                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and financial data appearing elsewhere in this Prospectus and in
the consolidated financial statements, including the notes thereto, and other
documents which are incorporated herein by reference. As used herein, the terms
"Varco" and the "Company" refer to Varco International, Inc. or Varco and its
subsidiaries, as the context may require.
 
                                  THE COMPANY
 
  Varco International, Inc. is a leading manufacturer of products used in the
oil and gas well drilling industry worldwide. The Company has the leading
market position in most of its product lines and is widely recognized for the
development of new technology and equipment which enhances the productivity and
safety of the drilling process.
 
  The Company's products are sold for use in approximately 82 countries, and
international revenues accounted for approximately 69% of total revenues for
the fiscal year ended December 31, 1995.
 
  Since 1987, Varco has made several strategic acquisitions, which have
significantly increased its revenue base and expanded its product development
opportunities.
 
  Varco operates through five divisions:
 
  Varco Drilling Systems designs and manufactures integrated systems for
rotating and handling the various sizes and types of pipe used on a drilling
rig. It is widely recognized for developing innovative drilling technology and
products. Its principal products are Top Drive Drilling Systems and pipe
handling systems. The Top Drive Drilling System, first introduced in 1982, has
gained acceptance as a safer and more productive technology than conventional
methods for a wide variety of drilling applications. Through mechanization and
automation, Varco's pipe handling systems eliminate the manual handling of pipe
on a drilling rig.
 
  Varco BJ Oil Tools manufactures a complete line of conventional drilling rig
tools and equipment, including pipe handling tools, hoisting equipment and
rotary equipment. Varco BJ is the market leader in virtually all of its product
lines.
 
  Martin-Decker/TOTCO Instrumentation primarily designs, manufactures, sells
and rents products involving the measurement, analysis, recording and display
of information that enhances the productivity and safety of the drilling
process. Its most significant product is the TOTAL System, a computer-based
drilling information system. Based on revenues, Martin-Decker/TOTCO is the
worldwide leader in drilling rig instrumentation.
 
  Shaffer primarily designs and manufactures pressure control equipment,
principally blowout preventers ("BOPs"), for use on drilling rigs. Shaffer also
provides motion compensation equipment for use on floating offshore rigs.
 
  Thule Rigtech designs and sells solids control equipment, which is used on a
drilling rig in the mixing, handling, transport and cleaning of drilling fluids
("drilling mud"). Thule Rigtech is Varco's most recent acquisition, having been
acquired in November 1994.
 
  The principal executive offices of the Company are located at 743 North
Eckhoff Street, Orange, California 92668 (telephone: (714) 978-1900).

                              RECENT DEVELOPMENTS
 
  In recent months offshore drilling activity has increased, raising the
capacity utilization of the worldwide mobile offshore rig fleet to 87% in the
first quarter of 1996, from 81% in the comparable period a year ago. In
particular, the demand for "high specification" rigs (i.e., those capable of
drilling in deeper water and/or harsh environments) has been very strong. The
recent levels of offshore rig utilization represent the highest level in more
than ten years.
 
  These trends benefit Varco in two important ways. First, equipment of the
type supplied by Varco is critical to the upgrading of rigs to meet the
capacity and capability requirements associated with more difficult drilling
conditions. Second, Varco's key customers, the offshore drilling contractors,
are recording their best financial results in many years, thus combining the
incentive and the financial resources to invest in the upgrading of drilling
equipment. As a result, Varco's incoming orders have increased. Order bookings
were $76.9 million in the first quarter of 1995, $85.6 million in the fourth
quarter of 1995, and $102.2 million in the first quarter of 1996, in each case
establishing a new all-time high for the Company.
 
                                  THE OFFERING
 
  All of the shares of Common Stock of the Company offered are being sold by
the Selling Shareholders except to the extent that the over-allotment option
granted by the Company to the Underwriters is exercised. To the extent that the
over-allotment option is exercised, the net proceeds realized by the Company
will be used first for the repayment of indebtedness and then for working
capital or other general corporate purposes. See "Use of Proceeds."
 
  If the over-allotment option is exercised in full, the number of shares of
Common Stock outstanding after the offering will be 31,282,869, based on the
number of shares outstanding at April 19, 1996.

                                 RISK FACTORS
 
  Prospective investors should consider carefully the following factors,
together with the other information appearing in this Prospectus or
incorporated herein by reference before purchasing shares of Common Stock
offered hereby.
 
VOLATILE INDUSTRY CONDITIONS
 
  The Company's operations are materially dependent upon the level of
worldwide drilling activity, particularly offshore drilling. Such activity
levels are affected by both short-term and long-term trends in world oil and
natural gas prices. In recent years, oil and natural gas prices and, therefore
the level of drilling activity, have been extremely volatile. Any prolonged
reduction in oil and natural gas prices would, in all likelihood, depress the
level of drilling activity and result in a decline in the demand for the
Company's products. Any sustained reduction in such activity would, in all
likelihood, have a material adverse effect on the Company's revenues and
profitability.
 
MANAGEMENT OF ACCELERATING GROWTH
 
  The Company's orders and revenues have increased substantially in recent
quarters, particularly in its Drilling Systems and Shaffer Divisions.
Following a number of years of dramatic downsizing, the Company's operating
divisions have been, or may be, required to significantly increase their level
of output. Such increases create strains on existing management and
organization structures, systems and procedures, and human resources. There is
no assurance that these strains will not result in a material adverse effect
on the Company's revenues and profitability.
 
SHARES AVAILABLE FOR FUTURE SALE
 
  Certain shareholders of the Company (including Walter B. Reinhold, one of
the Selling Shareholders) are parties to an Agreement (the "Shareholders'
Agreement") imposing certain restrictions on transfers of certain shares of
Common Stock owned by them and certain of their transferees, which expires on
May 22, 1996. For a further description of these restrictions, see "Selling
Shareholders." Of the approximately 3,200,000 shares of Common Stock subject
to the Shareholders' Agreement, 994,547 shares are beneficially owned by Mr.
Reinhold. Based on information available to the Company and the record list of
holders of the Common Stock of the Company as of March 20, 1996, the other
major holders of shares subject to the Shareholders' Agreement and the number
of shares held by them (individually, as trustee, as executor, or as
custodian) which are subject to the transfer restrictions are as follows:
Baldwin Reinhold, Jr. and Mary E. Reinhold, 907,780 shares; Howard P. Lorenz,
600,331 shares; Baldwin Terry Reinhold and Carol Anne Reinhold, 93,264 shares;
Charlotte L. Llanes, 62,252 shares; Darlene M. Reinhold, 58,292 shares; and
John G. Reinhold, 57,685 shares. Upon the expiration of the Shareholders'
Agreement on May 22, 1996, the shares subject thereto will no longer be
subject to the transfer restrictions contained in the Shareholders' Agreement
although to the extent that any holder of shares formerly subject to the
agreement is an affiliate of the Company, sales of shares may be subject to
the volume limitations of Rule 144 ("Rule 144") under the Securities Act of
1933, as amended (the "Securities Act"). Rule 144 permits an affiliate to
sell, within any three-month period, a number of shares not exceeding the
greater of 1% of the then outstanding shares of the Company's Common Stock
(approximately 302,000 shares based on the number of shares outstanding at
March 31, 1996) or the average weekly trading volume during the four weeks
preceding the date of filing of notice of the proposed sale with the
Securities and Exchange Commission pursuant to Rule 144 (approximately
1,450,000 shares for the four weeks ended April 26, 1996). Assuming that
trading in the Common Stock continues at similar levels, the Rule 144 volume
limitations would not limit sales by any such affiliate. However, Walter B.
Reinhold has agreed that for a period of 120 days after the date of this
Prospectus he will not sell or otherwise dispose of any shares of Common Stock
owned by him except for the shares included in the Offering. See
"Underwriting." Future sales of substantial amounts of Common Stock in the
public market could adversely affect prevailing market prices of the Common
Stock.

<PAGE>
 
                                USE OF PROCEEDS
 
  The Company will not receive any of the proceeds from the sale of the Common
Stock offered by the Selling Shareholders. Any net proceeds to the Company
from the exercise of the over-allotment option, in whole or in part, will be
applied first to the principal payment, due June 30, 1996, in the amount of
$10,000,000 on the Company's 8.95% Senior Notes and then to the repayment of
amounts outstanding under the Company's revolving credit facility ($2,000,000
at March 31, 1996). Advances currently outstanding under the revolving credit
facility bear interest at prime plus .50% (8.75% at March 31, 1996) and mature
on October 31, 1998. Any remaining balance of the net proceeds will be used by
the Company for working capital and other general corporate purposes. In the
event that the over-allotment is not exercised or is not exercised in full,
the Company believes that its cash and cash equivalents and revolving credit
facility will be sufficient to meet its capital expenditures, operating cash
needs and the principal payment on the 8.95% Senior Notes in 1996.
 
                          PRICE RANGE OF COMMON STOCK

  All 6,596,041 shares of Common Stock included in the Offering are being sold
by the Selling Shareholders. The Company has granted to the Underwriters an
option to purchase up to 989,406 additional shares solely to cover over-
allotments, if any.
 
  Of the 6,346,041 shares of Common Stock beneficially owned by Baker Hughes
Incorporated ("Baker Hughes") (1) 3,000,000 were issued to Baker Hughes in
September 1988, as part of the consideration for the acquisition by the
Company of Baker Hughes' BJ Machinery Division, pursuant to the provisions of
an Asset Purchase Agreement, dated as of August 10, 1988 (the "BJ Purchase
Agreement"), (2) an additional 1,000,000 shares were issued to Baker Hughes in
December 1990 upon the exercise (for an aggregate exercise price of
$4,000,000) of a Warrant issued to Baker Hughes as an additional part of the
consideration for the BJ Machinery Division acquisition, and (3) the balance
of 2,346,041 shares were issued to Baker Hughes in November 1990, as part of
the consideration for the acquisition by the Company of Baker Hughes' TOTCO
Product Line, pursuant to the provisions of an Amended and Restated Asset
Purchase Agreement, dated as of August 1, 1990 (the "TOTCO Purchase
Agreement").
 
