Item 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
          RESPECT TO SECURITIES OF THE ISSUER.

     On October 16, 1997, TOSI lent $750,000 to the Issuer (the "Loan")
pursuant to the terms and conditions of a Convertible Loan Agreement (the
"Convertible Loan Agreement").  In connection with the Loan, the Issuer, TOSI
and certain shareholders of the Issuer entered into a Registration Rights
Agreement (the "Registration Rights Agreement") and a Lock-Up Agreement (the
"Lock-Up Agreement"), and the Issuer granted to TOSI Warrants to acquire
shares of the Stock (the "Warrants").  The description in this Item 4 of the
Convertible Loan Agreement, the Registration Rights Agreement, the Lock-Up
Agreement and the Warrants is not, and does not purport to be, complete, and
is qualified in its entirety by reference to such agreements and instruments,
copies of which are filed herewith as Exhibits 99.2, 99.3, 99.4 and 99.5,
respectively.

     The Loan bears interest at an annual rate of 10%, payable quarterly in
arrears, matures on October 16, 1998 (the "Maturity Date") and is secured by
certain assets of the Issuer and certain of its subsidiaries (the
"Subsidiaries"), as well as by unconditional guarantees of the Subsidiaries. 
The original principal amount of the Loan is convertible, at TOSI's option,
at any time and from time to time until the Maturity Date, into 7,000,000
shares of the Stock at the conversion rate of CDN$0.15 (approximately $0.107)
per share.  The Convertible Loan Agreement contain customary anti-dilution
provisions with respect to the Loan's conversion feature.  Although the
appointment of a TOSI-designated person to the Issuer's board of directors
(the "Board") is not specifically required by the Convertible Loan Agreement,
the Issuer has appointed one TOSI-designated person to the Board, and events
of default under the Convertible Loan Agreement include (i) the failure at
any time during the term of the Loan of the Board to include at least one
TOSI-designated director and (ii) an increase in the size of the Board
without the consent of each TOSI-designated Board member.  The Convertible
Loan Agreement also provides for customary events of default.  The Board
waived application of the Issuer's Shareholder Protection Rights Plan in
connection with the contingent issuance of the shares of the Stock
contemplated by the Convertible Loan Agreement and the Warrants. 

     As additional consideration for the Loan, the Issuer granted to TOSI the
Warrants.  The Warrants entitle TOSI to acquire up to 7,000,000 shares of the
Stock at the exercise price of CDN$0.15 (approximately $0.107) per share. 
The Warrants are exercisable, at TOSI's option, at any time and from time to
time until the Maturity Date.  The Warrants contain customary anti-dilution
provisions.

     Pursuant to the Convertible Loan Agreement, TOSI's right to require the
issuance of the Warrants and of the shares of the Stock pursuant to
conversion of the original principal amount of the Loan and/or pursuant to
the exercise of the Warrants was specifically conditioned on the written
approval of the Vancouver Stock Exchange of the terms and conditions of the
Loan and of the transactions contemplated thereby.  The Issuer received such
written approval on October 29, 1997.

     Pursuant to the Registration Rights Agreement, the Issuer granted TOSI
certain registration rights with respect to the shares of Stock issuable upon
conversion of the original principal amount of the Loan and upon exercise of
the Warrants.  Pursuant to the Registration Rights Agreement, holders of at
least 25% of all Registrable Securities (as defined therein) may make up to
a total of four demands (of which TOSI and its transferees are entitled to
make a total of two) for registration of the Registrable Securities under the
Act (or, alternatively, for qualification of the Registrable Securities for
distribution pursuant to the securities laws of the provinces of British
Columbia or Ontario) at the Issuer's expense during the six-year term
thereof.  Additionally, the Registration Rights Agreement provides for
incidental registration rights with respect to the Registrable Securities in
the event that the Issuer proposes to register any securities of the same
class as the Registrable Securities, subject to customary exceptions and cut-
backs.  The Registration Rights Agreement also contains customary
indemnification and contribution provisions.

     Section 1.02   Accounting Principles.  Any and all determinations of the
character or amount of any asset or liability or item of income or expense
required to be determined or any consolidation or other accounting
computation required to be made under this Agreement shall be made in
accordance with GAAP applied on a basis consistent with the Financial
Statements, except to the extent that such principles are inconsistent with
the requirements of this Agreement.  All determinations of financial amounts
on the consolidated basis of the Borrower and its Subsidiaries shall make due
allowance for any minority stock interest in such Subsidiaries.

     Section 1.03   Currency.  Except where a reference to Canadian currency
is indicated by the use "CDN," all currency references in this Agreement are
references to the lawful moneys of the United States of America and where,
for any purpose in connection with the Loan, it is necessary to refer to the
lawful moneys of Canada, a deemed exchange rate of CDN$1.40 per US$1.00 shall
apply so that, for example, the original principal amount of the Loan
expressed in Canadian funds is CDN$1,050,000.00.

execution, delivery and performance of this Agreement and of the Ancillary
Documents has been duly and effectively taken.  All corporate action on each
Subsidiary's part necessary for the due execution, delivery and performance
of the Ancillary Documents to which it is a party has been duly and

     Section 3.03   Binding Obligations.  This Agreement, the Note, the
Warrant and the Ancillary Documents to which the Borrower is a party
constitute valid and binding obligations of the Borrower, enforceable against
the Borrower in accordance with their respective terms (except to the extent

similar laws of general application affecting the enforcement of creditors'
rights). Each Ancillary Document to a Subsidiary is a party constitutes the
valid and binding obligations of such Subsidiary, enforceable against such
Subsidiary in accordance with its terms (except to the extent that
enforcement may be subject to any applicable bankruptcy, insolvency or
similar laws of general application affecting the enforcement of creditors'
rights).

     Section 3.04   No Legal Bar or Resultant Lien.  The Borrower's

incorporation or charter, bylaws or any contract, agreement, instrument or
Governmental Requirement to which the Borrower is subject (other than any
Governmental Requirement the violation of which, either individually or in
the aggregate, would not have a Material Adverse Effect), or result in the
creation or imposition of, or obligation to create, any Lien upon any
Property of the Borrower, other than any Lien permitted by this Agreement.

Documents to which it is a party does not and shall not violate any

Subsidiary, other than any Lien permitted by this Agreement.

     Section 3.05   No Consents.  Neither the Borrower's execution, delivery
and performance of the Note, the Warrant, this Agreement and the Ancillary

delivered to the Lender, have been prepared in accordance with GAAP,
consistently applied on a basis consistent with past practice, and fully and
accurately present the financial condition and changes in financial position
of the Borrower and its Subsidiaries as at the date or dates and for the
period or periods therein stated, subject only to typical year-end audit

the Borrower or any Subsidiary.

     Section 3.09   Taxes; Governmental Charges.  The Borrower and its

value thereof and (iii) Liens in favor of the Lender or otherwise
specifically permitted or contemplated by this Agreement or the Security
Instruments.

     Section 3.11   Defaults.  Neither the Borrower nor any Subsidiary is in
default, nor has any event or circumstance occurred that, with the passage of
time or the giving of notice or both would constitute a default, under any
loan or credit agreement, indenture, mortgage, deed of trust, security
agreement or other agreement or instrument evidencing or pertaining to any
obligation for the payment of money of the Borrower or any Subsidiary, or
under any material agreement or other instrument to which the Borrower or any

government or any agency thereof, riot, activities of armed forces or acts of
God or of any public enemy.

     Section 3.13   Compliance with the Law.  Neither the Borrower nor any
Subsidiary:

          (a)  is in violation of any Governmental Requirement (other than
     any Governmental Requirement the failure to be in compliance with which,
     either individually or in the aggregate, would not have a Material
     Adverse Effect); or

          (b)  has failed to obtain any license, permit, franchise or other
     governmental authorization necessary to the ownership of any of its
     Property or the conduct of its business;

were asserted by any Person through appropriate action) a Material Adverse
Effect.

     Section 3.14   ERISA.  The Borrower and its Subsidiaries are in
compliance with the applicable provisions of ERISA, and no "reportable
event," as such term is defined in Section 4043 of ERISA, has occurred with
respect to any Plan of the Borrower or any Subsidiary.

     Section 3.15   Capitalization.

     (a)  The Borrower's issued and outstanding capital stock consists solely
of the capital stock set forth in Schedule 3.15 hereto.  The Borrower has not
issued, or agreed to issue, any Shares or any securities convertible into, or
exchangeable with, Shares or entered into, issued or granted, or agreed to
enter into, issue or grant, any rights, plans, options, warrants or
agreements for the purchase or acquisition (whether or not contingent) of any
capital stock (collectively, "Stock Rights") other than as set forth in such
Schedule 3.15.  All of the Borrower's issued and outstanding capital stock
was duly authorized and validly issued and is fully-paid and nonassessable. 
All of the Borrower's issuances of its capital stock and Stock Rights were
made in compliance with all applicable laws and with VSE rules and
regulations.  
     (b)  Except as to Petrovalve International (Barbados) Inc., of which the
Borrower owns beneficially and of record 98% of the issued and outstanding
capital stock, the Borrower owns, directly or indirectly, 100% of the issued
and outstanding capital stock of all of the Subsidiaries.  All of the capital
stock of each Subsidiary was duly authorized and validly issued and is fully-
paid and nonassessable.  The capital stock of Petrovalve International Inc.,
an Alberta corporation, Petrovalve, Inc., a Delaware corporation, USA
Petrovalve, Inc., a Texas corporation, and Turbeco, Inc., a Texas
corporation, that has been pledged to the Lender as part of the security for
the Loan constitutes all of the capital stock of such corporations.  No
Subsidiary has issued, or agreed to issue, any shares of capital stock or any
securities convertible into, or exchangeable with, shares of capital stock or
entered into, issued or granted, or agreed to enter into, issue or grant, any
Stock Rights.

