(P.O.  Box 2517,  Calgary,  Alberta,  Canada,  T2P 4P4),  or  deliver  it to the
chairman of the meeting prior to the commencement of the meeting.

         A  shareholder  who has given a proxy has the right to revoke it at any
time by an instrument  in writing  executed by the  shareholder  or his attorney
authorized in writing or, if the shareholder is a corporation,  by an officer or
attorney  thereof duly  authorized,  and deposited at the offices of CIBC Mellon

                          OUTSTANDING VOTING SECURITIES

         The Corporation has two classes of securities  outstanding  with voting
rights, Common Shares,  without nominal or par value (the "Common Shares"),  and
Series A  Convertible  Preferred  Shares,  without  nominal  or par  value  (the
"Preferred  Shares" and,  together with the Common Shares,  the  "Shares").  All
references  to Common  Shares  and per share  prices in the  Circular  have been
adjusted for the  one-for-five  reverse stock split in February 1998. On October
28, 1998, the Corporation had outstanding 6,119,707 Common Shares and 13,333,333
Preferred  Shares.  Each Common Share carries the right to one vote,  while each
Preferred  Share is entitled to one-fifth  of a vote.  The holders of the Common
Shares and the holders of the  Preferred  Shares will vote  together as a single
class at the meeting.

         The  Corporation has also reserved for issuance:  (i) 2,000,000  Common
Shares upon the exercise of share purchase warrants presently outstanding;  (ii)
172,408 Common Shares upon the conversion of convertible  subordinated notes due
August 1,  1999;  (iii)  2,666,666  Common  Shares  upon the  conversion  of the
Preferred  Shares;  and (iv) 2,085,000  Common Shares upon the exercise of stock
options presently outstanding held by employees, directors, and officers of, and
consultants to, the Corporation.

         Only  shareholders  of record at the close of  business  on October 28,
1998,  will be  entitled  to vote at the  meeting,  except to the extent  that a
shareholder  has  transferred  ownership  of any of his or her Common  Shares or
Preferred  Shares after the record date and the  transferee  of those shares has
produced properly endorsed share certificates or has otherwise  established that
he or she owns the shares and, in either  case,  has  requested,  not later than
December  5,  1998,  that  the  transferee's  name be  included  in the  list of
shareholders  entitled  to vote at the  meeting,  in which case such  transferee
shall be entitled to vote such shares at the meeting.

         The average of the high and low sale prices of the Common Shares on the
American Stock Exchange ("AMEX") on November 3, 1998, was $________.

                                VOTING OF PROXIES

         When  a  proxy  in the  accompanying  form  is  properly  executed  and
returned,  the Common  Shares or Preferred  Shares  represented  thereby will be
voted at the meeting in accordance with 

                                     - 2 -
<PAGE>

the  instructions  specified  in  the  spaces  provided  in  the  proxy.  IF  NO
INSTRUCTIONS  ARE  SPECIFIED,  THE SHARES  WILL BE VOTED IN FAVOR OF THE MATTERS
LISTED IN THE ACCOMPANYING NOTICE OF MEETING.

         A quorum of shareholders will be established at the meeting if not less
than 33-1/3% of the combined total of Common Shares and Preferred  Shares issued
and  entitled to vote at the meeting  are  present in person or  represented  by
proxy.

         A DIRECTION  TO ABSTAIN  WITH RESPECT TO PROPOSALS 1, 2 AND 5 SET FORTH
IN THE ACCOMPANYING  NOTICE OF MEETING WILL BE DEEMED TO HAVE THE SAME EFFECT AS
A VOTE AGAINST THE PROPOSAL.  Brokers holding Shares of record for customers may
not be  entitled  to vote unless they  receive  voting  instructions  from their
customers.  "Broker  non-votes,"  which  refer to Shares as to which a broker or
other nominee has  indicated on a duly executed and returned  proxy or otherwise
advised the Company that it lacks voting  authority as to any matter,  will have
no effect on the required vote on the matter.

         The enclosed form of proxy  confers  discretionary  authority  upon the
persons  named therein with respect to any  amendments to matters  identified in
the  accompanying  Notice of Meeting and other  matters that may  properly  come
before  the  meeting.  Management  is not  aware of any  amendments  to  matters
identified  in the  Notice of  Meeting  or of any other  matters  that are to be
presented for action at the meeting.

warrants or convertible securities within 60 days after October 28, 1998.

         13d-3(d)(1)  under the  Securities  Exchange  Act of 1934,  pursuant to
         which  Common  Shares  as to which a person  has the  right to  acquire
         beneficial  ownership  through the exercise or  conversion  of options,
         purchase  warrants  or  convertible  securities  within  60 days  after

         Shares  exercisable  within 60 days after  October  28,  1998,  held by
         Carissa Bennett, Gregory J. Frazer's wife.

ACQUISITION OF SECURITIES BY WARBURG, PINCUS VENTURES, L.P.

         On  December  24,  1997,  the  Corporation   consummated  the  sale  of
13,333,333 Preferred Shares, together with warrants to purchase 2,000,000 Common
Shares  for  $12.00 per share (the  "Warrants"),  contemplated  by a  Securities
Purchase Agreement dated November 21, 1997, between the Corporation and Warburg.
The  Preferred  Shares and Warrants were issued in exchange for  $18,000,000  in
cash from the liquid investment funds held by Warburg.

         The  Preferred  Shares,  which are  entitled to one-fifth of a vote per
share (or such other  number of votes equal to the number of Common  Shares into
which a Preferred Share shall be convertible  from time to time) in the election
of  directors  and  any  other  matters  presented  to the  shareholders  of the
Corporation  for action or  consideration,  represent  approximately  30% of the
outstanding  voting  securities of the Corporation.  Including the Common Shares
issuable   upon   exercise  of  the  Warrants,   Warburg   "beneficially   owns"
approximately 43% of the voting securities of the Corporation.

         The Preferred Shares may be converted at any time, in whole or in part,
into  Common  Shares.  The  conversion  rate is one Common  Share for every five
Preferred  Shares  surrendered for  conversion,  subject to adjustment for stock
dividends,  stock splits,  reverse stock  splits,  recapitalizations,  and other
anti-dilution adjustments.

<PAGE>

         As long as Warburg  beneficially  owns a number of  outstanding  Shares
constituting at least 10% of the outstanding  Common Shares  (including for this
purpose the Common Shares issuable upon  conversion of the Preferred  Shares but
not the Common Shares  issuable upon exercise of the Warrants),  the Corporation
is required,  upon Warburg's  request,  to nominate and use its reasonable  best
efforts  to  cause  to be  elected  and to  remain  as  directors  two  persons,
reasonably  satisfactory to the Corporation,  designated by Warburg. On December
24, 1997, in partial  satisfaction of this  requirement,  the Board elected Joel
Ackerman, a managing director of E. M. Warburg, Pincus & Co., LLC, as a director
of the  Corporation,  filling the vacancy  created by the resignation of Gene K.
Balzer, Ph.D. A second nominee designated by Warburg,  Haywood D. Cochrane, Jr.,
is  proposed  for  election as a director at the  meeting.  See "3.  Election of
Directors."

         The number of directors as to which  Warburg has the right to designate
nominees will increase to three if and for so long as the number of positions on
the  Board  exceeds  eight.   Such  number  will  decrease  by  one  if  Warburg
beneficially owns a number of outstanding  Shares  constituting less than 10% of
the  outstanding  Common  Shares and will  further  decrease  to none if Warburg
beneficially  owns less than 666,667  outstanding  Common Shares  (including for
purposes of the  foregoing the Common  Shares  issuable  upon  conversion of the
Preferred  Shares  but not the  Common  Shares  issuable  upon  exercise  of the
Warrants).  As long as Warburg  beneficially  owns at least 666,667  outstanding
Common Shares, the number of positions on the Board may not exceed 11. The right
to designate one nominee for director may be  transferred by Warburg to a single
purchaser of at least 6,666,667 Preferred Shares or that number of Common Shares
issuable upon conversion thereof.

         Prior to consummation of the transaction  with Warburg,  control of the
Corporation  was  effectively  in  the  hands  of the  Corporation's  directors,
particularly  Douglas F. Good,  Chairman of the Board,  and  Brandon M.  Dawson,
President and Chief Executive Officer, who together owned 20% of the outstanding
Common  Shares.  Messrs.  Good  and  Dawson  now  hold a total  of  12.4% of the
outstanding voting securities of the Corporation.

         As a result of Warburg's  significant  percentage share  ownership,  as
well as its right to designate nominees for director as discussed above, Warburg
will  be  able  to  exercise   substantial   influence   and  control  over  the
Corporation's  affairs.  For as  long as  Warburg  beneficially  owns  at  least
3,333,333  outstanding Preferred Shares (or the number of Common Shares issuable
upon conversion  thereof),  the Corporation may not, without Warburg's  consent,
(i) sell, lease,  exchange or transfer all or substantially all of its assets to
any third party,  (ii) amalgamate the Corporation with another  corporation such
that the then existing shareholders of the Corporation hold less than 51% of the
combined voting power of the amalgamated  corporation,  (iii) materially  change
the  nature  of  the   Corporation's   business,   (iv)  effect  a  liquidation,
amalgamation or sale of the Corporation or sell  substantially all of its or its
subsidiaries'  assets, or (v) with certain exceptions,  redeem or pay a dividend
or distribution on its Common Shares.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities  Exchange Act of 1934 ("Section 16(a)")
requires  that reports of  beneficial  ownership of Common Shares and changes in
such ownership be filed with the Securities and Exchange  Commission  ("SEC") by
"reporting  persons,"  including  directors,  executive  officers,  and  certain
holders of more than 10% of the outstanding  Common Shares. To the Corporation's
knowledge,   all  Section  16(a)  reporting  requirements  applicable  to  known
reporting  persons were complied with for transactions and stock holdings during
the fiscal  year ended  July 31,  1998,  except  that  Edwin J.  Kawasaki,  Vice
President-Finance and Chief Financial Officer of the Corporation, filed one late
report relating to the grant of an option for 6,000 Common Shares.

         event  that,  within  one year  (two  years in the case of Mr.  Dawson)
         following  a change in  control  of the  Corporation,  the  executive's
         employment is  terminated  by the  Corporation  without  cause,  or the
         executive  experiences  a material  demotion in status or position or a
         material change in his or her duties that is  inconsistent  with his or
         her position at the Corporation,  his or her base salary is reduced, or
         his or her participation in the Corporation's compensation plans is not
         continued on a level  comparable with other key executives (each of the
         foregoing events constitutes "good reason"). A change in control of the
         Corporation will be deemed to occur if (i) a person acquires beneficial
         ownership  of  50%  or  more  of  the  combined  voting  power  of  the
         Corporation,  with certain exceptions, (ii) the incumbent directors (or
         nominees approved by a majority of the incumbent  directors,  including
         subsequently  approved  directors)  cease  to  constitute  at  least  a
         majority   of  the   directors   of  the   Corporation,   or   (iii)  a
         reorganization,  amalgamation or sale of all or  substantially  all the
         assets of the Corporation,  with certain exceptions, is consummated.  A
         portion of Mr. Dawson's options will also become  exercisable  based on
         the time  elapsed  following  the date of grant in the  event  that his
         employment is terminated by the Company  without cause or by Mr. Dawson
         for "good reason."

(1)      The value shown was calculated  based on the excess of the closing sale
         price of the Common Shares  reported on AMEX on July 31, 1998, over the
         per share exercise price of the unexercised in-the-money options.

