</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under Delaware law, a corporation may include provisions in its certificate of incorporation
that will relieve its directors of monetary liability for breaches of their fiduciary duty to the
corporation, except under certain circumstances, including a breach of the director&#146;s duty of
loyalty, acts or omissions of the director not in good faith or which involve intentional
misconduct or a knowing violation of law, the approval of an improper payment of a dividend or an
improper purchase by the corporation of stock or any transaction from which the director derived an
improper personal benefit. The Company&#146;s Restated Certificate of Incorporation provides that the
Company&#146;s directors are not liable to the Company or its stockholders for monetary damages for
breach of their fiduciary duty, subject to the described exceptions specified by Delaware law.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under Section&nbsp;145 of the Delaware General Corporation Law and the Company&#146;s bylaws, as
restated, the Company is obligated to indemnify its present and former directors and officers and
may indemnify other employees and individuals against expenses (including attorneys&#146; fees),
judgments, fines and amounts paid in settlement in connection with specified actions, suits or
proceedings, whether civil, criminal, administrative or investigative (other than an action by or
in the right of the corporation, a &#147;derivative action&#148;), if the person to whom indemnity is granted
acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the
Company&#146;s best interests, and with respect to any criminal action or proceeding, had no reasonable
cause to believe his or her conduct was unlawful. A similar standard of care is applicable in the
case of derivative actions, except that indemnification extends only to expenses (including
attorneys&#146; fees) incurred in connection with defense or settlement of such an action, and the
Delaware General Corporation Law requires court approval before there can be any indemnification
where the person seeking indemnification has been found liable to the Company.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law also empowers the Company to purchase and
maintain insurance on behalf of any person who is or was an officer or director of the Company
against liability asserted against or incurred by him in any such capacity, whether or not the
Company would have the power to indemnify such officer or director against such liability under the

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to
directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions,
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 1933 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 1933 Act and will be governed by
the final adjudication of such issue.

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
Item 3. Incorporation of Documents by Reference.
The following documents which have been filed with the Securities and Exchange Commission (the
"Commission") by Grant Prideco, Inc., a Delaware corporation (the "Company"), are incorporated
herein by reference and made a part hereof:
(a) The Company's Annual Report on Form 10-K for the year ended December 31, 2006, filed
with the Commission on March 1, 2007; and
(b) The description of the Common Stock contained in the Company's Registration Statement
No. 333-102630, filed with the Commission on January 21, 2003, as amended on February 19, 2003.
All documents filed by the Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the
Securities Exchange Act of 1934 (the "Exchange Act") subsequent to the effective date of this
Registration Statement, prior to the filing of a post-effective amendment to this Registration
Statement indicating that all securities offered hereby have been sold or deregistering all
securities then remaining unsold, shall be deemed to be incorporated by reference herein and to be
a part hereof from the date of filing of such documents. Any statement contained herein or in any
document incorporated or deemed to be incorporated by reference herein shall be deemed to be
modified or superseded for purposes of this Registration Statement to the extent that a statement
contained in any other subsequently filed document which also is or is deemed to be incorporated by
reference herein modifies or supersedes such statement. Any such statement so modified or
superseded shall not be deemed to constitute a part of this Registration Statement, except as so
modified or superseded.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Officers and Directors.
Under Delaware law, a corporation may include provisions in its certificate of incorporation
that will relieve its directors of monetary liability for breaches of their fiduciary duty to the
corporation, except under certain circumstances, including a breach of the director's duty of
loyalty, acts or omissions of the director not in good faith or which involve intentional
misconduct or a knowing violation of law, the approval of an improper payment of a dividend or an
improper purchase by the corporation of stock or any transaction from which the director derived an
improper personal benefit. The Company's Restated Certificate of Incorporation provides that the
Company's directors are not liable to the Company or its stockholders for monetary damages for
breach of their fiduciary duty, subject to the described exceptions specified by Delaware law.
Under Section 145 of the Delaware General Corporation Law and the Company's bylaws, as
restated, the Company is obligated to indemnify its present and former directors and officers and
may indemnify other employees and individuals against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement in connection with specified actions, suits or
proceedings, whether civil, criminal, administrative or investigative (other than an action by or
in the right of the corporation, a "derivative action"), if the person to whom indemnity is granted
acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the
Company's best interests, and with respect to any criminal action or proceeding, had no reasonable
cause to believe his or her conduct was unlawful. A similar standard of care is applicable in the
case of derivative actions, except that indemnification extends only to expenses (including
attorneys' fees) incurred in connection with defense or settlement of such an action, and the
Delaware General Corporation Law requires court approval before there can be any indemnification
where the person seeking indemnification has been found liable to the Company.
2
Table of Contents
Section 145 of the Delaware General Corporation Law also empowers the Company to purchase and
maintain insurance on behalf of any person who is or was an officer or director of the Company
against liability asserted against or incurred by him in any such capacity, whether or not the
Company would have the power to indemnify such officer or director against such liability under the
provisions of Section 145. The Company has purchased and maintains a directors' and officers'
liability policy for such purposes.

Item 9. Undertakings.
The undersigned Registrant hereby undertakes:
4
Table of Contents
(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, as
amended (the "1933 Act");
(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 prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20% change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in the effective registration
statement; and
(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 paragraphs (1)(i) and (1)(ii) do not apply if the information required to
be included in a post-effective amendment by those paragraphs is contained in periodic reports
filed by the Registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the
Registration Statement.
(2) That, for the purpose of determining any liability under the 1933 Act, 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.
The undersigned Registrant hereby undertakes that, for the purposes of determining any
liability under the 1933 Act, each filing of the Registrant's annual report pursuant to Section
13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) 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.
Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to
directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions,
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 1933 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 1933 Act and will be governed by
the final adjudication of such issue.