     Section 3.16   Trade Rights.  There are no pending or threatened claims
against the Borrower or any Subsidiary alleging infringement of, or conflict
with the rights of others under, any patent, patent application, trademark,
service mark, copyright, trade secret or similar intangible franchise,
license or right (collectively, "Trade Rights") and, to the best of the
Borrower's knowledge, no reasonable basis exists for any such allegation.

     Section 3.17   Necessary Approvals.  The Borrower and each Subsidiary
validly holds all permits, licenses, approvals and Trade Rights necessary or
desirable to enable it to conduct its business as it is currently conducted.

     Section 3.18   No Material Misstatements.  No information that the
Borrower or any Subsidiary has furnished to the Lender in any form in
connection with the negotiation of this Agreement contained or contains any
material misstatement of fact or omitted or omits to state a material fact or
any fact necessary to make the statements contained therein not misleading.

the obligations, if any, of the Lender hereunder shall immediately terminate,
and the entire amount of all Indebtedness then outstanding shall become
automatically and immediately due and payable, all without written notice and
without presentment, demand, protest, notice of protest or dishonor, notice
of intention to accelerate, notice of acceleration or any other notice of
default of any kind, all of which are hereby expressly waived by the
Borrower.  Upon the occurrence and at any time during the continuance of any
other Event of Default, by written notice to the Borrower the Lender may (i)
declare all Indebtedness to be immediately due and payable without
presentment, demand, protest, notice of protest or dishonor, notice of
intention to accelerate or other notice of default of any kind, all of which

waived by the Borrower), to set-off and apply any and all moneys at any time
held and other indebtedness at any time owing by the Lender to the Borrower
against any and all of the Indebtedness of the Borrower, irrespective of
whether or not the Lender shall have made any demand under this Agreement or
the Note and although such obligations may be unmatured.  The Lender agrees
promptly to notify the Borrower after any such setoff and application,
provided that the failure to give such notice shall not affect the validity
of such set-off and application.  The rights of the Lender under this Section
are in addition to other rights and remedies (including, without limitation,
other rights of set-off) that the Lender may have.

     documents or their respective analogues, certificates of existence and

transfer to such account as the Borrower reasonably shall request.

     Section 7.04   Subsequent Deliveries.  Notwithstanding anything to the

the necessity of having the Closing occur at the earliest possible time, the
Borrower may not be able to satisfy all of the conditions precedent to the
Closing required by Section 7.02 prior to or at the Closing.  In
consideration of the Lender's willingness to close the Loan without such

satisfy all of such conditions precedent required pursuant to Section 7.02
but not satisfied prior to or at the Closing as soon as possible following
the Closing, but in any event no later than fifteen (15) Business Days
thereafter, except that consummation of the Private Placement referenced in
Section 7.02(e) must occur in any event no later than thirty (30) Business
Days thereafter.

                            Form of Promissory Note


October ___, 1997                                                
US$750,000.00


     FOR VALUE RECEIVED, FLOTEK INDUSTRIES INC., an Alberta corporation
("Borrower"), promises to pay to the order of TOSI, L.P., a Texas limited
partnership ("Lender"), on or before October ___, 1998, at its office at 3900
Thanksgiving Tower, 1601 Elm Street, Dallas, Texas 75201, or at such other
location as Lender may designate, in immediately available funds, SEVEN
HUNDRED FIFTY THOUSAND AND NO/100 UNITED STATES DOLLARS (US$750,000.00). 
Borrower will also pay interest on the unpaid principal balance outstanding
from time to time at a fixed rate of ten percent (10%) per annum, payable
quarterly in arrears.

     Interest will be computed on the basis of the actual number of days
elapsed and a year comprising 360 days, unless such calculation would result
in a usurious interest rate, in which case such interest will be calculated
on the basis of a 365 or 366 day year, as the case may be.

     All past due principal and interest on this Note will, at Lender's
option, bear interest at the maximum nonusurious rate of interest ("Highest
Lawful Rate") or, if applicable law does not provide for a maximum
nonusurious rate of interest, at a rate per annum equal to 18%.

     Borrower covenants to apply the total amount advanced by Lender
hereunder only in the manner set forth in that certain Convertible Loan
Agreement of even date herewith between Borrower and Lender (the "Loan
Agreement").  Borrower understands and acknowledges that Lender would not be
willing to make the loan evidenced hereby but for Borrower's covenant set
forth in the immediately-preceding sentence.

     All undefined capitalized terms used in this Note shall have the
meanings respectively ascribed to them in the Loan Agreement.

     In addition to all principal and accrued interest on this Note, Borrower
agrees to pay: (a) all reasonable costs and expenses incurred by or on behalf
of Lender and all owners and holders of this Note in attempting to collect
this Note through probate, reorganization, bankruptcy or any other
proceeding; and (b) reasonable attorneys fees if and when this Note is placed
in the hands of an attorney for collection.

     The outstanding principal amount of the Loan evidenced by this Note
shall be convertible into common shares of Borrower in the manner and to the
extent set forth in the Loan Agreement.

     Borrower and Lender intend to conform strictly to applicable usury laws. 
Therefore, the total amount of interest (as defined under applicable law)
contracted for, charged or collected under this Note will never exceed the
Highest Lawful Rate.  If Lender contracts for, charges or receives any excess
interest, it will be deemed a mistake.  Lender will automatically reform the
contract or charge to conform to applicable law and, if excess interest has
been received, Lender will either refund the excess to Borrower or credit the
excess on the unpaid principal amount of this Note.  All amounts constituting
interest will be spread throughout the full term of this Note in determining
whether interest exceeds lawful amounts.

     The unpaid principal balance of this Note at any time will be the total
amount advanced by Lender, less the amount of all payments of principal. 
Borrower may at any time pay the full amount of this Note without the payment
of any premium, penalty or fee. 

     "Loan Document" means this Note and any document or instrument
evidencing, securing, guaranteeing or given in connection with this Note
including, without limitation, the Loan Agreement, the Warrant and the
Registration Rights Agreement.  "Obligations" means all principal, interest
and other amounts which are or become owing under this Note or any other Loan
Document.  "Obligor" means Borrower and any guarantor, surety, co-signer, or
other person who may now or hereafter be obligated to pay all or any part of
the Obligations.  Where appropriate, the masculine gender includes the
feminine and the neuter and the singular number includes the plural number.

     Each Obligor severally waives notice, demand, presentment for payment,
notice of nonpayment, notice of intent to accelerate, notice of acceleration,
protest, notice of protest and the filing of suit and diligence in collecting
this Note and all other demands and notices, and consents and agrees that its
liabilities and obligations will not be released or discharged by any or all
of the following, whether with or without notice to it or any other Obligor,
and whether before or after the stated maturity hereof: (i) extensions of the
time of payment; (ii) renewals; (iii) acceptances of partial payments; (iv)
releases or substitutions of any collateral or any Obligor; and (v) failure,
if any, to perfect or maintain perfection of any security interest in any
collateral.  Each Obligor agrees that acceptance of any partial payment will
not constitute a waiver and that waiver of any default will not constitute
waiver of any prior or subsequent default.  

     This Note is governed by the laws of the Province of Alberta (exclusive
of any such laws that pertain to conflicts of laws).  If any provision of
this Note is illegal or unenforceable, that illegality or unenforceability
will not affect the remaining provisions of this Note.  BORROWER(S) AND
LENDER AGREE THAT THIS NOTE WILL BE PERFORMED IN DALLAS COUNTY, TEXAS, AND
THAT SUCH COUNTY IS PROPER VENUE FOR ANY ACTION OR PROCEEDING BROUGHT BY
BORROWER(S) OR LENDER, WHETHER IN CONTRACT, TORT, OR OTHERWISE.  ANY ACTION
OR PROCEEDING AGAINST BORROWER(S) MAY BE BROUGHT IN ANY STATE OR FEDERAL
COURT IN SUCH COUNTY TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW.  TO THE
EXTENT PERMITTED BY APPLICABLE LAW, BORROWER(S) HEREBY IRREVOCABLY (A)
SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF SUCH COURTS, AND (B) WAIVES ANY
OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH ACTION OR
PROCEEDING BROUGHT IN ANY SUCH COURT OR THAT ANY SUCH COURT IS AN
INCONVENIENT FORUM.  BORROWER(S) AGREES THAT SERVICE OF PROCESS UPON IT MAY

<PAGE>
                                 Schedule 2.04

                                   Conversion

     1.   Conversion Right.  The Borrower hereby grants to the Lender the
sole and exclusive right and option (the "Conversion Right") to convert, at
any time and from time to time until 4:00 p.m. Vancouver, British Columbia,
Canada time on the maturity date of the Note, in whole or in part, the then-
outstanding principal amount of the Note (the "Principal Balance") into a
maximum of 7,000,000 Shares at the price of CDN$0.15 per Share (the
"Conversion Price"), subject to adjustment as hereinafter provided.