EMPLOYMENT AND CONSULTING AGREEMENTS

         In late 1997,  the Company  entered  into  employment  agreements  with
Brandon M. Dawson, its President and Chief Executive Officer, Edwin J. Kawasaki,
its  Vice   President-Finance  and  Chief  Financial  Officer,  and  Randall  E.
Drullinger, its Vice President-Marketing.  The term of each agreement expires on
December 24, 2001,  subject to automatic  one-year  extensions  annually  unless
either  party gives six  months'  prior  written  notice of  non-extension.  The
agreements establish an annual base salary of $195,000 for Mr. Dawson,  $115,000
for Mr.  Kawasaki,  and $104,000 for Mr.  Drullinger,  subject to such increases
(but  not  decreases)  as are  determined  from  time to time by the  Board or a
compensation  committee  designated  by the Board.  The  agreements  provide for
annual  incentive  bonuses  in an amount to be  determined  by the Board up to a
specified  percentage of each  executive's  base salary as follows:  Mr. Dawson,
100%; Mr. Kawasaki, 50%; and Mr. Drullinger, 50%. In addition, upon execution of
his agreement,  Mr. Kawasaki received a bonus for services performed in the 1997
fiscal year in the 

                                      - 9 -
<PAGE>

amount  of  $42,500.  Under the  agreements,  the  executives  are  entitled  to
participate  in all of the Company's  compensation  plans covering key executive
and managerial employees, including, without limitation, medical, disability and
life insurance benefits and vacation pay, as well as reimbursement for the lease
of an  automobile  up to $12,000 per year for Mr. Dawson and $6,000 per year for
each of Messrs.  Kawasaki  and  Drullinger.  The Company has also  provided  Mr.
Dawson with an equity  split-dollar  life insurance policy with a face amount of
$2,000,000,  provided  that the  premiums  paid by the Company per year will not
exceed $20,000, to be recovered from the death benefits, surrender value or loan
proceeds payable on the policy.

         The agreements with Messrs. Dawson, Kawasaki, and Drullinger include an
agreement  on the part of each  executive  not to compete with the Company for a
period  of two  years  (three  years  with  respect  to Mr.  Dawson)  after  the
executive's  employment  with the  Company  is  terminated.  If the  executive's
employment  is  terminated  by  reason  of death,  the  Company  will pay to the
executive's  personal  representative his base salary through the date of death,
together  with any accrued  benefits  (including  death  benefits)  to which the
executive is entitled under the terms of the Company's  compensation  plans.  In
the event of the executive's  termination due to disability,  the executive will
be entitled to receive his base salary  reduced by any  benefits  paid under the
Company's  group long-term  disability  insurance plan for the remaining term of
the agreement and the portion of his annual bonus  relating to the period before
his disability.  If the executive's  employment is terminated by the Company for
cause or the  executive  terminates  his  employment  voluntarily  without  good
reason, the Company will pay the executive his base salary through the effective
date of termination,  together with any accrued  benefits to which the executive
is entitled under the terms of the Company's  compensation plans. Cause includes
a material act of fraud,  dishonesty  or moral  turpitude,  gross  negligence or
intentional  misconduct.  Good  reason  includes  a  material  demotion  in  the
executive's  status  or  position,  a  material  change  in his  duties  that is
inconsistent with his position,  a reduction in his base salary, or a failure to
continue  his  participation  in  the  Company's  compensation  plans  on  terms
comparable to other key executives.  If the executive's employment is terminated
by the Company  without cause or by the executive with good reason,  the Company
will pay the  executive's  base salary  through the  termination  date,  plus an
amount  of  severance  pay  equal to,  with  respect  to  Messrs.  Kawasaki  and
Drullinger,  one  times  the  executive's  base  salary  payable  in 12  monthly
installments  and,  with  respect to Mr.  Dawson,  two times the sum of his base
salary and his average annual bonus for the prior two fiscal years payable in 24
monthly installments.  In addition,  upon such termination without cause or with
good reason,  the Company will afford  continued  participation in the Company's
compensation  plans (or, if not  permitted  under the general  provisions of any
such plan, will provide a substantially  equivalent  benefit) for two additional
years in the case of Mr. Dawson and for one year in the case of Messrs. Kawasaki
and Drullinger.

         Effective  January  1,  1997,  the  Company  entered  into a  five-year
consulting agreement with Hugh T. Hornibrook,  a director of the Company,  under
which the Company  pays Mr.  Hornibrook  a retainer of $__ per month and $__ per
hour for consulting services on an as-needed basis.

         From January 1, 1997,  until  September 30, 1998, the Company  retained
NeuroDynamic  Systems,  Inc.,  at the  rate of  $6,000  per  month,  to  provide
consulting services in connection with the Company's Canadian operations and the
development of a training  program

                                     - 10 -
<PAGE>

for  audiologists.  Gene K.  Balzer,  Ph.D.,  a director  of the  Company  until
December 1997, is president and sole shareholder of NeuroDynamic Systems, Inc.

         On October 31, 1996, the Company  entered into a three-year  employment
agreement with Kathy A. Foltner,  its Vice  President-Operations,  that provided
for a salary of $85,000 per year and certain employee benefits.  Effective March
27, 1998, Ms. Foltner's  annual salary was increased to $104,000.  The agreement
contains covenants not to compete with and not to solicit employees, clients, or
customers  of the  Company  during  her  period  of  employment  and for 36 full
calendar months following termination of her employment.

         On October 1, 1996,  the Company  entered  into a five-year  employment
agreement   with  Gregory  J.  Frazer,   Ph.D.,   its  Vice   President-Business
Development,  that  provides  for a base salary of  $110,000  per year and for a
bonus based on the aggregate net income of the hearing  clinics  acquired by the
Company that were  previously  owned,  in part, by Mr.  Frazer.  The  employment
agreement  provides Mr. Frazer with certain fringe  benefits such as medical and
dental insurance,  vacation,  professional  liability  insurance,  an automobile
allowance,  and reimbursement of certain  expenses.  Mr. Frazer has also entered
into an agreement with the Company which contains  covenants not to compete with
and not to solicit employees, clients or customers of the Company on behalf of a
competitor  during  his  period  of  employment  and for three  years  following
termination of his employment.

COMPENSATION OF DIRECTORS

         The non-employee  directors of the Corporation  receive a fee of $1,000
for  each  board  or  committee   meeting   attended  and  are   reimbursed  for
out-of-pocket  and travel  expenses  incurred in attending  board and  committee
meetings.  The Corporation has no other standard  arrangement  pursuant to which
directors  are  compensated  by the  Corporation  for  their  services  in their
capacity as directors.  The  Corporation may from time to time, as it has in the
past,  grant stock options to directors in accordance with the policies of AMEX,
the Securities and Exchange Commission,  and the securities laws and regulations
of the jurisdictions where the directors reside. Options granted during the 1998
fiscal year are included in the table under "Option Grants" above.

                 INTERESTS OF INSIDERS IN MATERIAL TRANSACTIONS

         On October 1, 1996, the Corporation acquired 11 hearing care clinics in
Southern  California through the acquisition of all of the outstanding shares of
three  companies  owned  by  Gregory  J.  Frazer,  Ph.D.,  who was  subsequently
appointed Vice President-Business Development and a director of the Corporation,
his wife,  Carissa  Bennett,  and Jami  Tanihana (the "HCA  Shareholders").  The
consideration paid by the Corporation  consisted of $314,724 in cash and 474,907
Common  Shares of which Mr. Frazer and Ms.  Bennett  received a total of 294,071
shares.  Mr. Frazer and Ms. Bennett also received a total of $196,294 in payment
for covenants not to compete.

         The HCA  Shareholders  have the right,  until  September  30, 2001,  to
require the  Corporation  to redeem an aggregate of 3,000 of their Common Shares
as of the last day of each

                                     - 11 -
<PAGE>

calendar  quarter  at a price of $8.35 per  share.  The  redemption  rights  are
noncumulative  and expire if not exercised as of the end of any calendar quarter
as to such quarter.  Pursuant to such  redemption  rights,  the  Corporation has
redeemed a total of 5,280 Common Shares from Ms.  Tanihana,  1,320 Common Shares
from Ms.  Bennett and 360 Common  Shares from Mr.  Frazer for  consideration  of
$44,089, $11,022, and $3,006, respectively.

         During 1997, the Corporation acquired six additional hearing clinics in
Southern  California in which Mr. Frazer was  part-owner.  Of the aggregate cash
purchase  price of $1,217,231  for the six clinics,  Mr. Frazer and Ms.  Bennett
received a total of $560,377.  Mr. Frazer and Ms.  Bennett also received the sum
of $147,654  in payment  for  covenants  not to compete in  connection  with the
acquisitions.  During 1998, the Corporation acquired three additional clinics in
California in which Mr. Frazer and Ms. Bennett were part-owners.  Mr. Frazer and
Ms. Bennett received $242,179 of the total purchase price of $542,268. They also
received $80,520 in payment for covenants not to compete.

         On October 31, 1996, the Corporation  acquired the Midwest  Division of
Hearing  Health  Services,  Inc.  (the  "Midwest  Division"),  in  exchange  for
convertible  subordinated notes made payable to certain affiliates of the seller
in the aggregate  amount of $2,600,000,  convertible into 400,000 Common Shares,
and the  assumption of a promissory  note with a balance of $360,000  payable to
Kathy A. Foltner, Vice  President-Operations of the Company. The promissory note
is payable in equal annual  installments of $120,000  beginning on July 1, 1997,
and bears interest at 6% per annum.  The balance of the promissory  note at July
31,  1998,  was  $120,000 and the highest  outstanding  balance  during the 1998
fiscal year was $240,000.  In addition to the promissory  note, the  Corporation
also agreed to assume an obligation of the Midwest  Division to pay Ms.  Foltner
$50,000 in each of 1997, 1998, and 1999, if specified production goals were met.
The  Corporation  paid Ms. Foltner $50,000 during the fiscal year ended July 31,
1998, and $12,500 for the period from August 1, 1998, to October 31, 1998.

         Under the terms of an escrow  agreement  dated January 14, 1994,  among
the Corporation,  Michael G. Thomson,  Craig R. Thomson,  Murray T.A.  Campbell,
Bruce A. Ramsay and William DeJong (the "Founding Shareholders"), and a trustee,
600,000 Common Shares were issued to the Founding  Shareholders  in exchange for
an aggregate of $100,000 in cash and deposited in escrow with the trustee. As of
October 21, 1997, all of the shares had been released from escrow.

         Douglas F. Good, Marilyn Marshall, and Trudy McCaffery (the "Fraserview
Shareholders"),  the Corporation, and a trustee entered into an escrow agreement
dated October 7, 1994,  with respect to 850,000 Common Shares (the  "Performance
Shares") that were issued to the Fraserview  Shareholders in connection with the
Corporation's acquisition of Fraserview Hearing & Speech Clinic Ltd. Pursuant to
a purchase and sale agreement (the "Share Purchase Agreement") dated as of April
15, 1996,  between the Fraserview  Shareholders and Brandon M. Dawson,  Roger W.
Larose,  Randall E. Drullinger and Hugh T. Hornibrook  (the  "Purchasers"),  the
Fraserview Shareholders sold all of the Performance Shares to the Purchasers for
an aggregate consideration of $601,637 (converted from Canadian dollars at April
15, 1996).  Pursuant to an assignment and novation  agreement dated as of August
28, 1996,  Roger W. Larose assigned all of his right,  title and interest in the
Share Purchase Agreement to Brandon M.

