The term "Event of Default", wherever used in this Stock Pledge Agreement, shall mean any one or more of the following events, whether or not the occurrence of such event shall, on the part of the Pledgor, be voluntary or involuntary or result or be effected by operation of law 3 4 or pursuant to or in compliance with any judgment, decree or order of a court of competent jurisdiction or any order, rule or regulation of any administrative or governmental body or otherwise: (a) a Default (as such term is used and defined in the Note) shall occur; (b) any representation of the Pledgor contained in Article III hereof shall be inaccurate in any material respect; (c) failure by the Pledgor to perform and comply with any term, covenant, agreement or condition contained in this Stock Pledge Agreement if such failure continues for a period of thirty (30) days after Secured Party gives notice to Pledgor of such failure; (d) the Pledgor shall (i) file, or consent by answer or otherwise to the filing against the Pledgor of, a petition for relief or reorganization or arrangement or any other petition in bankruptcy, or take advantage of any bankruptcy or insolvency law of any jurisdiction, (ii) make an assignment for the benefit of its creditors, (iii) consent to the appointment of a custodian, receiver or similar officer with similar powers with respect to the Pledgor or of any substantial part of the property of the Pledgor, (iv) be adjudicated insolvent or (v) take, approve or permit action for the purpose of any of the foregoing; or (e) a court or governmental authority of competent jurisdiction shall enter an order appointing, without consent of the Secured Party, a custodian, receiver or similar officer with similar powers with respect to the Pledgor or with respect to any substantial part of the property of the Pledgor, or if an order for relief shall be entered in any case or proceeding to take advantage of any bankruptcy or insolvency law of any jurisdiction, or if any petition for any such relief shall be filed against the Pledgor. ARTICLE VII PROCEDURES UPON DEFAULT Section 7.01. Remedies Upon Default. During the continuance of an Event of Default, the Secured Party shall have, the rights and remedies of a secured party under the Uniform Commercial Code as adopted and in effect in Texas as amended from time to time, including without limitation thereto, the right to sell or otherwise dispose of any or all of the Collateral. The Secured Party will send the Pledgor reasonable notice of the time and place of any public sale thereof or of the time after which any private sale or other disposition thereof is to be made. The requirement of sending reasonable notice shall be met if such notice is mailed, postage prepaid, certified or registered mail, to the Pledgor at the address 4 5 designated in this Stock Pledge Agreement at least ten (10) days before the time of the sale or disposition. Section 7.02 Matters Regarding Collateral. Since some or all of the Pledged Stock has not been registered under the Securities Act of 1933 (the "Act"), the Pledgor recognizes that the Secured Party may be required to sell the Collateral privately and that such sale may be made (i) without advertisement or public notice, (ii) after solicitation of only a limited number of sophisticated investors, (iii) pursuant to an investment representation intent and letter from the purchaser thereof, or (iv) pursuant to other procedures that may be necessary, proper or convenient to qualify as a transaction exempt from registration under the Securities Act of 1933 and applicable state securities laws. Pledgor further recognizes that such procedures and restrictions may cause the Pledged Stock to have less value than it otherwise would have, and that the private sale by the Secured Party may result in a lower sales price than if the sale were otherwise held. With knowledge of such facts, the Pledgor specifically agrees that the sale of the Collateral privately by the Secured Party shall be commercially reasonable for all purposes. Pledgor and Secured Party agree that, since other shares of stock of the Company that are of the same class of stock as the Pledged Stock are registered under the Act (the "Registered Stock") and are sold in the National Association of Securities Dealers Automated Quotation System ("NASDAQ") market, the Pledged Stock is of a type customarily sold in a recognized market and is of a type which is the subject of widely distributed standard price quotations, to-wit, price quotations in the NASDAQ market. Accordingly, Pledgor and Secured Party agree that Secured Party may buy at a private sale of the Collateral held pursuant to this Stock Pledge Agreement, and that a purchase price for the Pledged Stock at such a private sale equal to the then current NASDAQ market price applicable to the Registered Stock is commercially reasonable. Section 7.03. Marshaling. The Secured Party shall not be required to marshal any present or future security for (including but not limited to this Stock Pledge Agreement and the Collateral pledged hereunder), or guaranties of, the indebtedness evidenced by the Note or any of them, or to resort to such security or guaranties in any particular order; and all of Secured Party's rights hereunder and in respect of such securities and guaranties shall be cumulative and in addition to all other rights, however, existing or arising. To the extent that it lawfully may, the Pledgor hereby agrees that it will not invoke any law relating to the marshaling of collateral which might cause delay in or impede the enforcement of the Secured Party's rights under this Stock Pledge Agreement or under any other instrument evidencing any of the indebtedness evidenced by the Note or under which any of the indebtedness evidenced by the Note is outstanding or by which any of the indebtedness evidenced by the Note is secured or guaranteed, and to the extent that it lawfully may the Pledgor hereby irrevocably waives the benefits of all such laws. 5 6 ARTICLE VIII MISCELLANEOUS Section 8.01. Rights Cumulative; No Waiver. The rights and privileges hereunder granted are additional, cumulative and concurrent, and the enumeration of certain rights, privileges and options herein shall not be construed as a waiver of, nor to impair, any other rights existing either at law or in equity independently of this Stock Pledge Agreement concerning this or any other liability, obligation, indebtedness or collateral security. Either party may waive any default without waiving any other prior or subsequent default. Section 8.02. Notice. Notices shall be personally delivered or sent by registered or certified mail, postage prepaid, return receipt requested, to the party to receive same at the following addresses or such other addresses as may be specified to the other party hereto in writing: Pledgor's Address: James R.

Further Assurances.

Section 8.04. Secured Party's Exoneration. Except to the extent otherwise required by applicable law, under no circumstances shall the Secured Party be deemed to assume any responsibility for or obligation or duty with respect to any part or all of the Collateral of any nature or kind, other than the physical custody thereof, or any matter or proceedings arising out of or relating thereto. The Secured Party shall not be required to take any action of any kind to collect, preserve or protect its or the Pledgor's rights in the Collateral or against other parties thereto. The Secured Party's prior recourse to any part or all of the Collateral shall not constitute a condition of any demand, suit or proceeding for payment or collection of the indebtedness evidenced by the Note. Section 8.05. No Waiver, Etc. No act (except for an express written waiver), failure or delay by the Secured Party shall constitute a waiver of its rights and remedies hereunder or otherwise. No single or partial waiver by the Secured Party 6 7 of any default, right or remedy which it may have shall operate as a waiver of any other default, right or remedy or of the same default, right or remedy on a future occasion.

Entire Agreement.

If any provision of this Stock Pledge Agreement, or the application thereto to any person or circumstance, shall, for any reason and to any extent, be invalid or unenforceable, the remainder of this Stock Pledge Agreement and the application of such provision to other persons or circumstances shall not be affected thereby, but rather shall be enforced to the greatest extent permitted by law. Section 8.10. Amendments. This Stock Pledge Agreement may be amended or modified by, and only by, a written instrument executed by the Pledgor, and Secured Party or their respective successors, assigns and transferees. Section 8.11. Counterparts. This Stock Pledge Agreement may be executed in counterparts, each of which shall be an original, but all of which together shall constitute one agreement, binding on all of the parties hereto notwithstanding that all of the parties hereto are not signatories to the same counterpart.
