     to any liens or other encumbrances. TVI agrees to hold harmless, defend,
     and indemnify KARLSSON and TVIES from and against any and all liens or
     encumbrances associated with the EQUIPMENT.

                                   ARTICLE 2

                              LICENSE OF PATENTS
                              ------------------

2.1  Subject to the terms and conditions of this Agreement, TVI grants to
     KARLSSON and TVIES, and KARLSSON and TVIES accept from TVI an exclusive
     (except for TVI'S retained rights), non-transferable license to make, have
     made, use, and sell apparatus under the following patents:

            (i)    U.S. Patent No. 5,290,456

            (ii)   U.S. Patent No. 5,368,411

            (iii)  U.S. Patent No. 5,302,287

            (iv)   U.S. Patent No. 5,265,978
 
            (v)    U.S. Patent No. 5,288,330

(hereinafter collectively the "PATENTS")(the term "PATENTS" shall expressly
include any attendant know-how associated with them) in the conduct of TVIES's
business; and under any re-issues or extensions of any of said PATENTS; and
under any foreign patent applications or patents. Provided however, TVI
expressly reserves unto itself, including its parent, affiliates and
subsidiaries, all rights in and to the PATENTS, the right to use the PATENTS in
its businesses, and the right to make, have made and use the PATENTS provided
that TVI shall not use the PATENTS in direct competition with KARLSSON or TVIES
for a period of five (5) years from the Effective Date. However, in the event
KARLSSON and TVIES meet all obligations under this Agreement and purchase the
PATENTS pursuant to Section 2.5 and Article 4, then TVI will not engage in any
direct competition with KARLSSON and TVIES for the life of the PATENTS. For
purposes of this Section, direct competition is defined as any business of soil
washing using the technology embodied under the PATENTS. Provided further that
use of the PATENTS by TVI for its own account shall not be deemed as direct
competition for purposes of this restriction.

 
2.2  The rights granted herein to KARLSSON and TVIES may be extended and sub-
     licensed to wholly-owned subsidiaries of TVIES provided that each such
     subsidiary to which rights are extended shall agree in writing to abide by
     all of the terms and conditions of this Agreement before being given access
     to any of the PATENTS, and KARLSSON and/or TVIES shall provide TVI with a
     copy of each such agreement promptly after its execution. It is understood
     and agreed that KARLSSON and TVIES shall remain responsible for (i) the
     payment of all license fees associated with any use of the PATENTS by any
     of its subsidiaries or sub-licensees and (ii) any breach of any term of
     this Agreement by any of TVIES' subsidiaries or sub-licensees.

2.3  KARLSSON and TVIES agree that should KARLSSON or TVIES develop any
     improvements in the PATENTS, it will promptly furnish a generalized
     description of such improvements to TVI upon commercial reduction to
     practice and, upon TVI'S written request, furnish details of such
     improvements and grant to TVI non-exclusive rights and licenses to make,
     have made and use such improvements on the same terms granted to KARLSSON
     and TVIES under this Agreement, provided that TVI does not use such
     improvements in direct competition with KARLSSON or TVIES.

2.4  In the event that this Agreement is terminated, for any reason, prior to
     the five (5) year expiration, KARLSSON and TVIES agree that TVI shall have,
     and do hereby grant to TVI an irrevocable, royalty free, non-exclusive
     right and license to use any such improvements or enhancements made to the
     PATENTS whether or not those improvements or enhancements are patented.

2.5  At such time that KARLSSON and TVIES have met all obligations under this
     Agreement, including payment in full of all monies due under Article 4,
     KARLSSON and TVIES shall have the option to purchase all right (except for
     TVI's retained rights) and title to the PATENTS for the consideration of
     One Dollar and No Cents ($1.00). If KARLSSON and TVIES have made payment in
     full under this Section 2.5, then TVI shall retain an exclusive, royalty
     free, paid up license to make, have made, and use the PATENTS as set forth
     in Sections 2.1, 2.3 and 2.4.

2.6  TVI hereby represents and warrants to KARLSSON and TVIES that TVI has good
     and valid title to the PATENTS and that none of the PATENTS are subject to
     any liens or other encumbrances. TVI also represents and warrants that to
     the best of its knowledge, use of the PATENTS will not constitute an
     infringement of any patent or registered design. TVI agrees to defend, hold
     harmless, and indemnify KARLSSON AND TVIES from and against any and all
     claims, demands, or lawsuits alleging patent infringement on the PATENTS
     described under this Article.

