                            NONCOMPETITION AGREEMENT

         This Noncompetition Agreement ("Agreement") is entered into between IRI
International Corporation ("IRI"), a Delaware corporation having offices at 1000
Louisiana, Suite 5900, Houston, Texas 77002, and Hushang Ansary, its Chairman
and Chief Executive Officer ("Ansary"), to be effective as hereinafter provided.

                                    RECITAL:

         A.       IRI is party to an Agreement of Merger of even date herewith
among itself, Arrow Acquisition, Inc. and National-Oilwell, Inc. ("Oilwell")
(the "Merger Agreement").

         For and in consideration of the mutual promises, covenants, and
obligations contained herein, IRI and Ansary agree as follows:

1.       TERM OF THIS AGREEMENT.

         1.1.     The term of this Agreement shall be for three (3) years from
the Closing Date (as such term is defined in the Merger Agreement).

2.       NON-COMPETITION OBLIGATIONS.

         2.1.     In consideration for the amounts to be paid to Ansary
hereunder, IRI and Ansary agree to the non-competition provisions of this
Article 2. Ansary agrees that during the term of this Agreement, he will not,
directly or indirectly for himself or for others, in any county within the State
of Texas, and to the extent allowed by law, in any geographic area or market
where IRI or any of its subsidiaries or affiliated companies are engaged in the
Relevant Business as of Closing Date or have during the previous twelve months
engaged in the Relevant Business:

         (i)      engage in the business of the design, manufacture, sale,
                  repair and distribution of products used in oil and gas
                  drilling and production or any other business; in either case
                  if engaged in by Oilwell immediately prior to the Closing Date
                  (the "Relevant Business");

         (ii)     render services to any other person, association, or entity
                  who is engaged, directly or indirectly, in the Relevant
                  Business; and

         (iii)    induce any employee of IRI or any of its subsidiaries or
                  affiliates to terminate his or her employment with IRI or any
                  of its subsidiaries or affiliates, or initiate or assist in
                  the hiring of any such employee by any person, association, or
                  entity not affiliated with IRI or any of its subsidiaries or
                  affiliates; provided, however, that
<PAGE>   2
                  this clause (iii) shall not apply to responses to general
                  advertising not directed toward employees of IRI or any of its
                  subsidiaries or affiliates.

These non-competition obligations shall apply only to businesses having annual
revenues in excess of $___ million competitive with any line of business
conducted by Oilwell or any of its subsidiaries having annual revenues in excess
of $___ million for the most recent fiscal year. If Oilwell or any of its
subsidiaries or affiliates abandons a particular aspect of its business, that
is, ceases such aspect of its business with the intention to permanently refrain
from such aspect of its business, then this non-competition covenant shall not
apply to such former aspect of that business.

         2.2.     Ansary acknowledges that money damages would not be sufficient
remedy for any breach of this Article 2 by him, and IRI or any of its
subsidiaries or affiliates shall be entitled to enforce the provisions of this
Article 2 specific performance and injunctive relief as remedies for such breach
or any threatened breach. Such remedies shall not be deemed the exclusive
remedies for a breach of this Article 2, but shall be in addition to all
remedies available at law or in equity to IRI or any of its subsidiaries or
affiliates, including, without limitation, the recovery of damages from Ansary.

         2.3.     It is expressly understood and agreed that IRI and Ansary
consider the restrictions contained in this Article 2 to be reasonable to
protect the proprietary information of IRI and its subsidiaries and affiliates.
Nevertheless, if any of the aforesaid restrictions are found by a court having
jurisdiction to be unreasonable, or overly broad as to geographic area or time,
or otherwise unenforceable, the parties intend for the restrictions therein set
forth to be modified by such courts so as to be reasonable and enforceable and,
as so modified by the court, to be fully enforced.

3.       PAYMENTS

         3.1.     In consideration for Ansary's non-competition agreement set
forth herein, IRI agrees to pay to Ansary $3 million, payable $1 million on the

without deduction for any and all taxes or withholdings as legally allowed.

4.       MISCELLANEOUS ASSETS
