given person shall
mean any person  controlling,  controlled  by or under  common  control with the
given person.

                  (vi) The  provisions  of this  Section 7(g) shall not apply to
any Common Shares issued,  issuable or deemed  outstanding  under  subparagraphs
7(g)(ii)(1)  to (8) inclusive:  (i) to any person  pursuant to any stock option,
stock  purchase or similar plan or  arrangement  for the benefit of employees of
the Corporation or its  subsidiaries  in effect on the Initial  Issuance Date or
thereafter  adopted by the Board of Directors of the Corporation,  (ii) pursuant
to options,  warrants and conversion rights in existence on the Initial Issuance
Date,  (iii) upon exercise of the warrants of the Corporation  issued to Warburg
pursuant to the Warrant  Agreement or (iv) on  conversion  of the shares of this
Series or the sale of any additional shares of this Series.

                  (vii) In the event that:

                                      -17-

                  (1) the  Corporation  shall declare any cash dividend upon its
         Common Shares, or


                  (2) the Corporation shall declare any dividend upon its Common
         Shares  payable  in  stock  or  make  any  special  dividend  or  other
         distribution to the holders of its Common Shares, or

                  (3) the Corporation  shall offer for  subscription pro rata to
         the holders of its Common Shares any additional  shares of stock of any
         class or other rights, or

                  (4)   there   shall   be   any   capital   reorganization   or
         reclassification of the share capital of the Corporation, including any
         subdivision  or  combination  of  its  outstanding  Common  Shares,  or
         amalgamation of the Corporation  with, or sale of all or  substantially
         all of its assets to, another corporation, or

                  (5) there shall be a  voluntary  or  involuntary  dissolution,
         liquidation or winding up of the Corporation;

then, in connection with such event,  the Corporation  shall give to the holders
of the shares of this Series:

                  (A)      at least  twenty (20) days' prior  written  notice of
                           the date on which the books of the Corporation  shall
                           close or a record  shall be taken for such  dividend,
                           distribution   or   subscription    rights   or   for
                           determining  rights  to vote in  respect  of any such
                           reorganization, reclassification, amalgamation, sale,
                           dissolution, liquidation or winding up; and

                  (B)      in   the   case   of   any    such    reorganization,
                           reclassification,  amalgamation,  sale,  dissolution,
                           liquidation or winding up, at least twenty (20) days'
                           prior written  notice of the date when the same shall
                           take place.

Such notice in accordance with the foregoing  clause (A) shall also specify,  in
the case of any such dividend,  distribution or subscription rights, the date on
which the holders of Common Shares shall be entitled thereto, and such notice in
accordance  with the  foregoing  clause (B) shall also specify the date on which
the holders of Common  Shares shall be entitled to exchange  their Common Shares
for  securities  or  other  property   deliverable  upon  such   reorganization,
reclassification, amalgamation, sale, dissolution, liquidation or winding up, as
the case may be. Each such  written  notice  shall be given by first class mail,
postage  prepaid,  addressed  to the holders of the shares of this Series at the
address of each such holder as shown on the books of the Corporation.

                  (viii)  If at any time or from  time to time on or  after  the
Initial Issuance Date, the Corporation  shall grant,  issue or sell any Options,
Convertible  Securities or rights to purchase  property (the "Purchase  Rights")
pro rata to the record holders of the Common Shares of the  Corporation and such
grants,  issuances  or sales do not result in an  adjustment  of the  Conversion
Price under paragraph 7(g)(ii) hereof, then each holder of shares of this Series
shall be entitled to acquire  (within  thirty (30) days after the later to occur
of the initial  exercise date of such Purchase  Rights or receipt by such holder
of the notice

<PAGE>
                                      -18-

concerning  Purchase  Rights  to  which  such  holder  shall be  entitled  under
paragraph  7(g)(vii))  and upon the terms  applicable  to such  Purchase  Rights
either:

                  (A)      the aggregate Purchase Rights which such holder could
                           have  acquired  if it had held the  number  of Common
                           Shares  acquirable  upon conversion of shares of this
                           Series immediately before the grant, issuance or sale
                           of  such  Purchase  Rights;   provided  that  if  any
                           Purchase Rights were distributed to holders of Common
                           Shares    without   the    payment   of    additional
                           consideration by such holders, corresponding Purchase
                           Rights shall be distributed to the exercising holders
                           of the  shares  of this  Series  as soon as  possible
                           after such exercise and it shall not be necessary for
                           the  exercising  holder of the shares of this  Series
                           specifically to request delivery of such rights; or

                  (B)      in the event that any such Purchase Rights shall have
                           expired  or  shall  expire  prior  to the end of said
                           thirty (30) day period,  the number of Common  Shares
                           or the amount of  property  which such  holder  could
                           have acquired upon such exercise at the time or times
                           at which the Corporation granted, issued or sold such
                           expired Purchase Rights.

                  (ix) If any event  occurs as to which,  in the  opinion of the
Board,  the  provisions  of this Section 7(g) are not strictly  applicable or if
strictly  applicable  would not fairly  protect the rights of the holders of the
shares of this Series in accordance with the essential  intent and principles of
such  provisions,  then the Board shall make an adjustment in the application of
such provisions,  in accordance with such essential intent and principles, so as
to protect such rights as aforesaid,  but in no event shall any adjustment  have
the effect of increasing the Conversion Price as otherwise  determined  pursuant
to  any of the  provisions  of  this  Section  7(g)  except  in  the  case  of a
combination of shares of a type  contemplated in paragraph  7(g)(iv) and then in
no event to an amount larger than the Conversion  Price as adjusted  pursuant to
paragraph 7(g)(iv).

                  "(h) No  fractional  Common  Shares  shall be issued  upon the
         conversion  of any share or shares of this  Series.  If any  fractional
         interest in a Common Share  would,  except for the  provisions  of this
         Section 7(h), be deliverable upon the conversion of any share or shares
         of this  Series,  the  Corporation  shall  in lieu  of  delivering  the
         fractional  Common Share therefor  satisfy such fractional  interest by
         payment  to the  holder  of such  surrendered  share or  shares of this
         Series of an amount in cash equal (computed to the nearest cent) to the
         current market value of such fractional interest, computed on the basis
         of  the  Market  Price  of  the  Common  Shares  on the  date  of  such
         conversion,  provided,  however,  that no  amount  shall be paid by the
         Corporation to such holder of less than U.S. $5.00.

                  "(i) The Corporation shall be entitled to effect the mandatory
         conversion,  in whole or in  part,  of the  shares  of this  Series  in
         accordance with this Section 7 if all of the Triggering Conditions (set
         forth in Section 2(b) hereof) shall have been  satisfied as of the date
         of the notice described  below.  Upon such mandatory  conversion,  each
         share of this Series subject to such conversion shall be converted into
         Common Shares at the then effective  Conversion  Price for such shares.
         In case the  Corporation  shall desire to exercise the right to convert
         all or, as the case may

<PAGE>
                                      -19-

         be, any shares of this Series in accordance with the right to do so, it
         shall provide  notice to the holders of the shares of this Series to be
         converted as hereinafter provided in this Section 7(i).

                           "(i) A  notice  of  conversion  shall be given to the
         holders  of  shares  of this  Series  to be  converted  by  mailing  by
         first-class  mail to their last addresses as they shall appear upon the
         register  for  shares of this  Series not less than 120  calendar  days
         prior to the date fixed for conversion.

                           "(ii)  Each  such  notice  of  conversion  (A)  shall
         specify the date fixed for  conversion  and the number of Common Shares
         issuable to the holder of a share of this Series upon such  conversion,
         (B)  shall  state the  offices  or  agencies  to be  maintained  by the
         Corporation for the purpose of such conversion,  upon  presentation and
         surrender  of such  shares of this  Series and (C) if less than all the
         shares of this Series are to be converted,  shall specify the number of
         shares of this Series held by each  holder,  and the serial  numbers of
         the  certificates  thereof,  to be converted.  In case any  certificate
         representing shares of this Series is to be converted in part only, the
         notice of conversion which relates to such certificate  shall state the
         number of shares of this Series  represented by such  certificate to be
         converted and shall state that on and after the conversion  date,  upon
         surrender of such certificate,  a new certificate or certificates for a
         number  of  shares  of this  Series  equal to the  unconverted  portion
         thereof will be issued.

                  "(j)  The  Corporation  will at all  times  reserve  and  keep
         available,  solely for the  purposes of the  issuance of Common  Shares
         upon conversion of the shares of this Series, the full number of Common
         Shares as shall be issuable upon the conversion of all such outstanding
         shares of this Series.

                  "The  Corporation  will endeavor to comply with all securities
         laws regulating the offer and delivery of Common Shares upon conversion
         of the shares of this Series and, that if any Common Shares required to
         be reserved for purposes of conversion of the shares hereunder  require
         registration  with or approval of any governmental  authority under any
         U.S.  (federal or state) or Canadian law before such Common  Shares may
         be validly issued or delivered upon conversion,  the Corporation  will,
         in good faith and as expeditiously as possible, endeavor to secure such
         registration or approval, as the case may be.

                  "All Common  Shares which shall be issued upon  conversion  of
         the  shares  of this  Series  will  upon  issuance  be  fully  paid and
         nonassessable and not subject to preemptive rights.

                  "(k) The  issuance  of  certificates  for Common  Shares  upon
         conversion  of shares of this Series shall be made  without  charge for
         any stamp or other similar tax in respect of such issuance. However, if
         any such  certificate  is to be issued in a name other than that of the
         holder of record  of the share or shares of this  Series so  converted,
         the holder thereof shall pay to the  Corporation  the amount of any tax
         which may be  payable  in  respect  of any  transfer  involved  in such
         issuance or shall establish to the satisfaction of the Corporation that
         such tax has been paid or is not payable.

                                      -20-

                  "(l) In case (A) the  Corporation  shall take any action which
         would require an adjustment in the number of Common Shares  issuable to
         holders of shares of this Series upon  conversion  thereof  pursuant to
         Section 7(g) above;  or (B) there shall be a voluntary  or  involuntary
         dissolution,   liquidation   or  winding  up  of  the  affairs  of  the
         Corporation;

         then the  Corporation  shall  cause to be given to the  holders  of the
         shares of this Series at least ten days prior to the applicable  record
         date hereinafter  specified, a notice of (X) the date on which a record
         is to be taken for the purpose of any dividend,  distribution  or grant
         to holders of Common Shares which would require such an adjustment, or,
         if a record is not to be taken,  the date as of which  the  holders  of
         Common Shares of record to be entitled to such dividend,  distribution,
         or  grant  are  to  be  determined  or  (Y)  the  date  on  which  such
         reorganization,   reclassification,   amalgamation,   sale,   transfer,
         dissolution, liquidation or winding up is expected to become effective,
         and the date as of which it is expected  that holders of Common  Shares
         of record  shall be  entitled  to  exchange  their  Common  Shares  for
         securities  or other  property or other  assets  deliverable  upon such
         reorganization,   reclassification,   amalgamation,   sale,   transfer,
         dissolution, liquidation, or winding up. Failure to give such notice or
         any defect  therein  shall not affect the  legality  or validity of any
         proceedings described in subparagraphs (A) or (B) of this Section 7(l).

                  "8. Hold Period. A holder of shares of this Series shall in no
event sell or otherwise transfer any of the shares of this Series, or any Common
Shares issued upon the due conversion of any shares of this Series, for a period
of six months from the Initial  Issuance  Date. The  Corporation  shall issue or
cause to be  issued  certificates  representing  shares of this  Series,  and of
Common  Shares issued upon due  conversion  of any shares of this Series,  which
contain such legends as the  Corporation  in its  discretion  deems  adequate to
reflect the hold period described in this Section 8.

                  "9. Miscellaneous.

                  "(a) For the purposes hereof:

                           "(i) the term  "outstanding",  when used in reference
                  to shares of this  Series,  shall mean  issued  shares of this
                  Series, excluding shares of this Series called for redemption;
                  and

                           "(ii) the term "subsidiary"  shall mean any company a
                  majority of whose outstanding voting capital stock (other than
                  directors'  qualifying  shares),  at the time as of which  any
                  determination  is being made,  shall be owned by the parent of
                  such company  either  directly or through other  subsidiaries;

                           "(iii)  any  shares of a series or class of shares of
                  the Corporation shall be deemed to rank:

                           or not the dividend rates,  dividend payment dates or
                           redemption or liquidation prices per share thereof be
                           different from those of shares of this Series, if the
                           holders of such shares of a series or class of shares
                           shall be entitled to receipt from the  Corporation of

                           or priority to the holders of shares of this  Series,

                           prices per share  thereof be different  from those of
                           shares of this Series,  if the holders of such shares
                           of a series or class of shares  shall be  entitled to
                           the receipt from the  Corporation  of dividends or of
                           amounts   distributable  upon  liquidation  to  their
                           respective  dividend  rates  or  liquidation  prices,
                           without  preference or priority one over the other as
                           between  the  holders  of such  shares of a series or
                           class of  shares  and the  holders  of shares of this
                           Series; and

                                    "(C)  subordinate  to shares of this Series,

                           dates or redemption or  liquidation  prices per share
                           thereof  be  different  from  those of shares of this
                           Series,  if the rights of the  holders of such shares
                           of a series or class of shares  shall be  subordinate
                           to the rights of the holders of shares of this Series
                           in respect of the  receipt  from the  Corporation  of
                           dividends   and   of   amounts   distributable   upon
                           liquidation,  dissolution  or winding up,  including,
                           without   limitation,   the  Common   Shares  of  the
                           Corporation.

         hereafter amended and supplemented) the provisions  hereof, as the same
         may be amended or supplemented, shall be and remain controlling.

                 TERMS OF SERIES B CONVERTIBLE PREFERRED SHARES
                               (Without Par Value)


     "1. Number and Designation.  The number of shares to constitute this series
shall be  2,500,000  and the  designation  of such shares shall be the "Series B
Convertible Preferred Shares" (hereinafter called "this Series").  The number of
shares  constituting this Series may be decreased from time to time by action of
the Board,  but not below the number of shares of this Series then  outstanding.
All shares of this Series  shall be identical  with each other in all  respects.
The shares of this Series  shall rank senior to the common  shares (the  "Common
Shares")  of the  Corporation  and equal to the Series A  Convertible  Preferred
Shares ("Series A Convertible Shares") as to dividends and upon liquidation,  as
described  below.  Any amounts  herein  referencing  share  prices or numbers of
shares  shall be subject to  appropriate  adjustments  in the event of any stock
splits, consolidations or the like.

     "2. Dividend Rights.

     "(a) Subject to the  provisions of this Section 2, the holders of shares of
this Series shall be entitled to receive, when and as declared by the Board, out
of any funds  legally  available  therefor,  preferential  cumulative  dividends
("Dividends") (i) at a rate per annum per share equal to eight percent (8.0%) of
the Conversion  Price (as hereinafter  defined),  payable as provided in Section
2(b)  hereof,  through  October 31,  2004;  (ii) from  November 1, 2004  through
October 31, 2005; at a rate per annum per share equal to twelve percent  (12.0%)
of the Conversion Price,  payable in U.S.  dollars;  (iii) from November 1, 2005
through October 31, 2006, at a rate per annum per share equal to fifteen percent
(15.0%) of the  Conversion  Price,  payable in U.S.  dollars;  and (iv) from and
after November 1, 2006, at a rate per annum per share equal to eighteen  percent
(18.0%) of the  Conversion  Price,  payable  in U.S.  dollars.  Full  cumulative
Dividends  shall be paid before any dividends  shall be set apart for or paid in
any year upon the Common  Shares or any other  shares  ranking  as to  dividends
junior to this Series  (such Common  Shares and other  shares being

<PAGE>

referred to hereinafter  collectively as "Junior Stock").  Accruals of Dividends
under Section 2(b)(i) shall not bear interest.  All Dividends  declared upon the
shares of this Series shall be declared pro rata per share.

     "(b) (i) No  Dividends  on this Series will be declared  until  October 31,
2000.  At such time, if the  Corporation's  EBTA, as reported in or derived from
the  Corporation's   annual  report  filed  with  the  Securities  and  Exchange
Commission, for the fiscal year ended July 31, 2000, is equal to or greater than
U.S. $0.20  (excluding CFO Costs) per fully diluted Common Share, as measured to
include Common Shares  issuable upon the conversion of the shares of this Series
and the Series A Convertible  Shares but to exclude the Common  Shares  issuable
upon the exercise of the Warburg  Warrants (the "Fully Diluted Common  Shares"),
then the holders of shares of this Series  shall be entitled to receive when and
as declared by the Board out of assets legally available  therefor a Dividend in
respect of the period  beginning on the Initial Issuance Date (as defined below)
and  ending on October  31,  2000,  and each  quarter  thereafter,  in each case
payable in U.S.  dollars,  before any  dividends  shall be set apart for or paid
upon any Junior Stock in any year.  "EBTA" means net income (excluding profit or
loss on disposal of a significant part of the  Corporation's  assets or separate
segment  thereof,  gains  on  restructuring  payables,  gains or  losses  on the
extinguishment of debt, expropriations of property, gains or losses that are the
direct result of a major casualty, or one-time losses resulting from prohibition
under a newly-enacted law or regulation)  before income taxes,  Dividends on the
shares of this Series and the  Corporation's  Series A Convertible  Shares,  and
amortization  of goodwill and  covenants  not to compete.  "CFO Costs" means the
costs, if such person is hired by the Corporation on or before January 31, 2000,
of (i) retaining an executive search firm to hire a chief financial  officer for
the Corporation and (ii)  relocating such person.  "Warburg  Warrants" means the
warrants to purchase 2,000,000 Common Shares issued to Warburg, Pincus Ventures,
L.P. ("Warburg") pursuant to that certain amended and restated warrant agreement
between the Corporation and Warburg dated as of the Initial Issuance Date.

     (ii) If EBTA per Fully Diluted  Common Share for the fiscal year ended July
31, 2000 is less than U.S. $0.20 (excluding CFO Costs),  then Dividends will not
be payable until such time as the Corporation meets the quarterly EBTA

                                      -2-
<PAGE>

targets set forth below for four (4) consecutive fiscal quarters. From and after
such time,  Dividends will be payable quarterly in cash in U.S. dollars,  before
any dividends  shall be set apart for or paid upon any Junior Stock in any year.
If the  Corporation  has not met the quarterly  EBTA targets set forth below for
four (4) consecutive  fiscal quarters by the fiscal quarter ended July 31, 2002,
then Dividends will not be payable on shares of this Series.

     "(c) To the extent  payable  pursuant to Section 2(b) hereof,  Dividends on
this Series shall accrue  quarterly on October 31, January 31, April 30 and July
31 of each year,  beginning  October 31, 1999, and shall be cumulative  from the
date of initial  issuance of the shares of this Series  (the  "Initial  Issuance
Date"),  whether or not earned or declared and whether or not in any fiscal year
there shall be assets,

                                      -3-
<PAGE>

net profits or surplus  legally  available for the payment of such  Dividends in
respect of such fiscal year,  so that if in any fiscal year or years,  Dividends
are not paid upon shares of this Series in the full amounts specified in Section
2(a) hereof,  unpaid Dividends which are payable under Section 2(b) hereof shall
accumulate  as against the holders of the Junior Stock and any sums in any later
years shall be paid to the holders of this Series with respect to any prior year
or years when Dividends were not paid.

     "(d) The record date for the determination of the holders of shares of this
Series who shall be entitled to receive  Dividends  (the "Record Date") shall be
thirty  (30) days prior to any payment  date,  and only the holders of shares of
this  Series of record on the Record  Date  shall be  entitled  to receive  such
Dividends.

     "(e) Dividends payable on shares of this Series for any period other than a
full dividend period shall be computed on the basis of a 360-day year consisting
of twelve  30-day  months.  Any  Dividend  payment made on shares of this Series
shall first be credited  against the earliest  accumulated but unpaid  Dividends
due with respect to the shares of this Series.

