               (i) No Debtor shall initiate any action to remedy such Event of Default without granting Administrative Agent advance written notice of such Debtor’s intent to initiate such actions and the opportunity to consult with such Debtor regarding such Debtor’s proposed actions (unless immediate action is necessary to prevent loss to such Debtor);

               (ii) At Administrative Agent’s request, each Debtor shall take any actions reasonably requested by Administrative Agent with respect to such Event of Default, including diligently endeavoring to cure any material defect existing or claimed, and taking all reasonably necessary and desirable steps for the defense of any legal proceedings, including the employment of counsel, the prosecution or defense of litigation, and the release or discharge of all adverse claims;

The amount and nature of any expense of Administrative Agent hereunder shall be conclusively established by a certificate of any officer of Administrative Agent absent manifest error.

          (f) Debtor irrevocably appoints Administrative Agent as Debtor’s attorney in fact, with full authority to act during the existence of an Event of Default for Debtor and in the name of Debtor, to take any action and execute any agreement which Administrative Agent deems necessary or advisable to accomplish the purposes of this Agreement, including the matters that Administrative Agent is expressly authorized to take pursuant to this Agreement (including the matters described in paragraph (c) above), and instituting proceedings Administrative Agent deems necessary or desirable to enforce the rights of Administrative Agent with respect to this Agreement.

     4.6 Investment Property. With respect to Investment Property and Pledged Securities:

          (a) If any Debtor shall at any time hold or acquire any Pledged Securities which are certificated securities, whether as a stock split, stock dividend, or other distribution with respect to Pledged Securities, or otherwise, such Debtor shall promptly, and in any event within ten (10) Business Days after receipt thereof, deliver the same to the Administrative Agent, accompanied by such instruments of transfer or assignment duly executed in blank as the Administrative Agent may from time to time specify. If any Pledged Securities now owned or hereafter acquired by any Debtor are uncertificated securities and are issued to such Debtor or its

-13-

nominee directly by the issuer thereof, such Debtor shall immediately notify the Administrative Agent thereof, and shall take any actions requested by the Administrative Agent to enable the Administrative Agent to obtain “control” (within the meaning of Section 8-106 of the UCC) with respect thereto. If any Pledged Securities, whether certificated securities or uncertificated securities, or other Investment Property now or hereafter acquired by any Debtor are held or acquired by such Debtor or its nominee through a securities intermediary or commodity intermediary, such Debtor shall immediately notify the Administrative Agent thereof and, shall take any actions requested by the Administrative Agent to enable the Administrative Agent to obtain “control” (within the meaning of Section 8-106 and/or Section 9-106 of the UCC, as applicable) with respect thereto. To the extent that the Administrative Agent has the right pursuant to the foregoing to give entitlement orders or instructions or directions to any issuer, securities intermediary or commodity intermediary or to withhold its consent to the exercise of any withdrawal or dealing rights by any Debtor, the Administrative Agent agrees with each Debtor that the Administrative Agent shall not give any such entitlement orders or instructions or directions to any such issuer, securities intermediary or commodity intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing rights by any Debtor, unless an Event of Default has occurred and is continuing.

          (b) So long as no Event of Default has occurred and is continuing, each Debtor shall be entitled:

               (i) to exercise, in a manner not inconsistent with the terms hereof, the voting power with respect to the Pledged Securities of such Debtor, and for that purpose the Administrative Agent shall (if any Pledged Securities shall be registered in the name of the Administrative Agent or its nominee) execute or cause to be executed from time to time, at the expense of the Parent, such proxies or other instruments in favor of such Debtor or its nominee, in such form and for such purposes as shall be reasonably requested by such Debtor, to enable it to exercise such voting power with respect to the Pledged Securities; and

               (ii) except as otherwise provided herein or in the Credit Agreement, to receive and retain for its own account any and all payments, proceeds, dividends, distributions, property, assets, or rights to the extent such are permitted pursuant to the terms of the Credit Agreement, other than (x) stock or liquidating dividends or (y) other dividends or other amounts payable under or in connection with any recapitalization, restructuring, or other non-ordinary course event (the dividends and amounts in this clause (y) being “Extraordinary Payments”), paid, issued, or distributed from time to time in respect of the Pledged Securities. If any Extraordinary Payment is paid or payable, then such sum shall be paid by each such Debtor to the Administrative Agent promptly, and in any event within ten (10) Business Days after receipt thereof, to be held by the Administrative Agent as additional collateral hereunder.

