RECITALS

     WHEREAS, simultaneously with the execution
and delivery of this Agreement, the Company has entered into a subscription

and 291,667 warrants (the "Warrants"), each Warrant to purchase one
Common Share (collectively, the "Warrant Shares"); and

     WHEREAS, the Company has agreed to grant
to Holder certain registration rights with respect to the Shares and Warrant
Shares being issued to Holder pursuant to the Subscription Agreement upon the
terms and conditions herein set forth.

     NOW, THEREFORE, for good and valuable

"SEC"), a registration statement (the "Registration
Statement") and such other documents, including a prospectus, as may be
necessary, in order to comply with the provisions of the Securities Act of 1933,
as amended (the "Act"), so as to permit the public sale of the
Registrable Shares (defined below).  The Company will use reasonable commercial
efforts to file the Registration Statement within 45 days from the Closing Date
(as defined in the Subscription Agreement), respond to the SEC's comments (if
any) within 10 business days of receipt of said comments and use its best
efforts to cause the Registration Statement to become effective within 120 days
from the Closing Date.

2.     Registrable Shares.   
  For purposes of this Agreement, the term "Registrable Shares" shall
mean each of the Shares and Warrant Shares (whether issued or issuable) and any
securities issued or issuable with respect to the Shares or Warrant Shares by
way of stock dividend or stock split or in connection with a combination of
shares, recapitalization, merger, consolidation or other reorganization or
otherwise. Once issued, any such securities shall cease to be Registrable Shares
registerable hereunder upon the earlier of (a) the sale of such securities
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Act"), (b) the distribution thereof to the
public pursuant to Rule 144 (or any successor provision) under the Act, (c) a
transfer pursuant to which new certificates for them not bearing a legend
restricting further transfer shall have been delivered by the Company and
subsequent disposition of them shall not require registration or qualification
of them under the Act or any similar state law then in force, (d) they shall
have ceased to be outstanding, or (e) any and all legends restricting transfer
thereof may been 

removed in accordance with the provisions of Rule 144(k) (or any successor
provision) under the Act.

     3.     Covenants of
the Company With Respect to Registration.  The Company hereby covenants and
agrees as follows:

          
(a)     Following the
effective date of the Registration Statement, the Company shall, upon the
request of Holder, forthwith supply such reasonable number of copies of the
Registration Statement and prospectus meeting the requirements of the Act as
shall be reasonably requested by Holder to permit Holder to make a public
distribution of the Registrable Shares.  The obligations of the Company
hereunder with respect to the Registrable Shares are expressly conditioned on
Holder's furnishing to the Company such appropriate information concerning
Holder, the Registrable Shares and the terms of Holder's offering of such shares
as the Company may request.

          
(b)     The Company
will pay all costs, fees and expenses in connection with all Registration
Statements filed pursuant to this Agreement, including, without limitation, the
Company's legal and accounting fees, printing expenses and blue sky fees and
expenses; provided, however, that Holder shall be solely responsible for the
fees of any counsel or advisor retained by Holder in connection with such
registration and any transfer taxes or brokerage discounts, selling commissions
or selling fees applicable to the Registrable Shares sold by Holder pursuant
thereto.

          
(c)     The Company
will use reasonable efforts to qualify or register the Registrable Shares
included in a Registration Statement for offering and sale under the securities
or blue sky laws of such states as are reasonably requested by Holder, provided
that the Company shall not be obligated to execute or file any general consent
to service of process (unless the Company is already then subject to service in
such jurisdiction) or to qualify as a foreign corporation to do business under
the laws of any such jurisdiction.

          
(d)     The Company
shall use its best efforts to keep the Registration Statement effective until
the twelve month anniversary of its effective date or, if earlier, until the
distribution contemplated in the Registration Statement has been completed.

