5.3 Change of Jurisdiction of Organization.

5.9 No Transfer of Collateral. Grantor shall not sell, transfer or assign (by operation of law or otherwise) any Collateral without the consent of the Trustee other than as permitted by the Indenture.

Grantor shall permit representatives of Trustee, upon reasonable notice and at any time during normal business hours, to inspect and make abstracts from its books and records pertaining to the Collateral, and shall permit representatives of Trustee to be present at Grantor's place of business to receive copies of all communications and remittances relating to the Collateral, all in such manner as Trustee may reasonably require.

5.12 Insurance. Grantor shall maintain at all times and at its sole expense, with financially sound and reputable insurance companies, insurance policies (i) insuring the Equipment against loss by fire, explosion, theft and such other casualties as from time to time would be insured against by a prudent operator of similar property and (ii) insuring Trustee and the Holders against liability for personal injury and property damage relating to such Equipment, such policies to be in such form and amounts and having such coverage as from time to time would be maintained by a prudent operator of similar property. Each policy or certificate with respect to such insurance shall be endorsed for the benefit of Trustee (including, without limitation, by naming Trustee as an additional named insured or loss payee

as its interest may appear) and such policy or certificate shall be retained by Grantor and a copy or copies of such policy or certificate shall be delivered to Trustee annually together with the Officers' Certificate required to be delivered to Trustee within 90 days after the end of each fiscal year of Grantor pursuant to Section 4.06(a) of the Indenture. Each such policy or a certificate issued to Trustee in respect thereof shall state that such policy cannot be cancelled without thirty (30) days' prior written notice to Trustee. At least thirty (30) days prior to the expiration of any such policy of insurance, Grantor shall provide documentation to Trustee that Grantor is negotiating an extension or renewal of such policy and shall at least five (5) Business Days prior to expiration of any such policy of insurance obtain an extension or renewal policy and an insurance certificate evidencing such renewal or extension and shall give Trustee written notice thereof. If Grantor shall fail to insure such Collateral in accordance with the provisions hereof or if Grantor shall fail to so endorse or to extend or renew, any such insurance policies or certificates with respect thereto, Trustee shall have the right (but shall be under no obligation), to advance funds to procure, renew or extend such insurance (after providing Grantor with at least five (5) Business Days' notice of its intent to advance such funds) and Grantor agrees to reimburse Trustee for any and all costs and expenses thereof, with interest on all such funds from the date advanced at the rate per annum (the "Default Rate") equal to the rate then payable under the Securities. Within five (5) Business Days after making any such advance, Trustee shall give Grantor written notice of the amount and purpose of such advance; provided, however, that failure to give such notice will not relieve Grantor of its obligations to make such reimbursement to Trustee. Unless an Event of Default under the Indenture shall have occurred and shall be continuing, Grantor may determine whether to file a claim for repair or replacement costs or a claim for actual cash value under the relevant insurance policy. Any proceeds of insurance in respect of the Collateral are hereby assigned to Trustee. In case of any loss or damage to any of the Collateral, all proceeds of insurance maintained by Grantor in respect of the Collateral shall be paid to Trustee as Trust Moneys pursuant to the Indenture and shall be subject to retention and disbursement by Trustee in accordance with the terms of the Indenture. The provisions of this Section 5.12 shall not be deemed to limit Grantor's obligations to maintain insurance (or any related obligations) pursuant to any Mortgage or other Security Document.

5.13 Notices. Grantor shall advise Trustee promptly, in reasonable detail, of:

(a) any Lien (other than security interests created hereby or Permitted Liens) on any of the Collateral; and

(b) the occurrence of any other event which could reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(a) So long as it is commercially reasonable to do so, Grantor shall perform and comply in all material respects with all of its obligations under the Contracts constituting Collateral, provided, however, that any such non-performance or non-compliance shall not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(b) Grantor shall not amend, modify, terminate or waive any provision of any Contract in any manner which could reasonably be expected to materially adversely affect the value of the Collateral taken as a whole; provided that the Company may replace a Contract (the "Initial Contract") so long as (i) the contract entered into to replace the Initial Contract (the "Replacement Contract") is subject to the security interest created by this Security Agreement and (ii) the

Replacement Contract is on no materially less favorable terms to the Company than the Initial Contract.

