                    INFORMATION TO BE INCLUDED IN THE REPORT

ITEM 5.   OTHER EVENTS.

MERGER AGREEMENT
- ----------------

       On January 3, 1996, Tuboscope Vetco International Corporation, a Delaware
corporation ("Tuboscope"), Grow Acquisition Limited, a Bermuda corporation and
wholly owned subsidiary of Tuboscope ("Grow"), and D.O.S. Ltd., a Bermuda
corporation ("DOS"), entered into an Agreement and Plan of Merger (the "Merger
Agreement"), providing for the merger (the "Merger") of Grow with and into DOS,
with DOS continuing as the surviving corporation and wholly owned subsidiary of
Tuboscope.

       Conditions to the Merger; Effective Time.  The obligations of Tuboscope
and DOS to consummate the Merger are subject to the satisfaction of certain
conditions set forth in the Merger Agreement, including, among others, (i)
obtaining requisite Tuboscope and DOS stockholder approvals and requisite
regulatory approvals (including the expiration or termination of the waiting
period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended) and (ii) the compliance by SCF-III, L.P. ("SCF") with its obligations
under the Subscription Agreement (as defined below).  Upon the satisfaction or
waiver of all conditions to the Merger, the Merger will be effected upon the
filing of a certificate of amalgamation, prepared and executed in accordance
with the Companies Act 1981 of Bermuda, as amended, with the Bermuda Registrar
of Companies.  The date and time of such filing is referred to herein as the
"Effective Time."

       Conversion of Securities.  Pursuant to the Merger Agreement, at the
Effective Time the shares of DOS Common Stock outstanding immediately prior to
the Effective Time will be converted into an aggregate of up to approximately
16,700,000 shares of Tuboscope Common Stock.

       Treatment of Stock Options.  At the Effective Time, all options to
purchase shares of DOS Common Stock (individually, a "DOS Option") outstanding
under the DOS 1993 Stock Option Plan and stock option agreements of certain
former stockholders of subsidiaries of DOS (the "DOS Stock Option Plans")
granted on or prior to the Effective Time, whether or not currently exercisable,
will remain outstanding and will be assumed by Tuboscope. Thereafter, such
options will be exercisable upon the same terms and conditions as under the
applicable DOS Stock Option Plan and the applicable option agreement issued
thereunder, except that the number of shares of Tuboscope Common Stock subject
to, and the per share exercise price of, each DOS Option will be adjusted to
give effect to the Merger.

       Management After the Merger.  Following the consummation of the Merger,
Tuboscope's Board of Directors will be comprised of Jerome R. Baier, John
Lauletta, J.S. Dickson Leach, Eric L. Mattson, Martin R. Reid, L.E. Simmons, and
an individual to be mutually agreed upon by Tuboscope and DOS.

       Following the consummation of the Merger, L.E. Simmons, currently the
Chairman of the Board of DOS, will be the Chairman of the Board of Tuboscope,
John Lauletta, currently the Chief Executive Officer of DOS, will be the
President and Chief Executive Officer of Tuboscope, Joseph Winkler, currently
the Chief Financial Officer of DOS, will be the Chief Financial Officer of
Tuboscope, Gerhard H. Hage will continue to be the Senior Vice President-
International Operations, Martin I. Greenberg will continue to be the Vice
President, Controller, Assistant Treasurer and Assistant Secretary, Kenneth L.
Nibling will continue to be the Vice President-Human Resources and
Administration and James F. Maroney will continue to be the Vice President,
Secretary and General Counsel.

THE SUBSCRIPTION AGREEMENT
- --------------------------

       In connection with the Merger, Tuboscope will sell (the "SCF Sale") to
SCF 4,200,000 shares Tuboscope Common Stock and warrants to purchase, subject to
adjustment under certain circumstances, an aggregate of 2,533,000 shares of
Tuboscope Common Stock at an exercise price of $10 per share, for an aggregate
purchase price of $31,000,000, pursuant to a Subscription Agreement dated as of
January 3, 1996 between Tuboscope and SCF.

       The obligations of Tuboscope and SCF to effect the SCF Sale are subject
to the satisfaction of certain conditions, including, among others, (i) the
satisfaction by Tuboscope and DOS of the condition precedents to the Merger and
(ii) the making of all filings with, and the receipt of all consents, approvals,
permits and authorizations from, any government entity except where the failure
to obtain such consents, approvals, permits and authorizations would not be
likely to have a material adverse effect.

       The Subscription Agreement is subject to termination by either SCF or
Tuboscope if (i) the SCF Sale does not occur by June 30, 1996 or (ii) the Merger
Agreement is terminated.  If the Merger Agreement is terminated, SCF may be
entitled to receive a termination fee from DOS under certain circumstances.  In
addition, the Subscription Agreement may be terminated by the mutual agreement
of Tuboscope and SCF.

EXCHANGE OF SERIES A CONVERTIBLE PREFERRED STOCK
- ------------------------------------------------

       In connection with the Merger and SCF Sale, Baker Hughes Incorporated
("Baker Hughes") has agreed, subject to final documentation, to exchange all of
its 100,000 shares of Series A Convertible Preferred Stock, par value $.01 per
share, of Tuboscope for 1,500,000 shares of Tuboscope Common Stock and warrants
to purchase up to an additional 1,250,000 shares of Tuboscope Common Stock at an
exercise price of $10 per share.  A condition to the closing of this transaction
will be the consummation of the Merger.

                         AGREEMENT AND PLAN OF MERGER
                                        
     AGREEMENT AND PLAN OF MERGER, dated as of January 3, 1996 (this
"Agreement"), among Tuboscope Vetco International Corporation, a Delaware
corporation ("Parent"), and Grow Acquisition Limited, a Bermuda corporation to
be formed by Parent as a direct wholly owned subsidiary of Parent ("Sub"), and
D.O.S. Ltd., a Bermuda corporation (the "Company").

     WHEREAS, the Boards of Directors of Parent and the Company each have
determined that it is in furtherance of and consistent with their respective
long-term business strategies and is fair to and in the best interests of their
respective stockholders for Sub to merge with and into the Company (the
"Merger") upon the terms and subject to the conditions of this Agreement;

     WHEREAS, in accordance with the understanding of Parent and the Company,
concurrently herewith:  (i) the Company is entering into a Voting Agreement with
each of Baker Hughes Incorporated and Brentwood Associates IV, LP and (ii)
Parent is entering into a Voting Agreement with each of DOS Partners L.P.,
Panmell (Holdings), Ltd. and Zink Industries Limited;

     WHEREAS, in accordance with the understanding of Parent and the Company,
concurrently herewith SCF-III, L.P., an affiliate of a stockholder of the
Company, is entering into a Subscription Agreement with Parent (the
"Subscription Agreement") whereby SCF-III, L.P. is agreeing to purchase for an
aggregate purchase price of $31,000,000 in connection with the Closing (as
defined herein) 4,200,000 shares of Parent Common Stock (as defined herein) and
warrants (the "Warrants") to purchase, subject to adjustment under certain
circumstances, an aggregate of 2,533,000 shares of Parent Common Stock at an
exercise price of $10 per share;

     WHEREAS, for federal income tax purposes, it is intended that the Merger
and the Liquidation (as defined herein) shall collectively qualify as a
reorganization within the meaning of Section 368(a) of the United States
Internal Revenue Code of 1986, as amended (the "Code");

     WHEREAS, Parent, Sub and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and also to prescribe various conditions to the Merger;

     NOW, THEREFORE, in consideration of the foregoing and the representations,
warranties, covenants and agreements herein contained, the parties agree as
follows:

                                   ARTICLE I
                                        
                                   THE MERGER
                                        
     1.1  The Merger; Effective Time of the Merger.  Upon the terms and
conditions of this Agreement and in accordance with the Companies Act 1981 of
Bermuda, as amended 

                                     -20-
<PAGE>
 
(the "Bermuda Act"), Sub shall be merged with and into the Company at the
Effective Time (as hereinafter defined). The Merger shall become effective as of
the date indicated in a certificate of amalgamation (the "Certificate of
Merger"), prepared and executed in accordance with the relevant provisions of
the Bermuda Act, that is filed with the Registrar of Companies pursuant to the
Bermuda Act (the "Effective Time"). The filing of the Certificate of Merger
shall be made upon, or as soon as practicable after, the closing of the Merger
(the "Closing").

     1.2  Closing.  The Closing shall take place at 10:00 a.m. on the first
business day after satisfaction (or waiver in accordance with this Agreement) of
the latest to occur of the conditions (other than deliveries of instruments to
be made at Closing) set forth in Article VI (the "Closing Date"), at the offices
of Baker & Botts, L.L.P., 910 Louisiana, Houston, Texas 77002 unless another
date or place is agreed to in writing by the parties.

     1.3  Effects of the Merger.  (a)  At the Effective Time: (i) Sub shall be
merged with and into the Company, the separate existence of Sub shall cease and
the Company shall continue as the surviving corporation (Sub and the Company are
sometimes referred to herein as the "Constituent Corporations" and the Company
is sometimes referred to herein as the "Surviving Corporation"); (ii) the
Memorandum of Association of the Company as in effect immediately prior to the
Effective Time shall be the Memorandum of Association of the Surviving
Corporation; and (iii) the Bye-laws of the Company as in effect immediately
prior to the Effective Time shall be the Bye-laws of the Surviving Corporation.

     (b) The individuals listed on Exhibit A hereto (which Exhibit indicates the
address of each such individual) shall, from and after the Effective Time, be
the initial directors and officers of the Surviving Corporation and shall serve
until their successors have been duly elected or appointed and qualified or
until the Liquidation or their earlier death, resignation or removal in
accordance with the Surviving Corporation's Memorandum of Association and Bye-
laws.

     (c) The Merger shall have such other effects as specified in the Bermuda
Act.

     1.4  Liquidation of Surviving Corporation.  As soon as practicable after
the Effective Time, Parent shall cause the Surviving Corporation to be
liquidated into Parent (the "Liquidation") so that the Merger and the
Liquidation will be collectively treated for federal income tax purposes as a
reorganization within the meaning of Section 368(a) of the Code.

                                   ARTICLE II
                                        
                EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES
                                        
     2.1  Effect on Capital Stock .  At the Effective Time, by virtue of the
Merger and without any action on the part of Parent, the Constituent
Corporations or their respective stockholders:

                                     -21-
<PAGE>
 
     (a) Capital Stock of Sub.  Each issued and outstanding share of the
capital stock of Sub shall be converted into and become one fully paid and
nonassessable ordinary share, par value $0.10 per share, of the Surviving
Corporation.

     (b) Cancellation of Parent-Owned Stock.  Each ordinary share, par value
$0.10 per share, of the Company ("Company Common Stock") owned by Parent, Sub or
any other wholly owned Subsidiary (as hereinafter defined) of Parent or the
Company shall be canceled and retired and shall cease to exist and no stock of
Parent or other consideration shall be delivered or deliverable in exchange
therefor.  As used in this Agreement, "Subsidiary" means, with respect to any
party, any corporation or other organization, whether incorporated or
unincorporated, of which: (i) such party or any other Subsidiary of such party
is a general partner (excluding partnerships, the general partnership interests
of which are held by such party or any Subsidiary of such party that do not have
a majority of the voting interest in such partnership); or (ii) at least a
majority of the securities or other interests having by their terms ordinary
voting power to elect a majority of the Board of Directors or others performing
similar functions with respect to such corporation or other organization is,
directly or indirectly, owned or controlled by such party or by any one or more
of its Subsidiaries, or by such party and any one or more of its Subsidiaries.

     (c) Exchange Ratio for Company Common Stock.  Subject to the provisions of
Section 2.2(e) hereof, each share of Company Common Stock issued and outstanding
immediately prior to the Effective Time (other than shares to be canceled in
accordance with Section 2.1(b) and Dissenting Shares (as hereinafter defined))
shall be converted into (i) .4372 shares of common stock, par value $0.01 per
share, of Parent ("Parent Common Stock") (such shares issuable upon such
conversion are referred to herein as the "Non-Escrowed Shares") and (ii) .0273
shares of Parent Common Stock which shall be subject to the provisions of
Section 2.4 and the Escrow Agreement (as hereinafter defined) (such shares
issuable upon such conversion are referred to herein as the "Escrowed Shares"
and together with the Non-Escrowed Shares, the "Shares").  All such shares of
Company Common Stock, when so converted, shall no longer be outstanding and
shall automatically be canceled and retired and shall cease to exist, and each
holder of a certificate representing any such shares shall cease to have any
rights with respect thereto, except the right to receive the shares of Parent
Common Stock and cash in lieu of fractional shares of Parent Common Stock as
contemplated by Section 2.2(e), to be issued or paid in consideration therefor
upon the surrender of such certificate in accordance with Section 2.2, without
interest.

     (d) Assumption of Stock Options.  Each outstanding Company Stock Option
(as defined in Section 5.10) shall be assumed by Parent as provided in Section
5.10.

     2.2  Exchange of Certificates

     (a) Exchange Agent.  As of the Effective Time, Parent shall deposit with
Chemical Shareholder Services Group, Inc. or such other bank or trust company
designated by Parent and reasonably acceptable to the Company (the "Exchange
Agent"), for the benefit of the holders of shares of Company Common Stock, for
exchange in accordance with this Article II, through the Exchange Agent,
certificates representing the Non-Escrowed Shares (such shares of Parent Common
Stock, together with any dividends or distributions with respect

                                     -22-
<PAGE>
 
thereto, being hereinafter referred to as the "Exchange Fund"). The Exchange
Agent shall, pursuant to irrevocable instructions, deliver the Non-Escrowed
Shares contemplated to be issued pursuant to Section 2.1 out of the Exchange
Fund. The Exchange Fund shall not be used for any other purpose.

     (b) Exchange Procedures.  As soon as reasonably practicable after the
Effective Time, the Exchange Agent shall mail to each holder of record of a
certificate or certificates which, immediately prior to the Effective Time,
represented outstanding shares of Company Common Stock (the "Certificates"),
which holder's shares of Company Common Stock were converted into the right to
receive shares of Parent Common Stock pursuant to Section 2.1: (i) a letter of
transmittal (which shall specify that delivery shall be effected and risk of
loss and title to the Certificates shall pass only upon delivery of the
Certificates to the Exchange Agent, and shall be in such form and have such
other provisions as Parent may reasonably specify); and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for certificates
representing shares of Parent Common Stock.  Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by Parent, together with such letter of transmittal, duly executed,
and any other required documents, the holder of such Certificate shall be
entitled to receive in exchange therefor certificates representing that number
of whole shares of Non-Escrowed Shares which such holder has the right to
receive pursuant to the provisions of this Article II, certificates representing
that number of whole shares of Escrowed Shares which such holder has the right
to receive pursuant to the provisions of this Article II to the extent and as of
such time as provided in the Escrow Agreement and cash in lieu of fractional
Shares as contemplated by Section 2.2(e) and the Escrow Agreement, and the
Certificates so surrendered shall forthwith be canceled.  In the event of a
transfer of ownership of Company Common Stock which is not registered in the
share transfer records of Company, certificates representing the appropriate
number of shares of Parent Common Stock may be issued to a transferee if the
Certificates representing such Company Common Stock are presented to the
Exchange Agent accompanied by all documents required to evidence and effect such
transfer and by evidence that any applicable stock transfer taxes have been
paid.  Until surrendered as contemplated by this Section 2.2, each Certificate
(other than Certificates representing shares to be canceled in accordance with
Section 2.1(b) or Dissenting Shares) shall be deemed at any time after the
Effective Time to represent only the right to receive upon such surrender the
certificates representing shares of Parent Common Stock and cash in lieu of any
fractional shares of Parent Common Stock as contemplated by this Section 2.2.
The Exchange Agent shall not be entitled to vote or exercise any rights of
ownership with respect to the Parent Common Stock held by it from time to time
hereunder, except that it shall receive and hold all dividends or other
distributions paid or distributed with respect thereto for the account of
persons entitled thereto.

     (c) Distributions with Respect to Unexchanged Shares.  No dividends or
other distributions with respect to Parent Common Stock declared or made before
or after the Effective Time with a record date after the Effective Time shall be
paid to the holder of any unsurrendered Certificate with respect to the right to
receive shares of Parent Common Stock represented thereby and no cash payment in
lieu of fractional shares shall be paid to any such holder pursuant to Section
2.2(e) until the holder of such Certificate shall surrender such Certificate
and, with respect to Escrowed Shares, until such other time as provided in the

                                     -23-
<PAGE>
 
Escrow Agreement.  Subject to the effect of applicable laws and the provisions
of the Escrow Agreement with respect to Escrowed Shares, following surrender of
any such Certificate (other than Certificates representing shares to be canceled
in accordance with Section 2.1(b) or Dissenting Shares), there shall be paid to
the holder thereof, without interest: (i) at the time of such surrender, the
amount of any cash payable in lieu of any fractional share of Parent Common
Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount
of dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of Parent Common Stock; and
(ii) at the appropriate payment date, the amount of dividends or other
distributions with a record date after the Effective Time but prior to surrender
and a payment date subsequent to surrender payable with respect to such whole
shares of Parent Common Stock.

     (d) No Further Ownership Rights in Company Common Stock.  All shares of
Parent Common Stock issued upon the surrender for exchange of shares of Company
Common Stock in accordance with the terms hereof (including any cash paid
pursuant to Section 2.2(c) or 2.2(e)) shall be deemed to have been issued in
full satisfaction of all rights pertaining to such shares of Company Common
Stock, subject, however, to the Surviving Corporation's obligation to pay any
dividends or make any other distributions with a record date prior to the
Effective Time that may have been declared or made by the Company on such shares
of Company Common Stock in accordance with the terms of this Agreement or prior
to the date hereof and which remain unpaid at the Effective Time, and after the
Effective Time there shall be no further registration of transfers on the share
transfer books of the Surviving Corporation of the shares of Company Common
Stock that were outstanding immediately prior to the Effective Time.  If, after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Article II.

