SECTION 2. Security for Obligations. This Pledge Agreement secures, and the Collateral is collateral security for, (x) the prompt and complete payment and performance when due of the full amount of each of the first six scheduled payments of interest on the Notes and (y) for the period beginning on the date of this Pledge Agreement and ending on the scheduled date for the sixth scheduled payment of interest on the Notes, the prompt and complete payment and performance when due (whether at stated maturity, by acceleration or otherwise) of all the Obligations of the Pledgor, whether for principal, interest, Liquidated Damages, fees or otherwise, now or hereafter existing, under this Pledge Agreement, the Notes or the Indenture (all such obligations being the "Secured Obligations"). SECTION 3. Maintaining the Pledged Account. So long as any Secured Obligation shall remain outstanding: (a) The Pledgor will maintain separately the Pledged Account with the Account Holder. (b) It shall be a term and condition of the Pledge Agreement, notwithstanding any term or condition to the contrary in any other agreement relating to the Pledged Account, and except as otherwise provided by Section 5 and Section 18 hereof, that no funds shall be paid or released to or for the account of, or withdrawn by or for the account of, the Pledgor or any other Person from the Pledged Account except as expressly provided in this Pledge Agreement. The Pledged Account shall be subject to such applicable laws, and such applicable regulations of the Board of Governors of the Federal Reserve System and of any other appropriate banking or governmental authority, as may now or hereafter be in effect. SECTION 4. Delivery of Collateral. (a) All certificates or instruments representing or evidencing the Pledged Financial Assets or the Pledged Security Entitlements shall be delivered to and held by or on behalf of the Trustee pursuant hereto and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance satisfactory to the Trustee. The Trustee shall have the right, at any time in its discretion and without notice to the Pledgor, to transfer to or to register in the name of the Trustee or any of its nominees any or all of the Collateral. In addition, the Trustee shall have the right at any time to exchange certificates or instruments representing or evidencing any or all of the Collateral for certificates or instruments of smaller or larger denominations. Also, the Trustee shall have the right at any time to convert Collateral consisting of financial assets credited to the Pledged Account to Collateral consisting of financial assets held directly by the Trustee, and to convert Collateral consisting of financial assets held directly by the Trustee to Collateral consisting of financial assets credited to the Pledged Account. 3 (a) With respect to any Collateral in which the Pledgor has any right, title or interest and that constitutes an uncertificated security, the Pledgor shall cause the issuer thereof either (i) to register the Trustee as the registered owner of such security or (ii) to agree in writing with the Pledgor and the Trustee that such issuer will comply with instructions with respect to such security originated by the Trustee without further consent of the Pledgor, such agreement to be in form and substance satisfactory to the Trustee. (b) With respect to any Collateral in which the Pledgor has any right, title or interest and that constitutes a security entitlement, the Pledgor shall cause the securities intermediary with respect to such security entitlement either (i) to identify in its records the Trustee as the entitlement holder of such security entitlement against such securities intermediary or (ii) to agree in writing with the Pledgor and the Trustee that such securities intermediary will comply with entitlement orders (that is, notifications communicated to such securities intermediary directing transfer or redemption of the financial asset to which the Pledgor has a security entitlement) originated by the Trustee without further consent of the Pledgor, such agreement to be in substantially the form of Annex A hereto or otherwise in form and substance satisfactory to the Trustee. (c) With respect to any Collateral that constitutes a securities account, the Pledgor will comply with subsection (c) of this Section 4 with respect to all security entitlements held in such securities account. (d) Prior to or concurrently with the execution and delivery hereof and prior to the transfer to the Trustee of the Pledged Security Entitlements, as provided in subsections (a) through (c) of this Section 4, the Trustee shall establish the Pledged Account with the Account Holder. Upon transfer of the Pledged Financial Assets to the Trustee, as confirmed to the Trustee by the securities intermediary, the Trustee shall make appropriate book entries indicating that the Pledged Financial Assets have been credited to and are held in the Pledged Account. Subject to the other terms and conditions of this Pledge Agreement, all funds or other property held by the Trustee pursuant to this Pledge Agreement shall be held in the Pledged Account subject (except as expressly provided in Sections 5(a), (b) and (c) hereof) to the exclusive control (as defined in Section 8-106 of the UCC) of the Trustee and exclusively for the benefit of the Trustee and for the ratable benefit of the Holders of the Notes and segregated from all other funds or other property otherwise held by the Trustee. (e) All Collateral shall be retained in the appropriate account pending disbursement pursuant to the terms hereof. (f) Concurrently with the execution and delivery of this Pledge Agreement, the Trustee shall deliver to the Pledgor a duly executed Control Agreement (the "Control Agreement"), in the form of Annex A hereto. (g) Concurrently with the execution and delivery of this Pledge Agreement, the Trustee shall deliver to the Pledgor a duly executed Control Agreement (the "Control Agreement"), in the form of Annex A hereto. SECTION 5. Disbursements. (a) Three business days prior to the due date of any of the first six scheduled interest payments on the Notes, the Pledgor may, pursuant to written instructions given by the Pledgor to the Trustee (an "Issuer Order"), direct the Trustee to release from the Pledged Account and pay to the Holders of the Notes proceeds to provide for payment, in whole or in part, of such interest then due on the Notes. Upon receipt of an Issuer 4 Order, the Trustee will (i) issue a Payment Order (as defined in the Control Agreement) to the Account Holder for the release from the Pledged Account of such funds to the Trustee in accordance with such Issuer Order and (ii) pay such funds to the Holders of the Notes in accordance with the Indenture and the Notes. In the event that the funds released from the Pledged Account on any interest payment date are not sufficient to pay in full the interest due on the Notes on such interest payment date (a "Shortfall"), nothing in this Section 5 shall relieve the Pledgor of its obligations under the Notes and the Indenture to pay such Shortfall to the Holders of the Notes on such interest payment date; provided, however, that no such Shortfall shall be paid from proceeds of the Collateral unless such proceeds constitute a Surplus (as defined below). Furthermore, nothing in this Pledge Agreement shall relieve the Pledgor of its obligations under the Notes and the Indenture to pay Liquidated Damages, if any. In the event that the funds available for release from the Pledged Account on any interest payment date exceed the interest due on the Notes on such interest payment date (a "Surplus"), such Surplus shall be retained in the Pledged Account and may be applied to the next Shortfall(s), if any. Nothing in this Section 5 shall affect the Trustee's rights to apply the Collateral to the payments of amounts due on the Notes upon acceleration thereof. (b) If the Pledgor makes any of the first six scheduled interest payments on the Notes or portion of such an interest payment from a source of funds other than the Pledged Account ("Pledgor Funds"), the Pledgor may, after payment in full of such interest payment, direct the Trustee pursuant to an Issuer Order to issue a Payment Order (as defined in the Control Agreement) to the Account Holder for the release to the Pledgor or to another party at the direction of the Pledgor (the "Pledgor's Designee") proceeds from the Pledged Account in an amount less than or equal to the amount of Pledgor Funds applied to such interest payment; provided, however, that the foregoing shall not apply in the event that such payment of Pledgor Funds is made in order to compensate for any Shortfall. Upon receipt by the Trustee of such Issuer Order and provided the Trustee has received such interest payment, the Trustee shall direct the Account Holder pursuant to a Payment Order to pay over to the Pledgor or the Pledgor's Designee, as the case may be, the requested amount from proceeds in the Pledged Account as soon as practicable. (c) At least three Business Days prior to the due date of each of the first six scheduled interest payments on the Notes, the Pledgor shall give the Trustee notice (by Issuer Order) as to whether such interest payment will be made pursuant to Section 5(a) or 5(b) above and the respective amounts of interest that will be paid from the Pledged Account and from Pledgor Funds. Any Pledgor Funds to be used to make any interest payment shall be delivered to the Trustee, in immediately available funds, prior to 10:00 a.m. (New York City time) on such interest payment date. If no such notice is given or such Pledgor Funds have not been so delivered, the Trustee will act pursuant to Section 5(a) above as if it had received an Issuer Order pursuant thereto for the payment of the interest then due from the Pledged Account. (d) The Trustee shall instruct the Account Holder to liquidate Collateral in the Pledged Account (pursuant to written instructions from the Pledgor) in order to make any of the scheduled payments of interest on the Notes, unless there are sufficient funds in the Pledged Account on such interest payment date. The Trustee shall be entitled to instruct the Account Holder to sell any Collateral as contemplated hereunder prior to the maturity of such Collateral and shall not be responsible for any costs and expenses of such sale. 5 (e) Nothing contained in this Pledge