                                     - 12 -

Dawson. In addition,  pursuant to an assignment and novation  agreement dated as
of February 27, 1997,  Mr.  Hornibrook  assigned  all of his right,  title,  and
interest in the Share Purchase  Agreement to Edwin J.  Kawasaki.  As a result of
the Share Purchase  Agreement and assignments,  Messrs.  Dawson,  Drullinger and
Kawasaki hold 780,000, 50,000 and 20,000 Performance Shares,  respectively.  The
Performance Shares were released from escrow effective February 11, 1998.

         William  DeJong,  a director  of the  Corporation,  is a partner in the
Calgary, Alberta law firm of Ballem MacInnes.  During the fiscal year ended July
31, 1998,  total fees,  disbursements  and  government  sales tax paid to Ballem
MacInnes by the Corporation for legal services were approximately $196,000.

         Under a  settlement  agreement  between  the  Corporation  and Roger W.
Larose,  formerly the  Corporation's  chief operating  officer,  the Corporation
agreed to pay the exercise  price of 40,000  options to purchase  Common  Shares
held by Mr. Larose.  On April 1, 1996, Mr. Larose  exercised  options for 20,000
Common  Shares at $1.40 per share and  Douglas F. Good,  as an advance to and on
behalf  of  the  Corporation,   paid  the  exercise  price  of  $28,048  to  the
Corporation.  On  September  30,  1996,  Mr.  Larose  exercised  options  for an
additional  20,000  Common Shares at $1.40 per share and Mr. Good, as an advance
to and on behalf of the  Corporation,  paid the exercise price of $27,900 to the
Corporation.

         Brandon M. Dawson  subsequently  executed  promissory notes in favor of
Mr.  Good equal to the  amounts  advanced  by Mr.  Good in  connection  with the
options exercised by Mr. Larose,  and Mr. Dawson was substituted for Mr. Good as
the obligee with respect to such advances.  Interest on the advances  accrued at
the  rate  of 9%  per  annum.  The  advances  were  repaid  to Mr.  Good  by the
Corporation  on December 26, 1997,  along with interest in the amount of $7,147,
thereby satisfying Mr. Dawson's obligations to Mr. Good.

         On October 5,  1997,  the  Corporation  loaned  Mr.  Dawson  $85,000 in
connection with the purchase of his residence.  The loan was repaid on April 10,
1998, along with interest at 10% per annum in the amount of $4,308.

         On December 26, 1997,  the  Corporation  loaned Mr.  Dawson  $30,639 in
order to allow Mr. Dawson to repay an advance from Mr. Good in  connection  with
the exercise by Mr. Dawson of options to purchase  20,000 Common Shares on April
1, 1996.  On March 19, 1998,  the  Corporation  loaned Mr.  Dawson an additional
$34,298 in order to pay taxes  incurred as a result of Mr.  Dawson's  April 1996
option  exercise.  The  loans  bear  interest  at 7.75% per annum and are due on
November 1, 1999.

         On May 8, 1997, Mr. Dawson  exercised  options for 50,000 Common Shares
at $1.35 per share in order to allow  options for Common Shares to be granted to
other employees.  In connection with such exercise,  the Corporation  loaned Mr.
Dawson  $67,500 to pay the aggregate  exercise  price of the options.  The loan,
which bears interest at 10% per annum,  is due on November 1, 1999. On April 24,
1998, the  Corporation  loaned Mr. Dawson an additional  $91,000 in order to pay
taxes  incurred  as a result  of Mr.  Dawson's  May 1997  option  exercise.  The
additional  loan bears  interest  at 7.75% per annum and is due on  November  1,
1999.

Additional  copies of the  annual  report  may be  obtained  by  writing  to the

                     AUDITORS, TRANSFER AGENT AND REGISTRAR

         The auditors of the  Corporation  are KPMG Peat Marwick LLP,  1211 S.W.

Shareholder  Services L.L.C., 520 Pike Street,  Suite 1220, Seattle,  Washington
98101.

                     PARTICULARS OF MATTERS TO BE ACTED UPON

         To the  knowledge  of the Board of  Directors,  the only  matters to be
acted upon at the annual meeting are those set forth in the accompanying  Notice
of Meeting relating to the continuance of the Corporation to the jurisdiction of
the Yukon  Territories,  fixing  the  number of  directors  to be  elected,  the
election of directors, the appointment of auditors,  approved of an amendment to
the Corporation's Stock Award Plan, and the receipt of the financial  statements
for fiscal 1998.

1.       APPROVAL OF CONTINUANCE TO THE YUKON TERRITORIES

         The Board of Directors believes that it is in the best interests of the
Corporation and its  shareholders to change the jurisdiction of incorporation of
the  Corporation  from  Alberta  to  the  Yukon  Territories  (the  "Continuance
Proposal").  Accordingly, the shareholders of the Corporation are being asked to
vote on a special resolution, unanimously approved by the Board of Directors, to
approve and authorize the  Corporation  to continue to the  jurisdiction  of the
Yukon Territories under the Business  Corporations Act (Yukon  Territories) (the
"Yukon Act") as if the Corporation had been  incorporated  under the laws of the
Yukon Territories.  SHAREHOLDERS ARE URGED TO READ CAREFULLY THIS SECTION OF THE
CIRCULAR,  INCLUDING THE RELATED SCHEDULES REFERENCED BELOW AND ATTACHED HERETO,
BEFORE VOTING ON THE CONTINUANCE PROPOSAL.

         Management is proposing that the  Corporation  continue under the Yukon
Act  principally  because  the Yukon Act does not contain a  requirement  that a
majority of the directors of the  Corporation be resident  Canadians.  Under the
Business  Corporations  Act  (Alberta)  (the  "Alberta  Act"),  under  which the
Corporation  is  currently  governed,  at  least  half of the  directors  of the
Corporation must be resident  Canadians and directors may not transact  business
at a meeting of  directors  unless at least half of the  directors  present  are
resident Canadians. Management of the Corporation has determined that continuing
under the  Yukon  Act will  allow  the  Corporation  to seek the most  qualified
persons to act as directors,  irrespective  of their place of residence.  As the
Corporation  is rapidly  expanding  its  business and  operations  in the United
States, this flexibility

                                     - 14 -
<PAGE>

is of particular  importance.  In all other material respects, the Yukon Act and
the Alberta Act are comparable.

         The  Continuance  Proposal  will not  result in any change in the name,
business, management, fiscal year, assets or liabilities, or headquarters of the
Corporation.  The capital structure of the Corporation following  implementation
of the  Continuance  Proposal also will be unchanged.  SHAREHOLDERS  WILL NOT BE
REQUIRED  TO SEND IN THEIR STOCK  CERTIFICATES  FOR COMMON  SHARES OR  PREFERRED
SHARES,  WHICH WILL CONTINUE TO REPRESENT  ISSUED AND OUTSTANDING  SHARES OF THE
CORPORATION.  The  Common  Shares  will  continue  to be traded on AMEX  without
interruption, under the same symbol (SSN).

         Management  of the  Corporation  believes that  continuation  under the
Yukon Act will not materially adversely affect the rights of the shareholders of
the  Corporation or the conduct of the business and affairs of the  Corporation.
There are no adverse U.S. or Canadian income tax consequences to the Corporation
or its shareholders as a result of implementation of the Continuance Proposal.

         The  Continuance  Proposal is not being proposed in order to prevent an
unsolicited  takeover  attempt,  and the Board of  Directors is not aware of any
present  attempt  by any person to acquire  control of the  Corporation,  obtain
representation on the Board of Directors (other than Warburg, as described under
"Acquisition of Securities by Warburg,  Pincus Ventures,  L.P." above),  or take
any action that would materially affect the governance of the Corporation.

         The continuance of the Corporation under the Yukon Act will involve the
filing of Articles of Continuance, in the form prescribed by the Yukon Act, with
the  Registrar  of  Corporations  (Yukon  Territories),  which will  replace the
Corporation's current Articles. The Yukon Act also requires the establishment of
a registered office and a records office in the Yukon Territories.  The Articles
of  Continuance  are in all material  respects  identical to the Articles of the
Corporation as they currently exist, with the necessary modifications to conform
to the Yukon Act.

         For the continuance to occur,  the special  resolution  authorizing the
Corporation to continue under the Yukon Act must be passed,  pursuant to Section
182 of the  Alberta  Act,  by at least  two-thirds  of the votes cast in respect
thereof by holders of the Corporation's shares at the meeting. Additionally, the
continuance  under  the  Yukon  Act  must  be  authorized  by the  Registrar  of
Corporations (Alberta).  The Registrar of Corporations (Alberta) has advised the
Corporation, by letter dated September 11, 1998, that it has no objection to the
Corporation's  continuing  to  the  Yukon  Territories.   Even  if  the  special
resolution is passed and all  regulatory  approvals are given,  the directors of
the Corporation may, in their sole discretion, revoke the special resolution if,
for example,  the number of shares with respect to which  Notices of Dissent are
given is, in the opinion of the directors, unduly detrimental to the Corporation
or its shareholders.

         Subject to the Continuance  Proposal being approved and  implementation
of the  continuance  of the  Corporation  under the Yukon Act, new bylaws of the
Corporation have been approved by the directors of the Corporation and are being
submitted  for  ratification  by  the  shareholders  of the  Corporation  at the
meeting.  Bylaw No. 1C of the  Corporation,  attached  hereto as  Schedule A, is
similar to the existing Bylaw No. 1A (as amended by Bylaw No. 1B) in

                                     - 15 -
<PAGE>

all  material  respects  and is  required to replace  the  existing  bylaws upon
implementation of the Continuance Proposal in order to conform with the language
of the Yukon Act.

TEXT OF THE SPECIAL RESOLUTION

         The  complete  text  of the  special  resolution  to be  submitted  for
approval by the shareholders at the meeting is as follows:

         "BE IT RESOLVED as a Special Resolution of the Corporation that:

1.       The continuance of the Corporation under the Business  Corporations Act
         (Yukon  Territories)  (the "Yukon Act") as if the  Corporation had been
         incorporated thereunder is hereby approved;

2.       The  Corporation  is hereby  authorized  to apply to the  Registrar  of
         Corporations   (Alberta)   for   approval  to  continue  to  the  Yukon
         Territories under the Yukon Act;

3.       The  Corporation  is hereby  authorized  to apply to the  Registrar  of
         Corporations  (Yukon  Territories)  for a  Certificate  of  Continuance
         continuing  the  Corporation  under  the  Yukon  Act as if it had  been
         incorporated  thereunder  and to file with such  Registrar  Articles of
         Continuance  and such other documents as may be required in the form or
         forms  prescribed by the Yukon Act, and continue,  and effective on the
         issuance of a Certificate  of Continuance by such Registrar and without
         affecting the validity and existence of the Corporation by or under its
         Articles and the validity of any act performed thereunder, the Articles
         of the Corporation shall be amended to conform to the laws of the Yukon

DISSENTING SHAREHOLDERS' RIGHTS

         Under Section 184 of the Alberta Act,  shareholders  of the Corporation
have the right to dissent from the  Continuance  Proposal in accordance with the
provisions of such section.  Any  shareholder of the Corporation who dissents in
respect of the  Continuance  Proposal  in  compliance  with  Section  184 of the
Alberta  Act (a  "Dissenting  Shareholder")  will be  entitled to be paid by the
Corporation  the  fair  value  of the  shares  of the  Corporation  held by such
shareholder,  such fair value to be  determined  at the close of business on the
last  business  day  before  the day on which  the  resolution  from  which  the
Dissenting  Shareholder  dissents  is adopted.  In order to exercise  his or her
right to  dissent,  a  Dissenting  Shareholder  must send to the  Corporation  a
written  objection to the Continuance  Proposal at or before the meeting,  which
will be held on December 15, 1998,  at 10 a.m.,  Pacific  Time.  Failure to vote
against the special  resolution does not act as a waiver of the right of dissent
and  appraisal,  and a vote against the special  resolution  does not constitute
notice of dissent. A summary of the provisions of Section 184 of the Alberta Act
and the full text of the provisions are attached hereto as Schedule B.