     2.   Manner of Exercise of Conversion Right.

     (a)  On each occasion on which the Lender desires to convert all or a
portion of the Principal Balance into Shares, the Lender shall deliver a
written notice (the "Notice of Exercise") to the Borrower specifying:

     (i)  the amount of the Principal Balance to be converted, expressed in
     Canadian dollars; and

     (ii) , with respect to each Person in whose name the Lender wishes
     Shares to be issued, such Person's exact name, address, telephone number
     and social security number or taxpayer identification number and, if
     such Person is other than a natural person, the name of a natural person
     authorized to act on such Person's behalf.

     (b)  Upon receipt of a Notice of Exercise, the Borrower shall promptly:

     (i)  direct its transfer agent to issue one or more certificates
     representing the Shares into which the portion of the Principal Balance
     referenced in subsection (a)(i) above is then convertible to the
     respective Persons and in the respective amounts set forth in the Notice
     of Exercise;

     (ii) deliver such certificates to such Persons at the addresses
     specified in the Notice of Exercise; and

     (iii)     if applicable, deliver to the Lender a check for any amount
     payable in lieu of fractional shares pursuant to Section 4 below.

     3.   Capital Adjustments.

     The Shares issuable upon conversion of part or all of the original
principal amount of the Note is subject to the following adjustments:  

     (a)  Recapitalization, Reclassification and Succession.  If any
recapitalization of the Borrower or reclassification of its Shares or any
merger or consolidation of the Borrower into or with a corporation or other
business entity, or the sale or transfer of all or substantially all of the
Borrower's assets or of any successor corporation's assets to any other
corporation or business entity (any such corporation or other business
entity's being included within the meaning of the term "successor
corporation") shall be effected at any time while any principal amount of the
Note remains outstanding then, as a condition of such recapitalization,
reclassification, merger, consolidation, sale or transfer, lawful and
adequate provision shall be made whereby the Lender thereafter shall have the
right to receive upon the conversion of the principal amount of the Note then
outstanding (at a given time, the "Principal Balance") and in lieu of the
Shares immediately theretofore issuable upon the conversion of the Principal
Balance, such shares of capital stock, securities or other property as may be
issued or payable with respect to or in exchange for a number of outstanding
Shares equal to the number of Shares immediately theretofore issuable upon
the conversion of the Principal Balance had such recapitalization,
reclassification, merger, consolidation, sale or transfer not taken place
and, in each such case, the terms of the Loan Agreement shall be applicable
to the shares of capital stock or other securities or property receivable
upon the conversion of the Principal Balance after such consummation.

     (b)  Subdivision or Combination of Shares.  If, at any time while any
principal amount of the Note remains outstanding, the Borrower shall
subdivide or combine its Shares, the number of Shares purchasable upon
conversion of the Principal Balance shall be proportionately adjusted.

     (c)  Certain Dividends and Distributions.  If, at any time while any
principal amount of the Note remains outstanding, the Borrower shall take a
record of the holders of Shares for the purpose of entitling them to receive
a dividend payable in, or other distribution of, Shares, then the number of
Shares purchasable upon conversion of the Principal Balance shall be adjusted
to that number determined by multiplying the number of Shares so purchasable
immediately prior to such record date by a fraction (i) the numerator of
which shall be the sum of (A) the total number of outstanding Shares
immediately prior to such record date and (B) the total number of Shares
issuable pursuant to such dividend or distribution, and (ii) the denominator
of which shall be the total number of Shares outstanding immediately prior to
such record date.

     (d)  Corresponding Conversion Price Adjustment.  Whenever the number of
Shares purchasable upon the conversion of the Principal Balance is increased
or decreased as provided in subsections (b) or (c) above, the Conversion
Price shall be adjusted by multiplying the Conversion Price immediately prior
to such adjustment by a fraction, the numerator of which shall be the number
of Shares purchasable upon the conversion of the Principal Balance
immediately prior to such adjustment, and the denominator of which shall be
the number of Shares purchasable immediately thereafter.

     (e)   Certain Shares Excluded.  The number of Shares outstanding at any
given time for purposes of the adjustments set forth in this Section shall
exclude any shares then directly or indirectly held in the treasury of the
Borrower.

     (f)  Deferral and Cumulation of De Minimis Adjustments.  The Borrower
shall not be required to make any adjustment of the Conversion Price pursuant
to this Section if the amount of such adjustment would be less than one
percent (1%) of the Conversion Price in effect immediately before the event
that would otherwise have given rise to such adjustment.  In such case,
however, any adjustment that otherwise would have been required to be made
shall be made at the time of and together with the next subsequent adjustment
which, together with any adjustment or adjustments so carried forward, shall
amount to not less than one percent (1%) of the Conversion Price in effect
immediately before the event giving rise to such next subsequent adjustment.

     (g)  Duration of Adjusted Conversion Price.  Following each computation
or readjustment of an adjusted Conversion Price as provided in this Section,
the new adjusted Conversion Price shall remain in effect until a further
computation or readjustment thereof is required.

     4.   Notices to Lender.

     (a)  Notice of Record Date.  In case:

          (i)  the Borrower shall take a record of the holders of Shares (or
     other capital stock or securities at the time receivable upon the
     exercisable of the Principal Balance) for the purpose of entitling them
     to receive any dividend (other than a cash dividend payable out of
     earned surplus of the Borrower) or other distribution, or any right to
     subscribe for or purchase any shares of stock of any class or any other
     securities, or to receive any other right; or

          (ii) of any capital reorganization of the Borrower, any
     reclassification of the capital stock of the Borrower, any consolidation
     with or merger of the Borrower into another corporation, or any
     conveyance of all or substantially all of the assets of the Borrower to
     another corporation; or

          (iii)     of any voluntary dissolution, liquidation or winding-up
          of the Borrower;
  
then, and in each such case, the Borrower shall mail or cause to be mailed to
the Lender a notice specifying, as the case may be, (1) the date on which a
record is to be taken for the purpose of such dividend, distribution or
right, and stating the amount and character of such dividend, distribution or
right or (2) the date on which such reorganization, reclassification,
consolidation, merger, conveyance, dissolution, liquidation or winding-up is
to take place, and the time, if any, is to be fixed, as of which the record
holders of Shares shall be entitled to exchange their Shares (or such other
capital stock or securities) for securities or other property deliverable
upon such reorganization, reclassification, consolidation, merger,
conveyance, dissolution, liquidation or winding-up.  Such notice shall be
mailed at least 30 days prior to the record date therein specified or, if no
record date shall have been specified, at least 30 days prior to such other
specified date.

     (b)  Notice of Adjustments.  Whenever any Conversion Price shall be
adjusted pursuant to Section 3 hereof, the Borrower shall promptly deliver to
the Lender a certificate signed by its President or by any Vice President,
and by its Treasurer or any Assistant Treasurer or its Secretary or any
Assistant Secretary, setting forth in reasonable detail the event requiring
the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated and the Conversion Price after giving effect to
such adjustment. 

     5.   No Requirement to Issue Fractional Shares.  The Borrower shall not
be required to issue fractional Shares upon conversion of part or all of the
Principal Balance pursuant to the Lender's exercise of the Conversion Right. 
In lieu thereof, the Borrower shall be entitled to pay to the Lender in cash
an amount equal (to the nearest cent) to the appropriate fraction of the
value (which shall be the last reported sale price if a sale took place
within 60 days of the applicable Notice of Exercise or, if none, a deemed
value of CDN$0.15 per Share) of a Share on the date that the Borrower
receives the Notice of Exercise.

                                 Schedule 4.16

       Right of First Refusal with respect to Future Borrower Financings


          1.01 The Borrower will give written notice (a "Notice") to
the Lender of the terms of any further financing (in each case, a
"Financing") that it requires or proposes to obtain by way of a public or
private offering of its securities (including, without limitation, equity,
debt or derivative securities) during the twenty-four (24) months (the
"Term") next following the Closing Date.

         1.02 Each Notice will contain the material terms and conditions of the
proposed Financing, including without limitation the proposed price and the
nature and size thereof.

          1.03 The Lender will have the right of first refusal to provide up to
37.5% (the "Lender's Proportionate Share") of any Financing during the Term.

          1.04 The right of first refusal must in each instance be exercised by
the Lender within thirty (30) days next following receipt of the applicable
Notice by giving the Borrower written notice (an "Exercise Notice') that the
Lender will provide the Lender's Proportionate Share of the Financing, in
whole or in part, on the terms set forth in the Notice.