 
                                   ARTICLE 3

                      USE OF TRADEMARKS AND SERVICE MARKS
                      -----------------------------------

3.1  KARLSSON and TVIES acknowledge that TVI either owns or has the right to use
     the following marks:

        (i)   "TUBOSCOPE"

        (ii)  "VETCO"

        (iii) "TUBOSCOPE VETCO INTERNATIONAL"

     or any colorable imitations or variations thereof (hereinafter collectively
     the "MARKS") as trademarks or service marks.

3.2  TVI hereby grants to KARLSSON and TVIES the right to use the MARKS as
     trademarks and service marks in connection with the sale or offering for
     sale or lease of any goods or the rendering of any services pursuant to the
     provisions of this Agreement.

3.3  Any use of the MARKS by KARLSSON or TVIES shall inure to the benefit of
     TVI. Neither KARLSSON nor TVIES shall assert any claim of right, title, or
     ownership therein or the goodwill represented thereby other than the rights
     granted by this Agreement.

3.4  Unless otherwise waived in writing by TVI, any use of the MARKS shall also
     contain a disclaimer as follows:

        "TVIES Inc. and/or Tuboscope Vetco International Environmental Services
        Inc. is an independent company and not affiliated with Tuboscope Vetco
        International Inc."

3.5  Notwithstanding the foregoing, all rights granted under this Article 3
     expressly expire six (6) months from the date hereof unless extended by
     written mutual agreement by the parties to this Agreement. It is expressly
     understood and agreed to by the Parties that the rights granted under this
     Article 3 are for transitional purposes only.

3.6  Upon the termination of the rights granted in this Article 3 for any
     reason, the provisions of Paragraph 3.1 of this License Agreement shall
     nevertheless continue in full force and effect and KARLSSON and TVIES shall
     thereafter refrain from any use of the MARKS, any confusingly similar mark
     or any mark which constitutes any variation thereof for so long as TVI, its
     licensees or assigns, shall continue to use the MARKS.

 
3.7  All use of the MARKS by KARLSSON or TVIES shall be subject to review and
     approval by TVI. KARLSSON and TVIES shall permit TVI, upon reasonable
     notice, to inspect any apparatus, parts or equipment made by KARLSSON or
     TVIES under the MARKS and to review all advertising material using the
     MARKS distributed by KARLSSON or TVIES.

3.8  It is expressly understood and agreed that KARLSSON or TVIES may do
     business as Tuboscope Vetco International Environmental Services Inc., but
     if KARLSSON or TVIES decide to do business under that name, they will file
     a "dba" statement in any state, county, or otherwise appropriate office in
     which they so engage in business. This right to do business under that name
     expressly expires six (6) months from the date hereof unless extended by
     written mutual agreement by the parties. It is expressly understood and
     agreed to by the Parties that the rights granted under this Article 3 are
     for transitional purposes only.

3.9  KARLSSON and TVIES hereby agree and acknowledge that the MARKS, while
     registered in many parts of the world, including the United States, are
     "Worldwide Marks" and KARLSSON and TVIES agree that any rights granted
     under this Article 3 expressly expire six (6) months from the Effective
     Date including any use of the MARKS worldwide.

                                   ARTICLE 4

             LICENSE FEES, LEASE PAYMENTS AND OTHER CONSIDERATION
             ----------------------------------------------------

4.1  KARLSSON and/or TVIES shall pay TVI, as consideration for all covenants,
     licenses, rights to use, and leases under this Agreement, the sum of One
     Million Eighty Thousand Dollars and No Cents ($1,080,000.00). Such sum
     shall be paid as follows:

        (a) Quarterly payments equal to seven percent (7%) of the Gross Revenue
            for each quarter of TVIES and its subsidiaries throughout the term
            of this Agreement up to a maximum aggregate Of $l,080,000.00. The
            quarterly payments shall be made for revenues actually received by
            KARLSSON and/or TVIES or by its successors, assigns or the like.

        (b) At such time as the full amount ($l,080,000.00) has been paid to
            TVI, KARLSSON and/or TVIES shall then immediately have the option to
            acquire all rights and title to the EQUIPMENT as set forth in
            Article 1 of this Agreement. KARLSSON and/or TVIES shall at such
            time also have the option to acquire all rights (except for TVI's
            reserved rights) and title to the PATENTS as set forth in Article 2
            of this Agreement.

