Warrant No. 2                                                      Warrant Stock

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, AND HAVE BEEN ISSUED PURSUANT TO A CLAIM 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,
HYPOTHECATED, DONATED OR OTHERWISE TRANSFERRED WITHOUT COMPLIANCE WITH THE
REGISTRATION OR QUALIFICATION PROVISIONS OF APPLICABLE FEDERAL AND STATE
SECURITIES LAWS OR APPLICABLE EXEMPTIONS THEREFROM.


       FLOTEK INDUSTRIES INC. (the "Company"), a corporation organized under
the laws of the Province of Alberta, Canada, for value received, hereby agrees
to sell upon the terms and on the conditions hereinafter set forth to Marlin
Investors, L.L.C., the registered holder hereof (the "Holder"), having an
address set forth in the Warrant Register maintained by the Company, under the
terms as hereinafter set forth, Nine Million Three Hundred Thirty-Three
Thousand Three Hundred Thirty-Four (9,333,334) fully paid and non-assessable
shares of the Company's Common Stock, no par value (the "Warrant Stock"), at a
purchase price per share of Fifteen Canadian Cents (CDN $0.15) at any time
prior to 4:00 p.m., Vancouver Time, on September 14, 1998, and at a purchase
price per share of Seventeen Canadian Cents (CDN $0.17) at any time thereafter,
but no later than 4:00 p.m., Vancouver Time, on the Expiration Date (as
hereinafter defined) (as adjusted as provided herein, the "Warrant Price")
pursuant to this Warrant (the "Warrant").  The number of shares of Warrant
Stock to be so issued and the Warrant Price are subject to adjustment as
hereinafter set forth.  The term "Common Stock" shall mean, when used herein,
unless the context otherwise requires, the stock and other securities and
property at the time receivable upon the exercise of this Warrant.


1.     Exercise of Warrant.

       (a)    The Holder may exercise this Warrant according to its terms by
surrendering this Warrant to the Company at the address set forth in Section
10, the subscription form attached hereto having then been duly executed by the
Holder, accompanied by cash, certified check or
   2
                                    - 2 -





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 the Expiration Date.
The Expiration Date shall be September 14, 1999.

       (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
   3
                                     - 3 -




                               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 Holder, which is
                               a Delaware limited liability company, may make an
                               in kind distribution of the Warrant to its
                               members in proportion to their membership
                               interests, provided that such members 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 THE 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





   4
                                     - 4 -




       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, IN 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 September 14, 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 SEPTEMBER 14, 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:




   5
                                     - 5 -




       (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.




   6
                                     - 6 -




       (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 Company 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,





   7
                                     - 7 -




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.  This Warrant 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
this Warrant 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 and compliance with the
provisions of Section 2 hereof, if applicable, 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.
