In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any.

The term "MAKE-WHOLE AMOUNT" means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings: "CALLED PRINCIPAL" means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 8.2 or Section 8.3 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. "DISCOUNTED VALUE" means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. "REINVESTMENT YIELD" means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as "Page 678" on the Dow Jones Markets Service (or such other display as may replace Page 678 on the Dow Jones Markets Service) for actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or HYDRIL COMPANY 20 NOTE PURCHASE AGREEMENT 26 (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable, the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for activity traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the actively traded U.S. Treasury security with the duration closest to and greater than the Remaining Average Life and (2) the actively traded U.S. Treasury security with the duration closest to and less than the Remaining Average Life. "REMAINING AVERAGE LIFE" means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. "REMAINING SCHEDULED PAYMENTS" means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the term of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2, Section 8.3 or 12.1. "SETTLEMENT DATE" means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or Section 8.3 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

The Company and the holders of the Notes hereby acknowledge and agree that if the Company shall enter into any amendment to the Bank Agreement that provides for the benefit of the lenders thereunder any Financial Covenants that are relatively more favorable to such lenders than the Financial Covenants that are currently in effect pursuant to the Bank Agreement as compared to the Financial Covenants set forth in this Agreement, then, and in each and any such event, the Financial Covenants in this Agreement shall be and shall be deemed to be, notwithstanding the provisions of Section 17 and without any further action on the part of the Company or any other Person being necessary or required, amended to afford the holders of Notes the same benefits and rights as such amendment to, or other agreements in respect of, the Financial Covenants of the Bank Agreement afforded to such lenders; provided, however, that if any such amendment shall be modified or terminated, then the deemed amendment to this Agreement effected by this Section 9.7 shall be deemed to have been simultaneously modified (if any such modification of the Bank Agreement amendment would itself require a deemed amendment pursuant to this Section 9.7) or terminated (if such Bank Agreement amendment has HYDRIL COMPANY 23 NOTE PURCHASE AGREEMENT 29 been terminated or if such modification of the Bank Agreement amendment would not itself require a deemed amendment pursuant to this Section 9.7). (If such deemed amendment shall be deemed to have been terminated, the relevant Financial Covenant or Financial Covenants herein shall be deemed to provide as it or they would have if such deemed amendment had never come into effect).

Any such determination of Consolidated EBITDA and Consolidated Fixed Charges shall be made in good faith and on a reasonable basis by a Responsible Officer. For the purposes of this Section 10.1 and Section 10.2, any Person becoming a Subsidiary after the date hereof shall be deemed, at the time it becomes a Subsidiary, to have incurred all of its then outstanding Debt, and any Person extending, renewing or refunding any Debt shall be deemed to have incurred such Debt at the time of such extension, renewal or refunding. 10.2 SUBSIDIARY DEBT.

Such violation of this Section 10.4 will constitute an Event of Default, whether or not provision is made for an equal and ratable Lien pursuant to this Section 10.4.