          
(e)     The Company
shall notify Holder in writing at any time when a prospectus relating to the
Registration Statement is required to be delivered under the Securities Act, of
the occurrence of any event as a result of which the prospectus included in the
Registration Statement (including any document to be incorporated by reference
therein) contains any untrue statement of a material fact or omits any fact
necessary to make the statements therein not misleading and, to the extent it is
obligated to continue to use its best efforts to keep the Registration Statement
effective pursuant to Section 3(d), at the request of the Holder, the Company
shall prepare a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable Shares, such
prospectus will not contain an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading and promptly make available to the Holder any
such supplement or amendment.

-2-

          
(f)     The Company
shall notify Holder promptly and in writing, (i) when the Registration
Statement, the prospectus or any prospectus supplement or post-effective
amendment has been filed, and, with respect to the Registration Statement or any
post-effective amendment, when the same has become effective, (ii) of the
issuance by the SEC of any stop order suspending the effectiveness of a
Registration Statement or of any order preventing or suspending the use of any
preliminary prospectus or the initiation of any proceedings for that purpose
and, to the extent it is obligated to continue to use its best efforts to keep
the Registration Statement effective pursuant to Section 3(d), the Company shall
promptly use its reasonable best efforts to prevent the issuance of any stop
order or to obtain its withdrawal if such stop order should be issued and (iii)
of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of a Registration Statement
or any of the Registrable Shares for offer or sale in any jurisdiction, or the
initiation or threatening of any proceeding for such purpose.

          
(g)     Nothing
contained in this Agreement shall require the Company to undergo an audit, other
than in the ordinary course of business.

          
(h)     In the event
that the Company grants to any purchasers of securities of the Company in any
private placement completed within twelve months from the date of this Agreement
(the "Other Securities") a penalty, liquidation reimbursement,
liquidated damages or similar payment in the event that the Company does not
file a registration statement covering the Other Securities by a specified date
or a registration statement covering the Other Securities is not declared
effective by a specified date, if the Registration Statement has not been filed
and/or declared effective by the SEC by the respective date(s) on which the
payment to the holders of the Other Securities is due, the Company will make a
payment to the Holder at the same rate (i.e., pro rata based on the aggregate
purchase price of the Registrable Shares and the aggregate purchase price of the
Other Securities) as paid to the holders of Other Securities

     4.     Covenant of
Holder.

          
(a)     Holder, upon
receipt of notice from the Company that an event has occurred which requires a
post-effective amendment to any registration statement covering Registrable
Shares or a supplement to the prospectus included therein or that a stop order
has been issued by the SEC, shall promptly discontinue the sale of the
Registrable Shares until Holder receives a copy of a supplemented or amended
prospectus from the Company, which the Company shall provide as soon as
practicable after such notice.

          
(b)     Holder agrees
to fully cooperate with the Company and to furnish to the Company such
information regarding Holder as the Company may from time to time deem
reasonably necessary in connection with the preparation and filing of any
registration statement covering the Registrable Shares. 

          
(c)     The Holder,
upon receipt of notice from the Company that an event of the kind described in
Sections 3(e) or (f) (ii) or (iii) has occurred which requires a post-effective
amendment to the Registration Statement or a supplement to the prospectus
included therein, shall promptly discontinue the sale of Registrable Securities
until the Holder receives a copy of a 

-3-

supplemented or amended prospectus from the Company, which the Company shall
provide immediately after such notice.

          
(d)     It shall be a
condition precedent to the obligations of the Company under this Agreement that
the Holder shall furnish to the Company such information regarding itself, the
Registrable Shares and other securities of the Company held by it and the
intended method of liabilities of the Registrable Shares as still be reasonably
requested to effect the filing and effectiveness of the Registration Statement
and registration of such Registrable Shares.