         The  Continuance  Proposal  will not take  effect  unless  the  special
resolution is approved by at least 66-2/3% of the votes cast by the shareholders
on the motion at the meeting and  confirmed by the issuance by the  Registrar of
Corporations  (Alberta) under the Alberta Act of a Certificate of Discontinuance
of the Corporation. Warburg and management, which together control approximately
47% of the voting shares of the  Corporation,  have indicated their intention to
vote in  favor  of the  Continuance  Proposal.  THE  PERSONS  DESIGNATED  IN THE
ENCLOSED  FORM OF PROXY,  UNLESS  OTHERWISE  INSTRUCTED,  INTEND TO VOTE FOR THE
SPECIAL RESOLUTION APPROVING THE CONTINUANCE PROPOSAL.

         THE  BOARD  RECOMMENDS  THAT  SHAREHOLDERS  VOTE  FOR  THE  CONTINUANCE
PROPOSAL.

2.       FIXING NUMBER OF DIRECTORS

         Under the Articles of Incorporation,  as amended (the  "Articles"),  of
the Corporation,  the Board of Directors may consist of a minimum of three and a
maximum of 11 directors.  The Board of Directors  may,  between  annual  general
meetings,  appoint  one or more  additional  directors  to serve  until the next
annual general meeting, provided that the number of additional directors may not
exceed  one-third of the number of directors  elected at the most recent  annual
general meeting and the total number of directors may not exceed 11.

         At  present,  the Board of  Directors  consists  of six  directors.  As

as directors  at the meeting.  Accordingly,  the  shareholders  will be asked to
consider and, if thought fit, to pass the following resolution:

                                     - 17 -
<PAGE>

              "BE IT RESOLVED THAT the number of directors of the Corporation be
         and the same is hereby  fixed at six  directors  until such time as the
         directors  determine by  resolution  to appoint one or more  additional
         directors in accordance with the Corporation's Articles."

         The foregoing  resolution  will be adopted if approved by a majority of
the votes cast on this motion by the  shareholders  at the meeting.  THE PERSONS
DESIGNATED IN THE ENCLOSED FORM OF PROXY, UNLESS OTHERWISE INSTRUCTED, INTEND TO
VOTE FOR THE RESOLUTION FIXING THE NUMBER OF DIRECTORS.

3.       ELECTION OF DIRECTORS

         The Board of  Directors  has  nominated  six  persons  for  election as
directors  to serve  until the next  annual  general  meeting  and  until  their
successors  are elected and  qualified.  Five of the  nominees  for  election as
directors are members of the present  Board.  Joel Ackerman was appointed to the
Board  in  December  1997 at the  request  of  Warburg,  the  holder  of all the
outstanding  Preferred Shares, and Haywood D. Cochrane,  Jr., has been nominated
for election at the meeting at the request of Warburg, conditional upon approval
of the  Continuance  Proposal.  See "1.  Approval  of  Continuance  to the Yukon
Territories." In the event that the Continuance  Proposal is not approved by the
required  two-thirds  vote,  following the meeting,  Mr.  Cochrane will not take
office as a director  and the Board  will  appoint  Douglas  F. Good,  a private
investor,  to fill the resulting vacancy.  Mr. Good, age 56, has been a director
of the  Corporation  since 1994 and has served as  Chairman  of the Board  since
August 1996. From December 1995 until July 1996, he served as the  Corporation's
chief financial  officer.  He was President of the Corporation from October 1994
to December 1995. Prior to October 1994, Mr. Good was chief financial officer of
International  Retail Systems Inc., a software and point of sale systems company
based in Dallas, Texas.

         A nominee  will be elected if the nominee  receives a plurality  of the
votes cast by the Common Shares entitled to vote in the election,  provided that
a quorum is present at the meeting.  UNLESS  AUTHORITY TO VOTE FOR A DIRECTOR OR
DIRECTORS IS WITHHELD,  THE ACCOMPANYING PROXY WILL BE VOTED FOR THE ELECTION OF
THE  NOMINEES  NAMED  BELOW.  If for some  unforeseen  reason a nominee  becomes
unavailable  to serve as a  director,  the Board of  Directors  may  designate a
substitute nominee. In that case, the persons named as proxies will vote for the
substitute nominee designated by the Board unless otherwise instructed.

         The following table sets forth  information with respect to each person
nominated for election as a director of the Corporation,  including their names,
municipality  of  residence,  ages as of October 28, 1998,  business  experience
during the past five years, and year of appointment as a director.  There are no
family relationships among the Corporation's  directors,  nominees for director,
or officers.

discharge,  and reviews with management and the independent  auditors the annual

Audit  Committee met once during fiscal 1998. The members of the Audit Committee

         The  Corporation  presently  does  not  have  a  standing  compensation

         Kathy A. Foltner,  age 45, was appointed Vice  President-Operations  of
the Corporation in November 1996, when the  Corporation  acquired  substantially
all of the assets of the Midwest Division of Hearing Health  Services,  Inc. Ms.
Foltner served as vice president of Hearing Health Services, Inc., since January
1995 and as director of its Michigan operations from July 1994 to December 1994.
Prior to July 1994, Ms. Foltner was the owner and president of  Audio-Vestibular
Testing Center, Inc.

         Edwin J.  Kawasaki,  age 40, has served as Vice  President-Finance  and
Chief Financial Officer of the Corporation since August 1996. Mr. Kawasaki was a
principal of Stafford Capital Corp., an investment  buy-out firm, from September

4.       APPOINTMENT OF AUDITORS

Effective  December 20, 1996, upon the  recommendation of the Board of Directors
and approval by the shareholders, the Corporation retained KPMG Peat Marwick LLP
as its independent auditors, replacing Shikaze Ralston. The Corporation made the
change in independent  auditors due to its significant and growing operations in
the United  States and its need to draw upon the  services  and  expertise  of a
large international  accounting and auditing firm. The report of Shikaze Ralston
on the consolidated  financial  statements of the Corporation for the year ended
July 31, 1996,  included in its 1997 annual  report on Form 10-K did not contain
an  adverse  opinion  or  disclaimer  of  opinion  and was not  qualified  as to
uncertainty,  audit scope, or accounting principles.  In addition, there were no
disagreements  with Shikaze  Ralston on any matter of  accounting  principles or
practices, financial statement disclosure, or auditing scope or procedure, which
disagreements,  if not resolved to the  satisfaction of Shikaze  Ralston,  would
have caused them to make reference to the subject matter of the disagreements in
connection  with their report.  Before engaging KPMG Peat Marwick LLP as its new
independent  auditors,  the  Corporation did not consult with them regarding any
matters related to the application of accounting  principles,  the type of audit
opinion that might be rendered on the Corporation's  financial statements or any
other such matters.

         UNLESS OTHERWISE INSTRUCTED,  THE PERSONS NAMED IN THE ENCLOSED FORM OF
PROXY INTEND TO VOTE FOR THE APPOINTMENT OF KPMG PEAT MARWICK LLP AS AUDITORS OF
THE  CORPORATION  TO HOLD  OFFICE  UNTIL  THE NEXT  ANNUAL  GENERAL  MEETING  OF
SHAREHOLDERS OR UNTIL THEIR  SUCCESSORS ARE APPOINTED AND TO AUTHORIZE THE BOARD
OF  DIRECTORS  TO  FIX  THE  AUDITORS'  REMUNERATION.  The  Corporation  expects
representatives  of KPMG Peat Marwick LLP to be present at the meeting and to be
available  to respond  to  appropriate  questions.  The  auditors  will have the
opportunity to make a statement at the meeting if they desire to do so.

year  following a change in control of the  Corporation  (as defined),  and will
expire 10 years following the date of grant.

DESCRIPTION OF AWARDS UNDER THE STOCK AWARD PLAN

         The types of awards (collectively  referred to as "Awards") that may be
granted by the Board under the Stock Award Plan include:

         Options.  Options to  purchase  Common  Shares may be  incentive  stock
options ("ISOs")  meeting the  requirements of Section 422 of the U.S.  Internal
Revenue Code of 1986, as amended (the "Code"), or nonqualified options which are
not eligible for such tax-favored treatment.  The expiration date of each option
is as  determined  by the Board  (but not more  than 10 years  after the date of
grant  for  ISOs),  subject  to  approval  by any  regulatory  authority  having
jurisdiction  over Awards granted under the Stock Award Plan. The exercise price
per share must be equal to or greater  than 100% of the fair  market  value of a
Common Share on the date the option is granted for ISOs and at a discount of not
more than 25% from such fair market value for nonqualified options.

         Stock  Appreciation  Rights. A recipient of stock  appreciation  rights
will receive upon exercise an amount equal to the excess (or  specified  portion
thereof) of the fair market value of a

                                     - 23 -
<PAGE>

Common  Share on the date of  exercise  over the base price,  multiplied  by the
number of shares as to which the  rights are  exercised.  The base price will be
designated  by the Board in the award  agreement  and may be equal to, higher or
lower  than the fair  market  value of the  Common  Shares on the date of grant.
Payment may be in cash, in Common Shares, or in any other form or combination of
methods approved by the Board.

         Restricted  Units.  Restricted  units are awards of units equivalent in
value to a Common  Share,  which may be subject to  forfeiture  if the recipient
terminates  employment or service as a director or consultant during a specified
period. At the expiration of such period,  the restricted units vest and payment
is made in an amount  equal to the value of the number of shares  covered by the
restricted units. Payment may be in cash, in Common Shares, or in any other form
or combination of methods approved by the Board.

         Performance Awards.  Performance Awards are granted in units equivalent
in value to a Common Share.  A performance  Award is subject to forfeiture if or
to the extent the  recipient  fails to meet certain  performance  goals during a
designated performance cycle. Performance Awards earned by attaining performance
goals are paid at the end of a performance  cycle in cash, in Common Shares,  or
in any other form or combination of methods approved by the Board.

         Other Stock-Based Awards. The Board may grant other Awards that involve
payments or grants of Common  Shares or are measured by or in relation to Common
Shares.  The Stock  Award  Plan  provides  flexibility  to  design  new types of
stock-based or stock-related  Awards to attract and retain employees,  officers,
directors, and outside advisers in a competitive environment.

         Nontransferability. Awards are not transferable or assignable except by
will or the laws of descent and distribution.

ADJUSTMENTS FOR CHANGES IN CAPITALIZATION

         In the event of a change in  capitalization,  the Board  will make such
proportionate  adjustments  in the  aggregate  number of Common Shares for which
Awards may be granted under the Stock Award Plan,  the maximum  number of Common
Shares which may be awarded to any participant,  and the number of Common Shares
covered by, and the exercise or base price of, any  outstanding  Awards,  as the
Board in its sole discretion deems appropriate.

