Notwithstanding anything in this Agreement, any other Loan Document or any Platinum Lease to the contrary, (A) the Collateral shall not include any securities or other property referred to in clauses (a) through (f) above, or any rights and privileges with respect to, or proceeds of, any of such securities or other property, (i) if the Administrative Agent determines, after consultation with the Borrower that granting a

2

security interest in such securities or other property would (x) violate the law of the jurisdiction in which such securities or other property are located or the law of the jurisdiction where the Person owning such securities or property is organized, (y) violate the terms of any material contract binding on STX, the Borrower or any Subsidiary (but only to the extent that the restrictions in all such contracts, taken as a whole, do not materially limit the Collateral that would otherwise be pledged pursuant to the Collateral and Guarantee Requirement and Section 5.14 of the Credit Agreement to secure the Obligations) or (z) result in a material adverse tax consequence to the Loan Party granting such security interest or (ii) if the Administrative Agent shall determine that the cost to STX, the Borrower or any Grantor of granting and perfecting a Lien in such securities or other propert y would be excessive in view of the related benefits to be received by the Lenders therefrom, provided that any securities or other property excluded as Collateral pursuant to this clause (ii) shall be specified on Schedule III, as modified by the Administrative Agent from time to time, and (B) (i) the pledge of Equity Interests of any CFC Subsidiaries of a U.S. Subsidiary to secure the Obligations of any U.S. Loan Party shall not include (x) more than 65% of the outstanding voting Equity Interests of each “first tier” CFC Subsidiary directly owned by such U.S. Subsidiary or (y) any Equity Interests of any CFC Subsidiary of such U.S. Subsidiary that is not a “first tier” CFC Subsidiary of such U.S. Subsidiary and (ii) the pledge of Equity Interests of any Qualified CFC Holding Company of any U.S. Subsidiary to secure the Obligations of any U.S. Loan Party shall not include (x) more than 65% of the outstanding voting Equity Interests of each “ first tier” Qualified CFC Holding Company directly owned by such U.S. Subsidiary and (y) any Equity Interests of any Qualified CFC Holding Company of such U.S. Subsidiary that is not a “first tier” Qualified CFC Holding Company of such U.S. Subsidiary.

SECTION 4.  Registration in Nominee Name; Denominations. The Administrative Agent, on behalf of the Secured Parties, shall have the right (in its sole and absolute discretion) to hold the Pledged Securities in its own name as pledgee, the

4

name of its nominee (as pledgee or as sub-agent) or the name of the Pledgors, endorsed or assigned in blank or in favor of the Administrative Agent.  Each Pledgor will promptly give to the Administrative Agent copies of any notices or other communications received by it with respect to Pledged Securities registered in the name of such Pledgor.  The Administrative Agent shall at all times have the right to exchange the certificates representing Pledged Securities for certificates of smaller or larger denominations for any purpose consistent with this Agreement.

SECTION 5.  Voting Rights; Dividends and Interest, etc.  (a)  Unless and until an Event of Default shall have occurred and be continuing:

(i)  Each Pledgor shall be entitled to exercise any and all voting and/or other consensual rights and powers inuring to an owner of Pledged Securities or any part thereof for any purpose consistent with the terms of this Agreement, the Credit Agreement and the other Loan Documents; provided, however, that such Pledgor will not be entitled to exercise any such right if the result thereof could, in the reasonable judgment of the Administrative Agent, materially impair the Collateral, or could materially and adversely affect the rights inuring to a holder of the Pledged Securities or the rights and remedies of any of the Secured Parties under this Agreement or the Credit Agreement or any other Loan Document or the ability of the Secured Parties to exercise the same.

(ii)  The Administrative Agent shall execute and deliver to each Pledgor, or cause to be executed and delivered to each Pledgor, all such proxies, powers of attorney and other instruments as such Pledgor may reasonably request for the purpose of enabling such Pledgor to exercise the voting and/or consensual rights and powers it is entitled to exercise pursuant to subparagraph (i) above and to receive the cash dividends it is entitled to receive pursuant to subparagraph (iii) below.

