(a) Such Grantor is duly organized, validly existing and in good standing under the laws of the jurisdiction identified as its jurisdiction of organization in its Perfection Certificate.

(b) With respect to each Grantor, Schedule 1 lists all Equity Interests owned by such Grantor as of the date hereof. Such Grantor holds all such Equity Interests directly (i.e., not through a Subsidiary, a Securities Intermediary or any other Person).

(c)  With respect to each Grantor, Schedule 2 lists, as of the date hereof, (i) all Securities owned by such Grantor (except Securities evidencing Equity Interests) and (ii) all Securities Accounts to which Financial Assets are credited in respect of which such Grantor owns Security Entitlements.

(d) Grantor owns no Commodity Account in respect of which such Grantor is the Commodity Customer.

(e) All Pledged Equity Interests owned by such Grantor are owned by it free and clear of any Lien other than (i) the Transaction Liens and (ii) any Permitted Liens. All shares of capital stock included in such Pledged Equity Interests (including shares of capital stock in respect of which such Grantor owns a Security Entitlement) have been duly authorized and validly issued and are fully paid and non-assessable. None of such Pledged Equity Interests is subject to any

11

option to purchase or similar right of any Person. Such Grantor is not and will not become a party to or otherwise bound by any agreement which restricts in any manner the rights of any present or future holder of any Pledged Equity Interest with respect thereto.

(f) Such Grantor has good and marketable title to all its Collateral (subject to exceptions that are, in the aggregate, not material), free and clear of any Lien other than Permitted Liens.

(g) Such Grantor has not performed any acts that might prevent the Secured Party from enforcing any of the provisions of the Security Documents or that would limit the Secured Party in any such enforcement. No financing statement, security agreement, mortgage or similar or equivalent document or instrument covering all or part of the Collateral owned by such Grantor is on file or of record in any jurisdiction in which such filing or recording would be effective to perfect or record a Lien on such Collateral, except financing statements, mortgages or other similar or equivalent documents with respect to Permitted Liens. After the date hereof, no Collateral owned by such Grantor will be in the possession or under the Control of any other Person having a claim thereto or security interest therein.

(h) The Transaction Liens on all Collateral owned by such Grantor (i) have been validly created, (ii) will attach to each item of such Collateral on the date hereof (or, if such Grantor first obtains rights thereto on a later date, on such later date) and (iii) when so attached, will secure all the Secured Obligations.

(i) Such Grantor has delivered a Perfection Certificate to the Secured Party. With respect to each Grantor, information set forth therein is correct and complete as of the date hereof. Within 60 days from the date hereof, such Grantor will furnish to the Secured Party a file search report from each UCC filing office listed in its Perfection Certificate, showing the filing made at such filing office to perfect the Transaction Liens on its Collateral.

(j) Upon (i) the filing of a UCC financing statement in proper and appropriate form in the relevant filing office with respect to any Grantor, to the extent that the security interest granted hereunder in the Collateral of such Grantor may be perfected by filing a UCC financing statement, and (ii) the taking of possession in the case of Collateral with respect to which a security interest may be perfected through possession, such security interest will constitute a perfected security interest in such Collateral. When, in addition to the filing of such UCC financing statements, the applicable Intellectual Property Filings have been made with respect to such Grantor’s Recordable Intellectual Property (including any future filings required pursuant to Sections 4(a) and 5(a)), the Transaction Liens will constitute perfected security interests in all right, title and interest of such

12

Grantor in its Recordable Intellectual Property to the extent that security interests therein may be perfected by such filings, prior to all Liens and rights of others therein except Permitted Liens. Except for (i) the filing of such UCC financing statements and (ii) such Intellectual Property Filings, no registration, recordation or filing with any governmental body, agency or official is required in connection with the execution or delivery of the Security Documents or is necessary for the validity or enforceability thereof or for the perfection or due recordation of the Transaction Liens or for the enforcement of the Transaction Liens. Upon execution and delivery of an Account Control Agreement in respect of each Collateral Account, the security interest of the Secured Party with respect to such Collateral Account shall be perfected by Control.

(k) Such Grantor has taken, and will continue to take, all actions necessary under the UCC to perfect its interest in any Accounts or Chattel Paper purchased or otherwise acquired by it, as against its assignors and creditors of its assignors.

SECTION 4. Further Assurances; General Covenants. Each Grantor covenants as follows:

(a) Such Grantor will, from time to time, at such Grantor’s expense, execute, deliver, file and record any statement, assignment, instrument, document, agreement or other paper and take any other action (including any Intellectual Property Filing) that from time to time may be necessary or desirable, or that the Secured Party may reasonably request, in order to:

(i) create, preserve, perfect, confirm or validate the Transaction Liens on such Grantor’s Collateral;

(ii) in the case of Pledged Deposit Accounts and Pledged Investment Property, cause the Secured Party to have Control thereof;

(iii) enable the Secured Party to obtain the full benefits of the Security Documents; or

(iv) enable the Secured Party to exercise and enforce any of its rights, powers and remedies with respect to any of such Grantor’s Collateral.

Such Grantor authorizes the Secured Party to execute and file such financing statements or continuation statements in such jurisdictions with such descriptions of collateral (including “all assets” or “all personal property” or other words to that effect) and other information set forth therein as the Secured Party may reasonably deem necessary or desirable for the purposes set forth in the preceding sentence. Each Grantor also ratifies its authorization for the Secured Party to file

13

in any such jurisdiction any initial financing statements or amendments thereto if filed prior to the date hereof. The Secured Party is further authorized to file with the United States Patent and Trademark Office or United States Copyright Office (or any successor office or any similar office in any other country) such documents as may reasonably be necessary or advisable for the purpose of perfecting, confirming, continuing, enforcing or protecting the security interests granted by each Grantor, without the signature of any Grantor, and naming any Grantor or the Grantors as debtors and the Secured Party as secured party. The relevant Grantor will pay the costs of, or incidental to, any Intellectual Property Filings and any recording or filing of any financing or continuation statements or other documents recorded or filed pursuant hereto.

(b) Such Grantor will not (i) change its name or organizational form or structure, (ii) change its location (determined as provided in UCC Section 9-307) or (iii) become bound, as provided in UCC Section 9-203(d) or otherwise, by a security agreement entered into by another Person, unless it shall have given the Secured Party prior notice thereof and delivered an Opinion of Counsel with respect thereto in accordance with Section 4(c).

(c) At least 30 days before it takes any action contemplated by Section 4(b), such Grantor will, at its expense, cause to be delivered to the Secured Party an Opinion of Counsel, in form and substance reasonably satisfactory to Party B, to the effect that (i) all financing statements and amendments or supplements thereto, continuation statements and other documents required to be filed or recorded in order to perfect and protect the Transaction Liens against all creditors of and purchasers from such Grantor after it takes such action (except any continuation statements specified in such Opinion of Counsel that are to be filed more than six months after the date thereof) have been filed or recorded in each office necessary for such purpose, (ii) all fees and taxes, if any, payable in connection with such filings or recordations have been paid in full and (iii) except as otherwise agreed by the Secured Party, such action will not adversely affect the perfection or priority of the Transaction Lien on any Collateral to be owned by such Grantor after it takes such action or the accuracy of such Grantor’s representations and warranties herein relating to such Collateral.

(d) If any of its Collateral is in the possession or control of a warehouseman, bailee or agent at any time, such Grantor will (i) notify such warehouseman, bailee or agent of the relevant Transaction Liens, (ii) instruct such warehouseman, bailee or agent to hold all such Collateral for the Secured Party’s account subject to the Secured Party’s instructions (which shall permit such Collateral to be removed by such Grantor in the ordinary course of business until the Secured Party notifies such warehouseman, bailee or agent that an Event of Default has occurred and is continuing), (iii) cause such warehouseman, bailee or agent to Authenticate a Record acknowledging that it holds possession of such Collateral for the Secured Party’s benefit and (iv) make such Authenticated Record available to the Secured Party.

14

(e) Such Grantor will not sell, lease, exchange, assign or otherwise dispose of, or grant any option with respect to, any of its Collateral; provided that such Grantor may do any of the foregoing unless (i) doing so would violate a provision of this Agreement or the Loan Contracts or (ii) an Event of Default shall have occurred and be continuing and either (A) the Secured Party shall have notified such Grantor that its right to do so is terminated, suspended or otherwise limited or (B) the maturity of any or all of any Secured Obligations shall have been accelerated. Concurrently with any sale, lease or other disposition (except a sale or disposition to another Grantor or a lease) permitted by the foregoing proviso, the Transaction Liens on the assets sold or disposed of (but not in any Proceeds arising from such sale or disposition) will cease immediately without any action by the Secured Party. The Secured Party will, at Party A’s expense, execute and deliver to the relevant Grantor such documents as such Grantor shall reasonably request to evidence the fact that any asset so sold or disposed of is no longer subject to a Transaction Lien.

(f) Such Grantor will, promptly upon request, provide to the Secured Party all information and evidence concerning such Grantor’s Collateral that the Secured Party may reasonably request from time to time to enable it to enforce the provisions of the Security Documents.

