OBLIGATIONS OF GRANTOR.  Grantor warrants and covenants to Lender as follows:

Perfection of Security Interest.  Grantor agrees to execute such financing statement and to take whatever other actions are requested by Lender to perfect and continue Lender’s security interest in the Collateral.  Upon request of Lender, Grantor will deliver to Lender any and all of the documents evidencing or constituting the Collateral, and Grantor will note Lender’s interest upon any and all chattel paper if not delivered to Lender for possession by Lender.  Grantor hereby appoints Lender as its irrevocable attorney-in-fact for the purpose of executing any documents necessary to perfect or to continue the security interest granted in this Agreement.  Lender may at any time, and without further authorization from Grantor, file a carbon, photographic or other reproduction of any financing statement or of this Agreement for use as a financing statement. Grantor will reimburse Lender for all expenses for the perfection and the continuation of the perfection of Lender’s security interest in the Collateral.  Grantor promptly will notify Lender before any change in Grantor’s name including any change to the assumed business names of Grantor.  This is a continuing Security Agreement and will continue in effect even though all or any part of the Indebtedness is paid in full and even though for a period of time Grantor may not be indebted to Lender.

No Violations.  The execution and delivery of this Agreement will not violate any law or agreement governing Grantor or to which Grantor is a party, and its certificate or articles of incorporation and bylaws do not prohibit any term or condition of this Agreement.

Enforceability of Collateral.  To the extent the Collateral consists of accounts, chattel paper, or general intangibles, the Collateral is enforceable in accordance with its terms, is genuine, and complies with applicable laws concerning form, content and manner of preparation and execution, and all persons appearing to be obligated on the Collateral have authority and capacity to contract and are in fact obligated as they appear to be on the Collateral.

Location of the Collateral.  Grantor, upon request of Lender, will deliver to Lender in form satisfactory to Lender a schedule of real properties and Collateral locations relating to Grantor’s operations, including without limitation the following: (a) all real property owned or being purchased by Grantor; (b) all real property being rented or leased by Grantor; (c) all storage facilities owned, rented, leased, or being used by Grantor; and (d) all other properties where Collateral is or may be located.  Except in the ordinary course of its business, Grantor shall not remove the Collateral from its existing locations without the prior written consent of Lender.

Removal of Collateral.  Grantor shall keep the Collateral (or to the extent the Collateral consists of intangible property such as accounts, the records concerning the Collateral) at Grantor’s address shown above, or at such other locations as are acceptable to Lender.  Except in the ordinary course of its business, including the sales of inventory, Grantor shall not remove the Collateral from its existing locations without the prior written consent of Lender.  To the extent that the Collateral consists of vehicles, or other titled property, Grantor shall not take or permit any action which would require application for certificates of title for the vehicles outside the State of Texas, without the prior written consent of Lender.

Transactions Involving Collateral.  Except for inventory sold or accounts collected in the ordinary course of Grantor’s business, Grantor shall not sell, offer to sell, or otherwise transfer or

3

dispose of the Collateral.  While Grantor is not in default under this Agreement, Grantor may sell inventory, but only in the ordinary course of its business and only to buyers who qualify as a buyer in the ordinary course of business.  A sale in the ordinary course of Grantor’s business does not include a transfer in partial or total satisfaction of a debt or any bulk sale.  Grantor shall not pledge, mortgage, encumber or otherwise permit the Collateral to be subject to any lien, security interest, encumbrance, or charge, other than the security interest provided for in this Agreement, without the prior written consent of Lender.  This includes security interests even if junior in right to the security interests granted under this Agreement.  Unless waived by Lender, all proceeds from any disposition of the Collateral (for whatever reason) shall be held in trust for Lender and shall not be commingled with any other funds; provided however, this requirement shall not constitute consent by Lender to any sale or other disposition.  Upon receipt, Grantor shall immediately deliver any such proceeds to Lender.

Title.  Grantor represents and warrants to Lender that it holds good and marketable title to the Collateral, free and clear of all liens and encumbrances except for the lien of this Agreement.  No financing statement covering any of the Collateral is on file in any public office other than those which reflect the security interest created by this Agreement or to which Lender has specifically consented.  Grantor shall defend Lender’s rights to the Collateral against the claims and demands of all other persons.

Collateral Schedules and Locations.  Insofar as the Collateral consists of inventory, Grantor shall deliver to Lender, as often as Lender shall require, such lists, descriptions, and designations of such Collateral as Lender may require to identify the nature, extent, and location of such Collateral.  Such information shall be submitted for Grantor and each of its subsidiaries or related companies.

Maintenance and Inspection of Collateral.  Grantor shall maintain all tangible Collateral in good condition and repair.  Grantor will not commit or permit damage to or destruction of the Collateral or any part of the Collateral.  Lender and its designated representatives and agents shall have the right at all reasonable times to examine, inspect, and audit the Collateral wherever located.  Grantor shall immediately notify Lender of all cases involving the return, rejection, repossession, loss or damage of or to any Collateral; of any request for credit or adjustment or of any other dispute arising with respect to the Collateral; and generally of all happenings and events affecting the Collateral or the value or the amount of the Collateral.