(iii)  Each Pledgor shall be entitled to receive and retain any and all cash dividends, interest and principal paid on the Pledged Securities to the extent and only to the extent that such cash dividends, interest and principal are permitted by, and otherwise paid in accordance with, the terms and conditions of the Credit Agreement, the other Loan Documents and applicable laws.  All noncash dividends, interest and principal, and all dividends, interest and principal paid or payable in cash or otherwise in connection with a partial or total liquidation or dissolution, return of capital, capital surplus or paid-in surplus, and all other distributions (other than distributions referred to in the preceding sentence) made on or in respect of the Pledged Securities, whether paid or payable in cash or otherwise, whether resulting from a subdivision, combination or reclassification of th e outstanding capital stock of the issuer of any Pledged Securities or received in exchange for Pledged Securities or any part thereof, or in redemption thereof, or as a result of any merger, consolidation, acquisition or other exchange of assets to which such issuer may be a party or otherwise, shall be and become part of the Collateral, and, if received by any Pledgor, shall not be commingled by such Pledgor with any of its other funds or property but shall be held separate and apart

5

therefrom, shall be held in trust for the benefit of the Administrative Agent and shall be forthwith delivered to the Administrative Agent in the same form as so received (with any necessary endorsement).

(b)  Upon the occurrence and during the continuance of an Event of Default, all rights of any Pledgor to dividends, interest or principal that such Pledgor is authorized to receive pursuant to paragraph (a)(iii) above shall cease, and all such rights shall thereupon become vested in the Administrative Agent, which shall, subject to the provisions of this paragraph (b), have the sole and exclusive right and authority to receive and retain such dividends, interest or principal.  All dividends, interest or principal received by the Pledgor contrary to the provisions of this paragraph (b) shall be held in trust for the benefit of the Administrative Agent, shall be segregated from other property or funds of such Pledgor and shall be forthwith delivered to the Administrative Agent upon demand in the same form as so received (with any necessary endorsement).  An y and all money and other property paid over to or received by the Administrative Agent pursuant to the provisions of this paragraph (b) shall be retained by the Administrative Agent in an account to be established by the Administrative Agent upon receipt of such money or other property and shall be applied in accordance with the provisions of Section 7.  After all Events of Default have been cured or waived, the Administrative Agent shall promptly repay to each Pledgor all cash dividends, interest or principal (without interest), that such Pledgor would otherwise be permitted to retain pursuant to the terms of paragraph (a)(iii) above and that remain in such account.

(c)  Upon the occurrence and during the continuance of an Event of Default, all rights of any Pledgor to exercise the voting and consensual rights and powers it is entitled to exercise pursuant to paragraph (a)(i) of this Section 5, and the obligations of the Administrative Agent under paragraph (a)(ii) of this Section 5, shall cease, and all such rights shall thereupon become vested in the Administrative Agent, which shall have the sole and exclusive right and authority to exercise such voting and consensual rights and powers, provided that, unless otherwise directed by the Required Lenders, the Administrative Agent shall have the right from time to time following and during the continuance of an Event of Default, to permit the Pledgors to exercise such rights.  After all such Events of Default have been cured or waived, each Pledgor will have the right to exercise the voting and consensual rights and powers that it would otherwise be entitled to exercise pursuant to the terms of paragraph (a)(i) above.

SECTION 6.  Remedies upon Default.  Upon the occurrence and during the continuance of an Event of Default, subject to applicable regulatory and legal requirements, the Administrative Agent may sell the Collateral, or any part thereof, at public or private sale or at any broker’s board or on any securities exchange, for cash, upon credit or for future delivery as the Administrative Agent shall deem appropriate.  The Administrative Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale the Administrative Agent shall have the right to assign, transfer and deliver to the purchaser or p urchasers thereof the Collateral so sold.  Each such purchaser at any such

6

sale shall hold the property sold absolutely free from any claim or right on the part of any Pledgor, and, to the extent permitted by applicable law, the Pledgors hereby waive all rights of redemption, stay, valuation and appraisal any Pledgor now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted.