SECTION 5. Recordable Intellectual Property. Each Grantor covenants as follows:

(a) Promptly (and in any event within 20 business days) upon request by Party B, each Grantor will promptly sign and deliver to the Secured Party Intellectual Property Security Agreements with respect to all Recordable Intellectual Property then owned by it. Within 30 days after each December 31 thereafter, it will sign and deliver to the Secured Party an appropriate Intellectual Property Security Agreement covering any Recordable Intellectual Property owned by it on such December 31 that is not covered by any previous Intellectual Property Security Agreement so signed and delivered by it. In each case, it will promptly make all Intellectual Property Filings necessary to record the Transaction Liens on such Recordable Intellectual Property.

(b) Upon the occurrence and during the continuance of an Event of Default, each Grantor shall use its best efforts to obtain all requisite consents or approvals by the licensor of each Copyright License, Patent License or Trademark License under which such Grantor is a licensee to effect the assignment of all such Grantor’s right, title and interest thereunder to Party B for the benefit of the Secured Party.

15

SECTION 6. Investment Property. Each Grantor represents, warrants and covenants as follows:

(a) Certificated Securities. On the date hereof, each Grantor will deliver to the Secured Party as Collateral hereunder all certificates representing Pledged Certificated Securities then owned by such Grantor. Thereafter, whenever such Grantor acquires any other certificate representing a Pledged Certificated Security, such Grantor will immediately deliver such certificate to the Secured Party as Collateral hereunder. The provisions of this subsection are subject to the limitation in Section 6(g) in the case of voting Equity Interests in a Foreign Subsidiary.

(b) Uncertificated Securities. Upon request by Party B, each Grantor will promptly (and in any event within 20 business days) enter into (and cause the relevant issuer to enter into) an Issuer Control Agreement in respect of each Pledged Uncertificated Security then owned by such Grantor and deliver such Issuer Control Agreement to the Secured Party (which shall enter into the same). Thereafter, whenever such Grantor acquires any other Pledged Uncertificated Security, such Grantor will enter into (and cause the relevant issuer to enter into) an Issuer Control Agreement in respect of such Pledged Uncertificated Security and deliver such Issuer Control Agreement to the Secured Party (which shall enter into the same). The provisions of this subsection are subject to the limitation in Section 6(g) in the case of voting Equity Interests in a Foreign Subsidiary.

(c) Security Entitlements. Upon request by Party B, each Grantor will, with respect to each Security Entitlement then owned by it, promptly enter into (and cause the relevant Securities Intermediary to enter into) a Securities Account Control Agreement in respect of such Security Entitlement and the Securities Account to which the underlying Financial Asset is credited and will deliver such Securities Account Control Agreement to the Secured Party (which shall enter into the same). Thereafter, whenever such Grantor acquires any other Security Entitlement, such Grantor will, as promptly as practicable, cause the underlying Financial Asset to be credited to a Controlled Securities Account.

(d) Agreement as to Applicable Jurisdiction. In respect of all Security Entitlements owned by such Grantor, and all Securities Accounts to which the related Financial Assets are credited, the Securities Intermediary’s jurisdiction (determined as provided in UCC Section 8-110(e)) will at all times be located in the United States.

(e) Delivery of Pledged Certificates. All Pledged Certificates, when delivered to the Secured Party, will be in suitable form for transfer by delivery, or accompanied by duly executed instruments of transfer or assignment in blank, with signatures appropriately guaranteed, all in form and substance reasonably satisfactory to Party B.

16

(f) Communications. Each Grantor will promptly give to the Secured Party copies of any notices and other communications received by it with respect to (i) Pledged Securities registered in the name of such Grantor or its nominee and (ii) Pledged Security Entitlements as to which such Grantor is the Entitlement Holder.

(g) Foreign Subsidiaries. A Grantor will not be obligated to comply with the provisions of this Section at any time with respect to any voting Equity Interest in a Foreign Subsidiary if and to the extent (but only to the extent) that such voting Equity Interest is excluded from the Transaction Liens at such time pursuant to clause (B) of the proviso at the end of Section 2.

(h) Certification of Limited Liability Company and Partnership Interests. Any limited liability company and any partnership controlled by any Grantor shall either (i) not include in its operative documents any provision that any Equity Interests in such limited liability company or such partnership be a “security” as defined under Article 8 of the Uniform Commercial Code, or (ii) certificate any Equity Interests in any such limited liability company or such partnership. To the extent an interest in any limited liability company or partnership controlled by any Grantor and pledged hereunder is certificated or becomes certificated, each such certificate shall be delivered to the Secured Party pursuant to Section 6(a) and such Grantor shall fulfill all other requirements under Section 6 applicable in respect thereof.

SECTION 7. Deposit Accounts. Each Grantor represents, warrants and covenants as follows:

(a) Promptly (and in any event within 20 business days) upon the request of Party B, each Grantor shall, with respect to each Deposit Account and Commodity Account then maintained by it, enter into (and cause the relevant Depositary Bank and Commodity Intermediary to enter into) a Deposit Account Control Agreement and Commodity Account Control Agreement, as applicable, in form and substance reasonably satisfactory to Party B in respect of such Deposit Account or Commodity Account, as applicable, and will deliver such control agreement to the Secured Party (which shall enter into the same). Thereafter, all cash owned by such Grantor will be deposited, upon or promptly after the receipt thereof, in one or more Controlled Deposit Accounts. Whenever any Grantor establishes any other Deposit Account or Commodity Account, such Grantor shall promptly (and in any event within 20 business days) upon the Party B’s request, cause the relevant Depositary Bank and Commodity Intermediary to enter into a Deposit Account Control Agreement and Commodity Account Control Agreement, as applicable, in form and substance reasonably satisfactory to Party B over such Deposit Account or Commodity Account for the benefit of the Secured Party.

17

(b) In respect of each Controlled Deposit Account, the Depositary Bank’s jurisdiction (determined as provided in UCC Section 9-304) will at all times be a jurisdiction in which Article 9 of the Uniform Commercial Code is in effect.

(c) The Secured Party agrees that it will not (i) originate any instructions directing disposition of funds in any Deposit Account or any other instruction in respect of the Deposit Accounts or (ii) issue a Notice of Control or Notice of Exclusive Control (as defined in the relevant Deposit Account Control Agreement) in respect of any Deposit Account unless, in either case, an Event of Default shall have occurred and be continuing, and in each case the Secured Party shall promptly provide a copy to Party A of such instructions or notice.

(d) So long as the Secured Party has Control of a Controlled Deposit Account, the Transaction Lien on such Controlled Deposit Account will be perfected, subject to no prior Liens or rights of others (except CCB’s right to deduct its normal operating charges and any uncollected funds previously credited thereto).

SECTION 8. Commercial Tort Claims. Each Grantor represents, warrants and covenants that Schedule 3 accurately describes, with the specificity required to satisfy Official Comment 5 to UCC Section 9-108, each Material Commercial Tort Claim with respect to which such Grantor is the claimant as of the date hereof.

SECTION 9. Transfer of Record Ownership. At any time when an Event of Default shall have occurred and be continuing, the Secured Party may (and to the extent that action by it is required, the relevant Grantor, if directed to do so by the Secured Party, will as promptly as practicable) cause each of the Pledged Securities (or any portion thereof specified in such direction) to be transferred of record into the name of the Secured Party or its nominee. Each Grantor will take any and all actions reasonably requested by the Secured Party to facilitate compliance with this Section. If the provisions of this Section are implemented, Section 6(b) shall not thereafter apply to any Pledged Security that is registered in the name of the Secured Party or its nominee. The Secured Party will promptly give to the relevant Grantor copies of any notices and other communications received by the Secured Party with respect to Pledged Securities registered in the name of the Secured Party or its nominee.

18

SECTION 10. Right to Vote Securities. (a) Unless an Event of Default shall have occurred and be continuing, each Grantor will have the right, from time to time, to vote and to give consents, ratifications and waivers with respect to any Pledged Security owned by it and the Financial Asset underlying any Pledged Security Entitlement owned by it, and the Secured Party will, upon receiving a written request from such Grantor, deliver to such Grantor or as specified in such request such proxies, powers of attorney, consents, ratifications and waivers in respect of any such Pledged Security that is registered in the name of the Secured Party or its nominee or any such Pledged Security Entitlement as to which the Secured Party or its nominee is the Entitlement Holder, in each case as shall be specified in such request and be in form and substance reasonably satisfactory to Party B.

(b) If an Event of Default shall have occurred and be continuing, Party B on behalf of the Secured Party will have the exclusive right to the extent permitted by law to vote, to give consents, ratifications and waivers and to take any other action with respect to the Pledged Investment Property, the other Pledged Equity Interests and the Financial Assets underlying the Pledged Security Entitlements, with the same force and effect as if the Secured Party were the absolute and sole owner thereof, and each Grantor will take all such action as Party B may reasonably request from time to time to give effect to such right.

