(C) The Trustee shall be deemed without further action or formality to have granted to each Pledgor all necessary consents relating to voting rights and shall, if necessary, upon written request of any Pledgor and at the sole cost and expense of the Pledgors, from time to time execute and deliver (or cause to be executed and delivered) to such Pledgor all such instruments as such Pledgor may reasonably request in order to permit such Pledgor to exercise the voting and other rights which it is entitled to exercise pursuant to Section 5.2(i)(A) hereof and to receive the Distributions which it is authorized to receive and retain pursuant to Section 5.2(i)(B) hereof.

(ii) Upon the occurrence and during the continuance of any Event of Default:

(A) All rights of each Pledgor to exercise the voting and other consensual rights it would otherwise be entitled to exercise pursuant to Section 5.2(i)(A) hereof without any action or the giving of any notice shall cease, and all such rights shall thereupon become vested in the Trustee, which shall thereupon have the sole right to exercise such voting and other consensual rights.

(B) All rights of each Pledgor to receive Distributions which it would otherwise be authorized to receive and retain pursuant to Section 5.2(i)(B) hereof shall cease and all such rights shall thereupon become vested in the Trustee, which shall thereupon have the sole right to receive and hold as Pledged Collateral such Distributions.

(iii) Each Pledgor shall, at its sole cost and expense, from time to time after the occurrence and during the continuance of an Event of Default execute and deliver to the Trustee appropriate instruments as the Trustee may request in order to permit the Trustee to exercise the voting and other rights which it may be entitled to exercise pursuant to Section 5.2(ii)(A)

hereof and to receive all Distributions which it may be entitled to receive under Section 5.2(ii)(B) hereof.

(iv) All Distributions which are received by any Pledgor contrary to the provisions of Section 5.2(ii)(B) hereof shall be received in trust for the benefit of the Trustee, shall be segregated from other funds of such Pledgor and shall immediately be paid over to the Trustee as Pledged Collateral in the same form as so received (with any necessary endorsement).

SECTION 5.3 Operative Agreements. Each Pledgor has delivered to the Trustee true, correct and complete copies of the Operative Agreements and the Pledged Debt Securities Indenture. The Operative Agreements and the Pledged Debt Securities Indenture are in full force and effect, have not as of the date hereof been amended or modified except as disclosed to the Trustee, and there is no existing default by any party thereunder or any event which, with the giving of notice of passage of time or both, would constitute a default by any party thereunder. The Issuer shall deliver to the Trustee a copy of any notice of default given or received by it under the Pledged Debt Securities or the Pledged Debt Securities Indenture within ten days after such Pledgor gives or receives such notice. No Pledgor will terminate or agree to terminate any Operative Agreement or the Pledged Debt Securities Indenture or make any amendment or modification to any Operative Agreement which may have a Collateral Material Adverse Effect, including electing not to treat any Pledged Securities of such Pledgor as a security under 8-103 of the UCC.

SECTION 5.4 Defaults, etc. Such Pledgor is not in default in the payment of any portion of any mandatory capital contribution, if any, required to be made under any agreement to which such Pledgor is a party relating to the Pledged Securities pledged by it, and such Pledgor is not in violation of any other provisions of any such agreement to which such Pledgor is a party, or otherwise in default or violation thereunder. No Securities Collateral pledged by such Pledgor is subject to any defense, offset or counterclaim, nor have any of the foregoing been asserted or alleged against such Pledgor by any Person with respect thereto, and as of the date hereof, there are no certificates, instruments, documents or other writings (other than the Operative Agreements and certificates delivered to the Trustee) which evidence any Pledged Securities of such Pledgor.

SECTION 5.5 Pledged Debt Securities. Upon the occurrence and during the continuance of an event of default under the Pledged Debt Securities, the Trustee acting upon a vote of holders of the outstanding Notes representing at least a majority of the accreted value thereunder shall have the right to direct the Issuer as to whether or not to accelerate the Pledged Debt Securities, make a claim thereunder or otherwise exercise remedies under the Pledged Debt Securities Indenture; provided, that, if such event of default results solely from the failure to timely deliver financial statements to holders of Pledged Debt Securities then the

Trustee shall have such right set forth in this Section 5.5, after the expiration of 60 days from the occurrence of such event of default.

ARTICLE VI

TRANSFERS AND OTHER LIENS

SECTION 6.1 Transfers of and other Liens on Pledged Collateral. Pledgor shall not (i) sell, convey, assign or otherwise dispose of, or grant any option with respect to, any of the Pledged Collateral pledged by it hereunder or (ii) create or permit to exist any Lien upon or with respect to any of the Pledged Collateral pledged by it hereunder, other than (a) the Liens created hereunder and (b) Permitted Liens (as defined in the Indenture).