          (c) Upon the occurrence and during the continuance of any Event of Default, all rights of each Debtor to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 4.6(b) and to receive the payments, proceeds, dividends, distributions, property, assets, or rights that the Debtor would otherwise be authorized to receive and retain pursuant to Section 4.6(b) shall cease, and

-14-

thereupon the Administrative Agent shall be entitled to exercise all voting power with respect to the Pledged Securities and to receive and retain, as additional collateral hereunder, any and all payments, proceeds, dividends, distributions, property, assets, or rights at any time declared or paid upon any of the Pledged Securities during such an Event of Default and otherwise to act with respect to the Pledged Securities as outright owner thereof.

          (d) All payments, proceeds, dividends, distributions, property, assets, instruments or rights that are received by each Debtor contrary to the provisions of this Section 4.6 shall be received and held in trust for the benefit of the Administrative Agent, shall be segregated by each Debtor from other funds of such Debtor and shall be forthwith paid over to the Administrative Agent as Pledged Securities in the same form as so received (with any necessary endorsement).

          (e) If such Debtor is an issuer of Pledged Securities, such Debtor agrees that (i) it will be bound by the terms of this Agreement relating to the Pledged Securities issued by it and will comply with such terms insofar as such terms are applicable to it and (ii) it will comply with instructions received by it pursuant to the terms of Section 4.6(f) with respect to the Pledged Securities issued by it. In addition, if any such Debtor is a partnership or a limited liability company, such Debtor (i) confirms that none of the terms of any equity interest issued by it provides that such equity interest is a “security” within the meaning of the UCC, (ii) agrees that it will take no action to cause or permit any such equity interest to become a security, (iii) agrees that it will not issue any certificate representing any such equity interest and (iv) agrees that if, notwithstanding the foregoing, any such equity interest shall be or become a security, such Debtor will (and the Debtor that holds such equity interest hereby instructs such issuing Debtor to) comply with instructions originated by the Administrative Agent without further consent by such Debtor.

          (f) Each Debtor hereby authorizes and instructs each issuer of any Pledged Securities pledged by such Debtor hereunder to (i) comply with any instruction received by it from the Administrative Agent in writing that (x) states that an Event of Default has occurred and is continuing and (y) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from such Debtor, and each Debtor agrees that each such issuer shall be fully protected in so complying, and (ii) unless otherwise expressly permitted hereby, pay any dividends or other payments with respect to the Pledged Securities directly to the Administrative Agent.

     4.7 Deposit Accounts. For each Deposit Account which is Collateral, the Debtor maintaining such Deposit Account will, to the extent required by Section 5, take any actions requested by the Administrative Agent to enable the Administrative Agent to obtain “control” (within the meaning of Section 9-104 of the UCC) with respect thereto. The Administrative Agent agrees with each Debtor that the Administrative Agent will not give any instructions to a depositary bank directing the disposition of funds from time to time credited to any Deposit Account or withhold any withdrawal rights from any Debtor, unless an Event of Default has occurred and is continuing.

     4.8 Modifications of Receivables, Chattel Paper, Instruments and Payment Intangibles. No Debtor will, without the Administrative Agent’s prior written consent (which

-15-

consent shall not be unreasonably withheld or delayed): (a) compromise or grant any extension of the time of payment of any of the Collateral consisting of Receivables, Chattel Paper, Instruments or payment intangibles, (b) settle the same for less than the full amount thereof, (c) release, wholly or partly, any obligor liable for the payment thereof, or (d) allow any credit or discount whatsoever thereon; provided, that so long as no Event of Default has occurred and is continuing, this Section 4.8 shall not restrict any extensions, credits, discounts, compromises or settlements granted or made by any Debtor in the ordinary course of such Debtor’s business and consistent with such prudent practices used in industries that are the same as or similar to those which such Debtor is engaged.