The Administrative Agent shall give a Pledgor 10 days’ prior written notice (which each Pledgor agrees is reasonable notice within the meaning of Section 9-611 of the Uniform Commercial Code as in effect in the State of New York or its equivalent in other jurisdictions) of the Administrative Agent’s intention to make any sale of such Pledgor’s Collateral.  Such notice, in the case of a public sale, shall state the time and place for such sale and, in the case of a sale at a broker’s board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which the Collateral, or portion thereof, will first be offered for sale at such board or exchange.  Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as the Administrative Agent may fix and state in t he notice of such sale.  At any such sale, the Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Administrative Agent may (in its sole and absolute discretion) determine.  The Administrative Agent shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given.  The Administrative Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned.  In case any sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by the Administrative Agent until the sale price is paid in full by the purchaser or purchasers thereof, but the Admi nistrative Agent shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like notice.  At any public (or, to the extent permitted by applicable law, private) sale made pursuant to this Section 6, any Secured Party may bid for or purchase, free from any right of redemption, stay or appraisal on the part of any Pledgor (all said rights being also hereby waived and released), the Collateral or any part thereof offered for sale and may make payment on account thereof by using any Obligation then due and payable to it from such Pledgor as a credit against the purchase price, and it may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to such Pledgor therefor, except that any remaining proceeds thereof shall be delivered to the Pledgors to the extent required by Section 7.  For purposes h ereof, (a) a written agreement to purchase the Collateral or any portion thereof shall be treated as a sale thereof, (b) the Administrative Agent shall be free to carry out such sale pursuant to such agreement and (c) such Pledgor shall not be entitled to the return of the Collateral or any portion thereof subject thereto, notwithstanding the fact that after the Administrative Agent shall have entered into such an agreement all Events of Default shall have been remedied and the Obligations paid in full.  As an alternative to exercising the power of sale herein conferred upon it, the Administrative Agent may proceed by a suit or suits at law or in equity to foreclose upon the Collateral and to sell the Collateral or any portion thereof

7

pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver.

SECTION 7.  Application of Proceeds of Sale.  The Administrative Agent shall apply the proceeds of any collection or sale of the Collateral, as well as any Collateral consisting of cash, as follows:

FIRST, to the payment of all costs and expenses incurred by the Administrative Agent or the Administrative Agent (in its capacity as such hereunder or under any other Loan Document) in connection with such collection or sale or otherwise in connection with this Agreement or any of the Obligations, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Administrative Agent hereunder or under any other Loan Document on behalf of any Pledgor and any other costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Loan Document;

SECOND, to the payment in full of the Obligations (the amounts so applied to be distributed among the Secured Parties pro rata in accordance with the amounts of the Obligations owed to them on the date of any such distribution); and

THIRD, to the Pledgors, their successors or assigns, or as a court of competent jurisdiction may otherwise direct.

The Administrative Agent shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Agreement.  Upon any sale of the Collateral by the Administrative Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the purchase money by the Administrative Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Administrative Agent or such officer or be answerable in any way for the misapplication thereof.

SECTION 8.  Reimbursement of Administrative Agent.  (a)  Each Pledgor jointly and severally agrees to pay upon demand to the Administrative Agent the amount of any and all reasonable expenses, including the reasonable fees, other charges and disbursements of its counsel and of any experts or agents, that the Administrative Agent may incur in connection with (i) the administration of this Agreement, (ii) the custody or preservation of, or the sale of, collection from, or other realization upon, any of the Collateral, (iii) the exercise, enforcement or protection of any of the rights of the Administrative Agent hereunder or (iv) the failure by such Pledgor to perform or observe any of the provisions hereof applicable to it.

(b)  Without limitation of its indemnification obligations under the other Loan Documents, each Pledgor jointly and severally agrees to indemnify the Administrative

8

Agent and the other Indemnitees against, and hold each of them harmless from, any and all losses, claims, damages, liabilities and related expenses, including reasonable fees, disbursements and other charges of counsel, incurred by or asserted against any of them arising out of, in any way connected with, or as a result of, the execution, delivery or performance of this Agreement or any claim, litigation, investigation or proceeding relating hereto or to the Collateral, whether or not any Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses resulted from the gross negligence or willful misconduct of such Indemnitee.

(c)  Any such amounts payable as provided hereunder shall be additional Obligations secured hereby and by the other Security Documents.  The provisions of this Section 8 shall remain operative and in full force and effect regardless of the termination of this Agreement or any other Loan Document, the consummation of the transactions contemplated hereby, the repayment of any of the Obligations, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document or any investigation made by or on behalf of the Administrative Agent or any other Secured Party.  All amounts due under this Section 8 shall be payable on written demand therefor and shall bear interest at the rate payable under Section 2.12(c)(ii) of the Credit Agreement.

