Each Grantor agrees, at its own expense, to execute, acknowledge, deliver and cause to be duly filed all such further instruments and documents and take all such actions as are necessary or as the Collateral Agent may from time to time request to better assure, preserve, protect and perfect the Security Interest and the rights and remedies created hereby, including the payment of any fees and taxes required in connection with the execution and delivery of this Agreement, the granting of the Security Interest and the filing of any financing statements (including fixture filings) or other documents in connection herewith or therewith. If any amount payable under or in connection with any of the Collateral shall be or become evidenced by any promissory note or other instrument, such note or instrument shall be promptly pledged and delivered to the Collateral Agent, duly endorsed in a manner satisfactory to the Collateral Agent.</P>
<P>&#9;SECTION 4.05. <U>Inspection and Verification</U>. The Collateral Agent and such Persons as the Collateral Agent may reasonably designate shall have the right to inspect the Collateral, all records related thereto (and to make extracts and copies from such records) and the premises upon which any of the Collateral is located, at reasonable times and intervals during normal business hours upon reasonable advance notice to the respective Grantor and to verify under reasonable procedures the validity, amount, quality, quantity, value, condition and status of the Collateral. The Collateral Agent shall have the absolute right to share any information it gains from such inspection or verification with any Secured Party in accordance with and subject to the provisions set forth in Section 8.12 of the Reimbursement Agreement.</P>
<P>&#9;SECTION 4.06. <U>Taxes; Encumbrances</U>. At its option, the Collateral Agent may discharge past due taxes, assessments, charges, fees, Liens, security interests or other encumbrances at any time levied or placed on the Collateral and not permitted pursuant to Section&nbsp;6.02 of the Revolving Credit Agreement, and may pay for the maintenance and preservation of the Collateral, in each case to the extent any Grantor fails to do so as required by the Reimbursement Agreement or this Agreement and such failure shall continue beyond any applicable notice and cure period, and each Grantor jointly and severally agrees to reimburse the Collateral Agent on demand for any payment made or any expense incurred by the Collateral Agent pursuant to the foregoing authorization; <U>provided</U>, <U>however</U>, that nothing in this Section&nbsp;4.06 shall be interpreted as excusing any Grantor from the performance of, or imposing any obligation on the Collateral Agent or any Secured Party to cure or perform, any covenants or other promises of any Grantor with respect to taxes, assessments, charges, fees, liens, security interests or other encumbrances and maintenance as set forth herein or in the other Reimbursement Documents.</P>
<P>&#9;SECTION 4.07. <U>Assignment of Security Interest</U>. If at any time any Grantor shall take a security interest in any property of an Account Debtor or any other Person to secure payment and performance of an Account, such Grantor shall promptly assign such security interest to the Collateral Agent to the extent permitted by any contracts or arrangements to which such property is subject. Such assignment need not be filed of public record unless necessary to continue the perfected status of the security interest against creditors of and transferees from the Account Debtor or other Person granting the security interest.</P>
<P>&#9;SECTION 4.08. <U>Continuing Obligations of the Grantors</U>. Each Grantor shall remain liable to observe and perform all the conditions and obligations to be observed and performed by it under each contract, agreement or instrument relating to the Collateral, all in accordance with the terms and conditions thereof, and each Grantor jointly and severally agrees to indemnify and hold harmless the Collateral Agent and the Secured Parties from and against any and all liability for such performance, <U>provided</U> that such indemnity shall not be available, as to the Collateral Agent and the Secured Parties, to the extent that such liability resulted from the gross negligence or willful misconduct of the Collateral Agent or a Secured Party.</P>