     4.9 Intellectual Property. With respect to Intellectual Property:

          (a) Such Debtor will (i) continue to use each Trademark necessary to the conduct of its business on each and every trademark class of goods applicable to its current line as reflected in its current catalogs, brochures, and price lists in order to maintain such Trademark in full force free from any claim of abandonment for non-use, (ii) maintain as in the past substantially the same quality of products and services offered under such Trademark, (iii) use such Trademark with the appropriate notice of registration and substantially all other notices and legends required by applicable laws, (iv) not knowingly adopt or use any ▇▇▇▇ which is confusingly similar or a colorable imitation of such Trademark unless the Administrative Agent, for the ratable benefit of the holders of the Secured Obligations, shall obtain a perfected security interest in such ▇▇▇▇ pursuant to this Agreement, and (v) not (and not knowingly permit any licensee or sublicensee thereof to) do any act or knowingly omit to do any act whereby such Trademark may become invalidated or materially impaired in any way;

          (b) Such Debtor will not do any act, or knowingly omit to do any act, whereby any Patent necessary for the conduct of its business could reasonably be expected to become forfeited, abandoned, or dedicated to the public, except where such Debtor has reasonably determined that such Patent is no longer used in the Debtor’s business or no longer of any substantial value;

          (c) Such Debtor (i) will employ each Copyright necessary for the conduct of its business and (ii) will not (and will not knowingly permit any licensee or sublicensee thereof to) do any act or knowingly omit to do any act whereby any material portion of such Copyrights may become invalidated or otherwise impaired, except where such Debtor has reasonably determined that such Copyrights are no longer used in the Debtor’s business or no longer of any substantial value. Such Debtor will not (either itself or through licensees) do any act or knowingly omit to do any act whereby any material portion of such Copyrights may fall into the public domain, except where such Debtor has reasonably determined that such Copyrights are no longer used in the Debtor’s business or no longer of any substantial value;

          (d) Such Debtor will not knowingly use any Intellectual Property necessary for the conduct of its business in a manner that infringes the intellectual property rights of any other Person;

          (e) Such Debtor will notify the Administrative Agent promptly if it knows or has been notified that any application or registration relating to any Intellectual Property

-16-

necessary for the conduct of its business may become forfeited, abandoned, or dedicated to the public, or of any adverse determination or development (including, without limitation, the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office) regarding such Debtor’s ownership of, or the validity of, any such Intellectual Property or such Debtor’s right to register the same or to own and maintain the same;

          (f) Whenever such Debtor, either by itself or through any agent, employee, licensee or designee, shall file an application for the registration of any Intellectual Property necessary for the conduct of its business with the United States Patent and Trademark Office or the United States Copyright Office, such Debtor shall report such filing to the Administrative Agent within 30 days after the date on which such filing occurs. Upon request of the Administrative Agent, such Debtor shall promptly execute and deliver, and have recorded, any and all agreements, instruments, documents, and papers as the Administrative Agent may request to evidence the security interest granted hereunder to the Administrative Agent for the benefit of the holders of the Secured Obligations in any Copyright, Patent, or Trademark necessary for the conduct of its business and the goodwill and general intangibles of such Debtor relating thereto or represented thereby;

          (g) Such Debtor will take all reasonable and necessary steps, including, without limitation, in any proceeding before the United States Patent and Trademark Office, the United States Copyright Office, to maintain and pursue each application relating to any Intellectual Property necessary for the conduct of its business (and to obtain the relevant registration) and to maintain each registration of such material Intellectual Property, including, without limitation, filing of applications for renewal, affidavits of use and affidavits of incontestability;

          (h) In the event that any Intellectual Property necessary for the conduct of its business is infringed, misappropriated or diluted by a third party, such Debtor shall (i) take such actions as such Debtor shall reasonably deem appropriate under the circumstances to protect such Intellectual Property and (ii) if such Intellectual Property is of material economic value, promptly notify the Administrative Agent after it learns thereof and take such actions as such Debtor shall reasonably deem appropriate under the circumstances, including filing suit for infringement, misappropriation or dilution, to seek injunctive relief where appropriate and to recover any and all damages for infringement, misappropriation or dilution; and

          (i) In no event does any provision hereof require a Debtor to perfect security interests in Intellectual Property by filing outside the United States of America.

     4.10 Collateral in the Possession of Bailees, Landlords.

          (a) Each Debtor shall use all commercially reasonable efforts to obtain a Lien Waiver from each landlord, bailee, or other non-Debtor that has possession of any Collateral, or on whose property any Collateral is located, to the extent such Lien Waivers are necessary to ensure that (i) the aggregate fair market value of all Collateral located at any such location that is not subject to a Lien Waiver, or in the possession of any such Person that has not executed a Lien Waiver, does not exceed $1,500,000 (determined on a mathematical average basis for the months

-17-

during the most recently ended quarter) and (ii) the aggregate fair market value of all Collateral located at all such locations that are not subject to Lien Waivers, and in the possession all such Persons that have not executed Lien Waivers, does not exceed $75,000,000 (determined on a mathematical average basis for the months during the most recently ended quarter). Notwithstanding the foregoing, to the extent such Debtor is unable to promptly obtain a Lien Waiver from any such landlord, bailee, or other non-Debtor, then, at the request of the Administrative Agent, such Debtor shall promptly move such Collateral to a location with respect to which the landlord, bailee, or other non-Debtor shall execute a Lien Waiver.