          1.05 Immediately upon receipt of any Exercise Notice, Borrower will:

          (a)  provide a copy of same to each of Marlin Investors, L.L.C. and
               Charles Dickinson ("Other Rightholders"), who have been granted
               rights of first refusal pursuant to agreements (the "Other
               Agreements") made between the Other Rightholders and  Borrower
               in connection with the financing announced by the Borrower on
               September 14, 1997 to provide up to 50.0% and 12.5% (the "Other
               Rightholders' Proportionate Shares"), respectively, of any
               Financing proposed during the Term; and

          (b)  provide copies of the exercise notices (the "Other Exercise
               Notices") given to the Borrower by Other Rightholders pursuant
               to the Other Agreements;

and in the event that the Borrower does not receive an Exercise Notice or one
or both of the Other Exercise Notices in respect of a Financing, the Borrower
will give notice (in each case a "Second Notice") to such effect to the
Lender and/or one or both of the Rightholders, as circumstances require.

          1.06 If the Lender fails to give an Exercise Notice within thirty (30)
days next following receipt of the applicable Notice or elect in an Exercise
Notice to provide less than the Lender's Proportionate Shares of such
Financing, the Borrower will then be free for a period of (3) months (subject
to the rights of the Other Rightholders to provide the Other Rightholders'
Proportionate Shares of such proposed Financing as a result of the timely
giving of notice of their intention to do so and their rights under the Other
Agreements) to make other arrangements to obtain the unfunded portion of the
proposed Financing from another source, including the Other Rightholders, on
the same terms or on terms no less favorable to the Borrower than are set
forth in the applicable Notice.

         1.07 In the event that one or both of the Other Rightholders elects not
to provide all such Other Rightholder's Proportionate Share of such
Financing, the Lender may, by further notice to the Borrower given not later
than ten (10) days after the Lender's receipt of the Other Exercise Notices
or Second Notices, as the case may be, elect to provide some or all of that
portion of the Financing (the "Remaining Financing") which one or both of the
Other Rightholders (a "Non-participating Rightholder") has not elected to
provide; provided, however, that if one of the Other Rightholders (the
"Participating Rightholder") also elects to provide some or all of the
Remaining Financing, and if the additional elections of the Lender and the
Participating Rightholder are greater in the aggregate than the Remaining
Financing, then the Lender and the Participating Rightholder shall share in
the Remaining Financing pro rata according to their percentage interests set
forth herein.

          1.08 The failure by Lender in any one or more instances to provide all
or any portion of the Lender's Proportionate Share of any Financing shall not
deprive the Lender of its right of first refusal in any other instances.

          1.09 The right of first refusal granted hereunder is conditional upon
consummation of the Closing.

          1.10 The right of first refusal granted hereunder will not affect the
Borrower's right to obtain fiscal agency or investment banking services that
it requires or proposes to obtain during the Term, whether or not in
connection with any Financing or any proposed amalgamation, merger,
acquisition, takeover, plan of arrangement or other restructuring, including,
without limitation, the preparation of fairness opinions and the like.

          1.11 The Borrower will not amend the terms of or grant extensions of
time in respect of any rights of first refusal previously granted or which
may hereafter be granted to either of the Other Rightholders pursuant to the
Other Agreement without, at the option of the Lender, amending the terms of
or granting extensions of time in respect of the right of first refusal
granted to the Lender hereunder in the same manner and to the same extent as
the Borrower has agreed to amend the terms of one or both of the Other
Agreements or to grant any extension of time in respect of one or both of the
Other Agreements.

closing of such transactions that the parties hereto enter into this
Agreement.  Capitalized terms used herein but not otherwise defined shall

herein are US Dollars, unless otherwise noted.

          I.   Registration under Securities Act, Etc.

               1.1  Registration on Request.

                    (a)  Request.  At any time, or from time to time, upon the
written request of one or more of the Principal Shareholders holding 25% or
more of the Registrable Securities (the "Initiating Holders") that the
Company either, as directed by the Initiating Holders, (i) effect eh
registration under the Securities Act or (ii) file a prospectus (which for
the purposes of this agreement shall include a statement of material facts or
short form prospectus) for the purposes of qualifying for distribution in
British Columbia or Ontario pursuant to Applicable Canadian Securities Laws
(any such registration or prospectus filing being hereinafter referred to as
"registration," and any such registration statement or prospectus being
hereinafter referred to as a "registration statement") of all or part of such
Initiating Holders' Registrable Securities, the company promptly will give
written notice of such requested registration of all of the other Principal
Shareholders, and thereupon the Company will use reasonable efforts to
effect, at the earliest possible date, the registration under the Securities
Act or the Applicable Canadian Securities Laws, as directed by the Initiating
Holders in their request, of (i) the Registrable Securities which the Company
has been so requested to register by such Initiating Holders, and (ii) all
other Registrable Securities which the company has been requested to register
by the other Principal Shareholders (such holders together with the
Initiating Holders hereinafter are referred to as the "Selling Holders") by
written request given to the Company within 30 days after the giving of such
written notice by the Company, all to the extent requisite to permit the
disposition of the Registrable Securities so t be registered.

                    (b)  Registration of Other Securities.  Whenever the Company
shall effect a registration pursuant to this Section 1.1, no securities other
than Registrable Securities held by Principal Shareholders shall be included
among the securities covered by such registration unless Selling Holders of
greater than 51% of the registrable Securities to be included in such
registration shall have consented in writing to the inclusion of such other
securities, which consent shall not be unreasonably withheld or delayed,
provided, however, that no such other securities shall be included in such
registration to the extent that such inclusion would reduce the number of
Registrable Securities in such registration that any Selling Holder has
requested be included therein.

                    (c)  Registration Statement Form.  Registrations under this
Section 1.1 shall be on such appropriate registration form of the Commission
or the form required under Applicable Canadian Securities Laws, as the case
may be, as shall be reasonably selected by the Company.

                    (d)  Effective Registration Statement.  A registration
requested pursuant to this Section 1.1 shall not be deemed to have been
effected unless a registration statement with respect thereto has become
effective and remained effective in compliance with the provisions of the
Securities Act or Applicable Canadian Securities Laws, as the case may be,
with respect to the disposition of all Registrable Securities covered by such
registration statement for a period of at least 90 days.

                 (e)  Section of Underwriters.  The underwriter or underwriters
of each underwritten offering of the Registrable Securities so to be
registered shall be selected by the Selling Holders of at least 50% of the
registrable Securities to be included in such registration and shall be
reasonably acceptable to the Company.

                    (f)  Priority in Requested Registration.  If the managing
underwriter of an underwritten offering shall advise the Company in writing
(and the Company shall so advise each Selling Holder of Registrable
Securities requesting registration of such advice) that, in its opinion, the
number of securities requested to be included in such registration is
sufficiently large to materially adversely effect the success of the
offering, the Company, except as provided in the following sentence, will
include in such registration, to the extent of the number and type which the
Company is so advised can be sold in such offering, Registrable Securities
requested to be included in such registration on the following basis;

               (i)  first, pro rata among the Initiating Holders; and

               (ii) second, pro rata among the other Selling Holders.

As used herein, the term "pro rata" among a particular group of shareholders
shall mean allocated among such shareholders proportionally, on the basis of
the number of Registrable Securities held by each shareholder in such group
as compared to the total number of Registrable Securities held by all
shareholders in such group.  To the extent that all the Registrable
Securities of Selling Holders so requested to be registered are excluded from
the offering, the holders of such Registrable Securities shall be deemed not
to have used a demand registration pursuant to this Section 1.1.

                 (g)  Limitations on Registration on Request.  Notwithstanding
anything in this Section 1.1 to the contrary, the Company shall not be
required to take any action to file a registration statement pursuant to this
Section 1.1:

             (i)  within 120 days following the effective date of any registered
          offering of the Company's securities;

               (ii) with respect to any offering having an aggregate sales price
          (before deduction of underwriting discounts and expenses of sale) of
          less than $500,000;

              (iii)     with respect to any offering having an aggregate sales
         price (before deduction of underwriting discounts and expenses of sale)
        of more than $10,000,000 unless such offering is firmly underwritten; or

              (iv) after (A), with respect to Marlin and Dickinson, the Company
         has effected two such registrations at the request of Marlin and/or
        Dickinson or their transferees and with respect to TOSI, the Company has
        effected two such registrations at the request of TOSI or its
        transferees (representing an aggregate of four such registrations on
        behalf of all holders of Registrable Securities), (B) the Company has
        effected such a registration at the request of any Principal Shareholder
          within the previous six months, (C) the Principal Shareholders making
          such request hold fewer than 100,000 shares of Registrable Securities,
          or (D) the expiration of the term of this Agreement.

                  (h)  Expenses.  The Company will pay all Registration Expenses
in connection with any registration requested pursuant to this Section 1.1.