<P>&#9;SECTION 4.09. <U>Use and Disposition of Collateral</U>. None of the Grantors shall make or permit to be made an assignment, pledge or hypothecation of the Collateral or shall grant any other Lien in respect of the Collateral, except as expressly permitted by Section&nbsp;6.02 of the Revolving Credit Agreement. None of the Grantors shall make or permit to be made any transfer of the Collateral and each Grantor shall remain at all times in possession of the Collateral owned by it, except that (a)&nbsp;Inventory may be sold or consigned in the ordinary course of business and (b)&nbsp;unless and until the Collateral Agent shall notify the Grantors that an Event of Default shall have occurred and be continuing and that during the continuance thereof the Grantors shall not sell, convey, lease, assign, transfer or otherwise dispose of any Collateral (which notice may be given by telephone if promptly confirmed in writing), the Grantors may use and dispose of the Collateral in any lawful manner not inconsistent with the provisions of this Agreement, the Reimbursement Agreement or any other Reimbursement Document. Without limiting the generality of the foregoing, each Grantor agrees that it shall not permit any material Inventory to be in the possession or control of any warehouseman, bailee, agent or processor at any time unless such warehouseman, bailee, agent or processor shall have been notified of the Security Interest and shall have agreed in writing to hold the Inventory subject to the Security Interest and the instructions of the Collateral Agent and to waive and release any Lien held by it with respect to such Inventory, whether arising by operation of law or otherwise.</P>
<P>&#9;SECTION 4.10. <U>Limitation on Modification of Accounts</U>.&nbsp;&nbsp;None of the Grantors will, without the Collateral Agent's prior written consent, which consent shall not be unreasonably withheld, grant any extension of the time of payment of any of the Accounts Receivable, compromise, compound or settle the same for less than the full amount thereof, release, wholly or partly, any Person liable for the payment thereof or allow any credit or discount whatsoever thereon, other than extensions, credits, discounts, compromises or settlements granted or made in the ordinary course of business and consistent with its current practices.</P>
<P>&#9;SECTION 4.11. <U>Insurance</U>. The Grantors, at their own expense, shall maintain or cause to be maintained insurance covering physical loss or damage to the Inventory and Equipment in accordance with Section&nbsp; 5.08 of the Reimbursement Agreement. Each Grantor irrevocably makes, constitutes and appoints the Collateral Agent (and all officers, employees or agents designated by the Collateral Agent) as such Grantor's true and lawful agent (and attorney-in-fact) for the purpose, during the continuance of an Event of Default, of making, settling and adjusting claims in respect of Collateral under policies of insurance, endorsing the name of such Grantor on any check, draft, instrument or other item of payment for the proceeds of such policies of insurance and for making all determinations and decisions with respect thereto. In the event that any Grantor at any time or times shall fail to obtain or maintain any of the policies of insurance required hereby or to pay any premium in whole or part relating thereto, the Collateral Agent may, but is under no obligation to, without waiving or releasing any obligation or liability of the Grantors hereunder or any Event of Default, in its reasonable discretion, obtain and maintain such policies of insurance and pay such premium and take any other actions with respect thereto as the Collateral Agent deems advisable. All sums disbursed by the Collateral Agent in connection with this Section&nbsp;4.11, including reasonable attorneys' fees, court costs, expenses and other charges relating thereto, shall be payable, upon demand, by the Grantors to the Collateral Agent and shall be additional Reimbursement Obligations secured hereby.</P>
<P>&#9;SECTION 4.12. <U>Legend.</U> If any Accounts Receivable of any Grantor are evidenced by Chattel Paper, such Grantor shall legend, in form and manner reasonably satisfactory to the Collateral Agent, such Accounts Receivable and its books, records and documents evidencing or pertaining thereto with an appropriate reference to the fact that such Accounts Receivable have been assigned to the Collateral Agent for the benefit of the Secured Parties and that the Collateral Agent has a security interest therein.</P>