     (e) No Fractional Shares.  No certificates or scrip representing
fractional shares of Parent Common Stock shall be issued upon the surrender for
exchange of Certificates pursuant to this Article II, and, except as provided in
this Section 2.2(e), no dividend or other distribution, stock split or interest
shall relate to any such fractional security, and such fractional interests
shall not entitle the owner thereof to vote or to any rights of a security
holder of Parent.  In lieu of any fractional share of Parent Common Stock, each
holder of shares of Company Common Stock who would otherwise have been entitled
to a fraction of a share of Parent Common Stock upon surrender of Certificates
for exchange pursuant to this Article II will be paid an amount in cash (without
interest) equal to the value of such fraction of a share based upon the closing
price of Parent Common Stock on the Nasdaq Stock Market on the date on which the
Effective Time shall occur (or if the Parent Common Stock shall not trade on the
Nasdaq Stock Market on such date, the first day of that Parent Common Stock
shall trade on the Nasdaq Stock Market thereafter).  All shares of Company
Common Stock held by a record holder shall be aggregated for purposes of
computing the number of shares of Parent Common Stock to be issued pursuant to
this Section 2.2(e).

     (f) Termination of Exchange Fund.  Any portion of the Exchange Fund and
any cash in lieu of fractional shares of Parent Common Stock made available to
the Exchange Agent that remain undistributed to the former stockholders of the
Company on or after the one-hundred eightieth day following the Effective Time
shall be delivered to Parent, upon

                                     -24-
<PAGE>
 
demand, and any stockholders of the Company who have not theretofore complied
with this Article II shall thereafter look only to Parent for payment of their
claim for Parent Common Stock, any cash in lieu of fractional shares of Parent
Common Stock and any dividends or distributions with respect to Parent Common
Stock.

     (g) No Liability.  Neither Parent nor the Company shall be liable to any
holder of shares of Company Common Stock or Parent Common Stock, as the case may
be, for such shares (or dividends or distributions with respect thereto) or cash
in lieu of fractional shares of Parent Common Stock delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.
Any amounts remaining unclaimed by holders of any such shares on the day
immediately preceding the day on which such amounts would otherwise escheat to
or become property of any governmental entity) shall, to the extent permitted by
applicable law, become the property of Parent free and clear of any claims or
interest of any such holders or their successors, assigns or personal
representatives previously entitled thereto.

     2.3  Dissenting Shares.   Notwithstanding anything in this Agreement to the
contrary, shares of Company Common Stock that are issued and outstanding
immediately prior to the Effective Time and which are held by stockholders who
have properly exercised appraisal rights with respect thereto under the Bermuda
Act (the "Dissenting Shares") shall not be converted into or represent the right
to receive shares of Parent Common Stock as provided in Section 2.1(c), but the
holders of Dissenting Shares shall be entitled to receive such payment of the
appraised value of such shares held by them from the Surviving Corporation as
shall be determined pursuant to the Bermuda Act; provided, however, that if any
such holder shall have failed to perfect or shall withdraw or lose the right to
appraisal and payment under the Bermuda Act, each such holder's shares shall
thereupon be deemed to have been converted as of the Effective Time into the
right to receive shares of Parent Common Stock, without any interest thereon, as
provided in Section 2.1(c), and upon surrender, in the manner provided in
Section 2.2 of the Certificate(s) representing such shares, such shares shall no
longer be Dissenting Shares.

     2.4  Escrowed Shares.   On the Closing Date, Parent, the Company, a wholly
owned Subsidiary of Parent designated by Parent or such other entity designated
by Parent and reasonably acceptable to the Company (the "Escrow Agent") and the
Stockholders Representative (as hereinafter defined) shall execute and deliver
an escrow agreement in the form attached as Exhibit B hereto (the "Escrow
Agreement").  The provisions of the Escrow Agreement are hereby incorporated by
reference into this Agreement.  Promptly after the Effective Time, Parent shall
deposit with the Escrow Agent the Escrowed Shares in accordance with this
Article II and the Escrow Agreement.  Prior to the Closing Date, holders of a
majority of the outstanding shares of Company Common Stock may, by written
notice to Parent, designate an individual or entity as the Stockholders
Representative for purposes of the Escrow Agreement (the "Stockholders
Representative"), which individual or entity need not be a holder of Company
Common Stock.  If no such Stockholders Representative is so designated prior to
the Closing, Parent shall designate an individual or entity to act in such
capacity.

                         REPRESENTATIONS AND WARRANTIES

     3.1  Representations and Warranties of the Company.  The Company
represents and warrants to Parent and Sub as follows:

     (a) Organization, Standing and Power.  Each of the Company and its
Subsidiaries is a corporation or partnership duly organized, validly existing
and in good standing under the laws of the jurisdiction of its incorporation or
organization, has all requisite power and authority to own, lease and operate
its properties and to carry on its business as now being conducted, and is duly
qualified and in good standing to do business in each jurisdiction in which the
business it is conducting, or the operation, ownership or leasing of its
properties, makes such qualification necessary, other than in such jurisdictions
where the failure so to qualify would not have a Company Material Adverse Effect
(as defined below).  The Company has heretofore delivered to Parent complete and
correct copies of its Memorandum of Association and Bye-laws and the
organizational documents of each of its Significant Subsidiaries.  All
Subsidiaries of the Company, the percentage of the Company's ownership of such
Subsidiaries, the identity and percentage ownership of all other persons with
equity interests in such Subsidiaries and their respective jurisdictions of
incorporation or organization are identified on Schedule 3.1(a) of the letter
dated and delivered to Parent on the date hereof (the "Company Letter"), which
relates to this Agreement and is designated therein as being the Company Letter.
As used in this Agreement: (i) a "Significant Subsidiary" means any Subsidiary
of the Company or Parent, as the case may be, that would constitute a
Significant Subsidiary of such party within the meaning of Rule 1-02 of
Regulation S-X of the Securities and Exchange Commission (the "SEC"); and (ii) a
"Company Material Adverse Effect" or "Company Material Adverse Change" shall
mean, any effect or change that is, individually or in the aggregate, materially
adverse to the business, operations, assets, condition (financial or otherwise)
or results of operation of the Company and its Subsidiaries taken as a whole
except for general economic changes and changes that may affect the industries
of the Company or any of its Subsidiaries generally.

     (b) Capital Structure.  As of the date hereof, the authorized capital
stock of the Company consists of 40,000,000 shares of Company Common Stock.  At
the close of business on December 1, 1995: 35,892,240 shares of Company Common
Stock were issued and outstanding and 1,659,466 shares of Company Common Stock
were reserved for issuance pursuant to the Company's 1993 Stock Option Plan and
certain stock option agreements (the "Sweco Options") entered into with certain
former stockholders of the Sweco Entities (as defined herein) identified on
Schedule 3.1(b) of the Company Letter (the Company's 1993 Stock Option Plan and
the Sweco Options are collectively referred to as the "Company Stock Option
Plans") with an aggregate exercise price of $2,658,591; and (ii) no bonds,
debentures, notes or other indebtedness having the right to vote (or convertible
into securities having the right to vote) on any matters on which the Company
stockholders may vote ("Company Voting Debt") were issued or outstanding.  All
outstanding shares of Company Common Stock have been duly authorized, validly
issued, fully paid and nonassessable and are not subject to preemptive rights.
Except as set forth on Schedule 3.1(b) of the Company Letter, all outstanding
shares of capital stock of the Subsidiaries of

                                     -26-
<PAGE>
 
the Company are owned by the Company, or a direct or indirect wholly owned
Subsidiary of the Company, free and clear of all liens, charges, encumbrances,
claims and options of any nature. Except as set forth in this Section 3.1(b) and
except for changes since December 1, 1995 resulting from the exercise of
employee stock options granted pursuant to, or from issuances or purchases
under, the Company Stock Option Plans, or as contemplated by this Agreement,
there are outstanding: (i) no shares of capital stock, Company Voting Debt or
other voting securities of the Company; (ii) no securities of the Company or any
Subsidiary of the Company convertible into or exchangeable for shares of capital
stock, Company Voting Debt or other voting securities of the Company or any
Subsidiary of the Company; and (iii) no options, warrants, calls, rights
(including preemptive rights), commitments or agreements to which the Company or
any Subsidiary of the Company is a party or by which it is bound in any case
obligating the Company or any Subsidiary of the Company to issue, deliver, sell,
purchase, redeem or acquire, or cause to be issued, delivered, sold, purchased,
redeemed or acquired, additional shares of capital stock or any Company Voting
Debt or other voting securities of the Company or of any Subsidiary of the
Company, or obligating the Company or any Subsidiary of the Company to grant,
extend or enter into any such option, warrant, call, right, commitment or
agreement. Except as set forth on Schedule 3.1(b) of the Company Letter, there
are no stockholder agreements, voting trusts or other similar agreements or
understandings to which the Company is a party or by which it is bound. Except
as set forth on Schedule 3.1(b) of the Company Letter, there are no restrictions
on the Company's ability to vote the stock held by the Company of any of its
Subsidiaries. Except as identified on Schedule 3.1(b) of the Company Letter,
neither the Company nor any of its Subsidiaries is a party to any agreement
granting registration rights to any holders of its securities. To the knowledge
of the Company, as of the date of this Agreement, no stockholder of the Company
or "group" within the meaning of Section 13(d)3 of the Securities Exchange Act
of 1934, as amended (the "Exchange Act") will be immediately after the Effective
Time the beneficial owner of more than 25% of the then outstanding Parent Common
Stock (excluding for such purpose any beneficial ownership attributable to the
Warrants).

     (c) Non-Subsidiaries Equity Investment.  Schedule 3.1(c) of the Company
Letter sets forth the book value of each investment by the Company or any of its
Subsidiaries in the voting securities, partnership interests or other equity
interests of any corporation, partnership or other entity (other than a
Subsidiary of the Company) and the nature and percentage of the Company's or its
Subsidiaries' ownership interests in such investment.  Except as set forth in
Schedule 3.1(c) of the Company Letter, the voting securities, partnership
interests or other equity interests of the Company or its Subsidiaries in such
investments are owned free and clear of all liens, charges and encumbrances.

     (d) Authority; No Violations; Consents and Approvals .

          (i) The Board of Directors of the Company has approved the Merger and
this Agreement, by unanimous vote of the directors, and declared the Merger and
this Agreement to be in the best interests of the stockholders of the Company.

of this Agreement and the Merger by the stockholders of the Company in
accordance with the Bermuda Act, to consummate the

                                     -26-

transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of the Company,
subject, with respect to consummation of the Merger, to approval of this
Agreement and the Merger by the stockholders of the Company in accordance with
the Bermuda Act. This Agreement has been duly executed and delivered by the
Company and, subject, with respect to consummation of the Merger, to approval of
this Agreement and the Merger by the stockholders of the Company in accordance
with the Bermuda Act, and assuming this Agreement constitutes the valid and
binding obligation of Parent and Sub, constitutes a valid and binding obligation
of the Company enforceable in accordance with its terms, subject, as to
enforceability, to bankruptcy, insolvency, reorganization and other laws of
general applicability relating to or affecting creditors' rights and to general
principles of equity.

          (ii) Except as set forth on Schedule 3.1(d) of the Company Letter, the
execution and delivery of this Agreement does not, and the consummation of the
transactions contemplated hereby and compliance with the provisions hereof will
not, conflict with, or result in any violation of, or default (with or without
notice or lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or to the loss of a material
benefit under, or result in the creation of any lien, security interest, charge
or encumbrance upon any of the properties or assets of the Company or any of its
Subsidiaries under, any provision of (i) the Memorandum of Association or Bye-
laws of the Company or any provision of the comparable charter or organizational
documents of any of its Subsidiaries, (ii) any loan or credit agreement, note,
bond, mortgage, or indenture applicable to the Company or any of its

made and the approval of the Merger and this Agreement by the stockholders of
the Company has been obtained, any judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to the Company or any of its
Subsidiaries or any of their respective properties or assets, other than, in the
case of clause (iii), any such conflicts, violations, defaults, rights, liens,
security interests, charges or encumbrances that, individually or in the
aggregate, would not have a Company Material Adverse Effect, materially impair
the ability of the Company to perform its obligations hereunder or prevent the
consummation of any of the transactions contemplated hereby.

          (iii) No consent, approval, order or authorization of, or
registration, declaration or filing with, or permit from any court,
administrative agency or commission or other governmental authority or
instrumentality, domestic or foreign (a "Governmental Entity"), is required by
or with respect to the Company or any of its Subsidiaries in connection with the
execution and delivery of this Agreement by the Company or the consummation by
the Company of the transactions contemplated hereby, as to which the failure to
obtain or make would have a Company Material Adverse Effect, except for: (A) the
filing of a premerger notification report by the Company under the Hart-Scott-
Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and the
expiration or termination of the applicable waiting period with respect thereto;
(B) the approval of the Minister of Finance of Bermuda and the filing of the
Certificate of Merger with the Registrar

     (e) Financial Statements.  The Company previously has delivered to Parent
a true and complete copy of:

          (i) the consolidated balance sheets of the Company and its
consolidated Subsidiaries as of March 31, 1994 and 1995, and the related
consolidated statements of operations, stockholders' equity and cash flows for
the fiscal years then ended on such dates, together with the notes thereto, in
each case audited by and accompanied by the report of KPMG Peat Marwick LLP,
independent accountants;

          (ii) the unaudited consolidated balance sheet of the Company and its
consolidated Subsidiaries as of October 31, 1995, and the related consolidated
statements of operations and cash flows for the seven months then ended;

          (iii) the combined balance sheet of Environmental Procedures, Inc.,
Venezuela Well Analysis, Venwell International, and Onea Corporation
(collectively, the "Sweco Entities") as of May 31, 1995, and the related
combined statements of operations, changes in stockholders' equity, and cash
flows for the year then ended, together with the notes thereto, audited by and
accompanied by the report of Ernst & Young LLP, independent accountants; and

The Company Financial Statements were prepared in accordance with generally
accepted accounting principles in effect in the United States ("GAAP") applied
on a consistent basis during the periods involved (except (i) as may be
indicated in the notes thereto, (ii)  in the case of the unaudited financial
statements, such differences in presentation or omissions as permitted by Rule
10-01 of Regulation S-X of the SEC and (iii) the unaudited financial statements
do not contain all notes required by GAAP) and fairly present in accordance with
applicable requirements of GAAP (subject, in the case of the unaudited financial

Pro Forma Financial Statements fairly present the information shown therein and
the assumptions and adjustments relating thereto are reasonable and have been

Registration Statement on Form S-4 to be filed with the SEC by Parent in

statement of a material fact or omit to state any material fact required to be

the circumstances under which they are made, not misleading.  If at any time
prior to the Effective Time any event with respect to the Company or any of its
Subsidiaries, or with respect to other information supplied by the Company for
inclusion in the Proxy Statement or S-4, shall occur which is required to be
described in an amendment of, or a supplement to, the Proxy Statement or the S-
4, such event shall be so described, and such amendment or supplement shall be
promptly filed with the SEC and, as required by law, disseminated to the
stockholders of Parent.  The S-4 and the Proxy Statement, insofar as they relate
to the Company or its Subsidiaries or other information supplied by the Company
for inclusion therein, will comply as to form in all material respects with the
provisions of the Securities Act and the Securities Exchange Act of 1934, as

     (d) Authority; No Violations; Consents and Approvals.

          (i) The Board of Directors of Parent has unanimously declared as
advisable and fair to and in the best interests of the stockholders of Parent

increase the number of authorized shares of Parent Common Stock to 60,000,000
(the "Charter Amendment") and the issuance (the "Parent Share Issuance") of
shares of Parent Common Stock in accordance with the Merger and the Subscription
Agreement and has unanimously approved this Agreement.  Parent has all requisite
power and authority to enter into this Agreement and, subject to approval of the
Charter Amendment and the Parent Share Issuance, to consummate the transactions
contemplated hereby.  Upon Sub's formation, Sub will have requisite power and
authority to enter into this Agreement and to consummate the transactions

consummation by Parent and Sub of the transactions contemplated hereby have been
duly authorized by all necessary corporate action on the part of Parent and Sub,
subject to approval of the Charter Amendment and the Parent Share Issuance by a
majority of outstanding Parent Common Stock entitled to vote thereon at the
Parent Stockholder Meeting and subject to certain actions with respect to Sub
which Parent will take prior to Closing.  This Agreement has been duly executed
and delivered by Parent, on behalf of itself and Sub, and subject, with respect
to the consummation of the Merger, to stockholder approval of the Charter
Amendment and the Parent Share Issuance, and assuming this Agreement constitutes
the valid and binding obligation of the Company, constitutes a valid and binding
obligation of Parent and will constitute a valid and binding obligation of Sub,
in each case enforceable in accordance with its terms, subject, as to
enforceability, to bankruptcy, insolvency, reorganization and other laws of
general applicability relating to or affecting creditors' rights and to general
principles of equity.

