            course of business, consistent with past practices, are valid and
            binding obligations of the account debtors, and, subject to the

             hundred and eighty (180) days at the aggregate recorded amounts
             thereof (subject to no defense, counterclaim or set-off).

        vi.  Except as set forth in Schedule 4.7, there are no liabilities 
             either accrued, absolute or contingent, including, without
             limitation, liabilities under any applicable environmental, safety

             wadeco or the subsidiaries of any kind whatsoever, in respect of
             which the purchaser may become liable on or after the consummation
             of the transactions contemplated by this agreement, the other
             transaction documents or the reorganization documents.

        vii. Except as set forth in Schedule 4.7, each of the December Financial
             Statements and the Closing Financial Statements were prepared in
             accordance with the Wadeco Financial Statements for the respective
             periods, on a consistent basis, and present fairly, in all material
             respects, the financial position of Wadeco and the Subsidiaries and
             the results of their operations in accordance with GAAP.

H.     TAXES

        i.   Except as set forth in Schedule 4.8, Wadeco and the Subsidiaries
             have, at the prescribed times, filed all Tax Returns that are
             required to be filed by them with any Governmental Authority, made
             and remitted all required deductions or withholdings at source, and
             have paid all Taxes due pursuant to the Tax Returns or any
             assessments received by them or otherwise required to be paid,
             except Taxes being contested in good faith by appropriate
             proceedings and for which adequate reserves or other provisions are
             maintained. All Tax Returns are true, complete and correct in all
             material respects, and properly reflect, and do not in any respect
             understate, the taxable income or the liability for Taxes of Wadeco
             and/or the Subsidiaries, as the case may be, in the relevant tax
             year or calendar year. Adequate provision has been made in the
             Wadeco Financial Statements for the year ended April 30, 1996 for
             all Taxes payable in respect of the business or assets of Wadeco
             and the Subsidiaries. Except as set forth in Schedule 4.8, no
             adjustment relating to such Tax Returns has been proposed formally
             or informally by any Governmental Authority and, no basis exists
             for any such adjustments involving a material amount of Taxes.

        ii.  Except as set forth in Schedule 4.8, Tax Returns of Wadeco and the
             Subsidiaries filed pursuant to the Income Tax Act (Canada) and any
             other applicable laws of Canada or the United States or any other
             applicable jurisdiction imposing taxes have been audited through
             the years ended as set forth in Schedule 4.8 and assessed through
             the years ended as set forth in Schedule 4.8, and such assessments,
             if any amounts were owing in respect thereof, have been provided
             for in the Closing Financial Statement. There is no basis for any
             adverse reassessment by any Governmental Authority for any year
             remaining open for reassessment. Neither Wadeco nor the
             Subsidiaries is a party to any claim, action, suit, inquiry,
             proceeding, investigation or audit by 

                                       22
<PAGE>
 
             any Governmental Authority and no claim has been asserted,
             threatened or proposed against either Wadeco or the Subsidiaries
             for assessment or collection of any Taxes other than those that
             have been properly reserved for in the Closing Financial
             Statements. The Company and the Subsidiaries have not executed or
             filed with Revenue Canada or any other Governmental Authority any
             agreement extending the period of assessment or collection of any
             Taxes.

       iii.  Without limiting the generality of the foregoing, Wadeco and the
             Subsidiaries are in absolute compliance, in all material respects,
             with all registration, timely reporting and remittance obligations
             in respect of all taxation legislation applicable to Wadeco and the
             Subsidiaries. All Taxes that Wadeco or the Subsidiaries are
             required to withhold or collect have been withheld or collected
             and, to the extent required, have been paid over to the proper
             Governmental Authority at the prescribed times.

       iv.   No portion of the real property or plant, structures, fixtures or
             improvements of Wadeco or the Subsidiaries is subject to any
             special assessment. There is no reason to know of any proposal for
             any such assessment.