<P>&#9;SECTION 4.13. <U>Covenants Regarding Patent, Trademark and Copyright Collateral</U>. (a) Each Grantor agrees that it will not, and will not permit any of its licensees to, do any act, or omit to do any act, whereby any Patent which is material to the conduct of such Grantor's business may become invalidated or dedicated to the public, and agrees that it shall continue to mark, to the extent permitted by existing technology, any products covered by a Patent with the relevant patent number as necessary and sufficient to establish and preserve its maximum rights under applicable patent laws pursuant to which each such Patent is issued.</P>
<P>&#9;(b) Each Grantor (either itself or through its licensees or its sublicensees) will, for each Trademark material to the conduct of such Grantor's business, (i) maintain such Trademark in full force free from any claim of abandonment or invalidity for non-use, (ii) maintain the quality of products and services offered under such Trademark sufficient to preclude any findings of abandonment, (iii) display such Trademark with notice of Federal or foreign registration to the extent necessary and sufficient to establish and preserve its maximum rights under applicable law pursuant to which each such Trademark is issued and (iv) not knowingly use or knowingly permit the use of such Trademark in violation of any third party rights.</P>
<P>&#9;(c) Each Grantor (either itself or through licensees) will, for each work covered by a material Copyright, continue to publish, reproduce, display, adopt and distribute the work with appropriate copyright notice as necessary and sufficient to establish and preserve its maximum rights under applicable copyright laws pursuant to which each such Copyright is issued. </P>
<P>&#9;(d) Each Grantor shall notify the Collateral Agent immediately if it knows or has reason to know that any such Patent, Trademark or Copyright material to the conduct of its business may become abandoned, lost or dedicated to the public, or of any adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, United States Copyright Office or any court or similar office of any country) regarding such Grantor's ownership of any such Patent, Trademark or Copyright, its right to register the same, or to keep and maintain the same.</P>
<P>&#9;(e) In no event shall any Grantor, either itself or through any agent, employee, licensee or designee, file an application for any Patent, Trademark or Copyright (or for the registration of any Trademark or Copyright) with the United States Patent and Trademark Office, United States Copyright Office or any office or agency in any political subdivision of the United States or in any other country or any political subdivision thereof, unless it promptly thereafter informs the Collateral Agent, and, upon request of the Collateral Agent, executes and delivers any and all agreements, instruments, documents and papers as are necessary or as the Collateral Agent may request to evidence and perfect the Collateral Agent's security interest in such Patent, Trademark or Copyright, and each Grantor hereby appoints the Collateral Agent as its attorney-in-fact to execute and file such writings for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; such power, being coupled with an interest, is irrevocable.</P>
<P>&#9;(f) Each Grantor will take all necessary steps that are consistent with the practice in any proceeding before the United States Patent and Trademark Office, United States Copyright Office or any office or agency in any political subdivision of the United States or in any other country or any political subdivision thereof, to maintain and pursue each material application relating to the Patents, Trademarks and/or Copyrights (and to obtain the relevant grant or registration) and to maintain each issued Patent and each registration of the Trademarks and Copyrights that is material to the conduct of any Grantor's business, including timely filings of applications for renewal, affidavits of use, affidavits of incontestability and payment of maintenance fees, and, if consistent with good business judgment, to initiate opposition, interference and cancellation proceedings against third parties.</P>
<P>&#9;(g) In the event that any Grantor has reason to believe that any Collateral consisting of a Patent, Trademark or Copyright material to the conduct of any Grantor's business has been or is about to be infringed, misappropriated or diluted by a third party, such Grantor promptly shall notify the Collateral Agent and shall, if consistent with good business judgment, promptly sue for infringement, misappropriation or dilution and to recover any and all damages for such infringement, misappropriation or dilution, and take such other actions as are appropriate under the circumstances to protect such Collateral.</P>
