Covenants of the Company and Grant Prideco. The Company and Grant Prideco covenant and agree with the Initial Purchasers that: -13- (a) Neither the Company nor Grant Prideco will amend or supplement the Final Memorandum or any amendment or supplement thereto of which the Initial Purchasers shall not previously have been advised and furnished a copy for a reasonable period of time prior to the proposed amendment or supplement and as to which the Initial Purchasers shall not have given their consent. The Company and Grant Prideco will promptly, upon the reasonable request of the Initial Purchasers or counsel for the Initial Purchasers, make any amendments or supplements to the Preliminary Memorandum or the Final Memorandum that may be necessary or advisable in connection with the resale of the Notes by the Initial Purchasers. (b) The Company and Grant Prideco will cooperate with the Initial Purchasers in arranging for the qualification of the Notes for offering and sale under the securities or "Blue Sky" laws of which jurisdictions as the Initial Purchasers may designate and will continue such qualifications in effect for as long as may be necessary to complete the resale of the Notes; provided, however, that in connection therewith, neither the Company nor Grant Prideco shall be required to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction or subject itself to taxation in excess of a nominal dollar amount in any such jurisdiction where it is not then so subject. (c) If, at any time prior to the completion of the distribution by the Initial Purchasers of the Notes or the Private Exchange Notes (if applicable), any event occurs or information becomes known as a result of which the Final Memorandum as then amended or supplemented would include any untrue statement of a material fact, or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if for any other reason it is necessary at any time to amend or supplement the Final Memorandum to comply with applicable law, the Company or Grant Prideco will promptly notify the Initial Purchasers thereof and will prepare, at the expense of the Company and Grant Prideco, an amendment or supplement to the Final Memorandum that corrects such statement or omission or effects such compliance. (d) The Company and Grant Prideco will, without charge, provide to the Initial Purchasers and to counsel for the Initial Purchasers as many copies of the Preliminary Memorandum and the Final Memorandum or any amendment or supplement thereto as the Initial Purchasers may reasonably request. (e) The Company and Grant Prideco will apply the net proceeds from the sale of the Notes as set forth under "Use of Proceeds" in the Final Memorandum. (f) For so long as any of the Notes remain outstanding, the Company and Grant Prideco will furnish to the Initial Purchasers copies of all reports and other communications (financial or otherwise) furnished by the Company or Grant Prideco to the Trustee or to the holders of the Notes and, as soon as available, copies of any reports or financial statements furnished to or filed by the Company or Grant Prideco with the Commission or any national -14- securities exchange on which any class of securities of the Company or Grant Prideco may be listed. (g) Prior to the Closing Date, the Company or Grant Prideco will furnish to the Initial Purchasers at their request, as soon as they have been completed, a copy of any unaudited interim financial statements of Grant Prideco for any period subsequent to the period covered by the most recent financial statements appearing in the Final Memorandum. (h) None of the Company, Grant Prideco or any of their Affiliates will sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any "security" (as defined in the Act) which could be integrated with the sale of the Notes in a manner that would require the registration under the Act of the Notes. (i) None of the Company or Grant Prideco will, and will not permit the Subsidiaries to, engage in any form of general solicitation or general advertising (as those terms are used in Regulation D under the Act) in connection with the offering of the Notes or in any manner involving a public offering within the meaning of Section 4(2) of the Act. (j) For so long as any of the Notes remain outstanding, the Company and Grant Prideco will make available at their expense, upon request, to any holder of such Notes and any prospective purchasers thereof the information specified in Rule 144A(d)(4) under the Act, unless Grant Prideco is then subject to Section 13 or 15(d) of the Exchange Act. (k) The Company and Grant Prideco will use their reasonable best efforts to (i) permit the Notes to be designated PORTAL securities in accordance with the rules and regulations adopted by the NASD relating to trading in the Private Offerings, Resales and Trading through Automated Linkages market (the "Portal Market") and (ii) permit the Notes to be eligible for clearance and settlement through The Depository Trust Company. (l) In connection with Notes offered and sold in an off shore transaction (as defined in Regulation S) the Company and Grant Prideco will not register any transfer of such Notes not made in accordance with the provisions of Regulation S and will not, except in accordance with the provisions of Regulation S, if applicable, issue any such Notes in the form of definitive securities. 6. Expenses. The Company and Grant Prideco agree to pay all costs and expenses incident to the performance of their obligations under this Agreement, whether or not the transactions contemplated herein are consummated or this Agreement is terminated pursuant to Section 11 hereof, including all costs and expenses incident to (i) the printing, word processing or other production of documents with respect to the transactions contemplated hereby, including any costs of printing the Preliminary Memorandum and the Final Memorandum and any amendment or supplement thereto, and any "Blue Sky" memoranda, (ii) all arrangements relating to the delivery to the Initial Purchasers of copies of the foregoing documents, (iii) the fees and disbursements of the counsel, the accountants and any other experts or -15- advisors retained by the Company and Grant Prideco, (iv) preparation (including printing), issuance and delivery to the Initial Purchasers of the Notes, (v) the qualification of the Notes under state securities and "Blue Sky" laws, including filing fees and fees and disbursements of counsel for the Initial Purchasers relating thereto, (vi) expenses in connection with the "roadshow" and any other meetings with prospective investors in the Notes, (vii) fees and expenses of the Trustee including fees and expenses of counsel, (viii) all expenses and listing fees incurred in connection with the application for quotation of the Notes on the PORTAL Market and (ix) any fees charged by investment rating agencies for the rating of the Notes. If the sale of the Notes provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 7 hereof is not satisfied, because this Agreement is terminated or because of any failure, refusal or inability on the part of the Company or Grant Prideco to perform all obligations and satisfy all conditions on their part to be performed or satisfied hereunder (other than solely by reason of a default by the Initial Purchasers of their obligations hereunder after all conditions hereunder have been satisfied in accordance herewith), the Company and Grant Prideco agree to promptly reimburse the Initial Purchasers upon demand for all out-of-pocket expenses (including fees, disbursements and charges of Cahill Gordon & Reindel, counsel for the Initial Purchasers) that shall have been incurred by the Initial Purchasers in connection with the proposed purchase and sale of the Notes. 7.