     "(f) No dividends shall be declared or paid or set aside for payment on any
share capital of the Corporation  ranking, as to dividends,  on a parity with or
subordinate to the shares of this Series for any period unless full  accumulated
Dividends have been or contemporaneously are declared and paid or declared and a
sum sufficient for the payment  thereof set aside for such payment on the shares
of this Series for all Dividend  periods  terminating on or prior to the date of
payment of such dividends.  When Dividends are not paid in full on the shares of
this  Series and any other  preferred  shares of the  Corporation  ranking  with
respect to payment of dividends on a parity with the shares of this Series,  all
dividends  declared or paid upon shares of this Series and such other  preferred
shares  shall be  declared  and paid pro rata so that the  amount  of  dividends
declared and paid on the shares of this Series and such other  preferred  shares
shall in all cases bear to each other the same ratio that accumulated  dividends
per share (which in the case of noncumulative preferred shares shall not include
any accumulation in respect of unpaid  dividends for prior dividend  periods) on
shares of this Series and such other preferred shares bear to each other. Except
as provided in the preceding  sentence,  unless full accumulated

                                      -4-
<PAGE>

Dividends  have been  paid or  declared  and a sum  sufficient  for the  payment
thereof  set  aside  for  payment,   no  dividends   (other  than  dividends  or
distributions paid in Common Shares, or options, warrants or rights to subscribe
for or purchase  Common  Shares or, in each case,  any other series of shares of
the Corporation ranking subordinate to the shares of this Series as to dividends
and upon  liquidation)  shall be declared and paid or a sum  sufficient  for the
payment thereof set aside for payment or any other distribution declared or made
upon or in respect  of the Common  Shares,  Series A  Convertible  Shares or any
other class of shares of the Corporation  ranking  subordinate to or on a parity
with the shares of this Series as to  dividends or upon  liquidation.  No Common
Shares,  Series A  Convertible  Shares or shares of any other class of shares of
the  Corporation  ranking  subordinate to or on a parity with the shares of this
Series as to dividends or upon liquidation shall be redeemed, purchased, retired
or otherwise  acquired for any  consideration  (and no funds shall be paid to or
made  available for a sinking fund for the redemption of any such share capital)
by the  Corporation  (except by  conversion  into or exchange  for shares of the
Corporation ranking subordinate to the shares of this Series as to dividends and
upon  liquidation  or except with respect to Common Shares that the  Corporation
has  become  obligated  to redeem  prior to the  issuance  of any shares of this
Series upon the occurrence of specified circumstances) unless, in each case, the
full  accumulated  Dividends  in respect of this Series  shall have been paid or
declared  and a sum  sufficient  for the payment  thereof set aside for payment.
Holders of shares of this Series shall not be entitled to any dividend,  whether
payable in cash,  property  or stock,  in excess of the full  Dividends  on such
shares.

     "(g) Upon  conversion  of any shares of this  Series by any holder  thereof
pursuant to Section 7 hereof,  any Dividends  accrued and payable to such holder
shall be forfeited and the Corporation shall have no further  obligation to such
holder of shares of this Series for such accumulated Dividends.

     "3.  Liquidation  Rights.  (a) In the event of any voluntary or involuntary
dissolution, liquidation, or winding up of the affairs of the Corporation, after
payment  or  provision  for  payment of the debts and other  liabilities  of the
Corporation and any  preferential  amounts payable with respect to securities of
the Corporation  ranking prior to the shares of this Series  ("Senior  Preferred
Shares"),  the

                                      -5-
<PAGE>

holders of each share of this  Series  shall be  entitled  to receive out of the
assets of the Corporation available for distribution to shareholders, before any
distribution  of  assets  is made to  holders  of Junior  Stock,  a  liquidating
distribution in an amount equal to the Conversion Rate multiplied by the greater
of (i) the Conversion Price per share of this Series plus an amount equal to any
accrued and unpaid  Dividends,  whether or not declared  (including  accumulated
Dividends),  to and  including  the date of  distribution  or (ii) the per share
amount  distributable to the holders of shares of this Series as if such holders
had converted their shares of this Series into Common Shares pursuant to Section
7 hereof immediately prior to such dissolution, liquidation or winding up of the
affairs  of  the  Corporation  (plus  accumulated  Dividends,   whether  or  not
declared).  Amounts payable  pursuant to clause (i) or (ii) of this Section 3(a)
shall be  distributed  ratably  among the  holders  of shares of this  Series in
proportion  to the number of shares of this Series  held.  After  payment to the
holders of shares of this  Series of the full  amount to which such  holders are
entitled as set forth above,  the holders of shares of this Series shall have no
right or claim to any of the remaining assets of the Corporation.

     "(b) If upon any such dissolution, liquidation or winding up of the affairs
of the  Corporation,  the  assets  of the  Corporation  distributable  among the
holders of shares of this Series and the holders of all other  classes or series
of shares of the Corporation  ranking on a parity with the shares of this Series
shall be  insufficient  to permit the  payment to them of the full  preferential
amounts to which they are entitled, then the entire assets of the Corporation so
to be distributed  shall be  distributed  ratably among the holders of shares of
this  Series and such other  classes or series of shares of the  Corporation  in
proportion  to  the  sum  of  the  accumulated  dividends  and  the  liquidation
preferences per share.

     "(c)  The  sale,   conveyance,   mortgage,   pledge  or  lease  of  all  or
substantially  all  the  assets  of the  Corporation  shall  be  deemed  to be a
liquidation,  dissolution or winding up of the  Corporation for purposes of this
Section 3.

     "4. Optional Redemption.  (a) The shares of this Series may not be redeemed
before the fifth  anniversary  of the Initial  Issuance Date.  Thereafter,  each
share of this Series shall be redeemable  (subject to subsection  4(d) below) at
the option of the  Corporation,  in whole or in

                                      -6-
<PAGE>

part, at the redemption price,  which shall be an amount equal to the Conversion
Rate  multiplied  by the greater of (i) the  Conversion  Price per share of this
Series  plus the amount of any accrued  and unpaid  Dividends  per share of this
Series (including accumulated Dividends,  whether or not declared),  or (ii) the
Fair Market  Value of a share of this Series (as defined  below).  For  purposes
hereof,  the Fair Market Value shall be  determined  by a nationally  recognized
independent  investment  banking firm mutually  agreed to by the Corporation and
the holder of a majority of the shares of this Series  then  outstanding,  whose
determination shall be conclusive.

     "(b)(i)  In case the  Corporation  shall  desire to  exercise  its right to
redeem any shares of this  Series,  it shall give notice of such  redemption  to
holders of the shares of this Series to be redeemed as  hereinafter  provided in
this Section 4(b).

          "(ii) Notice of redemption  shall be given to the holders of shares of
     this Series to be redeemed by mailing  such notice by  first-class  mail to
     their last  addresses as they shall appear upon the register for the shares
     of this Series not less than 120 calendar  days prior to the date fixed for
     redemption.

          "(iii) Each such notice of redemption (A) shall specify the date fixed
     for redemption and the redemption  price at which shares of this Series are
     to be redeemed,  (B) shall state that payment of the  redemption  price for
     the  shares of this  Series to be  redeemed  will be made at the  principal
     executive  offices of the Corporation,  upon  presentation and surrender of
     certificates  representing such shares of this Series, and (C) if less than
     all the shares of this Series are to be redeemed,  shall specify the number
     of shares of this Series held by each  holder to be  redeemed.  In case any
     certificate  representing  shares of this  Series is to be redeemed in part
     only,  the notice of  redemption  which relates to such  certificate  shall
     state the number of shares of this Series  represented by such  certificate
     to be redeemed and shall state that on and after the redemption  date, upon
     surrender of such  certificate,  a new certificate or certificates  for the
     number of shares of this Series  equal to the  unredeemed  portion  thereof
     will be issued.

                                      -7-
<PAGE>

          "(iv) If less than all the shares of this  Series are to be  redeemed,
     the  Corporation  shall effect such  redemption  pro rata among the holders
     thereof  (based on the number of shares of this  Series held on the date of
     notice of redemption).

     "(c) (i) If the giving of notice of redemption shall have been completed as
provided above,  the shares of this Series specified in such notice shall become
redeemable,  and shall be  redeemed by the  Corporation  upon  presentation  and
surrender of the certificate  representing  such shares,  on the date and at the
place stated in such notice at the redemption  price, and on and after such date
fixed for  redemption,  notwithstanding  that any certificate for shares of this
Series  so  called  for  redemption   shall  not  have  been   surrendered   for
cancellation,  unless  there  shall  have  been  a  default  in  payment  of the
redemption  price,  all shares of this  Series  called for  redemption  shall no
longer be deemed to be  outstanding,  and all rights with respect to such shares
of this Series shall forthwith cease and terminate  except only the right of the
holders thereof to receive from the Corporation  the redemption  price,  without
interest, of the shares to be redeemed,  and such shares shall not thereafter be
transferred on the books of the  Corporation or be deemed to be outstanding  for
any purpose whatsoever.

          "(ii) Upon presentation of any certificate representing shares of this
     Series only a portion of which are to be redeemed,  the  Corporation  shall
     immediately  issue,  at its  expense,  a new  certificate  or  certificates
     representing the shares of this Series not redeemed.

     "(d) Except as provided in paragraph (a) above, the Corporation  shall have
no right to redeem  the  shares of this  Series.  Any  shares of this  Series so
redeemed shall be permanently retired, shall no longer be deemed outstanding and
shall not under any circumstances be reissued, and the Corporation may from time
to time take such appropriate corporate action as may be necessary to reduce the
authorized  shares of this Series  accordingly.  Nothing herein  contained shall
prevent or restrict the purchase by the Corporation, from time to time either at
public or private sale, of the whole or any part of the shares of this Series at
such price or prices as the Corporation may determine, subject to the provisions
of applicable law.

     "5. No Mandatory Redemption. The shares of this Series shall not be subject
to mandatory redemption by the Corporation.

     "6. Voting  Rights.  (a) Each issued and  outstanding  share of this Series
shall be  entitled  to the  number  of votes  equal to the  Conversion  Rate (as
adjusted from time to time pursuant to Section 7(a) hereof),  at each meeting of
shareholders of the Corporation with respect to any and all matters presented to
the shareholders of the Corporation for their action or consideration. Except as
provided by law, by the  provisions of paragraph (b) below or by the  provisions
establishing the terms of any other class of preferred stock of the Corporation,
holders of the  shares of this  Series  and of any other  outstanding  preferred
stock,  including without limitation the Series A Convertible Shares, shall vote
together with the holders of Common Shares as a single class.

     (b) In addition to any other rights provided by law, the Corporation  shall
not amend,  alter or repeal the  preferences,  special rights or other powers of
the shares of this Series or any other provision of the Corporation's constating
documents that would adversely affect the rights of the holders of the shares of
this Series, including, without limitation, any increase in the number of shares
of this Series,  without the written consent or affirmative  vote of the holders
of at least 66-2/3% of the then  outstanding  aggregate number of such adversely
affected  shares  of this  Series,  given in  writing  or by vote at a  meeting,
consenting  or  voting  (as the case  may be)  separately  as a class.  For this
purpose,  the  authorization or issuance of any series of preferred stock of the
Corporation  with  preference  or priority  over,  or being on a parity with the
shares of this  Series as to the right to receive  either  dividends  or amounts
distributable  upon  liquidation,  dissolution or winding up of the  Corporation
shall be deemed to adversely affect the shares of this Series.

     "7.  Conversion.  (a) (i) Each share of this Series may be converted at any
time, at the option of the holder thereof,  in the manner hereinafter  provided,
into fully-paid and nonassessable Common Shares, provided,  however, that on any
redemption of any shares of this Series or any  liquidation of the  Corporation,
the right of  conversion  shall  terminate  at the close of business on the full
business  day next  preceding  the date  fixed  for such  redemption  or for the
payment of any amounts distributable

                                      -9-
<PAGE>

on liquidation to the holders of the shares of this Series. The number of Common
Shares of the  Corporation  into which each share of this Series is  convertible
(the  "Conversion  Rate") shall equal,  for each one share of this Series,  such
number of Common Shares equal to (I)(A) the sum of (1) U.S. $10,000,000 plus (2)
the sum of any  Adjustment  Amounts for any fiscal  periods  preceding  the last
completed fiscal period (the sum of the amounts in (A)(1) and (A)(2),  the "Base
Factor") plus (B) the Adjustment  Amount,  if any, for the last completed fiscal
period,  divided by (II) the  conversion  price for shares of this  Series  (the
"Conversion  Price"),  divided by (III) 2,500,000.  The initial  Conversion Rate
shall be one  Common  Share for each one share of this  Series  surrendered  for
conversion,  representing an initial  Conversion  Price (for purposes of Section
7(g)) of U.S. $4.00 per share of the Corporation's Common Shares. The applicable
Conversion Rate and Conversion  Price from time to time in effect are subject to
adjustment as hereinafter provided.

          (ii) For purposes hereof, the term "Adjustment  Amount" shall mean (a)
     $800,000 as of October 31, 2000,  (b) two percent (2.0%) of the Base Factor
     in effect at such time, for any adjustment  occurring from November 1, 2000
     through  October 31, 2004;  (c) three percent  (3.0%) of the Base Factor in
     effect at such time,  for any  adjustment  occurring  from November 1, 2004
     through October 31, 2005; (d) three and  three-quarters  percent (3.75%) of
     the Base Factor in effect at such time, for any  adjustment  occurring from
     November  1, 2005  through  October  31,  2006;  and (e) four and  one-half
     percent  (4.5%)  of the  Base  Factor  in  effect  at  such  time,  for any
     adjustment  occurring from and after November 1, 2006;  provided,  however,
     that in the event that EBTA per Fully  Diluted  Common Share for the fiscal
     year ended July 31, 2000 is greater than or equal to U.S. $0.20  (excluding
     CFO Costs),  then the Adjustment Amount for all purposes shall be zero; and
     provided,  further,  that in the event the EBTA per  Fully  Diluted  Common
     Share for the  fiscal  year  ended  July 31,  2000 is less than U.S.  $0.20
     (excluding CFO Costs) and the Corporation  meets the quarterly EBTA targets
     set forth below for four (4) consecutive  fiscal quarters  thereafter,  the
     Adjustment  Amount shall be zero in respect of any fiscal  quarter ended on
     or after  the last  day of such  fourth  consecutive  fiscal  quarter.  For
     purposes of paragraph (i) above and clauses (b)-(e) of this paragraph (ii),
     the Adjustment  Amount shall be determined and the Conversion Rate shall be
     adjusted as of the end of each

                                      -10-
<PAGE>

     fiscal  quarter.  Any  conversion of shares of this Series shall be made at
     the  Conversion  Rate in effect as of the end of the fiscal  quarter  ended
     immediately prior to the date of such conversion.

          (iii) As of October 31, 2000, the Conversion  Price will be reduced by
     the  Per  Share  Valuation   Adjustment,   if  any.  "Per  Share  Valuation
     Adjustment"  means the Valuation  Adjustment  divided by the sum of (i) the
     total number of issued and  outstanding  Common  Shares as of September 30,
     1999 plus (ii) the total number of Shares into which the outstanding Series
     A Convertible  Preferred Shares are convertible plus (iii) the total number
     of Shares into which the outstanding  convertible  notes of the Corporation
     are  convertible  as of  September  30, 1999 plus (iv) the total  number of
     Shares into which the outstanding  shares of this Series are convertible as
     of October 31, 2000.  "Valuation  Adjustment" means the Reserve  Deficiency
     multiplied by a

                                      -11-
<PAGE>

     factor of 7.  "Reserve  Deficiency"  means  the  amount,  if any,  by which
     $4,736,000  exceeds the amounts  collected by the  Corporation on or before
     July 31, 2000 for services  performed on or before July 31, 1999.  No later
     than October 31, 2000, the Chief Financial Officer of the Corporation shall
     certify as to the Reserve  Deficiency  to each  record  holder of shares of
     this  Series.  At the  request of any  record  holder of the shares of this
     Series,  the Corporation shall cause the Reserve  Deficiency to be verified
     by an audit performed by an  internationally-recognized  independent public
     accounting firm.

          "(b) Whenever the  Conversion  Price or the  Conversion  Rate shall be
     adjusted  as  provided  in  Section  7(a)(i) or Section  7(g)  hereof,  the
     Corporation  shall  forthwith  file  at  each  office  designated  for  the
     conversion of the shares of this Series, a statement,  signed by any of the
     Chairman of the Board,  the President,  any Vice President or the Treasurer
     of the Corporation,  showing in reasonable  detail the facts requiring such
     adjustment.  The  Corporation  shall also cause a notice  setting forth any
     such adjustments to be sent by mail, first class,  postage prepaid, to each
     record  holder of shares of this Series at his or its address  appearing on
     the stock register.  If such notice relates to an adjustment resulting from
     an event referred to in paragraph 7(g)(vii),  such notice shall be included
     as part of the  notice  required  to be  mailed  and  published  under  the
     provisions of paragraph 7(g)(vii) hereof.

          "(c) The right of  conversion  shall be exercised by the holder by the
     surrender  of the  certificates  representing  shares of this  Series to be
     converted to the  Corporation  at any time during normal  business hours at
     the office or agency then  maintained by it for the conversion of shares of
     this Series (the "Conversion Office"), accompanied by written notice to the
     Corporation of such holder's election to convert and, if so required by the
     Corporation or any conversion agent, by an instrument of transfer,  in form
     satisfactory to the Corporation and to any conversion  agent, duly executed
     by the registered holder or by such holder's duly authorized attorney,  and
     transfer  tax stamps or funds  therefor,  if  required  pursuant to Section
     7(k).

          "(d) As promptly as practicable  after the surrender for conversion of
     one or more  certificates  representing  any  shares of this  Series in the
     manner  provided  in  Section  7(c) and the  payment  in cash of any amount
     required by the provisions of Section 7(k), the Corporation will deliver or

                                      -12-
<PAGE>

     cause to be delivered at the Conversion Office to or upon the written order
     of the holder of such shares,  a certificate or  certificates  representing
     the number of full Common Shares issuable upon such  conversion,  issued in
     such name or names as such  holder may  direct,  subject to any  applicable
     contractual   restrictions  and  any  restrictions  imposed  by  applicable
     securities  laws.  Such  conversion  shall  be  deemed  to have  been  made
     immediately prior to the close of business on the date of such surrender of
     certificates  representing  shares  of this  Series  in  proper  order  for
     conversion, and all rights of the holder of such shares as a holder of such
     shares shall cease at such time, and the person or persons in whose name or
     names the  certificates  for such Common  Shares are to be issued  shall be
     treated  for all  purposes  as having  become the record  holder or holders
     thereof at such time;  provided,  however,  that any such  surrender on any
     date when the stock transfer books of the Corporation shall be closed shall
     constitute  the person or  persons in whose name or names the  certificates
     for such  Common  Shares are to be issued as the  record  holder or holders
     thereof for all purposes  immediately prior to the close of business on the
     next succeeding day on which such stock transfer books are opened.

          "(e) Upon  conversion in the manner provided in this Section 7 of only
     a  portion  of the  number  of  shares  of  this  Series  represented  by a
     certificate so surrendered for conversion,  the Corporation shall issue and
     deliver or cause to be  delivered at the  Conversion  Office to or upon the
     written  order  of  the  holder  of  the  certificate  so  surrendered  for
     conversion,  at  the  expense  of the  Corporation,  a new  certificate  or
     certificates  representing the number of shares of this Series representing
     the unconverted  portion of the certificate so surrendered,  issued in such
     name  or  names  as such  holder  may  direct,  subject  to any  applicable
     contractual   restrictions  and  any  restrictions  imposed  by  applicable
     securities laws.

          "(f) All shares of this Series which shall have been  surrendered  for
     conversion as herein  provided  shall no longer be deemed to be outstanding
     and all rights with respect to such shares,  including the rights,  if any,
     to receive notices and to vote,  shall forthwith cease and terminate except
     only the right of the holder  thereof to receive  Common Shares in exchange
     therefor.  Any shares of this  Series so  converted  shall be  retired  and
     canceled and shall not be reissued,  and the  Corporation  may from time to

                                      -13-
<PAGE>

     time  take  such  appropriate  action as may be  necessary  to  reduce  the
     authorized shares of this Series accordingly.

     "(g) Anti-Dilution Provisions.