SECTION 9.  Administrative Agent Appointed Attorney-in-Fact.  Each Pledgor hereby appoints the Administrative Agent the attorney-in-fact of such Pledgor for the purpose of carrying out the provisions of this Agreement and taking any action and executing any instrument that the Administrative Agent may deem necessary or advisable to accomplish the purposes hereof, which appointment is irrevocable and coupled with an interest.  Without limiting the generality of the foregoing, the Administrative Agent shall have the right, if an Event of Default shall have occurred and be continuing, with full power of substitution either in the Administrative Agent’s name or in the name of such Pledgor, to ask for, demand, sue for, collect, receive and give acquittance for any and all moneys due or to become due under and by virtue of any Collateral, to endorse checks, drafts, ord ers and other instruments for the payment of money payable to the Pledgor representing any interest or dividend or other distribution payable in respect of the Collateral or any part thereof or on account thereof and to give full discharge for the same, to settle, compromise, prosecute or defend any action, claim or proceeding with respect thereto, and to sell, assign, endorse, pledge, transfer and to make any agreement respecting, or otherwise deal with, the same; provided, however, that nothing herein contained shall be construed as requiring or obligating the Administrative Agent to make any commitment or to make any inquiry as to the nature or sufficiency of any payment received by the Administrative Agent, or to present or file any claim or notice, or to take any action with respect to the Collateral or any part thereof or the moneys due or to become due in respect thereof or any property covered thereby.  The Administrative Agent shall give prior or simultaneous notice to the Borrowe r of its intent to begin taking actions under this Section 9; provided, however, that any failure to give such notice shall in no way affect the Administrative Agent’s, right, power or authority to take such actions.  The Administrative Agent and the other Secured Parties shall be accountable only for amounts actually received as a result of the exercise of the powers granted to

9

them herein, and neither they nor their officers, directors, employees or agents shall be responsible to any Pledgor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

SECTION 10.  Waivers; Amendment.  (a)  No failure or delay of the Administrative Agent in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power.  The rights and remedies of the Administrative Agent hereunder and of the other Secured Parties under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have.  No waiver of any provisions of this Agreement or consent to any departure by any Pledgor therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shal l be effective only in the specific instance and for the purpose for which given.  No notice or demand on any Pledgor in any case shall entitle such Pledgor to any other or further notice or demand in similar or other circumstances.

(b)  Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to a written agreement entered into between the Administrative Agent and the Pledgor or Pledgors with respect to which such waiver, amendment or modification relates, subject to any consent required in accordance with Section 9.02 of the Credit Agreement.

SECTION 11.  Securities Act, etc.  In view of the position of the Pledgors in relation to the Pledged Securities, or because of other current or future circumstances, a question may arise under the Securities Act of 1933, as now or hereafter in effect, or any similar statute hereafter enacted analogous in purpose or effect (such Act and any such similar statute as from time to time in effect being called the “Federal Securities Laws”) with respect to any disposition of the Pledged Securities permitted hereunder.  Each Pledgor understands that compliance with the Federal Securities Laws might very strictly limit the course of conduct of the Administrative Agent if the Administrative Agent were to attempt to dispose of all or any part of the Pledged Securities, and might also limit the extent to which or the manner in which any subsequent transfere e of any Pledged Securities could dispose of the same.  Similarly, there may be other legal restrictions or limitations affecting the Administrative Agent in any attempt to dispose of all or part of the Pledged Securities under applicable Blue Sky or other state securities laws or similar laws analogous in purpose or effect.  Each Pledgor recognizes that in light of such restrictions and limitations the Administrative Agent may, with respect to any sale of the Pledged Securities, limit the purchasers to those who will agree, among other things, to acquire such Pledged Securities for their own account, for investment, and not with a view to the distribution or resale thereof.  Each Pledgor acknowledges and agrees that in light of such restrictions and limitations, the Administrative Agent, in its sole and absolute discretion, (a) may proceed to make such a sale whether or not a registration statement for the purpose of registering such Pledged Securities or part thereof shall have been fil ed under the Federal Securities Laws and (b) may approach and negotiate with a single potential purchaser to effect such sale, in either case in accordance with a valid

10

exemption from registration under the Federal Securities Laws.  Each Pledgor acknowledges and agrees that any such sale might result in prices and other terms less favorable to the seller than if such sale were a public sale without such restrictions.  In the event of any such sale, the Administrative Agent shall incur no responsibility or liability for selling all or any part of the Pledged Securities at a price that the Administrative Agent, in its sole and absolute discretion, may in good faith deem reasonable under the circumstances, notwithstanding the possibility that a substantially higher price might have been realized if the sale were deferred until after registration as aforesaid or if more than a single purchaser were approached.  The provisions of this Section 11 will apply notwithstanding the existence of a public or private market upon which the quotations or sales prices may e xceed substantially the price at which the Administrative Agent sells.

