the security interests granted hereunder constitute, under the Code, valid security interests in all Collateral, securing the Obligations and (i) upon the delivery of any of the Collateral to the Bank in accordance herewith, the security interest in such Collateral will be perfected, subject to no prior lien and the Bank will have "control" (as defined in the Code) thereof, (ii) with respect to Collateral, if any, in the possession of a third party, the Bank will have a perfected, first priority security interest in such Collateral upon execution by such third party of a control agreement in form and substance satisfactory to the Bank and (iii) when UCC financing statements in the appropriate form are filed in the appropriate offices, the security interest granted hereunder will constitute a perfected security interest to the extent that a security interest may be perfected by filing pursuant to the Code, prior to all liens and rights of others;

the Pledgor has full power and authority to enter into this Agreement and to pledge the Collateral hereunder and except for the filing of UCC financing statements, no registration, recordation or filing with any governmental body, agency or official is required in connection with the execution or delivery hereof or is necessary for the validity or enforceability thereof or for the perfection or due recordation of the security interest granted hereunder or for the enforcement thereof;

as to Collateral, if any, comprised of deposit accounts, the Pledgor has delivered to the Bank every certificate of deposit included in the Collateral, duly endorsed to the Bank and every passbook or other document or instrument evidencing or comprising the Collateral; and

all shares of capital stock identified in any Schedule to this Agreement are beneficially owned by the Pledgor, have been duly authorized and validly issued, are fully paid and non‑assessable, and are subject to no option to purchase or similar right of any person.  The Pledgor is not and will not become a party to or otherwise bound by any agreement (including without limitation any voting agreement), other than the Loan Documents, which restricts in any manner the rights of any present or future holder of any Collateral with respect thereto.

Power of Attorney.  The Pledgor hereby irrevocably constitutes and appoints the Bank as the Pledgor's true and lawful attorney, with full power of substitution at the sole cost and expense of the Pledgor but for the sole benefit of the Bank, to endorse in favor of the Bank any of the Collateral; execute and deliver instruments of assignment and/or orders for withdrawal; cause the transfer of any of the Collateral in such name as the Bank may, from time to time, determine; cause the issuance of certificates for book entry and/or uncertificated securities; provide notification in connection with book entry securities or general intangibles and/or provide instructions to the issuers of uncertificated securities or securities intermediaries, as necessary; to renew, extend or roll over any Collateral; and make demand and initiate actions to enforce any of the Obligations.  The Bank may take such action with respect to the Collateral as the Bank may reasonably determine to be necessary to protect and preserve its interests in the Collateral.  The Bank shall also have and may exercise at any time all rights, remedies, powers, privileges and discretion of the Pledgor with respect to and under the Collateral, provided, however, the Bank shall have no right until an Event of Default has occurred to exercise any voting rights available to the Pledgor at any time the Collateral is held by the Bank solely as pledgee hereunder.  Except as limited above, all the rights, remedies, powers, privileges and discretion included in this paragraph may be exercised by the Bank whether or not any of the Obligations are then due and whether or not an Event of Default has occurred.  All powers conferred upon Bank by this Agreement, being coupled with an interest, shall be irrevocable until this Agreement terminates in accordance with its terms, all Obligations are irrevocably paid in full and the Collateral is released.  The power of attorney shall not be affected by subsequent disability or incapacity of the Pledgor.  The Bank shall not be liable for any act or omission to act pursuant to this Paragraph except for any act or omission to act which is caused by the Bank's gross negligence or willful misconduct.