Agreement shall (i) afford the Pledgor any right to issue entitlement orders with respect to any of the Pledged Security Entitlements or any securities account in which any such security entitlement may be carried, or otherwise afford the Pledgor control of any Pledged Security Entitlement or (ii) otherwise give rise to any rights of the Pledgor with respect to the Pledged Financial Assets or any securities account in which any such security entitlement may be carried, other than the Pledgor's rights under this Pledge Agreement as the beneficial owner of collateral pledged to and subject to the exclusive control (except as expressly provided in Sections 5(a) and (b) hereof prior to an Event of Default) of the Trustee in its capacity as such (and not as a securities intermediary) before the payment in full, when due, of the first six scheduled interest payments on the Notes. The Pledgor acknowledges, confirms and agrees that the Trustee is an entitlement holder of the Pledged Security Entitlements solely as Trustee for the Holders of the Notes and not as a securities intermediary. SECTION 6. Investing of Amounts in the Pledged Account. If requested and as directed in writing by the Pledgor, the Trustee will, subject to the provisions of Sections 3, 5 and 13 of this Pledge Agreement, from time to time, instruct the Account Holder to invest interest paid on the Pledged Financial Assets and reinvest other proceeds of any Pledged Financial Assets that may mature or be sold, in each case, in (i) identified United States Treasury securities or (ii) selected shares of a money market fund registered under the Investment Company Act of 1940, as amended, the portfolio of which consists of United States Treasury securities, in each case credited to the Pledged Account. For tax reporting and withholding purposes, all income earned on investments held by the Trustee shall be allocated to the Pledgor and, within ten days after the date of this Pledge Agreement, the Pledgor shall provide such tax reporting documents to the Trustee as the Trustee may request.

(e) The execution and delivery by the Pledgor of, and the performance by the Pledgor of its obligations under, this Pledge Agreement will not contravene any provision of applicable law or the Articles of Incorporation of the Pledgor or any material agreement or other material instrument binding upon the Pledgor or any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Pledgor, or result in the creation or imposition of any Lien on any assets of the Pledgor, except for the security interests granted under this Pledge Agreement. (f) No consent of any other person and no approval, authorization, order of, action by, notice to, filing or qualification with, any governmental authority, regulatory body, agency or other third party is required for (i) the grant by the Pledgor of the pledge and security interest granted under this Pledge Agreement, (ii) the execution or delivery by the Pledgor of, or the performance by the Pledgor of its obligations under, this Pledge Agreement, (iii) the perfection or maintenance of the pledge and security interest created hereunder (including the first priority nature of such pledge or security interest), except for the filing of financing and continuation statements under the UCC, which financing statements have been delivered to the Trustee and which, when filed, shall be in full force and effect, or (iv) for the exercise by the Trustee of its voting or other rights provided for in this Pledge Agreement or the remedies in respect of the Collateral pursuant to this Pledge Agreement, except as may be required in connection with the disposition of any portion of the Collateral by laws affecting the offering and sale of securities generally.

Without limiting the generality of the foregoing, the Pledgor will: (i) if any Collateral shall be evidenced by a promissory note or other instrument, deliver and pledge to the Trustee hereunder such note or instrument, duly endorsed and accompanied by duly executed instruments of transfer or assignment, all in form and substance satisfactory to the Trustee; (ii) execute and file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as the Trustee may reasonably request, in order to perfect and preserve the pledge and security interest granted or purported to be granted hereby; (iii) deliver and pledge to the Trustee for its benefit and the ratable benefit of the Holders of the Notes certificates representing Collateral that constitutes certificated securities, accompanied by undated stock or bond powers executed in blank; and (iv) deliver to the Trustee evidence that all other action that the Trustee may deem reasonably necessary or desirable in order to perfect and protect the security interest created by the Pledgor under this Pledge Agreement has been taken.

Such financing statements may describe the Collateral by reference to an attached photocopy or other reproduction of this Pledge Agreement, or in any manner similar in scope to the description of the Collateral provided in Section 1. The Pledgor ratifies its authorization for the Trustee to have filed such financing statements, continuation statements or amendments filed prior to the date hereof.