  The shares being sold by Baker Hughes are being included in the Company's
Registration Statement for the Offering pursuant to certain registration
rights agreed to by the Company in connection with the BJ Machinery Division
and the TOTCO Product Line acquisitions. The Company agreed to pay all
expenses of registering shares on behalf of Baker Hughes other than
underwriting discounts and commissions and any fees or disbursements of Baker
Hughes' counsel. The Company and Baker Hughes have agreed to indemnify each
other against certain liabilities under the Securities Act.
 
  Pursuant to the BJ Purchase Agreement, the Company agreed that, during the
period commencing on the closing date of the BJ Machinery acquisition and
terminating on the earlier of (a) the date on which the Company shall have
discharged in full its obligations to make certain royalty payments to Baker
Hughes under the provisions of the BJ Purchase Agreement and (b) September 29,
1996, it would use its best efforts to cause a designee of Baker Hughes to be
elected to the Company's Board of Directors. Pursuant to the foregoing, James
D. Woods, Chairman and Chief Executive Officer of Baker Hughes, was named as
Baker Hughes' designee and has served as a director of the Company during the
period October 1988 through May 1990 and the period December 1990 to the
present.
 
 
                                       9
<PAGE>
 
  Pursuant to the TOTCO Purchase Agreement, Baker Hughes agreed that (subject
to certain exceptions) so long as Baker Hughes or any subsidiary beneficially
owned any of the shares of Common Stock issued in connection with the BJ
Machinery Division acquisition or the TOTCO Product Line acquisition, and in
any event for at least seven years from November 28, 1990, the date of the
closing of the TOTCO Product Line acquisition, neither Baker Hughes nor any
subsidiary would acquire any additional shares of the Common Stock or rights
or options to acquire the Common Stock if such acquisition would result in
Baker Hughes and its affiliates owning more than 21.8% of Varco's outstanding
Common Stock. Baker Hughes also agreed not to participate in any solicitation
of proxies with respect to Varco during such period.
 
  In addition, Baker Hughes agreed that it would not dispose of any shares of
Common Stock constituting more than 5% of the outstanding shares of such stock
in a privately negotiated transaction or series of transactions to any person
or group of related persons without first offering such shares to the Company
at the price and upon the terms upon which such shares were proposed to be
sold. In such event, the Company may elect to purchase either (i) all of such
shares or (ii) any or all of such shares in excess of 3,000,000 shares on the
terms of the proposed sale. Baker Hughes also agreed that it would not dispose
of any shares of Common Stock constituting more than 3% of the outstanding
shares of stock in open market transactions or in any other manner (other than
a privately negotiated transaction) over a period of six months or less
without first offering to the Company such shares as would cause the total
number of shares sold by Baker Hughes during such period to exceed 3% of the
outstanding shares. The Company has waived its rights of first refusal in
connection with the Offering.
 
  Walter B. Reinhold is Chairman of the Board of Directors of the Company. All
of the shares included in the Offering by Mr. Reinhold were acquired by him by
gift or inheritance from his father prior to 1977.
 
  Mr. Reinhold, Baldwin Reinhold, Jr., the estate of Charlotte Reinhold
Lorenz, deceased, and Baldwin T. Reinhold, the son of Baldwin Reinhold, Jr.,
are parties to an Agreement dated as of June 11, 1981 (the "Shareholders'
Agreement") imposing certain restrictions on transfers of shares of Common
Stock owned by them at the time the Shareholders' Agreement became effective
and any additional voting securities of the Company issued with respect
thereto by way of stock dividend, stock split or other distribution.
Specifically, the Shareholders' Agreement prohibits any transfer except (1)
any transfer pursuant to a registration statement under the Securities Act,
(2) the sale by any party of not more than 20,000 shares (adjusted to reflect
any stock dividends, stock splits or reverse stock splits) during any 12-month
period pursuant to Rule 144, (3) inter vivos gifts, provided that the
aggregate value given by any party to any one person during any 12-month
period does not exceed $50,000 ($500,000 in the case of direct or indirect
gifts to a member of the donor's family or the donor's former spouse), (4)
bequests or inter vivos gifts, direct or indirect, to charitable institutions,
provided that the aggregate value given by any party to charitable
institutions during any 12-month period does not exceed $2,000,000, (5)
transfers by will or the laws of descent and distribution, or (6) transfers
with the written consent of the holders of 80% of the shares then subject to
the Shareholders' Agreement. Any transferee under clause (3) or (6) above must
agree to be bound by the provisions of the Shareholders' Agreement restricting
transfers unless, in the case of any transfer under clause (6), otherwise
agreed by the parties approving such transfer, and any transferee under clause
(5) above other than a charitable institution is deemed to be bound by such
provisions. Unless sooner terminated by the parties, the foregoing
restrictions terminate on May 22, 1996. Approximately 3,200,000 shares of
Common Stock, or 10.6% of the shares outstanding at March 31, 1996, are
currently subject to the Shareholders' Agreement.

  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will be
obligated to purchase all of the shares of Common Stock offered hereby (other
than those shares covered by the over-allotment option described below) if any
are purchased. The Underwriting Agreement provides that, in the event of a
default by an Underwriter, in certain circumstances the purchase commitments
of non-defaulting Underwriters may be increased or the Underwriting Agreement
may be terminated.
 
  The Company has granted the Underwriters an option expiring at the close of
business on the 30th day after the date of this Prospectus, exercisable by CS
First Boston, to purchase up to an additional 989,406 shares from the Company

exercised only to cover over-allotments in the sale of shares of the Common
Stock. To the extent that the Underwriters exercise such option, each
Underwriter will become obligated, subject to certain conditions, to purchase
a number of option shares proportionate to such Underwriter's initial
commitment as indicated in the preceding table.
 
  The Company has been advised by the Representatives that the Underwriters
propose to offer the shares to the public initially at the public offering

                         NOTICE TO CANADIAN RESIDENTS
 
RESALE RESTRICTIONS
 
  The distribution of the Common Stock in Canada is being made only on a
private placement basis exempt from the requirement that the Company or the
Selling Shareholders prepare and file a prospectus with the securities
regulatory authorities in each province where trades of Common Stock are
effected. Accordingly, any resale of the Common Stock in Canada must be made
in accordance with applicable securities laws which will vary depending on the
relevant jurisdiction, and which may require resales to be made in accordance
with available statutory exemptions or pursuant to a discretionary exemption
granted by the applicable Canadian securities regulatory authority. Purchasers
are advised to seek legal advice prior to any resale of the Common Stock.
 
REPRESENTATIONS OF PURCHASERS
 
  Each purchaser of Common Stock in Canada who receives a purchase
confirmation will be deemed to represent to the Selling Shareholders and/or
the Company and the dealer from whom such purchase confirmation is received
that (i) such purchaser is entitled under applicable provincial securities
laws to purchase such Common Stock without the benefit of a prospectus
qualified under such securities laws, (ii) where required by law, that such
purchaser is purchasing as principal and not as agent, and (iii) such
purchaser has reviewed the text above under "Resale Restrictions."
 
  The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
section 32 of the Regulation under the Securities Act (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available,
including common law rights of action for damages or rescission or rights of
action under the civil liability provisions of the U.S. federal securities
laws.
 
  All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be
possible for Ontario purchasers to effect service of process within Canada
upon the issuer or such persons. All or a substantial portion of the assets of
the issuer and such persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or such
persons in Canada or to enforce a judgment obtained in Canadian courts against
such issuer or persons outside of Canada.
 
NOTICE TO BRITISH COLUMBIA RESIDENTS
 
  A purchaser of Common Stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
Common Stock acquired by such purchaser pursuant to this Offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR 95/17, a copy of which may be obtained from the Company. Only one
such report must be filed in respect of Common Stock acquired on the same date
and under the same prospectus exemption.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 204(a)(10) of the California General Corporation Law (the "GCL")
permits a corporation, in its Articles of Incorporation, to eliminate or limit
the personal liability of directors for monetary damages in an action brought
by or in the right of the corporation (a "derivative action") for breach of a
director's duties to the corporation provided, however, that such a provision
may not eliminate or limit the liability of directors for: (1) acts or
omissions that involve intentional misconduct or a knowing and culpable
violation of law; (2) acts or omissions that a director believes to be
contrary to the best interests of the corporation or its shareholders or that
involve the absence of good faith on the part of the director; (3) any
transaction from which the director derived an improper personal benefit; (4)
acts or omissions that show a reckless disregard for the director's duty to
the corporation or its shareholders in circumstances in which the director was
aware, or should have been aware, in the ordinary course of performing a
director's duties, of a risk of serious injury to the corporation or its
shareholders; (5) acts or omissions that constitute an unexcused pattern of
inattention that amounts to an abdication of the director's duty to the
corporation or its shareholders; (6) transactions between a corporation and
its directors or corporations having interrelated directors under Section 310
of the GCL; or (7) improper distributions to shareholders, loans or guaranties
under Section 316 of the GCL.
 
  Section 204(a)(11) of the GCL permits a corporation in its Articles of
Incorporation to provide for indemnification of directors, officers, employees
and other agents by bylaw, agreement or otherwise in excess of that expressly
permitted by Section 317 of the GCL except that provision may not be made for
indemnification which is expressly prohibited by Section 317 of the GCL or for
acts or omissions from which a director may not be relieved of liability under
Section 204(a)(10) of the GCL.
 
  Section 317(b) of the GCL permits a corporation to indemnify a director,
officer, employee or other agent against expenses, judgments, fines,
settlements and other amounts incurred in connection with any proceeding other
than a derivative action if he acted in good faith and in a manner he
reasonably believed to be in the best interests of the corporation and, in the
case of a criminal proceeding, had no reasonable cause to believe that his
conduct was unlawful.
 