DURATION, TERMINATION AND AMENDMENT OF THE STOCK AWARD PLAN

         The Stock  Award  Plan will  remain in effect  until  Awards  have been
granted  covering all available  Common Shares under the Stock Award Plan or the
plan is otherwise  terminated  by the Board.  The Board may  terminate the Stock
Award Plan at any time, but any such termination will not affect any outstanding
Awards. The Board may also amend the Stock Award Plan from time to time, subject
to  approval,  to the  extent  required,  by  any  regulatory  authority  having
jurisdiction  over  the  Stock  Award  Plan,  but may not,  without  shareholder
approval,  materially 

                                     - 24 -

increase  the  aggregate  number of Common  Shares that may be issued  under the
Stock  Award Plan  other than in  connection  with  adjustments  for a change in
capitalization.

U.S. FEDERAL INCOME TAX CONSEQUENCES OF AWARDS

         The following  discussion  summarizes  the principal  anticipated  U.S.
federal income tax  consequences  of grants of Awards under the Stock Award Plan
to participants and to the Corporation. All recipients of Awards under the Stock
Award Plan to date are U.S. residents.

                        TAX CONSEQUENCES TO PARTICIPANTS

         Incentive  Stock Options.  ISOs under the Stock Award Plan are intended
to meet the  requirements  of Section 422 of the Code.  A  participant  does not
realize  taxable  income upon the grant of an ISO or upon the issuance of shares
when the  option  is  exercised.  The  amount  realized  on the sale or  taxable
exchange of such shares in excess of the exercise  price will be a capital gain,
and any loss will be a capital  loss,  except  that if such  disposition  occurs
within one year after  exercise  of the option or two years  after  grant of the
option, the participant will recognize  compensation  taxable at ordinary income
tax rates  measured  by the  amount by which the  lesser of (i) the fair  market
value on the date of  exercise  or (ii) the amount  realized  on the sale of the
shares,  exceeds the exercise  price.  For purposes of  determining  alternative
minimum taxable income, an ISO is treated as a nonqualified option.

         Nonqualified Options. No taxable income is recognized upon the grant of
a nonqualified option. In connection with the exercise of a nonqualified option,
a participant will generally  realize ordinary income measured by the difference
between the exercise  price and the fair market value of the shares  acquired on
the date of exercise. The participant's cost basis in the acquired shares is the
fair market value of the shares on the exercise  date. Any gain upon sale of the
shares is capital gain.

         Stock Appreciation Rights. The grant of a stock appreciation right to a
participant  will not cause the recognition of income by the  participant.  Upon
exercise of a stock appreciation  right, the participant will recognize ordinary
income  equal to the  amount of cash  payable to the  participant  plus the fair
market  value  of  any  Common  Shares  or  other  property   delivered  to  the
participant.

         Restricted Units and Performance Awards.  Generally, a participant will
not  recognize  any income  upon  issuance  of an Award of  restricted  units or
performance units that is subject to forfeiture  during a restriction  period or
performance cycle.  Generally,  a participant will recognize compensation income
upon the vesting of restricted units or performance  units in an amount equal to
the amount of cash  payable to the  participant  plus the fair  market  value of
Common Shares or other property delivered to the participant.

                       TAX CONSEQUENCES TO THE CORPORATION

         To the extent  participants  qualify for capital gains  treatment  with
respect to the sale of shares  acquired  pursuant  to  exercise  of an ISO,  the
Corporation  will not be entitled to any tax deduction in connection  with ISOs.
In all other cases,  the Corporation  will be entitled to receive a U.S. federal
income tax deduction at the same time and in the same amount as the amount which
is taxable to participants as ordinary income with respect to Awards.

RECOMMENDATION AND VOTE

         At the  meeting,  the  shareholders  will be asked to consider  and, if
thought fit, to approve the following resolution:

              "BE IT  RESOLVED  THAT the  amendment  of the Second  Amended  and
         Restated Stock Award Plan of the  Corporation to increase the number of
         Common Shares issuable  thereunder  from 1,800,000 to 2,300,000  Common
         Shares is hereby approved."

         THIS  RESOLUTION  WILL NOT TAKE  EFFECT  UNLESS IT IS  APPROVED  BY THE
AFFIRMATIVE VOTE OF THE HOLDERS OF AT LEAST A MAJORITY OF THE SHARES PRESENT, IN
PERSON OR BY PROXY,  AND ENTITLED TO VOTE ON THE  PROPOSAL AT THE  MEETING.  THE
PERSONS DESIGNATED IN THE ENCLOSED FORM OF PROXY,  UNLESS INSTRUCTED  OTHERWISE,
INTEND TO VOTE FOR THIS RESOLUTION APPROVING AMENDMENT OF THE STOCK AWARD PLAN.

         THE BOARD RECOMMENDS THAT  SHAREHOLDERS VOTE IN FAVOR OF APPROVAL OF AN
AMENDMENT  TO THE STOCK  AWARD  PLAN TO  INCREASE  THE  NUMBER OF COMMON  SHARES
ISSUABLE THEREUNDER TO 2,300,000 COMMON SHARES.

                  SHAREHOLDER PROPOSALS FOR 1999 ANNUAL MEETING

         Shareholder  proposals  submitted  for  inclusion  in  the  1999  proxy
materials and  consideration  at the 1999 annual general meeting of shareholders
must be received by the  Corporation by July 15, 1999. Any such proposal  should
comply  with the SEC's  rules  governing  shareholder  proposals  submitted  for
inclusion in proxy materials.

         The persons  named as proxies for the 1999  annual  general  meeting of
shareholders will have  discretionary  authority to vote on any matter presented
by a  shareholder  for action at such meeting  unless the  Corporation  receives
notice of the matter by September  28, 1999, in which case such persons will not
have  discretionary  voting  authority  except as  provided  in the SEC's  rules
governing shareholder proposals.

    foregoing shall be deemed to have been communicated:

         (i)  if given or made by mail, at the time it would be delivered in the

         ---------------------------------------- 
resolution in writing  signed by all the  Shareholders  entitled to vote on that
resolution at a Meeting of  Shareholders is as valid as if it had been passed at
a Meeting of  Shareholders.  A resolution in writing may be signed in any number
of  counterparts  which  together shall be construed as a single  instrument.  A
resolution  in writing  shall take effect on the date when it is expressed to be
effective notwithstanding that the effective date is before or after the date on
which it was signed by the  Shareholders or any of them. A resolution in writing
transmitted  by  telegraph,  telex or other  device  capable of  transmitting  a
printed  message and purporting to be sent by a Shareholder  shall be valid as a
counterpart of a resolution in writing of the Shareholders.

                                 LIEN ON SHARES

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

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


                                     PART 6
                          SHARES AND SHARE CERTIFICATES

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

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

6.03     Non-Recognition  of Trusts:  Subject to the  provisions of the Act, the
         --------------------------
Corporation  may treat the  person in whose  name a share is  registered  in the
securities  register  as the  absolute  owner of the share as if that person had
full  legal  capacity  and  authority  to  exercise  all  rights  of  ownership,
irrespective  of any indication to the contrary  through  knowledge or notice or

<PAGE>
                                       12

description in the Corporation's records or on the share certificate.

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

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

6.06     Joint  Shareholders:  If two or more  persons are  registered  as joint
         -------------------
holders of any

<PAGE>
                                       13

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

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

6.08     Transfer and  Transmission of Shares:  Shares of the Corporation may be
         ------------------------------------
transferred  in  the  form  of  a  transfer  of  endorsement   endorsed  on  the
certificates issued for the shares of the Corporation or in any form of transfer
which may be approved by the Board.

6.09     Registration  of  Transfer:  Subject to the  provisions  of the Act, no
         --------------------------
transfer of shares  shall be  registered  in a securities  register  except upon
presentation  of the  certificate  representing  such  shares  with  a  transfer
endorsed thereon or delivered  therewith duly executed by the registered  holder
or by his attorney or successor duly  appointed,  together with such  reasonable
assurance or evidence of signature,  identification and authority to transfer as
the Board may from time to time prescribe,  upon payment of all applicable taxes
and any fees prescribed by the Board.

6.10     Rights  of  Representatives:  The  Corporation  may treat a person as a
         ---------------------------
registered  Shareholder  entitled to exercise all rights of the  Shareholder  he
represents if that person produces

<PAGE>
                                       14

to the  Board  such  evidence  as  may be  reasonably  required  that  he is the
executor, administrator, heir or legal representative of the heirs of the estate
of a deceased  Shareholder,  or a guardian,  committee or trustee representing a
registered Shareholder.

6.11     No Duty to Third  Person:  The  Corporation  is not required to enquire
         ------------------------
into the existence of, or see to the performance or observance of, any duty owed
to a third person by a registered holder of any of its shares, or by anyone whom
it treats, subject to the Act, as the owner or registered holder of its shares.

6.12     Transfer Agents and Registrars: The Board may from time to time appoint
         ------------------------------
an agent to maintain the central securities register or registers,  and an agent
or agents to maintain a branch securities  register or registers.  Such a person
may be designated as transfer agent or registrar  according to his functions and
one person may be appointed both registrar and transfer agent.  The Board may at
any time terminate any such appointment.

                                     PART 7
                      INFORMATION AVAILABLE TO SHAREHOLDERS

7.01     Available  Information:  Except as provided by the Act, no  Shareholder
         ----------------------
shall be entitled to obtain information respecting any details or conduct of the
Corporation's business which in the opinion of the Directors would not be in the
interest of the Corporation to communicate to the public.

7.02     Inspection of Information: The Directors may from time to time, subject
         -------------------------
to those rights conferred by the Act, determine whether, to what extent, at what
time and place and under what  conditions or regulations  the documents,  books,
registers and accounting records of the Corporation or any of them shall be open
to the inspection of  Shareholders,  and no Shareholder  shall have any right to
inspect any document,  book,  register or accounting  record of the  Corporation
except as conferred by statute or  authorized by the Board or by a resolution of
the Shareholders.


                                     PART 8
          INDEMNIFICATION OF DIRECTORS AND OFFICERS OF THE CORPORATION

8.01     In all  circumstances  permitted  by the  Act,  the  Corporation  shall
indemnify a Director or officer of the Corporation, a former Director or officer
of the Corporation,  or a person who acts or acted at the Corporation's  request
as a director or officer of a body corporate of which the  Corporation is or was
a shareholder or a creditor, and his heirs and legal  representatives,  from and
against:

(a) all costs, charges and expenses,  including an amount to settle an action or
    satisfy a  judgement  reasonably  incurred  by him in  respect of any civil,
    criminal or administrative  action or proceeding to which he is made a party
    by reason of being or having been a 

<PAGE>
                                       16

    Director or officer of the Corporation or such body corporate; and

(b) all other costs, charges and expenses reasonably incurred in connection with
    the defence of any civil, criminal or administrative action or proceeding to
    which he is made a party by  reason of being or having  been a  Director  or
    officer of the Corporation or such body corporate.

<PAGE>

                                   SCHEDULE B

THE  STATUTORY  PROVISIONS  CONFERRING  THE RIGHT OF DISSENT AND  APPRAISAL  ARE
TECHNICAL AND COMPLEX.  ANY HOLDER OF SHARES WHO WISHES TO EXERCISE THE RIGHT OF
DISSENT AND  APPRAISAL (A  "DISSENTING  SHAREHOLDER")  SHOULD SEEK ITS OWN LEGAL
ADVICE,  AS FAILURE  TO COMPLY  STRICTLY  WITH THE  PROVISIONS  OF THE  BUSINESS
CORPORATION ACT (ALBERTA) (THE "ACT") MAY PREJUDICE THE RIGHT OF DISSENT.

A  Dissenting  Shareholder  may only  claim  under  Section  184 of the Act with
respect to all of the shares of a class held by the Dissenting Shareholder or on
behalf of any one beneficial  owner and registered in the name of the Dissenting
Shareholder. The filing of a notice of dissent does not deprive a shareholder of
the right to vote on the  special  resolution  and a vote  against  the  special
resolution does not constitute notice of dissent.