               1.2  Piggy-Back Registration.

                   (a)  Right to Include Registrable Securities.  If the Company
at any time proposes to file a registration statement to register any of its
securities of the same class as the Registrable Securities under the
Securities Act or the Applicable Canadian Securities Laws (except for a
registration statement or prospectus filed in connection with an employee
benefit plan, a transaction relating to a merger or business combination, a
transaction relating to an exchange offer, a transaction relating to an
acquisition of assets or securities, or a transaction otherwise described in
Rule 145 of the Securities Act), whether or not for sale for its own account,
it will each such time give prompt written notice to all holders of
Registrable Securities of its intention to do so and of such holders' rights
under this Section 1.2.  Upon the written request of nay such holder (a
"Requesting Holder") (which request shall specify the amount of Registrable
Securities intended to be disposed of by such Requesting Holder) made as
promptly as practicable and in any event within 20 days after the receipt of
any such notice (15 days if the Company states in such written notice or
gives telephonic notice to all registered holders of Registrable Securities,
with written confirmation to follow promptly thereafter, stating that (i)
such registration will be on Form S-3 and (ii) such shorter period of time is
required because of a planned filing date), the Company will use reasonable
efforts to effect the registration or file the prospectus under the
Securities Act or the Applicable Canadian Securities Laws, as the case may
be, of all Registrable Securities which the Company has been so requested to
register by the Requesting Holders thereof.  No registration effected under
this Section 1.2 shall relieve the Company of its obligation to effect any
registration upon request under Section 1.1.

                    (b)  Priority in Incidental Registrations.  If the managing
underwriter of any underwritten offering shall deliver a written opinion to
the holders of registrable Securities that the total amount of Registrable
Securities requested to be included in such registration would have a
material adverse effect on such offering then the Company will include in
such registration, to the extent the number which the Company is so advised
can be sold in(or during the time of) such offering, first, all securities
proposed by the Company to be sold for its own account, and second, such
Registrable Securities requested to be include in such registration pursuant
to this Agreement, pro rata among Requesting Holders; provided that if
securities are being offered for the account of other persons or entities as
well as the Company, such reduction shall not represent a greater fraction of
the number of securities intended to be offered by holders of Registrable
Securities than the fraction of similar reductions imposed on such other
persons or entities over the amount of securities they intended to offer.

                  (c)  Expenses.  The Company will pay all Registration Expenses
in connection with any registration effected pursuant to this Section 1.2.

               1.3  Registration Procedures.  If and whenever the Company is
required to effect the registration of any registrable SECURITIES under the
Securities Act or the Applicable Canadian Securities Laws as provided in
Sections 1.1 and 1.2 the Company will, as expeditiously as possible, use
reasonable efforts to:

                  (i)  prepare and (within 120 days after the end of the period
             within which requests for registration may be given to the Company
             or in any event as soon thereafter as practicable) file with the
             Commission or the Canadian Securities regulations the requisite
             registration statement to effect such registration and thereafter
             use reasonable efforts to cause such registration statement to
             become effective;

                    (ii) prepare and file with the Commission or the Canadian
               Securities Regulators such amendments and supplements to such
               registration statement and the prospectus used in connection
               therewith as may be necessary to keep such registration statement
               effective and to comply with the provisions of the Securities Act
               or the Applicable Canadian Securities Laws, as the case may be,
               with respect to the disposition of all Registrable Securities
              covered by such registration statement for a period of at least 90
               days;

                    (iii)     furnish to each seller of Registrable Securities
               covered by such registration statement, such number of conformed
               copies of such registration statement and of each such amendment
              and supplement thereto (in each case including all exhibits), such
               number of copies of the prospectus contained in such registration
               statement (including each preliminary prospectus and any summary
             prospectus) and any other prospectus filed under rule 424 under the
               Securities Act, in conformity with the requirements of the
               Securities Act or the Applicable Canadian Securities Laws, as the
               case may be, and such other documents, as such seller may
               reasonably request;

                   (iv) register or qualify all Registrable Securities and other
               securities covered by any registration statement under the
               Securities Act, under Applicable Canadian Securities Laws, under
             such other securities or blue sky laws of such States of the United
               States of America where an exemption is not available and as the
               sellers of Registrable Securities covered by such registration
               statement shall  reasonably request; keep such registration or
             qualification in effect for so long as such registration statement
               remains in effect; and take any other action which may be
               reasonably necessary or advisable to enable such seller to
               consummate the disposition in such jurisdiction of the securities
               to be sold by such sellers, except that (x) the Company shall not
               for any such purpose be required to qualify generally to do
               business as foreign corporation in any jurisdiction wherein it
               would not but for the requirements of this subdivision (iv) be
               obligated to be so qualified or to consent to general service of
               process in any such jurisdiction and (y) the Company shall not be
             required to register or qualify Registrable Securities in any state
             or province where such qualification or registration would place an
             undue burden on the Company or which would require that the Company
               consent or agree to restrictions, covenants, or qualifications
               which the Company deems unacceptable;

                    (v)  cause all registrable Securities covered by such
               registration statement to be registered with or approved by such
               other federal, provincial, or state governmental agencies or
               authorities as may be necessary in the opinion of counsel to the
               Company and counsel to the underwriters to enable the seller or
               sellers thereof to consummate the disposition of such Registrable
               Securities;

                    (vi) furnish at the effective date of such registration
               statement and, if applicable, the date of the closing under the
               underwriting agreement, to each seller of Registrable Securities,
             and each such seller's underwriters, a signed counterpart of (x) an
             opinion of counsel for the Company, dated the effective date of
               such registration statement and (y) a "comfort" letter signed by
               the independent public  accountants who have certified the
               Company's financial statements included or incorporated by
               reference in such registration statement, covering substantially
               the same matters with respect to such registration statement (and
               the prospectus included therein) and, in the case of the
               accountants' comfort letter, with respect to events subsequent to
               the date of such financial statements, as are customarily covered
             in opinions of issuer's counsel and in accountants' comfort letters
               delivered to the underwriters in underwritten public offerings of
               securities and, in the case of the accountants' comfort letter,
               such other financial matters, and, in the case of the legal
               opinion, such other legal matters, as the sellers of the
               Registrable Securities covered by such registration statement, or
               the underwriters, may reasonably request;

                  (vii)     notify each seller of Registrable Securities covered
               by such registration statement at any time when a prospectus
               relating thereto is required to be delivered under the Securities
               Act or the Applicable Canadian Securities Laws, upon discovery
             that, or upon the happening of any event as a result of which, the 
               prospectus included in such registration statement, as then in
             effect, includes an untrue statement of a material fact or omits to
             state any material fact required to be stated therein or necessary
               to make the statements therein no misleading, in the light of the
             circumstances under which they were made, and at the request of any
             such seller promptly prepare and furnish to it a reasonable number
               of copies of supplement to or an amendment of such prospectus as
             may be necessary so that, thereafter delivered to the purchasers of
               such securities, such prospectus shall not include an untrue
               statement of a material fact or omit to state a material fact
               required to be stated therein or necessary to make the statements
               therein not misleading in the light of the circumstances under
               which they were made;

                    (viii)    otherwise comply with all applicable rules and
               regulations of the Commission and the Canadian Securities

             eighteen months, beginning with the first full calendar month after
             the effective date of such registration  statement, which earnings
               statement shall satisfy the provision of Section 11(a) of the
               Securities Act an Rule 158 promulgated thereunder, and promptly
             furnish to each such seller of Registrable SECURITIES as a copy of
               any amendment or supplement to such registration statement or
               prospectus;

                    (ix) keep each Selling Holder and each Requesting Holder
               advised in writing as to the initiation and progress of any

               be; 

                    (x)  provide and cause to be maintained a transfer agent and
               registrar (which, in each case, may be the Company) for all
             Registrable Securities covered by such registration statement from
               and after a date not later than the effective date of such
               registration; and

                    (xi) list all Registrable Securities covered by such
               registration statement on any securities exchange on which
               Registrable Securities of the same class and, if applicable,
               series, covered by such registration statement are then listed or
             on the Nasdaq Stock Market ("Nasdaq") if the Registrable Securities
               covered by such registration statement from and after a date not
               later than the effective date of such registration; and

                    (xi) list all Registrable Securities covered by such
               registration statement on any securities exchange on which

               are reported on Nasdaq.

The Company may require each seller of Registrable Securities, as to which
any registration is being effected, to furnish the Company such information
regarding such seller and the distribution of such securities, as required by
laws or the Commission or the Canadian Securities regulators, or which the
Company's counsel otherwise deems appropriate.

          Each holder of Registrable Securities agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described
in subdivision (vii) of this Section  1.3, such holder will forthwith
discontinue such holder's disposition of Registrable Securities pursuant to

the prospectus relating to such Registrable Securities current at the time of
receipt of such notice.