Further Assurances.  The Pledgor will from time to time execute and deliver to the Bank such documents, and take or cause to be taken, all such other further action, as the Bank may reasonably request in order to effect and confirm or vest more securely in the Bank all rights contemplated by this Agreement (including, without limitation, to correct clerical errors) or to vest more fully in, or assure to the Bank the security interest in, the Collateral or to comply with applicable statute or law.  To the extent permitted by applicable law, the Pledgor authorizes the Bank to file financing statements, continuation statements or amendments, and any such financing statements, continuation statements or amendments may be filed at any time in any jurisdiction.  The Bank may at any time and from time to time file financing statements, continuation statements and amendments thereto which contain any information required by Article 9 of the Code for the sufficiency or filing office acceptance of any financing statement, continuation statement or amendment, including whether the Pledgor is an organization, the type of organization and any organization identification number issued to the Pledgor.  The Pledgor agrees to furnish any such information to the Bank promptly upon request.  In addition, the Pledgor shall at any time and from time to time take such steps as the Bank may reasonably request for the Bank (i) to obtain an acknowledgment, in form and substance satisfactory to the Bank, of any bailee having possession of any of the Collateral that the bailee holds such Collateral for the Bank, (ii) to obtain "control" of any Collateral comprised of investment property or deposit accounts (as such terms are defined in the Code), with any agreements establishing control to be in form and substance satisfactory to the Bank, and (iii) otherwise to insure the continued perfection and priority of the Bank's security interest in any of the Collateral and the preservation of its rights therein.  The Pledgor hereby constitutes the Bank its attorney-in-fact to execute and file all filings required or so requested for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; and such power, being coupled with an interest, shall be irrevocable until this Agreement terminates in accordance with its terms, all Obligations are irrevocably paid in full and the Collateral is released.

Default.  If an Event of Default shall occur, at the election of the Bank (but automatically in the case of an Insolvency Default), all Obligations shall become immediately due and payable without notice or demand, except with respect to Obligations payable on demand, which shall be due and payable on demand, whether or not an Event of Default has occurred.

Safe Custody and Exclusivity.  The Bank shall have no duty as to the Collateral or protection of the Collateral or any income or distribution thereon, beyond the safe custody of such of the Collateral as may come into the possession of the Bank with the same due care that the bank with which the Bank would maintain its own property, and shall have no duty as to the preservation of rights against prior parties or any other rights pertaining thereto.  The Bank's Rights and Remedies (as defined herein) may be exercised without resort or regard to any other source of satisfaction of the Obligations.

Indemnification.  The Pledgor shall indemnify, defend and hold the Bank and any Bank Affiliate and their directors, officers, employees, agents and attorneys (each an "Indemnitee") harmless of and from any claim brought or threatened against any Indemnitee by the Pledgor, any guarantor or endorser of the Obligations, or any other person (as well as from attorneys' reasonable fees and expenses in connection therewith) on account of the Bank's relationship with the Pledgor, or any guarantor or endorser of the Obligations (each of which may be defended, compromised, settled or pursued by the Bank with counsel of the Bank's election, but at the expense of the Pledgor), except for any claim arising out of the gross negligence or willful misconduct of the Bank.  The within indemnification shall survive payment of the Obligations, and/or any termination, release or discharge executed by the Bank in favor of the Pledgor.

Waivers.  The Pledgor waives notice of intent to accelerate, notice of acceleration, notice of nonpayment, demand, presentment, protest or notice of protest of the Obligations, and all other notices, consents to any renewals or extensions of time of payment thereof, and generally waives any and all suretyship defenses and defenses in the nature thereof.  No course of dealing and no delay or omission of the Bank in exercising or enforcing any of its rights, powers, privileges, remedies, immunities or discretion (all of which are hereinafter collectively referred to as the "Bank's Rights and Remedies") hereunder or under applicable law shall constitute a waiver thereof; and no waiver by the Bank of any default of the Pledgor hereunder or of any demand hereunder shall operate as a waiver of any other default hereunder or any other demand hereunder.  No term or provision hereof shall be waived, altered or modified except with the prior written consent of the Bank, which consent makes explicit reference to this Agreement.  Except as provided in the preceding sentence, no other agreement or transaction, of whatsoever nature, entered into between the Bank and the Pledgor at any time (whether before, during or

after the effective date or term of this Agreement) shall be construed in any particular way as a waiver, modification or limitation of any of the Bank's Rights and Remedies under this Agreement (nor shall anything in this Agreement be construed as a waiver, modification or limitation of any of the Bank's Rights and Remedies under any such other agreement or transaction) but all the Bank's Rights and Remedies not only under the provisions of this Agreement but also under any such other agreement or transaction shall be cumulative and not alternative or exclusive, and may be exercised by the Bank at such time or times and in such order of preference as the Bank in its sole discretion may determine.

Severability.  If any provision of this Agreement or portion of such provision or the application thereof to any person or circumstance shall to any extent be held invalid or unenforceable, the remainder of this Agreement (or the remainder of such provision) and the application thereof to other persons or circumstances shall not be affected thereby.