SECTION 11. Certain Cash Distributions. At any time after Party B shall have requested that Deposit Account Control Agreements be executed in respect of any Deposit Accounts of any Grantor pursuant to Section 7(a) above, Cash Distributions with respect to any Pledged Equity Interest or Pledged Debt of such Grantor that is not held in a Collateral Account (whether held in the name of a Grantor or in the name of Party B or its nominee) shall be deposited, promptly upon receipt thereof, in a Controlled Deposit Account of the relevant Grantor.

SECTION 12. Remedies upon Event of Default. (a) If an Event of Default shall have occurred and be continuing, the Secured Party may exercise any or all of the remedies available to it under the Security Documents.

(b) Without limiting the generality of the foregoing, if an Event of Default shall have occurred and be continuing, the Secured Party may exercise all the rights of a secured party under the UCC (whether or not in effect in the jurisdiction where such rights are exercised) with respect to any Collateral and, in addition, the Secured Party may, without being required to give any notice, except as herein provided or as may be required by mandatory provisions of law, sell or otherwise dispose of the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or at any of the Secured Party’s offices or elsewhere, for cash, on credit or for future delivery, at such time or times and at such price or prices and upon such other terms as the Secured Party may deem commercially reasonable, irrespective of the impact of any such sales on the market price of the Collateral. To the maximum extent permitted by

19

applicable law, the Secured Party may be the purchaser of any or all of the Collateral at any such sale and shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any such public sale, to use and apply all of any part of the Secured Obligations as a credit on account of the purchase price of any Collateral payable at such sale. Upon any sale of Collateral by the Secured Party (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Secured Party 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 to the Secured Party or such officer or be answerable in any way for the misapplication thereof. Each 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 or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Secured Party shall not be obliged to make any sale of Collateral regardless of notice of sale having been given. The Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the maximum extent permitted by law, each Grantor hereby waives any claim against the Secured Party arising because the price at which any Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if the Secured Party accepts the first offer received and does not offer such Collateral to more than one offeree. The Secured Party may disclaim any warranty, as to title or as to any other matter, in connection with such sale or other disposition, and its doing so shall not be considered adversely to affect the commercial reasonableness of such sale or other disposition.

(c) If the Secured Party sells any of the Collateral upon credit, the Grantors will be credited only with payment actually made by the purchaser, received by the Secured Party and applied in accordance with Section 13 hereof. In the event the purchaser fails to pay for the Collateral, the Secured Party may resell the same, subject to the same rights and duties set forth herein.

(d) Notice of any such sale or other disposition shall be given to the relevant Grantor(s) as (and if) required by Section 15.

(e) For the purpose of enabling the Secured Party to exercise rights and remedies under this Agreement at such time as the Secured Party shall be lawfully entitled to exercise such rights and remedies, each Grantor hereby grants to the Secured Party an irrevocable license (exercisable without payment of royalty or other compensation to the Grantors), to use, license or sublicense any

20

of the Collateral consisting of Intellectual Property now owned or hereafter acquired by such Grantor, and including in such license 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 Secured Party may be exercised only upon the occurrence and during the continuation of an Event of Default; provided, however, that any license, sublicense or other transaction entered into by the Secured Party in accordance herewith shall be binding upon each Grantor notwithstanding any subsequent cure of an Event of Default.

SECTION 13. Application of Proceeds. (a) If an Event of Default shall have occurred and be continuing, the Secured Party may apply (i) any cash held in the Collateral Accounts and (ii) the proceeds of any sale or other disposition of all or any part of the Collateral, in the following order of priorities:

first, to pay the expenses of such sale or other disposition, including reasonable compensation to agents of and counsel for the Secured Party, and all expenses, liabilities and advances incurred or made by the Secured Party in connection with the Security Documents, and any other amounts then due and payable to the Secured Party pursuant to Section 14;

second, to pay all Secured Obligations ratably ; and

finally, if (and only if) the Release Condition, have been satisfied, to pay to the relevant Grantor, or as a court of competent jurisdiction may direct, any surplus then remaining from the proceeds of the Collateral owned by it;

provided that Collateral owned by a subsidiary and any proceeds thereof shall be applied pursuant to the foregoing clauses first and second only to the extent permitted by the limitations set forth in Section 4 of the Parent Indemnity and Subsidiary Guarantee Letter Agreement.

SECTION 14. Fees and Expenses; Indemnification. (a) Each Grantor agrees, jointly and severally, to forthwith upon demand pay to the Secured Party:

(i) the amount of any taxes that the Secured Party may have been required to pay by reason of the Transaction Liens or to free any Collateral from any other Lien thereon;

(ii) the amount of any and all reasonable out-of-pocket expenses, including transfer taxes and reasonable fees and expenses of counsel and other experts, that the Secured Party may incur in connection with (x) the administration or enforcement of the Security Documents,

21

including such expenses as are incurred to preserve the value of the Collateral or the validity, perfection, rank or value of any Transaction Lien, (y) the collection, sale or other disposition of any Collateral or (z) the exercise by the Secured Party of any of its rights or powers under the Security Documents;

(iii) the amount of any fees that any Grantor shall have agreed in writing to pay to the Secured Party and that shall have become due and payable in accordance with such written agreement; and

(iv) the amount required to indemnify the Secured Party for, or hold it harmless and defend it against, any loss, liability or expense (including the reasonable fees and expenses of its counsel and any experts or agents appointed by it hereunder) incurred or suffered by the Secured Party in connection with the Security Documents, except to the extent that such loss, liability or expense arises from the Secured Party’s gross negligence or willful misconduct or a breach of any duty that the Secured Party has under this Agreement (after giving effect to Section 17).

Any such amount not paid to the Secured Party on demand will bear interest for each day thereafter until paid at a rate per annum equal to the sum of 2% plus the rate applicable to the Loans.

(b) If any transfer tax, documentary stamp tax or other tax is payable in connection with any transfer or other transaction provided for in the Security Documents, Party A will pay such tax and provide any required tax stamps to the Secured Party or as otherwise required by law.

(c) The Grantors shall, jointly and severally, indemnify each of the Secured Parties and their respective affiliates and the respective directors, officers, agents and employees of the foregoing (each an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all liabilities, losses, damages, costs and expenses of any kind arising out of, or in connection with the Loan Contracts or any Security Document, except to the extent that such loss, liability or expense arises from such Indemnitee’s gross negligence or willful misconduct.

SECTION 15. Authority to Administer Collateral. Each Grantor irrevocably appoints the Secured Party its true and lawful attorney, with full power of substitution, in the name of such Grantor, for the sole use and benefit of the Secured Party, but at Party A’s expense, to the extent permitted by law to exercise, at any time and from time to time while an Event of Default shall have occurred and be continuing, all or any of the following powers with respect to all or any of such Grantor’s Collateral:

22

(a) to demand, xxx for, collect, receive and give acquittance for any and all monies due or to become due upon or by virtue thereof,

(b) to settle, compromise, compound, prosecute or defend any action or proceeding with respect thereto,

(c) to sell, lease, license or otherwise dispose of the same or the proceeds or avails thereof, as fully and effectually as if the Secured Party were the absolute owner thereof, and

(d) to extend the time of payment of any or all thereof and to make any allowance or other adjustment with reference thereto;

provided that, except in the case of Collateral that is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Secured Party will give the relevant Grantor at least ten days’ prior written notice of the time and place of any public sale thereof or the time after which any private sale or other intended disposition thereof will be made. Any such notice shall (i) contain the information specified in UCC Section 9-613, (ii) be Authenticated and (iii) be sent to the parties required to be notified pursuant to UCC Section 9-611(c); provided that, if the Secured Party fails to comply with this sentence in any respect, its liability for such failure shall be limited to the liability (if any) imposed on it as a matter of law under the UCC.

SECTION 16.  [reserved].

SECTION 17. Limitation on Duty in Respect of Collateral. Beyond the exercise of reasonable care in the custody and preservation thereof, the Secured Party will have no duty as to any Collateral in its possession or control or in the possession or control of any sub-agent or bailee or any income therefrom or as to the preservation of rights against prior parties or any other rights pertaining thereto. The Secured Party will be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession or control if such Collateral is accorded treatment substantially equal to that which it accords its own property, and will not be liable or responsible for any loss or damage to any Collateral, or for any diminution in the value thereof, by reason of any act or omission of any sub-agent or bailee selected by the Secured Party in good faith, except to the extent that such liability arises from the Secured Party’s gross negligence or willful misconduct.

SECTION 18.  Termination of Transaction Liens; Release of Collateral.

(a) The Transaction Liens granted by each Grantor shall terminate when all the Release Condition is satisfied.

23

(b) At any time before the Transaction Liens granted by each Grantor shall terminate, Party B may in its sole discretion, on behalf of the Secured Party, at the written request of the relevant Grantor, release any Collateral.

(c) Upon any termination of a Transaction Lien or release of Collateral, the Secured Party will, at the expense of the relevant Grantor, execute and deliver to such Grantor such documents as such Grantor shall reasonably request to evidence the termination of such Transaction Lien or the release of such Collateral, as the case may be.