ARTICLE VII

REMEDIES

SECTION 7.1 Remedies. (a) Upon the occurrence and during the continuance of any Event of Default, the Trustee may from time to time exercise in respect of the Securities Collateral, in addition to the other rights and remedies provided for herein or otherwise available to it:

(i) demand, sue for, collect or receive any money or property at any time payable or receivable in respect of the Pledged Collateral including, without limitation, instructing the obligor or obligors on any agreement, instrument or other obligation constituting part of the Pledged Collateral to make any payment required by the terms of such agreement, instrument or other obligation directly to the Trustee, and in connection with any of the foregoing, compromise, settle, extend the time for payment and make other modifications with respect thereto; provided, however, that in the event that any such payments are made directly to any Pledgor, prior to receipt by any such obligor of such instruction, such Pledgor shall segregate all amounts received pursuant thereto in trust for the benefit of the Trustee and shall promptly (but in no event later than one Business Day after receipt thereof) pay such amounts to the Trustee;

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

(iii) retain and apply the Distributions to the Secured Obligations as provided in Article VIII hereof;

(iv) exercise any and all rights as beneficial and legal owner of the Pledged Collateral, including, without limitation, perfecting assignment of and exercising any and all voting, consensual and other rights and powers with respect to any Pledged Collateral; and

(v) all the rights and remedies of a secured party on default under the UCC, and the Trustee may also in its sole discretion, without notice except as specified in Section 7.2 hereof, sell, assign or grant a license to use the Pledged 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 Trustee’s offices or elsewhere, for cash, on credit or for future delivery, and at such price or prices and upon such other terms as the Trustee may deem commercially reasonable. The Trustee or any other Secured Party or any of their respective Affiliates may be the purchaser, licensee, assignee or recipient of any or all of the Pledged 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 Pledged Collateral sold, assigned or licensed at such sale, to use and apply any of the Secured Obligations owed to such Person as a credit on account of the purchase price of any Pledged Collateral payable by such Person at such sale. Each purchaser, assignee, licensee or recipient at any such sale shall acquire the property sold, assigned or licensed absolutely free from any claim or right on the part of any Pledgor, and each Pledgor hereby waives, to the fullest extent permitted by law, all rights of redemption, stay and/or appraisal which 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 Trustee shall not be obligated to make any sale of Pledged 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. Each Pledgor hereby waives, to the fullest extent permitted by law, any claims against the Trustee arising by reason of the fact that the price at which any Pledged Collateral may have been sold, assigned or licensed at such a private sale was less than the price which might have been obtained at a public sale, even if the Trustee accepts the first offer received and does not offer such Pledged Collateral to more than one offeree.

SECTION 7.2 Notice of Sale. Each Pledgor acknowledges and agrees that, to the extent notice of sale or other disposition of Pledged Collateral shall be required by law, 10 Business Days’ prior notice to such Pledgor of the time and place of any public sale or of the time after which any private sale or other intended disposition is to take place shall be commercially reasonable notification of such matters. No notification need be given to any

Pledgor if it has signed, after the occurrence of an Event of Default, a statement renouncing or modifying any right to notification of sale or other intended disposition.

SECTION 7.3 Waiver of Notice and Claims. Each Pledgor hereby waives, to the fullest extent permitted by applicable law, notice or judicial hearing in connection with the Trustee’s taking possession or the Trustee’s disposition of any of the Pledged Collateral, including, without limitation, any and all prior notice and hearing for any prejudgment remedy or remedies and any such right which such Pledgor would otherwise have under law, and each Pledgor hereby further waives, to the fullest extent permitted by applicable law: (i) all damages occasioned by such taking of possession, (ii) all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Trustee’s rights hereunder and (iii) all rights of redemption, appraisal, valuation, stay, extension or moratorium now or hereafter in force under any applicable law. The Trustee shall not be liable for any incorrect or improper payment made pursuant to this Article VII in the absence of gross negligence or willful misconduct. Any sale of, or the grant of options to purchase, or any other realization upon, any Pledged Collateral shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of the applicable Pledgor therein and thereto, and shall be a perpetual bar both at law and in equity against such Pledgor and against any and all Persons claiming or attempting to claim the Pledged Collateral so sold, optioned or realized upon, or any part thereof, from, through or under such Pledgor.