               1.4  Underwritten Offerings.

                    (a)  Requested Underwritten Offerings.  If requested by the
underwriters for any underwritten offering by holders of Registrable
SECURITIES pursuant to a registration requested under Section 1.1, the
company will use all reasonable efforts to enter into an underwriting
agreement with such underwriters for such offering, such agreement to be
reasonably satisfactory in substance and form to each such holder and the
underwriters and to contain such representations and warranties by the
Company and such other terms as are generally prevailing in agreements of
that type, including, without limitation, indemnities to the  effect and to
the extent provided in Section 1.7.  The holders of the Registrable
Securities proposed to be sold by such underwriters will reasonably cooperate
with the Company in the negotiation of the underwriting agreement.  Such
holders of Registrable Securities to be sold by such underwriters shall be
parties to such underwriting agreement and may, at their option, require that
any or all of the representations and warranties by, and the other agreements
on the part of, the Company to and for the benefit of such underwriters shall
also be made to and for the benefit of such holders of Registrable Securities
and that any or all of the conditions precedent to the obligations of such
holders of Registrable Securities.  Any such holders of Registrable
Securities shall not be required to make any representations or warranties to
or agreements with the Company or the underwriters other than
representations, warranties or agreements regarding such holder, such
holder's registrable Securities and such holder's intended method of
distribution or any other representations required by applicable law.

                    (b)  Incidental Underwritten Offerings.  If the Company
proposes to register any of its securities under the Securities Act or the
Applicable Canadian Securities Laws as contemplated by Section 1.2 and such
securities are to be distributed by or through one or more underwriters, the
Company will, if requested by and Requesting Holder of Registrable
Securities, use reasonable efforts to arrange for such underwriters to
include all the Registrable Securities to be offered and sold by such
Requesting Holder among the securities of the Company to be distributed by
such underwriters.  The holders of Registrable Securities to be  distributed
by such underwriters shall be parties to the underwriting agreement between
the Company and such underwriters and may, at their option, require that any
or all of the representations and warranties by, and the other agreements on
the part of, the Company to an for the benefit of such underwriters shall
also be made to and for the benefit of such holders of Registrable Securities
and that any or all of the conditions precedent to the obligations of such
holders of Registrable Securities.  Any such Requesting Holder of Registrable
Securities shall not be required to make any representations or warranties or
agreements regarding such Requesting Holder, such Requesting Holder's
Registrable Securities and such Requesting Holder's intended method of
distribution or any other representations required by applicable law.

             1.5  Preparation; Reasonable Investigation.  In connection with the
preparation and filing of each registration statement under the Securities
Act or the Applicable Canadian Securities Laws pursuant to this agreement,
the Company (i) shall give the holders of Registrable Securities registered
under such registration statement, their underwriters, if any, and their
respective counsel and accountants the reasonable opportunity to participate
in the preparation of such registration statement, each prospectus included
therein or filed with the Commission or the Canadian Securities Regulators,
and each amendment thereof or supplement thereto, and (ii) shall promptly
notify the registered holders of Registrable Securities and their counsel of
any stop order issued or threatened by the commission or any Canadian
Securities Regulators and take  all reasonable actions required to prevent
the entry of such stop order or to remove it if entered.

               1.6  Qualification to Obligations under Registration Covenants. 
The Company shall be entitled to postpone for a reasonable period of time
(but not exceeding 120 days) the filing of any registration statement
otherwise required to be prepared and filed by it pursuant to Section 1.1 if
(i) the Company determines, in its reasonable judgment, that such
registration and offering would interfere with any financing, acquisition,
corporate reorganization or other material transaction involving the Company
or any of its affiliates or (ii) the Company is in possession of information
concerning it or its business and affairs, the public disclosure of which
wold have a material adverse effect on the Company and which the Company has
determined it is not legally obligated to disclose, and the Company promptly
gives the holders of Registrable Securities requesting registration thereof
pursuant to Section 1.1 written notice of such determination, containing a
general statement of the reasons for such postponement and an approximation
of the anticipated delay.  If the Company shall so postpone the filing of a
registration statement, Initiating Holders requesting registration thereof
pursuant to Section 1.1 shall have the right to withdraw the request for
registration by giving written notice to the Company within 30 days after
receipt of the notice of postponement and, in the event of such withdrawal,
such request shall not be counted for purposes of the requests for
registration to which holders of Registrable Securities are entitled pursuant
to Section 1.1 hereof.

               1.7  Indemnification.

                    (a)  Indemnification by the Company.  The Company will, and
hereby does, indemnify and hold harmless, in the case of any registration
statement filed pursuant to Section 1.1 or 1.2, each seller of any
Registrable Securities covered by such registration statement and each other
Person who participates as an underwriter in the offering or sale of such
securities and each other Person, if any, who controls such seller or any
such underwriter within the meaning of the Securities Act or the Applicable
Canadian Securities Laws, and their respective directors, officers, partners,
employees and affiliates against any losses, claims damages or liabilities,
joint or several, to which such seller or underwriter or any such director,
officer, partner, employee, affiliate or controlling person may become
subject under the Securities Act or the Applicable Canadian Securities Laws
or otherwise, including, without limitation, the reasonable fees and expenses
of legal counsel, insofar as such losses, claims, damages or liabilities (or
actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in any registration statement under
which such securities were registered under the Securities Act or the
Applicable Canadian Securities Laws, any preliminary prospectus, final
prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the
statements therein in light of the circumstances in which they were made not
misleading, and the Company will reimburse such seller or underwriter and
each such director, officer, partner, employee, affiliate and controlling
Person for any legal or any other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, liability,
action or proceeding; provided, that the Company shall not be liable in any
such case to the extent that any such loss, claim, damage, liability (or
action or proceeding in respect thereof) or expense arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in such registration statement, any such preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company through an instrument duly executed by or on behalf of such seller or
underwriter, as the case may be, specifically stating that it is for use in
the preparation thereof.  Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of such seller or
any such director, officer, employee, affiliate, partner or controlling
person and shall survive the transfer of such securities by such seller.

                    (b)  Indemnification by the Sellers.  As a condition to
including any Registrable Securities in any registration statement, the
Company shall have received an undertaking satisfactory to it from the
prospective seller of such Registrable Securities, to indemnify and hold
harmless the Company, and each director of the Company, each officer of the
Company and each other Person, if any, who participates as an underwriter in
the offering or sale of such securities and each other Person who controls
the Company or any such underwriter within the meaning of the Securities Act
or the Applicable Canadian Securities Laws, and their respective directors,
officers, partners, employees and affiliates, against any losses, claims,
damages or liabilities, joint or several, to which such person may become
subject under the Securities Act or the Applicable Canadian Securities Laws
or otherwise, including, without limitation, the reasonable fees and expenses
of legal counsel, insofar as such losses, claims, damages or liabilities (or
actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in any registration statement under
which such securities were registered under the Securities Act or the
Applicable Canadian Securities Laws, any preliminary prospectus, final
prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the
statements therein in light of the circumstances in which they were made not
misleading, and to reimburse such person for any legal or any other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, liability, action or proceeding; but only to the extent
that any such loss, claim, damage, liability (or action or proceeding in
respect thereof) or expense arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement, any such preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement in reliance upon and
in conformity with written information furnished to the Company through an
instrument duly executed by or on behalf of such seller, specifically stating
that it is for use in the preparation thereof; provided, however, that the
liability of such indemnifying party under this Section 1.7(b) shall be
limited to the amount of proceeds received by such indemnifying party in the
offering giving rise to such liability.  Such indemnity shall remain in full
force and effect, regardless of any investigation made by or on behalf of the
Company or any such director, officer or controlling person and shall survive
the transfer of such securities by such seller.

                  (c)  Notices of Claims, etc.  Within ten days of receipt by an
indemnified party of notice of the commencement of any action or proceeding
involving a claim referred to in the preceding subdivisions of this Section
1.7, such indemnified party will, if a claim in respect thereof is to be made
against an indemnifying party, give written notice to the latter of the
commencement of such action; provided, however, that the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under the preceding subdivisions of
this Section 1.7, except to the extent that the indemnifying party is
actually prejudiced by such failure to give notice.  In case any such action
is brought against an indemnified party the indemnifying party shall be
entitled to participate in and to assume the defense thereof, jointly with
any other indemnifying party similarly notified to the extent that it may
wish, with counsel reasonably satisfactory to such indemnified party, and
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not
be liable to such indemnified party for any legal or other expenses
subsequently incurred by the latter in connection with the defense thereof,
provided, however, that if the indemnified party reasonably believes it is
advisable for it to be represented by separate counsel because there exists
a conflict of interest between its interests and those of the indemnifying
party with respect to such claim, or there exist defenses available to such
indemnified party which may not be available to the indemnifying party, or if
the indemnifying party shall fail to assume responsibility for such defense,
the indemnified party may retain counsel satisfactory to it and the
indemnifying party shall pay all reasonable fees and expenses of such
counsel.  No indemnifying party shall be liable for any settlement of any
action  proceeding effected without its written consent.  No indemnifying
party shall, without the consent of the indemnified party, consent to entry
of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation or which requires action by the indemnified party.

