provided, however, (i) that Buyer and its representatives shall take such

Company and the Subsidiaries, (ii) the Company and the Subsidiaries shall not 
be required to take any action which would constitute a waiver of the

     5.3     Efforts.  Subject to the terms and conditions of this Agreement, 
each of the parties hereto shall use commercially reasonable efforts to take, 
or cause to be taken, all action, and to do, or cause to

be done, all things necessary, proper or advisable under applicable laws and

all licenses, permits, authorizations, consents and approvals of all third 
parties and governmental authorities necessary in connection with the 
consummation of the transactions contemplated by this Agreement prior to the 
Closing.  Sellers shall not, however, have any obligation to pay any fee to 
any third party for the purpose of obtaining any consent or approval or any 
costs and expenses of any third party resulting from the process of obtaining 
such consent or approval.  Each of the parties hereto shall make or cause to 
be made all filings and submissions under laws and regulations applicable to 
it as may be required for the consummation of the transactions contemplated by

other in exchanging such information and assistance as any of the parties

public statement with respect to this Agreement and the transactions 
contemplated hereby without prior consultation with and approval of the other

discharge its disclosure obligations, in which case such party nevertheless 
shall advise the other party and discuss the contents of the disclosure before

                                   -------------------
matter hereafter arising which, if existing as of the date of this Agreement, 
would have been required to be set forth or described in the Disclosure

Schedule.

     5.8     Access to Books and Records Following the Closing Following the 
Closing.  Buyer shall, and shall cause the Company and the Subsidiaries to, 
permit Sellers and their authorized representatives, during normal business 
hours and upon reasonable notice, to have reasonable access to, 

                                       -22-


and examine and make copies of, all books and records of the Company and the 
Subsidiaries which relate to transactions or events occurring prior to the 
Closing or transactions or events occurring subsequent to the Closing which 
are related to or arise out of transactions or events occurring prior to the 
Closing.  Buyer agrees that it shall retain all such books and records for a 
period of seven years, or for a longer period if required by law, following 
the Closing.

     5.9     No Other Bids.  Until the first to occur of the Closing or the 
termination of this Agreement pursuant to Section IX hereof, the Sellers, the 
Parents and the Company shall not, and Sellers, Parents and the Company shall 
not authorize or permit any affiliate, officer, director or employee of, or 
any investment banker, attorney, accountant or other representative retained 
by, Sellers and Parents or the Company to, (a) entertain, encourage, solicit 
or initiate any inquiries or the making of any proposal that may reasonably be 
expected to lead to any proposal to purchase any of the Interests, and of the 
Shares or the Company or (b) participate in any discussions or negotiations, 
or provide third parties with any information relating to any such inquiry or 
proposal.  The Company, Sellers and Parents shall reasonably promptly advise 
Buyer of any such inquiries or proposals received by them.

     5.10     No Competition.  In consideration of the purchase of the 
Interests, and all of the other promises and covenants contained herein, each 
of Sellers and Parents agree that for a period commencing upon the Closing and 
ending upon the fifth anniversary thereof they shall not directly or 
indirectly, alone or with others, engage in any business conducted by the 
Company and the Subsidiaries at the Closing, except for (i) those businesses 
(other than the Company and the Subsidiaries) owned by Sellers at Closing in 
any geographic area in which the Company and the Subsidiaries do business at 
Closing in competition with Buyer, the Company or the Subsidiaries, (ii) any 
activities by either Parent or its affiliates in the manufacture, distribution 
and sale of carbon steel, stainless steel, specialty steel or other products 
manufactured by either Parent or its affiliates, including, but not limited 
to, the manufacture, sale and distribution of oil country tubular goods, 
standard and line pipe or drill pipe, and (iii) any joint venture, partnership 
or other contract, agreement or arrangement by Marathon Oil Company, Delhi Gas 
Pipeline Corporation or other affiliate of USX for the purchase or use (but 
not for resale) of any product or service manufactured, distributed, sole or 
provided by Buyer, the Company or any Subsidiary.  Further, Sellers and 
Parents shall not, unless required by subpoena or other process by any 
Government Authority, during such period and in such geographic locations, 
divulge, communicate, use to the detriment of Buyer, the Company or the 
Subsidiaries or for the benefit of any person or organization, any 
confidential information or trade secrets of the Company's and the 
Subsidiaries' businesses.  Nothing herein shall commit Buyer, the Company or 
the Subsidiaries, on the one hand, or any Parent, Seller or affiliate thereof, 
on the other hand, to engage in any transaction or enter into any 
                                        -23-