  With respect to derivative actions, Section 317(c) of the GCL permits a
corporation to indemnify a director, officer, employee or other agent against
expenses incurred in connection with the defense or settlement of such an
action if he acted in good faith and in a manner which he believed to be in
the best interests of the corporation
 
                                     II-1
<PAGE>
 
and its shareholders. Under Section 317(c), indemnification in a derivative
action is not permitted (1) with respect to any matter in which the person
seeking indemnification is held to be liable to the corporation in the
performance of his duties to the corporation and its shareholders unless and
only to the extent that the court in which the proceeding was brought
determines that, in view of all of the circumstances of the case, such person
is fairly and reasonably entitled to indemnification for expenses and then
only to the extent that such court shall determine; (2) for any amount paid in
settling or otherwise disposing of a pending action without court approval; or
(3) for expenses incurred in defending a pending action which is settled or
otherwise disposed of without court approval.
 
  Section 317(d) of the GCL requires a corporation to indemnify any director,
officer, employee or other agent for all expenses actually and reasonably
incurred by him in any proceeding to the extent that he is successful on the
merits.
 
  The Company's Amended and Restated Articles of Incorporation (1) eliminate
the liability of directors for monetary damages to the fullest extent
permitted under California law and (2) permit the Company to provide
indemnification to directors, officers, employees and other agents by bylaw
provisions, agreements, vote of shareholders or disinterested directors, or
otherwise, in excess of the indemnification otherwise permitted by Section 317
of the GCL, subject only to the limits set forth in Section 204 of the GCL.
 
  The Bylaws of the Company generally require indemnification of any officer
or director of the Company for all costs, charges, expenses, liabilities and
losses (including attorneys' fees, judgments, fines, ERISA excise taxes or
penalties, and amounts paid in settlement) incurred in any action, suit or
proceeding by reason of the fact that he is or was a director of the Company,
except to the extent that such indemnification would be expressly prohibited
under California law or the Company's Amended and Restated Articles of
Incorporation.
 
  The Company is a party to an Indemnity Agreement with each of its directors
and executive officers which generally provides the indemnitee with a
contractual right to indemnification for all Expenses (which is defined to
include attorneys' fees and amounts paid in settlement), judgments, fines,
penalties and ERISA excise taxes incurred in any action, suit or proceeding by
reason of his position with the Company, except to the extent that such
indemnification is prohibited by California law.
 
  The Company also maintains a liability insurance policy under which officers
and directors are generally indemnified against losses and liability
(including costs, expenses, settlements and judgments) incurred by them in
such capacities, other than specified excluded losses.

registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.
 
  (c) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

Howard, Weil, Labouisse,
 Friedrichs Incorporated
Simmons & Company International
 As Representatives of the Several Underwriters,
 c/o CS First Boston Corporation,
     Park Avenue Plaza
     New York, NY 10055

Dear Sirs:

     1.   Introduction.  Baker Hughes Incorporated, a Delaware corporation
("Baker Hughes"), and Walter B. Reinhold, an individual ("Reinhold" and,
together with Baker Hughes, "Selling Stockholders") propose severally to sell an
aggregate of 6,596,041 outstanding shares ("Firm Securities") of the Common
Stock ("Securities"), of Varco International, Inc., a California corporation
("Company"), and the Company proposes to issue and sell to the Underwriters, at
the option of the Underwriters, an aggregate of not more than 989,406 additional
shares ("Optional Securities") of the Company's Securities as set forth below.
The Firm Securities and the Optional Securities are herein collectively called
the "Offered Securities."  The Selling Stockholders and the Company hereby agree
with the several Underwriters named in Schedule A hereto ("Underwriters") as
follows:

     2.   Representations and Warranties of the Company and the Selling
Stockholders.  (a)  The Company represents and warrants to, and agrees with, the
several Underwriters and the several Selling Stockholders that:

          (i)     A registration statement (No. 333-02869) relating to the
     Offered Securities, including a form of prospectus, has been filed with the
     Securities and Exchange Commission ("Commission") and either (A) has been
     declared effective under the Securities Act of 1933, as amended ("Act"),
     and is not proposed to be amended or (B) is proposed to be amended by
     amendment or post-effective amendment. If such registration statement (the
     "initial registration statement") has been declared effective, either (A)
     an additional registration statement (the "additional registration
     statement") relating to the Offered Securities may have been filed with the
     Commission pursuant to Rule 462(b) under the Act ("Rule 462(b)") and, if so
     filed, has become effective upon
<PAGE>
 
     filing pursuant to such Rule and the Offered Securities all have been duly
     registered under the Act pursuant to the initial registration statement
     and, if applicable, the additional registration statement, or (B) such an
     additional registration statement may be proposed to be filed with the
     Commission pursuant to Rule 462(b) and, if so filed, will become effective
     upon filing pursuant to such Rule and upon such filing the Offered
     Securities will all have been duly registered under the Act pursuant to the
     initial registration statement and, if applicable, such additional
     registration statement.  If the Company does not propose to amend the
     initial registration statement or if an additional registration statement
     has been filed and the Company does not propose to amend it, and if any
     post-effective amendment to either such registration statement has been
     filed with the Commission prior to the execution and delivery of this
     Agreement, the most recent amendment (if any) to each such registration
     statement has been declared effective by the Commission or has become
     effective upon filing pursuant to Rule 462(c) under the Act ("Rule 462(c)")
     or, in the case of the additional registration statement, Rule 462(b).  For
     purposes of this Agreement, "Effective Time" with respect to the initial
     registration statement or, if filed prior to the execution and delivery of
     this Agreement, the additional registration statement means (A) if the
     Company has advised the Representatives that it does not propose to amend
     such registration statement, the date and time as of which such
     registration statement, or the most recent post-effective amendment thereto
     (if any) filed prior to the execution and delivery of this Agreement, was
     declared effective by the Commission or has become effective upon filing
     pursuant to Rule 462(c), or (B) if the Company has advised the
     Representatives that it proposes to file an amendment or post-effective
     amendment to such registration statement, the date and time as of which
     such registration statement, as amended by such amendment or post-effective
     amendment, as the case may be, is declared effective by the Commission.  If
     an additional registration statement has not been filed prior to the
     execution and delivery of this Agreement but the Company has advised the
     Representatives that it proposes to file one, "Effective Time" with respect
     to such additional registration statement means the date and time as of
     which such registration statement is filed and becomes effective pursuant
     to Rule 462(b).  "Effective Date" with respect to the initial registration
     statement or the additional registration statement (if any) means the date
     of the Effective Time thereof.  The initial registration statement, as
     amended at its Effective Time, including all information contained in the
     additional registration statement (if any) and deemed to be a part of the
     initial registration statement as of the Effective Time of the additional
     registration statement pursuant to the General Instructions of the Form on
     which it is filed and including all information (if any) deemed to be a
     part of the initial registration statement as of its Effective Time
     pursuant to Rule 430A(b) under the Act ("Rule 430A(b)"), is hereinafter
     referred to as the "Initial Registration Statement."  The additional
     registration statement, as amended at its Effective Time, including the
     contents of the initial registration statement incorporated by reference
     therein and including all information (if any) deemed to be a part of the
     additional registration statement as of its Effective Time pursuant to Rule
     430A(b), is hereinafter referred to as the "Additional Registration
     Statement."  The Initial Registration Statement and the Additional
     Registration Statement are hereinafter referred to collectively as the
     "Registration Statements" and individually as a "Registration Statement."
     The form of prospectus relating to the Offered Securities, as first filed
     with the Commission pursuant to and in accordance with Rule 424(b) or (if

                                       2
<PAGE>
 
     no such filing is required) as included in a Registration Statement, is
     hereinafter referred to as the "Prospectus." No document has been or will
     be prepared or distributed in reliance on Rule 434 under the Act.

          (ii)    If the Effective Time of the Initial Registration Statement is
     prior to the execution and delivery of this Agreement:  (A) on the
     Effective Date of the Initial Registration Statement, the Initial
     Registration Statement conformed in all respects to the requirements of the
     Act and the rule and regulations of the Commission ("Rules and
     Regulations") and did not include any untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     to make the statements therein not misleading; (B) on the Effective Date of
     the Additional Registration Statement (if any), each Registration Statement
     conformed, or will conform, in all respects to the requirements of the Act
     and the Rules and Regulations and did not include, or will not include, any
     untrue statement of a material fact and did not omit, or will not omit, to
     state any material fact required to be stated therein or necessary to make
     the statements therein not misleading; and (C) on the date of this
     Agreement, the Initial Registration Statement and, if the Effective Time of
     the Additional Registration Statement is prior to the execution and
     delivery of this Agreement, the Additional Registration Statement each

     424(b) or (if no such filing is required) at the Effective Date of the
     Additional Registration Statement in which the Prospectus is included, each
     Registration Statement and the Prospectus will conform, in all respects to
     the requirements of the Act and the Rules and Regulations, and neither of
     such documents includes, or will include, any untrue statement of a
     material fact or omits, or will omit, to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading.  If the Effective Time of the Initial Registration Statement is

     conduct its business as described in the Prospectus; and the Company is
     duly qualified to do business as a foreign corporation and is in good
     standing in all other jurisdictions in which its ownership or lease of

     material adverse effect on the

                                       3

     financial condition or business prospects of the Company and its

     as a foreign corporation and is in good standing in all other jurisdictions
     in which its ownership or lease of property or the conduct of its business
     requires such qualification (except for jurisdictions in which the failure
     to so qualify would not have a material adverse effect on the financial
     condition or business prospects of the Company and its subsidiaries, taken
     as a whole); all of the issued and outstanding capital stock of each
     subsidiary of the Company has been duly authorized and validly issued and
     is fully paid and nonassessable; and the capital stock of each subsidiary
     owned by the Company, directly or through subsidiaries, is owned free from

     nonassessable; the Offered Securities conform to the description thereof
     contained in the Prospectus; and the stockholders of the Company have no
     preemptive rights with respect to the Securities.

          (vi)    Except as disclosed in the Prospectus, there are no contracts,

     the sale of the Offered Securities.

          (vii)   No consent, approval, authorization, or order of, or filing

     obtained or made by the Company for the consummation of the transactions
     contemplated by this Agreement in connection with the sale of the Offered
     Securities, except such as have been obtained and made under the Act and
     such as may be required under state securities laws.