In order to exercise his or her right of dissent, a Dissenting  Shareholder must
send to the  Corporation  a written  objection to the special  resolution  at or
before  the Annual  and  Special  General  Meeting  of  Shareholders  to be held
December 4, 1998 (the "Meeting").  After the adoption of the special  resolution
at the  Meeting,  an  application  may be made to the Court of Queen's  Bench of
Alberta (the "Court") by originating notice made either by the Corporation or by
the  Dissenting  Shareholder,   provided  the  Dissenting  Shareholder  sent  an
objection to the Corporation at or before the Meeting,  to fix the fair value of
the shares of the  Dissenting  Shareholder.  If such an application is made, the
Corporation  shall,  unless the Court otherwise orders,  send to each Dissenting
Shareholder a written offer to pay the amount  considered by the directors to be
the fair value of the  shares.  Unless the Court  otherwise  orders,  such offer
shall be sent to each  Dissenting  Shareholder at least ten days before the date
on which the application is returnable,  if the Corporation is the applicant, or
within ten days after the  Corporation is served with a copy of the  originating
notice, if the Dissenting  Shareholder is the applicant.  Every such offer shall
be made on the same terms and contain or be accompanied  by a statement  showing
how the value was determined.

A Dissenting  Shareholder  may make an agreement  with the  Corporation  for the
purchase  of the  Dissenting  Shareholder's  shares by the  Corporation,  in the
amount of the  Corporation's  offer or  otherwise,  at any time before the Court
pronounces an order fixing the fair value of the shares.

In connection  with any  application to the Court,  the Court may give direction
for: the joining as parties of all Dissenting Shareholders whose shares have not
been  purchased by the  Corporation  and for the  representation  of  Dissenting
Shareholders  who, in the opinion of the Court,  are in need of  representation;
the  trial  of  issues  and  interlocutory  matters,   including  pleadings  and
examinations  for discovery;  the payment to the  shareholders of all or part of
the sum  offered  by the  Corporation  for the  shares;  the  deposit  of  share
certificates  with the Court or with the Corporation or its transfer agent;  the
appointment  or payment of  independent  appraisers,  and the  procedures  to be
followed  by them;  the  service  of  documents;  and the burden of proof of the
parties. A Dissenting  Shareholder is not required to give security for costs in
respect of such  application  and except in special  circumstances  shall not be
required to pay costs of the application or appraisal.  On such  application the
Court shall make an order fixing the fair value of the shares of all  Dissenting
Shareholders  who are parties to the  application,  give judgment in that amount
against the Corporation and in favour of each of

<PAGE>

those  Dissenting  Shareholders,  and fix the time in which the Corporation must
pay that amount to the Dissenting Shareholders.

Upon the earlier of: (i) the Corporation  implementing  the special  resolution;
(ii) the making of an  agreement  between  the  Corporation  and the  Dissenting
Shareholder as to the payment to be made by the  Corporation  for the Dissenting
Shareholder's  shares,  whether by the acceptance of the Corporation's  offer or
otherwise;  and (iii) the pronouncement of an order by the Court, the Dissenting
Shareholder  ceases to have any rights as a shareholder  other than the right to
be paid the fair  value of the  Dissenting  Shareholder's  shares in the  amount
agreed between the Corporation  and the Dissenting  Shareholder or in the amount
of the  judgment,  as the case may be.  Until  one of such  events  occurs,  the
Dissenting  Shareholder  may withdraw the dissent or the Corporation may rescind
the  resolution  and in either event  proceedings  under  Section 184 of the Act
shall be discontinued.

The Court may in its  discretion  allow a  reasonable  rate of  interest  on the
amount  payable  to each  Dissenting  Shareholder,  from the  date on which  the
Dissenting Shareholder ceases to have any rights as a shareholder,  as described
above, until the date of payment.

The  Corporation  shall not make a payment  to a  Dissenting  Shareholder  under
Section 184 of the Act if there are  reasonable  grounds for believing  that the
Corporation  is or would after the payment be unable to pay its  liabilities  as
they  become  due or the  realizable  value of the  Corporation's  assets  would
thereby  be less  than  the  aggregate  of its  liabilities.  In such  case  the
Corporation  shall,  within ten days after the  pronouncement of an order by the
Court or the making of an agreement  between the Dissenting  Shareholder and the
Corporation  as to the  payment  to be  made  for the  Dissenting  Shareholder's
shares,  notify each  Dissenting  Shareholder  that it is unable lawfully to pay
Dissenting  Shareholders for their shares.  Notwithstanding  that a judgment has
been given in favour of the Dissenting Shareholder, if the Corporation is unable
to lawfully pay the  Dissenting  Shareholder,  the  Dissenting  Shareholder,  by
written notice  delivered to the Corporation  within thirty days after receiving
the notice that the Corporation may not lawfully pay the Dissenting Shareholder,
may withdraw the notice of objection, in which case the Corporation is deemed to
consent to withdrawal  and the Dissenting  Shareholder  is reinstated  with full
rights as a  shareholder,  failing which the  Dissenting  Shareholder  retains a
status  as a  claimant  against  the  Corporation,  to be  paid  as  soon as the
Corporation is lawfully able to do so or, in a liquidation,  to rank subordinate
to  the  rights  of  creditors  of  the  Corporation  but  in  priority  to  its
shareholders.

     (b)  if the  corporation  did not send  notice  to the  shareholder  of the
          purpose of the meeting or of his right to dissent, within a reasonable
          time after he learns that the  resolution was adopted and of his right
          to dissent.

(6)  An  application  may be made to the Court by  originating  notice after the
     adoption of a resolution  referred to in subsection  (1) or (2),
     (a)  by the corporation, or
     (b)  by a shareholder if he has sent an objection to the corporation  under

     written  offer to pay him an amount  considered  by the directors to be the
     fair value of the shares.

(8)  Unless the Court otherwise  orders,  an offer referred to in subsection (7)
     shall be sent to each dissenting shareholder

     (a)  at  least  10  days  before  the  date on  which  the  application  is
          returnable, if the corporation is the applicant, or

          originating notice, if a shareholder is the applicant.

     (b)  contain or be  accompanied  by a statement  showing how the fair value
          was determined.

(10) A dissenting shareholder may make an agreement with the corporation for the
     purchase  of  his  shares  by  the  corporation,   in  the  amount  of  the
     corporation's  offer under subsection (7) or otherwise,  at any time before
     the Court pronounces an order fixing the fair value of the shares.

(11) A dissenting shareholder

     (a)  is  not  required  to  give  security  for  costs  in  respect  of  an
          application under subsection (6), and
     (b)  except in special circumstances shall not be required to pay the costs
          of the application or appraisal.

(12) In connection with an application  under subsection (6), the Court may give
     directions  for
     (a)  joining as parties all dissenting  shareholders  whose shares have not
          been  purchased  by the  corporation  and  for the  representation  of
          dissenting  shareholders who, in the opinion of the Court, are in need
          of representation,

          made by the corporation  for his shares,  whether by the acceptance of
          the corporation's offer under subsection (7) or otherwise, or
     (c)  the pronouncement of an order under subsection (13),

<PAGE>

          whichever first occurs, the shareholder ceases to have any rights as a
          shareholder  other  than the  right  to be paid the fair  value of his
          shares  in the  amount  agreed  to  between  the  corporation  and the
          shareholder or in the amount of the judgment, as the case may be.

(15) Subsection  (14)(a)  does  not  apply  to  a  shareholder  referred  to  in
     subsection (5)(b).

(16) Until one of the  events  mentioned  in  subsection  (14)  occurs,

     (a)  the shareholder may withdraw his dissent, or

     (b)  the  corporation  may  rescind  the  resolution,
     and in either event proceedings under this section shall be discontinued.

(17) The Court may in its discretion  allow a reasonable rate of interest on the
     amount payable to each dissenting  shareholder,  from the date on which the
     shareholder  ceases  to have any  rights  as a  shareholder  by  reason  of
     subsection (14) until the date of payment.

(18) If subsection (20) applies, the corporation shall, within 10 days after
     (a)  the pronouncement of an order under subsection (13), or
     (b)  the making of an agreement between the shareholder and the corporation
          as to the payment to be made for his shares,
     notify  each  dissenting  shareholder  that it is  unable  lawfully  to pay
     dissenting shareholders for their shares.

(19) Notwithstanding  that a judgment  has been given in favour of a  dissenting
     shareholder  under  subsection  (13)(b),  if subsection  (20) applies,  the
     dissenting  shareholder,  by written  notice  delivered to the  corporation
     within 30 days  after  receiving  the notice  under  subsection  (18),  may
     withdraw his notice of objection,  in which case the  corporation is deemed
     to consent to the withdrawal and the  shareholder is reinstated to his full
     rights as a  shareholder,  failing  which he retains a status as a claimant
     against the corporation,  to be paid as soon as the corporation is lawfully

                                     AWARDS

         6.1 Types of Awards.  The types of Awards that may be granted under the
             ---------------
Plan are:

         (a) Options governed by Article 7 of the Plan;

In the discretion of the Board,  any Award may be granted alone, in addition to,
or in tandem with other Awards under the Plan.

         6.2  General.  Subject to the  limitations  of the Plan,  the Board may
              -------
cause Corporation to grant Awards to such  Participants,  at such times, of such

prices, or base prices, and subject to such terms, conditions,  limitations, and
restrictions as the Board, in its discretion,  deems appropriate;  provided that
all Awards  granted  under the Plan are subject to  approval  by any  regulatory

<PAGE>

may receive  more than one Award and more than one type of Award under the Plan,
subject to approval,  to the extent required, by any regulatory authority having
jurisdiction over Awards granted under the Plan.

         6.3 Nonuniform  Determinations.  The Board's  determinations  under the
             --------------------------
Plan or under one or more Award Agreements,  including,  without limitation, the
selection of Participants to receive Awards,  the type, form, amount, and timing
of  Awards,   the  terms  of  specific  Award  Agreements,   and  elections  and
determinations made by the Board with respect to exercise or payments of Awards,
need not be uniform and may be made by the Board selectively among  Participants
and  Awards,  whether or not  Participants  are  similarly  situated.  

         6.4 Award  Agreements.  Each Award will be evidenced by a written Award
             -----------------
Agreement between Corporation and the Participant. Award Agreements, or the form
thereof, must be approved by the Board and may, subject to the provisions of the
Plan, contain any provision approved by the Board,  subject to approval,  to the
extent required,  by any regulatory  authority having  jurisdiction  over Awards
granted under the Plan. 

         6.5 Provisions  Governing All Awards. All Awards will be subject to the
             --------------------------------
following  provisions:  

         (a)  Alternative  Awards.  If any Awards are  designated in their Award
              -------------------
    Agreements as alternative to each other,  the exercise of all or part of one
    Award   automatically   will  cause  an   immediate   equal  (or  pro  rata)
    corresponding termination of the other alternative Award or Awards.

         (b) Rights as  Shareholders.  No Participant  will have any rights of a
             -----------------------
    shareholder with respect to Shares subject to an Award until such Shares are
    issued in the name of the Participant.

         (c)  Employment  Rights.  Neither  the  adoption  of the  Plan  nor the
              ------------------
    granting  of any Award  will  confer on any  person  the right to  continued
    employment  with  Corporation  or any Subsidiary or the right to remain as a
    director of or a consultant to  Corporation or any  Subsidiary,  as the case
    may be, and will not interfere in any way with the right of Corporation or a
    Subsidiary to terminate such person's employment or to remove such person as
    a  Consultant  or as a director at any time for any reason or for no reason,
    with or without cause.