Q.     INTELLECTUAL PROPERTY

       Schedule 4.17 contains an accurate and complete list of all Intellectual
Property.  In regard to such Intellectual Property, and except as set forth in
Schedule 4.17, the patents, trademarks and copyrights are valid, subsisting and
enforceable, and the patents, registered trademarks and registered copyrights
are duly recorded in the name of Wadeco and/or the Subsidiaries, as the case may
be, and can be recorded in the name or names of Wadeco and/or the Subsidiaries.
Except as set forth in Schedule 4.17, Wadeco and the Subsidiaries have, and
after the Closing will have, except as set forth in this Agreement, the sole and
exclusive ownership and right, free from any Liens, mortgages, security
interests, charges or encumbrances, to use the Intellectual Property and the
consummation of the transactions contemplated hereby will not alter or impair
any such rights.  Except as set forth in Schedule 4.17, within the last ten
years, no claims have been asserted by any entity or person with respect to, or
challenging or questioning, the ownership, validity, enforceability or use of
the Intellectual Property nor is there a valid basis for any such claim.  The
use or other exploitation of the Intellectual Property by Wadeco or the
Subsidiaries, as the case may be, does not infringe the rights of any other
entity or person.  No entity or person is infringing the rights of Wadeco or the
Subsidiaries with respect to the Intellectual Property.  Schedule 4.17 sets
forth a true and complete list of all license agreements between Wadeco and/or
the Subsidiaries, as the case may be, and third parties with respect to the use
of the Intellectual Property.  The Intellectual Property is used exclusively in
connection with the businesses of Wadeco and the Subsidiaries and is not used in
a manner likely to cause confusion in the marketplace.  All trade secrets of
Wadeco and the Subsidiaries are the unencumbered property of Wadeco and/or the
Subsidiaries, do not infringe upon the rights of any third party, were developed
by Wadeco and/or the Subsidiaries and their respective employees with
appropriate secrecy safeguards, are not generally known by others and have been
maintained by Wadeco and the Subsidiaries subject to secrecy safeguards.  There
are no persons or entities (other than the authorized agents of Wadeco and the
Subsidiaries) who have written copies of the formulae or any other written,
recorded or registered information relating to such trade secrets.  No third
party which is not duly authorized by Wadeco or the Subsidiaries, as the case
may be, is or has engaged in any activity which would constitute a
misappropriation or dissemination of any of the trade secrets of Wadeco or the
Subsidiaries or any other Intellectual Property.

or such claims exceed, in the aggregate, $250,000 (whereupon the indemnified
party shall be entitled to indemnification in full in respect of all such
indemnifiable Losses).  Furthermore, it is understood and agreed that (i) the

indemnifiable Losses in excess of $200,000.

C.     THIRD PARTY CLAIMS, NOTICE AND OPPORTUNITY TO SETTLE

       i.     Within 20 days after the receipt by the party entitled to 
              indemnity hereunder (the "Indemnified Party") of any claim or
              demand (including, but not limited to, notice of any action, suit
              or proceeding) by any third party against an Indemnified Party
              which gives rise to a right to indemnification for a Loss
              hereunder, the affected Indemnified Party shall give each party
              who may be obligated to provide indemnity hereunder (the
              "Indemnifying Party") written notice of such claim or demand;
              provided however, that the failure to give 

                                       39
<PAGE>
 
              such notice shall not relieve the Indemnifying Party of its
              obligations hereunder except to the extent that such failure is
              materially prejudicial to the Indemnifying Party.

       ii.    The Indemnifying Party shall have the right (without prejudice to 
              the right of any Indemnified Party to participate at its own
              expense through counsel of its own choosing), to defend against
              such claim or demand at its expense and through counsel of its own
              choosing (the choice of such counsel to be subject to the
              reasonable consent of the affected Indemnified Parties) and to
              control such defense if it gives written notice of its intention
              to do so within 15 days of the receipt of the notice referred to
              in Section 10.3(a) above. If the Indemnifying Party shall decline
              to assume the defense of such claim or demand, the affected
              Indemnified Parties shall have the right to assume control of such
              defense at the expense of the Indemnifying Party. The Indemnified
              Parties shall cooperate fully in the defense of such claim or
              demand and shall make available to the Indemnifying Party or its
              counsel all pertinent information under their control relating
              thereto. The Indemnifying Party agrees to cooperate with the
              Indemnified Parties in order to enable their counsel to
              participate in the defense and to deliver to the Indemnified
              Parties copies of all pleadings and other information within the
              Indemnifying Party's knowledge or possession reasonably requested
              by the Indemnified Parties that is relevant to the defense of any
              such claim or demand. The Indemnified Parties and their counsel
              shall maintain confidentiality with respect to all such
              information consistent with the conduct of a defense hereunder.

       iii.   The Indemnifying Party shall have the right to elect to settle 
              any such claim or demand for monetary damages only, subject to the
              consent of the affected Indemnified Parties; provided however, if
              the affected Indemnified Parties fail to give such consent within
              20 days of being requested to do so, the affected Indemnified
              Parties shall, at their expense, assume the defense of such claim
              or demand and regardless of the outcome for such matter, the
              Indemnifying Party's liability hereunder shall be limited to the
              amount of any such proposed settlement.