 
        (c) If at the end of the five (5) year period the total amount
            ($1,080,000.00) has not been paid, KARLSSON and/or TVIES may make a
            final lumpsum payment equal to the remaining unpaid balance. If such
            a payment is not made at the expiration of this Agreement, all
            EQUIPMENT, as described in Appendix A, shall be immediately
            returned, and all rights to the PATENTS granted to KARLSSON and/or
            TVIES under this Agreement shall automatically terminate and revert
            to TVI. TVI shall be free of any restrictions with respect to the
            PATENTS and MARKS.

4.2  The above referenced quarterly payments shall be due and payable within
     fifteen (15) days after the end of each calendar quarter commencing with
     the quarter during which the Effective Date first takes place.

                                   AGREEMENT

This Agreement is made and entered into on the 1st day of August, 1995
("Effective Date"), by and among Tuboscope Vetco International Inc., a Texas
corporation ("TVI"), TVIES, Inc. (f/k/a Tuboscope Vetco International
Environmental Services, Inc.) ("TVIES") and Haraldur Karlsson ("HK"). TVI and
TVIES are hereinafter sometimes collectively referred to as "Tuboscope".
Tuboscope and HK are hereinafter sometimes referred to as "Parties".

WHEREAS, HK entered into an employment agreement with TVI on or about March 4,
1993 as amended on April 27, 1993 (the "Employment Agreement"); and

WHEREAS, the Parties wish to terminate the Employment Agreement and enter into
this new Agreement to provide for the future relationship of TVI and HK; and

WHEREAS, the Parties understand and acknowledge that this document constitutes
an offer to HK by TVI and that by signature and acceptance hereof HK
acknowledges that he has read and understood the terms of this Agreement in full
and that his signature on this Agreement was done so knowingly and voluntarily.
HK acknowledges that TVI has recommended that he consult with an attorney about
this Agreement and his rights prior to signing it. HK and TVI understand and
acknowledge that he will not waive or give up any rights or claims he may have
against TVI that may arise from acts occurring after the date that he signs this
Agreement.

TVI's offer, as described in this document, will be open and effective until
August 29, 1995. HK may elect to accept or reject this offer within that time
period. If no signed Agreement is returned to TVI by August 29, 1995, the offer
will be considered withdrawn by TVI.

If HK signs this Agreement and waives certain rights against TVI, HK shall have
seven (7) days following the return of the signed Agreement to TVI in order to
change his mind and revoke the Agreement. In other words, the Agreement shall
not become effective until seven (7) days have passed following the tender of
the signed Agreement by HK. Upon the expiration of the seven (7) day period, the
Agreement shall be retroactive to the Effective Date; and

WHEREAS, pursuant to the Employment Agreement, HK is entitled to certain
benefits which include four (4) weeks vacation pay, separation pay, benefit
continuation, and the right to convert, at the end of that period at HK's
expense, his hospitalization, major medical and dental insurance, which
conversion is provided for under federal law known as COBRA. (Nothing contained
herein is intended or shall effect these COBRA rights); and

WHEREAS, the benefits Listed above belong to HK even if he does not decide to
sign this Agreement. However, signature of this Agreement by HK, which signature
is not revoked under the provisions contained herein thereby waiving his rights
as further described in this document, will entitle HK to the additional
consideration over and above the amounts and benefits he would normally be
entitled; and

 
WHEREAS, TVI as the sole shareholder of TVIES wishes to sell all its rights,
title, and interest to the shares of common stock of TVIES and HK wishes to
acquire all rights, title, and interest in and to all of the shares common stock
of TVIES

NOW THEREFORE, in consideration of the premises, mutual covenants and promises
made herein and other good and valuable consideration, as more specifically set
forth herein, the adequacy and sufficiency of which is hereby specifically
acknowledged and agreed, the Parties agree as follows:

1. As of August 1, 1995, HK shall have ceased performing in his capacity as
   "President-Tuboscope Vetco International Environmental Services Inc.".

2. HK shall receive the equivalent of six (6) months pay in equal bi-monthly
   installments. In addition, HK shall receive four (4) weeks vacation pay. Any
   payments hereunder shall be considered income and subject to any withholding.
   From August 1, 1996 until February 1, 1996 HK shall receive a car allowance
   of Eight Hundred Dollars and No Cents ($800.00) per month.