          (viii)   The execution, delivery and performance of this Agreement,
     and the consummation of the transactions herein contemplated will not
     result in a breach or violation of any of the terms or provisions of, or
     constitute a default under, any statute, rule, regulation or order of any
     governmental agency or body or any court, domestic or foreign, having
     jurisdiction over the Company or any subsidiary of the Company or any of
     their properties, or any agreement or instrument to which the Company or
     any such subsidiary is a party or by which the Company or any such
     subsidiary is bound or to which any of the properties of the Company or any
     such subsidiary is subject, or the charter or bylaws of the Company or any
     such subsidiary (except as rights to indemnification and contribution may

     except as disclosed in the Prospectus, the Company and its subsidiaries

          (xi)     The Company and its subsidiaries possess adequate
     certificates, authorizations or permits issued by appropriate governmental
     agencies or bodies necessary to conduct the business now operated by them
     and have not received any notice of proceedings relating to the revocation
     or modification of any such certificate, authority or permit that, if
     determined adversely to the Company or any of its subsidiaries, would
     individually or in the aggregate have a material adverse effect on the
     Company and its subsidiaries taken as a whole.

          (xii)    No labor dispute with the employees of the Company or any
     subsidiary exists or, to the knowledge of the Company, is imminent that
     might have a material adverse effect on the Company and its subsidiaries
     taken as a whole.

          (xiii)   The Company and its subsidiaries own, possess or can acquire
     on reasonable terms adequate trademarks, trade names and other rights to
     inventions, know-how, patents, copyrights, confidential information and
     other intellectual property (collectively, "intellectual property rights")
     necessary to conduct the business now operated by them, or presently
     employed by them, and have not received any notice of infringement of or
     conflict with asserted rights of others with respect to any intellectual
     property rights that, if determined adversely to the Company or any of its
     subsidiaries, would individually or in the aggregate have a material
     adverse effect on the Company and its subsidiaries taken as a whole.

          (xiv)    Except as disclosed in the Prospectus, neither the Company
     nor any of its subsidiaries is in violation of any statute, rule,

          (xv)     Except as disclosed in the Prospectus, there are no pending
     actions, suits or proceedings against or affecting the Company, any of its
     subsidiaries or any of their respective properties that, if determined
     adversely to the Company or any of its subsidiaries, would individually or
     in the aggregate have a material adverse effect on the condition (financial
     or other), business, properties or results of operations of the Company and
     its subsidiaries taken as a whole, or would materially and adversely affect
     the ability of the Company to perform its obligations under this Agreement,

     the Company's knowledge, contemplated.

          (xvi)    The financial statements included in each Registration
     Statement and the Prospectus present fairly the financial position of the
     Company and its consolidated subsidiaries as of the dates shown and their

     financial statements have been prepared in conformity with generally
     accepted accounting principles in effect in the United States, applied on a
     consistent basis, except as disclosed therein; the assumptions used in
     preparing the pro forma financial information included in each Registration
     Statement and the Prospectus under the caption "Capitalization" provide a
     reasonable basis for presenting the significant effects directly
     attributable to the transactions or events described therein; the related
     pro forma adjustments give appropriate effect to those assumptions; and the
     pro forma columns therein reflect the proper application of those
     adjustments to the corresponding historical financial statement amounts.

     defined in the Investment Company Act of 1940, as amended.

          (xix)    Neither the Company nor any of its affiliates does business
     with the government of Cuba or with any person or affiliate located in Cuba
     within the meaning of Section 517.075, Florida Statutes and the Company
     agrees to comply with such Section if prior to the completion of the
     distribution of the Offered Securities it commences doing such business.

     (b)  Each Selling Stockholder severally and not jointly represents and
warrants to, and agrees with, the several Underwriters that:

                                       6
<PAGE>
 
          (i)     Such Selling Stockholder has, and on the First Closing Date
     will have, valid and unencumbered title to the Firm Securities to be
     delivered by such Selling Stockholder on such Closing Date and full right,
     power and authority to enter into this Agreement and to sell, assign,
     transfer and deliver the Firm Securities to be delivered by such Selling
     Stockholder on such Closing Date; and upon the delivery of and payment for
     the Firm Securities to be delivered by such Selling Stockholder on such
     Closing Date the several Underwriters will acquire valid and unencumbered
     title to the Firm Securities to be delivered by such Selling Stockholder.

          (ii)    If the Effective Time of the Initial Registration Statement is
     prior to execution and delivery of this Agreement:  (A) on the Effective
     Date of the Initial Registration Statement, the Initial Registration
     Statement conformed in all respects to the requirements of the Act and the
     Rules and Regulations and did not include any untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading; (B) on
     the Effective Date of the Additional Registration Statement (if any), each
     Registration Statement conformed, or will conform, in all respects to the
     requirements of the Act and the Rules and Regulations and did not include,
     or will not include, any untrue statement of a material fact and did not
     omit, or will not omit, to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading; and (C)
     on the date of this Agreement, the Initial Registration Statement and, if
     the Effective Time of the Additional Registration Statement is prior to the
     execution and delivery of this Agreement, the Additional Registration
     Statement, each conforms, and at the time of filing of the Prospectus
     pursuant to Rule 424(b) or (if no such filing is required) at the Effective
     Date of the Additional Registration Statement in which the Prospectus is
     included, each Registration Statement and the Prospectus will conform, in
     all respects to the requirements of the Act and the Rules and Regulations,
     and neither of such documents includes, or will include, any untrue
     statement of a material fact or omits, or will omit, to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading.  If the Effective Time of the Initial Registration
     Statement is subsequent to the execution and delivery of this Agreement:
     on the Effective Date of the Initial Registration Statement, the Initial
     Registration Statement and the Prospectus will conform in all respects to
     the requirements of the Act and the Rules and Regulations; and neither of
     such documents will include any untrue statement of a material fact or will
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading.  The two preceding sentences
     apply only to the extent that any statements in or omissions from a
     Registration Statement or the Prospectus are based on written information
     furnished to the Company by such Selling Stockholder specifically for use
     therein.

     3.   Purchase, Sale and Delivery of Offered Securities.  On the basis of
the representations, warranties and agreements herein contained, but subject to
the terms and conditions herein set forth, each of the Selling Stockholders
agrees, severally and not jointly, to sell to the Underwriters, and the
Underwriters agree, severally and not jointly, to purchase from each Selling
Stockholder, at a purchase price of $______ per share, the respective numbers

                                       7
<PAGE>
 
of Firm Securities set forth below the name of such Selling Stockholder and
opposite the name of such Underwriter set forth in Schedule A hereto.

     Certificates in negotiable form for the Firm Securities to be sold by
Reinhold have been placed in custody, for delivery under this Agreement, under a
Custody Agreement with _____________, as custodian ("Custodian").  Reinhold
agrees that the Firm Securities represented by the certificates held in custody
for him under such Custody Agreement are subject to the interest of the
Underwriters hereunder, that the arrangements made by him for such custody are
to that extent irrevocable, and that his obligations hereunder shall not be
terminated by operation of law, whether due to Reinhold's death or the
occurrence of any other event.  If Reinhold should die, or if any other such
event should occur, before the delivery of the Firm Securities hereunder,
certificates for the Firm Securities shall be delivered by the Custodian to the
Representatives in accordance with the terms and conditions of this Agreement as
if such death or other event had not occurred, regardless of whether or not the
Custodian shall have received notice of such death or other event.

     Baker Hughes and the Custodian will deliver the Firm Securities to be
delivered by them to the Representatives for the accounts of the Underwriters at
the office of Latham & Watkins, 633 West Fifth Street, Suite 4000, Los Angeles,
California, against payment of the purchase price thereof by official bank
checks in Federal Reserve funds drawn to the orders of such Selling Stockholders
at the office of Latham & Watkins, or by wire transfer to the respective
accounts of such Selling Stockholders at banks mutually acceptable to CS First
Boston and each such Selling Stockholder, at 10:00 a.m., New York time, on May
__, 1996, or at such other time not later than three full business days
thereafter as CS First Boston Corporation ("CS First Boston") and Baker Hughes
determine, such time being herein referred to as the "First Closing Date."  For
purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, the First
Closing Date (if later than the otherwise applicable settlement date) shall be
the settlement date for payment of funds and delivery of securities for all the
Firm Securities sold pursuant to the offering.  The certificates for the Firm
Securities so to be delivered will be in definitive form, in such denominations
and registered in such names as CS First Boston requests and will be made
available for checking and packaging at the office of CS First Boston, 55 East
52nd Street, New York, New York, at least 24 hours prior to the First Closing
Date.

     In addition, upon written notice from CS First Boston given to the Company
from time to time not more than 30 days subsequent to the date of the
Prospectus, the Underwriters may purchase all or less than all of the Optional
Securities at the purchase price per Security to be paid for the Firm
Securities.  The Company agrees to sell to the Underwriters the number of shares
of Optional Securities specified in such notice and the Underwriters agree,
severally and not jointly, to purchase such Optional Securities.  Such Optional
Securities shall be purchased for the account of each Underwriter in the same
proportion as the number of Firm Securities set forth opposite such
Underwriter's name bears to the total number of Firm Securities (subject to
adjustment by CS First Boston to eliminate fractions) and may be purchased by
the Underwriters only for the purpose of covering over-allotments made in
connection with the sale of the Firm Securities.  No Optional Securities shall
be sold or delivered unless the Firm Securities previously have been, or
simultaneously are, sold and delivered.  The right to purchase the Optional
Securities or any portion thereof may be exercised from time to time and, to the
extent

                                       8
<PAGE>
 
not previously exercised, may be surrendered and terminated at any time upon
notice by CS First Boston to the Company.

     Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "Optional Closing Date," which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by CS
First Boston but shall be not later than three full business days after written
notice of election to purchase Optional Securities is given.  The Company will
deliver the Optional Securities being purchased on each Optional Closing Date to
the Representatives for the accounts of the several Underwriters, against
payment of the purchase price therefor by official bank check or checks in
Federal Reserve funds drawn to the order of the Company at the above office of
Latham & Watkins, or by wire transfer to the Company's account at a bank
acceptable to CS First Boston.  The certificates for the Optional Securities
being purchased on each Optional Closing Date will be in definitive form, in
such denominations and registered in such names as CS First Boston requests upon
reasonable notice prior to such Optional Closing Date and will be made available
for checking and packaging at the above office of CS First Boston at a
reasonable time in advance of such Optional Closing Date.