(c) Grantor shall, in its prudent business judgment, exercise promptly and diligently each and every material right which it may have under each Contract; provided Grantor may amend, modify, terminate or waive rights subject to Section 5.15(b) above.

(d) Grantor shall deliver to Trustee a copy of each material demand, notice or document received by it relating in any way to any Contract.

(e) In any suit, proceeding or action brought by Trustee or any Holder under any Contract, Grantor shall save, indemnify and keep Trustee and such Holder harmless from and against any and all expenses, losses, claims, liabilities and damages, as incurred, suffered by reason of any defense, setoff, counterclaim, recoupment or reduction or liability whatsoever of the obligor thereunder, arising out of a breach by Grantor of any obligation thereunder or arising out of any other agreement, indebtedness or liability at any time owing to or in favor of such obligor or its successors from Grantor.

(c) With respect to any Trademarks which are material to its business, Grantor (i) shall maintain such Trademarks in full force free from any claim of abandonment or invalidity for non-use, (ii) shall not fail to maintain the level of the quality of products sold and services rendered under any of such Trademarks at a level at least substantially consistent with the quality of such products and services as of the date hereof, (iii) shall not fail to employ each material Trademark with the appropriate notice of registration, or (iv) shall not fail to do any act or knowingly omit to do any act (or permit a licensee or sublicensee to act or knowingly omit to act) whereby such Trademark may become invalidated.

(g) Grantor shall take all reasonable and necessary steps, as it shall deem appropriate under the circumstances, in accordance with its reasonable business judgment, to maintain and pursue each application (and to obtain the relevant registration) and to maintain to the extent permitted by law each registration of each material Copyright owned by Grantor including, without limitation, filing of applications for renewal, where necessary.

(h) If Grantor shall obtain any rights to any new invention (whether or not patentable), Trade Secret, Trademark, Trademark License, Copyright, Copyright License, Patent or Patent License, then, to the extent that any item enumerated in this sentence would constitute Collateral, the provisions of this Security Agreement shall automatically apply thereto and any such item shall automatically constitute Collateral and shall be subject to the assignment, Lien and security interest created hereby without further action by any party.

If an Event of Default shall occur and be continuing, then and in every such case, Trustee shall have all the rights of a secured party under the UCC (including, without limitation, the right to sell all or any portion of the Collateral in one or more parcels at public or private sale, for cash or credit, or for future delivery and upon such terms as Trustee may determine), shall have all rights now or hereafter existing under all other applicable laws, and, subject to any mandatory requirements of applicable law then in effect, shall have all the rights set forth in this Security Agreement.

8.2 Notice to Obligors and Contract Parties. Upon the request of Trustee at any time after the occurrence and during the continuance of an Event of Default, Grantor shall notify parties to the Contracts constituting Collateral and Account Debtors in respect of any General Intangibles, Instruments and Chattel Paper constituting Collateral that such Collateral has been assigned to Trustee for the ratable benefit of the Holders and that payments in respect thereof shall be made directly to Trustee.

8.3 Proceeds to be Turned Over to Trustee. All proceeds of any Collateral received by Grantor consisting of cash, checks and other near-cash items (collectively, "Cash Proceeds") shall be held by Grantor in trust for Trustee, segregated from other funds of Grantor, and shall, forthwith upon receipt by Grantor be turned over to Trustee in the exact form received by Grantor (duly endorsed by Grantor to Trustee, if required) and held by Trustee in the Note Collateral Account, which shall be maintained under the sole dominion and control of Trustee. Any Cash Proceeds received by Trustee (whether from Grantor or otherwise): (i) if no Event of Default shall have occurred and be continuing, shall be held by Trustee as collateral security for the Obligations (whether matured or unmatured) unless and until delivered to Grantor as provided in the Indenture, and (ii) if an Event of Default shall occur and be continuing, may, in the sole discretion of Trustee, (A) be held by Trustee as collateral security for the Obligations (whether matured or unmatured) and/or (B) then or at any time thereafter may be applied by Trustee, in accordance with the Indenture, for the payment of any expenses incurred by Trustee in enforcing its rights under this Security Agreement. Notwithstanding the foregoing, this Section 8.3 shall not apply to Cash Proceeds received by Grantor in the ordinary course of business prior to the occurrence and continuance of an Event of Default or to proceeds of any Revolver Collateral. All Proceeds while held by Trustee in the Note Collateral Account (or by Grantor in trust for Trustee and the Holders) shall continue to be held as collateral security for the Obligations and shall not constitute payment thereof until applied as provided in Section 8.11.