SECTION 10. Power of Attorney. In addition to all of the powers granted to the Trustee pursuant to the Indenture, the Pledgor hereby irrevocably appoints the Trustee as the Pledgor's attorney-in-fact (with full power of substitution), with full authority in the place and stead of the Pledgor and in the name of the Pledgor or otherwise, from time to time in the Trustee's discretion after the occurrence and during the continuance of an Event of Default, to take any action and to execute any instrument that is necessary or advisable or as the Trustee may deem necessary or advisable to accomplish the purposes of this Pledge Agreement, including, without limitation, to: (a) ask for, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral, 9 (b) receive, indorse and collect any drafts or other instruments, documents and chattel paper, in connection with clause (a) above, (c) file any claims or take any action or institute any proceedings that the Trustee may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Trustee with respect to any of the Collateral, and (d) pay or discharge taxes or Liens levied or placed upon the Collateral that the Pledgor has failed to pay or discharge in accordance herewith, the legality or validity thereof and the amounts necessary to discharge the same to be determined by the Trustee in its sole reasonable discretion, and such payments made by the Trustee to become part of the Obligations of the Pledgor to the Trustee, due and payable immediately upon demand; provided, however, that the Trustee shall have no obligation to perform any of the foregoing actions. The Trustee's authority under this Section 10 shall include, without limitation, the authority to endorse and negotiate any checks or instruments representing proceeds of Collateral in the name of the Pledgor, execute and give receipt for any certificate of ownership or any document constituting Collateral, transfer title to any item of Collateral, or any other documents deemed necessary or appropriate by the Trustee to preserve, protect or perfect the security interest in the Collateral granted hereunder and to file the same, prepare, file and sign the Pledgor's name on any notice of Lien, and to take any other actions arising from or incident to the powers granted to the Trustee in this Pledge Agreement. This power of attorney is coupled with an interest and is irrevocable by the Pledgor. If the Pledgor fails to perform any agreement contained herein, the Trustee may, but without obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the expenses of the Trustee incurred in connection therewith shall be payable by the Pledgor under Section 12 hereof. SECTION 11. No Assumption of Duties; Reasonable Care. The powers conferred on the Trustee hereunder are solely to protect the security interest of the Trustee for its benefit and the ratable benefit of the Holders of the Notes in the Collateral and shall not impose any duty on the Trustee to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Trustee shall have no duty as to any Collateral for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not the Trustee has or is deemed to have knowledge of such matters, (ii) taking any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral or (c) investing or reinvesting any of the Collateral or any loss on any investment. The Trustee shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which it accords its own property. The Trustee shall be entitled to all the rights, benefits, privileges and immunities accorded to it under the Indenture. SECTION 12. Indemnity and Expenses. (a) The Pledgor agrees to indemnify, defend and save and hold harmless the Trustee, and each Holder of Notes and their respective officers, directors, employees, agents and advisors (each, an "Indemnified Party") from and 10 against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or resulting from this Pledge Agreement (including, without limitation, enforcement of this Pledge Agreement), except to the extent such claim, damage, loss, liability or expense is from such Indemnified Party's gross negligence or willful misconduct. (b) The Pledgor will, within five business days after demand, pay to the Trustee the amount of any and all reasonable fees and expenses, including, without limitation, the reasonable fees and expenses of its counsel and of any experts and agents, that the Trustee may incur in connection with (i) the review and negotiation of the Indenture and this Pledge Agreement, (ii) the custody or preservation of, or the sale of, collection from or other realization upon, any of the Collateral, (iii) the exercise or enforcement of any of the rights of the Trustee or the Holders of the Notes hereunder or (iv) the failure by the Pledgor to perform or observe any of the provisions hereof. SECTION 13. Remedies. If any Event of Default under the Indenture (including, without limitation, any default hereunder constituting an Event of Default (any such Event of Default being referred to in this Pledge Agreement as an "Event of Default")) shall have occurred and be continuing and payments on the Notes shall have been accelerated in accordance with the provisions of the Indenture: (a) The Trustee and the Holders of the Notes may