          (ii) Except as set forth on Schedule 3.2(d) of the Parent Letter, the
execution and delivery of this Agreement does not, and the consummation of the
transactions contemplated hereby and compliance with the provisions hereof will
not, conflict with, or result in any violation of, or default (with or without
notice or lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or to the loss of a material
benefit under, or result in the creation of any lien, security interest, charge
or encumbrance upon any of the properties or assets of Parent or any of its
Subsidiaries under, any provision of (i) the Certificate of Incorporation or
Bylaws of Parent or any provision of the comparable charter or organizational
documents of any of its Subsidiaries, (ii) any loan or credit agreement, note,
bond, mortgage, or indenture applicable to Parent or

other than, in the case of clause (iii), any such conflicts, violations,
defaults, rights, liens, security interests, charges or encumbrances that,

Effect, materially impair the ability of Parent to perform its obligations
hereunder or prevent the consummation of any of the transactions contemplated
hereby.

          (iii) No consent, approval, order or authorization of, or
registration, declaration or filing with, or permit from any Governmental Entity
is required by or with respect to Parent or any of its Subsidiaries in
connection with the execution and delivery of this Agreement by Parent and Sub
or the consummation by Parent and Sub of the transactions contemplated hereby,

Effect, except for: (A) the filing of a premerger notification report by Parent
under the HSR Act, and the expiration or termination of the applicable waiting

<PAGE>

commitment or failure to act that would cause Parent or any such Subsidiary to
fail to comply with such covenants and agreements; or (vi) any other action,
transaction, commitment, dispute or other event or condition (financial or

industries of Parent or any of its Subsidiaries generally.

     (h) No Undisclosed Material Liabilities.  Except as fully reflected or
reserved against in the financial statements included in the Parent SEC

"Parent Representatives") to, directly or indirectly, solicit or initiate any
prospective buyer or the making of any proposal that constitutes, or may
reasonably be expected to lead to, a Parent Acquisition Proposal (as defined
herein) from any person; provided, however, that, notwithstanding any other
provision of this Agreement, (i) Parent may engage in discussions or
negotiations with a third party who (without any solicitation or initiation,
directly or indirectly, by or with Parent or any Parent Representatives after
the date of this Agreement) seeks to initiate such discussions or negotiations
and may furnish such third party information concerning Parent and its business,

Directors after consultation with Parent's financial advisors), the Board of
Directors of Parent may withdraw, modify or not make its recommendation referred
to in Section 5.5 or terminate this Agreement in accordance with Section 7.1(b),
but in each case referred to in the foregoing clauses (i) through (iii) only to
the extent that the Board of Directors of Parent shall conclude in good faith
that such action is necessary in order for the Board of Directors of Parent to
act in a manner that is consistent with its fiduciary obligations under
applicable law.  Parent shall immediately cease and cause to be terminated any
existing solicitation, initiation, encouragement, activity, discussion or
negotiation with any parties conducted heretofore by Parent or any Parent
Representatives with respect to any Parent Acquisition Proposal existing on the
date hereof.  Parent will promptly notify the Company of any such requests for
such information or the receipt of any Parent Acquisition Proposal, including
the identity of the person or group engaging in such discussions or
negotiations, requesting such information or making such Parent Acquisition
Proposal, and (unless the Board of Directors of Parent concludes such disclosure
is

                                     -60-
<PAGE>
 
inconsistent with its fiduciary obligations under applicable law) the material

or exchange offer, a merger, consolidation or other business combination
involving Parent or any Significant Subsidiary of Parent or any proposal to
acquire in any manner a substantial equity interest in, or substantially all of
the assets of, Parent or any of its Significant Subsidiaries.

                             ADDITIONAL AGREEMENTS
                                        
     5.1  Preparation of S-4 and the Proxy Statement.  Parent shall promptly
prepare and file with the SEC the Proxy Statement and the S-4, in which the
Proxy Statement will be included as a prospectus.  Parent shall use its
reasonable best efforts to have the S-4 declared effective under the Securities
Act as promptly as practicable after such filing.  Parent shall use its
reasonable best efforts to cause the Proxy Statement to be mailed to
stockholders of Parent at the earliest practicable date.  Parent shall use its

reasonable best efforts to cause to be delivered to Parent a letter of KPMG Peat
Marwick LLP, the Company's independent public accountants, and Ernst & Young
LLP, Sweco's independent public accountants, each dated a date within two
business days before the date on which the S-4 shall become effective and

efforts to cause a letter of Ernst & Young LLP, Parent's independent public

delivered by independent public accountants in connection with registration

entities as is customary for similar letters.

     5.4  Access to Information.  Upon reasonable notice, the Company and
Parent shall each (and shall cause each of their respective Subsidiaries to)
afford to the officers, employees, accountants, counsel and other
representatives of the other, access, during normal business hours during the
period prior to the Effective Time, to all its properties, books, 

                                     -61-
<PAGE>
 
contracts, commitments and records and, during such period, each of the Company
and Parent shall (and shall cause each of their respective Subsidiaries to)
furnish promptly to the other (a) a copy of each quarterly, annual or current
report on Form 10-Q, 10-K or 8-K, schedule, registration statement and other
document filed or received by it during such period pursuant to SEC requirements
and (b) all other information concerning its business, properties and personnel

contemplated by this Agreement. The Confidentiality Agreement dated as of
October 24, 1995 between Parent and Drexel Oilfield Services Inc. (the

     5.6  Legal Conditions to Merger.  Each of the Company, Parent and Sub will
take all reasonable actions necessary to comply promptly with all legal
requirements that may be imposed on such party with respect to the Merger
(including, without limitation, furnishing all information required under the
HSR Act and in connection with approvals of or filings with any other
Governmental Entity) and will promptly cooperate with and furnish information to
each other in connection with any such requirements imposed upon any of them or
any of their Subsidiaries in connection with the Merger.  Each of the Company,
Parent and Sub will, and will cause its Subsidiaries to, take all actions
necessary to obtain (and will cooperate with each other in obtaining) any
consent, acquiescence, authorization, order or approval of, or any exemption or
nonopposition by, any Governmental Entity, court or other person or entity,

Parent or any of their Subsidiaries in

                                     -62-
<PAGE>
 
connection with the Merger or the taking of any action contemplated thereby or
by this Agreement, including complying with any requests or orders made by the
Justice Department or the Federal Trade Commission in connection with the
Merger.

     5.7  Agreements of Others.  Prior to the Effective Time, the Company shall
cause to be prepared and delivered to Parent a list identifying all persons who,
at the time of the Company Stockholder Meeting, may be deemed to be "affiliates"
of the Company as that term is used in paragraphs (c) and (d) of Rule 145 under
the Securities Act (the "Affiliates").  The Company shall use its reasonable
best efforts to cause each person who is identified as an Affiliate in such list
to deliver to Parent, at or prior to the Effective Time, a written agreement, in
a form mutually agreeable to the Company and Parent whereby each such person
acknowledges that such person is subject to the provisions of Rule 145(d)
promulgated under the Securities Act.

     5.8  Listing.  Parent shall use its reasonable best efforts to cause the
shares of Parent Common Stock to be issued in the Merger, the shares of Parent
Common Stock issuable upon exercise of the Warrants and the shares of Parent
Common Stock issuable upon exercise of the Company Stock Options and issuable
under the Company Stock Option Plans to be approved for trading on the Nasdaq
Stock Market or the New York Stock Exchange, Inc. (the "NYSE"), subject to
official notice of issuance, prior to the Closing Date.

     5.9  Board of Directors and Officers at the Effective Time.  Parent shall
take all necessary  action so that as of the Effective Time the directors of
Parent shall only be those individuals identified as directors on Exhibit C-1
hereto and the officers of Parent shall only be those individuals identified as
officers on Exhibit C-2 hereto, except to the extent any such individual is
unwilling or unable to serve in such capacity.  Parent represents and warrants
to the Company that it has received irrevocable letters of resignation effective
as of the Effective Time from all of the current directors of Parent other than
individuals identified as directors on Exhibit C-1 hereto.  If prior to the
Effective Time an individual identified on Exhibits C-1 or C-2 hereto as a
director or officer is unwilling or unable to serve in such capacity, then the
directors of Parent specified on Exhibit C-1 that are willing and able to serve
shall fill any vacancies promptly after the Effective Time.

     5.10 Stock Options; Reservation and Registration of Shares.  (a) At the
Effective Time, each outstanding option to purchase the Company Common Stock and
any stock appreciation rights related thereto that have been granted pursuant to
the Company Stock Option Plans (a " Company Stock Option"), whether vested or
unvested, shall be assumed by Parent.  Each such option shall be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such Company Stock Option, a number of shares of Parent Common
Stock equal to the number of shares of  Company Common Stock purchasable
pursuant to such Company Stock Option multiplied by the Stock Option Exchange
Ratio (as hereinafter defined), at a price per share equal to the per-share
exercise price for the shares of Company Common Stock purchasable pursuant to
such Company Stock Option divided by the Stock Option Exchange Ratio; provided,
however, that in the case of any option to which Section 421 of the Code applies
by reason of its qualification under any of Sections 422-424 of the Code, the
option price, the number of shares purchasable pursuant to such option and the
terms and conditions of exercise of such option

                                     -63-
<PAGE>
 
shall be determined in order to comply with Section 424(a) of the Code; and
provided further, that the number of shares of Parent Common Stock that may be
purchased upon exercise of such Company Stock Option shall not include any
fractional share and, upon exercise of such Company Stock Option, a cash payment
shall be made for any fractional share based upon the closing price of a share
of Parent Common Stock on the Nasdaq Stock Market or, if then traded on an
exchange, such exchange, on the last trading day of the calendar month
immediately preceding the date of exercise. "Stock Option Exchange Ratio" shall
mean initially .4372, which amount shall be increased as of the date that
Escrowed Shares are distributed pursuant to the Escrow Agreement by (i) the
product of .0273 multiplied by (ii) the quotient of the number of Escrowed
Shares distributed to former holders of Company Common Stock divided by the
aggregate number of Escrowed Shares. Notwithstanding the foregoing, (i) if a
Company Stock Option is exercised prior to the date that Escrowed Shares are
distributed pursuant to the Escrow Agreement, upon such date appropriate
adjustments shall be made so that such optionee will be in the same position
with respect to Parent Common Stock as if the Stock Option Exchange Ratio on the
date of such exercise had been the adjusted Stock Option Exchange Ratio as of
such date and (ii) the Company may elect prior to the Effective Time to cancel
for cash consideration the Sweco Options in accordance with their terms.

     (b) Subject to the approval of the Charter Amendment, Parent shall take all
corporate action necessary to reserve for issuance a sufficient number of shares
of Parent Common Stock for delivery upon exercise of the Company Stock Options.
As soon as practicable after the Effective Time, Parent shall file with the SEC
a registration statement on Form S-8 (or any successor form) or another
appropriate form with respect to the shares of Parent Common Stock subject to
the Company Stock Options and shall use its best efforts to maintain the
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as the Company Stock Options remain outstanding.

     5.11 Indemnification; Directors' and Officers' Insurance.  (a) From and
after the Effective Time, Parent and the Surviving Corporation shall indemnify,
defend and hold harmless each person who is now, or has been at any time prior
to the date hereof or who becomes prior to the Effective Time, an officer or
director of the Parent or the Company or any of their Subsidiaries or an
employee of the Parent or the Company or any of their Subsidiaries who acts as a
fiduciary under any of the Parent Benefit Programs, the Parent Plans, the
Company Benefit Programs or the Company Plans (the "Indemnified Parties")
against all losses, claims, damages, costs, expenses (including attorneys'
fees), liabilities or judgments or amounts that are paid in settlement with the
approval of the indemnifying party (which approval shall not be unreasonably
withheld) of or in connection with any threatened or actual claim, action, suit,
proceeding or investigation based in whole or in part on or arising in whole or
in part out of the fact that such person is or was a director, officer, or such
employee of the Parent or the Company or any of their Subsidiaries whether
pertaining to any matter existing or occurring at or prior to the Effective Time
and whether asserted or claimed prior to, or at or after, the Effective Time
("Indemnified Liabilities"), including all Indemnified Liabilities based in
whole or in part on, or arising in whole or in part out of, or pertaining to
this Agreement or the transactions contemplated hereby, in each case to the
fullest extent permitted under applicable law (and Parent and the Surviving
Corporation, as

                                     -64-
<PAGE>
 
the case may be, will pay expenses in advance of the final disposition of any
such action or proceeding to each Indemnified Party to the fullest extent
permitted by law). Without limiting the foregoing, in the event any such claim,
action, suit, proceeding or investigation is brought against any Indemnified
Parties (whether arising before or after the Effective Time), (i) the
Indemnified Parties may retain counsel satisfactory to them, Parent and the
Surviving Corporation and Parent and the Surviving Corporation shall pay all
fees and expenses of such counsel for the Indemnified Parties promptly as
statements therefor are received; and (ii) the Parent and the Surviving
Corporation will use all reasonable efforts to assist in the vigorous defense of
any such matter, provided that neither the Parent nor the Surviving Corporation
shall be liable for any settlement effected without its written consent, which
consent, however, shall not be unreasonably withheld. Any Indemnified Party
wishing to claim indemnification under this Section 5.11, upon learning of any
such claim, action, suit, proceeding or investigation, shall notify the Parent
and the Surviving Corporation, but the failure so to notify shall not relieve a
party from any liability that it may have under this Section 5.11, except to the
extent such failure materially prejudices such party. The Indemnified Parties as
a group may retain only one law firm to represent them with respect to each such
matter unless there is, under applicable standards of professional conduct, a
conflict on any significant issue between the positions of any two or more
Indemnified Parties. The Company, Parent and Sub agree that all rights to
indemnification, including provisions relating to advances of expenses incurred
in defense of any action or suit, existing in favor of the Indemnified Parties
(including in the Memorandum of Association or Bye-laws or in the
indemnification agreements previously provided by Parent to the Company) with
respect to matters occurring through the Effective Time, shall survive the
Merger and shall continue in full force and effect for a period of six years
from the Effective Time; provided, however, that all rights to indemnification
in respect of any Indemnified Liabilities asserted or made within such period
shall continue until the disposition of such Indemnified Liabilities.

     (b) For a period of six years after the Effective Time, if Parent maintains
directors' and officers' liability insurance with respect to matters arising
after the Effective Time, then Parent shall cause to be maintained in effect the
current policies of directors' and officers' liability insurance maintained by
the Company and its Subsidiaries or other policies of comparable coverage and
amounts with respect to matters arising before the Effective Time covering the
Indemnified Parties, provided that Parent shall not be required to pay an annual
premium for such insurance to the extent Parent's Board of Directors considers
such premium unreasonable provided that, in such case, Parent shall purchase as
much coverage, if any, as Parent's Board of Directors determines may be
reasonably purchased.

     5.12 Registration Rights.  At the Closing, the Company agrees to execute
and deliver the Registration Rights Agreement in the form of Exhibit D hereto.

     5.13 Public Announcements.  Parent and Sub, on the one hand, and the
Company, on the other hand, will consult with each other before issuing any
press release or otherwise making any public statements with respect to the
transactions contemplated by this Agreement, and shall not issue any such press
release or make any such public statement prior to such consultation, except as
may be required by applicable law or by obligations

                                     -65-
<PAGE>
 
pursuant to any listing agreement with any national securities exchange or
transaction reporting system.

     5.14 Other Actions.  Except as contemplated by this Agreement, neither
Parent nor the Company shall, and shall not permit any of its Subsidiaries to,
take or agree or commit to take any action that is reasonably likely to result
in any of its respective representations or warranties hereunder being untrue in
any material respect or in any of the conditions to the Merger set forth in
Article VI not being satisfied.  Upon the terms and subject to the conditions
set forth in this Agreement, each of the parties hereto agrees to use its
reasonable best efforts to take or cause to be taken, all actions, and to do, or
cause to be done, and to assist and cooperate with the other parties in doing,
all things necessary, proper or advisable, to consummate and make effective, in
the most expeditious manner practicable, the Merger and the other transactions
contemplated by this Agreement.

     5.15 Advice of Changes; SEC Filings.  Parent and the Company shall confer
on a regular basis with each other, report on operational matters and promptly
advise each other orally and in writing of any change or event having, or which,
insofar as can reasonably be foreseen, could have, a Parent Material Adverse
Effect or Company Material Adverse Effect.  The Company and Parent shall
promptly provide each other (or their respective counsel) copies of all filings
made by such party with the SEC or any other state or federal Governmental
Entity in connection with this Agreement and the transactions contemplated
hereby.

     5.16 Reorganization. It is the intention of Parent and the Company that
the Merger and the Liquidation collectively will qualify as a reorganization
described in Section 368(a) of the Code (and any comparable provisions of
applicable state or local law).  Neither Parent nor the Company (nor any of
their respective Subsidiaries) will take or omit to take any action (whether
before, on or after the Closing Date) that would cause the Merger and the
Liquidation collectively not to be so treated.  The parties will characterize
the Merger and the Liquidation collectively as such a reorganization for
purposes of all Returns and other filings.

     5.17 Change of Control.  Parent and the Company agree that the
transactions contemplated by this Agreement shall constitute a "Change of
Control" as defined in the executive employment agreements of Parent listed on
Schedule 5.17 of the Parent Letter.  Parent represents and warrants to the
Company that true and complete copies of such executive employment agreements
have been delivered to the Company prior to the date hereof under cover letter
specifically identifying such agreements as those listed on Schedule 5.17.

     5.18 Certain Tax Agreements.  At or before the Closing, the Company will
(i) provide to Parent copies of one or more duly executed statements described
in Treasury Regulation Section 1.897-2(h)(1), which are issued by each of the
Company's directly owned Subsidiaries that is organized in the United States or
is organized outside the United States for which an election under Section
897(i) of the Code is in effect and which are dated not more than 30 days before
the Closing Date, certifying that the stock of each such Subsidiary

                                     -66-
<PAGE>
 
is not a United States real property interest and (ii) cause any such Subsidiary
to provide to the IRS a duly executed notice described in Treasury Regulation
Section 1.897-2(h)(2).