8.4 Obtaining Possession of the Collateral. If an Event of Default shall occur and be continuing, then and in every such case, Trustee may, but shall not be obligated to, in addition to any other action permitted by law (and not limited in any manner to the remedies contained in the Notes and the Indenture) take one or more of the following actions:

(i) personally, or by agents or attorneys, immediately take possession of the Collateral or any part thereof, from Grantor or any other Person who then has possession of any part thereof with or without notice of process of law, and for that purpose may enter upon Grantor's premises where any of the Collateral is located and remove such Collateral and, in connection with such removal, use any and all services, supplies, aids and other facilities of Grantor;

(ii) sell, assign or otherwise liquidate, or direct Grantor to sell, assign or otherwise liquidate, any or all investments made in whole or in part with the Collateral or any part thereof, and take possession of the proceeds of any such sale, assignment or liquidation; and

(iii) take possession of the Collateral or any part thereof, by directing Grantor in writing to deliver the same to Trustee at any commercially reasonable place or places which Trustee shall reasonably select, in which event Grantor shall at its own expense: (A) forthwith cause the same to be moved to the place or places so designated by Trustee and there delivered to Trustee; (B) store and keep any Collateral so delivered to Trustee at such place or places pending further action by Trustee; and (C) while the Collateral shall be so stored and kept, provide such guards and maintenance services as shall be reasonably necessary to protect the same and to preserve and maintain them in good condition.

Grantor's obligation to deliver the Collateral is of the essence in this Security Agreement. Upon application to a court of equity having jurisdiction, Trustee shall, to the extent permitted by law, be entitled to a decree requiring specific performance by Grantor of such obligation.

8.5 Disposition of Collateral. Trustee will give Grantor reasonable notice of the time and place of any public sale of the Collateral or any part thereof or of the time after which any private sale or any other intended disposition thereof is to be made. Grantor agrees that the requirements of reasonable notice to it shall be met if such notice is delivered (personally, by facsimile transmission or by overnight delivery service) to its address specified in Section 9.4 (or such other address that Grantor may provide to Trustee in writing) at least ten (10) Business Days before the time of any public sale or after which any private sale may be made.

8.6 Additional Non-UCC Remedies. Upon the occurrence and during the continuance of an Event of Default, Trustee, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except as provided in Section 9.5 and except for any notice required by law referred to below) to or upon Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are, to the extent permitted by law, hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker's board or office of Trustee or elsewhere upon such terms and conditions as Trustee may deem advisable and at such prices as Trustee may elect, for cash or on credit or for future delivery without assumption of any credit risk. Trustee or any Holder shall have the right, to the extent permitted by law, upon any such public sale or sales or upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in Grantor (including any rights of stay and/or appraisal), which right or equity is, to the extent permitted by law, hereby waived or released. Grantor hereby waives any claims against Trustee arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price which might have been obtained at a

public sale, even if Trustee accepts the first offer received and does not offer such Collateral to more than one offeree. Grantor further agrees, at Trustee's request, to assemble the Collateral and make it available to Trustee at places which Trustee shall reasonably select, whether at Grantor's premises or elsewhere. Trustee shall apply the net proceeds of any action taken by it pursuant to this Section 8.6, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of Trustee and the Holders hereunder, including, without limitation, reasonable attorneys' fees and disbursements, as provided in Section 8.11, and only after such application and after the payment by Trustee of any other amount required by any provision of law, need Trustee account for the surplus, if any, to Grantor. Grantor further agrees that a breach of any of the covenants contained in this Article VIII will cause irreparable injury to Trustee, that Trustee has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Article VIII shall be specifically enforceable against Grantor, and Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no default has occurred giving rise to the Obligations becoming due and payable prior to their stated maturities. Nothing in this Article VIII shall in any way alter the rights of Trustee under this Security Agreement.