SECTION 7.4 Certain Sales of Pledged Collateral. (i) Each Pledgor recognizes that, by reason of certain prohibitions contained in law, rules, regulations or orders of any Governmental Authority, the Trustee may be compelled, with respect to any sale of all or any part of the Pledged Collateral, to limit purchasers to those who meet the requirements of such Governmental Authority. Each Pledgor acknowledges that any such sales may be at prices and on terms less favorable to the Trustee than those obtainable through a public sale without such restrictions, and, notwithstanding such circumstances, agrees that any such restricted sale shall be deemed to have been made in a commercially reasonable manner and that, except as may be required by applicable law, the Trustee shall have no obligation to engage in public sales.

(ii) Each Pledgor recognizes that, by reason of certain prohibitions contained in the Securities Act of 1933, as amended (the “Securities Act”), and applicable state securities laws, the Trustee may be compelled, with respect to any sale of all or any part of the Securities Collateral, to limit purchasers to Persons who will agree, among other things, to acquire such Securities Collateral for their own account, for investment and not with a view to the distribution or resale thereof. Each Pledgor acknowledges that any such private sales may be at prices and on terms less favorable to the Trustee than those obtainable through a public sale without such restrictions (including, without limitation, a public offering made pursuant to a registration statement under the Securities Act), and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially

reasonable manner and that the Trustee shall have no obligation to engage in public sales and no obligation to delay the sale of any Securities Collateral for the period of time necessary to permit the issuer thereof to register it for a form of public sale requiring registration under the Securities Act or under applicable state securities laws, even if such issuer would agree to do so.

(iii) Notwithstanding the foregoing, each Pledgor shall, upon the occurrence and during the continuance of any Event of Default, at the reasonable request of the Trustee, for the benefit of the Trustee, cause any registration, qualification under or compliance with any Federal or state securities law or laws to be effected with respect to all or any part of the Securities Collateral as soon as practicable and at the sole cost and expense of the Pledgors. Each Pledgor will use its commercially reasonable efforts to cause such registration to be effected (and be kept effective) and will use its commercially reasonable efforts to cause such qualification and compliance to be effected (and be kept effective) as may be so requested and as would permit or facilitate the sale and distribution of such Securities Collateral including, without limitation, registration under the Securities Act (or any similar statute then in effect), appropriate qualifications under applicable blue sky or other state securities laws and appropriate compliance with all other requirements of any Governmental Authority. Each Pledgor shall use its commercially reasonable efforts to cause the Trustee to be kept advised in writing as to the progress of each such registration, qualification or compliance and as to the completion thereof, shall furnish to the Trustee such number of prospectuses, offering circulars or other documents incident thereto as the Trustee from time to time may request, and shall indemnify and shall cause the issuer of the Securities Collateral to indemnify the Trustee and all others participating in the distribution of such Securities Collateral against all claims, losses, damages and liabilities caused by any untrue statement (or alleged untrue statement) of a material fact contained therein (or in any related registration statement, notification or the like) or by any omission (or alleged omission) to state therein (or in any related registration statement, notification or the like) a material fact required to be stated therein or necessary to make the statements therein not misleading.

(iv) If the Trustee determines to exercise its right to sell any or all of the Securities Collateral, upon written request, the applicable Pledgor shall from time to time furnish to the Trustee all such information as the Trustee may request in order to determine the number of securities included in the Securities Collateral which may be sold by the Trustee as exempt transactions under the Securities Act and the rules of the Securities and Exchange Commission thereunder, as the same are from time to time in effect.

(v) Each Pledgor further agrees that a breach of any of the covenants contained in this Section 7.4 will cause irreparable injury to the Trustee and other Secured Parties, that the Trustee and the other Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 7.4 shall be specifically enforceable against such Pledgor, and such Pledgor hereby waives

and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred and is continuing.

SECTION 7.5 No Waiver; Cumulative Remedies. (i) No failure on the part of the Trustee to exercise, no course of dealing with respect to, and no delay on the part of the Trustee in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right, power or remedy hereunder preclude any other or further exercise thereof or the exercise of any other right, power or remedy; nor shall the Trustee be required to look first to, enforce or exhaust any other security, collateral or guaranties. The remedies herein provided are cumulative and are not exclusive of any remedies provided by law.

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

ARTICLE VIII

APPLICATION OF PROCEEDS

The proceeds received by the Trustee in respect of any sale of, collection from or other realization upon all or any part of the Pledged Collateral pursuant to the exercise by the Trustee of its remedies as a secured creditor as provided in Article VII hereof shall be applied, together with any other sums then held by the Trustee in the manner set forth in the Indenture.