     5.19 Formation of Sub.  Parent agrees to promptly cause Sub to be formed
and to ratify and approve this Agreement.  Parent agrees to be responsible for,
and to cause Sub to comply with, Sub's obligations hereunder.

                                   ARTICLE VI
                                        
                              CONDITIONS PRECEDENT

outstanding shares of the Company Common Stock entitled to vote thereon at the
Company Stockholder Meeting, and the Parent Share Issuance and the Charter
Amendment shall have been approved by the holders of a majority of the
outstanding shares of Parent Common Stock entitled to vote thereon at the Parent

shares of Parent Common Stock required to be reserved for issuance in connection
with the Merger shall have been authorized for trading on the Nasdaq Stock
Market or, listing on the NYSE, upon official notice of issuance.

     (c) Other Approvals.  The waiting period applicable to the consummation of
the Merger under the HSR Act shall have expired or been terminated and all
filings required to be made prior to the Effective Time with, and all consents,
approvals, permits and authorizations required to be obtained prior to the
Effective Time from any Governmental Entity and from any necessary parties to
Parent's Credit Facility and the Company's Credit Facility in connection with
the execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby by the Company, Parent and Sub shall have been
made or obtained (as the case may be), except where the failure to obtain such
consents, approvals, permits, and authorizations would not be reasonably likely
to result in a Parent Material Adverse Effect (assuming the Merger and the
Liquidation have taken place) or to materially adversely affect the consummation
of the Merger or the Liquidation.

     2.   Appointment of Escrow Agent.  Parent and the Company hereby designate
          ---------------------------                                          
and appoint _____________________ as Escrow Agent for the purposes set forth
herein and the Escrow Agent hereby accepts such appointment on the terms herein
provided.

     3.   Deposit of Escrowed Shares.  Promptly after the Effective Time, Parent
          --------------------------                                            
shall deliver to the Escrow Agent one or more certificates in the name of the
Escrow Agent representing the Escrowed Shares and cash in lieu of any fractional
shares.

     4.   Maintenance of Escrow.
          --------------------- 

          (a) The Escrow Agent shall hold the Escrowed Shares in escrow, and
     shall maintain and disburse the Escrowed Shares, pursuant to this Escrow
     Agreement.

          (b) All dividends and other distributions of money, securities or
     other property made by Parent with respect to the Escrowed Shares while
     such shares are held by the Escrow Agent, shall be paid or delivered to the
     Stockholders pro rata in accordance with their respective ownership of
     Company Common Stock immediately prior to the Effective Time, at the same
     time such dividends or other distributions are paid or delivered to other
     holders of Parent Common Stock; provided, however, that there shall be paid
     or delivered to the Escrow Agent at such time all shares of Parent Common
     Stock issuable as a result of any stock dividend or stock split with
     respect to the Escrowed Shares.  The Escrowed Shares and such additional
     shares of Parent 

                                     -79-
<PAGE>
 
     Common Stock are collectively referred to in this Escrow Agreement as the
     "Escrow Funds."

     5.   Parent's Right to Assert Claim to Escrow Funds.  Parent shall have the
          ----------------------------------------------                        
right to make one Claim on or prior to the Claim Expiration Time by delivering a
written notice of such Claim to the Stockholders Representative and the Escrow
Agent prior to such time.  Subject to the other provisions herein, Parent shall
have the right to receive a portion or all of the Escrow Funds only if the
Damages for such Claim (determined without giving effect to the individual
materiality thresholds contained in Section 3.1 of the Merger Agreement when
evaluating the Damages resulting from a Breach, but without duplication for the
same Damages resulting from more than one Breach) exceed the Threshold Amount
and then only in the amount by which such Damages exceed $1,000,000.  If Parent
asserts a Claim, such Claim shall state with particularity all Breaches
asserted, including sufficient facts relating thereto so that the Stockholders
Representative may reasonably evaluate such Claim, the aggregate Damages
incurred by Parent, Parent's estimate of the Threshold Amount and the amount
(the "Parent Net Claim") that equals (i) the aggregate amount of such Damages,
less (ii) $1,000,000, rounded to the nearest amount evenly divisible by $7.00.
Notwithstanding anything to the contrary herein, Parent shall in no event be
entitled to receive pursuant to this Agreement, more than the then available
Escrow Funds.  The parties agree that the $1,000,000 deductible set forth above
was a negotiated risk sharing provision and does not and was not intended to,
reflect either party's understanding or agreement as to the level of Damages
necessary to exceed the Threshold Amount or constitute a Company Material
Adverse Effect.

     6.   Determination of Valid Parent Net Claim; Final Instruction.  For
          ----------------------------------------------------------      
purposes of this Escrow Agreement, a "Final Instruction" shall mean a written
notice given to the Escrow Agent directing the disbursement of the amount of the
Parent Net Claim, and shall be signed both by Parent and by the Stockholders
Representative except as otherwise provided below in clause (b) or (d).  A Final
Instruction shall be delivered to the Escrow Agent under the following
circumstances, and accompanied by the indicated documentation:

          (a) If the Stockholders Representative disputes either the validity,
     amount or calculation of the Threshold Amount or the Parent Net Claim, the
     Stockholders Representative shall give written notice of such dispute to
     Parent, with a copy to the Escrow Agent, within 20 business days after the
     delivery of notice of the Claim by Parent.  In such circumstances, no Final
     Instruction may be given to the Escrow Agent except as provided in (c) or
     (d) below.

          (b) If the Stockholders Representative fails to respond to the Claim
     within 20 business days after the delivery to the Stockholders
     Representative and the Escrow Agent of the Notice of the Claim, or if the
     Stockholders Representative notifies the Escrow Agent that there is no
     dispute with respect to the Parent Net Claim, Parent 

                                     -80-
<PAGE>
 
     shall have the right to deliver to the Escrow Agent a Final Instruction,
     signed only by Parent, with respect to the Parent Net Claim.

          (c) If the Stockholders Representative and Parent reach an agreement
     with respect to the proper determination of the Threshold Amount or the
     Parent Net Claim, the Stockholders Representative and Parent shall give to
     the Escrow Agent a Final Instruction, signed by both the Stockholders
     Representative and Parent, with respect to the Parent Net Claim.

          (d) If an arbitration order pursuant to Section 22 hereof, is entered
     with respect to the Parent Net Claim, either the Stockholders
     Representative or Parent shall have the right to deliver to the Escrow
     Agent a Final Instruction with respect to the Parent Net Claim based on and
     in compliance with such order, signed only by the Stockholders
     Representative or by Parent, as the case may be, and accompanied by a copy
     of such order.

     Upon receipt of a Final Instruction in accordance with this Section, the
Escrow Agent shall disburse to Parent from the Escrow Funds such number of
shares of Parent Common Stock as shall equal the Parent Net Claim based on the
valuation procedures set forth in Section 8 herein and shall distribute the
remaining Escrow Funds in accordance with Section 7 below.

     7.   Distribution of Escrow Funds.  If Parent fails to make a Claim on or
          ----------------------------                                        
prior to the Claim Expiration Time in accordance with Section 5, then as
promptly as practicable thereafter the Escrow Agent shall deliver the Escrowed
Shares and all other Escrow Funds to the Stockholders pro rata in accordance
with their respective ownership of Company Common Stock immediately prior to the
Effective Time.  If Parent timely makes a Claim, then upon the Escrow Agent's
receipt of a Final Instruction, the Escrow Agent shall deliver such portion of
the Escrow Funds to Parent as set forth in such Final Instruction and then shall
deliver any remaining Escrowed Shares and any other remaining Escrow Funds, on a
pro rata basis, to the Stockholders.

     8.   Valuation of Escrowed Shares; Fractional Shares.  For purposes of
          -----------------------------------------------                  
determining the number of Escrowed Shares to be disbursed from the Escrow Fund
under this Escrow Agreement with respect to the Parent Net Claim, each share of
Parent Common Stock shall be valued at $7.00 per share (subject to appropriate
adjustment for any stock split, stock dividend, reverse stock split or similar
event with respect to Parent Common Stock effected after the Effective Time),
regardless of the then market value of such shares.  No certificates or scrip
representing fractional shares of Parent Common Stock shall be issued pursuant
to this Agreement.  In lieu of any fractional share of Parent Common Stock, each
Stockholder who would otherwise have been entitled to a fraction of a share of
Parent Common Stock hereunder shall be paid an amount in cash (without interest)
equal to the value of such fraction of a share based upon an assumed value of
$7.00 per share (subject to 

                                     -81-
<PAGE>
 
appropriate adjustment for any stock split, stock dividend, reverse stock split
or similar event with respect to Parent Common Stock effected after the
Effective Time). Parent agrees to pay to Escrow Agent such amounts as are
necessary to pay such cash in lieu of fractional shares and the Escrow Agent
shall transfer and deliver such shares to Parent with respect to which cash is
so paid as a result of the distribution to the Stockholders.

     9.   Reliance by Escrow Agent; Liability of Escrow Agent.  The Escrow Agent
          ---------------------------------------------------                   
shall be protected in acting upon any written notice, request, waiver, consent,
certificate, receipt, authorization or other paper or document that the Escrow
Agent believes to be genuine and what it purports to be.  The Escrow Agent may
confer with its own corporate or outside legal counsel in the event of any
dispute or question as to the construction of any of the provisions hereof, or
its duties hereunder, and shall incur no liability and shall be fully protected
in acting in accordance with the written opinions of such counsel.  The duties

pursuant to the provisions of this Escrow Agreement that it reasonably believes
to be genuine and in conformity with the requirements of this Escrow Agreement.
The Escrow Agent undertakes to use the same degree of care and skill in
performing its services hereunder as an ordinary prudent person would do or use
under the circumstances in the conduct of his or her own affairs.  The Escrow
Agent will not be liable for any action taken or not taken by it under the terms
hereof in the absence of breach of its obligations hereunder or gross negligence
or willful misconduct on its part.

     10.  Indemnification of Escrow Agent.  Parent will indemnify and hold the
          -------------------------------                                     
Escrow Agent harmless from and against any and all losses, costs, damages or
expenses (including, but not limited to, reasonable attorneys' fees) it may

in respect of such Stockholder's shares of Company Common Stock and by becoming
a beneficiary of this Escrow Agreement, releases the Stockholder Representative
from liability for any action taken or not taken by the Stockholders

successor is appointed within 30 days, then Parent shall appoint an independent
third party as successor.

to fulfill the duties of the Escrow Agent hereunder for the remaining term of

     Section 2.  Registration Rights.
                ------------------- 

     2.1  Piggyback Registration.
          ---------------------- 

          (a) If the Company proposes to file a registration statement under the
1933 Act with respect to an offering by the Company for its own account or for
the account of any other Person of Common Stock (excluding, however, a security
convertible into Common Stock) then the Company shall in each case give written
notice of such proposed filing to the Holders of Registrable Securities at least
fifteen days before the anticipated filing date, and such notice shall offer
such Holders the opportunity to register such number of Registrable Securities
as each such Holder may request (a "Piggyback Registration"). Subject to
subsections (b), (c), (d) and (e) of this Section 2.1, the Company shall include
in each such Piggyback Registration all Registrable Securities requested to be
included in the registration for such offering. The Company shall cause the
managing underwriter or underwriters of a proposed underwritten offering to
permit the Holders of Registrable Securities requesting to be included in the
registration for such offering to include such securities in such offering on
the same terms and conditions as Common Stock of the Company included therein.
Notwithstanding the foregoing, if the managing underwriter or underwriters of
such offering determines that the total amount of securities which they or the
Company and any other Persons intend to include in such offering may jeopardize
the success of such offering, then the amount of securities to be offered shall
be reduced first from the Common Stock being offered for the account of Persons
(other than Holders and the Company) entitled to include Common Stock in such
offering and whose rights to include Common Stock in the offering rank
subordinate to the rights of the Holders of Registrable Securities and then, if
the offering size shall require further reduction, from the Common Stock being
offered for the account of the Holders of Registrable Securities and such other
Persons entitled to include Common Stock in such offering and whose rights to
include such Common Stock rank pari passu to the registration rights of the
                               ----------                                  
Holders (allocated pro rata in proportion to their respective number of shares
to be registered) to the extent necessary to reduce the total amount of
securities to be included in such offering to the amount recommended by such
managing underwriter or underwriters prior to any reduction of the securities to
be sold by the Company.

                                     -93-
<PAGE>
 
          (b)  Notwithstanding anything to the contrary contained in this
     Agreement, the Company shall not be required to include Registrable
     Securities in any registration statement on Forms S-4 or S-8 (or their
     successor forms) or if the proposed registration is (i) a registration of a
     stock option or other employee incentive compensation plan or of securities
     issued or issuable pursuant to any such plan, (ii) a registration of
     securities issued or issuable pursuant to a stockholder reinvestment plan
     or other similar plan, or (iii) a registration of securities issued in
     exchange for any securities or any assets of, or in connection with a
     merger or consolidation with, an unaffiliated company.

         (c)  The Company may withdraw any registration statement and abandon
    any proposed offering initiated by the Company without the consent of any
    Holder of Registrable Securities, notwithstanding the request of any such
    Holder to participate therein in accordance with this provision, if the
    Company determines in its sole discretion that such action is in the best
    interests of the Company and its stockholders (for this purpose, the
    interest of the Holders shall not be considered).

    2.2   Demand Registration Rights.
          -------------------------- 

     (a)    From and after the first anniversary of the effective date of this
Agreement, subject to the conditions stated hereinafter in this Section 2.2,
each Requisite Group may make one written request to the Company for
registration with the Commission of the offer and sale of all or part of the
Registrable Securities held by Holders in such Requisite Group under and in
accordance with the provisions of the 1933 Act (each a "Demand Registration");
provided, that the estimated proceeds (based on the market value of Common Stock
- --------                                                                        
as of the date of such request) of the Registrable Securities proposed to be
sold by the Holder or Holders in the Requisite Group shall exceed $10,000,000.
Within 5 Business Days after receipt of such request, the Company will serve
written notice (the "Demand Notice") of such registration request to all Holders
of Registrable Securities and the Company will include in such registration all
such Registrable Securities with respect to which the Company has received
written requests for inclusion therein within 7 Business Days after the receipt
by the applicable Holder of the Demand Notice.

     (b)    Subject to the provisions of Section 2.2(c), each Requisite Group
shall be entitled to one Demand Registration (which must become effective under
the 1933 Act to count as having occurred) with respect to its Registrable
Securities; provided, however, that in no event shall the Company be required to
            --------                                                            
effect more than one Demand Registration in any twelve month period.  A
registration will not count as a Demand Registration until it has become
effective unless (i) the Holders of the Registrable Securities to be included
therein advise the Company that they do not intend to complete the sale of the
Registrable Securities covered by such registration statement or (ii) such
Holders have otherwise abandoned the offering covered by such registration
statement for any reason other than (A) the inability or unreasonable delay of
the Company in having such registration statement become effective or (B) the
disclosure of material adverse information regarding the Company that was not
known by such Holders at the time the request for such Demand Registration was
made; 

                                     -94-
<PAGE>
 
provided, further, that if such registration statement is otherwise
abandoned by such Holders prior to the registration statement becoming effective
and if there has been a material decline in the market price of Company Common
Stock from the time of such request to such abandonment, then such Demand
Registration shall not count as a Demand Registration if the Holders promptly
reimburse the Company for all Registration Expenses (as defined herein) other
than the Company's internal expenses.

     (c)    If the managing underwriter or underwriters of a Demand Registration
(or in the case of a Demand Registration not being underwritten, the Holders of
a majority of the Registrable Securities being registered therein), advise the
Company in writing that in its or their opinion that the total number of
Registrable Securities proposed to be sold in such Demand Registration exceeds
the number which can be sold in such offering at the desired price, the Company
will include in such registration only the number of Registrable Securities
which, in the opinion of such underwriter or underwriters (or Holders, as the
case may be) can be sold, allocated pro rata among the Holders of Registrable
Securities that have requested to be included in such Demand Registration on the
basis of the amount of Registrable Securities requested to be registered by each
such Holder.

     (d)  If any Demand Registration is an underwritten offering, the Holders of
a majority of the Registrable Securities to be included in such Demand
Registration will select a managing underwriter or underwriters acceptable to
the Company to administer the offering, which acceptance will not be
unreasonably withheld or delayed.

     (e)  Notwithstanding the provisions of Sections 2.2(a)-(d), the Company
shall not be obligated to effect a registration requested pursuant to Sections
2.2(a)-(d) if (i) within 10 days after receiving the notice provided by any
Holder under Sections 2.2(a)-(d), the Company notifies all Holders of
Registrable Securities of its intention to file a registration statement for an
underwritten public offering of Common Stock for the sole account of the Company
and within twenty days after providing such notice, the Company files a
registration statement for such offering and (ii) the Company has never before
exercised its rights under this Section 2.2(e).  In such case, the Holders shall
have all the rights provided herein as if no such Demand Registration had been
requested.  If at any time the Company fails to diligently pursue any such
registration statement or offering, the provisions of the preceding sentence
shall not apply, and the Company shall be obligated to satisfy its obligations
under Sections 2.2(a)-(d).  With respect to such Company registration, the
Company shall have the sole authority to select or terminate the employment of
underwriters, and to make all decisions in connection with the filing,
effectiveness and consummation of the proposed offering, subject to the express
provisions hereof.