         (d) Termination Of Employment.  The terms and conditions under which an
             -------------------------
    Award may be exercised,  if at all,  after a  Participant's  termination  of
    employment  or service  as a  Nonemployee  Director  or  Consultant  will be
    determined by the Board and  specified in the  applicable  Award  Agreement,
    subject to approval,  to the extent  required,  by any regulatory  authority
    having jurisdiction over Awards granted under the Plan.

         (e) Change in Control. The Board, in its discretion, may provide in any
             -----------------
    Award  Agreement that in the event of a change in control of Corporation (as
    the Board may define  such term in the Award  Agreement),  as of the date of
    such change in control:

                                     - 7 -
<PAGE>

              (i) All, or a specified portion of, Awards requiring exercise will
         become fully and  immediately  exercisable,  notwithstanding  any other
         limitations on exercise;

              (ii)  All,  or  a  specified   portion  of,   Awards   subject  to
         Restrictions  will become fully  Vested;  and 

              (iii)  All,  or  a  specified   portion  of,  Awards   subject  to
         Performance Goals will be deemed to have been fully earned.  

    The Board,  in its discretion,  may include change in control  provisions in
    some Award  Agreements and not in others,  may include  different  change in
    control provisions in different Award Agreements,  and may include change in
    control provisions for some Awards or some Participants and not for others.

         (f)  Reporting  Persons.  Notwithstanding  anything  in the Plan to the
              ------------------
    contrary, the Board, in its sole discretion, may bifurcate the Plan so as to
    restrict,  limit,  or  condition  the use of any  provision  of the  Plan to
    Participants who are Reporting  Persons without so restricting,  limiting or
    conditioning the Plan with respect to other Participants.

         (g)  Service  Periods.  At the time of granting  Awards,  the Board may
              ----------------
    specify,  by resolution or in the Award Agreement,  the period or periods of
    service  performed or to be performed by the  Participant in connection with
    the grant of the Award.  

         (h)  Nontransferability.  Each  Award  shall  not  be  transferable  or
              ------------------
    assignable  otherwise  than by will or the laws of descent and  distribution
    and shall be  exercisable  (if exercise is required)  during the lifetime of
    the  Participant,  only by the  Participant or, in the event the Participant
    becomes  legally  incompetent,   by  the  Participant's  guardian  or  legal
    representative.

                                    OPTIONS

         7.1 Types of Options. Options granted under the Plan may be in the form
             ----------------
of Incentive Stock Options or Nonqualified Options. The grant of each Option and
the Award Agreement  governing each Option will identify the Option as an ISO or
an NQO.  In the event the Code is amended to provide  for  tax-favored  forms of
stock options other than or in addition to Incentive  Stock  Options,  the Board
may grant  Options  under the Plan  meeting  the  requirements  of such forms of
options.

         7.2 General.  Options will be subject to the terms and  conditions  set
             -------
forth  in  Article  6 of the  Plan  and  this  Article  7 and may  contain  such
additional terms and conditions, not inconsistent with the express provisions of
the Plan, as the Board deems  desirable,  subject to approval by any  regulatory
authority  having  jurisdiction  over Awards  granted under the Plan. 

         7.3 Option  Price.  Each Award  Agreement  for  Options  will state the
             -------------
option  exercise price per Share of Common Stock  purchasable  under the Option,
which will not be less than:

         (a) 75 percent of the Fair Market Value of a Share on the date of grant
    for all Nonqualified Options; or

         (b) 100  percent  of the  Fair  Market  Value of a Share on the date of
    grant for all Incentive  Stock  Options;  

provided  that at no time  shall the option  exercise  price of an Option at the
date of grant be  greater  or less than that  permitted  under the  regulations,
guidelines or policies of any  regulatory  authority  having  jurisdiction  over
Awards granted under the Plan.

         7.4 Option Term.  The Award  Agreement for each Option will specify the
             -----------
term  during  which the Option may be  exercised,  as  determined  by the Board,
subject to approval by any regulatory  authority having jurisdiction over Awards
granted under the Plan.

         7.5 Time of Exercise. The Award Agreement for each Option will specify,
             ----------------
as  determined  by the Board:  

         (a) The time or times  when the  Option  will  become  exercisable  and
    whether the Option will become  exercisable in full or in graduated  amounts
    over a period specified in the Award Agreement;

         (b) Such  other  terms,  conditions,  and  restrictions  as to when the
    Option may be exercised as are determined by the Board;  and 

         (c) The extent,  if any,  to which the Option  will remain  exercisable
    after the  Participant  ceases to be an employee,  Consultant or Nonemployee
    Director of Corporation or a Subsidiary;  

in  each  case,   subject  to  approval  by  any  regulatory   authority  having
jurisdiction  over Awards  granted  under the Plan.  An Award  Agreement  for an
Option may, in the discretion of the Board, provide whether, and to what extent,
the Option will become immediately and fully exercisable (i) in the event of the
death, Disability, or Retirement of the Participant, or (ii) upon the occurrence
of a change in control of Corporation.

         7.6  Method of  Exercise.  The Award  Agreement  for each  Option  will
              -------------------
specify the method or methods of payment  acceptable upon exercise of an Option.
An Award  Agreement may provide that the option price is payable in full in cash
or, at the  discretion  of the Board,  by  delivery  (in a form  approved by the
Board) of an  irrevocable  direction to a securities  broker  acceptable  to the
Board (i) to sell  Shares  subject to the Option and to deliver all or a part of
the sales  proceeds  to  Corporation  in  payment of all or a part of the option
price and withholding  taxes due, or (ii) to pledge Shares subject to the Option
to the broker as  security  for a loan and to deliver  all or a part of the loan
proceeds  to  Corporation  in payment  of all or a part of the option  price and
withholding taxes due.

         7.7 Special Rules for Incentive Stock Options. In the case of an Option
             -----------------------------------------
designated as an Incentive  Stock Option,  the terms of the Option and the Award
Agreement shall be in conformance with the statutory and regulatory requirements
specified  in  Section  422 of the  Code,  as in  effect on the date such ISO is
granted.  ISOs may not be granted under the Plan after

Code is removed or extended.

                           STOCK APPRECIATION RIGHTS

         8.1 General. Stock Appreciation Rights will be subject to the terms and
             -------
conditions set forth in Article 6 of the Plan and this Article 8 and may contain
such additional terms and conditions, not inconsistent with the express terms of
the Plan,  as the Board  deems  desirable,  subject to  approval,  to the extent
required,  by any regulatory  authority having  jurisdiction over Awards granted
under the Plan.

         8.2 Nature of Stock Appreciation  Right. A Stock Appreciation Right (or
             -----------------------------------
SAR) is an Award  entitling  a  Participant  to receive  an amount  equal to the
excess  (or if the  Board  determines  at the time of grant,  a  portion  of the
excess) of the Fair  Market  Value of a Share on the date of exercise of the SAR
over  the  base  price,  as  described  below,  on the date of grant of the SAR,
multiplied  by the number of Shares with respect to which the SAR is  exercised.
The base price will be  designated  by the Board in the Award  Agreement for the
SAR and may be the Fair Market  Value of a Share on the grant date of the SAR or
such other higher or lower price as the Board determines.  

         8.3  Exercise.  A  Stock  Appreciation  Right  may  be  exercised  by a
              --------
Participant in accordance  with procedures  established by the Board.  The Board
may also  provide  that a SAR  will be  automatically  exercised  on one or more
specified dates or upon the  satisfaction  of one or more specified  conditions.

         8.4 Form of Payment.  Payment  upon  exercise  of a Stock  Appreciation
             ---------------
Right may be made in cash, in installments,  in Shares,  or in any other form or
combination of such methods as the Board shall  determine.  


                                   ARTICLE 9
                                RESTRICTED UNITS

         9.1 Nature of Restricted  Units. A Restricted Unit is an Award of stock
             ---------------------------
units  (with each unit  having a value  equivalent  to one  Share)  granted to a
Participant subject to such terms and conditions as the Board deems appropriate,
and may include a requirement that the Participant forfeit such Restricted Units
upon  termination  of  Participant's  employment  (or service as a Consultant or
Nonemployee Director) for specified reasons within a specified period of time or
upon other  conditions,  as set forth in the Award Agreement for such Restricted
Units.

         9.2  General.  Restricted  Units  will  be  subject  to the  terms  and
              -------
conditions  of  Article 6 of the Plan and this  Article 9 and may  contain  such
additional terms and conditions, not inconsistent with the express provisions of
the Plan,  as the Board  deems  desirable,  subject to  approval,  to the extent
required,  by any regulatory  authority having  jurisdiction over Awards granted
under the Plan. 

         9.3 Restriction Period. Restricted Units will provide that such Awards,
             ------------------
and the Shares subject to such Awards,  may not be transferred,  and may provide
that, in order for a 

                                     - 10 -
<PAGE>

Participant  to  Vest  in  such  Awards,  the  Participant  must  remain  in the
employment (or remain as a Consultant or Nonemployee Director) of Corporation or
its  Subsidiaries,  subject  to  relief  for  reasons  specified  in  the  Award
Agreement,  for a period commencing on the date of grant of the Award and ending
on such later date or dates as the Board may  designate at the time of the Award
(the "Restriction Period"). During the Restriction Period, a Participant may not
sell,  assign,  transfer,  pledge,  encumber,  or  otherwise  dispose  of Shares
underlying Restricted Units. The Board, in its sole discretion,  may provide for
the lapse of restrictions in installments  during the Restriction  Period.  Upon
expiration of the applicable Restriction Period (or lapse of Restrictions during
the  Restriction  Period  where  the  Restrictions  lapse in  installments)  the
Participant  will be entitled to settlement of the  Restricted  Units or portion
thereof,  as the case may be. Although  Restricted Units usually will Vest based
on continued  employment  (or continued  service as a Consultant or  Nonemployee
Director) and Performance  Awards under Article 10 of the Plan will usually Vest
based on attainment of Performance  Goals,  the Board,  in its  discretion,  may
condition Vesting of Restricted Units on attainment of Performance Goals as well
as continued  employment  (or continued  service as a Consultant or  Nonemployee
Director).  In such case, the Restriction  Period for such Restricted Units will
include  the  period  prior  to  satisfaction  of  the  Performance  Goals.  

         9.4  Forfeiture.  If  a  Participant  ceases  to  be  an  employee  (or
              ----------
Consultant or Nonemployee  Director) of  Corporation or a Subsidiary  during the
Restriction  Period for any reason other than reasons  which may be specified in
an  Award  Agreement  (such as  death,  Disability,  or  Retirement)  the  Award
Agreement may require that all non-Vested Restricted Units previously granted to
the Participant be forfeited and returned to Corporation.

         9.5 Settlement of Vested Restricted Units. Upon Vesting of an Award (or
             -------------------------------------
portion thereof) of Restricted  Units, a Participant will be entitled to receive
payment for  Restricted  Units in an amount equal to the  aggregate  Fair Market
Value of the number of Shares covered by such Restricted Units at the expiration
of the applicable Restriction Period. Payment in settlement of a Restricted Unit
will be made as soon as  practicable  following the conclusion of the applicable
Restriction  Period in cash, in  installments,  in Shares equal to the number of
Restricted  Units,  or in any other form or  combination  of such methods as the
Board, in its sole discretion, determines.