exercise in respect of the Collateral, in addition to all other rights and remedies given by law or by this Pledge Agreement or the Indenture, all of the rights and remedies of a secured party under the UCC (whether or not the UCC applies to the affected Collateral) and also may without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at any broker's board or at public or private sale, in one or more sales or lots, at any of the Trustee's offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Trustee may deem commercially reasonable. The Pledgor agrees that, to the extent notice of sale shall be required by law, at least 10 days' notice to the Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Trustee shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Trustee 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. The purchaser of any or all Collateral so sold shall thereafter hold the same absolutely, free from any claim, encumbrance or right of any kind whatsoever created by or through the Pledgor. Any sale of the Collateral conducted in conformity with reasonable commercial practices of banks, insurance companies, commercial finance companies, or other financial institutions disposing of property similar to the Collateral shall be deemed to be commercially reasonable. The Trustee or any Holder of Notes may, in its own name or in the name of a designee or nominee, buy any of the Collateral at any public sale and, if permitted by applicable law, at any private sale. All expenses (including court costs and reasonable attorneys' fees, expenses and disbursements) of, or incident to, the enforcement of any of the provisions hereof shall be recoverable from the proceeds of the sale or other disposition of the Collateral. 11 (b) Any cash held by or on behalf of the Trustee and all cash proceeds received by or on behalf of the Trustee in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall (after payment of any amounts payable to the Trustee pursuant to Section 12(b) of this Pledge Agreement) be promptly released by the Trustee for payment to the Holders of the Notes and be applied first to any accrued and unpaid interest on the Notes, second, to the repayment of the principal amount of the Notes and Liquidated Damages (if any) on the Notes, and third, to the extent available, against the remaining Secured Obligations. Any surplus of such cash or cash proceeds held by or on behalf of the Trustee and remaining after payment in full of all the Secured Obligations shall be paid over to the Pledgor or to whomsoever may be lawfully entitled to receive such surplus. (c) The Trustee may, without notice to the Pledgor except as required by law and at any time or from time to time, charge, set-off and otherwise apply all or any part of the Collateral against the Secured Obligations or any part thereof. (d) The Pledgor agrees to (i) provide the Trustee with such information as may be necessary, or in the opinion of the Trustee, advisable to enable the Trustee to effect the sale of the Collateral and (ii) use its reasonable best efforts to do or cause to be done all such other acts and things as may be necessary to make such sale or sales of all or any portion of the Collateral pursuant to this Section 13 valid and binding and in compliance with any and all other applicable requirements of law. SECTION 14. Security Interest Absolute. This Pledge Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Secured Obligations is rescinded or must otherwise be returned by the Trustee or any Holder of the Notes or by any other Person upon the insolvency, bankruptcy or reorganization of the Pledgor or otherwise, all as though such payment had not been made. SECTION 15. Amendments, Waivers and Consents. No amendment or waiver of any provision of this Pledge Agreement, and no consent to any departure by the Pledgor from any provision of this Pledge Agreement, shall in any event be effective unless the same shall be in writing and signed by the Trustee and the Pledgor, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure on the part of the Trustee or any Holder of the Notes to exercise, and no delay in exercising any right hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. SECTION 16. Notices. Any notice or communication given hereunder shall be sufficiently given if in writing and delivered in person or mailed by first class mail, commercial courier service or telecopier communication, addressed as follows; or, as to any party, at such other address as shall be designated by such party in a written notice to the other parties: 12 if to the Pledgor: Thoratec Corporation 6035 Stoneridge Drive Pleasanton, California 94588 Attention: General Counsel Telephone: (925) 847-6000 Fax: (925) 847-8574 with a copy to: Gibson, Dunn & Crutcher LLP One Montgomery Street, Suite 3100 San Francisco, California 94104 Attention: Gregory J.

The Pledgor agrees that it will not assert any counterclaims, setoffs or crossclaims in any proceeding brought by the Trustee to realize on such property or to enforce a judgment or other court order in favor of the Trustee, 15 except for such counterclaims, setoffs or crossclaims which, if not asserted in any such proceeding, could not otherwise be brought or asserted.