     (i) In order to  prevent  dilution  of the  right  granted  hereunder,  the
Conversion  Price shall be subject to adjustment from time to time in accordance
with this paragraph  7(g)(i).  At any given time the  Conversion  Price shall be
that  dollar  (or  part of a  dollar)  amount  the  payment  of  which  shall be
sufficient at the given time to acquire one Common Share of the Corporation upon
conversion  of shares of this Series.  Upon each  adjustment  of the  Conversion
Price  pursuant to this Section 7(g),  the  registered  holder of shares of this
Series shall thereafter be entitled to acquire upon exercise,  at the Conversion
Price  resulting  from such  adjustment,  the  number  of  Common  Shares of the
Corporation obtainable by multiplying the Conversion Price in effect immediately
prior to such  adjustment  by the  number  of  shares  of  Common  Shares of the
Corporation  acquirable  immediately  prior to such  adjustment and dividing the
product thereof by the Conversion  Price  resulting from such a adjustment.  For
purposes  of this  Section  7(g),  the term  "Number  of  Common  Shares  Deemed
Outstanding" at any given time shall mean the sum of (x) the number of shares of
the  Corporation's  Common Shares  outstanding  at such time,  (y) the number of
Common Shares of the Corporation  issuable  assuming  conversion at such time of
all  outstanding  shares  of  the  Corporation's  other  series  of  convertible
preferred  stock, if any, and (z) the number of Common Shares of the Corporation
deemed to be  outstanding at such time under  subparagraphs  7(g)(ii)(1) to (8),
inclusive.  For all purposes  hereof,  the term "Market Price," as to the Common
Shares as of any specified date, shall mean: (i) if the Common Shares are listed
or  admitted  for  trading  on one or more  United  States  national  securities
exchanges,  the daily  closing  price  for the  Common  Shares on the  principal
exchange in the United States on which the Common Shares are listed; (ii) if the
Common  Shares  are not listed or  admitted  for  trading  on any United  States
national securities  exchange,  the daily closing price for the Common Shares on
the Nasdaq National or Nasdaq Small-Cap Market  ("Nasdaq");  (iii) if the Common
Shares are not  listed or  admitted  for  trading  on a United  States  national
securities  exchange or on Nasdaq,  the daily closing price of the Common Shares
on the principal  stock exchange in Canada on which the Common Shares are listed
(expressed in United States  dollars based upon the noon buying rate in New York
City for cable transfers in Canadian  dollars as certified for customs  purposes
by the  Federal  Reserve  Bank of New York);  (iv) if the Common  Shares are not
listed or admitted to trading on any United States national or Canadian

                                      -14-
<PAGE>

national  securities  exchange or on Nasdaq, the average of the reported bid and
asked  prices on the trading  day  preceding  such date in the  over-the-counter
market as furnished by the National Quotation Bureau,  Inc., or, if such firm is
not then engaged in the business of reporting  such prices,  as furnished by any
member of the National  Association of Securities Dealers,  Inc. selected by the
Corporation;  or (v) if the Common  Shares are not publicly  traded,  the Market
Price for such day shall be the fair market value thereof  determined jointly by
the  Corporation  and the holder of a majority of the shares of this Series then
outstanding;  provided,  however,  that if such  parties  are  unable  to  reach
agreement  within  a  reasonable  period  of time,  the  Market  Price  shall be
determined  in good faith by the  independent  investment  banking firm selected
jointly by the  Corporation  and the holder of a majority  of the shares of this
Series  then  outstanding  or,  if  that  selection  cannot  be made  within  an
additional 15 days, by an  independent  investment  banking firm selected by the
American Arbitration Association in accordance with its rules.

     (ii) Except as provided in paragraph  7(g)(iii) or 7(g)(vi)  below,  if and
whenever on or after the Initial  Issuance Date, the Corporation  shall issue or
sell, or shall in accordance with subparagraphs  7(g)(ii)(1) to (8),  inclusive,
be deemed to have  issued or sold  (such  issuance  or sale,  whether  actual or
deemed, the "Triggering  Transaction") any Common Shares for a consideration per
share less than,

          (I)  (if the  Common  Shares  are not  traded  on the New  York  Stock
     Exchange,  the American Stock Exchange or the Nasdaq  National  Market) the
     Conversion Price in effect  immediately  prior to the time of such issuance
     or sale,  then forthwith upon such  Triggering  Transaction  the Conversion
     Price shall,  subject to subparagraphs (1) to (8) of this Section 7(g)(ii),
     be reduced to the  Conversion  Price  (calculated to the nearest tenth of a
     cent)  determined  by  dividing:  (i) an amount equal to the sum of (x) the
     product   derived  by  multiplying  the  Number  of  Common  Shares  Deemed
     Outstanding  immediately  prior  to  such  Triggering  Transaction  by  the
     Conversion  Price  then in  effect,  plus  (y) the  consideration,  if any,
     received  by  the   Corporation   upon   consummation  of  such  Triggering
     Transaction,  by (H) an amount equal to the sum of (x) the Number of Common
     Shares Deemed Outstanding  immediately prior to such Triggering Transaction
     plus (y) the  number of Common  Shares  issued  (or  deemed to be issued in
     accordance  with  subparagraphs  7(g)(ii)(l) to (8)) in connection with the
     Triggering Transaction; or

                                      -15-
<PAGE>

          (II) (if the Common Shares are traded on the New York Stock  Exchange,
     the  American  Stock  Exchange or the Nasdaq  National  Market) the average
     Market Price for the ten trading days  immediately  preceding such issuance
     or sale,  then forthwith upon such Triggering  Transaction,  the Conversion
     Price shall,  subject to subparagraphs (1) to (8) of this Section 7(g)(ii),
     be reduced to the  Conversion  Price  (calculated to the nearest tenth of a
     cent) determined by multiplying the Conversion Price in effect  immediately
     prior  to the  time of  such  Triggering  Transaction  by a  fraction,  the
     numerator  of which  shall be the sum of (x) the  Number of  Common  Shares
     Deemed Outstanding immediately prior to such Triggering Transaction and (y)
     the number of Common Shares which the aggregate  consideration  received by
     the  Corporation  upon such  Triggering  Transaction  would purchase at the
     average  Market Price for the ten trading days  immediately  preceding such
     Triggering Transaction, and the denominator of which shall be the Number of
     Common  Shares  Deemed   Outstanding   immediately  after  such  Triggering
     Transaction.

          For purposes of determining the adjusted  Conversion  Price under this
paragraph 7(g)(ii),  the following  subsections (1) to (8), inclusive,  shall be
applicable:

               (1) In case the Corporation at any time shall in any manner grant
          (whether  directly or by assumption in an  amalgamation  or otherwise)
          any rights to  subscribe  for or to  purchase,  or any options for the
          purchase  of,  Common   Shares  or  any  stock  or  other   securities
          convertible  into or  exchangeable  for Common  Shares (such rights or
          options  being  herein  called   "Options"  and  such  convertible  or
          exchangeable  stock or  securities  being herein  called  "Convertible
          Securities"),  whether or not such  Options or the right to convert or
          exchange any such Convertible Securities are immediately  exercisable,
          and the price per share for which the Common  Shares are issuable upon
          exercise, conversion or exchange (determined by dividing (x) the total
          amount,   if  any,  received  or  receivable  by  the  Corporation  as
          consideration  for the granting of such  Options,  plus the  aggregate
          amount of additional consideration payable to the Corporation upon the
          exercise of all such Options,  plus, in the case of such Options which
          relate to Convertible  Securities,  the aggregate amount of additional
          consideration,  if  any,  payable  upon  the  issue  or  sale  of such
          Convertible Securities and upon the conversion or exchange thereof,

                                      -16-
<PAGE>

          by (y) the total  maximum  number of Common  Shares  issuable upon the
          exercise  of  such  Options  or the  conversion  or  exchange  of such
          Convertible Securities) shall be less than the average Market Price in
          effect for the ten trading days  immediately  prior to the time of the
          granting of such  Options (if the Common  Shares are traded on the New
          York  Stock  Exchange,  the  American  Stock  Exchange  or the  Nasdaq
          National Market) or the Conversion Price in effect  immediately  prior
          to the time of the granting of such Options (if the Common  Shares are
          not traded on the New York Stock Exchange, the American Stock Exchange
          or the  Nasdaq  National  Market),  then the total  maximum  number of
          Common  Shares  issuable  upon the exercise of such Options or, in the
          case of Options for  Convertible  Securities,  upon the  conversion or
          exchange  of such  Convertible  Securities,  shall  (as of the date of
          granting of such Options) be deemed to be outstanding and to have been
          issued  and sold by the  Corporation  for such  price  per  share.  No
          adjustment  of the  Conversion  Price  shall be made  upon the  actual
          issuance of such Common Shares or such Convertible Securities upon the
          exercise of such Options, except as otherwise provided in subparagraph
          (3) below.

               (2) In case the Corporation at any time shall in any manner issue
          (whether directly or by assumption in an amalgamation or otherwise) or
          sell any Convertible Securities, whether or not the rights to exchange
          or convert thereunder are immediately  exercisable,  and the price per
          share for which Common  Shares are issuable  upon such  conversion  or
          exchange  (determined  by dividing  (x) the total  amount  received or
          receivable by the Corporation as  consideration  for the issue or sale
          of  such  Convertible   Securities,   plus  the  aggregate  amount  of
          additional consideration,  if any, payable to the Corporation upon the
          conversion or exchange  thereof,  by (y) the total  maximum  number of
          Common  Shares  issuable  upon the  conversion or exchange of all such
          Convertible Securities) shall be less than the average Market Price in
          effect for the ten trading days immediately  prior to the time of such
          issue or sale (if the  Common  Shares are traded on the New York Stock

                                      -17-
<PAGE>

          Exchange,  the American Stock Exchange or the Nasdaq National  Market)
          or the  Conversion  Price in effect  immediately  prior to the time of
          such  issue or sale (if the  Common  Shares  are not traded on the New
          York  Stock  Exchange,  the  American  Stock  Exchange  or the  Nasdaq
          National  Market),  then the total  maximum  number  of Common  Shares
          issuable  upon   conversion  or  exchange  of  all  such   Convertible
          Securities  shall  (as of the  date  of the  issue  or  sale  of  such
          Convertible  Securities) be deemed to be outstanding  and to have been
          issued  and sold by the  Corporation  for such  price  per  share.  No
          adjustment  of the  Conversion  Price  shall be made  upon the  actual
          issuance of such Common Shares upon exercise of the rights to exchange
          or convert  under such  Convertible  Securities,  except as  otherwise
          provided in subparagraph (3) below.

               (3) If the purchase price provided for in any Options referred to
          in subparagraph  (1), the additional  consideration,  if any,  payable
          upon the conversion or exchange of any Convertible Securities referred
          to in  subparagraphs  (1) or (2), or the rate at which any Convertible
          Securities referred to in subparagraph (1) or (2) are convertible into
          or exchangeable for Common Shares shall change at any time (other than
          under or by reason of provisions  designed to protect against dilution
          of the type  set  forth  in  paragraphs  7(g)(ii)  or  7(g)(iv)),  the
          Conversion  Price in effect at the time of such change shall forthwith
          be readjusted to the Conversion  Price which would have been in effect
          at  such  time  had  such  Options  or  Convertible  Securities  still
          outstanding  provided  for such  changed  purchase  price,  additional
          consideration  or  rate,  as the case  may be,  at the time  initially
          granted,  issued or sold.  If the purchase  price  provided for in any
          Option   referred   to  in   subparagraph   (1)  or   the   additional
          consideration,  if any, payable upon the conversion or exchange of any
          Convertible Securities referred to in subparagraphs (1) or (2), or the
          rate at which any Convertible  Securities referred to in subparagraphs
          (1) or (2) are  convertible  into or  exchangeable  for Common Shares,
          shall be  reduced at any time  under or by reason of  provisions  with
          respect thereto designed to protect against dilution,  then in case of
          the delivery of Common  Shares upon the exercise of any such Option or
          upon  conversion  or exchange of any such  Convertible  Security,  the
          Conversion  Price then in effect hereunder shall forthwith be adjusted
          to such respective  amount as would have been obtained had such Option
          or Convertible Security never been issued as to such Common Shares and
          had  adjustments  been made upon the

                                      -18-
<PAGE>

          issuance of the Common Shares delivered as aforesaid, but only if as a
          result  of  such  adjustment  the  Conversion  Price  then  in  effect
          hereunder is hereby reduced.

               (4) On the  expiration  of any Option or the  termination  of any
          right  to  convert  or  exchange  any  Convertible   Securities,   the
          Conversion Price then in effect hereunder shall forthwith be increased
          to the Conversion Price which would have been in effect at the time of
          such   expiration  or  termination  had  such  Option  or  Convertible
          Securities,  to the  extent  outstanding  immediately  prior  to  such
          expiration or termination, never been issued.

               (5) In case any Options  shall be issued in  connection  with the
          issue  or  sale  of  other  securities  of the  Corporation,  together
          comprising one integral transaction in which no specific consideration
          is  allocated  to such  Options by the parties  thereto,  such Options
          shall be deemed to have been issued without consideration.

               (6) In case any Common Shares,  Options or Convertible Securities
          shall be issued  or sold or  deemed  to have  been  issued or sold for
          cash, the  consideration  received  therefor shall be deemed to be the
          amount  received by the  Corporation  therefor  (before  deduction for
          expenses or  underwriters'  discounts or  commissions  related to such
          issue or sale).  In case any Common  Shares,  Options  or  Convertible
          Securities  shall be issued  or sold for a  consideration  other  than
          cash, the amount of the consideration  other than cash received by the
          Corporation  shall  be  the  fair  value  of  such   consideration  as
          determined in good faith by the Board of Directors of the Corporation.

               (7) In case the Corporation  shall declare a dividend or make any
          other  distribution upon the share capital of the Corporation  payable
          in Common Shares,  Options,  or Convertible  Securities,  then in such
          case any Common Shares, Options or Convertible Securities, as the case
          may be, issuable in payment of such dividend or distribution  shall be
          deemed to have been issued or sold without consideration.

               (8)  For  purposes  of  this  paragraph  7(g)(ii),  in  case  the
          Corporation  shall take a record of the  holders

                                      -19-
<PAGE>

          of its Common Shares for the purpose of entitling  them (x) to receive
          a dividend or other distribution payable in Common Shares,  Options or
          in Convertible Securities,  or (y) to subscribe for or purchase Common
          Shares, Options or Convertible Securities, then such record date shall
          be  deemed to be the date of the  issue or sale of the  Common  Shares
          deemed  to have  been  issued  or sold  upon the  declaration  of such
          dividend or the making of such other  distribution  or the date of the
          granting of such right or  subscription  or purchase,  as the case may
          be.

          (iii) In the event the  Corporation  shall declare a dividend upon the
Common  Shares  (other  than a  dividend  payable  in Common  Shares  covered by
subparagraph  7(g)(ii)(7))  payable  otherwise  than out of  earnings  or earned
surplus,  determined  in  accordance  with U.S.  generally  accepted  accounting
principles,   including  the  making  of  appropriate  deductions  for  minority
interests,   if  any,  in  subsidiaries  (herein  referred  to  as  "Liquidating
Dividends"),  then,  as soon as possible  after the  conversion of any shares of
this Series, the Corporation shall, subject to applicable law, pay to the person
converting  such shares of this Series an amount equal to the aggregate value at
the  time of such  exercise  of all  Liquidating  Dividends  (including  but not
limited to the Common  Shares  which  would have been issued at the time of such
earlier  exercise  and all other  securities  which  would have been issued with
respect  to such  Common  Shares  by reason of stock  splits,  stock  dividends,
amalgamations or reorganizations,  or for any other reason). For the purposes of
this  paragraph  7(g)(iii),  a dividend  other than in cash shall be  considered
payable out of earnings or earned  surplus only to the extent that such earnings
or earned surplus are charged an amount equal to the fair value of such dividend
as determined in good faith by the Board.

          (iv) In case the Corporation  shall at any time subdivide  (other than
by  means  of  a  dividend   payable  in  Common  Shares  covered  by  paragraph
7(g)(ii)(7)) its outstanding  Common Shares into a greater number of shares, the
Conversion  Price  in  effect  immediately  prior to such  subdivision  shall be
proportionately reduced, and, conversely,  in case the outstanding Common Shares
of the  Corporation  shall be  combined  into a smaller  number of  shares,  the
Conversion  Price  in  effect  immediately  prior to such  combination  shall be
proportionately increased.

          (v) If any capital  reorganization  or  reclassification  of the share
capital of the  Corporation,  or amalgamation  of the  Corporation  with another
corporation,  or the sale of all or

                                      -20-
<PAGE>

substantially all of its assets to another corporation shall be effected in such
a way that  holders  of  Common  Shares  shall be  entitled  to  receive  stock,
securities,  cash or other  property  with  respect to or in exchange for Common
Shares,  then,  as  a  condition  of  such   reorganization,   reclassification,
amalgamation  or sale,  lawful and adequate  provision shall be made whereby the
holders of shares of this  Series  shall have the right to acquire  and  receive
upon conversion of the shares of this Series,  which right shall be prior to the
rights of the  holders of Junior  Stock (but after and  subject to the rights of
holders of Senior Preferred Shares,  if any), such shares of stock,  securities,
cash or other  property  issuable  or  payable  (as part of the  reorganization,
reclassification,  amalgamation or sale) with respect to or in exchange for such
number of  outstanding  Common  Shares  of the  Corporation  as would  have been
received upon  conversion of the shares of this Series at the  Conversion  Price
then in effect.  The Corporation will not effect any such  amalgamation or sale,
unless prior to the  consummation  thereof the  amalgamated  corporation  or the
corporation  purchasing such assets shall assume by written instrument mailed or
delivered  to the  holders of the shares of this  Series at the last  address of
each such holder  appearing on the books of the  Corporation,  the obligation to
deliver to each such holder such  shares of stock,  securities  or assets as, in
accordance  with the  foregoing  provisions,  such  holder  may be  entitled  to
receive. If a purchase,  tender or exchange offer is made to and accepted by the
holders of more than 50% of the  outstanding  Common Shares of the  Corporation,
the Corporation shall not effect any amalgamation or sale with the person having
made such offer or with any Affiliate (as defined below) of such person,  unless
prior to the consummation of such amalgamation or sale the holders of the shares
of this Series shall have been given a reasonable  opportunity  to then elect to
receive  upon the  conversion  of the  shares of this  Series  either the stock,
securities  or assets then  issuable  with  respect to the Common  Shares of the
Corporation or the stock,  securities or assets,  or the  equivalent,  issued to
previous  holders  of the  Common  Shares in  accordance  with such  offer.  For
purposes  hereof,  the term  "Affiliate"  with respect to any given person shall
mean any person  controlling,  controlled  by or under  common  control with the
given person.

          (vi) The provisions of this Section 7(g) shall not apply to any Common
Shares issued, issuable or deemed outstanding under subparagraphs 7(g)(ii)(1) to
(8) inclusive: (i) to any person pursuant to any stock option, stock purchase or
similar plan or arrangement  for the benefit of employees of the

                                      -21-
<PAGE>

Corporation  or its  subsidiaries  in effect  on the  Initial  Issuance  Date or
thereafter  adopted by the Board of Directors of the Corporation,  (ii) pursuant
to options,  warrants and conversion rights in existence on the Initial Issuance
Date,  (iii) upon exercise of the Warburg  Warrants or (iv) on conversion of the
shares of this Series or the sale of any additional shares of this Series.

          (vii) In the event that:

               (1) the  Corporation  shall  declare any cash  dividend  upon its
     Common Shares, or

               (2) the  Corporation  shall  declare any dividend upon its Common
     Shares payable in stock or make any special dividend or other  distribution
     to the holders of its Common Shares, or

               (3) the Corporation  shall offer for subscription pro rata to the
     holders of its Common Shares any additional shares of stock of any class or
     other rights, or

               (4) there shall be any capital reorganization or reclassification
     of the share  capital of the  Corporation,  including  any  subdivision  or
     combination  of its  outstanding  Common  Shares,  or  amalgamation  of the
     Corporation  with,  or sale of all or  substantially  all of its assets to,
     another corporation, or

               (5)  there  shall  be a  voluntary  or  involuntary  dissolution,
     liquidation or winding up of the Corporation;

then, in connection with such event,  the Corporation  shall give to the holders
of the shares of this Series:

               (A)  at least twenty (20) days' prior written  notice of the date
                    on which  the  books  of the  Corporation  shall  close or a
                    record  shall be taken for such  dividend,  distribution  or
                    subscription  rights  or for  determining  rights to vote in
                    respect  of  any  such   reorganization,   reclassification,
                    amalgamation, sale, dissolution,  liquidation or winding up;
                    and

               (B)  in the  case of any such  reorganization,  reclassification,
                    amalgamation, sale, dissolution,  liquidation or winding up,
                    at least twenty (20)

                                      -22-
<PAGE>

                    days' prior  written  notice of the date when the same shall
                    take place.