     5.    
 Indemnification.
          
(a)     The Company
agrees to indemnify and hold harmless Holder, the affiliates of Holder, the
directors, partners, officers, employees and agents of Holder and each person
who controls Holder within the meaning of either the Act or the Securities
Exchange Act of 1934 (the "Exchange Act") against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them
may become subject under the Act, the Exchange Act or other Federal or state
statutory law or regulation, at common law or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in a Registration Statement as originally filed or in any
amendment thereof, or in any prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or arise out of any
violation or alleged violation by the Company of the Securities Act, the
Exchange Act, any state securities laws or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any state securities laws, and
agrees to reimburse each such indemnified party, as incurred, for any reasonable
legal or other expenses or losses incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that (i) the Company will not be liable in any case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished (or failed to furnish in the case of an omission or
alleged omission) to the Company by or on behalf of Holder specifically for
inclusion therein, (ii) the Company will not be liable to any indemnified party
under this indemnity agreement with respect to any Registration Statement or
prospectus to the extent that any such loss, claim, damage or liability of such
indemnified party results from the use of the prospectus during a period when
the use of the prospectus has been suspended, provided that Holder received
prior written notice of such suspension; and (iii) the Company shall not be
liable to any indemnified party with respect to any preliminary prospectus to
the extent that any such loss, claim, damage or liability of such indemnified
party results from the fact that such indemnified party sold Registrable Shares
to a person as to whom there was not sent or given, at or prior to the written
confirmation of such sale, a copy of the prospectus or of the prospectus as then
amended or supplemented in any case where such delivery is required by the Act,
if the loss, claim, damage or liability of such indemnified party results from
an untrue statement or omission of a material fact contained in the preliminary
prospectus which was corrected in the prospectus or in the prospectus as then
amended or supplemented.

-4-

          
(b)     Holder shall
indemnify and hold harmless the Company, each of its directors, each of its
officers who signs the Registration Statement and each person who controls the
Company within the meaning of either the Act or the Exchange Act against any and
all losses, claims, damages or liabilities, joint or several, to which they or
any of them may become subject under the Act, the Exchange Act or other Federal
or state statutory law or regulation, at common law or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof) (i)
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact contained in a Registration Statement as originally filed or
in any amendment thereof, or in any prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only insofar as
any such statement, omission, alleged statement or alleged omission was made in
reliance upon and in conformity with information furnished to the Company by the
Holder, (ii) results from the use of the prospectus during a period when the use
of the prospectus has been suspended, provided that Holder received prior
written notice of such suspension, or (iii) results from the fact that the
Holder sold Registrable Shares to a person as to whom there was not sent or
given, at or prior to the written confirmation of such sale, a copy of the
prospectus or of the prospectus as then amended or supplemented in any case
where such delivery is required by the Act, if the loss, claim, damage or
liability results from an untrue statement or omission of a material fact
contained in the preliminary prospectus which was corrected in the prospectus or
in the prospectus as then amended or supplemented, and agrees to reimburse each
such indemnified party, as incurred, for any reasonable legal or other expenses
or losses incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action.

          
(c)     Promptly after
receipt by an indemnified party under this Section 5 of notice of the
commencement of any action or investigation, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 5, notify the indemnifying party in writing of the commencement thereof;
but the failure so to promptly notify the indemnifying party will not relieve
the indemnifying party from liability under Section 5(a) or 5(b) hereof unless
it is prejudiced thereby.  The indemnifying party shall be entitled to appoint
counsel of the indemnifying party's choice at the indemnifying party's expense
to represent the indemnified party in any action for which indemnification is
sought (in which case the indemnifying party shall not thereafter be responsible
for the fees and expenses of any separate counsel retained by the indemnified
party or parties except as set forth below); provided, however, that such
counsel shall be reasonably satisfactory to the indemnified party.
Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified parties shall have
the right to employ one separate counsel and the indemnifying party shall bear
the reasonable fees, costs and expenses of such separate counsel if (i) the use
of counsel chosen by the indemnifying party to represent the indemnified party
would present such counsel with a conflict of interest, (ii) the actual or
potential defendants in, or targets of, any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be legal defenses available to it
and/or other indemnified parties which are different from or additional to those
available to the indemnifying party, (iii) the indemnifying party shall not have
employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of the institution of
such action or (iv) the indemnifying party shall 

-5-

authorize the indemnified party to employ separate counsel at the expense of
the indemnifying party.  An indemnified party shall not settle or compromise any
action for which it seeks indemnification or contribution hereunder without the
prior written consent of the indemnifying party, which consent shall not be
unreasonably withheld.  An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any pending or threatened claim,
action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or
consent includes an unconditional release of each indemnified party from all
liability arising out of such claim, action, suit or proceeding.