(a) PROHIBITED AND PERMITTED TRANSFERS. The Company will not, and will not permit any Subsidiary to, sell, lease as lessor, transfer or otherwise dispose of any Property (including, without limitation, (x) any sale, lease, transfer or other disposition of Capital Stock of any Subsidiary and (y) any transfer of Capital Stock of any Subsidiary or Property of any Subsidiary, in either case, by means of a merger or consolidation of such Subsidiary, except as permitted with respect to the Company under Section 10.6) (herein referred to, collectively, as "TRANSFERS"), except: (i) Transfers of inventory and other assets for cash (or cash equivalents) equal to the Fair Market Value of such inventory or other assets, in each case in the ordinary course of business of the Person making such Transfer; (ii) Transfers consisting of a swap of Property of the Company or a Subsidiary for Property of another Person that (x) will be used and useful in the business of the Company or such Subsidiary and (y) has a Fair Market Value substantially the same as the Property Transferred by the Company or such Subsidiary, so long as such swap is customary in the industry in which the Company or such Subsidiary operates and is consummated on customary terms and conditions; (iii) Transfers from a Subsidiary to the Company or a Wholly-Owned Subsidiary; (iv) Transfers from the Company to a Wholly-Owned Subsidiary; (v) the issuance of directors' qualifying shares or, in the case of a Person organized under the laws of a jurisdiction outside the United States, the issuance of equity to local residents to the extent required by local law ("REQUIRED LOCAL EQUITY"); and (vi) a Transfer (other than as specified in the foregoing clauses (i) to (v), inclusive) of Property in exchange for the Fair Market Value thereof, provided that, immediately after giving effect thereto, (A) no Event of Default would exist, and HYDRIL COMPANY 31 NOTE PURCHASE AGREEMENT 37 (B) the aggregate net book value of all Transfers consummated under this Section 10.7(a)(vi) (such net book value being determined immediately after the consummation of each such Transfer) during the then current fiscal year of the Company would not exceed 15% of Consolidated Total Capitalization determined as of the last day of the then most recently ended fiscal year of the Company; provided, that if the requirements set forth in the foregoing clause (B) shall not be satisfied immediately after consummation of such Transfer, the Company shall be deemed to be in compliance with such clause (B) on a provisional basis, with respect to such Transfer (a "PROVISIONAL QUALIFIED TRANSFER"), for a period of 365 days following such consummation, so long as such Transfer was in exchange for cash (or cash equivalents). If all Net Proceeds arising from any Provisional Qualified Transfer (x) shall be invested by the Company and the Subsidiaries in Operating Assets at any time during such 365 day period or (y) shall be applied to the prepayment of the principal of any Senior Funded Debt during such period, then the Company shall be deemed to have complied with this Section 10.7(a) with respect to such Provisional Qualified Transfer.

(b) If any other Event of Default has occurred and is continuing, any holder or holders of more than 25% in principal amount of the Notes at the time outstanding may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable. (c) If any Event of Default described in clause (a) or (b) of Section 11 has occurred and is continuing, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable. Upon any Notes becoming due and payable under this Section 12.1, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon and (y) the Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances. 12.2 OTHER REMEDIES. If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. 12.3 RESCISSION. At any time after any Notes have been declared due and payable pursuant to clause (b) or clause (c) of Section 12.1, the holders of not less than 76% in principal amount of the Notes then outstanding, by written notice to the Company, may rescind and annul any such declaration and its consequences if HYDRIL COMPANY 37 NOTE PURCHASE AGREEMENT 43 (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, due and payable on any Notes other than by reason of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and (c) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes.

No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder's rights, powers or remedies. No right, power or remedy conferred by any Financing Document upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys' fees, expenses and disbursements. 13.

Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1.

HYDRIL COMPANY 41 NOTE PURCHASE AGREEMENT 47 17.3 BINDING EFFECT, ETC. Any amendment or waiver consented to as provided in this Section 17 applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Note nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any holder of such Note.

Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under any Financing Document, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding. 18.

Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 20. 21.

The Company and each holder of Notes specifically intend and agree to limit contractually the amount of interest payable under this Agreement and the Notes, and all other instruments and agreements related hereto and thereto, to the maximum amount of interest lawfully permitted to be charged under applicable law. If applicable law is ever construed so as to render usurious any amounts called for under this Agreement, the Notes or any related document, or contracted for, charged, taken, reserved or received with respect to the extension of credit evidenced hereby and thereby, or if acceleration of maturity of any of the Notes or if any prepayment by the Company results in the Company having paid, or demand having been made on the Company to pay, any interest in excess of that permitted by applicable law, then all excess amounts theretofore received by the holder or holders of the Notes shall be credited on the principal balances of the Notes (or, if the Notes have been or would thereby be repaid in full, refunded to the Company), and the provisions of this Agreement, the Notes and any related document or demand on the Company shall immediately be deemed reformed and the amounts thereafter collectible hereunder and thereunder shall immediately be reduced, without the necessity of the execution of any new documents, so as to comply with applicable law, but so as to permit the recovery of the fullest amounts otherwise called for hereunder and thereunder.