ARTICLE IX

MISCELLANEOUS

SECTION 9.1 Concerning Trustee. (i) The Trustee has been appointed as trustee pursuant to the Indenture. The actions of the Trustee hereunder are subject to the provisions of the Indenture. The Trustee shall have the right hereunder to make demands, to give notices, to exercise or refrain from exercising any rights, and to take or refrain from taking

action (including, without limitation, the release or substitution of the Pledged Collateral), in accordance with this Agreement and the Indenture. The Trustee may employ agents and attorneys-in-fact in connection herewith and shall not be liable for the negligence or misconduct of any such agents or attorneys-in-fact selected by it in good faith. The Trustee may resign and a successor Trustee may be appointed in the manner provided in the Indenture. Upon the acceptance of any appointment as the Trustee by a successor Trustee, that successor Trustee shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Trustee under this Agreement, and the retiring Trustee shall thereupon be discharged from its duties and obligations under this Agreement. After any retiring Trustee’s resignation, the provisions hereof shall inure to its benefit as to any actions taken or omitted to be taken by it under this Agreement while it was the Trustee.

(ii) The Trustee shall be deemed to have exercised reasonable care in the custody and preservation of the Pledged Collateral in its possession if such Pledged Collateral is accorded treatment substantially equivalent to that which the Trustee, in its individual capacity, accords its own property consisting of similar instruments or interests, it being understood that neither the Trustee nor any of the Secured Parties shall have responsibility for (i) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any Securities Collateral, whether or not the Trustee or any other Secured Party has or is deemed to have knowledge of such matters, or (ii) taking any necessary steps to preserve rights against any Person with respect to any Pledged Collateral.

(iii) The Trustee shall be entitled to rely upon any written notice, statement, certificate, order or other document or any telephone message believed by it to be genuine and correct and to have been signed, sent or made by the proper person, and, with respect to all matters pertaining to this Agreement and its duties hereunder, upon advice of counsel selected by it.

SECTION 9.2 Trustee May Perform; Trustee Appointed Attorney-in-Fact. (a) If any Pledgor shall fail to perform any covenants contained in this Agreement (including, without limitation, such Pledgor’s covenants to (i) pay Charges or discharge Liens or (ii) pay or perform any obligations of such Pledgor under any Pledged Collateral) or if any warranty on the part of any Pledgor contained herein shall be breached, the Trustee may (but shall not be obligated to) do the same or cause it to be done or remedy any such breach, and may expend funds for such purpose; provided, however, that Trustee shall in no event be bound to inquire into the validity of any tax, lien, imposition or other obligation which such Pledgor fails to pay or perform as and when required hereby and which such Pledgor does not contest in accordance in accordance with the provision of Section 4.10 hereof. Any and all amounts so expended by the Trustee shall be paid by the Pledgors in accordance with the provisions of Section 9.3 hereof. Neither the provisions of this Section 9.2 nor any action taken by Trustee pursuant to the provisions of this Section 9.2 shall prevent any such failure to observe any covenant contained in this Agreement nor any breach of warranty from constituting an Event

of Default. Each Pledgor hereby appoints the Trustee as its attorney-in-fact, with full authority in the place and stead of such Pledgor and in the name of such Pledgor, or otherwise from time to time in the Trustee’s discretion upon the occurrence and during the continuance of an Event of Default to take any action and to execute any instrument consistent with the terms of the Indenture and this Agreement which the Trustee may deem necessary or advisable to accomplish the purposes hereof; provided, however, that the Trustee shall not have any obligation to make any such determination or to exercise such discretion unless directed to by the Holders pursuant to the Indenture. The foregoing grant of authority is a power of attorney coupled with an interest and such appointment shall be irrevocable for the term hereof. Each Pledgor hereby ratifies all that such attorney shall lawfully do or cause to be done by virtue hereof.

(b) Each Pledgor hereby authorizes the filing of any financing statements or continuation statements, and amendments to financing statements, in any jurisdiction and with any filing offices as the Trustee may determine, in its reasonable discretion, are necessary or advisable to perfect the security interest granted to the Trustee for the benefit of the Secured Parties in connection herewith; provided, however, that the Trustee shall not have any obligation to make any such determination or to exercise such discretion unless directed to by the Holders pursuant to the Indenture. Such financing statements may describe the collateral in the same manner as described in this Agreement or may contain an indication or description of collateral that describes such property in any other manner as the Trustee may determine, in its reasonable discretion, is necessary, advisable or prudent to ensure the perfection of the security interest in the collateral granted to the Trustee for the benefit of the Secured Parties in connection herewith; provided, however, that the Trustee shall not have any obligation to make any such determination or to exercise such discretion unless directed to by the Holders pursuant to the Indenture.