          (a) The Administrative Agent shall have the right, after the occurrence and during the continuation of an Event of Default, to sell any or all of the Pledged Securities in accordance with the terms of this Agreement. If the Administrative Agent shall determine to exercise the right to sell any or all of the Pledged Securities pursuant to this Section 6.4, and if in the opinion of the Administrative Agent it is necessary or advisable to have the Pledged Securities, or that portion thereof to be sold, registered under the provisions of the Securities Act of 1933 (the “Securities Act”), as amended, the relevant Debtor will cause the issuer thereof to execute and deliver, and cause the directors and officers of such issuer to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the opinion of the Administrative Agent, necessary or advisable to register the Pledged Securities, or that portion thereof to be sold, under the provisions of the Securities Act, use its best efforts to cause the registration statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of the Pledged Securities, or that portion thereof to be sold, and make all amendments thereto and/or to the related prospectus which, in the opinion of the Administrative Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. Each Debtor agrees to cause such issuer to comply with the provisions of the securities or “Blue Sky” laws of any and all jurisdictions which the Administrative Agent shall designate and to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act.

          (b) Each Debtor recognizes that the Administrative Agent may be unable to effect a public sale of any or all the Pledged Securities, by reason of certain prohibitions

-22-

contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Debtor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Administrative Agent shall be under no obligation to delay a sale of any of the Pledged Securities for the period of time necessary to permit the issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such issuer would agree to do so.

          (c) Each Debtor agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Securities pursuant to this Section 6.4 valid and binding and in compliance with any and all other applicable laws. Each Debtor further agrees that a breach of any of the covenants contained in this Section 6.4 will cause irreparable injury to the Administrative Agent and the holders of the Secured Obligations, that the Administrative Agent and the holders of the Secured Obligations have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 6.4 shall be specifically enforceable against such Debtor, and such Debtor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred.

     6.5 Foreclosure.

          (a) The Administrative Agent may foreclose on the Collateral in any manner permitted by the courts of or in the State of New York or the jurisdiction in which any Collateral is located. If the Administrative Agent should institute a suit for the collection of the Secured Obligations and for the foreclosure of this Agreement, the Administrative Agent may at any time before the entry of a final judgment dismiss the same, and take any other action permitted by this Agreement.

          (b) To the extent permitted by law, the Administrative Agent may exercise all the foreclosure rights and remedies of an Administrative Agent under the UCC. In connection therewith, the Administrative Agent may sell any Collateral at public or private sale, at the office of the Administrative Agent or elsewhere, for cash or credit and upon such other terms as the Administrative Agent deems commercially reasonable. The Administrative Agent may sell any Collateral at one or more sales, and the security interest granted hereunder shall remain in effect as to the unsold portion of the Collateral. Each Debtor agrees that to the extent permitted by law such sales may be made without notice. If notice is required by law, each Debtor hereby deems ten days advance notice of the time and place of any public or private sale reasonable notification, recognizing that if any portion of the Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, shorter notice may be reasonable. The Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any sale by announcement at the time and place fixed therefor, and such sale may, without further notice,

-23-

be made at the time and place to which it was adjourned. In the event that any sale hereunder is not completed or is defective in the opinion of the Administrative Agent, the Administrative Agent shall have the right to cause subsequent sales to be made hereunder. Any statements of fact or other recitals made in any ▇▇▇▇ of sale, assignment, or other document representing any sale hereunder, including statements relating to the occurrence of an Event of Default, acceleration of the Secured Obligations, notice of the sale, the time, place, and terms of the sale, and other actions taken by the Administrative Agent in relation to the sale may be conclusively relied upon by the purchaser at any sale hereunder. The Administrative Agent may delegate to any agent the performance of any acts in connection with any sale hereunder, including the sending of notices and the conduct of the sale.

     6.6 Application of Proceeds.

          (a) Unless otherwise specified herein or in the Credit Agreement, any cash proceeds received by the Administrative Agent from the sale of, collection of, or other realization upon any part of the Collateral or any other amounts received by the Administrative Agent hereunder may be, at the reasonable discretion of the Administrative Agent (i) held by the Administrative Agent in one or more Cash Collateral Accounts as cash collateral for the Secured Obligations or (ii) applied to the Secured Obligations.