Such notice in accordance with the foregoing  clause (A) shall also specify,  in
the case of any such dividend,  distribution or subscription rights, the date on
which the holders of Common Shares shall be entitled thereto, and such notice in
accordance  with the  foregoing  clause (B) shall also specify the date on which
the holders of Common  Shares shall be entitled to exchange  their Common Shares
for  securities  or  other  property   deliverable  upon  such   reorganization,
reclassification, amalgamation, sale, dissolution, liquidation or winding up, as
the case may be. Each such  written  notice  shall be given by first class mail,
postage  prepaid,  addressed  to the holders of the shares of this Series at the
last address of each such holder appearing on the books of the Corporation.

                  (viii)  If at any time or from  time to time on or  after  the
Initial Issuance Date, the Corporation  shall grant,  issue or sell any Options,
Convertible  Securities or rights to purchase  property (the "Purchase  Rights")
pro rata to the record holders of the Common Shares of the  Corporation and such
grants,  issuances  or sales do not result in an  adjustment  of the  Conversion
Price under paragraph 7(g)(ii) hereof, then each holder of shares of this Series
shall be entitled to acquire  (within  thirty (30) days after the later to occur
of the initial  exercise date of such Purchase  Rights or receipt by such holder
of the notice concerning  Purchase Rights to which such holder shall be entitled
under paragraph 7(g)(vii)) and upon the terms applicable to such Purchase Rights
either:

                    (A) the  aggregate  Purchase  Rights which such holder could
                    have  acquired  if it had held the  number of Common  Shares
                    acquirable   upon   conversion  of  shares  of  this  Series
                    immediately  before  the  grant,  issuance  or  sale of such
                    Purchase  Rights;  provided that if any Purchase Rights were
                    distributed  to holders of Common Shares without the payment
                    of additional  consideration by such holders,  corresponding
                    Purchase  Rights  shall  be  distributed  to the  exercising
                    holders  of the  shares of this  Series as soon as  possible
                    after such  exercise and it shall not be  necessary  for the
                    exercising holder of the shares of this Series  specifically
                    to request delivery of such rights; or

                                      -23-
<PAGE>

                    (B) in the event that any such  Purchase  Rights  shall have
                    expired or shall expire prior to the end of said thirty (30)
                    day  period,  the  number of Common  Shares or the amount of
                    property  which such holder  could have  acquired  upon such
                    exercise  at the  time or times  at  which  the  Corporation
                    granted, issued or sold such expired Purchase Rights.

                    (ix) If any event occurs as to which,  in the opinion of the
Board,  the  provisions  of this Section 7(g) are not strictly  applicable or if
strictly  applicable  would not fairly  protect the rights of the holders of the
shares of this Series in accordance with the essential  intent and principles of
such  provisions,  then the Board shall make an adjustment in the application of
such provisions,  in accordance with such essential intent and principles, so as
to protect such rights as aforesaid,  but in no event shall any adjustment  have
the effect of increasing the Conversion Price as otherwise  determined  pursuant
to  any of the  provisions  of  this  Section  7(g)  except  in  the  case  of a
combination of shares of a type  contemplated in paragraph  7(g)(iv) and then in
no event to an amount larger than the Conversion  Price as adjusted  pursuant to
paragraph 7(g)(iv).

                    "(h) No  fractional  Common  Shares shall be issued upon the
               conversion  of  any  share  or  shares  of  this  Series.  If any
               fractional  interest  in a Common  Share  would,  except  for the
               provisions  of  this  Section  7(h),  be  deliverable   upon  the
               conversion of any share or shares of this Series, the Corporation
               shall in lieu of delivering the fractional  Common Share therefor
               satisfy such fractional interest by payment to the holder of such
               surrendered  share or shares of this  Series of an amount in cash
               equal  (computed to the nearest cent) to the current market value
               of such fractional interest,  computed on the basis of the Market
               Price  of the  Common  Shares  on the  date of  such  conversion,
               provided,   however,   that  no  amount  shall  be  paid  by  the
               Corporation to such holder of less than U.S. $5.00.

                    "(i)  The  Corporation  shall  be  entitled  to  effect  the
               mandatory conversion,  in whole or in part, of the shares of this
               Series in accordance  with this Section 7 if all of the following
               conditions   ("Mandatory   Conversion   Conditions")   have  been
               satisfied as of the date of the notice described below:

                    (a) the  Common  Shares  are  traded  on the New York  Stock
               Exchange,  the  American  Stock  Exchange or the Nasdaq  National
               Market at a Market Price greater than U.S. $8.00 per Common

                                      -24-
<PAGE>

               Share on each of the 10  consecutive  trading days preceding such
               date; and (b) the  Corporation's  EBTA for the three  consecutive
               fiscal  quarters  preceding  such date, as reported in or derived
               from the Corporation's quarterly or annual reports filed with the
               Securities and Exchange Commission,  shall have averaged at least
               U.S. $0.35 per Fully Diluted Common Share per fiscal quarter. All
               references  to per share  amounts or prices  with  respect to the
               above  conditions   shall  be  appropriately   adjusted  for  any
               subdivision,  consolidation,  or  reclassification  of the Common
               Shares.

                    Upon such  mandatory  conversion,  each share of this Series
               subject to such conversion  shall be converted into Common Shares
               at the then effective  Conversion Price for such shares.  In case
               the Corporation shall desire to exercise the right to convert all
               or, as the case may be, any shares of this  Series in  accordance
               with the right to do so, it shall  provide  notice to the holders
               of the  shares of this  Series  to be  converted  as  hereinafter
               provided in this Section 7(i)."

                         "(i) A  notice  of  conversion  shall  be  given to the
               holders of shares of this  Series to be  converted  by mailing by
               first-class  mail to their last  addresses  as they shall  appear
               upon the  register  for  shares of this  Series not less than 120
               calendar days prior to the date fixed for conversion.

                         "(ii) Each such notice of conversion  (A) shall specify
               the date fixed for  conversion  and the  number of Common  Shares
               issuable  to the  holder  of a share  of this  Series  upon  such
               conversion,  (B)  shall  state  the  offices  or  agencies  to be
               maintained by the Corporation for the purpose of such conversion,
               upon presentation and surrender of such shares of this Series and
               (C) if  less  than  all  the  shares  of  this  Series  are to be
               converted, shall specify the number of shares of this Series held
               by  each  holder,  and the  serial  numbers  of the  certificates
               thereof,  to be converted.  In case any certificate  representing
               shares of this Series is to be converted in part only, the notice
               of conversion which relates to such  certificate  shall state the
               number of shares of this Series  represented by such  certificate
               to be converted and shall state that on and after the  conversion
               date,  upon surrender of such  certificate,  a new certificate or
               certificates  for a number of shares of this Series  equal to the
               unconverted portion thereof will be issued.

                    "(j) The  Corporation  will at all  times  reserve  and keep
               available,  solely for the  purposes  of the  issuance  of Common
               Shares upon  conversion  of the shares of this  Series,  the full
               number of Common Shares as shall be issuable upon the  conversion
               of all such outstanding shares of this Series.

                    The Corporation  will endeavor to comply with all securities
               laws  regulating  the offer and  delivery  of Common  Shares upon
               conversion  of the shares of this Series and,  that if any Common
               Shares  required to be reserved for purposes of conversion of the
               shares  hereunder  require  registration  with or approval of any
               governmental  authority  under  any U.S.  (federal  or  state) or
               Canadian  law or the laws of any  province or territory of Canada
               before such Common Shares may be validly issued or delivered upon
               conversion,   the   Corporation   will,  in  good  faith  and  as
               expeditiously as possible,  endeavor to secure such  registration
               or approval, as the case may be.

Agreement,  including those  evidenced by a certificate or  certificates  issued
upon division,  exchange or substitution  pursuant to this Agreement;  (iii) the
term "Warrant Price" shall mean the price per Share at which Shares shall at any
time be  purchasable  upon  exercise of the  Warrants,  such price to equal U.S.
$6.75, subject to adjustment pursuant to Section 6 hereof,  provided that if the
Series A Amendment  Filing Date has not  occurred on or prior to March 31, 2000,
then from and after March 31, 2000, such price shall equal U.S.  $4.00,  subject
to  adjustment  pursuant  to  Section  6  hereof;  and (iv) the term  "Series  A
Amendment  Filing  Date"  shall  mean the date  upon  which  the  amendment  and
restatement  of the  terms  of the  Series  A  Convertible  Shares,  in the form
attached to the Securities Purchase Agreement as Exhibit B, shall have occurred,
as  preceded  by the  passing  of  resolutions  by a  majority  of not less than
two-thirds of the votes cast by the holders of the Common  Shares,  the Series A
Convertible Shares and Series B Convertible  Shares of the Company,  each voting
separately  as a  class,  as  evidenced  by (1) a  duly  executed  report  of an
inspector  of election,  (2) a copy of the  articles of  amendment  amending the
terms  of the  Series  A  Convertible  Shares,  certified  by the  registrar  of
Corporations  of the  Yukon  Territory  and (3) an  opinion  of  counsel  to the
Company,  addressed to the Investor,  in the form attached  hereto as Exhibit 4,
and such other  documentation as the Investor may reasonably  request;  provided
that no Series A Amendment  Filing Date shall occur after March 31, 2000.  Terms
which are  capitalized but not defined herein shall have the same meanings as in
the Securities Purchase  Agreement.  Any amounts herein referencing share prices
or numbers of shares shall be subject to appropriate adjustments in the event of
any stock splits, consolidations or the like.

         For the purpose of defining  the terms and  provisions  of the Warrants
and the  respective  rights and  obligations  thereunder,  the  Company  and the
Warrantholder, for value received, hereby agree as follows:

         Section 1.  Restrictions on Transfer and Form of Warrants.

hypothecated or otherwise  transferred by the Warrantholder  without the express
written consent of the Company,  such consent not to be  unreasonably  withheld.
Any  transferee  permitted  under this Section 1.2 shall  acquire  title to such

         1.4.  Legends on Warrants  and Common  Shares.  The  Warrants,  and the
Shares issuable upon the exercise  thereof,  have not been registered  under the

the Warrants shall bear the following legend:

                  "THE WARRANTS REPRESENTED BY THIS CERTIFICATE,  AND THE COMMON
                  SHARES ISSUABLE UPON EXERCISE OF SUCH WARRANTS,  HAVE NOT BEEN
                  REGISTERED  UNDER THE UNITED STATES  SECURITIES ACT OF 1933 OR
                  THE  SECURITIES  LAWS OF ANY STATE OF THE UNITED STATES OR ANY
                  PROVINCE OF CANADA. SUCH WARRANTS MAY NOT BE SOLD, OFFERED FOR
                  SALE,   ASSIGNED,   EXCHANGED,   PLEDGED  OR  HYPOTHECATED  OR
                  OTHERWISE  TRANSFERRED,  IN ANY MANNER, AND SUCH COMMON SHARES
                  MAY NOT BE OFFERED FOR SALE, SOLD,  PLEDGED OR HYPOTHECATED OR
                  TRANSFERRED IN THE ABSENCE OF SUCH  REGISTRATION OR AN OPINION
                  OF COUNSEL,  REASONABLY  SATISFACTORY TO THE COMPANY,  THAT AN
                  EXEMPTION FROM SUCH  REGISTRATION  IS AVAILABLE.  THE WARRANTS
                  REPRESENTED  BY THIS  CERTIFICATE  MAY NOT BE TRADED IN CANADA
                  EXCEPT AS PERMITTED BY RELEVANT CANADIAN SECURITIES LAWS."

Each certificate for the Shares shall bear the following legend:

                  "THE COMMON SHARES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT
                  BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933
                  OR THE  SECURITIES  LAWS OF ANY STATE OF THE UNITED  STATES OR
                  ANY  PROVINCE  OF  CANADA  AND  MAY  NOT  BE  SOLD,  ASSIGNED,
                  EXCHANGED  OR

                  OTHERWISE TRANSFERRED,  IN THE ABSENCE OF SUCH REGISTRATION OR
                  AN OPINION OF COUNSEL, REASONABLY SATISFACTORY TO THE COMPANY,
                  THAT AN EXEMPTION  FROM SUCH  REGISTRATION  IS AVAILABLE  THIS
                  CERTIFICATE MAY NOT CONSTITUTE 'GOOD DELIVERY' IN SATISFACTION
                  OF  A  TRADE  MADE  ON  A  STOCK  EXCHANGE  IN  CANADA.   THIS
                  CERTIFICATE IS NOT TRANSFERABLE IN CANADA UNTIL MARCH 30, 2000
                  EXCEPT   PURSUANT  TO  AN   EXEMPTION   FROM  THE   PROSPECTUS
                  REQUIREMENTS    CONTAINED   IN   THE   APPLICABLE   SECURITIES
                  LEGISLATION."

         Any certificate  issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon completion
of  a  public  distribution  pursuant  to a  registration  statement  under  the
Securities Act of the Common Shares represented  thereby) shall also bear a like
legend unless, in the opinion of counsel reasonably satisfactory to the Company,
the  securities   represented   thereby  need  no  longer  be  subject  to  such
restrictions.

         Section 2.  Term of Warrants; Exercise of Warrants.

                  (a) Subject to the terms of this Agreement,  the Warrantholder
shall  have the  right,  at any time and from  time to time  during  the  period
commencing at 9:00 a.m.,  Pacific Time, on October 1, 1999,  (the  "Commencement
Date")  and  ending  at 5:00  p.m.,  Pacific  Time,  on  October  1,  2004  (the
"Termination  Date") to purchase from the Company up to the number of fully paid
and nonassessable  Shares which the Warrantholder may at the time be entitled to
purchase  pursuant  to this  Agreement,  upon  surrender  to the  Company at its
principal  office of the  certificates  evidencing the Warrants to be exercised,
with the purchase form, in the form attached hereto as Exhibit 2, duly completed
and  signed,  and upon  payment  to the  Company  of an  amount  (the  "Exercise
Payment")  equal to the Warrant  Price  multiplied by the number of Shares being
purchased  pursuant to such exercise,  payable in cash, by certified or official
bank check, or by wire transfer.

                  (b) At any time  subsequent  to the first  anniversary  of the
Commencement  Date,  in lieu of  exercising  the Warrants as provided in Section
2(a) above,  and subject to all  applicable  law and all  applicable  regulatory
approvals, limitations and restrictions, the Warrantholder may elect to receive,
without any cash payment,  a number of Shares equal to the value (as  determined
below) of any or all of the Warrants held of record by

                                      -4-
<PAGE>

the Warrantholder,  upon surrender to the Company at its principal office of the
certificates  evidencing such Warrants, with the attached cashless exercise form
attached  hereto as Exhibit 3 duly  completed  and  signed,  in which  event the
Company shall issue to the  Warrantholder  a number of Shares computed using the
following formula:

                  X = Y(A-B)
                                        A

where

                  X = the number of Common Shares to be issued  pursuant to this
                      Section 2(b).

                  Y = the number of Common Shares  issuable upon exercise of the
                      surrendered Warrants.

                  A = the average of the Market  Prices of the Common Shares for
                      the sixty (60)  calendar  days  immediately  preceding the
                      date  upon   which   the   certificates   evidencing   the
                      surrendered  Warrants  are  received by the Company at its
                      principal office.

                  B = the Warrant Price on such date.

         For all purposes of this  Agreement  the term "Market  Price" as of any
specified  date shall mean:  (i) if the Common Shares are listed or admitted for
trading on one or more United States national  securities  exchanges,  the daily
closing  price for the Common  Shares on the  principal  exchange  in the United
States on which the Common Shares are listed;  (ii) if the Common Shares are not
listed  or  admitted  for  trading  on any  United  States  national  securities

or admitted for trading on a United States  national  securities  exchange or on
Nasdaq,  the daily closing  price of the Common  Shares on the  principal  stock
exchange in Canada on which the Common  Shares are listed  (expressed  in United
States  dollars  based  upon the noon  buying  rate in New York  City for  cable
transfers in Canadian  dollars as certified for customs  purposes by the Federal
Reserve Bank of New York);  (iv) if the Common Shares are not listed or admitted
to  trading  on any United  States  national  or  Canadian  national  securities
exchange or on Nasdaq,  the average of the  reported bid and asked prices on the

Quotation Bureau,  Inc., or, if such firm is not then engaged in the business of
reporting such prices, as furnished by any member of the National Association of
Securities  Dealers,  Inc. selected by the Company;  or (y) if the Common Shares
are not publicly traded,  the Market Price for such day shall be the fair market
value thereof determined jointly by the Company and the Warrantholder; provided,
however,  that if such parties are unable to reach agreement within a reasonable
period  of time,  the  Market  Price  shall be  determined  in good  faith by an
independent  investment  banking  firm  selected  jointly by the Company and the
Warrantholder or, if that selection cannot be made within an additional 15 days,
by an independent  investment banking firm selected by the American  Arbitration
Association in accordance with its rules.

                  (c)  The Company may, at any time, elect to force the exercise
of the  Warrants  by the  Warrantholder  subject to the terms of this  Agreement

         trading days immediately preceding the date of such election; and

                       (iii) The Company's net income  (excluding profit or loss
         on disposal of a significant  part of the Company's  assets or separate
         segment thereof,  gains on restructuring  payables,  gains or losses on
         the extinguishment of debt, expropriations of property, gains or losses
         that are the direct  result of a major  casualty,  or  one-time  losses
         resulting from  prohibitions  under a newly-enacted  law or regulation)
         for the three  consecutive  fiscal quarters ended  immediately prior to
         the date of such election, as reported in or derived from its quarterly
         or annual reports filed with the  Securities  and Exchange  Commission,
         before  income taxes,  dividends on the Company's  Series A Convertible
         Preferred   Shares   and   Series  B   Convertible   Preferred   Shares
         (collectively,  the "Convertible  Shares") and amortization of goodwill
         and covenants  not to compete for such  quarterly  periods,  shall have
         averaged at least U.S.  $0.35 per fully diluted Common Share per fiscal
         quarter, provided, however,

                                      -6-
<PAGE>

         that in making  such  calculation,  the  Common  Shares  issuable  upon
         exercise of the Warrants  shall be excluded but Common Shares  issuable
         upon the conversion of the Convertible Shares shall not.

The foregoing  conditions (i), (ii) and (iii) shall  hereinafter be collectively
referred to as the "Triggering  Conditions." All references to per share amounts
or prices  with  respect to the  Triggering  Conditions  shall be  appropriately
adjusted for any stock splits, consolidations or the like.

         The  Company  shall  give the  Warrantholder  written  notice  that the
Triggering  Conditions have been satisfied and that the Company intends to force
the exercise of the Warrants.  In this event,  the Termination Date shall be the
date ten (10) business days after such notice shall be effectively  delivered to
the Warrantholder as provided in Section 10 of this Agreement.

         In the event of a forced exercise of Warrants  pursuant to this Section
2(c), in lieu of exercising the Warrants as provided in Section 2(a) above,  and
subject  to  all  applicable  law  and  all  applicable   regulatory  approvals,
limitations and restrictions,  the  Warrantholder may elect to receive,  without
any cash payment, a number of Shares equal to the value (as determined below) of
any or all of the Warrants held of record by the  Warrantholder,  upon surrender
to the  Company at its  principal  office of the  certificates  evidencing  such
Warrants,  with the attached  cashless  exercise form thereof duly completed and
signed,  in which event the Company shall issue to the holder a number of Shares
computed using the formula set forth in Section 2(b) except the term "A" in such
formula, the Market Price of the Common Shares, shall be calculated based on the
ten (10) trading days  immediately  preceding the date on which the certificates
evidencing the surrendered Warrants are received by the Company at its principal
offices.