Sch - 1 ANNEX A CONTROL AGREEMENT This CONTROL AGREEMENT (this "Agreement") dated as of May 24, 2004 by and among Thoratec Corporation (the "Pledgor") and U.S. Bank National Association, in its capacity as trustee (the "Trustee"), and U.S. Bank National Association, a national banking association, in its capacity as securities intermediary and depository bank (the "Account Holder"). PRELIMINARY STATEMENTS: (1) The Pledgor has granted the Trustee a security interest (the "Security Interest") in certain security entitlements (the "Pledged Security Entitlements") with respect to certain U.S. Treasury securities (the "Pledged Financial Assets") identified on Schedule I attached hereto maintained by the Trustee with the Account Holder and carried from time to time in an account with the Account Holder, ABA No. 091000022, Account No. 785834000, and entitled "Thoratec Corporation Senior Subordinated Convertible Notes due 2034, Collateral Pledge Account" (the "Pledged Account") and all additions thereto and substitutions and proceeds thereof (collectively, the "Collateral"), pursuant to, and as more particularly described in, a Pledge Agreement dated as of May 18, 2004, among the Pledgor and the Trustee (as the same may hereafter be amended, supplemented or otherwise modified from time to time, the "Pledge Agreement"; terms defined in the Pledge Agreement and not otherwise defined herein are used herein as therein defined). The Pledgor acknowledges having received value for such pledge of the Collateral. (2) Terms defined in Article 8 or 9 of the Uniform Commercial Code as in effect in the State of New York (the "UCC") are used in this Agreement (including, without limitation, paragraph (1) above) as such terms are defined in such Article 8 or 9. (3) The Pledgor, the Trustee and the Account Holder are delivering this Agreement pursuant to the terms of the Pledge Agreement. NOW, THEREFORE, in consideration of the premises and mutual agreements contained herein, the parties hereto hereby agree as follows: SECTION 1. Notice of Exclusive Control. The Pledgor and Trustee are entering into this Agreement to perfect, and confirm the first priority lien of, the Trustee's Security Interest in the Collateral. The Account Holder agrees to promptly make all necessary entries or notations in its books and records to reflect the Trustee's Security Interest in the Collateral and to apply any value distributed on account of any Pledged Financial Assets as directed in writing by the Trustee without further consent from the Pledgor. The Account Holder acknowledges that the Trustee has exclusive control over the Pledged Account and all Pledged Security Entitlements contained therein from time to time. A - 1 SECTION 2. The Account. The Account Holder represents and warrants to, and agrees with, the Pledgor and the Trustee and the Holders of the Notes that: (a) The Account Holder has established the Pledged Account and shall not change the name or account number of the Pledged Account without the prior written consent of the Trustee. (b) The Account Holder maintains the Pledged Account for the Trustee, and all property (including, without limitation, all funds and financial assets) held by the Account Holder for the account of the Trustee is, and will continue to be, credited to the Pledged Account. The Account Holder is a securities intermediary (as defined in Section 8-102(a)(xiv) of the UCC) and is acting in such capacity in relation to the Trustee, the Pledgor and the Pledged Account and with respect to all property credited thereto, from time to time. (c) The Pledged Account is a securities account. The Account Holder is the securities intermediary with respect to financial assets credited to the Pledged Account from time to time. The Trustee is the entitlement holder with respect to financial assets credited from time to time to the Pledged Account. (d) All financial assets in registered form or payable to or to the order of and credited to the Pledged Account shall be registered in the name of, payable to or to the order of, or endorsed to, the Account Holder and in no case during the term of the Pledge Agreement will any financial asset credited to the Pledged Account be registered in the name of, payable to or to the order of, or endorsed to, the Pledgor, except to the extent the foregoing have been subsequently endorsed by the Pledgor to the Account Holder or in blank. (e) Notwithstanding any other agreement to the contrary, the Account Holder's jurisdiction with respect to the Pledged Account for purposes of the UCC is, and will continue to be for so long as the Security Interest shall be in effect, the State of New York. (f) The Account Holder does not know of any claim to or interest in the Pledged Account or any property (including, without limitation, all funds and financial assets) credited to the Pledged Account, except for claims and interests of the parties referred to in this Agreement. SECTION 3. Control by Trustee. (a) The Account Holder will comply with (A) all written instructions directing disposition of the funds in the Pledged Account (such instructions, a "Payment Order"), (B) all notifications and entitlement orders that the Account Holder receives directing it to transfer or redeem any financial asset in the Pledged Account and (C) all other directions concerning the Collateral, including, without limitation, directions to distribute to the Trustee proceeds of any such transfer or redemption or interest on any property in the Pledged Account (any such instruction, notification or direction referred to in clause (A), (B) or (C) above being an "Account Direction"), in each case of clauses (A), (B) and (C) above originated by the Trustee without further consent by the Pledgor or any other person. (b) The Trustee hereby acknowledges that it shall maintain and exercise control of the Pledged Account on behalf of the Holders of the Notes. A - 2 (c) The Account Holder will not (i) comply with Account Directions or other directions concerning the Collateral originated by the Pledgor or (ii) distribute