          
(d)     The
obligations of the Company and Holder under this Section 5 shall survive the
completion of any offering of Registrable Securities.

SOLD, PLEDGED, TRANSFERRED, DISTRIBUTED OR OTHERWISE DISPOSED OF IN ANY MANNER

OSI.

          4.2  
OSI acknowledges that representatives of OSI have received and reviewed copies
of the SEC Filings (defined below), including, in each case, the exhibits
thereto and all of the documents incorporated by reference therein; that
representatives of OSI have had the opportunity to review public information
concerning the Company, and understands such information.  

          4.3  
OSI represents that its representatives are sophisticated investors familiar
with the type of risks inherent in the acquisition of securities such as the

risks of an investment in the Shares and Warrants.  

          4.4  
OSI is able to bear the economic risk of an investment in the Shares and
Warrants, including, without limiting the generality of the foregoing, the risk

period of time.

          4.6  
OSI further acknowledges that the Shares and Warrants have not been registered
under the Act or any of the Other Securities Laws, and may not be sold,

          4.8  
OSI is a corporation duly organized, validly existing and in good standing under
the laws of California and has full corporate power and corporate authority to
own, lease and operate its properties and conduct its current business; OSI is
duly qualified to do business as a foreign corporation and in good standing in
each jurisdiction in which the ownership or leasing of its properties or the
conduct of its business requires such qualification, except where the failure to
be so qualified or be in good standing is not reasonably likely to have a
Material Adverse Effect (defined below) on OSI and no proceeding has been
instituted in any such jurisdiction revoking, limiting or curtailing, or seeking
to revoke, limit or curtail, such power and authority or qualification.

          4.9

5.     The Company's Representations, Warranties
and Covenants.

The Company hereby represents and warrants to and covenants with OSI as
follows:

          5.1  
The Company is a corporation duly organized, validly existing and in good
standing under the laws of British Columbia, Canada and has full corporate power
and corporate authority to own, lease and operate its properties and conduct its
current business; the Company is duly qualified to do business as a foreign
corporation and in good standing in each jurisdiction in which the ownership or
leasing of its properties or the conduct of its business requires such
qualification, except where the failure to be so qualified or be in good
standing is not reasonably likely to have a material adverse effect on the
condition (financial or otherwise), operations, business or business prospects
of the Company (hereinafter, a "Material Adverse Effect"); no
proceeding has been instituted in any such jurisdiction revoking, limiting or
curtailing, or seeking to revoke, limit or curtail, such power and authority or
qualification; the Company is in possession of and operating in compliance with
all authorizations, licenses, certificates, consents, orders and permits from
federal, state and other regulatory authorities, except where the failure to
possess or be in compliance with any of the foregoing is not reasonably likely
to have a Material Adverse Effect, all of which are valid and in full force and
effect.  Except as set forth in Schedule 5.1, the Company does not own or
control, directly or indirectly, any corporation, association or other
entity.

          5.2  
The Company has full legal right, power and authority to enter into this
Agreement and all agreements required to be entered into hereby, and to perform
the transactions contemplated hereby and thereby.  This Agreement and the
transactions contemplated herein have been duly authorized, executed and
delivered by the Company and, assuming due authorization, execution and delivery
by OSI, are valid and binding agreements on the part of the Company, enforceable
in accordance with their terms, except as may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to or affecting creditors' rights generally or by general equitable
principles.  The execution, delivery and performance of this Agreement by the
Company and the consummation of the transactions herein contemplated will not
conflict with or result in a breach or violation of any of the terms and
provisions of, or constitute a default under, (i) any bond, debenture, note or
other evidence of indebtedness, or under any lease, contract, indenture,
mortgage, deed of trust, loan agreement, joint venture or other agreement or
instrument to which the Company is a party or by which its properties may be
bound, (ii) the Articles of Incorporation or bylaws of the Company or (iii) any
law, order, rule, regulation, writ, injunction, judgment or decree of any court,
administrative agency, regulatory body, government or governmental agency or
body, domestic or foreign, having jurisdiction over the Company or its
properties, except (in any such case) for any conflict, breach, violation or
default which is not reasonably likely to have a Material Adverse Effect.