     (f)  Notwithstanding the obligations of the Company under Sections 2.2(a)-
(d), the Company shall be entitled to postpone for a reasonable period of time
(not exceeding 90 days) the filing (but not the preparation) of any registration
statement otherwise required to be prepared and filed by it pursuant hereto if
(i) at the time the Company receives a request for such registration, the
Company is in possession of 

                                     -95-
<PAGE>
 
material non-public information that would be required to be disclosed in a
registration statement but that has not been and will otherwise not be disclosed
to the public and the Company deems disclosure not to be in the best interests
of the Company and its stockholders (and the Company so notifies the Holders
requesting a Demand Registration within 5 Business Days of such request), or
(ii) the Company determines (and the Company so notifies the Holders requesting
a Demand Registration within 5 Business Days of such request) that in its
judgment, such registration and offering would materially interfere with any
financing, acquisition, corporate reorganization or other material transaction
involving the Company that prior to such request the Board of Directors of the
Company had agreed by resolution to pursue.

2.3  Holdback Agreements; Requirements of Holders.
     -------------------------------------------- 

     (a)  To the extent not inconsistent with applicable law, each Holder of
Registrable Securities owning Registrable Securities that are included in a
registration statement that registers Registrable Securities pursuant to this
Agreement or who is given the option pursuant to the terms hereof to include
Registrable Securities in a registration statement that registers Registrable
Securities agrees not to effect any public sale or distribution of the issue
being registered (or any securities of the Company convertible into or
exchangeable or exercisable for securities of the same type as the issue being
registered) during the 10 days prior to, and during the 90-day period beginning
on, the effective date of a registration statement filed by the Company (except
pursuant to such registration), but only if and to the extent requested in
writing (with reasonable prior notice) by the managing underwriter or
underwriters in the case of an underwritten public offering by the Company of
securities of the same type as the Registrable Securities; provided, that  the
period of time for which the Company is required to keep such registration
statement which includes Registrable Securities continuously effective shall be
increased by a period equal to such requested holdback period.

     (b)  The Company agrees not to effect any public sale or distribution of
any securities similar to those being registered, or any securities convertible
into or exchangeable or exercisable for such securities, except on Form S-8 (or
its successor form), during the 10 days prior to, and during the 90-day period
beginning on, the effective date of any Demand Registration in which the Holders
of Registrable Securities are participating (except pursuant to such
registration statement).

     (c)  The offering of Registrable Securities by any Holder shall comply in
all respects with the applicable terms, provisions and requirements set forth in
this Agreement, and such holder shall timely provide the Company with all
information and materials required to be included in a registration statement
that (a) relate to the offering, (b) are in possession of such Holder, and (c)
relate to such Holder, and to take all such action as may be reasonably required
in order not to delay the registration and offering of the securities by the
Company.

     2.4  Registration Procedures.  Whenever any Registrable Securities are to
          -----------------------                                             
be registered pursuant to Sections 2.1 or 2.2 of this Agreement, the Company
shall effect the registration of such Registrable Securities in accordance with
the intended method of disposition thereof as quickly as practicable.  In
connection with any Piggyback Registration or Demand Registration, the Company
shall as expeditiously as possible:

     (a)  prepare and file with the Commission a registration statement which
includes the Registrable Securities and make every reasonable effort to cause
such registration statement to become effective; provided, that before filing a
registration statement or prospectus or any amendments or supplements thereto,
including documents incorporated by reference after the initial filing of the
registration statement, the Company will furnish to one counsel selected by the
Holders of a majority of the Registrable Securities covered by such registration
statement and the underwriters, if any, draft copies of all such documents
containing material changes from previously filed documents proposed to be filed
at least 2 Business Days prior thereto, which documents will be subject to the
reasonable review of such Holders and underwriters, and the Company will not
file any registration statement or amendment thereto or any prospectus or any
supplement thereto (including such documents incorporated by reference) to which
Holders of a majority of the Registrable Securities covered by such registration
statement or the underwriters with respect to such Registrable Securities, if
any, shall reasonably object, and will notify each Holder of the Registrable
Securities of any stop order issued or threatened by the Commission in
connection therewith and take all reasonable actions required to prevent the
entry of such stop order or to remove it if entered;

     (b)  prepare and file with the Commission such amendments and post-
effective amendments to the registration statement as may be necessary to keep
the registration statement effective for a period of not less than 60 days (or
such shorter period which will terminate when all Registrable Securities covered
by such registration statement have been sold or withdrawn or such longer period
as required pursuant to the applicable underwriting agreement); cause the
prospectus to be supplemented by any required prospectus supplement, and as so
supplemented to be filed pursuant to Rule 424 under the 1933 Act; and to the
extent of its control comply with the provisions of the 1933 Act applicable to
it with respect to the disposition of all securities covered by such
registration statement during the applicable period in accordance with the
intended methods of disposition by the sellers thereof set forth in such
registration statement or supplement to the prospectus; the Company shall not be
deemed to have complied with its obligations hereunder to keep a registration
statement effective during the applicable period if it voluntarily takes any
action that would result in selling Holders of the Registrable Securities being
prevented from selling such Registrable Securities during the period unless such
action is required under applicable law;

     (c)  furnish to any Holder of Registrable Securities included in such
registration statement and the underwriter or underwriters, if any, without
charge, such number of conformed copies of the registration statement and any
post-effective amendment thereto and such number of copies of the prospectus
(including each 

                                     -97-
<PAGE>
 
preliminary prospectus) and any amendments or supplements thereto, and any
documents incorporated by reference therein, as such Holder or underwriter may
reasonably request in order to facilitate the disposition of the Registrable
Securities being sold by such Holder (it being understood that the Company
consents to the use of the prospectus and any amendment or supplement thereto by
each Holder of Registrable Securities covered by the registration statement and
the underwriter or underwriters, if any, in connection with the offering and
sale of the Registrable Securities covered by the prospectus or any amendment or
supplement thereto); provided, that before filing a registration statement or
prospectus or any amendments or supplements thereto, the Company will furnish to
one counsel selected by the Holders of a majority of the Registrable Securities
covered by such registration statement copies of all documents proposed to be
filed which documents will be subject to the review of such counsel;

     (d)  notify each Holder of Registrable Securities included in such
registration statement, at any time when a prospectus relating thereto is
required to be delivered under the 1933 Act, when the Company becomes aware of
the happening of any event as a result of which the prospectus included in such
registration statement (as then in effect) contains any untrue statement of a
material act or omits to state a material fact necessary to make the statements
therein (in the case of the prospectus or any preliminary prospectus, in light
of the circumstances under which they were made) not misleading and, as promptly
as practicable thereafter, prepare and file with the Commission and furnish a
supplement or amendment to such prospectus so that, as thereafter delivered to
the purchasers of such Registrable Securities, such prospectus will not contain
any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading;

     (e)  cause all Registrable Securities included in such registration
statement to be listed, by the date of the first sale of Registrable Securities
pursuant to such registration statement, on each securities exchange (including,
for this purpose, NASDAQ) on which the Common Stock of the Company is then
listed or proposed to be listed, if any;

     (f)  make generally available to its security holders an earnings statement
satisfying the provisions of Section 11(a) of the 1933 Act no later than 45 days
after the end of the 12-month period beginning with the first day of the
Company's first fiscal quarter commencing after the effective date of the
registration statement, which earnings statement shall cover said 12-month
period, which requirement will be deemed to be satisfied if the Company timely
files complete and accurate information on Forms 10-Q, 10-K and 8-K under the
Exchange Act and otherwise complies with Rule 158 under the 1933 Act as soon as
feasible;

     (g)  make every reasonable effort to obtain the withdrawal of any order
suspending the effectiveness of the registration statement at the earliest
possible moment;

                                     -98-
<PAGE>
 
     (h)  if requested by the managing underwriter or underwriters or any Holder
of Registrable Securities covered by the registration statement, promptly
incorporate in a prospectus supplement or post-effective amendment such
information as the managing underwriter or underwriters or such Holder
reasonably requests to be included therein, including, without limitation, with
respect to the number of Registrable Securities being sold by such Holder to
such underwriter or underwriters, the purchase price being paid therefor by such
underwriter or underwriters and any other terms of the underwritten offering of
such Registrable Securities, and promptly make all required filings of such
prospectus supplement or post-effective amendment;

     (i)  as promptly as practicable after filing with the Commission of any
document which is incorporated by reference into a registration statement,
deliver a copy of such document to each Holder of Registrable Securities covered
by such registration statement;

     (j)  on or prior to the date on which the registration statement is
declared effective, use reasonable diligence to register or qualify, and
cooperate with the Holders of Registrable Securities included in such
registration statement, the underwriter or underwriters, if any, and their
counsel, in connection with the registration or qualification of the Registrable
Securities covered by the registration statement for offer and sale under the
securities or blue sky laws of each state and other jurisdiction of the United
States as any such Holder or underwriter reasonably requests in writing, to use
reasonable diligence to keep each such registration or qualification effective,
including through new filings, or amendments or renewals, during the period such
registration statement is required to be kept effective and to do any and all
other acts or things necessary or advisable to enable the disposition in all
such jurisdictions of the Registrable Securities covered by the applicable
registration statement; provided, that the Company will not be required to
qualify generally to do business in any jurisdiction where it is not then so
qualified or to take any action which would subject it to general service of
process in any such jurisdiction where it is not then so subject;

     (k)  cooperate with the Holders of Registrable Securities covered by the
registration statement and the managing underwriter or underwriters, if any, to
facilitate the timely preparation and delivery of certificates (not bearing any
restrictive legends) representing securities to be sold under the registration
statement, and enable such securities to be in such denominations and registered
in such names as the managing underwriter or underwriters, if any, or such
Holders may request, subject to the underwriters' obligation to return any
certificates representing securities not sold;

     (l)  cause the Registrable Securities covered by the registration statement
to be registered with or approved by such other governmental agencies or
authorities within the United States as may be necessary to enable the seller or
sellers thereof or the underwriter or underwriters, if any, to consummate the
disposition of such securities;

                                     -99-
<PAGE>
 
     (m)  enter into such customary agreements (including an underwriting
agreement in customary form) and take all such other reasonable actions as the
Holders of a majority of the Registrable Securities being sold or the
underwriters retained by Holders participating in an underwritten public
offering, if any, reasonably request in order to expedite or facilitate the
disposition of such Registrable Securities;

     (n)  make available for inspection by any Holder of Registrable Securities
included in such registration statement, any underwriter participating in any
disposition pursuant to such registration statement, and any attorney,
accountant or other agent retained by any such seller or underwriter
(collectively, the "Inspectors"), all financial and other records, pertinent
corporate documents and properties of the Company (collectively, the "Records"),
as shall be reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all Records reasonably requested by any such Inspector in connection with
such registration statement; provided, that with respect to any Records that are
confidential, the Inspectors shall execute such confidentiality agreements as
the Company may reasonably request in order to maintain the confidentiality of
confidential Records; and

     (o)  obtain a "cold comfort" letter from the Company's independent public
accountants in customary form and covering such matters of the type customarily
covered by cold comfort letters as the Holders of a majority of the Registrable
Securities being sold reasonably request.

     Each Holder, upon receipt of any notice from the Company of the happening
of any event of the kind described in subsection (d) of this Section 2.4, will
forthwith discontinue disposition of the Registrable Securities until such
Holder's receipt of the copies of the supplemented or amended prospectus
contemplated by subsection (d) of this Section 2.4 or until it is advised in
writing (the "Advice") by the Company that the use of the prospectus may be
resumed, and has received copies of any additional or supplemental filings which
are incorporated by reference in the prospectus, and, if so directed by the
Company, such Holder will, or will request the managing underwriter or
underwriters, if any, to, deliver to the Company (at the Company's expense) all
copies in their possession or control, other than permanent file copies then in
such Holder's possession, of the prospectus covering such Registrable Securities
current at the time of receipt of such notice.  In the event the Company shall
give any such notice, the time periods mentioned in subsection (b) of this
Section 2.4 shall be extended by the number of days during the period from and
including the date of the giving of such notice to and including the date when
such seller of Registrable Securities covered by such registration statement
shall have received the copies of the supplemented or amended prospectus
contemplated by subsection (d) of this Section 2.4 hereof or the Advice.

     If such registration statement refers to any Holder by name or otherwise as
the holder of any securities of the Company then such Holder shall have the
right to require (i) the insertion therein of language, in form and substance
satisfactory to such Holder, to the effect that the holding by such Holder of
such securities is not to be construed as a recommendation of such Holder of the
investment quality of the Company's securities covered thereby and 

                                     -100-
<PAGE>
 
that such holding does not imply that such Holder will assist in meeting any
future financial requirements of the Company, or (ii) in the event that such
reference to such Holder by name or otherwise is not required by the Securities
Act or any similar federal statute then in force, the deletion of the reference
to such Holder.

     2.5  Registration Expenses.  All expenses incident to the Company's
          ---------------------                                         
performance of or compliance with this Agreement, including without limitation,
all Commission and securities exchange or National Association of Securities
Dealers, Inc. registration and filing fees, fees and expenses (other than the
pro rata portion of filing fees attributable, as required by state law, to the
securities to be sold) of compliance with securities or blue sky laws (including
fees and disbursements of counsel in connection with blue sky qualifications of
the Registrable Securities), printing expenses, messenger and delivery expenses,
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), the fees and
expenses incurred in connection with the listing of the securities to be
registered on each securities exchange on which similar securities issued by the
Company are then listed and fees and disbursements of counsel for the Company
and its independent certified public accountants (including the expenses of any
special audit or "cold comfort" letters required by or incident to such
performance), securities act liability insurance (if the Company elects to
obtain such insurance), the fees and expenses of any special experts retained by
the Company in connection with such registration (but not including any
underwriting fees, discounts or commissions attributable to the sale of
Registrable Securities), the reasonable fees and expenses of a single counsel to
represent participating Holders in a Demand Registration (all such expenses
being herein called "Registration Expenses"), will be borne by the Company.

     2.6  Indemnification and Contribution.
          -------------------------------- 

          (a) The Company agrees to indemnify and hold harmless each Holder of
Registrable Securities, its officers, directors and each Person who controls
such Holder (within the meaning of the 1933 Act), and any Agent (as hereinafter
defined) or investment advisor thereof against all losses, claims, damages,
liabilities and expenses (including reasonable costs of investigation)
(collectively, "Liabilities") arising out of or based upon any untrue or alleged
untrue statement of material fact contained in any registration statement, any
amendment or supplement thereto, any prospectus or preliminary prospectus  or
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as any such Liabilities arise out of or are based upon any untrue
statement or omission based upon information with respect to such indemnified
Person furnished in writing to the Company by such indemnified Person expressly
for use therein.  Notwithstanding the foregoing, with respect to any untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact in a preliminary prospectus, the indemnity agreement of
the Company in this Section 2.6(a) shall not inure to the benefit of any Holder
of Registrable Securities, underwriter or their respective control persons or
Agents on account of any loss, claim, damage, liability or action arising from
the sale of the Registrable Securities to any Person if the underwriter failed
to give or send a copy of the final prospectus, as the same may be supplemented
or amended, to that Person 

                                     -101-
<PAGE>
 
within the time required by the 1933 Act, and the untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact in such preliminary prospectus was corrected in such final prospectus. In
connection with an underwritten offering, the Company will indemnify the
underwriters thereof, their officers and directors and each Person who controls
such underwriters (within the meaning of the 1933 Act) to the same extent as
provided above with respect to the indemnification of the Holders of Registrable
Securities or to such other extent as the Company and such underwriters may
agree. For purposes of this Section 2.6(a), an "Agent" of a Holder of
Registrable Securities is any Person acting for or on behalf of such Holder with
respect to the holding or sale of such Registrable Securities.

     (b)  In connection with any registration statement in which a Holder of
Registrable Securities is participating, each such Holder will furnish to the
Company in writing such information with respect to the name and address of such
Holder and the amount of Registrable Securities held by such Holder and such
other information as the Company shall reasonably request for use in connection
with any such registration statement or prospectus, and agrees to indemnify to
the extent permitted by law, the Company, its directors and officers and each
Person who controls the Company (within the meaning of the 1933 Act) against any
losses, claims, damages, liabilities and expenses resulting from any untrue
statement of a material fact or any omission of a material fact required to be
stated in the registration statement or prospectus or any amendment thereof or
supplement thereto or necessary to make the statements therein no misleading, to
the extent, but only to the extent, that such untrue statement or omission is
based upon any information with respect to such Holder so furnished in writing
by such Holder specifically for inclusion in any prospectus or registration
statement.  In no event shall the liability of any selling Holder or Registrable
Securities hereunder be greater in amount than the dollar amount of the proceeds
received by such Holder upon the sale of the Registrable Securities giving rise
to such indemnification obligation.

     (c)  Any Person entitled to indemnification hereunder agrees to give prompt
written notice to the indemnifying party after the receipt by such Person of any
written notice of the commencement of any action, suit, proceeding or
investigation or threat thereof made in writing for which such Person may claim
indemnification or contribution pursuant to this Agreement and, unless in the
written opinion of counsel for such indemnified party a conflict of interest may
exist between such indemnified party and the indemnifying party with respect to
such claim, permit the indemnifying party to assume the defense of such claim
with counsel reasonably satisfactory to such indemnified party.  Whether or not
such defense is assumed by the indemnifying party, the indemnifying party will
not be subject to any liability for any settlement made without its consent.  No
indemnifying party will 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 of such claim or litigation.  If the indemnifying party is
not entitled to, or elects not to, assume the defense of a claim, it will not be
obligated to pay the fees and expenses of more than one counsel with respect to
such claim.

                                     -102-
<PAGE>
 
     (d)  If the indemnification provided for in this Section 2.6 from the
indemnifying party is unavailable to an indemnified party hereunder in respect
of any losses, claims, damages, liabilities or expenses referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages, liabilities or expenses in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party and indemnified parties in connection with the actions which resulted in
such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations.  The relative fault of such indemnifying
party and indemnified parties shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact, has been made by, or relates to information
supplied by, such indemnifying party or indemnified parties, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such action.  The amount paid or payable by a party as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include, subject to the limitations set forth in Section 2.6(c), any
legal or other fees or expenses reasonably incurred by such party in connection
with any investigation or proceeding.