     4.   Offering by Underwriters.  It is understood that the several
Underwriters propose to offer the Offered Securities for sale to the public as
set forth in the Prospectus.

     5.   Certain Agreements of the Company and the Selling Stockholders.  The
Company agrees with the several Underwriters and the several Selling
Stockholders that:

     (a)  If the Effective Time of the Initial Registration Statement is prior
to the execution and delivery of this Agreement, the Company will file the
Prospectus with the Commission pursuant to and in accordance with subparagraph
(1) (or, if applicable and if consented to by CS First Boston, subparagraph (4)
of Rule 424(b)) not later than the earlier of (A) the second business day
following the execution and delivery of this Agreement, or (B) the fifteenth
business day after the Effective Date of the Initial Registration Statement. The
Company will advise CS First Boston promptly of any such filing pursuant to Rule
424(b). If the Effective Time of the Initial Registration Statement is prior to
the execution and delivery of this Agreement and an additional registration
statement is necessary to register a portion of the Offered Securities under the
Act but the Effective Time thereof has not occurred as of such execution and
delivery, the Company will file the additional registration statement or, if
filed, will file a post-effective amendment thereto with the Commission pursuant
to and in accordance with Rule 462(b) on or prior to 10:00 p.m., New York time,
on the date of this Agreement or, if earlier, on or prior to the time the
Prospectus is printed and distributed to any Underwriter, or will make such
filing at such later date as shall have been consented to by CS First Boston.

     (b)  The Company will advise CS First Boston promptly of any proposal to
amend or supplement the initial registration statement or any additional
registration statement as filed or the related prospectus or the Initial
Registration Statement, the Additional Registration Statement (if any) or the
Prospectus and will not effect such amendment or supplementation without CS
First Boston's consent; and the Company will also advise CS First Boston
promptly of the effectiveness of each Registration Statement (if its Effective
Time is subsequent to the execution

                                       9
<PAGE>
 
and delivery to this Agreement) and of any amendment or supplementation of a
Registration Statement or the Prospectus and of the institution by the
Commission of any stop order proceedings in respect of a Registration Statement
and will use its best efforts to prevent the issuance of any such stop order and
to obtain as soon as possible its lifting, if issued.

     (c)  If, at any time when a prospectus relating to the Offered Securities
is required to be delivered under the Act in connection with sale by any
Underwriter or dealer, any event occurs as a result of which the Prospectus as
then amended or supplemented would include an untrue statement of a material
fact or omit to state any material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or if it is necessary at any time to amend the Prospectus to comply
with the Act, the Company will promptly notify CS First Boston of such event and
will promptly prepare and file with the Commission, at its own expense, an
amendment or supplement which will correct such statement or omission or will
effect such compliance. Neither CS First Boston's consent to, nor the
Underwriters' delivery of, any such amendment or supplement shall constitute a
waiver of any of the conditions set forth in Section 6.

     (d)  As soon as practicable, but not later than the Availability Date (as
defined below), the Company will make generally available to its securityholders
an earnings statement covering a period of at least 12 months beginning after
the Effective Date of the Initial Registration Statement (or, if later, the
Effective Date of the Additional Registration Statement) which will satisfy the
provisions of Section 11(a) of the Act.  For the purpose of the preceding
sentence, "Availability Date" means the 45th day after the end of the fourth
fiscal quarter following the fiscal quarter that includes such Effective Date,
except that if such fourth fiscal quarter is the last quarter of the Company's
fiscal year, "Availability Date" means the 90th day after the end of such fourth
fiscal quarter.

     (e)  The Company will furnish to the Representatives and to Baker Hughes
copies of each Registration Statement (of which, three copies for the
Representatives and one copy for Baker Hughes will be signed and will include
all exhibits), each related preliminary prospectus, and, so long as delivery of
a prospectus relating to the Offered Securities is required under the Act in
connection with sales by any Underwriter or dealer, the Prospectus and all
amendments and supplements to such documents, in each case in such quantities as
CS First Boston requests.  The Prospectus shall be so furnished on or prior to
3:00 p.m., New York time, on the business day following the later of the
execution and delivery this Agreement or the Effective Time of the Initial
Registration Statement.  All other such documents shall be so furnished as soon
as available.  The Company will pay the expenses of printing and distributing to
the Underwriters all such documents.

     (f)  The Company will arrange for the qualification of the Offered
Securities for sale under the laws of such jurisdictions as CS First Boston
designates and will continue such qualifications in effect so long as required
for the distribution, except that in no event shall the Company be obligated in
connection therewith to qualify as a foreign corporation or to execute a general
consent for the service of process.

                                       10
<PAGE>
 
     (g)  During the period of two years hereafter, the Company will furnish to
the Representatives and, upon request, to each of the other Underwriters, as
soon as practicable after the end of each fiscal year, a copy of its annual
report to stockholders for such year; and the Company will furnish to the
Representatives as soon as available, a copy of each report and any definitive
proxy statement of the Company filed with the Commission under the Securities
Exchange Act of 1934 or mailed to stockholders.

     (h)  For a period of 120 days after the date of the initial public offering
of the Offered Securities, neither the Company nor Reinhold will offer, sell,
contract to sell, pledge or otherwise dispose of, directly or indirectly, or
file with the Commission a registration statement under the Act relating to any
additional shares of its or his Securities or securities convertible into or
exchangeable or exercisable for any shares of the Company's Securities, or
publicly disclose the intention to make any such offer, sale, pledge, disposal
or filing, without the prior written consent of CS First Boston; except:  (i)
issuances of Securities pursuant to the exercise of options outstanding on the
date hereof; (ii) grants of options pursuant to the terms of the Company's 1990
Stock Option Plan and 1994 Directors' Stock Option Plan or issuances of
Securities pursuant to the exercise of such options; (iii) sales of Securities
pursuant to the Company's 1980 Stock Purchase Plan; (iv) issuances of Securities
pursuant to the Company's Stock Bonus Plan; and (v) registration of additional
Securities issuable upon the exercise of options granted under the Company's
1990 Stock Option Plan.

     (i)  The Company agrees with the several Underwriters that it will pay all
expenses incident to the performance of its obligations and the obligations of
the Selling Stockholders under this Agreement, and will reimburse the
Underwriters (if and to the extent incurred by them) for any filing fees and
other expenses (including fees and disbursements of counsel) incurred by them in
connection with qualification of the Offered Securities for sale under the laws
of such jurisdictions as CS First Boston designates and the printing of
memoranda relating thereto, for the filing fee of the National Association of
Securities Dealers, Inc. relating to the Offered Securities, for any transfer
taxes on the sale of the Offered Securities to the Underwriters and for expenses
incurred in distributing preliminary prospectuses and the Prospectus (including
any amendments and supplements thereto) to the Underwriters.  The foregoing
provisions are intended to relieve the Underwriters from the payment of expenses
and costs which the Company has hereby agreed to pay and shall not affect any
agreement which the Company and any Selling Stockholder shall make, or have
made, for the sharing of such expenses and costs.  It is understood that except
as provided in this Section and Section 7, the Underwriters shall pay all of
their own costs and expenses, including fees and disbursements of their counsel,
stock transfer taxes on the resale of any of the Securities by them and any
advertising expenses connected with any offers they make.  It is understood
further that each of the Company and the Underwriters will bear their own costs
in connection with any selling efforts made in connection with the offering of
the Securities.

     (j)  Each Selling Stockholder agrees to deliver to CS First Boston,

properly completed and executed United States Treasury Department Form W-9 (or

     6.   Conditions to the Obligations of the Underwriters.  The obligations of
the several Underwriters to purchase and pay for the Firm Securities on the
First Closing Date and the Optional Securities to be purchased on each Optional
Closing Date will be subject to the accuracy of the representations and
warranties on the part of the Company and the Selling Stockholders herein, to
the accuracy of the statements of Company officers made pursuant to the
provisions hereof, to the performance by the Company and the Selling
Stockholders of their obligations hereunder and to the following additional
conditions precedent:

     (a)  The Representatives shall have received a letter, dated the date of
delivery thereof (which, if the Effective Time of the Initial Registration
Statement is prior to the execution and delivery of this Agreement, shall be on
or prior to the date of this Agreement or, if the Effective Time of the Initial
Registration Statement is subsequent to the execution and delivery of this
Agreement, shall be prior to the filing of the amendment or post-effective
amendment to the registration statement to be filed shortly prior to such
Effective Time), of Ernst & Young LLP confirming that they are independent
public accountants within the meaning of the Act and the applicable Rules and
Regulations and stating to the effect that:

          (i)      in their opinion the financial statements and schedules
     examined by them and included in the Registration Statements comply as to
     form in all material respects with the applicable accounting requirements
     of the Act and the related Rules and Regulations;

          (ii)     they have performed the procedures specified by the American
     Institute of Certified Public Accountants for a review of interim financial
     information as described in Statement of Auditing Standards No. 71, Interim
     Financial Information, on the unaudited financial statements included in
     the Registration Statements;

          (iii)    on the basis of the review referred to in clause (ii) above,
     a reading of the latest available interim financial statements of the
     Company, inquiries of officials of the Company who have responsibility for
     financial and accounting matters and other specified procedures, nothing
     came to their attention that caused them to believe that: (A) the unaudited
     financial statements included in the Registration Statements do not comply
     as to form in all material respects with the applicable accounting
     requirements of the Act and the related Rules and Regulations or any
     material modifications should be made to such unaudited financial
     statements for them to be in conformity with generally accepted accounting
     principles; (B) at the date of the latest available balance sheet read by
     such accountants, or at a subsequent specified date not more than five days
     prior to the date of this Agreement, there was any change in the capital
     stock or any increase in short-term indebtedness or long-term debt of the
     Company and its consolidated subsidiaries or, at the date of the latest
     available balance sheet read by such accountants, there was any decrease in
     consolidated net assets, as compared with amounts shown on the latest
     balance sheet included in the Prospectus; or (C) for the period from the
     closing date of the latest income statement included in the Prospectus to
     the closing date of the latest available income statement read by such
     accountants there were any decreases, as compared with the corresponding
     period of the previous year, in consolidated net sales or net operating
     income or in the total per share amounts of consolidated net income;

                                       12
<PAGE>
 
     except in all cases set forth in clauses (B) and (C) above for changes,
     increases or decreases which the Prospectus discloses have occurred or may
     occur or which are described in such letter; and

          (iv)     they have compared specified dollar amounts (or percentages
     derived from such dollar amounts) and other financial information contained
     in the Registration Statements (in each case to the extent that such dollar
     amounts, percentages and other financial information are derived from the
     general accounting records of the Company and its subsidiaries subject to
     the internal controls of the Company's accounting system or are derived
     directly from such records by analysis or computation) with the results
     obtained from inquiries, a reading of such general accounting records and
     other procedures specified in such letter and have found such dollar
     amounts, percentages and other financial information to be in agreement
     with such results, except as otherwise specified in such letter.