agreement or contract other than as contained in or contemplated by any 
contract or agreement existing between them as of the Closing Date.  The 
parties believe this is a reasonable and necessary restriction for purposes of 
protecting the goodwill and other business interest purchased by Buyer, which 
includes Buyer's expectation of expanding its business throughout the world 
without competition from Sellers and Parents for such period; and provided 
further, that the parties agree that the world is a reasonable competitive 
restriction.  Sellers or Parents agree that a breach or violation of this 
covenant not to compete by such Seller or Parent shall entitle Buyer, as a 
matter of right, to an injunction, without necessity of posting bond, issued 
by any court of competent jurisdiction, restraining any further or continued 
breach or violation of this covenant.  Such right to an injunction shall be 
cumulative and in addition to, and not in lieu of, any other remedies to which 
Buyer may show itself justly entitled.  In the event that a Court should 
determine that any restriction herein is unenforceable, the parties, agree 
that this Agreement shall nevertheless be enforceable for the maximum term and 
maximum geographical area allowable by law.  Without limiting the foregoing, 
this covenant shall be enforceable by the remedy of specific performance, 
injunction, and/or damages.  The parties specifically agree that the remedy of 
damages alone is inadequate.

     5.11     Agreement Concerning Employees.  Sellers and Parents agree that 
they shall not directly, or indirectly through a future subsidiary, affiliate 
or otherwise, hire, retain, employ or otherwise provide compensation for or to 
(a) through the first anniversary of the Closing Date, any employee of the 
Company or any Subsidiary who was employed by the Company or any Subsidiary on 
the date hereof or the Closing Date or (b) through the third anniversary of 
the Closing Date, any officer of the Company or any Subsidiary who was 
employed by the Company or such subsidiary or the date hereof or the Closing 
Date, in either such case without the prior written consent of Buyer and 
excluding benefits due any such person under any pension or employee benefit 
plan of either Parent.  Buyer agrees that any remedy at law for any actual or 
threatened breach of the provisions of this Section 5.11 would be inadequate 
and that Buyer shall be entitled to specific performance thereof of injunctive 
relief, or both, by temporary or permanent injunction or such other 
appropriate judicial remedy, writ or order as may be entered by a court of 
competent jurisdiction.  Any such remedy shall be in addition to any damages 
that Buyer may be legally entitled to recover as a result of any breach by 
Sellers or Parents of any provisions of this Section 5.11.

     5.12     Potential Acquisition.  Buyer shall be permitted to pursue, at 
Buyer's cost, the acquisition of Continental Emsco Company utilizing the 
management of the Company (without reimbursing the Company for services of 
such management personnel).  Buyer shall be permitted to disclose to The LTV 
Corporation, Continental Emsco Company, SCF Partners of Houston, their 

                                       -24-

representatives and such other parties as Sellers may reasonably approve, that 
Buyer and Sellers have entered into this Agreement for the acquisition of the 
Company.

     5.13     No Recording.  Prior to the Closing, Buyer shall not record this 
Agreement or any memorandum hereof in any real property, intellectual property 
or other title registration records.

     5.14     Financing.  Buyer shall use commercially reasonable efforts to 
consummate the Financing Commitments.  Buyer shall deliver to Sellers copies 
of all agreements and commitment letters entered into by Buyer pursuant to the 
Financing Commitments and shall keep Sellers informed of material developments 
concerning the Financing Commitments.  Buyer shall use commercially reasonable 
efforts to arrange for Sellers to speak with the other parties to the 
Financing Commitments.  Parents and Sellers shall use commercially reasonable 
efforts to cooperate with Buyer in obtaining the Financing Commitments and 
consummating the financings contemplated thereunder.

     5.15     Environmental Study.  The Company, at its own cost and expense, 
shall commission an environmental study of the Company and the Subsidiaries by

indemnify the Buyer Indemnified Parties pursuant to Sections 6.1(d), 10.3 and 
10.4 above.

     10.7     Conditions of Indemnification.  The obligations and liabilities 
of Sellers, Parents and Buyer with respect to demands, claims, actions, causes

the indemnification provisions of this Agreement shall be subject to the 
following terms and conditions:

     (a)     The indemnified party shall give the indemnifying party prompt 
notice of any such Claim, and if the indemnifying party does not dispute its 
obligation to indemnify the indemnified party hereunder and confirms same in 
writing, the indemnifying party shall have the right to undertake the defense 
thereof by representatives chosen by it;

     (b)     Unless and until the indemnifying party assumes the defense of a 
Claim as provided in subparagraph (a) above, the indemnified party shall have 
the right to undertake the defense, compromise or settlement of such Claim on 
behalf of and for the account and risk of the indemnifying party, subject to 
the right of the indemnifying party (provided that it does not dispute its 
liability to the indemnified party hereunder for such Claim) to assume the 
defense of such Claim at any time prior to settlement, compromise or final 
determination thereof; and

     (c)     Anything in this Article X to the contrary notwithstanding, 
(i) if there is a reasonable probability that a Claim may materially and 
adversely affect the indemnified party other than as a result of money damages 
or other money payments, the indemnified party shall have the right, at its 
own cost and expense, to participate in the defense of such Claim, and 
(ii) the indemnifying party shall not, without the written consent of the 
indemnified party, settle or compromise any Claim or consent to the entry of 
any judgment which does not include as an unconditional term thereof the 
giving by the claimant or the plaintiff to the indemnified party of an 
unconditional release from all liability in respect to such Claim.