D.     NON-COMPETITION BREACH

       The parties hereto acknowledge and agree that no party shall have any
liability under the terms of this Agreement in respect of any non-competition
agreement or covenant given by any person, it being the intention of the parties
hereto that a person who has entered into such agreement or covenant shall
personally remain liable under such agreement or covenant given by him or her;
provided that nothing in this Agreement shall be construed as limiting the
liability of such person under such agreement or covenant given by him or her.

described in Section 10.1(c)(iii).  For greater certainty, the parties agree
that any indemnification payment made hereunder by Wadeco shall be included in
the $200,000 amount described in Section 10.1 relating to such claims.  Hokanson
and Russell acknowledge and agree that Wadeco shall have carriage of such
actions and the right to defend against such claims.  Hokanson and Russell

A.     AMENDMENT; WAIVER

       This Agreement may be amended only by a written instrument signed by the
parties hereto.  No failure to exercise and no delay in exercising, on the part
of any party, any right, remedy, power or privilege hereunder, shall operate as
a waiver thereof; nor shall any single or partial exercise of any right, remedy,
power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege.  The rights,
remedies, powers and privileges herein provided are cumulative and not exclusive
of any rights, remedies, powers and privileges provided by law.  The failure of
any party to insist upon a strict performance of any of the terms or provisions
of this Agreement, or to exercise any option, right or remedy herein contained,
shall not be construed as a waiver or as a relinquishment for the future of such
term, provision, option, right or remedy, but the same shall continue and remain
in full force and effect.  No waiver by any party of any term or provision of
this Agreement shall be deemed to have been made unless expressed in writing and
signed by such party.

B.     ASSIGNMENT

       No party hereto shall assign or transfer or permit the assignment or
transfer of this Agreement without the prior written consent of the other
parties; provided however, that nothing contained herein shall prevent the
transfer of this Agreement or any portion hereof by the Purchaser to an
Affiliate of the Purchaser, but no such assignment shall operate to relieve the
Purchaser from any obligation, liability, indemnity, warranty, covenant, promise
or agreement hereunder.

C.     SURVIVAL OF REPRESENTATIONS, WARRANTIES AND CERTAIN INDEMNITIES

       i.     Regardless of the investigations, if any, any party shall have

              contained herein shall be true as at the date hereof, and as at
              the date of Closing, and such representations and warranties shall
              survive the Closing and the benefit thereof to the other parties
              hereto shall continue for a period of five years from the date of

              which shall survive until the expiration of the time during which
              the minister of national revenue or any other governmental
              authority may assess tax, interest or penalties for the taxation
              year in question.

       ii.    Subject to Section 11.3(c) the indemnities provided for in 
              Sections 10.1 shall survive the Closing and shall thereafter apply
              in respect of Losses for which a state of facts giving rise to a
              bona fide claim for indemnity has arisen and written notice
              thereof has been provided to the Vendor by an Indemnified Party
              within five (5) years after the Closing; provided however, that
              any claim made by the Indemnified Party to the Indemnifying Party
              in writing on or before the date of expiry of such period which is
              not settled within that period, shall survive the end of the
              period until resolved.

       iii.   Notwithstanding any other provision of this Agreement, the 
              obligations of the Vendor and the Former Shareholders, to
              indemnify under Section 10.1(b), Section 10.1(c)(ii) and Section
              10.1(c)(iii) shall survive Closing indefinitely and the Vendor and
              the Former Shareholders agree not to raise any time limits for
              bringing an action to claim under such indemnities;

       iv.    The indemnities provided for in Section 10.2 shall survive the 
              Closing and shall thereafter apply in respect of Losses for which
              a state of facts giving rise to bona fide claim for indemnity has
              arisen and written notice thereof has been provided to the
              Purchaser by an Indemnified Party within five (5) years after the
              Closing; provided however, that any claim made by the Indemnified
              Party to the Indemnifying Party in writing on or before the date
              of expiry of such period which is not settled within that period,