to the Pledgor interest or other distributions on or in respect of the Collateral, unless instructed to do so by the Trustee, in its absolute discretion. SECTION 4. Priority of Trustee's Security Interest. (a) The Account Holder (i) hereby subordinates to the Security Interest and in favor of the Trustee any security interest, lien, or right of setoff the Account Holder may have, now or in the future, against the Pledged Account or property in the Pledged Account, and (ii) agrees that it will not exercise any right in respect of any such security interest or lien or any such right of setoff until the Security Interest is terminated, except that the Account Holder will retain its prior lien on property in the Pledged Account to secure payment for property purchased for the Pledged Account and normal commissions and fees for the Pledged Account. (b) The Account Holder will not enter into any other agreement with any Person relating to Account Directions or other directions with respect to the Pledged Account. SECTION 5. Statements, Confirmations, and Notices of Adverse Claims. (a) The Account Holder will send copies of all statements and confirmations for the Pledged Account simultaneously to the Pledgor and the Trustee. So long as the Trustee and the Account Holder are the same institution, the Account Holder is not required to send copies of statements and confirmations as provided in the preceding sentence. (b) When the Account Holder knows of any claim or interest in the Pledged Account or any property credited to the Pledged Account other than the claims and interests of the parties referred to in this Agreement, the Account Holder will promptly notify the Trustee and the Pledgor of such claim or interest. SECTION 6. The Account Holder's Responsibility. (a) The Account Holder will not be liable to the Pledgor or the Trustee or the Holders of the Notes for complying with an Account Direction or other direction concerning the Collateral originated by the Trustee, even if the Pledgor notifies the Account Holder that the Trustee is not legally entitled to issue the Account Direction or such other direction unless the Account Holder takes the action after it is served with an injunction, restraining order, or other legal process enjoining it from doing so, issued by a court of competent jurisdiction, and had a reasonable opportunity to act on the injunction, restraining order or other legal process. (b) This Agreement does not create any obligation of the Account Holder except for those expressly set forth in this Agreement, in Part 5 of Article 8 of the UCC, or in Article 4 of the UCC. In particular, the Account Holder need not investigate whether the Trustee is entitled under the Trustee's agreements with the Pledgor to give an Account Direction or other direction concerning the Pledged Account. The Account Holder may conclusively rely on notices and communications it believes given by the appropriate party. (c) In no event shall the Account Holder or any of its affiliates, shareholders, directors, officers, employees or agents be liable for indirect, special, punitive, incidental or consequential damages of any kind whatsoever even if advised of the possibility of such A - 3 damages, other than such damages caused by its own bad faith, gross negligence or willful misconduct. (d) Without limiting the foregoing, and notwithstanding any provision to the contrary elsewhere, the Account Holder and its affiliates, shareholders, directors, officers, employees or agents: (i) shall have no responsibilities, obligations or duties in respect of the subject matter hereof other than those expressly set forth in this Agreement, and no implied duties, responsibilities, covenants or obligations shall be read into this Agreement against the Account Holder. Without limiting the foregoing, the Account Holder shall have no duty or authority to determine and/or investigate whether or not an event of default exists under any agreement between the Pledgor and the Trustee, or to determine and/or investigate whether or not the Trustee is entitled to give any Account Direction with respect to the Collateral; (ii) may in any instance where the Account Holder determines that it lacks or is uncertain as to its authority to take or refrain from taking certain action hereunder, or as to any of the requirements of this Agreement under the circumstance before it, delay or refrain from taking any action unless and until it shall have received appropriate written instructions from the Trustee or advice from legal counsel selected by it (or other appropriate advisor), as the case may be, detailing the action required to be taken hereunder and the Account Holder may rely conclusively on any such instructions or advice; (iii) so long as it and they shall have acted (or refrained from acting) in good faith and within the reasonable belief that such action or omission is duly authorized or within the discretion or powers granted to it hereunder, shall not be responsible or liable for any error of judgment in any action taken, suffered or omitted by it or them, or for any act done or step taken or omitted, or for any mistake of fact or law, unless such action constitutes gross negligence or willful misconduct as finally determined by a non-appealable judgment of a court of competent jurisdiction on its (or their) part; (iv) will not be responsible or liable to the Pledgor, the Trustee, or any other person or entity whatsoever for the due execution, legality, validity, enforceability, genuineness, effectiveness or sufficiency of this Agreement (provided, however, that the Account Holder warrants that the Account Holder has legal capacity and has been duly authorized to enter into this Agreement) or for any statement, warranty or representation made by any other party in connection with this Agreement; (v) will not incur any responsibility or liability by acting or not acting in reliance upon advice of counsel, or upon any notice, consent, certificate, instruction, Account Direction, statement, wire instruction, telecopy or