<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;National Oilwell Varco, Inc. (the &#147;Company&#148;) is filing this Registration Statement on Form S-8
(the &#147;Registration Statement&#148;) relating to its common stock, par value $0.01 per share (the &#147;Common
Stock&#148;), that may be offered and sold pursuant to the Grant Prideco, Inc. 2000 Employee Stock
Option and Restricted Stock Plan; the Grant Prideco, Inc. 2000 Non-Employee Director Stock Option
Plan; the Grant Prideco, Inc. 2001 Stock Option and Restricted Stock Plan; and the Grant Prideco,
Inc. 2006 Long-Term Incentive Plan (collectively, the &#147;Plans&#148;).
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On April&nbsp;21, 2008, pursuant to an Agreement and Plan of Merger (the &#147;Merger Agreement&#148;) dated
as of December&nbsp;16, 2007 by and among the Company, NOV Sub, Inc., a Delaware corporation and a
wholly owned subsidiary of the Company (&#147;NOV Sub&#148;), and Grant Prideco, Inc., a Delaware corporation
(&#147;Grant Prideco&#148;), among other things, Grant Prideco was merged with and into NOV Sub (the
&#147;Merger&#148;), with NOV Sub as the surviving entity, and each outstanding share of common stock, par
value $0.01, of Grant Prideco (&#147;Grant Prideco Common Stock&#148;) was converted into the right to
receive 0.4498 of a share of Common Stock and $23.20 in cash. At the effective time of the Merger,
each outstanding option to acquire shares of Grant Prideco Common Stock, whether vested or
unvested, was assumed by the Company and converted into an option to purchase shares of Common
Stock, based on the terms of the Merger Agreement and after applying an exchange ratio with respect
to both the number of shares issuable under the options and the related exercise price therefore.
Such assumed options included options granted by Grant Prideco under the Plans and under a
Distribution Agreement dated March&nbsp;22, 2000 between Grant Prideco and Weatherford International,
Inc., a Delaware corporation (&#147;Weatherford Delaware&#148;).
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In connection with the Merger Agreement, the Company entered into the Weatherford Employee
Benefit Agreement dated as of April&nbsp;21, 2008 with Weatherford International Ltd., a Bermuda
exempted company (&#147;Weatherford Bermuda&#148;), Weatherford Delaware (together with Weatherford Bermuda
and its subsidiaries, collectively, the &#147;Weatherford Parties&#148;), on behalf of itself and its
subsidiaries, and Grant Prideco, whereby the Company agreed to assume certain obligations of Grant
Prideco to issue shares of common stock to participants and former participants of three employee
benefit plans of the Weatherford Parties upon the occurrence of events that cause benefits to
become distributable under such plans. Such benefit plans are the Weatherford International, Inc.
Executive Deferred Compensation Stock Ownership Plan, the Weatherford International, Inc. Foreign
Executive Deferred Compensation Plan and the Weatherford International, Inc. Executive Deferred
Compensation Plan for Non-Employee Directors.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Except to the extent indicated below, there is no charter provision, bylaw, contract,
arrangement or statute under which any director or officer of National Oilwell Varco is insured or
indemnified in any manner against any liability that he or she may incur in his or her capacity as
such.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law (the &#147;DGCL&#148;) authorizes, inter alia, a
corporation to indemnify any person who was or is a party or is threatened to be made a party to
any threatened, pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by