SECTION 9.3 Expenses. Each Pledgor will upon demand pay to the Trustee the amount of any and all reasonable costs and expenses, including the fees and expenses of its counsel and the fees and expenses of any experts and agents which the Trustee may incur in connection with (i) any action, suit or other proceeding affecting the Pledged Collateral or any part thereof commenced, in which action, suit or proceeding the Trustee is made a party or participates or in which the right to use the Pledged Collateral or any part thereof is threatened, or in which it becomes necessary in the judgment of the Trustee to defend or uphold the Lien hereof (including, without limitation, any action, suit or proceeding to establish or uphold the compliance of the Pledged Collateral with any requirements of any Governmental Authority or law), (ii) the collection of the Secured Obligations, (iii) the enforcement and administration hereof, (iv) the custody or preservation of, or the sale of, collection from, or other realization upon, any of the Pledged Collateral, (v) the exercise or enforcement of any of the rights of the Trustee or any Secured Party hereunder or (vi) the failure by any Pledgor to perform or observe any of the provisions hereof. All amounts expended by the Trustee and payable by any Pledgor under this Section 9.3 shall be due upon demand therefor (together

with interest thereon accruing at the highest rate then in effect under the Indenture during the period from and including the date on which such funds were so expended to the date of repayment) and shall be part of the Secured Obligations. Each Pledgor’s obligations under this Section 9.3 shall survive the termination hereof and the discharge of such Pledgor’s other obligations under this Agreement, the Indenture and the other Security Documents.

SECTION 9.4 Indemnity.

(i) Indemnity. Each Pledgor agrees to indemnify, pay and hold harmless the Trustee and each of the other Secured Parties and the officers, directors, employees, agents and Affiliates of the Trustee and each of the other Secured Parties (collectively, the “Indemnitees”) from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs (including, without limitation, settlement costs), expenses or disbursements of any kind or nature whatsoever (including, without limitation, the reasonable fees and disbursements of a single firm of counsel for such Indemnitees in connection with any investigative, administrative or judicial proceeding, commenced or threatened, whether or not such Indemnitee shall be designated a party thereto) which may be imposed on, incurred by, or asserted against that Indemnitee, in any manner relating to or arising out of this Agreement, the Indenture or the Notes, or any other document evidencing the Secured Obligations (including, without limitation, any misrepresentation by any Pledgor in this Agreement, the Indenture or the Notes or any other document evidencing the Secured Obligations) (the “Indemnified Liabilities”); provided, however, that no Pledgor shall have any obligation to an Indemnitee hereunder with respect to Indemnified Liabilities if it has been determined by a final decision (after all appeals and the expiration of time to appeal) of a court of competent jurisdiction that such Indemnified Liabilities arose from the gross negligence, bad faith or willful misconduct of that Indemnitee. To the extent that the undertaking to indemnify, pay and hold harmless set forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, each Pledgor shall contribute the maximum portion which it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all Indemnified Liabilities incurred by the Indemnitees or any of them.

(ii) Survival. The obligations of the Pledgors contained in this Section 9.4 shall survive the termination hereof and the discharge of the Pledgors’ other obligations under this Agreement, the Indenture and the Notes.

(iii) Reimbursement. Any amounts paid by any Indemnitee as to which such Indemnitee has the right to reimbursement shall constitute Secured Obligations secured by the Pledged Collateral.

SECTION 9.5 Continuing Security Interest; Assignment. This Agreement shall create a continuing security interest in the Pledged Collateral and shall (i) be binding upon the Pledgors, their respective successors and assigns and (ii) inure, together with the rights and remedies of the Trustee hereunder, to the benefit of the Trustee and the other

Secured Parties and each of their respective successors, transferees and assigns. No other Persons (including, without limitation, any other creditor of any Pledgor) shall have any interest herein or any right or benefit with respect hereto. Without limiting the generality of the foregoing clause (ii), any Secured Party may assign or otherwise transfer any indebtedness held by it secured by this Agreement to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Secured Party, herein or otherwise, subject however, to the provisions of the Indenture.