     For purposes of this subsection, (i) if the Effective Time of the Initial
Registration Statement is subsequent to the execution and delivery of this
Agreement, "Registration Statements" shall mean the initial registration
statement as proposed to be amended by the amendment or post-effective amendment
to be filed shortly prior to its Effective Time, (ii) if the Effective Time of
the Initial Registration Statement is prior to the execution and delivery of
this Agreement but the Effective Time of the Additional Registration Statement
is subsequent to such execution and delivery, "Registration Statements" shall
mean the Initial Registration Statement and the additional registration
statement as proposed to be filed or as proposed to be amended by the post-
effective amendment to be filed shortly prior to its Effective Time, and (iii)
"Prospectus" shall mean the prospectus included in the Registration Statements.
All financial statements and schedules included in material incorporated by
reference into the Prospectus shall be deemed included in the Registration
Statements for purposes of this subsection.

     (b)  If the Effective Time of the Initial Registration Statement is not
prior to the execution and delivery of this Agreement, such Effective Time shall
have occurred not later than 10:00 p.m., New York time, on the date of this
Agreement or such later date as shall have been consented to by CS First Boston.
If the Effective Time of the Additional Registration Statement (if any) is not
prior to the execution and delivery of this Agreement, such Effective Time shall
have occurred not later than 10:00 p.m., New York time, on the date of this
Agreement or, if earlier, the time the Prospectus is printed and distributed to
any Underwriter, or shall have occurred at such later date as shall have been
consented to by CS First Boston.  If the Effective Time of the Initial
Registration Statement is prior to the execution and delivery of this Agreement,
the Prospectus shall have been filed with the Commission in accordance with the
Rules and Regulations and Section 5(a) of this Agreement.  Prior to such Closing
Date, no stop order suspending the effectiveness of a Registration Statement
shall have been issued and no proceedings for that purpose shall have been
instituted or, to the knowledge of any Selling Stockholder, the Company or the
Representatives, shall be contemplated by the Commission.

     (c)  Subsequent to the execution and delivery of this Agreement, there
shall not have occurred: (i) any change, or any development or event involving a
prospective change, in the condition (financial or other), business, properties
or results of operations of the Company or

                                       13
<PAGE>
 
its subsidiaries which, in the judgment of a majority in interest of the
Underwriters, including the Representatives, is material and adverse and makes
it impractical or inadvisable to proceed with completion of the offering or the
sale of and payment for the Offered Securities; (ii) any downgrading in the
rating of any debt securities of the Company by any "nationally recognized
statistical rating organization" (as defined for purposes of Rule 436(g) under
the Act), or any public announcement that any such organization has under
surveillance or review its rating of any debt securities of the Company (other
than an announcement with positive implications of a possible upgrading, and no
implication of a possible downgrading, of such rating); (iii) any suspension or
limitation of trading in securities generally on the New York Stock Exchange, or
any setting of minimum prices for trading on such exchange, or any suspension of
trading of any securities of the Company on any exchange or in the over-the-
counter market; (iv) any banking moratorium declared by U.S. Federal or New York
authorities; or (v) any outbreak or escalation of major hostilities in which the
United States is involved, any declaration of war by Congress or any other
substantial national or international calamity or emergency if, in the judgment
of a majority in the interest of the Underwriters, including the
Representatives, the effect of any such outbreak, escalation, declaration,
calamity or emergency makes it impractical or inadvisable to proceed with
completion of the offering or the sale of and payment for the Offered
Securities.

     (d)  The Representatives shall have received an opinion dated such Closing
Date of Pircher, Nichols & Meeks, counsel for the Company, to the effect that:

          (i)      The Company has been duly incorporated and is an existing
     corporation in good standing under the laws of the State of California,
     with corporate power and authority to own its properties and conduct its
     business as described in the Prospectus; and the Company is duly qualified
     to do business as a foreign corporation and is in good standing in all
     other jurisdictions in which its ownership or lease of property or the
     conduct of its business requires such qualification, except for
     jurisdictions in which the failure to so qualify would not have a material
     adverse effect on the financial condition or business prospects of the
     Company and its subsidiaries taken as a whole;

          (ii)     The Firm Securities delivered on such Closing Date and all
     other outstanding shares of the Common Stock of the Company have been duly
     authorized and validly issued and are fully paid and nonassessable; the
     Optional Securities to be delivered on such Closing Date, upon issuance and
     delivery thereof and payment therefor in the manner provided herein will be
     duly authorized, validly issued, fully paid and nonassessable; the Offered
     Securities conform to the description thereof contained in the Prospectus;
     and the stockholders of the Company have no preemptive rights with respect
     to the Securities;

          (iii)    No consent, approval, authorization or order of, or filing
     with, any governmental agency or body or any court is required to be
     obtained or made by the Company for the consummation of the transactions
     contemplated by this Agreement in connection with the sale of the Offered
     Securities, except such as have been obtained and made under the Act and
     such as may be required under state securities laws;

                                       14
<PAGE>
 
          (iv)    The execution, delivery and performance of this Agreement and
     the consummation of the transactions herein contemplated will not result in
     a breach or violation of any of the terms or provisions of, or constitute a
     default under, any statute, rule, regulation or order of any governmental
     agency or body or any court having jurisdiction over the Company or any
     subsidiary of the Company or any of their properties, which such rule,
     regulation, or order is known to such counsel, or any agreement or
     instrument known to such counsel to which the Company or any such
     subsidiary is a party or by which the Company or any such subsidiary is
     bound or to which any of the properties of the Company or any such
     subsidiary is subject, or the charter or bylaws of the Company or any such
     subsidiary (except as rights to indemnification and contribution may be
     limited by federal or state securities laws);

          (v)     The Initial Registration Statement was declared effective
     under the Act as of the date and time specified in such opinion, the
     Additional Registration Statement (if any) was filed and became effective
     under the Act as of the date and time (if determinable) specified in such
     opinion, the Prospectus either was filed with the Commission pursuant to
     the subparagraph of Rule 424(b) specified in such opinion on the date
     specified therein or was included in the Initial Registration Statement or
     the Additional Registration Statement (as the case may be), and, to the
     best of the knowledge of such counsel, no stop order suspending the
     effectiveness of a Registration Statement or any part thereof has been
     issued and no proceedings for that purpose have been instituted or are
     pending or contemplated under the Act, and each Registration Statement and
     the Prospectus, and each amendment or supplement thereto, as of their
     respective or issue dates, complied as to form in all material respects
     with the requirements of the Act and the Rules and Regulations (except for
     the financial statements and other financial data as to which such counsel
     need express no opinion);

          (vi)    The descriptions in the Registration Statements and Prospectus
     of statutes, legal and governmental proceedings and contracts and other
     documents are accurate and fairly present the information required to be
     shown; and such counsel do not know of any legal or governmental
     proceedings required to be described in a Registration Statement or the
     Prospectus which are not described as required or of any contracts or
     documents of a character required to be described in a Registration
     Statement or the Prospectus or to be filed as exhibits to a Registration
     Statement which are not described and filed as required; it being
     understood that such counsel need express no opinion as to the financial
     statements or other financial data contained in the Registration Statements
     or the Prospectus;

          (vii)   This Agreement has been duly authorized, executed and
     delivered by the Company; and

          (viii)  In addition, such counsel shall state that, although they have
     not verified the accuracy or completeness of the statements contained in
     the Initial Registration Statement or the Additional Registration Statement
     (if any) or any amendment to either thereof, nothing has come to the
     attention of such counsel which causes them to believe that any
     Registration Statement or any amendment thereto, as of its effective date
     or as

                                       15
<PAGE>
 
     of such Closing Date (except for the financial statements and other
     financial data as to which such counsel need express no opinion), contained
     any untrue statement of a material fact or omitted to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading or that the Prospectus or any amendment or supplement
     thereto, as of its issue date or as of such Closing Date (except for the
     financial statements and other financial data as to which such counsel need
     express no such opinion), contained any untrue statement of a material fact
     or omitted to state any material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading.

     (e)  The Representatives shall have received an opinion dated the First
Closing Date of Baker & Botts, L.L.P., counsel for Baker Hughes, to the effect
that:

          (i)   Baker Hughes had full right, power and authority to sell,
     assign, transfer and deliver the Firm Securities delivered by it on the
     First Closing Date hereunder; and upon transfer of the Firm Securities to
     be sold by Baker Hughes hereunder to the Underwriters, the Underwriters
     will acquire such Firm Securities free and clear of all adverse claims
     (within the meaning of the Uniform Commercial Code as in effect in the
     State of New York), assuming the Underwriters take delivery in good faith
     and without notice of any adverse claim;

         (ii)   No consent, approval, authorization or order of, or filing with,
     any governmental agency or body or any court is required to be obtained or
     made by Baker Hughes for the consummation of the transactions contemplated
     by this Agreement in connection with the sale by it of the Firm Securities,
     except such as have been obtained and made under the Act and such as may be
     required under state securities laws;

         (iii)  To the knowledge of such counsel, the execution, delivery and
     performance of this Agreement and the consummation of the transactions
     herein contemplated will not result in a breach or violation of any of the
     terms or provisions of, or constitute a default under, any statute, rule or
     regulation of any governmental agency or body having jurisdiction over
     Baker Hughes or any of its properties or the charter or bylaws of Baker
     Hughes; and

     governmental agency or body or any court having jurisdiction over Baker
     Hughes or any of its properties or any agreement or

                                       16

     instrument to which Baker Hughes is a party or by which Baker Hughes is
     bound or to which any of its properties is subject.