          (b) Amounts applied to the Secured Obligations shall be applied in the following order:

     First, to the payment of the costs and expenses of exercising the Administrative Agent’s rights hereunder, whether expressly provided for herein or otherwise; and

     Second, to the payment of the Secured Obligations in the order set forth in Section 8.03 of the Credit Agreement.

Any surplus cash collateral or cash proceeds held by the Administrative Agent after payment in full of the Secured Obligations and the termination of any commitments of the Administrative Agent to any Debtor shall be paid over to such Debtor or to whomever may be lawfully entitled to receive such surplus.

     6.7 Waiver of Certain Rights. To the full extent each Debtor may do so, such Debtor shall not insist upon, plead, claim, or take advantage of any law providing for any appraisement, valuation, stay, extension, or redemption, and such Debtor hereby waives and releases the same, and all rights to a marshaling of the assets of such Debtor, including the Collateral of such Debtor, or to a sale in inverse order of alienation in the event of foreclosure of the liens and security interests hereby created. Such Debtor shall not assert any right under any law pertaining to the marshaling of assets, sale in inverse order of alienation, the administration of estates of decedents or other matters whatever to defeat, reduce, or affect the right of the Administrative Agent under the terms of this Agreement.

     6.8 Reinstatement. The obligations of each Debtor under this Agreement shall continue to be effective or automatically be reinstated, as the case may be, if at any time payment of any of the Secured Obligations is rescinded or otherwise must be restored or returned by the Administrative Agent upon the insolvency, bankruptcy, dissolution, liquidation, or

-24-

reorganization of any Debtor or any other obligor or otherwise, all as though such payment had not been made.

SECTION 7.

MISCELLANEOUS

     7.1 Amendments. None of the terms or provisions of this Agreement may be waived, amended, supplemented, or otherwise modified except in accordance with Section 10.01 of the Credit Agreement.

     7.3 No Waiver by Course of Conduct; Cumulative Remedies; No Duty. No failure to exercise, nor any delay in exercising, on the part of the Administrative Agent, any right, power, or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power, or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power, or privilege. A waiver by the Administrative Agent of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Administrative Agent would otherwise have on any future occasion. The rights and remedies provided herein and in the other Loan Documents are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law. The powers conferred on Administrative Agent under this Agreement are solely to protect Administrative Agent’s rights under this Agreement and shall not impose any duty upon it to exercise any such powers.

          (b) Each Debtor agrees to pay, and to indemnify and hold the Administrative Agent, the Syndication Agent, and holder of the Secured Obligations, and each sub-agent and Related Party of any of the foregoing Persons harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales, or other taxes which may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement.

          (c) All amounts due under this Section 7.4 shall be payable upon demand therefor. The agreements in this Section shall survive repayment of the Obligations and all other amounts payable under the Credit Agreement and the other Loan Documents.

     7.5 Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Debtor and shall inure to the benefit of the Administrative Agent and the holders of the Secured Obligations and their successors and assigns; provided that no Debtor may assign, transfer, or delegate any of its rights or obligations under this Agreement without the prior written consent of the Administrative Agent.

     7.6 Set-Off. Each Debtor hereby irrevocably authorizes the Administrative Agent, each Lender, each Swing Line Lender, each L/C Issuer, and each of their respective Affiliates at any time and from time to time upon the occurrence and during the continuance of any Event of Default, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, such Swing Line Lender, such L/C Issuer, or any such Affiliate to or for the credit or the account of any Debtor against any and all of the obligations of such Debtor now or hereafter existing under the Credit Agreement, any Guaranty, this Agreement, or under any other Loan Document to such Lender, Swing Line Lender, or L/C Issuer, irrespective of whether or not such Lender, Swing Line Lender, or L/C Issuer shall have made any demand for payment and although such obligations of such Debtor may be contingent or unmatured or are owed to a branch or office of such Lender, Swing Line Lender, or L/C Issuer different from the branch or office holding such deposit or obligated on such indebtedness. Any such set-off shall be subject to the notice requirements of Section 10.08 of the Credit Agreement; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.

     7.7 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by parties hereto in different counterparts), each of which shall be constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof.