Terms used in this Section 8 and not defined in this Agreement have the meanings given to them in Regulation S. 9. Indemnification and Contribution. (a) Each of the Company and Grant Prideco agrees to indemnify and hold harmless each Initial Purchaser and each person, if any, who controls any Initial Purchasers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which any Initial Purchasers or such controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement made by the Company or Grant Prideco in Section 2 hereof; (ii) any untrue statement or alleged untrue statement of any material fact contained in any Memorandum or any amendment or supplement thereto; or (iii) the omission or alleged omission to state, in any Memorandum or any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse, as incurred, the Initial Purchasers and each such controlling person for any legal or other expenses incurred by the Initial Purchasers or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, the Company and Grant Prideco 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 any untrue statement or alleged untrue statement or omission or alleged omission made in any Memorandum or any amendment or supplement thereto in reliance upon and in conformity with written information concerning the Initial Purchasers furnished to the Company or Grant Prideco by the Initial Purchasers specifically for -19- use therein. The indemnity provided for in this Section 9 will be in addition to any liability that the Company and Grant Prideco may otherwise have to the indemnified parties. The Company and Grant Prideco shall not be liable under this Section 9 for any settlement of any claim or action effected without Grant Prideco's prior written consent, which shall not be unreasonably withheld. (b) Each Initial Purchasers, severally and not jointly, agrees to indemnify and hold harmless the Company and Grant Prideco, their respective directors, officers and each person, if any, who controls the Company or Grant Prideco within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company, Grant Prideco or any such director, officer or controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Memorandum or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact required to be stated in any Memorandum or any amendment or supplement thereto, 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 written information concerning the Initial Purchasers, furnished to the Company or Grant Prideco by such Initial Purchasers specifically for use therein; and subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses incurred by the Company, Grant Prideco or any such director, officer or controlling person in connection with investigating or defending against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action in respect thereof. The indemnity provided for in this Section 9 will be in addition to any liability that the Initial Purchasers may otherwise have to the indemnified parties. The Initial Purchasers shall not be liable under this Section 9 for any settlement of any claim or action effected without their consent, which shall not be unreasonably withheld. The Company and Grant Prideco shall not, without the prior written consent of the Initial Purchasers, effect any settlement or compromise of any pending or threatened proceeding in respect of which the Initial Purchasers are or could have been a party, or indemnity could have been sought hereunder by any Initial Purchaser, unless such settlement (A) includes an unconditional written release of the Initial Purchasers, in form and substance reasonably satisfactory to the Initial Purchasers, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any Initial Purchaser. (c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 9, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the -20- extent such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after receipt by the indemnifying party of notice of the institution of such action, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Initial Purchasers in the case of paragraph (a) of this Section 9 or the Company and Grant Prideco in the case of paragraph (b) of this Section 9, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions) or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. All fees and expenses reimbursed pursuant to this paragraph (c) shall be reimbursed as they are incurred. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnified party waived in writing its rights under this Section 9, in which case the indemnified party may effect such a settlement without such consent. (d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 9 is unavailable to, or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect -21- thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Notes or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Company and Grant Prideco on the one hand and any Initial Purchaser on the other shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses) received by the Company and Grant Prideco bear to the total discounts and commissions received by such Initial Purchaser. The relative fault of the parties 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 and Grant Prideco on the one hand, or such Initial Purchaser on the other, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The Company, Grant Prideco and the Initial Purchasers agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Initial Purchaser shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact, and 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. For purposes of this paragraph (d), each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each director of the Company and Grant Prideco, each officer of the Company and Grant Prideco and each person, if any, who controls the Company or Grant Prideco within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company and Grant Prideco. 10. Survival Clause. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Company, Grant Prideco, their officers and the Initial Purchasers set forth in this Agreement or made by or on behalf of them pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Company, Grant Prideco, any of their officers or directors, the Initial Purchasers or any controlling person referred to in Section 9 hereof and (ii) delivery of and -22- payment for the Notes. The respective agreements, covenants, indemnities and other statements set forth in Sections 6, 9, 10 and 15 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement. 11.