         (d) Upon the  surrender  of  Warrant  certificates  and  payment of the
Exercise  Payment  (in cash,  except in the event of a cashless  exercise),  the
Company,  at its  expense,  shall  issue  and  cause  to be  delivered  with all
reasonable  dispatch,  and in any event within ten (10) days thereafter,  to the
Warrantholder  a certificate  or  certificates  for the number of full Shares so
acquired upon the exercise of the Warrant,  together with cash in respect of any
fractional  Shares  otherwise  issuable  upon  such  surrender,   determined  in
accordance  with Section 7 hereof.  Such  certificate or  certificates  shall be
deemed to have been issued, and the Warrantholder shall be deemed to have become
a holder of record of such  Shares,  as of the date of surrender of the

                                      -7-
<PAGE>

Warrants being exercised and (in the case of exercise  pursuant to Section 2(a))
payment  of  the  Exercise  Payment  notwithstanding  that  the  certificate  or
certificates representing such securities shall not actually have been delivered
or that the stock  transfer  books of the  Company  shall  then be  closed.  The
Warrants  shall be exercisable  at the election of the  Warrantholder  either in
full  or  from  time  to time in  part  and,  in the  event  that a  certificate
evidencing  Warrants  is  exercised  in  respect of fewer than all of the Shares
specified  therein at any time prior to the Termination  Date, a new certificate
evidencing the remaining portion of the Warrants shall be issued by the Company.

         Section 3.  Payment of Taxes.  The Company  will pay all  transfer  and
stamp  taxes and fees,  if any,  attributable  to the  initial  issuance  of the
Warrants or the issuance of Shares upon exercise of the Warrants.

         Section 4. Mutilated or Missing  Warrants.  In case the  certificate or
certificates  evidencing  any  Warrants  shall be  mutilated,  lost,  stolen  or
destroyed,  the Company  shall,  at the request of the  affected  Warrantholder,
issue and deliver in exchange and substitution for and upon  cancellation of the
mutilated  certificate or  certificates,  or in lieu of and substitution for the
certificate or certificates lost, stolen or destroyed, a new Warrant certificate
or certificates of like tenor and  representing an equivalent right or interest,
but only upon receipt of evidence reasonably  satisfactory to the Company of the
loss, theft, destruction or mutilation of such Warrant and, if requested, at the
cost  and  expense  of  the  Warrantholder  (in  the  case  of  loss,  theft  or
destruction),  an  unsecured  bond of  indemnity  in form and amount  reasonably
satisfactory to the Company.  Such  substitute  Warrant  certificate  shall also
comply with such other reasonable regulations as the Company may prescribe.

         Section 5. Reservation of Common Shares.  There has been reserved,  and
the  Company  shall at all times  keep  reserved  and  available  so long as any
Warrants remain outstanding, out of its authorized share capital, such number of
Shares as shall be subject to purchase  under all  outstanding  Warrants.  Every
transfer  agent for the  Common  Shares  and  other  securities  of the  Company
issuable  upon the  exercise  of Warrants  will be  irrevocably  authorized  and
directed at all times to reserve  such number of  authorized  Common  Shares and
other securities as shall be requisite for such purposes.  The Company will keep
a copy of this  Agreement  on file with  every  transfer  agent  for the  Common
Shares.  The Company will supply every such  transfer  agent with duly  executed
stock and other certificates,  as appropriate, for

                                      -8-
<PAGE>

such purpose and will provide or otherwise  make available any cash which may be
payable as provided in Section 7 hereof.

         Section 6. Adjustment of Number and Kind of Securities.  The number and
kind of securities purchasable upon the exercise of the Warrants and the Warrant
Price shall be subject to  adjustment  from time to time upon the  happening  of
certain events, as follows:

         6.1.  Anti-Dilution  Provisions  And  Other  Adjustments.  In  order to
prevent  dilution of the rights  granted  hereunder,  the Warrant Price shall be
subject to adjustment  from time to time in accordance with this Section 6. Upon
each   adjustment  of  the  Warrant  Price  pursuant  to  this  Section  6,  the
Warrantholder  shall  thereafter  be entitled to acquire upon  exercise,  at the
Warrant Price resulting from such adjustment, the number of Shares obtainable by
multiplying the Warrant Price in effect  immediately prior to such adjustment by
the  number  of  Shares  acquirable  immediately  prior to such  adjustment  and
dividing  the  product   thereof  by  the  Warrant  Price  resulting  from  such
adjustment.

              (a)  Adjustment  for Issue or Sale of  Common  Shares at Less than
Specified  Prices.  Except as  provided  in  Sections  6.3 or 6.5 below,  if and
whenever on or after the date hereof the Company  shall issue or sell,  or shall
in accordance with subparagraphs  6.1(a)(1) to (8), inclusive, be deemed to have
issued or sold (such issuance or sale,  whether actual or deemed,  a "Triggering
Transaction") any Common Shares for a consideration per share less than

              (I) (if the  Common  Shares  are not  traded on the New York Stock
         Exchange,  the American Stock Exchange or the Nasdaq  National  Market)
         U.S.  $6.75 then  forthwith  upon such issue or sale the Warrant  Price
         shall,  subject to subparagraphs  (1) to (8) of this Section 6.1(a), be
         reduced to the Warrant  Price  (calculated  to the  nearest  tenth of a
         cent) determined by dividing: (i) an amount equal to the sum of (x) the
         product  derived  by  multiplying  the Number of Common  Shares  Deemed
         Outstanding  immediately  prior to such  Triggering  Transaction by the
         Warrant  Price  then in  effect,  plus (y) the  consideration,  if any,
         received  by  the  Company  upon   consummation   of  such   Triggering
         Transaction,  by (ii) an amount  equal to the sum of (x) the  Number of
         Common Shares Deemed  Outstanding  immediately prior to such Triggering
         Transaction  plus (y) the number of shares of Common  Stock  issued (or
         deemed to be issued in accordance with subparagraphs  6.1(a)(1) to (8))
         in connection with the Triggering Transaction; or

                                      -9-
<PAGE>

              (II) (if the  Common  Shares  are  traded  on the New  York  Stock
         Exchange,  the American Stock Exchange or the Nasdaq  National  Market)
         the average Market Price for the ten trading days immediately preceding
         such issuance or sale, then forthwith upon such Triggering Transaction,
         the Warrant Price shall,  subject to  subparagraphs  (1) to (8) of this
         Section  6.1(a),  be reduced to the Warrant  Price  (calculated  to the
         nearest tenth of a cent) determined by multiplying the Warrant Price in
         effect immediately prior to the time of such Triggering  Transaction by
         a fraction,  the  numerator of which shall be the sum of (x) the Number
         of  Common  Shares  Deemed   Outstanding   immediately  prior  to  such
         Triggering  Transaction  and (y) the number of Common  Shares which the
         aggregate  consideration  received by the Company upon such  Triggering
         Transaction  would  purchase  at the average  Market  Price for the ten
         trading days immediately preceding such Triggering Transaction, and the
         denominator  of which  shall be the  Number  of  Common  Shares  Deemed
         Outstanding immediately after such Triggering Transaction.

         For  purposes  of this  Section 6, the term  "Number  of Common  Shares
Deemed  Outstanding"  at any given  time shall mean the sum of (i) the number of
Common  Shares  outstanding  at such time,  and (ii) the number of Common Shares
deemed to be outstanding under  subparagraphs  6.1(a)(1) to (8),  inclusive,  at
such time.

         For  purposes of  determining  the  adjusted  Warrant  Price under this
Section  6.1(a),  the  following  subsections  (1) to (8),  inclusive,  shall be
applicable:

              (1) In case the  Company  at any time  shall in any  manner  grant
         (whether directly or by assumption in an amalgamation or otherwise) any
         rights to subscribe for or to purchase, or any options for the purchase
         of, Common Shares or any stock or other securities  convertible into or
         exchangeable  for Common  Shares (such  rights or options  being herein
         called  "Options"  and  such  convertible  or  exchangeable   stock  or
         securities being herein called  "Convertible  Securities"),  whether or
         not  such  Options  or the  right  to  convert  or  exchange  any  such
         Convertible Securities are immediately  exercisable,  and the price per
         share  for  which  the  Common  Shares  are  issuable  upon   exercise,
         conversion or exchange (determined by dividing (x) the total amount, if
         any,  received or  receivable by the Company as  consideration  for the
         granting  of  such  Options,  plus  the  minimum  aggregate  amount  of
         additional  consideration  payable to the Company  upon the exercise of
         all such  Options,  plus,  in the case of such Options  which relate to
         Convertible  Securities,  the

                                      -10-
<PAGE>

         minimum aggregate amount of additional  consideration,  if any, payable
         upon the  issue  or sale of such  Convertible  Securities  and upon the
         conversion  or exchange  thereof,  by (y) the total  maximum  number of
         Common  Shares  issuable  upon  the  exercise  of such  Options  or the
         conversion or exchange of such  Convertible  Securities)  shall be less
         than the  average  Market  Price in  effect  for the ten  trading  days
         immediately  prior to the time of the  granting  of such Option (if the
         Common Shares are traded on The New York Stock  Exchange,  The American
         Stock  Exchange or The National  Nasdaq  Market) or U.S.  $6.75 (if the
         Common  Shares  are not  traded  on The New York  Stock  Exchange,  The
         American Stock Exchange,  or the Nasdaq National Market) then the total
         maximum  amount of Common  Shares  issuable  upon the  exercise of such
         Options,  or, in the case of Options for Convertible  Securities,  upon
         the conversion or exchange of such Convertible Securities, shall (as of
         the date of granting of such Options) be deemed to be  outstanding  and
         to have been  issued and sold by the  Company for such price per share.
         No  adjustment of the Warrant Price shall be made upon the actual issue
         of such Common Shares or such Convertible  Securities upon the exercise
         of such  Options,  except as  otherwise  provided in  subparagraph  (3)
         below.

              (2) In case the  Company  at any time  shall in any  manner  issue
         (whether  directly or by assumption in an amalgamation or otherwise) or
         sell any Convertible Securities,  whether or not the rights to exchange
         or convert  thereunder are immediately  exercisable,  and the price per
         share for which Common  Shares are  issuable  upon such  conversion  or
         exchange  (determined  by  dividing  (x) the total  amount  received or
         receivable  by the  Company as  consideration  for the issue or sale of
         such  Convertible  Securities,  plus the  minimum  aggregate  amount of
         additional  consideration,  if any,  payable  to the  Company  upon the
         conversion  or exchange  thereof,  by (y) the total  maximum  number of
         Common  Shares  issuable  upon the  conversion  or exchange of all such
         Convertible  Securities) shall be less than the average Market Price in
         effect for the ten trading days  immediately  prior to the time of such
         issue or sale (if the  Common  Shares  are traded on The New York Stock
         Exchange,  The American Stock Exchange,  or The Nasdaq National Market)
         or U.S.  $6.75 (if the  Common  Shares  are not  traded on The New York
         Stock  Exchange,  The American Stock  Exchange,  or The Nasdaq National
         Market),  then the total maximum number of Common Shares  issuable upon
         conversion or exchange of all such Convertible  Securities shall (as of
         the date of the

                                      -11-
<PAGE>

         issue  or  sale  of  such  Convertible  Securities)  be  deemed  to  be
         outstanding  and to have been  issued and sold by the  Company for such
         price per share.  No adjustment of the Warrant Price shall be made upon
         the actual issue of such Common  Shares upon  exercise of the rights to
         exchange  or  convert  under  such  Convertible  Securities,  except as
         otherwise provided in subparagraph (3) below.

              (3) If the purchase price provided for in any Options  referred to
         in subparagraph (1), the additional consideration, if any, payable upon
         the conversion or exchange of any Convertible Securities referred to in
         subparagraphs  (1) or  (2),  or  the  rate  at  which  any  Convertible
         Securities  referred to in subparagraph (1) or (2) are convertible into
         or exchangeable  for Common Shares shall change at any time (other than
         under or by reason of provisions  designed to protect against  dilution
         of the type set forth in Section 6.1 (a) or (b)),  the Warrant Price in
         effect at the time of such change shall  forthwith be readjusted to the
         Warrant  Price  which  would  have been in effect at such time had such
         Options or Convertible  Securities still outstanding  provided for such
         changed purchase price, additional consideration or conversion rate, as
         the case may be, at the time initially granted,  issued or sold. If the
         purchase price provided for in any Option  referred to in  subparagraph
         (1) or the rate at which  any  Convertible  Securities  referred  to in
         subparagraphs  (1) or (2)  are  convertible  into or  exchangeable  for
         Common  Shares,  shall be  reduced  at any time  under or by  reason of
         provisions with respect thereto  designed to protect against  dilution,
         then in case of the delivery of Common  Shares upon the exercise of any
         such Option or upon  conversion  or  exchange  of any such  Convertible
         Security, the Warrant Price then in effect hereunder shall forthwith be
         adjusted to such respective amount as would have been obtained had such
         Option or  Convertible  Security  never been  issued as to such  Common
         Shares and had  adjustments  been made upon the  issuance of the Common
         Shares  delivered  as  aforesaid,  but  only  if as a  result  of  such
         adjustment  the  Warrant  Price  then in  effect  hereunder  is  hereby
         reduced.

              (4) On the  expiration  of any  Option or the  termination  of any
         right to convert or exchange any  Convertible  Securities,  the Warrant
         Price then in effect  hereunder  shall  forthwith  be  increased to the
         Warrant  Price  which  would  have  been in  effect at the time of such
         expiration or termination had such Option or Convertible Securities, to
         the  extent

                                      -12-
<PAGE>

         outstanding immediately prior to such expiration or termination,  never
         been issued.

              (5) In case any  Options  shall be issued in  connection  with the
         issue or sale of other securities of the Company,  together  comprising
         one  integral  transaction  in  which  no  specific   consideration  is
         allocated to such Options by the parties thereto, such Options shall be
         deemed to have been issued without consideration.

              (6) In case any Common Shares,  Options or Convertible  Securities
         shall be issued or sold or deemed to have been issued or sold for cash,
         the  consideration  received  therefor shall be deemed to be the amount
         received by the Company therefor. In case any Common Shares, Options or
         Convertible  Securities  shall be  issued  or sold for a  consideration
         other  than  cash,  the  amount of the  consideration  other  than cash
         received by the Company  shall be the fair value of such  consideration
         as  determined  in good faith by the Board of Directors of the Company.
         In case any Common Shares,  Options or Convertible  Securities shall be
         issued in connection  with any  amalgamation in which the Company is an
         amalgamating corporation, the amount of consideration therefor shall be
         deemed  to be the fair  value of such  portion  of the net  assets  and
         business of the other  corporation which is a party to the amalgamation
         as shall be attributed by the Board of Directors of the Company in good
         faith to such Common Shares, Options or Convertible Securities,  as the
         case may be.

              (7) In case the Company shall declare a dividend or make any other
         distribution  upon the  stock of the  Company  payable  in  Options  or
         Convertible  Securities,  then in such case any Options or  Convertible
         Securities, as the case may be, issuable in payment of such dividend or
         distribution  shall be  deemed  to have  been  issued  or sold  without
         consideration.

              (8) For purposes of this Section 6.1(a), in case the Company shall
         take a record of the  holders of its Common  Shares for the  purpose of
         entitling them (x) to receive a dividend or other distribution  payable
         in Common  Shares,  Options  or in  Convertible  Securities,  or (y) to
         subscribe  for  or  purchase  Common  Shares,  Options  or  Convertible
         Securities, then such record date shall be deemed to be the date of the
         issue or sale of the Common  Shares  deemed to have been issued or sold
         upon the  declaration  of such  dividend  or the  making of such  other
         distribution  or the

                                      -13-
<PAGE>

         date of the granting of such right or subscription or purchase,  as the
         case may be.

              (b) In case the Company  shall (i) pay a dividend in Common Shares
or make a distribution in Common Shares or (ii) subdivide its outstanding Common
Shares,  the Warrant Price in effect  immediately  prior to such  subdivision or
dividend shall be  proportionately  reduced by the same ratio as the dividend or
subdivision.  In case the  Company  shall at any time  combine  its  outstanding
Common Shares, the Warrant Price in effect immediately prior to such combination
shall be  proportionately  increased by the same ratio as the  combination.  Any
adjustment  made  pursuant to this  subsection  6.1 (b) shall  become  effective
immediately on the effective date of such event  retroactive to the record date,
if any, for such event.

              (c)  Whenever  the number of Common  Shares  purchasable  upon the
exercise of Warrants is adjusted as herein provided,  the Company shall cause to
be promptly  delivered  to the  Warrantholder  notice of such  adjustment  and a
certificate  of the chief  financial  officer of the Company  setting  forth the
number of Common Shares purchasable upon the exercise of the Warrants after such
adjustment,  the Warrant Price that will be effective after such  adjustment,  a
brief  statement of the facts  requiring such  adjustment and the computation by
which  such  adjustment  was  made.  If such  notice  relates  to an  adjustment
resulting  from an event referred to in Section 8, such notice shall be included
as  part  of the  notice  required  to be  delivered  and  published  under  the
provisions of Section 8 hereof.

         6.2. No Adjustment for Dividends. Except as provided in this Section 6,
no adjustment  to the Warrants or any provision or condition  thereof in respect
of any dividends or distributions  out of earnings shall be made during the term
of the Warrants or upon the exercise of Warrants.

         6.3. Dividends Not Paid Out of Earnings or Earned Surplus. In the event
the  Company  shall  declare a dividend  upon the Common  Shares  (other  than a
dividend  payable in Common  Shares)  payable  otherwise than out of earnings or
earned  surplus,  determined in accordance  with generally  accepted  accounting
principles,   including  the  making  of  appropriate  deductions  for  minority
interests,   if  any,  in  subsidiaries  (herein  referred  to  as  "Liquidating
Dividends"),  then, as soon as possible after the exercise of this Warrant,  the
Company shall pay to the person  exercising  such Warrant an amount equal to the
aggregate  value  at the  time of such  exercise  of all  Liquidating  Dividends
(including  but not limited to the Common Shares which would have been issued

                                      -14-
<PAGE>

at the time of such earlier  exercise and all other  securities which would have
been issued with respect to such Common Shares by reason of stock splits,  stock
dividends,  amalgamations or reorganizations,  or for any other reason). For the
purposes  of this  subsection  6.3,  a  dividend  other  than in cash  shall  be
considered  payable out of earnings  or earned  surplus  only to the extent that
such earnings or earned surplus are charged an amount equal to the fair value of
such  dividend  as  determined  in good faith by the Board of  Directors  of the
Company.

         6.4. Reclassification, Amalgamation, etc. If any capital reorganization
or  reclassification of the share capital of the Company, or amalgamation of the
Company with another corporation, or the sale of all or substantially all of its
assets to another  corporation  shall be effected in such a way that  holders of
Common  Shares  shall be entitled to receive  stock,  securities,  cash or other
property with respect to or in exchange for Common Shares,  then, as a condition
of such  reorganization,  reclassification,  amalgamation  or sale,  lawful  and
adequate provision shall be made whereby the Warrantholder  shall have the right
to acquire  and receive  upon  exercise  of this  Warrant  such shares of stock,
securities,  cash  or  other  property  issuable  or  payable  (as  part  of the
reorganization,  reclassification,  amalgamation  or sale) with respect to or in
exchange for such number of outstanding  Shares as would have been received upon
exercise of this Warrant at the Warrant  Price then in effect.  The Company will
not effect  any such  amalgamation  or sale,  unless  prior to the  consummation
thereof the amalgamated  corporation or the  corporation  purchasing such assets
shall assume by written  instrument mailed or delivered to the Warrantholder the
obligation to deliver to such holder such shares of stock,  securities or assets
as, in accordance with the foregoing provisions,  such holder may be entitled to
purchase. If a purchase, tender or exchange offer is made to and accepted by the
holders of more than 50% of the  outstanding  Common Shares of the Company,  the
Company  shall not effect any  amalgamation  or sale with the person having made
such  offer  or  with  any  Affiliate  of  such  person,  unless  prior  to  the
consummation  of such  amalgamation  or sale the  Warrantholder  shall have been
given a  reasonable  opportunity  to then elect to receive  upon the exercise of
this Warrant  either the stock,  securities or assets then issuable with respect
to the Common Shares of the Company or the stock,  securities or assets,  or the
equivalent,  issued to previous  holders of the Common Shares in accordance with
such offer.  For purposes hereof the term  "Affiliate" with respect to any given
person shall mean any person controlling,  controlled by or under common control
with  the  given  person.  In  the  event  of  a

                                      -15-
<PAGE>

merger  described in Section  368(a)(2)(E) of the Internal  Revenue Code of 1986
(or any successor provision), in which the Company is the surviving corporation,
the right to purchase  Shares upon exercise of the Warrants  shall  terminate on
the date of such merger and thereupon  the Warrants  shall become null and void,
but only if the  controlling  corporation  (after  such  event)  shall  agree to
substitute for the Warrants its warrants entitling the Warrantholder to purchase
the kind and amount of shares and other  securities  and property which it would
have been entitled to receive had the Warrants been exercised  immediately prior
to such merger.  Any such  agreements  referred to in this  subsection 6.3 shall
provide  for  adjustments,  which  shall  be as  nearly  equivalent  as  may  be
practicable to the adjustments provided for in this Section 6, and shall contain
substantially the same terms,  conditions and provisions as are contained herein
immediately  prior to such event.  The  provisions of this  subsection 6.4 shall
similarly apply to successive amalgamations, sales or conveyances.