other writing reasonably and in good faith believed by it or them to be genuine and in conformance with this Agreement and signed or sent by the proper party or parties and contemplated herein; and (vi) shall not be required to expend or risk its or their own funds, or to take any action (including the institution or defense of legal proceedings) which in its or their reasonable judgment may cause it or them to incur or suffer any expense or liability, unless the A - 4 Account Holder shall have been provided with security or indemnity, acceptable to Account Holder in its sole discretion, for the payment of the costs, expenses (including reasonable attorneys' fees) and liabilities which may be incurred therein or thereby. (e) If any Collateral subject to this Agreement is at any time attached or levied upon, or in case the transfer or delivery of any such Collateral shall be stayed or enjoined, or in the case of any other legal process or judicial order affecting such Collateral, the Account Holder is authorized to comply with any such order in any manner as the Account Holder or its legal counsel reasonably deems appropriate. The Account Holder shall give prompt written notice to the Pledgor and the Trustee of any such attachment, levy, stay, injunction or legal process. If the Account Holder complies with any process, order, writ, judgment or decree relating to the Collateral subject to this Agreement, then the Account Holder shall not be liable or responsible to the Pledgor, the Trustee, or any other person or entity whatsoever even if such order, writ, judgment, decree or process is subsequently modified, vacated or otherwise determined to have been without legal force or effect. (f) The Account Holder shall not be liable or responsible for any delays or failures in performance of any of its duties hereunder which result from events or conditions beyond its reasonable control and so long as the same exist or continue and cannot reasonably be remedied by the Account Holder in accordance with its normal business practices. Such events or conditions shall include, but shall not be limited to, acts of God, strikes, lockouts, riots, acts of war or terrorism, epidemics, nationalization, expropriation, currency restrictions, governmental regulations superimposed after the fact, fire, communication line failures (including the unavailability of the Federal Reserve Bank wire or telex or other wire or communication facility), power failures, earthquakes or other disasters. (g) Subject to the provisions hereof, so long as the Account Holder and the Trustee are the same institution, the Account Holder may rely on written directions given by the Pledgor to the Trustee (including but not limited to Issuer Orders) and shall not require separate corresponding instructions from the Trustee (including but not limited to Payment Orders). SECTION 7. Indemnity. The Pledgor will indemnify the Account Holder, its officers, directors, employees and agents against claims, liabilities and expenses arising out of this Agreement (including, without limitation, reasonable attorney's fees and disbursements), except to the extent the claims, liabilities or expenses are caused by the Account Holder's gross negligence or willful misconduct. SECTION 8. Termination; Survival. (a) This Agreement shall terminate automatically upon receipt by the Account Holder of written notice executed by an authorized officer of the Trustee that (i) all of the Secured Obligations have been paid in full in cash or otherwise satisfied or (ii) all of the Collateral has been released, whichever is earlier, and the Account Holder shall thereafter be relieved of all duties and obligations hereunder. The Account Holder may terminate this Agreement on 60 days' prior notice to the Trustee and the Pledgor, provided that before such termination the Account Holder and the Pledgor shall make arrangements to transfer the property in the Pledged Account to another securities intermediary that shall have executed, together with the Trustee and the Pledgor, a control agreement in favor A - 5 of the Trustee and the Holders of the Notes in respect of such property in substantially the form of this Agreement or otherwise in form and substance satisfactory to the Trustee. (b) In the event that the Trustee no longer serves as Trustee for the Collateral, the Trustee, the Account Holder and the Pledgor shall make arrangements for another Person to assume the rights and obligations of the Trustee hereunder, and such Person shall have executed, together with the Account Holder and the Pledgor, a control agreement in favor of such Person and the Holders of the Notes in substantially the form of this Agreement or otherwise in form and substance satisfactory to the Trustee. (c) Sections 7 and 8 will survive termination of this Agreement. SECTION 9. Conflict with Other Agreements. (a) In the event of any conflict between this Agreement (or any portion thereof) and any other agreement now existing or hereafter entered into, the terms of this Agreement shall prevail. (b) The Account Holder hereby confirms and agrees that: (i) There are no other agreements entered into between the Account Holder and the Pledgor with respect to the Pledged Account; (ii) It has not entered into, and until the termination of this Agreement will not enter into, any agreement with any other person relating to the Pledged Account and/or any financial assets credited thereto or funds therein pursuant to which it has agreed to comply with entitlement orders (as defined in Section 8-102(a)(8) of the UCC) of such other person; and (iii) It has not entered into, and until the termination of this Agreement will not enter into, any agreement with the Pledgor or the Trustee purporting to limit or condition the obligation of the Account Holder to comply with Account Directions as set forth in Section 3 hereof.

In accordance with the Pledge Agreement, the Trustee shall direct the Account Holder with respect to the selection of investments to be made with the funds in the Pledged Account. SECTION 11.