<P>&#9;(h) Upon and during the continuance of an Event of Default, each Grantor shall use its best efforts to obtain all requisite consents or approvals from the licensor of each Copyright License, Patent License or Trademark License to effect the assignment of all of such Grantor's right, title and interest thereunder to the Collateral Agent or its designee.</P>
<P ALIGN="CENTER">ARTICLE V</P>
<U><P ALIGN="CENTER">Power of Attorney</P>
</U><P>&#9;Each Grantor irrevocably makes, constitutes and appoints the Collateral Agent (and all officers, employees or agents designated by the Collateral Agent) as such Grantor's true and lawful agent and attorney-in-fact, and in such capacity the Collateral Agent shall have the right, with power of substitution for each Grantor and in each Grantor's name or otherwise, for the use and benefit of the Collateral Agent and the Secured Parties, upon the occurrence and during the continuance of an Event of Default (a)&nbsp;to receive, endorse, assign and/or deliver any and all notes, acceptances, checks, drafts, money orders or other evidences of payment relating to the Collateral or any part thereof; (b)&nbsp;to demand, collect, receive payment of, give receipt for and give discharges and releases of all or any of the Collateral; (c)&nbsp;to sign the name of any Grantor on any invoice or bill of lading relating to any of the Collateral; (d)&nbsp;to send verifications of Accounts Receivable to any Account Debtor; (e)&nbsp;to commence and prosecute any and all suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect or otherwise realize on all or any of the Collateral or to enforce any rights in respect of any Collateral; (f)&nbsp;to settle, compromise, compound, adjust or defend any actions, suits or proceedings relating to all or any of the Collateral; (g)&nbsp;to notify, or to require any Grantor to notify, Account Debtors to make payment directly to the Collateral Agent; and (h)&nbsp;to use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with all or any of the Collateral, and to do all other acts and things necessary to carry out the purposes of this Agreement, as fully and completely as though the Collateral Agent were the absolute owner of the Collateral for all purposes; <U>provided</U>, <U>however</U>, that nothing herein contained shall be construed as requiring or obligating the Collateral Agent or any Secured Party to make any commitment or to make any inquiry as to the nature or sufficiency of any payment received by the Collateral Agent or any Secured Party, or to present or file any claim or notice, or to take any action with respect to the Collateral or any part thereof or the moneys due or to become due in respect thereof or any property covered thereby, and no action taken or omitted to be taken by the Collateral Agent or any Secured Party with respect to the Collateral or any part thereof shall give rise to any defense, counterclaim or offset in favor of any Grantor or to any claim or action against the Collateral Agent or any Secured Party. It is understood and agreed that the appointment of the Collateral Agent as the agent and attorney-in-fact of the Grantors for the purposes set forth above is coupled with an interest and is irrevocable. The provisions of this Section shall in no event relieve any Grantor of any of its obligations hereunder or under any other Reimbursement Document with respect to the Collateral or any part thereof or impose any obligation on the Collateral Agent or any Secured Party to proceed in any particular manner with respect to the Collateral or any part thereof, or in any way limit the exercise by the Collateral Agent or any Secured Party of any other or further right which it may have on the date of this Agreement or hereafter, whether hereunder, under any other Reimbursement Document, by law or otherwise.</P>
<P ALIGN="CENTER">ARTICLE VI</P>
<U><P ALIGN="CENTER">Remedies</P>