SECTION 19. Notices. Each notice, request or other communication given to any party hereunder shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by telecopier as follows:

SECTION 20. No Implied Waivers; Remedies Not Exclusive. No failure by the Secured Party to exercise, and no delay in exercising and no course of dealing with respect to, any right or remedy under any Security Document shall operate as a waiver thereof; nor shall any single or partial exercise by the Secured Party of any right or remedy under in connection with any of the Secured Obligations preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies specified in connection with the Secured Obligations are cumulative and are not exclusive of any other rights or remedies provided by law.

SECTION 21. Successors and Assigns. This Agreement is for the benefit of the Secured Party. If all or any part of the Secured Party’s interest in any Secured Obligation is assigned or otherwise transferred, the transferor’s rights hereunder, to the extent applicable to the obligation so transferred, shall be

24

automatically transferred with such obligation. This Agreement shall be binding on the Grantors and their respective successors and assigns; provided that no Grantor may assign or otherwise transfer its obligations hereunder without the express written consent of Party B and any purported assignment in violation of this provision shall be null and void.

SECTION 22. Amendments and Waivers. Neither this Agreement nor any provision hereof may be waived, amended, modified or terminated except pursuant to an agreement or agreements in writing entered into by the Secured Party. No such waiver, amendment or modification shall be binding upon any Grantor, except with its written consent.

SECTION 23. Choice of Law. This Agreement shall be construed in accordance with and governed by the laws of the State of New York, except as otherwise required by mandatory provisions of law and except to the extent that remedies provided by the laws of any jurisdiction other than the State of New York are governed by the laws of such jurisdiction.

Flood insurance in an amount at least equal to the lesser of (A) the principal balance of the Entrustment Loan Contract, or (B) the maximum limit of coverage available for the Property under the National Flood Insurance Act of 1968, The Flood Disaster Protection Act of 1973 or the National Flood Insurance Reform Act of 1994, as each may be amended, or any successor law (the “Flood Acts”), if any portion of the Improvements is now or at any time in the future located within an area identified by the Secretary of Housing and Urban Development or any successor thereto as an area having special flood hazards pursuant to the Flood Acts.

(e) Other Insurance. Such other insurance with respect to the Property against loss or damage of the kinds from time to time customarily insured against and in such amounts as are generally available at commercially reasonable premiums and are generally required by institutional lenders for properties comparable to the Property.

Best Company, Inc. (each such insurer shall be referred to below as a “Qualified Insurer”). All insurers providing insurance required by this Deed of Trust shall be authorized to issue insurance in the state in which the Property is located. The Policy referred to in Paragraph (b) above shall name Beneficiary as an additional named insured and the Policy referred to in Paragraphs (a), (c), (d), and (e) above shall provide that all proceeds be payable to Beneficiary as set forth in this Deed of Trust. The Policies referred to in Paragraphs (a), (d), and (e) shall also contain: (i) a standard “non-contributory mortgagee” endorsement or its equivalent (such as the Beneficiary’s Loss Payable endorsement 438 BFU, in long form) relating, inter alia, to recovery by Beneficiary notwithstanding the negligent or willful acts or omission of Grantor; (ii) to the extent available at commercially reasonable rates, a waiver of subrogation endorsement as to Beneficiary; and (iii) an endorsement providing for a deductible per loss of an amount not more than that which is customarily maintained by prudent owners of similar properties in the general vicinity of the Property, but in no event in excess of an amount approved by Beneficiary. All Policies described in Subsection 2.11.1 shall contain (i) a provision that such policies shall not be canceled or terminated, nor shall they expire, without at least thirty (30) days’ prior written notice to Beneficiary in each instance; and (ii) include effective waivers by the insurer of all claims for Insurance Premiums (defined below) against any loss payees, additional insureds and

10

named insureds (other than Grantor). Certificates of insurance with respect to all renewal and replacement Policies shall be delivered to Beneficiary not less than thirty (30) days prior to the expiration date of any of the Policies required to be maintained hereunder which certificates shall bear notations evidencing payment of applicable premiums (the “Insurance Premiums”). Originals or certificates of such replacement Policies shall be delivered to Beneficiary promptly after Grantor’s receipt thereof but in any case within thirty (30) days after the effective date thereof. If Grantor fails to maintain and deliver to Beneficiary the original Policies or certificates of insurance required by this Deed of Trust, Beneficiary may procure such insurance at Grantor’s sole cost and expense.

2.11.3 Grantor shall comply with all insurance requirements and shall not bring or keep or permit to be brought or kept any article upon any of the Property or cause or permit any condition to exist thereon that would be prohibited by an insurance requirement, or would invalidate the insurance coverage required hereunder to be maintained by Grantor on or with respect to any part of the Property pursuant to this Section.

2.11.4 If the Property shall be damaged or destroyed, in whole or in part, by fire or other casualty, Grantor shall give prompt notice of such damage to Beneficiary and provided that Grantor shall have received the Net Proceeds (defined below), Grantor shall promptly commence and diligently prosecute the completion of the repair and restoration of the property as nearly as possible to the condition the Property was in immediately prior to such fire or other casualty, with such alterations as may be approved by Beneficiary (the “Restoration”) and otherwise in accordance with Section 2.13 of this Deed of Trust.

2.11.5 The insurance coverage required under Subsection 2.11.1 may be effected under a blanket policy or policies covering the Property and other properties and assets not constituting a part of the security hereunder; provided that any such blanket policy shall specify, except in the case of public liability insurance, the portion of the total coverage of such policy that is allocated to the Property, and any sublimit in such blanket policy applicable to the Property, and shall in any case comply in all other respects with the requirements of this Section.

2.11.6 Grantor waives any and all right to claim or recover against Beneficiary, its officers, employees, agents and representatives, by way of subrogation or otherwise, for any loss sustained by Grantor, or any loss or damage to the Property, Grantor’s property or the property of others under Grantor’s control from any cause insured against or required to be insured against by the provisions of this Deed of Trust.

2.12 Condemnation. Grantor shall promptly give Beneficiary notice of the actual or threatened commencement of any condemnation or eminent domain proceeding and shall deliver to Beneficiary copies of any and all papers served in connection with such proceedings. Beneficiary may participate in any such proceedings to the extent permitted by law. Upon an Event of Default, Grantor shall deliver to Beneficiary all instruments requested by it to permit such participation. Grantor shall, at its expense, diligently prosecute any such proceedings, and shall consult with Beneficiary, its attorneys and experts, and cooperate with them in the carrying on or defense of any such proceedings. Notwithstanding any taking by any public or quasi-

11

public authority through eminent domain or otherwise (including, but not limited to any transfer made in lieu of or in anticipation of the exercise of such taking), Grantor shall continue to pay the Secured Obligations at the time and in the manner provided for its payment in the Parent Indemnity and Subsidiary Guarantee Letter Agreement, the Supply Agreements and in this Deed of Trust and the Secured Obligations shall not be reduced until any award or payment therefor shall have been actually received and applied by Beneficiary, after the deduction of expenses of collection, to the reduction or discharge of such obligations. Beneficiary shall not be limited to the interest paid on the award by the condemning authority but shall be entitled to receive out of the award interest at the rate or rates provided herein or in the Parent Indemnity and Subsidiary Guarantee Letter Agreement. If the property or any portion thereof is taken by the power of eminent domain, Grantor shall promptly commence and diligently prosecute the Restoration of the Property in accordance with this Deed of Trust. If the Property is sold, through foreclosure or otherwise, prior to the receipt by Beneficiary of the award or payment, Beneficiary shall have the right, whether or not a deficiency judgment on the Parent Indemnity and Subsidiary Guarantee Letter Agreement shall have been sought, recovered or denied, to receive the award or payment, or a portion thereof sufficient to pay the Secured Obligations.

2.13     Restoration After Casualty or Condemnation.

In the event of a casualty or a taking by eminent domain, the following provisions shall apply in connection with the Restoration of the Property:

2.13.1 If (i) the Net Proceeds (defined below) do not exceed Fifty Thousand Dollars ($50,000.00) (“Casualty Amount”); (ii) the costs of completing the Restoration as reasonably estimated by Grantor shall be less than or equal to the Casualty Amount; (iii) no Event of Default shall have occurred and be continuing under the Parent Indemnity and Subsidiary Guarantee Letter Agreement, this Deed of Trust, the other Credit Documents, or any of the Secured Obligations; (iv) the Property and the use thereof after the Restoration will be in compliance with, and permitted under, all applicable zoning laws, ordinances, rules and regulations; and (v) such fire or other casualty or taking, as applicable, does not materially impair access to the Property or the Improvements, then the Net Proceeds will be disbursed directly to Grantor and Grantor shall commence and diligently prosecute to completion, the Restoration of the Property to as nearly as possible the condition it was in immediately prior to such fire or other casualty or such taking. Except upon the occurrence and continuance of an Event of Default, Grantor shall settle any insurance claims with respect to the Net Proceeds which in the aggregate are less than or equal to the Casualty Amount. Beneficiary shall have the right to participate in and reasonably approve any settlement for insurance claims with respect to the Net Proceeds that in the aggregate are equal to or greater than the Casualty Amount. If an Event of Default shall have occurred and be continuing, Grantor irrevocably empowers Beneficiary, in the name of Grantor as its true and lawful attorney-in-fact, to file and prosecute such claim and to collect and to make receipt for any such payment. If the Net Proceeds are received by Grantor, such Net Proceeds shall, until the completion of the related work, be held in trust for Beneficiary and shall be segregated from other funds of Grantor to be used to pay for the cost of the Restoration in accordance with the terms hereof.