         6.5. No Adjustment for Exercise of Certain Options,  Warrants, Etc. The
provisions  of this  Section  6 shall  not apply to any  Common  Shares  issued,
issuable or deemed outstanding under  subparagraphs  6.1(a)(1) to (8) inclusive:
(i) to any person  pursuant to any stock option,  stock purchase or similar plan
or  arrangement  for the benefit of employees,  consultants  or directors of the
Company or its subsidiaries in effect on the date hereof or hereafter adopted by
the Board of Directors of the Company, or (ii) pursuant to options, warrants and
conversion  rights in existence on the date hereof,  including  the  Convertible
Shares.

         6.6. Grant Issue or Sale of Options, Convertible Securities, or Rights.
If at any time or from time to time on or after the date of this Agreement,  the
Company shall grant, issue or sell any Options, Convertible Securities or rights
to purchase  property (the "Purchase  Rights") pro rata to the record holders of
any class of share capital of the Company and such grants, issuances or sales do
not result in an adjustment of the Warrant  Price under Section  6.1(a)  hereof,
then the  Warrantholder  shall be entitled to acquire  (within  thirty (30) days
after the later to occur of the initial exercise date of such Purchase Rights or
receipt by the Warrantholder of the notice  concerning  Purchase Rights to which
the  Warrantholder  shall be  entitled  under  Section  8) and  upon  the  terms
applicable to such Purchase Rights either:

              (a) the aggregate  Purchase Rights which the  Warrantholder  could
         have  acquired  if it had held the  number  of Shares  acquirable  upon
         exercise of this Warrant

                                      -16-
<PAGE>

         immediately  before the grant issuance or sale of such Purchase Rights;
         provided  that  if  any  Purchase   Rights  were   distributed  to  the
         Warrantholder  of Common  Shares  without  the  payment  of  additional
         consideration by such holders,  corresponding  Purchase Rights shall be
         distributed to the  Warrantholder as soon as possible after exercise of
         this  Warrant  and it  shall  not be  necessary  for the  Warrantholder
         specifically to request delivery of such rights; or

              (b) in the event that any such Purchase  Rights shall have expired
         or shall  expire  prior to the end of said thirty (30) day period,  the
         number of Shares or the  amount  of  property  which the  Warrantholder
         could have  acquired  upon such  exercise at the time or times at which
         the Company granted, issued or sold such expired Purchase Rights.

         6.7.  Nominal  Value of Common  Shares.  Before taking any action which
would cause an adjustment  effectively reducing the portion of the Warrant Price
allocable to each Share below the then  nominal  value per Share  issuable  upon
exercise of the Warrants,  the Company will take any corporate action which may,
in the  opinion of its  counsel,  be  necessary  in order that the  Company  may
validly and legally issue fully paid and  nonassessable  Shares upon exercise of
the Warrants.

         6.8.  Independent Public Accountants.  The Company may retain a firm of
independent  public  accountants of recognized  national  standing in the United
States  (which may be any such firm  regularly  employed by the Company) to make
any computation required under this Section.

         6.9. Statement on Warrant Certificates. Irrespective of any adjustments
in the  number  of  securities  issuable  upon  exercise  of  Warrants,  Warrant
certificates  theretofore or thereafter  issued may continue to express the same
number of securities as are stated in the similar Warrant certificates initially
issuable  pursuant to this Agreement.  However,  the Company may, at any time in
its reasonable  discretion,  make any change in the form of Warrant  certificate
that it may deem appropriate and that does not affect the substance thereof; and
any Warrant certificate hereafter issued,  whether upon registration of transfer
of, or in exchange or substitution for, an outstanding Warrant certificate,  may
be in the form so changed.

         6.10.  Adjustment  by Board of  Directors.  If any  event  occurs as to
which,  in the opinion of the Board of Directors of the Company,  the provisions
of this Section 6 are not strictly

                                      -17-
<PAGE>

applicable or if strictly  applicable would not fairly protect the rights of the
Warrantholder  in accordance  with the essential  intent and  principles of such
provisions,  then  the  Board  of  Directors  shall  make an  adjustment  in the
application of such  provisions,  in accordance  with such essential  intent and
principles, so as to protect such rights as aforesaid, but in no event shall any
adjustment  have the  effect  of  increasing  the  Warrant  Price  as  otherwise
determined  pursuant to any of the  provisions  of this  Section 6 except in the
case of a combination  of shares of a type  contemplated  in Section  6.1(a) and
then in no event to an amount larger than the Warrant Price as adjusted pursuant
to Section 6.1(a).

         Section 7. Fractional Interests. The Company shall not issue fractional
Common  Shares upon any  exercise of any  Warrants.  If any fraction of a Common
Share  would,  except for the  provisions  of this Section 7, be issuable on the
exercise of any  Warrants,  the Company shall pay an amount in cash equal to the
Market Price (as defined in Section 2(b) hereof, except if the Common Shares are
not publicly  traded,  as  determined in good faith by the Board of Directors of
the Company)  multiplied by such  fraction,  provided,  however,  that no amount
shall be paid by the Company of less than U.S. $5.00.

         Section 8. No Rights as Shareholder, Notices to Warrantholder.  Nothing
contained in this  Agreement or in the Warrants shall be construed as conferring
upon the  Warrantholder  any rights as a shareholder  of the Company,  including
(without  limitation) the right to vote, receive  dividends,  consent or receive
notices  as a  shareholder  in respect of any  meeting of  shareholders  for the
election of  directors  of the Company or any other  matter,  except as provided
herein.  If,  however,  at any time prior to the  expiration of the Warrants and
prior to their exercise in full,  any one or more of the following  events shall
occur:

              (a) any action  which  would  require an  adjustment  pursuant  to
         Section 6.1 or 6.3; or

              (b) the Company  shall  declare any cash  dividend upon its Common
         Shares; or

              (c) the Company  shall declare any dividend upon its Common Shares
         payable in stock or make any special dividend or other  distribution to
         the holders of its Common Shares; or

                                      -18-
<PAGE>

              (d) the Company shall offer Purchase  Rights to the holders of its
         Common Shares; or

              (e) there shall be any capital  reorganization or reclassification
         of the share  capital of the  Company,  including  any  subdivision  or
         combination of its  outstanding  Common Shares,  or amalgamation of the
         Company  with,  or sale of all or  substantially  all of its assets to,
         another corporation; or

              (f) there shall be a dissolution, liquidation or winding up of the
         Company (other than in connection  with an  amalgamation or sale of its
         property,  assets and  business as an entirety or  substantially  as an
         entirety);

then  the   Company   shall  give  notice  in  writing  of  such  event  to  the
Warrantholder,  as provided in Section 10 hereof,  at least 20 days prior to (i)
the date fixed as a record  date or the date of closing the  transfer  books for
the  determination  of  the  shareholders  entitled  to any  relevant  dividend,
distribution,  Purchase  Rights  or other  rights  or for the  determination  of
shareholders entitled to vote on such proposed reorganization, reclassification,
amalgamation,  sale,  dissolution,  liquidation  or winding up and (ii) the date
when any such reorganization, reclassification, amalgamation, sale, dissolution,
liquidation or winding up shall take place.  Such notice in accordance  with the
foregoing  clause  (i) shall  also  specify,  in the case of any such  dividend,
distribution or Purchase Rights,  the date on which the holders of Common Shares
shall be entitled  thereto,  and such notice in  accordance  with the  foregoing
clause (ii) shall also  specify  the date on which the holders of Common  Shares
shall be  entitled to  exchange  their  Common  Shares for  securities  or other
property deliverable upon such reorganization,  reclassification,  amalgamation,
sale, dissolution, liquidation or winding up, as the case may be.

         Section  9. No  Dilution  or  Impairment.  The  Company  will  not,  by
amendment of its charter or through reorganization,  amalgamation,  dissolution,
sale of  assets  or any  other  voluntary  action,  avoid or seek to  avoid  the
observance or performance  of any of the terms of this Warrant,  but will at all
times in good  faith  assist in the  carrying  out of all such  terms and in the
taking of all such action as may be necessary or appropriate in order to protect
the rights of the Warrantholder  against dilution or other  impairment.  Without
limiting the generality of the foregoing,  the Company will not increase the par
value of any shares  receivable  upon the  exercise  of this  Warrant  above the
amount payable therefor upon such exercise,  and at all times will

                                      -19-
<PAGE>

take all such  action  as may be  necessary  or  appropriate  in order  that the
Company may validly and legally issue fully paid and non-assessable  shares upon
the exercise of this Warrant.

         Section 10. Notices. Any notice hereunder shall be in writing and shall
be effective  when  delivered in person or by facsimile  transmission,  or seven
business  days after being  mailed by  certified  or  registered  mail,  postage
prepaid,  return receipt  requested,  to the appropriate  party at the following

                               OF YUKON TERRITORY)

                       WARRANTS TO PURCHASE COMMON SHARES


         This certifies that, for value received, Warburg, Pincus Ventures, L.P.
(the  "Warrantholder")  is the  registered  owner  of  2,000,000  warrants  (the
"Warrants") each to purchase from Sonus Corp. (the "Company"), at any time prior
to 5:00 p.m., Pacific Time, on October 1, 2004, one common share of the Company,
without par value (a "Common  Share") at a purchase  price per Common Share (the
"Warrant Price"),  equal to U.S. $6.75,  provided that if the Series A Amendment
Filing Date has not occurred on or prior to March 31, 2000,  then from and after
March 31,  2000,  the Warrant  Price shall equal U.S.  $4.00.  The  Warrants are
subject
                                      -1-
<PAGE>

to, and the Warrantholder,  by acceptance of this certificate,  consents to, all
the terms and provisions of, the Amended and Restated Warrant Agreement dated as
of October 1, 1999,  between the  Warrantholder  and the Company  (the  "Warrant
Agreement"). Any capitalized terms used herein and not defined herein shall have
the meanings assigned to such terms in the Warrant Agreement.

         The Warrants  evidenced  hereby may be exercised in whole or in part by
presentation  of this Warrant  Certificate  with the  Purchase  Form herein duly
executed  (with a signature  guarantee as provided  therein),  and  simultaneous
payment of the Warrant Price for each Warrant exercised, at the principal office
of the  Company.  Payment  of such  price  shall  be made at the  option  of the
Warrantholder  in cash by certified or official bank check or by wire  transfer.
Subject  to the  terms and  conditions  set  forth in  Section 2 of the  Warrant
Agreement,  the  Warrantholder  may also receive  Common Shares without any cash
payment by presentation of this Warrant  Certificate with the Cashless  Exercise
Form herein duly executed  (with a signature  guarantee as provided  therein) at
the principal office of the Company.

         Upon any partial exercise of the Warrants evidenced hereby, there shall
be signed and issued to the  Warrantholder a new Warrant  Certificate in respect
of the Common  Shares as to which the Warrants  evidenced  hereby shall not have
been exercised.  These Warrants may be exchanged at the office of the Company by
surrender  of this  Warrant  Certificate  properly  endorsed for one or more new
Warrants of the same aggregate  number of Common Shares as here evidenced by the
Warrant or Warrants  exchanged.  No fractional Common Shares will be issued upon
the exercise of rights to purchase hereunder, but the Company shall pay the cash
value  of any  fraction  otherwise  issuable  upon the  exercise  of one or more
Warrants, as provided in the Warrant Agreement.

         The Warrants  evidenced hereby are transferable only in accordance with
the terms and conditions set forth in Section 1.2 of the Warrant Agreement.

         This Warrant  Certificate does not entitle the  Warrantholder to any of
the rights of a shareholder of the Company.

                       as amended through October 31, 1999
                                                                October 31, 1996

         1. HealthCare  Capital Corp., a corporation duly organized and existing
under the laws of the Province of Alberta, Canada ("HealthCare"), and HealthCare
Hearing Clinics,  Inc., a corporation duly organized and existing under the laws
of the State of  Washington  ("HHC"),  for value  received  hereby  jointly  and

August      1,      1999,      at     the      office      of      Holder     at
- -----------------------------------------,  or at such other place as Holder may
designate in writing,  in such coin or currency of the United  States of America
as at the time of payment is legal  tender for the payment of public and private
debts.  HealthCare and HHC are sometimes  collectively referred to herein as the
"Companies".

         2. Deleted.

         3. The  Companies,  for  themselves  and their  successors and assigns,
covenant and agree, and by its 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 HealthCare  or HHC  (including
guarantees by HealthCare or HHC of  indebtedness  for borrowed money of others),
whether outstanding on the date hereof or hereafter created, incurred,  assumed,
or guaranteed.

         4.  Upon any  distribution  of  assets  by  HealthCare  or HHC upon any
dissolution, winding up, liquidation, or reorganization of HealthCare or HHC, as
the  case  may  be,  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 HealthCare or HHC or any
other winding up of the Companies  (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 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 the Companies of any
                  kind or character,  whether in cash, property,  or securities,
                  to which Holder would be entitled except for the provisions of
                  this  Section 4 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 the  Companies  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 4.

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 HealthCare or 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 the Companies,  their respective creditors, other
than the holders of Senior  Indebtedness,  and Holder, be deemed to be a payment
by the  Companies  to or on  account  of this note.  It is  understood  that the
provisions  of  Sections  3 and 4 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 the  Companies  and their  properties.
Nothing  contained  in Sections 3 and 4 or elsewhere in this note is intended to
or shall  impair,  as between the Companies  and Holder,  the  obligation of the
Companies,  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 the
Companies  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

                                      -2-
<PAGE>

Sections  3 and 4 of the  holders  of Senior  Indebtedness  in  respect to cash,
property,  or securities of the Companies received upon the exercise of any such
remedy.

         5. 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 the  Companies;  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
the Companies requesting permission to make a payment of principal on this note,
fail to notify the Companies in writing within 30 days after the date the notice
requesting such permission is received that such permission is denied.

         6. Nothing contained in Sections 3, 4, or 5 shall prevent the Companies
at any time except  during the  pendency of any of the  conditions  described in
Sections 4 and 5, from making the scheduled  principal  payment  provided for in
Section 1.

         7.  Holder is  entitled,  at its  option,  at any time  prior to 5 p.m.
Eastern Time on August 1, 1999, to convert the principal amount of this note (or
any portion hereof which is $1,000 or an integral  multiple thereof) into shares
of Common Stock of  HealthCare,  as said shares shall be constituted at the date
of conversion,  at the conversion  price of $1.30 principal  amount of this note
for each such share of Common Stock  (calculated  as to each  conversion  to the
nearest  one-thousandth  of a  share),  upon  the  surrender  of  this  note  to
HealthCare  at the  office  of  HealthCare,  accompanied  by  written  notice of
election to convert,  in the form attached hereto as Exhibit A, duly executed by
Holder or by its duly authorized attorney.  Share certificates will be delivered
to Holder within five  business  days. No adjustment is to be made on conversion
for  dividends  on Common Stock issued on  conversion.  HealthCare  shall not be
required to issue fractional shares upon any such conversion,  but shall make an
adjustment therefor in cash equal to the current market value of such fractional
interest  computed to the nearest  thousandth  of a share either on the basis of
the last reported  sale price of the Common Stock on the Alberta Stock  Exchange
(or, if not listed on the Alberta Stock Exchange, then on such other exchange on
which the  Common  Stock is  listed as  HealthCare  may  designate)  on the last
business day prior to the date of  conversion  or if there shall not have been a
sale on such last business  day, on the average of the bid and asked  quotations
therefor on such  exchange on such last  business  day,  or, if the Common Stock
shall not then be listed on any exchange,  such adjustment shall be made using a
value of $1.30 per share.

      8. The conversion price shall be adjusted from time to time as follows:

             (a)  In case  HealthCare  shall,  at any time or from  time to time
                  while this note is  outstanding,  (i) pay a dividend in shares
                  of its Common Stock, (ii) subdivide its outstanding  shares of
                  Common Stock,  (iii) combine its outstanding  shares of Common
                  Stock  into a  smaller  number  of  shares,  or (iv)  issue by
                  reclassification of

                                      -3-
<PAGE>

                  its shares of Common Stock any shares of stock of  HealthCare,
                  the conversion price in effect immediately prior thereto shall
                  be  adjusted  so  that  upon   surrender   of  this  note  for
                  conversion,  Holder shall be entitled to receive the number of
                  shares of Common Stock or other  securities of HealthCare that
                  it would have owned or have been entitled to receive after the
                  happening of any of the events  described  above had this note
                  been  converted  immediately  prior to the  happening  of such
                  event. Any adjustment made pursuant to this Section 8(a) shall
                  become effective in the case of a dividend on the payment date
                  retroactively to immediately  after the opening of business on
                  the date  following the record date for the  determination  of
                  shareholders entitled to receive such dividend, subject to the
                  provisions of Section 8(c), and shall become  effective in the
                  case  of  a  subdivision,   combination  or   reclassification
                  immediately after the opening of business on the day following
                  the   day   when    such    subdivision,    combination,    or
                  reclassification, as the case may be, becomes effective.

             (b)  Except as herein  otherwise  provided,  no  adjustment  in the
                  conversion  price shall be made by reason of the issuance,  in
                  exchange for cash,  property or services,  of shares of Common
                  Stock, or any securities  convertible into or exchangeable for
                  shares of Common Stock,  or carrying the right to purchase any
                  of the foregoing.

             (c)  If HealthCare shall take a record of the holders of its Common
                  Stock  for  the  purpose  of  entitling  them to  receive  any
                  dividend,  for any  subscription  or  purchase  rights  or any
                  distribution and shall, thereafter and before the distribution
                  to stockholders of any such dividend, subscription or purchase
                  rights or  distribution,  legally  abandon  its plan to pay or
                  deliver  such  dividend,  subscription  or purchase  rights or
                  distribution, then no adjustment of the conversion price shall
                  be required by reason of the taking of such record.

             (d)  No adjustment in the conversion price shall be required unless
                  such  adjustment  would  require an increase or decrease of at
                  least 1 percent in such  price;  provided,  however,  that any
                  adjustment  which  by  reason  of  this  Section  8(d)  is not
                  required  to be made shall be carried  forward  and taken into
                  account in any subsequent  adjustment.  All calculations under
                  this  Section  8 shall be made to the  nearest  cent or to the
                  nearest one thousandth of a share, as the case may be.

         9. In case of any  reclassification  or change of outstanding shares of
Common Stock  issuable upon  conversion of this note (other than a change in par
value,  or from par value to no par value, or from no par value to par value, or
as a result of a subdivision or combination), or in case of any consolidation of
HealthCare which one or more other  corporations  (other than a consolidation in
which HealthCare is the continuing  corporation and which does not result in any
reclassification  or change of outstanding  shares of Common Stock issuable upon
conversion of this note),  or in case of the merger of  HealthCare  into another
corporation,  or in case of any sale or conveyance to another corporation of the
property  of  HealthCare  as  an  entirety  or  substantially  as  an  entirety,
HealthCare,  or such  successor or purchasing  corporation,  as the case may be,
Holder  shall  thereafter  have the right to convert this note into the kind and
amount of shares of stock and other securities and property  (including cash) or
any  combination   thereof  receivable  upon  such   reclassification,   change,
consolidation,  merger,  sale, or conveyance by a holder of the

                                      -4-
<PAGE>

number of shares of Common Stock into which this note might have been  converted
immediately prior to such reclassification, change, consolidation, merger, sale,
or conveyance, subject to adjustments which shall be as nearly equivalent as may
be  practicable  to the  adjustments  provided  for in  Section  8 and any  such
adjustments  which  shall  be  approved  by the  Board  of  Directors  shall  be
conclusive  for all purposes of this Section 9. The provisions of this Section 9
shall similarly apply to successive reclassification,  changes,  consolidations,
mergers, sales, and conveyances.