</U><P>&#9;SECTION 6.01. <U>Remedies upon Default</U>. Upon the occurrence and during the continuance of an Event of Default, each Grantor agrees to deliver each item of Collateral to the Collateral Agent on demand, and it is agreed that the Collateral Agent shall have the right to take any of or all the following actions at the same or different times: (a) with respect to any Collateral consisting of Intellectual Property, on demand, to cause the Security Interest to become an assignment, transfer and conveyance of any of or all such Collateral by the applicable Grantors to the Collateral Agent (except to the extent assignment, transfer or conveyance thereof would result in a loss of said Intellectual Property), or to license or sublicense, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis, any such Collateral throughout the world on such terms and conditions and in such manner as the Collateral Agent shall determine (other than in violation of any then-existing licensing arrangements to the extent that waivers cannot be obtained), and (b) with or without legal process and with or without prior notice or demand for performance, to take possession of the Collateral and without liability for trespass to enter any premises where the Collateral may be located for the purpose of taking possession of or removing the Collateral and, generally, to exercise any and all rights afforded to a secured party under the UCC or other applicable law. Without limiting the generality of the foregoing, each Grantor agrees that the Collateral Agent shall have the right, subject to the mandatory requirements of applicable law, to sell or otherwise dispose of all or any part of the Collateral, at public or private sale or at any broker's board or on any securities exchange, for cash, upon credit or for future delivery as the Collateral Agent shall deem appropriate. The Collateral Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale the Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each such purchaser at any such sale shall hold the property sold absolutely, free from any claim or right on the part of any Grantor, and each Grantor hereby waives (to the extent permitted by law) all rights of redemption, stay and appraisal which such Grantor now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted.</P>
<P>&#9;The Collateral Agent shall give the Grantors 10&nbsp;days' written notice (which each Grantor agrees is a "reasonable authenticated notification of disposition" within the meaning of Section&nbsp;9-611 of the UCC or its equivalent in other jurisdictions) of the Collateral Agent's intention to make any sale of Collateral. Such notice, in the case of a public sale, shall state the time and place for such sale and, in the case of a sale at a broker's board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which the Collateral, or portion thereof, will first be offered for sale at such board or exchange. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as the Collateral Agent may fix and state in the notice (if any) of such sale. At any such sale, the Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Collateral Agent may (in its sole and absolute discretion) determine. The Collateral Agent shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given. The Collateral Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case any sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by the Collateral Agent until the sale price is paid by the purchaser or purchasers thereof, but the Collateral Agent shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like notice. At any public (or, to the extent permitted by law, private) sale made pursuant to this Section, any Secured Party may bid for or purchase, free (to the extent permitted by law) from any right of redemption, stay, valuation or appraisal on the part of any Grantor (all said rights being also hereby waived and released to the extent permitted by law), the Collateral or any part thereof offered for sale and may make payment on account thereof by using any Reimbursement Obligation then due and payable to such Secured Party from any Grantor as a credit against the purchase price, and such Secured Party may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to any Grantor therefor. For purposes hereof a written agreement to purchase the Collateral or any portion thereof shall be treated as a sale thereof; the Collateral Agent shall be free to carry out such sale pursuant to such agreement and no Grantor shall be entitled to the return of the Collateral or any portion thereof subject thereto, notwithstanding the fact that after the Collateral Agent shall have entered into such an agreement all Events of Default shall have been remedied and the Reimbursement Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, the Collateral Agent may proceed by a suit or suits at law or in equity to foreclose this Agreement and to sell the Collateral or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver.</P>
<P>&#9;SECTION 6.02. <U>Application of Proceeds</U>. The Collateral Agent shall apply the proceeds of any collection or sale of the Collateral, as well as any Collateral consisting of cash, as follows:</P><DIR>
<DIR>