12

2.13.2 If the Net Proceeds are greater than the Casualty Amount, such Net Proceeds shall be paid to Beneficiary to be held by Beneficiary to be made available to Grantor for the Restoration in accordance with the provisions of this Subsection. Grantor shall commence and diligently prosecute to completion the Restoration (in the case of a taking, to the extent the Property is capable of being restored). The term “Net Proceeds” for purposes of this Section shall mean: (i) the net amount of all insurance proceeds under the Policies carried pursuant to Paragraphs 2.11.1(a), (d), (e), and (f) of this Deed of Trust as a result of such damage or destruction, after deduction of its reasonable costs and expenses (including, but not limited to reasonable counsel fees), if any, in collecting the same, or (ii) the net amount of all awards and payments received by Beneficiary with respect to a taking referenced in Section 2.12 of this Deed of Trust, after deduction of its reasonable costs and expenses (including, but not limited to reasonable counsel fees), if any, in collecting the same, whichever the case may be.

(a) The Net Proceeds shall be made available to Grantor for payment of, or reimbursement of Grantor’s expenses in connection with, the Restoration, subject to the following conditions:

(i) No Event of Default shall have occurred and be continuing under the Parent Indemnity and Subsidiary Guarantee Letter Agreement, this Deed of Trust, the other Credit Documents, or any of the Secured Obligations;

(ii) Beneficiary shall, within a reasonable period of time prior to request for initial disbursement, be furnished with an estimate of the cost of the Restoration accompanied by an architect’s certification as to such costs and appropriate plans and specifications for the Restoration;

(iii) The Net Proceeds, together with any cash or cash equivalent deposited by Grantor with Beneficiary, are sufficient to cover the cost of the Restoration as such costs are certified by the architect;

(iv) Beneficiary shall be satisfied that any operating deficits, including all scheduled payments under the Entrustment Loan Contract and the Supply Agreements which will be incurred with respect to the Property as a result of the occurrence of any such fire or other casualty or taking, whichever the case may be, will be covered out of (1) the Net Proceeds, or (2) other funds of Grantor;

(v)  [reserved];

(vi)  The  Property  and  the  use  thereof  after  the  Restoration  will  be  in compliance with, and permitted under, all applicable zoning laws, ordinances, rules and regulations; and

(vii) Such fire or other casualty or taking, as applicable, does not materially impair access to the Property or the Improvements.

13

(b) The Net Proceeds shall be held by Beneficiary and, until disbursed in accordance with the provisions of this Subsection, shall constitute additional security for the Secured Obligations. The Net Proceeds other than the Net Proceeds paid under the Policy described in Paragraph 2.11.1(c) shall be disbursed by Beneficiary to, or as directed by, Grantor from time to time during the course of the Restoration, upon receipt of evidence satisfactory to Beneficiary that (A) all materials installed and work and labor performed (except to the extent that they are to be directly paid for out of the requested disbursement) in connection with the Restoration have been paid for in full, and (B) there exist no notices of pendency, stop orders, mechanic’s or materialman’s liens or notices of intention to file same, or any other liens or encumbrances of any nature whatsoever on the Property arising out of the Restoration which have not either been fully bonded and discharged of record or in the alternative fully insured to the satisfaction of Beneficiary by the title insurance company insuring the lien of this Deed of Trust.

(c) Beneficiary shall have the use of the plans and specifications and all permits, licenses and approvals required or obtained in connection with the Restoration. The identity of the contractors, subcontractors and materialmen engaged in the Restoration, as well as the contracts under which they have been engaged, shall be subject to prior review and acceptance by Beneficiary and an independent consulting engineer selected by Beneficiary (the “Casualty Consultant”), such acceptance not to be unreasonably withheld or delayed. All costs and expenses incurred by Beneficiary in connection with making the Net Proceeds available for the Restoration including, without limitation, reasonable counsel fees and disbursements and the Casualty Consultant’s fees, shall be paid by Grantor.

(d) Beneficiary shall not be obligated to make disbursements of the Net Proceeds in excess of an amount equal to the costs actually incurred from time to time for work in place as part of the Restoration, as certified by the Casualty Consultant.

(e) Beneficiary shall not be obligated to make disbursements of the Net Proceeds more frequently than once every calendar month.

(f) If at any time the Net Proceeds or the undisbursed balance thereof shall not, in the opinion of Beneficiary, be sufficient to pay in full the balance of the costs which are estimated by the Casualty Consultant to be incurred in connection with the completion of the Restoration, Grantor shall deposit the deficiency (the “Net Proceeds Deficiency”) with Beneficiary before any further disbursement of the Net Proceeds shall be made. The Net Proceeds Deficiency deposited with Beneficiary shall be held by Beneficiary and shall be disbursed for costs actually incurred in connection with the Restoration on the same conditions applicable to the disbursement of the Net Proceeds, and until so disbursed pursuant to this Paragraph shall constitute additional security for the Secured Obligations.

(g) The excess, if any, of the Net Proceeds and the remaining balance, if any, of the Net Proceeds Deficiency deposited with Beneficiary after the Casualty Consultant certifies to Beneficiary that the Restoration has been completed in accordance with the provisions of this Section, and the receipt by Beneficiary of evidence satisfactory to Beneficiary that all costs

14

incurred in connection with the Restoration have been paid in full, shall be remitted by Beneficiary to Grantor, provided no Event of Default shall have occurred and shall be continuing under the Parent Indemnity and Subsidiary Guarantee Letter Agreement, this Deed of Trust, the other Credit Documents or any of the Secured Obligations.

2.14 Compliance with Laws. Grantor shall observe, abide by, and comply with all statutes, ordinances, laws, orders, requirements or decrees relating to the Property enacted, promulgated or issued by any federal, state, county or local governmental authority or any agency or subdivision thereof having jurisdiction over Grantor or the Property. Grantor shall observe and comply with all conditions and requirements necessary to preserve and extend any and all rights, licenses, permits (including, but not limited to, zoning, variances, special exceptions and nonconforming uses), privileges, franchises and concessions that are applicable to the Property or that have been granted to or contracted for by Grantor in connection with any existing, presently contemplated or future use of the Property.

2.15 Maintenance of Permits. Grantor shall obtain, keep, and constantly maintain in full force and effect during the entire term of this Deed of Trust all certificates, licenses and permits necessary to keep the Property operating as a polysilicon manufacturing facility. Except as specifically provided for in this Deed of Trust, Grantor shall not assign, transfer or in any manner change such certificates, licenses or permits without first receiving the written consent of Beneficiary.

2.16 Obligations of Grantor as Lessor. Grantor shall perform every obligation of Grantor (as the lessor) and enforce every obligation of the lessee in each lease or other occupancy agreement of the Property or any part thereof under which Grantor is the lessor or the grantor of occupancy rights (the “Occupancy Leases”), if any. Grantor shall not modify, alter, waive, or cancel any Occupancy Lease or any part thereof, without the prior written consent of Beneficiary, which consent shall not be unreasonably withheld (but such consent shall not be required for such action as to Occupancy Leases if such action is in the ordinary course of business of owning and operating the Property in a prudent manner). Grantor, except as provided for in this Deed of Trust, shall not assign any Occupancy Lease or any rents to any party other than Beneficiary, without the prior written consent of Beneficiary, which consent shall not be unreasonably withheld. In the event of default under any Occupancy Lease by reason of failure of the Grantor to keep or perform one or more of the covenants, agreements or conditions thereof, Beneficiary is authorized and empowered, and may, at its sole option, remedy, remove or cure any such default, and further, Beneficiary may, at its sole option and in its sole discretion, but without obligation to do so, pay any sum of money deemed necessary by it for the performance of said covenants, agreements and conditions, or for the curing or removal of any such default, and incur all expenses and obligations which it may consider necessary or reasonable in connection therewith, and Grantor shall repay on demand all such sums so paid or advanced by Beneficiary together with interest thereon until paid at the then applicable interest rate of the Entrustment Loan Contract plus ten (10) basis points. All such sums, if unpaid, shall be added to and become part of the indebtedness secured hereby. All Occupancy Leases hereafter made shall be subject to the approval of Beneficiary and (a) shall be at competitive market rental rates then prevailing in the geographic area for property comparable to the Property,

15

and (b) at Beneficiary’s option, shall be superior or subordinate in all respects to the lien of this Deed of Trust. Beneficiary shall not require approval in advance of any Occupancy Leases that conform to the Grantor’s Form Lease (as defined below) as previously approved by Beneficiary, except as set forth below.