     (d)     Notwithstanding any provision herein to the contrary, failure of 
the indemnified party to give notice required by this Section 10.7 shall not 
constitute a waiver of the indemnified party's right to indemnification or a 
defense to any indemnification claim by such indemnified party, except to the 
extent such failure prejudices the ability of the indemnifying party to defend 
against such Claim.
                                       -38-


     (e)     The indemnified party shall reasonably cooperate with the 
indemnifying party, including making available to the indemnifying party all 
records, documents, and other things, making available all employees 
reasonably necessary to investigate, defend and settle such matter, access to 
the Company's or the Subsidiary's properties without cost to the indemnifying 
party other than reimbursement of out-of-pocket expenses actually incurred.

     10.8     Parent Guarantee.  Armco hereby agrees to unconditionally and 
absolutely guarantee the due and punctual performance by National Supply of 
all of National Supply's obligations hereunder subject to a maximum amount 
equal to the total consideration paid by Buyer to National Supply hereunder; 
provided, however that such limitation shall not apply to the obligations of 
National Supply under Section 6.1(d).  USX hereby agrees to unconditionally 
and absolutely guarantee the due and punctual performance by Oilwell of all of 
Oilwell's obligations hereunder subject to a maximum amount equal to the total

limitation shall not apply to the obligations of Oilwell under Section 6.1(d).  
Armco and USX agree that this guarantee shall survive and be enforceable 
notwithstanding any merger, dissolution, bankruptcy or insolvency of National 
Supply or Oilwell, as the case may be.

allocating responsibility under the various indemnities contained in this 
Article X and notwithstanding anything herein to the contrary, (a) the 
disclosure in the Disclosure Schedule of a contract or agreement for the sale
                  -------------------

lawsuits, claims or demands that are or have been made pursuant to such 
contract or agreement; (b) the sale of products or services arising out of the 
conduct by the Company or any Subsidiary of the distribution, tubular, pump, 
drilling business and other activities conducted by such entities on the date

purposes of Sections 10.3(e) and 10.4(e)), even if the Company or a Subsidiary 
owns but does not currently operate the facility that manufactured, sold or 
distributed the product or service involved ; (c) the manufacture of wellhead 
products, sucker rods, hydraulic equipment and pumps, down-hole sucker rod 
pumps, ball valves for fluid control and centrifugal pumps, and the threading

10.4(e), provided that the sale by the Company or any Subsidiary of such items 
manufactured by third parties shall, to the extent conducted by the Company or 
any Subsidiary on the date hereof, constitute ongoing activities of the 
Company and the Subsidiaries.

     Re:  Purchase Agreement ("Purchase Agreement") dated September 22, 1995 
for the Acquisition of National-Oilwell

Gentlemen:

     This letter sets forth agreements that we have reached with respect to 
certain matters contained in the Purchase Agreement as follows:

     1.     The Purchase Agreement reflects that NOW, Holdings, Inc., a 
Delaware corporation ("Holdings"), is the Buyer.  As permitted by Section 11.5 
of the Purchase Agreement, Holdings has assigned its rights as Buyer under the 
Purchase Agreement to National-Oilwell, Inc., a Delaware corporation ("GP"), 
NATOIL, a Delaware corporation ("LP"), and NOW International, Inc., a Delaware 
corporation ("International"), and GP, LP and International shall be entitled 
to all of the rights of Buyer under the Purchase Agreement and shall assume 
and perform all of Buyer's obligations under the Purchase Agreement.  In 
addition, from and after the closing, the term Buyer shall mean collectively, 
Holdings, GP, International and the Company and each of Holdings, GP, 
International, the Company shall be entitled to all of the rights of Buyer 
under the Purchase Agreement and shall perform all of Buyer's obligations 
under the Purchase Agreement.