(B)  there has been a change of control in the ownership of WADECO and its
     subsidiaries with all of the shares of WADECO including those previously
     beneficially owned, directly or indirectly, by Hokanson, having been
     acquired pursuant to a share purchase agreement dated May 31, 1996 (the

1.1  Non-Compete
     -----------

     Hokanson hereby covenants and agrees with WADECO that for a period of five

determine, he will not, directly or indirectly, enter into, sponsor, promote,

of any business within any province of Canada or any state in the United States
of America in which at the time of such determination WADECO or any of its
subsidiaries has carried on business, including the carrying on of marketing
activities, of a like nature to that of  providing centrifuges and other related
solids control equipment for the removal of aggregate from drilling mud and the
provision of chemical products for such operations and all business and function
necessarily incident thereto (the "Business") carried on by WADECO or any
subsidiary.  Hokanson and WADECO hereby declare that if any part of this

subsidiary, provided his involvement is solely as a passive investor.

any other business, firm, person, partnership or corporation, or otherwise
misuse any confidential information, data or trade secrets relating to WADECO or
any of its subsidiaries including, without limitation, information relating to
the operations of WADECO or any subsidiary of WADECO, their respective
purchasing, leasing, merchandising, promotion and compensation practices, their

     TUBOSCOPE VETCO INTERNATIONAL ACQUIRES WADECO OILFIELD SERVICES, LTD.


Houston, Texas, June 3, 1996, -- Tuboscope Vetco International Inc.
("Tuboscope") (NASDAQ: TUBO) today announced that it has acquired Wadeco
Oilfield Services, Ltd. ("Wadeco"), the leading provider of oilfield solids
control equipment in Canada, for total consideration of $21.6 million.
Consideration consisted of the assumption of $5.2 million in debt and cash of
$16.4 million for the stock of the privately-held company.  On a pro forma
consolidated basis for the year ended April 30, 1996, Wadeco posted $2.2 million
in income and $6.0 million in earnings before depreciation, interest, taxes, and
amortization, excluding certain non-recurring items, on revenues of $13.0
million pro forma book capitalization for the Company is approximately $16.8
million.

"The acquisition of Wadeco puts Tuboscope Vetco International into the only
major oilfield solids control market where we did not have a presence," said
John F. Lauletta, President and Chief Executive Officer of Tuboscope.  "By
acquiring the market leader, we enter the Canadian market with a large ongoing
operation, and further enhance Tuboscope's position as the world's leading
provider of oilfield solids control equipment."  The transaction marks
Tuboscope's first acquisition since the Company merged with Drexel Oilfield
Services in April, and exemplifies its strategy of growth through acquisitions
in its major product lines.  Solids control equipment and technology are used to
separate cuttings from the drilling fluids used in oil and gas drilling
operations.  Both Tuboscope, through its Brandt/EPI divisions, and Wadeco have
benefitted in 

                                       63

recent years from a trend to use higher technology equipment to improve drilling
efficiency and minimize the environmental impact of drilling operations. Wadeco
owns and operates a fleet of 137 centrifuges and various other pieces of solids
control equipment, which it rents to oil and gas operators and drilling
contractors across western Canada, Newfoundland, Nova Scotia, and in North
Dakota. Wadeco is based in Leduc, Alberta, with offices in Calgary, Grand
Prairie, and Estevan, Saskatchewan.

Tuboscope Veto International is the world's leading supplier of oilfield tubular
coating and inspection services, oilfield solids control equipment and services,
and coiled tubing equipment to the petroleum industry; and additionally, it
supplies in-service inspection for oil and gas pipelines; sells and leases
advanced in-line inspection equipment to the makers of oil country tubular
goods; and provides quality assurance and inspection services to a diverse range
of worldwide industries.  Tuboscope is headquartered in Houston, Texas and
services markets in more than 54 countries.  1995 pro forma revenues, including
the full-year effect of its Drexel acquisition, together with acquisitions made
by Drexel in 1995, was $315 million.