          5.3  
All outstanding shares of capital stock of the Company have been duly authorized
and validly issued and are fully paid and nonassessable, have been issued in
compliance with all applicable federal and state securities laws, and were not
issued in violation of or subject to any preemptive rights or other rights to
subscribe for or purchase securities.  The 

-5-

issuance and sale of the Shares, Price Adjustment Shares and Warrants have
been duly authorized.  When the Shares, Price Adjustment Shares and Warrant
Shares have been issued and duly delivered as contemplated by this Agreement or
the Warrants, as the case may be, the Shares, Price Adjustment Shares and
Warrant Shares will be validly issued, fully paid and nonassessable, and OSI
will not be subject to personal liability solely by reason of being a holder.
Neither the Shares nor the Warrant Shares will be subject to preemptive rights
of any shareholder of the Company.  The Company has reserved out of its
authorized but unissued Common Shares, solely for the purpose of issue upon
exercise of the Warrants, such number of Common Shares as shall be issuable upon
exercise of the Warrants.  No further approval or authorization of any
shareholder or the Board of Directors of the Company is required for the
issuance and sale of the Shares, the Price Adjustment Shares, the Warrants or
the Warrant.

          5.4  
The authorized capital stock of the Company consists of 100,000,000 Common
Shares, and the Company has no authority to issue any other capital stock.  As
of June 30, 2002, 18,082,703 Common Shares were issued and outstanding, and such
shares are duly authorized, validly issued, fully paid and nonassessable.
Except where the failure to do so would not result in a Material Adverse Effect
on the Company, the offer, issuance and sale of the Common Shares were (a)
registered or qualified under (or were exempt from the registration and
prospectus delivery requirements of) the Act, (b) registered or qualified (or
were exempt from registration or qualification) under the registration or
qualification requirements of all applicable state securities laws, and (c)
accomplished in conformity with all other federal and applicable state or other
jurisdiction's securities laws, rules and regulations.  As of June 30, 2002, the
Company has reserved a total of 3,731,748 Common Shares for issuance to
employees, officers and directors under stock option plans, under which options
to purchase a total of 2,425,994 shares have been granted, but neither exercised
nor forfeited by the holder thereof, the Company has reserved a total of
1,755,614 shares for issuance upon exercise of outstanding warrants issued by
the Company.  Except as expressly provided in this Agreement and as set forth on
Schedule 5.4, the Company has no outstanding subscription, option, warrant,
call, contract, demand, commitment, convertible security or other instrument,
agreement or arrangement of any character or nature whatsoever under which the
Company is or may be obligated to issue Common Shares or other equity security
or instrument convertible into or exchangeable for any equity security (as
hereinafter defined) of any kind.

          5.5  
The Common Shares are quoted on the TSX Venture Exchange, a "qualified market"
as defined in BC Instrument 72-503 of the British Columbia Securities
Commission.

          5.6  
The Company is a "qualifying issuer" as defined in Section 1.1 of the
Multilateral Instrument 45-102 of the Canadian Securities Administrators.

          5.7  
The Company has filed in a timely manner all documents that the Company was
required to file with the Securities and Exchange Commission ("SEC")
under Sections 13, 14(a) and 15(d) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), during the twelve (12) months preceding
the date of this Agreement (collectively, the "SEC Filings").  As of
their respective filing dates (or, if amended, when amended), the documents
filed by the Company with the SEC complied with the requirements of the Exchange
Act.  The consolidated financial statements of the Company included in the
documents filed by 