2.16.1 Grantor shall not, without the prior written consent of Beneficiary, surrender or terminate, either orally or in writing, any Occupancy Lease now existing or hereafter made with any Major Tenant (as defined below) for all or part of the Property, permit an assignment or sublease of any such Occupancy Lease, except as set forth in the Occupancy Lease, or request or consent to the subordination of any Occupancy Lease to any lien subordinate to this Deed of Trust. If requested, Grantor shall furnish Beneficiary with copies of all executed Occupancy Leases of all or any part of the Property now existing or hereafter made, and Grantor shall assign to Beneficiary (which assignment shall be in form and content acceptable to Beneficiary), as additional security for the Parent Indemnity and Subsidiary Guarantee Letter Agreement and the Supply Agreements, all Occupancy Leases now existing or hereafter made for all or any part of the Property. Additionally, if any tenant lease contains a provision allowing the tenant to terminate their lease upon payment of a lease termination fee, Grantor agrees that all such sums shall be paid to Beneficiary so long as this Deed of Trust is in effect and held by Beneficiary to be applied to the obligations secured by this Deed of Trust until a new tenant is secured for the space at the same or higher rent. All funds held by Beneficiary shall be applied to regular payments due under the Parent Indemnity and Subsidiary Guarantee Letter Agreement and the Supply Agreements and not for prepayment unless there is a default hereunder.

2.16.2 Beneficiary hereby specifically reserves the right to approve all prospective tenants under all Occupancy Leases hereafter proposed to be made if: (i) the term thereof, excluding options to renew the same, exceeds five (5) years; or (ii) the net rentable area to be occupied thereunder, including expansion options, exceeds ten percent (10%) of the net leasable area of the Improvements (the tenants under such leases are referred to as “Major Tenants”). Grantor shall notify Beneficiary in writing of all prospective Major Tenants and shall deliver to Beneficiary, at Grantor’s sole cost and expense, information about the prospective Major Tenant reasonably requested by Beneficiary.

2.17 Funds Held by Beneficiary for Taxes, Insurance Premiums, and Other Charges. In order to more fully protect the security of this Deed of Trust, Grantor shall, upon the request of Beneficiary at any time following the occurrence of an Event of Default, deposit with Beneficiary, together with and in addition to each monthly payment due on account of the indebtedness evidenced by the Entrustment Loan Contract, an amount equal to one twelfth (1/12) of the annual total of such taxes, assessments, insurance premiums, and other charges (all as estimated by Beneficiary in its sole discretion) so that, at least thirty (30) days prior to the due date thereof, Beneficiary shall be able to pay in full all such taxes, assessments, insurance premiums, and other charges as the same shall become due, and Beneficiary may hold without paying interest and commingle with its general funds the sums so deposited and apply the same to the payment of such taxes, assessments, insurance premiums, or other charges as they become due and payable. If at any time the funds so held by Beneficiary are insufficient to pay such taxes, assessments, insurance premiums, or other charges as they become due and payable,

16

Grantor shall immediately, upon notice and demand by Beneficiary, deposit with Beneficiary the amount of such deficiency, and the failure on the part of Grantor to do so shall entitle Beneficiary, at its sole option, to make such payments in accordance with its right and pursuant to the conditions elsewhere provided in this Deed of Trust. Whenever any default exists under this Deed of Trust, Beneficiary may, at its sole option but without an obligation so to do, apply any funds so held by it pursuant to this Section toward the payment of the indebtedness secured hereby, notwithstanding the fact that the amount owing thereon may not then be due and payable or that said indebtedness may otherwise be adequately secured in such order and manner of application as Beneficiary may elect.

2.18 Examination of Grantor’s Records. Grantor shall maintain complete and accurate books and records showing in detail the income and expenses of the Property, and shall permit Beneficiary and its representatives to examine such books and records and all supporting vouchers and data during normal business hours and from time to time upon request by Beneficiary, in such place as such books and records are customarily kept, and shall furnish to Beneficiary, within sixty (60) days after the close of each fiscal year of Grantor, annual statements (income statements and a balance sheet) for the Grantor and the Property in a form acceptable to Beneficiary and shall be prepared in accordance with generally accepted accounting principles, and shall include a rent roll, certified as true and correct by Grantor and showing in detail all income derived from and expenses incurred in connection with the ownership of the Property. Upon the occurrence of an Event of Default, Beneficiary shall have the right to require that the financial statements be audited and certified by a certified public accountant acceptable to Beneficiary, at the sole cost and expense of Grantor.

3.   Representations and Warranties.  Grantor represents and warrants to Beneficiary that:

3.1 Warranty of Title. Grantor has good right, title and interest in and to the Property, subject to the Ground Lease; Grantor has the right to mortgage, grant, bargain, sell, pledge, assign, warrant, transfer and convey the same; Grantor possesses a leasehold interest in the Real Property pursuant to the Ground Lease; and, subject to the Ground Lease, Grantor owns the Improvements and the Property free and clear of all liens, encumbrances and charges whatsoever except for the Ground Lease and other matters currently of record.

Grantor does not know of any basis for any additional assessment in respect of any such taxes and related liabilities for prior years.

4.   Further Assurances.

4.1 Inspection by Beneficiary.

Grantor shall not, without the prior written consent of Beneficiary, sell, convey, mortgage, grant, bargain, encumber, pledge, assign, or otherwise transfer the Property or any part thereof or permit the Property or any part thereof to be sold, conveyed, mortgaged, granted, bargained, encumbered, pledged, assigned, or otherwise transferred. A sale, conveyance, mortgage, grant, bargain, encumbrance, pledge, assignment, or transfer within the meaning of this Section shall be deemed to include, but not limited to (a) an installment sales agreement wherein Grantor agrees to sell the Property or any part thereof for a price to be paid in installments; (b) an agreement by Grantor leasing all or a substantial part of the Property for other than actual occupancy by a space tenant thereunder or a sale, assignment or other transfer of, or the grant of a security interest in, Grantor’s right, title and interest in and to any Leases or any Rents; (c) if Grantor or any general partner or managing member (or if no managing member, any member) of Grantor is a corporation, the voluntary or involuntary sale, conveyance, transfer or pledge of such corporation’s stock (or the stock of any corporation directly or indirectly controlling such corporation by operation of law or otherwise) or the creation or issuance of new stock by which an aggregate of more than 49% of such corporation’s stock shall be vested in a party or parties who are not now owners of more than 49% of such corporation’s stock; and (d) if Grantor or any general partner or managing member (or if no managing member, any member) of Grantor is a limited or general partnership or joint venture, the change, removal or resignation of a general partner or the transfer or pledge of the partnership interest of any general partner or any profits or proceeds relating to such partnership interest, and (e) if Grantor or any general partner or member of Grantor is a limited liability company, the change, removal or resignation of a managing member (or if no managing member, any member) or the transfer of the membership interest of a managing member (or if no managing member, any member) or any profits or proceeds relating to such membership interest.

Any notice of sale, disposition or other intended action by Beneficiary with respect to the Personal Property sent to Grantor in accordance with the provisions hereof at least ten days prior to such action, shall constitute commercially reasonable notice to Grantor.

7.1.8 Apply the undisbursed balance of any Net Proceeds or any Net Proceeds Deficiency deposit, together with interest thereon, to the payment of the Secured Obligations in such order, priority and proportions as Beneficiary shall deem to be appropriate in its discretion.

7.1.9    Pursue such other remedies as Beneficiary may have under applicable law.

21

Notwithstanding the provisions of this Section to the contrary, if any Event of Default as described in Subsection 6.4 (i) or (ii) shall occur, the entire unpaid Secured Obligations shall be automatically due and payable, without any further notice, demand or other action by Beneficiary.

7.2 Foreclosure by Power of Sale. If Beneficiary elects to foreclose by exercise of the power of sale herein contained, Beneficiary shall notify Trustee and shall deposit with the Trustee this Deed of Trust, the Parent Indemnity and Subsidiary Guarantee Letter Agreement and such receipts and evidence of expenditures made and secured hereby as Trustee may require. Upon receipt of such notice from Beneficiary, Trustee shall cause to be recorded and given all notices required by law. Trustee shall, without demand on Grantor, after lapse of such time as may then be required by law and after recordation of such Notice of Default and after Notice of Sale having been given as required by law, sell the Property at the time and place of sale fixed by it in said Notice of Sale either as a whole, or in separate lots or parcels as Trustee shall deem expedient, unless Beneficiary specifies certain terms and conditions that are permitted by applicable law, and in such order as it may determine, at public auction to the highest bidder for cash in lawful money of the United States payable at the time of sale. The Trustee may postpone any sale by public announcement at the time and place noticed for the sale. Trustee shall deliver to such purchaser or purchasers thereof its good and sufficient deed or deeds conveying the property so sold, but without any covenant or warranty, express or implied. The recitals in such deed of any matters or facts shall be conclusive proof of the truthfulness thereof. Any person, including without limitation, Grantor, Trustee or Beneficiary, may purchase at such sale. At any judicial or trustee sale of the Property, Beneficiary may credit bid (as determined by Beneficiary in its sole and absolute discretion) all or any portion of the Secured Obligations.

7.3 Application of Proceeds. The purchase money, proceeds and avails of any disposition of the Property, or any part thereof, or any other sums collected by Beneficiary pursuant to the Parent Indemnity and Subsidiary Guarantee Letter Agreement, this Deed of Trust or the other Credit Documents, may be applied by Beneficiary to the payment of the Secured Obligations in such priority and proportions as Beneficiary in its discretion shall deem proper, subject to any applicable law.