Annex I to the
Security Agreement

     This SUPPLEMENT NO. [ ] dated as of [      ] (this “Supplement”), is delivered in connection with (a) the Security Agreement dated as of May 12, 2005 (the “Security Agreement”), among Grant Prideco, Inc., a Delaware corporation (the “Parent”), certain subsidiaries of the Parent (the Parent and such subsidiaries collectively being the “Debtors”), and ▇▇▇▇▇ Fargo Bank, National Association, as administrative agent (in such capacity, the “Administrative Agent”), for the benefit of the holders of the Secured Obligations (as defined therein) and (b) the Subsdiary Guaranty described below.

     A Reference is made to the Credit Agreement dated as of May 12, 2005 (as amended, supplemented, or otherwise modified from time to time, the “Credit Agreement”), among the Parent and certain of its Subsidiaries as Borrowers (such Subsidiaries, together with the Parent, the “Borrowers”), Bank of America, N.A. as Syndication Agent, the Administrative Agent, and the Lenders, Swing Line Lenders, L/C Issuers, and agents from time to time party thereto. Pursuant to the Subsidiary Guaranty dated as of May 12, 2005 (as amended, supplemented, or otherwise modified from time to time, the “Subsidiary Guaranty”), made by the Debtors (other than the Parent), such Debtors have agreed to guarantee, among other things, the full payment and performance of all of the obligations of the Borrowers under the Credit Agreement. Pursuant to the Parent Guaranty dated as of May 12, 2005 (as amended, supplemented, or otherwise modified from time to time, the “Parent Guaranty”, and together with the Subsidiary Guaranty, the “Guaranties”), made by the Parent, the Parent has agreed to guarantee, among other things, the full payment and performance of all of the obligations of the other Borrowers under the Credit Agreement.

     B Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Security Agreement and the Credit Agreement.

     C The Debtors have entered into the Security Agreement and the Guaranties as a condition precedent to the effectiveness of the Credit Agreement. Section 7.12 of the Security Agreement provides that additional Subsidiaries of the Loan Parties may become Debtors under the Security Agreement by execution and delivery of an instrument in the form of this Supplement. Section 6.13 of the Credit Agreement provides that additional Subsidiaries of the Loan Parties must become Guarantors under the Subsidiary Guaranty. The undersigned Subsidiary (the “New Debtor”) is executing this Supplement in accordance with the requirements of the Credit Agreement to become a Debtor under the Security Agreement and a Guarantor under the Subsidiary Guaranty.

     Accordingly, the Administrative Agent and the New Debtor agree as follows:

     SECTION 1. In accordance with Section 7.12 of the Security Agreement, the New Debtor by its signature below becomes a Debtor under the Security Agreement and a Guarantor under the Subsidiary Guaranty with the same force and effect as if originally named therein as a Debtor or Guarantor, as applicable, and the New Debtor hereby (a) agrees to all the terms and provisions of the Security Agreement and the Subsidiary Guaranty applicable to it as a Debtor or Guarantor, as applicable, thereunder and (b) represents and warrants that the representations and

Annex I to Security Agreement

-1-

warranties made by it as a Debtor or Guarantor, as applicable, thereunder are true and correct on and as of the date hereof. The Schedules to the Security Agreement are hereby supplemented by the Schedules attached hereto with respect to the New Debtor. In furtherance of the foregoing, the New Debtor, as security for the payment and performance in full of the Secured Obligations (as defined in the Security Agreement), does hereby create and grant to the Administrative Agent, for the benefit of the holders of the Secured Obligations, a security interest in and lien on all of the New Debtor’s right, title and interest in and to the Collateral of the New Debtor. Each reference to a “Debtor” in the Security Agreement or “Guarantor” in the Subsidiary Guaranty shall be deemed to include the New Debtor.

     SECTION 2. The New Debtor represents and warrants to the Administrative Agent that this Supplement has been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms.

     SECTION 3. This Supplement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

     SECTION 4. Except as expressly supplemented hereby, the Security Agreement and the Subsidiary Guaranty shall remain in full force and effect.

     SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND INTERPRETED AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

     SECTION 6. All communications and notices to the New Debtor under the Security Agreement or the Subsidiary Guaranty shall be in writing and given as provided in Section 7.2 of the Security Agreement to the address for the New Debtor set forth under its signature below.

     SECTION 7. The New Debtor agrees to reimburse the Administrative Agent for its reasonable out-of-pocket expenses in connection with this Supplement, including the reasonable fees, other charges and disbursements of counsel for the Administrative Agent.