<P>FIRST, to the payment of all costs and reasonable expenses incurred by the Collateral Agent (in its capacity as such hereunder or under any other Reimbursement Document) in connection with such collection or sale or otherwise in connection with this Agreement or any of the Reimbursement Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Collateral Agent hereunder or under any other Reimbursement Document on behalf of any Grantor and any other costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Reimbursement Document;</P>
<P>SECOND, to the payment in full of the Reimbursement Obligations and the Revolving Credit Obligations in accordance with Section 5.04 of the Intercreditor Agreement (the amounts so applied to be distributed among the secured parties pro&nbsp;rata in accordance with the amounts of the Reimbursement Obligations and/or Revolving Credit Obligations owed to them on the date of any such distribution);</P>
<P>THIRD, to the payment in full of the Indenture Obligations outstanding; and</P>
<P>FOURTH, to the Grantors, their successors or assigns, or as a court of competent jurisdiction may otherwise direct.</P></DIR>
</DIR>

<P>&#9;The Collateral Agent shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Agreement. Upon any sale of the Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof.</P>
<P>&#9;SECTION 6.03. <U>Grant of License to Use Intellectual Property</U>. For the purpose of enabling the Collateral Agent to exercise rights and remedies under this Article at such time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies, each Grantor hereby grants to the Collateral Agent an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to the Grantors) to use, license or sub-license any of the Collateral consisting of Intellectual Property now owned or hereafter acquired by such Grantor, and wherever the same may be located, and including in such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer software and programs used for the compilation or printout thereof. The use of such license by the Collateral Agent shall be exercised, at the option of the Collateral Agent, upon the occurrence and during the continuation of an Event of Default; <U>provided</U> that any license, sub-license or other transaction entered into by the Collateral Agent in accordance herewith shall be binding upon the Grantors notwithstanding any subsequent cure of an Event of Default.</P>

<P>&#9;SECTION 7.04. <U>Survival of Agreement</U>. All covenants, agreements, representations and warranties made by any Grantor herein and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the Secured Parties and shall survive the making of the Guaranty by the Fund Guarantors, and the execution and delivery to the Fund Guarantors of any agreements, notes, instruments or documents evidencing such Guaranty, regardless of any investigation made by the Fund Guarantors or on their behalf, and shall continue in full force and effect until this Agreement shall terminate.</P>
<P>&#9;SECTION 7.05. <U>Binding Effect; Several Agreement</U>. This Agreement shall become effective as to any Grantor when a counterpart hereof executed on behalf of such Grantor shall have been delivered to the Collateral Agent and a counterpart hereof shall have been executed on behalf of the Collateral Agent, and thereafter shall be binding upon such Grantor and the Collateral Agent and their respective successors and assigns, and shall inure to the benefit of such Grantor, the Collateral Agent and the other Secured Parties and their respective successors and assigns, except that no Grantor shall have the right to assign or transfer its rights or obligations hereunder or any interest herein or in the Collateral (and any such assignment or transfer shall be void) except as expressly contemplated by this Agreement or the other Reimbursement Documents. This Agreement shall be construed as a separate agreement with respect to each Grantor and may be amended, modified, supplemented, waived or released with respect to any Grantor without the approval of any other Grantor and without affecting the obligations of any other Grantor hereunder.</P>
<P>&#9;SECTION 7.06. <U>Successors and Assigns</U>. Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the successors and assigns of such party; and all covenants, promises and agreements by or on behalf of any Grantor or the Collateral Agent that are contained in this Agreement shall bind and inure to the benefit of their respective successors and assigns.</P>
<P>&#9;SECTION 7.07. <U>Collateral Agent's Fees and Expenses; Indemnification</U>.