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 2.6(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 2.6(d), no selling Holder shall
be required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities of such selling Holder were offered to
the public exceeds the amount of any damages which such selling Holder has
otherwise been required to pay by reason of such untrue statement or omission.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation.

     2.7    No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's securities on the terms of and on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements (which shall be the Company in the case of an offering of
securities by the Company) and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements.

     2.8    The Company covenants that it will file the reports required to be
filed by it under the 1933 Act and the Exchange Act and the rules and
regulations adopted by the Commission thereunder (or, if the Company is not
required to file such reports, it will, upon the request of any holder of
Registrable Securities, make publicly available other nonconfidential
information so long as necessary to permit sales under Rule 144 under the 1933
Act), and it will take such action as any Holder of Registrable Securities may
reasonably request, all to the extent required from time to time to enable such
Holder to sell Registrable Securities without registration under the 1933 Act
within the limitation of the 

                                     -103-
<PAGE>
 
exemptions provided by (a) Rule 144 under the 1933 Act, as such Rule may be
amended from time to time, or (b) any similar rule or regulation hereafter
adopted by the Commission. Upon the request of any Holder of Registrable
Securities, the Company will deliver to such Holder a written statement as to
whether it has complied with such requirements.

     Section 3  Other Registration Rights.
                ------------------------- 

     3.1  Future Rights.  After the date of this Agreement, the Company will not
          -------------                                                         
grant to any Person (including the Holders of Registrable Securities) any
registration rights ("new rights") with respect to any securities of the Company
without the written consent of the Holders of a majority of the then outstanding
Registrable Securities unless such new rights (i) are subordinate to and of a
lesser priority than the registration rights granted by the Company under this
Agreement and (ii) are not inconsistent with the terms of this Agreement.
Additionally, unless otherwise consented to in writing by the Holders of a
majority of the then outstanding Registrable Securities, new rights may not be
granted without expressly providing that, with respect to demand registration
rights granted to such other Persons, the Holders of Registrable Securities have
a piggyback right upon the exercise of such new rights and shall be included in
any related registration statement on the same terms and conditions as the
holders of the new rights, subject to possible reduction at the initiative of
the managing underwriter or underwriters, on terms substantially equivalent to
those set forth in Section 2.1.  The Company may grant registration rights that
permit any Person the right to piggyback or may itself exercise the right to
piggyback on any Demand Registration; provided, that if the managing underwriter
or underwriters of such offering determines that the total amount of securities
which they and the holders of such new piggyback rights intend to include in any
offering may jeopardize the success of such offering (including the price at
which such securities can be sold), then the amount or kind of securities to be
offered for the account of holders of such new piggyback rights, or the Company
if it is exercising piggyback rights, will be reduced to the extent necessary to
reduce the total amount of securities to be included in such offering to the
amount recommended by the managing underwriter prior to any reduction in the
amount of Registrable Securities to be included; and further provided, that if
such offering is not underwritten, then any such piggyback right shall be
exercised only with the consent of the Holders of a majority of the Registrable
Securities being offered.

     3.2    Representation and Warranty.  The Company hereby represents and
          ---------------------------                                    
warrants to the Holders that on or prior to the date hereof, (a) the Company has
not granted any outstanding registration rights to any Person except for the
registration rights granted under this Agreement and the Outstanding
Registration Rights Agreements and (b) no consent, approval, authorization or
waiver of any Person is required to permit the Company to execute or deliver
this Agreement or perform this Agreement in accordance with its terms.

     Section 4  Miscellaneous.
                ------------- 

     4.1  Recapitalizations, Exchange, etc.  The provisions of this Agreement
          ---------------------------------                                  
shall apply, to the full extent set forth herein with respect to the Registrable
Securities, to any and all shares of equity capital of the Company or any
successor or assign of the Company 

                                     -104-
<PAGE>
 
(whether by merger, consolidation, sale of assets or otherwise) which may be
issued in respect of, in exchange for, or in substitution of the Registrable
Securities, in each case as the amounts of such securities outstanding are
appropriately adjusted for any equity dividends, splits, reverse splits,
combinations, recapitalizations and the like occurring after the date of this
Agreement.

     4.2  Opinions.  When any legal opinion is required to be delivered
          --------                                                     
hereunder, such opinion may contain such qualifications as may be customary or
otherwise appropriate for legal opinions in similar circumstances.

     4.3  Notices.  For purposes of this Agreement, notices and all other
          -------

such other address as any party may furnish to the others in writing in
accordance herewith, except that notices of changes of address shall be
effective only upon receipt, and that failure to copy  legal counsel shall not
invalidate notices otherwise properly given.

     4.4  Applicable Law.  This contract is entered into under, and shall be
          --------------                                                    
governed for all purposes by, the laws of the State of Texas without regard to
principles of conflicts of laws.

     4.5  Amendment and Waiver.  This Agreement may be amended, and the
          --------------------                                         
provisions hereof may be waived, only by a written instrument signed by (i) the
Holders of a majority of the then outstanding Registrable Securities, and (ii)
the Company; provided, however, that in no event shall any amendment impose any
additional material obligations on any Holder without such Holder's written
consent.  No failure by either party hereto at any time to give notice of any
breach by the other party of, or to require compliance with, any condition or
provision of this Agreement shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.

     4.6  Remedy for Breach of Contract.  The parties agree that in the event
          -----------------------------                                      
there is any breach or asserted breach of the terms, covenants or conditions of
this Agreement, the remedy of the parties hereto shall be in law and in equity
and injunctive relief shall lie for the enforcement of or relief from any
provisions of this Agreement.  If any remedy or relief is sought and obtained by
any party against one of the other parties pursuant to this Section 4.6, the
other party shall, in addition to the remedy of relief so obtained, be liable to
the party seeking such remedy or relief for the reasonable expenses incurred by
such 

                                     -105-

party in successfully obtaining such remedy or relief, including the fees
and expenses of such party's counsel.

     4.7  Severability.  If any term, provision, covenant or restriction of this
          ------------                                                          
Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall in
no way be affected, impaired or invalidated, and the parties hereto shall use
their best efforts to find and employ an alternative means to achieve the same
or substantially the same result as that contemplated by such term, provision,
covenant or restriction.  It is hereby stipulated and declared to be the
intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such which may
be hereafter declared invalid, void or unenforceable.

     4.8  Entire Agreement.  This Agreement is intended by the parties as a
          ----------------                                                 
final expression of their agreement and is intended to be a complete and
exclusive statement of the agreement and understanding of the parties hereto in
respect of the subject matter contained herein.  There are no restrictions,
promises, warranties nor undertakings, other than those set forth or referred to
herein with respect to the registration rights granted by the Company with
respect to the Registrable Securities.  This Agreement supersedes all prior
agreements and understandings between the parties with respect to such subject
matter.

     4.9  Successors and Assigns.  This Agreement shall inure to the benefit of
          ----------------------

assigned to any person who acquires Registrable Securities from a Holder, except
that any person who acquires such Registrable Securities (x) pursuant to a
public offering registered under the 1933 Act, or (y) pursuant to a transfer
made in accordance with Rule 144 under the 1933 Act (or any similar successor
provision) may not be assigned rights hereunder with respect to such Registrable
Securities.  Notwithstanding the foregoing, rights to cause a demand
registration under Section 2.2 may only be assigned if such rights are expressly
assigned in writing from a Holder.  Any assignment of registration rights
pursuant to this Section 4.10 shall be effective upon receipt by the Company of
written notice from such assigning Holder (i) stating the name and address of
any assignee, (ii) describing the manner in which the assignee acquired the
Registrable Securities from such Holder and (iii) identifying the number of
Registrable Securities with respect to which the rights under this Agreement are
being assigned.

own any Registrable Securities or Warrants, (ii) the first such instance after
the second anniversary of the Effective Time as such Holder ceases to own at
least five percent of the outstanding shares 

                                     -106-

                                   OF PARENT

and authority to enter into this Agreement and the capacity and authority to
make the representations, warranties, covenants and agreements herein. The
execution, delivery and performance by Parent of this Agreement have been duly

the rights provided for therein, such shares will be validly issued, fully paid
and non-assessable, and the issuance of such shares will not be subject to any

     execution and delivery of this Agreement by Parent or its performance of
     the terms hereof, including without limitation, the issuance and sale of
     the Shares and the Warrants, or the validity or enforceability hereof or
     thereof against Parent as to which the failure to obtain or make would have
     a Parent Material Adverse Effect or would materially adversely affect the

     Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and
     the expiration or termination of the applicable waiting period with respect
     thereto.

           (b) The execution and delivery of this Agreement does not, and the
     consummation of the transactions contemplated hereby and compliance with
     the provisions hereof will not, conflict with, or result in any violation
     of, or default (with or without notice or lapse of time, or both) under, or
     give rise to a right of termination, cancellation or acceleration of any
     obligation or to the loss of a material benefit under, or result in the

     made and the approval of the Merger and the Charter Amendment and the
     Parent Share Issuance by the stockholders of Parent has been obtained, any
     judgment, order, decree, statute, law, ordinance, rule or regulation
     applicable to Parent or any of its Subsidiaries or any of their respective
     properties or assets, other than, in the case of clause (iii), any such
     conflicts, violations, defaults, rights, liens, security interests, charges
     or encumbrances that, individually or in the aggregate, would not have a
     Parent Material Adverse Effect, materially impair the ability of Parent to
     perform its obligations hereunder or prevent the consummation of any of the
     transactions contemplated hereby.

     (ii) the Purchaser shall have performed in all material respects all
     covenants required of it by this Agreement as of the Closing Date and (iii)
     the Purchaser shall have furnished Parent at the Closing with a certificate
     of one of its authorized representatives to such effect.

           (b) Payment of Purchase Price.  The Purchaser shall have paid the
     purchase price for the Securities to be paid at the Closing as specified in
     Section 1.1 hereof.

     to the consummation of the Merger as set forth in Sections 6.1 (other than

     waived by a party having the right to waive such condition under the Merger
     Agreement, as of the Closing Date.

     12.1  Headings.  The descriptive headings of the several Articles and
Sections of this Agreement are inserted for convenience only and do not
constitute a part of the Agreement.

     12.2  Entire Agreement.  This Agreement, the documents to be executed
hereunder, and the exhibits attached hereto constitute the entire agreement
between the parties hereto pertaining to the subject matter hereof and supersede
all prior agreements, understandings, negotiations and discussions, whether oral
or written, of the parties pertaining to the subject matter hereof.

     12.3  Waiver.  At any time prior to the Closing, any party hereto may (a)
extend the time for the performance of any of the obligations or other acts of
any other party hereto or (b) waive compliance with any of the agreements of any
other party or with any conditions to its own obligations. Any agreement on the
part of a party hereto to any such extension or waiver shall be valid if set
forth in an instrument in writing signed on behalf of such party. The
consummation of the transactions contemplated hereby shall not be deemed a
waiver of the right any party may have hereunder with respect to any other
party's representations, warranties, covenants or agreements contained in or
related to this Agreement being incorrect, untrue or breached.

     12.4  Amendment.  This Agreement may not be amended except by an instrument
in writing signed by each of the parties hereto.  No supplement, alteration or
modification of this Agreement shall be binding unless executed in writing by
the parties hereto.

     12.5  Further Actions. Each party shall execute and deliver such other
certificates, agreements and other documents and take such other actions as may
reasonably be requested by the other parties in order to consummate or implement
the transactions contemplated by this Agreement.

     12.6  Assignment. Except as otherwise expressly provided herein,  the terms
and conditions of this Agreement shall inure to the benefit of and be binding
upon the respective successors and assigns of Parent and the Purchaser.  Parent
may not assign or delegate any of its rights or duties hereunder, without the
prior written consent of the Purchaser.  Purchaser may not assign or delegate
any of its rights or duties hereunder without the prior written consent of
Parent, which consent shall not be unreasonably withheld; but in any event
Purchaser shall remain responsible for any assignee's performance.  Any
assignment or delegation made without such consent shall be void.

     12.7  Independent Covenants.  The covenants contained herein are
independent and separate, and in the event that any provision contained herein
is declared invalid or illegal, the other provisions hereof shall not be
affected or impaired thereby and shall remain valid and enforceable.

     12.8  Remedies and Certain Rights.  In the event of a breach or threatened
breach by any party hereto of the provisions of this Agreement, any other party
hereto shall be entitled to specific performance.  The parties agree that, from
and after the Closing, regardless of whether the Shares and the Warrants have
been registered under the Securities Act of 1933, as amended, if Parent breaches
a representation made in Section 3.5, then Purchaser shall be entitled to and
shall have under this Agreement all rights, remedies and recourse against Parent
that Purchaser would have had if Purchaser had acquired the Securities pursuant
to the S-4, had relied upon such S-4 to make its investment decision and had not
entered into this Agreement (i.e. Purchaser shall have contractual rights
hereunder that are equivalent to the rights that a purchaser of securities
pursuant to a registration statement would have); it being acknowledged that
Purchaser is entering into this Agreement in reliance upon the expected actions
of persons and entities assuming the representations in Section 3.5 will be
true.

     12.9  Governing Law.  This Agreement and the other documents delivered
pursuant hereto and the legal relations between the parties shall be governed
and construed in accordance with the laws of the State of Delaware, without
giving effect to principles of conflict of laws.

     12.10 Counterparts.  This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed an original but all
of which together shall constitute one and the same instrument.

     12.11 Withholding or Granting of Consent.  Except as otherwise provided in
this Agreement, each party hereto may, with respect to any consent or approval
that it is entitled to grant pursuant to this Agreement or any other document or
instrument or agreement delivered or entered into pursuant hereto, grant or
withhold such consent or approval in its sole and uncontrolled discretion, with
or without cause, and subject to such conditions as it shall deem appropriate.

     12.12 Notices.  Any notice or communication required or permitted hereunder
shall be in writing and either delivered personally, telegraphed or telecopied
or sent by certified or registered mail, postage prepaid, and shall be deemed to
be given, dated and received when so delivered personally, telegraphed or
telecopied or, if mailed, five business days after the date of mailing to the
following address or telecopy number, or to such other address or addresses as
such person may subsequently designate by notice given hereunder.

               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK
                           EXPIRING DECEMBER 31, 2000
                                        
NO. 1                                                           2,533,000 SHARES


     BY THIS WARRANT (this "Warrant"), Tuboscope Vetco International
Corporation, a Delaware corporation (the "Company"), certifies that, for good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, SCF III, L.P., a Delaware limited partnership (along with its
registered assigns, the "Holder"), is entitled to subscribe for and purchase
from the Company, subject to the terms and conditions set forth herein, at any
time or from time to time prior to 5:00 p.m. (Houston, Texas time) on December
31, 2000 (the "Expiration Date") 2,533,000 (subject to adjustment as set forth
herein) fully paid and non-assessable shares (the "Shares") of the Company's
Common Stock, $0.01 par value per share (the "Common Stock"), at a price equal
to the exercise price per share, initially $10.00 (subject to adjustment as set
forth herein) per share (the "Exercise Price").

     1.   Exercise of Warrant; Company Office.  This Warrant may be exercised at
          -----------------------------------                                   
any time or from time to time prior to the Expiration Date  as to the entire
number or any lesser number of whole shares of Common Stock, by the surrender of
this Warrant to the Company at its office at 2835 Holmes Road Houston, Texas
77051, or such other place as is designated in writing by the Company pursuant
to this Section 1, together with (a) a duly executed election in substantially
the form of Exhibit A attached hereto and made a part hereof for all purposes,
            ---------                                                         
and (b)  a wire transfer or a certified or bank cashier's check payable to the
order of the Company in an amount equal to the Exercise Price multiplied by the
number of shares of Common Stock covered by such election.  Notwithstanding the
foregoing sentence, at any time that the Current Market Price (as hereinafter
defined) is greater than the Exercise Price, the Holder may, at its option,
exercise this Warrant at any time or from time to time prior to the Expiration
Date as to the entire number or any lesser number of whole shares of Common
Stock, by the surrender of this Warrant to the Company at the location
designated in the foregoing sentence together with a duly executed election in
substantially the form of Exhibit A attached hereto and made a part hereof for
                          ---------                                           
all purposes and, in return therefor, the Company shall deliver to the Holder
that certain number of shares of Common Stock that is determined by dividing
(aa) the product of (1) the number of shares of Common Stock covered by such
election and (2) the difference between the Current Market Price at the date of
such exercise and the Exercise Price in effect on the date of such exercise by
(bb) the Current Market Price at the date of such exercise.  For so long as this
Warrant is outstanding, the Company shall continue to maintain an office in the
State of Texas where notices, presentations and demands in respect of this
Warrant may be made upon it and shall notify the Holder in writing at least 15
days before changing the location of any such office.