-6-

the Company with the SEC (the "Financial Statements") comply in all
respects with applicable accounting requirements and with the published rules
and regulations of the SEC with respect thereto.  The Financial Statements have
been prepared in accordance with generally accepted accounting principles
consistently applied ("GAAP") and fairly present the financial
position of the Company at the dates thereof and the results of its operations
and cash flows for the periods then ended (subject, in the case of unaudited
statements, to normal, recurring adjustments and the absence of complete
footnotes).  Except as and to the extent reflected in the Financial Statements,
the Company did not have, as of the date of the Financial Statements, any
liabilities or obligations (other than obligations of continued performance
under contracts and other commitments and arrangements entered into in the
ordinary course of business) which GAAP would require the Company to reflect in
the Financial Statements.  There have not been any changes in the assets,
liabilities, financial condition or operations of the Company from that
reflected in the Financial Statements, except changes in the ordinary course of
business that have not had a Material Adverse Effect.

          5.8  
Except as would not have a Material Adverse Effect, (i) the Company has good
title to all properties and assets described in the SEC Filings as owned by it,
free and clear of any pledge, lien, security interest, encumbrance, claim or
equitable interest, (ii) the material agreements to which the Company is a party
as disclosed in the SEC Filings are valid agreements, enforceable by the
Company, except as the enforcement thereof may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to or affecting creditors' rights generally or by general equitable
principles and, to the Company's knowledge, the other contracting party or
parties thereto are not in material breach or material default under any of such
agreements, and (iii) the Company has valid and enforceable leases for all
properties leased by it, except as the enforcement thereof may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws relating to or affecting creditors' rights generally or by general
equitable principles.  The Company owns or leases all such properties as are
necessary to the Company's operations as described in the SEC Filings.

          5.9  
There is not pending or, to the Company's knowledge, threatened, any action,
suit, claim or proceeding against the Company or any of its officers,
properties, assets or rights before any court, administrative agency, regulatory
body, government or governmental agency or body, domestic or foreign, having
jurisdiction over the Company or any of its officers, properties, or otherwise
which (i) is reasonably likely, individually or in the aggregate, to have a
Material Adverse Effect or is reasonably likely to materially and adversely
affect the Company's properties, assets or rights or (ii) is reasonably likely
to prevent consummation of the transactions contemplated hereby and is not so
disclosed in the SEC Filings.  The Company is not a party or subject to the
provisions of any injunction, judgment, decree or order of any court, regulatory
body, administrative agency, government or governmental agency or body domestic
or foreign, that could reasonably be expected to have a Material Adverse Effect.
The Company has conducted and is conducting its business in compliance with all
applicable federal, state, local and foreign statutes, laws, rules, regulations,
ordinances, codes, decisions, decrees, directives and orders, except where the
failure to do so would not reasonably be likely, singly or in the aggregate, to
have a Material Adverse Effect.

          5.10  
The Company owns or possesses rights to use all patents, patent rights,
inventions, trademarks, service marks, trade names and copyrights and possesses
all of the trade 

-7-

secrets and know-how which are material and necessary to conduct its business
as now conducted and as described in the SEC Filings.  Except as disclosed in
the SEC Filings, the Company has not received any written notice of, nor has any
actual knowledge of, any infringement of or conflict with asserted rights of the
Company by others with respect to any patent, patent rights, inventions, trade
secrets, know-how, trademarks, service marks, trade names or copyrights that are
reasonably likely to have a Material Adverse Effect that would prevent the
Company from carrying out its business substantially as described in the SEC
Filings.  Except as disclosed in the SEC Filings, the Company has not received
any written notice of, nor has it any knowledge of, any infringement of or
conflict with asserted rights of others with respect to any patent, patent
rights, inventions, trade secrets, know-how, trademarks, service marks, trade
names or copyrights which, singly or in the aggregate, if the subject of an
unfavorable decision, ruling or finding, is reasonably likely to have a Material
Adverse Effect that would prevent the Company from carrying out its business
substantially as described in the SEC Filings.