The rights and remedies of the Collateral Agent hereunder and of the Collateral Agent and the Fund Guarantors under the other Reimbursement Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provisions of this Agreement or any other Reimbursement Document or consent to any departure by any Grantor therefrom shall in any event be effective unless the same shall be permitted by paragraph&nbsp;(b) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.</P>
<P>&#9;SECTION 7.13 <U>Counterparts</U>. This Agreement may be executed in two or more counterparts, each of which shall constitute an original but all of which when taken together shall constitute but one contract (subject to Section&nbsp;7.05), and shall become effective as provided in Section&nbsp;7.05. Delivery of an executed signature page to this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof.</P>
<P>&#9;SECTION 7.14. <U>Headings</U>. Article and Section headings used herein are for the purpose of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.</P>
<P>&#9;SECTION 7.15. <U>Jurisdiction; Consent to Service of Process</U>. (a) Each Grantor hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Reimbursement Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each Grantor agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Collateral Agent or any Fund Guarantor may otherwise have to bring any action or proceeding relating to this Agreement or the other Reimbursement Documents against any Grantor or its properties in the courts of any jurisdiction.</P>
<P>&#9;(b) Each Grantor hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the other Reimbursement Documents in any New York State or Federal court. Each Grantor hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.</P>
<P>&#9;(c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section&nbsp;7.01. Nothing in this Agreement will affected the right of any party to this Agreement to serve process in any other manner permitted by law.</P>
<P>&#9;SECTION 7.16. <U>Termination</U>. This Agreement and the Security Interest shall terminate when all the Reimbursement Obligations have been indefeasibly paid in full and the Fund Guarantors have no further obligations under the Guaranty<FONT FACE="CG Times,Times New Roman">, </FONT>at which time the Collateral Agent shall execute and deliver to the Grantors, at the Grantors' expense, all UCC termination statements and similar documents which the Grantors shall reasonably request to evidence such termination. Any execution and delivery of termination statements or documents pursuant to this Section&nbsp;7.16 shall be without recourse to or warranty by the Collateral Agent. A Grantor shall automatically be released from its obligations hereunder and the Security Interest in the Collateral of such Grantor shall be automatically released in the event that such Grantor ceases to be a Subsidiary pursuant to a transaction permitted under the Reimbursement Documents, at which time the Collateral Agent shall execute and deliver to any Grantor, at such Grantor's expense, all documents that such Grantor shall reasonably request to evidence such release.</P>
<P>&#9;SECTION 7.17. <U>Additional Grantors</U>. Pursuant to Section 5.10 of the Reimbursement Agreement, each Subsidiary Reimbursement Party that was not in existence or not a Subsidiary Reimbursement Party on the date of the Reimbursement Agreement is required to enter into this Agreement as a Grantor upon becoming a Subsidiary Reimbursement Party. Upon execution and delivery by the Collateral Agent and a Subsidiary of an instrument in the form of Annex 3 hereto, such Subsidiary shall become a Grantor hereunder with the same force and effect as if originally named as a Grantor herein. The execution and delivery of any such instrument shall not require the consent of any Grantor hereunder. The rights and obligations of each Grantor hereunder shall remain in full force and effect notwithstanding the addition of any new Grantor as a party to this Agreement.</P>
<P>&#9;&#9;IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement as of the day and year first above written.</P>

<P>SUPPLEMENT NO. [ ] dated as of [&#9;], to the Amended and Restated Security Agreement dated as of December 21, 2001, among MEMC ELECTRONIC MATERIALS, INC., a Delaware corporation (the "<U>Borrower</U>"), each subsidiary of Borrower listed on Schedule I thereto (each such subsidiary individually a "<U>Subsidiary</U>" or a "<U>Guarantor</U>" and, collectively, the "<U>Subsidiaries</U>" or "<U>Guarantors</U>"; the Guarantors and the Borrower are referred to collectively herein as the "<U>Grantors</U>") and CITICORP USA, INC. as collateral agent (in such capacity, the "<U>Collateral Agent</U>") for the Secured Parties (as defined herein).</P>
<P>&nbsp;</P></DIR>
</DIR>
</DIR>
</DIR>

<P>&#9;A. Reference is made to (a) the Reimbursement Agreement dated as of December 21, 2001 (as amended, supplemented or otherwise modified from time to time) among the Borrower, the Fund Guarantors and CITICORP USA, INC., as collateral agent (in such capacity, the "<U>Collateral Agent</U>") and (b) the Amended and Restated Guarantee Agreement dated as of December 21, 2001 (as amended, supplemented or otherwise modified from time to time, the "<U>Amended and Restated Guarantee Agreement</U>"), among the Guarantors and the Collateral Agent.</P>