     (g)  The Representatives shall have received an opinion dated such Closing
Date of Pircher, Nichols & Meeks, special counsel for Reinhold, to the effect
that:

          (i)    No facts have come to such counsel's attention which causes
     them to believe that Reinhold lacks full legal right, power and authority
     to sell, assign, transfer and deliver the Firm Securities to be sold by him
     hereunder on such Closing Date;

          (ii)   No facts have come to such counsel's attention which causes
     them to believe that Reinhold lacks valid and unencumbered title to the
     Firm Securities to be delivered by him on such Closing Date;

          (iii)  No facts have come to such counsel's attention which causes
     them to believe that upon delivery of the Firm Securities to be sold by
     Reinhold hereunder on such Closing Date and payment therefor in accordance
     with the terms of this Agreement and assuming that the Underwriters who
     have severally purchased such Firm Securities in good faith without notice
     of any adverse claim, such Underwriters will not have marketable title to
     the Firm Securities sold by Reinhold hereunder, free and clear of any
     liens, claims, encumbrances and security interests whatsoever, and that
     such title will not vest in the Underwriters, who have severally purchased
     such Securities hereunder;

          (iv)   No consent, approval, authorization or order of, or filing
     with, any governmental agency or body or any court is required to be
     obtained or made by Reinhold for the consummation of the transactions
     contemplated by this Agreement in connection with the sale by him of the
     Firm Securities, except such as have been obtained and made under the
     Act and such as may be required under state securities laws; and

          (v)    No facts have come to such counsel's attention which causes
     them to believe that the execution, delivery and performance of this
     Agreement and the consummation of the transactions herein contemplated will
     result in a breach or violation of any of the terms or provisions of, or
     constitute a default under, any statute, rule, regulation or order of any
     governmental agency or body or any court having jurisdiction over Reinhold
     or any of his properties or any agreement or instrument to which Reinhold
     is a party or by which Reinhold is bound or to which any of his properties
     is subject (except as rights to indemnification and contribution may be
     limited by federal or state securities laws).

     (h)  The Representatives shall have received from Latham & Watkins, special
counsel for the Underwriters, such opinion or opinions, dated such Closing Date,
with respect to the incorporation of the Company, the validity of the Offered
Securities delivered on such Closing Date, the Registration Statements, the

     (i)  The Representatives shall have received a certificate, dated such
Closing Date, of the President or any Vice-President and a principal financial

warranties of the Company in this Agreement are true and correct; the Company
has complied with all agreements and satisfied all conditions on its part to be
performed or satisfied hereunder at or prior to such Closing Date; no stop order
suspending the effectiveness of any Registration Statement has been issued and
no proceedings for that purpose have been instituted or are contemplated by the
Commission; the Additional Registration Statement (if any) satisfying the
requirements of subparagraphs (1) and (3) of Rule 462(b) was filed pursuant to
Rule 462(b), including payment of the applicable filing fee in accordance with
Rule 111 under the Act, prior to the time the Prospectus was printed and
distributed to any Underwriter; and, subsequent to the date of the most recent
financial statements in the Prospectus, there has been no material adverse
change, nor any development or event involving a prospective material adverse
change, in the condition (financial or other), business, properties or results
of operations of the Company and its subsidiaries taken as a whole, except as
set forth or contemplated by the Prospectus or as described in such certificate.

     (j)  The Representatives shall have received a letter dated such Closing
Date of Ernst & Young LLP which meets the requirements of subsection (a) of this
Section, except that the specified date referred to in such subsection will be a

Each Selling Stockholder and the Company will furnish the Representatives with
such conformed copies of such opinions, certificates, letters and documents as
the Representatives reasonably request.  CS First Boston may in its sole
discretion waive on behalf of the Underwriters compliance with any conditions to
the obligations of the Underwriters hereunder, whether in respect of an Optional
Closing Date or otherwise.

     7.   Indemnification and Contribution.  (a) The Company will indemnify and
hold harmless each Underwriter and Reinhold against any losses, claims, damages
or liabilities, joint or several, to which such Underwriter or Reinhold may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement, the Prospectus, or any amendment or
supplement thereto, or any related preliminary prospectus, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse such Underwriter or Reinhold for any legal or
other expenses reasonably incurred by such Underwriter or Reinhold in connection
with investigating or defending any such loss, claim, damage, liability or
action as such expenses are incurred, notwithstanding the possibility that
payments for such expenses might later be held to be improper, in which case the
person receiving them shall promptly refund them to the Company; provided,
however, that the Company will not be liable in any such case to the extent that
any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement in or omission or alleged omission
from any such documents in reliance upon and in conformity with written

<PAGE>
 
Representatives specifically for use therein, it being understood and agreed
that the only such information furnished by any Selling Stockholder or by any
Underwriter consists of the information described as such in subsection (b), (c)
or (d) below, as applicable; provided, further, that the indemnity contained in
this subsection (a) with respect to any preliminary prospectus shall not inure
to the benefit of any Underwriter from whom the person asserting a loss, claim,

preliminary prospectus purchased Offered Securities which are the subject
thereof if the Prospectus corrected such untrue statement or omission and if
such Underwriter failed to send a copy of the Prospectus as the same was
supplemented or amended to such person at or prior to the written confirmation
of the sale of the Offered Securities to such person as required by the Act.

     (b)  Subject to the limitations set forth below, Reinhold will indemnify
and hold harmless the Company and each Underwriter against any losses, claims,
damages or liabilities, joint or several, to which the Company or such
Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, the Prospectus, or any
amendment or supplement thereto, or any related preliminary prospectus, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with information furnished
to the Company or the Underwriters by Reinhold specifically for use therein, it
being understood and agreed that the only such information furnished by Reinhold
consists of the information concerning Reinhold contained in the Prospectus
under the caption "Selling Shareholders," and Reinhold will reimburse such
Underwriter or the Company for any legal or other expenses reasonably incurred
by such Underwriter or the Company in connection with investigating or defending
any such loss, claim, damage, liability or action as such expenses are incurred,
notwithstanding the possibility that payments for such expenses might later be
held to be improper, in which case the person receiving them shall promptly
refund them to Reinhold; provided, further, that the indemnity contained in this
subsection (b) with respect to any preliminary prospectus shall not inure to the
benefit of any Underwriter from whom the person asserting a loss, claim, damage
or liability arising from an untrue statement or omission in any preliminary
prospectus purchased Offered Securities which are the subject thereof if the
Prospectus corrected such untrue statement or omission and if such Underwriter
failed to send a copy of the Prospectus as the same was supplemented or amended
to such person at or prior to the written confirmation of the sale of the
Offered Securities to such person as required by the Act. The aggregate
liability of Reinhold under this indemnity agreement shall not exceed the
proceeds received by him in connection with the sale of his Firm Shares.

     (c)  Baker Hughes will indemnify and hold harmless each Underwriter against
any losses, claims, damages or liabilities, joint or several, to which such
Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, the Prospectus, or any
amendment or supplement thereto, or any related preliminary prospectus, or arise
out of or are

                                       19
<PAGE>
 
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with information furnished to the Company or
the Underwriters by Baker Hughes specifically for use therein, it being
understood and agreed that the only such information furnished by Baker Hughes
consists of the information concerning Baker Hughes in the Prospectus under the
caption "Selling Shareholders"; and will reimburse each Underwriter for any
legal or other expenses reasonably incurred by such Underwriter in connection
with investigating or defending any such loss, claim, damage, liability or
action as such expenses are incurred, notwithstanding the possibility that
payments for such expenses might later be held to be improper, in which case the
person receiving them shall promptly refund them to Baker Hughes; provided,
however, that the indemnity contained in this subsection (c) with respect to any
preliminary prospectus shall not inure to the benefit of any Underwriter from
whom the person asserting a loss, claim, damage or liability arising from an
untrue statement or omission in any preliminary prospectus purchased Offered
Securities which are the subject thereof if the Prospectus corrected such untrue
statement or omission and if such Underwriter failed to send a copy of the
Prospectus as the same was supplemented or amended to such person at or prior to
the written confirmation of the sale of the Offered Securities to such person as
required by the Act. The aggregate liability of Baker Hughes under this
indemnity agreement shall not exceed the proceeds received by it in connection
with the sale of its Firm Shares.

     (d)  Each Underwriter will severally and not jointly indemnify and hold
harmless the Company and the Selling Stockholders against any losses, claims,
damages or liabilities to which the Company or the Selling Stockholders may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement, the Prospectus, or any amendment or
supplement thereto, or any related preliminary prospectus, or arise out of or
are based upon the omission or the alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein

untrue statement or alleged untrue statement or omission or alleged omission was
made in reliance upon and in conformity with written information furnished to
the Company by such Underwriter through the Representatives specifically for use
therein, and will reimburse any legal or other expenses reasonably incurred by
the Company and the Selling Stockholders in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses are
incurred, notwithstanding the possibility that payments for such expenses might
later be held to be improper, in which case the person receiving such payments
shall promptly refund them to such Underwriter, it being understood and agreed
that the only such information furnished by any Underwriter consists of the
following information in the Prospectus furnished on behalf of each Underwriter:
the last paragraph at the bottom of the cover page concerning the terms of the
offering by the Underwriters, the legends concerning over-allotments and
stabilization and regarding transactions by certain affiliated persons on the
inside front cover page and the concession and reallowance figures appearing in
the fourth paragraph under the caption "Underwriting."