Taxes, Assessments and Liens.  Grantor will pay when due all taxes, assessments and liens upon the Collateral, its use or operation, upon this Agreement, upon any promissory note or notes evidencing the Indebtedness, or upon any of the other Related Documents.  Grantor may withhold any such payment or may elect to contest any lien if Grantor is in good faith conducting an appropriate proceeding to contest the obligation to pay and so long as Lender’s interest in the Collateral is not jeopardized in Lender’s sole opinion.  If the Collateral is subjected to a lien which is not discharged within fifteen (15) days, Grantor shall deposit with Lender cash, a sufficient corporate surety bond or other security satisfactory to Lender in an amount adequate to provide for the discharge of the lien plus any interest, costs, attorneys’ fees or other charges that could accrue as a result of foreclosure or sale of the Collateral.  In any contest Grantor shall defend itself and Lender and shall satisfy any final adverse judgment before enforcement against the Collateral.  Grantor shall name Lender as an additional obligee under any surety bond furnished in the contest proceedings.

4

Compliance with Governmental Requirements.  Grantor shall comply promptly with all laws, ordinances, rules and regulations of all governmental authorities, nor or hereafter in effect, applicable to the ownership, production, disposition, or use of the Collateral.  Grantor may contest in good faith any such law, ordinance or regulation and withhold compliance during any proceeding, including appropriate appeals, so long as Lender’s interest in the Collateral, in Lender’s opinion, is not jeopardized.

EXPENDITURES BY LENDER.  If not discharged or paid when due, Lender may (but shall not be obligated to) discharge or pay any amounts required to be discharged or paid by Grantor under this Agreement, including without limitation all taxes, liens, security interests, encumbrances, and other claims, at any time levied or placed on the Collateral.  Lender also may (but shall not be obligated to) pay all costs for insuring, maintaining and preserving the Collateral.  All such expenditures incurred or paid by Lender for such purposes will then bear interest at the Note rate from the date incurred or paid by Lender to the date of repayment by Grantor.  All such expenses shall become a part of the Indebtedness and, at Lender’s option, will (a) be payable on demand, (b) be added to the balance of the Note and be apportioned among and be payable with any installment payments to become due during either (i) the term of any applicable insurance policy or (ii) the remaining term of the Note, or (c) be treated as a balloon payment which will be due and payable at the Note’s maturity.  This Agreement also will secure payment of these amounts.  Such right shall be in addition to all other rights and remedies to which Lender may be entitled upon the occurrence of an Event of Default.

EVENTS OF DEFAULT.  Each of the following shall constitute an Event of Default under this Agreement:

Default on Indebtedness.  Failure of Grantor to make any payment when due on the Indebtedness.

Default in Favor of Third Parties.  Should Borrower or any Grantor default under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower’s property or Borrower’s or Grantor’s ability to repay the Loans or perform their respective obligations under this Agreement or any of the Related Documents.

False Statements.  Any warranty, representation or statement made or furnished to Lender by or on behalf of Grantor under this Agreement, the Note or the Related Documents is false or misleading in any material respect, either now or at the time made or furnished.

Defective Collateralization.  This Agreement or any of the Related Documents ceases to be in full force and effect (including failure of any collateral documents to create a valid and perfected security interest or lien) at any time and for any reason.

Sell the Collateral.  Lender shall have full power to sell, lease, transfer, or otherwise deal with the Collateral or proceeds thereof in its own name or that of Grantor.  Lender may sell the Collateral at public auction or private sale.  Unless the Collateral threatens to decline speedily in value or is of a type customarily sold on a recognized market, Lender will give Grantor reasonable notice of the time after which any private sale or any other intended disposition of the Collateral is to be made.  The requirements of reasonable notice shall be met if such notice is given at least ten (10) days before the time of the sale or disposition.  All expenses relating to the disposition of the Collateral, including without limitation the expenses of retaking, holding, insuring, preparing for sale and selling the Collateral, shall become a part of the Indebtedness secured by this Agreement and shall be payable on demand, with interest at the Note rate from date of expenditure until repaid.

Other Rights and Remedies.  Lender shall have all the rights and remedies of a secured creditor under the provisions of the Uniform Commercial Code, as may be amended from time to time.  In addition, Lender shall have and may exercise any or all other rights and remedies it may have available at law, in equity, or otherwise.

Cumulative Remedies.  All of Lender’s rights and remedies, whether evidenced by this Agreement or the Related Documents or by any other writing, shall be cumulative and may be exercised singularly or concurrently.  Election by Lender to pursue any remedy shall not exclude pursuit of any other remedy, and an election to make expenditures or to take action to perform an obligation of Grantor under this Agreement, after Grantor’s failure to perform, shall not affect Lender’s right to declare a default and to exercise its remedies.
