REGISTRATION RIGHTS AGREEMENT, dated as of April 30, 2000, between
Flotek Industries Inc, an Alberta corporation (the "Company"), and each of the
parties identified on Schedule A hereto (the "Principal Stockholders").
Capitalized terms used herein but not otherwise defined shall have the
meanings given them in Section 2. All Dollar amounts referred to herein are US
Dollars, unless otherwise noted.
1. 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 the 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 purpose 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 a "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 to 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 to 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.
<PAGE>
(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) Selection 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 affect 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 of 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;
<PAGE>
(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) the Principal Shareholders collectively hold fewer
than 100,000 shares of Registrable Securities, or (B) 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 any 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 of 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 included 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.
3
<PAGE>
(c) Expenses. The Company will pay all Registration
--------

1.2.

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

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

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 sellers to consummate the
disposition in such jurisdictions 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 a foreign
corporation in any jurisdiction wherein it would not but for the
requirements of this subdivision (iv) be obligated to be so
4
<PAGE>
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

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 not 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
a supplement to or an amendment of such prospectus as may be
necessary so that, as 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;
5
<PAGE>
(viii) otherwise comply with all applicable rules and
regulations of the Commission and the Canadian Securities
Regulators, and, if required, make available to its security
holders, as soon as reasonably practicable, an earnings statement
covering the period of at least twelve months, but not more than
eighteen months, beginning with the first full calendar month after
the effective date of such registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the
Securities Act and Rule 158 promulgated thereunder, and promptly
furnish to each such seller of Registrable Securities 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
registration under Section 1.1 or 1.2 hereunder, as the case may 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

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
law 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
registration statement relating to such Registrable Securities until such
holder's receipt of the copies of the supplemented or amended prospectus

Company, will deliver to the Company (at the Company's expense) all copies,
other than permanent file copies, then in such holder's possession of the
prospectus relating to such Registrable Securities current at the time of
receipt of such notice.

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

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 would 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

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
8
<PAGE>
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
9
<PAGE>
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 or 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