SECTION 9.6 Termination; Release. The Pledged Collateral shall be released from the Lien of this Agreement in accordance with the provisions of the Indenture. Upon termination hereof in accordance with the provisions of the Indenture, the Trustee shall, upon the request and at the sole cost and expense of the Pledgors, assign, transfer and deliver to Pledgor, against receipt and without recourse to or warranty by the Trustee, such of the Pledged Collateral to be released (in the case of a release) as may be in possession of the Trustee and as shall not have been sold or otherwise applied pursuant to the terms hereof, and, with respect to any other Pledged Collateral, proper documents and instruments (including financing statement amendments or releases) acknowledging the termination hereof or the release of such Pledged Collateral, as the case may be.

SECTION 9.7 Modification in Writing. No amendment, modification, supplement, termination or waiver of or to any provision hereof, nor consent to any departure by any Pledgor therefrom, shall be effective unless the same shall be made in accordance with the terms of the Indenture and unless in writing and signed by the Trustee. Any amendment, modification or supplement of or to any provision hereof, any waiver of any provision hereof and any consent to any departure by any Pledgor from the terms of any provision hereof shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement or any other document evidencing the Secured Obligations, no notice to or demand on any Pledgor in any case shall entitle any Pledgor to any other or further notice or demand in similar or other circumstances.

SECTION 9.8 Notices. Unless otherwise provided herein or in the Indenture, any notice or other communication herein required or permitted to be given shall be given in the manner and become effective as set forth in the Indenture, as to any Pledgor, addressed to it at the address of the Issuer set forth in the Indenture and as to the Trustee, addressed to it at the address set forth in the Indenture, or in each case at such other address as shall be designated by such party in a written notice to the other party complying as to delivery with the terms of this Section 9.8.

SECTION 9.9 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 9.10 CONSENT TO JURISDICTION AND SERVICE OF PROCESS; WAIVER OF JURY TRIAL. ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST ANY PLEDGOR WITH RESPECT TO THIS AGREEMENT MAY BE BROUGHT IN THE SUPREME COURT OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY, THE COURTS OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK AND APPELLATE COURTS OF ANY THEREOF, AND BY EXECUTION AND DELIVERY HEREOF, EACH PLEDGOR ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS AGREEMENT. EACH PLEDGOR AGREES THAT SERVICE OF PROCESS IN ANY PROCEEDING MAY BE EFFECTED BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL (OR ANY SUBSTANTIALLY SIMILAR FORM OF MAIL), POSTAGE PREPAID, TO THE ISSUER AT ITS ADDRESS SET FORTH IN THE INDENTURE OR AT SUCH OTHER ADDRESS OF WHICH THE TRUSTEE SHALL HAVE BEEN NOTIFIED PURSUANT THERETO. IF ANY AGENT APPOINTED BY ANY PLEDGOR REFUSES TO ACCEPT SERVICE, SUCH PLEDGOR HEREBY AGREES THAT SERVICE UPON IT BY MAIL SHALL CONSTITUTE SUFFICIENT NOTICE. NOTHING HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF THE TRUSTEE TO BRING PROCEEDINGS AGAINST ANY PLEDGOR IN THE COURTS OF ANY OTHER JURISDICTION. THE PLEDGORS HEREBY IRREVOCABLY WAIVE ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

SECTION 9.11 Severability of Provisions. Any provision hereof which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

SECTION 9.12 Execution in Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original, but all such counterparts together shall constitute one and the same agreement.

SECTION 9.14 No Credit for Payment of Taxes or Imposition. Such Pledgor shall not be entitled to any credit against the principal, or accreted value or premium, if any, or interest payable under the Indenture or the Notes, and such Pledgor shall not be entitled to any credit against any other sums which may become payable under the terms thereof or hereof, by reason of the payment of any tax on the Pledged Collateral or any part thereof.

SECTION 9.15 No Claims Against Trustee. Nothing contained in this Agreement shall constitute any consent or request by the Trustee, express or implied, for the performance of any labor or services or the furnishing of any materials or other property in respect of the Pledged Collateral or any part thereof, nor as giving any Pledgor any right, power or authority to contract for or permit the performance of any labor or services or the furnishing of any materials or other property in such fashion as would permit the making of any claim against the Trustee in respect thereof or any claim that any Lien based on the performance of such labor or services or the furnishing of any such materials or other property is prior to the Lien hereof.

SECTION 9.16 Obligations Absolute. All obligations of each Pledgor hereunder shall be absolute and unconditional irrespective of:

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

(ii) any lack of validity or enforceability of the Indenture, the Notes or any other document evidencing the Secured Obligations, or any other agreement or instrument relating thereto;