8.7 Certain Sales of Collateral. Grantor recognizes that, by reason of certain prohibitions contained in law, rules, regulations or orders of any Governmental Authority, Trustee may be compelled, with respect to any sale of all or any part of the Collateral, to limit purchasers to those who meet the requirements of such Governmental Authority. Grantor acknowledges that any such sales may be at prices and on terms less favorable than those obtainable through a public sale without such restrictions, and, notwithstanding such circumstances, agrees that any such restricted sale shall not be deemed, solely by virtue thereof, not to have been made in a commercially reasonable manner.

8.8 Certain Remedies in Respect of Intellectual Property. If an Event of Default shall occur and shall be continuing, in addition to the other rights and remedies provided for herein or otherwise available to it, Trustee may license or sublicense (whether general, special or otherwise, and whether on an exclusive or non-exclusive basis) all or any portions of the Intellectual Property throughout the world for such term or terms, on such conditions and in such manner as Trustee shall determine. Upon request by Trustee, Grantor shall execute and deliver to Trustee any powers of attorney, in form and substance satisfactory to Trustee, for the implementation of any assignment, license, sublicense, grant of option, sale or other disposition of any Intellectual Property. In the event of any sale, assignment, or other disposition of any of the Intellectual Property, the goodwill connected with and symbolized by the Intellectual Property subject to such disposition shall be included in such sale, assignment or other disposition.

8.9 Specific Performance. In addition to any of the other rights and remedies hereunder, Trustee shall have the right to institute a proceeding seeking specific performance in connection with any of the agreements or obligations hereunder.

8.10 Recourse. Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to satisfy the Obligations. Grantor shall also be liable for all expenses of Trustee or any Holder incurred in connection with collecting such deficiency, including, without limitation, the fees and disbursements of any attorneys employed by Trustee to collect such deficiency.

8.11 Application of Proceeds. The net proceeds received by Trustee in respect of any sale of, collection from or other realization upon all or any part of the Collateral pursuant to the exercise by Trustee of its remedies provided in this Article VIII shall be applied (after deduction of amounts permitted or required pursuant to this Article VIII), together with any other sums then held by Trustee pursuant to this Security Agreement, promptly by Trustee in the manner set forth in the Indenture.

8.12 Expenses; Attorneys Fees. Grantor shall upon demand pay to Trustee the amount of any and all reasonable expenses, including the reasonable fees and expenses of its counsel and the reasonable fees and expenses of any experts and agents which Trustee may incur in connection with (i) the collection of the Obligations, (ii) the enforcement and administration of this Security Agreement and any consent, amendment, waiver or other modification to this Security Agreement, (iii) the custody or preservation of, or the sale of, collection from, or other realization upon, any of the Collateral, (iv) the exercise, protection or enforcement of any of the rights of Trustee or any other secured party hereunder, (v) the failure by Grantor to perform or observe any of the provisions hereof, (vi) the creation and perfection of Liens in favor of the Trustee for the benefit of the Holders, including, without limitation, the filing or recording of financing statements and other documents (including all taxes in connection therewith) in public offices, search fees and the reasonable fees, expenses and disbursements of any counsel providing any opinions in respect of the Collateral or the Liens created pursuant to the Security Documents, (vii) the payment or discharge of any taxes, insurance premiums or encumbrances, (viii) defending or prosecuting any actions or proceedings arising out of or related to the transactions to which this Security Agreement relates, (ix) otherwise protecting, maintaining or preserving the Collateral, or the enforcing, foreclosing, retaking, holding, storing, processing, selling or otherwise realizing upon the Collateral and Trustee's security interest therein, whether through judicial proceedings or otherwise, (x) any refinancing or restructuring of the credit arrangements pursuant to the Indenture, including a "work-out," or pursuant to any insolvency or bankruptcy cases or proceedings, and (xi) the failure by Grantor to perform or observe any of the provisions of this Security Agreement. All amounts payable by Grantor under this Section 8.12 shall be due upon demand and shall be part of the Obligations. Grantor's obligations under this Section 8.12 shall survive the termination of this Security Agreement and the discharge of Grantor's other obligations hereunder.

8.13 Limitation on Duties Regarding Preservation of Collateral. Trustee's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as Trustee (in its commercial and not in its trust capacity) deals with similar property for its own account.