officer or director of such corporation, or is or was serving at the request of such corporation as
a director, officer, employee or agent of another corporation, partnership, joint venture, trust or
other enterprise. The indemnity may include expenses (including attorney&#146;s fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, provided that he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. A
Delaware corporation may indemnify past or present officers and directors of such corporation or of
another corporation or other enterprise at the former corporation&#146;s request, in an action by or in
the right of the corporation to procure a judgment in its favor under the same conditions, except
that no indemnification is permitted without judicial approval if such person is adjudged to be
liable to the corporation. Where an officer or director is successful on the merits or otherwise in
defense of any action referred to above, or in defense of any claim, issue or matter therein, the
corporation must indemnify him against the expenses (including attorney&#146;s fees) which he actually
and reasonably incurred in connection therewith.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 further provides that any indemnification shall be made by the corporation only as
authorized in each specific case upon a determination by the (i)&nbsp;stockholders, (ii)&nbsp;board of
directors by a majority vote or a quorum consisting of directors who were not parties to such
action, suit or proceeding or (iii)&nbsp;independent counsel if a quorum of disinterested directors so
directs. Section&nbsp;145 provides that indemnification pursuant to its provisions is not exclusive of
other rights of indemnification to which a person may be entitled under any bylaw, agreement, vote
of stockholders or disinterested directors or otherwise. Section&nbsp;145 of the DGCL also empowers
National Oilwell Varco to purchase and maintain insurance on behalf of any person who is or was an
officer or director of National Oilwell Varco against liability asserted against or incurred by him
in any such capacity, whether or not National Oilwell Varco would have the power to indemnify such
officer or director against such liability under the provisions of Section&nbsp;145. National Oilwell
Varco maintains a liability policy for directors and officers for such purposes.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;Sixth, Part&nbsp;II, Section&nbsp;1 of National Oilwell Varco&#146;s Amended and Restated Certificate
of Incorporation and Article&nbsp;VI of National Oilwell Varco&#146;s Amended and Restated Bylaws each
provide that directors and officers shall be indemnified, and employees and agents may be
indemnified, to the fullest extent permitted by Section&nbsp;145 of the DGCL.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The merger agreement, dated as of December&nbsp;16, 2007, between National Oilwell Varco, Inc., NOV
Sub, Inc. and Grant Prideco, Inc. provides that for six years after the effective time of the
merger contemplated by that agreement, National Oilwell Varco will indemnify and hold harmless each
person who was a director or officer of Grant Prideco, Inc. prior to the effective time of that
merger from their acts or omissions in those capacities occurring prior to the effective time of
that merger to the fullest extent permitted by applicable law.

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

as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such

receive 0.4498 of a share of Common Stock and $23.20 in cash. At the effective time of the Merger,
each outstanding option to acquire shares of Grant Prideco Common Stock, whether vested or
unvested, was assumed by the Company and converted into an option to purchase shares of Common
Stock, based on the terms of the Merger Agreement and after applying an exchange ratio with respect
to both the number of shares issuable under the options and the related exercise price therefore.
Such assumed options included options granted by Grant Prideco under the Plans and under a
Distribution Agreement dated March 22, 2000 between Grant Prideco and Weatherford International,
Inc., a Delaware corporation ("Weatherford Delaware").
In connection with the Merger Agreement, the Company entered into the Weatherford Employee
Benefit Agreement dated as of April 21, 2008 with Weatherford International Ltd., a Bermuda
exempted company ("Weatherford Bermuda"), Weatherford Delaware (together with Weatherford Bermuda
and its subsidiaries, collectively, the "Weatherford Parties"), on behalf of itself and its
subsidiaries, and Grant Prideco, whereby the Company agreed to assume certain obligations of Grant
Prideco to issue shares of common stock to participants and former participants of three employee
benefit plans of the Weatherford Parties upon the occurrence of events that cause benefits to
become distributable under such plans. Such benefit plans are the Weatherford International, Inc.
Executive Deferred Compensation Stock Ownership Plan, the Weatherford International, Inc. Foreign
Executive Deferred Compensation Plan and the Weatherford International, Inc. Executive Deferred
Compensation Plan for Non-Employee Directors.