7.4 Right to Cure Defaults. Upon the occurrence of any Event of Default, Beneficiary may, but without any obligation to do so and without notice to or demand on Grantor and without releasing Grantor from any obligation hereunder, cure the same in such manner and to such extent as Beneficiary may deem necessary to protect the security hereof. Beneficiary is authorized to enter upon the Property for such purposes, or appear in, defend, or bring any action or proceeding to protect its interest in the Property or to foreclose this Deed of Trust or collect the Secured Obligations, and the cost and expense thereof (including reasonable attorneys’ fees to the extent permitted by law), with interest as provided in this Section, shall constitute a portion of the Secured Obligations and shall be due and payable to Beneficiary upon demand. All such costs and expenses incurred by Beneficiary in remedying such Event of Default or in appearing in, defending, or bringing any such action or proceeding shall bear interest at the default rate specified in the Entrustment Loan Contract (the “Default Rate”), for the period after notice from Beneficiary that such cost or expense was incurred to the date of payment to Beneficiary. All

22

such costs and expenses incurred by Beneficiary together with interest thereon calculated at the Default Rate shall be deemed to constitute a portion of the Secured Obligations and be secured by this Deed of Trust and the other Credit Documents and shall be immediately due and payable upon demand by Beneficiary therefor.

7.5 Examination of Books and Records. Beneficiary, its agents, accountants and attorneys shall have the right upon prior written notice to examine the records, books, management and other papers of Grantor and its affiliates that reflect upon their financial condition, at the Property or at any office regularly maintained by Grantor, its affiliates or any Guarantor where the books and records are located. Beneficiary and its agents shall have the right upon notice to make copies and extracts from the foregoing records and other papers. In addition, Beneficiary, its agents, accountants and attorneys shall have the right to examine and audit the books and records of Grantor and its affiliates or of any Guarantor pertaining to the income, expenses and operation of the Property during reasonable business hours at any office of Grantor, its affiliates or any Guarantor where the books and records are located.

7.6  Other Rights.

7.6.1 The failure of Beneficiary to insist upon strict performance of any term hereof shall not be deemed to be a waiver of any term of this Deed of Trust. Grantor shall not be relieved of Grantor’s obligations hereunder by reason of (i) the failure of Beneficiary to comply with any request of Grantor to take any action to foreclose this Deed of Trust or otherwise enforce any of the provisions hereof or of the Parent Indemnity and Subsidiary Guarantee Letter Agreement, the other Credit Documents or the Secured Obligations, (ii) the release, regardless of consideration, of the whole or any part of the Property, or of any person liable for the Secured Obligations or any portion thereof, or (iii) any agreement or stipulation by Beneficiary extending the time of payment or otherwise modifying or supplementing the terms of the Parent Indemnity and Subsidiary Guarantee Letter Agreement, this Deed of Trust, the other Credit Documents or the Secured Obligations.

7.6.2 The risk of loss or damage to the Property is on Grantor, and Beneficiary shall have no liability whatsoever for decline in value of the Property, for failure to maintain the Policies, or for failure to determine whether insurance in force is adequate as to the amount of risks insured. Possession by Beneficiary shall not be deemed an election of judicial relief, if any such possession is requested or obtained, with respect to any Property or collateral not in Beneficiary’s possession.

7.6.3 Beneficiary may resort for the payment and/or performance of the Secured Obligations to any other security held by Beneficiary in such order and manner as Beneficiary, in its discretion, may elect. Beneficiary may take action to recover the Secured Obligations, or any portion thereof, or to enforce any covenant hereof without prejudice to the right of Beneficiary thereafter to foreclose this Deed of Trust. The rights of Beneficiary under this Deed of Trust shall be separate, distinct and cumulative and none shall be given effect to the exclusion of the others. No act of Beneficiary shall be construed as an election to proceed under any one provision herein to the exclusion of any other provision. Beneficiary shall not be limited exclusively to the rights and remedies herein stated but shall be entitled to every right and remedy now or hereafter afforded at law or in equity.

23

7.7 Beneficiary’s Power. Beneficiary may release or reconvey any portion of the Property for such consideration as Beneficiary may require without, as to the remainder of the Property, in any way impairing or affecting the lien or priority of this Deed of Trust, or improving the position of any subordinate lienholder with respect thereto, except to the extent that the obligations hereunder shall have been reduced by the actual monetary consideration, if any, received by Beneficiary for such release or reconveyance, and may accept by assignment, pledge or otherwise any other property in place thereof as Beneficiary may require without being accountable for so doing to any other lienholder. This Deed of Trust shall continue as a lien and security interest in the remaining portion of the Property. Without affecting the liability of any other person liable for the payment and/or performance of the Obligations and without in any way impairing or affecting the lien or priority of this Deed of Trust, Beneficiary may, from time to time and without notice (i) release any person so liable; (ii) extend the maturity or alter any of the terms of any Secured Obligation; (iii) grant other indulgences; or (iv) make compositions or other arrangements with debtors in relation thereto.

7.8 Right of Entry. Beneficiary and its agents shall have the right upon prior written notice to enter and inspect the Property at all reasonable times upon notice to Grantor.

7.9 Acceptance of Trust; Powers and Duties of Trustee. Trustee accepts this trust when this Deed of Trust is recorded. From time to time upon written request of Beneficiary and presentation of this Deed of Trust, or a certified copy thereof, for endorsement, and without affecting the personal liability of any person for payment of any indebtedness or performance of any other Obligation, Trustee may, without liability therefor and without notice: (a) reconvey all or any part of the Property; (b) consent to the making of any map or plat of the Property; (c) join in granting any easement on the Property; (d) join in any declaration of covenants and restrictions; or (e) join in any extension agreement or any agreement subordinating the lien or charge of this Deed of Trust. Nothing contained in the immediately preceding sentence shall be construed to limit, impair or otherwise affect the rights of Trustee in any respect. Trustee is not obligated to notify any party hereto of pending sale under any other deed of trust or of any action or proceeding in which Grantor, Beneficiary, or Trustee shall be a party unless brought by Trustee.

7.10 Substitution of Trustee. Beneficiary may at any time, and from time to time, and without notice, replace and substitute a new trustee in place of the existing Trustee under this Deed of Trust, in the manner provided for under, and as allowed by, current Idaho law.

7.11 Reconveyance by Trustee. Upon written request of Beneficiary stating that all sums secured hereby have been paid and upon surrender of this Deed of Trust to Trustee for cancellation and retention and upon payment by Grantor of Trustee’s fees, Trustee shall reconvey to Grantor, or the person or persons legally entitled thereto, without warranty, any portion of the Property then held hereunder. The recitals in such reconveyance of any matters or facts shall be conclusive proof of the truthfulness thereof.

24

8. Indemnification. If Beneficiary shall become a party either as plaintiff or as defendant, in any action, suit, appeal or legal proceeding (including, without limitation, foreclosure, condemnation, bankruptcy, administrative proceedings or any proceeding wherein proof of claim is by law required to be filed), hearing, motion or application before any court or administrative body in relation to the Property or the lien and security interest granted or created hereby or herein, or for the recovery or protection of said indebtedness or the Property, or for the foreclosure of this Deed of Trust, Grantor shall save and hold Beneficiary harmless from and against any and all costs and expenses incurred by Beneficiary on account thereof, including, but not limited to, Reasonable Attorneys’ Fees, title searches and abstract and survey charges, at all trial and appellate levels, and Grantor shall repay, on demand, all such costs and expenses, together with interest thereon until paid at the then applicable rate of interest of the Entrustment Loan Contract plus ten (10) basis points; all of which sums, if unpaid, shall be added to and become a part of the indebtedness secured hereby.

9. Usury Savings Clause. Notwithstanding any provisions in the Parent Indemnity and Subsidiary Guarantee Letter Agreement or in this Deed of Trust to the contrary, the total liability for payments in the nature of interest including but not limited to default interest and late payment charges shall not exceed the limits imposed by the laws of the State of Idaho or, if controlling, the United States relating to maximum allowable charges of interest. Beneficiary shall not be entitled to receive, collect or apply, as interest on the obligations evidenced by the Parent Indemnity and Subsidiary Guarantee Letter Agreement or the Supply Agreements, any amount in excess of the maximum lawful rate of interest permitted to be charged by applicable law. If Beneficiary ever receives, collects or applies as interest any such excess, such amount that would be excessive interest shall be applied to reduce the unpaid principal balance of the obligations evidenced by the Parent Indemnity and Subsidiary Guarantee Letter Agreement and the Supply Agreements. If the unpaid principal balance of such obligations has been paid in full, any remaining excess shall be paid to Grantor.

10. Notices. All notices or other written communications hereunder shall be deemed to have been properly given (a) upon delivery, if delivered in person or by facsimile transmission with receipt acknowledged by the recipient thereof, (b) one (1) business day after having been deposited for overnight delivery with any reputable overnight courier service, or (c) three (3) business days after having been deposited in any post office or mail depository regularly maintained by the U.S. Postal Service and sent by registered or certified mail, postage prepaid, return receipt requested, addressed as follows:

__________ __, 2009

Tianwei New Energy Holdings Co., Ltd.