3. In exchange for the consideration recited herein and for the further
   consideration of Ten Dollars and No Cents ($10.00) TVI shall sell, and
   otherwise for all purposes transfer to HK all outstanding shares of common
   stock of TVIES consisting of one thousand (1,000) shares of common stock with
   a par value of $0.01/share. TVI hereby represents and warrants to HK that TVI
   has good and valid title to the outstanding shares of common stock of TVIES
   and that none of the shares are subject to any liens or encumbrances. Such
   transfer shall be accomplished by transferring TVI's Certificate No. 1 of
   1,000 shares of Tuboscope Vetco International Environmental Services Inc.
   common stock to HK. Notwithstanding anything to the contrary, said share
   transfer shall be effective August 17, 1995. Immediately upon such transfer,
   HK as the sole shareholder, shall appoint a new Board of Directors, cancel
   share Certificate No. 1, and issue such certificates in the name of TVIES,
   Inc. to such shareholders as HK deems appropriate.

4. It is understood, agreed and acknowledged by the Parties that except for the
   assets listed on the attached Appendix "A", TVIES has no other asset, either
   tangible or intangible.

5. HK shall be provided medical benefits and certain life insurance benefits as
   if he were a fully active employee pursuant to TVI's Medical Benefits Plan
   and Life Insurance Plans, or any successor plans until February 1, 1996, and
   HK shall continue to make the required contributions therefor.

6. It is agreed that the medical coverages provided in paragraph 5 above shall
   continue as therein set forth unless and until HK shall become eligible for
   group medical insurance pursuant to his employment with another employer
   which provides equivalent or superior medicaI benefits and coverage. At such
   time, HK will so notify TVI and TVI's obligation to provide the coverage set
   forth in paragraph 5 above shall cease.

                                       2

 
7.  HK agrees to knowingly and voluntarily, waive, settle, release and discharge
    TVI of any and all claims, demands, damages, actions or causes of action,
    including any claim for attorney's fees, which HK may have against TVI, its
    subsidiaries and affiliates and the officers, directors, employees, and
    agents of each of them arising out of or relating to his employment or
    arising out of his separation of employment with TVI. HK understands and
    acknowledges that this waiver of rights includes any claims of HK arising
    under any federal, state or local laws or regulations pertaining to
    discrimination on the basis of sex, race, color, religion, creed, national
    origin, age or handicap status or to retaliation on any grounds and
    particularly any rights of HK pursuant to the Age Discrimination in
    Employment Act, The Texas Human Rights Commission Act, The Older Workers
    Benefit Protection Act, or Title VII of the Civil Rights Act of 1964. HK
    acknowledges that he waives his right to file suit or file a charge under
    state law for any claim under the laws and statutes named in the paragraph
    above. HK further waives his right to claim or receive damages as a result
    of any charge of discrimination or lawsuit which may be filed by HK or
    anyone acting on HK's behalf.

8.  TVI agrees to hold harmless and indemnify HK and TVIES from any and all
    costs, claims, demands, or liabilities arising out of the failure to pay any
    vendor of TVIES for materials, supplies or services provided by the vendor
    prior to August 1, l995.

    In addition to the indemnification above, TVI agrees to hold harmless and
    indemnify HK and TVIES from any and all costs, claims, demands, or
    liabilities arising out of the operations of TVI or any of its subsidiaries
    other than TVIES

9.  This Agreement and all rights under this Agreement shall be binding upon and
    inure to the benefit of and be enforceable by the parties hereto and their
    respective personal or legal representatives, executors, administrators,
    heirs, distributees, devisees, legatees, successors, and assigns. This
    Agreement is personal in nature, and none of the parties to this Agreement
    shall, without the written Agreement of the other party assign any right or
    obligation to this Agreement to any other person or entity. Anything to the
    contrary in the foregoing notwithstanding, the covenants contained in this
    Agreement shall continue to be applicable whether TVI's business is
    conducted by it, by any subsidiary of TVI; or by any other successor to the
    business of TVI.

Board of Directors
DK Industries, Inc.
1580 Lincoln St., Suite 1125

Gentlemen:

     1. CONSIDERATION FOR PURCHASE. The undersigned (the "Purchaser") has
        --------------------------                                       
entered into a Reorganization Plan dated September 30, 1996, under the terms of
which the undersigned has agreed to exchange one thousand (1,000) shares of
TVIES, Inc. common stock, being all of the issued and outstanding stock of that
corporation for thirty-three thousand three hundred thirty-three (33,333) shares
of common stock of DK Industries, Inc.