     2.   Stock Ownership; Stock Certificates; Partial Exercise.  Upon each
          -----------------------------------------------------            
exercise of this Warrant, the Holder shall be deemed to be the holder of record
of the shares of Common Stock issuable upon such exercise as of the close of
business on the day this 

                                     -122-
<PAGE>
 
Warrant is exercised, notwithstanding that the stock transfer books of the
Company shall then be closed or certificates representing such shares shall not
then have been actually delivered to the Holder. As soon as possible after each
such exercise of this Warrant, the Company shall issue and deliver to the Holder
a certificate or certificates for the shares issuable upon such exercise issued
in such denominations as may be specified by Holder and registered in the name
of the Holder or, subject to Section 9, such other name or names as shall be
designated in the Holder's election to exercise. If this Warrant should be
exercised in part only, the Company shall, upon surrender of this Warrant for
cancellation, execute and deliver a new Warrant evidencing the right of the
Holder to purchase the balance of the shares subject to purchase hereunder on
the terms and conditions set forth herein (including all changes and adjustments
that have occurred hereunder). The Company will, at the time of each exercise of
this Warrant, upon the request of the Holder hereof, acknowledge in writing its
continuing obligation to afford to such Holder all rights to which such Holder
shall continue to be entitled after such exercise in accordance with the terms
of this Warrant; provided, however, that if the Holder of this Warrant shall
                 --------
fail to make any such request, such failure shall not affect the continuing
obligation of the Company to afford such rights to such Holder.

     3.   Company Records; Transfer or Assignment of Warrant; Exchange of
          ---------------------------------------------------------------
Warrant.  Any warrants issued in connection herewith or in substitution herefor,
- -------                                                                         
upon complete or partial transfer, assignment or exercise (the "Warrants") shall
be numbered and shall be registered in the warrant register of the Company (the
"Warrant Register") as they are issued.  The Company shall treat the registered
holder of any Warrant on the Warrant Register as the owner in fact thereof for
all purposes, except that if the Warrant is properly transferred or assigned and
notice of such transfer or assignment is given to the Company, the Company shall
treat the transferee or assignee as the owner thereof for all purposes (or, if
such transfer or assignment is properly made in blank, the Company shall treat
the bearer of this Warrant as the owner thereof for all purposes).  The Warrant
shall be transferred by the Company upon delivery thereof duly endorsed by the
Holder or by his duly authorized attorney or representative, or accompanied by
proper evidence of succession, assignment or authority to transfer.  In case of
transfer by executors, administrators, guardians or other legal representatives,
duly authenticated evidence of their authority shall be produced if requested by
the Company in its reasonable discretion.  The Company shall immediately
register all assignments and transfers in the Warrant Register and, upon any
registration of assignment or transfer, the Company shall deliver a new Warrant
or Warrants to the person or entity entitled thereto on the terms and conditions
set forth herein (including all changes and adjustments that have occurred
hereunder).  A Warrant, if properly transferred or assigned, may be exercised by
a subsequent Holder without having a new Warrant issued.  The Warrants may be
exchanged at the option of the Holder thereof for another Warrant, or other
Warrants, of different denominations and representing in the aggregate the right
to purchase the same number of shares of Common Stock on the terms and
conditions set forth herein (including all changes and adjustments that have
occurred hereunder) upon surrender to the Company or its duly authorized agent.
All provisions of this Section 3 shall be subject to Section 9.

     4.   Reserved Stock.  The Company shall reserve and keep available at all
          --------------                                                      
times solely for the purpose of providing for the exercise of this Warrant the
maximum number of shares of Common Stock as to which this Warrant may then be
exercised.  All such shares 

                                     -123-
<PAGE>
 
shall be duly authorized and free of preemptive rights and, when issued upon
such exercise, shall be validly issued, fully paid and non-assessable.

     5.   Certain Adjustments.
          ------------------- 

     (a) Number of Shares; Exercise Price.  The number of shares of Common Stock
         --------------------------------                                       
which the Holder of this Warrant shall be entitled to receive upon each exercise
hereof shall be determined by multiplying the number of shares of Common Stock
which would otherwise (but for the provisions of this Section 5) be issuable
upon such exercise, as designated by the Holder hereof, by a fraction of which
(a) the numerator is $10.00 and (b) the denominator is the Exercise Price in
effect on the date of such exercise.  The Exercise Price shall be adjusted and
readjusted from time to time as provided in this Section 5 and, as so adjusted
or readjusted, shall remain in effect until a further adjustment or readjustment
thereof is required by this Section 5.

     (b) Issuance of Additional Shares of Common Stock or Certain Convertible
         --------------------------------------------------------------------
Securities.  If on or after the date hereof the Company shall issue any Common
- ----------                                                                    
Stock other than Excluded Stock (as hereinafter defined) without consideration
or for a consideration per share less than the Current Market Price in effect
immediately prior to such issuance, the Exercise Price in effect immediately
prior to each such issuance shall immediately (except as otherwise expressly
provided below) be reduced to the price determined by dividing (1) an amount
equal to the sum of (A) the number of shares of Common Stock outstanding
immediately prior to such issuance multiplied by the Current Market Price in
effect immediately prior to such issuance and (B) the consideration, if any,
received by the Company upon such issuance, by (2) the total number of shares of
Common Stock outstanding immediately after such issuance.

          For the purposes of any adjustment of the Exercise Price pursuant to
     this Section 5(b), the following provisions shall be applicable:

          (A) Cash.  In the case of the issuance of Common Stock for cash, the
              ----                                                            
     amount of the consideration received by the Company shall be deemed to be
     the amount of the cash proceeds received by the Company for such Common
     Stock before deducting therefrom any discounts, commissions, taxes or other
     expenses allowed, paid or incurred by the Company for any underwriting or
     otherwise in connection with the issuance and sale thereof.

          (B) Consideration Other Than Cash.  In the case of the issuance of
              -----------------------------                                 
     Common Stock (otherwise than upon the conversion of shares of capital stock
     or other securities of the Company) for a consideration in whole or in part
     other than cash, including securities acquired in exchange therefor (other
     than securities of the Company that by their terms are exchangeable for
     such Common Stock), the consideration other than cash shall be deemed to be
     the fair value thereof as determined in good faith by the Board of
     Directors of the Company and irrespective of any accounting treatment;
     provided, that such fair value as determined by the Board of Directors
     --------                                                              
     shall not exceed the aggregate Current Market Price of the shares of Common
     Stock being issued as of the date on which the Board of Directors
     authorizes the issuance of such shares.

                                     -124-
<PAGE>
 
          (C) Options and Convertible Securities.  In the case of the issuance
              ----------------------------------                              
     of (i) options, warrants or other rights to purchase or acquire Common
     Stock (whether or not at the time exercisable), (ii) securities by their
     terms convertible into or exchangeable for Common Stock (whether or not at
     the time so convertible or exchangeable) or (iii) options, warrants or
     rights to purchase such convertible or exchangeable securities (whether or
     not at the time exercisable), other than in each case Excluded Stock:


               (1) the aggregate maximum number of shares of Common Stock
          deliverable upon exercise of such options, warrants or other rights to
          purchase or acquire Common Stock shall be deemed to have been issued
          at the time such options, warrants or rights were issued and for a
          consideration equal to the consideration (determined in the manner
          provided in subclauses (A) and (B) above), if any, received by the
          Company upon the issuance of such options, warrants or rights plus the
          minimum purchase price provided in such options, warrants or rights
          for the Common Stock covered thereby;

               (2) the aggregate maximum number of shares of Common Stock
          deliverable upon conversion of or in exchange for any such convertible
          or exchangeable securities, or upon the exercise of options, warrants
          or other rights to purchase or acquire such convertible or
          exchangeable securities and the subsequent conversion or exchange
          thereof, shall be deemed to have been issued at the time such
          securities were issued or such options, warrants, or rights were
          issued and for a consideration equal to the consideration, if any,
          received by the Company for any such securities and related options,
          warrants or rights (excluding any cash received on account of accrued
          interest or accrued dividends), plus the additional consideration
          (determined in the manner provided in subclauses (A) and (B) above),
          if any, to be received by the Company upon the conversion or exchange
          of such securities, or upon the exercise of any related options,
          warrants or rights to purchase or acquire such convertible or
          exchangeable securities and the subsequent conversion or exchange
          thereof;

               (3) on any change in the number of shares of Common Stock
          deliverable upon exercise of any such options, warrants or rights or
          conversion or exchange of such convertible or exchangeable securities
          or any change in the consideration to be received by the Company upon
          such exercise, conversion or exchange, including, but not limited to,
          a change resulting from the anti-dilution provisions thereof, the
          Exercise Price as then in effect shall forthwith be readjusted to such
          Exercise Price as would have been obtained had an adjustment been made
          upon 

                                     -125-
<PAGE>
 
          the issuance of such options, warrants or rights not exercised prior
          to such change, or of such convertible or exchangeable securities not
          converted or exchanged prior to such change, upon the basis of such
          change;

               (4) on the expiration or cancellation of any such options,
          warrants or rights or the termination of the right to convert or
          exchange such convertible or exchangeable securities, if the Exercise
          Price shall have been adjusted upon the issuance thereof, the Exercise
          Price shall forthwith be readjusted to such Exercise Price as would
          have been obtained had an adjustment been made upon the issuance of
          such options, warrants, rights or such convertible or exchangeable
          securities on the basis of the issuance of only the number of shares
          of Common Stock actually issued upon the exercise of such options,
          warrants or rights, or upon the conversion or exchange of such
          convertible or exchangeable securities; and

               (5) if the Exercise Price shall have been adjusted upon the
          issuance of any such options, warrants, rights or convertible or
          exchangeable securities, no further adjustment of the Exercise Price
          shall be made for the actual issuance of Common Stock upon the
          exercise, conversion or exchange thereof.

          (D) Excluded Stock.  "Excluded Stock" shall mean (1) shares of Common
              --------------                                                   
     Stock issued by the Company as a stock dividend payable in shares of Common
     Stock, or upon any subdivision or split-up of the outstanding shares of
     Common Stock for which an adjustment to the Exercise Price is made pursuant
     to Section 5(c), (2) options to acquire Common Stock and shares of Common
     Stock issued or to be issued from time to time to directors, officers,
     employees, consultants, advisors, independent contractors and agents of the
     Company pursuant to stock option plans or other employee benefit plans
     approved of by the Board of Directors, or an authorized committee thereof,
     of the Company, (3) the shares of Common Stock issued or issuable upon
     conversion of the Redeemable Series A Convertible Preferred Stock of the
     Company outstanding on December 31, 1995, (4) the shares of Common Stock
     issued or issuable upon exercise of the Warrants and (5) shares of Common
     Stock issued by the Company pursuant to an underwritten public offering of
     Common Stock or pursuant to a public tender or exchange offer.

     (c) Stock Dividends, Subdivisions, Reclassifications or Combinations.  If
         ----------------------------------------------------------------     
the Company shall (i) declare a dividend or make a distribution on its Common
Stock in shares of its Common Stock, (ii) subdivide or reclassify the
outstanding shares of Common Stock into a greater number of shares, or (iii)
combine or reclassify the outstanding Common Stock into a smaller number of
shares, the Exercise Price in effect at the time of the record date for such
dividend or distribution or the effective date of such subdivision, combination
or reclassification shall be proportionately adjusted so that the Holder of this
Warrant who exercises this Warrant after such date shall be entitled to receive
the number of shares of 

                                     -126-
<PAGE>
 
Common Stock which he would have owned or been entitled to receive had this
Warrant been exercised immediately prior to such date. Successive adjustments in
the Exercise Price shall be made whenever any event specified above shall occur.

     (d) Other Distributions.  In case the Company shall fix a record date for
         -------------------                                                  
the making of a distribution to all holders of shares of its Common Stock (i) of
shares of any class other than its Common Stock or (ii) of evidences of
indebtedness of the Company or any subsidiary or (iii) of other assets,
including cash, (excluding dividends or distributions referred to in Section
5(c) above and excluding any cash dividend or cash distribution if the per share
amount when combined with the per share amount of all cash dividends and
distributions paid by the Company on Common Stock during the 365-day period
ending on such record date (as adjusted to appropriately reflect any of the
events referred to in Section 5(c) or in this Section 5(d) and excluding cash
dividends or distributions for which an adjustment to the Exercise Price was
previously made pursuant to this Section 5(d)), does not exceed 10% of the
Current Market Price on such record date) or (iv) of rights or warrants
(excluding those referred to in Section 5(b) above), in each case the Exercise
Price in effect immediately prior thereto shall be reduced immediately
thereafter to the price determined by dividing (1) an amount equal to the
difference resulting from (x) the number of shares of Common Stock outstanding
on such record date multiplied by the Current Market Price on such record date,
less (y) the fair market value (as determined in good faith by the Board of
Directors) of said shares or evidences of indebtedness or assets or rights or
warrants to be so distributed, by (2) the number of shares of Common Stock
outstanding on such record date.  Such adjustment shall be made successively
whenever such a record date is fixed.  In the event that such distribution is
not so made, the Exercise Price then in effect shall be readjusted, effective as
of the date when the Board of Directors determines not to distribute such
shares, evidence of indebtedness, assets, rights or warrants, as the case may
be, to the Exercise Price which would then be in effect if such record date had
not been fixed.

     (e) Other Dilutive Events.  In case any event shall occur as to which the
         ---------------------                                                
provisions of this Section 5 are not strictly applicable but the failure to make
any adjustment relating thereto would not fairly protect the purchase rights
represented by this Warrant in accordance with the essential intent and
principles of this Section 5, then, in each such case, the Company shall
immediately make all adjustments necessary to preserve, without dilution, the
purchase rights represented by this Warrant on a basis consistent with the
intent and principles established in this Section 5 and shall also immediately
appoint a firm of independent certified public accountants of recognized
national standing (which may be the regular auditors of the Company if they
satisfy such standard), which shall give their opinion that such adjustment, if
any, preserves, without dilution, the purchase rights represented by this
Warrant on a basis consistent with the intent and principles established in this
Section 5.  Upon receipt of such opinion, the Company will immediately deliver a
copy thereof to the Holder of this Warrant.  The Company shall not, by amendment
of its certificate of incorporation or through any consolidation, merger,
reorganization, transfer of assets, dissolution, issue or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, and will at all times in good faith assist
in carrying out all of such terms and in the taking of all such actions as may
be necessary or appropriate in order to protect the rights of the Holder of this
Warrant against dilution or other impairment. Without limiting the generality of
the foregoing, the Company (i) will not permit the par value of any shares of
stock receivable upon the exercise 

                                     -127-
<PAGE>
 
of this Warrant to exceed the amount payable therefor upon such exercise, (ii)
will take all such action as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable shares of
stock on the exercise of the Warrants from time to time outstanding, and (iii)
will not take any action which results in any adjustment of the Exercise Price
if the total number of shares of Common Stock issuable after such action upon
the exercise of all of the Warrants would exceed the total number of shares of
Common Stock then authorized by the Company's certificate of incorporation and
available for the purpose of issuance upon such exercise.

     (f) Size of Adjustment; Rounding.  No adjustment in the Exercise Price
         ----------------------------                                      
shall be required unless such adjustment would require an increase or decrease
of at least one cent ($.01) in such price; provided, however, that any
                                           --------                   
adjustment which is thereby not required to be made shall be carried forward and
taken into account in any subsequent adjustment.  All calculations under this
Section 5 shall be made to the nearest cent or to the nearest one-hundredth of a
Share, as the case may be.

     (g) Notice.  Whenever there shall be an adjustment as provided in this
         ------                                                            
Section 5, the Company shall promptly cause written notice thereof to be sent to
the Holder, which notice shall be accompanied by an officer's certificate
setting forth the Exercise Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment and the computation thereof.
However, the failure by the Company to satisfy its obligations under this
Section 5(g) shall not in any manner affect or alter the rights of the Holder
under this Warrant.

     (h) Fractional Shares.  The Company shall not be required to issue
         -----------------                                             
fractions of shares of Common Stock or other capital stock of the Company upon
the exercise of Warrants.  If any fraction of a share would be issuable upon the
exercise of any Warrant (or specified portions thereof), the Company shall
purchase such fraction for an amount in cash equal to the same fraction of the
Current Market Price of such share of Common Stock on the date of exercise of
the Warrant.

     (i) Current Market Price.  The Current Market Price at any date shall mean,
         --------------------                                                   
in the event the Common Stock is publicly traded, the average of the daily
closing prices per share of Common Stock for 30 consecutive trading days ending
3 trading days before such date (as adjusted for any stock dividend, other
dividend for which an adjustment to the Exercise Price would be required
pursuant to Section 5(d), split, combination or reclassification that took
effect during such 30 trading day period).  The closing price for each day shall
be the last reported sale price regular way or, in case no such reported sale
takes place on such day, the average of the last closing bid and asked prices
regular way, in either case on the principal national securities exchange on
which the Common Stock is listed or admitted to trading, or if not listed or
admitted to trading on any national securities exchange, the closing sale price
for such day reported by NASDAQ, if the Common Stock is traded over-the-counter
and quoted in the National Market System, or if the Common Stock is so traded,
but not so quoted, the average of the closing reported bid and asked prices of
the Common Stock as reported by NASDAQ or any comparable system or, if the
Common Stock is not listed on NASDAQ or any comparable system, the average of
the closing bid and asked prices as furnished by two members of the National
Association of Securities Dealers, Inc. selected from time to time by the
Company for that purpose.  If the 

                                     -128-
<PAGE>
 
Common Stock is not traded in such manner that the quotations referred to above
are available for the period required hereunder, the Current Market Price per
share of Common Stock shall be deemed to be the fair value per share of Common
Stock as determined by the Board of Directors of the Company in good faith and
irrespective of any accounting treatment.

     (j) Treasury Stock.  For the purposes of this Section 5, the sale or other
         --------------                                                        
disposition of any Common Stock theretofore held in the Company's treasury shall
be deemed to be an issue thereof.

     (k) Valid Issuance.  All shares of Common Stock which may be issued upon
         --------------                                                      
the exercise of this Warrant will upon issuance by the Company be duly and
validly issued, fully paid and nonassessable and free from all taxes, liens and
charges with respect to the issuance thereof, and the Company shall take no
action which will cause a contrary result (including, without limitation, any
action which would cause the Exercise Price to be less than the par value, if
any, of the Common Stock).