SECTION 12.  [Intentionally Omitted]

SECTION 13.  Security Interest Absolute.  All rights of the Administrative Agent hereunder, the grant of a security interest in the Collateral and all obligations of each Pledgor hereunder, shall be absolute and unconditional irrespective of (a) any lack of validity or enforceability of the Credit Agreement, any other Loan Document, any Platinum Lease, agreement with respect to any of the Obligations or any other agreement or instrument relating to any of the foregoing, (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure from the Credit Agreement, any other Loan Document, any Platinum Lease or any other agreement or instrument relating to any of the foregoing, (c) any exchange, release or nonperfection of any other collateral, or any release or amendment or waiver of or consent to or departure from any guaranty, for all or any of the Obligations or (d) any other circumstance that might otherwise constitute a defense available to, or a discharge of, any Pledgor in respect of the Obligations or in respect of this Agreement (other than, in the case of any Secured Party, the payment in full in cash of all the  Obligations owing to such Secured Party).

SECTION 14.  Termination or Release.  (a)  This Agreement and the security interests granted hereby shall terminate when all the Loan Document Obligations have been paid in full in cash, the Commitments have expired or been terminated, the principal and interest on each Loan and all fees payable under the Loan Documents shall have been paid in full, all Letters of Credit shall have expired or been terminated (or otherwise provided for in a manner satisfactory to the applicable Issuing Bank) and all LC Disbursements shall have been reimbursed (with such date referred to as the “Termination Date”), provided that if Specified Obligations (as defined in the U.S. Guarantee Agreement) remain outstanding on the Termination Date, then this Agreement and the security interest created hereby shall not terminate as to a particular Secured Party that is still owe d such Specified Obligations or has such commitments to extend credit until the date that STX, the Borrower and the Subsidiaries (or any one of them) shall have either (i) delivered to such Secured Party cash collateral in which such Secured Party shall have a first priority security interest in the amount of the Specified Obligations owing to such Secured Party (unless the Secured Party agrees to a lesser amount in its sole discretion), on terms and conditions reasonably satisfactory to such Secured Party or (ii) the Loan Parties have made other collateral arrangements regarding

11

the Specified Obligations owing to, and commitments remaining from, such Secured Party as are reasonably satisfactory to such Secured Party.

(b)  In the event that a Pledgor ceases to be a Subsidiary (as such term is used in the Credit Agreement) pursuant to a transaction permitted under the Loan Documents, such Pledgor shall be released from its obligations under this Agreement and the Collateral of such Pledgor shall be released without further action.

(c)  Upon any sale or other transfer by any Pledgor of any Collateral that is permitted under the Credit Agreement to any Person that is not a Pledgor, or, upon the effectiveness of any written consent to the release of the security interest granted hereby in any Collateral pursuant to Section 9.02 of the Credit Agreement, the security interest in such Collateral shall be automatically released.

(d)  In connection with any termination or release pursuant to paragraph (a), (b) or (c) of this Section 14, the Administrative Agent shall execute and deliver to any Pledgor, at such Pledgor’s expense, all documents that such Pledgor shall reasonably request to evidence such termination or release.  Any execution and delivery of documents pursuant to this Section 14 shall be without recourse to or warranty by the Administrative Agent.

SECTION 15.  [Intentionally Omitted]

SECTION 16.  Notices.  All communications and notices hereunder shall be in writing and given as provided in Section 9.01 of the Credit Agreement.  All communications and notices hereunder to any Subsidiary Pledgor shall be given to it at its address or telecopy number set forth on Schedule I hereto, with a copy to the Borrower.

SECTION 17.  Further Assurances.  Each Pledgor agrees to do such further acts and things, and to execute and deliver such additional conveyances, assignments, agreements and instruments, as the Administrative Agent may at any time reasonably request in connection with the administration and enforcement of this Agreement or with respect to the Collateral or any part thereof or in order better to assure and confirm unto the Administrative Agent its rights and remedies hereunder.

SECTION 18.  Binding Effect; Several Agreement; Assignments.  Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the successors and assigns of such party; and all covenants, promises and agreements by or on behalf of any Pledgor that are contained in this Agreement shall bind and inure to the benefit of each party hereto and their respective successors and assigns.  This Agreement shall become effective as to any Pledgor when a counterpart hereof executed on behalf of such Pledgor shall have been delivered to the Administrative Agent and a counterpart hereof shall have been executed on behalf of the Administrative Agent, and thereafter shall be binding upon such Pledgor and the Administrative Agent and their respective successors and assigns, and shall inure to the benefit of such Pledgor, the Administrative Agent and the other Secured Parties, and their respective successors and assigns, except that no Pledgor shall have the right to assign its rights or obligations

SECTION 8.  All communications and notices hereunder shall be in writing and given as provided in Section 16 of the U.S. Pledge Agreement.  All communications and notices hereunder to the New Pledgor shall be given to it at the address set forth under its signature hereto, below, with a copy to the Borrower.