          5.11  
Except as described in the SEC Filings, subsequent to March 31, 2002, there has
not been (i) any material adverse change in the condition (financial or
otherwise), earnings, operations, business or business prospects of the Company
(not including reductions in the cash position of the Company in the ordinary
course consistent with past practices), (ii) any transaction that is material to
the Company, (iii) any obligation, direct or contingent, incurred by the
Company, except obligations incurred in the ordinary course of business, (iv)

consistent with past practices, (v) any dividend or distribution of any kind
declared, paid or made on the capital stock of the Company, (vi) any default in
the payment of principal of or interest on any outstanding debt obligations, or

which has been sustained or will have been sustained which has a Material
Adverse Effect.

          5.12  
The Company is not (a) in violation of its Articles of Incorporation or bylaws
or (b) in default (upon notice or lapse of time or both) in the performance or
observance of any obligation, agreement, covenant or condition contained in any
bond, debenture, note or other evidence of indebtedness, or in any lease,
contract, indenture, mortgage, deed of trust, loan agreement, joint venture or
other agreement or instrument to which it is a party or by which its properties
may be bound, or (c) in violation of any law, order, rule, regulation, writ,
injunction, judgment or decree of any court, government or governmental agency
or body, domestic or foreign, having jurisdiction over the Company or its
properties, except in the case of (b) or (c), for any default or violation not
reasonably likely to have a Material Adverse Effect.

          5.13  
No consent, approval, order or authorization of, or registration, qualification,
designation, declaration or filing with, any federal, state or local
governmental authority on the part of the Company is required in connection with
the consummation of the transactions contemplated by this Agreement
("Consents") except for (a) such Consents which are not material, (b)
compliance with the securities and Blue Sky laws in the states and other
jurisdictions in which Shares are offered and/or sold and in British Columbia,
Canada, which compliance will be effected in accordance with such laws and (c)
Consents and/or filings required by the securities exchange on which the Common
Shares are listed, the British Columbia Securities Commission and the SEC.

-8-

reason to believe, that either it or any of its subsidiaries is not
conducting business in compliance in all material respects with all applicable
laws, rules and regulations of the jurisdictions in which it is conducting
business, including but not limited to, all applicable federal, state and local
environmental laws and regulations, except for any failure to comply which is
not reasonably likely to have a Material Adverse Effect.

          5.14  
No labor disturbance by the employees (as a whole) of the Company exists or, to
the Company's knowledge, is imminent.  The Company is not aware of any existing
or imminent labor disturbance by the employees of any of its principal
suppliers, subcontractors, authorized dealers or international distributors that
is reasonably likely to result in a Material Adverse Effect.  No collective
bargaining agreement exists with any of the Company's employees and, to the
Company's knowledge, no such agreement is imminent.

          5.15  
The Company has timely filed all necessary federal, state and foreign income and
franchise tax returns and have paid all taxes shown thereon as due, and there is
no tax deficiency that has been or, to the Company's knowledge, that might be
asserted against the Company that is reasonably likely to have a Material
Adverse Effect.  All tax liabilities are adequately provided for on the books of
the Company.

          5.16

            
     (i)

in similar businesses, including, but not limited to, insurance covering real
and personal property owned or leased by the Company or its subsidiaries against
theft, damage, destruction, acts of vandalism, products liability, errors and
omissions, and all other risks customarily insured against, all of which
insurance is in full force and effect.  The Company has not been refused any
insurance coverage sought or applied for; and the Company does not have any
reason to believe that it will not be able to renew its existing insurance
coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business at a cost that
would not have a Material Adverse Effect.

            
     (ii)  
The Company now maintains Directors' and Officers' insurance with insurers of
recognized financial responsibility covering any losses and expenses in
connection with any claim arising under the Act, the Exchange Act, Other

applicable to the Company.  Such Directors' and Officers' insurance shall be in

provide less than US$5,000,000 of coverage. 

          5.17  
The Company has been advised concerning the Investment Company Act of 1940, as
amended (the "1940 Act"), and the rules and regulations thereunder,
and is not, and intends in the future to conduct its and its subsidiaries'

and regulations.

("Environmental Laws") which are applicable to its business, except

Adverse Effect, (ii) the Company has not received any written notice from any
governmental authority or third party of an asserted claim under Environmental

quarter.