     2.  UNDERSTANDINGS OF THE PURCHASER. The Purchaser acknowledges understands
         -------------------------------                                      
and agrees that:

          (a) The certificates representing the Shares will bear a legend
restricting its transfer for a period of time as provided under Regulation S
promulgated under the Securities Act of 1933, as amended (the "Act"); further,
the Shares are subject to the restrictions on transfer pursuant to the
aforementioned legend and as provided in Regulation S; and further, the Shares
or a portion thereof, if this subscription is accepted in whole or in part, will
be issued in the name set forth under the signature line below.

          (b) The Shares have not been registered under the Act or any
applicable state law (collectively, the "Securities Acts"). The Shares may not
be sold, offered for sale, transferred, pledged, hypothecated or otherwise
disposed of except in compliance with the Securities Acts. The

 
Company has no obligation, and does not intend, to cause any of the Shares to be
registered under the Securities Acts or to comply with any exemption under the
Securities Acts which would permit a sale or sales of the Share. The legal
consequences of the foregoing are that the Purchaser will be required to bear
the economic risk of his investment in the Shares for the aforesaid period of
time. If the Purchaser desires to sell or transfer all or any part of the
Shares, the Company may require the Purchaser's counsel to provide a legal
opinion that the transfer may be made without registration under the Securities
Acts. Other restrictions discussed elsewhere herein may be applicable. The
Purchaser is subject to the restrictions on transfer described herein and the
Company will issue stop transfer orders to its transfer agent in order to
enforce such restrictions.

     (c) No federal or state (U.S.A.) agency has made any findings or
determination as to the fairness of an investment in the Company, or any
recommendation or endorsement of this investment.

     (d) Only a limited market exists for the resale of the Shares and no market
may exist in the future for any sale or sales.

  3. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER. The Purchaser hereby
     -----------------------------------------------                      
represents and warrants to the Company as follows:

     (a) My commitment to investments that are not readily marketable is not
disproportionate to my net worth and my investment in the Shares will not cause
such overall commitment to become excessive.

     (b) I have the financial ability to bear the economic risk of an investment
in the Shares, adequate means for providing for my current needs and personal
contingencies and no need for liquidity with respect to this investment.

     (c) I have evaluated the high risk of investing in the Shares and I have
such knowledge and experience in financial and business matters in general and
in particular with respect to this type of investment that I am capable of
evaluating the merits and risks of an investment in the Shares.

     (d) I have been given the opportunity to ask questions of and receive
answers from the Company concerning the terms and conditions of this investment
and to obtain additional information necessary to verify the accuracy of the
information I desired in order to evaluate this investment. In evaluating the
suitability of an investment in the Shares, I have not relied upon any
representations or other information (whether verbal or written) other than that
furnished by the Company or its representatives.

     (e) I have had the opportunity to discuss with my professional legal, tax
and financial advisers the suitability of an investment in the Shares for my
particular tax and financial situation and all information that I have provided
to the Company concerning me and my financial position is correct and complete
as of the date set forth below. If there should be any material change

                                       2

 
in such information prior to my admission as a shareholder of the Company, I
will immediately provide such information to the Company.

     (f) I am acquiring the Shares solely for my own personal account for
investment purposes only, and I am not purchasing the Shares with a view to the
resale, distribution, subdivision or fractionalization thereof.

     (g) I am neither a member of, nor am I affiliated with or employed by, a
member of the National Association of Securities Dealers, Inc., a broker-dealer
registered with the Commission or any similar agency of any state.

     (h) I am not acting alone or in concert with others in a transaction or
series of transactions intended to circumvent the registration requirements of
the Securities Acts.

     (i) The Purchaser understands that the Company is the issuer of the
securities which are the subject of this agreement, and that, for purposes of
Regulation S, a "distributor" is any underwriter, dealer or other person who
participates, pursuant to a contractual arrangement, in the distribution of
securities offered or sold in reliance on Regulation S and that an "affiliate"
is any partner, officer, director or any person directly or indirectly
controlling, controlled by or under common control with the person in question.
In this regard, the Purchaser shall not, during the applicable period of time as
provided under Regulation S act as a distributor of the Shares, either directly
or through an affiliate, nor shall the Purchaser sell, transfer, hypothecate to
otherwise convey the Shares or any interest therein, other than to a non-U.S.
person.

     (j) Neither the Purchaser nor any affiliate of the Purchase, will receive
