"Dividends" shall mean cash dividends declared on or with respect to the Pledged Shares; such term does not include any Distributions. "Pledged Property" shall mean all the Pledged Shares and all other instruments that are now being delivered by the Debtor to, or that may from time to time hereafter be delivered by the Debtor to, the Secured Party or any agent, custodian, or representative of the Secured Party pursuant to this Security Agreement. 2. Security Interest. To secure the payment when due of principal and interest under the Note and the performance of the Debtor's obligations under this Security Agreement and any other agreement with the Secured Party, the Debtor shall and hereby does, on and as of the date hereof, grant, convey, assign, and transfer to the Secured Party a security interest in and to: (a) the Pledged Property together with all Dividends, Distributions, and any rights with respect thereto, and all proceeds of any of the foregoing; (b) all additional shares of stock of the Secured Party at any time and from time to time acquired by the Debtor in any manner and the certificates representing such additional shares, and also cash, securities, dividends, rights, and other property at any time and from time to time received, receivable, or otherwise distributed with respect to or in exchange for any or all of the additional shares subject to this Section 2 (b); and (c) all other property hereafter delivered to the Secured Party in substitution for or in addition to any of the foregoing, all certificates and instruments representing or evidencing such property, and all cash, securities, interest, Dividends, Distributions, rights, and other property at any time and from time to time received, receivable, or otherwise distributed with respect to or in exchange for any or all thereof; together with interest, profits, Dividends, and Distributions arising there- from, and in the case of intangible property, all voting (provided, however, that so long as no default exists hereunder or under the Note, the Debtor shall have the right to vote all shares of stock that are held as Collateral), surrender, borrowing, redemption, or similar rights, and all accruals or increases thereof, or substitutions thereof (all such Pledged Property, Dividends, Distributions, notes, instruments, cash, securities, interests, rights, and other property being herein collec- tively called the "Collateral"). 3. Default. 3.1 Events of Default. Under the Note and this Security Agreement, any one or more of the following shall constitute an "Event of Default": (a) The Debtor shall fail to make a payment of interest or principal on the Note when the same shall have become due; (b) Default shall occur in the observance or performance of any other material provision of the Note, this Security Agreement, or any other agreement between the Debtor and the Secured Party; or (c) The Debtor becomes insolvent or bankrupt, is generally unable to pay debts as they become due, makes an assignment for the benefit of creditors, causes or suffers an order for relief to be entered against it under applicable federal bankruptcy law, or applies for or consents to the appointment of a custodian, trustee, liquidator, or receiver for the Debtor or for the major part of its property. 3.2 Remedies. Upon the occurrence of an Event of Default, the Secured Party shall have all rights and remedies available to it under this Security Agreement, the Note, and under the Uniform Commercial Code and any other applicable law. 3.2.1 Whenever a default shall be existing, the Note, notwithstanding any provisions thereof to the contrary, at the option of the Secured Party and without demand or notice of any kind, be declared, and thereupon immediately shall become, due and payable, and the Secured Party may exercise from time to time any rights and remedies available to it under this Security Agreement. The Debtor hereby waives presentment, demand, protest, and any notice (to the extent permitted by applicable law) of any kind in connection with this Security Agreement. 3.2.2 The Secured Party shall be entitled to recover all of its costs, including but not limited to attorneys' fees, incurred with respect to the collection of the amounts due under the Note and under the terms of this Security Agreement from the proceeds of the sale of the Collateral. 3.2.3 Any proceeds of any disposition of the Collateral may be applied by the Secured Party to the payment of expenses incurred in connection with the Collateral, including without limitation reasonable attorneys' fees and legal expenses, and any balance of such proceeds may be applied by the Secured Party toward the payment of the amounts due under the Note. 3.2.4 If any notification of intended disposition of any of the Collateral is required by law, such notification, if mailed, shall be deemed reasonably and properly given if mailed at least five days before such disposition, postage prepaid, addressed to the Debtor, either at the address of the Debtor as shown herein or at any other address of the Debtor appearing on the records of the Secured Party. 3.2.5 All of the Secured Party's rights and remedies expressed hereunder are in addition to all other rights and remedies possessed by the Secured Party, including those under any other agreement or instrument relating to any of the liabilities or security therefor. No delay on the Secured Party's part in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by the Secured Party of any right or remedy shall preclude other or further exercise thereof or the exercise of any right or remedy. No action by the Secured Party permitted hereunder shall impair or affect its rights in and to the collateral. 3.2.6 The Debtor agrees that in any sale of any of the Collateral pursuant to a Default, the Secured Party is hereby authorized to comply with any limitation or restriction in connection with such sale as it may be advised by counsel as necessary in order to avoid any violation of applicable law (including, without limitation, compliance with such procedures as may restrict the number of prospective bidders and purchasers, require that such prospective bidders and purchasers have certain qualifications, and restrict such prospective bidders and purchasers to persons who will represent and agree that they are pur- chasing for their own account for investment and not with a view to the distribution or resale of such Collateral), or in order to obtain any required approval of the sale or of the purchaser by any governmental regulatory authority or official, and the Debtor further agrees that such compliance shall not result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall the Secured Party be liable nor accountable to the Debtor for any discount allowed by reason of the fact that such Collateral is sold in compliance with any such limitation or restriction. 3.2.7 No delay or omission of the Secured Party to exercise any right, remedy or power shall impair the same or be construed to be a waiver of any Event of Default or an acquiescence thereto. No waiver of any Event of Default shall extend to or affect any subsequent Event of Default or impair any rights, remedies, or powers available to the Secured Party. The acceptance by the Secured Party at any time and from time to time of partial payment of the Note shall not be deemed to be a waiver of any default then existing. If any waiver is granted by the Secured Party, it will be under no obligation to give notice to the Debtor that future waivers will not be granted. 4. Representations and Warranties of The Debtor. To induce the Secured Party to enter into the transactions provided for herein, the Debtor represents and warrants to the Secured Party that: 4.1 The Debtor is duly authorized to execute and deliver this Security Agreement and the Note and to perform all of its obligations thereunder, including the execution, delivery, and performance of whatever additional documents are necessary or required in connection with the transactions that are contemplated herein. 4.2 The execution and delivery by the Debtor of this Security Agreement and the Note and the performance by the Debtor of its obligations under this Security Agreement and the Note do not and will not conflict with any provision of law or of any other agreement affecting or binding upon the Debtor. 4.3 This Security Agreement and the Note, when duly executed and delivered, will be valid and binding obligations of the Debtor enforceable in accordance with their respective terms, except as limited by bankruptcy, insolvency, or other laws of general application relating to the enforcement of creditors' rights. 5.