                    (d)  Contribution.  If the indemnification provided for in
this Section 1.7 shall for any reason be held by a court to be unavailable to
an indemnified party under subparagraph (a) or (b) hereof in respect of any
loss, claim, damage or liability, or any action in respect thereof, then, in
lieu of the amount paid or payable under subparagraph (a) or (b) hereof, the
indemnified party and the indemnifying party under subparagraph (a) or (b)
hereof shall contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in
connection with investigating the same), (i) in such proportion as is
appropriate to reflect the relative fault of the Company and the prospective
sellers of Registrable Securities covered by the registration statement which
resulted in such loss, claim damage or liability, or action in respect
thereof, with respect to the statements or omissions which resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as
any other relevant equitable considerations or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as shall be appropriate to reflect the relative benefits received
by the Company and such prospective sellers from the offering of the
securities covered by such registration statement.  No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.  Such prospective sellers'
obligations to contribute as provided in this subparagraph (d) are several in
proportion to the relative value of their respective Registrable Securities
covered by such registration statement and not joint.  In addition, no Person
shall be obligated to contribute hereunder any amounts in payment for any
settlement of any action or claim effected without such Person's consent,
which consent shall not be unreasonably withheld or delayed.

                  (e)  Other Indemnification.  Indemnification and contribution
similar to that specified in the preceding subdivisions of this Section 1.7
(with appropriate modifications) shall be given by the Company and each
seller of Registrable Securities with respect to any required registration or
other qualification of securities under any federal or state law or
provincial law or any regulation of any governmental authority other than the
Securities Act or the Applicable Canadian Securities Laws.

                    (f)  Indemnification Payments.  The indemnification and
contribution required by this Section 1.7 shall be made by periodic payments
of the amount thereof during the course of the investigation or defense, as
and when bills are received or expense, loss, damage or liability is
incurred.

OF EXEMPTION FROM THE REGISTRATION OR QUALIFICATION PROVISIONS OF FEDERAL AND
STATE SECURITIES LAWS BASED, IN PART, ON AN INVESTMENT REPRESENTATION OF THE
PART OF THE PURCHASER THEREOF. THESE SECURITIES MAY NOT BE SOLD, PLEDGED,

     FLOTEK INDUSTRIES INC. (the "Company"), a corporation organized under

10, the subscription form attached hereto having then been duly executed by
the Holder, accompanied by cash, certified check or bank draft in payment of
the purchase price for the number of shares of the Warrant Stock specified in
the subscription form, or as otherwise provided in this Warrant prior to 4:00
p.m., local Vancouver time, on October 16, 1998.
  
     (b)  This Warrant may be exercised in whole or in part so long as any
exercise in part hereof would not involve the issuance of fractional shares
of Warrant Stock. If exercised in part, the Company shall deliver to the
Holder a new Warrant, identical in form, in the name of the Holder,
evidencing the right to purchase the number of shares of Warrant Stock as to
which this Warrant has not been exercised, which new Warrant shall be signed
by the Chairman and CEO or the President and the Secretary or the Assistant
Secretary of the Company. The term Warrant as used herein shall include any
subsequent Warrant issued as provided herein.  

     (c)  No fractional share or scrip representing fractional shares shall
be given upon the exercise of this Warrant. The Company shall pay cash in
lieu of fractions with respect to the Warrants based upon the Warrant Price
at the time of exercise of this Warrant.  

     (d)  In the event of any exercise of the rights represented by this
Warrant, a certificate or certificates for the Warrant Stock so purchased,
registered in the name of the Holder, shall be delivered to the Holder within
a reasonable time after such rights shall have been so exercised. The person
or entity in whose name any certificate for the Warrant Stock is issued upon
exercise of the rights represented by this Warrant shall for all purposes be
deemed to have become the holder of record of such shares immediately prior
to the close of business on the date on which the Warrant was surrendered and
payment of the Warrant Price and any applicable taxes was made, irrespective
of the date of delivery of such certificate, except that, if the date of such
surrender and payment is a date when the stock transfer books of the Company
are closed, such person shall be deemed to have become the holder of such
shares at the opening of business on the next succeeding date on which the
stock transfer books are open.  

2.   Disposition of Warrant Stock and Warrant.  

     (a)  By the acceptance of this Warrant, the Holder hereby acknowledges
and covenants that this Warrant and any Warrant Stock purchased pursuant
thereto are and will be held for investment and not for distribution;
provided that:  

          (i)  the Warrant and/or Warrant Stock may not be transferred by the
               Holder, (A) unless an exemption is available under the
               Securities Act of 1933, as amended, and the rules and
               regulations promulgated by the Securities and Exchange
               Commission thereunder (collectively the "Act"), and to a
               person who, in the opinion of counsel to the Company, is a
               person to whom the Warrant and/or Warrant Stock may be
               transferred legally without registration and without the
               delivery of a current prospectus under the Act with respect
               thereto and then only against receipt of (x) an agreement of
               such person to comply with the provisions of this Section 2
               with respect to any resale or other disposition of such
               securities and (y) an agreement by such person that he is
               acquiring such securities for investment and not for
               distribution except in compliance with the Act; or (B) except
               to a person upon delivery of a prospectus relating to the
               Warrant and/or Warrant Stock then meeting the requirements of
               the Act;  

          (ii) the Warrant Stock shall be issued upon exercise of this
               Warrant only in compliance with the Act;  

          (iii)     so long as the Warrant Stock is listed on the Vancouver
                    Stock Exchange, the Warrant may not be transferred
                    without the consent of the Vancouver Stock Exchange,
                    except that the initial Holder, which is a Texas limited
                    partnership, may make an in kind distribution of the
                    Warrant to its partners in proportion to their
                    partnership interests, provided that such partners take
                    the Warrant subject to all the transfer restrictions set
                    forth herein; and  

          (iv) this Warrant and the Warrant Stock may be pledged to a lender
               to secure the debt of the Holder.  

     (b)  If, at the time of issuance of the shares issuable upon exercise of
this Warrant, no registration statement is in effect with respect to such
shares under applicable provisions of the Act, the Company may at its
election require that the Holder provide the Company with written
reconfirmation of the Holder's investment intent and that any stock
certificate delivered to the Holder of a surrendered Warrant shall bear
legends reading substantially as follows:  
 
     "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN AND WILL NOT BE
     REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS
     AMENDED (THE "1933 ACT").  THE HOLDER HEREOF, BY PURCHASING SUCH
     SECURITIES, AGREES FOR THE BENEFIT OF THE ISSUER THAT SUCH SHARES
     MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY (A) TO
     THE ISSUER, (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE
     904 OF REGULATION S UNDER THE 1933 ACT AND IN ACCORDANCE WITH
     APPLICABLE STATE SECURITIES LAW, (C) PURSUANT TO THE EXEMPTION FROM
     REGISTRATION REQUIREMENTS UNDER THE 1933 ACT PROVIDED BY RULE 144
     THEREUNDER, IF AVAILABLE, AND IN ACCORDANCE WITH APPLICABLE STATE
     SECURITIES LAWS, OR (D) IN A TRANSACTION THAT DOES NOT REQUIRE
     REGISTRATION UNDER THE 1933 ACT OR ANY APPLICABLE STATE LAWS AND
     REGULATIONS GOVERNING THE OFFER AND SALE OF SECURITIES, AND THE
     HOLDER HAS, PRIOR TO SUCH SALE, FURNISHED TO THE ISSUER AN OPINION
     OF COUNSEL, OF RECOGNIZED STANDING, OR OTHER EVIDENCE OF EXEMPTION,
     REASONABLY SATISFACTORY TO THE ISSUER.  DELIVERY OF THIS
     CERTIFICATE MAY NOT CONSTITUTE "GOOD DELIVERY" IN SETTLEMENT OF
     TRANSACTIONS ON STOCK EXCHANGES IN CANADA.  A NEW CERTIFICATE,
     BEARING NO LEGEND, DELIVERY OF WHICH WILL CONSTITUTE "GOOD
     DELIVERY", MAY BE OBTAINED FROM THE REGISTRAR AND TRANSFER AGENT OF
     THE ISSUER UPON DELIVERY OF THIS CERTIFICATE AND A DULY EXECUTED
     DECLARATION, AN A FORM SATISFACTORY TO THE ISSUER AND ITS REGISTRAR
     AND TRANSFER AGENT, TO THE EFFECT THAT THE SALE OF THE SECURITIES
     REPRESENTED HEREBY IS BEING MADE IN COMPLIANCE WITH RULE 904 OF
     REGULATION S UNDER THE 1933 ACT AND IN ACCORDANCE WITH APPLICABLE
     STATE SECURITIES LAWS."
 
In addition, so long as the foregoing legend may remain on any stock
certificate delivered to the Holder, the Company may maintain appropriate
"stop transfer" orders with respect to such certificates and the shares
represented thereby on its books and records and with those to whom it may
delegate registrar and transfer functions.

     (c)  If this Warrant is exercised prior to 4:00 p.m. local Vancouver
time on October 16, 1998, any stock certificate delivered to the Holder of a
surrendered Warrant shall bear a legend reading substantially as follows:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
     HOLD PERIOD AND MAY NOT BE TRADED IN BRITISH COLUMBIA UNTIL THE
     EXPIRY OF THE HOLD PERIOD, EXCEPT AS PERMITTED BY THE SECURITIES
     ACT (BRITISH COLUMBIA) AND RULES MADE UNDER THE ACT.  THE HOLD
     PERIOD EXPIRES AT 12:00 A.M. (MIDNIGHT) ON October 16, 1998."