(a) Trustee shall have no obligation to take any steps to preserve rights against prior parties to any Collateral.

(b) Neither Trustee nor any Holder, nor any of their respective directors, officers or employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of Grantor or otherwise.

(d) The powers conferred on Trustee and the Holders hereunder are solely to protect Trustee's and the Holders' interests in the Collateral and shall not impose any duty upon Trustee or any Holder to exercise any such powers.

(e) Trustee and the Holders shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their offices, directors, employees or agents shall be responsible to Grantor for any act or failure to act hereunder, except for their own negligence or willful misconduct.

(f) Beyond the duties set forth in this Section 8.13 and the exercise of reasonable care in custody thereof, Trustee shall have no duty as to the collection of any Collateral in its possession or control or in the possession or control of any agent or nominee of Trustee, or any income thereon.

(g) Trustee shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if such Collateral is accorded treatment substantially

equivalent to that which Trustee, in its individual capacity, accords its own property, it being understood that Trustee shall not have responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any Collateral, whether or not Trustee or any other Secured Party has or is deemed to have knowledge of such matters, or (ii) taking any necessary steps to preserve rights against any Person with respect to any Collateral.

ARTICLE IX
MISCELLANEOUS

9.1 Indemnity. Grantor agrees to indemnify, reimburse and hold Trustee, the Holders and their respective officers, directors, partners, members, employees and representatives ("Indemnitees") harmless from any and all liabilities, obligations, losses, damages, penalties, claims, actions, judgments, suits, costs or expenses or disbursements (including attorneys' fees and expenses) for whatsoever kind or nature which may be imposed on, asserted against or incurred by any of the Indemnitees in any way relating to or arising out of this Security Agreement, any other Security Agreement, the Indenture, the Notes, the Guarantees, the Intercreditor Agreement, the Registration Rights Agreement or any of the transactions contemplated hereby or thereby. The obligations of Grantor under this Section 9.1 shall be secured hereby and shall survive payment and performance or discharge of the Obligations and the termination of this Security Agreement for the two years following such payment and performance or discharge; provided that, if during such two year period any Indemnitee gives notice to Grantor of any potential claim under this Section 9.1, then this Section 9.1 shall survive indefinitely until any such potential claim is resolved in a manner satisfactory to Trustee.

9.2 Governing Law. THIS SECURITY AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR PROPERTY ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF NEW YORK.

9.3 Consent to Jurisdiction and Service Process. ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST GRANTOR WITH RESPECT TO THIS SECURITY AGREEMENT MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE OF NEW YORK AND BY EXECUTION AND DELIVERY OF THIS SECURITY AGREEMENT GRANTOR, TO THE EXTENT PERMITTED BY LAW, ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS SECURITY AGREEMENT. GRANTOR DESIGNATES AND APPOINTS CT CORPORATION SYSTEM, WITH AN ADDRESS AT 0000 XXXXXXXX, XXX XXXX, XXX XXXX 00000 AND SUCH OTHER PERSONS AS MAY HEREAFTER BE SELECTED BY GRANTOR IRREVOCABLY AGREEING IN WRITING TO SO SERVE, AS ITS AGENT TO RECEIVE ON ITS BEHALF IN NEW YORK, NEW YORK, SERVICE OF ALL PROCESS IN ANY SUCH PROCEEDINGS IN ANY SUCH COURT, SUCH SERVICE BEING HEREBY ACKNOWLEDGED BY GRANTOR TO BE EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT. A COPY OF SUCH PROCESS SO SERVED SHALL BE MAILED BY REGISTERED OR CERTIFIED MAIL TO GRANTOR AT ITS ADDRESS PROVIDED FOR IN SECTION 9.4 EXCEPT THAT UNLESS OTHERWISE PROVIDED BY APPLICABLE LAW, ANY FAILURE TO MAIL SUCH COPY SHALL NOT AFFECT THE VALIDITY OF SERVICE OF PROCESS. IF ANY

AGENT APPOINTED BY GRANTOR REFUSES TO RECEIVE AND FORWARD SUCH SERVICE, GRANTOR HEREBY AGREES THAT SERVICE UPON IT BY DELIVERY SHALL CONSTITUTE SUFFICIENT NOTICE. NOTHING HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF TRUSTEE OR ANY HOLDER TO BRING PROCEEDINGS AGAINST GRANTOR IN THE COURTS OF ANY OTHER JURISDICTION.