No 0, Xxxxxxx Xxxx,

Xxxxxxxxx Airport Economic Development Zone,

Chengdu, China 610200

Attention: Xxx Xxx

Re:      Parent Indemnity and Subsidiary Guarantee

Ladies and Gentlemen:

Reference is made to the letter agreement (the “Loan Implementation Agreement”) dated as of December 22, 2009 among Tianwei New Energy Holdings Co., Ltd., a corporation organized under the laws of the People’s Republic of China (“Tianwei”), Hoku Scientific, Inc., a Delaware corporation (the “Company”) and Hoku Materials, Inc., a Delaware corporation and a wholly-owned subsidiary of the Company (“Hoku Materials”). Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the Loan Implementation Agreement.

1. The Company shall indemnify and hold harmless Tianwei, its Affiliates (as defined below), and their respective directors, officers, employees, counsel, agents and attorneys-in-fact (collectively the “Indemnitees”) from and against any and all liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses and disbursements of any kind or nature whatsoever which may at any time be imposed on, incurred by or asserted against any such Indemnitee in any way relating to or arising out of or in connection with (a) the execution, delivery, enforcement, performance or administration of the Loan Contracts or any other agreement, letter or instrument delivered in connection with the transactions contemplated thereby or the consummation of the transactions contemplated thereby, (b) the Tranche 1 Loan or the Tranche 2 Loan or the use or proposed use of the proceeds therefrom or (c) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory (including any investigation of, preparation for, or defense of any pending or threatened claim, investigation, litigation or proceeding) and regardless of whether any Indemnitee is a party thereto (all the foregoing, collectively, the “Indemnified Liabilities”), in all cases, whether or not caused by or arising, in

whole or in part, out of the negligence of the Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses or disbursements are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the bad faith, gross negligence or willful misconduct of such Indemnitee (the “Indemnity”). Notwithstanding the foregoing, the Company shall have no obligation to pay under the Indemnity (i) the amount of any portion of the Tranche 1 Loan or the Tranche 2 Loan to the extent not released by China Construction Bank Corporation Shuangliu Sub-Branch (the “Bank”) to the Company or (ii) the amount of any portion of the Tranche 1 Loan or the Tranche 2 Loan repaid by the Company to the Bank or any other amount payable to Tianwei under the Loan Implementation Agreement paid by the Company to the Bank that the Bank shall have failed to pay over Tianwei; provided that the exclusion from the Indemnity set forth in this sentence shall be limited precisely as written and shall not relieve the Company from its obligations under the Indemnity in respect of any amount other than the amounts expressly set forth in clauses (i) and (ii) hereof. No Indemnitee shall have any liability for any indirect or consequential damages relating to this letter agreement or the Loan Contracts or arising out of its activities in connection herewith or therewith. All amounts due under this letter agreement shall be payable within ten Business Days after demand therefor. The agreements in this paragraph 1 shall survive the termination of the Loan Contracts and the repayment, satisfaction or discharge of all the other obligations thereunder. “Affiliate” means, with respect to any person, another person that directly, or indirectly through one or more intermediaries, Controls or is Controlled by or is under common Control with the person specified. “Control” means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of a person, whether through the ability to exercise voting power, by contract or otherwise. “Controlling” and “Controlled” have meanings correlative thereto.

2. As a condition of and inducement to the willingness of Tianwei and the Bank to enter into the Loan Contracts, Hoku Materials hereby irrevocably and unconditionally, as primary obligor, undertakes and guarantees the full, prompt and complete performance by the Company of all its obligations under the Indemnity, and the due and punctual payment of all sums then or subsequently payable by the Company to Tianwei or the Bank under the Indemnity (including any interest that accrues after the commencement of any case, proceeding or other action relating to the bankruptcy, insolvency or reorganization of the Company (or would accrue but for the operation of applicable bankruptcy or insolvency laws)) when the same shall become due (whether at stated maturity, upon acceleration or otherwise) (the “Subsidiary Guarantee”). The Subsidiary Guarantee is a guaranty of payment and not of collection.

3. The obligations of Hoku Materials under the Indemnity shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by:

2

(i) any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Company or any other guarantor or any other person or entity under the Indemnity or the Loan Contracts or any other agreement or instrument entered into or delivered in connection therewith, by operation of law or otherwise;

(ii) any modification or amendment of or supplement to the Indemnity or the Loan Contracts or any other agreement or instrument entered into or delivered in connection therewith;

(iii) any release, impairment, non-perfection or invalidity of any direct or indirect security for any obligation of the Company or any other guarantor or any other person or entity under the Indemnity or the Loan Contracts or any other agreement or instrument entered into or delivered in connection therewith;

(iv) any change in the corporate or other existence, structure or ownership of the Company or any other guarantor or any other person or entity, or any insolvency, bankruptcy, suspension of payments, reorganization or other similar proceeding affecting the Company or any other guarantor or any other person or entity or any of their assets or any resulting release or discharge of any obligation of the Company or any other guarantor or any other person or entity contained in the Indemnity or the Loan Contracts or any other agreement or instrument entered into or delivered in connection therewith;

(v) the existence of any claim, set-off or other rights that Hoku Materials may have at any time against the Company or any other guarantor, Tianwei, the Bank or any other person or entity, whether in connection with the Indemnity or the Loan Contracts or any other agreement or instrument entered into or delivered in connection therewith or any unrelated transactions, provided that nothing contained in this letter agreement shall prevent the assertion of any such claim by separate suit or compulsory counterclaim;

(vi) any invalidity or unenforceability relating to or against Hoku Scientific or any other guarantor or any other person or entity for any reason of the Indemnity or the Loan Contracts or any other agreement or instrument entered into or delivered in connection therewith, or any provision of applicable law or regulation purporting to prohibit the payment of any amount payable pursuant to the Indemnity or the Loan Contracts or any other agreement or instrument entered into or delivered in

3

connection therewith by Hoku Scientific or any other guarantor or any other person or entity; or

(vii) any other act or omission to act or delay of any kind by Hoku Scientific or any other guarantor, any other party to the Indemnity or the Loan Contracts or any other agreement or instrument entered into or delivered in connection therewith, Tianwei or the Bank or any other person or entity, or any other circumstance whatsoever which might, but for the provisions of this clause (vii), constitute a legal or equitable discharge of or defense to any obligation of Hoku Materials hereunder.

4. Hoku Materials shall be liable under the Indemnity and the Subsidiary Guarantee only for amounts aggregating up to the largest amount that would not render its obligations hereunder subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provision of any other applicable law.

5. The obligations of Hoku Materials hereunder shall remain in full force and effect until all amounts payable by the Company under the Indemnity shall have been paid in full. If at any time any payment of any obligation hereunder is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, Hoku Materials’ obligations hereunder with respect to such payment shall be reinstated as though such payment had been due but not made at such time.

6.  Hoku Materials irrevocably waives:

(i) acceptance hereof, presentment, demand, protest and any notice not provided for hereunder, as well as any requirement that at any time any action be taken by any person or entity against the Company or any other guarantor or any other person or entity;

(ii) any right to which it may be entitled in connection with any obligation of Tianwei or the Bank to xxx or initiate any action and/or complete an action against the Company or any other guarantor or any other person or entity prior to a claim being made against Hoku Materials pursuant hereto;

(iii) any right to which it may be entitled to have the assets of the Company or any other guarantor or any other person or entity first be used and/or applied in full and/or depleted as payment of the Company’s or any such other guarantor’s obligations hereunder, prior to any amounts being claimed from or paid by Hoku Materials pursuant hereto; and

4

(iv) any right to which it may be entitled to have its obligations hereunder divided among itself and one or more other guarantors.

7. If Hoku Materials makes a payment with respect to any obligation hereunder, it shall be subrogated to the rights of the payee against the Company with respect to such payment; provided that Hoku Materials shall not enforce any payment by way of subrogation against the Company, or by reason of contribution against any other guarantor of such obligation, until the principal of and interest on the Tranche 1 Loan and the Tranche 2 Loan and all fees payable thereunder have been paid in full.

8. If any provision contained in this letter agreement shall for any reason be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this letter agreement, but this letter agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

9. This letter agreement shall be binding upon and shall inure to the benefit of and be enforceable by each of the parties hereto and their respective successors and permitted assigns (but no other persons). Any assignment by Hoku Materials of any of its rights or obligations under this letter agreement shall be subject to the prior written consent of Tianwei.

10. No amendment or waiver of any provision of this letter agreement shall be binding unless executed in writing by each of the parties hereto. No oral amendments or modifications of this letter agreement shall be binding between the parties.

11. This letter agreement will become effective upon the execution and delivery hereof. This letter agreement constitutes the entire agreement between the parties with respect to the subject matter of hereof and supersedes the Original Parent Guarantee.

12. This letter agreement shall be governed by and construed in accordance with the law of the State of New York, without regard to the conflicts of law rules of such state.