3.   Reservation of Shares.
 
     The Company hereby agrees that at all times there shall be reserved for
issuance upon the exercise of this Warrant such number of shares of its
Common Stock as shall be required for issuance upon exercise of this Warrant
and that the par value of such shares will at all times be less than or equal
to the applicable Warrant Price. The Company further agrees that all shares
which may be issued upon the exercise of the rights represented by this
Warrant will, upon issuance, be validly issued, fully paid and non-
assessable, free from all taxes, liens and charges with respect to the
issuance thereof other than taxes, if any, in respect of any transfer
occurring contemporaneously with such issuance and other than transfer
restrictions imposed by federal and state securities laws.

4.   Capital Adjustments.
 
     This Warrant is subject to the following further provisions:
 
     (a)  Recapitalization. Reclassification and Succession. If any
recapitalization of the Company or reclassification of its Common Stock or
any merger or consolidation of the Company into or with a corporation or
other business entity, or the sale or transfer of all or substantially all of
the Company's assets or of any successor corporation's assets to any other
corporation or business entity (any such corporation or other business entity
being included within the meaning of the term "successor corporation") shall
be effected, at any time while this Warrant remains outstanding and
unexpired, then, as a condition of such recapitalization, reclassification,
merger, consolidation, sale or transfer, lawful and adequate provision shall
be made whereby the Holder of this Warrant thereafter shall have the right to
receive upon the exercise hereof as provided in Section 1 and in lieu of the
shares of Common Stock immediately theretofore issuable upon the exercise of
this Warrant, such shares of capital stock, securities or other property as
may be issued or payable with respect to or in exchange for a number of
outstanding shares of Common Stock equal to the number of shares of Common
Stock immediately theretofore issuable upon the exercise of this Warrant had
such recapitalization, reclassification, merger, consolidation, sale or
transfer not taken place, and in each such case, the terms of this Warrant
shall be applicable to the shares of stock or other securities or property
receivable upon the exercise of this Warrant after such consummation.

     (b)  Subdivision or Combination of Shares. If the Company at any time
while this Warrant remains outstanding and unexpired shall subdivide or
combine its Common Stock, the number of shares of Warrant Stock purchasable
upon exercise of this Warrant shall be proportionately adjusted.

     (c)  Certain Dividends and Distributions. If the Company at any time
while this Warrant is outstanding and unexpired shall take a record of the
holders of its Common Stock for the purpose of entitling them to receive a
dividend payable in, or other distribution of, Common Stock, then the number
of shares of Warrant Stock purchasable upon exercise of this Warrant shall be
adjusted to that number determined by multiplying the number of shares of
Warrant Stock so purchasable immediately prior to such record date by a
fraction (i) the numerator of which shall be the sum of (A) the total number
of outstanding shares of Common Stock immediately prior to such record date
and (B) the total number of shares of Common Stock issuable pursuant to such
dividend or distribution, and (ii) the denominator of which shall be the
total number of shares of Common Stock outstanding immediately prior to such
record date.  

     (d)  Corresponding Warrant Price Adjustment. Whenever the number of
shares of Warrant Stock purchasable upon the exercise of the rights granted
to the Holder herein is increased or decreased as provided in Section 4 (b)
or (c), the Warrant Price payable for the exercise of such rights shall be
adjusted by multiplying such Warrant Price immediately prior to such
adjustment by a fraction, of which the numerator shall be the number of
shares of Warrant Stock purchasable upon the exercise of such rights
immediately prior to such adjustment, and of which the denominator shall be
the number of shares of Warrant Stock purchasable immediately thereafter.  

     (e)  Certain Shares Excluded. The number of shares of Common Stock
outstanding at any given time for purposes of the adjustments set forth in
this Section 4 shall exclude any shares then directly or indirectly held in
the treasury of the Company.

     (f)  Deferral and Cumulation of De Minimis Adjustments. The Company
shall not be required to make any adjustment of the Warrant Price pursuant to
this Section 4 if the amount of such adjustment would be less than one
percent (1%) of the Warrant Price in effect immediately before the event that
would otherwise have given rise to such adjustment. In such case, however,
any adjustment that would otherwise have been required to be made shall be
made at the time of and together with the next subsequent adjustment which,
together with any adjustment or adjustments so carried forward, shall amount
to not less than one percent (1%) of the Warrant Price in effect immediately
before the event giving rise to such next subsequent adjustment.  

     (g)  Duration of Adjusted Warrant Price. Following each computation or
readjustment of an adjusted Warrant Price as provided in this Section 4, the
new adjusted Warrant Price shall remain in effect until a further computation
or readjustment thereof is required.  

5.   Notices to Holders. 

     (a)  Notice of Record Date. In case:  

          (i)  the Company shall take a record of the holders of its Common
               Stock (or other stock or securities at the time receivable
               upon the exercisable of this Warrant) for the purpose of
               entitling them to receive any dividend (other than a cash
               dividend payable out of earned surplus of the Company) or
               other distribution, or any right to subscribe for or purchase
               any shares of stock of any class or any other securities, or
               to receive any other right; or  

          (ii) of any capital reorganization of the Company, any
               reclassification of the capital stock of the Company, any
               consolidation with or merger of the Company into another
               corporation, or any conveyance of all or substantially all of
               the assets of the to another corporation; or

          (iii)of any voluntary dissolution, liquidation or winding-up of the 
               Company;  

then, and in each such case, the Company will mail or cause to be mailed to
the Holder hereof at the time outstanding a notice specifying, as the case
may be, (i) the date on which a record is to be taken for the purpose of such
dividend, distribution or right, and stating the amount and character of such
dividend, distribution or right, or (ii) the date on which such
reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up is to take place, and the time, if
any, is to be fixed, as of which the holders of record of Common Stock (or
such stock or securities at the time receivable upon the exercise of this
Warrant) shall be entitled to exchange their shares of Common Stock (or such
other stock or securities) for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up. Such notice shall be mailed at least
30 days prior to the record date therein specified, or if no record date
shall have been specified therein, at least 30 days prior to such other
specified date.  

     (b)  Notice of Adjustments. Whenever any Warrant Price shall be
adjusted, pursuant to Section 4 hereof, the Company shall promptly make a
certificate signed by its Chairman, its CEO, its President or a Vice
President and by its Treasurer or Assistant Treasurer or its Secretary or
Assistant Secretary, setting forth in reasonable detail, the event requiring
the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated and the Warrant Price after giving effect to such
adjustment, and shall promptly cause copies of such certificates to be mailed
(by first class mail, postage prepaid) to the Holder of this Warrant.  

6.   Loss, Theft, Destruction or Mutilation.  

     Upon receipt by the Company of evidence satisfactory to it, in the
exercise of its reasonable discretion, of the ownership and the loss, theft,
destruction or mutilation of this Warrant and, in the case of loss, theft or
destruction, of indemnity reasonably satisfactory to the Company and, in the
case of mutilation, upon surrender and cancellation thereof, the Company will
execute and deliver in lieu thereof, without expense to the Holder, a new
Warrant of like tenor dated the date hereof. 

7.   Warrant Holder Not a Stockholder.  

     The Holder of this Warrant, as such, shall not be entitled by reason of
this Warrant to any rights whatsoever as a stockholder of the Company.  

8.   Transfer; Register.  

     Subject to the provisions of Section 2 above, this Warrant is
transferable in the same manner and with the same effect as in the case of a
negotiable instrument payable to a specified person. Pursuant to Section 6.4
of the Securities Purchase Agreement, the Warrants shall be issued in
registered form only and the Company shall keep a register (the "Warrant
Register") in which provisions shall be made for the registration of the
Warrants and the registration of transfers thereof. Such Register shall be
kept at the principal office of the Company and the Company is hereby
appointed the "Warrant Registrar" for the purpose of registering the Warrants
and transfers of the Warrants. Subject to compliance with the provisions of
Section 2 hereof by a transferee, upon surrender for registration of transfer
of any Warrant at the principal office of the Company, the Company shall
execute and deliver, in the name of the designated transferee, a new Warrant.
The Company shall treat the individual or entity in whose name each Warrant
is registered on the Warrant Register as the sole and absolute owner thereof,
notwithstanding any contrary notice.  

9.   Registration Rights.  

     The Holder shall have certain registration rights with respect to the
Warrant Shares, all as set forth in a Registration Rights Agreement of even
date herewith among the Company, the Holder and certain other Holders.  

10.  Notices.  

     Any notice required or contemplated by this Warrant shall be deemed to
have been duly given if transmitted by registered or certified mail, return
receipt requested, to the Company at 7030 Empire Central Drive, Houston,
Texas 77040, Attention: President, or to the Holder at the name and address
set forth in the Warrant Register maintained by the Company.  

11.  Choice of Law.  

     This Warrant shall be governed by the laws of the State of Texas
(exclusive of any such laws that pertain to conflicts of laws).

     IN WITNESS WHEREOF, the undersigned has duly signed this Warrant and
Pacific Corporate Trust Company has caused this Warrant Certificate to be