         10. 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 the Companies or of any successor corporations,  whether by virtue of
any  constitution,  statute,  or  rule  of  law,  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.

         11. The  occurrence  of any one or more of the  following  events shall
constitute an Event of Default under this note:

             (a)  HealthCare  or HHC  shall  fail  to  observe  or  perform  any
      obligation to be observed or performed by them under this note,  under the

      Companies and Holder,  or under the Security  Agreement 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

      performance of the obligation is not possible within thirty (30) days;

             (b) Either  HealthCare  or 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) Either  HealthCare  or HHC shall admit its inability to pay its
      debts as they mature or shall make an assignment for the benefit of any of
      its creditors;

             (d) Proceedings in bankruptcy,  or for reorganization of HealthCare
      or HHC, or for the  readjustment  of any of  HealthCare's  or HHC's debts,

                            NONCOMPETITION AGREEMENT


         AGREEMENT dated January 25, 1999, between SONUS-USA, INC., a Washington
corporation ("SONUS") and GREGORY J. FRAZER ("Employee").

                                    RECITALS

                  A. SONUS entered into stock purchase  agreements with Employee
for the following companies on various dates:

                     Hearing Care Associates-Northridge, Inc.;
                     Hearing Care Associates-Glendale, Inc.;
                     Hearing Care Associates-Glendora, Inc.;
                     Hearing Care Associates-Los Angeles, Inc.;
                     Hearing Care Associates-Arcadia, Inc.;
                     Hearing Care Associates-Sherman Oaks, Inc.;
                     Audio-Vestibular Center, Inc.;
                     Hearing Care Associates-Lancaster, Inc.;
                     Hearing Care Associates-Santa Monica, Inc.;
                     Hearing Care Associates-Inglewood, Inc.; and
                     Hearing Care Associates-Montclair, Inc.

(collectively, "HCA Companies");

                  B. In connection with the purchase of HCA Companies,  Employee
and SONUS entered into certain  noncompetition  agreements  prohibiting employee
from competing with SONUS in certain geographic areas.

                  C. Employee was a principal shareholder, a member of the board
of  directors,  and a  key  executive  officer  of  HCA  Companies.  Because  of
Employee's  detailed  knowledge of HCA Companies and  Employee's  reputation and
relationship with patients, customers, suppliers,  distributors,  employees, and
other parties doing business with HCA Companies.  SONUS  recognizes the Employee
acknowledges  the  detrimental  effect on and the  decrease  in value of the HCA
Companies  that would  result if Employee  were to enter into  competition  with
SONUS.

                  D. SONUS and Employee have  determined  that it is in the best
interest of each of them to expand the  geographic  area  covered by  Employee's
covenant  not to  compete.  Employee  and SONUS  acknowledge  that the  expanded
covenant not to compete is in connection with the sale of the HCA Companies.

                                      TERMS

                  In  consideration  of  the  covenants  and  agreements  of the
parties herein contained, the parties agree as follows:

                  1. Covenant Not to Compete.  For a period of three years after
the date Employee's  employment with SONUS  terminates for any reason,  Employee
will not  directly  or  indirectly  engage  in any  Competitive  Activities  (as
hereinafter  defined)  within the Territory (as hereinafter  defined).  The term
"Competitive Activities" as used herein shall mean:

                  (i)  directly or  indirectly  engaging  in,  continuing  in or
         carrying  on any  business  substantially  similar  to that  heretofore
         conducted  by SONUS,  including  owning or  controlling  any  financial
         interest  in any  corporation,  partnership,  firm  or  other  form  of
         business  organization  which  competes  with SONUS or is engaged in or
         carries on any aspect of such  business or any  business  substantially
         similar thereto;

                  (ii)  consulting  with,  advising or assisting in any way with
         respect to the  operation  of any  hearing  care  business  of the type
         conducted  by  SONUS or any  business  substantially  similar  thereto,
         whether or not for consideration, or any corporation, partnership, firm
         or other  business  organization  which is now,  becomes or is actively
         planning to become a competitor of SONUS including, but not limited to,
         advertising or otherwise endorsing the products of any such competitor;
         soliciting  customers or otherwise  serving as an intermediary  for any
         such competitor; loaning money or rendering any other form of financial
         assistance to or engaging in any form of business  transaction on other
         than an arm's length basis with any such competitor; or

                  (iii)  enticing away or otherwise  persuading  any employee of
         SONUS to alter,  modify or terminate his or her relationship with SONUS
         as an employee

provided  that this  covenant  shall not preclude  the  ownership by Employee of
securities of corporations which are listed on a national securities exchange or
traded in the national  over-the-counter market in amounts which do not exceed 5
percent of the outstanding shares of any such corporation.

         The parties  agree that the  geographic  scope of this  covenant not to
compete (the "Territory") shall cover the states of Arizona,  New Mexico and the
area of  California  which lies  north of Santa  Barbara  (except  for a 20 mile
radius  from  Saratoga,  California  and a 10 mile  radius  from San  Francisco,
California).  In the event a court of competent jurisdiction determines that the
provisions of this covenant not to compete are excessively broad as to duration,
geographical scope or activity, it is expressly agreed that this covenant not to
compete  shall  be  construed  so that the  remaining  provisions  shall  not be
affected,  but shall  remain in full force and  effect,  and any such  overbroad
provisions  shall  not be  deemed,  without  further  action  on the part of any
person, to be modified, amended and/or limited, but only to the extent necessary
to render the same valid and enforceable in such jurisdiction.

                  2. Covenant of Confidentiality. Employee shall not at any time
subsequent to the date hereof,  except as explicitly requested by SONUS, (i) use
for any purpose,  (ii)  disclose to any person,  or (iii) keep or make copies of
documents,  tapes,  discs or program  containing,  any confidential  information
concerning  the  operations  of  SONUS.  For  purposes   hereof,   "confidential
information" shall mean and include, without limitation,  trade rights, customer
lists  and  information,   and  all  other  information  concerning  operations,
equipment, products, marketing and distribution methods not previously disclosed
to the public directly by SONUS or otherwise in the public domain.

                  3. Consideration. In consideration of Employee's covenants set
forth  herein,  SONUS  will pay to  Employee  (so long as he is not in  material
breach of the terms hereof) the sum of $6,303 per month on the first day of each
month during the period beginning with January 1, 1999 and ending with September
1, 2001.  Under no  circumstances  shall SONUS be relieved of its  obligation to
make the  foregoing  payments  pursuant  to this  Agreement  as a result  of the
termination  of  Employee's  employment  with SONUS,  regardless of whether such
termination  is by SONUS or  Employee  and  regardless  of whether it is with or
without good cause.

                  4. Equitable  Relief of Violations.  Employee  agrees that the
provisions and restrictions contained in this Agreement are necessary to protect
the legitimate continuing interests of SONUS and that any violation or breach of
these  provisions will result in irreparable  injury to SONUS for which a remedy
at law would be inadequate  and that, in addition to any relief at law which may
be available to SONUS for such  violation or breach and  regardless of any other
provision contained in this Agreement, SONUS shall be entitled to injunctive and
other equitable relief as a court may grant after considering the intent of this
Agreement.

                  If  Employee  violates  the  terms  of  this  Agreement,  such
violation  shall  constitute  a breach  of all other  noncompetition  agreements
entered  into in  connection  with the  purchase  of HCA  Companies  (the "Prior
Agreements"),  and if Employee violates the terms of the Prior Agreements,  such
violation shall constitute a breach of this Agreement.

                  If SONUS violates the terms of this Agreement,  such violation
shall  constitute a breach of the Prior  Agreements,  and if SONUS  violates the
terms of the Prior Agreements,  such violation shall constitute a breach of this
Agreement.

                  5. Assignment.  Neither this Agreement nor any interest herein
may be assigned by Employee.  SONUS may freely assign this Agreement and any and
all interests herein to any "affiliate" (as such term is currently defined under
the  Securities  Act of 1934, as amended),  or in connection  with the transfer,
directly  or  indirectly,  of all  or  substantially  all,  of  the  assets  and
businesses acquired from Employee.

<PAGE>

                  6. GENERAL.

                  6.1.  Governing  Law. This  Agreement  shall be subject to and
governed  by the laws of the State of  California,  excluding  any choice of law
rules that may direct the application of the laws of another jurisdiction.

                  6.2. Binding Effect.  This Agreement shall be binding upon and
inure to the benefit of Employee  and SONUS and their  respective  heirs,  legal
representatives, executors, administrators, successors, and permitted assigns.

                  6.3. Integration; Amendment; Waiver. This Agreement sets forth
all of the  understandings of the parties with respect to its subject matter and
supersedes  any and all other  agreements,  either  oral or in  writing,  of the
parties with respect to the subject  hereof.  No change or  modification of this
Agreement shall be valid unless in writing and signed by the party against which
it is to be  enforced.  No waiver of any  provision of this  Agreement  shall be
valid unless written and signed by the person or party to be charged.

                  6.4. 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.

                  6.5. Headings. The headings of this Agreement are inserted for
convenience  only  and  are  not to be  considered  in the  construction  of the
provisions hereof.

                  6.6. Attorney Fees. In the event a suit or action is commenced
for the  interpretation  or enforcement of this Agreement,  the prevailing party
shall be  entitled  to collect  from the losing  party in addition to all of the
costs and expenses, reasonable attorney fees at trial and on appeal.

                               AMENDMENT AGREEMENT

                  AGREEMENT  effective  as of  August  1,  1998  by and  between
SONUS-USA,  INC.  (formerly  known  as  HealthCare  Hearing  Clinics,  Inc.),  a
corporation  duly  organized  and  existing  under  the  laws  of the  State  of
Washington ("Sonus"), and GREGORY J. FRAZER ("Employee").

                                   WITNESSETH:

                  WHEREAS,  Sonus and Employee executed an Employment  Agreement
dated as of October 1, 1996 (the "Employment Agreement");

                  WHEREAS,  the parties  desire to enter into this  Amendment to
amend certain terms of the Employment Agreement;

                  NOW,  THEREFORE,  the parties hereto,  intending to be legally
bound, and for valuable consideration,  the receipt and sufficiency of which are
hereby acknowledged, agree as follows:

                  1. Salary Reduction.  Section 3.1 of the Employment  Agreement
is hereby  amended to provide that  Employee's  base salary shall be $80,000 per
year.

                  2.  Prior  Year  Bonuses.   Employee  forever  discharges  and
releases  Sonus from any and all bonuses due to Employee for Sonus' fiscal years
ended 1997 and 1998 pursuant to Section 3.2 of the Employment Agreement.

                  3. Car Allowances.  Employee discharges and releases Sonus for
the  remainder  of the  term  of the  Employment  Agreement  from  any  and  all
automotive  reimbursements  due to Employee  pursuant  to Section  3.3(e) of the
Employment Agreement.

                  4.  Overpayment.  From August 1, 1998 to January 15, 1999, the
reductions  contemplated  by  this  Agreement  in  Sections  1  and 3  were  not
implemented.  Employee agrees to reimburse Sonus for such overpayment.  Employee
was overpaid a total of $20,300, which is being paid to Sonus as follows:

                  Employee  has  delivered to Sonus its  promissory  note in the
                  principal amount of $20,300,  payable in full on June 30, 1999
                  without  interest.  The promissory  note may be satisfied,  at
                  Employee's  option,  by  offsetting  the amount due under such
                  note  against  payments  scheduled  to be  made  by  Sonus  to
                  Employee in the future.

                  As a result of the  overpayment,  Sonus has issued Employee an
                  incorrect Form W-2. As soon as practicable,  Sonus shall issue
                  Employee  a  corrected  Form W-2.  In  addition,  Sonus  shall
                  reimburse  Employee for any and all amounts withheld  pursuant
                  to the  Federal  Insurance  Contributions  Act (the  "Act") in
                  excess of the amounts  properly  withheld under such Act based
                  on the  amount of wages paid as stated on the  corrected  Form
                  W-2.

                  5. Required  Acquisitions.  Employee  forever  discharges  and
releases Sonus from any and all requirements to purchase  Employee's interest in
Hearing  Care   Associates-Encino   and   Employee's   shares  of  Hearing  Care
Associates-North  Hollywood,  Inc. as was originally set forth in a letter dated
September 26, 1996 by Brandon M. Dawson to Employee, et al.

                  6.  Access to  In-House  Resources.  Sonus  agrees to  provide
Employee  with access to Sonus'  in-house  resources,  at no charge,  to discuss
legal  issues  regarding  Hearing  Care   Associates-Encino   and  Hearing  Care
Associates-North Hollywood, Inc. Employee acknowledges that Sonus, its employees
and agents do not represent  Employee in any legal matters and that Employee has
been advised to seek his own counsel before proceeding with any transaction.

                  7.  Indemnification.   Sonus  agrees  to  indemnify  and  hold
Employee  harmless  from and against all claims and  liabilities  arising out of
actions by Employee as an employee or director of Sonus (in  addition to actions
taken by Sonus) from and after October 1, 1996. Employee agrees to indemnify and
hold Sonus harmless from and against all claims and  liabilities  arising out of
actions by Employee prior to October 1, 1996.

                  8. Full  Force and  Effect.  Except  as  specifically  amended
herein,  the  Employment  Agreement  shall  remain in full  force and  effect in
accordance with its terms.

                  9. Entire  Agreement.  This  Agreement  represents  the entire
agreement between the parties hereto. There are no other agreements,  written or
oral between these parties relating to the subject matter hereof.

                  10.   Counterparts.   This   Agreement   may  be  executed  in
counterparts, each of which shall constitute an original, and all of which taken
together shall constitute one and the same Agreement.

                                      -2-

                          DESCRIPTION OF CAPITAL STOCK
                                 OF SONUS CORP.

                  The authorized  capital stock of Sonus Corp.  (the  "Company")
consists of an unlimited  number of Common Shares,  without nominal or par value
(the "Common  Shares"),  and an unlimited  number of Preferred  Shares,  without
nominal or par value (the  "Preferred  Shares").  The Company  was  incorporated
under the laws of the province of Alberta, Canada in July 1993 and was continued
under the laws of the Yukon Territory, Canada in 1998.

                  The  Company's  Board  of  Directors  (the  "Board")  has  the
authority to issue Preferred  Shares 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  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
holders of Common Shares.  The outstanding  series of Preferred Shares include a
series  designated  as Series A  Convertible  Preferred  Shares  (the  "Series A
Shares"),  consisting  of 13,333,333  shares issued on December 24, 1997,  and a
series  designated  as Series B  Convertible  Preferred  Shares  (the  "Series B
Shares"), consisting of 2,500,000 shares issued on October 1, 1999. A summary of
certain of the  preferences,  limitations  and  relative  rights of the Series A
Shares and Series B Shares is set forth below.

COMMON SHARES

                  Voting  Rights.  Holders of Common  Shares are entitled to one
vote per  share at all  meetings  of  shareholders  of the  Company.  Except  as
otherwise required by law or unless the Board determines  otherwise with respect
to a particular series of Preferred Shares,  the Common Shares and all series of
the Preferred Shares having voting rights will vote together as one class. Under
the Business  Corporations Act (Yukon),  the holders of each class of shares are
generally  entitled  to vote as a  separate  class  (whether  or not such  class
otherwise has voting  rights) upon any proposal to amend the Company's  Articles
to (i)  increase or decrease  the maximum  number of  authorized  shares of that
class,  (ii) increase the maximum  number of authorized  shares of another class
having  rights or  privileges  equal or superior  to those of that class,  (iii)
effect an exchange,  reclassification or cancellation of all or a portion of the
shares of that  class,  (iv)  add,  change or  remove  the  rights,  privileges,
restrictions  or conditions  attached to that class,  (v) increase the rights or
privileges of any class having  rights or privileges  equal or superior to those
of that class,  (vi) create a new class  having  rights or  privileges  equal or
superior to those of that class,  (vii) change the rights or  privileges  of any
class with inferior rights or privileges such that they are equal to or superior
to those of that class;  (viii)  effect an  exchange of shares of another  class
into the shares of that  class,  or (ix)  restrict  the issue or transfer of the
shares of that class or extend or remove that restriction.

                  Other. All Common Shares rank ratably with regard to dividends
(if and when declared by the Board). In the event of a liquidation, dissolution,
or winding up of the  Company,  holders of Common  Shares 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

                                      -1-
<PAGE>

preference of any outstanding  class or series of Preferred  Shares.  The Common
Shares do not have preemptive  rights.  All outstanding  Common Shares are fully
paid and nonassessable.

SERIES A CONVERTIBLE PREFERRED SHARES

                  Certain of the preferences, limitations and relative rights of
the Series A Shares are summarized below.

                  Voting Rights. Each Series A Share is entitled to one-fifth of
a vote (or such other number of votes equal to the number of Common  Shares into
which  such  Series  A Share  shall  be  convertible  from  time to time) in the
election  of  directors  and in any other  matters  presented  for action by the
Company's  shareholders.  Except to the extent otherwise  required by law or the
Company's  Articles,  holders  of Series A Shares  and of any other  outstanding
series of Preferred  Shares will vote together with the holders of Common Shares
as a single class. See "Common Shares--Voting  Rights." Any change in the rights
and  preferences of the Series A Shares will require the approval of the holders
of at least 66-2/3% of the outstanding  Series A Shares,  voting separately as a
class.

                  Dividends.  Each Series A Share is entitled to receive,  when,
as and if declared by the Board out of the Company's  assets  legally  available
for payment,  cumulative  dividends from the date of original issuance,  payable
annually  at a rate of 5% per annum on a base  amount  of $1.35  per share  (the
"Base  Amount").  All accrued and unpaid  dividends  will be forfeited  upon the
conversion of the Series A Shares. The dividend rate will be subject to increase
on  specified  dates in the  event  that  certain  conditions  (the  "Triggering
Conditions") have not been met. The Triggering Conditions are as follows:

                  (a)  The  Common  Shares  are  listed  on the New  York  Stock
         Exchange,  the American Stock  Exchange,  or the Nasdaq National Market
         (each a "U.S. Principal Market");

                  (b) The Common Shares are traded on a U.S. Principal Market at
         a daily  closing  price greater than $12.00 per Common Share on each of
         the ten consecutive trading days preceding the applicable date; and

                  (c) The Company's net income before income taxes, dividends on
         the Series A Shares and Series B Shares,  and  amortization of goodwill
         and covenants not to compete for the three consecutive  fiscal quarters
         preceding  the  applicable  date shall have averaged at least $0.35 per
         fully diluted  Common Share per fiscal  quarter (for purposes of making
         this  calculation,  the Common Shares issuable upon the exercise of the
         Warburg  Warrants (as defined below under the heading  "Warrants") will
         not be counted).

         If the Triggering Conditions have not been met by:

                  (x) January 1, 2003, the dividend rate will  thereafter be 15%
         per annum of the Base Amount;

                  (y) January 1, 2004, the dividend rate will  thereafter be 18%
         per annum of the Base Amount; or

                                      -2-
<PAGE>

                  (z) January 1, 2005, the dividend rate will  thereafter be 21%
         per annum of the Base Amount.

                  As soon as the Triggering Conditions have been satisfied,  the
dividend rate will revert to 5% per annum of the Base Amount.  All references to
per share amounts or prices with respect to the  Triggering  Conditions  will be
adjusted for any subdivision,  consolidation,  or reclassification of the Common
Shares.

                  Dividends on the Series A Shares may, in the discretion of the
Board and subject to applicable  regulatory approvals at the time of payment, be
paid in Common  Shares  based on the market  price of such  shares.  Accruals of
dividends on Series A Shares will not bear interest.