9.4 Notices. Except as otherwise expressly provided herein, all notices, requests and demands to or upon the respective parties hereto to be effective shall be in writing (including by telecopy), and shall be deemed to have been duly given or made when delivered by hand, or in the case of telecopy notice, when sent by transmittal on a Business Day, or in the case of a nationally recognized overnight courier service, one business day after delivery to such courier service, addressed, in the case of each party hereto, at its address specified below, or to such other address as may be designated by any party in a written notice to the other party hereto.

9.5 Grantor Remains Liable. Anything herein to the contrary notwithstanding, (i) Grantor shall remain liable under the Contracts and agreements included in the Collateral to the extent set forth therein to perform all of the duties and obligations thereunder to the same extent as if this Security Agreement had not been executed, (ii) the exercise by Trustee or any holder of any of the rights hereunder shall not release Grantor from any of its duties or obligations under the Contracts and agreements included in the Collateral, and (iii) Trustee shall not have any obligation or liability under the Contracts and agreements included in the Collateral by reason of this Security Agreement, nor shall Trustee be obligated to perform any of the obligations or duties of Grantor thereunder or to take any action to collect or enforce any claim for payment assigned hereunder.

9.6 Appointment as Trustee. The actions of Trustee hereunder are subject to the provisions of the Indenture. Trustee shall have the right hereunder to make demands, to give notices, to exercise or refrain from exercising any rights, and to take or refrain from taking action (including, without limitation, the release or substitution of Collateral), in accordance with this Security Agreement and the Indenture. Trustee may resign and a successor Trustee may be appointed in the manner provided in the Indenture. Upon the acceptance of any appointment as Trustee by a successor Trustee, that successor Trustee shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Trustee under this Security Agreement, and the retiring Trustee shall thereupon be discharged from its duties and obligations under this Security Agreement. After any retiring Trustee's resignation, the provisions of this Security Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it under this Security Agreement while it was Trustee.

9.7 Trustee May Perform. If Grantor shall fail to do any act or thing that it has covenanted to do hereunder or if any warranty on the part of Grantor contained herein shall be breached, Trustee or any Holder may (but shall not be obligated to), after providing Grantor with at least five (5) Business Days' notice, do the same or cause it to be done or remedy any such breach, and may expend funds for such purpose. Any and all amounts so expended by Trustee or such Holder shall be paid by Grantor promptly upon demand therefor, with interest at the Default Rate during the period from and including the date on which such funds were so expended to the date of repayment. Grantor's obligations under this Section 9.7 shall survive the termination of this Security Agreement and the discharge of Grantor's other obligations under this Security Agreement.

9.8 Authority of Trustee. Grantor acknowledges that the rights and responsibilities of Grantor under this Security Agreement with respect to any action taken by Trustee or the exercise or non-exercise by Trustee of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as between Trustee and the Holders, be governed by the Indenture and by such other agreements with respect thereto as may exist from time to time among them, but, as between Trustee and Grantor, Trustee shall be conclusively presumed to be acting as agent for the Holders with full and valid authority so to act or refrain from acting, and Grantor shall be under no obligation, or entitlement, to make any inquiry respecting such authority.

9.9 Successors and Assigns. This Security Agreement shall create a continuing security interest in the Collateral and shall be binding upon and inure to the benefit of Grantor, Trustee, the Holders, all future holders of the Obligations and their respective successors and permitted assigns, except that Grantor may not assign or transfer any of its rights or obligations under this Security Agreement without the prior written consent of Trustee. Trustee may assign its rights under this Security Agreement to one or more permitted assignees. Upon any such assignment, the assignee shall succeed to all of Trustee's rights and powers hereunder. No other persons (including, without limitation, any other creditors of Grantor) other than a permitted assignee of Trustee shall have any interest herein or any right or benefit with respect hereto.

9.10 Amendments in Writing: No Waiver; Cumulative Remedies.

(a) Subject to the provisions of Article Nine of the Indenture, none of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by Grantor and Trustee, provided that any provision of this Security Agreement imposing obligations on Grantor may be waived by Trustee in a written instrument executed solely by Trustee.