                               PERFORMANCE AWARDS

         10.1  General.  Performance  Awards  will be  subject  to the terms and
               -------
conditions  set  forth in  Article  6 of the Plan  and this  Article  10 and may
contain  such other  terms and  conditions  not  inconsistent  with the  express
provisions of the Plan, as the Board deems  desirable,  subject to approval,  to

granted under the Plan.

         10.2 Nature of Performance  Awards. A Performance  Award is an Award of
              -----------------------------
stock units (with each unit having a value equivalent to one Share) granted to a
Participant subject to such terms and conditions as the Board deems appropriate,
including, without limitation, the requirement that the Participant forfeit such
Performance Award or a portion of

                                     - 11 -
<PAGE>

such  Award  in the  event  specified  Performance  Goals  are not met  within a
designated  Performance  Cycle.  

         10.3 Performance  Cycles.  For each  Performance  Award, the Board will
              -------------------
designate a performance  period (the "Performance  Cycle") with a duration to be
determined by the Board in its  discretion  within which  specified  Performance
Goals are to be attained.  There may be several  Performance Cycles in existence
at any one time and the duration of Performance  Cycles for specific  Awards may
differ from each other.

         10.4  Performance  Goals.  For each  Performance  Award, the Board will
               ------------------
establish Performance Goals on the basis of such criteria and to accomplish such
objectives as the Board may from time to time select.  Performance  Goals may be
based on performance  criteria for  Corporation,  a Subsidiary,  or an operating
group  or  division,  or  based  on  a  Participant's   individual  performance.
Performance  Goals may include  objective and  subjective  criteria.  During any
Performance  Cycle,  the  Board  may  adjust  the  Performance  Goals  for  such
Performance   Cycle  as  it  deems   equitable  in  recognition  of  unusual  or
nonrecurring  events  affecting  Corporation,  changes in applicable tax laws or
accounting principles, or such other factors as the Board may determine.

         10.5  Determination of Vested Awards.  As soon as practicable after the
               ------------------------------
end of a  Performance  Cycle,  the  Board  will  determine  the  extent to which
Performance  Awards have been earned on the basis of  performance in relation to
the established Performance Goals.

         10.6  Timing  and Form of  Payment.  Settlement  of earned  Performance
               ----------------------------
Awards  will be made  to the  Participant  as  soon  as  practicable  after  the
expiration of the Performance Cycle and the Board's  determination under Section
10.5,  in  the  form  of  cash,  installments,  or  Shares,  or in any  form  or
combination of such methods as the Board determines.

                    OTHER STOCK-BASED AND COMBINATION AWARDS

         11.1 Other Stock-Based  Awards.  The Board may grant other Awards under
              -------------------------
the Plan  pursuant  to which  Shares  are or may in the future be  acquired,  or
Awards  denominated in or measured by Share equivalent  units,  including Awards
valued  using  measures  other  than the  market  value of  Shares.  Such  Other
Stock-Based  Awards may be granted  either  alone,  in addition to, or in tandem
with, any other type of Award granted under the Plan.

         11.2 Combination Awards. The Board may also grant Awards under the Plan
              ------------------
in tandem or  combination  with other  Awards or in  exchange  of Awards,  or in
tandem or combination  with, or as  alternatives  to, grants or rights under any
other employee plan of Corporation,  including the plan of any acquired  entity.
No action  authorized  by this  section  will reduce the amount of any  existing
benefits or change the terms and conditions  thereof  without the  Participant's
consent.

         The Board may  permit a  Participant  to elect to defer  receipt of the
payment of cash or the  delivery of Shares that would  otherwise  be due to such
Participant  by virtue of the  exercise,  earn-out,  or Vesting of an Award made
under the Plan.  If any such  election is  permitted,  the Board will  establish
rules and procedures for such payment deferrals,  including, but not limited to,

cash.

         13.1 Plan Does Not Restrict Corporation.  The existence of the Plan and
              ----------------------------------

         13.2  Adjustments  by  the  Board.  In  the  event  of  any  change  in
               ---------------------------
capitalization  affecting the Shares of  Corporation,  such as a stock dividend,
stock split, recapitalization,  merger, consolidation,  split-up, combination or
exchange  of  shares  or  other  form of  reorganization,  or any  other  change
affecting the Shares,  such proportionate  adjustments as the Board, in its sole
discretion,  deems appropriate to reflect such change, will be made with respect
to the  aggregate  number of Shares for which  Awards in respect  thereof may be
granted  under  the Plan,  the  maximum  number  of Shares  which may be sold or
awarded to any  Participant,  the number of Shares  covered by each  outstanding
Award, and the price per Share in respect of outstanding  Awards.  The Board may
also make such  adjustments  in the  number of Shares  covered  by, and price or
other  value of any  outstanding  Awards  in the  event of a  spin-off  or other
distribution  (other than  normal  cash  dividends),  of  Corporation  assets to
shareholders.

          Without further approval of Corporation's shareholders,  the Board may
at any time  terminate  the  Plan,  or may  amend  it from  time to time in such
respects  as the  Board  may deem  advisable;  provided  that the Board may not,
without approval of the  shareholders,  make any amendment that would materially
increase  the  aggregate  number  of Shares  that may be  issued  under the Plan
(except  for  adjustments  pursuant  to Article 13 of the  Plan);  and  provided
further  that any  amendment  of the Plan shall be subject to  approval,  to the
extent required, by any regulatory authority having jurisdiction over the Plan.

                                  MISCELLANEOUS

         15.1 Tax Withholding.

         15.1.1  General.  Corporation  will have the  right to deduct  from any
                 -------
settlement  of any Award under the Plan,  including  the  delivery or vesting of
Shares,  any  taxes of any kind  required  by the laws of any  Canadian  or U.S.
jurisdiction  to be withheld with respect to such payments or to take such other
action  as may be  necessary  in the  opinion  of  Corporation  to  satisfy  all
obligations  for the  payment of such  taxes.  The  recipient  of any payment or
distribution under the Plan may be required to make arrangements satisfactory to
Corporation  for the  satisfaction  of any  such  withholding  tax  obligations,
whether or not such  recipient is an employee of  Corporation or a Subsidiary on
the date of such  settlement.  Corporation will not be required to make any such
payment or distribution under the Plan until such obligations are satisfied.

         15.1.2 Stock Withholding. The Board, in its sole discretion, may permit
                -----------------
a  Participant  to  satisfy  all or a part of the  withholding  tax  obligations
incident to the settlement of an Award  involving  payment or delivery of Shares
to the Participant by having  Corporation  withhold a portion of the Shares that
would otherwise be issuable to the Participant. Such Shares will be valued based
on their Fair  Market  Value on the date the tax  withholding  is required to be
made. 

         15.2 Unfunded Plan. The Plan will be unfunded and Corporation shall not
              -------------
be  required to  segregate  any assets  that may at any time be  represented  by
Awards under the Plan.  Any liability of  Corporation to any person with respect
to any  Award  under  the  Plan  will  be  based  solely  upon  any  contractual
obligations  that may be effected  pursuant to the Plan.  No such  obligation of
Corporation shall be deemed to be secured by any pledge of, or other encumbrance
on, any property of Corporation.

         15.3  Payments  to  Trust.  The  Board  is  authorized  to  cause to be
               -------------------
established a trust agreement or several trust  agreements  whereunder the Board
may make payments of amounts due or to become due to  Participants  in the Plan.
However,  the Board has no  obligation to establish  such a trust or fund.  

         15.4  Annulment  of Awards.  Any Award  Agreement  may provide that the
               --------------------
grant  of an  Award  payable  in  cash  is  provisional  until  cash  is paid in
settlement  of such  Award or that the  grant of an Award  payable  in Shares is
provisional  until the Participant  becomes entitled to the stock certificate in
settlement  of  such  Award.  In the  event  the  employment  (or  service  as a
Consultant or Nonemployee Director) of a Participant is terminated for cause (as
defined below), any Award that is provisional will be annulled as of the date of
such  termination for cause. For the purpose of this Section 15.4, the term "for
cause"  will  have  the  meaning  set  forth  in  the  Participant's  employment
agreement, if any, or otherwise means any discharge (or removal) for material or
flagrant  violation of the policies and  procedures of  Corporation or for other
job performance or conduct that is materially  detrimental to the best interests
of Corporation,  as determined by the Board.

         15.5 Engaging in Competition With Corporation.  Any Award Agreement may
              ----------------------------------------
provide that, if a  Participant  terminates  employment  with  Corporation  or a
Subsidiary  for any reason  whatsoever,  and within 18 months  after the date of
such termination accepts employment with any competitor of (or otherwise engages
in competition with) Corporation, the Board, in its sole discretion, may require
such  Participant to return to Corporation  the economic value of any Award that
is realized or obtained (measured at the date of exercise,  Vesting, or payment)
by such  Participant at any time during the period beginning on the date that is
six months prior to the date of such  Participant's  termination  of  employment
with  Corporation.  

         15.6 Other Corporation Benefit and Compensation Programs.  Payments and
              ---------------------------------------------------
other  benefits  received by a  Participant  under an Award made pursuant to the
Plan  will  not  be  deemed  a  part  of  a  Participant's  regular,   recurring
compensation  for purposes of the termination  indemnity or severance pay law of
any state or  country  and will not be  included  in, or have any effect on, the
determination  of  benefits  under any other  employee  benefit  plan or similar
arrangement provided by Corporation or a Subsidiary unless expressly so provided
by such  other  plan or  arrangements,  or  except  where  the  Board  expressly
determines that an Award or portion of an Award should be included to accurately
reflect  competitive  compensation  practices or to recognize  that an Award has
been made in lieu of a portion of cash  compensation.  Awards under the Plan may
be made in combination  with or in tandem with, or as  alternatives  to, grants,
awards,   or  payments  under  any  other   Corporation  or  Subsidiary   plans,
arrangements,  or  programs.  The  Plan  notwithstanding,   Corporation  or  any
Subsidiary   may  adopt  such  other   compensation   programs  and   additional
compensation  arrangements as it deems necessary to attract,  retain, and reward
employees and directors for their service with Corporation and its Subsidiaries.

         15.7  Securities Law  Restrictions.  No Shares will be issued under the
               ----------------------------
Plan unless  counsel for  Corporation is satisfied that such issuance will be in
compliance  with  the  applicable  securities  laws  of  any  Canadian  or  U.S.
jurisdiction. Certificates for Shares delivered under the Plan may be subject to
such  stop-transfer  orders and other  restrictions as the Board deems advisable
under the rules,  regulations,  and other  requirements  of the  Securities  and
Exchange Commission, the Alberta or British Columbia Securities Commissions, any
stock  exchange  upon  which the  Shares  are then  listed,  and any  applicable
securities  law.  The Board may cause a legend or  legends to be put on any such
certificates to make appropriate reference to such restrictions.  

         15.8  Governing  Law.  Except with respect to references to the Code or
               --------------
applicable  securities  laws, the Plan and all actions taken  thereunder will be
governed by and  construed in  accordance  with the laws of the State of Oregon.


                                   ARTICLE 16
                              SHAREHOLDER APPROVAL

           The adoption of the Plan, as amended and restated  effective  October
15, 1997,  and any grant of Awards under the Plan are  expressly  subject to the
approval  of the  Plan  by  the  shareholders  at the  1997  annual  meeting  of
Corporation's  shareholders.  In the event  that such  shareholder  approval  is
received, no additional stock options will be granted thereafter under the 

                                     - 15 -
<PAGE>

Stock Option Plan and such plan will immediately  terminate;  provided that such
termination will have no effect on any options previously granted thereunder.