                  No dividends on the Common Shares, the Series B Shares, or any
other share capital ranking, as to dividends, equal to or junior to the Series A
Shares as to dividends may be declared or paid unless full accumulated dividends
on the Series A Shares have been paid or declared and sufficient funds set aside
for such  payment.  The  foregoing  prohibition  will not apply to  dividends or
distributions payable in Common Shares or certain other comparable actions.

                  Liquidation  Preference.  In the  event  of any  voluntary  or
involuntary liquidation,  dissolution,  or winding up of the Company, subject to
the rights of holders of any  securities  of the Company  ranking  senior to the
Series A  Shares  upon  liquidation,  the  holders  of  Series A Shares  will be
entitled to receive, out of the assets of the Company available for distribution
to shareholders,  before any distribution of assets is made to holders of Common
Shares or any  other  securities  ranking  junior  to the  Series A Shares  upon
liquidation, a liquidating distribution in an amount equal to the greater of (i)
$1.35 per share plus any  accrued and unpaid  dividends  or (ii) the amount that
would have been distributable to such holders if they had converted their Series
A Shares into Common Shares immediately prior to such dissolution,  liquidation,
or winding  up, plus any accrued  and unpaid  dividends.  The sale,  conveyance,
mortgage,  pledge or lease of all or substantially all the assets of the Company
will  be  deemed  to be a  liquidation  of  the  Company  for  purposes  of  the
liquidation rights of the holders of Series A Shares.  After payment of the full
amount of the liquidating  distribution to which they are entitled,  the holders
of  Series A Shares  will  have no right to any of the  remaining  assets of the
Company.

                  Optional  Redemption.  The Series A Shares may not be redeemed
before December 24, 2002. Thereafter, the Series A Shares may be redeemed at the
option of the  Company,  in whole or in part.  The  redemption  price will be an
amount  equal to the  greater of (i) $1.35 per share plus any accrued and unpaid
dividends or (ii) the fair market value of a Series A Share as  determined  by a
nationally  recognized  independent  investment  banking firm selected by mutual
agreement of the Company and the holder of a majority of the outstanding  Series
A Shares.  The Series A Shares are not subject to  mandatory  redemption  or any
sinking fund provisions.

                  Conversion Rights. The Series A Shares may be converted at any
time,  in whole or in part,  at the option of the holder  thereof,  into  Common
Shares.  The  conversion  rate is currently  equal to one Common Share for every
five Series A Shares surrendered for conversion.  The conversion rate is subject
to further adjustment for stock dividends, stock splits,

                                      -3-
<PAGE>

recapitalizations,  and other anti-dilution adjustments.  Upon the conversion of
any Series A Shares,  any  accrued  and unpaid  dividends  with  respect to such
shares will be forfeited.  The Company has the right to force  conversion of the
Series A Shares,  in whole or in part,  upon  satisfaction of all the Triggering
Conditions.  Common Shares  issuable upon conversion of the Series A Shares will
be fully paid and nonassessable and will not have preemptive rights.

         Preemptive Rights.  The Series A Shares do not have preemptive rights.

SERIES B CONVERTIBLE PREFERRED SHARES

                  Certain of the preferences, limitations and relative rights of
the Series B Shares are summarized below.

                  Voting Rights. Each Series B Share is entitled to one vote (or
such other number of votes equal to the number of Common  Shares into which such
Series B Share  shall be  convertible  from  time to  time) in the  election  of
directors  and in any  other  matters  presented  for  action  by the  Company's
shareholders.  Except to the extent  otherwise  required by law or the Company's
Articles,  holders  of Series B Shares  and of any other  outstanding  series of
Preferred  Shares  will vote  together  with the  holders of Common  Shares as a
single class. See "Common  Shares--Voting  Rights." Any change in the rights and
preferences  of Series B Shares will  require the  approval of the holders of at
least 66-2/3% of the outstanding Series B Shares, voting separately as a class.

                  Dividends.  No  dividends  will be declared on Series B Shares
until  October 31,  2000.  At October 31,  2000,  if the Company  meets the 2000
Earnings  Target (as  defined  below),  each  Series B Share will be entitled to
receive,  when and as declared by the Board out of the Company's  assets legally
available  for  payment,  preferential,  cumulative  dividends in respect of the
period  beginning  October 1, 1999,  and ending  October 31, 2000, and quarterly
thereafter, payable in U.S. dollars, at a rate of 8% per annum until October 31,
2004;  12% per annum from  November 1, 2004 through  October 31,  2005;  15% per
annum from November 1, 2005 through October 31, 2006; and 18% per annum from and
after  November  1,  2006,  each on a base  amount of $4.00 per share (the "Base
Amount").

                  The 2000  Earnings  Target  will be deemed to have been met if
the Company's  "EBTA,"  defined as net income before income taxes,  dividends on
Series A Shares and Series B Shares,  and amortization of goodwill and covenants
not to compete, for the fiscal year ending July 31, 2000, is equal to or greater
than $0.20 per fully diluted  Common Share.  For purposes of  calculating  EBTA,
certain costs  incurred by the Company in connection  with the hiring of a Chief
Financial  Officer ("CFO Costs") will be added back to net income  provided such
person is hired on or before  January 31,  2000.  Common  Shares  issuable  upon
exercise of the Warburg  Warrants  will be excluded for purposes of  calculating
the number of fully diluted Common Shares.

                  If the 2000 Earnings Target is not met,  dividends will not be
payable until the Company meets the quarterly  earnings  targets set forth below
(the "Quarterly  Earnings  Targets") for four consecutive  fiscal quarters.  The
Quarterly Earnings Targets are as follows:

                  If the  Quarterly  Earnings  Targets  are  not  met  for  four
consecutive fiscal quarters by the fiscal quarter ended July 31, 2002, dividends
will not accrue or be payable on Series B Shares.

                  All accrued and unpaid  dividends  will be forfeited  upon the
conversion of Series B Shares. Accruals of dividends on Series B Shares will not
bear interest.

                  No dividends on the Common Shares, the Series A Shares, or any
other share capital  ranking,  as to  dividends,  equal to or junior to Series B
Shares as to dividends may be declared or paid unless full accumulated dividends
on Series B Shares have been paid or declared and sufficient funds set aside for
such  payment.  The  foregoing  prohibition  will  not  apply  to  dividends  or
distributions payable in Common Shares or certain other comparable actions.

                  Liquidation  Preference.  In the  event  of any  voluntary  or
involuntary dissolution,  liquidation,  or winding up of the Company, subject to
the rights of holders of any securities of the Company  ranking senior to Series
B Shares  upon  liquidation,  the holders of Series B Shares will be entitled to
receive,  out of the  assets  of  the  Company  available  for  distribution  to
shareholders,  before  any  distribution  of assets is made to holders of Common
Shares  or  any  other  securities  ranking  junior  to  Series  B  Shares  upon
liquidation, a liquidating distribution in an amount equal to the greater of (i)
$4.00 per share  (subject to adjustment  as provided in the  Articles)  plus any
accrued  and  unpaid   dividends  or  (ii)  the  amount  that  would  have  been
distributable  to such holders if they had converted  their Series B Shares into
Common Shares immediately prior to such dissolution, liquidation, or winding up,
plus any  accrued  and  unpaid  dividends,  whether or not  declared.  The sale,
conveyance,  mortgage, pledge or lease of all or substantially all the assets of
the Company  will be deemed to be a  liquidation  of the Company for purposes of
the liquidation  rights of the holders of Series B Shares.  After payment of the
full amount of the  liquidating  distribution  to which they are  entitled,  the
holders of Series B Shares will have no right to any of the remaining  assets of
the Company.

                  Optional  Redemption.  The Series B Shares may not be redeemed
before  October 1, 2004.  Thereafter,  Series B Shares  may be  redeemed  at the
option of the Company, in whole or in part, for an amount per share equal to the
applicable  Conversion Rate then in effect  multiplied by the greater of (1) the
conversion price then in effect plus any accrued and unpaid dividends per Series
B Share or (2) the fair  market  value  of a Series B Share as  determined  by a
nationally  recognized  independent  investment  banking firm selected by mutual
agreement  of the Company  and the  holder(s)  of a majority of the  outstanding
Series B Shares.  Series B Shares are not subject to mandatory redemption or any
sinking fund provisions.

                  Conversion  Rights.  Series B Shares may be  converted  at any
time,  in whole or in part,  at the option of the holder  thereof,  into  Common
Shares.  The number of Common Shares  issuable upon  conversion of each Series B
Share (the  "Conversion  Rate") will be equal to an amount  determined by adding
$10,000,000  (the  original  purchase  price),  plus an  adjustment  factor  (as
described  below) (the  "Adjustment  Factor"),  and dividing  that result by the
conversion  price,  and then again by  2,500,000  (the number of Series B Shares
originally sold) (the "Conversion Rate Formula").  The initial Adjustment Factor
is zero and the  initial  conversion  price is $4.00,  resulting  in an  initial
Conversion  Rate  of one  Common  Share  per  Series  B  Share  surrendered  for
conversion.

                  The  Conversion  Rate is subject to increase in the event that
the Company fails to achieve the 2000 Earnings Target and, if such target is not
achieved,  to further increase until the Quarterly  Earnings Targets are met for
four  consecutive   quarters  (each  is  referred  to  herein  as  an  "Earnings
Adjustment"),  as described below. In addition,  the conversion price is subject
to decrease to the extent that the  Company's  receivables  as of July 31, 1999,
that are collected by July 31, 2000,  total less than  $4,736,000  ("Receivables
Adjustment").

                  The  Receivables  Adjustment,  if any,  will be  calculated as
follows.  In the  event  the  Company  fails  to  collect  the  full  amount  of
receivables as of July 31, 1999,  the conversion  price for Series B Shares will
be reduced by an adjustment amount determined by multiplying the amount by which
$4,736,000 exceeds actual amounts collected by the Company on or before July 31,
2000,  by a factor of 7, and  dividing  that  result by the sum of (i) the total
number of issued and  outstanding  Common Shares as of September 30, 1999,  plus
(ii) the total number of Common  Shares into which  outstanding  Series B Shares
are  convertible,  plus (iii) the total  number of Common  Shares into which the
outstanding convertible notes of the Company are convertible as of September 30,
1999, plus (iv) the total number of Shares into which the  outstanding  Series B
Shares  are  convertible  as of  October  31,  2000.  The new  conversion  price
following  a  Receivables  Adjustment  will be  calculated  by  subtracting  the
adjustment   amount  calculated  in  accordance  with  the  foregoing  from  the
conversion price then in effect.

                  An  Earnings  Adjustment  will occur if the  Company  fails to
achieve the 2000 Earnings Target.  This initial Earnings  Adjustment would cause
the  Conversion  Rate  to  increase   beginning  October  31,  2000,  such  that
approximately 200,000 additional Common Shares would be issuable upon conversion
at that date with  respect to the four fiscal  quarters  then ended.  Additional
Earnings  Adjustments  will be made each  quarter  thereafter  until the Company
meets the Quarterly Earnings Targets for four consecutive quarters.

                                      -6-
<PAGE>

                  The amount of the Adjustment Factor to be applied to determine
the new Conversion  Rate resulting from failure to reach the Quarterly  Earnings
Targets  will be  determined,  initially,  by taking 2 percent of the sum of the
original  purchase  price  ($10,000,000)  plus  the  sum of all  prior  Earnings
Adjustments  (including  an adjustment  resulting  from a failure to achieve the
2000 Earnings  Target).  After  November 1, 2004, the percentage for purposes of
calculating  the  adjustment  amount will  increase  to 3 percent  for  Earnings
Adjustments  occurring on or before October 31, 2005; 3 3/4 percent for Earnings
Adjustments occurring on or after November 1, 2005, and on or before October 31,
2006;  and 4 1/2  percent  for any  Earnings  Adjustment  occurring  on or after
November 1, 2006. The resulting Adjustment Factor will then be inserted into the
Conversion  Rate Formula to determine the new Conversion  Rate. Once the Company
has met the specified  Quarterly  Earnings Targets for four  consecutive  fiscal
quarters,  no further Earnings  Adjustments in the Conversion Rate will be made.
In the  event  the  Company  meets  the  Quarterly  Earnings  Targets  for  four
consecutive  fiscal  quarters,  Adjustments  will cease as of any fiscal quarter
ending on or after the last day of the quarter as to which such targets are met.

                  The Conversion Rate is subject to further adjustment for stock
dividends, stock splits, recapitalizations, and other anti-dilution adjustments.
Upon the  conversion  of any Series B Shares,  any accrued and unpaid  dividends
with respect to such shares will be forfeited.

                  The Company has the right to effect the  mandatory  conversion
of the Series B Shares, in whole or in part, if all of the following  conditions
have been satisfied:

                  (a)  The  Common  Shares  are  traded  on the New  York  Stock
         Exchange, the American Stock Exchange, or the Nasdaq National Market at
         a daily  closing  price  greater than $8.00 per Common Share on each of
         the ten consecutive trading days preceding the applicable date; and

                  (b) The  Company's  EBTA for the three  preceding  consecutive
         fiscal  quarters  shall have  averaged at least $.35 per fully  diluted
         Common  Share per  fiscal  quarter.  Common  Shares  issuable  upon the
         exercise of the Warburg  Warrants  are  excluded  for  purposes of this
         calculation.

                  All  references to per share amounts or prices with respect to
the above  conditions will be adjusted for any  subdivision,  consolidation,  or
reclassification of the Common Shares.

                  Common Shares  issuable upon conversion of the Series B Shares
will be fully paid and nonassessable and will not have preemptive rights.

         Preemptive Rights.  The Series B Shares do not have preemptive rights.

WARRANTS

         At October 29, 1999,  the Company had  outstanding  2,000,000  purchase
warrants  to  purchase  Common  Shares  issued in  connection  with the  private
placement of the Series A Shares in December 1997 (the "Warburg Warrants"). Each
share purchase  warrant is exercisable for one Common Share at an exercise price
of $6.75 per share until October 1, 2004.  The Company may force the exercise of
the warrants upon satisfaction of all the Triggering Conditions.

CONVERTIBLE SECURITIES AND STOCK OPTIONS

                  At October 29, 1999, the Company had  outstanding  convertible
subordinated notes in an aggregate principal amount of $930,839 convertible into
143,206 Common Shares,  13,333,333  Series A Shares  convertible  into 2,666,666
Common Shares,  2,500,000  Series B Shares  convertible  into  2,500,000  Common
Shares,  and stock  options held by  employees,  directors  and officers of, and
consultants to, the Company exercisable for a total of 2,369,000 Common Shares.

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

                  Following  is a  summary  of the  principal  Canadian  federal
income tax considerations  under the Income Tax Act (Canada) (the "Tax Act") and
the  regulations  thereunder  generally  applicable to a holder of Common Shares
who,  for  purposes of the Tax Act,  holds such shares as capital  property  and
deals at arm's  length  with  the  Company.  Generally,  Common  Shares  will be
considered to be capital  property to a holder provided the holder does not hold
the Common  Shares in the course of carrying on a business of trading or dealing
in securities and has not acquired them in one or more  transactions  considered
to be an adventure in the nature of trade.  Special rules apply to  non-resident
insurers that carry on an insurance business in Canada and elsewhere.

                  This  summary is based upon the  provisions  of the Tax Act in
force as of October 29, 1999,  all specific  proposals to amend the Tax Act that
have been publicly announced prior to such date (the "Proposed Amendments"), and
the  Company's  understanding  of  the  current  published   administrative  and
assessing policies and practices of Revenue Canada, Customs, Excise and Taxation
("Revenue  Canada").  For the purposes of this summary, it has been assumed that
the Tax Act will be amended as proposed,  although no assurance  can be given in
this regard.  This summary is not exhaustive of all possible  federal income tax
consequences  and, except for the Proposed  Amendments,  does not anticipate any
changes in the law, whether by legislative, governmental or judicial decision or
action,  nor does it take into account  provincial,  territorial  or foreign tax
considerations, which may differ significantly from those discussed herein. This
summary is not applicable to holders who are "specified financial  institutions"
for  purposes  of the Tax Act, a holder  that is a  "financial  institution"  as
defined in the Tax Act for purposes of  mark-to-market  rules, or to a holder of
an interest that would be a "tax shelter investment" as defined in the Tax Act.

                  THIS  SUMMARY IS OF A GENERAL  NATURE ONLY AND IS NOT INTENDED
TO BE, AND SHOULD NOT BE CONSTRUED TO BE, LEGAL OR TAX ADVICE TO ANY  PARTICULAR
HOLDER.  ACCORDINGLY,  HOLDERS SHOULD CONSULT THEIR INDEPENDENT TAX ADVISERS FOR
ADVICE WITH RESPECT TO THE INCOME TAX CONSEQUENCES  RELEVANT TO THEIR PARTICULAR
CIRCUMSTANCES.

                  The following  applies to holders of Common Shares who are not
resident  in Canada for  purposes  of the Tax Act and who do not use or hold and
are not  deemed to use or hold  their  Common  Shares  in, or in the  course of,
carrying on a business in Canada.

                  Dispositions  of Common Shares.  A  non-resident  holder will,
upon a disposition or deemed  disposition  of Common  Shares,  not be subject to
taxation in Canada on any gain

                                      -8-
<PAGE>

realized on the disposition  unless the shares are "taxable  Canadian  property"
for the  purposes of the Tax Act and no relief is afforded  under an  applicable
tax convention between Canada and the country of residence of the holder.  Since
the Common Shares are listed on a prescribed  stock exchange for the purposes of
the Tax Act,  Common Shares held by a non-resident  holder will generally not be
"taxable  Canadian  property"  unless,  at any time during the five-year  period
immediately  preceding the disposition,  the non-resident  holder,  persons with
whom the non-resident  holder did not deal at arm's length,  or the non-resident
holder together with such persons, owned or had the right to acquire 25% or more
of the issued shares of any class of the capital of the Company. Any interest in
shares or options in respect of shares will be considered  to be the  equivalent
of ownership of such shares for purposes of the  definition of taxable  Canadian
property.

                  Non-residents   whose  shares  constitute   "taxable  Canadian
property"  will be subject to  taxation  in respect of a  disposition  or deemed
disposition  of Common  Shares on the same basis as  Canadian  residents  unless
otherwise  exempted  by an  applicable  tax  convention  between  Canada and the
country of residence of the holder.

                  Pursuant to the  Canada-United  States Income Tax  Convention,
1980 (the  "Convention"),  shareholders of the Company that are residents in the
United  States  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  disposition  of the  Common  Shares,  provided  the
principal  value of the Company is not  derived  from real  property  located in
Canada at the time of disposition.

                  Non-resident  holders  who might hold their  Common  Shares as
"taxable  Canadian  property" should consult their own tax advisers with respect
to the income tax consequences of a disposition of their Common Shares.

                  Non-resident  holders  whose  shares  are  repurchased  by the
Company,  except in respect of certain purchases made by the Company in the open
market, will be deemed to have received the payment of a dividend by the Company
in an amount  equal to the excess  paid over the  paid-up  capital of the Common
Shares so  purchased.  Such deemed  dividend  will be excluded from the holder's
proceeds of  disposition of such Common Shares for the purposes of computing any
capital  gain or loss but will be subject to Canadian  non-resident  withholding
tax in the manner described below under "Dividends."

                  Dividends.  Dividends  received  by a  non-resident  holder of
Common Shares will be subject to Canadian  withholding tax at the rate of 25% of
the  amount  thereof  unless  the rate is  reduced  under the  provisions  of an
applicable  tax  convention  between  Canada and the country of residence of the
holder.  The  provisions of the Convention  generally  reduce the rate to 15%. A
further  reduction to 5% under the Convention will be available if the recipient
is a company which owns at least 10% of the voting shares of the Company.

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

                                      -9-
<PAGE>

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.

                  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.  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 Shares,  except
as discussed elsewhere herein.

OTHER

                  The  foregoing is only a brief  description  of the rights and
limitations  of the  Company's  capital stock and is subject to and qualified by
reference to all applicable  provisions of the Business Corporations Act (Yukon)
and the Company's Articles.

                  CIBC Mellon Trust Company and ChaseMellon Shareholder Services
L.L.C. are co-transfer agents and co-registrars for the Common Shares.