     6.   Certain Corporate Events or Actions.
          ----------------------------------- 

     (a) Consolidation, Merger, Etc.  In case of any consolidation with or
         ---------------------------                                      
merger of the Company with or into another corporation or other entity (except
for a merger or consolidation in which the Company is the continuing corporation
other than as a subsidiary of another corporation or other entity), or in case
of any sale, lease or conveyance to another corporation or other entity of the
assets of the Company as an entirety or substantially as an entirety, such
successor, purchasing, leasing or receiving corporation or other entity, as the
case may be, shall, prior to and as a condition to the occurrence of such event,
(i) execute with the Holder an agreement providing that the Holder shall have
the right thereafter to receive upon exercise of this Warrant the kind and
amount of shares of stock and other securities, property, cash or any
combination thereof receivable upon such consolidation, merger, sale, lease or
conveyance by a holder of the number of shares of Common Stock for which this
Warrant might have been exercised immediately prior to such consolidation,
merger, sale, lease or conveyance (provided that, if the holders of shares have
the right to make an election with respect to the kind or amount of securities,
cash or other property receivable upon consummation of such event, then the kind
and amount of securities, cash or other consideration receivable to the Holder
upon  consummation of such event shall be deemed to be the kind and amount so
receivable per share by a plurality of the shares held by holders of such shares
making such an election) and (ii) make effective provision in its certificate of
incorporation or otherwise, if needed, in order to effect such agreement.  Such
agreement shall provide for adjustments which shall be equivalent to the
adjustments in Section 5 and shall contain provisions equivalent to this Section
6.

     (b) Reclassification, Etc.  In case of any reclassification or change of
         ----------------------                                              
the shares of Common Stock issuable upon exercise of this Warrant or in case of
any consolidation or merger of another corporation or other entity with or into
the Company in which the Company is the continuing corporation (other than as a
subsidiary of another corporation or other entity) and in which there is a
reclassification or change (including a change to the right to receive cash or
other property) of the shares of Common Stock, the Holder shall have the right
thereafter to receive upon exercise of this Warrant the kind and amount of

                                     -129-
<PAGE>
 
shares of stock and other securities, property, cash or any combination thereof
receivable upon such reclassification, change, consolidation or merger by a
holder of the number of shares of Common Stock into which this Warrant would
have been exercisable immediately prior to such reclassification, change,
consolidation or merger (provided that, if the holders of shares have the right
to make an election with respect to the kind or amount of securities, cash or
other property receivable upon consummation of such event, then the kind and
amount of securities, cash or other consideration receivable to the Holder upon
consummation of such event shall be deemed to be the kind and amount so
receivable per share by a plurality of the shares held by holders of such shares
making such an election).  Thereafter, appropriate provision (as determined by
the Board of Directors of the Company in good faith) shall be made for
adjustments which shall be equivalent to the adjustments in Section 5.  This
Section 6(b) shall be applicable to successive reclassifications, changes,
consolidations or mergers.

     7.   Certain Notices.  In case at any time the Company shall propose or
          ---------------                                                   
have knowledge of any proposal:

     (a) to pay any dividend or make any distribution on shares of Common Stock
or to fix a record date for the making of any such dividend or distribution to
holders of Common Stock; or

     (b) to take, or fix a record date for, any action that would result in any
adjustment to the Exercise Price pursuant to Section 5; or

     (c) to effect any reclassification or change of outstanding shares of
Common Stock, or consolidation or merger, or sale, lease or conveyance of
property, of the type addressed in Section 6; or

     (d) to effect any voluntary or involuntary liquidation, dissolution or
winding-up of the Company;

then, and in any one or more of such cases, the Company shall give written
notice thereof to the Holder at least 30 days prior to the date on which (i) the
books of the Company shall close, or a record date shall be set, for any such
action described in Section 7(a) or (b) or (ii) such reclassification, change,
consolidation, merger, sale, lease, conveyance, liquidation, dissolution or
winding-up shall be effective, as the case may be.

     8.   Expenses.  The Company shall pay all costs, fees, taxes (other than
          --------                                                           
any federal or state income or stock transfer taxes) and expenses payable in
connection with the preparation, issuance and delivery from time to time of
Warrants and of shares of Common Stock or other securities issued upon the
exercise of Warrants.

     9.   Restrictions on Transfer.  The Holder, by its acceptance hereof,
          ------------------------                                        
represents and warrants that it is acquiring the Warrants and any Common Stock
issued upon the exercise of this Warrant for investment purposes, for its own
account, and not with an intent to sell or distribute the Warrants or any such
Common Stock except in compliance with applicable United States federal and
state securities law.  Neither this Warrant nor any of the Common Stock issued
upon the exercise of this Warrant, nor any interest in either, may be sold,

                                     -130-
<PAGE>
 
assigned, pledged, hypothecated, encumbered or in any other manner transferred
or disposed of, in whole or in part, except in compliance with applicable United
States federal and state securities laws and the terms and conditions hereof.
The provisions of this Section 9 shall be binding upon all subsequent holders of
this Warrant, if any.  This Warrant and the shares of Common Stock or other
securities issued upon exercise of this Warrant shall be subject to a stop-
transfer order (except with respect to a transfer by SCF III, L.P. of this
Warrant or such shares to its partners who are "accredited investors" within the
meaning of Rule 501 of the Rules and Regulations under the Securities Act of
1933, as amended, (the "Securities Act")) and the certificate or certificates
evidencing any such shares or securities shall bear the following legend:

     "THE SHARES (OR OTHER SECURITIES) REPRESENTED BY THIS CERTIFICATE HAVE BEEN
     ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
     ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER
     JURISDICTION.  SUCH SECURITIES MAY NOT BE SOLD, ASSIGNED OR OTHERWISE
     TRANSFERRED EXCEPT UPON SUCH REGISTRATION OR UPON DELIVERY TO THE
     CORPORATION OF AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
     CORPORATION STATING THAT SUCH SALE, ASSIGNMENT OR TRANSFER IS EXEMPT FROM
     REGISTRATION UNDER SUCH ACT AND LAWS."

     10.  Registration of Common Stock; Listing.  If any shares of Common Stock
          -------------------------------------                                
required to be reserved for purposes of exercise of this Warrant require
registration with or approval of any governmental authority under any federal or
state law before such shares may be issued upon exercise, the Company will, at
its expense and as expeditiously as possible, cause such shares to be duly
registered or approved, as the case may be.  At any such time as Common Stock is
listed for trading, the Company will, at its expense, obtain promptly and
maintain the approval of all securities exchanges (including, for this purpose,
NASDAQ) on which the Common Stock is listed for trading for an additional
listing, upon official notice of issuance, of the shares of Common Stock
issuable upon exercise of the then outstanding Warrants and maintain the listing
of such shares after their issuance.

     11.  Availability of Information.  The Company will comply with the
          ---------------------------                                   
reporting requirements of Sections 13 and 15(d) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act") (or, if the Company is not required to
so comply pursuant to the Exchange Act, it will make publicly available the
information specified by Rule 144(c)(2) under the Securities Act) and will
comply with all other public information reporting requirements of the
Securities and Exchange Commission (the "Commission") (including Rule 144
promulgated by the Commission under the Securities Act) from time to time in
effect and relating to the availability of an exemption from the Securities Act
for the sale of any restricted securities (as defined in the Securities Act) or
the sale of securities by affiliates (as defined in the Securities Act).  The
Company will also cooperate with each holder of any restricted securities in
supplying such information as may be necessary for such holder to complete and
file any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of an exemption from the
Securities Act for the sale of any restricted securities or the sale of
securities by affiliates.  The Company will 

                                     -131-
<PAGE>
 
furnish to each Holder of a Warrant, promptly upon their becoming available,
copies of all financial statements, reports, notices and proxy statements sent
or made available generally by the Company to its stockholders, and copies of
all regular and periodic reports and all registration statements and
prospectuses filed by the Company with any securities exchange or with the
Commission.

     12.  Loss, Theft, Etc.  Upon receipt of evidence satisfactory to the
          -----------------                                              
Company of the loss, theft, destruction or mutilation of any Warrant and upon
surrender and cancellation of any Warrant if mutilated, the Company shall
execute and deliver to the Holder thereof a new Warrant in the form and
substance of the lost, stolen, destroyed or mutilated Warrant (including all
changes and adjustments that have occurred hereunder).  In the event a bond for
security therefor is required, the cost of such bond shall be paid by the
Holder.

     13.  No Rights or Liabilities as a Stockholder.  Nothing contained in this
          -----------------------------------------                            
Warrant shall be construed as conferring upon the Holder hereof any rights as a
stockholder of the Company or as imposing any obligation upon such Holder to
purchase any securities or as imposing any liability upon such Holder as a
stockholder of the Company, whether such obligation or liability is asserted by
the Company or by creditors of the Company at law or in equity.

     14.  Governing Law.  This Warrant shall be governed by and construed in
          -------------                                                     
accordance with the internal laws of the State of Delaware.

     15.  Remedies.  The Company stipulates that the remedies at law of the
          --------                                                         
Holder of this Warrant in the event of any default or threatened default by the
Company in the performance of or compliance with any of the terms of this
Warrant are not and will not be adequate, and that, to the extent permitted by
applicable law, such terms may be specifically enforced by a decree for the
specific performance of any agreement contained herein or by an injunction
against a violation of any of the terms hereof or otherwise.

     16.  Notices.  All notices and other communications provided for herein
          -------                                                           
shall be delivered or mailed by registered or certified mail, return receipt
requested, postage prepaid, addressed (a) if to any Holder of any Warrant, to
the address of such Holder as set forth in the Warrant Register or to such other
address as such Holder has notified the Company of in writing or (b) if to the
Company, to the address set forth in Section 1 or to such other address as the
Company has notified such Holder of pursuant to Section 1 and this Section 16;
provided, however, that the exercise of any Warrant shall be effective in the
manner provided in Section 1.  All notices given pursuant to this Warrant shall
be deemed to be effective upon receipt thereof by the party to whom such notice
is addressed.

     17.  Miscellaneous.  This Warrant and any term hereof may be changed,
          -------------                                                   
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination

  TUBOSCOPE VETCO INTERNATIONAL CORPORATION AND DREXEL OILFIELD SERVICES, LTD.
                        SIGN DEFINITIVE MERGER AGREEMENT

Houston, Texas, January 4, 1996 - Tuboscope Vetco International ("Tuboscope")
(NASDAQ: TUBO), announced today that it has executed a definitive merger
agreement with privately held Drexel Oilfield Services ("DOS").  Through its
Hydra Rig, SWECO-Oilfield Services ("SWECO"), Brandt and Texas Oil Tools
subsidiaries, DOS is the world's leading manufacturer of coiled tubing units,
related pressure control equipment and solids control equipment.  For the twelve
months ended 9/30/95 and pro forma for the recent acquisition of SWECO, DOS had
revenues and EBITDA of approximately $119 million and $16 million respectively,
excluding SWECO combination savings expected to be in excess of $2 million.

The definitive merger agreement provides for the acquisition of DOS for 16.7
million Tuboscope shares.  The largest shareholders of DOS are SCF Partners, a
Houston-based energy services investment group led by Mr. L.E. Simmons, and the
Hong Kong-based Kadoorie Group.  In a related transaction, SCF Partners will
also invest $31 million of new equity in Tuboscope through the purchase of 4.2
million shares of Tuboscope common stock and warrants to purchase 2.533 million
common shares at an exercise price of $10.00 per share.

In a separate agreement, subject to final documentation, Baker Hughes
Incorporated has agreed to exchange Tuboscope's Series A Convertible Preferred
stock for 1.5 million shares 

                                     -150-
<PAGE>
 
of Tuboscope common stock and warrants to purchase an additional 1.25 million
shares at an exercise price of $10.00 per share. As a result of the exchange,
excluding the warrants, Baker Hughes will own approximately 8% of the combined
entity. Eric Mattson, Chief Financial Officer of Baker Hughes, will continue as
a director of Tuboscope. Mr. Mattson stated, "this decision reflects Baker
Hughes' support of the DOS transaction and its confidence in the future of
Tuboscope."

Following the completion of the transactions, SCF Partners will own
approximately 23% of the combined company.  Mr. L.E. Simmons, chairman of DOS
and president of SCF Partners, will become chairman of Tuboscope.  Mr. Martin A.
Reid, current Chairman, will continue as a director.  Mr. John Lauletta,
President and Chief Executive Officer of DOS, will become President and Chief
Executive Officer of Tuboscope.

Completion is subject to certain conditions, including receipt of stockholder
and various government approvals.  The transaction is expected to close in the
second quarter of 1996.

Regarding the transaction, Mr. Reid stated: "The merger with DOS and the $31
million equity investment by SCF Partners will generate many benefits for
Tuboscope shareholders.  Among these benefits are greatly expanded growth
opportunities, particularly in the technically important and growing coiled
tubing and solids control markets; a strengthened balance sheet with which to
pursue future complementary acquisition opportunities; $4-5 million of estimated
consolidation benefits and an anticipated accretion of earnings per share; the
active involvement of Mr. L.E. Simmons whose knowledge, experience and proven
record of building shareholder value in the energy service industry is widely
recognized; and 

                                     -151-
<PAGE>
 
the appointment of Mr. John Lauletta to the position of Chief Executive Officer.
Mr. Lauletta has a broad range of energy service industry experience with
Schlumberger and Baker Hughes, where he was president of Baker Hughes
Exlog/TOTCO and Milpark Drilling Fluids units."

Mr. Reid also noted:  "The effect of the transaction will be to better position
Tuboscope for growth.  The combined company should have excellent earnings
growth and cost reduction opportunities, especially when compared to other mid-
sized energy service companies.  It is unique that a company of its size will
have the worldwide leadership position in virtually all of its business segments
and significant growth opportunities."

L.E. Simmons added: "The worldwide distribution network of the combined entity
offers an excellent platform for the continued growth of DOS' businesses.  A
significant factor for both companies is the high fixed cost of serving
important but geographically dispersed markets.  The combination will facilitate
the serving of these markets with far greater efficiency."  Mr. Simmons also
noted that there are additional synergies in the areas of coiled tubing
inspection and capital equipment technology as well as a substantial customer
overlap in many markets.

Drexel, through its Hydra Rig, SWECO, Brandt and Texas Oil Tools subsidiaries,
is the world's leading provider of solids control services and equipment
including screen separators, centrifuges, environmentally effective closed loop
systems, and coiled tubing related products including coiled tubing units,
nitrogen pumps and vaporizers, snubbing units, stimulation equipment, related
blowout preventers and stripper packers.

                                (ANALYSTS ONLY)
                 Business Overview of Drexel Oilfield Services


General
          Drexel Oilfield Services ("Drexel") is a closely held international
energy service company which manufactures, distributes, and services a wide
variety of capital equipment used in the drilling and production of oil and gas
wells.  Drexel is a leader in most of the specialized equipment markets in which
it participates, including coiled tubing equipment, solids control equipment,
cryogenic vessels, specialized workover tools, and fluid handling equipment.
Its principal manufacturing bases are in Fort Worth (TX), Conroe (TX), and
Montrose (Scotland).  Drexel sells its products through an integrated
distribution network with access to the U.S., North Sea, South America, Far East
and Africa.

          The Company was formed in the mid-1970's through the merger of The
Drexel Company, a North Sea-focused energy service company, and Oilfield
Services Pte, an Asian energy service company.  In the period from January 1988
through September 1990, Drexel acquired Texas Oil Tools, The Brandt Company, and
Hydra Rig, all leading U.S. manufacturing businesses in their respective niches.

          In 1993, the Company underwent a significant restructuring and hired a
new management team, including a new Chief Executive Officer and a Chief
Financial Officer.  John Lauletta, the new President and Chief Executive
Officer, has subsequently implemented tighter financial controls and
rationalized several of the unprofitable operations.

Segment Descriptions

Coiled Tubing/Pressure Control
- ------------------------------

          Drexel's Hydra Rig unit is the world's leading manufacturer of coiled
tubing units, cryogenic transportation and pumping equipment, and other capital
goods used in coiled tubing and workover-related services.  Drexel's management
estimates it holds a 50% market share in the Coiled Tubing/Nitrogen Pumping
market.

          Texas Oil Tools, another Drexel subsidiary, is the leading
manufacturer of specially designed blowout preventers ("BOP's") and associated
pressure control equipment used in coiled tubing and wireline operations.
Drexel estimates it holds a greater than 70% market share in the pressure
control equipment market.

Solids Control
- --------------

          Drexel, through its Brandt subsidiary, is the world's leading
manufacturer, distributor and renter of high technology solids control equipment
including shale shakers, centrifuges, mud cleaners, desanders and desilters used
in drilling operations.  Drexel also recently completed the acquisition of
SWECO, a major competitor in the solids control equipment business.  Together,
management estimates the two companies hold the number one market share in the
solids control equipment market with 40%.

Marketing/Customers

          Drexel's customer base includes major service companies, such as
Dowell, Schlumberger, Halliburton and Baker Hughes as well as national oil
companies, western oil companies and drilling contractors.  The Company's
primary geographical base consists of

the Gulf of Mexico, South America, the North Sea, West Africa and the Far East.
The Company also serves C.I.S., Europe and the Middle East.

Business Strategy/Recent Acquisitions

          During the past twelve months, Drexel has devoted significant effort
to pursuing strategic growth and completed the acquisition of SWECO on November
16, 1995.  The acquisition of SWECO more than doubled the Company's solids
control revenues, especially in South America and increased total revenues by 50
percent.  The Company is also pursuing several other growth transactions in both
its solids control sgand coiled tubing business lines.