     (e)  Promptly after receipt by an indemnified party under this Section of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be

                                       20
<PAGE>
 
made against an indemnifying party under subsection (a), (b), (c) or (d) above,
notify the indemnifying party of the commencement thereof; but the omission so
to notify the indemnifying party will not relieve it from any liability which it
may have to any indemnified party otherwise than under subsection (a), (b), (c)
or (d) above.  In case any such action is brought against any indemnified party
and it notifies an indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and, to the extent
that it may wish, jointly and with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof, other than
reasonable costs of investigation.  No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on any claims that are the subject
matter of such action.

     (f)  If the indemnification provided for in this Section is unavailable or
insufficient to hold harmless an indemnified party under subsection (a), (b),
(c) or (d) above, then each indemnifying party shall contribute to the amount
paid or payable by such indemnified party as a result of the losses, claims,
damages or liabilities referred to in subsection (a), (b), (c) or (d) above (i)
in such proportion as is appropriate to reflect the relative benefits received
by the Company and the Selling Stockholders, on the one hand, and the
Underwriters, on the other hand, from the offering of the Securities, or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company, the
Selling Stockholders and the Underwriters in connection with the statements or
omission which resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations.  The relative benefits received
by the Company and the Selling Stockholders, on the one hand, and the
Underwriters, on the other hand, shall be deemed to be in the same proportion as
the total net proceeds from the offering (before deducting expenses) received by
the Selling Stockholders and the Company bear to the total underwriting discount
and commissions received by the Underwriters.  The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, the Selling
Stockholders or the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such untrue
statement or omission.  The amount paid by an indemnified party as a result of
the losses, claims, damages or liabilities referred to in the first sentence of
this subsection (f) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any action or claim which is the subject of this subsection (f).
Notwithstanding the provisions of this subsection (f), (i) no Underwriter shall
be required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount

                                       21
<PAGE>
 
of any damages which such Underwriter has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission, and (ii) no Selling Stockholder shall be required to contribute any
amount in excess of the amount by which the net proceeds received by it or him
exceeds the amount of any damages that such Selling Stockholder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations in this subsection (f) to
contribute are several in proportion to their respective underwriting
obligations and not joint.  The obligations of each of the Selling Stockholders
under this subsection (f) to contribute are several in proportion to the total
proceeds received by it or him and are not joint.

     (g)  The obligations of the Company and the Selling Stockholders under this
Section shall be in addition to any liability which the Company and the Selling
Stockholders may otherwise have and shall extend, upon the same terms and
conditions, to each person, if any, who controls any Underwriter within the
meaning of the Act; and the obligations of the Underwriters under this Section
shall be in addition to any liability which the respective Underwriters may
otherwise have and shall extend, upon the same terms and conditions, to each
director of the Company, to each officer of the Company who has signed a
Registration Statement, to each person, if any, who controls the Company within
the meaning of the Act, and to each person, if any, who controls a Selling
Stockholder within the meaning of the Act.

     8.   Default of Underwriters.  If any Underwriter or Underwriters default
in their obligations to purchase Offered Securities hereunder on either the
First Closing Date or any Optional Closing Date and the aggregate number of
shares of Offered Securities that such defaulting Underwriter or Underwriters
agreed but failed to purchase does not exceed 10% of the total number of shares
of Offered Securities that the Underwriters are obligated to purchase on such
Closing Date, CS First Boston may make arrangements satisfactory to Baker Hughes
(in the case of a default with respect to the Firm Securities) or the Company
(in case of default with respect to the Optional Securities) for the purchase of
such Offered Securities by other persons, including any of the Underwriters, but
if no such arrangements are made by such Closing Date, the non-defaulting
Underwriters shall be obligated severally, in proportion to their respective
commitments hereunder, to purchase the Offered Securities that such defaulting
Underwriters agreed but failed to purchase on such Closing Date.  If any
Underwriter or Underwriters so default and the aggregate number of shares of
Offered Securities with respect to which such default or defaults occur exceeds
10% of the total number of shares of Offered Securities that the Underwriters
are obligated to purchase on such Closing Date and arrangements satisfactory to
CS First Boston and Baker Hughes (in the case of a default with respect to the
Firm Securities) or the Company (in case of default with respect to the Optional
Securities) for the purchase of such Offered Securities by other persons are not
made within 36 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter, the Company or the
Selling Stockholders, except as provided in Section 9 (provided that if such
default occurs with respect to Optional Securities after the First Closing Date,
this Agreement will not terminate as to the Firm Securities or any Optional
Securities purchased prior to such termination).  As used in this Agreement, the
term "Underwriter"

                                       22
<PAGE>
 
includes any person substituted for an Underwriter under this Section.  Nothing
herein will relieve a defaulting Underwriter from liability for its default.

     9.   Survival of Certain Representations and Obligations.  The respective
indemnities, agreements, representations, warranties and other statements of the
Selling Stockholders, of the Company or its officers and of the several
Underwriters set forth in or made pursuant to this Agreement will remain in full
force and effect, regardless of any investigation, or statement as to the
results thereof, made by or on behalf of any Underwriter, any Selling
Stockholder, the Company or any of their respective representatives, officers or
directors or any controlling person, and will survive delivery of and payment
for the Offered Securities.  If this Agreement is terminated pursuant to Section
8 or if for any reason the purchase of the Offered Securities by the
Underwriters is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company, the Selling Stockholders, and the Underwriters
pursuant to Section 7 shall remain in effect, and if any Offered Securities have
been purchased hereunder the representations and warranties in Section 2 and all
obligations under Section 5 shall also remain in effect.  If the purchase of the
Offered Securities by the Underwriters is not consummated for any reason other
than solely because of the termination of this Agreement pursuant to Section 8
or the occurrence of any event specified in clause (iii), (iv) or (v) of Section
6(c), the Company will reimburse the Underwriters for all out-of-pocket expenses
(including fees and disbursements of counsel) reasonably incurred by them in
connection with the offering of the Offered Securities.

     10.  Notices.  All communications hereunder will be in writing and, if sent
to the Underwriters, will be mailed, delivered or telegraphed and confirmed to
the Representatives, c/o CS First Boston Corporation, Park Avenue Plaza, New
York, New York 10055, Attention:  Investment Banking Department -- Transactions

and confirmed to him at 743 North Eckhoff Street, Orange, California 92668;
provided, however, that any notice to an Underwriter pursuant to Section 7 will
be mailed, delivered or telegraphed and confirmed to such Underwriter.

     11.  Successors.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective personal representatives
and successors and the officers and directors and controlling persons referred
to in Section 7, and no other person will have any right or obligation
hereunder.

     12.  Representation.  The Representatives will act for the several
Underwriters in connection with the transactions contemplated by this Agreement,
and any action under this Agreement taken by the Representatives jointly or by
CS First Boston will be binding upon all the Underwriters.  In the case of any
executive officer or director of the Company who has agreed for a period
following the date of the Prospectus not to sell, contract to sell or otherwise
dispose of any shares of Common Stock of the Company owned by them, directly or
indirectly,

                                       23
<PAGE>
 
without the written consent of the Underwriters, CS First Boston shall have the
authority to give such consent on the behalf of the Representatives and the
Underwriters.

     13.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

     14.  APPLICABLE LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES
OF CONFLICTS OF LAWS.

     THE COMPANY AND EACH SELLING STOCKHOLDER HEREBY SEVERALLY SUBMIT TO THE
NON-EXCLUSIVE JURISDICTION OF THE FEDERAL AND STATE COURTS IN THE BOROUGH OF
MANHATTAN IN THE CITY OF NEW YORK IN ANY SUIT OR PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

                                       24
<PAGE>
 
     If the foregoing is in accordance with the Representatives' understanding
of our agreement, kindly sign and return to the Company one of the counterparts
hereof, whereupon it will become a binding agreement among the Selling
Stockholders, the Company and the several Underwriters in accordance with its
terms.

                                     Very truly yours,

Varco International, Inc.
743 North Eckhoff Street
Orange, California 92668

Gentlemen:

          We are acting as counsel to Varco International, Inc., a California
corporation (the "Company"), in connection with the registration under the
Securities Act of 1933, as amended (the "Securities Act") of 7,585,447 shares of
the Common Stock of the Company, consisting of (i) 6,346,041 shares (the "Baker
Hughes Shares") to be offered and sold by Baker Hughes Incorporated, (ii)
250,000 shares (the "Reinhold Shares" and, together with the Baker Hughes
Shares, the "Firm Shares") to be offered and sold by Walter B. Reinhold, and
(iii) 989,406 shares (the "Optional Shares") to be subject to an over-allotment
option to be granted by the Company to the Underwriters of the proposed offering
pursuant to a Registration Statement on Form S-3 (No. 333-02869), filed by the
Company with the Securities and Exchange Commission (the "Commission") on April
26, 1996, Amendment No. 1 thereto as filed with the Commission on May 3, 1996,
Amendment No. 2 thereto as filed with the Commission on May 3, 1996, and
Amendment No. 3 thereto to be filed with the Commission on May 17, 1996 (as so
amended, the "Registration Statement").

          We have examined originals, or copies certified or otherwise
identified to our satisfaction, of such documents, corporate records and other
instruments as we have deemed necessary for the purposes of this opinion.

          Based upon the foregoing, we are of the opinion that, upon the
effectiveness of the Registration Statement:

          1. The Firm Shares constitute legally issued, fully paid and
nonassessable shares of the Common Stock of the Company.
<PAGE>
 
          2.  The Optional Shares, upon issuance and delivery thereof and
payment therefor as contemplated by the prospectus included in the Registration
Statement and upon approval by the Board of Directors of the Company or the
special Executive Committee appointed for such purpose by such Board of the
price to be paid to the Company for the Optional Shares (to be reflected in the
prospectus to be included in the Registration Statement at the time it becomes
effective or the prospectus to be filed by the Company pursuant to Rule 424(b)
and Rule 430A under the Securities Act) will constitute legally issued, fully
paid and nonassessable shares of the Common Stock of the Company.

          We hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement and to the references to us under the caption "Legal
Opinions" in the prospectus which constitutes part of the Registration
Statement.

                                       Very truly yours,