     2.     The Purchase Agreement also reflects that Buyer will purchase from 
Sellers and Sellers shall assign and transfer to Buyer all of the general 
partnership interest in National-Oilwell, a Delaware general partnership.  At 
the request of Buyer, Sellers have converted National-Oilwell into a Delaware 
limited partnership under the name of National-Oilwell, L.P. by executing an 
amendment to the Partnership Agreement of National-Oilwell in the form of 
Exhibit A attached hereto and by executing and filing with the Delaware 
Secretary of State of Certificate of Limited Partnership of National-Oilwell, 
L.P. in the form of Exhibit B attached hereto.  At closing, Sellers shall 
assign and transfer to LP all of their interest as a limited partner in 
National-Oilwell, L.P. and 



Messrs. Gedeon and Harmer

admit LP as a limited partner of National-Oilwell, L.P., and shall then assign 
and transfer all of their interest as a general partner in National-Oilwell, 
L.P. to GP and withdraw as partners from National-Oilwell, L.P.  All costs of 
filing the Certificate of Limited Partnership shall be borne by Buyer.  Buyer 
may, at its sole cost, cause the limited partnership to be qualified to do 
business in such jurisdictions as the Buyer desires.  In the event that the 
Closing does not occur, for whatever reason, Buyer shall reimburse Sellers all 
costs reasonably incurred in re-establishing the Company as a Delaware general 
partnership.  The assignments referred to in this paragraph 2 shall be in the 
form of Exhibits C-2 through C-4 attached hereto.

     3.     The Purchase Agreement also reflects that Buyer will purchase from 
Sellers and Sellers will assign and transfer to Buyer all of the issued and 
outstanding capital stock of National-Oilwell Pty, Ltd., an Australian 
corporation ("NOW Australia"), and National-Oilwell, Pte. Ltd., a Singapore 
corporation ("NOW Singapore").  At closing, Sellers shall assign and transfer 
to International all of the issued and outstanding capital stock of NOW 
Australia and NOW Singapore.

     4.     The form of Subordinated Note attached as Exhibit L to the 
Purchase Agreement shall be amended to reflect the new structure set forth in 
this Letter Agreement and the fact that National-Oilwell, L.P. will be the 
Borrower under the debt financing documents.  The form of the new Subordinated 
Note is attached hereto as Exhibit D.

     5.     Section 3.3 of the Purchase Agreement is amended and restated to 
read in its entirety as set forth below:

                    "3.3 ORGANIZATION AND QUALIFICATION OF THE COMPANY.  Until 
the conversion of the Company into a limited partnership, the Company was (a) 
a general partnership duly formed and validly existing under the laws of the 
State of Delaware and had all requisite power and authority to own, lease and 
operate its properties and to conduct its business as it was being conducted, 
and (b) duly qualified or licensed to do business and was in good standing in 
each jurisdiction in which the property owned, leased or operated by it or the 
nature of the business conducted by it makes such qualification necessary.  No 
representation is made concerning the conversion of the Company into a limited 
partnership

                    The Company has heretofore delivered to Buyer complete and 
correct copies of the partnership agreement of the Company, as currently in 
effect."

     6.     Section 3.6 of the Purchase Agreement shall be amended by adding 
the following at the end of the current section:

                    "For purposes of this Section 3.6, the parties have 
assumed that, immediately after the Closing, National-Oilwell, L.P. shall be 
the same legal entity as the Company on the date hereof."

     7.     Section 3.14(g)(i) and (ii) of the Purchase Agreement are hereby 
amended and restated in their entirety as follows:





Messrs. Gedeon and Harmer
Page 3
January 15, 1996


                    "(i) involves sales of products of the Company and its 
Subsidiaries, or purchases by the Company and the Subsidiaries of products and 
services, in excess of $500,000, (ii) involves future expenditures in excess 
of $200,000 in any one calendar year, and is not terminable by the Company or 
the Subsidiary of 30 days' or fewer notice without penalty, or"

     8.     The term "Material Contracts" as defined in the Purchase Agreement 
shall not include maintenance and repair operating supply contracts that are 
cancellable by the Company on less than 90 days notice.

     9.     Exhibit C to the Purchase Agreement, labelled "Allocation of 
Purchase Price", shall be deleted in its entirety and replaced by a new 
Exhibit C to the Purchase Agreement in the form attached hereto as Exhibit E.

     10.     The closing of the transactions contemplated by the Purchase 
Agreement shall be effective as of January 1, 1996.

     11.     Effective as of the Closing, the Asset Transfer Agreement dated 
March 31, 1987 between National Supply Company, Inc. and the Company and the 
Asset Transfer Agreement dated March 31, 1987 between Oilwell, Inc. And the 
Company shall terminate.  All representations, warranties, covenants, 
indemnifications and other provisions of the Purchase Agreement shall remain 
in effect and govern the relationship between the parties.

     If this letter correctly sets forth our agreement on the matters set 
forth herein, please execute three copies of this letter in the spaces 
provided below.  One copy should be returned to each of the other two parties; 
the third copy is for your files.

                                      Very truly yours,

                                      NOW HOLDINGS, INC.