(b) In the event Trustee shall have instituted any proceeding to enforce any right, power or remedy under this Security Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to Trustee, then and in every such case, Grantor, Trustee and each Holder, except as may be otherwise determined in such proceeding, shall be restored to their respective former positions and rights hereunder with respect to the Collateral, and all rights, remedies and powers of Trustee and the Holders, except as may be otherwise determined in such proceeding, shall continue as if no such proceeding had been instituted.

(c) No failure or delay on the part of Trustee in exercising any right, power or privilege hereunder and no course of dealing between Grantor and Trustee shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by Trustee of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which Trustee would otherwise have on any future occasion. The rights and remedies herein expressly provided are cumulative and may be exercised singly or concurrently and as often and in such order as Trustee deems expedient and are not exclusive of

any rights or remedies which Trustee would otherwise have whether by agreement or now or hereafter existing under applicable law. No notice to or demand on Grantor in any case shall entitle Grantor to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of Trustee to any other or future action in any circumstances without notice or demand.

9.11 Termination. When the Obligations (other than any obligations arising under the proviso to Section 9.1) have been indefeasibly paid and performed in full, this Security Agreement shall terminate, and Trustee, at the request and sole expense of Grantor, shall execute and deliver to Grantor the proper instruments (including UCC termination statements) acknowledging the termination of this Security Agreement, and shall duly assign, transfer and deliver to Grantor, without recourse, representation or warranty of any kind whatsoever, such of the Collateral as may be in possession of Trustee and has not theretofore been disposed of, applied or released, including the release and cancellation of all licenses and rights referred to in Section 6.1(l); provided, however, that any licenses of sublicenses granted by Trustee pursuant to Section 8.8 shall continue to be in full force and effect in accordance with their terms.

9.12 Release of Collateral. Reference is hereby made to Article Eleven of the Indenture for provisions which discuss the release of the Collateral from the Liens created by this Security Agreement.

9.13 Headings Descriptive. The headings of the several Articles, Sections and subsections of this Security Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Security Agreement.

9.14 Severability. In case any provision in or obligation under this Security Agreement shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions hereof, or of such provision in any other jurisdiction, shall not in any way be affected or impaired thereby.

9.15 Other Security. To the extent that the Obligations are now or hereafter secured by property other than the Collateral or are now or hereafter secured by the guarantee, endorsement or property of any other Person, then Trustee shall have the right in its sole discretion to pursue, relinquish, subordinate, modify or take any other action with respect thereto, without in any way modifying or affecting any of Trustee's or any Holder's rights and remedies hereunder.

9.16 Execution in Counterparts. This Security Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original, but all such counterparts together shall constitute one and the same agreement.

9.17 Obligations Absolute. All obligations of Grantor hereunder shall be absolute and unconditional irrespective of:

(a) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, liquidation or the like of Grantor;

(b) any lack of validity or enforceability of this Security Agreement, any other Security Document, the Notes, the Indenture, the Registration Rights Agreement, the Intercreditor Agreement or the Guarantees or any other agreement or instrument relating to any of the foregoing;

(c) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure from this Security Agreement, any other Security Document, the Notes, the Indenture, the Registration Rights Agreement, the Intercreditor Agreement or the Guarantees or any other agreement or

instrument relating to any of the foregoing (except to the extent specified in such change, amendment or waiver);

(d) any exchange, release or non-perfection of any other collateral, or any release or amendment or waiver of or consent to any departure from any guarantee, for all or any of the Obligations; or

(e) any exercise or non-exercise, or any waiver of, any right, remedy, power or privilege under or in respect of this Security Agreement, any other Security Document, the Notes, the Indenture, the Registration Rights Agreement, the Intercreditor Agreement or the Guarantees or any other agreement or instrument relating to any of the foregoing, except as specifically set forth in a waiver granted pursuant to the provisions of the Indenture.