"Exchange Act").
Each document filed with the Commission by the Company pursuant to Sections 13(a), 13(c), 14

or superseded shall not be deemed, except as so modified or superseded, to constitute a part of

Item 4.
Description of Securities.
Not Applicable.
Item 5.
Interests of Named Experts and Counsel.
Not Applicable.
Item 6.
Indemnification of Directors and Officers.
Except to the extent indicated below, there is no charter provision, bylaw, contract,
arrangement or statute under which any director or officer of National Oilwell Varco is insured or
indemnified in any manner against any liability that he or she may incur in his or her capacity as
such.
Section 145 of the Delaware General Corporation Law (the "DGCL") authorizes, inter alia, a
corporation to indemnify any person who was or is a party or is threatened to be made a party to
any threatened, pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by
II-1
or in the right of the corporation), by reason of the fact that such person is or was an
officer or director of such corporation, or is or was serving at the request of such corporation as
a director, officer, employee or agent of another corporation, partnership, joint venture, trust or
other enterprise. The indemnity may include expenses (including attorney's fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, provided that he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. A
Delaware corporation may indemnify past or present officers and directors of such corporation or of
another corporation or other enterprise at the former corporation's request, in an action by or in
the right of the corporation to procure a judgment in its favor under the same conditions, except
that no indemnification is permitted without judicial approval if such person is adjudged to be
liable to the corporation. Where an officer or director is successful on the merits or otherwise in
defense of any action referred to above, or in defense of any claim, issue or matter therein, the
corporation must indemnify him against the expenses (including attorney's fees) which he actually
and reasonably incurred in connection therewith.
Section 145 further provides that any indemnification shall be made by the corporation only as
authorized in each specific case upon a determination by the (i) stockholders, (ii) board of
directors by a majority vote or a quorum consisting of directors who were not parties to such
action, suit or proceeding or (iii) independent counsel if a quorum of disinterested directors so
directs. Section 145 provides that indemnification pursuant to its provisions is not exclusive of
other rights of indemnification to which a person may be entitled under any bylaw, agreement, vote
of stockholders or disinterested directors or otherwise. Section 145 of the DGCL also empowers
National Oilwell Varco to purchase and maintain insurance on behalf of any person who is or was an
officer or director of National Oilwell Varco against liability asserted against or incurred by him
in any such capacity, whether or not National Oilwell Varco would have the power to indemnify such
officer or director against such liability under the provisions of Section 145. National Oilwell
Varco maintains a liability policy for directors and officers for such purposes.
Article Sixth, Part II, Section 1 of National Oilwell Varco's Amended and Restated Certificate
of Incorporation and Article VI of National Oilwell Varco's Amended and Restated Bylaws each
provide that directors and officers shall be indemnified, and employees and agents may be
indemnified, to the fullest extent permitted by Section 145 of the DGCL.
The merger agreement, dated as of December 16, 2007, between National Oilwell Varco, Inc., NOV
Sub, Inc. and Grant Prideco, Inc. provides that for six years after the effective time of the
merger contemplated by that agreement, National Oilwell Varco will indemnify and hold harmless each
person who was a director or officer of Grant Prideco, Inc. prior to the effective time of that
merger from their acts or omissions in those capacities occurring prior to the effective time of
that merger to the fullest extent permitted by applicable law.

Item 9.
Undertakings.
(a) The undersigned registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:
(i) To include any prospectus required by section 10(a)(3) of the Securities Act of
1933;
(ii) To reflect in the prospectus any facts or events arising after the effective date
of the registration statement (or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change in the information set
forth in the registration statement. Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of a prospectus filed with the
Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price
represent no more than a 20% change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration statement;
(iii) To include any material information with respect to the plan of distribution not
previously disclosed in the registration statement or any material change to such
information in the registration statement; provided, however, that the undertakings set
forth in paragraphs (i) and (ii) above do not apply if the registration statement is on Form
S-8, and the information required to be included in a post-effective amendment by those
paragraphs is contained in reports filed with or furnished to the Commission by the
II-3
registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933,
each such post-effective amendment 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.
(3) To remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the offering.
(b) The 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 this 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.
(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the registrant pursuant to the
provisions described under Item 6 above, or otherwise, the registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 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 Securities Act of 1933 and will be governed by the final adjudication of such
issue.