<P>&#9;B. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Amended and Restated Security Agreement and the Reimbursement Agreement.</P>
<P>&#9;C. The Grantors have entered into the Amended and Restated Security Agreement in order to induce the Fund Guarantors to guarantee the Borrower's obligations under the Revolving Credit Agreement. Pursuant to Section 5.10 of the Reimbursement Agreement, each Subsidiary Reimbursement Party that was not in existence or not a Subsidiary Reimbursement Party on the date of the Reimbursement Agreement is required to enter into this Agreement as a Grantor upon becoming a Subsidiary Reimbursement Party. Section&nbsp;7.17 of the Amended and Restated Security Agreement provides that such Subsidiaries may become Grantors under the Amended and Restated Security Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary (the "<U>New Grantor</U>") is executing this Supplement in accordance with the requirements of the Reimbursement Agreement to become a Grantor under the Amended and Restated Security Agreement in order to induce the Fund Guarantors to make additional guarantees and as consideration for guarantees previously made.</P>
<P>&#9;Accordingly, the Collateral Agent and the New Grantor agree as follows:</P>
<P>&#9;SECTION 1. In accordance with Section&nbsp;7.17 of the Amended and Restated Security Agreement, the New Grantor by its signature below becomes a Grantor under the Amended and Restated Security Agreement with the same force and effect as if originally named therein as a Grantor and the New Grantor hereby (a) agrees to all the terms and provisions of the Amended and Restated Security Agreement applicable to it as a Grantor thereunder and (b)&nbsp;represents and warrants that the representations and warranties made by it as a Grantor thereunder are true and correct on and as of the date hereof except to the extent a representation and warranty expressly relates solely to a specific date in which case such representation and warranty shall be true and correct on such date. In furtherance of the foregoing, the New Grantor, as security for the payment and performance in full of the Reimbursement Obligations (as defined in the Amended and Restated Security Agreement), does hereby create and grant to the Collateral Agent, its successors and assigns, for the benefit of the Secured Parties, their successors and assigns, a security interest in and lien on all of the New Grantor's right, title and interest in and to the Collateral of the New Grantor. Each reference to a "Grantor" in the Amended and Restated Security Agreement shall be deemed to include the New Grantor. The Amended and Restated Security Agreement is hereby incorporated herein by reference.</P>
<P>&#9;SECTION 2. The New Grantor represents and warrants to the Collateral Agent and the other Secured Parties 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.</P>
<P>&#9;SECTION 3. This Supplement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Supplement shall become effective when the Collateral Agent shall have received counterparts of this Supplement that, when taken together, bear the signatures of the New Grantor and the Collateral Agent. Delivery of an executed signature page to this Supplement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Supplement.</P>
<P>&#9;SECTION&nbsp;4. The New Grantor hereby represents and warrants that (a)&nbsp;set forth on Schedule&nbsp;I attached hereto is a true and correct statement of the exact corporate name and jurisdiction of organization of the New Grantor and a true and correct schedule of the location of any and all Collateral of the New Grantor and (b)&nbsp;set forth under its signature hereto, is the true and correct location of the chief executive office of the New Grantor.</P>
<P>&#9;SECTION 5. Except as expressly supplemented hereby, the Amended and Restated Security Agreement shall remain in full force and effect.</P>
<P>&#9;<B>SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW&nbsp;YORK.</P>
</B><P>&#9;SECTION 7. In case any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and in the Amended and Restated Security Agreement shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.</P>
<P>&#9;SECTION 8. All communications and notices hereunder shall be in writing and given as provided in Section&nbsp;7.01 of the Amended and Restated Security Agreement. All communications and notices hereunder to the New Grantor shall be given to it at the address set forth under its signature below, with a copy to the Borrower.</P>
<P>&#9;SECTION 9. The New Grantor agrees to reimburse the Collateral 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 Collateral Agent.</P>
<P>&nbsp;</P>
<P>&nbsp;</P>
<P>&nbsp;</P>
<P>&#9;IN WITNESS WHEREOF, the New Grantor and the Collateral Agent have duly executed this Supplement to the Amended and Restated Security Agreement as of the day and year first above written.</P>