9.18 Limitation on Interest Payable. It is the intention of the parties to conform strictly to the usury laws, whether state or federal, that are applicable to the transaction of which this Security Agreement is a part. All agreements between Grantor and Trustee, whether now existing or hereafter arising and whether oral or written, are hereby expressly limited so that in no contingency or event whatsoever shall the amount paid or agreed to be paid by Grantor for the use, forbearance or detention of the money to be loaned or advanced under this Security Agreement, any other Security Document, the Notes, the Indenture, the Registration Rights Agreement, the Intercreditor Agreement or the Guarantees or any other agreement or instrument relating to any of the foregoing, or for the payment or performance of any covenant or obligation contained herein or therein, exceed the maximum amount permissible under applicable federal or state usury laws. If under any circumstances whatsoever fulfillment of any such provision, at the time performance of such provision shall be due, shall involve exceeding the limit of validity prescribed by law, then the obligation to be fulfilled shall be reduced to the limit of such validity. If under any circumstances Grantor shall have paid an amount deemed interest by applicable law, which would exceed the highest lawful rate, such amount that would be excessive interest under applicable usury laws shall be applied to the reduction of the principal amount owing in respect of the Obligations and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal and any other amounts due hereunder, the excess shall be refunded to Grantor. All sums paid or agreed to be paid for the use, forbearance or detention of the principal under any extension of credit or advancement of funds by Trustee or any Holder, shall, to the extent permitted by applicable law, and to the extent necessary to preclude exceeding the limit of validity prescribed by law, be amortized, prorated, allocated and spread from the date of this Security Agreement until payment in full of the Obligations so that the actual rate of interest on account of such principal amounts is uniform throughout the term hereof.

9.19 Indenture Controls. All terms, covenants, conditions, provisions and requirements of the Indenture are incorporated by reference in this Security Agreement. In the event of any conflict or inconsistency between the provisions of this Security Agreement and those of the Indenture, including any conflicts or inconsistencies in any definitions herein or therein, except to the extent that new definitions are set forth herein for such terms, the provisions or definitions of the Indenture shall govern.

9.20 Trust Indenture Act Controls. If any provision of this Security Agreement limits, qualifies or conflicts with the duties imposed by the TIA, the duties imposed by the TIA shall control.

9.21 Notice under ORS 746.201. In compliance with ORS 746.201, this Security Agreement contains the following warning, which Grantor acknowledges:

WARNING

UNLESS YOU (OREGON STEEL XXXXX, INC.) PROVIDE US (BENEFICIARY) WITH EVIDENCE OF THE INSURANCE COVERAGE AS REQUIRED BY OUR CONTRACT OR

LOAN AGREEMENT, WE MAY PURCHASE INSURANCE AT YOUR EXPENSE TO PROTECT OUR INTEREST. THIS INSURANCE MAY, BUT NEED NOT, ALSO PROTECT YOUR INTEREST. IF THE COLLATERAL BECOMES DAMAGED, THE COVERAGE WE PURCHASE MAY NOT PAY ANY CLAIM YOU MAKE OR ANY CLAIM MADE AGAINST YOU. YOU MAY LATER CANCEL THIS COVERAGE BY PROVIDING EVIDENCE THAT YOU HAVE OBTAINED PROPERTY COVERAGE ELSEWHERE.

YOU ARE RESPONSIBLE FOR THE COST OF ANY INSURANCE PURCHASED BY US. THE COST OF THIS INSURANCE MAY BE ADDED TO YOUR CONTRACT OR LOAN BALANCE. IF THE COST IS ADDED TO YOUR CONTRACT OR LOAN BALANCE, THE INTEREST RATE ON THE UNDERLYING CONTRACT OR LOAN WILL APPLY TO THIS ADDED AMOUNT. THE EFFECTIVE DATE OF COVERAGE MAY BE THE DATE YOUR PRIOR COVERAGE LAPSED OR THE DATE YOU FAILED TO PROVIDE PROOF OF COVERAGE.

THE COVERAGE WE PROVIDE MAY BE CONSIDERABLY MORE EXPENSIVE THAN INSURANCE YOU CAN OBTAIN ON YOUR OWN AND MAY NOT SATISFY ANY NEED FOR PROPERTY DAMAGE COVERAGE OR ANY MANDATORY LIABILITY INSURANCE REQUIREMENTS IMPOSED BY APPLICABLE LAW.

9.22 Intercreditor Agreement. The rights and obligations of the parties hereto are subject to the Intercreditor Agreement.
